摘要:
A sewing device including a head portion for mounting a needle; a support frame; and a bed unit supported on the frame and switchable between a usage position in confrontation with the head portion and a retracted position retracted away from the head portion compared with the usage position.
摘要:
A sewing machine including a head portion for mounting a needle with a needle thread; a needle drive motor for driving the needle; a bed portion; and a loop taker module detachably fixed to the bed portion and including: a loop taker for catching a thread loop of the needle thread of the needle; and a loop taker drive motor for driving the loop taker.
摘要:
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 drive motor for driving the loop taker drive shaft independently of the principal shaft; a first detection unit for detecting a rotation condition of the principal shaft and outputting a first detection signal accordingly; a second detection unit for detecting a rotation condition of the loop taker drive shaft and outputting a second detection signal accordingly; and a synchronization control unit for controlling at least one of the drive motor and the sewing machine motor based on the first detection signal from the first detection unit and the second detection signal from the second detection unit so that the loop taker and the principal shaft rotate in synchronization.

摘要:
A sewing machine including a needle bar for mounting two needles separated by a distance in a principal shaft direction; a principal drive shaft for driving the needle bar and extending in the principal shaft direction; a bed portion; a first loop taker disposed in the bed portion; a transmission system for connecting movement between the first loop taker and the principal drive shaft; a loop taker module detachably provided to the bed portion; a second loop taker provided to the loop taker module; and servomotor provided in the loop taker module and for driving the second loop taker.
摘要:
A sewing system includes a first automatic sewing machine and at least one second automatic sewing machine. The first automatic sewing machine includes a RAM for storing stitch data. The stitch data is processed into data for primarily controlling a needle position, and the data thus processed is stored in the RAM. The first automatic sewing machine further includes a data transmitting device for outputting the processed stitch data to the outside of the sewing machine. The second automatic sewing machine includes a data receiving device for receiving the processed stitch data from the data transmitting device in the first automatic sewing machine. When receiving the processed stitch data from the data transmitting device in the first automatic sewing machine, the second automatic sewing machine starts sewing according to the processed stitch data thus received.
摘要:
A sewing machine capable of tracing an embroidery area by relatively moving a needle bar as a sewing device and an embroidery frame which holds a work cloth on which an embroidery pattern is embroidered based on embroidery data, comprises a calculating device that calculates a convex polygon in multiples of eight covering the pattern inside from the embroidery data, and positions of a plurality of vertexes comprised of the convex polygon, and a trace device that traces the embroidery area based on the vertexes found by the calculating device.
摘要:
An operation data processing device that summarizes trouble situations that occur during sewing operations. A log data storing device generates and stores log data based on an operation state of pattern sewing machines. A trouble summarizing device summarizes trouble information that occurs during operations. The trouble information is then summarized in association with a stitch number based on the stored log data. A displaying device visualizes the trouble information in a manner that allows a user to easily determine a trouble location and frequency for a given sewing pattern.
摘要:
A lot sewing time required for sewing a lot of embroidery patterns is calculated based on data of the embroidery pattern to be sewn and on data indicating the number of times the embroidery pattern is to be sewn in the lot. After data for the calculated lot sewing time is received, the lot is allotted to one of a plurality of sewing machines. The lot time for each of a plurality of lots allotted to the plurality of sewing machines is displayed on a display.
摘要:
Disclosed is a data processing device for processing data representing an operation status of a pattern sewing system which includes at least one pattern sewing machine alternately operated by a plurality of operator groups. The data processing device may include a time zone setting device which sets a plurality of time zones. A plurality of operator groups operate the pattern sewing machine during a plurality of time zones, respectively. There is provided a log data recording device which records an operation status of the pattern sewing machine as log data, and an operation data creating device which creates operation data representing a predetermined operation parameter for each of a plurality of operator groups based on a plurality of time zones set by the time zone setting device and the log data recorded by the log data recording device.
