Abstract

PURPOSE: To avoid less efficiency by braking a cross-wound package at rest during occurrence of a yarn defective portion, cutting yarn thereafter to remove the yarn defective portion and forming a knot or splicing joint to start winding. CONSTITUTION: When a yarn monitor 10 detects that a defective portion occurs in running yarn 3, a controller 43 turns off a motor 25 and actuates rapid braking devices 50, 51 to put a winding drum 12 and a cross-wound package 14 at rest. After they are at rest, the yarn 3 is cut by a yarn cutter 9, the yarn defective portion is removed, a knot or a splicing joint is formed instead of the yarn defective portion and then the braking devices 50, 51 are released to start the motor 25 for winding operation. In this way, the less efficiency of an automatic winder due to the occurrence of the yarn defective portion is minimized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Separation for use on K-strips] The present invention monitors the running yarn in the winding section of a textile machine that winds a twill package, detects and removes each yarn defect site, and separates the knots or A method of forming a splicing joint and thus winding a defect-free cheese package, and a winding unit for carrying out the method.

[Conventional 19-Yet Winder] It is known that an automatic winder monitors a running yarn and detects and removes defective portions of the yarn.

The thread cleaner or thread monitor generates a cut signal or automatically interrupts an uncut signal. The threads are then rejoined by means of knots or splices, so that for this purpose the lower and upper threads which have been separated by the cutting of the defective region must first be retrieved once again.

In this case, various difficulties arise, especially when locating the upper thread. This is because the upper thread is wound onto the twill packaging and, if necessary, during a very long inert rotation of the twill packaging, the upper thread is wound onto the surface of the twill packaging.
This is because they can be pushed inside and are often unsearchable.

As a result, the twill package cannot be wound with a last trench, or at least the end of the upper thread must be manually located and prepared for delivery to the thread binding device.

This means that the weight is not fixed, that the automatic winding operation is severely hampered, and that the efficiency of the automatic winder is reduced.

[The problem that the invention attempts to solve]

The object of the invention is to create the preconditions for an automatic winding operation to be carried out without any disturbances.

[Method for solving the problem] The structural means for solving the problem is to automatically control the twill package in the shortest possible time by strong immediate braking when a yarn defect site occurs. the thread is brought to rest, avoiding interruptions of the thread, and only after the rest the thread is separated, the thread defect is removed and a knot or splicing joint is formed in its place, respectively, and then the winding operation is carried out without delay. The point is to restart the.

[f'l-width]

Although the yarn defect site is not immediately eliminated according to the invention, this is only a superficial drawback, and only to such an extent that it is again satisfactorily offset by the advantages.

The yarn defect area is wound onto the final package cage, but
can be removed with great certainty. This is because the time during which the twill package is at rest is so short that only a very small length of thread can run over the twill package during this short period of time. Since the yarn is uninterrupted, automatic unwinding from the package cage is trouble-free and quick. The needle thread does not have to be searched first; it is already present at the predetermined location. That is, do you first pick off the uncut part and then unwind and remove the defective part of the yarn, or do you not cut the yarn beforehand and first pull back the defective part by unwinding and then remove it? Regardless of the situation, the upper thread is already present in a specific area and has one stitch.

[Method] Advantageous Hinoki J5L・ In the present invention, after the twill package has come to rest, the thread is divided into a bobbin thread and an upper thread, and the upper thread wound on the twill package is then automatically wound. After a predetermined unwinding time has elapsed or after a predetermined thread length has been unwound, the unwound thread portion is cut and removed, and then the bobbin thread and needle thread are automatically squarely joined without delay to perform the winding operation. It is advantageous to restart or resume.

Rewind time is limited by full time relay.
be able to. In that case, the experience points obtained from the experiment will be used as a bonfire. Moreover, it must be ensured that the defective yarn can be unwound from the twill package during the predetermined unwinding time.

In that case, a renewed cutting operation removes the thread section with the thread defect site, and after this removal the upper and lower threads are recombined in a customary manner. During unwinding, it is possible to suction the thread into a suction nozzle, which can also receive the cut thread parts and transport them by means of suction air to the waste collection section.

According to the present invention, it is possible to further shorten winding interruptions by selectively or additionally performing the following operations.

After the twill package has come to rest, the thread unwound onto the twill package is automatically unwound, with the thread being guided along a sensor which detects the yarn defect site. When the sensor itself detects a yarn defect site, operations are automatically initiated without delay to remove the yarn defect site and squarely join the yarns. In this case, unwinding can also be carried out while the yarn is uncut or after it has been uncut.

For example, the sensor f'1f11 may be installed in the tube that receives the yarn during unwinding. However, the sensor may also be the same as the sensor that continuously monitors the yarn during normal winding operations.

[Apparatus means for solving the problem] The present invention provides a defect-free cheese-wound package winding apparatus that sends out a defect signal and includes a yarn monitor, a yarn cutter, and a yarn joint forming device, and A fiber tightening machine for carrying out the method, comprising a control device connected to a drive device for the twill/ξ cage, the yarn monitor, the yarn cutter, and the yarn joint forming device by control conductors. According to the present invention, the drive and/or bearing of the twill package is provided with at least one rapid braking device connected to said control device, so that said control device is capable of detecting defects. Automatically turns off the drive device when a signal is input
F or electrically braking the rapid braking device to bring the cheese to a standstill. It is characterized by the presence of

According to the invention, the device for unwinding belongs to the device for removing yarn defects.

[Advantageous configuration on the device]

In the case of rapid braking, the winding tube of a high-mass cheese-wound package slips on the surface of the winding tube receiver, with the result that all the drives of the winding tube are destroyed or already stopped, even if they are braked by the housing. It often happens that the winding tube still does not come to rest.

In order to avoid this problem and the disadvantageous consequences thereof, in the present invention, the interlocking of the package winding tube by means of a mere frictional connection is abandoned, and instead the package winding tube is interlocked between the package winding tube and the bearing. There are interlocking teeth that prevent the winding tube from slipping along the tube receiver.

In an advantageous embodiment of the invention, the control device has a time relay activated by the fault signal, which time relay has an active connection line leading to the thread binding device and/or the thread cutter.

A time relay actuated by a fault signal has a switching contact which switches after a settable period of time and optionally also switches after a further set period of time to prevent the departure of the horn. Return to state. When switching the changeover contact, for example, the thread cutter and the thread bond forming device are switched ON, in which case the thread cutter is only briefly turned on by means of the wiper contact.
is turned on in a pulse-like manner, and immediately switched to the angle 0"F.On the other hand, the thread joint forming device is normally activated before the threads have been joined. Additionally, the time relay can automatically switch back to its original starting position.

Furthermore, it is advantageous according to the invention to provide an unwinding device connected to the control device, which has a sensor arranged in the unwinding yarn path and detecting yarn defect sites. Furthermore, the control device is wired to automatically stop the rewinding device upon input of a sensor signal of a rewinded yarn.

A prerequisite in this case is that the rewinding device is switched off immediately after the response of the sensor. The unwinding device has, for example, a special unwinding motor, to which a friction wheel transmission is connected, the friction wheel of which can still be connected to the cheese package. But again,
The rewinding device may consist of a switching device for switching the main motor into a reverse gear. The drive motor is then advantageously used in four-quadrant operation.

It is also possible to do without a housing rewinding device. That is, if the yarn defect site is detected a few tesi meters upstream of the twill package and then the twill package is brought to rest very quickly, the yarn defect site may be
When the twill package cage is at rest, there may be no lint on the twill package. In such a case, it is sufficient to activate the yarn defect removal and yarn recombination device after a very short delay time after inputting the first defect signal.

[Actual Mh example]

Next, one practical example of the present invention will be explained in detail based on FIG.

FIG. 1 shows a winding station 2 in a spinning machine 1 for winding cheese packages, which is configured as an automatic winder. The spinning machine 1 can operate a large number of winding sections of the same type.

In the winding NS2, the thread (yarn) 3 is paid out from the payout bobbin. In this case, the feed-out pobbin has the shape of a spun spun by a front spinning machine. Thread 3
The yarn travels in the direction of arrow 6 via the balloon breaker 5, passes through the yarn guide member 11 and the winding drum 12 of the yarn package drive 13, and is wound as a cheese package 14 forming a winding sheet. be done.

The traverse movement of the thread 3 within the traverse linkage triangle 15 is effected by a reciprocating thread guide (not shown).

As usual, the yarn package is supported by a pivotable bobbin frame, which pivots upward as the yarn thickens. The bobbin frame has one winding tube receiver on each side, as is customary. The two tube receptacles usually rest in a friction-locking manner on both ends of the package tube. The winding tube receiver defines the package winding tube and thus the package, and is rotatably supported by the bobbin frame.

Although it is only hinted in FIG. 1 to make it easier to see around the park, the mounting mandrel 6 for the twill package 14 is supported on a vertically movable support 17, which is different from the conventional package support system. Then, the support can be lifted from its initial position by the twill and ξ hook lifter 18 to release the grinding contact between the twill package 14 and the winding drum 12.

It is also possible to equip a similar twill/ξ-noga=7 lifter to a conventional J or TL type bobbin frame.

The winding section 2 is equipped with a device for winding defect-free cheese packages. The device includes a thread cutter 9, a thread monitor 1o and a thread binding device, generally designated 19. However, in this drawing, a detailed illustration of the thread binding device 19 is omitted for the sake of clarity. Additionally, in the present invention, a control device 43 is provided, and the control device is connected to the drive device 13 of the twill/ξ thread 14, the yarn monitor 0, the yarn cutter 9, and the yarn binding device 19 by means of control wires. It is connected.

As can be seen in FIG. 1, the thread cutter 9 has a fixed force 7 and a movable blade 8. The thread 3 or yarn (15) runs backwards between the open rows of the thread cutter 9 and enters the measuring slit of the thread monitor 1°. A solenoid 44 is provided as an actuator of the movable blade 8, which is connected by a conductor 45 to a voltage source ↓6 independent of the control circuitry. The solenoid 44 is constantly energized and the movable blade 8
is being pulled towards the right hand. In order to shift the movable blade 8 along the fixed blade 7 towards the left to cut the thread 3, the force of the solenoid 44 is overcome by the force of the electromagnetic drive 22. The electromagnetic drive 22 is disconnected during the winding operation and is operatively connected to a control line 4.
It has 2.

The yarn monitor 10 is capable of running the yarn 3 and sending out a defect signal when a defective portion occurs in the yarn 3. The thread monitor is operatively connected to a control device 43 via a control line 41.

An electromagnetic drive 20 is provided for actuating the thread binding device 19. It is also possible to provide a drive motor instead of the electromagnetic drive.

06) The electromagnetic drive device 20 connects to the control device 43 via the control conductor 40.
is connected to the action.

The drive device 13 of the twill package 14 includes a motor 25.
The shaft 24 of the motor belongs to the contact 2 of the switching relay 27.
6 is connected to the motor rotation system. A frequency-controlled working voltage is supplied to the motor 25 via a conductor 28 .

In order to reverse the motor in order to unwind the cheese package, a working voltage of opposite polarity is supplied to the motor 25 via a line 29', a contact 29 of a further switching relay 27' and a line 28'. The switching relay 27' is connected to the control device 43 by a working connection line or control line 37. The already mentioned switching relay 27 is also connected to the control device 43 by a working connection line and a 4D control line 38.

The following devices are provided for rapid braking of the cheese package drive parts and the cheese package itself.

The first rapid control device 51 acts on the shaft 24 of the winding drum 12 and is actuated by an electromagnetic drive 23, which has an active connection line 39 leading to the control device 43. There is. A second rapid braking device 50 acts on the mounting mandrel 16 of the cheese-wound package 14 and is actuated by an electromagnetic drive 21 which connects a control line 35 to a control line 43 leading to a control device 43 .
have.

In order to avoid mutual influence of both rapid braking devices 50.51,
The already mentioned cheese-wound package lifter 18 is provided, of which the electromagnetic drive is connected to a control device 43 by means of an operational connection line and a control line 36.

The lifter makes it possible to move the cheese package away from the winding drum 12 during braking.

A special stop notification signal 53 can be received by the control device 6° 43 via a line 52.

The circuit diagram in Figure 3 shows the switching state of the switch during normal operation.

The relays 30, 31, time relay and switch button 49 are mounted on a control device 43.

The electromagnetic drives 18, 20, 21, 22, 23, the thread monitor 10 and the switching relays 27, 27' are arranged outside the control device 43 in FIG.

Switch button 49 is actuated to turn on relay 27 which switches motor 25 in the forward direction, which causes current to flow through the coil of relay 31 from positive to ground. Next, the holding contact 66 of the relay 31
, contacts 70, 71 and 72 occupy the switching state shown in FIG. After releasing the switch button 49, the ON state of the relay 31 is maintained via the closed contact 69 of the relay 30 and the closed holding contact 66.

As soon as the yarn monitor 10 sends out a yarn defect signal via the control conductor 41, the relay 30 turns off the contact 69, so that the relay 31 becomes de-energized. As a result, holding contact 66 and contact 70 are turned OFF, and contacts 71 and 72 are turned OFF.
Switch to N. Relay 31 then remains OFF even when contact 69 closes again.

Since the coil of the switching relay 27 becomes de-energized by turning off the contact 70, the contact 26 (FIG. 1) remains OFF, thereby making the motor 25 de-energized. However, at the same time contact 71 switches on electromagnetic drives 18, 21 and 23. As a result, both rapid braking devices 50, 5
1,! : The twill package lifter 18 operates.

The closing operation of contact 72 starts a clock system within the time relay, and the clock system switches contact 73, switching contact 74, and Wyno ξ contact 67 after a preset time has elapsed. This time is set so that the switching occurs when the twill package 14 has just come to rest.

When switching the Wyno ξ contact 67, the coil of the relay 31 is energized for a short time, so the relay is switched ON again,
The holding contact 6 is then opened via the already closed contact 69.
By closing 6, the ON state is maintained again. The electromagnetic drives 18, 21 and 23 are turned off by the opening of the contact 71. Contact 70 also closes, but switching relay 27 does not turn ON. This is because the switching relay is energized by the switching contact 74 and switches from the switching contact 741d conductor 75 to the control conductor 37.

By this switching, the substitute switching relay 27' is turned on.
As can be seen from Figure 1, the switching relay has contact 2.
9 switches the motor 25 to the reverse direction.

Since the braking of the motor 25 has been released during this time, the motor 25 can start a reverse rotation operation. The twill package then immediately reverses rotation. This is because the separation of the cheese package 14 from the winding drum 12 is again eliminated by turning off the electromagnetic drive single cheese package lifter 18.

By switching the electromagnetic drive device 22 ON, the inhibiting force of the actuator 19 solenoid 44 of the thread cutter 9 is overcome, so that the movable blade 8 can slide along the fixed blade 7, thereby cutting the thread. 3 is cut off. At the same time, the electromagnetic drive device 20
actuates the thread binding device, generally designated 19.

This operation also includes the operation of returning the upper thread produced by the thread cutting from the twill/groove cage 14. By this operation, defective portions of the yarn wound in the twill or O-cage are pulled back and removed.

The above-mentioned operation also includes an operation of receiving the bobbin thread generated by the thread cutting at approximately the position 1σ. The upper thread and the lower thread are joined, for example, by splicing or knotting using the thread joining device w19. All these operations are performed during a fixed time set in the time relay t, and after this time has elapsed, the contact 73, the switching contact 74, and the contact 67 switch as shown in FIG. Reoccupy the state. By switching the switching contact 74 to the conductor 75, the switching relay 27' is turned off, and the housing switching relay 27 is turned on.

The electromagnetic drive device 20 has a cutoff time delay means and a switching relay 2.
Advantageously, 7 has connection delay means. In this way, the yarn binding device 19 can perform the original suzo lining operation or knot forming operation when the motor 25 is stopped or when the twill package 14 is at rest,
Moreover, there is an advantage that the forward rotation direction starting of the motor 25 does not overlap with the above-mentioned thread joining operation.

Although the circuit diagram illustrated in Figure 1 is particularly simple, the present invention is not limited to this example.

Furthermore, it is possible to implement the above-mentioned or similar circuit configuration even more advantageously by incorporating a switching circuit.

In the embodiment shown in FIGS. 2 and 3, the winding section 2' is
It has a casing 84 containing a drive device, which supports elements visible from the outside, which will be explained in more detail below.

In this example, the cheese package l 4' is driven by a winding drum 105, the axis of rotation of which is designated by the reference numeral 144, with an inverted snow-circular groove. The thread 3' that is paid out from the payout bobbin (not shown) is
It first runs through the thread tensioner 95 defined in the casing 84 by the retaining foot 107. The yarn δ' then passes through the opened yarn cutter 9 and the yarn monitor 10, runs through the yarn guide member 143', comes into contact with the rough-in application roller 98, and passes through another yarn guide l-'' The thread 3' passes through the member 143 and abuts a vibration damping surface 150, which damps the thread vibrations towards the traversing motion triangle.The thread 3' then passes through the reverse spiral ξ spiral groove of the winding drum 105 and backwards. From there, it reaches the circumferential surface of the twill/ξtsu gauge 14'.

The cheese package 14' is supported by a fork-shaped bobbin frame 103. The bobbin frame 103 is rotatably connected to the casing 84 by a joint 54.

Both side arms of the bobbin frame 103 have bearings for rotatable tube receptacles of the package tube 55 of the cheese 14'. However, in FIG. 3, only the support 56 for the left winding tube receiver 57, which is connected to the left noride arm of the bobbin frame 103, is shown.

Between the package winding tube 55 and the support portion 56, meshing teeth are provided to prevent the package winding tube 55 from slipping along the winding tube receiving tray 57. The meshing teeth are separated from a radial web 58 mounted on the winding tube receiver 57, and the web fits into a notch 59 provided at the left end of the pan cage winding tube 55.

FIG. 2 shows details of a device unit, generally designated 19', for removing yarn defects and for 74J yarn splicing.

The yarn defect site removal and yarn recombination device unit 19' consists of the following parts.

A yarn tensioner 104 is arranged between the yarn tensioner 95 and the yarn cutter [1-1 9] on the side of the yarn travel path. The yarn stirrer 104 cooperates with a lower swirl nozzle 96 and an upper swirl nozzle 9f.

The lower swivel nozzle 96 is provided at the free end of the swivel arm 11, 15, and the swivel joint 22 of the swivel arm
4 is coupled to the casing 84. The upper pivot nozzle 97 is provided at the free end of the pivot arm 114 and the pivot joint 224' of the pivot arm is also connected to the casing 84. Both swivel arms 113.114
is hollow and filled with air.

Inside the swing arm 114, there is a swing joint 224'.
A thread sensor 60 is provided near the thread sensor 60 .

The broken casing 84 holds another casing 241 with a capture nozzle support 243. A capture nozzle support 243 is pivotably supported on the casing 241 and supports the yarn capture nozzle 134. The opening of the yarn catching nozzle 134 faces the yarn traveling path of the yarn 3' with a small distance therebetween. A suction pipe 136 is connected to the capture nostle support 24δ, and the suction pipe contains a controllable thread residue cutter 61.

FIG. 2 shows the winding station 2' during normal winding operation. The upper pivot nozzle 97 is in the dash-dot position 97', but is not loaded with articulating suction air. The yarn capture nozzle 134 is continuously loaded with suction air and is in a state ready to suck and capture the yarn in case the yarn loses yarn tension for any reason, even if the yarn is out of alignment.

The yarn monitor 10 constantly monitors the running yarn for any defective parts. As soon as a defective region occurs, the control device 43 specifically initiates the following actions:

First of all, the operations described in the description of FIG. 1 are carried out, with the yarn 5' not changing its running path even once. As soon as the twill package 14' comes to rest, the time relay t switches its contacts 73, switching contacts 74 and fee 8 contacts 67, as described in FIG. 1, and at this point the yarn 3' comes to rest. The thread cutter 9 is activated, and at the same time the electromagnetic drive device 2
0 (FIGS. 1 and 4), the operations of removing the yarn defect site and ladling the yarn are performed in the following order.

The switching direct 74 turns on the switching relay 27' (FIG. 1), and as a result, the motor 25 is reversed. Simultaneously with this reversal, the upper pivoting nozzle 97 is pivoted upwards and is loaded with suction air by opening a slide (not shown in FIG. 2).

Since the thread is divided into a bobbin thread and a needle thread, the needle thread loses its thread tension due to the reversal of the winding package 14'. At this time, the needle thread enters the thread catching nozzle 13 and is also sucked into the upper rotating nozzle 97 at the upper level. The pivoting nozzle 97 thus draws the thread out of the cheese package l4' in the form of a thread loop.

At the same time, the lower pivot nozzle 96 is pivoted to position 96'.

In this position 96', the lower pivot nozzle is also below the thread tensioner 95 and immediately to the side of the bobbin thread, as shown in FIG.

The suction of the upper thread from the twill package 14' is continued until the yarn defective portion reaching the circumferential surface of the twill package is sucked into the rotating arm 114 at approximately the height of the thread sensor 60. . According to FIG. 4, this duration is determined by the time relay t. The time relay t may be connected to the thread sensor 60 for switching its contact point C. If configured in this way, the time for switching the contact point of the time relay t is shortened, and the thread sensor 60 60 will be recognized at the time the presence of the thread confirms the unbowing of the thread defect site.

To ladle the thread, the lower pivot nozzle 96 is now pivoted back from the silver layer position 96', during which it received the bobbin thread, to the position shown in solid lines in FIG.

At the same time, the upper pivot nozzle 9f pivots to the chain line position 97' together with the received upper thread and the suctioned thread defective part. The suction action of the yarn catching nozzle 134 is caused by the upper turning nozzle 9.
Since the suction action in step 7 is also set weak, the upper thread is under tension. The needle thread comes into contact with the vibration damping surface 150, is automatically passed through the thread guide member 143, automatically comes into contact with the rough-in application roller 98, is automatically passed into the thread guide member 143', and the thread is automatically passed through the thread guide member 143'. into the measuring slit of the monitor 10 and against the thread cutter 9. At this time of contact, the winding drum 105 is still rotating in the reverse direction.

In contrast, the switching relay 27' has connection time delay means. Since such time delay means belong to the state of the art in electrical equipment, a detailed explanation thereof is omitted here. Both the connection delay and the disconnection delay can be achieved, for example, by means of separate connectable time relays, and the delay times of the time relays can be precisely determined and set in advance.

From the point in time when the time relay t shown in FIG. 1 is switched back on, the switching relay 27 is switched ON at 1, and the next operation continues.

The upper turning nozzle 97 moves to the chain line position 9 with the received needle thread.
At the same time as the lower turning nozzle 96 turns back to the starting position with the received bobbin thread, the upper thread and the bobbin thread are automatically inserted into the yarn splicer 104. As soon as the twill package 14' comes to rest again by turning off the housing switching relay 27', a splicing operation is performed between the bobbin thread and the needle thread in the conventional manner in the yarn splicer 104. After the operation is completed, the yarn fryer 104 releases the yarn.

When the lower swiveling nozzle 96 swivels upward, the bobbin thread has already been fed into the thread tensioner 95 and the electromagnetic drive device 2
As a result of the re-cutting in step 2, the upper thread automatically reaches between the two blades of the thread cutter 9 which are now wide open.

Immediately thereafter, the switching relay 27 is automatically switched ON. In the event that the yarn tension decreases when the yarn is released by the yarn splicer 104, the yarn 3' is kept under tension by the yarn catch nozzle 134 before the breakage of the switching relay.

The present invention is not limited to the illustrated embodiment.

The air can be fed in a conventional centralized manner in an automatic winder.

The yarn remaining cutter 61 shown in FIG.
Upper thread old man 1. was attracted by 4. It can be adjusted continuously to prevent the section from becoming too long. The thread cutter and thread catching nozzle 134 first receive the upper thread;
Then, for the first time, the upper swirling nozzle 97 starts to move the twill package 1
4' to pick up the upper thread, turn upward to the position shown in FIG. 2. During this suction operation, the upper swing nozzle 97 pulls out the thread part that has already entered the thread catching nozzle 134 from the thread catching nozzle 134.

The housing pivot arm 113 may be equipped with a thread cutter to ensure that the hooked bobbin thread end does not become too long.

In a different embodiment of the housing suction nozzle and the entire device for joining yarns, it is also possible to cut off the yarn only if a yarn defect site is detected. In this case, only the short thread section with the defect site needs to be excised. For this reason, when unwinding from the twill package,
The loosened yarn is sucked into the yarn capture nozzle 134 without actuating the yarn residue cutter 61.

Furthermore, it is also possible to use the yarn monitor 1o to confirm at what point the yarn defective portion was unwound. If necessary, a separate circuit arrangement is provided for angularly coupling the thread monitor 1°.

All these operations are then frustrated in the shortest possible time.
