The result of the weighing is stored in the control unit 106, and the weighed item is supplied to the downstream endless belt 107 which is wider and circulates in the horizontal direction. As shown in FIG. 15, a plurality of sets of wiper means 108a, 108
are provided, for example, the wiper means 108a and 108b are rotatably provided at predetermined angles via fulcrums 110a and 110b in response to a command from the control unit 106 . .

On the other hand, these wiper means 108a,
8b, 109a, 109b,..., A chute 1 for receiving the goods shaken off by the respective wiper means.
20 are arranged correspondingly, and below the container 121
Etc. are set.

In the transport device 100, when the motor 102 is driven, the marine products and the like in the storage unit 101 are transferred to the endless belt 10
3 and 104, are transported upward in two rows while being locked to the transport plates 105, 105, weighed at upper horizontal positions, and then transferred onto the endless belt 107. When traveling on the endless belt 107, the article is shaken to the side by the action of any one of the wiper means that operates according to the weighed result, and is stored in the lower container 121 or the like through the chute 120. Is done. Thereby, the storage unit 10
Items such as marine products stored in 1 are sorted and sorted to a weight within a predetermined range. It should be noted that the operation of a pair of left and right wiper means, for example, wiper means 108a, 108b,
Set to shake off the items of the weighed result within the same range,
In addition, if the chutes corresponding to these are merged, articles in the same range can be accommodated in one container.

By the way, when articles are conveyed by the endless belt as described above, the articles are dropped to the right and left by the wiper means, so that the number of conveying paths cannot be increased beyond two and the processing capacity cannot be increased. Has limitations. In addition, in a portion for picking up an item from the storage unit 101, the transport plate 10 is used.
There is a case where a plurality of articles are locked to 5, 105. In order to accurately weigh individual articles, the transport plate 105 is required.
Must be dropped manually by hand. Therefore, the number of hands required when a large number of the transfer devices 100 are installed is enormous. In addition, the transfer device 10
In the case of 0, the rounded article cannot be transported because it easily rolls.
