[Industrial applications]

 The present invention relates to a fruit sorter. For more details, in the case of dividing roughly spherical fruits and vegetables such as mandarin oranges, persimmons, chestnuts, plums and onions, or roughly elliptical fruits and vegetables such as cucumbers, sweet potatoes and potatoes according to their size. Regarding the fruit sorter used for.

[0002]

[Prior art]

 Conventionally, there is, for example, the one shown in FIG. 12 as a fruit sorter 100 for classifying mandarin oranges and plums according to their dimensions. This fruit sorter 100 is divided into a loading platform 101 on which a mandarin orange 107 to be sorted is placed, rolls 102 and 103 for sorting the mandarin orange 10 7 according to its size, and a roll support platform 104 supporting the rolls 102 and 103. It is composed of pedestals 105 and 106 for guiding the mandarin orange 107 to a storage box or the like (not shown). The loading table 101 is formed to have a width substantially equal to the width of the roll supporting table 104 in the vicinity of a connecting portion with the roll supporting table 104 so that the mandarin orange 107 can be smoothly moved to the rolls 102 and 103 side. Further, the height of the surface of the loading platform 101 is set higher than that of the roll support platform 104 so that the mandarin orange 107 can be easily sent to the rolls 102 and 103 side.

Each of the rolls 102 and 103 has a large number of circular holes around the rolls 102 and 103 corresponding to the size to be divided, and the diameters of the circular holes around the rolls 102 and 103 are set apart from the loading platform 101 (the mandarin orange It is formed so that it becomes larger sequentially (along the moving direction). Then, the rolls 102 and 103 are attached to the roll support base 104 so as to be swingable.

The roll support base 104 is configured to be inclined downward toward the front so that the can 107 of the loading base 101 can be easily moved forward. The cradle 105, 106 is installed inside the rolls 102, 103 so that the mandarin oranges 107 divided by the rolls 102, 103 can be reliably guided to the storage box or the like, and one end thereof is guided to the storage box or the like. In this conventional example, two rolls are provided, but the number of rolls can be increased or decreased as necessary, and the configuration is almost the same as the case of two rolls.

The operation of sorting the mandarin oranges 107 by the fruit sorter 100 according to their dimensions is performed as follows. First, the box or the like containing the oranges 107 to be sorted is lifted and the oranges 107 are loaded into the loading platform 101. Next, the mandarin orange 107 is manually stirred in the loading table 101 to inspect for scratches, the mandarin orange 107 is removed, and at the same time the mandarin orange 107 is lightly pushed forward (on the rolls 102, 103 side) by hand. Then, due to the inclination of the roll support base 104, the mandarin orange 107 moves while rolling forward, and the mandarin orange 107 that is smaller than the diameter of the circular hole formed around the roll 102 when passing over the roll 102 is surrounded by the roll 102. It falls down from the circular hole formed in and is collected in a storage box or the like by the receiving stand 105. The mandarin orange 107 larger than the diameter of the circular hole formed around the roll 102 moves further forward, and when passing over the roll 103, the mandarin orange smaller than the diameter of the circular hole formed around the roll 103 is formed. It falls down from a circular hole formed around the roll 103, and is collected by a receiving stand 106 in a storage box or the like. The mandarin orange 107, which is larger than the diameter of the circular hole formed around the roll 103, moves further forward and reaches the tip 104a of the roll support base 104, so that it is stored below the tip 104a. If a box or the like is installed, mandarin oranges 107 larger than the diameter of the circular hole formed around the roll 103 can be gathered together in a storage box or the like.

In the conventional example, the rolls 102 and 103 are set in a swingable state, and the rolls 102 and 103 are rotated by the mandarin orange 107 that has moved forward due to the inclination of the roll support base 104, and the mandarin oranges 107 are sequentially rotated. Although the method of dividing is adopted, a method of previously rotating the rolls 10 2 and 103 at a constant speed by a motor or the like is also considered. The above work has been described for mandarin oranges, but it is possible to classify fruits and vegetables of roughly spherical shape by similar work.

[0007]

[Problems to be solved by the device]

 However, the conventional fruit sorter 100 has the following problems. The height of the surface of the loading platform 101 is set higher than the height of the roll support platform 104 so that the mandarin orange 107 can be easily sent to the rolls 102 and 103 side. Therefore, in order to put the mandarin orange 107 into the loading platform 101, a box or basket containing the mandarin orange 107 must be lifted up to the height of the loading platform 101, which requires a plurality of manpower. In order to inspect the mandarin oranges 107 for scratches, a large number of mandarin oranges 10 7 should be thoroughly agitated in the loading table 101 by hand, and a large number of mandarin oranges 107 should be inspected within a short period of time to remove the damaged mandarin oranges 107. Requires multiple hands because it must be done. If the shape of the mandarin orange 107 is not spherical, it may not fall from the circular hole to be divided formed around the roll but may fall from the large diameter circular hole formed around the next roll. It is difficult to make a distinction. Since circular holes are formed around the roll, it is not possible to divide potatoes that are not spherical in shape.

In view of such circumstances, the present invention can reduce the number of manpower without having to lift the box or basket containing the mandarin oranges to be sorted to the height of the loading platform, and to easily check whether the mandarin oranges are scratched or not. It can be reliably inspected to improve work efficiency, and it can be accurately divided and can be used even when the shape of fruits to be divided is not spherical. The purpose is to provide a fruit sorter.

[0009]

[Means for Solving the Problems]

 The fruit sorter of the present invention is a fruit sorter equipped with a loading section, an inspection section, and a sorting section, in which a plurality of moving units are orbitally moved by a chain, and the moving unit comprises two cylindrical bodies. Are connected to each other at their both ends so as to be rotatable and parallel to each other, and one cylinder is pivotally supported by the chain and the other cylinder is swingable with respect to one cylinder. The loading section is composed of a plurality of moving units and inclined upper and lower guide members for guiding the moving units, and the inspecting section is for guiding the plurality of moving units and the moving units. The moving section is composed of a plurality of moving units, and an upper guide member and a step-like guide member which are within the moving units, and the swingable cylindrical body is a step-like guide. Distance between the mobile units each other, characterized in that the increased sequentially by descending the stairs of wood.

[0010]

[Action]

 In the fruit sorter of the present invention, since the fruits and the like can be moved upward in the lifting portion, the loading platform installed at the lower end of the rear surface portion of the body of the fruit sorter (opposite to the traveling direction of the fruits and the like). Since it is only necessary to put fruits and the like inside, it is not necessary to lift the box or basket containing the fruits and the like to be sorted to the height of the inspection department, so the number of workers can be reduced. In addition, since the fruits etc. that have moved from the unloading section move while rotating in the inspection section, it is possible to inspect the presence of scratches without having to stir the fruits one by one. Since fruits such as scratches can be reliably removed, the number of workers can be reduced and the work efficiency can be improved. Furthermore, as a means for separating fruits and the like in the sorting section, the intervals between the mobile units are used, and the intervals between the mobile units are rectangular gaps, and the intervals gradually increase along the traveling direction of the fruits and the like. Therefore, even if the shape of the fruit or the like is not a perfect spherical shape, accurate classification can be performed, so that the accuracy of classification can be improved. Further, since the shape can be divided even if the shape is not a sphere but an ellipse, it can be used for multipurpose division.

[0011]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a fruit sorter A which is an embodiment of the present invention. In this fruit sorter A, a plurality of moving units 1 are orbitally moved by a chain 7 (see FIG. 4), and the lower end of the rear surface of the main body of the fruit sorter A (on the side opposite to the traveling direction of fruits, etc.). A loading platform 9 is installed in the section. Further, it is roughly composed of a loading section 2, an inspection section 3 and a sorting section 4.

As shown in FIG. 1, the loading platform 9 has its front end connected to the lower end of the rear surface of the main body of the fruit sorter A, and together with the lower end forms a box for storing fruits and the like. Further, a notch 25 is formed at the lower end of the rear part of the main body of the fruit sorter A, and fruits or the like placed in the loading platform 9 are loaded from the notch 25 between the front and rear moving units 1 in the lifting section 2. It will be moved to the storage space. The rear end of the loading platform 9 is set higher than the front end thereof in order to smoothly move the fruits and the like to the space, and the box body faces the lower end of the rear surface of the fruit sorter A main body. It is configured to be inclined.

As shown in FIG. 2, the moving unit 1 is configured by connecting two columnar bodies 11 and 12 having substantially the same length so as to be axially rotatable and parallel to each other at both ends thereof. That is, the central axes 13 and 14 are formed on the cylindrical bodies 11 and 12, respectively, and one central axis 13 is slightly projected from both ends of the cylindrical body 11, and the other central axis 14 is considerably protruded from both ends of the cylindrical body 12. Let it project. Then, a flange 15 for preventing the fall of fruits and the like is fitted into the central shafts 13 and 14, and two cylindrical bodies 11 and 12 are connected to each other by a locking metal fitting 16. Further, a guide roll 17 is fixed slightly inward of the tip end portion of the central shaft 14 to integrally form the central shaft 14 and the guide roll 17. The diameter of the guide roll 17 is substantially the same as the diameter of the cylindrical body 12, and a plurality of shallow grooves for preventing slippage are formed on the surface of the guide roll 17 in the axial direction.

One columnar body 12 of the moving unit 1 is pivotally supported by the chain 7, and the other columnar body 11 is swingable with respect to the one columnar body 12. That is, as shown in FIG. 3, both ends of the center shaft 14 are fitted into and supported by small holes 75 (see FIG. 4) formed in the chain 7, and the cylindrical body 11 can swing with respect to the central shaft 14. Has become. The guide roll 17 integrally formed with the central shaft 14 is guided by the upper guide member 31, and the cylindrical body 11 swingable with respect to the central shaft 14 is guided by the lower guide member 32. In this embodiment, synthetic resin is used as the material for the cylinders 11 and 12, but any material such as wood may be used as long as the cross section is circular. Also, in consideration of weight reduction and economy, it is possible to use hollow cylinders with both ends closed instead of the cylinders 11 and 12.

As shown in FIG. 4, the chain 7 is attached to the sprockets 71, 72, 73, 74 so as to incline in the loading section 2 and to be in a horizontal state in the inspection section 3 and the selection section 4. There is. Then, the sprocket 71 is driven by the motor 76 (see FIG. 1), and the chain 7 continuously moves in a trapezoidal shape. In this embodiment, the sprockets 72, 73, 74 are of the same shape and size, and the sprocket 71 is larger than the sprockets 72, 73, 74. An appropriate size can be used depending on the size of A.

As shown in FIG. 5, the unloading section 2 is composed of a plurality of moving units 1 and an upper guide member 21 and a lower guide member 22 which are inclined to accommodate the moving units 1. The upper guide member 21 and the lower guide member 22 are made of a plate material such as an iron plate, and are made by sticking rubber to the surface of the plate material to prevent the moving unit 1 from slipping. There is no need to attach rubber. The upper guide member 21 and the lower guide member 22 are arranged below the chain 7 and in parallel with the chain 7, and are inclined with respect to the horizontal plane at the same inclination angle as the chain 7. The front and rear moving units 1 form a placing space for placing fruits and the like between the moving units 1. The size of the placing space is determined by the lower guide member 22 on the outer frame of the fruit sorter A. The length can be adjusted by appropriately adjusting the length of the mounting member to which is attached and moving the lower guide member 22 in parallel.

As shown in FIG. 5, the inspection unit 3 is composed of a plurality of moving units 1 and an upper guide member 31 and a lower guide member 32 which are included in the moving units 1. The upper guide member 31 and the lower guide member 32 are formed of a plate material such as an iron plate, and in order to surely rotate the cylindrical bodies 11 and 12 of the moving unit 1, those having rubber attached to the surface thereof are used. . The upper guide member 31 and the lower guide member 32 are arranged below the chain 7 and in parallel with the chain 7. In this embodiment, the upper guide member 31 is the upper guide member of the unloading section 2. The lower guide member 32 and the lower guide member 32 are connected to the lower guide member 22 of the unloading unit 2, respectively. However, if the moving unit 1 can smoothly move from the unloading unit 2 to the inspection unit 3, they are not necessarily connected. do not have to. The front and rear moving units 1 form a mounting space between the moving units 1 for mounting fruits and the like.

As shown in FIG. 5, the sorting unit 4 is composed of a plurality of moving units 1 and an upper guide member 41 and a step-like guide member 42 that incorporate the moving units 1. The upper guide member 41 is formed of a plate material such as an iron plate, and is made by attaching rubber to the surface of the plate material in order to prevent the movement unit 1 from slipping, but it is not always necessary to attach rubber to the surface of the plate material. . The upper guide member 41 is connected to the upper guide member 31 of the inspection unit 3 so that the moving unit 1 can smoothly move from the inspection unit 3 to the sorting unit 4. On the other hand, as the step-shaped guide member 42, in the present embodiment, a plate material such as an iron plate to which a rubber formed in a step shape is attached is used. It may be one. Note that it is not always necessary to attach rubber to the surface of the step-shaped guide member 42, but since the moving unit 1 descends the stairs of the step-shaped guide member 42 in sequence on the surface of the step-shaped guide member 42. In order to prevent the damage of No. 1, it is preferable to attach rubber to the surface of the step-shaped guide member 42. The swingable columnar body 11 descends the stairs of the staircase guide member 42 so that the distance between the front and rear moving units 1 is gradually increased. The distance between the front and rear moving units 1 is set so that the length of the mounting member that attaches the stepwise guide member 42 to the outer frame of the fruit sorter A is appropriately adjusted to move the stepwise guide member 42 in parallel. Can be adjusted. The distance between the front and rear moving units 1 can also be adjusted by changing the height of the steps of the step-shaped guide member 42.

As shown in FIG. 5, the front surface portion 5 of the main body of the fruit sorter A (the direction in which fruits and the like travel) has the columnar bodies 11 and 12 of the moving unit 1 that have passed through the sorting unit 4 arranged in a line in order. The inner guide member 51 and the outer guide member 52 are arranged on both sides of the passage of the moving unit 1 and at positions corresponding to substantially both ends of the cylindrical bodies 11 and 12 so as to descend toward the bottom surface portion 6. . The inner and outer guide members 51, 52 are made of a plate material such as an iron plate, and the inner guide member 51 smoothly passes through the stepped guide member 42 of the sorting section 4 so that the cylindrical body 11 of the moving unit 1 can be smoothly moved. The front end is curved so that it can be moved to the front face 5, and the front end is in contact with the end of the step-shaped guide member 42.

As shown in FIG. 5, the bottom surface portion is provided with a bottom surface portion guide member 61 so that the cylindrical bodies 11 and 12 of the moving unit 1 can move on substantially the same horizontal plane. The bottom surface guide member 61 is formed of a plate material such as an iron plate. A plurality of pedestals 43 each having a groove formed by bending a synthetic resin are arranged in parallel below the sorting unit 4, and the fruits or the like which are sorted by the sorting unit 4 by the receiving unit 43 and fall into a storage box or the like. It will be stored.

Next, the operation of selecting, for example, mandarin oranges 8 according to the size (dimension) using the fruit sorter A of this embodiment will be described. First, the motor 76 is driven to rotate the sprocket 71 and move the chain 7 in an orbit, so that the moving unit 1 orbits from the load raising unit 2 to the inspection unit 3, the sorting unit 4, the front face unit 5, and the bottom face unit 6. It is in a state of doing.

When the mandarin orange 8 is inserted into the box body of the loading platform 9 in this state, the mandarin orange 8 is lifted from the notch 25 formed in the lower end portion of the rear surface of the fruit sorter A main body due to the inclination of the box body. It moves to the loading space 23 between the front and rear moving units 1 in the loading section 2, and the mandarin oranges 8 are sequentially loaded in the loading space 23 and moved to the upper part of the lifting section 2 as shown in FIG. Go. At this time, if the mandarin orange 8 is too large to be placed in the placing space 23, as shown in FIG. 7, the lower guide member 22 is attached to the outer frame of the fruit sorter A as shown in FIG. By moving the lower guide member 22 in parallel downward to make the distance L2 between the chain 7 and the lower guide member 22 larger than the distance L1 shown in FIG. Since 23 can be taken large, a large mandarin orange 8 can be placed in the placing space 23. If the size of the mandarin orange 8 is small, the mandarin orange 8 falls downward from the space between the moving units 1. In such a case, the lower guide member 22 is moved in parallel in the opposite direction to the front and rear moving units. It suffices to make the mounting space 23 between 1 smaller.

Next, the mandarin orange 8 that has moved up in the unloading unit 2 moves to the inspection unit 3. In the inspection unit 3, as shown in FIG. 8, the mandarin orange 8 is placed in the placing space 33 between the front and rear moving units 1 and the moving unit 1 is moved forward (to the right in FIG. 8). However, since the guide roll 17 of the moving unit 1 is rotating due to the friction with the rubber attached to the upper guide member 31 in this state, the cylindrical body 12 is rotating, and the cylindrical body 11 is also rotating. It rotates due to friction with the rubber attached to the lower guide member 32. Therefore, the mandarin orange 8 placed in the above-mentioned mounting space 33 comes into contact with the cylindrical body 11 and the cylindrical body 12 of the front and rear moving units 1, so that the mandarin orange 8 moves while rotating in the inspection unit 3. It is in the state of doing. Therefore, when one person stands beside the inspection unit 3 and finds a damaged mandarin orange 8, it can be removed. Therefore, the mandarin orange 8 can be easily and reliably removed. it can.

When the mandarin oranges 8 that have been inspected by the inspection unit 3 (that is, are not scratches) move to the selection unit 4, selection according to the size of the mandarin oranges 8 is performed as follows. First, as shown in FIG. 9, since the guide roll 17 of the moving unit 1 moves in contact with the upper guide member 41, the columnar body 12 moves on substantially the same plane as the upper guide member 41. The columnar body 11 comes into contact with the step guide member 42 and moves. Therefore, the distance between the front and rear moving units 1 gradually increases along the moving direction of the moving unit 1 by a length corresponding to the height of the stairs of the stepwise guide member 42. That is, in the state of FIG. 9, the distance between the front and rear mobile units 1 is L11 <L12 <L13 <L14 <L15, L12-L11 = L13-L12 = L14-L13 = L15-L14, and the difference is It corresponds to the difference in height of the stairs. In this case, the size of L11 is determined by the difference between the upper guide member 31 of the inspection unit 3 and the height of the uppermost step of the step guide member 42 of the sorting unit 4.

Therefore, the mandarin orange 8 having a size smaller than the interval L11 is dropped at the interval L11 and is stored in the storage box or the like through the receiving table 43. Next, the orange 8 having a size larger than the interval L11 and smaller than L12 drops at L12, passes through the receiving base 43, and is stored in a storage box or the like. Thereafter, the oranges 8 having a size smaller than L13, L14, and L15 are sequentially stored in a storage box or the like through the receiving base 43. Finally, the mandarin orange 8 having a size larger than L15 falls outside from the sieving plate 44 (see FIG. 1) installed at the end of the sorting unit 4, so that a pedestal (not shown) is provided on the front of the fruit sorter A. By installing, it is possible to store the orange 8 having a size larger than L 15.

When the mandarin oranges 8 to be sorted are large as a whole, the step-like guide member 42 is translated downward to increase the distance between the upper guide member 41 and the step-like guide member 42 as shown in FIG. By doing so, the distance between the mobile units 1 can be increased. Also in this case, the size of L21 is determined by the difference between the upper guide member 31 of the inspection unit 3 and the height of the uppermost staircase of the step-shaped guide member 42 of the sorting unit 4. The distance between the front and rear moving units 1 is L21 <L22 <L23 <L24 <L25, and L22-L21 = L23-L22 = L24-L23 = L25-L24, which corresponds to the difference in stair height. is doing. Therefore, since the step-shaped guide members 42 in FIGS. 9 and 10 have the same shape and the same size, L12-L11 = L13-L12 = L14-L13 = L15-L14 = L22-L21 = L23-L22 = L24- L23 = L25-L24. Therefore, regardless of the size of the mandarin orange 8, it is possible to perform sorting with the same dimensional difference.

Further, when selecting with a large dimensional difference, the height of the stairs of the stepwise guide member 42 may be increased as shown in FIG. That is, in the case of FIG. 11, as in the case of FIG. 9, the difference between the upper guide member 31 of the inspection unit 3 and the height of the uppermost staircase of the stepwise guide member 42 of the sorting unit 4 is the same, so L11 = L31. However, since the height of the stairs of the stepwise guide member 42 in the case of FIG. 11 is larger than that in the case of FIG. 9, L12 <L32, L13 <L33, L14 <L34, L15 <L35. ing. Therefore, it is possible to sort with a large dimensional difference. On the other hand, when performing sorting with a small dimensional difference, the height of the steps of the step-shaped guide member 42 may be reduced, contrary to the above. In addition, in FIG. 11, the stepwise guide member 42 is horizontally moved downward to increase the distance between the upper guide member 41 and the stepwise guide member 42, and the locking metal fitting 16 of the moving unit 1 should be replaced with a longer one. It is also possible to carry out sorting with a large dimensional difference.

Further, if the shape is not spherical like mandarin orange but oval like potato, it is placed in the placing space between the front and rear moving units 1 in a direction substantially perpendicular to the axial direction of the moving unit 1. However, as the moving unit 1 moves forward, the potato gradually changes its direction so as to be in a more stable state, that is, substantially parallel to the axial direction of the moving unit 1, and thus moves to the sorting unit 4. When you do, all potatoes are almost parallel to the axial direction of the mobile unit 1. Therefore, it is possible to sort according to the interval between the front and rear moving units 1.

As described above, in the fruit sorter A according to the present embodiment, the mandarin orange 8 is simply moved into the loading table 9 and the mandarin orange 8 is moved up to the loading section 2 and moved to the upper inspection section 3. Since the mandarin orange 8 rotates in the inspection unit 3, the mandarin orange 8 can be easily inspected, and the scar 8 can be easily and surely removed, resulting in a significant improvement in work efficiency. Can be achieved. Further, since the sorting section 4 uses the rectangular gap between the front and rear moving units 1 to perform sorting, the mandarin orange 8 can be reliably sorted, and even if it has an elliptical shape, sorting is possible. Expands applications. Further, in the sorting unit 4, vibrations when the moving unit 1 descends the stairs of the step-shaped guide member 42 can surely sort even the oranges 8 having substantially the same size as the interval between the moving units 1. The accuracy of is increased. Although the five-step sorting is adopted in this embodiment, the sorting classification can be changed appropriately.

[Effect of device]

 According to the present invention, when a fruit or the like is put into the loading table, the fruit or the like moves upward in the loading section and moves forward while rotating in the inspection section. Since it is only necessary to inspect for the presence and absence of these, it is possible to reduce the number of workers and improve the work efficiency. In addition, in the sorting section, the distance between the mobile units is a rectangular gap, and since they are gradually increasing along the direction of travel of the fruit, etc., the shape of the fruit, etc. may not be a perfect spherical shape. Since accurate classification can be performed, the accuracy of classification can be improved. Further, even if the shape of a fruit or the like is not spherical but elliptical, etc., it can be classified, so that it can be used for versatile classification.
