Description

Technical Field

[0001] The present invention relates to the technical field of stacking devices, and particularly to a stacking device for particle board production. Background Art

[0002] Particle board, also known as chipboard, is produced by cutting various raw materials such as twigs, small-diameter logs, fast-growing wood, and wood chips into fragments of specific specifications. After drying, these fragments are thoroughly mixed with additives such as adhesives, hardeners, and waterproofing agents, and then pressed into artificial boards under specific temperature and pressure conditions. However, the particle arrangement of this board is not uniform, which is one of its physical characteristics. It should be noted that although particle board and solid wood particle board have similar names, they are not the same type of board. Although solid wood particle board has similarities in processing technology with particle board, its quality has been significantly improved, far exceeding that of particle board.

[0003] In the subsequent processing process of particle board, after it is made into semi-finished or finished products, it usually needs to be properly stored. At this time, the stacking equipment plays a key role. It can stack the particle boards neatly, which is not only convenient for transportation but also improves the warehousing efficiency. However, there are still some deficiencies in the existing stacking equipment. For example, the patent publication number is: CN119873367A, an automatic palletizing device for particle board production, including a machine body. A plurality of guide wheels are rotated at the top of the machine body. Slide columns are fixedly connected to the left and right inner walls of the machine body. A base is slidably connected between the two slide columns. Two electric telescopic rails one are fixedly installed on the upper surface of the base. A tray is arranged above the electric telescopic rail one. A plurality of slide rods are fixedly connected to the upper surface of the base. In the present invention, a plurality of suction cups tightly adsorb the particle board, and then the drive motor and the electric telescopic rail two continue to cooperate to place the particle board above the tray. During the process, the exhaust holes continuously discharge gas to clean and dissipate heat from the particle board, thus solving the problem that the existing automatic palletizing equipment cannot stack single boards and is difficult to meet the requirements of the board transfer work between various processes. Specifically, these devices mainly rely on suction cup manipulators to adsorb and place the particle boards on the turnover rack. However, the problem is that due to various factors such as the adsorption accuracy of the suction cup manipulator, the control of the placement force, and the flatness of the surface of the turnover rack, the edges of the particle boards often appear uneven after being placed.

[0004] This uneven phenomenon not only affects the overall aesthetics of the particleboard, but more importantly, it brings great trouble to the subsequent leveling work. At present, this leveling work mainly relies on manual work, and the staff needs to spend a lot of time and energy to adjust the position of each particleboard to ensure that its edges are neat. This undoubtedly increases the workload of the staff, reduces production efficiency, and also increases labor costs. Therefore, the development of a stacking device that can automatically adjust the position of the particleboard and reduce the uneven edge phenomenon after stacking has become a technical problem that needs to be solved urgently in the current industry. Summary of the invention

[0005] The object of the present invention is to provide a stacking device for producing particleboard to solve the problems raised in the above-mentioned background technology.

[0011] Further, the buffer unit includes a nut fixedly sleeved on the upper end of the hollow rod, a spring is wound around the periphery of the hollow rod, and two ends of the spring in the elastic force direction respectively elastically abut against the bottom of the sucker mounting frame and the top of the sucker.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Please refer to Figures 1-8, the present invention provides: a stacking device for particle board production, including a portal-shaped vertical frame 10. A horizontally conveying conveyor belt 1 is installed below the vertical frame 10, and the vertical frame 10 straddles the conveyor belt 1. A truss 11 is installed on the vertical frame 10. A transverse movement seat is horizontally slidably connected to the outer wall of the truss 11 on the side facing the discharge end of the conveyor belt 1 through an installation linear guide slider. A transverse movement frame 2 is vertically slidably connected to the outer wall of the transverse movement seat through an installation linear guide slider. A suction cup mounting frame 5 is installed at the lower end of the transverse movement frame 2. A hollow rod 16 is vertically slidably penetrated through the suction cup mounting frame 5. The lower end of the hollow rod 16 is connected to a suction cup 6 in a penetrating manner. The upper end of the hollow rod 16 is connected to an external air extraction device through a hose. The hollow rod 16, the suction cup 6, and the suction cup mounting frame 5 form a suction cup manipulator, which is used to suck the particle board on the conveyor belt 1. In addition, a nut 17 is fixedly sleeved on the upper end of the hollow rod 16, and a spring 18 is wound around the periphery of the hollow rod 16. The two ends in the elastic force direction of the spring 18 are elastically abutted against the bottom of the suction cup mounting frame 5 and the top of the suction cup 6 respectively; A first rack 3 is horizontally and fixedly connected to the top of the truss 11. A first servo motor 15 is installed on the transverse movement seat. A first gear 14 is fixedly sleeved on the motor shaft of the first servo motor 15. The first gear 14 is externally meshed with the first rack 3. When the motor shaft of the first servo motor 15 rotates, it will drive the first gear 14 to rotate. When the first gear 14 rotates, it will cause the first gear 14 and the first rack 3 to engage and drive, and thus be able to drive the transverse movement seat to move horizontally on the truss 11, that is, be able to move along the width direction of the conveyor belt 1. In addition, a second rack 4 is vertically installed on the suction cup mounting frame 5. A second servo motor 12 is installed on the top of the transverse movement seat. A second gear 13 is fixedly sleeved on the motor shaft of the second servo motor 12. The second gear 13 is externally meshed with the second rack 4. When the motor shaft of the second servo motor 12 rotates, it will drive the second gear 13 to rotate. When the second gear 13 rotates, it will engage and drive with the second rack 4, and thus be able to drive the transverse movement frame 2 to move up and down so that the suction cup 6 can contact the particle board on the conveyor belt 1; A turnover rack 7 is placed on one side of the discharge end of the conveyor belt 1. Rollers can be installed at the bottom of the turnover rack 7. A hinge seat 21 is fixedly connected to the top of the turnover rack 7. A stacking board 9 is rotatably connected to the hinge seat 21 through a pivot. When the stacking board 9 is in a lying state, the stacking board 9 is parallel to the top of the turnover rack 7. Baffles 8 are rotatably connected to two adjacent sides of the stacking board 9. The hinge seat 21 is located between the two baffles 8. An activity seat 22 is hinged to the bottom of the turnover rack 7. A lifting cylinder 19 is installed at the bottom of the activity seat 22. The cylinder rod of the lifting cylinder 19 penetrates through the activity seat 22 and is fixedly connected to a pushing block 24. The pushing block 24 is hinged to the bottom of the stacking board 9. An avoidance groove 23 for the free passage of the pushing block 24 is opened on the turnover rack 7. When the cylinder rod of the lifting cylinder 19 extends and retracts, it will drive the pushing block 24 to move up and down. When the pushing block 24 moves up and down, it will drive the stacking board 9 to swing along the hinge joint with the hinge seat 21; A rotating arm 20 is fixedly connected to the outer wall on the lower side of the baffle 8. A flat push cylinder 25 is horizontally installed at the bottom of the stacking plate 9. The cylinder rod of the flat push cylinder 25 is fixedly connected with a flat push block 26. One end of the flat push block 26 is hinged with a hinge rod 27. The end of the hinge rod 27 far away from the flat push block 26 is hinged to the rotating arm 20. The telescopic movement of the cylinder rod of the flat push cylinder 25 drives the horizontal movement of the flat push block 26. When the flat push block 26 moves horizontally, it will cause the hinge rod 27 to drive the swinging of the rotating arm 20, and then drive the swinging of the baffle 8. In addition, at the top surface position of the stacking plate 9, a covering layer made of stainless steel is specially provided (it should be noted that this stainless steel layer is not shown in the relevant drawings). The stainless steel layer has unique physical properties. Its surface is smooth and flat, and the friction coefficient is relatively low. This property enables the stainless steel layer to significantly reduce the frictional resistance between the particle board and the surface of the stacking plate 9 when the particle board is placed on the surface of the stacking plate 9, thus providing extremely favorable conditions for the sliding of the particle board on the surface of the stacking plate 9 and ensuring that the particle board can move smoothly on the surface of the stacking plate 9.

[0021] The working principle of this embodiment: The worker places the finished or semi-finished particle board after processing on the feeding end of the conveyor belt 1, and the smooth surface of the particle board faces upward. Start the conveyor belt 1. The conveyor belt 1 runs and conveys the particle board to the lower part of the suction cup 6. A sensor is installed on the suction cup mounting frame 5. This sensor is used to detect whether there is a particle board on the conveyor belt 1. When it is detected that a particle board is conveyed to the lower part of the suction cup mounting frame 5, the sensor generates a signal and feeds it back to the external control cabinet. The control cabinet controls the conveyor belt 1 to stop briefly, and then controls the second servo motor 12 to start. When the second servo motor 12 starts, it will cause the second gear 13 and the second rack 4 to engage and drive, and drive the transverse movement frame 2 to move downward, so that the suction cup 6 can contact the particle board. The external air extraction device extracts air from the inside of the suction cup 6, so that the suction cup 6 can adsorb the particle board; Then the control cabinet controls the second servo motor 12 to start. The second servo motor 12 rotates in the reverse direction, and the particle board moves upward. Subsequently, the control cabinet controls the first servo motor 15 to start. The motor shaft of the first servo motor 15 rotates and drives the first gear 14 to rotate. The first gear 14 and the first rack 3 engage, and then drive the transverse movement frame 2 to move above the turnover rack 7. Immediately, the control cabinet controls the second servo motor 12 to start again, so that the transverse movement frame 2 moves downward, and the particle board can be placed on the surface of the stacking plate 9. Additionally, further, sensors can be installed on the turnover rack 7 or the vertical rack 10. The sensors are used to detect the stacking height of the particle board on the stacking plate 9, so that the downward movement stroke of the transverse movement frame 2 decreases successively when placing the particle board next time; After the particleboard is placed on the stacking plate 9, the control cabinet controls the second servo motor 12 to rotate in the reverse direction, so that the transverse moving frame 2 moves upward to the in-place position, and then controls the first servo motor 15 to start, so that the first servo motor 15 rotates, so that the transverse moving frame 2 moves to directly above the conveyor belt 1 to complete the reset action; When the stacking of the particleboard is completed, first start the lifting cylinder 19. The cylinder rod of the lifting cylinder 19 extends and drives the stacking plate 9 to swing slightly upward. Under the action of gravity, the particleboard on the stacking plate 9 will slide in the direction of the hinge seat 21. Since the particleboard located below is affected by the gravity of the upper particleboard, its sliding resistance on the surface of the stacking plate 9 is relatively large. At this time, the control cabinet controls the flat push cylinder 25 to start. The cylinder rod of the flat push cylinder 25 extends, so that the baffle 8 rotates, and the upper end of the baffle 8 swings toward the center side of the stacking plate 9. At the same time, the included angle between the length direction of the baffle 8 and the top surface of the stacking plate 9 is an acute angle. In this way, the upper end of the baffle 8 has a blocking effect on the upper particleboard, so that the sliding stroke of the upper particleboard is smaller than that of the lower particleboard. The purpose of this is to prevent the sliding stroke of the upper particleboard from being greater than that of the lower particleboard, which may cause the upper particleboard and the lower particleboard to collapse. After the stacking plate 9 swings upward to the fixed position, the cylinder rod of the flat push cylinder 25 shortens, so that the baffle 8 rotates in the reverse direction until the length direction of the baffle 8 is perpendicular to the top surface of the stacking plate 9. In this way, the baffle 8 can trim the adjacent two side edges of the particleboard. After the edges of the particleboard are basically neat, the cylinder rod of the lifting cylinder 19 shortens and resets, thereby driving the stacking plate 9 to swing downward and reset. At this time, the turnover frame 7 can be transported away by an external transportation device, thereby completing the stacking operation of the particleboard.

[0022] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The description method of this specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0023] Therefore, the above description is only a preferred embodiment of the present application and is not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
