Definitions

  • the present invention relates to a device and/or a method for protecting at least one agricultural or forestry product, such as trees and particularly saplings, from damage by for instance beetles, preferably prior to transport of the agricultural or forestry product.
  • the device can also relate to a method and device for subsequently packaging an agricultural or forestry product, such as a crop or trees, in a container.
  • control agents and/or protection agents has heretofore been performed manually, particularly when such agents are sticky or tacky, because, for instance in the case of wax for protection against determined species of beetles, the adverse effect on automated devices for application thereof is a significant problem.
  • agents which are difficult to process such as wax
  • use is always made in the relevant art of manual processing of such agents and manual application thereof on, in or at saplings or other agricultural or forestry products.
  • Packaging of particularly (saplings or) trees in the container has heretofore also only taken place manually.
  • the invention relates to a method and a device with elements, components and aspects which correspond to the method, wherein the method comprises of: applying wax on, in or at the agricultural or forestry product; and depositing the wax on at least a trunk or stem thereof.
  • the products can thus be and remain protected against harmful influences, such as pathogens, beetles and the like, during transport in the container - often a cardboard box.
  • a better protection can be achieved than if protection agents and control agents are deposited in the foliage or in a substrate, particularly when the phenomena to be controlled are for instance beetles.
  • the invention by no means precludes wax falling onto foliage or branches of the saplings and/or other agricultural or forestry products; what is substantially required however is that at least a considerable part of the wax comes to lie on the trunk or stem.
  • a high degree of automation can of course moreover be realized which can render manual processing of wax or other agent unnecessary in efficient, inexpensive and effective manner.
  • An embodiment of the method according to the invention can thus have the further feature of tilting the agricultural or forestry product relative to an upright position thereof to a tilted position thereof, in particular an oblique position thereof.
  • the agricultural or forestry products being tilted during depositing of the wax on a trunk or stem thereof it is possible to ensure that the agent comes to lie substantially only where it is desired, i.e. on, in or at the agricultural or forestry product, without adverse effects on a device for realizing the method.
  • the method according to the invention can comprise of: pouring wax over the agricultural or forestry product in a stream of wax.
  • Such a stream can contain a surplus of wax and be collected for reuse so that such an embodiment can still be very efficient, despite the advance assumption that much wastage will hereby occur.
  • a method according to the present invention can have the feature of applying the wax to the agricultural or forestry product in a spray of wax.
  • a spray can be applied in controlled manner and spray nozzles can be set into operation selectively, preferably when a sapling or another agricultural or forestry product is located in the vicinity of a respective spray nozzle.
  • Selective activation and deactivation of the spray nozzles in particular, but deactivation of a random embodiment of an applicator more generally, can reduce consumption of wax by interrupting emission of wax, particularly when no agricultural or forestry product is in the vicinity of a location of a stream or spray of the wax, for which purpose a detector or sensor can be provided and of which neither of the two publications recognized above as prior art give any indication.
  • WO-95/32620 in particular relates to carrying spray nozzles on conduits, which can optionally be heated, twice between rows of plants but gives no indication of deactivating the spray nozzles or other applicators in a space between plants in a series when the spray nozzles or applicators according to this disclosure are being moved along the series of plants.
  • a method according to the invention can comprise of: rotating the agricultural or forestry product about a longitudinal axis while pouring the wax thereon in the stream or applying the wax thereto with a spray.
  • rotating the agricultural or forestry product about a longitudinal axis while pouring the wax thereon in the stream or applying the wax thereto with a spray.
  • An additional or alternative embodiment of the method can further have the further feature, prior to applying wax on, in or at the agricultural or forestry product, of: selecting diseased or dead specimens of the agricultural or forestry product; and removing the diseased or dead specimens. Since a far-reaching degree of automation can be realized with the method, such an automated selection of diseased or dead specimens provides a further improvement in the sense that no diseased or dead specimens are subjected to the application of wax, wax is saved and no dead or diseased specimens are delivered to the place of destination, this without any human intervention at the location of origin. A further result is thus also an optimal degree of filling of the container without first packaging products which are already dead or diseased and wasting the associated space in the container.
  • the method can further have the feature that the selection comprises of: recording an image of at least one specimen of the agricultural or forestry product, and comparing a recorded image to a reference in order to select the diseased or dead specimens, wherein the reference is at least one from the group comprising: length, colour and portion of green leaf in a recorded image.
  • An alternative or additional embodiment can have the features of packaging the agricultural or forestry product in a container, comprising of: collecting the agricultural or forestry product on a transport plate; inserting the transport plate with the agricultural or forestry product thereon into the container; retracting the transport plate; and holding the agricultural or forestry product in place in the container.
  • the method can further have the feature here of providing a transport plate with dimensions substantially corresponding to inner dimensions of the container.
  • An alternative or additional embodiment of the present method can have the feature of cooling at least one of: the wax on the agricultural or forestry product after application thereof; and the agricultural or forestry product prior to and/or after application of the wax thereto. This results in the wax remaining on the agricultural or forestry product after it has been applied to the agricultural or forestry product.
  • the present invention also relates to embodiments of a device with features, elements and components corresponding to the method steps as already discussed above, and with the same advantages and/or features.
  • a similar consideration applies to another aspect, i.e. a container with at least one specimen of an agricultural or forestry product which is arranged therein using an embodiment of the method or device.
  • the applicator comprises a depositing opening and a receptacle opposite each other relative to the agricultural or forestry product, and further a feedback from the receptacle to the depositing opening.
  • a simple outflow opening can already suffice, wherein a receiving bin can be disposed opposite such an outflow opening relative to trees or other agricultural and forestry products positioned between the outflow openings and the receptacle.
  • the feedback is usable and useful for feeding back the excess of poured wax and still enabling application thereof to a tree or other crop.
  • the device can comprise at least one spray nozzle as addition or alternative to the stream of wax. If at least two spray nozzles are arranged in the device they can be positioned at least at two positions from the group comprising: one above another; opposite each other relative to the agricultural or forestry product; one after another in a direction of longitudinal movement of the agricultural or forestry product. A uniform distribution of wax for applying can thus be realized.
  • the device according to the invention can further comprise: a control connected to the at least one spray nozzle and configured to selectively activate and deactivate the spray nozzle. Savings can thus be made in the use or consumption of wax.
  • the control can be connected to a proximity sensor which is configured to generate and send a detection signal to the control when the agricultural or forestry product is located in the vicinity of the at least one spray nozzle.
  • a selective spraying process with the at least one spray nozzle can then be optimally adjusted to a situation where a sapling or agricultural or horticultural product is actually situated at the spray nozzle, so that excessive use or consumption of wax can be minimized.
  • Detecting the proximity of the agricultural and horticultural products relative to a sensor makes it possible, when a spray nozzle or other applicator moves along a row of (saplings or) trees or agricultural or horticultural products or the row is displaced along the applicator, to deactivate the applicator in an intermediate space and for a period of time corresponding to the space between the trees or agricultural or horticultural products, so that wax can be saved compared to a situation in which the applicator remains in continuous operation while the applicator moves along a row or vice versa (as in the prior art according to WO-95/32620, which in any case does not disclose that the applicator known therefrom can be deactivated during such a movement).
  • a device can have the feature of a conveyor for carrying the agricultural or forestry product along the applicator and depositing the wax in, on or at the product.
  • a conveyor for carrying the agricultural or forestry product along the applicator and depositing the wax in, on or at the product.
  • Fig. 1 to Fig. 18 show a sequence of steps in a possible embodiment of a method according to the present invention which can be realized with a device of which parts, components and elements are shown schematically;
  • Fig. 19 shows a device and method, wherein the application of wax to (saplings or) trees is shown in more detail;
  • Fig. 20 A to 20C show the operation of a conveyor in the device according to figure 19 at various stages.
  • Fig. 21, 22, 23 and 24 show schematic views of different embodiments of an applicator for applying wax to a (sapling or) tree.
  • Figure 1 shows a row 1 of saplings 2. Trees 2 have to be packaged in a box 4 as embodiment of a container in the sense of the present invention. At least one side 5 of the box is open.
  • the method and device according to the present invention are based on a transport plate 6 in combination with a slide 8 and optionally also upright edges 7 on transport plate 4.
  • a camera 3 is directed at the row 1 of trees 2, as shown in more detail in figure 2.
  • the camera records an image of the row 1 of trees 2, and so also of the individual trees 2.
  • Figure 3 shows an example of an image of trees 2 in a row 1 recorded with camera 3. Each of the trees 2 is compared to a reference. In the view of figure 3 the reference is a height of the trees 2, which is shown with broken line 9 in figure 3. Above broken line 9 there are good/bad indications 10; such an indication 10 for each of the trees 2. From left to right in row 1 the third and fifth trees 2 are substandard, this being established with the reference shown as broken line 9.
  • Figure 4 shows that the relevant trees 2 (the third and fifth in row 1 from left to right) are discharged in the direction of arrow A.
  • the relevant trees 2 have developed insufficiently, and are therefore possibly diseased or even already dead.
  • the relevant trees 2 can therefore be removed.
  • the positions opened up in row 1 of trees 2 are preferably filled again with healthy trees 2.
  • the function and operation of a selector in the sense of the present invention is thus shown with the views of figures 2, 3 and 4.
  • the selector has the main purpose of selecting and removing or discharging diseased and dead specimens or trees 2. These may also be trees which are simply too substandard to satisfy determined commercial criteria. Sale of trees can for instance be based on a minimal development and growth height thereof. The selected trees 2 are then not discarded as waste but can be taken back to a growing location in order to develop further.
  • the thus functioning selector can make use of a development or growth height as reference.
  • Other criteria can also be employed, such as the colour of leaves or needles (too much grey or brown can indicate disease or death).
  • Figures 5A, 5B and 5C show the operation of an applicator.
  • This comprises at least a gripper for gripping pots 11 with trees 2 therein in row 1.
  • the gripper then has to be configured to tilt trees 2 in the direction of arrow B in figure 5A.
  • Such a gripper then forms part of a tilting mechanism.
  • Figure 5B shows that a wax 12 is applied to a tree 2.
  • Wax is an embodiment of a protection agent or control agent, which is intended and acts to control beetles (or at least determined species of beetles) which could otherwise attack trees 2.
  • Use is made in figure 5B of a brush 13. It should however be noted that it is precisely the tilting of trees 2 in row 1 which enables wax to simply be poured onto trunks 14 of trees 2, as described below with reference to figures 19 and 20A-20C.
  • a quantity of wax 12 falls onto each trunk 14, while surplus wax can be collected under trunks 14 of trees 2 and fed back to an outflow to be applied again over a trunk 14 of a tree 2.
  • the row 1 of trees 2 can be tilted back again in the direction of arrow C in figure 5C, for which purpose the same gripper is preferably applied with which trees 2 in the row in figure 5A are also tilted in the direction of arrow B.
  • Figure 19 and figure 20 shows schematically a device 17 for realizing the steps in figures 5A, 5B and 5C.
  • Device 17 comprises a feed 18 over which blocks 20 with pins 21 thereon can be supplied. Trees are supplied in a tray and held up. Grippers engage the trees at the foliage part (or on or round a trunk), and the grippers are displaced laterally toward blocks 20 with pins 21.
  • Cameras 3 monitor and pass on information about each tree to the grippers. Rejected trees are placed in the opening between the transport tracks and fall onto a waste track. Approved trees are placed in blocks 20 with pins 21 and continue to a waxing device 23. In combination with a control (not shown) and the grippers these cameras 3 thus fulfil a selecting function as described with reference to figures 2-4.
  • Substrate 22 with a tree 19 or other agricultural or forestry product therein can be clamped between pins 21 and on blocks 20.
  • Blocks 20 arc carried over a transport track from feed 18 to an entrance of waxing device 23. After waxed trees have been packaged in boxes at station 36 the empty blocks return to filling positions, where the trees are supplied in trays and are gripped at grippers having in the vicinity thereof the cameras for selecting healthy trees to be waxed.
  • Waxing device 23 comprises a supply 24 which is connected via conduits 25 to outflow beams 26 out of which streams of wax 27 can flow.
  • Liquid wax with an additive of pigment is carried by means of pumps (not shown) from supply 24 to beams 26. Measures can be taken in supply 24 to keep the wax liquid, such as heating elements and/or more particularly also stirring or agitating members.
  • One or more than one of the beams 26 is provided and, in the case of two or more of the beams 26, these are preferably arranged at different heights. Wax can thus be applied to trees 19 of different lengths or heights after they have been placed in an oblique position.
  • a receiving bin 28 Arranged under beams 26 is a receiving bin 28 for collecting wax which has flowed out of beams 26 and has not adhered to one of the trees 19.
  • Stirring or agitating members are arranged in receiving bin 28 in order to keep the wax liquid.
  • wax can be purified, for instance in a conduit or component on the way to supply 24, and circulated so as to return to beams 26 and flow out over trees 19.
  • Supply of additional wax can take place at melting device 29, into which blocks of wax with pigment can be inserted, wherein a heating element 30 can be set into operation in order to melt the wax to be supplied.
  • the blocks 20 are carried with a rope conveyor 31 along wax flowing from beams 26.
  • Rope conveyor 31 further comprises a guide 32 along which move slide blocks 33.
  • guide 32 has a raised portion on the right-hand side, wherein blocks 20 come to lie in an oblique position as a result of the clamping between the ropes of rope conveyor 31 and slide blocks 33, as well as the orientation of guide 32.
  • waxing device 17 On an exit side of waxing device 17 trees covered with wax are disposed on blocks 20, with substrate 22 of trees 19 between pins 21. A gripper 35 is disposed between exit 34 of waxing device 23 and a schematically shown packaging device 36, which will be further described below.
  • waxing device 23 preferably also comprises screening means, such as chains or the like, in order to prevent wax flowing from beams 26 falling nowhere else than on trees 19. An exceptionally clean way of applying wax to trees 19 can hereby be realized.
  • rope conveyor 31 co-acts with additional ropes 37 and both rope conveyors rotate in the same direction but at different speeds, so that blocks 20 rotate about a longitudinal axis of trees 2.
  • the application of wax all around the trees is thus enhanced. Because more than a minimum of wax is poured out over the uees and the trees thus rotate about a longitudinal axis thereof, a crown or rosette of wax is formed (on the substrate) at the base of trunks of trees. As a result the frees are especially well protected at this location.
  • Figure 6 shows that a row 1 of trees 2 is placed on a transport plate 6 as also shown in figure 1.
  • the length of row 1 of trees 2 is the same as the width of transport plate 6 between the upright edges 7 thereof.
  • a standard conveyor or gripper 35 for the purpose of displacing row 1 of trees 2 in the direction of arrow D, and so onto transport plate 6, use can be made of a standard conveyor or gripper 35 in figure 19.
  • a stop 15 can be placed against transport plate 6 in the direction of arrow E as shown in figure 7.
  • Slide 8 can then be set into motion in the direction of arrow F in order to push the row of trees 2 against stop 15.
  • slide 8 is then moved back in the direction of arrow G in order to leave floor surfaces clear on transport plate 6 for the purpose of placing new rows of trees 2 thereon as shown in figure 9.
  • the slide 8 is set into motion in order to place trees 2 as compactly as possible against each other, as shown in figure 10.
  • the waxed trees are packaged in boxes in the manner shown in figure 19.
  • a row of trees is transferred to a plate 38 with lateral upright edge 39 and held in place with pins 42.
  • Rows of trees 40, 41 disposed adjacently of each other are offset relative to each other. Pins 42 thus fit with the least possible spacing between individual trees in a row 41.
  • a subsequent row of pins 42 in a retracted position holds the second row of trees 41 in place, after which the row of pins 42 which is extended in figure 1 (and which up to that point has held the first row of trees 40) is retracted from between the second row of trees 41. This process is repeated until the surface of plate 38 is filled with rows of trees 40, 41,..., and box 43 can be filled.
  • Plate 38 with the lateral upright edge 39 is pushed together with a pusher 44 into box 43 and, when plate 38 has been positioned in box 43, pusher 44 remains stationary while plate 38 is retracted. Once trees 40, 41 are in box 43, pusher 44 returns to a starting position together with or over plate 38.
  • transport plate 6 with trees 2 thereon is positioned at a box 4 and, as shown in figure 13, displaced into box 4 in the direction of arrow H in figure 13. It is noted here that the width of transport plate 6 corresponds to the width of box 4 so that box 4 is optimally filled.
  • the box 4 as embodiment of a container in the sense of the present invention can be a cardboard box.
  • Transport plate 6 is then retracted in the direction of arrow I in figure 14 while slide 8 is held stationary. Transport plate 6 is thus pulled out from under pots 11 of trees 2, wherein stationary slide 8 prevents pots 11 and trees 2 from co-displacing backwards and they remain in box 4. Once transport plate 6 has been fully retracted from box 4 in the direction of arrow I in figure 14, slide 8 is also retracted in the direction of arrow J in figure 15.
  • Flaps 16 of box 4 are then folded over the open sides 5 of box 4, as shown in figures 16 and 17, in order to produce a transportable closed box 4 such as that shown in figure 18.
  • Figure 21 shows an alternative or additional embodiment of or for an applicator 50 for applying wax to at least the trunk or stem of a sapling or other agricultural or horticultural product.
  • the applicator 50 comprises at least one spray nozzle, and in the shown embodiment even comprises six spray nozzles 51 in two rows 52, 53, each of three spray nozzles 51 one above the other, wherein rows 52, 53 are situated at a mutual distance in the direction of a transport of trees 2 with a schematically shown conveyor 54.
  • the spray nozzles can be arranged on a mounting plate 56.
  • a similar applicator 50 can be arranged opposite spray nozzles 51 relative to the trees 2 moving past, as shown in figures 22 and 23.
  • the trunks or stems of trees 2 can be long or less long, as shown in figure 21.

  • a selection of spray nozzles 51 in each row 52, 53 can be set into operation if or when proximity of a tree is detected at a row 52 or 53 by means of a detector 57, which can be connected for this purpose to a control 58 as shown in figures 21, 22 and 23.
  • This control 58 can send control signals to the spray nozzles in order to selectively activate (figure 22) or deactivate (figure 23) them.
  • Detector 57 can be configured to determine the height of trees 2 so as to activate spray nozzles 51 up to a desired height in row 52 or 53. Similar considerations can relate to the height of pots or cups 55, wherein the lowermost of the spray nozzles 51 in each of the rows 52, 53 can be activated or deactivated as pots or cups 55 move past. It can be an object here to also cover substrate in pots or cups 55 with wax and to even apply a layer of wax up to a short distance below the upper edge of the pots with trees 2 therein.
  • Trees 2 in pots can be transported in the direction of arrow N in cups with pots 55 therein by means of conveyor 54 and then, particularly in the vicinity of spray nozzles 51, be rotated about a longitudinal axis of trees 2 in the direction of arrow P.
  • One, two or more than two rows 52, 53 of spray nozzles 51 can be arranged.
  • Cups or pots 55 can be rotated at or in front of each row 52, 53 through an angle which is proportional to at least 1/n, wherein n is the number of rows 52, 53 with spray nozzles 51, so that each tree is wholly sprayed all the way around at least once by spray nozzles 51.
  • Figure 24 shows a valiant of an applicator 60, wherein two spray nozzles 51 are mounted on a U-shaped frame 59 rotatable about a shaft 61 in the direction of arrow R, i.e. opposite each other relative to tree 2.
  • Frame 59 on shaft 61 can be mounted for up and downward movement in the direction of arrow Q.
  • Cameras can additionally be arranged on frame 59 for selection of trees (and optional ejection of dead or diseased trees), or for detection of proximity of trees in order to activate and/or deactivate spray nozzles 51.
  • Frame 59 can be lowered (Q) over a tree 2 and rotated ® with spray nozzles in operation in order to cover at least a hunk or stem thereof with wax.
