A chain 3 is wound around. An electric motor 14 that is a drive source of the drive sprocket 12 is also attached to the conveyor frame 10. The electric motor 14 is screwed (or bolted) to the conveyor frame 10 via a bracket 28. The transport chain 3 moves clockwise in FIG.

  Various frames and cover bodies constituting the casing are attached to the conveyor frame 10. Two outer frame support frames 20 are arranged so as to sandwich the transport chain 3, and the outer frame support frames 20 are attached to the conveyor frame 10 with screws (or bolts) not shown. An outer frame body 25 is attached to the upper surface of the outer frame body support frame 20 in order to cover the left and right portions of the tray 2 in the transport direction. The upper surface of the outer frame body 25 is almost at the same height as the lower surface of the tray 2. In this embodiment, the outer frame body support frame 20 also uses the same molding frame as the conveyor frame 10 as a material to reduce the part cost.

  An end cover body 18 that covers the transport end portion of the transport chain 3 (tray 2) and the drive sprocket 12 is attached to the conveyor frame 10 via an outer frame body support frame 20 with screws (or bolts) (not shown). The end cover body 18 may be placed so as to engage with the end portions of the two outer frame body support frames 20.

Note that the conveyance start end of the conveyance chain 3 (tray 2) and the upper surface of the driven sprocket 13 are covered with a supply hopper 4.

  The supply hopper 4 and the determination casing 6 are attached to the conveyor frame 10 via the outer frame body support frame 20 and the outer frame body 25 with mounting screws 44 and 66, respectively.

  In this manner, the transport chain 3, the electric motor 14, the determination casing 6, the support frame 11, the supply hopper 4, the end cover body 18, the start end cover body 19, and the like are intensively attached to the conveyor frame 10. Therefore, the sorting device 1 as a whole can be easily downsized and can be easily carried.

  The tray 2 is attached to the transport chain 3 at regular intervals. In the description, the upper and lower sides are described with reference to the time when the tray 2 is positioned and transported above the transport chain 3. When the transport chain 3 moves from the downstream side to the upstream side in the tray transport direction, since the tray 2 is located below the transport chain 3, the top and bottom are reversed.

  The tray 2 has a mounting surface 21 on which one cherries S are placed. The tray 2 is made of a plastic material, and the mounting surface 21 is used to stably transport the cherries S to a substantially central portion in the plan view (in the embodiment, a position slightly deviated to the right in the transport direction from the central portion). Are formed in a generally pyramid shape or a mortar shape so as to be inclined downward from the peripheral portion toward the recess. Thereby, even if the cherries S are placed out of the dents of the tray 2, they can move to the dents by their own weight.

  As shown in FIG. 7, a column portion 22 is integrally provided at the lower portion of the tray 2 (on the side opposite to the mounting surface 21). A slit 23 is formed in the lower surface of the column portion 22 by cutting. The slit 23 is formed long in the direction perpendicular to the tray conveyance direction through the center of the lower surface of the support column 22, and penetrates the peripheral surface of the support column 22.

  As is well known, the transport chain 3 has an oblong inner plate 31 and an outer plate 32 connected by a shaft 34 inserted into a roller 33 (the boss is not shown). The tray 2 is attached to the transport chain 3 via an attachment described later, and a connecting piece portion 35 for attaching the attachment is formed on the outer plate 32. As shown in FIG. 8, the connecting piece 35 is formed by bending the upper end portion of the outer plate 32 in the horizontal direction.

  On the upper surface of the connecting piece 35, the first attachment 15 and the second attachment 16 are alternately attached along the tray conveying direction. A projecting piece 17 is formed on the first attachment 15 by bending one end of the first attachment 15 upward. The protruding piece 17 is formed long in a direction orthogonal to the tray conveying direction.

  The projecting piece portion 17 is inserted into a slit 23 formed in the column portion 22 of the tray 2. A roll pin 27 extending parallel to the tray conveying direction is inserted into the support column 22, and the roll pin 27 passes through the protruding piece 17. The tray 2 (the column portion 22) is configured to be able to undulate in the direction (left and right) orthogonal to the tray conveyance direction with the roll pin 27 as the center. When the tray 2 is raised and lowered, the projecting piece 17 functions as a guide. In order to tilt the tray 2 greatly while having a compact structure, an end 17a of the projecting piece 17 in a direction orthogonal to the tray transport direction and an end 22a of the support column 22 in the tilt direction (right side of the tray transport direction) Is cut into a tapered shape.

  A guide frame 24 that prevents tilting in the direction (left and right) perpendicular to the transport direction of the tray 2 is disposed inside the outer frame support frame 20 except for the portion where the sorting chute 7 is provided. . The guide frame 24 is a frame that is long in the tray conveyance direction, and is disposed on the left and right of the support column 22 below the tray 2. The upper surface of the guide frame 24 is close to the lower surface of the tray 2 and prevents the tray 2 from falling to the left and right in the tray conveyance direction by contacting the guide frame 24. The guide frame 24 is attached to the conveyor frame 10 with screws via a bracket (not shown).

  That is, in the part where the sorting chute 7 is not provided, the guide frame 24 is arranged so as to sandwich the left and right sides of the tray 2 in the tray conveying direction in the column portion 22 of the tray 2, so that the tray 2 is maintained in the standing posture. Be transported. On the other hand, in the part where the sorting chute 7 is provided, the guide frame 24 is disposed only on the left side of the tray 2 in the tray conveying direction in the column portion 22. Blocked and transported.

  The outer frame body 25 described above is formed wide so as to cover both the outer frame body support frame 20 and the guide frame 24 at the portion where the guide frame 24 is disposed, and the guide frame 24 is not disposed. In the part, that is, the part where the sorting chute 7 is provided, the outer frame body 25 is formed with a narrow width (a reference numeral 25a is attached to the narrow outer frame body). Therefore, a gap is formed between the inner side surface of the outer frame body 25a and the side surface of the tray 2.

  A supply hopper 4 is provided above the upstream side in the tray conveyance direction. The supply hopper 4 has a flat plate shape having substantially the same width dimension as the width dimension of the casing of the sorting device 1 (dimension in the direction orthogonal to the tray conveying direction). Ribs 41 are formed on the outer peripheral edge of the supply hopper 4 to prevent the cherries S from falling. A part of the rib 41 is cut away to form an outlet of the supply hopper 4, and the supply hopper 4 is tapered toward the outlet. The cherries S placed on the supply hopper 4 are supplied one by one from the outlet of the supply hopper 4 to the tray 2 being conveyed below the supply hopper 4 by an operator by hand.

  Engaging portions 42 for attaching the supply hopper 4 to the outer frame body 25 are provided at the left and right lower portions of the supply hopper 4. A guide rail 43 that slidably supports the supply hopper 4 via the engaging portion 42 is formed on the outer frame body 25, and the supply hopper 4 slides in the tray conveyance direction by the guide rail 43. . As shown in FIG. 6, the supply hopper 4 is configured to be movable between a working position protruding outward from the casing and a storage position arranged on the casing by sliding. An attachment screw 44 for fixing the position of the supply hopper 4 is detachably provided on the engagement portion 42. By loosening the attachment screw 44, the supply hopper 4 (engagement portion 42) can slide. It becomes possible.

  The supply hopper 4 is fixed to a work position that protrudes outward from the upstream side in the tray conveying direction when sorting the cherries S. Since the position of the supply hopper 4 can be freely slid by loosening the mounting screw 44, the amount of protrusion of the supply hopper 4 to the outside of the housing, in other words, the outlet of the supply hopper 4 and the judgment casing 6 Can be set freely. That is, when it is desired to shorten the conveyance time by shortening the interval between the outlet of the supply hopper 4 and the determination casing 6, or when the supply hopper 4 is installed at an installation location where the supply hopper 4 cannot be protruded outwardly from the housing. The working position of the supply hopper 4 can be adjusted.

  On the other hand, when the sorting device 1 is stored, the supply hopper 4 is slid and moved to a work position where the supply hopper 4 is located on the housing. Since the supply hopper 4 does not protrude outward (or hardly protrudes) in the storage position, the storage space for storing the sorting device 1 can be made compact. In addition, when the supply hopper 4 is in the storage position, the tray 2 located upstream of the determination casing 6 is covered, so that the supply hopper 4 also acts as a cover for covering the tray 2. Further, since the supply hopper 4 can be stored without removing the supply hopper 4, there is no need to remove the supply hopper 4 when storing the sorting device 1, and there is no trouble of storing the supply hopper 4 separately. .

  The guide rail 43 that slidably supports the supply hopper 4 is provided on the outer frame body 25 that covers the outer frame body support frame 20 that is a housing. That is, since the guide rail 43 is formed using the outer frame body 25 provided on the outer frame body support frame 20 having high rigidity, the supply hopper 4 can be slid stably.

  The determination casing 6 is formed in a tunnel shape so as to cover the transport chain 3 and the tray 2 from above, and is attached to the conveyor frame 10 via the outer frame body support frame 20. Openings 61 for allowing the cherries S to pass through are cut out in a triangular shape on the upstream side surface and the downstream side surface in the tray conveying direction in the determination casing 6. When an optical sensor is employed as the determination means 5 as described later, it is necessary to make it less susceptible to the influence of external light. The opening area can be reduced while avoiding the collision of the cherries S (conveyed object).

  The determination casing 6 includes a determination means 5 that is a means for measuring the size and sugar content of the fruit portion of the cherries S, and a controller 62 as a management computer. The determination means 5 is provided with a light source that irradiates the cherry S with near infrared rays, a light receiving portion that receives the transmitted light, and the like. The determination means 5 determines the rank of the cherries S based on the size and sugar content measurement data.

  In this embodiment, the cherries S are classified into four ranks according to the sugar content and size of the cherries S. Note that the determination result of the determination unit 5 is stored in the controller 62. The controller 62 drives the corresponding solenoid 8 so as to discharge the cherries S to the sorting chute 7 corresponding to each rank in accordance with the determination result.

  On the side surface of the determination casing 6, a power switch 63 is provided as an operation unit that turns on and off the driving of the transport chain 3. In addition, on the upper surface of the determination casing 6, a touch panel 64 for operating the determination unit 5 and an emergency stop button 65 are disposed as operation units.

  As described above, by providing the determination casing 6 with the controller 62 and the determination means 5 and arranging the various operation units 63, 64, 65 in a concentrated manner, electrical wiring can be performed collectively. Therefore, it is possible to reduce the labor and man-hours for wiring and reduce the cost, and it is possible to contribute to the downsizing of the entire apparatus. In addition, since the various operation units 63, 64, and 65 are intensively arranged in the determination casing 6 that is arranged in the approximate center in the tray conveyance direction, the operator can perform various operations without greatly changing the posture. Can reduce the burden of operation.

  Four sorting chutes 7 are juxtaposed along the transport direction on the downstream side of the determination casing 6 in the tray transport direction. The sorting chute 7 is disposed on the right side in the tray transport direction with respect to the transport chain 3, and the discharge solenoid 8 is disposed on the left side in the tray transport direction with respect to the transport chain 3. As shown in FIG. 5, the sorting chute 7 is a plate-like member and is inclined so that the cherries S dropped from the inclined tray 2 are rolled (flowed down) into the container 71.

  In the embodiment, the four sorting chutes 7 are formed by standing and separating three partition portions 73 on one plate-like member. The plate-like member constituting the sorting chute 7 is attached to the conveyor frame 10 so that the inclination angle can be adjusted steplessly between the horizontal state and the inclined state where the outlet side is lower than the inlet side. Yes. Note that the four sorting chutes 7 may not be configured by a single plate-shaped member, but may be configured by independent plate-shaped members, or the inclination angle may be individually adjusted.

  The entrance (upper end) of the sorting chute 7 is disposed at a position closer to the tray 2 than the narrow outer frame body 25a. When the four discharge solenoids 8 receive a command from the controller 62, the plunger 81 of the discharge solenoid 8 extends to a position to press the column portion 22 of the tray 2, and when the command from the controller 62 is released, the plunger 81 The support 22 is configured to return to a position where it is not pressed.

  The ranks of the cherries S placed on the tray 2 are determined individually by passing through the determination casing 6, and the timing at which the tray 2 reaches the sorting chute 7 of the corresponding rank (the tray 2 (Calculated from the conveyance speed), the controller 62 issues a discharge operation command to the corresponding discharge solenoid 8.

  When receiving a command for the discharge operation, the plunger 81 of the discharge solenoid 8 extends to a position where the plunger 22 of the tray 2 is pressed. Since the guide frame 24 is not disposed at the portion where the sorting chute 7 is provided, the tray 2 pressed by the plunger 81 tilts toward the sorting chute 7, and the cherry S placed on the tray 2 is moved to the sorting chute 7. Fall into. Below the sorting chute 7, a container 71 is placed in advance for each sorting chute 7, and the cherries S slide down under the outer frame body 25 a and are accommodated in the container 71.

  On the inner side of the narrow outer frame body 25a, three fall prevention bodies 72 that prevent the tray 2 from tilting are provided at intervals along the tray conveyance direction. The fall prevention body 72 is disposed on the entrance side (upper end portion) of each sorting chute 7 so as to divide the adjacent sorting chutes 7 and is attached to the outer frame body support frame 20. The fall prevention body 72 has an L shape and is attached so as to protrude from the outer frame body 25a to the tray 2 side.

  The interval L between the overturn prevention bodies 72 in the tray conveyance direction is set to be smaller than the size of two trays in the tray conveyance direction. Therefore, when the tray 2 is tilted by the discharge solenoid 8, it is possible to prevent the front and rear trays 2 adjacent to the tilting tray 2 from being accidentally overturned in conjunction with the tilting falling tray 2. That is, at the entrance of the sorting chute 7, only one tray 2 can be tilted.

  For example, if the trays 2 are arranged with a large distance in the front and rear direction in the tray conveyance direction, the front and rear trays 2 adjacent to the fall tray 2 can be prevented from rolling with the fall tray 2. In this case, the sorting processing capacity (the number of processes per unit time) decreases. On the other hand, as described above, when the fall prevention body 72 is provided, the front and rear trays 2 adjacent to the fall tray 2 are accompanied by the fall tray 2 even if the trays 2 are arranged close to each other in the transport direction. Therefore, it is possible to reliably prevent rolling and thus prevent erroneous discharge without lowering the sorting processing capacity.

  The lower surface of the fall prevention body 72 is arranged to be higher than the upper surface of the fall tray 2. Therefore, even if the fall tray 2 is once tilted, it passes through the lower surface of the fall tray 2 even if the fall prevention body 72 is downstream of the fall position. The tray 2 is returned to the upstream side of the tray conveyance by the drive sprocket 12. At this time, all the trays 2 are automatically corrected to a downward posture in which the placing surface 21 is downward due to gravity. That is, since a special mechanism for returning the lying tray 2 to the standing posture is unnecessary, the discharging means may be a simple mechanism that only tilts the tray 2.

  Therefore, a solenoid having a simple structure can be adopted as the discharging means, and the cost can be reduced. Further, since the solenoid is lighter and smaller than an electric motor, a cylinder, or the like, it can be compactly attached to the conveyor frame 10 without protruding from the casing, and is excellent in design.

  As described above, in the present embodiment, the tray 2 on which the cherries S are placed, the transport chain 3 for transporting the plurality of trays 2, the electric motor 14 for driving the transport chains 3, and the cherries S on the tray 2 In a sorting apparatus 1 provided with a determination casing 6 having a determination means 5 for determining quality, the conveying chain 3, the electric motor 14, and the determination casing 6 are provided on one conveyor frame 10. Therefore, since the transport chain 3, the electric motor 14, and the determination casing 6 can be compactly arranged on one conveyor frame 10, the sorting device 1 can be configured in a tabletop manner. Since the sorting apparatus 1 can be placed on the work table T that is easy to work by configuring the tabletop, the installation space, work space, and storage space can be easily secured. Moreover, since the conveyance chain 3, the electric motor 14, and the determination casing 6 are concentrated on the conveyor frame 10, the sorting device 1 can be easily carried.

  Further, a support frame 11 that supports the conveyor frame 10 from below is provided, and a pair of support frames 11 are connected to both ends of the conveyor frame 10 in an H shape in a plan view. While the structure can stably support the frame 10, the overall height of the sorting device 1 can be kept low. Therefore, the sorting device 1 can be placed on the upper surface of the work table T.

  Further, since the conveyor frame 10 and the support frame 11 are formed by cutting the same molding frame, as a material of the conveyor frame 10 and the supporting frame 11, for example, a molding frame made of aluminum alloy Is applied, both the conveyor frame 10 and the support frame 11 can be formed by cutting one molding frame into a required length, so that the manufacturing cost can be reduced.

  Further, the determination casing 6 is provided so as to cover the middle part of the transport chain 3 from above, and the determination casing 6 is provided with the operation portion of the transport chain 3 or the determination means 5. In addition, electrical wiring and the like can be intensively arranged, reducing the labor and man-hours of wiring, reducing costs, and contributing to downsizing of the entire apparatus.

  Further, since the power switch 63, the emergency stop switch 65, or the touch panel 64 is arranged in the determination casing 6, electrical wiring and the like can be centrally arranged in the determination casing 6, and the wiring The labor and man-hours can be reduced, the cost can be reduced, and the overall apparatus can be made compact.
