Abstract

A label winding device is for receiving a medium including a label liner and a label member that is removably attached to the label liner and has at least one label portion and a waste portion, separating the waste portion from the label liner at a waste separation portion, and winding the at least one label portion with the label liner. The label winding device includes: a waste winder for winding the separated waste portion; a label winder for winding the at least one label portion with the label liner without the separated waste portion; a waste guide for guiding the separated waste portion to the waste winder; a support for rotatably supporting the waste guide; a sensor for detecting a rotational speed of the waste guide; and a waste break detector for detecting break of the waste portion on a basis of the detection by the sensor.

First claim

What is claimed is:

1. A label winding device for receiving a medium including a label liner and a label member that is removably attached to the label liner and has at least one label portion and a waste portion, separating the waste portion from the label liner at a waste separation portion, and winding the at least one label portion with the label liner, the label winding device comprising:
a waste winder for winding the separated waste portion;
a label winder for winding the at least one label portion with the label liner without the separated waste portion;
a rotatable waste guide for guiding the separated waste portion to the waste winder;
a sensor for outputting a detection signal indicating whether the waste guide is rotating; and
a waste break detector for detecting break of the waste portion on a basis of the detection by the sensor.

2. The label winding device of claim 1 , wherein the waste guide forms a waste separation angle at the waste separation portion.

3. The label winding device of claim 1 , further comprising a circular slit plate connected to the waste guide so as to rotate with the waste guide, the slit plate including a circular portion having an opening portion and an non-opening portion,
wherein the sensor is configured to detect one of the opening portion and the non-opening portion depending on a rotational position of the slit plate and output, as a detection value to the waste break detector, a first value when the sensor detects the opening portion and a second value different from the first value when the sensor detects the non-opening portion.

4. The label winding device of claim 3 , wherein the waste break detector is configured to detect that the waste portion has broken if the detection value output from the sensor is constant for a predetermined period of time.

5. The label winding device of claim 1 , further comprising an alarm for alerting an operator if the waste break detector detects break of the waste portion.

6. The label winding device of claim 1 , further comprising a waste guide installation portion in which the waste guide is slidably disposed.

7. The label winding device of claim 6 , wherein the waste guide installation portion has a movement limiting frame for limiting a range of movement of the waste guide.

8. The label winding device of claim 7 , wherein the movement limiting frame is horizontally disposed.

9. The label winding device of claim 8 , wherein:
the waste winder is configured to wind the waste portion to form a waste roll;
the label winder is configured to wind the at least one label portion with the label liner to form a label roll; and
the movement limiting frame extends across a common tangent line touching both the waste roll and the label roll when a diameter of the label roll is maximum and a diameter of the waste roll is minimum.

10. The label winding device of claim 7 , wherein the movement limiting frame is disposed so that an angle at which the waste portion is guided to the waste winder by the waste guide is substantially independent of a sliding position of the waste guide.

11. The label winding device of claim 7 , further comprising an urging member for urging the waste guide in the movement limiting frame in a predetermined direction.

12. The label winding device of claim 11 , wherein the urging member is configured to slide the waste guide in response to a change in tension applied to the medium by the waste winder and a change in tension applied to the medium by the label winder.

13. The label winding device of claim 7 , further comprising:
a waste guide position sensor for detecting a sliding position of the waste guide in the movement limiting frame; and
a controller for controlling a winding torque of the waste winder in accordance with the sliding position detected by the waste guide position sensor.

14. A label winding device for receiving a medium including a label liner and a label member that is removably attached to the label liner and has at least one label portion and a waste portion, separating the waste portion from the label liner at a waste separation portion, and winding the at least one label portion with the label liner, the label winding device comprising:
a waste winder for winding the separated waste portion;
a label winder for winding the at least one label portion with the label liner without the separated waste portion;
a waste guide for guiding the separated waste portion to the waste winder;
a waste guide installation portion in which the waste guide is slidably disposed;
a waste guide position sensor for detecting a position of the waste guide; and
a controller for controlling a winding torque of the waste winder and a winding torque of the label winder based on the position detected by the waste guide position sensor.

15. A printing system comprising:
the label winding device of claim 1 ; and
a printer for printing information on the at least one label portion of the label member.

16. A printing system comprising:
the label winding device of claim 14 ; and
a printer for printing information on the at least one label portion of the label member.
