Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a lubricant supply device for a slat conveyor.

Conventional equipment of this kind has a tank containing lubricant above the upper part of the slat conveyor, and the lubricant is supplied from the outlet of this tank to fall onto the conveyor surface as appropriate, and is transferred to and from the conveyor surface. This prevents wear caused by the bottom of the containers rubbing against each other and collisions between containers caused by the movement of the conveyor.

However, in the above method, the lubricating liquid is supplied independently of the movement of the conveyor, so even if the conveyor stops, the lubricating liquid continues to be supplied, making it difficult to uniformly supply the lubricating liquid to the surface of the conveyor. Moreover, the excessively supplied liquid falls directly downward from the conveyor, resulting in the use of a large amount of lubricating liquid, which is extremely uneconomical.

This invention eliminates the drawbacks of the conventional methods described above, and can supply lubricating liquid uniformly to the surface of the conveyor. Furthermore, it is possible to recover and reuse excess lubricating liquid, thereby providing an economical lubricating liquid supply. The purpose is to provide equipment.

In order to achieve the above object, a lubricant supply device according to the present invention includes a coating roller having a large number of punch holes on the outer circumferential surface on the lower surface of an endless slat conveyor mounted almost horizontally on a machine frame. The applicator roller is rotatably supported in a lubricating liquid storage tank that is open at the top so that its lower half is immersed in the lubricating liquid, and the front and rear upper ends of this tank in the direction of movement of the conveyor are disposed in contact with each other from below. A base end portion of a lubricant saucer whose tip extends below the end of the conveyor is fixed to the edge, and the saucer or the tank is supported by a bracket attached to the machine frame. be.

Examples of the present invention will be described below.

In Fig. 1, reference numeral 1 denotes an endless horizontal slat conveyor mounted between a pair of sprockets 4 (the other drive sprocket is omitted) attached to a machine frame 3 at a predetermined interval. A container 2, such as a beer barrel, which is moved in the direction of the arrow and placed upright on the surface of the upper part 1a, is transferred.

On the surface of the lower portion 1b of the conveyor 1, a plurality of holding rollers 5 and a coating roller 6 are arranged near the sprocket 4 so as to be in contact with each other from below. As shown in FIG. 2, the application roller 6 is
The peripheral wall is provided with a metal plate 8 having a large number of punch holes 7 on the outer peripheral surface, and the width W is formed to be approximately the same as the transfer width of the conveyor 1. It is rotatably supported by engaging with a support groove 13 cut out in the opposing wall surface of a rectangular lubricant storage tank 12 with an upward opening so as to be immersed in a lubricant 14 such as the above.

As shown in FIG.
5 is fixed, and the distal end of this saucer 15 extends below the end of the conveyor 1 to receive the lubricant 14 falling from the conveyor 1 and collect it into the tank 12. . Therefore, the saucer 15 is formed to gradually slope downward from the distal end toward the proximal end.

The tank 12 integrated with the saucer 15 is fixed to the machine frame 3 by a bracket 10.

17 is a drainage pot provided at the bottom of the tank 12;
18 are pillars provided on both sides of the conveyor 1 in the moving direction;
19 is a guide member for the container 2 attached to the support column 18.

Next, the operation of the above embodiment will be explained.

When the conveyor 1 is moved, the lower part 1b of the conveyor rotates the coating roller 6 disposed below it due to contact friction. As a result, the liquid contained in the punch holes 7 in the lower half immersed in the lubricating liquid 14 of the roller 6 adheres to the surface of the holes 7 in a thin film form and rises, coming into contact with the surface of the lower portion 1b. At this time, the thin film is broken and the lubricating liquid 14 is applied to the surface. On this occasion,
Since a large number of punch holes 7 are formed on the outer peripheral surface of the roller 6, it is possible to supply the lubricant 14 in a uniform amount without variation.

After that, even if the conveyor 1 to which the lubricating liquid 14 was supplied as described above becomes the upper part 1a, and the container 2 is placed on the surface and transferred,
Wear caused by the friction between the surface of the conveyor 1 and the bottom of the container 2, and collision troubles between the containers 2 due to the movement of the conveyor 1 are avoided, and the containers 2 can be transferred smoothly.

The lubricating liquid 14 applied to the surface of the lower part 1b in the above may fall downward due to the subsequent movement of the conveyor 1, but such falling liquid 14 is received by the receiving tray 15, and is collected into the tank 12.

The present invention is as described above, and the application roller for supplying the lubricant has a large number of punch holes on the outer peripheral surface, and rotates in conjunction with the movement of the slat conveyor, while the conveyor is stopped. Since the lubricant is not supplied, the lubricant can be uniformly supplied to the surface of the conveyor without waste. In addition, excess lubricating fluid can be reliably caught in a saucer and collected in a tank for reuse, which has excellent effects such as being economical and reducing costs. It is.
