In the embodiment shown in Figure 2, the suction nozzle 12 of winding position 2 and yarn-clipping tube 25 are seated in its so-called yarn respectively Merging state.

That is, suction nozzle 12 fetched from cross winding bobbin 15 the loose thread of upper yarn 31 and via yarn merging seam 20 by its It is sent into and connects the connecing in yarn channel 19 of yarn prism 23, and be generally secured in yarn tensioner after the cutting of controllable clearing , the loose thread of lower yarn 32 being connected with spinning bobbin 9 is obtained by yarn-clipping tube 25 and stitches 20 via yarn merging and be also threaded Enter to connect connecing in yarn channel 19 for yarn prism 23.

The yarn prism 23 that connects also being open upwards during connecing yarn is for example threaded 27 at this time and is connected to master Furthermore the holding shredding tubule 18 of acceptable air-flow is added in body 22 in main body.

Also as shown, the loose thread of upper yarn 31 is also threaded the gripper member 11 ' of yarn clipping cutting mechanism 11 and is set to down Side yarn clipping cutting mechanism 17 yarn blank 17 " in, the loose thread of lower yarn 32 is accordingly connected into lower yarn clipping cutting mechanism 17 Gripper member 17 ' and upper yarn clipping cutting mechanism 11 yarn blank 11 " in.

It is being constituted according to the present invention, can by pivot center 40 move pivotally bearing and can pass through it is (unshowned) drive The yarn feeding device 30 that dynamic device is controlled by regulation has two guide legs 35 and the so-called yarn being made of two arms is drawn Auxiliary body 13.

At this point, the arm 36 that yarn draws auxiliary body 13 is so placed on yarn feeding device 30, that is, the arm is in such as Fig. 2 Shown in yarn feeding device 30 connect the connecing in yarn channel 19 of yarn prism 23 positioned at being set to for upper yarn and lower yarn 31,32 when inwardly pivoting Loose thread lower section.That is, the yarn extraction being seated in below the loose thread of upper yarn and lower yarn 31,32 during connecing yarn is auxiliary The arm 36 of mechanism 13 is helped to catch yarn of the engagement yarn simultaneously while for that will repair in lower section when yarn feeding device 30 is pivoted out What line passed through that 20 ground of yarn merging seam send out that this connects yarn prism connects yarn channel 19.It, can be smooth using the yarn therefore exposed Ground starts to carry out conventional winding process, i.e., starts winding position 2 again according to the rules.

Fig. 3 shows yarn splicing device according to prior art to overlook, here, for better very clear consideration, Yarn splicing device 10 connect yarn prism 23 and affiliated yarn feeding device 30 is slightly shown spaced reciprocally.

In an illustrated embodiment, yarn splicing device 10 have including be subjected to air-flow connect yarn channel 19 connect yarn prism 23, connecing yarn channel can be placed in by yarn that is relatively wide, being preferably disposed in 41 region of central longitudinal axis for connecing yarn channel 19 Seam 20 is close.

Multiple compressed airs are blown into hole 42 and are passed through that cross section is preferably rounded to connect yarn channel 19.

In addition, the yarn channel 19 that connects for connecing yarn prism 23 is closed during connecing yarn by cover piece 43.

In the yarn splicing device 10 constituted in this way, engagement yarn can after connecing yarn process, i.e. winding process again Pass through 20 sliding of yarn merging seam relatively wide, being arranged in 41 region of central longitudinal axis for connecing yarn channel 19 when starting at once Connect yarn prism 23 out connects yarn channel 19.

That is because yarn splicing device 10 slightly bounces back arrangement about normal yarn movement path as known, Once therefore cover piece 43 is taken off, then engages yarn and got rid of automatically to conventional yarn movement path.

However, it is known that yarn splicing device 10 exactly manufactured because of its cover piece 43 complicated and correspondingly cost compares Intensively.

Fig. 4 shows the embodiment of the yarn splicing device 10 constituted according to the present invention to overlook.

Yarn splicing device 10, which has, connects yarn prism 23, and connecing yarn channel 19 is spacious logical during connecing yarn.In addition, connecing yarn Device 10 draws auxiliary body 13 equipped with yarn feeding device 30, equipped with yarn according to the present invention,

Herein, also for preferably it is very clear for the sake of and show connecing for yarn splicing device 10 with being slightly spaced from each other Yarn prism 23 and the affiliated yarn feeding device 30 constituted according to the present invention.

As shown, yarn splicing device 10 have include acceptable air-flow connect yarn channel 19 connect yarn prism 23, this connects Yarn channel can be by approaching about 41 side of central longitudinal axis for connecing yarn channel 19 to the yarn merging seam 20 being staggeredly arranged.

Multiple compressed airs so arranged, which are blown into hole 42 and are passed through, connects yarn channel 19, i.e., avoids blow flow from directly blowing as far as possible To yarn merging seam 20.

Because yarn splicing device 10 in installment state is slightly returned as common about normal yarn movement path Contracting arrangement, therefore yarn also leaves towards conventional yarns motion path at once after yarn feeding device 30 lifts connect yarn channel herein 19。

But as in the previous embodiment be not necessarily to cover piece with regard to it is workable and thus with arranged off-centre yarn Always have following danger in the yarn splicing device 10 of merging seam 20, engagement yarn keep being hooked on connect yarn prism 23 connect yarn channel 19 Protrusion component on, be as a result exactly, yarn can not leave connect yarn channel 19 and be then rolled up process starting when again fracture or It is impaired.

In order to avoid this point, there is yarn feeding device 30 yarn according to the present invention to draw auxiliary body 13, by two Arm 36 forms, which is seated in being located at during connecing yarn for upper yarn and lower yarn 31,32 when yarn feeding device inwardly pivots Connect the lower section for connecing the loose thread in yarn channel 19 of yarn prism 23.

That is yarn is drawn auxiliary when being pivoted back into its initial position after yarn feeding device 30 is connecing yarn process and terminates It helps the arm 36 of mechanism 13 to obtain engagement yarn in lower section and be passed through 20 ground of yarn merging seam reliably to send out and connect yarn prism 23 Connect yarn channel 19.

Then, winding process can successfully be restarted.

Equipped with the function of the yarn splicing device of the yarn feeding device constituted according to the present invention

During normally winding operation, the yarn feeding device 30 of yarn splicing device 10 is always parked on initial position, first at this On beginning position, the movement of yarn and loose thread is connected connects yarn prism 23 all not by the structure of yarn feeding device 10 into yarn splicing device 10 Part hinders.

That is the guide leg 35 of yarn feeding device 30 is located at by yarn movement path, and yarn draws auxiliary body 13 Arm 36 is located at below yarn movement path.

When winding occur and interrupting, because such as yarn clearer finds intolerable yarn flaws and has been turned on clearing to cut It is disconnected, therefore upper yarn 31 is fallen on first on cross winding bobbin 15, and lower yarn 32 is usually trapped within the yarn tensioner of winding position 2 In.

Then, it has recorded or has started the station computer 29 that winding interrupts and be used to pass through suction nozzle 12 and catch yarn 31 Loose thread is simultaneously transferred to 10 region of yarn splicing device by the suction nozzle 12 that pivots downwards.That is, suction nozzle 12 will be guided through thread board The loose thread 31 of upper yarn 31 connected via yarn merging seam 20 and connect yarn channel 19 into connect yarn prism 23.

Subsequently or simultaneously, yarn-clipping tube 25 from yarn tensioner take lower yarn 32 loose thread and by its via yarn merging seam 20 Also it connects and connects yarn channel 19 into connect yarn prism 23.

Then, the loose thread of the loose thread of upper yarn 31 and lower yarn 32 is ready for connecing yarn process.That is loose thread 31,32 It is inhaled into as common and keeps in shredding tubule 18 and at least partly get rid of its yarn twist there.Ready loose thread Then it is positioned in as needed by yarn feeding device 30 and connects the connecing in yarn channel 19 of yarn prism 23.

That is the drive that the station computer 29 of related winding position 2 can be controlled by control line start by regulation Dynamic device, preferably stepper motor, pivot yarn feeding device 30 inwardly, thus the not only guide leg 35 of yarn feeding device 30 The loose thread of upper yarn and lower yarn 31,32 is connect into the connecing in yarn channel 19 of yarn prism 23 by being located in, and yarn draw it is auxiliary The arm 36 of mechanism 13 is helped to be placed in below the loose thread of yarn and lower yarn 31,32.

The guide leg 35 that loose thread to be joined passes through yarn feeding device 30 at this time is reliably fixed and connects yarn mistake in subsequent It is maintained in journey on its predetermined position.

Because the yarn channel 19 that connects for connecing yarn prism 23 keeps spacious logical during connecing yarn, therefore the extra yarn air that connects can also be suitable It escapes up sharply and connects yarn channel 19, to the almost Yarn connecting as yarn occur.

Then, station computer 29 is pivoted back into yarn feeding device 30 by accordingly controlling the driving device to look after Its initial position.

It is this back pivot when, yarn draw the arm 36 of auxiliary body 13 lower section catch engagement yarn and by it is light It is pushed through 20 ground of yarn merging seam and pushes conventional yarn movement path to from the yarn channel 19 that connects for connecing yarn prism 23.

That is, the yarn engaged according to the rules then slides back to it normally from the yarn channel 19 that connects for connecing yarn prism 23 Yarn movement path, so as to successfully start to be wound process again.
