An example of the minimum configuration of the present invention will be described with reference to FIG.
FIG. 1 is a configuration diagram of a transport test medium 10 according to a minimum configuration example of the present invention.
As shown in FIG. 1, the conveyance test medium 10 includes a conveyance medium 10A that is conveyed along a conveyance path (not shown), and a damage degree measuring section 1 that is provided on the conveyance medium 10A and measures the degree of damage to the conveyance medium 10A. , is equipped with.

The conveyance medium 10A has a shape that simulates objects to be conveyed, such as coins, banknotes, tickets, and collected fruits and vegetables. The conveyance medium 10A shown in FIG. 1 simulates a banknote, a ticket, etc., and is formed in a rectangular sheet shape. Note that the conveyance medium 10A may have a disk shape when simulating a coin. Further, the conveyance medium 10A may be spherical when simulating fruits, vegetables, or the like.

The damage degree measurement unit 1 measures the degree of damage (damage value) that the transport medium 10A receives. The degree of damage refers to damage that remains on the conveyance medium 10A as a shape (external damage that appears on the outside, such as deformation, scratches, dents, chips, bends, curls, tears, etc.) and internal damage that reduces the value of the conveyed object. ) and the damage (pressure, impact, etc.) sustained by the transport medium 10A, which is not retained as a shape on the transport medium 10A, is quantified. The damage measurement unit 1 is preferably a film type (or element type) pressure sensor or impact sensor in order to detect damage such as impact, contact, or interference on the surface of the conveyance medium 10A. Detects the level (degree) of impact or contact received.

In addition, when measuring the presence or absence of damage to the conveyance medium 10A, the damage degree measuring section 1 may be formed with a predetermined wiring pattern. For example, if the transport medium 10A is torn and the wiring pattern is disconnected, the output will be 0 to Low even if the wiring pattern is energized. On the other hand, when the wiring pattern is not disconnected, when the wiring pattern is energized, the output becomes 1 or High. Thereby, it is possible to measure whether or not the transport medium 10A is damaged (damage degree).

Furthermore, when measuring the impact received by the conveyance medium 10A, the damage degree measuring section 1 may be a strain gauge. For example, when the conveyance medium 10A collides with a conveyance inhibiting factor on the conveyance path and is bent, the strain gauge outputs an electric signal corresponding to the bending (distortion). Thereby, it is possible to measure the strength (degree of damage) of the impact received by the conveyance medium 10A. Note that if the strain gauge shows different values before and after the transport test medium 10 is transported, it can be detected that the transport test medium 10 has suffered internal damage that is not visible on the outside.

In this way, according to the transport test medium 10 having the above-mentioned minimum configuration, it is possible to test whether or not the object to be transported is damaged on the transport route.

Therefore, it is possible to inspect whether or not the object to be transported is damaged on the transport route.

Further, the transport test method according to the minimum configuration includes transporting one or more of the transport test media on a transport path, and determining at least one of the degree of damage caused by transport inhibiting factors on the transport route and interference between the transport test media. Measure one side. Therefore, it is possible to inspect whether or not the object to be transported is damaged on the transport route.
