Description

[Technical Field]

[0001] The present invention relates to a method and device for cutting and removing (cutting off) unnecessary parts of agricultural products, such as the tip roots (fine roots) of sweet potatoes and the remaining parts of vines (stems) (base roots, neck roots). [Background technology]

[0002] As shown in Figure 1(a), sweet potato A has an apical root (fine root) B and a base root (neck root) C on the opposite side (the side where the vine is cut). Before shipping, harvested sweet potato A has its apical root B and base root C cut off. Normally, rather than just cutting off the tips of the apical root B and base root C, the cuts are made at the cutting points EE and FF in Figure 1(a), and the tips (unnecessary parts) from the apical root B and base root C are removed. In this case, some of the flesh D of sweet potato A is also cut off. The positions of the cutting points EE and FF are set so that the cross-sectional area of ​​the cuts G and H (Figure 1(b)) is at most about the size of a one-yen coin.

[0003] Conventionally, there is a device disclosed in Patent Document 1 for cutting off the roots of sweet potatoes. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-141619 Summary of the Invention [Problem to be solved by the invention]

[0005] Because each crop is different in shape and size, it is difficult to identify the location of the unnecessary parts to be cut off. As a result, there is a risk of cutting off too much or leaving some parts uncut.

[0006] The problem to be solved by the present invention is to provide a method and an apparatus that can cut off (remove) unnecessary parts of agricultural products without cutting too much or leaving too much. [Means for solving the problem]

[0007] [Method for removing unnecessary parts of agricultural crops] The method of cutting out unnecessary parts of agricultural produce of the present invention involves loading each agricultural produce onto a receiving device and transporting it, determining the cutting point of the agricultural produce during transport using a determination device, selecting a cutting blade to be lowered from two or more cutting blades positioned above the agricultural produce being transported, lowering the selected cutting blade toward the agricultural produce being transported and bringing it into contact with the determined cutting point, and cutting out the unnecessary parts of the agricultural produce from the cutting point.

[0008] [Device for removing unnecessary parts of agricultural crops] The device for cutting out unnecessary parts of agricultural produce of the present invention comprises a conveying device having a running body such as a chain or belt on which a number of receiving devices on which agricultural produce can be placed, a judgment device for judging the cutting points of the agricultural produce placed on the receiving devices while being transported, and a device for selecting a cutting blade to be lowered from two or more cutting blades positioned above the agricultural produce being transported based on a signal from the judgment device, and lowering the selected cutting blade so that it abuts against the cutting point, thereby cutting out the unnecessary parts of the agricultural produce from the cutting point. [Effects of the Invention]

[0009] [Method for removing unnecessary parts of agricultural crops] The cutting position is determined while the agricultural product is being transported, and the cutting blade is lowered to correspond to the determined cutting position and cut from the cutting position, so that unnecessary parts can be cut off without excess or deficiency.

[0010] [Device for removing unnecessary parts of agricultural crops] The cutting portion of the agricultural product being placed on a receiving tool and transported can be determined by a determination device, a cutting blade can be selected based on a determination signal from the determination device, and the cutting blade can be used to cut from the determined cutting portion, so that unnecessary portions can be cut off just enough while the agricultural product is being transported.

DETAILED DESCRIPTION OF THE INVENTION

[0012] The method and device for cutting away unwanted parts from agricultural produce of the present invention will be described below with reference to the drawings, using a sweet potato as an example of the agricultural produce. The following embodiment also applies to cutting so that the cross-sectional area of ​​the cut edges G and H (Figure 1(b)) is at most the size of a one-yen coin.

[0013] (Embodiment of Method for Removing Unwanted Parts of Crop) [Determining cut points] In embodiment 1 of the method for removing unnecessary parts of agricultural products, as shown in Figure 2, sweet potatoes A are loaded one by one onto a receiving tool 1 moving in the direction of arrow X and transported, and the cutting points EE and FF (Figure 1(a)) of the sweet potatoes A as they are transported are determined by a determination device (not shown). The determination device photographs the sweet potatoes A with a photographing device (not shown) and determines the cutting points EE and FF based on the photographed image. Based on a determination signal from the determination device, a cutting blade to be lowered is selected from two or more cutting blades 2 arranged above the transport device, and that cutting blade is lowered and pressed against the cutting points EE and FF to remove the tip root B from the cutting point EE and the base root C from the cutting point FF.

[0014] It is desirable that the cutting points EE and FF be positioned so that the cross-sectional area of ​​the cut G at the tip root B of the sweet potato A and the cut H at the base root C is at most about the size of a one-yen coin.

[0015] [Cutting with a cutting blade] Cutting is performed with a cutting blade 2. In this case, as shown in Figure 2, from two or more cutting blades 2 arranged above the sweet potato A being transported in the longitudinal direction of the sweet potato A, the cutting blade 2 arranged at the position corresponding to (including the vicinity of) the cutting points EE and FF is selected based on a determination signal from the determination device, and is lowered and pressed against the cutting points EE and FF to cut the sweet potato A on the receiving tool 1.

[0016] The excision of the distal root B from the cut point EE and the excision of the proximal root C from the cut point FF can be performed simultaneously or at different times. It is also possible to excise only one of the roots.

[0017] [Pressing tool] When cutting the tip root B and base root C with the cutting blade 2, if the sweet potato A shifts sideways, the cutting point may shift. Therefore, as shown in Figure 6, it is desirable to press the sweet potato A against the receiving device 1 with a pressing device (e.g., a belt) 3 to prevent the sweet potato A from accidentally shifting position. The pressing device 3 is an endless belt and is rotatable. When the pressing device 3 is rotated in the opposite direction to the movement of the receiving device 1, the sweet potato A placed on the receiving device 1 becomes stable.

[0018] [Equal class discrimination] The judging device can not only judge the cut points EE and FF, but also determine the grade of sweet potato A. Grade determination is performed as grade A, grade B, etc. based on the shape, size, color, and other conditions of the photographed sweet potato A.

[0019] [Sweet potato discharge] The sweet potatoes A, from which the tip roots B and base roots C have been removed, can be sent out from the receiver 1 to a discharge conveyor (not shown). In this case, discharge conveyors for grades such as A grade, B grade, ..., and N grade can be placed next to the conveying device 5, and the sweet potatoes can be sent out to the discharge conveyor for the grade that corresponds to the grade determined by the judging device.

[0020] (Embodiment 1 of the crop cutting device) [Transportation equipment] As shown in Figure 2, the agricultural product cutting device of the present invention is equipped with a conveying device 5 (Figures 2 and 3) in which a number of receiving devices 1 for carrying and transporting sweet potatoes A one by one are attached at regular intervals to an endless rotating running body 4 such as a chain or belt (hereinafter referred to as the "running body"), a pressing device 3 (Figure 6) for pressing the sweet potatoes A placed on the receiving device 1 to prevent them from shifting position, a judgment device for judging the cutting points EE and FF of the sweet potatoes A during transport, a lifting device 9 that rises and falls based on a signal from the judgment device, and a cutting blade 2 that rises and falls in conjunction with the lifting device 9 to cut off the unnecessary parts of the sweet potatoes A.

[0021] [Bracket] As shown in Figure 5(a), the receiving device 1 has several support pieces 7 protruding at intervals from a horizontally long substrate 6. The substrate 6 is a thick plate. The support pieces 7 are thinner plates than the substrate 6, protrude above the substrate 6, and are arranged in a row at predetermined intervals in the horizontal direction of the substrate 6. The two central support pieces 7 have a positioning portion 8 in the center of their upper surfaces, which is V-shaped or U-shaped as shown in Figure 6. A sweet potato A is placed horizontally on the positioning portion 8 so that the sweet potato A can be positioned. The positioning portion 8 may also be a recess of another shape, such as an arc-shaped or rectangular recess.

[0022] The multiple support pieces 7 (Fig. 5(a)) arranged in a horizontal row are the same height, but as shown in Fig. 5(b), the height of the outer support pieces 7 can also be made shorter than the height of the inner support pieces 7. By making them shorter, the cutting blade 2 that descends when cutting the tip root B and base root C is less likely to come into contact with the outer support pieces 7, making it less likely that the cutting edge of the cutting blade 2 will be damaged.

[0023] [Judgment device] The judgment device includes a photographing device that photographs the sweet potato A during transportation, a judgment unit (e.g., a CPU: central processing unit) that judges the cut points EE and FF of the sweet potato A based on the image photographed by the photographing device, and a transmission function that transmits the judged cut points EE and FF as judgment signals to the cutting blade 2. The photographing device can be, for example, a camera (not shown) that can take still images or video.

[0024] It is desirable that the judging device not only judges the cut points EE and FF, but also has a grade discrimination function that can distinguish the grade of sweet potato A. Grade discrimination can be performed based on the shape, size, color, etc. of sweet potato A using images taken by the photographing device, such as grade A, grade B, etc.

[0025] [Lifting device] A number of lifting tools 9 (Figure 2) are arranged in a row above the conveying device 5 at intervals in the horizontal direction (longitudinal direction of the sweet potatoes A), and are selected and lowered based on a judgment signal from the judgment device.

[0026] As shown in Figures 2 and 4, each lifting tool 9 comprises an extendable tool 11, a front-rear moving arm 12, and a blade mounting arm 13. The extendable tool 11 is a cylinder type in which a rod 14 can be extended and retracted in the vertical direction. The upper end of the extendable tool 11 is suspended from a first support rope 15 (Figure 2). The front-rear moving arm 12 and the blade mounting arm 13 are rotatably connected to the lower end of the rod 14 by a first connecting shaft 10 (Figure 2). The front-rear moving arm 12 is supported by a second support rope 17 (Figure 2).

[0027] As shown in Figures 2 and 3, the multiple lifting tools 9 are arranged on the left and right sides of the sweet potato A placed on the receiving tool 1 in the longitudinal direction.

[0028] A large number of the lifting tools 9 are arranged in a horizontal row in the running direction of the running body 4 (the direction in which the sweet potatoes are transported), and each lifting tool 9 can be raised and lowered based on a determination signal from a determination device.

[0029] As shown in Figures 2 and 3, two or more sets of lifting tools 9 are arranged in a horizontal row, one before the other in the traveling direction of the traveling body 4. By arranging two or more sets, two or more sets of lifting tools 9 can be raised and lowered simultaneously to remove unnecessary parts of the sweet potato.

[0030] [Cutting blade] The cutting blades 2 are rotatably attached to the tip (lower end) of each of the multiple lifting tools 9 (Fig. 2) by a second connecting shaft 16 (Fig. 4), and are lowered as the lifting tools 9 descend, and pressed against the tip B and base C of the sweet potato A, rotating as the sweet potato A is transported, so that they can cut the tip B and base C (Fig. 1(a)) from cutting points EE, FF. After cutting, the cutting blades 2 rise as the lifting tools 9 rise, and return to their original position.

[0031] [Cutting off the tip and base of the roots with a cutting blade] Of the many lifting tools 9 (Fig. 2) arranged in a horizontal row, one of them is selected to move up and down based on a judgment signal from the judgment device. When the selected lifting tool 9 moves from the state shown in Fig. 8(a) to the state shown in Fig. 8(b), the rod 14 of the telescopic tool 11 extends and the first connecting shaft 10 (Fig. 4) is pushed down, as shown in Fig. 8(c), the forward / backward moving arm 12 and the blade mounting arm 13 descend while tilting forward, as shown in Fig. 8(c), and the cutting blade 2 at the lower end of the blade mounting arm 13 is pressed against the sweet potato A and rotates to cut away unnecessary parts from the cutting points EE and FF, as shown in Fig. 8(d).

[0032] [Returning movement of cutting blade] After the lifting tool 9 has finished cutting the tip root B and the base root C, the rod 14 of the extension tool 11 retracts as shown in Figure 8(e), the downward pressure on the first connecting shaft 10 (Figure 4) is released, the forward / backward moving arm 12 and the blade mounting arm 13 rise backward (return operation), and the cutting blade 2 moves away from the sweet potato A and returns to its original position.

[0033] (Embodiment 2 of the crop unnecessary part removing device) In the crop cutting device of embodiment 2, as shown in Figures 9(a) to (e), a lifting arm 23 and a support arm 24 are rotatably connected to a rod 22 of an extension tool 21 of a lifting tool 9 by a third connecting shaft 25, and a cutting blade 2 is rotatably attached to the lower end of the lifting arm 23 by a fourth connecting shaft 26. The support arm 24 is suspended from a second support cord 17 (Figure 2) as in the case of Figures 8(a) to (e). A large number of lifting tools 9 in Figures 9(a) to (e) are also arranged in a horizontal row above the receiving tool 1 with intervals in the longitudinal direction of the sweet potato A.

[0034] [Cutting off the tip and base of the roots with a cutting blade] For the lifting tools 9 (FIG. 2) shown in FIGS. 9(a)-(e), one of the lifting tools 9 is selected based on a determination signal from the determination device. When the rod 22 of the telescopic tool 21 of the selected lifting tool 9 extends downward, the third connecting shaft 25 is pushed down, and as a result, the lifting arm 23 descends vertically as shown in FIG. 9(c). As the lifting arm 2 descends, the cutting blade 2 is pressed against the cutting point of the sweet potato A as shown in FIG. 9(d), rotating to cut the tip root B and base root C (FIG. 1(a)). The lifting arm 23 also swings in the same direction as the sweet potato A moves during transport, ensuring that unnecessary parts are smoothly removed from the cutting point without applying excessive force to the cutting blade 2. During this process, the lifting arm 23 is supported by the support arm 24.

[0035] [Returning movement of cutting blade] After the lifting tool 9 has finished cutting the tip root B and the base root C, as shown in Figure 9(d), the rod 22 retracts, the third connecting shaft 25 is released from the downward pressure, the lifting arm 23 moves up vertically (returning), and the cutting blade 2 moves away from the sweet potato A and returns to its original position. In this case, the lifting arm 23 is also supported by the support arm 24.

[0036] (Embodiment 3 of the crop unnecessary part removing device) In this embodiment, the lifting tool 9 is an electric cylinder (actuator) as shown in Fig. 10(a). In the electric cylinder of Fig. 10(a), a rod 31 extends and retracts with the rotation of a motor (not shown) inside a cylinder 30. A cutting blade 2 is rotatably attached to the tip (lower end) of the rod 31 by a fifth connecting shaft 32.

[0037] A large number of lifting tools 9 in Figure 10(a) are also arranged in the horizontal direction of the sweet potato A, and the upper ends of the cylinders 30 are supported by cables or other supports (not shown) as in Figure 2. One of the lifting tools 9 is selected based on a determination signal from the determination device, and the selected lifting tool 9 descends to remove unnecessary parts of the sweet potato A.

[0038] In the lifting tool 9 of Figure 10(a), the rod 31 descends before the sweet potato A is transported, and the cutting blade 2 waits on the transport path of the sweet potato A. When the transported sweet potato A hits the cutting blade 2, the unnecessary part of the sweet potato A is cut off. After cutting, the lifting tool 9 rises to its original position.

[0039] (Embodiment 4 of the crop unnecessary part removing device) In this embodiment, the lifting tool 9 is also an electric cylinder (actuator) as shown in Fig. 10(b). In the electric cylinder of Fig. 10(b), a rod 31 extends and retracts with the rotation of a motor (not shown) in a cylinder 30, a movable arm 33 is rotatably connected to the end of the rod 31 by a sixth connecting shaft 34, and a cutting blade 2 is rotatably attached to the tip (lower end) of the movable arm 33 by a seventh connecting shaft 35.

[0040] A large number of lifting tools 9 in Figure 10(b) are also arranged in the horizontal direction of the sweet potato A, and the upper ends of the cylinders 30 are supported by cables or other supports (not shown) as in Figure 2. One of the lifting tools is selected based on a determination signal from the determination device, and the selected lifting tool descends to remove unnecessary parts of the sweet potato A.

[0041] The lifting tool 9 in Figure 10(b) is configured so that when the rod 31 descends, the cutting blade 2 descends onto the conveying path of the sweet potato A and hits the cutting portion of the conveyed sweet potato A to cut off the unnecessary part of the sweet potato A. In this case, when the sweet potato A hits the cutting blade 2, the movable arm 33 swings in the conveying direction of the sweet potato A, causing the cutting blade 2 to cut the cutting portion of the sweet potato A. After cutting, it rises to its original position.

[0042] [Sending sweet potatoes] In any of the first to fourth embodiments, the sweet potatoes A from which the unnecessary parts have been removed can be sent to multiple discharge conveyors (not shown) arranged next to the conveying device (not shown). In this case, the multiple discharge conveyors can be divided into grades such as A grade, B grade, . . ., and N grade, and the sweet potatoes A classified by the classification device can be sent to the discharge conveyor for the grade they are classified into.

[0043] [Recovery Department] In the present invention, a recovery section (not shown) may be provided so that the cut and removed unnecessary parts are recovered in the recovery section. [Industrial Applicability]

[0044] The above-described embodiment is one example of the present invention. The present invention is not limited to this embodiment, and other configurations, structures, and methods can be used as long as the problem of the present invention can be solved. The present invention can also be used to cut the roots of agricultural crops other than sweet potatoes, such as radishes, turnips, scallions, and onions, or to cut unnecessary parts of other agricultural crops. Some of these crops only have the apical root B at the tip of the root vegetable. In this case, it is sufficient to cut only the apical root B. [Explanation of symbols]
