- the invention relates to the field of baling loose, compressible medium such as paper, cardboard and the like wherein compression is produced in a horizontally disposed compression chamber by means of a hydraulic ram, and the com pressed medium is transferred from the compression ram for strapping purposes.
- Baling apparatus for scrap materials such as paper, cardboard and the like which is of the so-called high capacity" type capable of producing relatively large, high-density bales, and baling a large tonnage in a given time period are usually of two types, vertical or horizontal.
- Vertical baling equipment employs a compression chamber which is vertically disposed, and the horizontal type balers use a compression chamber horizontally disposed.
- balers receive the material to be baled within the compression chamber and a ram, either hydraulic or mechanical, is moved vertically, usually upwardly, to compress the material at an end region of the chamber. After several compression strokes, with additional material being introduced into the chamber between strokes, a bale is formed in the end portion of the chamber and strapping of the bale occurs while it is located within the compression chamber. This arrangement has the disadvantage of rendering the baler inactive while strapping of the bale occurs. Additionally, vertical chamber baling devices have relatively small compression chamber loading openings due to the constructional limitations of this type of baler.
- Horizontally disposed balers such as represented in US. Pat. No. 3,212,434, consist of an elongated, open end, horizontal chamber into which the material to be compressed is introduced.
- Ram or compression means periodically reciprocate within the chamber to force the medium being compressed into and through the compression chamber.
- the compression chamber is so shaped that the resistance of movement of the medium through the chamber produces a sufficient compression and density.
- a predetermined portion of the compressed material is strapped as it periodically moves through a final stage of the compression chamber.
- dividers are periodically inserted into the medium being compressed wherein the bale straps may be inserted through the compressed material and produce the strapping of the bale.
- the density of the material being compressed fluctuates with the movement of the ram or plunger and control of the density, and size of the bale is difiicult to regulate.
- baling apparatus of the vertical and horizontal type usually requires that paper and cardboard be shredded or hogged prior to being introduced into the compression chamber.
- Such shredding is primarily necessitated by the inability of the loading openings of conventional baling apparatus to accommodate large boxes and paper sheets, and it is usually necessary to employ shredding means with the balers in order to pennit the most efficient and effective use of the balers.
- the invention pertains to a horizontal baling apparatus of unique design which is capable of baling large tonnage in a relatively short time interval with a minimum of labor and supervision.
- the baler constructed in accord with the invention is capable of forming and compressing a bale, while strapping of the previously formed bale is occuring.
- baler constructed in accord with the invention result from the horizontal disposition of a closed end compression chamber and the utilization of a transversely disposed ram for transferring the compressed medium from the compression chamber to a strapping chamber.
- the loading opening is of sufficient size to eliminate the requirement for previously shredding or hogging the material to be compressed, and thus, an expensive and time-consuming operation which was previously necessary with conventional balers is eliminated.
- the baler of the invention is able to employ a loading opening which is of a width equal to the compression chamber width, and a length substantially equal to the length of travel of the compression ram or plunger.
- a traverse ram or plunger is actuated which moves at right angles to the compression ram and transfers the compressed material from the compression chamber directly into a strapping chamber. Strapping occurs within the compression chamber, and as the compressed material is static during strapping, automatic strapping apparatus may be used, if desired. By utilizing separate compression and strapping chambers interruption of the compression operation is minimized, tending to substantially increase the capacity of the baler over more conventional constructions.
- Balers constructed in accord with the invention are capable of producing at least twice the baling capacity of balers currently in use while only requiring one-half of the number of normal attendants.
- the baler may be operated from a central control center wherein effective supervision is produced and the complete machine is exposed for convenient maintenance and servicing.
- Loading of a horizontal baler in accord with the invention is simplified due to the size of the loading opening and loading may be readily accomplished by means of a conveyor or other mechanical apparatus.
- baler of the invention the compressed bale is transferred from the compression chamber in a direction parallel to the bale layers and confined in the strapping chamber in a stationary manner.
- the baler apparatus in accord with the invention is capable of producing very high density bales, and maintaining the density during strapping.
- each bale constructed formed by the apparatus of the invention is of a uniform size and configuration, which simplifies handling and storage.

Likewise, the strapping chamber is provided with lower strap guides 126 disposed between the bottom rollers 1 16.
- the outlet 114 of the strapping chamber extends away from the baler apparatus, and a bale-receiving dock, platform or conveyor will be disposed adjacent the strapping chamber outlet to receive the strapped bale upon the bale being ejected from the strapping chamber.
- baler in accord with the invention is semiautomatic and the control means are illustrated in FIGS. 9 and 10.
- two electric motors 64 are employed which are preferably each of 75 H.P., and each are operatively connected with a hydraulic pump 128 and a hydraulic pump 130.
- the pumps 128 are of a high capacity, low pressure type capable of pumping 75 gallons per minute at pressures approaching 1,500 pounds per square inch.
- the pumps 130 are of low capacity, high pressure capable of pumping 50 gallons per minute at pressures exceeding 2,500 pounds per square inch.
- the output of the pumps 128 and 130 is normally supplied to the primary pressurized conduit 132. However, when the pressure within the conduit 132 exceeds 1,500 pounds per square inch the control conduit 134 actuates bypass valve 136 to bypass the output of the low-pressure pumps 128 into the hydraulic fluid reservoir.
- Control of the compression ram 26 is accomplished by a hydraulically operated valve 138 of the Olmstead type.
- the portion 140 of the control valve 138 is associated with the end of the ram producing piston extension, and the valve portion 142 is associated with the pistonrod end of the ram.
- Small hydraulic cylinders 144 control the operation of the valve 138, and the control cylinders 144 are operated by the primary pressure on valves 143 and 145 controlled by the solenoids 146 and 148, respectively.
- Pressure switches 154 and 156 communicate with the extension end of the ram 26 to sense the pressure within the ram during compression of the medium being baled.
- Switch 154 as will be later described, is used to sense the pressure during compression and regulate the regeneration operation.
- Pressure switch 156 is employed to sense the occurrence of the desired compression pressure.
- Operation of the traverse ram 86 is controlled by the hydraulically actuated valve 158, which is shifted between its various positions by control cylinders 160.
- Control cylinders 160 are operated by the valve 162 controlled by solenoids 164 and 166.
- control of the cover ram is directly accomplished through valve 168 which is shifted between its operative positions by solenoids 170 and 172.

- the cylinder 182 is energized through the valve 186 actuated by solenoid 188, and the control cylinder 184 is operated by the primary pressure source of the system.
- a pressure relief valve 190 which opens at 2,500 pounds per square inch communicates with the pressure conduit 132 and the primary pressure also communicates with a valve 192 operated by solenoid 194.
- the valve 192 communicates with a pressure relief valve 196 which opens at 2,000 pounds per square inch to return the fluid to the reservoir.
- the flow of fluid through the pressure relief valve 196 occurs as long as the valve 192 is in the open position illustrated, and the position illustrated is the normal operating position of the system.
- Solenoid 188 must be energized at all times when pressure is required in the system, otherwise, the valve 186 will shift to a position causing the valve to exhaust directly to the reservoir. Energizing of the solenoid 188 causes the fluid to flow through the valve 192 and the pressure relief valve 196 to maintain 2,000 pounds per square inch pressure in the system. Should pressures higher than 2,000 pounds per square inch be momentarily desired to properly orient the rams, for instance, if the operator permitted more material to be placed in the compression chamber 24 than intended, higher pressure is produced by energizing solenoid 194 to prevent flow through valve 192 and render pressure relief valve operative to control the pressurized system.

- the gate ram 106 includes in its circuit the stop switch 270 and start switches 272 and 274, bridged by normally open relay contacts 232' and 234', respectively.
- Solenoid 176 and relay 232 are in series with limit switch 276, and normally closed relay contacts 234".
- Solenoid 178, and relay 234 are in series with limit switch 278 and normally closed relay contacts 232".

- the solenoid 194 is energized by the manually operated switch 282.
- the switch 282 is of the type which must be manually depressed as the requirement for the higher pressures resulting from energization of the solenoid 194 will only be momentary.
- the limit switches described above are mounted upon the baler structure for actuation by the appropriate pistons, plungers, gates, etc. and the approximate location of the switches is diagrammatically indicated in FIGS. 1 and 2.
- the distance separating the compression chamber sidewalls 16 is substantially 60 inches, while the longitudinal length of the compression chamber loading opening 44 is substantially 120 inches.
- the unusually large size of the access opening permits bulky boxes, cartons and other scrap paper articles to be introduced into the compression chamber without the need for shredding or hogging the scrap articles.
- the vertical dimension of the compression chamber is substantially 36 inches, and the aforementioned dimensions permit the compression chamber to be quickly loaded by means of a conveyor or other mechanical material-handling apparatus.
- baler As the baler is of the horizontal type, it is possible to locate the baler below floor level wherein material to be baled may be directly pushed into the compression chamber by a bulldozer or the like.
- the baler apparatus may be mountedupon a ground level supporting surface, rather than being located within a pit, and in such instance a loading platform would probably be located adjacent the compression chamber opening on a horizontal level therewith to aid in introduction of the material into the compression chamber.
- the operator located at the console 60 will energize the primary motor switches 206, if the pump motors 64 have not already been started.
- the switch 262 is closed to energize solenoid 170 to shift valve 168 to extend the cover rim and close opening 44.
- the operator then closes cycle switch 212 which energizes solenoids 146 and 148 which produces an actuation of the valve 138 permitting pressurized fluid to be introduced into the left, or extension end of the compression ram 26, HG. 9, to begin extending the piston 28 and moving the compression ram wall or plunger 34 toward the end wall '70.
- valve portion 142 As energized by valve 145, is positioned such that the fluid being exhausted from the pistonrod side of the compression ram is introduced into the pressurized circuit, and the supply conduit 132 and extension side of the ram 26.
- This utilization of the hydraulic fluid exhausted from the compression ram constitutes a regeneration cycle permitting a maximum amount of pressurized fluid to be introduced into the compression ram and produce an initial rapid movement of the compression ram.
- the pressurized fluid conduit 132 will be receiving fluid from both pumps 128 and both pumps 130, in that the pressure within the system will be less than 1,500 pounds per square inch.
- the resistance to movement of the compression ram becomes great enough to cause the fluid pressure within the supply conduit to reach approximately 800 pounds per square inch, such a condition is sensed by the pressure switch 154.
- Pressure switch 154 then opens and deenergizes solenoid 148 which shifts valve portion 142 from the regeneration position, to the exhaust-to-reservoir position shown in FIG. 9.
- the compression ram piston will continue to compress the material within the compression chamber, and upon the pressure within the supply conduit I32 reaching 1,500 pounds per square inch, the bypass valve 136 will open to bypass the output of the low-pressure, high-volume pumps 128 into the fluid reservoir.
- the bypass valve 136 will open to bypass the output of the low-pressure, high-volume pumps 128 into the fluid reservoir.
- the purpose for removing pumps 128 from the operative system at 1,500 lbs. per/sq. in. is to permit the desired fluid pressures to be developed with electric motors of approximately 75 HP. each.
- Completion of the first stroke of the compression ram is sensed by the limit switch 238 located adjacent the entrance to compression chamber portion 68. Closing the limit switch 238 will energize relay 220 and thereby energize solenoid 148 and deenergize solenoid 146. This operation permits pressurized fluid to be introduced into the pistonrod end of the compression ram and retract the ram. The compressed material will stay within the compression chamber portion 68 when the compression ram is retracted.
- Retraction of the compression ram 26 is sensed by the limit switch 214 which opens to hold the retracted ram on manual standby by deenergizing solenoid 148. After the cover 46 is retracted additional material to be compressed is introduced into the compression chamber through opening 44 and the above cycle is repeated. Several loadings, usually three or four, of the compression chamber will be necessary before the desired density bale has been achieved. Of course, the number of cycles of the compression ram will be determined by the amount of material introduced into the compression chamber with each loading, and the nature of the material being compressed.
- the limit switch 250 is preferably of the magnetic detector type, and a magnet located upon the compression ram structure energizes the limit switch 250 when the compression ram wall 34 is in the position shown in FIG. 8. Closing of the limit switch 250 will prepare the traverse ram circuit for energization.
- Limit switch 256 is located at the entrance 112 of the strapping chamber and will sense the full extension of the traverse ram 86. The limit switch 256 will automatically return both the compression ram, through contacts 256', and the traverse ram to retracted positions as the limit switch energizes the solenoids 148 and 164 2 or 3 seconds after the traverse ram has penetrated the strapping chamber inlet. Limit switch 258 will sense the retracted position of the traverse ram and hold the traverse ram on manual standby," and limit switch 214 will sense the retracted condition of the compression ram, and likewise, maintain the compression ram in a manual standby" condition.
- the operator closes switch 272 to actuate solenoid 176 and relay 232 to extend the gate ram 106 and locate the gate within the compression chamber discharge opening 100 and extend rams 72 to move wall 70 toward head 34. Also, the operator will close switch 264 and energize solenoid 172 to retract the cover ram 52 and provide access to the compression chamber portion 42 for loading with new material to be compressed.
- Compression of the material has usually taken place through several cycles of the compression ram.
- the material within the compression chamber portion 68 prior to being transferred to the strapping chamber 102, will exist in layers perpendicularly disposed to the axis of the compression ram.
- the tendency for the compressed material will be to expand against the side rollers 118.
- the side rollers 118 will not pennit expansion, the dimensions of the compressed material will be closely maintained.
- Strapping of the compressed material within the strapping chamber 102 is quickly accomplished by inserting the baling straps 1 into the slots 120 disposed between the rollers 116 and 118.
- the presence of the band strap guides 122, 124, and 126, facilitates the placing of the banding straps about the bale. and either an automatic or a manual strapping apparatus may be employed to tension and clamp the straps 284.
- the bale is strapped in the direction as to confine the bale against expansion due to the layering" of the compressed material.
- the baling straps upon the bale being removed from the strapping chamber 102, no significant expansion of the bale will be permitted by the baling straps.
- the baler in accord with the invention permits simultaneous bale compression and strapping.
- the bale previously inserted into thev strapping chamber will usually be completely strapped by the time that the subsequently compressed material is ready to be transferred into the strapping chamber.
- the gate 104 is opened and the traverse ram 86 actuated to introduce the compressed material into the strapping chamber. This operation will push the strapped bale from the strapping chamber 102 through the strapping chamber outlet 114 and onto a conveyor or platform.
- the traverse ram 86 is retracted, the gate 104 is reinserted into the discharge opening 100 and the strapping and compression cycle repeated.
- bale size 60X36 48 inches is produced which will weigh between 1,500 pounds and 1,700 pounds.
- three strokes of the compression ram will be used when baling mixed corrugated boxes, paper, etc., and the designed cycle time for the compression ram is approximately 25 seconds.
- the cycle time for the traverse ram is approximately 15 seconds, and the total time to form a complete bale is in the neighborhood of 90 seconds under optimum conditions.
- Baling apparatus of the disclosed type can be operated efficiently with three attendants, one attendant operating the control console, another attendant supervising the loading of the material, and the third attendant supervising or producing the strapping of the bale.
- the baling apparatus is capable of operating at one-half speed should one of the motors or pumps require maintenance.
- the movable wall 70 provides a dual function in the operation of the apparatus. its basic function is to reduce the power requirement of traverse ram 86 when transferring the bale from the compression chamber to the strapping chamber. By retracting wall 70 prior to extending ram 86 the friction between the bale and wall 70 will be reduced as the bale is transferred. Secondly, as previously mentioned, if the compression ram 26 is unable to fully extend during the last compression stroke the retraction of wall 70 will permit this operation and thereby assure that head 34 is properly oriented to opening during transfer of the bale.
- a horizontal paper baler apparatus comprising, in combination, a frame, a substantially horizontally disposed, elongated, compression chamber defined on said frame having a substantially horizontal bottom plate, sidewalls, an upper portion and first and second end regions, a loading opening defined in said chamber upper portion at said first end region, a first ram having a head mounted within said chamber longitudinally movable therein between said first and second end regions, a second ram having a head communicating with said chamber second end region transversely movable with respect to the length of said chamber across said bottom plate at said second end region, a discharge opening defined in said chamber second end region in opposed relation to said second ram head, bale-strapping means disposed adjacent said discharge opening for strapping compressed paper moved from said second end region by said second ram head through said discharge opening and control means controlling operation of said rams.
- bale-strapping means includes a bale-supporting surface in substantial alignment with said bottom plate for supporting bales ejected from said compression chamber second end region by said second ram head.
- a horizontal baler apparatus comprising, in combination, a frame, a substantially horizontally disposed unitary, elongated, compression chamber defined in said frame having a bottom, sidewalls, an upper portion and first and second end portions, said bottom being common to said first and second end portions, a loading opening defined in said chamber upper portion, a first ram mounted within said chamber longitudinally movable therein between said first and second end portions thereof, a second ram communicating with said chamber second end portion transversely related to the length of said chamber and having an operative path of movement transversely extending across said second end portion, a discharge opening defined in said chamber second end portion in opposed relation to said second ram, closure means selectively sealing and opening said discharge opening, said second ram and closure means defining a portion of said compression chamber second end portion, and control means controlling operation of said rams and said closure means.
- a strapping chamber having an inlet and an outlet, said strapping chamber being disposed adjacent said compression chamber second end portion and said strapping chamber inlet aligning with and communicating with said compression chamber discharge opening whereby bales formed in said compression chamber second end portion by said first ram are transferred into said strapping chamber by said second ram.
- first and second rams comprise hydraulic expansible motors, said first ram having a direction of movement parallel to the length of said compression chamber and said second ram having a direction of movement substantially perpendicular to said first ram direction of movement and an extent of movement greater than the width of said compression chamber as defined by said sidewalls.
- a horizontal baler apparatus comprising, in combination,
- a substantially horizontally disposed frame a bottom plate and spaced, parallel sidewalls mounted on said frame, said sidewalls having first and second ends, said walls defining a first open top compression chamber receiving portion, a movable wall mounted on said frame having a first position in substantial alignment with one of said sidewalls second ends to define an extension thereof and having a vertical dimension substantially equal to that of said one sidewall, a gate movably mounted on said frame having a closed position in substantial alignment with the other of said sidewalls second end to define an extension thereof and located in opposed relation to said movable wall and having a vertical dimension substantially equal to that of said other sidewall, a top wall extending over said bottom plate above said movable wall and said gate and an end wall extending from said bottom plate to said top wall, said bottom plate and side, top, end and movable walls and said gate adapted to define a second compression chamber portion, a compression plunger wall movably mounted on said frame within said first compression chamber portion in opposed relation to said end wall and movable toward and away
- a strapping chamber having an inlet and an outlet, said strapping chamber positioned adjacent said compression chamber outlet opening, said strapping chamber inlet communicating with said outlet opening whereby a bale compressed within said second compression chamber portion is transferred to said strapping chamber upon said movable wall moving through said outlet opening.
- Apparatus for baling paper products which tend to form layers when compressed comprising, in combination, a frame, a horizontal compression chamber defined on said frame adapted to receive uncompressed paper products, horizontal movable compression means within said chamber compressing paper products therein wherein the compressed paper products are disposed in layers substantially perpendicularly disposed to the direction of movement of said compression means, a discharge opening defined in said compression chamber substantially parallel to the direction of movement of said compression means, transfer means defined on said frame in opposed relation to said discharge opening for transferring the compressed paper products while under compression from said compression chamber through said opening in a direction substantially parallel to said layers, and balestrapping means adjacent said compression chamber opening and located exteriorly of said compression chamber for strapping the compressed bale in a direction transverse to said layers.
- Apparatus for baling paper products as in claim 9 including means for reducing the degree of compression of said layered compressed paper products in the direction of said movable compression means while being transferred by said transfer means.
