National foreword This standard includes safety requirements. This document (EN 12268:2014) has been prepared by Technical Committee CEN/TC 153 “Machinery inten-
5、ded for use with foodstuffs and feed” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-18-02 AA Fleischverarbeitungs-maschinen of Section Nahrungsmi
6、ttel- und Verpackungsmaschinen. Representatives of manufacturers and users of food processing machinery, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery D
7、irective”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the
8、 European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been publi
9、shed as the corresponding DIN EN or DIN EN ISO Standards with the same number. Where the International Standards referred to are not also DIN ISO Standards with the same number, there are no national standards available. Amendments This standard differs from DIN EN 12268:2011-02 as follows: a) Claus
10、e 1: the scope has been clarified; a new clause has been added to describe the machine types; requirements have been transferred to the appropriate clauses; b) Clause 2: normative references have been updated; c) Clause 3: terms have been partly revised (e.g. fixed feed table); consistent use throug
11、hout the standard; d) Clause 4: new presentation in a table; e) Clause 5: new subclauses have been added in Subclause 5.2 according to the danger zones; more detailed requirements have been specified for product pusher, protective rail and blade guide; f) Clause 6: the verification list has been upd
12、ated; g) Clause 7: completion of Subclause 7.2 with all information referred to in Clause 5, now including the operator training; Subclause 7.3 now contains the marking; h) annexes: the former Annex C “Common hazard” has been deleted and the text has been transferred to the appropriate clauses; i) f

36、 12268:2014(E)5 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document. When provisions of this type C standard are different
37、 from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. DIN EN 12268:2015-01EN 12268:2014 (E) 6 1 Scop
38、e 1.1 General This European Standard specifies requirements for the design and manufacturing of band saw machines as described in 1.2 (see Figures 1 to 5). The machines covered by this European Standard are used to cut: bones; fresh or deep frozen meat with or without bones; fresh or deep frozen fis
39、h, natural or in fillets; deep frozen block food products; fresh or deep frozen vegetables; other products such as pork fat or similar products. The band saw machines covered by this European Standard do not include band saw machines for processing wood and similar materials which are covered by the
40、 EN 1807 series. Band saw machines for domestic use are not included in this European Standard. This European Standard is not applicable to band saw machines which were manufactured before its date of publication as EN. This European Standard deals with all significant hazards, hazardous situations
41、and events relevant to band saw machines, 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 t
42、ransport, assembly, commissioning, operation, cleaning, use, maintenance, decommissioning, dismantling, disabling and scrapping of the machine. This European Standard covers the following types of machines: band saw machines designed as table-top machines with and without base; band saw machines des
43、igned as floor-type machines with and without castors. 1.2 Description of various machine types 1.2.1 General Band saw machines consist of a machine casing, a fixed feed table or a sliding feed table, a roller conveyor or conveyor belt, a product pusher, a height-adjustable protective rail, a top an
44、d a bottom wheel, a saw blade, an upper and lower blade guide, a blade tensioning device, a drive and electrical components, depending on machine type. This standard does not deal with machinery with automatic loading/unloading systems (e.g. automatic conveyors). DIN EN 12268:2015-01 EN 12268:2014 (
45、E) 7 On floor-type band saw machines, the product to be cut is placed by hand onto the fixed feed table or sliding feed table and pushed against the cutting zone of the saw blade by means of the product pusher or the rear table wall on the sliding feed table or by means of the roller conveyor or con
46、veyor belt and sawed. 1.2.2 Type A Band saw machine with a fixed feed table and a non-detachable, movable product pusher: Maximum cutting height SH 250 mm.

47、aw machine type A with product pusher Location: table top Figure 2 Band saw machine type A with product pusher Location: base 1.2.3 Type B Band saw machine with a fixed feed table, a protective rail and a maximum cutting height 60 mm shall be provided. The portioning plate may be designed to be tilt
48、able and removable. It shall be possible to change the saw blade without removing the product pusher. DIN EN 12268:2015-01 EN 12268:2014 (E) 14 In case of having a combination of rail and pusher the requirements of type B shall be considered. Dimensions in millimetres Key 1 saw blade A1distance betw

This can be achieved e.g. by the following measures: A non-detachable blade guide and a height adjustable protective rail shall be provided (see Figures 3, 4 and 8). A maximum distance of 6 mm shall be installed, either between product pushe
