Then, the printer 5 carries out print wholesale based on various print control signals transmitted from the control unit 90.
- the printing operation on the work cloth W by the printer 5 is performed by moving the cloth holding frame 3 holding the work cloth W in the ⁇ ⁇ ⁇ ⁇ direction by the cloth driving device 4 with respect to the print head 61 displaced to the print position.
- the ink is ejected from the print head 61 in synchronism with the reciprocation one by one, and when one print line (one way) is printed, the cloth holding frame 3 (work cloth W) is moved in the X direction by one. Sending only print lines is to be repeated.
- the ⁇ -direction drive mechanism 30 and the X-direction drive mechanism 45 of the frame drive device 4 use a stepping motor as a drive source as described above, and therefore, each drive motor is used to avoid step-out when switching the rotation direction. It is necessary to secure the acceleration time until the 38, 52 reaches the predetermined rotation speed from the stop state, and the deceleration time until it stops from the predetermined rotation speed.
- each of the drive motors 38 and 52 enters an acceleration / deceleration state in which the speed is not stable between the start of rotation and the stop of rotation. If a print operation is performed in this acceleration / deceleration state, the print will be disturbed. Therefore, the printing of the work cloth W is performed in an area (see a printable area K in FIG. 4) excluding an acceleration / deceleration area (see J in FIG. 4) corresponding to the acceleration / deceleration state.
- the area of the printable area K in the X direction is not reduced.
- the embroidery area N in the Y direction does not change as shown in FIG. [0038]
- the printable area in the X direction (including the embroidery area in this case) of the printable area K does not decrease, but the area in the direction ⁇ is the acceleration / deceleration area at both ends. Will decrease by the amount of
- the ⁇ direction movable distance of the ⁇ direction drive mechanism 30 and the ⁇ ⁇ direction dimension of the cloth holding frame 3 are made larger to correspond to each other, the actual printable area in the ⁇ direction is not reduced. Have been.
- the printing direction is the ⁇ direction (longitudinal direction) and the short direction X is the cloth feeding direction
- the number of times the ⁇ direction driving motor 38 switches the driving direction can be reduced.
- the acceleration / deceleration area as a whole that is, the area where printing cannot be performed among the embroidery areas can be made smaller than when the print direction is set to the X direction.
- the printable area ⁇ ⁇ ⁇ ⁇ for the size of the cloth holding frame 3 is secured to the maximum.
- the reference sign Sc indicates the center of the embroidery area and indicates the embroidery area reference position
- the reference sign Pc indicates the center of the printable area and indicates the printable area reference position.
- the frame driving device 4 When the work cloth W is used for embroidery sewing while driving the frame driving device 4, first, the first positioning concave portion 20h of the cloth holding frame 3 having the work cloth W is engaged with the positioning convex portion 41a of the frame driving device 4 and connected. I do. At this time, as shown in FIGS. 4 and 5, the sewing reference position HPc corresponds to the embroidery area reference position Sc. Thereafter, the frame driving device 4 is driven in synchronization with the vertical movement of the sewing needle 15 driven by the sewing machine motor 93, whereby an embroidery pattern is formed on the work cloth W held by the cloth holding frame 3. As shown in FIG. 4, the embroidery stitches are formed in an embroidery area (see also N in FIG. 4) indicated by a diagonally downward slanted line.
- the print reference position PPc corresponds to the printable area reference position Pc.
- the print is formed in a printable area (see also K in FIG. 4) indicated by a diagonally slanted line falling left and right.
- the acceleration / deceleration area of the Y-direction drive motor 38 composed of a stepping motor is set to the embroidery area inside the cloth holding frame 3 (see FIG. , N) of the printable area in the Y direction in order to print outside the acceleration / deceleration area (that is, not print in the acceleration / deceleration area). Is made longer according to the acceleration / deceleration area. Therefore, it is possible to sufficiently secure a printable area for the cloth holding frame 3 in which the Y dimension of the printable area (X dimension does not decrease because there is no acceleration / deceleration area) is not shortened.
- the print head 61 is configured to have a plurality of nozzle rows 61c to 61f capable of ejecting a plurality of colors of ink. As a result, a plurality of colors can be printed.
- the print head 61 is configured to include a purge mechanism for performing a purge and a cap mechanism for covering the head surface 6 la of the print head 61 with the head cap 80. Therefore, by purging with the purge mechanism, bubbles and dust in the inkjet nozzle 61b can be removed, and drying of the ink can be prevented by the head cap 80 when printing is not performed.
- the sewing machine main body 2 and the printer 5 are provided integrally. This eliminates the work of attaching / detaching the cloth holding frame 3 to / from the sewing machine main body 2 and enables both embroidery sewing and printing while the cloth holding frame 3 is connected to the frame driving device 4. Clearly, the work cloth W is not removed from the cloth holding frame 3 when performing embroidery stitching and printing. The accuracy of the print position with respect to the eyes can also be improved.
- the shape of the cloth holding frame 3 is longer than the direction of the force in the Y direction, but the printer 5 has a configuration in which the printable area of the Y dimension is printed back and forth at a stroke. Therefore, compared to the case of printing in the X direction, the number of times of cloth feeding in which the print head 61 is temporarily stopped in the Y direction and then the cloth is fed in the X direction is reduced, and the print processing time is reduced. it can.
- the printer 5 may be configured to be detachable from the sewing machine main body 2, and may be mounted as needed.
- the printer 5 may be provided with a print data storage memory for storing print data, an embroidery data storage memory for storing embroidery data, and the like, in addition to the control unit.
- the printer 5 is configured to be attachable to the frame driving device 4, and the pre-created embroidery data is transmitted from the printer 5 to the frame driving device 4 and printed on the work cloth W held in the cloth holding frame 3. I'll do it.
- the printer 5 may be for a single color printing in one color such as black or cyan.
- the moving direction of the purge unit 63 can be appropriately adjusted without departing from the gist.
- the embroidery sewing machine with print function of the present invention is effective for a home embroidery sewing machine with a print function added.
