Tray feed bin having self-checking function

Abstract

The invention discloses a tray feed bin having a self-checking function. The tray feed bin comprises a rack, a conveyor belt, a moving pallets, trays, a feeding lifting mechanism and a blanking lifting mechanism, wherein the conveyor belt is arranged at the upper portion of the rack; the moving pallets are arranged on the conveyor belt; the trays are placed on the moving pallets; positioning pins are arranged on the moving pallets; each tray comprises a square bottom surface and four sides; positioning holes allowing the positioning pins to penetrate through are formed in the bottom surface of each tray; a plurality of through holes distributed uniformly in the horizontal direction is formed in the upper edges of the sides; positions of through holes of two opposite sides correspond mutually; a limiting strip is movably connected with two corresponding through holes; and a weighing sensor is arranged on the blanking lifting mechanism. According to the tray feed bin having the self-checking function, sizes of workpiece fixing positions on the trays can be adjusted according to the sizes of workpieces; the situation of missing of workpieces can be reminded of; the operation is convenient; the investment is reduced; and the processing efficiency is improved.

Description

technical field [0001] The invention relates to a pallet storage bin with a self-checking function, which belongs to the field of pallet storage bins. Background technique [0002] In the automatic production line of mechanical parts, it is often necessary to complete the halfway packing and transshipment of blanks and semi-finished products, the loading and unloading of various processing equipment, and the loading and unloading of other processes such as assembly and sorting. [0003] The loading and unloading work of various machine tool equipment on the automatic production line of mechanical parts is generally completed by robots. The loading and unloading robot is mainly responsible for the pick-up, transmission, loading and unloading of the processed workpieces. First, the grasped workpieces must be placed in the position specified by the robot in an orderly manner, and the processed workpieces must also enter the unloading smoothly. The system facilitates the conver...

AI Technical Summary

Problems solved by technology

[0004] Pallets are often provided with neatly arranged workpiece fixing positions so that the loading and unloading robot can accurately grasp and position. In order to adapt to the size of different workpieces, it is necessary to customize the pallet with different specifications of workpiece fixing positions according to the size of the workpiece, and needs replacement, which results in a large investment in pallets when there are many types of workpieces
