Problems solved by technology
However, since the culture material and bacteria are flying in the culture room, for example, the culture material and bacteria flying between the light-emitting part and the light-receiving part of the optical sensor hinder normal measurement.
In addition, the height of the gantry, which is the measurement object of the distance sensor, changes greatly with the lifting and lowering of the repair machine or the discharge nut, so measurement errors occur depending on each height.
Therefore, the method disclosed in Patent Document 1, which uses distance sensors to detect the difference in height between the inner and outer sides in the radial direction as the inclination of the repair machine or the ejection nut, is not practical.

Embodiment Construction
[0037] Hereinafter, embodiments for implementing the present invention will be described with reference to the drawings. The present invention can be applied to repair machines or discharge nuts that are raised and lowered by screwing a back nut onto a rotating threaded shaft regardless of the type of solid culture device. In addition, the structure of the back nut wear detection device centering on the distance sensor is not greatly different between the case of applying the present invention to a repair machine and the case of applying it to a discharge screw. After this, below in the rotary disc solid culture device, just be equipped with the repair machine ( Figure 1 ~ Figure 3 and Figure 5 ) for this example, and as another example, a repair machine with a dummy nut arranged under the support nut ( Figure 4 ), descriptions and illustrations of the discharge screw in the rotary disk solid culture device, and other repair machines and discharge screws other than the ro...

The invention discloses a repairing machine for detecting solid culturing apparatus or a method for detecting wearing of supporting nut of discharged nut. The method for detecting wearing of the supporting nut of the repairing machine (1) of solid culturing apparatus in the solid culturing apparatus of the repairing machine (1) which enables a rotary thread shaft (12) which screws a supporting nut (11) to rotate and lift detects position changes of the supporting nut (11) relative to a fake nut (13) which links and lifts along with the repairing machine (1) as for the wearing of the supporting nut (11).
Description
technical field [0001] The present invention relates to a back nut wear detection method for reporting to the outside the state of wear of a repair machine included in a solid culture device or a back nut of a discharge screw, and the back nut wear detection device. Background technique [0002] The solid culture device includes, for example, a lifter or a discharge nut on a rotating culture bed. The repair machine or the discharge nut screw the support nuts provided on the main bodies of the repair machine or the discharge nut to the rotating screw shafts provided on the inner and outer sides in the radial direction of the rotating cultivation bed, and the rotating screw shafts are rotated to lift, Basically, it stays above, but when the repair machine is repairing, the discharge screw is lowered when the culture material is filled or discharged. Therefore, the repair machine or the discharge screw is repeatedly raised and lowered, and the threaded shaft and the support nu...
