Description

  The present invention relates to a conveyor belt used for conveying fruits and vegetables.

  Patent Documents 1 and 2 disclose conveyor belts used in facilities for sorting and packaging fruits. The conveyor belt has a hair material planted on the entire surface thereof, thereby reducing the rolling of the fruit being conveyed and the vibration received from the surface of the conveyor belt, thereby reducing the damage to the fruit.

  However, this conveyor belt has not been sufficiently cushioned to reduce the drop impact of the fruit that has been sorted out. In addition, planting the bristle material over the entire surface of the wide conveyor belt is poor in workability, and the cost of the conveyor belt itself is high. Furthermore, when some of the bristle material is damaged, dirty, or the like, the entire conveyor belt needs to be replaced, which makes it expensive to maintain the conveyor belt.

  The conveyor belt 1 for transporting fruits and vegetables according to the present invention, for example, as shown in FIG. 1, is judged by a sorting machine 3 that sorts sugar content, size, presence or absence of scratches, etc., and transports the sorted fruits and vegetables 5 to the packaging position. Used to do. A plurality of conveyor belts 1 for conveying fruits and vegetables are installed at the fruits and vegetables discharge position.

  In the conveyor belt 1 for conveying fruits and vegetables of the present invention, a plurality of hair bundles 9 formed by bundling a plurality of bristle materials 7 are planted over the entire surface of the belt base 11, and the belt bases 11 are arranged in a plurality of rows in the running direction. It is divided into two.

  As shown in FIG. 1, the belt base 11 is a belt made of rubber or the like that is stretched around a conveyor pulley 15 and travels in a predetermined direction by a driving device (not shown) to convey the fruits and vegetables 5. The belt base 11 has a thickness that allows the bristle material 7 to be planted. The belt base 11 is divided in the running direction, and the divided belt base 13 (hereinafter referred to as the split belt base 13) is stretched in parallel at a predetermined interval. The length of the belt base 11, the number of divisions, and the width of the division belt base 13 are not particularly limited, and are appropriately designed according to the conveyance target and the conveyance path.

  In this embodiment, as shown in FIG. 2, an endless belt having a thickness of 15 mm and a belt length of 7 m is used as the belt base 11, and this is divided to form a split belt base 13 having a belt width of 15 mm. ing. The divided belt bases 13 are stretched in parallel to the conveyor pulley 15 with an interval of 5 mm. The split belt base 13 includes hair bundles 9 planted in a row in the longitudinal direction.

As shown in FIG. 2, the hair bundle 9 is formed by bundling a plurality of hair materials 7. As this bristle material 7, typically, a bristle made of chemical fibers such as nylon, polypropylene, polyvinyl chloride or the like can be used. The hair bundle 9 is planted perpendicularly to the split belt base 13 and fixed. The planting interval and the length from the surface of the belt base may be designed according to the fruits and vegetables 5 to be conveyed. For example, when transporting fruits and vegetables 5 that are relatively small and light, the interval is narrow (eg, 10 mm to 20 mm) and the length is short (eg, 30 mm to 50 mm) so that the fruits and vegetables 5 are not sandwiched between the hair bundles 9. ) Designed. On the other hand, when transporting fruits and vegetables 5 that are relatively large and heavy, the spacing is wide (for example, 20 mm to 30 mm) and the hair bundle 9 is long (for example, 50 mm to 100 mm) so that the drop impact of the fruits and vegetables 5 can be sufficiently absorbed. Is done. Further, the planting interval may be changed for each divided belt base 13.
The hair bundle 9 absorbs the drop impact of the discharged fruits and vegetables 5 and prevents the fruits and vegetables 5 being conveyed from rolling. The hair bundle 9 can be replanted according to dirt or damage.

  In this embodiment in which the object to be transported is a mandarin orange, bristles made of 65 polypropylenes are bundled to form a hair bundle 9, and the hair bundle 9 is planted and fixed to the divided belt base 13 at intervals of 20 mm. The length of the hair bundle 9 is 70 mm.

The conveyor belt 1 for conveying fruits and vegetables of the present invention is manufactured through the following steps.
(1) A necessary width of the belt base 11 is set based on the size of the fruits and vegetables 5 to be conveyed, and the belt base 11 is appropriately divided to prepare a divided belt base 13.
(2) A plurality of flock holes 17 are formed in the divided belt base 13 at a predetermined interval.
(3) A plurality of bristle materials 7 are prepared, and these are bundled to form a hair bundle 9.
(4) The bent hair bundle 9 is driven and fitted into the flock hole 17 together with the metal stopper 19 and planted.
(5) The above-described steps (3) and (4) are repeated to plant the hair bundles 9 in all the flock holes 17. Thereby, the divided belt base 13 in which the plurality of hair bundles 9 are planted is formed.
(7) The above-described steps (2) to (6) are performed on the other divided belt base 13 to form the conveyor belt 1 for conveying fruits and vegetables of the present invention.
The conveyor belt 1 for conveying fruits and vegetables according to the present invention is used by being laid over a conveyor pulley 15. When the divided belt base 13 is placed on the conveyor pulley 15, the hair bundles 9 may be uneven in the lateral direction.

  In the conveyor belt 1 for conveying fruits and vegetables according to the present invention, a belt base 11 is divided into a plurality of rows. Therefore, as shown in FIG. 3, when the discharged fruits and vegetables 5 land on the split belt base 13, the split belt base 13 bends independently, and a plurality of split belt bases 13 individually absorb the drop impact. Then, damage to the fruits and vegetables 5 can be prevented. In addition, when the divided belt base 13 or a part of the hair bundle 9 becomes dirty or damaged, only the split belt base 13 needs to be replaced, so that the replacement work is easy and the replacement cost can be reduced. .

  Moreover, the hair bundle 9 can be replanted. Therefore, when only the hair bundle 9 is soiled or damaged, it is not necessary to replace the divided belt base 13, and the maintenance cost can be reduced.

  As shown in FIG. 4, the conveyor belt for conveying fruits and vegetables according to the present embodiment may be one in which the split belt base 13a at the edge of the belt base 11 protrudes from the other split belt base 13b. The edge portion of the split belt base 13a is disposed so as to protrude from the other split belt base 13b by having both ends spanned over a large-diameter conveyor pulley 15a. In this conveyor belt for conveying fruits and vegetables, a step 21 is formed between the divided belt base 13a and the other divided belt base 13b at the edge, so that the fruits and vegetables 5 being conveyed can be prevented from falling.

  In addition, as shown in FIG. 5, the conveyor belt for conveying fruits and vegetables of this embodiment may be such that the divided belt base 13a at the end of the belt base 11 is less flexible than the other split belt base 13b. As the split belt base 13a at the edge, a material having a lower stretchability than the other split belt base 13b, a material thicker than the other split belt base 13b, or a short one can be used. By spanning the split belt base 13a at the end together with the other split belt base 13b to the conveyor pulley 15, an end split belt base 13a that is less bent than the other split belt base 13b is formed. This conveyor belt for conveying fruits and vegetables can prevent the fall of 5 fruits and vegetables being conveyed.
