Embroidery apparatus
An embroidery apparatus includes a main unit to be detachably mounted on a bed section of a sewing machine, a first translation mechanism that moves an embroidery frame holder with an embroidery frame mounted thereon in a first direction, a second translation mechanism that moves the first translation mechanism along an upper surface of the main unit in a second direction that orthogonally intersects the first direction, and an elevator mechanism that is supported by the second translation mechanism at opposite sides of the main unit and that raises and lowers the first translation mechanism. The embroidery apparatus is applicable to a sewing machine switchable between embroidery stitching and standard stitching. During standard stitching, the upper surface of the first translation mechanism is flush with the upper surface of the main unit, which enables both upper surfaces to be used as an auxiliary table.
1. An embroidery apparatus, comprising:
a main unit to be detachably mounted on a bed section of a sewing machine;
a first translation mechanism that moves an embroidery frame holder with an embroidery frame mounted thereon in a first direction, the embroidery frame extending horizontally;
a second translation mechanism that moves the first translation mechanism along an upper surface of the main unit in a second direction that orthogonally intersects the first direction; and
an elevator mechanism that is supported by the second translation mechanism at opposite sides of the main unit and that raises and lowers the first translation mechanism while the embroidery frame is maintained to extend horizontally.
2. An embroidery apparatus, comprising:
a main unit to be detachably mounted on a bed section of a sewing machine;
a first translation mechanism that moves an embroidery frame holder with an embroidery frame mounted thereon in a first direction;
a second translation mechanism that moves the first translation mechanism along an upper surface of the main unit in a second direction that orthogonally intersects the first direction; and
an elevator mechanism that is supported by the second translation mechanism at opposite sides of the main unit and that raises and lowers the first translation mechanism,
wherein the elevator mechanism includes a pair of hinge arms that are swingably supported by the second translation mechanism, and
wherein the hinge arms are swingable so as to move closer to each other and away from each other, and the swing movement of the hinge arms raises and lowers the first translation mechanism horizontally.
3. The embroidery apparatus according to claim 2 , wherein
the first translation mechanism has
an elevator driving shaft that rotates with a rotation axis extending in the first direction, and
a pair of first support seats that move in the first direction due to rotation of the elevator driving shaft, and
each of the hinge arms has
a first end portion pivotally supported by the second translation mechanism using a fulcrum shaft, and
a second end portion pivotally connected to a corresponding one of the first support seats.
4. The embroidery apparatus according to claim 1 , wherein
the elevator mechanism has an elevator shaft that is rotatably supported by the second translation mechanism and configured to rotate forward and backward and thereby raise and lower the first translation mechanism.
5. The embroidery apparatus according to claim 4 , wherein
the elevator mechanism has
a drive unit that is disposed at the second translation mechanism and that rotates the elevator shaft, and
a second support seat that supports the first translation mechanism using the elevator shaft so as to be able to raise and lower the first translation mechanism.
6. An embroidery apparatus, comprising:
a main unit to be detachably mounted on a bed section of a sewing machine;
a first translation mechanism that moves an embroidery frame holder with an embroidery frame mounted thereon in a first direction;
a second translation mechanism that moves the first translation mechanism along an upper surface of the main unit in a second direction that orthogonally intersects the first direction; and
an elevator mechanism that is supported by the second translation mechanism at opposite sides of the main unit and that raises and lowers the first translation mechanism,
wherein upon receiving a storage instruction, the first translation mechanism moves the embroidery frame holder to an end of the first translation mechanism and issues a first storage-ready notification, and the second translation mechanism moves the first translation mechanism in the second direction to a position outside the main unit and issues a second storage-ready notification, and
wherein upon receiving the first storage-ready notification and the second storage-ready notification, the elevator mechanism lowers the first translation mechanism until an upper surface of the first translation mechanism is flush with the upper surface of the main unit.
7. The embroidery apparatus according to claim 2 , wherein,
upon receiving a storage instruction, the first translation mechanism moves the embroidery frame holder to an end of the first translation mechanism and issues a first storage-ready notification, and the second translation mechanism moves the first translation mechanism in the second direction to a position outside the main unit and issues a second storage-ready notification, and
upon receiving the first storage-ready notification and the second storage-ready notification, the elevator mechanism lowers the first translation mechanism until an upper surface of the first translation mechanism is flush with the upper surface of the main unit.
8. The embroidery apparatus according to claim 3 , wherein,
upon receiving a storage instruction, the first translation mechanism moves the embroidery frame holder to an end of the first translation mechanism and issues a first storage-ready notification, and the second translation mechanism moves the first translation mechanism in the second direction to a position outside the main unit and issues a second storage-ready notification, and
upon receiving the first storage-ready notification and the second storage-ready notification, the elevator mechanism lowers the first translation mechanism until an upper surface of the first translation mechanism is flush with the upper surface of the main unit.
9. The embroidery apparatus according to claim 4 , wherein,
upon receiving a storage instruction, the first translation mechanism moves the embroidery frame holder to an end of the first translation mechanism and issues a first storage-ready notification, and the second translation mechanism moves the first translation mechanism in the second direction to a position outside the main unit and issues a second storage-ready notification, and
upon receiving the first storage-ready notification and the second storage-ready notification, the elevator mechanism lowers the first translation mechanism until an upper surface of the first translation mechanism is flush with the upper surface of the main unit.
10. The embroidery apparatus according to claim 5 , wherein,
upon receiving a storage instruction, the first translation mechanism moves the embroidery frame holder to an end of the first translation mechanism and issues a first storage-ready notification, and the second translation mechanism moves the first translation mechanism in the second direction to a position outside the main unit and issues a second storage-ready notification, and
upon receiving the first storage-ready notification and the second storage-ready notification, the elevator mechanism lowers the first translation mechanism until an upper surface of the first translation mechanism is flush with the upper surface of the main unit.
