In the present utility model, the stacking paper loading mechanism 110, the small stack conveying mechanism 130, and the paper loading conveying mechanism 150 may also have other configuration forms, which are not limited to the above. Each conveyor belt device in each mechanism of the present utility model is a well-known device in the art, and its specific structure is not described in detail here.

The working process of the utility model breaking off the paper loading machine 100 is:

As shown in Figure 3, the worker aligns one side of the thick printed matter stack 200 with a set height with the stacking baffle 113, puts it neatly and without gaps on the long conveyor belt 1111, and starts the long conveyor belt device 111 to run. When a stack of thick printed matter 200 arrives at the output end of the long conveyor belt device 111, it is detected by the input detection sensor. Because there is a speed difference between the long and short conveyor belt devices 111 and 112, two adjacent thick printed matter stacks 200 pass through the long conveyor belt device 111. , between the short conveyor belt devices 111 and 112, the gap is opened, so a thick printed matter stack 200 transported at the front is transported into the short conveyor belt device 112, the long conveyor belt device 111 stops running, and the thick printed matter stack 200 behind Each stack of thick printed matter stays on the long conveyor belt device 111, while the short conveyor belt device 112 continues to run until the stack of thick printed matter 200 is transported to the position baffle 114. At this time, it is detected by the position detection sensor, and the short conveyor belt is controlled. The belt device 112 stops running, that is, the task of conveying the thick printed matter stack 200 to the lifting and sorting mechanism 120 is completed, and then the lifting and sorting mechanism 120 implements the stacking operation for the thick printed matter stack 200 . After the thick printed matter stack 200 is input into the lifting and sorting mechanism 120 and all the stacking is completed, the long and short conveyor belt devices 111, 112 will transport the next thick printed matter stack 200 to the front of the baffle plate 114 in place, and the operation is repeated.

Then as shown in Fig. 4 and Fig. 5, at this time, the lifting bracket 122 rises from the lower limit position, and a thick printed product stack 200 on the short conveyor belt 1121 will be stopped before the in place baffle plate 114, and when the thick printed matter stack 200 stacks When the top is detected by the stack top detection sensor 123, the lifting bracket 122 stops rising, and the stacking cylinder 124 drives the stacking top block 125 to protrude obliquely upwards, so the stacking top block 125 pushes one side of the upper part of the thick printed matter stack 200. From a certain angle, there is a large gap 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 lifted up, that is, the thin printed matter stack 300 is split. , and then the lifting bracket 122 moves down a short distance, and the paper support plate 121 holds the separated thin printed matter stack 300 and moves laterally to the top of the input end of the small stack conveying mechanism 130 .

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 separating mechanism 120 along the width direction of the printed matter itself, and the lifting and separating mechanism 120 outputs the thin printed matter stack 300 along the length direction of the printed matter itself. The conversion of the printed matter stacks in the conveying direction allows the equipment to be arranged vertically instead of in a straight line, which greatly saves space.

After the thin printed matter stack 300 is sent into the small stack conveying mechanism 130, the thin printed matter stack 300 is sent to the unpowered roller 135 through the conveyor belt device, and the length of the roller conveying device along the thin printed matter stack conveying direction is greater than the length of the printed matter. When the printed matter stack 300 reaches the outlet baffle plate 136 and blocks it, it is detected by the paper push detection sensor 133, so the paper push cylinder 1340 drives the push cardboard 134 to move, and pushes the thin printed matter stack 300 to the front of the paper blocking narrow plate 137, and pushes against it in front of the paper blocking narrow plate 137. On the paper blocking narrow plate 137, the paper breaking mechanism 140 to be transported into the back.

It should also be mentioned here that the thin printed matter stack 300 is transported along the length direction of the printed matter itself on the small stack conveying mechanism 130, and when the small stack conveying mechanism 130 outputs the thin printed matter stack 300, it is output along the width direction of the printed matter itself. At the same time, the conversion of the printed matter stack in the conveying direction is realized, so that the equipment can be arranged perpendicular to each other instead of linear arrangement, which greatly saves space.

It should also be mentioned that the heights of the stacks of thick printed matter 200 received by the lifting and sorting mechanism 120 are the same, because they are stacked on the paper mechanism 110 by workers, while the stacks of thin printed matter 300 output by the lifting and sorting mechanism 120 The height and the number of sheets containing printed matter can be different, but they will all be within the height range of the stack of thin printed matter.

Next, as shown in Figures 6 to 13, the lifting cylinder 1412 drives the paper support bracket 1411 to rise, and a stack of thin printed matter 300 (stack A) that stops in front of the paper blocking narrow plate 137 is lifted on the first paper support station 161 , the lifting height is higher than the paper bracket 1422, and then the transposition cylinder 1413 drives the paper bracket 1411 and the lifting cylinder 1412 to move backward on the slide rail 1414 for a set distance, and then the lifting cylinder 1412 drives the paper bracket 1411 to descend , transfer the stack of thin prints 300 (stack A) on the first paper support station 161 to the first paper breaking station 171, and then the transposition cylinder 1413 drives the paper support bracket 1411 and the lift cylinder 1412 to return to the horizontal initial position together , waiting for the next stack of thin printed matter in front of the paper stop narrow plate 137 to be supported. At this time, the positioning cylinder 1452 drives the positioning block 1451 to withstand the two short sides of the thin printed matter stack 300 (stack A) on the first paper breaking station 171, and the thin printed matter stack 300 is positioned, and the paper breaking cylinder 1431 drives the paper breaking The support 1432 moves down against the top surface of the stack of thin printed matter 300 (stack A), so that the first and second pressing blocks 1424, 1423 on the paper breaking bracket 1422 of the first paper breaking station 171 and the paper breaking support 1432 The third and fourth pressing blocks 1434, 1433 of the thin print stack 300 cooperate with each other to press the two sides of the right-angled slit 504 of the printed matter in the thin printed matter stack 300, so that the right-angled slit 504 does not stick to the adjacent edge, that is, to fold the ear 505 Press out. After the paper breaking operation is completed, the paper breaking cylinder 1431 drives the paper breaking support 1432 to rise and retract, and the positioning cylinder 1452 drives the positioning block 1451 to retreat.

Then, similar to the above-mentioned process, the next thin print stack 300 (stack B) in front of the paper blocking narrow plate 137 is held up on the first paper support station 161 of the raised paper support bracket 1411, and is in the first position. The thin printed matter stack 300 (stack A) that has finished breaking the paper once on the paper station 171 is held up on the second paper support station 162 of the raised paper support bracket 1411, and then the paper support bracket 1411 After moving the set distance, it descends, and transfers the thin printed matter stack 300 (stack A) on the second paper supporting station 162 to the second paper breaking station 172, and at the same time, transfers the thin printed matter stack 300 (stack A) on the first paper supporting station 161 300 (stack B) is transferred to the first paper breaking station 171, and then the paper support bracket 1411 returns to the horizontal initial position, waiting for the next stack 300 of thin printed matter. At this time, the stack of thin printed matter 300 on the first and second paper breaking stations 171, 172 is positioned under the action of the positioning block 1451 to perform the paper breaking operation (the paper breaking process is the same as above, and will not be described here).

After the first and second paper breaking stations 171 and 172 have completed the paper breaking operation, the next stack of thin printed matter 300 (stack C) in front of the paper blocking narrow plate 137 is lifted on the raised paper support bracket 1411 On the first paper supporting station 161, the thin printed matter stack 300 (stack B) that is on the first paper breaking station 171 and has completed a paper breaking is held on the second support of the raised paper supporting bracket 1411 On the paper station 162, the thin printed matter stack 300 (stack A) that is on the second paper breaking station 172 and has finished breaking the paper twice is held up by the third paper supporter of the raised paper support bracket 1411. On the position 163, then the paper supporting bracket 1411 descends after translating the set distance, and the thin printed matter stack 300 (stack A) on the third paper supporting station 163 is transferred to the transition station 173 without any processing, and the second The stack of thin printed matter 300 (stack B) on the paper supporting station 162 is transferred to the second paper breaking station 172, and the paper is broken for the second time under the positioning of the positioning block 1451, and the first paper supporting station 161 is placed The stack of thin printed matter 300 (stack C) is transferred to the first paper breaking station 171, and the paper is broken for the first time under the positioning of the positioning block 1451, while the paper support bracket 1411 returns to the horizontal initial position, waiting for the next thin printed matter Stack 300.

Next, the next stack of thin printed matter 300 (stack D) in front of the paper blocking narrow plate 137 is held up on the first paper support station 161 of the raised paper support bracket 1411, and is on the first paper breaking station 171 The thin printed matter stack 300 (stack C) that has completed a paper break is held up on the second paper support station 162 of the raised paper support bracket 1411, and the thin printed matter stack 300 (stack C) that is on the second paper break station 172 is held up on the raised paper support bracket 1411.

The stack of thin prints 300 (stack D) on the first paper support station 161 is transferred to the first paper breaking station 171, and the paper is broken for the first time under the positioning of the positioning block 1451, while the paper support bracket 1411 returns to the horizontal initial position. position, waiting for the next thin print stack 300. Wherein, when performing paper release, the paper release cylinder 1442 drives one side of the paper release frame 1441 to move downward (the other side of the paper release frame 1441 close to the transition station 173 does not move), and the paper release frame 1441 is formed by a horizontal rectangular horizontal frame. The cross-section becomes a non-horizontal parallelogram cross-section, that is, a vertical paper movement is implemented on the thin printed matter stack 300, and the printed matter that has been compacted by breaking the paper is loosened to achieve the effect of loosening the paper and avoiding the upper and lower printed matter. Check the paper jam failure of the paper feeding mechanism 10 of the product machine to ensure smooth paper feeding.

Next, the next stack of thin prints 300 (stack E) before the paper blocking narrow plate 137 is held up on the first paper support station 161 of the raised paper support bracket 1411, and is on the first paper breaking station 171 The thin printed matter stack 300 (stack D) that has completed a paper break is held up on the second paper support station 162 of the raised paper support bracket 1411.

Then repeat as above.

That is to say, in the process of passing through the paper breaking mechanism 140, a stack of thin printed matter 300 will successively go through a paper breaking on the first paper breaking station 171 and another paper breaking on the second paper breaking station 172. , The transition stagnation on the transition station 173 and the loose paper on the loose paper station 181 are then sent out.

It should be mentioned that when performing the paper breaking operation, take the first paper breaking station 171 as an example, if the two first pressing blocks 1424 and the two second pressing blocks 1423 on the first paper breaking station 171 If the parts indicated by the labels A2 and B2 shown in Figure 17 are respectively pressed, then the two third pressing blocks 1434 and the two fourth pressing blocks on the upper paper breaking support 1432 corresponding to the first paper breaking station 171 1433 respectively presses the parts indicated by the labels A1 and B1 shown in FIG. The two sides of the right-angled slit 504 realize one up and one down dislocation pressing, so that the right-angled slit 504 can be completely pressed out, that is, the folded ear 505 can be pressed out.

Then as shown in Fig. 14 and Fig. 15, when the thin printed matter stack 300 conveyed from the paper loosening station 181 falls on the connecting conveyor belt 1511, the power shaft 1524 runs for a set time to transport the thin printed matter stack 300 forward for a small distance, The above-mentioned process is repeated, and the stacks of thin printed matter 300 that are transported out are transported to the telescopic conveyor belt 1521 at a short distance apart in sequence. When a stack of thin printed matter 300 reaches the motion sensor 155 and is detected by it, the telescoping conveyor belt 1521 stops running. When the height of the printed product stack 40 input to the paper feeding mechanism 10 is lower than the limit sensor 157, the telescopic belt cylinder 1531 drives the telescopic member to stretch out to stop when it is detected by the stretch detection sensor 156, and then quickly retracts to the original position, so The stack of thin printed matter 300 detected by the motion sensor 155 just now is sent into the input end of the paper feeding mechanism 10, and lands on the top of a stack of printed matter stacks 40 at the input end of the paper feeding mechanism 10 to realize the paper feeding operation to the paper feeding mechanism 10. . Repeat this operation.

It should be mentioned that during the stretching and retracting of the telescopic member, since the connecting plate 1532 and the two fixed shafts 1533, 1534 are integrated, the center distance between the two fixed shafts 1533, 1534 is two The sum of the radii of the fixed shafts plus the thickness of the telescopic conveyor belt 1521, therefore, when the telescopic belt cylinder 1531 stretches out and retracts, the total length of the telescopic conveyor belt 1521 can remain unchanged without affecting the tightness of the telescopic conveyor belt 1521.
