Hanel
Rotomat
The Principle/Technical Data
The Principle
The compact design of Hanel's Rotomat vertical carousels means
vast storage capacity on minimal floorspace. The Hanel Rotomat
works on the principle of rotational conveyance, i.e. the goods
are brought to the operating personnel and not vice versa.
Structural Design
Self-support steel plate housing, comparable to the cellular structure
used in aircraft construction. Environmentally friendly powder
coating is used, together with shock-proof and impact-resistant
stove enamels which are not only highly elastic, but also non-toxic
and physiologically harmless. The outer surfaces are painted in
a leather texture finish. The retrieval opening, which is about
600 mm wide, can be closed by a centrally-parted sliding door.
A weight counterbalancing system makes it easy to open and close
the door. The sliding door and the lower maintenance hatch are
locked by simultaneously activated safety locks. The worktable
is of durable stainless steel. The safety factor of the suspension
chains is 5:1 for dynamic loads and 7:1 for static loads. The
carrier-frames are suspended according to the sliding carriage
principle and are supported by 4 levers on 4 rollers at both ends.
The sliding carriage is designed to safely absorb transverse loads,
thus significantly reducing wear.
Drive System
The standard drive system comprises pole-changing 400V three-phase
motors (other voltages and special frequencies can be supplied
as options) and self-locking worm gear, allowing gentle but powerful
acceleration and braking under varied load conditions. A die-cast
aluminum gear housing has been selected based on weight considerations.
Soft start and soft stop is accomplished by utilizing 2-speed,
3-phase AC motors.
Spring pressure safety brakes operate when the
motor switches off and are released electro-magnetically when the
vertical carousel is put into operation. Manuel winding cranks
are also provided as standard. The twin-motor design used with
these wider vertical carousels (3,270 mm width) means less wear
and smoother operation compared to a single-motor design.
Safety Devices
If anything is placed in the access opening accidentally the Hanel
safety rocker, at the top and bottom of the retrieval opening,
interrupts the safety circuit and an air gap opens for the user.
This reduces the risk of damage to goods and increases user safety.
The Hanel safety rocker permits relatively level
access to the stored goods. In addition to this safety mechanism,
2 to 4 sets of self-monitoring photoelectric sensors are installed
for the protection of personnel and goods. These devices are continually
self-testing, not only when the vertical carousel is in motion,
but whenever power is switched on. This means that if a light
barrier fails, all vertical carousel movements are reliably stopped
or inhibited. All safety switches are designed to ensure automatic
opening.
Control Units
State-of-the-art microprocessor control units take only seconds
to guide the required article to the viewing and retrieval point
gently and quietly by the shortest rotational route. The electrical
control unit is accessible from the front and is accommodated
in a special control panel above the retrieval opening for easy
maintenance.
The keyboard is in the
central of the control
panel and can be easily reached. A keyboard that can be moved
to the side or stowed beneath the worktable can be supplied as
an option. Hanel has a variety of control units in its range.
(For information on these ask for our special brochure on microprocessor
and EDP controls).
The features of the intelligent microprocessor
control systems include: warehouse management with recording of
article numbers, parts lists, inventory control for one or more
vertical carousels; optional list processing with allocation of
free storage positions, re-order point, journal logging, etc;
computer link and use of other peripheral devices such as printers,
barcode readers, scales; data protection with read-only memories,
such as EEPROMs.
Imbalance Load Indicator
System (Optional)
Hanel's automated load imbalance device - UL 2 - not only indicates
when the load in the vertical carousel is unevenly distributed,
but gives recommendations for storage and retrieval movements.
The UL 2 system has its own computer which makes this possible. |
