Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small frame for reeling yarn, and more particularly to a small frame for reeling yarn that can extremely easily remove fallen yarn entangled in soft parts during reeling and can improve work efficiency.

As shown in FIG. 1, the small frame 10 that has been commonly used in the past has a ring 14 on one side of the thread receiver part 12 to prevent the thread from falling, and a small frame 10 on both ends of the soft part 16. Cylindrical bodies 20 a and 20 b having suppression pins 18 for connection to a rotating shaft (not shown) of an automatic reeling machine (not shown) are fitted.

22a. 22b always connects the pressing pin 18 to the cylindrical body 20a.

20b is a spring that urges inward to press the pressing pin 18 into contact with the rotating shaft.

The cylindrical body 20a on the ring 14 side is provided with a cylindrical flange portion 24 that covers the spring 22a in order to prevent the fallen thread from getting entangled with the spring 22a, as will be described later.

A large number of the small frames 10 are attached to the rotating shaft of an automatic reeling machine in series at certain intervals and are rotated.During this reeling, the traverse of the yarn is often It comes off to the side, falls onto the ring 14 side of the adjacent small frame 10, and tends to get entangled with the grain part 16 of the adjacent small frame 10.

In this case, since the cylindrical body 20a having the flange portion 24 larger than the outer diameter of the soft portion 16 is fitted into the soft portion 16 on the ring 14 side, the fallen threads will not get entangled with the small diameter soft portion 16 inside the flange portion 24. I end up.

When the thread becomes tangled, the machine is temporarily stopped and the thread is reconnected, but the tangled thread must eventually be removed.

This removal work requires cutting with a knife or the like, but the flange part 24, the thread receiver part 12, the ring 14, etc. become obstacles, and the area immediately inside the flange part 24 becomes a blind spot, making the work extremely difficult. Not only is this method difficult and the work efficiency is poor, but it also requires a huge amount of labor to process a large number of small frames.

The present invention has been made to solve the above-mentioned difficulties, and its purpose is to make it possible to extremely easily remove fallen threads entangled in soft parts,
A plurality of support arms extend radially from the grain section, and the thread receiver supported by the support arms is provided with a section, the outer peripheral section of which protrudes outward from the thread receiver section, which can improve work efficiency. A ring protruding outward from the thread receiving part is fixed to one end side of the thread receiving part, and a flange part having a larger diameter than the soft part,
A connecting mechanism provided on the outer periphery of the soft part to connect the soft part to an appropriate rotating shaft is provided at the end of the grain part on the ring side so as to cover from the outside, and on the outer periphery of the soft part between the flange part and the support arm,
A reeling yarn characterized in that a rib is provided integrally with the soft part and the support arm, the outer edge of which extends parallel to the grain axis or gradually descends from each support arm toward the flange part, and reaches the outer peripheral edge of the flange part. To provide a small frame for use.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The overall reference numeral 30 indicates a small frame according to the present invention, and the small frame 30 is entirely made of synthetic resin.

32 is a soft part, 34 is six supporting arms that stand up radially from this grain part 32, 36 is a reinforcing ring connecting the tips of the supporting arms 34, and 38 is a predetermined interval on the outer wall of the reinforcing ring 36. The thread receiver, which is erected in the shape of an impeller, is a part.

Reference numeral 40 denotes a ring connecting one end of the thread receiver section 38, and the outer periphery of the ring projects outward from the thread receiver section 38.

42a and 42b are cylindrical bodies, which are fitted onto both ends of the soft part 32.

44a and 44b are pressing pins, and the cylindrical body 42a.

Spring 4 is loosely fitted into each through hole bored in the outer wall of 42b and wound around the outer wall of the cylinder body 42a>42b
6 a and 46 b always make the cylinder 42 a t 4
2 b is inwardly biased, and an automatic reeling machine (not shown)
When the small frame 30 is inserted into the rotating shaft (not shown) of the rotating shaft, the tips of the press pins 44at44b come into pressure contact with the outer wall of the rotating shaft, thereby fixing the small frame 30 on the rotating shaft. When a predetermined load or more is applied to the frame 30, the rotating shaft will idle.

48 a t 48 b is the cylinder body 42 a t 42 b
It is a protrusion provided at the end of the spring 46
46b is prevented from separating from the cylinder body 42a and 42b.

Reference numeral 50 designates a flange portion provided on the cylindrical body 42a on the ring 40 side of the small frame 30, and is formed into a bottomed cylindrical shape having a bottom portion 52 in contact with the end portion of the grain portion 32, and supports the suppressing pin 44a and the spring 46a. It is covered from the outside to prevent the thread from falling and getting tangled on the spring 46a and the pressing pin 44a.

Reference numeral 54 denotes a rib erected on the soft portion 32 between the flange portion 50 and the support arm 34, one end of which is in contact with the outer bottom surface of the flange portion 50, and the other end is connected to the support arm 34.

The outer edge of the rib 54 gradually becomes higher inward from a position that is coincident with or slightly higher than the edge of the outer peripheral surface of the flange portion 50.

Alternatively, the outer edge of the rib 54 may be substantially parallel to the outer peripheral surface of the flange portion 50.

The present invention is configured as described above.

Next, to explain the operation of the present invention, as described above, a large number of small frames 30 are mounted in series on the rotating shaft (not shown) of an automatic thread reeling machine (not shown) with an interval of several n, and the thread is reeled. In some cases, when the thread traverses, the thread receiver of the small frame 30 often comes off the part 38 and falls into the gap on the side opposite to the ring 40, and winds around the cylinder body 42a of the adjacent small frame 30 and the grain part 32. Since the soft portion 32 is provided with the rib 54 whose outer edge rises inward as described above, the faint light that wraps around the rib 54 is directed toward the flange portion 50; rolled up.

Therefore, the thin light wrapped around the flange portion 50 can be cut off with a knife or the like, or it can be extracted from the end of the flange portion 50.

Even if the faint light does not completely move toward the flange portion 50 and wraps around the rib 54 slightly, the rib 54 is formed to have the same diameter as the flange portion 50 or a slightly larger diameter, so it cannot be cut or Extraction is easy.

In addition, in order to make it easier to cut the thin light wrapped around the flange part 50, the flange part 50 is cut as shown in FIG.
A grooved strip 60 may be provided on the top.

Furthermore, the ribs 54 may be made to extend from the end surface of the flange portion 50 onto the outer circumferential surface of the soft portion 32, instead of being made to stand up from above the soft portion 32.

In order to reduce the dim light, it is preferable to provide a ring 70 projecting slightly outward from the thread receiver section 38 at the end of the thread receiver section 38 on the side opposite to the ring 40, as shown in FIG.

As described above, in the present invention, since the thin light is wound on the flange part or on a rib having the same diameter or a large diameter as the flange part, the work of removing the thin light is extremely easy and the work efficiency is improved. Effective.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
