Description of the Related Art Conventionally, as a container transport mechanism for transporting containers, there is provided a rotatable rotatable member, and a clamp mechanism provided on the rotatable member, which is opened / closed and grips a neck portion of a supplied container. Is known (Japanese Patent Laid-Open No. 4-1
No. 29921). With this type of container transport mechanism, it is possible to handle many types of containers because the container can be gripped and transported with the neck of the container having a small change in diameter compared to the body of the container. There is.

[0003]

However, if the container is gripped and conveyed in a suspended state, the bottom of the container is swung by centrifugal force, and the container is incompletely gripped and falls off. Or the bottom of the container collides with another member or the container. In particular, there is a drawback that when two container transport devices are provided side by side and the containers are transferred from the first container transport mechanism to the second container transport mechanism, the containers cannot be delivered smoothly. In order to solve the above-described problems, it is conceivable to provide a mounting plate for supporting the bottom of the container on the rotating body, prevent the bottom of the container from being swung by the mounting plate, and stably convey the container. . However, in this case, for example, when two container transfer devices are provided side by side, the height of the mounting plate of the first container transfer device and the height of the mounting plate of the second container transfer device are reduced. Since they must be provided differently, there is a disadvantage that the container cannot be delivered or received due to a step between the first mounting plate and the second mounting plate.
The present invention has been made in view of the above-described circumstances, and provides a clamp-type container transfer device that can stably transfer a container and can smoothly transfer a container from a first container transfer mechanism to a second container transfer mechanism. Things.

[0004]

That is, the present invention provides a first rotating body rotatably provided, a first mounting plate provided on the first rotating body, on which a container is supplied and mounted, and 1
A first container feeding mechanism including a first clamp mechanism that is provided on the rotating body and that is opened and closed and grips the supplied container;
A second rotatable member rotatably provided, a second mounting plate provided on the second rotatable member to supply and mount the container, and a second clamp provided on the second rotatable member for gripping the container And a second container transport mechanism having a mechanism, wherein at least one of the first clamp mechanism and the second clamp mechanism grips the neck of the container and receives the container from the first clamp mechanism to the second clamp mechanism. The first mounting plate supports substantially half of the container on the rotation center side of the first mounting plate, and the second mounting plate supports the second mounting plate. Approximately half of the bottom of the container, which is the center of rotation of the plate, is supported, and the first mounting plate and the second mounting plate simultaneously support the bottom of the container at the transfer position of the container. .

[0005]

According to the above arrangement, the container is placed on the mounting plate and transported with the neck held by the clamp mechanism. Can be prevented from being swung by the centrifugal force as much as possible, and the container can be transported stably. When the container is delivered from the first container transport mechanism to the second container transport mechanism, the bottom of the container is simultaneously supported by the first mounting plate and the second mounting plate, and In this state, the first clamp mechanism and the second clamp mechanism grasp the neck of the container at different heights and transfer the container from the first clamp mechanism to the second clamp mechanism, so that the container is smoothly transported to the first container. It is transferred from the mechanism to the second container transport mechanism.

Thus, the above-mentioned container transport mechanisms 4, 8, 12
Since all have the same configuration in the basic configuration, the configuration of the first container transport mechanism 4 will be described. The first container transport mechanism 4 includes a hollow fixed shaft 20 disposed in a vertical direction as shown in FIG.
And a hollow drive shaft 21 rotatably supported therein. The first rotating body 7 is provided at an upper end of the hollow drive shaft 21.

A connecting plate 30 is fixed to an upper end of the outer cylindrical member 25, and the connecting plate 30 is rotatably mounted on an upper end of a lifting rod 31 which penetrates through the hollow drive shaft 21 so as to be able to move up and down. It is attached to. The lifting rod 31 can be raised and lowered by a lifting device (not shown), and the hollow drive shaft 21 can be driven to rotate in the above-described counterclockwise direction in conjunction with a driving mechanism (not shown). I can do it.
Therefore, the outer cylindrical member 25 and the upper disk 26 can be raised and lowered by raising and lowering the lifting rod 31, and the inner cylindrical member forming the first rotating body 7 can be driven by rotating the hollow drive shaft 21. -Shaped member 22, lower disk 2
3. The outer tubular member 25 and the upper disk 26 can be integrally rotated.

Next, a plurality of first clamp mechanisms 6 each having a pair of clamp arms 6a and 6b are provided at equally spaced positions on the outer periphery of the lower disk 23 and the upper disk 26 (FIG. 1). reference). Each first clamp mechanism 6 includes a pair of clamp shafts 32a (see FIG. 1) and 32b whose upper ends are rotatably connected to the upper disk 26, respectively, and the lower ends of the clamp shafts 32a and 32b are lower. A hollow shaft 33 rotatably supported by the side disk 23 is penetrated so as to be able to move up and down. A pair of clamp arms 6a and 6b are mounted on each pair of clamp shafts 32a and 32b, and a gear 34 (one not shown) is attached to each pair of the clamp arms 6a and 6b, so that one clamp shaft 32a is fixed. When rotated in the opposite direction, the pair of clamp arms 6a and 6b can be opened and closed via the gear 34. Therefore, as described above, the pair of clamp arms 6a and 6b can be moved up and down by raising and lowering the upper disk 26, whereby the pair of clamp arms 6a and 6b can be moved to the optimum position in accordance with the height of the container 2. Can be adjusted.

The lower disk 23 is provided with a cylindrical member 33 extending vertically through the lower disk 23.
A hollow shaft 34 is rotatably supported in the cylindrical member 33. A key 35 is attached to the inner periphery of the hollow shaft 34, and the key 35 is engaged with a key groove 36 formed in the axial direction of the outer peripheral surface of the clamp shaft 32 b, so that the clamp shaft 32 b They are connected so that they can rotate integrally while allowing up and down. One end of a swing lever 38 constituting the cam mechanism 37 is fixed to the lower end of the hollow shaft 33.
A cam follower 39 is attached to the other end. On the other hand, a cam member 40 is fixed to the upper end of the hollow fixed shaft 20, and the clamp arm 6 is provided by a spring (not shown) provided between the lower disc 23 and the swing lever 38.

The holding position of the container 2 by the first clamp mechanism 6 of the first container transfer mechanism 4 and the holding position of the container 2 by the second clamp mechanism 10 of the second container transfer mechanism 8 adjacent thereto are as follows. Naturally, the height positions are different so that the two clamping mechanisms 6, 10 do not interfere with each other. Also,
The first mounting plate 5 of the first container transport mechanism 4 is closer to the rotation center side of the first mounting plate 5 than the center line O (see FIG. 2) of the container 2 gripped by the first clamp mechanism 6. And a second container transport mechanism 8
Of the container 2 held by the second clamp mechanism 10 (not shown) with respect to the center line O of the container 2.
The first mounting plate 5 and the second mounting plate 9 are set at the same height so as to support substantially half of the container 2 which is the rotation center side of the mounting plate 9. The bottom portion of the container 2 can be supported at the same time at the transfer position of the container in between. That is, the first mounting plate 5 of the first container transport mechanism 4 and the second mounting plate 9 of the second container transport mechanism 8 respectively have the center line O of the container 2.
By supporting the rotation center side more, it is possible to prevent interference between the first mounting plate 5 and the second mounting plate 9 and to provide both mounting plates 5 and 9 at the same height position. I have. The first mounting plate 5 and the second mounting plate 9
It is not necessary to set so that the center of rotation of the container 2 is supported more than the center line O. If the bottom of the container 2 can be prevented from being swung by the centrifugal force, for example, the first mounting plate 5 The outer diameter is reduced so that approximately 30% of the bottom of the container 2 is supported, and the outer diameter of the first mounting plate 5 is set to be larger than the center line O of the container 2 so that approximately 70% of the bottom of the container is reduced. The supporting plates 5 and 9 may both be reduced in outer diameter to support the bottom of the container 2 by 30%. Such a configuration can be similarly applied to the second container transport mechanism 8 and the third container transport mechanism 12 adjacent to each other.

According to the above configuration, the container 2 is conveyed with its neck held by the first clamp mechanism 6 of the first container transport mechanism 4 and then delivered to the second clamp mechanism 10 of the second container transport mechanism 8. And the third container transport mechanism 12
It is delivered to the clamp mechanism 14. The change in the diameter of the neck of the container is generally smaller than that of the body of the container, so that many types of containers can be processed. When the container 2 is gripped and transported, the bottom of the container 2 is always supported by the mounting plates 5, 9, and 13 of the container transport mechanisms 4, 8, and 12, respectively.
Even if the neck of the container is gripped, the bottom of the container is less likely to be swung by the centrifugal force, whereby stable transport can be performed and smooth delivery can be performed.

In this embodiment, the first container transport mechanism 4, the second container transport mechanism 8, and the third container transport mechanism 12 are all configured to grip and transport the neck of the container 2. The present invention is not necessarily limited to this, and when it is difficult to simultaneously grasp and transfer the neck of the container with the clamp mechanism of one container transport mechanism and the clamp mechanism of the other container transport mechanism, one of the two is used. May be set so as to grip an appropriate portion such as the body of the container.

[0015]

As described above, according to the present invention, it is possible to stably transfer the container by gripping the neck of the container, and to smoothly receive the container from the first container transfer mechanism to the second container transfer mechanism. The effect of being able to pass is obtained.
