Abstract

PURPOSE:To drop securely sample fruits by disposing a rotor on both sides (one side) of a dropping opening in the method of dropping fruits and making them sample fruits in the middle of a conveyor dispersing and feeding the fruits delivered. CONSTITUTION:Fruits delivered, for instance, citrus fruits are transferred while rolling on a roller conveyor 1 surface. During said transfer, a class evaluator inspects the appearance and takes out non-standard articles to the outside of transfer circle, while remaining fruits reach rollers 5, 5.... The fruits are transferred to the starting end side of the following roller conveyor 2 while rolling by the rotation (A) of the rollers 5, 5.... At that time, when the fruits reach a dropping space (B) in which roller 5 is absent, the same drop downward and are received by a sample drawing conveyor 6 as sample fruits. Said sample fruits are passed through a class evaluation device and number ratio is computed for different diameter-wise to set actual numbers at a class-wise discharge outlet. The sample fruits reaching to the dropping space (B) are dropped onto the drawing conveyor 6 securely without accumulating because of what is called bridge by the rotation of rollers 5, 5....

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a sample taking device in a fruit sorting machine.

[1llllJI that the prior art and the invention try to solve
) There is a method in which a portion of received citrus fruits, etc. is taken out as a sample, and the class etc. is determined, and each consignment is evaluated. For this reason, conventionally, as shown in FIG. 4, a chute C section for handing over from the upper roller conveyor a to the lower roller conveyor b is provided with an opening/closing plate d that is narrow in the middle of the left and right sides, and the opening/closing plate d It is opened to form an opening e, and a part of the consignment fruit is dropped into the sample drawer conveyor f below.
The system is such that they are evaluated as appropriate.

However, in the above embodiment, there is a risk that the fruit reaching the opening may exhibit a bridging phenomenon and may not fall downward.

[Means to solve the problem]

The present invention attempts to solve the above-mentioned drawbacks, and in a device in which a part of the supplied fruit is dropped in the middle of the conveyors 1 and 2 that receive and distribute received fruit and taken out as a sample fruit, both sides of the falling space opening or one The structure of a sample extraction device in a fruit sorting machine is such that rotary bodies 5, 5 which are driven and rotated are disposed on the sides.

[Operation and effect of the invention]

Because the rotating body is rotating, the sample fruit that reaches the opening of the falling space is carried around by the inner edge of the rotating body, and will not be stagnated by a so-called bridge, and will surely fall, so the sample fruit will fall without fail. This eliminates the drawbacks of the

〔Example〕

An embodiment of this invention will be described based on the drawings.

1 is a roller conveyor that receives and transfers received citrus fruits, and grading personnel are on standby on the left and right sides of this conveyor 1 to inspect the appearance of the rolling fruits and take out those that are not in the grading range. There is.

Reference numeral 2 denotes a spreading roller conveyor, which receives the fruit from the roller conveyor 1 and transfers it to the following sorting conveyor 1, etc.

A sample extraction device 3 is provided between the roller conveyors 1 and 2. The take-out device 3 includes a plurality of rollers 5, 5, . A part of the rollers 5, 5, etc., which are integrally rotatably fitted to a shaft 7 that is linked to the motor 4, is removed, that is, a fruit falling space opening is formed in a part of the left and right middle. The fruits that fall from the space opening reach the sample drawer conveyor 6 below, and the remaining fruits reach the rollers 5 and 5.
. . and is supplied to two surfaces of the roller conveyor.

A sample evaluation device (not shown) is provided at the end of the sample drawer conveyor 6 to inspect the class, that is, the outer diameter, of the sample fruits that are arranged and transferred.

This is a configuration in which the proportion of classes such as L can be predicted.

FIG. 2 shows a second embodiment, in which brush rollers 10 are interlocked with motors 9, 9 to drive and rotate in the direction of the arrow on the left and right sides of the falling space C in the middle of the transfer chute 8 from the roller conveyor 1 to the roller conveyor 2. 10 are arranged.

In addition, in the third embodiment shown in the third garden, the brush roller 1
0 and 10, rubber disks 11 and 11 are provided to be driven and rotated in the direction of the arrow.

Explanation of the operation of the upper side - Citrus fruits, for example, received and supplied by a container damper or the like are transferred while rolling on one surface of the roller conveyor. During this transfer, a first grade evaluator inspects the appearance and removes out-of-grade items such as scratches, poor coloring, and small beads to a place outside the transfer range.

The remaining fruit reaches rollers 5, 5... parts. here,
Due to the rotation of the rollers 5, 5, etc., it moves to the starting end side of the next stage roller conveyor 2 while rolling.

By the way, when the fruit reaches the opening of the falling space where there is no roller 5,
The samples fall downward and are received by the sample drawer conveyor 6. When the sample fruit passes through the class evaluation device section at the terminal end of the drawer conveyor 6, the number ratio is calculated for each outer diameter, and the class ratio for a certain consignment is predicted before entering the sorting process and classified. This is convenient for specifically setting the number of discharge ports.

The sample fruit reaching the opening of the falling space is transported by rollers 5°5...
Since it is rotating, it is not carried around by the inner periphery of the rollers disposed on the left and right sides of the falling space opening and is prevented from being stagnated by a so-called bridge, and can reliably fall onto the surface of the drawer conveyor 6.

Similarly in the second and third embodiments, the brush rollers 9, 9 and the rubber disks 10, 10 prevent the sample fruit from stagnation and ensure that it falls.
