  The selection unit 6 is for selecting one of a rolling stand and a rolling material manufactured by the rolling stand. The selection unit 6 is, for example, a device for manually performing the above selection such as a push button or a changeover switch. In such a case, the selection by the selection unit 6 is manually performed by the user of the display system. The selection by the selection unit 6 may be performed automatically. In such a case, the selecting unit 6 selects a rolling material while the rolling material is manufactured by, for example, a rolling stand. The selection unit 6 selects the rolling stand while the rolling material is not manufactured by the rolling stand.

The selection by the selection unit 6 may be performed both automatically and manually. In such a case, if the manual selection is not performed, the selection unit 6 performs automatic selection according to the conditions. The selection unit 6 gives priority to the manually selected result to the automatically selected result when the manual selection is performed.
The selection by the selection unit 6 is not limited to these methods.

  The selection by the selection unit 6 is performed to select one to be displayed in an emphasized manner on the display 7. When the rolling stand is selected by the selection unit 6, the display control unit 5 controls the display of the display 7 so that the visibility of the rolling stand is higher than that of the rolled material. Thereby, the state of the rolling stand is displayed in detail on the display 7, and the display related to the rolled material is simplified. When a rolling material is selected by the selection unit 6, the display control unit 5 controls the display of the display 7 so that the visibility of the rolling material is higher than that of the rolling stand. Thereby, the state of the rolled material is displayed in detail on the display 7, and the display regarding the rolling stand is simplified.

  Next, an example in which the present display system is applied to a rolling line will be described. FIG. 2 shows a display example of the display 7 when the display system shown in FIG. 1 is applied to a rolling line. The rolling line includes a plurality of manufacturing devices, such as a shear 10, an FSB 11, an edger 21, a rolling stand 12, a runout table 13 and a down coiler 14. FIG. 2 shows a display example when the present display system is applied to a rolling line provided with seven rolling stands 12. The to-be-produced product manufactured by the manufacturing apparatus of a rolling line is a metal plate (rolling material 15).

  The user of the display system sees the display on the display 7 shown in FIG. 2 and inputs the manufacturing apparatus to be enlarged and displayed using the input unit 16. The function of the input unit 16 is a function provided to the display device 1 as necessary. For example, a keyboard or a mouse may be provided as the input unit 16. Hereinafter, the operation of the display system when one rolling stand 12 is selected as a manufacturing apparatus to be enlarged and displayed will be described as an example with reference to FIG. FIG. 3 is a flow chart showing an operation example of the display system shown in FIG.

When one rolling stand 12 is selected as a manufacturing apparatus to be enlarged, the calculation units 2 and 3 acquire information necessary for calculation from the storage unit 4 and the detection devices 8 and 9 (S101). The information acquired by the calculation units 2 and 3 in S101 includes, for example, the following information.
I) Information which rolling material 15 originally has: 2nd information Chemical composition of rolling material 15, thickness, width, length of raw material (slab), thickness, width as product target value, etc. II) From rolling stand 12 upstream Information taken over: second information Thickness profile, thickness, temperature, width direction thickness profile (plate thickness distribution), flatness etc. of rolling material 15 on the entry side of rolling roll III) Information of rolling mill: First information of rolling roll Actual values of rotational speed, actual values of roll gap, profile of roll width direction (distribution of roll diameter considering thermal expansion amount and wear amount), dimensions of each component (detailing display and skeleton display of rolling mill) Information necessary for), etc. Note that the profile in the width direction of the roll can be calculated using a model.

The calculation unit 2 performs a calculation necessary to display the state of the rolling stand on the display 7 based on the acquired various information (S102). The calculating part 3 performs calculation required to display the state of the rolled material 15 which passes the said rolling stand on the indicator 7 based on the acquired various information (S102).

IV) Various information in the rolling roll bit Deformation resistance, rolling load, advance rate and reverse rate, neutral angle, biting angle etc. V) Various information on the rolling roll exit side Thickness, width, temperature, width direction Thickness profile (plate thickness distribution), flatness, position etc.

  The display control unit 5 causes the display 7 to simultaneously display the state of the rolling stand 12 and the state of the rolling material 15 based on the information acquired in S101 and the information calculated in S102 (S103). At this time, the display control unit 5 displays in detail the state of one of the rolling stand 12 or the rolling material 15 according to the selection result by the selection unit 6 and displays the other state in a simplified manner. The functions of the display control unit 5 will be specifically described below with reference to FIGS. 4 to 8 as well.

  FIG. 4 is a general view showing the appearance of a manufacturing apparatus and a product manufactured by the manufacturing apparatus. The manufacturing apparatus performs processing such as processing or painting on an object to be manufactured. When the product before processing enters the manufacturing apparatus, the processing apparatus applies a process to the product. The processed product is unloaded from the manufacturing apparatus. Generally, the manufacturing apparatus is covered by the case on the outside. For this reason, it is not possible to view the equipment and the product present inside the case from the outside. Also, even if the manufacturing device is not covered by the case, the part where the equipment interferes can not be seen from the outside.

  Therefore, when the rolling material 15 is selected by the selection unit 6, the display control unit 5 gives priority to the display of the rolling material 15 over the display of the rolling stand 12, and the rolling which passes through the rolling stand 12 from the state of the rolling stand 12 The state of the material 15 is displayed on the display 7 in more detail.

  FIG. 5 is a view showing a display example of the display 7 when priority is given to the display of the rolled material 15. For example, the display control unit 5 three-dimensionally displays the state of the rolling stand 12 and the state of the rolling material 15 on the display 7. At this time, as shown in FIG. 5, the display control unit 5 three-dimensionally displays the state of the rolling material 15 on the display 7 so that the portion behind the rolling stand 12 in the rolling material 15 can be visually recognized. Display. With regard to the display of the rolling stand 12, the display control unit 5 sets the state of the rolling stand 12 so that the external appearance of a part or all of the machines in contact with the rolling material 15 among the machines constituting the rolling stand 12 can be viewed. Display on the display 7. FIG. 5 shows an example in which the display unit 7 displays a skeleton of the rolling rolls 17 for extending the rolling material 15 thinly. In addition, the display method which gives priority to the display of the rolling material 15 is not limited to this.

  When the rolling stand 12 is selected by the selection unit 6, the display control unit 5 gives priority to the display of the rolling stand 12 over the display of the rolled material 15, and the rolling stand 12 according to the state of the rolled material 15 passing through the rolling stand 12. Is displayed on the display 7 in more detail.

  FIG. 6 is a view showing a display example of the display 7 when priority is given to the display of the rolling stand 12. For example, as shown in FIG. 6, the display control unit 5 three-dimensionally displays the state of the rolling stand 12 on the display 7 so that a portion behind the rolling material 15 in the rolling stand 12 can be visually recognized. Let Regarding the display of the rolled material 15, the display control unit 5 causes the display 7 to display the state of the rolled material 15 so that the outer shape of a part or all of the rolled material 15 can be viewed. FIG. 6 shows an example in which the thickness of the rolled material 15 is ignored, and the rolled material 15 is two-dimensionally displayed on the display 7 as a skeleton. In addition, the display method which gives priority to the display of the rolling stand 12 is not limited to this.

  As described above, by displaying more information of one of the rolling stand 12 and the rolling material 15 than the other, it is possible to appropriately display according to the user's request or the situation at that time. In addition, by displaying one of the portions in a shadowed manner in detail and simplifying the other display, sharpened display can be performed, and visibility can be improved. In order to further enhance the visibility of one, it is preferable to make the other a transparent display as in the above example. If it is the above-mentioned example, the state where rolling material 15 is rolled by rolling roll 17 can be displayed on indicator 7 in detail. In addition, when one of the displays is a transparent display, the display unit 7 may display in detail how the motor 18 of the rolling stand 12 is rotating.

  Further, when an output item is designated (S104), the display control unit 5 may display information on the designated item on the display 7 (S105). The specification of the output item is performed using, for example, the input unit 16. Also, the items that can be specified are set in advance.

  When the rolling material 15 is selected by the selection unit 6, only the item related to the rolling material 15 may be specified. FIG. 5 shows an example in which the thickness and the width of the rolling material 15 on the entry side of the rolling roll 17 are designated as output items. The display control unit 5 causes the numerical data of the designated item to be additionally displayed in the vicinity of the portion on the entering side of the rolled material 15 simulated and displayed using a rolling model or the like.

  The display control unit 5 may highlight a part or all of the rolling material 15 when displaying information on the designated item on the display 7. FIG. 7 is a diagram showing an example in which the rolling material 15 on the outlet side of the rolling roll 17 is highlighted. For example, when the rolling material 15 on the exit side of the rolling roll 17 is clicked with a pointer while the content shown in FIG. 5 is displayed on the display 7, the thickness of the central portion of the rolling material 15 is greater than the thickness of the end It changes to the highlighted display.

  The rolled material 15 has a quality index called a plate crown. It is difficult to form the rolled material 15 completely flat across the width direction. The rolled material 15 generally has a thick central portion in the width direction and a thin end. The difference between the thickness of the central portion in the width direction of the rolled material 15 and the thickness of a portion several tens of mm inward from the end portion is called a plate crown. The plate crown is often on the order of 0.1 mm. Therefore, when the rolled material 15 is displayed on the display 7 on an actual scale when the plate crown is designated as an output item, it is difficult to distinguish the difference in thickness of the rolled material 15 from the display of the display 7.

  Therefore, as shown in FIG. 7, the difference in thickness of the rolled material 15 is emphasized and displayed on the display 7. Thereby, the difference in the thickness of the rolling material 15 can be easily grasped | ascertained from the display of the indicator 7. FIG. In addition, when the rolling material 15 is selected by the selection part 6, the display of the rolling stand 12 is simplified. For this reason, even if the rolling material 15 is highlighted, the boundary between the rolling material 15 and the rolling stand 12 does not become difficult to see. In addition to the plate crown, when data such as the plate width, thickness and flatness of the rolled material 15 are additionally displayed, the target portion may be highlighted.

  The display method of the information regarding the designated item is not limited to the above. For example, the information related to the designated item may be additionally displayed on the display 7 using a diagram, a graph, a video, etc. in multi-dimensional display.

  On the other hand, when the rolling stand 12 is selected by the selection unit 6, only the item related to the rolling stand 12 may be specified. FIG. 6 shows an example in which the number of revolutions / torque / current of the motor 18, the load of the draft device 19 and the speed of the rolling roll 17 are designated as output items. The display control unit 5 causes the numerical data of the designated item to be additionally displayed in the vicinity of each of the motor 18, the pressure reduction device 19, and the rolling roll 17.

  The display control unit 5 may highlight a part or all of the rolling stand 12 when displaying information on the designated item on the display 7. FIG. 8 is a view showing an example in which the cross section of the rolling roll 17 is highlighted. For example, when the rolling roll 17 is clicked with a pointer so as to designate the cross section of the rolling roll 17 when the content shown in FIG. 6 is displayed on the display 7, the display changes to the cross section display highlighting the difference in diameter of the rolling roll 17. .

  When the rolling material 15 has a high temperature, the rolling rolls 17 thermally expand due to the heat received from the rolling material 15 and the heat due to the friction with the rolling material 15 or the like. In addition, the rolling rolls 17 wear due to contact and friction with the rolling material 15. The cross section when the rolling roll 17 is cut in the width direction has a complicated shape due to thermal expansion and wear. However, the amount of change in the diameter of the rolling roll 17 is small compared to the diameter. Therefore, when the cross section of the rolling roll 17 is displayed on the display 7 on an actual scale, it is difficult to distinguish the difference in diameter of the rolling roll 17 from the display of the display 7.

  Therefore, as shown in FIG. 8, the difference in diameter of the rolling roll 17 is emphasized and displayed on the display 7. Thereby, the difference in the diameter of the rolling roll 17 can be easily grasped | ascertained from the display of the indicator 7. FIG. If the detection device 8 for detecting the cross-sectional shape of the rolling roll 17 is provided inside the rolling stand 12, the detection result by the detection device 8 may be used for display. When such a detection device 8 is not provided, for example, the cross-sectional shape of the rolling roll 17 can be obtained from the calculation result by simulation using the shape model of the rolling roll 17. In addition to the cross-sectional shape of the rolling roll 17, when displaying various information, highlighting of the symmetrical part may be performed.

  The display method of the information regarding the designated item is not limited to the above. For example, the information related to the designated item may be additionally displayed on the display 7 using a diagram, a graph, a video, etc. in multi-dimensional display.

  In the above description, after the calculation units 2 and 3 have performed all calculations necessary for various displays, the display control unit 5 selects necessary information according to the selection result by the selection unit 6 and displays it on the display 7 I did. This is an example. The operation units 2 and 3 may perform only the operation necessary for display at that time according to the selection result by the selection unit 6.

  When the display system includes the camera 20 as shown in FIG. 1, the display control unit 5 may cause the display 7 to display an image captured by the camera 20. For example, when the camera 20 (first camera) captures a rolled material 15 manufactured by the rolling stand 12, the display control unit 5 captures an image by the camera 20 if the rolling material 15 is selected by the selection unit 6. The state of the rolled material 15 is displayed on the display 7 using a part of the image.

  FIG. 9 is a view showing a display example of the display 7 in the case of using an image taken by the camera 20. As shown in FIG. The part of the rolling material 15 disposed inside the rolling stand 12 can not be photographed by the camera 20. However, the portion of the rolled material 15 that has come out of the rolling stand 12 can be photographed by the camera 20. FIG. 9 shows an example in which the portion of the rolled material 15 that has come out of the case is replaced with a real image by the camera 20 from the display by simulation.

  On the other hand, when the camera 20 (second camera) captures an image of the rolling stand 12, the display control unit 5 partially uses the image captured by the camera 20 if the rolling stand 12 is selected by the selection unit 6. The state of the rolling stand 12 is displayed on the display 7. This is a particularly effective means when the camera 20 shoots an apparatus present inside the case.

  FIG. 10 is a diagram showing another configuration of the display system in the embodiment 1 of the present invention. The display system shown in FIG. 10 includes displays 7a and 7b. The display control unit 5a controls the display of the display 7a. Selection by the selection unit 6a is performed to select an object to be displayed in an emphasized manner on the display 7a.
