Description

Technical Field

[0001] This invention relates to the field of cardboard box conveying technology, and in particular to a corrugated cardboard box stacking and conveying equipment and its conveying method. Background Technology

[0002] Cardboard boxes are commonly used as wrapping materials for goods or as protective outer layers for items. As an indispensable part of modern logistics, they bear the important responsibilities of containing, protecting, and aesthetically pleasing products. After a series of production processes, cardboard boxes often need to be stacked neatly to facilitate handling and storage.

[0003] For multiple single cartons, the existing carton stacking method is mostly to stack them layer by layer using mechanical equipment. The advantages of mechanical equipment are low cost and simple operation. However, when stacking in this way, the cartons are not stable. After stacking, they can not only move, but also be affected by external forces, causing misalignment and affecting subsequent packaging. Moreover, as the height of the carton stack increases, its stability will further decrease, which is quite inconvenient. Summary of the Invention

[0048] Preferably, a controller is fixedly installed on the outer wall of the conveyor, and the controller is used to control the start and stop of the conveyor, the first cylinder, the second cylinder and the motor.

[0049] The present invention also provides a conveying method for a corrugated cardboard box stacking and conveying device, comprising the following specific steps:

[0050] Step 1: Carton gripping and transfer. The controller starts the conveyor, which intermittently transports a single corrugated carton to the designated position. The first cylinder in the pushing mechanism drives the pushing frame to move above the carton. The air pump works to create negative pressure in the suction cup and pick up the carton. Then the first cylinder moves the carton horizontally into the stacking box and places it on the support plate.

[0051] Step 2: Carton release and pre-alignment. The second cylinder drives the moving plate and alignment plate to move down as a whole. At the same time, the extrusion frame fixed to the top of the pressing plate moves down as well. It extrudes the second extrusion block through the second extrusion groove on its inner side, causing the extrusion plate to move horizontally. This forces the air in the second air groove into the first air groove of the pressing plate, driving the first piston and rack. The gear drives the pressing plate to flip from horizontal to vertical to make room. At this time, the vertical pressing plate limits the downward movement of the first extrusion rod, so that the support plate can be contracted through the first extrusion block. The carton is released and falls at a fixed height. As it continues to move down, the inclined surface of the alignment plate assists in guiding and aligning the carton stack.

[0052] Step 3: Stacking and Compacting and State Reset. After the cartons are stacked on the stack, the second cylinder drives the moving plate and the squeezing frame to rise and reset. Under the action of the second compression spring, the squeezing plate and the second piston of the adjusting component are reset, the air pressure is drawn back, and the first piston and the rack are reset. Then, the pressing plate is driven to flip back from the vertical state to the horizontal state. At the same time, the motor of the pressing adjustment mechanism is started, driving the screw to rotate, so that the lifting plate moves along the slide rod to move the fixed frame and the pressing plate that has been restored to the horizontal position by a distance of one carton thickness, so that the pressing plate is pressed firmly on the top carton.

[0053] Step 4: Repeat steps 1 to 3 until the preset number of carton layers are stacked automatically to form a carton stack, which is ready for subsequent packaging or transportation.

[0054] The technical effects and advantages of this invention are as follows:

[0055] (1) The present invention utilizes a combination of a stacking box, a pushing mechanism, a conveying alignment mechanism and a pressing adjustment mechanism. The pushing mechanism can intermittently convey the carton into the stacking box, and the conveying alignment mechanism will align and stack the carton layer by layer. The pressing adjustment mechanism will change the pressing height according to the stacking height, so that after each alignment and stacking, the carton can be pressed on the top carton, avoiding interlayer slippage and offset, improving the overall stability of the stack and the ability to resist external interference. Even if the stacking height increases, it can ensure that each layer is accurately aligned, effectively preventing tipping, making the subsequent packaging process smoother and more efficient, and easy to use.

[0056] (2) The present invention utilizes a combination of a first cylinder, a pusher, a suction cup and an air pump. The air pump continuously extracts air from the air passage, which creates negative pressure in the suction cup. This allows the cartons that are intermittently conveyed by the conveyor to be picked up and transported to the inside of the stacking box by the first cylinder and placed on the support plate. This repeated picking and handling achieves stable gripping and precise transfer of the cartons, ensuring that the cartons are uniform in posture and accurate in position during the handling process. This lays a reliable foundation for subsequent layer-by-layer alignment and stacking, and improves the continuity and stability of automated stacking.

[0057] (3) The present invention utilizes the cooperative arrangement of the conveying alignment mechanism and the pressing adjustment mechanism, so that each time the conveying alignment mechanism puts down the cardboard, it uses air pressure to make the pressing plate of the cardboard flip from horizontal to vertical. At the same time, when the cardboard is put down, the first pressing rod will pull the first pressing block because of the vertical pressing plate, so that the support plate will contract when it is a fixed distance away from the cardboard stack, causing the cardboard to fall. When the alignment plate continues to fall, the inclined stack of cardboard is used for auxiliary alignment, ensuring that each layer can accurately fall into the designated position. After resetting, the pressing plate is flipped back to horizontal state by air pressure, and the height adjustment of the motor makes the pressing plate continue to press the top cardboard, improving the neatness of the stack and the stability of the overall structure.

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] This invention provides, for example Figure 1-8The corrugated cardboard box stacking and conveying equipment shown includes a base 1, a conveyor 2, a stacking box 3, a pushing mechanism 4, a conveying alignment mechanism 5, and a pressing adjustment mechanism 6. The conveyor 2 is fixedly installed on the top of the base 1; the stacking box 3 is fixedly connected to the top of the base 1, and the stacking box 3 is provided with a pushing mechanism 4 for transferring the cardboard boxes conveyed by the conveyor 2 into the interior of the stacking box 3. The stacking box 3 is provided with a conveying alignment mechanism 5 and a pressing adjustment mechanism 6. The pushing mechanism 4 can intermittently convey the cardboard boxes into the interior of the stacking box 3, and the conveying alignment mechanism 5 and pressing adjustment mechanism 6 can be used to adjust the cardboard boxes. Mechanism 5 aligns and stacks the boxes layer by layer, and then the pressing and adjusting mechanism 6 changes the pressing height according to the stacking height, so that after each alignment and stacking, the box can be pressed onto the top layer of cardboard, avoiding slippage and displacement between layers, improving the overall stability of the stack and the ability to resist external interference. Even if the stacking height increases, it can ensure that each layer is accurately aligned, effectively preventing tipping, and making the subsequent packaging process smoother and more efficient. In addition, the back of the stacking box 3 is equipped with a door for easy opening and closing to retrieve the stacked cardboard boxes inside. At the same time, there are two slots at the bottom of the inner wall of the stacking box 3 for easy removal of the cardboard box stack, making it convenient to use.

[0070] Specifically, the pushing mechanism 4 includes a first cylinder 41, a pushing frame 42, a suction cup 43, and an air pump 44. The first cylinder 41 is symmetrically fixedly installed on the outer wall of the stacking box 3. The output end of the first cylinder 41 is connected to the pushing frame 42, and the cross-section of the pushing frame 42 is L-shaped. The suction cups 43 are fixedly installed at equal intervals at the bottom end of the pushing frame 42, and the pushing frame 42 has an air passage inside. The air pump 44 is fixedly installed at the top of the pushing frame 42 and is used to draw out the air in the air passage to generate negative pressure in the suction cups 43. By continuously drawing out the air in the air passage using the air pump 44, the suction cups 43 can generate negative pressure, thereby picking up the cartons intermittently conveyed by the conveyor 2 and conveying them to the inside of the stacking box 3 through the first cylinder 41, and placing them on the support plate 55. This repeated picking and handling realizes stable gripping and precise transfer of cartons, ensuring that the cartons have a uniform posture and accurate position during the handling process, laying a reliable foundation for subsequent layer-by-layer alignment and stacking, and improving the continuity and stability of automated stacking.

[0071] Specifically, the conveying and alignment mechanism 5 includes a second cylinder 51, a moving plate 52, and a pressing frame 53. The second cylinder 51 is fixedly installed on the top of the stacking box 3. The moving plate 52 is located inside the stacking box 3, and the output end of the second cylinder 51 is connected to the moving plate 52 in a transmission manner. The pressing frame 53 is symmetrically fixedly connected to the top of the moving plate 52. After the carton is placed on the support plate 55, the second cylinder 51 can drive the moving plate 52 to move downward, thereby conveying the carton downward for placement.

[0072] Furthermore, the conveying alignment mechanism 5 also includes an alignment plate 54, a support plate 55, a first extrusion rod 56, a first extrusion block 57, and a first compression spring 58. The alignment plate 54 is fixedly connected to both sides of the moving plate 52. An inclined surface is provided on each opposite side of the alignment plate 54. The inclined surface facilitates alignment of the top cartons while the plate is moving downwards, which is convenient for subsequent packaging. A support groove is provided inside the alignment plate 54, and the support plate 55 is slidably inserted into the inner cavity of the support groove. The first extrusion rod 56 is slidably inserted into the inner cavity of the support plate 55, and the cross-section of the first extrusion rod 56 is L-shaped. The first extrusion block 57 is fixedly connected to both sides of the first extrusion rod 56, and a first extrusion groove matching the first extrusion block 57 is provided on both sides of the inner wall of the support plate 55. The first compression spring 58 is disposed inside the support groove. One end of the first compression spring 58 is fixedly connected to the top of the inner wall of the support groove, and the other end of the first compression spring 58 is fixedly connected to the first extrusion rod 56. Spring 58 consistently provides a stable downward elastic force to the first extrusion rod 56, allowing the first extrusion block 57 to press the first extrusion groove, enabling the support plate 55 to extend stably and support the cardboard boxes delivered by the pushing mechanism 4. Each time cardboard is lowered, the pressing adjustment mechanism 6 uses air pressure to flip the pressing plate 65 from horizontal to vertical. Simultaneously, when the cardboard is lowered, the first extrusion rod 56 is limited by the vertical pressing plate 65, pulling the first extrusion block 57. This causes the support plate 55 to retract at a fixed distance from the cardboard stack, allowing the cardboard to fall. As the alignment plate 54 continues to fall, the inclined stack of cardboard is used for auxiliary alignment, ensuring that each layer falls precisely in the designated position. After resetting, air pressure is used to flip the pressing plate 65 back to a horizontal position, and with the height adjustment of the motor 619, the pressing plate 65 continues to press the top layer of cardboard, improving the neatness of the stack and the stability of the overall structure.

[0073] Specifically, the pressing and adjusting mechanism 6 includes a screw 61, a slide rod 62, a lifting plate 63, a pressing assembly, and an adjusting assembly. Both sides of the stacking box 3 have through slots. The end of the screw 61 is rotatably inserted into the inner wall of the through slot. A motor 619 is symmetrically fixedly installed inside the stacking box 3, and the output end of the motor 619 is connected to the screw 61 for transmission. The slide rod 62 is symmetrically arranged on both sides of the screw 61, and its end is fixedly connected to the inner wall of the through slot. The lifting plate 63 is slidably inserted into the slide rod 62, and the lifting plate 63 and the screw 61 form a threaded connection. The lever drive, via motor 619, enables screw 61 to rotate in both directions, allowing lifting plate 63 to move vertically back and forth under the limit of slide rod 62. This allows for adjustment of the pressing component's height, facilitating changes in pressing height with each layer of cartons placed. As the stacking height increases, the pressing point remains at the top layer, effectively compacting the cartons already stacked below. The pressing component is mounted on lifting plate 63 for pressing and fixing the cartons. The adjusting component is mounted on stacking box 3 for adjusting the state of the pressing component.

[0074] Furthermore, the pressing assembly includes a fixed frame 64, a pressing plate 65, and a limiting block 66. The fixed frame 64 is fixedly connected to one side of the lifting plate 63. The pressing plate 65 is rotatably disposed inside the fixed frame 64 via a rotating shaft and is used to press the carton. The outer wall of the fixed frame 64 is provided with an arc-shaped groove that slides with the limiting block 66. Under the limitation of the arc-shaped groove, the pressing plate 65 can only rotate 90° forward and backward, so that it can switch between horizontal and vertical states, which is convenient for lowering and pressing the carton.

[0075] Furthermore, the adjustment assembly includes a first piston 67, a rack 68, a gear 69, a second piston 610, a slider 611, a connecting rod 612, a second compression spring 613, a pressing plate 614, a second pressing block 615, a ball bearing 616, a synchronizing tube 617, and a connecting tube 618. The pressing plate 65 has symmetrically formed first air grooves inside, and the first piston 67 is slidably inserted into the inner cavity of the first air groove. The rack 68 is fixedly connected to the first piston 67. The bottom end of the pressing plate 65 has equidistant grooves, and the gear 69 is located inside the grooves. The gear 69 is fixedly inserted into the rotating shaft, and the rack 68 is meshed with the gear 69. The stacking box 3 has symmetrically arranged second air grooves inside, and the second piston 610 is slidably inserted into the inner cavity of the second air groove; a sliding groove is provided at the top of the inner wall of the stacking box 3, and the slider 611 is slidably inserted into the inner cavity of the sliding groove; one end of the connecting rod 612 is fixedly connected to the slider 611, and the other end of the connecting rod 612 is fixedly connected to the inner wall of the sliding groove; one end of the second compression spring 613 is fixedly connected to the slider 611, and the other end of the second compression spring 613 is fixedly connected to the inner wall of the sliding groove; the extrusion plate 614 is fixedly connected to the bottom end of the slider 611, and one end of the extrusion plate 614 is slidably inserted into the inner cavity of the extrusion frame 53; the second extrusion block 615 is fixedly connected to both sides of the extrusion plate 614, and both sides of the inner wall of the extrusion frame 53 are provided with second extrusion grooves that cooperate with the sliding of the second extrusion block 615, and the cross-section of the second extrusion groove is as shown in Figure 1. Figure 5As shown, it can guide the second extrusion block 615 through vertical displacement, thereby realizing the horizontal reciprocating movement of the extrusion plate 614; the ball bearing 616 is embedded in the end of the extrusion plate 614. The ball bearing 616 ensures that after the second extrusion block 615 disengages from the second extrusion groove, it can remain close to the output end of the second cylinder 51 under the elastic force of the second compression spring 613, keeping the position of the second extrusion block 615 stable, so that it can re-enter the second extrusion groove during subsequent reset; the synchronous tube 617 is fixedly connected to the outer wall of the lifting plate 63. The synchronous tube 617 is hollow inside, which facilitates the connection between the two A first air groove is provided, allowing the first air groove to be connected to the second air groove via a connecting pipe 618, facilitating the adjustment of the position of the pressing plate 65. One end of the connecting pipe 618 is fixedly inserted into the synchronization pipe 617, and the other end is fixedly inserted into the second air groove. The connecting pipe 618 is made of flexible tubing and is used to connect the first and second air grooves. The second compression spring 613 always provides a stable elastic force to the extrusion plate 614 through the slider 611. When the extrusion frame 53 moves downward, the extrusion plate 614 can be moved horizontally by the second extrusion groove, thereby... The second compression spring 613 can be used to drive the second piston 610 connected to the connecting rod 612, causing the air inside the second air groove to be compressed and transported to the inside of the two first air grooves through the connecting pipe 618 and the synchronization pipe 617. This allows the first piston 67 to drive the rack 68 to move, causing the gear 69 to drive the pressing plate 65 to flip from a horizontal state to a vertical state. When the second cylinder 51 drives the pressing frame 53 to reset, the second pressing groove can be used to press the second pressing block 615, thereby causing the pressing plate 614 to drive the slider 611 to move, and causing the second compression spring to... When 613 is in a compressed state, it can pull the second piston 610 to reset, causing the air pressure to be drawn back into the second air groove. At this time, the first piston 67 will be displaced and reset, thereby resetting the pressing plate 65 from the vertical state to the horizontal state. This realizes the placement of the carton when opening and the pressing of the carton when closing, achieving precise synchronization between mechanical action and pneumatic control. By driving the rack 68 and gear 69 with air pressure, the horizontal displacement is efficiently converted into a flipping torque. It is not only compact and responsive, but also avoids rigid impact, protects the cardboard surface from damage, and ensures the smoothness and accuracy of each alignment action.

[0076] Furthermore, a controller 7 is fixedly installed on the outer wall of the conveyor 2. The controller 7 is used to control the start and stop of the conveyor 2, the first cylinder 41, the second cylinder 51 and the motor 619.

[0077] The conveying method of this invention:

[0078] Step 1: Carton gripping and transfer. The controller 7 starts the conveyor 2, which intermittently transports a single corrugated carton to the designated position. The first cylinder 41 in the pushing mechanism 4 drives the pushing frame 42 to move above the carton. The air pump 44 works to generate negative pressure in the suction cup 43 and suck up the carton. Then the first cylinder 41 moves the carton horizontally into the stacking box 3 and places it on the support plate 55.

[0079] Step 2: Carton release and pre-alignment. The second cylinder 51 drives the moving plate 52 and the alignment plate 54 to move down as a whole. At the same time, the extrusion frame 53 fixed to the top of the pressing plate 65 moves down as well. It extrudes the second extrusion block 615 through the second extrusion groove on its inner side, causing the extrusion plate 614 to move horizontally. This forces the air in the second air groove into the first air groove of the pressing plate 65, driving the first piston 67 and the rack 68. The gear 69 drives the pressing plate 65 to rotate from horizontal to vertical to make room. At this time, the vertical pressing plate 65 limits the downward movement of the first extrusion rod 56, so that the support plate 55 can be contracted through the first extrusion block 57. The carton is released and falls at a fixed height. As it continues to move down, the inclined surface of the alignment plate 54 assists in guiding and aligning the carton stack.

[0080] Step 3: Stacking and Compacting and State Reset. After the cartons are stacked on the stack, the second cylinder 51 drives the moving plate 52 and the squeezing frame 53 to rise and reset. Under the action of the second compression spring 613, the squeezing plate 614 and the second piston 610 of the adjusting component are reset, the air pressure is drawn back, and the first piston 67 and the rack 68 are reset. Then, the pressing plate 65 is driven to flip back from the vertical state to the horizontal state. At the same time, the motor 619 of the pressing adjustment mechanism 6 is started, driving the screw 61 to rotate, so that the lifting plate 63 drives the fixed frame 64 and the pressing plate 65 that has been restored to the horizontal position to move up a distance equal to the thickness of a carton along the slide rod 62, so that the pressing plate 65 is pressed firmly on the top carton.

[0081] Step 4: Repeat steps 1 to 3 until the preset number of carton layers are stacked automatically to form a carton stack, which is ready for subsequent packaging or transportation.

10. A conveying method for a corrugated cardboard box stacking and conveying device according to any one of claims 1-9, characterized in that, The specific usage steps are as follows: Step 1: Carton grabbing and transfer. The controller (7) starts the conveyor (2) and intermittently transports a single corrugated carton to the designated position. The first cylinder (41) in the pushing mechanism (4) drives the pushing frame (42) to move above the carton. The air pump (44) works to make the suction cup (43) generate negative pressure and suck up the carton. Then the first cylinder (41) moves the carton horizontally into the stacking box (3) and places it on the support plate (55). Step 2: Carton release and pre-alignment. The second cylinder (51) drives the moving plate (52) and the alignment plate (54) to move down as a whole. At the same time, the extrusion frame (53) fixed to the top of the pressing plate (65) moves down and extrudes the second extrusion block (615) through the second extrusion groove on its inner side, causing the extrusion plate (614) to move horizontally. This forces the air in the second air groove into the first air groove of the pressing plate (65), driving the first piston (67) and the rack (68) to make the gear (69) drive the pressing plate (65) to flip from horizontal to vertical to make room. At this time, the vertical pressing plate (65) limits the downward movement of the first extrusion rod (56), so that the support plate (55) can be contracted through the first extrusion block (57). The carton is released and falls at a fixed height, and when it continues to move down, the inclined surface of the alignment plate (54) assists in guiding and aligning the carton stack. Step 3: Stacking and compaction and state reset. After the cartons are stacked on the stack, the second cylinder (51) drives the moving plate (52) and the squeezing frame (53) to rise and reset. Under the action of the second compression spring (613), the squeezing plate (614) and the second piston (610) of the adjusting component are reset, the air pressure is drawn back, and the first piston (67) and the rack (68) are reset, thereby driving the pressing plate (65) to flip back from the vertical state to the horizontal state. At the same time, the motor (619) of the pressing adjustment mechanism (6) is started, driving the screw (61) to rotate, so that the lifting plate (63) drives the fixed frame (64) and the pressing plate (65) that has been restored to the horizontal position to move up by a distance equal to the thickness of a carton, so that the pressing plate (65) is pressed firmly on the top carton. Step 4: Repeat steps 1 to 3 until the preset number of carton layers are stacked automatically to form a carton stack, which is ready for subsequent packaging or transportation.
