Abstract
A label peeling device has a holding unit that can hold label paper conveyed from a label printer that ejects ink onto label paper P having labels Pb and a liner Pa to which the labels Pb are affixed; a peeling unit that is disposed downstream on the label paper P conveyance path from the holding unit, can move bidirectionally between a start peeling position separated from the holding unit and an end peeling position near the holding unit, and peels labels Pb from the liner Pa by moving from the start peeling position to the end peeling position; a motor that moves the peeling unit; an encoder that detects the position of the peeling unit; and a controller that controls the motor based on the position of the peeling unit detected by the encoder.
Claims19
A label peeling device comprising:
- a holding unit configured to hold label paper conveyed from a fluid ejection device that ejects fluid onto label paper, the label paper having a label and a liner to which the label is affixed;
- a peeling unit configured to peel the label from the liner of the label paper fed from the fluid ejection device, the peeling unit being disposed on a downstream side of the holding unit in a conveyance path of the label paper;
- a slack detector configured to detect if there is slack in the label paper;
- and
- a control unit configured to control the peeling unit to peel the label from the liner when the label paper is held by the holding unit, wherein,
- when the label paper is not held by the holding unit,
- the control unit configured to stop conveyance of the label paper if the slack detector detects there is no slack in the label paper;
- and
- the control unit configured to resume conveyance of the label paper after the slack detector detects there is slack in the label paper, after the control unit stops the conveyance of the label paper.
A fluid ejection device comprising:
- a fluid ejection unit configured to eject fluid onto label paper, the label paper including a label and a liner to which the label is affixed;
- a peeling unit configured to peel the label from the liner of the label paper fed from the fluid ejection unit;
- a holding unit configured to hold the label paper on an upstream side of the peeling unit in the conveyance path of the label paper;
- a slack detector configured to detect if there is slack in the label paper;
- and
- a control unit configured to control the peeling unit to peel the label from the liner when the label paper is held by the holding unit, wherein,
- when the label paper is not held by the holding unit,
- the control unit configured to stop conveyance of the label paper if the slack detector detects there is no slack in the label paper;
- and
- the control unit configured to resume conveyance of the label paper after the slack detector detects there is slack in the label paper, after the control unit stops the conveyance of the label paper;
- wherein, the holding unit holds the label paper when the peeling unit peels the label from the liner.
A label peeling method of a label peeling device including a holding unit configured to hold label paper having a label and a liner to which the label is affixed, and a peeling member disposed downstream of the holding unit on a label paper conveyance path, comprising:
- holding label paper conveyed from a fluid ejection device that ejects fluid onto label paper;
- peeling a label from the liner by a peeling member moving from a start peeling position to an end peeling position more proximal to the holding unit than the start peeling position;
- detecting the position of the peeling member when the peeling member moves from the start peeling position to the end peeling position;
- and
- conveying the label paper when the label paper is not held and there is slack detected in the label paper and not conveying the label paper when there is no slack detected in the label paper.
