sum 3 BF 3 INVENTOR Dominick M.Aluo'rro ATTORNEYS VERTICAL-HORIZONTAL BALING PRESS SUMMARY OF THE INVENTION The baling press is intended to bale scrap or waste materials such as wastepaper, corrugated paper, cardboard, cartons, newsprint, magazine trim, rags and other waste materials.

The press has a horizontal frame structure with a baling chamber section at its left end and a hydraulic cylinder at its right end and spaced from the baling chamber. A roof structure extends lengthwise of the framework, particularly at the central section beneath which there is a loading pit, the roof structure advantageously extending continuously from end to end of the baling press.

The pit section also includes a steel supporting framework and it has a right-hand wall which is in approximate vertical alignment with the plunger on the piston of the hydraulic cylinder when the plunger thru the piston of the hydraulic cylinder when the is in its retracted position. The opposite end wall of the pit section is in vertical alignment with the entrance to the baling chamber.

The lifter, which as indicated previously. is of special construction, has a bottom wall and opposed sidewalls attached to the side edges of the bottom wall thus forming a structure which is U-shaped in cross section. With the end walls of the pit the lifter forms a chamber within which the material to be baled is partially compressed by the coaction of the lifter bottom and side walls, the pit end walls and the roof structure. The lifter is raised until its bottom is level with the bottom of the baling chamber. This partially compressed material is then further compressed by the operation of the plunger which moves the material lengthwise of the elevated lifter and into the baling chamber. After a number of repetitions of the com-. bined vertical and horizontal compressions just described the baling chamber will be filled, and the conventional wires are placed about the bale. These wires are threaded through spaced horizontal parallel grooves provided in the vertical face of the plunger and then carried around the bale.

DETAILED DESCRIPTION Referring to FIGS. I and 2 the baling press comprises a frame structure having upper horizontal channel members I and 2 at the front and rear of the baler respectively. Parallel to these members are front and rear angle members 3 and 4 at the level of the loading floor 5. Supportedv within the framework at its right end portion or section there is a hydraulic cylinder 6 having a plunger 7 at the left end of piston rod 8. Cylinder 6 is operated by means of a fluid pump 9 which is connected through control valves (not shown) to the opposite ends of the cylinder by hose members 10 and II. The plunger 7 is supported not only by piston 8 but also by a pair of rollers 12 which are rotatably mounted on a cross rod at the upper end of a short bar 13 (FIG. 2) which is welded centrally at the upper side of the plunger. These rollers 12 travel along a pair of rails 14 in the form of channel bars which are supported on the framework midway between the front and rear frame channels I and 2. At the left end of the framework there is a baling chamber l5 which will be referred to more in detail below.

The upper front and rear top frame members I and 2 are supported by pairs of front and rear vertical steel posts I6, I7, I8 and I9. A roof member shown as a flat steel plate extends throughout the length of the frame structure from one end to the other of the top channel members I and 2. It is provided with a central lengthwise slot 21 (FIG. 2) which allows for the travel of plunger 7 and through which the short bar I3 for the supporting rollers 12 projects.

The two vertical steel posts 17 are located adjacent the right end of the pit which may be designated by numeral 22. The two vertical posts 18 are at the left end of pit 22 and form the entrance to baling chamber 15. The roof of baling chamber 15 is formed by plate 20, and the bottom by a somewhat similar but shorter plate 23 which may be seen in FIG. 5. Plate 23 is supported at a distance above the top of bottom frame members 3 and 4 and of loading floor 5 by means of vertical side plates 24 and 25 (FIG. 4, S and 6) and a front or end plate 26.

The sides of baling chamber 15 are of conventional construction being formed by a series of horizontal steel bars 27 on the front side (FIG. 1) and 28 on the rear side (FIG. 6). These are usually made in the fonn of I-beam sections as illustrated. At their right ends these bars 27 and 28 are pivoted by bolts 29 to short projections welded on the side surface of vertical posts 18. At their right ends the side bars 27 and 28 are individually supported by cuplike members 30 which in turn are supported by coil springs (not shown), one on the interior of each cup member, these springs being fixed on the front side to a vertical channel member 31. The bars 28 for the rear side of the baling chamber are similarly supported.

Thus as a charge of waste material is advanced into the baling chamber 15 by plunger 7 the sides of the mass of waste material are compressed by the springs justmentioned and also cause the side bars 27 and 28 to be forced'outward to some extent, pivoting on the bolts 29 at their front ends. A second upright channel member 32 equipped with a similar set of cuplike members and coil springs may be added on each side of the baling chamber in order to produce greater lateral compression of the waste material. I

In pit 22 there are four upright channel frame members, one at each comer. The two front channel members 33 and 34 are visible in FIG. 1 and the two rear channel members are directly behind them. One of these, 340, may be seen in FIG. 6. Front channel members 33 and 34 are secured at the bottomto a horizontal lengthwise channel member 35, a second such member serving to support the two rear channel members. Front and rear channel members 35 are joined together into a framework by means of steel angle bars 36 shown in FIGS. I and 2.

The U-shaped lifter 37 shown in FIG. 3 is arranged for vertical movement in pit 22. Lifter 37 has a bottom 38 and front and rear sidewalls 39 and 40. To provide the strength necessary to compress the waste material these walls may be made inv a two layer or double construction as shown in FIGS. 2 and 3 where the bottom 38 and each side wall 39 and 40 is constructed of two layers of sheet metal separated and also joined together by a plurality of spaced steel bars 41 which extend lengthwise of the lifter from the left' side thereof to the right. These bars are shown as rectangular bars but if desired bars of other cross section may be used.

In order to operate lifter 37 upwardly and downwardly in pit 22 a lengthwise supporting bar 42 is welded at its upper edge beneath bottom 38 and the ends of such bar project to the left and right respectively and are appropriately connected to endless chains 43 as indicated by dotted lines in FIG. I. The lower end portions of chains 43 engage sprockets which are fixed to a shaft 44. The upper ends of the chains pass over individual sprockets 45 and 46 which rotate freely on short shafts supported on the lower angle members 3 and 4 of the apparatus framework. An electric motor 47 drives shaft 44 and is connected thereto by means of an endless chain 48 and an appropriate speed-reducing unit 49.

In order to form a closed compression chamber within the lifter 37 pit 22 is provided with end walls. Each of these walls at the right and left of the pit comprises a pair of similar steel plates 50 (FIG. 2) which are appropriately fixed in position on the framework of the pit structure and are spaced apart centrally so as to leave a channel 51 for the passage of the end extensions of supporting member 42 for lifter 37. The construction just described is shown in FIG. 2 for the end wall at the right end of pit 22. The wall at the left end is similarly constructed. These two end walls are each provided with an extension plate 52 so as to raise the top edges of the walls to the level of the lower edge of plunger 7 on one side and to the bottom of the entrance to baling chamber 15 on the opposite side.

When lifter 37 is in its lowermost or bottom position the tops of its side walls 39 and 40 are level with the loading floor (FIG. 3) so that it is an easy matter to introduce the waste material into the pit and the U-shaped lifter. When the lifter is somewhat less than full and the plunger 7 has been withdrawn to the right where it enters into a receiving cavity 53 shown in FIG. 4, motor 47 is operated to raise lifter 37. This raises the waste material and as the top edges of the sides 39 and 40 rise above the roof plate 20, as indicated by the dotted lines in FIG. 2, the material is compressed, being confined between the sidewalls of the lifter the end walls 50 of the pit and the extension52 and surface of plunger 7. The material may spill over at the left of the lifter somewhat into the entrance of baling chamber 15. This compression continues until the bottom 38 of the lifter reaches the level of the entrance to the baling chamber and the bottom of plunger 7 which is the limit of the upward movement of the lifter, shown by the dot and dash lines in FIGS. 1 and 2.

Thereupon plunger 7 is operated by hydraulic cylinder 6 and moves the partially compressed material into the end portion of baling chamber 15. Skirt portions 54 which are extensions at the bottom of the sidewalls 39 and 40 of lifter 37 are provided as a safety feature to prevent an operator from placing his toes beneath the bottom of lifter 37.

The lifter is guided in its vertical up and down movement by meansof two pairs of rollers 55 and 56 which are suitably mounted on the framework of the apparatus and engage the sidewalls of the lifter. The lifter 37 is provided with suitable electronic control for its operating motor 47 which includes a manually operated starting button (not shown), and switches 57 and 58 which automatically stop the lifter at its top and bottom positions respectively. Similar control is provided for operating the valve which controls the flow of fluid pressure to and from the hydraulic cylinder 6. This control includes limit switches 59 and 60 which stop the movement of plunger 7 in its movement towards the left and right respectively.

It will be understood that each amount of waste material received in pit 22 is compressed in two stages, an initial partial compression such as effected by the lifter 37, and the complete compression such as produced by plunger 7. it will also be understood that the successive operations of the lifter and plunger are repeated to place sections of compressed waste material in the baling chamber until the baling chamber is filled.

When the baling chamber has been filled as indicated in FIG. 5 plunger 7 is left in position until baling wires 6] are applied. This is done by threading the open ends of the wires through crosswise channels 62 which are provided in plunger 7. With the loop ends of the wires left projecting as shown in FIG. 5 the free ends are carried around the back side of the bale between certain of the bars 28 after which they are swung around the opposite end of the bale and brought back to the loops 63 to which they are secured.
