Description

Filler for large fruit containers size.

Object of the invention

The present invention relates to an apparatus or filler device, specifically designed for filling large containers used in certain types of fruit, such as melons, watermelons and the like.

The object of the invention is to achieve that fruit access the sine of the container in a smooth way, that is in absence of blows that could damage the fruit, and in a way automated that does not require the participation of labor.

Background of the invention

As is known, fruits like those previously These are distributed in large containers, usually boxes prismatic-rectangular cardboard, whose base is joined or formed by a pallet, so that these containers, once full, they are handled with a forklift, a pallet truck or Similary.

To fill the containers, they usually use conveyor belts that lift the fruit to the level of the mouth of them, from where they fall to their inside. Since these containers have a considerable height, that can exceed the meter, the blow that occurs in the fruit when falling from such height, it often causes damage to the same, with the consequent economic damage.

Trying to solve this problem, usually an operator deposits the fruit by hand gently on the bottom of the container, which involves a considerable physical effort, on all considering that in the specific case of watermelons they can easily exceed 10 kg of weight, which generates back pain workers who may eventually end up in spinal injuries.

In addition the filling is slow since the Fruit feed rate should be adequate to the capacity of the worker to be able to receive them one at a time and deposit them on the bottom of the container.

Description of the invention

The filler that the invention proposes resolves from the problem was fully satisfactory before exposed, in the different aspects commented.

To do this, more specifically, said filler materializes in a support of suitable dimensions to be able to receive in its breast the container integrated in the corresponding pallet, support that supports a pair of parallel and conveniently motorized rollers on which a canvas or element is wound similarly capable of being located at the level of the mouth of the container at the moment when the latter is loaded, or unrolling as it receives said cargo, until it reaches the bottom of the
container.

While one of the ends of the aforementioned canvas is fixed directly to the corresponding roller, the edge opposite it is through some ribbons or braces, both are roll and unwind on their corresponding rollers in Function of filling needs.

This way and once the canvas has reached the bottom of the container or the vicinity of it, it produces the winding of the same at its opposite end to the cited braces, with which the fruit is poured at the bottom of said container through the ample space left between the braces repeatedly cited.

As a complement to the structure described, provided that the filling maneuvers are carried out in a manner automatic, with the collaboration of weight, volume or by fruit counters, so that such detectors cause the drive of one and another roller, in the way convenient, and as the load is deposited on the canvas of fruit, so that the level of it on said canvas is always keep below the mouth of the container.

Logically the mobility of the rollers will be variable depending on the type of fruit to be handled, and the canvas can be fixed to the rollers, as previously stated, or by braces for each of them.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1.- Shows, according to a representation schematic in perspective, a large container filler for fruit, made in accordance with the purpose of this invention, in a vacuum situation, that is to say in a situation prior to Start of container loading.

Figure 2.- Shows a similar representation to the previous figure, in which a container is properly coupled in the heart of the filler and he begins to receive the fruit.

Figure 3.- Shows a similar representation to figure 2, but in a more advanced phase of container loading or container.

Figure 4.- Shows a representation of his similar to that of figures 2 and 3, in a loading terminal phase of the container

Figure 5.- Shows, finally, and according to a representation similar to that of the previous figures, the recovery phase of the canvas once the container filling

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the filler that the invention proposes is constituted from a support (1), of any configuration appropriate, able to receive within it, with the collaboration of a conveyor belt or any other means, a container or large container (2), of those normally used for the marketing of watermelons, melons and the like.

In any case in the mentioned support (1) defines a wide upper mouth that is framed by a pair of parallel rollers (3-3 '), on which a tarpaulin (4) capable of sealing said majority is wound mouth, canvas that according to the preferred example of practical embodiment of the invention is fixed by one of its ends to one of the rollers (3), while the other roller (3 ') does with the collaboration of braces or ribbons (5) capable of generating in certain moments a wide window (6) between the canvas (4) and the inside the container (2).

As previously said rollers
(3-3 ') will be motorized independently, so that the movement of one of them is completely foreign to the other, and the corresponding motors will be controlled by a robot or similar element, which receives information through sensors or appropriate detectors, not represented in the drawings, of the weight or volume of the fruit (7), or by means of counters of the number of said pieces, so that the system acts on the motors based on the information received regarding the access of the fruit on the canvas (4), which will be produced as conventional by means of a conveyor belt or by any other similar appropriate means.

According to this structuring, the Filler operation is as follows:

From the situation shown in Figure 1, in which the canvas (4) is mostly rolled on the rollers (3-3 '), offering a surface curved-concave for the reception of the fruit (7), in the breast of the support (1), specifically under said canvas (4), is place the container or container (2) to be filled, which like the fruit (4) You can access the filler with a ribbon contest conveyor or by any other means.

As the fruit (7) reaches the filler, the canvas (4) is descending by developing the same of one and / or another of the rollers (3-3 '), being at a certain point, as shown in figure 3, in which occurs the majority development of the roller (3 ') so that the braces or ribbons penetrate into the container (5), as shown in Figure 4.

At that time, in which the canvas will have arrived or it will be in the immediate vicinity of the container or container (2), produces the winding of the canvas on the roller (3) contrary to the braces (5), so that in its ascent it acts as a spout which gently deposits the fruits on the bottom of the container to through the wide window (6) defined by the braces (5), as in turn shows figure 5.

In this way a smooth discharge is achieved, in total absence of risks of damage to the fruit and with a minimum labor force participation, of course without the least physical effort that may involve some damage to operators.

It only remains to point out finally that the filler it can be used in isolation or be integrated into a fruit treatment facility, in which they participate calibrators, cleaners, etc., all for the fruit in question.
