Stroji in obrati za proizvodnjo, obdelavo in predelavo ravnega stekla - Varnostne zahteve - 3. del: Rezalniki

Ta standard vsebuje varnostne zahteve za načrtovanje in postavitev strojev z enim premičnim mostom za rezanje ravnega stekla, ki deluje tako, da zarezuje na steklo, položeno na vodoravno podporo. Ta standard zajema transport stekla na stroju. Ta evropski standard obravnava velike nevarnosti, nevarne situacije in primere, ki se nanašajo na stroje za rezanje ravnega stekla, kadar se uporabljajo kot predvideno in pod pogoji napačne uporabe, ki jih razumno predvidi proizvajalec (glej Klavzulo 4). Ta evropski standard opredeljuje ustrezne tehnične ukrepe za odpravo ali zmanjševanje tveganj, ki nastanejo zaradi velikih nevarnosti med usposobitvijo za zagon, obratovanjem in vzdrževanjem. Nevarnosti zaradi hrupa se ne štejejo za velike.

In this case, the time-dependent cut-out shall be monitored, e. g. electronically according to Annex G (normative). Where category 0 is used, mechanical brakes shall be applied. 5.1.19 At the control panel and at each working side of the cutting table, where the squaring and the take-off is done by operators, emergency-stop equipment in accordance with EN ISO 13850:2008, 4.4.3, shall be provided within reach of the operator. The emergency stop shall function according to 5.1.18. Provisions shall be made to ensure that emergency stopping can also be effected on other machines linked to the operation of the cutting machine when this would otherwise introduce a significant hazard. The emergency stop (manually operated actuator) devices shall be situated at the height of the table. 5.1.20 After a stop command has been initiated by protective devices described in 5.2 and 5.3, a restart shall be possible only after a switch (a manual reset device) conforming to the requirements of EN ISO 13849-1:2008, 5.2.2, has been actuated at a place from where there is a good view of the danger zone. This switch shall be mounted in such a way that its operation from inside the danger zone is impossible. 5.1.21 All electrical equipment shall conform to the requirements of EN 60204-1 with regard to the protection against electrical shock (see EN 60204-1:2006, Clause 6)." 5.2 Additional special safety requirements for flat glass cutting tables where access is not intended NOTE For a synopsis of possible methods of safeguarding according to 5.2 and 5.3 (in respect of the operation mode and the speed of the cutting bridge) see annex J (informative). Flat glass cutting machines where under normal operating conditions access by persons is not intended shall be provided with safety measures to avoid the risk of impact and the risk of crushing and drawing-in of the arm by the bridge or its drive shaft.
Dangerous movements shall have stopped before the danger zone can be reached by any person. ! 5.2.1 A 1,4 m minimum height fixed perimeter fence in accordance with Annex A (normative) shall be provided at each side of the machine. Access shall be provided by movable interlocking guards (see EN 953:1997, 3.3 and 3.5) to both longitudinal sides of the table or photo-electric guarding with one photo-electric sensing unit according to EN 61496-1:2004, type 4, and CLC/TS 61496-2:2006, Annex B (normative) or Annex C (normative)." 5.2.2 However, if there is no free space to use method 5.2.1, fixed distance guards close to the danger zone shall be provided at each side of the machine in accordance with annex D.
Access shall be provided by movable interlocking guards with guard locking (see 3.2, 3.2.2, 3.3 and 3.6 of EN 953:1997) to both longitudinal sides of the table in the area of the ground (zero) position of the bridge. 5.2.3 The small sides of the cutting machine shall be guarded by fixed distance guards in conformity to EN 953 or photoelectric guarding, or adjacent bordering components.
Where adjacent bordering components are to be used details of proximity and safety attributes shall be included in the Information for use. ! 5.2.4 The control system associated with the interlocking of guards shall be in accordance with the requirements of EN ISO 13849-1:2008, performance level d. Annex H (informative) gives an example for an interlocking guard without guard locking incorporating two cam-operated position detectors according to EN 1088:1995, Ann
