Abstract
The invention relates to a method for improving the feeding behavior of a weft yarn, especially a weft yarn made of synthetic filaments, during the production of fabrics on jet looms, particularly pneumatic jet looms. The aim of the inventive method is to limit the modification of the weft yarn, especially regarding a damaging change in the weft yarn structure, which results from a previously known intermingling process in the mixing tube of a main blow nozzle, to a length that will ultimately be part of the wasted weft yarn while dispensing with the holding process of the weft yarn by means of holding air. Said aim is achieved by the fact that the weft yarn (7) that remains in the main blow nozzle (1) is clamped by a clamping device (6) downstream of the injector (2) of the main blow nozzle (1) in the feeding direction (15) of the weft while the length of the weft yarn (7), which is introduced into the warp shed, is tied by closing the warp shed, whereupon the weft yarn (7) is subjected to an intermingling process along the length that remains between the clamping device (6) and the tie located at the feeding end as long as the angle of rotation of the main shaft of the loom lies within a predetermined range.
Description
The present invention relates to as the described a kind of method of when particularly on air-jet loom, producing fabric on the jet loom, improving the wefting insertion characteristic of the weft yarn that weft yarn particularly made by synthetic thread of the feature of claim 1 preamble.
The invention still further relates to particularly air-jet loom of a kind of jet loom of implementing the above-mentioned weft yarn Weft insertion method that is subjected to pattern control.
A kind of defending party to the application as open source literature use be used for interleave do not have interleave or only the method for the weft yarn particularly made by synthetic thread of the weft yarn of part interleave and a kind of loom of implementing this method are that application number is the content of 10,209 278.8 German patent application.
Content according to above-mentioned patent application, one of weft yarn longitudinal component that extends from porch to the exit of the mixing tube of main burner of main burner is at its end regions, promptly implements interleave process (T ngelvorgang) in the exit near the mixing tube of main jet pipe.This measure cause weft yarn until the injector interior of main burner and partly until pre-bobbin winder (Vorspuler) more or less by mistake by interleave.Partly again that described interleave body is loose by the so-called maintenance air that must in the time that weft yarn pauses, in the zone of main burner, aim at weft yarn.
Overlapping (with keeping air to keep weft yarn and carrying out interleave with air-flow) of described process particularly causes the leaching (Herausl sen) and the fracture of long filament on the one hand in the zone of the yarn of easy fracture.
On the other hand, the weft yarn structure has been changed on certain-length by keeping air and interleave process, becomes the fabric composition part after the weft yarn structure on this length is being introduced weft yarn.The quality of made thus fabric has been damaged to a great extent.
Task of the present invention is the change of the weft yarn that is caused by one in the mixing tube of main burner known interleave process when improving the wefting insertion characteristic of weft yarn under above-mentioned background, particularly consider change to the damageability of weft yarn structure, be limited on one section weft length that became the weft yarn waste material afterwards, and abandoned utilizing the maintenance process that keeps air that weft yarn is implemented.
The method according to this invention realizes basically like this, promptly, the weft length that rests in the main burner after weft yarn is introduced a shed open is clamped by a clamping device on a position after the injector at main burner on the weft yarn wefting insertion direction, so the weft length of described introducing shed open is tightened by closing closing the shed, and weft yarn rests on clamping device and introduces tightening on the length between the place of side and implement the interleave process in the predetermined rotational angular range at loom main shaft at it.
Thereby obtain such advantage, that is, for one the weft yarn interleave body of interleave be held air no longer again and dispel, thereby thereby can abandon keeping air up hill and dale and reduce the compressed-air actuated energy that uses and saved.
Avoided the shortcoming brought by known solution in addition.
In the design according to the inventive method, described interleave process also promptly was approximately 320 at the rotational angle of loom main shaft and comes into effect when spending before cutting off the weft yarn of being introduced from ready weft yarn.
It should be noted that in addition the interleave process occurs in the interleave pipe of main burner as known when using this method.
The method according to this invention is implemented in one to be had on the jet loom that the weft yarn that is subjected to pattern control introduces, particularly on the air-jet loom.
According to claim 6, described air-jet loom comprises at least one main burner, and it has injector and mixing tube; A clamping device that is used for clamping weft yarn, it is being arranged on weft yarn wefting insertion direction after the injector within the mixing tube; An interleave device is it is arranged on clamping device on the wefting insertion direction after and within the mixing tube or be arranged on the mixing tube outlet side; And be used for forming a shed open and cause the device of shed closed.
Clamping device in mixing tube that is arranged on main burner especially can be the center blocking device of the breathing member (Muskel) of a pneumatic or hydraulic pressure according to the present invention.
In addition, clamping device can be breathing member and two members as clamping element that are integrated in the sheet in the breathing member of a pneumatic or hydraulic pressure, the member that it is made by the spring material and constitute clamping device with the breathing member.
In addition, two flat members of being made by preferred spring material can be set, wherein can adjust a flat member at least two flat members with respect to the position of another one flat member by controllable device as clamping device.At least one flat member can be designed to piezoelectric element, and perhaps at least one flat member can be equipped with the calutron that can switch on.In other design of the present invention, above-mentioned clamping device is surrounded by a cavity of a shell, and this shell is arranged between first mixing tube part and the second interleave tube portion of mixing tube.
In the interleave device, relate to an applicant used device in the past, for the described mixing tube of interleave has that extend transverse to weft yarn wefting insertion direction, as to feed the inner chamber of a mixing tube interleave hole at least, it is connected on the pneumatic pressure source by at least one controllable electromagnetic valve in this device.
The present invention is described in detail by means of an embodiment below.
Accompanying drawing shows a main burner 1, its have after the injector that is arranged on main burner 12, at first mixing tube part 4 of mixing tube 3 and the clamping device that is used for weft yarn 76 between the second mixing tube part 5.
Clamping device 6 is configured to a pneumatic breathing member 8 at this.But described pneumatic breathing member 8 is surrounded by the cavity 9 of a pressure-loaded of a shell 10.
But electromagnetic direction valve 11 and pressure piping 12,13 compressed air by an electric control are transported to the cavity 9 from pneumatic pressure source 14.Breathing member 8 is tightened weft yarn greatly mixing tube 3 on the longitudinal central axis line.
Clipped weft yarn 7 is through one section preset time.Make breathing member 8 unclamp by electromagnetic direction valve 11 is switched to on-position B from on-position A, thereby weft yarn 7 is introduced in the unshowned shed open along the direction shown in the arrow 15.
A known interleave device 16 is set on the second mixing tube part 5 after clamping device 6.
Described interleave device 16 has a compressed air interface 17 transverse to mixing tube 3 longitudinal central axis lines, and it feeds the transverse holes 18 of mixing tube part 5.The electromagnetic direction valve 19 of an electric control couples together interleave device 16 and a pneumatic pressure source 22 by pressure piping 20,21.By electromagnetic direction valve 19 is switched to on-position B from on-position A the interleave process is interrupted.
