Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention defines a standard for sorting and sorting fruits and the like into a standard for price adjustment by individual and a sorting standard for sorting by shipping destination. The present invention relates to a method of separately setting and separately selecting and sorting.

[Conventional technology]

In recent years, a technique has been developed in which the fruits conveyed on a sorting conveyor are imaged using an imaging means such as a sensor camera, and the color, scratches, shape, etc. of the fruits are measured by the analysis, and the grade of appearance quality is automatically graded. It has been established and is being put to practical use.

According to the above conventional technique, the fruits brought in from each producer in the facility for sorting, packing, and packaging the fruits have a measurement value measured by the imaging means and a preset grade,
The class classification standard value is compared with each other to classify and classify the class, and the measurement data is output to perform price settlement processing based on the grade and the actual number by class of each producer.

[Problems to be solved by the invention] Markets of fruits to which fruits are sorted and sorted, depending on consumers, regions where high-quality products are selected, particularly high-quality tasted products, or markets that do not care about quality etc,
The demand for fruits tends to differ depending on the customer.

Further, the conventional sorting and sorting method is that sorting and sorting according to grade and class based on one sorting standard is performed and packaged and shipped, and the price is paid to each producer based on the data, For example, in this method, if the selection standard value is changed in order to meet the demands of different sellers as described above, there is a problem that some manufacturers may have troubles in price adjustment.

In other words, when shipping to an area where the shipping destination prefers a carefully selected product, the selection criteria are strict, so the ratio of high quality (excellent) is reduced and the ratio of low quality is increased, or In the opposite case, there is a problem that the ratio of excellent products is increased and the whole product is ranked in the upper grade, which makes it unfair to settle the price to the producer.

The present invention has been conceived in view of the above circumstances and technical background, and an object of the present invention is to carry out a finely sorted shipment as required by the market and consumers, and an equal and fair price settlement process by producer. Another object of the present invention is to provide a method for selecting and sorting fruits and the like that can be used.

[Means for solving problems]

The present invention, by imaging the fruits that are randomly conveyed from the previous process at irregular intervals before and after, to measure the outer shape and appearance state of the fruit by the analysis, based on the measurement values preset grade, class standard value and A sorting method in which the grade and rank are compared to each other, a sorting signal is output, and the class is sorted into each class, and the grade and class standard values are unbiased based on the sorting criteria set by the prefecture or the place of origin. Standard (standard)
And the sorting and sorting standards for each shipping destination are set separately, and by comparing the imaged measurement results with each other, the price calculation data for each individual and the sorting emission signal are separately output, and the grade for each class It is characterized by sorting.

〔Example〕

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing the overall configuration of a sorting and packing facility for fruits according to the present invention, the outline of which will be described.

1 is a supply device, 2 is a distribution supply device, 3 is an alignment supply device, 4 is an overflow carry-out conveyor, and 5 is a fruit selection device.

The supply width of the supply device 1 is preferably set equal to the reception width on the inlet side, which is determined by the number of threads to be distributed by the distribution supply device 2 in the next step, and is wide when the fruits are flatly gathered and supplied. It can also be configured by using the belt conveyor.

The distribution and supply device 2 forms a receiving portion 21 by adjoining the conveyors having a width that accommodates fruits in at most two rows at the start end portions, and forms the receiving portion 21 as it advances from the receiving portion 21. Gradually branching to widen the intervals between the strips, and the end portions of the strips are parallel to each other toward the downstream side aligning and feeding device 3 to feed the fruit. The applicant of the present invention has previously filed Japanese Patent Application No. 61-202822. It is preferable to use the device as proposed, but it further has a receiving portion 21 adapted to the feeding width of the feeding device 1, and as it progresses from the receiving portion 21, it is gradually branched and fed in parallel in multiple lines. Other mechanism may be used as long as it is a device capable of performing the above.

The aligning and feeding device 3 is configured to feed the fruits fed from the respective conveyors of the distribution and feeding device 2 in the previous process in a row using a row vibrating feeder.

Further, in the present embodiment, the vibrating feeder is used for the aligning and feeding device 3, but the invention is not particularly limited, and another mechanism may be used as long as it can feed the fruits in a line.

The overflow carry-out conveyor 4 is provided below the aligning and supplying device 2 and is provided so as to carry out an excessive amount of fruit that has temporarily overflowed on the aligning and supplying device 2 to the outside of the machine.
The overflow carry-out conveyor 4 is combined with a conveyer conveyor to form a return circuit so as to return the overflowed fruit to the supply device in the previous process.

The fruit sorting device 5 is configured as follows by combining a sorting conveyor 51, a measuring device 52, an arithmetic processing device 53 (see FIG. 2), and a drawing conveyor 54.

The sorting conveyor 51 separates the fruits one by one in a row and transports them forward and backward.
It is preferable to use a conveyor device of the type in which a special slat-shaped receiving plate is vertically tilted, which is proposed in Japanese Patent No. 26, but other sorting conveyors can also be used. The sorting conveyor 51 is provided with a plurality of strips of the same length, and the transportation speed thereof is higher than the transportation speed of the alignment supply device 3.

The measuring device 52 is configured using a known technique in which an illuminating device (not shown) and a camera device 521 are combined at a predetermined position from the starting end of the sorting conveyor 51.

FIG. 2 is an explanatory diagram of the arithmetic processing device 53, and FIG. 3 is a flowchart of a sorting and sorting processing sequence controlled by a program in the arithmetic processing device 53.

That is, the arithmetic processing unit 53, based on the measurement value of the shape of the fruit or the surface state measured by the camera device 521, the preset price adjustment counting standard for each individual and the sorting and sorting standard for each shipping destination, respectively. An arithmetic processing circuit (not shown) is configured so as to separately output the individual price adjustment count data and the sorting and sorting signal for each shipping destination by comparison.

The above-mentioned standard for individual price adjustment calculation is based on the sorting standard established by the prefecture or the place of production, and the set value changes according to the requirements of each shipping destination. It is a standard (standard).

In addition, the standard for price settlement for fruits that have been sorted and sorted is generally priced for the quality of the fruits. In other words, the higher the proportion of high quality (excellent), the better the price settlement for the producer, and the higher the proportion of low quality (good, average, etc.), the worse the price settlement.

In other words, even if the set value for sorting and sorting is changed according to the requirements of each shipping destination, the standard for price adjustment for producers, that is, the standard for individual price adjustment calculation, does not change. There are features that can be guaranteed.

The pull-out conveyor 54 is provided in the sorting discharge section 511 of the sorting conveyor 51 provided for each class in the direction across the sorting conveyor 51.

The pull-out conveyor 54 is configured by a method of gathering and carrying out small-width belt conveyors corresponding to each grade and a method of forming a carry-out path of each grade by providing a partition on the wide-width conveyor.

Reference numeral 6 denotes a conveyor, which is provided by using a belt conveyor having a small width in correspondence with each unloading path of each grade of the drawer conveyor 54.

7 is a boxing device for boxing and packing the fruits carried out according to each class and grade in a cardboard box.

Reference numeral 8 denotes a product transfer conveyor that joins the product boxes sent from the respective boxing devices 7 and transfers the product boxes.

With the above-described configuration, the fruit that is fully supplied by the supply device 1 is received by the receiving portion 21 of the distribution and supply device 2, is branched into a plurality of lines while being conveyed, and is supplied to the alignment supply device 3. The fruits supplied to the aligning and supplying device 3 are lined up in a row as they are conveyed and proceed, and are supplied onto the sorting conveyor 51.

When the fruit supplied with a proper gap provided in the front and rear of the traveling direction on the sorting conveyor 51 reaches the measuring device 52,
The camera device 521 images the shape and surface state of the fruit, and the calculation processing device 53 compares the individual price adjustment counting standard and the sorting and sorting standard for each shipping destination, respectively, and obtains the individual price adjustment counting data. And a sorting and sorting signal for each shipping destination are separately output, and the sorting and sorting signal for each class and grade is discharged onto the pulling conveyor 54. The fruits discharged onto the pull-out conveyor 54 are conveyed by the conveyer conveyor 6, packed in a box by the boxing device 7, and sent out.

The above description and the accompanying drawings are merely examples of the embodiment, and do not limit the invention, and the invention can be applied to other shapes and arrangements as long as the contents are set forth in the claims. Of course.

〔The invention's effect〕

The present invention, as described above, sets the grade and class setting standards for sorting and classifying according to grades, based on the selection standards established in prefectures and production areas, and based on the standard (personal price settlement standard) and shipping destinations. Since the method is set separately for the sorting and sorting standard, even if the setting standard is changed to meet many demands of the market and consumers, the price adjustment process for each producer is fair due to the unbiased standard. Can be done.

That is, it is possible to ship products that are finely sorted and sorted according to the different tastes of each regional market and consumers, and to guarantee the equality and fairness of individual price settlement processing to each producer, which is of great practical value. Is.
