Title:
COUPLING DEVICE AND SPINNING PULLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/074323
Kind Code:
A1
Abstract:
Provided is a coupling device in which a coupled state is achieved by inserting a male coupler into a female coupler, wherein the operation required to detach the male coupler from the female coupler is simplified. The female coupler (74) comprises: an outer cylindrical member (91); an inner cylindrical member (92) which is provided inside the outer cylindrical member (91) so as to be capable of relative movement in the axial direction with respect to the outer cylindrical member (91), and which is pressed in by the male coupler (73) when the male coupler (73) is inserted; and a spring (93) which impels the inner cylindrical member (92) from the base side to the tip side of the female coupler (74). As a result of a drive unit moving the female coupler (74) to a coupled position, the male coupler pushes the inner cylindrical member (92) towards the base side against the impelling force of the spring (93), thus achieving a coupled state, the coupled state is maintained by maintaining the female coupler (74) at the coupled position, and the coupled state is released by returning the female coupler (74) to the initial position thereof.
