Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a device comprising a fruit feeding section provided on a machine frame and a sorting section for moving the fruit in the feeding direction a, in which the feeding section is placed in the upper stage and the sorting section is placed in the upper stage. A fruit intermittent feeding device is provided at the lower level, and the fruit feeding speed by the feeding device is smaller than or the same as the fruit moving speed by the sorting section, and one pair is provided on the horizontal rotation axis perpendicular to the feeding direction. a rotating plate, a plurality of small cylinders are interposed between the rotating plates at equal intervals on the outside of the rotating shaft, and a fruit feeding resistance elastic member that can be freely opened and closed between the pair of rotating plates. This invention relates to a fruit sorting machine that is provided with a plate to form the above-mentioned intermittent fruit feeding device, and is intended to smoothly and reliably sort tomatoes and the like according to size.

To explain the embodiment of the present invention shown in the drawings, the machine frame 1
A rotating spiral brush 2 and a rotating cylindrical brush 3 are placed close to each other and supported parallel to each other, a fruit 4 such as a tomato is supplied between both brushes 2 and 3, and the fruit 4 is fed by rotating the spiral brush 2. is transferred in the direction of arrow a to form the fruit feeding section 5.

A fruit sorting section 6 is provided following the feeding section 5 as described above, and the feeding section 5 is arranged in the upper stage and the sorting part 6 is arranged in the lower stage.

The sorting unit 6 has a fixed plate 7 and a fixed cylinder 8 installed close to each other in parallel, the center axis of the cylinder 8 being parallel to the feeding direction a of the feeding unit 5, and the fixed plate 7 sequentially arranged with a curvature. Large circular arc notch 9
A plurality (four) of circular grooves 10 having the same curvature as the notch 9 are formed in the cylinder 8 at positions corresponding to the notch 9.

A rotating spiral 11 for moving the fruit 4 in the direction of arrow a is provided on the outer periphery of the fixed cylinder 8.

This spiral 11 has arrows a on both sides of the notched groove 10.
It is preferable that the portion perpendicular to the direction be formed in an N-shape.

A horizontal rotating shaft 12 orthogonal to the direction of the arrow a is provided at the intermediate step between the feeding section 5 and the sorting section 6, and a pair of opposing rotating plates 13, 13 are provided on the same axis 12, and A sponge board is pasted on the surface, and multiple (3 pieces) are attached between the same rotating plates 13 and 13.
Small cylinders 14, 14, 14 are interposed at equal intervals on the outside of the rotating shaft 12, and each of the small cylinders 14.14 is freely supported.

These small cylinders 14 are formed by covering the outer periphery of a sponge layer provided on the outer periphery of the support shaft 15 with a leather tube.

An elastic plate 16 made of rubber is suspended between the rotary plates 13 and 13 at the stop on the side of the feeding section 5, and its elasticity provides resistance to the fed fruit 4 and is controlled by the feeding pressure of the fruit 4. This is opened, and the fruit 4 is passed from the feeding section 5 onto the small cylinders 14, 14, and after passing, it returns to its original position due to its elasticity, and the feeding section 5 is closed, and one fruit 4 is delivered onto the cylinder 14, 14. It is possible to form a device 17 that can feed the fruit 4 to the sorting section 6 intermittently by rotating the small cylinders 14, 14 in the direction of the arrow.

The pulley 18 provided on the horizontal rotation shaft 12 and the pulley 20 provided on the intermediate shaft 19 were connected by a belt 21, and the pulley 22 provided on the rotation shaft of the spiral 11 and the pulley 20 provided on the intermediate shaft 19 were connected by a belt 21. Pulley 2
3 is connected by a belt 24, and the fruit feeding speed by rotating the small cylinders 14, 14, 14 in the direction of the arrow and the spiral 11
The above-mentioned feeding speed can be made smaller than or equal to the above-mentioned moving speed by linking the fruit moving speed according to the above-mentioned fruit moving speed.

In addition, 25 in the figure is the prime mover, 26 is the reduction shaft, 27,
28 is a reduction pulley between the reduction shaft 26 and the intermediate shaft 19, 29 is its reduction belt, 30 is a motor shaft pulley, 31 is a reduction pulley,
32 is a reduction belt, 33.34 is a rotating pulley for the brush, 3
5 is its rotating belt, 36 is a fruit guide brush provided on the feeding section 5, 37 is a guide plate, 38 is a sorting fruit guide chute, 3
9.40 is an unsorted fruit guiding chute.

Conventionally, unsorted fruits supplied from the unsorted fruit feeding section to the sorting section are difficult to feed to the sorting section in an orderly manner, and they scatter and roll in the feeding direction, climbing over large-sized fruits on the smallest notch and falling into small-sized fruits. Tomatoes, pears, apples, and peaches have a serious defect that causes objects to fall into the dog-sized cutout, which confuses sorting by size and makes sorting difficult. etc., because they are easily damaged by being pushed up by the rising edge, making it difficult to apply to these fruits, making it difficult to serve as a sorter, and making it difficult to put it into practical use.

As described above, the present invention arranges the feeding section 5 at the upper stage and the sorting section 6 at the lower stage, and arranges the intermittent supply device 17 at the stepped portion, and the supply speed by the device 17 is lower than or equal to the moving speed by the spiral 11. Since they are formed identically, the fruits 4 supplied to the sorting section 6 can be supplied one at a time, and can be adapted to the moving speed of the spiral 11, so that each fruit 4 can be reliably selected. A pair of rotating plates 13, 13 are provided on the horizontal rotating shaft 12 perpendicular to the feeding direction, and a plurality of small cylinders 14, 14, 14 are installed between the rotating plates 13°13. The pair of rotating plates 13.13 are arranged on the outside at equal intervals, and
Since the intermittent fruit feeding device 17 is formed by providing a fruit feeding resistance elastic plate 16 that can be opened and closed between them, the tomatoes, apples, pears, peaches, etc. to be fed are carefully and smoothly delivered one by one. There are practical benefits that can be applied to the selection of these soft premium fruits without risk of damaging them.
