Description

Technical Field

[0001] This invention relates to the field of multi-station take-up and unwinding, and more specifically, to a multi-station take-up and unwinding device. Background Technology

[0002] A conventional dual-station take-up and unwinding device requires two motors to be placed on two plates respectively. The two motors are connected to two pairs of expansion shafts on the plates respectively. In order to allow the expansion shafts to extend into or out of the corresponding overroll sleeves, the two plates need to be slidably connected to a set of brackets. The drive unit used to drive the plates to slide is connected to the turntable. Then, another set of motors set on the frame drives the turntable to rotate, so that the plates can be rotated, thereby allowing the two pairs of expansion shafts connected to the plates to exchange positions and realize the roll change.

[0003] Although the above-mentioned winding and unwinding device can realize the position swapping of two pairs of expansion shafts at two workstations to achieve the roll changing operation, it has a complex structure, high cost and large space occupation. Summary of the Invention

[0040] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0041] The following is combined Figures 1 to 10 The multi-station winding and unwinding device 10 provided in this embodiment will be described in detail.

[0042] Please refer to Figure 1 as well as Figure 2An embodiment of the present invention provides a multi-station winding and unwinding device 10, including a flipping shaft 100, a plate 110, a first expansion shaft 200, a second expansion shaft 210, a first sleeve 220, a second sleeve 230, a first driving member 240, and a second driving member 250. The plate 110 is fixed on the flipping shaft 100, which drives the plate 110 to rotate during rotation. The first expansion shaft 200 and the second expansion shaft 210 are axially movable and circumferentially rotatable on the plate 110, and are spaced apart on the plate 110. The first sleeve 220 and the second sleeve 230 are rotatably sleeved on the flipping shaft 100. The first driving member 240, the first sleeve 220, and the first expansion shaft 200 are sequentially connected, and the first driving member 240 drives the first expansion shaft 200 to rotate. The second driving member 250, the second sleeve 230, and the second expansion shaft 210 are sequentially connected, and the second driving member 250 drives the second expansion shaft 210 to rotate.

[0043] Reference Figure 1 as well as Figure 2 In this embodiment, the multi-station winding and unwinding device 10 further includes a third driving member 300 and a fourth driving member 310; both the third driving member 300 and the fourth driving member 310 are fixed on the plate 110. The third driving member 300 is connected to the first expansion shaft 200 and is used to drive the first expansion shaft 200 to move axially. The first expansion shaft 200 is always connected to the first sleeve 220 during the axial movement. The fourth driving member 310 is connected to the second expansion shaft 210 and is used to drive the second expansion shaft 210 to move axially. The second expansion shaft 210 is always connected to the second sleeve 230 during the axial movement.

[0044] Reference Figure 1 There are two plates 110, which are fixed side-by-side with a gap on the flip shaft 100. During the rotation of the flip shaft 100, the two plates 110 rotate synchronously, causing the expansion shafts on the plates 110 to rotate synchronously. There are four expansion shafts, including a third and a fourth. The first and second expansion shafts 200 and 210 are mounted on one plate 110, while the third and fourth expansion shafts are mounted on another plate 110. The third expansion shaft corresponds to the first expansion shaft 200, and the fourth expansion shaft corresponds to the second expansion shaft 210. Figure 2 The relative positions of the two shafts are described below. From top to bottom on the left, the fourth and third expansion shafts are the second and third expansion shafts, respectively. From top to bottom on the right, the second expansion shaft 210 and the first expansion shaft 200 are the second expansion shaft 210 and the first expansion shaft 200, respectively.

[0045] The third expansion shaft and the first expansion shaft 200 are used to install the roller sleeve, and the fourth expansion shaft and the second expansion shaft 210 are also used to install the roller sleeve. The third expansion shaft and the first expansion shaft 200 can move closer to each other, and the fourth expansion shaft and the second expansion shaft 210 can also move closer to each other to facilitate the insertion or removal of the roller sleeve. After the third expansion shaft and the first expansion shaft 200 are inserted into the roller sleeve, the first expansion shaft 200 rotates, causing the roller sleeve to rotate. Similarly, after the fourth expansion shaft and the second expansion shaft 210 are inserted into the roller sleeve, the second expansion shaft 210 rotates, causing the roller sleeve to rotate.

[0046] The first driving member 240 drives the first sleeve 220 to rotate, and the first sleeve 220 drives the first expansion shaft 200 to rotate. The second driving member 250 drives the second sleeve 230 to rotate, and the second sleeve 230 drives the second expansion shaft 210 to rotate. During the rotation of the first sleeve 220 and the second sleeve 230, the flip shaft 100 does not rotate. The rotation of the first expansion shaft 200 and the second expansion shaft 210 does not interfere with the rotation of the flip shaft 100.

[0047] The third driving member 300 and the fourth driving member 310 are respectively used to drive the first expansion shaft 200 and the second expansion shaft 210 to move axially to insert or withdraw from the roller sleeve. During the axial movement of the first expansion shaft 200 and the second expansion shaft 210, the first expansion shaft 200 and the second expansion shaft 210 are always connected to the first driving member 240 and the second driving member 250. That is, during the insertion or withdrawal of the first expansion shaft 200 or the second expansion shaft 210 from the roller sleeve, the rotation structure of the first expansion shaft 200 and the second expansion shaft 210 is not affected. After insertion, the first driving member 240 or the second driving member 250 drives the first expansion shaft 200 or the second expansion shaft 210 to rotate. The rotation of the first sleeve 220 and the second sleeve 230 do not interfere with each other. The first driving member 240 drives the first expansion shaft 200 to rotate, and the second driving member 250 drives the second expansion shaft 210 to rotate without interference.

[0048] The third driving member 300 and the fourth driving member 310 are fixed on the plate 110. When the flipping shaft 100 rotates to drive the plate 110 to rotate, it drives the first expansion shaft 200 and the second expansion shaft 210 to rotate around the flipping shaft 100, thereby realizing the position swapping of the first expansion shaft 200 and the second expansion shaft 210. During the rotation of the first expansion shaft 200 and the second expansion shaft 210 with the plate 110, the transmission connection between the first expansion shaft 200 and the first driving member 240 and the third driving member 300 is not interfered with, and the transmission connection between the second expansion shaft 210 and the second driving member 250 and the fourth driving member 310 is not interfered with. The multi-station take-up and unwinding device 10 also includes a flipping driving member 120, which is connected to the flipping shaft 100 and is used to drive the flipping shaft 100 to rotate.

[0049] As described above, the rotation, axial movement, and positional interchange of the first expansion shaft 200 and the second expansion shaft 210 can be achieved without simultaneously setting up a turntable and a plate, simplifying the structure and improving efficiency. Compared to traditional dual-station winding and unwinding devices, this integrates the plate 110 and the turntable, eliminating at least one set of plate 110, while retaining the effectiveness of existing dual-station winding and unwinding devices. This improves upon the existing winding and unwinding devices that require separate turntables and plate 110 for non-stop roll changing, resulting in complex structures and high costs.

[0050] Reference Figure 1 as well as Figure 2 In this embodiment, the multi-station take-up and unwinding device 10 further includes a first gear 400, a second gear 410, a third gear 420, a fourth gear 430, a first transmission belt 440, and a second transmission belt 450. The first gear 400 is fixed on the first sleeve 220, the second gear 410 is fixed on the first expansion shaft 200, and the first transmission belt 440 is wound around the first gear 400 and the second gear 410.

The third gear 420 is fixed on the second sleeve 230, the fourth gear 430 is fixed on the second expansion shaft 210, and the second transmission belt 450 is wound around the third gear 420 and the fourth gear 430. The fourth gear 430 is used to always mesh with the second transmission belt 450 during the axial movement with the second expansion shaft 210.

[0051] The first gear 400 is coaxially fixed to the first sleeve 220, and the second gear 410 is coaxially fixed to the first expansion shaft 200. During the rotation of the first sleeve 220 around the tilting shaft 100 driven by the first driving member 240, the second gear 410 and the first expansion shaft 200 are driven to rotate via the first transmission belt 440. Similarly, the third gear 420 is coaxially fixed to the second sleeve 230, and the fourth gear 430 is coaxially fixed to the second expansion shaft 210. The second driving member 250 drives the second sleeve 230 to rotate, and the fourth gear 430 and the second expansion shaft 210 are driven to rotate via the second transmission belt 450. The rotations of the first sleeve 220 and the second sleeve 230 do not interfere with each other, and the first gear 400 and the third gear 420 are arranged side-by-side along the axial direction of the tilting shaft 100.

[0052] Reference Figure 1 as well as Figure 2In this embodiment, the multi-station winding and unwinding device 10 further includes a fifth gear 500, a sixth gear 510, a third transmission belt 520, and a fourth transmission belt 530; the fifth gear 500 is fixed on the first sleeve 220, the sixth gear 510 is fixed on the second sleeve 230, the fifth gear 500 is connected to the first driving member 240 via the third transmission belt 520, and the sixth gear 510 is connected to the second driving member 250 via the fourth transmission belt 530; the first sleeve 220 is rotatably sleeved on the flipping shaft 100, and the second sleeve 230 is rotatably sleeved on the first sleeve 220; the first gear 400 and the fifth gear 500 are respectively fixed at both ends of the first sleeve 220, the third gear 420 and the sixth gear 510 are respectively fixed at both ends of the second sleeve 230, and the third gear 420 and the sixth gear 510 are arranged between the first gear 400 and the fifth gear 500.

[0053] The multi-station winding and unwinding device 10 also includes a seventh gear and an eighth gear; the seventh gear is fixed to the first driving member 240, and the seventh gear is connected to the fifth gear 500 via a third transmission belt 520; the eighth gear is fixed to the second driving member 250, and the eighth gear is connected to the sixth gear 510 via a fourth transmission belt 530.

[0054] The first driving component 240, the seventh gear, the fifth gear 500, the first sleeve 220, the first gear 400, and the second gear 410 are sequentially connected in a transmission manner, driving the first expansion shaft 200 to rotate. The second driving component 250, the eighth gear, the sixth gear 510, the second sleeve 230, the third gear 420, and the fourth gear 430 are sequentially connected in a transmission manner, driving the second expansion shaft 210 to rotate.

[0055] The two ends of the first sleeve 220 extend relative to the two ends of the second sleeve 230, and the first gear 400 and the fifth gear 500 are fixed to the two ends of the first sleeve 220 that extend relative to the second sleeve 230. In other embodiments, the first sleeve 220 may be sleeved on the second sleeve 230, with the two ends of the second sleeve 230 extending relative to the first sleeve 220, and the third gear 420 and the sixth gear 510 may be disposed at the two ends of the second sleeve 230 that extend relative to the first sleeve 220.

[0056] In this embodiment, the multi-station winding and unwinding device 10 further includes a first limiting member and a second limiting member fixed on the plate 110; the first limiting member is provided with a first channel extending along the conveying direction of the first transmission belt 440, the first channel being used to accommodate and limit the first transmission belt 440; the second limiting member is provided with a second channel extending along the conveying direction of the second transmission belt 450, the second channel being used to accommodate and limit the second transmission belt 450.

[0057] The second gear 410 is always engaged with the first transmission belt 440 during axial movement, and the fourth gear 430 is always engaged with the second transmission belt 450 during movement. To prevent the first transmission belt 440 and the second transmission belt 450 from shifting axially, a first limiting member and a second limiting member are provided to restrict the axial movement of the first transmission belt 440 and the second transmission belt 450. During the axial movement of the second gear 410 and the fourth gear 430, the axial positions of the first transmission belt 440 and the second transmission belt 450 are not affected. This prevents the position of the first transmission belt 440 in the axial direction from shifting with the movement of the second gear 410.

The fourth sleeve 610 is rotatably sleeved on the first expansion shaft 200 and fixed to the first cutting element 630. The first swing arm gear 620 is fixed on the fourth sleeve 610. The first swing arm gear 620 is used to engage or disengage with the first transmission belt 440 during the axial movement of the first expansion shaft 200. When the first swing arm gear 620 is engaged with the first transmission belt 440, it drives the first cutting element 630 to rotate to cut the material roll.

[0059] When the roller sleeve on the first expansion shaft 200 completes the winding and unwinding, the first expansion shaft 200 moves axially, driving the first swing arm gear 620 to mesh with the first transmission belt 440. The first transmission belt 440 drives the fourth sleeve 610 to rotate, which in turn drives the first cutting element 630 to rotate, completing the cutting of the material roll and realizing automatic roll changing. When the material roll does not need to be cut, the first transmission belt 440 is connected to the second gear 410 on the third sleeve 600.

[0061] When the roller sleeve on the second expansion shaft 210 completes the winding and unwinding, the second expansion shaft 210 moves axially, driving the second swing arm gear 640 to mesh with the second transmission belt 450. The second transmission belt 450 drives the sixth sleeve to rotate, which in turn drives the second cutting element 650 to rotate, completing the cutting of the material roll and realizing automatic roll changing. When the material roll does not need to be cut, the second transmission belt 450 is connected to the fourth gear 430 on the fifth sleeve. The rotation of the second expansion shaft 210 does not interfere with the sixth sleeve, the sixth sleeve does not rotate, and the second cutting element 650 remains stationary.

[0062] Reference Figure 1 as well as Figure 2 In this embodiment, the multi-station winding and unwinding device 10 further includes a first tensioning wheel 700 and a second tensioning wheel 710; the first tensioning wheel 700 and the second tensioning wheel 710 are movably disposed on the plate 110. The first tensioning wheel 700 is used to engage or disengage with the first transmission belt 440 during movement, and the second tensioning wheel 710 is used to engage or disengage with the second transmission belt 450 during movement.

[0063] The first tensioning pulley 700 can move up and down under the action of the driving component. During the axial movement of the first rocker arm gear 620 on the first expansion shaft 200, the first tensioning pulley 700 moves away from the first transmission belt 440, reducing the pressure of the first transmission belt 440 on the first rocker arm gear 620. After the first rocker arm gear 620 completes its position adjustment, the first tensioning pulley 700 moves closer to the first transmission belt 440, maintaining tension on the first transmission belt 440 and driving the first rocker arm gear 620 to rotate. The second tensioning pulley 710 functions similarly, used during the axial position adjustment of the second rocker arm gear 640, and will not be described further.

[0064] Reference Figure 1 , Figure 2 as well as Figure 4 In this embodiment, the third driving member 300 includes a first telescopic driving member 800, a first driving shaft 810, and a first push-pull plate 820; the first telescopic driving member 800 is fixed on the plate 110, the first push-pull plate 820 is fixed to the first expansion shaft 200, the first driving shaft 810 connects the first telescopic driving member 800 and the first push-pull plate 820, and the first telescopic driving member 800 is used to drive the first push-pull plate 820 and the first expansion shaft 200 to move axially.

[0065] The structure of the fourth driving member 310 is the same as that of the third driving member 300, and will not be described again here. The axial movement of the third and fourth expansion shafts can also be driven axially using the above structure. The fourth driving member 310 includes a second telescopic driving member, a second driving shaft, and a second push-pull plate; the second telescopic driving member is fixed to the plate 110, the second push-pull plate is fixed to the second expansion shaft 210, and the second driving shaft connects the second telescopic driving member and the second push-pull plate. The second telescopic driving member is used to drive the second push-pull plate and the second expansion shaft 210 to move axially.

[0066] Specifically, the multi-station winding and unwinding device 10 also includes a connecting shaft 260. A first expansion shaft 200 is coaxially fixed with the connecting shaft 260, and the first expansion shaft 200 is located inside the plate 110. The connecting shaft 260 passes through the plate 110. A third sleeve 600 is fixed on the connecting shaft 260, and a fourth sleeve 610 is rotatably sleeved on the connecting shaft 260. A first push-pull plate 820 is fixed to one end of the connecting shaft 260 located outside the plate 110. During the axial movement of the first push-pull plate 820, it drives the connecting shaft 260 and the first expansion shaft 200 to move axially.

[0067] Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 as well as Figure 10 In this embodiment, the multi-station winding and unwinding device 10 further includes a limiting drive member 900 and a limiting block 910; the limiting block 910 is provided with a slot 911, the limiting drive member 900 is connected to the limiting block 910, and the limiting drive member 900 is used to drive the limiting block 910 to move closer to or away from the plate body 110; the plate body 110 is provided with a first locking block 920 corresponding to the first expansion shaft 200 and a second locking block 930 corresponding to the second expansion shaft 210, the first locking block 920 is used to engage with the slot 911 when the first expansion shaft 200 is rotated to the position, and the second locking block 930 is used to engage with the slot 911 when the second expansion shaft 210 is rotated to the position.

[0068] In the initial state, the first locking block 920 is inserted into the slot 911. When the plate 110 needs to be rotated, the limiting drive component 900 drives the limiting block 910 away from the plate 110, the first locking block 920 disengages from the slot 911, and the plate 110 can rotate. After the plate 110 is rotated into position with the flipping shaft 100, the limiting drive component 900 can drive the limiting block 910 to move closer to the plate 110, so that the second locking block 930 is placed into the slot 911. Even if the flipping shaft 100 does not precisely rotate to the preset angle, the plate 110 can be accurately positioned by guiding and correcting the first locking block 920 or the second locking block 930 through the slot 911.

[0069] Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 as well as Figure 10 In this embodiment, the multi-station take-up and unwind device 10 further includes a first ball bearing assembly 921 and a second ball bearing assembly 931; the first ball bearing assembly 921 is fixed on the first locking block 920 and is used to guide the first locking block 920 into the locking slot 911; the second ball bearing assembly 931 is disposed on the second locking block 930 and is used to guide the second locking block 930 into the locking slot 911.

[0070] Specifically, the first roller group includes two rollers, which are fixed to the first locking block 920. The first roller group is used to reduce the friction between the first locking block 920 and the locking groove 911, and guide the first locking block 920 into the locking groove 911, thereby correcting the rotational position of the plate 110. Similarly, the second roller group also includes two rollers.

[0071] According to the multi-station winding and unwinding device 10 provided in this embodiment, the working principle of the multi-station winding and unwinding device 10 is as follows: a first sleeve 220 is sleeved on the outer periphery of the flipping shaft 100, and a second sleeve 230 is sleeved on the outer periphery of the first sleeve 220. A first driving member 240 and a second driving member 250 are respectively connected to the first sleeve 220 and the second sleeve 230 through a first transmission belt 440 and a second transmission belt 450, thereby driving the first expansion shaft 200 and the second expansion shaft 210 to rotate. The flipping driving member 120 drives the flipping shaft 100 to rotate to flip the plate 110, thereby exchanging the positions of the two pairs of expansion shafts and realizing winding and unwinding without stopping the machine.

[0072] The multi-station winding and unwinding device 10 provided in this embodiment has at least the following advantages:

[0073] The first driving component 240 drives the first sleeve 220 to rotate, which in turn drives the first expansion shaft 200 to rotate. The second driving component 250 drives the second sleeve 230 to rotate, which in turn drives the second expansion shaft 210 to rotate. During the rotation of the first sleeve 220 and the second sleeve 230, the flip shaft 100 does not rotate. The rotation of the first expansion shaft 200 and the second expansion shaft 210 does not interfere with the rotation of the flip shaft 100. This achieves non-stop winding and unwinding, improving upon the existing winding and unwinding devices that require separate turntables and plate bodies 110 for non-stop winding and unwinding operations, resulting in complex structures and high costs. Compared to traditional dual-station winding and unwinding devices, this integrates the plate body 110 and the turntable, eliminating at least one set of plate bodies 110, while retaining the effectiveness of existing dual-station winding and unwinding devices.

[0074] The third driving member 300 and the fourth driving member 310 are respectively used to drive the first expansion shaft 200 and the second expansion shaft 210 to move axially to insert or withdraw from the roller sleeve. During the process of the first expansion shaft 200 or the second expansion shaft 210 inserting or withdrawing from the roller sleeve, the rotation structure of the first expansion shaft 200 and the second expansion shaft 210 is not affected.

[0075] In addition, the first swing arm gear 620 is sleeved on the outer periphery of the third sleeve 600, and the third sleeve 600 is connected to the first cutting element 630. The first swing arm gear 620 can engage or disengage from the first transmission belt 440 under the drive of the third driving element 300. When the first swing arm gear 620 is engaged with the first transmission belt 440, the first cutting element 630 can swing with the rotation of the third sleeve 600, thereby cutting the material roll, realizing the cutting of the old material roll and achieving the effect of automatic roll changing.

[0076] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
