Abstract
PURPOSE: To enable the operation of machine tools to be interruped in the case of failure in performing cut-off by providing a material detector, synchronizing signal generator, memory circuit and discrimination circuit in the machine tools which work the materials being subsequently and continuously fed.
CONSTITUTION: At the time when the material being continuously fed goes from U to D, the material is brought to the specified position at the point t1 and a sensor SA becomes L and the output Q1 of a memory circuit EF1 becomes L, thus it is stored that the material has been supplied to the specified position. Next, the input of a gate G1 is L and the output H at the point of t2, when the output of G2 does not change and the output Q2 of a memory circuit FF2 maintains the H state to prevent the relay from operation, from which it is checked that the feed is normal and the signal for inconvenience is not emitted. When the material having undergone working is cut off at the point of t3, the sensor SA becomes H and SB L and resetting of FF1 is accomplished to permit continuation of the work.
