Description

  The present invention relates to a food transport device such as a transport conveyor for transporting a display board on which food doughs such as bread and confectionery are placed. More specifically, the present invention is transported to a connecting portion of a plurality of transport conveyors. Foods that are placed on the display plate with transfer and transfer means for holding the bottom surface of the display plate in contact or non-contact and transferring it from the previous transfer conveyor to the subsequent transfer conveyor without applying vibration to the display plate The present invention relates to a food conveying apparatus capable of improving the quality of food.

  Conventionally, in the manufacturing process of food such as bread and confectionery, a plurality of transport conveyors such as chain conveyors, belt conveyors, roller conveyors, etc., of a predetermined length are used as a means for transporting food doughs, and have a predetermined shape. Food doughs such as bread and confectionery that have been molded into a plate are placed on a display board and carried on a conveyor.

  In particular, in the bread production process, a plurality of units that carry a food plate with a food plate placed thereon and convey it at a predetermined speed on a conveyance path that connects the final fermentation step of the food dough and the baking step (for example, a tunnel oven). The conveyor apparatus which connects these conveyors is installed (for example, refer patent document 1 and patent document 2).

  However, the transport conveyor installed in the transport path connecting the final fermentation process and the baking process (oven) is installed by connecting a plurality of transport conveyors such as chain conveyors formed to a predetermined length (captain). Therefore, the display plate on which the food dough is placed is vibrated up and down due to the unevenness of the connecting portion of the connection portion of the transport conveyor, and this adversely affects the form and quality of the food dough formed in a predetermined shape placed on the display plate. There was a problem.

In other words, the final fermented food dough is soft and unstable in shape, and there are bubbles in the dough, and the outer shape of the dough deforms when the display plate vibrates up and down at the connection part of the conveyor. If the dough is crushed or deformed in this state, baking the food dough in the baking process (oven) in this state will cause the appearance to break down, resulting in a recessed product, resulting in a defective appearance or quality of the product. was there. Another reason for the vertical vibration of the display plate is that the transport of the display plate is not currently controlled on the transfer conveyor, so that the display plates collide with each other when the display plate stops, and vibrations occur. Because of the wide crossing at the connecting part of the conveyor (the connecting part is wide), vertical vibrations occur at the connecting part of the conveyor, and the spreading plate can be warped during manufacturing and use, thus amplifying the vibration. It was the cause.
