Description

Technical Field

[0001] The invention relates to the field of plate processing, and in particular to a plate blanking and stacking device. Background Art

[0002] In the furniture processing industry, it is often necessary to cut large-area boards into required shapes and specifications, which is called blanking. After passing through the blanking machine, the board becomes multiple small boards, and the large board composed of multiple small boards is pushed to the loading platform by the pushing mechanism of the blanking machine. At this time, the workers will manually move the boards to the designated location for stacking. In this process, the small boards will become scattered and need to be reassembled and stacked, which is cumbersome and wastes manpower.

[0003] Therefore, a technical solution is currently needed to solve the technical problem that workers need to manually stack the plates after cutting, which is cumbersome and wastes manpower. Summary of the invention

[0004] The purpose of the present invention is to overcome the technical problem in the prior art that workers need to manually stack the plates after unloading, which is cumbersome and wastes manpower, and to provide a plate unloading and stacking device.

[0005] In a first aspect, the present invention provides a plate material unloading and stacking device, comprising a moving mechanism, a material blocking mechanism and a material stacking mechanism. The moving mechanism comprises a track assembly, on which a material rack is movably provided, on which a material loading plate is provided, and the material rack can drive the material loading plate to move above the stacking mechanism; Material blocking mechanism: the material blocking mechanism comprises a support frame, a fixed frame is arranged on the support frame, a lifting frame is connected to the fixed frame, the lifting frame is located above the stacking mechanism, the lifting frame is provided with a limiting component, the limiting component comprises a first push rod assembly and a second push rod assembly, the first push rod assembly and the second push rod assembly are arranged on both sides of the lifting frame, and the first push rod assembly and the second push rod assembly can move relative to each other to abut against the plate on the loading plate; Stacking mechanism: The stacking mechanism includes a lifting assembly, and the lifting assembly is provided with a support platform for placing the plate.

[0006] The present invention relates to a plate unloading and stacking device. When in use, the moving mechanism is installed on the discharging side of the plate unloading machine. After the plate has passed the unloading process, the plate is pushed onto the loading plate by the pushing mechanism of the unloading machine, and the loading plate is driven by the material rack to move along the track assembly to above the stacking mechanism. At this time, the lifting frame in the material blocking mechanism descends to the position of the loading plate, and the first push rod assembly and the second push rod assembly on the lifting frame limit the plate on the loading plate. Subsequently, the loading plate is driven by the material rack to move toward one side of the lower feeder, thereby pulling out the loading plate, so that the plate on the loading plate falls onto the supporting platform below, and finally, the supporting platform and the plate on the supporting platform are driven to descend to a height of the plate thickness by the lifting assembly, so that the plate on the ground of the support platform and the loading plate maintain a suitable height difference, so that the plate will not be scattered during the falling process. This process is repeated to complete the automatic stacking of the plate after unloading.

[0007] Preferably, the track assembly includes two relatively arranged tracks, the material rack includes two columns, the loading plate is connected between the two columns, and a traveling component for driving the column to move is provided at the bottom of the column, 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.

[0008] One end of the track extends to both sides of the discharge end of the feeder, and the other end of the track extends to both sides of the stacking mechanism. After the loading plate receives the completed plate, 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 plate material from the discharge end of the feeder to the stacking mechanism.

[0009] Preferably, there is a cross bar between the two columns, and a hanging mechanism is provided on the cross bar, and the hanging mechanism includes a vertical cylinder connected to the cross bar, and the telescopic end of the vertical cylinder is connected to a slide cylinder, and the vertical cylinder is used to drive the slide cylinder to move up and down, and the telescopic end of the slide cylinder is connected to a support plate, and the slide cylinder is used to drive the support plate to move laterally in or out of the bottom of the loading plate.

[0010] The specifications of the unloading plates are different, and the corresponding loading plates for loading the plates will also be designed with different specifications. When the width of the loading plate is too large, the thickness of the loading plate cannot be set too thick due to weight and cost considerations. Therefore, the middle part of the loading plate between the two columns will sink. The sinking of the middle part of the loading plate will easily cause the plates on the loading plate to scatter. In this scheme, a cross bar is added between the two columns, and a hanging mechanism is installed through the cross bar. In the hanging mechanism, the slide cylinder and the support plate connected to the slide cylinder are extended to the height of the loading plate through the vertical cylinder, and then the support plate is driven by the slide cylinder to extend under the loading plate, and then the support plate is driven by the vertical cylinder to abut against the bottom surface of the loading plate, thereby forming support for the middle part of the loading plate to reduce the sinking phenomenon in the middle part of the loading plate, thereby avoiding the scattering of the cut plates on the loading plate.

[0011] Preferably, the first push rod assembly includes a first cylinder, the first cylinder is connected to the lifting frame, the telescopic end of the first cylinder is connected to the first push rod, and the first cylinder is used to drive the first push rod to move horizontally.

[0012] The telescopic movement 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.

[0013] Preferably, the second push rod assembly includes a second cylinder, the second cylinder is connected to the lifting frame, the telescopic end of the second cylinder is connected to the second push rod, and the second cylinder is used to drive the second push rod to move horizontally.

[0014] The telescopic movement 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.

[0015] Preferably, the lifting frame is provided with a second guide hole, the second guide hole is equipped with a second guide rod, and the second guide rod passes through the second guide hole and is connected to the second push rod.

[0016] 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, guiding the horizontal movement of the second push rod and avoiding tilting and jamming of the second push rod during movement.

[0017] Preferably, a cylinder stroke control mechanism is provided on one side of the lifting frame, and the cylinder stroke control mechanism includes a mounting plate, a magnet sheet and a plurality of 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. A plurality of the Hall elements are arranged along the length direction of the mounting plate, and the magnet sheet is arranged on the second guide rod.

[0018] During the operation of the second push rod, the second guide rod will also run along the axial direction of the second guide hole. When the magnet sheet of the second guide rod passes through the Hall element on the mounting plate in sequence, the corresponding Hall element will sense the magnet sheet and send a signal to the control center to control the stroke of the second push rod, thereby adapting to the limit of plates of different widths.

[0019] Preferably, the limiting component also includes a third push rod assembly, the third push rod assembly includes a third cylinder, the third cylinder is connected to the side of the lifting frame close to the material rack, the telescopic end of the third cylinder is connected to the third push rod, and the third cylinder is used to drive the third push rod to move horizontally.

[0020] When the loading plate moves to above the stacking mechanism, the lifting frame in the material blocking mechanism descends to the position of the loading plate, and the third cylinder connected to the lifting frame drives the third push rod to abut against the end of the plate close to the unloading machine, thereby preventing the plate from being carried out by the friction force of the loading plate during the pulling out process, which can further reduce the possibility of the plate being scattered.

[0021] Preferably, the limiting component also includes a shift rod assembly, the shift rod assembly includes a fourth cylinder, the fourth cylinder is connected to the side of the fixed frame away from the third push rod assembly, the telescopic end of the fourth cylinder is connected to the shift rod, and the fourth cylinder is used to drive the shift rod to move vertically.

[0022] When the loading plate moves to above the stacking mechanism, the fourth cylinder drives the gear rod to move downward and fall onto the loading plate, blocking the front end of the plate on the loading plate, thereby limiting the four sides of the material to prevent the plate from slipping and reducing the possibility of the plate being scattered.

[0023] Preferably, the stacking mechanism also includes a photoelectric sensor and a control unit, the photoelectric sensor and the lifting assembly are electrically connected to the control unit respectively, the photoelectric sensor is used to monitor the height of the plate on the support table, and the control unit is used to control the lifting assembly to rise or fall according to the photoelectric sensor signal.

[0024] The height of the plate on the support table is monitored by a photoelectric sensor. After a new plate falls onto the support table, the total height of the plate increases, and the photoelectric sensor transmits a signal to the control unit. The control unit controls the lifting assembly to descend, thereby lowering the height of the top surface of the plate on the support table, so that the height of the top surface of the plate on the support table is always maintained within a certain height range with the loading plate. On the one hand, it ensures that the loading plate can smoothly reach the top of the stacking mechanism, and on the other hand, it prevents the plates from being scattered when they fall from the loading plate to the support table.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a plate unloading and stacking device, which transports the unloaded materials to the stacking mechanism by setting a mobile mechanism with a loading plate, and then limits the plate on the loading plate by a blocking mechanism, so that when the mobile mechanism is taken away from the loading plate, the plate can fall onto the stacking mechanism, thereby realizing automatic stacking of the unloaded plates, improving production efficiency, and reducing labor input; 2. The present invention provides a plate material unloading and stacking device, which limits the plate from both sides of the plate through the first push rod assembly and the second push rod assembly, so that the plate can maintain its original shape when falling from the loading plate to the supporting platform, and is not easy to be scattered; 3. The present invention provides a plate material unloading and stacking device, which is configured with a lifting assembly at the bottom of a support platform for stacking materials. After the plates fall onto the support platform, the height of the top surface of the plates can be adjusted by the lifting assembly, so that the plates on the ground of the support platform and the loading plate maintain a suitable height difference, so that the plates will not be scattered during the falling process.

[0034] When in use, the mobile mechanism 2 is installed on the discharge side of the plate 7 feeder 1. After the plate 7 has passed the feeding process, it is pushed onto the loading plate 221 by the pushing mechanism of the feeder 1. The loading plate 221 is driven by the material rack 22 to move along the track assembly 21 to the top of the stacking mechanism 4. At this time, the lifting frame 33 in the material blocking mechanism 3 descends to the position of the loading plate 221. The first push rod assembly 351 and the second push rod assembly 352 on the lifting frame 33 limit the plate 7 on the loading plate 221. Then, the plate 7 is The rack 22 drives the loading plate 221 to move toward the side of the feeder 1, thereby pulling out the loading plate 221, allowing the plate 7 on the loading plate 221 to fall onto the support platform 42 below, and finally the lifting assembly 41 drives the support platform 42 and the plate 7 on the support platform 42 to drop to a height of the thickness of the plate 7, so that the plate 7 on the ground of the support platform 42 maintains a suitable height difference with the loading plate 221, so that the plate 7 will not be scattered during the falling process, and the process is repeated to complete the automatic stacking of the plate 7 after unloading.

[0035] Track assembly 21: The track assembly 21 includes two tracks arranged opposite to each other, one end of the track extends to both sides of the discharge end of the feeder 1 , and the other end of the track extends to both sides of the stacking mechanism 4 .

[0036] Material rack 22: The material rack 22 includes two columns 222, the loading plate 221 is connected between the two columns 222, and a traveling component 23 for driving the column 222 to move is arranged at the bottom of the column 222, and the traveling component 23 includes a roller assembly 232 and a motor 231, and the roller assembly 232 cooperates with the track, and the motor 231 is used to drive the roller assembly 232 to move along the track. After the loading plate 221 receives the plate 7 that has been unloaded, the roller assembly 232 is driven to run by the motor 231, thereby driving the loading plate 221 between the two columns 222 to run along the track to above the stacking mechanism 4, thereby realizing the transportation process of the plate 7 from the discharge end of the unloading machine 1 to the stacking mechanism 4.

[0037] Support frame 31: The support frame 31 includes two support columns 311, a bottom plate 312 is set at the bottom of the support column 311, an oblique support rod 313 is connected between the support plate 53 and the support column 311, and a transverse reinforcement rod 314 is set between the two columns 222 to connect the two support columns 311 as one. The two sides of the fixed frame 32 are respectively connected to the two support columns 311, and a reinforcing rib plate 315 is connected between the fixed frame 32 and the support column 311.

[0038] The fixing frame 32 is arranged in a rectangular shape. A plurality of main cylinders 34 are arranged around the fixing frame 32 . The telescopic ends of the main cylinders 34 are connected to the lifting frame 33 . The lifting frame 33 is driven to move up and down by the main cylinders 34 .

[0039] The 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 the 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 the first guide hole is equipped with a first guide rod 3513.

The control unit is used to control the lifting assembly 41 to rise or fall according to the photoelectric sensor signal.

The photoelectric sensor transmits a signal to the control unit. The control unit controls the lifting assembly 41 to descend, thereby lowering the height of the top surface of the plate 7 on the support platform 42, so that the height of the top surface of the plate 7 on the support platform 42 is always maintained within a certain height range with the loading plate 221. On the one hand, it ensures that the loading plate 221 can smoothly reach the top of the stacking mechanism 4, and on the other hand, it avoids the plate 7 from being scattered during the process of falling from the loading plate 221 to the support platform 42.

[0042] Example 2 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 adapt to 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, and the cylinder stroke control mechanism 6 includes a mounting plate 61, a magnet sheet 62 and a plurality of Hall elements 63.

[0043] Specifically, a mounting plate 61 is arranged on the right side of the lifting frame 33. The mounting plate 61 is arranged above the second guide rod 3523 along the length direction of the second guide rod 3523. The Hall element 63 is arranged on the mounting plate 61 along the length direction of the mounting plate 61. The magnet sheet 62 is arranged 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 run along the axial direction of the second guide hole. When the magnet sheet 62 of the second guide rod 3523 passes through the Hall element 63 on the mounting plate 61 in sequence, the corresponding Hall element 63 sends a signal to the control center when sensing the magnet sheet 62, so as to control the stroke of the second push rod 3522, thereby adapting to the limit of plates 7 of different widths.

[0044] Example 3 like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Fig. 9As shown, in this embodiment, the difference from Embodiment 1 is that there is a cross bar 223 between the two uprights 222, and a hanging mechanism 5 is provided on the cross bar 223, and the hanging mechanism 5 includes a vertical cylinder 51 connected to the cross bar 223, and the telescopic end of the vertical cylinder 51 is connected to a slide cylinder 52, and the vertical cylinder 51 is used to drive the slide cylinder 52 to move up and down, and the telescopic end of the slide cylinder 52 is connected to a support plate 53, and the slide cylinder 52 is used to drive the support plate 53 to move laterally in or out of the bottom of the loading plate 221.

[0045] The specifications of the plates 7 to be cut are different, and the corresponding loading plates 221 for loading the plates 7 will also be designed with different specifications. When the width of the loading plates 221 is too large (i.e., horizontal cutting), and for weight and cost considerations, the thickness of the loading plates 221 cannot be set too thick, so the middle of the loading plates 221 between the two columns 222 will sink. The sinking of the middle of the loading plates 221 will easily cause the plates 7 on the loading plates 221 to become scattered. In this embodiment, a cross bar 223 is added between the two columns 222. The hanging mechanism 5 is installed through the cross bar 223. In the hanging mechanism 5, the sliding cylinder 52 and the support plate 53 connected to the sliding cylinder 52 are extended to the height of the loading plate 221 through the vertical cylinder 51, and then the support plate 53 is driven by the sliding cylinder 52 to extend under the loading plate 221, and then the support plate 53 is driven by the vertical cylinder 51 to abut against the bottom surface of the loading plate 221, thereby forming support for the middle part of the loading plate 221 to reduce the sinking phenomenon in the middle part of the loading plate 221, thereby avoiding the scattering of the cut plates on the loading plate 221.

[0046] Furthermore, a first avoidance gap is provided on the side of the fixed frame 32 close to the feeder 1 and on the side away from the feeder 1, a second avoidance gap is provided on the side of the lifting frame 33 close to the feeder 1, and an opening is provided on the side of the lifting frame 33 away from the feeder 1, so that during the operation of the mobile mechanism 2, the hanging mechanism 5 will not interfere with the fixed frame 32 and the lifting frame 33.

[0047] Furthermore, the limiting component 35 also includes a third push rod assembly 353, the third push rod assembly 353 includes two third push rods 3531, which are respectively located on both sides of the first avoidance gap, the third push rod 3531 is connected to a third cylinder 3532, the third cylinder 3532 is used to drive the third push rod 3531 to move horizontally, the third cylinder 3532 is connected to the lifting frame 33, and the lifting frame 33 is provided with a third guide hole on one side close to the material rack 22, and the third guide hole is equipped with a third guide rod 3533, and the third guide rod 3533 passes through the third guide hole and is connected to the third push rod 3531. When the loading plate 221 runs above the stacking mechanism 4, the lifting frame 33 in the material blocking mechanism 3 descends to the position of the loading 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 close to the unloader 1, thereby preventing the plate 7 from being carried out by the friction force of the loading plate 221 during the extraction process of the loading plate 221, which can further reduce the possibility of the plate 7 being scattered.

[0048] Furthermore, the limiting component 35 also includes a shift rod assembly 354, which includes two shift rods 3541, which are respectively located on both sides of the first avoidance gap. The shift rod 3541 is connected to the fourth cylinder 3542, and the fourth cylinder 3542 is used to drive the shift rod 3541 to move vertically. The fourth cylinder 3542 is connected to the fixed frame 32, and a fourth guide hole is set on the side of the fixed frame 32 away from the third push rod assembly 353. The fourth guide hole is equipped with a fourth guide rod, and the fourth guide rod passes through the fourth guide hole and is connected to the shift rod 3541.
