Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
195 words
In mass-growing of seedlings in a greenhouse using seedling units of the type having a plurality of pots joined together in side-by-side relationship in an array to form a tray-like structure, where each pot is bottomless and comprises a plurality of resilient strips extending from the pot opening to converge towards the pot bottom side, the strips in use being rigid enough to hold and retain in use a lump of growth medium to support a seedling therein, a method of automatically inserting healthy seedlings together with growth medium into pots where seeds previously inserted into the growth medium did not germinate, said method comprising the steps of: scanning the array of pots in each tray aided by a control unit, to identify the locations of pots wherein an acceptable seedling is absent; automatically emptying the pot contents from said locations by using information regarding the identified locations; and automatically inserting replacement seedlings with lumps of growth medium in emptied pot locations by taking replacement seedlings from a replacement seedling tray, whereby with the processed seedling units all having acceptable seedlings and no pots with ungerminated seeds, the utilization of the greenhouse space is improved.

Claim 3
Dependent Claim
16 words
A method as in claim 1 wherein the step of scanning is performed by optical scanning.
Claim 4
Dependent Claim
16 words
A method as in claim 1, wherein the step of scanning is performed by capacitance scanning.
Claim 5
Dependent Claim
16 words
A method as in claim 1 wherein the step of scanning is performed by ultrasonic scanning.
Claim 6
Dependent Claim
16 words
A method as in claim 1 wherein the step of scanning is performed by infrared scanning.
Claim 7
Dependent Claim
21 words
A method as in claim 1 wherein the step of automatically emptying the pot contents comprises pneumatically emptying the pot contents.
Claim 8
Dependent Claim
45 words
A method as in claim 1 wherein the step of automatically emptying the pot contents comprises mechanically emptying the pot contents by causing a plunger move downwardly into a selected pot through control of said control unit, to empty the pot through its bottom side.
Claim 9
Dependent Claim
31 words
A method as in claim 7 including the step of arranging seedling units to be scanned on a conveyor, whereby the seedling units are scanned as they pass on the conveyor.
Claim 10
Dependent Claim
38 words
A method as in claim 8 wherein the step of automatically inserting a replacement seedling includes utilizing a seedling from a replacement seedling unit tray disposed on a second conveyor which is located vertically above said first conveyor.
Claim 11
Dependent Claim
40 words
A method as in claim 9 including the step of using a socket which is made to move downwardly to dislodge a replacement seedling from a replacement seedling unit tray into an evacuated pot vertically below on the first conveyor.
Claim 12
Dependent Claim
30 words
A method as in claim 10 including the step of hoisting an unscanned seedling unit tray from the first conveyor upwardly to the second conveyor, responsive to the control unit.
Claim 13
Dependent Claim
47 words
A method as in claim 10 including the step of admitting compressed air into the socket when it is moved up, so as to facilitate dislodging growth medium from the socket into an evacuated pot which is part of a seedling unit tray on the first conveyor.
Claim 14
Dependent Claim
33 words
A method as in claim 12 including the step of moving a seedling unit tray away from the second conveyor when such seedling unit tray is empty and has no more replacement seedlings.
