[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS.
As shown in FIG. 1, the automatic winder according to the present embodiment has a large number of winding units 1 and a machine that can individually set operating conditions for these winding units 1 and monitor the operation. The stand control device 4 is provided as a one-line machine stand 61. In this embodiment, as shown in FIG. 8, the case where the machine 61 has one line has been described. However, as shown in FIG. By being connected so that data can be transmitted and received by the device, the device may be configured so that it can be centrally managed by the host control device.
[0013]
As shown in FIG. 7, the winding unit 1 is provided with an unwinding assisting device 2 and a twist preventing device in a winding direction of a spun yarn Y wound around a yarn supply package B (yarn supply winding body) such as a spinning bobbin. A tensioning device 3, a yarn splicing device 5, a slab catcher 6, and a driving drum 7 are provided in this order, and a unit control device 50 for controlling these devices is provided. That is, the automatic winder is configured to unwind the spun yarn Y from the yarn supplying package B by the rotation of the driving drum 7 and wind the spun yarn Y around the winding package P which rotates in contact with the driving drum 7.
[0014]
The tension applying device 3 is disposed above the yarn supplying package B via the unwinding assisting device 2 and is a gate type in which movable comb teeth 12 are alternately arranged with respect to fixed comb teeth 11. . Specifically, the comb teeth 12 can be engaged with or released from the comb teeth 11 by a swing lever (not shown), and the degree of the urging force by the swing lever can be changed by a winding tension control solenoid 13. is there. The take-up tension control solenoid 13 generates a rotational urging force according to an electric signal from the unit control device 50. The tension applying device 3 applies a tension according to the urging force applied to the movable comb teeth 12 to the spun yarn Y that is passed between the fixed comb teeth 11 and the movable comb teeth 12 and bent in a zigzag shape. Work. When the voltage (electric signal) to the winding tension control solenoid 13 is reduced, the degree of zigzag of the spun yarn Y is reduced, and the applied tension is reduced. Thus, the applied tension is changed according to the electric signal from the unit control device 50 to the tension applying device 3. Therefore, the control amount for the tension applying device 3 is a voltage (electric signal) for the winding tension control solenoid 13. Further, this voltage value is set in advance according to the winding amount of the winding package P.
[0015]
The yarn splicing device 5 performs a yarn splicing process for joining the spun yarn on the side of the yarn supply package B and the spun yarn on the side of the take-up package P. The yarn splicing device 5 includes a yarn splicing device main body 35, a lower yarn suction guide member 36 that guides the spun yarn on the yarn supply package B side to the yarn splicing device main body 35, and a yarn splicing device on the winding package P side. An upper thread suction guide member 37 for guiding to the main body 35 is provided.
[0016]
The lower thread suction guide member 36 has a freely openable and closable suction port 36a, and is rotatable about a shaft 36b. When the spun yarn is forcibly cut, the suction port 36a is opened, and the tension applying device 3 also serving as a twist preventing device is opened, and the yarn end on the yarn supply side is sucked into the suction port 36a. When the yarn end is held by the suction port 36a and turned from the lower yarn end capturing position to the upper yarn end guide position, the lower yarn is guided into the yarn joining device main body 35 and the tension applying device 3. The lower thread suction guide member 36 has substantially the same posture as that at the time of thread capture. Since the state in which the suction port 36a is located between the yarn supplying package B and the tension applying device 3 is set as the standby position, the yarn end on the yarn supplying side can be quickly captured after the operation of the lower yarn suction guide member 36.
[0017]
The upper thread suction guide member 37 has a suction port 37a and is rotatable around a shaft 37b. When the spun yarn is forcibly cut, the spun yarn turns to the upper yarn end capturing position, and the yarn end wound around the winding package P is sucked through the suction port 37a. Furthermore, the upper thread is guided to the yarn joining device main body 35 by the upper thread suction guide member 37 rotating downward while the upper thread is captured. Then, the yarn splicing device main body 35 splics the upper yarn and the lower yarn.
[0018]
The slab catcher 6 is, for example, a capacitance-type or optical-type yarn thickness detection device, and detects a yarn defect such as a slab by processing a signal from the slab catcher 6 with an analyzer 40. When a yarn defect is detected, the spun yarn Y being wound up is cut by the attached cutter 6a, and the defective portion is removed by the yarn splicing device 5 during the yarn splicing process. And the spun yarn Y on the winding package P side. It is arranged between the yarn joining device 5 and the slab catcher 6.
[0019]
The drive drum 7 is configured as a traverse drum having a traverse groove, rotates the take-up package P in contact with the take-up package P, and causes the spun yarn Y wound on the take-up package P to traverse. . The drive drum 7 is driven by a motor 41 whose rotation speed is controlled by an inverter 42. The rotation speed of the motor 41 is controlled via an inverter 42 by a control signal output from the unit control device 50. A package winding length measuring sensor 43 for detecting the number of rotations of the rotating shaft is provided near the rotating shaft of the motor 41. The package winding length measuring sensor 43 outputs a detection signal to the unit control device 50 for each rotation of the rotation shaft.
[0020]
The above-described unit control device 50 obtains the amount of yarn wound on the winding package P (hereinafter simply referred to as “winding amount”) based on the detection signal of the package winding length measurement sensor 43, and drives the yarn. The drive control of the drum 7, the drive control of the tension applying device 3, the drive control of the yarn joining device 5, and the like are performed. The method for obtaining the winding amount is not limited to the package winding length measuring sensor 43. For example, the yarn speed of the spun yarn Y traveling during winding may be measured, and the speed may be integrated to obtain the winding amount. Further, the unit control device 50 includes a tension applying device 3 at the time of winding, an applied tension storage unit 56 that stores a voltage to the winding tension control solenoid 13, a winding amount storage unit 57 that stores a winding amount, and various types. And a storage unit for storing the processing routine of the above. Further, the unit control device 50 includes a transmission / reception unit, a calculation unit, and the like (not shown). The transmission / reception unit is capable of transmitting / receiving data to / from the machine control device 4 of FIG. The arithmetic unit is capable of executing an interrupt response function and a restoration response function based on the processing routine stored in the storage unit. The interrupt response function is activated when it is necessary to interrupt any processing operation of the winding unit 1 and interrupts the processing operation of the unit. This is because when an interrupt command signal is input from the machine control device 4, it is determined whether or not the command signal is the one that has specified itself. This is a function of transmitting the control amount of the tension device 3, that is, the voltage value and the winding amount to the winding tension control solenoid 13, to the machine control device 4 as operation information. The restoration response function, when a restoration command signal is input from the machine control device 4, determines whether or not the command signal specifies itself, and if the command signal specifies itself, the signal is included in the signal. This is a function of reading out the voltage value and the winding amount for the winding tension control solenoid 13 immediately before the interruption, which are included in the operation information, and restarting the remaining winding with the applied tension.
[0021]
The unit control device 50 is connected to the machine control device 4 so that data can be transmitted and received. The machine control device 4 includes a storage unit 71 and a central control unit 72. The storage unit 71 is composed of a large-capacity storage device such as a hard disk, and has a lot suspension information file 73 and a group configuration information file 74. The lot suspension information file 73 stores a voltage and a winding amount for the winding tension control solenoid 13 immediately before the winding unit 1 stops. The group configuration information file 74 is a group for preliminarily grouping a plurality of winding units 1 in one machine connected to the machine control device 4 by an arbitrary number of units and operating collectively in the group. The configuration is stored. For example, as shown in FIG. 2, when the number of winding units 1 in one machine is 60, the group configuration information file 74 indicates the No. of the winding unit 1. 1 to No. Group 1 (GR1) up to No. 12 and No. 1 of winding unit 1 13-No. Group No. 24 (GR2) and No. 24 of winding unit 1 25-No. Up to 60 are stored as group 3 (GR3).
[0022]
On the other hand, as shown in FIG. 1, the central control unit 72 includes an information processing unit 75 immediately before interruption as information processing unit immediately before interruption, a restoration control unit 76 as restoration control means, and a winding condition command as winding condition instruction means. A unit 83, a display control unit 77, a display unit 78, and an operation unit 79 are provided. The information processing unit 75 immediately before the interruption, the restoration control unit 76, and the display control unit 77 are formed in software by the interruption processing routine of FIG. 3 and the restoration processing routine of FIG. Note that each of the units 75 to 77 may be formed as hardware. Note that there are a plurality of winding conditions according to the kind of the winding package, and for example, parameters such as a winding amount, a tension control amount, and a winding yarn speed of the winding package are different from each other. .
[0023]
The information processing unit 75 immediately before interruption includes a data storage processing unit 81, a determination unit 82, and a winding condition command 83. The data storage processing unit 81 sucks the operation information (voltage and winding amount for the winding tension control solenoid 13) of each winding unit 1 immediately before the interruption of the interrupted group, and stores it in the lot interruption information file 73. ing. The determination unit 82 recognizes and determines the group to be interrupted specified by the operator. The winding condition command unit 83 outputs a winding condition command signal to cause the winding unit 1 of the designated group to execute a winding process based on a winding condition corresponding to a desired product to be produced. It has become.
[0024]
On the other hand, the restoration control unit 76 has a restoration lot determination unit 84, a restoration acceptance search unit 85 as restoration acceptance search means, and a restoration setting unit 86. The restoration lot determination unit 84 recognizes and determines the type (lot) of the restoration target specified by the operator. The restoration receiving search unit 85 searches for a group that can accept the resumption of winding for the kind (lot) to be restored and displays the group on the screen. The restoration setting unit 86 recognizes and determines a group specified by the operator, and a restoration destination that transmits operation information to the above-specified group so as to resume winding in the specified group. And a lot data output unit 88.
[0025]
The operation of the automatic winder in the above configuration will be described.
In the winding unit 1 as shown in FIG. 7, while the winding operation of the spun yarn Y is being performed in each group, for example, it is urgently required to produce a different type of product different from the one currently being wound. When the operator enters, first, the operator forcibly interrupts the winding of a certain group (the winding unit 1) in order to immediately start the urgent winding, and prepares for interruption. Next, as shown in FIG. 1, the operation unit 79 is operated by an operator to issue an instruction for an interruption process. As a result, as shown in FIG. 5, an interrupt processing screen is displayed on the display unit 78. That is, in the display unit 78, the currently operating groups (GR1, GR2, GR3,...) And the type information (LOT- (A) type, LOT- (B) type, LOT) processed in each group are displayed. -(C) type ...) is displayed in a list.
[0026]
Further, as shown in FIG. 3, an interrupt processing routine is executed. Here, the presence or absence of a save operation in the operation unit 79 is monitored (S1). If the save operation is not performed (S1, NO), S1 is repeatedly executed to enter a standby state for the save operation. On the other hand, it is assumed that the operator determines the interrupt destination as one group of the winding units of the group (GR2) and forcibly interrupts the winding of 12 spindles of the group (GR2). Thereafter, as shown in FIG. 5, for example, when the cursor in the interrupt processing screen is moved by the operator and the operation (save operation) is performed to select one group of the winding units of the group (GR2) (S1). , YES), the contents of the save operation are determined (S2), a downward arrow is displayed on the screen below the cursor, and the type information to be stored is displayed below the arrow on the screen.
[0027]
Further, a window for confirming whether or not to save the type information (lot data) of the group is displayed in a pop-up, and the operator's judgment is requested. If the operator gives a command not to save, the process moves to S1 and returns to the standby state for the save operation. On the other hand, when the operator issues a command to save, an interrupt command signal is transmitted, and the voltage to the winding tension control solenoid 13 immediately before the interruption in all of the 12 weights of the selected group (GR2) is applied. And the winding amount is sucked up as operation information (S3). Then, the operation information is stored in the lot suspension information file 73 together with the group number (GR2) and the type information (LOT- (B) type) (S4). Thereafter, the group (GR2), which is the group number, the date and time when the interruption was started, and the like are displayed on the screen on the save list screen formed on the side of the display position of the type information (S5).
[0028]
The winding unit 1 whose processing operation has been interrupted by the interrupt command signal as described above is conveyed to a storage location (not shown) after the winding package P and the yarn supply package B being wound are removed. . Thereafter, the operator inputs a product type (winding condition) to be urgently produced by the operation unit 79 shown in FIG. 1 and designates a group (GR2) for performing the winding process, whereby the winding condition command unit A winding condition command for urgent production is output to the group (GR2) via 83. As a result, in the group (GR2), the interruption of the winding process of another type is executed, and the production of the winding package P is started.
[0029]
Next, when the production of the interrupted product type is restarted, the operation unit 79 shown in FIG. 1 is operated by the operator to issue a restoration processing command. Thus, as shown in FIG. 6, a restoration processing screen is displayed on the display unit 78. That is, in the display unit 78, the currently operating groups (GR1, GR2, GR3,...) And the type information (LOT- (A), LOT- (D), LOT- ( C) ...) are displayed in a list. Here, the type (LOT- (D)) that has been wound in the group (GR2) represents a type that requires an urgent production and is interrupted in place of the type (LOT- (B)). .
[0030]
Further, as shown in FIG. 4, a restoration processing routine is executed. Here, it is determined whether or not the lot as the type to be restored is designated by the operator via the operation unit 79 (S11), and if not designated (S11, NO), S11 is repeated to execute the designation operation. Wait state. On the other hand, as shown in FIG. 6, for example, the cursor in the restoration processing screen is moved by the operator, and the lot to be restored (in this case, the group (GR2) of the storage list screen displayed at the left end number “3” in the screen) is changed. If the selection operation has been performed (S11, YES), the lot designated by this operation is determined as the restoration request lot (S12). Then, the number of weights of the restoration request lot (in this case, 12 weights) is compared with the number of winding units 1 of each group obtained from the group configuration information file 74, and the same number of groups is accepted as a group that can receive the groups. A search is performed (S13), and the search result is displayed on a screen (S14). In this case, since the group having the same number of weights as the group (GR2) is the group (GR1) and is composed of 12 weights, as shown in the drawing, the group (GR2) in the saved list of the left end number “3” is shown. “LOT- (B)” is displayed as a search result besides the column of the group (GR2) in the column of the group (GR1) of the row. Here, there is a thought that the operator only needs to recognize the number-of-mass information of each group in advance, but in general, an automatic winder is a machine having a large number of groups, and a plurality of machines are arranged in a factory. , There is a limit to the operator's grasp of all the numbers of weights in each group, and an error may occur. Therefore, as in the present invention, when the display is automatically performed by the machine controller 4, the setting status of the number of group weights can be known more accurately and easily.
[0031]
The search described above is performed by specifying a group having the number of weights corresponding to the number of weights of the restoration request lot, but is not limited thereto. In other words, when the operator designates an arbitrary group on the display screen, a restoration request (rewinding interruption) lot of the number of spindles corresponding to the number of spindles of this group is searched and displayed on the screen. The selection may be made as a lot.
[0032]
Thereafter, the cursor is moved by the operator, and it is determined whether or not an operation (restoration destination command) for selecting a restoration destination group has been performed (S15). If the restoration destination instruction has not been performed (S15, NO) ), And enters a standby state while re-executing S15. On the other hand, when the restoration destination command is issued to the group (GR2), for example (S15, YES), the restoration destination group (GR2) is determined, and an upward direction toward the display position of this group (GR2) is determined. Is displayed on the screen (S16).
[0033]
Thereafter, a confirmation window as to whether or not to assign the type information (lot data) to the restoration destination group is displayed in a pop-up, and the operator's judgment is requested. If the operator issues a command not to assign, the process shifts to S11 to return to the standby state for the restoration operation. On the other hand, when the operator issues a command for assignment, the operation information corresponding to the type information (lot data) is extracted from the lot suspension information file 73 in FIG. 1, and a restoration command signal including this operation information is output. The operation information is transmitted to the respective winding units 1 of the selected group (GR2), and the remaining winding is resumed with the voltage and the winding amount for the winding tension control solenoid 13 immediately before the interruption, which is the operation information. (S18).
Here, as in the present invention, when resuming the winding interrupted in the group (GR2), the search for an acceptable group is not necessarily performed in the group (GR2) immediately before the interruption. It is not necessary. For example, when the winding of the LOT- (D) type that has been interrupted and taken up by the group (GR2) is still continued or the winding is finished, the winding in the group (GR1) happens to end. This is because there is no problem in restoring the resumption of winding resumption of the LOT- (B) type interrupted in the group (GR2) even in the group (GR1). Also, after the winding of the LOT- (B) type in the group (GR2) is interrupted, if it is found from the search result of the receiving destination that the restoration can be received in the group (GR1), the LOT in the group (GR1) is possible. -(A) After stopping the winding of the product type, storing the operation information immediately before the interruption in the group (GR1), it is also possible to restart the LOT- (B) product type in the group (GR1). . By having such a search function, it is possible to more accurately grasp the receiving destination when selecting the restoration receiving destination at the time of resuming the winding process, and to provide flexibility in the selection.
[0034]
As described above, the automatic winder according to the present embodiment performs the winding process of unwinding the spun yarn Y from the yarn supply winding body B and winding the spun yarn Y into the winding package P as shown in FIGS. 1 and 7. A take-up unit 1; a take-up condition instructing means for starting take-up processing based on take-up conditions corresponding to the type; The information processing unit immediately before interruption (the information processing unit 75 immediately before interruption and an interrupt processing routine in FIG. 3) for acquiring and storing the tension and the winding amount) and the operation information of the interrupted winding unit are read out. The machine control device 4 is provided with a restoring control unit (restoring control unit 76, restoring process routine in FIG. 4) for restarting the winding process based on the control. This makes it possible to interrupt the winding unit in the middle of winding and interrupt the winding process for producing a package of another type. Furthermore, the winding process of the intermediate product when interrupted in the middle of rewinding can be easily restored to the state immediately before the interruption, and a package having a predetermined winding length can be obtained from the intermediate product.
In the present embodiment, the operation information is information on the amount of yarn wound on the winding package immediately before the suspension of winding. This makes it possible to interrupt the winding unit in the middle of winding and interrupt the winding process for producing a package of another type. Furthermore, the winding process of the intermediate product when interrupted in the middle of rewinding can be easily restored to the state immediately before the interruption, and a package having a predetermined winding length can be obtained from the intermediate product.
In the present embodiment, the winding unit includes a tension applying device that applies tension to the spun yarn being wound, and a control amount for the tension applying device is set in advance according to the winding amount. The operation information is a control amount to the tension applying device immediately before winding is interrupted. Thereby, when restoring to the state immediately before the interruption, the state of tension application can be accurately restored, and a package wound with an appropriate tension can be generated.
[0035]
In addition, a plurality of winding units 1 in the present embodiment are provided, and the winding conditions instructed by the winding condition instruction means are group units in which the plurality of winding units are grouped by an arbitrary number of units. The restoration control means is executable, and when resuming the winding process interrupted in a certain group unit, the restoration receiving searching means (recovery receiving unit) for searching for a group having a winding unit capable of accepting the resumption of the winding process The search unit 85 is provided with display means for displaying the search results (S13 and S14 in FIG. 4) and the search results. This makes it possible to perform the interrupt processing and the restoration processing in groups. Not only the voltage data for the winding tension control solenoid 13 and the winding amount but also other data may be stored, or any of these data may be stored.
[0036]
In the present embodiment, the case where the search processing is performed within one machine provided with the machine control device 4 is described. However, the present invention is not limited to this. A plurality of machines each including the machine control device 4 and the winding unit 1 are provided. The machine control devices 4 are connected to each other so as to be able to perform data communication, and the restoration reception provided in the production management device 62 and each machine control device 4 is performed. The search means may make it possible to search a group having a winding unit capable of accepting resumption of the winding process from all the units. In this case, the interrupt processing and the restoration processing can be performed in a wider range.
[0037]
Further, in the restoration processing according to the present embodiment, a group having the same number of units as the number of weights of the restoration request lot is set as an acceptable group, but is not limited thereto. That is, a group having the number of spindles equal to or greater than the number of groups whose winding processing has been interrupted may be selected as a resumable restoration receiving destination. In this case, it is preferable to display a pop-up display indicating whether the number of weights is larger or smaller than the number of units in the group.
[0038]
Further, the restoration processing may be performed in a divided manner. Specifically, a part of the total number of spindles in the group in which the winding process has been interrupted is restored in an arbitrary group, and the remaining spindles are continuously maintained in a state in which the operation information is stored in the lot interruption information file 73. It may be restored on the occasion of. In this case, the group corresponding to the remaining number of spindles can be restored as soon as it becomes available. The target of the winding unit to be restored may be selectable in units of weight. In this case, for example, since it is possible to sequentially select and restore a part of the weight in the group where the winding is interrupted in a state close to full with the weight in the group where the winding is interrupted, the winding package of the restored winding unit is used. As soon as the package is full, the remaining winding packages to be restored can be restored one by one. Thereby, the restoration processing of all the interrupted winding units can be completed as soon as possible. The above-mentioned restoration method is, for example, when there is no space in the group having the same or larger number of weights as the number of weights of the group for restarting the winding process, and even if there is an empty space, the number of units in the group that can be restored is insufficient. It is effective for
[0039]
