Description
Technical field
The present invention relates to a kind of weft inserting apparatus for jet type loom.
Background technology
The weft inserting apparatus of jet type loom possesses to the main burner that carries out wefting insertion supplies with compressed-air actuated compressed air feedway.Compressed-air actuated feedway has to control provides compressed-air actuated open and close valve to main burner, and open and close valve is connected by catheter pressure with main burner.
Open and close valve is fixed on fixed position, for example is fixed on the first-class for the yarn body side frame of loom, on the other hand, main burner is fixed on the slay of swing, together swing with reed, therefore described catheter pressure employing has flexible, and its length is the nylon hose of allowing the degree of slay swing.
For example, the weft inserting apparatus of the jet type loom in patent documentation 1, with the mode stationary arrangement of the open and close valve of compressed air feedway with the encirclement main burner, each open and close valve is connected by having flexible catheter pressure with main burner, the pipeline of each catheter pressure all is made as essentially identical shortest path, and is jet rapidly with realization response.
In addition, existence can, according to the variation of the fabric width of weaving cotton cloth of weaving, be moved the jet type loom of adjusting with the installation site of main burner to the fabric width direction of weaving cotton cloth.
When the fabric width of weaving cotton cloth is changed, should take which position on the fabric width direction of weaving cotton cloth as benchmark, the various looms of this point are different, wherein there is a kind of method to be: take the center line of the maximum fabric width of weaving cotton cloth on loom as benchmark, distribute the left and right end position of the fabric width of weaving cotton cloth with respect to center line, namely according to so-called " center reference ", the fabric width of weaving cotton cloth is changed.
For example, need the left right balanced jacquard weaving machine of messenger wire and need warp beam and the left right balanced double ends shaft type loom of warp tension etc. has just adopted above-mentioned " center reference ",, according to the fabric width of weaving cotton cloth of weaving, according to center reference, adjusting is moved to the fabric width direction of weaving cotton cloth in the installation site of main burner.
In the jet type loom of adjusting can being moved to the fabric width direction of weaving cotton cloth in the installation site of main burner, due to except allowing that slay swings, also need to allow the movement of main burner on the fabric width direction of weaving cotton cloth, therefore adopted the long conduit of body to be used as connecting the catheter pressure of open and close valve and main burner.
But, if adopt so long catheter pressure, when to approaching open and close valve one side shifting that is positioned on the fabric width direction of weaving cotton cloth, regulating main burner, the distance between main burner and open and close valve can shorten thereupon, corresponding therewith, the deflection that connects the catheter pressure of main burner and open and close valve can increase thereupon.
And when the deflection of catheter pressure increased, the amplitude of the catheter pressure that causes due to the swing of slay will increase thereupon.Its result makes catheter pressure and peripheral device produce interference, accelerates friction consumption and the wearing and tearing of catheter pressure.
In addition, when the Distance Shortened between main burner and open and close valve, the catheter pressure overbending surpasses its minimum bending radius between main burner and open and close valve, and causes conduit to fracture, and is an impediment to compressed air is supplied to main burner.
For this problem, can consider following technical scheme: the installation site of open and close valve is made as and can moves adjusting to the fabric width direction of weaving cotton cloth, regulate main burner by movement, correspondingly the installation site of open and close valve is also regulated, thereby needn't use long catheter pressure also can tackle, main burner is regulated to the mobile of the fabric width direction of weaving cotton cloth.
But even open and close valve is made as and can moves adjusting to the fabric width direction of weaving cotton cloth, owing to there being various peripheral devices (for example selvedge shedding motion) on its mobile route, so the adjustable range of open and close valve installation site will be restricted.At this moment, at the amount of movement of fabric width direction of weaving cotton cloth, the adjustable range of open and close valve installation site can be dwindled with respect to main burner, so result still has to adopt long catheter pressure.
Especially as described in Patent Document 1 shown in technology, arranged in the weft inserting apparatus of open and close valve of compressed air feedway in the mode to surround main burner, because the space that open and close valve is occupied is larger, so the adjustable range of the installation site of open and close valve will be restricted.
