Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a yarn splicing control device in an automatic winder, and more particularly to a control mechanism for a yarn splicing failure indicating means for indicating failure of yarn splicing.

[Prior Art] Among automatic winders in which a large number of winding units are arranged in parallel, there are those in which each unit is provided with an automatic yarn splicing device, and those that have a yarn splicing cart that moves between a plurality of units.

In a winder equipped with such an automatic yarn splicing device, the yarn is forcibly cut in order to remove a defective part of the yarn being wound, or if the spinning bobbin on the yarn feeding side runs out of yarn. Thread breakage may also occur due to other reasons. In any of the above cases, the winding operation stops, that is, the drum for driving the winding package stops. Upon this stop, the yarn splicing operation is immediately started in the winder having a yarn splicing device in each unit, and the yarn splicing device performs yarn splicing on the yarn end on the winding side and the yarn end on the yarn feeding side. In addition, in a winder having a yarn splicing cart that moves along multiple units, a yarn splicing command signal is issued mechanically or electrically from the unit where yarn breakage has occurred, and the yarn splicing cart that is running The winding unit stops at the commanded position and splices the yarn.

In any of the above types of winders, if a yarn splicing operation is performed in a certain winding unit and the yarn splicing is successful, the winding operation will be restarted, but if the yarn splicing fails and the yarn splicing operation is completed the set number of times. If the yarn splicing is not successful even after twisting, the yarn splicing failure display means of the winding unit indicates that the yarn splicing is not possible. When the operator discovers a winding unit that has stopped due to yarn splicing failure due to the above display, he/she should perform processing operations to eliminate the cause of yarn splicing failure and resolve the yarn splicing failure display. If so, the yarn splicing operation is automatically restarted.

As mentioned above, conventionally, the yarn splicing-incapable unit has been designed so that its winding operation can be resumed only after the operator has made some adjustments. Therefore, after the display indicating that yarn splicing is not possible, the winding operation is stopped until the operator discovers the unit in question. However, depending on the cause of the yarn splicing failure described above, for example, the yarn feeding side hobbin is not supplied during the set number of yarn splicing operations, making the yarn splicing impossible, but after the yarn splicing failure is displayed, the bobbin If the yarn splicing operation is further performed when the yarn splicing is supplied, the splicing may be successful.

In this way, even after a set number of yarn splices have failed, stopping even the winding unit, which has a possibility of succeeding in yarn splicing if it performs further yarn splicing operations, reduces the operating efficiency of the unit. cause it to happen.

[Problems to be Solved by the Invention] In the conventional method, winding is not restarted unless the operator releases the yarn splicing impossible display means for a winding unit that is stopped because yarn splicing is impossible. However, this arrangement was extremely inefficient in an automatic winder in which a large number of winding units were arranged side by side.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks of the prior art by automatically releasing a thread splicing impossible display means using a work cart, thereby improving the operating efficiency of a yarn splicing control device for an automatic winder. Our goal is to provide the following.

[Means for Solving the Problems] As shown in FIG. 1, the automatic winder yarn splicing control device of the present invention is such that a large number of winding units 2 arranged in parallel to constitute an automatic winder 1 are connected to a yarn splicing device. It is provided with a thread splicing impossible display means 12 which stops the machine when it fails and displays that the thread splicing is impossible, and when the display is canceled, causes the automatic splicing to be performed thereafter. Further, a work cart 3 is provided which travels along a large number of winding units 2 arranged in parallel.

This work cart 3 includes a display detection sensor 15 that detects the display of the thread splicing impossible display means 12, and addresses assigned to each winding unit 2...AD _o-1 , ADn,
an address sensor 100 that detects AD _o+1 . A control means 110 is provided.

This control means 110 stores the number of times yarn splicing is not possible for each winding unit 2 based on the detection outputs of the display detection sensor 15 and address sensor 100, and when the number of times the yarn splicing is disabled is displayed for the first time, the yarn splicing is performed while traveling on the work cart 3. A yarn splicing command is issued to the command means 16 to display the relevant display, and the display of the yarn splicing impossible display means 12 of the winding unit 2 which is stopped due to the yarn splicing being impossible is canceled, and when the number of times the display is the second time or more, the said display is The carriage 3 is stopped at the position of the winding unit 2, which is stopped due to the yarn splicing being impossible.
A yarn splicing command is issued to the yarn splicing command means 16 to cancel the yarn splicing impossible display means 12 of the winding unit 2, and a yarn withdrawal command is issued to the beater means 32 to cause the yarn to be withdrawn from the package 9.

[Operation] When the display detection sensor 15 detects a winding unit 2 that is stopped with the display of the thread splicing impossible display means 12 displayed, the number of display times for that winding unit 2 is determined based on the address sensor 100. The control means 110 determines whether or not.

If the display number is the first time, the work cart 3 does not stop, so when passing the unit 2 concerned, the yarn splicing command means 16 on the cart 3 side runs along the display of the yarn splicing impossible display means 12 on the unit 2 side. The thread splicing operation is forcibly started. A yarn splicing error due to no bobbin being supplied to the yarn feeding side will definitely exist when the display is displayed for the first time, and a while after the yarn splicing error has occurred, a new bobbin will be supplied and the cause of the error will occur. will be lost, so please try another unit 2.
When the work cart 3 finds the winding unit 2 after performing the work, there is a possibility that the yarn splicing will be successful by simply canceling the display of the yarn splicing impossible display means 12 without doing anything. This is because it is expensive. In this case, since the display is only canceled, it is not enough to stop the cart 3.

If the number of times of display is the second or more, the work cart 3 stops at the position of the winding unit 2. Then, the yarn splicing command means 16 on the trolley 3 side cancels the display on the yarn splicing impossible display means 12 on the unit 2 side, and forcibly starts the yarn splicing operation. At this time, during the yarn splicing operation, the beater means 32 on the trolley 3 side forcibly pulls out the yarn from the package 9 on the unit 2 side. When the number of times the display is displayed is the second time or more, there is a high probability that the thread will be spliced incorrectly because the thread is not pulled out from the package cage 9 side. After doing so,
This is because there is a high possibility of success if the yarn is spliced. In this case, it is necessary to stop the carriage 3 in order to draw out the thread.

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

13) a Structure of an automatic winder (FIGS. 2 and 3) In FIGS. 2 and 3, an automatic winder 1 is constructed by arranging a large number of winding units 2 in parallel,
A work cart 3 is provided which runs along the winding unit 2. In the case of this embodiment, the above-mentioned work cart is a cart 3 with a built-in automatic doffing device.
applies.

As shown in the second figure, the winding unit 2 transfers the yarn 5 drawn out from the yarn feeding bobbin 4 through a tension device 6, a slab catcher 7, etc. to a winding package 9 rotated by a traversing drum 8 in a set amount. It winds the thread. Further, each unit is equipped with a yarn splicing device 10, and the yarn end on the bobbin 4 side and the yarn end on the package 9 side are spliced by known means.

Further, on the front surface of the winding unit 2, a yarn splicing failure display means 12 is provided, which is a yellow button 11 or the like that projects forward when yarn splicing fails despite a predetermined number of yarn splicing operations. Therefore, while the button 11 is in the protruding position, the winding unit stops winding, and by pressing the button 11, the yarn splicing operation is automatically restarted. Note that the other button 13 is a switch for driving the drum. That is,
The button 11 for indicating that thread splicing is not possible can be positioned in two positions, the protruding position and the pushed-in position.When the other button 13 is pressed, the switch is turned on, the drum starts rotating, and when the button is released, the spring force is applied. It is a switch button that causes the drum to return to its original protruding position but continue to rotate.

Further, the work cart 3 that runs along the unit is suspended from the ceiling rails 14, 14 via wheels, and travels back and forth or patrols along the winding unit. Although the above-mentioned cart 3 is an automatic doffing cart in this embodiment, it is a ground cart, for example, runs along a rail on the floor below the unit, and supplies spinning bobbins to the unit during the run. It may be a bobbin supply cart that moves along the bobbin, or a moving body that moves along with other units.

As shown in the second figure, the carriage 3 includes a display detection sensor 15 for detecting a yarn splicing impossible unit, and a yarn splicing sensor 15 that is activated by the detection sensor 15 to cancel the yarn splicing impossible display and forcibly execute the yarn splicing. Command means 1
6 is provided. In this embodiment, the detection means 16
As the yarn splicing command means 16, an arm 17 for pushing the button 11 is used.

Note that 70 is a green lamp provided on the side of the unit 2, which lights up when the tube is full.

b. Structure of Yarn Splicing Impossibility Display Means (FIG. 4) In FIG. 4, the Yarn Splicing Impossibility Display Means 12 is shown. 11 is at the two-dot chain line position 11a during normal winding.
This button is located in the pushed-in position and projects to the solid line position 11 when the thread splicing is not successful even after a predetermined number of thread splicing operations.If the button 11 in the protruding position is forcibly pushed in, the thread splicing will be performed again. The operation begins.

13 is a button switch for starting the drum.

In addition, the above-mentioned thread splicing impossible button (hereinafter referred to as yellow button) 11 has a light reflecting surface 18 on the outer periphery of the button that is yellow so that it can be detected by an optical sensor 15, which will be described later.

c. Configuration of yellow button automatic processing device (Figures 5 and 6)
7) The yellow button automatic processing device 30 provided on the work cart will be described with reference to FIGS. 5 and 6.
The processing device 30 includes two display detection sensors 15 and 57 for detecting a stopped winding unit, a yarn splicing command arm means 16 for forcibly starting yarn splicing by pressing a yellow button, and a yarn splicing command arm means 16 for forcibly starting yarn splicing by pressing a yellow button. Beater device 32 for ensuring withdrawal
and a drive mechanism 34 for each of the above-mentioned operating members.

The yarn splicing command arm 17 is pivotally supported by a fixed shaft 36 of a support frame 35 fixed to the work cart 3, and a pressing piece 37 for pushing the yellow button is attached to the lower end of the arm 17.

As shown in FIG. 7, the left and right end plates of this pressing piece 37 are gently curved toward the back surface so that the yellow button can be pressed in even while the vehicle is running.

On the other hand, of the levers 38 and 39 integral with the arm 17, the lever 38 is connected to a rod 41 driven by a solenoid 40, and the lower lever 39 supports a cam follower 43 that comes into contact with a cam plate 42.

Furthermore, the beater device 32 for making it easier to take out the yarn end of the package cage has a contact piece 53 with the yarn layer attached to an arm 52 that can rotate around a fixed shaft 56 and a cam follower 5 that comes into contact with a cam plate 54.
5. When the winder is reversed, the contact piece 53 comes into contact with the surface of the yarn layer and serves to separate the yarn end from the yarn layer and suck it into the suction mouth 51a, and is made of rubber, synthetic resin, metal, or the like. It has a width that spans almost the entire width of the busbar of the package.

In FIG. 6, reference numeral 15 denotes a reflective phototube sensor for detecting the yellow button when the truck is traveling to the right, and 57 is a phototube sensor for detecting the yellow button when the truck is traveling to the left.

Reference numeral 58 denotes a motor driven by the ON signal of the sensor 15 or 57, which drives the pulley 6 of the camshaft 59.
The camshaft 59 is connected to the camshaft 59 via the belt 61
Rotate.

Note that 62 is a sensor for detecting one revolution of the camshaft 59, which detects the iron piece 63 fixed to the pulley 60.

d Configuration of the control system of the work cart (FIGS. 8 and 9) The control system of the work cart will be explained with reference to FIGS. 8 and 9. Automatic winder 1 as shown in Figure 8.
A yellow button automatic processing device 30, which will be described later, is installed adjacent to a built-in automatic doffing device (hereinafter referred to as AD) 19 on a work cart 3 that travels along the winding unit 2. The automatic doffing by the AD 19 or the yellow button processing by the yellow button automatic processing device 30 is performed on the full pipe weight or the yellow button weight.
The main computer 81 installed in the main body control box 80 of the automatic winder 1 always recognizes which spindle is a full pipe weight or a yellow button weight, so the optical transmission device installed on the trolley 3 and the main body side A command is given to the AD 19 or the yellow button automatic processing device 30 via 82 and 83.

This will be explained in more detail using FIG. 9.

The unit's full ball and yellow button information is sent to the main computer 81 by wire. On the other hand, the automatic doffing and yellow button processing sequencer 90 provided on the trolley is connected to the main computer 8.
1 contains the weight NO information, and conversely the main computer 81
From there, running/stopping information calculated and determined as to which direction the cart should be moved to the left or right or where to stop it more efficiently is optically transmitted to the sequencer 90. The above-mentioned sequencer 90 receives full lamp and yellow button information from the green lamp detection sensor 91 and the yellow button display detection sensors 15 and 57, and the sequencer 90 also inputs the address sensor 1.
00, the address AS assigned in advance to each type is read and always sent to the main computer 81 as address information.

e Configuration of yellow button automatic processing sequencer (10th
Figure) In Figure 10, the yellow button automatic processing sequencer will be explained in particular. The circuits shown in the figure are provided on the AD side by the number of units.

When the yellow button display detection sensor detects the yellow button, the yellow button contact YBAa and the address contact ASa of the weight circuit where the yellow button was detected close.
Furthermore, keep relay KR is set only when timing contact TMa closes. Therefore, the number of the yellow buttons detected is stored in the keep relay KR.

On the other hand, if the yellow button display detection sensor does not detect the yellow button, the yellow button non-contact YBNa and
Address contact of weight circuit where yellow button is not detected
When ASa closes and timing contact TMa also closes, keep relay KR is reset. This keep relay KR is also reset when the yellow button processing contact YBSa closes in the yellow button push processing performed based on the yellow button detection. Therefore, past yellow button information will be kept on relay when yellow button processing is performed.
It will be deleted from KR.

Further, when the keep relay contact KRa, the timing contact TMa, and the address contact ASa are all closed, the motor stop relay RA for driving the work cart is energized. Therefore, the work trolley stops only when the keep relay KR has already been set, and remains in the running state when it is set for the first time.

f Address sensor configuration (Figures 11 and 12)
11 to 13, the address sensor will be explained. While the work cart 3 is traveling and doffing, it is necessary to know which spindle it is currently on. Therefore, the rail 14 on which the work cart 3 runs
The address AS of each weight is on the mounting side, that is, on the ceiling side.
, and this address AS is read by the address sensor 100 attached to the work cart 3 side.

The address on the ceiling side is given by an iron plate 122 with a hole 121 corresponding to the address AS. For example, if the number of weights is 1 to 60, the iron plate 122
Seven holes 121 with weights of 2 ⁰ to ^{2 6} can be made in the width direction. These holes 1
Reference numeral 21 is a long hole along the running direction of the truck 3 so that the address sensor 100 can always correctly detect the truck 3 no matter where it stops.

The address sensor 100 on the trolley side is a steel plate 12
It is composed of seven proximity switches 123 corresponding to the holes 121 provided in the work cart 3, and it is possible to know which spindle the work cart 3 is currently in depending on which proximity switch 123 is turned on or off.

FIG. 13 shows an example of the address assigned to the 10th spindle. Elongated holes 121 are formed at locations weighted 2 ¹ and 2 ³ .

In addition, in the above embodiment, as a means for knowing the address, an absolute address type was used in which a plurality of holes were provided corresponding to each type of address, but only one dog was provided on each weight to determine the origin position, and the origin was It is also possible to use a relative address system in which the address is determined based on how many dots are detected from the cone.

The operation of the device as described above will be explained in the following order.

g Operation when the yellow button is detected for the first time h Operation when the yellow button is detected for the second time g Operation when the yellow button is detected for the first time Normal winding is performed with the yellow button 11 depressed. After yarn breakage occurs, if the yarn splicing is not successful even after a predetermined number of yarn splicing operations, the yellow button 11 protrudes.

Next, while the trolley 3 is running, when the display detection sensor 15 or 57 on the trolley side detects the winding unit 2 which has stopped winding with the yellow button 1 protruding, the sequence circuit shown in FIG.
Although the keep relay KR of the unit 2 memorizes the first yellow button detection, the stop relay RA is not energized, so the truck 3 continues to move.

In this case, while the cart 3 is running, the yarn splicing command arm 17 is operated and the yellow button 11 is pressed.
Push in to force the thread splicing. A detailed explanation of the operation of the yarn splicing command arm 17 will be given to Section h below, and here, we will explain the first yellow button pressing operation by the yarn splicing command arm 17 schematically.
This will be explained using Figure 4.

Pressing piece 3 attached to the tip of the thread splicing command arm
7 approaches the winding unit 2 from the standby position before approaching the winding unit 2 where the yellow button 11 protrudes and winding is stopped, and presses the warped end plate of the pressing piece 37. Adjust the position to the height of the top of the protruding yellow button 11.

Then, the end plate of the pressing piece 37 hits the top of the yellow button 11 during the traveling process, and because of its warp, it smoothly pushes the yellow button 11 and passes without any impact. Note that since the warped end plates are located at both ends, the pushing operation can be performed without any problem even when traveling from either the left or the right. By pressing the yellow button 11 while the machine is running, only the suction mouse for pulling out the yarn end and the yarn splicing system are operated, and the movement of the beater system 32 is blocked by appropriate means. . Therefore, the winding unit 2 into which the yellow button 11 is pressed simply splices the yarn without scraping out the yarn. This is because, in the case of a yarn splicing failure, the bobbin is often not yet supplied to the yarn supplying side. This is because there is a high probability that a new bobbin has been supplied, and if the yarn splicing is forced again by the action of the yarn splicing command arm, the probability of successful yarn splicing increases.

In this way, the first time you press the yellow button while driving, even if you use a trolley with built-in AD.
It does not reduce AD ability, and by pressing the yellow button, it is possible to lead a percentage of them to successful thread splicing.

h Operation when the yellow button detection circuit operates for the second time In Fig. 5, when the display detection sensor 15 or 57 on the trolley side detects the winding unit 2 which has stopped winding due to the yellow button 11 protruding for the second time. In the sequence circuit shown in FIG. 10, the keep relay KR of the unit is already in the set state by the first yellow button detection, so the stop relay RA is energized. As a result, the traveling motor on the upper part of the truck 3 immediately decelerates, and the recess 66 of the positioning plate 64 shown in FIG. When a limit switch (not shown) detects this, the solenoid 40 shown in FIG. 5 is turned on.

When the solenoid 40 is turned on, the rod 41
is pulled up, the yarn splicing command arm 17 turns counterclockwise from the standby position, and the pressing piece 37 pushes the protruding yellow button 11. Along with this pushing, the drive mechanism of the yarn splicing device inside the unit is turned on, and the yarn splicing operation is started. That is, when the suction mouse for pulling out the yarn end on the side of the package cage 9 turns clockwise from the standby position 51c to the working position 51a, the drive motor 58 of the yellow button processing device shown in FIG. 6 is turned on.

That is, the camshaft 5 is driven by the motor 58.
9 rotates, and the beater device 32 and yarn splicing command arm 17 act in a timely manner by the respective cam plates 42, 54 and cam followers 43, 55. First, the yarn layer contacting piece 53 of the beater device moves toward the package cage, and as shown in FIG. 5, when the package is reversed, it contacts the yarn layer and makes it easier to take out the yarn end.
The yarn end is sucked into the suction mouth 51a, and the suction mouth 51a rotates in the opposite direction so that the yarn takes a predetermined yarn path Y1 between the package 9 and the yarn splicing device as shown in FIG.

If the yarn splicing is successful, the yarn splicing command arm 17 returns and the winding continues with the yellow button 11 pressed in.

On the other hand, if the yarn splicing fails, the yarn splicing command arm 1
7 returns and the yellow button 11 protrudes again even after the thread splicing operation is completed.

At this time, there is some cause on the package cage side that causes the yarn splicing to fail, and the operator needs to make some adjustments.Therefore, even if the cart arrives in this state, the yellow button 11e is not detected. Detection thereof shall be prevented by appropriate means. As a result, the truck passes. When an operator finds a unit with a protruding button 11, the operator repairs the package side and presses in the yellow button 11 to return it to the original state 11a.

As described above, according to this embodiment, the yellow button detection is set to 1 in order not to degrade the AD capability of the work trolley.
For the second time, press the yellow button while driving. This alone will result in some success in splicing.

Next time when you come to the same take-up unit again, if the yellow button is not out, reset the sequence keep relay. However, if a yellow button has come out, the winding unit stops at that winding unit, and the automatic yellow button processing device is activated to scrape out the yarn end of the package and then process the yellow button.

In this way, for a unit that is stopped due to being unable to splice yarn, the yellow button is initially pressed while the unit is running, and then the yellow button is automatically pressed again after the unit has stopped and the obstacle has been removed. So, unless a worker comes and presses the yellow button,
Compared to cases where winding never resumes and always stops when the yellow button protrudes,
Becomes extremely efficient.

[Effects of the Invention] According to the present invention, although the winding unit is stopped because the yarn cannot be spliced, in the next yarn splicing operation, the yarn splicing command is simply issued to the unit that has a possibility of succeeding in yarn splicing. If the winding is restarted at the time, the trolley is automatically processed while the trolley is running, and if the winding cannot be resumed unless the thread is pulled out from the package cage, the trolley is stopped and the thread is automatically processed. As a result, the winding can be restarted without waiting for the operator's processing, and the operating efficiency of the winder can be further improved compared to the case where the cart is stopped all at once.
