Metal ring inputting and outputting device

Abstract

A metal ring loading and unloading apparatus is capable of loading and unloading a metal ring quickly and highly accurately for increased efficiency. The metal ring loading and unloading apparatus has a moving unit (41) slidably movable along a rail (48) which extends from a loaded ring placement unit (8) to an unloaded ring placement unit (11). On the moving unit (41), there are mounted a loaded ring delivering unit (9) for holding and delivering a metal ring (W) on the loaded ring placement unit (8) and an unloaded ring delivering unit (10) for removing the metal ring (W) from support rollers (3, 4) and delivering the metal ring (W) to the unloaded ring placement unit (11). The loaded ring placement unit (8) has a pressing unit for radially pressing the metal ring (W) to deform the metal ring (W) into a substantially elliptical shape. The loaded ring delivering unit (9) has a loaded ring gripping unit (26) for gripping the metal ring (W) deformed by the pressing unit. The unloaded ring delivering unit (10) has an unloaded ring gripping unit (53) for gripping the metal ring (W) under its own recovering resiliency produced when the support rollers (3, 4) move toward each other. The unloaded ring placement unit (11) has a releasing unit for releasing the metal ring (W) from the unloaded ring gripping unit (53).

Description

[0001] This application is a divisional application, the international application number of the original application is PCT / JP01 / 08106, the application date is September 18, 2001, and the invention name is: metal ring insertion and removal device. technical field [0002] The invention relates to a metal ring putting in and taking out device for putting an elastic metal ring into and supporting it on a supporting roller, and taking out the metal ring supported on the supporting roller at the same time. Background technique [0003] For example, in a belt used to transmit power in a continuously variable transmission, a laminated ring in which a plurality of metal rings are laminated is used in order to integrate a plurality of elements stacked in a ring shape. The metal rings that make up this kind of laminated ring are formed by cutting a cylindrical roller into circular sheets at regular intervals to form endless belts, and then put them into a rolling machine or a perimet...

AI Technical Summary

Problems solved by technology

[0006] However, when using a roller compactor or a perimeter straightening machine for the prescribed processing, since the insertion and removal of the metal ring must be done manually, the work efficiency is very low and it is not suitable.

[0007] Also, due to the elasticity of the metal ring, when the metal ring is supported on two rollers, it is difficult to maintain a slightly elliptical shape corresponding to the supporting shape of the two rollers

In addition, the metal ring taken out from the two supporting rollers, due to the release of the stretched state formed by the two supporting rollers, makes it recover rapidly from a slightly elliptical shape to a slightly circular shape, and may accidentally touch other parts and cause damage metal ring

Therefore, the operation of putting in and taking out the metal ring is extremely troublesome.
