Automatic Process With Conveyors Description and Specifications for Lab Tenders
Automatic Process With Conveyors.
The automation process with conveyor has
been designed and carried out with industrial criteria and
components, to be a high level equipment in an automation
laboratory for the study of:
• Electropneumatics
• Electronics
• Electrical engineering
• Mechanics
• Automation with PLC
The system mainly consists of two
independent units with conveyor belt that together can
reproduce a complete machining cycle. The first unit develops
the following functions:
• Taking of the machining pieces from a vertical
magazine
• Detection of the machining pieces
• Pieces conveyance toward the conveyor unit 2, by means
of “Pick and Place” unit provided with suction cup The second conveyor unit carries out:
• Machining pieces detection
• Pieces deposit in final tool magazine
The components present on the system are:
• Electropneumatic (single- and double-acting cylinders,
solenoid valves, depression unit)
• Electrical (single-phase asynchronous motors, relays)
• Electronic (inductive, capacitive, magnetic sensors)
• Mechanic (motion reducing systems)
Each unit has a control board with front panel reporting the
electrical diagram of the contacts and the actuators. On the
panel, there are connectors for connection to the control
system. In this way, the system can be
considered an application of the trainers with PLC . The I/O interfacing of the automation process with conveyor to the trainers is made via accessory connection terminals. The control of the whole system is performed by the user from a pushbutton board connectable to the PLC. This includes the pushbuttons, with signaling lamp for START, STOP, EMERGENCY and others which function can be defined by the application. In this way, it is possible to develop a wide range of programming examples for the machining cycle,
without changing the structure of the system.
The development of the exercises is supported by the
theoretical-experimental handbooks provided with the
automation process with conveyor .
