KR940019578A - Case unloading device - Google Patents

Abstract

The present invention is a case unloading device for mechanically loading or unloading a case formed in the shape of a quadrangle or trapezoidal shape, etc., in order to elevate each case group of a plurality of rows stacked on a pallet for lifting. One row is placed on the conveyor belt one by one, and the case group on the upper side except for the lowermost case interposed on the conveyor belt for lifting is maintained in a horizontal posture with left and right support arms.

The lowermost case is removed by lowering the conveyor belt in the city, and the lowermost case is transferred to the conveyor belt so that it does not have a form or structure for supporting by hand and has a slippery side. It is characterized in that the loading and unloading is mechanically performed.
