ABSTRACT:

TECHNICAL FIELD
This invention relates to a label dispenser in which each of printed adhesive labels in a roll-shaped label continuum can be stuck on an article to be stuck by moving either the label or the article, or by peeling the label manually.
BACKGROUND ART
A conventional label dispenser for sticking printed adhesive labels on articles to be stuck, set forth, for example, in Japanese Patent Preliminary Publication No. Hei 6-99963, like a printing labeler, needs a manual holding operation with a grip and a main lever to peel each of adhesive labels from a mounting sheet so that the label is on standby for its adhesion to an article. Furthermore, this label dispenser is such that a peeled part of the label is pressed against the article by a label sticking section, and the label is pulled (moved) forward in such a way as to rub the surface of the article by the label sticking section and thereby is stuck on the article. In particular, a continuous sticking operation of the label dispenser forms the cause of an operator's fatigue. Still further, because of the structural restriction of the label dispenser, there is a limit to the amount (length) of the label which is required to peel and transfer the label from the mounting sheet by the holding operation. Hence, the label dispenser cannot accommodate labels, each having some degree of length.
It is, therefore, an object of the present invention to provide a label dispenser in which, when an adhesive label is stuck on an article to be stuck in such a way that a mounting sheet of a roll-shaped label continuum on which a number of printed adhesive labels are temporarily stuck in succession is pulled by a winding section with a motor as its drive source (namely, when the label is completely removed from the mounting sheet) before the tip of the next label is automatically peeled from the mounting sheet so that the label is placed on standby for its adhesion to an article and a peeled part of the label is pressed against the article by a label sticking section so that the label is stuck on the article by moving either the label or the article, or when the label is manually pulled out and stuck on the article, the mounting sheet can be pulled automatically even though the mounting sheet is separated from a turn section in accordance with the transfer of the label (namely, even though the mounting sheet is slack) until the label is completely removed from the mounting sheet (that is, while the label is temporarily stuck on the mounting sheet).
DISCLOSURE OF THE INVENTION
The label dispenser of the present invention is designed so that a mounting sheet of a roll-shaped label continuum on which a number of printed adhesive labels are temporarily stuck in succession, is pulled by a winding section with a motor as its drive source on the downstream side of the travel of the mounting sheet passing a turn section. The label dispenser includes a label detecting means for ascertaining whether a label peeled from the mounting sheet is present; a mounting sheet slack detecting means for detecting the slack of the mounting sheet traveling in accordance with the transfer of the label until the label is completely removed from the mounting sheet when a peeled part of the label is pressed against an article to be stuck by the label sticking section and either the label or the article is moved to stick the label on the article or when the label is pulled out manually; a control circuit for driving the motor to pull the mounting sheet by the winding section when the mounting sheet slack detecting means generates a mounting sheet slack detecting output and even when the label detecting means generates a label absence detecting output and a timer circuit which, when the label detecting means is turned to a state of a label presence detecting output, causes the drive of the motor to be continued for a predetermined time, which time is adjustable.
