This document covers cube cutting machines and accessories.
1.1 This document specifies requirements for the design and manufacture of cubes cutting machines (see Figures 1 to 6 and 12 to 18).
The machines covered by this document are used to size reduce fresh meat, meat products and products of the same kind by cutting in a cutting unit.
This document deals with all significant hazards, hazardous situations and events relevant to machines, appliances and machinery, when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4).
This document deals with the hazards which can arise during commissioning, operation, maintenance and de-commissioning of the machine.
This document is not applicable to cubes cutting machines which are manufactured before the date of publication of this document by CEN.
1.2 This document covers the following types of cubes cutting machines:
-- Cubes cutting machines with a forward feed plunger, a lattice and a sickle blade with loading by hand (see Figure 2)
-- Cubes cutting machines with a forward feed plunger, a lattice, a sickle blade, a feed intake hopper and a loading device (see Figure 1)
-- Cubes cutting machines with a rotating cutting tool, a multi-segment blade and a feed conveyor (see Figures 3 and 5)
-- Cubes cutting machines with a rotating cutting tool and centrifugal force loading (see Figure 6)
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 or multi-segment blade, an associated drive and electrical, hydraulic and pneumatic components, depending on machine type.
Cubes cutting machines in the scope of this document may be equipped with:
-- a lid over the feed intake chamber/magazine;
-- a transfer car for the sickle blade/multi-segment blade, cutting blade and lattice;
-- a loading device;
-- a feed conveyor.
