HEAT-SHRINKING APPARATUS FOR SHRINK LABELS

Document Type and Number:

WIPO Patent Application WO/2015/199221

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a heat-shrinking apparatus for shrink labels which is capable of uniformly heat shrinking a shrink label covering a portion or the entirety of an article, and which is capable of completing heat shrinking in a state in which water drops are not deposited on the article and the surface of the shrink label. Accordingly, the present invention is provided with: a heat treatment chamber (2) having, provided therein, a steam discharge unit (12) for discharging superheated steam in order to heat shrink a cylindrical label (L) fitted to a container (PC), and a heated-air blowing unit (14) for causing deposited water drops to evaporate by blowing heated air on the container (PC) after the cylindrical label (L) has been heat shrunk; a superheater (22) which heats steam generated by a steam boiler (20), to generate the superheated steam; a preheating unit (27) which uses the surplus steam inside the heat treatment chamber (2) to preheat air used to generate the heated air; a heated-air-generating heat exchanger (15) which uses steam to heat the preheated air to a prescribed temperature; and a condensing heat exchanger (31) for condensing the surplus steam.
