Abstract:
A driving clutch device for a sewing machine includes a drive shaft, a passive member, a clutch seat, an actuating seat, a power unit, and a clutch member. Through fixing the passive member and the clutch seat onto the drive shaft, rotatably disposing the actuating seat, the drive shaft, and returnably disposing the clutch member to the clutch seat, the clutch seat and the actuating seat are able to move synchronously when the clutch member is in the engaged position, but not to move synchronously when the clutch member in the disengaged position, thereby achieving the driving and clutch controls only by the clutch member, the passive member, the clutch seat and the actuating seat. Therefore, the driving clutch device is simpler and the driving is more direct and instant, thereby reducing assembly costs and the error of action coordination.
Abstract:
The present invention provides a system and method for the application of a functional thread to secure roving or other fibers to a substrate, thereby forming a precursor to a resultant composite component structure having targeted, enhanced structural reinforcement. The functional thread may be comprised of one or more fibrous filaments or have a monofilament structure. The invention encompasses the sewing of this functional thread at varying stitch densities as function of component stress analysis, the mechanical stresses that the component will be subject to when exposed to the forces and loads associated with its intended use, and at least one physical or mechanical property of a functional thread. This variable stitch density serves to provide targeted, localized mechanical enhancement and reinforcement to the resultant composite structure.
Abstract:
A sewing machine includes a sewing machine motor serving as a drive source for driving the vertical movement of a needle bar, a control part for controlling the sewing machine motor such that a sewing pitch coincides with a set value, and imaging part for imaging a seam formed in a workpiece at a needle drop position. The control part obtains the length of the most recent seam from an image of the most recent seam imaged by the imaging part and also compares the length of the most recent seam with the set value of the sewing pitch to thereby correct the number of rotations of the sewing machine motor.
Abstract:
A sewing direction control apparatus for sewing machine, comprising: a base plate (10), a circular ring-shaped transmission element (20) dispose on the base plate (10) and a driving element (50) with a driving unit (52). During sewing, the driving unit (52) drives the transmission element (20), rotating a sewing product (A) placed at the center of the transmission element (20) with the driving element (52), thereby controlling the sewing direction of the sewing product (A), and thus improving the sewing accuracy. The direction control apparatus has low cost, and is suitable for various types of automatic sewing machines.
Abstract:
In a method of wirelessly controlling a sewing machine, a wireless receiver module receives an initial signal transmitted wirelessly and continuously from a speed control module in response to a treading action thereon, and stores a preset security code portion of the received initial signal therein. Thereafter, the wireless receiver module receives an incoming control signal transmitted wirelessly from the speed control module in response to a treading action thereon, and controls operation of a motor unit in accordance with a speed control code portion of the received incoming control signal upon detecting that an identification code portion of the received incoming control signal matches the security code portion stored therein.
Abstract:
Sewing machine being transmitted by one wireless switch or more than one transmitted switches being used to transmit one sewing machine or more than one machine simultaneously used. Sewing machines being ramderley transmitted in various start and stop sewing operations by one individual operator and or a group of individual operators using their allocated sewing machines. A rechargeable battery is used. The speed controller is attached to the machine body. The receiver box supplies the voltage to recharge the battery for the transmitter.
Abstract:
A mouth and/or hand-held finger-actuated remote control unit is disclosed which is operable to permit selective variation of a pneumatic-operated controller (38, 42) having a proportional electrical control output to the electric motor (46) of a sewing machine (48). The unit comprises a hollow, elastic compressible bladder element (10, 110, 210) closed at one end and which is pneumatically connected to the controller. The bladder element is of length, width and height dimensions selected and proportioned to permit insertion of the bladder element in a person's mouth between the upper and lower teeth, or between the last fingers of a person's hand between the innermost knuckles and the person's palm. The bladder element is compressible by closing of a person's teeth thereon or movement of the fingers engaging the bladder toward the individual's palm to force air to the controller, thus controlling operation of the sewing machine. By modulating the pressure applied to bladder element 10 between the person's teeth or the last fingers and the person's palm, the machine may be turned off and on, and the speed of the sewing unit of machine may be controlled within very close limits, and can easily be varied from slow startup to full speed by simply applying more and more bite or finger pressure to the bladder element.
Abstract:
A sewing machine including a head portion including a needle bar, the needle bar being for mounting a needle threaded with a needle thread; a principal shaft; a sewing machine motor for driving the needle bar via the principal shaft; a bed portion including a loop taker for taking a thread loop of the needle thread in cooperative operation with the needle; a loop taker drive shaft connected to move in association with the loop taker; a loop taker drive unit including a loop taker drive motor for driving the loop taker drive shaft independently of the principal shaft; a synchronization control unit for controlling at least one of the loop taker drive motor and the sewing machine drive motor so that the loop taker and the principal shaft rotate in synchronization; and an offset adjustment unit provided to the synchronization control unit and for adjusting an amount that the phase of the loop taker is offset from a reference phase offset amount preset for the loop taker with respect to the principal shaft.
Abstract:
An electronic control system and apparatus is provided for controlling the operation of an industrial machine, such as a sewing machine. A body actuated apparatus is mounted in a spaced apart relationship from ground level and in approximate adjacency to the sewing machine. The body actuated apparatus has an elongated control bar pivotally mounted to the body actuated apparatus along a longitudinal axis of the elongated control bar for actuation of a force sensor when a body of an operator pressingly engages the elongated control bar in a direction towards the sewing machine. Electronic means for controlling the speed of a motor of the sewing machine is provided which includes monitoring means for monitoring sensor input produced by the force sensor, and controlling means responsive to the monitoring means for varying the speed of the motor of the industrial machine by outputting control signals to the motor. Jumper means are provided for programming a particular configuration of input and output requirements responsive to different types of sewing machine motors.
