Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a container take-out and transfer method in which containers are sequentially transferred from a group of containers in the uppermost layer onto a conveyor from a multi-layered container body in which a plurality of containers arranged vertically and horizontally are stacked over multiple stages. Regarding equipment.

Generally, when transporting a large number of containers such as bottles, a plurality of containers arranged vertically and horizontally are transported in a state in which they are stacked in multiple stages via sheets.

By the way, when containers in each layer are sequentially transferred from such a stacked body onto a conveyor or the like and transported to a predetermined location, the stacked body is sequentially raised so that the containers in the top layer are aligned with the top surface of the conveyor. After that, both front and rear ends of the container group are held between a pair of clamping plates and the container group is moved onto a conveyor.

However, it is felt that the positions of the container groups in each layer of the laminate are shifted from each other during transportation.

Therefore, when the container groups in each layer are shifted from each other in the front-rear direction, the container group is directly supported and the sheet raised in the same plane as the conveyor is reliably gripped by the sheet gripping device. unable to hold, −
When a group of containers is moved toward the conveyor by the N clamp plate, the sheet itself also moves, making it impossible to transfer the group of containers onto the conveyor in an orderly manner, or causing the containers in the next layer to fall over. There are problems such as storage.

In view of these points, the present invention aims to provide a conveyance device for taking out containers from a multi-layered container body, which is capable of reliably and accurately holding a group of containers in each layer and smoothly transferring them onto a conveyor. purpose.
