What is a Billboard?

The billboard is a signal tool in the pulling system to start the next production process, or move the work in process to the downstream process. This term means "signal" or "signal board" in Japanese.

billboard

1. The downstream process orders products according to the exact quantity indicated on the billboard.

Approval

2 copies of the store's business license or business name approval number;

2 copies of the lease contract;

2 renderings of outdoor billboards (the renderings need to be in color, and you should shoot down about 80CM up and down the door)

Application report (including setting place, release time, content, form, specification, quantity; two copies);

2 copies of property right certificate;

1 store location map; (can be downloaded from Baidu or other websites, but the specific location of the store must be marked on the map);

The specifications of the advertisement are different for each district, and neither industrial and commercial nor urban management has made any regulations, depending on the external structure of the house.

Billboards have two functions in the production operation: instruct the production process to manufacture the product, and instruct the material operator to carry the product. The former is called production billboard (or manufacturing billboard), and the latter is called pickup billboard (or extraction billboard). The production billboard informs the upstream process of the type and quantity of products required for the downstream process. In the simplest case, for example, the upstream process prepares a production billboard corresponding to "a box of parts" in advance and puts it in a stock supermarket at the same time as a box of parts. When a box of parts is removed, a billboard is used to start production. Some signal billboards have a triangular shape, so they are also called triangle billboards.

Extraction of billboards indicates transport of parts to downstream processes. There are usually two forms: internal billboards and supplier billboards. In the beginning, cards were widely used in both forms in the urban area of Toyota. However, when lean production was widely used, suppliers farther away from factories switched to electronic billboards. To create a pulling system, production and extraction billboards must be used simultaneously: in the downstream process, when the operator takes the first product from the container, he takes an extraction billboard and places it on a nearby billboard In the box. When the hauler returns to the stock supermarket upstream of the value stream, he puts the extracted billboard into another billboard box, instructing the upstream process to produce a box of parts again. It is a real pulling system only when "you can't see the billboard, don't produce or move the product".
