[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus capable of easily and surely inserting a sphere into a hole, and more particularly to a sphere insertion apparatus suitable for manufacturing a pipe joint coupled using a ball.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a pipe joint that uses a ball for coupling is known. In manufacturing such a pipe joint, it is necessary to insert a plurality of balls on the outer peripheral surface of the coupling member. In this case, in the conventional insertion method, when forming the inner collar to be the coupling member, the ball is set in the mold and embedded in the inner collar, or a tapered hole is drilled in the inner collar. In this case, a ball is fitted from the outer peripheral side (see, for example, Patent Document 1).
[0003]

Japanese Patent Laid-Open No. 6-272895 (page 3, Fig. 2-3)
[0004]
[Problems to be solved by the invention]
However, since the setting of the balls in the mold and the fitting of the balls from the outer peripheral side were performed manually one by one, the workability was poor. In addition, grease may be applied to make it difficult for the ball to fall off, but this causes a problem of contamination. Furthermore, there is a problem in inspection accuracy because it depends on visual inspection whether or not the ball is inserted without forgetting.
[0005]
Accordingly, the present invention provides a device for inserting a sphere into a hole, which can automatically and reliably insert a sphere such as a ball into a hole in a coupling member or the like of a pipe joint, and can greatly improve workability. Is intended to provide.
[0006]
[Means for Solving the Problems]
The present invention has been made to solve the above problems, and the gist thereof is a fixing jig for fixing an insertion target member (10 ) having a hole (11) to the top of a support column (1). (6) , a hopper that accommodates the sphere, a lifting device that moves the hopper up and down along the support column, and a pipe that applies a negative pressure to the hole of the member to be inserted, inside the raised hopper The present invention relates to a device for inserting a sphere into a hole in which the hole is positioned and a negative pressure is applied to the pipe to suck and fit the sphere stored in the hopper into the hole of the member to be inserted.
[0007]
And preferably, it is related to the spherical body insertion device into the hole in which the pipe is passed through the support pillar and the pressure sensor is connected to the pipe located outside the support pillar.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The apparatus for inserting a sphere into a hole of the present invention includes a support column for a member to be inserted having a hole, a hopper for housing the sphere, a lifting device for moving the hopper up and down along the support column, and a hole for the member to be inserted. It consists of piping that applies negative pressure to the part. Here, the insertion target member having the hole is typically a coupling member of a pipe joint, but is not limited thereto. The sphere is typically a ball that is inserted into a coupling member of a pipe joint, but is not limited thereto.
[0009]
Next, the support column supports the member to be inserted and serves as a guide when the hopper that accommodates the sphere is moved up and down. And a hopper moves up and down along a support pillar with a raising / lowering apparatus. Therefore, if a large number of spheres to be inserted are placed in advance with the hopper lowered, and the lifting device is operated after placing the member to be inserted on the upper part of the support column, the hopper is lifted so that the sphere is inserted. It is lifted up to the hole of the target member.
[0010]
In this way, the sphere is transported to the hole of the member to be inserted, the hole is positioned inside the raised hopper, and then negative pressure is applied to the pipe by a pump or the like. Then, a negative pressure acts on the hole of the member to be inserted through the pipe, and the sphere around the hole is sucked into the hole. As a result, the sphere is automatically inserted.
[0011]
Even when the sphere is hardened in the hopper, the sphere is easily moved by the negative pressure because it is loosened by the vibration when the hopper is raised. Therefore, in the sphere insertion device of the present invention, the sphere is easily and reliably inserted into the hole.
[0012]
However, the end of insertion of the sphere can also be monitored. For example, a pressure sensor is connected to the piping, the pressure after the sphere is inserted is confirmed in advance, and the pressure is set as the set value of the sensor. In this case, it is preferable in that the apparatus can be miniaturized by passing the pipe through the support column and providing a pressure sensor in the pipe located outside the support column.
[0013]
Further, if the piping is passed through the inside of the support column, the insertion target member can be arranged as it is on the top of the support column. In addition, since the hole of the insertion target member may be at the top, there is no restriction on the position of the hole, and a fixing jig for the insertion target member can be attached to the top.
[0014]
【Example】
Hereinafter, specific examples of preferred embodiments of the present invention will be described with reference to the drawings. 1 and 2 are conceptual diagrams showing an example of a sphere insertion device into a hole of the present invention. FIG. 1 shows a state before the sphere is inserted, and FIG. 2 shows a state when the sphere is inserted. As shown in FIG. 1, the insertion target member 10 is installed on the top of the columnar support pillar 1 via a fixing jig 6, and a plurality of holes 11 are provided on the side surface of the insertion target member 10. A pipe 4 is passed through the support column 1 and a pressure sensor 5 is connected to the outside of the support column 1.
[0015]
Next, the operation of the sphere insertion device of the first embodiment shown in FIG. 1 will be described. First, as shown in FIG. 1, a large number of spheres 20 are placed inside the hopper 2 while the hopper 2 is lowered by the lifting device 3. Here, since the support pillar 1 passes through the center of the hopper 2 which is a cylindrical container, the sphere 20 is stored so as to surround the support pillar 1.
[0016]
Then, when the lifting device 3 is operated to raise the hopper 2 along the support column 1, the bottom surface of the hopper 2 is an inclined surface and the sphere 20 in contact with the support column 1 rotates. Together, as shown in FIG. 2, the loose sphere 20 surrounds the outer periphery of the hole 11 of the insertion target member 10.
[0017]
Furthermore, when a negative pressure is applied to the pipe 4 by a pump (not shown) with the hole 11 positioned inside the raised hopper 2 as shown in FIG. 2, the negative pressure acts on the hole 11 through the pipe 4. The surrounding sphere 20 is sucked into the hole 11. Therefore, the sphere 20 accommodated in the hopper 2 is easily inserted into the hole 11 of the insertion target member 10.
[0018]
When the sphere 20 is inserted into all the holes 11 of the insertion target member 10, the pressure in the pipe 4 changes. Then, since the pressure sensor 5 senses the pressure after the sphere 20 is inserted, the end of the sphere 20 can be monitored.
[0019]
In addition, the continuous sphere insertion with respect to an insertion object member is attained by lowering the hopper 2 after completion | finish of insertion of the spherical body 20, preparing a new insertion object member, and repeating the same operation | movement.
[0020]
3 and 4 are conceptual diagrams showing another example of the sphere insertion device of the present invention. FIG. 3 shows a state before the sphere is inserted, and FIG. 4 shows a state when the sphere is inserted. The second embodiment shown in FIGS. 3 and 4 uses an insertion target member 10 having a different shape from the first embodiment shown in FIGS. 1 and 2. That is, the hole 11 is provided on the upper surface of the insertion target member 10.
[0021]
In the case of the second embodiment shown in FIGS. 3 and 4, the sphere 20 accommodated in the hopper 2 surrounds the upper surface of the hole 11 of the insertion target member 10. When a negative pressure is applied to the pipe 4 by a pump (not shown), a negative pressure acts on the hole 11 through the pipe 4 and the upper sphere 20 is sucked into the hole 11.
[0022]
