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. Furthermore, when parts that have been arranged and piped are deleted, it is necessary to delete unnecessary parts and holes that are no longer needed.If the paper becomes dirty or damaged, it must be rewritten after all. There was

The present invention has been made in view of the above 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 in particular, piping It is an object of the present invention to provide a manifold block design support device that enables efficient and accurate design work by enabling the deletion of parts after completion.

[0007]

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.

In the present invention for such a manifold block design support device, the parts or holes designated by the operator are deleted after the piping connection by the automatic piping means 3 is completed, and at the same time, other parts which are no longer necessary due to the deletion are provided. It is characterized in that a deleting means 7 for deleting a hole is provided. Here, the deleting means 7 deletes a hole that has a connection with the part when the part is deleted, and that deletes the part and the number of connections with other parts and holes is 1 or less as an unnecessary hole.

[0009]

According to the manifold block design support apparatus of the present invention having such a configuration, the piping condition is examined after the piping connection by the automatic piping processing is performed between the plurality of parts arranged on the CRT screen. If there are unnecessary parts or holes, if you specify the unnecessary parts or holes and instruct them to be deleted, you can delete not only the specified parts or holes but also other holes that are no longer needed due to the deletion. ..

For this reason, when it is desired to change the parts arrangement after the pipe connection is completed, the deletion function is used to delete the plurality of parts to be replaced,
The parts that do not need to be deleted and their pipe connections can be effectively left, and it is easy to repeat the design work to place the parts again and perform automatic piping again.

4 and a mouse 26.

For the design support device 10, an appropriate external storage device such as a hard disk, a floppy disk, or a magnetic tape is used to input the input file 12 and the output file 1.
6, 18 are provided. The input file 12 stores a netlist file in which a portion formed by manifold blocks in the hydraulic circuit diagram is one unit, that is, each manifold block. The netlist file consists of a parts list and a netlist.The parts list identifies the parts name and number of hydraulic parts to be mounted on the manifold block, and the netlist identifies the nets of the hydraulic circuits that connect the hydraulic parts. To be done.

On the other hand, the library file 14 is used as a support library for the design work of the manifold block in the design support apparatus 10, and includes, for example, a parts database, a DRC (design rule check) table file, a plug table file, and a color table. It consists of files, nameplate list files, etc. Information on hydraulic components used in the design support device 10 is stored in the component database. The DRC table file stores check rules used for various inspections when the manifold block is designed. The plug table file stores information about plugs when holes are formed from the end faces of the manifold block.
The color table file stores color data for assigning specific colors according to the design work of hydraulic parts, piping, and plugs.

Further, as the output files 16 and 18, a design file and a processed data file are obtained.
The output file 18 as a processing data file is used for machining the manifold block. On the other hand, the output file 16 as a design file is used as an input file when a design change is made using a manifold block that has already been designed.

In the system configuration of the design support apparatus 10 of the present invention as described above, the design support apparatus 10 displays a five-view or three-view of the manifold block on the CRT screen 6 as shown in FIG. Means and input file 1
2 based on the operator's operation, the plurality of parts obtained from the parts list included in the netlist file
Between the plurality of hydraulic components by the shortest path search process when the connection point between the component arranging means 2 arranged on the plan or the three plan and the plurality of hydraulic components arranged on the five or the three plan is designated. As the deletion means 7 for deleting the parts or holes specified by the operator after the completion of the piping connection by the automatic piping means 3 and the automatic piping means 3 for simultaneously connecting other parts. Functions are provided.

Further, in this embodiment, further, a moving function for moving the parts for which the piping connection by the automatic piping means 3 is completed to a position designated by the operator while maintaining the connection relation of the piping, the automatic piping A completion inspection function of performing a completion inspection each time the process is completed, and a block reduction function of determining the suitability of the block size after completing all pipe connections and reducing the block size as necessary are provided.

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. Further, the dimensions of the manifold block on the initial screen can be set to a sufficient size with some allowance for the actual dimensions of the planned manifold block.

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. 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.

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 size will be changed when the piping of all nets is completed. It is larger.

Therefore, in step S10, block reduction processing is performed. The block reduction processing can be realized by designating the block size to be reduced in the horizontal and vertical directions on the screen. Further, instead of designating the block size in the horizontal and vertical directions, the block size can be reduced by pushing the block end face in the direction perpendicular to the surface. Furthermore, it goes without saying that changing the block size can not only reduce the size but also increase the block size. In such block size reduction (including expansion), the block size can be reduced while maintaining the connection relationship between the hydraulic components.

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, the deletion processing in the present invention will be described in detail. First, there are two deletion modes of the present invention: a part deletion mode and a hole deletion mode. In the case of the component deletion mode, by pointing the cursor to the target component and clicking it with the mouse, the target is designated as the target to be deleted, and then the delete command is executed.

As a result, the designated target component is deleted, and at the same time, the holes that are no longer needed due to the component deletion are also deleted. That is, a hole that is connected to the component when the component is deleted, and the component that has one or less connections with other components and holes due to the deletion of the component is deleted as an unnecessary hole.
On the other hand, in the hole deletion mode, the hole specified by the mouse click is deleted after the cursor is aligned, and in this case as well, the unnecessary holes due to the deletion of the hole are simultaneously deleted.

Next, an example of the deletion process of the present invention will be concretely described with reference to the screen explanatory views of FIGS. In the screen explanatory view of FIG. 7, the modular control valve 42 is arranged in the plan view 30 of the five views on the CRT screen 6, the screw type port 48 is arranged in the front view 32, and the right side view 34 is shown. Modular control valve 44 is arranged and left side view 36
It shows a state in which the pipe connection is performed by the automatic pipe processing after the screw type port 45 is arranged at the position.

With the pipes connected to each hydraulic component as described above,
Modular control valve 4 now placed in front view 30
2 shall be deleted. In this case, selecting the component deletion mode, aligning the cursor 46 with the modular control valve 42 to be deleted, and clicking the mouse,
The designated modular control valve 42 and the hole that becomes unnecessary when the modular control valve 42 is deleted are deleted.

FIG. 8 is an explanatory view of the screen after the modular control valve 42 is deleted. The modular control valve 42 is deleted by moving the cursor 46 and clicking the mouse, and at the same time, the modular control valve 42 is no longer necessary. The hole 50, that is, the hole 50 that connects the modular control valve 42 and the flange type port 45 on the left end surface of the block is deleted, and the hole 51 that is connected to the modular control valve 42 is also deleted.

Although FIGS. 7 and 8 show an example in which the hydraulic parts are designated and deleted, the holes connecting the hydraulic parts can be designated and deleted individually. 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 may be displayed. .. Since the display area per drawing can be increased in the case of the three-view drawing, it is suitable for complicated parts arrangement and piping design.

[0033]

As described above, according to the present invention, unnecessary parts and holes can be freely deleted according to the designer's judgment, for example, for rearrangement after the piping connection of hydraulic parts is completed. Since at the same time, other holes that have become unnecessary due to the deletion of parts and holes are also deleted, the deletion operation is easy and the efficient design work of the manifold block can be promoted.
