Compact gravity-driven distribution mechanism for spherical objects

Abstract

A compact gravity-driven distribution mechanism for spherical objects comprises a spherical objects container, a deflector inside the container, and a spherical objects regulator with a rotary plate attached at the bottom. Spherical objects are pre-loaded or dynamically flow into the spherical objects container and the deflector in the container guides spherical objects into the spherical objects regulator underneath the container. The spherical objects regulator regulates the spherical objects into three chambers where the spherical objects are ready for discharge. Spherical objects flow out of the spherical objects regulator in three streams. The rotary plate can be rotated to shut or open the channel of spherical objects flow. Spherical object flow is driven solely by gravity, which makes the mechanism energy efficient. The compound structure of this mechanism can be small and compact, making it easy to be deployed.

DETAILED DESCRIPTION OF THE INVENTION

(12) Referring to FIG. 1 and FIG. 2, one embodiment of a compact gravity-driven distribution mechanism for spherical objects is generally shown as including at least a spherical objects container 1, a spherical objects regulator 2, a rotary plate 3, and a deflector 4. The spherical objects container 1 is connected to the spherical objects regulator 2 by three brackets 5. The rotary plate 3 is attached to the bottom of the spherical objects regulator 2 by three circular U section rails 6, as shown in FIG. 2 and FIG. 4.

(13) The spherical objects container 1 stores and also receives spherical objects. As shown in FIG. 5 and FIG. 6, the spherical objects container 1 comprises of an outer cylinder body 12 and a shallow inverted cone-shaped ring 13. At the center of the shallow inverted cone-shaped ring 13 is a dropping hole 9, where spherical objects flow into the spherical objects regulator 2. The shallow inverted cone-shaped ring 13 forms a slope stretching from the circular wall of the outer cylinder body 12 towards the dropping hole 9, which helps spherical objects at the bottom of the spherical objects container 1 flow towards the dropping hole 9.

(14) The deflector 4 is a round cap with its top being part of a sphere and its bottom being flat and parallel to the ground, and its circular edge is blended to avoid sharp corner. The deflector 4 is installed inside the spherical objects container 1 to guide the flow of spherical objects and avoid the congestion of spherical objects directly above the dropping hole 9 of the spherical objects container 1, as shown in FIG. 1 and FIG. 3. The deflector 4 is connected to the outer cylinder body 12 of the spherical objects container 1 by three rods 10. The three rods 10 are attached to three brackets 11, as shown in FIG. 1 and FIG. 3. The deflector 4 eliminates the pressure from spherical objects above the dropping hole 9 to the spherical objects entering the dropping hole 9, which ensures spherical objects flow into the dropping hole 9 from surrounding areas of the dropping hole 9 with no chance to congest at the dropping hole 9.

(15) The spherical objects regulator 2 in FIG. 7 and FIG. 8 is the place where spherical objects get regulated to specific locations for distribution. As shown in FIG. 8 and FIG. 10, an intake hole 14 is at the center of the top of the spherical objects regulator 2, through which spherical objects flow into the spherical objects regulator 2 from the spherical objects container 3. The intake hole 14 has the same diameter as the dropping hole 9, and it is placed concentrically with the dropping hole 9 and right below the dropping hole 9. A guiding pole 15 sits at the bottom of the spherical objects regulator 2. It is concentric with the intake hole 14 and sticks out of the intake hole 14, helping to guide the spherical objects being pushed into the intake hole 14 by gravity. At the bottom of the spherical objects regulator 2 sits a cone disc 16 concentric with the guiding pole 15. The guiding pole 15 passes through the cone disc 16. Once spherical objects flow into the spherical objects regulator 2, the cone disc 16 helps them move from center of the spherical objects regulator 2 towards its outskirts. On the outskirts of the spherical objects regulator 2 are three chambers 17, they are separated by three guiding islands 18. At the bottom of the three chambers 17 are three discharge holes 19, where two spherical objects can easily pass through shoulder to shoulder at the same time. The three guiding islands 18 are rounded with smooth faces, and they help guide spherical objects into the three chambers 17, where said spherical objects are ready to be released. To further assist spherical objects in moving towards the three chambers 17, three bumper shape destabilizers 20 are installed on top of the cone disc 16, each of them passes through the symmetric plane of each of the three guiding islands 18.

(16) The rotary plate 3 is designed to control the release of spherical objects from the three chambers 17. It has three release holes 8, each of them has the same shape as each of the discharge holes 19. The three release holes 8 can perfectly overlap the discharge holes 19. A ring gear 7 is attached to the bottom of the rotary plate 3 and is concentric to the rotary plate 3. An external gear system can be paired with the ring gear 7, being driven either manually or by a low capacity motor. When the three release holes 8 are aligned to the discharge holes 19 of the spherical objects regulator 2 as shown in FIG. 2, spherical objects will be released from the three chambers 17, and spherical objects keep moving into the three chambers 17 and then get released. When the rotary plate 3 is rotated to a position where the three discharge holes 19 of the spherical objects regulator 2 are completely covered by the rotary plate 3, the flow of spherical objects is halted.
