Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves installing a roller-type furnace conveyor in which a large number of rollers are arranged in parallel inside a tunnel-shaped furnace body, and transporting objects to be fired on the furnace conveyor in one direction. The present invention relates to a device for arranging baked products in a fixed array to be carried out from a conveyor in the furnace in a roller tunnel furnace for continuous firing.

When firing a flat object such as a tile in a roller tunnel furnace, it is fired continuously while being carried directly on a roller conhair installed in the furnace without using a sagger or a bed plate. However, since each roller that makes up the roller conveyor installed in the furnace is bent due to thermal deformation, it is possible to avoid changes in the posture and mutual positional relationship of the objects to be fired during conveyance. Therefore, in order to transfer the baked products onto a narrow belt conveyor and transport them to a boxing position, it is necessary to line up the W products at the exit side of the roller conveyor.

For this reason, even in conventional roller tunnel furnaces, an unloading roller conveyor with a high conveyance speed is installed on the exit side of the roller conveyor laid inside the furnace, and when transferred to this unloading conveyor, the products do not touch each other. In addition to widening the interval in the conveyance direction, an alignment plate is provided on the downstream side of the unloading conveyor that protrudes from below the conveyance surface at regular intervals, and the products traveling on the conveyor are brought into contact with the alignment plate. Aligning devices are used that align the products and release the discharge intermittently. However, these sorting plates do not allow the following products to collide and overlap each other during the arrangement, or cause the products to be aligned while they are running. Sometimes the product was pushed up with a board and blocked in a tilted position, resulting in uneven products being released.

The present invention eliminates these drawbacks and allows baked products to be
The object of the present invention is to provide a device that can actually align MM.

Embodiments of the present invention will now be described with reference to the accompanying drawings.
