Description

Technical Field

[0001] The present invention relates to the technical field of furniture manufacturing, and in particular to an automated sheet cutting device for furniture manufacturing. Background Art

[0002] Furniture is an essential item in people's lives, mostly assembled from wood, metal, and stone sheets. Furniture generally refers to large items such as wardrobes, tables, beds, and sofas. Sheets are the main materials in the processing of these furniture items. During the sheet processing, processing factories select sheets for processing and prefabrication according to customer customization requirements to facilitate the construction and assembly of finished products by workers. The most common step in processing is to cut the sheets. Different lengths and widths of sheets are used according to the manufacture of different furniture, so a cutting device is required.

[0003] In the prior art, there is a furniture sheet cutting and loading mechanism with the publication number of CN116572327A. By setting a pull rod, a clamping rod, and a clamping groove, after the stacking placement of the placement frame is completed, the pull rod is moved in a sliding manner, so that the clamping rod moves under the action of the pull rod, penetrates the frame, and extends into the clamping groove. At this time, the placement frame will be supported and limited under the action of the pull rod and the clamping rod, avoiding the situation that when the conveyor belt rotates, it is not easy to drive the placement frame located on the top of the conveyor belt to move. At the same time, by setting a telescopic rod, when the pull rod is slid and the clamping rod is separated from the clamping groove and the frame respectively, the setting of the telescopic rod can ensure the stability of the pull rod and avoid the situation of the pull rod falling off.

[0004] Although the above device can automatically load furniture sheets, there are still some defects in the actual processing process. Since the cutting device lacks an automatic unloading and sorting function, when cutting furniture cabinet doors, a sheet will be divided into six pieces. After cutting, the six cut sheets still need to be stacked one by one by workers and then moved to a tray for sorting, which is not only time-consuming and laborious, but also greatly reduces the production efficiency of the device.

[0005] Therefore, an automated sheet cutting device for furniture manufacturing is proposed to solve the above problems. Summary of the Invention

Detailed implementation manner

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0031] As Figure 1-10 shown, an automatic sheet cutting device for furniture manufacturing includes a cutting platform 1. A cutting mechanism 2 for automatically cutting sheets is provided on the cutting platform 1. The cutting mechanism 2 is mainly composed of a transverse movement mechanism, a cutting machine and a dust suction mechanism, which are mature technologies in the prior art and will not be described in detail here. A pushing mechanism 3 for automatically pushing the sheets for feeding is provided on the cutting platform 1. The pushing mechanism 3 is mainly composed of a longitudinal movement mechanism and a pushing plate and other structures, and can automatically push the sheets through the cutting mechanism 2 and move them onto the fixed frame 4, which are mature technologies in the prior art and will not be described in detail here. An outlet is provided on the rear side of the cutting platform 1 and away from one side of the pushing mechanism 3. Through the setting of the outlet, it is convenient for the blanking mechanism to push out the sheets. A blanking mechanism for pushing out the sheets is provided on the front side of the cutting platform 1 relative to the front side of the outlet. A cavity is opened at the top of the cutting platform 1, and a fixed frame 4 is fixedly connected inside the cavity. A top groove 5 is opened at the top of the fixed frame 4 beside the outlet. A plurality of top blocks 6 are slidably connected inside the top groove 5. A lower plate 7 is fixedly connected between the side walls of the plurality of top blocks 6. Sliding frames 8 are slidably connected to both the front and rear sides inside the fixed frame 4. Upper grooves 9 are opened at the top of the fixed frame 4 between the top blocks 6. A sliding plate 10 is slidably connected between the sliding frames 8 below the top blocks 6. Pushing blocks 11 are fixedly connected to the top of the sliding plate 10 at the positions inside the upper grooves 9. A stacking plate mechanism for jacking up the sliding plate 10 and then pushing the sliding frame 8 to move is provided inside the fixed frame 4;

[0032] Moreover, the pushing block 11 is arranged on the side away from the top block 6. The top end of the fixed frame 4 is flush with the feeding position of the cutting platform 1. A plurality of upper springs 12 are fixedly connected between the top of the lower plate 7 and the inner top end of the fixed frame 4. Through the arrangement of the upper springs 12, it is convenient to push the lower plate 7 and the top block 6 to move downward quickly for resetting during reset. A plurality of lower springs 13 are fixedly connected between the inner top end of the sliding frame 8 and the top of the sliding plate 10. Through the arrangement of the lower springs 13, it is convenient to push the sliding plate 10 to move downward for resetting during reset. The height of the top block 6 is half of the height of the pushing block 11, so that when the pushing block 11 pushes the plate to the side of the top block 6, it can still contact the plate, ensuring that the plate is completely stacked on the other three plates;

[0033] The stacking mechanism includes a pair of upper electric telescopic cylinders 14. The upper electric telescopic cylinders 14 are both fixedly connected to the side wall of the fixed frame 4. The bottom of the sliding plate 10 is fixedly connected with an extrusion plate 15. A right-angle block 16 with an inclined surface is slidably connected to the position below the extrusion plate 15 at the inner bottom end of the fixed frame 4. The output ends of the upper electric telescopic cylinders 14 both pass through the inner side of the fixed frame 4 and are fixedly connected to the side wall of the right-angle block 16. A pair of L-shaped rods 17 are fixedly connected to the side wall of the right-angle block 16. A through groove 18 is opened at the bottom end of the side wall of the sliding frame 8. A limiting block 19 is fixedly connected to the side wall of the L-shaped rod 17 at a position beside the through groove 18. A limiting mechanism for restricting its sliding position is arranged on the side wall of the sliding frame 8;

[0034] The blanking mechanism includes a pair of air cylinders 26. A pair of support frames 27 are arranged at the front side of the cutting platform 1 relative to the front inner side of the discharge port. The air cylinders 26 are both fixedly connected to the top ends of the support frames 27. A receiving groove is opened at the inner side of the cutting platform 1 relative to the front side of the discharge port. The receiving groove can be used to receive the blanking plate 28 to avoid hindering the normal pushing of the plates on the cutting platform 1. The blanking plate 28 is arranged inside the receiving groove. The output ends of the air cylinders 26 pass through the cutting platform 1 and are fixedly connected to the side wall of the blanking plate 28. Side plates 29 for restricting the position of the plates are arranged on the cutting platform 1. A sorting frame 30 is arranged at the rear side of the cutting platform 1 relative to the rear side of the discharge port;

[0035] During the cutting process of the sheet material, first place the sheet material on the cutting platform 1. Subsequently, the pusher mechanism 3 is used to push the sheet material through the cutting mechanism 2. Through the program setting of the cutting mechanism 2, the sheet material is cut into six pieces. Then, the cut sheet materials are pushed onto the fixed frame 4 by the pusher mechanism 3. Among them, three sheet materials are restricted by the side plate 29 and are neatly arranged beside the side plate 29 (under the restriction of the side plate 29 and the push of the pusher mechanism 3, the cut sheet materials can be neatly squeezed beside the side plate 29 to avoid tilting, which may affect the normal feeding of the subsequent device). And the three sheet materials close to the side plate 29 are pushed to a position beyond the top groove 5. Subsequently, the upper electric telescopic cylinder 14 can be controlled to start, driving the right-angle block 16 and the L-shaped rod 17 to move. Then, the inclined surface of the right-angle block 16 gradually pushes the extrusion plate 15 and the sliding plate 10 to slide upward (at this time, the sliding frame 8 is restricted by the limiting mechanism and cannot slide left and right), and gradually compresses the lower spring 13. At the same time, it drives the pushing block 11 to extend out of the upper groove 9. Meanwhile, the upward movement of the sliding plate 10 will push the lower plate 7 and the top block 6 to slide upward, causing the top block 6 to extend out of the top groove 5 and compressing the upper spring 12. At this time, due to the ejection of the top block 6, one end of the three sheet materials on the side away from the side plate 29 will be lifted up;

[0036] Then, through the continuous movement of the right-angle block 16, the extrusion plate 15 slides to the top of the right-angle block 16. At the same time, the limiting block 19 is driven by the L-shaped rod 17 to move inside the through groove 18, and the limiting mechanism's limitation on the sliding frame 8 is released. Then, under the action of the limiting block 19 pushing the inside of the through groove 18, the sliding frame 8 will be driven to slide inside the fixed frame 4, gradually compressing the return spring 20. At the same time, it will drive the sliding plate 10 between the sliding frames 8 to move, and drive the pushing block 11 to slide toward the side plate 29. Subsequently, the pushing block 11 moves beside the sheet material, and then the extended part of the pushing block 11 is used to push the sheet material to move along the direction in which the top block 6 is lifted. During this process, since the top block 6 is restricted by the top groove 5 and cannot slide left and right but can only slide up and down, the top block 6 will not slide together with the sliding plate 10, but the sliding plate 10 will maintain the extrusion on the top block 6. Then, the pushing block 11 passes between the upper groove 9 and the top block 6, and pushes the sheet material onto the other three sheet materials (when the pushing block 11 moves inside the top groove 5, the sheet material can be pushed onto the other three sheet materials);

[0037] Finally, the upper electric telescopic cylinder 14 can be controlled to retract, and the above operations are repeated in reverse for resetting. At the same time, the air cylinder 26 can be controlled to start, driving the blanking plate 28 to slide, and then gradually pushing the stacked sheet materials onto the sorting plate 31 to achieve the automatic blanking of the device.

[0038] To ensure that the sliding frame 8 can be quickly reset, a pair of reset springs 20 are fixedly connected between the inner side of the fixed frame 4 and the side wall of the sliding frame 8. Through the setting of the reset springs 20, when the upper electric telescopic cylinder 14 drives the limiting block 19 to reset and releases the extrusion at the through groove 18, the elastic force of the reset springs 20 can push the sliding frame 8 to quickly reset. The bottom end of the extrusion plate 15 is set as a smooth arc surface, which is convenient for the inclined surface of the right-angle block 16 to push the extrusion plate 15 to slide upward more smoothly, improving the smoothness during the operation of the device.

[0039] To ensure the normal operation of the device, the limiting mechanism includes limiting rods 21. A limiting plate 22 is fixedly connected to the side wall of the sliding frame 8. There are a pair of limiting rods 21, and the limiting rods 21 are all inserted through and slidably connected to the top end of the limiting plate 22. A limiting spring 23 is fixedly connected between the outer wall of the limiting rod 21 and the bottom end of the limiting plate 22. A limiting hole 24 is opened at the upper position of the inner top of the fixed frame 4 relative to the limiting rod 21. The bottom end of the limiting rod 21 abuts against the top end of the limiting block 19. The side of the limiting block 19 away from the right-angle block 16 is inclined. The bottom end of the limiting rod 21 is set as a smooth arc surface. A positioning plate 25 is fixedly connected to the inner side of the fixed frame 4 beside the limiting plate 22. The positioning plate 25 plays a role in limiting the sliding position of the limiting plate 22 and the sliding frame 8.

[0040] Through the setting of the limiting mechanism, when the upper electric telescopic cylinder 14 operates to drive the right-angle block 16, the L-shaped rod 17 and the limiting block 19 to move, and the extrusion slide plate 10 slides upward, the top end of the limiting rod 21 is inserted into the limiting hole 24 by the extrusion of the top end of the limiting block 19 on the limiting rod 21, which plays a role in limiting the sliding position of the sliding frame 8, avoiding the sliding frame 8 being pushed to move during the upward sliding of the extrusion slide plate 10, and ensuring the stability during the operation of the device. Subsequently, after the extrusion slide plate 10 moves upward to the designated position, the inclined surface on the side of the limiting block 19 will move below the limiting rod 21, and then gradually release the extrusion on the limiting rod 21. Then, under the elastic force of the limiting spring 23, the limiting rod 21 is gradually pushed to slide downward and slide out of the limiting hole 24. At the same time, the side end of the limiting block 19 moves to the inside of the through groove 18, and then drives the sliding frame 8 to move under the push of the limiting block 19, thereby driving the pushing block 11 to move and pushing the sheet material onto the other three sheet materials. Finally, during the reset, under the elastic force of the reset spring 20, the sliding frame 8 is pushed to gradually reset, so that the limiting plate 22 moves beside the positioning plate 25. The limited limiting plate 22 cannot continue to move. Then, under the extrusion of the inclined surface of the limiting block 19, the limiting rod 21 is gradually pushed to slide upward, so that the top end of the limiting rod 21 is inserted into the limiting hole 24 and compresses the limiting spring 23, thus completing the reset.

[0041] In order to automatically stack the cut plates, a sorting plate 31 is slidably connected inside the sorting frame 30. Both sides of the outer wall of the sorting frame 30 are fixedly connected with lower electric telescopic cylinders 32. Both sides of the sorting frame 30 are provided with sliding grooves. Both sides of the sorting plate 31 penetrate through the sliding grooves. The output end of the lower electric telescopic cylinder 32 is fixedly connected to the top end of the sorting plate 31. Inside the frame of the cutting platform 1, three travel switches 33 are fixedly connected at equal intervals above the side plate 29. And the travel switches 33 are arranged on the side plate 29, so the normal sliding adjustment of the side plate 29 will not be hindered. The top end of the blanking plate 28 is fixedly connected with a touch plate 34 for touching the travel switch 33. All three travel switches 33 are electrically connected to the lower electric telescopic cylinder 32 through a controller;

[0042] After six plates are stacked, the air cylinder 26 can be controlled to start and drive the blanking plate 28 to move, so that the plates are pushed out from the discharge port through the blanking plate 28 and pushed onto the sorting plate 31. During this process, when two of the rear plates fall onto the sorting plate 31, the touch plate 34 at this time will touch the travel switch 33. Then the travel switch 33 transmits a signal to the controller. The controller controls the air cylinder 26 to stop running and controls the lower electric telescopic cylinder 32 to move downward at a fixed distance, thereby driving the sorting plate 31 to move downward at a fixed distance to ensure the normal pushing of the subsequent plates. After that, after the operation is completed, the controller controls the air cylinder 26 to continue to move. Repeating like this, three double-layer plates can be sorted on the sorting plate 31 in turn without manual operation, greatly improving the convenience performance of the device.

[0043] To improve the general performance of the device, the side plate 29 is slidably connected inside the frame of the cutting platform 1. An adjustment groove 35 is provided in the front side of the cutting platform 1 relative to the front side of the side plate 29. The front side of the side plate 29 is fixedly connected with a T-shaped block 36 which penetrates through the adjustment groove 35. A bolt 37 is threadedly connected through the front side of the T-shaped block 36, and the side wall of the bolt 37 abuts against the outer wall of the cutting platform 1;

[0044] When cutting longer plates according to the cutting requirements of furniture customization, the bolt 37 can be unscrewed with a tool to relieve the extrusion of the bolt 37 on the outer wall of the cutting platform 1. Then the T-shaped block 36 can be pushed to slide in the adjustment groove 35 and drive the side plate 29 to move, so as to adjust the limiting position of the plate, so that the middle position of the cut plate after lengthening exceeds the top groove 5, ensuring that the top block 6 can lift one end of the other three plates. It should be noted here that the length of the upper groove 9 is the same as the length of the discharge port. So for short plates, the pushing block 11 needs to slide a certain distance before it can push the plate. Finally, after the adjustment is completed, the bolt 37 can be rotated in the reverse direction with a tool to squeeze the outer wall of the cutting platform 1.

[0045] The above shows and describes the basic principle, main features and advantages of the present invention.

[0046] Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, various changes and improvements will occur to the present invention, and these changes and improvements all fall within the scope of the present invention claimed.
