MACHINE FOR POLISHING ROLLERS, SUCH AS USED IN PRINTING MACHINES Filed May 9,y 1938 3 Sheets-Sheet 5 Patented June 4, 1940 N UNITED STATES PATENT OFFICE MACHINE FORl POLISHING ROLLERS, SUCH AS USED IN PRINTING MACHINES This invention relates to machines for polishing and buing hollow rollers, such as the printing rollers of fabric and paper printing machines, and has for its objectto provide a simple and convenient means by which the two operations of polishing and bufng can be readily performed in the machine without altering the setting of the roller being operated upon.
A machine in accordance with this invention comprises means for polishing and buing hollow rollers, such as printing rollers, comprising means for supporting and rotating the roller to be polished and buffed, a slide reciprocated in a path parallel with the axis of `the roller, and a swivelling head mounted upon the said slide, a column upon the said swivelling head and a counter- Weighted slide movablevertically along the said column and carrying an electric motor driving a bufng wheel at one end of its spindle and a belt pulley at the other end of a spindle, a polishim;r belt being placeable around this pulley and around a further pulley upon an arm pivoted to the swivelling head for pivotal movement in a vertical plane.
In one position of the head, the bung wheel engages the roller with its axis at right angles to the roller and is traversed b'ack and forth from end to end of the roller. In another position of the head at right angles to the bufng position, the polishing belt which extends between the two pulleys before referred to moves in Contact with the roller at right angles to its axis and traverses from end to end of the roller. A polishing stone may be mounted upon and below the arm before referred to and used to finish theroller, the polishing belt being used simultaneously or removed during stoning Referring to the accompanying explanatory drawings- Figure 1 shows one `convenient construction of amachine in accordance with the invention in front elevation, part of the machine being broken away to show` other parts, during the bulng operation.
Figure 2shows the machine in plan,
Figure 3 is a cross-sectional elevation on the line 3 3 of Figure 1.
Figuresl 4 and 5 are detail views showing the arrangements `for polishing and stoning respectively,` Figure 5 showing a modified form of the machine shown in the other gures.
, Figure 6 is a sectional elevation on the line 6 6 of Figure 2.
printing roller e which is to be treated is mounted. The headstock and roller are rotated by a rope drive f from the electric motor y.
A further motor h through a rope drive i, pinion y', idler lc adjustably mounted on a pivotally 5 movable arm l and gear Wheel m drives a feed screw n. By replacing the pinion y' on gear wheel `m by others of a different diameter and adjusting the position of the idler k, the rate of rotation of the feed screw n can be varied. The feedscrew n traverses a slide o along the length of the roller e. 'I'he slide o carries an arm p which engages collars q adjustably mounted on a stationary rod r at the ends of the traverse of the slide o and actuates reversing switches (not shown) controlling the motor h, thereby reversing the direction of movement of the slide.
Upon the slide o is mounted a swivelling head s which can turn about the pivot t and carries a column u whereon is a vertically movable slide v which can be adjusted in height by a lead screw w turned by ahandwheel Upon the vertically movable slide c is mounted an electric motor y driving a buffng wheel 2, mounted upon an extension of the motor spindle and formed of fabric layers, which engages the surface of the printing roller e and buffs it as it is traversed from end to end along the rotating printing roller. The height of the slide c is adjusted to suit the diameter of the roller e.
Upon the other end of the spindle of the motor y is a belt pulley l. 'Ihere is an arm t pivoted to the slide o for movement in a vertical plane and partially supported by a counterweight 3a attached to the arm 8 by cords running over pulleys 8b. lThis arm 8 carries a further belt pulley 9. A polishing belt lll can be placed over the pulleys 1 and 9. On turning the swivelling head s through 90 from the Figure 1 `position and lowering the pivoted arm 8, the polishing belt l0 engages the printing roller e as shown in Figure 4 and polishes it. A spring-pressed plunger Il engages in one or the other of two holes l2 in the slide Q` and holds the swivelling head s in its desired position.
It will be noted that the polishing in Figure 4 is moving at right angles to the axis of the printing roller e and at right angles to the direction of movement of the surface of the buffing wheel e in Figure 1.
Raising the pivoted arm 8 slackens the polishing belt I0 and enables it to be readily removed from the pulleys 'l and 9.
If it is desired to stone the printing roller belt surface the mcdlned fom of the machine shown in Figure 5 may be employed. It will be seen that there is a rotary polishing stone I3 mounted upon and below the pivoted arm 8. The shaft I1 whereon' the stone I3 is mounted runs in a' sleeve Il mounted in trunnions I9, so that the stone may be set at the correct angles to the roller axis and clampedat this angle by the set-screw 20. Loose weights 2i rest upon the top of the sleeve II and apply the correct pressure for stoning through the thrust bearing 22. The shaft I1 is driven by a belt 23 from the pulley 24, which in turn is driven from the motor y. l
The stone may be stationary instead of rotary if desired. f i
A n overflow trough I5 supplies lubricant during the `stoning operation, the lubricant and the particles removed from the roller rsurface being received in the large blower trough I6.
What I claim is: i A machine for polishing and bumng printing and other hollow rollers comprising means for supporting and rotating the roller about a horizontal axis, a slide movable parallel withthe axis of the roller, means to reciprocate said slide, a head mounted to swivel about a vertical axis upon said slide, a column lupon the said swivelling head, a slide vertically movable upon said column, means to move said slide along said column and to retain it in desired position thereon, an electric motor upon said column slide, a bum-ng wheel at one end of and driven by said motor, a belt pulley at the other end of and driven by said motor, a counterweighted arm pivoted to said column slide for movement in a vertical plane, a belt pulley at the free end of said arm, and an endless polishing belt around the two said belt pulleys.
