短縮化が図れる。Thus, the article supply box, the supply path,
Since the collective transport path and the aligned transport path are respectively provided in a slanted direction in the delivery direction, the article is in a state where it is likely to descend down the slant due to its own weight. It is possible to reduce the size and weight of the vibration source. Moreover, since the article supply box and the supply path, the supply path and the collective transfer path, and the aligned transfer path are provided so as to be directed in opposite directions, a width in the lateral direction is not required. Further, when the weight of the articles sent to the weighing box reaches a predetermined planned amount before reaching the predetermined amount, a signal is issued from the weighing means provided in the weighing box to prevent vibration of the article supply box and the collective conveyance path. Since the delivery of the articles from the collective transport path is stopped by blocking the output port of the collective transport path as well as stopping, the natural amount of the unexpected amount of the articles from the outlet of the collective transport path is stopped. Since it is possible to prevent the drop surely, it is not necessary to level the articles on the collective transport path unlike the conventional weighing device, and the length of the collective transport path can be made shorter than that of the conventional collective transport path. The size of the entire device can be reduced in combination with the reduction in size and weight of the vibration source and the fact that the width in the lateral direction is not taken. Further, as described above, the articles sent out from the supply path are aligned and conveyed with the collective conveyance path which is located below the supply path, has the delivery direction opposite to the delivery direction of the supply path, and is inclined in the delivery direction. Since it is received on the road, the articles sent out from the supply path are sent out in the direction of rising the inclinations of the collective conveyance path and the aligned conveyance path, so the acceleration applied to the articles sent out from the supply path is the collective conveyance path and the aligned conveyance path. Works toward the ascending direction, whereby the articles sent to the collective transport path and the aligned transport path stop at the place where they are received, and hardly move in the tilt direction. This does not require a means for constantly averaging the supply amount of articles in the supply path, and always automatically controls automatically. Therefore, a large amount of articles are sent from the supply path to the collective conveyance path and the aligned conveyance path. However, this has almost no effect on the amount of articles sent from the collective transport path and the aligned transport path to the weighing box, and therefore it is possible to send out a large amount of articles from the supply path to the collective transport path and the aligned transport path, and When the delivery of the articles sent to the weighing box by vibrating the transport path and the aligned transport path is stopped, as described above, the predetermined amount before the weight of the articles sent to the weighing box reaches the predetermined amount. When it reaches, the vibration of the article supply box and the collective transport path is stopped, and the delivery port of the collective transport path is blocked to stop the delivery of the article from the collective transport path. After stopping the delivery of articles, it is possible to reliably prevent an unexpected amount of articles from spontaneously dropping from the delivery port of the group transport path, and it is possible to deliver a large amount of articles, and vibration of the article supply box and the group transport path. Continues to vibrate even after stopping the product. When the articles are sent out one by one from the alignment conveyance path to the weighing box and the weight of the articles sent to the measurement box reaches a predetermined amount, the vibration of the alignment conveyance path is stopped and the alignment conveyance is performed. Since the delivery of articles from the road is stopped, the accuracy of weighing and the weighing time can be shortened.
