Description

[Technical field]

[0001] The present invention relates to a transport device for an electrode double-wrapped device and an electrode double-wrapped device including the same.

[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2021-0136368 filed on October 14, 2021 and Korean Patent Application No. 10-2021-0140177 filed on October 20, 2021, and all contents disclosed in the documents of said Korean patent applications are incorporated herein by reference. [Background technology]

[0003] In general, after production, the electrodes are wound into an electrode roll, packaged in a packaging bag, and shipped as a final product.

[0004] Here, the electrode rolls were packaged using a double packaging technique in which the primary and secondary packaging was done in packaging bags made of different materials to improve storage stability by preventing not only the penetration of foreign objects but also the penetration of moisture and damage to the appearance.

[0005] Meanwhile, in the process of transporting the electrode rolls that had completed the primary packaging to the secondary packaging location, a part of the packaging bag was pinched or caught by the transport device or peripheral equipment, causing the packaging bag to tear or the equipment to break.

[0006] Generally, the transfer device of the electrode double packaging device transfers the electrode roll placed on it to the packaging location. In the case of a primary packaged electrode roll, the packaging bag comes into contact with the placement part of the transfer device, and the packaging bag that comes into contact with the placement part during the contact or transportation process is often torn. To solve this problem, a rubber pad is introduced to the placement part.

[0007] The rubber pads wear out after a certain period of use and must be replaced, but it is not easy to immediately detect and replace the worn-out rubber pads, and in fact, there is a problem in that the productivity of the product is reduced because the time to replace the rubber pads is determined based on the damage to the product caused by the worn-out rubber pads. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention aims to provide a transport device for an electrode double packaging apparatus, which can prevent a part of a primary packaging bag from being pinched or caught by a transport device or a peripheral device in the process of transporting an electrode roll that has completed primary packaging to a secondary packaging location, and an electrode double packaging apparatus including the same.

[0009] Another object of the present invention is to provide an electrode packaging device that can detect wear of the rubber pads of a transfer device provided on the placement portion of a primarily packaged electrode roll and notify the user when it is time to replace the rubber pads, thereby preventing damage to packaging bags caused by worn rubber pads.

[0035] Throughout the specification, when a part "comprises" a certain component, this does not mean excluding other components, but may further include other components, unless otherwise specified. In addition, throughout the specification, when a part is "connected" or "coupled" to another part, this includes not only "directly connected" or "directly coupled" but also "connected with other components in between."

[0036] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. In addition, in the drawings, parts that are not related to the description are omitted in order to clearly explain the present invention, and similar parts are designated by similar reference numerals throughout the specification.

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] FIG. 1 is a diagram showing an exemplary transport device 1 for an electrode double-packaging device according to the present invention, FIG. 2 is a diagram for explaining the structure of a primarily packaged electrode roll, and FIG. 3 to FIG. 5 are diagrams for explaining the operating principle of the transport device.

[0039] The present invention relates to a transfer device 1 of an electrode double packaging device that primarily packages an unpackaged electrode roll in a first packaging bag and secondarily packages the primarily packaged electrode roll in a second packaging bag. For example, the transfer device 1 may be a device that transfers the electrode roll that has been primarily packaged to a secondary packaging location.

[0040] 1 to 3, the transfer device 1 includes a placement unit 100, a packaging bag arrangement unit 700, a movement unit 500, and a control unit 600.

[0041] The mounting part 100 has a mounting groove 110 on which the primarily packaged electrode roll is to be mounted.

[0042] The moving unit 500 is provided to move the placement unit 100, and the moving unit 500 may be configured with a known driving unit such as a hydraulic cylinder, a pneumatic cylinder, or a motor.

[0043] The control unit 600 is configured to control the moving unit 500 to perform a placing mode in which the placing unit 100 is moved so that the electrode roll is placed in the placing groove 110, and a transport mode in which the placing unit 100 on which the electrode roll is placed is transported to a secondary packaging location.

[0044] The packaging bag sorting unit 700 is provided to move together with the placing unit 100 by the moving unit 500, and is provided to bring the first packaging bags 20 into close contact with the electrode roll placed in the placing groove 110 when moving. That is, the packaging bag sorting unit 700 functions to sort the first packaging bags 20 so that the first packaging bags 20 come into close contact with the electrode roll placed in the placing groove 110 when moving. The packaging bag sorting unit 700 is connected to the placing unit 100, and may have a plate shape, for example.

[0045] The control unit 600 may be configured to control the moving unit 500 to perform a placement mode in which the moving unit 500 moves so that an electrode roll is placed in the placement groove 110, and a transfer mode in which the electrode roll placed on the placement unit 100 is transferred to a second packaging location. The control unit 600 may control the moving unit 500 to sequentially perform the placement mode and the transfer mode. The moving unit 500, the placement unit 100, and the packaging bag sorting unit 700 may be connected to one another. As a result, the placement unit 100 and the packaging bag sorting unit 700 may move together in the moving direction of the moving unit 500. The control unit 600 may also control the moving unit 500 to perform a separation mode in which the moving unit 500 separates the electrode roll from the placement unit 100. The separation mode may be performed after the moving unit 500 arrives at the second packaging location.

[0046] 2, the electrode roll may include a body 11 around which electrodes are wound, a pair of support plates 12 formed on both sides of the body 11, and protrusions 13 formed to protrude from the center of each support plate in a direction opposite to the body 11. The body 11 may be, for example, cylindrical, and the support plate 12 may be formed to have a diameter larger than that of the body 11. The support plate 12 functions to prevent the electrodes wound around the body 11 from coming off to the outside.

[0047] In addition, the mounting groove 110 is provided so that the protrusion 13 of the electrode roll is placed thereon, and by placing the protrusion 13 inside the mounting groove 110, the protrusion 13 can be prevented from escaping outside the mounting groove 110 during the transport process.

[0048] In addition, the primarily packaged electrode roll is completely surrounded by a first packaging bag 20, and an edge 22 of the first packaging bag 20 is located around the support plate 12. The edge 22 of the first packaging bag 20 refers to a portion that protrudes outward without being in close contact with the electrode roll 10. In the present application, a packaging bag sorting unit 700 serves to sort the edge 22 of the first packaging bag.

[0049] In the placement mode, the packaging bag sorting unit 700 is provided so as to bring the edge 22 of the first packaging bag 20 located around the support plate 12 of the electrode roll into close contact with the support plate 12. The edge 22 of the first packaging bag 20 refers to the portion that does not come into close contact with the support plate 12 and bulges outward from the support plate 12.

[0050] The edge 22 of the first packaging bag 20 may cause problems such as getting caught or pinched by peripheral devices or a transport device during the transport mode. The packaging bag sorting unit 700 can prevent pinching problems in advance by sorting the edge 22 of the first packaging bag 20 in the placement mode, which is a step prior to the transport mode.

[0051] Furthermore, the above-mentioned placement mode may include a first movement mode in which the placement portion 100 is moved in a first direction F1 so that the placement groove 110 is positioned at the lower end of the protrusion 13 of the electrode roll, and a second movement mode in which the placement portion 100 is moved in a second direction F2 that is perpendicular to the first direction F1 so that the lower end of the protrusion 13 of the electrode roll is placed on the placement groove 110.

[0052] In addition, during the first movement mode, the packaging bag sorting section 700 can be configured to move along the first direction F1 on the upper end side of the protrusion 13, and push the edge of the first packaging bag located at the upper end of the protrusion 13 toward the support plate 12.

[0053] 3 and 4, in the first movement mode, the packaging bag sorting unit 700 may move along the first direction F1 on the upper end side of the protruding portion 13. The packaging bag sorting unit 700 may be arranged vertically to face the placement unit 100 across the protruding portion 13. The packaging bag sorting unit 700 may bring the edge of the first packaging bag 20 located around the support plate 12 of the electrode roll along the first direction F1 on the upper end side of the protruding portion 13 into close contact with the support plate 12.

[0054] In addition, in the first movement mode, the packaging bag sorting unit 700 may be configured to move at a predetermined distance d from the support plate 12.

[0055] In the first movement mode, edge 22 of the first packaging bag located around support plate 12 can be accommodated in space S formed by distance d between packaging bag sorting unit 700 and support plate 12. That is, in the first movement mode, the portion of the first packaging bag pressed toward support plate 12 by packaging bag sorting unit 700 can be accommodated in space S formed by distance d between packaging bag sorting unit 700 and support plate 12.

[0056] When executing the placement mode, the control unit 600 can control to execute the second movement mode after executing the first movement mode. In the first movement mode, the placement unit 100 and the protruding portion 13 are not in contact with each other, and in the second movement mode, the protruding portion 13 is placed on the placement groove 110.

[0057] In addition, the transport device 1 for the electrode double packaging device may include a mounting pad 200 provided in the mounting groove 110, a wear detection sensor 300 that detects wear on the mounting pad 200, and a notification unit 400 that notifies the user of the need to replace the pad when wear on the mounting pad 200 is detected by the wear detection sensor.

[0058] The mounting pad 200 is provided in the mounting groove 110 on which the protruding portion 13 of the primary packaged electrode roll is placed. Thus, the mounting pad 200 has a mounting surface on which the protruding portion 13 of the electrode roll is placed. The wear detection sensor 300 detects wear of the mounting pad 200. The notification unit 400 notifies the user of the need to replace the pad when wear of the mounting pad 200 is detected by the wear detection sensor 300.

[0059] Furthermore, the control unit 600 can control the operation of the moving unit 500 depending on whether or not the wear detection sensor 300 detects wear on the mounting pad 200 .

[0060] The mounting pad 200 may be made of a different material than the mounting groove 110. As an example, the mounting pad 200 may be a rubber pad made of a rubber material.

[0061] The transfer device 1 according to the present application can prevent the problem of the packaging bag being torn due to the worn rubber pad 200 by notifying the time to replace the rubber pad 200 (mounting pad 200) through the wear detection sensor 300 and the notification unit 400. The wear detection sensor 300 can be, for example, a laser sensor.

[0062] The wear detection sensor 300 is provided to recognize the placement surface of the rubber pad 200 that is not worn. When the rubber pad 200 is worn, the wear detection sensor 300 fails to recognize the placement surface and generates an error. The wear detection sensor 300 is also provided to recognize at least a partial area of ​​the rubber pad 200. Since the wear detection sensor 300 is provided to recognize at least a partial area of ​​the rubber pad 200, if a new rubber pad is not attached by mistake (pad omission) during the process of replacing the worn rubber pad 200 with a new rubber pad, at least a partial area of ​​the rubber pad 200 is not recognized and an error occurs.

[0063] When such an error occurs, the notification unit 400 can notify the user in a visual and audible manner that it is time to replace the wear pad.

[0064] The wear detection sensor 300 may also include a laser sensor.

[0065] In addition, the control unit 600 may be configured to interrupt the execution of the placement mode and the transfer mode of the moving unit 500 when wear of the rubber pad 200 is detected by a laser sensor.

[0066] The control unit 600 controls the operation of the moving unit 500, so that an operator can safely replace the wear pads.

[0067] For example, when wear of the rubber pad 200 is detected by the wear detection sensor 300, the control unit 600 can suspend the execution of the placement mode and the transfer mode of the moving unit 500. Furthermore, by suspending the placement mode and the transfer mode of the moving unit 500, the entire process of the packaging device can be suspended. This is to prevent products with packaging bags torn due to worn rubber pads from being shipped as final products.
