The new PLC can control all machine parameters with following advantages:
Estreme flexibility
It permits to interface with the selector and screw feeder according the type of product you are assembling; it allows to make several adjustments too: bowl vibration, screw shooting time and bowl vibrating time after screw shooting
Multi-functionality
With the new PLC it can be used semi-automatically (using air and electric screwdrivers) and automatically (using air and electric motors)
Expandability
This PLC can be expanded by increasing the number of inputs/outputs depending on your technical/production requirements.
Integrability in automated production systems
It can be interfaced with other ‘master’ PLCs and it is easy to use with existing automatic processes
Process reliability
The production cycle can be monitored and diagnosed as it can be interfaced with operator panels, via the connector for digital I/O for feeder control (indicator and monitoring devices LEDs, PLC, Traffic lights…)
Easy and quick adjustment of the machine parameters
Machine parameters can be adjusted directly via the PLC’s functional keypad (and not on a portable PC as is the case for other feeders on the market)
The new selector guarantees:
Higher speed and productivity
130 screws/minute (with average size screws)
Extreme reliability
Even when the NCA is subject to logistic shifts, the selector’s calibration parameters do not change thanks to its new more solid and compact design
The new optical fibre sensor assures:
High and uninterrupted productivity
It makes sure no screw gets stuck in the selection duct (the optical fibre detects the screw after a length of time established by the PLC and activates a solenoid valve produces a jet of air that gets rid of any surplus screws)
The new screw shooting unit allow:
A optimal speed of the screw
The screw is shot inside a closed chamber and there is no longer any dissipation of compressed air; the power is concentrated entirely on speeding up the screw’s path. This speed quickens the whole system significantly and process productivity as a result.
The new feeding hoses make the passage of the screw easier and quicker with non chance of getting stuck.
Other advantages
Good capacity of the bowl diameter for working autonomy
Volumes have been reduced for easy inclusion in the production areas
The new system is designed to allow easy maintenance and component replacing: in fact, the exterior structure is easily and quickly removed to access all its inside parts
The new transparent and bigger cover allows a better view of the inside without having to open the machine
New materials used for improved soundproofing
The whole feeding system has been standardised with Festo components for a better quality and quicker supply
