Note that the shaft member 2 is made of any material such as paper, resin, rubber, and the like, and any one of a tubular shape and a solid shape can be adopted.

  The rotation drive unit 4 includes a rotation motor 41 as a drive device, and an output shaft 42 of the rotation motor 41 supports the drive roller 3A.

  The pressing means 5 includes a linear motor 51 as a driving device, and the slider 52 of the linear motor 51 supports the pressing roller 3C. The linear motor 51 can detect and control the output torque, and can apply a predetermined clamping force to the wound material RB.

  The detection means 6 is built in the linear motor 51 and is constituted by a position sensor that detects the position of the slider 52. However, as long as it detects the displacement amount of the pressing roller 3C, the detection means 6 is non-contact such as an area sensor or a line sensor. Any configuration such as a type sensor, a contact type sensor such as a limit switch, and an imaging apparatus such as a camera can be employed.

  The moving means 7 is composed of a linear motor 71 as a drive device. The first slider 72 of the linear motor 71 supports the rotation motor 41, and the second slider 73 of the linear motor 71 supports the driven roller 3B. ing.

  The supply / discharge means 8 includes a linear motor 81 as a drive device provided below the linear motor 71, a linear motion motor 83A as a drive device supported by the first slider 82A of the linear motor 81, and an output shaft 84A thereof. Are mounted on a linear motor 85A as a driving device supported by the slider, a pair of sliders 86A, a mounting frame 87A provided to be capable of mounting a roll RB, and a second slider 82B of the linear motor 81. A linear motion motor 83B as a supported drive device, a linear motor 85B as a drive device supported by the output shaft 84B, and a pair of sliders 86B are supported by the pair of sliders 86B so that the wound material RB can be placed thereon. The mounting frame 87B is provided. The mounting frames 87A and 87B are provided so as to be movable in the left-right direction in FIG.

In the support device 1 described above, a procedure for winding the adhesive sheet AS and a procedure for feeding the adhesive sheet AS will be described.
When winding up the adhesive sheet AS, first, as shown by a two-dot chain line in FIG. 1, the shaft member 2 or a roll RB in which a predetermined amount of the adhesive sheet AS is wound around the shaft member 2 is not shown. When placed on the placement frame 87B by the means or the like, the supply / discharge means 8 drives the linear motor 81 and the linear motion motor 83B to move the placement frame 87B so that the shaft member 2 or the wound material RB is shown in FIG. Supply to the winding position indicated by the solid line. When the shaft member 2 and the wound product RB are supported by the mounting frames 87A and 87B, each linear motor 85A is used if the outer diameter of the shaft member 2 or the wound product RB is always constant. 85B, a width corresponding to the outer diameter may be stored as a support width, and the mounting frames 87A and 87B may be moved so as to be the support width. In addition, when the outer diameter of the wound product RB is an unspecified size due to the winding amount of the adhesive sheet AS, the outer diameter of the wound product RB is measured by a detection unit (not shown) such as an optical sensor or an imaging unit. Alternatively, the linear motors 85A and 85B may store the width corresponding to the outer diameter as the support width, and then move the mounting frames 87A and 87B so as to be the support width.

  Next, the moving means 7 drives the linear motor 71 to bring the driving roller 3 </ b> A and the driven roller 3 </ b> B closer to support the shaft member 2 or the wound material RB from below, and the pressing means 5 drives the linear motor 51. Then, the pressing roller 3C is lowered to press the shaft member 2 or the wound material RB against the driving roller 3A and the driven roller 3B. At this time, the moving means 7 is driven by the drive roller 3A and the driven roller 3A so as to have the stored support width corresponding to the outer diameter of the shaft member 2 and the wound material RB in the same manner as the linear motors 85A and 85B. The roller 3B is brought closer. Further, the pressing means 5 controls the driving torque of the linear motor 51 so as to apply a predetermined clamping force to the wound object RB via a detection means (not shown). Further, the moving means 7 positions the driving roller 3A and the driven roller 3B in line symmetry with respect to the center line L1 in the moving direction of the pressing roller 3C, whereby each of the driving roller 3A, the driven roller 3B, and the pressing roller 3C rotates. The shaft member 2 or the wound material RB can be held in a positional relationship in which the straight line connecting the axes is an equilateral triangle or an isosceles triangle. The pressing means 5 applies the adhesive roller AS to the adhesive sheet AS by the driving roller 3A, the driven roller 3B, and the pressing roller 3C in accordance with an increase in the weight or outer diameter of the wound material RB due to the wound adhesive sheet AS. The driving torque of the linear motor 51 can also be controlled so that the clamping force is gradually increased or decreased.

  Next, the supply / discharge unit 8 drives the linear motor 83B and the linear motor 81 to lower the mounting frame 87B, and then moves the mounting frame 87B to the right. Then, the adhesive sheet AS to be wound up is connected to the rear end portion of the adhesive member AS of the shaft member 2 or the roll RB by connecting means (not shown) or manually. Connect.

  Next, the rotation driving means 4 drives the rotation motor 41 to drive the drive roller 3A in the counterclockwise direction in FIG. 1, and to rotate the shaft member 2 or the wound material RB in the clockwise direction in FIG. Then, the adhesive sheet AS is wound up (see FIG. 2). While the adhesive sheet AS is being wound, the pressing means 5 controls the driving force of the linear motor 51 and continues to apply a predetermined clamping force to the wound material RB via the pressing roller 3C. As the diameter of the roll RB increases, it rises. When the pressing roller 3C rises, the detecting means 6 detects the position of the slider 52, and the moving means 7 separates the driving roller 3A and the driven roller 3B based on the detection result of the detecting means 6, and the driving roller 3A and the driven roller 3B. , And the pressing roller 3 </ b> C are separated from each other while maintaining a positional relationship in which the pressing roller 3 </ b> C is an equilateral triangle or an isosceles triangle. The driving force of the linear motor 51 controlled by the pressing means 5 depends on the driving roller 3A, the driven roller 3B, and the pressing force according to the weight increase or outer diameter increase of the wound material RB by the wound adhesive sheet AS. You may control so that the clamping force provided to the wound material RB with the roller 3C may increase or decrease gradually.

  When it is confirmed by a detection means such as a contact sensor or an optical sensor (not shown) or by visual observation that a predetermined amount of the adhesive sheet AS has been wound, the rotation drive means 4 stops driving the rotation motor 41. . Next, the supply / discharge means 8 drives the linear motor 81 and the linear motion motor 83A, and brings the placement frame 87A into contact with the wound object RB from below as indicated by a two-dot chain line in FIG. In this case as well, the linear motor 85A moves each mounting frame 87A so as to have the support width stored so as to match the outer diameter of the roll RB, as described above. In this state, the pressing unit 5 drives the linear motor 51, and the moving unit 7 drives the linear motor 71. The driving roller 3A, the driven roller 3B, and the pressing roller 3C are separated from the wound material RB, and the winding is performed. The recycle RB is supported by the mounting frame 87A. Then, after the supply / discharge means 8 drives the linear motion motor 83A and the linear motor 81 to lower the wound product RB, the wound product RB is moved in the left direction as shown by a solid line in FIG. Thereafter, the wound material RB is transported to a separate process by a transport device (not shown) and the like operation is repeated thereafter.

  On the other hand, when the adhesive sheet AS is fed out, first, as shown by a two-dot chain line in FIG. 2, when the wound material RB is placed on the placement frame 87A by a conveying means or the like not shown, the supply / discharge means 8 is The linear motor 81 and the linear motor 83A are driven to move the mounting frame 87A to supply the wound material RB to the feeding position indicated by the solid line in FIG.

  Next, the moving means 7 drives the linear motor 71 and the pressing means 5 drives the linear motor 51 in the same manner as described above, and the roll RB is predetermined by the driving roller 3A, the driven roller 3B, and the pressing roller 3C. Hold with the clamping force of. Next, the supply / discharge means 8 drives the linear motion motor 83A and the linear motor 81 to lower the placement frame 87A, and then moves the placement frame 87A to the left. Then, the adhesive sheet AS to be fed out is connected or hung to a sheet sticking device, a printing device or the like by a driving device (not shown) or manually.

  Next, the rotation driving means 4 drives the rotation motor 41, the drive roller 3A is rotated in the clockwise direction in FIG. 1, and the wound material RB is rotated in the counterclockwise direction in FIG. To pay out. While the adhesive sheet AS is being fed, the pressing means 5 controls the driving force of the linear motor 51 and continues to apply a predetermined clamping force to the wound material RB via the pressing roller 3C. It descends as the diameter of the roll RB decreases. When the pressing roller 3C is lowered, the driving roller 3A, the driven roller 3B, and the pressing roller 3C approach each other while maintaining the positional relationship of being an equilateral triangle or an isosceles triangle in the same manner as described above. In addition, the pressing means 5 is clamped to be applied to the adhesive sheet AS by the driving roller 3A, the driven roller 3B, and the pressing roller 3C in accordance with the weight reduction or outer diameter reduction of the wound material RB by the fed adhesive sheet AS. The driving torque of the linear motor 51 may be controlled so that the force is gradually increased or decreased.

  Then, when it is confirmed by the detection means such as a contact type sensor or an optical sensor (not shown) or visual observation that the adhesive sheet AS has been fed out by a predetermined amount, the rotation drive means 4 stops driving the rotation motor 41. . Next, in the state where the supply / discharge means 8 drives the linear motor 81 and the linear motion motor 83B and the mounting frame 87B is brought into contact with the shaft member 2 or the wound material RB from below, the driving roller 3A, The driven roller 3B and the pressing roller 3C are separated from the shaft member 2 or the wound material RB, and the shaft member 2 or the wound material RB is supported by the mounting frame 87B. Then, the supply / discharge means 8 drives the linear motion motor 83B and the linear motor 81 to lower the shaft member 2 or the wound object RB as shown by a two-dot chain line in FIG. In this way, the shaft member 2 or the roll RB is moved in the right direction. Thereafter, the shaft member 2 or the wound material RB is transported to another process by a transport device (not shown) and the like operation is repeated thereafter.

  According to the present embodiment as described above, since the wound material RB is sandwiched between the driving roller 3A, the driven roller 3B, and the pressing roller 3C, the adhesive sheet AS body can be stably supported. Further, since the shaft member 2 is pressed against the driving roller 3A and the driven roller 3B by the pressing roller 3C, it is possible to prevent the rotationally driven driving roller 3A from rotating idle. Therefore, the adhesive sheet AS can be reliably wound up and fed out.
