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 connection position).

[0028] 3a to 3d are diagrams showing a state in which pouch supplying device 1 according to one embodiment of the present invention prepares for transfer of 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.

As a specific example, the adsorption unit 23 may adsorb an 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 pouch 130 may 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 can 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 placement pad 24. The placement pad 24 may be provided so that an end of the pouch 130 is placed on it. For example, the suction unit 23 may adsorb the end of the pouch 130, and the adsorbed end of the pouch 130 may be placed on the placement pad 24. The placement pad 24 may be provided so that the end of the pouch 130 is adsorbed so that the placement is maintained. For example, the placement pad 24 may include a suction pad, and the end of the pouch 130 may be adsorbed using the suction pad. The angle of the placement pad 24 may be adjusted so that the end of the pouch 130 is 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 transport 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 as to have a moving direction parallel to the moving direction of the first rail unit 22. Also, the second rail unit 25 may be installed spaced apart from the first rail unit 22.

The collecting plate 71 may be movable relative to the support section 40. More specifically, the collecting plate 71 may be located on the opposite side of the pouch roll 110 relative to the support section 40, and may move in a direction opposite to the direction in which the transfer section 20 transfers the pouch roll 110 to move close to the support section 40. When the support section 40 releases the support for the collecting core 120-1, the collecting plate 71 may move close to the support section 40. When the collecting core 120-1 is accommodated in the collecting plate 71, the collecting plate 71 may move away from the support section 40.

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

[0045] When the existing pouches 51 are being supplied using an existing pouch roll and the existing pouches 51 are exhausted, the pouch supplying device 1 can disengage the core support member 41 of the support section 40 supporting 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 section 70 by gravity.

[0046] Explaining with reference to FIG. 5a, the pouch supplying 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 at a lower part 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 end 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 unwinding state.

[0047] 5b, the support unit 40 can support the pouch roll 110. For example, when the pouch roll 110 is moved to the connecting 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 connecting 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 according to the movement of the support unit 40.
