[0002]
[Prior art]
Conventionally, a palletizer is known in which a plurality of articles are stacked on a pallet so that they can be loaded and unloaded by a forklift or the like. A pallet is placed on a lifter and a plurality of articles conveyed from a conveyor are stacked vertically. It is generally configured so that it can be stacked and stacked in a predetermined quantity so that it can be handled, transported and stored by a forklift. It supports and aligns the items stacked vertically so that they do not protrude from the pallet. It has a vertical back plate that can be moved forward and backward.
[0003]
By the way, since the articles stacked on the pallet are conventionally loaded from the pallet to the cart and transported to a predetermined place at the time of shipment, transfer work is wasted. Therefore, a method has been studied in which goods can be stacked with the cart directly fixed on the pallet, and the transfer work can be omitted to efficiently ship. However, when the articles are stacked on the pallet on which the cart is fixed, if the articles stacked on the back plate of the conventional palletizer are arranged, the back plate interferes with the cart.
[0004]
[Problems to be solved by the invention]
The problem to be solved by the present invention is an article using a palletizer that eliminates these conventional problems and enables the back plate to support and reliably align only the article on the cart without interfering with the cart. The purpose is to provide delivery facilities .
[0005]
[Means for Solving the Problems]
The configuration of the present invention that solves this problem is as follows.
1) A pallet is installed at the end of the conveyor for supplying articles, and a palletizer is installed on the pallet for lifting the articles to be supplied by the conveyor. This is a goods delivery facility equipped with a pallet and a mixed conveyor that can transport a cart pallet that can be detachably fixed to the upper surface, and a palletizer that carries the pallet loaded with the palletizer. The palletizer is provided with a vertical back plate on the opposite side of the lifter to the conveyor so that the vertical plate can be moved forward and backward. The back plate is advanced to the conveyor side and a plurality of supplied articles are applied to the back plate surface. It can be stacked on the pallet while being in contact with each other , and the back plate can be divided into a plurality of upper and lower parts to advance and retract independently. The back plate divided according to the packing state of the pallet is selectively advanced and retracted so that the back plate abuts only the item, and the lower end of the upper back plate divided by the palletizer is installed in the lifter. When the items are stacked on the pallet to which the cart is fixed, the back plate is moved forward with the cart so that the cart is stacked on the pallet to which the cart is fixed. An article unloading facility using a palletizer that prevents the interference and stacks articles on a plurality of types of pallets .
[0006]
[Action]
According to the present invention, the back plate for aligning a plurality of stacked articles is divided into two parts for the pallet position and the cart position, and when the plurality of articles are stacked on the pallet to which the cart is fixed, By advancing only the plate, the back plate contacts and aligns only with the article without interfering with the pallet. When stacking articles on a regular pallet, they can be aligned by advancing the divided upper and lower back plates simultaneously.
[0007]
In the present invention, when the pallet installed on the lifter is such that the cart can be freely attached to and detached from the upper surface, the lower end of the divided upper back plate is configured to be higher than the article loading surface of the cart, When stacking articles on a pallet with a fixed base, only the upper back plate is advanced so that the back plate does not interfere with the cart.
[0008]
In addition, when the back plate is divided into a plurality of pieces in the vertical direction, even if the articles to be stacked are different in size and shape, it is possible to arrange them individually at an arbitrary position on the back plate and load them in a balanced manner. When this palletizer is provided in the middle of a line in which a plurality of types of pallets having different article stacking surfaces are mixed and flowed, the palletizer is useful in that articles can be stacked in series on a plurality of types of pallets.
