Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an article display reading device used for optically reading a bar code or the like displayed on an article.

Prior Art Conventionally, as shown in FIG. 4, a scanner 2 is placed on one side of a conveyor 1, and articles 3 are
There is an apparatus that optically reads display contents such as a bar code 4 during the process of conveying the bar code.

Problems to be Solved by the Invention However, such items cannot be read unless the barcode 4 is directed toward the scanner 2 and the article 3 is conveyed. Therefore, each time this reading error occurs, it is necessary to return the article 3 and correct the orientation.

This idea was created in consideration of these points,
It is an object of the present invention to provide a display reading device for an article that can reliably read display contents regardless of changes in the orientation of the article.

Means for solving the problem This invention consists of an incoming conveyor 5 and an outgoing conveyor 6.
A rotary table 7 is provided between the conveyor 5 and the rotary table 7, the scanner 2 reads the display contents of the article 3 carried into the rotary table 7 from the carry-in conveyor 5, and the article 3 is transferred to the carry-out conveyor 6 by the carry-out body 14.

Therefore, the article 3 on the carry-in conveyor 5
Even if the orientations of the objects 3 and 3 are uneven, the display contents of the object 3 will be directed toward the scanner 2 at least during one revolution of the turntable 7.

Embodiment An embodiment of this invention will be explained based on FIGS. 1 to 3. A frame 8 that holds a rotary table 7 driven by a motor (not shown) is provided between an input conveyor 5 and an output conveyor 6 that are arranged orthogonally to each other. The ends of the belts 9 of the conveyors 5 and 6 protrude into the frame 8 from the lower side of the upper plate 10 of the frame 8, so that there is not much space between the peripheral edge of the rotary table 7 and the belts 9. ing. Further, guides 11 and 12 are arranged on both sides of the end of the conveyor 5 to bring the articles 3 to the center. On one of the guides 11, a guide 13 is formed continuously around the outer periphery of the rotary table 7.

Further, the frame 8 is provided with a scanner 2 and a delivery body 14 that moves in a direction matching the conveyance direction of the delivery conveyor 6. One side of this carrying body 14 has a column 16 that is pushed into a guide groove 15 formed in the upper plate 10 of the frame 8, and the lower end of this column 16 is fixed to a carrier 17 as shown in FIG. There is. This carrier 17 is held slidably along the guide groove 15. Further, the frame 8 is provided with a motor 18 which is a drive unit and can freely rotate in forward and reverse directions, and pulleys 19 located at both ends of the guide groove 15.
A pulley 20 is directly connected to the pulley 8. Pulley 20
The wire 21 wound around is changed direction by a pulley 19, and its both ends are fixed to a carrier 17.

In such a configuration, when the article 3 is placed on the carry-in conveyor 5 at a predetermined timing, the article 3 is sent to the rotating table 7. As shown in FIG. 1, even if the barcode 4 of the article 3 faces directly opposite the scanner 2, the barcode 4 can be reliably read by the scanner 2 because the turntable 7 rotates. Then, the carry-in conveyor 5 receives a reading completion signal from the scanner 2.
stops, and then the motor 18 rotates back and forth. By rotating in one direction, the delivery body 14 moves along the guide groove 15 together with the carrier 17, pushing out the article 3 on the rotary table 7 onto the delivery conveyor 6, and by rotating in the other direction, the delivery body 14 returns together with the carrier 17. do. At this timing, the cycle in which the carry-in conveyor 5 rotates is repeated again.

Note that the transport body 14 and the guides 11, 12, 13 are designed to avoid interference due to the following relationship.

Effects of the invention Since this invention is configured as described above, even if the displayed contents of the article are directed directly opposite to the scanner, the displayed contents of the article can be directed to the scanner by the rotational movement of the rotary table. This has the effect that the displayed contents can be read reliably.
