In preceding disclosed German patent application 199 51 410.3 early, do not advised that the length of cluster area should be made adjustable; In other words, the length of suction socket, the perhaps distance between the roll of drafting system exit pressure roller and the equipment upstream that the startup spinning is rotated in fibre structure.In this purpose is to produce to have the yarn of selectable yarn property in advance.In formerly not disclosed another piece German patent application 100 10 296.8, advise, be made at the lid of cluster area setting and can regulate it and transport the distance of element and/or can regulate its position in the fibre structure carriage direction.
Principle known (DE 199 31 253 A1) is further promptly settled a hollow profile element that links to each other with negative pressure source at the cluster area in drafting system downstream, and this cluster area is passed in a breathable conveyer belt operation.This hollow profile element is provided with a suction socket.Conveyer belt slides on the hollow profile element and is driven this sliding motion by a pressure roller, this pressure roller next the withdrawal roller of drafted device to driving.For this layout, its principle is considered to the boundling degree of fibre structure in the periodically-varied cluster area, its objective is to produce a kind of textured yarn.
The present invention is based on such problem, promptly further to increase the mode of the possibility that changes in textured yarn forms, further develops a kind of method and apparatus that relates to type in preorder.
The solution of this problem is that the boundling power that works at cluster area is changed according to predetermined pattern.
According to method provided by the invention, can specify described pattern by this way, promptly periodic variation boundling power perhaps changes boundling power in a kind of irregular mode, and is for example consistent with a kind of random process.The boundling power that acts in the boundling process that is applied to can be changed in this case, in individual other or every kind of intrinsic situation, therefore the pattern that difference is very big can be realized.
For addressing this problem, a kind of device is provided by this way, it is according to predefined mode operation, the boundling power that this pattern works at cluster area in order to temporary transient change.
More characteristics of the present invention and advantage from following to by deriving the explanation of the embodiment of accompanying drawing performance and the dependent claims.
Fig. 1 illustrate one have a drafting system and a ring spinning apparatus according to air-flow beaming device of the present invention.
Fig. 2 A is a vertical view of taking from the details of Fig. 1,
Fig. 3 A is a view of taking from the improvement details of Fig. 1,
Fig. 4 A is a view of taking from another improvement details of Fig. 1.
According to the embodiment among Fig. 1, rove 11 goes out from 10 drawing-offs of rove bobbin, and it enters drafting system 13 through a sley point or cord roller 12 transmission.In drafting system 13, rove 11 is stretched to required fineness of yarn.A spinning rotation is applied rove, and this rove is stretched to required fineness by ring spinning apparatus 14.
What be placed in cluster area between pressure roller 20 and the roll 24 is a cover plate 25, but its in-profile cooperates the profile of the cylinder 19 of air permeable, and is positioned in relatively the circumferential surface place near cylinder 19.By this cover plate 25; can obtain such state; promptly the cluster area of fibre structure between pressure roller 20 and roll 24 is protected on the one hand, and the air flow that is inhaled on the other hand is directed to and deflection by this way, i.e. its shunting passes across the circumferential surface of cylinder 19 as wide as possible.
Rise by means of several sections boundling power, and obtain certain boundling degree thus.At first, naturally, be the existence of suction airstream or do not exist or intensity separately.If suction airstream is discontinuous, so in fact can not get boundling.In order to obtain textured yarn, therefore suction airstream can be switched in the mode of rule or non-rule or cut off.In addition, resulting boundling degree depends on the position of described cover plate, and promptly the position that is placed with respect to the conveyer cover plate promptly more is close to pressure roller 20 or more is close to roll 24.In addition, the boundling effect also depends on the spacing between the periphery of cover plate 25 and cylinder 19.In order to change the boundling effect, provide such method according to a kind of regular or irregular mode, as among Fig. 1 with shown in the arrow 26 and 27 like that, change the position and/or the spacing of cover plate.
The boundling effect also depends on the length of cluster area, promptly depends on the spacing of pressure roller 20 and roll 24.In order to obtain the pattern in the yarn in this way, provide the method that changes roll location in regular or irregular mode along the direction of arrow 28.
If the clamping effect between roll 24 and the cylinder 19 is not enough to stop the spinning rotation that is activated to return and enters cluster area, the spinning rotation is returned and is entered into cluster area change boundling effect.In order to access a kind of textured yarn, thereby provide certain methods, by these methods, roll from cylinder 19 raise or at least load obtain discharging, according to a kind of regular or irregular mode, as shown in arrow 29.
As what be mentioned, the shape of the suction socket 23 of element 21 plays an important role in boundling.Preferably, as shown in Figure 2, use a suction socket 23 transverse to the carriage direction arrangement of fibre structure 11.If it has bigger width, can show a width of the fibre structure of multiple boundling, this suction socket 23 thereby also can carry out effective boundling.
If use the suction socket that extends straight along the carriage direction of fibre structure, it has played decisive role transverse to the width of carriage direction on the boundling effect.In this case, by the rule or change the suction socket width brokenly, can form a kind of textured yarn.This can accomplish by use-case device as shown in Figure 3.According to this embodiment, a pump unit 21 ' is provided, this element is provided with a long and wide especially suction socket 23 ', and this suction socket extends straight along the carriage direction of fibre structure.In this pump unit, laid element 30, can change the size of suction socket 23 ' by element 30 with a dividing plate mode.By the axial displacement along arrow 31 directions, the effective width of suction socket 23 can change between maximum and closed position, so thereby the boundling effect can change, and also can close fully.In order to obtain a kind of textured yarn, such mode is provided, can move forward and backward with a kind of rule or irregular pattern in the direction of arrow 31 by this mode element 30.In the embodiments of figure 3, further provide element 30, it can rotate at circumferencial direction with respect to suction element 21 in the direction of arrow 32.Determine the boundary line of both direction in order to the edge of this element of adjusting suction element 23 ' width by shoulder, so that by spinner member 30, the length of suction socket 23 ' also can be changed.In this case, the effective length of suction socket 23 ' can shorten on the one hand, at random reorientates in the direction of pressure roller 20 or to the direction of roll 24 on the other hand.In order to obtain a kind of textured yarn in this way, such mode is provided, can rotate with respect to suction element 21 with a kind of rule or irregular pattern with this mode element 30.
Fig. 4 has shown the further possibility that changes the boundling effect by the shape of suction socket and/or size.Be equipped with a super wide suction socket 23 " suction element 21 " in be provided with an element 33, this element 33 can rotate with respect to suction element by the direction of arrow 34 indications.Element 33 is provided with one or more suction socket 35,36,37, and they are by entering suction socket 23 along the rotation of the direction of arrow 34 " the zone as an effective suction socket.A straight suction socket 35 that extends along the fibre structure carriage direction can be provided in this case, or favour the suction socket 36,37 of the carriage direction of fibre structure.In the boundling process of fibre structure, the opposite direction of suction socket 36,37 tilts to have applied a S-rotation or Z-rotation.
In order to change boundling power, for element 33 provides such mode, even element 33 rotates in regular or irregular mode with device shown in Figure 4.In this case, rotation can so be carried out, and promptly two or three suction sockets 35,26,37 replace mutually, or this is at suction socket 23 " blind end and the suction socket 35,36 of one or more difformity and/or different size, change between 37.
Can obtain pattern very inequality by the present invention, depend on apply boundling power, according to every kind of mode or with another different combinations.Therefore can produce a kind of textured yarn, it not only partly is made up of boundling and non-boundling, and more can be by with programmable form boundling alternate with each other, and non-boundling forms with different cluster areas.
The present invention can certainly be applied to as in the disclosed beaming device of DE 199 31 253 A1.In this case, also can be provided with suitable adjusting device corresponding to the cover plate of cover plate 25, also be the same for the element of roll and hollow profile, can be changed with the position and/or the shape of the method suction socket.
