[0002] This application claims the priority and benefit of Korean Patent Application No. 10 - 2023 - 0170743, filed on November 30, 2023, the disclosure of which is incorporated herein by reference in its entirety. Background Art 1. Technical Field

[0003] The present invention relates to a device for automatically removing a finishing tape attached to a winding roll of a film member.

[0004] 2. Related Technology Discussion

[0005] Figure 12 is a configuration diagram of a general winding roll of a film member. As Figure 12 illustrated, a film member 11 such as a separator of a secondary battery is wound around a bobbin and manufactured and supplied in the form of a winding roll 10. In this case, a finishing tape 13 (hereinafter referred to as "finishing tape") is attached to the end portion 12 of the film member of the winding roll 10 of the film member to prevent unwinding. The finishing tape 13 is formed in any of various forms, and as Figure 12 illustrated, a barcode is printed on the finishing tape to record product information. Therefore, in order to use the winding roll 10 of the film member provided in this way for a specific process, the finishing tape 13 should be removed. For example, in order to use the separator, the finishing tape 13 should be removed before installing the separator winding roll on a corresponding reel. Since the separator is made of a vinyl - like material, the finishing tape 13 is in close contact with the separator. Therefore, a sharp tool is used to remove the finishing tape 13, and the removal of the finishing tape is performed manually, which may cause cutting accidents.

[0033] Figure 1 is a perspective view of a device for automatically removing a finishing tape attached to a film member winding roll according to an embodiment of the present invention; Figure 2 is at another angle Figure 1 perspective view of; Figure 3 is Figure 1 rear perspective view of; Figure 4 is Figure 1 plan view of; Figure 5 is Figure 1 front view of; Figure 6 is an illustration Figure 5 view of the state where the cover in is removed; and Figure 7 is Figure 2 perspective view of the state where the conveying assembly in is separated.

[0034] Referring to Figures 1 to 7 , a device for automatically removing a finishing tape attached to a film member winding roll according to an embodiment of the present invention includes a finishing tape removal assembly 200.

[0035] The finishing tape removal assembly 200 includes a mounting frame portion 210, a tape mounting portion 220, a separation and removal portion 230, and a tape collection portion 240.

[0036] As an implementation example, the installation frame part 210 can be formed in an L shape. The installation frame part 210 is installed such that the tape installation part 220, the separation and removal part 230, and the tape recovery part 240 can rotate upward.

[0037] The tape installation part 220 is rotatably installed on one side of the installation frame part 210, and the separation and removal tape roller 20 is installed on the tape installation part. The tape installation part 220 is equipped with the separation and removal tape roller 20. When the wound separation and removal tape 21 is pulled out, the adhesive surface of the separation and removal tape 21 faces outward, and the separation and removal tape 21 is conveyed by the surface friction between the separation and removal tape 21 and the conveying part 231 of the separation and removal part 230.

[0038] The tape installation part 220 is connected to a third driving part 255 for rotating and driving the tape installation part 220 at the rear surface of the installation frame part 210, and performs a rotation operation by driving the third driving part 255. In addition, an example in which the driving part is a driving motor is described in this implementation example, but the present invention is not limited thereto, and various modifications are possible.

[0039] The separation and removal part 230 is arranged at a distance from the tape installation part 220, and guides the driving while rotating, so that the separation and removal tape 21 of the separation and removal tape roller 20 installed on the tape installation part 220 is pulled out and collected and wound on the tape collection part 240. The separation and removal part 230 makes the adhesive surface of the separation and removal tape 21 face outward, and attaches the adhesive surface to the adjacent finishing tape 13 of the film member winding roller 10 to separate the finishing tape 13 from the film member 11. The separation and removal part 230 is installed adjacent to the tape installation part 220.

[0040] The separation and removal part 230 includes a conveying part 231 having a specific liner and at least one support member formed inside the conveying part 231 to support the conveying part 231 and provide a rotational force. An example in which the conveying part 231 is a continuous tape is described in this implementation example, but the present invention is not limited thereto, and various modifications using one roller are also possible. The support member may include a first support part 232 and a second support part 233 formed at two inner ends of the conveying part 231 and a third support part 234 located below the first support part 232 and the second support part 233. An example in which the support member is a roller is described in this implementation example, but the present invention is not limited thereto, and various modifications are possible.

[0041] The first support part 232 and the second support part 233 are connected to the rotating shaft of the second driving part 250 through a first power transmission unit 253 and a second power transmission unit 254, and are configured to rotate jointly with the rotational drive of the second driving part 250. An example in which the power transmission unit is a power conveyor belt is described in this implementation example, but the present invention is not limited thereto, and various modifications are possible.

[0042] At least one of the conveying unit 231 and the at least one support member may have a gasket. That is, various modifications are possible. For example, only the conveying unit 231 may have a gasket, only the at least one support member may have a gasket, or both the conveying unit 231 and the at least one support member may have a gasket.

[0043] As an implementation, the conveying unit 231 may be made of silicone or rubber and have a specific gasket, and apply a frictional force to the separation removal belt 21 that is conveyed while in contact with the surface, so that the separation removal belt 21 is easily conveyed to the belt collection unit 240. In addition, the conveying unit 231 is disposed near a part of the first support unit 232 that protrudes toward one side, and contacts a part of the finishing belt 13 of the rotary film member winding roller 10 with a specific pressure.

[0044] In this way, a specific pressure and contact configuration of a part of the first support unit 232 toward the outside of the conveying unit 231 provide the result that the adhesive surface of the separation removal belt 21 that is conveyed while in contact with the surface of the conveying unit 231 is attached to the finishing belt 13 of the film member winding roller 10.

[0045] The belt collection unit 240 is installed near the separation removal unit 230, and collects the separation removal belt 21 to which the finishing belt 13 introduced through the separation removal unit 230 is attached.

[0046] The belt collection unit 240 is rotatably installed on the installation frame unit 210, is connected to the rotary shaft of the second driving unit 250 on the rear surface of the installation frame unit 210, and is rotationally driven at a constant rotational speed and constant torque through a speed reducer 251 and a torque limiter 252.

[0047] By driving the second driving unit 250, the first support unit 232 and the second support unit 233 of the separation removal unit 230 and the belt collection unit 240 rotate jointly with each other.

[0048] Figure 8 is a view of the separation removal belt installed according to an implementation of the present invention; and Figures 9 to 11 is an enlarged configuration diagram of the separation removal unit for describing the operating state of the present invention.

[0049] As Figures 8 to 10 illustrated, the conveying unit tension support unit 236 and the belt tension support unit 237 are rotatably installed on the installation frame unit 210.

[0050] The tape removal assembly 200 may further include a coupling frame portion 211 located below the mounting frame portion 210. The coupling frame portion 211 may be mounted on the rail 140 of the base assembly 100 formed therebelow and moved a predetermined distance. The coupling frame portion 211 includes a rail mounting portion 212 formed on the bottom surface of the coupling frame portion and disposed on the rail 140 of the base assembly 100, and one side of the coupling frame portion is connected to the direction changing portion 130 of the base assembly 100.

[0051] According to an embodiment of the present invention, the apparatus for automatically removing the finishing tape attached to the film member winding roller may further include a base assembly 100. The base assembly 100 is configured to move the tape removal assembly 200 a predetermined distance. The base assembly 100 includes: a first driving portion 110 formed on one side of the base assembly; a rotating screw 120 that rotates in place by driving the first driving portion 110; a direction changing portion 130 mounted on the rotating screw 120, the other side of the direction changing portion being fixed to the coupling frame portion 211 of the tape removal assembly 200, and the direction changing portion converting the rotational motion of the rotating screw 120 into a linear motion and moving the coupling frame portion 211 according to the linear motion; and a pair of rails 140 on which the rail mounting portion 212 of the tape removal assembly 200 is disposed. The reference numeral 111 not described is a speed reducer, and the reference numerals 121 and 122 not described are supports for the rotating screw 120.

[0052] When the first driving portion 110 rotates forward, the rotating screw 120 is driven to rotate forward, so that the base assembly 100 formed in this way moves the direction changing portion 130 to the left as Figure 5 illustrated, so that the separation and removal portion 230 of the tape removal assembly 200 approaches the film member winding roller 10 (not illustrated). In contrast, when the first driving portion 110 is driven to rotate in the reverse direction, the rotating screw 120 rotates in the reverse direction, so that the base assembly 100 moves the direction changing portion 130 to the right as Figure 5 illustrated and returns the tape removal assembly 200 to its original position.

[0053] Reference will be made to Figures 8 to 11 the operation and effects of the apparatus for automatically removing the finishing tape attached to the film member winding roller according to the embodiment of the present invention as described above.

[0054] First, the separation and removal tape roller 20 is mounted on the tape mounting portion 220 of the tape removal assembly 200, the end of the separation and removal tape 21 is drawn out and held on the conveying portion 231 with the adhesive surface facing outward, and then the end is fixedly wound on the tape collecting portion 240.

[0055] When the separation and removal belt roller 20 is removed as Figure 8 and Figure 9 illustrated in the fully installed state, the drive base assembly 100 moves the finishing belt removal assembly 200 to the side surface where the film member winding roller 10 is located. That is, when the first drive unit 110 is driven to rotate forward, the rotating screw 120 rotates forward, so the direction changing unit 130 moves the finishing belt removal assembly 200 to the position where the film member winding roller 10 is located, as Figure 10 illustrated.

[0056] When the separation and removal part 230 of the finishing belt removal assembly 200 contacts the film member winding roller 10, the first drive unit 110 stops to stop the movement of the finishing belt removal assembly 200, and the second drive unit 250 and the third drive unit 255 are driven. Therefore, the belt mounting part 220 and the belt collecting part 240 are rotationally driven, and the conveying part 231 of the separation and removal part 230 also rotates in conjunction with the rotational drive.

[0057] According to the rotation of the conveying part 213, the separation and removal belt 21 is drawn out from the belt mounting part 220 and is collected and wound onto the belt collecting part 240.

[0058] Meanwhile, the film member winding roller 10 starts to rotate in the direction opposite to that of the conveying part 231, and when the adhesive surface of the separation and removal belt 21 adheres to the finishing belt 13 of the film member winding roller 10, the finishing belt 13 is separated from the film member 11 and is guided to the belt collecting part 240 through the conveying part 231 while adhering to the separation and removal belt 21. In this case, as Figure 11 illustrated, when the finishing belt removal assembly 200 is spaced apart from the film member winding roller 10, the film member 11 attached to the finishing belt 13 is cut by a cutting device (not illustrated). Therefore, the finishing belt 13 is wound onto the belt collecting part 240 while adhering to the separation and removal belt 21, and the film member winding roller 10 is in a state where the finishing belt 13 is removed, stops rotating, and is moved for other processes.

[0059] In an embodiment of the present invention, in the film member winding roller 10 on which a film member such as a secondary battery separator is wound on a spool, since the finishing belt 13 attached to the end 12 of the film member 11 is automatically separated and removed, the process automation efficiency can be improved, cutting accidents that occur when removing a barcode belt according to the prior art can be prevented, and labor costs can be reduced.

[0060] According to the present invention, in a film member winding roller on which a film member such as an electrode roller or a separator is wound on a spool, the finishing belt attached to the end of the film member is automatically separated and removed, so the process automation efficiency can be improved, accidents such as cutting that occur when removing the finishing belt using a conventional method can be prevented, and labor costs can be reduced.

[0061] In addition, the present invention can achieve a completely unmanned automatic material exchange for secondary battery winding machines and capacitor winding machines.

[0062] Although the present invention has been described with reference to the embodiments shown in the drawings, the description is merely illustrative, and those skilled in the art to which the present technology pertains can understand that various modifications and other equivalent embodiments can be made. Therefore, the true technical scope of the present invention should be determined by the appended claims.
