Technical field
The present invention relates to the device for removing mixed weft from the projectile shuttle path of sheet woven fabric machine and use such device
The method removing mixed weft.
More particularly it relates to device as above, it during being inserted the loom stopping caused by mixed weft
Remove mixed weft outside race temporarily.
Background technology
In the routine operation of loom, it may occur however that the situation that weft yarn is only inserted partially into, this is because regular from knitting
The weft yarn that cloth machine side is inserted does not arrives its opposite side.This fault is likely due to the defect of weft yarn or due to the insertion phase
Between the excessive pressure that is applied on weft yarn, cause the weft yarn machinery broken end when being brought into race, or owing to weft yarn is from feeding
Yarn sheet shuttle or the early release of traction projectile shuttle, or again due to when traction projectile shuttle exchanges with yarn feeding projectile shuttle in the middle of the race,
Traction projectile shuttle fails to pick up weft yarn.In brief, above, three kinds of irregular weft yarns insertion information slips are shown as:
-staplings,
-lose latitude,
The exchange missed between-projectile shuttle,
Or, in general, it is expressed as " mixed weft ".
When occur these irregular weft yarns insert in a kind of time, be arranged in the reception of loom owing to not having weft yarn to pass
The specific sensor of side, loom central control unit is detected immediately upon it, and causes the guiding of loom to shut down.
But, the inertia of the parts that this shutdown is being moved due to loom, and depend on owing to mixed weft occurring
And the speed of machine does not highly generally terminate with it in same weft yarn mixed weft occur inserts circulation when causing shutting down, and
It is to terminate during ensuing circulation.Therefore, once it is determined that shut down, it is necessary to the circulation of reverse drive loom requirement
(usually one or two circulation), to bring it back into the same position that mixed weft inserts, manually or automatically to remove this
Weft yarn, then restarts loom.
The moment that loom is shut down is performed, it is possible to create shortcoming, this is because its front end of mixed weft is the most only above
The intermediate point arriving race is more or less lax, therefore forming part part coil outside race in race.
Although the lax weft yarn in race does not cause any inconvenience, because it is immediately by crossing and the beating of reed of warp thread
Catch, but weft yarn lax outside race contrary self along random paths arrangement；Therefore there is it and be carried out idle stop wink
Between yarn feeding projectile shuttle accidentally catch on and by the misplaced excessive risk in race of such projectile shuttle, textile defect may be caused.Thing
In reality, because display and weft yarn cutting apparatus synchronize shutdown with loom halt command, so mixed weft is not the most cut off,
Additionally, its weft yarn being still through catches.Therefore, according to the toughness of weft yarn, be fed the traction of yarn sheet shuttle mixed weft cutting or
When tearing a number of warp thread, such shortcoming may become notable, therefore adds the seriousness of shortcoming and extends dimension
Repair the time.
The problems referred to above are not the most solved satisfactorily by prior art, propose mechanical tong Weft handling device in prior art, for electricity
Dynamic or pneumatic weft yarn arresting hook form, it makes the loom structure that have accumulated in the region of a large amount of device complicated, and it is adjusted
Speed and the efficiency of joint are unsatisfactory.It is true that yarn feeding projectile shuttle enters continuously during loom stopping signal and loom are shut down
Enter the available time between race the shortest；Additionally, mixed weft is lax, hence in so that mechanical hook is not easy to catch it.
Summary of the invention
Therefore, it is an object of the invention to provide a kind of with conventional device compared with there is diverse concept and operation
Device, it can simply and efficiently solve disadvantages mentioned above, be reliably prevented mixed weft and cross yarn feeding sheet at loom stop moment
Location, shuttle ingress path ground.
This purpose is by having the pneumatic mixed weft removal device of the feature limited in appended claims 1 and 8 and being correlated with
Application process realize.Other preferred feature of such device and its related application method limits in the dependent claims.

Detailed description of the invention
Being clearly shown that as in Fig. 1, the structure according to the device for removing mixed weft of the present invention is extremely simple, including
The electronic valve 1 controlled by loom control unit, compressed air supply system 2 and the tubule 3 for air distribution exist respectively
Trip and downstream are connected to this electronic valve, and tubule 3 has a series of hole 4 on its side surface, serve as compressed air jet discharge
Nozzle.
Electronic valve 1 size is little and thickness is the least, is positioned at the sliding guidance of yarn feeding gripper band with therefore can be without problem
At the side of part G, as shown in Figure 2 so that tubule 3 will be arranged in weft yarn with same guiding piece G (Fig. 3) abreast and introduce machine
Weft yarn guides bar F to guide bar to select to be transferred on projectile shuttle path with the latitude being inserted in race by this weft yarn
In region between yarn and the edge of forming fabric, i.e. race entrance.It is apparent that electronic valve 1 can be by arbitrarily other type
Remotely operation valve substitute.
Tubule 3 is fixed along guiding piece G so that hole 4 be arranged in order to by compressed air jet vertically be channeled out feed
Yarn sheet shuttle guiding piece G, and preferably boot up.Described hole can be longitudinally-aligned along tubule 3, or can also laterally that
