Abstract

PROBLEM TO BE SOLVED: To accurately feed lubricating oil only to a roller rotating part by aiming the roller rotating part of a chain conveyer with rollers by a nozzle of a spray can and spouting the oil by being linked with the movement of the roller. SOLUTION: A chain conveyer 1 with rollers is driven in the direction shown by an arrow. When a roller 1B is entered in an X point, it is in contact with a small roller 6 and moves in the arrow direction while pushing up the small roller 6. Then, an arm 4 connected to the small roller 6 is tilted about a shaft 5 and a pin 7 provided in the top end part of the arm 4 pressurizes a nozzle head 2A of a spray can 2 so that the oil is spouted from a nozzle 2B. The nozzle 2B is so arranged as to aim the rotating part of a roller 1B one before the roller 1B being in contact with the small roller 6 in spouting the oil. When the roller 1B passes the X point, the small roller 6 is lowered, the arm 4 is returned to its original position, the pin 7 is separated from the nozzle head 2A so as to complete the pushing pressure, and the oil spouting from the nozzle 2B is also stopped.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic lubricating apparatus for lubricating a rotating portion of a roller in a chain conveyor with rollers.

[0002]

2. Description of the Related Art In a chain conveyor with rollers applied to various types of conveyors, it is necessary to frequently lubricate the rotating portions of the rollers to maintain good rotation. This refueling operation requires too much labor by manual operation by a person, and therefore, an automatic refueling device is often used to save labor. 2. Description of the Related Art A conventional automatic refueling device is a device including an oil tank and a dropping port, and is a so-called dropping type in which oil drops are dropped one by one toward a refueling point. When the apparatus is used for a chain conveyor with rollers, an automatic lubricating apparatus is arranged on the chain conveyor with rollers, and the oil is dropped one by one toward the roller rotating portion of the chain conveyor with rollers in operation to supply the oil. I was

However, when oil is supplied by a method in which oil is dropped onto the moving roller rotating section as described above, the speed at which oil is dropped from the automatic oil supply device does not match the speed at which the roller moves.
In many cases, the oil is dropped on a portion other than a portion requiring oil supply, that is, a portion other than a rotating portion of the roller, and there is a problem in terms of reliability. In addition, there is also a problem that the amount of oil used increases.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is possible to supply oil to a roller rotating portion of a chain conveyor with rollers accurately, and it is possible to improve the oil supply. An object of the present invention is to provide a new automatic lubricating device that uses a small amount of oil.

[0005]

SUMMARY OF THE INVENTION An automatic lubricating apparatus according to the present invention is an automatic lubricating apparatus for a chain conveyor with a roller, which includes a jig for fixing a spray can on a chain conveyor with a roller and a shaft. A tiltable arm pivotally supported by the arm, a small roller rotatably held at the end of the arm and arranged to contact the rollers of the chain conveyor with rollers, and provided at the other end of the arm. And a pin arranged at a position to press the nozzle head of the spray can when the arm is tilted, and a spray port which is communicated with the nozzle head and directs its ejection port toward the rotating portion of the roller just before the roller that comes into contact with the small roller. And an arranged nozzle.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a chain conveyor with rollers and an automatic lubrication device according to the present invention. Reference numeral 1 denotes a chain conveyor with rollers. Each of the chains 1A and 1A includes a roller 1B, and the rollers 1B and 1B are arranged at equal intervals. A spray can 2 is arranged on the chain conveyor 1 with rollers by a spray can fixing jig 3. An arm 4 is pivotally supported by a shaft 5 on the frame of the spray can fixing jig 3. A small roller 6 is rotatably held at the lower end of the arm 4, and is disposed at a position where it contacts the roller 1B. Further, a pin 7 is provided at the upper end of the arm 4 and is arranged at a position where the nozzle 4 presses the nozzle head 2A of the spray can 2 when the arm 4 is tilted. In addition, the nozzle head 2A of the spray can 2 is provided with a nozzle 2B, and its ejection port is arranged near the rotating portion of the roller 1B just before the roller 1B with which the small roller 6 contacts.

A method of supplying oil to a roller rotating section of a chain conveyor with rollers that is actually in operation by using the apparatus configured as described above will be described below. Chain conveyor with roller 1
Is driven in the direction of the arrow. When the roller 1B enters the point X, it comes into contact with the small roller 6, and moves in the direction of the arrow while pushing up the small roller 6. Then, the arm 4 connected to the small roller 6 tilts about the shaft 5, and the pin 7 provided at the upper end of the arm 4 presses the nozzle head 2A of the spray can 2, so that oil is ejected from the nozzle 2B. Since the nozzle 2B is arranged so as to aim at the rotating portion of the roller 1B just before the roller 1B which has come into contact with the small roller 6 at the time of oil ejection, oil is not injected to a portion other than the rotating portion. When the roller 1B passes through the point X, the small roller 6 moves down, the arm 4 returns to the original position, and the pin 7 moves to the nozzle head 2A.
Since the pressing is finished away from the nozzle, the ejection of the oil from the nozzle 2B also stops. Thereafter, the above operation is repeated while linking the rollers 1B one after another to move and pass the point X, so that the rotating portion of the roller 1B is intermittently refueled.

[0008]

As is apparent from the above description, the automatic lubricating apparatus of the present invention aims at the roller rotating section of the chain conveyor with rollers by the nozzle of the spray can and injects the oil by linking to the movement of the rollers. Oil can be accurately supplied only to the roller rotating section. In addition, since oil can be intermittently supplied only to the target at a minimum time, the amount of oil used can be smaller than before.
