Abstract
A case sealing system utilizes a parallel link mechanism with a built-in locking positioning system to support a case sealer such as a taper, gluer or stapler or the like at a selected height above a support table whereby the height of the sealer above the table may be readily adjusted to accommodate different height packages. Preferably, the system will also include a pair of easily adjusted side guides that are moveable to positions to center different width packages relative to the center line of the sealer so that the equipment may be quickly and accurately be positioned to accommodate different sized packages.
Claims13
A packaging machine comprising a frame, a support surface on said frame, an arm means, means mounting said arm means on said frame solely on one side of said support surface, said arm means being a parallel link mechanism composed with a pair of parallel arms, said means mounting including a first pair of spaced parallel pivotal connections a first of said pair of parallel connections pivotably mounting a first arm of said pair of parallel arms adjacent to one of its ends to said frame and a second of said first pair of spaced parallel pivotal connections pivotably mounting a second of arms of said pair of parallel arms adjacent to its end adjacent to said one end of said first arm to said frame, a support frame, a second pair of spaced parallel pivotal connections one for each said arm of said pair of parallel arms to pivotably connect its said arm to said support frame said second pair of parallel pivotal connections each being positioned adjacent to an end of its arm remote from said first pair of parallel pivotal connections, said parallel pivotal connections of said first and second pair of parallel pivotal connections permitting rotation of said arms about substantially parallel axes, locking positioning means interconnecting said pair of arms to releasably lock said arms in selected positions, a support beam mounted at one end to said support frame and extending as a cantilever from said support frame in a direction to project over said surface, a package closing means mounted over said surface on said support beam and control means for controlling said locking positioning means.
