Description

Operation information display method of loom

technical field

The present invention relates to a method for displaying on a display device such as a CRT in association with the operation information obtained from the stop information of a loom and the step number of a weaving pattern.

Background technique

Patent Document 1 (Patent Publication No. 2004-100061) discloses a method for displaying operating information of a loom. If the loom stops during operation, the stop time, The method of displaying the stop information (stop reason) and the step number of the weaving pattern in time series as a list of stop history. In addition, the meaning of the weaving pattern, the step number, and the weaving cycle mentioned later will be explained in the best mode for carrying out the invention.

However, the display method according to Patent Document 1 has a disadvantage in that, since the stoppage information is only displayed in time series, the number of stoppage information to be displayed in a list increases with the increase in the number of stoppages. Stoppages are not limited to the weaving cycle (=weaving step) of a specific step number, so in the method in which the stoppage information is only displayed in a list as a history, it is difficult for workers to grasp the weaving steps and the occurrence of stoppages as it increases. status association. That is, if it is assumed that stoppages occur frequently in a specific weaving step, and the timing of its occurrence is dispersed in time series, in the conventional method, the same step number is displayed in a scattered manner, so that it is difficult to grasp how many stoppages occur in which weaving cycle. Second-rate.

If the worker can grasp the phenomenon that the platform stops frequently in a specific weaving step, then the worker can judge that there is a problem in the weaving action of the weaving step, such as the action time of the heald frame, etc. related setting states. If the problem is not solved in a timely manner, the operating rate of the loom will be reduced or the quality of the fabric will be reduced.

It should be noted that Patent Document 2 (Patent Publication No. Hei 9-195145 public record) discloses a method for displaying operating information of other looms. The method is to sequentially store data about loom stops (stop information ), is a method of summing up the stoppage information from the start time of the period specified in the display request to the current time with the generation of the display request, and displaying the summed result as the operation information.

However, the disadvantage of the display method according to this patent document 2 is that it only counts the number of stop times, or totals the number of stop times according to the cause of stop, and cannot grasp the number of stop times in relation to the weaving steps.

Contents of the invention

The present invention has been made in consideration of the above-mentioned problems, and the problem to be solved is to provide a method capable of quickly grasping in which weaving step how many times stoppages have occurred.

In order to solve the above-mentioned technical problems, the present invention is achieved through the following technical solutions: the present invention is based on the following loom. That is, according to the weaving pattern composed of a plurality of weaving cycles with step numbers in sequence, the weaving related elements are operated to weave, and every time the platform stops due to the occurrence of weaving failure during weaving, the stop including the step number is stored. The information is a loom that displays, as operation information, the result of summing up stop information from the start time of the period set with the generation of the display request to the current time on the display device.

The present invention can also be characterized in that the number of stoppages is totaled according to each step number, and the total number of stoppages is displayed on the display device according to each step number.

According to the present invention, since the weaving step (step number) at which weaving step (step number) can be easily grasped from the display of the display device and how many stops occur, it is possible to directly start the adjustment work of the weaving-related elements performed in the weaving step, and as a result, To improve the operating rate of the loom or improve the quality of the fabric.

It is also possible to display the total result in its state, but it is also possible to display it after further processing. For example, the invention of claim 2 is an invention in which the summed results are arranged in the order of the step numbers with the largest number of stoppages and displayed on the display device.

According to the invention of claim 2, since the step numbers are displayed in order of the number of machine stops, the weaving steps with the most number of machine stops can be grasped more easily, and the adjustment work can be efficiently performed.

It is also possible to classify stoppage information only by step number, but it is also possible to add other item classifications. For example, the invention of claim 3 is an invention in which totaling is performed for each stop cause, and the totaling result is displayed on the display device for each step number.

According to the invention of claim 3, since it is possible to grasp the weaving steps with a large number of stoppages according to the cause of the stoppage, it is possible to perform the adjustment work while paying attention to the weaving-related elements related to the cause of the stoppage.

The total period of the total stop times is the start time of the period specified by the display request, but the start time may be set arbitrarily so that the total results from other start times can be displayed. For example, in the invention of claim 4, the start time of the summing period for summing up the number of station stops can be set at any time, and the summing result from the aforementioned arbitrary time of the designated period to the current time can be displayed on the display device. Then, the total result from the start time of the specified period to the above-mentioned arbitrary time and the total result from the above-mentioned arbitrary time to the present time are displayed side by side on the display device.

According to the invention of claim 4, the total result can be grasped by comparing the results before and after the arbitrary time point, so that it is easy to judge whether the adjustment operation is successful or not.

The aggregated results may be displayed only for a single period, or may be displayed for each selectable plurality of periods. For example, in the invention of claim 5 , the display device is configured to selectively display a plurality of unit records with different periods, and to display on the display device a total result in the period of the unit record selected by the display request.

According to the invention of claim 5 , it is possible to grasp the total result of a desired unit record.

Detailed ways

As shown in Fig. 2 and Fig. 3, the loom used in this embodiment is an air-jet loom. An encoder 2 that detects a rotation angle (so-called crank angle) of the main shaft 1 and outputs a crank angle signal to a main controller 3 is connected to the main shaft 1 of the loom. The crank angle signal is used to generate a timing signal for the loom or to specify the drive of the driver.

The main control device 3 exchanges data with the display device 4 . Moreover, the main control device 3 outputs drive command signals to weaving-related components such as the illustrated weft insertion device or other unillustrated drive motors, braking devices, shedding devices, weft insertion devices, winding devices, and warp let-off devices. and so on, so that each weaving-related element performs a weaving action.

In the illustrated weft insertion device, a predetermined amount of weft yarn 6 drawn out from the yarn supply body 5 is wound around the length-measuring weft storage device 7 and stored. The length-measuring and weft-storing device 7 is composed of the length-measuring drum 8, the locking pin 9, and the driving solenoid 11 of the locking pin 9, and is controlled by any main control device 3. When weft insertion, the locking pin 9 is controlled by The set crank angle retracts and enters and exits, and becomes a released state in which the weft yarn 6 wound on the length measuring drum 8 in advance can only be unwound by one weft.

The weft yarn 6 is inserted into a not-shown warp opening through the main nozzle 12 , and is assisted by air passing through the servo nozzle 14 provided relative to the reed 13 . Solenoid valves 15 are provided between the main nozzle 12 and the pressure source, and between the servo nozzle 14 and the pressure source.

The solenoid valve 15 receives a drive signal output from the main controller 3 according to a predetermined crank angle, and controls ON/OFF of the air injected from the nozzles 12 and 14 by opening and closing. As a result, the weft yarn 6 discharged from the length-measuring weft storage device 7 is accurately inserted into the warp opening by the air jetted from the respective nozzles 12, 14.

On the side opposite to the weft insertion of the reed 13, H1 and H2 weft probes 16 and 17 are arranged to face the reed 13 at intervals. The outputs of the respective probes 16 and 17 are input to the main controller 3 through the probe 18 . Each of the weft feelers 16 and 17 is a sensor for detecting the presence or absence of the weft yarn 6 , and outputs a thread signal to the weft feeler 18 when the weft yarn 6 is detected. The H1 weft probe 16 is used for judging the success or failure of the weft insertion when the weft insertion is finished. The H2 weft feeler 17 is used to determine the presence or absence of weft breaks during weft insertion.

Between the H1 and H2 weft probes 16 and 17, there is an iron wire 19 for catching weft. The weft catch wire 19 holds the front end of the weft yarn 6, and is provided with a yarn breakage sensor 21 together with a tensioning unit (not shown) on the base end side in the warp direction. The yarn breakage sensor 21 outputs a yarn breakage signal to the main control device 3 . A warp breakage detector (dropper) 22 or a not-shown yarn breakage detector of the selvedge device 23 detects a not-shown warp yarn or side yarn 24 breakage, and outputs a yarn breakage signal to the main controller 3 .

The display device 4 connected to the main control device 3 is provided with: a display unit 27 such as a CRT or a liquid crystal panel, a setting unit 28 including a keyboard for performing various settings, etc. Simultaneously with the calculation, the CPU 29 controls the display content of the display unit 27, the memory 31 stores the calculation results by the CPU 29, and a time signal generator not shown. In addition, in the display device 4 , the display unit 27 has a touch panel, and the setting unit 28 may be formed of a touch panel. The main control device 3 is connected to an operation button 26 for instructing operation, stop, reverse rotation, inching, etc. of the loom.

During the operation (weaving) of the loom, if a machine stop factor occurs, a sensor corresponding to the occurrence part detects it and outputs a detection signal. This detection signal is input to the CPU 29 of the display device 4 via the main control device 3 . The CPU 29 stores the stoppage information in the memory 31 based on the input detection signal, calculates the operating information of the loom based on the stored stoppage information, stores it in the memory 31, and displays it on the display unit 27 according to the display request.

Here, the outage information is information used as a basis for acquiring operation information, and includes, for example, outage occurrence time, outage reason, and the like. Furthermore, the stoppage information of the present invention includes the step number when the cause of stoppage occurs. By the way, the reasons for stoppage are generally divided into broken weft and broken warp. Weft insertion errors such as short wefts or long wefts detected by the H1 weft probe 16 (H1 stop), weft insertion errors such as blown off or long wefts detected by the H2 weft probe 17 ( H2 stop), or the weft yarn is cut off on the upstream side of the main nozzle 12, etc. Furthermore, as warp breaks, ground warp yarn breaks detected by the warp breakage detector 22, weft catch wire breakages detected by the yarn breakage sensor 21, or edge yarn breakages detected by the yarn breakage detectors of the selvedge device 23 can be exemplified. .

Furthermore, the so-called operation information refers to various values calculated from the stop information, and includes, for example, the number of times of stop and the time of stop. Therefore, in the illustrated example, two types are shown as the stop frequency (FIG. 1). Specifically, the sum of the number of stoppages is totaled for each stoppage reason displayed on the lower stage of the display screen of the display unit 27, so that it is displayed on the display part shown by the symbol 27a in the upper stage of the display screen, and according to the present invention, each step Number total outage times. Furthermore, as the content displayed on the latter display part 27a, weft breakage is displayed as "horizontal" and warp breakage is displayed as "vertical" as the cause of station stop in the upper part, and the left and right are divided into "horizontal" and "vertical". The step number of the weaving pattern is displayed on the left side of each display area of the , and the number of stoppages is displayed on the right side, and the total result of the number of stoppages up to the current time within the specified period is displayed. In addition, the usual operation information is not limited to the information calculated based on the above-mentioned standstill information, including loom operation rate, number of revolutions, weaving thread length, etc. In the present invention, the operation information may also include these other information.

The period (total period) for totaling the number of outages refers to a period in which, in principle, a specific time in the past is defined as the start period (start time) and the current time is defined as the end period. This is because the display request is a request for grasping the operation information of the loom at the current time. However, the total period can also include specific periods in the past. That is, as described above, the display request is not limited to the case of ascertaining the operation information of the loom at the present time, and may include a request for ascertaining the operation information of the loom for a specific period in the past. In addition, the above-mentioned specific time in the past is a time specified by a preset period in which display is requested to grasp the operation information of the loom.

The so-called pre-set period required to display in order to grasp this loom operation information is, specifically, a work unit (for example, if it is 3 shifts, divide 24 hours a day into 3 equal parts every 8 hours), time Unit (for example, every 24 hours ago from the current time), day unit, etc. to set the period. In addition, in the present invention, the operation information displayed in each unit is collectively referred to as a unit record. Moreover, each unit record was previously called duty record, time record, and daily record in order.

In more detail, the duty record is loom operation information currently on duty. Furthermore, the time record is the loom operation information from the current time to the past A time (A=set value), and the day record is the loom operation information during the day. In addition, the above-mentioned later-mentioned past specific time corresponds to the start time of these unit recordings. It should be noted that, for the loom on which the present invention is based, the display device 4 is configured to display these multiple unit records, and can also selectively display any unit records, and the display device 4 can also be configured to only display any unit records. unit records.

Moreover, the so-called weaving pattern is a pattern for setting the operating state of each weaving-related element for forming one cycle of the fabric structure, and the operating state of each weaving-related element in each weaving cycle is set as a plurality of weaving cycles. pattern composition. In addition, the weaving cycle referred to here is one unit of weaving operation repeated every rotation of the main shaft 1 of the loom. Therefore, in the weaving pattern, each weaving cycle is assigned an ascending number in the order in which it is executed, and this corresponds to a step number.

The above-mentioned weaving pattern is set in the main control device 3 by a setting device not shown in the figure connected to the main control device 3 . The main control device 3 operates the respective weaving-related elements in order of the step numbers of the weaving pattern. Specifically, when the loom starts to operate, the main control device 3 receives the output from the encoder 2 and counts one rotation of the main shaft 1 per one rotation. Furthermore, the main control device 3 controls the operation of the weaving-related elements according to the operation state of the weaving cycle set in the step number according to the calculated value of the weaving pattern. If the calculated value reaches the total number of weaving cycles (steps) set in the weaving pattern, the main control device 3 clears the calculated value and controls the weaving related elements according to the setting of the first weaving cycle and repeats this action.

In the loom described above, the display method of operation information according to the present invention is carried out in the following manner.

First, if a cause of machine stop occurs during operation of the loom, it is detected by a sensor corresponding thereto, and a detection signal from the sensor is input to the main control device 3 . In this way, the main controller 3 turns off the loom operation signal to stop the loom. Furthermore, detection signals from the sensors are also input to the CPU 29 in the display device 4 via the main control device 3 . Like this, CPU29 reads as the step number of stopping information, reason of stopping (the kind of sensor), information (stopping generation time and day, duty information) etc. about unit record by main control device 3 and time signal generator. , are stored in the memory 31 in association with these. Then, the CPU 29 starts the measurement of the downtime according to the input of the detection information as necessary.

Thereafter, the worker repairs the cause of the stoppage and presses the running button of the loom, or the cause of the stoppage of the unillustrated automatic repair device is repaired, and the completion signal is output to the main control device 3, and the main control device 3 will The loom running signal is ON to restart the loom. It should be noted that the loom operation signal is turned ON and is terminated at the same time, and the above-mentioned measurement of the loom stop time is stored in the memory 31 in association with other loom stop information.

Thereafter, each time the loom stops, the above operation is repeated, and the stop information is stored in the memory 31 in time series to construct a database. When the amount of stoppage information exceeds the amount that can be stored in the memory 31, the stoppage information is sequentially deleted from the old information.

During the operation of such a loom, the worker performs an operation for displaying a desired unit record (for example, duty record) in order to grasp the operating state of the loom, and then instructs the display of the unit record (duty record) Commands are input to the CPU 29 . This display command is output to the CPU 29 by operating the setting unit 28 by a worker. And, at this time, this display command becomes a display request referred to in the present invention. Moreover, the display command (display request) is not limited to the command generated by the operator's operation as described above, and when a specific unit record is continuously displayed on the display unit 27, it is also included in every set period (for example, set time, Set the number of wefts, etc.) to automatically generate instructions. That is, when a specific unit record is continuously displayed, its display content can be automatically updated every the above-mentioned set period, and at this time, the signal for instructing its update becomes the above-mentioned display command (display request).

Next, the CPU 29 extracts the information during the total period in the current duty record from among the stoppage information stored in the database, based on the information about the unit record, that is, from the current movement start time to the current time, following the generation of the above-mentioned display command. stop information. Further, the CPU 29 first discriminates whether the cause of the stoppage is vertical or horizontal from the extracted stoppage information, and classifies the stoppage information for each stoppage cause. Next, the CPU 29 subclassifies the classified shutdown information for each of the same shutdown reasons for each step number, and sums up the number of shutdown information for each step number in the subdivided classification as the respective shutdown times.

Next, the CPU 29 creates log data for each step number that correlates the obtained total number of stop times and stop causes, and rebuilds another database that collects log data for each step number. Further, the CPU 29 stores the reconstructed another database in the memory 31, and extracts the upper N-th one from the other database in the order of the number of stops (N=set value/N=3 in the illustrated example) The above-mentioned record data up to now is used as a total result, and this total result is displayed on the display part 27a of the display part 27 as a part of the operation information in the duty record. And CPU29 calculates an operation rate, a station stop time, etc. by each calculation method, and displays it as another part of operation information.

It should be noted that the operation information displayed on the display unit 27 is not limited to the duty record as shown in the figure, and may also be recorded in other units such as the above-mentioned time record and daily record. At this time, the start period (start time) of the total period for counting the number of stop times is the time A hour (A=set value) before the current time in the case of the time record, and the time of the date in the case of the day record. The time when the loom operation started (0:00 p.m. of the day when the loom was continuously operated from the previous day). Further, the CPU 29 extracts from the database the stoppage information necessary for discriminating the operation information recorded by other units based on the information about the unit records.

Moreover, the unit records used to display the above-mentioned operation information are not limited to duty records, time records, and daily records. Each period from the time when the winding on the shaft starts to the cutting and unloading of the fabric), or each weaving pattern (every period of weaving with the same weaving pattern) is recorded. In this case, it is only necessary to construct a database if the stop information includes warp beams, winding beams, or information on weaving patterns. And, at least one of these unit records is a specified period accompanying the generation of the display request referred to in the present invention.

Furthermore, in the above-mentioned example, when constructing the database, the outage information is accumulated in the order of the chronological order of the outage causes, but the database may be constructed as in the following two examples.

In the 1st example, when the reason for stopping the station occurs every time, the CPU 29 temporarily stores the information of the step number, the reason for stopping the station, and the record of the unit in the memory 31, and judges whether the stopping information including the same step number and the reason for stopping the station has been registered in the A database (novelty) of other fields is stored in the memory 31 . And, in the novel case, the outage information is newly registered in the database, and the calculated value thereof is set to 1. And, if it is already registered, the calculated value of the registered station stop information is increased by 1. Then, when a display request occurs, stoppage information matching the request is extracted from the database based on the information about the unit record, and the summed results are similarly displayed on the display unit 27 thereafter. In addition, in this case, instead of summarizing the database in one table, the database may be constructed in separate tables for each stop cause (vertical and horizontal).

The second example is an example of constructing a database in the form of a matrix in which all the step numbers of the weaving pattern are registered. At this time, assign the step number to one side of the row or column, and assign the stop cause to the second horizontal and vertical items on the other side, and increase the calculation value of the cell corresponding to the table by 1 every time a stop cause occurs. Then, when a display request occurs, the total result is displayed on the display unit in the same manner based on the calculated value of the cell corresponding to the display request. In addition, it is also possible to construct a database by associating the summation period not only with the work unit for duty recording but also with other units.

In addition, the total result displayed on the display unit 27 is not limited to totaling for each stop cause as shown in the figure, and may be totaled only by the step number regardless of the stop cause. On the contrary, the summation result displayed on the display unit 27 may further subdivide the cause of stoppage. For example, the horizontal (broken weft) can be subdivided into H1 stop, H2 stop, broken yarn, etc., and the vertical (warp broken) can be subdivided into broken ground warp, broken weft catching wire, broken edge yarn, etc.

In addition, the total result displayed on the display unit 27 is not limited to displaying in order of the number of stop times (total number of times), but a list of stop times may be displayed in order of step numbers. At this time, when the total number of weaving cycles of the weaving pattern is large, all of them may not be displayed on the same screen. Therefore, in the total result displayed on the display unit 27, only the number of stop times greater than the set number is displayed in the list.

Furthermore, in the above example, the start time of the unit record displaying the total result is the start time for the total period of the total stop times, and only the total in the total period from the start date to the current time (end date) is shown. As a result, an arbitrary time in the operation of the loom can be used as the end of the total period so far, and further, an arbitrary time can be set as the beginning of the current total period, and the operator can set it separately. At this time, the display device 4 arranges and displays the preceding and following summation results at an arbitrary point of time on the display unit 27 , preferably in a comparable display. In order to perform this setting and display, the display device 4 sets a dedicated setting switch and a display switch in the setting unit 28, and secures a storage area for storing the summing results before and after an arbitrary time. Such setting and display are used in the following cases.

For example, in the case of displaying operation information as a shift log, at a certain point in time, it is known from the displayed summation result that there are extremely many stoppages at a specific step number (weaving cycle). At this time, it is judged that there is an abnormality in the operation of the weaving-related elements in this weaving cycle, so the operator needs to stop weaving and make adjustments (setting changes). Then, in order to easily judge whether or not the abnormal state has been eliminated through this adjustment, the worker performs as follows, and the display device 4 operated by the worker operates as follows.

The worker presses the dedicated setting switch during the adjustment time. The CPU 29 which receives the operation signal of the dedicated setting switch stores the summation results from the current movement start time up to that (up to the current time) in the dedicated storage area, and rearranges the summation results up to the current time. After the adjustment is finished, the CPU 29 is turned on again with the operation of the loom to add up. When the worker presses the dedicated display switch, or after the set time has elapsed, the CPU 29 reads the past total results stored in the dedicated memory area, arranges the present and the past, that is, the total results from before and after the adjustment work to the present and displays them. on the display unit 27 .

As a result, the worker can easily compare the current and past total results on the display unit 27, and can easily judge whether the abnormal state has been resolved. In addition, the total results of the present and the past are not limited to being displayed side by side, and may be displayed by switching the display screen.

In addition, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the claims.
