Description

Technical Field

[0001] This invention relates to a tape unwinding device, a tape product manufacturing system, and a tape unwinding method. Background Technology

[0002] The content in this section only provides background information related to this invention and may not constitute prior art.

[0003] Adhesive tape, by bonding two or more unconnected objects together, is widely used in packaging, home furnishings, and the medical field. For example, in the medical field, tape is commonly used to wrap sterile gauze, catheters, dressings, etc., around the skin of a patient's wound. In medical applications, microporous tape, due to its excellent breathability, can prevent skin allergies such as redness, itching, and rashes at the tape application site, thus being widely welcomed by doctors and patients. In the manufacturing process of microporous tape, it is typically unwound from the tape roll and conveyed to a slitting device to produce various models and specifications of tape products. However, the adhesive on the tape easily overflows through the micropores, causing the microporous tape wound on the roll to easily stick together during unwinding. This leads to abrupt changes in the peel angle of the microporous tape, resulting in significant noise during unwinding and uneven tension on the tape, which in turn affects subsequent production processes and may even damage the tape, thus impacting the yield of the finished tape.

[0004] Therefore, it is hoped that the production of adhesive tape products can be improved, the unwinding process of adhesive tape can be optimized, noise can be reduced, and the yield of adhesive tape products can be increased. Summary of the Invention

[0005] One object of this invention is to reduce noise during the tape unwinding process. Another object of this invention is to avoid wrinkling of the tape, thereby improving the yield of tape products.

[0006] One aspect of the present invention is to provide a tape unwinding device. The tape unwinding device includes an unwinding shaft configured to mount a roll of tape wound with tape. The tape unwinding device further includes an unwinding control device comprising a pressure roller mounted parallel to the unwinding shaft, and the position of the pressure roller being adjustable such that the pressure roller contacts the radially outer surface of the tape roll mounted on the unwinding shaft, and the tape is peeled off from the tape roll at the contact position between the pressure roller and the tape roll.

[0007] In one embodiment, the unwinding control device further includes: a drive device configured to adjust the position of the pressure roller; and a controller configured to control the drive device.

[0008] In one embodiment, the unwinding control device further includes: a pressure roller support, the pressure roller being rotatably mounted on the pressure roller support and capable of moving together with the pressure roller support; and a transmission member, configured to connect the pressure roller support to a drive device such that the drive device drives the pressure roller toward or away from the unwinding shaft via the transmission member.

[0009] Preferably, the pressure roller can also move relative to the pressure roller support in the axial direction of the pressure roller.

[0010] In one embodiment, the pressure roller support includes: a first support arm; a second support arm arranged parallel to and spaced apart from the first support arm; and a first connecting shaft fixedly connected to a first end of the first support arm and a first end of the second support arm, and connected to a transmission member. The pressure roller is rotatably mounted between the second ends of the first and second support arms.

[0011] In one embodiment, the unwinding control device further includes a detection device configured to detect the contact pressure between the pressure roller and the tape roll. The controller controls the drive device based on the detection result from the detection device.

[0012] In one embodiment, the detection device is a pressure sensor mounted on the pressure roller.

[0013] In one embodiment, the pressure roller includes a sleeve, the position of which can be adjusted such that the sleeve contacts the radial outer surface of the tape roll mounted on the unwinding shaft.

[0014] In one embodiment, the pressure roller further includes a central shaft, the two ends of which are fixedly mounted on the pressure roller support. A sleeve is fitted onto the central shaft, and the sleeve is rotatable about the central shaft and movable along the central shaft.

[0015] Another aspect of the present invention is to provide a tape manufacturing system comprising a tape unwinding device according to the present invention.

[0016] Another aspect of the present invention is to provide a tape unwinding method, the tape unwinding method comprising: mounting a tape roll with tape wound on it to an unwinding shaft; and setting a pressure roller parallel to the unwinding shaft and adjusting the position of the pressure roller so that the pressure roller contacts the radial outer surface of the tape roll, so that the tape is peeled off from the tape roll at the contact position between the pressure roller and the tape roll.

[0017] The tape unwinding method also includes: detecting the contact pressure between the pressure roller and the tape roll, and adjusting the position of the pressure roller based on the detected contact pressure.

[0018] The tape unwinding apparatus, tape manufacturing system, and angle unwinding method according to the present invention, by setting up an unwinding control device, ensures that the pressure roller always contacts the radial outer surface of the tape roll with appropriate pressure during the tape roll unwinding process, so that the tape is always peeled from the tape roll at the contact position between the pressure roller and the tape roll, resulting in a stable peeling angle for the tape. This significantly reduces noise during the unwinding process and ensures that the unwound tape has appropriate tension. Furthermore, preferably, by enabling the pressure roller to move laterally, wrinkles in the tape can be avoided. Attached Figure Description

[0025] The following description is exemplary in nature and is not intended to limit the invention, its application, or its uses. It should be understood that in all these figures, similar reference numerals indicate the same or similar parts and features. The figures are only schematic representations of the concept and principles of embodiments of the invention and do not necessarily show the specific dimensions and scale of each embodiment. Certain parts in specific figures may be exaggerated to illustrate relevant details or structures of embodiments of the invention.

[0026] In the description of embodiments of the present invention, the directional terms related to "up," "down," "left," and "right" are used to describe the up, down, left, and right positions of the views shown in the accompanying drawings. In practical applications, the positional relationships of "up," "down," "left," and "right" used herein can be defined according to actual circumstances, and these relationships can be reversed.

[0027] Figure 1 A schematic diagram of tape unwinding according to a comparative example is shown. Figure 1 As shown, a roll of adhesive tape M with adhesive tape S wound on it is mounted on an unwinding shaft 10. Due to the adhesive on the adhesive tape S wound on the roll of tape M, adhesion occurs between the adhesive tape S and the roll of tape M during the unwinding process. This is especially true when the adhesive tape S is a microporous tape, as the tape S easily produces excess adhesive through the micropores. Therefore, in cases such as... Figure 1 As shown, when unwinding tape roll M, the diameter of tape roll M decreases as unwinding progresses. Furthermore, due to adhesive adhesion, the peeling position of tape S from tape roll M is prone to change, causing abrupt changes in the peeling angle α of tape S. This results in significant noise during unwinding, potentially damaging the operator's hearing. Therefore, in the operation of related tape unwinding devices, transparent soundproof covers are installed to reduce noise. Even then, operators often have to wear earplugs, affecting their comfort. Additionally, the abrupt changes in the peeling angle α of tape S during unwinding cause uneven tension in the unwound tape S, and even slack, which affects subsequent processing of the tape.

[0028] Figure 2 A schematic block diagram of a tape unwinding device 1 according to the present invention is shown. Figure 2 As shown, the tape unwinding device 1 includes an unwinding shaft 10. The unwinding shaft 10 is configured to hold a roll of tape wound with adhesive tape (e.g., microporous medical tape). The unwinding shaft 10 can be an active unwinding shaft or a passive unwinding shaft. Additionally, as... Figure 2 As shown, the tape unwinding device 1 also includes an unwinding control device 20. The unwinding control device 20 is configured to control the position where the tape is peeled from the tape roll during the tape unwinding process, thereby controlling the peeling angle of the tape and the tension on the unwound tape.

[0029] The unwinding control device 20 includes a pressure roller 21, a drive unit 22, a controller 23, and a detection device 24. The pressure roller 21 can be driven to move toward or away from the unwinding shaft 10. The drive unit 22 is configured to drive the pressure roller 21 toward or away from the unwinding shaft 10 to adjust the position of the pressure roller 21, thereby adjusting the contact pressure between the pressure roller 21 and the tape roll mounted on the unwinding shaft 10. The detection device 24 is configured to detect the contact pressure between the pressure roller 21 and the tape roll mounted on the unwinding shaft 10. For example, the detection device 24 can detect the contact pressure between the pressure roller 21 and the tape roll at predetermined intervals. Preferably, the detection device 24 is configured to detect the contact pressure between the pressure roller 21 and the tape roll in real time. In one example, the detection device 24 can be a pressure sensor mounted on the pressure roller 21. Alternatively, the detection device 24 can also be a position sensor that detects the relative position between the pressure roller 21 and the radial outer surface of the tape roll mounted on the unwinding shaft 10. The controller 23 is configured to receive the detection result from the detection device 24 and control the drive device 22 to drive the pressure roller 21 to move based on the detection result, so that the pressure roller 21 always contacts the tape roll with appropriate pressure, controls the position of the tape peeling off from the tape roll, so that the tape has a stable peeling angle during the unwinding process and the unwound tape has appropriate tension.

[0030] Figure 3 A partial schematic diagram of a tape unwinding device 1 according to one embodiment of the present invention is shown. Figure 4 A perspective view of the tape unwinding device 1 is shown, but the controller 23 and detection device 24 of the tape unwinding device 1 are not shown. Figure 3 and Figure 4 As shown, the unwinding shaft 10 is mounted on a mounting plate B. The mounting plate B can be a mounting plate for a tape manufacturing system. In the example shown, the unwinding shaft 10 is an active unwinding shaft with a drive unit (not shown), capable of rotating under the drive of its drive unit, thereby rotating the tape roll M mounted on the unwinding shaft 10 to unwind it. Therefore, the unwinding shaft 10 is rotatably mounted on the mounting plate B. Preferably, as... Figure 4 As shown, a bushing 11 is installed on the outer peripheral surface of the unwinding shaft 10 to facilitate a stable engagement between the unwinding shaft 10 and the roll of tape M mounted thereon, so that the tape roll M mounted on the unwinding shaft 10 can rotate integrally with the unwinding shaft 10.

[0031] like Figure 3 As shown, the unwinding control device 20 also includes a pressure roller support 25 and a transmission component 26. Figure 4 An exemplary structure of the pressure roller support 25 is shown. Figure 4As shown, the pressure roller support 25 includes a first support arm 251, a second support arm 252, and a first connecting shaft 253. The first support arm 251 and the second support arm 252 are arranged generally parallel to each other and spaced apart. The first connecting shaft 253 is located at the first end of the pressure roller support 25. Figure 3 and Figure 4 (The left end of the middle). The first end of the first support arm 251 and the first end of the second support arm 252 are both fixedly mounted to the first connecting shaft 253, so that the first support arm 251 and the second support arm 252 move integrally with the first connecting shaft 253. The first end of the pressure roller support 25 is mounted on the mounting plate B, while the second end of the pressure roller support 25 is suspended. Specifically, as Figure 4 As shown, the first connecting shaft 253 located at the first end of the pressure roller support 25 is rotatably mounted to the mounting plate B, such that the pressure roller support 25 is rotatably mounted on the mounting plate B and can rotate about the axis of the first connecting shaft 253. For example, in one example, one end of the first connecting shaft 253 can pass through a mounting through hole on the mounting plate B. Figure 4 (Not shown in the image) and is rotatably supported on mounting plate B.

[0032] The pressure roller support 25 is connected to the output shaft of the drive unit 22 via the transmission member 26. In one example, the drive unit 22 can be a cylinder. Alternatively, the drive unit 22 can also be a hydraulic cylinder or a motor. Figure 3 As shown, the transmission component 26 includes a first transmission component 261 and a second transmission component 262. The drive device 22 and the transmission component 26 ( Figure 4 (Not shown) It is mounted to the back of mounting plate B. One end of the first transmission member 261 is mounted to the output shaft of the drive device 22, and the opposite end of the first transmission member 261 is hinged to the second transmission member 262. The second transmission member 262 can be a rigid crank. One end of the second transmission member 262 is hinged to the first transmission member 261, and the opposite end of the second transmission member 262 is fixedly connected to the first connecting shaft 253 of the pressure roller support member 25. With the above arrangement, the second transmission member 262 and the pressure roller support member 25 can move integrally.

[0033] The pressure roller 21 is supported by the pressure roller support 25 parallel to the unwinding shaft 10 and connected to the output shaft of the drive device 22 via the transmission member 26. The pressure roller 21 is rotatably mounted at the second end of the pressure roller support 25 and can move integrally with the pressure roller support 25. Specifically, as Figure 4As shown, the pressure roller 21 is mounted between the second end of the first support arm 251 and the second end of the second support arm 252, parallel to the unwinding shaft 10. The axial length of the pressure roller 21 is set to be greater than the width of the tape roll M to be unwound. The pressure roller 21 is supported by the pressure roller support 25 and can move integrally with the pressure roller support 25 and the second transmission member 262. The pressure roller 21 can also rotate about its axis, so that during the tape unwinding process, as the tape is unwound and conveyed to the downstream processing device, the pressure roller 21 can rotate accordingly, avoiding resistance to the tape. In one example, the pressure roller 21 includes a central shaft (…). Figure 3 and Figure 4 (Not shown) and sleeve 211, the two ends of which are respectively fixed to the second end of the first support arm 251 and the second end of the second support arm 252. The sleeve 211 is sleeved on the central shaft and can rotate about the central shaft. The position of the pressure roller 21 can be adjusted such that the sleeve 211 contacts the radial outer surface of the tape roll M mounted on the unwinding shaft. The length of the sleeve 211 is greater than the width of the tape roll M. Preferably, as shown... Figure 4 As shown, the pressure roller support 25 also includes a second connecting shaft 254 to more stably connect the first support arm 251 and the second support arm 252, thereby providing more stable support for the pressure roller 21.

[0034] When unwinding the tape roll M, first install the tape roll M on the unwinding shaft 10, and then wrap the tape S wound on the tape roll M around the pressure roller 21, as follows. Figure 3 As shown in the figure. Then, the position of the pressure roller 21 is adjusted by the unwinding control device 20 so that the pressure roller 21 contacts the radial outer surface of the tape roll M mounted on the unwinding shaft 10 with appropriate pressure, thereby controlling the position of the tape S unwinding from the tape roll M and adjusting the contact pressure between the pressure roller 21 and the tape roll M.

[0035] Specifically, when the detection device 24 ( Figure 3 and Figure 4 When the detection results (not shown) indicate that the pressure roller 21 is not in contact with the radial outer surface of the tape roll M or the contact pressure between the pressure roller 21 and the radial outer surface of the tape roll M is insufficient, the controller 23 ( Figure 3 and Figure 4 (Not shown in the image) The drive unit 22 is controlled such that the output shaft of the drive unit 22 moves along... Figure 3 As shown, C1 extends outwards, so the output shaft of the drive device 22, via the first transmission member 261, causes the second transmission member 262 to rotate around the axis of the first connecting shaft 253 along... Figure 3 The roller supports 25 rotate in the direction indicated by arrow D1, thereby causing them to rotate around the axis of the first connecting shaft 253. Figure 3Rotating in the direction indicated by arrow E1 causes the pressure roller 21 to move toward the unwinding shaft 10, so as to contact the radial outer surface of the tape roll M mounted on the unwinding shaft 10 with appropriate pressure, clamping the tape S wound on the tape roll M between the tape roll M and the pressure roller 21. As the unwinding shaft 10 rotates along... Figure 3 The roller 21 rotates in the direction indicated by arrow A1, causing the tape roll M to rotate. The tape S is peeled off from the tape roll M, which in turn causes the pressure roller 21 to rotate. During unwinding, the diameter of the tape roll M gradually decreases as unwinding progresses. However, if insufficient contact pressure is detected between the pressure roller 21 and the radial outer surface of the tape roll M due to the decrease in the diameter of the tape roll M, the pressure roller 21 is driven to move toward the unwinding shaft 10. Therefore, through the above-described arrangement of the unwinding control device 20, the pressure roller 21 always contacts the radial outer surface of the tape roll M with appropriate pressure, ensuring that the tape S is always peeled off from the tape roll M at the contact position P between the pressure roller 21 and the tape roll M. Thus, the peeling angle of the tape does not change abruptly during unwinding, and the unwound tape S is conveyed downstream via the pressure roller 21, for example, to a downstream processing device, where the tape S can have appropriate tension.

[0036] On the other hand, when the detection device 24 detects that the contact pressure between the pressure roller 21 and the tape roll M is too high or that unwinding needs to be stopped, the controller 23 controls the drive device 22 to make the output shaft of the drive device 22 move along... Figure 3 As shown, direction C2 retracts, and thus the output shaft of drive device 22, via first transmission member 261, causes second transmission member 262 to revolve around the axis of first connecting shaft 253 along... Figure 3 The roller supports 25 rotate in the direction indicated by arrow D2, thereby causing them to rotate around the axis of the first connecting shaft 253. Figure 3 Rotating in the direction indicated by arrow E2 causes the pressure roller 21 to move away from the unwinding shaft 10, thereby reducing the contact pressure between the pressure roller 21 and the tape roll M mounted on the unwinding shaft 10, or preventing the pressure roller 21 from contacting the tape roll M.

[0037] Therefore, during the unwinding process, the pressure roller 21 can always contact the radial outer surface of the tape roll M mounted on the unwinding shaft 10 with appropriate pressure. The tape is always unwound from the tape roll M at the contact position P between the pressure roller 21 and the tape roll M. The peel angle of the tape is stable and does not jump, which can significantly reduce the noise during the unwinding process and ensure that the unwound tape S has appropriate tension and moves along the... Figure 3 The direction indicated by arrow A2 in the image is used to transport the material downstream, which is beneficial for downstream processing.

[0038] Preferably, the pressure roller 21 is also configured to be able to move laterally relative to the pressure roller support 25, that is, to move along the axial direction of the pressure roller 21, such as... Figure 4As indicated by arrow X in the diagram. This arrangement allows the pressure roller 21 to slide accordingly when the lateral position of the tape S conveyed from the tape unwinding device 1 is adjusted downstream of it, thereby preventing wrinkles in the tape S wrapped around the pressure roller 21. In this example, the pressure roller 21 may be configured to include a central shaft and a sleeve 211 fitted onto the central shaft. The two ends of the central shaft are fixed to the second ends of the first support arm 251 and the second support arm 252, respectively. The length of the sleeve 211 is less than the distance between the second ends of the first support arm 251 and the second support arm 252, allowing the sleeve 211 to rotate about the central shaft and also move along it. The sleeve 211 may be a stainless steel sleeve. Alternatively, the sleeve 211 may be a brass sleeve or other suitable forms. Alternatively, the pressure roller 21 may also be configured to include only the sleeve and not the aforementioned central shaft. In this configuration, the two ends of the sleeve can be respectively fitted onto protruding shanks located at the second ends of the first support arm 251 and the second ends of the second support arm 252. In one example, the protruding shank is the shank of a bolt that is installed at the second ends of the first support arm 251 and the second ends of the second support arm 252. Alternatively, the protruding shank is a protrusion integrally provided at the second ends of the first support arm 251 and the second ends of the second support arm 252.

[0039] The tape unwinding apparatus 1 and tape unwinding method according to the first embodiment of the present invention have been described above. By providing the unwinding control device 20 in the tape unwinding apparatus 1, during the unwinding process of the tape roll M, the position of the pressure roller 21 is adjusted so that the pressure roller 21 always contacts the radial outer surface of the tape roll M with appropriate pressure. The tape S wound on the tape roll M is always unwound from the tape roll M at the contact position P between the pressure roller 21 and the tape roll M, so that the tape has a stable peel angle without jumping, which can significantly reduce the noise during the unwinding process. In the operation of the tape unwinding apparatus 1 according to the present invention, a satisfactory noise reduction effect can be achieved without the need for a soundproof cover. In a comparative test between a tape unwinding apparatus of the related art and the tape unwinding apparatus 1 according to the present invention, a soundproof cover of plexiglass was installed on the tape unwinding apparatus of the related art, while the tape unwinding apparatus 1 according to the present invention did not have a soundproof cover and the measured noise was lower than that measured on the tape unwinding apparatus of the related art. Furthermore, the tape S unwound by the tape unwinding device 1 according to the present invention has appropriate tension, which is beneficial for subsequent processing, such as subsequent die-cutting. Preferably, by configuring the pressure roller 21 to be able to move laterally (along the axial direction of the pressure roller 21) relative to the pressure roller support 25, wrinkles in the tape S can be avoided during lateral position correction.

[0040] Figure 5A schematic block diagram of an example of a tape manufacturing system 100 equipped with a tape unwinding device 1 according to the present invention is shown. Figure 5 In the example shown, the tape manufacturing system 100 is an infusion patch die-cutting system. The tape manufacturing system 100 includes a tape unwinding device 1 according to the present invention, and further includes multiple processing devices disposed downstream of the tape unwinding device 1, namely a tape alignment device 2, a die-cutting device 3, a bonding device 4, a packaging device 5, and a conveying device 6. The tape unwinding device 1 is configured to unwind a roll of microporous medical tape and convey the unwound microporous medical tape to the downstream processing devices. The tape alignment device 2 is used to correct the lateral position of the unwound tape. The die-cutting device 3 is configured to die-cut the unwound tape into multiple tape strips of predetermined width, and to cut each tape strip into tape blocks of suitable size. The bonding device 4 is configured to bond a backing layer to the side of the tape on which the adhesive is disposed. In one example, the laminating device 4 can be integrated into the die-cutting device 3, such that after the unwound tape is die-cut into multiple tape strips, a backing layer is laminated to the adhesive side of each tape strip, and then the tape strips with the backing layer are die-cut into tape blocks of appropriate size to manufacture an infusion patch of predetermined size. The packaging device 5 is configured to package the die-cut infusion patches, for example, by packaging one or more cut infusion patches into a packaging bag to produce an infusion patch product. The conveying device 6 is configured to convey the manufactured infusion patch product to a downstream product receiving station. Alternatively, the tape product manufacturing system 100 can also be other types of tape product manufacturing systems, which may include only a portion of the above-described processing devices, or may include other processing devices.

[0041] The foregoing has illustrated exemplary embodiments of a tape unwinding apparatus and a tape product manufacturing system equipped with the tape unwinding apparatus according to preferred embodiments of the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described and illustrated above. Various modifications and variations can be made to the present invention by those skilled in the art without departing from its spirit and scope. All such modifications and variations fall within the scope of the present invention. Furthermore, all components described herein can be replaced by other technically equivalent components.
