Abstract

PURPOSE:To prevent any yarn count mixing from occurring by stopping operation of a circulating distribution passage for at least the said winding section when judging a fact that a color of a bobbin being detected by a color sensor differs from that of a yarn type to be handled. CONSTITUTION:When pirn yarn 17 circulating in a circulating distribution passage comes to a position of a yarn count mixing detector, an optical path of the position sensor 8 is shaded by a bobbin 30, and at this time a bobbin color sensor 9 reads a color of this bobbin 30, and whether the color is that of a kind of a tray 18 being read by a tray sensor 6, namely, a color to belong to the winding section or not is discriminated by a yarn count mixing detector circuit. When yarn count mixing is detected, a supply of the new pirn yarn 17 out of a pick finding device is stopped, while a series of conveying systems inclusive of a conveyor line, a pirn yarn feed passage and the circulating distribution passage are stopped. Thus, such a possibility that another type of yarn might be mixed in a package and rolled in it can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a No. 5 prevention device in a yarn conveying system to a winder.

[Prior Art] A tube yarn that has been wound up by a spinning machine is generally rewound into a package of a size and shape suitable for removing yarn defects or for post-processing. The automatic winder used for this rewinding process consists of multiple winding units arranged side by side to form one winder, and the yarn that is fed to each unit and pulled out at high speed is rotated by a drive drum. When one thread of the pipe thread is used up, the next pipe thread is newly supplied, the thread is tied, and the winding is performed again.

In this way, a plurality of tubes are fed to obtain - full packages. Therefore, the spinning unit of the spinning machine is 50 to 60 times the winding unit of the winder.
If the weights are matched, the spinning process and rewinding process will operate more efficiently as a whole.

When performing high-mix, low-volume production under the above-mentioned relationship,
In the conventional system, each spinning machine produces different types of yarn,
The chain thread is wound back on one wine goo. Therefore, for example, if six types of thread are produced on five spinning machines with 400 spindles and are rewound on five wine goos, one wine goo will be used to rewind the chain thread. The number of spindles in the winding unit is about 12, and each wine goo must be equipped with a drive source, a blower, etc., which is extremely uneconomical, and depending on the arrangement of the wine goos, it may be disadvantageous in terms of space. be.

In order to solve the above problems, there is a system disclosed in Japanese Patent Laid-Open No. 17464/1983. That is, a wine goo having a large number of winding units is substantially divided into a plurality of sections, one section is supplied with a type of pipe yarn produced by a spinning machine and wound thereon, and another section is supplied with a type of pipe yarn produced by a spinning machine and wound thereon. In addition to supplying a type of yarn produced by a spinning frame, a yarn supply path and an empty bobbin return path are provided between each section and the spinning machine to create a closed loop, so that different types of yarn can be This is an automatic yarn transport system that prevents the yarn from being supplied to the winding unit.

In such a system, it is important to be able to automatically supply the same type of yarn to the same winding unit without error, without having to configure each winding unit to have a yarn storage magazine. becomes.

Regarding this point, we focused on the tray that circulates between the spinning machine and the winder and conveys the pipe yarn, and by attaching an identification mark indicating the type of pipe yarn on the outer peripheral surface of the disc-shaped base, it is possible to Based on the identification of the spinning machine that produced the pipe yarn, a sensor is installed on the entrance side of the branch path between the main supply path and the winding section to read the identification mark, and a pipe yarn selector is installed to control the intake into the branch path. On the other hand, it is known to provide a sensor for reading the identification mark and a bobbin selector in the branch return path between the return path and the spinning machine (Japanese Utility Model Publication No. 186011/1983).
.

[Problem to be solved by the invention] However, if the tray identification mark is simply read by a sensor as in the above method, although the combination of the tray and bobbin is correct, it is possible that a different type of yarn may be mixed in due to a malfunction of the yarn selector. It is not possible to detect cases where a different type of yarn is conveyed on the correct tray because the bobbin is incorrectly combined with the tray in the winding section. If even one yarn of a different yarn type is wound in the winding section,
There is a problem in that the rolled up package becomes a defective package.

It is impossible to visually detect contamination in a package rolled up in this way, so it is only possible to detect contamination with different types of yarn by finding defects that appear in the fabric woven using this bread gauge yarn. be discovered. For this reason, conventionally, bobbins of different colors are used for the tube yarn depending on the thread count to prevent number five.

However, if the combination of the tray and bobbin is incorrect as mentioned above, different types of yarn will be mixed in the package, and all doffed bread gauges will be defective or will be removed as defective. If not, it will have a negative impact on the subsequent knitting process.

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems, and it is an object of the present invention to provide a number five prevention device that prevents number five by identifying the color of a color bobbin.

[Means for Solving the Problems] The fifth prevention device of the present invention divides a large number of winding units arranged side by side forming a winding into a plurality of winding sections,
A yarn conveyance system that winds multiple types of yarn in these winding sections and supplies yarn to these winding sections using a common main conveyance line and circulation delivery paths for each winding section that branch out from the common main conveyance line. In the bobbin circulation delivery path of each winding section, there is a color sensor that detects the color of the color bobbin of the yarn, and a color sensor detects the color detected by the color sensor. It is constructed by providing a determining means for emitting a signal when the color is different from the seed color, and a means for stopping the operation of at least the circulating delivery path of the winding section in response to the signal from the determining means.

[Operation] The color sensor detects and monitors the color of the color bobbin of the yarn passing through the yarn circulation delivery path of the winding section to which it belongs. When the color sensor detects a color different from the color of the yarn type handled by the winding section, a signal is generated from the determination means, and this signal causes at least the operation of the circulation route of the winding section to be stopped.

For this reason, if a pipe yarn of a different type to the relevant winding section is conveyed on the correct tray for the relevant winding section, or if the wrong pipe yarn is conveyed to the relevant winding section on the wrong tray. In any case where the yarn is transported on a certain tray, the operation of the circulation delivery path is stopped, so that the mixed pipe yarn can be pulled out from the tray and removed. This prevents an accident in which threads of different types are mixed into the package and wound up.

[Example] Hereinafter, a case where an example of the present invention is used in a system for supplying and conveying various kinds of pipe yarns to a Veg tray will be described with reference to the drawings.

In FIGS. 1 and 2, the automatic winder W is configured with a large number of winding units 1 (FIG. 3) arranged in parallel, and in the case of this embodiment, there are substantially five winding sections SCI to SC5. be divided.

Supplying the yarn to the winder W and carrying out empty bobbins, etc.
This is carried out by the main conveyance line 2 in a closed loop. Both ends of the main conveyance line 2 are pipe yarn supply paths 3 to the winder W.
and the bobbin return path 5, and the tube yarn supply path 3 connects each winding section SCI to S05 via branch supply paths 3a to 3e.
It is connected to a dedicated circulation route 4.

As shown in FIG. 3, from the pipe supply path 3 to the branch line 3a
A gate 7 is provided at each branch point to the branch line 3a to 3e, and a tray sensor 6 provided immediately before the gate 7 connects the branch line 3a to 3e.
It is designed to open and close the entrance to. In addition, in the middle of the circulation delivery path 4 in each winding section S01 to SC5,
A fifth detector consisting of a position sensor 8 and a bobbin collar sensor 9 is provided.

Along the main conveyance line 2, a bobbin processing zone 10, a yarn supply zone 11, and a yarn end outlet device 12 are arranged in order in the direction of conveyance of a conveyance medium (hereinafter referred to as a tray).

The bobbin processing zone 10 includes a bobbin processing device 13.1.
4.15 is installed in the middle of the main conveyance line 2. The bobbin processing device 13 is of a type that can sort two types of bobbins a and b into empty bobbins and bobbins with very little remaining yarn, and the device 14 can similarly process other types of bobbins c and d.
The apparatus 15 separates the remaining one type of bobbins into empty bobbins and bobbins with very little yarn remaining.

Furthermore, in the pipe yarn supply zone 11, a branch line 16 that branches off from the main conveyance line 2 and joins the same conveyance line 2 again has a number of types of pipe yarns (in this embodiment, five types).
A number equal to . Pipe supply stations P1 to P5 are provided in the middle of each branch line 16, station P1 supplies the pipe a, station P2 supplies the pipe, station P3 supplies the pipe C, and station P4 supplies the pipe. At station P5, the tube yarn e is supplied and inserted into the tray for each yarn ring.

The tray that has completed the supply of yarn in zone 11 or the tray that has passed the bobbin with residual yarn is placed in the main conveyance path 2.
After being transported in the direction of arrow P, supplied to a common threading device 12, and subjected to a threading action, the various kinds of pipe yarns are transported on the line 2 toward the winder W in random order.

Each pipe yarn b to e passes through the branch supply path 3a, and the pipe yarn d is transferred from the branch path 3d onto the delivery path 4 of section SC4, and so on. It is supplied to

In each section, as shown in FIG.
When the yarn 17 is transferred to the tray 18, the winding unit 1
The yarn transfers onto the rotating disk 19, enters the standby groove 21 through the yarn intake port 20, and reaches the rewinding position 22. In this way, the subsequent pipe yarns enter the pipe yarn waiting groove 21 one after another, and when the waiting groove 21 is filled with a predetermined number of pipe yarns, the pipe yarns sent after that cannot enter the waiting groove, and the pipe yarn is goes from the surplus pipe yarn feeding port 23 to the next winding unit.

In this way, the trays in which the yarns are inserted are sequentially filled starting with the winding unit closest to the take-out device 12. However, when a vacant space occurs in the yarn waiting groove 21, the vacant space is filled in order from the winding unit closest to the winding unit 12. It's being buried.

A relay pipe 124 waiting above the pipe yarn 17 at the rewinding position 22 sucks and holds the blown-up yarn end, rotates it upward, introduces it into the yarn splicing device, and rotates it with a traversing drum 25. The yarn end on the package 26 side and the yarn end on the tube yarn 17 side are spliced, and rewinding is started.

In addition, if the yarn splicing fails, the yarn splicing operation will be automatically restarted.
However, if the yarn splicing fails a predetermined number of times, for example three times in a row, the yellow button 27 will protrude and the winding unit 1 will stop its operation. 28 is a start switch after doffing the package 26.

In Figure 1.2, each winding section S of the winder W
Empty bobbins of various types, bobbins with very little remaining yarn, and bobbins with residual yarn discharged randomly onto the bobbin return path 5 from C1 to SC5 are transferred onto the main conveyance line 2,
First, in the bobbin processing zone 10, bobbins with very little remaining yarn and empty bobbins are removed from the tray, and placed in a box 8.
It is accommodated in 1 to B5.

Therefore, among the various types of j-lays that have passed through the bobbin processing zone 10, only empty trays without bobbins or trays with bobbins with residual yarn that can be resupplied to the winder are transported.

Subsequently, when reaching the tube supply zone 11, each branch runin 16
A tray sorting device 29 provided on the inlet side of the tray takes the types of trays belonging to each station P1 to P5 into the branch line 16 according to the height position of the annular vortex provided on the tray circumferential surface, and transfers them to the pipe supply station. It is transferred toward P1 to P5. When the tray reaches a predetermined position at the station, the tray is stopped by a stopper (not shown), and the presence of the tray is detected.
After the sensor confirms that there is no bobbin on the tray, the yarn supply devices at stations P1 to P5 operate for one cycle, and the new yarn on the conveyor located above is fed and inserted onto the empty tray. .

When the yarn is inserted, the upper bobbin non-confirmation sensor indicates that a bobbin is present, the stopper is released, and the tray with the specified yarn inserted is further transported on the branch line 16 in the direction shown in FIG. , joins the main conveyance line 2, and is transported along the line 2 toward the yarn guide device 12. Incidentally, when there is a bobbin with residual yarn on the tray that has reached the above-mentioned yarn supply stations P1 to P5, the bobbin passes through without being supplied with the yarn and heads toward the pick-up device.

In this way, the tray with the tube yarn inserted therein is transported on the conveyance path 2 and is supplied to the pick-up device 12, where the yarn ends are pulled out.
The pipe yarn is suspended from one end of the core tube into the core tube, and is conveyed toward the winder W.

In the winder W, the various trays randomly conveyed on the main supply line 2 in FIG. be done. The branch roads 3a to 3
A tray sensor 6 consisting of a magnetic cord and a proximity switch, or a reflector cord and an optical sensor is installed on the input side of e, and a specific tray identified by the tray sensor 6, that is, a pipe , and are automatically sorted and supplied to a specific winding section according to the opening and closing of the gate 7.

Next, FIG. 5 shows an example of the oval configuration of the tray sensor 6, position sensor 8, and bobbin color sensor 9.

In FIG. 1, the lower end of the tube yarn 17 wound around the color bobbin 30 is inserted into the tray 18, held in an upright state, and conveyed to the winder W by the tray 18. In the example shown in FIG. 5, the tray sensor 6 for identifying the type of the tray 18 and the type of the pipe thread 17 is a plurality of iron rings 32, 33 provided on the circumferential surface of the disc-shaped base 31 of the tray 18.
Proximity switch 34.35 for detecting an identification mark consisting of
A position sensor 8 for obtaining the bobbin position, that is, the fifth identification timing, consists of a projector 8a
and a light receiver 8b, whose optical path is blocked by the upper part of the bobbin 30 to detect the bobbin. Bobbin 3
Specifically, the bobbin color sensor 9 for identifying the type of color of the bobbin 2 and the count of the yarn 17 includes a light projector 36 that irradiates light onto the upper peripheral surface of the bobbin 2 and a light receiver that receives the reflected light. It consists of a receiver 37 and an electric circuit section (see Figure 3) for receiving a signal from the light receiver 37 and identifying the color of the bobbin.

The position sensor 8 and bobbin color sensor 9 that constitute the fifth detector operate as follows. When the pipe thread 17, which has m rings around the circulation distribution path 4, comes to the position of the fifth detector, the optical path of the position sensor 8 is blocked by the side of the bobbin 30 of the pipe thread 17, and the bobbin color sensor 9 detects this position. Exactly color bobbin 30
You will be in a position where you can see the diameter line. At this point, the bobbin color sensor 9 reads the color of the bobbin 30, and the color is determined by the winding sections SCI to SC5.
A fifth detection circuit (determination circuit 51 in FIG. 8) determines whether or not the color belongs to the color. That is, the color to be detected by each bobbin color sensor 9 is determined in advance for each winding section SCI to SC5, and when a color bobbin 30 of a color different from that color is detected, the color to be detected by each bobbin color sensor 9 is determined in advance for each winding section SCI to SC5. It is determined that the pipe thread that should go there is mistakenly mixed in, that is, number five.

As shown in FIG. 6, when No. 5 is detected by the bobbin color sensor 9, a No. 5 detection signal to that effect is sent to the pick-up device 1.
2, and the operation of the pick-out device 12 is stopped. This is because the conveyance system of the pick-out device 12 rotates an independent disk, so the supply of new pipe yarn from the pick-out device 12 is stopped to prevent the pipe yarn from clogging on the conveyance line 2. This is to prevent this.

The pick-out device 12 stops the above-mentioned operation when receiving the fifth detection signal, and may be provided in itself or in a fixed length device! The ζζ clamp, for example, the product name Patlight, is turned on to display the trouble number, that is, the name of the winding section where No. 5 was detected. Further, upon receiving the fifth detection signal, the winder W
A signal is sent to the main body of the length fixing device, and the entire conveyance system of the winder W, that is, the conveyance line 2, the pipe supply path 3. Circulation route 4
Stop the series of transport systems including. However, since the conveyor is installed through the entire winder,
This simply means that the entire conveyance system of the winder is stopped.If a conveyor is provided independently for each winding section SC1 to SC5, the conveyor of the winding section to which the bobbin color sensor 9 that detected No. 5 belongs can be independently set. It can also be stopped.

Through the above control, the operator finds the yarn of a different colored bobbin mixed in the circulation delivery path 4 of the designated winding section from among the yarn of the stopped conveyance system, and pulls it out from the tray 18. After that, press the reset button provided on the color sensor section. As a result, the above-mentioned warning lamp goes out, the trouble number display is cleared, and the operation of the stopped conveyance system is restarted.

By the way, even if the conveyor is stopped, winding continues, so
If the operator does not perform any processing for a long time, the winding unit 1
In this case, the pipe yarn 17 runs out, and the yarn splicing failure operation is repeated, and at the third time, the yellow button 27 protrudes, indicating that yarn splicing is not possible.

Therefore, if the yellow buttons protrude from many winding units, the operator will have to perform an extra task of pressing the yellow button for each winding unit to restart the operation. Therefore, if the transport system does not resume operation even after a predetermined set time has passed after stopping the transport system, it is necessary to issue a thread splicing prohibition command to prevent the winder from splicing. be.

FIG. 7 shows the outlet device 'I!' in the main conveyance line 2.
, 12, a number detector consisting of a tray sensor 6, a position sensor 8, and a bobbin color sensor 9 is arranged. This fifth detector detects the appropriateness of the combination of the colors of the tray 18 and the color bobbin 30 in the main conveyance line 2, and determines the yarn type indicated by the color of the tray 18 and the color of the color bobbin 30. If this occurs, it is determined to be number 5, and the entire conveyance system of the winder is stopped in the same manner as above, and the pipe yarn 17 having a different combination of tray 18 and color bobbin 30 is removed. This prevents number 5 regarding all winding sections SCI to SC5 in advance and in common.

However, the fifth detector only detects the suitability of the color combination of the tray 18 and the color bobbin 30, and does not detect whether the tray is correctly accommodated in the predetermined winding sections S01 to SC5. Cannot be determined, i.e. gate 7
Depending on the operation of
There is a risk that it will be taken into account. Therefore, even in this case, it is necessary to arrange a fifth detector for detecting the color of the color bobbin 30 in the circulation delivery path 4.

FIG. 8 shows an electrical circuit portion of the bobbin color sensor 9.

In FIG. 8, the three light receiving elements 38 of the light receiver 37 separate the reflected light from the color bobbin 30 into the three primary colors of red, blue, and green, and pass through an amplifier to produce red.

The luminance component SO is extracted from the three adders as the sum of the blue and green hue components Ro, BO, and Go.9 These hue components Ro, Bo, Go, and luminance component So are all analog signals, and each It is input to an independent comparator 40.

Each comparator 40 receives these input signals RO, BOGO,
The level setter 41 compares the input signals Ro, Bo, .

When SO is larger than the set value, color information signals "with color components" are output at R, B, G, and 5t-H levels. Further, an inverter 42 is connected to each comparator 40,
From each inverter 42, the color information signals R, B, G, S
Color information signals π, B, G, S with “no color components” that are inverted
is output.

No. 8 R, B, and G are output from the color bobbin 30 without color information of "color components present" for red, blue, and green hue components.
is a reddish, bluish, greenish color that is more than the set value, and the color information signal S with "color component present" for the luminance component is output when the color bobbin 2 A color whose overall color is brighter than the setting value, such as "pink"
This is the case with colors such as ``bright green'' and ``pale blue.'' And color information signals R, B, and G with "no color components".

S is output when the red, blue, green, and luminance components are not included in the color bobbin 2 up to a certain level. Color information signals “with color components” R, B, G,
The rising edge of one of the output signals S can be used as an identification timing for detecting color information signals R, B, G, and S with "no color components."

43 uses the red, blue,
4 systems of green and FF degrees, total of 8 color information signals R, B, G,
This is a color information selection circuit that determines which color information of S, R, B, G, and S should be selected or combined for determination processing.

44 is the above four systems in the color information extraction circuit 43, a total of 8
This is a color system designation circuit that selects or combines the three color information signals R, B, G, S, R, [3, C, and S, that is, the color system to be used for identification, and is red.

It is equipped with an independent color system designation switch 45 corresponding to four systems of blue, green and one brightness. From each color system designation switch 45, designation signals r, b, g, and s are outputted in trubels to determine whether the color components of red, blue, green, and luminance are present.
Further, an inverter 46 is connected to the color system determination switch 45, and each inverter outputs the specified signals r,
71 designation signals specifying the color components of red, blue, green, and brightness, which are the inversions of b, g, and s, are output at the t level.

When one of the color system designation switches 45, for example, an R color system designation switch, is turned on to designate red, an AND gate 47 belonging to the designated red system is opened by the designation signal. At this time, the designated signal F remains at L level, so
AND gate 48 is in a closed state. And O
For the remaining color system designation switches 45 that have not been set to N, the group of AND gates 47 is closed, and the AND gate 48 is closed.
The group becomes open by the designated signals s, g, and s.

That is, 8 color information signals of 4 systems R, BG, S, R,
Out of B, G, S, 4 systems 4 color information signals R, B, G
, S are collected. This means that the color system specifying circuit 44 specifies a red color, which has a red hue and does not have color information of blue, green, or brightness, as a color for identifying the color bobbin 2 to be inspected. Attributable to If the number of color system designation switches 22 to be operated is increased and, for example, red and blue are designated by turning on the color system designation switches 22 and 23, 4
Four color information signals R, B, G, and S are collected, and a "purple color" color having red and blue hues and no green and brightness color information can be specified. Similarly, various color systems can be specified.

Reference numeral 49 denotes a color information exclusion designation circuit for eliminating color information signals of color systems that are not desired to be used among the four color information signals of the four systems taken out from the color information removal circuit 43; An independent manual exclusion switch 50 is provided for each of the , green, and FF systems. For example, if the 4 systems/1 piece of color information taken out from the color information extraction circuit 43 (No. 8 is the above-mentioned four RB, GS, if only the three exclusion switches 50 on the right side are turned on, blue, green , the three luminance color information signals B, G, and S are removed and ignored from the determination elements, and only the red color information signal R remains as a valid processed signal for the leftmost exclusion switch 50 that was not turned on. Therefore, it is possible to specify a pure “red color” color, whether it has a red hue or not.

Reference numeral 51 is a determination circuit for determining whether the color bobbin 2 is of the correct color, and a color information discarding circuit 20
4 systems of color information signals extracted from the 4 systems or 3 to 1 systems of color information signals excluded from this by the color information exclusion designation circuit are received as color information to be finally judged, and the color information of these 4 to 1 systems is received as color information to be finally judged and processed. Based on the signal, it is determined whether the color bobbin 2 is of a certain color or not.

Next, the operation will be explained using the embodiment shown in FIG. 3 as an example.

For convenience of explanation, color bobbin 2 has two colors, “red” and “purple”.
Seeds are used, number 14 for red bobbins and number 1 for purple bobbins.
It is assumed that a number 6 thread is wound thereon, and both color bobbins 2 are supplied to the circulation distribution R4 of separate winding units SCI and SC2, respectively.

In such a case, in order to identify whether or not the color bobbin 30 is the correct color bobbin for the winding unit SCI, SC2, it is necessary to distinguish between the two colors of the color bobbin 30, "red" and "purple". It is necessary to distinguish between them. However, the problem here is that red and purple contain red as a common hue, so the method of identifying whether the two color bobbins 2 are correct or not based on the presence or absence of the red color component does not allow accurate identification. This is something that cannot be done. Therefore, "blue" is included in "purple" of one color bobbin 2, but not included in "red" of the other color bobbin 2.
The color component of is used as a measure for determining whether the color bobbin 2 is correct or not.

First, regarding the first winding unit SCI that handles the red bobbin (thread number 14), it is detected that the "blue" color component does not reach a certain level, and therefore the color information signal B is generated. is the criterion for determining whether the bobbin is a correct color bobbin. (H, the output of the B inverter 42 is at level 14 even though the color bobbin 30 has not yet reached the position of the bobbin color sensor 9, and the color information signal B is generated, so check whether the above conditions are correct or not. A second condition is required as the identification timing to judge when the color bobbin 30 is at the position of the bobbin color sensor 9. Detection by sensor 8 is sufficient.

However, it is also possible to use the brightness information signal S and determine that the color bobbin 30 has come to the position of the bobbin color sensor 9 based on the generation of the brightness information signal S.

Therefore, by turning on the color system designation switch 45 for brightness S in the color system designation circuit 44, the color information signal S indicating that there is a color component of brightness is designated.

Further, by keeping the blue B color system designation switch 45 in the OFF state, the color information signal B indicating that there is no blue color component is designated by the designation signal. Then, turn on the exclusion switch 50 for the four red and green color information exclusion designation circuits.
Then, the red and green input terminals of the four-man AND gate 52 of the judgment circuit 51 are always held at H level, and the red color [? 11 signals R, R and green color information signal G
, are removed from the judgment factors.

With this setting, the AND gate 52 of the determination circuit 51 will only detect when the color = tff information signals S and B are input at the same time, that is, the red bobbin on which the 14th thread is wound has arrived. Only in this case, the output from the "output" terminal at H level can be treated as a detection signal indicating that the color of the color bobbin 2 is correct. If a purple bobbin with 16th thread wound thereon comes by mistake, the comparator 40 outputs the blue color information signal f3, and the inverted color information signal B disappears, so the AND gate The logic of 52 no longer holds true, and its output becomes L level.

The L level output of the AND gate 52 is sent as a conveyance stop signal to the main conveyance line 2 in order to prevent the operator from removing the color bobbin 30 from the conveyance system.

Next, regarding the second winding units 1 to SC2 that handle the 16th thread (purple bobbin), it is detected that the "blue" color component is up to a certain level, that is, the color information signal B The occurrence of this is a condition for determining that the bobbin is a correct color bobbin.

The second condition regarding the identification timing handled in the first winding unit SCI, that is, the condition that the color bobbin 30 is at the position of the bobbin color sensor 9, is the condition that the color bobbin is the correct color bobbin. Although this is not necessarily necessary as a discrimination condition, it is necessary to determine that the color bobbin is incorrect.

Therefore, the second winding unit is set as follows.

First, turn on the blue color system designation switch 45 (B>,
A color information signal B indicating that there is a blue color component is designated by the designation signal. In addition, the brightness color system specification switch 45 (S)
is turned ON, and the color information signal S indicating that there is a color component of luminance is specified by the designation signal S. Further, the exclusion switches 50 (red, green) of the color information exclusion designation circuit 50 are selectively turned on to maintain the red and green inputs of the determination circuit 51 at the 14 level at all times, and the red and green color information is Signal π, R1τ.

G is removed from the judgment factor.

By setting in this way, A of the determination circuit 51
The output terminal of the ND gate 52 becomes H level only when the color information signals S and B are input simultaneously, that is, only when a purple bobbin on which the 16th thread is wound arrives. If you accidentally receive the 14th red bobbin, use the comparator 40
In (B), the blue color information signal B disappears, so A
The output of the ND gate 52 becomes L level. Therefore, AND
When the output of the gate 52 is at the 1r level, it is the correct 16th purple bobbin, so it is passed through, and when it is west, at the L level, it is the 14th red bobbin that was sent by mistake, so it is transported. The main conveyance line 2 is stopped in order to be discharged from the system.

The above example uses red and purple bobbins, but the method for identifying color bobbins of one color that has the same hue component is also the same, and among the color components of red, blue, green, and brightness, By using a color component that is easy to identify as the identification color, it is possible to distinguish and detect both color bobbins without error. The easy-to-identify color components that should be used as identification colors are mostly hue components that are not common to both color bobbins, as seen in the example above, but they also include brightness colors such as white and black. In some cases, it may be easier to identify by using color components, so the luminance color component is also included in the color components that should be used as identification colors and are easier to identify. In any case, by using an easily distinguishable color component different from the actual color of the color bobbin as the identification color, even bobbin colors of the same color system can be distinguished and detected without error.

[Effects of the Invention] As described above, according to the present invention, when the color sensor detects a color different from the color of the yarn type handled by the relevant winding section, the circulation route of the relevant winding section is changed. Since the operation is stopped, the mixed pipe yarn can be removed by the operator. This prevents an accident in which yarn of a different type is mixed into the bread gauge and wound up.
