Regarding a management device.

[Prior Art] In the vehicle production process in a factory, multiple types of vehicles are often manufactured on the same line in each process, and in particular, as consumer tastes have diversified in recent years. The variety of vehicles has also increased significantly.

By the way, vehicle manufacturing in a factory is divided into various processes such as intermediate coating, top coating, inspection, etc., taking the production line of a paint factory as an example. In order to improve this, it is necessary to efficiently manage vehicles by accurately grasping the current number of vehicles in stock and specification information for each vehicle in each process where vehicles are continuously transported and unloaded.

For this purpose, in the past, a limit switch was provided at the loading and unloading section of vehicles in each process, and a worker operated the limit switch to supply a counting signal to a counter each time a vehicle was loaded or unloaded. I was managing the number of machines. In addition, a correction increase/decrease switch was used to cope with errors in the number of vehicles entered when initially setting the number of vehicles or errors in inputting the limit switch.

FIG. 4 shows an example of such a conventional device.

In the figure, along production line 1, vehicles 2a~
2k are streamed sequentially. A drying oven 4 is installed within the coating process 3. A limit switch 5a is installed at the vehicle entrance to process 3, and a limit switch 5b is installed at the exit.Each time a vehicle is loaded or unloaded, a worker operates the limit switches 5a and 5b to display the count display panel. By inputting a signal to 6, the current number of vehicles in stock is displayed. If the number of vehicles displayed is incorrect when setting the initial number of vehicles, or if there is a discrepancy in the number of vehicles displayed due to a limit switch input error, etc., this can be corrected by operating the correction switch 7 to increase or decrease the number of vehicles displayed. .

[Problems to be Solved by the Invention] Conventional equipment with such a configuration can only manage the number of vehicles in a process, and cannot grasp the location and specification information of each vehicle, making it difficult to manage detailed information. The drawback was that inventory management was not possible. Also,
Since the counting signal was sent not only to the vehicle itself but also when the trolley on which the vehicle was placed was brought in and out of the process, a problem occurred in that empty trolleys were also input.

[Object of the Invention] The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide an in-process vehicle that can grasp detailed and accurate information on in-process vehicles and efficiently manage production. The objective is to provide a management device.
