摘要： A control apparatus for the embroidery sewing machine which comprises at least two D.C. servomotors for providing controlled power output for driving an embroidery frame, one pair of sensors responsive to rotation of the servomotors for providing detect signals in the form of feedback signals, a presettable counter located at pre-stage to a servomotor drive output amplifier circuit and having an input of the feedback signals in the form of up/down signals, the presettable counter containing a preset value for one stitch operation and counting up or down toward making the preset value zero according to the feedback signal resulting in a residual value if the servomotors are incompletely actuated, and correcting means for superposing the residual value in the counter with a value to be set therein for the next succeeding stitch operation, whereby integral accumulation of errors due to incomplete actuation of each servomotor for each stitch operation can be effectively eliminated. The control apparatus further includes indicator elements which tell the appropriate operation in progress and the completion thereof, and control keys which permit a repetitive operation including a return and an advance, a stop, etc. as required.

摘要： An embroidery sewing machine is provided for automatically driving an embroidery frame along X and Y axes. The bed of the machine is provided with a pair of parallel slots extending parallel to the X axis. A pair of carriages extend through said slots and the opposite ends of a single Y-axis guide rod which extends parallel to the Y-axis are secured to said carriages. A traveller is movably guided along the guide rod and one of said carriages is movably guided along a similar X-axis guide rod mounted below the bed. A pair of servo motors each having a drive roller are disposed under the bed and the carriages and traveller are each provided with a plurality of rollers. Wires extend around the rollers and rotation of one of the servo motors drives the carriages upon which the Y-axis guide rod is mounted along the X-axis guide rod. The rotation of the other servo motor causes the traveller to be driven in the Y-axis direction along the Y-axis guide rod. The embroidery frame is magnetically secured to the traveller for easy detachment. The servo motors operate under the control of a magnetic tape.

摘要： A motor control system for one stitch sewing control of a sewing machine is disclosed. Motor speed is controlled by controlling the trigger phase of motor drive thyristors. Two needle position detectors are employed to detect the arrival of the sewing needle at predetermined halt positions. A pair of motor speed indication signal generator circuits, a pair of memory circuits and a start pulse generator circuit are employed. When the one stitch sewing mode is selected and the foot controller is forced down, the first memory circuit memorizes the start of one stitch sewing and energizes the first motor speed indication signal generator circuit so as to drive the motor of the sewing machine at a predetermined sewing speed. When the first needle position detector detects the arrival of the sewing needle at the lowered halt position, it deenergizes the first memory circuit and the first motor speed indication signal generator circuit, and energizes the second memory circuit for energizing the second motor speed indication signal generator circuit so as to drive the motor at a predetermined lower sewing speed. When the second needle position detector detects the arrival of the sewing needle at the raised halt position, it deenergizes the second memory circuit and the second motor speed indication signal generator circuit. Deenergization of the second memory circuit causes a brake command signal which activates a brake means.

摘要： A sewing machine is provided which automatically drives an embroidery frame in two directions of X- and Y-axes during the time a sewing needle is disengaged from a cloth to be worked. An X-axis drive system and a Y-axis drive system are provided which drive the embroidery frame in the directions of the X- and Y-axes in a conventional manner. The machine includes an electromagnetic clutch mechanism which selectively engages or disengages a needle bar with or from a needle bar drive system in order to permit an increased stroke selectively for which the embroidery frame is driven for each stitch. Additionally, an electronic control system is provided which energizes the electromagnetic clutch mechanism to disengage the needle bar from the needle bar drive system whenever either one of X-axis and Y-axis components of the stroke contained in an embroidery sewing data exceeds a given value, and which deenergizes the clutch mechanism after the termination of driving the embroidery frame and engages the needle bar with the needle bar drive system. If either component of the stroke exceeds the given value, the arm shaft idles to maintain the needle bar at its upper dead center during the time the embroidery frame is being driven. Subsequently, when the drive to the embroidery frame is terminated, a downward movement of the needle bar is allowed.

摘要： A motor control system for a sewing machine is disclosed in which motor drive thyristors, a trigger phase control circuit for the thyristors, a comparator circuit for generating a trigger phase indication signal to accelerate or decelerate the motor to an indicated speed which corresponds to force downward on a foot controller, needle position detector means, a brake command circuit, and a predetermined constant trigger phase command circuit are employed. The predetermined constant trigger phase command circuit, which is energized by a stop signal from the foot controller, supplies a predetermined trigger phase indication signal to the trigger phase control circuit to lower the motor speed. The brake command circuit generates, at the time when the needle position detector means detects the sewing needle at a predetermined halt position, a brake command signal. The brake command signal is supplied to a brake means, e.g., dynamic brake means, mechanical brake means, etc., to stop the sewing needle or thread take-up lever at a predetermined "halt" or stop position. A timer circuit is preferably connected between the foot controller and the predetermined constant trigger phase command circuit to deenergize the predetermined constant trigger phase command circuit and stop the motor after a predetermined time interval. This timing operation of the timer circuit prevents overheating of the motor when the sewing needle stops accidentally before reaching the predetermined halt position.

摘要： A motor control system for sewing a machine is disclosed in which motor drive thyristors, a trigger phase control circuit for the thyristors to control motor speed, and a dynamic brake control circuit means are employed. The dynamic brake control circuit means includes a shunt thyristor connected in parallel with the armature winding of the motor, and a brake command circuit which triggers the shunt thyristor so as to stop the motor by dynamic braking force. The brake command circuit is energized and triggers the shunt thyristor when a stop command signal and a deceleration detection signal are supplied. Thus dynamic braking of the motor of a sewing machine can be accomplished at a predetermined lower speed. To use the motor as a dynamo for dynamic braking stop control of the motor, a trigger phase clamp circuit is employed. To stop the motor at predetermined halt positions, a timer circuit, a predetermined constant trigger phase command signal generator circuit, and needle position detectors are employed. The timer circuit is energized by the stop command signal and generates a signal in a predetermined time interval, by which the generator circuit is energized and controls the trigger phase of motor drive thyristors to decelerate the motor. The brake command circuit triggers the shunt thyristor when motor speed is within a predetermined threshold level and the needle position detectors detect the lowered halt position or the raised halt position of the sewing needle or thread take-up lever.
