Description
Technical Field
[0001] The present invention relates to the technical field of automatic sheet stacking, and particularly to an automatic sheet stacking device. Background Art
[0002] In the fields of mechanical transmission and automatic packaging, the high-speed slitting and stacking of sheet materials (such as tinplate sheets, with a thickness usually of 0.18 mm - 0.2 mm) are one of the key processes. Such sheets are widely used in industries such as food packaging and electronic devices, and their surface quality and geometric accuracy directly affect subsequent processing and product performance. However, during the stacking process after high-speed slitting, due to the low stiffness of the sheets themselves and being easily interfered by external forces, defects such as edge deformation and surface scratches often occur. Especially in traditional stacking devices, when the slit sheets directly fall and stack through the conveying equipment, irreversible damage is easily caused due to impacts, friction, or uneven stacking pressure.
[0003] Therefore, we have designed an automatic sheet stacking device to solve the above problems. Summary of the Invention
[0004] The purpose of the present invention is to provide an automatic sheet stacking device to solve the problems raised in the above background art.
[0005] To solve the above technical problems, an automatic sheet stacking device provided by the present invention includes a mounting base. A transport member is connected inside the mounting base. A flywheel roller is rotatably connected inside the mounting base, and the position of the flywheel roller corresponds to the discharge end of the transport member. A scissor lift is arranged on one side of the mounting base, and a material collection frame is connected to the top of the scissor lift.
[0006] Further, the transport member includes a driving roller, a driven roller, and a conveyor belt. The conveyor belt is sleeved between the driving roller and the driven roller for transporting the sheets. The diameter of the flywheel roller is larger than that of the driven roller, so that the sheets move in a parabolic shape.
[0007] Further, the material collection frame includes two side plates that are symmetrically connected to the top of the scissor lift. A rear baffle is fixedly connected between the two side plates, and a front baffle is slidably connected.
[0008] Further, one side of the front baffle is connected with a plurality of return springs, the other ends of the return springs are connected with a connecting plate. An installation plate is arranged on one side of the scissor lift, the connecting plate is slidably connected to the installation plate, and a cylinder is connected to the installation plate. The other end of the cylinder is connected to the connecting plate, and the cylinder is inclined.
[0009] Further, two symmetrically arranged fixing plates are connected to the scissor lift. A reinforcing plate is connected to the mounting plate, and the other end of the reinforcing plate is connected to the two fixing plates.
[0010] Further, a sliding plate is connected to the connecting plate, and the sliding plate is slidably connected to the fixing plate.
[0011] Further, a photoelectric detection component is connected to one side of the side plate. The detection end of the photoelectric detection component extends into the material collection box, and the photoelectric detection component is electrically connected to the scissor lift.
[0012] Further, a servo motor is connected to one side of the mounting base. The driving end of the servo motor is connected to one end of the flywheel roller through a coupling to drive the flywheel roller to rotate.
[0013] The cut thin plate is placed on the conveyor belt and is conveyed forward as the conveyor belt runs. When the thin plate reaches the discharge end of the transport member, since the diameter of the flywheel roller is larger than that of the passive roller, the running trajectory of the conveyor belt changes when passing through the flywheel roller, driving the thin plate to run in a parabola, and then the thin plate falls into the material collection box at the top of the scissor lift.
[0014] Further, when the thin plate falls into the material collection box, it will first hit the front baffle. The front baffle is connected to the connecting plate through a plurality of return springs. The return springs are elastically deformed under the impact force, absorbing and buffering the kinetic energy of the impact of the thin plate. At the same time, the inclined cylinder is subjected to the reaction force generated by the thin plate hitting the front baffle. One end of the cylinder is connected to the connecting plate, and the other end is connected to the mounting plate. The connecting plate can slide on the mounting plate. The cylinder expands and contracts according to the reaction force, pushing the connecting plate to slide on the mounting plate, and then driving the front baffle to move backward, pushing the buffered thin plate backward against the rear baffle to complete the stacking and positioning of the thin plate once.
[0015] Further, during the stacking process, the photoelectric detection component on one side of the side plate of the material collection box continuously detects the stacking height of the thin plates in the box. If the stacking height reaches a certain level, the photoelectric detection component will send a signal to control the scissor lift to descend a certain height to facilitate continuous stacking operations.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. By using the structure where the diameter of the flywheel roller is larger than that of the passive roller, the conveyor belt drives the thin plate to move in a parabolic shape, changing the direct falling motion mode of the thin plate, dispersing the impact force when the thin plate falls, avoiding rigid collisions with the stacking surface or other components, and reducing the possibility of edge deformation and surface scratches. Secondly, the front baffle, return spring, and cylinder in the material collection frame cooperate. When the thin plate falls, the return spring buffers the impact kinetic energy, and the cylinder pushes the front baffle to gently position the thin plate, further protecting the thin plate from damage and ensuring the quality of the thin plate.
[0018] 2. The cooperation between the photoelectric detection component and the scissor lift can automatically adjust the height of the lift according to the stacking height, ensuring that the stacking height of each layer of thin plates is consistent, avoiding problems such as messy stacking and uneven stacking pressure, and making the stacking more neat and orderly.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 of 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 shall fall within the protection scope of the present invention.
[0026] Embodiment 1
[0027] Refer to Figures 1 - 5As shown in the figure, an automatic thin plate stacking device includes a mounting base 1. A transport member 2 is connected inside the mounting base 1. A flywheel roller 3 is rotatably connected inside the mounting base 1. The position of the flywheel roller 3 corresponds to the discharge end of the transport member 2. A scissor lift 4 is provided on one side of the mounting base 1. A material collection frame is connected to the top of the scissor lift 4. The transport member 2 includes a driving roller, a driven roller and a conveyor belt. The conveyor belt is sleeved between the driving roller and the driven roller for transporting thin plates. The diameter of the flywheel roller 3 is larger than that of the driven roller, so that the thin plates move in a parabola. One side of a side plate 5 is connected with a photoelectric detection member 15. The detection end of the photoelectric detection member 15 extends into the material collection frame. The photoelectric detection member 15 is electrically connected to the scissor lift 4.
[0028] During specific implementation, the driving roller drives the sleeved conveyor belt to operate, and then drives the driven roller to rotate synchronously. The cut thin plates are placed on the conveyor belt and are transported forward as the conveyor belt runs. When the thin plates reach the discharge end of the transport member 2, since the diameter of the flywheel roller 3 is larger than that of the driven roller, when the conveyor belt passes over the flywheel roller 3, the running track changes, driving the thin plates to move in a parabola, and then falling into the material collection frame at the top of the scissor lift 4. During the stacking process, if the stacking height of the thin plates in the material collection frame reaches a certain level, the corresponding photoelectric detection member 15 will send a signal to control the scissor lift 4 to descend a certain height for continuous stacking operation until the entire stacking task is completed. Compared with the direct falling and stacking of thin plates in traditional stacking devices, the flywheel roller 3 makes the thin plates move in a parabola, effectively dispersing the impact force when the thin plates fall, avoiding the rigid collision between the thin plates and the stacking surface or other components, and greatly reducing the probability of edge deformation and surface scratching of the thin plates.
[0029] Refer to Figures 1 - 5 As shown in the figure, the material collection frame includes two side plates 5 that are symmetrically connected to the top of the scissor lift 4. A rear baffle 6 is fixedly connected between the two side plates 5. A front baffle 7 is slidably connected. One side of the front baffle 7 is connected with a plurality of return springs 8. The other ends of the return springs 8 are connected with a connecting plate 10. An installation plate 9 is provided on one side of the scissor lift 4. The connecting plate 10 is slidably connected to the installation plate 9. A cylinder 11 is connected to the installation plate 9. The other end of the cylinder 11 is connected to the connecting plate 10. The cylinder 11 is inclined.
[0030] During specific implementation, when the cut thin plates are transported by the transport member 2 and fall into the material collection frame in a parabola, the thin plates will first hit the front baffle 7. Since the front baffle 7 is connected to the connecting plate 10 through a plurality of return springs 8, the return springs 8 will undergo elastic deformation when receiving the impact force of the thin plates, absorbing and buffering the kinetic energy of the impact of the thin plates, so that the impact force of the thin plates is dispersed and weakened.
[0031] When the thin plate impacts the front baffle 7, the inclined cylinder 11 will be subjected to corresponding forces. Since one end of the cylinder 11 is connected to the connecting plate 10 and the other end is connected to the mounting plate 9, and the connecting plate 10 can slide on the mounting plate 9, the cylinder 11 will perform telescopic actions according to the reaction force generated by the impact of the thin plate. As the cylinder 11 expands and contracts, it will push the connecting plate 10 to slide on the mounting plate 9, thereby driving the front baffle 7 to move backward, pushing the buffered thin plate backward against the rear baffle 6, and completing the stacking and positioning of the thin plate once.
[0032] Refer to Figures 1 - 5 , two symmetrically arranged fixing plates 12 are connected to the scissor lift 4, and a reinforcing plate 13 is connected to the mounting plate 9, and the other end of the reinforcing plate 13 is connected to the two fixing plates 12.
[0033] During specific implementation, the fixing plate 12 is fixed on the scissor lift 4 to provide installation positions for the mounting plate 9 and the reinforcing plate 13. The reinforcing plate 13 connects the mounting plate 9 and the fixing plate 12, enhancing the stability of the mounting plate 9.
[0034] Refer to Figures 1 - 5 , a sliding plate 14 is connected to the connecting plate 10, and the sliding plate 14 is slidably connected to the fixing plate 12.
[0035] During specific implementation, the sliding plate 14 on the connecting plate 10 slides on the fixing plate 12 to assist the sliding of the connecting plate 10 on the mounting plate 9, making the movement of the front baffle 7 more stable.
[0036] Refer to Figures 1 - 5 , a servo motor 16 is connected to one side of the mounting base 1, and the driving end of the servo motor 16 is connected to one end of the flywheel roller 3 through a coupling for driving the flywheel roller 3 to rotate.
[0037] During specific implementation, after the servo motor 16 is started, its driving end drives the flywheel roller 3 to rotate through the coupling, providing power for the flywheel roller 3, enabling the flywheel roller 3 to rotate at a set speed and direction.
[0038] Embodiment 2
[0039] The working process of a thin plate automatic stacking device includes the following steps:
[0040] The slit thin plates are placed on the conveyor belt and are conveyed forward as the conveyor belt runs. When the thin plate reaches the discharge end of the transport member 2, since the diameter of the flywheel roller 3 is larger than that of the passive roller, the running trajectory of the conveyor belt changes when passing through the flywheel roller 3, driving the thin plate to run in a parabola, and then the thin plate falls into the material collection frame at the top of the scissor lift 4.
[0041] When the thin plate falls into the material collection frame, it will first hit the front baffle 7. The front baffle 7 is connected to the connecting plate 10 through a plurality of return springs 8. The return springs 8 undergo elastic deformation under the impact force, absorbing and buffering the kinetic energy of the thin plate impact. At the same time, the inclined cylinder 11 is subjected to the reaction force generated by the thin plate hitting the front baffle 7. One end of the cylinder 11 is connected to the connecting plate 10, and the other end is connected to the mounting plate 9. Moreover, the connecting plate 10 can slide on the mounting plate 9. The cylinder 11 performs telescopic actions according to the reaction force, pushing the connecting plate 10 to slide on the mounting plate 9, and then driving the front baffle 7 to move backward, pushing the buffered thin plate backward against the rear baffle 6 to complete a stacking and positioning of the thin plate.
[0042] Working principle: The cut thin plates are placed on the conveyor belt and are transported forward as the conveyor belt runs. When the thin plate reaches the discharge end of the transport member 2, since the diameter of the flywheel roller 3 is larger than that of the passive roller, the running trajectory of the conveyor belt changes when passing through the flywheel roller 3, driving the thin plate to move in a parabola, and then the thin plate falls into the material collection frame at the top of the scissor lift 4.
[0043] When the thin plate falls into the material collection frame, it will first hit the front baffle 7. The front baffle 7 is connected to the connecting plate 10 through a plurality of return springs 8. The return springs 8 undergo elastic deformation under the impact force, absorbing and buffering the kinetic energy of the thin plate impact. At the same time, the inclined cylinder 11 is subjected to the reaction force generated by the thin plate hitting the front baffle 7. One end of the cylinder 11 is connected to the connecting plate 10, and the other end is connected to the mounting plate 9. Moreover, the connecting plate 10 can slide on the mounting plate 9. The cylinder 11 performs telescopic actions according to the reaction force, pushing the connecting plate 10 to slide on the mounting plate 9, and then driving the front baffle 7 to move backward, pushing the buffered thin plate backward against the rear baffle 6 to complete a stacking and positioning of the thin plate.
[0044] During the stacking process, the photoelectric detection member 15 on one side of the side plate 5 of the material collection frame real-time detects the stacking height of the thin plates in the frame. If the stacking height reaches a certain level, the photoelectric detection member 15 will send out a signal to control the scissor lift 4 to descend a certain height for continuous stacking operations.
