Description

  The present invention provides a first transport body that transports and separates an object, and a plurality of objects that are provided on the first transport body at regular intervals in the transport direction and send the object from the first transport body in a substantially orthogonal direction at a desired position. The present invention relates to an object sorting device provided with a delivery belt.

  A first conveyor (first transport body) provided in a conventional object sorting apparatus is slidable in a longitudinal direction on a plurality of elongated slats for placing an object and the slats as shown in Patent Document 1, for example. A press shoe (sending part) or the like fitted is provided. The pressing shoe is for sending the object from the first conveyor in a substantially orthogonal direction at a desired position, and includes a protrusion for pressing the object from the rear side. In addition, a second conveyor (second conveyance body) that further conveys an object in the delivery direction is provided at a destination where the object is delivered from the pressing shoe. A plurality of storage shelves for storing objects are provided further ahead of the second conveyor. An object is stored in this storage shelf using a crane provided separately.

  When this object sorting apparatus sorts objects on a plurality of rows of storage shelves, the object is placed on the first conveyor and conveyed. At this time, since the slat is an elongated structure, the object is placed on the plurality of slats. When the object reaches a desired position, the protrusion of the pressing shoe comes into contact with the back surface of the object and sends the object from the slat. The delivered object is transferred to the second conveyor and conveyed in the delivery direction. Then, the object is lifted by the crane and stored in a desired position on the storage shelf near the end point of the second conveyor.

JP-A-11-157640

In the object sorting apparatus configured as described above, when an object is sent out at a desired position in a direction substantially perpendicular to the conveying direction, the object is pushed by the pressing shoe from the back side and slides on the slat to the second conveyor. It is sent out in parallel. That is, for example, when an elongated object (that is, an object having a large aspect ratio) is transported by the first conveyor, when the object is placed so that the major axis of the object is in the transport direction of the conveyor, the elongated object is It is pushed in the minor axis direction and sent out to the first conveyor. The 2nd conveyor is provided in the direction which sends out an object, ie, the direction orthogonal to the 1st conveyor. Therefore, it is necessary to set the width of the second conveyor to be larger than the long diameter of the object, and it is necessary to ensure a large space for the entire object sorting apparatus.
Accordingly, an object of the present invention is to provide an object sorting device with reduced space.

For this reason, the invention according to claim 1 is a first transport body that transports and separates an object;
In an object sorting apparatus comprising a plurality of delivery belts provided on the first transport body at regular intervals in the transport direction and for feeding the object from the first transport body in a substantially orthogonal direction at a desired position.
The width of the delivery belt is configured to be smaller than 1/3 of the long diameter of the object placed thereon, and a protrusion for supporting the object when the delivery belt sends out the object is provided on the delivery belt. ,
The plurality of delivery belts on which one object is placed sequentially deliver the objects when reaching a desired position.

  According to a second aspect of the present invention, in the object sorting device according to the first aspect, one protrusion is provided on the delivery belt, and the object is moved backward when the delivery belt sends out the object. More supportive.

  According to a third aspect of the present invention, in the object sorting device according to the first aspect, a plurality of the protrusions are provided on the delivery belt and support the object from below.

  According to the first aspect of the present invention, the first transport body that transports and sorts the object and the first transport body are provided on the first transport body at regular intervals in the transport direction, and the object is placed at a desired position. In an object sorting device comprising a plurality of delivery belts that are fed out in a substantially orthogonal direction from the feed belt, the width of the delivery belt is made smaller than ３ of the major axis of the object placed thereon, and the delivery belt sends out the object Protrusions that support the object are provided on the delivery belt, and the plurality of delivery belts on which one object is placed sequentially deliver the object when it reaches a desired position. Therefore, the first conveyance is carried out across the plurality of delivery belts. When an object placed along the body conveyance direction is sent out from the delivery belt, the delivery belt on which the leading portion of the object is placed starts feeding first and is provided adjacent to the delivery belt. Subsequent sending Belt is, since the start of feeding a sequential predetermined intervals, the object is rotated to direct the head portion in the feeding direction in a state of being placed on a plurality of delivery belts. Furthermore, since the delivery roller further conveys the leading portion of the object in the delivery direction, the object is conveyed by changing the conveyance posture by approximately 90 degrees. For this reason, when another conveyance body is provided in the direction perpendicular to the first conveyance body at the destination, the width can be set smaller than the major axis of the object. Therefore, it is possible to provide an object sorting device with reduced space.

  In addition, since the protrusion is provided on the delivery belt, the protrusion supports the object even if the object tries to stay in place by inertia force when the delivery belt starts the delivery operation. Therefore, the object can be reliably conveyed by the delivery belt. Further, since the object is placed on the delivery belt, when the object is sent out from the first transport body, the object is not slid out on the first transport body, and the upper surface of the first transport body and the object No frictional force is generated between the bottom surface. Therefore, it is possible to provide an object separation device that can separate an object while maintaining the quality without impairing the quality of the bottom surface of the object due to friction.

  According to the second aspect of the present invention, one protrusion is provided on the delivery belt, and when the delivery belt sends out the object, the object is supported from the rear, so when the delivery belt starts the delivery operation. In addition, in the unlikely event that an object tries to stay in place due to inertial force, the protrusion supports the object from the rear, so that the object can be reliably conveyed on the delivery belt. Further, since the protrusion pushes the object from the back surface, the object can surely move from the delivery belt to the next process.

  According to the third aspect of the present invention, the plurality of protrusions are provided on the delivery belt and support the object from below. Therefore, when the delivery belt starts the delivery operation, the object should be caused by inertial force. Even when trying to stay in place, the plurality of protrusions can support the object from below and reliably send the object to the next process.

It is a top view of the fruit selection machine as an object classification device of this invention. It is the partially expanded plan view. (A) is X sectional view taken on the line of FIG. 2, (b) is a Z arrow top view of (a). (A) is a top view inside a 1st conveyance conveyor, (b) is the Y arrow sectional drawing. (A)-(c) is for demonstrating the operation | movement which sorts a cucumber with a fruit selection machine. It is a schematic sectional drawing of the delivery belt of another example of this invention.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view of a fruit selecting machine that sorts cucumbers (objects) C by size (grade) as an example of the object sorting apparatus of the present invention. The fruit selection machine 1 includes a first conveyor (first transport body) 10 and second conveyors (second transport bodies) 14A, 14B, and 14C in a direction orthogonal to the transport direction J of the conveyor. The fruit selector 1 is divided into three zones, zone P, zone Q, and zone R, from the entry side to the exit side. Zone P is an area where the cucumber C delivered by the worker from the farm is placed on the first conveyor 10. The zone Q is an area for measuring the position information of the cucumber C (which delivery belt 13 is placed on the first conveyor 10) on the first conveyor 10 and the size of the cucumber C. The zone R is an area where the cucumber C whose size is specified is sorted and sent from the first conveyor 10 to the second conveyors 14A (large size), 14B (medium size), and 14C (small size).

  The zone Q includes a position detection unit 11 and a grade measurement unit 12. The position detecting means 11 optically reads the position information of the cucumber C on the first conveyor 10 (where it is placed on the first conveyor 10) together with a white mark W to be described later. The grade measuring means 12 is for optically measuring the size of the cucumber C. The position detecting means 11 includes a light that illuminates the first conveyor 10 from above, a dedicated camera, and the like. Further, the grade measuring means 12 includes another light that illuminates the first conveyor 10 from above and a dedicated camera. The information obtained by the grade measuring means 12 is transmitted to a control means (not shown) provided separately, in which the grade of the cucumber C is specified as large / medium / small, and obtained from the position detecting means 11. The cucumber C is combined with the position information on the first conveyor 10 to obtain one cucumber C data. Based on this data, an instruction is sent to the first conveyor 10 as to which of the second conveyors 14A, 14B, and 14C the cucumber C is to be sent.

  In the zone R, a plurality of cucumbers C conveyed on the first conveyor 10 are sent out from the first conveyor 10 to one of the second conveyors 14A, 14B, 14C based on an instruction from the control means.

  Next, the structure of the fruit selection machine 1 will be described in detail. The fruit selection machine 1 includes a first conveyor 10 that conveys and separates the cucumber C, a position detector 11 that detects the position of the cucumber C that is conveyed, a grade measuring means 12 that measures the size of the cucumber C, and a cucumber C A delivery belt 13 for delivering C, a delivery roller unit 23 for receiving and further transporting cucumber C delivered from the delivery belt 13, and a plurality (three in this example) of second rollers ahead of the delivery roller unit 23 Conveyors (second transport bodies) 14A, 14B, 14C, a drive unit that drives the first conveyor 10, gears, and the like are provided.

  As shown in FIG. 2, the delivery roller unit 23 is composed of four rows of rollers. The delivery roller unit 23 includes a plurality of plastic rollers 23b rotatably on a metal support shaft 23a. The roller 23b has a plurality of short divided rollers loosely fitted on the support shaft 23a. It is also slidable in the axial direction. Both ends of the support shaft 23 a are fixed to the frame of the feed roller unit 23. A wide belt is pressed against all the rollers 23b by the pressing roller below the rollers 23b. The wide belt is configured to rotate by a driving roller (not shown). That is, the roller 23b is rotated by the belt pressed from below. Magnets M1 are fixed to both ends of the support shaft 23a. Then, by attaching the magnet M2 having the same magnetic pole as that of the magnet M1 to the outside of the roller 23b closest to the magnet M1, the magnet M1 and the roller 23b to which the magnet M2 is attached repel each other and always have a certain distance or more. Can keep you. All the four rows of rollers 23b have this configuration. Magnets M1 and M2 are permanent magnets.

  Further, even if the roller 23b attached with the magnet M2 receives a certain force and approaches the magnet M1, the repulsive force of both magnets can be driven away from the roller 23b against the force.

  The first conveyor 10 includes a plurality of delivery belts 13. The delivery belt 13 is provided so that the delivery direction is orthogonal to the conveyance direction J of the first conveyor 10, and is provided at regular intervals d throughout the first conveyor 10. The two delivery belts 13 are attached to the unit base 25 as a set. The delivery belt 13 is composed of a pair of rollers 20a and 20b and a green belt 22 wound around them. The belt 22 is preferably made of a non-slip material (a material having a rough surface and a high frictional resistance). A rectangular parallelepiped protrusion 15 is fixed on the surface of the belt 22. It is desirable that the width of the protrusion 15 is approximately the same as the width of the belt 22 and the height of the protrusion 15 is approximately the same as the diameter of the cross section of the cucumber C. Further, on the surface of the belt 22, a white line (mark W) and a black line (mark B) are provided in a straight line in the conveying direction of the first conveyor 10 on both sides at a certain distance from the protrusion 15. These lines are formed by applying paint or the like. On the other hand, the rollers 20a and 20b are rotatably supported by the rotation shafts 21a and 21b, respectively, and both ends of the rotation shafts 21a and 21b are fixed to the unit base 25. The rollers 20 a and 20 b and the rotation shafts 21 a and 21 b are provided for each belt 22. Accordingly, each delivery belt 13 can move independently.

  By the way, the width l of the delivery belt 13 is configured to be smaller than 1/3 of the long diameter L of the cucumber C placed thereon. In addition, when the delivery belt 13 delivers the cucumber C, a protrusion 15 that supports the cucumber C is provided on the delivery belt 13. One cucumber C is placed on a plurality (three in this example) of delivery belts 13.

  The second conveyors 14A, 14B, and 14C are for receiving the cucumber C sorted by size and packing it for shipping. The upstream second conveyor is a continuous operation, and the downstream second conveyor is an intermittent operation that operates only when the cucumber C is fed out. The second conveyors 14A, 14B, and 14C are configured by winding a wide rubber belt around two rollers. One of the two rollers is a driving roller and the other is a driven roller. The timing for intermittent operation is instructed by the control means.

  As shown in FIG. 3, a resin guide bar (round bar) 31 is provided on the back side of the delivery belt 13. Specifically, a round hole is formed in the center of the belt 22 in the width direction, and the guide rod 31 is passed through the round hole. An end portion of the guide bar 31 is fixed to a resin fixing plate 32. By fixing the fixing plate 32 to the back surface side of the belt 22, the belt 22 and the guide rod 31 are configured to move together. The guide bar 31 is long enough to reach guideways 40A and 40B described later. A long hole 25 </ b> A is formed in the lower plate of the unit base 25. The long hole 25 </ b> A is formed along the moving direction of the belt 22 and along the center line of the belt 22. The length of the long hole 25A is set to a distance that the protrusion 15 moves when the delivery belt 13 sends out the cucumber C or more. And the guide rod 31 is loosely fitted in this long hole 25A.

  Endless chains 26 are provided along the transport direction J on both sides in the transport direction J of the first conveyor 10, and the unit base 25 is fixed on the endless chain 26. Specifically, a screw hole is formed in a bracket 27 provided in the endless chain 26, and a bolt 28 is passed therethrough and attached to the front and rear side surfaces in the transport direction J of the unit base 25.

  The endless chain 26 is configured to engage with gears respectively provided on both sides of the front and rear ends of the first conveyor 10. A drive shaft is attached to the pair of gears on the first conveyor 10 entrance side. These gears, drive sources, chains, etc. are covered with a case (not shown). In addition, inside the case, a plurality of unit bases 25 folded back at the terminal end of the first conveyor 10 are conveyed in an upside down direction toward the entry side of the first conveyor 10.

  In this example, two delivery belts 13 are attached to the unit base 25 as one unit, but the number of delivery belts 13 constituting one delivery belt unit is the number of gears at the front and rear ends of the first conveyor 10. Depends on the diameter. That is, if the gear diameter is large, the curvature that the delivery belt unit follows increases, so the number of delivery belts 13 per unit can be increased. If the gear diameter is small, the delivery belt unit follows. Therefore, the number of delivery belts 13 per unit is reduced.

  A delivery mechanism as shown in FIG. 4 is provided on the inner side (back side) of the first conveyor 10. This delivery mechanism is for operating the delivery belt 13 to deliver the cucumber C toward the delivery roller unit 23. The delivery mechanism is provided inside the first conveyor 10 and immediately before each delivery roller unit 23. The delivery mechanism includes a drive pulley 44, a driven shaft 43, an auxiliary belt 42 wound around both of them, and the like. The drive pulley 44 is rotated by a motor (not shown). A direction switching plate 41 is provided in the vicinity of the driven shaft 43 so as to be movable up and down in the vertical direction. In the front-rear direction of the direction switching plate 41, guideways 40A and 40B are provided. The guide bar 31 moves in the guide ways 40A and 40B. The guideways 40A and 40B, the direction switching plate 41, the driven shaft 43, and the drive pulley 44 are provided on the instruction plate 45 in the case of the first conveyor 10.

  The direction switching plate 41 is for switching the direction of the guide bar 31 that has moved in the guide way 40A along the transport direction J of the first conveyor 10 between the a direction and the b direction. When the direction switching plate 41 rises to a predetermined height, the guide bar 31 comes into contact with the direction switching plate 41 and is guided in the direction of arrow a. Then, it further proceeds in the direction a while being urged by the rotating auxiliary belt 42. When the guide bar 31 performs such an operation while the first conveyor 10 operates in the transport direction J, the belt 22 moves in the direction of feeding the cucumber C toward the feed roller unit 23. On the other hand, in the state where the direction switching plate 41 is lowered, the guide rod 31 does not contact the direction switching plate 41 but goes straight (in the direction of arrow b) and proceeds to the guide way 40B. Does not move in the direction. The direction switching plate 41 is raised and lowered by a combination of a solenoid (not shown) and a coil spring.

  Next, the operation of selecting the cucumber C with the fruit sorter 1 configured as described above will be described (see FIGS. 1 to 4). First, in the zone P, an operator places the cucumber C on the delivery belt 13 (green) of the first conveyor 10 in operation. At this time, the black mark B displayed on the surface of the delivery belt 13 is used as a guide for placement, and the cucumber C is placed so that the major axis is in the transport direction J. Since the width of the delivery belt 13 is smaller than 1/3 of the length of the cucumber C, the cucumber C is placed on the three delivery belts 13 in this example. Cucumber C is conveyed in the direction of arrow J and reaches position detecting means 11. Here, light is irradiated from above the first conveyor 10. Then, the three delivery belts 13 on which the cucumber C is placed are specified by a dedicated camera. This information is transmitted to a control means (not shown).

  Since the mark W applied on the green belt 22 is white, the difference in brightness from the green background color is large, and the camera can reliably recognize the mark W. Next, the size of the cucumber C is photographed by a dedicated camera provided in the grade measuring means 12 and sent to the control means. The control means specifies the grade (large, medium, small) of the size of the cucumber C. Then, it is combined with the position information, and data indicating what size cucumber C is placed on which delivery belt 13 is created. Based on this data, the control means transmits an operation instruction to the first conveyor 10 and the second conveyor 14.

  Next, the movement of the cucumber C will be described in the case where the cucumber C is determined to be a medium size and the cucumber C is placed on the conveyor belts 13A, 13B, 13C. This operation will be described with reference to FIGS. 5A to 5C in addition to FIGS. In addition, the front part of the cucumber C is referred to as G1, the intermediate part is referred to as G2, and the rear part is referred to as G3.

  When the delivery belt 13A on which the front portion G1 of the cucumber C is placed approaches the second conveyor 14B, the direction switching plate 41 of the delivery mechanism provided immediately before the second conveyor 14B rises. When the delivery belt 13A reaches the delivery mechanism, the guide rod 31 of the delivery belt 13A comes into contact with the direction switching plate 41 and is guided in the direction of arrow a. Then, the motive power is further transmitted to the auxiliary belt 42 from the side, and further proceeds in the direction a. When the guide bar 31 moves the lower side of the belt 22 in the direction away from the second conveyor 14B, the upper side of the belt 22 moves toward the second conveyor 14B, thereby operating the delivery belt 13A. The front portion G1 of the cucumber C is sent out to the feed roller unit 23 (FIG. 5A). At this time, since the delivery belts 13B and 13C on which the intermediate part G2 and the rear part G3 of the cucumber C are placed are not operated, the cucumber C rotates slightly clockwise in the drawing around the front part G1.

  Soon after the delivery belt 13A starts to operate, the delivery belt 13B on which the intermediate portion G2 of the cucumber C is placed approaches the delivery mechanism, and the guide rod 31 of the delivery belt 13B comes into contact with the direction switching plate 41 and moves in the direction of arrow a. Led to. As a result, the feeding belt 13 </ b> B is operated to feed the intermediate portion G <b> 2 of the cucumber C to the feeding roller unit 23. Shortly thereafter, the delivery belt 13C on which the rear portion G3 of the cucumber C is placed approaches the delivery mechanism, and the guide rod 31 of the delivery belt 13C comes into contact with the direction switching plate 41 and is guided in the direction of arrow a. As a result, the feeding belt 13C is operated to feed the rear portion G3 of the cucumber C to the feeding roller unit 23 (FIG. 5B). The operation of the delivery belts 13B and 13C coming into contact with the direction switching plate 41 and delivering the cucumber C to the delivery roller unit 23 is the same as that of the delivery belt 13A, and thus the description thereof is omitted.

  At this time, the front portion G1 of the cucumber C reaches the delivery roller unit 23 and has been transferred onto the two rows of rollers 23b on the first conveyor 10 side, and the rollers 23b are directed toward the second conveyor 14B (see FIG. Operates to transport cucumber C). On the other hand, the intermediate part G2 and the rear part G3 of the cucumber C are placed on the delivery belts 13B and 13C, respectively, and while being conveyed in the conveyance direction (rightward in the drawing) of the first conveyor 10, 13C operates to send out toward the second conveyor 14B (downward in the figure).

  Therefore, the movement direction is different between the front part G1 of the cucumber C, the intermediate part G2 and the rear part G3. That is, the front part G1 of the cucumber C has only a motion component toward the second conveyor 14B and does not have a motion component in the transport direction of the first conveyor 10. On the other hand, the middle part G2 and the rear part G3 of the cucumber C have a motion component in the transport direction of the first conveyor 10 in addition to the motion component toward the second conveyor 14B.

  Since the front part G1, the intermediate part G2, and the rear part G3 are parts of the same cucumber C and are integrally formed, the two different operations cause distortion in the movement direction of the entire cucumber C. Here, as described above, since the belt 22 is made of a material having a high frictional resistance, the cucumber C hardly slides on the belt 22. On the other hand, a constant gap is formed at the right end of the roller 23b due to the repulsive force between the magnets M1 and M2, and the front part G1 of the cucumber C is in a direction (rightward) to reduce the distance. The distortion in the movement direction is eliminated by moving the roller 23b. In other words, the roller 23b on which the front portion G1 of the cucumber C is placed moves in the transport direction of the first conveyor 10 to absorb (cancele) the motion component in this direction. At the same time, the front portion G1 of the cucumber C is conveyed toward the second conveyor 14B by the rotation of the roller 23b. In this way, the cucumber C rotates clockwise in the drawing while canceling the motion component in the transport direction J by the delivery roller unit 23, and passes from the front G1 to the second conveyor 14B via the delivery roller unit 23. Change (Fig. 5 (c)).

  Of the two second conveyors 14B, the downstream side is intermittently operated. The operation timing is based on a command from the control means. Further, the operation time of the second conveyor 14B on the downstream side is from when the front part G1 of the cucumber C is transferred to when the rear part G3 of the cucumber C is transferred, and then the operation is stopped again.

  Thus, when the cucumber C is transferred between two orthogonal conveyors (the first conveyor 10 and the second conveyor 14B), the longitudinal direction of the cucumber C is conveyed in the conveying direction of the two conveyors. can do.

  At this time, since the delivery conveyors 13B and 13C are each provided with a protrusion 15, even if the cucumber C moves against the delivery direction, the cucumber C is pushed from the rear and is surely directed toward the delivery roller unit 23. C can be sent out.

  In the above-described example, the first conveyor (first transport body) is configured in a straight line. However, the present invention is not limited to this, and may be configured in a U-shape or an L-shape, for example. May be configured. In the above example, one protrusion is provided at the approximate center of the delivery belt. However, the present invention is not limited to this, and the protrusion is provided on the side opposite to the side on which the object is placed. May be. Further, two or more protrusions 15 may be provided instead of one.

  Further, in the above-described example, the permanent magnet M2 is provided at the end of the roller 23b and the permanent magnet M1 fixed at the end of the support shaft 23a is opposed to the permanent magnet M1. Instead, the magnetic force may be changed as necessary by changing the current using an electromagnet. Further, instead of the magnets M1 and M2, a constant space may be formed at the end of the roller 23b using a coil spring. In this case, the support shaft 23a is rotatably inserted into the center of the coil spring. Moreover, although the 2nd conveyor 14 was provided in the substantially right angle direction with respect to the 1st conveyor 10, it is not limited to this, You may provide in diagonally forward or in parallel with the 1st conveyor 10. FIG.

  Furthermore, in the above-described example, the visibility of the mark is improved by setting the color of the belt 22 to green and the mark W formed thereon to white, but the present invention is not limited to this color combination. As long as it is a combination of colors that can improve the visibility of the mark, any combination may be used. At this time, visibility can be further improved by combining colors so as to increase the brightness difference.

  As shown in FIG. 6, a delivery belt 113 may be configured. That is, a plurality of small protrusions 115 are formed on the surface of the belt 112 to support the cucumber C from below. The small protrusion 115 is preferably made of a flexible material such as rubber. The other members are the same as in the example of FIG.

  In the above example, a cucumber having a large difference between the major axis and the minor axis is used as an example of the object. However, the present invention is not limited to this, and for example, a crop with a small aspect ratio such as a tomato. It may be.

  Note that the object sorting apparatus of the present invention is not limited to sorting crops (objects) such as cucumbers and tomatoes. For example, the quality and size of the flowers collected by cutting and harvesting florets are bundled. The present invention may be used for classification of various objects, such as classification of industrial products such as candles according to size and quality. This is particularly effective when conveying an object having a large aspect ratio.
