View middle bobbin spindle 2.1 at Fig. 1 and Fig. 2 is in wrapping range, and Spulspindelspulspindel 2.2 is in exchange area.The exchange of a spindle shown in Fig. 3, thus Spulspindelspulspindel 2.1 leads in exchange area, and Spulspindelspulspindel 2.2 leads in wrapping range.

In wrapping range, reciprocating apparatus 4 co-operatings that the hold-down roller 5 and that Spulspindelspulspindel 2.1 or 2.2 and is provided with above spindle bearing 3 is provided with above that.Reciprocating apparatus 4 has a reciprocal unit at each winding point, can guide a yarn respectively back and forth by them in a reciprocating travel.Hold-down roller 5 preferably can be rotated to support on the not shown fork and is fixed in the winding process of each yarn on the circumference of yarn tube to be formed.Hold-down roller 5 extends along the total length of Spulspindelspulspindel 2.1 or 2.2 basically for this reason.

Above reciprocating apparatus 4, each winding point is provided with a front yarn guider 17, and they constitute the introducing device (Einlauf) of each yarn 6 to each winding point of wire coiling machine.

In wire coiling machine shown in Figure 1, fixing four bobbins 7 altogether on Spulspindelspulspindel 2.1, thus incite somebody to action four one threads, 6 parallel each yarn tube that are wound into abreast altogether.In this embodiment of wire coiling machine, the number of winding point is exemplary.Basically on a Spulspindelspulspindel, can fix 8,10 or 12 or also more bobbin, so that with the reel for yarn coiled yarn tube of similar number.The 26S Proteasome Structure and Function of shown embodiment is irrelevant with the number of winding point.

Guiding yarn beam during spindle exchange when beginning the dividing sinker first of each yarn in process and during the course, one auxiliary device 8 is set, and it not only has when being used for first dividing sinker and guides the guide piece of each yarn but also have the guide piece that is used for guiding each yarn when a spindle exchanges.Auxiliary device 8 is made of a guiding clamp bar 9 for this reason, and it is arranged essentially parallel to Spulspindelspulspindel 2.1 and extends.Guiding clamp bar 9 also at one end is connected in support 11 along the total length extension of Spulspindelspulspindel 2.1 basically.Support 11 constitute can swing and be fixed in the frame 1 via oscillating axle 13.Be support 11 configurations one oscillatory gearing mechanism 12, thereby support 11 can guide guiding clamp bar 9 to a plurality of operating positions back and forth from a dead position.

On the guiding clamp bar 9 that is parallel to Spulspindelspulspindel 2.1 extensions, a plurality of thread-carriers 10 are set movably, so that between a plurality of positions, guide each thread-carrier back and forth along the longitudinal direction of guiding clamp bar 9.On guiding clamp bar 9, the number of thread-carrier 10 is entirely identical to the number of winding point in wire coiling machine, thereby is thread-carrier 10 of each winding point configuration.Here can motor-driven, electronic or pneumatically guide and be connected each thread-carrier 10.

For when process begins with a yarn beam dividing sinker in wire coiling machine that comprises threads, at first by an aspirator 14 guiding yarn beam.Aspirator 14 is preferably constituted a suction rifle and guide by an operating personal.For this reason for example by a preposition spinning apparatus by the aspirator 14 sucking-off yarn beam and the container that doffs that leads.For with in yarn insertion process device or the wire coiling machine, by operating personal hand guided aspirator 14.So at first each yarn 6 is inserted in each front yarn guider 17.But realize the form of implementation of the insertion of each yarn basically also known automaticly.

In order to further specify dividing sinker process first, referring now to Fig. 1 and Fig. 2 .1.As finding out,, guiding clamp bar 9 is directed to a side from a side in the dead position on spindle bearing 3 next doors is close to the top operating position of hold-down roller above spindle bearing 3 and Spulspindelspulspindel 2.1 in order to prepare dividing sinker process first by Fig. 2 .1.For this reason via oscillatory gearing mechanism 12 and oscillating axle 13 deflection supports 11, thereby will lead clamp bar 9 guiding top operating positions, it is called collection location here.

As special as seen from Figure 1, import to a collection location on the free end of guiding clamp bar 9 with being fixed on each thread-carrier 10 on the guiding clamp bar 9 movably.Each thread-carrier 10 is close to and is positioned at collection location side by side, thereby can insert each yarn 6 by operating personal with simple mode and method by the guiding of aspirator 14.After each yarn 6 inserts each thread-carrier 10, with it from its collection location dividing sinker position of leading.Dividing sinker shown in broken lines position among Fig. 1.In the dividing sinker position of each thread-carrier 10, each yarn 6 is assigned to each winding point.This moment, each thread-carrier 10 directly was a bobbin of fixing on the circumference of Spulspindelspulspindel 2.1 7 configurations.

In the extension that continues, the clamp bar 9 that will lead imports to a bottom operating position by support 11 from collection location.Fig. 2 .2 can illustrate such situation, and the clamp bar 9 that promptly leads is fixed on a bottom operating position, and it is defined as the dividing sinker position here.Start simultaneously one above reciprocating apparatus 4, be provided with draw yarn bar 18, make it avoid each yarn 6 having a down dip in reciprocating apparatus 4.Under the situation shown in Fig. 2 .2, each yarn 6 enters catching in the yarn opening 16 of each bobbin 7 on the circumference of Spulspindelspulspindel 2.1 respectively via the thread-carrier 10 of each location.For dividing sinker and the seizure of each yarn 6 on each bobbin 7, be rotated in a clockwise direction the spindle bearing 3 that comprises Spulspindelspulspindel 2.1, thereby guide the coiling of each yarn 6 on each bobbin 7.This moment, the hand of rotation by each bobbin 7 that Spulspindelspulspindel 2.1 drives was that direction is identical with the yarn service direction.This situation meets a synchronous principle.Each yarn 6 is caught and is cut off by the yarn opening 16 of catching of each bobbin 7.For cut off yarn 6 preferred on each thread-carrier 10 in conjunction with an independent cutter sweep.

Begin winding process later on catching and cut off each yarn.The guiding clamp bar 9 that will comprise each thread-carrier 10 is led and is got back to the dead position of side on spindle bearing 3 next doors.This situation is shown among Fig. 2 .3.Draw yarn bar 18 from service the producing of yarn simultaneously, thereby each yarn 6 has a down dip in reciprocating apparatus 4.Can begin the coiling of each yarn 6 now to the yarn tube.

In the extension of process, for the continuous coiling of each yarn is directed to an exchange area from wrapping range with spindle 2.1 or 2.2 when the final diameter of the yarn tube that reaches a coiled.This situation shown in Fig. 3 will comprise that wherein the Spulspindelspulspindel 2.1 of each yarn tube of finishing coiling imports in the exchange area, thereby the Spulspindelspulspindel 2.2 that comprises each empty bobbin 7 enters wrapping range.For the yarn of each yarn tube 15 on each the empty bobbin 7 on the circumference of Spulspindelspulspindel 2.2 that can implement from the Spulspindelspulspindel 2.1 of complete coiled passes on, guiding clamp bar 9 is imported to another operating position between two Spulspindelspulspindels 2.1 and 2.2 by starting from dead position of oscillatory gearing mechanism 12.This operating position is called catches the yarn position.Catch the yarn position along the guiding clamp bar 9 a sliding edge guide each yarn 6.Each thread-carrier 10 at guiding clamp bar 9 upper supports is in its dividing sinker position under this situation.Therefore by drawing the startup of yarn bar 18, it takes each yarn 6 out of from reciprocating apparatus 4, and every one thread 6 is positioned on the guiding clamp bar 9 by each thread-carrier 10.Can begin of dividing sinker and the seizure of each yarn 6 now at each bobbin 7 of Spulspindelspulspindel 2.2.After catching and cut off each yarn 6 now, guiding clamp bar 9 is rotated back into the dead position of side on spindle bearing 3 next doors from catching the yarn position.Make the yarn bar 18 that draws above reciprocating apparatus 14 break away from the yarn operation simultaneously, thereby each yarn 6 have a down dip respectively in each reciprocal unit of reciprocating apparatus 4.Implemented the spindle exchange and each yarn has been wound into each new yarn tube on Spulspindelspulspindel 2.2.In later time, replace each quota yarn tube fixing on Spulspindelspulspindel 2.1 with each new bobbin.

Should mention clearly in this respect, the operating position that constitutes in the embodiment by Fig. 1 and 2 of guiding clamp bar 9 is exemplary.For example might make that to be called the bottom operating position of dividing sinker position when dividing sinker first be identical with the yarn position of catching when a spindle exchanges.But it is possible also still having other additional midway location, and they can occupy guiding and the location that is used for each yarn by the guiding clamp bar.In this respect importantly, not only each yarn can be implemented by guiding clamp bar 9 together to the radial runout of the direction of Spulspindelspulspindel but also to the skew of the direction of Spulspindelspulspindel.

For with each on guiding clamp bar 9 movably thread-carrier 10 be positioned between a collection location and the dividing sinker position embodiment of a possible mobile drive deivce shown in Fig. 4.Be this birds-eye view that guiding clamp bar 9 is shown among Fig. 4, its at both ends is bearing on the oscillating axle 13 swingably by each support 11.One hauling rope 19 is set on support 11, it is guided between the two positions back and forth via a straight line actuating device 20.Fixing one on hauling rope 19 is the thread-carrier 10.1 of the end configuration of guiding clamp bar.Therefore can between a dividing sinker position and a collection location, guide thread-carrier 10.1 back and forth.

Be connected with 10.4 by a connecting device 21 and remaining thread-carrier 10.2,10.3 via the thread-carrier 10.1 of hauling rope guiding.As connecting device 21 band is set here, it is fixed on the end of guiding clamp bar 9, and has the length of a definite corresponding dividing sinker position, locatees thread-carrier 10.1,10.2,10.4 there.Can gather a collection location on the right-hand member of guide clamp bar 9 by will lead whole thread-carrier 10.1-10.4 on the clamp bar 9 of the manipulation of hauling rope like this.By restarting of hauling rope,, realize the location of thread-carrier 10.1 to 10.4 over there in corresponding dividing sinker position so that the left end of thread-carrier 10.1 to guiding clamp bar 9 moved.Thereby realize each yarn selecting on each winding point in wire coiling machine.
