The present invention is related to the field of roll polishers that are used to polish the surfaces of rollers that are used in manufacturing different types of sheet materials.
Rollers are used in various industries to produce flat smooth surfaces on various materials, such as for example, steel, copper, aluminum, brass, paper, plastics, or other like materials. In order to create the flat surfaces on these materials the rollers used during manufacturing should be free of defects and as smooth as possible. Roll polishers are often used to achieve and maintain the desired surface of the rollers used in manufacturing some materials.
Embodiments of the present invention relate to roll polishers that may be utilized with rollers in rolling stands that have restrictive space requirements. The roll polisher of the present invention comprises a tube with pivot actuators used to engage and disengage a rolling pad on the surface of a roller. Transverse actuators may be located at least partially within the tube, or in other embodiments located outside of the tube, and are used to move the tube, and thus, the rolling pad, transversely back and forth across the surface of the roller. The roll polisher may operate in an envelope that is as small as 11 inches by 9 inches and span rollers from 50 to 120 inches wide. The pivot actuators may apply a force of approximately 100 lbs. to the rolling surface to remove defects and smooth the surface of the roller. In other embodiments the roll polisher my operate in envelopes that are smaller or larger than 11 inches by 9 inches or outside of the width of 50 to 120 inches.

The following description and the annexed drawings set forth certain illustrative features of the one or more embodiments. These features are indicative, however, of but a few of the various ways in which the principles of various embodiments may be employed, and this description is intended to include all such embodiments and their equivalents.
The accompanying drawings illustrate embodiments of the present disclosure, in which:
Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

As illustrated in
The roll polisher 1 may be operatively coupled to the roll stand 4, or other support structure adjacent the rollers 2. In some embodiments the support mounts 40 may be operatively coupled directly to the roll stand 4 or other support structure adjacent the rollers 2. As illustrated in
As illustrated by
In operation, as the pivot actuators 20 are moved into engagement with the roller 2, a first end 132 of the polishing bar 30 may engage the roller 2 prior to a second end 134 of the polishing bar 30. Stresses on the pivot actuators 20 may be reduced or removed through the pivot coupling 31 because as the pivot actuators 20 extend the first end 132 of the polishing bar 30 may contact the roller 2, and thus, the pivot coupling 31 may allow the pivot actuators 20 to tilt or rotate to prevent damage to the pivot actuators before the rest of the polishing bar 30, including the second end 132 of the polishing bar 30, contacts the roller 2.
As illustrated by
In order to assemble and use the roll polisher 1 within the tight tolerances of the of rolling stands 4, in some embodiments of the invention the roll polisher 1 may be assembled according to the roll polisher assembly and use process 200 of
As illustrated by block 206 of
As illustrated by block 210 the transverse actuator 50 is operatively coupled to the tube 10 (either on the inside or outside of the tube 10). In the embodiments in which the transverse actuator 50 is located within the tube 10, the transverse actuator 50 includes, or is coupled to, an actuator tab 58. The transverse actuator 50 is positioned within the tube 10 through the tube opening 16, and the actuator tab 58 is utilized to operatively couple the transverse actuator 50 to a transverse actuator mount 54 that is located on the tube 10. In the embodiments in which the transverse actuator 50 is located outside of the tube 10, the transverse actuator 50 is operatively coupled to the transverse actuator mount 54, such as directly to the transverse actuator mount 54 or secured within an aperture in the transverse actuator mount 54. As illustrated by block 212 each of the support bars 90 of the support mounts 40 are operatively coupled to the first end 12 and second end 14 of the tube 10. In this embodiment, the support bars 90 are not coupled to the support plates 92 of the support mounts 40. For example, in an embodiment in which the transverse actuators 50 are located at least partially within the tube 10, the support bars 90 are inserted into the hollow ends of the tube 10, and the transverse pin mounts 46, which are operatively coupled to the end of the support bars 90, are operatively coupled to the transverse actuator pin 52 of the transverse actuators 50.
As further illustrated by block 214 of
After the receiving plates 80 and the support plates 92 are assembled and in the proper position, the assembled tube 10 with the support bars 90 assembled into the tube 10 is lifted into the proper orientation with the polishing bar in an extended engaged position with the surface of the roller 2. As such, the tube 10, the support bars 90, and the polishing bar 30 are located in the proper position for installation. The ends of the support bars 90 are then welded to the support plate 92 in order to orient the roll polisher 1 in the desired orientation. This assembly procedure allows for the assembly of the roll polisher 1 in the desired orientation to allow the polishing pad 130 to engage and disengage the polishing pad 130 with the surface of the rollers 2. In other embodiments of the invention instead of welding the support bars 90 to the support plates 92 to create the support mount 40, the support bars 90 may be coupled to the support plates 92 using couplings, or other like means. This may allow the positioning of the polishing pad 130 with respect to the surface of the roller 2 to change in order to properly locate and orient the roll polisher 1. As illustrated in
After the roll polisher 1 is installed the hydraulic or pneumatic couplings may be attached to the pivot actuators 20 and transverse actuators 50. In other embodiments of the invention the hydraulic or pneumatic couplings may be operatively coupled to the pivot actuators 20 and transverse actuators 50 before the roll polisher 1 is installed in order to engage the rolling pad 130 with the roller 2 before the support bar 90 is operatively coupled to the support plate 92.
When the roll polisher 1 is installed and the actuators are connected to the control system, the pivot actuators may be actuated into place in order to engage the rolling surface of the rollers 2, as illustrated by block 220 of
