Twisting spindle, especially for twisting textile threads

The present invention relates to an unwinding twisting spindle, in particular for twisting textile thread, which can be drawn off in an adjustable manner from a spool clamped on a sleeve The bushing remains relatively in the cows in the course of the twisting process and possibly with putty is provided for a loose rotation of the coil so that it is out of the range of action of the driver torque rotating G-liedes comes, on which the mentioned sleeve is arranged is and the one disc with a cage surrounding the coil and a means for moving the Emphasis of the dancing system carries.

solved, which means the division of a wire or two wires to the twisted material per revolution of the twisting spindle.

In Intereose the power increase of twisting spindles one is generally seeking to increase the speeds of the twisting spindles, resulting in all cases to a Yerklirzung inrer life which many of sometimes insufficient ochmierung in the Re &: befindlicher el in dusty environment of moving parts on through vibrations , which are caused by inaccuracies in the individual bearings, and finally by the demands made by the jigs, which are caused by extremely high speeds and the weight of the twisted material.

Another important component of the known twisting spindles is ilirein “ro-Jen G-erärm, which is partly for the reasons given and partly also by ventilation £ v. ^r irkun: which is caused by rapidly rotating parts of the twisting spindles.

The invention eliminates the cited clay gels and creates a highly productive twisting spindle with acceptable noise and service life, which meets the most demanding requirements with regard to the quality of twisted oil.

The main characteristic of the present invention is that

of the twisted material can be achieved, or how As explained further, it is possible to use this number of wires using different ratios Need to change.

The twisting spindle according to the invention consists of two Twisting systems together, with a twisting system being an independent contains stored work 10, in which a bobbin 101 with a winding dte to be twisted together Uateriales, for example cord, is located.

The material on a spool is made up of the cone a larger number of threads wound next to each other. The following description is for reasons for the sake of simplicity, however, only one thread a is mentioned.

The coil 101 is secured with the aid of securing means 102, 103 clamped on a rifle IO4, which in the course of of twisting remains relatively calm. The mentioned sleeve 104 is provided with a Lcneibe 105, which with a circular shape formed from several rods 106 Cage equipped with these rods 106 the coil IUl um.jeben ur.a eir.er.

Instead of some rods 106 or between them, there is a means 108 that shifts the center of gravity aee ranzen '.Verkes lü caused, this means 106 becomes with the help of an appropriately designed weight educated.

The support ring 107 is with an ireirse 109 for Provide thread a. This door brake is supported by a tiltable

Staff 110 carried. Those with a regulating member 111 equipped thread brake 109 is arranged centrally in its working position with respect to the work 10. Just like that like the sleeve 104, the thread brake 109 remains relatively at rest during the course of twisting.

The described work 10 is associated with a rotary distributor 1, which has at least one thread guide eye 2 is provided for thread a.

With this rotary distributor 1, the work 10 is assigned to a driver member 201 of a supporting structure 20, however with the difference that work 10 is on the affiliate link 201 is rotatably arranged by bearings 112 and 113, while the rotary distributor 1 is on the driver link 201 is stuck.

The described independent work 10 forms together with the Hotationsverteiler 1, as explained in more detail below, Means for forming a first and second wire of the thread a.

The member 201 of the structure 20 is through La ^ er 202, 203 on one in the opposite direction rotating main shaft 204 arranged rotatably, the hollow central part 205 on one side with a Yarn guide eye 206 and on the other hand with a guide pin 207 and a radial opening 208 for the exit of the thread a is provided. The main shaft

204 is rotatably arranged by bearings 209 and 210 in a stationary sleeve 211, which is closed with a Deekel 212, in the vicinity of which the end of the main shaft 204 with a Hiemensche: be 213 is provided.

The carrier link 201 provided with a radial opening 214 for the passage of the thread a is wider prepared for the placement of bearings 215 and 216 on which a stationary jacket 217 rests, which is similar like the independently stored work 10 with a means 216 is provided, which is a shift in the center of gravity of the stationary Lantels 217 caused. In the e.g.

means 21β formed by one gate is by two Bearing 219 and 22u a pin 221 with a Ke.jel gear 222 rotatably arranged, which between one of bevel gears 223, ^ 24 formed gear is used. The helical gear 223 forms one part of the clutch member 201, while the bevel gear 224 from the hollow central part 2U5 of the r main shaft 2Ü4 and from a zv / eiten Rotary distributor 3 is detected centrally, which has at least one thread guide eye 4 for the thread a.

The hollow central part 2 ^ 5 of the main shaft 204 creates attached to the i-main 204 together with the mentioned one Rotary distributor 3 means to form a third and fourth wire on the thread passing through a.

That is a shift in the center of gravity of the stationary edge 217 causing üdttel 218 is with a Pin 225 for receiving an arm 226 and two

superimposed support rings 227 and 226, which interconnected the from ot & ben 106 formed jväfig of the independently stored plant 10 surround"

It is possible to use the coil 101 of the movement 10 to be arranged in such a way that they result in simple accommodation The displayed la ^ er nods between coil 101

and sleeve 104 loosely rotates on the latter, which is the trigger of padding a from the side of the coil 101 is particularly advantageous is so that the coil 101 comes out of the »effective range of the driving torque of a rotating member, which in the case described would be the carrier song 201.

The twisting spindle works as follows:

The thread a slips when the spindle is active of the bobbin 101 to after braking in the yarn brake 109 around the support ring 107 through the yarn guide eye 2 of the rotating distributor 1, from where the thread a through the radial opening 214 of the driver member 201 penetrates into the hollow 2, vertical part 205 of the main shaft 204. From this the thread a relangs over the guide pin 207 passed through the further radial Opening 2Or aer the main shaft 204 in the thread guide eye 4 of the second rotary distributor 3 · From this one strikes.der Thread a around the two support straps 227, 22ö in the one above the thread brake 109 in the axis Thread is good 5, aas which he ir. Direction to further deduction or winding means, not shown got.

The individual wires of the thread a become as follows achieved: by the fact that the thread a slips off or off the side of the bobbin lül; espult in the thread brake 109 is introduced, forms in this section the first wire of thread a, which is approximately in the section from the thread brake 10 $ to the thread guide eye 206 in the hollow central part 2O5 of the main shaft 204 is doubled by the rotary distributor 1. In the subsequent sections, as far as the direction of rotation If the twisting system should not change, it would lead to a renewed untwisting of the double wire already achieved earlier come, v / it is necessary that the following Twisting system has an opposite direction of rotation.

Then α em a thread having a double wire becomes approximately in uei.-Jer.ii ■>. ι. Section which is delimited by the thread guide run 06 of the right central part 2ü5 of the main shaft 204 and by the thread guide 4 of the second rotary distributor I is given a third wire.

After the twisting spindle contains means, which a shift of the center of gravity bowohl of the sleeve 104 as cause of the fixed üiantel 217, the The twisting spindle only works in a horizontal position or in a position that is approaching it, otherwise these means would have to be carried out by others Organs such as magnetic elements and the like can be replaced.

In the cited embodiment of the twisting spindle according to the invention, this is between the individual systems The gear ratio 1: 1 is selected, but this is achieved by selecting the bevel gears 222,223,224 or Use of another type of transmission gear, e.g. differential planetary gear, variator, if necessary Use of an independent drive for each system is so variable that the number of revolutions a twisting system can be changed as required.
