Description

  The present invention relates to a textile machine including a plurality of yarn processing units. Specifically, the present invention relates to a configuration for displaying the operating state of the yarn processing unit.

A general textile machine has a plurality of yarn processing units such as a spinning machine having a plurality of spinning units and an automatic winder having a plurality of winder units. This type of textile machine generally includes a centralized management device (machine control device) that collectively manages information related to each yarn processing unit. The following Patent Documents 1 to 3 disclose a textile machine including a centralized management device that centrally manages a plurality of yarn processing units. In such a centralized management apparatus, various types of information such as the operation efficiency of each yarn processing unit and the occurrence state of an abnormality (error) can be displayed on the monitor.

On the other hand, Patent Document 4 discloses a winder unit in which a panel is provided on the front surface of each unit, and each panel displays a plurality of single images that schematically depict the cause of the abnormality. The winder unit disclosed in Patent Document 3 is configured to notify an abnormality occurrence location by causing a single image corresponding to the abnormality to emit light when the abnormality occurs.
German Patent Application No. 102006045237

  By the way, in a textile machine having a configuration including a centralized management device as in Patent Documents 1 to 3, by performing a predetermined operation in the centralized management device, a yarn processing unit that matches a desired condition can be extracted. It is also conceivable to configure so as to be able to. In this case, the operator performs appropriate operations, for example, extracts (lists) units with lower operating efficiency than the average of the entire machine base and displays them on the monitor, and maintenance work is required based on this display. It is possible to work by moving to the installation location of the yarn processing unit.

  However, in such a configuration, the operator must frequently reciprocate between the central management device and the yarn processing unit in order to confirm the display on the monitor. For this reason, the efficiency at the time of work was bad, and it was a burden for the operator.

  Further, in the above configuration, an inefficient unit or the like is displayed on the monitor when the operator performs an appropriate operation in the centralized management apparatus. For this reason, even if the efficiency of a certain yarn processing unit is reduced during operation of the apparatus, the operation efficiency of the yarn processing unit is reduced until the operator confirms the monitor by performing a predetermined operation with the machine base control device. I can't figure it out. Accordingly, it has been impossible to grasp the yarn processing unit whose efficiency has been lowered at an early stage and perform an appropriate treatment.

  On the other hand, since Patent Document 4 is configured to display the cause of an abnormality on the front panel, when the abnormality occurs, in order to obtain information on the abnormality, the central management apparatus does not have to check the monitor on the spot. Abnormalities occurring in the yarn processing unit can be grasped. However, since the configuration of Patent Document 4 does not display information related to the yarn processing unit except when an abnormality occurs, it has not been possible to grasp the state of the operating yarn processing unit.

  This invention is made in view of the above situation, The objective is to provide the textile machine which can grasp | ascertain the driving | running state of a yarn processing unit easily.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to the viewpoint of this invention, the textile machine of the following structures is provided. That is, this textile machine includes a plurality of yarn processing units. Each of the yarn processing units includes a level display unit that displays which operation level the operation state of the yarn processing unit corresponds to among a plurality of operation levels.

  Thus, the operator can easily grasp the state of the yarn processing unit by checking the operation level of the yarn processing unit. In addition, since each yarn processing unit includes a level display unit, the operator can check the operation level on the spot. Therefore, the operator can easily grasp the yarn processing unit that needs to be treated, and can immediately apply the treatment to the yarn processing unit on the spot.

  In the textile machine, it is preferable that the operation level is divided so that a reference operation state as a reference is in the center.

  Thereby, it is possible to easily grasp whether the operation state of the yarn processing unit is at a higher or lower operation level than the reference operation state.

  In the textile machine, the reference operating state is preferably an average value of operating states of a plurality of yarn processing units provided in the textile machine.

  Thereby, it is possible to easily grasp which direction the yarn processing unit is operating in a state shifted from the average value. In addition, since the average value is used for the center level of the level display, it can be easily compared with the operating states of other yarn processing units.

  In the textile machine, the reference operation state may be a predetermined set value.

  As a result, it is possible to easily grasp which direction the yarn processing unit is operating in a state shifted from the set value.

  The textile machine is preferably configured as follows. That is, the operation level of the yarn processing unit is obtained based on operation data obtained by detecting the operation state of the yarn processing unit, and the yarn processing unit can detect a plurality of types of operation data. The textile machine can switch which of the plurality of types of operation data is used to determine the operation level.

  That is, by making the content displayed on the level display section switchable, it is possible to display different types of information related to the yarn processing unit by one level display section.

  In the textile machine, the operation level relates to at least one of the operation efficiency of the yarn processing unit, the thickness of the yarn of the yarn processing unit, and the yarn splicing error rate of the yarn processing unit. It is preferable.

  That is, since the operation data related to the above-described operation state is frequently referred to by the operator, it is particularly preferable to be able to display it on the level display unit of the present invention.

  In the textile machine, it is preferable that each of the yarn processing units includes a tendency display unit that displays whether the operation state of the yarn processing unit is in an upward trend or a downward trend.

  Thereby, since the recent tendency of the operating state of the yarn processing unit can be easily grasped, the operator can take an appropriate measure for each yarn processing unit.

  Next, a spinning machine (spinning machine) as a textile machine according to an embodiment of the present invention will be described with reference to the drawings. In the present specification, “upstream” and “downstream” mean upstream and downstream in the traveling direction of the yarn during spinning.

You can also Further, the operator can change the setting for a specific spinning unit 2 or change the settings of all the spinning units 2 collectively by performing an appropriate operation using the input key 62. (This setting change is performed by transmitting setting data from the machine base control device 60 to the unit control unit 73 described later). In addition to the spinning unit 2, the machine base control device 60 is configured to be able to control and manage, for example, the yarn splicing cart 3 and an automatic doffing device (not shown).

  As shown in FIG. 2, the spinning machine 1 includes a plurality of unit control units 73 for controlling the spinning units 2. In the present embodiment, the unit controller 73 is configured to control and manage four spinning units 2, and is detected by a control signal from the machine base control device 60 and various sensors included in each spinning unit 2. Each spinning unit 2 is controlled based on the signal and the like. Further, the unit controller 73 is configured to be able to transmit information regarding each spinning unit 2 to the machine control device 60.

  Each spinning unit 2 is for forming a package 45 from a sliver 15 as shown in FIG. 1, and in order from upstream to downstream, a draft device 7, a spinning device 9, a yarn feeding device 11, and The yarn slack eliminating device 12 and the winding device 13 are provided as main components. The draft device 7 is provided in the vicinity of the upper end of the casing 6 of the spinning machine 1, and the fiber bundle 8 sent from the draft device 7 is configured to be spun by the spinning device 9. The spun yarn 10 discharged from the spinning device 9 is fed by the yarn feeding device 11, passes through a yarn clearer 52 described later, and then wound by the winding device 13 to form a package 45. Each spinning unit 2 includes an operation panel 80 at an appropriate position on the front side of the apparatus.

  The yarn splicing cart 3 is configured to be able to travel in the direction in which the spinning units 2 are arranged. At the time of yarn cutting (described later), the yarn travels to the position of the spinning unit 2 that requires splicing, and the upper yarn on the spinning device 9 side and the lower yarn on the winding device 13 side can be spliced. It is configured as follows.

  Next, the detailed configuration of each spinning unit 2 will be described with reference to FIG. FIG. 3 is a longitudinal sectional view of the spinning machine 1.

  The draft device 7 is for drawing the sliver 15 into the fiber bundle 8. As shown in FIG. 3, the draft device 7 includes four rollers: a back roller 16, a third roller 17, a middle roller 19 on which an apron belt 18 is mounted, and a front roller 20.

  Next, the configuration of the spinning unit will be described. The spinning unit mainly includes a spinning device 9, a yarn feeding device 11, and a yarn slack eliminating device 12.

  Although a detailed configuration of the spinning device 9 is not illustrated, in the present embodiment, a pneumatic type that generates a spun yarn 10 by twisting the fiber bundle 8 using a swirling airflow is adopted.

  The yarn feeding device 11 includes a delivery roller 39 supported by the casing 6 of the spinning machine 1 and a nip roller 40 provided in contact with the delivery roller 39. With this configuration, the spun yarn 10 discharged from the spinning device 9 is sandwiched between the delivery roller 39 and the nip roller 40, and the delivery roller 39 is rotated by an electric motor (not shown) to take up the spun yarn 10. It is sent to the device 13 side.

  A yarn clearer 52 is provided on the front side of the casing 6 of the spinning machine 1 and slightly downstream of the yarn feeding device 11. The spun yarn 10 spun by the spinning device 9 is configured to pass through the yarn clearer 52 before being wound by the winding device 13. The yarn clearer 52 is configured to monitor the thickness and speed of the traveling spun yarn 10 and to transmit a yarn defect detection signal to the unit controller 73 when a yarn defect of the spun yarn 10 is detected. Further, a cutter 57 for cutting the spun yarn 10 when a yarn defect is detected is provided in the vicinity of the yarn clearer 52.

  The yarn slack eliminating device 12 is configured to remove slack of the spun yarn 10 between the spinning device 9 and the winding device 13 (between the spinning device 9 and a splicer 43 described later) and to apply an appropriate tension. Has been. The yarn slack eliminating device 12 mainly includes a slack eliminating roller 21 and a yarn hooking member 22. Although the detailed description of the yarn slack eliminating device 12 is omitted, the spun yarn 10 is wound around the outer periphery of the slack eliminating roller 21 and stored, and the stored yarn functions as a buffer, so that the tension of the spun yarn 10 is increased. The yarn is prevented from slackening by absorbing the fluctuation of the yarn.

  Next, the winding device 13 will be described. The winding device 13 includes a cradle arm 71 supported so as to be swingable around a support shaft 70, and the cradle arm 71 can rotatably support a bobbin around which the spun yarn 10 is wound. The winding device 13 includes a winding drum 72 and a traverse device 75.

  The winding drum 72 is configured to be able to be driven in contact with the outer peripheral surface of the package 45 formed by winding the bobbin and the spun yarn 10 thereon. The traverse device 75 includes a traverse guide 76 that can be engaged with the spun yarn 10. The traverse guide 76 is fixed to a traverse rod 77 arranged horizontally across the plurality of spinning units 2. In this configuration, the winding drum 72 is driven by an electric motor (not shown) while the traverse rod 77 is reciprocated by a driving means (not shown), thereby rotating the package 45 in contact with the winding drum 72 and spinning the yarn 10. Can be wound while traversing.

  Next, the yarn joining cart 3 will be described. As shown in FIGS. 1 and 3, the yarn joining cart 3 includes a splicer (yarn joining device) 43, a suction pipe 44, a suction mouth 46, and a lower yarn detection sensor 58. The yarn splicing carriage 3 is provided so as to run on a rail 41 provided in the casing 6 of the spinning machine 1. With this configuration, when yarn breakage or yarn cut occurs in a spinning unit 2, the yarn splicing carriage 3 travels to the spinning unit 2 and stops to perform a yarn splicing operation.

  Hereinafter, the yarn joining operation by the yarn joining cart 3 will be specifically described. As described above, when the yarn clearer 52 detects a yarn defect of the spun yarn 10, a yarn defect detection signal is transmitted to the unit controller 73. Upon receipt of the yarn defect detection signal, the unit control unit 73 immediately cuts the yarn with the cutter 57, and further stops the draft device 7, the spinning device 9, the winding device 13, and the like, Drive to the front of unit 2.

  Subsequently, the unit control unit 73 drives the draft device 7 and the spinning device 9 of the spinning unit 2 again and starts capturing the yarn end by the suction pipe 44 and the suction mouth 46 provided in the yarn splicing cart 3. . The suction pipe 44 sucks the yarn end of the upper yarn discharged from the spinning device 9 and guides it to the splicer 43 while rotating in the vertical direction around the axis. Before and after this, the suction mouse 46 sucks and captures the yarn end of the lower thread from the package 45 rotatably supported by the winding device 13 while rotating in the vertical direction about the axis. To the splicer 43.

  At this time, if the yarn clearer 52 does not detect the yarn despite the completion of the upper yarn guiding operation by the suction pipe 44, it is determined that the upper yarn has been caught, and the upper yarn catching operation is performed in a predetermined manner. Retry a number of times. If the lower thread detecting sensor 58 does not detect the thread even though the lower thread guiding operation by the suction mouse 46 is finished, it is determined that the lower thread has been captured, and the lower thread capturing operation is performed. Retry a predetermined number of times. If the yarn end is not successfully captured even after a predetermined number of retries, the unit controller 73 determines that a yarn splicing error has occurred.

  When the upper yarn and the lower yarn are guided to the splicer 43, the splicer 43 performs the splicing of the guided yarn ends. Although a detailed configuration of the splicer 43 will not be described, for example, the yarn splicing may be performed by a method of twisting yarn ends with a fluid such as a compressed air flow. When the yarn splicing is completed, the winding by the winding device 13 is resumed.

  Next, the configuration of the operation panel 80 will be described with reference to FIG. FIG. 4 is a plan view of the operation panel 80 arranged on the front surface of the spinning unit 2 in the spinning unit 2 provided in the spinning machine 1 according to the present embodiment. As shown in the figure, the operation panel 80 includes an overall view 81, abnormality display lamps 821, 822, 823, a 7-segment display 83, a maintenance call lamp 84, an operation switch 85, a level display unit 86, a trend The display unit 87 is mainly provided.

  As shown in FIG. 4, a simple overall view 81 of the side surface of the spinning unit 2 is drawn on the operation panel 80. The overall view 81 corresponds to the longitudinal sectional view of FIG.

  In addition, three abnormality display lamps 821, 822, and 823 made of light-emitting diodes are arranged in a vertical row in the vicinity of the side of the overall view 81. Each of the abnormality display lamps 821, 822, and 823 corresponds to a specific region in the overall view 81. In addition, the overall view 81 is divided into three parts in the vertical direction in order to clarify where the abnormality display lamps 821 to 823 correspond to the region from where in the overall view 81. Yes. That is, the area shown by the partial diagram divided into three parts in the overall diagram 81 corresponds to the abnormality display lamp arranged beside each partial diagram.

  With the above configuration, when there is an abnormality in the spinning unit 2, by turning on an abnormality display lamp corresponding to the abnormality occurrence position among the abnormality display lamps 821, 822, 823, the operator Can be notified. As described above, the abnormality display lamps 821 to 823 are arranged immediately next to the overall diagram 81, and the abnormality display lamp corresponding to the abnormality occurrence location is turned on, so that the portion corresponding to the abnormality occurrence location in the overall diagram 81 is displayed. It is configured so that it can be identified and displayed. As a result, it is possible to intuitively grasp where an abnormality has occurred in the spinning unit 2, so that when an abnormality occurs, the operator can immediately start maintenance work on the spinning unit.

  In addition, an abnormality occurrence location unidentifiable lamp 824 is provided to turn on when an abnormality has occurred at a location other than the above or when the location where the abnormality has occurred cannot be identified.

  The 7-segment display 83 is for displaying an error code at the time of occurrence of an abnormality. That is, in the spinning machine 1 of the present embodiment, the location where the abnormality has occurred can be intuitively grasped by the display using the overall view 81 and the abnormality display lamps 821 to 823, but by using the error code display by the 7-segment display 83 together. The operator can be notified of the details of the abnormality that has occurred in the spinning unit 2 in more detail.

  The maintenance call lamp 84 is for lighting in the spinning unit 2 that requires maintenance, and is configured to be brighter and more conspicuous than the abnormality display lamps 821 to 823 so that a remote operator can visually recognize the lighting state. Has been. The operator visually confirms the lighting of the maintenance call lamp 84 to grasp the position of the spinning unit 2 that needs maintenance, and aims at the maintenance call lamp 84 that is lit to perform the maintenance work. Move up.

  The operation panel 80 includes a plurality of operation switches 85. The operator can perform operations such as an emergency stop of the spinning unit 2 by appropriately operating the operation switch 85.

  Next, the level display unit 86 will be described. The level display unit 86 of the present embodiment is configured to display the operation state of the spinning unit 2 at five operation levels. Here, the “operation level” indicates a classification in which each spinning unit 2 is classified according to its operation state. Then, by looking at which operation level the spinning unit 2 is classified, the general operating state of the spinning unit 2 can be grasped.

  A part of the level display unit 86 is configured to be transparent or translucent, and configured to transmit light from the back side. Specifically, the first level display unit 861, the second level display unit 862, the third level display unit 863, the fourth level display unit 864, and the fifth level display unit 865 are each configured as a rectangular light transmission unit. Has been. Light emitting diodes (not shown) are arranged on the back side of the first to fifth level display portions. With the above configuration, any of the light emitting diodes can emit light, and any of the corresponding level display portions 861 to 865 can emit light.

  Further, the level display portions 861 to 865 are arranged in a staircase pattern as shown in FIG. 4, for example, so that the upper and lower relations of the driving levels can be understood graphically and intuitively. Specifically, the first level display portion 861 is arranged at the lowest position, and the fifth level display portion 865 is arranged at the highest position. That is, the first level display unit 861 represents the lowest operation level, the second level display unit 862, the third level display unit 863, the fourth level display unit 864, and the operation levels represented in order increase to the fifth level. It is configured so that the display unit 865 can intuitively grasp that it represents the highest driving level.

  With the above configuration, the operation level of the spinning unit 2 can be displayed by causing the level display unit 86 corresponding to the operation level of the spinning unit 2 to emit light. As a result, it is possible to intuitively know which operation level the spinning unit 2 is in among the five operation levels.

  In the present embodiment, the level display unit 86 is configured to always display the operation level of the spinning unit 2. Thereby, the operation level of the spinning unit 2 can be known on the spot without having to perform a special operation. Further, since it is not necessary to move to the machine control device 60 each time in order to confirm the operation state of the spinning unit 2 as in the conventional configuration, the work can be performed efficiently.

  Next, the trend display part 87 is demonstrated. Similar to the level display unit 86, the tendency display unit 87 is partly transparent or semi-transparent and configured to transmit light from the back side. Specifically, the upward arrow 871 and the downward arrow 872 are each configured as an arrow-shaped light transmission portion, and a corresponding light-emitting diode (not shown) is disposed on the back side. With the above structure, the upward arrow 871 and the downward arrow 872 can emit light.

  The upward arrow 871 is configured to emit light when the operating state of the spinning unit 2 is in an upward trend (a tendency to approach a higher level). Further, the downward arrow 872 is configured to emit light when the operation state of the spinning unit 2 is in a downward trend (prone to approach a lower level). When the operation state of the spinning unit 2 is level (when there is no upward or downward tendency), neither the upward arrow 871 nor the downward arrow 872 is caused to emit light.

  With the above configuration, the operator intuitively grasps whether the operation state of the spinning unit 2 is in an upward trend, a downward trend, or a flat state by checking the display of the trend display section 87. And appropriate measures can be taken.

  Next, a flow until the operation level of each spinning unit 2 is obtained and the operation level is displayed on the level display unit 86 will be described.

  First, the operator specifies in the machine control device 60 which operation data of each spinning unit 2 is to be used to determine the operation level. That is, the operating state of the spinning unit 2 includes, for example, the operating efficiency of the spinning unit 2, the thickness of the yarn detected by the yarn clearer 52 of the spinning unit 2, and the splicing error occurrence rate (yarn in the spinning unit 2). It can be expressed from various viewpoints such as a joint error rate. Further, the machine base control device 60 receives operation data from various sensors provided in the spinning unit 2, and based on the operation data, the operation efficiency, the yarn thickness, and the yarn splicing error are received. Various operation data such as the occurrence rate can be obtained.

  The operator can specify which operation data the operation level of the spinning unit 2 is determined by appropriately operating the input key 62 of the machine control device 60 and specifying a desired condition. Hereinafter, a case where it is specified that the operation level is obtained based on the operation efficiency of the spinning unit 2 will be described.

  When the above-mentioned designation is performed by the operator, the machine base control device 60 acquires the latest operation data of each spinning unit 2 through communication via each unit control unit 73. At the same time, the operation efficiency of each spinning unit 2 is calculated by appropriately referring to the operation data of the past certain period stored in the machine control device 60. The operating efficiency can be calculated, for example, as a value obtained by dividing the time during which the spinning unit 2 is actually operated during a certain period by the time during which the spinning unit 2 can be operated during the certain period.

  When the calculation of the operation efficiency for all the spinning units 2 is completed, the machine control device 60 next calculates the average value of the operation efficiencies of all the spinning units 2. At the same time, the machine control device 60 obtains the spinning unit 2 having the highest operating efficiency and the spinning unit 2 having the lowest operating efficiency among all the spinning units 2.

  Subsequently, the machine control device 60 obtains the operation level of each spinning unit 2 based on the operation efficiency. In the spinning machine 1 of the present embodiment, the level display unit 86 is configured to perform level display in five stages. Therefore, even in the machine control device 60, each spinning unit 2 is set at any of the five operation levels. Categorize. Which spinning unit 2 is classified into which operation level is arbitrary, but in this embodiment, each spinning unit 2 is classified into one of five operation levels as follows.

  First, the range of the third level which is the central level of the five levels is determined. The range of the third level is set so that the reference operation state that is the reference of the operation state is included in the third level. That is, the range of the third level is set so that the spinning unit 2 operating in the reference operation state and the operation state close to the reference operation state is classified into the third level. In the present embodiment, the reference operation state is an average value of the operation states of all the spinning units 2. Accordingly, among all the spinning units 2, the spinning unit 2 that is operating at an operating efficiency close to the average operating efficiency is classified into the third level.

  The spinning unit 2 not classified into the third level is classified into two levels above and below within a certain range from the third level. More specifically, the spinning unit 2 having an operating efficiency within a predetermined range from the operating efficiency (maximum operating efficiency) of the spinning unit 2 having the highest operating efficiency is classified into the fifth level. The spinning unit 2 having the operation efficiency between the fifth level and the third level is classified into the fourth level. Further, the spinning unit 2 having the operation efficiency within the predetermined range from the operation efficiency (minimum operation efficiency) of the spinning unit 2 having the lowest operation efficiency is classified into the first level. Then, the spinning unit 2 having the operation efficiency between the first level and the third level is classified into the second level.

  Next, the machine control device 60 determines whether the operating efficiency of each spinning unit 2 is increasing, decreasing, or leveling from the past operating efficiency history of each spinning unit 2. Judging.

  When the operation level classification and the tendency determination are completed for all the spinning units 2, the machine control device 60 transmits a level display request signal to the unit control unit 73. Each unit control unit 73 that has received the level display request signal causes the level display unit corresponding to the operation level in which the spinning unit 2 is classified among the level display units 861 to 865 of each spinning unit 2 to emit light. That is, if the spinning unit 2 is classified as the first level, the first level display unit 861 is displayed. If the spinning unit 2 is classified as the second level, the second level display unit 862 is displayed. Any one of 861 to 865 is caused to emit light, and the operation level of the spinning unit 2 is displayed. Further, each unit control unit 73 displays on the tendency display part 87 of each spinning unit whether the operational efficiency of the spinning unit is on an upward trend, a downward trend, or a flat state.

  Further, the machine control device 60 is configured to acquire the latest operation data from each spinning unit at regular intervals and recalculate the operation level of each spinning unit 2 based on the latest operation data. . The machine control device 60 transmits a level display request to each unit control unit 73 every time the operation level is recalculated, and displays the level display unit 86 and the trend display unit 87 of each spinning unit 2. Update. Thereby, the latest driving | running state can always be displayed.

  With the above configuration, the operator can grasp the general operation efficiency of the spinning unit 2 and take appropriate measures by checking the operation level displayed on the level display unit 86 of each spinning unit 2. it can. For example, when the level obtained based on the driving efficiency is displayed as described above, a high driving level indicates that the driving efficiency is high. Therefore, while it can be determined that the spinning unit 2 displayed with a high operation level does not require maintenance, the spinning unit 2 displayed with a low operation level requires maintenance (or maintenance improves operating efficiency). It can be easily determined that there is a relatively large room to be used).

  In the above description, the operation efficiency is described as an example. However, for example, when the operation level of the spinning unit 2 is obtained based on the yarn thickness, the spinning unit 2 with a thin yarn has a low operation level and the spinning unit 2 with a thick yarn. The spinning units 2 may be classified into a high operation level. In this case, since the thickness of the yarn is not preferable whether it is too thick or too thin, the spinning unit 2 is preferably operated at the center level (third level). The operator confirms the level display part 86 of each spinning unit 2, for example, the spinning unit 2 at the first level (the thickness of the yarn is too thin) or the fifth level (the thickness of the yarn is too thick) It can be easily determined that the spinning device 9 or the like needs to be adjusted.

  For example, when the operation level is obtained based on the yarn splicing error rate, the spinning unit 2 with a low splicing error rate is at a low operating level, the spinning unit 2 with a high yarn splicing error rate is at a high operating level, and so on. The spinning unit 2 may be classified. In this case, since the yarn splicing error rate is preferably low, the spinning unit 2 is preferably operated at a low operation level. The operator can easily determine that the spinning unit 2 having a high operation level needs maintenance by checking the level display section 86 of each spinning unit 2.

  Further, in the present embodiment, since the average value is set to the central level (third level) as described above, the operation efficiency of other units and the operation efficiency of the spinning unit 2 can be easily compared. That is, it is possible to easily determine at what operating efficiency the spinning unit 2 is operating.

  However, instead of the average value, for example, a range of the central level (third level) may be set with a predetermined set value as a reference operation state. According to this modification, it is possible to easily grasp how much the operating efficiency of each spinning unit 2 is operating in which direction the operating efficiency set by the operator is shifted in which direction. Alternatively, it is possible to easily grasp whether the spun yarn 10 being spun is thicker or thinner than a predetermined set thickness (reference thickness).

  Further, the operator can intuitively understand how the operation efficiency of the spinning unit 2 is changing by checking the display of the trend display unit 87. Therefore, for example, if the driving level is low, if it is on an upward trend, the situation will be observed for a while. If the driving level is high, if it is on a downward trend, attention will be paid. It is possible to respond flexibly, such as preparing for maintenance work and inspection work.

  Furthermore, in the present embodiment, the operator performs an appropriate operation on the machine base control device 60 to switch which operation data of the spinning unit 2 is determined based on the operation data during operation of the device. 86 can be displayed. For example, in the present embodiment, the operation level is switched based on the yarn thickness detected by the yarn clearer 52 of each spinning unit 2 or the splicing error occurrence rate (yarn splicing) in each spinning unit 2 is determined. It is configured to be able to switch to obtain the driving level based on the error rate.

  By making it possible to switch the operation data for obtaining the operation level in this way, it becomes possible to evaluate the operation state of the spinning unit from various viewpoints, and as a result, the spinning unit 2 can be more efficiently maintained. Can do.

  As described above, the spinning machine 1 according to the present embodiment includes a plurality of spinning units 2. Each spinning unit 2 includes a level display unit 86 that displays which operation level the operation state of the spinning unit 2 corresponds to among a plurality of operation levels.

  Thus, the operator can easily grasp the state of the spinning unit 2 by confirming the operation level of the spinning unit 2. Further, since each spinning unit 2 includes the level display unit 86, the operator can check the operation level on the spot. Therefore, the operator can easily grasp the spinning unit 2 that requires treatment, and can immediately perform the treatment on the spinning unit 2.

  Moreover, in the spinning machine 1 of this embodiment, the said operation level is divided so that the reference | standard reference | standard operation state may become a center.

  Thereby, it is possible to easily grasp whether the spinning unit 2 is at a higher operation level or a lower operation level than the reference operation state.

  In the spinning machine 1 of the present embodiment, the reference operating state is an average value of the operating states of the spinning units 2 provided in the spinning machine 1.

  Thereby, it can be easily grasped in which state the spinning unit 2 is operating with a deviation from the average value. Further, since the average value is used for the center level of the level display, it can be easily compared with the operation state of the other spinning units 2.

  Further, in the spinning machine 1 of the present embodiment, the reference operating state can be set to a predetermined set value.

  As a result, it is possible to easily grasp which direction the spinning unit 2 is operating from the set value.

  Further, the spinning machine 1 of the present embodiment is configured as follows. That is, the operation level of the spinning unit 2 is obtained based on the operation data in which the operation state of the spinning unit 2 is detected, and the spinning unit 2 can detect a plurality of types of operation data. The spinning machine 1 can switch which of the plurality of types of operation data is used to determine the operation level.

  That is, by making the display contents switchable, different types of information regarding the spinning unit 2 can be displayed by one level display unit.

  In the spinning machine 1 of the present embodiment, the operation level is at least one of the operation efficiency of the spinning unit 2, the yarn thickness of the spinning unit 2, and the yarn splicing error rate of the spinning unit 2. It can be obtained from either one.

  That is, since the operation data relating to the above-described operation state is frequently referred to by the operator, it is particularly preferable that the level display unit 86 of the present invention can display the operation data.

  In the spinning machine 1 of the present embodiment, each spinning unit 2 includes a tendency display unit 87 that displays whether the operating state of the spinning unit 2 is in an upward trend or a downward trend.

  Thereby, since the recent tendency of the operation state of the spinning unit 2 can be easily grasped, the operator can take an appropriate measure for each spinning unit 2.

  Although the preferred embodiment of the present invention and the modifications thereof have been described above, the above configuration can be modified as follows, for example.

  In the above description, the types of operation data are described as examples. However, any operation data that quantitatively represents the operation state (operation status, product quality, etc.) of the spinning unit 2 may be adopted. it can. For example, the operation level may be obtained based on the yarn speed, the number of times of yarn breakage, and the like.

  The operation level classification method is not limited to the classification based on the current maximum operation efficiency and the minimum operation efficiency of the spinning unit 2. For example, it can be classified as a fourth level when it is 5% to 15% higher than the average operating efficiency of the spinning unit 2, and as a fifth level when it is higher than 15%.

  The level displayed on the level display unit 86 may be a plurality of levels. For example, the level display unit 86 may display two levels or may display six levels or more. For example, in the case of 6 levels, the operation level can be divided so that the reference operation state corresponds to the boundary between the third level and the fourth level.

  The corresponding level display unit is displayed by turning on the light emitting diode. However, the present invention is not limited to this. For example, the light emitting diode may be blinked. Further, instead of the configuration in which the light emitting diode emits light from the back side through the light transmitting portion, a configuration in which the light emitting diode is exposed on the surface may be employed.

  You may comprise so that the level display part 86 may serve as a tendency display part. For example, when the driving level is currently the third level and tends to increase, a configuration in which the third level display unit 863 is turned on and the fourth level display unit 864 is blinked can be employed. In this case, the tendency display part 87 can be omitted.

  The operation panel 80 may be provided with an operation data content display section that displays what the operation level currently displayed on the level display section 86 is related to (such as operation efficiency or thread thickness). . This configuration is particularly preferable when the content displayed on the level display unit 86 can be switched.

  The level display unit 86 and the trend display unit 87 are not limited to the operation panel 80 and can be provided on any other members. However, from the viewpoint of improving visibility from the operator, it is preferable that the level display unit 86 and the like be arranged in front of each spinning unit 2.

  In the above embodiment, the machine control device 60 is configured independently of the prime mover box 5. However, for example, the machine control device 60 and the prime mover box 5 may be integrated.

  The unit controller 73 may be provided with one unit controller for each spinning unit 2, for example, instead of the configuration for controlling the four spinning units 2 as described above. Further, the unit control unit 73 may be omitted, and the machine control device 60 and each spinning unit 2 may be changed to a direct communication configuration.

  The yarn joining cart 3 and the automatic doffing device can be omitted. When the yarn joining cart 3 is omitted, the spinning unit 2 may be changed to a configuration including a yarn joining device.

  The configuration of the present invention is not limited to the spinning machine, and can be applied to other textile machines including a plurality of yarn processing units, such as an automatic winder including a plurality of winder units.
