An assembly cell was retrofitted to measure and optimize cycle times. Customizable textile wristbands are produced in the assembly cell.
TODO: #66 Add integration for assembly analytics
factorycube sends the collected production data to the server. See also [factorycube].
Gateways connect the sensors to the factorycube.
Models:
Light barriers are installed on the removal bins and are activated when the employee removes material. Used to measure cycle time and material consumption.
Models:
Proximity sensors on the foot switches of sewing machines detect activity of the process. Used to measure cycle time.
Models:
The barcode scanner is used to scan the wristband at the beginning of the assembly process. Process start and product identification.
Model:
The customer opted for a combination of our SaaS offering with the building kit (and thus an on-premise option). The customer decided to go for PowerBI as a dashboard and connected it via the REST API with factoryinsight.
With the help of Assembly Analytics Nodes, it is possible to measure the cycle time of assembly cells in order to measure and continuously improve their efficiency in a similar way to machines.
Here is an exemplary implementation of those nodes:
There are 2 stations with a total of 4 cycles under consideration
Station 1 (AssemblyCell1):
1a: Starts with scanned barcode and ends when 1b starts
1b: Starts with a trigger at the pick to light station and ends when station 1a starts
Station 2 (AssemblyCell2):
2a: Starts when the foot switch at the 2nd station is pressed and ends when 2b starts
2b: Starts when the quality check button is pressed and ends when 2a starts.
Assumptions:
Nodes explained:
Assembly Analytics Trigger: Cycles can be started with the help of the “Assembly Analytics Trigger” software module.
Assembly Analytics Scrap: With the help of the software module “Assembly Analytics Scrap”, existing cycles can be aborted and that produced good can be marked as “scrap”.
With the help of the software module “Assembly Analytics Middleware”, the software modules described above are processed into “unique products”.
