Rotary heat shrinkable label paper attachment device

Abstract

The present invention relates to a rotary apparatus for attaching a heat-shrinkable label, the apparatus comprising: a container in-feed / out-feed part for feeding containers, which are covered with the heat-shrinkable labels, in or out by a guide wheel; a rotary transfer part comprising a lower rotating shaft and an upper rotating shaft, which are uprightly provided so as to pass through a base table such that the containers fed in or out by the guide wheel are rotated and transferred, a turntable axially provided to the lower rotating shaft and having a plurality of rotary chucks rotating in a state in which the containers to be fed-in are loaded thereon, and an upper body axially provided to the upper rotating shaft; a clamping means which includes a plurality of lifting rods aligned in an annular form so as to be formed on a one-to-one basis with the rotary chucks of the turntable, clamp nozzles having spraying holes and formed at lower end portions of the lifting rods, and supply hoses coupled to the outer peripheral surfaces of the clamp nozzles so as to supply either air or cooling air, and opening and closing the mouth of the container, and filling the container with the air or cooling air through the spraying holes so as to prevent the deformation of the container during a label shrinking process by heat; and a steam deposition part provided on the opposite side of the container in-feed / out-feed part.

Description

technical field [0001] The present invention relates to a rotary heat-shrinkable label paper attaching device for attaching heat-shrinkable label paper to a plastic bottle. More specifically, it relates to the following rotary heat-shrinkable label paper attaching device: Shrink labeling by steam is possible, and the plastic container can be quickly labeled with high-temperature steam without damage such as shape deformation. Background technique [0002] Generally, plastic containers (PET bottles) are widely used as liquid beverage or food containers such as carbonated beverages, alcoholic beverages, fruit juice beverages, soy sauce, sauces, etc., by manufacturing thermoplastic polyester resins by blow molding. In particular, the material properties of plastic bottle containers are excellent in transparency, durability, chemical resistance, and elastic strength. Therefore, their utilization rate as containers for liquid food or chemical products is gradually increasing. ...

Problems solved by technology

[0012] In the rotary type label manual attaching device as described above, in the process of transferring the storage container in a rotary manner, the label paper is attached in a sticker type and the manual is attached by means of an adhesive, which is inconvenient when the storage container is used twice. Remove the label paper, and as mentioned above, the adhesive has the problem of being environmentally unfriendly to spray out according to environmental hormones,

[0013] Moreover, in the conventional technology, in the case of a rotary attaching device, the label paper can be attached by sticking or sticking, but in the case of applying shrink label paper, it is difficult to form a chamber for preventing heat loss. Therefore, it is difficult to apply shrink label paper to the rotary type
