Description

DESCRIPTION

Selective product diversion system applicable to conveyor belts

TECHNIQUE SECTOR

The present invention refers to a mechanism that has been specially designed to be implemented at the exit of a conveyor belt, or between two conveyor belts of products, in order to allow selectively diverting said products moved by the belt.

The invention therefore falls within the field of automated product distribution systems.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, it is usual that in automated product transportation and distribution systems it is required that along a transportation line, the products that move along the line must be classified according to different criteria and therefore be extracted from said line selectively towards other conveyor belts.

Although there are mechanisms dedicated to this purpose, the problem with this type of mechanism is that they are complex and consequently expensive mechanisms.

EXPLANATION OF THE INVENTION

The selective product diversion system that the invention proposes satisfactorily resolves the aforementioned problem, based on a simple but highly effective solution.

For this, the device of the invention presents a structure based on a frame in which an elongated rectangular upper surface participates as a table, with a width according to the end of the conveyor belt after which the device is arranged, the surface on which the products will be moved, so that the larger sides of said table define the conventional entry and exit of the product movement mechanism, movement that It is carried out by rotating rollers, with the special feature that these rollers are integrated into mechanisms that can be rotated.

More specifically, it has been provided that a series of discoidal elements with a diameter according to the width of the belt/table are distributed longitudinally on the surface of the table, discs on whose surface the product displacement cylinders are distributed, which They will adopt a parallel arrangement, equidistanced, and whose width will vary depending on the chord of the arc that they form with the disk in which they are integrated.

Thus, in the normal working position of the belt, the discs will be arranged in such a way that all their cylinders are parallel to the longitudinal axis of the table, thus displacing the products that enter it, from one end of the belt to the other. said table in the same direction of advance as the belt that feeds the mechanism.

However, these discs will be associated with a vertical rotation axis that, through a transmission, allows them to rotate selectively in the horizontal plane.

In this way, when it comes to diverting a package or product, when the computer system for the automation of the mechanism detects, through the corresponding sensors, that a product must be diverted from the line at the point where the selective product diversion system, said system will activate the mechanism that rotates the discs, once the package is arranged on them, so that the rollers, when changing their angular position, and when they are activated again, will cause the displacement of the package transversally to the line, causing the package to be removed from the table at that point, either by gravity falling into a collection area, or by arranging another redirection/redirection conveyor belt laterally in correspondence with the end or lateral ends of the device. package recirculation.

Obviously, once the package has been diverted, the discs will return to their position normal work, in which its rollers are parallel with the longitudinal axis of the table, so that the rest of the packages can continue moving normally along the line.

In this way, a diversion mechanism is achieved that is simpler than existing mechanisms on the market, economical and consequently very interesting for the sector of automated product distribution.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of its practical embodiment, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 1.- Shows a top-side perspective view of a selective product diversion system made in accordance with the object of the present invention.

Figure 2.- Shows a profile view of the device of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the device is constituted from a frame (1) in which an elongated rectangular table (2) is established on top, whose larger sides (3-4) define the entrance area and main exit for the products or packages to be moved along a distribution line, so that the device is arranged at the exit of a conveyor belt, presenting a length according to the width of said conveyor belt, and can be located below from this another conveyor belt.

In any case, in correspondence with the smaller lateral ends, zones are defined Selective diversion (5-5') for packages.

Well, as previously mentioned, the table (2) is affected by an alignment of circular holes (6) with a diameter close to the width of said table, in which some discoidal elements play, hereinafter discs ( 7), in which the classic motorized and free cylinders or rollers (8) (8') are integrated, usually used in conveyor belts to move packages or products along them.

Due to the circular configuration of the discs (7) these rollers will have different lengths, to adapt to the chord of the arc that they form with the disc in which they are integrated so as to maximize the support surface with the packages, cylinders that will present all of them their parallel axes.

Thus, the rollers (8) will be activated by motors and transmissions (9) for each disc (7), so that when the discs (7) are arranged with the rollers aligned according to the longitudinal axis of the table, the drive of said rollers (8) will cause a longitudinal movement of the packages or products from the input end (3) of the table to the output end (4) thereof.

However, in accordance with another of the essential characteristics of the invention, provision has been made for the discs (7) to include a vertical rotation axis (10) associated with a transmission (11) linked to one or more electric motors (12). , so that from a series of sensors and control electronics the discs (7) can be rotated so that the rollers (8) are oriented to move the packages or products transversally to the table (2), that is to say, towards the exit zones (5-5'), all of this at the exact moment in which the package to be diverted is arranged on the discs, the rollers (8) being in charge, as was said, of ejecting/diverting said package. from the main distribution line.

As previously stated, once the package has been diverted, the discs will rotate 90° to return to their main working position, giving continuity to the belt again.

Finally, it only remains to point out that the table will include spheres (13) in the area that is not affected by the discs (7) that facilitate the movement of the packages on said surface.
