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:
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.
摘要:
A sewing system including (A) a sewing device which includes (a) a sewing needle, (b) a first driver to reciprocate the needle, (c) a second driver to move the needle and a work sheet relative to each other in a direction crossing an axis line of the needle, and (d) a synchronizer to synchronize the reciprocation of the needle and the relative movement of the needle and work sheet, with each other, so as to form a series of stitches on the work sheet, (B) a detector associated with the sewing device to detect an abnormality of the sewing device, (C) a memory associated with the sewing device and the detector to store operation-state data indicative of an operation state of the sewing device upon detection of the abnormality, and (D) a utilizing device which utilizes the stored operation-state data for a control of the sewing system.
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:
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:
An embroidery data producing apparatus for an embroidery machine which forms embroidery stitches based on embroidery data has the ability to create an embroidery pattern having a uniform thickness without generating overstitched areas. The apparatus includes storage for embroidery data, a selecting mechanism for selecting embroidery data from storage which will generate an overstitched area and a changing mechanism for changing the selected embroidery data into data which will not generate the overstitched area.
摘要:
An embroidery data producing apparatus for an embroidery machine which forms embroidery stitches, based on the embroidery data having information about stitch positions comprises a CPU, RAM and ROM. The RAM has a pattern data memory for storing pattern data which represents outlines of a pattern where embroidery will be given, and a embroidery data memory for storing the made embroidery data. The CPU reads the pattern data stored in an external memory device and stores the pattern data in the pattern data memory. The CPU stores the inclination angle input through the keyboard by an operator in the RAM. The CPU sets a pair of facing outlines which extend to a predetermined embroidery executing direction based on the pattern data stored in the pattern data memory. The CPU sets stitch positions on the first outline of a pair of the outlines according to a predetermined thread density. The CPU calculates the straight line which passes through the set stitch position and inclines at set inclination angle toward the embroidery executing direction. The CPU calculates the intersection where the calculated straight line and the second outline of a pair of the outlines intersect, and sets the intersect as a next stitch position following the set stitch position. The CPU stores the stitch positions set on the first outline and the stitch positions calculated on the second outline as the embroidery data in the embroidery data memory.
