PURPOSE: To improve the workability of tray supplying work by adjusting the moving speed of a parts housing tray in multiple stages by means of a moving speed adjusting device when the trays is moved forward by one stroke of a pushing-out device which pushes out a desired tray to a mounting table from a tray supply magazine. CONSTITUTION: A desired parts housing tray 21 is pushed out to a mounting table 26 from a tray supply magazine 20 by means of a tray pushing cylinder 22. When the tray 21 is moved forward by one stroke of the cylinder 22, the moving speed of the tray 21 is adjusted in multiple stages by means of a moving speed adjusting device 45. The device 45 is composed of position switches 24 and 25, a position switch 27 which is provided at a desired position within the moving stroke of the rod 23 of the cylinder 22, and a speed controller communicating with the cylinder 22 through a communicative passage. The speed controller communicated with a controller provided in an operation box which controls the opening/closing operations of solenoid valves communicating with the controller. |
