Interlocking devices

DEFINITION
Emergency blocks, are switches that cause the machine to stop immediately when
activated, and do not allow the machine to start again until the emergency has been re-
activated, and the re-set button (on control panel) is pressed.
For instance, end of stroke micro-switches are considered interlocking devices because
they are used to detect when any mobile safety guard is opened. The photocells are also
considered interlocking devices. On the machine the following end of stroke micro-
switches are found and are used to stop the machine:
• a micro-switch "a" stops the machine when the steel grill (3) that cover the stainless
steel hopper is opened. The micro-switch is activated by a cam attached to the shaft on
which the grill pivots and is under the machine body;
• a micro-switch "B" stops the machine in case a tray is not found in the deposit position
above the conveyor-belts;
• a micro-switch "C" stops the machine in case the plate is extracted from its working
position;
• a photocell "D" is located at the tray infeed to stop the motion in case its reading area
was interrupted;
• two photocells "E" have been fitted at the tray outfeed to stop the motion in case their
reading is interrupted.
