Description of BS EN 13871:2014 2014

1.1 General

This European Standard covers cube cutting machines (see Figure 1 to Figure 6 and Figure 12 to Figure 18) and specifies requirements for the design and manufacture.

The machines covered by this European Standard are used to size reduce fresh meat, meat products and products of the same kind (e.g. fish, vegetables and cheese) by cutting in a cutting chamber.

This European Standard deals with all significant hazards, hazardous situations and events relevant to machines, appliances and machinery, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

This European Standard deals with the hazards which can arise during all the lifetime of the machine, including the phases of transport, assembly, operation, maintenance, dismantling, disabling and scrapping of the machine.

This European Standard is not applicable to cubes cutting machines which are manufactured before the date of publication of this document by CEN.

1.2 Types of cube cutting machines covered by this standard

This European Standard covers the following types of cubes cutting machines:

• cubes cutting machines with a forward feed plunger, a lattice and a sickle/multi-segment blade with loading by hand (see Figure 2);

• cubes cutting machines with a forward feed plunger, a lattice, a sickle/multi-segment blade, a feed intake hopper and a loading device (see Figure 1);

• cubes cutting machines with a rotating cutting tool, a sickle/multi-segment blade and a feed conveyor (see Figure 3 and Figure 5);

• cubes cutting machines with a rotating cutting tool and centrifugal force loading (see Figure 6);

• cubes cutting machines with or without integrated conveyor systems.

1.3 Machine construction

Cubes cutting machines are constructed of a machine frame, a feed intake chamber/magazine, a forward feed plunger or nip roller, a lattice or a rotating cutting tool, a sickle/multi-segment blade, an associated drive and electrical, hydraulic and pneumatic components, depending on machine type.

Cubes cutting machines in the scope of this European Standard may be equipped with:

• a lid over the feed intake chamber/magazine;

• a transfer car for the sickle /multi-segment blade, cutting blade and lattice;

• a loading device;

• a feed conveyor.

1.4 Intended use

The intended use (as defined in EN ISO 12100:2010, 3.23) of cubes cutting machines as dealt with in this document is described in 1.1.

The product to be cut is fed manually or by the loading device/feed conveyor into the feed intake chamber. The product is fed to the cutting unit by the forward feed plunger and/or by the nip roller or by centrifugal force and size reduced.
