The above-mentioned sorting device is provided with a stacked body in which a plurality of sorting plates are stacked horizontally, and each sorting plate has a plurality of sorting holes horizontally formed in which the inner diameter gradually increases from the lower to the upper sorting plate. During the horizontal movement of the stack, the fruit to be selected is supplied to the upper sorting hole of the stack, and the fruits are sequentially moved from the lower sorting plate during the horizontal movement of the stack to be located in the sorting hole of the sorting plate. If the device is provided to take out and sort selected fruits, the selected fruits can be reliably sorted well.

However, when feeding selected fruits to the above-mentioned stack, if they do not enter the sorting hole of the selected fruits but land on the surrounding flat area, they will not be sorted, and in this state, the stack will If the fruit falls into the sorting hole due to vibration during the transfer, there will be problems such as contamination of the selected fruit in other sorted grade positions.

Therefore, the object of this invention is to provide a sorting device for fruits, etc., which can solve the above-mentioned disadvantages.

According to this invention, it is possible to prevent selected fruits from being placed around the sorting holes at the top of the stack, and to reliably supply selected fruits to each sorting hole at the starting end of the horizontal transition of the stack. a rotary supply means for supplying the selected fruit to the sorting hole;
Between the stacked bodies, a plurality of partition rods are provided extending in the direction of transport of the stacked bodies to partition each sorting hole.

By providing the partition rod, the selected fruits fed one by one from the rotating supply means roll and transfer to the flat area around the sorting hole and the sorting holes on both sides, and two fruits enter at the same time, causing clogging. It is possible to control the fruits to be selected and guide them one by one to the corresponding sorting hole, allowing highly accurate sorting.

An embodiment of this invention having such characteristics will be described in detail below based on the drawings.

The drawing shows a citrus sorting device. In Figure 1 and Figure 2, a wide roller conveyor 2 is located in front of a chute 1 to which selected fruits are fed. Bars 4... are installed between the chains 3 and 3 provided, and rollers 5 are rotatably fitted around the outer periphery of each bar 4.

Further, the selected fruits scooped up by the arm 16.16 are held between the arm 16.16 at the front in the direction of rotation, and are fed to the lower sorting conveyor 12 by rotating as they are.

As a result, the rotary supply means 13 regulates the selected fruits one by one and supplies them to the sorting conveyor 12, and if the feeding timing is set in accordance with the later-described sorting holes of the sorting conveyor 12, the fruits will enter the sorting holes. The supply will be regulated as much as possible.

Between the rotary supply means 13 and the starting end of the upper horizontal transition portion of the sorting conveyor 12, a plurality of partition rods 19 are arranged between the sorting holes along the transfer direction of the sorting conveyor 12. These partition rods 19... restrict the selected fruits supplied by the rotating supply means 13 from rolling in the left-right direction.

The aforementioned rubber regulating plate 14 is made of a rubber material and is vertically installed on the front side of the aforementioned rotating supply means 13, and its lower end is close to the upper surface of the sorting conveyor 12 and acts to sweep this upper surface. The rubber regulating plate 14 is formed by being cut out in this manner so as to correspond to the grooves 7 of the vibrating conveyor 6 in the previous stage.

This rubber regulating plate 14 is connected to the arm 16 of the rotating supply means 13.
This surface prevents the selected fruit held by the sorting conveyor 16 from falling, and if the selected fruit fed to the sorting conveyor 12 does not enter the sorting hole but rides on the surrounding flat area, it is prevented from falling. It is regulated to be swept away and put into the sorting hole.

The aforementioned sorting conveyor 12 has a pair of left and right chains 20.2.
A large number of laminates 21 are installed between the holes.

The aforementioned chains 20 and 20 are provided with sprockets 43 on the left and right sides so as not to rotate along an oval path, and are driven by an appropriate drive source.
