Automated Candle Manufacturing Line Training System

A first part allows to manufacture the paraffin pastilles with or without colour and a second, part can offer the possibility to crimp and to cut the wick to the desired length and to assemble the whole in a capsule and to package the finished product in boxes. The finished product is perfectly usable.

• A MAGELIS interactive console display, communication with PLC over serial line, UNI-TELWAY protocol, allowing the input of system parameters,
• 1 control cabinet on module 1,
• 2 control cabinets on module 2,
• A PC supervisor with Modbus/Jbus protocol, connected to the PLC via an RS232-RS485 converter and a PCMCIA network card on the PLC.

The supervision allows the display of state, of the system defaults. It also serves to the supervision and monitoring with several screen displays for the user with in particular the sequential function charts in real time.

• Entirely protected with a safety guard with opening on the front side.

• Module 1: L x l x h = 800 x 1950 x 2000mm.
• Module 2: L x l x h = 800 x 2200 x 2000mm.

The cycle is described via sequential function charts and the Gemma (Studying guide of the on/off modes). The different actions are described as tasks, regrouped in a tasks sequential function charts at the level of the program structure.

• Industrial Maintenance, Functional analysis of the system, Automatism, Dialogue between console display - PLC and supervision - PLC, - Industrial Mechanics.

• Exploitation of production line: - with the help of the interface man / machine, - And of the supervision,
• These 2 components allow to register the parameters necessary to the working of the automated system ; numbers of manufactured candles, the defaults, lack of raw materials, as well as to inform the user on the state of the chain at any times.

• - Study of the technological choices chosen for the operative part according to some characteristics (speed, course, storage capacity, cycle time.

• - Dialogue man/machine with the dialog MAGELIS control display and the supervision.
• - Visualization of the defaults, and of the state of the machine at any time (synoptic of the different parts,sequential function charts, real time GEMMA ).
• - Visualization of the state of the sensors and motors.

• Normal working mode (F1).
• Random step-by-step mode (F4).

• Information exchange between the control display, the PLC, the supervisor.

• Identification and segmentation of the automated system in tasks.
• Research of the antecedences between the tasks.
• Development of the sequential function charts.

• Optimisation of the rates.
