PURPOSE:To make it possible to separate a work without fail irrespective of its moving speed by subjecting a front pawl and rear pawl to a sequence operation with the simple reciprocating motion of an actuator for rocking a cam. CONSTITUTION:Two slidable sliders 2, 2' are arranged while putting between said sliders a double wing-shaped cam 3 taking a rotary shaft 4 as its center. When one circumferential part 3a of the cam 3 engages with the recess of the slider 2, the other circumferential part 3a' is made not to engage with the recess 2'a' of the slider 2'. A case 1 suppots a rotary shaft 4 rotatably provided with grooves in which the sliders 2, 2' are slidable, and pawls 6, 6' are mounted on the sliders 2, 2'. When the cam 3 is rocked, the slider 2 moves below. And the front pawl goes down between the works 7a, 7b, and when the cam 3 is further turned, the rear pawl 6' shifts upward, allowing the work 7a to be released and a row of left works to be hindered by the front pawl 6. |
