モータ６の排気口に接続された消音器である。In an air sweater, for example, an air motor with a rotating movable blade, the movable blade slides while being pressed against the inner peripheral surface of the cylinder due to centrifugal force, so in order to prevent wear of the movable blade, lubrication is added to the compressed air supplied to the air motor. Lubrication is performed by supplying oil and atomizing it. For example, Figure 1 shows a pneumatic circuit that supplies operating compressed air to an air motor that drives a motor valve. In the figure, 1 is a filter connected to a compressed air supply source through a pipe 2, and 3 is a filter. This is a pressure reducing valve that reduces the pressure of compressed air supplied through 1. The pipes on the outlet side of the pressure reducing valve 3 are the first pipes, and switching valves 7 and 8 are provided in the middle of these pipes 4 and 5, respectively.

を設けたことを４′８徴とする。However, the first and second operating air supply lines 4 and 5
The pipes are quite long, and there are many pulps along the way, so when air passes through these pipes, a considerable portion of the atomized oil is absorbed into the pipe walls and the pulp. It is unavoidable that it will stick to the inner surface of the product and be lost. Therefore, there is a risk that the amount of lubricating oil actually supplied to the air motor will be reduced and the air motor will not be sufficiently lubricated, and there is a drawback that it takes a long time to replenish the air motor, especially when starting the air motor. Furthermore, in order to supply a sufficient amount of lubricating oil to the air motor, a very large oil supply device 16' was required. As a result, the equipment became larger and the consumption of lubricating oil was high.The purpose of the present invention is to ensure that a sufficient amount of lubricating oil is always available without using a large oil supply device. The method and apparatus for lubricating an air motor that can supply oil to the air motor at the time of starting the air motor, which is supplied with compressed air for operation through an operation air supply circuit, is provided. At this time, a lubricating air pipe is provided near the air motor that bypasses a portion of the air flowing through the operating air supply circuit from the operating air supply circuit, and the atomized 7'c lubricating oil is supplied to the air motor through the lubricating air pipe. Further, the oil supply device of the present invention implementing the above method is characterized in that a differential pressure generating means is provided in a portion of the operating air supply circuit close to the air motor, The refueling air piping is led out to actively generate an air flow within the refueling air distribution pipe due to the pressure difference before and after the differential pressure generating means, and The provision of an oil supply device for supplying lubricating oil is considered to be the characteristic 4'8.

６に運ばれ、エアモータ６を潤滑する。In Fig. 2, speed control valves 11 and 12 are provided to adjust the rotational speed of the air motor 6 by arbitrarily changing the operating air pressure. There is always a pressure difference before and after the air motor, and this valve is located close to the air motor, so in this embodiment, these speed control valves 1
1 and 12 as differential pressure generating means, when the valve is opened, the operating compressed air passes through the filter 1 and the pressure reducing valve 3 and then flows into the first operating air supply pipe 4. The air flows into the air motor 6 via the switching valve 7, the limit pulp 9, and the speed control valve 11. At this time, since there is a pressure difference before and after the speed control valve 11, a portion of the operating air also flows into the oil supply air pipe 17, and this operating air flows into the air motor 6 through the oil supply device 16A. The oil feeder 16A pumps up the lubricating oil in the oil tank using negative pressure generated by air flow and drips this lubricating oil into the pipe 17 at a constant speed. It is possible to use a material similar to that used in 071"1ehi-CvmTi"10"・0" 21 which is atomized and carried to the shear motor 6 by the air flow in the refueling air piping 17, and then the air motor 6 Lubricate.

is discharged from. At this time, air from the air motor also tries to flow into the refueling air piping 18, but since this piping 18 is provided with a check valve 20, the rc air inside the piping 18 is prevented from flowing backwards. Therefore, the oil supply device 16
You will not receive a B salary. Note that if the oil feeders 16A and '16B are constructed to prevent lubricating oil from dripping when air flows backward, the check valves 1g and 20 can be omitted.

７を通して行なわれる。When the valve 14 opens to a predetermined opening degree due to the rotation of the air motor 6, the limit pulp 9 automatically closes to stop the supply of operating air. During the valve closing operation, operating air is supplied from the second operating air supply pipe 5 side, and the air motor is supplied with oil through the oil supply air pipe 18 by the oil supply device 16B. In this case, exhaust is performed through the muffler 15 and the switching valve 7.

できるようになり、給油器１６Ａ。With the above configuration, the loss of lubricating oil will be reduced, so it is sufficient to use small diameter pipes as the lubricating air pipes 17 and 18. Also, since the amount of lubricating oil consumed will be reduced, the lubricating oil can be used as the lubricating units 16A and 16B. A small one can be used. Furthermore, the air piping for lubrication can be guided to the optimal location where lubrication of the air motor is most needed, regardless of the supply of operating air to the air motor, making it possible to provide optimal lubrication according to the structure of the air motor. Also, by making the oil dispenser more compact, the installation location of the oil dispenser can be freely selected.

る。In the above example, a lubricant with a structure that drips lubricating oil at a constant rate was used as the lubricant, but if such a lubricant is used, the lubricant can be refilled by adjusting the number of oil droplets dripping per unit time. The amount can be adjusted precisely. However, the present invention is not limited to the use of such an oil supply device, and in some cases, it may be possible to use an oil supply device or oil supply device with a simple structure that uses an air flow to blow off the oil sucked up from the tank using the Venturi effect and atomize it. Any other type of lubrication device may also be used, such as a pump-based lubrication device.

It is natural that there is. Furthermore, the type of air motor is also arbitrary.

Furthermore, the air piping for oil supply can be guided to a location convenient for lubrication of the air motor regardless of the supply of operating compressed air to the air motor, so it is possible to supply oil to the most suitable parts of the air motor for proper lubrication. It has the advantage of providing lubrication. In particular, according to the refueling device of the present invention, since the refueling air piping is led out from before the differential pressure generating means, an air flow is reliably generated in the refueling air piping to ensure reliable and stable refueling. I can do it.

, transfer it to J, and change the accompanying "open." to [open < (a-+b)
. ” is corrected. (3) Change “close,” in the second line of page 4 to [close (b-+c)
Correct to J. (4) Change "Open." in the third line of page 4 to "Open < (a-+b).
. ” is corrected. (5) Page 5, lines 10 to 14, “Don’t be lost...
there were. "Also" should be corrected as follows. [The oil that is lost and adhered to the pipe wall or inner surface of the pulp during the next reversal operation will necessarily be exhausted from the exhaust port C of the switching valve 7 or 8 due to the backflow of air, The amount of lubricating oil that reaches the air motor is extremely small, and the air motor is not sufficiently lubricated, which has the drawback that it takes a long time to replenish the air motor, especially when starting the air motor. therefore"
that's all
