Description

Technical Field

[0001] The present invention relates to the field of cardboard transportation equipment, and specifically to a cardboard transportation equipment with an anti-collision function. Background Art

[0002] Cardboard transportation equipment is a special equipment used for handling, transporting, stacking or loading and unloading cardboard in the processes of cardboard production, processing, warehousing or logistics. The application scenarios of such equipment are extensive and can cover the full-process transportation requirements from raw materials to finished products.

[0003] When the existing cardboard transportation equipment needs to handle the stacked cardboard piece by piece, generally, manual handling is used to handle the cardboard, which can ensure that the edges of the cardboard are not knocked or collided as much as possible. However, the efficiency of manual handling is low. There are also some existing technologies that use rollers pressed on the top surface of the cardboard stack to send out the topmost cardboard through the rotation of the rollers.

[0004] In view of the above related technologies, during the process of handling cardboard by the cardboard handling equipment in the prior art, since the topmost cardboard has a certain initial velocity when leaving the cardboard stack, whether the cardboard falls on the subsequent folding machine or the conveyor line, the corners of the cardboard are prone to varying degrees of knocking and collision, which not only affects the aesthetic degree of the cardboard, but also has a certain impact on the performance of the cardboard. In summary, the existing cardboard handling equipment is not easy to stably handle the topmost cardboard of the cardboard stack. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a cardboard transportation equipment with an anti-collision function to solve the technical problem that the existing cardboard handling equipment is not easy to stably handle the topmost cardboard of the cardboard stack.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A cardboard transportation equipment with an anti-collision function, including a box body. On both sides inside the box body, there are installed lifting platforms that can be vertically lifted. On one side of the lifting platforms close to each other, there are slidingly connected moving platforms. There is also an installation plate, which is connected between the moving platforms and the bottom surface of the installation plate is flush with the bottom surface of the moving platforms. At the end of the moving platform, there is installed a pushing block for pushing the topmost cardboard of the cardboard stack. Between the installation plate and the moving platform, there is installed a clamping mechanism for clamping the cardboard after being pushed.

[0007] By adopting the above technical solution, the layer-by-layer handling of the cardboard on the cardboard stack can be realized as the clamping structure moves in the reverse direction, and the cardboard will not be impacted during the handling process, effectively improving the stability of the cardboard handling equipment when handling cardboard.

[0008] The present invention is further configured such that one end of the mounting plate is fixedly installed with a telescopic rod. The telescopic rod includes a fixed section fixedly connected to the mounting plate and a telescopic section slidably connected within the fixed section. The end of the telescopic section of the telescopic rod is fixedly connected with a moving plate. The bottom end of the moving plate is fixedly connected with a supporting plate parallel to the mounting plate. The distance between the top surface of the supporting plate and the bottom surface of the mounting plate is greater than the thickness of the cardboard.

[0009] Preferably, the telescopic rod is used to control the expansion and contraction of the clamping mechanism.

[0010] The present invention is further configured such that a rotating shaft is rotatably connected between the moving platforms at the end far from the telescopic rod. The rotating shaft is fixedly connected with a rotating plate. The end of the rotating plate far from the rotating shaft is fixedly connected with an inserting plate capable of being inserted between the topmost cardboard and the second topmost cardboard in the cardboard stack.

[0011] Preferably, the rotation of the rotating plate can deform the inserting plate and insert it between two layers of cardboard.

[0012] The present invention is further configured such that a sliding bar is slidably connected to the moving platform along the length direction. One end of the sliding bar is fixedly connected with the moving plate, and a rack is provided at the other end in the direction towards the rotating shaft. A first gear for meshing with a second gear is connected to the rotating shaft through a damping structure. The second gear is rotatably connected to the moving platform and meshes with both the first gear and the rack simultaneously.

[0013] Preferably, while the moving plate moves, the rotating plate rotates, so that the inserting plate and the supporting plate cooperate together to further improve the stability during the transportation of the cardboard.

[0014] The present invention is further configured such that the pushing block is slidably connected to the end of the moving platform in the vertical direction. An adjusting screw for controlling the elongation amount of the pushing block is connected to the end of the moving platform. The bottom end of the adjusting screw contacts the top end of the pushing block. A spring is provided between the pushing block and the moving platform in the direction away from the adjusting screw.

[0015] Preferably, the elongation amount of the pushing block is controlled by rotating the adjusting screw.

[0016] The present invention is further configured such that a blocking bar for restricting the rotation of the rotating plate is fixedly connected between the moving platforms. When the rotating plate is restricted by the blocking bar, it is in a state orthogonal to the mounting plate. When the rotating plate is restricted by the mounting plate and cannot rotate, the top surface of the inserting plate and the top surface of the supporting plate are in the same horizontal plane.

[0017] Preferably, the top surfaces of the supporting plate and the inserting plate can support the cardboard, while the opposite surfaces of the rotating plate, the pushing block and the moving plate clamp the side surfaces of the cardboard.

[0018] The present invention is further configured such that the lifting table is installed in the box body through a vertical lifting mechanism, and first sliding grooves are arranged oppositely. A first screw rod is arranged along the length direction in the first sliding grooves. A moving block that can slide in the first sliding grooves is threadedly connected to the first screw rod. The moving table is slidably connected to one side of the lifting table along its own length direction, and a corresponding second sliding groove is arranged towards the first sliding groove. A second screw rod is also arranged along the length direction in the second sliding groove. The moving block is simultaneously threadedly connected to the second screw rod and can slide in the second sliding groove.

[0019] Preferably, by respectively controlling the rotation of the first screw rod and the second screw rod, the cardboard on the cardboard stack is transferred and carried layer by layer.

[0020] The present invention is further configured such that a bearing frame is fixedly installed at one end of the box body, and a bearing plate for bearing the cardboard stack is slidably connected to the bearing frame along the vertical direction.

[0021] Preferably, the cardboard stack is borne by the bearing plate.

[0022] The present invention is further configured such that a plurality of guide columns vertically passing through the bearing frame are fixedly connected to the bottom surface of the bearing plate. Compression springs are arranged between the bearing plate and the bearing frame along the axis of each guide column. A pressing switch is installed on the bearing frame towards the bearing plate. When the moving table and the mounting plate do not contact the top layer of the cardboard stack, the pressing switch will not be pressed down.

[0023] Preferably, it effectively prevents the cardboard stack from being overly pressed down.

[0024] The present invention is further configured such that rollers with parallel axes are rotatably connected to the mounting plate at intervals. The axes of the rollers are all orthogonal to the moving direction of the moving table, and the bottom surface can contact the cardboard before the mounting plate.

[0025] Preferably, the rollers can effectively reduce the friction between the mounting plate and the surface of the cardboard during the movement of the moving table, so that the pushing block can contact the edge of the cardboard faster.

[0026] In summary, the present invention mainly has the following beneficial effects:

[0027] 1. By installing a clamping mechanism capable of horizontal movement on the box body, the present invention pushes the cardboard on the top layer of the cardboard stack to slide while moving, and then stably clamps the top layer of cardboard during the reverse movement. As the clamping structure moves in the reverse direction, the cardboard on the cardboard stack can be transferred layer by layer, and the cardboard will not be impacted during the transfer process, effectively improving the stability of the cardboard handling equipment when handling cardboard.

[0028] 2. In the present invention, a carrier is installed at one end of the box body, and the cardboard stack is placed on the carrier plate that is vertically slidably connected to the carrier. While the clamping mechanism presses down, the pressure switch between the carrier and the carrier plate can provide a clamping instruction for the clamping mechanism, avoiding deformation of the cardboard stack caused by excessive pressing of the clamping mechanism.

[0029] 3. In the present invention, the moving block is simultaneously threadedly connected to the mutually parallel screw rods in two different chutes. By respectively controlling the forward and reverse rotations of the two screw rods, the moving platform extends out towards both sides of the box body, so as to be able to grab the cardboard on the top layer of the cardboard stack from one side of the box body and smoothly send the grabbed cardboard to the other side of the box body for release.

[0030] 4. In the present invention, a push block capable of vertically adjusting the extension amount is provided at the tail end of the moving platform. By rotating the adjusting screw rod, the length of the push block extending beyond the bottom surface of the mounting plate can be conveniently controlled, thereby adapting to cardboard of different thicknesses and ensuring that each time only one piece of cardboard on the top layer of the cardboard stack can be stably pushed.

[0042] 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. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0043] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0044] The first embodiment:

[0045] A cardboard transportation device with an anti-collision function, please refer to Figures 1-9 , which includes a box body 1. On both sides inside the box body 1, there is a lifting platform 2 that can be vertically lifted. Specifically, in this embodiment, the lifting platform 2 is specifically controlled to lift by a vertically arranged screw. On both sides of the lifting platform 2, there are also vertical guide rods to ensure the stable lifting of the lifting platform 2. The lifting principle of the lifting platform 2 has been well documented in the prior art, and the lifting principle will not be elaborated here. On the sides of the lifting platform 2 that are close to each other, there are moving platforms 3 that are slidably connected.

[0046] It also includes a mounting plate 5. The mounting plate 5 is connected between the moving platforms 3, and the bottom surface is flush with the bottom surface of the moving platforms 3. At the end of the moving platforms 3, there is a pushing block 13 for pushing the topmost cardboard of the cardboard stack. A clamping mechanism for clamping the cardboard after being pushed is installed between the mounting plate 5 and the moving platforms 3. The topmost cardboard body 19 is clamped by the clamping mechanism to stably transport the topmost cardboard of the cardboard stack.

[0047] In the above embodiment, specifically, please refer to Figures 2-3 , Figure 9 , one end of the mounting plate 5 is fixedly installed with a telescopic rod 6. Specifically, the telescopic rod 6 is specifically an electric push rod in this embodiment. In other unpublicized embodiments, the telescopic rod 6 can also be a hydraulic rod or other telescopic structures.

[0048] Further, the telescopic rod 6 includes a fixed section fixedly connected to the mounting plate 5 and a telescopic section slidably connected within the fixed section. A moving plate 7 is fixedly connected to the end of the telescopic section of the telescopic rod 6. A support plate 701 parallel to the mounting plate 5 is fixedly connected to the bottom end of the moving plate 7. The distance between the top surface of the support plate 701 and the bottom surface of the mounting plate 5 is greater than the thickness of the cardboard, preventing the support plate 701 from directly hitting the edge of the uppermost cardboard body 19 during the movement towards the cardboard stack, and using the telescopic rod 6 to control the expansion and contraction of the clamping mechanism.

[0049] In the above embodiment, specifically, please refer to Figures 2-3 、 Figure 8 , a carrier frame 14 is fixedly installed at one end of the box body 1. A carrier plate 15 for carrying the cardboard stack is slidably connected to the carrier frame 14 in the vertical direction, and the cardboard stack is carried by the carrier plate 15.

[0050] In the above embodiment, specifically, please refer to Figures 2-3 、 Figures 6-7 、 Figure 9 , the lifting platform 2 is installed in the box body 1 through a vertical lifting mechanism, and is provided with first sliding grooves 201 facing each other. A first screw rod 202 is arranged along the length direction in the first sliding grooves 201. A moving block 4 that can slide in the first sliding grooves 201 is threadedly connected to the first screw rod 202. The moving platform 3 is slidably connected to one side of the lifting platform 2 along its own length direction, and a corresponding second sliding groove 301 is arranged facing the first sliding grooves 201. A second screw rod 302 is also arranged along the length direction in the second sliding groove 301. The moving block 4 is simultaneously threadedly connected to the second screw rod 302 and can slide in the second sliding groove 301. Specifically, motors for driving the first screw rod 202 and the second screw rod 302 to rotate are respectively installed in the lifting platform 2 and the moving platform 3.

[0051] Specifically, when the moving platform 3 needs to extend towards the end of the box body 1 where the carrier frame 14 is arranged, the moving block 4 moves towards the end where the carrier frame 14 is located in the first sliding groove 201, and moves away from the end where the carrier frame 14 is located in the second sliding groove 301, so as to realize the moving platform 3 extending towards the end of the carrier frame 14 and protruding from the box body 1. On the contrary, when wanting the moving platform 3 to extend away from the end of the box body 1 where the carrier frame 14 is arranged, it is the same principle. By respectively controlling the rotation of the first screw rod 202 and the second screw rod 302, the cardboard on the cardboard stack is transferred and carried layer by layer, and the cardboard is transported from one end of the box body 1 to the other end layer by layer.

[0052] The second embodiment:

[0053] A cardboard transportation device with an anti-collision function, please refer to Figures 1-9, based on the first embodiment, the difference from the first embodiment is that a rotating shaft 9 is rotatably connected between the mobile stations 3 at the end far from the telescopic rod 6. The rotating shaft 9 is fixedly connected with a rotating plate 10. One end of the rotating plate 10 far from the rotating shaft 9 is fixedly connected with an inserting plate 11 that can be inserted between the top cardboard and the second top cardboard of the cardboard stack. The rotation of the rotating plate 10 can deform the inserting plate 11 and insert it between two layers of cardboard. Specifically, in this embodiment, the inserting plate 11 is a metal thin plate with a certain flexibility, and 304 stainless steel with a thickness of 2 mm can be specifically used. It can deform and insert between two layers of cardboard during the rotation of the rotating plate 10, and can also play a role in supporting the cardboard when the lifting platform 2 rises.

[0054] In the above embodiment, specifically, please refer to Figures 2-3 , Figures 6-7 Figure 9 , a sliding bar 8 is slidably connected to the mobile station 3 along the length direction. One end of the sliding bar 8 is fixedly connected with the moving plate 7, and a rack 801 is arranged at the other end in the direction of the rotating shaft 9. A first gear 901 for meshing with the second gear 902 is connected to the rotating shaft 9 through a damping structure. The second gear 902 is rotatably connected to the mobile station 3 and meshes with both the first gear 901 and the rack 801 at the same time. When the moving plate 7 moves, the rotating plate 10 is rotated, so that the inserting plate 11 and the supporting plate 701 cooperate together to further improve the stability during the transportation of the cardboard.

[0055] Specifically, the damping mechanism between the rotating shaft 9 and the first gear 901 enables the first gear 901 to drive the rotating shaft 9 to rotate when the first gear 901 rotates, but when the rotating plate 10 is limited, the rotating shaft 9 cannot rotate. The first gear 901 can rotate relative to the rotating shaft 9 when receiving sufficient torque, thereby avoiding the sliding bar 8 from being unable to slide due to the rotation plate 10 being limited.

[0056] Furthermore, the second gear 902 plays a role in reversing. When the moving plate 7 moves towards the mounting plate 5, it can ensure that the rotating plate 10 can be turned downward, and when the moving plate 7 moves in the reverse direction and resets, it can also turn the rotating plate 10 over and lift it to reset.

[0057] In the above embodiment, specifically, please refer to Figures 8-9, a plurality of guide columns 16 vertically passing through the carrier frame 14 are fixedly connected to the bottom surface of the carrier plate 15. Compression springs are provided between the carrier plate 15 and the carrier frame 14 along the axis of each guide column 16. A push switch 17 is installed on the carrier frame 14 in the direction towards the carrier plate 15. Specifically, when the paperboard stack is placed on the top surface of the carrier plate 15, the push switch 17 is not pressed. When the push switch 17 is pressed, the lifting table 2 will stop moving downward. Specifically, the specific principle of using the push switch 17 to control the lifting table 2 to stop moving downward is not described in detail in this application. When the moving table 3 and the mounting plate 5 do not contact the top layer of the paperboard stack, the push switch 17 will not be pressed, effectively preventing the paperboard stack from being over-pressed.

[0058] The third embodiment:

[0059] A paperboard transportation device with an anti-collision function, please refer to Figures 1-9 , on the basis of the second embodiment, the difference from the second embodiment is that the push block 13 is slidably connected to the end of the moving table 3 in the vertical direction. An adjusting screw 12 for controlling the elongation of the push block 13 is connected to the end of the moving table 3. The bottom end of the adjusting screw 12 contacts the top end of the push block 13. A spring is provided between the push block 13 and the moving table 3 in the direction away from the adjusting screw 12. By rotating the adjusting screw 12, the elongation of the push block 13 is controlled, thereby adapting to paperboard bodies 19 of different thicknesses and preventing the push block 13 from simultaneously pushing two paperboard bodies 19.

[0060] In the above embodiment, specifically, please refer to Figures 7-9 , a blocking bar 303 for restricting the rotation of the rotating plate 10 is fixedly connected between the moving tables 3. When the rotating plate 10 is restricted by the blocking bar 303, it is in a state orthogonal to the mounting plate 5. When the rotating plate 10 is restricted by the mounting plate 5 and cannot rotate, the top surface of the inserting plate 11 is on the same horizontal plane as the top surface of the supporting plate 701. The top surfaces of the supporting plate 701 and the inserting plate 11 can support the paperboard, while the opposite surfaces of the rotating plate 10, the push block 13 and the moving plate 7 clamp the side surface of the paperboard.

[0061] Furthermore, roller columns 18 with parallel axes are rotatably connected to the mounting plate 5 at intervals. The axes of the roller columns 18 are all orthogonal to the moving direction of the moving table 3, and the bottom surface can contact the paperboard prior to the mounting plate 5. The roller columns 18 can effectively reduce the friction between the mounting plate 5 and the paperboard surface during the movement of the moving table 3, thereby enabling the push block 13 to contact the edge of the paperboard faster and effectively preventing the situation where the mounting plate 5 pushes the paperboard body 19 to move due to the friction between the mounting plate 5 and the paperboard body 19, resulting in the push block 13 being unable to contact the edge of the paperboard body 19.

[0062] When the present invention specifically transports the paperboards on the paperboard stack layer by layer:

[0063] While the height of the lifting table 2 decreases, the moving table 3 extends towards the end of the box body 1 provided with the bearing plate 15. Before the pushing block 13 touches the cardboard, the moving table 3 and the mounting plate 5 have pressed down the stack of cardboard. When the height of the bearing plate 15 decreases and presses down the pressing switch 17, at this time, the lifting table 2 stops descending, but the moving table 3 continues to extend. The pushing block 13 touches and pushes the cardboard body 19 at the top layer of the stack of cardboard to slide, so that one end of the cardboard body 19 close to the moving plate 7 extends away from the stack of cardboard;

[0064] Then, the telescopic section of the telescopic rod 6 contracts, so that the supporting plate 701 moves towards the stack of cardboard but does not touch the cardboard. The supporting plate 701 moves to the lower end of the extended part of the cardboard body 19. At the same time, due to the movement of the moving plate 7, the sliding strip 8 slides, and the rack 801 drives the second gear 902 to rotate, which in turn drives the first gear 901 to rotate, so that the rotating plate 10 flips downwards. After the inserting plate 11 touches the surface of the cardboard body 19, it deforms and bends and inserts between the topmost cardboard body 19 and the second topmost cardboard body 19;

[0065] The lifting table 2 rises to stably lift the topmost cardboard of the stack of cardboard. After the moving table 3 extends in the reverse direction and transports the cardboard to the other end of the box body 1, the telescopic section of the telescopic rod 6 extends. While the rotating plate 10 rotates reversely and resets, the inserting plate 11 moves away from the mounting plate 5, and the cardboard can be released.

[0066] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations to the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
