BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to the drawings. The brush mat 3 is integrally formed of rubber or synthetic resin, and the brushes 2 are arranged on the surface of the mat 1 so that the brushes 2 project at regular intervals. Molding of such a brush mat 3 is performed using a molding die. The mat 1 is set to have a width and shape corresponding to the size of the roller 5 around which the mat is wound, and the thickness and length B of the brush 2 and the arrangement interval are appropriately set according to the molding material and the like. Each brush 2 has a thick base on the mat 1 side and a thin tip. Further, this tip surface can be formed as a flat surface P or a spherical surface R (FIG. 2).

Each brush 2 of this brush mat 3 has an inclination angle A in a certain direction. The length B may be set to be a constant length over the entire surface of the mat 1 (FIG. 1), or may be set to be gradually shortened in the inclination direction (FIG. 5), and further lengthened in the inclination direction. Can be set (FIG. 6). It is also possible to combine the inclination direction and the length direction of the brush 2 (FIG. 7).

Mainly referring to FIG. 2, the brush mat 3
The shape of each of the brushes 2 can be shaped like a simple conical shape G, but can also be shaped like a two-step conical shape H in which the angle of the conical shape is changed into two steps. or,
It is also possible to form a stepped shape K having a different diameter by forming a step portion in the middle of the base diameter of the brush 2 and forming the tip portion diameter small. Further, the cross-sectional shape of each brush 2 is formed into a circular shape L, a flat elliptical shape M along the front-rear direction of the roller shaft 4, or a flat elliptical shape N along the rotation direction of the roller shaft 4. You can also

As described above, in each brush 2, the diameter of the base portion on the side of the mat 1 is made large and the diameter of the tip portion side is made small to form a die-cutting gradient at the time of molding, thereby facilitating die-cutting. Thus, the rigidity of the waist of the brush 2 can be enhanced, and the elasticity or flexibility of the tip can be maintained to enhance the brushing effect.

The brush mat 3 thus set,
The brush rollers 6 and 7 are formed by winding them around the outer peripheral surface of the cylindrical roller 5 and adhering them with an adhesive or the like (FIG. 2). The inclination direction of the brush 2 is substantially along the direction of the roller shaft 4.
Molding of the brush mat 3 as described above is simple because it is performed by molding, and the strength of the brush mat 3 can be increased because the brushes 2 are arranged in a single and independent standing posture on the surface of the mat 1 at regular intervals. Since the diameter of each brush 2 can be increased, it is possible to reduce the amount of dust and the like that are wound around or caught on the brushes 2, and to easily clean the brush roller. The winding edge 10 of the brush mat 3 wound around the outer peripheral surface of the roller 5 can be formed in parallel with the direction of the roller shaft 4 and joined as shown in FIG.
Further, as shown in FIG. 9, the roller shaft 4 may be inclined and formed into a spiral shape, or further, as shown in FIG. It is possible to reduce the opening, peeling, and the like of the wound edge 10 part.

By arranging such brush rollers 6 and 7 in parallel and transmitting the rotation, the brush rollers 6 and 7 are arranged.
When the fruit C is placed on the upper surface of the space, the fruit C is moved E in the inclination direction of the brush 2 while being rotated by frictional contact of the brush rollers 6 and 7 with the brush 2. In the form in which the brush rollers 6 and 7 are sequentially long on the inclined side of the brush 2 as shown in FIG. 7, the transfer force of the brush 2 in the inclined direction and the brush 2
The conveyance direction E of the fruit can be determined by the difference from the transfer force due to the inclination angle D of the rotation surface of the fruit.

In FIGS. 3 and 4, a weight sizer 8 for fruit selection is provided below one end of a pair of left and right brush rollers 6 and 7.
Is provided, the fruits C fed out from the ends of the brush rollers 6 and 7 are received on the respective sorting trays 9 and conveyed F to be weighed, and the respective sorting trays 9 are turned over to predetermined weight sorting positions. The fruit C is discharged. The end portion of the other brush roller 7 is formed to be shorter than the brush roller 6, and the selection tray 9
It is configured to smoothly supply the fruit C to the upper surface. In this weight sizer 8, a sorting tray 9 is arranged so as to be capable of tipping over and attached to a chain 11 that is spanned between sprockets 12 mounted on the front and rear of a sorting frame 13. Reference numeral 15 is a supply hopper that allows the supply port 16 to be seen above the starting ends of the brush rollers 6 and 7.

As described above, the brush rollers 6 and 7 are provided in the fruit supply stroke portion of the fruit sorting line such as the weight sizer 8. The brush rollers 6 and 7 are arranged side by side with the weight sizer 8 in the lateral direction. It may be arranged in a plurality of lines. A fruit can be conveyed and supplied by a shooter or the like onto the supply hopper 15 or the starting ends of the brush rollers 6 and 7.
In addition, a plurality of such brush rollers 6 and 7 are arranged in parallel with the weight sizer 8 to feed the fruits longitudinally in the direction of the roller shaft 4 while feeding the fruits laterally, and to distribute and feed to each weight sizer 8 line. You can also do it.
