The invention is generally applicable to a waste compactor. More specifically, the invention is applicable to a waste compactor including a monitoring system which enables an operator to view the interior or exterior of one or more portions of the waste compactor.
Waste compactors are used to compact waste and refuse materials to reduce the size and volume of the materials. It is desirable to compact waste and refuse materials for many reasons. For example, it is desirable to compact waste and refuse materials to reduce the space that is taken up by the materials in waste containers, dumps, landfills, etc. It is also desirable to compact waste and refuse materials to the reduce how frequently a waste container must be emptied, thus reducing the costs and effort associated with the emptying of the waste container.
It is desirable to provide a waste compactor which operates in an energy efficient manner. It is also desirable to provide a waste compactor which decreases the number of compaction cycles necessary to fill a given waste container with compacted waste and refuse materials. Furthermore, it is also desirable to provide a waste compactor which includes a monitoring system which enables an operator to view the interior of one or more portions of the waste compactor to: (i) promote safety and diminish the likelihood of accidental injury or death of an individual located within the waste compactor; (ii) increase the efficiency of the waste compactor by preventing unnecessary cycling of the compactor upon a determination that the compactor is not yet filled to capacity based upon a visual inspection of the interior of the waste compactor; and/or (iv) ensure that no obstructions are present in any portion of the waste compactor (e.g., charge box, container, loading chute, etc.). The present invention has applicability to a variety of compactors, including but not limited to self contained compactors, stationary compactors, vertical compactors, apartment style compactors, pre-crusher compactors as well as other compactor types.

Referring again to
The operation of the hydraulic cylinder or similar device is driven by a power unit (not shown) (which may include, for example, one or more hydraulic pump, hydraulic tank, electric motor, directional valves, etc.) and controlled by an electronic controller (not shown) (which may include, for example, one or more transformer, motor starter, relays, fuses, switches, circuit boards, programmable controllers, etc.) (not shown). The hydraulic ram moves horizontally, back and forth, within the charge box portion 104 and container portion 102. The hydraulic ram serves to force the waste material located within the charge box portion 104 into the container portion 102. Once the container portion 102 is sufficiently filled with waste material, the hydraulic ram then serves to compact the waste material within the container portion 102. After the completion of multiple, successive cycles of loading the charge box portion 104 with waste materials, forcing the contents of the charge box portion 104 into the container portion 102, and/or compacting the contents of the container portion 102, the container portion 102 will become filled. Once the container portion 102 is filled with compacted waste, the container portion 102 is then emptied.
The shape, orientation and configuration of the charge box portion 104 of the waste compactor 100 may vary in various embodiments. The charge box portion 104 may also have a variety of different sizes in various embodiments. The charge box portion 104 of the illustrated embodiment shown in
Referring again to
In the illustrated embodiment of the waste compactor 100, the waste compactor includes an optional loading chute 126. The loading chute 126 is adapted to allow a user 130 of the waste compactor 100 to load the charge box portion 104 of the waste compactor 100. For example, the loading chute 126 may be adapted to allow a user 130 of the waste compactor 100 to load the charge box portion 104 of the waste compactor 100 from the interior of a building or other structure. The loading chute 126 of various embodiments can have a variety of shapes and configurations. For example, the loading chute may have a generally rectangular or circular interior cross-section. Loading chute 126 may be constructed from a variety of suitable materials, such as one or a combination of metals, such as steel or aluminum, or one or a combination of thermoplastic or elastomeric materials. The loading chute 126 includes an inlet end which is accessible from the interior of a building other structure. The loading chute 126 of various embodiments of waste compactor 100 may traverse or pass through one or more walls 128 of a structure or other similar barriers to reach the location of the waste compactor 100.
In many embodiments of the waste compactor 100, the waste compactor is controlled by the user 130 without the user being able to view the interior of the charge box portion 104 and/or container portion 102. In additional embodiments of the waste compactor 100 which include a loading chute 126, the waste compactor is controlled by the user 130 from the interior of the building or other structure. In such embodiments, the user 130 often does not have a view of the waste compactor 100 or the interior of the charge box portion 104, container portion 102, and/or loading chute 126. In this manner, it is often necessary that the user 130 initiate the compaction of the charge box portion 104 without being able to view the interior of the charge box portion 104. Under these circumstances, it is possible that the compaction of the charge box portion 104 of the waste compactor 100 could be initiated with someone inside of the charge box portion 104 who is conducting maintenance of the charge box portion 104 or in the charge box portion 104 for some other reason. Without visualization of the interior of the charge box portion 104, it is also possible, that a user may initiate compaction of the charge box portion 104 prior to the charge box portion 104 being loaded to full capacity. The compaction of the charge box portion 104 prior to it being loaded to full capacity results in inefficiency due to the power consumption associated with a full compaction cycle even though the charge box portion 104 is not fully filled. Without visualization of the interior of the charge box portion 104, container portion 102, and/or loading chute 126, it is also possible, that an obstruction may go unnoticed that resides in the charge box portion 104, container portion 102 or loading chute and which should be removed for optimal operation of the waste compactor 100.
For this reason, it is desirable that the user 130 of the waste compactor 100 be afforded a view of the interior of one or more portions of the waste compactor 100. In the illustrated embodiment of the waste compactor 100 shown in
In addition, the user 130 can ascertain the fullness of the charge box portion 104 via the display 110 and ensure that a compaction cycle is not initiated until the charge box portion 104 is filled to full capacity, thus increasing the efficiency of the waste compactor 100 by eliminating any compaction cycles from occurring when the charge box portion 104 isn't fully filled. The user 130 can also determine via the display 110 whether the loading chute 126 and/or charge box portion 104 may be obstructed by waste material and whether any such waste material must be removed from the loading chute 126 and/or charge box portion 104 to permit for optimum performance of the waste compactor 100.
While the illustrated embodiment of the waste compactor 100 includes one camera 108 located within the loading chute 126 of the waste compactor, it should be understood that the camera 108 could be located within various other portions of the waste compactor 100. For example, the camera 108, could be mounted within the charge box portion 104, the container portion 102 or some other portion of the waste compactor. Also, additional embodiments of the waste compactor 100 may include multiple cameras 108 located at various positions around the exterior or within various portions of the waste compactor 100. Also, as mentioned previously, even though the illustrated embodiment includes only one display device 110, additional embodiments of the waste compactor may include additional display devices 110.
While the illustrated embodiment of the waste compactor 100 includes a loading chute 126, it should be understood that the monitoring system 106 of the present invention may be utilized with a wide variety of waste compactors 100. For example, the waste compactor 100 may be provided with an enclosure or room surrounding the charge box portion 104 to shield the charge box portion 104 from the elements. In such embodiments, the waste compactor 100 may include one or more cameras 108 located at various positions within the enclosure and/or the charge box portion to permit a view of the interior of the enclosure and/or charge box portion.
Also, as mentioned previously, while the detailed exemplary embodiments described in the specification and illustrated in the drawings relate to a self contained type compactor, in which a compacting unit is structurally integrated with a waste container, it should be understood that the waste compactor described herein has applicability to a variety of compactors, including but not limited to stationary compactors, vertical compactors, apartment style compactors, pre-crusher compactors as well as other compactor types.
