More specificantly, the invention is applied for textile industry, especially for yarn treatment machine, e.g. for steaming and beam-like machine for take-up yarns.

Description

Be used to tighten and separate device from the individual yarns of handler

Technical field

The present invention relates to industrial textile, relate in particular to the yarn treatment machine, for example be used to evaporate and tighten the machine of yarn, and relate to and be used for device that the single yarn of leaving handler is tightened and separated from beam or analogue.

Background technology

Knownly to carry out continuous treating process, for example evaporate the yarn that is placed in advance on belt conveyor or the analogue.Therefore,, in the process of evaporating, processed yarn to be placed on the feedway, pass the process chamber that is full of steam or hot gas in coil of wire mode by example.When leaving process chamber, yarn is cooled and is wound subsequently.

When wanting processed yarn to have good mechanical intensity and high linear density,, might handle several one threads simultaneously according to known many yarn treatment process.In this case, processed several one threads to be placed on the feedway jointly in parallel coil of wire mode, and pass and evaporate the chamber, afterwards, they are cooled and twine respectively.This winding realizes that by wrapping head this wrapping head comprises quantity and the common identical winding unit of placing of number of yarns, twines the unit and works simultaneously.

And, when the yarn with good mechanical strength was processed, it was possible twining in the time of the yarn of common placement, and this is owing to can apply enough tension force in the downstream of twining the unit, thereby can separate yarn, and therefore may carry out correct winding all yarns.The device of implementing this process passes through US-A-3638873, US-A-4623101, and US-A-4574574, GB-A-1214999 and US-A-4830296 are disclosed.

When yarn has medium or low mechanical strength and low linear density, owing to have the easier fracture of yarn of low mechanical strength, therefore many yarn treatment process can cause yarn breakage, processing unit is ended fully, and along with yarn breakage, the common yarn of placing stops, thereby causes the obvious reduction of capacity rating, therefore many yarn treatment process is difficult to implement, and even may not implement.

And if yarn is very crisp, it is impossible twining the common yarn of placing simultaneously, and this is so just to have hindered the work of synchronous wrapping head by yarn breakage because the tension force that the downstream of winding unit provides makes.

As a result, the present continuous steaming process that thin and crisp yarn is carried out is usually according to single thread line principle.For this situation, yarn to be processed is placed on to pass on the feedway and evaporates the chamber, and carries yarn to be processed to twining the unit.Therefore, can obtain enough capacity ratings by being arranged in juxtaposition a plurality of processing units.

All this single thread line treating processs all have some shortcomings.In fact, in order to obtain big output, be necessary to implement a plurality of processing units.But when handling very thin yarn, owing to the reason of the mechanical strength of yarn is restricted processing speed, the output of this single thread line processing unit group is obviously reduced.

In addition, the yarn of some types of handling with said method has when the coil of wire when being placed on feedway on leaves feedway towards wind and forms the trend of encircling.As a result, these have reduced the efficient and the quality of twining by the ring that the continuous lines volume of yarn forms.

Summary of the invention

The objective of the invention is to be used to tighten and to separate yarn, make that can control the device that yarn leaves the speed of handler before next step handles yarn overcomes above-mentioned shortcoming from handler by providing a kind of.

For achieving the above object, the invention provides a kind of device, described device is designed to be installed in the machine that is used to handle yarn, for example evaporate and tighten the mouth of the machine of yarn from analogues such as beams, and mainly at least one device of individual yarns constitutes by being used for separately, comprise the individual components that is used to guide yarn, the unit of they being tightened by will independently separating the yarn stretching, and self contained system that is used to detect the yarn existence and regulates yarn speed, thereby make described yarn before downstream, produce relaxing corresponding to the waveform path, the self contained system that is used to the speed that detects the existence of yarn and regulate described yarn mainly comprises and is installed in many to sensor on the supporting bracket, every pair of described sensor is assigned to an one thread that independently separates by the unit of tightening yarn, these to each of sensor to being disposed in the downstream of the pressure roll of introducing cooresponding yarn, and with one be used to monitor and regulate the electronics package co-operating of described stretching from the device of the yarn of downstream machine.

Advantageously, each be used to guide the individual components 2 of yarn 3 to form to be installed in arm 2 ' on the shape of wire loop, arm 2 ' form as one with support 9, extend the upstream of the unit of they being tightened stretching by the yarn that will independently separate.

Described yarn by will independently separate stretches and the unit that they are tightened is formed the shape of at least one nip rolls 10, and nip rolls 10, and are operated every individual yarns with pressure roll 12 is collaborative with constant speed drive by motor 11.Like this, yarn 3 from the upstream process machine can independently be separated well by making their processes distribute to their wire loop 2, subsequently by they are passed between nip rolls 10 and the pressure roll 12, they are pulled out from tensioning rail device of being arranged on upstream process machine mouth etc. with constant pulling force and speed.

Stretch and the unit that they are tightened only is applicable to two one threads 3 that stretch as the exemplary yarn that independently to separate 3 that passes through that illustrates of Fig. 1, Fig. 2, Fig. 4 and Fig. 5.But clearly, this unit can extend widelyer and more pressure roll 12 is set, and the quantity correspondence of pressure roll 12 is from the quantity of the single yarn 3 of the thread layers of handler.

Be used to the self contained

system

4,4 of the speed that detects the existence of yarn 3 and regulate described yarn 3 ' mainly comprise be installed on the supporting bracket 9 many to sensor 4,4 ', each is assigned to an one thread 3 that independently separates by the unit of tightening yarn 3.These to each of sensor to being disposed in the downstream of the pressure roll 12 of introducing cooresponding yarn 3, and with one be used to monitor and regulate described stretching from the

device

groove

42,42 of described sensor ' in.

According to a feature of the present invention, a sensor 4 in the described sensor is disposed near nip rolls 10 and the pressure roll 12, the downstream of pressure roll 12, and, the axis of its element 41 intersects with the path of vertical mode and yarn 3 at the mouth of described nip rolls 10 and pressure roll 12, another sensor 4 of while ' be disposed in apart from first sensor 4-set a distance place, with respect to straight line path one side-play amount is arranged from the upstream yarn of first sensor 4, this another sensor 4 ' be provided be used to guide the described sensor 4 of yarn 3 extend throughs ' and element 41 ' wire loop 13, wire loop 13 is installed in described sensor 4 ' go up (Fig. 1-Fig. 5) by supporting member 14.Then,, be sent to the downstream machine from the yarn 3 of the unit that is used to tighten yarn 3 at described sensor 4 ' afterwards, and by one or several wire loop 15 guiding (Fig. 1).Sensor 4,4 ' the result of skew assembly be when yarn 3 is subjected to certain tensioning between wire-drawing wheel 10 and pressure roll 12 these two elements, yarn 3 have sensor 4 ', the trend (Fig. 4 and Fig. 5) of extending at a certain angle between wire-drawing wheel 10 and the pressure roll 12.

In the embodiment shown in fig. 1, downstream machine 5 is bobbin winolers, the

device

6,6 of drawing 3 ' be have zig-zag roller 6 ' Winder 6.

According to another characteristic of the invention, be used to monitor and regulate the device 6 of described stretching from the yarn 3 of downstream machine 5,6 ' electronics package, can advantageously have the FPGA (Field Programmable Gate Array) regulating control, it has and is belonging to sensor 4,4 ' element 41,41 ' locate detect yarn 3 existence function and detect the function of the speed of yarn 3 from the

device

6,6 of the yarn 3 of downstream machine 5 ' locate stretching.

As Fig. 1-shown in Figure 5, device according to the present invention is operated in the following manner:

Pierced into the wire loop 2 that forms the individual components that is used for guiding yarn from the yarn 3 of a downstream machine, and every velamen is arranged between pressure roll 12 and the wire-drawing wheel 10, and the motor 11 of the unit of they being tightened by stretching by the yarn 3 that will independently separate drives.Then, every one thread pierces into the corresponding recesses 42 of sensor 4, and penetrate subsequently corresponding sensor 4 ' wire loop 13, enter the wire loop 15 of downstream machine 5 then, to enter downstream machine 5, by being used for guiding and carrying out pre-tensioned device 7, arrival stretching device 6,6 '.

In this operation, the mouth of the unit of they being tightened stretching by the yarn 3 that will independently separate, yarn stretches out at the axis direction through the contact point between nip rolls 10 and the pressure roll 12.Make yarn 3 at specified time at last axis with through the deviation post between the axis at the wire loop center at these device mouth 13 places, between these 2 or be waveform, if stretching device 6,6 ' speed be lower than that yarn by will independently separate stretches and the speed of unit that they are tightened; Perhaps be linear, if stretching device 6,6 ' speed be greater than or equal to that yarn by will independently separate stretches and the speed of unit that they are tightened.When the element 41 that belongs to sensor 4 directly extends to the downstream of nip rolls 10 and pressure roll 12, sensor 4 ' element 41 ' directly extend to wire loop 13 before the time, might detect corresponding to existence lax on the yarn 3 in yarn undaform path.For can only bear the very thin and crisp yarn of very limited tensile force the time, this lax be necessary.

If downstream machine 5 is used for the device 6 of drawing 3,6 ' drawing 3 is too fast, for example, as Fig. 2, corresponding the right yarn shown in 4 and 5, the yarn on left side yarn or both sides, have sensor 4,4 ' electronic monitoring and control apparatus send and to be used to regulate the signal of described device 6,6 ' speed, to reduce device 6,6 ' draw speed, thereby make yarn sensor 4,4 ' between take the waveform path, extend like this in this path, the one end enter sensor 4 ' groove 42 ' in, wherein sensor 4,4 ' be formed for detecting yarn 3 exists and regulates the self contained system of described yarn 3 speed.In fact, when yarn 3 is too tight, its two ends all from sensor 4,4 ' groove 42 and 42 ' in shift out and tensioning, as previously mentioned, like this, the existence of yarn 3 one ends can not be by element 41 and 41 ' detect.

Regulated device 6,6 ' speed it is reduced after, make yarn 3 keep constant speeds by the unit of tightening, and form the waveform path that its end is by two sensors 4,4 ' detect according to device of the present invention.When the two ends in the waveform path of yarn 3 were detected, electronic regulating unit sent the end restriction signal, makes yarn be stretched with stable speed, this speed obviously corresponding to this yarn arrive sensor 4,4 ' speed.As a result, can avoid behind the yarn limit tensioning state yarn breakage that may occur behind the state for example shown in Figure 5 fully according to device of the present invention.

According to an alternative embodiment of the present invention, be formed for detecting the sensor 4 of the self contained system that yarn 3 exists, 4 ' can substitute by single multi-region sensor, to detect the diverse location of yarn 3, that is, at least one corresponding to the corrugated position of yarn 3 and one corresponding to slack-free position.This sensor can be for example by the multiposition detector in scanned several zones simultaneously, perhaps even use the detector of doppler principle radar type to constitute.

And electronic regulating unit also may be considered the different stretch speed that yarn 3 can bear, for example, and winding on the taper bobbin (Fig. 1) and the situation of rocking that in winding process, takes place.In these cases, speed of wrap changes, and produces bigger or less stretching on yarn 3.Can consider the variation of these draw speeds according to device of the present invention.

Because the present invention, might be configured for tightening and separating the device of single yarn, make the handler can be with simultaneously treated several one threads separate well in the upstream, and they are tightened individually with constant-tension.This is very useful for tightening very thin and crisp yarn.

And if thin and crisp yarn is handled in many yarns mode in rapid steamer, the problem of the ring that produces in the process of evaporating can be resolved to a great extent.In fact, when by evaporating when thin and crisp yarn handled, be placed the ring that will evaporate and have certain elastomeric trend of maintenance, this elasticity may make and form knot behind drawing, although handle.Owing to can carry out many yarn treatment by device according to the present invention, placement will be evaporated between a plurality of rings, promptly, at least two, even present bigger pitch between 3 or the more rings, since from the replaceable coil of wire of threads, the capability that it has caused described yarn to separate, thus the trend that makes them form ring or knot has been reduced again to a great extent.

Like this, can increase the productive output of upstream process unit according to device of the present invention.

Certainly, the present invention is not limited to the open and shown form of accompanying drawing of embodiment.Under the situation of the scope and spirit that do not break away from claim, can revise structure of the present invention or alternative equivalent technologies.
