Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine equipment technology, specifically to a feeding device. Background Technology

[0002] Existing laser cutting punch presses generally use manual or automatic unloading mechanisms for unloading. The former involves manual feeding or picking, which is relatively inefficient. When the latter is used for automatic unloading, the existing unloading mechanism can only perform stacking unloading or single sheet unloading, requiring the configuration of separate stacking unloading production lines or single sheet unloading production lines. This not only requires more equipment and occupies more space, but also has high costs, which is not conducive to improving production efficiency. Utility Model Content

[0003] In order to overcome the defects in the prior art, this utility model provides a feeding device that can switch feeding methods, is compatible with single sheet feeding or stacked feeding, and improves production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model discloses a feeding device, which is connected to the punch press of a laser cutting machine, comprising:

[0006] The guide rail includes a first guide rail, a second guide rail, and a third guide rail disposed at different heights, wherein the first guide rail is higher than the third guide rail, and the second guide rail is located between the first guide rail and the third guide rail;

[0007] The first tray is connected to the first guide rail and can move along the first guide rail to a preset position;

[0008] The second tray is connected to the second guide rail and can move along the second guide rail to a preset position below it;

[0009] The third tray is connected to the third guide rail and can move along the third guide rail to a position below a preset location. The third tray is also liftable.

[0010] A baffle is located above a preset position and on the side of the preset position close to the punch press. The baffle is adjustable in height.

[0011] The above technical solution sets up multiple pallets at different heights in the same feeding device. The board material is transported from the first pallet to the second pallet to realize single-sheet conveying. The board material is also transported from the first pallet to the third pallet to realize stacked conveying. This can not only improve the working efficiency of the equipment, but also automatically switch the feeding method to meet the needs of different production lines and improve production efficiency.

[0012] Furthermore, it also includes a sheet material transfer area, which is divided into a first area, a second area, and a third area along the sheet material transfer direction. The first guide rail is located in the first area and the second area, and the second guide rail and the third guide rail are both located in the second area and the third area. The first pallet moves along the first guide rail in the first area and the second area, the second pallet moves along the second guide rail, and the third pallet moves along the third guide rail in the second area and the third area.

[0013] Furthermore, the third tray includes a first platform, a second platform, and a lifting component located between the first and second platforms. The lifting component is driven by a first cylinder, which in turn moves the first platform up and down. The first cylinder is a hydraulic cylinder, and the lifting component is connected to both the first and second platforms, achieving lifting and lowering through pressure transmission from the hydraulic cylinder.

[0014] Furthermore, the second platform is connected to rollers on the side opposite to the lifting component, and these rollers slide along the third guide rail. This causes the third pallet to move between the second and third zones, receiving and transporting sheet metal.

[0015] Furthermore, the first guide rail is provided with a mounting bracket, and a mounting plate is connected to the mounting bracket. A second cylinder is provided on the mounting plate, and the second cylinder is connected to the baffle. After the first pallet moves to a preset position, the baffle is driven to descend by the second cylinder, so as to block the movement of the board material on the first pallet when the first pallet returns to the first area, causing the board material to fall to the second pallet or the third pallet.

[0016] Furthermore, a first slider is provided on the first guide rail, and the first slider is connected to the first tray. A second slider is provided on the second guide rail, and the second slider is connected to the second tray. When the slider slides along the guide rail, it drives the tray to move.

[0017] Furthermore, the second tray is provided with a first stop, and the third tray is provided with a second stop. The first stop is located on the edge of the second tray on the side relatively away from the baffle, and the second stop is located on the edge of the third tray on the side relatively away from the baffle, to prevent the sheet material from slipping.

[0018] Furthermore, the second guide rail is provided with a first switch and a second switch. The first switch is located on the side of the second zone away from the baffle, and the second switch is located on the side of the third zone away from the baffle. The first and second switches are used to detect whether the tray has moved to a preset position.

[0019] Furthermore, it also includes a bracket, which includes a support column arranged in a vertical direction and a support rod arranged in a sheet material moving direction. The support rod includes a first support rod and a second support rod connected to the support column. The first support rod is located above the second support rod. The first guide rail is connected to the first support rod, and the second guide rail is connected to the second support rod.

[0020] Furthermore, the first tray and the second tray are provided with reinforcing ribs on the side opposite to the baffle.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] This application, by setting multiple trays of different heights in the same feeding device, can automatically switch feeding methods and is compatible with single-sheet feeding or stacked feeding in the same device, which can meet the needs of different production lines, improve space utilization, and increase production efficiency.

[0033] Reference Figures 1-4This application provides a feeding device connected to a punch press for transporting sheet metal. The device includes a guide rail and a pallet connected to the guide rail. The pallet supports the sheet metal, and the guide rail is used to move the pallet. The guide rail includes a first guide rail 1, a second guide rail 2, and a third guide rail 3 at different heights. The first guide rail 1 is higher than the third guide rail 3, and the second guide rail 2 is located between the first guide rail 1 and the third guide rail 3. The pallet includes a first pallet 4, a second pallet 5, and a third pallet 6. The first pallet 4 is connected to the first guide rail 1 and can move along the first guide rail 1 to a preset position. The second pallet 5 is connected to the first guide rail 1, and the third pallet 6 is moved along the first guide rail 1. The first tray 4 is connected to the second guide rail 2 and can move along the second guide rail 2 to a preset position below it. The third tray 6 is connected to the third guide rail 3 and can move along the third guide rail 3 to a preset position below it. The third tray 6 is liftable and is used for stacking sheet metal. It also includes a baffle 7, which is located above the preset position and on the side of the preset position closer to the punch. The baffle 7 is liftable and is positioned so that when it is lowered, the sheet metal is all located on the side of the baffle 7 away from the punch, thereby preventing the sheet metal on the first tray 4 from moving and automatically transferring the sheet metal on the first tray 4 to the second tray 5 or the third tray 6. The preset position is a pre-set position for transferring the sheet metal on the first tray 4 to other trays.

[0034] With the above structure, the feeding device in this embodiment can switch feeding methods according to needs, realize single sheet conveying and stacked conveying of sheet metal, meet different production line needs, reduce costs, and improve space utilization and production efficiency.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the unloading device in this embodiment includes a support frame. The support frame includes a plurality of vertically arranged support columns 24 and a horizontally arranged support rod. The support rod extends along the sheet metal transfer direction. Each support rod includes a first support rod 25 and a second support rod 26 connected to the support columns 24. The first support rod 25 is located above the second support rod 26. A first guide rail 1 is connected to the first support rod 25, and a second guide rail 2 is connected to the second support rod 26. The sheet metal transfer direction is... Figure 2 The direction indicated by the middle arrow.

[0036] The feeding device is provided with a sheet material transfer area, which is divided into a first zone 8, a second zone 9 and a third zone 10 along the sheet material transfer direction. A first guide rail 1 and a first support rod 25 are located between the first zone 8 and the second zone 9. A second guide rail 2, a third guide rail 3 and a second support rod 26 are located between the second zone 9 and the third zone 10. A first pallet 4 moves along the first guide rail 1 within the first zone 8 and the second zone 9 to transport the formed sheet material to the second pallet 5 or the third pallet 6. The second pallet 5 moves along the second guide rail 2 and the third pallet 6 moves along the third guide rail 3 within the second zone 9 and the third zone 10. The second pallet 5 is used to realize the single sheet material transport and the third pallet 6 is used to realize the stacked transport of the sheet material. In the embodiment of this application, the preset position is located within the second zone 9.

[0037] The first guide rail 1 is provided with a first slider 18, which is connected to the first tray 4. The second guide rail 2 is provided with a second slider 19, which is connected to the second tray 5. When the slider slides, it drives the tray to move.

[0038] The third tray 6 includes a first platform 11, a second platform 12, and a lifting component 13 located between the first platform 11 and the second platform 12. The lifting component 13 is driven by a first cylinder (not shown in the figure), which raises and lowers the first platform 11. The first cylinder is a hydraulic cylinder, which realizes the lifting function of the lifting component 13 through pressure transmission. The lifting component 13 can be configured in various structures, such as... Figure 3 As shown in the illustration, this application presents an embodiment of a scissor lift structure, in which the piston rod of a hydraulic cylinder reciprocates, driving the scissor lift structure to rise or fall. Figure 4 As shown, the second platform 12 is connected to a roller 14 on the side opposite to the lifting component 13, and the roller 14 slides along the third guide rail 3.

[0039] During operation, the unloading device is connected to the punch press of the laser cutting machine. The punch press, through its own feeding device and clamps, transports the formed sheet metal to the first tray 4. The first tray 4 is connected to a motor (not shown in the figure). The motor drives the first tray 4 to move along the first guide rail 1 above the second tray 5. During the process of the first tray 4 returning to the first zone 8, the formed sheet metal is transferred to the second tray 5 or the third tray 6 through the baffle 7. Because the clamps of the punch press have a relatively fast conveying speed, the conveying of the next sheet metal begins immediately after one sheet metal is delivered. The second tray 5 and the third tray 6 can be coordinated with the speed of the clamps, which can both switch the unloading method and improve the production efficiency of the equipment.

[0040] baffle 7 can be raised and lowered, such as Figure 2As shown, a mounting bracket 15 is provided on the first guide rail 1, and a mounting plate 16 is connected to the mounting bracket 15. A second cylinder 17 is detachably provided on the mounting plate 16, and the second cylinder 17 is connected to the baffle 7. In the embodiments of this application, the baffle 7 has a long strip-shaped plate structure that extends along the width direction of the feeding device. The length and width of the baffle 7 are set according to the actual situation.

[0041] When a single sheet of material needs to be transferred, the second pallet 5 is positioned below a preset location within the second zone 9, waiting for the material. After the first pallet 4 moves to the preset location, the second cylinder 17 pushes the baffle 7 down to a position that can block the material on the first pallet 4. As the first pallet 4 returns to the first zone 8, the material on the first pallet 4 is blocked by the baffle 7 and cannot move with the first pallet 4, thus falling onto the second pallet 5. The second pallet 5 then moves to the third zone 10 via the second guide rail 2, thus realizing the single-sheet conveying of the material.

[0042] When stacked transfer of sheet metal is required, the second pallet 5 is moved out of the second zone 9, and the third pallet 6 is moved from the third zone 10 to below the preset position in the second zone 9. First, the first platform 11 is raised to a position at least the same height as the second pallet 5 by the lifting component 13. The process of transferring the sheet metal from the first pallet 4 to the third pallet 6 is as described above and will not be repeated here. After the sheet metal on the third pallet 6 is stacked to the preset height, the third pallet 6 returns to the third zone 10, and the second pallet 5 returns to the second zone 9, thus realizing the stacked transfer of sheet metal.

[0043] The preset height is as follows: when the third pallet 6 descends to the lowest point, the boards stacked on the third pallet 6 do not contact the second pallet 5 when the third pallet 6 returns to the third zone 10 and the second pallet 5 returns to the second zone 9.

[0044] To prevent the sheet metal from falling, a first stop 20 is provided on the side of the second pallet 5 away from the baffle 7, and a second stop 21 is provided on the side of the third pallet 6 away from the baffle 7.

[0045] In order to detect whether the first tray 4, the second tray 5 and the third tray 6 have moved to the preset position, the second guide rail 2 is provided with a first switch 22 and a second switch 23. The first switch 22 is located in the second zone 9, on the side of the second zone 9 away from the baffle 7. The second switch 23 is located in the third zone 10, on the side of the third zone 10 away from the baffle 7.

[0046] To enhance the structural strength of the first tray 4 and the second tray 5, such as Figure 4 As shown, the first tray 4 and the second tray 5 are provided with reinforcing ribs 27 on the side opposite to the baffle 7.

[0047] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
