Definitions
- the invention relates to a method for operating a Weft distributing device of a row shed weaving machine with a feed nozzle and with an injector nozzle a weft against the direction of rotation Webrotors in a connecting channel between one Blow in the stationary ring part and a weaving rotor, whereby the weft from the connecting channel into one Gun tube is deflected and after its entry in Entry direction seen behind the shooting tube is clamped and cut to create a result to suck back the new weft thread tip and against the Direction of rotation of the weaving rotor in another shooting tube to blow.
- Such a device is in EP-A-0 433 216 described.
- This Task is accomplished in that way seen first one spatially at the shooting tube Cutting device and then one Clamping device is arranged and that temporally seen one before pinching the weft Retraction force is generated in the connecting channel, which Braking in the clamping device supports and during cutting between loops Shot tube and clamping device prevented.
- This procedure has the advantage that the weft is against Is braked and tensioned in the compartment at the end of the run-in and after its mechanical clamping in the Clamping device no longer to the clamping device runs after.
- the actual stop blow is through the Clamping device generated and intercepted during the Retraction force is so great that it runs after the low thread mass between the connecting channel and Clamping device prevents cutting the To allow weft in tensioned condition.
- the accuracy of the cropping also depends on the Repeat accuracy when driving the injector nozzles and any additional nozzles. It is therefore advantageous the air impulses through an open timing chain and Kinematic connection of the control valves with the To generate rotary motion of the weaving rotor. Because several Weft threads braked one after the other, under tension must be cut and redirected is a Rotary vane, which the air impulses one after the other assigns the relevant weft nozzles, a particularly inexpensive and accurate solution. Thereby, that an element with little scatter in its Opening and closing characteristics of all injector nozzles or all additional nozzles are controlled Repeat accuracy high. In addition, by adjusting on this one element, the impulse for everyone on it connected nozzles are changed.
- the invention is based on a Embodiment shown.
- Figures 1 to 4 each show schematically one developed cut across the parting plane between Weaving rotor and stationary ring part and each along the Connection channel for a weft thread, being schematic the process for reversing a weft is shown.
- Fig. 5 shows a kinematic via gears with a Webrotor connected rotary valve, the different Can feed injector nozzles in succession in one cycle.
- the figures are one Weft distributing device for one Row shed weaving machine, in which a weft thread in fed a connection channel via a feed nozzle and within the connection channel Gun tubes are distributed.
- a weft thread in fed a connection channel via a feed nozzle and within the connection channel Gun tubes are distributed.
- To be trouble-free Cutting the registered shot and reversing the Reaching a new weft tip is one Cutting device spatially between the shooting tube and Clamping device arranged so that before stopping the weft through the clamping device already a retraction force by means of the feed nozzle and injector nozzle and a loop under this retraction force be formed.
- While stopping in the Clamping device is the thread in the cutting device preloaded and can be cut easily.
- the Loop stretches and a new weft thread tip is entered in the next shot tube.
- a takeover ring 20 connected to the weaving rotor 8 turns in direction of rotation 7 and turns in with little play a parting plane 13 to a stationary ring part 11.
- the connecting channel arranged on a certain radius 3 is through a pocket 21 in the fixed ring part 11 and through a cut groove 14 in the take-over part 20 educated. Only in the area of scraper shoulders 10 the gutter 14 interrupted.
- a weft thread 9 is used constant speed via a feed nozzle 1 delivered and at an acute angle against the Direction of rotation 7 of the takeover ring 20 in the Blown in connection duct 3.
- an injector nozzle 2 coaxial with the Feed nozzle 1 is provided.
- a Additional nozzle 16 attached opposite to the direction of rotation can blow into the rotating channel 14 to the Transport of the weft thread during reversing support.
- each Scraper shoulders 10 the airflow and the weft 9 into the shooting tubes 4, of which the weft past a clamping device 6, 6 'into a row compartment the web rotor is transported.
- the groove 14 is excluded deeper and provided at their bottom with relief openings 18, to redirect airflow and weft into that Shooting tube 4 'to facilitate.
- the pull of the Additional nozzle 16 is only really effective when the deeper Part of the channel 14 in the area of the pocket 21 moved in and a continuously large cross section in the Connection channel 3 is formed (Fig. 3).
- the weft 9 runs freely from the Feed nozzle 1 against the direction of rotation 7 in the Connection channel 3 and further into the shooting tube 4 and a row compartment, not shown.
- the open one Clamping device 6 is shown as rotating, while the cutter is shown as stationary is.
- the deflection into the shot tube is along the stripping shoulder 10, which has an obtuse angle 12 (Fig. 3) to the parting plane 13 forms.
- the connection channel except for the little exempt Part of the channel 14 closed so that the Main air flow goes through the shooting tube 4.
- the weaving rotor 8 has the takeover ring 20 noticeably on the open cutting device 5 moved to.
- the additional nozzle 16 can be operated to to generate a negative pressure in the region of a slope 22, which supports the reversal when the larger one Cross section in the connecting channel 3 (Fig. 3). Feed nozzle 1 and injector nozzle 2, if the latter already is pressed, still blow against the slope of the blunt Angle 12 of the scraper shoulder.
- each injector nozzle 2 at a certain angle of rotation of the edge of the Scraper shoulders 10 a precisely defined air pulse receive.
- a rotary valve rotating in one direction 23, 30 pressure pulses in from a compressed air supply line Impulse lines 31 to the various injector nozzles conducts and simultaneously with the weaving rotor on which the Stripping shoulders 10 sit, kinematically e.g. about Gear wheels is coupled is shown in Figure 5.
- Of the Rotary valve 23 is with its housing base 24 on the Side wall 29 of a row shed weaving machine attached so that his drive gear 32 with a gear 33 of the Web rotor is engaged.
- the disc has an opening 41, the while rotating on a circle behind it individually arranged at regular intervals Recesses 43 in the middle part 25 sweep and each for the period of the breakthrough of breakthrough 41 and Recesses 43 generates an air pulse.
- the number of Recesses 43 corresponds to the number of injector nozzles 2 in stationary ring part 11 (Fig. 3).
- the air pulse is in the Middle part 25 via radial channels 44 to the respective Impulse lines continued, for which only those Connection bores 31 are shown. If the Impulse lines are also of the same length, then the air impulses come in the same way and with a high rate Precision at the scheduled time for the Injector nozzles 2 on. Through the direct drive via the Webrotor are the impulses even with speed changes and correctly synchronized when starting. In the further the simple mechanics are characterized by a high Operational reliability over long time intervals.
