    [0001] SCALE AND WEIGHING SYSTEM FOR LIVESTOCK
    [0002]
    [0003] Object of the invention
    [0004] The present invention relates to a scale and a weighing system for livestock that are aimed at providing precise control of the weight of each of the animals in real time in the bait phase; where the weight of each animal can be controlled every time it approaches to feed at a feeder. The system of the invention allows the animal to be identified while it is eating, and in this way the weights can be controlled and stored every time the animal approaches to eat. It should be noted that the weighing system allows the animal to be weighed by supporting only its front legs on the scale, and by means of a processor, such as a CPU integrated in said scale, it allows to know the history of the different controlled weights of each animal, simultaneously that these weights can be uploaded to a cloud server for later analysis.
    [0005]
    [0006] Technical problem to solve and background of the invention
    [0007] Currently, the weighing systems for livestock are known, among which it is worth highlighting the patent with application number in Spain P 201531709, which is the property of the same owner as the invention at hand.
    [0008]
    [0009] The weighing system of said patent comprises a dynamic weighing platform that indicates the value of the weight obtained; further comprising a control device, a detection system and a marking device. The described weighing system has a lack of precision and is also easy to commit. Said weighing system has the limitation of not allowing to carry out a control of the weight of the animals in real time.
    [0010]
    [0011] Description of the Invention
    [0012] In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a weighing scale for livestock and the weighing system.
    [0013]
    [0014] The scale includes in principle a weighing platform and a load cell located underneath the weighing platform; where the weighing platform is linked to a support structure that is part of the scale.
    [0015]
    [0016] The support structure comprises a first side with a tubular configuration, a second side with a tubular configuration, two cross tubes arranged in the same direction, a rear tube, a support with a transverse foot and a vertical post with a tubular configuration.
    [0017]
    [0018] The two cross tubes converge at one of their ends on the rear tube, while the other ends of the two cross tubes are attached to the first side and the second side; where the vertical post is joined by one of its ends to the first lateral; and where opposite ends of the transverse foot support are attached to the first side and the second side.
    [0019]
    [0020] The weighing platform includes two collateral parts separated by a hollow rib that is part of the weighing platform and that is above the collateral parts; where said collateral parts are configured for the separate support of the two front legs of an animal to be able to carry out its weighing; and where the load cell is located in the space delimited by said hollow rib of the weighing platform.
    [0021]
    [0022] The scale further comprises an upper support to which a connection box is attached; where said upper support is fixed to an extreme section of the vertical post above the first lateral; and where the internal space of the vertical pole communicates with the internal space of the junction box.
    [0023]
    [0024] In the areas of union between the tubular elements that make up the support structure of the scale, steps are configured that communicate the internal spaces of said tubular elements.
    [0025]
    [0026] The first lateral and the second lateral comprise C-shaped tubes that include lower branches, upper branches and cross members; where the upper branch of the first lateral is attached to the vertical post; and where the lower branches of the first side and the second side are joined by the foot support and by the transverse tubes that are also joined by their converging ends to the rear tube.
    [0027] A box-shaped protector is fixed on the first side, while a side closing plate is fixed on the second side.
    [0028]
    [0029] The load cell is encapsulated within a space delimited by the rear tube and by a front tube arranged in the same direction as the rear tube; where adjacent ends of the front tube and the rear tube converge in an elastic seal that separates both tubes; and where ends remote from the front tube and the rear tube are closed, respectively, by a first cap and by a second cap.
    [0030]
    [0031] The front tube is attached to the weighing platform by means of screws inserted in opposite holes located in the weighing platform and in plates attached to the front tube; where said screws thread into nuts located below said plates.
    [0032]
    [0033] The scale comprises articulated legs threaded into nuts that are welded to the transverse foot support.
    [0034]
    [0035] The load cell is fixed to the front tube by means of two pairs of opposing screws that thread in opposite holes located in the load cell, at the same time that these screws pass through holes in the front tube; where said screws also pass through holes located in flat sheets sandwiched between the load cell and the front tube.
    [0036]
    [0037] An inner edge of the weighing platform includes an angular bend adapted to the shape of the two rear tubes arranged in the same direction.
    [0038]
    [0039] The ends of the first side and the second side include anchor plates that are configured to fix the scale to a wall.
    [0040]
    [0041] The invention also relates to the livestock weighing system with the described scale; where said weighing system includes:
    [0042] - A processor that receives each weighing of the animal carried out by the load cell together with the identification of an identifying chip of the animal that has been weighed; where said processor is configured to store the different data obtained from the identification and weighing of each animal; and where the processor is configured to establish the average of various two-legged weights of each animal for a previously selected period of time.
    [0043]
    [0044] - Means configured to establish, by means of a conversion factor, the equivalent of the weight on two legs to the weight on four legs of each animal.
    [0045]
    [0046] The means configured to establish, by means of a conversion factor, the equivalent of the weight of the animal to two legs to four legs, are selected between a cloud and the processor; where the conversion factor is delimited between 1 and 2.
    [0047]
    [0048] The processor receives the animal's identification data wirelessly through an antenna that is attached to an internal face of the protector.
    [0049]
    [0050] Below, to facilitate a better understanding of this specification and forming an integral part thereof, a series of figures is attached in which the object of the invention has been represented by way of illustration and not limitation.

    [0060]
    [0061] Description of an embodiment of the invention
    [0062] Considering the numbering adopted in the figures, the system for weighing cattle, mainly pigs, is able to determine the weight of the pig only with the weight obtained by placing the two front legs of the pig on a scale 1 that includes a load cell 9 to detect the weight of the pig; where the scale 1 is also an object of the invention.
    [0063] The scale 1 comprises a support structure formed by a first side 2, a second side 3, two transverse tubes 4a, 4b in the same direction, a rear tube 5a, and a tubular vertical post 6; where the two cross tubes 4a, 4b converge at one of their ends on the rear tube 5a, while the other ends of the two cross tubes 4a, 4b are joined to the first side 2 and the second side 3; and where the vertical post 6 is joined by one of its ends to the first lateral 2; and where the first side 2 and the second side 3 are configured by tubes with a C-shaped configuration.
    [0064]
    [0065] The scale support structure further comprises a transverse foot support 7 that also joins the first side 2 and the second side 3.
    [0066]
    [0067] The scale 1 further comprises a weighing platform 8 associated with the two cross tubes 5a, 5b; wherein said weighing platform 8 includes two collateral parts 8a separated by a hollow rib 8b that forms part of the weighing platform 8; where on said collateral parts 8a rest the two front legs of the pig to be able to carry out its weighing. Underneath the weighing platform 8 is arranged the load cell 9 located in correspondence with the interior space delimited by said hollow rib 8b.
    [0068]
    [0069] Load cell 1 is made of stainless steel material, while working with the flexion of internal strain gages.
    [0070]
    [0071] A front part of the load cell 9 is housed inside a front tube 5b, so that one end of said front tube 5b is covered with a first cover 10 that is part of the encapsulation of the load cell 9. On said tube Two plates 11 are welded to the front 5b with welded nuts 12 that will serve to anchor this set of elements to the weighing platform 9 by means of screws 26 that screw into said nuts 12.
    [0072]
    [0073] The assembly of the scale 1 includes at least one flat plate 13 as a galce with two holes that serves to separate a front part of the load cell 9 from the weighing platform 8. With this flat plate 13 it is avoided that when placing a weight on the weighing platform 8 touches the load cell 9 due to the twisting of the materials.
    [0074] The weighing platform 8 is anchored to the assembly of the front tube 5b and load cell 9, so that all the weight that falls on said weighing platform 8 is transmitted directly to the load cell 9; where the ground measurements of said weighing platform 8 can be 250 cm. x 376 cm. with a thickness of 3 mm.
    [0075]
    [0076] The weighing platform 8 has the two well defined collateral parts 8a, 8b in which the pigs are going to place the hooves of their front legs. The bottom of weighing platform 8 has been reduced to the maximum to prevent more than one pig from being loaded onto it at one time.
    [0077]
    [0078] An inner edge of the weighing platform 8 includes an angle bend 8c which has a dual function. On the one hand, damage to the pig's hoof is avoided in an existing live edge when the angular bend is not configured, and on the other hand, the weighing area of the weighing platform 8 is enlarged. In small pigs it has been observed in the different tests that came to place the hooves on top of said live song.
    [0079]
    [0080] For the manufacture of the weighing platform 8, a first flat piece is used to support the pig's front legs, and a second piece welded to the first piece; where the second part constitutes the hollow rib 8b in the central area where the load cell 9 is housed together with the rear tube 5a and the front tube 5b.
    [0081]
    [0082] The scale 1 assembly comprises the metal support structure that supports the entire assembly. This support structure is formed by tubular elements mentioned above and serves for the wiring to pass through its interior space; where in an embodiment of the invention the section of the tubular elements of the support structure is 40 mm. x 40 mm. with a thickness of 2 mm.
    [0083]
    [0084] Said support structure serves to pass through the wiring of the load cell 9 and also the wiring of an RFID antenna 14 that is part of the weighing system. The shape of the curved corners of the support structure facilitate the passage of the cables, both in the assembly and in a possible repair.
    [0085]
    [0086] The first side 2 and the second side 3 incorporate anchor plates 15 at their ends to firmly fix the whole of the scale 1 to a wall of a pen in which the pigs are located. In one embodiment of the invention, the anchor plates 15 have a thickness of 4 mm.
    [0087]
    [0088] In addition, the first right side 2 functions as a support to support an antenna protector 16, while the second left side 3 functions as a support to support a side closure plate 17; where said antenna 14 is housed within a pocket of the protector 16.
    [0089]
    [0090] The side closure plate 17 has the function of preventing the pigs from sticking their heads out from the second left side 3 and causing false weights. In tests carried out, the larger pigs could access the feeder laterally without having to step on the weighing platform 8 of scale 1 with both hooves, producing erroneous weights lower than the actual weights.
    [0091]
    [0092] The antenna protector 16, in addition to serving as a support, acts as a screen to avoid reading an identification chip from each pig that is not supported by its front legs on the weighing platform 8.
    [0093]
    [0094] After various tests with different prototypes, it was observed that without the inclusion of the antenna protector 16, weight readings were obtained from pigs that were not raised on the weighing platform 8, but passed close to the antenna 14.
    [0095]
    [0096] It was observed that the reading field placing the antenna protector 16 was considerably reduced, avoiding these erroneous readings. Ten centimeters was determined to be more than enough distance to avoid erroneous readings; where in an embodiment of the invention the thickness of the antenna protector 16 is 1.5 mm.
    [0097]
    [0098] The first side 2 and the second side 3 are joined together by various elements, as described above: firstly, by means of the transverse foot support 7, which gives consistency to the support structure of the scale 1 and also allows the placement of two articulated legs 18 threaded to nuts 19 welded to the transverse foot support 7. These articulated legs 18 serve to be able to level the scale 1 on the corral floor.
    [0099]
    [0100] Secondly, the first side 2 and the second side 3 are connected to each other by means of the two transverse tubes 4a, 4b and the rear tube 5a that houses part of the load 9. The two sides 2, 3 formed by tubular elements, allow the cables of the load cell 9 to pass through its interior and also through the interior of the two transversal tubes 4a, 4b.
    [0101]
    [0102] The rear tube 5a together with the front tube 5b are arranged in the same longitudinal direction and house the load cell assembly 9 inside; thus achieving encapsulation of the load cell 9 and preventing moisture and dirt from entering it.
    [0103]
    [0104] The front tube 5b and the rear tube 5a are facing each other at one of their ends with the interposition of a natural rubber elastic joint 20 that ensures the tightness of the assembly while allowing the flexing of the load cell 9 without causing alteration in reading the detected weight. One end of the front tube 5b is closed by the first cap 10 while one end of the rear tube 5a is closed by a second cap 21.
    [0105]
    [0106] This solution of two separate pieces was chosen together with the elastic seal 20 made of natural rubber after making several prototypes where a good degree of sealing was not achieved, causing the load cell 9 to be damaged by dirt, making it unusable. .
    [0107]
    [0108] The assembly of the scale 1 is completed with the vertical post 6 and an upper support 22 fixed to said vertical post 6 through which the cables of the antenna 14 and the load cell 9 will go up to said upper support 22.
    [0109]
    [0110] On said upper support 22 is screwed a connection box 23 that houses inside it the antenna 14 and a processor 24 such as a CPU. The location of the junction box 23 allows us to have the electronics accessible in case we have to open said junction box 23 and take it outside the radius of the pigs and avoid breaking it.
    [0111]
    [0112] The load cell 9 is anchored to the front tube 5b by means of two pairs of screws 25, while countersunk screws 26 are used to connect the weighing platform 8 to the encapsulation of the load cell 9, which is formed by the front tube 5b and the rear tube 5a the first cap 10 the second cap 21 and the elastic joint. For this, said countersunk screws 26 are coupled to nuts 12 welded to plates 11 and to locknuts 27, while said countersunk screws 26 pass through facing holes in the weighing platform 8 and plates 11 welded to the front tube 5b .
    [0113]
    [0114] Thus, the load cell 9 is fixed to the front tube 5b by means of the two pairs of opposing screws 25 that thread in facing holes located in the load cell 9, at the same time that said screws 25 pass through holes front tube 5b. Said screws 25 also pass through holes located in flat sheets 13 sandwiched between the load cell 9 and the front tube 5b.
    [0115]
    [0116] Said flat plates 13 serve to give a margin of separation between the joined assembly formed by the front tube 5b and the rear tube 5a with respect to the load cell 9.
    [0117]
    [0118] RFID antenna 14 is placed on the first right side 2 of scale 1; where with said antenna 14 the readings of the identification chip incorporated in a tag are made just when the pig has its head inside a feeder 28 adjacent to scale 1. It is an identification system based on RFID technology, at the same time that the Ear tag is attached to the pig's right ear.
    [0119]
    [0120] The antenna 14 is fixed on an inside face of the protector 16, which serves to anchor said antenna 14 and avoid reading the identification chips when the pigs pass through the exterior of the scale 1.
    [0121]
    [0122] By means of the CPU 24 integrated in the scale 1, the history of the different weights of the pigs is uploaded to a server in a cloud 29 where they are subsequently analyzed. The CPU 24 is used to interconnect the different electronic elements, such as antenna 14 and load cell 9.
    [0123]
    [0124] The CPU 24 sends all the registered weights to a database where they are stored, so that from the data stored in the database, the theoretical weight of each pig is obtained by means of a mathematical formula.
    [0125]
    [0126] A software calculates the theoretical weight of the pig taking into account all the weighings recorded for each pig (dispersion of weights), the weeks of life of the pig on the day of registration of the weights and their sex. Different factors are applied to the weight caught on two legs to obtain the theoretical weight of the pig.
    [0127]
    [0128] It should be noted that the weights recorded only correspond to the weight captured when placing the two front legs and that we will not obtain on the scale 1 the total weight of the pig directly. Taking into account that morphologically pigs have a very similar body structure, the theoretical weight is calculated from the weights obtained from two front legs of the pig.
    [0129]
    [0130] All the connections of the electronic elements are made in the connection box 24. Inside it, the CPU 24 is housed, which has a series of electronic terminals where cables from the load cell 9 and other cables from the 14 RFID antenna. As previously mentioned, the cables reach the connection box 23 inside the support structure of the scale 1. In this way the cables are protected from dirt, humidity and out of the reach of the pigs.
    [0131]
    [0132] Scale 1 records the weight of each pig each time said pig places its head in feeder 28 by means of said pig's identification chip, which is normally incorporated in the ear tag attached to one of the pig's ears. Obviously scale 1 is located next to feeder 28.
    [0133]
    [0134] At the end of each day, scale 1 provides a reference weight for each pig, taking into account all the partial weighings that have been registered on that day and that correspond to all the times that the pig has come to feed the feeder 28. This data is uploaded to a cloud database 29 automatically by a hub that sends the weights of all scales 1 via an internet connection.
    [0135]
    [0136] Each weight delivered by scale 1 corresponds to the weight obtained from weighing the pig only on 2 legs and not the weight that would be obtained from weighing the pig on all four legs.
    [0137]
    [0138] To convert that weight on 2 legs to a weight on 4 legs of the pig, a series of calculations using software that takes into account on the one hand the characteristics of scale 1, such as the height of weighing platform 8 of scale 1 with respect to the ground, and on the other hand, takes into account the comparison of weights to 2 legs with heavy 4 legs from the same pigs on the same dates; where the four-legged weighing is carried out on scales other than scales 1 on which the two legs of the pig rest.
    [0139]
    [0140] Every time a pig places its head in feeder 28, scale 1 records the pig using its identification chip, as well as its weight.
    [0141]
    [0142] In this way we obtain a personalized calculation equation for each scale and in different ranges of life of each pig.
    [0143]
    [0144] These equations have been obtained to a large extent from previous studies with prototypes of this same scale 1 during several fattening cycles. The weights once converted from 2 legs to 4 legs are registered in the database to which the different departments of the company have access so that they can use them in their statistics or processes using different platforms such as Web or Power Bl.
    [0145]
    [0146] The CPU 24 itself is the one that registers the weights obtained each time the identification chip of a pig's tag is identified.
    [0147]
    [0148] The multiple weights recorded for each pig each day are stored in the cloud database 29 with the following data structure.
    [0149]
    [0150]
    [0151]
    [0152]
    [0153]
    [0154] In each weight range, the number of registered weights within that weight range is stored. In the visit boxes we register the number of pesos registered for each hour of the day. The occupation box indicates in seconds the time the pig is eating. Both occupancy and visit data are used to generate statistics or to rule out possible results due to having little data to work with.
    [0155]
    [0156] The first step is to identify a strip of five consecutive weights that represent a larger percentage of the total weights registered for each animal and day; all this using the "Gaussian algorithm".
    [0157]
    [0158] Once the calculated weight corresponding to the weight of the pig is obtained with the support of two legs we have to carry out a conversion by applying a factor to convert it to a total weight of the pig as if it were supporting it on its four legs.
    [0159]
    [0160] This factor takes into account several factors. On the one hand we have the age and sex of the pigs at the time of weight capture and on the other hand the physical characteristics of the scale itself. Although all the scales have the same components, once these components are assembled and once the scale 1 has been placed in the correct place inside the pen, there may be differences between these scales 1, such as the height of the weighing platform 8 with respect to the soil, so that at a lower height of the weighing platform 8, a better distribution of the weight of the pig on its 4 legs is obtained.
    [0161]
    [0162] In order to have a customized conversion formula for each scale 1, a series of pigs weight captures on different dates is made in all the pens with other different scales that take the weight of the pig on all fours and compare it with the captured weight by two-legged pen scale 1 to obtain a specific conversion factor for each scale 1 according to the age of the pigs.
    [0163]
    [0164] An example of the application of the Gaussian algorithm with data is described below. Thus, we take as a base the internal memory of scale 1 where we have the weights recorded for each weight range (weight 0 to 100).
    [0165]
    [0166]
    [0167]
    [0168]
    [0169] First, the 5 most significant ranges of consecutive weights are sought.
    [0170]
    [0171] Next, it is observed that these weights are those included in the P26kg range. and the one of P30kg.
    [0172]
    [0173] Sum of weights of chosen ranges:
    [0174] (p26 + p27 p28 p29 p30) =
    [0175] (15 + 23 + 43 + 47 + 19) = 147.
    [0176]
    [0177] It should be noted that the weight of each range of 0.5 kg is taken as the weight of each range since the scale only registers weights for ranges of 1 Kg.
    [0178] In this way, the rest of the ranges are discarded and a calculation is made to obtain a 2-legged weight, taking into account the ranges selected with the following formula:
    [0179] (P26 * 26.5) / SUM_PESOS (P27 * 27.5) / SUM_PESOS
    [0180] (P28 * 28.5) / SUM_PESOS (P29 * 29.5) / SUM_PESOS
    [0181] (P30 * 30.5) / SUM_PESOS
    [0182]
    [0183] (15 * 26.5) / 147 (23 * 27.5) / 147 (43 * 28.5) / 147 (47 * 29.5) / 147
    [0184] (19 * 30.5) / 147 =
    [0185] 28.71 (result weight on 2 legs)
    [0186]
    [0187] Once we have the weight calculated on two legs and published in cloud 29, we apply the corresponding conversion to obtain the weight on 4 legs with the following formula:
    [0188]
    [0189] Weight on 2 legs * Conversion factor = Weight on 4 legs = 28.71 * 1.69432572 = 48.64 kg.
    [0190]
    [0191] The conversion factor is obtained from different weighing histories of pigs on 4 legs of the same pigs in different weeks of life, so that from these same pigs a series of weight data is obtained that can be compared with the weights. obtained on two legs by the scale 1 of the invention located in the corral. Each scale 1 of the invention will have its own conversion factors according to the weight obtained on two legs.
    [0192]
    [0193] The height of the weighing platform 8 and the physical characteristics of each scale 1 interfere in the calculations of the factors of each scale 1.
    [0194]
    [0195] The conversion factor is a living data that is polished as data is obtained from real weighing on four legs of pigs with which to compare with those obtained on two legs.
    [0196]
    [0197] Based on the history of weights on four legs and their weights on two legs, a table similar to this one is obtained with more or less details according to the available data, as shown below in an example for a specific scale 1.
    [0198]

    [0201] In the case of this example, the weight obtained of 28.71 kg is located. in the table and multiply by the corresponding conversion factor: 1.694
    [0202]
    [0203] The table shown serves for a specific genetics, so that each breed of pig has its physical characteristics and has a weight distribution that causes it to have different factors.
    [0204]
    [0205] In summary, therefore, the main objective of scale 1 is to have a control of the weight of the animals in real time, so that with this data it is possible to detect a weight loss of a pig in time and to predict possible diseases, physical damages in this or unfavorable environmental conditions on the farm.
    [0206] Another objective is to be able to predict the number of animals and which animals have to leave for the slaughterhouse according to a fixed weight without having to carry out massive pig-to-pig weighing as is being done right now or not to use a visual criterion to “mark” the pigs with higher weights so that they leave for the slaughterhouse.
    [0207]
    [0208] Scale 1 records each time a pig places its head in feeder 28 thanks to the identification chip incorporated in the ear tag, controlling a series of weights.
    [0209]
    [0210] The livestock weighing system learns from itself and with the data it collects for each scale and the weight differences of the four-legged scales, refining the conversion factor that corresponds to it as it grows and gains weight.
