Abstract

A conveyance device and a planar conveyance apparatus capable of carrying out an article in any direction. The conveyance device includes an energizing mechanism unit configured to energize and move an article and a rotation mechanism unit configured to rotate the energizing mechanism unit itself, and is capable of changing a moving direction of the article by rotating the energizing mechanism unit with the rotation mechanism unit. The energizing mechanism unit includes an energizing mechanism side motor, and the energizing mechanism side motor includes a coil on a center side and an outer body surrounding the coil, and is an outer rotor type motor in which the outer body rotates. The energizing mechanism side motor is disposed such that a central shaft of the outer body is in a substantially horizontal posture, and the outer body energizes the article by coming into contact with the article directly or through a freely-rotating rotor interposed therebetween.

First claim

The invention claimed is:

1. A conveyance device that comprises:
an energizing mechanism unit configured to energize and move an article; and
a rotation mechanism unit configured to rotate the energizing mechanism unit itself to change a moving direction of the article,
wherein the energizing mechanism unit comprises an energizing mechanism side motor,
the energizing mechanism side motor including: a coil on a center side; and an outer body surrounding the coil,
the energizing mechanism side motor being an outer rotor type motor in which the outer body rotates,
wherein the energizing mechanism side motor is disposed such that a central shaft of the outer body is in a substantially horizontal posture, and
wherein the outer body is configured to come into contact with the article directly or through a freely-rotating rotor interposed therebetween to energize the article.

2. The conveyance device according to claim 1 ,
wherein the rotation mechanism unit comprises a rotation mechanism side motor,
the rotation mechanism side motor including a coil on a center side and an outer body surrounding the coil,
the rotation mechanism side motor being an outer rotor type motor in which the outer body rotates,
wherein the rotation mechanism side motor is disposed such that a central shaft of the outer body is in a substantially vertical posture, and
wherein the outer body is engaged with the energizing mechanism unit directly or indirectly.

3. The conveyance device according to claim 1 , further comprising a freely-rotatable roller, wherein a part of the freely-rotatable roller is configured to come into contact with the energizing mechanism side motor to energize the article.

4. The conveyance device according to claim 3 , wherein one or a plurality of the rollers have a degree of freedom in a vertical direction.

5. The conveyance device according to claim 1 ,
wherein a friction imparting member is provided on an outer peripheral portion of the outer body of the energizing mechanism side motor, and
wherein the energizing mechanism side motor is configured to come into contact with the article to energize the article.

6. A conveyance device that comprises:
an energizing mechanism unit configured to energize and move an article; and
a rotation mechanism unit configured to rotate the energizing mechanism unit itself to change a moving direction of the article,
wherein the rotation mechanism unit comprises a rotation mechanism side motor,
the rotation mechanism side motor including a coil on a center side and an outer body surrounding the coil,
the rotation mechanism side motor being an outer rotor type motor in which the outer body rotates,
wherein the rotation mechanism side motor is disposed such that a central shaft of the outer body is in a substantially vertical posture, and
wherein the outer body is engaged with the energizing mechanism unit directly or indirectly.

7. A planar conveyance apparatus comprising a plurality of the conveyance devices according to claim 1 , the plurality of the conveyance devices being arranged in a planar shape.

8. A planar conveyance apparatus comprising a plurality of the conveyance devices according to claim 6 , the plurality of the conveyance devices being arranged in a planar shape.

9. The conveyance device according to claim 2 , further comprising a freely-rotatable roller, wherein a part of the freely-rotatable roller is configured to come into contact with the energizing mechanism side motor to energize the article.

10. The conveyance device according to claim 9 , wherein one or a plurality of the rollers have a degree of freedom in a vertical direction.

11. The conveyance device according to claim 2 ,
wherein a friction imparting member is provided on an outer peripheral portion of the outer body of the energizing mechanism side motor, and
wherein the energizing mechanism side motor is configured to come into contact with the article to energize the article.
