Original Instructions
5.4 Mechanics
5.4.1 Tyres
The driving wheels are fitted with rubber tyres in the size 4.00 x 6
on rims made in one piece with the toothed wheel in a synthetic
material.
Stand wheels are solid rubber tyres on synthetic rims.
5.4.2 Nozzle Special corrosion-resistant long distance pencil jet nozzle with 1/4"
pipe thread and 14 mm hexagon. The nozzle opening is 1.5 mm.
5.4.3 Materials The MULTICLEANER is mainly produced of corrosion-resistant,
synthetic and rubber materials.
In a few cases it has not been possible to produce or require parts
made of above-mentioned materials. Instead we have chosen other
but also very durable parts to diminish wear and corrosion.
These materials have been chosen to protect the robot from the
extremely tough environment (water and ammoniac fumes) in which
it has to work and thus to avoid increased risk of stoppage because
of corrosion, unnecessary wear etc.
5.4.4 Ultrasonic sensors The MULTICLEANER features two ultrasonic sensors on the right
side of the robot, which are used for regulation of direction and
distance.
The sensors emit/pick up sound impulses and the controller then
calculates the distance to the inventory in the aisle. It measures the
time from the emission of the sound impulse till the pick up of the
echo.
This information is then converted to a real distance.
If an echo has not been picked up within a short time because of
missing inventory sides, the control will activate the alarm.
If the ultrasonic sensors are covered by a lot of dirt, the reliability
may be affected. Note! Check that the two ultrasonic sensors are
clean before starting the robot and that the gates into the individual
pens are closed.
5.5 Components in the
water supply
5.5.1 Water filter
Before the water valve there is a water filter with a rustproof strainer
with a mesh size of 0.25 mm, which strains impurities out before
they reach the water valve. The water filter should be cleaned/
checked each 100 operating hours.
5.5.2 Water valve On the water inlet side a 24 VDC, solenoid valve is mounted. This
valve is open or closed depending on the working phase of the ma-
chine. The function of the valve is to disconnect the water supply
when the arm turns or the robot is in stand-by mode.
The valve is closed when the there is no voltage to the coil.
5.5.3 Flow switch In extension of the water valve a flow switch is mounted, which
continually checks the water supply. In case the water supply fails, if
for instance the water hose comes off, a signal is transmitted to the
control, which shuts down the MULTICLEANER and activates the
alarm. Thus it is avoided that the pump unit breaks down. The flow
switch has been adjusted from the factory.
