Just in Sequence retrieval
At a predefined production step, just-in-sequence ( JIS ) call-offs provided by the OEM customer are retrieved from the ERP system and linked to the goods to be produced or picked. From this point on, each subsequent work step is checked and assured that the correct manufacturing or production sequence ( e.g. sequence, colour and equipment combinations, etc. ) is maintained and that processing is correct. Machine programs can be loaded automatically.
In the event of sequence breaks, operating errors or incorrect allocations, etc., immediate signalling takes place, for example on a terminal or via a signal light. If sequence breaks are caused intentionally ( e.g. when products that do not meet the quality requirements are rejected by the quality assurance department or when defects are detected ), this information is carried along in the subsequent production steps up to the goods-out stage and signalled to the operator. Thus the correct sequence is maintained.
At goods-out, the sequence is finally checked before it is delivered to the customer. Checking and ensuring that the correct production sequence is maintained can also be carried out across plant boundaries when production is carried out in several factories.
- In a JIS call-off, products are marked with an unique RFID tag that can be used to read and track subsequent sequencing.
- During all production steps, permanent monitoring is carried out using the AutoID / RFID middleware GRAIDWARE ®. Sequencing is carried along.
- Sequencing is recorded and taken into account when e.g. products are ejected for QA inspection or similar purposes.
- When products are put into JIS transport containers, the storage position is monitored using sequencing. This ensures that the storage is accurate to the sequence. If there is a risk of incorrect storage, this is signaled and prevented.
- At the shipping gate, the goods-out is posted and a shipping notification is created. Data can be continued across plants according to the supply chain.
