Distributor apparatus for positioning individual pieces of growth medium into a tray

Abstract

The present invention relates to a distributor apparatus adapted for positioning individual pieces of a length of growth medium cut into pieces of suitable size into a propagation tray. The distributor apparatus comprises a plurality of distributor units configured to move between a loading position and an unloading position. Each distributor unit comprises an open-ended channel or cavity adapted for receiving a whole number of growth medium pieces. The distributor units, in a loading position, are positioned relatively to each other such that their open-ended channels or cavities are disposed in continuation to each other to form a receiving unit with an open-ended channel or cavity adapted for receiving a single length of growth medium pieces. The distributor units, when in an unloading position, are rotated, relative to their loading position, such that their open-ended channels or cavities are disposed parallel relative to each other.

(1) FIGS. 1-9 show still views of a first distributor apparatus in operation in accordance with various embodiments of the invention;

(2) FIGS. 10-11 show still views of a distributor unit in operation in accordance with various embodiments of the invention; and

DETAILED DESCRIPTION OF THE INVENTION

(4) FIGS. 1-9 show still views of a first distributor apparatus in operation in accordance with various embodiments of the invention. FIG. 1 shows the initiation phase of the loading operation, where an apparatus 400 produces a length of growth medium cut into pieces 12 of suitable size. The distributor apparatus 100 comprises a plurality of distributor units 210 (more specifically 12 distributor units) configured to move between a loading position and an unloading position. Each distributor unit 210 comprises an open-ended channel or cavity 212 adapted for receiving a single growth medium piece 12. The distributor units 210 are positioned relatively to each other such that their open-ended channels or cavities 212 are disposed in continuation to each other to form a receiving unit 200 with an open-ended channel or cavity adapted for receiving a single length 10 (FIG. 2) of growth medium pieces 12. A first displacement means is shown comprising a spade blade 310 (not visible, but is shown in FIG. 3), a first drive means 320, and a second drive means 330. The spade blade 310 is configured for fitting within a cutting groove 16 (FIG. 2) between two individual growth medium pieces 12. In FIG. 1, the first drive means 320 is shown in a retracted position with the spade blade positioned above a cutting groove between two individual growth medium pieces, and in FIG. 2, the first drive means 320 is shown in an extended position with the spade blade within said cutting groove. In FIG. 3, the second drive means 330 has moved the spade blade 310 towards the open-ended channel or cavity of the receiving unit 200, such that the single length 10 of growth medium pieces 12 (more specifically 12 growth medium pieces) has been positioned within the open-ended channel or cavity of the receiving unit 200.

(5) In FIG. 4, the second drive means 330 is has moved the spade blade 310 back to its starting position. In FIG. 5, the unloading operation is initiated. The single length of growth medium pieces has been divided into individual growth medium pieces by separating the distributor units 210 from one another. In FIG. 6, the distributor units 210 have been rotated relative to their loading position, such that their open-ended channels or cavities 212 are disposed parallel relative to each other. In FIG. 7, the distributor units 210 are aligned to be positioned correctly above the propagation tray 14. In FIG. 8, a piston unit 300 enters the open-ended channel or cavity 212 of each distributor unit 210, thereby releasing a single growth medium piece therefrom and into the propagation tray 14. The piston units may in one or more embodiments work independently from one another, or in groups. Thereby, a pattern of the growth medium pieces 12 are formed in the propagation tray 14, if e.g. a larger distance between the individual growth medium pieces 12 is needed to provide better growth conditions. In FIG. 9, the piston units 300 are retracted again, and the entire operation may be repeated.

(6) FIG. 10 shows a distributor unit 210, where the open-ended channel or cavity 212 of a distributor unit 210 comprises holding means 214 for releasably holding a growth medium piece when positioned therein. The holding means 214 is in a retracted position as necessary during the loading operation. In FIG. 11, the holding means 214 is in an extended position. The specific distributor unit shown is adapted for being positioned as the last distributor unit, i.e. the position farthest away from the apparatus adapted for producing a length of growth medium cut into pieces of suitable size. Hence, a stop means 216 (here a plate) is partly blocking the channel or cavity 212 such that growth medium pieces will not escape the open-ended channel or cavity of the receiving unit during the loading operation.

(7) FIGS. 12-14 show still views of a second distributor apparatus in operation in accordance with various embodiments of the invention. FIG. 12 shows distributor units 210 that are positioned relatively to each other such that their open-ended channels or cavities 212 are disposed in continuation to each other to form a receiving unit 200 with an open-ended channel or cavity adapted for receiving a single length of growth medium pieces. In FIG. 13, a part of the distributor units 210 have been rotated relative to their loading position, such that their open-ended channels or cavities 212 are disposed parallel relative to each other. In FIG. 14, all distributor units 210 have been rotated. The rotation is performed using a curved track 500.
