AI Technical Summary
In the traditional method of cutting and re-baking production line storage cabinet fabric, the fabric truck conducts material layer detection and control through reciprocating movement, resulting in lag in feedback of the material layer thickness information, making it difficult to accurately control the displacement distance of the fabric truck, resulting in peaks and troughs of the storage cabinet material, uneven material layer, and easy to block material when discharged.
The laser distance sensor is used to directly measure the position of the fabric truck above the storage cabinet to avoid the lag of the motor control. Combined with the forward and reverse rotation method of the fabric conveyor belt, the precise fabric for the two storage cabinets is achieved, the displacement of the fabric truck is reduced, and the accuracy of the material truck position control is improved.
By accurately controlling the position of the fabric truck, the uneven thickness of the material layer is reduced, the problems of blockage and uneven discharge during discharge are reduced, and the uniformity and efficiency of the discharge of the cabinet material are improved.

The discharge conveyor belt 5 is used to transport the materials stored in the storage cabinets to their respective discharge ports. The feed ports of the two storage cabinets are located above the storage cabinets; the input conveyor belt is arranged above the middle of the two storage cabinets. Specifically, the input conveyor belt can be arranged directly above the discharge ports of the two storage cabinets. The input conveyor belt is used to input the materials to be stored into the storage cabinets; the output conveyor belt is arranged below the middle of the two storage cabinets. Specifically, the output conveyor belt can be arranged directly below the discharge ports of the two storage cabinets. The output conveyor belt is used to receive the materials transported from the discharge ports by the two discharge conveyor belts 5 and transmit the materials to the next process; the distribution vehicle is movably arranged above the two storage cabinets and between the two storage cabinets and the input conveyor belt. The material cart can move along the arrangement direction of the two storage cabinets.
