Abstract

PURPOSE:To surely support the core of a sheet belt co-axially with a rotary shaft and to stably wind the sheet belt by providing the notch part formed with inclination on each equal interval on the projection part between fitting grooves. CONSTITUTION:A ring 28 is turnable for a collar main body 14 and a roller 36 is rolled on the inclined bottom face 38 of a notch part 24 by being supported in the axial direction all the time by the recessed part 34 of the ring 28. At this time, four rollers 36 are linked to the ring 28 and rolled on the inclined bottom face 38 simultaneously by the rotation of the ring 28. The four rollers 36 bond the paper tube outer-inserted on the collar 14 outer periphery by pushing it up only at the time located at the shallow position of the inclined bottom face 38. Consequently, the paper tube is surely supported with good stability and no paper tube is biased nor slided in the axial direction while under winding the sheet belt.

[Prior Art and Problems to be Solved by the Invention] Conventionally, a winding shaft for a sheet band consists of a drive shaft and a plurality of collars extrapolated to the drive shaft in a frictionally transmittable manner.
When a plurality of recesses each having an inclined bottom surface are provided on the outer periphery of the collar at equal intervals in the circumferential direction, a rolling element is mounted in the recesses so as to roll on the inclined bottom surface, and a winding core is inserted into the collar,
It has been proposed that the collar and core are connected only when the rolling element is at a shallow position on the inclined bottom surface.

As a means for rollingly mounting the rolling elements in the recesses of the collar, for example, the rolling elements are fitted in the four parts so as to be rollable, and an annular ring is placed outside the collar to prevent the rolling elements from coming off from the four parts. Is there something set up? This method has the problem that it is necessary to provide an annular ring outside the collar to prevent the rolling element from coming off, making the structure complicated. Further, since the plurality of rolling elements roll on the inclined surface and do not protrude from the outer periphery of the collar at the same time, there is a risk that the core will not be extrapolated coaxially with the drive shaft. Furthermore, there was a problem in that the rolling element moved in a direction other than the rolling direction inside the recess, and the outer core moved during the winding operation, making it impossible to wind the sheet band neatly.

Other methods of installing rolling elements include those in which the rolling elements are irremovably fitted into recesses, or with this method, when the rolling elements are worn out, it is difficult to remove them from the recess and it is difficult to remove the rolling elements from the recess. It was difficult to replace it with a moving object.

[Means for Solving the Problems] In the winding shaft of the present invention, two fitting grooves are provided in the circumferential direction on the outer periphery of the main body of the collar, and the protrusions between the fitting grooves are provided with equal intervals. A notch is provided in each of the rings, and the bottom surface of the notch is formed to be inclined with respect to the tangential direction, and a ring is rotatably fitted into the fitting groove, and a notch on the opposing surface of the ring is fitted into the fitting groove. Four parts are provided in corresponding positions,
A pin is fitted between both ends of a cylindrical roller that rolls on an inclined bottom surface or into a recessed portion, and is inserted into a hollow portion of the roller so as to allow the roller to roll on the inclined bottom surface, and is installed between the four parts, The collar and core are combined only when the roller is at a shallow position on the inclined bottom surface.

[Function] The winding shaft configured as described above is configured to push up and couple the winding core inserted around the outer periphery of the collar only when the roller is at a shallow position on the inclined bottom surface. Therefore, when the collar is rotated while applying rotational resistance to the winding core, the plurality of rollers simultaneously move from a deep position to a shallow position on the inclined bottom surface, and the winding core and collar are coupled by frictional coupling. Turning the collar in the opposite direction loosens the connection and allows the core to be removed. In addition, since both sides of the roller are not always supported in the axial direction by the concave part of the ring, but instead roll on the inclined bottom surface of the notch, the core can be stably inserted without swinging in the axial direction of the roller. can.

(36) is a cylindrical roller that rolls on the inclined bottom surface (38) of the notch (24), and is placed on both sides of both concave portions (34) of the ring (28) fitted in the fitting groove (22). The two recesses (34) are fitted together with pins (40) installed in both the recesses (34). The inner diameter of the roller (36) is larger than the outer diameter of the pin (40). Since the ring (28) is rotatable relative to the collar body (14a), the ring (28) is rotatable relative to the collar body (14a).
Since the roller (36) is always supported in the axial direction by the recess (34) of the notch (28), the inclined bottom surface (38) of the notch (24)
) to roll. At this time, since the four rollers (36) are connected to the ring (28), the rotation of the ring (28) causes the four rollers (36) to simultaneously rotate the inclined bottom surface (38).
rolling. Moreover, since the pin (40) is loosely inserted into the roller (36), the roller (36) can slide in the radial direction. When the four rollers (36) are at a shallow position on the inclined bottom surface (38), they push up and couple the paper tube (16) inserted around the outer periphery of the collar (14). In other words, the four rollers (36) drawn with solid lines in Fig. 3 are located deep on the inclined bottom surface (38), and even though they protrude from the outer peripheral surface of the collar (14), there is no play between them and the paper tube (16). The following is
When this is transferred to a roller (36°) indicated by a chain line at a shallow position on the inclined bottom surface (38), the inner surface of the paper tube (16) is reliably pushed up. Therefore, if rotational resistance is applied to the paper tube (16) and the collar (■4) is turned clockwise as shown in Fig. 3, the four rollers (3B) will simultaneously move (36) due to the rotation of the ring (28). ”) and attach the paper tube (16) by frictional connection.

(46) is a cylindrical suppressing member that slides inside the suppressing hole (44), the tip is formed in a hemispherical shape, and a backing (48) is fitted on the outer peripheral surface. To connect the drive shaft (12) and collar (14), high pressure air is fed into the air pressure inlet passage (42), and the tip of the suppression member (46) slightly protrudes from the outer peripheral surface of the drive shaft (12). Color (14)
push up the inner surface of the material and connect them by frictional bonding. The bonding force changes depending on the air pressure, and when the high pressure air is cut off, the suppressing member (
46) is no longer pressed against the collar (14), and the frictional bonding force is also eliminated. With the conventional method of moving the pressing member in the axial direction of the collar, there was a risk that high-pressure air leaked during the winding process and the binding force suddenly disappeared, damaging the sheet band (A). If there is, high pressure air will not leak and there is no risk of damage to the sheet band (A).

[Effects of the Invention] As described above, the winding shaft of the present invention has a roller that is always supported in the axial direction by four parts, and a plurality of rollers that simultaneously roll on an inclined surface and protrude from the outer periphery of the collar. The winding shaft and the winding core are in the same window, so there is no vibration during winding, and the winding core is reliably and stably supported, and the winding core is not biased, shifts in the axial direction, or slips while winding the sheet band. The tension never changes. Further, even if the winding core has a narrow width, it can be reliably supported because it is supported by the rollers. Further, since both sides of the roller are held by rings, a plurality of rollers can simultaneously roll on an inclined surface by rotation of the ring, and the structure is simple.
