FIG. 11 is a configuration diagram of a transport test system according to a third embodiment;

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

The transport medium 10A has a shape that simulates transport objects such as coins, bills, tickets, and collected fruits and vegetables. A transport medium 10A shown in FIG. 1 simulates a bill, a ticket, or the like, and is formed in a rectangular sheet shape. Note that the transport medium 10A may be disc-shaped when simulating a coin. Further, the carrier 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) received by the conveying medium 10A. The degree of damage is damage that remains as a shape on the transport medium 10A (deformation, scratches, dents, defects, folds, curls, tears, and other external damage that appears externally, and internal damage that reduces the value of the transport object. ), and the damage (pressure, impact, etc.) received by the transport medium 10A, which does not remain as a shape on the transport medium 10A, is quantified. The damage measuring unit 1 is preferably a film-type (or element-type) pressure sensor or shock sensor in order to detect damage such as impact, contact, or interference on the surface of the medium 10A to be conveyed. Detects the level (degree) of impact or contact received.

In addition, when measuring the presence or absence of breakage of the conveying 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 or Low even if the wiring pattern is energized. On the other hand, if the wiring pattern is not disconnected, the output becomes 1 or High when the wiring pattern is energized. This makes it possible to measure the presence or absence of damage (degree of damage) of the transport medium 10A.

Further, when measuring the impact or the like received by the conveying medium 10A, the damage degree measuring section 1 may be a strain gauge. For example, when the transport medium 10A collides with a transport hindrance factor on the transport path and is bent, the strain gauge outputs an electrical signal corresponding to the bending (distortion). This makes it possible to measure the strength (damage) of the impact received by the transport medium 10A. If the strain gauge shows different values before and after the conveyed test medium 10 is conveyed, it can be detected that the conveyed test medium 10 has internal damage or the like that does not appear externally.

As described above, according to the conveyed test medium 10 having the minimum configuration, it is possible to inspect whether or not the conveyed object is damaged on the conveying path.

Further, the transport test system according to the minimum configuration includes the transport test medium 10 , a transport device having a transport path for transporting the transport test medium 10 , and a terminal device for receiving measurement results from the transport test medium 10 . Therefore, it is possible to inspect whether or not there is any damage to the object to be conveyed on the conveying path.

Further, in the transportation test method according to the minimum configuration, one or more of the transportation test media are transported on a transportation path, and at least one of the degree of damage received from a transportation hindrance factor on the transportation path and interference between the transportation test media. Measure one. Therefore, it is possible to inspect whether or not there is any damage to the object to be conveyed on the conveying route.
