[0015] FIG. 1 shows a pouch supplying device 1 according to one embodiment of the present invention.

[0016] The pouch supplying device 1 may be a device that is provided to supply sheet-like pouches to a subsequent process.

[0017] The pouch supply device 1 may include a supply unit 10. For example, the supply unit 10 may receive a pouch roll 110 from an external source. The pouch roll 110 may have sheet-like pouches 130 wound around a core 120. The core 120 may be cylindrical and hollow, but is not limited thereto. Within the pouch supply device 1, the supply unit 10 may supply the pouch roll 110 to a transfer unit 20.

[0018] The pouch supply device 1 may include a transfer unit 20. The transfer unit 20 may transfer the pouch roll 110. For example, the transfer unit 20 may support the pouch roll 110 and transfer the pouch roll 110. The transfer unit 20 may be formed to extend along a transfer path of the pouch roll 110 (e.g., a path from a supply position to a connection position). The supply position may be a position where a supply unit 10 that receives a supply of the pouch roll 110 is installed, and the connection position may be a previously set position where a support unit 40, which will be described later, is installed.

[0019] The pouch supply device 1 may include a sub-support unit 30. The sub-support unit 30 may rotatably support the pouch roll 110. For example, the sub-support unit 30 may be provided to rotatably support the pouch roll 110 at a standby position located forward of the connecting position. As a specific example, the sub-support unit 30 may include a core support member 31 that is inserted into the core 120 of the pouch roll 110 to rotatably support the pouch roll 110. The core support member 31 may be formed on the sub-support unit 30 so as to be insertable into the core 120. The sub-support unit 30 may rotatably support the pouch roll 110 by inserting the core support member 31 into the core 120, and may release support for the pouch roll 110 by removing the core support member 31 from the core 120. The standby position is a position where the sub-support unit 30 is installed, and may be a position between the supply position and the connecting position.

[0020] The pouch supply device 1 may include a support unit 40. For example, the support unit 40 may be provided to rotatably support the pouch roll 110 at a connection position where the pouches 130 are connected to the existing pouches 51. As a specific example, the support unit 40 may include a core support member 41 that is inserted into the core 120 of the pouch roll 110 and rotatably supports the pouch roll 110. The core support member 41 may be formed in a sub-support unit 40 that is insertable into the core 120. The sub-support unit 40 may rotatably support the pouch roll 110 by inserting the core support member 41 into the core 120, and may release support for the pouch roll 110 by removing the core support member 41 from the core 120.

[0021] The pouch supply device 1 may include a placing unit 50. The placing unit 50 may supply sheet-like pouches to a subsequent process. For example, the placing unit 50 may include a plurality of rollers, and the pouches placed on the rollers may be supplied to a subsequent process by rotating the rollers. As another example, after existing pouches 51 are placed on the placing unit 50 and supplied to a subsequent process, pouches 130 may be connected to the placing unit 50 before the existing pouches 51 are consumed. The placing unit 50 may supply the connected existing pouches 51 and pouches 130 to a subsequent process. For example, the existing pouches 51 and pouches 130 placed on the rollers may be supplied to a subsequent process by rotating the rollers. However, the method by which the placing unit 50 supplies pouches to a subsequent process is not limited to the above.

[0022] The pouch supply device 1 may include a connecting unit 60. The connecting unit 60 may be provided to connect an existing pouch 51 to a pouch 130. For example, the connecting unit 60 can connect an existing pouch 51 placed on the placing unit 50 to a pouch 130 of the pouch roll 110 supported by the supporting unit 40.

[0023] The pouch supply device 1 may include a core recovery unit 70. The core recovery unit 70 may be configured to recover the cores 120. For example, when the pouches 130 are exhausted, the core recovery unit 70 can recover the cores 120 when the support unit 40 releases the support of the pouch roll 110 from the cores 120. The core recovery unit 70 can move toward or away from the support unit 40.

[0024] FIG. 2 shows a supply section 10 and a transfer section 20 in a pouch supply device 1 according to one embodiment of the present invention.

[0025] The supply unit 10 may be provided to receive the pouch roll 110. For example, the supply unit 10 may include a supply standby unit 11. The supply standby unit 11 may support both ends of the pouch roll 110 at a predetermined distance. Both ends of the pouch roll 110, on which pouches 130 are wound around a core 120, may be placed on the supply standby unit 11.

[0026] The transfer unit 20 may include a roll support unit 21. For example, the roll support unit 21 may be installed at a position corresponding to the supply standby unit 11. When the pouch roll 110 is supplied and placed on the supply unit 10, the roll support unit 21 may support the pouch roll 110 from below together with the supply standby unit 11. When the pouch roll 110 is transferred, the roll support unit 21 may support the pouch roll 110 from below and transfer the pouch roll 110.

[0027] The transfer unit 20 may include a first rail unit 22. For example, the first rail unit 22 may be formed to connect a position where the supply unit 10 is installed (e.g., a supply position) to a position where the support unit 40 is installed (e.g., a coupling position). The roll support unit 21 may be coupled to the first rail unit 22 so as to be able to move between the supply unit 10 and the support unit 40 (or between the supply position and the coupling position).

[0028] 3a to 3d are diagrams showing the pouch supplying device 1 according to one embodiment of the present invention, preparing to transfer the pouch roll 110. FIG.

[0029] 3a, the transfer unit 20 can transfer the pouch roll 110 from a supply position to a standby position (or a position where the sub-support unit 30 is installed). For example, when the placement unit 50 is supplying existing pouches 51 of an existing pouch roll to a subsequent process, the transfer unit 20 can transfer the pouch roll 110 to a standby position where the sub-support unit 30 is installed. As a specific example, the pouch roll 110 can be moved by the roll support unit 21 to the position where the sub-support unit 30 is installed (or the standby position).

[0030] The sub-support unit 30 can support the pouch roll 110. For example, the sub-support unit 30 can support the pouch roll 110 by inserting a core support member 31 into the core 120. The sub-support unit 30 can also rotate the pouch roll 110 by rotating the core support member 31. More specifically, the sub-support unit 30 can be configured to be movable in the axial direction of the pouch roll 110, and the core support member 31 can be inserted into or removed from the core 120 in response to the movement of the sub-support unit 30.

[0031] 3b, a restraining member 140 may be coupled to the pouch roll 110. For example, the restraining member 140 may be attached to the pouch roll 110 to prevent the sheet-like pouches 130 wound around the core 120 from loosening. The restraining member 140 may be attached to the pouch roll 110 so as to restrain the ends of the pouches 130. For example, the restraining member 140 may be a tape attached to the ends of the pouches 130.

[0032] The pouch supply apparatus 1 may include a peeling device 80. The peeling device 80 may be configured to remove the binding member 140. For example, the peeling device 80 may include a peeling gripper 81. The peeling device 80 can use the peeling gripper 81 to grip the binding member 140 attached to the pouch roll 110 and peel and remove the binding member 140.

[0033] The peeling device 80 may be installed near the position (or standby position) where the sub-support unit 30 is installed. For example, the peeling device 80 may remove the restraining member 140 coupled to the pouch roll 110 while the pouch roll 110 is supported by the sub-support unit 30 at the standby position. In this case, the sub-support unit 30 may rotate the core support member 31 so that the restraining member 140 attached to the pouch roll 110 is positioned corresponding to the position of the peeling gripper 81. However, the present invention is not limited to this.

[0034] 3c and 3d, the pouch supply device 1 may include a suction unit 23. The suction unit 23 can partially unwind the pouches 130 from the core 120. For example, the suction unit 23 can suction the pouches 130 of the pouch roll 110 and partially unwind the pouches 130 from the core 120. As a specific example, the suction unit 23 can suction the end of the pouch 130 of the pouch roll 110 from which the restraining member 140 has been removed and move (e.g., move upward), and the pouches 130 can be partially unwinded from the core 120.

[0035] The suction unit 23 can suction the pouch 130 within a predetermined time range based on the time when the peeling device 80 removes the restraining member 140. For example, the suction unit 23 may suction the pouch 130 before the peeling device 80 removes the restraining member 140. As another example, the suction unit 23 can suction the pouch 130 after the peeling device 80 removes the restraining member 140. As yet another example, the suction unit 23 can suction the pouch 130 at the same time when the peeling device 80 removes the restraining member 140.

[0036] The transfer unit 20 may include a mounting pad 24. The mounting pad 24 may be provided so that an end of the pouch 130 can be placed on it. For example, the suction unit 23 can suction the end of the pouch 130, and the suctioned end of the pouch 130 can be placed on the mounting pad 24. The mounting pad 24 may be provided so that the end of the pouch 130 can be suctioned to maintain the placement. For example, the mounting pad 24 may include a suction pad, and the end of the pouch 130 can be suctioned using the suction pad. The angle of the mounting pad 24 may be adjusted so that the end of the pouch 130 can be easily placed on it.

[0037] FIG. 4 is a diagram showing the transfer of pouch roll 110 in pouch supplying device 1 according to one embodiment of the present invention.

[0038] The transfer unit 20 may include a second rail unit 25. For example, the second rail unit 25 may be formed to extend from a standby position (or a position where the sub-support unit 30 is installed) to a connection position (or a position where the support unit 40 is installed). As another example, the second rail unit 25 may be installed alongside the first rail unit 22 so that the movement direction of the second rail unit 25 is parallel to the movement direction of the first rail unit 22. Alternatively, the second rail unit 25 may be installed spaced apart from the first rail unit 22.

[0039] The mounting pad 24 may be coupled to the second rail portion 25. For example, the mounting pad 24 may be coupled to the second rail portion 25 so as to be movable along the second rail portion 25.

[0040] The transfer unit 20 can transfer the pouch roll 110 to a position where the support unit 40 is installed (or a connecting position). The transfer unit 20 can transfer the pouch roll 110 to the connecting position using the roll support unit 21 and the first rail unit 22. For example, the roll support unit 21 can support the pouch roll 110 at a lower portion and transfer the pouch roll 110 to the connecting position along the first rail unit 22. The placement pad 24 can transfer the pouch roll 110 to the connecting position along the second rail unit 25 while adsorbing the ends of the pouches 130 of the pouch roll 110. The pouch roll 110 can be supported and adsorbed by the roll support unit 21 and the placement pad 24 and transferred to the connecting position. In this case, the pouch roll 110 can be transferred to the connecting position in a partially unwind state.

[0041] 5a and 5b are diagrams showing preparation for connection of pouch rolls 110 in pouch supplying device 1 according to one embodiment of the present invention.

[0042] The pouch supply device 1 can include a core collection section 70 .

[0043] The core recovery unit 70 may include a recovery plate 71. For example, the recovery plate 71 may be formed with a step or a slope so that the cores 120 can roll. The recovery plate 71 may also be movable relative to the support unit 40. More specifically, the recovery plate 71 may be located on the opposite side of the pouch roll 110 from the support unit 40, and may move in a direction opposite to the direction in which the transfer unit 20 transfers the pouch roll 110, thereby moving closer to the support unit 40. When the support unit 40 releases its support for the recovery core 120-1, the recovery plate 71 may move closer to the support unit 40. When the recovery core 120-1 is accommodated in the recovery plate 71, the recovery plate 71 may move away from the support unit 40.

[0044] The core collection unit 70 may include a collection barrel (not shown). The collection barrel may be installed at a distance from the support unit 40 and may move closer to the collection barrel when the collection plate 71 moves away from the support unit 40. When the collection plate 71 moves closer to the collection barrel, the collection core 120-1 may roll and be received in the collection barrel.

[0045] When the existing pouches 51 are being supplied using an existing pouch roll and the existing pouches 51 are exhausted, the pouch supply device 1 can disengage the core support member 41 of the support unit 40 that supports the existing pouch roll from the core 120-1. With the core support member 41 disengaged, the recovery core 120-1 can fall into the core recovery unit 70 by gravity.

[0046] Referring to FIG. 5a, the pouch supply device 1 can use the transfer unit 20 to transfer the pouch roll 110 to a position where the support unit 40 is installed (or a connecting position). For example, the transfer unit 20 can transfer the pouch roll 110 to the connecting position using the roll support unit 21 and the first rail unit 22. As a specific example, the roll support unit 21 supports the pouch roll 110 from below and can transfer the pouch roll 110 to the connecting position along the first rail unit 22. The placement pad 24 can transfer the pouch roll 110 to the connecting position along the second rail unit 25 while adsorbing the ends of the pouches 130 of the pouch roll 110. The pouch roll 110 can be transferred to the connecting position while being supported and adsorbed by the roll support unit 21 and the placement pad 24. In this case, the pouch roll 110 can be transferred to the connecting position in a partially unwound state.

[0047] 5b, the support unit 40 can support the pouch roll 110. For example, when the pouch roll 110 is moved to the connection position, the support unit 40 can insert the core support member 41 into the core 120 of the pouch roll 110. The support unit 40 can rotatably support the pouch roll 110 at the connection position by inserting the core support member 41 into the core 120. More specifically, the support unit 40 can be configured to be movable in parallel with the axial direction of the pouch roll 110, and the core support member 41 can be inserted into or removed from the core 120 depending on the movement of the support unit 40.

[0048] 6a to 6b and 7a to 7b are diagrams showing connections of pouch rolls 110 in a pouch supplying device 1 according to one embodiment of the present invention.

[0049] 6a, the angle of the mounting pad 24 may be adjusted so that the end of the pouch 130 faces up or down. For example, the angle of the mounting pad 24 may be adjusted so that the end of the pouch 130 faces up or down so that the gripper 61 can easily grip a portion of the pouch 130.

[0050] 6b, the connecting unit 60 may include a gripper 61. The gripper 61 may be provided to be movable while gripping the pouch 130. For example, the gripper 61 may be coupled to a separate rail unit so as to be movable in the vertical direction relative to the support unit 40. The gripper 61 may grip a portion of the pouch 130 and move the portion of the pouch 130 to a position corresponding to the end of the existing pouch 51.

[0051] The connecting unit 60 may include a connecting working unit 62. The connecting working unit 62 may connect the pouch 130 to the existing pouch 51. For example, the connecting working unit 62 may be configured to perform crimping, cutting, or taping on the existing pouch 51 and pouch 130.

[0052] Explained with reference to FIGS. 7a and 7b, the connecting working unit 62 can crimp the existing pouch 51 and pouch 130 together.

[0053] The gripper 61 can grip a portion of the pouch 130 and move the portion of the pouch 130 to a position corresponding to the end of the existing pouch 51. Alternatively, the gripper 61 can grip a portion of the pouch 130 and move the portion of the pouch 130 between a first crimping portion 63 and a second crimping portion 64, which will be described later.

[0054] The connecting working unit 62 may include a first crimping unit 63 and a second crimping unit 64. For example, the first crimping unit 63 and the second crimping unit 64 may be disposed at positions corresponding to (or facing) each other.

[0055] Furthermore, the first crimping portion 63 and the second crimping portion 64 may be installed at positions corresponding to the ends of the existing pouch 51. For example, the ends of the existing pouch 51 may be in a state of hanging down below the placing portion 50. The first crimping portion 63 may be installed to be located below the placing portion 50 and to face the ends of the existing pouch 51 that hang down. In this case, the second crimping portion 64 may be installed to face the first crimping portion 63 with the end of the existing pouch 51 sandwiched therebetween.

[0056] The edge of the existing pouch 51 may be cut by a cutting unit 65, which will be described later, and the cutting unit 65, which will be described later, may be installed at a position corresponding to the position of the second crimping unit 64. The connecting work unit 62 can crimp the existing pouch 51 and the pouch 130 together using the first crimping unit 63 and the second crimping unit 64.

[0057] 8a to 8c are diagrams showing cutting of pouch rolls 110 during connection in pouch supplying device 1 according to one embodiment of the present invention.

The cutting unit 65 may perform cutting on the pouch 130 while the gripper 61 is gripping a portion (e.g., an end) of the pouch 130. For example, the cutting unit 65 may perform cutting on a portion (or end) of the pouch 130 while the existing pouch 51 and the pouch 130 are crimped together via the first crimping unit 63 and the second crimping unit 64. In this case, the second crimping unit 64 may include an area formed so that a blade can penetrate along the cutting path of the cutting unit 65. Alternatively, a height difference may be formed between the second crimping unit 64 and the first crimping unit 63, and the cutting unit 65 may be used to cut a portion (or end) of the pouch 130 through a space formed by the height difference. Alternatively, in a state where the existing pouch 51 and pouch 130 are attached (or temporarily attached) via the first crimping unit 63 and the second crimping unit 64, the position of the second crimping unit 64 may be moved and the cutting unit 65 may move close to the pouch 130 to perform cutting. The above description of the first crimping unit 63 and the second crimping unit 64 is merely an example and is not limited to the above.

[0059] The connecting work unit 62 may include a cut pouch processing unit 67. The cut pouch processing unit 67 may be provided to process the cut and separated portion of the pouch 130. For example, when the cutting unit 65 cuts a portion of the pouch 130, the pouch 130 may be divided into a portion gripped by the gripper 61 and a remaining portion (e.g., a portion extending from the portion crimped with the existing pouch 51 to the pouch roll 110). The cut pouch processing unit 67 may suck the portion gripped by the gripper 61 (e.g., an end of the pouch 130 or the cut pouch 67-1) and move it to another location for processing.

[0060] 9a to 9c are diagrams showing taping of a pouch roll 110 in a pouch supplying device 1 according to one embodiment of the present invention.

[0061] 9a to 9c, the connecting work unit 62 may include a taping unit 66. The taping unit 66 may perform taping along the cutting path along which the cutting unit 65 cuts the pouch 130. For example, when the cutting unit 65 cuts a portion of the pouch 130, the pouch 130 may be divided into a cut pouch 67-1 (or the portion gripped by the gripper 61) and the remaining portion (e.g., the portion extending from the portion crimped to the existing pouch 51 to the pouch roll 110). The taping unit 66 may perform taping using a connecting tape 66-1 to cover the remaining portion of the pouch 130, a portion of the existing pouch 51, and the cutting path. When the taping unit 66 performs taping, the existing pouch 51 and the pouch 130 may be connected.

[0062] The taping unit 66 may be installed at a position corresponding to the second crimping unit 64.
