This program is operated by touch screen
and PLC control. Through weighing sensor, weighing controller, liquid level
sensor, pass in and out barrel sensor, limit sensor, door switch sensor, pass
to PLC through module. By the working instructions of the touch screen, the PLC
is delivered by the motor, and the weighing controller controls the filling
capacity. The output signal controls the working procedure. Complete automatic
filling, load cap and capping.
Control principle:
Full set of equipment is divided into
bucket conveyor, filling machine, conveyor, capping unit, finished product
conveyor four parts.
the whole set of equipment will to be
finished automatically from the positioning transfer pail, weighing filling and
capping except manual load pail on conveyor. Weighing system adopts gross
weight type, which makes measurement and re examination more convenient and
accurate, and has many functions, such as automatic tracking, correcting
filling precision, etc. The horizontal conveying system of the filling machine
adopts frequency conversion regulator and the speed controller to ensure the
material does not overflow during the process. By way of filling nozzle go down
to filling to avoid material spills. Vacuum suction device is also available to
ensure a clean countertop. When the bucket changed, the initial height of the
filling system can be adjusted by rotating the hand wheel, and the utility
model can be adapted to various bucket types, and the adjustment process is
simple and reliable.
The touch screen is used in the operating
system to realize full automatic and manual control. Can be selected on the
screen and setting weight, so that the operation is simpler and more intuitive.
At the same time, it can display the current running state, accumulative
output, accumulation alarm, low pressure alarm and other faults and display.
