Description

Technical Field

[0001] The present invention relates to a conveying device for a double-electrode packaging device and an electrode double-packaging device comprising the conveying device.

[0002] This application claims priority to 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, the disclosures of which are incorporated herein by reference in their entirety. Background Art

[0003] Generally, an electrode is manufactured and then packaged in a packaging bag in a state of being wound on an electrode roll and shipped as a final product.

[0004] Here, in order to improve storage stability (eg, prevent moisture and foreign matter penetration, or prevent appearance damage), a double packaging technology of performing primary packaging and secondary packaging using packaging bags of different materials is applied to packaging of the electrode roll.

[0005] Meanwhile, when conveying the electrode roll after primary packaging to the secondary packaging position, there is a problem that a portion of the packaging bag is caught or stuck in the conveying device or peripheral devices, thereby tearing the packaging bag or causing the device to malfunction.

[0006] Typically, the conveyor device of a double electrode packaging device is used to transport the electrode roll to the packaging position in a set state. In the case of a single-packaged electrode roll, the packaging bag contacts the set portion of the conveyor device, and the packaging bag often tears during contact with the set portion or during transport. To solve this problem, a rubber gasket is introduced into the set portion.

[0007] Since rubber gaskets wear out after a certain period of use, they need to be replaced. However, even if the rubber gasket is worn out, it is not easy to detect and replace it immediately. In fact, since the replacement time of the rubber gasket is determined based on the damage to the product caused by the wear of the rubber gasket, there is a problem of reduced product productivity. Summary of the Invention

[0043] Hereinafter, examples of the present invention will be described in detail with reference to the accompanying drawings so that a person having ordinary knowledge in the technical field to which the present invention pertains can easily implement them. However, the present invention can be embodied in various forms and is not limited to the examples described herein. However, in order to clearly explain the present invention in the drawings, parts not relevant to the description have been omitted, and similar reference numerals are attached to similar parts throughout this specification.

[0044] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0045] Figure 1 is a diagram showing an exemplary conveying device (1) for an electrode double packaging device according to the present invention, Figure 2 is a diagram for explaining the structure of a primary packaged electrode roll, and Figures 3 to 5 It is a diagram for explaining the operating principle of the conveying device.

[0046] The present invention relates to a conveying device (1) for an electrode double packaging device, which is used to primarily package an unpackaged electrode roll with a first packaging bag and to secondarily package the primary packaged electrode roll with a second packaging bag. For example, the conveying device (1) may be a device for conveying an electrode roll on which primary packaging has been completed to a secondary packaging position.

[0047] refer to Figures 1 to 3 The conveying device (1) includes a placement portion (100), a packaging bag arrangement portion (700), a moving portion (500) and a control portion (600).

[0048] The placement portion (100) has a placement groove (110), and the placement groove (110) is used to place the electrode roll packaged once.

[0049] In addition, the moving part (500) is provided to move the seating part (100), and the moving part (500) may be composed of a known driving part (eg, an oil hydraulic cylinder, a pneumatic cylinder, or a motor).

[0050] The control unit (600) is configured to execute a placement mode and a conveying mode, wherein the placement mode is used to control the moving unit (500) to move the placement unit (100) so that the electrode roll is placed in the placement groove (110), and the conveying mode is used to convey the placement unit (100) with the electrode roll placed thereon to a secondary packaging position.

[0051] The packaging bag arranging unit (700) is configured to move together with the seating unit (100) via the moving unit (500), and is configured to tightly attach the first packaging bag (20) to the electrode roll seated on the seating groove (110) during movement. That is, the packaging bag arranging unit (700) performs the following function: when moving, it arranges the first packaging bag (20) so that the first packaging bag (20) is tightly attached to the electrode roll seated on the seating groove (110). The packaging bag arranging unit (700) is connected to the seating unit (100), and in one example, it may have a plate shape.

[0052] The control unit (600) can be configured to execute a placement mode and a conveying mode, wherein the placement mode is used to control the moving unit (500), whereby the electrode roll moves to be placed in the placement groove (110), and the conveying mode is used to convey the placement unit (100) on which the electrode roll is placed to the secondary packaging position. The control unit (600) can control the moving unit (500) to execute the placement mode and the conveying mode in sequence. In addition, the moving unit (500), the placement unit (100) and the packaging bag placement unit (700) can be connected to each other. Therefore, the placement unit (100) and the packaging bag placement unit (700) can move together in the moving direction of the moving unit (500). In addition, the control unit (600) can control the moving unit (500) to execute a separation mode in which the electrode roll is separated from the placement unit (100). The separation mode can be executed after reaching the secondary packaging position.

[0053] refer to Figure 2 The electrode roll may include: a body (11) on which the electrode is wound; a pair of support plates (12) formed on both sides of the body (11); and a protrusion (13) formed to protrude from the center of each support plate in a direction opposite to the body (11). The body (11) may have a cylindrical shape, for example, and the support plate (12) may be formed to have a diameter larger than that of the body (11). The support plate (12) is functionally used to prevent the electrode wound on the body (11) from escaping to the outside.

[0054] Moreover, the seating groove (110) is configured so that the protruding portion (13) of the electrode roll is seated in the seating groove, and since the protruding portion (13) is seated in the seating groove (110), the protruding portion (13) can be prevented from escaping to the outside of the seating portion (100) during transportation.

[0055] Furthermore, the electrode roll packaged once is completely surrounded by the first packaging bag (20), and the edge portion (22) of the first packaging bag (20) is located around the support plate (12). The edge portion (22) of the first packaging bag (20) is a portion that protrudes outward and does not make close contact with the electrode roll (10). In the present application, the packaging bag arrangement portion (700) is used to arrange the edge portion (22) of the first packaging bag.

[0056] In addition, in the placement mode, the packaging bag placement unit (700) is arranged so that the edge portion (22) of the first packaging bag (20) located around the support plate (12) of the electrode roll is closely attached to the support plate (12). The edge portion (22) of the first packaging bag (20) means a portion that is raised to protrude to the outside of the support plate (12) and is not closely attached to the support plate (12).

[0057] The edge portion (22) of the first packaging bag (20) may cause a problem of being stuck or caught in a peripheral device or a conveying device during the conveying mode. The packaging bag arranging unit (700) can prevent the entrapment problem in advance by arranging the edge portion (22) of the first packaging bag (20) in the placement mode (which is a step before the conveying mode).

[0058] Moreover, the placement mode may include: a first movement mode, in which the placement portion (100) moves in a first direction (F1) so that the placement groove (110) is located at the lower end of the protruding portion (13) of the electrode roll; and a second movement mode, in which the placement portion (100) moves in a second direction (F2) so that the lower end of the protruding portion (13) of the electrode roll is placed on the placement groove (110), and the second direction (F2) is a direction perpendicular to the first direction (F1).

[0059] In addition, in the first movement mode, the packaging bag placement portion (700) can be configured to push the edge portion of the first packaging bag located on the top of the protruding portion (13) toward the support plate (12) while moving along the first direction (F1) from the top side of the protruding portion (13).

[0060] refer to Figure 3 and Figure 4In the first movement mode, the packaging bag placement part (700) can move from the top side of the protruding part (13) along the first direction (F1). The packaging bag placement part (700) can be arranged vertically to face the placement part (100) with the protruding part (13) interposed therebetween. The packaging bag placement part (700) can tightly attach the edge portion of the first packaging bag (20) located around the support plate (12) of the electrode roll to the support plate (12) side from the top side of the protruding part (13) along the first direction (F1).

[0061] In addition, in the first movement mode, the packaging bag placement part (700) may be configured to move spaced apart from the support plate (12) by a predetermined distance (d).

[0062] In the first movement mode, the edge portion (22) of the first packaging bag located around the support plate (12) can be accommodated in the space (S) formed by the gap (d) between the packaging bag arrangement portion (70) and the support plate (12). That is, in the first movement mode, the first packaging bag portion pushed to the support plate (12) side by the packaging bag arrangement portion (700) can be accommodated in the space (S) formed by the gap (d) between the packaging bag arrangement portion (700) and the support plate (12).

[0063] When the seating mode is executed, the control unit (600) may control the second movement mode to be executed after the first movement mode is executed. In the first movement mode, the seating unit (100) and the protruding portion (13) are not in contact with each other, while in the second movement mode, the protruding portion (13) is seated on the seating groove (110).

[0064] In addition, the conveying device (1) for the electrode double packaging device may include: a placement gasket (200), which is arranged in the placement groove (110); a wear sensing sensor (300), which is used to sense the wear of the placement gasket (200); and a notification part (400), which is used to notify the gasket to be replaced when the wear sensing sensor senses the wear of the placement gasket (200).

[0065] The placement pad (200) is arranged in a placement groove (110) in which the protruding portion (13) of the primary packaged electrode roll is placed. Therefore, the placement pad (200) has a placement surface on which the protruding portion (13) of the electrode roll is placed. The wear sensing sensor (300) senses the wear of the placement pad (200). When the wear sensing sensor (300) senses the wear of the placement pad (200), the notification unit (400) notifies the replacement of the pad.

[0066] In addition, the control part (600) can control the operation of the moving part (500) according to whether the wear sensing sensor (300) senses the wear of the placement pad (200).

[0067] The seating gasket (200) may be formed of a material different from that of the seating groove (110). For example, the seating gasket (200) may be a rubber gasket formed of a rubber material.

[0068] The conveying device (1) according to the present application notifies the replacement time of the rubber gasket (200) through the wear sensing sensor (300) and the notification unit (400), thereby preventing the packaging bag from being torn by the worn rubber gasket (200). The wear sensing sensor (300) can be, for example, a laser sensor.

[0069] The wear sensing sensor (300) is configured to recognize a mounting surface of the unworn rubber gasket (200). When the rubber gasket (200) is worn, the wear sensing sensor (300) generates an error because the mounting surface is not recognized. In addition, the wear sensing sensor (300) is configured to recognize at least some areas of the rubber gasket (200). The wear sensing sensor (300) is configured to recognize at least some areas of the rubber gasket (200). Thus, in the process of replacing a worn rubber gasket (200) with a new one, if the new rubber gasket is not installed due to mistake (gasket missing), at least some areas of the rubber gasket (200) are not recognized, thereby generating an error.

[0070] When such an error occurs, the notification part (400) can notify the replacement time of the worn gasket using visual and auditory methods.

[0071] Furthermore, the wear sensing sensor (300) may include a laser sensor.

[0072] Furthermore, when the laser sensor senses wear of the rubber gasket (200), the control portion (600) may be configured to stop executing the placement mode and the conveying mode of the moving portion (500).

[0073] Since the operation of the moving part (500) is controlled by the control part (600), the operator can safely perform the replacement work of the worn pad.

[0074] For example, when the wear sensing sensor (300) senses wear of the rubber gasket (200), the control unit (600) may stop executing the placement mode and the conveying mode of the moving unit (500). In addition, when the placement mode and the conveying mode of the moving unit (500) are stopped, the entire process of the packaging device may be stopped. This is to prevent the product in which the packaging bag is torn by the worn rubber gasket from being shipped out as a final product.
