Chapter 8 Markings
Article 112
The safety device for the power press machine shall be marked the following items:
1. manufacture number.
2. manufacturer.
3. manufacture date.
4. applicable the press machine type, capability, stroke( except the two-hand control safety device), the number of strokes per minute( except the two-hand control safety device and the photoelectric safety device) and die sizes.
5. The two-hand control safety device or the photoelectric safety device shall be marked in accordance with the following provisions:
(1) for the safe-one-stroke-two-hand control safety device: the time(Tl, in milliseconds) that hands releasing from the operating portion of that device to the starting action of the protective stop mechanism.
(2) for the two-hand start safety device: the maximum time( Tm) that hands releasing from the operating portion to the slider of the applicable press machine reaching the lower dead center , in millimeters
(3) for the photoelectric safety device: the time that fingers intervening the sensing zone of that device to the starting of the protective stop mechanism, in millimeters.
(4) the stop time(Ts, in milliseconds) of the applicable press machine: the time that the protective stop mechanism starting action to the slider stopping, in milliseconds. But that marked the maximum stop time(Tl + Ts) being exempt from separately marking Tl and Ts.
(5) for the safe-one-stroke- two-hand control safety device or the photoelectric safety device: according to the set stopping time in the preceding subparagraph.For the two-hand start safety device : in accordance with the the maximum time separately corresponding to the safe distance set in the preceding subparagraph(2). for two- hand control safety device: the distance between the operating portion and the hazard zone, in millimeters.for photoelectric safety device: the distance between the optical axis and the hazard zone, in millimeters.
6. The photoelectric safety device, in addition to the marking in the preceding subparagraph, shall mark the followings:
(1) the effective distance: refering to the distance that the emitter and receiver can effectively function, in millimeters.
(2) the protective height for the applicable press machine, in millimeters.
7. The laser-sensitive safety device for the press brake, in addition to the marks in the preceding subparagraph 1 through 3, shall separately mark the followings:
(1) the tim ethat from the protective stop mechanism enacted to the slider stopping when the laser shaded, in milliseconds.
(2) the distance between the optic axis of the press brake and the hazard zone , in millimeters and that being corresponding to the time in the subparagraph 7(2).
(3) the effective distance that the laser optical axis can effectively function, in millimeters.
8. The push-out safety device, in addition to the marks in subparagraph 1 through 4, shall separatley mark the maximum amplitude of the push-out arm, in millimeters.
Article 113
