Description

DETAILED DESCRIPTION OF THE INVENTION A device is provided in which expandable and contractible rubber holes are arranged in series in the moving direction, and the rubber holes are sequentially enlarged from the starting end to the terminal end in the upper transition section of the conveyor, so that each rubber hole is on the same plane. This relates to a fruit sorting machine that can be expanded and contracted steplessly in multiple radial directions, and its purpose is to sort fruit carefully so as not to damage the fruit.

To explain the embodiment of the present invention shown in the drawings, two endless chains 74, 4 are wound around a driving sprocket 6 and a driven sprocket 7 on a 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 at regular intervals.

A through hole 5a is formed in the center 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 arc-shaped guide holes 10 are drilled in the same plate 8 so as to cross the radial direction, and six arc-shaped guide holes 10 are provided in the same plane between the same gate plate 8 and the base plate 5. A sliding piece 12 that can freely slide in the radial direction is provided between the radial direction guides 11, 11, and a pin l protruding from the sliding piece 12 is provided.
3 are slidably fitted into the arc-shaped guide elongated holes 10, respectively.

Rubber is attached to the tip edge 12a of each sliding piece 12, and expandable and contractible rubber holes 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 date plate 8, and the protrusion 14 and the support shaft 9a of the guide roller 9 are connected by a spring 15, and the machine frame is
The projection 14 is guided and rotated from the solid line position in FIG. 4 to the imaginary line position against the spring 15 by a guide kite 16 provided at
In the upper transition section of the conveyor 2, a device can be provided that enlarges the rubber hole 3 in four stages using four guides 16 sequentially from the start end to the end end. 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. In the figure, 17 indicates a fruit supply roller, 18 indicates a fruit receiving plate, 19 indicates a supplying fruit lifting device, and 20 indicates a position adjustment screw on the guide 16.
21 is a set screw of the guide 16, and 22 is a tool for pushing up the center of the expandable rubber hole 3.

Therefore, when the conveyor 2 is moved in the direction of the arrow in FIG. 1 and fruits such as tangerines are fed from the fruit supply roller 17 to the receiving plate 18, they are lifted by the lifting tool 19, enter the funnel-shaped guide plate 12b, and are supported in the direction of the arrow. While moving, the above rubber hole 3
are gradually enlarged and descended from the rubber hole 3 according to size, and the chute 23 is also taken out after being sorted by size.

Conventionally, it has been difficult to mechanically sort large fruits that are easily damaged, such as tomatoes, pears, peaches, mandarin oranges, etc., but since the present invention is configured as described above, the fruits can be sorted stepwise and steplessly through the stepwise expansion of the rubber hole 3. The interaction with magnification has the effect of automatically sorting carefully, safely, and without causing damage.
