Therefore, the the attitude control and the discharge operation of the mandarin oranges A are facilitated to enhance conveyance efficiency and conveyance ability.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to, for example, fruit vegetables (eg mandarin oranges, apples, persimmons, pears, etc.), marine products (eg fish, shellfish, etc.), processed foods, electric products, mechanical parts, electronic parts. The present invention relates to a keyboard-type transfer device used for the operation of transferring placed objects such as parts and raw materials.

[0002]

2. Description of the Related Art Conventionally, as a general transport means for transporting a load such as the above-mentioned example, for example, a large number of load components are sequentially placed on a transport surface of a belt conveyor or a thrust conveyor and transported. There is also a method of carrying out the above, or a method of placing and carrying a large number of respective placed objects on respective receiving portions formed on the chain conveyor or the bucket conveyor.

[0003]

However, when the objects to be placed are conveyed by the above-described belt conveyor or thrust conveyor, the placement position and the placement interval are not regulated, and a large number of the respective articles to be placed are continuously conveyed. However, since the orientation and posture of each placed object placed on the conveyor are not uniform during placement and transportation, the orientation and attitude of each placed object must be aligned by the operator's hand. However, there is a problem that the work is troublesome.

On the other hand, in the case of carrying a placing object by a chain conveyor or a bucket conveyor, since the placing object is placed on each receiving portion formed on the conveyor, the direction and posture of each placing object are regulated. However, it is not possible to change the orientation and posture of each placed object. Moreover, since the intervals between the receiving parts are set in advance, it is not possible to change the mounting position and the mounting interval of the respective mounting objects, and the supply amount of the respective mounting objects at the intervals corresponding to the respective receiving parts of the conveyor. Since it is regulated, it is difficult to continuously mount a large number of each mounted object, and there is a problem that the transfer efficiency is lower than that of a belt conveyor or a thrust conveyor.

In view of the above problems, the present invention mounts and conveys a mounted object on each rotary member arranged in a keyboard shape, and vertically rotates or rotates forward and backward each rotary member on which the mounted object is mounted. By doing so, it is an object of the present invention to provide a keyboard-type transfer device capable of easily performing posture control and discharging work of a mounted object and improving transfer efficiency and transfer capability.

[0006]

According to the first aspect of the present invention,
On the transport side of the endless belt erected on one side of the transport path, one end side of each support shaft that is pivotally supported by each of the plurality of rotating bodies with respect to one side edge of the endless band is orthogonal to the feeding direction. The supporting shafts are arranged on the rotating bodies at predetermined intervals so that the supporting objects are mounted on the rotating bodies, and the supporting shafts are mounted on the rotating bodies. It is characterized in that it is a keyboard-type transfer device which is mounted so as to be vertically swingable in a horizontal posture in which it is placed and in a discharge posture in which the placed object is discharged.

[0007]

In the keyboard-type carrier according to the first aspect of the present invention, the object placed on each rotary body is placed on each rotary body attached to the endless belt and horizontally moved in the feed direction. The placement positions and placement intervals of the figurines are not restricted, and a large number of the respective placement objects can be placed and conveyed at arbitrary intervals. In addition, by rotating each rotating body on which the mounted object is placed to the ejection posture, the mounted object placed on each rotating body can be ejected at an arbitrary position. Further, by rotating each of the rotary bodies on which the mount is placed by the rotating means in the forward and reverse directions, the orientation and the posture of the mount placed on each of the rotary bodies can be changed.

[0008]

According to the present invention, since the mounting object is placed and conveyed on each of the rotating bodies arranged in a keyboard shape, the mounting position and the mounting interval of the mounting object are regulated as in the conventional example. Instead, it is possible to continuously mount a large number of each mounted object in a state in which they are close to or apart from each other at an arbitrary interval, and it is possible to improve the transfer efficiency and transfer capability. In addition, by rotating each rotating body on which the mounted object is placed to the discharge posture, the mounted object placed on each rotating body can be discharged at an arbitrary position, for example, distribution, supply, and selection. It can be used for carrying work such as.

Further, by rotating each of the rotary bodies on which the mount is placed by the rotating means in the forward and reverse directions, the orientation and posture of the mount placed on each of the rotary bodies can be arbitrarily changed.
During transportation, align the orientation and posture of the placed object,
The placement object can be changed to a posture suitable for discharge, and the posture control of each placement object can be easily performed. For example, by visually inspecting the entire placed object placed on each rotating body with an operator's eyes or by taking an image with an imaging camera, there is an altered part such as discoloration, decay, and damage on a part of the circumferential surface of the placed object. However, it can be surely found, and the quality inspection and selection work of the entire placed object can be performed accurately.

Are pressed against the reversing belt 44 and rotated in one direction, so that each mounting roller 25 ...
The mandarin orange placed between can be turned upside down 180 degrees.

The illustrated embodiment is constructed as described above, and thereafter, a large number of each mandarin orange A is picked up by the fruit and vegetable sorter 1.
The operation when sorting ... by equal rank will be described. First,
As shown in FIGS. 2 and 3, the mounting rollers 25 forming the sorting conveyor 4 are moved back to the starting end of the feed side, and the rotary members 27 are axially supported on the orbiting chain 20.
.. and the locking claws 29a .. of the locking levers 29 ..
While rotating and returning to a horizontal posture, it is orbitally moved in the feeding direction. At the same time, a large number of each mandarin orange A ... brought in from the producer is placed on the cargo receiving conveyor 2, and each mandarin A ... carried by the cargo receiving conveyor 2 is arranged between the respective aligning rollers 13 of the respective aligning conveyors 3. Sequentially, the mandarin oranges A, which are placed between the aligning rollers 13 of the aligning conveyor 3 ..., are sequentially placed between the placing rollers 25 of the sorting conveyors 4 ... The mandarin oranges A are aligned and conveyed in a line on the peripheral surface of the central portion between the mounting rollers 25.

Next, at the image pickup positions set on the respective sorting conveyors 4 ... In response to the address reading of the respective placing rollers 25 ... by the respective address readers 39.
The front surface side of each mandarin orange A ... Mounted between 5 ... is imaged by the imaging camera 34, and the image data of the front surface imaged by the imaging camera 34 and the address data of each mounting roller 25 ... Correspondingly, it is stored in the judging device main body 37 of the equal class judging device 6. At the same time, as shown in FIG. 5, each mounting roller 25 on which each mandarin A is mounted is pressed against the reversing belt 44 of the front / back reversing machine 7 and is reversed at a speed higher than the moving speed of each mounting roller 25. The belt 44 is rotated in the feeding direction at a high speed, and the mounting rollers 25 pressed against the reversing belt 44 are rotated in the arrow direction, so that the oranges A mounted between the mounting rollers 25 are moved in the arrow direction.
