Claims

[Claims for Utility Model Registration] An air shaft for holding a core tube around which a sheet-like object is wound, wherein a plurality of claws are attached to the circumferential surface of the holding shaft, which is an outer tube of the air shaft, to hold the core tube. In the tube type air shaft, which holds a core tube into which the air shaft is inserted by causing the claws to protrude radially from the holding shaft by air pressure applied to the air tube inside the shaft, the holding shaft 4 is provided with the air tube 2 and the claws 3. is the slide shaft 5 that penetrates inside it.
is held by the slide shaft 5, and is held with only rotation R allowed without reciprocating with respect to the slide shaft 5,
The slide shaft 5 is held at both ends by bearings 10 so that it can only reciprocate S, and the core tube 8 is held by the air shaft 1 and lets out the sheet-like body 9.
It rotates R for winding, and at the same time, it is possible to unwind the sheet-like body 9 and reciprocate S with respect to the bearing 10 in the lateral direction X with respect to the winding direction Y, and external operation is possible between the bearing 10 and the slide shaft 5. An adjustment mechanism is provided to adjust the slide shaft 5.
A tube type air shaft, characterized in that the reciprocating motion S of the air shaft can be adjusted and its adjustment width Δd can be controlled from the outside. The adjustment mechanism includes a rotation/reciprocating conversion means 7, and in adjusting the reciprocating motion S of the slide shaft 5 with respect to the bearing 10, the rotation T is controlled by an external operation.
is converted into a reciprocating motion S of the slide shaft 5, and by manipulating the magnitude of the rotation angle of the rotation T, it is possible to manipulate the adjustment range Δd of the reciprocating motion S of the slide shaft 5. , claim 1
Section: Tube type air shaft. The rotation/reciprocating motion conversion means 7 includes an adjustment shaft 7a that penetrates the slide shaft 5, which is a tubular body, to allow only rotation T, a lead screw 7b provided at one end of the adjustment shaft 7a and protruding from the slide shaft 5, and a bearing 10. This is realized by a lead nut 7c fixed to the lead screw 7b and screwed into the lead screw 7b, and by operating the part of the adjusting shaft 7a protruding from the slide shaft 5 at the other end of the end where the lead screw 7b is provided to rotate T. The lead screw 7b rotates T and reciprocates S to move in and out of the lead nut 7c to which it is screwed, causing the slide shaft 5 to reciprocate S, and then the slide shaft 5 is rotated by the rotation T of the adjustment shaft 7a from the outside. 3. The tube type air shaft according to claim 2, wherein the reciprocating width Δd with respect to the bearing 10 is adjusted.
