Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manifold block design support device for three-dimensionally designing a portion of a manifold block in a hydraulic circuit diagram.

[0002]

2. Description of the Related Art Conventionally, the design work of a manifold block used for hydraulic equipment is performed by drawing a six-sided drawing corresponding to the manifold block at a full scale or a half scale on graph paper.
In addition, all the parts to be placed are cut into paper and the designer
We will proceed with the piping work while arranging the pattern of the parts, assuming a pattern that will be arranged well on the floor plan.

Then, when the piping state for the manifold block can be roughly seen, a manufacturing drawing is drawn to check whether there is any interference between the actual piping and parts or whether the design rules are satisfied. If you find a problem, you'll either have to fix it, or in some cases, try again.

[0004]

However, in the design work of such a conventional manifold block, it is extremely difficult to change the arrangement of parts, piping, size of the block, etc. There is a problem that it takes a lot of effort. In other words, the designer keeps his concentration for a long time while gazing at the drawing and proceeding with the design in his mind. Therefore, when designing a block having a large number of parts and a high density of piping, it may take about one week.

Also, due to oversight, there are many cases in which there is interference in the layout and piping among those that have once been designed, and those that do not satisfy the design criteria. The present invention has been made in view of such conventional problems, and takes in design work into a computer to provide various functions in accordance with the flow of design work to support the same, and particularly after completion of piping. It is an object of the present invention to provide a manifold block design support device capable of performing an inspection automatically and efficiently and accurately performing a design work.

[0006]

FIG. 1 illustrates the principle of the present invention. First, the present invention is a display means 1 for displaying a five-view or three-view of a manifold block on a CRT screen 6.
And a component arranging means 2 for arranging a plurality of hydraulic components obtained from the hydraulic circuit diagram on a five-view or a three-view based on an operator's operation, and a connection point between the plurality of arranged hydraulic components. At this time, the object is a manifold block design support device provided with an automatic piping means 3 for connecting a plurality of hydraulic parts by piping by a shortest path search process.

According to the present invention for such a manifold block design support device, whether or not the piping design satisfying the design specifications initialized by receiving the instruction of the operator after the completion of the piping connection by the automatic piping means 3 has been performed. A feature is that a completion inspection means 7 for determining whether or not it is provided is provided. Here, the completion inspection means 7 determines whether all the ports specified for each net given in the design specifications are connected, whether all the holes of each net are connected, and whether unnecessary holes are formed. Please judge.

Further, when the completion inspecting means 7 determines a net in which piping is not completed, the target net on the CRT screen 6 is identified and displayed by hatching or the like.

[0009]

Further, the machining data output file 18 is used for machining the manifold block, while the design output file 16 is used as an input file when making a design change using the manifold block already designed.
In the system configuration of the design support device 10 of the present invention as described above, the design support device 10 displays a 5-sided view or a 3-sided view of the manifold block on the CRT screen 6 as shown in FIG.
Based on the display means displayed above and a plurality of parts obtained from the parts list included in the netlist file in the input file 12, five views or 3
When a connection point between the component placement means 2 to be placed on the floor plan and a plurality of hydraulic components placed on the five-view or the three-view is designated, a pipe connection is made between the plurality of hydraulic components by the shortest path search process. A function as the automatic piping means 3 and a function as a completion inspection means 7 for judging whether or not the piping design satisfying the initial design specifications upon receiving the instruction of the operator after the completion of the piping connection by the automatic piping means 3 is performed. It is provided.

Further, in this embodiment, further, a moving function for moving the parts for which the piping connection by the automatic piping means 3 has been completed to the position designated by the operator while maintaining the connection relation of the piping, the automatic piping Delete function that deletes parts or holes specified by the operator after the pipe connection by means 3 and at the same time deletes other holes that are no longer needed by the deletion, and determines whether the block size is appropriate after completing all pipe connections If necessary, a block reduction function for reducing the block size is provided.

FIG. 3 is a flowchart 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 35 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 view showing a state in which the component parts are arranged on the manifold block by designating the icon components A and B in the component display frame 35. Specifically, if the cursor is moved to the icon part A or B in the part display frame 35 and the mouse is clicked, then the position is moved to a 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 automatic piping is completed, and if there is a part or net to be moved, a movement process is performed in step S4. 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 component 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. Subsequently, 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. This 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. Details of this piping completion inspection processing will be made clear later.

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 drawing of the initial screen shown in FIG. 4, the block is completed at the stage when the 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. Furthermore, it goes without saying that changing the block size can not only reduce the size but also increase the block size.

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 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.

FIG. 7 is a flow chart showing the pipe completion processing performed by the manifold block design support device of the present invention. After the automatic piping process of the parts arranged as shown in the flow chart of FIG. 3 is completed, when the operator gives an instruction for the pipe completion inspection, the pipe completion process shown by the subroutine in FIG. 7 is executed.

In this piping completion processing, the contents of the netlist file provided in the input file 12 of FIG. 2 are used as design specifications, and it is determined whether a piping design satisfying these design specifications has been performed. First, in step S100, the net number is initialized to 0, and then in step S101, the connection is checked to see if all the designated ports designated by the net number = 0 are connected. At the same time, it is determined whether all the holes of the designated net are connected, that is, whether there are no isolated holes, and whether unnecessary holes are generated.

Subsequently, in step S102, if the check result satisfies the design specification, the process proceeds to step S104, it is determined whether or not the net is the final net, and the net number is incremented by 1 in step S105 until the final net is reached, and the net is again determined. The connection check with the designated port in step S101 is repeated. On the other hand, if all the ports specified by the net are not piped from the check result in step S102, there are isolated holes in the net, or if unnecessary holes are generated, the process proceeds to step S103. Go CR
Hatching is displayed for the incomplete nets displayed in each figure on the T screen to inform the operator that the nets are incomplete nets.

The above process is repeated until the final net, and the process returns to the main routine of FIG. Returning to the main routine of FIG. 3, if all net piping is completed in step S8, the process proceeds to step S9. However, if there is an uncompleted net, the process returns to the component placement in step S1 or the automatic piping process in step S2. Automatic piping is performed with new component placement that eliminates the completion net. Further, unnecessary holes are deleted in the deletion process of step S6.

FIG. 8 is an explanatory view of a screen when a net whose piping is not completed is found in the piping completion inspection shown in the flowchart of FIG. 8, a gasket valve 40 is arranged on the front view 30 on the CRT screen 6, a modular control valve 42 is arranged on the rear view 38, and a port 44 is arranged on the left side view 36. Further, a port 46 is arranged on the right side view 34. By performing automatic piping processing for such component placement,
Modular control valve 42 and port 4 as shown
4, a piping net that connects the port 48c of the gasket valve 40 is further formed, and a piping net 50 that connects the port 48d of the gasket valve 40 and the port 46 is further formed.

However, when the pipe completion inspection was conducted, the ports 48a, 48b, 48e of the gasket valve 40 were found.
Is not connected and there are unplaced parts for the piping net 50, and the ports 48a, 48b, 48d, 48e of the piping net 50 and the gasket valve 40 are found.
A hatching display indicating that the piping is not completed is displayed for each of the above.

For this reason, the operator knows the uncompleted piping portion from the hatched portion on the screen when the piping inspection is completed as shown in FIG. 8, and for example, the port 48a of the gasket valve 40,
Ports such as 48b and 48e and ports for the piping net 50 are newly arranged, automatic piping processing is performed again, and after completion of automatic piping, a piping completion inspection is performed again to confirm that a piping design satisfying the design specifications has been performed. ..

In the above embodiment, the design process in which the five views are displayed on the CRT screen 6 is taken as an example, but as another embodiment, the three views are displayed. May be. When a three-view drawing is displayed, the display area per drawing can be increased, which makes it easier to see the complicated piping design.

[0034]

As described above, according to the present invention, it is possible to automatically determine whether or not the current design state of the manifold block satisfies the initially set design specification, so that the piping by the designer can be determined. Can be prevented from being overlooked, and unnecessary processing can be avoided in the manufacturing process of the manifold block based on the design output data, and the design quality of the manifold block can be significantly improved.
