Abstract
A holding unit holds label paper conveyed from a label printer that ejects ink onto the label paper. A peeling unit is disposed to the label paper conveyance path downstream from the holding unit, and peels labels from the liner of the label paper. The peeling unit can move bidirectionally between a start peeling position and an end peeling position. A peeling member folds back only the liner portion of the label paper. A peeling conveyance roller disposed downstream from the peeling member on the label paper conveyance path conveys the label paper. The peeling member moves from the start peeling position to the end peeling position by being pushed by the label paper conveyed by the peeling conveyance roller while the label paper is still held by the holding unit.
Claims8
A label peeling device configured to peel a label from a liner to which the label is affixed, the label peeling device comprising:
- a peeling member disposed in a conveyance path of the liner and configured to move between a first position and a second position, and to fold back the liner;
- and
- a conveyance roller disposed on a downstream side of the peeling member in the conveyance path and configured to hold the liner and to rotate;
- wherein
- the peeling member moves from the first position to the second position when being pushed by the liner, the liner pushing the peeling member when the conveyance roller holds the liner and the conveyance roller rotates while the liner is being held at a location along the liner on an upstream side of the peeling member in the conveyance path such that a portion of the liner that is upstream of the location does not travel in the conveyance path, and
- the label is peeled from the liner when the peeling member moves from the first position to the second position.
A fluid ejection device comprising:
- a fluid ejection unit configured to eject fluid onto a label affixed to a liner;
- and
- a peeling member disposed in a conveyance path of the liner and configured to move between a first position and a second position, and to fold back the liner;
- a conveyance roller disposed on a downstream side of the peeling member in a conveyance path configured to hold the liner and rotate;
- wherein
- the peeling member moves from the first position to the second position when being pushed by the liner, the liner pushing the peeling member when the conveyance roller holds the liner and the conveyance roller rotates while the liner is being held by a holding unit at a location of the liner such that a portion of the liner that is upstream of the location does not travel in the conveyance path, and
- the label is peeled from the liner when the peeling member moves from the first position to the second position.
A peeling method of a label peeling device configured to peel a label from a liner to which the label is affixed, the label peeling device having a peeling member disposed in a conveyance path of the liner and configured to move between a first position and a second position, and to fold back the liner, and a conveyance roller disposed on a downstream side of the peeling member in the conveyance path and configured to hold the liner and rotate, the peeling method comprising:
- moving the peeling member from the first position to the second position including:
- a step of holding the liner at a location along the liner on an upstream side of the peeling member in the conveyance path such that a portion of the liner that is upstream of the location does not travel in the conveyance path, and
- a step of controlling the conveyance roller, while the liner is pushing the peeling member, to hold the liner and to rotate while the liner is on the upstream side of the peeling member in the conveyance path;
- wherein,
- the label is peeled from the liner when the peeling member moves from the first position to the second position when being pushed by the liner, the liner pushing the peeling member.
