Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas generation type automatic lubricator for continuously supplying oil to a bearing or the like by utilizing the pressure of gas generated by charging pellets into an electrolytic solution.

[0002]

2. Description of the Related Art Gas-generating automatic lubricators were developed in Germany and are sold worldwide under the trade name of perma. In Japan, Patent Nos. 502733, 1
Patent rights have been acquired by No. 020797 and No. 1667552. The structure is shown in FIG.

A conventional gas-generating type automatic lubricator has a structure in which a lubricating oil A such as grease, a piston 3, and an electrolytic solution B are stacked in this order from the bottom to the top in an airtight container 2 having an oil supply nozzle 1 at the bottom. It has become. The electrolytic solution B is held in the uppermost part of the airtight container 2 by a liquid holding bag 4 made of a gas permeable rubber material.

On the other hand, the pellet C is held in the starting screw 5, and the lid 7 can be removed by screwing the starting screw 5 into the screwing portion 6 provided on the upper surface of the airtight container 2 when the use is started. Then, the pellet C is put into the electrolytic solution B. As a result, gas is started to be generated from the electrolytic solution B, and the gas pressure causes the piston 3 to gradually descend, whereby the airtight container 2
The lubricating oil A therein is continuously discharged from the oil supply nozzle 1 to the outside of the container.

[0005]

This type of automatic lubricator is extremely excellent in principle, and at present, it is far superior to other types of automatic lubricators such as spring type or screw type in terms of performance. There is no such thing.

[0006] The first problem is that the gas generation is started by the start screw, so that it is not reliable. That is, if the user improperly operates the starting screw, the pellet may not be dropped into the electrolytic solution and gas may not be generated. Since the operation of the start screw is artificial, it is difficult to ensure a reliable operation even if the instruction manual is carefully noted. Dropping the pellets into the electrolyte is the basis of the refueling operation, and if this operation has any problems, proper performance cannot be obtained.

In order to most surely execute the dropping of pellets, it is desirable that the user directly puts the pellets into the electrolytic solution by himself / herself. Was impossible.

The second problem is deterioration of the electrolytic solution. In the conventional oil supply device, the electrolytic solution is sealed in the airtight container from the beginning, and if the oil supply device is stored for a long period of time, the effectiveness of the electrolytic solution decreases. The deterioration of the electrolytic solution changes the reaction rate, which seriously affects the supply of the lubricating oil. Therefore, it is impossible to stock for a long period of time, and after a certain period of time, it has to be disposed of, which is very economical.

In order to solve this problem, it is desirable to inject the electrolytic solution at the start of use, but this is also impossible because the conventional oil supply device is of a hermetically sealed type.

An object of the present invention is to provide a gas generation type automatic oiling machine which solves all of these problems by adopting a disassembling and assembling type structure.

[0011]

SUMMARY OF THE INVENTION A gas generation type automatic oil dispenser according to the present invention comprises an oil container having a fuel nozzle at the bottom, a screw-in type main cap for closing the opening of the oil container, and an opening of the oil container. Detachable piston that is inserted into the container from the section, and an oil container that is set from above the main cap into the oil container and that reacts with the pellets to generate gas And a liquid holding bag.

That is, the gas generation type automatic fueling apparatus of the present invention is of the disassembling and assembling type in which the piston and the liquid holding bag can be removed from the oil container.

[0013]

When the use is started, first, with the piston and the liquid holding bag removed, lubricating oil such as grease is injected into the container through the opening of the oil container. Next, the piston is inserted, and after the liquid holding bag is set on the piston, the electrolytic solution is put into the bag. Then, the user himself puts the pellets into the electrolytic solution, and then closes the container opening with the main cap. Thus, all the necessary members and materials are enclosed in the oil container, and gas generation and automatic lubrication by the gas are started.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention. FIG. 2 shows an example of supplying the electrolytic solution.

As shown in FIG. 1, the automatic oil dispenser of this embodiment has an oil container 10 having an upper surface completely opened, a screw-in type main cap 20 for closing the opening of the oil container 10, and an inside of the oil container 10. And a liquid holding bag 40 set on the upper portion of the oil container 10.

The oil container 10 has a lower part formed in a funnel shape and has an oil supply nozzle 11 at the center of the lower surface. Oil container 10
A flange 12 is provided on the outer surface of the middle section. On the outer surface of the container above the flange 12, a male screw portion for screwing the main cap 20 is provided. Oil container 10
Has a tapered surface that is inclined upward toward the inner peripheral side.

The main cap 20 is a bag cap that is externally fitted and mounted on the upper portion of the oil container 10. Main cap 2
On the back surface of the top plate of No. 0, blades 21 and 21 for cutting an oil bag described later are provided in a protruding manner. Further, on the back surface of the top plate portion and the lower end surface of the cylindrical portion, an annular packing 2 for sealing
2, 23 are attached.

The material of the oil container 10 and the main cap 20 is a transparent resin so that the inside can be seen.

The piston 30 is inserted into the container through the opening of the oil container 10 and can move up and down inside the container while hermetically sealing the interior surface of the container.

The liquid holding bag 40 is a so-called flanged container in which a central portion is depressed downward to form a housing portion 41, and an upper end portion thereof projects toward the outer peripheral side to form a flange portion 42.

The container 41 of the liquid holding bag 40 is provided in the oil container 10
Is inserted into the container through the opening. The flange portion 42 is
The main cap 20 is engaged with the upper end surface of the oil container 10 and is screwed onto the upper part of the oil container 10, so that the main cap 20 is gripped between the main cap 20 and the oil container 10.

The material of the liquid holding bag 40 is, for example, a rubber material having gas permeability.

In order to use the automatic lubricator of this embodiment, in the disassembled state of the lubricator, first, lubricating oil A such as crease is injected into the container through the opening of the oil container 10. Next, the piston 30 is loaded into the oil container 10 and the liquid holding bag 40 is set on the oil container 10 from above.

After the liquid holding bag 40 has been set, a predetermined amount of the electrolytic solution is stored in the accommodating portion 41 of the liquid holding bag 40 by a single-use type manual feed 50 in which the electrolytic solution is enclosed, as shown in FIG. Inject B. Then, the user puts the pellet C into the electrolytic solution B by himself, and finally, the oil container 10
The main cap 20 is screwed into the upper part of the to seal the opening.

In this way, the lubricating oil A, the piston 30, the liquid holding bag 40, the electrolytic solution B and the pellet C are enclosed in the oil container 10, and the electrolytic solution B reacts with the pellet C to start generating gas. As a result, the gas passes through the liquid holding bag 40 and pushes down the piston 30, and the lubricating oil A in the oil container 10
Is gradually discharged from the refueling nozzle 11 to the outside of the container.

When the lubricating oil A in the oil container 10 is consumed,
Disassemble the lubricator again and reassemble using the same procedure as above. As a result, the fuel filler is repeatedly used.

In any use, since the user himself / herself puts the pellet C into the electrolytic solution B, there is no mistake in making the pellet, and a reliable lubrication operation is always performed.

In order to increase the oil supply amount, a plurality of pellets C may be charged at the same time, but in that case as well, pellets can be charged easily and reliably.

Further, since the fresh electrolytic solution B is used each time it is used, there is no malfunction due to the deterioration of the electrolytic solution B, and it is not necessary to dispose of the lubricator due to the deterioration.

Furthermore, when the main cap 20 is screwed in, the flange portion 42 of the liquid holding bag 40 is pinched and compressed between the rear surface of the main cap 20 and the upper end surface of the oil container 10 to seal between them. Moreover, since the upper end surface of the oil container 10 is a tapered surface, the tip end bites into the back surface of the franchise portion 42, and particularly excellent sealing performance is ensured. Therefore, gas leakage and liquid leakage during use can be prevented even without the annular packing. As shown in FIG. 5, the upper end surface of the oil container 10 may be a tapered surface with a chamfered tip.

FIG. 3 shows another electrolytic solution supply method. Here, instead of the manual feed 50, a liquid bag 6 containing an electrolytic solution B.
Use 0. The bag body of the liquid bag 60 is made of a thin film that can be easily cut, and has a size that can be loaded into the housing portion 41 of the liquid holding bag 40. A recess 61 for holding the pellet C is formed in the center of the upper surface of the liquid bag 60.

In order to inject the electrolytic solution B into the containing portion 41 of the liquid holding bag 40, the liquid holding bag 40 is set on the upper part of the oil container 10 and then the liquid bag 60 is loaded into the containing portion 41. Then, the pellet C is placed in the recess 61 of the liquid bag 60, and in this state, the main cap 20 is screwed onto the upper portion of the oil container 10.

Due to this screwing, the liquid bag 60 is recessed 6
On the outer peripheral side of 1, the blade portion 21 of the main cap 20 cuts it into a circular shape and opens it. Further, the pellet C is put into the electrolytic solution B in the liquid bag 60 through the cutting opening. This state can be visually inspected by the user through the transparent main cap 20.

That is, also in this supply method, the user himself / herself inserts the pellet C while grasping the situation.

The lubricating oil A can also be packed in the oil and stored in the oil container 10 as in this supply method. The container in that case is preferably a bellows-type container that can be expanded and contracted.

FIG. 4 shows a second embodiment of the present invention. The present embodiment is largely different from the first embodiment in that the gas generating portion is independent of the oil container 10 as the second container 70.

At the center of the bottom of the second container 70, there is provided an opening 71 for letting out the generated gas. Oil container 10
The screw-in type sub-cap 80 mounted on is provided with an opening 81 through which the gas flows. An annular packing 82 for sealing is attached to the lower surface of the cylindrical portion of the sub cap 80. Then, the openings 71, 8
1 are connected by a flexible tube 90. Since other configurations are the same as those of the first embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

Since the automatic oil dispenser of this embodiment is a separate type in which the gas generating portion is separated and independent from the oil container 10,
In addition to the effects of the first embodiment, there is an effect that the reaction can be stably continued at an appropriate temperature even when the oil supply point is abnormally high or low. Further, when the refueling location is located in water or powder, gas can be stably generated outside the location. Further, even when the refueling spot is small, this separate type automatic refueling machine is advantageous.

In the above embodiment, the liquid holding bag 40 is made of a gas permeable material, but it may be a gas impermeable expansion type. Further, in the second embodiment, in order to improve the responsiveness, the space from the liquid holding bag 40 in the second container 70 to the piston 20 in the oil container 10 may be filled with a liquid or a fluid substance. it can.

[0041]

As described above, the gas generating automatic lubricator of the present invention is a separate assembly type lubricator so that the user himself can insert the pellets into the electrolytic solution. It is possible to surely eliminate the malfunction due to. Since the electrolyte can be supplied immediately before use,
It is possible to eliminate malfunctions due to deterioration of the electrolytic solution and eliminate the need to dispose of the lubricator due to the deterioration.
Economic efficiency can be improved. In addition, the refueling device can be repeatedly used, which also improves the economical efficiency.
