Definitions
- the invention relates to a pressing device for tire building machines, comprising a pressure roller axis and a plurality of disc elements and at least one force application device for realizing a force on at least one of the disc elements.
- the manufacture of a tire for example for vehicles such as cars or motorcycles, is an extremely complex process that consists of a variety of manufacturing and process steps. The reason for this is the complicated tire structure consisting of a considerable number of different individual components. In addition, this variety of components under pressure and temperature, the so-called vulcanization must be connected to each other. Not only the finished tire as the end product of the tire manufacturing process, but also the green tire is a highly complex component consisting of many semifinished elements. Due to the multi-layered structure, the individual components must be assembled first and before a vulcanization process, ie the tire components are size separated and fed position, position, orientation exactly a carcass drum, which is located within a tire building machine. In this way, the green tire is prepared and prepared for vulcanization.
- tire components are designed as sheet and / or sheet semi-finished products: various rubber compounds and rubber-based composite materials, textile fabrics or textile cord, steel belt fabrics and rubber-coated bead cores.
- partial ply servers are used within a tire building machine.
- pressure rollers serve in particular within tire building machines for realizing a pressing force on the individual components, which are present as sheet-like or sheet-like materials or semi-finished products prior to the production step of the vulcanization and are combined to form a semi-finished tire within the tire building machine.
- individual components which are present as sheet-like or sheet-like materials or semi-finished products prior to the production step of the vulcanization and are combined to form a semi-finished tire within the tire building machine.
- core filler wedge strips, side strips and other elements may be pressed.
- pressure rollers are used for pressing, for example, web and sheet-like materials of the same and or different thickness, profiles and elasticities, which is initiated by an acting pressing force.
- This will be the geometric conditions of a pressure roller as a rotationally symmetric component following a surface pressure along a - comparatively to the diameter of the pressure roller narrow - applied linear contact surface.
- pressure rollers In order to provide pressure rollers, in particular in the context of tire building machines or for the tire manufacturing process, which enable either a uniform pressing force even with different thickness dimensions and, or profiled surfaces or specifically to produce locally different surface pressures, pressure rollers have been constructed whose cylindrical surface by a plurality of each other and in radial direction movable elements, so-called disc elements or ring elements are formed, which make it possible to adapt the surface contour of the pressure roller to the geometric conditions of the material to be pressed in terms of thickness and, or contour. In this way, the surface pressure along the contact line either evened or targeted a surface pressure gradient can be introduced.
- the disk elements are preferably mounted and functionally coupled such that, in addition to the radial mobility, there is at least one rotational degree of freedom with respect to the pressure roller axis.
- At least one or a group of disc elements with a defined force in Direction of the material to be pressed on causes on the one hand the radial component of movement of the disk element and on the other hand the resulting surface pressure acting on the material to be pressed by the disk element and the respective contact surface.
- Pressure rollers with a plurality of disc elements and the ability to apply the defined force for each individual disc element by means of suitable, separate force application devices have the advantage that locally different surface pressures can be introduced into the pressure material and / or very accurately adjustable surface pressure gradients can be realized over the contact line.
- pressure rollers in this constructive design have high costs due to the complicated structure and the large number of force application devices required and are both prone to failure and maintenance-intensive.
- the teaching of the invention recognizes that these goals can be achieved by a clever combination of Kraftbeetzschlagungs foundeden for individual and group-wise disk elements. Furthermore, the invention proposes to improve the deformation rigidity of the pressure roller local and releasable connection techniques.
- the invention reduces the design effort and simultaneously increases the deformation stiffness by a combination of individual and group summarized kraftbeetzschlagbaren disc elements.
- the areas of the semi-finished tire web, which make locally high or changed surface pressures required with a pressure roller constructed in accordance with the invention, comprising different zones equipped with disc elements, pressed, which are each kraftbeaufschlagbar individually or in groups.
- Such areas are present in conventional tire structures especially at the transition points of tire walls and tire tread areas. Special or particularly pronounced profile geometries on the tire tread may also require special surface pressure values.
- the invention provides that at least two zones are realized within a pressure roller.
- a first zone is formed by one or a plurality of disc elements, which opens the possibility by at least one Kraftbeaufschlagungs worn, each act on a single disc element with a definable force.
- the second zone is formed by a plurality of disc elements, which opens the possibility by at least one force application device to apply the plurality of disc elements as a group together with a definable force.
- a group ie a plurality of disk elements
- it is intended to realize the force application device by means of an elastic pressure hose which is pressurized by means of a compressible medium and the group of disks benimplantationn uniformly subjected to force, which is supported by the resulting radial displaceability of each disc element in this zone area a uniform surface pressure along the linear contact surface of the pressure roller zone and semi-finished tire web.
- pressure rollers which have more than two zones.
- Semi-finished tire webs are typically three-stranded across their web width following the later shape of the finished tire, with the two web outer strands representing the sidewalls of the tire and the center strand representing the tire tread.
- the teaching of the invention therefore provides, in one embodiment, pressure rollers for use in tire building machines which have at least three zones.
- the three pressure roller zones can each have the same or differing force application devices, with at least both equal and unequal forces being adjustable in magnitude.
- the invention recognizes further advantages through the use of further zones in the pressure roller assembly.
- the outer, ie the side walls of the finished tire forming strands have significantly thinner wall thicknesses, as the tire tread forming the center strand.
- the transition regions of the strands to each other are therefore characterized by significant thickness jumps, which often make a special expression of the surface pressure gradient required to achieve optimal connection results of the web layers.
- the invention provides five-zone pressure roller assemblies, i. at the level of the strand transition areas, in addition to the zones for the sidewalls and the tread of the later tire, zones are provided which support these particular manifestations of the surface pressure gradient.
- the respective zones in the strand transition regions can be subdivided once again and also repeatedly into zones in order to be able to initiate even more precise surface pressures at specific points in the tire semi-finished product web. It is intended to provide pressure rollers which have up to eleven zones.
- the force application devices can be provided either outside or inside the pressure roller.
- the disc elements are preferably subjected to force, via contact means, opposite the contact surface between the pressure roller and the web material, without their rotational degree of freedom being restricted.
- the disk elements are preferably on the inside and facing the contact surface between the pressure roller and the Web material force applied via contact means, which also leave the rotational degree of freedom of the disc elements untouched.
- the invention provides for the arrangement of the force application devices within the pressure roller.
- the axis of the pressure roller is preferably formed as a center of rotation for the disk elements at least partially by the Kraftbe aufschlagungs Sken or their elements.
- the arrangement of the Kraftbeaufschlagungs arise at least in the areas of the adjacent zones and, or individual Kraftbeaufschlagungs noticeden to each other contact points that must be connected in a suitable manner and preferably releasably in order to fulfill the function as Andrückrollenachse.
- the pressure roller axis must be designed so that the highest possible bending stiffness is supported.
- the invention provides the right-angled or quadrangular cross-sectional configuration of the pressure roller axis in order to advantageously utilize the deformation resistance, in particular bending, which is very high as a result of the resultant structural strength.
- the rectangular cross section is provided and aligned relative to the main load direction such that the longer side edges lie parallel to the resultant force action line.
- the invention provides at the parallel to the resultant line of action side edges of rectangular or square Andrückrollenachsen in the areas of the contact points of the adjacent zones and, or individual Kraftbeaufschlagungsurbanen each other before annular grooves into which reinforcing rings can be inserted.
- the flexural rigidity is improved even if it is a clearance of the joining partners.
- the improvements, ie reduction of deformation under load, can be up to a factor of 6 compared to non-reinforcing connection techniques by the reinforcing rings inserted with clearance fit into the annular grooves.
- connection partners at the contact point are radially displacing the joining partners relative to one another about the play's displacement path.
- the connection partners with their front shoulders on each other and force and form fit of the reinforcing ring is set within the annular groove, resulting from the then present favorable spacing ratios of the neutral phase compared to the highly loaded tensile / pressure areas in the edge regions of Andrückrollenachse considerably reduced Voltage peaks and a deviating from the rectangular orientation of the resulting stress tensor.

- FIG. 7 shows a further exemplary embodiment of the pressure roller axle (110) with different zones and annular groove reinforcement ring connections in a three-dimensional representation.
- Zones Z1 to Z5 are matched in their position and training on the preferably three strands of the tire semi-finished product track and their transition areas and equipped with suitable Kraftbeierschlagungs drivingen (120, 121, 122). Zones Z1 and Z5 are opposite the outer strands, i. the later side walls of the finished tire arranged.
