[0057] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0058] In embodiments of the present invention, the sheet material is a face mask, or it can be other sheet materials such as cotton pads.

[0059] like Figure 1 and Figure 2 As shown, the flat packaging inspection, boxing, and palletizing system of the present invention includes a conveyor line, a flat packaging inspection device 105, a packing device 106, a neat compression device, a packing reversing device 107, a pushing device 23, a material handling conveyor line 108, a first robot 109, a boxing gripper 113, a second robot 118, an empty box conveyor line 111, a box body conveyor line 110, a truss 112, a box support assembly 114, a boxing platform 115, a box sealing machine 116, a non-powered roller conveyor 117, a carton rack 120, and a box opening and folding machine 121.

[0060] like Figure 1 As shown, the conveyor line includes a receiving conveyor 102, a flying sheet conveyor 103, and an adsorption conveyor 104. The receiving conveyor 102 is used to receive the sheet material produced in the previous process, the flying sheet conveyor 103 is used to accelerate the conveying of sheet material, and the adsorption conveyor 104 uses a vacuum adsorption method for conveying.

[0061] The flat packaging inspection device 105 is installed on the conveyor line and can perform flat packaging inspection on the masks. The flat packaging inspection includes: appearance inspection, size inspection, air permeability test and other contents.

[0062] like Figure 12 As shown, the sheet material collecting device 106 in this embodiment includes two sets of rollers 51 arranged vertically, a sheet material collecting belt 52 passing over the rollers, and a collecting plate 53 disposed on the sheet material collecting belt 52. When the motor drives the rollers to rotate, the collecting plate 53 can move up and down in the vertical part of the sheet material collecting belt 52, and the pair of collecting plates 53 can remain relatively stationary. As more and more sheet material 1 falls onto the collecting plate 53 on the conveyor line, the pair of collecting plates 53 will also slowly descend to bear more sheet material. When enough sheet material is collected, the pair of collecting plates 53 will also move away from each other under the action of the sheet material collecting belt 52, and the sheet material on the collecting plate 53 will fall into the neat compression device.

[0063] like Figure 3 and Figure 4As shown, the neat compression device in this embodiment is located below the sheet collection device 106 and includes a first hopper baffle 31, a second hopper baffle 321, a receiving base 331, a cover plate 341, a push plate 351, a second hopper cylinder 322, an upper roller 334, a lower roller 333, a receiving belt, a receiving motor 332, a receiving guide rail, a cover plate cylinder 342, and a push plate cylinder 352.

[0064] like Figure 3 As shown, the first hopper baffle 31 is fixedly installed.

[0065] like Figure 3 As shown, the second hopper baffle 321 is arranged parallel to the first hopper baffle 31; the second hopper cylinder 322 is arranged laterally, and the moving end of the second hopper cylinder 322 is fixedly connected to the second hopper baffle 321; under the drive of the second hopper cylinder 322, the second hopper baffle 321 can be moved laterally.

[0066] like Figure 3 As shown, the receiving base 331 is located between the first hopper baffle 31 and the second hopper baffle 321. The lower roller 333 is located below the upper roller 334. The receiving belt passes over the upper roller 334 and the lower roller 333. The receiving motor 332 drives either the upper roller 334 or the lower roller 333 to rotate. The receiving guide rail is vertically arranged. The receiving base 331 is fixedly connected to the sliding pair of the receiving guide rail and to the receiving belt. When the receiving motor 332 rotates, it drives either the upper roller 334 or the lower roller 333 to rotate, thereby driving the receiving belt and the receiving base 331 to move up and down. The receiving base 331 can move up and down between the first hopper baffle 31 and the second hopper baffle 321 to receive sheet materials.

[0067] like Figure 3 As shown, a cover plate 341 is located above the receiving base 331, and a cover plate cylinder 342 is arranged longitudinally. The cover plate 341 is fixedly connected to the moving end of the cover plate cylinder 342. Under the drive of the cover plate cylinder 342, the cover plate 341 can move longitudinally between the first hopper baffle 31 and the second hopper baffle 321. The first hopper baffle 31, the second hopper baffle 321, the receiving base 331, and the cover plate 341 surround to form a hopper. The cover plate 341 is provided with an opening 343, which extends from the edge of the cover plate 341 near the hopper end into the interior. The width of the opening 343 in the transverse direction is greater than the width of the push plate 351 in the transverse direction.

[0068] like Figure 3 and Figure 4As shown, the push plate 351 is located below the cover plate 341 and above the receiving base 331; the push plate cylinder 352 is arranged longitudinally, and the push plate 351 is fixedly connected to the moving end of the push plate cylinder 352. Under the drive of the push plate cylinder 352, the push plate 351 can push the sheet material in the hopper longitudinally.

[0069] like Figure 3 As shown, when there is no sheet material on the receiving base 331, the receiving base 331 is located in the middle position of the first hopper baffle 31 in the vertical direction. When the first batch of sheet material falls onto the receiving base 331, the receiving base 331 moves downward to the lowest position to wait for the second batch of material to fall. After the second batch of material falls, the second hopper baffle 321 moves laterally towards the first hopper baffle 31. At this time, the hopper space becomes smaller, which straightens the sheet material in the hopper laterally. At the same time, the vibration generated by the cylinder during operation also straightens the sheet material. Then the cover plate 341 moves longitudinally to the top of the hopper. At this time, the sheet material is located between the cover plate 341 and the receiving base 331. Then the receiving base 331 moves upward to compress the sheet material in the vertical direction. At this time, the sheet material is in a neat compressed state. Then, the push plate 351, under the action of the push plate cylinder 352, pushes the compressed sheet material out of the hopper. The receiving base 331 consists of two separate receiving plates, the distance between which is greater than the width of the push plate 351. This allows the push plate 351 to extend between the two receiving plates and vertically downwards below them, ensuring that material on the receiving base 331 is not left behind due to insufficient length of the push plate 351. Similarly, since the width of the opening 343 on the cover plate 341 is greater than the width of the push plate 351, the push plate 351 can extend upwards into the opening 343 of the cover plate 341. By extending upwards into the opening 343 and downwards between the two receiving plates, the push plate 351 ensures that all compressed sheet material is pushed out of the hopper and to the sheet collection and reversing device.

[0070] like Figure 5 and Figure 6 As shown, the commutation device 107 in this embodiment includes a rotating mechanism 21.

[0071] like Figure 5As shown, the rotating mechanism 21 includes a rotating module and a storage module. The storage module includes four plates: two parallel first plates 211 and two parallel second plates 212. The first plates 211 and the second plates 212 are perpendicular to each other and are fixedly connected in pairs. The inner sides of any two parallel plates A and the outer side of a plate B perpendicular to plate A form a storage space. The storage space formed by the inner sides of two horizontal plates and the outer side of a vertical plate is the first storage space 213, and the storage space formed by the inner sides of two vertical plates and the outer side of a horizontal plate is the second storage space 214. The storage module has a total of eight storage spaces. After the rotating module drives the storage module to rotate 90° along the longitudinal axis, the first storage space 213 becomes the second storage space 214, and the second storage space 214 becomes the first storage space 213.

[0072] The rotation module enables the storage module to rotate along the longitudinal axis. The rotation module is a rotary motor 215 arranged longitudinally; the rotating end of the rotary motor 215 is fixedly connected to the storage module.

[0073] like Figure 5 As shown, the pushing device 23 includes a pushing cylinder 231 and a pushing plate 232 arranged longitudinally; the pushing plate 232 is fixedly connected to the moving end of the pushing cylinder 231. The pushing cylinder 231 can drive the pushing plate 232 to move longitudinally, and the pushing plate 232 pushes the vertically stacked sheet materials in the second storage space 214 to the conveying station on the material handling conveyor line.

[0074] like Figure 5 and Figure 6 As shown, when the second storage space 214 cannot be aligned with the conveying station on the material handling conveyor line, the lateral position of the storage module can be adjusted using the lateral adjustment device 22. The lateral adjustment device 22 includes a lead screw 222 arranged laterally, a handwheel 221 that drives the lead screw 222 to rotate, a bushing that cooperates with the lead screw 222, and a lateral adjustment guide rail 223 arranged laterally; the rotating mechanism 21 is fixedly connected to the bushing and the lateral adjustment guide rail 223. When the handwheel 221 is rotated, the lead screw 222 can be rotated, thereby driving the bushing and the rotating mechanism 21 to perform lateral displacement, realizing the lateral movement of the storage module.

[0075] like Figure 7 As shown, the material handling conveyor line 108 in this embodiment includes a pair of sprocket assemblies 42, a motor 433, a first chain 431, a second chain 432, a blocking block 41, a drive sprocket 421, and a drive chain.

[0076] like Figure 8 and Figure 9As shown, each sprocket assembly 42 includes a shaft 422, a first sprocket 423 coaxial with and fixedly connected to the shaft 422, a second sprocket 424 coaxial with and rotatably connected to the shaft 422, and an electromagnetic clutch 425 for synchronizing the second sprocket 424 with the shaft 422.

[0077] like Figure 8 and Figure 9 As shown, the drive sprocket 421 is coaxially and fixedly connected to the shaft 422 of any sprocket assembly 42; the drive chain passes around the rotating end of the motor 433 and the drive sprocket 421. When the motor 433 rotates, it drives the drive sprocket 421 to rotate via the drive chain, which in turn drives the shaft 422 and the first sprocket 423 to rotate.

[0078] The electromagnetic clutch 425 refers to a friction clutch that generates clamping force using electromagnetic force. In this embodiment, the electromagnetic clutch 425 includes an outer sleeve, an inner sleeve, and a friction plate for transmitting torque between the outer and inner sleeves. The outer sleeve is fixedly connected to the second sprocket 424, the inner sleeve is fixedly connected to the rotating shaft 422, and the friction plate is fixedly connected to the outer sleeve. When the electromagnetic clutch 425 is not energized, the friction plate does not rub against the inner sleeve; at this time, the rotating shaft 422 rotates, but the second sprocket 424 does not rotate. When the electromagnetic clutch 425 is energized, the friction plate rubs against the inner sleeve; at this time, the rotation of the rotating shaft 422 drives the second sprocket 424 to rotate.

[0079] When it is necessary to adjust the distance between the blocking blocks 41, the electromagnetic clutch 425 is closed. The power sprocket 421 drives the rotating shaft 422 to rotate, and the rotating shaft 422 drives the first sprocket 423 to rotate. The second sprocket 424 does not rotate with the rotating shaft 422. At this time, the distance between the blocking blocks 41 can be adjusted to accommodate the conveying of materials 1 of different widths. After the distance adjustment is completed, the electromagnetic clutch 425 is opened. At this time, the first sprocket 423 and the second sprocket 424 rotate synchronously with the rotating shaft 422, and the distance between the blocking blocks 41 remains unchanged.

[0080] like Figure 10 and Figure 11 As shown, the present invention also includes a rotary gripper, comprising a mounting plate, a gripper cylinder 63, a sliding plate 611, a rocker arm 621, a multi-link gripper 64, and a push plate cylinder 612.

[0081] The mounting plate is the support platform for the entire rotating gripper, and it is fixedly connected to the end effector of the first robot.

[0082] The gripper cylinder 63 is a linear cylinder, vertically positioned below the mounting plate, and rotatably connected to the mounting plate.

[0083] The rocker arm 621 is fixedly connected to the gripper cylinder 63 at one end and a pulley 622 is installed at the other end; the pulley 622 is set in an arc-shaped opening.

[0084] A sliding plate 611, horizontally positioned, is capable of lateral movement. An arc-shaped opening is provided on the sliding plate 611. A push-plate cylinder 612 is positioned laterally, and its piston rod is fixedly connected to the sliding plate 611. When the piston rod of the push-plate cylinder 612 moves laterally, it drives the sliding plate 611 to move laterally as well. A pulley 622 on the rocker arm 621 is positioned within the arc-shaped opening. When the sliding plate 611 moves laterally, the pulley 622 slides and moves along the arc-shaped opening, causing the rocker arm to rotate. The rotation of the rocker arm drives the gripper cylinder 63 to rotate relative to the mounting plate, thereby causing the multi-link gripper 64 to rotate.

[0085] The multi-link gripper 64 includes a first link 642, a second link 643, a third link 644, and gripping teeth 645. One end of the first link 642 is hinged to the fixed end 641 of the gripper cylinder 63, and the other end is hinged to the gripping teeth 645. One end of the second link 643 is hinged to the fixed end 641 of the gripper cylinder 63, and the other end is hinged to the gripping teeth 645. One end of the third link 644 is hinged to the middle of the second link 643, and the other end is hinged to the moving end of the gripper cylinder 63. The first link 642 and the second link 643 are arranged in parallel, and the hinge means a rotatable connection. When the piston rod of the gripper cylinder 63 extends, the two gripping teeth 645 move away from each other, allowing material to be placed down; when the gripper cylinder 63 retracts, the two gripping teeth 645 move closer together, allowing material to be gripped.

[0086] In addition, multiple rotating grippers can be installed at the end of the robotic arm as needed to simultaneously pack multiple batches of materials.

[0087] The first robot 109 is used to pick up sheet materials from the conveying station of the material handling conveyor line 108 and place them into the box; the second robot 118 is used to stack the boxes. Both the first robot 109 and the second robot 118 are six-axis robots, and actuators are installed at the end of their robot arms. The box-packing gripper 113 is fixedly connected to the moving end of the truss 112, and the truss 112 can drive the box-packing gripper 113 to move laterally, longitudinally, and vertically.

[0088] The first robot 109, the box-packing gripper 113, and the second robot 118 are respectively used to put stacked sheet materials into boxes, put boxes containing sheet materials into containers, and stack containers containing boxes.

[0089] Empty box conveyor line 111 is used to convey empty boxes, and box conveyor line 110 is used to convey boxes into which sheet materials are placed.

[0090] The packing platform 115 and the box support assembly 114 are mechanisms used to place the box into the box. The packing platform 115 is a support platform for the box, and the box support assembly 114 is used to support the ears and cover of the box when it is placed into the box, so as to facilitate smooth packing.

[0091] The carton sealing machine 116 is used to seal the carton after a box is placed inside it.

[0092] Cardboard box rack 120 is used to store folded cardboard boxes.

[0093] Carton opening and folding machine 121 is used to open folded cartons.

[0094] Flat stacking of sheet materials refers to each sheet material being located on a horizontal plane and stacked from low to high; vertical stacking of sheet materials refers to each sheet material being located on a vertical plane.
