Description

  The present invention relates to a label sticking apparatus.

  As is well known, a shrink label can be attached to the surface of a packaged object such as a plastic bottle or bottle without using an adhesive, and can be peeled off from the surface of the packaged object simply by cutting it when separating waste. Therefore, today, when resources are actively recycled, they are used for packaging many products.

  Normally, when a shrink label is attached to a package, a flat tube-shaped shrink label formed by cutting a folded tubular film at predetermined intervals is opened in a cylindrical shape. After the cover is placed on the body, the shrink label placed on the package body is heated and thermally contracted to be attached to the surface of the package body.

  Accordingly, when the shrink label is put on the package body, if the shrink label is not positioned at a predetermined position of the package body, the shrink label is attached to the package body in a misaligned state. Therefore, it is necessary to keep the shrink label placed on the package body in a predetermined position on the package body until the shrink label is thermally contracted, and many mechanisms have been developed.

For example, in Patent Document 1 described later, a pair of stoppers for positioning a heat-shrinkable tube are provided at predetermined positions above a moving device that moves a bottle or the like in an upright state, with an interval substantially equal to the lateral width of the bottle or the like. A heat-shrinkable tube is provided by blowing compressed air from the fusible tube into the open end of a half-opened heat-shrinkable tube that is provided on the shoulder of a bottle or the like located below the lower fusible tube above the stopper. Is a heat shrinkable tube fitting device that expands into a circular shape and is blown down onto a stopper so that it fits in a predetermined position such as a bottle. And a pair of endless belts made of a flexible material whose interval is slightly narrower than the width of a bottle or the like.
