[0032] Please see Figures 1 to 5 This invention provides a waste paper palletizing device, mainly used to align and transport multiple paper packages in all directions, forming one layer of a palletized stack after alignment, thereby improving overall conveying and palletizing efficiency. The device includes a workbench 1, a guide plate 3, and a pallet mechanism 2. The workbench 1 is equipped with a rotating assembly 5 for supporting the paper packages, and an adjusting assembly 4 corresponding to the position of the rotating assembly 5.

[0033] Among them, such as Figure 1 As shown, the guide plate 3 is used to convey paper packages to the workbench 1. The guide plate 3 can convey at least two aligned paper packages to the workbench 1 each time. After the paper packages are conveyed to the workbench 1, they fall onto the rotating component 5. When paper packages are conveyed to the workbench 1 again, the next paper package can push the previous paper package to the right. The paper packages can be arranged sequentially on the rotating component 5 in the left and right direction, but there are still gaps between the paper packages at this time and they are not aligned. Then, the adjusting component 4 can be activated to align several paper packages in front, back, left, and right. At this time, the aligned paper packages form one layer in the stack. Then, the adjusting component 4 can be activated again to drive the rotating component 5 to rotate. At this time, the aligned paper packages are blocked by the workbench 1 and cannot move. After the rotating component 5 rotates, the bottom of the paper packages is suspended and loses support, which causes several paper packages to fall onto the tray mechanism 2.

[0034] In the above structure, such as Figure 1 and Figure 2As shown, a corner 101 is formed on one side of the workbench 1 corresponding to the rotating component 5. The corner 101 is composed of the inner rear wall and the inner right wall of the workbench. The corner 101 corresponds vertically to the tray mechanism 2, thereby receiving several falling paper packages. Specifically, the tray mechanism 2 includes a tray and an electric push rod for driving the tray to move up and down. The tray corresponds to the corner 101, and the tray is detachably connected to the output shaft of the electric push rod. After the paper packages are stacked on the tray, the next tray can be directly replaced. The guide plate 3 and the tray mechanism 2 are both existing mature technologies and will not be described in detail here.

[0035] Reference Figures 2 to 4 In this embodiment, preferably, the adjusting assembly 4 includes a cylinder 401 fixedly installed in the worktable 1, a gear 402 rotatably installed in the worktable 1, and a second push plate 404 slidably installed in the worktable 1. The output shaft of the cylinder 401 is fixedly installed with the first push plate 403. Figure 2 As shown, the first push plate 403 and the second push plate 404 cooperate with the corner 101 to achieve rapid alignment of the paper package in the front-back direction and the left-right direction, respectively.

[0036] Among them, such as Figure 3 As shown, both the first push plate 403 and the second push plate 404 are fixedly mounted with toothed plates 405 that are connected to the gear column 402 for transmission. The two toothed plates 405 are vertically staggered and arranged vertically. Through the toothed plates 405, when the first push plate 403 moves backward, the gear column 402 can drive the second push plate 404 to move to the right. Furthermore, the vertical staggered arrangement of the first push plate 403 and the second push plate 404 avoids interference between the first push plate 403 and the second push plate 404 during movement.

[0037] Furthermore, such as Figure 4 As shown, both the surfaces of the first push plate 403 and the second push plate 404 are elastically connected to partitions 406 via a first spring 407. The first spring 407 causes the partitions 406 to tend to move away from the first push plate 403 or the second push plate 404, thereby allowing the partitions 406 to contact the paper package before the first push plate 403 or the second push plate 404. The partitions 406 effectively reduce compression damage to the paper package, ensuring reliable quality of the paper package after stacking, and improving the applicability of the device to stacking paper packages of different sizes. Specifically, one partition 406 is located on the surface of the first push plate 403 away from the cylinder 401, and the other partition 406 is located on the surface of the second push plate 404 away from the toothed post 402.

[0038] Meanwhile, in order to improve the stability of the partition 406 relative to the first push plate 403 or the second push plate 404, as well as the stability of the first spring 407, a telescopic rod (not shown in the figure) can be provided between the partition 406 and the first push plate 403 or the second push plate 404 to assist the horizontal movement of the partition 406.

[0039] Reference Figure 4 and Figure 5 In this embodiment, preferably, the rotating assembly 5 includes a support rod 501 rotatably installed in the workbench 1 and a first slide bar 503 slidably installed in the workbench 1. The bottom of the support rod 501 extends from the bottom of the workbench 1 and is fixedly installed with a base plate 502. The base plate 502 is used to support several paper packages. A gear 504 is fixedly installed on the outer surface of the support rod 501, and a rack 505 corresponding to the position of the gear 504 is fixedly installed on the surface of the first slide bar 503. When the rack 505 contacts the gear 504, it can drive the support rod 501 and the base plate 502 to rotate, and the paper packages will be blocked by the corner 101. Then, the base plate 502 can release the support of the paper packages after rotation.

[0040] The workbench 1 has an internal mounting groove 102 for mounting the support rod 501, gear 504, and first slide bar 503. A partition 406, corresponding to the second push plate 404, extends into the mounting groove 102 to drive the first slide bar 503 to move along the groove 102. It should be noted that the first slide bar 503 is flexible within the mounting groove 102, allowing it to change direction when passing the gear 504.

[0041] In this embodiment, the rack 505 is installed between the gear 504 and the first push plate 403. When the partition 406 corresponding to the second push plate 404 moves to the right from its initial position, it will cause the rack 505 to move away from the gear 504. At this time, the gear 504 will not rotate, thus keeping the bottom plate 502 supporting the paper package. When the partition 406 corresponding to the second push plate 404 moves to the left from its initial position, it can cause the rack 505 to contact the gear 504, thereby causing the gear 504 to rotate 90 degrees counterclockwise, releasing the support of several paper packages, so that the aligned paper packages fall onto the tray mechanism 2 below.

[0042] In use, the guide plate 3 first conveys several paper packages from one layer of the stack to the base plate 502 in a row. Then, the cylinder 401 is activated to drive the first push plate 403 to move backward from its initial position. The first push plate 403 drives the second push plate 404 to move to the right from its initial position through the toothed plate 405 and the toothed column 402. With the help of the corner 101 and the partition 406, several paper packages can be aligned in the front-back and left-right directions. After alignment, several paper packages are located above the base plate 502 and are in contact with the corner 101. During this process, the partition 406 corresponding to the second push plate 404 can drive the first slide bar 503 to move, so that the rack 505 moves away from the gear 504.

[0043] Next, cylinder 401 drives the first push plate 403 to reset and move forward from its initial position. The first push plate 403, through toothed plate 405 and toothed column 402, drives the second push plate 404 to reset and move to the left from its initial position. At this time, the partition 406 corresponding to the second push plate 404 can drive the first slide bar 503 to move in the opposite direction, so that the rack 505 contacts the gear 504 and drives the support rod 501 to rotate 90 degrees counterclockwise. The support rod 501 drives the base plate 502 to move synchronously to release the support for several paper packages. Several paper packages are blocked by corner 101 and will not move, and can finally fall onto the pallet mechanism 2. Finally, the pallet mechanism 2 descends one layer and repeats this cycle until the corresponding stack is formed.

[0044] In summary, through the cooperation of the first push plate 403, the second push plate 404, and the partition plate 406, several paper packages can be quickly aligned in the front-back and left-right directions, forming one layer of a stack and being tightly fitted. Then, the paper packages in one layer are synchronously transported to the pallet mechanism 2 to complete the stacking. There is no need to repeatedly transport individual paper packages for stacking, which can effectively improve the overall conveying efficiency and stacking efficiency. Furthermore, when the aligned paper packages are transported, they fall directly without any gaps in front, behind, left, or right, which can further improve the overall stacking effect.

[0045] Through the cooperation of structures such as corner 101, base plate 502 and support rod 501, corner 101 is used on the one hand to cooperate with the first push plate 403 and the second push plate 404 to align several paper packages, and on the other hand to limit the alignment of several paper packages after the base plate 502 rotates, which can ensure the stable delivery of several paper packages to the pallet mechanism 2 after alignment; and corner 101 itself utilizes the structure of the workbench 1, which can further reduce the operating cost without the need for additional parts.

[0046] Through the cooperation of the partition 406 and the first spring 407, the partition 406 has room to move relative to both the first push plate 403 and the second push plate 404, which can effectively reduce the squeezing damage to the paper package. This device is applicable to the stacking of paper packages of different sizes and can also meet the stacking requirements of different stack shapes. The overall structure is simple and the operating cost is lower, making it more practical and applicable. Example 2:

[0047] Please see Figures 1 to 7 Based on Embodiment 1, considering that the paper package is conveyed to the workbench 1 from left to right, while the base plate 502 rotates counterclockwise, and the gear 504 is separated from the rack 505 in the initial state, the gear 504 may deflect when subjected to force; therefore, when the paper packages are conveyed to the workbench 1 in a row and fall onto the base plate 502, it may cause the base plate 502 to rotate and deviate, thereby affecting the overall paper package conveying and alignment stacking.

[0048] Therefore, the partition 406 and the rack 505 are improved: the rack 505 is set between the support rod 501 and the second push plate 404, and there is a gap between the rack 505 and the gear 504 in the initial state; when the partition 406 corresponding to the second push plate 404 drives the first slide bar 503 to move, that is, drives the rack 505 to approach the gear 504. When the partition 406 corresponding to the second push plate 404 contacts the paper package, the rack 505 can contact the gear 504 and drive the support rod 501 to rotate.

[0049] Through the above design, such as Figure 6 As shown, the base plate 502 is configured to rotate only clockwise in its initial state, and not counterclockwise. In this configuration, the conveying of the paper package to the base plate 502 will not cause it to rotate or shift, ensuring stable subsequent conveying and alignment of the paper package for stacking. Simultaneously, the partition 406 moves further closer to the paper package along the direction of movement, allowing the paper package to fall onto the pallet mechanism 2 for stacking while being limited by the corner 101 and the two partitions 406, further improving the stacking efficiency.

[0050] Furthermore, such as Figure 6 As shown, several rollers 6 can be rotatably installed on the surface of the partition 406 near the corner 101. At this time, the contact between the partition 406 and the paper package is changed to the contact between the rollers 6 and the paper package. After several paper packages are aligned, the paper packages can still be easily moved in the up and down direction.

[0051] In use, the first push plate 403, the second push plate 404, the bottom plate 502 and the partition plate 406 can quickly align several paper packages in the front-back and left-right directions. Then, the aligned and attached paper packages are transported to the pallet mechanism 2 at one time. The working process and effect of this part are the same as in the first embodiment, and will not be repeated here. The difference is as follows: when the first push plate 403 and the second push plate 404 move, after aligning several paper packages in the front-back and left-right directions through the partition plate 406 and the corner 101, the roller 6 directly contacts the side wall of the paper package. At this time, the first push plate 403 and the second push plate 404 continue to move closer to the paper package. The partition plate 406 corresponding to the second push plate 404 drives the rack 505 to contact the gear 504 through the first slide bar 503. The support rod 501 drives the base plate 502 to rotate 90 degrees clockwise to release the support for the paper package. During this process, the roller 6 always maintains contact with the paper package, and the roller 6 allows the paper package to fall easily onto the tray mechanism 2.

[0052] Compared to Embodiment 1, by coordinating the structures such as partition 406, roller 6, first slide bar 503, and rack 505, the rotation direction of the base plate 502 is adjusted to be offset from the feeding direction of the paper package onto the base plate 502. This avoids rotational offset of the base plate 502 during paper package feeding, thereby ensuring stable overall conveying of the paper package and subsequent alignment and stacking, without affecting the rapid alignment of several paper packages by the partition 406 and roller 6.

[0053] Meanwhile, the paper packages can be conveyed to the pallet mechanism 2 while the rollers 6 are always in contact, thus ensuring that several paper packages are aligned and tightly packed, which can further improve the conveying and stacking effect to the pallet mechanism 2. The rollers 6 ensure the alignment of the paper packages without affecting the conveying of the paper packages to the pallet mechanism 2, resulting in better overall performance. Example 3:

[0054] Please see Figures 1 to 10 Based on Embodiment 2, considering that the spacing of the rack 505 based on the gear 504 is relatively fixed, it is impossible to control the rotation time of the base plate 502 to adapt it to paper packages of different sizes. This may also affect the conveying of paper packages on the base plate 502 to the pallet mechanism 2 and the alignment of paper packages on the base plate 502.

[0055] Therefore, the partition 406 and the first slide bar 503 are improved: the surface of the first slide bar 503 near the partition 406 is provided with a number of linearly distributed slots 506, and the surface of the partition 406 corresponding to the second push plate 404 is provided with a moving component 7 corresponding to the position of the slots 506. The moving component 7 is located on the surface of the partition 406 near the corner 101, and the moving component 7 protrudes from the partition 406 relative to the roller 6, so that when the partition 406 moves towards the paper package, the moving component 7 contacts the paper package before the roller 6. At this time, the moving component 7 can be engaged and inserted into one of the slots 506, and then the partition 406 and the first slide bar 503 move synchronously through the slot 506 and the moving component 7.

[0056] Reference Figures 8 to 10 In this embodiment, preferably, the moving component 7 includes a second slide bar 701 and a card holder 702 that slide in cooperation with the corresponding partition 406. The card holder 702 is fixedly connected to the second slide bar 701, and a second spring 703 is fixedly installed between the card holder 702 and the partition 406. The second spring 703 causes the card holder 702 to have a tendency to retract into the partition 406, and the second spring 703 causes the card holder 702 to be in a state of retracting into the partition 406 in the initial state.

[0057] The second slide bar 701 is made of the same material as the first slide bar 503. It is L-shaped and can move in different directions within the partition 406. The end of the second slide bar 701 away from the card holder 702 protrudes relative to the partition 406. The second slide bar 701 also protrudes relative to the roller 6 based on the partition 406. That is, when the partition 406 moves closer to the paper package, the second slide bar 701 can contact the paper package before the roller 6. After pushing the paper package to align in the left and right direction, the second slide bar 701 can retract into the partition 406, thereby driving the card holder 702 to extend out from the partition 406 and engage with one of the card slots 506.

[0058] Furthermore, such as Figure 10 As shown, an arc edge 508 is provided at the junction between two adjacent slots 506 to quickly guide the card holder 702 to engage and insert into one of the slots 506. After the card holder 702 extends out of the partition 406, it can quickly drive the first slide bar 503 and the rack 505 to move, thereby making contact with the gear 504. When the card holder 702 does not extend out of the partition 406, the first slide bar 503 and the rack 505 are in a stationary state.

[0059] In this embodiment, as Figure 10 As shown, a third spring 507 can also be fixedly installed between the end of the first slide bar 503 away from the rack 505 and the mounting groove 102. The third spring 507 is used to make the first slide bar 503 quickly reset, thereby making the base plate 502 quickly reset, which facilitates the support of the paper package conveyed by the subsequent guide plate 3.

[0060] In use, the first push plate 403, the second push plate 404, and the partition 406 can quickly align several paper packages in the front-back and left-right directions. The aligned and attached paper packages are then transported to the pallet mechanism 2 at once. The partition 406, the roller 6, and the rack 505 can adjust the rotation direction of the base plate 502 to be offset from the feeding direction of the paper packages onto the base plate 502, ensuring the stable transport of the paper packages and subsequent alignment and stacking. The working process and effect of this part are the same as in Embodiment 2, and will not be repeated here. The difference is that when the partition 406 corresponding to the second push plate 404 moves towards the paper package, the second slide bar 701 contacts the paper package before the roller 6. At this time, several paper packages can be pushed to align in the left and right direction. At this time, the right side of the paper package is blocked by the corner 101 and cannot move further. The second slide bar 701 begins to retract into the partition 406 and drives the card holder 702 to extend out from the partition 406. The card holder 702 can be engaged and inserted into one of the card slots 506, thereby causing the card holder 702, the partition 406, the first slide bar 503 and the rack 505 to move synchronously. At this time, the rack 505 can contact the gear 504 and drive the support rod 501 and the base plate 502 to rotate 90 degrees clockwise, so that the aligned paper package falls onto the tray mechanism 2.

[0061] Compared to Embodiment 2, through the cooperation of structures such as partition 406, second slide bar 701, card seat 702, and card slot 506, after several paper packages are aligned in the left and right directions and can no longer move, partition 406 can drive the first slide bar 503 and rack 505 to move synchronously, and then the base plate 502 can rotate to transport the aligned paper packages to the pallet mechanism 2; the rotation time of the base plate 502 can be controlled after several paper packages are aligned in the front, back, left, and right directions, thereby ensuring applicability to paper package stacking of different sizes and different stacking shapes, further ensuring overall applicability. Example 4:

[0062] Please see Figures 1 to 10 This invention provides a waste paper palletizing method. This embodiment uses any one of the waste paper palletizing devices in Embodiments 1 to 3, and therefore also has corresponding beneficial effects.

[0063] Specifically, firstly, the guide plate 3 conveys paper packages to the workbench 1 in sequence and they fall onto the rotating component 5. The paper packages that fall onto the rotating component 5 are arranged in sequence from left to right. Then, the adjustment component 4 is activated to align the paper packages in the front-back and left-right directions. Then, the adjustment component 4 drives the rotating component 5 to rotate 90 degrees to release the support of the paper packages, so that the aligned paper packages fall onto the tray mechanism 2.
