3.1 Performance 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 oper-
ating 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 operating
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.
Owing to the modular design and the wide number of standard components, the conveyor system can be
perfectly suited to any premises. You can use a lot of other peripheral devices and optional accessories with
the conveyor system that will make your work processes significantly easier. Components suitable for use
with foodstuffs and easy-to-clean construction ensure the highest hygienic standard.
3.2 Intended Use
The conveyor system is mainly designed to hold up gastronorm and euronorm trays. Any other use is not in-
tended.

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 model of the conveyor system is mounted on stands. A combination of wall and
base installation is possible.
A mobile model 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 to be used as store place in the base. Put the elements on to the long rails fit-
ted in the base of the conveyor system. 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 rocker limit switch (SGR and SPV)
The rocker limit switch is pivot-fitted on the frame surface between the finger-protection elements
Loads press down the rocker limit switch as a result of which an electrical signal is generated which
stops the belt movements. 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. The belt automatically
starts to run again once the rocker limit switch is released.
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. The effect of a non-transparent part e.g. a tray moving across the photo cell is to trigger a
signal which stops the belt movements. The belt automatically starts to run again once the photo cell
is released.

Description and Technical Data Chapter 3
Appliance Description Page 15
Round Belt Conveyor System
4330054_A2 SGR | SPV
Pneumatic foot switch (SPV only)
The foot switch allows to start and stop the conveyor belt. It is used in addition to the operating ele-
ments on the control panel.
Patient card drawer (SPV only)
The patient card drawer holds up patient cards and can be quickly and completely taken out without
any tools. It is fitted under the conveyor belt at the beginning of the belt system. Do not exceed the
maximum load of 25 kg.
Rotary table (SPV only)
Use the rotary table that is fitted on the beginning of the belt at about 250 mm from the front side to
keep your records or other information. The rotary table and the support tube rotate independently of
each other. Rotate the rotary table only when there are no objects on its surface and there are no
people around it. Do not exceed the maximum load of about 5 kg. The rotary table is delivered disas-
sembled. To assemble the rotary table, insert the support tube into the plastic part.
Hinged board (SPV only)
The hinged board is an additional storing shelf and is fitted flush at the end of the belt. You can fold
up the board lifting it slightly up and raising it to an angle of 90°. There should be no objects on the
board when folding it down. Do not exceed the maximum load of about 10 kg, otherwise there is a risk
of damage to materials.
Curved elements (SGR)
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. Where the straight belt is continued, the trays
are supported by plastic runners. Appropriately adapted stainless steel tray guiding rails undertake
guidance at the sides.
Tray guiding rails for bends (only SGR)
Tray guiding rails are needed to correctly guide trays in curved sections. 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 with the structure and are for mounting the tray guiding rails. As the tray guiding rails are in-
serted in blocks, they ensure a high degree of stability. The tray guiding rails in the sets are appropri-
ately bent to fit.
Light curtain (SGR only)
The light curtain prevents the further movement of loaded trays beyond the end of the belt. Place the
light curtain at the middle, about 350 mm from the end of the belt.
Light curtain 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 opposite and flush on the pan edging bar.
The optics are adjusted on the basis of consultation. The minimum and maximum height above the
edge is 5 mm and 20 mm respectively.
Sorting bridge (SGR only)
The sorting bridge is used for a 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 model without a chute but with a sound absorbing panel attached at the bottom can be fit-
ted 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. Mounting of the tilt switch on the belt casing is such that the front edge is posi-
tioned 250 mm from the edge of the belt. This makes it possible to put the belt directly at the wall,
thus saving space. The tilt switch is always to be positioned in front of the switch box. Otherwise, bot-
tles 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
into the corresponding collecting carriages. The device with magnet and internal conveyor belt is hori-
zontally mounted above the conveyor belt. Any other objects projecting above are not to be detected
by the cutlery pickup device. They must be removed before lifting.
Queue-clocked circuit (SGR only)
The queue-clocked circuit is needed for continuos tray removal The round belt conveyor runs at a

SGR | SPV 4330054_A2
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 selection switch is arranged on
the switch box.
Hand-in area with collecting pan trough (SGR only)
The collecting trough collects any spilled liquids in the hand-in area, thus stopping the round strap
belts being dirtied. 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.

sioning
4.1 Transport
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 the 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
the transport vehicles may be used that are approved for the weight of the appliance.
According to the valid purchase contract, the scope of delivery is specified in the shipping documents at-
tached to the delivery item.
4.2 Assembly
DANGER Hazardous electrical voltage
The electrical voltage may be considerably dangerous to limb and life of per-
sons and lead to injuries.
All work on electrical installations or operating materials should only be car-
ried out by a certified electrician or by trained personnel under supervision
and monitoring of a certified electrician according to the certain electro-
technical regulations.
DANGER Defective Emergency Stopper
An instance of fault e.g. from defective contactors may cause the drives to
continue to run even after the emergency stopper 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 in excess of 6m
The following section only applies to conveyor systems in excess of 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).
There must be a possibility after consultation to connect the conveyor system to the mains.
We do not recommend dowelling the conveyor system with the floor of the premises because of the
moisture barrier layer existing in the most of cases.

The user of the conveyor system must take the following measures beforehand to ensure the safety of the
operating staff:
Specify the field of application and draw up corresponding safety instructions.
Instruct the operating staff in safety.
Give the operating staff training.
Mark hazardous areas.
4.2.1 Assembling the segment
ATTENTION Injury to persons and/or damage to property
Parts of the conveyor system may topple over during assembly and cause
injuries and damage.
The segments should always be mounted by 2 people. Get some help, if need
be.
ATTENTION Damage to property
Do not place the segments onto the floor with the surface facing down, since
they can get scratched or damaged.
Use a suitable piece of material to place the segments.
INFO Disposal of packing material
The packing consists of recyclable materials and can be disposed of appro-
priately. Thereby, the different materials are to be separated and disposed in
an environmentally compatible manner. In any case, the local bodies respon-
sible for disposal are to be involved for this purpose.
Proceed as follows when mounting the segments of the conveyor system:
Remove the segments from the transport packaging and arrange in the position envisaged.
When assembling begin with the end of the belt. When doing this, place the first segment on the
marked position.
Screw the segment under the next part of the belt. When doing this, the first person holds the seg-
ment while the second person is pushing the next part of the belt on to the connector of the segment
the first person is holding.
Put together the edges of the segments so that they are flush and screw them together from below.
Continue with the assembly as described above.
Check again the inclination and align the conveyor system on the screw feet horizontally with the
spirit level until it is level. Normally, the height is 900 mm.

4.2.2 Assembling the round belt
ATTENTION Risk of injury from snapping round belts
Tensioning may cause the round belt to snap and shoot upwards.
Work together with another person. Hold the ends of the round belt as near as
possible to the point of connection. Wear protective goggles and safety gloves
during the entire assembly procedure.
NOTE Required tools
Fitting and welding the round belts is only to be done with the HUPFER® tool
which is provided. The welding and tightening set from HUPFER® is included
in delivery for assembly purposes.
The welding and tightening set consists of the jockey for tightening the round
belts, welding tongs for keeping the round belt ends together, the welding iron
for welding together the round belts and the mitre cutter.
NOTE Smooth round belts
Only smoothly mounted round belts ensure that the trays are reliably and
properly transported on the conveyor.
Make sure that the round belts do not get twisted when carrying out the op-
eration.
Step 1: Fitting the round belts
To fit the round belt, proceed as follows:
Keep hold of one end of the round belt, unravel it from the drum and cut to the required length.
Remove the cover plate at the beginning of the belt system and guide the round belt across the alu-
minium disk downwards through the belt casing and across the conveyor roller.
Guide the round belt to the end of the belt system and upwards over the conveyor roller and alumin-
ium disk through the belt casing. The two ends of the round belt are now now opposite each other on
the surface of the structure.
Step 2: Stretching the round belt
ATTENTION Risk of injury from snapping round belts
Tensioning may cause the round belt to snap and shoot upwards.
Work together with another person. Hold the ends of the round belt as near as
possible to the point of connection. Wear protective goggles and safety gloves
during the entire assembly procedure.
NOTE Operating instructions -Jockey
The jockey is needed to tension the round belts. The operating instructions of
Greifzug GmbH are enclosed with the jockey.
Read through the operating instructions before beginning with the tensioning
operation. Pay particular attention here to the sections on ’Safety instructions’,
’Description of the appliance’ and ’Appliance use’.
