Description of Embodiment

The following describes in detail an exemplary embodiment of a yarn-winding machine to which a condition display device of the present disclosure is applied, with reference to the accompanying drawings. In each of the drawings, identical or equivalent portions are denoted by identical reference signs, and redundant explanations are omitted.
As illustrated in Fig. 1, a yarn-winding machine 1 includes a plurality of yarn winding units (yarn winding devices) 2, a plurality of unit control devices 3, a machine control device 4, and a monitoring-unit control device (a condition setting unit, a quality information generator) 5. The yarn-winding machine 1 is an automatic winder. Each yarn winding unit 2 winds a yarn drawn from a yarn winding body and forms a package. The yarn winding body is a yarn supplying bobbin 21a (see Fig. 2) or a yarn supplying package, for example. In the present embodiment, as a yarn winding body, the yarn supplying bobbin 21a is used. Each unit control device 3 is provided for each yarn winding unit 2 and controls the operation of the yarn winding unit 2 that is under control. The machine control device 4 performs communication with each unit control device 3 and controls the operation of the yarn winding unit 2. Each unit control device 3 may be provided for each of the multiple yarn winding units 2 and control the operation of the yarn winding units 2 that are under control.
The unit control device 3, the machine control device 4, and the monitoring-unit control device 5 are each configured as a computer device including, for example, a processor, a memory, a storage, and a communication device. In each control device, the processor executes predetermined software (a program) read into the memory or the like, and controls the reading and writing of data in the memory and the storage, and the communication among the control devices by the communication device, thereby implementing the functions of each control device which will be described later.
As illustrated in Fig. 2, the yarn winding unit 2 includes a yarn feeder 21, a tension applying unit 22, a tension detection unit 23, a yarn monitoring device (a yarn monitoring unit, a yarn-breakage detection unit) 24, a yarn joining unit 25, and a winding unit 26.
The yarn feeder 21 supplies a yarn. The yarn feeder 21 is made up of a bobbin supporting device or the like that supports the yarn supplying bobbin 21a. Onto the yarn supplying bobbin 21a, the yarn is wound. The tension applying unit 22 applies tension to the yarn that is drawn out from the yarn supplying bobbin 21a and is running toward the winding unit 26. The tension applying unit 22 is a gate-type tension applying device, a disk-type tension applying device, or the like. The tension detection unit 23 detects the tension produced on the yarn in winding the yarn. The unit control device 3 performs feedback control of a command value that is input to the tension applying unit 22 on the basis of the tension detected by the tension detection unit 23 such that the tension applied to the yarn by the tension applying unit 22 becomes a target value.
The yarn monitoring device 24 monitors a state of the yarn that runs toward the winding unit 26 from the yarn feeder 21, and detects a yarn defect. The yarn monitoring device 24 includes a detector 24a and a yarn monitoring controller 24b. The detector 24a detects a state of the yarn. Specifically, the detector 24a is an optical sensor that detects temporal changes in the thickness of the yarn by the changes in the amount of receiving light by irradiating the yarn with light, a capacitance sensor that detects the temporal changes in the amount of fibers of the yarn by the changes in capacitance by passing the yarn through an electric field, or the like. The detector 24a outputs to the yarn monitoring controller 24b a waveform signal indicative of the temporal changes in the thickness of the yarn or the amount of fibers.
The yarn monitoring controller 24b determines the presence of a yarn defect on the basis of the input waveform signal. If there is a yarn defect, the yarn monitoring controller 24b activates a cutter and cuts the yarn. The cutter may be provided in the yarn monitoring device 24, or may be provided in an appropriate place in the yarn winding unit 2 other than the yarn monitoring device 24.
In more detail, the yarn monitoring controller 24b determines the presence of a yarn defect on the basis of the input waveform signal (a detection result by the detector 24a) and a yarn-defect determination condition that is set in advance. In the present embodiment, the yarn-defect determination condition is set by the monitoring-unit control device 5. The yarn-defect determination condition is a condition that determines under what kind of state the yarn is determined as a yarn defect. The yarn-defect determination condition includes various setting items (setting values) for determining the presence of a yarn defect. That is, the yarn-defect determination condition is a lump (lot) of various setting items for performing the determination of the presence of a yarn defect. For example, in the yarn-defect determination condition, the length, the thickness, or the fiber amount of a yarn defect that is a subject to be removed may be included. The yarn-defect determination condition is changed according to the quality, specifications, and the like that are desired for the yarn, for example.
The yarn monitoring controller 24b outputs a yarn-defect detection signal to the unit control device 3, when a yarn defect is detected. The yarn monitoring controller 24b further outputs a detection result by the detector 24a to the monitoring-unit control device 5. The yarn monitoring device 24 can also detect the speed of yarn that runs toward the winding unit 26 from the yarn feeder 21, a foreign object that is included in the yarn, a yarn breakage, and the like.
The monitoring-unit control device 5 is communicably connected to a plurality of yarn monitoring controllers 24b, and collectively manages the yarn monitoring controllers 24b. The monitoring-unit control device 5 transmits the yarn-defect determination condition to each yarn monitoring controller 24b, and receives the detection result by the detector 24a from each yarn monitoring controller 24b. That is, the monitoring-unit control device 5 sets the yarn-defect determination condition to the yarn monitoring controller 24b. The monitoring-unit control device 5 outputs the yarn-defect determination condition to the machine control device 4. The monitoring unit device 5 further generates quality information indicative of the quality of yarn on the basis of the detection result by the detector 24a, and outputs the quality information to the machine control device 4.
The yarn joining unit 25 performs yarn joining operation that joins together the yarn on the yarn feeder 21 side and the yarn on the winding unit 26 side, when the yarn is cut in order to remove a yarn defect detected by the yarn monitoring device 24 or when a yarn breakage is detected by the yarn monitoring device 24. The yarn joining unit 25 is made up of a first yarn catching device, a second yarn catching device, a yarn joining device, and the like. The first yarn catching device catches the yarn on the yarn feeder 21 side by suction and guides it to the yarn joining device. The second yarn catching device catches the yarn on the winding unit 26 side by suction and guides it to the yarn joining device. The yarn joining device is a splicer that uses compressed air, a piecer that uses a seed yarn, or a knotter that mechanically joins yarn, and joins the guided yarns.
The winding unit 26 winds the yarn onto a bobbin and forms a package 26a. The winding unit 26 is made up of a cradle arm, a winding drum, and the like. The cradle arm rotatively supports the package 26a. The winding drum rotates the package 26a in contact with the surface of the package 26a that is supported by the cradle arm. On the winding drum, a traverse groove is formed, and by the traverse groove, the yarn is traversed at a predetermined width with respect to the rotating package 26a. It may be configured such that a motor directly drives the package 26a to rotate, or may be configured such that the winding drum has no traverse groove and a separate traverse device (for example, a traverse arm) is provided.
As illustrated in Fig. 3, the machine control device 4 includes a touch panel 41, a winding controller 42, a winding-condition acquisition unit 43, a determination-condition acquisition unit 44, an operation-information acquisition unit 45, a display controller 46, an association unit 47, and a storage unit 48. The touch panel 41, the winding-condition acquisition unit 43, the determination-condition acquisition unit 44, the operation-information acquisition unit 45, the display controller 46, the association unit 47, and the storage unit 48 function as a condition display device 40 that displays information concerning the winding condition and information concerning the yarn-defect determination condition. That is, in the present embodiment, the condition display device 40 is incorporated in the machine control device 4 that controls the yarn winding units 2.
The touch panel 41 displays various information presented to an operator and receives the input of various information by the operator. In the present embodiment, the touch panel 41 can display the information concerning the winding condition and the information concerning the yarn-defect determination condition. The touch panel 41 can further receive the input of the winding condition and the input of the yarn-defect determination condition by the operator. The operator can set the winding condition and the yarn-defect determination condition by inputting the winding condition and the yarn-defect determination condition to the touch panel 41. Thus, the touch panel 41 functions as a display unit and also functions as a winding-condition input unit and a determination-condition input unit.
The winding controller 42 operates the various units in the yarn winding unit 2 on the basis of the winding condition set in advance by the operator and winds the yarn. The winding condition is a condition to determine under what kind of state the yarn is wound. The winding condition includes various setting items (setting values) for winding the yarn. That is, the winding condition is a lump (lot) of various setting items for winding the yarn. For example, in the winding condition, the strength of tension applied to the yarn by the tension applying unit 22, and the winding speed of the yarn in the winding unit 26 may be included. The winding condition is changed according to the quality, specifications, and the like that are desired for the yarn, for example.
The winding-condition acquisition unit 43 acquires the winding condition with which the yarn winding unit 2 winds the yarn and forms the package 26a. Specifically, the winding-condition acquisition unit 43 can acquire from the winding controller 42 the winding condition set in the winding controller 42, for example. The winding-condition acquisition unit 43 may further acquire the winding condition that the operator input to the touch panel 41. The fact that the operator inputs the winding condition to the touch panel 41 also includes selecting the lump (lot) of various setting items.
The determination-condition acquisition unit 44 acquires the yarn-defect determination condition with which the yarn monitoring controller 24b of the yarn monitoring device 24 determines the presence of a yarn defect. Specifically, the determination-condition acquisition unit 44 can acquire from the monitoring-unit control device 5 the yarn-defect determination condition set to the yarn monitoring controller 24b, by performing communication with the monitoring-unit control device 5, for example. The determination-condition acquisition unit 44 may acquire the yarn-defect determination condition that the operator input to the touch panel 41. For example, the determination-condition acquisition unit 44 may acquire the yarn-defect determination condition input to the touch panel 41 (or a dedicated touch panel provided for the yarn monitoring device 24 separately from the touch panel 41), when the operator sets the yarn-defect determination condition to the yarn monitoring controller 24b. The fact that the operator inputs the yarn-defect determination condition to the touch panel 41 also includes selecting the lump (lot) of various setting items.
The determination-condition acquisition unit 44 may acquire quality information about the yarn from the monitoring-unit control device 5 and, based on the acquired quality information, grasp the yarn-defect determination condition. Specifically, the determination-condition acquisition unit 44 estimates a yarn defect that is a subject to be removed in order to achieve the yarn quality indicated in the acquired quality information and, based on the estimated yarn defect that is the subject to be removed, grasps the yarn-defect determination condition. The quality information that the determination-condition acquisition unit 44 acquires from the monitoring-unit control device 5 may be grade information indicative of a grade of yarn quality. In this case, the determination-condition acquisition unit 44 may estimate a yarn defect that is a subject to be removed in order to achieve the grade of yarn indicated in the grade information and, based on the estimated yarn defect that is the subject to be removed, grasp the yarn-defect determination condition.
The determination-condition acquisition unit 44 acquires at least a name given to the yarn-defect determination condition, as the yarn-defect determination condition. The name given to the yarn-defect determination condition may be the name of the yarn-defect determination condition itself, or may be identification information such as an identification number for identifying the name of the yarn-defect determination condition. Alternatively, the determination-condition acquisition unit 44 may acquire a setting value set as the yarn-defect determination condition, together with the name given to the yarn-defect determination condition, as the yarn-defect determination condition.
The operation-information acquisition unit 45 acquires an operation status of the yarn-windingmachine 1. The operation status includes information such as the number of times of yarn breakage (the number of times of yarn joining), and an actual winding speed of the yarn, for example. The operation-information acquisition unit 45 acquires the operation information from the yarn monitoring device 24, the winding controller 42, and the like.
The display controller 46 causes the touch panel 41 to display the information concerning the winding condition acquired in the winding-condition acquisition unit 43, and the information concerning the yarn-defect determination condition acquired in the determination-condition acquisition unit 44. In more detail, the display controller 46 causes the touch panel 41 to display, as the information concerning the winding condition and the yarn-defect determination condition to be displayed on the touch panel 41, the information concerning the winding condition acquired in the winding-condition acquisition unit 43, and the information concerning the yarn-defect determination condition with which the yarn monitoring controller 24b determines the presence of a yarn defect for the yarn that is wound under the winding condition acquired in the winding-condition acquisition unit 43. As just described, the display controller 46 causes the touch panel 41 to display the information concerning the winding condition, and the information concerning the yarn-defect determination condition corresponding to this winding condition.
The display controller 46 may cause the touch panel 41 to display the information concerning the yarn-defect determination condition together with the information concerning the winding condition, such that the information concerning the winding condition and the yarn-defect determination condition is simultaneously displayed on the touch panel 41. The display controller 46 may cause, based on a switching operation of the operator, the touch panel 41 to display in a switchable fashion the information concerning the winding condition and the information concerning the yarn-defect determination condition corresponding to this winding condition.
The display controller 46 can cause the touch panel 41 to display the information concerning the winding condition and the yarn-defect determination condition at any timing before starting the winding of the yarn in the yarn winding unit 2, during the winding, and after ending the winding, as long as after acquiring the winding condition and the yarn-defect determination condition by the respective winding-condition acquisition unit 43 and the determination-condition acquisition unit 44.
The display controller 46 may, in displaying the information concerning the winding condition and the yarn-defect determination condition on the touch panel 41, cause the touch panel 41 to display the yarn quality information acquired from the monitoring-unit control device 5 in association with the winding condition and the yarn-defect determination condition. This yarn quality information is the yarn quality information when the winding and the determination of the presence of a yarn defect are performed under the winding condition and the yarn-defect determination condition displayed on the touch panel 41.
The display controller 46 may, in displaying the information concerning the winding condition and the yarn-defect determination condition on the touch panel 41, cause the touch panel 41 to display the operation status acquired in the operation-information acquisition unit 45 in association with the winding condition and the yarn-defect determination condition. The display controller 46 may, in displaying the information concerning the winding condition and the yarn-defect determination condition on the touch panel 41, cause the touch panel 41 to display the number of times of yarn breakage detected in the yarn monitoring device 24. This number of times of yarn breakage may be the number of times of yarn breakage from the winding start of the package 26a when the yarn winding unit 2 is being operated under the winding condition and the yarn-defect determination condition displayed on the touch panel 41, for example.
The association unit 47 associates the winding condition acquired in the winding-condition acquisition unit 43 and the yarn-defect determination condition acquired in the determination-condition acquisition unit 44 with each other, and causes the storage unit 48 to store therein the associated conditions. In more detail, the association unit 47 associates with each other the winding condition acquired in the winding-condition acquisition unit 43, and the yarn-defect determination condition with which the yarn monitoring controller 24b determines the presence of a yarn defect for the yarn that is wound under the acquired winding condition. The association unit 47 then causes the storage unit 48 to store therein the associated winding condition and the yarn-defect determination condition.
The association unit 47 may acquire quality information about the yarn from the monitoring-unit control device 5. In this case, the association unit 47 may also associate the yarn quality information, for which the winding and the determination of the presence of a yarn defect are performed under these winding condition and the yarn-defect determination condition, with those winding condition and the yarn-defect determination condition, in addition to the winding condition and the yarn-defect determination condition. Then, the association unit 47 causes the storage unit 48 to store therein the associated winding condition, the yarn-defect determination condition, and the quality information.
The association unit 47 may also cause the storage unit 48 to store therein the number of times of yarn breakage detected in the yarn monitoring device 24, and the operation information acquired in the operation-information acquisition unit 45, in association with the winding condition and the yarn-defect determination condition, as with the yarn quality information.
The display controller 46 can cause the touch panel 41 to display the information concerning the winding condition and the yarn-defect determination condition on the basis of the information stored in the association unit 47. For example, a state in which the yarn-defect determination condition is not set in the yarn monitoring controller 24b is assumed. Then, it is assumed that the operator input the winding condition via the touch panel 41 and the winding-condition acquisition unit 43 acquired the winding condition. In this case, the display controller 46 may extract the yarn-defect determination condition associated with the winding condition acquired in the winding-condition acquisition unit 43 from the storage unit 48, and cause the touch panel 41 to display the information concerning the extracted yarn-defect determination condition, and the information concerning the winding condition acquired in the winding-condition acquisition unit 43. At that time, the display controller 46 may cause the touch panel 41 to also display the yarn quality information associated with the winding condition and the yarn-defect determination condition displayed on the touch panel 41, in association with the winding condition and the yarn-defect determination condition. The display controller 46 may cause the touch panel 41 to also display the number of times of yarn breakage and the yarn quality information, in association with the winding condition and the yarn-defect determination condition, as with the yarn quality information.
As a result, the operator can, by inputting the winding condition, grasp the information concerning the yarn-defect determination condition, the yarn quality information, and the like corresponding to the input winding condition. That is, the operator can grasp the yarn-defect determination condition that was used by the yarn monitoring controller 24b in the past in determining the presence of a yarn defect for the yarn that is wound under the input winding condition, and grasp the yarn quality information, the number of times of yarn breakage, and the operation status under such a condition.
The display controller 46 may cause the touch panel 41 to display, as the information concerning the winding condition, the name (for example, a lot name) of the winding condition set (given) for each winding condition. Similarly, the display controller 46 may cause the touch panel 41 to display, as the information concerning the yarn-defect determination condition, the name (for example, a lot name) of the yarn-defect determination condition set (given) for each yarn-defect determination condition. The operator can grasp the winding condition and the yarn-defect determination condition, by checking the name of the winding condition and the name of the yarn-defect determination condition displayed on the touch panel 41.
The display controller 46 may cause the touch panel 41 to display, as the information concerning the winding condition, the setting values of the setting items of the winding condition set for each winding condition . Similarly, the display controller 46 may cause the touch panel 41 to display, as the information concerning the yarn-defect determination condition, the setting values of the setting items of the yarn-defect determination condition set for each yarn-defect determination condition. The display controller 46 may cause the touch panel 41 to display, as the information concerning the winding condition, the setting values of the setting items of the winding condition together with the name of the winding condition. Similarly, the display controller 46 may cause the touch panel 41 to display, as the information concerning the yarn-defect determination condition, the setting values of the setting items of the yarn-defect determination condition together with the name of the yarn-defect determination condition.
The association unit 47 may, in associating the winding condition with the yarn-defect determination condition, associate with each other the name of the winding condition and the name of the yarn-defect determination condition, but not the various setting items. The association unit 47 may cause the storage unit 48 to store therein the associated name of the winding condition and the name of the yarn-defect determination condition.
Fig. 4 illustrates an example of a display screen displayed on the touch panel 41. In the example illustrated in Fig. 4, a plurality of yarn winding units 2 are divided into "group 1" and "group 2", and the winding condition and the yarn-defect determination condition are displayed for each group. For example, as for the group 1, displayed are the name of the winding condition "winding lot setting 1" and the setting values of various setting items (winding condition 1, winding condition 2, ..., winding condition X) in this winding condition. In addition, displayed is the name of the yarn-defect determination condition "determination lot setting A" corresponding to this winding condition.
The display screen example illustrated in Fig. 4 may be a display screen example at the time the operator input the winding condition, the display controller 46 extracted from the storage unit 48 the yarn-defect determination condition corresponding to the input winding condition, and then the display controller 46 caused the touch panel 41 to display the input information concerning the winding condition and the information concerning the extracted yarn-defect determination condition, for example. The display screen example illustrated in Fig. 4 may be a display screen example at the time the winding-condition acquisition unit 43 and the determination-condition acquisition unit 44 acquired the respective winding condition and the yarn-defect determination condition set to the current yarn winding unit 2 and the display controller 46 caused the touch panel 41 to display the acquired information concerning the winding condition and the information concerning the yarn-defect determination condition, for example.
As just described, in the condition display device 40, the winding condition is acquired by the winding-condition acquisition unit 43 and the yarn-defect determination condition is acquired by the determination-condition acquisition unit 44. On the touch panel 41, displayed are the information concerning the winding condition acquired in the winding-condition acquisition unit 43, and the information concerning the yarn-defect determination condition with which the yarn monitoring controller 24b determines the presence of a yarn defect for the yarn that is wound under the winding condition acquired in the winding-condition acquisition unit 43. As just described, the display controller 40 can display both of the information concerning the winding condition, and the information concerning the yarn-defect determination condition corresponding to this winding condition. Accordingly, the operator can grasp under what kind of winding condition the yarn is wound, and under what kind of yarn-defect determination condition the presence of a yarn defect for the yarn is determined.
The determination-condition acquisition unit 44 can acquire from the monitoring-unit control device 5 the yarn-defect determination condition set to the yarn monitoring controller 24b. In this case, the determination-condition acquisition unit 44 can easily acquire the yarn-defect determination condition from the monitoring-unit control device 5.
The determination-condition acquisition unit 44 can acquire the yarn quality information from the monitoring-unit control device 5 and, based on the acquired quality information, grasp the yarn-defect determination condition. In this case, even when it is not possible to acquire the yarn-defect determination condition directly, the determination-condition acquisition unit 44 can acquire the yarn-defect determination condition on the basis of the quality information.
The determination-condition acquisition unit 44 may acquire the yarn-defect determination condition on the basis of the input to the touch panel 41 by the operator. In this case, even when it is not possible to perform communication with the monitoring-unit control device 5, the determination-condition acquisition unit 44 can acquire the yarn-defect determination condition on the basis of the input of the operator. Then, the display controller 46 can cause the touch panel 41 to display the information concerning the winding condition acquired in the winding-condition acquisition unit 43, and the information concerning the yarn-defect determination condition acquired in the determination-condition acquisition unit 44 on the basis of the input of the operator.
The winding-condition acquisition unit 43 can acquire from the winding controller 42 the winding condition set in the winding controller 42. In this case, the winding-condition acquisition unit 43 can easily acquire the winding condition from the winding controller 42.
The association unit 47 associates with each other the winding condition acquired in the winding-condition acquisition unit 43, and the yarn-defect determination condition with which the yarn monitoring controller 24b determines the presence of a yarn defect for the yarn that is wound under the winding condition acquired in the winding-condition acquisition unit 43. The association unit 47 can cause the storage unit 48 to store therein the associated winding condition and the yarn-defect determination condition. In this case, the storage unit 48 can store therein these conditions in a state where the winding condition and the yarn-defect determination condition corresponding to this winding condition are associated with each other.
When the winding-condition acquisition unit 43 acquired the winding condition on the basis of the input to the touch panel 41 of the operator, the display controller 46 extracts from the storage unit 48 the yarn-defect determination condition associated with the acquired winding condition. Then, the display controller 46 causes the touch panel 41 to display the information concerning the extracted yarn-defect determination condition, and the information concerning the winding condition acquired in the winding-condition acquisition unit 43. In this case, the operator can, by inputting the winding condition, grasp the yarn-defect determination condition associated with the input winding condition. For example, the operator may, after inputting the winding condition, check the yarn-defect determination condition displayed on the touch panel 41 and set the yarn-defect determination condition for the yarn monitoring controller 24b. As a result, the operator can grasp the yarn-defect determination condition that was set in the past and the like corresponding to the input winding condition, for example.
When the determination-condition acquisition unit 44 acquired the yarn-defect determination condition on the basis of the input to the touch panel 41 of the operator, the display controller 46 extracts from the storage unit 48 the winding condition associated with the acquired yarn-defect determination condition. Then, the display controller 46 may cause the touch panel 41 to display the information concerning the extracted winding condition, and the information concerning the yarn-defect determination condition acquired in the determination-condition acquisition unit 44.
The display controller 46 causes the touch panel 41 to display the yarn quality information in association with the winding condition and the yarn-defect determination condition. In this case, the operator can visually recognize the winding condition, the yarn-defect determination condition, and the quality information in a comparable manner. Then, the operator can, when it is found that the yarn quality is not satisfactory from the quality information, check the winding condition and the yarn-defect determination condition corresponding thereto and consider a change and the like in each condition, for example.
The display controller 46 causes the touch panel 41 to display, as the information concerning the yarn-defect determination condition, the name of the yarn-defect determination condition. In this case, the operator can grasp the yarn-defect determination condition, by visually recognizing the name displayed on the touch panel 41.
The display controller 46 causes the touch panel 41 to display, as the information concerning the yarn-defect determination condition, the setting values set as the yarn-defect determination condition together with the name of the yarn-defect determination condition. As a result, the operator can grasp the detail of the yarn-defect determination condition, by visually recognizing the name and the setting values displayed on the touch panel 41.
The display controller 46 causes the touch panel 41 to display the operation information acquired by the operation-information acquisition unit 45, together with the information concerning the yarn-defect determination condition. In this case, the operator can visually recognize the winding condition, the yarn-defect determination condition, and the operation status in a comparable manner. Then, the operator can grasp the influence of each condition to the operation status and consider a change and the like in each condition. For example, when the number of times of yarn joining (the number of times of yarn breakage) is large, the operator can check whether there is a problem in the winding condition or whether the yarn-defect determination condition is too strict, and consider a change and the like in each condition.
The display controller 46 causes the touch panel 41 to display the number of times of yarn breakage detected by the yarn monitoring device 24, together with the information concerning the yarn-defect determination condition and the like. In this case, the operator can check the number of times of yarn breakage and consider a change and the like in each condition.
As in the foregoing, the embodiment of the present disclosure has been described. The disclosure, however, is not limited to the above-described embodiment. For example, the condition display device 40 is not limited to being provided in the machine control device 4. The condition display device 40 may be provided in the unit control device 3, or may be provided independently of the unit control device 3, the machine control device 4, and the like. The winding-condition input unit to which the operator inputs the winding condition and the determination-condition input unit to which the yarn-defect determination condition is input may be configured by an operation button and the like separately from the touch panel 41. The touch panel may be provided individually for the machine control device 4 and the monitoring-unit control device 5.
The yarn monitoring device 24 may be not provided with the yarn monitoring controller 24b that determines the presence of a yarn defect. In this case, the unit control device 3, the machine control device 4, or the monitoring-unit control device 5 may determine the presence of a yarn defect on the basis of the detection result by the detector 24a and the yarn-defect determination condition, for example. The yarn-winding machine 1 may be not provided with the monitoring-unit control device 5. In this case, the yarn monitoring controller 24b performs communication directly with the unit control device 3 or the machine control device 4, or performs communication with the machine control device 4 via the unit control device 3, and the yarn monitoring controller 24b outputs the detection result by the detector 24a or the yarn-defect determination condition to the unit control device 3 or the machine control device 4. As a result, the determination-condition acquisition unit 44 can acquire the yarn-defect determination condition from the yarn monitoring device 24.
The winding condition and the yarn-defect determination condition stored in the storage unit 48 are not limited to being available to the machine control device 4, and may be available to the yarn monitoring device 24 also.
The winding condition and the yarn-defect determination condition are managed by controllers different from each other (for example, controllers provided away from each other, or controllers configured on separate substrates; in the above-described embodiment, the winding controller 42 and the monitoring-unit control device 5, or the winding controller 42 and the yarn monitoring controller 24b) . That is, the winding condition and the yarn-defect determination condition are stored in the storage units that the respective controllers include, for example. In the above-described embodiment, as for the winding condition, the storage unit 48 that stores therein the winding condition and the yarn-defect determination condition in association with each other may also have a function of storing the winding condition. The condition display device 40 of the present embodiment can acquire the winding condition and the yarn-defect determination condition from the respective controllers (read out from the respective storage units), cause the storage unit 48 to store therein both of the acquired conditions, and cause the touch panel 41 to display the conditions.
