Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a grease applicator that automatically applies grease.

Prior Art and Problems When applying grease to moving parts of a machine, conventionally, as shown in FIG. It had the following shortcomings: In other words, since the grease is applied manually, it is difficult to apply an even amount of grease, and the grease on the hands and fingers may adhere to areas where it should not be applied while handling the workpiece. I was afraid that I would. Furthermore, since the grease is applied using the brush 1, there is a risk that hairs that come off during the application of the grease may adhere to the application surface and cause a malfunction.

OBJECTS OF THE INVENTION The present invention has improved the above-mentioned drawbacks, and its purpose is to automatically apply a predetermined amount of grease to a predetermined location on a workpiece. Examples will be explained in detail below.

Embodiment of the Invention FIG. 2 is a configuration diagram of an embodiment of the present invention, in which 2 is grease, 3 is a U-shaped storage plate as shown in FIG. 3, and 4 is a groove provided in the storage plate 3. 3a and 3b, the gate plate is inserted into and moved up and down by the cylinder 10, 5 is a rubber sheet, 6 is a slider that is moved left and right by the cylinder 11, and the grease 2 is the storage plate 3, the gate plate 4, and the rubber sheet. 5. It is accommodated in the empty space formed by the slider 6. Further, 7 and 8 are pads made of an elastic body such as rubber, and 9 is a support plate to which the pads 7 and 8 are fixed, and can be moved up and down by a cylinder 12. Further, 13 is a workpiece to which grease is applied. In addition, in the figure, illustration of a control section that controls the operations of the cylinders 10 to 12 is omitted.

To apply the grease 2 using the device shown in the figure, first operate the cylinder 10 so that a predetermined distance opens between the chamfered tip of the gate plate 4 and the top surface of the slider 6 as shown in the figure. do.
Next, the cylinder 11 is operated to move the slider 6 in the direction of arrow A. As a result, the grease 2 is applied to the top surface of the slider 6 in a thickness corresponding to the distance between the tip of the gate plate 4 and the top surface of the slider 6, as shown in the figure. Next, cylinder 12
, so that the tips of pads 7 and 8 align with slider 6.
The support plate 9 is lowered until it comes into contact with the upper surface of the pads 7 and 8, and the grease 2 is applied to the tips of the pads 7 and 8. Next, the cylinder 12 is operated to raise the pads 7 and 8 by more than the thickness of the grease applied to the upper surface of the slider 6, and then the cylinder 10 is operated to raise the gate plate 4 by a predetermined amount. Next, cylinder 1
1 to move the slider 6 to the position shown by the dotted line in the figure. The reason why the slider 6 is moved in the direction of arrow B after raising the gate plate 4 by a predetermined amount is because if the slider 6 is moved in the direction of arrow B without raising the gate plate 4,
This is because, as shown in FIG. 4, the grease 2 builds up at the gate plate 4.

Then, the cylinder 12 is operated, and the support plate 9 is lowered until the tips of the pads 7 and 8 come into contact with the greased surface of the workpiece, as shown by the dotted line in the figure, and the grease adheres to the tips of the pads 7 and 8. Apply the grease to the workpiece 13. Next, by operating the cylinder 12, the support plate 9 is raised to a position where the tips of the pads 7 and 8 do not come into contact with the grease applied to the top surface of the slider 6 when the slider 6 is moved in the direction of arrow A. let

As described above, according to this embodiment, the thickness of the grease applied to the top surface of the slider 6 is determined by the distance between the tip of the gate plate 4 and the top surface of the slider 6. If the amount is constant, the amount of grease applied to the tips of the pads 7 and 8 can be made constant, so the amount of grease applied to each workpiece can be made uniform. In addition, since the pads 7 and 8 are made of an elastic material such as rubber, it is possible to apply grease to multiple locations at the same time even when there are steps on the grease application surface. .

FIGS. 5A to 5C are diagrams showing the shape of pads used in the device of the present invention.

The pad shown in Figure A has an acute angle at its tip, and is effective when applied to apply grease to an oblong hole or the like. The pad shown in Figure B has a cut in the tip 20 so that a large amount of grease can adhere to it, and is effective when applied to apply a large amount of grease to an oblong hole or the like. In addition, the pad shown in Figure C has a sponge 21 at its tip and is capable of adhering a large amount of grease, so it is suitable for applying a large amount of grease to a large area. Then it is valid.

Effects of the Invention As explained above, the present invention includes a first control means for reciprocating the slider (consisting of the cylinder 11 in the embodiment) and an application means for applying grease to the upper surface of the slider (in the embodiment In this example, the storage plate 3, the gate plate 4, and the rubber sheet 5) are used to control the amount of grease applied (in the example, the gate plate 4,
Since it is equipped with a second control means (cylinder 12 in the embodiment) that reciprocates the pad (consisting of a cylinder 10), it can automatically apply grease evenly to a predetermined location on the workpiece. It has the advantage that it can be applied to Further, since a brush is not used as in the conventional method, there is an advantage that hairs do not come off on the greased surface and cause malfunctions.
