Title:
FILM FEEDING-WINDING DEVICE FOR CONTAINER SEALING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/065598
Kind Code:
A1
Abstract:
The present invention relates to a film feeding-winding device for a container sealing apparatus, wherein film feeding-winding device is applied to a sealing apparatus for sealing the upper end of a container such as a beverage cup, a food container, etc. with a film, and minimizes manual operations during installation of a film in the sealing apparatus and facilitates a replacement operation of a film roll. The present invention provides a film feeding-winding device (12) for a container sealing apparatus (1), wherein the film feeding-winding device (12) is provided in a housing (11) of the container sealing apparatus (1) and comprises: a circulation track (121) including a pair of left and right belts (1211) that are spaced apart from each other, and pulleys (1212) installed on rotary shafts (1213) that are respectively arranged on inflection points of the belts (1211) and are coupled to the wall surface of the housing (11); and a guide bar (122), which is a bar member having a length corresponding to the spaced distance of the circulation track (121) and has a gap (1221) that is split from one end portion to a point before a certain distance from the other end portion. The guide bar (122) is coupled across the outside of the pair of left and right belts (1211) while a film (22) unwound from a film roll (2), which is arranged outside the circulation track (121), is inserted in and held by the guide bar (122) in the width direction thereof, and thus, the film (22) is fed onto the circulation track (121) when the guide bar (122) moves along the circulation track (121). After feeding the film (22), the guide bar (122), in which the film (22) is inserted and held, is separated from the belts (1211) and then is coupled to be the central axes in the left and right pulleys (1212) which are at certain inflection points of the circulation track (121), and thus, the film (22) is configured to be wound through the axial rotation of the guide bar (122).
