Then, at the work replacement position, after the tested seismic isolation rubber is removed from the work carriage, new seismic isolation rubber to be tested next is supplied.

Since the single work cart is reciprocated to carry the seismic isolation rubber in and out, the seismic isolation rubber that has been tested at the work exchange position and a new seismic isolation rubber that is to be tested next. In order to replace the rubber, it is necessary to wait for the tested seismic isolation rubber to be carried out together with the work cart after the test of one seismic isolation rubber is completed. Therefore, it takes a lot of time to carry in and take out each seismic isolation rubber to be shipped, and there is a need for improvement in order to process as quickly as possible.

In the work loading / unloading device for the seismic isolation rubber tester, the work carriage is moved by one cylinder between the work exchange position and the work processing position together with the seismic isolation rubber. Requires a travel stroke of about 5 m. Therefore, much space is required for installing a long cylinder. In addition, the piston rod is removed from the work cart carried into the work processing position and moved so as not to hinder the test of the seismic isolation rubber, but since the piston rod is long as described above, it must withstand its own weight. The cylinder must be made robust.

In addition, the workpiece is again transported to the first position by the return movement of the relay bogie 34 due to the driving of the work bogie loading / unloading device 22.

Between the loading and unloading, the tested work is removed from the work cart 42 located at the second position on the E side in FIG. 2A. Then, new seismic isolation rubber 2 to be tested next is supplied.

Next, after the work cart 43 on which the tested seismic isolation rubber 2 has been loaded by the above-described unloading is pulled out onto the common cart 23 and arranged at the first position, the common cart moving device 24 is driven. As a result, the common carriage 23 is moved to the F side by a fixed stroke S as shown by a solid line in FIG. Thereby, the work cart 43 already carried out to the first position is arranged at the second position, and the work cart 42 further supplied with new seismic isolation rubber 2 is arranged at the first position. With the movement of the work cart 42 to the first position, the engaging portion 45 enters directly below the engaging portion 36 of the relay cart 34 so that the engaging portions 36 and 45 can engage with each other.
