The discrimination area 11 is a place (space) for measuring the shape, size, sugar content, etc. of the fruit vegetable A being carried on the fruit vegetable receiver 8, and the measuring instrument B is arranged therein. The measuring instrument B is arranged above the discrimination area 11 so that the fruit vegetables A being transported can be measured from above. Alternatively, the measuring instrument B is placed beside the discrimination area 11 and the fruit vegetables A being transported from the side. It can be measured, or it can be placed at other positions and measured from different directions. Various types of measuring instruments such as an optical measuring instrument can be used as the measuring instrument B.

(Sorting area)
The sorting area 12 is a place (space) where fruit vegetables A, which are measured by the measuring instrument B in the discrimination area 11 and discriminated in the same class, are sent out to the side of the fruit transport direction, and the fruit vegetables A are sorted (sorted) by class. It is. In this sorting area 12, the sorted fruit vegetables A are sent from the fruit vegetable receptacle 8 to the pool conveyor 3 and sorted. The selected fruit vegetables A can be sent out to a place other than the pool conveyor 3 for sorting.

(Fruit vegetable receptacle)
The fruit vegetable receiving body 8 is a belt conveyor type, and a belt 15 is rotatably wound around the outer periphery of a pair of rotating rollers 14 attached to a frame 13 (FIG. 2) formed of metal, hard resin, FRP or the like. ing. Although the width and length of the belt 15 vary depending on the fruit vegetables A to be placed, a width suitable for placing the fruit vegetables A, for example, about 10 to 15 cm in the case of tomatoes, and about 30 cm in the case of peppers are suitable. In the case of large fruits and vegetables A such as Saijo and melon, it is necessary to widen the width and lengthen it. The fruit vegetable receiving body 8 moves in the traveling direction as the endless traveling rotating body 7 rotates, so that the fruit vegetables A placed on the belt 15 can be conveyed in the direction of arrow a in FIG. As shown in FIG. 1 and FIG. 2, a fruit vegetable mounting portion 16 is set on the upper surface of each belt 15, and a support 17 is provided in the immediate vicinity thereof.

  As shown in FIG. 1, the fruit vegetable receiving body 8 is attached to the endless traveling rotator 7 so that the fruit vegetable mounting portions 16 are aligned in a line in the conveying direction of the fruit vegetable conveying body 9. The belt 15 can be reciprocally rotated in the direction of fruit and vegetable conveyance by the fruit and vegetable conveyance body 9, and rotated (forward rotation) to the side of the fruit and vegetable conveyance direction according to the discrimination result after discrimination of the equal class, Fruit vegetables A can be sent out to the side of the fruit vegetable conveyance direction for sorting. After the sorting, the belt 15 continues traveling along with the subsequent rotation of the endless traveling rotating body 7 until it returns to the fruit mounting area 10, and reverse rotation (reverse rotation). Then, returning to the original position before sending out the fruit vegetables, the fruit vegetable mounting parts 16 of the many fruit vegetable receivers 8 are arranged in one line (including substantially one line) as shown in FIG.

  The fruit and vegetable receiver 8 shown in FIG. 1 has a single belt 13 wound with a belt 15 having the same width as that of the fruit and vegetable receiver 8, but the fruit and vegetable receiver 8 has a horizontal width on one frame 13 as shown in FIG. 11. A plurality of narrow belt winding portions 18 (four in FIG. 11) are provided, and a narrow belt 15 is rotatably wound around the outer periphery of a pair of rotating rollers 14 attached to each belt winding portion 18. It may be a thing. In FIG. 11, four belt winding portions 18 of one frame 13 are slanted, and steps are provided at the front end portion and the rear end portion thereof, so that the belt 15 wound around the outer periphery of the belt winding portion 18 is slanted. There is a step. The fruit vegetable receptacle 8 is attached to the endless traveling rotary body 7 as shown in FIG. The lateral width and length of the belt winding portion 18 in FIG. 11 and the lateral width and length of the belt 15 can be freely designed. For example, the lateral width of the belt winding portion 18 is about 2 cm, and the lateral width of the belt 15 is slightly more than that. It is thin.

  When the width of the belt 15 is wide as shown in FIG. 1, the fruit vegetables A can be placed one by one on each belt (one belt) 15, but when it is narrow as shown in FIG. One fruit vegetable A can be straddled on the belt 15 or more.

  In the fruit vegetable receiver 8 according to the present invention, the horizontal width of each frame 13 is set to be as narrow as, for example, the horizontal width of the belt winding portion 18 in FIG. A pair of rotating rollers 14 may be provided, and a rotating belt having a narrow width may be rotatably wound around the outer periphery of the rotating roller 14. In this case, the horizontal width of the frame 13 and the horizontal width of the rotating belt can also be designed appropriately. Also in this case, one fruit vegetable A can be straddled on two or more belts 15 adjacent to each other.

  When a large number of narrow belts 15 are arranged, two or several adjacent belts 15 can be used as a set of units. In this case, fruit vegetables A are placed for each unit, the belt 15 of the unit on which the fruit vegetables A are placed are simultaneously rotated in the same direction to feed the fruit vegetables A, and the unit is rotated backward for each unit to rotate the fruit vegetables A 16 of the belt 15. Can be aligned in the original position.

(Support)
The support 17 projects upward from the upper surface of the belt 15. This support 17 can be reciprocated in synchronization with the reciprocating rotation of the belt 15 to the side, and serves as a guide for positioning when the fruit vegetables A are placed on the fruit vegetables placing section 16. It is possible to prevent misalignment or overturning of the fruit vegetables A being supported and to carry them, and the fruit vegetables A to be sent to the side by the rotation of the belt 15 can be pushed out.

  The support 17 molded separately from the belt 15 can be attached directly or indirectly to the belt 15 or can be integrated with the belt 15. The lateral width of the support 17 is the same (including substantially the same) as the lateral width of the belt 15, and protrudes upward from the upper surface of the belt 15 in any case. The support 17 serves as a mark when the fruit vegetables A are placed on the belt 15, supports the fruit vegetables A placed on the belt 15 from behind, and the fruit vegetables A fall backward during transportation or are displaced. Can be prevented. Moreover, there is also a function as a pusher when the fruit vegetables A are sent out from the belt 15 to the side pool conveyor 3.

(Fruit vegetables loading part)
The fruit vegetable mounting part 16 may be left as it is with a mark as a mark on the upper surface of the belt 15, or a part of the upper surface of the belt 15 has a structure in which the fruit vegetable A is not easily toppled, It can also be made of a non-slip material. In any case, the position of the fruit vegetable mounting portion 16 is a position where it is supported by the support tool 17 in contact with the support tool 17 behind the fruit vegetable A placed there, or a position slightly away from the tip of the support tool 17. It is desirable to set the position (the position closest to the other side).

(Pin (protrusion))
As shown in FIGS. 2 and 12, a pin (projection) P is provided below each of the belts 15 and protrudes below the frame 13. The downward projecting portion of each projection P is guided by a feed guide rail (outward guide rail: not shown) disposed under the fruit vegetable transport body 9 during the fruit vegetable transport so that it can move obliquely backward (forward travel). As the protrusion P moves, the belt 15 rotates in the same direction (rotated backward: forward rotation), and the fruit vegetables A on the fruit vegetable mounting portion 16 are obliquely rearward while the fruit vegetables are being conveyed. (FIGS. 1 and 3). Further, after the belt 15 of the fruit vegetable receiver 8 rotates and the fruit vegetables A are fed out, the downward protrusion of the protrusion P continues to move in the fruit vegetable conveying direction after the belt 15 of the fruit vegetable receiver 8 has been fed out (the fruit vegetable placement area 10). ), It is guided by a return guide rail (return guide rail: not shown) disposed under the fruit vegetable carrier 9 so that it can move back (reverse) in the reverse direction. With this forward movement, the belt 15 rotates in the same direction (forward rotation), and the fruit-paste mounting portions 16 of the belts 15 of the large number of fruit vegetable receivers 8 return to their original positions before the forward rotation and are in a row or substantially in a row. To be aligned. In this embodiment, the protrusion P is provided on the upper side (upper travel part) of the belt 15, but the protrusion P can also be provided on the lower side (lower travel part) of the belt 15 as shown in FIG. In this case, since the moving direction of the forward guide rail and the moving direction of the belt 15 are opposite to each other, when the belt 15 is moved obliquely rearward, the protrusion P is moved obliquely forward.

(Tracking switch)
A tracking switch 23 (FIGS. 1 and 10) is arranged in front of the fruit and vegetable transfer area 10 of the fruit and vegetable transport body 9. There are two pairs of tracking switches 23. When a large number of tracking switches 23 are attached to an endless traveling body 24 (FIGS. 1 and 10) such as a chain and a timing belt, and the endless traveling body 24 travels and rotates, tracking is performed. The switch 23 moves in the same direction and rotates in a circulating manner. The tracking switch 23 is for roughly selecting the fruit vegetables A to be placed on the fruit receiver 8 in the fruit vegetables loading area 10. For example, the fruit vegetables A are damaged, the color of the fruit vegetables A is bad, or the fruit vegetables A are deformed. In such a case, one or both of the tracking switches 23 of each set can be pressed to perform rough selection. When the tracking switch 23 is pressed, the signal is transmitted to the control unit in the discrimination area 11 to become fruit vegetable selection information.

(Outward guide rail)
In the sorting area 12, the forward guide rail (not shown) is arranged at the location where the pool conveyor 3 is arranged and below the fruit vegetable transporting body 9. The forward guide rail is arranged obliquely rearward with respect to the conveyance direction of the fruit vegetable carrier 9. A switching lever is arranged in front of the conveyance direction of each forward guide rail, and the switching lever switches the moving direction of the protrusion P of the fruit vegetable receiving body 8 based on the determination result in the determination area 11 to receive the fruit vegetables. The belt 15 of the body 8 is rotated and moved to the side of the fruit and vegetables conveyance direction. The switching lever can be switched between a normal position and a switching position. When the switching lever is in the normal position, the protrusion P is passed (straight forward) as it is in the fruit vegetable transport direction, and is switched based on the determination result in the determination area 11. The path of the projection P is switched so that P moves obliquely backward in the fruit and vegetable conveyance direction.

  When the protrusion P goes straight as it is, the belt 15 of the fruit vegetable receiving body 8 does not rotate, and the fruit vegetables A thereon are not sent sideways but pass through the forward guide rail. When the fruit vegetable receiver 8 is transported and the fruit vegetable receiver 8 reaches the fruit delivery position, the switching lever is switched, and the protrusion P moves obliquely backward in the fruit vegetable transport direction along the forward guide rail at that position. . Along with this movement, the belt 15 connected to the protrusion P moves in the same direction as the movement direction of the protrusion P, that is, obliquely rearward in the fruit vegetable conveying direction, and the fruit vegetables A placed on the belt 15 convey the fruit vegetables. It is made to feed into the pool conveyor 3 arrange | positioned in the direction side. In this case, since the speed (inertia) in the conveyance direction conveyed by the fruit vegetable conveyance body 9 is reduced, the fruit vegetables A fed to the pool conveyor 3 are unlikely to fall down.

  The switching control of the switching lever is performed by the control device based on the determination result in the determination area 11.

(Return guide rail)
A return guide rail (return guide body: not shown) is disposed in the transport direction ahead of the sorting area 12 of the fruit vegetable transport body 9 and below the fruit vegetable transport body 9. The return guide rail is disposed obliquely in the opposite direction to the forward guide rail. The fruit vegetable receiver 8 that has delivered the fruit vegetables A to the pool conveyor 3 continues to travel as the endless traveling rotating body 7 travels, and returns to the fruit vegetable loading area 10, while the fruit vegetable receiver 8 that has delivered the fruit vegetables A has a protrusion. P is guided by the reverse guide rail and moves in the opposite direction to the forward movement. Along with this movement of the protrusion P, the belt 15 rotates in the same direction and returns to the position before the delivery of the fruit vegetables, so that the fruit vegetable mounting parts 16 (FIG. 1) of the many fruit vegetable receptacles 8 are in one line (including substantially one line). They are all aligned.

(Pool conveyor)
The pool conveyor 3 is also a belt conveyor type, and has a length and a width that can pool a large number of fruit vegetables A. The pool conveyor 3 rotates each time the fruit vegetable A is sent out from the fruit vegetable receiver 8 so that the fruit vegetables can be taken over one by one. By this rotation, the fruit vegetables A can be sent to the relay device 4 one by one. The pool conveyor 3 may be moved after a predetermined amount of fruit vegetables A are pooled.

  In the case of FIG. 1, the pool conveyor 3 is arranged in parallel to be perpendicular to the fruit and vegetable transport body 9 on the side of two or more places on the side of the fruit and vegetable transport body 9. In FIG. 1, the pool conveyors 3 are provided in the same number of fruit vegetables A as the same class, so that the fruit vegetables A can be sent to the respective pool conveyors 3 by class. The pool conveyor 3 can also be arranged slightly obliquely rearward or obliquely forward with respect to the fruit vegetable carrier 9.

  It is not necessary for all the pool conveyors 3 to have the same number of belts, widths, lengths, etc., and the pool conveyors 3 that take over a large number of equal grade fruits and vegetables A can be increased in number, widened in width, If the length is increased, many fruit vegetables A can be reliably pooled. Even if the number of the pool conveyors 3 that take over the same-class fruit vegetables A with a small number of fruit vegetables A is reduced, the width is narrowed or shortened, the fruit vegetables A can be reliably pooled.

  The pool conveyor 3 can be rotated at all times, but when the fruit vegetables A are not sent, the pool conveyor 3 is temporarily stopped and kept waiting, and when the fruit vegetables A are fed from the fruit vegetable receptacle 8, the fruit is rotated by one fruit vegetable. Thus, it can be controlled so that a space for the fruit vegetables A is secured. The rotation control of the pool conveyor 3 is also performed by the control device based on the determination result in the determination area 11.

(Fruit vegetables sorting)
In the fruit and vegetable transporting area 9 of the fruit and vegetable transporting body 9, the fruit and vegetable A placed on the fruit and vegetable mounting part 16 of the belt 15 of the fruit and vegetable receiving body 8 is transported in the direction of arrow a in FIG. 1 by the traveling rotation of the endless traveling rotating body 7. In the discrimination area 11, the shape, size, etc. are automatically measured by the measuring instrument (measuring instrument) B and discriminated according to the equal class. After discrimination, the belt 15 rotates diagonally backward in the fruit and vegetable conveyance direction according to the discrimination result. Thus, the fruit vegetables A on the belt 15 are sent out in the rotation direction according to the equal class, and are taken over by the pool conveyor (article receiver) 3 arranged on the side of the fruit vegetable transporter 9 and sorted according to the equal class.

  In FIG. 1, three pool conveyors 3 are arranged for each equal class. Although the pool conveyor 3 of FIG. 1 is arranged orthogonally to the side of the fruit and vegetable transport body 9, the orientation of the pool conveyor 3 with respect to the fruit and vegetable transport body 9 can also be disposed obliquely toward the rear or the front.

  As shown in FIGS. 1 and 10, the fruit and vegetable receiver 8 attached to the endless traveling rotator 7 obliquely rearwardly, when the belt 15 rotates obliquely rearward, the fruit and vegetables A placed on the fruit and vegetables mounting portion 16 are in the same direction. Since it is sent out and transferred to the pull conveyor 3 (takes over), the sending speed of the fruit vegetables A is decelerated, and when transferring to the pull conveyor 3, the inertia at the time of sending is reduced, and the fruit vegetables A are less likely to fall over ( do not do).

  When fruit vegetables A are placed on several adjacent belts 15, several belts 15 on which fruit vegetables A are placed are simultaneously rotated in the same direction and sent out.

  The selection of the fruit vegetables A is an explanation when the fruit vegetable receiver 8 is attached obliquely rearward to the endless traveling rotator 7. The fruit vegetable receiver 8 is attached orthogonally to the endless traveling rotator 7. It is also possible to attach it obliquely forward to some extent. In these cases, the speed of the fruit vegetable A sent out from the fruit vegetable receiver 8 is reduced, and when transferring to the pull conveyor 3, the inertia at the time of feeding is reduced, so that the fruit vegetable A is less likely to fall. It is desirable to provide a speed reducing body between the body 8 and the pull conveyor 3, or to make other means, for example, the side of the fruit vegetable receiving body 8 (on the side of the pull conveyor 3) is gradually rising. .

(Relay device)
The relay device 4 is provided in front of the pool conveyor 3, takes over the fruit vegetables A sent out from the pool conveyor 3, and sends them to the quantity adjusting device 5 (FIG. 3) below the pool conveyor 3.

  The relay device 4 shown in FIG. 3 is a belt conveyor in which a belt 32 is wound around the outer periphery of two pairs of rotating rollers 31a and 31b, and fruit vegetable support pieces 33 for supporting the fruit vegetable A on the outer periphery of the belt 32 are equally spaced. Installed in. In the example shown in FIG. 3, the relay device 4 having the same structure is arranged to face each other in a vertically oriented state so that the fruit vegetables A are supported between both the relay devices 4. The two relay apparatuses 4 are configured such that one (the relay apparatus on the left side in FIG. 3) rotates clockwise and the other (the relay apparatus on the right side in FIG. 3) rotates counterclockwise.
