摘要:
The invention refers to a weft-insertion-condition display method for a loom which includes a display device and in which a weft arrival time is detected each time a weft insertion operation is performed, the display device calculating statistics regarding the weft arrival times for each of predetermined sampling periods on the basis of the detected weft arrival times, storing the statistics that are sequentially calculated during a weaving operation in time series, and graphically displaying the stored statistics in time series along a time axis, wherein the weft-insertion-condition display method is characterized by comprising the step of: displaying information regarding a cause of variation in a travelling motion of a weft yarn on the same screen as a display screen on which the statistics are displayed the information being at least one of information regarding a reset operation for resetting the weft-insertion operational condition to an initial value after the weft-insertion operational condition is changed in the loom that performs a weft insertion control operation for changing a weft-insertion operational condition in accordance with weft arrival angles, information regarding a change in a weft insertion pattern, information regarding a change in a warp shedding pattern, information regarding a change in a weft density, and information regarding a change in rotational speed of the loom.
摘要:
A multiple-color weft inserting apparatus (60,70) of a fluid jet loom includes at least three weft supply lines (L), a weft-insertion controlling device (65,75). The controlling device (65,75) performs grouping of weft supply lines (L), and performs multiple-color weft insertion (60,70) in accordance with a predetermined weft-insertion pattern using the weft supply lines (L) in the group and at least one remaining weft supply line (L). The weft supply lines (L) in the group are where the weft of the same type is set. In the case where the controlling device (65,75) executes the insertion of the weft of the type corresponding to the group while the weft supply lines (L) in the group successively operate by turns, when the weft supply sensor (3) of any weft supply line (L) in the group detects a weft supply abnormality, the controlling device (65,75) excludes the any weft supply line (L) and continues the insertion of the weft of the type corresponding to the group using the other weft supply line or lines (L) in the group.
摘要:
A loom stores stoppage information including a step number each time the loom stops due to a weaving failure during a weaving operation, and displays an aggregation result on a display device (4) as operational information in response to a display request. The aggregation result is obtained by aggregating the stoppage information stored in a period before the time of issuance of the display request. The number of stoppages of the loom is aggregated for each of the step numbers to obtain aggregation results for the respective step numbers, and the aggregation results are displayed on the display device (4) in association with the respective step numbers.
摘要:
A loom includes a display device, and a weft arrival time is detected each time a weft insertion operation is performed in the loom. The display device calculates statistics regarding the weft arrival times for each of predetermined sampling periods on the basis of the detected weft arrival times, stores the statistics that are sequentially calculated during a weaving operation in time series, and graphically displays the stored statistics in time series along a time axis. Information regarding a cause of a variation in a travelling motion of a weft yarn (information regarding a replacement of a yarn supplier, information regarding a reset operation for resetting the weft-insertion operational condition, and information regarding a change in a weaving condition other than the aforementioned information) is displayed on the same screen as a display screen on which the statistics are displayed.

摘要:
A loom in which a weft arrival time is detected each time a weft insertion operation is performed includes a weft-insertion-condition display apparatus (20). The weft-insertion-condition display apparatus (20) calculates statistics (average, maximum and minimum values, and standard deviation) regarding weft arrival times detected in each of predetermined sampling periods on the basis of the detected weft arrival times, stores the statistics that are sequentially calculated during a weaving operation in time series, and graphically displays the stored statistics in time series along a time axis. An occurrence status of stoppages of the loom that have occurred in each of the predetermined sampling periods is displayed such that the number of stoppages can be visually recognized along the same time axis as the time axis along which the statistics are graphically displayed.
