EN 13871:2014 (E) 6 1 Scope 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.

Fixing systems for fixed guards or for demountable parts of the machine casing (i.e. designed as fixed guards) shall remain attached to the guards or to the machine when the guards are removed. 5.2.2 Measures on cubes cutting machines with a forward feed plunger, a lattice and sickle blade and loading by hand 5.2.2.1 Zone 1 – Feed intake chamber (magazine) with forward feed plunger, feed intake hopper with closure gate, feed conveyor, nip roller Access shall be prevented either by a movable guard (e.g. restrictor plate, lid), interlocked according to 5.2.1 or shall be secured by a non-detachable restrictor plate or adequate safety distances and design as described in 5.2.3.3. Taking into account the specific technical constraints (high loading frequencies), the movable guard (lid) can be designed as a control guard according to EN ISO 12100:2010, 3.27.6. Openings in the guard (e.g. restrictor plate, lid) may have a diameter D

52 mm for L ≥ 120 mm. The dimensions and arrangements of the guard shall be according to Figure 12. Fastening of the non-detachable restrictor plate shall be according to EN 953.

EN 13871:2014 (E) 19 5.2.2.2 Zone 2 – Rotating cutting tool and lattice Access to danger points on cutting tools and lattice shall be prevented by enclosing guards in compliance with EN 953. The enclosing guards shall be designed to prevent penetration by ejected parts as e.g. blades. Movable enclosing guards over danger points shall be interlocked according to 5.2.1. The blade housing and blade guard shall be designed to prevent penetration of flung parts (e.g. blades or parts of blades). Excepted are the outlet, inl
