Device and method for detecting neglected loading of magnet buckle of food packaging box

Abstract

The invention discloses a device and method for detecting neglected loading of a magnet buckle of a food packaging box. The device comprises a belt support and a conveying belt installed on the belt support, a servo conveying motor driving the conveying belt to work is further installed at the front end of the belt support, and a motor controller is arranged adjacent to the servo conveying motor; a magnet detection sensor, a gift box positioning detection sensor and an air cylinder telescopic arm are sequentially arranged on one side of the belt support in the longitudinal direction, a control module is installed on the belt support, the gift box positioning detection sensor is connected with the control module through an electric wire, and an unqualified product collecting channel is formed in the position, right opposite to the air cylinder telescopic arm, of the belt support. The belt support is further provided with an electromagnetic valve for controlling the telescopic arm of the air cylinder to work, and the control module is connected with the motor controller, the electromagnetic valve and the magnet detection sensor through wires. According to the invention, it can be effectively guaranteed that all the bottom boxes entering the assembling machine are qualified and normal, and waste products caused by the absence of magnet buckles are reduced.

Description

technical field [0001] The invention relates to the field of printing, in particular to an assembly box magnet detection device and method for a food packaging box. Background technique [0002] In the prior art, the Tiandigai food packaging box is mainly composed of the following parts: 1. The cardboard of the packaging box is slotted according to the designated position; 2. The slotted cardboard is manually placed into the fixed position of the cardboard with a magnet; 3. The fixed magnet buckle and the cardboard are fixed between the cardboard and the surface of the printed matter through the line of action of the cot machine. 4. The bottom cover with two magnet buckles and the surface are transported to the position of the assembly mechanism through the conveyor belt. The lids come together to form a perfect box. Since the magnetic buckle is pasted manually with glue, it will cause falling off during the pasting process, or it will fall off before being transported to t...

AI Technical Summary

Problems solved by technology

Since the magnetic buckle is pasted manually with glue, it will cause falling off during the pasting process, or it will fall off before being transported to the device and on the machine. When the entire packaging box is assembled, it is found that one or two of the magnetic buckles are missing. A magnet buckle, resulting in a waste of manpower and material resources and raw materials, affecting delivery time
