Description

[Detailed Description of the Invention] The present invention relates to a fruit sorting device that can be used in a citrus fruit sorting plant to obtain the basic information necessary to properly settle the sales proceeds to each producer.

Conventionally, each producer takes samples of selected fruits brought to a joint fruit sorting facility at a certain rate, and an evaluator evaluates and appraises them based on these samples. There is a system that evaluates and scores the total amount brought in based on the data obtained by counting or weighing using a sampling machine and calculating the proportions of each class. Another method is to use a dial-type indicator scale on the weighing machine of the weighing and packaging equipment to visually read the number of boxes packed and the remaining amount less than one box (fractional weight) for each consignment, and calculate the weight by grade. There are also some methods of calculating and creating data.

These conventional apparatuses that evaluate samples have the disadvantage that if the fruits selected as samples are not mixed evenly and are unevenly distributed, the data will not be proportional to the total amount.

In addition, with the method of sorting each consignment and visually reading the weighed weight with a dial indicator scale, it takes some time to finish reading the 15 to 20 weighing machines, and during that time, the selected fruits of the next consignment are not selected. Since the fruit cannot be flushed, the loss time that occurs each time the consignment is changed is large, especially in large-scale fruit sorting plants that sort 200 to 300 consignments a day. This resulted in 300 minutes of lost time, which inevitably reduced the operating efficiency of the fruit sorting facility.

The present invention was made to eliminate these drawbacks, and the system selects the entire amount brought in rather than a sampling sample, processes the results on a computer, and evaluates and scores each consignment based on the net weight data. For this purpose, an electronic scale is installed in the packaging device installed at the end of the flow of selected fruits, and when a reload signal is received by the electronic scale, the computer can instantly check the boxed items. To provide a device which reads and integrates the weight of selected fruits and the weight of the remaining amount (fractional amount) less than one box, and minimizes loss time caused by changing loads.

The present invention is equipped with an operation console that allows the producer code number, brought-in weight data, and reload settings to be entered into a computer for each consignment when the selected fruits are delivered to the consignment receiving device. Connected to a computer, and according to the cargo transfer settings, each weighing box is packed at the branch terminal section where the flow is divided into each grade class from the cargo receiving and supplying section, through a grade manual sorter, and a grade sorting device that sorts selected fruit by forming. Each device is synchronized with the flow of selected fruits and sends a reloading signal sequentially according to the distance, and each weighing and packing device is equipped with an electronic scale and connected to a computer, and the selected fruits for each consignment are Based on the reload signal sent in synchronization with the last end of the flow, a computer calculates the total weight of each electronic scale, including the fraction of the amount remaining.
In addition, the yield rate after removing inferior products is calculated from the total cumulative weight of each consignment and the ratio of the total cumulative weight to the brought-in weight, and the results of fruit sorting are obtained as weight data for each consignment. .

In addition, in this device, a part of the grading manual sorting device is equipped with a device that indicates the change of consignment by a change signal sent from the consignment supply section to the grading manual sorter in synchronization with the flow of selected fruits. , the flow of subsequent parcels (supply side) will be temporarily stopped if the spacing between parcels is closer than the appropriate interval at the exit of the grading manual sorter, or if an abnormality occurs in the subsequent process and the previous parcel stagnates. A control circuit is provided to control the loading time, so that the spacing between parcels is always maintained at an appropriate level, thereby reducing lost time during loading and unloading.

The interval between the previous consignment and the subsequent consignment controlled by the receiving and supplying section is determined by the computer reading the remaining weight on the electronic scale based on the reload signal at the end of the flow of selected fruits, that is, at the weighing and packaging device. After that, the next consignment may be placed in the box on the electronic scale, so the layout of each facility is determined so that the end point of the flow is only slightly apart.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Diagrams showing embodiments of the present invention will be described below.

Reference numeral 1 denotes a cargo receiving device section, which is composed of a cargo receiving conveyor 2, a supply device 3, and a supply conveyor 4. The receiving conveyor 2 differs depending on the type of container 5 for carrying in the selected fruit and the receiving system, and may be a slab conveyor, a roller conveyor, a chain conveyor, or sometimes a forklift or a container elevator. The feeding device 3 discharges the selected fruit 6 from the carry-in container 5 onto the feeding conveyor 4, and various known devices can be used depending on the type of the container 5, the type of the receiving conveyor 2, and the receiving system.

7 is a pre-processing device, which uses washing, cleaning, wax application, and drying devices, as well as human hands, to eliminate inferior products such as rotten fruits and damaged fruits, and to grade the selected fruits 6 to quality such as excellent, excellent, and good. It includes a conveyance device to a grade manual sorter 8 for sorting into grades. Reference numeral 9 is a small bead removal machine that extracts the selected fruits 6 smaller than a predetermined size, and depending on the layout of the fruit sorting facility, the feed conveyor 4
In some cases, it is provided between the preprocessing device 7 and the preprocessing device 7, and in other cases, it is provided after the preprocessing device 7 and between the grading manual sorter 8.

10 is a grade sorting device that sorts selected fruits according to their shape; after the grade hand sorter 8,
There are cases where the water is divided into separate streams for each grade such as Excellent, Good, etc., and cases where the grade hand sorter 8 is placed in front of the grade hand sorter 8 and after sorting, the grade hand sorter 8 is arranged for each grade such as S, M, L, etc. There is. Reference numeral 11 denotes a branch conveyor that conveys selected fruits sorted by grade and class to weighing and packaging devices 12 provided for each grade and class.

The above-mentioned fruit sorting facilities are well known, but the present invention provides for each weighing and packaging device 12 provided at the final end of the flow of selected fruits, that is, at the end of each of the branch conveyors 11, in such a facility. , an electronic scale 13 for weighing the boxed weight of the selected fruits packed in a box is provided, a computer 14 is provided connected to each of the electronic scales, and a computer 14 is provided near the supply device 3 of the cargo receiving device section 1, and a computer 14 is provided for weighing the boxed weight of the selected fruits packed in a box. An operation console 15 is provided for inputting data on producer code No., total weight brought in, and reload settings, and is connected to a computer 14 to store the data. The reloading signal 16 inputted by the reloading setting is sent to a display device 17 provided in a part of the grade manual sorter 8 that displays the number of consignments to be changed, and also to a display device 17 which is the end point of the flow of selected fruits and is sorted into each grade class. Each weighing and packaging device 12 that flows
The fruits are sent to the electronic scale 13 in synchronization with the final end of the flow of selected fruits in the consignment.

At the same time as the selected fruit in the consignment being weighed and boxed (injected) in each weighing and packing device 12 finishes flowing, or in response to a reloading signal that is sent shortly, the computer 14 uses its electronic scale 13 to select the fruit that is being weighed and boxed. The remaining fractional weight of less than one box is read, and the total weight of the parcel is calculated for each electronic scale from the weight of the selected fruits that have already been boxed and weighed and sent out and the remaining fractional weight. Furthermore, the computer 14 calculates the total cumulative weight of the consignment by adding up the calculated weights for each grade class (each electronic scale), performs other necessary arithmetic processing, and prints and issues the data on a slip. Other methods include recording on tape.

In addition, the above-mentioned other necessary calculation processing is based on the weight brought in, and the amount of spoilage during the sorting process.
Since the out-of-grade products excluded due to scratches and other defects will reduce the yield weight, the yield rate after removing these out-of-grade products is calculated from the brought-in weight and the output weight, and the yield rate is determined by each fruit sorting facility. It is to perform calculations according to the display items of the received slip.

The weighing weight reading by the computer 14 using the reload signal 16 is carried out instantaneously for each electronic scale, and then
Since the system switches to the receiving mode for the next consignment, the weighing and packing equipment section is not allowed to receive the next consignment after a short interval, so there is an extremely large amount of lost time due to temporary suspension of the consignment change. It becomes less.

In addition, in the grading manual sorting section, the change of consignment is displayed on the display device 17 in synchronization with the flow of selected fruits, so that at the exit of the grading manual sorter 8, the rear end of the previous consignment and the subsequent consignment are displayed. The grading hand sorter judges whether the distance between the grading hand sorter 8 and the front end of the grading hand sorting machine 8 is appropriate, and if it is too close and there is a risk of contamination, the grading hand sorter 8
and each machine in the preceding process is temporarily stopped and controlled to provide the necessary interval.

Therefore, in the receiving and supplying department, if the distance between consignments is not too large and the consignments are supplied in such a way that they do not get mixed up in the process up to the manual grading section, the grading manual sorting section can control the intervals at regular intervals, minimizing loss time. This allows for efficient fruit sorting.

Incidentally, the small mandarin oranges extracted by the small fruit extracting machine 9 are processed by an electronic scale 19 that receives one of the reload signals sent in synchronization with the last end of the flow of the selected fruits. The weight is read and memorized by a computer each time, and when the consignment is weighed and packed into a box, the computer processes it.

Incidentally, the reference numeral 20 in FIG. 1 indicates a conventional sampling machine.

The present invention is equipped with an operation console that inputs the producer code number and carry-in weight data and reload settings for the consignment into a computer when starting to supply the selected fruits to the consignment receiving device as described above. An electronic scale is installed in the weighing and packing device at the terminal end where the selected fruits are sorted and separated into pieces, and a computer is connected to these scales to control the flow of the selected fruits in the consignment according to the loading change settings. Sends a reload signal in synchronization with the last end of the
Every time the signal reaches each outlet (each electronic scale) that is the end of the flow of selected fruits, the boxed weight of the selected fruits sent to that outlet is instantly read and the cargo is packed into boxes according to its grade. The total weight, the total weight of the fruit sorted, and the yield rate after removing out-of-grade products are calculated to provide fruit sorting data based on actual weight, so each producer can be satisfied with fruit sorting data based on actual weight. Not only can a proper evaluation be obtained, but also the next consignment may arrive at the weighing and packaging device section after a short interval, so the loss time for changing consignments can be extremely reduced.

In addition, the present invention inputs the weight of one consignment as data into a computer, and uses the computer to calculate the yield rate by removing out-of-grade products from the total boxed weight of selected fruits after sorting in that consignment. As a result, the rate of defective products such as rotten fruit and damaged fruit can be determined, and producers can refer to this and plan to reduce the number of defective products.

Furthermore, the present invention uses an electronic scale at the end of each branch for each grade class to measure the total weight of the selected fruit for each consignment, so the fruit sorting device installed in the grade sorting process is a sieve or the like. It can also be used in shape sorting machines that do not weigh individual fruits, such as drum-type fruit sorters and belt-type fruit sorters that pass through holes in a large number of fruits at once.
