Abstract
This conveying device is provided with: first rod-shaped members 2A, 2B that include magnetic members and have a spiraling pattern; first couplers 42A, 42B fixed to the ends of the first rod-shaped members 2A, 2B; second rod-shaped members 12A, 12B that include magnetic members and have a spiraling pattern; and second couplers 52A, 52B that link with the first couplers 42A, 42B and that are fixed to the ends of the second rod-shaped members 12A, 12B, the second couplers 52A, 52B linking with the first couplers 42A, 42B so that when the couplers are linked, the relative angles between the spiraling pattern of the first rod-shaped members 2A, 2B and the spiraling pattern of the second rod-shaped members 12A, 12B are fixed.
Claims10
A transfer apparatus comprising:
- a first rod-shaped member that comprises a magnetic material, the first rod-shaped member being provided with a first spiral pattern;
- a first coupler that is fixed to an end portion of the first rod-shaped member;
- a second rod-shaped member that comprises a magnetic material, the second rod-shaped member being provided with a second spiral pattern;
- a second coupler that is fixed to an end portion of the second rod-shaped member, the second coupler being coupled to the first coupler so as to make a relative angle between the first spiral pattern of the first rod-shaped member and the second spiral pattern of the second rod-shaped member constant when coupled to each other;
- an opposite member that is opposed to parts of side surfaces of the first and second rod-shaped members, the opposite member comprising a magnetic material;
- and
- a driving device that rotates the first and second rod-shaped members about central axes of the first and second rod-shaped members to move the opposite member along the first and second rod-shaped members.
