The present invention relates to a system and method for monitoring utensils in slaughterhouses, and utensils, wherein the utensils have a type of identification for monitoring, wherein specific data about said utensils is recorded in order to obtain traffic control and usage data of the utensils.
The market for meat production is promising and durable, but working on a slaughterhouse is a risky activity. Slaughterhouse workers are often cut off due to work-related diseases (WMSD) and repetitive strain injuries (RSI). In addition, slaughterhouse workers have higher chances of trauma (including cuts with saws and knives) of the abdomen, shoulder and arm, four times more muscle and tendon inflammation, and up to seven times more wrist injuries due to ergonomic problems.
In order to change this scenario, many labor laws are created in order to address the usability aspects of knifes and tools with ergonomic aspects such as handle, comfort, weight, ease of use, analysis of movements and activities, as well as constant sharpening and control and replacement systems for sharp knives. Such focus, for example, on the sharpening of knives aims at eliminating a common practice in slaughterhouses: the provision of shortened knives to increase the useful life of these products, but with negative consequences in terms of long-term ergonomic problems for workers.
In order to comply the process of sharpening knives to labor laws, slaughterhouses need innovations in their registration and control systems for knife sharpening. In this sense, the possibility of important technological innovations arises.
An example of a system that makes this interconnection is in U.S. Pat. No. 6,867,598 that relates to a system for identification and tracking of utensils in slaughterhouses for deboning purposes. The system describes that the utensils can only be a knife or a glove, and their main purpose is to control prerequisites (primarily sanitizing) by mapping the locations and periods the knife passes and comparing with a previously established protocol. In addition, the document does not mention many types of data that can be collected and aim more the theft control of utensils.
WO2005108183 discloses a deboning or chopping knife, comprising a blade and a handle, wherein a transponder, comprising a information storing transceiver device and unit controller, is inserted into the knife handle. The document focuses on the knife communication via RFID with any reading device, storing the information on at least one computer in the slaughterhouse where the readings are being performed. In addition, the system allows recording of multiple information, including when sanitizing occurs and when sharpening occurs, but according to the document, the recording of data is not automatic and the invention aims only to control whether the operational requirements are being followed (previously defined protocol), that is to say, whether the knife is sharpened, if sanitization is performed, who is responsible for the knife, if there were no knife disappearing in the process, etc.
WO2009146681 discloses a method for detecting and/or identifying a hand tool. The document looks at aspects of user controls and responsibility for knife or other utensils, especially to prevent knife theft and sabotage (such as an employee purposely putting the knife in grinders, destroying machines or causing any damage to the slaughterhouse).
It is an objective of the present invention to provide a system and method for monitoring utensils for slaughterhouses capable of including recording of utensil data shareable with the various slaughterhouse plants and the knife factory itself.
It is also an objective of the present invention to maintain the record data of the utensils in a cloud.
It is yet an objective of the present invention to collect satisfaction data from utensil users.
A further objective of the present invention is to be able to retain control data of workers movement and work in order to effectively prevent repetitive strain injuries and thus provide a form of control and monitoring for labor laws.
Another object of the present invention is to provide a system and method of integrating collected data from all the utensil data capture locations with the slaughterhouse and the utensil factory in order to create a data network.
It is a further an object of the present invention to provide a utensil with a readable medium that assists in monitoring it.

The present invention encompasses that each individual utensil 100 of each user working in the slaughterhouse comprises the at least one readable medium 110.
In a further embodiment, all slaughterhouse utensils 100 comprise at least one readable medium 110 and the slaughterhouse selects which reading devices 210, 220, 230, 240, 250, 260, 270, 280 are to collect the data of the utensils 100.
The present invention comprises a combination of possibilities of readable medium in utensils 100, wherein if it is not of interesting to the slaughterhouse, a particular utensil will not comprise the readable medium. In addition, reading devices 210, 220, 230, 240, 250, 260, 270, 280 should also comprise given reading means for a given readable medium 110 and, if the slaughterhouse is interested, it should read the at least one readable medium of the given utensil 100.
The at least one readable medium 110 is at least one of: a bar code, a numerical code, a radio frequency device, a Bluetooth device, an infrared device and a QRCOD.
In alternative embodiments, the at least one utensil 100 comprises more than one readable medium 110, preferably at least two of: a bar code, a radiofrequency device, a Bluetooth device and an infrared device. In such embodiments, each reading device 210, 220, 230, 240, 250, 260, 270, 280 may collect different data from different readable media 110.
In one example of the present invention, the utensil 100 comprises only one readable medium 110, the readable medium 110 preferably being a radiofrequency device. Each time the utensil 100 passes a reading distance of a reading device 210, 220, 230, 240, 250, 260, 270, 280, it will collect the data of the utensil 100.
In another example of the alternative embodiment of the present invention, the utensil 100 comprises a readable medium 110, preferably a radiofrequency device, and another readable medium such as, for example, a bar code. Each reading device 210, 220, 230, 240, 250, 260, 270, 280 will have its reading means suitable for at least one of the two readable medium 110. Thus, a sharpening device 210 may comprise reading means that collect data from the radio frequency device signal and reading means to read a bar code from the utensil 100 to collect different data from the reading means of the radio frequency device. In addition, in order to exemplify the different combinations of quantities and types of readable mediums 110 and reading devices 210, 220, 230, 240, 250, 260, 270, 280 which collect data from each of the readable mediums 110 types, the same example of the previous alternative embodiment, a sanitizing and sterilizing device 220 comprises only means for reading the radio frequency device, and can thus only collect data relating to that readable medium.
Each slaughterhouse should define which readable medium to use, where and which reading device should collect what data pertaining to which utensil, in the way that best suits the slaughterhouse.
Through the present invention, data collected from at least one reading device 210, 220, 230, 240, 250, 260, 270, 280 can be stored in one of: a hardware of each reading device 210, 220, 230, 240, 250, 260, 270, 280, a central hardware that is interconnected between each of the at least one reading device and directly into a cloud, wherein the data stored in the cloud can be sent directly through the reading devices 210, 220, 230, 240, 250, 260, 270, 280 or via a central sending device which receives data from at least one reading device 210, 220, 230, 240, 250, 260, 270, 280 and sends these data for cloud storage.
Through this system, the present invention is able to interact with all data collected in order to provide usability improvement for the user (operators), the slaughterhouse and the utensil factory. The present invention enables the interaction between the utensil 100 manufacturer with the slaughterhouse, the user, the activity and maintenance of the utensil (sharpening, sanitizing and any other activity performed on the utensil). As a result, the user evaluates the utensil and the data collected by the reading devices 210, 220, 230, 240, 250, 260, 270, 280.
Thus, all the data collected aim to identify the factors that affect the usability of the utensil 100, such as the human factor involved, the activity exerted, the environment of use of the utensil and the conditions of manufacture of the utensil 100. The usability result of the utensil is measured by satisfaction of the interaction of these factors, since it records the user's evaluation, that is, momentary satisfaction with the used utensil. The usability of the utensil 100 is always something subjective and momentary being influenced by the interaction of all the data collected by the present invention, sharpening data, sanitizing data, lifespan data, the timing and reason for disposal, and the design of the product itself suitable to the user and activity. Change in any variable may be significant in the final evaluation of the utensil.
Additionally, in one embodiment of the invention, some data is inserted into the system to better evaluate all of the usability variables of the utensils 100. The data may refer to the information of the slaughterhouse or utensil 100.
The data to be entered relating to the information of the slaughterhouse is at least one of: the gender of the user of the utensil 100, utility of the utensil 100, such as, for example, whether the utensil is being used for deboning or trim, the type of meat to be to be deboned, whether the utensil is used in a slaughter area or chopping area, i.e., against cold meat or hot meat, among others.
The data to be entered concerning the slaughterhouse information can be linked to the utensils by at least one of: the slaughterhouse itself, when it receives the utensils 100, the utensil factory and the user. The user or slaughterhouse can link the information when the utensil is first received. The user may also link this information at the beginning of his/her shift or when it reaches some reading device 210, 220, 230, 240, 250, 260, 270, 280, preferably the workstation 270.
The data linked to the utensil 100 are at least one of: blade design, steel type, handle type, user-performed activity. Such data linked to the utensil 100 may also be linked by the utensil factory, the slaughterhouse or the user. The information may be linked by the factory before going to the slaughterhouse, when the slaughterhouse receives the utensil for the first time, through the user at the beginning of the shift or when the user arrives at some reading device 210, 220, 230, 240, 250, 260, 270, 280, preferably the workstation 270.
In
In step 1000, at least one data relating to at least one utensil 100 is collected through at least one reading device 210, 220, 230, 240, 250, 260, 270, 280; in step 2000, the data collected on at least one of a hardware and a cloud database is stored; and in step 3000 the data is available for query and monitoring of the at least one utensil 100.
The method may further comprise a step of: emitting 4000 at least one of an audible alert and a visual alert in at least one of the situations: when the reading means of a passage warning device 250 identifies a utensil 100 that should not move through the passage warning device 250 and when the workstation device 270 identifies that the utensil needs at least one of the maintenance of: sharpening, sanitizing and blade realignment when a certain time of the last maintenance has elapsed.
To assist in the utensil monitoring method, at least one of the following additional data is entered into the system: blade design, steel type, handle type, user performed activity.
The present invention provides a system and method of monitoring utensils and utensils that can collect multiple data from a slaughterhouse both related to the work of utensil users and the physical aspects of the utensil itself in order to create a database that can be studied both by the slaughterhouse and by the utensil factory, allowing both the slaughterhouse and the utensil factory to improve their products, services and quality, as well as to provide data to control the functional well-being of the utensil user and to avoid undesirable transit of utensils in and out of the slaughterhouse rooms.
Over time, new data reading devices (not mentioned herein) or utensils may appear, in which influence user satisfaction, utensil conditions and maintenance, and which may be included in the system of the present invention.
