Description

Technical Field

[0001] The present invention generally relates to the technical field of packaging, and in particular to a book reversing stacking machine. Background Art

[0002] Books are books or texts bound into volumes, and their production process mainly includes plate making, printing, binding, packaging and palletizing. In the process of packing books, in order to facilitate packaging and transportation, it is often necessary to stack multiple books and pack them together. However, when the book is laid flat, its surface is not flat, and the height of the binding side of the book will be slightly higher. This makes it difficult to pack and fix if multiple books with the same placement direction are stacked together. Therefore, in the process of stacking books, some books need to be rotated horizontally 180° so that the binding side of the book is reversed. In the stacking process, two books with different placement directions are stacked in sequence, and the binding sides of the books are evenly distributed on the left and right sides of the book stack, so that the surface of the book stack is flat. However, if the books are rotated and packed manually, not only is the operation monotonous, but the workload is large, resulting in low efficiency in the packaging and transportation of books.

[0003] In order to solve the above problems, the existing patent provides a multi-copy book turning stacking machine (application number: CN202311142969.8), which includes a turning frame, on which an upper rotating part and a lower rotating part for rotating books are provided; the upper rotating part includes a mounting plate fixed to the top of the turning frame, and a clamping cylinder is installed at the lower end of the mounting plate, and the lower end of the clamping cylinder is rotatably connected to an upper pressing bracket through a rotating cylinder, and the lower rotating part includes a book bracket, which is driven by a driving mechanism to be lifted and rotated; when the book is transported between the upper rotating part and the lower rotating part, the driving mechanism drives the book bracket to rise upward, and the clamping cylinder drives the upper pressing bracket to descend until the book is clamped between the book bracket and the upper pressing bracket, and then the driving mechanism drives the book bracket to rotate, and the rotating cylinder drives the upper pressing bracket to rotate, thereby automatically driving the book to rotate 180°.

[0004] However, the above scheme has the following problems: 1. The upper pressure bracket is rotated by a rotating cylinder, and the rotating cylinder is driven to rise and fall by a clamping cylinder, so that in addition to the driving mechanism of the lower rotating part, the upper rotating part also needs to be driven by two sets of cylinders, resulting in a more complicated operation process of the multi-book turning stacking machine and a higher cost; 2. When clamping books, the lower rotating part drives the book bracket to rise through the driving mechanism, and at the same time, the upper rotating part drives the upper pressure bracket to descend through the clamping cylinder until the book is clamped firmly. Since the clamping force of the cylinder is large and the paper of the book is thin, it is easy to leave dents on the surface of the book when clamping, and even cause damage to the book, which has poor practicality. Summary of the invention

[0005] In view of the above-mentioned defects or shortcomings in the prior art, it is desired to provide a book reversing stacking machine, in which the lower pressure plate is driven to rise, fall and rotate through a driving mechanism, and drives the upper pressure plate to rotate synchronously, so that there is no need to set a cylinder, motor or other driving parts on the upper pressure plate to actively drive the upper pressure plate to rise, fall or rotate, so that the reversing operation of the book is more convenient and the cost of manufacturing the book stacking machine is greatly reduced; and the upper pressure plate applies an elastic clamping force to the book through the reset elastic force of the first elastic part, ensuring that the book can be stably clamped between the upper pressure plate and the lower pressure plate while avoiding excessive clamping force to leave dents on the surface of the book or damage the book, and the practicality is good.

[0006] The effect of the present invention is achieved in this way: The present application provides a book reversing stacking machine, comprising a frame, two conveyor belts are arranged at intervals in front and behind the frame, the interval between the two conveyor belts forms a reversing zone, and the conveyor belt is configured to transmit books backward; an active rotating mechanism and a driven rotating mechanism are also arranged on the frame, the active rotating mechanism comprises a first driving mechanism and a lower pressing plate, the lower pressing plate is located in the reversing zone and the front and rear ends of the lower pressing plate are connected to the conveyor belts on the front and rear sides, the driving mechanism is configured to drive the lower pressing plate to rise and fall in the vertical direction and rotate in the horizontal direction; the driven rotating mechanism comprises a gantry located at the top of the frame, the gantry comprises a horizontal beam arranged at the top, a support member slidably connected to the horizontal beam in the vertical direction, and an upper pressing plate rotatably connected to the support member, the upper pressing plate can rotate in the horizontal direction relative to the support member, a first elastic member is arranged between the cross beam and the support member, the first elastic member applies elastic force to the support member, thereby making the upper pressing plate always have a tendency to move downward; the upper pressing plate and the lower pressing plate are located in the same vertical plane, and a certain interval is left between the upper pressing plate and the lower pressing plate, and the interval forms a clamping zone; The book reversing stacker includes switchable input state, rotation state and output state. In the input state, the surfaces of the conveyor belt and the lower pressure plate are flush, the height of the clamping area is high, and the conveyor belt transfers the book backward to the reversing area; when the book enters the lower pressure plate, the book reversing stacker enters the clamping state, the driving mechanism drives the lower pressure plate to move upward to exceed the upper surface of the conveyor belt, the height of the clamping area becomes narrower, the lower pressure plate drives the book to move upward and squeeze the upper pressure plate, the upper pressure plate and the support member move upward, the first elastic member produces elastic deformation, and applies a reset elastic force to the support member, so that the upper pressure plate applies an elastic clamping force to the book, and the book is clamped between the upper pressure plate and the lower pressure plate, and then the driving mechanism drives the lower pressure plate to rotate in the horizontal direction by a preset angle, and the upper pressure plate and the book are driven by the lower pressure plate to rotate synchronously; in the output state, the driving mechanism drives the lower pressure plate to descend and reset to be flush with the conveyor belt, and the conveyor belt transfers the book on the lower pressure plate backward.

[0007] Furthermore, a mounting hole extending in the vertical direction is provided on the support, and an upwardly extending rotating shaft is provided at the upper end of the upper pressing plate. The rotating shaft is rotatably connected to the support through the mounting hole, and the rotating shaft can rotate circumferentially in the mounting hole, and drive the upper pressing plate to rotate in the horizontal direction relative to the support; a limiting structure is also provided between the rotating shaft and the mounting hole, and the limiting structure includes a plurality of clamping members and limiting grooves, and the plurality of clamping members are circumferentially provided on one of the outer wall of the rotating shaft and the inner wall of the mounting hole, and the plurality of limiting grooves are correspondingly provided on the outer wall of the rotating shaft and the other of the inner wall of the mounting hole; when the upper pressing plate rotates by a preset angle, the clamping member is clamped into the limiting groove, so that the upper pressing plate cannot rotate further relative to the support. When the lower pressing plate rotates by a preset angle, the clamping member is clamped into the limiting groove, so that the upper pressing plate cannot rotate further relative to the support, thereby offsetting the influence of inertia, so that the book clamped between the two can maintain a flat posture, which is convenient for subsequent transmission and packaging operations.

[0008] Furthermore, a plurality of first slide grooves are provided radially hollowed out on the upper side of the support member, the clamping member is slidably connected to the support member through the first slide grooves, and a plurality of limit grooves are correspondingly provided on the outer wall of the rotating shaft. When the upper pressing plate is driven to rotate, the clamping member can slide into the first slide groove and avoid the limit groove, so that the rotation process of the support member can be more stable and smooth.

[0009] Furthermore, a second elastic member is provided in the first slide groove, and the second elastic member pushes the clamping member, so that the clamping member always has a tendency to be clamped into the limiting groove. The clamping member can automatically clamp into the limiting groove to achieve limiting under the elastic force of the second elastic member, thereby making the rotation limiting operation of the upper pressing plate easier.

[0010] Furthermore, the gantry also includes a support frame of a frame structure, the support member is connected to the support frame, and an upwardly extending connecting rod is arranged at the upper end of the support frame, and the connecting rod is slidably connected to the cross beam along the vertical direction, thereby driving the upper pressure plate to move up and down relative to the cross beam; the first elastic member is a spring, and the first elastic member is sleeved on the connecting rod. Not only is the connection strength good, but the first elastic member is sleeved on the connecting rod, which not only enables the support frame to drive the upper pressure plate to have a downward pressing tendency, but also makes the installation of the first elastic member more convenient.

[0011] Furthermore, the lower pressing plate and the upper pressing plate are connected by a linkage assembly, which includes a linkage member and a positioning member, the linkage member is arranged on one of the lower pressing plate and the upper pressing plate, the positioning member is arranged on the other of the lower pressing plate and the upper pressing plate, the linkage member is provided with a positioning groove extending in the vertical direction, the positioning member is connected to the linkage member through the positioning groove, so that the lower pressing plate and the upper pressing plate are relatively fixed in the horizontal direction. When the lower pressing plate rotates, the linkage member moves synchronously, and the groove wall of the positioning groove pushes the positioning member, so that the upper pressing plate rotates together with the lower pressing plate, making the transmission between the two more stable.

[0012] Furthermore, linkage members are arranged at the left and right ends of the lower pressing plate, positioning members are arranged at the left and right ends of the upper pressing plate, and the upper end of the positioning groove is opened. When installing and removing the upper pressing plate or the lower pressing plate is raised to clamp the book, the positioning members at both ends of the upper pressing plate can be inserted into or removed from the positioning groove from the opening of the positioning groove, making the installation and removal operation simple.

[0013] Furthermore, the bottom end of the upper pressing plate or the top end of the lower pressing plate is connected with two side blocks on the left and right sides, and the side blocks are configured to stop the left and right sides of the book. The side blocks can be slid and adjusted relative to the upper pressing plate or the lower pressing plate by the sliding adjustment assembly. By setting the side blocks to stop the left and right sides of the book, the book can maintain a correct posture after turning, which is convenient for subsequent stacking and packaging; and the spacing between the two side blocks can be adjusted to adapt to different books, which is more practical.

[0014] Furthermore, the sliding adjustment assembly includes a screw rod, the external threads on the left and right sides of the screw rod are arranged in opposite directions, the upper pressure plate is hollowed out along the length direction to provide a mounting groove, the screw rod is located in the mounting groove, the lower side of the mounting groove is provided with an opening, the upper ends of the two side blocks penetrate into the mounting groove and are respectively threadedly connected to the left and right sides of the screw rod, so that when the screw rod rotates circumferentially in the mounting groove, the two side blocks synchronously approach or move away from each other. The positioning member can not only cooperate with the linkage member to make the upper and lower pressure plates rotate synchronously, but also the positioning member can be used by the user to rotate and adjust the spacing between the two side blocks, and the adjustment operation is simple.

[0015] Furthermore, the driving mechanism includes a lifting driving mechanism and a rotating driving mechanism, the lower pressing plate is connected to the rotating driving mechanism and driven by the rotating driving mechanism to rotate in the horizontal direction, the lifting driving mechanism is located at the bottom of the rotating driving mechanism, and the lifting driving mechanism is configured to drive the rotating driving mechanism to rise or fall as a whole, thereby driving the lower pressing plate on the rotating driving mechanism to rise or fall, making the overall structure of the driving mechanism simpler and the driving operation easier.

[0016] Furthermore, the lifting drive mechanism includes a cam, a first transmission shaft and a first servo motor. The first transmission shaft is transversely arranged at the lower side of the rotation drive mechanism. The first servo motor is connected to one of the left and right ends of the first transmission shaft. The cam is fixedly connected to the first transmission shaft, so that when the first servo motor drives the first transmission shaft to rotate in the circumferential direction, the cam is driven by the first transmission shaft to perform a rotational motion. The top end of the cam abuts against the lower end of the rotation drive mechanism. In the rotating state, the cam rotates and pushes the rotation drive mechanism upward. In the output state, the cam rotates and drives the rotation drive mechanism to descend. The rotation of the cam drives the rotation drive mechanism to rise or fall, which is not only simple and stable in structure, but also has the advantages of high transmission efficiency and high precision in cam transmission.

[0017] Furthermore, the rotation drive mechanism includes a mounting frame, in which a second transmission shaft arranged in a vertical direction and a second servo motor connected to the bottom of the second transmission shaft are arranged, the lower pressure plate is connected to the top of the second transmission shaft, and the second servo motor is configured to drive the second transmission shaft to rotate around the circumference, thereby driving the upper lower pressure plate to rotate in the horizontal direction. By driving the lower pressure plate to rotate through the second servo motor, not only the adjustment operation is relatively simple, but also the adjustment accuracy is relatively high.

[0018] Furthermore, a plurality of long strip-shaped support plates are arranged at intervals along the length direction of the lower pressing plate, and the front and rear ends of each support plate are inserted between the gaps of two adjacent conveyor belts. This not only makes the width of the lower pressing plate larger and the supporting effect more stable, but also makes the book transmission process more stable.

[0019] Furthermore, the support plate can also be other structures, for example: a plurality of support plates are connected to the top of the lower pressure plate, and the support plate is a bent L-shaped plate, including a supporting portion and a stop portion that are inclined to each other and intersect with each other at the ends; along the front and rear directions, the front and rear ends of the lower pressure plate are hinged with support plates, the intersection of the supporting portion and the stop portion is hinged to the lower pressure plate, and the supporting portions of the two support plates are close to each other, and the stop portions of the two support plates are far away from each other; when the book reversing stacker is in the input state, the stop portions on both sides approach the horizontal and are respectively connected to the front and rear two The transmission belt on the side and the supporting parts on both sides are close to vertical, and the book is transmitted from the stopper on the front side to the supporting part; in the rotating state, the book is transmitted to the upper ends of the two supporting parts, and the supporting part rotates downward under the pressure of the book, and the stopper on both sides rotates upward synchronously to close to vertical, thereby stopping the front and rear ends of the book; in the output state, the conveyor belt on the rear side drives the book to move backward, and the book is transmitted from the supporting part to the stopper on the rear side, and the stopper rotates downward under the pressure of the book, and the supporting part rotates upward synchronously to close to vertical. Not only can the book slide into or out of the lower pressure plate along the stopper in the input state or output state, making the book transmission process stable; and in the rotating state, the stopper abuts against the front and rear ends of the book, so that the book is not easy to deflect under the influence of transmission inertia during the reversing process, so that the book can always remain flat, which is convenient for subsequent stacking and packaging.

[0020] Furthermore, a push rod is slidably connected to the lower pressing plate, and a second slide groove is provided in the middle of the lower pressing plate in the vertical direction, and the push rod slides up and down relative to the lower pressing plate through the second slide groove; the top end of the push rod abuts against the bottom ends of the two supporting parts, and the lower end of the push rod and the ends of the front and rear stop parts are hinged through a connecting rod assembly, so that when the push rod slides up and down, the connecting rod assemblies on both sides are driven to rotate up and down, thereby driving the stop parts on both sides to rotate upward or downward synchronously, making the rotation adjustment operation of the support plate more stable and simple.

[0021] Furthermore, the connecting rod assembly includes a first hinge and a second hinge, the outer ends of the stoppers on both the front and rear sides are hinged with the first hinge, the bottom ends of the first hinges on both the front and rear sides are hinged with the second hinge, and the other end of the second hinge is hinged to the bottom end of the push rod. The first hinge, the second hinge, the push rod and the support plate are hinged to each other to form a structure similar to a hinged four-bar linkage, so that the transmission process between the push rod and the support plate is more stable and smooth.

[0022] Furthermore, the push rod includes a limiting protrusion protruding outward from the circumference, and when the push rod slides downward, the limiting protrusion abuts against the top of the lower pressing plate, thereby preventing the push rod from sliding downward and disengaging from the second sliding groove, making the sliding process of the push rod more stable.

[0023] Furthermore, a third elastic member is provided between the push rod and the lower pressing plate. When the push rod slides downward, the third elastic member generates elastic deformation and applies a restoring elastic force to the push rod, so that the push rod has a tendency to slide upward. In the output state, when the books are transferred out of the stopper, the push rod can be kept at a higher position by the elastic force of the third elastic member, and the support plates on both sides can be kept in the initial state, so that the next batch of books can be transferred to the lower pressing plate.

[0024] The book reversing stacking machine provided by the present application has a lower pressure plate driven by a driving mechanism to lift and rotate, and an upper pressure plate is rotatably connected to a supporting member. In the rotating state, the lower pressure plate rises and clamps the book together with the upper pressure plate, and the upper pressure plate is driven by the lower pressure plate to rotate synchronously, so that there is no need to set a cylinder, a motor or other driving member on the upper pressure plate to actively drive the upper pressure plate to lift or rotate. It is only necessary to set a driving mechanism on the lower pressure plate to actively lift and rotate to complete the reversing operation of the book, making the reversing operation of the book more convenient and greatly reducing the cost of manufacturing the book stacking machine; not only that, by setting a first elastic member, when the upper and lower pressure plates clamp the book, the first elastic member applies a reset elastic force to the upper pressure plate and causes the upper pressure plate to apply an elastic clamping force to the book, ensuring that the book can be stably clamped between the upper and lower pressure plates, while the clamping force on the book will not be too large, thereby avoiding leaving dents on the surface of the book or damaging the book, and having good practicality.

DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0028] Please refer to the attached Figure 1-18The embodiment of the present application provides a book reversing stacking machine, including a frame 1, on which two conveyor belts 110 are arranged at intervals in front and behind, and the interval between the two conveyor belts 110 forms a reversing area 101, and the conveyor belt 110 is configured to transport books backward; the frame 1 is also provided with an active rotating mechanism and a driven rotating mechanism, the active rotating mechanism includes a first driving mechanism and a lower pressing plate 210, the lower pressing plate 210 is located in the reversing area 101, and the front and rear ends of the lower pressing plate 210 are connected to the conveyor belts 110 on the front and rear sides, and the driving mechanism is configured to drive the lower pressing plate 210 to rise and fall in the vertical direction and rotate in the horizontal direction; the driven rotating mechanism includes a The gantry 3 includes a horizontal beam 330 at the top, a support member 320 slidably connected to the beam 330 in the vertical direction, and an upper pressing plate 310 rotatably connected to the support member 320. The upper pressing plate 310 can rotate relative to the support member 320 in the horizontal direction. A first elastic member 340 is provided between the beam 330 and the support member 320. The first elastic member 340 applies elastic force to the support member 320, so that the upper pressing plate 310 always has a tendency to move downward; the upper pressing plate 310 and the lower pressing plate 210 are located in the same vertical plane, and a certain interval is left between the upper pressing plate 301 and the lower pressing plate 210, and the interval forms a clamping area 102; The book reversing stacking machine includes a switchable input state, a rotation state and an output state. In the input state, the surfaces of the conveyor belt 110 and the lower pressing plate 210 are flush, the height of the clamping area 102 is relatively high, and the conveyor belt 110 transfers the book backwards into the reversing area 101; when the book enters the lower pressing plate 210, the book reversing stacking machine enters a clamping state, and the driving mechanism drives the lower pressing plate 210 to move upward to exceed the upper surface of the conveyor belt, the height of the clamping area 102 becomes narrower, and the lower pressing plate 210 drives the book to move upward and squeeze the upper pressing plate 310, and the upper pressing plate 310 and the support member 320 moves upward, the first elastic member 340 produces elastic deformation and applies a restoring elastic force to the support member 320, so that the upper pressing plate 310 applies an elastic clamping force to the book, and the book is clamped between the upper pressing plate 310 and the lower pressing plate 210. Then the driving mechanism drives the lower pressing plate 210 to rotate 180° in the horizontal direction, and the upper pressing plate 310 and the book are driven by the lower pressing plate 210 to rotate synchronously; in the output state, the driving mechanism drives the lower pressing plate 210 to descend and reset to be flush with the conveyor belt 110, and the conveyor belt 110 transfers the book on the lower pressing plate 210 backwards.

[0029] In this embodiment, the lower pressing plate 210 is driven to lift and rotate by a driving mechanism, and the upper pressing plate 310 is rotatably connected to the support member 320. In the rotating state, the lower pressing plate 210 is lifted and clamps the book together with the upper pressing plate 310, and the upper pressing plate 310 is driven by the lower pressing plate 210 to rotate synchronously, so that there is no need to set a cylinder, motor or other driving member on the upper pressing plate 310 to actively drive the upper pressing plate 310 to lift or rotate. Only a driving mechanism is set on the lower pressing plate 210 to actively lift and rotate to complete the reversing operation of the book, so that the reversing operation of the book The operation is relatively convenient and the cost of manufacturing the book stacking machine is greatly reduced; moreover, by providing the first elastic member 340, when the upper pressing plate 310 and the lower pressing plate 210 clamp the book, the first elastic member 340 applies a restoring elastic force to the upper pressing plate 310 and enables the upper pressing plate 310 to apply an elastic clamping force to the book, thereby ensuring that the book can be stably clamped between the upper pressing plate 310 and the lower pressing plate 210 while the clamping force applied to the book is not too large, thereby avoiding leaving dents on the surface of the book or damaging the book, and having good practicality.

[0030] Please refer to the attached Figure 6-9 The cam 310 is provided with a plurality of locking members 322, 323 and 324 which are provided on a plurality of support members 320. The cam 310 is provided with a plurality of locking members 322 which are provided on a plurality of support members 320. The locking members 322 are provided with a plurality of locking members 322 which are provided on a plurality of support members 320.

[0031] The book is then tucked away from the bookcase 310 and the holder 300 is moved in an unsteady manner so that the bookcase 310 can be easily packed up and out of the way.

[0032] Among them, preferably, two groups of front-to-back symmetrical clamping parts 322 and limiting grooves 312 are arranged between the rotating shaft 311 and the mounting hole 321, so that every time the upper pressure plate 310 rotates 180°, the clamping parts 322 can be inserted into the limiting grooves 312, so that the upper pressure plate 310 and the lower pressure plate 210 can stably drive the book to rotate 180° each time they rotate, which just makes the binding side of the book change direction, which is convenient for packaging.

[0033] The widths of the lower pressing plate 210 and the upper pressing plate 310 are relatively large, so that the lower pressing plate 210 and the upper pressing plate 310 can clamp multiple books at one time and turn together, thereby further improving the packing and transportation efficiency of the books.

[0034] Please refer to the attached Figure 6-9 In some embodiments of the present application, a plurality of first slide grooves 323 are radially hollowed out on the support member 320, the clamping member 322 is slidably connected to the support member 320 through the first slide grooves 323, and a plurality of limiting grooves 312 are correspondingly arranged on the outer wall of the rotating shaft 311.

[0035] In this embodiment, by opening the first sliding groove 323 on the support member 320, when the upper pressure plate 310 is driven to rotate, the clamping member 322 can slide into the first sliding groove 323 and avoid the limiting groove 312, so that the rotation process of the support member 320 can be more stable and smooth.

[0036] Please refer to the attached Figure 6The rotating shaft 311 includes a columnar shaft body 311a and an annular collar 311b. The collar 311b and the shaft body 311a are fixed by a key connection, so that the collar 311b can be driven by the shaft body 311a to rotate and the installation and disassembly between the two are relatively convenient. The limiting groove 312 is provided on the outer wall of the collar 311b, and the processing operation is relatively convenient. Two ball bearings 325 spaced apart from each other are also embedded in the mounting hole 321. The shaft body 311a passes through the inner rings of the two ball bearings 325, and the collar 311b is clamped between the upper and lower ball bearings 325, which not only improves the connection strength between the rotating shaft 311 and the support member 320, but also makes the rotation process between the two smoother. The top end of the rotating shaft 311 passes through the upper ball bearing 325, and the upper end of the rotating shaft 311 is also screwed with a cover body 326. The diameter of the cover body 326 is larger than the inner ring of the ball bearing, so that the rotating shaft 311 remains relatively fixed in the vertical direction relative to the support member 320, and has good stability.

[0037] Of course, in other embodiments of the present application, the clamping member 322 may also be disposed on the outer wall of the rotating shaft 311 , and the inner wall of the mounting hole 321 is correspondingly recessed to form the limiting groove 312 .

[0038] Please refer to the attached Figure 6-7 In some embodiments of the present application, a second elastic member 324 is further provided in the first sliding groove 323 , and the second elastic member 324 pushes the clamping member 322 , so that the clamping member 322 always has a tendency to be clamped into the limiting groove 312 .

[0039] In this embodiment, by setting the second elastic member 324, whenever the upper pressure plate 310 rotates a preset angle, the clamping member 322 can automatically snap into the limiting groove 312 under the elastic force of the second elastic member 324 to achieve limiting, thereby making the rotation limiting operation of the upper pressure plate 310 easier.

[0040] Preferably, the second elastic member 324 is a spring, so that the second elastic member 324 has good elastic deformation ability and strength. The clamping member 322 is a steel ball, and the limiting groove 312 is a corresponding semicircular groove, so that when the upper pressing plate 310 rotates again, the clamping member 322 can be automatically extruded along the curved surface of the limiting groove 312, so that the rotation adjustment operation of the upper pressing plate 310 is smoother.

[0041] Please refer to the attached Figure 6-9 In some embodiments of the present application, the gantry 3 also includes a support frame 350 of a frame structure, the support member 320 is connected to the support frame 350, and an upwardly extending connecting rod 351 is provided at the upper end of the support frame 350. The connecting rod 351 is slidably connected to the beam 330 along the vertical direction, thereby driving the upper pressure plate 310 to move up and down relative to the beam 330; the first elastic member 340 is a spring, and the first elastic member 340 is sleeved on the connecting rod 351.

[0042] In this embodiment, the support frame 350 is slidably connected to the cross beam through the connecting rod 351, which not only has good connection strength, but also the first elastic member 340 is sleeved on the connecting rod 351, which not only enables the support frame 350 to drive the upper pressure plate 310 to have a downward pressing tendency, but also makes the installation of the first elastic member 340 more convenient.

[0043] Among them, the support frame 350 is a square frame structure composed of four rods, so that the overall structure of the support frame 350 is relatively simple. The front and rear ends of the support member 320 are screwed to the rods on the front and rear sides of the support frame 350, and connecting rods 351 are provided on the rods on the left and right sides of the support frame 350, so that the sliding adjustment process between the support frame 350 and the cross beam 330 is smoother.

[0044] Among them, the top ends of the two connecting rods 351 pass through and extend upward beyond the crossbeam 330, and a horizontal constraint plate 352 is also provided between the top ends of the two connecting rods 250. When the connecting rod 351 slides downward to the maximum distance, the constraint plate 352 abuts against the top end of the crossbeam 330, so that the connecting rod 351 cannot be separated from the crossbeam 330. Not only does it improve the connection strength between the connecting rod 351 and the crossbeam 330. In addition, by placing blocks of different heights between the constraint plate 352 and the crossbeam 330, the height of the constraint plate 352 can be adjusted, and then the height of the upper pressing plate 310 at the bottom of the connecting rod 351 can be adjusted, so that the upper pressing plate 310 can adjust the initial height according to the height of the book to be clamped, which is more practical.

[0045] Please refer to the attached Figure 4 In some embodiments of the present application, the lower pressing plate 210 and the upper pressing plate 310 are connected by a linkage assembly, and the linkage assembly includes a linkage member 220 and a positioning member 313. The linkage member 220 is arranged on one of the lower pressing plate 210 and the upper pressing plate 310, and the positioning member 313 is arranged on the other of the lower pressing plate 210 and the upper pressing plate 310. The linkage member 220 is provided with a positioning groove 221 extending in the vertical direction, and the positioning member 313 is connected to the linkage member 220 through the positioning groove 221, so that the lower pressing plate 210 and the upper pressing plate 310 remain relatively fixed in the horizontal direction. When the lower pressing plate 210 rotates, the linkage member 220 moves synchronously, and the groove wall of the positioning groove 221 pushes the positioning member 313, so that the upper pressing plate 310 rotates together with the lower pressing plate 210, so that the transmission between the two is more stable.

[0046] Please refer to the attached Figure 4 In some embodiments of the present application, the linkage member 220 is disposed at the left and right ends of the lower pressure plate 210, the positioning member 313 is disposed at the left and right ends of the upper pressure plate 310, and the upper end of the positioning groove 221 is opened.

[0047] In this embodiment, by setting the upper opening of the positioning groove 221, when installing and disassembling the upper pressure plate 310 or raising the lower pressure plate 210 to clamp the book, the positioning pieces 313 at both ends of the upper pressure plate 310 can be inserted into or detached from the positioning groove 221 from the opening of the positioning groove 221, making the installation and disassembly operations simple.

[0048] Of course, in other embodiments of the present application, the linkage member 220 can be arranged at the left and right ends of the upper pressing plate 310, the positioning member 313 can be arranged at the left and right ends of the lower pressing plate 210, and the lower end of the positioning groove 221 can be opened.

[0049] Please refer to the attached Figure 16-18 In some embodiments of the present application, two left and right side blocks 314 are connected to the bottom end of the upper pressing plate 310 or the top end of the lower pressing plate 210. The side blocks 314 are configured to stop the left and right sides of the book. The side blocks 314 can be slidably adjusted left and right relative to the upper pressing plate 310 or the lower pressing plate 210 through a sliding adjustment component.

[0050] In this embodiment, during the turning process of the book, under the influence of rotational inertia, the book may still deflect after the lower pressing plate 210 stops rotating, which affects the subsequent stacking and packaging operations. Therefore, by setting two left and right side blocks 314 to stop the left and right sides of the book, the book is constrained by the side blocks 314 during the turning process and is not easy to deflect, so that the book can maintain a correct posture after turning, which is convenient for subsequent stacking and packaging. In addition, the side blocks 314 can be adjusted to slide left and right relative to the upper pressing plate 310 or the lower pressing plate 210, so that when the book reversing stacking machine is used for books of different widths, it can adapt to different books by adjusting the distance between the two side blocks 314, which is more practical.

[0051] Please refer to the attached Figure 16-18 In some embodiments of the present application, the sliding adjustment component includes a screw rod 315, the external threads on the left and right sides of the screw rod 315 are set in opposite directions, the upper pressure plate 310 is hollowed out along the length direction to provide a mounting groove 316, the screw rod 315 is located in the mounting groove 316, the lower side of the mounting groove 316 is opened, the upper ends of the two side blocks 314 are inserted into the mounting groove 316 and are respectively threadedly connected to the left and right sides of the screw rod 315, so that when the screw rod 315 rotates circumferentially in the mounting groove 316, the two side blocks 314 synchronously approach or move away from each other.

[0052] In this embodiment, the two side blocks 314 are driven to move by a screw transmission, so that the sliding adjustment of the two side blocks 314 is relatively simple and stable; and the screw rod 315 is set on the upper pressure plate 310, and the positioning members 313 on the left and right sides of the upper pressure plate 310 are fixedly connected to the left and right ends of the screw rod 315, so that the positioning members 313 can not only cooperate with the linkage member 220 to make the upper pressure plate 310 and the lower pressure plate 210 rotate synchronously, but also the positioning members 313 can be used by the user to rotate and adjust the screw rod 315, thereby adjusting the distance between the two side blocks 314.

[0053] Please refer to the attached Figure 5 In some embodiments of the present application, the driving mechanism includes a lifting driving mechanism and a rotating driving mechanism. The lower pressure plate 210 is connected to the rotating driving mechanism and is driven by the rotating driving mechanism to rotate in a horizontal direction. The lifting driving mechanism is located at the bottom of the rotating driving mechanism. The lifting driving mechanism is configured to drive the rotating driving mechanism as a whole to rise or fall, thereby driving the lower pressure plate 210 on the rotating driving mechanism to rise or fall.

[0054] In this embodiment, by setting the driving mechanism as two separate lifting driving mechanisms and a rotating driving mechanism, the lower pressure plate 210 is driven to rotate by the rotating driving mechanism, and the lifting driving mechanism drives the rotating driving mechanism and the lower pressure plate 210 to lift and lower as a whole, so that the overall structure of the driving mechanism is simpler and the driving operation is easier.

[0055] Please refer to the attached Figure 2-3 In some embodiments of the present application, the lifting drive mechanism includes a cam 230, a first transmission shaft 231 and a first servo motor 232. The first transmission shaft 231 is laterally arranged at the lower side of the rotation drive mechanism. The first servo motor 232 is connected to one of the left and right ends of the first transmission shaft 231. The cam 230 is fixedly connected to the first transmission shaft 231, so that when the first servo motor 232 drives the first transmission shaft 231 to rotate in the circumferential direction, the cam 230 is driven by the first transmission shaft 231 to perform a rotational motion; the top end of the cam 230 abuts against the lower end of the rotation drive mechanism. In the rotating state, the cam 230 rotates and pushes the rotation drive mechanism upward; in the output state, the cam 230 rotates and drives the rotation drive mechanism to descend.

[0056] In this embodiment, when the book reversing stacker is in the input state, the lower surface of the cam 230 abuts against the bottom end of the rotating drive mechanism, so that the rotating drive mechanism can be in a lower position and the lower pressure plate 210 can be flush with the conveyor belt 110; when entering the rotating state, the first servo motor 232 drives the first transmission shaft 231 to rotate, the cam 230 rotates and causes the upper surface of the cam 230 to rotate upward, thereby pushing the rotating drive mechanism and driving the lower pressure plate 210 to rise; in the output state, the cam 230 rotates again and causes the lower surface of the cam 230 to rotate upward, so that the rotating drive mechanism sinks along the curved surface of the cam 230, and the lower pressure plate 210 is reset. Therefore, the rotating drive mechanism is driven to rise or fall by the rotation of the cam 230, which is not only simple and stable in structure, but also has the advantages of high transmission efficiency and high precision in cam transmission.

[0057] Of course, in other embodiments of the present application, the lifting drive mechanism can also drive the rotating drive mechanism to lift and lower through structures such as a cylinder and an electric push rod.

[0058] Please refer to the attached Figure 2-5 In some embodiments of the present application, the rotation drive mechanism includes a mounting frame 240, in which a second transmission shaft 241 arranged in a vertical direction and a second servo motor 242 connected to the bottom of the second transmission shaft 241 are arranged, and the lower pressing plate 210 is connected to the top of the second transmission shaft 241, and the second servo motor 242 is configured to drive the second transmission shaft 241 to rotate around the circumference, thereby driving the upper lower pressing plate 210 to rotate in the horizontal direction. By driving the lower pressing plate 210 to rotate by the second servo motor 242, not only the adjustment operation is relatively simple, but also the adjustment accuracy is relatively high.

[0059] Among them, preferably, the mounting frame 240 is a square frame structure with a relatively simple structure. The left and right ends of the bottom end of the mounting frame 240 are rotatably connected with roller bearings 243, and the left and right cams 230 are correspondingly fixedly connected to the first transmission shaft 231. The two roller bearings 243 are respectively abutted against the upper ends of the two cams 230. When the cam 230 is driven to rotate, the roller bearings 243 rotate along the curved surface of the cam 230 and drive the mounting frame 240 to rise or sink as a whole, so that the transmission process between the cam 230 and the mounting frame 240 is smoother and the transmission efficiency is higher.

[0060] Please refer to the attached Figure 1-3 In some embodiments of the present application, a plurality of long support plates 250 are arranged at the top of the lower pressure plate 210, and the plurality of support plates 250 are arranged at intervals along the length direction of the lower pressure plate 210, and the front and rear ends of each support plate 250 are inserted between the gaps between two adjacent conveyor belts 110.

[0061] In this embodiment, in order to increase the load and reduce the wear of the conveyor belt 110, a plurality of conveyor belts 110 are arranged at intervals along the left and right sides of the upper edge of the frame 1. By arranging a support plate 250 inserted between the gaps between the two conveyor belts 110 on the lower pressing plate 210, not only the width of the lower pressing plate 210 is made larger, but also the supporting effect is more stable; and in the input state, the books transmitted to the end of the conveyor belt 110 can be transmitted to the lower pressing plate 210 along the lower pressing plate 210; in the output state, the books on the lower pressing plate 210 can also be transmitted to the head end of the conveyor belt 110 at the rear side along the lower pressing plate 210, thereby making the book transmission process more stable.

[0062] Please refer to the attached Figure 13-15 In some embodiments of the present application, the support plate 250 can also be other structures, for example: a plurality of support plates 250 are connected to the top of the lower pressing plate 210, and the support plate 250 is a bent L-shaped plate, including a supporting portion 251 and a stop portion 252 that are inclined to each other and intersect with each other at the ends; along the front and rear directions, the front and rear ends of the lower pressing plate 210 are hinged with support plates 250, and the intersection of the supporting portion 251 and the stop portion 252 is hinged to the lower pressing plate 210, and the supporting portions 251 of the two support plates 250 are close to each other, and the stop portions 252 of the two support plates 250 are away from each other; when the book reversing stacker is in the input state, the stop portions 252 on both sides approach the water The book is flat and connected to the transmission belts 110 on the front and rear sides respectively, the supporting parts 251 on both sides are close to vertical, and the book is transferred from the front stopper 252 to the supporting part 251; in the rotating state, the book is transferred to the upper ends of the two supporting parts 251, and the supporting part 251 rotates downward due to the pressure of the book, and the stopper 252 on both sides rotates upward synchronously to close to vertical, thereby stopping the front and rear ends of the book; in the output state, the conveyor belt 110 on the rear side drives the book to move backward, and the book is transferred from the supporting part 251 to the stopper 252 on the rear side, and the stopper 252 rotates downward due to the pressure of the book, and the supporting part 251 rotates upward synchronously to close to vertical.

[0063] In this embodiment, by setting the support plate 250 as an L-shaped rod, not only can the book slide into or out of the lower pressing plate 210 along the stopper 252 in the input state or the output state, so that the book transmission process is stable; and in the rotating state, the stopper 252 abuts against the front and rear ends of the book, so that the book is not easy to deflect under the influence of transmission inertia during the reversing process, so that the book can always remain flat, which is convenient for subsequent stacking and packaging. In addition, only according to the movement of the book, the stopper 252 or the supporting part 251 can be pressed down to adjust the automatic rotation switching state of the support plate 250, without the need for electric drive, and the adjustment operation is relatively simple.

[0064] Among them, the top of the lower pressure plate 210 is recessed and provided with a first avoidance groove 212 extending in the front-to-back direction. When the supporting part 251 is pressed and rotated downward, the supporting part 251 turns into the first avoidance groove 212, and the top of the supporting part 251 is flush with the top of the lower pressure plate 210, so that the book can be placed on the lower pressure plate 210 more stably.

[0065] Please refer to the attached Figure 13-15 In some embodiments of the present application, a push rod 260 is slidably connected to the lower pressure plate 210, and a second slide groove 211 is provided in the middle part of the lower pressure plate 210 along the vertical direction. The push rod 260 slides up and down relative to the lower pressure plate 210 through the second slide groove 211; the top end of the push rod 260 abuts against the bottom ends of the two supporting parts 251, and the lower end of the push rod 260 and the ends of the front and rear stop parts 252 are hinged through a connecting rod assembly, so that when the push rod 260 slides up and down, the connecting rod assemblies on both sides are driven to rotate up and down, thereby driving the stop parts 252 on both sides to rotate upward or downward synchronously.

[0066] In this embodiment, the push rod 260 is slidably connected to the lower pressing plate 210, and the push rod 260 and the stoppers 252 on both sides are hinged through a connecting rod assembly, so that a connecting rod sliding groove structure is formed between the support plate 250, the push rod 260 and the connecting rod assembly, and the support plates 250 on both sides can rotate synchronously by sliding up and down the push rod 260. In the rotating state, when the book slides from the stopper 252 of the front support plate 250 to the supporting part 251, the front supporting part 251 presses down the push rod 260, and the push rod 260 drives the connecting rod assemblies on both sides to rotate synchronously, and further drives the stoppers 252 on both sides to rotate upward synchronously to stop the front and rear sides of the book. In the output state, when the book slides from the supporting part 251 of the rear supporting plate 250 to the stopper part 252, the rear stopper part 252 presses down the rear connecting rod assembly, and drives the push rod 260 to rise through the rear connecting rod assembly, and the push rod 260 pushes the supporting parts 251 on both sides upward to rotate upward, so that the supporting plates 250 on both sides can be reset synchronously. Therefore, the rotation adjustment operation of the supporting plate 250 is more convenient.

[0067] Please refer to the attached Figure 13-15 In some embodiments of the present application, the connecting rod assembly includes a first hinge 261 and a second hinge 262, the outer ends of the stop portions 252 on the front and rear sides are hinged to the first hinge 261, the bottom ends of the first hinges 261 on the front and rear sides are hinged to the second hinge 262, and the other end of the second hinge 262 is hinged to the bottom end of the push rod 260.

[0068] In this embodiment, the first hinge 261, the second hinge 262, the push rod 260 and the support plate 250 are hinged to each other to form a structure similar to a hinged four-bar linkage, so that the transmission process between the push rod 260 and the support plate 250 is more stable and smooth.

[0069] Please refer to the attached Figure 13-15 In some embodiments of the present application, the push rod 260 includes a limiting protrusion 263 protruding outward from the circumference. When the push rod 260 slides downward, the limiting protrusion 263 abuts against the top of the lower pressing plate 210, thereby preventing the push rod 260 from sliding downward and disengaging from the second sliding groove 211. This makes the sliding process of the push rod 260 more stable.

[0070] Among them, the top of the first avoidance groove 212 is recessed downward to form a second avoidance groove 213. When the supporting part 251 rotates into the first avoidance groove 212, the push rod 260 is pressed down by the supporting part 251, and the limiting protrusion 263 at the top of the push rod 260 is inserted into the second avoidance groove 213, so that the upper supporting part 251 can rotate to be flush with the top of the lower pressure plate 210, and the book can be stably placed on the lower pressure plate 210.

[0071] Please refer to the attached Fig.15 In some embodiments of the present application, a third elastic member 264 is provided between the push rod 260 and the lower pressure plate 210. When the push rod 260 slides downward, the third elastic member 264 generates elastic deformation and applies a restoring elastic force to the push rod 260, so that the push rod 260 has a tendency to slide upward.

[0072] In this embodiment, by providing the third elastic member 264, in the output state, when the book is transferred out of the stopper 252, the push member 260 can rotate upward against the supporting portions 251 on both sides under the elastic force of the third elastic member 264, and the push member 260 can be maintained at a relatively high position, and drive the support plates 250 on both sides to be maintained in the initial state, so as to facilitate the next batch of books to be transferred into the lower pressure plate 210.

[0073] Among them, preferably, the third elastic member 264 is a spring, the third elastic member 264 is sleeved on the pushing member 260, and the upper end of the third elastic member 264 abuts against the limiting protrusion 263, and the lower end of the third elastic member 264 abuts against the bottom of the second avoidance groove 213, so that the third elastic member 264 is easy to install.

[0074] Of course, in other embodiments of the present application, the third elastic member 264 may also be a torsion spring disposed at the hinged portion of the connecting rod assembly and the push rod 260, or a tension spring between the bottom of the lower pressure plate 210 and the connecting rod assembly, and so on.
