Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement in the storage method of anti-snow rings that are attached to electric wires at regular intervals to prevent snow from accumulating on the electric wires.

<Prior Art> Anti-snow rings generally have a ring shape with a cut of an appropriate length, and are attached to electric wires by caulking or fitting the open end.

For this reason, the ring itself has flexibility, making it difficult to automatically take it out and store it during automatic attachment.

As a means to solve this problem, conventionally, a large number of T-shaped ring holding pieces are attached to the inside of the drum-shaped ring storage case at equal intervals in the longitudinal direction of the drum, and the ring is held between the T-shaped ring holding pieces. A method has been proposed in which the ring is sent out from the rear of the ring storage case using an air cylinder.

However, according to this method, in order to increase the number of rings stored, it is necessary to make the ring storage case thicker or longer. However, when making it thicker, the ring storage area is only on the inner circumference of the case, so the storage capacity does not increase even though the volume increases.
If the length is increased, the air cylinder for sending out the ring must also be lengthened, resulting in problems such as an increase in the size of the device.

Therefore, the inventors of the present invention devised a device that attaches a ring to a tape and stores the tape by winding it around a reel, as in Utility Model Application No. 190955/1983 (Kokai No. 97335/1983).

However, in the device proposed in Utility Model Application No. 190955/1987, the rings are not positioned on the tape, so if the rings fall off the tape or are lined up on the tape, the alignment dimensions (pitch) of the rings will remain constant. If an automatic ring feeding and caulking device were to be manufactured without this, problems such as complicated mounting would be expected.

<Problems to be solved by the invention> The invention in this case was made to solve the above-mentioned problems.In addition to storing a large number of rings in a compact and lightweight device, it also solves problems such as rings falling off from the tape. The purpose of the present invention is to provide a ring storage device in which there is no problem, the pitch of the rings is kept constant, and there are fewer problems in manufacturing an automatic feeding or crimping device.

<Means to solve the problem> Therefore, the invention of this case is based on the conventional Utility Application No. 61-190955.
In addition to the above structure, a convex part for positioning the ring is formed on the tape at an accurate pitch, a corresponding concave part is formed on the ring, and the convex part and concave part are combined to attach the ring to the tape. be.

<Function> When the notched groove provided on the ring hinge is fitted onto the tape while aligning the concave portion provided on the outer periphery of the ring with the convex portion provided on the tape, the ring will not come off from the tape and will fit into the convex portion of the tape. The concave part on the outer circumference of the ring gets caught and the ring can be fixed without moving on the tape.If the convex parts on the tape are arranged continuously at a pitch slightly wider than the thickness of the ring,
Rings can be held efficiently and continuously.

The tape to which the ring is attached is flexible, so the ring becomes stiff on the ring side and cannot be bent, but the tape side can be bent, with the tape on the inside and the ring on the outside. west,
Can be stored in a spiral shape.

When removing the ring from the tape, when attaching the ring to the wire, the open end of the ring is closed, so the notch groove in the ring hinge part widens, allowing for easy removal.

<Example> Reference numeral 1 is a snow-resisting ring of the present invention, which is a flexible ring having a thickness a and having a cut.

One end of the cut has a protrusion 2, and the other end has a notch 3 into which the protrusion can be pushed and gripped.

4 is a concave portion provided on the outer periphery of the ring having a width b, and 5 is a hinge portion formed thinly.

6 is a notch groove provided in the hinge part, width c, thickness d
A gap with an opening width e that is open on one side is formed. 7 is an inclined surface.

Reference numeral 8 denotes a tape having a thickness f which is somewhat thinner than the thickness d of the notched groove, and a narrow portion 9 having a width g which is somewhat smaller than the width c of the gap formed by the notched groove and somewhat larger than the opening width e.
and the width h, which is slightly smaller than the width b of the recess on the outer periphery of the ring.
It consists of a convex portion 10.

The convex portions having a width h are repeatedly formed at a pitch i that is slightly larger than the thickness a of the ring.

To combine the ring and tape configured as described above, first, roughly align one convex portion 10 of the tape with one of the concave portions 4 provided on the outer periphery of the ring, and then place the tape in the notch groove 6 of one of the rings. When one end of the narrow part 9 is fitted and the tape is pressed against the ring, the tape and ring will deform along the slope 7, and the end of the narrow part of the other tape and the convex part will form a notch in the ring. The tight dust is inserted into the groove 6 and the recess.

Alternatively, the convex part 10 of the tape can be inserted into the concave part 4 provided on the outer periphery of the ring, and the tape narrow part 9 can be inserted into the notch groove 66.
If both ends of the ring are aligned and the tape is pressed against the ring, both the tape and the ring will be deformed and assembled by the action of the inclined groove 7.

By repeating this process, the rings will be neatly fixed on the tape.

The ring thus attached is inserted into the narrow part 9 of the tape in the gap formed by the notch groove 6 of the ring.
is inserted securely, and the convex part 1 is inserted into the concave part 4 on the outer periphery of the ring.
Since 0 is inserted, it does not move on the tape or come off the tape.

Since the tape to which the ring is firmly fixed in this way is flexible, the ring gets in the way on the ring side and cannot be bent, but the tape side can be bent.

Therefore, by winding a tape with a large number of rings around the reel 11, a large number of rings can be stored without taking up storage space.

No special operation is required to remove the ring from the tape.When attaching the ring to the wire, insert the wire into the ring through the cut in the ring, push in the protrusion 2 and notch 3, and press the ring opening. When narrowing, the opening width e of the cutout groove provided in the hinge automatically widens, and the ring is removed from the tape.

<Effects of the invention> According to the present application having the above structure, the concave part of the ring and the convex part of the tape can be aligned without losing the feature of Utility Model Application No. 61-190955, which enables efficient storage of the anti-snow ring. By aligning the tape and fitting the narrow part of the tape into the cutout groove of the ring, the ring will not fall off the tape, and the convex part of the tape can be accurately formed with a press or the like. The rings can also be fitted onto the tape in an accurate alignment at the same pitch, and an accurate tape and ring feeding means can be constructed.
