[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] In order to better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0039] The following will be combined with the attached Figures 1-7 A detailed description of the implementation of a sheet handling device provided by the present invention will be given.

[0040] A sheet handling device 1 according to an embodiment of the first aspect of the present invention includes a conveying part, a stacking part, a transition part and a turntable mechanism.

[0041] The conveying unit is used to displace a single sheet. The stacking unit includes a windmill 201 and a stacking platform 202. One side of the windmill 201 is connected to the conveying unit, and the other side is connected to the stacking platform 202 to rotate and stack the sheets conveyed by the conveying unit in a set quantity on the stacking platform 202 to form a stack. The transition unit includes a transition platform 301, a stacking hook mechanism 302 and a stacking pushing mechanism 303. The transition platform 301 is connected to the stacking platform 202. The stacking hook mechanism 302 is movable between the stacking platform 202 and the transition platform 301 to drive the stack on the stacking platform 202 to be transferred to the transition platform 301. The stacking pushing mechanism 303 is adapted to push the stack on the transition platform 301 into the turntable mechanism. A plurality of conveying channels 401 are defined on the turntable mechanism, and each conveying channel 401 is adapted to be selectively connected to the transition platform 301 and the medium packaging machine according to the required packaging form of the product.

[0042] Among them, the sheet can be a small sanitary napkin. The sheet sorting device 1 is arranged between the main machine of the production line of small sanitary napkins and the medium packaging machine. After the small sanitary napkins are stacked into a stack by the sheet sorting device 1, they are sent to the packaging machine for packaging. The stack stacked according to the sheet sorting device 1 is a vertical sheet stack. The vertical sheet stack can be in a horizontal or vertical sheet packaging form through the turntable mechanism and is sent into the medium packaging machine for packaging.

[0043] Therefore, according to the sheet sorting device 1 of the present invention, through the setting of the transition unit, the stack completed on the stacking platform 202 can be timely transferred to the transition platform 301. At this time, the windmill 201 and the stacking platform 202 cooperate to continue stacking the sheets, ensuring that the windmill 201 can continuously stack, realizing the full automation of the packaging equipment, and improving the packaging efficiency. In addition, through the plurality of conveying channels 401 arranged on the turntable mechanism, the medium packaging machine can be reasonably arranged, and different packaging requirements of users can be met, improving the versatility of the packaging equipment.

[0044] Combined with Figure 2 and Figure 4 , in some examples, the conveying unit includes a first negative pressure conveyor 101 arranged obliquely. The outlet end of the first negative pressure conveyor 101 is connected to the windmill 201. Among them, the higher end of the obliquely arranged first negative pressure conveyor 101 is the inlet end, and the lower end is the outlet end. With such a setting, the first negative pressure conveyor 101 and the windmill 201 can cooperate to stack the small sanitary napkins into a stack in an upright state. In addition, the first negative pressure conveyor 101 is a product transfer mechanism using vacuum adsorption. That is to say, the first negative pressure conveyor 101 can include an air suction box and an adsorption conveyor belt. A plurality of through holes are distributed on the adsorption conveyor belt, and the adsorption conveyor belt is attached to the air suction box. The small sanitary napkins are conveyed by the vacuum adsorption type transfer mechanism, which can meet the requirement that the conveyor can be stably conveyed at any angle of arrangement.

[0045] Combined withFigure 4 , optionally, the conveying unit further includes a waste discharging mechanism 102 and a second negative pressure conveyor 103. The second negative pressure conveyor 103 is horizontally arranged, and a paddle mechanism 104 is provided at the inlet end of the second negative pressure conveyor 103 corresponding to the first negative pressure conveyor 101. The paddle mechanism 104 is adapted to dial the sheets on the second negative pressure conveyor 103 into the first negative pressure conveyor 101; the waste discharging mechanism 102 is adapted to discharge the adhered sheets on the second negative pressure conveyor 103. That is to say, the second negative pressure conveyor 103 conveys the sheets on the main machine of the conveying production line. The second negative pressure conveyor 103 is also a product conveying mechanism using vacuum adsorption, and the conveying surface for conveying the sheets is on the bottom surface. Thus, by arranging the paddle mechanism 104 at the inlet end of the second negative pressure conveyor 103 corresponding to the first negative pressure conveyor 101, the product can be dialed from the second negative pressure conveyor 103 and dropped into the first negative pressure conveyor 101 by using the paddle mechanism 104. Among them, the paddle mechanism 104 may include a paddle board and a motor. The paddle board is rotatably arranged on the side of the conveying surface of the second negative pressure conveyor 103, and the motor is connected to the paddle board to drive the paddle board to rotate for the dialing action. In addition, to prevent two adhered sheets from being sent into the sheet sorting process and unable to ensure the packaging quality, a waste discharging mechanism 102 is arranged on the second negative pressure conveyor 103. The waste discharging mechanism 102 may include a collection box, a paddle board and a motor. The paddle board is arranged on the side of the conveying surface of the second negative pressure conveyor 103, the collection box is arranged below the paddle board, and the motor is connected to the paddle board to drive the paddle board to rotate to dial the two adhered and misaligned sheets into the collection box. Among them, an electric eye may be arranged on the second negative pressure conveyor 103 to detect the phase and continuous sheets of the sanitary napkin small pieces, and the non-conforming products are discharged into the collection box.

[0046] Combined with Figure 3 , in some examples, the Hot Wheels 201 includes a wheel body and wheel claws. The wheel body has a disc-shaped structure, and a plurality of wheel claws are distributed on the outer circumference of the wheel body. A product clamping and placing space is formed between each wheel claw and the outer circumference of the wheel body. Among them, the outer contour of the wheel claw is an arc-shaped finger structure, including a connected mounting portion and a finger end. The mounting portion is fixedly connected to the wheel body, and a gap is left between the finger end and the outer circumferential surface of the wheel body. This gap is the product clamping and placing space. In order to meet the conveying requirements of the sanitary napkin product, the product clamping and placing space corresponding to each wheel claw is suitable for placing one product, and then the outlet end of the first negative pressure conveyor 101 extends to the product clamping and placing space. In addition, the finger end of the wheel claw faces the first negative pressure conveyor 101, and the Hot Wheels 201 rotates clockwise, so that the Hot Wheels 201 can stack the sheets conveyed by the first negative pressure conveyor 101 on the stacking platform 202.

[0047] In some examples, to ensure the smooth sheet sorting, a following mechanism 203 is provided on the stacking platform 202. The following mechanism 203 moves in real time along the stacking direction of the sheets as the number of sheets increases to protect the sheets.

[0048] Optionally, the following mechanism 203 includes a moving plate 2031 for protecting the sheets, a first moving driving member (not shown in the figure), and a first lifting driving member 2032. The moving plate 2031 is erected on the stacking platform 202. The first lifting driving member 2032 is connected to the moving plate 2031 to drive the lifting movement of the moving plate 2031. The first moving driving member is connected to the moving plate 2031 to drive the moving plate 2031 to move along the stacking direction of the sheets. That is to say, when the Ferris wheel 201 stacks the sheets on the stacking platform 202, in order to ensure that the sheets are stacked into an upright stack, the moving plate 2031 is required as a backrest to support the sheets. As the sheets are stacked, the moving plate 2031 can move under the action of the first moving driving member. Among them, in this embodiment, the stacked stack completed will be transferred to the transition platform 301 by the stack hooking mechanism 302. At this time, in order to ensure the smooth movement of the stack, the first lifting driving member 2032 can drive the lifting movement of the moving plate 2031 to avoid the transfer of the stack. Optionally, the first lifting driving member 2032 adopts a cylinder structure, and the first moving driving member adopts a servo motor transmission structure. The servo motor drives the first lifting driving member 2032 to move and drives the moving plate 2031 to move. In addition, in combination with Figure 7 , a through hole 204 is provided on the stacking platform 201 for the first lifting driving member 2032 to drive the lifting movement of the moving plate 2031.

[0049] In combination with Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7, in some examples, the transition platform 301 includes a first baffle 3011, a second baffle 3012, a second moving drive 3013, and a second lifting drive 3014. The first baffle 3011 and the second baffle 3012 are spaced opposite to each other and vertically arranged on the workbench surface to jointly define a receiving space for accommodating the stack. The second moving drive 3013 is connected to the first baffle 3011 to drive the first baffle 3011 to move along the stacking direction of the wafers, and the second lifting drive 3014 is connected to the second baffle 3012 to drive the second baffle 3012 to move up and down. Among them, the transition platform 301 is provided to timely clear the stack on the stacking platform 202, so that the hot wheels 201 can continuously feed and align the wafers. After the transition platform 301 receives the stack, the pusher mechanism 303 needs to push the stack into the turntable mechanism. At this time, to avoid the stack from being scattered, the transition platform 301 protects the stack by setting the first baffle 3011 and the second baffle 3012. Moreover, before the stack hook mechanism 302 transfers the stack into the transition platform 301, the first baffle 3011 can be driven by the second moving drive 3013 to move to the stacking platform 202 to support the stack instead of the moving plate 2031; it can be understood that when the stack on the stacking platform 202 is formed, the first baffle 3011 moves to the position of the moving plate 2031 to protect one side of the stack, and the moving plate 2031 descends to make way. Then, the stack hook mechanism 302 cooperates with the first baffle 3011 to transfer the stack to the transition platform 301 from the other side of the stack. After the transfer is in place, the stack hook mechanism 302 returns to the initial position, and the second baffle 3012 rises under the drive of the second lifting drive 3014 to protect the other side of the stack. In this embodiment, the second lifting drive 3014 adopts a cylinder structure, and the second moving drive 3013 adopts a servo motor drive structure.

[0050] In some examples, the stack hook mechanism 302 includes a hook 3021, a rotation drive 3022, an X-axis drive 3023, and a Z-axis drive 3024. The rotation drive 3022 is connected to the hook 3021, the moving end of the Z-axis drive 3024 is connected to the rotation drive 3022, and the moving end of the X-axis drive 3023 is connected to the Z-axis drive 3024 to drive the hook 3021 to move between the stacking platform 201 and the transition platform 301. That is to say, the stack hook mechanism 3021 drives the hook 3021 to move flexibly through the cooperation of the rotation drive 3022, the X-axis drive 3023, and the Z-axis drive 3024, so as to transfer the stack from the stacking platform 201 to the transition platform 301. Among them, the rotation drive 3022 adopts a motor structure, and the motor drives the hook 3021 to swing by rotation. The X-axis drive 3023 and the Z-axis drive 3024 can be linear slide table modules. The Z-axis drive 3024 drives the hook 3021 to move along the Z-axis direction, and the X-axis drive 3023 drives the hook 3021 to move along the X-axis direction.

[0051] Since the stack is in an upright state, when it is transferred to the transition platform 301 by the hook stacking mechanism 302, the sheets in the stack may be misaligned in the vertical direction. Therefore, in some examples, the transition platform 301 is further provided with a stack aligning mechanism 304. The stack aligning mechanism 304 includes a pressing plate 3041 and a third lifting driving member (not shown in the figure). The third lifting driving member is connected to the pressing plate 3041 to drive the pressing plate 3041 to move up and down to press down the sheets that are misaligned in the vertical direction on the transition platform 301. Among them, the pressing plate 3041 is in a U shape, and it can be inserted into the claw gap of the hook 3021 to shape the stack between the first baffle 3011 and the second baffle 3012. At the same time, it can also prevent the sheets of the stack from sticking and misaligning as the hook 3021 leaves. In this embodiment, the third lifting driving member can be a cylinder structure, and the cylinder drives the pressing plate 3041 to move up and down.

[0052] Then, after the stacking on the transition platform 301 is completed, the stacking pushing mechanism 303 operates to push the stack from the transition platform 301 into the turntable mechanism. Among them, the stacking pushing mechanism 303 can include a pushing plate 3031 and a third moving driving member 3032. The third moving driving member 3032 is connected to the pushing plate 3031 to drive the pushing plate 3031 to insert into the accommodating space to push the stack from the accommodating space into the turntable mechanism. Among them, the third moving driving member 3032 can be a linear slide table module structure.

[0053] In some examples, a plurality of conveying channels 401 are circumferentially spaced on the turntable 402. Each conveying channel 401 is jointly defined by the turntable 402 and two relatively spaced and upright plates 4011. Among them, the width of each conveying channel 401 is adjustable. Thus, by providing a plurality of conveying channels 401, the layout position of the medium bag machine can be reasonably selected, and the product can be rotated by the turntable 402 to meet the requirements of various packaging forms. Among them, the width of the conveying channel 401 is adjustable by arranging a plurality of screw holes along the width direction of the conveying channel 401 on the turntable 402, and fixing the position of the vertical plate 4011 with screws to adjust the width of the conveying channel 401.

[0054] Optionally, the turntable mechanism further includes a limiting plate 403 and a fourth lifting driving member 404. The fourth lifting driving member 404 is connected to the limiting plate 403 to drive the limiting plate 403 to move up and down to limit the stack when the stacking pushing mechanism 303 pushes the stack on the transition platform 301 into the conveying channel 401. That is to say, the limiting plate 403 can be inserted into or disengaged from the conveying channel 401 under the action of the fourth lifting driving member 404. Among them, the fourth lifting driving member 404 can adopt a cylinder structure.

[0055] In addition, at the position of the turntable mechanism corresponding to the intermediate bagging machine, there is a pusher component 405 adapted to push the stack into the intermediate bagging machine from the conveying channel 401. The pusher component 405 includes a pusher plate 4051 and a fourth moving drive 4052. The fourth moving drive 4052 is connected to the pusher plate 4051 to drive the pusher plate 4051 to move, so as to push the stack from the conveying channel 401 into the intermediate bagging machine. Among them, the fourth moving drive 4052 can be a linear slide table module structure.

[0056] Optionally, an auxiliary component 406 is further provided on the turntable mechanism. The auxiliary component 406 includes a rotating plate 4061 and a rotating plate drive 4062. The rotating plate 4061 is arranged between the conveying channel 401 and the intermediate bagging machine. The rotating plate drive 4062 is connected to the rotating plate 4061 to drive the rotating plate 4061 to rotate to protect the stack so that the stack is smoothly located at the conveying station of the intermediate bagging machine.

[0057] To better understand the present invention, the present invention will be further described in combination with the working process of the present invention.

[0058] After the control system in the present device (in this embodiment, programming is performed through the control panel. Since the programmable control system is a prior art, it will not be elaborated here) issues an instruction:

[0059] The small sanitary napkin pieces flow from the main machine into the second negative pressure conveyor 103. The phase and connection of the small pieces are detected by the photoelectric eye, and the unqualified products are discharged into the collection box. The qualified products continue to be conveyed and are dialed into the first negative pressure conveyor 101 by the dialing mechanism 104. The first negative pressure conveyor 101 uses photoelectric counting to dial the set number of small pieces into the hot wheel 201. The hot wheel 201 cooperates with the stacking platform 202 and the following mechanism 203 to stack the small pieces into a vertical stack; when the stacking is completed, the stack hook mechanism 302 moves the stack into the transition platform, and the stacking part can stack continuously; while the stack on the transition platform 301 is shaped by the whole stack mechanism 304 and pushed into the conveying channel 401 in the turntable mechanism by the stack pushing mechanism 303; after the turntable mechanism rotates the stack horizontally by 90°, it is pushed into the discharge chain of the intermediate bagging machine by the pusher component 405, that is, the work of sorting the small pieces of a stack is completed.

It ensures the continuous operation of the equipment through the above-mentioned sorting device 1, realizes full automation, and improves the efficiency of the packaging equipment.
