A multi-needle sewing machine includes a plurality of needle bars, a needle plate, a needle bar case, a needle bar drive mechanism, a needle bar case movement mechanism, a mounting portion, a frame movement mechanism, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include identification processing of identifying a position of the needle bar case in the arrangement direction, in accordance with detection of a retraction command causing the mounting portion to be moved to a retracted position, setting processing of setting the retracted position of the mounting portion on the basis of the identified position of the needle bar case in the arrangement direction, and movement processing of controlling the frame movement mechanism to move the mounting portion to the set retracted position.

A sewing data generating unit acquires embroidery frame information and a mark alignment region displayed on a display unit for guiding multiple marks that define an embroidery region of the embroidery frame. When the marks are all positioned within the mark alignment region displayed on the display unit, the sewing data generating apparatus acquires an image of the embroidery frame and a sewing target mounted on a base cloth mounted on the embroidery frame. The sewing data generating apparatus performs image analysis based on a correspondence between the acquired information with respect to the embroidery frame and the marks in the acquired image, so as to determine the embroidery region of the embroidery frame. The sewing data generating apparatus generates outline data for the sewing target based on the determined embroidery region. This allows an applique to be sewn at an accurate position without a need to prepare dedicated data.

An embroidery frame includes a mounting portion to be mounted on a sewing machine and a frame portion. The frame portion has a first frame, a hinge portion, a second frame, a first clamping portion, and a second clamping portion. The first frame is connected to the mounting portion. The hinge portion is connected to one end of the first frame. The second frame is connected at one end to the hinge portion such that the second frame is able to rotate with respect to the first frame. The first clamping portion is configured to clamp the first sewing object together with the first frame while the second frame is open with respect to the first frame. The second clamping portion is configured to clamp the second sewing object together with the second frame while the second frame is open with respect to the first frame.

A sewing machine includes a sewing portion, a movement portion, a processor and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring pattern data indicating positions of a plurality of needle drop points to sew a pattern, acquiring a position of a sewing start point of the pattern, performing first correction, performing second correction that uses the acquired position of the sewing start point as a base point, and corrects the pattern data, by changing, by an acquired change amount, the positions of the plurality of needle drop points represented by the pattern data corrected by the first correction, and controlling the sewing portion and the movement portion and sewing the pattern on the sewing object, in accordance with the pattern data corrected by the second correction.

The present application provides a three-axis linkage embroidery machine frame and an embroidery machine. The three-axis linkage embroidery machine frame includes a supporting frame, an X-axis driving mechanism, a Y-axis driving mechanism and a Z-axis driving mechanism. The X-axis driving mechanism is arranged on the supporting frame, the Y-axis driving mechanism is respectively coupled with the X-axis driving mechanism and the Z-axis driving mechanism. The advantageous effect of the present application is that, through the linkage of the X-axis driving mechanism, the Y-axis driving mechanism and the Z-axis driving mechanism, not only can the embroidery product be driven to move in the directions of the X-axis and the Y-axis, but also the embroidery product can be driven to rotate 360°, so that it is possible to avoid that the embroidery direction is the same as the thread taking direction of the rotating shuttle when embroidering.
