Definitions

  • the present invention relates to a method and device for cutting living tissue such as vegetable tissue, for instance for the purpose of grafting or pruning plants or trees, or for instance harvesting of fruit.
  • the invention comprises of cutting the tissue of for instance at least one first plant with a fluid jet, in order for instance to prepare a grafting process to be carried out in per se usual manner, which comprises of in fact combining the first and a second plant.
  • the method according to the invention can preferably be automated with a device according to the invention in a continuous (repeating) process to enable the realization of relatively large numbers of cutting processes, for instance for grafting purposes.
  • the method can preferably be carried out without any interruptions to speak of. It has not been found feasible in the prior art to realize a practically continuous process for great (er) numbers of successive grafting processes. The reason for this is that use is made in the known art of cutting tools such as knives to form incisions. The knives are on the one hand expensive and on the other always subject to wear. It is for this reason that attempts at automated grafting processes for larger numbers of plants never came to anything due to the still occurring regular interruptions for the purpose of replacing knives.
  • cutting processes based on cutting tools such as knives also have other drawbacks which decrease the speed and reduce efficiency, i.e. the transfer of germs via the knives.
  • the transfer of germs via the knives must be countered in the known art by cleaning the knives regularly, even if these knives do not then need to be replaced, i.e. when the knives are for instance not yet worn.
  • the additional disruptions for cleaning the knives result in still further reduction in the number of successful grafting processes per unit of time, even when they are carried out manually.
  • the present invention has for its object to reduce, and preferably obviate the drawbacks of the prior art in the field of for instance the grafting of plants, for which purpose there is provided according to the invention a method and a device as defined in the appended claims, in particular the independent claims.
  • interruptions for replacing worn knives can be reduces, if not minimized.
  • a grafting process wherein in an embodiment of the invention both pieces of plant material are treated (cut) with a jet of fluid, the use of conventional cutting means such as knives can even be wholly avoided.
  • the transfer of germs can further be reduced, if not avoided, particularly and additionally by an adequate cleaning of the fluid if it is reused.
  • Fig. 1 shows a perspective view of a configuration 1 forming part of a device according to the present invention for realizing the method according to the invention
  • Fig. 2 shows a cross-sectional side view through a more comprehensive part of the device according to the invention, a detail of which is already shown in fig. 1;
  • Fig. 3 shows a side view corresponding with fig. 2 with partly cut-away parts and with additional and/or alternative components and elements;
  • Fig. 4 is a schematic bottom or top view of the operation of the device shown in fig. 1-3;
  • Fig. 5 shows a detail designated with arrow V in fig. 3.
  • Fig. 1 shows a perspective view of a configuration 1 of a (part of a) device 11 according to the invention for realizing the method, likewise according to the present invention.
  • This configuration 1 comprises a first gripper 2 which is suitable and adapted to grip a stem or stalk or other part of a first vegetable tissue shown by way of example as plant 6 in figure 2.
  • a spray nozzle 4 is directed at first gripper 2, or at least at the vicinity thereof, at a predetermined angle which can amount for instance, though not exclusively, to 45 ° .
  • Spray nozzle 4 serves to form at least one incision and preferably even a cut with a jet of fluid, and via a conduit 8 is in operational connection with a pump 5 which feeds spray nozzle 4 with a fluid via conduit 8.
  • the fluid can comprise water or another liquid. It is however also possible to consider using gases to form a fluid jet.
  • Spray nozzle 4 is fixedly attached to a holder (not shown) to the side of gripper 2 and can be detached from the holder.
  • the holder, and therewith spray nozzle 4 can be arranged in stationary position.
  • the first gripper 2 move relative to the holder, preferably in a direction along spray nozzle 4, so that an incision can be made, with a jet of fluid to be generated by spray nozzle 4, in the stem or stalk of the first vegetable tissue of plant ⁇ , this plant 6 herein being gripped by first gripper 2, or it can even be cut through completely.
  • the first gripper 2 is stationary ' and a holder with spray nozzle 4 fixed therein can be moved along reciprocally in front of the gripper. It is also possible to realize both relative movements .
  • the conduit arranged between pump 5 and spray nozzle 4 is preferably flexible or at least bendable.
  • a fixed conduit 8 can suffice.
  • the spray nozzle 4 is arranged in stationary position.
  • a second gripper 3 is also arranged. This can serve to grip a stem or stalk of the same plant 6, or to grip a branch or other part of another, second plant tissue 7.
  • a fluid jet acts on the stem, stalk, branch etc. of plant tissue 6 by means of spray nozzle 4, this part of the plant tissue can be held fast on either side of a formed incision or cut by the individual first gripper 2 and second gripper 3.
  • the shown figures relate however to an embodiment wherein the second gripper 3 is used to bring a (part of a) second plant or vegetable tissue 7 into the vicinity of parts of the plant 6 or plant tissue gripped by first, gripper 2 and treated by the jet of fluid from spray nozzle 4. If first gripper 2 and second gripper 3 are then brought sufficiently close together, as shown on the left-hand side in figures 2 and 3, a connection can be established between the plant ⁇ or plant part gripped by first gripper 2 and treated with the jet of fluid from spray nozzle 4 and the (part of a) second plant 7 gripped in second gripper 3.
  • a clip 49, bracket, holder or other assist means known per se in the prior art can be made of a clip 49, bracket, holder or other assist means known per se in the prior art.
  • Clip 49 can however optionally also be arranged manually. Modification of such clips 49 or brackets, in order to make them suitable for automatic placing, is not precluded either, at least not in respect of the prior art brackets or clips which must be arranged manually.
  • pump 5 must be considered capable of generating a considerable pressure for the fluid jet which must act via spray nozzle 4 on a part of the plant gripped by first gripper 2.
  • a pressure to be generated with pump 5 can be as high as 2000 to 3000 bar, although this is only stated by way of a non-limitative example. Other values of the pressure to be generated with pump 5 which must be deemed at least adequate for the intended application can be determined with tests for diverse species of plant and applications.
  • Fig. 2 shows a side view in vertical section of a device 11 according to the present invention, with a number of the configurations 1, shown essentially in fig. 1, in connection with additional components and parts according to the present invention.
  • Figure 3 shows a more comprehensive view of an embodiment of a device 11 according to the present invention.
  • Device 11 comprises particularly a central shaft 9 which is hollow and arranged in stationary position relative to a base 10.
  • a first turntable 17 is mounted for rotation about bearings 18, 19.
  • a number of the first grippers 2 is disposed on first turntable 17.
  • First turntable 17 can be rotated around central shaft 9 by means of a drive comprising a belt (not shown) trained round a wheel 20.
  • first grippers 2 are co-displaced in a rotating movement which is indicated in figure 4 as a circular path 21.
  • This path 21 is defined in a curve disc 22 fixedly mounted on central shaft 9.
  • First grippers 2 are mounted on a block 23 having thereon a leg 24 protruding into a curve of curve disc 22.
  • Blocks 23 are arranged on slide rods 25, which protrude through first turntable 17. Blocks 23 with first grippers 2 thereon are thus moved around central shaft 9 in a movement imposed by the first turntable.
  • grippers 2 can be displaced up and downward in height direction relative to first turntable 17 using slide rods 25 depending on positions taken up along the path or trajectory 21 of first grippers 2, as can be seen clearly from comparison of the design of curve disc 22 on the left and the right in figures 2 and 3, wherein the first grippers on the left in figures 2 and 3 are positioned higher than on the right in these figures.
  • the first and second grippers 2, 3 comprise normally open arms 32, 33, wherein the grippers can be energized with sliding blocks 34, 35 acting on arms 32, 33.
  • the sliding blocks 34 associated with the first grippers are coupled to legs 24 by means of a coupling rod 36 in order to move sliding block 34 forward or rearward relative to slide rods 25 and, depending on a position taken up along trajectory 21, to thus selectively open or close the arms 32 of first grippers 2.
  • a drive shaft 12 which is mounted in bearings 13 and 14 and which is connected on the underside thereof to a drive element, in the embodiment shown here a belt (not shown) trained round a wheel 15.
