EP0511941A1 - Device for controlling of a spinning installation or of a spinning machine - Google Patents

Abstract

A spinning installation or spinning machine, which is designated diagrammatically by the field (7), is controlled by means of a computer program which is stored in a computer (1) and is displayed on a video screen (12) of a video-screen cabinet (2). The invention relates to the possibility of triggering the control commands directly by means of the video screen (12), or control fields 5 thereof, in a system according to display field (4). In this version, triggering takes place by touching the control fields (5.1. to 5.9) with the hand (14). To prevent a control field from being touched by mistake, an acknowledge key (15) can be provided so that a control command is executed only when a control command defined by a control field has been acknowledged by the acknowledge key (15). <IMAGE>

Description

The invention relates to a device for issuing control commands and for requesting, changing and displaying operating states relating to a spinning plant or spinning machine visualized on a computer screen with a plurality of interacting processing machines or processing units.

Such a system is known from the trade press (reprint from SIMATIC Report 4/87, S11-14) and includes a computer control with screen and keyboard and a computer-controlled control system for operating the spinning machines.

The system diagram for the processing process including certain display windows for further information can be shown on the screen.

The computer system contains various computer programs for correspondingly different processing processes.

The operator selects the desired program using the keyboard, and the corresponding system appears on the screen. Every detail of the system that has to be set separately for a certain process is visualized on the screen and can be assigned special values at the push of a button. These values appear next to the selected device symbol.

The operator is guided to the goal in the system with specific questions.

Changes in the system configuration correspond to the program changes to the corresponding computer program.

Such a control system has the essential advantage that changes and adjustments to the system configuration can be carried out by merely changing the program.

In terms of operation, from the point of view of the operating personnel, such a system requires knowledge and experience in dealing with a keyboard-controlled computer system.

This requires a certain routine in the operation of such a system in order to obtain at least not too frequent interruptions when operating such systems as a result of looking up the operating instructions.

Furthermore, the applicant showed a touchscreen system at the ITMA 1987 textile machine exhibition, by means of which certain states of selected functions of a doff system entitled "Interdoff" could be called up on a touchscreen. The touchscreen showed, for example, 10 touch fields, which were numbered 1 to 9 + 0, which were connected to various functions, for example the supply voltage for a servo motor could be called up. Certain monitoring functions of the machine movements could also be checked. There was a key switch to protect against unauthorized manipulation. The system was shown at the Rieter Scragg stand as part of the aforementioned textile machinery exhibition.

However, control operations such as those mentioned in connection with the aforementioned prior art could not be carried out with this control.

The object of the invention was therefore to simplify the operation of the computer system to the minimum requirement for the operating personnel.

According to the invention, the object according to the characterizing part of the first claim is achieved in that the device for issuing control commands and for requesting and displaying operating states is the screen itself.

Further advantageous embodiments are listed in the further dependent claims.

The advantage achieved by the invention lies essentially in the user-friendliness of the system.

The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment.

• Fig. 1 eine erfindungsgemässe Vorrichtung, steuerungsschematisch und mit einem erfindungsgemässen Computer-Bildschirm, schematisch dargestellt;
• Fig. 2 und 3 je eine Variante der Vorrichtung von Fig. 1;
• Fig. 4 bis 7 je eine weitere mögliche Bildschirmanzeige.

It shows:

• 1 shows a device according to the invention, shown schematically and schematically with a computer screen according to the invention;
• Figures 2 and 3 each a variant of the device of Fig. 1.
• 4 to 7 each another possible screen display.

1 shows a computer 1, a monitor box 2, a data memory 3 connected to the computer and a spinning plant or spinning machine 7, which is shown schematically as a rectangle.

Furthermore, an acknowledgment key 15 shown with dash-dotted lines is connected to the computer 1. The Computer 1 is further connected by means of a control line 9 for the transmission of control commands to the monitor box 2 and to a line 8 for the transmission of the computer program.

A visualized system diagram is shown on the screen 12 with the number 4, while 5 switch fields are delimited with the number.

These buttons 5 are again numbered individually, with a consecutive number after the number 5.

The function of these panels will be explained later.

A hand with an extended index finger is shown at 14, which symbolically touches one of the control fields, for example here control field 5.3, for the purpose of generating a corresponding control command.

FIG. 2 shows an alternative to the device of FIG. 1, in that instead of the hand 14 a mouse 6 directs a cursor 16 to the various switch fields of group 5.

The mouse 6 is connected to the computer 1 by means of a connecting line 17.

Analogously to FIG. 1, the acknowledgment key 15 is also connected to the computer 1 by means of a connecting line 15.1.

The remaining elements corresponding to FIG. 1 are provided with the same reference symbols.

FIG. 3 shows an alternative to the device of FIG. 2 in that the acknowledgment key 15 is omitted, in whose place the hand 14 receives an acknowledgment function.

FIG. 4 shows alternative figures on the screen 12, in that, on the one hand, the switch fields 5.4 to 5.9 are listed, but new visual fields 4.1 are shown instead of the system diagram 4.

In parallel to the visualized text fields 4.1, switching fields 5.10 are provided, the function of which will be explained later.

Also visualized on this screen are buttons 5.11, whose function will also be explained later.

5 likewise shows the control fields 5.4 to 5.9, but now has the display fields 4.2, which relate to processing lines 1 to 8 of the spinning plant. The processing lines are each provided with an L and a running number from 1 to 8.

The L-shaped bar 4.3 on the line field 6 is the characteristic of a fault here, for example in line 6.

6 shows the system diagram 4 corresponding to FIG. 1, the L-shaped bar 4.4 indicating a fault on the corresponding machine.

6 is a visualized text field 4.5.

The operation can be carried out as follows:

Example according to FIG. 1:
Initially, screen 12 is blank, or a general signet (not shown) may also be shown.

At the start, the control panel 5.6, which has the abbreviation Li, which means "line", is touched by hand 14, so that the line overview according to FIG. 5 appears, but without the fault display 4.3.

If line 5 is now to be put into operation, hand 14 touches control panel L5, so that, for example, system diagram 4 of FIG. 1 appears.

The system diagram 4 can only be an overview system diagram, which only represents the types of the various machines connected to one another, but not the exact number of each machine type.

The computer program can therefore be expanded further by visualizing a system scheme (not shown here) which shows all the machines in the line. In order to obtain such a representation, the hand 14 would touch the switch field 5.3 with the identifier P, which means "process sequence", so that the aforementioned detailed switch diagram would be visualized.

If line 5 could be put into operation with a pre-selected production output and pre-selected machine speeds, then only touching panel 5.1 with the "ON" indicator would have to be touched by hand 14 in order to put this line into operation. With the control panel 5.2 with the designation "OFF" it could also be switched off again.

However, if a new production output and new machine speeds are to be selected for this line 5, the hand 14 touches the control field 5.7 with the abbreviation “Da”, which means “data”, as a result of which the image shown in FIG. 4 appears on the screen 12.

Subsequently, the hand 14 touches the control panel 5.5 with the abbreviation "Se", which means "select", so that the production outputs and / or machine speeds listed in the display panels 4.1 are selected using the control panels 5.10. 4, the production output and the machine speed are listed in the upper field (the font required for this, however, is not shown).

Switching fields 5.10 can be used to switch from line to line in the upward or downward direction within the display field, the activated labeled line lighting up in each case.

If a power or a speed is to be changed, this can be adjusted with the buttons 5.11, the button with the letter X as the delete button and the button with the comma for decimal fractions.

Subsequently, the control panel 5.6 is touched again, so that the line overview according to FIG. 5 appears, whereupon the hand 14 touches the control panel L5, so that the system diagram 4 according to FIG. 1 appears again. The system can then be started by touching the 5.1 panel.

As an alternative resp. As a supplement to the switching commands by touching the switching fields, the acknowledgment key 15 can be actuated after each touching a switching field to confirm that a switching command is to be carried out, so that accidental touching of a switching field is excluded.

In the variant according to FIG. 2, the mouse 6 is used in combination with the cursor 16 instead of the hand 14 to move the to control the corresponding panels. The corresponding switching command is triggered by the switching button 6.1 of the mouse 6.

For safety reasons, the acknowledgment button 15 can be actuated, as in the device in FIG. 1, in order to prevent the switching function from being inadvertently triggered with the button 6.1.

In the variant according to FIG. 3, the mouse 6 and the cursor 16 are also present in order to control a corresponding switch field, and the switch function can also be triggered with the switch button 6.1.

To prevent accidental triggering of a switching function, the hand 14 can additionally touch the respectively selected switching field in order to enable a switching command only in combination with the pressure on the switching button 6.1 and touching with the hand 14.

Such safety precautions are not absolutely necessary when selecting fields 5.10 and 5.11 in order to change the production output or. the machine speeds according to FIG. 4, since this would rather unnecessarily complicate the corresponding selection; however, it is not excluded.

In FIG. 5, the display field 4.3 shows that a fault has occurred in line 6. The system diagram of this field can then be visualized as shown in FIG. 6 by actuating the field L6, the display field 4.4 (FIG. 6) showing on which machine the fault occurred.

In order to receive a written report on the fault, the control panel 5.4 can be activated so that the fault is listed in the display field 4.5.

The previous visualized image can be retrieved in each case with the button 5.8, identified by "Ba", which means "back".

With button 5.9, the whole visualization process can be brought to the initial stage. This field 5.9 has the designation "To Be", which means "to begin".

The European patent application with the publication number 0 452 676 A1 shows and describes a cleaning map for, for example, a fine cleaning machine, in which the intensity of the cleaning or the departure, i.e. the excretion of dirt and fibers can be adjusted in complementary variations.

In this application, we are only talking about a fine cleaning machine in which, for example, the stock between the clamping line on the feed trough and the take-over line of the clothing on the opening roller or the existence of a release agent (e.g. knife) can be adjusted to the impact circle of the clothing. One setting for changing the above-mentioned outlet consists, for example, in the displacement distance between a guide plate and a subsequent knife of the above-mentioned separation stage on the opening roller, with which the depth of the separation is set. The length of the separation gap between the knife and the guide plate of the separation stage on the opening roller can also be an adjustment influencing the outlet.

Fine cleaning machines, since they are provided in the cleaning process after the so-called coarse cleaning machines and receive pre-cleaned fibers for the further cleaning process, must be able to remove the fine dirt from the fiber template of the cleaning machine, this fiber template in a clamped form of a subsequent one The opening roller is fed in, so that the opening roller is able to enable fine resolution of the fiber template and thus fine cleaning.

In so-called coarse cleaning machines, which, as mentioned, are upstream in the cleaning process of the fine cleaning machine, coarse dirt is removed from the fiber flakes, which is usually done by means of pin rollers and grate bars arranged around them, by gripping the fiber flakes by the pins and pulling them over the grate bars, thereby the coarse impurities come out and reach a collection point between the grate bars.

However, it is also possible with such a machine to change the cleaning intensity, for example by changing the speed of the pin roller and changing the outlet in which the position of the grate bars can be changed. Such a machine is shown and described in the European patent application with the publication number 0 464 441 A1.

It is therefore possible with the help of the current application, as shown in FIG. 7, to use the cleaning map shown in EP 0 452 676 in FIG. 1 for any cleaning machine or opener machine on the screen 38 as a cleaning map 20 with the map boundaries 24 to use a cursor 16 or the finger of a hand 14 to define a working point 23 therein which defines the cleaning intensity on the ordinate 21 and the exit on the abscissa 22 and numerically displays them in the display boxes 27 and 28. The display box 27 shows the output in percent and the display box 28 shows the intensity with a relative number between 0 and 1.

The selected machine type is displayed with a display box 25 and with the display box 26 the range of fibers to be cleaned in the cleaning system.

The machine type and fiber range can either be connected to the computer by means of a keyboard 34, which is connected to a computer mentioned in EP 0 464 441 A1 by means of a connection 35, or by means of a connection 38 to the computer by means of a mouse 36, which is described as in the aforementioned application is. Furthermore, there is also the possibility of providing machine selection displays 29 to 33 on the screen, so that the machine type can be selected directly on the screen by hand (analogous to FIGS. 1 and 3) or by means of a cursor (analogous to FIG. 3, not shown in each case).

It is understood that the cleaning map does not have to be as shown in FIG. 7, the map can also have other configurations.

It is also possible to provide parameters other than the intensity and the departure, provided that there are two parameters that can be displayed in one area.

There is also the possibility of assigning the computer or the screen to a higher-level control in which the overall cleaning process is controlled, as was shown and described with the preceding figures, so that when the range is selected, this automatically appears on the screen shown in FIG. 7 is shown.

It is also possible to use the same screen for several machines that can work with a map, so that the individual machine types can be set one after the other.

To safeguard against unauthorized actuation of the touchscreen field, there is the possibility of providing operational security in connection with a control panel designated 5.4 and provided with a question mark by giving the authorized person a number code which, when operating the control panel 5.4, with one hand and entering the number code in the panels 5.11 of Fig. 4 allows actuation. In this way, there is also the possibility of providing different types of functionaries, for example an electrician, technologist or system administrator, with different code numbers if, for example, it is to be provided that the values, for example of technological importance, should only be changed by technologists.
