DSP LASER
14 DSPLSR01EN
DSP LASER is connected to the press command circuit in such a way that, if intercepted, it
stops the mobile table only during the fast approaching phase (from PMSM/PMS to PCV).
In this way, it ensures the safety of the operator against the mechanical dangers (due to the
approaching movement of the punch to the die) in the area of the dies:
•
squashing and/or cutting danger between the punch itself and the die or the piece in
work.
During the working phase (speed lower than or equal to 10 mm\sec), going from PCV to
PMI, the system is inhibited and does not protect the operator against the danger described
in the previous point and from the dangers relevant to the movement of the piece in working
under the pressing strength of the punch:
•
danger of squashing among the tools, between the piece and the upper tool or
between the piece and the mobile table;
•
danger of crash of the piece (bending movement).
In the same way, during the opening movement of the tools, the protection system is
inhibited. The physical arrangement of the detection area, placed under the upper tool,
makes the system cannot give protection against the dangers due to opening movement,
among which:
•
danger of squashing between mobile table and fixed parts of the press-brake;
•
danger of crash due to the fall of the worked piece.
9.2. Foreseen use of the DSP LASER device
The DSP LASER device has been designed to create, by means of the laser beam emitted
by the transmitter and picked up by the receiver, a detection area (volume) for the
protection of the operator who enters in it.
Warning :
DSP LASER provides protection to the operator only stopping the
movements in progress of the upper table. Then, it cannot be used in
case of projection of material. Then pay special attention to the
choice of the material to work, of the tools and to the possible
presence of foreign bodies within the tool movement area. The
transparent tools entering the detection area are not detected.
The device has been designed and manufactured in order to ensure protection to the
operator, who accesses in front of the die area of a bending press-brake, against the
dangers due to the movement of the mobile table during the high-speed downstroke phase.
The interception of the DSP LASER detection area by the operator during the fast closing
movement stops the movement of the mobile table before the tool fixed to it can reach the
operator, who however must know the risks relevant to the work on this type of press-
brakes. Anyway, the device does not replace the necessary training of the personnel and
information about the residual risks highlighted in chp. 11
Residual risks .
The correct use of the device foresees the mechanical installation of the transmitter and of
the receiver on the upper table in such a way that the detection area is located near the
punch. In case of machine with closing from above, the system moves with the mobile table.
The electrical installation must be based on the detection of the continuity/interruption of the
detection area which determines the state ON / OFF of two electrical signals made available
by DSP LASER and which can be used for the control of the dangerous movements of the
press-brake.
