Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention was developed by inserting a valve into the wheel of an automobile tire assembly line. Regarding the device to enter.

0002

[Conventional technology]

Previously, installing valves on the wheels of wheels was done manually, but now In addition to the large number of man-hours required, productivity is low due to the large labor burden when inserting the valve. It required

0003

[Problem that the idea aims to solve]

On the other hand, as a mechanized version of this type of work, the valve is inserted straight into the valve hole, and then the valve is inserted into the valve hole. There is a charging device that grips the valve stem and pulls it in further, but When holding the valve, the valve cap is easily damaged due to the unstable insertion state of the valve, and Because the temporary insertion and subsequent retraction processes are separated, the number of parts in the device increases. It had drawbacks.

0004 Furthermore, the push rod consists of a long rod, and its base is integrated with the pneumatic cylinder. To enable operation, a step is formed at the tip of the rod, and the tip is attached to the flange of the valve. There is an automatic insertion device with a step that can be engaged with the side end surface, but it does not fit the valve insertion of all wheels. Because the direction of the inlet hole is not consistent, the side of the valve may be damaged during insertion, or the valve may become damaged during insertion. However, it has the disadvantage that it is difficult to perform accurately and automatically.

[0005] This invention solves the above problems, prevents damage to the valve, and improves the valve insertion hole. A bar that can be inserted accurately and automatically in accordance with An object of the present invention is to provide a lube insertion device.

[0006]

[Means to solve the problem] In order to achieve this purpose, the present invention has a tip at the valve insertion hole of the wheel. a guide pipe for inserting the valve into the insertion hole, and an inserter for pressing the valve into the insertion hole. In a pressing device consisting of an advancing/retracting drive means having an insertion rod, the tip of the insertion rod is The end portion has a pressing rod that engages a shoulder in the vent hole of the valve and presses the valve. The pressing body is tiltable and the pressing rod returns to an extension of the center line of the insertion rod. It is characterized by being set up so that it can be returned.

[0007]

[Effect]

Place the tip of the guide pipe of the pressing device close to the valve insertion hole of the wheel, and By pressing the insertion rod with the air cylinder, the pressing body is pressed against the insertion rod. Since the tip is tiltably provided, the valve engaged with the pressing rod of the pressing body is It can be inserted accurately and easily by following the insertion hole.

[0008]

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 and 2.

[0009] 1 indicates a wheel, and the wheel 1 has a valve insertion hole 1a into which a valve 2 is inserted. is perforated.

0010 3 indicates a pressing device, the pressing device 3 is provided with the valve 2 at its tip, and The guide pipe 3a and the pressing rod 3b to be inserted into the wheel 1 are It consists of a forward/backward driving means for driving forward/backward, for example, an air cylinder 3c.

[0011] Reference numeral 4 indicates an insertion rod, and the tip of the insertion rod 4 is formed into a concave spherical surface 4a. and a bottomed hollow hole 4c having a diameter-reducing hole 4b at the bottom is bored in the center. There is.

0012 Reference numeral 5 indicates a pressing body, and the pressing body 5 has a shoulder of the vent hole 2a of the valve 2 at its tip. A pressing rod 5b having a flange 5a for pressing the part and a rear end formed into a hemispherical pressing part 5c. At the same time, a pore 5d is bored in the center of the pressing portion 5c.

[0013] Reference numeral 6 indicates an elastic linear body made of, for example, a piano wire. The root side of the insertion rod 4 is fitted into the reduced diameter portion 4b of the insertion rod 4, and a locking body is attached to the end thereof. 6a is screwed, and the tip part is fitted into the pore 5d of the pressing part 5c. It is screwed in by a screw 6b. Note that 7 is a supply pipe that supplies the valve 2. Ru.

[0014] Next, the operation of the valve insertion device configured as described above will be explained.

[0015] First, insert the tip of the guide pipe 3a of the pressing device 3 into the valve insertion hole 1a of the wheel 1. When the valve 2 is inserted from the supply pipe 7 in close proximity, the cylinder 3c of the pressing device 3 When the press rod 3b is moved in the direction of arrow A, it is pressed together with the insertion rod 4. The body 5 also moves in the direction of arrow A, and the flange 5a of the pressing rod 5b of the pressing body 5 touches the valve. 2, and push the valve 2 into the insertion hole 1a of the wheel 1. Sink into it.

[0016] At this time, if the insertion hole 1a is inclined with respect to the plane of the wheel 1, 2, the pressing body 5 bends slightly against the elasticity of the rod-shaped body 6, and the insertion rod 4 on the spherical surface 4a of the valve 2, and the inner surface of the vent hole 2a of the valve 2 and the pressing body 5. Since there is a gap t between the pressure rod 5b and the outer surface, the valve 2 tilts slightly and the insertion hole 1 The valve 2 is inclined corresponding to the inclined surface of a, and is inserted accurately following the insertion hole 1a. It will be done.

[0017] Therefore, problems such as the valve 2 being damaged or being difficult to insert can be solved. Sho valve When the pressing rod 3b retreats after the insertion and locking of the valve 2, the pressing rod 5b separates from the valve 2 and the rod Due to the elasticity of the shaped body 6, it returns to the extension of the center line of the insertion rod 4, and the next valve 2 is inserted. It becomes possible to enter.

[0018] FIG. 3 shows a second embodiment, in which the tip 4 of the insertion rod 4 is a has a convex spherical shape, and the rear end portion of the pressing body 5 has a concave shape; It has the same effect as described above.

[0019] FIG. 4 shows a third embodiment, in which the tip 4 of the insertion rod 4 is A is flat and the rear end of the pressing body 5 is convex, which simplifies manufacturing. have fruit.

[0020] In addition, in addition to the above-mentioned embodiment, the pressing rod 5b is tiltable in either direction and the valve The locking rod 5b detached from the valve 2 after the insertion and locking of the insertion rod 2 is aligned with the center line of the insertion rod 4. A pressing body 5 is provided at the tip of the insertion rod 4 so as to return to an extension of the insertion rod 4. If so, it is optional to use either configuration.

[0021]

[Effect of the idea]

Thus, according to the present invention, the tip of the insertion rod has a shoulder in the vent hole of the valve. A pressing body having a pressing rod that engages with the valve and presses the valve is tiltable and presses the valve. Since the rod is provided so that it can be returned to an extension of the center line of the insertion rod, the tire valve Even if the insertion hole is unevenly formed, the valve can be inserted following the insertion hole. This allows the valve to be inserted accurately and automatically, preventing damage to the valve and improving work efficiency. It has the effect of making it possible to improve the situation.
