Timing controller and packaging machine incorporating same

摘要

A vertical pillow type form-fill-seal packaging machine (10) with transverse sealers (40) incorporates a timing controller (50) for adjusting the timing for clamping a tubularly formed film with the sealers such that articles being dropped in to be packaged will not be caught in between. A display device (54) displays a time axis or parallel axes along which markers indicate the times of arrival of the falling articles to be packaged and the sealers at the clamping position for the sealers. As the user moves the marker for indicating the arrival time of the sealers, the timing controller (50) adjusts the operating mode of the sealers (40) such that the sealers will clamp the film at the time specified by the user according to the displayed time of arrival of the articles.
