Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to fruit and vegetables such as oranges, apples, watermelons, pears, persimmons, peaches, potatoes, ball balls for tennis, soccer, baseball, table tennis and the like, or other approximate balls. The present invention relates to a keyboard-type transport device used for transporting an article having a shape.

[0002]

2. Description of the Related Art Conventionally, an apparatus for transporting and distributing articles as described above (Japanese Patent Application Laid-Open No. Sho 63-171691) attaches a cross member which constitutes a support means to a chain provided on a transport path, and provides a horizontal member. A movable cross member is rotatable from a horizontal position to an upper position via a pivot on one side of the member, and the cross member is overlapped, and the cross member is provided above the chain.

[0003] On both sides of the movable cross member, lids or elements that are opened upward are continuously provided, and shafts formed at both ends of the rollers are inserted into the lids or elements so that the rollers can move up and down in parallel. I support it.

When an article is discharged from a roller, a flap connected to the movable cross member is pushed up by a fixed cam, and in order to tilt and rotate the roller, gear-shaped wheels are formed at both ends of the roller. It has an extremely complicated structure in which rotation is given by contact.

[0005]

However, in the apparatus described above, the roller is a two-sided support supported by shafts at both ends thereof, and is movable up and down by a lid or an element. The rollers vibrate due to the vibration, and it is difficult to convey the article in a stable posture, so that the article cannot be conveyed at high speed.

Since there is a cross member and a chain at the lower part of the roller, a cam for applying a rotational force to the roller cannot be formed on the lower surface of the roller, and gear wheels are formed at both ends of the roller. Is indispensable, and the structure of the roller is complicated.

At the time of release, the article comes into contact with the groove for engaging the wheel or the lid or the element located below the slope, thereby damaging the surface and skin of the article such as apple, persimmon, etc. Product value is lost.

Further, when an article comes into contact with the above-mentioned wheel at the time of discharge, resistance is exerted on the wheel to flow down, the flowing direction becomes unstable, and there is a problem that stability is lost at a predetermined position and in a predetermined direction.

When the article is discharged from the roller, the flap connected to the movable cross member is pushed up by the fixed cam to move up one end of the roller. Indeed, since the article is in a state of jumping up, there is no stability in the discharging position and direction, and high-speed processing cannot be performed.

Further, if the inclination of the fixed cam is made gentle, the distance over which the roller is inclined becomes long, so that the starting point of discharge of the article in the transport direction is not determined, and it is difficult to discharge the article in a predetermined position and direction. There is a problem that high-speed processing cannot be performed because of the stability.

In view of the above problems, the present invention mounts and conveys articles on support rollers arranged in a keyboard shape, and rotates the support rollers on which the articles are mounted up and down or forward and reverse.
It is an object of the present invention to provide a keyboard-type transport device capable of easily performing an attitude control and an ejection operation of an article and improving transport efficiency and transport capability.

[0012]

According to the first aspect of the present invention,
The end of the support roller is rotatable on the endless belt erected on the transport path, and is vertically rotatably supported in a horizontal position and a discharge position perpendicular to the feed direction. It is characterized by a keyboard-type transport device in which a large number of keyboards are arranged in a keyboard direction in a feed direction at predetermined intervals on which the articles are placed.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, a rotating means for rotating the support roller on which the article is placed forward and reverse with respect to a feed direction is provided on the transport path. A keyboard-type transport device.

According to a third aspect of the present invention, there is provided a keyboard having, in addition to the configuration of the first aspect, a discharge means for vertically rotating a support roller on which the article is placed in a release position on the transport path. It is a mold conveying device.

[0015]

According to the first aspect of the present invention, since the article is placed on the horizontal supporting roller attached to the endless belt and moves horizontally in the feed direction, the keyboard-type conveying apparatus according to the first aspect of the present invention can move the article placed on the supporting roller. The placement position and the placement interval are not restricted, and a large number of articles can be placed and transported at arbitrary intervals. In addition, by rotating the support roller on which the article is placed in the normal or reverse direction, the direction and posture of the article placed on the support roller can be changed. In addition, by rotating the support roller on which the article is placed to the release position, the article placed on the support roller can be released at an arbitrary position.

According to the second aspect of the present invention, in addition to the operation of the first aspect, the keyboard-type transport device drives the rotating means to rotate the support roller on which the article is placed in the normal or reverse direction. The orientation and the posture of the article placed on the can be changed arbitrarily.

According to the third aspect of the present invention, in addition to the operation of the first aspect, the keyboard-type transport device drives the discharging means to vertically rotate the supporting roller on which the article is placed to the discharging position. An article placed on the support roller can be discharged at an arbitrary position.

[0018]

According to the present invention, the articles are placed on the support rollers arranged in the shape of a keyboard and are conveyed. Each of the articles can be successively placed in a state of being close to or arbitrarily spaced at an arbitrary interval, thereby improving transport efficiency and transport capacity.

In addition, since the support roller on which the article is placed is rotated forward and backward by the rotating means, the direction and posture of the article placed on the support roller can be arbitrarily changed.
Posture control such as aligning the orientation and posture of the article or changing the article to a posture suitable for release can be easily performed. For example, by visually observing the entire article placed on the support roller with an operator's eyes or taking an image with an imaging camera, discoloration, decay, degraded parts such as damage can be ensured even on a part of the peripheral surface of the article. The quality inspection and sorting work of the entire article can be performed accurately.

Further, during the transportation, the supporting roller on which the article is placed is rotated up and down by the releasing means, so that the article placed on the supporting roller can be released at an arbitrary position. Operations for transporting articles such as distribution, supply, and sorting can be stably performed.
