If the hopper can be removed without using tools:
a) it shall be interlocked; or
b) it shall be detected that it is at its right position by means of safety systems.
The interlocking device or detecting device shall be actuated before the opening gap between the fixed
and the movable parts exceeds 20 mm.
The metering rollers and every other moving part inside the hopper shall stop in ≤ 1 s.
4.2.1.5.2 Hazard due to cleaning of the other parts of the deposit unit
It is permitted to fix the parts of the deposit unit, other than the hopper, with means which do not require
tools for being removed.
Any part of the machine, other than the deposit unit parts, which prevents access to danger zone shall be:
— fixed with means which require tools for being removed;
or
— interlocked; in this case, the following requirements shall be fulfilled:
— the interlocking device shall control the stop of every moving part of the machine when the
clearance between the part being removed and any other nearby part does not exceed 10 mm;
— the stopping time shall be ≤ 1 s.
4.2.2 Zone 2: Access to the space between the deposit unit and the table
4.2.2.1 General
The manufacturer shall provide guides on each side of the table (see Figure 4), whose function is to avoid
unwanted movements both vertically and horizontally perpendicular to the direction of advancement of
the tray.
If the guides are adjustable, they shall fulfil the following requirements:
— they shall be horizontally adjustable to adapt to different sizes of the trays which can be used with
the machine, as declared by the manufacturer in the instructions (see 6.3);
— they shall be vertically adjustable to adapt to different heights of the trays which can be used with
the machine, as declared by the manufacturer in the instructions (see 6.3), considering a vertical
deformation (loss of flatness) of them ≤ 3 mm;
— for removing a horizontally adjustable guide it shall be possible to remove it only using tools and the
fixing means shall remain attached to the guide or to the machine.
For fixing the vertically adjustable guides it is permitted the use of means which do not require tools for
being removed.
It is permitted the adjustment of the guides without using tools.
NOTE In general, it is not necessary to get close to the dangerous area. In some cases, the operator might be
induced to hold the tray still because, due to the viscosity of the deposited dough on the tray, it could detach slightly
from the table when the table descents or deposit unit ascends. It does never happen when there is no relative
movement between the table and the deposit unit (for instance, when the wire cutting system, if provided, is used).
In the instructions the manufacturer shall (see 6.3):
— give information about the prohibition of using the machine for production without the guides
assembled and correctly adjusted;
— give information about how to adjust correctly the position of the guides;
— specify that only plane trays can be used with a maximum deformation ≤ 3 mm for the flatness;
— give information about the prohibition of using sheets of baking paper on the trays; on the other
hand, as it is well known and therefore reasonably foreseeable that the operator can place a baking
paper sheet on the bottom of the tray, information shall be provided in the instructions about suitable
products to be sprayed or spread on the tray or other systems to keep the sheet sufficiently adhering
to the bottom of the tray, pointing out that in any case the best solution for the safety is to use non-
stick trays.
