Verifying the Assembly Instruction by Comparing with the Customer Order Sheet (Kanban)
In the process of assembling products such as automobile parts, by reading the barcodes on the
assembly instruction, product, and the customer order sheet (Kanban), the part to be assembled can
be specified and also you can check whether the assembly instruction and the customer order sheet
(Kanban) match.
Use the “Picking Verification” function.
Refer to 4-28
By bundling three barcode data as one set, up to 900 sets of master data can be registered (preset) in
the DV-90. Three barcodes are read in a row, and the output No. corresponding to the master data
that matches each of one of the barcodes is output in parallel transmission.
Eventually, when all the preset barcodes in a set match the master data, an OK output turns on. Oth-
erwise, an NG output turns on.
Let’s look at the example shown above.
First of all, preset all the combinations of the barcode data of the assembly instructions, products,
and the customer order sheet (Kanban) prepared for today’s production.
When the assembly operator reads the barcode on the assembly instruction, the lamp on the shelf
that contains the products to be manufactured illuminates. The operator places the indicated product
on the workbench. Then, when the operator reads the barcode on the product, the lamp on the shelf
that contains the part to be assembled on that product illuminates. The operator can then take the
indicated part and assemble it on the product.
Finally, the operator reads the barcode (Kanban) on the customer order sheet. If the assembly oper-
ation has been done properly, an OK output turns on. Otherwise, an NG output turns on.
