Abstract
The invention relates to a preparation method of core-spun yarn (8), which is characterized in that: the core yarn (6) is lead to a plurality of fibre slivers (1) before the fibre slivers (1) are merged because of rotation; the preparation method specifies that: before the core yarn (6) is merged with the fibre slivers (1), the core yarn is inspected, in particular the fractures of the corn yarn are monitored.
Description
Technical field
The present invention relates to make the method and the device thereof of composite yarn, particularly used the cladded yarn preparation method and the device of heart yarn broken end monitoring device.
Background technology
Known method is made composite yarn and is: during merging in the fiber skein drawing-off and by rotation, heart yearn be inserted in the fiber skein and covered fiber around its rotation, cause heart yearn no longer visible as much as possible.Use this method, for example process elastomeric yarn.The intensity and the elongation of the composite yarn that heart yearn has determined to be generated basically, and covering yarn has determined the grasping force and the outward appearance of yarn especially.Therefore, composite yarn is used as heart yearn usually, and staple fibre is most as holding line, and staple fibre is such as being cotton and/or wool.
For example being produced on DE 195 01 163 C1 or also having among DE 198 15 054C1 of composite yarn is described.
Summary of the invention
The present invention is based upon and improves and quicken on the problem of production of composite yarn.
Once advised monitoring the fracture of heart yearn for solving said problem, the fracture before particularly merging with fiber skein.
Whether utilize this monitoring, will discern heart yearn very fast and rupture, therefore can implement the intervention to spinning process very fast, this intervention, and cause as soon as possible composite yarn is carried out further suitable processing if will reduce the fracture of fiber.
Said monitoring can realize in any desired way.Be designed with: machinery monitoring system or Optical devices or also have the monitoring device of capacitive or inductance type, the existence of mechanical system monitoring thread reserve, Optical devices monitoring heart yearn.Yet other possibility also should be contained in the present invention.Crucial unique factor is that yarn breakage should be identified as soon as possible.
Yet,, can also confirm whether heart yearn meets predetermined specification except yarn breakage.These specifications for example can relate to its shape or form.For example, if the diameter of heart yearn less than desired boundary value, equally also can be discerned by monitoring device.For example,, also can use this monitoring device if heart yearn has special cover layer, this cover layer can by with color and be identified.Present invention includes the possibility that is used to monitor that all can be expected.
Specifically, the present invention proposes the method for making composite yarn, thus before fiber skein is merged through rotation; Heart yearn is directed to the fiber skein place, before heart yearn is incorporated into fiber skein, monitors the crack conditions of heart yearn, for heart yearn is provided with roller; Said roller rotates with heart yearn; Implement to monitor the rotation of said roller through Optical devices, it is characterized in that:, be provided with the catoptrical transmitter of the rotatable parts of the said wheel of emission for optical pickocff as the optical pickocff identification of recipient reverberation from the rotatable parts of wheel; Reach optical pickocff with making said reverberation pulsation, this means that roller is rotating.
In a preferred embodiment, for heart yearn is provided with roller, it rotates with heart yearn.The rotation meeting of this roller is observed.In a simple embodiment, this can be accomplished by Optical devices, because for example, as the respective optical sensor identification of the recipient reverberation from the wheel each several part, for example from the reverberation of spoke, disc or wheel hub.In the case, for optical pickocff is provided with transmitter, the light of its emission is reflected.Reach recipient to this light pulsation, this means that roller rotating, does not promptly have yarn breakage.Yet, be static and heart yearn has ruptured if the constant signal of recipient emission, this means roller to monitoring device.
Even for discern be very easy to motion roller still rotating the yarn breakage that has just taken place, can therefore,, also will send alarm signal in the limiting value input control device even specific pulse cycle is weakened.
Preferably be provided with roller, wherein contain a whole set of checkout gear that is useful on the rotation that detects roller at the pivotal arm place.This is applied to above-mentioned light source and recipient especially, thereby, like the similar ground of pointing out, front, also can use other checkout gear.
Preferably with switch arrangement in the pivotal arm place, if when the special moment no longer needs checkout gear, available this switch cuts out said checkout gear.
Description of drawings
Other advantage of the present invention, characteristics can and learn that based on each accompanying drawing each accompanying drawing is depicted as from preferred embodiment:
Fig. 1 has heart yearn, transport, reaches the schematic side view according to the drafting system zone of its monitoring device of the present invention and spindle row; With
Fig. 2 is according to the amplification exploded view of the heart yearn monitoring device of Fig. 1.
The specific embodiment
In Fig. 1, fiber skein 1 is conducted through drafting system 2 and drafted in known manner or refining at this place.Drafting system 2 mainly contains known top roller 3.1-3.3 and bottom roll 4.1-4.3, thereby top roller 3.2 and bottom roll 4.2 interact with same known apron 5.1 and 5.2.
Before top roller 3.3 and bottom roll 4.3, fiber skein 1 is directed to the receptacle 7 of this heart yearn of heart yearn place from heart yearn 6.
For example, as described in DE 198 15 054 C1, heart yearn combines with fiber skein 1.Both become composite yarn and leave drafting system 2 to the direction of yarn socket 9.Before operation on the socket 9, composite yarn 8 passes another cable guiding device (pigtail shape twizzle) 10 and steel traveler 11.
Between drafting system 2 and heart yearn receptacle 7, arranged monitoring device 12 for heart yearn 6.Monitoring device 12 has the bracket arm 13 that joins on the outer cover, and bracket arm 13 is connected in pivotal arm 15 through connector 14.Roller 16 is positioned at the free end of pivotal arm 15, and the part heart yearn is wound in roller 16 and is driven by roller.
Each part of pivotal arm 15 is shown among Fig. 2.There is pivot bobbin 17 end at pivotal arm 15, and this pivot bobbin has represented to have the part of the connector 14 of bracket arm 13.
In another end, printed circuit board (PCB) 19 is installed on the pivotal arm outer cover 18, on printed circuit board (PCB) 19, has arranged the not detailed electronic component that is used to control monitoring heart yearn 6 that shows.Also contain switch 20 on the printed circuit board (PCB) 19,, turn-off said electronic installation with switch 20 for example through pivot pivotal arm 15.
Said electronic installation element also contains transmitter 21 and the recipient of the optical launcher of the arranged adjacent that for example do not show.Transmitter 21 and recipient are arranged in the corresponding bearing 22 and 23 of pivot outer cover 18, and can observe the spoke 24 of roller 16.Roller 16 also has the run channel 25 of heart yearn 6.
Function of the present invention is following:
For this reason, transmitter 21 emission light, said light is reflexed to recipient from spoke 24.If the only pulsation of being accepted, yarn breakage would not just appear.On the contrary, if only fixing, yarn breakage has then appearred, because light is reflected by spoke 24 enduringly, perhaps there is not light to be reflected fully.
If, then turn-off electronic installation through starting switch 20 in order to check or directed again heart yearn 6 and lift pivotal arm 15.
