Description of automation problem
Color inspection for a new order which the client give to the factory as a part of component have that color and the client want the same color with the same degree.
This is... a big problem to the factory according to many times of try and error to make the color like it and with the same degree.
Control requirements
The automation solution is to design an automation system which can analyze any given color and make it from the basic colors.
The individual color compositions are selected via a recipe display which includes all parameters.
If a recipe or parameter is changed, this change will be documented in a modification logbook (audit trail file). This enables to subsequently determine which person processing made this change and possible wrong fillings can be verified. This ensures that a quality inspection of the generated products is achieved which is as integrated as possible. Different production requirements make it necessary that all recipes (color compositions) are centrally stored on a separate storage medium or PC / server and that they can be called individually.
New color compositions are mixed in the production development and integrated into the running process as and when required.
According to the parameter sets, which are transferred to the controller via the HMI operator panel, the controller processes the values and transfers them to the corresponding valves, drives, Level, etc.
Control requirements
According to the parameter sets, which are transferred to the controller via the HMI operator panel, the controller processes the values and transfers them to the corresponding valves, drives, Level, etc.
HMI requirements:
1-The HMI is to be realized by a Touch screen.
2-Color inspection and analysis and converted to recipe done automatic by the machine.
3-Manual mode with recording for the mixing process
The following operating options are to be available:
1-Option to change all recipe parameters.
2-Option to change all recipe parameters
3-Writing the data records into the controller
4-Reading the data records from the controller
5-Exporting data records
6-Importing data records
7-Adding new data records
8-Deleting existing data records
9-Display of the current process progress (displaying the representation of the filling process).See More
