Abstract

PROBLEM TO BE SOLVED: To properly perform inspection work and sorting work of the articles, by mounting and conveying the articles between a rotor of large diameter and a rotor of small diameter, and preventing the movement of the articles by difference in level, of the rotors, so that the articles of various sizes can be surely rotated. SOLUTION: In the case when it is necessary to correct the direction and the attitude of the fruit and vegetables placed between a rotor 24 of large diameter and a rotor 25 of small diameter, a rotating machine 6 is driven to rotate the rotors 24, 25 on which the fruit and vegetables A are placed. On this occasion, the transfer of the fruit and vegetables A in the longitudinal direction is prevented by the difference in level, of the rotors 24, 25, the fruit and vegetables A of large, middle and small sizes are rotated by the rotating force of the rotors 24, 25, and the direction and the attitude of the same are corrected. Further by projecting the lifting members 36,... upward, the direction of the elliptical fruit and vegetables A inserted between the rotors 24, 25, obliquely positioned or standed, can be corrected to a horizontal attitude, and the fruit and vegetables A placed between the rotors 24, 25 are conveyed in the lifted condition. Whereby the examining work and the sorting work can be properly performed.

Description of the Related Art Conventionally, as an apparatus for transporting fruit and vegetables such as that described above, for example, a number of rollers are arranged at predetermined intervals in a feed direction, and a driving force of a feed motor with a speed reducer is provided. Therefore, there is a roller conveyor that rotates each roller in the feeding direction and sequentially conveys the fruits and vegetables placed between the rollers in the feeding direction.

Since the fruits and vegetables are fitted, the fruits and vegetables are prevented from moving forward and backward (transfer), and the fruits and vegetables can be rotated (for example, about 180 degrees) by the rotational force of each roller. When conveying fruits and vegetables having a large outer diameter, the larger the outer diameter of the fruits and vegetables placed between the rollers is, the smaller the fitting amount becomes, and the fruits and vegetables are placed substantially horizontally between the rollers. Therefore, when each roller is rotated in the feed direction, the fruits and vegetables placed between the rollers move horizontally (transfer) in the feed direction, and there is a problem that the fruits and vegetables cannot be turned upside down. ing. In addition, if the rotation of the fruits and vegetables is insufficient (for example, about 180 degrees or less), the back side of the fruits and vegetables cannot be inspected,
There is also a problem that the work of inspecting the class of fruit and vegetables and the work of sorting by class are not performed properly.

For example, a synthetic rubber or the like is provided at a height position which is disposed on the front side of the inspection part a and the middle part of the front and rear inspection area and is pressed against the lower peripheral surfaces at the free ends of the rotating bodies 24 and 25. A rotation imparting belt 56, which is a member having a large resistance and has a width and a length that is pressed against the free ends of the rotating bodies 24 and 25, is stretched in parallel with the feeding direction. Rotation imparting belt 56
Are pulleys 57, 57 pivotally supported at the start end and the end,
The belt is stretched around a belt guide 58 provided at the upper center, and guides the intermediate portion of the rotation imparting belt 58 around the belt guide 58 in a slightly lifted state. At the time of reversal, the rotation imparting belt 56 is rotated at a high speed (more than the feed speed) in the direction coinciding with the circling direction of the rotating bodies 24 and 25 by the driving force of the rotation motor 59 with the speed reducer directly connected to the terminal side pulley 57. Or by rotating the rotating bodies 24 and 25 pressed against the rotation imparting belt 56 while rotating the rotating bodies 24 and 25 at a low speed or in a direction opposite to the circumferential direction, thereby rotating the rotating bodies 24 and 25 on the small diameter side. Due to the peripheral speed difference generated between the peripheral surface and the large-diameter-side peripheral surface, the large, medium and small fruit vegetables A are turned upside down (for example, 180 degrees) in the front and rear direction in the same region. As another rotation method, as shown in FIG.
The rotation member 2 is attached to the rotation applying pad 60 formed of the same member as
As described above, the fruits and vegetables A placed between the rotating bodies 24 and 25 can be turned upside down by making the orbits 4 and 25 circulate in the feed direction while being pressed against each other.

When it is necessary to correct the orientation and posture of the fruit or vegetable A placed between the rotating bodies 24 and 25, the rotating machine 6 is driven to rotate the fruit or vegetable A on which the fruit or vegetable A is placed as shown in FIG. By rotating the bodies 24 and 25, the fruits A
Is prevented from moving in the front-rear direction, the large, medium and small fruit vegetables A are rotated by the rotational force of the rotating bodies 24 and 25, and the orientation and posture can be corrected. The lifting members 36 are projected upward to fit between the rotating bodies 24 and 25, or the oblique or upright elliptical fruit and vegetable A is corrected to a horizontal posture and placed between the rotating bodies 24 and 25.
