Tannery machines - Reciprocating roller machines - Safety requirements

This European Standard specifies safety requirements for all the phases of the life of a machine listed in 5.3 a) of EN ISO 12100-1:2003".
Reciprocating roller machines are machines used for the processing of animal hides and skins. They have a reciprocating opening and closing motion of the feed rollers or conveyors which, if required, may also reverse their direction.
This standard covers the following reciprocating roller machines (see figures 1 to 13 for typical configurations and annex D for descriptions):
a) Buffing machines (see figures 1a and 1b)
b) Polishing machines (see figures 1a and 1b)
c) Ironing machines (woolskins and fur) (see figures 2a and 2b)
d) Carding machines (see figures 3a and 3b)
e) Shearing machines (woolskins and fur) (see figures 4a and 4b)
f) Cylinder universal staking machines (see figures 5a and 5b)
g) Setting-out machines (see figures 6a and 6b)
h) Dewooling machines (see figures 6a and 6b)
i) Scudding machines (see figures 6a and 6b)
j) Unhairing (dehairing) machines (see figures 6a and 6b)
k) Sammying machines (see figures 6a and 6b)
l) Cylinder ironing machines (see figures 7a and 7b)
m) Cylinder staking machines (see figures 8a and 8b)
n) Fleshing machines (see figures 9a and 9b)
o) Demanuring machines (see figures 10a and 10b)
p) Wet wheeling machines (see figures 11a and 11b)
q) Shaving machines (feed-out) (see figures 12a and 12b)
r) Shaving machines (feed-in) (see figures 13a and 13b)
It takes account of intended use, foreseeable misuse, component and systems failure.
This European Standard is not applicable to reciprocating roller machines which are manufactured before the date of its publication as EN."
This European Standard provides provisions for the reduction of noise emission at the design stage (see 5.2.4 and Annex A). However, it does not provide a noise test code for the determination by measurement of noise emission values for the machines it covers. Without such a code the manufacturer cannot fulfil his obligation to provide the noise emission values of the machines put on the market."
All the significant hazards (see Clause 4) are dealt with in this European Standard except the following:"
Dust, smoke and vapour emissions (see Annex B);
Fire (see Annex C).
For these hazards general guidelines are proposed in !normative annexes". Designers and
manufacturers shall verify directly that the methods adopted to reduce these hazards have been successful.

Strojarski stroji - Valjčni stroji - Varnostne zahteve

Ta evropski standard določa varnostne zahteve za vse življenjske faze stroja, navedenega v 5.3 a) EN ISO 12100-1:2003.
Valjčni stroji so stroji, ki se uporabljajo za obdelavo živalskih kož. Podajalni valji ali transportni trakovi se odpirajo in zapirajo recipročno, po potrebi pa lahko smer tudi obrnejo.
Ta standard zajema naslednje valjčne stroje (glej slike od 1 do 13 za značilne konfiguracije in dodatek D za opise):
a) brusilni stroji (glej sliki 1a in 1b);
b) polirni stroji (glej sliki 1a in 1b);
c) likalni stroji (za kože z volno in krzno) (glej sliki 2a in 2b);
d) stroji za mikanje (glej sliki 3a in 3b);
e) stroji za striženje (za kože z volno in krzno) (glej sliki 4a in 4b);
f) cilindrični univerzalni stroji za raztegovanje (glej sliki 5a in 5b);
g) stroji za količenje (glej sliki 6a in 6b):
h) stroji za odstranjevanje volne (glej sliki 6a in 6b);
i) stroji za glajenje (glej sliki 6a in 6b);
j) stroji za odstranjevanje dlak (glej sliki 6a in 6b);
k) sušilni stroji (glej sliki 6a in 6b);
l) cilindrični likalni stroji (glej sliki 7a in 7b);
m) cilindrični stroji za raztegovanje (glej sliki 8a in 8b);
n) stroji za odstranjevanje mesa (glej sliki 9a in 9b);
o) stroji za odstranjevanje gnoja (glej sliki 10a in 10b);
p) stroji za mokro brušenje (glej sliki 11a in 11b);
g) stroji za strganje (na izhodu) (glej sliki 12a in 12b);
r) stroji za strganje (na vhodu) (glej sliki 13a in 13b).
Ta standard upošteva predvideno uporabo, predvidljivo napačno uporabo ter okvaro komponent in sistemov.
Ta evropski standard ne velja za valjčne stroje, proizvedene pred datumom, ko je bil objavljen kot EN.
Ta evropski standard navaja določbe za zmanjševanje emisij hrupa pri stopnji načrtovanja (glej točko 5.2.4 in dodatek A). Ne navaja pa preskusne kode hrupa za merjenje vrednosti emisij hrupa za stroje, ki jih zajema. Brez take kode proizvajalec ne more izpolniti svoje obveznosti za navedbo vrednosti emisij hrupa strojev na trgu.
Ta evropski standard obravnava vse pomembne nevarnosti (glej klavzulo 4), razen naslednjih:
emisij prahu, dima in hlapov (glej dodatek B);
požara (glej dodatek C).
Splošne smernice za te nevarnosti so navedene v normativnih dodatkih. Projektanti in proizvajalci morajo neposredno preveriti uspešnost sprejetih metod za zmanjševanje teh nevarnosti.
