EXAMPLE An example of the present invention will be described. The figure shows a fruit weight sorting device, which is used for pears, for example. The sorting line mainly includes a cargo receiving section 1 for receiving fruit containers from farmers, a grade sorting section 2 by a grade evaluator, a weight-based class sorting section 3, classifying and extracting sections 4, 4.

Of these, the load receiving section 1 has load receiving conveyors 5 and 5 in the form of roller conveyors, and the conveyors 5 and 5 are taken out in parallel with the grade evaluation conveyor 6 having a proper number of threads. , 7 are branched and connected. Grade selection section 3
The grade evaluation conveyor 6 has a belt conveyor form and is provided in seven rows in the illustrated example, and the predetermined number of rows is classified into excellent, excellent, and good, and is connected to the selection conveyor 8 in the subsequent class selection section 3. is there. Reference numeral 9 is a conveyor for collecting empty containers.

In many cases, the grade evaluation conveyor 6 and the selection conveyor 8 are constructed in a series, and these are pulled by the selection cup portions 9, 9 ... On which fruits are placed and the endless chain at predetermined intervals to support the cups. , And the selection cup portions 9, 9 ... Can maintain a horizontal posture by the sliding contact support of the guide rails not shown in the figure, and the absence of the rails causes the selection cup portions 9, 9 ... It can be discharged by.

Reference numeral 11 is a weight detector provided for each line. This weight detection data is sent to the control unit 12. In the control unit 12, the detection data is compared with the preset class data, and the class of this fruit, for example, 4
While determining which of L, 3L, 2L, L, M, S, and 2S it belongs to, the rail control signal for overturning the selection cup unit 9 by outputting the rail at the designated grade / class designated position is absent is output. This is a possible configuration.

As for the grades in the sorting conveyor 8, for example, as shown in the figure, the outermost two of the seven and the inner two are 4 in total, which is the excellent grade, and the inner 2 are the superior grades. The inner strip is set to a good grade. Only one of the innermost strips is supported by the cup so that it can be discharged on both the left and right sides, and the overall length is shortened. Fruit stock tables 13, 13 ... Are arranged in the sorting and taking-out sections 4 and 4 of the sorting conveyor 8 for each grade. A cardboard box a is provided at each end of the table 13 so as to be lifted and lowered by a column 14 and to be moved up and down by an expansion and contraction operation of an air cylinder mechanism 15.
An elevating frame 16 is provided. The elevating frame 16 has a structure in which a roller 17 is disposed in the horizontal portion of the L-shaped frame portion to receive a corrugated cardboard box.
The heights of the rollers are set to be substantially the same, and when the rollers 17 are lowered, the rollers 17 can be fitted into the roller portion of the relay roller conveyor 18 for feeding the products, which is disposed near the lower side, so as to be flush with the roller portion. The end of the relay roller conveyor 18 is connected to the product conveyor 19. The product conveyor 19 is arranged in parallel with the sorting conveyor 8 and is configured to be able to receive and transfer the corrugated cardboard boxes from the respective classification and extraction sections 4. Reference numeral 20 is a partitioning material to be inserted between the multi-stage fruits in the cardboard box.

Regarding the supply of empty cardboard boxes, a box making machine 21 is provided on the mezzanine floor, and the box making machine 21 is constructed so that a plurality of cardboard boxes having different heights can be formed. The corrugated cardboard boxes have different inclined guide chutes 22a, 22b, 22c and distribution conveyors 23 for each different size from the mezzanine floor
a, 23b, and 23c are provided so that they can be independently supplied to the classifying and extracting units 4, 4, ....

That is, the box distribution conveyors 23 are provided in a plurality of upper and lower stages, and the corrugated box a having the lowest height is arranged on the upper box distribution conveyor 23a, and the middle box distribution conveyors 23b,
The lower level conveyor 23c has a standard height cardboard box b,
In order to be able to supply the high corrugated cardboard boxes c respectively, it is provided corresponding to the inclined guide chute 22. Each of the distribution conveyors 23 has a configuration in which belt conveyors 24, 24 ... Of driving type are arranged at appropriate intervals, and free rollers 25, 25 ... Are arranged between them. Two
6 and 26 are provided at appropriate intervals and overhang support portions 27 and 2 are provided.
It is a pillar that holds 7 ...

The upper, middle and lower box distribution conveyors 23a, 23a
The center lines Ca, Cb, C of the transfer parts b, 23c
The rollers 25, 25, ... Are arranged on the overhanging support portions 27, 27, .. The lower box distribution conveyor is closer to the fruit stock tables 13, 13 ... With respect to the upper box distribution conveyor 23a.
Further, guide walls 28 are provided on the left and right sides of the distribution conveyor 23 in the transfer direction, but the guide wall 28a on the side facing the stock table 13 is set low to facilitate the taking out.

The operation of the above example will be described. The container carried from the farmer is transferred by the cargo receiving conveyors 5 and 5 and the take-out conveyors 7 and 7 of the cargo receiving unit 1. The grade evaluator puts out one fruit from the container and evaluates the grade according to its appearance, etc., and places it on the selection cup parts 9, 9 ... Corresponding to a predetermined grade. The weight of the fruit on the conveyor 6 is detected by the weight measuring device 11 for each cup, and the detection signal is input to the control unit 12. The control unit 12 determines which class the fruit belongs to, and when the fruit reaches the classifying and extracting units 4 and 4 of a predetermined grade and class, the rails outside the drawing are operated to eject the fruit by overturning.

The fruits stay on the fruit stock table 13 and are packed by a packing worker. At this time, it is known in advance which size of the empty cardboard box is to be selected, and the worker selects the predetermined box size from the various types of boxes supplied by the multi-stage distribution conveyor 23. take out,
It is placed on the elevating frame 16 and stands by. The elevating frame 16 is made to stand by ascending and the boxing work is continued, but when the boxing of the first stage is completed, the partitioning material 20 is added to enable the second stage supply.

When the packaging of one box is completed in this way, the elevating frame 16 is lowered, transferred to the surface of the relay roller conveyor 18, transferred, and transferred to the product conveyor 19. When the cardboard box becomes full on the way, the corresponding box is taken out from the box distribution conveyor 23 to deal with it. At this time, since the center lines Ca, Cb, Cc of the respective transfer parts are displaced, it is easy to take out.

Moreover, since the guide wall has a low take-out side, there is no possibility of dropping off in the middle.
