Abstract

line for processing horticultural products, comprising a tank along which the horticultural products are pushed by a fluid current, on which said horticultural products can float freely, and an apparatus for processing the horticultural products, comprising at least one alignment matrix, provided with a base platform, which can be submerged at a predefined section of said tank, and with a plurality of mutually parallel partitions, which are extended at right angles from the upper face of said platform and, when said platform is submerged in the predefined section, at least rise above the free surface of the predefined section, each pair of said parallel partitions, which can be arranged along the movement direction of the fluid current, defining a respective channel for automatic forced alignment for the horticultural products, pushed toward the predefined section by the fluid current, wherein the at least one alignment matrix is a floating alignment matrix.

Claims

1. A line for processing horticultural products, comprising a tank along which the horticultural products are pushed by a fluid current, on which said horticultural products can float freely, and an apparatus for 5 processing the horticultural products, comprising at least one alignment matrix, provided with a base platform, which can be submerged at a predefined section of said tank, and with a plurality of mutually parallel partitions, which are extended at right angles from the upper face of said platform and, when said platform is submerged in the predefined section, at 10 least rise above the free surface of the predefined section, each pair of said parallel partitions, which can be arranged along the movement direction of the fluid current, defining a respective channel for automatic forced alignment for the horticultural products, pushed toward the predefined section by the fluid current, wherein the at least one alignment matrix is a 15 floating alignment matrix.

2. The processing line according to claim 1, wherein each pair of said parallel partitions has the same center distance, chosen so as to correspond substantially to the transverse space occupation of the horticultural products that float on the free surface of the fluid current, for their alignment one by 20 one along each one of said channels.

3. The processing line according to claim 1 or 2, wherein the center distance between each pair of said parallel partitions can be adjusted at will, for adaptation to any variation of the transverse space occupation of the horticultural products that float on the free surface of the fluid current. 25

4. The processing line according to one or more of the preceding claims, wherein said apparatus comprises adjustment means for adjusting the density of said matrix for its floating at a first vertical height, during the alignment of the horticultural products, and the subsequent transition to a second vertical height, which is greater than the first vertical height, for the 30 partial lifting of said parallel partitions and the settling of the horticultural products within said channels, and vice versa.

5. The processing line according to claim 4, wherein said adjustment means comprise a pneumatic circuit, which is affected by a dispenser of compressed air and leads to said matrix, for sending on command 5 compressed air within said matrix, which is at least partially hollow, with a consequent increase in the internal pressure and density, said circuit being provided with at least one discharge valve, for expelling on command the compressed air with a consequent decrease in the internal pressure and density. 10

6. The processing line according to one or more of the preceding claims, wherein said apparatus comprises elements for guiding the movement of said matrix, within said respective tank, between the first vertical height and the second vertical height.

7. The processing line according to claim 6, wherein each one of said 15 guiding elements is constituted substantially by a lateral bar, which is arranged at a respective side of said platform and is provided with at least one corresponding slider that can be coupled slidingly with a respective track provided along the internal lateral surfaces of said tank.

8. The processing line according to one or more of the preceding 20 claims, wherein said apparatus comprises an assembly for moving a head between at least one collection position, in which it substantially faces and is proximate to said matrix, and an unloading position, in which said head faces and is proximate to a container for collecting the horticultural products, said head comprising means for picking up and retaining the horticultural 25 products, which can be activated at said collection position and can be deactivated at said unloading position.

9. The processing line according to claim 8, wherein said pickup and retention means comprise a plurality of walls that are normally arranged vertically, are formed by said head and are spaced substantially according to 30 said center distance, which is preferably adjustable, between said pairs of parallel partitions, and respective retractable transverse elements, which can move between at least one active configuration, which can be activated upon reaching said at least one collection position, in which said matrix is pushed downward by said head and said walls are interposed between the aligned 5 horticultural products, replacing said parallel partitions, and at least one passive configuration, which can be activated upon reaching said at least one unloading position, in which said walls face and are proximate to the bottom level of the collection container, in said active configuration said transverse elements protruding transversely from the space occupation of said walls for

10.mechanical interference with the fall of the horticultural products as a consequence of the subsequent lifting of said head and its transfer toward said unloading position, in said passive configuration said transverse elements being retracted toward said walls, for the free release of the horticultural products in the respective collection container. 15 10. The processing line according to claim 9, wherein each one of said transverse elements is shaped by at least one active portion of at least one membrane, which can be inflated on command for its transition from said passive configuration to said active configuration.

11. The processing line according to claim 10, wherein each one of 20 said membranes is coupled in a lower region to a respective said wall, which has a substantially laminar shape, and can be inflated on command for transition from said passive configuration, in which it has a substantially laminar shape and is substantially aligned vertically with the respective said wall, to said active configuration, in which it has an increased volume and a 25 preferably cylindrical shape, respective mutually opposite active portions of each pair of adjacent membranes cooperating for mechanical interference with the fall of the horticultural products.
