Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a grease applicator for applying grease to multiple sliding parts of wiring boards of audio products, mechanical equipment, etc. The present invention proposes a grease applicator with a simple structure that can efficiently apply grease to a large number of locations and that prevents grease from spilling out of the grease hopper.

(Prior Art) Conventional devices for applying grease to multiple locations at the same time are widely used with a structure in which a large number of nozzles are provided corresponding to the locations to be coated and grease is pumped from a grease tank.

Such conventional devices have the disadvantage of requiring expensive and uncomplicated piping equipment, such as numerous pipes and pressure pumps to pump the grease.

When changing the area to be coated, preparation work for the change is troublesome.

(Problems that the invention aims to solve) This invention eliminates the need for expensive equipment such as pressure pumps and numerous pipes, and makes it easy to change the application position. This paper proposes a device.

(Means for Solving the Problems) This invention proposes a grease application device that has simple equipment, can easily change the application position, and does not cause waste such that grease does not adhere to the surroundings of the grease hopper. Its structure includes a bracket 2 equipped with brushes 1 corresponding to a plurality of locations 14 to be coated.
for the object to be coated 9 and the grease holding part 13,
an applicator 10 that is capable of approaching and lowering, raising, and retracting; a grease holding section 13 that is provided with a plurality of grooves 12 that are arranged in correspondence with the brush 1 to hold grease; The groove 12 is filled with grease to be replenished, and the grease hopper 15 is pivotally supported to the mounting frame 41 so as to be able to swing downward in the front-rear direction.
The driving frame 16 pushes or pulls the mounting frame 41 so as to approach or retreat, and only the trailing edge of the grease hopper 15 in the moving direction slides into contact with the grease holding portion surface in conjunction with the pushing or pulling movement. This grease applicator includes a backward tilting mechanism R for tilting the grease hopper 15 backward.

(Function) When the bracket 2 approaches and descends toward the grease holding portion 13 and the brushes 1 come into contact with the corresponding grooves 12, the grease in the grooves 12 adheres to the brushes 1.

Next, the bracket 2 rises, moves away from the groove 12 and approaches the object 9 to be coated, and as it descends, the brush 1 comes into contact with the corresponding point 14 of the object to be coated, and the grease is applied to the point 14 of the object to be coated.

By sliding the grease hopper 15 into the groove 12, the groove 12 is replenished with the grease in the grease hopper 15.

This replenishment operation is performed by the mounting frame 41 that pivotally supports the grease hopper 15 being pushed or pulled by the drive frame 16, and along with this pushing or pulling movement. Since the backward tilting mechanism R tilts the grease hopper 15 backward, the front edge 15a of the grease hopper 15 in the moving direction is separated from the grease holding surface F, and only the rear edge 15b of the grease hopper 15 in the moving direction slides into contact with the grease holding surface F.

Excess grease that has built up on the grease holding surface F due to this sliding action is always scraped back into the grease hopper 15 by the rear edge 15b in the moving direction, and the grease is wasted and spills out of the grease hopper 15. Grease hopper 1
The grease in 5 is supplied to the grease holding part 13 without waste.

In this way, the bracket 2 equipped with a plurality of brushes 1
Furthermore, since the grease is applied by the movement of the grease hopper 15, expensive equipment such as a pressure feeder, pipes, etc. for pumping the grease are not required in this invention, resulting in a simple configuration.

(Example) Next, an example of this invention will be described based on the drawings.

As shown in FIG. 1 as a whole side view and as shown in FIG. Slider 5
The coating section 10 is configured such that an upper and lower cylinder 6 is fixed to the bracket 2 and an upper and lower piston 7 is attached to a support base 8 so that the bracket 2 can move forward, backward, and up and down toward the object 9 to be coated.

A holding plate 11 having a smooth upper surface 11a and having a plurality of grooves 12 is installed below the bracket 2.
2 is configured as a grease holding portion 13 that can hold grease.

The object to be coated 9 has a plurality of places to be greased 14 to which grease should be applied.
The positions of the plurality of grooves 12 provided in the grooves 12 are made to coincide with the positions of the areas 14 to be coated.

An inverted grease hopper 15 with a lower opening 15c is pivoted to the mounting frame 41 so as to be able to swing back and forth about the fulcrum pin 25 of the mounting frame 41, and the mounting frame 41 is pushed toward the groove 12, Groove 12
The drive frame 16, which is pulled back and moved backward, is moved in the front and back direction by the hopper moving cylinder 18 (using a rodless cylinder), and the grease hopper 15 is moved in conjunction with this pushing movement or pulling movement, respectively. A backward tilting mechanism R is provided to control the grease hopper 15 in a backward tilted posture so that the front edge 15a in the moving direction is lifted and only the rear edge 15b in the moving direction slides into contact with the grease holding part surface F.

That is, as shown in the front view in FIG. 3 and in the front view of the right half in FIG.
The support arm 26, into which the slider 24 is fitted so as to be movable up and down, and into which the fulcrum pin 25 fixed to the slider 24 is fitted, is attached to the hook bolt 28 and the wing nut 40.
, fix it to the hopper mounting plate 39 and attach it to the support arm 2.
The mounting plate 39 fixing the guide rod 6 is attached to the mounting frame 41, and the guide rod 17 is arranged in the front and back direction.
The mounting frame 41 and the drive frame 16 are loosely coupled via linear motion bearings 42 and 43, and rubber brakes 44 are attached to both ends of the bearing 43 of the mounting frame 41.

The lower part of the drive frame 16 is connected to the hopper moving cylinder 18 using a connecting plate 45, and connecting pins 46 parallel to the guide rod 17 are connected to the drive frame 16 and the mounting frame 41 at vertical positions sandwiching the guide rod 17. and 47
are loosely fitted together, and spacers 48 and 49 are fitted to the connecting pins 46 and 47 between the drive frame 16 and the mounting frame 41, and the drive frame 16 is moved toward the groove 12 as shown by the arrow in FIG. When moving, the mounting frame 41 is pushed and moved via the spacers 48 and 49, and the distance _l1 between the drive frame 16 and the mounting frame 41 becomes smaller, and when it moves away from the groove 12 as shown by the arrow in FIG. In this case, the mounting frame 41 is pulled and moved by the drive frame 16 via the connecting pins 46 and 47, so that the distance _l2 becomes larger. A pin 21 is attached to the left and right sides of the side frame 22, and the grease hopper 15 is fixed to the side frame 22 by the left and right pins 21, 21. The notch 30a,
A spring 23 is interposed between the lower surface of the slider 24, which is fitted into the pin 31 attached to the drive frame 16 and is vertically fitted in the guide groove 22b of the side frame 22, and the upper surface 22a of the terminal end of the guide groove 22b. mounting, slider 2
4 is pushed downward by a bolt 29 screwed into the hopper frame 20.

When in a stationary state, the grease hopper 15 is pushed downward by the elasticity of the spring 23 with the fulcrum pin 25 as a fulcrum, and the lower opening 1 of the grease hopper 15 is pushed downward.
Rubber scraper 50 attached to 5c

is pressed against.

In the state shown in FIG. 6 in which the drive frame 16 moves toward the groove 12 in the direction of the arrow, the mounting frame 41 is moved by the brake 44 that acts as a brake on the guide shaft 17.
As a result, the mounting frame 41 is pushed by the drive frame 16 via the spacers 48 and 49, and the distance between the drive frame 16 and the mounting frame 41 is reduced.
l ₁ becomes smaller.

As a result, the side frame 22 rotates counterclockwise around the fulcrum pin 25 by the arm 30, and its upper part tilts rearward in the direction of travel, and the grease hopper 15 also assumes a rearward tilted position, and the rear edge 15b in the direction of travel (rearward in the illustrated example). The scraper 50) moves forward while scraping the grease holding part surface F by the repulsive force of the spring 23, and the front edge 15a (front scraper 50) in the moving direction moves away from the grease holding part surface F.

In the state shown in FIG. 7 in which the drive frame 16 moves away from the groove 12 in the arrow direction, the head and neck lower portions 46 of the connecting pins 46 and 47 are moved by the action of the brake 44.
a and 47a come into contact with the rear surface of the mounting frame 41 in the moving direction, and the mounting frame 41 is moved, and the distance l ₂ increases.

As a result, the side frame 22 rotates clockwise around the fulcrum pin 25 by the arm 30, and its upper part tilts backward in the direction of travel, and the grease hopper 15 also assumes a backward tilted position, with the front edge 15a in the direction of movement facing the grease holding part. The trailing edge 15b in the moving direction moves away from the groove 12 while scratching the grease holding surface F.

In the above-described structure in which the backward tilting operation of the grease hopper 15 is not performed, as shown in FIGS. As shown in FIG. 10, the grease G that has piled up on the grease retaining part surface F is scraped off by the front edge 15a in the moving direction, and as it repeats the reciprocating motion in the arrow direction, it is deposited on both the front and rear outer edges of the grease hopper 15 as shown in FIG. It will accumulate in

As a result, the amount of grease in the grease hopper 15 increases, and the proportion of grease replenished into the groove 12 decreases.

However, due to the backward tilting movement of the grease hopper 15, the grease adhering to both the front and rear outer edges of the grease hopper 15 disappears, and the grease is not wasted in the groove 12.
Now we can replenish the amount.

Furthermore, the rearward tilting operation of the grease hopper 15 is performed simply by moving the drive frame 16 back and forth as described above, which has the advantage that no special power source for the rearward tilting operation is required other than the hopper moving cylinder 18.

The replenishing part 19, that is, the grease hopper 15, the hopper frame 20, side frame 22, slider 24, support arm 26, and arm 30 to which it is attached are attached to the wing nut 4.
0 and rotate the hook bolt 28 from the hopper mounting plate 39 around the pin 27, it can be immediately removed and separated from the hopper mounting plate 39. A push-out plate 32 is housed inside the grease hopper 15, and the push-out plate 32 is moved using a plate 33 projecting outward so that the grease inside can be pushed out.

The objects 9 to be coated are successively transported by a conveyor 34 in a direction perpendicular to the paper surface of FIG.
is inserted into a mounting bracket 35 and attached with a screw 37 to a mounting plate 36 attached to the lower end of the bracket 2, so that by replacing the mounting bracket 35 it is possible to accommodate objects 9 having different coating locations 14.

Since the grease applicator is constructed as described above, the bracket 2 is raised from the standby position shown in FIG. When reaching the upper part, bracket 2 descends and brush 1
comes into contact with the area to be coated 14 and the grease is applied.

During this operation, the mounting frame 16 moves forward due to the operation of the hopper moving cylinder 18, and the grease hopper 1
Grease on the lower surface 15a of 5 is replenished into the groove 12,
Next, this grease hopper 15 is moved back.

On the other hand, when the bracket 2 rises after coating, then retreats and descends again, the brush 1 comes into contact with the grease in the groove 12, and the grease adheres to the brush 1.
Return to the standby position shown in the figure.

(Effect of the invention) The grease applicator according to the invention is configured as described above, and as the grease hopper 15 slides into the groove 12, the grease in the grease hopper 15 is replenished into the groove 12. .

This replenishment operation is performed by the mounting frame 41 that pivotally supports the grease hopper 15 being pushed or pulled by the drive frame 16, and along with this pushing or pulling movement. Since the backward tilting mechanism R tilts the grease hopper 15 backward, the front edge 15a of the grease hopper 15 in the moving direction is separated from the grease holding surface F, and only the rear edge 15b of the grease hopper 15 in the moving direction slides into contact with the grease holding surface F.

Excess grease that builds up on the grease holding surface F due to this sliding action is always scraped back into the grease hopper 15 by the moving direction rear edge 15b, and the grease is wasted and spills out of the grease hopper 15. Grease hopper 1
The grease in 5 is replenished to the grease holding part 13 without waste, which is economical, and there is also the advantage that there is no spillage and the applicator is kept in a clean state.

Furthermore, since the grease application is performed by the movement of the bracket 2 equipped with a plurality of brushes 1 and the grease hopper 15, expensive equipment such as a pressure feeder, pipes, etc. for pumping the grease are not required. This design eliminates the need for this, resulting in a simpler configuration.
