Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control system for an automatic embroidery machine that can read embroidery data from any position in the middle of the embroidery data and perform an embroidery sewing operation.

[Prior art] In the conventional automatic embroidery machine control system, the embroidery data that forms the basis of embroidery stitching is expressed as relative coordinate data representing the movement order and movement distance of the embroidery frame in X and Y directions. ,
It is not expressed as absolute coordinate data from the beginning of the embroidery pattern. For this reason, when starting embroidery from the middle of an embroidery pattern or returning to the middle to make repairs, conventionally, automatic embroidery machines have been equipped with the embroidery frame's free feed function.
I was locating the desired embroidery data and embroidery frame.

Furthermore, in order to eliminate the need for such a positioning operation, there are some automatic embroidery machines that store relative coordinate X and Y data as absolute coordinate data from the beginning of the embroidery when input from an external input device.

[Problems to be Solved by the Invention] However, in the control system of the conventional automatic embroidery machine configured as described above, in the automatic embroidery machine that uses the jump feed function, embroidery stitches are not performed during the jump feed, but The movement of the embroidery data and the embroidery frame is in one-stitch increments, just like when executing embroidery stitches, so the time required for the free feed function to reach the desired embroidery position is the same as when executing embroidery stitches. Therefore, if you try to start embroidery from 10,000 stitches, it will take about this amount of time.
There was a problem in that people were wasting several minutes of time just for the purpose of doing so. In addition, the worker must monitor the movement of the embroidery hoop and watch the display to see if the desired position has been reached, and the worker is unable to perform other tasks, resulting in a significant decrease in productivity. There was a problem with putting it away. In addition, in the method of storing absolute coordinates, the moving distance as embroidery data is stored as relative coordinate data expressed in 1 by h, whereas when storing absolute coordinates, the moving range of the embroidery frame is expressed. It had to be expressed in 2 bytes. For this reason, there is a problem in that more than twice the required storage memory is required, which increases the cost of the automatic embroidery machine.

The present invention calculates movement coordinates of an embroidery frame that have changed as the embroidery stitch progresses as displacement coordinate data from a reference position by calculating the movement coordinates of the embroidery frame as displacement coordinate data from a reference position. By storing the read address count data and displacement data at the position in pairs with the embroidery data in the embroidery data storage memory, the storage address of the variable coordinate data stored corresponding to the selected embroidery data can be determined. Then, the embroidery frame is moved to the position at which it was displaced at the time of execution of memory writing corresponding to the instruction from the setting operation panel and returned to its original position.

By setting the address count data read out by the reading means in the subsequent embroidery data readout address counter, the embroidery data can be sequentially read out from any position in the middle of the embroidery data.

The object of the present invention is to provide a control method for an automatic embroidery machine that can perform embroidery sewing operations.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides an embroidery data storage means for storing embroidery data for controlling predetermined parts, and a readout address based on the progress of the embroidery operation. In an automatic embroidery machine equipped with an embroidery sewing operation execution means that advances a counter and sequentially reads out embroidery data from the embroidery data storage means and performs embroidery based on the count value of the read address counter, as the embroidery sewing operation progresses, a calculation means for calculating the changed movement coordinates of the embroidery frame as displacement data from a reference position; a position storage means for storing the count value of the read address counter and displacement coordinate data corresponding to the count value; and the position storage means. An instruction input means for instructing execution of writing or reading to the means, and a read instruction from the instruction input means to read out the count value and displacement coordinate data of the read address counter read from the position storage means. reading means, at any position where the embroidery operation is interrupted, according to the displacement coordinate data read by the reading means and the displacement coordinate data at the time of instruction execution in response to the instruction from the instruction input means, The embroidery frame is returned to the displacement position at the time of execution of memory writing, and embroidery data is sequentially read out from the count value of the read address counter read by the read means to perform an embroidery sewing operation.

The reference position may be the position of the embroidery frame at the beginning of the embroidery data, or the position where embroidery is instructed to be performed from the beginning.
This is the position of the embroidery frame at which the automatic embroidery machine starts operating.

Furthermore, the reference position is the position of the embroidery frame designated as the reference position by the instruction input means.

Further, the one-position storage means is capable of storing one or more combinations of the count value of the read counter and the displacement coordinate data for the embroidery data of the workpiece formed by one embroidery pattern.

Furthermore, the storage means is capable of storing different data for each of a plurality of sets of embroidery data.

Also, whether the reading means executes embroidery stitching from among each displacement coordinate data corresponding to a plurality of embroidery data,
Alternatively, displacement coordinate data corresponding to the embroidery data to be executed can be read out.

[Operation] According to the present invention, there is provided an embroidery data storage means for controlling each predetermined part, and embroidery data is sequentially read out from the storage means based on the progress of the embroidery operation, and the embroidery data that has changed as the embroidery sewing action progresses is stored. The moving coordinates of the frame are calculated as displacement coordinate data from the reference position sequentially as the embroidery stitches progress, and read address callan data and displacement coordinate data at any position are stored in the embroidery data storage memory according to instructions from the setting operation panel. By storing the embroidery data in pairs with the embroidery data above, when the embroidery data desired for embroidery is selected, the storage address of the variable coordinate data stored in correspondence with this embroidery data is determined, and further, The embroidery frame is controlled and returned to the position at which it was displaced when memory writing was executed in response to instructions from the setting operation panel.
Further, by setting the address count data by the reading means as the count value of the embroidery data read address counter subsequently read out, the embroidery data is sequentially read from a position in the middle of the embroidery data, and the embroidery sewing operation is performed. be.

There is.

Next, the operation of the control method of the automatic embroidery machine according to one embodiment of the present invention will be explained with reference to the flowcharts shown in FIGS. 2 to 5. First, input multiple embroidery data in advance using an external input device! 11 and a data reading device 12 connected to this external input device 11
The control parameters of these embroidery data are inputted from the setting operation panel 8 and stored in the second RAM 4 for storing the embroidery data.
Furthermore, these embroidery data are backed up and stored by a storage battery.

In this way, when the automatic embroidery machine is turned on as shown in FIG. 2 with embroidery data stored in advance (step 1), the CPU checks whether the circuit section is operating normally. Next, it is checked whether the mechanism is in the normal position based on input from the position detection sensor 29 and position confirmation sensor 35 attached to each mechanism part, and furthermore, the C
The PUI transfers the initial value of the control data from the ROM 2 to the first RAM 3 for work memory, and completes the initialization of the 0 embroidery machine (step 2).

Next, the CPU reads out the storage address of the embroidery data currently in use stored in the first RAM 3 and the control data corresponding to this embroidery data, and calculates the operating status and the like based on these embroidery data and control data. The embroidery data information currently in use is displayed on the display 6 (step 4). Furthermore, in order to obtain the address of the displacement coordinate data storage area in the control parameter area of this embroidery data, predetermined offset data is added to the embroidery data. Add to the first storage address. After completing these series of processes, C
The PUI inputs a switch on the setting operation panel 8 or the operation switch 10 (step 5), and if a switch is operated, the process corresponding to the operated switch is executed. Here, when the reference switch is turned on (step 6), the coordinate data at a predetermined address of the first RAM 3 that stores data for one work is initialized (step 7), and the position of this embroidery frame is set to the reference position. Set as .

Next, when the operation switch is turned on (step 8), C
The PU 1 shifts to operation control processing (step 9). This operation control processing is performed using the first RAM 3 as shown in FIG.
Read and examine the start flag that instructs embroidery stitching from the beginning (step 10). At this time, if the start flag is set, C: PUl uses the address counter that instructs the position to read the embroidery data and the embroidery start flag. The coordinate data that stores the displacement coordinates of the embroidery frame that changes as the embroidery progresses is initialized to O (step 11), and these data are set as the beginning of the embroidery in the primary step.

The CPU calculates the storage address of the embroidery data based on the count value of the embroidery data read address counter, reads out the embroidery data and the control data created in the work area of the first RAM 3, and controls the main axis according to this control data. The motor F is driven to rotate or stopped, and the color changing motor 28 is driven, and the X pulse motor 23 and Y pulse motor are controlled by the embroidery data while timing with the main axis mechanism is determined by inputs from the timing sensor 20 and rotary encoder 19. The embroidery operation is executed by controlling the drive of 25 (Stella 12).

Next, the CPU adds the X and Y embroidery data obtained by driving the X pulse motor 23 and the Y pulse motor 24 and the X and Y coordinate data for which the embroidery has already been sewn.In step 13), the first The data is written to a predetermined memory location in RAM 3. In this way, the calculation is performed for each stitch, and the results are saved and stored, and these data are used as the X and Y coordinate data at the end of the embroidery. Next, the CPU advances the read address counter for reading embroidery data or control data to the next step (step 14), and then checks the embroidery end data or the count number of each counter. Then, it is determined that the embroidery of the embroidery data being embroidered has been completed or interrupted, or it is determined whether the operation switch 10 inputted from the switch input device 9 has been operated to stop.Step 15), the process is stopped. The embroidery stitches are repeatedly executed until it is determined that the switch is turned on. When it is determined that the embroidery is finished or interrupted, the %CPUI returns to step 3 of the main process shown in FIG.

Returning to the main process, in step 3, the CPU 1 again reads out the embroidery data storage address and control data, displays them on the display 6, calculates the displacement coordinate storage address, and activates the switch on the setting operation panel 8 or the operation switch 10. input, and the input switch is checked repeatedly until the switch is operated (step 5).

Here, when the memory switch is turned on (step 16)
The CPUI moves to position storage processing (step 17).
In this position storage process, as shown in FIG. 4, a specified switch on the setting operation panel 8 is input by the operation panel control device 7, and an attempt is made to use the displacement coordinate data and address counter storage area prepared in plurality. The number of the area to be stored is determined (step 18), and the specified input number data is multiplied by the number of data to be used in one area to calculate offset data in the displacement coordinate storage memory.

By adding the first address in the displacement coordinate storage memory to this calculation result, the address to be stored is determined (
Step 19) 0 Next, the CPUI reads the count value of the read address counter of the embroidery data currently indicated for this address and X.

Write the Y coordinate data in a predetermined order (Step 2
0), the process returns to the main process of step 3 in FIG. In this way, when embroidery stitching is interrupted or when the count value and coordinate data of an arbitrary read address counter that has been interrupted due to an operation are input and specified, the number of stored data is specified.

The count value of the read address counter and the coordinate data are separately stored at each of the plurality of embroidery execution intermediate positions.

After returning to step 3 in FIG. 2, the CPU reads out the embroidery data storage address and control data again and displays them on the display 6, calculates the displacement coordinate storage address, and then
switch or the operation switch 10, and repeat checking of the switch until the switch is operated (step 5).

Here, when the return switch is turned on (step 21)
, the CPU moves to position return processing (step 22).
, In this position return process, as shown in FIG.
I input the readout number of the specified switch on the setting operation panel 8 from the operation panel control device 17 (step 23), and determine the number of the area to be used from the storage area of the displacement coordinate data and address counter, which are prepared in plurality. do.

Calculate the offset data in the displacement coordinate storage memory from this specified input number data, and add the start address of the displacement coordinate storage memory to this result to find the address where the data to be restored is stored (step 24) First, the CPUI reads the displacement coordinate data and the count value of the address counter from this address (
Step 25) 6 Next, the current coordinate data set in the first RAM 3 is read out, and by inverting the sign of this, data for returning to the reference position is obtained, and furthermore, data for returning to the reference position is obtained by reading out the data for returning to the reference position. The return movement data to the specified position specified by the number data is calculated by adding the displacement coordinate data (step 26). Based on the X and Y embroidery frame movement data calculated in this way, the CP
The UI outputs the moving direction and moving distance of the embroidery frame to the embroidery frame drive control unit 21, drives the X pulse motor 23 and the Y pulse motor 25, and moves the embroidery frame by the moving distance specified by the embroidery frame movement data. (Step 27) Next, the CPU- transfers the count value of the read address counter for reading out the previously read displacement coordinate data and embroidery data to a predetermined address in the first RAM 3, and transfers the current address count value and coordinates to a predetermined address in the first RAM 3. After setting it as data (step 28), the process returns to the main processing shown in FIG.

In this way, by specifying the number data of the storage area, the count value and coordinate data of an arbitrary address counter that has been stored in advance for the next start position of 5 embroidery stitches can be transferred to the embroidery data of multiple places and the embroidery frame position. It can be reinstated. Then, returning to the main processing shown in FIG. 2, when the operation switch is turned on and the operation is resumed, the CPUI reads out the embroidery data based on the newly set count value of the address counter and executes embroidery sewing.

Note that instead of the X and Y coordinate data, it would be possible to set data that indicates the end of embroidery.

By reading the end count from the embroidery end address counter and setting it in the embroidery end counter, it is possible to end embroidery at any preset embroidery position, making it easy to embroidery using a part of the embroidery data. It can be carried out.

[Effects of the Invention] Since the present invention is configured as described above, it is possible to specify the count value and position coordinate data of an arbitrary address counter when embroidery stitching is interrupted or interrupted by an operation by specifying a storage area number. The count value of the address counter and the coordinate data are stored separately at each execution position of a plurality of embroidery garments, and the storage address is set so that the stored data can be read out in accordance with the selection of the embroidery data. By calculating the embroidery position and inputting instructions on the setting operation panel, the embroidery can be set in advance and returned to the desired embroidery position, and embroidery can be resumed from that position.
By specifying a desired position in the middle of embroidery in advance during sanitization, there is an advantage that embroidery can be performed from the desired embroidery part without having to sequentially read out embroidery data from the beginning of the embroidery.
