BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle holder used for carrying out a predetermined treatment on a bottle while transporting the bottle, and more specifically, it is suitable for handling a bottle which is thin and easily deformed. It relates to a bottle holder used for.

[0002]

2. Description of the Related Art Resin bottles are widely used for filling liquids. The so-called bottling step of filling the bottle with the liquid includes, in addition to the step of filling the liquid, a step of tightening a cap on the bottle filled with the liquid, a step of attaching a label to the bottle, a step of printing on the bottle, and the like. ing. Further, in the bottling process, the bottle is conveyed while being stored in the bottle holder so as not to damage the bottle. Further, centering and positioning of the bottle are important in order to smoothly carry out each process. As such a technique, for example, Japanese Patent Application No. 1-58
There is a self-aligning container holder proposed in Japanese Patent No. 498.

The self-centering type container holder described above includes a holder main body for accommodating a bottle, a pair of holding plate holders movably arranged to hold the bottle in the holder main body, and each holding plate is biased. And an elastic member that operates. Therefore, when the bottle is held by this self-aligning container holder, the bottle is stored between the pair of holding plates urged by the elastic member, and the bottle is elastically held and held by the pair of holding plates. I try to align the bottle.

[0004]

However, in the case of the conventional bottle holder, there is an advantage that each bottle can be elastically pinched by the pair of pinching plates even if the shape of the bottle is slightly different, while the elastic member is used. Since the bottle is clamped by a pair of clamping plates that obtains the urging force of, when the bottle is molded with a thin resin, the bottle is crushed to some extent by the clamping force of the clamping plate and shaped. However, there was a problem that it could not be accurately bottled. Also, when such a holder is used, when the bottle is taken out of the holder in the labeling process and the printing process, it is necessary to use other means for centering and alignment each time, and at the time of bottling. There was a problem that an alignment means other than the above must be prepared.

Therefore, an object of the present invention is to support a thin-walled, easily deformable bottle without deforming the bottle, and to easily and accurately perform centering during a series of steps such as bottling, labeling and printing. It is to provide a bottle holder that can be used for.

[0006]

A bottle holder according to claim 1 of the present invention is a bottle holder used when carrying out a predetermined process on a bottle while transporting the bottle,
A holder main body for accommodating the bottle, and a support member mounted on the bottom surface of the holder main body to support the bottle so that the bottle can be moved up and down, and the support member is fitted with a recess formed on the bottom surface of the bottle. A pair of holding claws are provided movably, and an elastic member that elastically widens the distance between the holding claws is interposed between the holding claws, and a first permanent magnet that sandwiches each holding claw with the elastic member is provided. The holder main body is provided with second permanent magnets that generate a repulsive force between the holder main body and the first permanent magnets provided on the bottom surface of the holder main body. The member can be moved up and down through an opening formed on the bottom surface.

The bottle holder according to a second aspect of the present invention is the bottle holder according to the first aspect of the present invention, in which the holder body is provided with a guide member for vertically guiding the support member.

[0008]

In the bottle holder according to the first aspect of the present invention, when the support member is placed in the holder body, the first permanent magnet in the support member is disposed in the holder body.
Receiving the repulsive force by the permanent magnet, the distance between the pair of holding claws is narrowed against the elastic force of the elastic member. At this time, the bottle is housed in the bottle holder, and the holding claw is fitted into the concave portion on the bottom surface of the bottle, so that the bottle itself is centered in the holder body without receiving an external force. Further, in a process such as labeling, when the support member is lifted from the bottom surface of the holder main body through the opening in the bottom surface of the bottle main body, the repulsive force between the first permanent magnet and the second permanent magnet disappears and the pair of holding claws are removed. The elastic member obtains elasticity by the elastic member to widen the space, and the space is brought into close contact with the concave portion on the bottom surface of the bottle, so that the bottle can be supported above the bottle holder while being centered, and it is not necessary to perform centering again.

Further, in the bottle holder according to claim 2 of the present invention, in the invention according to claim 1, when the bottle is lifted from within the holder body, the centered bottle is used as a guide member together with a support member. Therefore, it is possible to lift accurately and stably.

A coil spring 7 is interposed between them as an elastic member, and the coil spring 7 is configured to give elastic force to each of the holding claws 6, 6. Further, in the space 4B of the support member 4, the first permanent magnets 8, 8 sandwiching the horizontal base portions 6B, 6B with the coil spring 7 are housed. On the other hand, the first permanent magnets 8, 8 are provided at the lower end of the straight body portion 2C of the holder body 2.
The second permanent magnets 9 and 9 are arranged at the portions facing each other. Further, the first permanent magnet 8 and the second permanent magnet 9 are
The same magnetic poles (for example, N poles) are arranged so as to face each other, and a repulsive force is generated between the first and second permanent magnets 8 and 9. Moreover, this repulsive force is set to be larger than the biasing force of the holding claw 6 by the spring 7. Therefore, the support member 4 is attached to the bottom surface portion 2.
In a state of being placed on A, the holding claws 6, 6 of the holding claws 6, 6A, 6
The interval A is most tight as shown in FIG. 1 (b), the support member 4 is lifted horizontally according to the guide members 5 and 5, and the first permanent magnets 8 and 8 are separated from the second permanent magnets 9 and 9. At times, the spring 7 applies an urging force to both the holding claws 6, 6 so that the distance between the claw portions 6A, 6A is widened.

On the other hand, as shown in FIG.
The concave portion 3B is formed in an arc shape as described above, and the bottom surface portion of the concave portion 3B is formed with a tapered surface 3C which gradually becomes deeper in the counterclockwise direction from its end portion to a substantially middle portion. A flat surface 3D is formed continuously with the tapered surface. Then, the claw portion 6A of the holding claw 6 is configured to fit on the flat surface 3D. In addition, in FIG. 2, 3E is a nozzle part. Also, the concave portion 3B of the bottle 3
As shown in FIG. 3, it is also possible to adopt a mode in which the bottom surface portion does not have the tapered surface 3C but only a flat surface.

Next, the operation of the bottle holder 1 according to this embodiment will be described with reference to FIGS. 4 and 5 based on the operation of the bottle holder 1 in the bottle arranging process by the rotary directional aligning device. The bottle holder 1 flows through the line in a state where the axis of the bottle holder 1 flowing in the alignment step and the axis of the bottle chuck 11 of the aligning device and the bottle chuck holder 12 supporting the same are surely aligned. When the bottle 3 is dropped into the bottle holder 1 that flows through this alignment process, the bottle 3 is not centered with respect to the bottle holder 1 at this point, so that the holding claws 6 and 6 are locked as shown in FIG. The claws 6A, 6A do not fit into the recessed portion 3B of the bottle 3 but abut on the bottom surface 3A, and the bottle 3 floats from the support member 4 in the holder body 2 and is in an unstable state.

In this state, when the bottle holder 1 gradually flows to the downstream side, the cam follower 13 of the bottle chuck holder 12 follows the downward slope of the cam rail 14 during that time.
(B), it gradually descends as shown in FIG.
When the lower end is reached as shown in (c), the bottle chuck 11 supported by the lower end of the bottle chuck holder 12 accordingly presses the bottle 3 to some extent and the nozzle portion 3E.
Cover. In this way, the bottle chuck 11 descends together with the bottle chuck holder 13 because the bottle chuck 1
1 is connected to the motor 17 via the double pipe 15 and the clutch 16, and the respective pipes of the double pipe 15 do not rotate relative to each other, but one pipe (the pipe having the bottle chuck 11 at the lower end) in the axial direction is This is because it can be moved.

In this way, the bottle chuck 11 is attached to the bottle 3
When compressed air is supplied to the bottle chuck 11 through the air tube 18 while covering the nozzle portion 3E, the nozzle portion 3E is gripped by the fluctuation of the chuck rubber 11a in the bottle chuck 11. Immediately after this, when the motor 17 is driven and the bottle chuck 11 holds the bottle 3 via the clutch 16 and the double pipe 15 and rotates as shown in FIG. 4, the claw 6A gradually slides into the recess 3B along the tapered surface 3C of the recess 3B, and finally the claw 6A fits into the flat surface 3D of the recess 3B, as shown in FIG. , FIG. 5 (c)
As shown by, the holding claw 6 is completely fitted in the recess 3B, the bottle 3 is positioned and aligned in a certain direction, and the bottle chuck 11 and the bottle 3 do not rotate any more.
That is, when the motor 17 rotates the bottle chuck 11 by 180 °, the clutch 16 is automatically released to prevent the bottle chuck 11 from rotating any more.
Such a series of alignment is performed while the bottle chuck 11 flows while maintaining the lowest end.

After that, when the alignment of the bottles 3 is completed, the supply of the compressed air through the air tube 18 is automatically stopped, the fluctuation of 11a disappears, and the nozzle portion 3E is released from the bottle chuck 11. After that, the bottle chuck 11 keeps the bottle 3 in the bottle holder 1 and the cam rail 1
4, the bottle 3 starts to rise gradually according to the ascending gradient of 4, and returns to the original height to complete a series of alignment operations, and the bottle 3 flows to the next step together with the bottle holder 1.

Next, the operation of the bottle holder 1 will be described with reference to FIGS. 6 and 7 based on the operation of the bottle holder 1 at the time of labeling the bottle by the rotary type bottom plate pushing device for labeling. Shaft core of bottle holder 1 that flows through the push-up process and bottom plate lifting plate 2 of the push-up device
1 and the slider 22 supporting the same, the bottle holder 1 flows through the line in a state of being surely aligned. When the bottle holder 1 flows in this pushing up process, the cam followers 23 of the slider 22 move in the horizontal portion of the cam rail 24 in synchronization with this, and in this state, the support member 4 is placed on the bottom surface portion 2A of the holder body 2. It is in a state (Fig. 6
(A) and FIG.7 (a)). From the horizontal part, see FIG. 6 (b).
As shown by, rise gradually according to the uphill slope, and lift plate 2
1 passes through the opening 2E of the holder body 2 and comes into contact with the bottom surface of the support member 4 to push up the support member 4 from the bottom surface portion 2A of the holder body 2 as shown in FIGS. 6 (b) and 7 (b).

At this time, the first permanent magnets 8, 8 in the space 4B of the support member 4 are disengaged from the second permanent magnets 9, 9 of the holder body 2, and the repulsive force between them disappears. As a result, the pair of holding claws 6, 6 is released from the repulsive force, and the coil spring 7
By the urging force of the holding claws 6, the claw portions 6A, 6A of the holding claws 6, 6 are elastically brought into close contact with the outer peripheral surfaces of the concave portions 3B, 3B of the bottle 3.
As a result, the bottle 3 is firmly fixed on the support member 4 without rattling (see FIG. 7B).

In this state, when the bottle holder 1 gradually rises according to the ascending slope of the cam rail 24 and reaches the rising end as shown in FIGS. 6 (c) and 7 (c), the bottle 3 is positioned on the support member 4. Almost outside the holder main body 2 in the kept state. Then, the label 10 is attached to the bottle 3 as shown in FIG. 6D while the cam follower 23 moves along the horizontal portion of the rising end. After that, the cam follower 23 follows the descending slope of the cam rail 24, as shown in FIG.
As shown in FIG. 6A, it gradually descends, returns to the horizontal part of the original height at the descending end as shown in FIG. 6F, and ends a series of labeling steps, and the bottle 3 flows to the next step together with the bottle holder 1. . Even if the bottle 3 is returned to the inside of the bottle holder 1 by performing the labeling as described above, since the bottle 3 moves in and out of the holder main body 2 in the positioned state, the positioning (centering) is performed once as described above. If so, there is no need to perform any positioning operation in the subsequent steps.

As described above, according to the bottle holder 1 of this embodiment, the holder claws 6, 6 of the support member 4 and the concave portion 3B provided on the bottom surface 3A of the bottle 3 are used in the holder body 2. Since the bottle 3 is positioned,
Even if the resin bottle 3 is formed in a thin shape, the bottle 3 can be positioned and held in the holder body 2 without deforming the shape, and filling of liquid can be performed accurately. Can be done. Also, bottle 3
There is no risk of scratching the. Further, since the bottle 3 positioned by the holding claws 6 on the support member 4 can be put in and taken out from the holder body 2 together with the support member 4, the holder 3 can be positioned without merely positioning the bottle 3 from the holder body 2. It is possible to perform accurate labeling such as labeling and printing while the body 2 is being released. Further, since the holder main body 2 is provided with the guide member 5 for guiding the support member 4 up and down, when the bottle is subjected to decoration such as labeling, the bottle can be stably taken in and out of the holder main body 2. In addition, since the bottle 3 is supported from the bottom, it is not affected by the shape of the bottle itself as compared with the conventional case.

The present invention is not limited to the above embodiment, and the design can be appropriately changed as necessary. For example, the material of the spring 7 is not particularly limited as long as it is an elastic member that can apply an elastic biasing force to the holding claw 6. Further, the concave portion 3B of the bottle 3 is not limited to the circular arc shape, and can be various shapes such as a triangle.
