DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application will be further described below in combination with specific embodiments.

[0024] As Figures 1 to 8As shown, the present application provides a technical solution: a kind of automatic stacking machine for paper roll production, including base table 1, the top of base table 1 is fixedly installed with conveying mechanism 2, conveying mechanism 2 is conveyed with paper roll package 13 on the surface, one end of conveying mechanism 2 is provided with stagnation table 3, the other side of stagnation table 3 is provided with moving table 5, the top of moving table 5 is fixedly connected with stacking table 6, moving table 5 is slidably connected between base table 1, the upper portion of stagnation table 3 is provided with clamping assembly, clamping assembly includes two movable clamping plates 4, the upper portion of clamping plate 4 is provided with lifting assembly for lifting two clamping plates 4, one side of moving table 5 is provided with pull-in assembly, pull-in assembly is used to drive moving table 5 to move forward and advance, one end of stagnation table 3 is provided with transmission assembly for driving stagnation table 3 to rotate, the two sides of moving table 5 are provided with clamping assembly for locking the position of moving table 5.

[0025] When working: first, paper roll package 13 is sequentially conveyed by conveying mechanism 2, after a plurality of paper roll packages 13 are conveyed to the surface of stagnation table 3, they are first stacked together on the surface of stagnation table 3 transversely;Then, two clamping plates 4 are moved close to each other by clamping assembly, gradually close to and contact the side of a plurality of paper roll packages 13, and a certain clamping force is applied to form clamping wrapping on the side of paper roll package 13;Then, two clamping plates 4 and clamped paper roll package 13 are lifted together by lifting assembly, so that paper roll package 13 leaves the surface of stagnation table 3 and is no longer supported by it;During the lifting of clamping plate 4 and paper roll package 13, pull-in assembly makes moving table 5 and stacking table 6 move forward and advance, when clamping plate 4 and paper roll package 13 reach the highest position, moving table 5 drives stacking table 6 to move just below a plurality of paper roll packages 13, and when moving table 5 moves forward, transmission assembly makes stagnation table 3 rotate to change its position state, so as to avoid affecting the movement path of clamping plate 4 to place paper roll package 13 above stacking table 6; When moving table 5 and stacking table 6 move below clamped paper roll package 13, clamping assembly locks the current position of moving table 5 and stacking table 6, then lifting assembly drives clamping plate 4 to descend, so that paper roll package 13 is stably placed on the upper surface of stacking table 6, after placing paper roll package 13, clamping plate 4 moves away from each other and separates, and no longer applies clamping force to paper roll package 13, so that paper roll package 13 is stably placed on stacking table 6 for stacking, as the stacking height on the surface of stacking table 6 gradually increases, the distance of clamping plate 4 descending each time needs to be adaptively adjusted; After each layer of stacking work is completed, the locking of clamping assembly on the position of moving table 5 and stacking table 6 is cancelled, moving table 5 and stacking table 6 move reversely to restore to the original position, when resetting, transmission assembly makes stagnation table 3 return to the original position state, and the next group of paper roll packages 13 conveyed by conveying mechanism 2 is received again, so as to circulate until the stacking height on the surface of stacking table 6 reaches the appropriate height, then stacking table 6 is removed from above moving table 5, and a new stacking table 6 is replaced to continue the stacking work; Through the above embodiment, during the lifting of the clamp plate 4 and the paper roll package 13, the pulling assembly drives the moving table 5 and the stacking table 6 to move forward, and when the clamp plate 4 and the paper roll package 13 are lifted to the highest position, the moving table 5 drives the stacking table 6 to move just below the plurality of paper roll packages 13, thereby providing a position guarantee for accurately placing the paper roll package 13 on the stacking table 6. After the paper roll package 13 is clamped, it does not need to be turned and placed on the stacking table 6, which solves the problem that the existing technology needs to be turned and is prone to sliding due to centrifugal force. After the paper roll package 13 is clamped, only a simple lifting movement is needed to realize the stacking process of the paper roll package 13; through the transmission assembly, when the moving table 5 moves forward, the transmission assembly drives the stationary table 3 to rotate, changes the position state of the stationary table 3, avoids the influence of the stationary table 3 on the movement path of the clamp plate 4 lowering the paper roll package 13 onto the stacking table 6 in the original position, ensures that the paper roll package 13 can be smoothly placed from the clamp plate 4 to the stacking table 6, and guarantees the smooth progress of the stacking process; through the clamping assembly, when the moving table 5 and the stacking table 6 move below the clamped paper roll package 13, the clamping assembly locks the current position of the moving table 5 and the stacking table 6, thereby preventing the paper roll package 13 from sliding or stacking irregularly due to the movement of the stacking table 6 during the process of the lifting assembly driving the clamp plate 4 to lower the paper roll package 13 onto the stacking table 6, ensuring that the paper roll package 13 can be accurately and stably placed on the stacking table 6, and making the stacked paper roll package 13 more stable.

[0026] As shown in Figures 3 to 5 , the clamping assembly further comprises a fixed inner groove seat 7, the inner wall of the fixed inner groove seat 7 is symmetrically and slidably connected with an inner sliding block 8, a hydraulic cylinder 9 is fixedly installed at the center position of the inner wall of the fixed inner groove seat 7, and the two ends of the hydraulic cylinder 9 are respectively fixedly connected with one side of the two inner sliding blocks 8. The bottom of the inner sliding block 8 is respectively fixedly connected with the top of the clamp plate 4.

[0027] When working: in the initial state, the two clamp plates 4 are respectively located on the two sides of the stationary table 3 and do not contact the side edges of the paper roll package 13, which will not affect the horizontal stacking of the paper roll package 13 on the surface of the conveying mechanism 2; when a group of paper roll packages 13 need to be clamped, the hydraulic cylinder 9 is started to make it contract, at this time, the two inner sliding blocks 8 will move relatively close along the inner wall of the fixed inner groove seat 7, thereby driving the two clamp plates 4 to move close to each other to clamp and wrap the side edges of the plurality of paper roll packages 13; in this process, the clamping force of the clamp plate 4 needs to be reasonably controlled to prevent the paper roll package 13 from deforming and affecting the stability of subsequent stacking.

[0028] As shown in Figures 3 to 5As shown, the upper part of the fixed inner groove seat 7 is fixedly connected with a fixed plate 10, the upper part of the fixed plate 10 is provided with a top plate frame 11, the top of the top plate frame 11 is fixedly connected with a motor 12, the output shaft of the motor 12 is fixedly connected with the top of the fixed plate 10, and the output shaft of the motor 12 penetrates and is rotatably connected to the inner wall of the top plate frame 11.

[0029] When it is needed to lift the paper roll package 13 clamped on the clamping plate 4 away from the surface of the stagnation table 3, the lifting assembly is started to lift the top plate frame 11, thereby driving the clamping plate 4 and the paper roll package 13 to rise together; when it is needed to place the paper roll package 13 on the stacking table 6, the lifting assembly controls the top plate frame 11 to descend, so as to realize the accurate placement of the paper roll package 13; at the same time, through the motor 12 arranged, the rotating function of the clamping plate 4 can be realized, so that the paper roll package 13 can be placed staggeredly in each layer of stacking, that is, the placement position of the paper roll package 13 in the upper layer is offset from the lower layer, and the staggered stacking mode increases the friction and mutual supporting force between the paper roll packages 13, thereby effectively improving the stability and firmness of the stacking.

[0030] As shown in Figures 5 to 6 The lifting assembly includes two electric guide rails 15, which are symmetrically and fixedly connected to the upper part of the base table 1, the inner side of the electric guide rail 15 is slidably connected with an electric sliding block 14, the top of the electric sliding block 14 is fixedly connected with the bottom side of the top plate frame 11, the inner wall of the electric guide rail 15 is fixedly connected with a fixed rod 16, and the inner wall of the electric sliding block 14 is slidably connected with the outer wall of the electric guide rail 15.

[0031] When it is needed to lift the clamping plate 4 and the paper roll package 13 clamped by the clamping plate 4, the electric guide rail 15 is started, and the electric guide rail 15 usually has a corresponding driving device (such as a motor, a lead screw, etc., which is not shown in detail in the figure, but it is a common structure of the electric guide rail) inside, which makes the electric sliding block 14 slide linearly upward along the inner wall of the electric guide rail 15 under the action of the driving force. Since the inner wall of the electric sliding block 14 is slidably connected with the outer wall of the electric guide rail 15, and the fixed rod 16 on the inner wall of the electric guide rail 15 plays a certain guiding and stabilizing role, it ensures that the electric sliding block 14 can stably and accurately rise along the predetermined track without deviation or shaking.

[0032] As shown in Figures 5 to 6 The pulling assembly includes two pull ropes 19, the two sides of the moving table 5 and the bottom of the electric sliding block 14 are fixedly connected with a limiting rod 17, the outer wall of the limiting rod 17 is rotatably connected with a pulling circular block 18, and the two ends of the pull rope 19 are fixedly connected with the outer walls of the two pulling circular blocks 18.

[0033] When working: in the initial state, the clamping plate 4 is located on both sides of the stationary table 3, at this time the pull rope 19 is in a straight state, and the moving table 5 is located below the stationary table 3. When the electric sliding block 14 moves upward along the inner wall of the electric guide rail 15, the clamping plate 4 will lift a group of paper rolls 13 upward, and in the process of moving upward of the electric sliding block 14, since one end of the pull rope 19 is fixedly connected to the corresponding pull block 18 of the limiting rod 17 at the bottom of the electric sliding block 14, and the other end is fixedly connected to the corresponding pull block 18 of the limiting rod 17 at the side of the moving table 5, as the electric sliding block 14 continuously rises, the pull rope 19 is elongated in the vertical direction, and then a horizontal pulling force is generated on the moving table 5 through the upward stretching action; in the process of pulling the moving table 5 by the pull rope 19, the pull block 18 will be adaptively articulated on the outer wall of the limiting rod 17, so as to ensure that the pulling force of the pull rope 19 can be smoothly transmitted, so that the moving table 5 can move in the expected direction.

[0034] As shown in Figure 4 , the bottom of the moving table 5 is fixedly connected with a plurality of pulleys 20, and the surface of the base table 1 is provided with pulley grooves 21, and the pulleys 20 are in sliding connection with the inner walls of the pulley grooves 21.

[0035] When working: when the pull rope 19 generates a pulling force due to the movement of the electric sliding block 14 and drives the moving table 5 to move, the pulley 20 will stably roll along the inner wall of the pulley groove 21. The inner walls on both sides of the pulley groove 21 provide a horizontal constraint boundary for the pulley 20, so that the pulley 20 can only roll in the straight line direction specified by the pulley groove 21, thereby ensuring that the moving table 5 can accurately move along the predetermined horizontal path.

[0036] As shown in Figures 3 to 4 , the transmission assembly includes a bearing seat 22, the shaft rod outer wall of the bearing seat 22 is fixedly connected with one end of the stationary table 3, the shaft rod both ends of the bearing seat 22 are fixedly connected with a gear 23, both sides of the moving table 5 are fixedly connected with a connecting plate 25, the top of the connecting plate 25 is fixedly connected with a rack plate 24, the gear teeth of the gear 23 can be intermeshed with the gear teeth of the rack plate 24, and the number of gear teeth of the rack plate 24 is one fourth of the number of gear teeth of the gear 23.

[0037] When working: in the initial state, the stationary table 3 maintains a horizontal state. Because the shaft of the bearing seat 22 needs to rotate with a large force, this feature makes the stationary table 3 still able to maintain a stable horizontal state even if it bears multiple paper roll packages 13, and the overall mass of the paper roll packages 13 is relatively light, providing a smooth platform for subsequent paper roll package 13 processing operations. When the moving table 5 moves in the horizontal direction, the rack plate 24 at the top of the two side connecting plates 25 also moves synchronously with the movement of the moving table 5. Because the teeth of the gear 23 can be engaged with the teeth of the rack plate 24, when the rack plate 24 moves, its teeth will sequentially contact the teeth of the gear 23 and generate a mutual force, thereby driving the gear 23 to start rotating. The gear 23 drives one end of the stationary table 3 to hinge downward around the shaft of the bearing seat 22. Because the number of teeth of the rack plate 24 is one-fourth of the number of teeth of the gear 23, the stationary table 3 will rotate 90 degrees, just overlapping the inner wall of the bearing seat 22, so that during stacking, the stationary table 3 does not affect the placement of the paper roll packages 13 and the stacking surface of the stacking table 6. When the stacking surface is high, the stationary table 3 cannot move directly below the clamping plate 4 due to its influence.

[0038] As shown in Figures 7 to 8 , the clamping assembly includes two side connecting rods 26 fixedly connected to the two sides of the moving table 5. The outer wall of the side connecting rod 26 is slidingly connected with a clamping block 27. A restoring spring 28 is fixedly connected between one side of the clamping block 27 and the side of the moving table 5. The clamping block 27 is in contact with a limiting plate 29. One end of the limiting plate 29 is provided with a recess 30 which is mutually adapted in shape and size with the clamping block 27. The inner walls of the limiting plate 29 and the recess 30 are provided with a side sliding groove 31. The outer wall of the side connecting rod 26 is slidingly connected with the inner wall of the side sliding groove 31 and is mutually adapted.

[0039] When working: in the initial state, the clamping block 27 is tightly attached to one side of the limiting plate 29 under the extrusion of the limiting plate 29. Such extrusion makes the restoring spring 28 in a compressed state, accumulating a certain elastic potential energy. When the moving table 5 moves along the horizontal direction, the clamping block 27 always moves tightly attached to the inner side of the limiting plate 29. In this process, the restoring spring 28 always exerts a spring force on the clamping block 27, trying to make the clamping block 27 return to the initial position not extruded. However, the limitation of the limiting plate 29 makes the clamping block 27 only move along the track inside the limiting plate 29. When the moving table 5 moves to the position directly below the clamping plate 4, the clamping block 27 just moves to the corresponding position of the recessed opening 30 on the limiting plate 29. At this time, the elastic potential energy accumulated by the restoring spring 28 is released instantaneously, and the clamping block 27 slides along the outer wall of the side connecting rod 26, so as to be completely clamped into the inner wall of the recessed opening 30. Since the shape and size of the recessed opening 30 are matched with the clamping block 27, the clamping block 27 cannot move in the horizontal direction under the limitation of the recessed opening 30, so as to make the whole moving table 5 also unable to move, thereby realizing the accurate locking of the position of the moving table 5, ensuring that the moving table 5 can stably be in the correct position during the stacking process, and ensuring that the paper roll package 13 can be accurately placed on the stacking table 6. When the electric sliding block 14 performs the descending movement to perform the stacking work, since the moving table 5 and the electric sliding block 14 are connected through the pull rope 19, the pull rope 19 has a certain flexibility and length adjustment capability. During the descending process of the electric sliding block 14, the pull rope 19 can be adaptively stretched and contracted according to the relative position change of the electric sliding block 14 and the moving table 5, and will not interfere with the position of the moving table 5 which has been locked.

[0040] As shown in Figures 7 to 8 , the bottom of the limiting plate 29 is slidably connected with the top of the base table 1. The top of the base table 1 is fixedly connected with the telescopic rod 32 in a symmetrical manner. One end of the telescopic rod 32 is fixedly connected with the bottom of the limiting plate 29. One side of the moving table 5 is provided with a reset assembly.

[0041] When working: after completing one stacking work, the telescopic rod 32 is contracted to make the limiting plate 29 move along the surface of the base table 1, so that the clamping block 27 can gradually be separated from the inner wall of the recessed opening 30. Then, the whole moving table 5 can be reset to the original position under the action of the reset assembly. After the moving table 5 is reset, the telescopic rod 32 is elongated to make the limiting plate 29 move and extrude the clamping block 27 to return to the initial state, so that the restoring spring 28 is deformed again to store the elastic potential energy, preparing for the next stacking clamping.

[0042] As shown in Figure 4 and Figure 7As shown, the reset assembly comprises two support frames 36 fixedly connected to the top of the base table 1, a reset spring 35 fixedly connected between one side of the support frame 36 and one side of the connecting plate 25, a plurality of angle clamps 33 fixedly connected to the top of the moving table 5, and a handle 34 fixedly connected between the two sides of the angle clamps 33.

[0043] In operation: when the moving table 5 moves horizontally, the connecting plate 25 will squeeze the reset spring 35 to deform; when the moving table 5 is position-locked by the clamping assembly, the reset spring 35 is always in a deformed state; after the clamping assembly cancels the position locking of the moving table 5, the moving table 5 will move reversely to the original position under the action of the reset spring 35; the angle clamps 33 can prevent the paper rolls 13 from shaking during the movement of the moving table 5; and the handle 34 can facilitate the removal of the stacking table 6 from the top of the moving table 5 to replace a new stacking table 6 for stacking work.

[0044] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the present application.
