Description

Technical Field

[0001] This invention belongs to the field of book stacking technology, and particularly relates to a book feeding and stacking device. Background Technology

[0002] During and after processing, books need to be stacked for storage and transfer to the next processing unit.

[0003] Referring to the book unloading and palletizing mechanism described in patent application CN116853833A, the mechanism includes an unloading conveying mechanism and a palletizing robot. The palletizing robot is equipped with an unloading fixture, which includes an openable clamping block. The clamping block is equipped with a book-pressing component and a support component. The book-pressing component elastically presses the book, and the support component can be flipped to support the book and allow it to be unloaded. After the book is conveyed to a designated position by the unloading conveying mechanism, the unloading fixture moves to align with the book. The unloading fixture descends to clamp the book, the book-pressing component presses down against the top of the book, and then the support component flips to support the book. The book is clamped from both sides by the book-pressing component and the support component. After the unloading fixture moves to a designated position, the support component flips, allowing the book to fall between the two clamping blocks. This eliminates the need for clamping blocks to hold the book, reduces friction during unloading, effectively protects the book, and provides more stable clamping, preventing the book from falling.

[0004] After books are processed, they are easily squeezed and scratched during transfer, stacking, and unstacking. For example, the above-mentioned technical means reduce friction on the books by skipping the clamping operation. However, friction between books and friction scratches between books in the stacking box will still occur during stacking and unstacking. In addition, new books will stick together after long-term stacking, and books will fold during unstacking, which will affect the appearance of the books and even affect sales. In order to avoid the above situations, a book unloading and stacking device is provided. Summary of the Invention

[0005] This invention provides a book stacking and palletizing device, which aims to solve the problems that occur during the transfer, stacking, and unstacking of books after processing, such as friction between books and friction scratches between books in the stacking box shell. Furthermore, new books may stick together after long-term stacking, and books may fold during unstacking, thus affecting the appearance of the books and even their resale value.

[0006] The present invention is implemented as follows: a book palletizing and stacking device includes a main frame and an inner sliding transfer assembly: a heat shrink assembly is provided on the inner wall of the main frame, a plastic coating assembly is fixedly connected to the inner wall of the main frame, a rear conveying assembly is fixedly connected to the inner wall of the main frame, an outer sliding transfer assembly is provided on the inner wall of the main frame, a pick-and-place assembly is fixedly connected to the outer wall of the main frame, and a front conveying assembly is fixedly connected to the top of the main frame;

[0007] The plastic coating assembly includes a first lifting hydraulic cylinder, an upper winding bracket, and a lower winding bracket, all fixedly mounted on the outer wall of the main frame. A heat-shrinkable film is fixedly connected to one end of the first lifting hydraulic cylinder. The outer walls of both the upper and lower winding brackets are equipped with a film-retracting motor and a film-releasing motor, with a lower heat-shrinkable film and an upper heat-shrinkable film connected between them. During use, after the book in the current conveyor assembly is transferred to the outer conveyor belt in the subsequent conveyor assembly and is placed on the lower heat-shrinkable film, the first lifting hydraulic cylinder is controlled to press the heat-shrinkable film downwards. The heating resistance wires in the heat-shrinkable film frame are then activated to heat-press and bond the upper and lower heat-shrinkable films of the book together, completing the plastic coating of the book. This, combined with the outer conveyor belt, allows the book to be conveyed to the conveyor rollers for heat-shrinking and tight wrapping.

[0008] Preferably, the interior of the hot cutting frame is hollowed out, and electric heating resistance wires are embedded around the bottom of the hot cutting frame;

[0009] The film taking-up motor and the film releasing motor are both two in number, and the output shafts of the film taking-up motor and the film releasing motor are fixedly connected to the film taking-up shaft via a coupling. The outer walls of the film taking-up shaft are fixedly connected to the two ends of the lower heat shrink film and the upper heat shrink film, respectively.

[0010] Preferably, the rear conveying assembly includes a first bracket and a second bracket fixedly mounted on the main frame;

[0011] The inner wall of the first hanger is provided with an outer conveyor belt;

[0012] The inner wall of the second hanging frame is equipped with two side frame plates. The outer wall of the side frame plates is fixedly connected to two small drive motors, and the inner wall of each side frame plate is embedded with two transmission gears. The outer wall of the transmission gears is meshed with a chain, and the outer wall of the chain is fixedly connected to several transmission rollers. The output shaft of the small drive motor is fixedly connected to the outer wall of the transmission gear through a coupling. Through the setting of the rear transmission assembly, plastic coating, heat shrinking, and conveying can be realized: the books in the current transmission assembly are conveyed to the outer conveyor belt in the rear transmission assembly and after being plastic coated by the plastic coating assembly, they are then conveyed by the outer conveyor belt to several transmission rollers. After that, by starting and controlling the small drive motors, the transmission gears are driven to rotate, which in turn drives the several transmission rollers on the chain to slide the heat-shrink coated books inward to the directional conveying assembly.

[0013] Preferably, the heat shrink assembly includes a side frame fixedly mounted on the main frame base. A hot air blower is provided at the bottom of the side frame. There are multiple hot air blowers, which are respectively located at the bottom of the side frame and between two side frame plates in the rear conveyor assembly. Through the setting of the heat shrink assembly and its use in conjunction with the rear conveyor assembly, the books in the current conveyor assembly are conveyed to the outer conveyor belt in the rear conveyor assembly and coated by the plastic coating assembly. After being conveyed by the outer conveyor belt to several conveyor rollers, the hot air blowers at the upper and lower ends are activated to blow air onto the outer wall of the coated book, thereby shrinking the heat shrink film and tightly wrapping the book.

[0014] Preferably, the front conveying assembly includes an upper hanging plate fixedly mounted on the main frame base, a second lifting hydraulic cylinder fixedly connected to the bottom of the upper hanging plate, a connecting seat fixedly connected to one end of the second lifting hydraulic cylinder, a sliding bracket inserted into the inner wall of the connecting seat, two storage frames fixedly connected to the bottom of the sliding bracket, an inner conveyor belt embedded in the lower inner wall of the storage frames, and a pressing mechanism embedded in the upper inner wall of the storage frames.

[0015] Among them, the upper and lower ends of the two storage boxes are fixedly connected to each other with mating seats, and the mating seats on the two storage boxes are mutually mating and slidingly connected. A first tensioning hydraulic cylinder is connected between each set of mutually mating and slidingly connected mating seats.

[0016] Preferably, the pressing mechanism includes an inner sliding frame slidably connected to the inner wall of the storage frame, and a telescopic pressing hydraulic cylinder is connected between the inner sliding frame and the storage frame. Several pressing wheels are movably connected to the bottom inner wall of the inner sliding frame, and the outer wall of the pressing wheels has corrugated grooves. With the setting of the front conveyor assembly, in use, firstly, according to the size of the books to be stacked, the first tensioning hydraulic cylinder is controlled to pull and adjust the position between the two storage frames, and the bound books are placed into the two storage frames. The telescopic pressing hydraulic cylinder is controlled to press down the pressing wheels to press the upper sides of the books, so that the four corners of the books are aligned, reducing the warping of the book edges. The second lifting hydraulic cylinder is controlled to lower the height of the storage frame, and books continue to be stacked in the storage frame. When several identical books or a set of books are stacked in the storage frame, the inner conveyor belt is started to transport them to one side of the rear conveyor assembly.

[0017] Preferably, the inner sliding transfer assembly includes an inner slide rail seat, the outer wall of which is slidably connected to a drive mechanism, the top of which is fixedly connected to a lifting and feeding hydraulic cylinder, the top of which is fixedly connected to a rotary feeding motor, the output shaft of which is fixedly connected to a feeding disc via a coupling, the top of which is provided with a positioning groove, and the inner wall of which is movably connected to several rollers;

[0018] The drive mechanism includes a T-shaped slide block that slides and engages with the inner slide rail. A drive motor and pulleys are located on both sides of the T-shaped slide block, and the drive motor and pulleys are connected by a transmission rod. Through the inner sliding transfer assembly, in use, the palletizing isolation seat is inserted onto the roller along the positioning groove. The rotational feeding motor is started and controlled to adjust the direction of the palletizing isolation seat for storing books. When the plastic-coated books are fed into the palletizing isolation seat along the rear conveyor assembly, the drive motor in the drive mechanism is started, causing the transfer assembly to slide outwards along the inner slide rail. The system moves the palletizing isolation seats and the books in them, in conjunction with the pick-and-place components, to the outer sliding transfer components, reducing manual intervention and improving transfer and palletizing efficiency. When books are placed in the palletizing isolation seats, both gravity and frictional resistance increase. The arrangement of several rollers between the palletizing isolation seats and the feeding tray reduces the frictional resistance between them, thus facilitating the movement and pick-and-place of the palletizing isolation seats. The lifting and feeding hydraulic cylinders can adjust the height of the palletizing isolation seats to allow for stacking and placing of the palletizing isolation seats on the outer sliding transfer components.

[0019] Preferably, the external sliding transfer assembly includes an external slide rail fixedly mounted on the main frame base. A stacking seat is slidably connected to the outer wall of the external slide rail, and several stacking isolation seats are sequentially inserted into the inner wall of the stacking seat. The top of each stacking isolation seat has several anti-slip textures. The external sliding transfer assembly is used in conjunction with the pick-and-place assembly and the internal sliding transfer assembly. The height of the stacking isolation seats and the electric suction cup on the feeding tray is adjusted by controlling the lifting and feeding hydraulic cylinder and the third lifting hydraulic cylinder, ensuring they are level and that the stacking isolation seats on the feeding tray are positioned at the top of the stacking seat or the uppermost stacking isolation seat. The movement is controlled by manipulating the pulling hydraulic cylinder. The electric suction cup, once attached to the outer wall of the palletizing isolation seat on the feeding tray, is activated for suction. The suction cup is then manipulated to pick up the palletizing isolation seat from the feeding tray and move it above the palletizing base for stacking. The anti-slip texture increases the frictional resistance between the inner wall of the palletizing isolation seat and the heat-shrink film covering the outer wall of the book, thus achieving a better anti-slip effect. The palletizing isolation seat also protects and isolates the outer wall of the book, preventing ink stains from sticking to the paper due to excessive pressure on the bottom books when stacked in high layers. Furthermore, stacking several palletizing isolation seats makes it easier for users to disassemble and retrieve books.

[0020] Preferably, the pick-and-place assembly includes a third lifting hydraulic cylinder fixedly mounted on the main frame base. A corner seat is fixedly connected to the top of the third lifting hydraulic cylinder, and two pulling hydraulic cylinders are fixedly connected to the inner wall of the corner seat. An electric suction cup is fixedly connected to the inner wall of the pulling hydraulic cylinder. Through the arrangement of the pick-and-place assembly, the electric suction cup is activated by controlling the movement of the pulling hydraulic cylinder. When the electric suction cup adheres to the outer wall of the palletizing isolation seat on the feeding tray, it is activated to perform adsorption. Then, the electric suction cup is manipulated to pick up the palletizing isolation seat on the feeding tray and move it above the palletizing seat for palletizing.

[0021] Compared with the prior art, the embodiments of this application have the following main advantages:

[0022] With the plastic wrapping component in place, during use, after the book in the current conveyor component is conveyed to the outer conveyor belt in the rear conveyor component and is placed on the lower heat shrink film, the first lifting hydraulic cylinder is controlled to press the hot cutting frame downwards and activate the heating resistance line in the hot cutting frame to heat-press and bond the upper and lower heat shrink films of the book together, thus completing the plastic wrapping of the book. In conjunction with the outer conveyor belt, the book is conveyed to the conveyor roller for thermoplastic tight wrapping.

[0023] The rear conveyor assembly enables plastic wrapping, heat shrinking, and conveying of books: books in the current conveyor assembly are conveyed to the outer conveyor belt in the rear conveyor assembly, plastic wrapped by the plastic wrapping assembly, and then conveyed by the outer conveyor belt to several conveyor rollers. By starting and controlling the small drive motor, the conveyor gears are rotated, which in turn drive the several conveyor rollers on the chain to slide the heat-shrink wrapped books inward onto the directional conveyor assembly.

[0024] By setting up the heat shrinking component and using it in conjunction with the rear conveyor component, the books in the current conveyor component are conveyed to the outer conveyor belt in the rear conveyor component and then wrapped by the plastic wrapping component. After being conveyed by the outer conveyor belt to several conveyor rollers, the hot air blowers at the top and bottom are activated to blow air onto the outer wall of the plastic-wrapped book, thereby shrinking the heat shrink film and wrapping the book tightly.

[0025] With the setup of the front conveyor component, during use, firstly, according to the size of the books to be stacked, the first tensioning hydraulic cylinder is used to pull and adjust the position between the two storage frames, and the bound books are placed into the two storage frames. The telescopic pressing hydraulic cylinder is controlled to press down the pressing roller to press the upper sides of the books, so that the four corners of the books are aligned and the warping of the book edges is reduced. The second lifting hydraulic cylinder is controlled to lower the height of the storage frames and continue to stack books into the storage frames. When several identical books or a set of books are stacked in the storage frames, the inner conveyor belt is started to transport them to one side of the rear conveyor component.

[0026] By using the inner sliding transfer assembly, the palletizing isolation seat is inserted into the roller along the positioning groove during use. The rotational feeding motor is started and controlled to select and adjust the direction of the palletizing isolation seat for storing books. After the books with plastic wrapping are fed into the palletizing isolation seat along the rear conveyor assembly, the drive motor in the drive mechanism is started to move the palletizing isolation seat and the books in the palletizing isolation seat outward along the inner slide rail. This works in conjunction with the pick-and-place assembly to move the palletizing isolation seat and the books in the palletizing isolation seat onto the outer sliding transfer assembly, reducing manual intervention and improving transfer and palletizing efficiency. When the books are placed in the palletizing isolation seat, the gravity and frictional resistance increase. The arrangement of several rollers and the palletizing isolation seat reduces the frictional resistance between the feeding tray and the palletizing isolation seat, thus facilitating the movement and pick-and-place of the palletizing isolation seat. The lifting feeding hydraulic cylinder can adjust the height of the palletizing isolation seat to stack the books and the palletizing isolation seat on the outer sliding transfer assembly.

[0027] The external sliding transfer component is used in conjunction with the pick-and-place component and the internal sliding transfer component. The height of the palletizing isolation seat and the electric suction cup on the feeding tray are adjusted by controlling the lifting and feeding hydraulic cylinder and the third lifting hydraulic cylinder, ensuring they are level. The palletizing isolation seat on the feeding tray is positioned at the top of the palletizing base or the uppermost palletizing isolation seat. The electric suction cup is moved by controlling the pulling hydraulic cylinder. Once the electric suction cup is against the outer wall of the palletizing isolation seat on the feeding tray, it is activated for suction. Then, the electric suction cup is operated... The tray picks up the palletizing isolation seat from the feeding tray and moves it above the palletizing seat for palletizing. The anti-slip texture increases the frictional resistance between the inner wall of the palletizing isolation seat and the heat-shrink film covering the outer wall of the book, thus achieving a better anti-slip effect. The palletizing isolation seat also protects and isolates the outer wall of the book, preventing ink stains from sticking to the paper when the bottom of the book is subjected to excessive pressure due to the high number of books stacked directly. Furthermore, stacking several palletizing isolation seats also makes it convenient for users to disassemble and retrieve the books. Attached Figure Description

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] This invention provides a book stacking and palletizing device, including a main frame 1 and an inner sliding transfer assembly 7: a heat shrink assembly 3 is provided on the inner wall of the main frame 1, a plastic coating assembly 2 is fixedly connected to the inner wall of the main frame 1, a rear conveying assembly 4 is fixedly connected to the inner wall of the main frame 1, an outer sliding transfer assembly 8 is provided on the inner wall of the main frame 1, a pick-and-place assembly 6 is fixedly connected to the outer wall of the main frame 1, and a front conveying assembly 5 is fixedly connected to the top of the main frame 1;

[0042] The plastic coating component 2 includes a first lifting hydraulic cylinder 201, an upper winding bracket 202, and a lower winding bracket 203, which are fixedly installed on the outer wall of the main frame 1. One end of the first lifting hydraulic cylinder 201 is fixedly connected to a hot cutting frame 208. The outer walls of the upper winding bracket 202 and the lower winding bracket 203 are each provided with a film winding motor 204 and a film unwinding motor 205, and a lower heat shrink film 207 and an upper heat shrink film 206 are connected between the film winding motor 204 and the film unwinding motor 205.

[0043] The interior of the hot cutting frame 208 is hollow, and electric heating resistance wires are embedded around the bottom of the hot cutting frame 208.

[0044] There are two film take-up motors 204 and two film release motors 205. The output shafts of the film take-up motors 204 and 205 are fixedly connected to the take-up and release shafts through couplings. The outer walls of the take-up and release shafts are fixedly connected to the two ends of the lower heat shrink film 207 and the upper heat shrink film 206, respectively.

[0045] It should be noted that after the books have been processed, during the transfer and stacking process, as well as during unpacking, there will be friction between the books and scratches caused by friction between the books in the stacking box. In addition, after a long period of stacking, new books may stick together, and unpacking may also result in folding of the books, which will affect the appearance of the books and even affect their sale.

[0046] Specifically, in this embodiment, the solution mainly utilizes the main frame 1, inner sliding transfer assembly 7, main frame 1, heat shrink assembly 3, plastic coating assembly 2, rear conveyor assembly 4, outer sliding transfer assembly 8, pick-and-place assembly 6, and front conveyor assembly 5 in their setup and coordinated use. In operation: First, based on the size of the books to be stacked, the first tensioning hydraulic cylinder 508 is used to adjust the position between the two storage frames 505, and the bound books are placed into the two storage frames 505. The telescopic pressing hydraulic cylinder 5061 is then controlled to press down the pressing roller 5063 to press the upper sides of the books, making the four corners of the books flush and reducing warping. The second lifting hydraulic cylinder 502 is then controlled to lower the height of the storage frames 505, continuing to push the books into the storage frames 505. When several identical books or a set of books are stacked in the storage box 505, the inner conveyor belt 507 is activated to transport them to the rear conveyor assembly 4. Then, the books in the front conveyor assembly 5 are transferred to the outer conveyor belt 401 in the rear conveyor assembly 4 and placed on the lower heat shrink film 207. The first lifting hydraulic cylinder 201 is controlled to press down the hot cutting frame 208, and the heating resistance wires in the hot cutting frame 208 are activated to heat-press and bond the upper heat shrink film 206 and lower heat shrink film 207 of the book together, completing the plastic wrapping of the book. In conjunction with the outer conveyor belt 401, the book is transferred to the conveyor roller 405. The hot air blowers 302 at the upper and lower ends are activated to blow air onto the outer wall of the plastic-wrapped book, thereby shrinking the heat shrink film and tightly wrapping the book. The stacking isolation seat 802 is then placed on the stacking isolation seat 802. Inserted along the positioning groove onto the roller 706, the height of the palletizing isolation seat 802 on the feeding tray 705 is adjusted by the lifting and feeding hydraulic cylinder 701, so that the palletizing isolation seat 802 on the feeding tray 705 is flush with the upper conveying roller 405. By starting and controlling the small transmission motor, the conveying gear is rotated, which in turn drives several conveying rollers 405 on the chain to convey the heat-shrink-wrapped books to the palletizing isolation seat 802 on the inward sliding transfer assembly 7. Then, the drive motor in the drive mechanism 702 is started to move the outward sliding transfer assembly 8 along the inner slide rail 703, and cooperates with the pick-and-place assembly 6 to move the palletizing isolation seat 802 and the books in the palletizing isolation seat 802 onto the outer sliding transfer assembly 8. The height of the palletizing isolation seat 802 and the electric suction cup 603 on the feeding tray 705 is adjusted by controlling the lifting and feeding hydraulic cylinder 701 and the third lifting hydraulic cylinder 601, so that the two are level and the palletizing isolation seat 802 on the feeding tray 705 is at the top of the palletizing seat or the uppermost palletizing isolation seat 802 on the palletizing seat. The electric suction cup 603 is moved by controlling the pulling hydraulic cylinder 602. When the electric suction cup 603 is attached to the outer wall of the palletizing isolation seat 802 on the feeding tray 705, the electric suction cup 603 is opened to perform suction. Then, the electric suction cup 603 is operated to pick up the palletizing isolation seat 802 on the feeding tray 705 and move it above the palletizing seat. Finally, the palletizing seat is pushed along the outer slide rail seat 801, and the stacked books can be pushed outward.

[0047] With the plastic wrapping component 2 in use, after the book in the current conveying component 5 is conveyed to the outer conveyor belt 401 in the rear conveying component 4 and is placed on the lower heat shrink film 207, the first lifting hydraulic cylinder 201 is controlled to press the hot cutting frame 208 downward and activate the heating resistance wire in the hot cutting frame 208 to heat-press and bond the upper heat shrink film 206 and the lower heat shrink film 207 of the book together, thus completing the plastic wrapping of the book. In conjunction with the outer conveyor belt 401, the book is conveyed to the conveyor roller 405 for thermoplastic tight wrapping.

[0048] In a further preferred embodiment of the present invention, the rear conveying component 4 includes a first bracket 402 and a second bracket 403 fixedly mounted on the main frame 1;

[0049] An outer conveyor belt 401 is provided on the inner wall of the first hanging frame 402;

[0050] The inner wall of the second bracket 403 is equipped with two side frame plates 404. The outer wall of the side frame plates 404 is fixedly connected to two small drive motors. The inner wall of each side frame plate 404 is embedded with two transmission gears. The outer wall of the transmission gears is meshed with a chain. The outer wall of the chain is fixedly connected to several transmission rollers 405. The output shaft of the small drive motor is fixedly connected to the outer wall of the transmission gear through a coupling.

[0051] In this embodiment, the rear conveyor assembly 4 enables the plastic wrapping, heat shrinking, and conveying of books: the books in the current conveyor assembly 5 are conveyed to the outer conveyor belt 401 in the rear conveyor assembly 4 and then plastic wrapped by the plastic wrapping assembly 2. After being conveyed by the outer conveyor belt 401 to several conveyor rollers 405, the heat-shrink wrapped books are directionally conveyed to the inward sliding transfer assembly 7 by starting and controlling the small transmission motor, which drives the conveyor gears to rotate, thereby driving the several conveyor rollers 405 on the chain.

[0052] In a further preferred embodiment of the present invention, the heat shrink assembly 3 includes a side frame 301 fixedly mounted on the main frame 1. A hot air blower 302 is provided at the bottom of the side frame 301. There are multiple hot air blowers 302, and the multiple hot air blowers 302 are respectively arranged between the bottom of the side frame 301 and the two side frame plates 404 in the rear conveying assembly 4.

[0053] In this embodiment, through the setting of the heat shrinking component 3 and its use in conjunction with the rear conveying component 4, the book in the current conveying component 5 is conveyed to the outer conveyor belt 401 in the rear conveying component 4 and then coated by the plastic coating component 2. After being conveyed by the outer conveyor belt 401 to several conveying rollers 405, the hot air blowers 302 at the upper and lower ends are started to blow air on the outer wall of the coated book, thereby shrinking the heat shrink film and tightly wrapping the book.

[0054] In a further preferred embodiment of the present invention, the front conveying assembly 5 includes an upper hanging plate 501 fixedly mounted on the main frame 1. A second lifting hydraulic cylinder 502 is fixedly connected to the bottom of the upper hanging plate 501. A connecting seat 503 is fixedly connected to one end of the second lifting hydraulic cylinder 502. A sliding bracket 504 is inserted into the inner wall of the connecting seat 503. Two storage frames 505 are fixedly connected to the bottom of the sliding bracket 504. An inner conveyor belt 507 is embedded in the lower inner wall of the storage frame 505. A pressing mechanism 506 is embedded in the upper inner wall of the storage frame 505.

[0055] Among them, the upper and lower ends of the two storage boxes 505 are fixedly connected to each other with a mating seat, and the mating seats on the two storage boxes 505 are mutually mating and slidingly connected. A first tensioning hydraulic cylinder 508 is connected between each set of mutually mating and slidingly connected mating seats.

[0056] The pressing mechanism 506 includes an inner sliding frame 5062 that is slidably connected to the inner wall of the storage frame 505, and a telescopic pressing hydraulic cylinder 5061 is connected between the inner sliding frame 5062 and the storage frame 505. Several pressing wheels 5063 are movably connected to the bottom inner wall of the inner sliding frame 5062, and the outer wall of the pressing wheel 5063 has corrugated grooves.

[0057] In this embodiment, through the setting of the front conveyor component 5, in use, firstly, according to the size of the books to be stacked, the first tensioning hydraulic cylinder 508 is used to pull and adjust the position between the two storage frames 505, and the bound books are placed into the two storage frames 505. The telescopic pressing hydraulic cylinder 5061 is controlled to press down the pressing roller 5063 to press the upper sides of the books, so that the four corners of the books are aligned and the warping of the book edges is reduced. The second lifting hydraulic cylinder 502 is controlled to lower the height of the storage frame 505 and continue to stack books into the storage frame 505. When several identical books or a set of books are stacked in the storage frame 505, the inner conveyor belt 507 is started to transport them to the rear conveyor component 4.

[0058] In a further preferred embodiment of the present invention, the inner sliding transfer assembly 7 includes an inner slide rail seat 703. The outer wall of the inner slide rail seat 703 is slidably connected to a drive mechanism 702. The top of the drive mechanism 702 is fixedly connected to a lifting and feeding hydraulic cylinder 701. The top of the lifting and feeding hydraulic cylinder 701 is fixedly connected to a rotary feeding motor 704. The output shaft of the rotary feeding motor 704 is fixedly connected to a feeding disc 705 through a coupling. The top of the feeding disc 705 is provided with a positioning groove. Several rollers 706 are movably connected to the inner wall of the positioning groove.

[0059] The drive mechanism 702 includes a T-shaped slide block that slides and engages with the inner slide rail seat 703. A drive motor and a pulley are provided on both sides of the T-shaped slide block, and the drive motor and the pulley are connected by a transmission rod.

[0060] The external sliding transfer assembly 8 includes an external slide rail seat 801 fixedly mounted on the main frame seat 1. A stacking seat is slidably connected to the outer wall of the external slide rail seat 801. Several stacking isolation seats 802 are sequentially inserted into the inner wall of the stacking seat, and several anti-slip textures 803 are provided on the top of the stacking isolation seats 802.

[0061] The pick-and-place assembly 6 includes a third lifting hydraulic cylinder 601 fixedly mounted on the main frame 1. An angle seat is fixedly connected to the top of the third lifting hydraulic cylinder 601. Two pulling hydraulic cylinders 602 are fixedly connected to the inner wall of the angle seat. An electric suction cup 603 is fixedly connected to the inner wall of the pulling hydraulic cylinder 602.

[0062] In this embodiment, through the setting of the inner sliding transfer component 7, during use, the palletizing isolation seat 802 is inserted into the roller 706 along the positioning groove. The rotary feeding motor 704 is started and controlled to select and adjust the direction of the palletizing isolation seat 802 for storing books. When the plastic-coated books are fed into the palletizing isolation seat 802 along the rear conveyor component 4, the drive motor in the drive mechanism 702 is started to move the outward sliding transfer component 8 along the inner slide rail seat 703, and cooperates with the pick-and-place component 6 to move the palletizing isolation seat 802 and the books in the palletizing isolation seat 802. Books are moved onto the outer sliding transfer assembly 8, reducing manual intervention and improving transfer and palletizing efficiency. When books are placed in the palletizing isolation seat 802, both gravity and frictional resistance increase. The arrangement of several rollers 706 and the palletizing isolation seat 802 reduces the frictional resistance between the feeding tray 705 and the palletizing isolation seat 802, thus facilitating the movement and placement of the palletizing isolation seat 802. The lifting feeding hydraulic cylinder 701 can adjust the height of the palletizing isolation seat 802 to facilitate the stacking and palletizing of the palletizing isolation seat 802 on the outer sliding transfer assembly 8.

[0063] In this embodiment, the outer sliding transfer component 8 is used in conjunction with the pick-and-place component 6 and the inner sliding transfer component 7. The height of the palletizing isolation seat 802 and the electric suction cup 603 on the feeding tray 705 are adjusted by controlling the lifting and feeding hydraulic cylinder 701 and the third lifting hydraulic cylinder 601, making them level. The palletizing isolation seat 802 on the feeding tray 705 is positioned at the top of the palletizing base or the uppermost palletizing isolation seat 802. The electric suction cup 603 is moved by controlling the pulling hydraulic cylinder 602. When the electric suction cup 603 is attached to the outer wall of the palletizing isolation seat 802 on the feeding tray 705, the electric suction cup is activated. The pallet 603 is used for adsorption, and then the electric suction cup 603 is operated to pick up the palletizing isolation seat 802 on the feeding tray 705 and move it above the palletizing seat for palletizing. The anti-slip texture 803 increases the frictional resistance between the inner wall of the palletizing isolation seat 802 and the heat shrink film covering the outer wall of the book, thereby achieving a better anti-slip effect. The palletizing isolation seat 802 can protect and isolate the outer wall of the book, preventing ink stains from sticking to the paper due to excessive pressure on the bottom book when the books are stacked directly in a high number of layers. Furthermore, stacking several palletizing isolation seats 802 also makes it convenient for users to disassemble and retrieve the books.
