  Textile machines such as automatic winders and spinning machines are machines that are strongly required to improve production efficiency. Therefore, this type of textile machine is generally operated continuously throughout the day. The parts are heavily loaded. On the other hand, since the malfunction of the electronic component of the textile machine or the circuit board on which the electronic component is mounted is a direct factor in stopping the operation of the textile machine, it is particularly important to avoid the malfunction of the circuit board or the like.

  However, although the alarm device detects the temperature as a load on the circuit board, it does not store the temperature history and cannot refer back to past information even when an abnormality occurs. . Even if the function of the alarm device is applied to the textile machine, there is a problem that the maintenance process by the textile machine maintenance worker takes time in the event of an abnormality in the circuit board. That is, the maintenance process when an abnormality occurs is as follows: (1) In a textile factory, the circuit board where the abnormality has occurred is replaced with a new board and the setting values of the textile machine are adjusted, and (2) the textile machine design company, etc. , Analysis of the abnormal substrate and investigation of the cause, and (3) feedback of the cause of the abnormality to the textile factory and removal of the cause of the abnormality are necessary. Therefore, a lot of time and labor are required for the maintenance process.

  In addition, there is a possibility that the textile machine is operated with improper maintenance work. That is, the cause of abnormality of the circuit board is divided into an internal factor of the textile machine itself and an external factor other than the textile machine. When the cause of the abnormality is an external factor, even if the board is replaced or the set value is adjusted as in step (1) above, the circuit board abnormality may recur because the root cause is still unresolved. is there. Such a reoccurrence of the abnormality results in a loss of maintenance man-hours, circuit boards for replacement, and operation time of the textile machine in the step (1). In addition, since the designer of the textile machine cannot grasp the load information of the circuit board at the time of occurrence of the abnormality, the design improvement for reducing the load is not easy.

  In view of the above circumstances, an object of the present invention is to provide a textile machine and an information transmission system for the textile machine that facilitate the investigation of the cause of the abnormality even when an abnormality occurs in the circuit board.

  The yarn unwinding assisting device 12 assists the unwinding of the yarn from the yarn supplying bobbin 21. The tension applying device 13 applies a predetermined tension to the traveling yarn 20. When the clearer 15 detects a yarn defect and cuts the yarn, or when a yarn breakage during unwinding from the yarn feeding bobbin 21 is detected, the splicer device 14, The upper thread on the package 30 side is spliced. The clearer 15 monitors the presence and thickness of the traveling yarn 20. The clearer 15 includes a cutter (not shown), and immediately cuts the yarn 20 when a yarn defect such as a slab is detected. The lower thread guide pipe 25 is connected to a negative pressure source. After the thread 20 is cut, the thread end on the yarn feeding bobbin 21 side is sucked and captured and guided to the splicer device 14. Similarly, the upper thread guide pipe 26 is also connected to a negative pressure source. After the thread 20 is cut, the thread end on the package 30 side is sucked and captured and guided to the splicer device 14.

  Further, the winding unit main body 16 includes a cradle 23 that rotatably holds a winding bobbin that is a core tube of the package 30, and a traverse drum 29 that traverses the yarn and drives the winding bobbin. ing. A spiral traverse groove is formed on the outer peripheral surface of the traverse drum 29, and the yarn 20 is traversed by the traverse groove. The traverse drum 29 is driven to rotate, and the package 30 in contact with the circumferential surface of the traverse drum 29 is driven to rotate by the traverse drum 29, whereby the yarn 20 is wound up as the package 30.

  Next, the configuration of the central control box 90 will be described in detail. The central control box 90 includes a housing disposed at the end of the automatic winder 1 and controls the entire automatic winder 1 in an integrated manner. As shown in FIG. 3, the central control box 90 includes a unit central control unit (control unit) 61 stored inside the housing, and a touch panel display 94 provided outside the housing. . The unit central control unit 61 performs various information processing according to a program. The touch panel display 94 has the functions of the display unit 92 (FIG. 2) that outputs the result of information processing as a screen display and the setting unit 91 (FIG. 2) that receives various input operations by maintenance personnel. The central control box 90 also includes a warning lamp (abnormality notification unit) 95 for notifying maintenance personnel of abnormalities in operation and a control printed circuit board 96 on which various electric circuits are formed.

  The unit central control unit 61 is physically configured as an electronic component including a CPU, a RAM, a ROM, and the like. The unit central control unit 61 also includes an information storage unit (load value history storage unit) 61a that stores information, an information organization unit (load value history information organization unit) 61b that organizes stored information, and a touch panel display 94. And a display calculation unit 61c for creating a display screen. The information storage unit 61a, the information organizing unit 61b, and the display calculation unit 61c are realized in software by the hardware of the unit central control unit 61 such as the CPU, RAM, and ROM operating in accordance with a program. Is a component to be For example, the information storage unit 61 a is realized as a part of the information storage area included in the RAM of the unit central control unit 61.

  Further, a plurality of AC-DC converter boards 62 are stored inside the housing of the central control box 90. The AC-DC converter board 62 AC-DC converts the power supplied from the power supply unit (power supply source) 99 and supplies it to the winder unit 10. Here, one AC-DC converter board 62 is configured to supply power to a plurality of winder units 10. For example, when the automatic winder 1 includes 72 winder units 10, six AC-DC converter boards 62 are provided, and one AC-DC converter board 62 supplies power to 12 winder units 10. The AC-DC converter board 62 is a printed circuit board on which a large number of electronic components are mounted. A cooling fan 63 is provided in the vicinity of each AC-DC converter board 62. The cooling fan 63 is driven by a cooling fan motor (cooling fan driving unit) 63 a and sends cooling air to cool the AC-DC converter board 62. The cooling fan 63 is configured to circulate cooling air inside the centralized control box 90. Therefore, by driving the cooling fan 63, not only the AC-DC converter board 62 but also various electronic components stored in the centralized control box 90 are cooled.

  In addition to the AC-DC conversion circuit, the AC-DC converter board 62 is provided with load value detection means for quantitatively detecting various loads applied to the AC-DC converter board 62. The load value detecting means includes a temperature sensor 62a for measuring the temperature at the place where the AC-DC converter board 62 is installed, a voltage monitor circuit 62b for measuring a voltage applied to the AC-DC converter board 62, and an AC-DC converter board. And a current sensor 62 c that measures the value of the current flowing through 62. The temperature sensor 62 a, the voltage monitor circuit 62 b, and the current sensor 62 c are mounted on the AC-DC converter board 62.

  The temperature sensor 62a sequentially transmits the measured temperature value at each time point to the unit central control unit 61 as an electrical signal. Here, the temperature value at each time point is a temperature value periodically measured at predetermined time intervals (for example, at intervals of 10 seconds). In the information storage unit 61a of the unit central control unit 61, temperature value history information that associates the measurement time with the temperature value is accumulated and stored as electronic data. Similarly, the voltage value obtained by the voltage monitor circuit 62b and the current value obtained by the current sensor 62c are also associated with the measurement time and accumulated and stored in the information storage unit 61a as history information. Furthermore, the power value obtained by multiplying the voltage value and the current value is also stored in the information storage unit 61a as history information in association with the measurement time.

  Hereinafter, the history information accumulated and stored in the information storage unit 61a is referred to as “temperature value history information”, “voltage value history information”, “current value history information”, “power value history information”, etc., respectively. Called. Further, quantitative values of the load applied to the electronic circuit board included in the automatic winder 1 such as the temperature value, the voltage value, the current value, and the power value are collectively referred to as “load value”. Also, load value history information is collectively referred to as “load value history information”. Since each of these load value history information is stored as electronic data in the information storage unit 61a, the maintenance personnel can compare each load value history information with the subsequent load values as compared with the case where the load value history information is stored on a medium such as paper. The history information can be handled efficiently.

  If the load such as temperature, voltage, current, and power applied to the AC-DC converter board 62 is excessive, electronic components mounted on the AC-DC converter board 62 are damaged, and the AC-DC converter board 62 functions. There is also a risk of not. For example, when the automatic winder 1 is operated under an abnormal environment in which the air conditioning of the textile factory is not activated, the temperature at the place where the AC-DC converter board 62 is installed becomes high, which is caused by the temperature load. The possibility that the AC-DC converter board 62 will not function increases. Further, even when each setting of the automatic winder 1 is inappropriate and power consumption is high, the temperature of the AC-DC converter board 62 becomes high, and the AC-DC converter board 62 may not function due to a temperature load. Will increase.

  When the factory voltage is abnormal, an excessive voltage may be applied to the AC-DC converter board 62, and the AC-DC converter board 62 may not function due to a voltage load. . Even when the discharge circuit of the AC-DC converter board 62 itself is abnormal, an excessive voltage may be applied to the AC-DC converter board 62, and the AC-DC converter board 62 is caused by the voltage load. May be damaged. In addition, when an overload is applied to the rotation of the traverse drum 29 due to a bearing failure or the like, an excessive current may flow through the AC-DC converter board 62, and the AC-DC converter board is caused by the current load. 62 may be damaged.

  Therefore, in the unit centralized control unit 61, the lower limit temperature load value, voltage load value, and current load value, which are considered to increase the possibility of damage to the electronic components mounted on the AC-DC converter board 62, respectively, It is registered as “critical temperature value”, “critical voltage value”, and “critical current value”. These critical load values are input and set in advance from the touch panel display (criticality setting unit) 94 by maintenance personnel and stored in the information storage unit 61a. The unit central control unit 61 performs a process of reducing the load value when a value equal to or higher than the critical load value is detected. As a result, the AC-DC converter board 62 can be prevented from being damaged and a high load on the AC-DC converter board 62 can be avoided, so that the life of the AC-DC converter board 62 can be extended.

  As a specific example of the above processing, when the temperature detected by the temperature sensor 62a is equal to or higher than the critical temperature value, the unit central control unit 61 transmits a drive signal to the cooling fan motor 63a, and the cooling fan 63 is driven. As a result, the AC-DC converter board 62 is cooled by the cooling air, the temperature is lowered, and the AC-DC converter board 62 is prevented from being damaged. At this time, the unit central control unit 61 stores a drive history indicating that the cooling fan 63 has been driven in the information storage unit 61a. As a result, information indicating that there is an overload on the AC-DC converter board 62 is stored as a history, and the maintenance personnel can investigate the cause of the drive history when the AC-DC converter board 62 is later damaged. Can be used.

  As another specific example of the above processing, when the temperature value detected by the temperature sensor 62a is equal to or higher than the critical temperature value, the unit central control unit 61 determines that the voltage value detected by the voltage monitor circuit 62b is the critical voltage value. If it is above, or if the current value detected by the current sensor 62c is greater than or equal to the critical current value, the operation of the automatic winder 1 is stopped. As a result, overloading of the AC-DC converter board 62 is avoided, and damage to the AC-DC converter board 62 is prevented in advance. At this time, the unit central control unit 61 stores the operation stop history indicating the operation stop in the information storage unit 61a. As a result, information indicating that there is an overload on the AC-DC converter board 62 is stored as an operation stop history, and the maintenance personnel can display the operation stop history when the AC-DC converter board 62 is damaged later. It can be used to investigate the cause.

  Further, the unit central control unit 61 determines that the temperature value detected by the temperature sensor 62a is greater than or equal to the critical temperature value, the voltage value detected by the voltage monitor circuit 62b is greater than or equal to the critical voltage value, or the current sensor 62c. In any case where the current value detected in (1) is equal to or greater than the critical current value, it is determined that the operation is abnormal, a drive signal is transmitted to the alarm lamp 95, and the alarm lamp 95 is turned on. Thereby, the maintenance staff can prevent the AC-DC converter board 62 from being damaged by knowing the abnormal event and taking appropriate measures. At this time, the unit central control unit 61 stores an alarm history indicating that an operation abnormality alarm has been performed in the information storage unit 61a. As a result, information indicating that there is an overload on the AC-DC converter board 62 is stored as an alarm history, and when the AC-DC converter board 62 is damaged later, the maintenance personnel investigate the cause of the alarm history. Can be used.

  Further, the unit central control unit 61 determines that the temperature value detected by the temperature sensor 62a is greater than or equal to the critical temperature value, the voltage value detected by the voltage monitor circuit 62b is greater than or equal to the critical voltage value, or the current sensor 62c. When the current value detected in step S1 is equal to or higher than the critical current value, a message prompting an operation for setting these values to normal values is displayed on the display unit 92. The message displayed on the display unit 92 includes, for example, a message prompting confirmation of the operation status of the cooling fan 63 when an overload occurs on the AC-DC converter board 62, and a message in the housing of the central control box 90. There is a message that prompts the user to clean the filter to release heat.

  In the automatic winder 1, there are a large number of electronic circuit boards that may be damaged due to overload, including the AC-DC converter board 62. As a typical example of such an electronic circuit board, a printed circuit board for control 96 built in the housing of the centralized control box 90, a printed circuit board 81 built in the automatic doffing device 80, and the winder unit 10 are used. There is a printed circuit board 53 incorporated in the unit controller 50. In the following, this type of electronic circuit board existing in the automatic winder 1 is generically referred to as a “substrate”, and when these substrates are distinguished from each other, “substrate 62”, “substrate 96”, “substrate 81”. "," Substrate 53 ", etc.

  The configuration in which the load value history information related to the substrate 62 as described above is stored and stored, and the configuration for preventing the substrate 62 from being damaged due to the load are similarly applied to the substrates 96, 81, and 53. Furthermore, it can be applied to any other electronic circuit board disposed in the automatic winder 1. In the example of FIG. 3, the substrates 96, 81, and 53 are also provided with a temperature sensor 62a, a voltage monitor circuit 62b, and a current sensor 62c, respectively, and temperature value history information and voltage for each substrate 96, 81, and 53 are provided. It is assumed that value history information, current value history information, and power value history information are accumulated in the information storage unit 61a.

  In particular, a vibration sensor 53 a for detecting vibration is further provided on the substrate 53 provided in each winder unit 10. Here, since the winder unit 10 rotates the package 30 at high speed, the winder unit 10 easily vibrates due to factors such as eccentricity of a rotating portion (for example, a winding bobbin that winds up the package 30). Therefore, the substrate 53 arranged in the winder unit 10 is easily affected by the vibration, and this vibration becomes a load on the substrate 53. Therefore, the vibration of the substrate 53 is sequentially detected by the vibration sensor 53a so that the “vibration history information” is accumulated and stored in the information storage unit 61a, and damage to the substrate 53 due to the vibration load is prevented in advance. be able to. Specifically, a slave board, an I / O slave board, etc. that perform motor control correspond to the board 53.

  In addition, the information organizing unit 61b of the unit central control unit 61 discards load value history information that is relatively low in importance. Specifically, the information organizing unit 61b leaves only the load value information in the time zone of a predetermined width before and after the time when the load value equal to or higher than the critical load value is detected in the load value history information, and other load values Information is discarded from the load value history information. Further, the information organizing unit 61b may perform processing of discarding the remaining load value information in order from the oldest information and preferentially leaving the new information. Further, the information organizing unit 61b may associate the importance level of the alarm in the automatic winder 1 with the load value history information, and perform a process of discarding the information in descending order of importance. By the processing of the information organizing unit 61b as described above, the data capacity of the load value history information is reduced, and only important information related to the breakage of the electronic circuit board is collected in the load value history information.

  In the automatic winder 1, in the unlikely event that a substrate such as that described above is damaged, maintenance personnel must investigate the cause of the damage. In the automatic winder 1, as described above, each load value history information is stored in the information storage unit 61a. Therefore, the maintenance staff reads each load value history information and uses it for the subsequent cause investigation. Can do. In order to support such maintenance work by the maintenance personnel, the unit central control unit 61 can visually display each load value history information on the touch panel display (load value history display unit) 94.

  Hereinafter, the screen display of the load value history information will be described with reference to FIGS. Each display screen described below is created by the calculation of the display calculation unit 61 c of the unit central control unit 61 and displayed on the touch panel display 94. Further, “input” in the following description is performed by a predetermined touch input operation on the touch panel display 94. In addition, in order to allow maintenance personnel to perform a touch input operation, a known method such as pressing a touch operation button arranged on the screen may be used, so an explanation of the operation, a touch operation button on the screen, etc. Illustration is omitted. In addition, illustrations of screen display portions that are not necessary for the description are omitted as appropriate.

(List display mode of load value history information)
First, temperature value history information, voltage value history information, current value history information, and power value history information relating to each of the substrates 62, 96, 81, and 53 are read from the information storage unit 61a. Then, as illustrated in FIG. 4, a table B <b> 1 is displayed in the upper screen area A <b> 1 of the touch panel display 94. In the table B1, the temperature value, voltage value, current value, power value, and accumulated operation time of each board corresponding to an arbitrary time are displayed as numerical data. In the example of FIG. 4, the substrate 96 (main body substrate), the substrate 81 (doffing device substrate), the first substrate 62 (AC-DC 1), and the second substrate 62 (AC-DC 2) are arranged in four rows. However, the display is switched to the display of the information column regarding other substrates by a predetermined screen switching operation (for example, a scroll operation in the horizontal direction of the screen).

  In addition, in the table B1, when a load value equal to or higher than the critical load value is included, the character of the load value is highlighted. The highlighting may be in any form as long as it is a noticeable appearance with a different appearance from other characters. For example, the highlighting is displayed in a color different from that of other characters, or an arrow is attached to the character. Or displaying a pointer of the screen. By such highlighting, maintenance personnel can more clearly grasp information on load values that are equal to or higher than the critical load value when checking the load value history display unit.

  In this screen, maintenance personnel specify and input one of the load value items, the change of the load value of the specified item is graphed, and the load value graph with the horizontal axis as the time axis (load value change) Graph) B2 is displayed in the lower area A2 of the screen. The calculation for graphing the load value history information is performed by a display calculation unit (graph conversion processing unit) 61c. In the example of FIG. 4, by designating the temperature value, the characters “temperature value” in the table B1 are highlighted, and the transitions of the temperature values related to the respective substrates 96, 81, 62, 62 are graphed. B2 are displayed so as to overlap each other. Here, four curves appear to overlap in the graph B2, but the colors of the four curves are displayed separately and can be distinguished. Here, it is also possible to display the transition of the temperature value for any one selected substrate alone in the graph B2 by a predetermined designation input.

  At this time, if the maintenance worker designates and inputs an arbitrary time on the horizontal axis of the graph with the time designation button displayed below the graph B2 on the touch panel display (time point designation unit) 94, the designated time Each temperature value is displayed in the table B1. In the example of FIG. 4, “March 3 17:30” is designated as represented by the broken line in the graph B2, and correspondingly, the table B1 includes March 3 17:30. The temperature value of each substrate at is displayed. With this function, the maintenance staff can specify a desired arbitrary time point on the touch panel display 94 and can quickly check the load value at the desired time point, so that maintenance work can be performed more efficiently.

  While the screen of FIG. 4 is being displayed, the maintenance staff can select another load value item and switch the graph B2 displayed in the lower area A2 of the screen. For example, when the “voltage value” column of the table B1 is touched on the screen of FIG. 4, the “voltage ground” character in the table B1 is highlighted and the graph B2 is displayed as illustrated in FIG. Then, the graph switches to a graph of voltage values related to the substrates 96, 81, 62, 62. Such a graph display allows maintenance personnel to visualize the transition of each load value and visually confirm it, making it easier to investigate the cause of damage, and as a result, The accuracy can be further improved.

(List display mode for desired load value history information)
In this display mode, as illustrated in FIG. 6, loads related to the substrate 96 (main substrate), the plurality of substrates 62 (AC-DC substrate), the substrate 81 (doffing device substrate), and the plurality of substrates 53 (unit substrate). A table C1 showing a list of values is displayed in the upper area A1 of the screen. In the example of FIG. 6, the temperature value of each substrate is displayed, but the table is switched to a table showing other load values (power value, voltage value, current value, vibration value) by a predetermined operation. In the example of FIG. 6, the temperature values on a large number of substrates 62 and a large number of substrates 53 are respectively displayed in a horizontal row. For example, in the row of “unit board”, only the data of six boards 53 appears, but when a predetermined screen switching operation (for example, scrolling operation in the horizontal direction of the screen) is performed, the other boards 53 are related. Switch to the information column display.

(Alarm history list display mode)
In this display mode, as illustrated in FIG. 7, the above-described alarm history stored in the information storage unit 61 a is displayed as a list. In the example of FIG. 7, the alarm date / time, the board related to the alarm, the unit number of the winder unit 10, the importance of the alarm, the alarm information indicating the alarm content, and the alarm code are displayed in the table. ing. Further, the maintenance staff can specify and input a desired substrate from the screen of FIG. 7, and can extract and display only the alarm history related to the specified substrate as illustrated in FIG. In FIG. 8, by designating the substrate 53 of the winder unit 10 having the unit number 7, only the alarm history regarding the substrate 53 is selectively displayed.

  Then, the effect by the automatic winder 1 which was demonstrated above is demonstrated.

  In the automatic winder 1, load value history information of the substrates 62, 96, 81, and 53 at each time point is accumulated and stored in the information storage unit 61a. Therefore, even when the boards 62, 96, 81, 53 are damaged, the maintenance personnel can refer to the stored load value history information afterwards to use it for investigating the cause of the damage. Therefore, according to the automatic winder 1, maintenance personnel can easily investigate the cause of damage to the substrates 62, 96, 81, 53. If the cause of the damage is found only by referring to the load value history information, the damaged board itself may not be exchanged with maintenance personnel, and the cause of the damage can be investigated quickly.

  As a result, the operating rate of the automatic winder 1 is improved, and as a result, the production efficiency is improved. In addition, if the cause of the damage is clarified, it is possible to fundamentally solve the cause of the damage. Therefore, it is possible to prevent the automatic winder 1 from being operated with improper maintenance work. Loss is avoided in the operation time of the replacement circuit board and the textile machine.

  Further, the designer of the automatic winder 1 can obtain information on the load on the substrate of the automatic winder 1 that is actually operated in the textile factory by obtaining the load value history information. Therefore, the designer must accurately recognize the operating environment and operating conditions, such as the climate of the land where the automatic winder 1 operates, the air condition of the factory, and the voltage of the factory power supply, and then efficiently design to reduce the load on the board. Improvements can be made.

  In the automatic winder 1, load value history information is displayed on the touch panel display 94. If there is no such display unit, it is necessary to connect another display device accessible to the unit central control unit 61 to read and display the load value history information. On the other hand, in the automatic winder 1, the maintenance staff can display the load value history information on the touch panel display 94, and can quickly investigate the cause of the damage by omitting the above operation.

  In the automatic winder 1, load value history information is stored for a plurality of substrates, and information on a plurality of types of load values for a plurality of substrates can be switched and displayed. With this configuration, the maintenance staff can identify the damaged part and estimate the cause of the damage while comparing the load value information regarding the plurality of electronic circuit boards and considering the correlation between the information. Therefore, the maintenance worker can specify the damaged part more accurately and estimate the cause of the damage in more detail.

  Further, in the automatic winder 1, the load value of the board to be detected includes the temperature value of the board installation location, the voltage value supplied to the board, the current value supplied to the board, and the vibration value generated on the board. It has been adopted. Maintenance personnel can efficiently narrow down maintenance work necessary to restore the operation of the automatic winder 1 by grasping such load values. In other words, the automatic winder 1 can comprehensively grasp the voltage value, the temperature value, the vibration value, which are load values that change due to environmental factors, and the current value, which is the load value that changes depending on electrical factors, as load values. It is configured. The power value calculated from the current value and the voltage value is also stored as load value history information, which is useful information for efficiently narrowing down the maintenance work required to restore the operation of the automatic winder 1. obtain.

  In the automatic winder 1, in particular, the load value of the AC-DC converter board 62 is monitored and stored as load value history information. Since the AC-DC converter board 62 is interposed and connected between the power supply unit 99 and the winder unit 10, the state of the power supply unit 99 and the winder unit 10 are monitored by monitoring the AC-DC converter board 62. The information reflecting both of these states is obtained as the load value history information. Therefore, the information collection efficiency is improved, and the load value history information is useful information for improving the design of the automatic winder 1.

  Next, an information transmission system 300 shown in FIG. 9 will be described as an embodiment of the information transmission system of the present invention.

  As shown in FIG. 9, each automatic winder 1 installed in a textile factory in each region is automatically connected to a remote history management computer terminal (history information management unit) 301 via a network 303. An information transmission system 300 related to the winder 1 is constructed. As the network 303, a dedicated network may be constructed, or the Internet may be used. The central control box 90 of each automatic winder 1 includes a history information output unit 97 (FIG. 3) including a communication port and the like, and the load value history information accumulated in the information storage unit 61a is stored in the history information output unit 97. Via the network 303. Then, the load value history information is delivered to the history management computer terminal 301 through the network 303.

  The cause of damage to the substrate of the automatic winder 1 is determined by a simple maintenance that can be investigated by general maintenance personnel at each textile factory where the automatic winder 1 is present, and by an advanced maintenance worker who has knowledge equivalent to the designer of the automatic winder 1 There is something advanced to do. Therefore, in the past, when the substrate of the automatic winder 1 in a textile factory was damaged, the general maintenance staff first investigated the cause, and for those things that could not be investigated by the general maintenance staff, asked the senior maintenance staff at a remote location to investigate the cause. There were many cases where was made.

  On the other hand, according to the information transmission system 300 described above, by arranging the history management computer terminal 301 based on the senior maintenance personnel, the senior maintenance personnel can obtain the load value history information without bothering the general maintenance personnel. It can be obtained. A senior maintenance worker in a location remote from the automatic winder 1 can directly investigate the cause of the substrate damage. Further, remote maintenance of the automatic winder 1 can be performed by senior maintenance personnel even when the substrate is not damaged. Further, by arranging the history management computer terminal 301 on the basis of the designer of the automatic winder 1, the designer can collect and obtain information on substrate breakage of each automatic winder 1 from each remote fiber factory. The automatic winder 1 can be efficiently improved in design. Further, according to the information transmission system 300, it is possible for the general maintenance staff to solve the abnormality of the substrate of the automatic winder 1 while receiving an instruction from the senior maintenance staff at a remote place. Therefore, in this case, it is possible to reduce the possibility that the automatic winder 1 is operated with improper maintenance work and the substrate abnormality reoccurs.
