5 is a perspective view of the recoiler of FIG. 3 ;

The recoiler 150 is a device for rewinding the strips S2 divided by the slitter 130 on the bobbins 152 , and as shown in FIG. 5 , a rotation shaft 151 and a rotation shaft 151 . In the bobbins 152 installed on the, spacers 153 installed on the rotation shaft 151, movement limiting plates 154 for restricting movement of the bobbins 152 and the spacers 153, and the bobbins 152 It consists of an alignment means 155 for aligning the wound strip rolls (R2).

The rotating shaft 151 is rotated by a driving device (not shown), and since a plurality of bobbins 152, spacers 153, and movement limiting plates 154 are installed, the rotating shaft 151 is rotated by the driving device. When done, the bobbins 152 installed on the rotation shaft 151, the spacers 153, and the movement limiting plates 154 are rotated together.

In addition, an electromagnet (not shown) is built in the rotation shaft 151 so as to be coupled with the suction plates 1522 of the bobbin 152 to be described later by magnetic force.

This foremost shaft 151 is configured to be coupled with the bobbins 152 by magnetic force without using a separate fastening means such as bolts, so that only when the rotation shaft 151 rotates, the bobbins 152 and the rotation shaft 151 are Combined by the magnetic force of the electromagnet and rotated together, when the strip roll R2 is finished winding, the power supplied to the electromagnet is cut off so that the coupling by the magnetic force between the rotating shaft 151 and the bobbin 152 is removed. By being configured, the time taken in the process of coupling and separating the rotating shaft 151 and the bobbin 152 can be reduced.

The movement limiting plates 154 are formed in a hollow disk shape and are movably installed on the rotation shaft 151 . In addition, the movement limiting plates 154 are configured to be able to fix their positions on the rotation shaft 151 by the fixing means 1541 .

These movement limiting plates 154 are respectively fixedly installed at positions adjacent to both ends of the rotation shaft 151 to limit the movement of the bobbins 152 and the spacers 153 .

The bobbins 152 are installed on the rotating shaft 151 and configured to be coupled to and separated from the rotating shaft 151 by an electromagnet, and one of the strips S2 divided by the slitter 130 is wound and a strip roll ( R2) is wound.

At this time, when the winding of the strip S2 is completed and the strip roll R2 is formed, the bobbins 152 can be separated by the rotation shaft 151 in a state in which the strip roll R2 is wound.

Since the bobbins 152 configured as described above are configured to be able to separate the strip roll R2 from the bobbin 152 in a state separated by the rotation shaft 151 when the winding operation is completed, the strip roll R2 is separated. It is possible to prevent the strip roll R2 from being deformed or damaged due to contact with other bobbins during the process, as well as to reduce the time taken in the separation process.

6 is an exemplary view of a bobbin on which a strip roll is wound.

As shown in FIG. 6 , the bobbin 152 includes a body 1521 and a suction plate 1522 coupled to one surface of the body 1521 .

The body 1521 is formed in a hollow disk shape, and is installed on the rotation shaft 151 .

At this time, on the outer peripheral surface of the main body 1521, the locking protrusions 15211 are formed at intervals along a circular arc.

The main body 1521 rotates with the central tube P when the locking protrusions 15211 are inserted into the insertion grooves formed on the inner circumferential surface of the central tube (P).

At this time, the central pipe (P) is formed in a tubular shape, the strip (S2) is wound, it is a place where the strip roll (R2) is formed.

In addition, the inner circumferential surface of the central tube (P) is formed inwardly, the insertion grooves extending to the front and rear surfaces are formed at intervals along a circular arc.

This central pipe (P) is arranged in the center of the strip roll (R2) to prevent the strip (S2) at the hollow position of the strip roll (R2) formed in the shape of a hollow disk from being released, as well as from the outside It prevents the shape of the strip roll R2 from being deformed by vibration or impact.

The body 1521 configured in this way is configured such that the locking protrusions 15211 are inserted into the insertion groove formed on the inner circumferential surface of the central pipe P and rotated together with the central pipe P, so that the inner diameter of the central pipe P or the body ( Due to the error of the outer diameter of 1521), a space is formed between the central pipe P and the main body 1521, so that it is possible to prevent the central pipe P from spinning when the main body 1521 is rotated.

Through this, in the main body 1521, the central pipe (P) is idle and the rotational speed of the central pipe (P) is irregularly changed, so that the strip (S2) is wound around the central pipe (P) at an irregular speed. ), it is possible to prevent the formation of a space between the strip rolls (R2) from being formed in an elliptical shape rather than a circular shape due to torsion, wrinkling, etc. It can be prevented from being damaged in the process.

In addition, since the central tube P is coupled to the outside of the main body 1521 by the locking protrusion 15211, the strip roll R2 is formed to separate the bobbin 152 from the rotation shaft 151, the main body ( 1521), the central pipe (P) and the strip roll (R2) are separated from the rotation shaft 151 in a coupled state.

The suction plates 1522 are installed on one side of the body 1521 at intervals along the circumferential direction.

At this time, the suction plates 1522 are formed of an arc-shaped plate, and made of a metal material through which electricity is passed. In addition, when the bobbin 152 is installed on the rotating shaft 151 , the suction plates 1522 are installed at a position where the inner circumferential surface is in contact with the outer circumferential surface of the rotating shaft 151 .

Since these suction plates 1522 are coupled to the rotation shaft 151 by the magnetic force of the electromagnet installed inside the rotation shaft 151, the electromagnet is operated only when the winding operation of the strip S2 is in progress, and the rotation shaft 151 and the bobbin 152. They are coupled by magnetic force, and when the winding operation is completed, the operation of the electromagnet is stopped so that the bobbins 152 can be easily separated from the rotation shaft 151 .

The bobbin 152 configured in this way is configured such that the central pipe P is coupled to the outside of the main body 1521, and the strip S2 is wound around the central pipe P. When the winding of the strip S2 is completed, Since the bobbin 152, the center tube P, and the strip roll R2 are integrally coupled, when the bobbin 152 is separated from the rotation shaft 151, the center tube P and the strip roll R2 are separated from the bobbin ( 152) and separated together.

The bobbin 152 separates the center tube P and the strip roll R2 from the bobbin 152 because the bobbin 152 can be separated by the rotation shaft 151 when the center tube P and the strip roll R2 are separated. It is possible to prevent the strip roll R2 from being damaged by contacting the strip roll R2 with other bobbins or spacers 153 and movement limiting plates 154 during the process.

The spacers 153 are formed in a hollow disk shape, and are movably installed on the rotation shaft 151 in the longitudinal direction of the rotation shaft 151 . In this case, the movement range of the spacers 153 is limited by the movement limiting plates 154 .

In addition, the spacers 153 may have various thicknesses, and may be installed between the bobbins 152 to adjust the distance between the bobbins 152 .

Since these spacers 152 are installed between the movement limiting plates 154 and occupy space, they are installed between the bobbins 152 to adjust the distance between the bobbins 152 as well as the bobbins 152 . And by being installed between the movement limiting plates 154 and configured to occupy space, the bobbins 152 limit the axial movement of the rotating shaft 151 to determine the final installation positions of the bobbins 152 .

The aligning means 155 is composed of a long cylindrical body 1551 and a hollow disk-shaped dividing plate 1552 installed on the outer circumferential surface of the body 1551 .

At this time, the alignment means 155 is installed so that the body 1551 is installed at a position parallel to the rotation shaft 151 and spaced apart from the rotation shaft 151 so that the dividing plates 1552 are disposed directly above the space formed between the bobbins 152 .

In addition, the alignment means 155 is configured to prevent direct contact with the strip roll R2 when the strip S2 is wound around the bobbins 152 to increase the size of the strip roll R2. ) is installed to be movable in a direction away from

The aligning means 155 separates the strip rolls R2 that are wound on each of the bobbins 152 by inserting the dividing plates 1552 between the strip rolls R2 during the winding operation of the strip S2, The strip roll R2 is moved in a direction spaced apart from the strip roll R2 in the process of being wound, thereby preventing the outer peripheral surface of the aligning means 155 from coming into direct contact with the strip roll R2.

The recoiler system 100 configured in this way releases the roll R1 manufactured with a wide width into the sheet S1 through the decoiler 110 , and the sheet S1 is released into a plurality of sheets by the slitter 130 . By being divided into strips S2 and configured to form a plurality of strip rolls R2 through the recoiler 150, the wide sheet S1 can be divided into an appropriate width for work.

In addition, since the recoiler system 100 is configured such that the bobbins 152 and the central tube P are coupled to each other by the locking protrusions 15211 protruding from the outer circumferential surface of the bobbin 152, the bobbin 152 and the central tube ( P) is configured to rotate integrally, so that it is possible to prevent the strip (S2) from being abnormally wound due to the central tube (P) spinning in vain. Since (P) and the strip roll (R2) are separated in a state coupled to the bobbin (152) to separate the center tube (P) and the strip roll (R2), the center tube (P) and the strip roll (R2) are separated. It is possible to prevent the strip roll R2 from being damaged by contact with the other strip roll R2 during the separation process.

In addition, since the roller 25534 is installed between the bottom surface of the roller insertion groove 25212 and the engaging projection 25213, the longitudinal movement of the rotation shaft 251 is limited.

When the second bobbin 252 is rotated, the roller 25534 is rotated at a fixed position because it is in rotational contact with the outer circumferential surface of the roller insertion groove 25212 .

In addition, when the connecting portion 2553 is moved in a direction spaced apart from the second bobbin 252 as the size of the strip roll R2 formed on the second bobbin 252 is increased, the movable bar 25532 is guided by the moved distance. It protrudes from the block 25531 and remains disposed between the bobbins 252 .

The second aligning means 255 configured in this way has the connecting portions 2553 disposed between each bobbin 252, and the strip rolls R2 wound on the bobbins 252 are guided by a guide block 25531 and a movable bar ( 25532), it is possible to prevent the strip rolls R2 from being deformed by being pressed by external vibration or impact, as well as the distance between the second bobbin 252 and the second aligning means 255 It is configured to be divided between the strip rolls R2 by the guide block 25531 and the movable rod 25532 even if the is spaced apart.
