Description

Visual detection device for few cigarettes in carton

Technical Field

The utility model belongs to the technical field of tobacco, and particularly relates to a few-tobacco-strip visual detection device for cigarette carton packing.

Background

The cigarette carton is packed into the carton by the box filling machine, and during operation, the cigarette carton stacking is placed in front of the carton, the cigarette stacks are pushed into the cigarette carton by the push rod, then the cigarette carton is erected by the carton erecting mechanism of the box filling machine, and finally the cigarette carton is transported away by the roller conveyor arranged at the outlet of the box filling machine. In the cigarette carton boxing process, the cigarette cartons which are less packed may be less packed due to mechanical, electrical or operation reasons, and the cigarette cartons which are less packed with the cigarette cartons are judged to have serious quality defects after entering a finished product warehouse. After trying out methods such as inductance detection, ray detection, weighing detection and the like, a visual detection method is selected mostly according to options such as environmental safety, reliability and the like. However, in many of the currently used visual inspection devices (or systems) for packing few cigarettes, there are irregular cigarettes in the stack after the first stack is pushed into the box for a number of reasons as described below. The stack is composed of several layers of tobacco rods, and fig. 5 is a schematic view of visual detection effect of the packaged few tobacco rods without the tidy function of the tobacco rods.

The uneven leading reason of tobacco rod in the tobacco pile after first tobacco pile pushes the smoke box is as follows:

a. the push plate (25) loses control effect on the tobacco stack in the process of deceleration and stop after being pushed out;

b. when the first cigarette stack is pushed in, the middle cigarette strip on the upper layer has a sliding-out space;

fig. 6 is a schematic view of a carton and a socket of the carton when the tobacco strips are tidy, and fig. 7 is a schematic view of a cross section of the carton socket when the tobacco strips are tidy. The pushing plate only pushes the tobacco stack to be flush with the opening of the tobacco box (21) every time the pushing plate pushes the tobacco stack, and the tobacco stack does not enter the tobacco box. The first stack is pushed in without obstruction in front of it.

The size of the smoke box (21) is designed by considering that four corner sockets (24) are inserted, and the middle part of the uppermost layer of the smoke box (21) has a clearance of more than 5mm after the smoke stack is pushed.

c. The friction force of the cigarette in the middle of the upper layer is the smallest and the cigarette is most easy to slide out due to the gravity factor, the material friction coefficient and the contact surface factor;

the more downward the stack is subjected to the greater pressure generated by gravity, the greater the friction force the stack is subjected to when pushed in, and conversely, the more upward the friction force is subjected to is smaller and the more easily the stack slides out.

The friction coefficient of the transparent plastic films between the cigarette sticks (22) is smaller than that of the cigarette box (21) and the cigarette sticks (22), the corresponding friction force is also small, and the cigarette stick in the middle of the uppermost layer of the cigarette stack is small in friction force and easy to slide out.

The uppermost surface of the cigarette strip in the middle of the uppermost layer has no contact object, the friction force of the friction surface is reduced, and the cigarette strip in the middle of the uppermost layer of the cigarette stack has small friction force and is easy to slide out.

d. The size of part of the box is large, and the gap between the upper layers of the box and the cigarette stack is large after the cigarette stack is pushed;

the size of the new carton of some parts is large, if the size of the cigarette case is larger than that of the new carton, the cigarette case is recycled for a plurality of times, the gap is larger, and the sliding space of the upper layer of cigarette sticks is larger.

e. The speed of upstream cigarettes and packaging equipment is greatly improved, the speed of box sealing equipment is also greatly improved, the pushing speed of the cigarette stack is also greatly improved, and the middle parts of the layers of cigarette stacks are easy to slide out irregularly due to the increase of the speed.

The cigarette strips in the cigarette stack are very irregular after the first cigarette stack is pushed into the cigarette box, the position difference of the end of the cigarette strip in the cigarette stack is more than 150mm at most, the visual effect of the cigarette strip above the middle is very similar to that of the cigarette stack with the missing strip when the cigarette strip slides out too much, the difference of the cigarette stack in the images with the missing strip and the image without the missing strip is small or even zero, the difference between the cigarette stack and the image is difficult to identify by visual detection software, the adjustable space of the visual detection sensitivity is small, and the adjustment and the detection are difficult; the detection precision is reduced due to small difference, so that fewer cigarette boxes are not detected and rejected; a large amount of wrong removal is generated, the workload of manual reexamination and carrying of the wrong removal of the cigarette boxes is large, and even the cigarette boxes cannot work normally due to the large removal amount.
