Description of the Related Art For example, in the case of weighing a product such as a packed product which has been previously weighed and packed, a weighing device in which a load cell as a weight detecting means is loaded with a carrying device such as a weighing conveyor is used. A carry-in conveyor is placed at one end of the weighing conveyor, while a carry-out conveyor is placed at the other end, and the goods that have been sent from the carry-in conveyor to the weighing conveyor and have completed weight measurement are required. According to the above, the sorting device discharges the non-quantitative product to the outside of the transport path, and then supplies it to the carry-out conveyor.

びこれを用いた計量装置を提供することにある。However, as described above, this type of weighing device measures the weight of the article while the article is being moved by the weighing conveyor, and therefore receives a weighing error due to aerodynamic forces such as lift. There is a problem of causing. In particular, as the conveying speed of the measuring conveyor increases, the lifting force also increases, and this measurement error increases. Further, also in the carry-in conveyor, if the posture of the article is not stable due to the lifting force, the measurement error in the measurement conveyor in which the article was sent in that state becomes large, and in the carry-out conveyor,
It adversely affects processing such as packaging in the next process. An object of the present invention is to provide a carrier device that can improve the stability of the posture of an article against an aerodynamic force such as a lift force generated during the carrier, and a weighing device using the carrier device.

A groove portion is formed which has an opening on the upper surface and extends in the transport direction, which generates a downward aerodynamic force to act. According to this configuration, the velocity of the air flow passing through the narrow groove is higher than the velocity of the air flow around the article,
Negative pressure is generated in the groove to generate a downward aerodynamic force (hereinafter referred to as downforce) on the lower surface of the article, thereby pushing the article in the direction of the groove and stabilizing the posture.

品の姿勢を安定させて搬送することが可能になる。In a preferred embodiment of the present invention, the transfer device is a belt type conveyor, and the transfer belt is a flat belt. The flat belt is more suitable for conveying the article in a stable posture than the round belt. However, in the case of a flat belt, the distance between the top plate (a part of the conveyor frame) on the lower side of the belt and the lower surface of the article becomes small, and therefore, an amount sufficient to generate a negative pressure between the article and the flat plate. It becomes difficult for the air flow to occur. Even then,
Since the groove can be provided and a sufficient amount of airflow can be introduced to effectively generate downforce, the posture of the article can be further stabilized and conveyed.

According to this configuration, since the posture of the article is stabilized, it is possible to improve the weighing accuracy, and further, it is possible to suppress light detection of the weighing value due to the downforce that reduces the lift generated when the article is conveyed at high speed. .

These rollers 12 and 13 have two flat belts 15 having a flat cross section. 16 are stretched in parallel. The driving roller 12 is driven by a motor 26 attached to a base 40 via a driving belt 27 to drive the two flat belts 15 and 16, and the flat belts 15 and 16 are conveyed along a conveying path. 50 is conveyed in the direction of arrow E. The conveyor frame 11, which is a member provided along the transport path, has a top plate 14 that covers below the upper traveling portions of the flat belts 15 and 16, and this top plate 14 has a top plate 14 shown in FIG.
Further, as shown in FIG. 1C, a groove portion 21 having a constant width and depth and extending in the transport direction E is formed.

The lifted force U shown in FIG. 1C acts mainly on the air flow flowing on the upper surface of the article 50 conveyed by, and the downforce D acts on the air flow flowing in the groove portion 21 on the lower surface. Make the downforce D larger than the lift U,
It is preferable that the lift U is completely canceled and the article is pressed toward the top plate 14, that is, toward the groove 21. In this way, the lift U is canceled by the down force D, and the posture of the article 50 on the flat belts 15 and 16 is stabilized. Further, with the cancellation or reduction of the lift U, the measurement value by the weight detection device 30 is prevented from shifting to the smaller side, and the measurement accuracy is also improved. Where the ceiling 14
Since a force in the opposite direction to the down force D acts on the object, a weight value error of the article 50 due to the down face D does not occur.

In the figure, the groove portion 21 extending in the transport direction E has a constant depth and a wide width on the carry-in side (left side) and a narrow width on the carry-out side (right side). . The larger the cross-sectional area (the cross-sectional area) of the groove portion 21, the smaller the air flow velocity, and therefore the downforce D also becomes smaller.

It changes to become larger. As a result, even for an article 50 in which the head is likely to move up and down, there is no possibility of causing a sudden head lowering due to a large downforce immediately after being carried in to cause vertical rocking, and the head is gradually lowered, so that the posture is stabilized and the weighing is performed. Improved accuracy is achieved. Depending on the shape of the article 50, conversely, the groove width of the groove portion 21 may be smaller on the carry-in side and larger on the carry-out side.
