Abstract

Providing a seal member taking-out device which can successfully take out a larger number of seal members. The seal member taking-out device includes a shaft member, a cylinder member, a moving member, and a taking-out member. The shaft member is columnar or cylindrical. The cylinder member is cylindrical and the shaft member is inserted through the cylinder member so that the cylinder member is movable in a direction of a central axis of the shaft member. The cylinder member is shorter than the shaft member and extends in the direction of the central axis of the shaft member. The moving member moves a plurality of seal members stacked on the shaft member and the cylinder member, in a direction of a distal end of the shaft member. The taking-out member takes out the seal members from the distal end of the shaft member.

First claim

1 . A seal member taking-oat device comprising:
a shaft member which is columnar or cylindrical; a cylinder member which is cylindrical and through which the shaft member is inserted so that the cylinder member is movable in a direction of a central axis of the shaft member, the cylinder member being shorter than the shaft member and extending in the direction of the central axis of the shaft member; a moving member which moves a plurality of seal members in a direction of a distal end of the shaft member, the seal members being stacked on the shaft member and the cylinder member; and a taking-out member which takes out the seal members from the distal end of the shaft member.

2 . The seal member taking-out device according to claim 1 , wherein the cylinder member is moved in the direction of the distal end of the shaft member together with the seal members by a friction force generated when inner peripheral surfaces of the stacked seal members abut against an outer peripheral surface of the cylinder member.

3 . The seal member taking-out device according to claim 2 , wherein the shaft member has a proximal end located lower in a gravity direction than the distal end thereof, and the cylinder member falls under its own weight when number of the seal members stacked on the outer peripheral surface of the cylinder member is reduced after upward movement with a result that the friction force is rendered smaller.

4 . The seal member taking-out device according to claim 1 , wherein the shaft member has a diameter-expanded part formed on a distal end part thereof to have an outer diameter larger than an inner diameter of the cylinder member.

5 . The seal member taking-out device according to claim 1 , wherein the shaft member has a cushion member provided on an outer periphery of a proximal end part thereof.

6 . The seal member taking-out device according to claim 3 , wherein the shaft member has a diameter-expanded part formed on a distal end part thereof to have an outer diameter larger than an inner diameter of the cylinder member.

7 . The seal member taking-out device according to claim 6 , wherein the shaft member has a cushion member provided on an outer periphery of a proximal end part thereof.
