Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work conveyer for collecting works to be conveyed while being suspended, such as a mouth member attached to a beverage container having a sheet formed in a bag shape.

[0002]

2. Description of the Related Art Conventionally, for example, a mouth member attached to a beverage container having a sheet formed in a bag shape is randomly arranged after being randomly charged into a parts feeder as a supply device. Then, each mouth member is transported to the manufacturing device by the transport device so as to be attached to the beverage container.

[0003]

However, since the supply capacity of the parts feeder is limited, the supply capacity of the parts feeder is generally inferior to the processing capacity of a manufacturing apparatus for attaching a mouth member to a beverage container. This is a factor that makes high-speed work impossible.

A work other than a work conveyed in a suspended state, such as a mouth member, can be conveyed while being placed on a conveyor device. For this reason, for the purpose of improving the carrying capacity, means for arranging the two screws in a V-shape, collecting the works supplied from the respective screws on a conveyor, and carrying them to the manufacturing apparatus in the next step is adopted. I have.

[0005] However, a work conveyed while being hung, such as a mouth member, cannot be placed on the conveyor device. Therefore, if a plurality of screws are employed, the work drops in a space which is a space downstream of the screws. Therefore, it is difficult to hold the workpieces conveyed from a plurality of transport devices.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and allows a plurality of works to be conveyed while being suspended to be assembled and conveyed by a plurality of conveying devices. It is an object to be able to improve.

[0007]

The technical measures taken by the present invention to solve the above problems are as follows. That is, a plurality of transport devices 7 for transporting the work 5 supplied from the work supply device 55 while being suspended by the guide means 8 are provided, and each of the transport devices 7 transports the work 5 so as to be gathered alternately. In addition, a guide selection means 17 for guiding the work 5 to the discharge unit 55 is provided at a downstream position of the transfer device 7, and the guide selection means 17 is provided with the work 5 transferred from one side and the guide selection means 17 from the other side. In order to select and lock the work 5 to be conveyed, the position is freely changed.

The work 5 conveyed from one side by the conveyance device 7 can pass through the work 5 by swinging the guide selecting means 17 to the other side, and the work 5 is moved by the swinging guide. Since it is locked by the selection means 17, it is guided to the discharge section in a suspended state by the guide selection means 17 and the guide means 8.

Further, the transporting device 7 has a screw 22 arranged in a V-shape, and the guide selecting means 17 is provided so as to be swingable in the horizontal direction. The upper guide part 35 pressed by each work 5 and the work 5 conveyed from one side are locked when the guide selection means 17 is pushed by the work 5 conveyed from one side and swings to the other. It is preferable that a lower guide portion 36 is formed so that the position where each screw 7 engages with the work 5 and the position of the upper guide portion 35 are approximately the same height.

In such a case, since the position where the screw 22 presses the work 5 and the position where the work 5 presses the upper guide portion 35 are at the same height, the work 5 swings or moves carelessly. Without screw 2
The pressing force for swinging the second guide selecting means 17 is as follows:
It can be reliably transmitted to the upper guide portion 35. Further, since the lower guide portion 36 is provided at a position different from the upper guide portion 35, the lower guide portion 36 can be formed into a shape that can be securely locked according to the shape of the work.
