  • This invention relates generally to refuse compacting devices and more specifically, to a fluid power system for use in refuse compacting devices.
  • Refuse compactions devices of the type using a reciprocating compaction ram generally fall into two categories.
  • the first utilizes a ram to compact refuse into a closed chamber wherein a bale of refuse is ejected from the chamber after compaction by forward movement of the ram into the chamber.
  • This type of compaction device is usually used in large installations where the bales of refuse are loaded into truck bodies or portable containers. Large volumes of refuse can be handled and the available space in the truck body or container can be efficiently utilized.
  • the second type of compaction device ejects a substantially continuous mass of compacted refuse by moving a ram to force refuse through a funnel shaped opening. The pressure of the ram forces the refuse through the funnel causing compaction by extrusion and eventually ejection through the smaller end of the funnel.
  • the main ram is driven forward by a hydraulic cylinder and, upon occurrence of a jam, the small auxiliary ram is forced forward through a separate hydraulic system in an attempt to break up the jam ahead of the main ram.
  • Devices of this type have been successful, however, they increase the cost of the compactor unit, in that they require separate hydraulic systems for each ram and a control system associated therewith.
  • the present invention is usable in both closed chamber and funnel type of compactors and eliminates the need for separate hydraulic systems for the main ram and the jam clearing or auxiliary ram while, at the same time, maintaining the operation and function of each ram.
  • One hydraulic system can be used to drive both the main ram for compaction purposes and the auxiliary ram for jam relieving purposes.
  • FIG. 1 is an isometric view of a funnel type refuse compacting device with portions broken away to show internal structure
  • FIG. 2 is a cross sectional view of a compaction ram and the fluid cylinders used in the compacting device shown in FIG. 1;
  • FIG. 3 is a sectional view of the rams and fluid cylinder of the compactor shown in FIG. 1, with the main ram in the extended position;
  • FIG. 4 is a cross sectional view of the rams and fluid cylinders of the compactor shown in FIG. 1, with the main ram and the auxiliary ram in the extended position;
  • FIG. 5 is a diagramatic representation of a hydraulic system usable with-the present invention.
  • FIG. 6 is a diagramatic representation of an electrical circuit usable with the present invention.
  • the invention is disclosed herein in a ram and funnel the invention is applicable to any type of compactor which utilizes a main compaction ram and an auxiliary or jam clearing ram.
  • FIG. 1 receives refuse material from a chute 2 wherein waste material is accumulated prior to compaction.
  • the chute deposits refuse or waste material into a compaction chamber 4 enclosed in an elongated casing or body 6.
  • the compactor assembly is usually mounted on a foundation or base indicated generally as 8. Waste material deposited in the chute 2 falls into the compaction chamber 4 and is subsequently compressed and forced through an exit opening 10 into a funnel shaped member 12.
  • the large end of the funnel 12 receives refuse material from the exit opening 10, and as the material is extruded through the funnel into the smaller end, it is compacted for subsequent disposal.
  • a main compaction ram 16 which is capable of traversing the compaction chamber 4 to force waste material into the funnel 12.
  • An auxiliary ram 18 is mounted in the center of the main ram 16 and is utilized to clear jammed waste material ahead of the main ram and may also be used to force waste material into and through the funnel 12 at the end of the stroke of the main ram. It is not essential to the operation of the present invention that the auxiliary ram be located in the center of the main ram. Particularly in compactors of the type wherein the ram is not cylindrical, it may be desirable to locate the auxiliary ram in a position other than the center of the main ram.
  • auxiliary ram comprises the cylinder portion of the hydraulic system used to drive both the main ram and the auxiliary ram.
  • the main ram, the auxiliary ram, the piston rod and an intermediate section all telescope together to provide a compact unitary fluid power system to drive the rams through the compaction chamber.
  • a fixed rod 20 which serves as a hydraulic piston and as a fluid line is secured to the rear of the casings 6 by means of a pivotal connecting bracket 22.
  • the rod 20 has a pair of hydraulic ports 24 and 26.
  • the port 24 is the fluid inlet port for the extend mode of operation and the port 26 is the drain port in the extend mode. In the return mode of operation the port 26 becomes the inlet port and the port 24 becomes the drain port. In each mode of operation the inlet port is connected to high pressure fluid and the drain port is connected to a fluid reservoir tank.
  • the rod 20 has a hollow interior which forms a fluid passage chamber 28.
  • the fluid passage chamber is connected to the port 26 while a fluid line 30 is connected to the port 24 and extends through the passage chamber 28 and through the head end 32 of the rod 20.
  • An intermediate section 34 of tubular shape surrounds the rod 20 and serves as a hydraulic cylinder relative to the piston function of the rod 20.
  • the intermediate section 34 is comprised of a cylindrical shell 36 and a head 38 which hydraulically seals the forward end of the cylinder.
  • the fluid line 30 is opened to a chamber 40 formed between the head 38 of the intermediate section and the head 32 of the rod 20.
  • There are sealing rings or bushings 42 at the rear of the intermediate section 34 and sealing rings 44 at the forward end of the rod 20 which serve to hydraulically seal the fluid in the chamber 40 and in an intermediate expansion chamber 46 formed between the interior surface of the intermediate section 34 and the outside surface of the rod 20. Sealing rings or bushings 42 and 44 also serve to guide the movement of the intermediate section 34 relative to the rod 20.
  • the sealing rings 42 are secured to the inside of the intermediate section 34 while the sealing rings 44 are secured to the outside of the rod 20.
  • the shell 48 of the main ram 16 is secured to the intermediate section 34 by means of a rigid connecting rod 50.
  • the means of connecting the intermediate section 34 to the main packer ram 16 is illustrative only. Any suitable rigid connection may be used. As shown herein, however, the rod 50 is connected to the inside of the shell 48 and to a connector ring 52 secured about the outer surface of the intermediate section 34 at the rearward portion thereof. Linear movement of the intermediate section 34 will produce a corresponding movement in the main packer ram 16 by means of the connecting rod 50.
  • the auxiliary packer ram 18 is concentrically mounted about the intermediate section 34 and comprises an outer shell or casing 54 and a compaction head 56.
  • the compaction head 56 and the intermediate section head 38 form an expansion chamber 58 within the inner diameter of the auxiliary ram 18.
  • the intermediate section head 38 has a sequence valve 60 and a check valve 62 interconnecting the expansion chambers 40, 58. The operation of the sequence valve 60 and the check valve 62 will be described in more detail below.
  • a fluid drain line 64 extends from the sequence valve 60 through the rod head 32 to the passage chamber 28.
  • the line 64 is mounted for sliding movement at the point where it passes through the head 32.
  • the line 64 is of a length sufficient to allow the end of the line to be in the chamber 28 when the compactor is in the fully extended position.
  • the outer surface of the intermediate section 34 forms one wall of a third expansion chamber between the intermediate section 34 and the auxiliary packer ram 18.
  • Chamber 70 is sealed by a sealing ring or bushing 66 secured to the rear inner wall of the auxiliary ram 18 and a bushing or sealing ring 68 secured to the outer forward surface of the intermediate section 34.
  • the expansion chamber 40 is essentially the head end of the hydraulic cylinder.
  • the high pressure fluid acts against the inside of the head 38 of the intermediate section or cylinder 34 and against the head 32 of the rod 20. Since the rod 20 is fixed at bracket 22 the intermediate cylinder 34 advances to the right, as seen in FIG. 3.
  • the intermediate section or cylinder 34 carries the main packer ram 16 and the auxiliary ram 18 forward until the position shown in FIGS. 1 and 3 is reached. That is, the main ram traverses the compaction chamber 4 forcing refuse forward through the funnel 12.
  • sequence valve 60 is set for a predetermined pressure which, when encountered in the chamber 40, will allow the fluid to pass through the head 38 of the intermediate cylinder. High pressure fluid passing through the sequence valve 60 into the expansion chamber 58 forces the auxiliary ram 18 forward ahead of the main ram 16. At this point the intermediate cylinder 34 acts as a piston relative to the auxiliary ram 18. The intermediate section 34 remains stationary and the auxiliary ram 18 is forced forward by the action of the high pressure fluid in the chamber 58. The auxiliary ram will move forward into the jammed refuse material clearing the jam and forcing part of the refuse material forward into the funnel 12.
  • High pressure fluid entering port 26 provides pressure to the passage chamber 28.
  • the high pressure in the passage chamber 28 passes through a port 74 extending between the passage chamber 28 and the expansion chamber 46 between the rod and the intermediate cylinder 34.
  • High pressure fluid in the expansion chamber 46 acts on the bearings or seals 42, 44, causing the intermediate cylinder 34 to be moved in the rearward direction.
  • the high pressure fluid acting on the smaller surfaces of the bearings 42, 44 is sufficient to overcome the low pressure fluid in chamber 40 acting on the end of the rod 20 and the inside of the head 38.
  • the chamber 40 decreases in size and fluid in the chamber 40 is forced through the line out the port 24 to the reservoir.
  • the high .pressure fluid in the passage chamber 28 passes through the fluid line 64 to the sequence valve 60 assuring that the sequence valve 60 closes at the same time the switch SW-3 is closed.
  • the rearward movement of the intermediate cylinder 34 causes the main ram 16 to be, withdrawn back through the compaction chamber 4 to its original or starting position.
  • the rearward movement of the intermediate cylinder 34 moves a port 76 into open flow relationship with the expansion chamber 46.
  • the port 76 is in the outer wall of the intermediate cylinder 34 and provides a fluid opening between the expansion chamber 46 and the expansion chamber 70 formed between the outer surface of the intermediate cylinder 34 and the inner surface of the auxiliary ram 18.
  • High pressure fluid in the chamber 70 acts against the bearings 66, 68 to produce rearward movement of the auxiliary ram 18.
  • the action of the high pressure fluid against the surfaces of the bearings 66, 68 is sufficient to overcome the action of the fluid in the expansion chamber 58 acting on the head 38 of the intermediate cylinder and the head 56 of the auxiliary ram.
  • the fluid pressure build-up in the chamber 58 by the rearward movement of the auxiliary ram 18 is released through the one-way check valve 62 to the chamber to the fluid line 30 and the port 24.
  • the high pressure fluid in the chamber 70 continues to move the auxiliary ram rearward until the auxiliary ram is again positioned inside the main ram, as shown in FIG. 2.
  • the compactor is then in position to be recycled for further compaction of the material in the compaction chamber 4.
  • the passage chamber 28 and the fluid line 30 of the hydraulic cylinder rod 20 are connected to a fluid pump 78 through a hydraulic four-way directional valve 80.
  • the pump 78 is driven by a motor 82 and pumps fluid from a reservoir 84 through line 86 to the four-way directional valve 80.
  • a hydraulic line 88 connects the four-way directional valve to the fluid line 30 of the rod 20 and a hydraulic line 90 connects the fourway valve to the passage chamber 28 in the rod 20.
  • a system relief valve 89 is provided in the line 86 to prevent excessive pressure build-up in the system.
  • a spring 92 holds the four-way directional valve in a straight through position wherein the pump 78 pumps fluid through the line 86, through the four-way directional valve to the line 88 leading to the fluid line 30 of the rod 20. In this position fluid is free to move from the expansion chambers 46, through line 90, through the four-way directional valve back to the reservoir 84.
  • a solenoid sol-l has its plunger connected to the four-way directional valve 80 to actuate the valve to a position wherein fluid from the pump 78 will pass through the line 86 to the four-way directional valve, through the four-way directional valve to line I leading to the passage chamber 28.
  • Hydraulic fluid in the expansion chambers 40, 58 is free to move through the fluid line 30, through the line 88, through the fourway directional valve 80 back to the reservoir 84.
  • a pressure switcls 94 is mounted in line 86 or 90 to respond to excess pressure in the system to disconnect solenoid sol-l, allowing the spring 92 to reverse the position of the four-way directional valve.
  • a light or sonic sensing switch 96 is mounted in the hopper 2 to detect the presence of refuse in the hopper and initiate operation of the compactor.
  • the switch 96 has contacts SW-s mounted in the main power line to the compactor. When the light or sonic beam is broken, the contacts SW-s close, energizing the compacting circuit.
  • a master switch SW-Ml is also mounted in the main power line to the compactor so that the entire compactor may be shut downv to prevent operation at any time. The master switch SW-Ml must be closed prior to operation of the compactor.
  • a manual switch SW-M2 is mounted in the compactor circuit in parallel with the contacts SW-s of the sensing switch 96, to allow manual operation of the compactor. In the event there is insufficient refuse in the hopper 2 to actuate the sensing switch 96, the compactor may be operated by manually closing the switch SW-M2.
  • the relay R1 has a set of normally open contacts Rl-l which are in parallel with the contacts of the sensing switch SW-s and the manual switch SW-M2 and which provide a holding circuit for the relay R1. Operation of the compactor allows the refuse in the hopper 2 to be depleted and the beam of switch 96 to be restored.
  • the contacts SW-s are normally open, cutting off power to the compactor circuit.
  • the holding circuit and the contacts Rl-l maintain power to the circuit throughout the cycle of operation.
  • the counter 98 can be set to allow a predetermined number of cycles of operation prior to de-energizing relay R1 which, in turn, opens contacts Rl-l to shut down the compactor.
  • the counter 98 is pulsed by sets of contacts to switches SW-l and SW4.
  • the switch SW-l is a limit switch located on the inside of the casing 6 at a position to be actuated by the return movement of the main ram 16.
  • the switch SW-4 is located on the intermediate cylinder 34 and is actuated by the auxiliary ram 18. Both SW-l and SW-4 must be closed to pulse counter 98, therefore, both the main ram and the auxiliary ram must be in the start of cycle position withdrawn from the compaction chamber.
  • the counter would be set to operate five cycles each time the sensing switch 96 is interrupted. Each time that the main ram 16 and the auxiliary ram 18 return to their retracted position they would actuate switches SW-] and SW-4 pulsing the counter 98.
  • Closing of the sensing switch SW-s also energizes the motor 82 and provides power to a second relay R2 through a second set of contacts to switch SW-l.
  • the line to relay R2 also has two sets of normally closed contacts for a second limit switch SW-2 and a third limit switch SW-3 mounted in series with the relay R2 and in parallel to the contacts oflimit switch SW-l.
  • the limit switch SW-2 is mounted in the compaction chamber 4 in a position to be actuated by the main ram head at the end of the compaction stroke.
  • Relay R2 has two sets of contacts, the first set R2-l being normally open and mounted in the line to relay R2 parallel to contacts of switch SW-l. Contacts R2-l provide a holding circuit for the relay R2. A second set of contacts R2-2 for the relay R2 are also normally open and control the power to the solenoid sol-l.
  • main ram 16 Prior to operation, main ram 16 is in the retracted position shown in FIG. 2 and the switches SW-l and SW-4 are held in a closed position.
  • the circuit to the switch 96 is interrupted and the normally open contacts SW-s are closed, energizing relay R1 and providing the holding circuit through contacts Rl-l.
  • the motor 82 is energized, driving pump 78 to provide high pressure fluid to the system from reservoir 84.
  • the relay R2 With the switch SW-l in a closed position, the relay R2 is energized, closing the holding circuit through contacts R2-1 and the circuit to solenoid 501-1 through contacts R2-2.
  • the four-way directional valve 80 With the solenoid energized, the four-way directional valve 80 is moved to the position wherein high pressure hydraulic fluid is supplied to the fluid line 30 and to expansion chamber 40. Fluid in the expansion chamber 40 forces the intermediate cylinder 34 forward carrying the main ram 16 through the compaction chamber. Forward movement of the main ram 16 releases the switch SW-l allowing the contacts of switch SW-l to return to their normally open positions.
  • the solenoid sol-l continues to be energized by means of power through contacts SW-2, SW-3 and R2-l to relay R2 and through contacts R2-2 to the solenoid sol-1.
