Definitions

  • This invention relates to a packer assembly, and more particularly to a packer assembly adapted for use with a refuse collection truck of the type commonly employed to ⁇ gather refuse from a plurality of collection points for transportation to a dump or incinerator. More particularly, this invention relates to -a refuse packer assembly susceptible of extremely economical construction which is adapted to utilize fully the refuse carrying capacity of the collection truck by providing for highly efficient loading of the truck, and eliminating improper and uneconomical loading conditions encountered with the use of certain packer assemblies heretofore known, wherein voids or empty spaces remain unfilled in the body of the truck.
  • This invention relates further to a packing assembly as aforesaid which is automatically shifted through a cyclical packing movement without manual application other than the initial manual operation of actuating the assembly and the final operation of shutting o the assembly.
  • this invention relates to a cyclically operating packing assembly adapted, upon encountering of an obstruction in any cyclical movement, automatically to shift to the next cyclical movement without completing the prior obstructed movement, thereby preventing overloads on the packer assembly and its associated operating mechanism, and also eliminating the necessity for manually retracting the packer assembly from an obstructed movement, a procedure necessary with other packing assemblies heretofore known.
  • This invention relates further to a packer assembly adapted to be used in conjunction with a truck having an escalator type loader or the equivalent, the packer assembly functioning in such combination primarily as a load distributor to implement filling of the truck body portions, to avoid a condition often encountered with such escalator loaders wherein voids or waste payload spaces reduce the operating efficiency of the truck.
  • a further object of this invention is to provide a refuse packing device which, with a minimum of supervision, provides automatic loading and safety features which might be achieved in devices heretofore known only through constant supervision by operating personnel.
  • a still further object of this invention is to provide a refuse packing assembly adapted automatically to cornpensate for relatively infrangible, difficulty crushable or movable objects encountered in the path .of the packer mechanism and to shift the said mechanism out of the path of the object encountered and continue the packing cycle, thereby preventing damage to the packing mechanism and associated operating members, which might otherwise occur if packing operations were continued without removing manually the interfering object from the path of the cycling packing member.
  • Still a further object of this invention is the provision of a hydraulic control means adapted to be initially manually operated and thereafter to cyclically shift a packer plate assembly through a cycle of packing movements arranged to transfer from a loading compartment outside of the body of the truck refuse manually deposited in such loading compartment, inwardly within the storage compartment of the truck body.
  • Still a further object of this invention is to provide a hydraulic actuating mechanism arranged to shift a packer plate through a cyclic series of packing movements, initiation of each successive movement being responsive to pressure increases or build ups in the hydraulic mechanism which actuated the packing plate through the prior movement.
  • Still a further object of this invention is to provide a packer plate cyolically movable by hydraulic means arranged to actuate said plate through a cycle of packing movements delined by the extensible and contractible limits of the hydraulic actuating means.
  • Still a further object of this invention is to provide a packer assembly wherein a packer plate actuated by a -plurality of hydraulic motor means is sequentially shifted through a cycle of packer movements by alternate actuation of the said motor means, such alternate actuation being effected responsive to pressure increases in the motor means, such as occur in the limiting positions of said motor means, and such as occur also when said packer plate encounters a relatively immovable obstacle intermediate the limiting positions of said plate.
  • Still a further object of this invention is to provide a hydraulically operated packer plate arranged to be automatically shifted through a normal packing cycle and arranged automatically to abbreviate one or more movements of said normal packing cycle upon encountering, during such movement, a relatively immovable obstacle.
  • a further object of this invention is to provide ya packer assembly having the aforesaid characteristics and being especially adaptable for use in combination with escalator or other high level type loaders as a distributing means to prevent the formation, adjacent the escalator discharge area, of blocking heaps, and to assure compaction and relatively even distribution in the body of the truck of refuse deposited by such high level type loaders.

  • the element P represents a hydraulic pump and reservoir system for providing the hydraulicV fluid under pressure necessary fordriving the motors 30, 40 and ⁇ 41.
  • a main relief valve VMR is interposed between the pump P and the main controlvalve VMC to guard against acciden-tal overload and consequent damage to the system.
  • the diagraml of FIGURE 6 illustrates4 the packer plate in the beginning or storage position shown inv FIGUREV 2, the control of the main valve VMC having just been thrust to the forward position thereof.
  • the double active hydraulic cylinder members 30 and control Vcylinder members CC1 and CC2 each should be conin the inward or contractile position thereof.
  • V main control valve VMC When theV main control valve VMC is manually shifted Yto' the for- Ward ⁇ or F position, hydraulic uid is permitted to flow through the lines A, A1 and A2 to the sequence valves SV1 and SV2, respectively.
  • the valves SV1 and SVZ will lie, respectively, in the forward and rearward positions as' shown in FIGURE'.
  • valve RV1 With the valve RV1 ⁇ thus opened, fluid is admitted to the control line C1, thereby introducing Huid under pressure behind the piston ⁇ in control cylinder CC2, causing extension ⁇ of the piston P2, thereby advancing the operating member of sequence valve SV2 to the forward or F position thereof.
  • the valve SVZ thus in the forward position, Huid from the line A2
  • shifting from one cyclic movement of the packer plate to the next is effected responsive to pressure increases in the hydraulic moving means, which pressure increases are, during normal operation of the packer device, occasioned by limited expansibility or contractability resulting from a reaching of the end or limiting stroke ⁇ of the hydraulic motor means. If, during a movement of the packer plate, a relatively incompressible object of refuse or the like is encountered or wedged by the packer plate against the frame of the truck, further expansion or contraction of the moving hydraulic cylinder Will be impeded and pressure will increase in the cylinder in the same manner as above described at an end limiting stroke of a piston with respect to the cylinders.
  • the series of pressure sensitive relief valves RVI, RVZ, RVS, RV4 may be set to act at a pressure sufliciently low to prevent damage to the hydraulic system and the operating and packing parts, without permitting pressure build ups suicient to actuate the main relief valve VMR.
  • the packed plate 24 may be operated through a reverse cycle, such operation being desirable as an aid in clearing stubborn obstacles or the like rearwardly out of the temporary loading storage compartment 14.
  • the operating handle of the main control valve VMC is moved to the R position, permitting uid to flow through the line B to sequence valves SVI and SVZ.
  • relief valve RVZ opens, actuating the control cylinder CCI, causing sequence valve SVI to be shifted to the R position, thereby permitting the ow of fluid through the line L to the cylinder 36 and extending the piston member 31, gradually to move the packer plate to the limiting position shown in FIGURE 4.
  • relief valve RVi will activate control cylinder CC2, extending piston P2 and shifting sequence valve SV2 to the F on forward position. In such position, fluid flows through line M to the cylinders 40, 41, extending the pistons 46, 47 and gradually moving the plate 24 to the position shown -in FIGURE 3.
  • relief valve RV4 On reaching such position, relief valve RV4 is overloaded, thereby withdrawing the piston P1, shifting the sequence valve SVI ⁇ to the forward position, thereby permitting fluid to ow through line O, contracting the piston member 31 to 'a position within the cylinder 30, 'and thus moving the plate to the final positiion shown in FIGURE 2, at which position the relief valve RV3 will function to cause control cylinder CCZ to withdraw piston P2 and valve SVZ to Ithe R position, which is the initial position as shown in FIGURE 6.
  • a check valve (not shown) is connected in parallel, bypassing relation with each ⁇ of the relief valves RVI, RVZ, RVS, RV4.
  • Such check valves are oriented to permit flow only in a direction opposite to :the direction of ow permitted by the corresponding relief Valve, but permits ilow around such relief valve of fluids within the control cylinder chambers displaced upon shifting of the control cylinder pistons.
  • a further important feature of the device which aids in its ability to clear itself ⁇ of obstacles encountered during a stroke is ⁇ the fact that even after encountering by the plate of an obstacle in a given path of movement and consequent recycling of the plate as heretofore described, the plate is nevertheless urged, during the recycles or short-cycled movement, in the direction of the blocking obstacle and, thus, for instance, if an obstacle is encountered by the plate 24 as it moves from the position shown in FIGURE 3 to that shown in FIGURE 4, thus causing premature withdrawal of the piston 3l to a position within the cylinder 30, the pistons 46 and 47 nevertheless tend to contract during the upward movement of the piston 3'1.
  • the described packer assembly 7 may be used cyclically or alternately in conjunction with a high level loader assembly as a load distributor rather than as the prime loading member illustrated in the refuse truck of FIGURES l to 5.
