Description

  The present invention relates to a transfer device that is arranged on a conveyor line and carries out or carries in articles from the conveyor line.

  In product assembly lines and article delivery areas, conveyor lines are often used for conveying articles. For example, a large number of conveyor lines are installed vertically and horizontally in a delivery area, and a transfer device is arranged at a position where the conveyor lines intersect. Then, by operating the transfer device, the article is carried out from the original conveyor line, transferred to another conveyor line, and conveyed to a desired place.

Here, the transfer device generally has an article transport unit and an elevating unit, and normally the top surface of the article transport unit is placed on the vertical conveyor line so as not to interfere with the transport of articles on the conveyor line. It is stored below the transport surface. Then, the destination of the article flowing through the conveyor line is determined by a sensor or the like, and if the article is a predetermined article, the article is stopped on the transfer device by a stopper. Next, the lifting / lowering unit is operated to raise the article conveying unit above the conveying surface of the vertical conveyor line, thereby scooping up the article. And an article conveyance part is operated and articles | goods are sent out to another conveyor.
The specific configuration of the transfer device is disclosed in Patent Documents 1 and 2.

In the transfer apparatus disclosed in Patent Documents 1 and 2, an article conveying unit using a belt is employed. That is, in the transfer apparatus disclosed in Patent Document 1, two belts are suspended in parallel, and the articles are scooped up by the two belts. The two belts travel in the same direction, and the articles are discharged from the main conveyor line in a perpendicular direction.
The same applies to Patent Document 2. Five belts are suspended in parallel, the five belts travel in the same direction, and the articles are discharged from the main conveyor line in a perpendicular direction.

In the transfer apparatus disclosed in Patent Literatures 1 and 2, the article is scooped up by the belt, and the article is moved in the right angle direction from the conveyor line in the same posture.
Therefore, the top surface of the article discharged by the transfer device of the prior art changes.
For example, it is assumed that the article is a legislative body and has four surfaces A, B, C, and D counterclockwise in addition to the upper and lower surfaces. The conveyor line is conveyed with the A surface as the leading surface, the C surface as the back surface, and the B and D surfaces as the side surfaces. When this article is discharged to the branch line extending in the vertical direction by the transfer device, the side surface is B. It will be discharged to the branch line with the surface or C surface as the head. After that, the article is conveyed on the branch line side conveyor line with the B or D surface, which was the side surface first, as the leading surface.

Here, in the case where the articles are finely sorted for each delivery destination like a large-scale delivery center, a plurality of conveyor lines are interlaced, and a transfer device is installed at each branch point. On the other hand, a barcode or the like indicating a delivery destination is provided on the side surface of the article.
Then, the destination of the article is detected by a bar code reader provided on the conveyor line, and the transfer device is made to function according to this signal to discharge the article to the branch line side, or the transfer device is kept stopped. Move the item straight.

However, in the prior art, as described above, the top surface of the article discharged by the transfer device changes. For this reason, the surface to which the barcode or the like is attached moves, and it may be difficult to read the barcode or the like.
Then, this invention makes it a subject to develop the transfer apparatus which can discharge | emit and carry in articles | goods from a conveyor line etc., without changing the attitude | position with respect to the advancing direction of articles | goods.

Invention of Claim 1 for solving an above-described subject is installed in a roller conveyor line, and the raising / lowering part which raises / lowers the article conveyance part which mounts and moves an article and the said article conveyance part is provided. wherein the article conveyor portion is for urging passage for biasing the article in contact with the placed article in one direction is provided a plurality of rows, wherein the biasing path from between the roller conveyor roller A main energizing path that has a width that allows entry and exit, and that the conveying direction of the roller conveyor and the conveying direction of the article are different, and that functions so that the article moves in a certain direction, and the article is a main energizing path Has an auxiliary biasing path that functions to move in the opposite direction, and is capable of simultaneously functioning the main biasing path and the auxiliary biasing path.

  In the transfer device of the present invention, a plurality of urging paths are provided. The energizing path includes a main energizing path that functions so that the article moves in a certain direction, and an article that functions so as to move in a direction opposite to the main energizing path or from the main energizing path. There is also an auxiliary biasing path (including one that is stopped) that moves the article slowly. For this reason, when the article is placed on the article transport section of the transfer device and the main biasing path and the auxiliary biasing path are operated, a force for rotating the article is generated due to the difference in the traveling direction and the speed of the both. Therefore, the article placed on the transfer device is discharged to a branch line or the like while changing its posture (direction). The same applies to the case where an article is carried from the branch line side to the main line side, and the article is introduced while changing its posture (orientation).

In addition, the transfer device of the present invention includes an elevating unit, and the article conveying unit can be raised and lowered by the elevating unit. Further, since the urging path has a width that allows entry and exit between the rollers of the roller conveyor, the urging path enters and exits from the roller conveyor by raising and lowering the article conveying unit.

In the invention according to claim 2, the urging path has a belt for urging the article, both of the belts are driven by a common power source, and the main urging path and the auxiliary urging path have belt running paths. The transfer device according to claim 1, wherein the transfer device is different.

In the transfer device of the present invention, the biasing path includes a belt, and the article is placed on the belt. The article is urged by the running of the belt.
In the transfer device of the present invention, since the belts constituting each urging path are all driven by a common power source, the number of parts is small. Further, in the present invention, the auxiliary biasing path makes the traveling direction different by making the traveling path of the belt different from the main biasing path. Therefore, the transfer device according to the present invention has a smaller number of parts and a simple structure.

The invention according to claim 3, the sum of the urging force for all of the articles of primary biasing path, or claim 1 and the sum of the biasing force to an article of any auxiliary biasing circuit, characterized in that different 2. The transfer apparatus according to 2 .

In the transfer device of the present invention, the total urging force for the articles on the main urging path and the total urging force for the articles on all the auxiliary urging paths are unbalanced. Therefore, the article placed on the transfer device advances in either direction while changing the posture. That is, if the sum of the urging forces for the articles on the main urging path and the sum of the urging forces for the articles on all the auxiliary urging paths are the same, the article rotates on the spot. For example, the driving directions of the main biasing path and the auxiliary biasing path are opposite, but the number of strips of the main biasing path and the auxiliary biasing path are the same, and the width and material of the belt and the like are the same, and further the traveling If the speed is also the same, the article placed on the article transport section of the transfer device only rotates on the spot.
On the other hand, in the transfer device of the present invention, the sum of the urging forces for the articles of all the main urging paths is different from the sum of the urging forces for the articles of all the auxiliary urging paths. The article receives a stronger force from the biasing path, and the article is pulled by one of the biasing paths and moves in that direction. That is, the article advances in one direction while rotating.

Note the total biasing force to all of the articles of primary biasing path, as a measure to provide a difference in the sum of the biasing force to an article of any auxiliary biasing path, Omozuke as the invention described in claim 4 It is conceivable to make a difference between the number of lanes and the number of auxiliary urging channels.

  Other measures include changing the contact area of the main urging path with the bottom of the article and the contact area of the auxiliary urging path to change the area in contact with the article, or the material of the members constituting the main urging path In this case, it is conceivable to make a difference in the coefficient of friction by changing the material of the members constituting the auxiliary biasing path.

The invention according to claim 5 is the transfer device according to any one of claims 1 to 4 , wherein both the main biasing path and the auxiliary biasing path are arranged in a group.

  In the transfer device of the present invention, the main urging path and the auxiliary urging path are both arranged in a group, so that it is easy to give a moment to the placed article. Therefore, in the transfer device of the present invention, the placed article rotates smoothly and changes its posture.

  The transfer device of the present invention has an effect that the posture of an article can be changed when the article is discharged or carried. Therefore, the posture with respect to the traveling direction of the article can be kept constant.

FIG. 7 is an exploded perspective view showing a connection structure between plate members of the transfer apparatus shown in FIG.
Each of the urging paths 5a to 5d has one plate-like member 7, and eight pulleys 10 to 17 are supported in a cantilevered manner as shown in FIGS.
All of the plate-like members 7 have the same shape and have a substantially band shape. A protruding portion 20 is provided at the lower center of the plate-like member 7. The protrusion 20 is provided with an arcuate cutout 21.

As described above, eight pulleys 10 to 17 are cantilevered on the plate-like member 7. These pulleys 10 to 17 are all free to rotate. The arrangement of the pulleys 10 to 17 is as shown in FIGS. 5 and 6, and six pulleys 10 to 15 are provided in a row on the upper surface side. The remaining two pulleys 17 and 18 are provided in the vicinity of the protruding portion 20 of the plate-like member 7.
The perspective view of FIG. 5 shows the main urging paths 5a, 5b, and 5c, but the main urging paths 5a, 5b and the main urging path 5c have pulleys with respect to the plate member 7. The mounting side is the opposite side. Therefore, each pulley of the main urging path 5c is attached to the other side of the page with respect to the plate-like member 7 shown in FIG.

As shown in FIGS. 1 and 7, the shafts 23 and 25 are inserted into the plate-like member 7, and the four plate-like members are bound and integrated in a state of being sandwiched between the outer elevating plates 8 and 9. ing. In this embodiment, the direction of the plate member 7 is arranged with the pulley mounting side facing inward as shown in FIGS.

In addition, it is possible to change the space | interval of the plate-shaped members 7 by changing the length of the tubular body 19, and adjust the space | interval of the energizing paths 5a-5d according to the conveyor which installs the transfer apparatus 1. FIG. be able to.

  Further, a tube 18 is disposed between the plate-like member 7 of the auxiliary biasing path 5d and the lifting plate 8 of the shafts 23 and 25. That is, the tubular body 18 is inserted into the shaft 23 or 25, the plate-like member 7 of the auxiliary biasing path 5d is in contact with one end, and the elevating plate 8 is in contact with the other end. The interval between them is kept at a predetermined distance. A tubular body 22 similar to the tubular body 18 is also disposed between the plate-like member 7 of the main urging path 5 a and the lifting plate 9 of the shafts 23 and 25. Screws are provided at both ends of the shafts 23 and 25, and the main urging paths 5a to 5a are arranged with a predetermined interval between the elevating plates 8 and 9 by screwing the nuts 24 into the screw parts. 5c and auxiliary biasing path 5d are fixed.

A roller 26 with a built-in conveying motor is inserted into the notch 21 of the plate-like member 7.
FIG. 8 is a cross-sectional view of the transport motor built-in roller.
The transport motor built-in roller 26 employed in the present embodiment will be described. The transport motor built-in roller 26 includes a motor 30 and a reduction gear 31 including a planetary gear train in a cylindrical body 28 as shown in FIG. It is a thing.

  In the transport motor built-in roller 26, neither of the fixed shafts 33 and 34 protruding from the cylindrical body 28 (roller body) rotates at all. When the motor 30 is rotated, the rotational force of the motor 30 is transmitted to the roller body 28 via the speed reducer 31. As a result, when the motor 30 is rotated, the outer cylindrical body 28 is decelerated and rotated.

  A belt 37 is suspended between pulleys 10 to 17 provided on the plate-like member 7 and a roller body 28 of the roller 26 with a built-in motor for conveyance. In the present embodiment, a toothed belt is adopted as the belt 37. The reason why the toothed belt is used is that the tensile strength is high and the flexibility is high, but a flat belt may be used instead of the toothed belt.

Here, the suspension path of the belt 37 is different between the main urging paths 5a to 5c and the auxiliary urging path 5d.
That is, the suspension path of the belt 37 in the main urging paths 5a to 5c is as shown in FIG. 5, and the belt 37 is suspended from each driven pulley in contact with the upper side of the transport motor built-in roller 26 as a drive source . . On the other hand, in the auxiliary biasing path 5d, as shown in FIG. 6, it is suspended from each driven pulley in contact with the lower side of the transport motor built-in roller 26 as a drive source .
Therefore, the traveling direction of the pulley 35 is opposite in the main biasing paths 5a to 5c and the auxiliary biasing path 5d.

For example, when the transport motor built-in roller 26 as a driving source rotates counterclockwise as shown in FIG. 5, the belt 37 of the main urging paths 5 a to 5 C travels in the order of the pulleys 10, 11, 12, 13, 14, 15. To do. That is, the vehicle travels from the right to the left as shown by the arrows in the drawing.
On the other hand, in the auxiliary biasing path 5d, the belt 37 travels from the right to the left in the drawing as indicated by the arrow in the drawing. That is, since the driving source of the main urging paths 5a to 5c and the auxiliary urging path 5d are both driven by the transport motor built-in roller 26 as a common power source, the driving source rotates in the same direction, but the belt 37 Since the suspension path is different, the belt 37 of the auxiliary biasing path 5d travels in the order of the pulleys 15, 14, 13, 12, 11, and 10. That is, the vehicle travels from the left to the right as shown by the arrows in the drawing.

In the present embodiment, as described above, the eight pulleys 10 to 17 are attached to the plate-like member 7, and six of these pulleys 10 to 15 are provided in a row at the upper position. Among the pulleys 10 to 15, the pulleys 10, 11, 13, 14, and 15 are engaged with the belt 37 on the upper side of the pulleys 10 to 15. The belt 37 is suspended. The reason for this is to apply an appropriate tension to the belt 37. Therefore, if there is another tension applying means, the belt 37 may be suspended above all the pulleys 10 to 17 on the upper side.
Further, in this embodiment, eight pulleys 10 to 17 are provided in a row at the upper position, and only one of the pulleys 12 has the belt 37 suspended on the lower side of the pulley 12. In the case where the belts 37 are arranged, the belt 37 may be engaged with lower portions of two or more pulleys.

In order to apply tension, it is desirable that the position of the pulley with which the belt 37 is engaged is varied.
For example, among the urging paths 5a to 5d, the urging path 5a engages the belt 37 under the pulley 11, and the adjacent urging path 5b engages the belt 37 under the pulley 12. It is recommended not to align the part where the belt 37 does not appear on the upper side.

Next, the elevating unit 3 will be described.
FIG. 9 is a perspective view of the end of the lifting tool of the present invention. FIG. 10 is a cross-sectional view of the lifting tool of the present invention.
The elevating unit 3 is composed of two elevating motor built-in rollers 40 and 41.

As with the known motor built-in rollers, the lifting motor built-in rollers 40 and 41 have a motor 51 and a speed reducer 52 built in the cylindrical body 50, and the rotation of the motor 51 is decelerated and transmitted to the cylindrical body 50. is there. For the lifting motor built-in rollers 40 and 41, neither of the fixed shafts 55 and 56 protruding from the cylindrical body 50 rotate at all. When the motor 51 is rotated, the rotational force of the motor 51 is transmitted to the cylindrical body 50 through the speed reducer 52. As a result, when the motor 51 is rotated, the outer cylindrical body 50 is decelerated and rotated.
In the lifting motor built-in rollers 40 and 41, a reduction gear having a standard reduction ratio is employed. Further, in the lifting motor built-in rollers 40 and 41, a resistance member is provided inside in order to stabilize the lifting unit 3. Further, the lifting motor built-in rollers 40 and 41 are special in the shape of the lid members 70 and 71.

  That is, the cylindrical body 50 is a member that is open at both ends, and both ends thereof are sealed by the lid members 70 and 71. Bearings 72 and 73 are interposed between the lid members 70 and 71 and the fixed shafts 55 and 56. The lid members 70 and 71 rotate with the cylindrical body 50, and the fixed shafts 55 and 56 do not rotate. .

  The shapes of the lid members 70 and 71 are unique and have an eccentric structure as shown in FIG. That is, the lid members 70 and 71 have a portion that fits with the cylindrical body 50 and a portion that protrudes from the cylindrical body 50, and the protruding portion has a circular center that is eccentric with respect to the holes of the fixed shafts 55 and 56. A protrusion (eccentric part) 75 is provided.

  A ring 76 is rotatably mounted on the circular protrusion 75 via a bearing. As shown in FIGS. 1 and 9, the ring 76 is provided with a connecting portion 77.

The fixed shafts 55 and 56 of the lifting motor built-in rollers 40 and 41 are attached to a base (not shown). Further, the connecting portion 77 of the ring 76 is connected to the lifting plates 8 and 9 of the article transport unit 2 described above.
The two lift motor built-in rollers 40 and 41 rotate synchronously.

  As shown in FIGS. 2, 3, and 4, the transfer device 1 according to the present embodiment is disposed and used inside a longitudinally-feed conveyor unit 83. As shown by a two-dot chain line in FIG. 4, the conveyor unit 83 is a unit in which a large number of rollers including a motor built-in roller are arranged in a single frame. And the conveyor unit 83 has a part where the distance between the rollers is set wide at four places, and a row of pulleys of the transfer device 1 is arranged in the part.

Next, the operation of the transfer device 1 according to the present embodiment will be described by taking as an example the case of sending articles from the main conveyor line to the sub-conveyor line side of the tributary.
FIGS. 11-14 is explanatory drawing which shows a series of operation | movement of the transfer apparatus at the time of discharging | emitting an article | item from the branch point of a main conveyor line and a sub conveyor line.

The main conveyor line is a line in which roller conveyor units are arranged in the order of an upstream conveyor unit 84, a conveyor unit 83, and a downstream conveyor unit 85 as shown in FIGS. In the main conveyor line, the article 87 is conveyed in the order of the upstream conveyor unit 84, the conveyor unit 83, and the downstream conveyor unit 85.
A sub conveyor line 86 is connected in a direction perpendicular to the main conveyor line. More specifically, a sub-conveyor line 86 is connected to the side surface portion of the conveyor unit 83.

And the transfer apparatus 1 is provided in the conveyor unit 83 of a branch part as mentioned above. The attitude of the conveyor unit 83 is such that the main urging paths 5 a to 5 c are on the downstream conveyor unit 85 side and the auxiliary urging path 5 d is on the upstream conveyor unit 84.
The main urging paths 5a to 5c arranged on the downstream side travel the belt 37 toward the discharge side (that is, the auxiliary conveyor line 86 side), and the auxiliary urging path 5d has the belt 37 in the opposite direction. To run.

In the transfer device 1, the circular protrusions (eccentric portions) 75 of the lifting motor built-in rollers 40 and 41 are normally stopped at a lower position.
Accordingly, the article transport unit 2 of the transfer device 1 is in a lowered state, and the pulleys 10 to 15 and the belt 37 of the article transport unit 2 are sunk between the rollers of the conveyor unit 83. Therefore, the articles conveyed by the main conveyor line are smoothly conveyed downstream without hitting the article conveying unit 2.

When a sensor (not shown) detects that a specific article has been conveyed on the conveyor unit 83, the article 87 is stopped at a position directly above the transfer device 1. Next, the lifting motor built-in rollers 40 and 41 are rotated by about 180 ° in one direction, and the eccentric members 75 of the lid members 70 and 71 are moved up and down at a position directly above the centers of the lifting motor built-in rollers 40 and 41. The motor built-in rollers 40 and 41 are stopped.
The lift motor built-in roller 40 is provided with a proximity sensor (not shown). The proximity sensor detects that the rotation angle of the cylindrical body 50 serving as the roller body has reached a fixed position, and the lift motor built-in roller 40, 41 stops.
Ascending / descending motor built-in rollers 40 and 41 rotate about 180 °, and the eccentric portions 75 of the lid members 70 and 71 are positioned directly above the centers of the ascending / descending motor built-in rollers 40 and 41. , 41 is raised, the article conveying unit 2 of the transfer device 1 is raised, and the back surface of the belt 37 protrudes above the uppermost part of the rollers of the conveyor unit 83.

Then, the article 87 is scooped up from below by the article transport unit 2 of the transfer device 1 and is separated from the rollers of the conveyor unit 83.
Next, the transport motor built-in roller 26 is rotated. Then, the belt 37 suspended on the transport motor built-in roller 26 travels, and the article moves and is carried out of the conveyor unit 83.

Here, in the transfer device 1 of the present embodiment, since the traveling direction of the belt 37 is opposite between the main urging paths 5a to 5c and the auxiliary urging path 5d, the articles are conveyed from the main conveyor line to the sub conveyor line 86. Change posture when
That is, immediately after the article transport unit 2 is raised and the article 87 is placed on each of the main urging paths 5a to 5c, it is as shown in FIG. 11, and the article 87 is in a posture when traveling on the main conveyor line. Keep.
Specifically, the exemplary article 87 is a legislative body and has four surfaces A, B, C, and D. In the present embodiment, articles are conveyed on the main conveyor line with the A side as the top surface, the C surface as the back surface, and the B and D surfaces as the side surfaces. Therefore, immediately after the article 87 is stopped at a position directly above the transfer device 1, the article transport unit 2 is raised, and the article 87 is placed on each of the urging paths 5 a to 5 d, the posture of the article 87 is 11 is a state in which the A surface faces the downstream conveyor unit 85 side.

Next, when the conveyance motor built-in roller 26 is rotated, the belt of each urging path travels as indicated by an arrow in FIG.
That is, the main urging paths 5a to 5c arranged on the downstream side travel along the belt 37 toward the auxiliary conveyor line 86, and the belt 37 of the auxiliary urging path 5d arranged on the upstream side is reversed. Travel toward the main conveyor line.

Here, there are three main urging paths 5a to 5c for running the belt 37 toward the sub-conveyor line 86 side, and one auxiliary urging path 5d for running the belt 37 toward the main conveyor line side. The sum of the urging forces of all the main urging passages 5a to 5c on the article 87 is larger than the sum of the urging forces of all the auxiliary urging passages 5d on the article. Therefore, the article is dragged by the force from the main urging paths 5a to 5c, and moves toward the sub-conveyer line 86 as a whole.
However, since the belt 37 of the auxiliary biasing path 5d arranged on the most upstream side travels in the opposite direction to the other belts 37, the article 87 is rotated by receiving a moment by the belt 37 of the auxiliary biasing path 5d. The In particular, in the present embodiment, the auxiliary biasing path 5d is located at the outermost position with respect to the center of the article, so that the belt 37 contacts at a position far from the center of the article 87. Therefore, the article 87 receives the rotational force efficiently from the auxiliary biasing path 5d.

Therefore, as shown in FIGS. 12 and 13, the article 87 moves toward the sub-conveyer line 86 as a whole, but rotates in the moving process and changes its posture. Finally, the A-side is transferred to the sub-conveyer line 86 along the conveying direction of the sub-conveyor line 86.
Thereafter, the article 87 is conveyed on the sub-conveyer line 86 with the A side as the head.

  When the article 87 is moved and unloaded from the conveyor line 83, the lifting motor built-in rollers 40 and 41 are further rotated in the same direction. Then, as first, the circular protrusions (eccentric portions) 75 of the lifting motor built-in rollers 40 and 41 are stopped at a lower position. As a result, the article transport unit 2 descends and sinks into the conveyor line 83.

  In the embodiment described above, an example in which the engagement position between the driving conveyance motor built-in roller 26 and the belt 37 is changed as a measure for changing the traveling direction of the main urging paths 5a to 5c and the auxiliary urging path 5d. 15 and 16, for example, as shown in FIGS. 15 and 16, power is transmitted from the conveyance motor built-in roller 26 to the pulley 12 by the belt, and at this time, one of the main urging paths 5 a to 5 c and the auxiliary urging path 5 d is connected. The same effect can be expected by adopting a normal suspension system and using the other as a so-called X-hang. Moreover, you may transmit motive power with a gearwheel.

Further, the main biasing paths 5a to 5c and the auxiliary biasing path 5d may be driven by separate motors.
In the above-described embodiment, the belt is used as the main component of the main urging paths 5a to 5c and the article is placed on the belt. However, a roller may be used instead of the belt.

  In the above-described embodiment, the main urging paths 5a to 5c are three and the auxiliary urging path 5d is one, but the number of the main urging paths and the auxiliary urging paths is arbitrary.

  In the above-described embodiment, the main urging paths 5a to 5c and the auxiliary urging path 5d are run in the opposite directions, but the article 87 can also be removed by stopping one of the urging paths or slowing down the speed. Can be rotated. In short, the main biasing path and the auxiliary biasing path may be operated so as to cause a speed difference in the part of the article 87.
