Description

A kind of capture gripping of weft yarn tail and detection device

Technical field

The utility model belongs to capture gripping and the detection device of textile technology field more particularly to a kind of weft yarn tail.

Background technology

Air-jet loom is the shuttleless loom that shed open is passed through using jet-stream wind weft traction.Operation principle is made using air For wefting insertion medium, frictional traction is generated to weft yarn with the compressed air stream ejected and is drawn, weft tapes are crossed into shed open, are passed through The jet stream that jet generates achievees the purpose that wefting insertion.This filling insertion way can make loom realize high speed high yield.In the prior art, it dredges Weft fabric is manufactured usually using air-jet loom, as shown in Figure 1, the slay 2 of air-jet loom is around the front and back pendulum of slay rocker center line 1 It is dynamic, profiled steel reed 3 is housed, the weft insertion system timing of air-jet loom is by weft yarn from left side along the air drain of profiled steel reed 3 on slay 2 It is directed to right side.It dredges weft fabric and requires weft yarn tail end fixed length and concordant, to carry out program-controlled invagination for air-flowing type tucker, formed Plain edge.But the right end that weft yarn is led to profiled steel reed 3 in weft insertion system along air drain, when going out reed, weft yarn tail 4 is to be in sky In wave in the wind and beat bent state, be difficult to realize the timing cut-to-length of scissors 5.

Utility model content

For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of capture of weft yarn tail hold and Detection device, it is simple in structure, stable, it captures weft yarn tail and holds, it is made to be positioned into the sheared edge of scissors, it is fixed to realize When cut-to-length, reach thin weft fabric to the requirement of the size of weft yarn tail.

To achieve the above object, the present invention adopts the following technical scheme that：

A kind of capture gripping of weft yarn tail and detection device, including slay, profiled steel reed, scissors and PLC controller, it is special Point is that gripping seat is set on the slay, and needle core base, the needle core base and the same center of profiled steel reed reed slot, institute are set on the gripping seat It includes negative pressure end and end of probe to state needle core base, and the negative pressure end sets air inlet on the right side of scissors on negative pressure end, the air inlet with Slotting gas connector and the gas circuit with solenoid valve are sequentially connected soon；Negative pressure end inner cavity is truncated cone-shaped, if negative pressure needle core is leaned on internal chamber wall It connects；The end of probe sets detection window, and the slay sets thread monitor, the thread monitor with detection window corresponding position Detection eye be aligned detection window；The solenoid valve, thread monitor and PLC controller are electrically connected.

Further, the negative pressure needle core is bipyramid bell shape, extend into needle core base inner cavity and is more than air inlet position It sets, setpoint distance is reserved with negative pressure end internal chamber wall.

Further, the negative pressure end of the negative pressure needle core and needle core base is equipped with trimmer, adjusts negative pressure needle core and negative pressure end Internal chamber wall distance, and then wanting to make negative pressure end pressure to maximum compared with little airflow condition.

Further, the tube socket of defeated yarn nylon tube and fixed defeated yarn nylon tube, tube socket are also associated on the right side of the end of probe It is located on slay, transition receiver is set on the right side of defeated yarn nylon tube, defeated yarn nylon tube right end stretches into transition receiver, and transition receives Collecting box is set on the right side of device.

It is located on slay in use, holding seat, the same center of reed slot of needle core base and profiled steel reed.It is equipped with for one section in needle core base The negative pressure needle core of negative pressure can be formed and adjust the trimmer of vacuum magnitude, the gas circuit that can connect provided with electromagnetic valve is rotary on needle core base Slotting gas connector soon, when weft yarn is sent to profiled steel reed right end by weft insertion system, PLC controller controls electromagnetism valve action timing and opens Gas circuit, compressed air enter in the special space that needle core base and negative pressure needle core are constituted, and are produced at the bipyramid horn mouth of negative pressure needle core Raw adsorption capacity, makes weft yarn tail favorable current first be drawn to the right along the axle center of needle core base and stretches, and reach needle detection window；Detecting window Thread monitor at mouthful illustrates that the wefting insertion is effective, not detecting explanation, this draws by detecting eye detection when detecting weft yarn tail Latitude it is invalid or it is partially short fall short of, PLC controller instruction stop；Above-mentioned weft yarn tail is captured after gripping and swings to it with sley system When special angle, the timing of scissors that weft yarn tail is waited for and cut-to-length hand to tucker；Remaining tack rag is pressed from both sides in tube socket It conveys to the right, is transported in collecting box through transition receiver, at this time the gas of quick connector with air-flow in tight defeated yarn nylon tube Way solenoid valve timing is closed.

Compared with prior art, the utility model has the advantages that：It is simple in structure, it is easy for installation, latitude is realized by the device Yarn captures the multiple function that gripping → finding lost pick → timing cut-to-length → tack rag is sent to collecting box from wefting insertion → weft yarn, real The timing cut-to-length for having showed weft yarn tail, the air-flow invagination to dredge weft fabric provide technology and ensure.
