Description

TECHNICAL FIELD [0001] The present invention relates to a detection sensor for a mesh web weaving machine using a water jet loom and a weaving method for a mesh web,

The present invention relates to a water jet loom, which can increase the productivity of a mesh paper and reduce a unit cost by making it possible to weave as a mesh paper under detection and control of weft yarns crossing between warp openings by an injection nozzle during weaving of a fabric through a water jet loom, The present invention relates to a detection sensor and a method for mesh fabrication.

A water jet loom is a kind of weaving loom that weaves a fabric. When a weft (weft) is fed in a direction perpendicular to the warp, a water jet loom is sprayed at a high pressure from the injection nozzle without using a shuttle. Is a sort of shuttle-less loom that weaves a fabric by passing it between openings.

The water jet loom has a high productivity because it is able to rotate at high speed because it transports the weft using high-pressure jet water. In addition to the productivity improvement 4 ~ 6 times as compared with the general shuttle loom, Since the noise is remarkably low when compared with the shuttle loom, it is widely used as a reason for productivity improvement and noise reduction.

Weaving in a water jet loom is divided into a shedding motion dividing the slope into upper and lower halves so as to form an opening through which the weft passes, and a picking motion for letting the weft through the opening formed by the above- And weaving is performed by a beating motion in which the weft passing through the opening is pushed up to the cloth as a reed to make the warp and weft forms a single structure.

In the weaving process, whether the weft yarn is supplied to the gap between the openings of the warp yarns is detected by the weft yarn belt mounted on the other side of the jet nozzle, So that the apparatus stops all operations of the loom.

Therefore, in the conventional water jet loom, the weft yarn is surely brought into the gap between the opened slopes by the injection nozzle for spraying the high-pressure jet, so that the weft yarn supply is controlled by controlling the operation of the weft loom System, which can be used as a loom producing only a plain weave fabric, and the range of use thereof is limited.

If water jet looms are systemized not only as weaving loom, but also as weaving looms capable of producing mesh fabrics, we can reduce the unit cost by simplifying the structure and reducing the cost compared to general shuttle looms that produce mesh fabrics. It is expected that it will improve the quality. Therefore, the development is urgently required.

Therefore, it is an object of the present invention to provide a water jet loom, in which when the weaving machine is used to switch on / off control of the detection sensor, a clear signal corresponding to the weft- The water jet loom can be woven in a water jet loom by using a water jet loom so as to improve the productivity while simplifying the structure of the water jet loom. Sensor, and a method of fabricating a mesh.

According to the above object, in a water jet loom, according to the above-mentioned object, in a water jet loom, detection of a weft yarn spouting through a first jetting nozzle (2) The sensor 10 is configured to act as a switch for the ON / OFF control operation. In this case, when the first injection nozzle 2 senses that the sensor 10 is in the ON state in response to the weft- The signal is sent to the main controller 30 so as to be operated normally and the second injection nozzle 4 injects only the number of injections without weft, and the sensor 10 is turned off, (2), (4), and the warp and weft of the weft yarn are operated by the opening and closing operation of the loom so that the stop operation signal of the warp yarn can not be detected by the main controller (30) (P) is formed by crossing alternately. Characterized in that the configuration.

In the present invention, the main sensor 30 senses an operation signal of the weft-sensing region 20 by operating the sensing sensor 10 in an on-state in response to an incoming signal of the weft through the first injection nozzle 2 (2), and the second sensor (10) detects the presence of the sensor (10). The second sensor (10) detects the presence of the sensor (10) So that the main control unit 30 can not detect the stop operation signal of the weft sensing unit 20 so that the weft yarn is woven in the weft without any weft under the normal operation so that the first injection nozzle 2 ) Of the second injection nozzle (4) and a warp yarn which is operated to open under repeated operation of the weft-free yarn of the second injection nozzle (4).

The present invention is characterized in that when a purifying signal due to the introduction of weft yarn through the first jetting nozzle is inputted, the detecting sensor is turned on and the weft-sensing globe and the main control unit are connected to each other so that the weaving machine operates normally and without the intention of weft through the second jetting nozzle When a publicity signal for spraying only the number of injections is received, the detection sense is turned off, and the stop signal of the weft-trapping earth is prevented from being detected by the main controller so that the loom is normally operated. As a result, the first and second injection nozzles alternate, And a water jet loom in accordance with the present invention.

In addition, the present invention has the advantage of lowering the unit price and improving the quality of the product by making it possible to weave the mesh fabric through the water jet loom so as to increase the productivity of the mesh paper at high rotation in comparison with the normal shuttle loom.

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

Generally, a water jet loom has a spray nozzle mounted on one side and a stomach with a stomach on the other side, passing through slopes where the weft is operated to open by the high-pressure jet of the spray nozzle, As the loom, at this time, the weft detecting section senses whether or not the weft supply is supplied according to the weft insertion, and when the weft supply is not properly performed, the detection signal is sent to the main controller to stop the operation of the loom.

Therefore, the existing water jet loom is controlled by the main control unit connected to the weft-sensing zone as a system to stop the operation of the loom unless the normal supply is provided according to the weft introduction. So that only plain weave fabrics are produced.

Therefore, the present invention is not only capable of detecting the weft signal of the weft yarn supplied by the jetting number of the jetting nozzle but also detecting the jetting signal of the jetting nozzle without supplying the weft yarn, The main controller can operate normally without stopping the loom so that the fabric of the mesh paper can be woven through the water jet loom.

1 is a circuit diagram of a sensing sensor according to an embodiment of the present invention. FIG. 2 is a block diagram of the present invention. FIG. 3 is a block diagram of a water jet loom of the present invention. Fig. 4 is a schematic view of a water jet loom. Fig.

As shown in FIG. 4, the water jet loom A according to the present invention includes two first injection nozzles 2 and a second injection nozzle 4 on one side so as to be cross- And the other end of the first and second injection nozzles 2 and 4 is provided so as to face the weft sensing jig 20 so as to detect whether the weft yarn is supplied through the weft sensing jig 20, Thereby allowing the connected main controller 30 to control the operation of the loom.

At this time, the main controller 30 controls the operation of the loom so as to detect the operation signals of the first injection nozzle 2 and the second injection nozzle 4 between the main controller 30 and the weft- The main controller 30 may be configured to be connected to each other through a sensing sensor 10 that senses a stop signal generated by the sensing sensor 10 so as to prevent the sensing sensor 10 from sensing the sensed sensor 10, Role.

The detection sensor 10 receiving the operation signals of the first injection nozzle 2 and the second injection nozzle 4 receives the operation signals of the first injection nozzle 2 and the second injection nozzle 4 as shown in the circuit configuration diagram of FIG. The sensor sensor 10 is connected to the supply signal of the first injection nozzle 2 so that the main controller 30 recognizes the sensing signal of the weft sensing strip 20, A normal operation of the weaving machine is performed under the detection of the weft-feeler 20 by the weft yarn injected through the first injection nozzle 2 and the detection sensor 10 is supplied with the supply signal of the second injection nozzle 4 The detection signal of the weft sensing unit 20 is turned off so as not to be perceived by the main controller 30 and the stop of the weft sensing unit 20 is stopped by the second injection nozzle 4, The loom is also configured to control the normal operation to be performed.

Therefore, the water jet loom A of the present invention is configured in such a manner that the detection sensor 10 is turned on in response to the false signal due to the weft insertion of the first injection nozzle 2 and the operation signal of the weft- The detection sensor 10 is turned off and the stop operation signal of the weft sensing unit 20 is transmitted to the main controller 2. In this case, The weft yarn is prevented from being detected by the weft yarn splicing device 30 so that the weft yarn is operated normally and the weft yarn is repeatedly ejected by the first jetting nozzle 2 and the second jetting nozzle 4, The weaving is performed as the mesh paper P by the intersection with the inclination according to FIG.

A weaving method according to the operation state at the time of weaving the net cloth P with the waterjet loom A configured as described above will be described below.

First, the sensing sensor 10, which has received the correcting signal according to the incoming of the weft by the high-pressure jetting water through the first injection nozzle 2, operates as an ON state, and transmits an operation signal of the weft- So that the weft yarns are woven into the gap between the opened yarns.

Thereafter, after the operation of the first injection nozzle 2, the detection sensor 10 operates in the OFF state with respect to the all-purpose signal spraying only the number of injections through the second injection nozzle 4 without weft, The main control unit 30 blocks the stop operation signal so that the loom is operated in a state in which the loom is weaved while moving only the warp without weft under normal operation.

Therefore, mesh cloth P is woven in accordance with the intersection with the slope of the opening of the first injection nozzle 2 under the repetitive operation of the weft-free hollow of the second injection nozzle 4.

When a purifying signal due to the weft insertion is input through the first injection nozzle 2, the weft sensing unit 20 and the main controller 30 are connected to each other so that the weaving machine operates normally When a publicity signal for injecting only the number of injections is input without intrusion of the weft through the second injection nozzle 4, the detection sense 10 is turned off to block the stop signal of the weft sensing unit 20 from being detected by the main controller, The first and second injection nozzles 2 and 4 alternate with each other, and the woven fabric of the net pile fabric P is formed through the water jet loom A by the operation of the weaving and weaving of the weft yarns .

In addition, the present invention is advantageous in that it is possible to weave the mesh fabric through the water jet loom (A), thereby increasing the productivity of the mesh fabric at a high rotation in comparison with the normal shuttle loom, while lowering the unit price and improving the quality of the product .
