Furthermore, it is necessary to take into consideration the ability of the workers, which varies depending on the person doing the work in this regard.

[Problems to be solved by the invention]

The purpose of this invention is to automatically, in a complete way,
Automatically select the operating cycle of the industrial sewing machine in a programmable manner, such that there is no need to divide it into several parts and at the same time any operating cycle can be programmed to ensure product quality; It is an object of the present invention to overcome the above-mentioned drawbacks with respect to regulation and control systems of sewing machine equipment with reasonable procedures currently in use by providing a method for carrying out and an apparatus for carrying out the method.

[Means for solving problems]

To achieve this objective, a programmable device according to the invention automatically selects and executes an operating cycle of an industrial sewing machine, in which the energizing means and associated memory for performing an operating cycle are controlled by a control means. a microprocessor configured to control the computer; a number of option programs for different operations configured to be selected by a selection means are stored in the memory; An option program is programmed to make available a simulation program that can be developed, the selection being such that for each program the display device has all the operating parameters and using a display device connected to said microprocessor to display the selected relevant run value, said control means being configured to vary the run value corresponding to said operating parameter. The present invention is characterized in that a length shift key is provided to obtain a simulation program stored in the memory as a further optional program.

The method of the invention carried out using this apparatus also includes the following steps: (a) the desired program is selected and the microprocessor moves from the needle to the needle before enabling execution of the program from a given point to another point; (b) one selection “PRG” which displays the request for the distance of the rollers and allows the solenoid operated valve to perform the programmed functions in sequence; (b) the first of all sewing lengths to be performed is It is displayed in the form of a numerical code and can be carried out manually or automatically by the control means, in which the value of the supply tension of the rollers in the device is adjusted according to the desired gearing in the garment being sewn. a second selection "Start" in which the preceding supply tension value is automatically supplied to the roller as the value accumulated at the end of the preceding operation; and (c) the identification number of the program is An optional program with a third selection “NR” will be displayed and the number of garments made in the same program within said program, the running time, and the number of garments made during different programs will be displayed. A method for carrying out an operating cycle to be carried out, further comprising a fourth selection "SIM", in which a simulation program is selected which can be developed from a number of previously existing option programs. A new identification indicator is displayed, and a length shift key is placed in a position to change the execution value of the program relative to the previously existing selected program to generate a new simulation program. .

In this way, in this invention, the operating parameters of the selected program can be changed using the length shift key to generate another similar program, so each program can be adjusted to the optimal state in real time. becomes possible.

The features and advantages of the invention will be best understood from the following description of the embodiments, taken in conjunction with the accompanying drawings.

〔Example〕

Referring to the drawings, 1 indicates a microprocessor with memory 2 in the form of E ² PROM or otherwise, and 3 indicates a control panel with keys, not shown, by means of which function and variable parameters and selected subroutines can be accessed. is keyed in. Furthermore, the control panel 3 is equipped with a length shift key for changing operating parameters in the selected program. The liquid crystal display device 4 displays parameters input using these keys.

The key selector 5 selects the following option programs, which will be explained below.

START, SIM Nr By means of the energizing means 6 in the form of an electric valve it is possible to control the sewing machine device 7 in order to carry out the desired operation.

By providing suitable interfaces and biasing means 6, it is also possible to control a plurality of sewing machine devices 7.

The operation of the device according to the invention, as described above and illustrated primarily in terms of structure, will now be described.

First of all, it must be pointed out that the entire process is physically allocated in memory 2, in which the entire control program is generated.

In the program, the following operations related to the optional program described above are performed.

a) switch on the sewing machine and select the desired program setting by key; b) if the "program setting" called PRG is selected, the distance of the needle roller is determined in the form of the number of stitches as a function of the length. c) Given the requested number, the execution of the program from a given point to another (said interval is defined as the "length") determines the particular required program option. d) the determination of the option of said required program is carried out arbitrarily by copying the required program for the requirements in the course from other programs previously accumulated and belonging to other works; e) the program instructions are executed changing some specific parameters (time, function machine) obviously based on the interaction request; f) the energized electric valve is enabled and it g) if after switching on the sewing machine device "Run Program", called START, is selected by the key selector, the display device is activated by the command from the control panel; Indicates the length to be executed (in numerical terms) for which it is possible to select manual or automatic execution; i) it is possible to move to the desired program length using the panel length shift key; l) If automatic execution is determined, then appropriate pre/post or plus/minus values to correct the execution values. A specific subroutine can be selected using the keys; m) If manual execution is decided, the roller is rotated against the screw of the elastic strip in proportion to the last accumulated value; It is possible to vary the supply values of the rollers with respect to the desired gears of the garment to be sewn, n) the sewing machine starts when execution is possible, and o) the predetermined program is activated after the sewing machine has been switched on. Once selected by the selector, said program is determined by its number and the display shows the number of programs, the number of garments to be executed in the same program, the execution time and the length using the shift key, the various programs p) If desired, it is possible to reset the count of clothes and the corresponding time for the execution of a different selector or for resetting the memory; q) after switching on the sewing machine device the SIM If the so-called "Simulation" is selected by the key selector, the number of free programs will be shown on the display, giving the possibility to decide which program to simulate; The length of each stitch will be displayed on the display, the number of stitches and time can be counted using the length shift keys, and the program for each length can be run.
