Description

Description: TECHNICAL FIELD The present invention relates to a mixed number prevention system using a color identification system of a color bobbin sensor and a tray identification system useful in an automatic winder or the like.

[Prior Art] Generally, a tubular yarn obtained by winding a yarn spun by a spinning machine is rewound into a package having a size and shape suitable for removing a yarn defect portion or for a post-process. The automatic winder used in this rewinding process has a single winder configured by arranging winding units with a large number of weights side by side, and the yarn drawn at high speed from the tubular yarn supplied to each unit is rotated by a drive drum. When the yarn of one tubular yarn is used up, the next tubular yarn is newly supplied to perform yarn knotting, and the yarn is wound again.

In this way, a plurality of yarns are supplied to obtain one full-wrap package. Therefore, if the spinning unit of the spinning machine corresponds to 50 to 60 spindles with respect to one winding unit of the winder, the spinning process and the rewinding process can operate efficiently as a whole.

Under the above-mentioned relationship, when performing high-mix low-volume production, the conventional system produces different kinds of yarn for each spinning machine, and rewinds the yarn with one winder. Therefore, for example, if 6 kinds of yarns are produced by 400 spindles with 5 spinning machines and are rewound by 5 winders, one winder winding unit has about 12 spindles, and each winder Since it is necessary to install a drive source, a blower, etc., it is extremely uneconomical, and it is also disadvantageous in space depending on the arrangement of the winder.

In order to solve the above problems, there is a system disclosed in JP-A-59-17464. That is, a winder having a large number of winding units is substantially divided into a plurality of sections, one section is fed with a kind of yarn produced by a spinning machine and wound, and another section is separated. In addition to supplying a kind of yarn produced by a spinning machine, a yarn supplying path and an empty bobbin return path are provided between each section and the spinning machine to form a closed loop, and different types of yarn are wound in the same winding. It is an automatic yarn transfer system that prevents it from being supplied to the take-up unit.

In such a system, it is important that each winding unit can automatically supply the same type of yarns to the same winding unit without error, without having to configure each winding unit with a yarn storage magazine. .

In this regard, paying attention to a tray that conveys the yarn through the spinning machine and the winder, and by attaching an identification mark indicating the type of the yarn on the outer peripheral surface of the disc-shaped substrate, The spinning machine from which the yarn is produced is specified, and a sensor for reading the identification mark and a yarn thread selector for controlling the incorporation into the branch passage are provided on the entrance side of the branch passage between the main supply passage and the winding section. On the other hand, it is known that a sensor for reading the identification mark and a bobbin selector are provided on the branch entrance side of the branch return path between the return path and the spinning machine (Japanese Utility Model Publication No. 62-18604).

[Problems to be Solved by the Invention] However, it is not possible to detect the case where the bobbin combination with respect to the tray of the winding section is incorrect only by reading the identification mark of the tray with the sensor as in the above method. Therefore, there is a problem that another yarn type is wound in the winding section during winding.

Usually, it is difficult to identify the difference in yarn count by visual inspection. Therefore, different color bobbins are used for the bobbin of the tubular yarn to prevent mixed numbers. .

However, if the mixed number cannot be detected and it is wound into the package, different types of yarns will be mixed in the package, and all the doffed packages will be defective or defective. If it is not extracted, it will adversely affect the subsequent knitting process.

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems, and a tray for a color discrimination method of a color bobbin sensor that can accurately perform color discrimination of a color bobbin that is important in preventing mixed numbers is provided. It is intended to provide a mixed number prevention method which is used in combination with the identification method of No. 1 for more reliable prevention of mixed number.

[Means for Solving the Problems] In the mixed number preventing system of the present invention, color bobbins of different colors are used for a plurality of types of yarns produced by a spinning machine, and these yarns are used as yarn types. A tray sensor that reads the identification mark of the tray is attached to the tray with a different identification mark for each, and in order to branch-feed the trays with these plural types of tubing to the winding unit of the yarn type in the winder. A color bobbin sensor for identifying the color of the color bobbin is provided upstream of the tube thread selector, and the tube thread selector is operated according to the identification result, and if the tray identification mark identification result and the color bobbin color identification result are If they are different, the tray is prohibited from being taken into the winding unit.

[Operation] The tray sensor identifies the identification mark of the tray, and at the same time, the bobbin color sensor identifies the color of the color bobbin mounted on this tray. As a result of the identification, if the yarn corresponding to the winding unit is given an operation command to the yarn selector, and if the tray identification mark identification result and the color bobbin color identification result are different, Take-up to the winding unit is prohibited.

Hereinafter, the present invention will be described based on the illustrated embodiments.

In FIG. 1, reference numeral 1 is a tubular thread wound around a bobbin 2,
Reference numeral 3 is a tray for inserting the lower end surface of the tube yarn 1 and conveying it to the winder in an upright state. Reference numeral 4 denotes a tray sensor for identifying the type of the tray 3, and thus the type of the yarn 1, specifically, it comprises a plurality of iron rings 6a, 6b provided on the peripheral surface of the disk-shaped substrate 5 of the tray 3. It is composed of proximity switches 7a and 7b for detecting an identification mark. Reference numeral 10 denotes a bobbin color sensor for identifying the type of color of the bobbin 2, and thus the count of the thread 1 and the like. Specifically, the projector 8 for irradiating the upper peripheral surface of the bobbin 2 with light and its reflected light It comprises a light receiver 9 for receiving light and an electric circuit portion for receiving a signal from the light receiver 9 and identifying the bobbin.

In FIG. 2, the light receiver 9 comprises three light receiving elements 9a, 9b, 9c.
Are arranged on a plane. The reflected light from the color bobbin 2 is separated into the three primary colors of red, blue, and green by the light receiving elements 9a, 9b, 9c. The hue components R ₀ , B ₀ , G _{0 of} are extracted. Also, the hue components R ₀ , B ₀ , G _{0 of} these three primary colors
The luminance component S ₀ is extracted from the adder 11 as the sum of These hue components R ₀ , B ₀ , G ₀ and the luminance component S ₀ are all analog signals and are independent comparators 12, 13, 1 respectively.
Input to 4,15.

Each of the comparators 12 to 15 receives these input signals R ₀ , B ₀ , G ₀ , S.
₀ is compared with the preset values set by the level setters 120, 130, 140, 150, respectively, and if the input signals R ₀ , B ₀ , G ₀ , S ₀ are larger than the preset values, the color information signal R of “with color component” , B, G, S
Is output at H level. Further, inverters 16, 17, 18, and 19 are connected to the comparators 12, 13, 14, and 15, respectively.
From 6 to 19, color information signals of "no color component", which are the inversions of the color information signals R, B, G, S, are output.

The color information signals R, B, G of “with color components” for the hue components of red, blue, and green are output because the colors of the color bobbin 2 are reddish, bluish, and greenish above the set value. In the case of a tinged color, and the color information signal S of "color component present" for the luminance component is output, the entire color of the color bobbin 2 is a tone having a tone brighter than a set value, for example, "pink"
This is the case for colors such as "bright green" and "pale blue". The color information signal of "no color component" is output when each color component of red, blue, green, and luminance is not included in the color of the color bobbin 2 to a certain level. . 1 of the color information signals R, B, G, S that "has color components"
The rising of one output is the color information signal of "no color component",
,,, can be used as an identification timing for detecting.

The reference numeral 20 indicates the color of the color bobbin 2, that is, the type of the thread, whether or not it is correct for the winder unit, and as a deciding factor of the judgment, the above-mentioned four systems of red, blue, green and luminance, a total of 8 Two color information signals R, B, G, S ,,,,
This is a color information sorting circuit that determines which color information of which is selected or combined to perform determination processing. Reference numeral 21 denotes the above-mentioned four systems in the color information sorting circuit 20, a total of eight color information signals R, B, G,
A color system designating circuit for designating a color system to be used for selection or combination of S, ..., That is, identification, and an independent color system designating switch 22 corresponding to four systems of red, blue, green and luminance. , 23,24,25. From the color system designation switches 22, 23, 24, 25, designation signals r, b, g, s for designating "with color components" of red, blue, green and luminance are taken out at H level. Further, inverters 221, 231, 241, 251 are connected to the color system designating switches 22, 23, 24, 25, and from each of the inverters, red, which is the inversion of the designation signals r, b, g, s,
Designation signal that designates "no color component" of blue, green, and brightness,
,, are output at the H level.

The color information sorting circuit 20 is specifically compared with an AND gate 201 which receives two inputs of a red color information signal R from the comparator 12 and a red designation signal r from the color system designation switch 22. Blue color information signal B from device 13 and color system specification switch 23
AND gate 202 that inputs two of the blue designated signals b from
And a green color information signal G from the comparator 14 and a green designation signal g from the color system designation switch 24 are input.
It has a gate 203 and an AND gate 204 which receives two of the luminance color information signal S from the comparator 15 and the luminance designation signal s from the color system designation switch 25. These AND gates 201 to 204 are opened by the designation signals r, b, g, s from the color system designation switches 22 to 25, and the comparators 12 to 15 are used for red, blue, and
When each of the green and luminance components is detected and the color information signals R, B, G, S of "with color components" are output, the detected color information signals R, B, G, S are passed.

Further, the color information sorting circuit 20 includes a color system designation switch 22
AND gates 205, 206, 207, 2 opened by the designated signal which becomes H level when ~ 25 is not selected,
08 is provided, and each of the AND gates 205 to 208 passes the color information signal of “no color component”, ..., When it is output.

Therefore, when one of the color system designating switches 22 to 25, for example, the color system designating switch 22 is turned on and red is designated, the AND gate 201 belonging to the designated red system is opened by the designating signal r. At this time, the designation signal remains at the L level, so that the AND gate 205 is in the closed state. Then, for the remaining color system designation switches 23 to 25 that have not been turned on, the AND gates 202, 203 and 204 are closed and the AND gate 20.
6,207,208 are opened by the designated signal. That is, the four color information signals R, B, G, S, ...
,, of the four color information signals R,
, Is taken out. This has a hue of red as a color for identifying the color bobbin 2 to be inspected, and the colors of blue, green,
This is attributable to the fact that the color system designation circuit 21 has designated a "reddish" color that does not have luminance color information. When the number of color system designating switches 22 to be operated is increased and, for example, the color system designating switches 22 and 23 are turned on and red and blue are designated, four systems of four color information signals R, B, are taken out, You can specify a "purple series" color that has red and blue hues and does not have green and luminance color information. Similarly, various color systems can be designated.

Reference numeral 26 denotes a color information exclusion designating circuit for excluding a color information signal of a color system that is not desired to be used from the four color information signals of four systems extracted from the color information discarding circuit 20 in this way. Equipped with independent manual exclusion switches 27, 28, 29, 30 for each system of blue, green and brightness. For example, the four color information signals of four lines extracted from the color information sorting circuit 20 are
When the exclusion switches 28, 29, 30 are turned on in the case of the above four R ,, ..., the three color information signals of blue, green and luminance are removed and ignored from the judgment elements and are not turned on. With respect to the elimination switch 27, only the red color information signal R remains as an effective processing signal, and pure "red color" color designation as to whether or not it has a red hue can be performed.

Reference numeral 31 is a determination circuit for identifying whether or not the color bobbin 2 is of the correct color, and the color information signals of four systems extracted from the color information removal circuit 20 or the color information removal designation circuit further removes the four systems of color information signals. The color information signals of the 3 to 1 system are received as the color information to be finally subjected to the determination process, and the color bobbin 2 is received based on the color information signals of the 4 to 1 system.
Identify if is of the correct color. Specifically, the determination circuit 31 is composed of a 4-input AND gate 310 having an input terminal for each system of red, blue, green, and luminance, and OR gates 311, 312, 313, 314 placed in front of each input terminal. The outputs of the AND gates 201 and 205 and the exclusion switch 27 are connected to the red OR gate 311. Similarly, AND gate 202,
The outputs of 206 and the rejection switch 28 are the blue OR gate 312.
The outputs of the AND gates 203 and 207 and the elimination switch 29 are connected to the green OR gate 313, and the outputs of the AND gates 204 and 208 and the elimination switch 30 are connected to the luminance OR gate 314.

 Next, the operation will be described.

For convenience of explanation, two types of "red" and "purple" are used for the color bobbin 2. The red bobbin is 14th and the purple bobbin is 16
It is assumed that a count yarn is wound and both color bobbins 2 are supplied to different winding units. In such a case, in order to identify whether or not the color bobbin 2 is the correct color bobbin for the winding unit,
It is necessary to distinguish between the two colors of the color bobbin 2, “red” and “purple”. However, the problem here is that since red and purple contain red as a common hue, it is determined that the two color bobbins 2 have different color components.
That is, the method of identifying whether the item is correct cannot be accurately identified. Therefore, the color component of “blue” which is included in “purple” of one color bobbin 2 but not included in “red” of the other color bobbin 2 is
It is used as a scale for determining the correctness of.

First, regarding the first winding unit that handles the red bobbin (14th thread), it is detected that the "blue" color component does not reach a certain level, and therefore the color information signal is generated. , Is a condition for determining that the color bobbin is correct. However, since the output of the inverter 17 is at the H level and the color information signal is generated even if the color bobbin 2 is not yet at the position of the bobbin color sensor 10,
A second condition is required as an identification timing for determining whether or not the above condition is satisfied at an appropriate time. In order to satisfy the second condition, the color bobbin 2 is the bobbin color sensor.
The arrival at the 10th position may be detected by a separately provided position sensor. However, here, the luminance information signal S is used, and it is determined that the color bobbin 2 has come to the position of the bobbin color sensor 10 based on the generation of the luminance information signal S.

Therefore, by turning on the luminance color system designating switch 25 in the color system designating circuit 21, an AND is performed by the designating signal s.
The gate 204 is opened and the color information signal S indicating that there is a luminance color component is designated. Also, turn off the blue color system specification switch 23.
By maintaining the state, the AND gate 206 is opened by the designation signal, and the color information signal indicating that there is no blue color component is designated. Then, the red system exclusion switch 27 and the green system exclusion switch 29 of the color information exclusion designation circuit 26 are turned on, and the red and green system input terminals of the 4-input AND gate 310 of the determination circuit 31 are always at the H level. To keep the red color information signal
R and the color information signal G of the green system are excluded from the judgment elements of the judgment.

By setting in this way, the AN of the judgment circuit 31
The output terminal of the D gate 310 becomes the H level only when the color information signals S and are input at the same time, that is, only when the red bobbin wound with the 14th thread arrives. Therefore,
The H level output of the AND gate 310 can be treated as a detection signal indicating that the color of the color bobbin 2 is correct. If a purple bobbin wound with 16th yarn is mistakenly received, the comparator 13 outputs the blue color information signal B, and the color information signal which is the inverted signal thereof disappears.
The logic of the AND gate 310 is not established and the output of the AND gate 310 becomes L level. Therefore, L of this AND gate 310
The level output can be handled as a discharge signal for removing the color bobbin 2 from the transport system, for example, a stop signal for the transport conveyor.

Next, regarding the second winding unit handling the 16th yarn (purple bobbin), it is detected that the "blue" color component has a certain level, that is, the color information signal B is generated. That is the condition for determining that the color bobbin is correct. The second condition relating to the identification timing handled by the first winding unit, that is, the color bobbin 2
The condition that the color bobbin is at the position of the bobbin color sensor 10 is not necessarily required as a condition for determining that the color bobbin is correct, but it is necessary for determining that the color bobbin is incorrect.

Therefore, the second winding unit is set as follows.

First, the blue color system designation switch 23 is turned on, the AND gate 202 is opened by the designation signal b, and the color information signal B indicating that there is a blue color component is designated. Further, the luminance color system designation switch 25 is turned on, and the AND gate 204 is opened by the designation signal s.
A color information signal S indicating that there is a luminance color component is designated. Further, the exclusion switches 27, 29 of the color information exclusion designation circuit 26 are turned on to keep the red and green system inputs of the determination circuit 31 at the H level at all times, and the red and green system color information signals R, G, Is excluded from the judgment factors of judgment.

By setting in this way, the AN of the judgment circuit 31
The output terminal of the D gate 310 becomes the H level only when the color information signals S and B are simultaneously input, that is, only when the purple bobbin wound with the 16th yarn arrives. If the 14th red bobbin arrives by mistake, the blue color information signal B disappears in the comparator 13, and the output of the AND gate 310 becomes L level. Therefore, when the output of the AND gate 310 is the H level, it is the correct 16th purple bobbin and therefore it is passed. On the other hand, when it is the L level, it is the 14th red bobbin sent by mistake. , It can be discharged from the transport system.

In the above, red and purple bobbins are taken as an example, but the method of distinguishing between color bobbins of arbitrary colors having the same hue component is the same, and among the color components of red, blue, green, and luminance, By using an easy color component as the identification color, both color bobbins can be distinguished and detected without error. The color components that should be used as the identification colors and are easy to identify are mostly the hue components that are not common to both color bobbins as seen in the above example, but the luminance color such as white and black In some cases, it may be easier to identify using the components, and thus the luminance color component is also included in the easy-to-identify color components that should be used as identification colors. In any case, by using a color component that is different from the actual color of the bobbin and is easy to identify as the identification color, even bobbin colors of the same color system can be distinguished and detected without error.

In the embodiment of FIG. 2 described above, there is one type of color bobbin to be monitored, but by adding the color information sorting circuit 20, the color system designation circuit 21, and the determination circuit 31 of the same configuration as one set, The correctness of two or more types of color bobbins can be monitored.

3 to 5 show an example in which the bobbin color sensor 10 is applied to an automatic yarn transfer system.

In FIG. 3, different kinds of yarns are produced by the spinning machines SP1 to SP4, the yarns of the spinning machine SP1 are rewound in the winding section SC1, and the yarns of the spinning machine SP2 are wound in the winding section SC2. In addition, one winding section corresponds to each spinning machine. MF is a yarn supplying path, which is composed of a main supplying path F1 from each spinning machine and branch supplying paths f1 to f4 to winding sections SC1 to SC4 of the winder. MR is a return path for an empty bobbin or bobbin with residual yarn, and is composed of a common return path R from the winding sections SC1 to SC4 and branch return paths r1 to r4 to each spinning machine.

An outlet device ACF for ejecting the yarn end of the tubing 1 is arranged at one position of the main supply path F1, and tubing thread selectors 41, 42, 43 are arranged at the respective winding section positions of the main supply path F1. The tray sensor 4 and the bobbin color sensor 10 are arranged near the upstream side of the tray sensor 4 and the bobbin color sensor 10, respectively. On the other hand, a path R1 for supplying the bobbin with residual thread to the feeding device ACF is connected to the return path R via a selector 44, and a minimal residual thread removing device ST for separately removing residual thread from the bobbin with minimal residual thread is provided.
Is arranged. 45 is a bobbin detection sensor with residual thread, 46
Is a bobbin detection sensor with a minimal residual thread. Further, a tray sensor 4 and a tray selector 47 are arranged at the spinning machine positions on the return path R, respectively.

Tubular yarn 1 obtained from each spinning machine SP1 to SP4 is wound on a color bobbin 2 of a different color according to the difference in yarn count, and is mounted on a tray 3 having a different mark for each yarn type, and the main supply path MF The yarns are grouped by yarn type or randomly transferred regardless of yarn type.

The yarn 1 transferred in the direction of arrow 40 is sequentially discharged by the discharging device ACF, and is transferred on the main supply path F1 with the yarn end hanging down to the center hole of the bobbin 2 as shown in FIG. The yarn thread 1 that has failed to be output is again supplied to the output device ACF through the feedback passage 39. The dispensed tube yarn 1 is transported toward the winder W on the main supply path F1 and passes through the tray sensor 4 and the bobbin color sensor 10 located at the position of the tube yarn selector 41.

The tray sensor 4 identifies the identification mark of the tray 3, and at the same time, the bobbin color sensor 10 identifies the color of the color bobbin 2 mounted on the tray 3. As a result of the identification, if the yarn is the spinning yarn of the spinning machine SP1, an operation command is given to the yarn yarn selector 41, and the gate 48 shown in FIG.
And the yarn 1 is transferred onto the branch supply passage f1 and supplied to the yarn delivery passage 50 of the winding section SC1.

Similarly, the yarns of the spinning machines SP2 to SP4 are detected by the tray sensor 4 and the bobbin color sensor 10 of the corresponding winding sections SC2 to SC4 and supplied to the yarn delivery path 50 of each winding section. It For example, as for the yarn from the spinning machine SP4, it passes through the tray sensor 4 and the bobbin color sensor 10 belonging to the yarn yarn selectors 41, 42 and 43 one after another, and the delivery route from the branch supply route f4 of the winding section SC4. Five
Supplied on 0.

In this way, the yarn is supplied to the winding section corresponding to each spinning machine, and in each section, the yarn is taken in from the yarn inlet 52 of each unit 51 shown in FIG. In the state shown in FIG. 5, that is, in the state of being mounted on the tray 3, a predetermined yarn is supplied to the winding position to perform rewinding.

If the combination of the tray 3 and the color of the bobbin of the bobbin thread 1 is wrong, and thus the identification result of the tray sensor 4 and the bobbin color sensor 10 are different, each of the tube thread 1 is identified. Intake into the unit 51 is prohibited, the conveyor is stopped, or the main supply path F1 or delivery path 50
Is discharged to another discharge path. However, this inappropriate removal of the tubing 1 is done by the gate 48 of the tubing selector and the tubing delivery path.
By passing each unit 51 through the 50 and the yarn introduction port 52, it may be sent out to the common return path R. In this case, the tray sensor 4 and the bobbin color sensor 10 are provided in the middle of the return path R. Alternatively, it is possible to detect the improper combination again and discharge from the middle of the return path R to another branch path. Further, although it is possible to prevent the rewinding from being started even if it is taken into each unit 51, it is preferable to increase the operating rate of each unit 51 as much as possible.

The tray 3 of the empty bobbin that has been completely rewound in each unit 51 or the bobbin with residual thread that has been discharged due to the impossibility of thread knotting is transported on the common return path R. At this time, the type of tray 3 transferred, and thus the color of color bobbin 2, is random.

The tray 3 of the empty bobbin having no residual yarn is transferred on the return path R, passed through the residual yarn removing device ST and returned to the spinning machine side, and the tray sensor 4 and the selector 47 operated by the sensor. The empty bobbin of a specific color is returned to the predetermined spinning frame SP1 to spinning frame SP4 by the cooperation of.

In the above-mentioned embodiment, the color information signals of the color components to be used for the discrimination determination are selected from among the eight 4-system statistics of the color information signals R, B, G, S and the color information signals. Regardless of the type of color of the color bobbin 2, the luminance color information signal
It is also possible to omit S, and set it to three systems of red, blue, and green, and to select the color information signals of the color components to be used for discrimination from the six color information signals of these three systems. Further, the color information signals ,, are omitted, and the three color information signals R,
A configuration in which a specific hue component is selected from B and G may be adopted. The identification timing can be easily obtained by using it in combination with another sensor such as the tray sensor 4.

[Effects of the Invention] As described above, the present invention surely prevents the situation where the tray and the bobbin are improperly combined and supplied to the winding section, and the yarns of different counts are wound in the same package. It is possible to avoid the inconvenience.
