RPD Vaktari is a family of programs by RPD Engineering for knowing what is happening on the shop floor without having to go and look. Machines and vision systems already write files about what they do; Vaktari reads them and turns them into screens you look at with a browser, from any computer on the network.
Vaktari is Icelandic for watchman. In late 18th-century Reykjavík he was the man who walked the streets at night with a lantern and an hourglass, watching for fires and thieves, and who sang a verse every hour to let people know all was well.
The program does the same job in the factory: it keeps watch without stopping, and it warns.
Are the parts coming out right?
Reads the part-by-part measurements from the vision system and does the statistics: capability of each characteristic, alarms, control chart, Paretos and report.
Open the manual
Is the machine working?
Follows one machine from its SCADA: live state, availability, stops and their cause, most frequent errors and output.
Open the manual
How are all the machines doing now?
A single screen with every machine: lot counter, state by colour and an alert, with sound, when a lot reaches its target number of parts.
Open the manual
How did the lot go?
Puts in order the lot summaries saved by the vision system: counters, capability of each characteristic snapshot after snapshot, and the report of each lot.
Open the manual
How are several machines doing, in detail?
Shows the Vaktari Machine of several machines on a single page, each in its own tile. It needs Machine running on each machine.
Open the manual| I want to know… | Module | Where it gets the data |
|---|---|---|
| whether a characteristic is within tolerance and which one to correct | Measure | part-by-part measurements from the vision system |
| whether a correction has worked | Measure | part-by-part measurements from the vision system |
| how long a machine was stopped, and why | Machine | files from the machine's SCADA |
| which error costs the most time | Machine | files from the machine's SCADA |
| at a glance, which machines are running and which are not | Live Counters | counters of each machine |
| when a lot reaches the parts ordered | Live Counters | counters of each machine |
| how several machines are doing at once, in full detail | Hub | the Vaktari Machine of each machine |
| how a lot from a week ago ended | Statistic | lot summaries from the vision system |
| the report of a lot, to file or to send | Statistic | lot summaries from the vision system |
