Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a double moquette trapier loom in which the weft supply device is fixed to the loom frame and is mounted facing the reed with the needle traveling position as the boundary. .

[Conventional technology]

As shown in FIG. 2, on the weft supply side of the front of a conventionally used double moketto trapier loom, from the selvedge to the outside, there are a temple 11, a temple support plate 12, a yarn end suction nozzle 31, a weft guider 20, A cutter 13, a weft locking bar 32, a yarn end suction nozzle 14, and a weft setter 15 are installed in sequence, and a cutter 3 for cutting edges 33 is installed directly behind the temple 11 to separate the edges 33 from the upper and lower fabric bodies.
4 is attached, and the yarn end suction nozzle 14,
Air is always sucked in from 31, and the weft 18 approaching it is sucked and held, and the weft locking bar 32, cutter 13, and weft setter 15 operate as follows.

First, when the weft 18 is pushed out by the reed and approaches the woven fabric 17, the weft thread locking bar 32 descends below the warp arrangement surface and waits,
7, it moves upwards above the warp arrangement surface and moves toward the fabric front side, and when the reed retreats, it pulls the weft 18 toward the yarn end suction nozzle side 14, 31 to prevent the weft 18 from retreating. When the reed is stopped and the reed has retreated, the weft 18 is passed through the yarn end suction nozzles 14 and 31.
The cutter 13 operates to apply tension to the weft thread 18 in the tensioned state, and the weft thread 18
Cut and separate from the edge of the ear.

When the reed is retreated, the weft setter 15 pushes up the weft 18 and sets it to the running position of the needle 19, and then the needle 19 runs to a new warp opening 22 and draws the weft 18.

The weft locking bar 32 descends below the warp arrangement surface while the needles 19 are traveling within the warp opening, and waits to lock the next weft 18 to be driven.

The weft guider 20 has a cutter 1 that opens up and down.
This is to ensure that the weft yarn is drawn between the knives of No. 3.

[Problem that the invention attempts to solve]

In the prior art, as described above, the cutter 13 operates in the retracted state of the reed before the needle 19 runs, but it prevents the vibration and loosening of the weft 18 caused by the thrusting action of the weft setter 15, which operates at the same time, and moves the weft 18 between the upper and lower knives. In order to securely cut the yarn by tensioning it straight between
2 are provided.

Therefore, the weft guider 20 and the weft locking bar 32
may be provided near the cutter 13 near the weft setter 15, but at least one of the two yarn end suction nozzles 31 must be provided between the temple 11 and the cutter 13.

As a result, the end of the cut weft yarn protrudes from the edge by at least an amount equivalent to the width of the suction nozzle 31.

Conventionally, the protruding ends of the weft yarns were woven so as to be held by the warp waste yarns 35, and then cut off directly behind the temples 11.

Therefore, the cutter 3 for the discarded ear is placed directly behind the temple 11 of the conventional double moketto trapier loom.
4 is provided.

The weft and warp yarns 35 corresponding to the width of the suction nozzle 31 and the width of the sacrificial selvedge 33, which constitute the sacrificial selvage 33, are the threads that are carried as loss yarns that inevitably occur due to the use of the double-moketsu rapier loom. Including the quantity, the weaving standard of moquette is designed.

However, such loss yarn is 5% of the amount of yarn to be carried
It accounts for ~7%, and this is a major bottleneck in reducing raw material costs.

[Purpose of invention]

Therefore, the present invention solves this problem and
It is an object of the present invention to provide a double moquette rapier loom that does not cause the loss due to No. 3.

[Structure of the idea]

The double mokette trapier loom according to the present invention has a temple 11 that tensions the selvage edges 16 of the fronts of the upper and lower fabrics to the left and right from the selvage edges on the weft supply side of the woven fabrics outward. , a temple support plate 12 parallel to the selvage 16 of the temple 11 that projects at a substantially right angle to the selvedge 16, a cutter (scissors) 13 for cutting off the weft from the woven fabric 17, and a yarn feeding device for the separated weft. Suction nozzle 14 that sucks and holds the following terminal
The weft yarn 1 continues from the suction nozzle 14 to the yarn feeding device.
8 to the weft catching position of the needle 19 and the weft setters 15 are arranged in sequence and attached to the frame side of the loom, and the reed in beating motion comes into contact with the loom 17. Alternatively, the timing of the cutter 13 is set so that the weft yarn 18 is cut when the weft yarn 18 substantially comes into contact with the weft yarn 18.

In the present invention, the weft guider 20 conventionally attached to a double moketto rapier loom is not necessarily necessary, but if the tips of the upper and lower knives of the cutter 13 are extended and opened wide and the weft is introduced between them, the weft guider 20 is not necessary. 20 may be omitted. In this way, the weft guider 20 can be attached to the left or right side of the cutter 13 as needed, but if it is to be attached near the cutter 13, it can be attached as shown in FIG. It is preferable that the front surface of the temple support plate 12 is made to protrude toward the reed side, and the protruding portion is used as the weft thread guider 20.

FIG. 1 depicts the weft supply section of the double moketto rapier loom constructed as described above from the reed side toward the fabric front 17, and shows the ground warp and pile warp 21.
is opened in two stages, upper and lower, and has two upper and lower needles 19,
19', the two upper and lower weft yarns 18, 18' are inserted into the upper and lower openings 22, 22', respectively.

In the figure, 23 and 23' are weft thread guides fixed to the frame, and are mounted close to the lower sides of the running needles 19 and 19', respectively.

There is a space between the cutter 13 and the suction nozzle 14 that is large enough to allow a vertical frame plate at the edge of the reed to be pushed into it. On the other hand, there is a space necessary for the weft guider 20 and the cutter 13 to fit between the reed feathers at the edge of the reed and the vertical frame plate. In this way, when the reed advances to the woven fabric 17 and is hit, the weft guider 20 and the cutter 13 are prevented from colliding with the reed, so that the weft yarns 18 and 18' are hit and hit above and below the cutter 13. At the same time as it is pushed between the knives, it is sucked and held by the suction nozzle 14.

Reference numeral 24 denotes a setter holding member which is hinged (pin) connected to a support member 25 fixed to the frame and swings up and down while supporting the weft setter 15, and is driven by a cam (not shown). In addition, cutter 13
The lower knife is similarly driven to swing up and down by a cam.

26 is a suction pipe that continues from the suction nozzle and is connected to a discharge fan (not shown).

[Effect of idea]

In the double moquette rapier loom according to the present invention, the cutter 13 is activated when the reed contacts or substantially contacts the loom 17 as described above.

However, at such a point, one end of the weft near the edge of the weft is held by the weft 17 and the other end is held by suction by the suction nozzle 14, and the reed feathers and the reed vertical frame plate are At this point, the weft setter 15 does not operate and the resulting vibrations are not applied to the weft 18. As a result, the weft yarns 18 near the selvage edge of the fabric are straightened.

According to the present invention, (1) the weft yarn 18 can be reliably cut without installing the suction nozzle 31 between the cutter 13 and the temple 11, which was required in the past, and the suction nozzle 31 is not required. The mechanism of the double moquette rapier loom is simplified and easy to handle.

(2) In this way, since the suction nozzle 31 is not required between the cutter 13 and the temple 11, the cutter 13 can be attached very close to the woven fabric selvage 16, and thereby the woven fabric selvedge 16 The loss of the weft yarn 18 protruding from the weft is eliminated.

(3) Therefore, there is no need for the discarded ear 33 to be cut and removed, and as a result, the discarded ear cutter 34, which was conventionally provided directly behind the temple 11, is also unnecessary.
In this respect as well, the mechanism of the double moquette rapier loom is simplified and easy to handle.

As described above, according to the present invention, there is no need for the discarded selvedge yarn, which conventionally accounted for 5 to 7% of the amount of yarn carried in a moquette, reducing raw material costs and making the double moquette trappier loom easier to handle. Become something.

Therefore, the present invention is extremely convenient for producing double moquettes economically and efficiently.
