Abstract
A kind of method of the involute winding yarns in underwinding district in order to the spindle that has pattern at the yarning part as ring spinner, yarn is guided with the form of wave in the underwinding district.
Description
The present invention relates to a kind of on for example for the underwinding district of the stator that has pattern in the yarning part of ring spinner coiling method of yarn and device.
After being rolled up thread layers at the ring spinner middle bobbin is example, is necessary this bobbin is removed from the spindle of corresponding yarning part, changes a new bare bobbin.At present, this process is normally full-automatic, to this new bobbin starting spinning, does not need the staff to operate usually, promptly must pull apart yarn when full removing, but this yarn must be in when new bobbin begins to spin simultaneously again and to prepare the position.It is achieved in that usually promptly that after finishing a complete thread layers ring rail of guiding yarn descends, so that can three to five yarns doff be wound up on this spindle with low speed in the underwinding district that is arranged in below the bobbin.When removing the bobbin that has complete thread layers, between underwinding district and full bobbin, pull apart this yarn.
After yarning part was reset, ring rail rose again, and thus, the rotation of spindle will make yarn be wound up on the bobbin.After yarn began to be wound up on the bobbin, the yarn pitch of the laps in the underwinding district just became unnecessary.But, yarn extends upwardly to bobbin from the underwinding district, and forms the pitch of the laps of the package innermost layer on the bobbin in winding process.
If the pitch of the laps in the underwinding district is not removed, they just stay the there always.Pitch of the laps is just piled up in the underwinding district as a result, causes being difficult to remove.For this reason, many measures had once been developed in the past.For example brush away the pitch of the laps outside the underwinding district by hand.But do like this and just produced a large amount of interference flyings.If a plurality of spindles are all handled like this, will produce " snowstorm " of flyings.Can cause that so whole spinning machine breaks down.In addition, manual elimination cost is higher, and needs the plenty of time.
Above the underwinding district, the parts of " underwinding crown " are arranged usually.It normally is made up of two toothrows, and this two toothrow makes original vertically yarn of guiding transfer along ingot axle circumferencial direction and guides.On this part of this ingot axle, provide with a groove a few circle pitch of the laps of reeling on it.
For example, German patent DE-PS2,931,209 knownly have a kind of method of yarn that is used to remove on the underwinding position in ring spinner or double-deck ring spinner, in this method, pull apart yarn with the underwinding remover.The end of a thread is presented so that carry out separating action with the air-flow of air blast.This method and corresponding device thereof not only complexity but also costliness, because additionally need compressed air at the yarning part place, and compressed air causes the flyings of fiber in the machine to increase.
German patent DE-OS3,622, the 561 known devices that a kind of clamping yarn and thread head is arranged.This device also matches with the yarn clipper.Its fixture has a plurality of ridges on circumference, and these ridges have good purchase capabilities.These ridges for example can be staple fibre or brush.
The shortcoming of said apparatus is that pitch of the laps also will be attached on the ridge, and they still will be removed by hand every now and then.
The objective of the invention is to develop a kind of in the underwinding district of spindle coiling method of yarn and device.Not only overcome above-mentioned defective at method and apparatus of the present invention, and utilized this device of the present invention to make that not only the pitch of the laps number of reeling in the underwinding district is minimum, and can also remove the pitch of the laps in the underwinding district effectively automatically.
The objective of the invention is by in the underwinding district, reaching with the form directing thread of wave.
In the advantage that has with the form directing thread of wave in the underwinding district be: in the underwinding district as long as settle a loop yarn wire-wound circle promptly enough.But must to make the form of tool wave be cranky form to this pitch of the laps.Owing to increase the contact site of pitch of the laps and spindle pattern in large quantities, make the adhesive force of the yarn pitch of the laps in the underwinding district increase greatly.Or else the yarn pitch of the laps must become several enclosing the land to guide, with the form of wave around enough once enclosing.
At one preferably among the embodiment,, reach the form coiling of yarn with wave by selected spindle pattern itself.For reaching this purpose, will correspondingly dispose pattern, will be described in detail below.Also the form that can produce the wave of yarn by the motion of yarn is reeled, and can utilize ring rail to reach this result several times together with pumping of rings and steel traveler thus in ring spinner.But, this method energy loss is higher.The third method is made up above-mentioned two kinds of methods, be about to pattern and be designed so that yarn can be with the form guiding of wave, and this wave is produced by the rising and the decline of ring rail.
Preferably among the embodiment, the underwinding district is furnished with a special butterfly crown one of the present invention.This butterfly crown provides with desirable pattern.
In one case, this pattern can be made up of engaging tooth.This engaging tooth is configured to a kind of wedge-shaped slot.Yarn just is placed in this groove.This engaging tooth forms in such a way, makes yarn form by wave in groove be guided.Yarn repeatedly imbrication in the limit of this engaging tooth, thereby the increase of frictional force is occurred on those positions that grip yarn in this groove especially.As long as the yarn of a pitch of the laps is just enough, for example, to remove in the process of full fitted tube pipe, this yarn pitch of the laps or be pulled away is if this pitch of the laps falls in groove just perhaps yarn is pulled apart then.But also no longer need the servo operation of any craft.
Butterfly crown or can be made of one, or formed by similar last crown and following crown, and each tooth of time crown is engaged in down between each tooth of crown.This depends on how crown is processed.
Adopt the method for a kind of disc butterfly crown as the combination of the ascending motion of implementing above-mentioned a certain pattern and yarn.Angle with many directing threads is provided on the surrounding edge of this crown, and this angle provides as mentioned above in order to increase the limit of frictional force.In order to guarantee directing thread in angle, be necessary that directing thread is reciprocating in circumferential edge.This can be by realization that ring rail is correspondingly promoted or lowers.
The another kind of selection is a kind of applied in any combination at a known underwinding crown and butterfly crown.These in addition can only make by a single part, thus, at least one toothrow of underwinding crown is the periphery top that is configured in the butterfly crown.Yarn is just more reliable basically in the insertion of the between cog of spiral shell shape crown.
This simple measure reduces waste of yarns greatly, and has reduced the fiber flyings in the ring spinner, because have only a loop yarn line to fall at most from the underwinding district.
Other advantage of the present invention, characteristics and details will be below embodiment and accompanying drawing in introduce.
