There have been known garbage manipulators where the loose garbage is directed into a receptacle and steered therefrom by means of a ram through a discharging passage into a garbage receptacle. The disadvantage of such prior art manipulators is in thefact that only a negligible compacting occurs during the steering of the loose objects through the discharging passage. Moreover, the taking up of the fed garbage by the ram was susceptible to disturbances, especially when an irregularly shaped or oversized object jammed the flow in the feed opening of the chamber.
It is therefore an object of this invention toovercome the disadvantages of prior art garbage manipulators.
More specifically, an object of this invention is to provide a compactor which compacts the incoming loose material to a predetermined, uniform density.
Another object of this invention is to provide a compactor which makes it possible to additionally compress the compacted package, thereby utilizing in the most economical manner the storage space of a garbage bag.
A further object of this invention is to provide a compactor which prevents clogging even if heterogeneous loose material is processed.
A still further object of this invention is to provide a great efficiency.
SUMMARY OF THE INVENTION According to this invention, the above objects are attained by providing a compacting chamber structure which has a feed opening and a discharge opening spaced apart from the feed opening, a gate movable in a plane for opening and closing the discharge opening and having means for self-cleaning the guiding grooves of the gate, operating means operable to compact at an adjustable pressure the loose material in the chamber to a predetermined density when the gate is closed and, respectively; to discharge the major portion of the compacted material through the discharge opening when said gate is subsequently opened. The operating means never passes beyond the plane of movement of the gate so as the rear end of the compacted material after discharge will be positioned near the plane of movement of the gate. The operating means is preferably a reciprocating hydraulic or pneumatic ram having on its upper part a tooth-like projection for separating oversized objects jammed in the feed opening of the compacting chamber. The gate is also controlled hydraulically or pneumatically by means of a programming switch in response to the movements of the hydraulic or pneumatic ram.
After the ram expels the compressed material from the chamber and starts back some of the material moves back slightly. It is folded and compacted with the bottom of the gate when'the gate comes down and the ram comes forward. The material held under the gate is again compressed at 90 to the gate and the ram folding it once more on the next approach.
BRIEF DESCRIPTION OF THE DRAWING For a better understanding of the invention together with other and further objects and advantages thereof, reference is made to the following detailed description taken in conjunction with the accompanying drawing, in which:
FIG. 1 isa sectional side view of an embodiment of the garbage compactor according to this invention;
FIG. 2 is a front view of a section of the garbage compactor of FIG. 1 taken along the line A-A;
FIG. 3 is a front view of another section of the compactor of FIG. 1 taken on the line BB; and
FIG. 4 is a simplified schematical diagram of an electrical programming device for controlling the operation of the hydraulic or pneumatic devices in the compactor of this invention.
DETAILED DESCRIPTION With reference to FIG. 1, there is shown a compacting chamber 8 having a feed opening 81, a discharge opening 82, a bottom 84, and an operating opening 83 for operating means. The feed opening 81 is preferably located on top of the compacting chamber 8 and communicates with a chute 9 for feeding the loose material; the discharge opening 82'is situated in a lateral wall of the chamber 8 opposite the operating opening 83. The bottom 84 of the compacting chamber 8 is leveled with the bottoms of the discharge and operating openings and it is extended beyond the operating opening 83 into a housing 34 for a hydraulic ram 3, as it will be explained later. In the plane of the discharge opening 82, a gate blade 7 is arranged for vertical movement in two upright guiding grooves 6 which are made preferably in the base of the funnel 10. To prevent the guiding grooves 6 from being clogged by the passing material, the grooves 6 terminate at a certain distance above the bottom 84 and the curved lower part 72 of the gate blade 7 projecting beyond the lower ends of grooves 6 is somewhat spaced apart from the base of the funnel 10, so that the resulting lateral steps 71 on the gate blade 7 can always expel the dirt which might accidentally enter the grooves 6. Similarly, to back up the gate blade 7 in its closed position the bottom of the funnel 10 is provided with ribs 85 arranged in a spaced relation one to another adjacent the plane of movement of the gate blade 7. The ribs 85 insure a sufficient backing up of the blade 7 when the latter is in its closed position and the spaces between the ribs can be swept clean by the passage of the compacted material. The ram 3 is preferably made in the form of an elongated box 3 which is supported on rollers 31 for movement across the compacting chamber 8 in the direction of the discharge opening 82.
According to one feature of this invention, the sweep of the reciprocating ram 3 is such as to enable the reinforced front plate 33 thereof to come to within approximately half an inch from the plane of movement of the gate blade 7 during the expelling position when the gate blade 7 is open.
According to another feature of this invention, the
upper portion of the ram 3 converges towards the feed opening 81, thus forming a tooth-like projection,
whereas the corresponding upper portion of the chamber 8 diverges towards the chute 9 (FIGS. 2 and 3). in this manner, the ram 3 can effectively cut off or releases oversized objects jammed between the chute 9 and the chamber 8. The lower portion of the box-like ram 3 corresponds substantially in shape to the lower portion of the chamber 8 and the ram 3 in its expelling position extends over theentire length of the chamber 8 but it does not enter the discharge opening 82. The gate blade 7 and the ram 3, with an adjustable pressure relief valve, are operated preferably by ahydraulic sys tem consisting of a hydraulic pump and a motor supplying hydraulic pressure through an adjustable pressure relief valve to two three-position four-way center tandem valves.
When the first valve is activated by an electrical signal it then advances the main ram cylinder to compress the material. When the signal stops the valve returns to a central position thereof and the oil flows through a center tandem port to the second valve. The solenoid of the second valve is then energized to shift the valve and activate the cylinder that opens the gate and then stop in the open position. The oil then momentarily flows through bothopen tandem ported valves back to the tank. The main ram cylinder valve is then again activated and the main ram continues to move forward to the end of the stroke ejecting the compressed material from the machine into the side compression area and eventually into the bag. The valve is then de-energized and the ram stops.
The gate valve is then energized to close the gate and the ram valve is energized to return at the same time. They then come to a complete rest with the gate down and the ram back awaiting the next cycle.
The hydraulic device 4 for driving the ram 3 is, with advantage, mounted within the interior of the box-like ram 3 and its piston 41 is terminated with a pushing boss 42 which is coupled to the front plate 33 of the ram 3. For this purpose, a bracket 43 is connected to the inside wall of the front plate 33 and it is provided with a U-shaped slot in which an end pushing boss 42 of the piston 41 is removably supported. 3 means of this arrangement, the compactor can be set up or dismantled in a considerably reduced time.
As shown in FIG. 4, the actuation of hydraulic devices 4 and 5, thus the operation of the entire compactor, is controlled by an adjustable electrical programming device 12, which comprises a material flow monitor including a monitoring photocell, an amplifier A and a switching relay; a timing cam driven by a motor to actuate in adjustable time intervals five switches; a hand operated main switch for the motor. of a hydraulic pump energizing the hydraulic devices 4 and 5; a starter for the motor of the hydraulic pump; a key operated switch having an of and an auto-operative position; and control solenoids for controlling the actuation of respective hydraulic devices of the compactor.
The sequence of operative steps of the compactor is as follows:
- gate blade 7 is in its closed position in the discharge opening 82; the main switch for the hydraulic pump motor is closed, and the key operated switch is turned from its of position to the "autooperative position;
- provided thatthe photocell of the material flow monitor attains its dark condition, signalling a sufficient load in the compacting chamber, the released signal activates via an amplifier A, a switching relay which in turn starts the motor for the time programming cam, thereby initiating the first working cycle, including the following sequence of working steps:
Upon the photo cell sensing a dark condition and the presence of material in the container, the amplified signal closes a relay completing the circuit to the hydraulic or pneumatic pump, disengages the timing motor brake and starts the timing motor. The first cam then engages the first timing microswitch to send the'ram 3 forward at a predetermined pressure in the pneumatic or hydraulic cylinder toachieve an adjustably set density and then stops. The timing motor continues to rotate the bank of five cams till it engages the fourth timing microswitch to open the gate and the second microswitch to continue the ram forward to the end of the stroke to expel the material into the side compacting area to further reduce the volume and increase the density of the discharged material.
It also moves the material one step closer toward placing it into the disposable bag. Then cams 3 and 5 engage assigned timing microswitches 3 and 5 to move .the gate down and the ram 3 back to the starting position for a new cycle. The ram 3'never passes beyond the compression plate and gate so that it will never have to cut garbage material or such matter. All mate rial that is lodged on the upper edge of the ram 3 and does not enter the discharge chamber is then transferred to the bottom of the chamber 8 when the gate 7 comes down. New loose material then can fall in front of the ram or be forced there by the gate. This feature will repeat until all such material will make an angular turn without being cut. The arrangement eliminates the need of excessive pressure or cutting knives or edges that would be required if the ram itself passed the bottom of the gate.
In the meantime the flow of waste material refills the compacting chamber and the flow monitor transmits a starting signal and the next working cycle is automatically repeated. The time of a cycle may be set, for example, for forty seconds.
I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art. For example, it has been found that the machine operates flawlessly even if the backing ribs are removed from the funnel 10.
