摘要： An apparatus for controlling a let-off motion in a loom having a let-off motion motor includes a tension detector for detecting a warp tension to produce a tension correction signal, a control unit responsive to the tension correction signal for producing a speed signal, a driving amplifier for controlling the let-off motion motor in response to the speed signal, a warp coil diameter detector for issuing a warp coil diameter correction signal inversely proportional to the diameter of a warp coil on a beam to the driving amplifier, and a normal-reverse rotation control unit responsive to the warp coil diameter correction signal for selectively applying prescribed normal- and reverse-rotation signals dependent on a rotation command to the driving amplifier. With this arrangement, the motor is rotated at a desired constant speed for feeding out or rewinding the warp yarn for a desired length irrespectively of the warp coil diameter. In an inching mode of operation, the motor is rotated in a normal or reverse direction for an interval equivalent to one pick each time a main shaft of the loom turns past a certain rotational angle, so that the warp yarn is kept under a desired tension.

摘要： A method of controlling a motor-driven let-off motion in a loom including a system for controlling a let-off motion motor includes the steps of sampling a variation of warp tension during each revolution of a main shaft of the loom, effecting at least proportional and integral control modes on the average of sampled values, adding a proportional and integral output to a basic speed signal at a prescribed ratio, and applying a sum signal to the system for controlling the let-off motion motor. An apparatus for controlling a motor-driven let-off motion in a loom including a system for controlling a let-off motion motor includes an average computing unit for computing the average of warp tension variations detected at a plurality of sampling times while a main shaft of the loom revolves, a control unit for effecting at least a proportional and integral computation on the average to produce a proportional and integral output, a basic speed computing unit responsive to information indicative of the number of RPM of the main shaft of the loom, the diameter of warp coils on beams, and the number of beatings for computing a basic speed, and a speed command computing unit responsive to the proportional and integral output and the basic speed for adding the proportional and integral output to the basic speed at a prescribed ratio to generate a speed command signal and for applying the speed command signal to the system for controlling the let-off motion motor. With this arrangement, there is no time-delay element in the control system and hence any tension variations can be detected quickly. When the loom is stopped in operation, the integral of a warp tension prior to the stoppage of the loom is stored. When the loom is restarted, the stored integral is issued to suppress any unwanted tension variations of the warp yarns. Since a tension compensation gain is not relatively varied when the diameter of a warp coil is changed, the control system can provide ideal control characteristics.

摘要： For ideal stoppage of loom rotation at a constant crank angle, initiation of braking action on loom rotation is always automatically and properly timed on the basis of initial stop lag angle representative of the current braking function so that the resultant actual stop angle should match the preselected stop crank angle and, more preferably, the initial stop lag angle is renewed to cover gradual deterioration in the braking function.

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.
