Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention allows, for example, carrots, radishes and other vegetables to be transported such as long vegetables to be taken out from a storage section and sequentially transported to a measuring device in a subsequent step for automatic measurement and selection. In detail, the carrying-out device for sequentially carrying out the crops from the storage part and the sequential sending-out device for sending the crops sent out from the carrying-out device one by one in a predetermined posture to the weighing and sorting part in the next process. The present invention relates to a transportation device for sorting crops including a stationary transportation device.

[0002]

2. Description of the Related Art Conventionally, in the above-described crop sorting and conveying apparatus, a crop is stored by a conveyor which has locking projections formed at a predetermined pitch on the outer peripheral surface of an endless rotating belt from one side of a storage hopper. One by one is scooped up and placed on the locking projections and is carried out diagonally upward. During the transportation on the lower side of the transportation, the crops are placed one by one and moved up and down. A structure having a discharge tool to be sent to the process has been considered.

[0003]

However, in the above-described conventional structure, the discharging tool is vertically moved to discharge the crops one by one while the crops are continuously conveyed from the conveyor to convey the crops. Since it is a structure, in order to increase the transport efficiency, it is necessary to increase the driving speed of the discharging tool, but if this is done, the crop may be damaged, and there is the disadvantage that the driving speed cannot be increased unnecessarily. In addition, there is a possibility that two crops will be erroneously placed on the discharging tool, and one crop will not be surely placed one by one, and there is room for improvement in this respect as well. The present invention aims to eliminate the above-mentioned problems.

[0004]

According to the characteristic constitution of the present invention, in the transportation device for sorting crops described at the beginning, the upper crop mounting surface having substantially the same width as that of the transported crop has a transportation crop of the transported crop. A plurality of transporters configured in an inclined posture that is positioned downward as the transporting side of is arranged in parallel along the crop transporting direction,
In addition, a drive mechanism is provided for moving each carrier up and down at a predetermined pitch, and the drive timing is set so that adjacent carriers move up and down in a contradictory manner, thereby configuring the progressive-loading and carrying device, and terminating the transfer. That is, the carrier on the side is formed in a thin plate shape.

[0005]

With respect to the crops conveyed by the carry-out device, the placed crops are sequentially transferred to the conveyance body on the lower side of conveyance along the inclination thereof by the vertical movement motion of the conveyance body. At this time, since adjacent ones of the transporters move up and down in a contradictory manner, only the crops placed on one transporter move to the transporter on the lower side. Since the width is almost the same as the crop width, by repeating the transfer operation as described above a plurality of times, only one crop is placed on the carrier at the transport end portion. It is sent out one by one to the weighing and sorting section of the process. Moreover, since the transport body on the transport end side has a thin plate shape, the crops are placed on the transport body on the upper side of the transport body while the transport body on the transport end side drops downward almost at the same time. It is sent to the weighing and sorting section. As a result, it is possible to suppress the occurrence of defects such as a crop having an irregular shape, such as a substantially conical shape, which is generally sent to the weighing and sorting unit while rolling on the carrier and is weighed in an unstable oblique posture.

[0006]

[Effects of the Invention] Therefore, even when a plurality of overlapping crops are carried out from the storage section, the crops can be reliably delivered one by one to the weighing and sorting section in the subsequent process, and the weighing and sorting section can be sent out. Since the crops can always be sent out in a stable posture, the weighing accuracy is improved. In addition, compared with the case where the crops are released one by one while being placed and transported by the transport conveyor, even if the vertical movement speed of the transporter is set to a relatively high speed, the sorting and placing effect for each one is stable. Therefore, it is possible to improve the transport efficiency.

Is configured to be placed, and each of the transport bodies 21 is slightly inclined along the transport width direction so that the transported crops C overlapping with the transport are laterally displaced and placed one by one. is there.

In the progressive feeding device 3, the transported crop C is transferred to the transport body 21 on the lower side in the transport direction by the upward movement of the transport body 21 by the crop placing surface 21a in the inclined posture. The transfer target crop C is transported by sequentially repeating such transfer. At this time, since the transported crop C before being transferred to the transport body 21 moving downward is received and supported by the front surface of the next transport body 21, the separation is surely performed. Moreover, the width of the carrier 21 is C
