A. Laverne, Paris, France, assignor to Societe Industrielie de Transports Automobile, S.i.T.A. (Socit anonyrne), Paris, France, a company of France Filed Nov. 29, 1963, Ser. No. 326,705 Claims priority, application France, Dec. 5, 1962, 917,624 13 Claims. (Cl. 214-83.3)
  • This invention is directed particularly to refuse-collector vehicles although it more broadly relates to apparatus for handling solid materials of any nature in more or less particulate form.
  • a type of municipal garbage truck or refuse collector vehicle in current use is provided at its rear with a container or bin having a generally semi-circular wall with its open diameter directed forwardly towards the body of the vehicle.
  • a vane-like member is mounted for reciprocatory rotation on a shaft upstanding from the bin, somewhat after the fashion of a ships rudder. Garbage dumped into the bin, as from dustbins or the like, is alternately swept up by the vane member on its alternate strokes rightward and leftward and discharged from the bin into the body of the vehicle.
  • the bin is arranged so that its base slopes upward into the vehicle body.
  • Objects of this invention include the provision of improved mechanism for operating a reciprocating chargingvane member of the kind referred to.
  • this mechanism comprises a pair of fluid ram actuators and a linkage of such inherent geometry as to impart varying torque and varying velocity to the vane in the different stages of its reciprocation as required for maximum sweeping efiiciency; specifically to impart relatively high velocity and low torque during the initial receding phase of the sweep and high torque with lower velocity during the active forward sweep.
  • a consequent object is to permit the use of an oil pump of constant delivery and moderate power rating for powering the vane, which pump can be easily driven from the vehicle engine in idling condition, without requiring an auxiliary motor, and without requiring the vehicle engine to deliver a relatively high output torque when idling in the stationary condition of the vehicle.
  • This in turn has an important advantage in that it makes it possible to provide the vehicular power system with automatic clutch arrangements of the hydraulic, centrifugal, or magneticpower types, this being an extremely desirable feature in the case of municipal refuse collectors subject to repeated starts and stops, and a feature difiicult or impossible to realize where the vehicle engine is required to deliver considerable power while the vehicle is at a standstill for actuating the refuse-charging vane mechanism.
  • Additional objects of the invention relate to improved constructional features of the refuse-dumping and charging structures provided at the rear of a refuse-collector van.
  • the charging-vane-reciproeating mechanism comprises two fluid rams or actuators each having one end pivoted to a fixed structure and its other end pivoted to a respective crank arm projecting from the vane-mounting shaft.
  • the relative angular setting between the crank arms and the vane, and the positions of the fixed pivots for the outer ends of the actuators, are so predetermined in relation to one another that each actuator extends substantially at right angles to the associated crank arm as the vane sweeps through a corresponding one of its forwardly directed terminal stroke portions during which the material is being compacted.
  • maximum torque is applied to the vane during the terminal stage of each stroke.
  • each actuator assists the other in crossing its dead-center position.
  • advantage is taken of the differential effective cross sections of each of the actuators on opposite sides of the piston therein, due to the presence of the piston rod on one side, for increasing the velocity of rotation of the vane during its receding or relatively idle arc.
  • FIG. 1 is a side-elevational view of the rear part of a refuse-collector truck provided with refuse-charging structure according to the invention
  • FIG. 2 is a section on line 11-11 of FIG. 1;
  • FIG. 3 is a rear view according to the arrows III-III of FIG. 1;
  • FIG. 4 is an overhead view in the direction of the arrow IV of FIG. 1, with the cover of the mechanism casing removed, showing one embodiment of two-ram actuator mechanism according to the invention;
  • FIG. 4a is a view similar to FIG. 4 but on an enlarged scale to show certain additional details of the mechanism
  • FIG. 5 is a diagram of one form of hydraulic control system usable with an improved two-ram mechanism according to the invention.
  • FIGS. 6 and 7 are bottom plan views respectively showing two modified forms of the mechanism.
  • FIG. 8 illustrates in plan yet another modification of the dual-ram mechanism of the invention.
  • FIG. 1 the rear part of the frame of a refuse van which is not completely shown since its general construction may be conventional.
  • the body of the van defines a refuse-containing chamber 1.
  • the rear opening of the chamber 1 is provided with a door frame or panel 2 swingable about a horizontal axis on a shaft 3 extending across the top of the van structure, this door frame including side members 13a, 13b as well as bottom and top members 13c, 13d and an intermediate brace 132.
  • the door panel 2 In the normal or charging position, the door panel 2 is closed with side members 13a, 13b resting on complementary members of the vehicle frame, as shown in FIG. 1, the side members being held in such position by means of retainer hook members 4 at the lower part of the frame.
  • the panel 2 is formed in its lower part with two apertures separated by a sturdy vertical partition 14, to provide entrances for the refuse in the closed position of the panel 2 as will presently appear.
  • the entire refusecharging system to be described below is supported from the outer or rear side of panel 2 so as to be in operative position when the panel is closed.
  • the panel 2 together with the refuse-charging mechanism supported from it is swung bodily upward about the pivot shaft 3, thereby fully uncovering the rear aperture of the collector chamber 1, and the van is then tilted rearwardly about its rear axle in the conventional manner to dump the contents of the van chamber.
  • a charging bin is secured to and projects rearward from the lower part of the side members or uprights 13a, 13b, the bin 5 being of generally semi-cylindrical shape (thus semi-circular as seen from above) and inclined at a rearward angle, with a frustoconical base 5a as will be clear from FIG. 1.
  • a strong steel-strip hooping tightly surrounds the casing 10 and bin 5, see especially FIG. 3.
  • a cross member 12 interconnecting the lateral uprights 13a, 13b extends across an upper diameter of bin 5 and carries a third bearing 11 for journaling an intermediate point of shaft 7.
  • a heavy vane member 6 Secured to the lower part of shaft 7 within the bin 5 is a heavy vane member 6 which, on reciprocating rotation of the shaft 7, sweeps over a semi-circular path between end positions 6 6 in the bin as indicated in FIG. 2, thereby to sweep up refuse in the bin and propel it upwards alternately through one and the other of the two entrance passages 13, 13" and into the collector chamber 1.
  • Diagonal braces 16 interconnect the central part of cross member 12, carrying bearing 11, with the sides of casing 10.
  • the cross member 12 and partition 14 serve to impart to each of the refuse passages the requisite strength against the outwardly directed thrust of the pile of refuse being pushed therethrough, while the intermediate bearing 11 carried by cross member 12 provided a strong interconnection between the shaft 7 and the member 12 and therethrough with the sidewalls 13a, 3b, enabling the parts to withstand the high bending and/or torsional strains that may be created e.g. in the case of a hard piece of refuse being jammed between vane 6 and a stationary part of the structure.
  • the partition 14 serves to guide the pile of refuse positively through the entrance 13, 13" into the chamber 1 and prevents it from backsliding into the bin 5 through the open passage on the other side of the partition.
  • the hooping 15 and diagonal bracing 16 further strengthen the structure and stiffen it against asymmetrical forces developed at each reciprocation of the vane 6.
  • An inwardly directed flange 17 is preferably provided around the upper rim of bin 5 to oppose the overflow of rubbish from the bin during the movements of vane 6 therein.
  • the inner surfaces of crossbar 12, partition 14 and sidewalls 13a and 13b are, moreover, preferably provided with retaining or anchoring elements directed towards the chamber 1 for opposing the backflow of refuse into the bin 5.
  • Mechanism according to the invention for reciprocating the vane 6 is housed within the upper casing 10 and acts on the upper end of shaft 7 journaled therein.
  • Location of the vane-reciprocating mechanism at the upper rather than the lower end of shaft 7 as shown in FIGS. 1-5 has a number of advantages. Firstly such arrangement allows the upper rim of the bin 5 to be positioned lower than would otherwise be possible for a similar bin capacity, thereby facilitating the emptying of garbage cans into the bin 5.
  • the raised condition of door panel 2 and the structure supported thereby the
  • dead-center point of ram tilting moment exerted by the mechanism assembly 10 about the pivot axis 3 is smaller when said mechanism is positioned in the upper position shown in FIG. 1 than it would be if said mechanism were positioned beneath the bin.
  • the illustrated arrangement diminishes the power requirements for swinging the door to its raised position while also reducing the danger of the vehicle tipping about its rear axle during dumping operations.
  • the mechanism of the invention comprises two hydraulic rams including ram cylinders 18A and 18B pivoted at 19A, 19B at their outer ends to the casing 10.
  • the piston rods 20A, 20B of the rams are pivoted at their projecting or inner ends at 30A, 30B to respective arms 21A, 21B of a two-armed or forked crank member 21 secured to the vane shaft 7.
  • FIGS. 4 and 4a the mechanism of the invention comprises two hydraulic rams including ram cylinders 18A and 18B pivoted at 19A, 19B at their outer ends to the casing 10.
  • the piston rods 20A, 20B of the rams are pivoted at their projecting or inner ends at 30A, 30B to respective arms 21A, 21B of a two-armed or forked crank member 21 secured to the vane shaft 7.
  • the rams 18A, 18B are of the differential type in which the piston rods 20A, 20B are of appreciable cross-sectional area so that the inner cylinder chambers 23A, 23B are appreciably smaller in effective area than are the rear outer chambers 22A, 22B. The significance of this will presently appear.
  • both rams are operated at a constant-volume flow rate of delivery, then during each of the three phases the sum of linear velocities of the pistons in both rams remains unaltered.
  • both said linear velocities are relatively high and the resulting angular velocity imparted to vane 6 is correspondingly high. Because of the low effective cross-sectional areas in both rams, the torque imparted by the rams to the crank member is low, even though the effective moment arms of both rams at this time are relatively long.
  • both large-area compartments are under pressure and the piston velocities are therefore both small.
  • the leverages are large since both rams now extend in directions normal or nearly normal to the respective crank arms.
  • the angular speed of the vane is a minimum while the torque applied to vane shaft 7 is a maximum.
  • the third phase (and to a lesser degree the second) is an active phase in that the vane at this time is sweeping through its terminal rising arc through the bin and pushing before it a heap of refuse.
  • the first phase and also the second phase, at any rate in its first half, are idle return phases, during 'which the vane is not subjected to any substantial resistant torque from the [refuse in the bin.
  • the dual-ram mechanism of the invention makes it possible to achieve high velocity (with low torque) during the idle downward sweep of the vane, and high torque (with low velocity) during the active upward sweep, and thus provides optimum working conditions through the weeping cycle, while utilizing minimum power at a substantially constant value throughout each sweeping cycle.
  • each control-valve unit 27A, 27B is schematically shown in the form of an axially displaceable valve member or spool formed with passage therethrough for establishing variable hydraulic connections between lines externally connected to the respective valve casing (not shown) in which the valve spool is displaceable.
  • the external lines are shown as including two lines 42, 43, which as will later appear can be selectively connected to a pressure line P leading to a suitable hydraulic pump not shown and to an exhaust line B leading to a sump or reservoir; they also include two pairs of cylinder conduits 122A, 123A, and 122B, 123B, Which connect with the respective ram-cylinder compartments, analogously designated 22A, 23A and 22B, 23B in FIG. 4, through any suitable connecting means such as flexible hose or rotatable seal connectors, not shown.
  • FIG. 4a the two valve units 27A, 27B are shown superposed so as to appear as a single unit.
  • each unit 27A, 27B is displaceable in one axial direction (upward in FIG. 5, leftward in FIG. 4a) by a cam-follower roller 28A, 28B, engaging the contour of a respective cam 31A, 31B secured to the shaft 7, and is biased in the opposite direction into engagement with its cam by an associated spring 29A, 293.
  • Each of the cams 31A, 31B is in the form of a semicircular member having two arcuate sections of unequal radius, inter-connected by a ramp or incline, respectively designated 38, for cam 31A and 38 for cam 3113. The position of each connecting ramp 38 and 38 on its cam corresponds to alignment with the respective deadcenter axis 25, 26 earlier defined.
  • the arrangement is such that when ramp 38 is in engagement with the associated follower roller 28A, the corresponding ram 18A is positioned in alignment with the direction 25, and when ramp 38 is in engagement with its follower roller 28B, the ram 18B is positioned in alignment with direction 26.
  • roller 28A engages the large-radius arc of its cam 38A while roller 28B engage the small-radius arc of its cam 38B.
  • valve member 27A, 27B is axially displaceable between three operative positions.
  • FIG. 5 shows both members in their intermediate positions even though the two valves do not simultaneously occupy their intermediate positions in the normal operating cycle of the mechanism as will presently be understood.
  • valve member 27A in the upper operative position of this member as assumed by it when roller 28A is on the larger-radius arc of cam 31A, valve member 27A establishes connections (through passages 32) between cylinder conduit 123A and line 42 and between cylinder conduit 122A and line 43.
  • valve member 27A establishes connections (as shown) from both cylinder conduits 122A, 123A by way of a connecting passage 33 to line 42. And in the lowermost position of member 27A, when roller 28A is on the smaller-radius arc of its cam 38A, the connections established are from cylinder line 123A to line 43 and from line 122A to line 42.
  • the conditions are the same for the other valve unit 27B except that the relative positions of the cylinder conduits 1223 and 123B are reversed as compared to the cylinder conduits 122A and 123A, as shown.
  • valve unit 36 is displaceable between three positions, by means later described. In a first position (displaced to the left from the one shown in FIG. valve 36 makes connection from pressure line P to line 43 and from exhaust line E to line 42. In the other end position of valve member 36, these connections are reversed; while in an intermediate and transitory position, shown in FIG. 5, both lines 42 and 43 are directly connected to exhaust line E and are simultaneously also connected to pressure line P by way of a restricted orifice provided in the valve member 36.
  • roller 28A Since in this initial position roller 28A is on the larger-radius arc of cam 38A and roller 28B is on the smaller arc of cam 38B, the following connections are established: From pressure line P through passages in valve 36 to line 43 to inner cylinder compartment 23A (through valve 27A, raised) and to inner cylinder compartment 23B (through valve 273, lowered) and from exhaust line B through valve 36 to line 42 to outer cylinder compartment 22A (through valve 27A) and outer cylinder compartment 22B (through valve 27B). Thus both inner compartments 23A, 23B are under pressure and both outer compartments 22A, 22B are exhausted. Both rams operate jointly to rotate vane 6 clockwise from the position 6 by retracting their piston rods as earlier described.
  • reversal valve member 36 is shifted from its former (left-hand) position to its opposite (right-hand) end position.
  • Valve member 36 is shifted between its end positions by the alternate action of a pair of hydraulic plunger members 39 39 acting on its opposite ends.
  • Plungers 39 39 operate in respective pressure cylinders, not shown, whose outer compartments are connectable through lines 58 and by way of an auxiliary reversing valve member 35A with the pressure and exhaust lines P and E.
  • Auxiliary valve member 35A operates in an auxiliary valve casing 35 (see FIG.
  • both lines 42, 43 are momentarily connected in an intermediate position of member 36 through passage 41 with exhaust line B and also through restriction 40 with pressure line P.
  • This not only serves to prevent objectionable back pressure loading on the oil pump during movement reversal, but also completely unloads both cylinder cornpartments of both rams, so that the downward movement of vane 6 from its end position can be initiated by the action of gravity and/or the pressure of refuse acting on the upper surface of the vane, such vane movement being thereafter continued in the same direction by the action of the rams after valve 36 has reached its end position.
  • the vane shaft 7 has two diametrically opposed crank arms 45A, 45B secured thereto instead of the forked crank member of the first embodiment.
  • the mechanism is shown as being mounted underneath the bin 5 rather than in an overhead position, and the ram cylinders 18A, 18B have their outer ends pivoted at 19A, 19B to points near the lower outer corners of the swinging frame or door panel 2.
  • FIG. 6, and also that of FIG. 7, hereafter described is advantageous in cases where the mechanism may have to be mounted beneath the bin (rather than in the overhead position shown for the first embodiment) because it takes up less space longitudinally of the vehicle.
  • the angle formed between the crank-arm radii here is different from the angle 5 between the lines joining the axis of shaft 7 to the ram-cylinder pivots 19A, 19B.
  • the system is able to operate in a manner similar to the mechanism first described in enabling each of the rams to help the other ram cross its neutral'position.
  • both rams are able to develop concurrently a torque approximating the maximum possible torque during the upward sweep of the vane towards each of its end positions.
  • the control system associated with the mechanism of FIG. 6 for producing the desired changes in hydraulic connections during each cycle may be generally similar to that described with reference to FIGS. 4a and 5, mutatis mutandis.
  • FIG. 7 differs from that of FIG. 6 essentially only in that it is the rods rather than the cylinders of the rams 18A, 1813 that are pivoted to the fixed fulcra 19A, 19B, the cylinders being pivoted to the crank arms 45A, 45B at points 46A, 46B spaced from the ends of said cylinders.
  • the crank arms 45A and 45B are preferably formed as clevises with parallel spaced branches between which the bodies of the respective ram cylinders can pass. This arrangement has an advantage over that of FIG. 6 in that it makes it possible to increase the effective stroke of the rams as well as the leverage of each crank arm.
  • the control system for this modification may again be similar to that described.
  • the further modification of a two-ram mechanism shown in FIG. 8 includes a pair of single-acting rams 47A, 47B, both arranged exclusively for operation in traction.
  • the ram cylinders are pivoted to stationary points at 48A, 48B, while their piston rods 49A, 498 have flexible linkage elements 50A, 50B attached to their outer ends.
  • the flexible elements may assume .any suitable form, such as chains, cables, steel bands, belts, or the like. Both flexible elements have their free ends attached to an eccentric pin on a common crank arm 52 secured to shaft 7.
  • a tension-adjusting device 51A, 51B is interposed in each flexible link ahead of its attachment to the crankpin.
  • a pulley 53 Secured on shaft 7 adjacent to crank arm 52 is a pulley 53 which is adapted to receive in its peripheral groove one or the other of the flexible links 50A, 50B as the shaft 7 rotates towards one or the other of the end positions 6 or 6 respectively, of vane 6.

  • ram 47B is connected to exhaust while ram 47A is pressurized.
  • Piston rod 49A is thereby retracted and pulls on the link 50A.
  • Vane 6 is rotated counterclockwise. So long as link 50A remains in engagement with pulley 53 the rotation of the shaft 7 and vane 6 is relatively fast, and it will be noted that the ram cylinder 47A retains a constant angular position about its pivot 48A.
