Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a butterfly valve assembly device, and particularly to a slotted type butterfly valve assembly device.

[Prior art and its problems]

Generally, when assembling a suriwa-type butterfly valve, it is done manually.
As shown in FIGS. 5 and 6, a shaft 32 is rotatably disposed within the cylinder 31 of the butterfly valve 30, and the shaft 32 is provided with a slot 33.

After manually inserting the butterfly 34 into the slot 33 of the shaft 32, the screw 3
5, and then press the butterfly 34 with your finger 36 to rotate it together with the shaft 32 to close the butterfly 34, and then move the upper end of the butterfly 34 along the wall of the cylinder 31. The butterfly 34 is fixed to the shaft 32 by pressing and screwing the screw 35 together.

When rotating the shaft 32 during this work, it is essential to temporarily fasten the screw 35 as described above so that the center of the butterfly 34 and the center of the shaft 32 coincide. The problem was that the inside of the machine was narrow, making the work very cumbersome.

This idea solves the problems of the conventional ones as mentioned above, and after conveying the butterfly which is located separately from the cylinder, it is placed in the slot of the shaft with the center of the butterfly aligned with the center of the shaft. It is an object of the present invention to provide an assembly device for a butterfly valve that can be inserted and that can improve the efficiency of assembly work by eliminating the need for temporary fixing, which was conventionally essential.

[Means for solving problems]

In order to solve the above problems, this invention has a butterfly valve support member and an upright member arranged at a predetermined interval on the upper surface of the base, and a butterfly valve supporting member and an upright member are arranged at a predetermined interval on the upper surface of the base. A fixing member is provided that is movable and can be moved toward and away from the butterfly valve support member by a first actuating member, and a connecting member is provided on the fixing member so as to be movable in the vertical direction by a second actuating member. A butterfly chuck jig having a curved portion on the lower surface of the tip that matches the outer peripheral surface of the shaft of the butterfly valve at the end of the connecting member on the butterfly valve supporting member side and a vacuum pad on the lower surface is swung in the vertical direction. A butterfly setting jig for placing the butterfly on the upper surface is disposed on the upper surface of the base below the butterfly chuck jig. The butterfly placed on the butterfly setting jig is raised when the second actuating member is actuated, and then, when the first actuating member is actuated, it is inserted into the slot of the shaft so that the center of the shaft and the center of the butterfly are aligned. When they match, the shaft and butterfly are rotated together by the second actuating member to hold the butterfly in a pressed state against the wall of the cylinder.

[Effect]

By adopting the above-mentioned means, this idea
The butterfly placed on the top surface of the butterfly setting jig is attracted and raised by the vacuum pad of the butterfly chuck jig when the second actuating member is actuated, and is then supported by the butterfly valve support member when the first actuating member is actuated. The butterfly valve is inserted into the slot in the shaft of the butterfly valve to align the center of the shaft with the center of the butterfly, and the second actuating member allows the butterfly valve to be positioned inside the slot in the shaft and aligned with the center of the shaft. Since the butterfly is pressed and held against the wall surface of the cylinder by rotating the butterflies with their centers aligned, temporary fixing of screws is not necessary.

〔Example〕

Embodiments of this invention shown in the drawings will be described below.

FIG. 1 shows a butterfly valve assembly device according to this invention, in which an upright member 2 is provided on the upper surface of a base 1, and a first actuating member 3 is disposed on the upper part of the upright member 2 so as to be horizontally retractable. In addition, two guide shafts 4 and 5 are disposed in the center of the upright member 2 at a predetermined interval in the vertical direction so as to be movable in the horizontal direction.

Then, a fixing member 7 whose upper portion projects horizontally is attached to the operating rod 6 of the first operating member 3 and both guide shafts 4 and 5, and this fixing member 7 is attached to the first operating member 3. The horizontal part 7a of the fixing member 7 has a second
The actuating member 8 is installed upright so that its actuating rod 9 can be retracted and retracted in the vertical direction, and the connecting member 10 is attached to the actuating rod 9 in a horizontal direction.
0 can be moved up and down.

A butterfly chuck jig 12 is attached to the tip of the connecting member 10 so as to be able to swing vertically via a shaft 11.
It is pivoted.

This butterfly chuck jig 12 has a vacuum pad 13 connected to a suction source (not shown) on its lower surface, and a curved portion 12a on the lower surface of the tip that matches the outer circumference of the shaft 16 of the butterfly valve 15. It is becoming.

Further, a step portion 10 is provided on the lower surface of the connecting member 10.
a is formed so that the fixing member 7 side faces downward, and when the butterfly chuck jig 12 is in its normal horizontal state, its lower surface coincides with the lower surface of the tip of the connecting member 10. ing.

Then, a stepped portion 10a on the lower surface of the connecting member 10
When the curved portion 12a of the butterfly chuck jig 12 comes into contact with the outer peripheral surface of the shaft 16,
The radius is slightly larger than the radius of the butterfly 17.

Further, on the upper surface of the base 1, below the butterfly chuck jig 12,
A butterfly setting jig 18 for mounting the butterfly 17 is provided on the upper surface, and a butterfly valve support member 19 is provided on the opposite side of the butterfly setting jig 18 from the upright member 2.

This butterfly valve support member 19 has an inclined end surface, and this inclined end surface coincides with the opening end surface of the butterfly valve 15.

Next, the operation of the above will be explained.

First, in the state shown in FIG. 1, the first actuating member 3 and the second actuating member 8 are in an inoperative state, so the butterfly chuck jig 12 is in its initial state. The butterfly 17 is placed on the upper surface of the butterfly setting jig 18 on the upper part of the butterfly valve support member 1.
The butterfly valve 15 is located at 9.

From this state, when the second actuating member 8 is first actuated to project its actuating rod 9, the connecting member 10 connected thereto and the butterfly chuck jig 12 pivotally attached to the tip of the connecting member 10 are integrated. The lower surface of the butterfly chuck jig 12 comes into contact with the butterfly 17 placed on the upper surface of the butterfly setting jig 18.

The vacuum pad 13 provided on the lower surface of the butterfly chuck jig 12 attracts the butterfly 17 because it has been suctioned by a suction source in advance. 10a is located outward from the outer peripheral surface of the butterfly 17, so the adsorption of the butterfly 17 by the vacuum pad 13 is not hindered.

When the vacuum pad 13 attracts the butterfly 17 in this way, the second actuating member 8 operates in the opposite direction to move the connecting member 10 and the butterfly chuck jig 12 upward, and the butterfly 17 is moved upward. They rise together to reach the initial state.

Next, when the first actuating member 3 is actuated, the connecting member 10 and the butterfly chuck jig 12 move to the left in FIG. The butterfly 17 moves to the left from the state shown in FIG. When the tip end surface is in contact with the edge of the second actuating member 8
operates slightly and the butterfly chuck jig 12
And butterfly 17 descends, butterfly 17
The lower surface of the tip is in contact with the inner surface of the slot 20 of the shaft 16.

Thereafter, the first actuating member 3 operates again to move the butterfly 17 in the horizontal direction and move the shaft 16.
Insert it into the inside of the slot 20.

In this way, the butterfly 17 is inserted into the slot 20 of the shaft 16, and then,
Curved portion 1 at the tip of butterfly chuck jig 12
When 2a comes into contact with the outer circumferential surface of the shaft 16, the operation of the first actuating member 3 is stopped and the state shown in FIG. 3 is achieved.

In such a state, the first actuating member 3 maintains its state and the second actuating member 8 starts operating again, thereby causing the connecting member 10 to start operating again.
will be lowered.

Then, the butterfly chuck jig 12 has a curved portion 1 at its tip with respect to the connecting member 10.
2a is in contact with the outer circumferential surface of the shaft 16, and is pivotally connected to the connecting member 10 via the shaft 11, so that it swings clockwise about the shaft 11, Further, since the lower end of the connecting member 10 comes into contact with the upper surface of the butterfly 17, the butterfly 17 is rotated together with the shaft 16 while being located inside the slot 20 of the shaft 16, so that the outer circumferential part touches the wall of the cylinder 14. They are held in the abutting state, resulting in the state shown in FIG.

Therefore, in this state, if screws are screwed into the screw holes provided in the butterfly and shaft using the screw robot 21 provided separately, and the screws are fastened, the shaft 16 and the butterfly 17 are fixed by the screws. Moreover, the center of the shaft 16 and the center of the butterfly 17 are fixed in alignment.

After this, if the first actuating member 3 returns to its initial state and the second actuating member 8 also returns to its initial state, the initial state shown in FIG. 1 will be reached. By repeating the steps above, you can attach a butterfly to the shaft.

In the above embodiment, a case was explained in which one butterfly was placed on the upper part of the butterfly setting jig 18, but if a plurality of butterflies were placed on the upper part of the butterfly valve support member 19.
The butterfly valves 15 can be sequentially inserted into the slots of the shaft by simply positioning the butterfly valves 15 in sequence, and then they can be attached together using a screw robot. The operation timing of the two operating members and the movement stroke of the operating rod are controlled by conventionally known control means, and the same applies to the operation of the screw robot. Although we have described the case in which the screws are installed, the work efficiency can be significantly improved even if they are installed integrally on the top surface of the base, or if the screws are screwed in manually without using a screw robot.

[Effect of idea]

By configuring this device as described above,
The butterfly placed on the top surface of the butterfly set jig is adsorbed by the vacuum pad of the butterfly chuck jig that is moved up and down by the second actuating member, and rises, and then the shaft of the butterfly valve is moved by the first actuating member. The center of the shaft and the center of the butterfly can be aligned by inserting the butterfly chuck jig into the inside of the slot and the curved part of the butterfly chuck jig comes into contact with the outer peripheral surface of the shaft. By aligning the center of the shaft with the butterfly, we rotated them so that the butterfly held the cylinder closed, so all that was left to do was to tighten the screws to securely and precisely connect the shaft and butterfly. It has excellent effects such as being able to be installed on the machine, resulting in extremely high work efficiency, and the ability to automatically assemble butterfly valves.
