3 General description and intended use
3.1 General description
Round-belt conveyors and used to return
dirty tableware.
The linear attachments of the round belts
leave almost the whole of the conveyor sur-
face available.
This method of returning dirty tableware is
especially preferential as it only allows the
return of trays. Individual items of tableware
(plates, cups, cutlery, bottles) cannot be
deposited and therefore cannot fall off the
conveyor later in the journey, e.g. on the
corners.
This means that tableware return functions as a high level.
Round-belt conveyor technology can conquer any possible type of corner.
Differentiated speeds and the necessary spacing carry the trays safely and securely
around the corner in the centre of the conveyor.
High, sturdy tray guides ensure that any tableware which is stacked tightly does not fall
off at the corners, as well as safely and securely steering the trays.
MEIKO vertical conveyors are the perfect solution for running vertical systems. The
MVF-G and MVF-P provide:
A continuous, fluid transition from horizontal to vertical movement
Excellent stability for items of tableware
The MEIKO infeed and outfeed system ensures gradual braking and smooth start up
even at high rates of throughput (up to 30 trays per minute).
3.2 Intended use
DANGER!
This conveying system is only intended to transport trays carrying tableware, no other use
is permitted.
This conveying system is solely intended for use in a work environment.
This conveying system is approved for loads of up to 5 kg/m unless a contrary agreement
has been reached.
Max. speed is 20 m/min.
9750655
7 / 34
The approved tray dimensions stated in the chapter on "Technical specifications" must be
adhered to, as must all other technical specifications without exception.
If you do not operate this round-belt conveyer system in line with its intended use, safe
operation of the machine cannot be guaranteed!
The operator, not the manufacturer, is responsible for any injury or material damage aris-
ing from improper use.

6 General safety instructions
6.1 Operator’s duty of care
CAUTION!
The round-belt conveyor has been constructed based on a risk analysis and after careful
selection of the applicable harmonised standards as well as additional technical specifica-
tions. It is therefore state-of-the-art and provides maximum safety.
However, safety can only be guaranteed during operation if all necessary measures are
taken. The operator of the machine has an obligation of care to ensure that these
measures are planned for and also to check that they are correctly implemented.
After installation, commissioning and handing over of the round-belt conveyor to the cus-
tomer/operator, no modifications may be made (e.g. electrical system or location). Modifi-
cations to the round-belt conveyor, and in particular technical modifications carried out
without the manufacturer’s written authorisation, or any modifications carried out by unau-
thorised persons, will lead to the complete loss of any guarantee claims and will invalidate
any liability for the product.
The operator must ensure in particular that...
... the round-band conveyor is only used as intended.
In case of other use or operation, damage or risks may arise for which we accept no liability
(see the section on "intended use").
8 / 34

parts other than original spare parts.
CAUTION!
... only appropriately qualified and authorised employees may use, maintain and repair the
installation.
CAUTION!
… personnel is regularly trained in all questions relating to occupational safety and envi-
ronmental protection and, in particular, the staff is familiar with the operating instructions
as well as the safety instructions that they contain.
CAUTION!
... the installation is only operated in perfect, operationally efficient condition, all protection
devices and cover panels are installed, and, in particular, that the safety systems and
switch elements are regularly checked for their operational efficiency.
CAUTION!
... the required personal protective equipment is made available to and used by mainte-
nance and repair personnel.
CAUTION!
... he operating instructions are always in a legible state, complete and available at the
installation's location of use.
CAUTION!
... none of the safety and warning notices attached by the operator are removed and that
they are legible.

Special functions: queuing function
The queuing function is turned on at quiet times for the pot wash.
When the queuing function is turned on, it is not necessary for a person to stand by the
tableware clearing section and continuously clear tableware.
The queuing function is turned on by pressing the
toggle switch next to the on and off switches on
the control panel.
Turn toggle switch for queue operation.
The first section of the conveyor Section I (tray in-
feed station) remains in operation.
The trays are conveyed as far as the queuing func-
tion-light barrier/light key at the end of section I.
When a tray activates the light barrier/light switch, the next conveying system, section II,
switches on. If the tray has passed through the light barrier/light switch, the section II con-
veying system stops. This creates a row of trays at narrow intervals.
If the first tray in the queue section activates the height limiting light barrier at the end of
the conveying system, the whole installation shuts down and a horn signal sounds. This
signal can be turned off by switching the queuing function to continuous operation.
