<Sphere tank>
The spherical tank 1 is a box 3 having a substantially rectangular outer shape, and the bottom surface 4 of the box 3 is inclined low so that the sphere flows down from one end to the other end. At the downstream end thereof, one central partition wall 8 and two small partition walls 7 are erected at intervals of one sphere, and one sphere is interposed between these partition walls 8 and 7. A ball passage with a width of minutes is formed. Further, the upper ends of the partition walls 8 and 7 are raised toward the downstream side and are inclined reversely with respect to the box bottom surface 4 to sort the spheres. The central partition 8 is for dividing the flow of the sphere in the sphere tank 1 into two substantially left and right, and its upper end is inclined to the left and right. Further, side slopes 11 are provided on both sides of the bottom face 4 of the box body 3 so as to be reversely inclined with respect to the box bottom face 4 and slightly lower toward the inside, thereby facilitating guidance of the sphere. is there. Accordingly, the central partition wall 8, the small partition walls 7, and the side slopes 11 form four rows of the spherical guide rods 5 through which the balls pass in a row (FIG. 3).

  A plurality of step portions 6 are formed on the bottom surface of the ball guide rod 5 so that the front and rear spheres are separated by flow resistance due to the curvature of the partition walls 8 and 7 and acceleration by the step portions 6. .

  Further, a tank auxiliary member 13 having a plate-like bottom surface 12 that is inclined reversely with respect to the box bottom surface 4 is detachably contacted above the ball guide rod 5 so as to cover the upper portion of the ball guide rod 5.
