−Configuration−
First, the configuration of the take-out device 100 according to the present embodiment will be described with reference to FIGS. 1 and 4. The take-out device 100 is configured to take out a roll 170 (roll completed with rewinding) that has been wound up by a rewinding device (not shown).

  Here, the rewinding device feeds the belt-shaped sheet from the original fabric and continuously cuts the sheet along the conveying direction to divide the sheet into a plurality of sheets having a smaller width than the original fabric. Each of the divided sheets is wound around the core 160. Specifically, in the rewinding device, a plurality of cores 160 are attached to a long winding shaft 150, and by rotating the winding shaft 150, the divided sheets are transferred to the respective cores 160. By winding, the rolled-up roll 170 is produced.

  The take-out device 100 takes out the rolled up roll 170 together with the take-up shaft 150 from the rewinding device, and also takes out the roll 170 from the take-up shaft 150 and places a new core 160a (see FIG. 6) on the take-up shaft 150. It is configured to be fitted and returned to the rewinding device. Specifically, the take-out device 100 receives the roll 170 that has been wound up from the roll discharge path 51 of the rewinding device, discharges the roll 170, and inserts a new core 160a into the take-up shaft 150 for rewinding. It is configured to return to the take-up shaft supply path 52 of the apparatus. The roll discharge path 51 is disposed above the take-up shaft supply path 52.

  As shown in FIG. 1, the take-out device 100 includes a mounting table 1 on which a roll 170 is mounted, a slide mechanism 2 that slides the mounting table 1, a holding member 3 that holds a winding shaft 150, and a holding device And a support member 4 that supports a winding shaft 150 held by the member 3.

  The mounting table 1 is configured such that the rolled up roll 170 is placed and a new core 160a is placed after the roll 170 is discharged. The mounting table 1 is provided so as to be movable in the vertical direction (Z1 and Z2 directions).

  Further, the mounting table 1 is provided with a support plate 11 that supports the end face of the rolled up roll 170 and a pressing member 12 that presses the new core 160a. The support plates 11 are arranged at both ends in the axial direction (X1 and X2 directions), respectively, and are configured to be movable in the axial direction by a shaftless air cylinder 11a. The pressing member 12 is rotatably provided on the mounting table 1 and can be retracted from the surface of the mounting table 1.

  The slide mechanism 2 is provided to move the mounting table 1 in the axial direction. Specifically, as shown in FIG. 4, the slide mechanism 2 includes a mounting table between a receiving position P2 where the mounting table 1 receives the roll 170 and a discharge position P3 where the roll 170 is discharged from the mounting table 1. 1 is configured to move.

  The holding member 3 includes an upper arm 31 and a lower arm 32 that are rotatably provided. The upper member 31 and the lower arm 32 sandwich the end of the winding shaft 150. The holding member 3 is provided on the side frame 50. That is, the holding member 3 is disposed on the far side (X2 direction side) with respect to the discharge position P3 at the receiving position P2.

  The support member 4 is provided in the slide mechanism 2 and is configured to move in the axial direction together with the mounting table 1. The support member 4 is disposed between the mounting table 1 and the holding member 3. As shown in FIG. 1, the support member 4 includes a rotating body 41 and a shaft 42, and is configured to support the winding shaft 150 by the rotating body 41. The rotating body 41 is formed in a shape such that the upper bases of the two truncated cones face each other, and is rotatably provided at the tip of the shaft 42. The shaft 42 is provided so as to be rotatable about the base end.

-Operation-
Next, with reference to FIGS. 1-11, operation | movement of the extraction apparatus 100 by this embodiment is demonstrated. In the state before the operation is started, the mounting table 1 is arranged at the receiving position P2 (see FIG. 4) by the slide mechanism 2.

  First, when the rolled roll 170 is made in the rewinding device (not shown), the mounting table 1 moves in the Z1 direction so that the surface of the mounting table 1 is aligned with the roll discharge path 51 as shown in FIG. Rise). At this time, in the holding member 3, the tip of the upper arm 31 faces upward, and the tip of the lower arm 32 faces downward. Moreover, in the support member 4, the front-end | tip of the shaft 42 has faced the downward direction, and the rotary body 41 is arrange | positioned below. The pair of support plates 11 are disposed on the outer side in the axial direction (the side far from the roll 170), and the pressing member 12 is retracted from the surface of the mounting table 1.

  When the roll 170 is discharged in the Y1 direction from the roll discharge path 51 of the rewinding device, the roll 170 is mounted on the mounting table 1. After that, as shown in FIG. 2, the mounting table 1 is moved (lowered) in the Z2 direction, and the winding shaft 150 of the roll 170 is disposed at a predetermined height position P1. The height position P <b> 1 is a position where the winding shaft 150 is held by the holding member 3.

  Next, as shown in FIG. 3, in the holding member 3, the upper arm 31 is rotated downward and the lower arm 32 is rotated upward. For this reason, the end of the winding shaft 150 on the X2 direction side is sandwiched by the holding member 3. Further, the shaft 42 of the support member 4 is rotated, and the rotating body 41 is brought into contact with the lower end of the winding shaft 150. Further, the support plate 11 is moved inward (side approaching the roll 170) by the air cylinder 11a. Thereby, the support plate 11 is brought into contact with both end surfaces of the plurality of rolls 170, and the roll 170 is sandwiched between the pair of support plates 11 in the axial direction.

  At this time, as shown in FIG. 4, the winding shaft 150 is supported by the rotating body 41 between the holding member 3 and the mounting table 1. Then, as shown in FIG. 5, the mounting table 1 and the support member 4 are moved in the X1 direction by the slide mechanism 2. That is, the mounting table 1 is moved from the receiving position P2 to the discharging position P3. For this reason, the roll 170 is extracted from the winding shaft 150 by moving the roll 170 together with the mounting table 1 in the X1 direction. That is, the roll 170 is extracted from the winding shaft 150 in a state where the winding shaft 150 is supported by the support member 4 that moves together with the mounting table 1. The rotating member 41 of the support member 4 is in contact with the take-up shaft 150 and is rotated when the support member 4 moves in the X1 direction. Further, since the roll 170 is sandwiched between the support plates 11, the roll 170 extracted from the winding shaft 150 is prevented from falling.

  Here, in the winding shaft 150 from which the roll 170 has been extracted, the end portion on the X2 direction side is held by the holding member 3, and the end portion on the X1 direction side is supported by the support member 4. Thereby, it is possible to suppress bending compared with the case where the winding shaft 150 is cantilevered.

  Next, the pair of support plates 11 are moved outward (side away from the roll 170), and the roll 170 is discharged. Then, as shown in FIG. 6, a plurality of new cores 160 a are mounted on the mounting table 1. Thereafter, the pressing member 12 is rotated, and the new winding core 160 a is pressed against the mounting table 1 by the pressing member 12. Then, the mounting table 1 is moved (raised) in the Z1 direction so that the axis of the new winding core 160a coincides with the axis of the winding shaft 150.

  Next, as shown in FIG. 7, the mounting table 1 and the support member 4 are moved in the X2 direction by the slide mechanism 2. That is, the mounting table 1 is moved from the discharge position P3 to the receiving position P2. For this reason, the new core 160a is fitted onto the take-up shaft 150 by moving the new core 160a together with the mounting table 1 in the X2 direction. That is, the new winding core 160 a is fitted into the winding shaft 150 in a state where the winding shaft 150 is supported by the support member 4 that moves together with the mounting table 1. The rotating body 41 of the support member 4 is in contact with the take-up shaft 150 and is rotated when the support member 4 moves in the X2 direction. Further, as shown in FIG. 8, since the new core 160 a is pressed by the pressing member 12, the new core 160 a fitted into the winding shaft 150 is not easily displaced in the axial direction.

  As shown in FIG. 9, the holding of the winding shaft 150 by the holding member 3 is released, and the support of the winding shaft 150 by the support member 4 is released. Specifically, in the holding member 3, the upper arm 31 is rotated upward and the lower arm 32 is rotated downward. Moreover, in the support member 4, the rotating body 41 is arrange | positioned below by rotating the shaft 42 below. As a result, the new winding core 160 a is fitted, and the winding shaft 150 mounted on the mounting table 1 can be raised and lowered without being interfered by the holding member 3 and the support member 4. Thereafter, as shown in FIG. 10, the mounting table 1 is moved (lowered) in the Z2 direction.

  Then, as shown in FIG. 11, the pressing member 12 is rotated and retracted from the surface of the mounting table 1, and the holding of the new core 160 a by the pressing member 12 is released. Thereafter, the mounting table 1 is swung so that the Y2 direction side of the mounting table 1 moves downward, and the winding shaft 150 into which the new winding core 160a is fitted is sent to the winding shaft supply path 52 of the rewinding device.

-Effect-
In the present embodiment, as described above, by providing the support member 4 between the mounting table 1 and the holding member 3, when the roll 170 is pulled out from the take-up shaft 150, the take-up shaft 150 is moved by the support member 4. In addition to supporting, the winding shaft 150 can be supported by the support member 4 when the new winding core 160 a is fitted into the winding shaft 150. Thereby, it can suppress that it bends compared with the case where the winding shaft 150 is cantilevered. Therefore, it is possible to prevent the roll 170 from being loaded when the winding shaft 150 is pulled out, and to easily insert the winding shaft 150 into the new core 160a.

  In the present embodiment, since the support member 4 includes the rotating body 41, sliding resistance at the support member 4 when the support member 4 is moved together with the mounting table 1 can be suppressed.

  Further, in the present embodiment, by providing the pressing member 12 that presses the new core 160a, it is possible to prevent the new core 160a from shifting when the new core 160a is fitted into the winding shaft 150.

  Moreover, in this embodiment, by providing the support plate 11 that supports the end face of the roll 170, the roll 170 extracted from the winding shaft 150 can be prevented from falling.

  Moreover, in this embodiment, since the winding stand 150 can be arrange | positioned by comprising the mounting base 1 so that raising / lowering is possible, the diameter of the roll 170 wound up with a rewinding apparatus differs. Even if it is a case, it can respond appropriately.
