Polea de cristal para un banco de estirajeGlass pulley for a stretching bench
La invencion se refiere a una polea de cristal para un banco de estiraje que se puede fijar de manera montable y amovible en un bastidor de maquina mediante una unidad de montaje en un lado, pudiendo accionarse la polea de cristal mediante un accionamiento independiente, de acuerdo con el preambulo de la reivindicacion 1.The invention relates to a glass pulley for a stretching bench that can be mounted movably and removably in a machine frame by means of a mounting unit on one side, the glass pulley being able to be operated by an independent drive, according to with the preamble of claim 1.
De acuerdo con el estado de la tecnica, trabajos de mantenimiento en el banco de estiraje son muy complejos, ya que, en primer lugar, se desmonta la polea de cristal y, a continuacion, todos los elementos del montaje de polea de cristal se tienen que retirar individualmente del bastidor de maquina. En poleas de cristal que estan dispuestas en la zona de un bano qulmico, existe siempre el riesgo de que elementos de union o componentes constructivos caigan al interior del bano y los montadores se expongan de forma excesiva al llquido qulmico. Dado que a este respecto solo se puede trabajar con mucha prudencia, aumenta el tiempo de mantenimiento y, con ello, el tiempo de parada.According to the state of the art, maintenance work on the stretch bench is very complex, since, first, the glass pulley is disassembled and then all the elements of the glass pulley assembly are to be removed individually from the machine frame. In glass pulleys that are arranged in the area of a chemical bath, there is always a risk that union elements or construction components will fall inside the bath and the assemblers will be excessively exposed to the chemical liquid. Since in this respect you can only work very cautiously, the maintenance time and, thus, the downtime increases.
En el documento EP 0940488 A1 se describe una polea de cristal calentable para el procesamiento de hilo que se acciona con un accionamiento de rueda de friccion mediante un arbol de accionamiento utilizado para todas las poleas de cristal. Un arbol comun lleva en un extremo la polea de cristal y en el otro extremo el accionamiento de rueda de friccion que se coloca con un ajuste de presion. Mediante un tornillo se puede retirar la polea de cristal de la unidad de calefaccion, permaneciendo la unidad de montaje en un brazo articulado. Un desmontaje completo de la polea de cristal incluyendo la unidad de montaje implica mucho trabajo con esta construccion.EP 0940488 A1 describes a heated glass pulley for wire processing which is driven by a friction wheel drive by means of a drive shaft used for all glass pulleys. A common shaft carries at one end the glass pulley and at the other end the friction wheel drive that is placed with a pressure adjustment. Using a screw, the glass pulley can be removed from the heating unit, the assembly unit remaining on an articulated arm. A complete disassembly of the glass pulley including the assembly unit involves a lot of work with this construction.
El documento DE 2354147 A1 muestra tambien una polea de cristal calentada que esta dispuesta con un accionamiento en cada caso sobre un extremo opuesto de un arbol comun. La polea de cristal se puede desmontar del reborde de arbol conico tras la liberacion de un tornillo, permaneciendo el arbol con los cojinetes en la carcasa. El motor esta zunchado sobre el gorron del arbol y no se puede desmontar con medios sencillos. Tampoco esta construccion preve un desmontaje rapido y completo de la polea de cristal con la unidad de montaje.Document DE 2354147 A1 also shows a heated glass pulley that is arranged with a drive in each case on an opposite end of a common tree. The glass pulley can be removed from the conical tree flange after the release of a screw, the tree remaining with the bearings in the housing. The engine is stuck on the tree's cap and cannot be disassembled with simple means. Nor does this construction provide for rapid and complete disassembly of the glass pulley with the assembly unit.
El documento JP2008262926 muestra una polea de cristal calentada que esta fijada con un munon escalonado en un bastidor de maquina. El motor esta dispuesto sobre un arbol que esta integrado dentro del munon. Un desmontaje de la polea de cristal incluyendo la unidad de montaje es solo posible cuando el motor se ha desmontado completamente del arbol.JP2008262926 shows a heated glass pulley that is fixed with a staggered munon in a machine frame. The engine is arranged on a tree that is integrated into the world.

Con las caracterlsticas de la invencion es posible desmontar con pocas maniobras las poleas de cristal con la unidad de montaje completamente del bastidor de maquina y mantener toda la unidad en condiciones de taller. En la practica, una carretilla elevadora absorbera el peso de la polea de cristal y extraera la polea de cristal con la unidad de montaje del bastidor de maquina tras la liberacion de los elementos de fijacion.The fixing and assembly of the glass pulley are designed so that, after the release of the assembly unit of the machine frame and the decoupling of the drive, the glass pulley including the assembly unit can be disassembled from the machine frame . With the characteristics of the invention it is possible to disassemble the glass pulleys with a few maneuvers with the assembly unit completely from the machine frame and keep the whole unit in workshop conditions. In practice, a forklift will absorb the weight of the glass pulley and remove the glass pulley with the assembly unit of the machine frame after the release of the fixing elements.
A este respecto, la unidad de montaje comprende un munon, unos cojinetes primero y segundo, un casquillo de cojinete y una brida. Con ello, la unidad de montaje se puede montar como grupo constructivo completo en el bastidor de maquina, lo que facilita el montaje/desmontaje de la unidad de montaje en un cambio de los sellos o de las poleas de cristal.In this regard, the mounting unit comprises a munon, first and second bearings, a bearing bushing and a flange. With this, the assembly unit can be mounted as a complete construction group in the machine frame, which facilitates the assembly / disassembly of the assembly unit in a change of the glass seals or pulleys.
Mediante la brida, que se puede fijar en una pared anterior del bastidor de maquina, se puede realizar exclusivamente la fijacion de la unidad de montaje en el bastidor de maquina. A este respecto, el munon esta insertado en el accionamiento que se puede fijar en una pared posterior del bastidor de maquina. Con ello, la unidad de montaje se fija en la pared anterior del bastidor de maquina, y a traves de un orificio en la pared posterior se apoya y se sujeta por el accionamiento. El accionamiento puede estar unido exclusivamente mediante un soporte de par de giro con el bastidor de maquina.By means of the flange, which can be fixed on an anterior wall of the machine frame, the mounting unit can only be fixed on the machine frame. In this regard, the munon is inserted into the drive that can be fixed on a rear wall of the machine frame. With this, the mounting unit is fixed on the front wall of the machine frame, and through a hole in the rear wall it is supported and held by the drive. The drive can be connected exclusively by means of a torque support with the machine frame.
Una mejora adicional se puede conseguir cuando el munon esta unido de manera amovible con la polea de cristal. De este modo, por ejemplo, la polea de cristal se puede fabricar a partir de un acero resistente frente a corrosion uAn additional improvement can be achieved when the munon is removably attached to the glass pulley. Thus, for example, the glass pulley can be manufactured from a corrosion resistant steel or

otra aleacion especial qulmicamente resistente, mientras que el munon se puede fabricar al menos en su mayor parte a partir de un material economico normal tal como, por ejemplo, un acero de carbono. Esto ahorra costes enormes con las dimensiones grandes de las poleas de cristal y de la unidad de montaje.another chemically resistant special alloy, while the munon can be manufactured at least for the most part from a normal economic material such as, for example, a carbon steel. This saves huge costs with the large dimensions of the glass pulleys and the mounting unit.
En una forma de realizacion ventajosa, un primer sello protege la unidad de montaje frente a influencias qulmicas. A este respecto, este montaje esta disenado de modo que, en el caso de un calentamiento del munon, este se puede expandir longitudinalmente.In an advantageous embodiment, a first seal protects the mounting unit against chemical influences. In this respect, this assembly is designed so that, in the case of a heating of the munon, it can be expanded longitudinally.
De manera correspondiente esta dispuesto un sello entre la brida y la pared anterior del bastidor de maquina. Ambos sellos realizan que los pocos componentes constructivos expuestos se tengan que fabricar a partir de un material de alta calidad, pudiendo fabricarse los componentes constructivos dispuestos dentro del bastidor de maquina y sellados hacia fuera a partir de un material mas economico.Correspondingly, a seal is arranged between the flange and the front wall of the machine frame. Both seals make the few exposed construction components have to be manufactured from a high quality material, being able to manufacture the construction components arranged inside the machine frame and sealed out from a more economical material.
Debido al hecho de que la polea de cristal incluyendo la unidad de montaje se puede extraer desde el lado de trabajo del bastidor de maquina, se puede realizar un cambio rapido de las poleas de cristal o un remplazamiento de los sellos mediante una liberacion de la brida y un desacoplamiento del accionamiento con ayuda, por ejemplo, de una carretilla elevadora u otro medio de absorcion de carga. De este modo se aumenta claramente la disponibilidad de la instalacion.Due to the fact that the glass pulley including the mounting unit can be removed from the working side of the machine frame, a quick change of the glass pulleys or a replacement of the seals can be made by a release of the flange and a decoupling of the drive with the help, for example, of a forklift or other means of load absorption. This clearly increases the availability of the installation.

Las poleas de cristal 5a a 5e o 6a a 6e estan dispuestas en el lado anterior de un bastidor de maquina 7, 8, teniendo cada polea de cristal 5a a 5e o 6a a 6e un accionamiento propio que se puede regular independientemente de los otros accionamientos. El montaje de las poleas de cristal 5a a 5e o 6a a 6e se realiza como montaje unilateral o en voladizo dentro del bastidor de maquina 7, 8. En el lado posterior del bastidor de maquina 7, 8 estan fijados los accionamientos de las poleas de cristal 5a a 5e o 6a a 6e. Por encima de cada unidad de polea de cristal 2a, 2b esta dispuesto al menos un rodillo de contacto 9, 10 que exprime llquido de bano excedente, por ejemplo, de las poleas de cristal 5a o 6a.In figure 1 a stretching bench 1 is shown that has two glass pulley units 2a, 2b, and a bath 3 disposed therebetween with a unit 4 in which a pump, a tank and pipes for the bath are arranged 3. In this embodiment, each glass pulley unit 2a, 2b has two upper glass pulleys 5a, 5b or 6a, 6b and three lower glass pulleys 5c, 5d, 5e or 6c, 6d, 6e that are arranged displaced from each other. The glass pulleys 5e, 6c, which are arranged towards the bath 3, are at least partially submerged in the bath 3. The glass pulleys 5a to 5e or 6a to 6e are arranged on the front side of a machine frame 7 , 8, each glass pulley having 5a to 5e or 6a to 6e having its own drive that can be regulated independently of the other drives. The assembly of the glass pulleys 5a to 5e or 6a to 6e is carried out as a unilateral or cantilever assembly inside the machine frame 7, 8. On the rear side of the machine frame 7, 8 the drives of the pulleys are fixed. crystal 5th to 5th or 6th to 6th. Above each glass pulley unit 2a, 2b there is at least one contact roller 9, 10 that squeezes excess bath liquid, for example, from the glass pulleys 5a or 6a.
El montaje de las poleas de cristal se describe mediante la figura 2. En esta figura se representa la polea de cristal 6b que esta unida mediante una unidad de montaje con un accionamiento 11. Por un lado, el accionamiento 11 esta fijado en el bastidor de maquina 8 mediante un soporte de par de giro 12. Por otro lado, se realiza una union mediante un gorron de accionamiento 20 con la polea de cristal 6b. Entre el gorron de accionamiento 20 y la polea de cristal 6b esta dispuesto un munon 13 que se monta mediante unos cojinetes primero y segundo 14, 15 en el bastidor de maquina 8. En este ejemplo de realizacion, el munon 13 esta disenado de manera conica para alojar cojinetes 14, 15 de un tamano diferente. El primer cojinete 14, que esta dispuesto en la zona de la pared anterior 8a del bastidor de maquina 8 y tiene que absorber las fuerzas mayores, tiene un diametro mayor que el segundo cojinete 15 que esta dispuesto en la zona de la pared posterior 8b del bastidor de maquina 8. La fijacion del primer cojinete 14 en el bastidor de maquina 8 se realiza mediante una brida 18 que esta fijada mediante elementos de union 17 en la pared anterior 8a del bastidor de maquina 8. El segundo cojinete 15 esta dispuesto dentro de un casquillo de cojinete 16 que se extiende desde la pared posterior 8b del bastidor de maquina 8 hasta la brida 18. La unidad de montaje esta configurada como denominado cartucho y, con ello, comprende el munon 13, los cojinetes primero y segundo 14, 15, el casquillo de cojinete 16 y la brida 18 y el primer sello 19.The assembly of the glass pulleys is described by figure 2. This figure shows the glass pulley 6b which is connected by a mounting unit with a drive 11. On the one hand, the drive 11 is fixed on the frame of machine 8 by means of a torque support 12. On the other hand, a connection is made by means of a drive pin 20 with the glass pulley 6b. Between the drive cap 20 and the glass pulley 6b a munon 13 is disposed that is mounted by first and second bearings 14, 15 on the machine frame 8. In this exemplary embodiment, the munon 13 is conically designed to accommodate bearings 14, 15 of a different size. The first bearing 14, which is arranged in the area of the anterior wall 8a of the machine frame 8 and has to absorb the major forces, has a diameter larger than the second bearing 15 which is arranged in the area of the rear wall 8b of the machine frame 8. The fixing of the first bearing 14 on the machine frame 8 is carried out by means of a flange 18 which is fixed by means of joining elements 17 on the front wall 8a of the machine frame 8. The second bearing 15 is disposed within a bearing bushing 16 extending from the rear wall 8b of the machine frame 8 to the flange 18. The mounting unit is configured as a cartridge and thus comprises the munon 13, the first and second bearings 14, 15 , the bearing bushing 16 and the flange 18 and the first seal 19.
La polea de cristal 6b esta fijada con un lado frontal en el munon 13. En esta representacion, el lado frontal opuesto se representa abierto, ya que la tapa frontal, que se puede apreciar en la figura 1, se retiro. Con ello, la polea de cristal 6b tiene la forma de un casquillo, en el que la base del casquillo se atornilla con el munon 13. El lado frontal de casquillo, que en la figura 2 es abierto, se cierra mediante una tapa no representada en esta figura. El soporte de la polea de cristal 6b se protege mediante un primer sello 19 frente a las influencias qulmicas del llquido de bano. El segundo sello se realiza entre la brida 18 y la pared anterior del bastidor de maquina 8.The glass pulley 6b is fixed with a front side on the munon 13. In this representation, the opposite front side is shown open, since the front cover, which can be seen in Figure 1, is removed. With this, the glass pulley 6b has the form of a bushing, in which the base of the bushing is screwed with the munon 13. The front bushing side, which in figure 2 is opened, is closed by a cover not shown in this figure. The support of the glass pulley 6b is protected by a first seal 19 against the chemical influences of the bath liquid. The second seal is made between the flange 18 and the front wall of the machine frame 8.
El desmontaje de toda la polea de cristal 6b incluyendo el montaje se realiza desmontando el accionamiento 11. Tras la liberacion de los elementos de union 17, toda la polea de cristal 6b incluyendo los cojinetes 14, 15, el gorron 13 y el casquillo de cojinete 16 se puede retirar desde el lado de trabajo del bastidor de maquina 8. Con ello, es posible remplazar toda la polea de cristal 6b incluyendo la unidad de montaje y realizar trabajos de mantenimiento en condiciones de taller. Con ello, los tiempos de parada de toda la instalacion se pueden reducir claramente, ya que, en comparacion con el estado de la tecnica, no se tiene que descomponer la instalacion global.Disassembly of the entire glass pulley 6b including assembly is carried out by disassembling the drive 11. After the release of the connecting elements 17, the entire glass pulley 6b including the bearings 14, 15, the journal 13 and the bearing bushing 16 can be removed from the working side of the machine frame 8. With this, it is possible to replace the entire glass pulley 6b including the assembly unit and perform maintenance work in workshop conditions. With this, the downtimes of the entire installation can be clearly reduced, since, in comparison with the state of the art, the global installation does not have to be decomposed.

Debido al sellado de los cojinetes 14, 15, cada polea de cristal se puede sumergir en parte o completamente en el llquido del bano 3. Debido al desmontaje sencillo de toda la polea de cristal incluyendo la unidad de montaje, los sellos se pueden remplazar de manera muy sencilla. Solo la polea de cristal con los elementos dispuestos en la pared anterior 8a del bastidor de maquina 8 tal como, por ejemplo, los elementos de union 17, la brida 18 y la zona del primer sellado 19 se tiene que fabricar a partir de material resistente frente a la corrosion. El casquillo de cojinete 16 y los elementos adicionales dispuestos dentro del bastidor de maquina 8 se pueden fabricar a partir de materiales mas economicos, ya que estos no entran en contacto con el llquido, dado el caso agresivo, del bano 3.Due to the sealing of the bearings 14, 15, each glass pulley can be partially or completely submerged in the liquid of the bath 3. Due to the simple disassembly of the entire glass pulley including the mounting unit, the seals can be replaced with very simple way. Only the glass pulley with the elements arranged in the front wall 8a of the machine frame 8 such as, for example, the joining elements 17, the flange 18 and the area of the first seal 19 has to be manufactured from resistant material against corrosion. The bearing bushing 16 and the additional elements arranged inside the machine frame 8 can be manufactured from more economical materials, since these do not come into contact with the liquid, in the aggressive case, of the bath 3.
