APARATO Y PROCESO PARA ELABORAR BOLAS O MADEJAS DE QUESO DE  APPARATUS AND PROCESS TO PREPARE BALLS OR CHEESE TABLES
PASTA HILADA  WIRE PASTA
CAMPO TÉCNICO DE LA INVENCIÓN TECHNICAL FIELD OF THE INVENTION
Esta invención está relacionada generalmente a aparatos y procesos para elaborar quesos, en particular se refiere a un aparato y proceso para elaborar bolas o madejas de queso de pasta hilada a partir de una tira de pasta de hilada de queso que se engancha a una pinza con un movimiento angular sobre su eje de rotación horizontal y al mismo tiempo con un movimiento angular de vaivén sobre su eje de rotación vertical. This invention is generally related to apparatus and processes for making cheese, in particular it relates to an apparatus and process for making balls or skeins of spun-dough cheese from a strip of cheese-spun dough that is hooked to a clamp with an angular movement on its axis of horizontal rotation and at the same time with a reciprocating angular movement on its axis of vertical rotation.
ANTECEDENTES DE LA INVENCIÓN En la actualidad, el queso Oaxaca, Mozzarella, Provolone, Caciocavallo, Asadero y Quaje pertenecen al grupo de los quesos de pasta hilada debido a que durante su elaboración la cuajada, previamente acidificada, se somete a un amasado con agua caliente que permite plastificarla y estirarla; de tal forma que pueda formar bandas, a su vez constituidas por estructuras un tanto alineadas que se pueden separar como "hilos". BACKGROUND OF THE INVENTION At present, Oaxaca, Mozzarella, Provolone, Caciocavallo, Asadero and Quaje cheese belong to the group of spiced pasta cheeses because during their preparation the curd, previously acidified, is subjected to kneading with hot water that allows to plasticize and stretch it; in such a way that it can form bands, in turn constituted by somewhat aligned structures that can be separated as "threads".
A nivel internacional, el Mozzarella es el queso de pasta hilada más conocido; aunque en Europa también gozan de fama el Provolone y el Caciocavallo. En México, si bien se conoce el Mozzarella tipo americano (diferente al original, italiano, en varios aspectos), y cuya demanda parece incrementarse sensiblemente, el queso más conocido de esta familia es, sin duda, el Oaxaca. No obstante, en el país existen otros quesos de pasta-hilada, como el Asadero, el Guaje (elaborado en la Huasteca Potosina) y el Queso Trenzado, de Veracruz El queso Oaxaca guarda grandes semejanzas con el Mozzarella italiano, por su forma y proceso general, sobre todo cuando ambos se fabrican artesanalmente. Esto a pesar de que el queso italiano desde antaño se elabora con leche de búfala, y el mexicano con leche de vaca (curiosamente, la leche de cabra no es adecuada para elaborarlo, ya que la pasta no "hila" porque no tiene capacidad suficiente de estiramiento, y se rompe). Internationally, Mozzarella is the best known spiced pasta cheese; although Provolone and Caciocavallo also enjoy fame in Europe. In Mexico, although the American type Mozzarella is known (different from the original, Italian, in several aspects), and whose demand seems to increase significantly, the best known cheese of this family is, without a doubt, Oaxaca. However, there are other pasta-spiced cheeses in the country, such as Asadero, Guaje (made in Huasteca Potosina) and Braided Cheese, from Veracruz Oaxaca cheese has great similarities with the Italian Mozzarella, due to its general shape and process, especially when both are manufactured by hand. This is despite the fact that Italian cheese has been made with buffalo milk since ancient times, and Mexican cheese with cow's milk (interestingly, goat's milk is not suitable for making it, since the pasta does not "spin" because it does not have enough capacity stretching, and it breaks).
La textura característica de los quesos de pasta hilada puede explicarse, por el rearreglo estructural que las moléculas de caseína sufren al someterse la pasta a calentamiento y trabajo mecánico. Este, desarrollado durante el amasado, y el ascenso de temperatura por el aporte de agua caliente, provocaría la desnaturalización de parte de las moléculas de caseína, alterando su conformación β- placa y a-hélice.  The characteristic texture of spiced pasta cheeses can be explained by the structural rearrangement that casein molecules suffer when the dough is subjected to heating and mechanical work. This, developed during kneading, and the rise in temperature by the supply of hot water, would cause denaturation of part of the casein molecules, altering their β-plate and a-helix conformation.
La continuación de la acción mecánica, y el estiramiento al que se somete la pasta en un sentido (dirección) espacial, orientarían y "alinearían" a las proteínas, cual si fueran agregados de "hilos". Entre moléculas contiguas de proteínas alineadas se establecerían enlaces químicos de distinta naturaleza (por ejemplo, por puentes de hidrógeno) que las mantendrían unidas.  The continuation of the mechanical action, and the stretching to which the paste is subjected in a spatial (direction) direction, would orient and "align" the proteins, as if they were aggregates of "threads". Between adjacent molecules of aligned proteins, chemical bonds of a different nature would be established (for example, by hydrogen bonds) that would hold them together.
Asimismo, la grasa butírica, ya en la pasta amasada e hilada, se distribuiría en Likewise, butyric fat, already in kneaded and spun pasta, would be distributed in
"columnas" largas, siguiendo la orientación de los arreglos de las fibras caseínicas. La grasa estaría flotando, también, en "microcisternas" de suero y, de alguna forma, funcionaría como un lubricante durante la alineación de las fibras de caseína durante el trabajo mecánico del amasado e hilado. long "columns", following the orientation of the arrangements of the casein fibers. The fat would also be floating in serum "microcisters" and, in some way, would function as a lubricant during the alignment of casein fibers during the mechanical work of kneading and spinning.
Sin embargo, en la actualidad para dar un acabado de bola o madeja a estos tipos de queso se realiza un proceso meramente artesanal que consiste en arrollar manualmente una tira de pasta hilada de queso a manera de bola o madeja. Es por tanto necesario ofrecer un aparato para elaborar bolas o madejas de queso a partir de una tira de pasta de queso hilada siendo alimentada. OBJETO DE LA INVENCIÓN However, at present to give a ball or skein finish to these types of cheese a purely handmade process is carried out that consists of manually winding a strip of spun cheese paste as a ball or skein. It is therefore necessary to offer an apparatus for making balls or skeins of cheese from a strip of spun cheese paste being fed. OBJECT OF THE INVENTION

Ei canal de alimentación 20 está elaborada de acero inoxidable en forma de canal de sección transversal curvo y está montado sobre una estructura (no mostrada) sobre la parte superior de dicho aparato 10. El canal de alimentación 20 tiene un tramo horizontal 23 cuyo extremo libre 26 hace una curvatura vertical conectándose a la tolva guía 30. Por el canal de alimentación 20 se suministra al aparato 10 una tira de pasta hilada de queso que se va desplazando continua y lentamente sobra su superficie. An apparatus 10 for making balls or skeins of spun-dough cheese according to the invention is illustrated in Figures 1 to 5. The apparatus 10 is formed by a feed channel 20, a guide hopper 30, a first position sensor 40, a roller motor 50, a feed piston 60, a blade 70, a winding clamp 80, a first motor 90 , a second position sensor 100, an ejector 110, a base 120, a second motor 130, an axle support 140, one or more load cells 150 and a cover 160. The feed channel 20 is made of stainless steel in the form of a curved cross-section channel and is mounted on a structure (not shown) on the top of said apparatus 10. The feed channel 20 has a horizontal section 23 whose free end 26 makes a vertical curvature by connecting to the guide hopper 30. A strip of spun cheese paste that is continuously and slowly moving over its surface is supplied to the apparatus 10 via the feed channel 20.
La tolva guía 30 está elaborada de acero inoxidable y está conectada por su base mayor 33 al extremo libre 26 del canal de alimentación 20 y por su base menor 36 sale orientada y alineada verticalmente la tira de pasta hilada de queso alimentada por el canal de alimentación 20.  The guide hopper 30 is made of stainless steel and is connected by its major base 33 to the free end 26 of the feed channel 20 and by its minor base 36 the strip of spun cheese paste fed by the feed channel is oriented and aligned vertically. twenty.
Entre la tolva guía 30 y el extremo libre del canal de alimentación 20 se encuentra conectado el primer sensor de posición 40 del tipo final de carrera, capacitivo, inductivo, fotoeléctrico, infrarrojo, o combinación de ellos, de tal manera que el primer sensor de posición 40 percibe la presencia del extremo de la tira de pasta hilada de queso entrando a la base mayor 33 de la tolva guía 30, generando una señal que activa el arranque del motor de rodillos 50 cuyos rodillos sujetan la tira de pasta hilada de queso siendo alimentada por el canal de alimentación 20. El motor de rodillos 50 empuja mediante sus rodillos 55 a la tira de pasta hilada de queso provocando que ésta tenga un avance y velocidad controlada de alimentación.  Between the guide hopper 30 and the free end of the feed channel 20, the first position sensor 40 of the limit switch type, capacitive, inductive, photoelectric, infrared, or combination thereof is connected, such that the first sensor position 40 perceives the presence of the end of the strip of cheese spun paste entering the main base 33 of the guide hopper 30, generating a signal that activates the start of the roller motor 50 whose rollers hold the strip of cheese spun pasta being fed by the feed channel 20. The roller motor 50 pushes through its rollers 55 the strip of cheese spun paste causing it to have a feed rate and controlled feed rate.
La cuchilla 70 está hecha de acero inoxidable y está montada de manera cercana a la base menor 36 de la tolva guía 30. La cuchilla 70 sirve para cortar la tira de pasta hilada de queso siendo alimentada, bajo la determinación de que la bola o madeja de queso ha sido terminada. La cuchilla 70 está conectada a un servo- mecanismo 180 del tipo pistón, bien sea hidráulico o neumático, que es activado por una señal una vez que se ha determinado que la bola o madeja de queso ha sido terminada. La tolva guía 30, el primer sensor de posición 40, el motor de rodillos 50 y la cuchilla 70 están montados en una estructura 190 sujeta al émbolo del pistón de avance 60. El pistón de avance 60 es accionado por la señal de primer sensor de posición 40 al momento de percibir la entrada a la tolva guía 30 del extremo de la tira de pasta hilado de queso, provocando que la estructura 190 y todo los elementos sujetos a ella avancen en dirección vertical con el fin de acercar el extremo de la tira de pasta hilado de queso a la pinza de enrollado 80. Una vez que la bola o madeja de queso ha sido terminada, el émbolo del pistón de avance 60 se retrae junto con la estructura 190 a su posición original. El pistón de avance 60 es del tipo hidráulico o neumático controlado en cuanto a su carrera y velocidad de avance a través de un Controlador Lógico Programable (PLC). The blade 70 is made of stainless steel and is mounted close to the smaller base 36 of the guide hopper 30. The blade 70 is used to cut the strip of spun cheese paste being fed, under the determination that the ball or skein of cheese has been finished. The blade 70 is connected to a servo-mechanism 180 of the piston type, either hydraulic or pneumatic, which is activated by a signal once it has been determined that the cheese ball or skein has been terminated. The guide hopper 30, the first position sensor 40, the roller motor 50 and the blade 70 are mounted in a structure 190 attached to the piston of the feed piston 60. The feed piston 60 is driven by the signal of the first sensor of position 40 at the time of perceiving the entrance to the guide hopper 30 of the end of the strip of cheese spun paste, causing the structure 190 and all the elements subject to it to advance in a vertical direction in order to bring the end of the strip of spun cheese paste to the winding clamp 80. Once the cheese ball or skein has been finished, the plunger of the feed piston 60 retracts together with the structure 190 to its original position. The feed piston 60 is of the hydraulic or pneumatic type controlled in terms of its stroke and feed rate through a Programmable Logic Controller (PLC).
Por debajo de la base menor 36 de la tolva guía 30 se encuentra la pinza de enrollado 80, la cual está conectada horizontal mente por un extremo 81 al eje del primer motor 90 colocado en posición horizontal. La pinza de enrollado 80 está formada por una barra de acero inoxidable cuyo extremo libre 82 tiene un ojal 83 en su parte central y que a su vez el centro del ojal 83 está alineado verticalmente con la base menor 36 de la tolva guía 30. El ojal 83 está definido por paredes interiores 84 en donde al menos una de ellas, preferentemente la pared que queda opuesta al extremo 81 de la pinza de enrollado 80 que se conecta al eje del primer motor 50, tiene forma de cuchilla 85.  Below the smaller base 36 of the guide hopper 30 is the winding clip 80, which is connected horizontally by one end 81 to the axis of the first motor 90 placed horizontally. The winding clamp 80 is formed by a stainless steel bar whose free end 82 has an eyelet 83 in its central part and which in turn the center of the eyelet 83 is vertically aligned with the smaller base 36 of the guide hopper 30. The eyelet 83 is defined by inner walls 84 where at least one of them, preferably the wall that is opposite the end 81 of the winding clamp 80 which is connected to the axis of the first motor 50, is in the form of a blade 85.
La pinza de enrollado 80 tiene un movimiento giratorio sobre su eje horizontal a favor o en contra de las manecillas del reloj (representado este movimiento en la Figura 1 por la flecha sólida curva), y este movimiento es producido por el primer motor 90 al cual está conectado. El primer motor 90 puede estar formador por un motor eléctrico o por un motor eléctrico conectado a una caja reductora, en donde el motor eléctrico es alimentado por corriente alterna o directa. Preferentemente, el primer motor 90 es un servomotor con carcasa y eje de acero inoxidable controlado a través de PLC para controlar la velocidad de giro de su eje y su torque. El primer motor 90 está montado de manera horizontal sobre un extremo del soporte-eje 140 que a su vez le permite ajustar un ángulo de inclinación β de -45° a 45° respecto de la horizontal. The winding clamp 80 has a rotating movement on its horizontal axis in favor or against the hands of the clock (represented this movement in Figure 1 by the solid curved arrow), and this movement is produced by the first motor 90 to which Are you connected. The first motor 90 may be formed by an electric motor or by an electric motor connected to a gearbox, where the electric motor is powered by alternating or direct current. Preferably, the first motor 90 is a servo motor with stainless steel housing and shaft controlled through PLC to control the speed of rotation of its axis and its torque. The first Motor 90 is mounted horizontally on one end of the shaft support 140 which in turn allows it to adjust an angle of inclination β of -45 ° to 45 ° with respect to the horizontal.
El hecho de que el primer motor 90 se pueda colocar en una posición horizontal, con un ángulo de inclinación β variable de entre de -45° a 45° respecto de la horizontal, le permite al aparato 10 formar bolas o madejas de queso que van desde formas substancialmente esféricas hasta formas ovaladas o de lados chatos.  The fact that the first motor 90 can be placed in a horizontal position, with an angle of inclination β varying from -45 ° to 45 ° with respect to the horizontal, allows the apparatus 10 to form balls or skeins of cheese that go from substantially spherical shapes to oval or flat-sided shapes.
El segundo sensor de posición 100 está alineado horizontalmente con el ojal 83 de la pinza de enrollado 80 y está colocando en el extremo libre de un brazo 190 en forma de arco conectado a la cubierta del primer motor 90. El segundo sensor de posición 100 puede ser un sensor del tipo final de carrera, capacitivo, inductivo, fotoeléctrico, infrarrojo, o combinación de ellos, de tal manera que el segundo sensor de posición 100 percibe la presencia del extremo de la tira de pasta hilada de queso entrando al ojal 83 de la pinza de enrollado 80 para producir el arranque del primer motor 90 y por ende el giro de la pinza de enrollado 80 provocando que el extremo de la tira de pasta hilada de queso que entro al ojal 83 se enganche e iniciar el arrollamiento de ésta.  The second position sensor 100 is aligned horizontally with the eyelet 83 of the winding clamp 80 and is placed at the free end of an arc-shaped arm 190 connected to the cover of the first motor 90. The second position sensor 100 can be a sensor of the end of the race type, capacitive, inductive, photoelectric, infrared, or combination thereof, such that the second position sensor 100 perceives the presence of the end of the strip of cheese spun paste entering the eyelet 83 of the winding clamp 80 to cause the first motor 90 to start and hence the rotation of the winding clamp 80 causing the end of the strip of spun cheese paste that entered the eyelet 83 to catch and start winding it.
En el frente del primer motor 90 se encuentra el expulsor 110 que es retráctil y está formado por una placa curva 111 con un orificio central 112 para dejar libre el paso al eje del motor y a la pinza de enrollado 80. La placa curva 111 a su vez está conectada por sus extremos a los émbolos de una pluralidad de pistones 112 cuyos cilindros a su vez están colocados y sujetos alrededor de la carcasa del primer motor 90. Los pistones 112 pueden ser del tipo hidráulico o neumático controlado por PLC en cuanto a su velocidad y distancia de avance de respectivo émbolo. La placa curva 111, una vez que la bola o madeja de queso ha sido terminada, avanza con ayuda de los pistones 112 con propósito de empujar a la bola o madeja de queso y liberarla de la pinza de enrollado 90 la cual a su vez con la cuchilla 85 del ojal 83 facilita la salida de la bo'a o madeja de queso. Sobre la base 120 se encuentra el soporte-eje 140, que en una realización, es una estructura en forma de "L" compuesta por un brazo vertical 141 y brazo horizontal 142, tal que el extremo libre del brazo vertical 141 sujeta la carcasa del primer motor 90 y el extremo libre del brazo horizontal 142 está conectado perpendicularmente al eje del segundo motor 130 en posición vertical, tal que el segundo motor 130 proporciona al soporte-eje 140 un movimiento angular de vaivén sobre su eje de rotación vertical con un ángulo φ de 0o a 360° (representado este movimiento en las Figuras 1 y 4 por la doble flecha sólida curva). El segundo motor 130 puede estar formador por un motor eléctrico o por un motor eléctrico conectado a una caja reductora, en donde el motor eléctrico es alimentado por corriente alterna o directa. Preferentemente, el segundo motor 130 es un servomotor con carcasa y eje de acero inoxidable controlado a través de PLC para controlar la velocidad del movimiento angular de vaivén de su eje y su torque. On the front of the first motor 90 is the ejector 110 which is retractable and is formed by a curved plate 111 with a central hole 112 to free the passage to the motor shaft and the winding clamp 80. The curved plate 111 to its at the same time it is connected at its ends to the pistons of a plurality of pistons 112 whose cylinders are in turn placed and fastened around the housing of the first motor 90. The pistons 112 can be of the hydraulic or pneumatic type controlled by PLC in terms of their forward speed and distance of respective piston. The curved plate 111, once the cheese ball or skein has been finished, advances with the help of the pistons 112 in order to push the cheese ball or skein and release it from the winding clamp 90 which in turn with the blade 85 of the eyelet 83 facilitates the exit of the bo'a or skein of cheese. On the base 120 is the support-axis 140, which in one embodiment, is a "L" shaped structure composed of a vertical arm 141 and horizontal arm 142, such that the free end of the vertical arm 141 holds the housing of the first motor 90 and the free end of the horizontal arm 142 is connected perpendicularly to the axis of the second motor 130 in an upright position, such that the second motor 130 provides an angular reciprocating movement 140 on its axis of vertical rotation with an angle φ from 0 or 360 ° (this movement is represented in Figures 1 and 4 by the double solid arrow curve). The second motor 130 may be formed by an electric motor or by an electric motor connected to a gearbox, where the electric motor is powered by alternating or direct current. Preferably, the second motor 130 is a servo motor with stainless steel housing and shaft controlled through PLC to control the speed of the reciprocating angular movement of its axis and its torque.
El segundo sensor de posición 100 al producir el arranque del primer motor 90 al momento percibir la presencia del extremo de la tira de pasta hilada de queso entrando al ojal 83 de la pinza de enrollado 80, simultáneamente produce el arranque del segundo motor 130 y por ende el giro del soporte-eje 140 soporte-eje 140 para iniciar el arrollamiento de la tira de pasta hilada de queso siendo alimentada a través de la tolva guía 30.  The second position sensor 100 when starting the first motor 90 immediately senses the presence of the end of the strip of cheese spun paste entering the eyelet 83 of the winding clamp 80, simultaneously produces the start of the second motor 130 and then therefore the rotation of the support-axis 140 support-axis 140 to start the winding of the strip of cheese spun paste being fed through the guide hopper 30.
Por debajo de la base 120 se encuentran las celdas de carga 150 que pueden ser del tipo de galga semiconductora o de hilo o lámina conductora. Las celdas de carga 150 van percibiendo continuamente el peso de la bola o madeja de queso siendo elaborada y en el momento que perciben que la bola o madeja de queso ha alcanzado su peso determinado o programado, entonces genera una primera señal de paro del primer motor 90, del segundo motor 130 y del motor de rodillos 50 para dejara de arrollar y alimentar respectivamente la tira de pasta hilada de queso, a su vez genera una segunda señal para activar el servomecanismo 180 de la cuchilla 70 para cortar la tira de pasta hilada de queso siendo alimentada, una tercera señal para activar los pistones 112 del expulsor 110 para empujar a la bola o madeja de queso y liberarla de la pinza de enrollado 90 para que caiga sobre la cubierta 160, y una cuarta señal para retraer el émbolo del pistón de avance 60 junto con la estructura 190 a su posición original. Below the base 120 are the load cells 150 which can be of the type of semiconductor gauge or wire or conductive sheet. Load cells 150 continuously perceive the weight of the cheese ball or skein being processed and at the time they perceive that the cheese ball or skein has reached its determined or programmed weight, then generates a first stop signal from the first motor 90, of the second motor 130 and of the roller motor 50 to stop winding and feeding respectively the strip of cheese spun paste, in turn generates a second signal to activate the servo mechanism 180 of the blade 70 to cut the strip of spun dough of cheese being fed, a third signal for activate the pistons 112 of the ejector 110 to push the ball or skein of cheese and release it from the winding clamp 90 so that it falls on the cover 160, and a fourth signal to retract the plunger of the feed piston 60 together with the structure 190 to its original position.
La base 120, el segundo motor 130, soporte-eje 140, las celdas de carga 150 están dentro de una cubierta 160 la cual está sujeta al extremo libre del brazo horizontal 142 del soporte-eje 140, por ende la cubierta 160 también tiene un movimiento angular de vaivén sobre su eje de rotación vertical con un ángulo φ de 0o a 360°. The base 120, the second motor 130, support-axis 140, the load cells 150 are inside a cover 160 which is attached to the free end of the horizontal arm 142 of the support-axis 140, therefore the cover 160 also has a reciprocating angular movement on its axis of vertical rotation with an angle φ of 0 or 360 °.
Desde un punto de vista de realización lógica, e! aparato 10 cuenta con una memoria programable que almacena el peso máximo de la bola o madeja de queso a elaborar y los parámetros de operación. A su vez el aparato 10 cuenta con un procesador electrónico en conexión con la memoria programable, con el primer sensor de posición 40, el motor de rodillos 50, el pistón de avance 60, el servomecanismo 180 de la cuchilla 70, el primer motor 90, el segundo sensor de posición 100, el segundo motor 130, los pistones 112 del expulsor 110 y con las celdas de carga 150 para coordinar, ordenar y activar a cada uno de estos elementos conforme a su adecuada operación.  From a logical realization point of view, e! apparatus 10 has a programmable memory that stores the maximum weight of the ball or skein of cheese to be made and the operating parameters. In turn, the apparatus 10 has an electronic processor in connection with the programmable memory, with the first position sensor 40, the roller motor 50, the feed piston 60, the servo mechanism 180 of the blade 70, the first motor 90 , the second position sensor 100, the second motor 130, the pistons 112 of the ejector 110 and with the load cells 150 to coordinate, order and activate each of these elements according to their proper operation.
El funcionamiento del aparato para elaborar bolas o madejas de queso de pasta hilada de acuerdo a la invención opera de la siguiente manera :  The operation of the apparatus for making balls or skeins of spiced pasta cheese according to the invention operates as follows:
Una tira de pasta hilada de queso es colocada sobre el canal de alimentación 20. En el momento en el que el primer sensor de posición 40 colocado en la parte inferior de la canal de alimentación 20 detecte la presencia de la tira de pasta hilada de queso, éste genera una señal para activar el motor de los rodillos 50 que permite una avance continuo a través de la tolva guía 30 de la tira de pasta hilada de queso manteniéndola a una tensión constante.  A strip of spun cheese paste is placed on the feed channel 20. At the moment when the first position sensor 40 placed at the bottom of the feed channel 20 detects the presence of the strip of cheese spun pasta , this generates a signal to activate the motor of the rollers 50 which allows a continuous advance through the guide hopper 30 of the strip of cheese spun paste keeping it at a constant tension.
Después de una cierta cantidad de avances de la tira de pasta hilada de queso, se activa el pistón de avance 60 para que comience a bajar lentamente la estructura 190 y sus elementos conectados hacia la pinza de enrollado 80. Cuando el segundo sensor de posición 100 detecte que el extremo de la tira de pasta hilada de queso ya está colocado dentro del ojal 85 de la pinza de enrollado 80, generan una señal para activar el primer motor 90 comenzando el arrollamiento de la tira de pasta hilada de queso. De igual manera se activa simultáneamente el segundo motor 130 para que comience su movimiento angular de vaivén sobre su eje de rotación vertical dentro de un rango de entre 0o a 360°. Este movimiento angular de vaivén provoca que la tira de pasta hilada de queso conforme es arrollada por el primer motor 70 vaya adquiriendo la forma de una bola o madeja After a certain amount of advances of the strip of cheese spun paste, the advance piston 60 is activated so that the structure slowly begins to lower 190 and its elements connected to the winding clip 80. When the second position sensor 100 detects that the end of the strip of cheese paste is already placed inside the eyelet 85 of the winding clip 80, they generate a signal to activate the first motor 90 beginning the winding of the strip of cheese spun paste. In the same way, the second motor 130 is activated simultaneously so that it starts its angular reciprocating movement on its axis of vertical rotation within a range of between 0 or 360 °. This angular reciprocating movement causes the strip of spun cheese paste as it is rolled by the first motor 70 to take the form of a ball or skein
En cuanto el primer motor 70 empiece a funcionar, se deberá desactivar el pistón avance 60 para quela estructura 190 y demás elementos conectados a ella suban a su posición original.  As soon as the first engine 70 starts running, the feed piston 60 must be deactivated so that the structure 190 and other elements connected to it rise to their original position.
Las celdas de carga 150 están midiendo continuamente el peso de la bola o madeja de queso siendo formada. Estas celdas de carga 150 debe de estar calibradas correctamente, tomando en cuenta el peso de todos los elementos del aparato 10 que actúan directamente sobre de ella, la fuerza de la tensión producida por la tira de pasta hilada de queso y el peso de la bola o madeja de queso siendo formada en la pinza de enrollado 80. Por lo tanto aplicando la siguiente ecuación se podrá definir el peso definitivo con el que se activara la celda de carga 150 para indicar que la bola o madeja de queso tiene el peso necesario.  Load cells 150 are continuously measuring the weight of the ball or skein of cheese being formed. These load cells 150 must be correctly calibrated, taking into account the weight of all the elements of the apparatus 10 that act directly on it, the force of the tension produced by the strip of cheese spun paste and the weight of the ball or skein of cheese being formed in the winding clamp 80. Therefore, by applying the following equation, the definitive weight with which the load cell 150 will be activated can be defined to indicate that the cheese ball or skein has the necessary weight.
Mc = K + w - T [ 1 ] Mc = K + w - T [1]
En donde: Where:
Me es la medición de peso percibida por la celda conforme avanza el arrollamiento de la bola o madeja de queso.  It is the measurement of weight perceived by the cell as the roll of the ball or skein of cheese progresses.
K es una constante que indica el peso fijo que se tiene sobre la celda de carga, w es el peso de la bola o madeja de queso;  K is a constant that indicates the fixed weight on the load cell, w is the weight of the ball or skein of cheese;
T es la tensión ejercida por la tira de pasta de hilada de queso durante su alimentación a la pinza de enrollado. Una vez que la celda de carga 150 se activa, genera una serie de señales para detener el primer motor 70 y el segundo motor 130, así como el motor de rodillos 50 que controla la de tensión, el empuje y avance de la tira de pasta de hilada de queso. Si la celda de carga 150 sigue activada, y el primer motor 70 y segundo motor 130 se han detenido, entonces se activará el pistón de avance 60 que permite a la cuchilla 70 bajar hasta por encima de la pinza de enrollado 80. T is the tension exerted by the strip of cheese course during its feeding to the winding clamp. Once the load cell 150 is activated, it generates a series of signals to stop the first motor 70 and the second motor 130, as well as the roller motor 50 that controls the tension, thrust and feed of the pulp strip of cheese course. If the load cell 150 is still activated, and the first motor 70 and second motor 130 have stopped, then the feed piston 60 will be activated which allows the blade 70 to go down to above the winding clamp 80.
Con la utilización de sensores de avance 190, se sabe si el pistón de avance 60 de la cuchilla 70 se encuentra ya completamente en su posición final, si es así, se accionará el servomecanismo 180 para que su vástago salga completamente y permita que la chuchilla 70 corte la tira de pasta de hilada de queso. Si el sensor del servomecanismo 180 indica que ya termino su recorrido, entonces debe de contraerse de nuevo.  With the use of advance sensors 190, it is known if the advance piston 60 of the blade 70 is already completely in its final position, if so, the servomechanism 180 will be actuated so that its rod leaves completely and allows the knife 70 Cut the strip of cheese paste. If the servomechanism sensor 180 indicates that its journey is over, then it must contract again.
Cuando la cuchilla 70 haya terminado su proceso de corte se desactivará el servomecanismo 180, para que éste regrese a su posición inicial.  When the blade 70 has finished its cutting process, the servomechanism 180 will be deactivated, so that it returns to its initial position.
En el momento en que el sistema de corte comience a subir, se activarán los pistones 112 del expulsor 110 que ayuda a expulsar la bola o madeja queso formada. Los pistones 112 del expulsor 110 deben actuar de forma rápida expulsando la bola o madeja queso que se encuentra en la pinza de enrollado 80, por lo tanto una vez que termine su recorrido deberán de regresar a su posición original.  At the moment when the cutting system begins to rise, the pistons 112 of the ejector 110 will be activated which helps to expel the ball or skein formed cheese. The pistons 112 of the ejector 110 must act quickly by expelling the ball or skein cheese that is in the winding clamp 80, therefore once they have finished their journey they must return to their original position.
Si los pistones 112 del expulsor 110 ya se encuentran en reposo, el pistón de movimiento de la cuchilla 70 también se encuentra desactivado, y la celda de carga 150 deja de indicar que tiene el peso adecuado, entonces activarán de nuevo el motor de rodillos 50 para controlar la tensión y empuje de la tira de pasta de hilada de queso para comenzar de nuevo el proceso.  If the pistons 112 of the ejector 110 are already at rest, the piston movement of the blade 70 is also deactivated, and the load cell 150 ceases to indicate that it has the appropriate weight, then the roller motor 50 will be activated again. to control the tension and thrust of the strip of cheese paste to start the process again.
Para lograr saber cuál es la tensión óptima para arrollar una tira de pasta de hilada de queso en forma de bola o madeja de queso, se deberán de realizar pruebas variando las velocidades del motor de rodillos 50, y del sistema de arrollamiento, o bien, se pueden integrar variadores de velocidad para ajustar el par del motor de rodillos 50 y con esto obtener una velocidad ideal produciendo una tensión adecuada para poder arrollar una tira de pasta de hilada de queso. Se puede utilizar una señal de salida de la celda de carga 150 para que le vaya indicando el incremento de tamaño y peso de la bola o madeja de queso, y de acuerdo a esa señal, el variador pueda ajustar la velocidad y proporcione una tensión adecuada para la tira de pasta de hilada de queso. In order to know what the optimum tension is to roll a strip of cheese-shaped cheese ball or skein of cheese, tests must be carried out by varying the speeds of the roller motor 50, and the winding system, or, variable speed drives can be integrated to adjust the motor torque of 50 rollers and with this obtain an ideal speed producing a suitable tension to be able to roll a strip of cheese spinning paste. An output signal from load cell 150 can be used to indicate the increase in size and weight of the ball or skein of cheese, and according to that signal, the drive can adjust the speed and provide adequate tension for the strip of cheese spinning pasta.
Como se pretende que el peso que indique la celda de carga 150 esté relacionado con la tensión que debe de ir ajustando el variador de velocidad conforme aumente el peso, significa que el diámetro de la bola o madeja de queso también se ira incrementando. Entonces se puede realizar una relación de diámetro respecto al peso, aplicando la siguiente ecuación :
Figure imgf000014_0001
Since the weight indicated by the load cell 150 is intended to be related to the tension that the speed variator must adjust as the weight increases, it means that the diameter of the ball or skein of cheese will also increase.
