Description

Technical Field

[0001] The present invention relates to the technical field of paper stacking, and in particular to a paper stacking platform of a paper bundling machine. Background Art

[0002] After the paper is cut through multiple processes, it needs to be stacked to make books for subsequent printing.

[0003] Before bundling, the papers need to be stacked. Most stacking systems on the market rely on manual labor combined with a semi-automated mechanical mechanism. Specifically, a worker manually controls the paper feed mechanism. Once the paper arrives at the stacking station, the feed mechanism is paused and the paper is manually pushed onto the stacking plate to complete the stacking. This stacking method is extremely inefficient and requires significant labor and time.

[0004] To solve the above problems, the Chinese utility model with patent number CN202122502482.9 discloses an integrated device for conveying, stacking and bundling paper, including a paper stacking mechanism that receives a paper conveying mechanism, and also includes a paper pushing mechanism and a packaging mechanism; wherein the paper stacking mechanism includes a collecting plate for stacking paper and a pushing knife mechanism that slides relative to the collecting plate; the pushing knife mechanism includes a pushing plate, and also includes a reciprocating pushing mechanism that drives the pushing plate to slide back and forth toward the collecting plate; after individual sheets of paper are conveyed by the paper conveying mechanism, they vertically enter the pushing plate of the paper stacking mechanism, and after receiving the paper, the pushing plate quickly pushes the paper horizontally to the relatively arranged collecting plate, thereby stacking the paper into a long strip structure. When a certain number of papers are stacked, the paper pushing mechanism transfers the paper to the next process.

[0005] In the above scheme, individual sheets of paper are fed by a pusher mechanism through a paper conveyor mechanism and then vertically onto a push plate of a paper stacking mechanism, where they are stacked into long strips. Once a certain number of sheets are stacked, the paper pusher mechanism moves the sheets to the next process. However, due to direct friction between the ends of the sheets and the plate, these ends can be damaged when pushed to the next process, resulting in insufficient paper and affecting subsequent production quality. Summary of the Invention

[0006] The object of the present invention is to provide a paper stacking platform for a paper bundling machine in view of the deficiencies in the prior art.

[0007] To achieve the above object, the technical solution of the present invention is as follows:

[0008] A paper stacking platform of a paper bundling machine, including a receiving platform for stacking paper, wherein a conveyor belt assembly for conveying paper forward is arranged along the length direction of the receiving platform, and a paper guide assembly for guiding falling paper is provided at one end of the receiving platform; the paper guide assembly includes a drop roller for rolling and guiding the paper falling to the receiving platform, and a drop swing member for tilting and guiding the dropped paper;

[0009] A fork paper separation mechanism is provided at the bottom of the receiving table, the fork paper separation mechanism includes a first fork member and a second fork member and a fork driving mechanism that drives the first fork member and the second fork member to move laterally, the first fork member includes a first fork seat and a plurality of first fork rods that can be longitudinally slidably mounted on the first fork seat and can be inserted into the stacked paper for separation, the second fork member includes a second fork seat and a plurality of second fork rods that can be longitudinally slidably mounted on the second fork seat and can be inserted into the stacked paper for separation;

[0010] A plywood loading mechanism is provided on the top of the collecting table, and the plywood loading mechanism includes a loading platform for stacking protective plywood. The protective plywood can be continuously moved along the loading platform. A pushing plate mechanism is provided at one end of the loading platform to push the protective plywood of the loading platform one by one to the two ends of the pile of paper. The pushing plate mechanism includes a lifting block that can move longitudinally, and the lifting block is equipped with a limit block to prevent the protective plywood from falling, and a suction component located at the bottom of the limit block that can adsorb the protective plywood.

[0011] The beneficial effects of the present invention are as follows: the paper to be stacked is transported and then falls onto the receiving platform for stacking. When the paper is falling, the falling rolling member cooperates with the falling paper to guide the falling paper, thereby improving the stability of the paper falling. After the paper falls onto the receiving platform, in order to prevent the paper from tilting forward and collapsing, the falling swinging member guides the paper to tilt backward, thereby preventing the paper from tilting forward and collapsing, thereby improving the quality of subsequent stacking of the paper.

[0012] When stacking papers, the feeding platform and the push plate mechanism cooperate to firstly attract the outermost protective splint with the suction part, and the limit block pushes the protective splint out to guide the stacked papers. After the papers are stacked to the required number, the feeding platform and the push plate mechanism cooperate to push the protective splint out to support the other end of the stacked papers, so that both ends of the stacked papers are protected by the protective splint, and the papers will not be damaged in the subsequent bundling, which can effectively protect the papers and improve the bundling quality of the papers.

[0013] When stacking papers, the first fork member is inserted to the outermost side of the papers to be stacked and presses against the papers, and continuously moves laterally to guide the papers to be stacked together, then the first fork member retracts and continues to stack, and after the required number of sheets are stacked, the first fork member and the second fork member approach each other and rise to the disconnection point at the same time, and the first fork member continues to move laterally to guide the papers to be stacked together; the second fork member moves laterally to move the stacked papers to one side for packaging; the stacked papers can be well separated and dispersed without collapse, and the stacked papers can be separated without stopping the machine, thereby improving the efficiency of paper stacking.

[0056] The present invention is described in detail below with reference to the accompanying drawings.

[0057] like Figure 1-11 As shown, a paper stacking platform of a paper bundling machine.

[0058] The utility model comprises a receiving platform 1 for supporting paper, the receiving platform 1 is provided with an installation panel 12, the installation panel 12 is composed of a left panel 121 and a right panel 122 arranged with a gap, the receiving platform 1 is provided with a conveyor belt assembly 123 for conveying the paper forward along the length direction, and a paper guide assembly 11 for guiding the falling paper is provided at one end of the receiving platform 1; the paper guide assembly 11 includes a blanking roller 111 for rolling and guiding the paper falling to the receiving platform 1, and a blanking swinging member 115 for tilting and guiding the paper after blanking.

[0059] The blanking rolling element 111 includes a first rotating shaft 112, and the first rotating shaft 112 is axially nested with a plurality of first swing bars 113 that swing as the first rotating shaft 112 rotates. The end of the first swing bar 113 is installed with a first rolling wheel 114 that can rotatably roll with the falling paper guide; the first rotating shaft 112 is driven by a motor to rotate, so that the first swing bar 113 nested in the first rotating shaft 112 swings accordingly, and the first rolling wheel 114 installed at the end of the first swing bar 113 changes its position accordingly, which can guide the paper to fall forward or drop backward, thereby changing the blanking position.

[0060] The blanking swing member 115 includes a second rotating shaft 116, and the second rotating shaft 116 is axially nested with a plurality of second swing bars 117 that swing as the second rotating shaft 116 rotates. The end of the second swing bar 117 is formed with a guide bar 118 perpendicular to the first swing bar 113, and the second rotating shaft 116 is also nested with a driving bar 119; after the paper is dropped to the receiving table 1, the back of the paper is against the guide bar 118. In order to prevent the paper from tilting forward and collapsing, the blanking swing member 115 works, driving the driving bar 119 to swing, so that the second rotating shaft 116 swings, driving the guide bar 118 to swing, guiding the paper to tilt backward, preventing the paper from tilting forward and collapsing, and improving the quality of subsequent stacking of the paper.

[0061] The conveyor belt assembly 123 includes two or more belt conveyors 124 arranged along the length of the receiving platform 1. Each belt conveyor 124 is equipped with a belt conveyor pulley 126. One end of the belt conveyor 124 extends toward one end of the receiving platform 1. A support bar 125 is formed at one end of the receiving platform 1 to support the extended belt conveyor 124. The receiving platform 1 also has a paper stopper 13 that moves along the length of the conveyor belt assembly 123. Papers, guided by the rolling element 111 and the swinging element 115, fall onto the receiving platform 1 and are stacked. After a portion of the paper is stacked, the paper stopper 13 moves to the front end of the paper to stop it. This allows one end of the stacked paper to be held against the stopper 13, while the other end continues to stack under the movement of the belt conveyor 124. The paper stopper 13 also moves accordingly to accommodate the stacking process, allowing the paper to be stacked to the desired length.

[0062] The paper retainer 13 includes a top retainer 131 and a bottom retainer 132 arranged with a longitudinal gap. After stacking, a push plate can be used to push the paper on the paper retainer 13 horizontally through the gap between the top retainer 131 and the bottom retainer 132 to push it away for bundling without affecting the position of the paper retainer 13. The paper retainer 13 also includes a top connecting plate 133 connected to the back of the top retainer 131 and a bottom connecting plate 134 connected to the bottom retainer 132. The top connecting plate 133 and the bottom connecting plate 134 are integrally formed and connected, making the top retainer 131 and the bottom retainer 132 more stable and less likely to collapse.

[0063] A paper stop moving member 130 is provided at the bottom of the receiving platform 1 to drive the paper stop seat 13 to move. The paper stop moving member 130 includes a bottom linear module 135 arranged along the length of the receiving platform 1. A bottom sliding seat 136 is mounted on the sliding end of the bottom linear module 135. The bottom sliding seat 136 is provided with a bottom connecting member connected to the paper stop seat 13. The bottom connecting member includes an L-shaped plate 137 mounted on the top of the bottom sliding seat 136. The bottom baffle 132 is connected to a bottom mounting plate 138. A pair of parallel and spaced bottom connecting blocks 139 are mounted at the bottom of the bottom mounting plate 138. The two bottom connecting blocks 139 are respectively connected perpendicularly to the L-shaped plate 137.

[0064] When the paper stopper 13 moves, the bottom linear module 135 works, and the bottom connecting part is driven to move through the bottom sliding seat 136. The L-shaped plate 137 of the bottom connecting part cooperates with the bottom connecting block 139 to move along the length direction of the material receiving table 1. Since the top of the bottom connecting block 139 is connected to the bottom mounting plate 138 installed at the bottom of the bottom baffle 132, it can drive the paper stopper 13 to move in the length direction of the material receiving table 1.

[0065] The gap between the left panel 121 and the right panel 122 is a sliding drive groove 127 for the bottom connecting block 139 at the bottom of the bottom mounting plate 138 to slide. The left panel 121 and the right panel 122 are arranged in parallel and spaced apart in the horizontal direction. A cover plate 128 is installed on a part of the sliding drive groove 127. The cover plate 128 is formed with a cover groove 129 along the length direction for the bottom connecting block 139 to slide. A part of the sliding drive groove 127 is blocked by the cover plate 128. The cover groove 129 provided on the cover plate 128 can be used for the reciprocating sliding bottom connecting block 139 to slide, without affecting the operation of the paper stop moving member 130.

[0066] A splint loading mechanism 2 is provided on the top of the receiving table 1, including a loading platform 21 for stacking protective splints 217. The protective splints 217 can move continuously along the loading platform 21. The loading platform 21 includes an inclined platform plate 211 for stacking multiple protective splints 217 in an upright posture. A smooth component 210 is arranged on the platform plate 211 along the length direction, which is in rolling cooperation with the protective splints 217 and allows the protective splints 217 to slide along the platform plate 211. Multiple protective splints 217 are fitted with each other in an upright posture and placed on the platform plate 211 with the smooth component 210. Since the platform plate 211 is arranged at an angle, the stacked protective splints 217 will slide continuously under the influence of gravity for the protective splints 217 to be loaded. There is no need to use other mechanisms to push the plates, which can reduce costs.

[0067] Specifically, there are three or more flow assemblies 210, each comprising a flow strip 212 arranged along the length of a platform plate 211. These strips 212 are provided with mounting slots 218 along their length, and second rollers 213 are mounted at intervals along the length of the mounting slots 218, rotatably and rollingly engaging the bottom edge of protective cleats 217. Furthermore, a top plate 214 is provided on the platform plate 211 to prevent the protective cleats 217 from collapsing. This top plate 214 includes an inclined plate 215 for supporting the end of the protective cleats 217. A gravity pusher 216 is mounted at the bottom of the inclined plate 215, slidably engaging the flow assemblies 210.

[0068] Preferably, the stacked protective splints 217 are placed on a platform plate 211 on which a plurality of flow components 210 are installed. When loading materials, the protective splints 217 will continuously slide along the flow components 210. The second rolling wheel 213 of the flow bar 212 rolls with the bottom edge surface of the protective splint 217. The protective splint 217 will slide due to gravity, thereby loading materials one by one. The stacked protective splints 217 are supported by the top plate 214 at the tail end. The tilting angle of the tilting plate 215 is the same as that of the protective splint 217, which can better support the protective splint 217 at an angle. After the protective splints 217 load materials one by one, the gravity push block 216 slides with the flow component 210 and always keeps in contact with the protective splint 217, thereby achieving oblique support and preventing the protective splint 217 from collapsing and affecting material loading.

[0069] A pushing plate mechanism 22 is provided at one end of the loading platform 21 to push the protective splints 217 of the loading platform 21 one by one to both ends of the pile of paper. The pushing plate mechanism 22 includes a longitudinally movable lifting block 23. The pushing plate mechanism 22 also includes a pushing plate frame 220 installed at the end of the platform plate 211. The pushing plate frame 220 is equipped with a longitudinally arranged pushing plate driving member. The driving end of the pushing plate driving member is equipped with a longitudinally movable pushing plate driving seat 224. The pushing plate driving seat 224 is connected to the lifting block 23. The lifting block 23 is equipped with a limit block 232 to prevent the protective splint 217 from falling, and a suction member 233 located at the bottom of the limit block 232 for adsorbing the protective splint 217. When the papers are stacked, the feeding platform 21 and the pushing plate mechanism 22 cooperate to firstly absorb the outermost protective splint 217 through the suction part 233, and the limit block 232 pushes out the protective splint 217 to guide the stacked papers. After the papers are stacked to the required number, the feeding platform 21 and the pushing plate mechanism 22 cooperate to push out the protective splint 217 to support the other end of the stacked papers, so that both ends of the stacked papers are protected by the protective splint 217, and the papers will not be damaged in the subsequent bundling, which can effectively protect the papers and improve the bundling quality of the papers.

[0070] The push plate frame 220 includes a plurality of transverse aluminum profiles 221 arranged transversely and a longitudinal aluminum profile 222 arranged longitudinally. The push plate driving component is a longitudinal linear module 223 installed perpendicular to the transverse aluminum profile 221. The power component of the longitudinal linear module 223 is a servo motor. The longitudinal linear module 223 is formed with a longitudinal guide column 225 along the length direction. The push plate driving seat 224 is longitudinally formed with a longitudinal guide groove 226 that slides with the longitudinal guide column 225.

[0071] The horizontal aluminum profile 221 and the longitudinal aluminum profile 222 are spliced ​​with each other by welding to form a push plate frame 220 with a frame-shaped structure. The push plate frame 220 is also connected to the outer end of the platform plate 211, and has good stability. Driven by the longitudinal linear module 223, the lifting block 23 slides with the longitudinal guide column 225 of the longitudinal module through the longitudinal guide groove 226, so that the lifting block 23 can move longitudinally. During the longitudinal movement, the limit block 232 on the lifting block 23 abuts against the protective splint 217 to prevent the protective splint 217 from falling. When the lifting block 23 continues to rise and does not contact the protective splint 217, the protective splint 217 contacts the suction piece 233 at the bottom of the limit block 232, and the protective splint 217 is adsorbed by the suction piece 233. Then the lifting block 23 descends and pushes a protective splint 217 downward to realize loading one by one.

[0072] The bottom of the lifting block 23 is formed with multiple spaced lifting bars 231. Suction members 233 are mounted on these bars. These multiple suction members 233 can simultaneously suction the protective plates 217, improving suction stability. The distance between the outer end of the stopper 232 and the end of the loading platform 21 is less than the thickness of a single protective plate 217. The distance between the outer end of the suction member 233 and the end of the loading platform 21 is greater than the thickness of a single protective plate 217 but less than the thickness of two protective plates 217.

[0073] When the lifting block 23 is lifted up and no longer contacts the protective splint 217, the entire stack of protective splints 217 slides a distance of one protective splint 217, and the outermost protective splint 217 contacts the suction piece 233 at the bottom of the limit stop 232. One end face of the protective splint 217 contacts the suction piece 233, and the other end face contacts the other protective splint 217. Then the lifting block 23 descends, and the bottom surface of the limit stop 232 pushes one protective splint 217 downward. After being pushed out, the second protective splint 217 slides with the limit stop 232 and will not fall off the platform plate 211. Therefore, the number of protective splints 217 pushed downward each time is only one, and they are pushed down one by one.

[0074] A fork paper separation mechanism 3 is provided at the bottom of the receiving platform 2. The fork paper separation mechanism 3 includes a first fork member 31 and a second fork member 33. The paper to be stacked is stacked on the horizontally arranged receiving platform 2 so that the belt conveyor can continuously move and fit the paper.

[0075] The first fork member 31 includes a first fork seat 311 and a plurality of first fork rods 324 that can be longitudinally slidably installed on the first fork seat 311 and can be inserted into the stacked paper for separation. The first fork seat 311 includes a first top seat 312 and a first bottom seat 313. The first top seat 312 and the first bottom seat 313 are arranged at intervals. A longitudinally arranged first rack condition 328 is installed between the first top seat 312 and the first bottom seat 313. The first fork rod 324 moves longitudinally along the first rack condition 328.

[0076] The two adjacent first fork rods 324 are arranged at equal distances, and the first fork member 31 also includes a first connecting plate 314 connecting all the first fork rods 324, wherein the first top seat 312 is installed with a first guide plate 315 for guiding the first fork rod 324 through, and the first guide plate 315 is formed with a first guide hole 316 coaxially aligned with the first fork rod 324; when the first fork rod 324 moves longitudinally along the first rack condition 328, the first fork rod 324 slides through the first guide hole 316 of the first guide plate 315 to achieve lifting, so that the first fork rod 324 will not shift, and can accurately separate the stacked paper, thereby improving the stability and accuracy of separation and reducing the occurrence of paper damage.

[0077] A longitudinally arranged first sliding shaft 317 is installed between the first top seat 312 and the first bottom seat 313, and a first sliding seat 318 is slidably installed on the first sliding shaft 317. The first sliding seat 318 is installed with a transversely arranged first lifting connecting rod 32, and the first lifting connecting rod 32 is installed with a first lifting drive plate 321. The first lifting drive plate 321 is installed with a transversely arranged first connecting shaft 322. Both ends of the first connecting shaft 322 are respectively installed with a first gear member 323 that meshes with the first rack condition 328 for transmission; the first fork rod 324 is formed with a first meshing groove 325 that meshes with the first gear member 323 for transmission along the length direction; in this embodiment, it is necessary to drive the first shift fork rod 324 to engage with the first gear member 323. When the fork rod 324 is raised or lowered, the first lifting connecting rod 32 is raised or lowered along the first sliding seat 318 through the first sliding seat 318, and the first gear member 323 is installed on the first lifting connecting rod 32 through the first lifting driving plate 321 and the first connecting shaft 322. The first gear member 323 is engaged with the first gear condition 328 installed between the first top seat 312 and the first bottom seat 313, so that the first gear member 323 can rotate. At the same time, the first gear member 323 is engaged with the first tooth groove 325 of the first fork rod 324, so that the first fork rod 324 can move in the vertical direction, which can accurately separate the stacked paper sheets, thereby improving the stability and accuracy of the separation.

[0078] Similarly, the second fork member 33 includes a second fork seat 331 and a plurality of second fork rods 344 that are longitudinally slidably mounted on the second fork seat 331 and can be inserted into a stack of paper sheets for separation. Adjacent second fork rods 344 are equidistantly spaced. The second fork seat 331 includes a second top seat 332 and a second bottom seat 333, which are spaced apart. A longitudinally arranged second rack member 348 is mounted between the second top seat 332 and the second bottom seat 333. The second fork rods 344 move longitudinally along a second sliding axis 337.

[0079] The two adjacent second fork rods 344 are arranged at equal distances, and the second fork member 33 also includes a second connecting plate 334 connecting all the second fork rods 344, wherein the second top seat 332 is installed with a second guide plate 335 for guiding the second fork rod 344 through, and the second guide plate 335 is formed with a second guide hole 336 coaxially aligned with the second fork rod 344; when the second fork rod 344 moves longitudinally along the second rack condition 348, the second fork rod 344 slides through the second guide hole 336 of the second guide plate 335 to achieve lifting, so that the second fork rod 344 will not shift, and can accurately separate the stacked paper, thereby improving the stability and accuracy of separation and reducing the occurrence of paper damage.

[0080] A longitudinally arranged second sliding shaft 337 is installed between the second top seat 332 and the second bottom seat 333, and a second sliding seat 338 is slidably installed on the second sliding shaft 337. The second sliding seat 338 is installed with a transversely arranged second lifting connecting rod 34, and the second lifting connecting rod 34 is installed with a second lifting drive plate 341. The second lifting drive plate 341 is installed with a transversely arranged second connecting shaft 342, and both ends of the second connecting shaft 342 are respectively installed with second gear parts 343 that mesh with the second gear condition 348 for transmission. In this embodiment, when it is necessary to drive the second fork rod 344 to rise and fall, the second lifting connecting rod 34 rises and falls along the second sliding seat 338 through the second sliding seat 338, and the second gear member 343 is installed on the second lifting connecting rod 34 through the second lifting driving plate 341 and the second connecting shaft 342. The second gear member 343 is engaged with the second gear condition 348 installed between the second top seat 332 and the second bottom seat 333 for transmission, so that the second gear member 343 can rotate. At the same time, the second gear member 343 is engaged with the second tooth groove 345 of the second fork rod 344 for transmission, so that the second fork rod 344 can move in the vertical direction, which can accurately separate the stacked paper sheets, thereby improving the stability and accuracy of the separation.

[0081] After being conveyed, the papers are stacked. When stacking is required, the first fork member 31 is inserted to the outermost side of the papers to be stacked and presses against the papers, and continuously moves laterally to guide the papers to be stacked together. After the outer end of the papers is pressed and guided by the baffle, the first fork member 31 retracts. After the papers are stacked to the required number of sheets, the belt conveyor of the stacking platform accelerates, and gaps appear in the entire stack of papers. The first fork member 31 and the second fork member 33 approach each other and rise to the gap at the same time. The first fork member 31 continues to move laterally to guide the papers to be stacked together; the second fork member 33 moves laterally to move the stacked papers to one side for packaging; the stacked papers can be well separated and dispersed without collapse, and the stacked papers can be separated without stopping, thereby improving the efficiency of paper stacking.

[0082] The fork paper separation mechanism 3 also includes a fork driving mechanism 35 that drives the first fork member 31 and the second fork member 33 to move horizontally. The fork driving mechanism 35 includes a horizontal module 351 arranged along the first fork member 31 and the second fork member 33 in a horizontal movement direction. The horizontal module 351 is slidably installed with a horizontally sliding driving sliding seat 352, one of which is provided with a first longitudinal driving member 353 that drives the first fork rod 324 to move longitudinally, and the other driving sliding seat 352 is provided with a second longitudinal driving member 354 that drives the second fork rod 344 to move longitudinally. The first lifting connecting rod 32 is connected to the first longitudinal driving member 353 of one of the driving sliding seats 352; the second lifting connecting rod 34 is connected to the second longitudinal driving member 354 of the other driving sliding seat 352.

[0083] The first longitudinal driving member 353 and the second longitudinal driving member 354 are both longitudinally arranged linear modules, wherein the sliding end of one linear module is installed with a first lifting connecting plate 355 connected to the first lifting connecting rod 32, and the sliding end of the other linear module is installed with a second lifting connecting plate 356 connected to the second lifting connecting rod 34.

[0084] Preferably, there are two transverse modules 351, which are arranged parallel to each other and spaced apart. When the first fork member 31 and the second fork member 33 need to move, the transverse module 351 works to drive the driving sliding seat 352 to move transversely. One of the driving sliding seats 352 is connected to the first lifting connecting rod 32 by the lifting and lowering coordination of the linear module with the first lifting connecting plate 355; one of the driving sliding seats 352 is connected to the second lifting connecting rod 34 by the lifting and lowering coordination of the linear module with the second lifting connecting plate 356; thereby driving the first fork member 31 and the second fork member 33 to move transversely and longitudinally, guiding the stacking of paper and separating the stacked paper.

[0085] The first fork seat 311 of the first fork member 31 is installed with a first guide seat 326, and the first guide seat 326 is formed with a first drive hole 327 that passes through horizontally. The second fork seat 331 of the second fork member 33 is installed with a second guide seat 346, and the second guide seat 346 is formed with a second drive hole 347 that is coaxially aligned with the first drive hole 327. A limiting shaft 357 is slidably passed through the first drive hole 327 and the second drive hole 347 between the first guide seat 326 and the second guide seat 346.

[0086] When the first fork member 31 and the second fork member 33 move laterally, the first fork member 31 and the second fork member 33 will move relative to each other. When moving, they are limited by the limiting shaft 357 between the first guide seat 326 and the second guide seat 346. The limiting shaft 357 slides with the first drive hole 327 and the second drive hole 347 respectively, so that the first fork member 31 and the second fork member 33 move laterally along the limiting shaft 357 at the same time, and the stability and accuracy of the movement are better.

[0087] Working process: After being conveyed, the papers continuously fall onto the receiving table 1. After the first paper falls in, the second paper is inserted into the back of the first paper. The belt conveyor 124 on the receiving table 1 works, and the subsequent papers are continuously inserted to achieve stacking. At this time, the first fork member 31 works, rises and presses against the first paper, and moves laterally at the movement speed of the belt conveyor 124 to ensure that the papers will not collapse and are continuously stacked; the paper stopper moves to the falling position of the protective splint 217 of the splint feeding mechanism 2. When the first fork member 31 approaches the paper stopper seat 13, the protective splint 217 falls and falls just between the first fork member 31 and the paper stopper seat 13 and will not fall. Then the first fork member 31 descends and retracts, and the outermost The paper at the end is collected; when the number of paper stacks reaches the required number after counting, the speed at which subsequent papers fall will be reduced, so that there is a gap in the continuous papers, and the gap is behind the collecting table 1. The protective clamping plate 217 of the clamping feeding mechanism 2 falls to the gap, and the first fork member 31 and the second fork member 33 are attached to each other and raised at the same time to be inserted into the gap area, wherein the second fork member 33 cooperates with the movement speed of the belt conveyor 124 to move the counted papers forward in piles, so that the two ends of the stacked papers are protected by the protective clamping plate 217, which can effectively protect the papers during subsequent bundling and transfer, and the first fork member 31 stacks and collects the new papers again, and this cycle is repeated to achieve non-stop stacking and collection of papers.

[0088] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.
