PURPOSE:To make the sensing operation due to the vertical movement of a sensor more accurate, by providing the sensor, which senses the passage of rolled materials, in a part different in level where the lower stream side is slightly higher than the upper stream side for rolling. CONSTITUTION:A fruit 1 supplied from a conveyor is rolled on a bottom face 3 of a shoot 2 and is supplied to a lower hopper or the like. In the course of this supplying, a sensor 5 is moved vertically by the contact with the fruit 1 and senses every fruit 1 to calculate the number of transferred fruits. When the fruit is placed just on the sensor 5, the closing state of a microswitch is kept. The sensor 5 is returned to the upper limit position completely to break the microswitch. Even if the rolled fruit 1 is rolled along the slope, the time when the contact of the fruit 1 placed on the bottom face 3 in a lower stream side (b) acts upon sensor 5 is shortened because the lower stream side (b) is higher in a part 4 different in level. |
