Abstract

PURPOSE:To allow tubings to drop parallelly and neatly for accommodation by installing a swinging buffer plate suspended in a frame body in which tubings on a rack roll and drop by own weight, and thereby preventing bending of a tubing to be cast into a cradle. CONSTITUTION:A tubing accommodation part is limited to a V-shaped small area by rotating a bottom plate 60. When supplied from a sorting rack 4, each tubing P rolls and drops by its own weight to run against a buffer plate 65, which is installed suspended on the tubing supply side of a frame body 32 in such a way as free to swing oscillatively. Thus the moving speed is dampered. At the same time, its direction is restrained to the longitudinal direction of the frame body 32, and the tubing falls onto the bottom plate 60. This bottom plate 60 is inclined and accommodates tubings P in alignment oriented in the same direction as the longitudinal axis of the frame body 32. With increase of tubings accommodated, the bottom plate 60 is turned in horizontal plane to increase the accommodation area. This serves reduction of the falling speed to provide lowered noise generation and prevention of damage to tubing P, and further, aligned accommodation of tubings enables effective operation of bundling.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to an apparatus for sorting and storing pipe bodies such as temporary pipes used in construction and investment work by length.
-Relating to a cradle IC for extracting a tube body.

There is a structure shown in No. 4. These tube classifications are used to remove tubes stored in the device #C, and sort the tubes by length.
ζFor sorting, the elevating cradle installed on the exit side of the shelf is stopped at the required position to receive the tubes.

Next, a method is adopted to lower the cradle to the ground and eject it.The problem that the invention is trying to solve is the above sorting, in which the whole tube body is transferred from the shelf into the cradle. It rolls and falls from G, but at this time the tube is in a free state, so it rebounds when falling,
Alternatively, due to relocation along the inside of the cradle, etc., each tube body may not be handled manually, but may be stored in a disordered state, tilted in the vertical or longitudinal direction. This causes bending of the tubular body, and also causes a large amount of noise when falling, and also causes a problem in bundling, as the weight of the tube increases.

One object of the present invention is to prevent the tubes inserted into the cradle from being damaged by bending or the like, and to ensure that the tubes fall in a parallel orderly manner and are stored therein.
