Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pallet loading device for placing bagged items such as cement, fertilizer, feed, etc. onto pallets.

Conventionally, in a device for loading bagged items onto a pallet, the items are supported side by side on a carriage, and the carriage is moved with the bagged items held in place by a stopper.
When items on a carriage are dropped and placed on a pallet waiting below, as the carriage moves to one side, the items packed in bags move in the direction of carriage movement and are filled into bags. Objects tend to shift to one side, so when items are placed in multiple stages on a pallet, they tend to tilt.
Particularly in the case of powdered materials or products packed in bags, the contents tend to be uneven in the bag, causing the bag to collapse.

The present invention has been made in view of the above points, and by pressing and supporting the articles supported on the carriage in parallel with a plenosa and loading them onto the pallet, it is possible to prevent the articles from shifting on the pallet in the direction of movement of the carriage. Furthermore, by making the top surface of the item concave with a plenosa and fitting the uneven parts between the upper and lower items, it is possible to prevent the items stacked one above the other from shifting laterally. This allows for safe loading of items without the entire item tipping over.
