8-THEORY OF OPERATION

8.1 Description of the Working Cycle

After having closed the top flaps of the carton, the operator pushes it under the top infeed end

in order to avoid the opening of the top flaps. Further pushing causes the two top and bottom belts to drive the box through the taping heads which automatically seal the top and bottom seams.

The carton is then expelled on the exit conveyor.

8.2 Definition of Running Mode

The case sealer 700r has only one (automatic) oper- ating mode with:

-The EMERGENCY STOP BUTTON unlocked

(Figure 8-1)

-The main start switch “ON” (I)

(Figure 8-2)

8.3.1 Normal Stop Procedure

When the main switch is turned OFF (O), the machine stops immediately at any point of the working cycle. The same thing happens in case of electrical failure or when the machine is disconnected from the mains.

8.3.2 Emergency Stop

The LATCHING EMERGENCY STOP BUTTON is located on the top center of the machine
