After that, the upper flow path 53 of the cylinder 44
Pressure oil is sent from the upper chamber 46 to the upper chamber 49 to raise the upper pawl member 39 and lower the lower pawl member 40 to lower the pawl member 41 fitted to the upper pawl 41 and the lower pawl 42. , 15 so that the dimension between the recesses 18, 18 is slightly larger than the required diameter of the roll 14. Next, the moving hydraulic cylinder 32 is operated to move the roll 14 to the predetermined position to which the clasp type clasp 13 is clasped, as shown in FIG. 8B. And the cylinder 44
Pressure oil is sent from the lower flow passage 54 to the lower chamber 47 and the pressure oil in the upper chamber 46 is drained from the upper flow passage 53, and the upper rod 4
By lowering 9, the upper pawl member 39 is lowered,
The lower pawl member 40 rises and the grasping type cleats 13 are separated from the automatic grasping type kelp attaching / detaching device 24, and the grasping type kelps 13 are coiled with a coil spring 17 as shown in FIGS. 2, 4 and 8 (c). It is attached to the roll 14 by the urging force of.

Further, pressure oil is supplied from the lower flow path 54 to the lower chamber 47.
8 to lower the upper rod 49, remove the upper pawl 41 and the lower pawl 42 from the fitting portion 22 of the clamping member 15, and operate the moving hydraulic cylinder 32 to move the upper pawl member to the upper pawl member as shown in FIG. 39 and the lower pawl member 40 are removed from the clasp-shaped breaker 13.

When the clinging type kerbs 13 are to be detached from the roll 14, they can be detached by performing the operation opposite to the above.

[0027]

As described above, the clasping type clasp according to the present invention has a pair of clasping members that grip the roll-shaped work from both sides in the direction perpendicular to the axial direction, and these clasping members adhere to the roll-shaped work. Since the clasping member is clamped to the roll-shaped work by providing a biasing means for causing the roll-shaped work to be clamped automatically, it is possible to automatically clamp the scrapes, and moreover, with one scraper for a plurality of roll-shaped works. Can be adapted. In addition, the automatic attachment type attachment / detachment device holds a plurality of attachment type attachments,
A scraping holder having an opening / closing mechanism that expands the sandwiching member against the biasing means, and a swivel mechanism that automatically selects the sandwiching type scrape and swivels it on the axis of the roll-like work in order to mount it on the roll-like work. Since it is equipped with a moving mechanism to move the selected clasp type kere to a predetermined position on the outer peripheral surface of the roll-shaped work, unmanned operation is possible without the operator's hand for the clinging of the kele. Becomes

Moreover, since all can be automated, there is an excellent effect that the working time is shortened and the working efficiency is greatly improved.
