1.1 General This European Standard covers portion cutting machines and accessories. This European Standard does not apply to automatic industrial slicing machines (see EN 16743:2016) and band saw machines (see EN 12268:2014).This European Standard defines requirements for the design and manufacture of portion cutting machines. The machines covered by this European Standard are used for continuous portioning of fresh, smoked or frozen meat with and without bones or of similar products by separation by means of a blade. 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 commissioning, operation, maintenance and decommissioning of the machine. The European Standard does not deal with the specific hazards of loading devices. This European Standard is not applicable to portion cutting machines which are manufactured before the date of publication of this document by CEN.
1.2 Types of machinery This European Standard covers the following types of machinery: - Portion cutting machines with manual loading (see Figure 1); - Portion cutting machines with automatic loading (see Figure 2).
1.3 Machine construction Portion cutting machines depending on the construction consist of: machine housing (machine frame), fixed or moving product bases, automatic or manually operated grippers, hold-down unit, blade housing, blade, discharge device, associated drives, electrical, hydraulic or pneumatic components. Portion cutting machines in the scope of this document may be equipped with the following auxiliary components:
- loading aid; - discharge conveyor belt;
- laying unit;
- measurement or scanning devices;
- sorting station (e.g. rocker, pusher); - movement devices (e.g. castors).
1.4 Intended use The intended use (as defined in EN ISO 12100:2010, 3.23) of portion cutting machines as dealt with in this document is described in 1.1. The product is manually placed on the product base or automatically fed to the product base with a loading device. The product is supplied to the blade by automatic or manually operated grippers or conveyor slide or belt and the cutting process begins. The portion falls onto a discharge conveyor or a laying unit.
