PURPOSE:To perform insertion correctly and promptly and make labor saving and high efficiency in the work by grasping steel pipes and guiding simultaneously synthetic resin pipes thereinto and by the use of guides for loose insertion. CONSTITUTION:Steel pipes A are mounted on a lower guide 1 and fixed thereon by means of a magnet 3. The top ends of vinyl chloride pipes B are guided through the tapered guide surface 1a, 2a of guides 1, 2 by means of a pusher 6 on lower delivery rolls 5 and transported by the pusher up to the position where the top end thereof comes near to the steel pipes A. In the next place, the upper guide 2 is pressed to the upper surfaces of the steel pipes by means of an air compression cylinder 4 and at the same time the vinyl chloride pipes B become a state of loose insertion with respect to the upper and lower guides. By driving the lower delivery rolls, the vinyl chloride pipes are inserted into the steel pipes and the support table 9 of the air compression cylinder 4 is made capable of coming up and down in accordance with the diameter of pipes. In this fashion, insertion can be performed correctly and promptly and thus labor saving and high efficiency in the work can be made thereby. |
