3,003,411 GUIDEWAY CONSTRUCTIONS FOR V BALING PRESSES Sebastian F. Judd, 4473 N. 100th St., Milwaukee, Wis.
Filed Sept. 23, 1958, Ser. No. 762,851 3 Claims. (Cl. 100-98) 3,003,411 Patented Oct. 10, 1961 faces the hopper opening is short to expose the corner of the knife 19 which is therebelow, and is equipped with set screws 20. Adjustment cap screws 21 have their lower ends threaded into the knife element and set screws 21' are adapted to bear on top of the knife element 19. By manipulating the screws 21, the knife element may be pulled up, the screws 21' being operable to push the knife in a downward direction. The screws 20 lock the knife in a desired position of adjustment. The screws 21 ex tend loosely through holes in the marginal member 17. Projecting outwardly or rearwardly from the housing 1 portion 10 are upper and lower rods 22 which have theiring action be maintained to prevent troubles such as I jamming of the machine. Thus, maintaining of the shear-, ing relationship has presented problems because with prior constructions wear between the relatively movable parts, and particularly between the ram and its guideway, has created changes in the relationship between the shear! ing knives to impair the shearing action. i
It is a general object of the present invention to provide a construction wherein a proper shearing action may be maintained as long as possible.
A more specific object of the invention is' to provide novel means for guiding .the horizontal movement of the compressing ram whereby the knife at the front of the ram may be guided into correct shearing relationship with the stationary knife.
outer ends supporting a head 23. Projecting inwardly from the head 23 is a stationary piston rod 24 which co-' acts with an hydraulic cylinder 25, the latter being connected with a ram 26. At the inward or forward upper edge of the ram 26 is a shearing knife element 27 which; is adapted to coact with the V-shearing knife element 19. Suitably supported for movement with the ram 26 and cylinder is a closure plate 28 for the hopper opening. Thus, when the ram is projected to its forwardmost 1 position, the plate 28 will close the bottom of the hopper Y Afurther object of the invention is to provide a con- 7 struction as above describedwherein the guideway includes wear strips which are adjustable in a novel manner to correct wear at the place where the wear occursand maintain a proper shearing relationship between the knife elements.
A further object of the invention is to provide a guide way construction as above described, including means for lubricating the guideways.
With the above and other objects in View, the invention consists of the improved guideway construction for baling presses, and all of its parts and combinations as set forth in the claims, and all equivalents 'thereof.
In the accompanying drawings in which the same refer ence numerals designate the same parts in all of the views: a
FIG. 1 is a horizontalsectional view through an improved baling press looking in a downward direction;
FIG. 2 is a sectional view taken on the line 2-2 of FIG. 1;
FIG. 3 is a sectional view taken on the line 3-3 of FIG. 1;
FIG. 4 is a fragmentary transverse vertical sectional view through a guideway portion;
FIG. 5 is a fragmentary top view of the press looking down through the hopper; and
FIG. 6 is a fragmentary side elevational view showing the mechanism of FIG. 5. V
Referring more particularly to the drawing, the improved baling press includes a main housing 10 forming a charging box and having side members 11, having a bottom 12, and having a top' 13 (see FIG. 2), provided with a receiving opening 14. The receiving opening 14 is surrounded on three sides by an upstanding rim 15 which receives the bottom of a hopper 16, as indicated by dot and dash lines in FIG.' 2. At the trailing edge of the hopper opening there is a marginal member 17 which is V-shaped in plan view, as shown in FIG. 5, with a downwardly facing transverse groove 18 for receiving a staopening 14.
Referring now to FIGS. 3 and 4, it will be seen that the inner faces of the side members 11 are provided with' longitudinal grooves 29, within which male guideway elements 30, having outer portions which are V-shaped in cross section, are adjustably positioned. Each guide; way has obliquely angled and converging upper and lower faces 31 and 32 to which replaceable wear strips 33 of high manganese carbon steel are detachably se cured. Cap screws 34 have their inner ends threaded into the guideway members 36 so that by adjusting the screws in -a suitable direction the guideway elements 30 may be pulled inwardly of the grooves 29. Set screws 35 are also threaded into the side wall and are adapted to bear against the guideway elements 30 to exert a pushing force thereon, there being lock nuts 36 to set the screws in a desired position. By suitable manipulation of the screws 34 and 35, the elements 30 with the attached wear strips may be moved within the grooves 29' according to the adjustment desired. By referring to FIG. 6 it is apparent that there are a plurality of screws throughout the length of the guideways so that certain portions may be moved more than other portions to' produce an angular adjustment to compensate for greater wear in certain places, and this is usually near the forward end of the machine.
The male guideway elements 30 coact with ti-grooves 37 in the sides of the ram 26, said V-grooves forming female guideway elements and having tapered longitudinal faces to match the angles of the faces 31 and 32 of the male elements 30. The faces of the grooves 37 are equipped with wear strips 38 which contact the wear strips 33 of the male elements 30. Thus, as the ram 26 is moved by the cylinder 25, it is guided by the ways 30 and 37 which keep the ram in the desired alinement This therefore permits the maintenance of a proper cut ting relationship between the knife elements 27 and 19, and as before mentioned, whenever any wear does occur, this can be readily taken care of by manipulation of the adjustment screws 34 and 35 and by adjustment of theknife element 19. v
In order to keep this wear to a minimum, suitable lubricant from a reservoir 39 is caused to how through conduits 40 leading to both sides of the machine. Thesef I conduits communicate with ducts 41' shown in FIG. 4'
tionary knife element 19. The wall of the groove which in the male guideway elements 30 to conduct the lubricantto the operating faces of the upper wear strips 33 and 38. The inner end of each of the lubricant lines is fitted with a nozzle 40 which fits loosely through holes 41 in the engaged by an upstanding lug 45 (see FIG. 2) movable with a'carriage 46, the latter being supported onthe stuffing box 47 of the hydraulic cylinder 25 so as to be movable with the cylinder and ram 26. The carriage has wheels 48 which ride on the upper rods 22. Thus, Whenever the ram is near the end of its inward movement, the lug 45 engages the lubricator push rod 43' to causea shot of'lubricant to flow through the pipes '40.
Projecting from one side of the charging box '10 near the compacting end is an hydraulic cylinder'50 (see FIG.
set screws 20. The male guideways are then adjusted by means of the screws 34 and 35. Turning of the screws 35 forces the elements 30 inwardly, and turning of the cap screws 34 pulls the elements. 30 outwardly. Due to the cooperating tapered surfaces of the male and female guideway elements, the vram .is forced up or'do'wn slightly during adjustment. .Such upward adjustment is possible after wear occurs on the upper wear strips 33 and 38 in i order to compensate for said wear, the wear permitting 1) having an extensible piston rod 51 carrying a ram 52.
This ram is adaptedto act on material in the space (a) after said material has been compressed by the main ram 26. Another hydraulic cylinder 53 suitably supported from the opposite side of the machine opposite the cylinder 50 carries an'extensible piston rod '54 which has a ram 55 onits outer end.
' Operation 7 :ASsuming that the guideway elements and knife element 19 are in properadjustment to provide for a proper shearing relationship, to start the baling cycle the mate- 7 rial to be baled is lowered into the hopper 16. Some of thematerial will fall into the charging box 10 and some will remain in the hopper. Next, through a manual or automatic control, hydraulic fluid is caused to how into the cylinder to force the cylinder to the left, referring to'FIGS. 1 and 2. As the ram .26 moves forwardly any material that is partially in the charging box and partially in the hopper is cut off by the shearing knives 19 and 27. This permits hopper feeding and obviates the necessity of forcing all of the material into the charging box before starting the baling cycle. .As the ram continues forwardly the door 28 which is fastened to the ram 26 closes the hopper opening ,14, preventing any material in the hopper from dropping into the charging box behind the ram 26. Thus, the hopper discharge opening is closed during all parts of the baling cycle except during loading, so that the hopper may be filled at any time. As the ram continues, it compresses material in the space (a). Thereafter, the ram 52 is actuated either manually or by an automatic control to push transversely against the material in the space (a) while the latter is confined between the end of the ram 26 and the inner face 56 of the end wall of the charging box (see FIG. .1). This material is thus compressed against the ram 55. Thereafter, either through manual or automatic control, the ram 55 is allowed to back out under pressureof the ram 52,. with the latter continuing. its movement until it reaches the end of its stroke at the opposite side of the box, at which time the compressed bale will be'entirely out of the baling box and will be held between the rams 52 and 55 over the space (b). Thereafter, through manual or automatic control the ram 52 starts withdrawal movement, with ram 55 staying stationary. This re leases the squeeze on the halo and it drops onto the ground or onto a conveyor through the space (b). The
ram 52 continues its withdrawal movement until it returns to the position of FIG. 1, at which time the rams 55 and 26 start returning to their home positions. As the ram '26 passes the stationary knife 19 the bottom of the hopper opens and the material in the hopper is allowed to fall into the charging box. When the ram 26 reaches the end of its return stroke, the filling of the box is again complete. The cycle then starts once, more. to bale the material which has just been dropped into the charging box. v
Before the press can be operated properly, the shear knives must be properly adjusted. As before mentioned,
. this can be accomplished by adjustment screws 21 and 21" with the knife '19 held in adjusted position by the a compensating inward movement, There is, of course, a slight clearance between the lower wear strips 33 and 38 which permits inward adjustable movement of the 'guideway elements 30. Withsuch clearance the actual support of the weight of the ram is borne by the upper wearfstrips 38 and due to the oblique angles of the contacting wear strips, when the block is adjusted inwardly of its groove 29 the ram 26 .is lowered and when the block is adjusted outwardly of its groove 29 the ram 26 is raised. When the adjustment is correct the screws 35 are locked by the nuts 36 and the cap screws '34 are pulled tight so that they cannot "move. This adjustment should be .so made that there is only a few thousandths of an inch clearance between the wear strips of the guideway elements and the female grooves 3-7. Since the guideway elements are in a straight horizontal line, it is insured that theram will ride in a true horizontal plane, and such movement of the shear knife 27 is also insured.- After the way adjustment has been completed, additional knife adjustment maybe made until there is just a little more clearance between the knives than there is between the guideway elements. This excess clearance will prevent the .knives from striking. All wear due to forward or backward movement of the ram 12ers taken by the wear strips 33 and 38- Inasmuch as these strips areof wear resistant material and are lubricated, wear is kept to a minimum. Whenever wear does occur, it can be compensated for by adjustment of the male elements 35?. Inasmuch as the most wear occurs at the forward end, quite often an angular adjustment of the male elements 30 is required. Due to the row of adjustment screws shown in FIG. 6, such angular adjustment can be readily accomplished.
Various changes and modifications may be made without departing from the spirit of theinvention, and all of such changes are contemplated, as may come within the scope of the claims.
