Description

[Technical field]
[0001]
  The present invention relates to an optional output programmable electronically controlled sewing machine, and more particularly to a control option output for controlling a plurality of optional devices optionally installed in the sewing machine, not only the operating states of a plurality of operating parts of the sewing machine, but also a plurality of options. This is related to the option output that can be set as an output condition.
[Background art]
[0002]
  Conventionally, in a sewing maker that uses various sewing machines such as industrial main sewing machines and embroidery sewing machines, sewing operations can be performed according to changes in the type and size of the work cloth to be sewn and in accordance with changes in the sewing contents. In order to improve the efficiency of sewing products and improve the quality of sewing products, there is a demand to additionally provide various optional devices. Therefore, when a plurality of optional devices are additionally installed in an industrial sewing machine, various sewing machines have been proposed that can be programmed with optional outputs so that each optional device can be individually operated at an arbitrary timing.
[0003]
  For example, in Japanese Patent Publication No. 6-59351 and Japanese Patent Laid-Open No. 8-280957, control data for outputting an option output for controlling an optional device is stored everywhere in the sewing data for sewing the work cloth. The control data is read during execution of the sewing work, and the option device designated based on the control data is controlled at the desired sewing position so that each option device can be individually operated at any timing. A programmable sewing machine is described.
  Incidentally, as shown in FIG. 16, a sewing machine capable of simple sequence control in which four sequences (sequence 1 to sequence 4) are provided so that each sequence can be started under a separate start condition is also in practical use. .
[0004]
  That is, in each sequence 1-4, four option outputs can be output in sequence, and when the sewing machine returns to the home position, when the start switch is operated, the thread trimming operation and the thread wiping operation are completed. In such a case, the control of each of the sequences 1 to 4 is started with one operation state set out of the operation states of a plurality of basic operation units of the sewing machine as a starting 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, and the option output 1 is triggered by the output of the option output 0. The option output 1 is turned on or off when the start condition is satisfied, and the option output 2 and the option output 3 are sequentially output in the same manner. The other sequences 2 to 4 are the same. By these four sequence controls, a total of 16 types of option outputs (output 0 to output F) can be output.

DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[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, control data for option output for controlling a plurality of option devices is set in the sewing data. Therefore, when sewing data is created and edited according to the number of operations to be performed and the number of optional devices, control data is repeatedly incorporated into multiple locations. There are problems such as complicated creation processing and editing processing, and inability to operate optional equipment when sewing is not executed.
[0007]
  Further, in a sewing machine capable of simple sequence control, the activation condition for activating each sequence is limited to one operation state set from the operation states of a plurality of basic operation units of the sewing machine. When generating optional output that activates the same optional device under multiple activation conditions, the sequence is exclusively used for each activation condition, and the number of remaining sequences is reduced, allowing output to be output. There is a problem that the number of
[0008]
  Furthermore, since the sequence activation conditions are limited to a plurality of basic operations of the sewing machine, the activation conditions are limited, and one generation condition for four option outputs that are output in one sequence is one. Since it is constrained to be set in relation to the previous option output, one option output is linked to the generation of an option output that operates in other sequences, for example, other than the operating state of the operating part of the sewing machine. There is a problem that the condition setting of a generation condition that cannot be generated and is generated by combining a plurality of option outputs is complicated. The object of the present invention is to operate an optional device regardless of whether sewing is in progress,Operating status of multiple operating parts of sewing machine and multiple optional inputsCombining multiple optional outputsNecessary optional outputSimplify the condition setting to set the generation condition to be generatedA programmable electronically controlled sewing machine is provided.
[Means for Solving the Problems]
[0009]
The optional output programmable electronically controlled sewing machine of claim 1 comprises:OhOptional equipment equipped as an option,Control means including a computer for controlling these optional devices and a plurality of sewing actuators;Optional output for controlling each optional deviceOccurrence condition of the control meansIn a programmable electronically controlled sewing machine, a first condition table in which operation states of a plurality of operation parts of the sewing machine are listed and stored in advance, and a plurality of options input from a plurality of optional devices and optional sensors and switches A second condition table that enumerates and stores in advance the operations that enable input on and off, and a third condition table that enumerates and stores in advance the operations that enable and disable multiple option outputs.Is provided in the control means, and is a condition input setting means connected to the control means,By inputting and setting one or more conditions stored in the first to third condition tables,One or moreInput conditions for generating optional output can be set.And a condition input setting means capable of inputting and setting the one or more conditions via a condition setting screen displayed on the display.It is characterized by this.
[0010]
  In the first condition table, the operation states of a plurality of operation parts of the sewing machine such as the presser foot and the thread trimming mechanism are enumerated in advance and stored in the second condition table. Since the established operations are enumerated and stored in advance, and the third condition table enumerates and stores in advance the operations in which a plurality of option outputs are turned on and off.Condition input setting meansByOne or moreAs a generation condition for generating an optional output, one or a plurality of conditions stored in the first to third condition tables are included.Via the condition setting screen of the displayInput is set. That is, the first to third condition tables that list and store the conditions as described above are stored.Control meansCreate it,Need to generate optional outputFor each option output, the first to third condition tableEt 1Or multiple occurrence conditionsFrom condition input setting means to control meansBy simply setting the input, it is possible to reliably and easily operate each of the plurality of optional devices independently of whether or not sewing is in progress.
[0011]
  Furthermore, as the generation condition, not only the operating state of the operating part of the sewing machine but also the setting of ON / OFF of multiple option outputs can be set.option OutputEven when it is generated, the generation condition setting can be simplified.
[0012]
  In other words, when setting the generation condition for generating each option output, you can apply an operation that turns on / off the option output other than that option output, so each option output is linked to the other option output. It can be easily generated.

Yes. The ROM 27 stores a drive control program for driving and controlling the pattern sewing machine 1, a control program for option output control unique to the present application, which will be described later, and a plurality of pattern data for a plurality of pattern patterns with pattern numbers. Yes. In addition, the RAM 28 is provided with a memory for storing sewing data (needle entry data) created at the time of embroidery sewing, and a pointer, a buffer, and the like as necessary.
[0021]
  As shown in FIG. 3, the condition setting operation panel 21 is composed of a microcomputer having a CPU, ROM and RAM, and is provided with a small liquid crystal display 21a and a keyboard 21b composed of numeric keys and various function keys. The needle entry data of the sewing data can be corrected, and various conditions for outputting an option signal OS described later can be set.The condition setting operation panel 21 corresponds to condition setting input means.
[0022]
  In the microcomputer ROM, as shown in FIG. 4 (a), the basic start and end times of a plurality of basic operation units such as a thread cutting mechanism and a presser foot related to the pattern sewing machine 1 are displayed. FIG. 4B to FIG. 4C show a condition table in which the operation states of these operating parts are used as conditions and the operations that satisfy these conditions and the condition numbers are listed and stored in association with each other. Thus, in order to make the condition of the standard operation state of the pattern sewing machine 1 as a condition, there is provided a condition table that enumerates and stores the conditions that satisfy the conditions and the condition numbers, and is described later. A control program for condition data setting control is stored. That is, although not shown in FIG. 2, various detection switches and detection sensors for detecting the establishment of the conditions of the plurality of condition numbers shown in FIGS. It has been.
[0023]
  Further, as shown in FIG. 5, the ROM is an optional equipment that is optionally provided, and includes a plurality of optional signals from a signal output type optional sensor or switch that can output various signals. (Optional input 1 to Optional input 13)as well asThere is provided a condition table that enumerates and stores operations for which OFF is established and condition numbers. Further, as shown in FIG. 6, the ROM is provided on condition that each of a plurality of option outputs (output number “1” to output number “16”) set by the condition setting control is output. Onas well asThere is provided a condition table that enumerates and stores operations for which OFF is established and condition numbers.
  The tables shown in FIGS. 4A to 4C correspond to the first condition table, the table shown in FIG. 5 corresponds to the second condition table, and the table shown in FIG. 6 corresponds to the third condition table. It corresponds to.
[0024]
  Here, in order to make the option output control, which will be described later, easy to understand, the logic of outputting the option signal OS based on the set permission condition, non-permission condition, and output condition will be described based on FIG. Up to three output conditions (output condition 1 to output condition 3) can be set, and up to three permission conditions (permit condition 1 to permit condition 3) can be set to permit the output of option output. Up to three non-permission conditions (non-permission conditions 1 to 3) can be set as the non-permission conditions for limiting the permission conditions, and three permission conditions are input to the OR gate 60. And three further output conditions are input to the OR gate 62. Here, the generation condition includes the output condition, the permission condition, and the non-permission condition.
[0025]
  Then, the output of the OR gate 60 and the output of the OR gate 61 are input to the RS flip-flop (F / F) 63, and the permission signal PS is output from the flip-flop 63. 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 input to the AND gate 64, and the option signal OS is output from the AND gate 64.
[0026]
  That is, when one of the plurality of permission conditions is satisfied, the “H” level permission signal PS is output from the flip-flop 63, but when one of the plurality of non-permission conditions is satisfied, the flip-flop 63 is output. Is inverted, and the “L” level permission signal PS is output. On the other hand, when none of the non-permission conditions is satisfied and the permission signal PS is at “H” level, and any one of the output conditions is satisfied, the option signal OS at “H” level is output.
[0027]
  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, symbol Si (i = 10, 11, 12,...) Indicates each step. On the menu selection screen displayed on the display 21a of the operation panel 21 by the eye contact method, this control is started by selecting the item “output condition setting”. First, the output condition setting screen is displayed on the display 21a ( S10).
[0028]
  For example, as shown in FIG. 11, the first display line includes a mark “OP” for setting an “option number”, an output signal of the option signal OS (“ON”, “OFF”, “F / F (inverted)). "OS" for setting the mark "OS" is highlighted, and the marks "(1) to (3)" for setting up to three output conditions are highlighted on the second display line. The mark “T1” for setting the output waiting time T1 for waiting until the option signal OS is output after the output condition is satisfied, and the mark “T2” for setting the output duration time T2 of the option signal OS are respectively highlighted. Further, keys that can be operated for setting are highlighted in the fourth display line.
[0029]
  Next, a setting process for setting an option number, an output condition, and a set time for timers T1 and T2 is executed based on the display screen (S11), and the setting result is stored in the RAM of the microcomputer when the setting process is completed. It is temporarily stored (S12). For example, as shown in FIG. 13, the set option number and the output condition number are stored in 1 byte with the registration number “1000”, and are set with the registration number “10001”. The output signal type (ON, OFF, F / F) and the set time of the timers 1 and 2 are each stored in 1 byte, and the set times T1 and T2 are set in units of 10 msec.
[0030]
  Next, a permission condition setting screen is displayed on the display 21a (S13). For example, as shown in FIG. 12, the mark “OP” for setting “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. “○” is highlighted, each of the third display line is highlighted with three marks “×” for setting up to three disallowed conditions, and the fourth display line is a key that can be operated for setting. Is highlighted.
[0031]
  Next, a setting process for setting permission conditions and non-permission conditions in addition to the option number is executed (S14), and the setting result is temporarily stored in the RAM of the microcomputer as the setting process ends (S15). This control is terminated and the process returns to the main routine. For example, as shown in FIG. 14, along with the registration number “1002”, the set option number and the three permission condition numbers are stored in one byte for each line, and the registration number “1002” is stored. Along with “1003”, the numbers of the three non-permission conditions are stored in one byte for each line.
[0032]
  Next, an optional output control routine executed by the control device 25 of the pattern sewing machine 1 will be described with reference to the flowchart of FIG. Here, in this control, when the pattern sewing machine 1 is powered on, the condition numbers “1” to “13” and “25” to “25” shown in FIGS. 4A to 4C are used. Whether an operation corresponding to any of “26”, “30” to “38” is established is detected by a subroutine (not shown) or the like, and each time one of the operations is established, the set option number is set. The option output control is executed in accordance with the number, and here, the option output control related to one set option number A will be described.
[0033]
  As described above, this control is started when it is detected by an unillustrated subroutine or the like that an operation corresponding to any of the plurality of condition numbers in FIGS. 4A to 4C is established. First, a condition number corresponding to the basic operation condition of the sewing machine established when the current control is activated is acquired (S20), and output state determination process control (see FIG. 10) is executed for option number A (see FIG. 10). S21). When this control is started, it is first searched whether the condition number corresponding to the established condition is in the permission condition, that is, whether it is set, and if it is not set (S40: No), the condition number is established. It is searched whether or not the condition number corresponding to the condition is set as a non-permission condition. If not set (S42: No), whether or not the condition number corresponding to the established condition is set as an output condition. If it is retrieved and not set (S44: No), the output flag OF is reset ("0" flag data) (S52), this control is terminated, and the process returns to the optional output control S22.
[0034]
  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, in the output state determination process control, when the condition number corresponding to the established condition is set as the permission condition (S40: Yes), the permission flag PF is set (flag data of “1”) (S41). . On the other hand, when the condition number corresponding to the established condition is set as the non-permission condition (S42: Yes), the permission flag PF is reset (flag data of “0”) (S43).
[0035]
  Further, when the condition number corresponding to the established condition is set as the output condition (S44: Yes), and when the output signal is designated "ON" (S45: Yes), the 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 ON or OFF of the current signal (S47: Yes), the output flag OF is set (S48), When the logical product value does not change, the output flag OF is reset (S52). When the output signal is designated “OFF” (S45: No, S49: Yes), the signal flag is reset (S50). Similarly, when the logical product value changes (S47: Yes), the output flag OF. Is set (S48), and when it does not change, the output flag OF is reset (S52).
[0036]
  Further, when the output signal is designated as “F / F” (S45 / S49: No), “inverted” is set as the signal flag. Similarly, when the logical product value changes (S47: Yes), the output flag is set. OF is set (S48), and when it does not change, the output flag OF is reset (S52). That is, even if the permission flag PF is set, if the current signal is “ON” when the current signal is on, or if “OFF” is specified when the current signal is off, The signal OS is not output.
[0037]
  In the option output control, when the output flag OF is set (S22: Yes), the set times T1 and T2 are set for the dedicated on timer A and the off timer A respectively for the option number A (S23). That is, when the output signal is designated “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. On the contrary, when the output signal designates “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”, it is determined according to the signal level at that time whether the set times T1 and T2 are set to the on timer A or the off timer A.
[0038]
  Next, the operation of the reference timer is started (S24), the elapsed time KT of the reference timer does not match the on-timer value HT (S25: No), and the elapsed time KT of the reference timer does not match the off-timer value LT. Sometimes (S31: No), when there is no on-timer or off-timer in operation (S37: No), this control is terminated, but when at least one of these on-timer or off-timer is in operation (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), the option signal OS corresponding to “ON” that matches the on-timer value HT is output (S26).
[0039]
  Next, the presence / absence of an option number on the condition that the option signal OS is turned on is searched. When there is a corresponding option number (S27: Yes), the output state determination process control for the option number N is 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 to the on-timer N and the off-timer N dedicated to the option number N. ), (T2 + α) are set (S30). When there is an operating timer (S37), S25 and subsequent steps are repeatedly executed.
[0040]
  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” coincident with the off timer value LT is output (S32). Next, the presence / absence of an option number on the condition that the output of the option signal OS is turned off is searched. When there is a corresponding option number (S33: Yes), the output state determination process control for the option number M is 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) are set (S36).
[0041]
  When there is a timer in operation (S37), S25 and subsequent steps are executed repeatedly. By the way, when any on-timer or off-timer is not operating (S37: No), this control is output and the process returns to the main routine.
  Next, the operation of the output control of the option signal will be described. For example, a case will be described in which the optional stacker device is operated so that the work cloth subjected to pattern sewing is transported to the side of the pattern sewing machine 1 and sequentially stacked with the end of sewing.
[0042]
  This stacker device is provided with a “cloth presser” that holds the work cloth during conveyance, a “carrying air cylinder”, and an “air valve” that blows air onto the sewing machine table 2 during conveyance. In this case, the material presser, the conveying air cylinder, and the air valve correspond to optional devices, respectively. The option output to be output to each option device is set as follows.
  As for the optional output of <Dough presser>, as shown in FIGS.
-Option number OP: 2-Output signal OS: ON specification-Output condition: Condition number 30-Output standby time T1: 110 msec-Output duration T2: 1200 msec-Permitted condition: Condition number 6-Non-permitted condition: Condition number 81
[0043]
  Regarding optional output of <Air cylinder for conveyance>
-Option number OP: 3-Output signal OS: ON specification-Output condition: Condition number 76-Output standby time T1: 500 msec-Output duration T2: 700 msec-Permit condition: None-Disallow condition: None
  About optional output of <Air valve>
-Option number OP: 4-Output signal OS: ON specification-Output condition: Condition number 76-Output standby time T1: 500 msec-Output duration T2: 1700 msec-Permit condition: None-Disallow condition: None
[0044]
  That is, as shown in FIG. 15, based on the permission condition “6”, the permission flag PF is switched from reset to set at the time t1 when the sewing is finished, and at the time t2 when the presser foot on the pattern sewing machine 1 side is raised. Since the logical product of the permission flag PF and the signal flag changes for the cloth presser output of the option number 2, the output flag OF is set, and from that time t2, only the output waiting time T1 set in the on-timer 2 The cloth presser output is turned on from the time t3 when the output standby time T1 elapses until the time t5 when the output continuation time T2 set in the off timer 2 elapses.
[0045]
  By the way, at the time point t3, that is, when the material presser output is turned on, the logical product of the permission flag PF and the signal flag changes for the air cylinder output for option number 3 and the air valve output for option number 4. From the time t3, the output flag OF is set, so that the output waiting time T1 set in the on-timers 3 and 4 is waited. From the time t4 when the output waiting time T1 has passed, the transfer air cylinder output Is turned on at the time t5 when the output duration T2 set in the off timer 3 elapses, and the air valve output is turned on at the time t6 when the output duration T2 set in the off timer 4 elapses. It is turned on.
[0046]
  By the way, at the time t6, the permission flag PF is reset based on the non-permission condition 6. Here, a programming means is configured by the condition setting operation panel 21 and the condition setting control.
[0047]
  What has been described above is merely an example, and various optional devices that will be equipped in the future in connection with the pattern sewing machine 1 or accompanying the sewing machine 1, for example, an auxiliary pressing mechanism that auxiliaryly presses a work cloth, a pattern sewing machine Optional for a lamp mechanism that lights various color lamps such as “red”, “blue” and “yellow” according to the operating state of 1, such as normal operating state, thread breakage state, emergency stop state, etc. It is possible to control to output option output by setting the output condition, permission condition and non-permission condition for each option output so that the output is output one by one or in conjunction with each other. Yes, the output timing of multiple option outputs can be easily set logically.
[0048]
  In this way, a condition table is provided that lists and stores a plurality of conditions including the operation states of the plurality of operation portions of the pattern sewing machine 1 and the ON / OFF of the option signal OS for the plurality of optional devices. For each option output, simply set the desired one or more output conditions, permission conditions, or non-permission conditions from the condition table, and each of the multiple option devices can be reliably and independently regardless of whether or not sewing is in progress. And it can operate easily.
[0049]
  The generation conditions including the output condition, the permission condition, and the non-permission condition can be set including not only the operation state of the operation unit of the sewing machine but also the ON / OFF of a plurality of option outputs. Even when a plurality of option outputs are generated in combination like numbers 3 and 4, the generation condition setting can be simplified. Further, in the condition setting control, when the generation condition for generating the option output of option numbers 3 and 4 shown in FIG. 15 is input and set, the option output of option number 2 other than the option numbers 3 and 4 is turned on. Since the OFF condition can be applied, the option outputs of option numbers 3 and 4 can be easily generated in conjunction with other option outputs.
[0050]
  In addition, the plurality of conditions in the condition table shown in FIG. 5 include ON / OFF of inputs from a plurality of output type optional devices capable of outputting signals to the outside. By setting, it is possible to link the signal input from the output type option device on / off, or to control the operation of the option device remotely based on the input on / off. .
[0051]
  Here, as a modification of the embodiment, various conditions are set by a personal computer or the like provided in association with the pattern sewing machine 1, and data of the set conditions is stored on a floppy disk or via a connection cord. You may comprise so that it may receive. The contents of the condition table for setting the generation conditions may be configured to 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 embodiments, and within the scope not departing from the technical idea of the present invention, existing controls or controls obvious to those skilled in the art can be used for the control of each part of the above-described embodiments. Various modifications may be made based on the above.
