Japanese Patent No. 2870384

  Textile factories have multiple textile machines of different production times and types. Manufacturers should manage and maintain substitutes in preparation for failure of the setting device, but since there are a wide variety of textile machines manufactured, it is necessary to maintain and manage many types of setting devices.

  In many cases, such a setting device is not compatible with processing software stored in a memory even though the hardware is actually compatible. In such a case, it is sufficient to replace only the software, that is, the ROM exchange or the program rewriting work, but it is necessary to have a dedicated tool, a program rewriting device, etc., and it is difficult for the user to carry out alone. is there.

  It is difficult to manage and maintain a large number of alternative parts for each type of textile machine shipped in preparation for failure at the user or agency side. As a result, there is a problem that when the setting device fails by the user, the failed textile machine must be stopped for a long period of time until a substitute is obtained from the manufacturer.

  Therefore, the subject of this invention is enabling it to prevent the long-term stop of the textile machine by the failure of a setting apparatus.

  Based on the above-described problems, the present invention displays information sent from the control device based on one or more control devices that control the actuator and a processing program stored in advance, and sets the input set values. In a textile machine having a display setting device that performs a display setting function to be sent to the control device, the control device records identification information determined according to the specification of the textile machine, and the display setting device includes: A plurality of processing programs corresponding to the identification information are stored in advance so as to be selectively executable corresponding to the identification information. After the textile machine is turned on, the display setting device selects a processing program corresponding to the identification information sent from the control device, and performs the display setting function.

  Here, the textile machine targeted by the present invention includes a warp preparation machine (a warp winding device, a gluing device, a warp warping machine, a beam rewinding machine, a weft preparation machine, a twisting machine, a rewinding machine), Includes a loom. Specifically, the identification information includes the machine specification of the textile machine (with / without optional equipment), the specification information of the control device (manufacturing time and software version information), and the machine type (model information). . The types of machines include machines that can be shared among different models, in addition to machines that differ depending on the thread type.

  More preferably, the processing program of the display setting device is created for a plurality of control devices having different identification information so that the program manufacturer always maintains upward compatibility over time. This makes it possible to reduce the types of supply parts. It is assumed that the processing program for executing the setting display function is such that the input items and display items of the set values differ depending on the machine specifications, and that such processing program is executed on the display setting device side. And Note that the method of receiving the identification information by the display setting device, that is, the initiative of communication may be on either the display setting device side or the control device side. Depending on the request of the display setting device, the control device side may reply, or the control device side may transmit unilaterally to the display setting device side.

  The control device is composed of a single controller or a plurality of controllers. In addition, the transmission of identification information is not limited to communication. For example, an identification information generator composed of a plurality of switches is provided independently of the control device. The identification information is decoded by a binary electric signal.

  According to the present invention, the display setting device selects a corresponding processing program from a plurality of processing programs stored in advance based on the identification information corresponding to the specification of the textile machine sent from the control device, By performing the display setting function, a so-called ROM exchange of a display setting device such as a conventional device can be performed without changing the so-called ROMs. Therefore, instead of having multiple types of alternative devices (display setting devices) for each textile machine in case of failure, it is only necessary to manage one type of display setting device for replacement that can be shared. , The number of holdings can be reduced and management becomes easier. Moreover, as a result of the smooth supply of the replacement device on the manufacturer side (agent side), the user can stop the textile machine for a long period of time until the repair of the faulty product is completed as in the past. Inconveniences such as significant decrease in performance are also eliminated.

  The different types of textile machines can include two or more of, for example, a warp winding machine, a warp gluing apparatus, a warp warping machine, a beam winding machine, etc., which are warp preparation machines. In addition, the processing programs are more specific about the identification information, such as the machine specifications of the textile machine (with / without optional equipment), specifications information of the control equipment (manufacturing time and software version information), machine The display setting device can selectively execute a plurality of processing programs corresponding to at least one of the identification information listed above. The display setting device can be shared among these many textile machines.

  The display setting device discriminates the identification information sent from the control device by executing the selection program, and selects the processing program corresponding to the identification information. The set value can be displayed, and the operating status of the textile machine can be accurately grasped.

  FIG. 1 exemplifies a warp winding device (warping machine) 1 that winds a sheet-like warp 3 drawn from a creel 2 into a take-up beam 4 as a sheet machine, that is, a warp preparation machine. Yes. In FIG. 1, a large number of warps 3 are drawn from a large number of yarn feeders 5 arranged on the creel 2, pass through a tensioner 6, and pass between upper and lower guide rolls 7, two press rolls 8, take-ups. After passing through the roll 9 and further the tension roll 10, the sheet is wound around the shaft (winding drum) of the winding beam 4 as a sheet.

  The shaft of the take-up roll 9 is connected to an auxiliary motor 11 as an actuator, and is thereby driven with a predetermined torque. The auxiliary motor 11 functions as a torque generating means for generating a predetermined torque, and, for example, by applying a torque in a direction against the traveling direction of the warp 3 to the take-up roll 9 while the warp 3 is traveling, A predetermined tension is applied to the warp 3. As a result of the warp 3 and the take-up roll 9 being brought into contact with each other by the two press rollers 8 and being not slipped, the take-up roll 9 rotates at the same speed as the traveling speed of the warp 3.

  The warp 3 is wound to apply tension to the warp 3 by winding. At this time, the winding tension of the warp 3 wound around the beam 4 is roughly the sum of the pulling tension from the creel 2 (tenser 6) and the tension applied from the take-up roll 9 (auxiliary motor 11). Therefore, the winding tension of the warp 3 can be set to a value different from the pulling tension from the creel 2 depending on the direction and force of the torque of the auxiliary motor 11. More specifically, when winding with a tension higher than the pulling tension applied by the creel 2, when the auxiliary motor 11 is caused to act in a direction against the running direction of the warp 3, and when winding with a low tension, The auxiliary motor 11 may be operated in the same direction as the traveling direction of the warp 3.

  The shaft of the winding beam 4 is connected to a winding motor 12 as an actuator, and is driven in the winding direction under a speed corresponding to a predetermined yarn speed in accordance with a change in the winding diameter. The winding diameter of the winding beam 4 is detected by the winding diameter sensor 14 and is sent to the control device 20 as an electrical winding diameter signal. A predetermined set tension is applied to the warp 3 by the torque acting on the take-up roll 9 and the tension applied from the creel 2 (tenser 6). The tension of the warp 3 is a tension sensor at the position of the tension roll 10. 13 is sent to the control device 20 as an electrical tension signal, and the output torque of the auxiliary motor 11 is controlled so as to maintain the winding tension. The yarn breakage of the warp 3 is detected as a yarn breakage signal by the warp sensor 15 between the take-up roll 9 and the tension roll 10.

  In addition to the tension signal from the tension sensor 13, the winding diameter signal from the winding diameter sensor 14, the yarn breakage signal from the warp sensor 15, the control device 20 is operated from the operation switch 16 for operation / manual / stop. , And signals and commands from the display setting device 21, generate drive outputs, and start / stop the auxiliary motor 11 and the take-up motor 12 via the current generators 30, 31, rotational speed, output torque Control etc.

The I / O port 23 receives signals from the tension sensor 13, the winding diameter sensor 14, the warp sensor 15 and the operation switch 16, and sends signals for controlling the auxiliary motor 11 and the winding motor 12. . The operation switch 16 includes an operation switch, an inching switch, a stop switch, and the like for the warp winding device 1.

  The first storage device 18 is configured by a nonvolatile memory (ROM) or the like, and stores a control program C. The control program C includes a system program for circuit operation of a programmable controller (PLC) and a machine control program created on the manufacturer side for controlling the warp winding device 1 as a textile machine. As will be described later, unique identification information B is attached to the control program C.

  The second storage device 19 is constituted by a volatile memory (RAM) or the like, and stores a winding length as various control data of the textile machine, recorded operation information of the textile machine, and the like. Even if the power supply is turned off for the temporary stop or suspension of the warp winding device 1, the second storage device 19 holds control data by a backup power supply (not shown). For this reason, the warp winding device 1 reads the control data immediately before the stop from the second storage device 19 when the operation is resumed after the temporary stop or after the stop period, and before the stop or before the stop period by the control data. Allows continuous operation in the operating state.

  The display setting device 21 includes a display setting controller 24 configured by a microcomputer (MPU), a display 25, a first storage 26, a second storage 27, and a port 28. The display setting controller 24 is connected to the display 25, the first storage device 26, the second storage device 27, and the port 28, and the port 28 can bidirectionally communicate with the port 22 of the control device 20. Connected in a normal state. The display setting device 21 displays information sent from the control device 20 on the basis of the processing program A stored in advance in the first storage device 26 and also displays the input setting values (setting data). The display setting function is performed in the process of setting the warp winding device 1 as a textile machine to an appropriate operating state based on the control program C.

  The display device 25 is configured by a general touch panel display device, and a touch panel is disposed on the display surface. When an operator touches the touch panel of the display unit 25, the display unit 25 analyzes the touched position on the touch panel, displays corresponding information according to a predetermined user program, and displays a set value (numerical value) or the like. A touch-sensitive numeric keypad is provided.

  The first storage device 26 is configured by a nonvolatile memory (ROM) or the like, and in addition to the selection program D and a plurality of processing programs A, that is, a display control program, writing of set values to the control device 20 and transmission of actually measured data. A communication control program such as reading is also provided. In accordance with the communication control program or the display control program, the controller 24 performs necessary processing, and periodically communicates with the control device 20 during the power-on period of the warp winding device 1, whereby information on the control device 20 is obtained. Is read and displayed on the display unit 25 in a form that can be visually recognized, such as numerical values, characters, or graphs.

  The second storage device 27 is configured by a volatile memory (RAM) or the like, and stores calculation data and the like on the display setting device 21 side. Even if the power supply is turned off to temporarily stop or pause the warp winding device 1, the second storage device 27 holds operation data and the like by a backup power supply (not shown). For this reason, when the operation is resumed after the temporary stop or after the suspension period has elapsed, the controller 24 can read the calculation data immediately before the stop from the second storage device 27 and can continue the calculation based on the calculation data. .

  The control device 20 and the display setting device 21 are communicably connected via ports 22 and 28 provided respectively, and convert information such as characters or numerical values into electrical signals according to a known protocol for transmission / reception.

  As described above, the control program C is stored in the first storage device 18 of the control device 20, and the processing program A1 is stored in the first storage device 26 of the display setting device 21, respectively. The controller 24 receives information transmitted from the display setting device 21 according to the control program C, and returns the necessary data while starting and stopping the auxiliary motor 11 and the winding motor 12 as actuators of the warp winding device 1. Controls rotation speed and torque. In addition, the processing program A1 displays information by switching a plurality of screens of the display 25, and transmits and receives information between the control device 20 and the display setting device 21, and a setting display function for inputting setting values. In order to execute the function to be performed, the program is created as a program having specific contents according to the function of the warp winding device 1.

  Further, in the control program C, unique identification information B is recorded according to the program content, that is, the function of the warp winding device 1. The control device 20 can return the identification information B via the port 22 in response to an inquiry from the display setting device 21. Although all the control functions of the warp winding device 1 can be performed by the control device 20 side, some of the control functions may be performed by the display setting device 21 side. For example, when the constant length stop function by the winding length is performed on the display setting device 21 side, the display setting device 21 counts the warp winding length from the pulse signal sent from the control device 20 side, and sets it to a predetermined preset length. When it reaches, a stop command is sent to the control device 20. At this time, the control device 20 stops the warp winding device 1 at a fixed length. The pulse signal is generated in proportion to the length of the warp 3 from a pulse-type length measuring device (not shown) on the travel path of the warp 3.

  The textile machine manufacturer creates a control program C for the control device 20 and a processing program A for the display setting device 21, and the textile machine in a state in which the control program C is incorporated into the control device 20 and the processing program A1 is incorporated into the display setting device 21. Supply to end users. Thereafter, on the maker side, the content of the control program C on the control device 20 side is changed because a new function is added to the textile machine or the allowable range of operating conditions allowed so far is expanded. Updated (added / deleted / changed). Correspondingly, the stored processing program A1 is updated (added / deleted / changed) on the display setting device 21 side, for example, because a new setting item is added or the allowable range of the setting value is changed. ) Is often done.

  Such a change of the processing program A1 on the display setting device 21 side is a significant change that cannot maintain compatibility with the display setting device 21 and the conventional control device 20 of the textile machine that has been manufactured conventionally. Sometimes accompanied. Of course, the incompatible processing program A2 cannot be applied to the conventional display setting device 21 or the conventional control device 20 after the change.

  Therefore, the present invention records unique identification information B, for example, identification information B1, according to the contents of the control program C determined in accordance with the specifications of the textile machine, and also displays the identification information B1 on the display setting device 21. In addition to the processing program A1 corresponding to, a plurality of processing programs A2,... An corresponding to other identification information B2,. The control program C on the control device 20 side is created so as to transmit the identification information B1 written in advance to the display setting device 21 side in response to a request from the display setting device 21 side. According to the selection program D stored in the first storage device 26 in advance, after the power is turned on, the identification information B1 is read from the control device 20 side, the suitability for the control device 20 is judged, and the suitable processing program A1 is selected. The display setting function is executed by displaying.

  The identification information B1, B2,... Bn is information specific to the control program C for selecting the processing programs A1, A2,. The information is determined according to the specifications of the textile machine and the control device 20, and includes the production time, the management information version of the software, etc., and is represented by any of letters, numbers, symbols, or a combination thereof. The

  3 shows an example of the structure of a plurality of processing programs A1, A2,... An and a selection program D of the display setting device 21. 3, the selection program D is in the first storage device 26 of the display setting device 21, and in order to identify the compatibility between the control device 20 and the display setting device 21, identification information B1, B2,. A processing program A1, A2,... An that conforms to Bn is selected.

  FIG. 4 shows another example of the structure of the plurality of processing programs A1, A2,... An and the selection program D of the display setting device 21. In FIG. 4, when a processing program a having the same contents exists in the processing programs A1, A2,... An, the processing program a is created as a sharable partial processing program, and other processing The programs A1, A2,. Thus, dividing the common part (processing program a) from the processing programs A1, A2,... An is advantageous because the storage capacity of the entire program can be saved.

  5 shows the selection of the processing programs A1, A2,... An that match the identification information B1, B2,... Bn by the selection program D of the display setting device 21, and the selected processing programs A1, A2,. The flow when executing An is shown. As described above, for example, identification information B1 determined corresponding to the specification as the textile machine is recorded in the control program C of the control device 20, and the identification information B1, B2,... Bn is recorded in the display setting device 21. A plurality of processing programs A1, A2,... An corresponding to are stored in advance so as to be selectively executable. In the example of FIG. 5, when the subscripts of the identification information B1, B2,... Bn and the subscripts of the processing programs A1, A2,.

  In FIG. 5, when the textile machine is turned on in step S <b> 1, the display setting device 21 requests identification information B from the control device 20. At this time, the control program C on the control device 20 side reads, for example, the identification information B1 written in advance corresponding to the contents of the control program C in response to a request from the display setting device 21 side. The data is sent to the display setting device 21 and stored in the second storage device 27 there.

  Thereafter, the display setting device 21 executes the processing from step S2 to step S9 according to the selection program D, and executes the selection processing of the processing program A corresponding to the identification information B read out earlier. More specifically, the selection program D is created as follows. First, in step S2, whether or not the identification information B read and stored in the second storage device 27 when the power is turned on is the identification information B1? (B = B1?) Is determined, and when yes, in step S3, the processing program A1 corresponding to the identification information B1 is selected. By executing the selected processing program A1, the controller 24 displays the information sent from the control device 20 on the display 25, and sends the input set value to the control device 20, thereby executing the display setting function. to continue. This execution is performed as long as the power is turned on, that is, in step S4, the power is turned off. As long as the determination is no, the process is repeated.

  Is the power off in step S4? When the determination is yes, that is, when the warp winding device 1 is stopped or enters a rest period, the processing program A1 step S10 is prepared in preparation for the restart of the warp winding device 1 after the stop or the elapse of the rest period. The control data is stored in the second storage device 27, and the series of processes is terminated.

  If the identification information B2 is recorded in the control program C, the controller 24 becomes no in the determination of step S2 and yes in the determination of step S5 as a result of the execution of the selection program D. The controller 24 selects the processing program A2 and executes it. Further, when the identification information Bn is recorded in the control program C, it becomes “no” in the determination in step S2 and step S5, and “yes” in the determination in step S7. Therefore, the controller 24 selects the processing program An, Will do it.

  However, when all determinations up to step 2, step 5, and step 7 are no, the controller 24 displays an alarm display (non-conformance of the display setting device 21) in the next step S9 as a result of execution of the selection program D. Processing is performed, and the display unit 25 displays that the control program 20 in which the control program C is stored cannot be handled.

  The control device 20 may be configured by a plurality of controllers 17, and the present invention is also applicable to the plurality of controllers 17. Assuming a format in which the display setting device 21 transmits and receives information between a plurality of controllers 17 of the control device 20 of the loom, for example, the control device 20 of the loom is configured by a plurality of controllers (CPUs) 17 and the display setting device. 21 is communicably connected to the plurality of controllers 17. When a plurality of, for example, three controllers 17 are controlled by different control programs C1, C2, and C3, unique identification information B11, B21, and B31 are recorded for each control program C1, C2, and C3. On the other hand, a processing program corresponding to identification information B11, B12,..., B21, B22,..., B31, B32,. A11, A12,..., A21, A22,..., A31, A32,. When starting the loom, the display setting device 21 sequentially selects and executes the processing programs A11, A21, and A31 corresponding to the identification information B11, B21, and B31 for each of the three controllers 17 by executing the selection program D. Will do.

  Preferably, the display setting device 21 can be shared among different warp preparation machines. Since the warp preparation factory has a warp winding device, a gluing device, a beam rewinding device, etc., the display setting device 21 can correspond to two or more of these machines. Thus, the display setting device 21 in a rest state can be used until the defective product is repaired. Manufacturers can easily manage substitutes (replacement parts) in the event of a failure, and the user can shorten the waiting period for obtaining substitutes.

  The method of transmitting the identification information B to the display setting device 21 is not limited to communication. As shown in FIG. 6, for example, an identification information generator 29 is provided separately from the controller 17 of the control device 20, and operation of the digital switch change key (+) or (−) of the identification information generator 29 in which numerical values can be set. Thus, necessary identification information B may be generated, and the identification information B may be directly transmitted to the display setting device 21 as an electrical signal.

  Of course, the present invention is not limited to a warp preparation machine, but can be applied to other textile machines such as a weft preparation machine and a loom. As described above, the types of textile machines can be shared among different types of machines as well as different textile machines depending on the yarn type.
