DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronically controlled sewing machine having an option output program, and more particularly, to a control option output for controlling a plurality of optional devices which are optionally provided in the sewing machine, a plurality of operation units of the sewing machine. The present invention relates to a device that can set not only an operation state but also a plurality of optional outputs as output conditions.

[0002]

2. Description of the Related Art Conventionally, a sewing maker sewing using various sewing machines such as an industrial lockstitch sewing machine and an embroidery sewing machine has been required to change the type and size of the work cloth to be sewn and to change the sewing content. Accordingly, there is a demand to additionally provide various optional devices in order to increase the efficiency of sewing work and improve the quality of sewing products.
In view of the above, various sewing machines have been proposed in which an optional output can be programmed so that each optional device can be individually operated at an arbitrary timing when a plurality of optional devices are additionally installed in an industrial sewing machine.

For example, Japanese Patent Publication No. 6-59351 and Japanese Patent Application Laid-Open No. 8-280957 store control data for outputting an optional output for controlling an optional device at various places of sewing data for sewing a work cloth. So that
The control data is read out during execution of the sewing operation, and the specified optional devices are controlled at a desired sewing position based on the control data, so that each optional device can be individually operated at an arbitrary timing. A programmable sewing machine is described. By the way, as shown in FIG. 16, a simple sequence controllable sewing machine in which four sequences (sequence 1 to sequence 4) are provided and each sequence can be started under separate starting conditions has been put to practical use. .

That is, in each of the sequences 1 to 4, four optional outputs can be output in a sequence. When the sewing machine returns to the home position, when the start switch is operated, the thread trimming operation and the thread removing operation are performed. When the operation is completed, for example, the control of each of the sequences 1 to 4 is started on the basis of one set operation state among the basic operation states of the plurality of operation units of the sewing machine as a start condition.

[0005] For example, when the start condition of the sequence 1 is satisfied, the option output 0 is turned on or off when the start condition of the option output 0 is satisfied. When the activation condition of the option output 1 is satisfied, the option output 1 is turned on or off, and thereafter, the option output 2 and the option output 3 are sequentially output. The other sequences 2 to 4 are similar. By these four sequence controls, a total of 16
Various types of optional outputs (output 0 to output F) can be output.

[0006]

As described above, in the programmable sewing machine described in Japanese Patent Publication No. 6-59351 and Japanese Patent Application Laid-Open No. 8-280957, an option output for controlling a plurality of optional devices is provided. Control data is stored at a predetermined position in the sewing data, so that when the sewing data is created and then edited according to the number of times of operation and the number of optional devices, the control data is repeatedly That the process of creating and editing sewing data is complicated, that the optional devices cannot be operated when sewing is not being performed,
There is such a problem.

In a sewing machine capable of simple sequence control, the starting condition for starting each sequence is limited to one set operating state from among a plurality of basic operating states of the sewing machine. From that
When an optional output for operating the same optional device is generated under a plurality of starting conditions, the sequence is occupied for each of the starting conditions, and the number of remaining sequences is reduced, and the number of output options that can be output is reduced. There is a problem that the number decreases.

[0008] Furthermore, since the sequence starting conditions are limited to a plurality of basic operations of the sewing machine, the starting conditions are restricted, and the conditions for generating four optional outputs output in one sequence are as follows. One option output is restricted to be set in relation to the previous option output, so that one option output is used for generating an option output that operates in another sequence other than the operation state of the operation unit of the sewing machine, for example. There is a problem that it cannot be generated in conjunction with each other, and the condition setting of the generation condition for generating a combination of a plurality of option outputs is complicated. SUMMARY OF THE INVENTION An object of the present invention is to make it possible to operate an optional device irrespective of whether sewing is being performed or not, and to simplify the condition setting of an occurrence condition generated by combining a plurality of optional outputs.

In the condition table, not only the operating states of a plurality of operating units of the sewing machine such as a presser foot and a thread trimming mechanism but also a plurality of conditions including ON and OFF of a plurality of optional outputs are listed and stored in advance. Therefore, as a condition for generating each option output by programming means,
One or more conditions stored in the condition table are input and set. That is, a condition table in which a plurality of conditions are listed and stored is created, and for each option output, only one or more desired occurrence conditions are input and set from the condition table to determine whether sewing is being performed. Regardless, each of the plurality of optional devices can be individually and reliably operated easily.

Further, the generation conditions include not only the operation state of the operation section of the sewing machine, but also the turning on of a plurality of optional outputs,
Since the setting including OFF can be performed, even when a plurality of optional outputs are generated in combination, the generation condition setting can be simplified. According to a second aspect of the present invention, in the electronic control sewing machine according to the first aspect, when the programming means inputs and sets a generation condition for generating each option output, it turns on an option output other than the option output. The off condition can be applied.

In this case, when inputting the setting conditions for generating each option output, the ON / OFF condition of the option output other than the option output can be applied, so that each option output is linked with the other option outputs. And can be easily generated. Others
The same operation as the first aspect is achieved. According to a third aspect of the present invention, in the electronic control sewing machine according to the first or second aspect, the plurality of conditions in the condition table include input from a plurality of output-type optional devices capable of outputting signals to the outside. On and off.

In this case, on / off of inputs from a plurality of output-type optional devices included in the condition table, for example, of signals output from an operation panel, various switches, sensors and the like provided in association with the sewing machine. By setting the input as an occurrence condition, it is possible to link the signal input from the output type optional device to ON and OFF, or to remotely operate the optional device based on the input ON and OFF. Can be controlled. In addition, the same operation as the first or second aspect is achieved.

While falling data can be corrected, various conditions for outputting an option signal OS described later can be set.

The ROM of the microcomputer includes:
As shown in FIG. 4 (a), the conditions for starting and ending the operations of a plurality of basic operation units, such as a thread cutting mechanism and a presser foot, and the operation state of the basic operation units for the pattern sewing machine 1 are set as conditions. 4 (b) to 4 (c), a condition table in which operations satisfying these conditions and condition numbers are listed in association with each other and stored as shown in FIGS. 4 (b) to 4 (c). In order to use the condition of the standard operation as a condition, a condition table is provided in which an operation in which the condition is satisfied and a condition number are listed in association with each other, and a control program for condition data setting control described later is provided. Is stored.
That is, although not shown in FIG.
Are provided with various detection switches and detection sensors for detecting the satisfaction of each of the plurality of condition numbers shown in FIGS.

As shown in FIG. 5, the ROM includes a plurality of optional devices, such as signal output type optional sensors and switches capable of outputting various signals. In order to make each of the option signals (option input 1 to option input 13) input as a condition, a condition table is provided which associates an operation satisfying the condition with a condition number.
Further, as shown in FIG. 6, a plurality of optional outputs (output number "1") set by the condition setting control are stored in the ROM.
.., Output condition "16"), there is provided a condition table in which operations satisfying the conditions and condition numbers are listed in association with each other and stored.

Here, in order to make it easier to understand the option output control described later, the logic for outputting the option signal OS based on the set permission condition, non-permission condition and output condition will be described with reference to FIG. . Up to three (output condition 1 to output condition 3) can be set as output conditions, and up to three (permission condition 1 to permission condition 3) can be set as permission conditions for permitting output of the optional output. A maximum of three non-permission conditions (non-permission conditions 1 to 3) are set as non-permission conditions for restricting the permission conditions. Three permission conditions are input to the OR gate 60, and three non-permission conditions are input to the OR gate 61. And three more output conditions are ORed
Input to the gate 62. Here, the condition including the output condition, the permission condition, and the non-permission condition is the occurrence condition.

The output of the OR gate 60 and the output of the OR gate 61 are the RS flip-flop (F / F) 63
And the enable signal P from the flip-flop 63
S is output. Here, when the permission signal PS is at "H" level, the permission flag PF is set.
Further, the permission signal PS and the output of the OR gate 62 are A
The signal is input to the ND gate 64, and the option signal OS is output from the AND gate 64.

That is, when at least one of the plurality of permission conditions is satisfied, the flip-flop 63 outputs the "H" level permission signal PS. The flip-flop 63 is inverted to output the "L" level permission signal PS. On the other hand, when any one of the output conditions is satisfied when the permission signal PS is at the “H” level without any of the non-permission conditions being satisfied, the “H” level option signal OS is output.

Next, a condition setting control routine executed by the microcomputer of the condition setting operation panel 21 will be described with reference to the flowchart of FIG. In the figure, reference symbol Si (i = 10, 11, 12,...)
Indicates each step. This control is started by selecting the item "output condition setting" on the menu selection screen displayed by the eye contact method on the display 21a of the operation panel 21. First, the output condition setting screen is displayed on the display 21a ( S10).

For example, as shown in FIG. 11, a mark "OP" for setting an "option number", an output signal of an option signal OS ("ON", "OFF",
Marks “OS” for setting “F / F (reverse)” are respectively displayed in reverse, and marks “(1) to (3)” for setting up to three output conditions are reversed in the second display line. Is displayed,
In the third display line, after the output condition is satisfied, the option signal O
Mark "T1" for setting output standby time T1 to wait until S is output, output duration T2 of option signal OS
The mark "T2" for setting
In the display line, keys that can be operated for setting are highlighted.

Next, based on the display screen, a setting process for setting an option number, an output condition, and a set time of the timers T1 and T2 is executed (S11). (S12). For example, as shown in FIG. 13, the set option number and the output condition number are each stored in one byte along with the registration number “1000”, and are set together with the registration number “10001”. Output signal type (ON, OFF, F / F), timer 1,
The set times of 2 are each stored in one byte. These set times T1 and T2 are set in units of 10 msec.

Next, the permission condition setting screen is displayed on the display 2.
1a is displayed (S13). For example, as shown in FIG. 12, a mark “OP” for setting an “option number” is highlighted on the first display line, and three marks for setting up to three permission conditions are displayed on the second display line. “O” is displayed in reverse video, three marks “×” for setting up to three non-permission conditions are displayed in reverse on the third display line, and keys operable for setting are displayed in the fourth display line. Is highlighted.

Next, setting processing for setting permission conditions and non-permission conditions in addition to the option number is executed (S14).
With the end of the setting process, the setting result is temporarily stored in the RAM of the microcomputer (S15), this control is ended, and the process returns to the main routine. For example, FIG.
As shown in FIG. 4, the set option number and the numbers of the three permission conditions are stored in a single byte for each line along with the registration number “1002”, and are stored in the registration number “1003”. Accordingly, the numbers of the three non-permission conditions are stored in one byte for each line.

Next, the control device 2 of the pattern sewing machine 1
The option output control routine executed in step 5 will be described with reference to the flowchart of FIG. Here, this control is performed when the power of the pattern sewing machine 1 is turned on, and the condition numbers “1” to “13” and “25” to “25” shown in FIGS. 26 "," 30 "
It is detected by a subroutine or the like not shown whether or not the operation corresponding to any one of to “38” is established, and each time any operation is established, the option corresponding to the number of the set option number is set. The output control is executed respectively. Here, the option output control for one set option number A will be described.

As described above, when it is detected by a subroutine (not shown) that an operation corresponding to any of the plurality of condition numbers shown in FIGS. Is started, first, a condition number corresponding to the condition of the basic operation of the sewing machine established when this control is started is acquired (S20), and the output state determination process control (see FIG. 10) is executed for the option number A. (S2
1). When this control is started, first, it is searched whether or not the condition number corresponding to the satisfied condition is in the permission condition, that is, whether or not the condition number is set. If it is not set (S40: No), the condition is satisfied. It is searched whether or not the condition number corresponding to the condition is set as the non-permission condition. If not set (S42: No), it is further determined whether or not the condition number corresponding to the satisfied condition is set as the output condition. If it is not set (S44: No), the output flag OF is reset (flag data of "0") (S52), this control is terminated, and the process returns to S22 of the optional output control.

Then, in the option output control, since the output flag OF is not set (S22: No), the process returns to the main routine. By the way, when the condition number corresponding to the satisfied condition is set as the permission condition in the output state determination process control (S40: Yes)
), The permission flag PF is set (flag data of "1") (S41). On the other hand, when the condition number corresponding to the satisfied condition is set as the non-permission condition (S
42: Yes), the permission flag PF is reset (flag data of "0") (S43).

Further, when the condition number corresponding to the satisfied condition is set as the output condition (S44: Yes),
When the output signal is designated as "ON" (S45: Yes), a signal flag is set (S46). Then, the logical product of the permission flag PF and the signal flag is obtained, and when the value of the logical product changes with respect to the ON or OFF of the current signal (S47: Yes), the output flag OF is set (S4).
8) When the value of the logical product does not change, the output flag OF
Is reset (S52). When the output signal is "OF"
When "F" is specified (S45: No, S49: Yes), the signal flag is reset (S50). Similarly, when the value of the logical product changes (S47: Yes), the output flag OF is set (S48). If no change is made, the output flag OF is reset (S52).

Further, when the output signal is designated as "F / F" (S45 / S49: No), "inversion" is set as the signal flag, and similarly, when the value of the logical product changes (S45).
47: Yes), the output flag OF is set (S48), and if not changed, the output flag OF is reset (S48).
52). That is, even if the permission flag PF is set, if “ON” is designated when the current signal is on,
If "OFF" is specified when the current signal is off, the option signal OS is not output.

In the option output control, when the output flag OF is set (S22: Yes)
), The set times T1 and T2 are set in the ON timer A and the OFF timer A dedicated to the option number A, respectively (S23). That is, when the output signal is "ON",
The output standby time T1 is set to the ON timer A, and the output continuation time T2 is set to the OFF timer A.
When the output signal is "OFF", the output standby time T1 is set to the off timer A and the output continuation time T2 is set to the on timer A. Further, when the output signal is designated as "F / F", whether to set the set times T1 and T2 to the on-timer A or the off-timer A is determined according to the signal level at that time.

Next, the operation of the reference timer is started (S
24), the elapsed time KT of the reference timer is the on-timer value H
T (S25: No), when the elapsed time KT of the reference timer does not match the off timer value LT (S31: No), and when there is no active on timer or off timer (S37: No). , End this control,
When at least one of these ON timers or OFF timers is operating (S37: Yes), S25 and subsequent steps are repeatedly executed. When the elapsed time KT of the reference timer matches the on-timer value HT (S25: Yes),
An option signal OS corresponding to "ON" corresponding to the ON timer value HT is output (S26).

Next, the presence / absence of an option number conditioned on the ON output of the option signal OS is searched, and if there is a corresponding option number (S27: Yes), the output state determination processing control is performed for the option number N. This is performed as described above (S28). As a result, when the output flag OF is set (S29: Yes), the elapsed time of the current reference timer is set to "α", and the set time (T1 + α) is set for the ON timer N and the OFF timer N dedicated to the option number N. ) And (T2 + α) are set (S
30). When there is an operating timer (S3
7), S25 and subsequent steps are repeatedly executed.

On the other hand, when the elapsed time KT of the reference timer coincides with the off timer value LT (S31: Yes), the option signal OS corresponding to "off" corresponding to the off timer value LT is output (S32). . Next, the presence / absence of an option number conditioned on the off output of the option signal OS is searched, and if there is a corresponding option number (S33: Yes), the output state determination processing control for the option number M is performed as described above. (S34). As a result, when the output flag OF is set (S35: Yes), the elapsed time of the current reference timer is set to "β", and the set time (T1 + β) is set to the ON timer M and the OFF timer M dedicated to the option number M. ),
(T2 + β) is set (S36).

If there is a timer in operation (S37), the steps from S25 are repeated in the same manner. When neither the on-timer nor the off-timer is operating (S37: No), this control is output and the process returns to the main routine. Next, the operation of the option signal output control will be described. For example, a case will be described in which an optionally provided stacker device is operated so that a work cloth on which a pattern is sewn is conveyed to the side of the pattern stitch sewing machine 1 and sequentially stacked upon completion of sewing.

The stacker device includes a “dough presser” for holding a work cloth during transfer, and a “transfer air cylinder”.
And an “air valve” for blowing air onto the sewing machine table 2 during transport. in this case,
Each of the cloth presser, the transfer air cylinder, and the air valve corresponds to optional equipment. The option output to be output to each optional device is set as follows. Fig. 11, Fig. 1
As shown in 2 ・ Option number OP: 2 ・ Output signal OS: ON designation ・
Output condition: condition number 30 / output standby time T1: 110 msec
-Output continuation time T2: 1200 msec-Permission condition: Condition number 6-Non-permission condition: Condition number 81

Regarding the optional output of the <transport air cylinder>: ・ Option number OP: 3 ・ Output signal OS: ON designation ・
Output conditions: condition number 76, output standby time T1: 500 msec
・ Output duration T2: 700msec ・ Permission condition: None
-Non-permission condition: None For <Air valve> option output-Option number OP: 4-Output signal OS: ON designation-
Output conditions: condition number 76, output standby time T1: 500 msec
・ Output duration time T2: 1700msec ・ Permission condition: None
-Non-permission conditions: None

That is, as shown in FIG. 15, the permission flag PF is switched from the reset to the set at the time t1 when the sewing is completed based on the permission condition "6", and the cloth presser of the pattern sewing machine 1 rises. At t2, regarding the output of the cloth presser of option number 2, the permission flag PF
The output flag OF is set because the AND of the signal flag and the signal flag changes, so that the output wait time T1 set in the on-timer 2 is waited from the time t2, and the output wait time T1 has elapsed. Time t5 when the output duration T2 set in the off timer 2 has elapsed from t3
The fabric presser output is turned on over a period of time.

By the way, at the time t3, that is, at the time when the cloth presser output is turned on, the logical product of the permission flag PF and the signal flag is determined for the output of the transport air cylinder of option number 3 and the output of the air valve of option number 4. The output flag OF is set because of the change, so that the apparatus waits for the output standby time T1 set in the ON timers 3 and 4 from the time t3, and starts transporting from the time t4 when the output standby time T1 has elapsed. The air cylinder output is turned on until time t5 when the output duration T2 set in the off timer 3 elapses, and the air valve output elapses the output duration T2 set in the off timer 4. It is turned on over time t6.

By the way, at the time t6, the permission flag PF is reset based on the non-permission condition 6. Here, programming means is constituted by the condition setting operation panel 21 and the condition setting control.

The above description is merely an example, and various optional equipment to be equipped in the future with or in addition to the pattern sewing machine 1, for example, an auxiliary pressing mechanism for auxiliary pressing a work cloth, A lamp mechanism that lights various color lamps such as "red", "blue", and "yellow" according to the operating state of the pattern sewing machine 1, that is, the normal operating state, thread break state, emergency stop state, etc. Controlling the option output by setting the output condition, permission condition, and non-permission condition for each option output so that the option output is output individually or in conjunction with each other and sequentially. It is possible to set the output timings of a plurality of optional outputs logically and easily set them.

As described above, the condition table in which the operation states of the plurality of operation units of the pattern sewing machine 1 and the plurality of conditions including the ON / OFF of the option signal OS for the plurality of optional devices are listed and stored. For each option output, simply set one or more desired output conditions, permission conditions, and non-permission conditions from the condition table, and individually separate each of the plurality of option devices regardless of whether sewing is in progress. It can be operated reliably and easily.

The generation conditions including the output condition, the permission condition, and the non-permission condition can be set not only in the operation state of the operation section of the sewing machine but also in the ON / OFF of a plurality of optional outputs. Even when a plurality of option outputs are generated in combination as in the case of the option numbers 3 and 4 shown, the generation condition setting can be simplified. Further, in the condition setting control, when the generation conditions for generating the option outputs of the option numbers 3 and 4 shown in FIG.
Since the ON / OFF condition of the option output of option number 2 other than the above can be applied, the option outputs of option numbers 3 and 4 can be easily generated in conjunction with the other option outputs.

In addition, since the plurality of conditions in the condition table shown in FIG. 5 include ON and OFF of inputs from a plurality of output-type optional devices capable of outputting signals to the outside, the input of the signals to be output is By setting as an occurrence condition, the signal input from the output type optional device is turned on,
The operation of the optional device can be remotely controlled based on the turning off or on / off of the input.

Here, as a modification of the above embodiment,
Various conditions may be set by a personal computer or the like provided in association with the pattern sewing machine 1, and data of the set conditions may be received by a floppy disk or via a connection cord. Further, the content of the condition table for setting the occurrence condition may be changed or added by the condition setting operation panel 21. Furthermore, the present invention should not be construed as being limited to the above-described embodiment, and existing controls or control obvious to those skilled in the art may be used to control each part of the embodiment without departing from the technical idea of the present invention.
