[0010] A preferred embodiment for carrying out the present invention will be described below with reference to the drawings. Note that this is merely an example, and the technical scope of the present invention is not limited to this. For example, in the following embodiment, for ease of understanding, the support part lifting device will be described as a wire lifting device 50, but the object to be lifted may be something other than a wire, such as a rail. In addition, although one agricultural crop management device 10 and one wire lifting device 50 are shown, in reality, multiple wire lifting devices 50 may be installed.

[0011] <Configuration of a Crop Management System> Figure 1 shows an example of a crop management system that uses a wire lifting device 50 according to one embodiment of the present invention. The crop management system 100 of this embodiment is composed of a hanging crop management device 10, a first wire (support part) 102A along which the crop management device 10 moves in a predetermined direction and on both sides of which rows S of crops C are placed, and a wire lifting device 50 attached to a second wire 102B located above the first wire 102A and at a position where it intersects with the first wire 102A.

[0012] The agricultural crop management system 100 is used to harvest agricultural crops, particularly vegetables and fruits that grow above the ground surface and have harvested products above the ground surface, such as peppers, tomatoes, mandarins, strawberries, eggplants, and cucumbers.

[0013] The crop management system 100 includes a first wire 102A for suspending the crop management device 10. The first wire 102A is supported by a pole erected from the ground, the structure of the greenhouse, or a member attached to the structure, and is positioned higher than the harvested crops, extending in a predetermined direction in which the crops C are planted.

[0014] Similarly, the second wire 102B for fixing the wire lifting device 50 is supported by a support pole erected from the ground, the greenhouse structure, or a component attached to the structure, and is positioned higher than the first wire 102A, and extends so as to intersect with the first wire 102A.

[0015] <Overall Configuration of the Crop Management Device> Next, the overall configuration of the crop management device 10 of this embodiment will be described. As shown in Fig. 1, the crop management device 10 is a hanging type crop management device 10 that moves in a predetermined traveling direction along the first wire 102A, and includes an engagement unit 14 that engages with the first wire 102A, a rotation unit 18 that has a rotation shaft (not shown) located directly below the first wire 102A and is rotatable relative to the engagement unit 14, a main body 12 on whose top surface the rotation unit 18 is provided, and in which an acquisition unit 30 that acquires harvested product C is provided in a movable space 20 provided on the traveling direction side, and a camera provided on the acquisition unit 30.

[0016] 2(B), a wire insertion portion 16 through which the first wire 102A is inserted is provided along the direction of travel in the engaging portion 14. The engaging portion 14 also includes a roller that engages with the first wire 102A, a wire moving motor that is controlled by a control portion (not shown) and rotates the roller about a rotation axis that extends in a direction perpendicular to the direction in which the first wire 102A extends, and a support member that supports these members.

[0017] The engaging portion 14 has two rollers arranged on both ends of the first wire 102A, but this is not limited to this and, for example, four rollers may be arranged, or a roller may be arranged below the first wire 102A so that the first wire 102A is sandwiched between the rollers.

[0018] The rotating unit 18 comprises a base portion connected to the support member of the engaging unit 14, a rotary motor fixed to the base portion, controlled by the control unit, and rotating around a rotary shaft (not shown) located directly below the first wire 102A, and a transmission portion to which the lower end of the rotary shaft is connected and which transmits the rotation of the rotary motor to the rotating unit 18.

[0019] A movable space 20 is provided in front of the main body 12, allowing the acquisition unit 30 to move up and down, rotate, and move horizontally (forward and backward). In the illustrated example, the movable space 20 is formed by leaving approximately the front left half of the agricultural product acquisition device 10 uncovered by the main body cover. A storage unit 40 for storing the harvest F acquired by the acquisition unit 30 is provided on the bottom surface 22 side of the movable space 20. When the storage unit 40 is full of the harvest F, a lid provided on the back surface 12D side of the bottom surface 12B of the main body 12 opens, and the container containing the harvest F is transported along a pair of rails.

[0020] The acquisition unit 30 includes a vertical member which is a long body extending vertically inside the main body 12, a lifting mechanism which raises and lowers the acquisition unit 30 within the movable space 20, a horizontal movement mechanism which moves the acquisition unit 30 back and forth horizontally within the movable space 20, and a rotation mechanism which rotates the acquisition unit 30 within the horizontal plane of the movable space 20.

[0021] The vertical member is provided with a lifting member that moves up and down relative to the vertical member, and a horizontal member is supported on the lifting member so as to be able to move horizontally (forward and backward). A vertical bracket is provided at the tip of the horizontal member so as to stand in the vertical direction, and a base portion is provided at the upper end of the vertical bracket.

[0022] A pair of rotary motors are provided on the upper surface of the base portion, and the rotation of these pair of rotary motors is controlled by a control unit via pulleys, motor gears, etc. (not shown) to move a pair of endless belts from the tip side to the base side on the opposing surfaces of a pair of gripping portions at the tip of the acquisition unit 30.

[0023] A camera is provided on the top surface of the base between the pair of rotary motors, and an LED light is provided on the tip side of the horizontal member between the vertical brackets.

[0024] The acquiring unit 30 includes a base, a pair of gripping units, and a cutting blade (not shown). The pair of gripping units grasp the stalk FS near the harvested product F of the agricultural product C or the harvested product F itself. Specifically, the pair of gripping units includes a rotary motor that is controlled by the control unit and drives the gripping units.

[0025] As described above, the control unit controls the pair of endless belts to move from the distal end to the proximal end on the opposing surfaces of the pair of gripping parts at the distal end of the acquiring unit 30, whereby the stalk FS (near the harvested product F) is grasped between the pair of gripping parts and cut with a cutting blade (not shown). For example, a cutting blade is provided on the distal end side of the pair of gripping parts, and, if necessary, also on the proximal end side of the pair of gripping parts.

[0026] The camera is fixed to the base and is controlled by the control unit to capture images of the rows S, crops C, and harvested goods F. If the camera were attached to the main body 12, it would be impossible to properly capture images of the capture position and harvest when the main body 12 rotates. However, according to the present invention, the camera is provided in the capture unit 30 rather than the main body 12, so that rotation of the main body 12 does not interfere with capture or harvesting. In addition, an LED light is provided, so the capture position can be captured in bright conditions.

[0027] Next, the storage unit 40 is provided below the movable space 20 and stores the harvest F acquired by the acquisition unit 30. The storage unit 40 includes, for example, a container unit, a fixed bottom, a movable bottom, and a drive unit. The container unit is formed in a box shape with at least the top open. Then, for example, when the container unit becomes full, it is driven under the control of the control unit, the movable bottom moves below the fixed bottom, the lid on the bottom side of the back of the main body unit 12 is released, and the container containing the harvest F is transported through the opening.

[0028] Furthermore, as will be described later, the crop management device 10 includes a battery (not shown) that serves as a power source for driving the crop management device 10, in addition to a control unit (not shown).

[0029] <Functions of the Control Unit of the Crop Management Device> Next, the functions of the control unit of the crop management device 10 of this embodiment will be described. The crop management device 10 includes a control unit, an analysis means, a movement position identification means, a horizontal position identification means, an acquisition unit control means, and a transmission / reception means, and controls the operation of the crop management device 10. The control unit is also communicatively connected to a camera, a wire movement motor, a rotation motor, an elevation motor, a horizontal movement motor, a pair of rotation motors, and a storage unit motor.

[0030] The analysis means analyzes the images of the row S, crop C, and harvest F captured by the camera, and determines whether or not the harvest F has formed. In detail, the analysis means uses, for example, well-known techniques such as deep learning and pattern matching on the images captured by the camera, and determines whether or not the harvest F has formed based on whether or not the detection accuracy exceeds a predetermined threshold.

[0031] When the analysis means determines that the harvest F has been harvested, the movement position identification means sets the harvest F as a target and moves the acquisition unit 30 so that the target is within a predetermined angle of view among the angles of view that can be captured by the camera. In detail, the movement position identification means controls the drive of the wire movement motor to move the agricultural crop management device 10 in the direction in which the first wire 102A extends, thereby aligning the horizontal (left-right) position of the acquisition unit 30 with respect to the target. In addition, the movement position identification means controls the drive of the lift motor to move the acquisition unit 30 vertically, thereby aligning the vertical (up-down) position of the acquisition unit 30 with respect to the target.

[0032] Once the moving position identification means has aligned the acquisition unit 30 horizontally (left and right) and vertically (up and down) relative to the target, the horizontal position identification means captures an image of the harvest F with a camera, acquires the image of the harvest F as point cloud data, and measures the size of the target harvest F and the distance to the harvest F.

[0033] Then, if the measured size of the harvest F is a predetermined size (for example, S size, M size, L size, etc., which is predetermined depending on the type of harvest F), the horizontal position identification means controls the drive of the horizontal movement motor to align the horizontal (front-to-back) position of the acquisition unit 30 relative to the target based on the measured distance.

[0034] In addition, the horizontal position identification means uses a camera to acquire an image of the harvest F, along with the harvest being held at the tips of the pair of gripping parts, detects the difference in position from the harvest F, and controls the drive of the wire movement motor, rotation motor, lifting motor, or horizontal movement motor to correct the position of the acquisition unit 30 so that the fruit stalk FS near the harvest F is placed between the pair of gripping parts.

[0035] The acquisition unit control means corrects the position of the acquisition unit 30 using the horizontal position identification means so that the fruit stalk FS near the harvested product F is sandwiched between a pair of gripping units, and then controls the drive of a pair of rotary motors to sandwich the fruit stalk FS near the harvested product F between a pair of endless belts (not shown) that move from the tip end to the base end.

[0036] Then, when the pair of gripping parts grips the fruit stalk FS near the harvested product F, the acquiring part control means controls the drive of the cutting blade motor to rotate the cutting blade and cut the fruit stalk gripped on the shaft by the pair of gripping parts. Alternatively, the fruit stalk FS may be cut by a pair of rotary blades that rotate in response to the rotation of the endless belt.

[0037] In addition, once the acquisition unit control means cuts the stalk FS, the horizontal position determination means controls the drive of the horizontal movement motor to move the acquisition unit 30 holding the harvested product F in the horizontal direction (front-to-back direction) away from the crop C (towards the vertical member) and place it above the storage unit 40.

[0038] Then, when the horizontal position identification means positions the acquisition unit 30 holding the harvested product F above the storage unit 40, the acquisition unit control means cuts the fruit stalk FS as described above and drops the harvested product F into the storage unit 40.

[0039] The transmitting / receiving means may transmit, for example, the number of harvested products F obtained, position information of crop management device 10 (for example, position information calculated from the movement distance based on the drive of the wire movement motor relative to the initial position), etc. to an external device (for example, a terminal operated by a user) at a predetermined timing. The transmitting / receiving means may also receive from the external device settings indicating the size of the harvested products F to be obtained, information indicating the drive timing of crop management device 10 (for example, the harvesting rule schedule), reference data referenced when the analysis means and horizontal position identification means make judgments, etc.

[0040] The control unit includes a processor, memory, storage, and communication unit (not shown), which are connected by a bus. The processor is configured, for example, by a CPU (Central Processing Unit) and performs various processes by reading and executing various programs stored in the memory. The memory stores the programs executed by the CPU and is configured, for example, by a ROM (Read Only Memory) or RAM (Random Access Memory).

[0041] <Configuration of Wire Jumping-Up Device> Next, the configuration of the wire jumping-up device 50 will be described with reference to Figs. 2 to 5. Fig. 2 is an external perspective view showing the wire jumping-up device of this embodiment, where (A) is a view showing the wire in a lowered state, and (B) is a view showing a state in which a crop management device passes through the wire jumping-up device along the wire in the state of (A). Fig. 3 is a view showing the wire jumping-up device of this embodiment, where (A) is a front view and (B) is a partially enlarged portion of (A). Fig. 4 is a side view showing the wire jumping-up device of this embodiment, and Fig. 5 is a side view showing the range of motion of the arm of the wire jumping-up device of this embodiment.

[0042] As shown in these figures, the wire lifting device 50 is a wire lifting device for a hanging type crop management device 10 that moves in a predetermined direction along the first wire 102A, and the wire lifting device 50 is installed on a second wire 102B that is located above the first wire 102A at a position that intersects with the first wire 102A.

[0043] The wire lifting device 50 comprises a square pipe-shaped main body 52 whose bottom surface 52D is fixed to the second wire 102B, fixing portions 54A, 54B provided on the bottom surface 52D of the main body 52 and fixed to the second wire 102B, a roughly U-shaped cover body 60 provided to cover the top surface 52C and both side surfaces 52E, 52F of the main body 52, a pair of arms 72A, 72B rotatably provided on both side surfaces 60B, 60C of the cover body 60 and raising and lowering the first wire 102A in accordance with the weight of the crop management device 10, and a pair of biasing mechanisms 70A, 70B provided between the pair of arms 72A, 72B and both side surfaces 60B, 60C of the cover body 60, respectively, and biasing the tips 74A, 74B of the pair of arms 72A, 72B upward.

[0044] The width W1 (see FIG. 2(B)) of the square pipe-shaped main body 52 is, for example, 50 mm, and the height is also 50 mm. The thickness T1 (see FIG. 3(B)) of the main body 52 is set to, for example, 2 mm.

[0045] The width of the upper surface 60A of the cover body 60 (see FIG. 2(B)) is set to, for example, 64 mm, and the height H1 (FIG. 2(A)) of both side surfaces 60B, 60C of the cover body 60 is set to, for example, 43.5 mm. In this embodiment, a reinforcing round pipe 56 (see FIGS. 2(A) and 3(A)) is provided inside the main body portion 50, and the diameter of the round pipe 56 is set to, for example, 48.9 mm. As shown in FIG. 3(B), the thickness T2 of the portion where the main body portion 52 and the round pipe 56 overlap is set to, for example, 1.45 mm.

[0046] As shown in Fig. 3(A), the pair of arms 72A, 72B have receiving portions 76A, 76B for receiving the first wire 102A provided slightly above one end portion 74A, 74B so as to be approximately perpendicular to the arms 72A, 72B. Furthermore, a height H2 from the center of bolts 80A, 80B (described later) to the receiving portions 76A, 76B of the pair of arms 72A, 72B is set to, for example, about 90 mm. Furthermore, although not shown, the maximum play of the pair of arms 72A, 72B, and the amount of overlap of the receiving portions 76A, 76B when the arms 72A, 72B are tilted, are set to, for example, about 1.5 mm.

[0047] As shown in Figure 4(A), the width W4 between arm 72A and engagement portion 14 of crop management device 10 is set to, for example, 15 mm. Furthermore, the vertical distance (height H3) between tip 74A of arm 72A and engagement portion 14 of crop management device 10 is set to, for example, approximately 8 mm. The same is true for the other arm 72B. As shown in Figure 4(B), tip 74A of arm 72 is provided with a curved cover relief portion 75 for allowing the cover (engagement portion 14) to escape.

[0048] <Structure and Operation of the Urging Mechanism> Next, the urging mechanism 70A of the arm 72A will be described. As shown enlarged in Fig. 3(B), the urging mechanism 70A includes a spring 90A as urging means, and one end 92A drawn out from the wound portion of the spring is fixed by passing through a through-hole 65 provided below the side surface 60B of the cover body 60, and the other end 92B is hooked onto a hook 78A formed on the upper end 77A of the arm 72A and fixed, as shown in Fig. 4(A).

[0049] A washer 86A is placed on the outside of the arm 72A, and a shank 84B of a bolt 80A is fixed so that it passes through openings 78A, 88A. The head 82A of the bolt 80A engages with the edge of opening 88A of the washer 86A. The other end of the shank 84B passes through opening 64 in the side surface 60B of the cover body 60 and opening 68 of a washer 66 provided on the inside of the cover body 60, and is fixed with a nut 69. The portion where the nut 69 comes into contact with the main body 52 is reinforced by providing a round pipe 56 on the inside.

[0050] The other biasing mechanism 70B has basically the same configuration, but the winding direction of the spring 90B is opposite to that of the spring 90A.

[0051] Figure 5 shows the range of motion of arm 72A. As shown in the figure, for example, the initial deflection angle α1 of spring 90A is 41°, the service limit angle α2 is 116°, and the no-load angle α3 is 135°. Furthermore, the height H4 of the tip of arm 72A in the no-load state is set to, for example, 8.13 mm. Furthermore, the protrusion amount (height H5) of arm 72A in the no-load state and the service limit state is set to, for example, 18.7 mm. The same applies to the other arm 72B.

[0052] Figure 6 shows how the first wire 102A is raised and lowered by the wire lifting device 50 of this embodiment. In the state shown in Figure 6(A), the crop management device 10 has not yet approached, and the first wire 102A is being lifted upward by the biasing force of the springs 90A and 90B provided on the arms 72A and 72B (unloaded state). At this time, the first wire 102A is being pressed down from above by the receiving portions 76A and 76B at the tips of the arms 72A and 72B.

[0053] Next, as the crop management device 10 gradually approaches, a load is applied by the weight of the crop management device 10, causing the springs 90A and 90B to begin to compress. As shown by the arrows in FIG. 6(B), the pair of arms 72A and 72B gradually descend, and the supports 76A and 76B begin to press down on the first wire 102A. Furthermore, when the crop management device 10 approaches completely, the springs 90A and 90B are subjected to a maximum load, causing the arms 72A and 72B to descend completely, as shown by the arrows in FIG. 6(C). At this time, the receiving portions 76A and 76B of the tips 74A and 74B of the arms 72A and 72B receive the underside of the first wire 102A. In this state, the crop management device 10 passes under the wire lifting device 50, as shown in FIG. 2(B).

[0054] The operation of this embodiment is shown in Figure 7. In Figure 7(A), the crop management device 10 approaches the wire lifting device 50 sufficiently, and its own weight lowers the pair of arms 72A and 72B against the biasing force of the springs 90A and 90B. The first wire 102A is also in its lowered position. Next, as shown in Figure 7(B), the engagement portion 14 of the crop management device 10 passes over the first wire 102A held by the lowered pair of arms 72A and 72B. When the crop management device 10 passes completely under the wire lifting device 50, the biasing force of the springs 90A and 90B raises the pair of arms 72A and 72B in the direction indicated by the arrows in Figure 7(C), and the first wire 102A held by these arms 72A and 72B also rises. The fully raised state is shown in Figure 6(A).

[0055] 7 and 8, the wire suspension device 50 may be fixed by a square beam 120 instead of the second wire 102B. In this case, the frame 60 of the wire suspension device 50 does not need to have a predetermined length in the extension direction of the second wire 102B for fixing, as is the case with the second wire 102B, and the frame 60 can be fixed compactly by fitting the inverted recess into the protrusion of the square beam 120 from above. In addition, when the arms 72A, B of the wire suspension device 50 are in the raised position, the arms 72A, B are stored in the height direction of the beam 120, and when stored, the arms 72A, B do not protrude to the top or bottom, and the first wire 102A is fixed to the bottom surface of the beam 120.

[0056] <Effects> As described above, the wire lifting device 50 of this embodiment lifts up the first wire 102A when the hanging-type crop management device 10 that moves along the first wire 102A is not moving or when the crop management device 10 is not in a harvesting position, thereby preventing it from interfering with agricultural work, and a crop management system 100 that utilizes the same can be provided.

[0057] Although preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. The configuration of the crop management device 10 shown in the above embodiments is merely an example, and any structure that allows the first wire 102A to pass through may be used. Furthermore, the shape of the wire lifting device 50 shown in the above embodiments is also merely an example, and the design may be modified as appropriate to achieve similar effects. For example, in the above embodiments, the first wire 102A is held by the receiving portions 76A, 76B provided on the tips 74A, 74B of the pair of arms 72A, 72B. However, this is also merely an example, and appropriate design modifications are possible within the scope of achieving similar effects, such as using hooks instead of the receiving portions 76A, 76B.
