Description

  The present invention relates to a direction regulating device for a cylindrical container that aligns the circumferential position of the cylindrical container conveyed in an upright state by a conveyor in a certain direction.

In general, containers (tubular containers) filled with cosmetics, medicines, beverages, etc., are shipped by a conveyor in order to ship with a label on which the product name, contents, etc. are attached at a fixed position on the container surface. By the direction regulating device, the circumferential position of the cylindrical container is aligned in a certain direction until the cylindrical container is conveyed upright and supplied to the label sticking device.
Conventionally, as a direction regulating device for this type of cylindrical container, a conveyor for placing and transporting bottles in an upright state, a pair of belts that abut against the cap of the bottle from both sides and run in parallel with the conveyor, A drive device that drives the pair of belts with a difference in speed, and the bottle caps that are aligned by the guide and conveyed by the conveyor are sandwiched between the pair of belts that run from both sides of the bottle, and the belt speed difference And the bottle is rotated to a predetermined position within the belt travel section (see, for example, Patent Document 1).
In addition, a pair of direction restriction belts that run along both sides of the conveyor that carries the containers placed upright is placed with a required interval corresponding to the diameter of the container, and the pair of direction restriction belts are moved at a speed. The containers that are moved in different directions or moved in different directions and aligned in a row by a guide and fed between the pair of direction regulating belts are engaged by engaging their body portions with the respective direction regulating belts. It is known that a predetermined surface on its outer periphery is directed in a certain direction by rotating in a direction (see, for example, Patent Document 2).

  However, both of the conventional cylindrical container direction regulating devices require two container rotation belts for rotating the cylindrical container in the circumferential direction on both sides of the conveyor, and the rotation of the pair of containers. Since it is necessary to provide a guide for aligning and feeding the containers between the belts, there is a problem that the structure of the apparatus is complicated, the manufacturing cost is increased, and maintenance and inspection are complicated.

  The present invention has been made in view of the above circumstances, and provides a small and inexpensive cylindrical container direction regulating device capable of accurately aligning the circumferential position of the cylindrical container in a certain direction with a simple configuration. The purpose is to do.

  In order to solve the above-mentioned problems, the present invention relates to a cylindrical container direction regulating device, in which a cylindrical container having protrusions or recesses on its outer peripheral portion is placed on a conveyor in an upright state and conveyed in a certain direction. On the other hand, the direction restricting device for the cylindrical container aligns the circumferential position of the cylindrical container in a certain direction by the direction restricting means, and the direction restricting means engages with a protrusion or a recess of the cylindrical container. A plurality of engaging projections to be obtained are provided at intervals in the length direction, and an endless cord-like member wound around a driving pulley and a driven pulley, and the driving pulley is rotated to circulate the cord-like member. A drive motor that moves the guide member and a guide member that guides the cylindrical container in contact with the outer peripheral surface thereof, and the cord-like member and the guide member are spaced apart from each other at a predetermined distance from the conveyor transport surface by a predetermined distance. Open and convey the conveyor The distance necessary for the end portions on the downstream side in the conveying direction of the conveyor to pass through the cylindrical containers one by one downstream with respect to Only the cylindrical container which is set at a position nearer to the inner side than the end in the width direction of the conveyor and is conveyed by the conveyor and brought into contact with the guide member has its protrusion or recess engaged with the protrusion of the cord member. When being engaged, it is moved along the guide member from the upstream position in the conveying direction of the conveyor toward the downstream position while maintaining the engaged state.

  In this cylindrical container direction regulating device, the cylindrical container that is randomly transported from the upstream side to the downstream side without being aligned in a line by the conveyor contacts the guide member of the direction regulating means. Then, it rotates in the circumferential direction while making contact with the inclined surface of the guide member, and when the projection or recess faces toward the cord-like member side, it sequentially engages with the engagement projection of the cord-like member, and this engagement makes it cylindrical. After the container is regulated in the circumferential rotational position, the container is conveyed downstream along the guide member in accordance with the movement of the cord-like member while maintaining the regulated rotational position, and from the downstream end. It leaves and is transported to the downstream side of the conveyor.

  In the cylindrical container direction regulating device, if the guide member has a configuration in which a friction applying portion is provided on a surface facing the upstream side in the conveying direction of the conveyor, the cylindrical container is reliably rotated in the circumferential direction. Since the protrusions or recesses are reliably directed toward the cable-shaped member, the engagement protrusions of the cable-shaped member can be easily engaged with the protrusions or recesses of the cylindrical container.

In the cylindrical container direction regulating device, it is preferable that the guide member is provided so that the position of the guide member in the conveyance direction of the conveyor can be adjusted.
In this way, the distance between the tubular container that contacts the guide member and the cord-like member can be adjusted, so that the engagement state of the engagement projection of the cord-like member with respect to the projection or recess of the cylindrical container Can be adjusted appropriately.

In the cylindrical container direction regulating device, the cord-like member may be formed by turning over a transmission timing belt.
According to this, since the cord-like member is easily available as an off-the-shelf product, and the cord-like member has flexibility, it can flexibly contact the projection or recess of the cylindrical container conveyed by the conveyor without impact. In addition, the cylindrical container can be moved smoothly and silently to the downstream side while performing rotational positioning of the cylindrical container, and there is no possibility of damaging the cylindrical container.

In the cylindrical container direction regulating device, it is preferable to provide a guide plate that guides the cable-shaped portion along the back surface of the cable-shaped portion that moves on the upstream side of the conveyor direction of the cable-shaped member. .
If it does in this way, it can prevent that the said cable-like member bends by contact | abutting of the said cylindrical container, The engagement protrusion is firmly engaged with the protrusion or recessed part of a cylindrical container, and a cable-like The cylindrical container can be moved to the downstream end of the member while reliably maintaining the circumferential positioning of the cylindrical container.

In the direction regulating device for the cylindrical container, it is preferable that the moving speed of the cord-like member is set lower than the conveying speed of the conveyor.
In this way, when the cylindrical container moves to the downstream end of the guide member, the protrusion or recess of the cylindrical container is quickly and smoothly detached from the engaging protrusion of the cord-like member. The containers are transported downstream of the conveyor without causing a positional shift of the protrusions or recesses positioned in the circumferential direction.

  In addition, the direction restriction device for a cylindrical container according to the present invention includes a cylindrical container having protrusions or recesses on the outer peripheral portion thereof placed on a conveyor in an upright state and conveyed in a fixed direction by a direction restriction means. A cylindrical container direction regulating device for aligning the circumferential position of the cylindrical container in a fixed direction, wherein the direction regulating means includes an outer peripheral portion of the cylindrical container and a protrusion or a concave portion conveyed by the conveyor. An engagement guide member that engages with a surface facing the upstream side in the transport direction of the conveyor is disposed at a predetermined interval upward from the transport surface of the conveyor and inclined at a predetermined tilt angle with respect to the transport direction of the conveyor. The end of the engagement guide member on the downstream side in the conveying direction of the conveyor is a distance necessary for passing the cylindrical containers one by one downstream from the end in the width direction of the conveyor. Inside It is characterized in that is set in position.

  In this cylindrical container direction regulating device, the cylindrical container that is randomly transported from the upstream side to the downstream side without being aligned in a line by the conveyor is used as the engagement guide member of the direction regulating means. When abutting, it rotates in the circumferential direction while contacting the inclined surface of the engagement guide member, and the outer peripheral portion and the protrusion or the concave portion engage with the surface facing the upstream side in the conveying direction of the conveyor. By the way, the circumferential position of the cylindrical container is restricted. Thereafter, the cylindrical container is transported to the downstream side along the engagement guide member as the conveyor moves to the downstream side in the transport direction while maintaining the regulated rotational position, and the downstream end portion And is transported downstream of the conveyor.

In this cylindrical container direction regulating device, the guide surface is along the surface of the engagement guide member facing the upstream side in the conveyor conveyance direction at the end of the engagement guide member on the downstream side in the conveyance direction of the conveyor. The horizontal swivel between the first position extended outward in the width direction of the conveyor and the second position where the guide surface extends outward in the width direction of the conveyor and extends downstream from the end in the conveying direction of the conveyor. A turning guide member is provided, and the turning guide member is turned to the second position by the turning drive means when the outer peripheral portion of the cylindrical container and the protrusion are engaged with the guide surface at the first position. It is preferable to adopt a configuration.
In this way, when the cylindrical container moves away from the engagement guide member and moves to the downstream side of the conveyor, the phenomenon that the cylindrical container positioned in the circumferential direction turns around to the back side of the engagement guide member is prevented. Therefore, the cylindrical container is conveyed to the downstream side of the conveyor without causing a positional shift of the protrusions or recesses positioned in the circumferential direction.

  In each of the cylindrical container direction regulating devices, if the inclination angle of the guide member or the engagement guide member with respect to the conveyor conveyance direction can be changed and adjusted, the cylindrical container shape size, the conveyor conveyance speed, etc. can be accommodated. Thus, the circumferential speed of the cylindrical container can be smoothly adjusted by appropriately adjusting the moving speed of the cylindrical containers that move downstream along the guide member or the engagement guide member. .

  According to the direction control device for a cylindrical container according to the present invention, the cylindrical container that is randomly conveyed from the upstream side to the downstream side by the conveyor contacts the guide member or the engagement guide member of the direction control means. Then, the protrusion or recess is engaged with the cord-like member by rotating in the circumferential direction, or is engaged with the engagement guide member, and the engagement ensures that the circumferential rotational position of the cylindrical container is in a certain direction. It can be regulated to face. In addition, this cylindrical container direction regulating device can reliably achieve a desired function simply by providing one direction regulating means above the conveyor so as to be inclined with respect to the conveying direction of the conveyor. It is simple, can be manufactured at low cost, and can be easily maintained and inspected.

It can be adjusted with.

  The drive motor 8 is mounted on the upper surface of the wide portion 6a of the support frame 6 with its output shaft facing downward, and the output shaft is supported by a support piece 16 on the lower surface of the support frame 6. A pulley shaft 18 that is rotatably supported on a horizontal plane is connected by a bearing of a bearing housing 17 that is supported in this manner, and a drive pulley 19 is fixed to the pulley shaft 18. On the other hand, a support plate 21 having a bearing box 20 fixed vertically to the lower surface thereof is attached to the lower surface of the front end portion (left end portion in FIGS. 3 and 4) of the support frame 6 with bolts 21a. A pulley shaft 22 is rotatably supported in a horizontal plane on the bearing in the bearing housing 20, and a driven pulley 23 is fixed to the lower end of the pulley shaft 22. The driving pulley 19 and the driven pulley 23 are set at the same height position from the upper surface of the conveyor belt 2b of the conveyor 2, and the rotating belt 7 is wound around them in an endless shape. Circulates in a plane spaced a predetermined distance upward from the upper surface of the conveyor belt 2b of the conveyor 2.

A bolt hole 21b through which the bolt 21a of the support plate 21 is inserted is formed as a long hole along the longitudinal direction of the support frame 6 as shown in FIGS. 3 and 7, and the support plate 21 is within the range of the bolt hole 21b. Is adjusted with respect to the support frame 6 so that the tension of the rotating belt 7 can be adjusted by changing the distance between the drive pulley 19 and the driven pulley 23.
The rotating belt 7 has a protrusion (engagement) projecting a predetermined amount on the outer peripheral surface of a long belt-like belt (corrugated portion) 7a made of a material such as rubber, rubber or synthetic resin combined with a woven fabric. A plurality of joint projections) 7b are provided at predetermined intervals in the longitudinal direction of the belt-like belt 7a. For example, a well-known timing belt can be used as a transmission belt, and the tooth portion is It plays the role of the protrusion 7b.

The rear end portion of the lower surface of the support frame 6 (the downstream end portion in the transport direction a of the conveyor 2, the upper end portion in FIG. 3 and the right end portion in FIG. 8) has a position close to the base end side of the support frame 6. A pair of support members 24, 24 are vertically fixed by bolts 24a at positions close to the front end side, and the guide member 9 is provided at the lower end side of these support members 24, 24. The conveyor belt 2 is stretched from the upper surface of the conveyor belt 2b of the conveyor 2 in parallel and spaced apart by a predetermined distance.
That is, as shown in FIGS. 7 and 8, a support piece 25 is fixed to the rear side of each support member 24 (right side in FIG. 8) with bolts 25a in the vertical direction. A support shaft 26 is inserted in a direction perpendicular to the support piece 25 through a through hole 25b provided at the lower end. The support shaft 26 is fixed to the support piece 25 by a lock nut 27 and an adjustment nut 28 that are screwed to the support shaft 26 so as to sandwich the support piece 25 from the front and rear. The guide member 9 is screwed to the tip end portion of the support shaft 26 (the upstream end portion in the conveying direction of the conveyor 2, the left end portion in FIG. 8), and is fixed by a nut 26a.
The guide member 9 adjusts the amount of protrusion of the support shaft 26 forward (leftward in FIG. 8) from the support piece 25 by changing the screwing position of the lock nut 27 and the adjustment nut 28 to the support shaft 26. Thus, the position of the conveyor 2 in the transport direction a with respect to the rotating belt 7 can be adjusted. In the illustrated example, due to the shape of the cylindrical container B, the guide member 9 is positioned slightly in front of the circulating movement surface at the tip of the protrusion 7a of the rotating belt 7 (on the upstream side in the transport direction a of the conveyor 2). It is adjusted so that

On the front surface of the guide member 9 (the upstream side surface in the conveying direction of the conveyor 2, the left side surface in FIG. 8), a belt-like friction applying member (friction applying portion) 29 made of a thin rubber plate is provided in the longitudinal direction of the guide member 9. Affixed over the entire area. The friction imparting member 29 is not limited to a rubber plate, and may be a member that applies appropriate friction to the contact portion when the outer peripheral surface of the cylindrical container B comes into contact with the guide member 9. A cloth or a machined surface may be directly formed on the front surface of the guide member 9 to form a rough surface by vertical and horizontal fine grooves and unevenness.

Within this range, the movement can be adjusted up and down, and the height of the guide member 9 from the upper surface of the conveyor belt 2a of the conveyor 2 can be adjusted by this movement adjustment.

  Further, on the front side (left side in FIG. 8) of each support member 24, a support piece 30 bent in a crank shape is fixed in the vertical direction with a bolt 30a and protrudes to the front side of the support piece 30. The lower end portion extends to a position adjacent to the inside of the belt-like belt 7a that moves on the front side (upstream side of the conveyor 2) of the rotating belt 7, and the lower end portion includes the width of the rotating belt 7 and the width of the rotating belt 7. A long guide plate 31 having substantially the same width and having a smooth front surface is attached by bolts 31a. The guide plate 31 is brought close to the back surface of the belt-like belt 7a that moves on the front side of the rotating belt 7, and has a substantially full length between the drive pulley 19 and the driven pulley 23 (approximately the same length as the guide member 9). ).

  In addition, it is conveyed by the said conveyor 2 to the upper surface of the other side (lower side in FIG. 1) opposite to the installation side of the said direction control apparatus 1 in the said base 4, and the position of the circumferential direction is controlled by the direction control apparatus 1. A label affixing device 35 for affixing a label to the outer peripheral surface of the cylindrical container B is installed, and the frame 2a of the conveyor 2 is positioned on the downstream side of the direction regulating device 1 with the label affixing device 35. A label compaction device 36 that presses a label affixed to the cylindrical container B so as to be in close contact with the cylindrical container B is installed.

Next, the operation of the direction restricting device 1 for a cylindrical container configured as described above will be described with reference to FIG.
In the cylindrical container B, for example, a beverage is filled in a cylindrical container body B1 having an outer peripheral surface with a taper whose upper end is slightly larger in diameter than the lower end, and an opening at the upper end of the container body B1 is provided. A lid B2 made of aluminum is hermetically sealed, and a cap B3 made of synthetic resin is put on the lid B2. A handle (protrusion) B4 for removing the lid B2 from the container body B1 is provided at one location on the outer periphery of the lid B2 in a state of protruding in the radial direction and bent downward.

  In the direction restricting device 1, the height of the base plate 11 with respect to the support plate 10 is adjusted in advance by the adjusting bolt 12, so that the rotating belt 7 and the guide member 9 are separated from the upper surface of the conveyor belt 2 b of the conveyor 2. The height is adjusted according to the size of the cylindrical container B. Further, by adjusting the mounting angle of the support frame 6 with respect to the support plate 13 on the base plate 11 around the shaft pin 14 by the bolt hole 6a and the bolt 15, the conveyor 2 of the support frame 6 is adjusted. The inclination angle θ with respect to the transport direction a is adjusted in accordance with the diameter of the cylindrical container B, the transport speed of the conveyor 2, the moving speed of the rotating belt 7, and the like. Further, the bolt 25a and its insertion hole 25c are used to support the support member 24 of the support frame 6 with respect to the position in the height direction of the protrusion B4 of the cylindrical container B and the protruding amount in the radial direction. The height of the support piece 25 is adjusted, and the fixing position in the axial direction of the support shaft 26 with respect to the support member 24 is adjusted by the lock nut 27 and the adjustment nut 28, and the cylindrical container B of the guide member 9 is adjusted. The contact position with respect to the outer peripheral portion and the engagement state of the projection B4 of the cylindrical container B with the projection 7b of the rotating belt 7 are finely adjusted.

  When the direction regulating device 1 adjusted in this way is actuated, the conveyor 2 is actuated to move the conveying belt 2b in the conveying direction a, and the drive motor 8 of the direction regulating means 3 is activated. Thus, the rotating belt 7 is moved in the direction of the arrow b from the driven belt 23 located on the upstream side of the conveyor 2 toward the driving pulley 19 side located on the downstream side of the belt-like belt 7a on the front side. In this state, the cylindrical container B is connected to one end side on the upstream side of the conveyor 2 (FIGS. 1 and 3) by a container supply device (not shown) such as another conveyor installed in front of the conveyor 2. , In the upper end side in FIG. 9, it is placed upright on the conveyor belt 2 b, and is continuously and randomly supplied in a line without using a container alignment device.

  The cylindrical containers B supplied to the conveyor belt 2b of the conveyor 2 are successively conveyed to the front surface of the direction restricting means 3 while maintaining an upright state, and the outer peripheral portion of the container body B1 is connected to the guide member 9. When the guide member 9 is in contact with the front surface, the guide member 9 is inclined with respect to the transport direction a of the conveyor 2, so that the thrust f in the transport direction a by the transport belt 2 b is applied to the cylindrical container against the guide member 9. Since it acts on the cylindrical container B eccentrically by a distance h in a direction perpendicular to the conveying direction a of the conveyor 2 from the contact point of B, a rotational moment is generated in the cylindrical container B. Thus, the direction of the arrow b from the one end side (upstream side) of the guide member 9 toward the other end side (downstream side) while the cylindrical container B rotates in the direction of arrow c (counterclockwise) in FIG. Accordingly, the projection B4 of the cylindrical container B located at an arbitrary circumferential position rotates and moves toward the rotating belt 7 and moves along the front side of the rotating belt 7. When it faces 7a, it is hooked (engaged) with the projection 7b.

Even when the projection B4 is not engaged with the projection 7b of the rotating belt 7 in a timely manner when the cylindrical container B rotates toward the rotating belt 7 and faces the belt 7a, the rotating belt 7 has a large number of Since the protrusion 7b is provided and moves continuously, the protrusion B4 of the rotating belt 7 is rotated while the cylindrical container B rotates repeatedly and moves to the other end side (downstream side) of the conveyor 2. The protrusion 7b is securely engaged.
When the projection B4 of the cylindrical container B is engaged with the projection 7b of the rotating belt 7, the cylindrical container B is stopped from rotating and the bottom surface slides on the surface of the conveyor belt 2b of the conveyor 2, and the rotating belt 7 When the protrusion 7b of the rotating belt 7 faces the direction perpendicular to the conveying direction a of the conveyor 2 at the other end, the protrusion B4 of the cylindrical container B engages with the protrusion 7b. When the cylindrical container B is unwound, the other end of the conveyor 2 is separated from the other end of the rotating belt 7 and the guide member 9 with the protrusion B4 directed in a certain direction (inner side in the width direction of the conveyor 2). By the part on the part side, the sheet is sequentially conveyed to the downstream side in the conveyance direction a one by one.

  When the cylindrical container B is conveyed from the direction restricting means 3 to the downstream side of the conveyor 2 with the position of the protrusion B4 facing inward in the width direction of the conveyor 2, it is installed adjacent to the direction restricting means 3. In the label sticking device 35, a large number of labels R stuck along the longitudinal direction of the tape T wound around the supply reel 35a are folded back by the tape turning portion 35c in the label sticking portion 35b and taped to the take-up reel 35d. In the process of winding T, the tape T is peeled off, the glue surface is directed to the cylindrical container B side, and the roller 35e at the tip of the label attaching part 35 is opposite to the protrusion B4 of the cylindrical container B. Affixed to the outer peripheral surface. The cylindrical container B to which the label R is attached is pressed on the outer peripheral surface by the rolling belt 36a and the pressing member 36b of the rolling device 36 while being conveyed further downstream by the conveyor 2. After the label R is brought into close contact with the outer peripheral surface of the cylindrical container B, it is removed from the conveyor 2 and conveyed to the next processing step.

  As described above, in the cylindrical container direction regulating device 1 according to the embodiment, the direction regulating means 3 has the projection 7b that can be engaged with the projection B4 of the cylindrical container B spaced apart in the length direction. A plurality of endless rotating belts 7 wound around a driving pulley 19 and a driven pulley 23, a driving motor 8 for rotating the driving pulley 19 and circulatingly moving the rotating belt 7, A guide member 9 that guides the cylindrical container B in contact with the outer peripheral surface thereof, and the rotating belt 7 and the guide member 9 are respectively spaced at a predetermined distance from the upper surface of the conveyor belt of the conveyor 2 at different heights. And the end portion on the downstream side in the conveying direction a of the conveyor 2 is disposed at the same inclination angle θ with respect to the conveying direction a of the conveyor 2. B down 1 A cylindrical container B which is set at a position closer to the inner side than the end in the width direction of the conveyor 2 by a distance necessary to pass through the conveyor 2 and is conveyed by the conveyor 2 and brought into contact with the guide member 9 is When the protrusion B4 is engaged with the protrusion 7b of the rotating belt 7, it moves along the guide member 9 from the upstream position in the transport direction a of the conveyor 2 toward the downstream position while maintaining the engaged state. It is supposed to be configured.

  Therefore, according to the direction control apparatus 1 of the cylindrical container which concerns on the said embodiment, the cylindrical container B conveyed from the upstream to the downstream side at random by the conveyor 2 is guidance of the direction control means 3. Contacting the member 9 and rotating in the circumferential direction, the projection B4 is engaged with the rotating belt 7, and this engagement ensures that the circumferential rotational position of the cylindrical container B is fixed in a certain direction (inner side in the width direction of the conveyor 2). It can be regulated to face in the direction facing towards. In addition, the direction regulating device 1 for the cylindrical container B is provided with one direction regulating means 3 (a combination of the rotating belt 7 and the guide member 9) inclined above the conveyor 2 with respect to the conveying direction a of the conveyor 2. Thus, a desired function can be surely achieved, the structure is extremely simple, it can be manufactured at low cost, and maintenance and inspection can be easily performed. can do.

Moreover, according to the direction control apparatus 1 of the cylindrical container which concerns on the said embodiment, since the friction provision member 29 is provided in the surface which faces the upstream of the conveyance direction a of the conveyor 2 in the said guide member 9, a cylinder is provided. When the cylindrical container B comes into contact with the guide member 9, the circumferential rotation of the cylindrical container B is surely performed, and the protrusion B 4 is reliably directed toward the rotating belt 7, so that the protrusion 7 b of the rotating belt 7 is made to protrude from the cylindrical container B. It can be easily engaged with B4.
In addition, since the guide member 9 is provided so as to be able to move and adjust the position of the conveyor in the conveyance direction a with respect to the rotating belt 7, the guide member 9 is disposed between the cylindrical container B that contacts the guiding member 9 and the rotating belt 7. The interval can be adjusted, and the engagement state of the protrusion 7b of the rotating belt 7 with respect to the protrusion B4 of the cylindrical container B can be adjusted appropriately.

Further, since the rotating belt 7 is formed by turning over the transmission timing belt, the rotating belt 7 can be easily obtained as an off-the-shelf product, and the rotating belt 7 has flexibility, so that it is conveyed by the conveyor 2. The cylindrical container B can be smoothly and quietly moved to the downstream side while performing rotational positioning of the cylindrical container B by flexibly contacting and engaging with the projection B4 of the cylindrical container B. There is no risk of damage.
Further, since the guide plate 31 for guiding the belt-like belt 7a is provided along the back surface of the belt-like belt 7a moving on the upstream side of the conveying direction a of the conveyor 2 in the rotating belt 7, the abutment of the cylindrical container B is provided. Therefore, the rotation belt 7 can be prevented from being bent, and its protrusion 7b is firmly engaged with the protrusion B4 of the cylindrical container B so that the end of the cylindrical container B reaches the downstream end of the rotation belt 7. It can be moved while reliably maintaining the circumferential positioning state.

Further, since the moving speed of the rotating belt 7 is set to be lower than the conveying speed of the conveyor 2, when the cylindrical container B moves to the downstream end of the guide member 9, the protrusion 7 b of the rotating belt 7. The projection B4 of the cylindrical container B is quickly and smoothly detached from the cylindrical container B, thereby conveying the cylindrical container B to the downstream side of the conveyor 2 without causing the circumferential displacement of the projection B4. be able to.
Further, since the inclination angle θ of the rotating belt and the guide member 9 with respect to the conveying direction a of the conveyor 2 can be changed and adjusted via the support frame 6, the shape size of the cylindrical container B, the conveying speed of the conveyor 2, Corresponding to the moving speed or the like of the rotating belt, the moving speed of the cylindrical container B that moves downstream along the guide member 9 is appropriately adjusted, and the circumferential positioning operation of the cylindrical container B is performed. It can be performed smoothly.

  In the cylindrical container direction regulating device 1, the rotating belt 7 is provided above the guide member 9, but the upper and lower relative positions of the rotating belt 7 and the guide member 9 are different from those of the cylindrical container B. It can be changed as appropriate depending on the size, the position of the protrusion B4, and the like. Moreover, although the rotating belt 7 which provided the protrusion 7b in the strip | belt-shaped part 7a was used as said rope-like member, it can replace with this and can use what provided the protrusion in the endlessly connected wire rope or chain. . In this case, instead of the pulleys 19, 23, a rope wheel or a pocket wheel is used.

  In the direction restriction device 1 for the cylindrical container according to the first embodiment, since the height is high with respect to the diameter and the cylindrical container B having the protrusion B4 near the top is targeted, the direction restriction is performed. The means 3 is constituted by the rotating belt 7, the driving motor 8 that circulates the rotating belt 7, and the guide member 9 that guides the cylindrical container B to the downstream side by contacting the outer periphery thereof. The present invention is not limited to this. For example, like a compact case for makeup, a lid K3 is provided on a disc-like case body K1 by a hinge (projection) K2 so that it can be opened and closed. When a flat container (cylindrical container) K provided with a finger hook K4 for opening the lid is used as a target, the rotating belt 7 and the drive motor 8 can be omitted.

Next, FIGS. 10 to 13 show a cylindrical container direction regulating device 1A according to a second embodiment in which the rotating belt 7 and the drive motor 8 are omitted.
In the cylindrical container direction regulating apparatus 1A according to this embodiment, an engagement guide member 9A instead of the guide member 9 is attached to the support shaft 26 in the same manner as the guide member 9, and the conveying direction of the conveyor 2 is set. It is inclined with respect to a with an inclination angle θ. The engagement guide member 9A has an L-shaped cross section, and the horizontal portion 9a protruding forward is located at a height position closer to the upper surface of the conveyor belt 2b of the conveyor 2 than the guide member 9. The outer peripheral portion of the cylindrical container K conveyed by the conveyor 2 and the protrusion K2 are in contact with and engaged with the front end surface 9b of the horizontal portion 9a. The friction applying member (friction applying portion) 29 is provided on the front end surface 9b of the horizontal portion 9a.

  Further, the end of the engagement guide member 9A on the downstream side in the transport direction a of the conveyor 2 is supported by a pin 40 and horizontally swiveled by an actuator (swivel drive means) 41 such as a cylinder or an electromagnetic actuator. A turning plate (turning guide member) 42 is provided. The swivel plate 42 has a guide surface 42a with which the cylindrical container K comes into contact engagement with the front end surface 9b of the engagement guide member 9A facing the upstream side in the transport direction a of the conveyor 2 along the same plane. The first position p1 extended outward in the width direction of 2 and the guide surface 42a facing outward in the width direction of the conveyor 2 from the end of the engagement guide member 9A to the downstream side in the transport direction a of the conveyor 2 It is designed to turn horizontally with respect to the extended second position p2.

The frame 2a of the conveyor 2 is provided with an optical sensor 43 composed of a light emitter 43a and a light receiver 43b so as to sandwich a passage for a cylindrical container K moving on the conveyor 2 from the upstream side to the downstream side. When the outer peripheral portion of the cylindrical container K and the projection K2 are brought into contact with the revolving plate 42 at the first position p1 by moving downstream along the engagement guide member 9A, the light emitter 43a Is blocked by the projection K2 of the cylindrical container K, the rod of the actuator 41 is contracted based on the signal from the light receiver 43b thereby, and the swivel plate 42 is swung to the second position p2, When the cylindrical container K passes the position of the optical sensor 43, the rod of the actuator da 41 extends based on the signal from the light receiver 43b that receives and transmits the light from the light emitter 43a. Actuated, the swing plate 42 is adapted to be pivoted to the first position p1.
Since the other configuration is the same as that of the cylindrical container direction regulating device 1 according to the first embodiment, the same components are denoted by the same reference numerals, and description thereof is omitted.

  In the cylindrical container direction regulating apparatus 1A according to the second embodiment, as shown in FIG. 13, the conveyor 2 is operated, and one end side on the upstream side of the conveyor 2 (the upper end side in FIG. 13). When the cylindrical containers K are continuously and randomly supplied on the transport belt 2a at the same time, the cylindrical containers K are sequentially moved to the direction regulating means 3 as the transport belt 2b moves in the transport direction a. Is conveyed to the front surface of the engagement guide member 9A, and the outer peripheral portion of the container body K1 is brought into contact with the distal end surface 9b of the engagement guide member 9A. Then, because the engagement guide member 9A is inclined with respect to the conveying direction a of the conveyor 2, the cylindrical shape is the same as in the case of the direction regulating device 1 for the cylindrical container according to the first embodiment. A rotational moment is generated in the container K, whereby the cylindrical container K moves from one end side to the other end side of the engagement guide member 9A while rotating in the direction of arrow c (counterclockwise) in FIG. To do. Along with this, the protrusion K2 of the cylindrical container K that was at an arbitrary circumferential position rotates and moves toward the distal end surface 9b side of the engagement guide member 9A, and the corner of the protrusion K2 is the angle of the engagement guide member 9A. When it comes into contact with the front end surface 9a, the cylindrical container comes into contact with and engages with the engagement guide member at two positions, the corner of the projection K2 of the cylindrical container K and the outer peripheral portion of the cylindrical container K adjacent to the projection K2. The rotation is stopped. The cylindrical container K, which has been brought into contact with the engagement guide member 9A and stopped rotating, keeps its posture and slides on the upper surface of the conveyor belt 2b of the conveyor 2 along the engagement guide member 9A. Move to the end of

  Then, the cylindrical container K moved to the downstream end of the engagement guide member 9A further moves to the guide plate 42 located at the first position p1, and reaches the distal end surface 9b of the engagement guide member 9A. Contact and engagement with the guide surface 42a, which is flush with each other, without changing the posture. At that time, since the light emitted from the light emitter 43a of the optical sensor 43 is blocked by the protrusion K2 of the cylindrical container K, the light receiver 43b detects this, and the actuator 41 is operated. The guide plate 42 is quickly turned to the second position p2. This opens a passage through which the cylindrical container K moves downstream in the conveying direction a of the conveyor 2, so that the cylindrical container K directs the protrusion K2 in a certain direction (conveying direction a of the conveyor 2). In this state, the engagement guide member 9 </ b> A is separated from the downstream end of the engagement guide member 9 </ b> A and is conveyed one by one by the portion on the other end side of the conveyor 2 to the downstream in the conveyance direction a. Each time one of the cylindrical containers K leaves the downstream end of the engagement guide member 9A and moves to the downstream side in the transport direction a of the conveyor 2, the optical sensor 43 detects it and the actuator 41 Is operated to return the guide plate 42 to the first position p1.

As described above, when the cylindrical container K moves away from the engagement guide member 9A and moves to the downstream side in the transport direction a of the conveyor 2, the cylindrical container K is once contacted and engaged with the swivel plate 42, When the turning plate 42 is turned from the first position p1 to the second position p2 by the actuator 41, the cylindrical container K positioned in the circumferential direction by the engagement guide member 9A turns around the back side of the engagement guide member 9A. Therefore, the cylindrical container K can be transported to the downstream side in the transport direction a of the conveyor 2 without causing a displacement of the protrusion K2 positioned in the circumferential direction.
In addition, by changing and adjusting the inclination angle θ of the engagement guide member 9A with respect to the conveyance direction a of the conveyor 2 via the support frame 6, the shape and size of the cylindrical container B, the conveyance speed of the conveyor 2 and the like can be accommodated. Thus, it is possible to appropriately adjust the moving speed of the cylindrical containers K that move to the downstream side along the guide member 9 so that the circumferential positioning operation of the cylindrical containers K can be performed smoothly.
According to the cylindrical container direction regulating apparatus 1A according to the second embodiment, the same effects as the cylindrical container direction regulating apparatus 1 according to the first embodiment are achieved, and the Unlike the direction restriction device 1 for the cylindrical container according to the first embodiment, the direction restriction means 3 does not include the rotating belt 7 and the drive motor 8 that circulates the rotation belt 7, so that the configuration is simplified accordingly. Easy to implement.

  In the cylindrical container direction regulating device 1, 1A according to each of the embodiments, the cylindrical container B and the disk-shaped container K provided with the protrusions B4 and K2 on the outer periphery are processed.
