DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application will be further described below in combination with specific embodiments.

[0032] 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, 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.

[0033] 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 in transverse direction;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, moving table 5 and stacking table 6 move forward by pull-in assembly, 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 drives stagnation table 3 to rotate, so as to change its position state and avoid affecting the movement path of clamping plate 4 when it descends to place paper roll package 13 above stacking table 6;

[0034] When moving table 5 and stacking table 6 move below clamped paper roll package 13, the current position of moving table 5 and stacking table 6 is locked by clamping assembly, then clamping plate 4 is lowered by lifting assembly, so that paper roll package 13 is stably placed on the upper surface of stacking table 6, after paper roll package 13 is placed, clamping plate 4 moves away from each other 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, and as the stacking height of the surface of stacking table 6 gradually increases, the distance of clamping plate 4 each time needs to be adjusted adaptively;

[0035] After each layer of stacking work is completed, the locking of the mobile platform 5 and the stacking platform 6 position by the clamping assembly is cancelled, the mobile platform 5 and the stacking platform 6 move reversely to restore the original position, when resetting, the transmission assembly makes the stationary platform 3 restore to the original position state, re-receive the next group of paper roll package 13 transported by the conveying mechanism 2, and the cycle continues until the stacking platform 6 is removed from above the mobile platform 5 after stacking to the appropriate height, and a new stacking platform 6 is replaced to continue the stacking work;

[0036] Through the above embodiment, during the lifting of the paper roll package 13 by the clamping plate 4, the pulling assembly drives the mobile platform 5 and the stacking platform 6 to move forward, when the clamping plate 4 and the paper roll package 13 are lifted to the highest position, the mobile platform 5 drives the stacking platform 6 to move just below the plurality of paper roll packages 13, providing position guarantee for the accurate placement of the paper roll package 13 on the stacking platform 6. After clamping the paper roll package 13, it does not need to be turned and placed on the stacking platform 6, solving the situation of sliding due to centrifugal force in the prior art, and the stacking process of the paper roll package 13 can be realized by simple lifting movement after clamping the paper roll package 13; through the transmission assembly, when the mobile platform 5 moves forward, the transmission assembly drives the stationary platform 3 to rotate, changing the position state of the stationary platform 3, avoiding the influence of the stationary platform 3 in the original position on the movement path of the clamping plate 4 to place the paper roll package 13 above the stacking platform 6, ensuring that the paper roll package 13 can be placed smoothly from the clamping plate 4 to the stacking platform 6, and ensuring the smooth progress of the stacking process; through the clamping assembly, when the mobile platform 5 and the stacking platform 6 move below the clamped paper roll package 13, the clamping assembly locks the current position of the mobile platform 5 and the stacking platform 6, ensuring that the paper roll package 13 does not slip or stack irregularly during the process of the lifting assembly driving the clamping plate 4 to place the paper roll package 13 on the stacking platform 6, ensuring that the paper roll package 13 can be accurately and stably placed on the stacking platform 6, and making the stacked paper roll package 13 more stable.

[0037] 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 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, the two ends of the hydraulic cylinder 9 are respectively fixedly connected with one side of the two inner sliding blocks 8, and the bottom of the inner sliding block 8 is respectively fixedly connected with the top of the clamping plate 4.

[0038] When working: in the initial state, the two clamping plates 4 are respectively located on both sides of the stagnation table 3 and do not contact the side edges of the roll paper package 13, which will not affect the horizontal stacking of the roll paper package 13 transported to the surface of the stagnation table 3 by the conveying mechanism 2; when a group of roll paper packages 13 need to be clamped, the hydraulic cylinder 9 is started to make it shrink, at this time, the two inner sliding blocks 8 will relatively move close along the inner wall of the fixed inner groove seat 7, thereby driving the two clamping plates 4 to move close to each other, clamping and wrapping the side edges of the plurality of roll paper packages 13; in this process, the clamping force of the clamping plate 4 needs to be reasonably controlled to prevent the roll paper package 13 from deforming and affecting the stability of subsequent stacking.

[0039] As shown in Figures 3 to 5 , the upper side of the fixed inner groove seat 7 is fixedly connected with a fixed plate 10, the upper side 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 with the inner wall of the top plate frame 11.

[0040] When working: when the roll paper package 13 clamped on the clamping plate 4 needs to be lifted away from the surface of the stagnation table 3, the lifting assembly is started to make the top plate frame 11 rise, thereby driving the clamping plate 4 and the roll paper package 13 to rise together; when the roll paper package 13 needs to be placed on the stacking table 6, the lifting assembly controls the top plate frame 11 to descend, realizing the accurate placement of the roll paper package 13; at the same time, through the setting of the motor 12, the rotating function of the clamping plate 4 can be realized, so that the roll paper packages 13 can be placed staggered in each layer of stacking, that is, the placement position of the roll paper package 13 in the upper layer is formed with a certain displacement with the lower layer. This staggered stacking mode increases the friction and mutual support force between the roll paper packages 13, effectively improving the stability and firmness of the stacking.

[0041] As shown in Figures 5 to 6 , the lifting assembly comprises two electric guide rails 15, which are symmetrically fixedly connected to the upper side 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.

[0042] When the clamping plate 4 and the paper roll package 13 clamped by the clamping plate 4 need to be lifted, the electric guide rail 15 is started, and the electric guide rail 15 usually has corresponding driving devices (such as a motor, a lead screw, etc., which are not shown in detail in the figure, but are common structures of the electric guide rail) inside, under the action of the driving force, the electric sliding block 14 moves linearly upward along the inner wall of the electric guide rail 15. Since the inner wall of the electric sliding block 14 is in close sliding connection 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 is ensured that the electric sliding block 14 can stably and accurately rise along the predetermined track without deviation or shaking.

[0043] As shown in Figures 5 to 6 , the pulling-in assembly includes two pull ropes 19, and the two sides of the moving table 5 are fixedly connected with the bottom of the electric sliding block 14. Limit rods 17 are arranged on the bottom of the electric sliding block 14 and the two sides of the moving table 5, and the outer walls of the limit rods 17 are rotatably connected with pull force blocks 18. The two ends of the pull rope 19 are fixedly connected with the outer walls of the two pull force blocks 18 respectively.

[0044] When working: in the initial state, the clamping plate 4 is located at the two 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 at one side 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 roll packages 13 upward. In the process of upward movement of the electric sliding block 14, since one end of the pull rope 19 is fixedly connected with the pull force block 18 corresponding to the limit rod 17 on the bottom of the electric sliding block 14, and the other end is fixedly connected with the pull force block 18 corresponding to the limit rod 17 on 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 force block 18 will adaptively rotate on the outer wall of the limit rod 17, so as to ensure that the pulling force of the pull rope 19 can be stably and smoothly transmitted, so that the moving table 5 can move in the expected direction.

[0045] 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.

[0046] 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 defined by the pulley groove 21, thereby ensuring that the moving table 5 can accurately move along the predetermined horizontal path.

[0047] As shown in Figures 3 to 4As shown, the transmission assembly comprises 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 two ends of the bearing seat 22 are fixedly connected with a gear 23, the two 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 the gear teeth of the rack plate 24 is one fourth of the number of the gear teeth of the gear 23.

[0048] When working: in the initial state, the stationary table 3 maintains a horizontal state, because the shaft rod of the bearing seat 22 needs to rotate with a large force, this feature makes even if it bears a plurality of paper roll packages 13 above, in view of the overall light weight of the paper roll package 13, the stationary table 3 still can stably maintain the horizontal state, providing a stable platform for subsequent paper roll package 13 processing operation; when the moving table 5 moves along the horizontal direction, with the travel of the moving table 5, the rack plate 24 on the top of the connecting plate 25 on both sides also synchronously moves, because the gear teeth of the gear 23 can be intermeshed with the gear teeth of the rack plate 24, when the rack plate 24 moves, its gear teeth will sequentially contact the gear teeth of the gear 23 and generate a mutual force, thereby driving the gear 23 to start rotating, the one end of the stationary table 3 driven by the gear 23 will be hinged downward with the shaft rod of the bearing seat 22 as the center, and because the number of the gear teeth of the rack plate 24 is one fourth of the number of the gear teeth of the gear 23, the stationary table 3 will rotate 90 degrees, just overlapping with 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 package 13 and affects the surface stacking layer of the stacking table 6, when the stacking layer is high, due to the influence of the stationary table 3, it cannot be moved directly below the clamping plate 4.

[0049] As shown, Figures 7 to 8 The clamping assembly comprises two side connecting rods 26, the side connecting rods 26 are fixedly connected to the two sides of the moving table 5, the outer walls of the side connecting rods 26 are slidingly connected with clamping blocks 27, the one side of the clamping block 27 is fixedly connected with a restoring spring 28 between the side surface of the moving table 5, the one side of the clamping block 27 abuts against a limiting plate 29, one end of the limiting plate 29 is provided with a recessed port 30, the recessed port 30 and the clamping block 27 are mutually adapted in shape and size, the inner walls of the limiting plate 29 and the recessed port 30 are provided with side sliding grooves 31, the outer walls of the side connecting rods 26 are slidingly connected with the inner walls of the side sliding grooves 31 and are mutually adapted.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application.
