Title:
SEALING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/032398
Kind Code:
A1
Abstract:
This invention addresses the problem of providing a sealing apparatus that makes it possible to: enhance the operability, workability, and safety of initial cover film positioning compared to the prior art; prevent cover film and the apparatus interior from becoming unclean and having foreign matter adhere thereto; and accurately position such that cover film is not wasted. To solve this problem, a sealing apparatus (10) is made to comprise a sealing unit (42), a feed roller (54) that is provided between a mounting part (30) that a cover film (26) is mounted on and a cutter (50) and is capable of moving the cover film (26) forward and backward, a first sensor (64) that is capable of detecting a distal end part (26a) of the cover film (26) on the downstream side of the feed roller (54), and a control unit (62), and the control unit (62) uses position information from the first sensor (64) to carry out control for cutting the cover film (26) after drawing the same out to a position at which the distal end part (26a) is beyond the cutting position of the cutter (50) by a prescribed length.
