JPS6331961A - Rotary drive shaft for core with rib used in sheet wind-up operation - Google Patents

Abstract

PURPOSE:To make it possible to set the insertion of ribs of a plastic spool in recesses to prevent eccentricity, by surrounding the outside of a rolling member projecting from an inclined groove in a drive shaft, with a ring-like wheel having a slot at one position and formed therein with several triangular protrusions and recesses which are parallel with the axial direction. CONSTITUTION:When a body is rotated clockwise, a transmission wheel 3 is rotated integrally with the body 1 while a grooved wheel 5 is started to be rotated in the same direction due to the friction between itself and the transmission wheel 3, and a rolling member 6 positioned in the deep section of an inclined groove 4 rolls toward the shallow section 4a of the groove 4 due to the friction between a ring-like wheel 8 and the inclined groove 4 under the tension of a sheet belt so that it projects from the inclined groove 4 to a large extent. Further, the ring-like wheel 8 surrounding a holder 7 is moved together in the direction reverse to the rotating direction, rolling in the groove toward the shallow section, and is pushed outward by the rolling member projected from the groove to enlarge a slot 9 so that the outer periphery of the ring-like wheel 8 is engaged with the inner periphery of a core 13 to rotate the core integrally with the grooved wheel 5, thereby the sheet belt is wound up on the outer periphery of the core. Then, in order to set ribs 29 of the ribbed core 13 in recesses 31, if the ribs 29 are set in recesses nearest to the ribs 29 by slightly rotating the core 13 right and left, there may be no eccentricity.

当業者は熟知していることである。<Problems to be Solved by the Invention> -1-1 The winding drive shaft directly rotates a right-handed sheet band on its outer periphery or integrally drives a ribless winding core. 1- There is no problem in winding ':::', and there is no problem in winding the winding core (for example, ribbed plastic pipe). When used as a core, if one rib provided in the axial direction of the inner periphery is inserted and set on the 2-winding rotation drive shaft, the rig part will not be able to hold a perfectly round person and it will become eccentric. Those skilled in the art are well aware that this 1"11 core has a negative effect on the winding quality.

If the rolling elements are made to be larger, the inner diameter will be larger than the outer diameter of the annular ring when the rolling element is in the deep part (1γ11). However, by supporting it concentrically on the drive shaft, it can be rotated more smoothly.

向きに動き１巻芯の内周から離れる。After winding the seal band to the required length or length around the outer circumference of the winding core, stop the I-beat, remove the drive shaft from the gap, grasp the end of the main body of the drive shaft, and tighten the sheet band. Rotate the winding core twice or twice in the direction in which the rolling elements roll into the deep part of the inclined groove. As a result, initially, the annular ring 8 rotates together with the winding core to roll the rolling element 6 toward the deep part of the inclined groove, and as the rolling element approaches the deep part, the rolling element 6 rotates together with the winding core. When 7+ becomes smaller, the white bullets move inward in the radial direction due to the contraction force of the retaining material and separate from the inner periphery of the core.

従って１．駆動軸を巻芯から引抜けばよい。Therefore 1. All you have to do is pull out the drive shaft from the winding core.

The width of the annular ring is completely narrowed and many are fitted adjacent to each other on the main body of the drive shaft, and the transmission wheel is integrated with the main body, so that the γ11IT ring and toe rotate in the same direction as the transmission wheel due to friction. The longer the winding core is, the greater the number of annular rings in the axial direction that fit the winding core around its outer periphery, which allows the winding core to be rotated and driven with a predetermined winding torque depending on the length of the winding core.

また、保持器７を別に設けて転動体６相互の間隔を保つ

When the rolling element rotates in a pairwise manner (11), when the inner periphery of the first core and the annular element are uncoupled, the rolling element quickly rolls into the deep part due to the contractile force of the annular element and the attractive force of the magnet. Note that even if the rolling element is removed once the ring is removed, it will not fall off because it is attracted to the deep part by the magnet piece.

It can also be used to wind up a sheet band by attaching it to an arm and attaching a winding core to its outer periphery.Although it is most desirable that the intervals between each inclined groove be equal, it is possible to They may be equally spaced. Additionally, it is desirable that the rolling elements accurately roll in the circumferential direction on the circumferential line of the shaft.
It may also be configured to roll in the circumferential direction with some deviation in the axial direction.

したものである。The device of the present invention has a split in one place that surrounds the outside of the rolling element, which is easy to manufacture and install, and does not cause eccentricity.
Since it is an annular ring with many unevenness parallel to the axial direction,
Compared to the conventional method using an annular ring with a split in one place, this method eliminates the disadvantage of eccentricity due to local lips, which has a significant effect on the quality of one winding, and in addition to the conventional effects. By providing a large number of four parts that can evacuate the lips that cause eccentricity, it is possible to avoid eccentricity caused by the lips and maintain a perfectly circular state.Moreover, there is only one four part that fits the lip part. However, since there are a large number of them, the four parts can be easily set to suit the lip by rotating forward and backward at negative angles, which greatly improves the operability.
