In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0032] like Figures 1-6 As shown, this utility model provides an automatic loading and unloading device for a slotting machine.

[0033] In an exemplary embodiment, the slotting machine automatic loading and unloading device includes a frame 1, which has three areas: a loading area 101, a transfer area 102, and a unloading area 103. The unloading area 103 is located above the loading area 101, and the transfer area 102 is located behind the loading area 101. The transfer area 102 has a transfer station 1021 and a working station 1022. The transfer station 1021 is located on one side of the loading area 101, and the working station 1022 is located on one side of the unloading area 103. A transfer mechanism is mounted on the frame 1 and includes a drive assembly and a transfer feeding belt 3. The drive assembly can drive the transfer feeding belt 3 to move vertically and switch between the loading area 101 and the unloading area 103. A pushing mechanism is mounted on the frame 1 and is used to sequentially push multiple material frames from the working station to the unloading area 103.

[0034] In this embodiment, a complete automated process for material boxes, from loading at a low level to unloading at a high level, is achieved through a reasonable spatial layout and the coordination of automated mechanisms. Specifically, the three-zone division of frame 1 optimizes the material box flow path, the vertical transport function of the transfer mechanism solves the problem of material box height conversion, and the pushing mechanism enables continuous conveying of material boxes at the working position. Specifically, when the transfer conveyor belt 3 receives a full material box from the loading area 101 at the transfer station 1021, it rises vertically to the working position through the action of the drive component. The slotting machine's robotic arm transfers the material pieces from the material box. After all the material pieces in a single material box have been transferred, the pushing mechanism pushes the empty material box to the unloading area 103. This invention significantly improves loading and unloading efficiency by replacing manual operation with mechanical automation, reduces manual intervention, and enables the slotting machine to achieve continuous and stable automated production.

[0035] For example, in this embodiment, the feeding area 101 is provided with a feeding conveyor belt 2 to receive external materials, wherein fully loaded material frames are stacked vertically and enter the feeding area 101.

[0036] It is worth noting that in this embodiment, when the transfer feeding belt 3 is at the transfer station 1021, it is flush with the loading conveyor belt, and when the transfer feeding belt 3 is at the working station 1022, it is flush with the unloading conveyor belt 24.

[0037] It should also be noted that the material frame in this embodiment is a frame structure, which is square in shape and can be conveyed on the conveyor belt. The material frame has multiple workstations for placing sheet materials. When the material frame is fixed to the workstation 1022, the robotic arm on the slotting machine will grab the sheet material in the material frame and slot it.

[0038] In one exemplary embodiment, the drive assembly includes a mounting plate 6 fixed on the frame 1 and vertically disposed on the bottom surface of the frame 1. A rack 7 is disposed on the mounting plate 6 along the height direction. A drive motor 4 is disposed on the transfer feed belt 3. A drive gear 5 is disposed at the output end of the drive motor 4. The drive gear 5 meshes with the rack 7. A slide rail 8 is disposed on the mounting plate 6. A slider 9 is disposed on the transfer feed belt 3 and slidably connected to the slide rail 8. The drive motor 4 drives the transfer feed belt 3 to move in the height direction through the drive gear 5 and switches between the loading area 101 and the unloading area 103.

[0039] In this embodiment, the precise and stable movement of the transfer feed belt 3 in the height direction is achieved through a dual constraint mechanism of gear-rack 7 meshing transmission and slide rail 8-slider 9 guidance. Specifically, the gear-rack 7 converts the motor's rotational motion into linear motion, providing the main driving force; the slide rail 8 and slider 9 restrict other degrees of freedom, eliminating lateral offset. The combined effect of these two mechanisms effectively suppresses the swaying and jamming phenomena common in traditional lifting mechanisms.

[0040] For example, the mounting plate 6 can be made of steel plate or aluminum alloy plate with a thickness of 10-20mm, and is fixed to the frame 1 by bolts. The rack 7 has a module of 2-4, and its length is determined according to the lifting stroke. It is made of alloy steel and has been quenched. The drive motor 4 is preferably a servo motor or a stepper motor to control the forward or reverse rotation of the drive gear 5 to realize the lifting or lowering of the transfer feed belt 3.

[0041] In an exemplary embodiment, the frame 1 is provided with a positioning mechanism for positioning material boxes. The positioning mechanism is located at the work station 1022 to position each material box, ensuring accurate positioning of the material box and enabling the robotic arm of the slotting machine to accurately position the sheet material for stable gripping. The positioning mechanism includes a first positioning component and a second positioning component. The first positioning component is set in the left-right direction of the transfer feeding belt 3 for positioning the material box in the left-right direction, and the second positioning component is set in the front-back direction of the transfer feeding belt 3 for positioning the material box in the front-back direction.

[0042] In this embodiment, the positioning accuracy problem of the material frame at the workstation 1022 is effectively solved by setting a bidirectional positioning mechanism. The positioning mechanism, located at workstation 1022, ensures accurate positioning of the material frame at the processing position. The first and second positioning components constrain the material frame from the left and right and front and back directions, respectively, forming a complete planar positioning system. The left-right positioning achieves centering of the material frame through symmetrically arranged positioning components, while the front-back positioning ensures accurate processing position through end-capsulation or bidirectional clamping. The coordinated work of the two positioning components ensures the material frame is completely fixed in the horizontal plane, preventing positional shifts during processing, thereby improving processing accuracy and efficiency. Compared with existing technologies, this solution replaces manual positioning with mechanical positioning, significantly improving positioning accuracy and operational efficiency.

[0043] For example, the first positioning component includes a first positioning cylinder 10 and a second positioning cylinder 13. The first positioning cylinder 10 and the second positioning cylinder 13 are respectively located on the left and right sides of the transfer feeding belt 3. The output end of the first positioning cylinder 10 is provided with a first positioning plate 11, and the bottom of the first positioning plate 11 is provided with a first fixing plate 12. The output end of the second positioning cylinder 13 is provided with a second positioning plate 14, and the bottom of the second positioning plate 14 is provided with a second fixing plate 15. The first positioning cylinder 10 and the second positioning cylinder 13 can be used to drive the first positioning plate 11 and the second positioning plate 14 to move closer to each other and clamp the material frame. In this embodiment, the first positioning cylinder 10 and the second positioning cylinder 13 are symmetrically arranged, and the precise centering and positioning of the material frame is achieved through the symmetrically arranged dual-cylinder drive mechanism. During operation, the two cylinders act synchronously, driving the positioning plates to clamp the material frame from both sides simultaneously to achieve fixation, preventing the material frame from moving when the slotting machine's robotic arm grabs the sheet material. The fixing plate provides a stable support foundation. Compared with existing single-sided positioning methods, this design eliminates positioning deviations caused by unilateral force application, and the positioning accuracy can be controlled within ±0.05mm. Due to the use of automated mechanical positioning, the positioning time is reduced from 5-8 seconds of manual operation to less than 1 second, and positioning errors caused by human factors are avoided. The cylinder-driven clamping mechanism features fast response and high repeatability. The rigid support of the fixed plate effectively suppresses vibration during clamping, thus ensuring the stability of the positioning process. In a specific embodiment, the first positioning cylinder 10 and the second positioning cylinder 13 can be double-acting cylinders, whose stroke is adjustable according to the material frame size. Polyurethane buffer pads can be added to the surfaces of the first positioning plate 11 and the second positioning plate 14 to prevent damage to the material frame. The first fixed plate 12 is integrally set with the first positioning plate 11, forming an L-shaped support surface. The second fixed plate 15 is set in the same way as the second positioning plate 14.

[0044] For example, in this embodiment, the first positioning component further includes a third positioning cylinder 16 and a positioning block 17. The third positioning cylinder 16 is disposed on the front and rear sides of the first positioning cylinder 10, and the positioning block 17 is disposed on the front and rear sides of the second positioning cylinder 13. The third positioning cylinder 16 can be used to push the material frame to abut against the positioning block 17. By adding a symmetrically arranged third positioning cylinder 16 and positioning block 17, after the material frame completes left and right positioning, the slotting operation is performed. After the slotting is completed, the material frame becomes empty. At this time, the third positioning cylinder 16 pushes the material frame and positioning block 17, and the second positioning cylinder 13 retracts a certain distance simultaneously. However, it is necessary to ensure that the first fixing plate 12 and the second fixing plate 15 are located below the material frame to form support. The material frame forms rigid contact between the third positioning cylinder 16 and positioning block 17. Since the first positioning cylinder 10 is not moving, the material frame moves as a whole towards the direction of the second positioning cylinder 13, thus detaching from the first positioning plate 11. After the third positioning cylinder 16 retracts, the material frame becomes free and is supported by the first fixing plate 12 and the second fixing plate 15 on both sides. At this time, the pushing mechanism can push the material frame towards the unloading area 103.

[0045] For example, in this embodiment, the output end of the third positioning cylinder 16 is provided with a rubber plate to avoid damaging the outer wall of the material frame.

[0046] In an exemplary embodiment, the second positioning component includes a fourth positioning cylinder 18 and a limiting block 20. The fourth positioning cylinder 18 is mounted on the frame 1 and is positioned between the working station 1022 and the unloading area 103. The output end of the fourth positioning cylinder 18 is provided with a fifth positioning cylinder 19, which can be used to push the material frame against the limiting block 20.

[0047] In this embodiment, the precise positioning of the material frame in the front-to-back direction is achieved through the coordinated action of two-stage cylinders. The fourth positioning cylinder 18 provides the initial driving force, the fifth positioning cylinder 19 completes the final fine-tuning push, and the limiting block 20 serves as a rigid reference to ensure positioning repeatability. Compared to manual positioning, this structure can shorten the positioning time to less than 0.5 seconds, and control the positioning accuracy within ±0.1mm. Flexible positioning of material frames of different weights can be achieved through cylinder pressure adjustment, avoiding damage to the material frame caused by rigid mechanical contact. During the positioning process, the fourth positioning cylinder 18 first pushes the fifth positioning cylinder 19 to the preparatory position, and then the fifth positioning cylinder 19 performs the precise pushing action. This staged control method effectively reduces positioning impact.

[0048] In this embodiment, the fourth positioning cylinder 18 can be a double-acting cylinder or a servo cylinder, and its installation position is fixed to the front plate of the working position by bolts. The cylinder stroke is set to 50-100mm according to the size of the material frame. The fifth positioning cylinder 19 is preferably a short-stroke thin cylinder, and its output end can be equipped with a polyurethane buffer pad to reduce impact. The limit block 20 is made of hardened steel and is fixed to the side of the frame 1 by an adjustable bracket. Its contact surface is provided with a wear-resistant coating. In a specific embodiment, the contact end between the fifth positioning cylinder 19 and the material frame can be replaced with a vacuum suction cup or an electromagnet to adapt to the positioning requirements of material frames of different materials.

[0049] In an exemplary embodiment, the pushing mechanism includes a pushing cylinder 22 disposed on the frame 1, and a pushing plate 23 is provided at the output end of the pushing cylinder 22. The pushing cylinder 22 can be used to drive the pushing plate 23 to move along the feeding direction of the transfer feeding belt 3.

[0050] In this embodiment, automated mechanical pushing replaces manual operation. The linear motion characteristics of the pushing cylinder 22 ensure precise and controllable pushing process, and the structural design of the pushing plate 23 achieves stable contact and pushing of the material frames. The pushing plate 23 can sequentially push multiple material frames placed on the transfer feeding belt 3, allowing the material frames to enter the unloading area 103 one after another, thus enabling the transfer of multiple material frames at once. Compared with the prior art, this solution solves the problems of low efficiency and poor positioning accuracy of manual pushing. The cylinder drive realizes automated control of the pushing process, and the pushing force is uniform and controllable, avoiding damage to the material frames caused by manual operation. The continuous pushing function of the pushing plate 23 significantly improves the material frame transfer efficiency. Multiple material frames can be transferred in a single pushing cycle, thereby improving the overall working efficiency of the slotting machine.

[0051] For example, the pusher cylinder 22 can be a double-acting cylinder or a single-acting cylinder. The cylinder stroke is adjusted according to the material frame size and pushing distance, and the specific stroke range can be set to 100-300mm. The pusher plate 23 can be made of metal sheet or engineering plastic, and its contact surface can be equipped with a rubber pad or silicone layer to increase the friction coefficient and prevent the material frame from sliding. The connection method between the pusher plate 23 and the cylinder output end includes threaded connection, snap-fit ​​connection or flange connection. The installation position of the pusher cylinder 22 can be set to the side or above the transfer feeding belt 3, and the specific position can be adjusted according to the structure of the frame 1. The control of the pusher cylinder 22 can be realized by using a solenoid valve in conjunction with a PLC. The pushing force is controlled by adjusting the air pressure, and the air pressure range is usually set to 0.4-0.6MPa. The movement trajectory of the pusher plate 23 can be guided by a linear guide rail or slide rail 8 to ensure the linear accuracy of the pushing process. The width of the pusher plate 23 can be designed to be slightly larger than the width of the material frame, specifically exceeding the width of the material frame by 10-20mm, to ensure pushing stability.

[0052] For example, multiple guide wheel groups 21 are provided between the working station 1022 and the unloading area 103, and the guide wheel groups 21 are mounted on the frame 1.

[0053] Because multiple material boxes are stacked, the transfer conveyor belt 3 cannot transfer the upper material boxes. Therefore, the pusher plate 23 can sequentially move the multiple stacked material boxes, while the guide wheel group 21 plays a transition role. Once the material box comes into contact with the unloading conveyor belt 24, it can be transported to the designated place for storage.

[0054] In an exemplary embodiment, the unloading area 103 includes an unloading conveyor belt 24 and a top-loading cylinder 25 disposed between the unloading conveyor belt 24. Both the unloading conveyor belt 24 and the top-loading cylinder 25 are disposed on the frame 1. The output end of the top-loading cylinder 25 is provided with a top-loading plate 26, which can be used to drive the material frame to move in the vertical direction.

[0055] In this embodiment, the material frames are horizontally transported via the unloading conveyor belt 24, while the top-loading cylinder 25 drives the top-loading plate 26 for intermittent vertical lifting. Specifically, when a material frame is transported to the unloading area 103 by the conveyor belt, the top-loading cylinder 25 is activated and lifts the material frame to a predetermined height. Subsequent material frames continue to be transported below the previously lifted material frame, thus achieving the stacking of material frames. This mechanical positioning method allows for the stacking of 5-10 material frames in a single unloading operation, improving efficiency by more than 300% compared to traditional manual single-piece handling. The coordinated action of the top-loading plate 26 and the conveyor belt controls the positioning accuracy within ±0.5mm, effectively solving the positioning deviation problem caused by manual operation. By automatically controlling the lifting sequence and the start and stop of the conveyor belt, continuous operation of material frame transfer and stacking is achieved.

[0056] For example, the top-loading cylinder 25 can be a single-acting or double-acting cylinder, and its stroke range can be set according to the required stacking height of the material frames, for example, 50-200mm. The top-loading plate 26 can be a rectangular metal plate, and a rubber anti-slip layer or rubber layer can be added to the surface to prevent the material frames from sliding. The unloading conveyor belt 24 can be a synchronous belt or a roller structure, and the belt speed can be adjusted from 0.1-1m / s to adapt to different production cycles. As a preferred embodiment, the distance between the top-loading cylinder 25 and the unloading conveyor belt 24 is set to 1.2-1.5 times the length of the material frame to ensure the stability of the material frame during the lifting process. Furthermore, the edge of the top-loading plate 26 can be provided with a guide slope to facilitate the material frame sliding into the predetermined position.

[0057] For example, support cylinders 27 are provided on both sides of the unloading conveyor belt 24, and support plates 28 are provided at the output ends of the support cylinders 27. The support cylinders 27 on both sides can be used to drive the support plates 28 to move closer or further apart. By providing movable support plates 28 on both sides of the unloading conveyor belt 24, lateral clamping is formed during the material frame transfer process, effectively preventing the material frame from shifting or falling. Specifically, when the material frame is lifted off the conveyor belt by the top-loading cylinder 25, the support plates 28 on both sides move closer simultaneously to form a clamping space, accurately positioning and fixing the material frame, and the top-loading cylinder 25 resets simultaneously. After clamping, the support plate 28 remains stationary, ensuring the material frame stays stably in the predetermined position. When the next material frame needs to be fixed, the material frame enters the unloading area 103, positioned below other material frames and above the top plate 26. The top cylinder 25 pushes the top plate 26 to contact the bottommost material frame, and the support plate 28 moves outward to release the clamping. The top cylinder 25 then moves the empty material frame upward, with the bottommost material frame supporting the upper material frames until the lower material frames rise to a certain height and align with the support plate 28. At this point, the support plates 28 move closer together to clamp the bottommost material frame, thus supporting all empty material frames. The top cylinder 25 then resets, clearing space for the material frames to enter. This design solves the problem of the traditional unloading conveyor belt 24 lacking lateral support. By replacing manual intervention with mechanical clamping, it improves the stability and automation of unloading. Compared with existing technologies, this solution has a simple and reliable structure, fast response, and can adapt to the clamping requirements of material frames of different sizes, significantly improving unloading efficiency and accuracy.

[0058] For example, in this embodiment, the support plate 28 is an L-shaped fixing plate, and the horizontal part of the support plate 28 provides the main support for the material frame.

[0059] For example, in this embodiment, the unloading area 103 is provided with symmetrically placed guide plates 29 to guide the material frame and ensure the stability of the material frame entering the unloading area 103.

[0060] In summary, this invention can improve the automation performance of the slotting machine's material frame during loading and unloading, reduce manual labor load, and effectively improve the slotting efficiency of the slotting machine, thereby increasing the production line's capacity.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
