<P>PROBLEM TO BE SOLVED: To provide a controlling apparatus for a sealing apparatus capable of immediately detect pinching of a hand and a foreign article and biting of a dividedly packaging sheet when they occurs and avoiding a large accident and a failure, and a dividedly packaging machine equipped with this. <P>SOLUTION: The controlling apparatus for the sealing apparatus is constituted so that when an electric current is detected by an electric current detector 4, the first comparator 5 switches a state to an H state, and when it is not detected, the first comparator 5 switches the state to an L state, and when the electric current detected by the electric current detector 4 is a more excessive electric current value than a specified value, the second comparator 6 switches the state to the H state, and when it is an electric current value which does not exceed the specified value, the state is switched to the L state. A condition judging instrument 7 stores combinations of respective states of the first comparator 5 and the second comparator 6 on every specified time as a preceding state. When the first comparator 5 is in the H state and the second comparator 6 is in the L state in the preceding state, and furthermore when both the first comparator 5 and the second comparator 6 are in excess loading states being the H states in the next state, a roller 2 is reversely rotated by a roller reversely rotating circuit 8. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
