The present invention relates to a kind of Welf holder of loom.
As the glass fabric, when knitting the little fabric of system weft count with shuttleless looms such as jet looms, the tissue of just having knitted system gets loose easily.Therefore, open flat (Japanese Utility ModelApplication Laid-open.NO.) 1-119080 communique strictly according to the facts, Te Kaiping (JapanesePatent Application Laid-open NO.) 2-118141 communique is announced, form cloth distolateral on the limit of cloth end can't help the limit yarn, need control near the end of the weft yarn the fell.Opening in the flat 1-119080 communique real, disclosing on be used to cut off the fixing cutter of weft yarn and carefully between the spring (wire spring), the device of controlling the end of weft yarn.Open in the flat 2-118141 communique the spy, disclose the device of controlling weft yarn with pneumatic class dish.
But in the device of opening flat 1-119080 communique record in fact, the fabric of knitting system can move.And because the end of weft yarn is subjected to the effect of controlling of the thin spring and the fixing cutter of fixed configurations, so being subjected to this weft yarn of controlling effect can be by to the direction opposite with the moving direction of fabric drawing consumingly.Near this tissue reciprocal drawing effect meeting makes fell breaks, broken piece.
Open in the device of flat 2-118141 communique record the spy, pneumatic chuck is controlled the weft yarn end, carry out in the position of leaving fell as far as possible.When using pneumatic chuck device and control near the end of the weft yarn the fell, pneumatic chuck is held in the handle of weft yarn end in the stopping of input operation of fabric and carries out.Therefore, can not produce the real problem that device produced of holding flat 1-119080 communique record.But such handle sturcture only is applicable to the loom of the input mechanism of weaving cotton cloth with input of intermittently carrying out fabric.
Above-mentioned reality be can avoid and flat 1-119080 communique and the special existing design of Welf holder of opening the problem that device produced of flat 2-118141 communique record opened.The structure of this Welf holder is: at least one of a pair of holding body of controlling the weft yarn end used as the mobile and rotating revolving body along with fabric, makes the end of the weft yarn of controlling utilize the revolution of revolving body to carry towards the moving direction of fabric energetically.In this Welf holder, obtain the rotary driving force of revolving body by (beating) device that beats up.Promptly support back and forth the shaking of slay (sley) of reed (reed) to be communicated to revolving body through one-way clutch.Therefore, this revolving body is only to the single direction intermittent-rotation.
On the other hand, when taking place to fail the latitude mistake, must from fabric, remove the wrong yarn silk of defeated latitude mistake.Therefore, loom be overturn, separate out from following wrong silk of the effect of controlling of warp thread.
But, through above-mentioned one-way clutch, the reciprocal swing movement of slay is communicated in the Welf holder of structure of revolving body, can not make the revolving body counter-rotating.Therefore, be difficult to and will the wrong yarn that be held between revolving body and another holding body be removed from the fell of fabric.Especially at the weft processing equipment that is used for removing automatically, handling wrong yarn, be difficult to remove the wrong silk of controlling between revolving body and another holding body.
Therefore, the objective of the invention is to,, provide a kind of Welf holder that can remove the wrong yarn of defeated latitude mistake in order to address the above problem a little.
So, the present invention is an object with the Welf holder of following loom, this Welf holder the time makes the clamping rotor of the end of controlling near the weft yarn the fell of weaving cotton cloth close described translational speed revolution of weaving cotton cloth in the system of knitting, and the revolution that utilizes described clamping rotor is sent the end of the weft yarn of controlling between described clamping rotor and the other holding body to described moving direction of weaving cotton cloth.And, according to main aspect of the present invention, constitute following Welf holder, this Welf holder has with so that described clamping rotor is closing that the described system of knitting of weaving cotton cloth moves the positive rotary driving device just changeing and with so that the inversion driving device that described clamping rotor reverses.
Positive rotary driving device just changes clamping rotor, and like this, the system of knitting that clamping rotor is being closed weave cotton cloth moves and just changes.The end of the weft yarn that clamping rotor and another holding body are controlled is sent to the moving direction of weaving cotton cloth.And when taking place to fail the latitude mistake, the inversion driving device makes the clamping rotor counter-rotating.Therefore, the wrong yarn of controlling between described clamping rotor and described another holding body is just return direction and is carried to weaving cotton cloth, the result, and wrong yarn is just freed down from the effect of controlling of clamping rotor and another holding body.
According to a further aspect in the invention, at least one of described positive rotary driving device and inversion driving device wanted the double as treating apparatus of weaving cotton cloth.When constituting this by positive rotary driving device or inversion driving device and weave cotton cloth treating apparatus, the whole structure of device will become simple.
According to another aspect of the invention, described positive rotary driving device and described inversion driving device are made of the press roller that constitutes the draw-gear of weaving cotton cloth together with licker-in roller.
The peripheral speed of the press roller of weaving cotton cloth with licker-in roller association moving traction be the translational speed of weaving cotton cloth, with the peripheral speed rotating press roller identical with the translational speed of weaving cotton cloth as usefulness so that rotating positive rotary driving device of clamping rotor and inversion driving device are suitable.

Embodiment 1:
The present invention is embodied as the 1st embodiment of jet loom below with reference to Fig. 1 and Fig. 2 explanation.
As shown in Figure 2, slay 11 is provided with defeated latitude main burner 12, and weft yarn Y utilizes defeated latitude to penetrate in the opening of warp thread T with the jet action of main burner 12.Erectly be provided with distortion reed 14 on the slay 11.The weft yarn Y that penetrates in the opening of warp thread T utilizes a plurality of defeated latitudes to spray with the replacement of pilot jet 13 (only showing 1 among the figure), flies away in the defeated latitude path 141 of distortion reed 14 fronts.Be provided with defeated latitude prevention nozzle 15 at defeated latitude with below the injection pathway of main burner 12 tight.Defeated latitude stops the injection direction and the defeated latitude of nozzle 15 to be reported to the leadship after accomplishing a task with the injection pathway of main burner 12.Defeated latitude stops nozzle 15 all to be connected on the compressed air supply source (do not have among the figure and show) via electromagnetic opening and closing valve 16,17,18 with main burner 12, defeated latitude with pilot jet 13 and defeated latitude.Electromagnetic opening and closing valve 16,17,18 is accepted the demagnetization of encouraging of loom control computer C and is controlled (energisation-deenergisationcoutrol).
As shown in Figure 1, slay 11 is being supported by axis of rocking 21 through lay sword 20.Axis of rocking 21 obtains driving force and back and forth reverses through reciprocating drive mechanism from loom drive motors M.Slay 11 utilizes the beating motion that back and forth reverses and back and forth shake of axis of rocking 11.Loom drive motors M is by loom control computer C control.
At defeated latitude end side, be provided with weft detector 19.When carrying out normally failing latitude, the front end of weft yarn Y arrives the surveyed area of weft detector 19.Like this, when defeated latitude normally carried out, loom control computer C made electromagnetic cutting knife 22 cut off action after beating up.The weft yarn Y that the fell W1 that is made at the W that weaves cotton cloth by the effect of distortion reed 14 is subjected to yarning is cut off by the cut-out action of electromagnetic cutting knife 22.Loom control computer C detects information, the angle of revolution of learning loom according to detected the angle that obtains with rotary encoder 39 by the weaving machine turning angle.When weft detector 19 did not detect weft yarn in the specified time limit in the loom rev, it is unusual that loom control computer C just is judged as defeated latitude, stops electromagnetic valve 16,17, and the strict demagnetization control of electromagnetic cutting knife 22, simultaneously, stops the action of loom drive motors M.
Loom W utilizes association's trend expansion sley bar 26 sides input of licker-in roller 23 and a pair of press roller 24,25.Licker-in roller 23 obtains power from loom drive motors M.Press roller 24,25 Jie that the W that weaves cotton cloth is pressed to the side face of licker-in roller 23 are being supported by bar 27,28 by roll shaft 241,251.This bar 27,28 can supported by fulcrum 29,30 with reversing.Break-through is provided with adjustment screw 31,32 on the bar 27,28.Be lined with compression spring 33,34 between the head of screw of bar 27,28 and adjustment screw 31,32. Adjustment screw 31,32 is twisted solid at fixed part 35, puts by the stubborn maintenance of regulating adjustment screw 31,32, regulates the plus-pressure of 24,25 pairs of licker-in rollers 23 of press roller.Therefore, when adjustment screw 31,32 was unscrewed, press roller 24,25 left from licker-in roller 23 shown in Fig. 1 dotted line.
Driving rotational body 36 ends admittedly on the roll shaft 241 of the press roller 24 of a side.And driven revolving body 37 is supported on the fulcrum 29 pivotally.The side face of driven revolving body 37 is exerted pressure and contact with it to the side face of driving rotational body 36, is accompanied by the revolution of press roller 24, and driven revolving body 37 is along the direction revolution opposite with press roller 24.The driving Timing Belt wheel 40 that plays the effect of drive transmitting body is supported on the fulcrum 29 pivotally.Drive Timing Belt wheel 40 and driven revolving body 37 and be combined as a whole, driving Timing Belt wheel 40 and driven revolving body 37 can be to the either direction revolution with respect to fulcrum 29.
As shown in Figure 2, be fixed with driven timing pulley 42 propping up pivotally on the fulcrum 41 that is held on the support 38.Be contained in driven timing pulley 42 and drive Timing Belt wheel 40 on both as the Timing Belt 43 of thread like body.Be fixed with on one end of fulcrum 41 and control revolution basis 44.The elastic ring 441 of rubber system is embedded on the side face of clamping rotor 44.The tight below of clamping rotor 44 is equipped with stationary clamping body 45.The upper side contact of solid holding body 45 is on the side face of elastic ring 441.The weft yarn Y that is beaten up is cut off by electromagnetic cutting knife 22, utilizes moving to the zone of controlling of clamping rotor 44 and stationary clamping body 45 of the W that weaves cotton cloth to import simultaneously.Then, the end Y1 of weft yarn is being held between clamping rotor 44 and the stationary clamping body 45.The end Y1 of the weft yarn of controlling between clamping rotor 44 and the stationary clamping body 45 utilizes the revolution of clamping rotor 44 to be carried by the moving direction to the W that weaves cotton cloth.
Knit when system, the just commentaries on classics of the input direction of weaving cotton cloth of licker-in roller 23 through press roller 24, driving rotational body 36, driven revolving body 37, drive Timing Belt wheel 40, Timing Belt 43, driven timing pulley 42, and fulcrum 41 transmit to clamping rotor 44.Utilize this revolution to transmit, clamping rotor 44 turns round to the direction shown in Fig. 1 arrow R.When the loom counter-rotating was loom drive motors M counter-rotating, licker-in roller 23 was to turning round with the input direction opposite direction of weaving cotton cloth.Under this backspace commentaries on classics state, clamping rotor 44 is to turning round with arrow R opposite direction.That is, press roller 24 becomes the inversion driving device that makes the positive rotary driving device that clamping rotor 44 just changeing and make clamping rotor 44 counter-rotatings.And driving rotational body 36, driven revolving body 37, driving Timing Belt wheel 40, Timing Belt 43 and driven timing pulley 42 become the driving force transfer device with positive and reverse steering clamping rotor 44 transmission of press roller 24.
When taking place to fail the latitude mistake, loom control computer C stops the action of loom drive motors M, simultaneously, makes electromagnetic valve 18 excitations, makes defeated latitude group end nozzle 15 and sprays.The jet action that defeated latitude group is ended nozzle 15 makes the follow-up weft yarn Ye of the wrong yarn Ym of defeated latitude mistake be positioned at position away from the cut-out zone of electromagnetic cutting knife 22.The wrong yarn Ym fell W1 that beaten up.Loom carries out stopping before the beating up of back after 14 couples of wrong yarn Ym of distortion reed beat up.
Then, loom control computer C makes the loom drive motors M ormal weight that reverses lentamente.Like this, the opening of the warp thread T fell W1 that becomes the W that can weave cotton cloth certainly removes the opening of the maximum of wrong yarn Ym.Licker-in roller 23 utilizes the weave cotton cloth exit axis revolution of the counter steer of loom drive motors M.Like this, clamping rotor 44 is just to the direction revolution opposite with the arrow R of Fig. 1.Therefore, the wrong yarn Ym that is controlled by clamping rotor 44 and stationary clamping body 45 is just carried to the exit axis of weaving cotton cloth, and wrong yarn Ym frees under the clamping action of clamping rotor 44 and stationary clamping body 45.
Afterwards, make electromagnetic valve 18 demagnetizations, make defeated latitude stop the injection of nozzle 15 to stop.Then, make electromagnetic valve 16,17 excitations, defeated latitude is sprayed with pilot jet 13 with main burner 12 and defeated latitude.Follow-up weft yarn Ye, owing to still link to each other with wrong yarn Ym, so follow-up wrong yarn Ye accepts defeated latitude and reaches the jet action of defeated latitude with pilot jet 13 with main burner 12.Utilize this jet action, follow-up weft yarn Ye is drawn to defeated latitude direction, so wrong yarn Ym is peeled (tear) with main burner 12 sides from fell W1 by defeated latitude, is discharged and removes to defeated latitude end side successively.
In first embodiment of the Welf holder of loom of the present invention, can obtain following effect.
(1-1) when defeated latitude mistake takes place, be delivered to clamping rotor 44 as the inversion driving power of the press roller 24 of inversion driving device, make this clamping rotor 44 counter-rotatings.Therefore, the wrong yarn Ym that 45 of clamping rotor 44 and stationary clamping bodies are controlled is return direction and is carried to weaving cotton cloth, and like this, wrong yarn is freed under the effect of controlling of clamping rotor 44 and stationary clamping body 45.Utilization is controlled freeing of effect from this makes removing of wrong yarn Ym be treated as possibility.Therefore, constitute rotary driving force is passed the removing of wrong yarn from the latitude mistake to the Welf holder of clamping rotor 44 that can fail from press roller 24.
Be the translational speed of W of weaving cotton cloth (1-2) with the peripheral speed of the press roller 24 of the licker-in roller 23 association moving W input of will weaving cotton cloth.The peripheral speed of clamping rotor 44 will be harmonious with the translational speed of the W that weaves cotton cloth.But, as long as driving rotational body 36, driven revolving body 37, the diameter that drives Timing Belt wheel 40 and driven timing pulley 42 are suitably set, just no matter the peripheral speed of press roller 24 how to change the peripheral speed that can make clamping rotor 44 consistent with the peripheral speed of pressure yarn 24.Therefore, with the rotating press roller 24 of the peripheral speed identical with the translational speed of weaving cotton cloth as with so that clamping rotor 44 rotating positive rotary driving devices and inversion driving device are appropriate.
Taking off between licker-in roller 23 and press roller 24 when weaving cotton cloth W, be to reverse in the center by making press roller 24 with fulcrum 29 (1-3), press roller 24 leaves from licker-in roller 23.Even it is also constant to carry out the position of such operation fulcrum 29.Therefore, it is constant to be contained in the circumferential rotary track of the driving Timing Belt wheel 40 supported by fulcrum 29 and the Timing Belt 43 on the driven timing pulley 42.Its result acts on and this Timing Belt 43 is stretched or does not just exist from the phenomenon that belt pulley 40,42 comes off because of the too small Timing Belt 43 that makes of tension force that acts on the Timing Belt 43 because of crossing hightension.Embodiment 2:
