Description

MOBILE SHREDDING AND BALING -SYSTEM
II TECHNICAL FIELD
This invention pertains to a mobile shredding and baling system, including a a method and apparatus, preferably for use in the handling, shredding and/or s baling of paper and other feed-stock. This invention provides for actual shredding and baling while the vehicle in which the shredder and/or baler is located, is ~~ being driven.
si BACKGROUND OF THE INVENTION
Mobile and other paper shredders have been used for many years to shred to 11 paper and other material. One example of a mobile paper shredder is U.S.
Patent No. 5,542,617, issued to David E. Rajewski on Aul;ust 6, 1996, which is hereby l2 incorporated by reference into this application as though fully set forth herein.
l3 While shredders mounted within an enclosure in a truck have generally m been referred to as mobile shredders because they can be moved from one is location to another, these shredders have heretofore been unable to operate while the vehicle is being driven or moving in traffic for instance.
l, In a typical shredding service, the vehicle operator will drive the vehicle-rs to the site or location where the feedstock _is located, load the feedstock into the input or hopper of the shredding system. The operator then waits until the Io shredding is complete and may intermittently continue to feed the feedstock into the shredder. After shredding is complete, the operator drives the shredder vehicle to the next stop or location.

S:~SH3?t00s~P0l.WPD A?"O.lO.il009N 1 PAT USlrIP-00 While the shredder itself may be efficient or inefficient during its operation when the vehicle is stationary, having a shredder which only operates from a power take-off on the vehicle while the vehicle is stationary is very inefficient.
a Substantial time is lost while the operator waits for the material to be completely shredded before moving to the next site to pick up feedstock.
The material handling aspects of the shreddedl stock also require additional time and management and renders a mobile shredding unit less effective, because after the material is shredded the material must be later handled. The later handling may be dumping it into a storage area or baling it, or dumping it into !o a storage area while it waits to be baled.
It is therefore an object of this invention to provide a more efficient mobile n !z shredding system which provides shredding while the vehicle is being driven. It is a further object of this invention to provide a baling apparatus in combination l3 with a mobile shredding apparatus, although the baling system may but need not m be operable while the vehicle is moving.
!s The features and advantages of this invention, as described in- more detail !6 below, make mobile shredding systems much more efficient.

The terms "a", "an", and "the" as used in the claims herein are used in conformance with long-standing claim drafting practice and not in a limiting way.
l3 Unless specifically set forth herein, the terms "a", "an", and "the" are not limited la to one of such elements, but instead mean "at least one".
Is Figure 1 illustrates a mobile shredding system mounted on and within a truck 2, the truck 2 including a cab portion 2a with an operator compartment l%
therein, and a truck rear enclosure 2b. Figure 1 also illustrates a vehicle or truck Is engine 17.

Figure 1 illustrates a mobile shredding system with an input hopper 3 with ao an input end 3a and an output end 3b. Paper a.nd other feedstock material is fed into the input hopper in any one of a numbeir known of ways, with no one in particular being required to practice this invention. The preferred way to load S:lSH13~0051PDl.GYPD A1'0.lOJI009N 5 P~iT-US1RP-00 the input hopper 3 is utilizing the lifting arm system .disclosed in U.S.
Patent No. 5,542,617, issued August 6, 1996 to David E. Rajewski, which is incorporated 3 I~ herein by reference. The lifter is shown in Figure 1 with a frame 16 in which ~, a feedstock container may be placed and then lifted to place the feedstock in input hopper 3. The preferred lifting system is not described in more detail herein due to the incorporation of U.S. Patent No. 5,542,617 by reference.
The term "input hopper" as used herein is bra~der than its typical meaning, and without limitation, includes hoppers and -any other temporary storage or containment structure for receiving the feedstock material to be shredded. The hopper may then directly or indirectly provide the feedstock material to the feedstock handling system for feeding to the shredder.
r2 Figure 1 illustrates the shredding system 1 with housing 4 and system output 5. Material is placed in the input end 3a of input hopper 3 and is moved to output end 3b of the input hopper for delivery to the shredder. Shredded I ~t material 20 exiting the system output 5 is moved into storage area 6 within the m truck rear enclosure 2b. Shown within rear enclosure 2b is surveillance camera !6 18 monitoring the feed and monitoring the shredding operations, the surveillance camera 18 being operationally connected to a video display in the cab or operator rs -portion 2a of the vehicle.

It will be noted that the storage area may, but need not have a dust control ao system which is comprised of fluid nozzles 8 and fluid conduit 7. The dust z~
control system can be activated to .reduce and control the level of dust in the z?

In order to provide for a mobile shredding system in which the shredder ~, may be operated while the truck or vehicle is being driven, this mobile shredding system includes shredder engine 10 separate from the vehicle or truck engine, hydraulic pump 11, hydraulic lines 12 and 13, and hydraulic drivers 14 and 15 for providing power to the various components of the shredding system, as will be described more fully below. The shredder engine 10 would include all the ancillary items necessary to operate it, such as a gas tank, an ignition system, and o the like.
It should be noted that while the shredding system in Figure 1 is shown with an independent shredder engine 10, an independent engine is not required to l2 practice embodiments of this invention, but instead other ways may be employed, such as power take-off mechanisms which are readily known in the art.
i-t The shredder engine 10 may be a diesel or a gas engine, as no one ~s particular type is required to practice this invention. The hydraulic-components such as the hydraulic pump 11, hydraulic lines 12 & 13, and the hydraulic drives 14 and 15, are also well known in the art. Alternatively, an engine could drive is a generator which would provide electricity to individual motors or drives for the various applications required by this invention, as described more fully below.
zo Figure 1 further illustrates pressure sensor 400 in hydraulic line 12 which measures the hydraulic pressure to the hydraulic drive 15, and hydraulic valve ,~
in hydraulic line 13 (which drives the conveyors and the feed drum. The S:ISN21S0051P0l.WPD A?'O.t0.iH009N 7 PAT USIAP-00 I combination of the pressure sensor 400 and the r~ydraulic valve 401 act as a governing system such that when high pressures are sensed in the shredder, the pressure sensor 400 detects the higher pressure in the hydraulic line 12 and a signals to the hydraulic valve 401 to stop the flow of hydraulic fluid to hydraulic drive 14. Stopping the flow of hydraulic fluid to hydraulic drive 14 stops the first conveyor, the second conveyor and the feed drum, thereby causing the feeding to the shredder to be stopped when a pressure over pre-determined pressure is reached. This may occur if too much feedstock or excessively large or dense pieces of feedstock are moving through the feeder. This results in fewer to equipment overloads, jams and breakdowns.
II The preferred way of configuring the mobile; shredder is with a feedstock material handling system an embodiment of which is shown more fully in Figures IZ
2 - 6. However, there are other less efficient embodiments to which this mobility invention applies which are currently known in the art, an alternative embodiment m of which is shown in Figures 10 & 11.

Figure 2 shows a rear elevation view of on.e embodiment of a shredding system 1 as contemplated by this invention, and also as illustrated ~in Figure 1, I%
illustrating the input hopper 3, the input end 3a of :input hopper 3, the output end Is 3b of input hopper 3, and first conveyor 35 with first conveyor surface 37 moving in conveyor direction 36. First conveyor 35 is on conveyor drivers or supports ZO
38 and 39 which are rotated about their axes 52.
Zr Figure 2 further illustrates second conveyor 30, second conveyor surface 3I
zz moving in conveyor direction 32 (upwardly in this illustration), supported by S:1SN11~OOSIPOLWPD A:"O~Oit009N g PAT UStAP-00 1 conveyor supports 33 and 34 and rotated by axes 51. It will be appreciated by those skilled in the art that while the second conveyor 30 is shown vertically 3 oriented, there are other angles of greater or less than ninety degrees to the first ~, conveyor 35 at which the second conveyor 30 may be oriented to accomplish the feed control function it serves, all within the contemplation of this invention and depending on various factors such as the desired feed rate, the feed material, and others.
It will be noted by those of ordinary skill in the art that other types of conveyors may be used as the second conveyor, with the key being a moving ro surface spaced apart from the first conveyor and which may move excess 11 feedstock from around the feed aperture. An example of a different conveyor of the excess feedstock at the feed aperture is a Feeder Beater Drum as produced and available from Cash Hardware Company, possibly with fingers, shields, heads and sprocket. These may be similar to the feeder drum, only with the f nger and 1-i shield mechanism preferably included.
Is Second conveyor 30 preferably has nubs 29 on the surface to assist in the gripping and moving of the feedstock J
The feedstock 21 being fed into the hopper 3 is fed or output to first l8 ' conveyor 35 where it is moved in conveyor direction 36 toward the feed aperture 40. In many situations there will be more material to shred than can easily or ao efficiently be passed through feed aperture 40 and the excess feedstock not Il passing through feed aperture 40 will come into contact with second conveyor surface 31 of second conveyor 30 and be pushed or pulled upwardly in conveyor S:ISN=?10051P0l.WPD A2'0-105~009N 9 P.IT=USIAP-OD

r direction 32. This has the effect of lifting the feedstock. material away from feed 2 aperture 40, and prevents jam through feed aperture 40, and further allows for more efficient and effective metering or feeding of f~edstock through feed aperture a 40. The feedstock 21 coming in contact with second conveyor surface 31 is lifted and eventually falls back toward feed aperture 40 and will eventually be fed through it at a time when it can more readily be received through feed aperture 40.
Feedstock passing through feed aperture 40 then encounters feed drum 41 rotating on shaft or feed drum axis 50. It is preferred but not required that feed o drum 41 include feed projections 42 which assist in grabbing or engaging feedstock passing through to urge it to continue to flow toward shredder 43.
Feed drum 41 is rotated by hydraulic drive 14 in t:he manner shown in Figure 4, and more fully described below. A specific type or kind of shredder 43 is not required to practice this invention, however, in i:he high speed, high volume ,~
application of this invention, a hammermill type ma.y be preferred, whereas in the is lower volume applications, a shear type of shredder may be preferred. Figure 2 l6 illustrates a shear type of shredder.
As is better illustrated in later figures and more fully described below, feed rs drum 41 is bias mounted on a pivot arm such that it may move in the direction !9 indicated by direction arrow 70, the feed drum 41 being biased in the downward zo direction, as is described more fully below. Allowing movement of feed drum 2l 41 allows for larger pieces of feedstock to pass through to the shredders without S:ISH221005tPOLWPD A2-O.fOSf009N 1~ PATUSIAP-00 clogging or jammingthe system in around drum 41 and feed aperture and feed 40, while continuingto feed or providefeedstockto shredder 43.
21 the The shredder 43 may be any one of a number of different types of a shredders within the contemplation of this invention, as no one in particular is required to practice this invention.
Figure 2 further illustrates shredder input 43a, shredder output 43b, shredder screen 45 around shredder 43 and system output 5, which is a discharge hopper.
Figure 2 still further shows three augers 62 which act as compactors and compact 9 the shredded material as it is received from the shredder output 43b and before to it is fed to the system output 5. Figure 3 more fully illustrates a side view of rl one of the three preferred augers. There is typically a large mass of shredded material filling the area around augers 62, which allows for efficient compacting of the shredded material exiting the shredder 43.
l3 ' Figure 2 also illustrates how the feed drum 41, which rotates clockwise, m and the first conveyor 37, which rotates counter-clockwise, provide the feedstock IS
to the shredder in a more usable way since the combination tend to . feed wider or longer pieces of feedstock lengthwise into the shredder 43 for shredding.
Under prior systems, wider or longer pieces of feedstock may be fed onto the J8 _ shredder 43 such that the longest or widest section is oriented more.
horizontally, l9 sometimes causing the feedstock pieces to dance or remain on top of the shredder zo 43 without being drawn through and shredded. This more efficient feeding and orienting o.f the feedstock contributes to the efficiency and effectiveness of the feed system.

The shredder screen output 61 provides or delivers material to augers 62, which are disposed to receive the shredded material. Augers 62 are rotated by auger shafts 62a and move the shredded material in siirection 63 and causes it to further move in direction 70. The material exiting the shredder typically includes a substantial amount of air and is very fluffy. Augers 62 serve to compact or ro pre-pack the shredded material before it is dropped into the area of the ram to II be pushed through system output 5, i.e. to condense it or reduce the quantity of air in the volume of shredded material.
l2 This pre-packing or compaction combined with the action of the ram 66 - allows for more material to be moved through and handled by the shredding m system. Hydraulic cylinder 64 pushes hydraulic; cylinder shaft 65 which is l, attached to ram 66 to move material received from auger 62 out system output l6 ' 5. Hydraulic cylinder 64 is mounted to housing 4 and provides the movement I-indicated by the arrows on a continuous basis during operation.

The shredded material received from augers fit is received in discharge area l9 90, and ram 66 pushes the shredded material through discharge area outlet 90a.
As more material passes through and is pushed through discharge area outlet 90a, 2l it pushes the material through system output 5 an<i into the storage area 6 with the truck enclosure (as shown more fully in Figure 1).

The two conveyors deliver balestock through feed aperture 140, and at the l6 exit end of feed aperture 140 is feed drum 141, which provides or delivers I"
l8 balestock material to augers 162, which are disposed to receive the balestock material. Augers 162 are rotated by auger shafts 162a and move the balestock l9 material in direction 163 and causes it to further move in direction .170. The ZO
material typically includes a substantial amount of air and is very fluffy.
Augers 2l 12 serve to compact or pre-pack therbalestock material before it is dropped into the discharge area of the ram 166 to be pushed through system output 105, i.e.

S: iSH1?t005tPOl. WPD AZ'O.IOSI009N 14 PAT US4iP-00 r to condense it or reduce the quantity of air in the volume of balestock material.
2 This pre-packing or compaction combined with the action of the ram 166 allows for more material to be moved through ;end handled by the material handling system for balers 100. Hydraulic cylinder 164 pushes hydraulic cylinder shaft 165 which is attached to ram 166 to move balestock material received from auger 162 and move it out system output 105. Hydraulic cylinder 164 is mounted to housing 104 and provides the movement indicated by the arrows on a continuous basis during operation.
The balestock material received from augers 162 is received in discharge to ~'ea i 90, and ram 166 pushes the balestock material through discharge area outlet II 190a. As more material passes through and is pushed through discharge area outlet 190a, it pushes the balestock through system output 1055 and into the Iz baler input 119a of the baler 119.

The system output chute I0~ can place or deliver balestock material into m baler 119 in any one of a number of different ways but all within the h contemplation of this invention, such as from the side as shown, or from the top.

S:ISH1110051POLfYPD A1-Od051009N 19 PAT USIAP-00 Feed drum 341 is rotated by hydraulic drive 314 in the manner shown in Figure 11, and more fully described below.
3 ~~ As is better illustrated in Later figures and me>re fully described below, feed drum 341 is bias mounted on a pivot arm such that it may move in the direction indicated by direction arrow 370, the feed drum 341 being biased in the downward direction, as is described more fully below. Allowing movement of feed drum 341 allows for larger pieces of feedstock to pass through to the 8 shredders without clogging or jamming the system in and around feed drum 341 and feed aperture 340, while continuing to feed or provide feedstock 321 to the o shredder 343.
ll The shredder 343 may be any one of a :number of different types of shredders within the contemplation of this invention, as no one in particular is l2 required to practice this invention.
l3 Figure 10 further illustrates shredder input 343a, shredder output 343b, 1.1 shredder screen 345 around shredder 343 and sy:>tem output 305, which is a IS
discharge hopper.

Figure 11 is a side elevation view of the shredder system 301, illustrating i, input hopper 303 with input end 303a, housing 304, shredder 343, first conveyor 335, shredder screen 345, shredder axis or shaft 353, and shredder screen apertures l9 2o i 360.
The shredder screen output 361 provides or delivers material to discharge area 390 with discharge area output 390a. Hydraulic cylinder 364 pushes zz hydraulic cylinder shaft 365 which is attached to ram 366 to move material S:ISN22~OOSIPOLWPO .12.'O.fOSl0o9N 2~ P~1T USIAP-00 received from shredder 343 out system output 305. Hydraulic cylinder 364 is mounted to housing 304 and provides the movement indicated by the arrows on 3 a continuous basis during operation.
., The shredded material received from shredder 343 is received in discharge area 390, and ram 366 pushes the shredded material. through discharge area outlet 390a. As more material passes through and is pushed through discharge area ~~ outlet 390a, it pushes the material through system output 305 and into the baler input 221 a (shown in Figure 9).
The system output chute 305 can place or deliver shredded material to Io baler input 221 a in one of a number of different ways but all within the II contemplation of this invention, such as from the side or from the top.
In compliance with the statute, the invention has been described in language more or less specific as to structural and methodical features. It is to be . understood, however, that the invention is not limited to the specific features I~
shown and described, since the means herein disclosed comprise preferred forms IS
of putting the invention into effect. The invention. is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims I;
appropriately interpreted in accordance with the do<;trine of equivalents.
