While one side is transferred to the second conveyor unit 33, the other side of the conveyed product 11 is transferred to the guide conveyor 34, and the conveyed product 11 is conveyed downstream in the conveying direction by the second conveyor unit 33 and the guide conveyor 34.

The guide conveyor 34 has a small horizontal separation distance W1> W2 with respect to the second conveyor unit 33 from the upstream side to the downstream side in the transport direction, and the second conveyor unit from the upstream side to the downstream side in the transport direction. Since the vertical separation distance with respect to 33 is large such that H1 <H2, the other side of the conveyed article 11 placed on the guide conveyor 34 is one of the conveyed articles 11 placed on the second conveyor unit 33. With the side as a fulcrum, it gradually rises, and after the conveyed article 11 has risen in the vertical direction, it is inverted so as to incline with respect to the vertical direction opposite to the first conveying posture.

Inclined conveyor of the second conveyor unit 33
The one side 12 of the conveyed article 11 reversed by 65 is supported so that the other side 12 faces upward and the side conveyor 66 conveys the conveyed article 11.
Supporting the lower edge 13 of the article 11, one side of the article 11 is high and the other side is low in the direction intersecting the conveyance direction, and one surface 12 of the article 11 opposite the other surface 12 is upward. And a second transporting position facing the front side, and the second transporting position is used for transporting downstream.

At the position downstream of the guide conveyor 34 of the second conveyor unit 33, while the conveyed article 11 is being conveyed, the bar code reader 92 of the second reading device 37 causes the other surface 12 of the conveyed article 11 to face upward. If the bar code 14 is displayed, scan the bar code 14.

From the end of the second conveyor unit 33, the conveyed product 11 is sent to the sorting conveyor 95 of the sorting section 24, and while the conveyed product 11 is conveyed by the sorting conveyor 95, the first reading device 36 and the second reading device. In accordance with the reading result at 37, the assortment means branches the conveyed article 11 and sends it to each assorting section 96. And

The conveyed article 11 can be reliably reversed by the guide conveyor 34 without affecting the reversal of the posture of the conveyed article 11.
For example, if the guide conveyor 34 is configured only with guides that do not convey the conveyed article 11, friction occurs between the conveyed articles 11 and the guides, and therefore the conveyed article 11 cannot be reliably inverted depending on the type of the conveyed article 11. There is a possibility that the transported object 11 may rotate in the transport direction. Therefore, by using the guide conveyor 34 that transports the transported object 11, the effect of friction can be prevented and the transported object 11 can be reliably inverted.

Further, the distance between the guide conveyor 34 and the second conveyor unit 33 in the horizontal direction from the upstream side to the downstream side in the conveying direction becomes small as W1> W2, and the second distance from the upstream side to the downstream side in the conveying direction becomes small. Since the vertical separation distance with respect to the conveyor unit 33 is so large as H1 <H2, the conveyed article 11 can be reliably inverted under these two conditions.

Moreover, the transport time of the article 11 from the upstream end to the downstream end of the guide conveyor 34 in the transport direction, and the upstream end to the downstream end in the transport direction of the section where the guide conveyor 34 of the second conveyor unit 33 is provided side by side. Since the conveyance times of the conveyed objects 11 up to are matched, even if the guide conveyor 34 is three-dimensionally inclined with respect to the second conveyor unit 33, the guide conveyor 34 and the second conveyor unit 33 cause It is possible to eliminate the difference in the conveyance speed of the conveyed object 11 and to reliably reverse the conveyed object 11 without rotating the conveyed object 11 in the conveying direction.

Further, a reading device equipped with the conveyed product reversing device 35.
According to 23, the first reading device 36 reads the one surface 12 of the conveyed object 11 conveyed in the first conveyance posture by the first conveyor unit 32, and the second conveyance posture by the second conveyor unit 33. The second surface 12 of the object 11 to be conveyed by the second
Since it is read by the reading device 37, it is possible to reliably read both sides of the conveyed product 11 even when the conveyed product 11 is continuously conveyed in the conveying direction.

The guide body is a guide conveyor.
Not limited to 34, depending on the type of the conveyed object 11, the conveyed object 11 is not driven to be conveyed unlike the guide conveyor 34, and for example, a roller conveyor in which a plurality of rotatable rollers is rotatably arranged along the conveying direction, or a plate. The conveyed object 11 can be inverted by using a rod, a pipe, a wire rod, or the like for guiding. In this case, the structure can be simplified.

Further, the first conveyor unit 32 conveys a product to be conveyed.
1st conveyance posture and 2nd conveyor unit which conveys 11
With the second transport posture in which the transport object 11 is transported by 33, the transport direction can be inverted with respect to the vertical direction, so that the transport of the transport object 11 by the guide conveyor 34 can be easily and reliably performed with a simple configuration. However, even when at least one of the first conveyor unit 32 and the second conveyor unit 33 is provided horizontally, if the guide conveyor 34 is set in accordance with the case, the first conveyor unit 32 to the second conveyor unit It can be configured such that the conveyed article 11 sent to 33 is reversed while being conveyed.
