Description

Lifting and stacking mechanism for breaking paper

technical field

The utility model relates to a mechanism for lifting and stacking before breaking paper, and belongs to the technical field of inspection machines.

Background technique

At present, as shown in Figure 1, the existing product inspection machine (also known as small-sheet printed matter inspection machine) generally includes a paper feeding mechanism 10, a deviation correction mechanism 20, and a surface quality inspection mechanism 30, wherein: the paper feeding mechanism 10 includes a paper feeding mechanism The device 11 and the paper feeding knife 13 and the paper support plate 12 correspondingly arranged above it, the deviation correcting mechanism 20 includes a pair of deviation correcting conveying devices 21 correspondingly arranged up and down, and the surface quality detection mechanism 30 includes a suction detection conveying device 31 and its upper corresponding Set the detection device 32. As shown in Fig. 1, during actual implementation, the printed matter stack 40 stacked up and down to be detected is placed between the paper feeding knife 13 and the paper support plate 12 with the printing surface facing up, and one end of the printed matter stack 40 is held by the paper support plate 12. Hold and the other end sticks to the paper feeding knife 13, and the bottom printed matter 41 is driven by the friction between the conveyor belt of the paper feeding conveying device 11 and output from the paper outlet, so the printed matter 41 to be detected Then they are output sheet by sheet continuously from the paper outlet, and then they are sent to the surface quality inspection mechanism 30 for printing surface quality inspection after being corrected and corrected sheet by sheet by sheet by sheet.

At present, the product inspection machine is mainly used for small hard cigarette labels (also known as hard cigarette boxes), and the detection speed can reach 130,000 pieces per hour. The height of the paper is limited. It can be seen from this that the labor intensity of manual paper loading is very high. Workers need to continuously feed the paper feeding mechanism 10 and cannot leave. But even so, a worker can only satisfy a maximum of one The paper loading requirements of the inspection machine. In addition, in order to prevent poorly cut printed matter 41 from entering the market as a genuine product, before putting the printed matter 41 on the paper feeding mechanism 10, workers need to perform paper breaking operations on the printed matter 41, that is, the four "ears" on the hard small cigarette label. ", that is, the folded ears, which need to be broken off (ie pressed out) before the paper is loaded, otherwise, when the paper feeding mechanism 10 is discharging the paper, the ears of the two overlapping printed matter 41 are easy to scrape together, thereby causing damage to the printed matter 41, And greatly affect the accuracy of subsequent surface quality detection. However, it can be seen from the actual implementation that the manual method of breaking the paper seriously has the disadvantages of low production efficiency, high labor intensity, and the inability to ensure the effect of breaking the paper, which greatly affects the authenticity rate.

It can be seen that it is imminent to design a paper breaking device that can automatically break paper for printed matter, and what needs to be considered is that the efficiency of breaking paper for a printed matter at a time is too low for the paper breaking device, and once for Too thick printed matter stacks have poor effect on paper breaking, so it is necessary to provide thinner printed matter stacks to the paper breaking equipment for paper breaking operation. From the actual implementation point of view, the labor intensity of the workers to continuously send the thinner print stacks to the paper breaking equipment is also very large. Therefore, a method is designed to divide the thicker print stacks into several thinner print stacks to reduce the labor of the workers. High-strength equipment is an urgent problem to be solved at present.

The working process of the present utility model is:

Facing the stacking paper loading mechanism 110, a thick printed product stack 200 of a set height stacked by workers on it is transported to the output plane formed by the short conveyor belt device 112, and when it stops in front of the in-position baffle 114, as shown in Figure 2 As shown in Fig. 3, the lifting bracket 122 is raised from the lower limit, and the thick printed matter pile 200 on the short conveyor belt 1121 will be stopped before the baffle plate 114 in place. When the top of the thick printed matter stack 200 was detected by the stack top detection sensor 123, the lifting bracket 122 stopped rising, and the splitting cylinder 124 drove the splitting top block 125 to stretch out obliquely upwards, so the splitting top block 125 pushed the thick printed matter One side of the upper part of the stack 200 is lifted at a certain angle, and a large gap appears between the lifted printed matter and the printed matter below, so the telescopic cylinder 126 drives the cardboard 121 to extend into this gap, and the lifted printed matter is held up, that is The thin printed matter stack 300 is disassembled, and then the lifting bracket 122 moves down for a short distance, and the paper support plate 121 holds the separated thin printed matter stack 300 and moves laterally above the input end of the small stack conveying mechanism 130, and then is conveyed by the small stack The mechanism 130 transports the stack of thin printed matter 300 to the paper breaking mechanism behind.

During the process of the paper support plate 121 moving above the input end of the small pile conveying mechanism 130, the paper support plate 121 passes through the entrance baffle plate 132 under the elastic downward pressure of the paper retaining wheel 138, and when the paper support plate 121 reaches the transverse output position , the telescopic cylinder 126 drives the cardboard 121 to withdraw, so that the stack of thin printed matter 300 falls on the input end of the small stack conveying mechanism 130 under the blocking of the entrance baffle plate 132 and the stopper wheel 138, and the transportation is completed. Then the paper support plate 121 returns to the horizontal initial position, and continues to stack the remaining printed matter stacks on the lifting bracket 122 by means of the stacking top block 125 .

When there are only a few prints left as the last stack of thin prints on the lifting bracket 122, the stack top detection sensor 123 no longer detects, and the lifting bracket 122 directly rises to the upper limit, and then the telescopic cylinder 126 drives the cardboard 121 to stretch into the upper limit. To the bottom of the lifting bracket 122, the lifting bracket 122 moves down for a certain distance, and the printed matter stack on it is transferred to the cardboard 121, so the cardboard 121 supports the last thin printed product stack 300 and moves laterally to the small stack conveying mechanism 130 Above the input end, send into the small pile conveying mechanism 130.

Then the lifting and destacking mechanism 120 continues to destack and output the next thick printed product stack 200, and the operation is repeated.

It should be noted that, in actual implementation, the number of stacks of thick printed matter stacks 200 can be set in advance. If it is set to divide a thick printed matter stack 200 into four thin printed matter stacks, then the first three thin printed matter stacks will be divided into four thin printed matter stacks. The stacking top block 125 is disassembled, and the last remaining printed matter is directly conveyed out as the last stack of thin printed matter.

What needs to be mentioned here is that the thick printed matter stack 200 is transported into the lifting and dividing mechanism 120 of the utility model along the width direction of the printed matter itself, and the lifting and dividing mechanism 120 of the utility model is to output the thin printed matter stack 300 along the length direction of the printed matter itself. Yes, the conversion of the printed matter stacks in the conveying direction is realized here, so that the equipment can be arranged perpendicular to each other instead of in a straight line, which greatly saves space.

The utility model has the advantages of:

The utility model can continuously disassemble the stack of thick printed matter into several stacks of thin printed matter, so as to facilitate the paper-breaking operation of folding and pressing out the stack of thin printed matter by the paper breaking mechanism at the back. The strength is small. The utility model is applicable to the stacking of various small sheets of paper printed matter such as hard small sheets of cigarette labels.

The above are the preferred embodiments of the utility model and the technical principles used therefor. For those skilled in the art, without departing from the spirit and scope of the utility model, any technical solution based on the utility model Obvious changes such as basic equivalent transformations and simple replacements all fall within the protection scope of the present utility model.
