PURPOSE:To transfer a work with a fixed pitch in the desired direction at the proper speed in such a way that a trough is actuated at different speeds in two forms by means of change-over of driving mechanisms and detecting mechanisms of a motor and a speed reduction apparatus under successive operation of a motor and a reduction gear in one direction. CONSTITUTION:After a motor 7 has been started, when a disc 28 of a first detecting mechanism S1 is set to turn at the point (a) on the basis of the connecting condition in a low speed side mechanism L in the process in which a driving shaft 13, a body of revolution 22, and an interloking body 34 makes low speed actuation, a high speed side mechanism H is connected by means of excited actuation of an electromagnetic clutch 14 in such a way that a first detector 30 is controlled by means of a dog 29 just before the point b. On the basis of this condition, high speed actuation is initiated in such a way that the disc 28 is moved from the point b to the high speed process. And, just before the point (a), a second detector 31 is controlled by means of the dog 29, and the clutch 14 is changed over to OFF, so that the driving mechanism is changed over from the high speed side H to the low speed side L, and the interlocking body 34 is driven thereafter like a crank with a different speed. |
