【発明の名称】横型製袋充填包装機及びその制御方法
Document Type and Number:
Japanese Patent JP2801530
Kind Code:
B2
Abstract:
A horizontal form-fill-seal packaging machine (1) includes a former (4) for forming a film into a tubular configuration, a conveyor (5) for feeding articles into the tubular film one after another, a fin sealer (11) for sealing lapped edges of the tubular film, an end sealer (6) for sealing the tubular film in a crosswise direction thereof in a position between two adjacent articles, and a film feeding mechanism for feeding the film supplied from a film source (2) into the end sealer via the former and the fin sealer. A plurality of pushers (7) are mounted on the conveyor and equi-distantly spaced from each other in the feeding direction of the articles (W1). Each of the pushers defines the position of a rear end of the article. A length detector sequentially detects the length of the articles in the feeding direction. A controller controls the conveyor and the end sealer in response to the length of each article detected by the length detector. The controller controls the speed of the conveyor such that an equi-distant space is formed between each two adjacent articles. The controller controls the operation timing of the end sealer such that the end sealer seals the tubular film in substantially the central position of the space between two adjacent articles.
