[0003]

When planning or studying the layout of a work space or parts during a design, each position subdivided by a vehicle division such as an engine room, a dash, a room, and a front door is determined. It is performed as a target. In this case, in a vehicle section where a large number of components are spatially arranged such as an engine room,
There are many places where designers must take charge of design studies. For this reason, although there is a design information database that stores the shape data of parts, etc., the designer must perform various examinations while identifying peripheral parts based on empirical knowledge, and overlook parts to be examined. There is a problem that there is a possibility that accurate examination cannot be performed.

[0004] Further, with the design information database alone, it is not possible to find out peripheral parts while taking into account a procedure which is an assembly order of parts arranged in one vehicle section.

Here, in order to conduct a design study in consideration of a part routing, it is necessary to search both a design information database and a production information database storing routing data and the like. As described above, since each piece of design and production information is individually owned and the design information and production information are not unified, the search efficiency is low. Therefore, in reality, it is not possible to accurately and efficiently examine the productivity and workability during the design while taking into account the procedure of the parts and accurately extracting the peripheral parts.

The present invention has been made in view of the above circumstances, and has as its object to provide a design support apparatus capable of accurately and efficiently examining productivity and workability during design.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing a design support apparatus according to an embodiment of the present invention, there have conventionally been the following problems.

Conventionally, in the design work, tool data is stored as CAD data, and a designer refers to the CAD data of the tool for design study.

However, when a designer intends to use the CAD data of a tool for design study, each part under design, or even the same part, must be mounted on each assembly line (in each factory or in a factory). However, since a tool to be used is different for each (line unit), an enormous amount of data must be referred to, and it takes a long time to check.

Further, if only the tool data is used, there is a problem that the working space of the hand to be secured for the work cannot be determined. Also, if the data of the tool is only the size, in the case of a tool used by moving like a torque wrench, there is a problem that the moving range (swing range) during use is not known.

Further, there is a problem that the operator does not know from which direction the tightening work is to be performed, and in which direction the angle of the worker's hand is established. Therefore, in reality, it is not possible to accurately and efficiently perform a design study on the assembling work.

Therefore, the design support apparatus is also required to be capable of easily conducting a design study on an assembling work, and the design support apparatus of the present embodiment is configured to satisfy this requirement.

Also, since the part name includes data on the vehicle section, even if only the part name is input, the design data of all the parts arranged in the vehicle section including the part is converted into the CAD data. Appears instantly on the screen. Therefore, there is no need to search for a vehicle section from the part name and input this vehicle section name, and it is not necessary to refer to design data.

Further, the retrieved design data of the parts is displayed according to the routing data. Therefore, when designing a part to be arranged in a certain vehicle section, it is possible to thoroughly identify parts arranged around the part to be designed while taking into account the order of assembling the parts. There is no more, and accurate examination can be performed efficiently. In addition, since the design data and the routing data, in other words, the design information and the production information are unified, the efficiency at the time of retrieval is high, and the part design in consideration of the production information can be performed easily and efficiently. it can.

Further, when the part name is input, the design data of the parts up to the input part, that is, the parts up to the previous step, out of all the parts arranged in the vehicle section including the part, The data is displayed on the CAD screen according to the data. When a part name is input in this way, only parts that are located in the vicinity of the design target among the parts arranged in the vicinity are displayed, so that it is easy to check the number of parts, etc. There is no more, and accurate examination can be performed more efficiently.

Further, since the design data includes the shape data of the component and the layout data of the component, sufficient information necessary for the examination can be obtained, and the component design can be optimally performed.

Further, by inputting the line name, C

As shown in FIG. 7A, the mounting position data table stores mounting positions for each part and for each assembly line.

As shown in FIG. 7B, the hand data table shows the hand shape (hand movement when swinging) for each tool model name and mounting direction. It is stored so that it can be displayed.

FIG. 8 shows the flow of decision making. Steps S21 to S28 are the same as steps S21 to S28 shown in FIG.
Since the same processing as in steps 1 to S8 is performed, the description thereof is omitted.

In S29, the input position is input by the input unit 2.

In S30, a tool model name and a size (including a moving range) are searched from the model data table and the bit box data table in accordance with the component name and the line name input in S21, S27 and S28.

In S31, first, S21, S27, S2
According to the component name and the line name input in step 8, a search is made from the mounting position data table to determine from which position the operator mounts the component. Then, it is determined from the position where the worker has already searched for the component to which position input in S29 is to be mounted (the mounting direction).

In S32, it is determined whether or not the work can be performed ergonomically. If the work cannot be performed, the process proceeds to S33 and "NG" is displayed.

If work is possible, the process proceeds to S34. In S34, an optimal hand shape is searched from the hand data table according to the tool model name searched in S30 and the mounting direction determined in S31.

In S35, the display position of the tool is corrected based on the mounting direction determined in S31, and the data is displayed on the screen together with the optimal hand shape obtained in S34.
