What this pole curved detection mechanism adopted is that contact detects, and promptly the method for directly touching presser feet by tested pole two ends detects the degree of crook of pole.Facts have proved that when tested pole during for the bamboo wood pole carefully grow, this contact detection false drop rate is higher.Trace it to its cause and be, elongated bamboo wood pole rigidity is less, radially be subjected to less power with regard to flexible distortion, tested pole self is as existing bending, its two ends are easy to change original degree of crook (curvature diminishes) under the presser feet active force when touching presser feet, thereby can not be with the effective jack-up of presser feet, cause detecting malfunctioning, flase drop occurs.
In addition, this presser feet contact detects and also has another shortcoming, is exactly complex structure, debugs loaded down with trivial details.
Three, utility model content
The purpose of this utility model is improved at the shortcoming that above-mentioned existing pole curved detection mechanism exists, and a kind of simple in structure, pole curved detection mechanism that false drop rate is low is provided and is provided with the automatic detection and selection machine of pole of this mechanism.
Above-mentioned purpose realizes by adopting non-contact type detection replacement contact to detect.
The pole curved detection mechanism that the utility model provides, the combined driving-belt that band and following band constitute on the middle part of tested pole has by the rightabout rotation, wherein be with top to place the groove of material platform down, its outer surface slightly exceeds the benchmark table top of material platform, is slightly less than the diameter of tested pole with the spacing of last band bottom; In the outside of combined driving-belt the one group of limiting plate that is fixed on the support is arranged, this limiting plate bottom surface and tested pole have minim gap; The back width highly is higher than material plane, road less than the spacing of adjacent two poles on the material road in face of the standard station of described material platform; The both ends of corresponding tested pole have photoelectric sensor respectively.
For alleviating the friction of being with down with material platform groove floor, corresponding described groove can be installed and the contacted bearing in following band bottom surface in described material platform.
The operation principle of the utility model pole curved detection mechanism is: tested pole is driven when proceeding to pole curved detection mechanism by the defeated material chain of detection and selection machine, on climb the benchmark table top of material platform along the following band of the combined driving-belt of curved detection mechanism (because of the benchmark table top of material platform is higher than material plane, road, tested pole two ends were left the material road and were vacant state this moment), under band on the combined driving-belt and the rubbing of following band, when continuing to move ahead, self radially rotate with defeated material chain, if pole exists crooked, its both ends must the perk with the rotation of pole.When the pole degree of crook exceeded standard-required (preestablishing by the optical fiber height of regulating photoelectric sensor), the pole end that the light beam of photoelectric sensor is upwarped stopped that photoelectric sensor then provides the defective signal of tested pole flexibility.
The utility model pole curved detection mechanism, the front and back width that why requires material platform datum table top is less than the spacing of adjacent two poles on the material road and highly be higher than and expect the plane, road, the former is in order to ensure a tested pole can only be arranged on the benchmark table top, and other pole does not all enter the detection range of light beam; The latter is in order the optical fiber of photoelectric sensor to be installed in the top of tested pole.
The advantage of the utility model pole curved detection mechanism, the one, to detect replacement presser feet contact with the light beam non-contact type and detect, tested pole two ends are not subjected to the external force effect in testing process, can not be out of shape, and guarantee to detect accurately, and false drop rate is low; The 2nd, removed complicated presser foot component, simple in structure, debugging easily.
