Description

Detailed Description of the Invention: Expandable and contractible rubber holes are arranged in series in the moving direction, and a guide device is provided to sequentially enlarge the rubber holes from the starting end to the terminal end at the upper transition section of the conveyor, so that each rubber hole is the same. This relates to a fruit sorting machine that can be expanded and contracted steplessly in multiple radial directions on a plane, and has a guiding device that can adjust the diameter of the rubber holes carefully so as not to damage the fruit. The purpose is to sort fruit and apply it to fruits of different sizes.

To explain the embodiment of the present invention shown in the drawings, two endless chains 74, 4 are hung around the drive sprocket 6 and the driven sprocket 7 on the machine frame 1, and a plurality of base plates 5 are installed on both chains 4, 4. The conveyor 2 is formed by arranging these in series at equal intervals.

A through hole 5a is formed in the center f31 of the base plate 5, and a donut-shaped disk 8 is rotatably supported on the base plate 5 by an outer guide roller 9. As shown in FIG. 4, six arcuate guide slots 10 are drilled in the disc 8, intersecting the radial direction.
A sliding piece 12 that can freely slide in the radial direction is provided between the six radial guide guides 11 and 11 provided in the same plane between the circular plate 8 and the base plate 5. The protruding pins 13 are slidably fitted into the arc-shaped guide slots 10, respectively. Rubber (sponge may be used) is attached to the tip edge 12a of each sliding piece 12, and expandable and contractible rubber holes 3 are formed by the six tip edges 12a. A funnel-shaped guide plate 12b is provided on this tip edge 12a. A protrusion 14 is provided on this disc 8, and the protrusion 14 and the support shaft 9 of the guide roller 9 are connected to each other.
A is connected to the guide 1 by a spring 15, and the guide 1 is installed in the machine frame L.
6a guides and rotates the protrusion 14 from the solid line position in FIG. Accordingly, it is possible to provide a guide device 16 that enlarges the rubber hole 3 in four stages. In this way, each rubber hole 3 is formed by the tip edge 12a of each sliding piece 12 so that it can expand and contract steplessly in a plurality (three) of radial directions on the same plane. The guide device 16 is connected to a guide tube 23 fixed to the machine frame 1 as shown in FIG.
The sliding tube 24 is fitted into the guide tube 23, the guide guide position adjustment screw 20 is rotatably supported on the guide tube 23, and the same screw 20 is fitted on the sliding tube 24.
0, and by rotating the same screw 20 forward and backward, the sliding tube 24
is moved toward and away from the rubber hole 3 side, and the guide guide F 16 a provided on the sliding tube 24 is moved closer to the rubber hole 3 side (by adjusting the position of the projection 14 in contact with it). The inner diameter of the rubber hole 3 can be adjusted. In the figure, 17 indicates a fruit feeding roller, 18 indicates a fruit receiving plate, 19 indicates a feeding fruit lifting device, 20 indicates a set screw for the sliding tube 24 and the guide 16a, and 22 indicates the center portion of the expandable rubber hole 3. It is a push-up tool.

Therefore, by rotating the guide guide position adjusting screw 20 in the forward or reverse direction, the position of the guide guide 16a is adjusted and the rubber hole 3 is adjusted.
When the conveyor 2 is moved in the direction of the arrow in FIG. 1 and fruits such as oranges are fed from the fruit supply roller 17 to the receiving plate 18, it is lifted by the lifting tool 19 and becomes the funnel-shaped guide plate 12b. While the mandarin oranges enter and are supported and move in the direction of the arrow, the rubber hole 3 gradually expands, and according to the size of the mandarin oranges, they descend through the rubber hole 3, are sorted by size, and are taken out from the chute 23'. Further, the inner diameter of the rubber hole 3 can be adjusted to suit pears, so that pears can be sorted by size, and it can also be used for sorting summer mandarin oranges.

Conventionally, it has been difficult to mechanically sort large fruits that are easily damaged, such as tomatoes, pears, peaches, mandarin oranges, etc.
For different types of fruits of different sizes, such as mandarin oranges and summer mandarin oranges, it was necessary to use a special machine with a different structure.

Since the present invention is configured as described above, the fruit is placed in the rubber hole 3.
It is not only a scale that can automatically sort carefully, safely and reliably without causing damage due to the interaction of stepwise expansion and stepless expansion, but also a scale that can sort different types of different sizes without the need to use specialized machines with separate structures for each type. There are effects that can be applied to fruits.
