    摘要: Motor-driven let-off and take-up motions in a loom are controlled by controlling the rotation of a motor for driving warp yarns with a tension control system operating in response to a signal indicative of a target tension and a feedback input signal indicative of an actual tension of the object during a normal operation of the loom, and controlling the rotation of the motor with a feedforward control system during a transient operation of the loom, the feedforward control system storing operation patterns of directions, and speeds of rotation and angular displacement of the motor for respective operation modes and weaving conditions of the loom. At the time of the transient operation, and operating condition of the loom is detected, an appropriate operation pattern is read from the feedforward control system based on the detected operation mode, and the read operation pattern is applied as a control signal to a drive control system for the motor.

    摘要: The optimum control conditions for a plurality of looms are simply estimated with the use of a trial loom. Hereby, the plurality of looms are operated under a centralized control method. The looms, even if they vary in their respective characteristics, can be effectively operated by correcting standard control data for controlling the looms in response to variations of the loom characteristics. The present centralized control method can save much labor and time to improve productivity of the looms, by properly eliminating elaborate trial weaving processes.

    摘要: A control method for a weaving machine comprises the steps of obtaining the rotational frequency to be varied by the use of the fuzzy interference on the basis of the evaluation index representing the running condition level of the weaving machine, and then varying the actual rotational frequency of the weaving machine on the basis of the obtained rotational frequency. As the evaluation index, use is made of the control allowance level of the weaving machine, the quality allowance level of woven fabric, the working allowance level of the operator, the stop level of the weaving machine, the rate of a change value of the stop level to a variation value of the rotational frequency or the operating rate of the weaving machine.

    摘要: A method of controlling an operating speed of the loom for increasing the production rate by varying the present operating speed so as to be increased includes a step of estimating a stop rate at the final point of time during a predetermined period at a certain time during the predetermined period, and comparing the estimated stop rate with a predetermined limit stop rate, and setting the present operating speed to increase it when the estimated stop rate is less than the limit stop rate and to decrease it when the estimated stop rate exceeds the limit stop rate.

    摘要: A warp feed controller for use in a twin beam weaving machine having a first tension detector for detecting the tension of at least one of the groups of warp yarns fed in sheet-like forms from a pair of warp beams and a first control system for controlling the rotation of one of the warp beams on the basis of the tension deviation from a target tension under detection of the tension by the tension detector. The controller also includes a pair of second tension detectors for detecting the tensions of the warp yarns fed from the warp beams in boundary portions of the sheet-like forms, and a second control system for controlling the rotation of the other of the warp beams on the basis of the tension difference output from the second tension detectors, respectively. The first control system controls the one warp beam so that the tension of the warp yarns becomes equal to a target tension, while the second control system controls the other warp beam so that the tensions of warp yarns in the boundary portions become equal to each other.

    摘要: A centralized loom control method employing a host computer for controlling the operation of a plurality of looms. Data base including data accumulated by recording past actual weaving conditions in stored in a memory device connected to the host computer. The host computer determines standard set value for which the looms are to be set by processing the specifications of a fabric to be woven entered therein and data fetched from the memory device through predetermined calculation or interpolation. The host computer compares a standard operating speed among the standard set values with a target operating speed at which the loom is to be operated, and changes the standard set values according to the result of comparison to provide new standard set values suitable for operation at the target operating speed.

    摘要: The present invention relates to a control system for an engagement pin employed in a drum-type weft storage unit which is mainly employed in a jet-loom for storing the weft and for measuring the same in length. A novel control system for an engagment pin employed in a drum-type weft storage unit is provided. An engagement-time is compensated on the basis of a difference in time between a target-time later than the engagement-time of the engagement pin by a normal time-lag, to make it possible that the engagement-time is always set to be optimum in spite of the existanece of variation in shuttling speed of the weft, so that it is possible to keep the variation in length of the delivered weft minimum while the weft feeler is employed in place of the disengagement sensor.

    摘要: A weft picking control method capable of realizing control of a weft picking arriving time with a quick response over a wide range. The weft picking control method in an air-jet loom includes supplying air under pressure to weft picking nozzles, and jetting air under pressure from the weft picking nozzles so as to pick a weft into a warp shed together with the jetted air. Also, a supply passage for supplying the pressurized air to the weft picking nozzles includes high and low pressure supply passages. The passages are arranged in parallel with each other, and the air under pressure is jetted from the weft picking nozzles in cooperation with the two supply passages. A deviation between a weft arrival time of the picked weft and a reference weft arrival time is detected during the weft picking operation, and time for jetting air under high pressure and a weft picking starting time are respectively changed so as to reduce the deviation to zero on the basis of the detected deviation in the next and succeeding weft picking operations.
