The invention relates to waste and refuse removing and hauling vehicles. More particularly, the present invention relates to waste and refuse removing and hauling vehicles having an on-board communication system for controlling, tracking, and monitoring movement of a waste or refuse receptacle relative to the vehicle.
The collection and transportation of trash and recyclables from residential, commercial, industrial and large residential facilities is a major industry in the United States and throughout the civilized world. Typically, trash and recyclables are accumulated and temporarily stored in waste material receptacles such as trash cans and dumpsters. When filled, or at regularly scheduled intervals, trash and recyclables from the containers are transported for the eventual recycling, incineration and/or disposal into landfills.
Customers typically pay for trash and recyclables removal services based on the amount of trash and recyclables removed and the number of trash and recyclables pickups over a period of time. The compacting of trash and recyclables at a customer's location typically reduces the number of pickups. A successful trash and recyclables compactor is disclosed in U.S. Pat. No. 6,412,406, titled Trash Compactor and owned by Advanced Custom Engineered Systems & Equipment, Inc., Carol Stream, Ill.
These industrial, commercial and large residential bins and compactors are collected from different locations and hauled to a central location. Normally, those hauling the trash and recyclables are sent from a central location and dispatched to the different locations. In practice, paper logs or schedules document the hauler's runs (e.g., trash and recyclables to pick-up, trash and recyclables being picked-up, and trash and recyclables picked-up). The haulers are given their routes in person or over the phone. The haulers, in turn, keep in touch with the central location generally by cell phone or radio.
For large organizations this can be a very complicated task as there are many haulers and many customers needing their trash and recyclables collected, picked-up and hauled away. In addition, commercial, industrial and large residential (e.g., condos and apartment buildings) trash and recyclables compactors and balers must be monitored for maintenance and repair. This too requires time and energy for the haulers and/or representatives (of the service provider) to monitor and inspect.
It should also be recognized that these industrial, commercial and large residential bins, balers and compactors require both period maintenance and emergency demand repair services. Normally, those repairing the equipment are sent from a central location and dispatched to the different locations. In practice, paper logs or work orders document the repairperson's time (e.g., drive time, time spent performing the repairs, parts and materials used, etc.). The repair companies use a variety of management tools. For example, some are given their routes in person or over the phone. The service providers, in turn, keep in touch with the central location generally by cell phone or radio.
For large organizations this can be a very complicated to coordinate and to verify that the charges for these services are fair and accurate as there are many service providers and many customers needing their compactors, bins and balers repaired. In addition, commercial, industrial and large residential (e.g., condos and apartment buildings).
In addition, it must be recognized that trash and recyclables compactors, balers and bins must further be monitored for maintenance and repair.
Methods of improving the refuse collection are disclosed in commonly assigned and copending U.S. Patent Application Publication No. 2008-0197194 A1, published on Aug. 21, 2008; U.S. Patent Application Publication No. 2008-0198021 A1, published on Aug. 21, 2008; and U.S. Patent Application Publication No. 2008-0202357 A1, published on Aug. 28, 2008. These publications are hereby incorporated by reference as if fully set forth herein, and generally disclose systems for communicating with receptacles, etc.
One opportunity that exists with refuse removal is to improve communication between the vehicles making refuse pick-ups (emptying receptacles) and the central station or dispatcher. Currently, the dispatcher may be in contact with the vehicle via radio or telephone transmission. However, it is not cost-effective of feasible for the dispatcher to be in constant contact with every vehicle out in the field. Thus, it is impossible for the dispatcher to relay account information associated with each receptacle to a vehicle. In would be advantageous to provide such information to the vehicle to prevent pick-up and emptying of receptacles owned or managed by entities delinquent in their payment of invoices. Also, a given account may have special instructions, such as an additional oversized pick-up, for a discreet single day or event. The dispatcher currently has no way of assuring that the special instructions are provided to the vehicle in a timely manner.
Furthermore, there is on-going and growing concern in major municipalities with controlling several aspects refuse collection. For instance, citizens or users will often engage in activity with respect to refuse receptacles that violates municipal codes. Some of this is caused by simply overloading receptacles. Other times, a user may fall behind in payment of bills for removing refuse and waste, and the receptacles and surrounding areas will become over loaded with refuse. This provides a haven for vermin such as rats. It may also cause damage to the lane on which the receptacles are located.
Absent constant patrol of back lanes, municipalities often have no idea that these conditions exist until it is too late. Even when patrolling the back lanes, it is difficult to impossible to determine which receptacles belong to which owners/addresses. Finally, when a positive identification of the offending receptacle is able to be determined the process consumes so much time that the municipal employee is only able to investigate but a handful of the many violations that occur at any one time. Thus, city officials need a method that will facilitate receptacle identification while at the same time providing a simplified method of issuing citations to the proper entity responsible for the code violation.
The present invention is provided to solve the problems discussed above and other problems, and to provide advantages and aspects not provided by prior waste and refuse collection systems and apparatuses of this type. A full discussion of the features and advantages of the present invention is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
One aspect of the present invention is directed to a vehicle for removing and hauling waste. The vehicle comprises a waste bin, a waste receptacle transfer means, and a first receiver. The waste bin is located above a baseline and has a chamber and an emptying site. The waste receptacle transfer means is driven from a first position associated with the baseline to a second position associated with the emptying site of the waste bin and back to the first position. A waste receptacle is temporarily retainable to the waste receptacle transfer means and transferrable by the waste receptacle transfer means from the first position to the second position to spill or empty a contents of the waste receptacle into the waste bin at the emptying site and back to the first position. The first receiver is associated with the first position for receiving a signal generated by the waste receptacle at a first moment in time when the waste receptacle transfer means is in the first position and at a second moment in time when the waste receptacle transfer means has returned to the first position from second position.
A second aspect of the invention is directed to a vehicle for removing and hauling waste. The vehicle comprises a waste bin, a receptacle transfer means having a motorized arm extending outwardly from the vehicle, and first and second receivers. The waste bin is located above a baseline. The waste bin has a chamber and an emptying site. The arm of the transfer means is driven from a first position associated with the baseline to a second position associated with the emptying site of the waste bin and back to the first position. A waste receptacle is temporarily retainable to the arm and transferrable by the arm from the first position to the second position to spill a contents of the waste receptacle into the waste bin at the emptying site and back to the first position. The first receiver is associated with the first position of the arm for sensing a signal generated by the waste receptacle. The second receiver is associated with the second position of the arm for sensing the signal generated by the waste receptacle.
A third aspect of the invention is also directed to a vehicle for removing and hauling waste. This vehicle comprises a waste bin, a waste bin transfer means, and a first receiver. The waste bin is located above a baseline and has a chamber and an emptying site. The waste bin transfer means is driven from a first position associated with the baseline to a second position located above the baseline on the vehicle, wherein the waste bin is temporarily retainable to the waste bin transfer means and transferrable by the waste bin transfer means from the first position to the second position to fix the waste bin at the second position on the vehicle for transporting the waste bin to a new location. The first receiver is associated with the first position for sensing a signal generated by the waste bin at a first moment in time when the waste bin is in the first position.
Other features and advantages of the invention will be apparent from the following specification taken in conjunction with the following drawings.
To understand the present invention, it will now be described by way of example, with reference to the accompanying drawings in which:
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
Referring to
Each receptacle 100 is outfitted with a means of communicating or transmitting a signal carrying an identifier associated with the receptacle 102, such as a radio frequency identification (RFID) tag. RFID tags are well-known in the retail industry for identifying products. In particular, an RFID tag or transponder is an object applied to or incorporated into a product for the purpose of identification using radio waves. Most RFID tags contain at least two parts, namely an integrated circuit for storing and processing information, modulating and demodulating a (RF) signal and an antenna for receiving and transmitting the signal. RFID tags come in three general varieties: passive, active, or semi-passive (also known as battery-assisted). Passive tags require no internal power source, thus being pure passive devices (they are only activated when a reader is nearby to power them), whereas semi-passive and active tags require a power source, usually a small battery. While the present discussion focuses on passive RFID tags, it is recognized that a similar system can be used for active and semi-active RFID tags.
The RFID tags may transmit high frequency (HF) signals, low frequency signals (LF), or ultra high frequency (UHF) signals. The characteristics of these signals differ, and one particular frequency may be more advantageous than another based on the particular application of the system. For instance, low frequency signals have a short read range (distance) which would prevent errors or false reads. UHF signals can have a read range that is very short to very wide (any yards or meter).
While RFID, and in particular passive RFID tags are discussed herein, it is recognized that other identifying or alerting tags can be used. Many are known and perhaps others in the future. For example, electrical article surveillance (EAS) tags can be used. EAS tags are commonly used to prevent shoplifting from retail stores. The EAS tags are attached to merchandise and are removed or deactivated by the clerks when the item is properly bought or checked out. At the exits of stores, a detection system sounds an alarm or otherwise alerts the staff when it senses active tags. These tags are typically made of a strip of amorphous metal (metglas) having a low magnetic saturation value. This strip is also lined with a strip of ferromagnetic material with a coercive field (magnetic “hardness”). Detection is achieved by sensing harmonics and sum or difference signals generated by the non-linear magnetic response of the material under a mixture of low-frequency (in the 10 Hz to 1000 Hz range) magnetic fields.
When the ferromagnetic material is magnetized, it biases the amorphous metal strip into saturation, where it no longer produces harmonics. The tags are activated by demagnetization and deactivated with magnetization.
The identifier associated with the receptacle is preferably a discreet identifier which is assigned to the receptacle 100. The identifier information is stored on a database typically located at the external site 300, and electronically joined with an account to which the receptacle 100 belongs. In other words, account information is housed on a database located at the external site 300. Each account has one or more receptacle identifiers associated with it, and the database carries with it information typical to the management of any business account, for example, special instructions, accounts receivable, last receipt, last invoice, amount in arrears, days since last payment, historical account information, contact information, owner, etc.
As illustrated in
As set forth above, this aspect of the invention directly results in cleaner streets and alleys. The invention will eliminate or reduce trash overages, under size containers, poor container maintenance condition, e.g. no lid. Permits and citations will force compliance. Users can specify correct container size, schedule additional pick-ups. Service may be halted due to lack of payment or by schedule.
Information regarding each permit/receptacle identifier, the account associated therewith, and the entity responsible for the account/permit/receptacle is stored on a managed database. The database may include other information such as hauler name, permit number and container asset number (human readable sticker and RFID tag). Use and access of the database is explained in more detail below.
The RFID tags can be read by inspectors having mobile and/or handheld computers 400. Citations may be issued immediately via printer on the handheld 400 and/or mailed with back-up violation data. Inspectors and other municipal employees use mobile handheld RFID readers with cameras to read tags and report violations. Citations can be issued and wireless transmission of data achieved through the handhelds 400.
This aspect of the invention requires haulers or receptacle owners to purchase annual container permits. The issued permit includes a means for transmitting, such as an RFID container tag. Revenue to the municipality is generated by an enforcement program.
Further, a container registration fee includes RFID tagging. The RFID tag information is linked to customer and hauler information in the database.

Each of the vehicles 200a-d includes a waste bin 202 located above a baseline upon which the vehicle 200a-d is supported, generally the ground. The waste bin 202 includes a chamber 204 and an emptying site 206. The refuse within the receptacles 100 is loaded into the chamber 204 via the emptying site 206. One of ordinary skill in the art of waste hauling would readily understand this method of refuse handling without further description as it is the standard procedure employed in the art.
The vehicles 200a-d are further outfitted with at least one receiver 208a, in most cases a plurality of receivers 208a,b and preferably two. The receivers 208a,b may be sensors, transducers, or antennae, or any combination thereof. As illustrated in
The locations chosen for the receivers 208a,b are extremely important because the receivers 208a,b are used for several different purposes, including for possible tracking of the receptacle 100 as it is transferred from position-to-position relative to the vehicle 200a-d by a means for transferring the receptacle 212, which may be automated systems known in the art, as shown in
The preferred location of the first receiver 208a on a front loading vehicle 200a, illustrated in
The preferred location for the first receiver 208a on a side loading vehicle 200b, illustrated in
The preferred location of the first receiver 208a on a rear loading vehicle 200c, illustrated in
The preferred location of the first receiver 208a on a roll-off vehicle 200d, illustrate in
The vehicles 200a-d also include a second receiver 208b located at a position where reception of the signal from the transmitter means 102 can be promoted either at the instant of receptacle unloading or just prior or just subsequent to receptacle unloading. Accordingly, this second location is typically adjacent the emptying site 206 to the chamber 204 and in alignment with the first receiver. The phrases “in alignment with the first receiver 208a,” “aligned with the first receiver 208a,” and the like are intended to include a position wherein a path of the receptacle and the means for transmitting 102 taken from the first position at the first receiver 208a to a second position at the second receiver 208b, as determined by the means for transferring the receptacle 212 included on the vehicles 200a-c, naturally brings the means for transmitting 102 to a location where the second receiver 208b can receive the signal from the means for transmitting 102, i.e. into a range of the second receiver 208b where reception is achieved.

As shown in the block diagram of
The external site 300 may include a server 302 in communication with computer 304 and a database 306, typically on the computer 304. Of course, the server 300 is not required to be at the same physical site as the computer 304, nor is it required for the database 306 to be stored on a computer separate from the server 302. The block diagram is merely an example of a possible layout. The only requirement for the external site 300 is the database 306 and a means for communication between the vehicles and database 306.
Now, as illustrated in flowcharts of

Next, the communication link sends a signal, either pass though or new, to the external site which receives the signal. The identity of the receptacle 100 is checked against an account database 306 to verify that the receptacle 100 should be emptied into the vehicle 200. A signal is generated indicating the account status associated with the receptacle identifier.
If the account is in good standing (pass condition), the controller 214 for the means for transferring the receptacle 212 is automatically activated either by a module or routine on the on-board computer or on the external computer 304. The means for transferring the receptacle 212 transports the receptacle 100 to the emptying site 20 where the transmitter means 102 is within reception range of the second receiver 208b. The transmitter means 102 sends a signal carrying discreet receptacle identifier information to the receiver 208b. The receiver 208b either passes the signal directly to the on-board communication link, preferably a module of the on-board computer 216, or generates a new signal based on the signal received from the means for transmitting, but still including some type of receptacle identifier. The triggered or pass through signal from the second receiver 208b represents an event. The event is preferably the emptying of the receptacle 100 into the vehicle bin 202. This event is recorded on the database 306 at the external site 300 and associated with the receptacle account.
If the account is not in good standing (fail condition), the controller 214 is not activated, a signal carrying an alarm or warning is transmitted to the vehicle 200. The account status can also be displayed on the on-board graphic interface 218. As a result, the transfer means 212 is not activated, and the receptacle 100 is not emptied into the vehicle bin 202. However, if for some reason, such as immediate, on-the-spot payment of an invoice by a customer, the vehicle personnel are inclined to empty the receptacle 100, vehicle personnel may override the alert and manually engage/energize the transfer means 212. In this case, as illustrated on the right hand side of

For example, the external site 300 receives a first signal carrying a receptacle identifier from the vehicle 200. This first signal is associated with the receptacle 100 being located at the first position. The first signal originates with, though is not necessarily identical to, the signal received from the transmitter means 102 at the first receiver 208a. A module at the external site 300, preferably on the computer 304, compares the data carried by the signal against account information on the database 306 to determine an account status associated with the receptacle identifier. The result of the comparison, i.e. the account status, is transmitted from the external site 300 back to the vehicle.
Further, the external site 300 receives a second signal from the vehicle 200. This second signal is associated with the receptacle 100 being located at the second position. The second signal originates with, though is not necessarily identical to, the signal received from the transmitter means 102 at second receiver 208b. A module at the external site 300, preferably on the computer 304, compares the data carried by the signal against account information on the database 306 and records an event, the emptying of the receptacle 100, in connection with the receptacle 100.
While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention, and the scope of protection is only limited by the scope of the accompanying Claims.
