Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for selecting and conveying crops, such as carrots, radish and other root vegetables, which are successively placed and conveyed and then sent to the next step in a predetermined posture. Is equipped with a carry-out section for sequentially placing and carrying out the conveyed crops from the storage section, and a sequential feeding placement and conveying apparatus for sending out the conveyed crops sent from the carrying-out section one by one in a predetermined posture to the next process. The present invention relates to a transportation device for sorting crops.

[0002]

2. Description of the Related Art In the above-mentioned crop sorting and conveying apparatus, conventionally, in the above crop sorting and conveying apparatus, conventionally, for example, locking projections are formed at a predetermined pitch on the outer peripheral surface of an endless rotating belt to cover the crops. One in which the transported crops are sequentially placed and locked by the respective locking projections in a horizontal posture and transported one by one, or over a pair of left and right endless rotation bands,
There has been considered a structure in which rollers that are freely rotatable at a predetermined pitch are supported and one crop is placed between each roller in a horizontal position and conveyed.

[0003]

In the conventional structure as described above, the crops are sequentially placed and transported one by one to measure the weight and length of the crops, to automatically sort and sort based on the measurement results, and the like. It is sent to the work process to enable automatic sorting of this type of crop.

However, in the above-mentioned conventional structure, it is not always the case that the crops are surely placed and guided one by one in the predetermined posture between the above-mentioned locking projections and the respective rollers. There is a high possibility that troubles such as a case where two or more pieces are placed on the protrusion or a case where the crop is not placed are generated,
Further, in the latter conventional structure, there is a great possibility that the crop is placed over a plurality of rollers and the like.
There is a drawback that the device cannot be surely placed and conveyed one by one at a predetermined pitch, and moreover, since the crops are conveyed while being placed along the conveyance width direction, the device becomes large in size, There was room for improvement.

The object of the present invention is to solve the above-mentioned disadvantages,
It is an object of the present invention to provide a crop sorting and conveying device that can reliably and efficiently send out crops one by one without increasing the size of the device.

[0006]

According to a characteristic configuration of the present invention, in the transfer device for sorting crops described at the beginning, the sequential feeding / placement transfer device is transferred in a direction substantially orthogonal to the transfer direction of the unloading device. A first lateral feed section for placing and carrying the crop, a vertical feed section for placing and carrying the crop in a direction along the carrying direction of the carry-out apparatus and a carrying direction of the carry-out apparatus connected with the vertical feed section. An upper side having a width substantially the same as the width of the transported crop, which is configured so as to form a U-shaped transportation path in plan view by the second lateral feed section that places and transports the transported crop in a direction substantially orthogonal to A plurality of conveyors each having a crop mounting surface arranged in a slanted position, which is located downward toward the lower side in the conveying direction of the conveyed crop, are arranged in parallel along the conveying direction of the conveyed crop, and each conveying body is predetermined. With a drive mechanism that moves up and down at a pitch, In that each carrier to each other have configured a contradictory manner the set driving timing so as to be moved up and down the first and second lateral feeding section each contact.

[0007]

In each of the transverse feed sections, the respective transporters move up and down, and the crops are transferred while the mounted crops are sequentially transferred to the transporter on the lower side by the tilted posture product placement surface of the transporters. Move on. Since the width of the carrier is almost the same as the width of the crop, the crops that are vertically stacked are collapsed and leveled by repeating the feeding operation as described above. Only individual crops are placed. As a result, even when a plurality of crops to be conveyed are superposed and sent in from the superior side of conveyance, one piece is always sent to the next step at the end of the conveyance. In addition, the vertical drive of each carrier only needs to consider the timing of movement of adjacent ones, and a simple drive structure is sufficient. Moreover, since the horizontal feeding section and the vertical feeding section form a U-shaped transportation path in a plan view, the transported crops can be carried in and out from the good side of the transportation in a posture along the longitudinal direction. Even if the width of the front and rear of the machine is set to be narrow, the conveyed crops with the conveying direction of each transverse feed section can be conveyed in the horizontal posture, so the whole posture should be rationalized. The transport path can be set to be short, and the above-described single feeding operation is executed in two stages, so that separate feeding for each one is ensured.

[0008]

Therefore, by reasonably improving the structure, it is possible to reliably feed the conveyed crops one by one to the succeeding process without shortening the conveying path and reducing the conveying width, and without increasing the size of the apparatus. We have come to be able to provide what we can.
