[0032] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where 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.

[0033] To better understand the above technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying 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 completely conveyed to those skilled in the art.

[0034] The following will Figures 1 - 5 describe in detail the implementation of a stacking device provided by the present invention.

[0035] A stacking device 1 according to an embodiment of the first aspect of the present invention includes a conveying unit, a stacking unit, and a discharging unit. The conveying unit is disposed above the stacking unit to convey single sheets conveyed by the conveying unit to the stacking unit for stacking to form a stack, and the discharging unit is disposed below the stacking unit to receive the stack and transfer the stack out of the stacking unit.

[0036] The stacking unit includes a plurality of pallets 101 and two vertically arranged circulating conveyors 102. The plurality of pallets 101 are arranged at intervals on the conveying surfaces of the two circulating conveyors 102. Among them, two pallets 101 on the same horizontal plane and on the opposite sides of the two circulating conveyors 102 jointly define a stacking platform. The top of the stacking unit has a feeding port A, and its bottom has a discharging port B. A sheet deflecting mechanism 201 is provided on the conveying unit. The sheet deflecting mechanism 201 is adapted to deflect the sheets on the conveying unit into the feeding port A according to a set quantity to stack and form a stack on the stacking platform at the feeding port A; wherein, the stacking platform carrying the stack moves down in real time as the number of sheets increases to transport the stack to the discharging port B, and a new stacking platform is formed at the feeding port A. The discharging unit is disposed at the discharging port B to receive the stack on the stacking platform and transfer the stack to the medium packaging machine.

[0037] Among them, the sheets can be small sanitary napkin pieces, and the stacking device 1 is disposed between the main machine of the production line of small sanitary napkin pieces and the medium packaging machine. After the small sanitary napkin pieces are stacked into a stack by the stacking device 1, they are sent to the packaging machine for packaging. The stack stacked by the stacking device 1 is a horizontal stack formed by continuously stacking small sanitary napkin pieces from the feeding port A on the stacking platform.

[0038] Therefore, according to the stacking device 1 of the present invention, through the cooperation of the multiple stacking platforms formed by the two circulating conveyors 102 and the plurality of pallets 101 on the stacking unit, when a group of stacks is stacked at the feeding port A, the stack moves down, a new stacking platform is formed, and sheets can continue to be stacked on the new stacking platform. The equipment does not need to pause, realizing the full automation of the packaging equipment and improving the packaging efficiency.

[0039] Combined with Figure 1 and Figure 2, in some examples, the conveying unit includes a horizontally arranged negative pressure conveyor 202 and a waste discharging mechanism 203, and the bottom surface of the negative pressure conveyor 202 is the conveying surface.

[0040] Specifically, the negative pressure conveyor 202 conveys the sheets on the main machine of the conveying production line. The negative pressure conveyor 202 is a product conveying mechanism using vacuum adsorption. The negative pressure conveyor 202 may 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 closely attached to the air suction box. Conveying the small sanitary napkin pieces through the vacuum adsorption type conveying mechanism can meet the requirement that the conveying surface is arranged on the bottom surface of the negative pressure conveyor 202 and still can stably convey. Thus, a dialing mechanism 201 is arranged at the feeding port A corresponding to the stacking part on the negative pressure conveyor 202, and the dialing mechanism 201 can be used to dial the product from the negative pressure conveyor 202 and drop it into the feeding port A. Among them, the dialing mechanism 201 may include a second dialing plate 2011 and a first rotation driving part 2012. The second dialing plate 2011 is rotatably arranged on the side of the conveying surface of the negative pressure conveyor 202, and the first rotation driving part 2012 is connected to the second dialing plate 2011 to drive the second dialing plate 2011 to rotate and dial the sheets on the conveying surface down. In this embodiment, the first rotation driving part 2012 may be a motor structure.

[0041] In addition, to prevent two adhered and misaligned sheets from being sent to the sheet sorting and thus unable to ensure the packaging quality, a waste discharging mechanism 203 is arranged on the negative pressure conveyor 202. The waste discharging mechanism 203 includes a first dialing plate 2031 arranged on the side of the conveying surface, a collection box 2032 arranged below the conveying surface, and a second rotation driving part (not shown in the figure) connected to the first dialing plate 2031. The first dialing plate 2031 is adapted to dial the adhered sheets on the conveying surface into the collection box 2032, and the second rotation driving part is connected to the first dialing plate 2031 to drive the first dialing plate 2031 to rotate and dial the two adhered and misaligned sheets into the collection box 2032. Among them, an electric eye may be arranged on the negative pressure conveyor 202 to detect the phase and continuous sheets of the small sanitary napkin pieces, and the unqualified products are discharged into the collection box 2032. In this embodiment, the second rotation driving part may be a motor structure.

[0042] Combined Figure 3 , in some examples, a roller 103 and a baffle 104 are arranged at the feeding port A. The roller 103 and the baffle 104 are arranged at intervals and oppositely. The surface of the baffle 104 opposite to the roller 103 and the rolling surface of the roller 103 jointly define a guiding channel C. The guiding channel C is connected to the dialing end of the dialing mechanism 201 to guide the sheets dialed by the dialing mechanism 201 from the guiding channel C to the stacking table at the feeding port A. That is to say, the guiding channel C is an inclined channel. The sheets can slide into the stacking table due to inertia through the roller 103, and the baffle 104 can prevent the sheets from being scattered during stacking on the stacking table.

[0043] Optionally, an arc-shaped plate 105 is provided on the side of the roller 103, and the arc surface of the arc-shaped plate 105 is flush with the rolling surface of the roller 103, so as to ensure that the sheets can be stacked on the stacking table along the guiding channel C when being pushed down.

[0044] Optionally, the surface of the baffle 104 opposite to the roller 103 is an arc surface, whereby the guiding channel C can be an inclined channel, ensuring that the sheets can be stacked on the stacking table along the guiding channel C when being pushed down, and further ensuring that the stacks on the stacking table will not be scattered.

[0045] Combined Figure 4 and Figure 5 In some examples, the circulating conveyor 102 includes a support 1021 and a pulley assembly mounted on the support 1021, and the distance between the two supports 1021 is adjustable. Specifically, the pulley assembly includes a driving wheel roller 1022, a driven wheel roller 1023 and a conveyor belt 1024. The two ends of the driving wheel roller 1022 are fixed to the upper end of the support 1021 through two bearings 1025, the driven wheel roller 1023 is pivotally connected to one end of the support 1021 away from the driving wheel roller 1022, the conveyor belt 1024 is wound around the driving wheel roller 1022 and the driven wheel roller 1023, and the conveyor belt 1024 uses a synchronous belt structure in this embodiment. Then, a plurality of pallets 101 are vertically fixed on the conveyor belt 1024, and two pallets 101 on the two conveyor belts 1024 of the two circulating conveyors 102 that are in the same horizontal plane and on the opposite sides can support the stack; thus, when the conveyor belt 1024 moves in a cycle, the stacking table can move accordingly, so that during stacking, the stacking table can move downward following the increase in the number of sheets to complete the stacking action, move the stack to the discharge port B, and form a new stacking table at the feeding port A. Among them, the cyclic movement of the conveyor belt 1024 is driven by a transmission structure of a synchronous pulley, a synchronous belt and a motor connected to the driving wheel roller 1022.

[0046] In addition, the two supports 1021 are assembled together through sliders, guide rails and adjustment knobs. In this way, by adjusting the adjustment knob to make the slider slide on the guide rail, the distance between the two pallets 101 on the stacking table can be adjusted according to the size of the stack, so that the stacking table is suitable for the sizes of various stacks.

[0047] In some examples, the discharging part includes a moving support 301 and a moving driving member 302. The moving support 301 is arranged at the discharge port B to receive the stack on the stacking table, and the moving driving member 302 is connected to the moving support 301 to drive the moving support 301 to move so as to transfer the stack to the medium bag machine.

[0048] Optionally, there is a gap between the two pallets 101 on the stacking table. Thus, at the discharge port B, the stacking table separates as the two pallets 101 move in a cycle, and the stack can fall into the moving support 301, without interference between the moving support 301 and the pallet 101. In this embodiment, the moving driving member 302 is a structure of a motor-driven linear slide group, and the moving driving member 302 drives the moving support 301 to move between the inlet of the tundish machine and the discharge port B to transfer the stack.

[0049] To better understand the present invention, the present invention will be further described in combination with the working process of the present invention.

[0050] After the control system in the 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:

[0051] The small pieces of sanitary napkins flow from the main machine into the negative pressure conveyor 202. The phase and connection of the small pieces are detected by the photoelectric eye, and the non-conforming products are discharged into the collection box 2032. The conforming products continue to be conveyed and are dialed into the feed port A by the dialing mechanism 201. The negative pressure conveyor 202 uses photoelectric counting to dial a set number of small pieces into the feed port A. The stacking table at the feed port A moves down in real time to cooperate with the guiding channel C to stack the small pieces into a horizontal stack; when the stacking is completed, the stack continues to move down, and a new stacking table is formed at the feed port A, and the stacking part can stack continuously; while at the discharge port B, the moving support 301 receives the stack and is pushed into the discharge chain of the tundish machine under the drive of the moving driving member 302, that is, the stacking work of one stack is completed.
