Abstract
Provided is a cap detachment device including a plug, a cap part, and a cap tool that detaches the cap part from the plug. The cap tool has a holding part that holds the cap part, a grip part gripped by a robot holding the cap tool, a support part attached to the grip part and supporting the holding part movably along the cap axis, a spring that applies, to the holding part, pushing force in a direction coming close to the plug along the cap axis, and a rotary shaft that rotates the holding part about the cap axis, and the rotary shaft rotates the holding part holding the cap part about the cap axis and thereby detaches the cap part from the plug.
Claims5
A cap detachment device comprising:
- a plug secured in an opening provided in a top face of a liquid storage container, the plug having a liquid channel extending in a first axis and a groove extending annularly about the first axis;
- a cap part having an insertion part and configured to seal the liquid channel, the insertion part being inserted in the groove and extending cylindrically about the first axis;
- and
- a detachment mechanism configured to detach the cap part from the plug,
- wherein a first thread part is formed to the insertion part,
- wherein a second thread part configured to be engaged with the first thread part is formed in the groove,
- wherein the detachment mechanism has
- a holding part configured to hold the cap part,
- a grip part formed tubularly along a second axis and gripped by a gripping mechanism configured to grip the detachment mechanism,
- a support part attached to the grip part and configured to support the holding part movably along the second axis,
- a pushing part formed of an elastic member that expands and contracts along the second axis and applying, to the holding part, pushing force in a direction coming close to the plug along the second axis, and
- a rotary part configured to rotate the holding part about the second axis, and
- wherein the rotary part rotates the holding part holding the cap part in a predetermined direction about the second axis to detach the cap part from the plug.
