Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is a sphere measuring and sorting method that continuously measures and sorts the sphericity, roundness, and diameter of spheres made of ceramic, glass, metal, etc. It is related to the device.

(b) Prior Art Conventionally, as a method for measuring and sorting spheres, two tapered rollers 10, 10 are combined in the horizontal direction, as shown in FIGS. 4 and 5, and a A means of providing a gap 12 that gradually widens by a separator 11 interposed at the boundary, rotating the tapered rollers 10, and supplying a workpiece between them, or two knife edge plates as shown in FIGS. 6 and 7. 13, 13 are laterally combined to form a knife edge plate 13,
A gap 15 which gradually widens is provided by a separator 14 interposed at the boundary between the knife edge plates 13, 13, and a workpiece is fed to a location where the knife edge plates 13, 13 are inclined. When these gaps are set in a tapered shape, the sorting accuracy is low because rotation that covers the entire sphere is not given at the same gap position, and it is difficult to set the position of the separator at the boundary because the gaps are not parallel. However, there were drawbacks such as affecting accuracy.

(C) Problems to be Solved by the Invention The problems to be solved by the present invention are to solve the above-mentioned drawbacks of the conventional means at once, and to provide rotation over the entire sphere at the same gap position. The object of the present invention is to provide a sphere measuring and sorting device that can perform stable and highly accurate sphere measuring and sorting.

(d) Means for solving the problems In order to solve the above problems, the present invention has the following steps:
A plurality of sliding knife edge plates each having a knife edge surface that forms a gap that gradually widens in a stepwise manner in the lateral direction between a suitably inclined rotatable parallel roller and a surface along the axial direction of the parallel roller. The present invention aims to provide a sphere measuring and sorting device consisting of the following.

(e) Effect Next, the effect will be explained.

Appropriate rotation is given to the parallel rollers to rotate the workpiece, and a plurality of sliding knife edge plates form a specified gap that gradually widens in the lateral direction between the parallel rollers and the surface along the axial direction. The workpiece is then positioned so that the workpiece is tilted appropriately, and the workpiece is fed from the entrance side, which is the direction where the gap is narrower.

At this time, for example, spheres with a smaller diameter than the standard are sorted out in the gap on the entrance side, regular spheres in the next gap, and spheres with a larger diameter than the standard are sorted out and dropped in the gap further ahead. In the process of falling over the gap, the same gap part has a certain length section in the roller axis direction, so the sphere is continuously given rotation in the direction perpendicular to it while rolling in that section. ,
The sphere is rotated not only in one direction but also throughout.

(F) Embodiment Hereinafter, the structure of an embodiment of the present invention will be described with reference to FIGS. 1 to 3 of the drawings.

Knife edge plates 2, 3, and 4 are installed in the lateral direction of a rotatable parallel roller 1.

The knife edge plates 2, 3, and 4 are each movable in a direction perpendicular to the surface along the axial direction of the roller 1, and are sequentially arranged between the knife edge surface and the surface along the axial direction of the roller 1. Set to form a step-like gap, rank 5 has a narrow gap according to the specified value of the spherical diameter of the workpiece to be measured from the inlet side of the workpiece, the next gap is specified as rank 6, and the gap beyond that is specified as specified. Adjust with block gauge etc. so that it becomes a large rank 7. Separators 9 are provided at the boundaries of each rank 5, 6, and 7, respectively. The entire roller, knife edge plate, etc. are tilted at an appropriate angle, and a workpiece is introduced from the entrance side 8.

As the workpiece rolls, it is continuously given further rotation in the right angle direction by the rollers, rotates the entire workpiece, and sequentially falls into the shortest gap that can accommodate the spherical shape of the sphere, and is sorted.

(g) Effects of the Invention As is clear from the above description, the present invention provides a system in which a rotatable parallel roller that is tilted appropriately and a surface along the axial direction of the parallel roller are provided with a horizontally sequential step-like structure. Since it is constructed by combining multiple sliding knife edge plates with knife edge surfaces that form widening gaps, the rotation of the spheres, which is important in sorting spheres, is applied not only in one direction but over the entire body, resulting in sorting accuracy. In addition to this, the gap between the parallel rollers and the edge surface of the knife edge plate can be freely adjusted and set.
