Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to a sheet metal unloading and stacking device. Background Technology

[0002] In the furniture manufacturing industry, it is often necessary to cut large areas of boards into the required shapes and specifications, which is called material preparation. After passing through the material preparation machine, the boards are broken down into multiple smaller boards. The larger board, composed of these smaller boards, is then pushed onto the loading platform by the material preparation machine's pushing mechanism. At this point, workers manually move the boards to designated locations for stacking. During this process, the smaller boards become scattered and need to be reassembled and stacked, which is cumbersome and wastes manpower.

[0003] Therefore, a technical solution is needed to address the problem that workers need to manually stack the boards after cutting, which is cumbersome and wastes manpower. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problem that in the prior art, after the boards are cut, workers need to manually stack them, which is cumbersome and wastes manpower, and to provide a board cutting and stacking device.

[0005] In a first aspect, this utility model provides a sheet metal unloading and stacking device, including a moving mechanism, a blocking mechanism, and a stacking mechanism.

[0006] The moving mechanism includes a track assembly, on which a material rack is movably mounted, and a material carrier plate is mounted on the material rack. The material rack can drive the material carrier plate to move above the stacking mechanism.

[0007] Material blocking mechanism: The material blocking mechanism includes a support frame, a fixed frame is provided on the support frame, a lifting frame is connected to the fixed frame, the lifting frame is located above the material stacking mechanism, the lifting frame is provided with a limiting component, the limiting component includes a first push rod assembly and a second push rod assembly, the first push rod assembly and the second push rod assembly are provided on both sides of the lifting frame, the first push rod assembly and the second push rod assembly can move relative to each other to abut against the plate on the material carrier plate;

[0008] Stacking mechanism: The stacking mechanism includes a lifting assembly, and the lifting assembly is provided with a support platform for placing the plates.

[0009] This utility model discloses a sheet metal unloading and stacking device. In use, a moving mechanism is installed on the discharge side of the sheet metal unloading machine. After the unloading process, the sheet metal is pushed onto the carrier plate by the unloading machine's pushing mechanism. The carrier plate is moved along the track assembly by the material rack to above the stacking mechanism. At this time, the lifting frame in the blocking mechanism descends to the position of the carrier plate. The first and second push rod assemblies on the lifting frame limit the sheet metal on the carrier plate. Then, the material rack moves the carrier plate to the side of the unloading machine, thereby pulling out the carrier plate and causing the sheet metal on the carrier plate to fall onto the support platform below. Finally, the lifting assembly lowers the support platform and the sheet metal on the support platform by the thickness of the sheet metal, so that the sheet metal on the support platform and the carrier plate maintain a suitable height difference, preventing the sheet metal from scattering during the fall. This process is repeated to complete the automatic stacking of the unloaded sheet metal.

[0010] Preferably, the track assembly includes two tracks arranged opposite each other, the material rack includes two columns, the material carrier plate is connected between the two columns, and the bottom of the column is provided with a traveling component for driving the column to move. The traveling component includes a roller assembly and a motor. The roller assembly cooperates with the track, and the motor is used to drive the roller assembly to move along the track.

[0011] One end of the track extends to both sides of the discharge end of the feeder, and the other end extends to both sides of the stacking mechanism. After the loading plate receives the finished sheet material, the motor drives the roller assembly to run, thereby driving the loading plate between the two columns to run along the track to the top of the stacking mechanism, realizing the transportation process of the sheet material from the discharge end of the feeder to the stacking mechanism.

[0012] Preferably, a crossbar is provided between the two columns, and a hanging mechanism is provided on the crossbar. The hanging mechanism includes a vertical cylinder connected to the crossbar. The telescopic end of the vertical cylinder is connected to a slide cylinder. The vertical cylinder is used to drive the slide cylinder to move up and down. The telescopic end of the slide cylinder is connected to a support plate. The slide cylinder is used to drive the support plate to move laterally into or out of the bottom of the material carrier plate.

[0013] The specifications of the cut sheets vary, and the corresponding carrier plates used to load the sheets are also designed with different specifications. When the width of the carrier plate is too large, and considering weight and cost, the thickness of the carrier plate cannot be set too thick. Therefore, the middle of the carrier plate located between the two columns will sink. The sinking of the middle of the carrier plate can easily cause the sheets on the carrier plate to scatter. In this solution, a crossbar is added between the two columns, and a hanging mechanism is installed on the crossbar. In the hanging mechanism, a vertical cylinder extends the slide cylinder and the support plate connected to the slide cylinder to the height of the carrier plate. Then, the slide cylinder drives the support plate to extend under the carrier plate, and the vertical cylinder drives the support plate to abut against the bottom surface of the carrier plate, thereby supporting the middle of the carrier plate and reducing the sinking phenomenon in the middle of the carrier plate, thus preventing the cut sheets on the carrier plate from scattering.

[0014] Preferably, the first push rod assembly includes a first cylinder, which is connected to the lifting frame. The telescopic end of the first cylinder is connected to a first push rod, and the first cylinder is used to drive the first push rod to move horizontally.

[0015] The extension and retraction of the first cylinder drives the first push rod connected to the first cylinder to move horizontally, thereby limiting the plate between the first push rod assembly and the second push rod assembly.

[0016] Preferably, the second push rod assembly includes a second cylinder, which is connected to the lifting frame. The telescopic end of the second cylinder is connected to a second push rod, and the second cylinder is used to drive the second push rod to move horizontally.

[0017] The extension and retraction of the second cylinder drives the second push rod connected to the second cylinder to move horizontally, thereby limiting the plate between the first push rod assembly and the second push rod assembly.

[0018] Preferably, the lifting frame is provided with a second guide hole, and a second guide rod is provided in the second guide hole. The second guide rod passes through the second guide hole and is connected to the second push rod.

[0019] During the horizontal movement of the second push rod, the second guide rod moves along the axial direction of the second guide hole on the lifting frame, which guides the horizontal movement of the second push rod and prevents the second push rod from tilting or getting stuck during its movement.

[0020] Preferably, a cylinder stroke control mechanism is provided on one side of the lifting frame. The cylinder stroke control mechanism includes a mounting plate, a magnet and several Hall elements. The mounting plate is connected to the lifting frame and is arranged above the second guide rod along the length direction of the second guide rod. The several Hall elements are arranged along the length direction of the mounting plate, and the magnet is arranged on the second guide rod.

[0021] During the operation of the second push rod, the second guide rod will also move along the axial direction of the second guide hole. When the magnet of the second guide rod passes through the Hall element on the mounting plate in sequence, the corresponding Hall element senses the magnet and sends a signal to the control center to control the stroke of the second push rod, thereby adapting to the limit of different width plates.

[0022] Preferably, the limiting component further includes a third push rod assembly, which includes a third cylinder. The third cylinder is connected to the side of the lifting frame near the material rack. The telescopic end of the third cylinder is connected to a third push rod, and the third cylinder is used to drive the third push rod to move horizontally.

[0023] When the material carrier plate moves above the stacking mechanism, the lifting frame in the baffle mechanism descends to the position of the material carrier plate. The third cylinder connected to the lifting frame drives the third push rod to abut against the end of the plate near the unloading machine, thereby preventing the plate from being pulled out by the friction force of the material carrier plate during the extraction process, and further reducing the possibility of the plate scattering.

[0024] Preferably, the limiting component further includes a stop lever assembly, the stop lever assembly including a fourth cylinder, the fourth cylinder being connected to the side of the fixing frame away from the third push rod assembly, the telescopic end of the fourth cylinder being connected to a stop lever, and the fourth cylinder being used to drive the stop lever to move vertically.

[0025] When the material carrier plate moves above the stacking mechanism, the fourth cylinder drives the stop bar to move downward and fall onto the material carrier plate, blocking the front end of the material on the material carrier plate, thereby limiting the material on all four sides, preventing the material from slipping and reducing the possibility of the material scattering.

[0026] Preferably, the stacking mechanism further includes a photoelectric sensor and a control unit. The photoelectric sensor and the lifting assembly are electrically connected to the control unit. The photoelectric sensor is used to monitor the height of the plate on the support platform, and the control unit is used to control the lifting assembly to raise or lower according to the photoelectric sensor signal.

[0027] The height of the sheet material on the support platform is monitored by photoelectric sensors. After a new sheet material falls onto the support platform, the total height of the sheet material increases. The photoelectric sensors transmit signals to the control unit, which controls the lifting assembly to descend, thereby reducing the height of the top surface of the sheet material on the support platform. This ensures that the top surface of the sheet material on the support platform is always within a certain height range from the load plate. On the one hand, this ensures that the load plate can smoothly reach the top of the stacking mechanism, and on the other hand, it prevents the sheet material from scattering during the process of falling from the load plate onto the support platform.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] 1. This utility model provides a sheet material unloading and stacking device. By setting a moving mechanism with a material carrier plate, the unloaded material is transported to the stacking mechanism. Then, the material blocking mechanism limits the sheet material on the material carrier plate. As the moving mechanism moves away from the material carrier plate, the sheet material can fall into the stacking mechanism, realizing automatic stacking of the unloaded sheet material, improving production efficiency and reducing manual input.

[0030] 2. This utility model provides a sheet material unloading and stacking device, which limits the sheet material from both sides through the first push rod assembly and the second push rod assembly, so that the sheet material can maintain its original shape during the process of falling from the carrier plate onto the support platform and is not easy to scatter.

[0031] 3. This utility model provides a sheet material unloading and stacking device. By setting a lifting component at the bottom of the support platform used for stacking, after the sheet material falls onto the support platform, the height of the top surface of the sheet material can be adjusted by the lifting component to maintain a suitable height difference between the sheet material on the support platform and the load plate, so that the sheet material does not scatter during the falling process.

[0053] Example 1

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, a sheet metal unloading and stacking device includes a moving mechanism 2, a blocking mechanism 3, and a stacking mechanism 4.

[0055] Moving mechanism 2: includes a track assembly 21, on which a material rack 22 is movably mounted, and a material carrier plate 221 is mounted on the material rack 22. The material rack 22 can drive the material carrier plate 221 to move above the stacking mechanism 4.

[0056] Material blocking mechanism 3: The material blocking mechanism 3 includes a support frame 31, a fixed frame 32 is provided on the support frame 31, and a lifting frame 33 is connected to the fixed frame 32. The lifting frame 33 is located above the material stacking mechanism 4. The lifting frame 33 is provided with a limiting component 35. The limiting component 35 includes a first push rod assembly 351 and a second push rod assembly 352. The first push rod assembly 351 and the second push rod assembly 352 are provided on both sides of the lifting frame 33. The first push rod assembly 351 and the second push rod assembly 352 can move relative to each other to abut against the plate 7 on the material carrier plate 221.

[0057] Stacking mechanism 4: The stacking mechanism 4 includes a lifting component 41, and the lifting component 41 is provided with a support platform 42 for placing the plate 7.

[0058] In use, the moving mechanism 2 is installed on the discharge side of the sheet metal unloading machine 1. After the unloading process, the sheet metal 7 is pushed onto the carrying plate 221 by the pushing mechanism of the unloading machine 1. The carrying plate 221 is moved along the track assembly 21 by the material rack 22 to above the stacking mechanism 4. At this time, the lifting frame 33 in the blocking mechanism 3 descends to the position of the carrying plate 221. The first push rod assembly 351 and the second push rod assembly 352 on the lifting frame 33 limit the sheet metal 7 on the carrying plate 221. Then, the material is pushed onto the carrying plate 221 by the material rack 221. The frame 22 moves the carrier plate 221 to the side of the feeder 1, thereby pulling out the carrier plate 221 and letting the board 7 on the carrier plate 221 fall onto the support platform 42 below. Finally, the lifting component 41 drives the support platform 42 and the board 7 on the support platform 42 to drop by the thickness of one board 7, so that the board 7 on the ground of the support platform 42 and the carrier plate 221 maintain a suitable height difference, so that the board 7 will not be scattered during the falling process. This process is repeated to complete the automatic stacking of the board 7 after it is unloaded.

[0059] Track assembly 21: Track assembly 21 includes two tracks arranged opposite each other, one end of which extends to both sides of the discharge end of the feeder 1, and the other end of which extends to both sides of the stacking mechanism 4.

[0060] Material rack 22: The material rack 22 includes two columns 222. The material carrier plate 221 is connected between the two columns 222. The bottom of the column 222 is provided with a traveling component 23 for driving the column 222 to move. The traveling component 23 includes a roller assembly 232 and a motor 231. The roller assembly 232 cooperates with the track. The motor 231 is used to drive the roller assembly 232 to move along the track. After the material carrier plate 221 receives the unloaded plate 7, the motor 231 drives the roller assembly 232 to run, thereby driving the material carrier plate 221 between the two columns 222 to run along the track to the top of the stacking mechanism 4, realizing the transportation process of the plate 7 from the discharge end of the unloading machine 1 to the stacking mechanism 4.

[0061] Support frame 31: Support frame 31 includes two support columns 311. A base plate 312 is provided at the bottom of the support column 311. A diagonal brace 313 is connected between the support plate 53 and the support column 311. A transverse reinforcing bar 314 is provided between the two columns 222 to connect the two support columns 311 into one unit. The two sides of the fixing frame 32 are respectively connected to the two support columns 311. A reinforcing rib plate 315 is connected between the fixing frame 32 and the support column 311.

[0062] Fixed frame 32: The fixed frame 32 is rectangular in shape, and multiple main cylinders 34 are arranged around the fixed frame 32. The telescopic ends of the main cylinders 34 are connected to the lifting frame 33, and the lifting frame 33 is moved up and down by the main cylinders 34.

[0063] First push rod assembly 351: The first push rod assembly 351 includes a first cylinder 3511, which is connected to the lifting frame 33. The telescopic end of the first cylinder 3511 is connected to a first push rod 3512. The first cylinder 3511 is used to drive the first push rod 3512 to move horizontally. The lifting frame 33 is provided with a first guide hole, and a first guide rod 3513 is provided in the first guide hole. The first guide rod 3513 passes through the first guide hole and is connected to the first push rod 3512.

[0064] Second push rod assembly 352: The second push rod assembly 352 includes a second cylinder 3521, which is connected to the lifting frame 33. The telescopic end of the second cylinder 3521 is connected to a second push rod 3522. The second cylinder 3521 is used to drive the second push rod 3522 to move horizontally. The lifting frame 33 is provided with a second guide hole, and a second guide rod 3523 is provided in the second guide hole. The second guide rod 3523 passes through the second guide hole and is connected to the second push rod 3522.

[0065] Stacking Mechanism 4: The stacking mechanism 4 also includes a photoelectric sensor and a control unit. The photoelectric sensor and the lifting assembly 41 are electrically connected to the control unit. A mounting rod 43 is provided on one side of the support platform 42. The photoelectric sensor is mounted on the mounting rod and is used to monitor the height of the plate 7 on the support platform 42. The control unit is used to control the lifting assembly 41 to raise or lower according to the photoelectric sensor signal. By monitoring the height of the plate 7 on the support platform 42 through the photoelectric sensor, after a new plate 7 falls onto the support platform 42, the total height of the plate 7 increases. The photoelectric sensor transmits the signal to the control unit, and the control unit controls the lifting assembly 41 to descend, thereby reducing the height of the top surface of the plate 7 on the support platform 42. This ensures that the top surface of the plate 7 on the support platform 42 is always within a certain height range from the carrying plate 221. On the one hand, this ensures that the carrying plate 221 can smoothly reach the top of the stacking mechanism 4. On the other hand, it prevents the plate 7 from scattering during the process of falling from the carrying plate 221 onto the support platform 42.

[0066] Example 2

[0067] like Figure 1 , Figure 3 , Figure 5 and Figure 8 As shown, in this embodiment, the difference from embodiment 1 is that, in order to accommodate the limiting of plates 7 of different widths, a cylinder stroke control mechanism 6 is provided on at least one side of the lifting frame 33. The cylinder stroke control mechanism 6 includes a mounting plate 61, a magnet 62 and several Hall elements 63.

[0068] Specifically, an mounting plate 61 is provided on the right side of the lifting frame 33. The mounting plate 61 is positioned above the second guide rod 3523 along the length direction of the second guide rod 3523. Hall elements 63 are arranged on the mounting plate 61 along the length direction of the mounting plate 61. Magnets 62 are located at the end of the second guide rod 3523. During the operation of the second push rod 3522, the second guide rod 3523 will also move along the axial direction of the second guide hole. When the magnets 62 of the second guide rod 3523 pass through the Hall elements 63 on the mounting plate 61 in sequence, the corresponding Hall elements 63 sense the magnets 62 and send a signal to the control center to control the stroke of the second push rod 3522, thereby adapting to the limit of different width plates 7.

[0069] Example 3

[0070] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 9As shown, in this embodiment, the difference from Embodiment 1 is that there is a crossbar 223 between the two columns 222. The crossbar 223 is provided with a hanging mechanism 5. The hanging mechanism 5 includes a vertical cylinder 51 connected to the crossbar 223. The telescopic end of the vertical cylinder 51 is connected to a slide cylinder 52. The vertical cylinder 51 is used to drive the slide cylinder 52 to move up and down. The telescopic end of the slide cylinder 52 is connected to a support plate 53. The slide cylinder 52 is used to drive the support plate 53 to move laterally into or out of the bottom of the material carrier plate 221.

[0071] The sheet metal 7 used for cutting varies in size, and the corresponding carrier plate 221 used to load the sheet metal 7 will also be designed with different sizes. When the width of the carrier plate 221 is too large (i.e., cutting laterally), and considering weight and cost, the thickness of the carrier plate 221 cannot be set too thick. Therefore, the middle part of the carrier plate 221 located between the two columns 222 will sink. The sinking of the middle part of the carrier plate 221 can easily cause the sheet metal 7 on the carrier plate 221 to scatter. In this embodiment, a crossbar 223 is added between the two columns 222. The hanging mechanism 5 is installed via the crossbar 223. In the hanging mechanism 5, the vertical cylinder 51 extends the slide cylinder 52 and the support plate 53 connected to the slide cylinder 52 to the height of the material plate 221. Then, the slide cylinder 52 drives the support plate 53 to extend under the material plate 221. The vertical cylinder 51 then drives the support plate 53 to abut against the bottom surface of the material plate 221, thereby providing support for the middle part of the material plate 221 and reducing the sinking phenomenon in the middle part of the material plate 221, thus preventing the cut material on the material plate 221 from scattering.

[0072] Furthermore, the fixed frame 32 is provided with a first clearance notch on both the side close to the unloading machine 1 and the side away from the unloading machine 1, and the lifting frame 33 is provided with a second clearance notch on the side close to the unloading machine 1, and an opening is provided on the side of the lifting frame 33 away from the unloading machine 1, so that the holding mechanism 5 will not interfere with the fixed frame 32 and the lifting frame 33 during the operation of the moving mechanism 2.

[0073] Furthermore, the limiting component 35 also includes a third push rod assembly 353, which includes two third push rods 3531, located on both sides of the first clearance notch. Each third push rod 3531 is connected to a third cylinder 3532, which drives the third push rods 3531 to move horizontally. The third cylinder 3532 is connected to the lifting frame 33. A third guide hole is provided on the side of the lifting frame 33 closest to the material rack 22, and a third guide rod 3533 is fitted into the third guide hole. 3533 passes through the third guide hole and is connected to the third push rod 3531. When the material plate 221 moves to the top of the stacking mechanism 4, the lifting frame 33 in the blocking mechanism 3 descends to the position of the material plate 221. The third cylinder 3532 connected to the lifting frame 33 drives the third push rod 3531 to abut against the end of the plate 7 near the unloading machine 1, thereby preventing the plate 7 from being pulled out by the friction force of the material plate 221 during the extraction of the material plate 221, and further reducing the possibility of the plate 7 scattering.

[0074] Furthermore, the limiting component 35 also includes a stop lever assembly 354, which includes two stop levers 3541 located on both sides of the first clearance notch. The stop levers 3541 are connected to a fourth cylinder 3542, which is used to drive the stop levers 3541 to move vertically. The fourth cylinder 3542 is connected to a fixed frame 32. A fourth guide hole is provided on the side of the fixed frame 32 away from the third push rod assembly 353. A fourth guide rod is provided in the fourth guide hole, and the fourth guide rod passes through the fourth guide hole and is connected to the stop levers 3541.

[0075] Example 4

[0076] like Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in this embodiment, the difference from Embodiment 1 is that the fixed frame 32 includes a first fixed frame 321 and a second fixed frame 322, and the lifting frame 33 includes a first lifting frame 331 and a second lifting frame 332. The first fixed frame 321 is disposed on the side of the support frame 31 close to the unloading machine 1, and the second fixed frame 322 is disposed on the side of the support frame 31 away from the unloading machine 1. The first lifting frame 331 is connected to the first fixed frame 32, and the second lifting frame 332 is connected to the second fixed frame 322.

[0077] In this embodiment, when the length of the cutting plate 7 is relatively long (i.e., longitudinal cutting), the length of the corresponding fixing frame 32 and lifting frame 33 used to limit the plate 7 will also be relatively long. Therefore, the fixing frame 32 and lifting frame 33 are set as two parts and installed on both sides of the support frame 31 respectively, thereby improving the structural stability of the entire material blocking mechanism 3.

[0078] Furthermore, the first push rod assembly 351 includes two first push rods 3512, which are located on both sides of the support frame 31 respectively. Each first push rod 3512 is connected to a first cylinder 3511. One first cylinder 3511 is connected to the first lifting frame, and the other first cylinder 3511 is connected to the second lifting frame 33.

[0079] Furthermore, the second push rod assembly 352 includes two second push rods 3522, which are located on both sides of the support frame 31 respectively. Each second push rod 3522 is connected to a second cylinder 3521. One second cylinder 3521 is connected to the first lifting frame 331, and the other second cylinder 3521 is connected to the second lifting frame 332.

[0080] Furthermore, the limiting component 35 also includes a third push rod assembly 353, which includes a third cylinder 3532. The third cylinder 3532 is connected to the side of the first lifting frame 331 near the unloading machine 1. The telescopic end of the third cylinder 3532 is connected to the third push rod 3531. The third cylinder 3532 is used to drive the third push rod 3531 to move horizontally.

[0081] Furthermore, the limiting component 35 also includes a fourth push rod assembly 355, which includes a fifth cylinder 3552. The fifth cylinder 3552 is connected to the side of the second lifting frame 332 away from the unloading machine 1. The telescopic end of the fifth cylinder 3552 is connected to the fourth push rod 3551. The fifth cylinder 3552 is used to drive the fourth push rod 3551 to move horizontally.

[0082] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
