Description

DETAILED DESCRIPTION OF THE INVENTION This button is used to store the weft supplied from the weft supply section, and to store the measured weft once.
This relates to a weft sub-length device in a fluid injection type loom, which pulls out the stored weft during weaving.

Generally, in a fluid injection type loom, a 7ζth weft sub-length device is provided which pre-lengthens the weft to the length of one insertion and temporarily stores the measured weft. As a weft vice-length device for this yuzu, weft kunbe 〃Sara Itohoma (j
The weft yarn is wound around the tram, and the weft is wound around the tram and the weft is wound around the tram. A weft sub-length device has been proposed in which the weft yarns are stored and the stored weft yarns are pulled out during winding.

The weft 21 (lI wefting device 11 is 1 - ram circumference + 1TJ 7J) of this winding 4-size method is picked up by a pair of weft locking bins by a pair of weft locking bins. VC is set so that 11ilJ 11111 of -\ can be written.

Now, in a vice-length device in which the weft is fed by cutting through the base end of the winding arm that rotates around the drum, the weft thread is wound around the drum, and the arm rotates around the drum. ++

゛ The publication Hya also supports the same support 1i11I VCij,
! There is a lack of support for J. Hossegawa. When the drum that collects the weft rotates, the weft vice-length becomes a VC.7
The drum must remain still.

Conventionally, the method of placing the drum stopper was to have the rotor and planetary gear mechanism mounted integrally with the support shaft.
Or one that uses a magnet.However, all of these devices lead to the resulfurization of the structure, or lack of PI (:lγ), which is a factor in rice 1-up.

It's 7C.

This machine is different from the weft sub-length device of a trap follower, which uses a planetary gear mechanism or a magnetic sound to wind the thread (to keep the sea thread measuring part that forms the U thread stationary/). 1 (I) Bobbin bobbin ("J") can actually hold,
[There is no need to use different equipment sounds such as planetary gears or magnets, and therefore the structure can be used with a volume rate of VC72, which can reduce costs and eliminate weft insertion mistakes. It is an object of the present invention to provide a weft length measuring device for an mt body jetting type machine.

Hereinafter, we will embody the present invention and show all 7ζ-Examples in Figures 1.2 and 5.8. A support arm is fixed to the J part of the bracket 1, and has a hanging arm 3a facing the bracket 1. 4 is a support arm fixed to the J: part of the bracket 1. The weft guide hole 4a, which guides the weft Y2 supplied from the weft thread holder (not shown) such as a nurse, is arranged along its axis VC. 5 is a toothed pulley with a 4VCm cloth, and 6 is a toothed pulley with a 4VCm cloth, and 6 is a 5Kin pulley equipped with a 1t timing held.

7 is a rotary support 11qII located on the front side of the support bracket 1 (stone side in Figure 1);
8 intersects with the corridor support shaft 4 and is bent by a winding arm supported by the same pattern body T, so that the base end thereof is placed on the first tapered circumferential recess 108 of the drum 1u, which will be described later. A shape is inserted into the inside of the groove, and a 1ζ weft internal weir passage 8a is communicated with a 11'' wiring yarn guide hole 4a. 9 supports 1Jllll
It is a bracket which is mown to I4 and is located on the front side of the support body 7 and attached to the rotary rotor, and the drum 1u as the weft sub-length body was moved relative to the support ill+4 in the previous time. 711 rotatable and 8 fixed in 1l11 directions\8 immovably.

Reference numeral 11 denotes a first weft sub-length weft which is located on the circumference 11i11Ua of the drum 1u and extends in the radial direction of the drum 1u.

4. They are arranged approximately radially in the center of the frame, and are adjustable in position in the radial direction of the drum 1u. The valley rod 13 is formed with a substantially circumferential line winding 11uk together with the drum 10, and corresponds to a first inclined portion 13a centered on the first tapered circumference 10a of the drum 10 and a second tapered circumferential surface 1u1. The base 9 curved part 14 is fossilized on the upper part of the support arm 3,
The distal end is 11. The dispensing bin regulating member is placed one inch above.The weft retaining bin 11. A single-cut regulation hole 14n, 1413 is provided.

By the way, lj! J I like myself, 174 years ago, 1 piece, 1 piece, (.

Now, as shown in FIG. : Rotation support III when inserted
In II4, the drum 10 supported by the Aigarikai 1 Fukawa No. 1 is restricted from moving in the circumferential direction. Therefore, in this state I, the timing heddle 6 is driven 11 times with the weaving movement 1', and even if the rotary support shaft 4 rotates, the drum 10 is held stationary. As a result, the arm 8 rotates around the drum 1u in the static pressure state 1, and the weft guide hole 4a, the weft guide passage 8a and the opening 8b are moved from the yarn supply section to the weft guide hole 4a, the weft guide passage 8a and the opening 8b.
The weft yarn Y fed through the weft yarn is wound onto the first taper circumference 1υa and the first inclined portion 13a while being held by the first locking pin 11 in a protruding state.

While the first locking bin 11 is fitted into the regulation hole 14BK, the second locking bin 12 protrudes and is fitted into the regulation hole 14bvC, and as shown in FIG.
J7J'' and the like, the first locking bin 11?

And pruning to the second slope part 131J. Then, the weft Y pruned to the second taper circumference IJIIIOIJ and the second inclined portion 131) is locked by the second locking pin 12 fitted into the regulation hole 14b h, and the second taper circumference 1υ1) and second inclined portion 131] and is once wound and stored. During this time, the weft Y, which is fed to the rotary receiver MIp184 and is supplied through the entire reeling arm 8, is fed to the drum IUf.
The programming 10 is held in a static pressure state by the engagement state VCX between the second locking bottle 12 and the regulating hole 141J.

Seven Shun, while the second locking pin 12 is inserted into the regulation hole 14b, the first locking pin 11 protrudes and is inserted into the restriction hole 14n, and the first locking pin 11 is inserted into the restriction hole 14n (Fig. When the VC1 second locking bin 12 or the tram 1o71- is dead, the windings A and Y in which the flute accumulator 1 is pulled out are pulled out from the drum IUy+>, and the grout is inserted.

In addition, in this embodiment, there is a device VC in which at least one of the 12 retaining bins reaches its maximum protrusion;
As shown in the figure, if either one of the locking pins is always fitted into the regulating hole, the drum 1u is held in a stationary state.

Also, when the weft Y is locked in the locking pins 11.12, the locking pins 11.12 are inserted into the regulating holes 14a and 14b by one angle, so that the weft Y is locked in the locking pins 11 and 12. ) is out! L: No problem. At that point, the weft Y is at its original point of start of inserting J: ! l is also drawn out earlier (generally, the l!J￥peripheral start period of the jet fluid from the king nosuru (not shown) is set earlier to the right than the original gating start rib. Therefore, there is no fear that the weft or warp threads are not sufficiently open, or that the light will be attracted to the threads.

In addition, in this implementation 1 taro, the drum 10 is still used, and the conventionally used 3Ili Seiji, 11 machines 4h, both 1 and 7 parts lI-#llyo device.
