DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transferring containers. More specifically, the present invention is a container transfer device for transferring bottles and other containers along a transfer path having a height difference.When the container transfer device of the present invention is used, the size and shape of the container are different. By using the same device, containers can be removed without dropping containers from the conveyor or congestion of containers.
Transfer can be smoothly and continuously performed along a transfer path having a difference in elevation.

[0002]

2. Description of the Related Art While continuously transferring bottles and other containers by a transfer device such as a conveyor, filling the containers with contents, washing the containers, labeling the containers, sorting and collecting used containers, Conventionally, processes such as pulverization and reuse have been widely performed. In such a case, the transfer route of the container is provided with a height difference in order to reduce the area occupied by the entire transfer device and effectively use the site, and to improve work efficiency and improve the work environment. It is common practice to make systems three-dimensional.

In a transfer system having a three-dimensional structure in which a height difference is provided in a transfer path of a container, simply placing the container on a conveyor causes the container to be transferred from a low place to a high place or from a high place of the container. Since the containers fall off the conveyor when transported to a low place, it is necessary to provide means for dropping the containers from the conveyor. Conventionally, as a means for preventing the container from falling off in a transfer path having a height difference, as shown in a schematic diagram of FIG. 1, a body portion of the container 1 is made of rubber or the like at a location of the transfer path having a height difference. A method is adopted in which the container 1 is transported from a low place to a high place or from a high place to a low place while being held between a pair of left and right holding conveyors (holding belts) 2a and 2b that stand upright.

However, in the case of the above-mentioned conventional method, the distance between the holding conveyors (holding belts) 2a and 2b provided on both sides of the transfer path is constant. It is extremely difficult or impossible to transfer various containers having different diameters to a transfer path having a height difference. That is, the diameter of the body of the container is left and right holding conveyors (holding belts) 2a,
If the distance is smaller than 2b, a gap is generated between the left and right holding conveyors (holding belts) 2a and 2b and the container, so that the container cannot be held, and the container falls to a low place at a place having a height difference. As a result, the container cannot be transferred from a low place to a high place, or the container cannot be continuously transferred to a low place when transferring from a high place to a low place. On the other hand, when the diameter of the body of the container is larger than the interval between the left and right holding conveyors (holding belts) 2a and 2b, the left and right holding conveyors (holding belts) 2a and 2b are used.
b, the container cannot be brought in, and congestion of the container occurs before the nipping conveyors (nipping belts) 2a and 2b.
Again, the transfer from a low place to a high place or the transfer from a high place to a low place becomes impossible.

Further, in the case of the conventional apparatus shown in FIG. 1, when the apparatus is used for transferring a container having a specific size A and then used for transferring a container having another size B, the right and left sides are required. A pair of holding conveyors (holding belts) 2a, 2b
Must be changed in accordance with the size of the container having the other size B (the size of the body). However, since the change in the interval between the holding conveyors (holding belts) 2a and 2b involves a change in the entire apparatus, a heavy load is required on the apparatus and work surfaces.

[0006]
