The yes Panic Patent Applications No. 63-21 951 (1988) and No. 63- 21 953 (1988) describe a method for regulating the Main drive, warp lowering device, fabric Drive, etc. of a loom based on the Target conditions for a fabric to be woven, such as Art of the yarn, weaving width, weaving density, type of weave, etc. I.e. that a number of rule data for the web conditions entered in the control system of the weaving machine at the beginning and the regulation will automatically be a suitable one  Set of control data for a fabric to be woven. On this way you can quickly find the optimal web data in the scheme is entered without having to click on the Skills and operator experience must face.

One of the objects the invention is intended to accomplish is described below. Any setting value for a be correct tissue corresponds to a certain value of a re gel size, which is usually based on the experience of Past are determined. But it may be necessary that some of the selected web data are changed should to improve the web conditions. To this The purpose is a weaving machine that uses control data from the Re Gelcomputer is operated with a data entry device device for entering and setting the new control data and provided for changing the existing control data. But with entering this new data there is a risk that the existing control data due to incorrect operation of the Input device replaced by incorrect data or over be written.

Therefore, it is an object of the present invention to provide a To create procedures that require entering incorrect rules prevent in the weaving machine regulation by a external storage medium, such as a memory card ver is used, which advantageously to regulate an number of weaving machines can be used as this in the Japanese Patent Application No. 1-2 80 050 (1989) is.

In order to achieve the above-mentioned goal, Invention invention a method for regulating the weaving of Loom which is equipped with a control computer, which contains control data, according to which the weaving of the weaving machine machine is regulated and with an input device for Enter the control data in the control computer and with a  Function for transferring data between the control computer ter and an external storage medium, the new cry ben of the control data prevented with the input device when the data connection between the control computer and the external storage medium is interrupted.

If the control computer and the external storage medium are not are in an electrically connected state, an off output signal by operating the input device is suppressed and therefore the reappearance write is not executed by the control computer. If the control computer and the external storage medium which are electrically connected becomes the above output signal effective, the rewriting with data becomes possible.

The aim of the invention is also to prevent the erroneous change of control data in a weaving machine. The main control computers Ce, Cg are connected via serial lines L to the auxiliary computers Cs, Cr, Cd, Cy for controlling the drive systems of certain devices of the weaving machine, so that the control data from the main control computers Ce, Cg to the respective control computers Cs, Cr, Cd, Cy are transmitted via these serial lines L and the transmission units Fm, Fs, Fd, Fy.

The reference numeral M in Fig. 1 denotes a weaving machine NEN drive motor, the function of which are controlled by the main Regelcom puters Ce and Cg, each of which is assigned to a group of looms, a drive motor M independent of the loom drive motor, is used with designated by the reference numeral 1 . The warp let-off motor 1 drives a warp beam 2 , from which the warp threads T are unwound. The unwound warp threads T are guided over a wiping roller 3 and a tension roller 4 to the healds 5 and a reed 6 . The fabric W is a tensioning tree 7 , a take-off roller 8 and a pressure roller 9 out to be wound on a fabric tree 10 . The tensioning roller 4 is at one end of a tensioning lever 11 BEFE, which has at its other end a spring 12 which acts on the tensioning roller 4 so that it is connected to the Kettfä the T and thereby exerts a tensile force on this. The clamping lever 11 is supported on one end of a Füh lerhebels 13 which is connected at its other end to a force sensor 14 . In such an arrangement, the warp tension is transmitted via the tensioning roller 4 , the tensioning lever 11 and the feeler lever 13 to the force sensor 14 , which leads to the force sensor 14 generating a signal which corresponds to the size of the warp tension which is applied to the tensioning roller 4 acts, is characteristic, and which is fed to the Kettablass computer Cs.

The Kettablaß computer Cs controls the speed of rotation of the Kettablaß motor 1 by comparing the effective Kettspan voltage, for which the electrical output signal of the Kraftsen sensor 14 is characteristic, with a warp tension target value. The warp tension is precisely adjusted by regulating the speed of rotation of the motor 1 . At which the warp let-off computer Cs provides on the basis of the signals of a rotary knife 1 a, which is installed in the warp let-off motor 1, a control for the rotational speed of the warp let-off motor. 1

The goods take-off roller 8 is gekop pelt to a winding motor 15 , which is also independent of the main motor M. The rotational speed of the motor 15 is controlled with a winding control computer Cr, on the basis of the output signals of a rotary knife 15 a, which is installed in the winding motor 15 .

A weft insertion nozzle 16 pulls the weft from a drum weft store 17 and carries it with an air jet that emerges from the nozzle 16 into the open weaving compartment. A spool-operated valve 18 controls the compressed air flow of the entry nozzle 16 and is controlled by a shot measuring computer Cd.

The main control computers Ce, Cg, the warp let-off computer Cr, the weft measurement computer Cd and the weft insertion computer Cy have transmission units Fm, Fs, Fr, Fd and Fy, respectively. These transmission units Fm, Fs, Fr, Fd and Fy are connected in series with the transmission lines L, as shown in FIG. 1. Each of the control computers Ce, Cg, Cs, Cr, Cd, Cy is connected to a rotary knife 19 for determining the angle of rotation of the weaving machine in order to obtain an output signal therefrom which is representative of the angle of rotation of the weaving machine. The control computers Ce, Cg, Cs, Cr, Cd, Cy regulate on the basis of the angle of rotation position of the weaving machine, which is output by the rotary knife 19 , and the main computers Ce, Cg also regulate the transmission of control data to the respective auxiliary control computers Cs , Cr, Cd, Cy via the serial transmission lines L.

As shown in Fig. 1, the main control computers Ce, Cg are connected to the input units 20 e and 20 g, respectively. Each of these water input units 20 e, 20 g has a slot 20 e, 20 g for receiving a memory card 26 , 26 A. The memory card 26 , 26 A can be electrically connected to the main computers Ce, Cg if they are in the slot 20 a is introduced.

In Fig. 2, each of the symbols Le, Lg (e = 1, 2, 3, etc .; g = 1, 2, 3, etc., where e is not equal to g) represents a group of weaving machines and it is indicated that each group of Weaving machines is regulated by their assigned main control computer Ce or Cg. Each of the input units 20 e, 20 g shown in FIG. 1 includes a transmission data selection unit 21 , a transmission control unit 22 , a data rewrite unit 23 , a display unit 24 and a comparator unit 25 as shown in FIG. 2.

The transfer control unit 22 is used to select the direction of the data transfer, ie either the transfer from the main control computer Ce, Cg to the memory card 26 '26 A or vice versa. The main control computer Ce has a memory Me which receives a series of current weaving data E which are representative of the current warp beam diameter, a warp thread break, if there is one, a missed shot, if there is one, etc . These data are determined using suitable detectors. In the memory Me are warp let-off data and fabric tree data A, including the control data for the warp tension, the warp let-off speed, the goods winding speed, etc. ge stores; a series of shot measurement data B, including the control data for the shot length, the start time for the weft insertion, the end time for the weft insertion, etc .; a series of weft insertion data c including the control data for the blowing start of the weft injection nozzle, the blowing end, etc .; a series of rotation angle data D, including the control data of the win kellage of the main shaft of the weaving machine, in which the weaving machine starts or stops. These data series A, B, C, D can be entered into the memory Me with the aid of the data rewriting unit 23 .

As shown in Fig. 3, the series of the warp let-off and fabric wrap data is A, which is A (1), A (2). . . A (i) comprises, in the addresses n ₁ , n ₂ ,. . . or n _i stored; is the series of the shot measurement data B, which from the data B (1), B (2). . . or B (i), is stored in the addresses n _{i + 1} , n _{i + 2} ... or n _{i + j} : the series of shot entry data C, which consists of the data C (1), C ( 2). . . or C (k), addresses n _{i + j + 1} , n _{i + j + 2} . . . or n _{i + j + k} saved; and the series of rotation angle data D (1), D (2). . . or D (p) is in the addresses n _{i + j + k + 1} , n _{i + j + k + 2} . . . or n _{i + j + k + p} saved. The series of web data E is stored in addresses other than those mentioned above.

In the same way, in the memory Mg of the main rule computer Cg of the weaving machines Lg there are a series of warp let-off and fabric-winding data A ', which from the respective data a (1), a (2). . . a (i) exists, stored in the addresses n ₁ , n ₂ ... or n _i ; a series of shot measurement data B 'which from the respective data b (1), b (2). . . or b (j), the addresses n _{i + 1} , n _{i + 2} . . . or n _{i + j} ge stores; a series of weft entry data C ', which the respective data c (1), c (2). . . or c (k) is included in the addresses n _{i + j + 1} , n _{i + j + 2} . . . or n _{i + j + k} stored and a series of rotation angle data D 'which from the data d (1), d (2). . . or d (p), the addresses n _{i + j + k + 1} , n _{i + j + k + 2} . . . or n _{i + j + k + p} t stored and a series of running web data E 'is stored in addresses other than those mentioned above.

Assuming that the weaving machines Le and Lg weave the same article, but the weaving machines Lg run with a remarkably low efficiency while the weaving machines Le are operating normally, it can be assumed that the series of data A ′, B ′, C ′, D 'in the memory Mg do not match the corresponding data series A, B, C, D, E in the memory Me of the weaving machines Le. In other words, it can be assumed that the rows of correct data A, B, C, D are not used for the regulation of the weaving machines Lg. The memory card 26 A is used to check whether the rows of data A ', B', C ', D' match those of the rows A, B, C, D or not.

First, the storable 26 A is inserted into the card slot 20 a of the input unit 20 e of the main control computer Ce of the normally operating weaving machines Le. If the memory card 26 A is correctly inserted, the main control computer responds to a memory card insertion signal and is accordingly brought into readiness for the data transfer. Then, when the data transfer control unit 22 instructs the data transfer select unit to transfer selected data, the main control computer Ce is caused to select the selected data series A, B, C, D from its memory Me to the bare 26 A transferred to. During this data transfer, the warp let-off and fabric-winding data A (1), A (2) A (i) in the memory Me of the main control computer Ce into the addresses m ₁ , m ₂ ,. . . copied m _{1 of} the memory card. Then the shot measurement data B (1), B (2). . . B (j) into the addresses m _{i + 1} , m _{i + 2} . . . m _{i + j} copied; the weft entry data C (1), C (2). . . C (k) into the addresses m _{i + j + 1} , m _{i + j + 2} ... m _{i + j + k} or the rotation angle data D (1), D (2). . . D (p) into the addresses m _{i + j + k + 1} , m _{i + j + k + 2} . . . m _{i + j + k + p of} the memory card 26 A copied.

Then the memory card 26 A, which has stored the control data for the weaving machines Le, is inserted into the card slot 20 a of the input unit 20 g of the main control computer Cg of the weaving machines Lg. After the insertion of the memory card 26 A, the data comparison unit 25 causes the main control computer Cg to store the data A (i), B (j), C (k), D (p) in the memory card 26 A with the data a (i), b (j), c (k), d (p) in the memory Cg of the main control computer Cg. This comparison can be serial, one after the other, address after address between the corresponding pairs of data in the addresses m ₁ , m ₂ to n _{i + j + k + p of} the memory card 26 A and the data in the addresses n ₁ , n ₂ , to n _{i + j + k + p} in the memory Cg, take place; and the data that do not match the corresponding data in the memory card 26 A are displayed on the display unit 24 . For example, if the data b (2) in the addresses m _{i + 2} in the memory Ce do not match the data B (2) in the address n _{i + 2} in the memory Cg, the main control computer Cg causes the data of the Show addresses n _{i + 2} and their data b (2) on the display unit.

The data on the display unit 24 in this way can be regarded as the data which cause the abnormally low efficiency of the weaving machines Lg. By overwriting the data, ie the data b (2), which are displayed on the display unit in the example above, via the data B (2), with the aid of the data overwrite unit 23 , the incorrect data can be changed in this way that they coincide with those of the weaving machines Le and so the abnormal weaving of the weaving machines Lg can be corrected.

As shown in FIG. 3, the memory card 26 A contains the overwrite approval program Xo and a program Yo is loaded into the main rule computer Ce, Cg, which decides whether the data overwrite should be carried out or not. The main control computers Ce, Cg perform data overwriting according to the program illustrated in the flowchart of FIG. 4.

That is, if the memory card 26 A is not in place in the input unit 20 g of the main control computer Cg, the main control computer Cg is in the non-write mode and a write command is suppressed even if an overwrite command is given with the input unit. If the memory card is correctly inserted into the input unit, the main control computer responds to a memory card insert signal and then receives the overwrite enable, and then reads the overwrite program Xo into the memory card 26 A. Accordingly, the The main control computer Cg is put into the overwrite mode and the overwriting of only those data which are determined by the overwrite approval program Xo is carried out. In the example described above, overwriting of data b (2) is permitted and therefore only overwriting of this data 3 (2) into address n _{i + 2 can} take place. In this way, erroneous overwriting with the input Unit 20 g can be prevented.

Otherwise, the data series A, B, C, D, E in the memory Me of the main control computer Ce and die Enter the data series A ', B', C ', D', E 'into the memory Mg of the other main control computer Cg with the help of a memory card which contains an overwrite approval program Xo contains, which allows the transfer of all data.

It should be noted that the present invention not limited to the embodiment described above should be, but it can also be in various other Forms are exercised. E.g. can the release to data Overwrite only due to a card insertion signal  done, which is generated when the memory card in the Main control computer plugged in and electrically connected is.

As can be seen from the above, the rule data protected in the main control computer from being overwritten the by the control computer with the external memory is not electrically connected and can therefore change of data due to mistaken operation of data on delivery unit can be successfully prevented.
