Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a device for automatically separating and supplying the objects to be sorted 1 one by one to a weight sorter 2 that sorts the objects to be sorted 1 such as potatoes and agricultural products having a shape similar to that of potatoes. It is about.

[0002]

[Prior art]

 Conventionally, this kind of thing is as follows. The weight sorter 2 has a large number of sorting buckets 3 each accommodating one to-be-sorted object 1, which are connected by a chain or the like and formed into an endless conveyor. The sorting buckets 3 are continuously moved while the sorting buckets 3 are continuously moved. It is configured to receive the sorted products 1 one by one. The objects to be sorted 1 are first accommodated in the hopper 4, and then are installed corresponding to the positions of the rows of the sorting buckets 3, and the rollers 6 are connected in an endless shape and are provided with the recesses 7. It is sent to the sorting bucket 3 one by one via the conveyor 5. Guide plates 8 for guiding the objects to be sorted 1 are provided on the left and right of the roller 6.

Each sorting bucket 3 has a weighing device, and is configured to drop the sorting target 1 downward at a predetermined position while moving according to the weight of the sorting target 1. If a plurality of objects to be sorted 1 are delivered to the sorting bucket 3 with a plurality of recesses 7 in one place, sorting for that portion becomes invalid, so that the supply conveyor 5 always has a worker. In the present situation, if there is more than one in the hollow 7 at one place, it is removed by hand and sent as a single piece.

[0004]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. As described above, in the weight sorter 2, when a plurality of objects to be selected 1 are placed in one sorting bucket 3, the total weight is measured, and sorting for that bucket becomes invalid. Therefore, it is very difficult for the subsequent processing to occur, so personnel must be assigned to each line of the supply conveyor 5, and the transport state of the supply conveyor 5 should be observed, and a plurality of objects should be placed in one cavity. If there is a Sorted Product 1, be sure to remove the excess and make it a single item. Also, the faster the feeding speed in order to improve the sorting ability, the more the fatigue level of the above-mentioned working staff must be increased or the number of staff must be increased.

The present invention has been made in view of such problems of the conventional technology, and an object of the present invention is to provide the following things. In other words, a device for automatically preventing a plurality of objects 1 to be sorted from entering the sorting bucket 3 of the weight sorting machine 2 is provided to prevent a trouble in the weight sorting, and the supply conveyor 5 which is conventionally required. The work cost is reduced by eliminating the need for workers in the parts, and at the same time, the unmanned supply section aims to improve the sorting capacity to the maximum capability of the weight sorter 2 itself. .

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. In order to automatically prevent a plurality of feeds to each sorting bucket 3 of the weight sorter 2, first, from the hopper 9, between the weight sorters 2, a pair of surfaces are covered with brushes and rotated in the same direction. The brush rollers 10 are arranged in parallel with each other and installed at an appropriate downward inclination with respect to the weight sorter 2 to form a guide path for the objects to be sorted, and a plurality of them are forcibly prevented from being fed to the leading end thereof. An automatic separating drum 11 is arranged, and is passed from the chute 12 to the sorting bucket 3 of the weight sorting machine 2 from there.

The automatic separating drum 11 has a pair of left and right disks 13, a boss 14 penetrating the center of the disk 13, and a fan shape in a side view. The circumference of the disk 13 is equally divided radially from the center of the disk 13. However, the outer circumference is concentric with the disk 13 and the radius is smaller than the disk 13, and the partition plates 15 each having an arc shape are fixed to the pair of disks 13. That is, the partition plate 15 has a bag-like closed structure in appearance. Only one object 1 to be sorted enters the accommodation portion 16 constituted by the gap between the partition plates 15 and is sent by the rotation of the automatic separation drum 11, and the angle of the plate of the accommodation portion 16 that is being received descends to some extent. When it becomes, it falls on the chute 12 and is guided into the sorting bucket 3 of the weight sorting machine 2. The positional relationship of delivery of the objects to be sorted 1 between the automatic separating drum 11 and the sorting bucket 3 depends on the setting of the number of teeth of the sprockets 19 and 20 for driving the automatic separating drum 11 from the weight sorter 2 so that the delivery is synchronized. It is configured to maintain sex.

The width and outer diameter of the pair of disks 13 and the number and size of the partition plates 15 are made to correspond to the size range of the objects to be sorted 1. For example, if the item to be sorted 1 is potato, there are varieties close to spherical and long and narrow varieties. Therefore, the number of L's corresponding to the partition plate 15 can be used so that the automatic separating drum 11 itself can be used without replacement. A plate L plate 17 configured in a shape is provided. When selecting long and narrow products, the size of the automatic separating drum 11 is set within a range in which only one object 1 to be sorted is accommodated in the accommodating portion 16 without using the L plate 17, and the L plate 17 is used. Work without doing.

Next, in the case of selecting a product having a shape close to a sphere, the container 16 of the objects to be selected 1 may be deep and the two may be accommodated as it is. And fix both sides with bolts 18. With this configuration, the same automatic separating drum 11 can be used for sorting objects 1 having different shapes. For items other than the exemplified potatoes, the automatic separating drum 11, the partition plate 15, etc. The configuration of the present invention can be used in a wide range of fields by adapting the size range of the sorted product.

[0010]

[Action]

 The objects to be sorted 1 housed in the hopper 9 are arranged from the lower part thereof toward the automatic separating drum 11 with an appropriate downward gradient, and the hopper is placed between the valleys of a pair of brush rollers 10 rotating in the same direction. It is sent from the exit of 9 while rolling. Since the pair of brush rollers 10 rotate in the same direction, the objects to be sorted 1 are smoothly sent out one after another while rotating in the opposite direction to the brush roller 10 and reach the automatic separating drum 11. The automatic separation drum 11 is rotated by a sprocket 20 via a sprocket 19 and a chain 21 provided on the shaft of the weight sorter 2, and the automatic separation drum 11 and a storage portion 16 that receives the objects 1 to be sorted are sorted. The transfer positions of the objects to be sorted 1 between the buckets 3 are synchronized.

When the object 1 to be sorted reaches the automatic separating drum 11, while the accommodation portion 16 of the partition plate 15 of the automatic separating drum 11 rises from below and the positions of the object 1 to be sorted match. Since a force to move forward is exerted on this, one of them enters the accommodating portion 16 of the automatic separating drum 11. The depth of the storage section 16 is set so that even the smallest one to be applied to the weight sorter 2 of the objects to be sorted 1 will not accept two pieces, so even if a part of the second piece is located at the end of the storage section 16. Even if it is hooked, the automatic separating drum 11 is rotating, so that the accommodating portion 16 moves upward, and the second one does not rest on the accommodating portion 16 and slides against the outer periphery of the partition plate 15. When the accommodation section 16 arrives, it enters the accommodation section 16. That is, no more than one item to be sorted 1 is sent at one time.

As for the objects 1 to be sorted that are close to spherical and may enter two in the accommodation portion 16 of the automatic separation drum 11 having the same size, as described above, by using the L plate 17, You can prevent multiple feeds by making the depth shallow. Due to the rotation of the automatic separating drum 11, the objects to be sorted 1 slide down when the angle of the plate being received is downhill to some extent and are transferred to the sorting bucket 3 of the weight sorter 2 via the chute 12. , Selection is done.
