US 4,223,850 A · Surface wind batcher and method of collecting material in roll form

Abstract

An improved surface wind batcher and method of collecting material in roll form while maintaining positional stability of the roll during its rotation comprising a pair of rotatably driven parallel side-by-side spaced support rollers which support and peripherally drive a roll of web material fed thereto in continuous length form. The rollers are mounted in movable bearings operated by pneumatic pistons which are automatically actuated during roller and roll rotation to increase the distance between the support rollers and thereby ensure positional stability of the rotating roll on the support rollers. Upon completion of roll formation, the support rollers are actuated to automatically doff the roll of material therefrom and return them to initial closely spaced position for formation of another roll.

A surface wind batcher for collecting an indefinite length web of material in roll form comprising a support frame, a pair of side by side, spaced, parallel support rollers having support shaft means and being mounted on said frame for engaging spaced undersurface portions of a roll of material across the full width thereof to support the roll therebetween, drive means for rotating each of the support rollers to impart rotation to the roll of material through surface engagement with the roll to build the diameter thereof;

and roller adjusting means including fluid actuated piston means mounted on said frame at each end of said rollers, bearing means attached to each of said piston means for movement thereby, each of said bearing means supportably engaging a respective end portion of said shaft means of said roller to permit rotation of said shaft means therein, and to move said rollers in rectilinear directions to increase or decrease the distance between the rollers and maintain positional stability of the roll on the rollers.

A surface wind batcher for collecting a web of material in roll form comprising a support frame, a pair of support rollers, bearing means mounting said rollers on said support frame for rotation about their central axes and in side-by-side, spaced, parallel relation to engagably support a roll of material along its width therebetween;

drive means for rotating said rollers to impart rotation to a roll of material therebetween, said drive means including motor means, first driven means interconnecting said motor means to one of said rollers to impart rotation thereto, and second driven means interconnecting said one of said rollers to the other of said rollers to impart rotation thereto;
fluid-actuated means mounted on said frame and attached to said bearing means for moving said bearing means and rollers during their rotation to increase or decrease the distance between the rollers;
and means for automatically sensing the amount of revolution of said rollers and for varying fluid pressure supplied to said fluid actuated means to move said rollers to vary the distance therebetween in response to a predetermined amount of rotation thereof.
