State detector for push plates of packing machine

Abstract

The invention relates to a state detector for push plates of a packing machine. The packing machine comprises a stacking lifter for lifting a packed object and a pushrod arranged above the stacking lifter. A first push plate and a second push plate are independently arranged on the two sides of the pushrod respectively, and are connected with the two sides of the pushrod through a spring respectively. The state detector further comprises a controller, and a first photoelectric detector and a second photoelectric detector, which are connected with the controller and arranged on the two sides of the first and second push plates respectively. The first and second photoelectric detectors are used for detecting the movement of the first and second push plates respectively. A path of output of the controller is connected with a shutdown signal output line of the packing machine, and the other path of output of the controller is connected with an alarming mechanism of the packing machine. The working states of springs of the push plates and the push plates of a CH packing machine are effectively detected, so that serious quality defects of cigarette packet products caused by the breakage or separation of resetting springs of the push plates are prevented.

Description

technical field [0001] The invention relates to a tobacco automatic control device, in particular to a state detector of a push plate of a packaging machine. Background technique [0002] CH packaging machine is a cigarette packaging equipment that wraps OPP cellophane on the outside of cigarette packets. see Picture 1-1 , Figure 1-2 , figure 2 with image 3 , the cigarette pack 7 wrapped with OPP cellophane is lifted up by the stack lifter 1 to form a stack of two packs of cigarette packs together, and then the CH push rod 4 pushes the stack of cigarette packs forward. The first push plate 6 and the second push plate 2 are respectively arranged on both sides of the CH push rod 4, and the first push plate 6 and the second push plate 2 are connected with the CH push rod 4 through a round pin, and can move flexibly on the round pin . The springs 5 ​​and 3 respectively pull the first push plate 6 and the second push plate 2 to a vertical state. When CH pusher 4 moves f...
