Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) In the present invention, when correcting the coordinate position of an embroidery frame, the coordinate position of the embroidery frame is moved using a coordinate input device. The present invention relates to a device for manually moving an embroidery frame.

(Prior Art) Conventionally, in order to move an embroidery frame on XY coordinates, X
2. Description of the Related Art An embroidery sewing machine that automatically controls an embroidery frame driving device provided with a motor for moving in an axial direction and a motor for moving in an Y-axis direction by a computer and performs embroidery sewing is known.

The conventional embroidery sewing machine is provided with a manual operation switch for adjusting the position of the embroidery frame or the like, and the embroidery frame can be moved by manually operating this switch. This manual operation switch is
There were a total of four switches, two switches for instructing forward / reverse of the axial movement motor and two switches for instructing forward / reverse of the Y-axis movement motor.

Further, the conventional embroidery sewing machine is provided with a switch for instructing the moving speed of the embroidery frame (for example, three stages of low, medium and high).

(Problems to be Solved by the Invention) However, in the conventional example, since the manual movement operation of the embroidery frame is performed by operating the plurality of manual operation switches, the embroidery frame is moved in the X-axis direction. And the operation of moving in the Y-axis direction are performed by separate switch operations, and the command switch must also be operated in order to change the moving speed as needed. For this reason, it takes time to move the embroidery frame to a desired position on the coordinates, and the operability is poor.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a coordinate input device that specifies a coordinate position of the embroidery frame on a display screen using a pointing device and inputs the coordinate position to the control device. An embroidery frame movement control means provided in the control device, for controlling an embroidery frame drive motor to move the embroidery frame to a coordinate position corresponding to a change in coordinates input by the coordinate input device. It is characterized by having.

(Operation) According to the present invention, since the coordinate input device specifies the coordinate position of the embroidery frame using the pointing device, a large-scale device for specifying the coordinate position is not required. Further, since the coordinate input device specifies the coordinate position of the embroidery frame on the display screen, the coordinate position can be specified easily and more accurately. Then, the embroidery frame movement control means controls the motor to move the embroidery frame to the designated coordinate position. Thus, the embroidery frame can be moved to a desired coordinate position.

(Embodiment) FIG. 1 is a block diagram showing a configuration of a control system of an embroidery sewing machine provided with an embodiment of an embroidery frame manual moving device according to the present invention.

CPU (operation control device such as microcomputer) 1, program ROM 2, working RAM 3, data shown in FIG.
RAM 4, sewing data memory 5, various interfaces (indicated by I / F in the figure) 6 to 13, etc. (parts unnecessary for the description of the present invention are omitted) are connected via a data bus 27. Thus, a control device of the embroidery sewing machine 28 is configured.

The control device includes an operation panel 14 for inputting various sewing information, a paper tape reader 15 for reading various embroidery information from a paper tape 16, an X-axis motor 18 and a Y-axis motor 19 for moving an embroidery frame 20. Frame motor driver to drive
17, multi-needle sewing machine head 21 color change motor 25, sewing machine spindle 23
, A rotary encoder 24 attached to the sewing machine spindle 23, a switch 26 for instructing start / stop, and a mouse 30 are connected.

In this embodiment, a serial mouse is used as the mouse 30, and horizontal and vertical Mickey values generated from the mouse are input to the control device as coordinate position data in the XY coordinate system.

Next, the operation of the control device during the operation of manually moving the embroidery frame 20 using the mouse 30 will be described. FIG. 2 is a flowchart showing a control routine executed by the CPU 1, and comprises an initial process 41, a stop routine 42, and an operation routine 43. The stop routine 42 is processing when the sewing machine spindle 23 is stopped. In the stop routine 42, manual movement control of the embroidery frame 20 by the mouse 30 is performed. The operation routine 43 is a control process for sewing the embroidery frame on the fabric according to the embroidery data.
By rotating the main shaft 23 of the sewing machine, the X-axis motor 18 and the Y-axis motor
While the embroidery frame 20 is moved by controlling the embroidery frame 19, the set embroidery pattern is automatically sewn.

In the stop routine 42, control is performed according to the flowcharts shown in FIGS.

After performing the initial processing in step 51, step 52
To determine whether the mode is the operation mode or another operation setting mode.
Here, if the operation mode is selected, the data setting process in the operation mode in step 63 is executed. Then, in step 64, the process of turning on the start / stop switch 26 to the start side is performed. Return to In this case, the operation routine 43 is executed next.

On the other hand, if it is determined in step 52 that another operation setting mode has been selected, then in step 53, it is determined whether or not the manual movement operation of the embroidery frame 20 has been selected. If "NO" here, another operation setting is executed in step 62, and the process returns to the main routine.

If step 53 is YES, it is next determined in step 54 whether or not only the X-axis is moved. If YES, the flag of the corresponding mode is turned on in step 60, and if NO, step 55
Move on to Step 55 is to judge whether the movement is only the Y axis,
If YES, turn on the corresponding mode flag in step 61
If NO, in step 56, the flag for temporarily storing that the mode is for moving in both the X and Y axes is turned ON.

Here, a display screen of an embroidery frame moving mode manually is displayed on a display (not shown), and includes a “moving mode only in the X-axis direction”, a “moving mode only in the Y-axis direction”, There is a display for selecting the “movement mode in the XY axis direction”, and a display for selecting any of “enlargement”, “reduction”, and “normal”.

In the “movement mode only in the X-axis direction”, even if the mouse 30 is moved two-dimensionally, information in the vertical direction (Y-axis direction) is ignored, and only the information in the horizontal direction (X-axis direction) is used as the coordinate position. This mode is adopted as data. When it is desired to move the embroidery frame 20 only in the X-axis direction, the embroidery frame 20 is selected on the display screen by the mouse 30. On the other hand, the “movement mode only in the Y-axis direction” is a mode in which only the vertical movement information of the mouse 30 is adopted, and when it is desired to move the embroidery frame 20 only in the Y-axis direction, the mouse 30 Select by.
The “movement mode in the XY axis direction” is a mode in which the movement information of the vertical and horizontal directions is simultaneously adopted by moving the mouse 30, and
This mode is selected when it is desired to move the embroidery frame 20 so as to correspond to the movement of the mouse 30 on a one-to-one basis.

The “enlarge” mode uses the embroidery frame
20 is a mode in which the moving amount is large, and is a mode that is convenient to use when roughly positioning the embroidery frame. The “reduction” mode is a mode in which the moving amount of the embroidery frame 20 is smaller than the moving amount of the mouse 30, and is a mode that is convenient to use when accurate positioning of the embroidery frame 20 is performed. The “normal” mode is a mode in which the amount of movement of the mouse 30 and the amount of movement of the embroidery frame 20 are equal.
The same operation as when the embroidery frame 20 is actually moved by hand can be performed. As described above, since the coordinate position of the embroidery frame 20 to be moved is specified on the display screen, the coordinate position can be easily and more accurately specified.

The case of the “normal” mode will be described more specifically.

When the resolution of the mouse 30 is 254 CPI, the X-axis motor 18
The Y-axis motor 19 has a resolution of 1/1000 rotation. Here, corresponding to the minimum resolution of 0.1 mm of the mouse 30, each of the motors 18 and 19 rotates 1/1000 times.At this time, if the motor shaft and the frame drive system are set to an appropriate pulley ratio,
On the sewing machine table surface, the embroidery frame 20 also exhibits a minimum resolution of 0.1 mm.

The CPU 1 reads the coordinate data from the mouse 30 input from the mouse port interface 6 at an extremely short fixed time interval, and controls the embroidery frame 20 at a speed proportional to the size of the data at that time. Is output to the frame motor driver 17.

For example, if the X-axis side Mickey value input from the mouse port interface 6 is “5” and the Y-axis side Mickey value is “10”, the CPU 1 controls the rotation control signals of the X and Y axis motors 18 and 19. The displacement is 5/10 at the rotation speed of 3 rpm on the X-axis side.
A command of 100 rotations and a displacement of 10/1000 rotations at a rotation speed of 6 rpm is given to the Y axis. Thus, the mouse 30 and the embroidery frame 20 change in real time in one-to-one correspondence with the coordinate position and the moving speed tens.

In the “enlargement” mode, for example, if the rotation control signal is set to 10 times the “normal” mode, the embroidery frame 20 can be moved by 10 times the moving amount and the moving speed of the mouse 30. Conversely, in the “reduction” mode, for example, the rotation control signal is
If it is 1/10 of the “normal” mode, the embroidery frame 20
It will move at 1/10 the moving distance and moving speed of 30.

Therefore, the control for moving the embroidery frame 20 in response to the movement of the mouse 30 as described above is executed by the processing of steps 57 to 76.

In step 57, it is determined whether or not the mouse 30 has been moved, and in step 58, it is determined whether or not a manual movement operation command for the embroidery frame 20 has been input. In the present embodiment, the manual movement operation command is configured to be performed by turning on the switch on the right side of the mouse 30. If these determinations are NO, the process returns to step 53 again. On the other hand, if the mouse 30 has been moved and there is a manual movement operation command, the X and Y coordinate information from the mouse 30 is read in step 59. Then, in step 65 in FIG. 4, it is confirmed which data is in the X-axis direction or the Y-axis direction of the embroidery frame 20 and arranged.

If the mode is to move the embroidery frame 20 only in the X-axis direction,
Through the processing of steps 66 → 67 → 68 → 70, the parameters of the moving direction, the moving speed, and the moving time for moving the embroidery frame 20 in the X-axis direction are determined.
Output to the shaft motor driver.

If the mode is to move the embroidery frame 20 only in the Y-axis direction,
Through the processing of steps 66 → 69 → 70 → 71, the moving direction, moving speed, and moving time parameters for moving the embroidery frame 20 in the Y-axis direction are determined.
Output to the shaft motor driver.

If the mode is for moving the embroidery frame 20 to both the X axis and the Y axis, the processing of steps 66 to 71 is executed, and the parameters indicating the embroidery frame movement information are given to the X axis motor driver and the Y axis motor driver respectively. Is set.

Then, by the processing of steps 72 to 76, control is performed to move the embroidery frame 20 by turning on the motors 18 and 19 for the X axis and the Y axis. At this time, in the mode in which the embroidery frame 20 is moved only in the X-axis direction, only the X-axis motor 18 is turned ON, and
In the mode in which the embroidery frame 20 is moved only in the axial direction, Y
Turn ON only the shaft motor 19. As a result, the embroidery frame 20 moves in response to the movement of the mouse 30.

While the manual movement operation of the embroidery frame 20 is continued, the above processing is repeated at a very short fixed time interval, so that the embroidery frame 20 follows the continuous movement of the mouse 30 on the sewing machine table. Move continuously on.

In the above embodiment, the coordinate input device is
Although an example using the mouse 30 is shown, the present invention is not limited to this, and other pointing devices such as a light pen, a digitizer, a tablet, a joystick, a photo mouse, a trackball, etc. It is also possible to use devices. Many of these pointing devices are small, and their moving range is narrow. In addition, since the pointing device is independent of the embroidery frame 20, a large-scale device using the embroidery frame 20 is not required. Therefore, the coordinate input device for inputting the coordinate position for moving the embroidery frame 20 can be made compact.

In addition, a coordinate position at which the embroidery frame 20 is to be moved (this is referred to as a “target position”) can be input in advance.
By displaying this target position on the display and displaying the coordinate position input from the mouse 30 on the display, it is confirmed whether the coordinate position input by the mouse 30 matches the target position. You may comprise so that it may be possible.

(Effect of the Invention) According to the present invention, the coordinate position of the embroidery frame is specified on the display screen by using the pointing device. Therefore, a large-scale device for designating the coordinate position is not required, and the coordinate position can be simply and more accurately designated.
