Description

Description
Machine for automatic selection of destalked grapes.
The present patent application for industrial invention relates to a machine used to clean destalked grapes to separate vegetation residues.
The present invention falls within the wine-growing sector, in which the grape harvesting process has been more and more automated over the years by using grape harvesting machines provided with stalk separator devices.
It must be noted that, after harvesting the grapes, it is necessary to clean the products, eliminating the so-called vegetal or green parts, which may consist in leaves, small fragments of leaves or stalks.
To that end several machines have been designed to select and discard the "green parts" that must be separated from the grape berries.
The first operation carried out after harvesting is the so-called "destemming" that provides for removing the berries from the stalk.
This operation is normally entrusted to automatic machines that are negatively impaired by the fact that some of the berries are accidentally smashed during their removal from the stalk, thus producing a considerable quantity of liquid juice that must be separated from berries and stalks.
The product obtained from these machines is sent to other machines designed to eliminate the green parts of the destalked product.
Different types of machines are currently used to separate grape berries from "green parts".
The first type of machine uses a parallel pair of overlapped rollers, each of them provided with a dense series of toothed disks in parallel position with suitable mutual distance.
The pair of rollers is situated downstream a belt feeder that transports the product to be processed, which is composed of berries and "green parts"; the berries fall in the space between the spaced series of parallel disks, and stalks, leave stems and stalk fragments are trapped in the teeth of the said disks and discharged on a suitable slide used to eject the rejected parts. The main inconvenience of this type of machine consists in the fact that the teeth of the said toothed disks are not able to carry out their function, that is to say the exact elimination of all the "green parts" of the product, in a satisfactory way; moreover, there is a high risk that the larger grape berries are partially or completely smashed during the passage of the said parallel series of toothed disks. Another inconvenience consists in the fact that some berries are ejected together with the "green parts", thus generating considerable product waste.
The second type of machine used for selection is provided with a device designed to generate an air jet, which is installed downstream a belt feeder that transports the product to be screened.
The said blower is fixed under the end side of the belt feeder in such a way that the air jet hits each grape berry or "green part" that goes over the end side and falls down into a collection tank. The air jet can be suitably regulated in terms of power, width and distance in such a way that, because of their light weight, the "green parts" are removed from the berries that, because of their heavier weight, fall on the bottom of the collection tank without being interfered by the said air jet.
The functional limits of this second type of machine derive from the fact that sometimes the difference in weight between grape berries and
"green parts" is very small and it is therefore difficult to select the parameters that determine the power and field of action of the air jet, which are of course responsible for good screening.
In the third type of machine the product is positioned on a suitable perforated grille that vibrates and makes the berries fall under the grille, passing through the holes, while the vegetation residues with higher dimensions than the holes remain above the grille, which operates as a sieve.
The main inconvenience of this type of machine consists in the fact that the holes tend to be partially or completely clogged by the green parts, thus requiring periodical interruptions of the machine to clean the grille.
The purpose of the present invention consists in devising a machine for automatic cleaning of destalked grapes, which is not impaired by the foregoing drawbacks, and is in particular able to select the grapes precisely, without smashing grape berries or originate excessive product waste.
These and other purposes have been achieved by the automatic machine of the invention, whose main characteristics are illustrated in the first claim.
The machine for automatic cleaning of destalked grapes of the invention comprises a belt feeder composed of a net with a dense series of meshes with suitable dimensions according to the type of grapes to be selected, The product to be selected is positioned on the belt feeder that is subjected to a vibrating action according to a preferred embodiment.
The grape berries pass through meshes of the net and fall under the belt, where a collection tank is positioned, while the green parts stay on the said belt or are trapped in the meshes of the net. The machine also comprises rollers with filiform brushes designed to clean the belt and eject small parts from the machine.
Some of the rollers are installed under the belt in such a way that the brushes may eject upwards the green parts that are trapped inside the meshes; a revolving roller with filiform brushes is installed at the end side of the belt to remove vegetation residues that may be trapped in the meshes regardless of the previous actuation of the brushes.
The revolving roller rotates in such a way that its peripheral speed has an opposite direction with respect to the belt in the point where the brushes interfere with the belt. Downstream the belt, the machine comprises a slide designed to convey the small parts and waste pieces towards a waste container, while the grape berries that fall under the belt are conveyed inside a collection tank where they are picked by traditional machines that feed the wine-making machines. For major clarity, the description of the machine of the invention continues with reference to the enclosed drawings, which are intended for purposes of illustration only and not in a limiting sense, wherein: - figure 1 is a diagrammatic side view of the machine of the invention;
- figure 2 is an axonometric view of the machine of the invention;
- figure 3 is a view of a traditional machine with vibration and drip trays that incorporates the cleaning machine of the invention. With reference to figures 1 and 2, the machine for automatic cleaning of destalked grapes comprises a frame (T) that supports a screening and feeding belt (1 ), which is basically composed of a net with a dense series of identical meshes (1 a).
The screening and feeding belt (1 ) is wound on a parallel pair of movement and support rollers (2) with horizontal axis, of which one is a driving roller and one is a driven roller, in such a way that an upper branch (1 b) and a lower branch (1 c) of the belt (1 ) create an intermediate space (A).
The space (A) contains a revolving roller (3) with filiform brushes provided according to an axis parallel to the axis of the pair of movement and support rollers (2).
The revolving roller (3) is designed to clean the screening and feeding belt (1 ) and eject upwards the "green parts" that are trapped in the meshes (1 a).
According to the operating principle of the machine of the invention, the product to be selected is discharged on the upper branch (1 b) of the screening and feeding belt (1 ), which transports the said product composed of grape berries and "green parts" towards the end side (1 d), where the upper branch (1 b) is wound around the end roller (2).
The belt (1 ) can be subjected to vibrations in order to favour the screening and fall of the grape berries transported on the belt (1 ) through the meshes of the upper branch (1 b) and then through the meshes of the lower branch (1 c).
The machine is provided with a discharge opening (4) situated under the belt (1 ) where the berries fall, under which a box is positioned to collect the selected product.
The smaller "green parts" tend to be trapped inside the meshes (1 a) of the screening and feeding belt (1 ), while the larger ones that do not pass through the meshes remain on the upper branch (1 b) of the screening and feeding belt (1 ).
When the said "green parts" go over the end side (1 d) of the belt (1 ), they fall onto a slide (5) that conveys them towards a waste collection container.
Under the screening and feeding belt (1 ) at the end side (1 d), the machine of the invention comprises a roller (6) provided with filiform brushes that rub against the lower branch (1 c) of the belt (1 ) in opposite direction with respect to the forward travelling direction of the lower branch (1 c). The function of the roller (6) is to remove the vegetation rests that may be trapped in the meshes of the conveyor (1 ) after going over the end side
(1 d).
Also these vegetation rests are projected by the said roller (6) towards and over the slide (5). In the machine of the invention vibrations may be imposed directly to the belt (1 ) or entire frame (T) of the machine, by means of traditional vibrators of eccentric type.
Finally, it must be noted that the machine for automatic cleaning of destalked grapes is designed to be fed by a traditional destemming machine installed upstream.
The cleaning machine of the invention can be incorporated in a traditional destemming machine, using in this case the frame and motor unit of the destemming machine.
Figure 3 illustrates an integrated solution of this type, in which the cleaning machine of the invention is housed inside a large bearing tank (V) provided at the entrance with a series of vibration and drip trays designed to feed the screening and feeding belt (1 ).
