Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a valve, a pipe joint, etc.
The present invention relates to an O-ring supply device that can easily perform an automatic assembly process by supplying O-rings one by one to an automatic assembly device or the like of a device that needs to incorporate an O-ring.

[0002]

2. Description of the Related Art As an O-ring feeding device of this type, for example, a feeding device in which a vibrating parts feeder and a pallet are combined is sometimes used, but the O-rings are fed one by one from the parts feeder to the pallet. Is difficult. And a soft O-ring may damage the surface. Therefore, the automatic valve assembly system (Japanese Patent Application No. 3-24566) filed earlier describes the adoption of a screw rotary type component supply device.

FIG. 5 is a perspective view showing an outline of the screw rotary type component supplying apparatus. That is, it is composed of a screw bar 101 having a square screw thread cut off and a catcher 102. Plural O-rings to be supplied are inserted into the screw bar 101 and temporarily held, and the screw bar 101 is rotated to rotate the screw bar 101. O suspended in the valley of the square screw of the bar 101
The rings are sent to the square screws of the screw bar 101 and sequentially moved, and the catcher 1 is fed one by one from the tip of the screw bar 101.
It is configured to be dropped on 02 and transported.

[0004]

However, in the above-mentioned conventional example, when a plurality of O-rings are gathered at one place and are hung on the screw bar 101, there is one groove at each trough of the square screw of the screw bar 101. There is a problem in that the sheets are not suspended one by one and cannot always be supplied smoothly one by one, which hinders the next process.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and an object thereof is to provide an O-ring supply device capable of surely supplying one O-ring to an automatic assembling device or the like. To do.

[0006]

Therefore, an O-ring feeding device according to the present invention has an O-ring carrying rod having a screw-shaped groove for inserting and suspending an O-ring and moving the O-ring in the distal direction. The O moved to the tip of the ring transfer rod
O that holds one ring and removes it from the O-ring carrying rod
The object is to achieve the above-mentioned object by a structure characterized by comprising a ring take-out jig.

[0007]

With the above construction, the plurality of O-rings fitted in the O-ring carrying rod and suspended in the screw-shaped groove move toward the tip end portion on the O-ring carrying rod by the rotation of the O-ring carrying rod. The O-rings located at the tip of the O-ring carrying rod can be taken out one by one by the O-ring take-out jig and passed to the next step.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The O-ring supply device according to the present invention will be described below with reference to embodiments.

A plurality of O-rings 2 to be supplied are inserted and temporarily held. By rotating the O-ring carrying rod 1, the O-ring 2 suspended and retained by the screw 3 can be moved in the distal direction.

The O-ring take-out jig 5 has a function of holding one O-ring 2 located at the tip of the O-ring carrying rod 1 and removing it from the O-ring carrying rod 1.

Specifically, a pair of hands 7 sandwiching the O-ring located at the tip of the O-ring carrying rod 1 from both sides.
As shown in an enlarged view of FIG. 3, a groove 7a with which the O-ring 2 is engaged is formed on the inner surface side of the hand 7. The bottom surface of the groove 7a is knurled to prevent the sandwiched O-ring 2 from falling off, or a non-slip process such as sticking a rubber plate having a rough surface is applied.

Next, the operation will be described.

The O-ring take-out jig 5 is brought close to the O-ring 2 sent to the tip of the O-ring carrying rod 1, and only one O-ring 2 is sandwiched and held by the hand 7, and the O-ring carrying jig 8 is provided. The O-ring 2 that has been moved to and held above is released and transferred to the O-ring carrying jig 8.

With the above configuration and operation, the O-rings 2 can be reliably supplied one by one to the automatic assembling apparatus or the like.

(Third Embodiment) FIG. 4 is a perspective view showing the essential parts of the third embodiment, showing a state in which one O-ring located at the tip of the O-ring carrying rod is about to be taken out. Shows.

In the figure, the O-ring carrying rod 1 has a structure according to the second embodiment, and a plurality of O-rings 2 to be supplied are inserted and temporarily held, and the O-ring carrying rod 1 is rotated. As a result, the O-ring 2 suspended by the screw 3 can be moved in the distal direction.

The O-ring take-out jig 5 has a function of holding one O-ring 2 located at the tip of the O-ring carrying rod 1 and removing it from the O-ring carrying rod 1.

Specifically, a pair of V-shaped hands 7 sandwiching one O-ring located at the tip of the O-ring carrying rod 1 from both sides is provided. The V-shaped hand 7 has a structure in which the angle of the V-shape can be changed so as to hold and release the O-ring 2. A groove 7a with which the O-ring 2 is engaged is formed on the inner surface side of the hand 7 as in the second embodiment.

Next, the operation will be described.

The O-ring take-out jig 5 is brought close to the O-ring 2 fed to the tip portion of the O-ring carrying rod 1, and only one O-ring 2 is sandwiched and held by the hand 7, and a guide 9 having a feeding mechanism is provided. Is guided to move to a predetermined position, the hand 7 is opened, and the held O-ring 2 is transferred to the next process.

With the above configuration and operation, the O-rings 2 can be reliably supplied one by one to the automatic assembling apparatus or the like.

[0031]

As described above, according to the present invention, a plurality of O-rings fitted to the O-ring carrying rod and suspended in the screw-shaped groove on the surface of the O-ring carrying rod are rotated by the O-ring carrying rod. Move on the rod toward the tip. The O-ring located at the tip of the O-ring transfer rod
