Description

Technical Field

[0001] The utility model relates to the technical field of book processing, in particular to a loose-leaf book stacking mechanism. Background Art

[0002] The book production process mainly includes plate making, printing, binding, packaging and palletizing. After the packaged books are stacked together, they need to be palletized so that the books can be stored or transported to a designated location. Among them, the existing book palletizing equipment is as follows:

[0003] A Chinese patent document with publication number CN219135686U discloses a book unloading equipment with integrated conveying, clamping and stacking, which specifically discloses: it includes a front stacking mechanism for book unloading, a clamping and transferring mechanism and a stacking and conveying mechanism; the front stacking mechanism includes a conveying platform and a stacking platform, so that multiple piles of books can be provided to the clamping and transferring mechanism more neatly, thereby improving the neatness, and will not collapse and fall during subsequent stacking, thereby increasing the height of the stacking; the clamping and transferring mechanism includes a transfer clamp installed at the execution end of a multi-axis robot, which can clamp multiple books at the same time and transfer them to a book stacking unit, with a large transfer capacity, which can meet the needs of large-scale book transfer and stacking; the transfer seat is also equipped with a suction cup assembly that can be raised and lowered. After the book is located on the book stacking unit, the separation paper can be sucked and covered on the surface of the book by the suction cup assembly, and two adjacent layers of books in the stacking area can be separated by the separation paper, thereby effectively protecting the books.

[0004] As can be seen from the above, the existing palletizing equipment first transports multiple piles of books through a conveying platform, thereby transporting multiple piles of books to a stacking platform for stacking, and then clamps and transports multiple books through a clamping and transferring mechanism installed on a multi-axis robot to transport multiple books to a designated location, thereby realizing new palletizing. However, after the existing palletizing equipment stacks the books, the neatness of the books is not high. When the conveying platform transports multiple piles of books, there may be gaps between the books for air circulation, so the books may shift during the transportation process; and when the stacking platform stacks the books, it will cause wear on the bottom of the first pile of books, resulting in poor palletizing effect. Therefore, a loose-leaf book stacking mechanism is provided to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following is a detailed description of a loose-leaf book stacking mechanism of the present invention in conjunction with the accompanying drawings.

[0032] like Figure 1-2As shown, an embodiment of a loose-leaf book stacking mechanism of the utility model comprises a first bracket 1 and a second bracket 2 disposed beside the first bracket 1, wherein a transport component 3 for continuously transporting a book stack is provided on the first bracket 1, and a conveying assembly connected to the transport component 3 is provided on the second bracket 2, and the conveying assembly is used to transport at least one book stack to a designated transport position; the book stack is first transported to the conveying assembly by the transport component 3, and then the position of the book stack is adjusted by the conveying assembly, and after the adjustment, the book stack can be transported. Specifically, the conveying assembly includes a first conveying mechanism 8 and a second conveying mechanism 81 connected thereto, and the first conveying mechanism 8 and the second conveying mechanism 81 have the same structure. When the transport component 3 transports the first stack of books to the first conveying mechanism 8, the first conveying mechanism 8 transports the first stack of books to the second conveying mechanism 81, and then adjusts the position of the first stack of books through the second conveying mechanism 81, so that the first stack of books is placed at a designated transport position. Subsequently, the transport component 3 transports the second stack of books to the first conveying mechanism 8, and adjusts the second stack of books through the first conveying mechanism 8, so that the second stack of books is placed at a designated transport position, so as to facilitate the simultaneous transport of the first stack of books and the second stack of books to the designated stacking position; after the transport is completed, the transport component 3 continues to transport the books to the first conveying mechanism 8 and the second conveying mechanism 81, so as to realize the stacking of the books; and the first conveying mechanism 8 and the second conveying mechanism 81 are used to transport and adjust the books to prevent wear on the bottom of the books.

[0033] In order to solve the problem that the book stack may deviate during transportation, an exhaust mechanism 4 placed above the transport component 3 and a pair of sorting mechanisms placed on both sides of the transport component 3 are sequentially arranged on the first bracket 1 along the transport direction of the book stack. A straightening mechanism 5 used in conjunction with the sorting mechanism is also provided on the first bracket 1 to straighten the book stack. When the book stack is transported to the bottom of the exhaust mechanism 4 by the transport component 3, the transport component 3 stops running, and then the exhaust mechanism 4 is operated to squeeze the book stack downward, thereby squeezing out the air inside the book stack, and preventing air from flowing in the gaps in the book stack, causing the book stack to deviate during transportation; after the squeezing is completed, the exhaust mechanism 4 is reset, and then the transport component 3 is started again to transport the exhausted book stack to between the sorting mechanisms, and the next stack of books is placed just below the exhaust mechanism 4, and the exhaust mechanism 4, the sorting mechanism and the straightening mechanism 5 are operated at the same time to exhaust and straighten the book stack. After the book stack is straightened, the transport component 3 transports the book stack to the first conveying mechanism 8, and the book stack is transported to the designated handling position.

[0034] In addition, the stacking mechanism also includes a base 11 and a multi-axis robot 12 mounted on the base 11. A gripping mechanism 13 for gripping multiple book stacks is provided on the execution end of the multi-axis robot 12, and a plurality of book stack placement boards 14 are provided on the side of the base 11. After the book stack is transported to the designated transport position by the first conveying mechanism 8 and the second conveying mechanism 81, the multi-axis robot 12 is operated to place the gripping mechanism 13 at the book stack, and then the gripping mechanism 13 is operated to grip the book stack placed at the transport position. The multi-axis robot 12 moves with the gripping mechanism 13 to place multiple book stacks on the book stack placement board 14, thereby realizing the stacking process of the book stack. Furthermore, a lifting mechanism 9 for lifting the book stack placed at the designated position is provided on the second bracket 2. Before the gripping mechanism 13 grips the book stack, the lifting mechanism 9 is operated to lift multiple book stacks at the same time, thereby facilitating the gripping mechanism 13 to grip the book stack and improving the handling efficiency. Additionally, a limiting plate 10 for limiting the position of the book stack is provided beside the second conveying mechanism 81. With the cooperation of the limiting plate 10 and the second conveying mechanism 81, the stacked books can be positioned and the book stack can be adjusted to a designated position.

[0035] like Figure 2 As shown, the arranging mechanism includes a fourth cylinder 6 mounted on the first bracket 1 and a push plate 7 fixedly mounted on the end of the telescopic rod of the fourth cylinder 6. When the exhausted book stack is transported between the push plates 7 on both sides by the transport component 3, the fourth cylinders 6 on both sides are simultaneously started, thereby pushing the push plates 7 on both sides to move in a direction close to each other, so as to straighten the book stack. In addition, the position of the fourth cylinder 6 on the first bracket 1 is adjustable, so as to realize straightening of book stacks of different sizes.

[0036] like Figure 3-4 As shown, the exhaust mechanism 4 includes a support frame 401 fixedly mounted on the first bracket 1 and a first cylinder 402 mounted on the support frame 401. The first cylinder 402 is placed above the transport component 3 and the telescopic rod is arranged downward. A pressing plate 404 for squeezing the book stack is mounted on the end of the telescopic rod of the first cylinder 402 through a first mounting plate 403. When the book stack is transported to the bottom of the pressing plate 404, the first cylinder 402 is started to drive the pressing plate 404 to move downward, thereby squeezing out the air inside the book stack and preventing air from flowing in the gaps in the book stack, causing the book stack to shift during transportation. In addition, a vertically arranged first guide rod 405 is fixedly mounted on the first mounting plate 403, and the first guide rod 405 is slidably arranged with the support frame 401. Under the action of the first guide rod 405, the pressing plate 404 can stably move up and down.

[0037] The straightening mechanism 5 includes a support plate 501 fixedly arranged on the first bracket 1 and placed under the transport component 3, a guide rail 502 whose length direction is parallel to the transport direction of the transport component 3 is fixedly arranged on the support plate 501, and a slide plate 503 is slidably arranged on the guide rail 502, and the slide plate 503 slides on the guide rail 502 along the transport direction of the transport component 3; in order to realize the automatic sliding of the slide plate 503, a second cylinder 504 is installed on the support plate 501, and the end of the telescopic rod of the second cylinder 504 is fixedly arranged on the slide plate 503, and the slide plate 503 is driven to slide on the guide rail 502 by the second cylinder 504. The straightening mechanism 5 further comprises a pair of straightening parts respectively arranged on the slide plate 503 and the support plate 501. The straightening parts arranged on the slide plate 503 and the straightening parts arranged on the support plate 501 operate simultaneously to be placed at the front and rear sides of the book stack, and the push plate 7 is placed at the left and right sides of the book stack. Then, the second cylinder 504 is started to push the straightening parts arranged on the slide plate 503 to move in the direction close to the book stack, thereby pushing the book stack to be straightened. The straightening parts at the front and rear sides of the book stack and the push plates 7 at the left and right sides cooperate to fully straighten the book stack, so that the stacked books can be neatly placed.

[0038] Furthermore, the straightening part arranged on the slide plate 503 includes a third cylinder 505 with a telescopic rod arranged upward and a lifting plate 506 fixed on the end of the telescopic rod. A pair of vertically arranged push rods 507 are fixed on the lifting plate 506. The push rods 507 can pass through the top of the first bracket 1 and are used to push the book stack to straighten. When the third cylinder 505 is started, the push rod 507 is driven to move upward, so as to pass through the top of the first bracket 1 to be placed on the side of the book stack, and then the second cylinder 504 is started to push the push rod 507 to move, so as to push the book to be straightened. In addition, a vertically arranged second guide rod 508 is fixed on the lifting plate 506, and the second guide rod 508 is slidably arranged with the slide plate 503. Under the action of the second guide rod 508, the push rod 507 can stably move up and down.

[0039] like Figure 5-6As shown, the lifting mechanism 9 includes a fixed plate 901 arranged on the second bracket 2, and the fixed plate 901 is placed below the first conveying mechanism 8 or the second conveying mechanism 81. A fifth cylinder 902 with a telescopic rod arranged upward is installed on the fixed plate 901, and a connecting plate 903 is fixed on the end of the telescopic rod. A plurality of ejector rods 905 for simultaneously lifting the book stacks placed on the first conveying mechanism 8 and the second conveying mechanism 81 are installed on the connecting plate 903. After the multiple book stacks are lifted by the ejector rods 905, the bottom of the book stack is separated from the first conveying mechanism 8 and the second conveying mechanism 81, so that the clamping mechanism 13 can clamp the multiple book stacks. In addition, a third guide rod 904 arranged vertically is fixed on the connecting plate 903, and the third guide rod 904 is slidably arranged with the fixed plate 901.

[0040] Furthermore, the first conveying mechanism 8 includes a pair of rotating shafts 801 arranged on the second bracket 2, the rotating shafts 801 are arranged horizontally and the axial direction is perpendicular to the conveying direction of the book stack, and a plurality of conveying wheels 802 of the same number are respectively arranged on each rotating shaft 801, and a conveying belt 803 for adjusting the position of the book stack is wound around the corresponding conveying wheels 802 on both sides; the conveying speed of the transport component 3 is the same as the speed of the conveying belt 803, and the rotating shaft 801 is driven to rotate to adjust the position of the book stack placed on the conveying belt 803. In addition, in order to drive the rotating shaft 801 to rotate, a driving motor 806 is installed on the second bracket 2 through a mounting frame 805, and a transmission wheel 807 is arranged on the output shaft of the driving motor 806 and the rotating shaft 801, and a transmission belt 808 for transmitting power to the rotating shaft 801 is wound around the transmission wheel 807. A bracket 804 for supporting the conveyor belt 803 is provided between the conveyor wheels 802 on both sides. The bracket 804 prevents the conveyor belt 803 from being deformed due to the weight of the book stack itself, thereby preventing the accuracy of adjusting the position of the book stack from being affected.

[0041] like Figure 7-8As shown, the clamping mechanism 13 includes a connecting seat 131 fixedly arranged on the execution end of the multi-axis robot 12, wherein an "L"-shaped support frame 132 is slidably provided on the connecting seat 131 up and down, and a material picking fork 136 and a horizontally arranged fourth guide rod 134 are provided in the support frame 132, and the material picking fork 136 is slidably arranged on the fourth guide rod 134 through a slider 135, so that the material picking fork 136 can slide in and out on the support frame 132; however, in order to realize that the material picking fork 136 can move automatically, a screw rod 137 is provided in the support frame 132, and the axial direction of the screw rod 137 is parallel to the axial direction of the fourth guide rod 134, and a fixing block 138 is provided on the material picking fork 136, and the fixing block 138 is threadedly connected to the screw rod 137. When the screw rod 137 is driven to rotate, the material picking fork 136 is driven to slide in and out on the support frame 132 under the action of the fixing block 138. Specifically, after the position of the book stack is adjusted, the fifth cylinder 902 is started to drive the push rod 905 to move upward, and at the same time, the multiple book stacks are lifted up, and the bottom of the book stacks are separated from the first conveying mechanism 8 and the second conveying mechanism 81. Then, the multi-axis robot 12 is operated to carry the support frame 132 and place it beside the multiple book stacks. The screw rod 137 is driven to rotate to drive the material fork 136 to slide out and be placed at the bottom of the multiple book stacks, and the material fork 136 passes between several push rods 905. Finally, the multi-axis robot 12 is controlled to move with the support frame 132 to realize the transportation and processing of the multiple book stacks.

[0042] However, in order to enable the multi-axis robot 12 to stably carry the book stack, a pair of sixth cylinders 1310 are installed on the outer side of the support frame 132 through the second mounting plate 139. The telescopic rod of the sixth cylinder 1310 is arranged downward and a clamping plate 1311 for clamping the multiple book stacks is fixed on its end. When the material picking fork 136 is placed at the bottom of the multiple book stacks, the sixth cylinder 1310 is started to push the clamping plate 1311 downward to clamp the multiple book stacks with the cooperation of the material picking fork 136, so that the book stack will not fall during the process of carrying the book stack. After the book stack is carried to the book stack placement plate 14, the material picking fork 136 is first controlled to reset, and then the clamping plate 1311 is controlled to reset, so as to realize the stacking of the book stack. Additionally, a spring 133 is provided between the connecting seat 131 and the supporting frame 132. Under the action of the spring 133, a buffer distance is provided between the supporting frame 132 and the multi-axis robot 12 to prevent the book stack from being crushed when the book stack is placed, thereby improving the stacking effect.

[0043] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
