摘要:
A method and the device for acquiring and processing measurement quantities in a sewing machine (1) using at least one camera (25), situated on a sewing machine (1), for the acquisition and processing of image data for sewing machine elements and sewing elements. An image processing unit connected downstream from the camera (25) processes the images supplied by the camera (25), taking into account data stored in a target quantity memory, and influences the behavior of the machine control unit dependent on the result of the processing.
摘要:
A long arm quilt and lockstitch machine assembly (1) having a framework having two rail tracks, disposed orthogonally on top of one another, wherein the sewing machine (19) is disposed so as to be displaceable on the rail track lying above. The connections between the drive belt (33, 43) to which the rail track (9) lying below and the sewing machine (19) are connected by way of an electronic control system via drive motors, include overload couplings which in the case of overloading by body parts or items of clothing that are caught between the movable elements separate the movable elements from the drive belts. Advantageously, the overload coupling is simultaneously a connection element and in the case of overloading separates the connection between the elements.

A stitcher is provided that includes a needle configured to place stitches in a fabric that is moved therethrough. The stitcher includes a sensor positioned below the fabric to monitor stitches placed in the fabric. A microcontroller is provided configured to receive data from the sensor and, based on such data, to compare one or more attributes of the monitored stitches with one or more predetermined parameters relating at least one attribute of the fabric. The predetermined parameter may be either hardcoded inn the microcontroller or input by a user of the stitcher prior to beginning operation of the machine. When the attributes of the monitored stitches fall outside of the predetermined parameters, the microcontroller initiates notification of the user.
摘要:
A stitching apparatus with thread tension control is provided. Tension in a thread is monitored during stitching apparatus operations, and remedial action is taken in response to the detection of an anomaly in the thread tension profile. The remedial action can include altering a feed rate of the thread in order to adjust the thread tension, and/or repeating a previous operation. Anomaly detection can be performed with respect to stitching or sewing operations, and also with respect to trim operations performed in connection with moving between elements and/or thread color changes.
摘要:
A sewing machine (1) with an overload clutch in the form of a friction clutch in the region of the handwheel (44), with a positioning motor (57), including a motor part (56) and a control part (55), and with a position transmitter (51) connected to the arm shaft (5). In the event of a blockage of the arm shaft (5), the control part (56) causes the positioning motor (57) to stop immediately and a fault warning to be output on an indicator panel (68) of the control apparatus (66). After the fault has been eliminated and the power supply has subsequently switched off and switched on again, the sewing machine (1) is ready for operation again.

Disclosed is a damage detection apparatus for use in a sewing machine including a bobbin having a conductive wire wound thereon, and a sewing mechanism having a metal needle, which sews the conductive wire drawn from the bobbin to an object with thread by means of the metal needle. The damage detection apparatus includes a terminal to be electrically connected to part of the conductive wire, and an indicator electrically connected to both of the terminal and the metal needle and arranged to indicate the occurrence of contact of the metal needle with the conductive wire.

A diagnostic table which stores possible causes of certain abnormal conditions is accessed by corresponding push buttons for sequential vocalization by a sewing machine system, thereby helping the operator check the machine.
摘要:
An electric motor-driven sewing machine which includes a drive mechanism for driving the machine by an electric motor, a mechanism for stopping operation of the machine by a brake, an automatic thread trimmer mechanism, a wiper mechanism for removing the trimmed thread, command switches for providing command signals to the sewing machine and control circuit means for controlling the various operations of the sewing machine in accordance with electrical signals. Apparatus is provided for detecting an abnormal state in which input signals which are not to take place simultaneously occur simultaneously, and to invalidate the operations of the various mechanisms of the sewing machine to protect the user from danger due to erroneous operations of the sewing machine.
摘要:
An automatic sewing machine comprising, a sewing needle, a work holder for moving a work piece relative the needle, and memory means having a plurality of randomly addressable storage locations for retaining data words. The sewing machine has address means for sequentially selecting the storage locations, and means responsive to the data words of the selected storage locations for moving the work holder and performing a sewing operation.
