Description

[Detailed description of the invention] The present invention relates to a spherical object sorting device that separates spherical objects with irregular shapes and twin-shaped spherical objects with two spherical objects attached from round spherical objects, and has a round groove screw. By devising the structure and arrangement of the feed roller and round guide roller,
It is an object of the present invention to provide a spherical object sorting device that can very easily and accurately distinguish irregularly shaped and twin-shaped spherical objects from ball-like objects.

The present invention will be explained below with reference to the embodiments shown in the drawings. Figure 1 is a plan view, Figure 2 is a side view showing only the roller end, Figure 3 is a front view of the feed roller, and 1 is a spherical shape to be sorted. This feed roller is formed with round groove screws 3 having a pitch slightly larger than the diameter of one spherical object (ball-shaped spherical object 2, irregularly shaped or twin-shaped spherical object 2a).

4 is slightly spaced apart from and parallel to the feed roller 1;
The feed roller 1 is positioned obliquely above the guide roller 4 as shown in FIG. 2, and a line x - is inclined at an angle θ1 from the horizontal, and the axes of both rollers are arranged at an angle θ2 from the horizontal.

Arrow A in FIG. 3 indicates the direction in which the spherical objects to be sorted are supplied, and the spherical objects are fed from above the feed roller 1 and the guide roller 4, as indicated by the arrow A.

Further, the rotational direction of the feed roller 1 is such that the feeding direction of the screw is a direction in which the spherical object is transferred obliquely upward.

Now, the spherical object to be sorted is at an angle of θ2 from the horizontal.
Feed roller 1 and guide roller 4 arranged at an angle
When an appropriate amount of the spherical material 2 is fed into the center from above as shown by arrow A, the correct spherical material 2 fits into the round groove screw 3 of the feed roller 1 and is transported upward by the rotating screw. The end portions are collected as non-defective products in a case (not shown) or the like.

On the other hand, the twin spherical vIJ2a is formed so that the pitch of the round groove screws of the feed roller 1 is slightly larger than the diameter of the spherical object, so that the two twin spherical objects are adjacent to each other at the same time as the round groove screw 3, 3, and if one fits, the other rests on the thread 3a, and gradually rolls downward as shown in Fig. 3, swinging like a seesaw with the top of the thread 3a as a fulcrum. However, it reaches the lower end of the roller and is collected as a defective product.

In addition, a spherical object with an abnormal shape such as a knob is difficult to fit into the round groove screw 3 portion of the feed roller 1, falls over the guide roller, and is similarly collected as a defective product.

As explained above, according to the present invention, despite the extremely simple structure, abnormal shapes and twin-shaped spherical objects can be precisely detected.
The spherical objects can be sorted and collected separately.

Furthermore, if the angles of the center lines of both rollers are reversed as shown in Fig. 2, that is, the guide roller 4 is positioned diagonally above the feed roller 1, defective products will be transported upward along with non-defective products and cannot be sorted. It turns out.

In addition to tablets, the present invention can also screen other spherical objects.

Claims (1)

[Scope of utility model registration request] In a spherical object sorting device comprising a feed roller having a round groove screw that rotates in the same direction, and a round bar-shaped guide roller running parallel to the feed roller at a slight distance from the feed roller, the round groove screw is used to separate the spherical objects to be sorted. The pitch is slightly larger than the diameter of the object, and the feed roller is positioned diagonally above the guide roller, and the line connecting the axial centers of both rollers is inclined by an angle θ1 from the horizontal, and the axial center of both rollers is Each of the feed rollers is tilted at an angle of θ2 from the horizontal, and the rotating direction of the feed rollers is such that the feeding direction of the screw is a direction in which the spherical objects are transferred obliquely upward, and the rollers are arranged so that an appropriate amount of the spherical objects are to be sorted from above the central offshore area. A spherical object sorting device characterized by supplying spherical objects one by one.
