3.1Performance Description
The conveyor system is designed to convey trays loaded with crockery. The conveyor system conveys the
trays to the following work step. Depending on the type used, the conveying system conveys either clean
trays loaded with portioned meals or trays containing dirty crockery.
The crockery return belt system (SGR) is used mainly to hold up Gastronorm and Euronorm trays and to
clear away continuously and quickly trays with dirty crockery, cutlery, glasses and napkins. Members of the
operating staff clear away the trays loaded with dirty crockery items that are conveyed to the washing area.
The food distribution belt system (SPV) is used mainly to hold up Gastronorm and Euronorm trays and to
load continuously and quickly trays with crockery, cutlery, glasses and napkins. Serving devices and operat-
ing staff that stays at the conveyor system load trays and serve portions on crockery items. To serve meals
up to the guest area, you can use other peripheral devices at the end of the belt.
Thanks to the modular design and the wide number of standard components, the conveyor system can be
perfectly suited to any premises. Peripheral appliances and optional accessories can be added in order to
substantially streamline operations. Components suitable for use with foodstuffs and easy-to-clean construc-
tion ensure the highest hygienic standard.
3.2 Proper Use
The conveyor system is mainly designed to hold up Gastronorm and Euronorm trays. Any other use is not in-
tended.
The crockery return belt system (SGR) is used to hold up and to convey trays with dirty crockery, cutlery,
glasses and napkins.
The food distribution belt system (SPV) is used to hold up and to convey trays with portioned meals, clean
crockery, cutlery, glasses and napkins.

3.4.3 Equipment and Optional Accessories
You can install and fit the conveyor system with optional accessories in various ways:
§Types of installation (SGR and SPV)
The standing alone design of the conveyor system is mounted on stands. A combination of wall and
base installation is possible.
A mobile design includes 2 swivel casters per belt system leg. All the swivel casters have total brakes
for safety reason.
§Plastic shelves in the base (SGR and SPV)
The plastic shelves are designed as storage shelves in the base. Put the elements on to the long rails
fitted in the base of the conveyor belt. The shelves can be used even at maximum load (up to 100
kg/m) for longer time at the temperature between -30°C and +70°C. The plastic shelves can be easily
removed to clean the appliance.
§Mechanical limit rocker switch (SGR and SPV)
The pivotable limit rocker switch is installed on the surface of the structure at the end of the belt be-
tween the finger protection elements. When loads are applied, the limit rocker switch is pressed down
and an electrical signal is created which stops the belt movement. The switch mechanism is protected
on all sides against ingress of liquids and dirt particles. Cleaning is only to be done when the belt is
switched off. After releasing the limit rocker switch the belt will start moving automatically.
§Photo-electric limit switch (SGR and SPV)
The photo-electric limit switch is installed in the frame surface at the end of the belt between the
round belts. If a non-transparent item, e.g. a tray, moves across the photo cell, a signal is triggered
which stops the belt movements. The belt automatically starts to run again once the photo cell is re-
leased.

Curved elements are for connecting straight segments. They are available in standard 45° and 90°
angles. Acute angles in excess of 135° are provided with their own drive. These curved elements fea-
ture a single belt running centrally across guide rollers. The trays are supported by plastic sliding rails
in continuation of the straight belt. Appropriately adapted stainless steel tray guiding rails undertake
guidance at the sides.
§Tray guiding rails for bends (SGR only)
Tray guiding rails are required for guiding the trays correctly in bends. Transporting trays in bends
without tray guiding rails will not work as they may get turned round, twisted and jammed. A set con-
sists of plastic blocks, stainless steel tray guiding rails and fastening material. The plastic blocks are
bolted onto the structure and are for holding the tray guiding rails. As the tray guiding rails are insert-
ed in blocks, they ensure a high degree of stability. The tray guiding rails in the sets are appropriately
bent to fit.
§Light barrier (SGR only)
The light barrier prevents the further movement of loaded trays beyond the end of the belt. Place the
light barrier at the middle, about 350 mm from the end of the belt.
Light barrier and reflector are mounted at the end of the belt as a height restrictor (crockery detector)
and fitted in stainless steel covers. They must be fastened facing each other and flush on the bar of
the edge of the well. The optics are adjusted on the basis of consultation. The minimum and maxi-
mum height above the edge is 5 mm and 20 mm respectively.
§Sorting bridges (SGR only)
The sorting bridge is used for safe storage on the opposite belt casing. You can fold it up by lifting it
slightly up and raising it to an angle of 90°. The unfolded sorting bridge is flush with the belt casing.
The hinged design without a chute but with a sound absorbing panel attached at the bottom can be
fitted on the belt upon agreement. The maximum load of the sorting bridge is 25 kg.
§Tilt switch (SGR only)
The tilt switch prevents any further movement of loaded trays beyond the end of the belt. With auto-
matic stacking, a tilt switch as a height restrictor or crockery detector is fitted at the end of the belt in
the sorting area.
The height restrictor can be universally adjusted to all the usual crockery heights. The overall height is
190 mm +/- 15 mm. The tilt switch is mounted on the belt structure in such a way that the front edge
is positioned at a distance of 250 mm from the edge of the belt. This allows the belt to be positioned
directly against a wall, which saves space. The tilt switch is always to be positioned in front of the
switch box. Otherwise, bottles on the tray would not be recognized in time and might collide with the
underside of the switch box.
§Magnetic cutlery pickup device (SGR only)
The magnetic cutlery pickup device lifts, transfers and ejects magnetically detectable cutlery items in-
to the corresponding collecting carriages. The device with magnet and internal conveyor belt is hori-
zontally mounted above the conveyor belt. All other items must not be caught by the cutlery pickup
device and must be removed before the pickup process is initiated.
§Queue-clocked circuit (SGR only)
The queue-clocked circuit is needed for continuous tray removal. The round belt conveyor runs at a

constant speed in the tray hand-in area of the guest room. Behind the hand-in section there is a band
segment with separate motor and round belt. When a tray leaves the hand-in area, the belt moves on
by a little over one tray length. The following belt (behind the hand-in area) is thus loaded with a tray
in cycles. A photo-electric switch in the casing acts as the signaller. If required, the queue-clocked cir-
cuit can be switched off. With the standard operating elements, the selector switch is arranged on the
switch box.
§Input area with collecting pan (SGR only)
The collecting pan collects spilled liquids in the input area and therefore prevents contamination of the
round belts. No tool is needed to remove the perforated plates for cleaning the collecting pan.
§Intermediate segment (SGR only)
The intermediate segment for the sorting area with one-sided structure taper, smooth casing surface
and centre base is needed for more comfortable working. Thanks to the structure taper, work can be
carried out right next to the belt casing and objects can be easily handed over to the other side.

Service
4.1Transport
The delivered conveyor system with the length of up to 6 m is completely assembled, wired and set so that it
is ready for operation.
Conveyor systems with a length of more than 6 m will be delivered segments that have to be assembled.
When loading, use only hoists and load lifting devices approved for the weight of the conveyor system. Only
transport vehicles that are approved for the weight of the appliance may be used.
The scope of delivery is specified in the shipping documents in accordance with the valid purchase agree-
ment and included with the delivery item.
4.2 Assembly
DANGER Hazardous electrical voltage
Electrical current can pose a considerable threat to life and physical well-
being and may lead to injuries.
Only an electrician or instructed staff under the guidance and supervision of
an electrician may work on electrical systems or operational equipment; they
must comply with the electrical industry rules while doing so.
DANGER Defective emergency stop
In case of fault, e.g. from defective fuses, the drives may continue to run even
after the emergency stop has been pressed.
ATTENTION Injury to persons
Only two people are to carry out mounting the segments and the round belts.
Wear protective goggles and safety gloves when putting down and welding
the round belt.
INFO Conveyor systems longer than 6 m
The following section only applies to conveyor systems longer than 6 m which
need not be delivered and mounted as a unit.
Check the premises before setting up the conveyor system. Flaws can be detected and improved at an early
stage. Observe the following points:
§The floors in the premises where the appliance is to be set up must be level and correspond to the
required load-bearing capacity of 196 N/m² (20 kg/m²).
§Electrical connections for the conveyor system must be in place as agreed.
§We do not recommend attaching the conveyor system to the floor of the premises with plugs because
of the moisture barrier layer that exists in the most cases.
