Description

[Detailed description of the invention] (Industrial application field) This invention relates to a device that selects and instructs necessary parts for each vehicle from a plurality of parts on a parts shelf placed at each assembly position on an automobile assembly line. It is.

(Prior art) In general, each assembly position on an automobile assembly line is equipped with a parts shelf containing various parts according to the car model and type, and for each car, the parts shelf corresponding to the car is selected. The necessary parts must be selected and installed.

Conventionally, as an information means for selecting the necessary parts, a sticker indicating the specifications of the vehicle or parts is pasted on the vehicle, and this sticker is visually read by the worker at each assembly position on the assembly line and the necessary parts are picked up from the parts shelf. The parts were removed and installed on the vehicle. As a result, incorrect selection of necessary parts or missing parts may occur due to reading errors by the operator, and when there are many types of required parts, the operator may have to check the location of the required parts on the parts shelf, the contents of the instructions, etc.
It is necessary to memorize part symbols, which places a heavy burden on the operator.

As a countermeasure to these problems, there are examples of installing lamps, etc. at each parts location on the parts shelf, and displaying the corresponding parts for each car by lighting, but this requires wiring work, and this is not possible due to cost, versatility, process improvement, etc. There was a problem with relocation, etc.

(Purpose of the invention) This invention can accurately and quickly indicate the necessary parts for each vehicle on the parts shelf at each assembly position on the automobile assembly line without visual inspection or judgment by workers. The purpose of the present invention is to provide a device that can easily deal with changes in instructions and contents of instructions.

(Structure of the invention) In order to achieve the above purpose, this invention includes a host computer that stores the specifications of necessary parts for each vehicle, and transmits information about each vehicle that enters the vehicle assembly line to the host computer. A control device that checks the specifications of the necessary parts for each vehicle output from the host computer based on this transmission information and sequentially transmits it to each assembly position on the vehicle assembly line; a parts shelf placed at each assembly position; It consists of a floodlight that illuminates the position of the necessary parts for each vehicle on the parts shelf using signals from the control device. It consists of a symbol display device, a symbol display device for the necessary parts, and a light pen that indicates the location of the necessary parts on the monitor television.

(Explanation based on Examples) This invention will be described below based on drawings showing Examples. At the entrance 1a of the vehicle assembly line 1, a control device 2 is connected to a multiplex transmission cable 4, which inputs information (vehicle number, etc.) on the vehicles 13 entering the line 1 and outputs it to the host computer 3. The host computer 3 stores the specifications of necessary parts for each vehicle, and outputs this to the control device 2.
The control device 2 checks the specifications of the necessary parts, memorizes the order in which the vehicles flow, and sends information on the necessary parts to each assembly position on the assembly line via the multiplex transmission cable 4, one vehicle at a time according to the flow of vehicles. introduce. A component shelf 7 is arranged at each assembly position, and a connector 5 is attached to the multiplex transmission cable 4. A projector 6 can be connected to the connector 5 if necessary. The light projector 6 has a monitor television camera 8, a monitor television 9, a symbol display device 10 as necessary parts, a light pen 11, and a light projecting lens 12. When information on the necessary parts for each vehicle is transmitted from the host computer 3 to the control device 2 to the floodlight 6, it is displayed on the symbol display device 10 for the necessary parts, and the light emitting lens 12 displays a section of the parts shelf 7 (the part concerned). (accommodation compartment) is irradiated with a laser beam in spots. The light pen 11 is used to indicate the changed position on the monitor television 9 when the storage position of the necessary part on the parts shelf 7 is changed, and to illuminate the changed position on the parts shelf 7 with the projector 6. Ru. The light projector 6 can be moved to each assembly position on the assembly line as needed, and even if it is moved, it can illuminate the position on the parts shelf corresponding to the required part at the moved assembly position.

(Effects of the invention) Since this invention has the above-described configuration, the necessary parts for each vehicle can be accurately and quickly selected on the parts shelf at each assembly position on the automobile assembly line. Therefore, there is no fear of installing incorrect parts at each assembly position, and work efficiency is improved. Furthermore, compared to the conventional method of arranging lamps and the like on a parts shelf, wiring work for the lamps is not required, resulting in cost reduction, and it is possible to easily deal with the relocation of equipment, changes in instructions, etc.
