Description

  The present invention relates to an automatic sorting method and an automatic sorting apparatus for sorting various fruits and vegetables by size, shape, color, sugar content, etc., such as tomato, apple, peach, It is suitable for the selection of fruit vegetables such as pears, eggplants, melons, and Kodama Nishimaki.

Fruit vegetable sorting method that transports fruit vegetables, discriminates the equal class etc. of fruit vegetables with a fruit vegetable identification device installed at a predetermined position during the conveyance of the fruit vegetables, and sends the fruit vegetables to the conveyance direction side (fruit vegetable discharge side) based on the result There are various kinds of fruit and vegetable sorters.
There is a fruit and vegetable sorting device in which fruit and vegetables are carried on a fruit and vegetables carry and are sent to a fruit and vegetable receptacle when they are conveyed to a predetermined position. In this case, a backrest (for example, a backrest having a mortar-like surface) for stabilizing the fruit vegetables on the fruit vegetables carry is provided only on the back side that is not the fruit vegetable discharge side. This is because if a backrest or the like is provided on the fruit vegetable discharge side of the fruit vegetable carry, this backrest becomes an obstacle when the fruit vegetables are fed into the fruit vegetable receptacle.

  However, if the backrest is only on one side, fruit vegetables are rapidly put on the fruit carrier on the traveling fruit carrier, so that the fruit can not be placed in the prescribed posture and it may fall to the near side or in a prescribed posture. Even if the fruits and vegetables were put on, the fruits and vegetables could fall down in the middle of the transportation, or the fruits and vegetables could be shifted from the placed position. Such a situation arises because there is support only on one side.

  If the fruit and vegetables are fallen on the fruit and vegetable carrier, the sugar content and ripeness value of the fruit and vegetables will be distorted in the case of the fruit and vegetable identification device using a light sensor (sugar meter). If the fruit vegetables fall down, they will appear larger than they actually are, and the shape will also look different. Also in the color discrimination, when the color viewed from directly above is used as a reference, the fallen fruit vegetables will see the side surface, and the measurement value will be distorted.

  It has been a problem in the industry to find a means for stabilizing the placement position of fruit vegetables when the fruit vegetables are discriminated by the fruit vegetable discrimination device and then smoothly feeding the fruit vegetables to the side in the transport direction. In order to solve this problem, the applicant of the present application has previously applied for patents on various fruit vegetable sorting apparatuses (Patent Document 1). In this Patent Document 1, it is proposed that a part on which fruit vegetables are placed is set in advance, and the fruit vegetables are conveyed in a line in the conveying direction, and an example where the fruit vegetables are placed in a mortar shape is presented as an example. ing.

Japanese Patent Application Laid-Open No. 2004-99285.

In this case, as shown in FIG. 1, the place where the worker who places the fruit and vegetables is placed and the place where the fruit and vegetables are sent out after selection are on the same side with respect to the fruit and vegetable transport body in order to reduce the space for arranging the fruit and vegetable distinguishing device. There were many cases. As a result, the input button is attached to the opposite side (FIG. 7) from the place where the worker who places the fruit vegetables is placed, and there is a problem that it is difficult to press the input button.

  Since the position where fruit vegetables are placed is shown in Patent Document 1, the position where fruit vegetables are placed is stabilized immediately after the fruit vegetables are placed and arranged in a line in the transport direction. However, it cannot be said that the fruit vegetables are firmly fixed in the mortar-shaped dent, and the fruit vegetables may be inclined or slightly moved by vibration or the like while being conveyed for a while after the fruit vegetables are placed. As a result, when discriminating with the fruit vegetable discriminating apparatus, the placement position of the fruit vegetables is not constant (FIG. 8), which hinders accurate discrimination.

(Embodiment 1)
1st Embodiment of the fruit vegetable automatic selection apparatus and fruit vegetable automatic selection method of this invention is described based on figures. FIG. 1 is an overall plan view of an automatic fruit vegetable sorting apparatus according to the present invention. The strip-shaped continuous body shown in the figure is a fruit and vegetable transport body 2 that transports the fruit and vegetable 1 in the direction of arrow a (from left to right in the figure). Is disposed in the middle of the conveyance of the fruit vegetable carrier 2, and a fruit vegetable identification device 4 for identifying the class, such as the size, shape, color and sugar content, of the fruit vegetable 1 being conveyed is disposed. On the end point side (right side in the figure) from the position where 4 is arranged, fruit vegetable receivers 5 for sorting the fruit vegetables 1 by class are arranged.

  In addition, the space where the worker who places the fruit vegetables 1 in the supply unit 3 is arranged is required to have an appropriate size such as a work space and a space where the fruit vegetables 1 before being placed on the fruit vegetable carrier 2 are placed. On the other hand, the fruit vegetable receptacle 5 also requires a predetermined space as shown in the figure. Therefore, usually, the space in which the worker is arranged in the supply unit 3 and the fruit vegetable receiver 5 are often arranged on the same side with respect to the fruit vegetable carrier 2 (right side in the drawing in the conveyance direction a). By arranging in this way, the space on which the operator is placed and the side opposite to the side on which the fruit vegetable receiving body 5 is placed (left side with respect to the transport direction a in the figure) can be a wall surface. It is possible to make effective use of the factory space.

The fruit and vegetable carrier 2 is formed by attaching a large number of fruit and vegetable carriers 8 in the conveying direction (arrow a direction) to an endless traveling body 7 that is an endless chain installed on the drive sprocket 6a and the driven sprocket 6b. The drive sprocket 6a is rotated by the power of the motor M, and the endless traveling body 7 travels in the direction of the arrow a along with this rotation, and the vegetable carrier 8 is conveyed.
In FIG. 1, the fruit and vegetable carrier 2 circulates in a straight section. However, the present invention is not limited to this, and it can be circulated in a plane.

  The fruit vegetable carrier 8 is equipped with a fixed support 9 (FIG. 2) on which the fruit vegetable 1 can be poured in order to convey the loaded fruit vegetable 1 in a stable state. The fruit vegetable carrier 8 has a function for sending out the loaded fruit vegetable 1 when it is conveyed to the fruit vegetable receptacle 5, so that the fixed support 9 is provided on the opposite side of the fruit vegetable carrier 8 from the fruit vegetable 1 sending side. Is done. That is, in FIG. 1, the fixed support 9 is provided on the left side (upper side in the drawing) of the fruit carrier 8, so that it does not become an obstacle when the fruit carrier 8 sends out the fruit 1 to the fruit receiver 5. It becomes an auxiliary tool for extruding 1.

In addition, as a means by which the fruit and vegetable carrier 8 sends out the fruit and vegetable 1 to the fruit and vegetable receiver 5, the fruit and vegetable carrier 8 is a belt conveyor type, and the belt crosses the running direction (arrow a direction) of the fruit and vegetable carrier 2. Then, it may be rotated in the direction toward the fruit vegetable receptacle 5 (from the top to the bottom in FIG. 1). However, in this case, since the fixed support 9 is mounted on the belt (that is, the fixed support 9 moves together with the belt), a belt conveyor that can reciprocate is used rather than a belt conveyor that circulates and rotates. It is desirable.
The belt conveyor is not limited to being rotated in a direction orthogonal to the traveling direction of the fruit and vegetable transport body 2, but may be a front diagonal direction or a rear diagonal direction. In addition, it is not limited to a belt conveyor but a roller conveyor, the vegetable carrier 8 is moved without moving the fixed support 9, the fruit vegetable 1 is sent out, the fruit carrier 1 is tilted and the fruit vegetable 1 is rolled and moved. Can be used.

  As shown in FIG. 1, apart from the endless traveling body 7 of the fruit and vegetable transport body 2, a fruit and vegetable support 10 that runs in parallel therewith is provided. The fruit vegetable support 10 is provided with a support tool traveling body 11 and a large number of movable supports 12 provided in the traveling direction. The support tool traveling body 11 is circulated while being substantially parallel (including parallel) to the endless traveling body 7 of the fruit and vegetable transport body 2.

  As shown in FIG. 2, the movable support 12 forms a fruit vegetable placement portion 13 that clearly indicates a position on which the fruit vegetables 1 are placed together with the fixed support 9 on the fruit carrier 8. The fruit vegetable placement unit 13 indicates a position where the fruit vegetable 1 is to be placed on the operator, and stabilizes the position of the fruit vegetable 1 during transportation (does not move from that position). 13 is provided with a function of stabilizing the mounting posture of the fruit vegetables 1 placed on (not tilting after mounting).

  Since the movable support 12 forms the fruit vegetable placement portion 13, the interval at which the fruit carrier 8 is provided in the transport direction and the interval at which the movable support 12 is provided in the traveling direction are substantially equal intervals (including equal intervals). The transport speed of the fruit vegetable carrier 8 and the traveling speed of the movable support 12 are also substantially constant (including constant speed).

  As shown in FIG. 2, the movable support 12 and the fixed support 9 are arranged so as to sandwich the fruit vegetables at both ends of the fruit carrier 8. That is, since the fixed support 9 is provided on the side opposite to the side where the fruit vegetables 1 are sent to the fruit receiver 5, the movable support 12 is arranged on the side where the fixed support 9 sends the fruit vegetables 1 to the fruit receiver 5. Is done. The support tool traveling body 11 is also arranged on the same side (the lower side of the fruit and vegetable transport body 2 in FIG. 1).

  The movable support 12 becomes an obstacle when the fruit vegetable 1 is sent to the fruit vegetable receptacle 5, but is necessary for the operator 3 to form the fruit vegetable placement part 13 in the supply part 3 where the fruit vegetable 1 is placed on the fruit vegetable carrier 8. Yes, it is necessary for accurate determination by the fruit vegetable discriminating device 4 in a state in which the fruit vegetable mounting unit 13 stabilizes the fruit vegetable 1 at a predetermined position. Therefore, the installation position of the fruit vegetable discriminating device 4 and the installation position of the fruit vegetable receptacle 5 are set with the support tool traveling body 11 as a starting point (the left end in FIG. 1) from the front side of the supply unit 3 (before the running direction of the fruit vegetable transport body 2). The movable support 12 is placed on the fruit vegetable carrier 8 while traveling in the section whose end point is between the two and the fruit vegetable carrier 2 (while the fruit vegetable carrier 2 is traveling). A mechanism for removing the movable support 12 from the fruit carrier 8 when it appears and forms the fruit and vegetables mounting portion 13 and travels in the section where the fruit and vegetable receiver 5 is disposed. Note that the motor, drive sprocket, and driven sprocket of the support tool traveling body 11 may be different from the fruit vegetable carrier 2, or the fruit vegetable carrier 2 as shown in FIG. Also good.

  As shown in FIG. 2, the movable support 12 is connected to the support traveling body 11, and the movable support 12 protrudes from the support traveling body 11 in order to form the fruit vegetable placement portion 13 on the fruit vegetable carrier 8. It is in a state of projecting to the side in the running direction. Thus, the movable support 12 may be wound around the drive sprocket (driven sprocket) of the support traveling body 11 with the movable support 12 protruding from the support traveling body 11, but in this case, the mechanism of the drive sprocket (driven sprocket) Becomes complicated and large.

  In order to avoid such a mechanism, as shown in FIG. 3, the movable support 12 may be moved toward the support traveling body 11 to reduce the overall width and then be wound around the drive sprocket (driven sprocket). it can. As shown in FIG. 2, a part of the movable support 12 is pin-coupled to the support traveling body 11 at a connection point 14 so that the movable support 12 can rotate with respect to the support traveling body 11. The structure is configured to be able to rotate and move above (or below) the body 11. As shown in FIG. 3, the movable support 12 with the rotation mechanism projects over the vegetable carrier 8 by the overhanging guide body 15 to form the fruit vegetable mounting portion 13, and the support guide traveling body 11 with the storage guide body 16. The movement width is reduced by being placed toward the.

  Specifically, when the movable support 12 stored in the direction of the support tool traveling body 11 travels, a part of the movable support tool 12 comes into contact with the overhanging guide body 15 and further travels, the overhang guide body 15. It gradually protrudes onto the fruit vegetable carrier 8 while being pushed by and rotated. A part of the movable support 12 that has passed through the fruit vegetable discriminating device 4 together with the fruit vegetable carrier 8 comes into contact with the tension storage guide body 16 and gradually rotates while being guided so as to be guided by the storage guide body 16 as it travels further. It is stored in the direction of the support tool traveling body 11.

  In the supply unit 3, the operator places the fruit vegetables 1 on the fruit vegetable placement part 13 formed by the fixed support 9 and the movable support 12 on the fruit carrier 8. Since the position where the fruit vegetables 1 should be placed is clearly shown by the fruit vegetables placing section 13, the operator can easily work. Note that the placement work may be performed by a device or work robot on which the fruit vegetables 1 are placed, regardless of the operator.

  The fruit and vegetable 1 conveyed to the fruit and vegetable determination device 4 can be determined stably and an accurate determination result can be obtained because the mounting position and mounting posture of the fruit and vegetable 1 are fixed by the fruit and vegetable mounting unit 13. Can be output.

  The fruit vegetable 1 that has been transported to the fruit vegetable receiver 5 is sent to the fruit vegetable receiver 5 that is determined in advance based on the determination result of the fruit vegetable determination device 4. By using this fruit vegetable receiver 5 as a belt conveyor, when the fruit vegetable 1 is fed, the belt conveyor of the fruit vegetable receiver 5 moves by one fruit vegetable to make a space for placing the next fruit vegetable 1 thereon. Alternatively, just before the fruit vegetable 1 is fed, the belt conveyor of the fruit vegetable receiver 5 moves by one fruit vegetable to make a space for placing the fruit vegetable 1 on it. By repeating this, fruit vegetables 1 of a predetermined standard are sequentially sent to the fruit vegetable receiver 5 according to the determination result, and the fruit vegetables 1 are pooled on the belt conveyor of the fruit vegetable receiver 5.
