Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supply container used for automatically supplying an appropriate amount of lubricating oil to, for example, an operating air cylinder.

[0002]

2. Description of the Related Art Pistons, packings, and the like that reciprocate in an air cylinder are easily worn, so that a small amount of atomized lubricating oil is mixed into compressed air for lubrication.

FIGS. 4 and 5 show a conventional supply container for supplying lubricating oil to the air cylinder. The container body (1) has an outer cylinder (2) made of a bottomed cylindrical aluminum alloy or the like. )When,
It comprises a cylindrical bottom lid (3) with a bottom facing downward and a transparent synthetic resin inner cylinder (5) housed in an outer cylinder (2). On the front surface of the outer cylinder (2), a vertically long transparent hole (4)
Are formed. A lubricating oil (6) is stored in the inner cylinder (5).

[0004] An oiling cylinder (7) is provided upright on the upper surface of the upper lid (3), and the upper end thereof is removably closed by a cover (8). A horizontal air supply pipe (9) for supplying compressed air to an air cylinder (not shown) is provided at an intermediate portion of the upper lid (3).
Are penetrated while maintaining airtightness, and a communication hole (10) communicating with the inside of the inner cylinder (5) is formed in a part thereof.

[0005] An oil-absorbing pipe (11) whose lower end is opened near the bottom surface of the inner cylinder (5) is vertically provided substantially on the center axis of the inner cylinder (5) in the air supply pipe (9), and is formed at the upper end thereof. Nozzle (12)
Are directed in the flow direction of the compressed air in the air supply pipe (9).

In the above-described conventional supply container, when compressed air is supplied in the direction of the arrow to the air supply pipe (9) in order to operate the air cylinder, the inside of the inner cylinder (5) is filled with the air supply pipe (5) by the communication hole (10). 9) The pressure becomes equal to the inside. Thereby, the lubricating oil (6)
Oil passing through the intake pipe (9) at high speed,
Through the nozzle, and flows into the air cylinder in a state of being atomized by the nozzle (12) to lubricate the inside of the air cylinder.

[0007] The amount of the lubricating oil (6) of the inner cylinder (5), which is gradually reduced by lubrication to the air cylinder, is increased by increasing the amount of the lubricating oil through a transparent hole.
It can be known by looking through (4), and when it has decreased to near the lower limit, replenish it appropriately from the refueling cylinder (7).

[0008]

However, in the above-mentioned conventional container, since the lubricating oil (6) is usually colorless and transparent, the lubricating oil (6) depends on the position of the see-through hole (4) and the brightness of the installation place. In some cases, the oil level could not be confirmed accurately or could be mistaken, especially when the inner cylinder (5) became dirty due to long-term use. The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a lubricating oil supply container that allows the remaining amount of lubricating oil to be accurately visually recognized irrespective of installation conditions and the like. I have.

[0009]

According to the present invention, the above-mentioned problem is solved as follows. (1) The transparent inner cylinder in which the lubricating oil is stored and from which the lubricating oil flows out is accommodated in an outer cylinder having a vertically long transparent hole on a side surface, and the inner tube is passed through the transparent hole. In a lubricating oil supply container for visually checking the remaining amount of lubricating oil in a cylinder, a plate-like float colored in a color different from the color of the lubricating oil is provided on an oil surface of the lubricating oil in the inner cylinder. Float.

(2) In the above item (1), the inner cylinder and the outer cylinder are formed of a non-magnetic material, and a permanent magnet is fixed to the lower surface of the float, and the lower limit position of the float is provided on the lower surface of the outer cylinder. Detected by the magnetic sensor.

[0011]

1 and 2 show a first embodiment of the present invention. The supply container main body is the same as the above-mentioned conventional one, and the same members are denoted by the same reference numerals. The detailed description is omitted.

On the oil surface of the lubricating oil (6) stored in the inner cylinder (5), an annular and plate-shaped, for example, made of foamed polyethylene, having an outer diameter slightly smaller than the inner diameter of the inner cylinder (5), A white float (13) is floated, and an insertion hole (14) at the center of the float (13) penetrates the oil absorbing pipe (11).

As described above, when the float (13) is floated on the oil surface, the float (13) can be moved up and down through the see-through hole (4) regardless of the location of the supply container and the brightness of the surroundings. The position can be easily visually recognized, and the amount of residual oil in the inner cylinder (5) can be accurately confirmed.

The color of the float (13) is not limited to white, but may be colored in a conspicuous color different from that of the lubricating oil (6). FIG. 3 shows a second embodiment of the present invention. The same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The outer cylinder (2) and the inner cylinder (5) are made of a non-magnetic material such as aluminum.

A permanent magnet (15) is fitted on the lower surface of the float (13), and an alarm such as a buzzer (not shown) is provided on the lower surface of the outer cylinder (2) facing the permanent magnet (15). A magnetic (proximity) sensor (16) for operating the device is mounted.

In the second embodiment, the lubricating oil (6) in the inner cylinder (5) decreases to near the lower limit, and the float (13) is
When the magnetic sensor (16) descends near the bottom of (5), the magnetic sensor (16) is activated, and an alarm is issued by a buzzer or the like.

The present invention can of course be applied to a container in which the lubricating oil flows out of a part of the container in addition to the lubricating oil supply container for the air cylinder.

[0019]

According to the first aspect of the present invention, the float colored in a different color from the lubricating oil is floated on the oil surface of the lubricating oil. The remaining amount can be easily visually recognized, and occurrence of an accident such as running out of oil can be prevented.

According to the second aspect of the present invention, if the residual oil level becomes close to the lower limit even if the operator does not watch the residual oil level or neglects to check the residual oil level due to the carelessness of the operator, the operation of the magnet and the magnetic sensor is automatically performed. Since an alarm or the like is issued to the user, it is possible to prevent the occurrence of an accident due to lack of oil.
