-3'Glaims. .11 This invention relates to ring and roller presses and more particularly to ring and roller presses of the type disclosedin Patent Number 2,229,1 i3 issued January2l, 1941, to M. J. stacom.
In a ring and roller press (of the type disclosed in the above mentioned patent the free floating rin operating between two rollers must have reed m of m men to llow it axi to i or fall according to the amount and/or character of the material fed into the press. At the same time the axis of the floating ring must be 50 constrained as to maintain it exactly parallel with the axis of the two rolls, both of'which must be parallel to each other. If the axis of the ring fails to remain parallel to the axis of the rollers, the surface of the ring will then follow a helical path along the surfaces of the rolls and thus, as it turns it will be translated axially by means of friction forces actin at the lines .of contact between the ring and rolls, unless such movement is restrained.
As disclosed in Patent Number 2,229,142 issued to J tacom. Januar .2 4 2 sonic-e p essed side plates are provided to maintain the ring and roll in alignment, and in other instances flanges were provided on the ring and rolls for the same purpose, however it-has'beenfound that the friction forces between the ring and rolls often are so great as to damage or rupture the flange, or render the side plates inefiective before the pressure on the face of the flange or plates returns the ring to its axial alignment.
It is an object of the present invention to pro.- vide practical means to maintain alignment of the ring and rolls which will not be subject to rupture or other disabling effects by the great friction forces between the ring and roll and which will return the ring to perfect alignment if its axis should happen to be tipped and having re-established alignment, will tend to maintain it.
With these and other objects in view, as may appear from the accompanying specification, the invention consists of various features of construction and combination of parts, which will be first described in connection with the accompanying drawings, showing a roller press of a preferred form embodying the invention, and the features forming the invention will be specifically pointed out in the claims.
In the drawings:
Figure 1 is a side elevation of a ring and roll press showing the alignment maintaining means thereon.
Figure 2 is a perspective view of the alignment maintaining means.
Figure 3 is a section through the alignment maintaining means.
Referring more particularly to the drawings Figure 1 illustrates a ring and roll press such as described and claimed in Patent Number 2,229,141, issued January 21, 1941, which includes a back up roll I, work roll 2 and a floating ring 3. The back up roll I and the work roll 2 are mounted for rotary movement on shafts 4 and 4 having iixed axes of rotation, While the ring 3 is free to move or dip during rotation imparted thereto by frictional engagement with the roll 'I in accordance with the amount and character of the material fed to the press, all in the manner as set out in the above mentioned patent :and in Patent Number 2,374,047, issued April 1'7, 1945.
'While the floating ring 3 is free to dip or change the plane of its axis during operation,fit is necessary to maintain its axis in perfectparallelism with the axes of the rolls I and 2 to insure proper operation of the press, maintain uniform pressure across the blanket of material passing through the press and insure against injury to the press parts and for the purpose of maintaining such parallelism means shown specifically in Figures 2 and 3 of the drawings is provided.
The alignment maintaining means comprises a roller [0 rotatably mounted on a shaft H. The shaft II is carried by a supporting bracket [2 which is in turn pivotally supported by a pivot pin 13 from a stationary bracket I4. The bracket M is rigidly connected to the supporting frame 5 of the press.
The roller HI has annular flanges 15 formed on its perimeter at its ends and these flanges engage in sidewise engagement against the edges of the ring 3 as is clearly shown in Figure 2 of the drawings.
The stationary bracket M has a cylinder l6 formed therein or carried thereby in which is mounted a piston ll. Pressure fluid from the pressure accumulator shown in Figure 1 of Patent 2,374,047 or from any other suitable source (not shown) is delivered into the cylinder I6 behind the piston I! through an inlet [8 and urges the piston l1 outwardly against the end of the adjusting screw 19. The adjusting screw I9 is adjustably carried by the pivoted bracket I2 and thus the piston 11 urges the roller [0 into engagement with the perimeter of the floating ring 3 and maintains the flanges IS in engagement with the edges of the ring 3 during the operation of the press. The pressure exerted by the piston I! is sufiicient to maintain the engagement of the roller 10 and ring 3 regardless of the pressures exerted to disrupt such contact during the operation of the press.
In operation the alignment maintaining device or structure is placed so that it will engage the ring 3 a considerable distance in advance or ahead of the line of maximum application of pressure in the press, that is it is placeda considerable distance aheadof the lines of contact (indicated at 20) between the ring 3 and rolls and 2 when no material is being fed through the press.
The roller l acting on the sides of the ring 3 at such a considerable distance in advance of the line of contact, its pressure will return the ring to perfect parallelism of itsaxis with the axis of t the rolls 1 and 2 if the axis of the ring 3 should happen to be tipped, and having reestablished to engage the ring 3 substantially diametrically,
opposite of the point of engagement of the roller It with the ring 3.
The structure carrying the roller 2| and urging it into engagement with the ring 3 is the same.
as that shown in Figures 2 and 3 of the drawings. The roller 2| does not have flanges on its ends and it has only engagement with the perimeter of the ring 3 and it merely acts to counterbalance the radial pressure of the roller It so as to leave the ring 3, in efiect, complete freedom of action within its normal intended plane of rotation.
When the ring3 is rotated in the direction'indicated by the arrow A (see Figure 1) the roller H! is placed near the bottom of the press and the roller 2| near the top as is shown in Figure 1 of the drawings, but in the event the ring is rotated in the direction indicated by the arrow B (see Fig- 4 said ring, adjustable means establishing connection between said roller and said pressure actuated means, and a radial-pressure counterbalancing roller engaging said ring at a point substantially diametrically opposite of the point of engagement of the flanged roller and ring.
2. A roller press including a rotatable ring supported for movement between two rotatable rolls and normally having line contact therewith, an
alignment-maintaining roller having engagement with the perimeter of said ring in advance of the lines of contact of the ring and rolls, flanges on said roller and engaging the sides of said ring, a pivoted bracket carrying said roller, a pressure actuated piston acting upon said pivoted bracket to urge said roller into engagement with said ring, and'a radial pressure counterbalancing roller engaging said ring at a point substantially diametactuated piston acting upon said pivoted bracket ure 1) then the rollers llland 2| are interchanged so that the flanged roller IE) will always be in advance of the line of contact of the ring 3 and rolls and 2.
It will be understood that the invention is not 1. A roller press including a rotatable ring sup ported for movement between two rotatable rolls and normally having line contact therewith, a
flanged alignment maintaining roller engaging said ring in advance of the lines of contact of the ring and rolls, pressure actuated means acting upon said roller to urge it into engagement with rically opposite of the point of engagement of said alignment-maintaining roller and ring.
3. A roller press including a rotatable ring supported for movement between two rotatable rolls' and normally having line contact therewith, an alignment-maintaining roller having engagement with the perimeter of said ring in advance of the lines of contact of the ring and rolls, flanges on said roller and engaging the side of said ring,
