The present invention relates generally to a system for handling livestock and more particularly to a system, means, device or apparatus to affect the efficient handling of livestock in the unloading of same from a transport vehicle to a farm site or processing plant.
It will be understood and appreciated that as the foregoing description of the present invention may be explained as it pertains to the handling of poultry, this description in no way shall be indicative of the limiting of “livestock” thereto.
Commercial poultry, such as turkeys, chickens, guineas, peafowl, ostriches, ducks, geese, swans and pigeons, have been one of man's main staples of protein throughout history. For centuries poultry was raised and processed on the farm and locally delivered to those who desired such fresh poultry. But as the population migrated to towns and cities, delivery of fresh poultry became increasingly difficult while the demand for processed poultry increased dramatically. In response to this need, fresh processed poultry now had to be transported to the markets located in these cities.
The poultry was customarily gathered manually at poultry houses, boxed or crated with numerous birds per crate, manually loaded aboard an open truck or van, and transported. The problems created by such a procedure were both numerous and significant. The manual handling of the poultry not only created a materially high cost involved in raising the poultry and preparing them for market, but it also created certain physical dangers to both the poultry as well as the workmen.
For example, during hand catching and subsequent handling of poultry, some birds are bruised, injured, or even killed due to a violent reaction of the birds or the unintentional rough handling by the workmen. Additionally, fowl inevitably beat their wings in an effort to escape upon capture, this would frequently result in a bird striking the handler with sufficient force to cause physical injury.
As technology was developed for the processing and safe storage of poultry, small processing plants developed and the manual loading and unloading of crates or coops began to improve. One of the first significant improvements, particularly in the turkey industry, was to create coops or crates which were permanently attached to a trailer or truck bed. These trucks contain large numbers of individual coops attached on the truck body. The coops having doors opening outward and being arranged in horizontal rows and vertical tiers. These coops or compartments typically having a permanent middle portion partition, and as such require loading from both sides of the truck. Not only is this time consuming, but loading from both sides also requires the trailer to turn around with all of its weight on one side thus causing an unsafe situation to driver, livestock, machinery and trailer.
The usual method of loading the poultry was to catch the animals individually and then lift and carry them to the coops while using makeshift platforms to reach the higher coops or to hand the birds to other workmen who are clinging to or standing on supports attached to the sides of the truck. The adult male turkey may weigh in excess of forty pounds, thus, any mishandling thereof causes a high incident of injuries to workers and animals alike, not to mention the considerable time requirements needed to accomplish the loading/unloading of a complete truck. The past thirty years have seen various conveyor belt apparatus designs to convey the poultry to the different heights of the vertical tier of coops. However, at the exit end of the conveyor belt, personnel still manually stuffed turkeys into compartments or coops. Thus, while such apparatus eliminated the laborious task of lifting animals to the different heights of coops in the vertical tier, the arduous task of stuffing the live poultry continued.
In light of preceding problems, there has been an effort in the art to develop a method of loading poultry for transport with a minimal amount of manual labor. For example, U.S. Pat. No. 5,902,089, issued May 11, 1999 describes a poultry loading apparatus for transporting poultry from a confinement area such as a poultry house to a transport vehicle to allow transport of poultry from farm-to-farm or from farm-to-processing plant. This is accomplished through the use of a base and a sectional mainframe defining a transport conveyance system. A section of the mainframe is pivotably attached to another section which is pivotably attached to the base. The apparatus further utilizes a control system for its overall leveling and pivotal height adjustments, as well as the extending/retracting capabilities of its conveyance.
Such a conveyance system certainly provides for an apparatus and system for loading poultry for transport that minimizes labor and costs while maximizing efficiency. However, when the fully loaded vehicle stops at its desired location, it must be unloaded. Although this conveyance apparatus is certainly capable of such unloading, it may be difficult to maneuver this apparatus within the typically less spacious area of a processing plant. In any event, the unloading process during the past two generations has not changed. The animals are manually grabbed and pulled out of the crates or coops and inverted on a shackle. Consequently, the animals are under high stress and typically react violently, thereby causing possible injury to themselves and/or the workers/employees. Thus, there exists a need for a poultry unloading apparatus and system that reduces labor costs and damaged product while increasing safety and efficiency.
Today, the poultry business is a multi-billion dollar industry. Large companies dominate the production, slaughter and marketing of products. Since poultry companies are now fewer in number, they therefore demand large quantities of animals daily for processing. In fact, enormous numbers of poultry are transferred daily from production facilities to the slaughter plant or to different production facilities en route to the slaughter plant.
With the advance of science and particularly the art of genetics the animals are becoming larger earlier in life. In fact, the average weight of a male turkey (for example) may exceed fifty pounds within the next five years. This requires a high demand for automation by the processors, and fundamental changes are now occurring as the production and processing consolidates. There will be more focus on creating, managing and tracking supply chains from the farm to the retail shelf that can elevate quality, consistency and demand responsiveness to previously unforeseen levels. At the same time, there is growing evidence that retailers (and ultimately consumers) are becoming increasingly proactive about the processes that generate the meat they are purchasing. More specifically, while all consumers should be concerned with food safety, some consumers have become increasingly proactive with respect to the welfare of the animals they are consuming.
In view of the aforementioned needs and the shortcomings of the prior art, it is therefore an object of the present invention to provide a system that overcomes the deficiencies of the current practices whereby an apparatus and system is provided for unloading livestock for transport with a minimum amount of labor and with maximum efficiency at a minimum cost.
It is another object of the present invention to provide a livestock unloading system which maximizes efficiency and decreases damage to the animals during processing. It is another object of the present invention to provide a livestock unloading system which minimizes labor costs by reducing the number of employees as well as the turnover rate of employees.
It is yet another object of the present invention to provide a livestock unloading system whereby the manual and perhaps rough handling of the livestock is eliminated thereby improving overall animal quality by reducing animal stress and minimizing any damages sustained to the livestock. This reduction of stress decreases fecal contamination which in turn increases food safety.
Still another object of the present invention is to provide a user friendly livestock unloading apparatus that may be operated effectively by very few personnel.
Another object of the present invention is to provide an answer to the animal welfare conscious public regarding the handling of livestock.
Still another object of the present invention is to provide an unloading system that integrates tracking and/or data collection systems for the coop modules, trailers, transport vehicles, coop modules, coop containers and individual livestock.
Yet another object of the present invention is to provide a livestock tracking system and method that identifies livestock and collects data thereon such that the journey of the livestock from farm to consumer is transparent.
These and other objects, features and advantages of the present invention will be clearly understood through a consideration of the following detailed description.
According to the present invention there is provided a livestock data collecting system including a plurality of successive conveyors for receiving livestock. Each conveyor having an associated variable speed such that the group of livestock is eventually thinned out and individual livestock are separated by gapped spaces to enable individual data collection.
A system for tracking livestock from farm to consumer is further provided wherein a first set of individual livestock data from uniquely identified containers is stored. A second set of data is collected upon unloading of the container and is compared against the first set to provide reports on the livestock.
A method for tracking livestock from farm to the consumer is also provided. The method includes the steps of loading a group of livestock, separating the group into individuals, collecting data on the individuals, loading the individuals into uniquely identifiable containers, transporting the containers, unloading the containers and collecting data. The comparison of data is then used to generate reports on the livestock.
The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The invention, together with the further objects and advantages thereof, may best be understood by reference to the following description taken in conjunction with the accompanying drawings, in the several figures of which like reference numerals identify like elements, and in which:
The present invention provides for a system of unloading livestock from a transport vehicle to a farm site or processing plant. As the livestock first require to be loaded upon the vehicle,
The present invention includes, among other things, a uniquely designed transport vehicle.
Each coop module 16 is secured on the coop trailer 12 via attachment members 13, which will be discussed in further detail below. The coop module 16 is secured onto the trailer in a semi-secure manner to allow the module to move slightly during transport. This movement helps to deter stress cracks on the module frame.
A standard coop trailer typically includes one hundred forty four coops per trailer, with each coop having a volume of about 16 cubic feet. This standard trailer requires the loading of one side of the trailer and turning the trailer around to load the opposite side. As such, the manual unloading process for turkeys entails personnel on both sides of the coop trailer physically grabbing/pulling and inverting the turkey to position its legs into a shackle. By contrast, the present system includes a coop trailer 12 with coops 14 having a volume of about 64 cubic feet. The swinging partition 18 of this trailer 12 allows the extension of the primary indexes of the unloading apparatus through the length of the coop (width of the transport vehicle), thus allowing the trailer to be completely unloaded and loaded from one side. This primary index extension arrangement is described in further detail in co-pending U.S. patent application Ser. No. 10/044,675. With fewer and larger coops, loading/unloading speeds can match processing plants line speed; and biosecurity and cleaning of coop modules are easier and require less time.
More particularly, an embodiment of the coop module 16 design of the present invention is illustrated in
The coop floor support, not shown, is currently a checkered pattern flat iron structure, while the coop floor is thin durable and washable plastic compound. The floor is slid into place from the side and held in place by metal tabs 28 or other means of securement. The floor may be more securely held atop the structure via screws in its middle, or rubber mounts attached above to allow the floor to flex to a minimal bend, particularly during the updraft wind pressure caused during transport without the livestock.
As shown in
An additional mesh 30 is used for the sides of the coop 14. This mesh 30 is stationary and welded to the tubular steel frame 32 of the module. The size of the mesh is such that it allows free air movement yet small enough where animal parts cannot become entangled during transport and/or loading/unloading. This mesh or the doors may be enclosed by wooden or plastic panels or a flexible curtain (not shown) during inclement weather. These panels or curtains may be stored under the trailer as previously shown in
As shown in
The partition 18 is generally situated in the middle of the coop and its structure serves to prevent the animal from shifting while inside the coop. More specifically, the partition 18 is situated such that it does not touch the floor 39 of the coop 14. The top portion of the partition 18 further includes a semicircular top portion or the like 38 and is further situated such that the semi-circular top portion 38 generally engages the ceiling 40 of the coop 14. This arrangement prevents the animals from shifting while inside the coop while further stopping them from entangling their limbs when the partition raises or lowers.
Now turning to
As shown in
As shown in
With the above mentioned lifting device 46, each coop module 16 may be removed from a trailer, moved, and placed near a base unloader unit 70. As shown in
The base unloader 73 of the present embodiment unloads the livestock much like the unloader disclosed in applicant's recently allowed U.S. patent application Ser. No. 10/044,675, hereby incorporated herein by reference. More particularly, when the coop module 16 is positioned adjacent the unloader 73, at least one primary index 72 extends into a coop. It is important to note that the primary index is fully extendable into the coop and therefore enables the unloading of a coop module 16 from a single side without the need to re-position the coop module to unload from the other side. Once a coop is emptied of livestock, the primary index can be repositioned to empty the remaining column of coops. Once a full column of coops is emptied of livestock, the coop module may be repositioned on the conveyor 80 to empty the next column. Alternatively, the base unloader 73 may have multiple indexes and accordingly be capable of unloading more than one column and coop at a time.
Once the livestock leaves the coop module 16, they can be conveyed to an unloading station and/or a preshackle stunner before they are moved on to final processing. At the unloading station, individual livestock information may be gathered (i.e. weight, DOA, etc.) for later further analysis. The preshackle stunner may be of the typical CO2/O2, nitrogen, electric, and/or other means. Once these steps are complete, the livestock is ready for further animal processing.
Opposite the primary index 72 is a movable platform 76 to facilitate in the unloading process. By raising and lowering of this platform 76, an operator may easily access each coop. Accordingly, an operator helper may release a lodged animal and may further access each coop via opening the coop door to assist in the washing and disinfecting of the coop module. In addition, the operator can manually raise the partition 18 by inserting a hook and pulling the top 38 of the partition and temporarily lock the middle partition in the up position during the unloading process. In any event, during this process, the coop module 16 is further positioned on a coop module transfer conveyor 78. The section of conveyor 80 associated with the base unloader 74 and the coop module 16 situated thereon are raised and lowered, or otherwise moved away and toward the primary index 72 via a hoist 82, in order to facilitate the aforementioned unloading process.
The conveyor 80 has predetermined stops for the coop module to stop at a position for the primary index 72 to extend cleanly the length of the container for each column of the coop module. In addition, as base unloader units 70 are utilize, predetermined stops are designed for all columns of the coop module in case one or more base unloading units 70 primary indexes malfunctions. Synchronization component 86 insures a true vertical and descending motion of the coop module in relation to the base unloader units 70 primary indexes 72. This will allow for the primary index 72 to slide evenly over the coop floor 39 and preventing feathers or toes from being pinched. Means other than hydraulic cylinders could raise the conveyor 80 and other means could be implemented to maintain the conveyor vertically true to the base unloader unit primary indexes.
After unloading and processing, the coop module is conveyed to another section of the conveyor 84 for washing or disinfecting. The clean coop module may further be transferred back to a trailer via yet a lifting device similar to that described above.
The flow diagram, or value stream map, of
Depending upon plant parameters, coop modules are removed from the trailer and the trailer may be stored at an optional trailer park 120 until such time as it is called to load preparation 138. In any event, the modules are moved to a staging area 122 before the overhead crane picks them up at module sequencing 124 and delivers them to the chain conveyor 126.
The unloading station 128 removes the livestock from the modules as described above and delivers the modules to the wash/disinfect area 130 and the livestock to the preshackle stunner area 132 and on to animal processing 134. After the modules are washed and disinfected at 130, they are stored 136 and perhaps serviced/repaired before they are attached back to a trailer at load preparation 138.
The present invention has also been designed for ease in tracking and data collection, and in particular takes into account the numerous advantages of radio frequency identification (RFID), for example. RFID is an example of a system that can be used by the present invention for tagging and identifying both static sites/objects and mobile objects (i.e. live production sites, unloading facilities, loading sites, coop containers, coop modules, coop trailers, semi-trailers, livestock, loaders and unloaders) so that they can be labeled and tracked as they move from place to place. At the loading station 108, for example, such personal animal information like weight and individual temperature, as well as other more general information like location, start time, finish time, temperature, humidity, barometric pressure, number of animals, etc. can be documented with the use of a personal digital assistant or other electronic recording/transmitting means or possibly non-electric means. Similarly, at the unloading station 128, the same information as well as other information (i.e. DOAs, body temperature and individual weight) can be documented. Theses types of tracking systems can take into account the possibility of future improvement of data gathering within the livestock itself that could collect/analyze information (i.e. hormone and enzyme levels, antibodies, specific animal traits, etc.).
While the present invention will be shown and described through the use of RFID, it will be understood that other forms of identification has also been contemplated, and the invention is therefore not limited to the use of RFID. In any event, RFID systems are typically comprised of a series of RFID tags which upon request will provide specific information to an RFID reader. RFID tags come in three varieties: passive, active, and semi-passive. The primary difference between the three types is the RFID tag power supply. The passive RFID tag has no internal power supply, and operates by using power taken from the RFID reader to provide sufficient energy to transmit the information stored in the passive RFID tag. The information that is transmitted is stored in a circuit within the passive RFID tag and is transmitted from an antenna on the passive RFID tag. The information stored in the tag may be as simple as an identification code to identify the object being tracked, or the information may be any non-volatile data.
Active RFID tags have an internal power supply for powering internal circuitry and broadcasting the RFID signal from the tag itself. Active RFID tags can broadcast a stronger RF signal, as opposed to passive RFID tags, to be read by the RFID reader. The ability to broadcast a stronger signal is desirable in locations that would be considered harsh RF environments. An active RFID tag may also have sensors to take data from the item being tracked by the RFID system. Furthermore, the active RFID tag will be able to transmit information stored in the circuitry of the tag, such as an identification code, and any data both volatile and non-volatile.
Semi-passive RFID tags have an internal power supply which does not power the transmission from the antenna to the reader. The internal power supply only powers the circuitry that receives the signal from the RFID reader, the circuitry that stores data, and the sensor circuitry that measures data from the item being tracked by the RFID system. Much like the passive RFID tag the semi-passive RFID tag can transmit information such as an identification code and non-volatile data; however, the semi-passive RFID tag can also transmit volatile data as well because of the power supply on the tag. The only real drawback of the semi-passive RFID tag from the active RFID tag is the broadcast signal from the semi-passive RFID tag is a much weaker signal and will not perform as well in harsh RF environments.
An RFID reader is a device that is usually configured in some kind of loading/unloading or tracking system to read information from RFID tags. The RFID reader will be composed of circuitry and an antenna capable of communicating with an RFID tag. Information is gathered from RFID tags communicating with the RFID reader and stored and processed by the larger system used in the particular RFID system.
A further embodiment of this invention would use a variation of the RFID system, described above, to track and provide specific information about the trailers, coop modules, coop containers and individual animals being transported. From
Furthermore, it is envisioned that the livestock can be fixed with an RFID tag as well. These tags could possibly be inserted below the skin of the animal at birth or attached to the outer part of the animal during the live production period. These tags are then removed during processing. At the loading stage 108, the livestock will be measured, and the data will be associated with or without the specific RFID tag identifying the particular animal. Such measurements would at least consist of the weight of the particular animal. Also, the RFID tag on the livestock will be tracked in the system to tell what particular coop container the animal is in, the coop module the animal is in, what trailer the animal was transported on, what barn the animal came from, and what flock the animal was part of.
At the unloading station 128, the RFID reader will see what specific coop containers and coop modules are being unloaded and detect what livestock is present in the module. At this point, the coop module with the livestock still contained within can be weighed. From this measurement average shrinkage can be calculated by the system. Also, the time at which the trailer/coop module arrived at its destination would be logged thus allowing total transportation time to be associated with a particular animal. Also, as the livestock is unloaded, further measurements may be taken; these measurements will be correlated to earlier measurements done at the loading stage 108. For example, the correlation will enable the system to identify how much the specific animal shrank during the transportation. Also, animals that are dead on arrival (DOA) will be detected and located in a particular coop or coops per coop module at the unloading stage 128. The system will associate the DOAs with their specific identification in the RFID system.
All the information tracked with the livestock will be stored as data associated with a particular animal. If information is ever needed on a specific animal because of a complaint or a food safety issue, the individual animal data will be readily accessible. The information stored could consist of what barn the animal was raised in, what flock the animal was part of, what trailer the animal was transported in, what the weather conditions were during transportation, the livestock density of the particular coop module that transported that animal, how long the livestock was in transportation, and how many DOAs were detected in the transportation of that particular trailer or coop module. All of the above information would be extremely helpful if a recall of particular livestock was needed. Another novel use this information of live animal well-being would be relayed to the consumer where consumer purchases via retailers would have objective measurements to determine how and what conditions the animal was produced. A retailer and/or wholesaler can accordingly design a procedure consisting of any parameters to use the individual and group data as a strong selling point to an ever concerned animal conscious consumer. Through use of the present invention, synchronized with an implant tracking/data collecting system, management personnel, who until now have had no hands on knowledge of the process and procedure from farm to consumer, can now, with their own first hand knowledge, make sure their company not only meets all standards but they will also have the evidence to assure their customers and the end consumers.
More particularly, the storage pen 204 is where the livestock is herded prior to being funneled into the feeder conveyor 206. Livestock that cannot be herded, chickens for example, utilize a special apparatus that picks up the live chickens from the barn floor and deposits the live chickens on main frame conveyor 212. Accordingly, conveyors 206, 208, 210 would be eliminated for chicken use. In any event, at this point the livestock is excessively crowded as they are funneled into the feeder conveyor 206. The subsequent series of conveyors (e.g. 208, 210, 212 and 214) will redistribute/reposition the livestock in order to uniformly disperse the animals into at least two singulation lanes for data collection and to uniformly fill the individual coop container 201 within the coop module 202. The number of singulation lanes is determined by the size and density of the livestock being transported. Smaller livestock (e.g. chickens) will result in more singulation lanes, and larger livestock (e.g. turkeys, swine and cattle) will result in fewer (if not one) singulation lanes.
In the present embodiment, feeder conveyor 206, pre-loader conveyor 1208, pre-loader conveyor 2210, main frame conveyor 1212, main frame conveyor 2214, head section conveyor 1216, head section conveyor 2218, and the reciprocating conveyor 220, each having their own speed controller, which may be all controlled by a processor or computer, although it is possible to control by manual means. The computer controls the speed of the successive conveyors so as to accomplish the singulation and distribution of the livestock in such a manner where individual data could be collected. In addition to the speed of the conveyors, singulation is aided by a deflection device 222, located in the head section conveyor 1216, which helps to push the livestock into a specific singulation lane. Alternatively, deflection mechanisms could be installed in different locations within the conveyor chambers to facilitate the positioning of the animals. The number of deflection devices 222 present can be altered for the specific size of the livestock being loaded.
As can be seen in
Data pertaining to the animal position is collected as the livestock is being transported down the series of conveyors. More particularly, the data is gathered from a battery of strategically placed sensors along each conveyor path to determine the group density at that particular point. This data will enable the effective speed control of each conveyor so as to gradually thin out the crowded group of livestock and attain singulation and the ability to collect data on individual livestock.
In
The scale and counter 238 weighs and counts the livestock as they are loaded into the individual coop container 201 in the coop module 202. This arrangement allows the operators to take live weights of all individual animals while the line is moving and without interrupting animal flow. The livestock is counted in order to determine how many animals are left to load into the individual coop container 201 in a coop module 202. The individual animal weight is associated with the livestock either by individual identification or by keeping track of the animals' location within the coop container 201. Furthermore, the loaded individual coop container 201 is weighed as well as the loaded coop module 202 is weighed, and the data is stored to use later in calculating shrinkage once the coop module 202 has arrived at the unloading facility.
In order to keep track of the livestock during transport the individual coop container 201 is composed of two zones. The two zones within each coop container in a coop module 202 are zone A 232 and zone B 234. Singulation lane 1242 and singulation lane 2240 load the livestock into the individual coop container 201 in the manner depicted in
The operators' screen also provides a readout showing the diagnostics of the overall system. The system in the preferred embodiment is an electrically controlled hydraulic system. Therefore, indicators such as the overall temperature of the system and the oil temperature amongst others will be displayed on the operator's screen.
The operator's screen can also be tied into the RFID system. The various RFID tags will indicate important information about the condition of the equipment being used. The operator's screen will let the operator know how densely packed the livestock should be for transportation. Furthermore, through the RFID system the operator's screen could indicate exactly what animals are being loaded into a specific coop container and coop module and record that information for later use.
After the coop module 202 arrives at the unloading station shown in
In
An unloader computer, similar to the operator's computer in
While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made therein without departing from the invention in its broader aspects, and, therefore, the aim in the appended claims is to cover all such changes and modifications that fall within the true spirit and scope of the invention.
