Abstract

The present invention relates to an egg carton stacking device with an improved direction-changing function. The disclosed egg carton stacking device with an improved direction-changing function comprises a conveying conveyor belt member, a stacking conveyor belt member, a direction-changing member, and an egg carton alignment member. Since the direction-changing member comprises a direction-changing body, a direction-changing section, and a direction-changing side moving section, the direction-changing egg carton can be aligned to a predetermined position. Furthermore, since the direction-changing section includes a shock absorber, damage to the egg carton can be prevented even if it collides with the direction-changing member.

Description

Egg carton stacking device with improved turning capability The present invention relates to an egg carton stacking device with an improved direction changing function. An egg carton is a packaging container for eggs, and serves to protect the eggs from breaking when storing or transporting them. The egg carton comprises a bottom plate formed with multiple grooves so that the eggs can be placed one by one, made of paper that is strong for cushioning and has a certain strength, such as corrugated cardboard; a cover plate made of thin and light plastic or paper so that the top of the egg carton can be covered when the eggs are placed in the bottom plate; and a binding string that binds the bottom plate, the eggs, and the cover plate in sequence. The above egg cartons generally need to be in a stacked form to facilitate handling, such as transportation and sales. A device for stacking multiple egg cartons as described above is an egg carton stacking device, and such an egg carton stacking device is the one described in the patent document presented below. Generally, an egg carton stacking device is equipped with a direction changing member that allows one of the plurality of egg cartons to be transported as is and another egg carton following one of the plurality of egg cartons to be transported after being changed direction by 90° so that the plurality of egg cartons moving continuously on the conveyor belt can be stacked together. However, according to the conventional egg carton stacking device including the patent document presented below, the direction changing member is formed to move perpendicularly to the conveying direction of the egg carton on the conveyor belt and simply catches on the side of the egg carton, so the alignment of the turned ones is different, and there was a problem that the operator had to check the position of the turned ones from the side and, if necessary, manually align them, and there was a problem that the egg carton was damaged due to impact when the egg carton collided with the direction changing member while being conveyed on the conveyor belt.
