FIG. 3 is a flow chart showing a manifold block design process by the design support device 10 of FIG. First, when the code number of the manifold block to be designed is designated by activating the design support device 10 of the present invention, the process proceeds to step S1 and the hydraulic component placement process is performed.

FIG. 4 shows an example of an initial screen in the component arrangement in step S1. In FIG. 4, in the center of the CRT screen 6, a five-view drawing of the manifold block is displayed in this embodiment. That is, the plan view 30, front view 32, right side view 34, left side view 36 and rear view 38 of the manifold block are displayed. Also, the dimensions of the manifold block in the initial screen are planned to be reduced to the limit after the completion of all design work. It can be set as a large enough size.

In the parts display frame 40 of the CRT screen 6, hydraulic parts used for designing the manifold block are used as icons. In this embodiment, the case where two parts A and B are used is taken as an example, and will be referred to as icon parts A and B in the following description. This icon part A,
B shows a modular control valve, a cartridge valve, a gasket valve, and various ports used in the actual design of the manifold block as a figure without omitting the image, and the part numbers are also shown. Therefore, without looking at the contents of the list of the part numbers, the designer can immediately know what kind of hydraulic part it is by looking at the icon parts A and B.

FIG. 5 is an explanatory diagram showing a state in which icon parts A and B in the part display frame 40 are designated and parts are arranged on the manifold block. Specifically, if the cursor is moved to the icon component A or B in the component display frame 40 and the mouse is clicked, then the cursor block is moved to the position on the front view 30 of the destination manifold block and the click operation is performed. The layout display of the parts is performed with the outer shape of the actual hydraulic part A corresponding to the icon part A at the specified position on the front view 30. The same applies to the movement of the icon component B.

Referring again to FIG. 3, if the component placement is completed in step S1, the process proceeds to the next step S2, and the automatic piping process for each net is executed. For example, as shown in FIG. 5, the automatic piping of each net has a port of the hydraulic component A and a hydraulic component B in a state where the hydraulic component A and the hydraulic component B are arranged.
When an operator issues an instruction for automatic piping by designating between two points of the port, the shortest path search processing is three-dimensionally executed to generate the automatic piping result shown in FIG. 6, for example.

Next, in step S3, the operator determines whether or not there is a part or net to be moved in a state where the automatic piping is completed, and if there is a part or net to be moved, the subject of the present invention is step S4. Move processing is performed. In this movement process, move the cursor to the net or part that is the target of movement and specify it as the movement target, and then move the cursor to the position you want to move and click to move the part or net while maintaining the overall piping connection relationship. Can be moved.

Subsequently, in step S5, it is checked whether or not there is a part or net (hole) to be deleted, and if there is, the deletion is performed in step S6. This deletion process may be performed by pointing the cursor to the component or net to be deleted and executing the deletion command. The details of this deletion processing will be clarified later. Then, at the stage where the design process for the specific net is completed, the process proceeds to step S7, and a pipe completion inspection is performed. The piping completion inspection automatically determines whether or not the current design state satisfies the design specifications of the manifold block given as the input file.

Then, in step S8, it is checked whether or not the piping of all the nets is completed. If the piping is not completed, the process returns to step S1 and the same operation is repeated from the next component arrangement, or the process returns to step S2. Repeat the process from the automatic piping of the next net. When the completion of piping of all nets is determined in step S8, the process proceeds to step S9, and it is determined whether the block size in the current design state is appropriate.

In the design support apparatus of the present invention, if the manifold block is set with a dimensional allowance in the five-view diagram of the initial screen shown in FIG. 4, the block is completed at the stage when piping of all nets is completed. The size is larger.
Therefore, the process proceeds to step S10 and block reduction processing is performed. In the block reduction processing, the block size can be reduced by designating the block range to be reduced in the horizontal and vertical directions on the screen. The block size can be changed not only by reducing but also by increasing.

When the block reduction processing is completed in step S10, it is checked in step S11 whether or not it is necessary to move or delete the part or net, and if it is necessary, the process returns to step S3 to move and / or delete. Process.
If it is not necessary to move or delete the part or net, the process returns to step S9 again to judge whether the block size obtained by the block reduction is appropriate or not, and if it is the optimum size, the series of design processes is ended.

Next, C according to the display mode designation processing of the present invention.
The display operation of the RT screen will be described in detail. FIG. 8 is a flow chart showing the display process of the manifold block of the present invention. In step S1, it is determined whether the operator selects the mode 1, the mode 2 or the mode 3.

When the designation of mode 1 (first mode) is determined, the process proceeds to step S2, and only the parts arranged on the front surface are displayed. When it is determined that the mode 2 (second mode) is designated, the process proceeds to step S3, and only the front and rear layout components are displayed. Further, when the mode 3 (third mode) is designated, the process proceeds to step S4, the block is made transparent, and a pipe perspective view showing the internal pipe state is displayed.

FIG. 9 shows step S in the designation of mode 3 in FIG.
4 is a flowchart showing a mode designation process for net display performed in the state of displaying a perspective view of piping in FIG. In the net display of FIG. 9, the designation of mode 1, mode 2 or mode 3 is determined in step S1. When the mode 1 is determined, the process proceeds to step S2, and the pipe is displayed in solid color with the designated color. When mode 2 is designated, the pipe portion is hatched in step S3.
Further, when mode 3 is designated, the pipe is displayed by the thinned center line in step S4.

FIG. 10 is a screen explanatory view of the CRT screen 6 displaying only the surface arrangement parts in the mode 1 designation of FIG.
Only the hydraulic parts arranged on the respective surfaces of the five views are displayed. FIG. 11 is an explanatory view of the screen in which only the front and rear arrangement parts are displayed by designating the mode 2 in FIG. 8, and in addition to the front surface only parts of FIG. The parts located at are also displayed together with the parts on the opposite surface.

FIG. 12 is a screen explanatory view showing a perspective view of piping by selecting mode 3 in FIG. 8 to make the block transparent. In addition to the display of the component arrangement on the front and back sides of FIG. The piping connections of the net formed by the design process are displayed in a transparent state. In this case, the color of the pipe connection is displayed differently for each net. Further, in the screen explanatory view of FIG. 12, the pipe is displayed in solid by the mode 1 designation in FIG. 9, and the net is displayed by solidly painting the specified color in the portion showing the thickness of the pipe. is doing.

FIG. 13 is an explanatory view of the screen when the piping is hatched by selecting the mode 2 in FIG.

FIG. 10 is an explanatory view of a screen in which piping is displayed on a center line by designating mode 3 in FIG. 9. That is, as shown in FIG. 12 and FIG. 13, when the pipe is displayed with the designed thickness, the internal structure close to the actual processing state can be known, but it is difficult to determine the pipe connection state. .. Therefore, by displaying the pipes as the center lines as shown in FIG. 14, the internal pipe connection state can be simply displayed, and the pipe connection state between the ports of the hydraulic components can be easily visually judged.

FIG. 15 is an explanatory view of the screen in the hatching display of the piping shown in FIG. 13 when only the net of interest is designated and highlighted by solid painting. That is, according to the present invention, all nets are basically designated to specify solid painting, hatching, and center line in the modes 1 to 3 of FIG. 9, but each net is designated individually. You can decide the net display mode.

FIG. 16 shows a special display mode in the perspective view display of the piping state according to the present invention. In this embodiment, the manifold block is cut along a virtual plane, and a five-sided view is shown. Applied to the display of. The cutting virtual plane is a plane perpendicular to each of the horizontal axis X, the vertical axis Y, and the depth axis Z. FIG. 16 shows a case where a virtual cutting plane 42 perpendicular to the horizontal axis X is set, and in the right side view 34, parts and piped holes that are present on the right side of the virtual cutting plane 42 are displayed in a transparent state. Further, in the left side view 36, a perspective state of parts and piped holes existing on the left side of the virtual cutting plane 42 is displayed. In this embodiment, the cut virtual plane can be set to a maximum of three planes.

In the above embodiment, the case where the five views are displayed on the CRT screen 6 to proceed with the design process is taken as an example, but as another embodiment, the three views are displayed. Good. In the case of the three-view drawing, the display area per drawing becomes large, which is advantageous for complicated piping design.
