The long belt-like member is handled as a belt-like member roll by being wound around a tubular core material. And a strip | belt-shaped member roll winds or takes out a strip | belt-shaped member by attaching to a rotatable shaft. The shaft integrally holds the belt-shaped member roll by fixing both ends of the core material of the belt-shaped member roll.
[0003]
This type of conventional belt-shaped member roll mounting device will be described with reference to FIGS. 4 is a block diagram showing a conventional belt-shaped member roll mounting device, FIG. 5 is a front view showing a bearing portion at the other end of the shaft, FIG. 6 is a half sectional view of the lock nut shown in FIG. 4, and FIG. FIG. 8 is a front view of the collar viewed from the axial direction of the shaft. The casing 1 of the apparatus supports one end of a shaft 5 via a bearing 3 so as to be rotatable. Further, the casing 1 supports the other end of the shaft 5 through a U-shaped bearing groove 7 (see FIG. 5) so as to be rotatable and detachable.
[0004]
The shaft 5 has a driven gear 9 fixed on the outer periphery on one end side, and the driven gear 9 meshes with a drive gear 13 of a rotary drive device (electromagnetic clutch) 11 attached to the casing 1. The shaft 5 can be inserted through the belt-shaped member roll 15 by detaching the other end side from the bearing groove 7. The shaft 5 has a male screw 17 formed on the outer periphery. The shaft 5 has a set of a lock nut 19 and a collar 21 screwed to the male screw 17. The collar 21 has a female screw 23 on the inner periphery, and has a conical insertion portion 27 and a flange portion 29 that are inserted into and contacted with the core member 25 of the belt-like member roll 15 on the outer periphery.
[0005]
As a procedure for attaching the belt-shaped member roll 15 to the shaft 5, first, the other end side of the shaft 5 is removed from the bearing groove 7, and the lock nut 19 and the collar 21 screwed to the other end of the shaft are removed from the shaft 5 while rotating. Next, the belt-like member roll 15 is inserted from the other end side of the shaft 5, the collar 21 and the lock nut 19 are screwed again to the other end of the shaft, and then the other end of the shaft is supported by the bearing groove 7.
[0006]
A lock nut 19 and a collar 21 screwed to one end of the shaft 5 are tightened in the approaching direction and fixed to the shaft 5 with a so-called double nut structure. Next, after one end of the core member 25 of the belt-shaped member roll 15 is brought into contact with the fixed collar 21, the other collar 21 is rotated and brought into contact with the other end of the core member 25 to perform tightening. . After completing the tightening of the other collar 21, the lock nut 19 is further tightened to this collar 21, and the collar 21 is fixed to the shaft 5 with a double nut structure in the same manner as described above. The lock nut 19 and the collar 21 are tightened by engaging jig claws (not shown) in jig holes 19a and 21a formed on the outer periphery.
[0007]
According to the belt-shaped member roll mounting device configured as described above, the belt-shaped member roll 15 having an arbitrary length can be detachably mounted at a desired position of the shaft 5.

[Problems to be solved by the invention]
However, in the conventional belt-shaped member roll mounting device described above, the male screw 17 is formed over a long distance of the shaft 5 in order to correspond to various belt-shaped member widths. In addition, the collar 21 must be removed from the shaft 5 while rotating, which has been a factor in reducing the workability of replacing the belt-shaped member roll 15.
[0009]
In addition, since the conventional belt-shaped member roll mounting device has a double nut structure for tightening the lock nut 19 and the collar 21, the lock nut 19 and the collar 21 are further tightened by the rotation of the shaft 5, and the lock is used unless a jig is used. The nut 19 and the collar 21 may not be unlocked.
[0010]
Furthermore, since the shaft 5 did not have any means for positioning the belt-shaped member roll, it was extremely difficult to adjust the position.
[0011]
The present invention has been made in view of the above situation, and provides a belt-shaped member roll mounting device capable of fixing a belt-shaped member roll to a shaft regardless of the double nut structure, and improving workability when the belt-shaped member roll is attached / detached. It aims to plan.
