Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for inspecting run-out and outer diameter of rollers such as a top roller.

[0002]

2. Description of the Related Art On a bottom roller of a spinning machine such as a spinning frame or a roving frame, a top roller having a rubber layer formed on a surface thereof is pressed and arranged as a drafting means for roving or sliver. Since the surface of the rubber layer becomes rough as the spinning time elapses, the top roller is removed from the spinning machine after a predetermined use time, and the surface of the rubber layer is polished smoothly. Good products are reused, and defective products are re-ground or discarded.

Conventionally, the inspection of the run-out and outer diameter of the top roller after polishing has been carried out by placing the top roller on an inspection roller, rotating the top roller, and applying a dial gauge to the top roller.

[0004]

However, it is difficult to perform a precise inspection with the above-mentioned conventional methods for detecting runout and outer diameter. In particular, recently, a high precision of 1/100 mm has been required for the runout, and the conventional method cannot cope with the runout. Moreover, if the dial gauge detects that there is a run-out, the run-out includes an error due to the run-out of the inspection roller,
There was a fatal drawback that these could not be identified.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for inspecting the runout and outer diameter of rollers for preventing the intervention of an error from the rotation imparting means and enabling a highly accurate runout and outer diameter inspection. .

[0006]

In order to achieve the above object,
The present invention provides a supporting means having a V-block portion for centering and supporting an arbor portion of a roller, and a free running portion between the two pulleys of a belt endlessly stretched on a driving pulley and a driven pulley. A rotation applying means for rotating the roller by contacting the surface of the roller, and a projector which is installed opposite to the surface of the roller and detects the deflection and outer diameter of the roller by a change in the amount of received parallel light or the amount of light shielding. And an optical measuring means comprising a light receiver and a deflection and outer diameter inspection device for rollers.

[0007] Since the present invention has the above-described configuration, it is possible to prevent the intervention of an error from the rotation imparting means and to perform a highly accurate run-out and outer diameter inspection when the run-out and outer diameter of the roller are inspected. That is, according to the present invention, the free running portion between the two pulleys of the belt stretched endlessly on the driving pulley and the driven pulley is brought into contact with the surface of the roller to rotate the roller. According to the first aspect, the belt can be flexibly deformed and the rotation can be smoothly transmitted while allowing the deflection. Then, when there is a shake, the amount of light received by the light receiver of the parallel rays emitted from the light emitter fluctuates in amplitude by an amount corresponding to the shake, and the amount of shake is measured by the amplitude change,
It is determined whether the product is within an allowable range or not, and non-defective / defective products are selected. It should be noted that the belt is driven at a relatively slow speed, and a run-out error caused by the belt does not intervene. Inspection of the outer diameter of the roller is performed by measuring the change in the amount of parallel rays emitted from the projector to the light receiver, as in the above, and determining whether or not this is within the allowable range. Is performed.

The present invention is also directed to a means for carrying in a roller before inspection to a supporting means, a means for carrying out a roller after inspection from the supporting means, and a means for carrying out the roller carried out by the carrying out means to the optical measuring means. Means for sorting out non-defective / defective products based on the inspection result of (1), the roller run-out and outer diameter inspection can be performed fully automatically.
