Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor oil supply device used to supply lubricating oil to a conveyor chain.

BACKGROUND ART Conventionally, an automatic refueling apparatus A as shown in FIG. 1 has been frequently used as a refueling apparatus for a conveyor for transporting automobile bodies. That is, the passage of the chain roller 1 is detected by the lever 2, and the mechanical air valve 3 is opened intermittently, and the compressed air supplied thereby is intermittently connected to a multiple valve for centrally distributing lubricating oil. The pump 4 is driven to supply lubricating oil to the nozzle means 5 disposed at each lubrication point, and compressed air is supplied to the nozzle means 5, and a small amount of oil is injected into the air from the nozzle 6 of the nozzle means 5. The oil supply device is atomized and supplied to the lubrication point, but since it requires various devices such as a mechanical air pulp 3 for a compressed air system and an lump 4 for a hydraulic system, it is quite large and , the structure is also the
Therefore, they were placed at appropriate locations while taking the layout of the conveyor into consideration, and the lubricating oil was distributed centrally to each lubricating point.

However, the usage conditions of the conveyor are not uniform; for example, in the case of a conveyor with a slope, a conveyor that passes through a drying oven, or a book used to connect two lines, the actual load on the conveyor may vary. There are cases in which wear, etc. cannot be accurately detected until after the feeder is installed, and in such cases, the standard arrangement of the automatic lubrication device alone has the disadvantage that it is not possible to supply the appropriate amount of lubrication. As a countermeasure, while observing the actual wear status of each part of the conveyor, it is necessary to regularly or irregularly use a manual oiling gun to lubricate conveyor chain bins, etc., which have a particularly large amount of wear. There was no choice but to have a good score.

The present invention has been made in view of the cost, and its purpose is to solve the above-mentioned problems and supply an appropriate amount of oil to various types of feeder devices, and
l1lJil! ! Our objective is to provide an easy-to-install lubrication device for a dung conveyor, and its feature is that a lubricating oil container is placed above the conveyor chain, and this container is placed at the top of the locus of movement of the dung conveyor chain bin. The present invention is directed to a feeder oil supply device which forms a flow path leading to the flow path and provides a restriction in this flow path.

When the tip touches the head KW of the conveyor chain bin 9, the oil transfers to this head, and this oil warms the contact surface of the conveyor chain bin 9 (first embodiment).

In this embodiment, the drip lubrication method according to the first embodiment is combined with the so-called ground core lubrication method]
This has the advantage that only the contact surfaces can be properly lubricated intensively. In place of the hypocenter in this embodiment, for example, a bundle of pores in a tube, a metal fiber with medium pores, a felt material with side holes, etc. can be used, but in this case, It is preferable to reset the inner diameter of the drip hole 16m, or to complete the mass production of the manual on-off valve 18, and to replace the manual on-off valve 18 with a Tsuremade type on-off valve.
It is clear that the solenoid could also be energized in synchronization with the red light of the funnel.

As explained above, in the present invention, a lubricating oil container is placed above the conveyor chain to form a flow path from this container to an upper position in the movement locus of the conveyor chain bin. Since the conveyor oil supply device is configured by providing a throttle in the conveyor chain bin, the diameter of the throttle can be set according to the amount of wear on the actual conveyor chain bin and the viscosity of the lubricating oil or lubricant. It is possible to easily supply the appropriate amount of lubricating oil using gravity, and in particular, the #I structure is extremely compact, so it can be used on a conveyor line that is already running on a slope, for example, a conveyor with a slope section, In cases where the load on the conveyor is not uniform, such as a conveyor conveyor passing through a drying oven or a storage conveyor between two lines, and proper lubrication cannot be achieved with just the conventional arrangement of automatic lubrication equipment. The present invention has the advantage that a worker can observe the actual wear and tear condition of the conveyor chain bin and, based on this observation, can easily install the conveyor lubrication device according to the present invention in the appropriate place at the right time. do.
