Description

[Detailed Description of the Invention] This invention relates to a storage device for perforated products, such as a storage device for sleeves and rings of pipe joints used in semiconductor film-forming gas supply pipes and exhaust pipes.

Sleeves and rings of pipe joints used for semiconductor film-forming gas supply pipes and exhaust pipes (Utility Model No. 48-
(see Publication No. 100419) were conventionally stored in a state that was fitted to the outside of a paper core. However, the paper core was weak and often broke. In addition, the powdery waste that floats on the surface of the paper core adheres to the sleeve and ring, so this paper waste must be removed when using the sleeve or ring.
The work was troublesome.

This invention was made in view of the above-mentioned circumstances, and provides a storage device for perforated items that is strong, hard to break, and does not produce powdery paper waste like a paper core.

The device for storing perforated items according to this invention includes a perforated item holding rod made of synthetic resin or metal into which the perforated item is fitted on the outside, a stopper provided at one end of the perforated item holding rod, and a perforated item holding rod made of synthetic resin or metal. The perforated article retainer made of an elastic material is attached to the other end of the holding rod and at least a portion thereof protrudes outside the perforated article holding rod.

The perforated product holding rod is made of synthetic resin or metal, but synthetic resins include vinyl chloride, trifluoroethylene resin, tetrafluoroethylene resin, polyethylene,
ABS resin etc. are used, and the metals are alloy steel,
Carbon steel, nonferrous alloys, etc. are used.

The device for storing perforated items according to this invention is equipped with a perforated item holding rod made of synthetic resin or metal.
A perforated article is fitted on the outside of this perforated article holding rod. The perforated product holding rod is made of synthetic resin or metal, so it is strong and does not easily break. Also, unlike paper cores, powdery paper waste does not come out, so there is no need to worry about powdery paper waste adhering to perforated items. In addition, there is no need to remove the retaining ring from the perforated product when fitting the perforated product into the perforated product holding rod and when removing the perforated product from the perforated product holding rod, so handling is easy.

Embodiments of this invention will be described below with reference to the drawings.

This storage device stores sleeves S and rings R of pipe joints used for semiconductor film-forming gas supply pipes and exhaust pipes. It includes a holding rod 1, a collar-shaped stopper 2 formed at one end of the holding rod 1, and a retaining ring 3 attached to the other end of the holding rod 1. Holding rod 1 and stopper 2
is made of vinyl chloride, and both are integrally molded. The retaining ring 3 is made of rubber. The sleeve S has a short cylindrical shape, and the ring R has an annular shape.

An annular groove 1a is formed on the peripheral surface of the other end of the holding rod 1. A retaining ring 3 is fitted into this annular groove 1a. The outer peripheral surface of the retaining ring 3 is formed in a concave and convex shape, and the tip of the convex part is
It protrudes to the outside of the holding rod 1.

The inner diameters of the sleeve S and ring R are approximately equal. The outer diameter of the holding rod 1 is slightly smaller than the inner diameters of the sleeve S and the ring R. The outer diameter of the stopper 2 is larger than the inner diameters of the sleeve S and ring R. When the retaining ring 3 is attached to the holding rod 1, the outer diameter of the portion of the holding rod 1 that protrudes outward is slightly larger than the inner diameters of the sleeve S and the ring R.

In order to store the ring R and the sleeve S in such a storage device, the ring R and the sleeve S may be fitted alternately to the outside of the holding rod 1 from the other end of the holding rod 1. The retaining ring 3 is made of rubber, so if you pinch the ring R or sleeve S, fit it onto the other end of the holding rod 1, and feed it toward one end of the holding rod 1, the ring R or sleeve S will be removed. , retaining rod 1 in retaining ring 3
While compressing the outwardly projecting portion inward, it passes over the retaining ring 3 and is fitted into the retaining rod 1 on one end side of the retaining ring 3. The retaining ring 3 returns to its original state when the ring R and sleeve S pass through it. The ring R and the sleeve S are stored in a state where they are fitted to one end of the retaining rod 1 relative to the retaining ring 3.

In this state, for example, even if the other end of the holding rod 1 is directed downward, of the ring R and the sleeve S fitted to the holding rod 1, the one closest to the other end of the holding rod 1 will not come off. Since the ring 3 is caught on the portion of the retaining rod 1 that protrudes outward, the ring R and the sleeve S do not fall off the retaining rod 1. When using the ring R and sleeve S, it is sufficient to pinch them and pull them out from the other end of the holding rod 1.

In the embodiment described above, the other end of the holding rod is formed in an annular shape, but this annular groove may be omitted. In this case, a retaining ring may be attached to the outer peripheral surface of the other end of the holding rod. If the outer diameter of the retaining ring is larger than the outer diameter of the holding rod and slightly larger than the diameter of the hole in the perforated product, the outer surface of the retaining ring may be flat. Alternatively, the outer surface of the retaining ring may be formed into a flat shape, and tapers may be formed on both sides of the outer surface of the retaining ring. Although the stopper is formed integrally with the holding rod, the two may be manufactured separately and the stopper may be adhered or welded to one end of the holding rod. Alternatively, the stopper may be detachably attached to the holding rod. Further, characters indicating the diameter of the perforated product to be stored may be engraved on the outer end surface of the stopper, or a label with those characters written may be attached. Furthermore, a tag attachment piece having a hole for attaching a tag to the stopper may be provided. The holding rod may be pipe-shaped. The structure for removably attaching the stopper to the retaining rod is one in which a recess is formed into which one end of the retaining rod is tightly fitted, and if the retaining rod is pipe-shaped, it is fitted into the hollow part of the retaining rod. A male thread is cut on the outer circumferential surface of the protrusion, and a female thread is cut on the inner circumferential surface of the hollow part at one end of the holding rod to engage with this.
There are some that can be screwed onto the retaining rod. Among these, the stopper with a recess and the stopper with a protrusion are preferably made of rubber.

It goes without saying that this invention can also be applied to storing perforated items other than sleeves and rings of pipe joints, such as E-rings, snap rings, nuts, etc.
