[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Reference Figure 1-8 A corrugated and slitting cutting unit that simultaneously performs corrugated shearing and slitting includes an automatic feeder 1, a chain conveyor 2, a corrugated shearing chamber 3, a positioning conveyor 4, a slitting machine 5, and a receiving table 6. The corrugated shearing chamber 3 is connected to the automatic feeder 1 via the chain conveyor 2. After the sheet metal is corrugated in the corrugated shearing chamber 3, it is adjusted to the slitting position by the positioning conveyor 4, then conveyed by the chain conveyor 2 to the slitting machine 5 for slitting, and finally collected and discharged by the receiving table 6, completing the processing.

[0040] The automatic feeder 1 can be implemented as a palletizing feeder or a leveling conveyor. When the automatic feeder 1 is implemented as a palletizing feeder, the technicians stack multiple boards to be processed in the frame of the automatic feeder 1. The automatic feeder 1 uses a vacuum suction cup that can move vertically to pick up the boards and then conveys them to the chain conveyor 2. Preferably, the automatic feeder 1 is equipped with a slitting device. The slitting device can cooperate with the vacuum suction cup to slit the boards when the vacuum suction cup picks them up, preventing double-stretching during the wave shearing process and damaging the cutter.

[0041] When the automatic feeder 1 is implemented as a leveling conveyor, the rolled sheet will be fed to the automatic feeder 1 at a predetermined speed. The automatic feeder 1 will level the bent sheet and then convey it to the chain conveyor 2.

[0042] The chain conveyor 2 has guide mechanisms on its left and right sides to adjust the plates conveyed by the automatic feeder 1 to a suitable position and convey them to the shear chamber 3.

[0043] The shearing chamber 3 is equipped with a shearing unit 7 and a discharge unit 8. The shearing chamber 3 encloses and protects the shearing unit 7 and the discharge unit 8 to protect their related structures and prevent sheet metal debris from flying out and causing danger during shearing. A CNC console is installed outside the shearing chamber 3, and technicians use the CNC console to control the operation of the shearing unit 7 and the discharge unit 8.

[0044] The corrugated shear unit 7 includes a corrugated shear table 71, a transverse corrugated shear seat 72, a longitudinal corrugated shear seat 73, and a receiving tray 74. The corrugated shear table 71 is installed above the receiving tray 74. The corrugated shear table 71 has a drop plate cavity 701. The drop plate cavity 701 has a cross-cutting table 75 on the side near the chain conveyor 2. The transverse corrugated shear seat 72 is located above the cross-cutting table 75, and the longitudinal corrugated shear seat 73 is located above the drop plate cavity 701.

[0045] The wave shearing unit 7 also includes two support plate devices 76. Each support plate device 76 includes a support plate column 761 installed inside the drop plate cavity 701. The support plate column 761 extends from the chain conveyor 2 to the positioning conveyor 4. The support plate column 761 is axially rotatable within the drop plate cavity 701. The side wall of the drop plate cavity 701 has a horizontal groove. The rotation shaft 762 of the support plate column 761 is inserted into the horizontal groove, thereby enabling horizontal movement to adjust the distance between the two support plate columns 761.

[0046] The transverse corrugated shear seat 72 includes a lower pressure beam 721, transverse corrugated shears 722, and a lower insert 723. The transverse corrugated shears 722 are horizontally mounted on the lower surface of the lower pressure beam 721, and the lower pressure beam 721 can be driven to move vertically. After being leveled by the automatic feeder 1, the rolled sheet is conveyed to the corrugated shear table 71 by the chain conveyor 2. The lower pressure beam 721 moves downward periodically according to the shearing requirements and the traveling speed of the sheet, so as to transversely corrugate the sheet into smaller segments with the help of the transverse corrugated shears 722.

[0047] The lower insert 723 is installed on the lower surfaces of both ends of the lower pressure beam 721. The cross-cutting table 75 is provided with insert grooves 702 and insert channels 703 at positions corresponding to the transverse wave shears 722 and the lower insert 723. After the transverse wave shears 722 moves down and cuts the plate, it will continue to move down into the insert groove 702. At the same time, the lower insert 723 will also move down a certain distance in the insert channel 703.

[0048] The lower insertion post 723 has a toothed vertical groove 7201 on its side. The cross-cutting table 75 has a first linkage member 77 installed inside. The first linkage member 77 includes two coaxially connected linkage gears, one of which meshes with the toothed vertical groove 7201 so that the lower insertion post 723 can drive the first linkage member 77 to rotate axially when it moves vertically.

[0049] The transverse cutting table 75 has an adjustment cavity 704 that connects to the horizontal groove of the drop plate cavity 701. An adjustment component 78 capable of horizontal movement is installed in the adjustment cavity 704. The adjustment component 78 is electrically connected to the CNC table, and the operation of the adjustment component 78 is controlled by the CNC table.

[0050] The rotating shaft 762 is inserted into the adjusting cavity 704 and passes through the adjusting member 78. A second linkage member 763 is installed at the end of the rotating shaft 762 inserted into the adjusting cavity 704. The second linkage member 763 and the first linkage member 77 are connected by a linkage rack 764. The linkage rack 764 is horizontally movable in the adjusting cavity 704. The second linkage member 763 and the first linkage member 77 respectively mesh with the linkage rack 764 so that the rotating shaft 762 can rotate axially together with the first linkage member 77.

[0051] The adjusting member 78 can drive the rotating shaft 762 to move vertically and maintain it in a fixed vertical position, so that the second linkage member 763 can engage or disengage with the linkage rack 764. When it is necessary to drive the frame device 76 to adjust its horizontal position, the adjusting member 78 first controls the second linkage member 763 to disengage from the linkage rack 764, so that the second linkage member 763 can move horizontally freely without being affected by the linkage rack 764. After the frame device 76 has moved horizontally, the adjusting member 78 controls the second linkage member 763 to re-engage with the linkage rack 764 to restore the linkage relationship between the frame device 76 and the lower insertion post 723.

[0052] It is worth mentioning that the vertical movement stroke of the lower insertion post 723 can drive the second linkage member 763 to rotate at least 60 degrees, and the linkage rack 764 covers the horizontal movement range of the adjustment member 78, so that after the second linkage member 763 moves within the adjustment range, it can be controlled by the adjustment member 78 to restore the meshing relationship with the linkage rack 764.

[0053] The lower end of the lower insertion post 723 is fitted with a rotating sleeve 79, which is capable of axial rotation. The lower end of the rotating sleeve 79 extends out of the wave shear table 71 and is coaxially mounted with a drive gear. The outer side of the rotating sleeve 79 has a spiral groove 7901. The lower insertion post 723 has a drive block 724 disposed in the spiral groove 7901. The drive block 724 can slide in the spiral groove 7901. The vertical position of the rotating sleeve 79 is fixed. When the drive block 724 moves vertically with the lower insertion post 723, it can drive the rotating sleeve 79 to rotate axially.

[0054] When the corrugated shear unit 7 corrugates the leveled sheet metal, it first adjusts the spacing between the support columns 761 according to the width of the sheet metal so that the sheet metal can be just lifted by the support columns 761, and the side of the sheet metal is inside the rotating shaft 762. After the sheet metal has traveled a predetermined distance above the drop chamber 701, the transverse corrugated shear seat 72 presses down to cut the sheet metal. At the same time, the lower insertion column 723 moves down and rotates the support columns 761 and the rotating sleeve 79. The support columns 761 are triangular prisms. When lifting the sheet metal, the side of the support column 761 is in contact with the sheet metal. After the support column 761 rotates, the side that was originally in contact with the sheet metal rotates and stands upright. The support column 761 can no longer lift the sheet metal. The cut sheet metal will slide down into the drop chamber 701 and be received by the receiving tray 74. Then the transverse corrugated shear seat 72 is raised back to the initial position, and the support columns 761 and the rotating sleeve 79 also rotate back to the initial position.

[0055] The receiving tray 74 includes a fixed base 741, a rotating disk 742, and a limiting component 743. The fixed base 741 is fixedly installed below the wave shear table 71. The rotating disk 742 is axially rotatable and installed in the fixed base 741. An annular groove is formed between the outer wall of the rotating disk 742 and the inner wall of the fixed base 741. The outer wall of the rotating disk 742 also has teeth. The drive gear at the lower end of the rotating sleeve 79 is fitted into the annular groove and meshes with the teeth on the outer wall of the rotating disk 742, so that the rotating sleeve 79 can drive the rotating disk 742 to rotate when it rotates.

[0056] The upper surface of the rotating disk 742 covers the entire drop chamber 701, so that various shapes of plates falling into the drop chamber 701 can be received by the rotating disk 742. The rotating disk 742 has a cross-shaped groove 7401 inside. Each of the four branches of the cross-shaped groove 7401 is equipped with a limiting plate 7431. The rotating disk 742 is also equipped with a controller 7432 in the four areas divided by the cross-shaped groove 7401. The side walls of the four branches of the cross-shaped groove 7401 are provided with displacement grooves 7402. The limiting plate 7431 passes through the displacement groove 7402 and is connected to the rotating shaft of the controller 7432, so that the controller 7432 can control the limiting plate 7431 to rotate axially and move horizontally. When the limiting plate 7431 is rotated to a vertical position, it can extend upward out of the cross-shaped groove 7401.

[0057] The controller 7432 is electrically connected to the CNC table. Before the wave shearing, the controller 7432 will adjust the limit plate 7431 to the designated position according to the shearing needs. After the plate is wave sheared, it will fall onto the upper surface of the rotary table 742 and be limited. During the time when the transverse wave shear seat 72 is raised and the next section of plate is transported, the controller 7432 can control the limit plate 7431 to push the plate to the discharge unit 8, and finally send the plate out of the wave shear chamber 3 and to the positioning conveyor 4.

[0058] It is worth mentioning that when the transverse wave shear seat 72 moves downward for cutting, the rotating sleeve 79 will drive the rotating disk 742 to rotate. The rotating disk 742 is rotated 90 degrees by the rotating sleeve 79 during the entire process of the lower insertion post 723 moving downward. At this time, the plate is received and limited by the rotating disk 742. When the transverse wave shear seat 72 is raised, the rotating disk 742 is rotated 90 degrees again by the rotating sleeve 79 to reach the initial position. At this time, the orientation of the bent edge of the plate after wave shearing will also rotate 90 degrees.

[0059] The longitudinal wave shear seat 73 includes a cover plate 731, a longitudinal wave shear 732, a guide plate 733, and a conveyor seat 734. When the transverse wave shear seat 72 is working, the longitudinal wave shear seat 73 is held above the drop plate cavity 701; when wave shearing a single piece of plate, the transverse wave shear seat 72 stops working, the support columns 761 are separated to the maximum distance, and the conveyor seat 734 moves down between the two support columns 761 to fill the opening at the top of the drop plate cavity 701.

[0060] Multiple conveying rollers 735 are installed inside the conveying seat 734. These rollers 735 are capable of axial rotation and vertical movement within the conveying seat 734. When the conveying rollers 735 move upwards, they partially protrude from the upper surface of the conveying seat 734; when they move downwards, they submerge into the upper surface of the conveying seat 734. After a single sheet of material is conveyed into the corrugated shear chamber 3, it is received by the conveying seat 734. The conveying rollers 735 partially protrude from the upper surface of the conveying seat 734 and rotate to move the entire sheet of material to the upper surface of the conveying seat 734.

[0061] The cover plate 731 is installed above the conveyor seat 734, and there is a certain distance between the cover plate 731 and the conveyor seat 734. The longitudinal wave shears 732 and the guide plate 733 are installed on the lower surface of the cover plate 731. The longitudinal wave shears 732 and the guide plate 733 extend from the chain conveyor 2 to the positioning conveyor 4. The longitudinal wave shears 732 and the guide plate 733 can move horizontally in a direction perpendicular to the extension direction.

[0062] The longitudinal wave shears 732 and guide plate 733 are also capable of vertical movement. The horizontal and vertical movement of the longitudinal wave shears 732 and guide plate 733 is controlled by a CNC table. Before receiving the sheet material, the guide plate 733 moves to a designated position according to the size of the sheet material. After the sheet material is conveyed to the upper surface of the conveyor seat 734, it will be limited and guided by the guide plate 733. After the sheet material stops, the longitudinal wave shears 732 presses down on the sheet material to cut it. The cut sheet material will be conveyed out of the wave shear chamber 3 by the conveyor roller 735 and sent to the positioning conveyor 4.

[0063] Preferably, waste bins 705 are provided on both sides of the wave shear table 71. After a single piece of board is longitudinally cut, the remaining material can be pushed into the waste bin 705 by the horizontal movement of the longitudinal wave shear 732 or the guide plate 733, so as not to affect the cutting of the next piece of board.

[0064] The sheet material conveyed to the shearing bin 3 in a single piece is conveyed to the positioning conveyor 4 in a longitudinally extended state with folded edges after being cut. The sheet material continuously conveyed to the shearing bin 3 in a roll is cut and adjusted for rotation by the rotary table 742. Then, it is sent out of the shearing bin 3 by the discharge unit 8 and sent to the positioning conveyor 4 in a longitudinally extended state with folded edges.

[0065] After receiving the sheet material after the wave shearing, the positioning conveyor 4 conveys the sheet material to the chain conveyor 2 with the curved edge perpendicular to the circular blade of the slitting machine 5. The chain conveyor 2 conveys the sheet material to the slitting machine 5, where it will be slitted. Finally, the receiving table 6 collects the material and discharges it, completing the processing.

[0066] The discharge unit 8 includes a lifting slope 81, a telescopic device 82, and a locking assembly 83. The bottom of the lifting slope 81 is transitionally connected to the receiving tray 74 so that the sheet material can be smoothly moved from the receiving tray 74 to the slope surface of the lifting slope 81. The telescopic device 82 includes a fixing control component 821, a telescopic arm 822, and a connecting rod 823. The lifting slope 81 is concave inward, and multiple fixing control components 821 are arranged on both sides of the concave groove. A pair of telescopic arms 822 are installed on the fixing control component 821 in the inclined direction of the lifting slope 81. The fixing control component 821 can control the two telescopic arms 822 to extend and shorten in a regular manner. The two ends of the connecting rod 823 are connected to the ends of the two telescopic arms 822 at the same height.

[0067] The locking assembly 83 is arranged and installed on the connecting rod 823. The locking assembly 83 includes an air extractor 831 and a docking plug 832. The air extractor 831 is installed inside the telescopic arm 822, and the docking plug 832 is installed outside the telescopic arm 822. The docking plug 832 is preferably a horn-shaped hollow soft plug. The internal space of the docking plug 832 is connected to the air extractor 831. After the plate covers the upper opening of the docking plug 832, the air extractor 831 will draw away the air in the docking plug 832, thereby locking the docking plug 832 to the surface of the plate. At this time, the plate can move together with the telescopic arm 822 on which the locking assembly 83 is installed.

[0068] The telescopic arm 822, which is installed on the same fixed control component 821, extends and retracts synchronously, while the vacuum pump 831 is only turned on when the connecting rod 823 moves upward. The plate will gradually move upward as the connecting rod 823 moves up and down. The plate that originally fell on the rotary table 742 will be lifted upward by the discharge unit 8 and sent to the positioning conveyor 4.

[0069] Each of the docking plugs 832 is provided with a detection device 84. The detection device 84 includes a sleeve 841, a moving post 842, and a return spring 843. The sleeve 841 is fixedly installed inside the docking plug 832. The sleeve 841 has an open cavity 8401 that opens upward. The moving post 842 and the return spring 843 are disposed inside the open cavity 8401.

[0070] A compression sensor 844 is installed at the upper end of the movable column 842, and a permanent magnet block 845 is provided at the lower end of the movable column 842. The upper end of the return spring 843 is connected to the movable column 842, and the lower end is connected to the inner wall of the open cavity 8401. When the return spring 843 is at its normal length, it keeps the movable column 842 inside the docking plug 832.

[0071] An electromagnet 846 is provided inside the sleeve 841. When the electromagnet 846 is energized, its upper end can generate the same magnetic pole as the lower end of the permanent magnet block 845, so as to push the moving column 842 upward and tend to protrude out of the docking plug 832. After the electromagnet 846 is de-energized, the return spring 843 can pull the moving column 842 back into the docking plug 832.

[0072] Before each start-up, the vacuum pump 831 first powers the electromagnet 846 to move the movable column 842, on which the compression sensor 844 is mounted, upward. If the connecting plug 832 is covered with a plate, the compression sensor 844 will be squeezed by the plate when the movable column 842 moves upward. The vacuum pump 831 can only start when it receives information that the connecting rod 823 is moving upward and the compression sensor 844 is being squeezed. The vacuum pump 831 that is not covered by the plate will not start and will run idle to reduce energy consumption.
