Definitions
- the object of the present invention refers, as its title indicates, to a pneumatic control ring applicable to ring twisting machines, continuous ring spinning machines and double twisting twisting machines, which by creating an air cushion between The ring and the thread and the lubrication of the contact surface between the two prevents the appearance of the balloon effect and that the wire is frictionally stripped against a surface that is the ball control ring, allowing higher process speeds.
- the pneumatic control ring consists of a ring of sintered material in the shape of a hollow cylinder, which is lubricated by a mixture of compressed air and lubricant from a External mixer, which in turn creates an "air mattress" between the ring and the thread.
- This ring in its outer part, has a groove that is the entrance to an internal chamber of the ring and is sealed and insulated from the outside by a joint, thus avoiding leaks that could occur.
- This chamber communicates with the outside exclusively through a cylindrical conduit that is the entrance of the air-lubricant mixture.
- the section also presents, in the part of the outer surface of the ring, where there is no contact between the ring and the thread, a layer of sealing varnish whose purpose is to prevent the exit of the air-lubricant mixture through this area.
- the air-lubricant mixture is introduced under pressure into the inner chamber of the pneumatic control ring thanks to the pressure of the air coming from external sources. This pressure forces the air-lubricant mixture to pass through the pores of the ring making a homogeneous and constant distribution of the lubricant in the ring-wire contact area.
- FIG. 1 Pneumatic control ring revolution section.
- the pneumatic control ring (1) consists of a ring of sintered material, preferably constructed of material of ferric, aluminum or plastic origin in the shape of a hollow cylinder.
- the pneumatic control ring (1) has a degree of porosity between 0.1% and 50% relative to the volume or total specific weight of the pneumatic control ring (1).
- the pneumatic control ring (1) has an internal chamber (4).
- This internal chamber (4) has at the end that coincides with the outer wall of the ring (1) and communicates with the outside a groove, which is covered by a gasket (2) preferably constituted of rubber, and pressed into said groove and whose purpose is to seal and isolate the internal chamber (4) from the outside to prevent leaks of the air-lubricant mixture, as well as possible pressure losses.
- Said internal chamber (4) communicates with the outside exclusively through a cylindrical duct (5) through which the air-lubricant mixture is introduced.
- the introduction of the air-lubricant mixture is achieved thanks to a fitting (3), preferably metallic, fixed to the cylindrical duct (5), which allows the connection of the internal chamber (4) with a tube (7) preferably made of plastic , which conducts the air-lubricant mixture with a given pressure and mixing ratio, from the mixer (8) to the fitting (3) and the cylindrical duct (5).
- the section of the pneumatic control ring (1) has a part of the outer surface of the ring (1) where there is no contact between the ring (1) and the thread, a layer of sealant varnish (6), the purpose of this layer of sealant varnish (6) is to prevent the exit of the air-lubricant mixture through this area and, consequently, avoid losses .
- the pressure of the air-lubricant mixture is due to the use of compressed air for its realization. This pressure is adjustable, being able to work with a pressure range between 0.2 bar and 80 bar.
- Mixing is done in an external mixer (8) to the pneumatic control ring (1).
- this mixer (8) the mixture is made between the lubricant, located in a tank (9), which can have a viscosity between 0.1 and 250 centistocks (measured at 40 ° C according to ISO standards), so as to allow a homogeneous and constant lubrication over time depending on the characteristics of the thread to be twisted and the porosity index of the ring (1), and the air from an external source (10) to the ring (1).
- This mixer (8) allows to adjust the proportion of the mixture in a range from 100% air and 0% lubricant to a mixture that is 0% air and 100%) of lubricant, depending on the characteristics of the thread and the ring material (1) with which it works.
- the introduction of the pressurized air-lubricant mixture, together with the porosity of the ring (1) allows the creation of an air mattress between the ring (1) and the thread, while the ring (1) distributes the mixture air-lubricant, allowing homogeneous and constant lubrication in time of the contact surface between the ring (1) and the thread, thus reducing the friction of the wire against the pneumatic control ring (1), allowing high working speeds
- the pneumatic control ring (1) moves with a vertical movement with respect to the machine, causing the control ring (1) to be positioned at the ideal distance between the thread guide and the bobbin for proper control of the ball in each winding moment.
