Description

Embroidery Machines {EMBROIDERY EQUIPMENT}

The present invention relates to the setting of the embroidery starting position in the embroidery machine and the positioning of the embroidery frame to the embroidery starting position. In particular, the absolute coordinate data of the embroidery starting position desired by the operator is set and input from the operator and stored, and the embroidery The embroidery machine reads the absolute coordinate data of the stored embroidery starting position at the start and moves the embroidery frame to the embroidery starting position corresponding to the absolute coordinate data.

Conventionally, the starting position of the sewing operation of the embroidery pattern in the automatic embroidery machine is set by manually moving the embroidery frame to the desired starting position of the worker using the embroidery machine.

In general, when the embroidery machine starts to sew the embroidery, the current position of the embroidery frame is constantly determined by the relative position at the starting point of the embroidery. Therefore, even if the starting position and the ending position of the embroidery pattern are different, the same embroidery pattern is repeatedly sewn. After the embroidery of the dog pattern is finished, the embroidery frame can be automatically returned to the initial starting position, whereby the same embroidery pattern can be sewn repeatedly.

However, after performing embroidery stitching of a certain embroidery pattern, once it is changed to another pattern to carry out embroidery stitching, and then returns to the original embroidery pattern again to perform embroidery stitching, if the starting positions of the two embroidery patterns are different, the embroidery is embroidered. The frame could not be automatically returned to the beginning of the original embroidery pattern.

In this way, after sewing the embroidery patterns having different starting positions and returning to the original embroidery patterns, the sewing operation is performed again. The starting position of the embroidery patterns is marked on the embroidery frame table at the start of sewing the first embroidery pattern. When the embroidery pattern was once changed and the embroidery pattern was once changed and returned to the original embroidery pattern, the embroidery frame was returned to the start position of the original embroidery pattern by manually moving the embroidery frame up to this mark.

In the conventional embroidery machine as described above, the sewing operation of a separate embroidery pattern (second embroidery pattern) having a different starting position from that during the repeated sewing operation of a certain embroidery pattern (first embroidery pattern) is performed. In this case, the starting position of the first embroidery pattern is marked with a marker or the like on the embroidery frame table, and once the embroidery frame is replaced with the second embroidery pattern, the embroidery frame is returned to the original first embroidery pattern to start the sewing operation. At the time, the embroidery frame was manually moved to the start position corresponding to the mark on the embroidery frame table to set the starting position of the sewing operation of the embroidery pattern. Therefore, there was a problem in terms of work efficiency and a lack of accuracy.

The present invention has been made to solve the above problems, the present invention is to set and store the absolute coordinate data of the embroidery starting position desired by the operator from the operator, and stores the absolute coordinate data of the stored embroidery starting position at the start of embroidery It is an object of the present invention to provide an embroidery machine capable of precisely sewing start positions of each embroidery pattern by moving the embroidery frame to the embroidery start position corresponding to the absolute coordinate data by reading.

Then, the embroidery frame is moved to the desired embroidery start position, and the embroidery starting position absolute coordinate data is displayed by the display means in the embroidery frame absolute coordinate position detecting function to visually check the displayed absolute coordinate data, and then the desired embroidery start is started. The operator sets the absolute coordinate data corresponding to the position by the starting position setting means 50 to be manually stored in the starting position storing means 40.

Thereafter, the absolute coordinate data stored in the starting position storing means 40 is read in correspondence with the embroidery pattern, and the embroidery frame is determined according to the embroidery pattern. The embroidery frame can be moved accurately.

Hereinafter, an embodiment of setting an embroidery start position and allowing an embroidery frame to be positioned at the embroidery start position will be described with reference to FIG. 2, which illustrates an embodiment of a memory map of a RAM. do.

This embodiment manually sets and inputs the absolute coordinate data of the embroidery starting position desired by the operator to store in the starting position storing means 40, and the absolute coordinate of the embroidery starting position in the starting position storing means 40 at the start of embroidery. By reading the data and moving the embroidery frame to the embroidery starting position corresponding to this absolute coordinate data, the embroidery frame can be automatically moved repeatedly to the desired embroidery starting position by the operator.

In this embodiment, the RAM 70 stores the data of the embroidery starting position in addition to the sewing data for executing the embroidery pattern desired by the operator.

The RAM 70 is largely divided into the embroidery pattern data directory 70a and the embroidery pattern data storage unit 70b. Embroidery pattern data storage unit 70b stores embroidery pattern data corresponding to various types of embroidery patterns, and embroider pattern data storage units 1,2 and 3 storing respective embroidery pattern data corresponding to the stored embroidery pattern data. Assuming three stored embroidery pattern data) are generated.

The portion of the embroidery pattern data storage unit 70b in which the embroidery pattern data has not been registered yet is blank.

Embroidery pattern data directory 70a is a portion for storing data indicating stored data (i.e., each embroidery pattern data storage section 1, 2, 3) registered in the embroidery pattern data storage section 70b. to be.

The embroidery pattern data directory 70a has its pattern number and start address for each embroidery pattern data storage unit 1,2,3 registered in the embroidery pattern data storage unit 70b (start address of each storage unit 1,2,3). ) And the end address (the last address of each of the storage sections 1, 2 and 3).

The embroidery pattern number is a number arbitrarily set for each storage unit 1,2 or 3 such as "1", "2", and "3", and identifies registered pattern data. When an arbitrary embroidery pattern number is set by data input at the time of registration, a directory corresponding to the embroidery pattern number is established in the embroidery pattern data directory 70a.

In addition, when an arbitrary embroidery pattern number is designated by data input at the time of reading, the starting address corresponding to the embroidery pattern number is read from the embroidery pattern data directory 70a, thereby responding to the embroidery pattern number. Determination of which one is to be performed is made, and one embroidery pattern data storage unit 1,2,3 (70b) is designated and accessed there.

Each embroidery pattern data storage unit 1,2,3 (70b) is composed of a starting position data storage unit SPME and a sewing data storage unit SME. The sewing data storage unit SME is an area for storing sewing data for realizing embroidery stitches desired by an operator, and conventionally known sewing data (X, Y data and color conversion indicating the position of the embroidery frame, stop of the sewing axis, Data directly related to the embroidery stitching operation, such as possible data indicating each operation of the embroidery sewing machine, such as a jump), are stored for each stitch over the entire stitch of one embroidery pattern.

The starting position data storage unit SPME is an area for storing the absolute coordinate data of the embroidery starting position (hereinafter referred to as starting position data XS and YS. XS is data of X axis coordinate and YS is data of Y axis coordinate). Since the starting position data storage unit SPME is provided for each embroidery pattern data storage unit 1,2,3 (70b), the starting position data is stored for each embroidery pattern, respectively.

3A and 3B are flow charts showing an embodiment of the sewing spindle stop routine, which is shown in FIGS. 3A and 3B for the operation of the part executed by the automatic embroidery machine, in particular the part corresponding to the setting processing of the embroidery starting position. It demonstrates with reference.

When the designated function switch is turned on while the function display for setting the embroidery start position is displayed on the display section of the embroidery machine in the program mode, the "data input setting mode" is selected (80).

If " data input setting mode " is selected, step 80 goes to YES and proceeds to step 81 to read floppy diskette data or to read the embroidery pattern data storage section 70b of RAM 70; Judge.

Whether to read the floppy diskette data or to read the embroidery pattern data storage unit 70b of the RAM 70 depends on the operator's function switch operation in a state in which the display contents of the embroidery unit are switched to the floppy / memory selection mode. Is done by.

When the floppy diskette data is input, first, the process goes to step 82 to set an arbitrary embroidery pattern number and to open a directory corresponding to the embroidery pattern number in the embroidery pattern data directory 70a.

The embroidery pattern number is set by inputting a desired number by the operator by the ten key switch TKY of the input means provided in the embroidery machine. In this case, it is preferable that the display unit displays the embroidery pattern number registered or the embroidery pattern number of which the embroidery pattern data is not registered, and allows the operator to select and set the desired embroidery pattern number among the unregistered embroidery pattern numbers. .

The setting input embroidery pattern number data is stored in the embroidery pattern data directory 70a. At the same time, the start address of the embroidery pattern data storage unit 70b corresponding to the embroidery pattern number is determined by the computer, and the starting address data is stored in the embroidery pattern data directory 70a in correspondence with the storage of the embroidery pattern number data. .

In this way, a start position data storage unit SPME in the embroidery pattern data storage unit (any of 1, 2, 3) 70a corresponding to the set embroidery pattern number is opened, and the start position data XS, YS Initialize the contents to blank.

In the next step 83, it is judged whether or not the floppy start switch is turned on, and when it is turned on, the process proceeds to step 84.

The tape start switch preferably designates one of the function switches or provides a dedicated switch in the input means.

In step 84, the stitch data (X, Y data and function data) for one stitch recorded on the floppy disk is read out, and the RAM 70 for which the stitch data for one stitch is read is indicated by the data memory address DMA. Write to an address within

In the next step 85, the data memory address DMA is advanced by one stitch.

In the next step 86, it is checked whether the content of the function data is the end code indicating the end of the embroidery pattern among the stitch data for one stitch read in the step 84. FIG. If not, the process returns to step 84 and steps 84 to 86 are repeated for the next stitch.

When the stitch data of all stitches is input to the stitch data storage unit SME corresponding to the embroidery pattern number, the function data becomes the end code, and the flow proceeds to step 87.

In step 87, it is determined whether or not the switch instructing the processing for identifying the absolute coordinate position of the embroidery frame is turned on. When performing the process of grasping the absolute position of the embroidery frame, the coordinate acquisition setting switch is turned ON. If the switch is ON, the flow advances to the absolute coordinate positioning subroutine in step 88.

Preferably, the coordinate setting switch may designate one of the function switches or provide a dedicated switch to the input means.

Absolute coordinate positioning process is a process performed by the existing automatic embroidery machine, and FIG. 4 is referred to for explaining the principle.

As shown in Figure 4, the embroidery frame 20 is attached to the fixed embroidery frame table 120, the X-axis origin detection limit switch (SW10) at the origin position of the X-axis and Y-axis of the embroidery frame table 120 And a Y-axis origin detection limit switch SW11 are provided.

In the case where the absolute coordinate positions Xa and Ya of the embroidery frame 20 at any position are to be detected (ascertained), the embroidery frame 20 is moved toward the origin direction so that the embroidery frame 20 has a limit switch ( Stop SW10 and SW11 at the operating position (ie, home position). The amount of movement in the X axis direction and the Y axis direction is counted. This count value indicates the absolute coordinate positions Xa and Ya of the original embroidery frame 20. The embroidery frame 20 once moved to the origin returns to the original positions Xa and Ya.

That is, the amount of movement in the X-axis direction and the Y-axis direction from the current position of the embroidery frame 20 to the origin (X-axis = 0, Y-axis = 0) of the embroidery frame table 120 is determined by the X-axis movement amount counters XA and Y. The calculation is performed using the movement amount counter YA in the axial direction, and the absolute position of the embroidery frame 20 is detected.

Referring to Fig. 5, the absolute coordinate positioning subroutine is performed as follows.

First, in step 89, the XA and XA counters are cleared, and the flow advances to the next step 90.

In step 90, it is checked whether the X-axis origin detection limit switch SW10 shown in Fig. 4 is in the ON state, and if not, the flow proceeds to Step 91.

In step 91, the X-axis pulse motor is moved by one pulse in the negative direction to advance the XA counter, and the flow returns to step 90. Steps 90 and 91 are performed until the embroidery frame 20 reaches the home position in the X-axis direction, that is, until the embroidery frame 20 is detected by the X-axis origin detection limit switch SW10. By repeating, the embroidery frame 20 is moved, and the XA counter advances each time. When the X-axis origin detection limit switch SW10 is turned on by the movement of the embroidery frame 20, the flow advances to the next step 92.

In step 92, it is checked whether or not the Y-axis origin detection limit switch SW11 is turned on. If not, the flow proceeds to step 93.

In step 93, the Y-axis pulse motor is moved for one pulse in the negative direction to advance the YA counter to return to step 92. Steps 92 and 93 are repeated until the embroidery frame 20 reaches the home position in the Y-axis direction, that is, until the embroidery frame 20 is detected by the Y-axis origin detection limit switch SW11. The embroidery frame 20 is repeatedly moved, and the YA counter is advanced each time.

When the Y-axis origin detection limit switch SW11 is turned ON by the movement of the embroidery frame 20, the flow proceeds to step 94. At this time, the count values of the counters XA and YA indicate the absolute positions Xa and Ya of the embroidery frame 20 at the start of this absolute coordinate positioning process.

In step 94, the X-axis pulse motor is moved in the + direction by the count value indicated by the XA counter, and the Y-axis pulse motor 19 is moved by the count value indicated by the YA counter. In other words, the embroidery frame 20 is returned to its original positions Xa and Ya.

In step 95, the count values of the XA and YA counters are displayed on the display unit as data indicating the absolute positions Xa and Ya of the embroidery frame 20. The process then returns to the main routine to perform step 96 of FIG. 4A.

After the absolute coordinate position detecting process is executed, the absolute coordinate of the current position of the embroidery frame 20 can always be determined according to the contents of the counters XA and YA. That is, if the contents of the counters XA and YA are increased or decreased by 1 each time the X-axis and Y-axis pulse motors are driven one pulse in the (±) direction, the contents of the counters XA and YA are always embroidered. You can display the absolute coordinate of the current position of.

Alternatively, the contents of the counters XA and YA are maintained as they are at the end of the absolute coordinate positioning process, and then the relative movement amounts in the X and Y directions of the embroidery frame 20 are counted by different counters, respectively, and the contents of the other counters By adding the contents of the counters XA and YA as necessary, data indicating the absolute coordinates of the current position of the embroidery frame 20 can be obtained.

4A, in step 96, it is checked whether the start position setting switch is turned on. When the start position data is registered, the switch is turned ON and the flow advances to the next step 96.

In step 97, the embroidery pattern number for which the start position data is to be registered is set and input by means of the ten key switch TKY, and the flow advances to the next step 98.

In step 98, it is checked whether the stitching data registration of the set-in embroidery pattern number is completed. If there is an unregistered embroidery pattern number, the flow returns to step 97 to reset the embroidery pattern number. If the registration is completed, the process proceeds to step 99.

In step 99, starting position data XS of the embroidery pattern number in the X-axis direction is input by means of the ten key switch TKY.

In the next step 100 (FIG. 4B), the start position data XS of the pattern in the X-axis direction input in the step 99 is registered in the start position data storage unit SPME, and the flow advances to the next step 101.

In step 101, the start position data YS in the Y-axis direction of the embroidery pattern is input by the ten key switch TKY.

In the next step 102, the input position start data YS of the pattern in the Y-axis direction is registered in the start position data storage section SPME.

In step 103, it is checked whether the data ready switch is already turned on. If it is already ON, the processing proceeds to other processing in the stop routine, and if not yet, the process proceeds to step 104. It is preferable that this data ready switch also designates one of the function switches or provides a dedicated switch in the input means.

In step 104, it is checked whether the data ready switch is turned on. When the setting of the various data is completed, the switch is turned on. If the switch is not turned on, the process returns to step 80. If the switch is turned on, the process proceeds to step 105.

In step 105, the embroidery pattern number to be embroidered is specified.

In the next step 106, the head address of the stitching data storage unit corresponding to the embroidery pattern number designated in the step 105 is set in the data memory address DMA so as to be ready to be read.

In the next step 107, the starting position data XS and YS corresponding to the designated embroidery pattern number are read by the starting position data storage unit SPME.

In step 108, the difference ΔX, ΔY between the absolute coordinate positions Xa, Ya of the current position of the embroidery frame 20 and the starting position data XS, YS read in the previous step 107 is obtained. That is, calculations of DELTA X = XS-Xa and DELTA Y = Ys-Ya are executed.

In the next step 109, pulses are outputted to the X-axis pulse motor and the Y-axis pulse motor by the number corresponding to the differences? X and? Y calculated in step 108, and the embroidery frame ( Move 20). After that, the processing proceeds to other processing.

In the above configuration, when the worker registers the desired embroidery start position, for example, first, the desired embroidery pattern number is set and input, and the embroidery pattern sewing data corresponding thereto is stored in the RAM 70 (steps 82 through ˜82). (86)}. And by moving the embroidery frame 20 by manual or manual switch operation for the embroidery frame is set so that the embroidery frame is located at the desired embroidery start position.

Then, the coordinate setting switch is turned on to execute the absolute coordinate positioning subroutine (FIG. 5). As a result, data of the absolute coordinate positions Xa and Ya of the arbitrarily set position is displayed on the display unit. The operator turns on the start position setting switch after confirming this display (step 96).

Then, the absolute coordinate data of the embroidery start position checked in the display unit is set and input by the ten key switch TKY, and is stored in the starting position data storage unit SPEM as the X axis starting position data XS and Y axis starting position data YS { Step 97-102}.

Before starting the sewing operation, the operator selects the desired embroidery pattern number (step 105), reads the starting position data XS and YS from the starting position data storage unit SPME corresponding to the embroidery pattern number (step 107). }, The embroidery frame 20 is automatically positioned up to its starting positions XS and YS (steps 108 and 109). After that, when the embroidery machine is operated, the embroidery sewing operation is started at the set starting positions XS and YS.

Also, as another method for registering the setting of the desired embroidery starting position, the desired starting position data XS and YS can be arbitrarily selected by the absolute key position (TKY) without performing the absolute position positioning by the absolute coordinate positioning subroutine. May be set appropriately so that it is stored in the start position data storage unit SPME.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention defined in the appended claims.

As described above, according to the present invention, the operator sets and stores the absolute coordinate data of the embroidery starting position desired by the operator corresponding to each embroidery pattern, and stores it in the storage means, and the embroidery starting position in the storage means at the start of embroidery. Since the user can repeatedly position the embroidery at a desired embroidery starting position by reading the absolute coordinate data of the user and moving the embroidery to the embroidery starting position corresponding to the absolute coordinate data, the operator starts the embroidery pattern. There is no need to manually move the embroidery frame until.

In addition, even after performing embroidery stitching of the embroidery pattern, the embroidery embroidery is sewn to another embroidery pattern, and then the embroidery stitch is sewn to the starting position of the embroidery pattern every time even when the embroidery stitch is returned to the original embroidery pattern. In addition to the effect of not having to move the frame individually, the hassle of marking the starting position of each embroidery pattern with a marker on the table of the embroidery frame is also eliminated. It can work.
