Description

Technical Field

[0001] The present invention relates to the technical field of carton stacking, and in particular to an intelligent stacking device and method for carton production. Background Art

[0002] Cartons are usually used as wrapping materials for goods or as outer protective materials for articles. As an indispensable part of modern logistics, they bear the important responsibilities of containing, protecting products and making them beautiful. After a series of production processes, carton boards often need to be stacked neatly for easy handling and storage.

[0003] For carton blocks formed by bundling multiple single cartons together, the existing carton stacking method is mostly to stack them layer by layer through mechanical equipment. The advantages of mechanical equipment are low cost and simple operation. However, when stacking in this way, the carton blocks are not stable. They can be moved on the pallet, but their stability will decrease as the height of the carton stacking increases during the movement. Therefore, manual methods are usually used to rotate and stagger the cartons so that the placement angles of the cartons on the same layer are 90 degrees to each other, and the adjacent two layers are interlocked and crossed to increase their stability during placement and transportation. Figure 1 As shown, although this method is stable, it needs to be completed through a single manual operation, which is costly and inefficient.

[0047] The control group also includes a reversing group, which is used to intermittently control the opening of the first cylinder 12 and the second cylinder 13 according to the movement degree of the spur rack 23.

[0048] As a further solution of the present invention, the reversing group includes a plurality of first sensors 24, a plurality of second sensors 25 and a sensing block 26. The first sensors 24 and the second sensors 25 are intermittently distributed. The sensing block 26 is fixedly connected to the tail end of one of the spur racks 23.

[0051] like Figure 2 , Figure 3 , Figure 5-Figure 12 As shown:

[0052] The first layer of stacking work:

[0053] The conveyor belt 3 is supported by the conveyor frame 2, and the conveyor belt 3 conveys the carton to the support plate 7. Before conveying, the induction block 26 is on the side of the first sensor 24 at the rear. At this time, the first sensor 24 will control the first cylinder 12 to be in a working state. In the working state, the first cylinder 12 can push each carton conveyed forward on the conveyor belt 3 from the middle position of the conveyor belt 3 to the left side (i.e., the direction of the second cylinder 13) to the limit position, and then continue to convey forward;

[0054] When the carton is conveyed to the support plate 7, the side wall of the carton will contact the side wall of the limiting block 9 inside the through slot 8. At this time, the limiting block 9 will block the carton so that the carton can stay in a fixed position, and the top of the tray 4 is flush with the top of the through slot 8, so the carton will stay directly on the tray 4 at this time, and then the intelligent control component will control the first motor 27 to rotate (the intelligent control component can be any one of the existing technologies, and its purpose is to control the first motor 27 to rotate after each carton is conveyed to the tray 4). The first motor 27 will drive the friction wheel 28 to rotate. The friction wheel 28 is in contact with the side wall of the support plate 7, and then it will drive the support plate 7 to rotate ninety degrees clockwise. When the support plate 7 rotates, it can be driven by the insertion rod 11 The movable receiving plate 6 rotates ninety degrees together with the pallet 4, and the limiting block 9 will also rotate with the carton while maintaining contact with the carton. The receiving plate 6 will rotate inside the clamp 5 at this time (the top and bottom of the receiving plate 6 are provided with circular grooves, and the upper and lower ends of the clamp 5 are both located in the grooves, thereby supporting the receiving plate 6, and the supporting plate 7 also slides with the crossbeam 10 in the same way). At this time, the first carton already on the pallet 4 will rotate ninety degrees, so that the second carton can be transported to the other side of the pallet 4, and then the first motor 27 rotates again, causing the pallet 4 to rotate ninety degrees again, until the fourth carton is transported to the pallet 4. At this time, the pallet 4 will stay in the initial position after four rotations, and the cartons on the pallet 4 will be as shown. Figure 1 The state shown in a in the figure shows that the stacking of one layer of cartons is completed.

[0055] Because the arc-shaped rack rod 15 is located on one side of the first gear 16, when the support plate 7 rotates clockwise for the first, second and third time, the first gear 16 will not mesh with the arc-shaped rack rod 15. When the fourth carton is delivered to the pallet 4, the pallet 4 completes one layer of stacking, and the support plate 7, the receiving plate 6 and the pallet 4 will experience the fourth rotation. After the arc-shaped rack rod 15 rotates for the fourth time, it will be reset to the position as shown in FIG. Figure 5 The initial state is reset to one side of the first gear 16, but the arc-shaped rack rod 15 contacts the first gear 16 during the fourth rotation and drives the first gear 16 to rotate, and then the subsequent tray 4 is lowered by one layer, thereby preparing for the stacking of the second layer.

[0056] Preparation for the second layer of stacking:

[0057] Before the fourth rotation of the arc-shaped rack rod 15 is completed, the first gear 16 will mesh with the arc-shaped rack rod 15. At this time, the first gear 16 will drive the two second gears 17 to rotate through the two chains 18. When the two second gears 17 rotate, they will respectively drive the two spur racks 23 to slide forward a certain distance along the support frame 1. The spur rack 23 will move forward and press down the positioning piece 21 at the rear during the process of moving forward. After being pressed down by the spur rack 23, the positioning piece 21 will slide down along the support frame 1 and compress the first spring 22, thereby making the positioning piece 21 slide. When the block 20 gives way, the slider 20 will be pushed forward to the position in contact with the front positioning piece 21 through the clamp 5 and the support rod 19 under the weight of the pallet 4. At this time, the clamp 5, the pallet 4 and the receiving plate 6 will all drop a certain distance. At this time, the receiving plate 6 will drop along the insertion rod 11. At this time, the cartons that have been stacked on one layer will drop to a position where the top is flush with the top of the through slot 8, thereby facilitating the stacking of the second layer. When the arc-shaped rack rod 15 passes over the first gear 16 and resets, the pallet 4 has dropped one layer, thereby preparing for the subsequent stacking of the second layer.

[0058] Then the stacking work of the first layer can be carried out to stack the second layer, but when stacking the second layer, the spur rack 23 moves forward a certain distance, so at this time the induction block 26 will move from one side of the first sensor 24 to the side of the second sensor 25, and at this time the first sensor 24 and the first cylinder 12 will stop working, the second sensor 25 will control the second cylinder 13 to work, and the second cylinder 13 and the push plate 14 will push all the cartons transported forward by the conveyor belt 3 in the direction of the first cylinder 12, so that the cartons transported by the conveyor belt 3 are close to the left side when stacking the first layer, and close to the right side when stacking the second layer, so when the second layer is stacked, the stacking looks like this: Figure 1 The state at point b in the middle makes the cartons on the first and second layers cross-engaged, thereby improving the stability of subsequent transportation and stacking;

[0059] After the second layer of stacking is completed, the clamp 5, the tray 4 and the receiving plate 6 will be lowered one layer again, and the third layer of stacking can be carried out at this time (as shown in Figure c). When the third layer of stacking is carried out, the spur rack 23 will move forward a certain distance again, so that the induction block 26 will move forward again and be on the side of the first sensor 24 again, so that when the third layer of stacking is carried out, the carton will be closer to the left side again when it is transported forward, so that the stacking directions of the cartons of the adjacent two layers are opposite, ensuring that the head and tail directions of the adjacent two layers can be in a cross-bite state;

[0060] Then you can start the fourth layer, the fifth layer, etc. until the stacking is completed;

[0061] After stacking is completed, the receiving plate 6 will drop to the ground. At this time, the pallet 4 and the cartons stacked above need to be removed. When removing, the third cylinder 29 is started first. The third cylinder 29 will extend and lift the crossbeam 10. The crossbeam 10 will drive the limiting block 9 and the supporting plate 7 to rise to a height higher than the carton. Then the pallet 4 is directly pushed out from above the receiving plate 6 and a new pallet 4 is placed. Then the third cylinder 29 is shortened and reset, and then the second motor 37 is started. The second motor 37 will drive the third gear 38 to rotate, and then the meshing of the third gear 38 and the spur rack 23 drives the spur rack 23 to reset. At this time, the support rod 19 will push the receiving plate 6 and the pallet 4 to the highest point, and then the subsequent stacking work is carried out.

[0062] In this way, after the cartons are transported to the pallet 4, the pallet 4 is rotated multiple times so that after the first layer of stacking is completed, it will drop a certain distance to prepare for the second layer of stacking. Each drop of the pallet 4 can change the left or right side of the conveyor belt 3 when transporting the cartons, and form a cycle to complete multi-layer stacking, ensuring that the heads and tails of the cartons on the adjacent sides are in a cross-engaged state, and the number of processes is small and integrated, which reduces the production cost.

[0063] As a further solution of the present invention, an adjustment group is provided below the crossbeam 10, and the adjustment is used to adjust the placement position of the carton on the pallet 4;

[0064] The adjustment group includes four adjustment rods 30, and the four adjustment rods 30 are all rotatably connected to the limiting block 9. The rotating shafts of the adjustment rods 30 are sleeved with torsion springs 31. A contact block 32 is provided on one side of the rotation direction of the adjustment rods 30. The contact blocks 32 are fixedly connected to the cross beam 10. When the adjustment rods 30 rotate, they can be pressed down by the contact blocks 32.

[0065] like Figure 3 and Figure 4 As shown:

[0066] The bottom ends of the four adjusting rods 30 are higher than a layer of cartons. After each carton is conveyed to the pallet 4, as the pallet 4 rotates, the limiting block 9 will drive the adjusting rod 30 to rotate and during the initial rotation, the top end of the adjusting rod 30 will contact the contact block 32 and press the adjusting rod 30 downward, so that the bottom end of the adjusting rod 30 can move toward the carton from one side and squeeze the carton toward the middle, and the carton is limited by the limiting block 9 in the middle position, so that the cartons can fit together head to tail, ensuring the neatness and consistency of the stacking.

[0067] As a further solution of the present invention, a groove matching the limiting block 9 is provided at the top of the tray 4, a plurality of L-shaped rods 33 are slidably connected to the receiving plate 6, a second spring 34 is fixedly connected between the L-shaped rod 33 and the top of the receiving plate 6, and a slot 35 is provided at the position corresponding to the navigation of the tray 4 and the L-shaped rod 33, and the L-shaped rod 33 is slidably connected to the slot 35.

[0068] like Figure 7 and Figure 8 As shown:

[0069] A groove matching the limiting block 9 is provided at the top of the tray 4. When the tray 4 is at the top, the groove will be inserted into the bottom of the limiting block 9, which facilitates the matching between the two and enables the limiting block 9 and the tray 4 to rotate synchronously when stacking on one layer. When the tray 4 is lowered, it will be separated from the limiting block 9, ensuring the stability of the bottom stacking, thereby improving the overall performance;

[0070] When the tray 4 descends to contact the ground, the L-shaped rod 33 will be lifted up and slide up along the receiving plate 6. At this time, the second spring 34 will be stretched, and then the top end of the L-shaped rod 33 will be pushed out from the inside of the slot 35, thereby facilitating the pushing out of the tray 4. When the tray 4 rises, the L-shaped rod 33 will engage the slot 35, thereby improving the stability on the receiving plate 6.

[0071] As a further solution of the present invention, a plurality of rollers 36 are rotatably connected to the end surface of the conveying frame 2 and the inner center of the support plate 7 near the four corners.

[0072] like Figure 5 and Fig.12 As shown:

[0073] The rollers 36 on the support plate 7 and the rollers 36 on the conveyor frame 2 can reduce the friction when the carton leaves the conveyor belt 3.

[0074] An intelligent stacking method for carton production, the method comprising the following steps;

[0075] Step 1: Each time the conveyor belt 3 conveys the cartons to the pallet 4, the driving group drives the support plate 7 to rotate 90 degrees synchronously with the pallet 4, so that the cartons can be stacked on the pallet 4;

[0076] Step 2: When the limiting block 9 rotates, the contact block 32 will contact the adjusting rod 30 and press the contact block 32 downward, so that the adjusting rod 30 can squeeze and adjust the carton from four directions;

[0077] Step 3: After the four cartons are transported to the tray 4, the first gear 16 meshes with the arc-shaped rack rod 15, and then the control group causes the clamp 5, the tray 4 and the receiving plate 6 to drop a certain distance to perform the second layer of stacking;

[0078] Step 4: After each layer of stacking is completed, the reversing group can change the left and right directions of the cartons on the conveyor belt 3 so that the cartons on the adjacent sides are in a cross-engaging state;
