Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transporting a magnetic material such as a steel plate. In particular, the present invention relates to an apparatus for transporting samples for measuring the hardness of a magnetic plate such as a steel plate and the amount of a surface treatment film such as plating to a measuring device one by one. 2. Description of the Related Art Conventionally, in a magnetic material transfer apparatus for transferring a measurement sample to a measurement apparatus for measuring the hardness of a steel sheet or the amount of a surface treatment film such as plating, the steel sheet is cut into predetermined dimensions by shearing. After being punched out by a press to form a sample for measurement, the measurement samples are stacked at a predetermined location, automatically gripped by the measuring device, transported, and loaded into the measuring device. [0003] However, in the above-described conventional magnetic material transfer apparatus, when the stacked measurement samples are automatically transferred to the measurement apparatus, the measurement samples are surely transferred one by one. And the measuring device does not operate, or the thin sample is stacked and transported to the measuring device in a state of being stacked, and only one of the multiple samples is measured. There was a problem that an accurate measurement result could not be obtained, for example, it was processed as something that did not exist. SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and provides an excellent magnetic material transporting device that can reliably carry in a measuring device one by one when a plurality of magnetic materials are measured as a measurement sample.

[0005] In order to solve the above-mentioned problems, a magnetic material transfer apparatus according to the first aspect of the present invention is provided with a plurality of magnetized transfer tables provided on an endless conveyor chain. A magnetic body transporting means for attracting and transporting a magnetic body, a magnetic body moving means having an arm and a suction head provided on the arm, and a control device for controlling the operations of these magnetic body transporting means and the magnetic body moving means. A magnetic material transport device comprising: the control device drives a sprocket by a drive device to rotate the endless conveyor chain to transport the magnetic material, and the transport table that has completed transport contacts a switch. The driving device is stopped to stop the endless conveyor chain, and then the suction head provided on the arm of the magnetic body moving means is moved to a magnetic body. The arm is moved until it touches, and the magnetic body is sucked by the suction head and removed from the carrier, then the arm is moved a certain distance, and then a series of operations to release the magnetic body by releasing the suction by the suction head are controlled. Further, a photoelectric switch is provided at the end of the arm so as to be located immediately above the sample loading position of the measuring device, and when the measurement sample is present on the sample loading position, the presence of the photoelectric switch is detected by the photoelectric switch. Then, the driving device of the measuring device is operated, and the measuring device is moved until the next sample loading position on which no measurement sample is loaded reaches just below the photoelectric switch.
Thereby, when measuring a plurality of magnetic materials as a measurement sample, it is possible to reliably carry the magnetic material into the measuring device one by one and move the carrier vertically downward by adsorbing the magnetic material on the carrier. In this case, a large number of magnetic bodies can be efficiently transported without dropping the magnetic bodies. According to a first aspect of the present invention, there is provided a magnetic material transporting apparatus provided with a magnetic material transporting means for transporting a magnetic material one by one by a plurality of transport tables, and an arm and the arm. A magnetic material transporting device comprising a magnetic material moving means having a suction head, and a control means for controlling the operation of the magnetic material moving means and the magnetic material moving means. At this position, the magnetic material is placed on a carrier table and transported to a predetermined position, and the suction head provided on the arm of the magnetic material moving means is moved until it comes into contact with the magnetic material. After removing the arm from the table, the arm is moved a certain distance, and then the suction by the suction head is released to release the magnetic material.
