When a plant runs six formats a week, changeover time decides profitability more than rated speed does. Three mechanisms cut it on Guorun machines.
Glue graphics are imported as files. The operator recalls the pattern for a returning format instead of setting it again, which is why Guorun quotes around five minutes per product change on the semi-automatic machines.
Bottomless, enclosed and bottomed inner boxes are handled by switching the four-corner device mode. There is no tooling to find, fit or store.
The one-time automatic bubble pressing system does not need a module change between formats, removing another mechanical step from the changeover.
Record the spray pattern file name, the corner device mode and the envelope settings for each format. A changeover that takes five minutes on the machine can still take thirty if nobody wrote the setup down.
Single-station semi-automatic rigid box assembly machine that sprays glue on side panels and flat surfaces, takes shells up to 850 x 450 mm and changes over in about five minutes.
Two-station semi-automatic rigid box assembly machine covering shells up to 950 x 550 mm, with separate size envelopes for single and dual station work.
Guorun quotes about five minutes per product replacement on the GR-600B and GR-1000B, including importing the spray pattern.
Not necessarily faster, but more repeatably, because the servo linkage returns to the same positions rather than being reset by hand.
