Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0023] As used in this application, "front", "rear", "upper", and "lower" are in accordance with the front, rear, upper, and lower shown in the attached Figure 1 ; "left" and "right" as used in this application are in accordance with the left and right shown in the attached Figure 2

[0024] In this application, unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium.

[0025] The present application provides a fully automatic centerless winding system for sheets. This fully automatic centerless winding system is used for winding sheets with relatively hard texture, and is particularly suitable for winding drainage boards. As Figures 1-3 shown, the fully automatic centerless winding system 100 includes a storage device 10, a winding device 20, and a turning device 30 arranged in sequence from upstream to downstream. The storage device 10 is used to temporarily store the sheets when the winding device 20 changes the roll. The winding device 20 is used to automatically collect the sheets into a roll and package the wound roll of the coil. The turning device 30 is used to collect and stack the packaged coils onto the same platform for unified transportation of multiple coils.

[0026] The storage device 10 includes a first frame 1 and a plurality of storage rollers 2 that can move in the vertical direction and rotate around their own axis on the first frame 1. The axis of each storage roller 2 extends in the left-right direction, and the plurality of storage rollers 2 are arranged alternately up and down from front to back. The sheets sequentially pass around the plurality of storage rollers 2 from front to back. When the winding device 20 changes the roll, the upper storage roller 2 moves upward, and the lower storage roller 2 moves downward, thereby increasing the length of the movement path of the sheets in the storage device 10 to achieve the purpose of temporarily storing the sheets; when the winding device 20 finishes winding, the upper storage roller 2 moves downward, and the lower storage roller 2 moves upward to release the sheets; the storage device 10 meets the function of the winding device 20 for online roll change. The rotational speeds of the plurality of storage rollers 2 are the same to ensure the stable conveyance of the sheets.

[0027] As Figure 4 、 5 ​As shown in FIGS. 6 and 8 , the winding device 20 is arranged at the rear side of the storage device 10, and the winding device 20 includes a second frame 3, a slitting mechanism for longitudinally slitting a plate, an auxiliary traction mechanism 5 for pulling the plate output by the storage device 10, a cross-cutting mechanism 6 for transversely cutting the plate, a winding shaft 7 rotatable around its own axis, a guide plate mechanism 8 located between the cross-cutting mechanism 6 and the winding shaft 7, an auxiliary pressing plate mechanism 9 arranged on the upper side of the guide plate mechanism 8, a tightening mechanism 11 for tightening the winding shaft 7 at one end of the winding shaft 7, and an unwinding mechanism 12 for unwinding the winding shaft 7. The slitting mechanism, the auxiliary traction mechanism 5, the cross-cutting mechanism 6 and the winding shaft 7 are arranged in sequence from front to back. After the plate is output from the storage device 10, it passes through the slitting mechanism 4 and the cross-cutting mechanism 6 in sequence under the traction of the auxiliary traction mechanism 5 and is wound on the winding shaft 7.

[0028] like Figure 8 As shown, the slitting mechanism 4 includes at least one slitting knife 41, and each slitting knife 41 can rotate around a center line extending in the left-right direction, so as to adjust the angle between the slitting knife 41 and the plate, so that the slitting mechanism 4 is suitable for plates of different specifications. A plurality of slitting knives 41 are arranged in sequence in the left-right direction, and each slitting knife 41 is configured to be able to move in the left-right direction to adjust the width of the plate slitting by the slitting knife 41 according to production requirements.

[0029] like Figure 6 , 8 As shown, the auxiliary traction mechanism 5 includes an upper traction roller 51 and a lower traction roller 52 which are arranged opposite to each other in the upper and lower directions, a pressing cylinder 53 which is transmission-connected to the upper traction roller 51, and a traction motor 54 which is transmission-connected to the lower traction roller 52. The pressing cylinder 53 is used to drive the upper traction roller 51 to move in the up and down directions; the traction motor 54 is used to drive the lower traction roller 52 to rotate around its own axis; when the winding device 20 is changing the roll, the pressing cylinder 53 drives the upper traction roller 51 to move downward to press the plate against the lower traction roller 52. At this time, the traction motor 54 stops driving the lower traction roller 52, and the upper traction roller 51 and the lower traction roller 52 are pressed together to prevent the plate from moving downstream, so as to facilitate the cross-cutting of the plate by the cross-cutting mechanism 6, ensure that the incision of the plate is smooth, and facilitate the rolling of the plate after changing the roll.

[0030] like Figure 6 , 7As shown in the figure, the cross-cutting mechanism 6 includes a cutting tool assembly 61 and a cross-cutting pressing assembly 62 located above the cutting tool assembly 61. The cutting tool assembly 61 includes a table 611 extending in the front-rear direction, a cross-cutting hob 612 capable of moving in the left-right direction, and a cross-cutting motor 613 drivingly connected to the cross-cutting hob 612. The table 611 is provided with a tool groove 6110 for at least partially exposing the cross-cutting hob 612. The cross-cutting motor 613 is used to drive the cross-cutting hob 612 to move back and forth in the left-right direction in the tool groove 6110. A chain drive is adopted between the cross-cutting motor 613 and the cross-cutting hob 612. The cross-cutting pressing assembly 62 includes a pressing block 621 and a pressing cylinder 622 for driving the pressing block 621 to approach and move away from the table 611. The bottom of the pressing block 621 is provided with a groove 6210 opposite to the tool groove 6110. The depth of the groove 6210 is greater than the height of the part of the cross-cutting hob 612 located above the table 611. When the rewinding device 20 changes the roll, after the upper traction roller 51 and the lower traction roller 52 press the sheet material, the pressing cylinder 622 drives the pressing block 621 to move downward to press the sheet material against the table 611, preventing the sheet material from moving during cross-cutting. The cross-cutting motor 613 drives the cross-cutting hob 612 to cut the sheet material from left to right. After cutting the sheet material, the pressing cylinder 622 drives the pressing block 621 to reset.

[0031] The auxiliary traction mechanism 5, the cross-cutting mechanism 6 and the storage device 10 cooperate with each other. When the production line conveys the sheet material at a high speed, changing the roll does not require stopping the machine, realizing online roll change.

[0032] As Figure 5 、 8 As shown in FIGS. 8 and 9, the axis of the rewinding shaft 7 extends in the left-right direction. The rewinding shaft 7 includes a first end 71 rotatably provided on the second frame 3 and a second end 72 suspended on the second frame 3. The first end 71 is drivingly connected to a rewinding motor 73 installed on the second frame 3. The rewinding shaft 7 rotates around its own axis under the drive of the rewinding motor 73 to wind the sheet material. The rewinding motor 73 is a servo motor to ensure constant tension winding of the sheet material. The rewinding shaft 7 is provided with an opening 74 for inserting the starting end of the sheet material.

[0033] As Figure 6 、 8As shown, the auxiliary pressing plate mechanism 9 and the guide plate mechanism 8 are pressed together between the cross-cutting mechanism 6 and the winding shaft 7 to form a guiding channel 31 that defines the moving direction of the sheet. The guide plate mechanism 8 includes a guide plate 81 and a first cylinder 82 connected to the guide plate 81. The front end of the guide plate 81 is rotatably connected to the second frame 3. The first cylinder 82 is used to drive the guide plate 81 to rotate so that the rear end of the guide plate 81 approaches and departs from the guiding channel 31. The guide plate 81 includes a pair of side plates arranged oppositely left and right, and the pair of side plates are located on the left and right sides of the guiding channel 31. The auxiliary pressing plate mechanism 9 includes a pressing plate 91, a pressing roller 92 rotatably provided at the rear end of the pressing plate 91, and a second cylinder 93 connected to the pressing plate 91. The front end of the pressing plate 91 is rotatably connected to the second frame 3. The second cylinder 93 is used to drive the pressing plate 91 to rotate so that the pressing roller 92 approaches and departs from the guiding channel 31.

[0034] A pair of alignment switches are also provided on the winding shaft 7. The alignment switches are signal-connected to the winding motor 73 and are configured to send a signal to the winding motor 73 when the opening 74 is aligned with the rear end of the guiding channel 31, causing the winding motor 73 to stop rotating. When the winding device 20 changes the winding, the first cylinder 82 drives the guide plate 81 to rotate upward, and the second cylinder 93 drives the pressing plate 91 to rotate downward, so that the pressing roller 92 presses the sheet against the guide plate 81, defining the movement of the sheet in the guiding channel 31, and accurately guiding the sheet in the guiding channel 31 to the opening 74 on the winding shaft 7, facilitating the loading of the sheet.

[0035] As Figures 4-6 shown, the tightening mechanism 11 includes a tightening cylinder 111 that tightens the winding shaft 7 by the second end 72, a swing arm 112 rotatably provided on the second frame 3, and a lifting cylinder 113 connected to the swing arm 112. The tightening cylinder 111 is provided at the rear end of the swing arm 112. The tightening cylinder 111 has a tightening position aligned with the second end 72 and a lifting position above the second end 72. The lifting cylinder 113 is used to drive the tightening cylinder 111 to switch between the tightening position and the lifting position.

[0036] As Figure 4 、 5As shown in FIGS. 9, the coil unloading mechanism 12 includes a push plate 121 and a pushing assembly 122 that is drivingly connected to the push plate 121. An opening 1210 for the winding shaft 7 to pass through is formed in the push plate 121. The diameter of the opening 1210 is larger than the diameter of the winding shaft 7 and smaller than the diameter of the coil. The pushing assembly 122 includes a guide rail 1221 extending in the left-right direction, a slider 1222 mounted at the bottom of the push plate 121, and an unloading motor 1223 that drives the push plate 121 to move along the guide rail 1221. The slider 1222 is slidably engaged with the guide rail 1221. When the clamping cylinder 111 rotates to the lifting position, the pushing assembly 122 drives the push plate 121 to move from the first end 71 to the second end 72, so as to push the coil on the winding shaft 7 away from the winding shaft 7, achieving the purpose of unloading the coil.

[0037] The coil unloading mechanism 12 further includes a transition assembly 123. The transition assembly 123 extends obliquely outward from the second end 72 to the outside of the second frame 3. The transition assembly 123 includes a plurality of transition rollers 1231, and the plurality of transition rollers 1231 are arranged downward in sequence from the second end 72 to the outside of the second frame 3.

[0038] As Figure 4 shown, an automatic tape sticking mechanism 13 is further provided at the rear side of the winding shaft 7. The automatic tape sticking mechanism 13 is used for sticking tape to the coil on the winding shaft 7. The automatic tape sticking mechanism 13 is movably arranged on the second frame 3 in the front-rear direction.

[0039] As Figure 3 、 10, as shown in FIGS. 11 and 12, the turnover device 30 is located on the side of the second frame 3 where the clamping mechanism 11 is arranged. The turnover device 30 includes a turnover frame 14 and a stacking table 15 arranged at the rear side of the turnover frame 14. The turnover frame 14 is used to receive the coil material pushed out by the uncoiling mechanism 12 and push the coil material onto the stacking table 15. The turnover frame 14 includes a third frame 141, a plurality of guide rollers 142 rotatably arranged on the third frame 141, and a plurality of lifting components 143 for lifting the coil material. The axis lines of the respective guide rollers 142 extend in the front-rear direction. The plurality of guide rollers 142 and the plurality of lifting components 143 are alternately arranged in the left-right direction. Each lifting component 143 includes a lifting plate 1431 rotatably connected to the third frame 141 and a lifting cylinder 1432 for driving the lifting plate 1431 to rotate. The rear end portion of the lifting plate 1431 is rotatably connected to the third frame 141, and the front end portion of the lifting plate 1431 is connected to the lifting cylinder 1432. When the lifting cylinder 1432 pushes the lifting plate 1431 to turn upward and the front end portion of the lifting plate 1431 is higher than the rear end portion, the coil material received by the turnover frame 14 can be pushed onto the stacking table 15. The turnover frame 14 includes a photoelectric switch 144 signal-connected to the lifting cylinders 1432 of the respective lifting components 143. In the left-right direction, there is a dimension between the end portion of the third frame 141 close to the second frame 3 and the photoelectric switch 144, and the dimension is larger than the width of the coil material. The photoelectric switch 144 is configured to control the lifting cylinder 1432 to lift the lifting plate 1431 when at least a part of the coil material is located above the photoelectric switch 144.

[0040] The stacking table 15 includes a stacking plate 151 arranged obliquely and a baffle 152 extending upward from the stacking plate 151. The stacking plate 151 has an upper end portion 1511 close to the turnover frame 14 and a lower end portion 1512 far from the turnover frame 14. The upper end portion 1511 is located above the lower end portion 1512. The baffle 152 is arranged at the lower end portion 1512 to block the downward rolling trend of the coil material on the stacking plate 151; the upper end portion 1511 is located below the lifting plate 1431 to facilitate the conveyance of the coil material from the turnover frame 14 to the stacking table 15.

[0041] A plurality of adjusting feet 145 are provided at the bottom of the third frame 141. The adjusting feet 145 are used to adjust the height of the third frame 141 to ensure that the lifting plate 1431 is located above the upper end portion 1511.

[0042] The working principle of the full-automatic centerless winding system 100 is as follows: The lifting cylinder 113 drives the swing arm 112 to rotate, so as to rotate the pressing cylinder 111 to the pressing position. The pressing cylinder 111 presses the winding shaft 7 tightly. The sheet material is wound on the winding shaft 7 after passing through the storage device 10, the slitting mechanism 4, the auxiliary traction mechanism 5 and the cross-cutting mechanism 6. When the sheet material on the winding shaft 7 is full, the upper traction roller 51 of the auxiliary traction mechanism 5 presses the sheet material tightly, and the pressing block 621 presses the sheet material downward onto the tabletop 611. The storage device 10 stores the sheet material. The cross-cutting hob 612 moves horizontally to cut the sheet material, and the pressing block 621 resets. After the winding shaft 7 completely winds the cut sheet material, the automatic tape sticking mechanism 13 moves forward. The winding motor 73 drives the winding shaft 7 to rotate one circle so that the tape provided by the automatic tape sticking mechanism 13 packs the coil material. The pressing cylinder 111 releases the winding shaft 7. The lifting cylinder 113 drives the pressing cylinder 111 to rotate to the lifting position. The pushing assembly 122 drives the push plate 121 to push the coil material off the winding shaft 7 and is pushed onto the tipping rack 14. The pressing cylinder 111 rotates to the pressing position to press the winding shaft 7 tightly. The pressing plate 91 and the guiding plate 81 are pressed together to form a guiding channel 31. The opening 74 on the winding shaft 7 is aligned with the guiding channel 31. The upper traction roller 51 moves upward to reset. The traction motor 54 drives the lower traction roller 52 to rotate. At the same time, the storage device 10 releases the stored sheet material. The sheet material inserts the starting end into the opening 74 of the winding shaft 7 through the guiding channel 31. The winding motor 73 drives the winding shaft 7 to rotate for winding. After the photoelectric switch 144 detects that the coil material pushed to the tipping rack 14 is in place, each lifting cylinder 1432 drives each lifting plate 1431 to lift, so as to push the coil material onto the stacking table 15.

[0043] This application realizes automatic loading, automatic winding, automatic packing and automatic unloading of sheet materials, with high automation degree, convenient operation, and improved production efficiency, and is especially suitable for winding drainage boards.
