As shown in FIG. 7, the take-out portion 14 has a cylindrical portion 14B larger than the inner diameter of the ring member B, and a second inclined portion 14A whose diameter is reduced from the cylindrical portion 14B toward the lower end. The take-out portion 14 extends in the vertical direction. That is, the take-out portion 14 extends in parallel with the rod-shaped portion 13. The lower end of the second inclined portion 14A is smaller than the inner diameter of the ring member B. That is, the lower end of the take-out portion 14 is smaller than the inner diameter of the ring member B at one end, the diameter is expanded toward the upper end which is the other end, and the other end is larger than the inner diameter of the ring member B. Further, the upper end of the take-out unit 14 is connected to a second drive unit (not shown). The take-out unit 14 can freely move in the vertical direction by driving the second drive unit. That is, the take-out portion 14 is movable in the direction in which it extends. The first actuator 30 moves the receiving portion 11 so that the central axis of the taking-out portion 14 and the central axis of the through hole 11P of the receiving portion 11 are coaxial. At this time, the lower end portion, which is one end portion of the take-out portion 14, can be freely inserted and removed from the through hole 11P of the receiving portion 11.

Next, the operation of this ring member cutting device will be described. First, the groove portion 13E of the locked portion 13C of the rod-shaped portion 13 through which the plurality of ring members B are inserted is locked to the claw portion 15E of the locking portion 15B (see FIG. 1).

Next, the working fluid is allowed to flow into the space S of the receiving portion 11 from a supply valve (not shown), and the receiving member 11B, the first piston 11C, and the second piston 11D of the receiving portion 11 are raised with respect to the cylinder 11A. Move in the direction (see FIG. 4). Then, the upper end surface T of the receiving portion 11 comes into contact with the lower surface of the washer 11T of the pair of pin members 11E, and the upward movement is stopped (see FIG. 2). At this time, the gap between the lower end surface of the first inclined portion 13B of the rod-shaped portion 13 and the mounting surface P of the receiving member 11B when the ring member B is mounted on the mounting surface P is the ring member. It is equal to or more than one sheet of the thickness dimension of B and less than two sheets. In the second piston 11D, when the second piston 11D comes into contact with the upper surface of the third concave portion 11J of the receiving member 11B, the mounting surface P and the upper end surface U which is the end surface of the first convex portion 11Q become flush with each other. .. That is, the upper end surface U of the second piston 11D becomes flush with the mounting surface P when the receiving portion 11 moves upward, which is the most other direction.

Next, the second actuator 12C of the extrusion unit 12 is driven to move the extrusion unit 12 downward (see FIG. 5). Then, the lower surface of the extruded portion main body 12A comes into contact with the upper surface of the ring member B located at the top of the plurality of ring members B inserted through the rod-shaped portion 13. Further, when the extrusion portion 12 is moved downward, the plurality of ring members B inserted through the rod-shaped portion 13 are pushed downward and move downward. That is, the extruded portion 12 pushes the ring member B from the other upper end toward the lower end which is one end. Then, the ring member B located at the bottom of the plurality of ring members B is elastically deformed by passing through the first inclined portion 13B to expand the inner diameter, and is placed on the mounting surface P of the receiving member 11B of the receiving portion 11. It will be placed. At this time, the gap dimension between the lower end surface of the second convex portion 13D and the mounting surface P is less than one of the thickness dimensions of the ring member B. Therefore, the second convex portion 13D can suppress the position of the ring member B from being significantly displaced. At this time, the gap between the lower end surface of the first inclined portion 13B of the rod-shaped portion 13 and the mounting surface P of the receiving member 11B of the receiving portion 11 is one piece of the thickness dimension of the ring member B. That is more than two sheets. Therefore, in this ring member cutting device, when one ring member B passes through the first inclined portion 13B, there is no gap for mounting the second ring member B on the mounting surface P, so that the second ring member The ring member B is held by the first inclined portion 13B, and the downward movement of the extruded portion 12 is stopped. Then, after a predetermined time has elapsed, the driving of the second actuator 12C is stopped. The through hole 11P of the receiving portion 11 communicates with the inside of the ring member B cut out and placed on the mounting surface P.

Next, the second actuator 12C of the extrusion unit 12 is driven to move the extrusion unit 12 upward (see FIG. 6). Then, the extruded portion main body 12A separates from the upper surface of the ring member B. Further, when the working fluid flowing into the space S of the receiving portion 11 is discharged from the space S, the receiving member 11B, the first piston 11C, and the second piston are generated by the elastic force applied to the receiving member 11B from the compression coil spring 11U. The 11D moves until the lower end surface of the receiving portion 11 comes into contact with the upper end surface of the cylinder 11A, and the rod-shaped portion 13 and the receiving portion 11 are in the most distant state. At this time, the rod-shaped portion 13 is located above the outer side of the second recess 11H. That is, the clearance dimension between the lower end surface of the first inclined portion 13B of the rod-shaped portion 13 and the mounting surface P of the receiving member 11B of the receiving portion 11 can be freely changed in the vertical direction which is the axial direction of the rod-shaped portion 13. Is. Further, at this time, the second piston 11D does not move downward with respect to the first piston 11C due to the frictional force of the O-ring 11Z, and the upper end surface U of the second piston 11D is a surface with the mounting surface P. Keep one state.
Next, the receiving portion 11 is moved to a position facing the taking-out portion 14 by the first actuator 30 (see FIG. 7). Specifically, the receiving portion 11 is arranged at a position where the taking-out portion 14 can be inserted into and removed from the through hole 11P by moving the receiving portion 11 in a direction orthogonal to the central axis of the receiving portion 11.

Next, the second drive unit is driven and inserted into the ring member B placed on the receiving unit 11 and the through hole 11P of the receiving unit 11 (see FIG. 8A). At this time, the take-out portion 14 is inserted into the ring member B, and the second piston 11D is pushed down to be inserted into the through hole 11P of the ring member B and the receiving portion 11. Since the outer diameter of the cylindrical portion 14B of the take-out portion 14 is larger than the inner diameter of the ring member B, the ring member B comes into contact with the outer peripheral surface of the cylindrical portion 14B of the take-out portion 14 with a tense force (see FIG. 8B). .). Then, the second drive unit is driven to extract the take-out unit 14 from the through hole 11P of the receiving unit 11 (see FIG. 9). In this way, the ring member B mounted on the mounting surface P of the receiving portion 11 can be taken out from the receiving portion 11 by the taking-out portion 14. That is, the ring member B is taken out by inserting and removing the take-out portion 14 into the through hole 11P.

As described above, when the ring member B inserted through the rod-shaped portion 13 is placed on the receiving portion 11, the ring member cutting device has the lower end surface of the first inclined portion 13B of the rod-shaped portion 13 and the receiving portion 11. The gap between the receiving member 11B and the mounting surface P is one or more of the thickness of the ring member B and less than two. Therefore, in this ring member cutting device, when the ring member B is mounted on the mounting surface P, there is no gap for mounting the second and subsequent ring members B on the mounting surface P. Therefore, in this ring member cutting device, the second and subsequent ring members B are held by the first inclined portion 13B. As a result, the ring member cutting device can cut out the ring member B one by one. Further, the lower end of the first inclined portion 13B of this ring member cutting device is larger than the inner diameter of the ring member B. Therefore, in this ring member cutting device, the first inclined portion 13B can prevent the ring member B from falling off from the rod-shaped portion 13.

Therefore, the ring member cutting device of the present invention can cut out the ring member B satisfactorily.

Further, the mounting surface P is recessed in the central axial direction and is formed in the second recess 11H whose inner diameter is larger than the outer diameter of the ring member B, and the receiving portion 11 is movable in the axial direction of the rod-shaped portion 13. .. Therefore, in this ring member cutting device, by mounting the cut out ring member B on the mounting surface P, the position of the cut out ring member B can be fixed in the second recess 11H, and the position of the ring member B can be fixed. Can be suppressed from being significantly deviated.
Further, in this ring member cutting device, when the rod-shaped portion 13 and the receiving portion 11 are farthest apart, the rod-shaped portion 13 is located above the second recess 11H. Therefore, this ring member cutting device can increase the dimension between the lower end of the first inclined portion 13B of the rod-shaped portion 13 and the mounting surface P, and can easily receive the cut out ring member B from the receiving portion 11. Can be taken out.
Further, since the receiving portion 11 is movable in the vertical axis direction, the drive mechanism can be arranged at a lower position in this ring member cutting device as compared with the case where the rod-shaped portion 13 is moved, and the device structure such as the lead wire can be arranged. It can be easy.

Further, the receiving portion 11 is movable in the horizontal direction. Therefore, the ring member B mounted on the mounting surface P of the receiving portion 11 can be moved in the horizontal direction from directly below the rod-shaped portion 13. As a result, the ring member cutting device can more easily take out the cut out ring member B from the receiving portion 11.

Further, the receiving portion 11 is provided with a through hole 11P communicating with the inside of the placed ring member B. Therefore, this ring member cutting device takes out and grips the ring member B in a centered state by inserting the second inclined portion 14A and the cylindrical portion 14B of the taking-out portion 14 into the ring member B after being cut out. can do.
