Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention consists of a plurality of winders in which multiple spindle winding units are arranged side by side to form one machine, and the winding units can be used for a set number of times. The present invention relates to an automatic winder configured to stop the weight and indicate that yarn splicing is impossible when yarn splicing errors are repeated, and particularly to an abnormality alarm device for the automatic winder.

[Conventional technology] A winding unit with multiple spindles is installed in parallel.
In an automatic winder consisting of two machine bases,
When each winding unit detects a defective part such as a slub in the running yarn, it forcibly cuts the yarn and splices the upper thread on the package cage side and the lower thread on the yarn supply bobbin side, thereby eliminating the yarn defect. It is designed to remove parts. Also, tension breaks other than slabs,
Even when there is no yarn on the yarn supplying bobbin, the same yarn splicing operation as described above is performed by detecting that the yarn is not running.

If the yarn splicing is successful in the above yarn splicing operation, normal winding will start again. If the yarn splicing is not successful even after the set number of yarn splicing operations, it will be determined that the unit is unable to splice the yarn, and the unit will By protruding a yellow button, the machine displays an indication that yarn splicing is not possible, stops winding, and waits for the operator's action.
This is because there is a high probability that the yarn splicing will not be successful even if the yarn splicing is attempted any further, so the operator goes around to the unit where the yellow button in question is protruding.
I will have to make some adjustments.

[Problem to be Solved by the Invention] However, since a large number of each winding unit are installed in parallel, the operator has to constantly go around to see if the yellow button, which is the means for indicating that thread splicing is not possible, is in the protruding state. If the winder unit cannot be identified and patrols are neglected, the operating rate of the winder unit that has stopped winding will decrease. Furthermore, if there are many indications that yarn splicing is not possible, there is a possibility that a common cause of the abnormality exists, and prompt action by the operator is required.

The present invention aims to solve the above problem.

[Means for Solving the Problems] The present invention consists of a plurality of winders in which multiple spindle winding units are arranged in parallel to form one machine, and the winding unit repeats yarn splicing mistakes a set number of times. In an automatic winder that is configured to stop the weight and indicate that yarn splicing is not possible when the spindle is stopped, the winding length of the yarn to the package cage of each weight that makes up the machine is displayed on one side of each machine stand, as well as the yarn splicing error mentioned above. A fixed length device is installed to grasp and store the number of windings of the winding unit, and a warning light is installed on the top of the device so as to be higher than the winding unit. A statistical counter that adds up the number of weights each time a weight that is in an unrepeatable display state occurs, and when the integrated value of the counter reaches an arbitrarily set predetermined number of weights m (m≧2). means for outputting an alarm signal to turn on the above-mentioned warning light; and means for clearing the above-mentioned statistical counter and turning on the warning light when all the weights displaying a thread splicing impossible indication in the machine machine on which the above-mentioned warning light is lit start winding operation. This configuration includes a means for turning off the light.

[Function] Each time a spindle that is displayed as being unable to splice occurs in the winder machine to which it belongs, each fixed length device adds up the number of spindles using a statistical counter. Then, this integrated value is a predetermined number of weights m (m≧2)
If this happens, it is determined that the number of winding units in the yarn splicing disabled display state due to protrusion of the yellow button, etc. has exceeded the permissible limit, and an alarm signal is output and a warning light is turned on.

This warning light is installed on the top of the fixed length device located on one side of each machine so that it is higher than the winding unit, so the operator can
Even if you are on the side of the machine that is far away from the machine, you can visually recognize the lighting of this warning light. The operator goes to the machine stand where the warning light has been lit, finds a weight in the machine stand that is indicating that thread splicing is not possible, and repairs the weight.

The above integrated value is set in the range of m≧2 and the case where m=1 is excluded is when there is only one winding unit (m=1) in one machine that is displaying the yarn splicing impossible state. This is also because there is no urgent need for modification by the operator. That is, the event in which the warning light is turned on indicates the urgency of the need for rework by the operator. For example, if the set number of spindles m is m = 3, the above warning light will turn on when there are 3 spindles in one machine that are in a state where thread splicing is not possible.
The state in which this lighting occurs, that is, the state in which 3 or more spindles are indicating that thread splicing is not possible, is a more urgent state than the case where only 2 spindles or 1 spindle is displaying that thread splicing is not possible. It may also be indicative of a highly urgent condition, as in the case of the first three spindles in a group of stop spindles occurring in clusters.

The operator monitors the presence or absence of the warning light, and when the warning light comes on, he goes to the machine, but from this alone, the operator naturally distinguishes whether there is an emergency or not, and the thread splicing impossible display state is 1
You are freed from the need to frequently go to a machine that only has weights.
Therefore, even if the operator does not perform frequent patrol monitoring as in the past, the operating rate does not decrease significantly.

The operator who came to the machine with the warning light on found the weight in the machine that indicated that thread splicing was not possible, removed the cause of the defect by making repairs, etc., and then removed the wine by pressing the protruding yellow button, etc. Return the winding unit to the winding operation state. When this work is completed for the winding unit with the number of spindles mentioned above that was in the yarn splicing impossible display state, and all the weights that were in the yarn splicing impossible display state start the winding operation, the fixed length device of the machine concerned will adjust the above statistics. Clear the counter and turn off the warning light. Therefore, while the warning light is on, the operator can judge that there is still a winding unit in the machine that needs to be repaired, and when the warning light goes off, the thread splicing is no longer possible. It can be determined that all the weights in the display state have entered the winding operation. Therefore, even if a large number of weights on the same winder machine are displayed as being unable to splice, it is possible to remove the cause of the defect by reworking all of the weights, and remove untreated weights that do not undergo rework. It is possible to eliminate the waste of the operator who leaves the machine while leaving the machine behind and returns to the same machine a short time later when the warning light turns on.

[Examples] Examples of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 indicates one of a plurality of winders constituting an automatic winder. One machine is constructed by arranging multiple winding units 2 in parallel, and each winding unit 2 is provided with a yellow button 3 for indicating that yarn splicing is impossible, which projects when the yarn splicing mistake is repeated a predetermined number of times. Reference numeral 4 denotes a fixed length device that can grasp and memorize the winding length of the yarn to the package P of each weight constituting the machine and the number of times of rewinding due to the yarn splicing error, and is installed on one side of each machine. A warning light 5 is erected at the top of each fixed length device 4 so as to be higher than the winding unit 2.

FIG. 4 shows an example of a winding unit, in which the yarn is wound from the yarn supply bobbin B to the package P. Appropriate tension is applied by a tensor 10 through a guide 9, and then through a slab catcher 11.
It is wound around a package P which is rotated by a traversing drum 1.

At this time, remove defects in the yarn using the slab catcher 1.
1 is detected, the cutter built in the slab catcher 11 operates to forcibly cut the running yarn and winding is stopped, while the suction mouth 13 operates to cut the running yarn on the package P side. The yarn is guided to the yarn splicing device 14, and the relay pipe 15 guides the lower thread on the bobbin B side to the yarn splicing device 14, and the yarn is spliced by the yarn splicing device 14. If the splicing is successful, winding starts again. be done. A large number of such winding units 4 are arranged in parallel in the direction perpendicular to the paper surface of FIG.
The machine consists of two winder machines.

In FIG. 2, the yellow button 3 is attached to the receiving material 17 on the frame 16 on the operator's side of the wine dinning unit.
It is slidably supported by. The shaft 18 of the yellow button 3 is connected to a lever 20 that can swing around a single shaft 19, and the pin 21 at the other end of the lever 20 is connected to the output shaft of a rotary solenoid as a solenoid SO for indicating that thread splicing is not possible. It is located within the long groove of the fixed lever 22. Fig. 2 shows a normal winding state, that is, a state in which the yellow button 3 is pushed in, and the actuator 23 of the micro switch (MS1) is pushed by the lever 20, and winding is performed with the switch MS1 in the ON state. be exposed.

24 is a yarn splicing control device for the winding unit 4, and 25 is a setting device for the number of repetitions of the yarn splicing operation. The control device 24 operates once during one cycle of yarn splicing operation.
It counts the trigger signal from the micro switch that is turned on twice and detects yarn splicing errors. When the yarn splicing operation is repeated by the set value (n times) determined by the setting device 25, a button actuation signal is output from the control device 24, and the rotary solenoid SO is turned on. As a result, the lever 22 turns clockwise at a certain angle, the yellow button shaft 18 is pushed to the left, and the yellow button 3
stands out. At the same time, the micro switch MS1
The unit becomes OFF, and the yarn splicing and winding operations are subsequently stopped and the unit becomes a stop table.

Therefore, if the set value (n) is set to 3, the counter (CNT) will count up when thread splicing errors are made three times, and the contact (CNTa) in the circuit to the thread splicing failure display solenoid (SO) will be counted up. is closed, the solenoid (SO) is energized, and the yellow button 3 for indicating that thread splicing is not possible as shown in FIG. 4 protrudes. In addition, the setting value n is
If it is difficult to pull out the thread end with fine thread count, n = 4.
Alternatively, set n=5, or set n=2 or n=1 when the yarn is thick and easy to splice.

The pulses indicating the number of yarn splicing errors in each of the winding units are inputted to the winder's length fixing device 4 together with the pulses indicating the winding yarn length of the package. The length fixing device 4 recognizes which weight's winding unit has a yellow button based on the number of thread splicing errors, and determines the number of weights whose yellow button is displayed as m (m).
≧2) When the weight is exceeded, an alarm signal is output, the warning light 5 on the machine is lit, and the operator is notified.

FIG. 3 shows the alarm control flow of this fixed length device 4.

The CPU built in the fixed length device 4 receives the pulses sent from each winding unit 2 and identifies whether or not the pulses are continuous repeating pulses (step ~). If the pulses are continuous, the winding is continuing, so these pulses are counted and added up as the number of windings (step). If it is a single pulse, it is determined that it is caused by a thread splicing error, the yellow counter is incremented by 1, and the yellow counter is waited for to count up to a predetermined value n (here, n=3) (step ~) . yellow counter is n=3
When the count is up, the yellow button 3 will stick out,
The winding unit 2 enters the above-mentioned yarn splicing impossible display state. In this way, when the winding unit 2 enters the yarn splicing disabled display state, the statistical counter common to each winding unit 2 is incremented by 1 (step). Therefore, each time a winding unit 2 in which yarn splicing is not possible occurs in the winder 1,
The contents are updated and the number of weights is accumulated.

In order to know the number of units in the yarn splicing impossible display state that occurred during the winder, the CPU inputs the contents of the above statistical counter at predetermined time intervals, and checks whether the contents have reached the predetermined number of spindles m, which is the permissible limit. Look (step ~). When a winding unit with a predetermined number of spindles (m), for example three spindles, becomes in a yarn splicing impossible display state, the warning light 5 is turned on to notify the operator of this fact (step).

When the warning light 5 is turned on, the operator goes around the winder 1, removes the cause of the winding failure in the three-spindle winding unit 2 which is unable to splice yarn, and starts the winding unit 2. When one spindle of the winding unit enters the winding operation, the yellow counter belonging to that unit is cleared, and when all three spindles enter the winding operation, the contents of the statistical counter are cleared and the warning light 5 is activated. The display will turn off. Therefore, while the warning light is on, the operator can determine that there is still a winding unit in the machine that needs to be repaired.

The protruding state of the yellow button 3 is a natural result of a thread splicing error and is not artificially caused to protrude. Therefore, the warning light 5 is turned on to indicate that the yellow button 3 is not able to be spliced. This eliminates frequent patrol monitoring by operators in relatively non-urgent situations, such as when there is only one spindle in one winder, and in cases of emergency where the cause of an abnormality is in a common location within the winder. You can remove this as soon as possible.

[Effects of the Invention] As described above, according to the present invention, the warning light is installed at the top of the fixed length device located on one side of each machine so as to be higher than the winding unit. Even if you are on the side of the machine that is far away from the machine concerned, you can visually recognize the lighting of this warning light. This warning light lights up when there is an emergency situation in which a predetermined number m (m≧2) or more of weights that are in a yarn splicing impossible display state occur in the winder machine to which each fixed length device belongs. If there is no emergency, such as when there is only one spindle (m = 1) in the untransferable display state, the light will not light, so the operator should monitor whether the warning light is on or not, and if the warning light is on, the only thing to do is to go to that machine. As a result, the operator can naturally distinguish whether there is an emergency or not, and is freed from the need to frequently visit a machine where only one spindle is displayed as being unable to splice. Therefore, even if the operator does not perform frequent patrol monitoring, the operating rate will not be significantly reduced.

Further, the length fixing device is configured to clear the above-mentioned statistical counter of the machine and turn off the warning light when all the spindles in the machine in which the thread cannot be spliced start the winding operation. Therefore, when an operator goes to a machine with a warning light on, finds a spindle in the machine with a display indicating that thread splicing is not possible, and removes the cause of the winding failure by repairing it, etc., the predetermined number of spindles m
If the warning light is still on after removing the cause of the defect, the operator must determine that there is still a winding unit in the machine that should be repaired or otherwise removed. Therefore, it is possible to remove the cause of the defect for all the spindles that are in the yarn splicing impossible display state that caused the warning light to turn on. Therefore, even if a large number of weights on the same machine are displayed as unable to join, the warning light will turn on after a short time if the machine leaves the machine with unprocessed weights left behind. This eliminates the need for the operator to return to the same machine again.
