摘要:
A sewing machine may comprise a needle bar driving mechanism, a cutting needle rotation mechanism, and an embroidery frame movement mechanism configured to move an embroidery frame comprising a protruding portion. A cam member may be fixed to the needle bar and comprise a plurality of cams. A processor of the sewing machine may set a height of the needle bar to a specific position from a plurality of positions. Each of the plurality of positions may represent that each of the plurality of cams is able to contact with the protruding portion. The processor may instruct the needle bar driving mechanism to move the needle bar to the specific position and instruct the embroidery frame movement mechanism to move the embroidery frame to a position where the protruding portion is able to contact with one of the plurality of cams.

A cutting needle rotation device includes a mounting portion, a first member, a moving member, and a rotation mechanism. The mounting portion is removably mounted on a needle bar of a sewing machine. The first member is a member to which a cutting needle is affixed. The moving member is positioned in a first position when the moving member does not receive an external force and moves to a second position when the moving member receives an external force. The rotation mechanism, when the moving member is in the first position, holds the first member such that the cutting needle does not rotate, and when the moving member moves from the first position to the second position and returns from the second position to the first position, rotates the first member such that the cutting needle rotates by a specified angle of rotation in one direction.

In an embroidery sewing machine, a value setting screen on a display indicates parametrical items about the movement of an embroidering frame, i.e., “sewable area” and “stand-by position”, as well as parametrical items about the sewing operation, i.e., “thread-breakage sensitivity” and “number of stitch-back stitches”. An operator enters or designates optimum values for those parametrical items by operating numerical keys and cursor moving keys on a keyboard, and registers a name to be assigned to a set of values for those parametrical items. The set of values for those parametrical items are stored in a floppy disk in relation to the registered name. By simply designating one of the registered names correspondingly to a material to be sewn, the optimum values for the parametrical items are retrieved simultaneously and set for the sewing operation.
摘要:
A control system for a sewing machine, which is operable in a simulation manner as if the control system is connected to the sewing machine. When a sewing-machine control system starts a main control process, a status of its connection to a sewing machine is detected. If the connection is established, a connection flag is set. If it is not established, a connection flag is reset. A display device displays a menu select screen having a list of items, and a desired item is selected from the list. When the selected item is "Sewing process", the sewing-machine control device operates in the following manner. If the sewing-machine control device is not connected to the embroidering sewing machine, a virtual sewing-machine control program is executed to set "in-sewing" data for the pseudo status information, "0" as the initial value for a pseudo number-of-stitches; and "1800" for a pseudo rotation speed signal. The display device displays a pseudo sewing screen, constructed with those items of information.

A controller is disclosed that is communicably connected to a plurality of sewing machines and that includes a display device displaying at least information pertaining to a sewing operation. The controller includes a display controller provided with a queue allocated to each of the plurality of sewing machines and displaying sew pattern data stored in each of the queues to the display device such that the sew pattern data is organized by the sewing machine associated therewith; a specifier specifying one or more sew pattern data from a source queue associated with one of the sewing machines displayed on the display device; a data modifier transferring or copying the one or more sew pattern data specified by the specifier to the destination queue associated with another sewing machine and a data transmitter transmitting the sew pattern data stored in the modified queues to the sewing machines associated therewith.
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.

Provided is an embroidery sewing machine for forming an embroidery pattern in accordance with embroidery data. The embroidery data includes position data indicative of a portion of a working fabric on which the embroidery pattern is to be formed, and color change data indicative of change of needle bars of the sewing machine. The sewing machine is provided with a thread color assigning system which assigns a thread collor to each of the needle bars, an order assigning system which assigns order of the needle bars to be used, a display device which displays the embroidery pattern based on the embroidery data and the order of the needle bars to be used change by the order changing system, and a sewing system which forms the embroidery pattern based on the embroidery data and the order of the needle bars to be used changed by the order changing system.
