Description

For producing the waxing attachment of the weaving loom of cross winding bobbin

Technical field

The present invention relates to a kind of for producing the waxing attachment of the weaving loom of cross winding bobbin, including axially displaceable The wax body being mounted on bear box (bearing housing), in winding process, wax body can be by can be with restriction side The driving device of formula driving is positioned in the waxing plane domain of waxing attachment, and the front end portion of wax body reclines in this region On the yarn of operation.

Background technique

In textile machinery industry, waxing attachment has been used for a long time, especially with regard to production cross winding bobbin Weaving loom.Waxing attachment can be configured in many different ways, also there is related specific description in the patent literature.

It is used to produce the weaving loom of cross winding bobbin known to this known waxing attachment, mainly in winding process The middle coefficient of friction for reducing yarn.That is in the low capacity coil rewinding Cheng great Rong that ought be usually produced on ring spinner During the cross winding bobbin of amount (such as executing in so-called intersected coiled bobbin handset), the particle of wax is applied to yarn The operation and anti-friction performance of yarn can be improved on line, this is especially relevant with the next production phase in process of production, Such as when braiding or knitting.Alternatively, waxing attachment may be provided at the upstream of the winding device of rotor spinning machine.

This waxing attachment for having relevant detailed description in such as CH706608A2 or DE4010469A1 includes wax Body, in order to realize the uniform loss of wax body as far as possible, wax body is slowly rotated along its longitudinal central axis line and at the same time in yarn The direction of operation carries out axial pressure by load device.That is this waxing attachment contacts fortune with their wax body end Wax is simultaneously applied on yarn by capable and traversing yarn in this way.

For move wax body, be mounted on drivable bearing axis the fixed but axially displaceable load device of rotation It may be designed to different patterns.

Coil spring is for example used as load device in CH706608A2, and wax body rear is arranged on bearing axis Coil spring axially applies pressure to wax body on the direction of moving yarn.

A kind of load device that can be compared is also disclosed in DE4010469A1.In the known waxing attachment, wax body It is pressurizeed by additional load beam, load beam bears the spring effect of prestressing force flexural spring again in turn.Herein, wax body It is configured to continuously contact the yarn of operation.

In waxing attachment known to these, the operating position of wax body can also be carried out by adjustable motion limiting mechanism It limits in advance, that is, waxing plane can be determined by the looping angle of yarn, to obtain the waxing of more or less degree Amount.

Such waxing attachment also generally includes the sensor device used for monitoring wax body, that is, is filled by sensor It sets, which indicates when that the wax body for rotating installation about rotary shaft has arrived at minimum dimension and needs to carry out more It changes.

(it is being revolved from being supported by below the load device of such as rod-type in the waxing attachment according to DE4010469A1 In the wax body turned) equipped with using permanent magnet as the emission element of form.

In addition, in this known waxing attachment, sensor element, such as Hall sensor, it is located in fixed guarantor It holds on device.

If the emission element of load device due to wax body abrasion and when further being guided to fixed sensor element, The close magnetic field that monitors they of the Hall sensor because of magnetic element.By electronic switching device immediately or delay one section when Between after generate for request replacement wax body information signal, wherein the switching device be adjusted for processing information signal so that Winding process stops perhaps just stopping or only pass through after the remaining runtime of 10min to 240min visually to fill at once It sets and is presented to operator.

The visualization instruction of this remaining runtime has the disadvantage that is, operator usually also needs manually to determine first Each practical also how many runing time of individually work station is available.That is, checking which works for operator Station, which needs most the replacement wax body before work station is by forced-stopping machine, certain difficulty.

In order to more accurately determine the remaining runtime of wax body, the past proposes in DE4226265A1 a kind of uses number The method that method determines the remaining time of wax body.That is, in known wax body device, dress of the wax body in suitable design It is movably mounted in setting along the feeding axis transverse to yarn operating path, is constantly reduced because of yarn contacts in this way Wax body reach minimum dimension and be instructed to out so that passing through the ginseng such as wax body weight, wax amount abrasion loss, yarn count, winding speed Number determines that wax body reaches the expection runing time before minimum dimension by calculating.

In order to determine waxing attachment wax body remaining runtime, also proposed in DE102013018877A1 upper Two exploring blocks are installed, first exploring block is fixedly disposed relative to rotation axis, second probe portion in wax apparatus Part is arranged in wax body or on the holder of wax body, so that on the one hand second exploring block can be rotated around rotation axis, On the other hand it can be shifted along rotation axis.That is two exploring blocks are by wax body along the linear motion of rotation axis Successively it is overlapped.

The known waxing attachment being widely used in practice not only in the accurate remaining runtime of determination some Problem, while in known waxing attachment, excessive wax is often applied on moving yarn, this is also a problem. That is in order to ensure yarn waxing under any circumstance is abundant, these known waxing attachments are usually with excessive yarn packet It twines angle and excessive wax applied amount works.

Since the wax particles that yarn be run, traversing is removed from wax body generally can not attach to yarn sufficiently solidly Line, thus this waxing attachment not only result in wax amount using it is excessive and after one relatively short time can make dirty Wax apparatus.Further, since gravity and often especially usually have on the part for the associated station being set to below waxing attachment Too many dirt.

It is related to waxing attachment above-mentioned, therefore the wax body that rotation is set in fixed cover is also had been proposed that in the past Or catch tray, the Wax particles of yarn entrainment rubbing off in this way, not being run at least are installed in the lower section of wax body It is collected.

Such as a kind of collection vessel for being equipped with the wax particles for falling is disclosed in DE102005028751A1 Waxing attachment.

Most known waxing attachment does not comprise only the shortcomings that unnecessary high wax consumption yet, and these are The further disadvantage for the waxing attachment known also resides in after replacing yarn batch, when being basic with the thread material newly provided Need to adjust waxing condition, this always needs to undertake one, and very troublesome and time-consuming wax body backstop be again Adjustment.

This means that any change for utility ratio of waxing always needs the yarn in wax body in known waxing attachment The change of looping angle, and the therefore position correction of wax body backstop.

Therefore, a kind of waxing dress for producing the weaving loom of cross winding bobbin is proposed in DE102014012247A1 It sets comprising propped up during operating winding the front end portion of the wax body being axially movably mounted in bear box, wax body In the region for supportting the so-called waxing plane on the moving yarn of work station.Bearing of the waxing attachment in waxing attachment So-called waxing hole is provided in the front end area of shell, the yarn run in this way passes through fixed foundation ring (loop) continuity Ground guidance.

In addition, the waxing attachment has feeding unit, allow wax body adjustable, limit on the direction in hole of waxing It is fixed axially displaced and carried out by two sensing devices.

First sensor is arranged in the region of rear portion connecting plate of the bear box of waxing attachment, thus monitors stepping The rotation angle of motor, and the detection corresponding virtual condition of wax body of the second sensor in the region of front connection plate is set.

Summary of the invention

Based on the aforementioned prior art, potential purpose of the invention is to create a kind of waxing attachment, wherein on the one hand ensuring It avoids any undesirable wax abrasion as best one can in operating winding, on the other hand also ensures that moving yarn can always sufficiently Waxing.

The purpose is reached by a waxing attachment according to the present invention, which, which has, is connected to workstation computer Sensor device or sensing system, whether the front end portion of monitoring wax body is located in the waxing plane of waxing attachment In region, and if the front end portion no-fix of wax body in the region of the waxing plane of waxing attachment, workstation computer It is designed to correct the feeding rate of driving device.

Particularly, embodiment according to the present invention this have the advantage that by using the sensing for being connected to workstation computer Device device or by using the respective sensor system for being connected to workstation computer, may be with relatively easy and reliable side Whether the front end portion that formula continuously to monitor wax body is accurately aimed at moving yarn.This means that sensor device or sensor system Whether the front end portion (as needed for the best applications for waxing) of the continuous monitoring wax body of system is located at the institute of waxing attachment It is pressed against on moving yarn in the region of the waxing plane of meaning and therefore with a scheduled contact pressure.If having assert wax The front end portion of body is not in the region of waxing plane, and workstation computer ensures that the driving feeding rate of wax body obtains more Just.

The front end portion of wax body, which is located in, does not only result in optimal upper of yarn in the so-called waxing plane domain of waxing attachment Wax, and also ensure minimal amount of unnecessary Wax particles in wax body by being arranged in such a way wax body and be worn.

According to an advantageous embodiment, sensor device includes transmitter and receiver, and opposite two of wax body are arranged in they Side, so that when the front end portion of wax body is located in the region at the waxing plane rear of waxing attachment in feeding for wax body on direction When, receiver cannot receive the control light beam that transmitter is launched, and sensor device then generates signal.

Pass through the region that will not be inadvertently arranged in other than waxing plane this design ensures the front end portion of wax body In, it will lead to the contact too strong with moving yarn in this way and then lead to the unnecessary high abrasion of wax body.Pass through embodiment above-mentioned Meet the precondition for needing the moment economically to operate waxing attachment.

In an advantageous embodiment, workstation computer is designed to, under the signal input condition of sensor device, just It is intervened for " the feeding rate of limitation driving device ".This means that if sensor device has determined the front end portion of wax body Through entering the region other than waxing plane, workstation computer is corrected the feeding rate of the driving device of wax body at once and is ensured The front end portion of wax body moves back in the region of waxing plane.

In a further advantageous embodiment, workstation computer is designed to, if do not had within a preset time period There is signal to be input to workstation computer from sensor device, ensures that the feeding rate of driving device improves.This means that After a special time period, the signal deletion of sensor device is read as meaning the front end portion of wax body by workstation computer It is located in the region in front of waxing plane relative to wax body feeding direction and therefore moving yarn does not have with the front end portion of wax body There is any contact.

In order to change yarn not by this very adverse conditions of waxing, workstation computer ensures the driving of wax body immediately The slight growth of the feeding rate of device, it means that the front end portion of wax body after a specific, relatively short period again It comes back in the region of waxing plane and therefore guarantees the best applications waxed in moving yarn.

By the previous embodiment of waxing attachment, it is opposite can not only to ensure that wax body has in a relatively simple manner Longer service life, and can guarantee that yarn can continue correctly to wax.In addition, the embodiment described cause it is very compact Structure, which can not only be installed on waxing attachment easily, and it is very reliable and accurate to operate.

According to further advantageous embodiment, sensor device or sensing system, as provided, according to optical barrier (light barrier) principle is operated.

This means that the optical barrier in optoelectronic areas is a kind of interference for identifying light beam and with the mode exhibition of electronic signal Reveal the system come.

Since optical barrier is not only without frayed and therefore durable, but also the components being mass produced can relatively just It preferably obtains, therefore is very favorable device according to the sensor device or sensing system of optical barrier principle operation.

In an alternative embodiment, using a kind of sensing system comprising first transmitter and acceptor device and Second transmitter and acceptor device, they relative to wax body feeding direction it is axially spaced apart from each other be provided separately, and connect To workstation computer.This means that first transmitter and acceptor device and second transmitter and acceptor device are with respect to that This ground setting that axially offsets, so that when the front end portion of wax body is positioned in the waxing plane domain of waxing attachment, the first hair The controllable light beam of emitter and acceptor device is blocked by wax body, and first transmitter and acceptor device correspondingly generate signal, and It sets up second transmitter in rear region in the waxing plane of waxing attachment in the feeding side of wax body simultaneously and connects The controllable light beam for receiving device device is not blocked and therefore generates without signal.

This means that for the computer of work station, the signal input of first transmitter and acceptor device and same with this When the signal from second transmitter and acceptor device missing show wax body be properly positioned to waxing plane region in And the feeding rate of the driving device of wax body need not be corrected.

However, if workstation computer also has received in addition to the signal from first transmitter and acceptor device simultaneously Except the signal from second transmitter and acceptor device, workstation computer recognize wax body front end portion be located at it is upper Region other than the waxing plane of wax apparatus simultaneously ensures that the feeding rate of the driving device of wax body slightly slows down and before wax body End part positioning returns in the region of waxing plane of waxing attachment.

When the first and second transmitters and acceptor device all do not have signal, this shows either first transmitter and connects The control light beam or second transmitter of receipts device device and the control light beam of acceptor device are not all blocked by wax body, because of wax The front end portion of body is positionable relative in the farther away region of waxing planar front portion of waxing attachment, and workstation computer is accordingly true The feeding rate for having protected the driving device of wax body slightly increases and therefore the front end portion of wax body correctly comes back to waxing In the region of plane.

In further advantageous embodiment, workstation computer is designed to make data (its of sensing system Effective feeding rate from the controllable driving device for wax body) can by measuring technique by workstation computer into Row monitoring.

Preferably, workstation computer can handle by measuring technique monitor from controllable driving device The effectively data of feeding rate are possible to determine the waxing behavior of waxing attachment during bobbin moves in this way.

It can determine that for example adjustment waxing utilization rate is desirable.

Waxing utilization rate this change can realize for example by correcting the feeding rate of the driving device of wax body, wherein Feeding rate can be for example adjusted on workstation computer and/or weaving loom central control unit.

Setting feeds rate on workstation computer and setting feeding rate is equal on the central control unit of weaving loom It is beneficial, wherein setting feeding rate is very favorable in the central processing unit of weaving loom, this is because working as multiple works Make station to need while the time can be saved when adjusting to a new feeding rate.

The conclusion obtained from the waxing behavior of waxing attachment during bobbin movement can also be with the material of used wax body It is related.Such as can also suggest, the wax body with slightly different upper wax material is used in next winding process.

It is also required to monitor possible yarn defect from the yarn 16 that coil 3 is extracted out during re-winding, yarn defect is more than predetermined threshold It will be removed when value.

The yarn 16 of operation is also usually waxed during re-winding.

This means that the yarn 16 of operation is guided on the waxing attachment 19 in the region for being arranged on thread path, this Sample ensures that the coefficient of friction of yarn 16 reduces and therefore the operation of yarn 16 and anti-friction performance greatly improve.

Corresponding waxing attachment 19 including sensor device 40 or sensing system 50 is with reference next to Fig. 2 to Fig. 5 It is explained in greater detail.

The cross winding bobbin 5 produced usually is transported to machine by the service unit that (not shown) is automatically brought into operation The cross winding bobbin transport device 7 of length and by the cross winding bobbin transporting apparatus transports to being arranged in machine end Bobbin loading depot or similar device.

Also shown in FIG. 1, this intersected coiled bobbin handset 1 is usually also equipped with bobbin and bobbin transportation system 6, wherein Coil 3 or bare bobbin rotate on disc transport 11.

Fig. 1 merely illustrate this bobbin and bobbin transportation system 6 bobbin feeding part 24, can reverse driven storage part 25, it guides to one of axial transport part 26 at winding station 2 and bobbin returning part 27.

Single work station 2 also has different operating devices, may insure this work station 2 just by these operating devices Really operation.This operating device is in professional domain by the known some time, therefore these schematically show in Fig. 1.

One of them known device is, for example, winding device 4 comprising around the bobbin cradle of 12 activity installation of pivot axis 8。

According to the present embodiment, the cross winding bobbin 5 being mounted on bobbin cradle 8 during winding process is located at its surface In driving roller 9, and friction carrying is passed through by the driving roller 9 that the individual motor drives.The driving device of driving roller 9 33 are connected to workstation computer 28 in this case through control line 35.

For the traversing of the yarn 16 run during winding process, a kind of yarn transversing mechanism 10 is additionally provided.The yarn Line transversing mechanism 10 (only suggesting illustratively in this embodiment) has such as Yarn guide device 13, the Yarn guide device With finger-like yarn transmission pole.

During winding process, the yarn transmission pole that can be controlled by electro-mechanical driving device 14 is in cross winding bobbin 5 Two end sides between make 16 traversing of moving yarn.The driving device 14 of Yarn guide device 13 is in this case also by control Line 15 processed is connected to workstation computer 28.

Yarn transversing mechanism 10 can certainly be designed different.The traversing of yarn can also be guided for example by yarn and be rolled Cylinder or the traversing Yarn guide device by guiding in the yarn roller of reversed (inverted) are realized.

As described above, before the work station 2 of this intersected coiled bobbin handset 1 generally includes to be located at yarn transversing mechanism 10 tightly Waxing attachment 19 in the thread path region of side, the waxing attachment make that wax is applied on yarn 16 during winding process It is possibly realized.

It (especially shows to become apparent from Fig. 2 and Fig. 5 in detail) as shown in Figure 1, waxing attachment 19 also has driving device 34, which is connected to workstation computer 28 via control line 37, and the workstation computer is further through machine bus 17 It is connected to the central control unit 44 of intersected coiled bobbin handset 1.

Fig. 2 and Fig. 5 is shown with perspective view and greater proportion with designed according to this invention and arrangement sensing respectively The first embodiment of the waxing attachment 19 of device device 40.

As shown in Fig. 2, waxing attachment 19, such as (not shown) are fixed on the spinning station of work station 2 by mounting device On shell, including the bear box 30 with rear end terminal pad 18 and front end terminal pad 29.In rear end terminal pad 18 for example by means of Bolt 45 is helped to be fixed with driving device 34, which is preferably the form of stepper motor, and driving device is via control Line 37 is connected to the workstation computer 28 and/or central control unit 44 of intersected coiled bobbin handset 1.

Particularly as shown in figure 5, thread spindle 20 is connected to the motor shaft of the stepper motor 34, thread spindle for example passes through spiral shell Line part 21 is connected to feeding trolley 22, is designed to that the wax body 23 of piston-shaped is mounted in traverse feed trolley 22.

Trolley 22 is fed for example by being mounted to guide device 39 shown in section in 30 inner shaft of bear box To displacement.This means that feeding trolley 22 can be by stepper motor 34 for example, by rotating thread spindle 20 on the D of direction of rotation And the square upward displacement on feeding direction R, i.e., in so-called waxing plane PE.

As shown in Figure 2 and Figure 5, front end terminal pad 29 is bent forward compared with lower part preferably 90 ° and therebetween part at it It include central Yarn guide device 38, the yarn 16 of operation draws in the center Yarn guide device during winding process It leads.

It is also equipped with bearing disk 31 in the region of the front end terminal pad 29 of bear box 30, is equipped with upper end yarn slippage Part 32 and side yarn limiting mechanism 36.

In addition, being provided with sensor device 40 in the region of front end terminal pad 29, such as it is connected to associated station 2 Workstation computer 28.

The sensor device 40 has transmitter 41 and receiver 42, and as shown in Fig. 2, Fig. 3 and Fig. 5, they are arranged to make The control light beam 43 that be issued by transmitter 41 is run in the region slightly rearward so-called waxing plane PE of waxing attachment 19, And it is not blocked during winding process when the front end portion of wax body 23 46 is properly positioned in the waxing region plane PE.

It means that if the front end portion 46 of wax body 23 is properly positioned the region of waxing plane PE (in the region The front end portion 46 of interior wax body 23 is sticked on the yarn 16 of operation with predetermined contact pressure), sensor device 40 would not produce Raw signal i.

If the front end portion 46 of wax body 23 removes the region more than waxing plane PE, wax body 23 is covered according to optical barrier The control light beam 43 of the sensor device 40 of principle operation, as a result, sensor device 40 generates signal i.Signal i then by The processing of workstation computer 28, so that workstation computer 28 ensures that the feeding rate of obvious slightly higher stepper motor 34 is omited It edges down low.

The front end portion 46 of wax body 23 is during winding process unexpectedly far from 16 certain distance of moving yarn in order to prevent It positions simultaneously so that moving yarn 16 is no longer waxed, workstation computer 28 works according to below step:

If no longer generating signal i by sensor device 40 within certain, the preset period, this often means that, Since the feeding rate of stepper motor 34 is a bit too low, the front end portion 46 of wax body 23 more or less status on feeding direction R In the front of the waxing plane PE of waxing attachment 19, that is, be spaced away from moving yarn 16, workstation computer 28 ensures to walk Feeding rate into motor 34 increases again immediately, and therefore the front end portion 46 of wax body 23 correctly returns to waxing plane PE Region in.

Fig. 4 shows another embodiment of waxing attachment 19 according to the present invention.This means that substituting in this embodiment Sensor device 40 installs sensing system 50, is connected to the workstation computer 28 of associated station 2.

In the front of waxing attachment 19, the first transmitter and reception that there is sensing system 50 axially spaced-apart to be provided separately Device device 51A, 52A and second transmitter and acceptor device 51B, 52B, they are respectively connected to workstation computer 28.

Thus waxing attachment 19 is arranged in transmitter 51A and receiver 52A on the feeding direction R of wax body 23 waxing is flat The front of face PE, and the rear of waxing plane PE is arranged in transmitter 51B and receiver 52B on the feeding direction R of wax body 23.

This set means during winding process in conjunction with the corresponding software in workstation computer 28, is working as wax body 23 it is properly positioned that (wherein the front end portion 46 of wax body 23 is located in the region of waxing plane PE and therefore with slight operating pressure It is pressed against on the yarn 16 of operation) when, the receiver 52A in front of waxing plane PE is set and is sheltered from by wax body 23, so that by The control light beam 53A of transmitter 51A excitation can not be detected by receiver 52A, and then generated signal i and be sent to work station Computer 28.

At the same time, the receiver 52B that the rear of waxing plane PE is arranged on the feeding direction R of wax body 23 is detected The control light beam 53B of transmitter 51B, the result is that being generated without signal i.

This signal input, which interpret by workstation computer 28, means that the front end portion 46 of wax body 23 is correctly fixed Therefore position need not simultaneously correct feeding for the driving device 34 of wax body 23 at the moment in the region of the waxing plane PE of waxing attachment 19 Enter rate.

If occurring the mistake displacement of wax body 23 during winding process, that is, if the front end portion of such as wax body 23 46 are pushed into more than waxing plane PE on feeding direction R, then wax body 23 blocks transmitter and acceptor device 51B, 52B, this Sample transmitter and acceptor device 51B, 52B generate signal i.

The signal i of transmitter and acceptor device 51B, 52B are then correctly interpreted so that wax body by workstation computer 28 The feeding rate of 23 driving device 34 is slightly excessively high.Workstation computer 28 ensures feeding for the driving device 34 of wax body 28 accordingly Entering rate slightly reduces.

If workstation computer no longer receives signal i during winding process, because regardless of first transmitter and reception Device device 51A, 52A or axially spaced second transmitter and acceptor device 51B, 52B are not blocked by wax body 23 Firmly, what 28 solution of workstation computer was read is to mean that the feeding rate of the driving device 34 of wax body 23 is too low.

In this case, workstation computer 28 ensures that the feeding rate of the driving device 34 of wax body 28 slightly increases Long, the front end portion 46 of such wax body 23, which positions, to be returned in the region of waxing plane PE.

The use of sensing system 50 allows that the workstation computer 28 accordingly designed is combined to realize to by effectively feeding speed The data that rate obtains are recorded by measuring technique.

The conclusion about the waxing behavior of waxing attachment during bobbin moves then can be simply obtained from the data, The feeding rate of its driving device 34 that can be used for for example more preferably being arranged wax body 23.
