Europa, Tecno OMNI CONTROL CHECKWEIGHER
EUROPE (Western and Northern)
The checkweigher is part of a transporting line
that controls objects of any type and shape.
Going through the weighing surface takes a certain time.
Although very short, this time is enough
for the scales to take on a position
that is proportioned to the weight of the product.
When it is about to leave the scales,
the object meets the beam of light that crosses the conveyor.
This way overshadowed,
the fototransistor commands the electric circuit
to carry out immediately the weight checking.
This weight value is then compared with the two values,
inferior and superior, fixed as the acceptance limits.
The checkweigher then according to this result accepts
or rejects the weigh,
consequently let it proceed undisturbed,
or divert and reject it. When this latter happens,
the object can be diverted towards left
or right depending on the type of weight defect (surplus or lack).
