Description

  The present invention relates to a label sticking apparatus, and more particularly, to a label sticking apparatus that peels off a label temporarily attached to a belt-like mount and sticks it to an adherend.

  For label affixing devices that peel off the label temporarily attached to the belt-like mount and attach it to the adherend, a plurality of labels are temporarily attached to the belt-like backing at intervals in order to feed out the label to be attached to the adherend. A supply reel for loading the label continuous body, a transfer means for transporting the label continuous body from the supply reel, and a take-up reel for winding the belt-like mount from which the label has been peeled off. In some cases, each nip roller is pressed using a transfer roller for transferring a continuous label body on which a label is temporarily attached and a transfer roller for transferring a belt-like mount from which the label has been peeled off (see, for example, Patent Document 1). .

However, in the conventional technology, in a label sticking apparatus having a structure in which a belt-like backing sheet is pressed and transported to one transfer roller by two nip rollers, a label continuous body is loaded on a supply reel, and a belt-like shape is formed on a take-up reel via a peeling plate. To set the mount, if the label continuity between the nip rollers becomes slack, the label will not be peeled off from the strip mount as a peeling failure, or the strip mount will be applied with an appropriate pressing force to the release plate. There was a problem that peeling did not occur and contact failure occurred.
