Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fruit sorting and feeding device for a fruit sorting machine that sorts fruits, root vegetables, etc. according to shape and the like.

For this type of fruit sorting machine, it is important for sorting accuracy to efficiently feed fruits one by one at regular intervals onto the fruit sorting conveyor that conveys the fruits to a photoelectric measuring device that determines the shape of the fruits. and is extremely important for efficiency.

This invention has taken the following technical means to achieve the above object.

That is, a set of three brush rolls 1, 1 with brushes planted at an angle in the conveying direction A are rotatably mounted on shafts, and a short length is formed on the terminal end side of the central brush roll 1'. roll 1'
The rear part is formed into a confluence section 2 for fruits that are mounted between the three brush rolls 1, 1', and 1 and conveyed in alignment, and from the confluence section 2, the fruits are conveyed to a fruit sorting conveyor 4 by a transfer belt conveyor 3. The arrangement and supply device in the fruit sorting machine is configured as follows.

In the illustrated example, 5 is a support stand, and 6 is a diffusion roller conveyor, in which a plurality of rolls 8, 8 are mounted between a pair of left and right chains 7, 7, and are driven in the direction of arrow A, as well as a sliding guide. The rolls 8, 8 are configured to rotate by contact with the roller 9. 10 is a drive motor, and 11 is a drive chain.

Behind the diffusion roller conveyor 6, a set of three brush rolls 1, 1, and 1' are mounted on shafts facing the conveyance direction A, and have brushes planted on the outer periphery at an angle toward the conveyance direction. A plurality of sets are provided on a gentle slope, and the elasticity of the brushes is to be applied to the fruit placed between the pair of brush rolls due to the rotation of the brushes,
This is configured to roll on the oblique side of the brush.

12 is a drive motor, 13 is a drive chain, 14
is a supporting frame, which is configured to be able to drive and rotate the brush rolls 1, 1.

The central brush roll 1' of the set of three brush rolls 1, 1 has a short terminal end, and is configured as a merging section 2 for two rows of fruits conveyed behind it.

Reference numeral 15 denotes a chevron-shaped guide, which is formed to cover both the outer rolls 1 and 1 of the three brush roll groups A and the adjacent brush roll group A from the front to the starting and short sides. , 1, and to guide fruit between the central brush roll 1' and both side brush rolls 1, 1. The guide 15 is a diffusion roll conveyor 6
A mounting plate 17 installed between the extensions of the side plates 16, 16
is suspended from the 18 is a guide board.

A transfer belt conveyor 3 is arranged behind the merging section 2 behind the central brush roll 1'.
The transfer belt conveyor 3 conveys fruits from the merging section 2 to the rear fruit sorting conveyor 4, and is wound between a large-diameter pulley 19 and a small-diameter pulley 20, and is connected to a drive motor 21 and a drive chain 2.
It is configured to be driven by 2.

Reference numeral 23 denotes a guide chute for the transfer belt conveyor 4, which is formed by a bottom plate 24 and side plates 25, 25 on both sides of the transfer surface of the transfer belt conveyor 4. Also, the side plate 25 of the guide chute 23
An overflow roller 26 is formed by cutting out a portion of the roller, and a transfer conveyor 28 is provided which connects the overflow roller 26 to a collection conveyor 27, which will be described later.

The collection conveyor 27 is disposed behind the brush rolls 1, 1 and perpendicular to the conveyance direction, and collects the surplus fruits loaded and conveyed between the brush rolls 1, 1 on both adjacent outer sides of the brush roll groups A, A. and is configured to be transferred to one side.

Reference numeral 29 is a return conveyor, which connects the collecting conveyor 27 and the spreading roller conveyor 6.

Further, brush rolls 30, 30 for transferring surplus selected fruit are provided on the outermost sides of the brush roll groups A, A.

Fruit sorting conveyor 4 is transfer belt conveyor 3
The chain 32 has a starting end below the terminal end thereof and is wound around a sprocket 31, and a large number of narrow flats 33, 33 are attached to the chain 32.

The fruits fed onto the spreading roll conveyor 6 are
The rotation of the conveyor 6 in the direction of arrow A and the rolls 8, 8
As it rotates, it is transferred onto the guide plate 18 while being diffused sequentially, and is then transferred by the guide 15 between the center brush roll 1' of the set of three brush rolls A and the left and right brush rolls 1, 1. is supplied to

When the brushes rotate, the fruit fed between a pair of brush rolls 1, 1', and 1 in a set has elasticity on the slanted side of the brush, and moves toward the slanted side, that is, the merging section 2 side. It is transferred while rolling. Also, when two or more fruits are polymerized, they are pushed out from the adjacent brush roll and transferred under the same action.

The two rows of fruits conveyed between the central brush roll 1' and the brush rolls 1, 1 on both sides fall to the confluence section 2 at the end of the central brush roll 1',
Next, the fruits are transferred from the left and right by the transfer belt conveyor 3 while being arranged in a line from the left and right by the extended brush rolls 1, 1 on both sides.

Fruits which have not yet been arranged in a line on the transfer belt conveyor 3 are discharged from the overflow roller 26 and transferred by the transfer conveyor 28 to the collection conveyor 27.

In addition, fruit that overflows from the brush rolls 1, 1', 1 and is loaded between the adjacent brush rolls 1 is collected from the ends of the brush rolls 1, 1 to the collection conveyor 27, and is spread via the return conveyor 29. It is returned to the conveyor 6.

Transfer belt conveyor 3 to fruit sorting conveyor 4
The fruits arranged in a line to be supplied to the fruit sorting conveyor 4, which rotates at a slightly higher speed than the transfer belt conveyor 3, are conveyed with a large distance between each fruit, and are accurately measured by a photoelectric measuring device or the like. The fruits are then sorted by measuring their size and other factors.

In this invention, two rows of fruits that are efficiently arranged and conveyed by a set of three brush rolls are merged at the end of a central short roll conveyor, and are further conveyed in one row by brush rolls on both sides of the merged portion. Since the fruits are arranged in rows and sent to the fruit sorting conveyor via a transfer conveyor, they can be fed to the fruit sorting conveyor in a high-density manner without overlapping each other, allowing for efficient and accurate fruit sorting. be.
