Description

Technical Field

[0001] This invention relates to the field of book block transport equipment technology, and in particular to a quantitative dispensing mechanism for book block transport. Background Technology

[0002] The book block is a term in book publishing, referring to the book panels and endpapers bound together inside the book cover or before the cover is applied; it is also called a "raw book," meaning a bare book without a cover. It is the main body of the book, carrying its main content. In the bookmaking process, the book block is the part where folded book panels (or single pages) are arranged in order and bound together. However, after binding, the stacks of book blocks need to be transported to a designated location for trimming at the openings. One such pushing mechanism is as follows:

[0003] Chinese patent document CN217437246U discloses a paper feeding machine with a paper pushing structure. Specifically, it includes a paper feeding platform and a paper clamping robot arm located above the paper feeding platform. The paper feeding platform and the paper clamping robot arm are slidably mounted on a lifting beam and are driven by their respective power components. The lifting beam moves up and down in front of the frame. A paper feeding roller is provided at the left or right end of the paper feeding platform. A paper pushing mechanism is provided in the direction where the paper feeding roller is located. When the paper pushing mechanism is working, it quantitatively pushes the paper stack located between the paper feeding platform and the paper pushing mechanism onto the paper feeding platform.

[0004] As shown above, existing paper feeding machines, through their paper pushing mechanisms, have solved the problem of current paper feeding equipment being unable to quantitatively feed stacks of thick paper, cardboard, plastic boards, composite boards, etc. However, when the paper stack is placed between the paper feeding platform and the paper pushing mechanism, there is no limiting or positioning treatment for the paper stack. This may result in the paper stack not being aligned with the paper pushing mechanism, and the paper stack being prone to displacement during the pushing mechanism's movement, affecting subsequent processing. Therefore, a quantitative feeding mechanism for book block transportation is provided to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a quantitative feeding mechanism for book block transportation to address the shortcomings of existing technologies, thereby solving the technical problem that existing paper feeders do not perform limiting and positioning processing on the paper stack, which leads to easy deviation of the paper stack during movement.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A quantitative dispensing mechanism for transporting book blocks includes a frame and a strip support for supporting stacked book blocks. The strip support is fixedly mounted on the frame via a first mounting plate. It also includes a pair of limiting plates positioned above the strip support and used to limit the book blocks during stacking. The limiting plates are positioned opposite each other and on both sides of the stacking position on the strip support. On the other two sides of the stacking position, there are book-blocking modules that cooperate with the limiting plates to ensure that the book blocks are neatly stacked on the stacking position on the strip support.

[0008] The spacing between the limiting plates on both sides of the stacking position is adjustable, and the spacing between the book blocking modules on the other two sides of the stacking position is also adjustable.

[0009] Furthermore, a lifting mechanism is installed on the frame, and a primary pusher is provided on the lifting mechanism for pushing a fixed amount of book blocks to the next mechanism.

[0010] Furthermore, a second linear module is provided on the frame, with its length direction aligned with that of the strip support. A limiting plate located on one side of the stacking position is mounted on the second linear module, while a limiting plate located on the other side of the stacking position is fixedly mounted on the frame.

[0011] Furthermore, a second linear module is provided on the frame, with its length direction aligned with that of the strip support. A limiting plate located on one side of the stacking position is mounted on the second linear module, while a limiting plate located on the other side of the stacking position is fixedly mounted on the frame.

[0012] Furthermore, the book-blocking module includes a first limiting rod fixedly mounted on the support frame and a second limiting rod movably mounted on the support frame. The direction of movement of the second limiting rod is consistent with the length direction of the strip bracket, and the second limiting rod is close to the movable limiting plate. A driving component for driving the second limiting rod to move is provided on the support frame. A support plate is provided on the frame, and a power module for driving the driving component and the second linear module to run simultaneously is provided on the support plate.

[0013] Furthermore, the driving component includes a first lead screw mounted on the support frame and axially aligned with the length direction of the strip bracket; a first movable frame slidably mounted on the support frame and threadedly connected to the first lead screw; a second limiting rod mounted on the first movable frame; and a universal spline drive shaft at the end of the first lead screw that enables it to be connected to the power module for transmission.

[0014] Furthermore, the first linear module includes a first fixed frame mounted on a frame, a second lead screw arranged horizontally within the first fixed frame, and the axial direction of the second lead screw being perpendicular to the length direction of the strip support. The support frame is slidably mounted on the first fixed frame and threadedly connected to the second lead screw. A second servo motor is also mounted on the first fixed frame. A fifth gear is provided on the output shaft of the second servo motor and the end of the second lead screw. A toothed belt for transmission is wound around the fifth gear.

[0015] Furthermore, the first-level pusher includes a support seat fixedly mounted on the lifting mechanism. The support seat is located below the strip support. A slide rail is provided on the support seat, and the length direction of the slide rail is consistent with the length direction of the strip support. A slider is provided on the slide rail, and a fixed plate is provided on the slider, which is located below the strip support. A pair of pusher seats for pushing quantitative book blocks are provided on the fixed plate, and the pusher seats are respectively located on both sides of the strip support.

[0016] Furthermore, a rotating shaft with an axial direction perpendicular to the length direction of the strip bracket is provided at one end of the support base, and a first gear is provided on the rotating shaft. A fixed seat is provided at the end of the support base away from the rotating shaft, and a second gear is provided on the fixed seat. A first transmission belt is wound around the first gear and the second gear. The fixed plate is fixedly connected to one section of the first transmission belt through a connecting block. A drive unit for driving the rotating shaft to rotate is installed on the support base.

[0017] Furthermore, it also includes a pair of anti-friction modules respectively set on different pusher seats to separate the top of the pusher seat from the remaining book block; the anti-friction module includes an anti-friction strip, and connecting seats are installed at both ends of the support seat, and the two ends of the anti-friction strip are fixedly set to different connecting seats respectively. Inside the pusher seat, there are a first roller module and a second roller module arranged vertically. The anti-friction strip is wrapped around the first roller module and the second roller module so that the anti-friction strip is in the shape of "U". A section of the anti-friction strip wrapped around the first roller module is placed on the top of the pusher seat to contact the remaining book block.

[0018] The beneficial effects of this invention are as follows: When books are continuously stacked on the strip support, the book block is placed between the two limiting plates. The distance between the limiting plates is consistent with the width of the book block. The limiting plates limit the book block during the stacking process, making the stacked book blocks more neat. The book blocking module is used to limit the wide side of the book block, and the limiting plate is used to limit the long side of the book block. With the cooperation of the limiting plate and the book blocking module, the book blocks stacked on the strip support can be made more neat, improving the stacking effect of the book blocks and allowing the book blocks to be pushed to the next mechanism accurately.

[0019] In addition, the spacing between the limiting plates and the spacing between the book blocking modules are adjustable to limit the book blocks of different sizes, which improves the practicality of the mechanism. Attached Figure Description

Detailed Implementation

[0034] The following is a detailed description of a quantitative dispensing mechanism for book block transportation according to the present invention, with reference to the accompanying drawings.

[0035] like Figure 1-3 As shown, an embodiment of the quantitative dispensing mechanism for book block transportation according to the present invention includes a frame 1 and a strip support 302 for supporting stacked book blocks. The strip support 302 is fixedly mounted on the frame 1 by a first mounting plate 101. A book feeding mechanism (not shown in the figure) located beside the frame 1 continuously conveys the book blocks to the stacked position on the strip support 302, and the book blocks conveyed to the strip support 302 are stacked. A lifting mechanism 2 is also installed on the frame 1, and a primary pusher 3 is provided on the lifting mechanism 2 for pushing the quantitatively dispensed book blocks to the next mechanism. The primary pusher 3 pushes the book blocks stacked on the strip support 302, thereby pushing the quantitatively dispensed book blocks to the next mechanism, realizing automatic dispensing of the book blocks to facilitate subsequent cutting processing. The dispensing direction of the book blocks is consistent with the length direction of the strip support 302.

[0036] To ensure precise stacking of the book blocks on the strip support 302, this quantitative dispensing mechanism also includes a pair of limiting plates 401 positioned above the strip support 302 to limit the book blocks during stacking. The limiting plates 401 are positioned opposite each other on either side of the stacking position (the stacking position on the strip support 302), with the spacing between the limiting plates 401 matching the width of the book blocks. When the book blocks are stacked on the strip support 302, they are positioned between the two limiting plates 401, and the book blocks are dispensed using the limiting plates 401. The book blocks are positioned to ensure they are stacked neatly. Additionally, book-blocking modules 402 are provided on both sides of the stacking position (the stacking position on the strip support 302) to work in conjunction with the limiting plate 401. The book-blocking modules 402 limit the width of the book blocks, while the limiting plate 401 limits the length of the book blocks. The cooperation of the limiting plate 401 and the book-blocking modules 402 ensures that the book blocks stacked on the strip support 302 are more neatly arranged, improving the stacking effect.

[0037] Specifically, when book blocks are continuously fed onto the strip support 302 for stacking, once they are stacked above the first-level pusher 3, the first-level pusher 3 is activated to move a fixed quantity of book blocks to the next mechanism. The remaining book blocks are blocked by the limiting plate 401 placed next to the first-level pusher 3, so that the remaining book blocks are placed on top of the first-level pusher 3. When the first-level pusher 3 is activated and reset to its initial position, the book blocks placed on top of the first-level pusher 3 automatically fall onto the strip support 302. This allows the first-level pusher 3 to be activated again to push the book blocks whenever they are stacked above the first-level pusher 3, and the number of book blocks pushed out each time is the same, so as to continuously process a fixed quantity of book blocks and greatly improve the transportation efficiency of book blocks. Additionally, the frame is equipped with a support rod 409 for stably stacking the book blocks on the strip support 302. The strip support 302 supports the middle position of the bottom of the book block, and the support rod 409 supports the edge position of the bottom of the book block. The combined action of the strip support 302 and the support rod 409 provides stable support for the stacked book blocks.

[0038] like Figure 4-5 As shown, in order to neatly stack book blocks of different sizes, the spacing between the limiting plates 401 placed on both sides of the stacking position is adjustable, and the spacing between the book-blocking modules 402 placed on the other two sides of the stacking position is also adjustable. Specifically, a second linear module 408 is provided on the frame 1, with its length direction aligned with the length direction of the strip support 302. The limiting plate 401 placed on one side of the stacking position is mounted on the second linear module 408, while the limiting plate 401 placed on the other side of the stacking position is fixedly mounted on the frame 1. By operating the second linear module 408, the limiting plate 401 on one side is moved along the length direction of the strip support 302, thereby adjusting the spacing between the two limiting plates 401 to accommodate the width dimensions of different book blocks. In addition, a pair of opposing first linear modules 405 are provided on the frame 1, and each first linear module 405 is provided with a support frame 403. By operating the opposing first linear modules 405, the support frames 403 on both sides can move towards each other or away from each other. Secondly, the book blocking modules 402 placed on both sides of the stacked book position are respectively set on different support frames 403. When the support frames 403 move towards each other or away from each other, the distance between the book blocking modules 402 on both sides can be adjusted to adapt to the length of different book blocks.

[0039] Furthermore, the book-blocking module 402 includes a first limiting rod 4021 fixedly mounted on the support frame 403 and a second limiting rod 4022 movably mounted on the support frame 403. The direction of movement of the second limiting rod 4022 is consistent with the length direction of the strip bracket 302, so that the distance between the first limiting rod 4021 and the second limiting rod 4022 is adjustable. The second limiting rod 4022 is close to the movable limiting plate 401. A driving member 404 is provided on the support frame 403 to drive the second limiting rod 4022 to move. A support plate 406 is provided on the frame 1, and a power module 407 is provided on the support plate 406 to drive the driving member 404 and the second linear module 408 to operate simultaneously. By operating the power module 407, the drive unit 404 and the second linear module 408 are driven to operate simultaneously, driving the limiting plate 401 and the second limiting rod 4022 on one side to move simultaneously to the same side. This adjusts the distance between the first limiting rod 4021 and the second limiting rod 4022, and the distance between the limiting plates 401 placed on both sides of the stacked book position, to accommodate book blocks of different sizes, thus improving the practicality of the mechanism.

[0040] like Figure 6-7 As shown, the driving component 404 includes a first lead screw 4041 disposed on the support frame 403 and whose axial direction is consistent with the length direction of the strip bracket 302. A first movable frame 4042 is slidably disposed on the support frame 403 and is threadedly connected to the first lead screw 4041. A second limiting rod 4022 is mounted on the first movable frame 4042. A universal spline drive shaft 4043 is provided at the end of the first lead screw 4041 to drive the power module 407. By operating the power module 407 to transmit power to the universal spline drive shaft 4043, thereby driving the first lead screw 4041 to rotate, the first movable frame 4042 can move along the length direction of the strip bracket 302 on the support frame 403, adjusting the distance between the first limit rod 4021 and the second limit rod 4022; and when the position of the support frame 403 changes, the power module 407 can also drive the first lead screw 4041 to rotate under the action of the universal spline drive shaft 4043.

[0041] Furthermore, the first linear module 405 includes a first fixed frame 4051 mounted on the frame 1. A second lead screw 4052 is horizontally arranged inside the first fixed frame 4051, and the axial direction of the second lead screw 4052 is perpendicular to the length direction of the strip bracket 302. The support frame 403 is slidably mounted on the first fixed frame 4051 and threadedly connected to the second lead screw 4052. In order to enable the support frame 403 to slide automatically, a second servo motor 4053 is also mounted on the first fixed frame 4051. A fifth gear 4054 is provided on the output shaft of the second servo motor 4053 and the end of the second lead screw 4052. A toothed belt 4055 for transmission is wound around the fifth gear 4054. The second servo motor 4053 is started, and the second lead screw 4052 is driven to rotate through the fifth gear 4054 and the toothed belt 4055, so that the support frame 403 moves on the first fixed frame 4051 in the direction of approaching or moving away from the strip bracket 302, so as to adjust the distance between the two side book blocking modules 402.

[0042] The second linear module 408 includes a second fixed frame 4081 mounted on the frame 1. A third lead screw 4082, whose axial direction is aligned with the length direction of the strip-shaped support 302, is located within the second fixed frame 4081. One end of the third lead screw 4082 is connected to the power module 407 via a transmission connection. A second movable frame 4083 is slidably mounted on the second fixed frame 4081. A limiting plate 401, positioned on one side of the stacked book position, is fixedly mounted on the second movable frame 4083, and the second movable frame 4083 is threadedly connected to the third lead screw 4082. When the power module 407 is running, it simultaneously drives the first lead screw 4041 and the third lead screw 4082 to rotate, thereby simultaneously adjusting the distance between the limiting plates 401 on both sides of the stacked book position, and the distance between the first limiting rod 4021 and the second limiting rod 4022.

[0043] like Figure 8 As shown, the lifting mechanism 2 includes a pair of fixed blocks 201 mounted on the frame 1. A lifting frame 202 is movably mounted on the fixed blocks 201, and a primary pusher 3 is mounted on the lifting frame 202. A drive assembly 203 for driving the lifting frame 202 to move up and down is also provided on the fixed blocks 201. When it is necessary to adjust the number of book blocks output, the drive assembly 203 is activated to drive the lifting frame 202 to move up and down, thereby moving the primary pusher 3 up and down as well, thus adjusting the height of the primary pusher 3. Because the strip support 302 is fixed and the position of the book blocks remains unchanged, different numbers of book blocks can be output when the height of the primary pusher 3 changes, and it can also accommodate book blocks of different thicknesses.

[0044] like Figure 9-10As shown, the first-level pusher 3 includes a support base 301 fixedly mounted on the lifting frame 202. The support base 301 is located below the strip support 302. A slide rail 303 is provided on the support base 301, and the length direction of the slide rail 303 is consistent with the length direction of the strip support 302. A slider 304 is provided on the slide rail 303, and a fixing plate 305 is provided on the slider 304, which is located below the strip support 302. Under the action of the slide rail 303 and the slider 304, the fixing plate 305 can slide back and forth on the support base 301 along the length direction of the strip support 302. A pair of pusher seats 306 for pushing quantitative book blocks are provided on the fixing plate 305, and the pusher seats 306 are respectively located on both sides of the strip support 302. The side of the pusher seat 306 that contacts the book block is perpendicular to the horizontal plane. The book blocks are continuously conveyed to the stacking position on the strip support 302 for stacking. Once the stack is higher than the pusher seat 306, the fixed plate 305 is driven to move towards the book blocks. The pusher seat 306 pushes a fixed quantity of book blocks to the next mechanism, realizing automatic discharging of the book blocks. The remaining book blocks are blocked by the limiting plate 401 fixed on the frame 1, so that the remaining book blocks are placed on top of the pusher seat 306. When the fixed plate 305 is driven back to the initial position, the book blocks placed on top of the pusher seat 306 automatically fall onto the strip support 302. This allows the pusher seat 306 to push the book blocks whenever the stack is higher than the pusher seat 306, and the number of book blocks pushed out each time is the same. This achieves continuous pushing of a fixed quantity of book blocks, greatly improving the transportation efficiency of the book blocks.

[0045] To drive the fixed plate 305 to move on the support base 301, a rotating shaft 307 with its axis perpendicular to the length direction of the strip bracket 302 is provided at one end of the support base 301, and a first gear 308 is provided on the rotating shaft 307. In addition, a fixed base 309 is provided at the end of the support base 301 away from the rotating shaft 307, and a second gear 310 is provided on the fixed base 309. A first transmission belt 311 is wound around the first gear 308 and the second gear 310. The fixed plate 305 is fixedly connected to one section of the first transmission belt 311 (the first transmission belt 311 wound around the first gear 308 and the second gear 310 is divided into upper and lower sections) through a connecting block 312. After the rotating shaft 307 is driven to rotate, the first transmission belt 311 is driven to move under the action of the first gear 308, thereby driving the pusher seat 306 to move towards the book block through the fixed plate 305, thereby pushing the stacked book block. Furthermore, a second mounting plate 314 is provided on the support base 301, and a first servo motor 315 is mounted on the second mounting plate 314. The output shaft of the first servo motor 315 is provided with a fourth gear 316, and a third gear 313 is provided on the rotating shaft 307. A second transmission belt 317 is wound around the third gear 313 and the fourth gear 316. Specifically, when it is necessary to push the material, the first servo motor 315 is started, and the rotating shaft 307 is driven to rotate through the third gear 313, the fourth gear 316 and the second transmission belt 317. Then, the rotating shaft 307 is used for transmission to drive the pusher seat 306 to move towards the book block, thereby realizing the automatic pushing process of the book block and pushing a certain amount of book block to the next mechanism.

[0046] like Figure 11 As shown, when the pusher 306 pushes a fixed quantity of book blocks to the next mechanism, the remaining book blocks are blocked by the limiting plate 401 fixed on the frame 1, so that the remaining book blocks are placed on the top of the pusher 306. However, during the movement of the pusher 306, its top will rub against the book blocks, which will damage the book blocks. To solve the above problem, the first-stage pusher also includes a pair of anti-friction modules respectively set on different pushers 306. The anti-friction modules separate the top of the pusher 306 from the remaining book blocks. When the pusher 306 pushes the book blocks, the anti-friction modules slide on the pusher 306, so that the top of the pusher 306 will not rub against the remaining book blocks, thus avoiding damage to the book blocks.

[0047] The anti-friction module includes an anti-friction belt 320. Connecting seats 318 are installed at both ends of the support base 301, and the two ends of the anti-friction belt 320 are fixedly installed with different connecting seats 318 respectively. In addition, a first roller module and a second roller module are arranged vertically inside the pusher base 306. The anti-friction belt 320 is wrapped around the first roller module and the second roller module so that the anti-friction belt 320 is in a "U" shape. A section of the anti-friction belt 320 wrapped around the first roller module is placed on the top of the pusher base 306 to contact the remaining book block, and the anti-friction belt 320 is in a taut state. During the pushing process of the pusher seat 306, because the two ends of the anti-friction belt 320 are fixedly set, the anti-friction belt 320 slides on the top of the pusher seat 306. The anti-friction belt 320 on the top of the pusher seat 306 contacts the book block, but does not rub against the book block. This prevents friction between the pusher seat 306 and the book block during movement, thus avoiding damage to the book block and improving the transport efficiency of the book block. In addition, the first roller module includes a pair of first rollers 321 at the same height, and the second roller module includes a pair of second rollers 322 at the same height. The first rollers 321 and the second rollers 322 make the pusher seat 306 move more smoothly.

[0048] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0049] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
