Pitch winch spool handset station relatively it is known for a long time, Yarn twisting device has had in numerous patents to be retouched in detail
State.
By this Yarn twisting device, two formed for example, by yarn interruption means or controllable cleaning yarn knife
The end of a thread is pneumatically linked together, so as to form the joint actually as whole piece yarn.
For example after disconnecting, the so-called upper yarn run on the surface of cross wound bobbin cheese is drawn simultaneously by suction nozzle with battery unit
In the passage of splicing for being placed on the prism of splicing of Yarn twisting device.
Substantially while so-called yarn under working is crawled pipe is crawled from the unwinding cheese on debatching position, and
And be also disposed in passage of splicing, in yarn path on yarn and yarn under working and then be pneumatically splicing together.
However, it is necessary to meet these requirements so that such Yarn connecting is in appearance one actually with yarn
Cause, it may have almost identical yarn strength.
Both threads head is joined together needs and yarn for example is switched into accurate length first and carefully prepares to twist with the fingers
Termination process, is then accurately placed in the passage of splicing for prism of splicing.
Known Yarn twisting device includes a variety of devices to reach this purpose, such as thread grip and shearing
Device, holding and shredding pipe and fournisseur.
As described above, both threads head is transported to the area of Yarn twisting device by suction nozzle with battery unit and/or crawl pipe in practice
It is introduced in domain and by yarn guiding disk guiding in passage of splicing, yarn guiding disk is respectively placed in the end of the passage of splicing for prism of splicing
Portion.
During yarn advances to passage of splicing, the end of a thread is also positioned on yarn holding device and the yarn shearing of association
In device.
The line that accurate length is clipped to by yarn shear and is fixed by yarn holding device
And then head is sucked up in holding and shredding pipe, is pneumatically prepared there.This means that the end of a thread is significantly moved back first
Twist with the fingers and chopped fiber is also removed.
And then ready the end of a thread is led splicing in passage to prism of splicing by fournisseur, and two such the end of a thread is being spliced
It is abreast adjacent to each other almost in same level in passage, but arrange in a reverse direction.The length of free the end of a thread by
The material of yarn and/or the diameter of yarn are determined, are preferably highlighted in both sides from the passage of splicing for prism of splicing.
One or more pulse of compressed air in the access aperture of secant-shaped opening enter rib of splicing by corresponding, main
Post is spliced in passage, to ensure the rotation for being initially positioned at be substantially parallel to one another two the end of a thread spliced in passage, so that shape

According to the function of the Yarn twisting device of the present invention
It is well known that in intersected coiled bobbin handset, the two types that winder is interrupted are distinguishing.
First type, including the idle running of such as spool 9 to need execution is so-called to change pipe, that is to say, that positioned at winder
Position AS spool 9 or corresponding blank pipe must be replaced by new spool 9.
This order for changing pipe is known, and is had in detail on so-called circular bobbin magazine machine in such as DE19510171A1
Carefully describe.
Perform change pipe operation after, the new spool 9 with new yarn under working 32 is already prepared to, and new yarn under working
32, which can be crawled pipe 25, is placed into the passage 20 of splicing of pneumatic thread device of splicer 10.
Conventional yarn clearer cut-out or broken string above second of type that winder is interrupted, such as yarn tensioner, under
Yarn 32 is still remained in yarn tensioner, and due to lacking dynamic yarn signal, yarn clearer triggers the yarn of yarn tensioner
Line holding function.
The yarn under working 32 kept by yarn tensioner is crawled pipe 25 and collected, and the crawl pipe 25 is pivoted into yarn first for this
In the region of line tension device and aspirate the yarn under working 32 discharged by yarn tensioner of there.
When for example by be arranged on crawl pipe 25 in sensor (not shown) recorded successfully get yarn under working 32 when, grab
Pipe 25 is taken to be switched to operating position thereon as shown in Figure 2.Therefore yarn under working 32 is placed to the passage of splicing for prism 19 of splicing
In 20, and enter to yarn under working shearing and the yarn under working clamping device 17 of clamping device 17 and the shearing of upper yarn and clamping device
In 17 and/or 11 yarn cutting member 11 ".
At the same time, the upper yarn 31 run on cross winding bobbin 15 is drawn by suction nozzle with battery unit 12, is also placed
To splicing in passage 20 for device of splicer 10.As shown in Fig. 2 therefore suction nozzle with battery unit 12, which aspirates yarn 31, enters prism of splicing
19 splice in passage 20, and enter thread grip part 11 ', the lower yarn of supreme thread grip and shear 11 and/or 17
Wire clamp holds the yarn cutting member 17 " with shear 11 and/or 17.
Afterwards, passage 20 of splicing is closed, that is to say, that cover element 23 is moved to joint location by pivot drive 43.When
Closing is spliced after passage 20, and yarn shearing and clamping device 11 and 17 are activated, and yarn under working and upper yarn 31 and/or 32 are sheared
To predetermined length, the end of a thread cut of upper yarn 31 and yarn under working 32 is removed by crawl pipe 25 and/or suction nozzle with battery unit 12.
Afterwards, the end of a thread of the upper yarn 31 and yarn under working 32 that stretch out in passage 20 of splicing preferably pneumatically is pumped to energy respectively
Apply holding and the shredding pipe 34 of negative pressure and release negative pressure, yarn rotation and chopped fiber are sucked at least in part.
After this, therefore the end of a thread of ready upper yarn 31 and yarn under working 32 is then act through so-called fournisseur and (do not had
Show) return in passage 20 of splicing, therefore the end of a thread 31,32 splice in passage 20 with it is predetermined it is overlapping be positioned adjacent to, i.e.,
The end of a thread of upper yarn and yarn under working 31,32 is arranged to their phase mutual energy and slightly stretches out in passage 20 of splicing.
For example, by the suitable control of magnetic valve, joint air is entered by inlet 22 in passage 20 of splicing afterwards,
And the fiber of the end of a thread in passage 20 of splicing of upper yarn 31 and yarn under working 32 is spun on together, so as to form actually
Durable wire terminal as yarn.
During described splice, joint air in a spiral manner via passage 20 of splicing exit opening 27 and/or
36 flow out from passage 20 of splicing, and such result is exactly, respectively in yarn guiding disk 41,42 and the exit opening 27,36 for passage of splicing
Between free space in, the ballooning of yarn for extending to adjacent yarn guiding disk is formed by air of splicing, the ballooning of yarn was being spliced
In journey the end of a thread of passage of splicing is stretched out in as other Yarn twisting and stably on the end of a thread.
It means that by the construction of the prism 20 of splicing according to the present invention, yarn guiding disk 41 and/or 42 and exit opening
27th, 36 set at interval, with cover element 23 and during splicing, the formation of the air ring is joined together for this, even for
