[0014] The application further discloses a hierarchical stacking method for wood board packaging boxes, which adopts the hierarchical stacking equipment for wood board packaging boxes and comprises the following steps.

[0015] S1: first, place the tray on the top of the tray placing frame, then move the equipment to one end of the conveying belt to make the support plate flush with the conveying belt, and then move multiple packaging boxes to the top of the support plate through the operation of the conveying belt;

[0016] S2: then, start the motor, rotate the adjusting lead screw relative to the support block through the operation of the motor, so that the movable sliding block pushes the connecting sliding block to move upward, and correct the packaging boxes on the top of the support plate through the adjusting and correcting element in the process.

[0017] S3: when the connecting slider moves to the highest point, the first telescopic cylinder is started, and the dial gear is rotated by 180 degrees through the extension of the first telescopic cylinder, so that the supporting plate moves to the top of the tray placing rack;

[0018] S4: then the reverse rotation of the adjusting screw is driven by the motor to make the movable slider move down, and the U-shaped support frame contacts the tray on the tray placing rack with the downward movement of the first return spring, and then the supporting plate falls on the top of the tray on the tray placing rack through the cooperation of the staggered moving piece and the limiting unit;

[0019] S5: then the supporting plate is restored through the operation of the motor and the first telescopic cylinder, and thus the package boxes are stably stacked on the tray on the top of the tray placing rack.

[0020] Compared with the prior art, the beneficial effects of the present application are:

[0021] 1. By setting the position correction piece, when the movable slider drives the connecting slider to move up, the second telescopic cylinder will first extend, so that the first compression roller corrects and limits the multiple package boxes placed on the top of the supporting plate in the front and back directions, and similarly, through the operation of the third telescopic cylinder, the second L-shaped swing frame swings relative to the mounting frame, and at the same time, the second compression roller corrects and limits the multiple package boxes placed on the top of the supporting plate in the left and right directions. When the supporting plate turns to the top of the tray, the center axis of the multiple package boxes as a whole is coaxial with the center axis of the tray, so that the multiple package boxes fall on the center of the tray when they fall on the tray, thereby making the force on the tray uniform, preventing the package boxes stacked on the top of the tray from falling during subsequent transportation, and improving the stability of the stacked package boxes;

[0022] 2. By setting the staggered moving piece, when the turntable rotates by 180 degrees, the trapezoidal block is located above the second piston rod. After the supporting plate contacts the top of the package boxes stacked on the tray, the supporting plate is hindered by the package boxes on the tray. At this time, the movable slider moves relative to the connecting slider when it moves down, and the trapezoidal block extrudes the second piston rod with the downward movement of the movable slider, so that the water solution in the first piston sleeve enters the inside of the second piston sleeve through the connecting hose, and the cotter is buckled into the insertion hole, so that the first piston rod drives the supporting plate to move away from the U-shaped support frame. At this time, the package boxes on the top of the supporting plate are limited by the position correction piece, so that the supporting plate is separated from the bottom of the package boxes, so that the package boxes on the top of the original supporting plate fall above the tray, so as to realize the stacking of the package boxes, and also improve the precision of the stacking of the package boxes;

[0023] 3. By setting the limiting unit, when the first compression roller swings towards the center axis of the U-shaped support frame along with the first L-shaped swing frame, the first compression roller drives the limiting rod to move horizontally through the shift pin, when the first compression roller is attached to the top of the supporting plate and the packaging box, the partition plate is located below the first compression roller, so that the first compression roller and the partition plate are always on a vertical line, when the supporting plate moves above the stacked packaging box, the partition plate contacts the packaging box below the supporting plate, when the supporting plate moves relative to the U-shaped support frame, the partition plate will limit the packaging box below the supporting plate and already stacked, so as to prevent the supporting plate from driving the already stacked packaging box to shake through friction when moving, thereby improving the stability of the packaging box during stacking.

[0040] Please refer to Figure 6 , Figure 9 , the first movable contact piece 843 and the second movable contact piece 846 are electrically connected to the external power supply through wires, and the first static contact piece 844 and the second static contact piece 845 are connected to the second telescopic cylinder 827 and the third telescopic cylinder 828 through wires respectively.

[0042] Please refer to Figure 5 , Figure 6 , the distance between the first compression roller 823 and the mounting frame 829 is greater than the distance between the second compression roller 824 and the mounting frame 829.

[0043] In this embodiment: by setting this structure to prevent the first roller 823 and the second roller 824 between the collision in the process of swinging.

[0044] Please refer to Figure 2 , Figure 3 , Figure 7 , the dislocation moving piece includes the first piston sleeve 803 installed at the bottom of the mounting seat 2 and located at one side of the dial gear 807, the top of the first piston sleeve 803 is inserted with the second piston rod 837 extending into the inside of the first piston sleeve 803, the second piston rod 837 is provided with the third reset spring 836 connected with the first piston sleeve 803, the side away from the U-shaped support frame 805 of the movable sliding block 808 is installed with the trapezoidal block 815 extending to the below of the mounting seat 2, the outside of the first piston sleeve 803 is inserted with the clamping frame 835, the top of the second piston rod 837 is installed with the positioning frame 840, the side away from the second piston rod 837 of the positioning frame 840 is provided with the insertion hole 839, the inside of the clamping frame 835 is provided with the fourth reset spring 838 connected with the first piston sleeve 803, the outer wall of the clamping frame 835 is installed with the clamping pin 841 located at the inside of the positioning frame 840, both sides of the U-shaped support frame 805 are installed with the second piston sleeve 816, the inside of the second piston sleeve 816 is inserted with the first piston rod 817 extending to the outside of the second piston sleeve 816 and connected with the support plate 804, the end away from the first piston rod 817 of the second piston sleeve 816 is connected with the bottom of the first piston sleeve 803 through the connecting hose 813.

[0045] In this embodiment: when the movable slider 808 rises relative to the support block 6, the inclined surface of the trapezoidal block 815 separates from the locking frame 835. At this time, under the elastic restoring force of the fourth return spring 838, the locking frame 835 pushes the locking pin 841 to contact the inner wall of the positioning frame 840. When the turntable 5 rotates 180 degrees, the trapezoidal block 815 is located above the second piston rod 837. After the support plate 804 contacts the top of the packaging boxes stacked on the pallet, the support plate 804 is obstructed by the packaging boxes on the pallet. At this time, when the movable slider 808 moves down, it will move relative to the connecting slider 801. As the movable slider 808 moves down, the trapezoidal block 815 squeezes the second piston rod 837, thereby allowing the aqueous solution inside the first piston sleeve 803 to enter the interior of the second piston sleeve 816 through the connecting hose 813. At the same time, the locking pin 841 engages with the insertion hole 839. The first piston rod 817 drives the support plate 804 to move away from the U-shaped support frame 805. At this time, the packaging box on the top of the support plate 804 is limited by the adjustment and correction component, causing the support plate 804 to separate from the bottom of the packaging box. This allows the packaging box on the top of the support plate 804 to fall onto the pallet, thereby realizing the stacking of the packaging boxes and improving the stacking accuracy between the packaging boxes. When the movable slider 808 moves to the initial position, the trapezoidal block 815 will press against the locking frame 835 through the inclined surface, causing the locking pin 841 to separate from the insertion hole 839. This allows the second piston rod 837 to move upward relative to the first piston sleeve 803 under the elastic restoring force of the third return spring 836, thereby drawing the aqueous solution inside the second piston sleeve 816 into the first piston sleeve 803, thus allowing the support plate 804 to be inserted into the U-shaped support frame 805.

[0046] Please refer to this carefully. Figure 2 , Figure 3 The top of the mounting base 2 has two through holes that fit into the trapezoidal block 815. The two through holes are symmetrically arranged along the vertical central axis of the turntable 5.

[0047] In this embodiment: by setting this structure, the trapezoidal block 815 is provided with a space for movement, so that the trapezoidal block 815 passes through the through hole and contacts the locking frame 835 and the second piston rod 837.

[0048] Please refer to this carefully. Figure 7 The end of the locking pin 841 away from the locking frame 835 is rotatably connected to a ball bearing via a rotating shaft, and the diameter of the insertion hole 839 is equal to that of the locking pin 841.

[0049] In this embodiment, this structure is used to reduce the friction between the positioning frame 840 and the locking pin 841, thereby preventing wear on the locking pin 841 or the positioning frame 840, and also improving the stability of the locking frame 835 after the locking pin 841 is inserted into the socket 839.

[0051] In this embodiment: when the first compression roller 823 swings towards the center axis of the U-shaped support frame 805 with the first L-shaped swing frame 825, the first compression roller 823 drives the limiting rod 818 to move horizontally through the shift pin 822, and when the first compression roller 823 is attached to the top of the packaging box on the support plate 804, the partition plate 819 is located below the first compression roller 823, so that the first compression roller 823 and the partition plate 819 are always on a vertical line, and when the support plate 804 moves above the stacked packaging box, the partition plate 819 contacts the packaging box below the support plate 804, and when the support plate 804 moves relative to the U-shaped support frame 805, the partition plate 819 limits the packaging box below the support plate 804 that has been stacked, so as to prevent the packaging box from being shaken by friction when the support plate 804 moves, thereby improving the stability of the packaging box during stacking.

[0052] Please focus on Figure 5 The width of the inside of the straight slot frame 821 is equal to the diameter of the shift pin 822.

[0053] In this embodiment: by setting this structure, the limiting rod 818 and the partition plate 819 move horizontally through the straight slot frame 821 when the first compression roller 823 swings, so as to adjust the position of the partition plate 819.

[0054] The following provides a wood board packaging box stacking method based on the above wood board packaging box stacking device, which specifically includes the following steps:

[0055] S1: first place the tray on the top of the tray placing frame 802, then move the device to one end of the conveyor belt to make the support plate 804 flush with the conveyor belt, and move multiple packaging boxes to the top of the support plate 804 through the operation of the conveyor belt;

[0056] S2: According to the length and width of the spliced packaging boxes, the extension distance of the second and third telescopic cylinders 827 and 828 is adjusted. Then, when the movable sliding block 808 drives the connecting sliding block 801 to move upwards, the bottom of the plug block 812 loses support. At this time, the plug block 812 is pushed downwards relative to the connecting bin 811 by the elastic restoring force of the fifth return spring 842. At this time, the second movable contact piece 846 contacts the second static contact piece 845. At this time, the second telescopic cylinder 827 is first extended. When the second telescopic cylinder 827 is extended, the first rack 830 drives the second spur gear 833 to rotate, so as to make the first L-shaped swing frame 825 swing relative to the mounting frame 829, so that the first compression roller 823 corrects and limits the multiple packaging boxes placed on the top of the support plate 804 in the front-back direction. Similarly, the movement of the plug block 812 makes the first movable contact piece 843 contact the first static contact piece 844, so that the second L-shaped swing frame 826 swings relative to the mounting frame 829, and at the same time, the second compression roller 824 corrects and limits the multiple packaging boxes placed on the top of the support plate 804 in the left-right direction;

[0057] S3: When the connecting sliding block 801 moves to the highest point, the first telescopic cylinder 4 is started. The extension of the first telescopic cylinder 4 drives the shift rack 806 to rotate the shift gear 807 by one hundred and eighty degrees;

[0058] S4: When the support plate 804 turns above the tray, the center axis of the multiple packaging boxes is coaxial with the center axis of the tray, so that the multiple packaging boxes fall on the tray and are located in the center of the tray, so that the tray is evenly stressed, preventing the packaging boxes stacked on the top of the tray from falling during subsequent handling, and improving the stability of the stacked packaging boxes;

[0059] S5: When the first compression roller 823 swings towards the center axis of the U-shaped support frame 805 with the first L-shaped swing frame 825, the first compression roller 823 drives the limiting rod 818 to move horizontally through the shift pin 822. When the first compression roller 823 is in close contact with the packaging boxes on the top of the support plate 804, the partition plate 819 is located below the first compression roller 823, so that the first compression roller 823 and the partition plate 819 are always on a vertical line;

[0060] S6: After the support plate 804 contacts the top of the stacked packaging boxes on the tray, the support plate 804 is hindered by the packaging boxes on the tray, at this time, the movable slider 808 moves relative to the connecting slider 801 when moving downward, the trapezoidal block 815 extrudes the second piston rod 837 when the movable slider 808 moves downward, so that the water solution in the first piston sleeve 803 enters the inside of the second piston sleeve 816 through the connecting hose 813, and the catch pin 841 is buckled into the insertion hole 839, so that the first piston rod 817 drives the support plate 804 to move away from the U-shaped support frame 805, at this time, the packaging boxes on the top of the support plate 804 are limited by the positioning and correcting member, so that the support plate 804 is separated from the bottom of the packaging boxes, and the partition plate 819 limits the packaging boxes that have been stacked below the support plate 804, so as to prevent the packaging boxes that have been stacked from being shaken by friction when the support plate 804 moves, thereby improving the stability of the packaging boxes during stacking, so that the packaging boxes on the top of the original support plate 804 fall onto the tray above, so as to realize the stacking of the packaging boxes, and improve the precision of the stacking of the packaging boxes;

[0061] S7: Then, the support plate 804 is restored by the operation of the motor 3 and the first telescopic cylinder 4, and the above process is repeated to stack the packaging boxes stably on the tray on the top of the tray placing frame 802.

[0062] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
