Description

Technical Field

[0001] This invention belongs to the field of packaging equipment technology, specifically an automatic handling device and method. Background Technology

[0002] With the booming express delivery industry, cardboard boxes are becoming increasingly popular as a common packaging material. The production of cardboard boxes involves processes such as material selection, cutting of cardboard, embossing, folding and gluing, flattening and finishing. When the material selection is completed, the selected cardboard needs to be moved, which is usually done by a transport vehicle in the workshop.

[0003] A Chinese patent with publication number CN105059852B describes a cardboard box transporter, including a base plate with multiple wheels on its bottom surface. A handle is fixed to the outer wall of a baffle at the rear of the base plate. The base plate has a groove in its center, and its front sidewall is an arc-shaped sidewall with a central arc-shaped sidewall that communicates with the front of the groove. A limiting protrusion is located in the center of the groove, forming two sliding grooves with the left and right sidewalls of the groove. Two sliding strips are inserted into the sliding grooves on the bottom surface of the transport box, which rests against the base plate. Fixed plates are located on the upper part of the inner sidewalls of the left and right sidewalls of the transport box. A drive motor is fixed to the fixed plates, and an adjusting screw is screwed to the output shaft of the drive motor. The lower end of the adjusting screw is hinged to a pressure plate. This vehicle can transport folded cardboard boxes, and the pressure plate ensures the cardboard is kept compressed, preventing damage.

[0004] The aforementioned patent uses a pressure plate to ensure the cardboard is kept compressed and less prone to damage. However, in actual handling, cardboard is usually not bundled when transported by a trolley for ease of loading and unloading. The pressure plate can press the stacked cardboard together, and when the trolley brakes at the designated position, the pressure plate presses the cardboard to counteract the inertial force acting on it, preventing the cardboard from moving out of the trolley due to inertia and ensuring the stability of the cardboard during transport. However, when the pressure plate squeezes the cardboard, it can easily leave indentations on the surface, leading to a decrease in the quality of the cardboard and consequently affecting the quality of the finished carton.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1 to 3As shown, an automatic handling device according to an embodiment of the present invention includes a handling platform 1, a partition 11 at one end of the handling platform 1, and a plurality of driving components 13 at the bottom of the handling platform 1 for moving the handling platform 1; a receiving plate 12 is provided above the handling platform 1, and a pair of receiving strips 121 are provided symmetrically at the bottom of the receiving plate 12 based on the center, and an arc-shaped groove is formed at the bottom of the receiving strip 121, and a top block 21 is provided in the arc-shaped groove; a pair of first hydraulic cylinders 2 are provided at the bottom of the handling platform 1 and directly below the top block 21; the output end of the first hydraulic cylinder 2 extends through to the top of the handling platform 1 and is connected to the bottom of the top block 21; a pair of baffles 14 are symmetrically arranged on the top surface of the receiving plate 12 based on the center line;

[0039] In actual handling, cardboard is usually not bundled when transported by a transport vehicle for easy loading and unloading. A pressure plate can press the stacked cardboard together. When the transport vehicle moves to the designated position and brakes, the pressure plate presses the cardboard to counteract the inertial force on the cardboard, preventing the cardboard from moving out of the transport vehicle due to inertia and ensuring the stability of the cardboard handling. However, when the pressure plate squeezes the cardboard, it can easily squeeze indentations on the surface of the cardboard, resulting in a decrease in the quality of the cardboard, which in turn affects the quality of the prepared carton.

[0040] To address the aforementioned problems, this embodiment of the invention includes a receiving plate 12. In use, cardboard is stacked onto the top surface of the receiving plate 12 using cardboard production equipment. Specifically, during cardboard production, the equipment includes a cutting device and a transfer device. After cutting, the cardboard is transferred using the transfer device, which can be a suction cup or a hoisting mechanism. The cardboard is attracted by the suction cup and then hoisted for transfer. The stacking of the cardboard on the receiving plate 12 is achieved through the cooperation of the suction cup and the hoisting mechanism. Alternatively, the transfer device can also be a conveyor belt or an automatic stacking machine.

[0041] During transport, the first hydraulic cylinder 2, away from the baffle 14, is activated. Through the top block 21 and the receiving strip 121, one bottom end of the receiving plate 12 is lifted, causing the receiving plate 12 to tilt. The cardboard on the top surface of the receiving plate 12 tilts synchronously, and the end of the cardboard is received by the baffle 14. Then, the driving component 13 drives the transport vehicle 1 to move. During the movement, the speed needs to be reduced when turning to avoid tipping over. Therefore, the cardboard is subjected to low inertia when turning, making it difficult for it to move out of the receiving plate 12. When moving in a straight line, in order to improve transport efficiency, the transport vehicle 1 is driven to move quickly. When it reaches the designated position, the driving component 13 brakes. At this time, the cardboard on the receiving plate 12 is subjected to greater inertia. Since the receiving plate 12 is tilted at this time, the stacked cardboard tilts synchronously, which cancels out the inertial drive of the cardboard, thereby preventing the cardboard from falling off the receiving plate 12. There is no need to squeeze the cardboard with a pressure plate to avoid the cardboard being pressed with indentations, thus preventing the quality of the carton from being affected.

[0042] like Figures 4 to 6 As shown, a connector 15 is provided on the side of the baffle 14 facing the center of the receiving plate 12. A rectangular airbag 16 is provided on the side of the connector 15, and a hose 17 is connected to the top of the rectangular airbag 16. An air pump is connected to the end of the hose 17 away from the rectangular airbag 16. When the receiving plate 12 is tilted, the end of the cardboard moves toward the side of the baffle 14. The baffle 14 supports the end of the cardboard through the rectangular airbag 16 on the side of the connector 15. The rectangular airbag 16 is inflated by the air pump connected to the hose 17. The rectangular airbag 16 expands, so the end of the cardboard is cushioned when it presses against the rectangular airbag 16, preventing the end of the cardboard from being deformed and damaged due to excessive pressure.

[0043] A slot 3 is provided on the top surface of the receiving plate 12 and directly below the connector 15. The bottom end of the connector 15 is inserted into the slot 3. A support spring 31 is provided between the bottom end of the connector 15 and the inner wall of the slot 3. During the movement of the transport vehicle plate 1, when it encounters uneven ground, it will vibrate up and down, which will then drive the cardboard on the receiving plate 12 to vibrate up and down synchronously. When the cardboard vibrates up and down, the connector 15 vibrates up and down synchronously in the slot 3, which drives the rectangular airbag 16 to vibrate up and down synchronously. The connector 15 is slidably connected to the baffle 14. Therefore, the end of the cardboard vibrates up and down synchronously with the rectangular airbag 16, avoiding friction caused by the movement of the end of the cardboard relative to the rectangular airbag 16, which could lead to damage.

[0044] like Figures 7 to 9 As shown, a receiving component is provided on the side of the partition 11 facing away from the center of the transport vehicle plate 1; a bracket 52 is provided at the top of the receiving component, and a fixing frame 53 is provided at the end of the bracket 52 away from the connecting component. A first motor 54 is installed on the side of the fixing frame 53, and a rotating roller 55 is provided at the output end of the first motor 54; when the cardboard is stacked on the top surface of the receiving plate 12, the rotating roller 55 of the fixing frame 53 is driven to move downward through the cooperation of the receiving component and the bracket 52. The rotating roller 55 stops when it presses against the topmost cardboard of the stack, and the pressure of the rotating roller 55 on the cardboard is controlled to avoid the cardboard being squeezed and indented. At the same time, the first motor 54 is started, and the first motor 54 drives the rotating roller 55 to rotate. Relative to the sliding of the cardboard surface, the frictional force continuously drives the top cardboard of the stack to move towards the baffle 14. When the transport vehicle 1 brakes, the top cardboard of the stack is most likely to move relative to the receiving plate 12 due to inertia. When the top cardboard of the stack moves relative to the receiving plate 12 during braking, the rotating roller 55 drives the top cardboard of the stack to return to its original position through frictional force, thereby ensuring the stability of the cardboard transport. Moreover, the rotating roller 55 does not need to excessively squeeze the cardboard, resulting in indentations on the cardboard. It should be noted that the top cardboard of the stack is in an inclined state. In actual transport, by controlling the moving speed of the transport vehicle 1, the situation where the top cardboard of the stack completely falls off the receiving plate 12 will not exist.

[0045] Multiple annular airbags 56 are fitted onto the surface of the rotating roller 55. When the rotating roller 55 presses against the surface of the topmost stacked cardboard, the annular airbags 56 are activated to press against the cardboard surface simultaneously. The annular airbags 56 deform when in contact with the cardboard, thereby increasing the pressure area of ​​the cardboard and further preventing the cardboard from being squeezed and developing indentations.

[0046] The receiving assembly includes a receiving cylinder 5, with a friction plate 51 inserted through the inside of the receiving cylinder 5. The top of the friction plate 51 is connected to the end of the bracket 52 away from the fixed frame 53. A through hole 111 is provided on the side of the partition plate 1 facing the center of the transport vehicle plate 1. A second motor 4 is provided at the opening of the through hole 111, with the output end of the second motor 4 passing through the through hole 111. A friction wheel 40 is provided at the end of the output end of the second motor 4, and the friction wheel 40 abuts against the side of the friction plate 51. When using the rotating roller 55, it is necessary to control... The pressure between the rotating roller 55 and the cardboard is controlled by a second motor 4, which drives the friction wheel 40 to rotate. The friction wheel 40 and the friction plate 51 generate sliding friction, and the magnitude of the sliding friction is fixed. The friction plate 51 passes through the receiving cylinder 5 and remains stable. Therefore, the downward friction force on the friction plate 51 is constant. Thus, the friction plate 51 drives the bracket 52 and the fixed frame 53 to effectively control the pressure of the rotating roller 55 on the surface of the cardboard, and remains stable when the cardboard fluctuates up and down during the handling process.

[0047] The surface of the second motor 4 is provided with a fixing member 41; a second hydraulic cylinder 42 is provided on one side of the fixing member 41, the housing part of the second hydraulic cylinder 42 is installed on the side of the partition 11, and the output end of the second hydraulic cylinder 42 is connected to the fixing member 41; in use, for different materials of cardboard, the force of the rotating roller 55 to squeeze the cardboard is different, so the second hydraulic cylinder 42 is provided. The second hydraulic cylinder 42 drives the friction wheel 40 to move laterally through the fixing member 41, so that the squeezing of the friction wheel 40 on the friction plate 51 is changed, thereby adjusting the friction between the friction wheel 40 and the friction plate 51. Correspondingly, the squeezing force of the rotating roller 55 on the cardboard is adjusted; it should be noted that when the position of the second motor 4 is adjusted, the output end of the second motor 4 moves within the through hole 111 and will not be blocked by jamming.

[0048] like Figures 1 to 10As shown, when unloading the transported cardboard, the rotating roller 55 is controlled to rotate, driving the topmost cardboard to move away from the transport vehicle plate 1; a positioning plate 6 is installed on the side of the transport vehicle plate 1, and a sliding notch 61 is opened on the side of the positioning plate 6. An intercepting rod 62 is inserted into the sliding notch 61, and a blocking plate 66 is set on the side of the intercepting rod 62; a rectangular nut 63 is set on the side of the positioning plate 6; a lead screw 65 is engaged and inserted into the rectangular nut 63; a third motor 64 is set at the top of the positioning plate 6, and the bottom end of the output end of the third motor 64 is connected to the top end of the lead screw 65; when unloading, the rotating roller 55 is controlled to rotate in the opposite direction, and at the same time the receiving plate 12 is restored to horizontal. The rotating roller 55 moves the cardboard drive box away from the receiving plate 12 through friction, which facilitates the unloading of the cardboard;

[0049] In addition, during the unloading of cardboard, the topmost cardboard is gradually unloaded. By setting up a baffle plate 66, the lower part of the topmost cardboard can be blocked, preventing the cardboard below from being moved simultaneously when the topmost cardboard is unloaded, thus affecting the unloading process. Furthermore, by starting the third motor 64, the third motor 64 drives the lead screw 65 to rotate, which meshes with the rectangular nut 63. The rectangular nut 63 drives the intercepting rod 62 to move downward synchronously, and the intercepting rod 62 drives the baffle plate 66 to move downward synchronously, coordinating with the unloading of the cardboard.

[0050] like Figure 11 As shown, an automated handling method includes the following steps:

[0051] S1. Feeding: When in use, the cardboard is stacked on the top surface of the receiving plate 12 using cardboard production equipment;

[0052] S2, Control: During handling, the first hydraulic cylinder 2 away from the baffle 14 is activated, the receiving plate 12 tilts, and the cardboard on the top surface of the receiving plate 12 tilts synchronously.

[0053] S3, Movement: The transport vehicle plate 1 is then moved by the drive assembly 13; when it reaches the designated position, the drive assembly 13 brakes.

[0054] S4. Unloading: After the transport vehicle 1 stops, unload the cardboard from the receiving plate 12.

[0055] During operation, cardboard is stacked onto the top surface of the receiving plate 12 using cardboard production equipment. Specifically, the cardboard production equipment includes a cutting structure and a transfer structure. After cutting, the cardboard is transferred using the transfer structure, which includes suction cups and hoisting machinery. The cardboard is then picked up by the suction cups and hoisted for transfer. The stacking of the cardboard on the receiving plate 12 is accomplished by the cooperation of the suction cups and the hoisting machinery. During handling, the first hydraulic cylinder 2, away from the baffle 14, is activated. The top block 21, in conjunction with the receiving strip 121, lifts one bottom edge of the receiving plate 12, causing the receiving plate 12 to... When tilting occurs, the cardboard on the top surface of the receiving plate 12 tilts synchronously. The end of the cardboard is received by the baffle 14, and then the driving assembly 13 drives the transport vehicle plate 1 to move. During the movement, the speed needs to be reduced when turning to avoid tipping over. Therefore, the cardboard experiences low inertia when turning, making it difficult for it to move out of the receiving plate 12. However, during straight-line movement, to improve handling efficiency, the transport vehicle plate 1 is driven to move quickly. When it reaches the designated position, the driving assembly 13 brakes. At this time, the cardboard on the receiving plate 12 experiences greater inertia. 12 is tilted, so the stacked cardboard tilts synchronously, counteracting the inertial force on the cardboard and preventing it from falling off the receiving plate 12. There is no need to squeeze the cardboard with a pressure plate, avoiding indentations and ensuring the quality of the carton production. When the receiving plate 12 is tilted, the cardboard end moves towards the side of the baffle 14. The baffle 14 supports the cardboard end through a rectangular airbag 16 on the side of the connector 15. The rectangular airbag 16 is inflated by an air pump connected to a hose 17, causing the cardboard end to press against the rectangular airbag 16. The cardboard end is cushioned to prevent excessive pressure on the cardboard end, which could cause deformation and damage. During the movement of the transport vehicle plate 1, when it encounters uneven ground, it will vibrate up and down, which will then cause the cardboard on the receiving plate 12 to vibrate up and down synchronously. When the cardboard vibrates up and down, the connector 15 vibrates up and down synchronously in the insertion slot 3, which in turn causes the rectangular airbag 16 to vibrate up and down synchronously. The connector 15 is slidably connected to the baffle 14. Therefore, the end of the cardboard and the rectangular airbag 16 vibrate up and down synchronously, avoiding friction caused by the movement of the end of the cardboard relative to the rectangular airbag 16, which could lead to damage.

[0056] When the cardboard is stacked on the top surface of the receiving plate 12, the rotating roller 55 of the fixed frame 53 moves downward through the cooperation of the receiving component and the bracket 52. The rotating roller 55 stops when it presses against the topmost cardboard, and the pressure of the rotating roller 55 on the cardboard is controlled to prevent the cardboard from being squeezed and indented. At the same time, the first motor 54 is started, which drives the rotating roller 55 to rotate. The rotating roller 55 slides relative to the surface of the cardboard, and the friction force continuously drives the topmost cardboard to move towards the baffle 14. When the transport vehicle plate 1 brakes, the topmost cardboard is most likely to move relative to the receiving plate 12 due to inertia. When the brake is applied, the rotating roller 55 drives the cardboard to move relative to the receiving plate 12 through friction. The top cardboard is reset to its original position, ensuring stability during cardboard handling; and eliminating the need for excessive pressure from the rotating roller 55, which could cause indentations. It should be noted that the top cardboard is tilted during stacking; however, by controlling the movement speed of the transport vehicle 1, the top cardboard will not completely detach from the receiving plate 12. When the rotating roller 55 presses against the surface of the top cardboard, the annular airbag 56 is activated to simultaneously press against the cardboard surface. The annular airbag 56 deforms upon contact with the cardboard, increasing the pressure area and further preventing indentations. When using the rotating roller 55, the pressure between the roller 55 and the cardboard needs to be controlled. A second motor 4 is installed, which drives the friction wheel 40 to rotate. Sliding friction occurs between the friction wheel 40 and the friction plate 51, and the magnitude of this sliding friction is constant. Since the friction plate 51 remains stable through the receiving cylinder 5, the downward friction force on the friction plate 51 is constant. Therefore, the friction plate 51, along with the bracket 52 and the fixed frame 53, can effectively control the squeezing force of the rotating roller 55 on the cardboard surface, and maintain stability even when the cardboard fluctuates during transport. In use, different squeezing forces from the rotating roller 55 are required for different cardboard materials; therefore, a second hydraulic cylinder 42 is installed. The second hydraulic cylinder 42 drives the friction wheel 40 to move laterally through the fixed component 41, thereby changing the squeezing force of the friction wheel 40 on the friction plate 51. This adjusts the friction between the friction wheel 40 and the friction plate 51, and correspondingly, the squeezing force of the rotating roller 55 on the cardboard is adjusted. It should be noted that when the position of the second motor 4 is adjusted, the output end of the second motor 4 moves within the through hole 111 without being blocked. During unloading, the rotating roller 55 is controlled to rotate in the opposite direction, while the receiving plate 12 is restored to a horizontal position. The rotating roller 55 moves the cardboard drive box away from the receiving plate 12 through friction, facilitating the unloading of the cardboard. During cardboard unloading, the topmost cardboard is gradually unloaded. By setting the barrier plate 66, the lower part of the topmost cardboard can be blocked, preventing the lower cardboard from being moved simultaneously when the topmost cardboard is unloaded, thus affecting the unloading process.Furthermore, by activating the third motor 64, the lead screw 65 rotates, engaging with the rectangular nut 63 for transmission. The rectangular nut 63 then drives the intercepting rod 62 to move downwards synchronously, which in turn drives the blocking plate 66 to move downwards synchronously, coordinating with the unloading of the cardboard.
