Abstract

PURPOSE:To sort class and grade with higher reliability by reducing the missing of a flaw by judging and sorting the surface color, back color, flaw or grade of fruit by the cameras provided before and behind a reversal transfer apparatus. CONSTITUTION:Both front and back surfaces of fruit are detected by cameras 17a, 17b before and behind fruit holding transfer devices 15 and the sorting discharge signals outputted from the respective cameras pass through a pre- processing part 47 to enter a set controller 48 and the fruit is judged on the basis of superior, excellent and fine grades by a sorting and judging part 49 to be successively transferred to the drawing-out conveyor set by a gate control part 50. Therefore, fruits same in class and grade are taken out to each discharge port of an encasing part 18 to be automatically subjected to encasing treatment. The fruit holding transfer apparatus 15 is reversed up and down when it delivers fruit from a supply conveyor 1 to a cup conveyor 2 and, since two sensor cameras 17a, 17b are used, the front and back classes and grades of fruit can be sorted and confirmed and high order class and grade sorting becomes possible with high reliability.

Explain the seven effects.

Fruits such as pears, which are harvested with the hangers intact, are placed on the individual supply conveyor 1.1. In the supply conveyor li, the fruit stems are held down under the action of the fruit holding device 4 while being pulled down by the pulling device 7. Thereafter, the tip of the fruit stalk and the bag are cut off as it passes through the 8 disk blades, and is further transported to the rear. The Nilabari J cutting section 10 cuts the stem part even shorter. The paper bag is Fufu Nosuru 13,13
When it is exposed to the action, it opens and floats, and the left and right clamping bodies 11.11 act on the fruit or paper bag to remove the bag by pinching the bag and squeezing it up.

The unbagged fruit is transferred from the end of the supply conveyor 1# to a holding and transferring device 15 that turns over the fruit.

(Cenograph 24 set at approximately the same level as It feeding conveyor 1)
．． 24, the fruit holder 25.25 moves to the left and right of the unbagged fruit on the supply conveyor 11,1 (61, fiQt and accompanies it. At the top of the supply conveyor), the first spring 4↓
, 4↓The fruit holding body 25°25 which is in the expanded state due to the action,
Support body 30, rail 42, 42 due to transition to Cheno 24,
30 is in contact with the conveyor and pinches the unbagged fruit on the side. The movement of the cheno 24 causes the rollers 39 to ride on the guy I-rail 38 and separate the clamped fruit from the conveyor I.

The fruit holding body 25 moves backward together with the cup conveyor 24 and moves toward the starting end of the cup conveyor 22, but during this process, it reaches a predetermined position. There is a lug 37 at t, and the carrier 36 at the end of the rotating shaft 27 meshes with this lug. Therefore, the same rotating shaft 27. gear 3
5. The fruit holder 25°25 is 180° to the tool through 34.
At the same time, the fruit is flipped from a state where the stem is facing downwards to a state where the stem is facing upwards. The fruit that has moved to the starting end side of the cup conveyor 22 after being reversed is transferred to the roller 39 from the guide rail 38.
When the cup falls off and the support body 30 is released from the rail 42, it is released and dropped onto a predetermined cup surface.

Holding and transferring device i! Before and after f, 1.5, the front and back screens are detected by the camera kings 7a and 17b, and the sorting and discharge signals output from each camera pass through the preprocessing section 47 and enter the setting controller I-roller 48. The classification determination section 49 judges the materials as excellent, excellent, and good, and the gate control section 50 sequentially transfers them to the drawer conveyor 4-5.45 set to a predetermined grade. Therefore, fruits of the same grade and grade are taken out from each outlet of the boxing section 18'8, and are automatically boxed.

In addition, on the transfer starting end side by this conveyor 22, a stem cutting correction section 4-4. , 4.4, the workers waiting on standby judge the cutting status of each fruit's stem, and if it is insufficient, it is corrected and cut with nippers.

As mentioned above, the fruit holding and transferring device 15 is connected to the feeding container 1.
When the cup conveyor 22 takes over from the cup conveyor 22, the two sensor cameras 17a, ],
By using 7b, it is possible to check the front and back sides of equal class sorting, which is convenient for highly reliable and advanced equal class sorting.

The fruit holding and transferring device 15 has a form in which the fruit is held between the right and left sides with the fruit holding bodies 25, 25, but it may also be in a form in which the fruit holding body is held with an adsorbent and turned upside down.
The holding means may have other configurations. Further, the reversal rotation angle may be limited to 80° and may be arbitrarily set.
