Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a device for sorting vegetables, fruits, etc., which has a compact structure and can be efficiently operated. Rollers and soft rollers are arranged in parallel alternately, and each roller is a combination of a stepped roller and a rod-shaped roller, or a combination of stepped rollers, and the stepped roller is arranged in the direction of movement of the objects to be sorted. In addition to arranging the rollers in a direction that gradually increases the distance between them, the rollers may be arranged so that they both rotate in the same direction, or the rollers may be arranged so that the distance between the opposing rollers is gradually increased. The purpose is to ensure that the sorting is performed without rotating toward the direction.

An example of the implementation of the device of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a plan view showing the arrangement of each roller, and in this figure, 1 and 3 are three-stage hard rollers, and 2 is a two-stage soft roller.

In the present invention, the hard roller refers to a roller made of wood, hard rubber, soft plastic, metal, or the like.

On the other hand, soft rollers include brush rollers, raw rubber with an elastic hardness of about 200 to 400, synthetic rubber, foam materials (latex foam, ohm, polyurethane foam, polyethylene foam, etc.), fabrics (paper packages, blankets), etc. Those with 3 wL or more pasted are considered to be considered. On the other hand, in the present invention, these hard rollers and soft rollers are arranged alternately, and this is done so that the dimensions of the gaps between each roller and the objects to be sorted are as equal as possible during the sorting operation. In this case, if the hard rollers are used together, the material to be sorted will get scratched when passing through the roller gap, and if the soft rollers are used together, the above disadvantages do not exist.) This is not desirable because uneven accuracy will frequently occur. However, by implementing the present invention, such drawbacks can be eliminated.

On the other hand, in the present invention, these rollers are rotated in the same direction, or adjacent rollers are prevented from rotating toward the space between opposing rollers. In addition to effectively preventing jamming, the sorting work can be carried out while the objects to be sorted roll effectively between the rollers.

In this rotation method, in the arrangement of the rollers 1, 2, and 3 as shown in the example, when right rotation is used as A and left rotation is used as (1),
) 1-i, 2-i, 3-i, (2) 1 one shout 2-i, 3-

-C], 3-mouths are designed. In this drawing, rollers 1 and 3 are each three-stage rollers, and roller 2
Although the rollers 1, 2, and 3 are shown as having two stages of rollers, the rollers 1, 2, and 3 may each have three stages of the same shape, or the roller 2 may be a simple rod-shaped roller.

However, when a two-stage roller 2 is used as in this example, different sorting dimensions A, b, c, and d can be obtained at four locations, and effective sorting is possible. In this case, by appropriately increasing the number of stages or by arranging each stage to be located within each stage width between adjacent rollers 1 and 3, a larger number of sorting sizes can be efficiently obtained. Figures 2 to 4 show other examples; Figure 2 shows a roller with rod-like rollers 1 and 3 and a stepped roller 2;
3 is a stepped roller and 2 is a truncated conical roller, and FIG.
3 is provided in a tapered arrangement.

In each example, the adjacent rollers are alternately soft rollers and hard rollers, and their rotation directions are both rotated in the same direction, or each adjacent roller is rotated in the same direction. As in the previous example, the rollers are prevented from rotating into or toward the opposing rollers. In addition to the above examples, various combinations of these stepped rollers, rod-shaped rollers, and truncated conical rollers can be considered, and can be freely selected and implemented as appropriate. In the above embodiment, three sorting rollers are arranged, but if necessary, a desired number of sorting rollers can be arranged in a continuous and juxtaposed state for efficient implementation. As described above, the device of the present invention has one or more hard rollers and one or more soft rollers arranged in parallel, respectively, and each roller is combined with a stepped roller and a rod-shaped roller, or a combination of stepped rollers and a pair of stepped rollers. The stepped rollers may be arranged in such a direction that the distance between them gradually increases in the direction of movement of the objects to be sorted, and both may be made to rotate in the same direction. Since the rollers are rotated between adjacent rollers without rotating inward between the opposing rollers, efficient sorting is possible within a short distance.
Moreover, the objects to be sorted are less likely to be damaged, and moreover, the objects to be sorted roll well, allowing for highly accurate sorting.

Furthermore, by appropriately increasing the number of rollers, the sorting process can be carried out in a short time and efficiently, and at the same time, the apparatus can be made compact.

In addition, when implementing the present invention, when there are three or more sorting rollers and two or more of them rotate in the same direction, the rotation of the outer roller adjacent to the rotation direction side is controlled between the rollers rotating in the same direction. When the speed is gradually increased, the rolling motion of the objects to be sorted can be carried out more effectively and even more efficiently. Various materials can be used as the material to be sorted, but it is particularly suitable for sorting potatoes.
