GROWING SYSTEMS AND METHODS

Abstract

A growing system is described where plants are grown in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked out. The containers may be provided with one or more of the following services: power, power control, heating, lighting, cooling, sensing, data logging, growing, water and nutrients. The provision of these services within individual containers rather than across the system as a whole, allows for flexibility in storage whilst reducing cost and inefficiency and enables multiple crops to be grown in a single area.

[0034] FIG. 10 is a schematic perspective view of the uprights of the grid of the storage system, the uprights 16 carrying services for onward transmission to the containers, the system comprising the containers of FIGS. 5, 9a, and 9b.

[0035] As shown in FIGS. 1 and 2, stackable containers, known as containers 10, are stacked on top of one another to form stacks 12. The stacks 12 are arranged in a framework structure 14 in a warehousing or manufacturing environment. FIG. 1 is a schematic perspective view of the frame structure 14, and FIG. 2 is a top-down view showing a single stack 12 of containers 10 arranged within the frame structure 14. Each container 10 typically holds a plurality of product items (not shown), and the product items within a container 10 may be identical, or may be of different product types depending on the application.

[0036] The framework structure 14 comprises a plurality of upright members 16 that support horizontal members 18, 20. A first set of parallel horizontal members 18 is arranged perpendicularly to a second set of parallel horizontal members 20 to form a plurality of horizontal grid structures supported by the upright members 16. The members 16, 18, 20 are typically manufactured from metal. The containers 10 are stacked between the members 16, 18, 20 of the frame structure 14, so that the frame structure 14 guards against horizontal movement of the stacks 12 of containers 10, and guides vertical movement of the containers 10.

[0037] The top level of the frame structure 14 includes rails 22 arranged in a grid pattern across the top of the stacks 12. Referring additionally to FIGS. 3 and 4, the rails 22 support a plurality of robotic load handling devices 30. A first set 22a of parallel rails 22 guide movement of the load handling devices 30 in a first direction (X) across the top of the frame structure 14, and a second set 22b of parallel rails 22, arranged perpendicular to the first set 22a, guide movement of the load handling devices 30 in a second direction (Y), perpendicular to the first direction. In this way, the rails 22 allow movement of the load handling devices 30 in two dimensions in the X-Y plane, so that a load handling device 30 can be moved into position above any of the stacks 12.

[0038] Each load handling device 30 comprises a vehicle 32 which is arranged to travel in the X and Y directions on the rails 22 of the frame structure 14, above the stacks 12. A first set of wheels 34, consisting of a pair of wheels 34 on the front of the vehicle 32 and a pair of wheels 34 on the back of the vehicle 32, are arranged to engage with two adjacent rails of the first set 22a of rails 22. Similarly, a second set of wheels 36, consisting of a pair of wheels 36 on each side of the vehicle 32, are arranged to engage with two adjacent rails of the second set 22b of rails 22. Each set of wheels 34, 36 can be lifted and lowered, so that either the first set of wheels 34 or the second set of wheels 36 is engaged with the respective set of rails 22a, 22b at any one time.

[0039] When the first set of wheels 34 is engaged with the first set of rails 22a and the second set of wheels 36 are lifted clear from the rails 22, the wheels 34 can be driven, by way of a drive mechanism (not shown) housed in the vehicle 32, to move the load handling device 30 in the X direction. To move the load handling device 30 in the Y direction, the first set of wheels 34 are lifted clear of the rails 22, and the second set of wheels 36 are lowered into engagement with the second set of rails 22a. The drive mechanism can then be used to drive the second set of wheels 36 to achieve movement in the Y direction.

[0040] In this way, one or more robotic load handling devices 30 can move around the top surface of the stacks 12 on the frame structure 14 under the control of a central picking system (not shown). Each robotic load handling device 30 is provided with means for lifting out 38, 39 one or more containers or containers from the stack to access the required products. In this way, multiple products can be accessed from multiple locations in the grid and stacks at any one time.

[0041] FIG. 4 shows a typical storage system 1 as described above, the system having a plurality of load handling devices 30 active on the stacks 12.

[0042] FIGS. 1 and 4 show the containers 10 in stacks 12 within the storage system. It will be appreciated that there may be a large number of containers in any given storage system and that many different plant or crop varieties may be grown in the containers in the stacks 12.

[0043] FIG. 5 shows an individual container 10 for growing plants. The plants are grown on growing means 13 such as matting or soil located in the containers 10. Beneath the matting 13 the container may comprise a reservoir 54 (not shown) the reservoir containing water and/or plant food suitable for the plant being grown in the container.

[0044] The containers 10 are held in stacks by co-operating surfaces on adjacent containers 10. The containers 10 of FIG. 5, additionally comprise connection means 40 positioned at the intended co-operating surfaces of the containers 10. The connection means 40 may comprise electrically conductive layers deposited on the co-operating surfaces of the containers 10 or may comprise sprung-loaded contacts or springs as contacts or any other connection means capable of carrying power between two or more containers 10. Furthermore, the connection means 40 may comprise carbon loaded rubber contacts capable of carrying signals between two or more co-operating containers 10 in a stack.

[0045] The connecting means 40 shown in FIG. 5 comprise releasably latching connectors capable of carrying power, fluids (such as water and fertilizers) and other services or utilities required in the plant growing system

[0046] Individual containers 10 may comprise power supply means for supplying power to, for example, heating means, cooling means, data logging means, communication means and/or lighting means 60. Each individual container 10 may further comprise power control means for controlling the power to the or each service and controlling the power to other containers 10 in the stack 12 if power is to be transmitted to adjacent containers 10 in the stack 12. It will be appreciated that containers 10 comprising power control and control means are not limited to powering heaters, coolers or lights. Anything requiring power may utilise the power supply means. The power supply means may comprise batteries or may comprise means for transmitting power from an external power source through connection means 40 on the containers 10 or via the uprights 16 of the framework structure. Non-contacting methods of power transmission may also be used, for example magnetic induction or RF induction and optical methods.

[0047] FIG. 5 shows in detail a container 10 suitable for growing plant means. The container comprises lighting means 60 which may radiate light of a predetermined wavelength suitable for growing a desired crop. Furthermore, the container 10 comprises fluid supply means 52 which when activated, may sprinkle a predetermined amount of water on the crops growing in the container 10. The power to the lighting means 60 and the fluid supply to the sprinkling means 52 are routed through the container 10 via routing means 17 that run along one side of the container 10. The container is further provided with connecting means 40 to enable services to be routed up a stack 12 of containers 10 when the containers 10 are located in the growing system.

[0048] It will be appreciated that although in FIG. 5 the routing means are shown as mounted on the container 10, it is possible to form a container 10 such that the container comprises mouldings suitable to act as routing means 17.

[0049] FIGS. 6a to 6d show a further forms of container 10 from the stack 12, the container 10 comprising various configurations of lighting means 60. As shown in FIGS. 6a and 6b, the lighting means 60 may comprise a lid containing suitable bulbs, LEDs or any other suitable form of lighting 60. The lid may be removably attached to the container 10 and fold away during removal of the container 10 from the stack 12.

[0050] Alternatively, as shown in FIG. 6c the lighting means 60 may be provided in the base of a container 10 to light the container 10 below in the stack 12.

[0051] Furthermore, as shown in FIG. 6d the container 10 may be lit from a point external to the container 10, for example from the uprights 16 of the grid or the ceiling of the warehouse containing the storage system. As can be seen in FIG. 6d, positioning the lighting means 60 on the uprights 16 of the framework requires the sides of the container 10 to be removed. In essence this form of container is a plant growing tray having supports only at the corners, to allow the container 10 to be stacked on top of other containers 10 and to support containers 10 above.

[0052] Individual containers 10 may further comprising data logging means and communication means for transmitting data recorded to a remote central data logging device. The data logging means comprises sensors suitable for monitoring the conditions in the container 10, for example the temperature, any gas emission, for example as a result of decomposing fruit, and humidity. The data logging means and communicating means enable the content and condition of individual containers 10 to be monitored. Furthermore, knowing information about specific containers 10 in the stacks 12 in the system enables the condition of the storage system as a whole to be monitored. It will be appreciated that the type and method of communication may be but need not be limited to WiFi. Any suitable form of communication protocol or method may be used.

[0053] Individual containers 10 in the stack 12, may further comprise heating and/or cooling means and temperature monitoring means for monitoring the temperature in the container 10. The heating means may comprise flow of hot fluid via direct means, for example hot air, or indirect means, for example radiator means or may further comprise electrical heaters or electromagnetic induction heaters.

[0054] The cooling means may comprise Peltier coolers or may comprise flow of cold fluid via direct means, for example cold air or via indirect means, for example radiator means, including ice slurry compressor driven.

[0055] In this way, the temperatures of individual containers 10 may be controlled and varied depending on the content of the individual container 10. If the contents of the container need to be chilled, then the individual container can have a temperature of 5 degrees C. maintained rather than requiring a portion of the stacks 12 in the storage system to be maintained at a predetermined temperature by space heaters and coolers. It will be appreciated that these are examples only and any suitable form of heater or chiller may be used to achieve the desired effect.

[0056] It may be preferable for air to be blown across the containers 10 within the stacks 12 of the plant growing system. This may be achieved by generating an airflow throughout the system either utilising fans or other airflow means.

[0057] 5

[0058] FIGS. 7a to 7d show a further form of container 10 from a stack 12, the container 10 comprising fluid supply means 52 and further comprising a fluid reservoir (not shown). The contents of the container 10 may require water to be supplied thereto. Accordingly, the container 10 is provided with a reservoir that may be filled with a liquid or gas. In order to fill the reservoir 54, the container 10 may be removed from the stack 12 by the robotic load handling device and taken to a location in the system where the reservoir can be topped up as required. As shown in FIGS. 7a and 7b water and nutrients may be supplied via a sprinkler system 52 in a lid portion of the container 10. Alternatively, as shown in FIG. 7c, sprinklers 52 may be located in the base of the container 10 to provide water and/or nutrients to the plants in the container 10 below in the stack 12. In a further example, as shown in FIG. 7c, a container lid 72 comprising fluid supply means is removably attached to the container 10 and folded away during removal of the container 10 from the stack 12.

[0059] FIG. 7d shows an alternative form of container 10 in which the fluid supply means are routed via the uprights 16 of the framework. This again requires the sides of the container 10 to be removed. In essence this form of container is a plant growing tray having supports only at the corners, to allow the container 10 to be stacked on top of other containers 10 and to support containers 10 above.

[0060] It will be appreciated that the uprights 16 of the grid of the growing system may carry any of the services referred to herein or alternative services for onward transmission to the containers 10 by wires, cables or pipes or any other suitable means.

[0061] UK Patent Application Nos GB1518091.2 and GB1518115.9, from which the present application claims priority, detail systems and methods of routing services through containers 10 and framework structures and are hereby incorporated by reference.

[0062] FIGS. 8a and 8b show a service portion of the growing system described above. For clarity only a portion of the framework structure is shown with a representative number of containers 10 shown in a stack 12 within the framework. A portion of the containers 110 located within the system comprise growing means only in preparation for use. A portion of the containers 10 in the system comprise plants that have become too large for the spacing regime in which they were originally planted. Accordingly, one function of the service area of the system may be to thin out containers 10 comprising overcrowded plants out by picking a proportion of plants from an overcrowded container 10 to replant in a container 110 comprising growing means only.

[0063] A robotic picking device 100 may be provided to fully automate this task. However, it will be appreciated that the task may be performed manually by operatives at the service area of the growing system.

[0064] FIGS. 9a and 9b show a further form of container 10 for use in the growing system. During the life cycle of the crop grown in the system the crop concerned may reach a height whereby it is protruding from the top of the container 10. The container shown in FIGS. 9a and 9b is a spacer container 10 that acts so as to allow the plant 150 to continue to grow in the system despite reaching such a height. The spacer container 10 may be placed over the plant and act as a support for any container 10 placed above in the stack 12 of containers 10. The spacer container 10 may comprise plastics material that allows light to pass therethrough. Furthermore, the spacer container 10 may comprise services routed as described for a normal container 10 above.

[0065] FIG. 10 shows two of the spacer containers 10 described above located in a stack above a container 10 carrying a plant 150 of a substantial height when compared with that of a container 10. FIG. 10 further shows the uprights 16 of the growing system carrying lighting means 60 and watering means 52. Furthermore, FIG. 10 shows a container 10 comprising utility supply means being supplied via routing means 17 from the base of the growing system.

[0066] It will be appreciated that the spacer container 10 may be provided with releasable latching mechanisms to allow the spacer container 10 to be attached to the container 10 underneath. This may be required should a load handling device 30 be required to pick up a container 10 having a spacer container 10 mounted thereon. However, it will further be appreciated that alternative forms of load handling devices may be used to enable tall plants 150 to be handled in standard sized containers 10.

[0067] In use, seeds or seedlings are planted in the growing means within each container 10. The container 10 is provided with water or food as required for the plant contained therein to grow. The containers 10 are placed in stacks 12 within the storage system by the load handling means 30. The propagation of the plants is monitored either remotely by sensing means located within the system or by periodically removing containers 10 from the system to inspect the crops. The containers 10 are removed from the system by load handling devices operating on the substantially horizontal grid structure mounted on the framework. A target container 10 is picked from the system and transported by the load handling device to the service area. The load handling device positions the target container 10 on a conveyor loop comprising driven roller means or other suitable moving mechanism capable of moving the target container around the conveyor loop 120.

[0068] Whilst the container 10 is on the conveyor loop tasks may be performed, for example crops may be picked, seedlings may be thinned out, fertiliser may be added, the tasks being performed manually by operatives or robotically under the control of a centralised computerised utility.

[0069] Once the required tasks are completed the container 10 may be collected by a load handling device and placed back in a stack 12 within the growing system.

[0070] It will be appreciated that in this manner a large number of actions may be performed automatically that would normally be labour intensive and time consuming. Additionally, use of appropriate sensing means can ensure that each variety of plant within the system may receive the optimum growing conditions for that variety. In this way yield may be increased in an efficient manner.

[0071] Given the highly automated and controlled nature of the system a large number of uses are envisaged. Some of these are described below but should not be considered limiting.

[0072] The system may be used for development of new variants of plants, for example, or if optimal growing conditions for given variants are being established then the use of the system will require continual monitoring and all conditions within each container will require separate parameters to be checked and the contents regularly inspected. The amount of water, nutrients and light will need to be closely monitored and varied accordingly. This will require many containers to be removed, inspected and replaced at intervals. Advantageously, this can be achieved in the present system as the process of sensing, monitoring and removal of containers 10 from the system is highly automated.

[0073] If the system is to be used for mass production of given plants or crops, the cost of production needs to be minimised and therefore the required parameters for optimum growth will have previously been established. Therefore, the lighting, water, nutrients and temperature required for each plant or crop variety will be fixed at the beginning of the growth cycle. The containers will only be removed from the storage system every 3 to 10 days for the seedlings to be re-spaced and then ultimately harvested and the containers 10 re-seeded.

[0074] Advantageously, it is possible for both types of uses to be accommodated in a single storage system. A portion of the containers 10 may contain crops for mass production, a portion of the containers may contain products under development or new variants being monitored and optimal growth protocols being established.

[0075] It will be appreciated that a portion of the system may be partitioned by suitable partition means

[0076] In the examples described herein, it will be appreciated that not all containers 10 comprise all the services described. Furthermore, some containers, particularly if used for mass production, may not require any services other than the appropriate levels of light, water and nutrients. Conversely, for containers 10 being utilised in research and development or trials, more of the sensing and monitoring means may be required in each container.

[0077] In the case of a research and development container, at regular intervals the container or containers 10 are removed from the stacks 12 by the load handling device 30 and taken to an inspection port within the system. The condition of the plants is checked and nutrients or water added to the container as required. If the plants within the container still require time to achieve maturity, the container 10 is returned to the stacks 12. If the plant has grown sufficiently and the crop is ripe, the plants or crops are removed and the container 10 is cleaned and replanted and then returned to the stacks 12.

[0078] In the case of mass production, the relevant containers 10 may not be removed for inspection, but may only be removed when the crop is expected to have reached maturity.

[0079] The sensor means provided within the containers 10, monitor the condition of the plants growing therein. Whilst a schedule of maintenance of the plants in the containers 10 may be used, it will be appreciated that the sensors may trigger a container 10 being removed from the stacks 12 outside of the maintenance schedule. For example, if a container 10 contains growing mushrooms but the mushrooms are over ripe a sensor may detect a gas associated with food ripening and the container 10 may be removed outside of the maintenance schedule for inspection.

[0080] Certain greenhouses operate in an atmosphere with elevated levels of CO2. It will be appreciated that in these situations, suitable gas sensing means would be able to monitor and control the levels of CO2 accordingly.

[0081] It will be appreciated that many crops may be grown in such mechanised greenhouses. These include but are not limited to mushrooms, chillies, herbs, and lettuce. In some places, where energy is abundant but water scare this kind of system could also be used to grow cereal crops and other living things. Whilst the embodiments described here refer mainly to plant growth either for mass production or research and development purposes, it will be appreciated that any living organism, plant, animal or fungi could be grown in such a storage system. For example, the storage system could be used for the growth of fish, chickens, oysters, and lobsters. Additionally, the system could be used for GM trials, pharmaceutical trials, the storage of wine that needs specific maturing conditions, or cheese that need careful temperature and humidity control.

[0082] It is an advantage of this system of growing crops, that multiple crops may be grown in a single location, as different containers 10 may contain different crops. Furthermore, growing the plants in containers 10 prevents the spread of disease through a large crop as disease, blight, fungus or other plant related problems will be confined to individual containers 10. Whilst it should be possible to limit the infestation from the outside environment through filters in the system warehouse, any breach of this could be contained in individual containers, such that plant related problems could be minimised.

[0083] It will be appreciated that the storage system comprises a large number of containers 10 arranged in stacks 12. In one embodiment of the invention, the storage system comprises containers 10 of different categories dispersed within the system. For example, there may be empty containers 10, containers 10 growing plants, containers 10 containing goods to be stored, containers containing services such as power supplies or communications means, containers 10 comprising heating means, containers 10 comprising cooling means, containers 10 comprising goods requiring liquids and/or light.

[0084] It will be appreciated that some containers 10 may contain one or more of the services or devices referred to above. For example a container 10 with a reservoir 54 may also be provided with lighting means 60.

[0085] The lighting means 60 may take the form of LED lights or fluorescent tubes or any other suitable form of lighting.

[0086] The provision of data logging and condition monitoring means in containers 10 within the stacks 12 enables a map of the condition and topography of the system to be generated that would not otherwise be possible unless specific containers 10 were removed and examined.

[0087] Furthermore, providing services to specific individual containers 10 either via the uprights 16 or via container-to-container contacts, enables goods having different requirements to be stored within the same storage system without resorting to portioning the system and separating goods with different requirements in to separate sections of the grid.

[0088] Additionally, connections between containers 10 and communications between containers 10 and stacks 12 will generate a knowledge base of the storage system in real time that will assist in the event of a power outage for example, that will aid in possible disaster recovery. The alternative would be to empty all the containers and rebuild the stack which would be inefficient and costly.

[0089] It will be appreciated that all containers 10 may be removed from the stacks 12 by the load handling devices 30. No container 10 is fixed in a position and all contacts are makeable and breakable between the containers 10. Furthermore, containers 10 requiring services being passed through the uprights 16 are not fixed to the uprights 16 in any way. Any suitable make and break connection may be used.

[0090] It will further be appreciated that individual containers may be provided with one service, a selection of services or all service described. Furthermore, the services listed should not be regarded as limiting. Any form of service that is capable of being carried or transmitted to a container 10 may be envisaged.

[0091] In one embodiment of the invention, given for example only, the containers 10 comprise trays on which the plants are grown. The trays are approximately 10001400 mm. The trays comprise a frame, tall enough to allow the plants to grow to their natural harvesting height. In the specific embodiment, trays are stacked up to 20 m tall or more. Each tray is lit, either from lights attached to the top frame of the tray, from the base of the tray above or from lights in the grid as shown in example form only in FIGS. 6a to 6d above. All processing (planting, harvesting, pruning, spraying and potentially watering) is undertaken at specialised work stations with good ergonomics and potentially robots or other automation.

[0092] It will be appreciated that a plurality of different lighting arrays may be used. For example different arrays may be used during the early part of the plant's growth than to the end of plant growth. In the beginning stages, focusing all light on the plant and reducing the waste of lighting the surrounding soil would be preferable. Separate arrays may be utilised or a portion of lights may be switched off. Therefore, the lighting means 60 may be moveable with reference to the crop growing in the container 10. For example, should the crop grow in height, the level of the lighting means 60 may be raisable and lowerable relative to the height of the crop in the container 10. Furthermore, the growing system may comprise lighting means 60 in some or all of the containers 10, the length of time the lighting means 60 is operable being controllable and variable. Furthermore, the method of growing organisms may comprise the step of varying the length of time the lighting means (60) is operable, to simulate an appropriate day length for the plant in the container (10).

[0093] In a further embodiment, the plants may be grown upside down and lit from below. Advantageously, this would reduce the energy expended by the plant to move water and nutrients against gravity and may make some species grow faster.

[0094] The main reason for removing plants from the storage system to re-pot or re-space them such that maximum use is made of the lighting provided. A key advantage is that such handling can be made using automated means which can be fully utilised 247, thus making it very capital and labour efficient. Inspection can also be done by automated means, which can be expensive.

[0095] In a further embodiment, it may be advantageous to move the plants to the inspection stations used 247, rather than having continuous monitoring in every container.

[0096] In a further embodiment, sections of the storage system may be partitioned from the remainder of the growing system. For example, should a portion of the system require properties different from the rest of the system, it would be possible to partition a number of stacks 12. It will be appreciated that the partitions may be of a permanent fixed nature, or alternatively the partitions may comprise openable and closeable shutter systems to enable a more flexible partitioning system.

[0097] It will also be appreciated that the partitioning may have additional advantages, for example, partitioning enables sections of the storage system to be isolated from other sections, for example different portions of the system can be maintained at different temperatures. Furthermore, in the case where the system is used for such plant growing uses, there may be advantages in having different gaseous atmospheres in different portions of the system. For example, at different points in the growing cycle of certain crops, it may be advantageous for the crop to be exposed to different levels of CO2 in the atmosphere. This may be achieved by partitioning the system.

[0098] Furthermore, although the embodiments of the invention described above, and shown in the Figures, detail systems in which the containers 10 are all of a substantially identical size and shape, it will be appreciated that this need not be the case. As described in UK Patent Application No. GB1506364.7 filed 15th Apr. 2015, incorporated herein by reference, it will be appreciated that such a system may be configured to handle containers 10 of multiple sizes by use of load handling devices 30 of differing sizes capable of lifting and moving containers 10 of multiple sizes.

[0099] Many variations and modifications not explicitly described above are also possible without departing from the scope of the invention as defined in the appended claims.
