Transferring apparatus for material for electrode

1 . A transfer apparatus for a material for an electrode, the transfer apparatus comprising:

an apparatus body;

a gripping device configured to grip a reel wound around a current collector which includes an uncoated region;

a first moving device connected to the gripping device and the apparatus body and configured to move the gripping device;

a position changing device configured to rotate the reel when the reel is seated on the position changing device;

a first discharge device disposed on one side of the apparatus body and configured to move a rotated reel to the outside of the apparatus body when the rotated reel is seated on the first discharge device; and

a second discharge device disposed on the apparatus body and configured to move an unrotated reel to the outside of the apparatus body when the unrotated reel is seated on the second discharge device,

wherein the position changing device rotates the reel to change a position of the uncoated region.

2 . The transfer apparatus of claim 1 , wherein

the reel includes a first reel gripped in a first position and a second reel gripped in a second position, and

the gripping device is configured to seat the first reel on the position changing device and is configured to seat the second reel on the second discharge device.

3 . The transfer apparatus of claim 2 , wherein the position changing device receives the first reel with a first side of the first reel facing the gripping device and rotates the first reel on the first plane so that a second side of the first reel faces the gripping device.

4 . The transfer apparatus of claim 3 , wherein

the first position is a position corresponding to a first outlet of a first slitter, and

the second position is a position corresponding to a second outlet of a second slitter.

5 . The transfer apparatus of claim 4 , wherein

the first discharge device includes a first conveyor device receiving the first reel and moving the first reel along a first path, and

the second discharge device includes a second conveyor device receiving the second reel and moving the second reel along a second path.

6 . The transfer apparatus of claim 1 , wherein

the gripping device includes

a gripping body connected to the first moving device; and

a gripping shaft connected to the gripping body and onto which the reel is deposited.

7 . The transfer apparatus of claim 6 , wherein the first moving device includes

a first gripping moving device configured to move the gripping body in a first direction relative to the apparatus body;

a second gripping moving device configured to move the gripping body in a second direction relative to the apparatus body; and

a third gripping moving device configured to move the gripping body in a third direction relative to the apparatus body.

8 . The transfer apparatus of claim 7 , wherein each of the first gripping moving device, the second gripping moving device, and the third gripping moving device includes

a ball screw installed on the apparatus body or the gripping body;

a motor member rotating the ball screw; and

a transfer nut connected to the ball screw and the gripping body.

9 . The transfer apparatus of claim 1 , wherein each of the first discharge device and the second discharge device includes

a discharge body disposed in the apparatus body;

a discharge shaft connected to the discharge body and on which the reel discharged from the gripping device is seated; and

a finger device configured to move the reel from the gripping device to the discharge shaft when the gripping device and the discharge shaft face each other.

10 . The transfer apparatus of claim 9 , wherein the first discharge device and the second discharge device further include

a discharge frame disposed to face the discharge body, and

the finger device includes

a finger frame connected to the discharge frame so as to be moved relative to the discharge frame; and

at least one finger member connected to the finger frame so as to be moved relative to the finger frame, holding the reel present in the gripping device, and moving the reel to the discharge shaft.

11 . The transfer apparatus of claim 1 , wherein the position changing device includes

a position changing plate on which the reel is seated; and

a position changing moving device connected to the position changing plate and configured to rotate the position changing plate on the first plane, and

the position changing plate includes an inclined region in a surface on which the reel is seated.

12 . The transfer apparatus of claim 11 , wherein the inclined region includes

a first inclined region contacting an outer circumferential surface of the reel and inclined in a first direction; and

a second inclined region contacting the outer circumferential surface of the reel and inclined in a second direction.

13 . The transfer apparatus of claim 1 , wherein the reel includes a first reel aligned having the uncoated region facing a first direction, and a second reel having the uncoated region facing a second direction opposite to the first direction, and

wherein the first reel is moved to the outside of the apparatus body by the first discharge device, and the second reel is moved to the outside of the apparatus body by the second discharge device.
