The figure is a plan view of the sorting device, FIG. 4 is a side view, and FIG. 5 is a perspective view of the embodiment with the movable conveyor 3 retracted.

This will be explained starting from the overall configuration shown in FIG.

The harvested selected fruits are piled up in the receiving section 13. and container feeding flat conveyor 12
Then, the container is sent to the container feeding free rollers 14.

Here, the workers line up and place them on the conveyor for the washer 16. 15 is an empty container feeding conveyor, from which the empty container returns to the conveyor 11.

The selected fruit from which dirt and pesticides have been washed off by the washer 16 passes through a dryer 17 on a conveyor that performs natural drying or dehumidifying drying. Thereafter, defective items are sorted out by a worker on the manual sorting conveyor 18. Next, the selected fruit passes through a sorting sensor 19,
They are sorted and identified by shape or weight, and a label is attached by the labeler 20.

Next, while flowing through the fixed conveyor 1 at a constant speed, the receiving boxes 32, 3 are sorted by the sorting device of the present invention based on the signal identified by the sorting sensor 19.
Fallen in one of 2.

The receiving boxes 32 are divided into five groups: the first five are grade A, the next five are grade B, and the next five are grade C. The selected fruits separated in the receiving box 32 are packed into empty boxes by an operator on a boxing table 33. At this time, in the case of pears and apples, a capping device is used to cover the fruit with a cover that protects the outer skin. 21 is a totalizer that measures the passage of selected fruits.

After the boxes are packed, they are placed on 24 product feed conveyors and sent from a product feed curve conveyor 30 to a conveyor 31. Thereafter, the lid is sealed by the packaging machine 29 and placed on the product shipping section 28. Empty boxes are made by an automatic box making machine 27 for lower boxes, and sent to an empty box carrier 23 from an empty box sending chute 26 . Reference numeral 25 is an automatic box making machine for upper lids, which produces upper lids.

In the case of FIG. 2, the structure is such that a larger amount of selected fruits can be sorted and packaged quickly and with fewer workers. Reference numeral 36 denotes a container damper, into which the selected fruits are placed, and the potatoes, etc. are then sent to a bead removal roller conveyor 35 while being removed by a brush conveyor 40. Here, extremely small balls pass under the roller conveyor. Reference numeral 38 denotes a two-divided feeder that divides the material into two directions, and the material is sent to two manual sorting conveyors 18, where it is sorted by an operator.

Next, the dispersion feeder 34 disperses it to 12 alignment feeders 37, 37, . . . . After being aligned in an alignment feeder 37, the particles pass through a sorting sensor 19 and are sorted.

After that, it is placed on the fixed conveyor 1 and reaches the movable conveyor 3 interposed in the middle, and this movable conveyor 3
As the fruit retreats, the selected fruit falls downward,
This leads to take-out conveyors 2, 2... The products are delivered from the take-out conveyor onto the boxing table 33 and packed into boxes.

26' is an empty box conveyor, and 27 is an automatic box making machine for lower boxes. In addition, 24 is a product feeding conveyor, 2
9 is a packing machine.

The present invention relates to a device for distributing items from the fixed conveyor 1 to the take-out conveyor 2 or the receiving box 32 in such an overall configuration.

3, 4, and 5, in the embodiment, the conveyance speed of the movable conveyors 3, 3a, 3b is the same as that of the fixed conveyors 1, 1a, 1b, 1c, and the height of the conveyance surface is also the same as that of the fixed conveyors. It is assumed that the height is the same as that of 1.

Furthermore, the movable conveyors 3a and 3b are pushed and pulled by movable cylinders 4a and 4b to be retracted in parallel. The movable conveyor 3 is driven by two spline shafts 5, 5 arranged in parallel;
When the movable cylinder 4 is extended or contracted, the movable conveyor 3 is moved to the spline shafts 5, 5.
It is configured to slide between the pulleys 6 and 6 to form a drop opening.

a drive pulley 6 for driving the movable conveyor 3;
6 is a drive pulley 7 that drives the fixed conveyor 1
The drive pulley 6 is configured to have a smaller diameter than the drive pulley 7, so that the drive pulley 6 can be arranged above the drive pulley 7 in an overlapping manner.

A1 and A2 are selected fruits, which have already been sorted and identified by the sorting sensor.

The selected fruits on the fixed conveyors 1a, 1b, 1c are sorted and stored in a computer for identification, and the fruits on the fixed conveyors 1a, 1b, 1c are transferred to the movable conveyors 3a, 3b according to the class.
When this is reached, a command signal is issued from the computer and the movable conveyors 3a, 3b are evacuated. When the movable conveyors 3a, 3b retreat, the selected fruits on the fixed conveyors 1a, 1b fall onto the take-out conveyors 2, 2a, 2b.

The conveyance speed of the movable conveyors 3a, 3b is assumed to be the same as the conveyance speed of the fixed conveyors 1a, 1b, 1c.

(c) Effects of the Invention Since the present invention is configured as described above, it has the following effects.

First, since the movable conveyor can be retracted by sliding in the direction perpendicular to the conveyance direction relative to the fixed conveyor, it is possible to evacuate the movable conveyor by rotating the movable conveyor up and down. This eliminates the need to open up a large margin and allows the joints of both conveyors to be brought as close together as possible.

Second, by making the diameter of the driving pulley of the movable conveyor smaller than the diameter of the sliding pulley of the fixed conveyor, at the joint between both conveyors,
In addition to bringing the tips of the conveyors as close as possible, it is possible to overlap the top and bottom of the conveyors, and unlike conventional conveyors, the conveyance of selected fruits becomes stagnant in the recesses and steps between the two conveyors, and the conveyance speed changes. In addition, it is possible to suppress the occurrence of problems in which the set time from the position of the sorting sensor to the position of the movable conveyor and the actual conveyance time deviate and the selected fruits do not fall.
