Gets or sets the grey zone.
Remarks
Remarks
This specifies the grey zone between 2 material packages. A grey zone is a zone
where the placement system can not determine where the switch between 2 material packages
has been taken place. Therefore the system tracks both material packages.
The quality of the GreyZone is driven by the process the customer is operating and if
the feeder are using optional splice sensor detectors or not.
Background is, that some sensors can detect the splice plate and the splice plate has a length
which covers a number of components which hide the real end of tape. Therefore the verifcation system
will report a greyzone between the "leading package" and the "trailing" in the chain.
The greyzone will be maintained typically by the machine, based on the feeder configuration. When the feeder has a sploice sensor the
grey zone will be calculated when the sensor detects the splice, and will be adjusted when components are consumed.
When the greyzone reached zero, the "leading" package will be consumed and the chain will be modified by removing the "leading" package
from the chain, resulting in the next package in the chain becoming the new "leading" package.
This sample scenarion explains the data change when consuming the material with a feeder with sensor:
| Action | Description | Resulting Chain | Greyzone |
|---|---|---|---|
| Inital | Material with a defined quantity is mounted. | A (100) | 0 |
| Production | Material will be consumed during production (20 components). | A (80) | 0 |
| Splicing | New Material will be spliced to the mounted material. | B(200) -> A (80) | 0 |
| Production | Material will be consumed during production (50 components). | B(200) -> A (30) | 0 |
| Splice detected | Feeder detects the splice and calculated the grey zone (here 10) and adjust the quantity because sensor overrules filling level information. Event will be triggered, that a quantity correction has been performed. | B(200) -> A (0) | 10 |
| Production | Material will be consumed during production (5 components). The material in the pickup location has a quantity of zero. The chain will be not be modified, because the greyzone is not zero. The material B will be consumed. | B(195) -> A(0) | 5 |
| Production | Material will be consumed during production ( components). The material in the pickup location has a quantity of zero. The chain will be modified, because the greyzone is zero. The material A will be consumed. An event will be send, that the mateiral A is been consumed. | B(190) | 0 |
| Production | Material will be consumed during production (50 components). | B(140) | 0 |
