Description

Technical Field

[0001] This invention relates to the field of cargo transportation technology, specifically to a stacking alignment device and a stacking method. Background Technology

[0002] In the processing, packaging, warehousing, and transportation of sheet materials, it is usually necessary to stack the sheets according to a set quantity and position, and then use a palletizer to complete the subsequent handling, stacking, or transfer. Therefore, the stacking equipment can be understood as the sheet material sorting, alignment, and stacking unit in the front end or supporting station of the palletizer. The palletizer is used to grab, transport, and place the stacked sheet material. Because sheet materials usually have characteristics such as large area, long edges, and significant influence from conveying inertia, problems such as front-end overshooting, rear-side offset, uneven left and right sides, and inter-layer misalignment are prone to occur when entering the stacking station. If only manual adjustment or ordinary conveying mechanism is used for positioning, it will not only increase the operation time, but also easily cause problems such as sheet material corner collisions, inconsistent stacking benchmarks, and unstable subsequent palletizing and grabbing.

[0003] Publication number CN109987419B discloses a sheet metal stacking device and sheet metal palletizing equipment. The solution involves setting up a sheet metal stacking device, an industrial robot, a gripping mechanism, and a sheet metal palletizing auxiliary mechanism. The gripping mechanism is mounted on the end effector of the industrial robot. Through the cooperation of a stacking frame, a conveying mechanism, a centering mechanism, and a lifting mechanism, the sheet metal is stacked above the conveying mechanism. The technical objective of this solution is to utilize the industrial robot and gripping mechanism to complete sheet metal handling, and the conveying mechanism and lifting mechanism to complete the entry, lifting, and stacking of sheet metal, thereby reducing space occupation and improving the adaptability of the sheet metal palletizing equipment to different sheet metal handling needs.

[0004] However, the aforementioned comparative documents primarily rely on the coordination between industrial robots, gripping mechanisms, conveying mechanisms, centering mechanisms, and lifting mechanisms to complete the stacking and palletizing of sheet metal. They focus more on overall handling and spatial arrangement, and do not establish independent front-side alignment links for the processes of front-end contact, buffering, vertical adaptation, and reset limiting when the sheet metal enters the stacking station. When the sheet metal enters the stacking area along the conveying direction, if the front end of the sheet metal has inertial forward thrust, edge skew, or thickness differences, relying solely on the conveying and centering structures is insufficient to promptly constrain the front end of the sheet metal to a uniform reference position. This can easily lead to a lack of front-side positioning foundation for subsequent side pushing, rear pushing, and lifting stacking.

[0005] Therefore, in order to address the shortcomings of the existing system, research and improvement were carried out, and a stacking alignment device, stacking equipment and stacking method were proposed. Summary of the Invention

[0010] Furthermore, the third alignment mechanism also includes a side push frame, a drive folding plate, a toggle piece, a screw sleeve, a fourth spring, a first sliding shaft, a first spring, and a sliding plate. The first sliding shaft is provided on the inner side of the rectangular notch, and a sliding plate is sleeved on the outer side of the first sliding shaft.

A fourth spring is provided on the inner side of the toggle piece. A screw sleeve is provided on the inner side of the fourth spring. A protruding rod is provided at one end of the back of the toggle piece, and the protruding rod is fixedly connected to one end of the vertical push piece.

[0011] Furthermore, the top of the erecting frame is provided with a top frame, and a rotating rod is provided inside the top frame. A second motor is provided on one side of the rotating rod, and a vertically oriented transmission belt is provided on the other side of the second motor. The bottom of the erecting frame is provided with a bottom frame, and a first electric control drive box is provided on both sides of the bottom frame.

[0012] Furthermore, the horizontally oriented conveyor belt is located inside the upper frame, and the conveying direction of the horizontally oriented conveyor belt is consistent with the direction in which the stacked parts enter the gantry platform. The horizontally oriented conveyor belt is used to transport the stacked parts to the corresponding positions of the first or second placement platform. A limit block is provided on one side of the upper frame, and the limit block is used to limit the stopping position of the stacked parts after they enter.

[0013] Furthermore, the erecting frame is set along the height direction of the gantry platform, the top frame is fixed to the top of the erecting frame, the second motor drives the vertical transmission belt to run through the rotating rod, the vertical transmission belt is used to drive the stacked plates or supporting components to rise and fall in the vertical direction, the bottom frame is used to support the bottom of the erecting frame, and the first electric control drive box is used to control the start and stop of the first motor, the second motor, the horizontal transmission belt, the vertical transmission belt and the lateral transmission belt.

[0014] Furthermore, the lower pressure frame is located directly above the first placement platform, and the lateral direction conveyor belt is set at both ends of the inner side of the lower pressure frame. The lower pressure frame is used to limit the upper part of the plate to be stacked, and the lateral direction conveyor belt is used to cooperate with the movement of the plate to be stacked on both sides, so that the plate to be stacked is kept in the stacking station during the process of front limit, rear push and lateral alignment.

[0015] The stacking method includes the following steps: S1: The plate to be stacked is fed into one side of the gantry platform. The first motor drives the horizontal transmission belt to run, so that the plate to be stacked enters the stacking station along the length of the gantry platform. S2: After the stacked plate is moved to the corresponding position of the limit block, it stops moving forward. The first or second placement platform receives the stacked plate and the lower pressure frame limits the upper part of the stacked plate. S3: The side groove plate drives the side support plate, top frame plate and auxiliary plate to move through the adapter sliding shaft, so that the first alignment mechanism, the second alignment mechanism and the third alignment mechanism are close to the edge of the plate to be stacked; S4: The front end of the plate to be stacked contacts the front baffle, the front baffle rotates around the vertical axis, the limiting block compresses the fourth spring, the second section of the shaft tube moves relative to the first section of the shaft tube, the third spring provides the restoring force, and the front side of the plate to be stacked is limited. S5: The rotation of the front baffle causes the force rod to move. The force rod pushes the push rod along the limit rail sleeve through the crank arm shaft. The push rod drives the vertical push plate, sliding rod and push shaft sleeve to move. The push shaft sleeve drives the positive frame to move along the horizontal axis. After the fan plate adjusts the contact angle through the steering shaft, it avoids, blocks and pushes back the rear side of the plate to be stacked. S6: The vertical pusher moves the convex rod, the convex rod pushes the actuating plate to move and rotate along the screw sleeve, the actuating plate pushes the driving folding plate, the driving folding plate moves the side push frame towards the side of the plate to be stacked, the slide moves along the first sliding shaft and compresses the first spring, thus completing the side alignment of the plate to be stacked. S7: After the first, second, and third alignment mechanisms complete the alignment, the second motor drives the vertical conveyor belt to run, which, together with the lower pressure frame, horizontal conveyor belt, and lateral conveyor belt, completes the lifting, transfer, and stacking of the plates to be stacked. Each spring drives the corresponding component to reset, and the next stacking cycle begins.

[0016] Furthermore, the front limiting in S4, the rear push in S5, and the lateral alignment in S6 occur sequentially according to the force sequence after the workpiece enters the stacking station, or they occur in conjunction during the continuous entry of the workpiece; the third spring, the second spring, the first spring, and the fourth spring are respectively used to drive the front baffle, the forward frame, the side push frame, and the toggle piece to reset after the corresponding alignment action is completed.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention forms a front alignment link through a front baffle, shaft groove, right-angle sleeve, first shaft tube, second shaft tube, third spring, limiting block, fourth spring, and auxiliary plate. After the plate enters the stacking area and contacts the front baffle, the front baffle rotates around the vertical axis, the limiting block compresses the fourth spring, and the right-angle sleeve moves up and down with the second shaft tube. The front contact force is converted into a yielding force and a restoring force, so that the front end of the plate is limited during entry, docking, and stacking, reducing front end misalignment, impact, and jamming, and providing a position reference for subsequent side pushing, pressing, and lifting stacking.

[0018] 2. This invention forms a rear alignment link through a rear curved tube, a horizontal shaft, a forward frame, a second spring, a flip plate, a steering shaft, a fan plate, a force-bearing rod, a crank arm shaft, a push rod, a limiting rail sleeve, and a vertical push plate. When the front baffle is pressed, it drives the force-bearing rod to move. The crank arm shaft pushes the push rod to move along the limiting rail sleeve. The vertical push plate drives the sliding rod and the push shaft sleeve to move. The forward frame moves away from or closer to the plate. The fan plate adjusts the contact angle so that the rear side of the plate is blocked, avoids, pushes back, and resets in coordination, solving the rear offset problem. This ensures that the plate forms a rear limit after entering the workstation, preventing the stacking edge from retreating.

[0019] 3. This invention forms a lateral alignment link through a rectangular notch, a first sliding shaft, a sliding plate, a first spring, a driving folding plate, a side push frame, a toggle piece, a screw sleeve, a fourth spring, and a protruding rod. When the vertical push piece moves, it drives the protruding rod to act on the toggle piece. The toggle piece rotates along the screw sleeve. The driving folding plate drives the side push frame to move closer to the side of the plate. The sliding plate is guided along the first sliding shaft. The first spring resets after the external force is released, so that the two sides of the plate are aligned before stacking, solving the lateral deviation between layers and the misalignment of the edges, reducing the time for manual adjustment and the number of downtimes, and realizing the formation of the reference on both sides.

The second alignment mechanism includes a back curved tube 35, which is vertically arranged on the other side of the bottom of the auxiliary plate 15. A third alignment mechanism is provided at one end of the auxiliary plate 15. The third alignment mechanism includes a rectangular notch 19, which is opened in the middle of the surface of the auxiliary plate 15. The top of the erecting frame 7 is provided with a top frame 45, and a rotating rod is provided inside the top frame 45. A second motor 46 is provided on one side of the rotating rod, and a vertically oriented transmission belt 48 is provided on the other side of the second motor 46. The bottom of the erecting frame 7 is provided with a bottom frame 10, and a first electric control drive box 8 is provided on both sides of the bottom frame 10. The stacking method includes the following steps: S1: The plate to be stacked is fed into one side of the gantry 1. The first motor 3 drives the horizontal transmission belt 47 to run, so that the plate to be stacked enters the stacking station along the length of the gantry 1. S2: After the stacked plate is moved to the corresponding position of the limit block 44, it stops moving forward. The first placement platform 11 or the second placement platform 12 receives the stacked plate, and the lower pressure frame 49 limits the upper part of the stacked plate. S3: The side groove plate 2 drives the side support plate 6, the top frame plate 13 and the auxiliary plate 15 to move through the adapter sliding shaft, so that the first alignment mechanism, the second alignment mechanism and the third alignment mechanism are close to the edge of the plate to be stacked. S4: The front end of the plate to be stacked contacts the front baffle 33, the front baffle 33 rotates around the vertical axis, the limiting block 44 compresses the fourth spring 43, the second section of shaft tube 27 moves relative to the first section of shaft tube 14, the third spring 28 provides the restoring force, and the front side of the plate to be stacked is limited. S5: The rotation of the front baffle 33 drives the force rod 31 to move. The force rod 31 pushes the push rod 25 along the limit rail sleeve 23 through the crank arm shaft 29. The push rod 25 drives the vertical push plate 22, the sliding rod 40 and the push shaft sleeve 41 to move. The push shaft sleeve 41 drives the positive frame 5 to move along the horizontal axis 21. After the fan plate 4 adjusts the contact angle through the steering shaft 30, it avoids, blocks and pushes back the rear side of the plate to be stacked. S6: The vertical pusher 22 drives the convex rod to move, the convex rod pushes the actuating plate 39 to move and rotate along the screw sleeve 42, the actuating plate 39 pushes the driving folding plate 38, the driving folding plate 38 drives the side pusher frame 34 to move to the side of the plate to be stacked, the slide plate 18 moves along the first sliding shaft 17 and compresses the first spring 16, thus completing the side alignment of the plate to be stacked. S7: After the first alignment mechanism, the second alignment mechanism and the third alignment mechanism complete the alignment, the second motor 46 drives the vertical transmission belt 48 to run, which, together with the lower pressure frame 49, the horizontal transmission belt 47 and the lateral transmission belt 50, completes the lifting, transfer and stacking of the plates to be stacked. Each spring drives the corresponding component to reset and enters the next stacking cycle. The gantry platform 1 serves as the supporting foundation for the stacking alignment device, supporting the upper frame 9, the erecting frame 7, the first placement platform 11, the second placement platform 12, and the stacking alignment device. The upper frame 9 is located on top of the gantry platform 1 and is used to install the horizontal conveyor belt 47. When the stacked pieces enter the gantry platform 1 from one side of the device, the first motor 3 drives the horizontal conveyor belt 47 to move, causing the stacked pieces to move along the length of the gantry platform 1 until they reach the corresponding position of the limiting block 44. The purpose of the limiting block 44 is to limit the entry position of the stacked pieces, preventing them from moving forward after reaching their position, thus providing a workstation reference for subsequent front, rear, and lateral alignment.

[0024] The first placement platform 11 and the second placement platform 12 are respectively located on both sides inside the gantry platform 1 to support the weight of the receiving plate parts during entry, parking, lifting and stacking. The lower pressure frame 49 is located directly above the first placement platform 11, and the two ends of its inner side are provided with lateral conveyor belts 50. When the plate parts to be stacked are moved to the stacking station, the lower pressure frame 49 is used to limit the upper part of the plate parts to be stacked, and the lateral conveyor belts 50 are used to cooperate with the movement of the plate parts to be stacked on both sides, so that the plate parts to be stacked will not tilt, shift or fall off the placement platform when they are pushed and lifted.

[0025] The erecting frame 7 is located on one side of the top of the gantry platform 1, and the top frame 45 is located on the top of the erecting frame 7. The second motor 46 drives the vertical transmission belt 48 through a rotating rod, enabling the lifting component or stacking moving component to rise and fall vertically. When the stacked pieces are in place and aligned, the vertical transmission belt 48 drives the lifting structure to rise, lifting the stacked pieces from the first placement platform 11 or the second placement platform 12. Then, in conjunction with the horizontal transmission belt 47 and the lateral transmission belt 50, the transfer and stacking are completed. The first electric control drive box 8 is located on both sides of the bottom frame 10 and is used to control the start and stop of the first motor 3, the second motor 46, and each transmission belt, so that the stacked pieces can sequentially complete the entry, positioning, alignment, lifting, transfer, and stacking.

[0026] Side slot plate 2 is installed on one side of upper frame 9, and an adapter slide shaft is set inside it. Side support plate 6 is sleeved on the outside of the adapter slide shaft, so that the side support plate 6 can move along the adapter slide shaft. The purpose of the side support plate 6 is to provide a mounting base for top frame plate 13, auxiliary plate 15 and three sets of alignment mechanisms. When the specifications or entry position of the plate to be stacked changes, the side support plate 6 can drive the top frame plate 13 and auxiliary plate 15 to adjust their positions, so that the first alignment mechanism, the second alignment mechanism and the third alignment mechanism can all be close to the edge of the plate to be stacked. Top frame plate 13 is used to connect the first alignment mechanism, and auxiliary plate 15 is used to connect the second alignment mechanism and the third alignment mechanism, so that the alignment actions in the three directions can occur sequentially around the same plate to be stacked, thereby solving the problems of uneven front end, offset rear end and misaligned side after the plate enters the stacking station.

[0027] Example 1: As Figures 1 to 11 As shown, the first alignment mechanism also includes a front baffle 33, a right-angle sleeve 32, a fourth spring 43, a limiting block 44, a third spring 28, a second section of shaft tube 27, and a shaft groove 26. The second section of shaft tube 27 is vertically slidably arranged inside the first section of shaft tube 14. The third spring 28 is sleeved on the outside of the second section of shaft tube 27. A right-angle sleeve 32 is sleeved on one end of both the first section of shaft tube 14 and the second section of shaft tube 27. A vertical shaft is provided at the middle of one end of the right-angle sleeve 32. A shaft groove 26 is provided on the outside of the vertical shaft. A front baffle 33 is provided on the outside of the shaft groove 26. A limiting block 44 is provided on one side of the front baffle 33. A fourth spring 43 is provided on the outside of the limiting block 44. An auxiliary plate 37 is provided on one end of the fourth spring 43. The first alignment mechanism is used to limit the front of the workpiece after it enters the stacking station. After the workpiece enters the gantry 1 along the horizontal conveyor belt 47, its front end first contacts the front baffle 33. After being pushed by the workpiece, the front baffle 33 rotates through the shaft groove 26 and the vertical axis at one end of the right-angle sleeve 32. The purpose of the rotation of the front baffle 33 is to convert the horizontal impact force of the workpiece into a rotational avoidance force, so that the front baffle 33 can both block the workpiece from the front and prevent the end of the workpiece from hitting or getting stuck due to rigid obstruction.

[0028] When the front baffle 33 rotates, the limiting block 44 on one side of it simultaneously compresses the fourth spring 43, one end of which is supported by the auxiliary plate 37. The purpose of the fourth spring 43 is to provide buffering and return force for the front baffle 33. When the plate to be stacked continues to enter or is lifted, the front baffle 33 can retract under force. When the plate to be stacked leaves the front baffle 33, the fourth spring 43 releases its elastic force, pushing the limiting block 44 and the front baffle 33 to reset, so that the next plate to be stacked can still obtain the same front reference when it enters.

[0029] The first section of the shaft tube 14 is located at the bottom of the top frame plate 13, the second section of the shaft tube 27 is vertically slidably located inside the first section of the shaft tube 14, and the third spring 28 is sleeved on the outside of the second section of the shaft tube 27. The purpose of the design of the first section of the shaft tube 14 and the second section of the shaft tube 27 is to provide vertical movement space for the right-angle sleeve rod 32. When plates of different thicknesses or heights are entered, the right-angle sleeve rod 32 can move vertically with the second section of the shaft tube 27, so that the contact height of the front baffle 33 matches the front end position of the plate to be stacked. The third spring 28 is used to push the second section of the shaft tube 27 to reset after the external force is lost, so that the first alignment mechanism returns to its initial height after each front limit.

[0030] After the workpiece enters the stacking station, it contacts the front baffle 33. The front baffle 33 rotates around the vertical axis, and the limiting block 44 compresses the fourth spring 43. The right-angle sleeve 32 drives the second section of the shaft tube 27 to move up and down according to the height of the workpiece. The third spring 28 absorbs the vertical displacement and provides a restoring force. Through the above actions, the front end of the workpiece is limited to a set position, solving the problems of the workpiece continuing to move forward due to inertia after entering the station, uneven front edge lines, and end collisions.

[0031] Example 2: Figures 1 to 11As shown, the second alignment mechanism also includes a fan blade 4, a forward frame 5, a second spring 20, a horizontal shaft 21, a flipping piece 36, a force-bearing rod 31, a steering shaft 30, a crank arm shaft 29, a push rod 25, a positioning notch 24, a limiting rail sleeve 23, and a vertical push piece 22. A horizontal shaft 21 is provided at one end of the rear curved tube 35. The forward frame 5 is sleeved outside the horizontal shaft 21. A second spring 20 is sleeved on the outer surface of one end of the horizontal shaft 21. Flipping pieces 36 are rotatably mounted at the upper and lower ends of one side of the forward frame 5. A steering shaft 30 is rotatably mounted at one end of the flipping piece 36. One end of the steering shaft 30 is provided with a fan blade 4. The positioning notch 24 is opened on the surface of the attached plate 37 at one end of the fourth spring 43. The inner side of the positioning notch 24 is provided with a limit rail sleeve 23. The inner side of the limit rail sleeve 23 is vertically provided with a push rod 25. One end of the push rod 25 is provided with a vertical push piece 22. The other end of the push rod 25 is provided with a crank arm shaft 29. One end of the crank arm shaft 29 is provided with a force-bearing rod 31. One side of the vertical push piece 22 is provided with a sliding rod 40. The push shaft sleeve 41 is located outside the connection between the positive frame 5 and the horizontal shaft 21. The second alignment mechanism is used to align the rear and back edges of the plates to be stacked by avoiding, blocking, and pushing them back. A curved back tube 35 is vertically mounted at the bottom of the auxiliary plate 15, used to mount the second alignment mechanism on the back side of the plates to be stacked. A horizontal axis 21 is located at one end of the curved back tube 35, and a forward frame 5 is fitted outside the horizontal axis 21, allowing the forward frame 5 to move laterally along the horizontal axis 21. The horizontal axis 21 and the forward frame 5 are designed to form a movable stop frame that can approach or move away from the rear side of the plates to be stacked, so that the plates to be stacked have not only a front reference but also a rear limiting reference before stacking.

[0032] After the front baffle 33 rotates due to the pressure of the plate to be stacked, the movement of the front baffle 33 is transmitted to the force rod 31. The force rod 31 drives the crank arm shaft 29 to rotate, and the crank arm shaft 29 pushes the push rod 25 to move within the limiting sleeve 23. The purpose of the limiting sleeve 23 is to restrict the movement direction of the push rod 25 and prevent the push rod 25 from deflecting during the force process. After the push rod 25 moves, it pushes the vertical push plate 22 to move. The vertical push plate 22 continues to drive the sliding rod 40 and the push shaft sleeve 41 to move, thereby causing the forward frame 5 to move along the horizontal axis 21. Through this linkage, after the front end of the plate to be stacked touches the front baffle 33, the second alignment mechanism can simultaneously perform a rearward avoidance or backward push action, so that the front detection action is converted into a rearward alignment action.

[0033] Flip-plates 36 are provided at the top and bottom ends of one side of the forward frame 5. The flip-plates 36 are connected to the fan blades 4 via the steering shaft 30. The fan blades 4 are designed to form a rotatable contact surface. When there is a local protrusion, edge skew, or entry angle deviation on the rear side of the plate to be stacked, the fan blades 4 can adjust the contact angle via the steering shaft 30, so that its edge first makes flexible contact with the plate to be stacked, and then the rear side of the plate to be stacked is pushed back to the set position by the movement of the forward frame 5. The second spring 20 is sleeved on the outside of the horizontal shaft 21. Its function is to push the push shaft sleeve 41 and the forward frame 5 back to their original positions after the push shaft sleeve 41 and the forward frame 5 lose driving force, so that the second alignment mechanism returns to its initial position after one rear alignment is completed.

[0034] After the plate to be stacked touches the front baffle 33, the front baffle 33 drives the force rod 31 to move. The force rod 31 drives the crank arm shaft 29 to rotate. The crank arm shaft 29 pushes the push rod 25 to move along the limiting rail sleeve 23. The push rod 25 drives the vertical push plate 22 to move. The vertical push plate 22 drives the sliding rod 40 and the push shaft sleeve 41 to move along the horizontal axis 21. The push shaft sleeve 41 drives the positive frame 5 to move closer to or away from the rear side of the plate to be stacked. The fan blade 4 contacts the rear side of the plate to be stacked after adjusting its angle through the steering shaft 30. Through the above actions, the rear side of the plate to be stacked is corrected, which solves the problem that the front side is in place but the rear side is still offset, and the rear edge lines between layers are inconsistent after stacking.

[0035] Example 3: Figures 1 to 11 As shown, the third alignment mechanism also includes a side push frame 34, a drive folding plate 38, a toggle piece 39, a screw sleeve 42, a fourth spring 43, a first sliding shaft 17, a first spring 16, and a sliding plate 18. The first sliding shaft 17 is provided on the inner side of the rectangular notch 19, and the sliding plate 18 is sleeved on the outer side of the first sliding shaft 17. The first spring 16 is provided at one end of the connection between the sliding plate 18 and the first sliding shaft 17. The drive folding plate 38 is provided at one end of the sliding plate 18. The side push frame 34 is provided on one side of the drive folding plate 38. The toggle piece 39 is provided on the lower side of the back of the drive folding plate 38. The fourth spring 43 is provided on the inner side of the toggle piece 39. The screw sleeve 42 is provided on the inner side of the fourth spring 43. A protruding rod is provided at one end of the back of the toggle piece 39. The protruding rod is fixedly connected to one end of the vertical push piece 22. The third alignment mechanism is used to align the two sides of the boards to be stacked. A rectangular notch 19 is formed in the middle of the surface of the auxiliary board 15. A first sliding shaft 17 is set inside the rectangular notch 19, and a sliding plate 18 is fitted outside the first sliding shaft 17, allowing the sliding plate 18 to move along the first sliding shaft 17. The rectangular notch 19 is designed to provide space for the sliding plate 18, and the first sliding shaft 17 is designed to limit the movement trajectory of the sliding plate 18, ensuring that the sliding plate 18 can only move in a set direction, thereby preventing the side push frame 34 from tilting vertically or swaying laterally when aligning the boards to be stacked.

[0036] When the vertical pusher 22 moves, it drives the protruding rod connected to one end to move. The protruding rod pushes the actuating plate 39, which moves and rotates under the cooperation of the threaded sleeve 42 and the fourth spring 43. The threaded sleeve 42 is designed to provide a helical guide for the actuating plate 39, so that the actuating plate 39 does not move in a simple linear manner, but rotates during the movement. The fourth spring 43 is used to provide elastic support and a restoring force for the actuating plate 39. When the actuating plate 39 rotates, its outer side pushes the driving folding plate 38. The driving folding plate 38 drives the side push frame 34 to move closer to the side of the plate to be stacked, thereby converting the linear movement of the vertical pusher 22 into the lateral pushing action of the side push frame 34.

[0037] The side push frame 34 is designed to directly contact the side of the plate to be stacked. When the plate to be stacked enters the workstation on the horizontally oriented conveyor belt 47, if its left and right sides do not correspond to the stacking baseline, the side push frame 34 moves inward under the drive of the drive folding plate 38, pushing the side of the plate to be stacked towards the set position. When the slide plate 18 moves outside the first slide shaft 17, the first spring 16 is compressed; when the two sides of the plate to be stacked are aligned and the external driving force is released, the first spring 16 pushes the slide plate 18, the drive folding plate 38 and the side push frame 34 to reset, providing an initial position for the lateral alignment of the next plate to be stacked.

[0038] In the second alignment mechanism, the vertical pusher 22 moves, causing the convex rod to move. The convex rod pushes the actuating plate 39, which generates a spiral motion along the threaded sleeve 42 and compresses the fourth spring 43. When the actuating plate 39 rotates, it pushes the driving folding plate 38. The driving folding plate 38 drives the side pusher frame 34 to move towards the side of the plate to be stacked. After the side pusher frame 34 contacts the plate to be stacked, it pushes its side back to the set position. The slide plate 18 moves along the first sliding shaft 17 and compresses the first spring 16. After alignment is completed, the first spring 16 drives the side pusher frame 34 to reset. Through the above actions, the plate to be stacked is laterally corrected before stacking, solving the problems of left and right deviation between plate layers, edge misalignment, and manual secondary alignment.
