Description

[0001] Method and apparatus for producing a non-pneumatic tire

[0002] The invention relates to a method for producing a non-pneumatic tire. Furthermore, the invention relates to an apparatus for producing a non-pneumatic tire.

[0003] Concepts for airless tires, also called non-pneumatic tires, are known for commercial vehicles, such as small excavators, and consumer goods, such as lawn mowers, strollers, etc. Airless refers to the tire not being filled with compressed air. There are now also considerations for using airless tires in motor vehicles, such as passenger cars.

[0004] In non-pneumatic tires, the air chamber is usually replaced by specially shaped plastic spokes with open spaces between them. One advantage of non-pneumatic tires (NPTs) is that such tires cannot lose pressure, as there is no air chamber that can be damaged and / or is filled with compressed air. Furthermore, an airless tire has comparatively few components and can therefore be easily retreaded and disposed of or recycled after its useful life.

[0005] For example, from document EP 3 071 424 B1 a non-pneumatic tire is known having a support structure comprising an outer reinforced annular band, a hub and a set of stress-transmitting elements extending between the hub and radially inwardly from the outer reinforced annular band.

[0006] Furthermore, document US 2009 / 0211689 A1 discloses a device for vulcanizing tires, comprising a chamber 10 for accommodating a tire assembly 50, a heat exchanger 20 connected to the chamber 10, a heating unit 30 for heating water for the heat exchanger 20, and a pump 40 for circulating a water flow between the heating unit 30 and the heat exchanger 20. The chamber 10 is designed as a tire vulcanizing press, and the heat exchanger 20 has a heating bladder that can be arranged inside a tire cavity. Furthermore, a circuit is provided for directing the water flow through sections of the vulcanizing press that surround the exterior of the tire.

[0007] Conventional non-pneumatic tires can exhibit adverse behavior if contaminants, such as stones or ice in winter, accumulate in the openings between the spokes. The materials used can also exhibit material changes after years of exposure to UV light or numerous other environmental influences common in road use, such as heat or cold, or even solvents or cleaning agents. Such material changes can negatively impact the tire's performance. Furthermore, current manufacturing processes do not allow for a marketable cost profile, as the components must largely be manufactured in separate steps and then finally joined. This is complex, requires space-intensive logistics processes, and is very costly.

[0008] The invention is based on the object of functionally improving a method for producing a non-pneumatic tire mentioned above. Furthermore, the invention is based on the object of structurally and / or functionally improving a device for producing a non-pneumatic tire mentioned above. Therefore, it is an object of the present invention to provide a method and a device that reduce or eliminate the problems identified in connection with the prior art. In particular, it is an object of the present invention to reduce the effort and achieve a high level of vertical integration. Furthermore, time- and space-intensive logistics and process sequences are to be reduced or completely eliminated.

[0009] The problem is solved by a method having the features of claim 1. Furthermore, the problem is solved by a device having the features of claim 19. Advantageous embodiments and / or further developments are the subject of the dependent claims, the description, and / or the accompanying figures. In particular, the independent claims of one claim category can also be developed and / or combined analogously to the dependent claims of another claim category. Likewise, the device and method features described below can be combined and / or further developed with one another.

[0010] One aspect relates to a method for manufacturing a non-pneumatic tire. The tire may be an airless tire. The tire may be a vehicle tire, such as a motor vehicle tire. The tire may have a tread, such as a tire tread. The tread may have an outer side and an inner side opposite the outer side. A radially outer surface, such as an outer surface, may be provided on the outer side. An outer tread portion may be provided on the outer side. The tread portion may be radially outer. The outer surface and / or the tread portion may form a running surface of the tire, such as a tire tread, on which the tire rolls during operation. The outer surface and / or the tread portion and / or the running surface may have and / or form a complete or incomplete profile, or no profile at all, such as a tire tread.The tread may have grooves, such as longitudinal grooves and / or transverse grooves. A radially inner surface, such as an inner surface, may be provided on the inner side. An inner tread portion may be provided on the inner side. The tread may be or be made from several different layers and / or materials. The materials may be rubber or rubber materials or rubber or rubber compounds. The tread may be a semi-finished product. The tread may be a multi-layer tread. The tread may be or have multi-layer tire tread. Terms such as “inner,” “outer,” “radial,” and “circumferential” may refer to the axis of rotation of the tire.

[0011] The method can comprise the step of providing the tread substantially in ring form within a mold. The mold can be a tire mold. The tread can be shaped or bent into a ring and then introduced, e.g. inserted, into the mold, for example into a cavity of the mold. The tread can be inserted in a ring shape into the mold or into the cavity of the mold. The tread can be made or will be made, at least in sections, from a rubber material. For example, the tread can be made, e.g. extruded, using an extrusion system. The tread can be made before the tread is provided, in particular before the tread is inserted into the mold.

[0012] A reinforcement layer can be or will be attached to the inside of the tread. The reinforcement layer can be or will be attached to the inner wheel section. The reinforcement layer can be a metal-reinforced layer, such as a rubber or elastomer layer. The reinforcement layer can comprise metal fibers or a metal mesh. The metal fibers or the metal mesh can be or will be impregnated with rubber or an elastomer. The metal can be steel. An adhesion promoter can be or will be applied to the inside of the tread or wheel section or to the inside of the reinforcement layer. Additionally or alternatively, polar or non-polar materials can be used and / or applied. This can set or achieve sufficient adhesion between these materials. The use of an adhesion promoter can then be omitted.

[0013] The method can comprise the step of pressing the tread, in particular its outer side, against a forming surface, such as a shaping surface, of the forming tool. In doing so, the outer surface and / or the tread section and / or the tread of the tread can be pressed against the forming surface of the forming tool. The forming surface and / or the cavity can be substantially annular. By pressing the tread, in particular its outer side, against the forming surface of the forming tool, a profile surface, in particular a tire profile, can be created. The forming surface can be a contoured surface and / or have a profile complementary to a tire profile, so that when the tread is pressed against the forming surface, the tire profile is formed in the tread. Pressing can also be understood as pressing. The pressing or pressing can be carried out using a hydraulic and / or pneumatic tool.The hydraulic and / or pneumatic tool can be or have a pressing tool and / or a hydraulically and / or pneumatically actuated bellows, such as a folding bellows. The hydraulic and / or pneumatic tool can be introduced, such as retracted or pivoted, at least in sections into the molding tool or its cavity, in particular before the pressing or pressing process. The hydraulic and / or pneumatic tool can be introduced, such as retracted or pivoted, at least in sections into the cavity delimited by the tread, in particular before the pressing or pressing process. The cavity delimited by the tread can be the area extending radially inward from the inside of the tread. By actuating the hydraulic and / or pneumatic tool, the tread, in particular its outer side, can be pressed, in particular pressed, against the molding surface of the molding tool.

[0014] The mold and / or its molding surface can be heated. The mold can be heated using a heating device. A predefined temperature level can be maintained or the temperature can be variably adjusted.

[0015] The method can comprise the step of introducing a temporarily heat-emitting mass into the cavity defined by the tread. The introduction can be by filling, injecting, or pouring. The cavity defined by the tread can be completely or partially filled with the mass. The cavity defined by the tread can be the air space of the tire. The air space of the tire can be completely or partially filled with the mass. The mass can be designed to temporarily release heat. The mass can cool down during this process. The heat released by the mass introduced into the cavity can cause or at least initiate vulcanization of at least one section, such as a rubber section, of the tread. Vulcanization can be the vulcanization of a rubber of the tread, in particular to form rubber.

[0016] The heat-dissipating mass can be a reactive mixture consisting of at least two reactive components. The reactive mixture can be a polyurethane reactive mixture. The at least two reactive components can be polyol and isocyanate. The reactive mixture can be a foam mixture, such as a plastic foam mixture. The reactive mixture can be based on polyurethane (PUR). The reactive mixture can form a foam, in particular a solid foam, for example plastic foam or polyurethane foam. The heat-dissipating mass, in particular the reactive mixture, can be introduced into the cavity defined by the tread by means of a mixing head, for example, injected or poured. The mixing head can be a low-pressure or high-pressure mixing head. The mold can be or can be coupled to the mixing head.The mixing head can be moved, introduced and / or pivoted into the mold cavity by means of a movement device, such as a robot or robot arm, and / or at least partially into the mold cavity. The mixing head can have a nozzle unit for discharging the reaction mixture. The at least two reactive components can be introduced, for example metered, into the mixing head. The at least two reactive components can be mixed with one another in the mixing head, in particular to form the reactive mixture. The reactive mixture can be produced and / or generated by means of the mixing head. The mixing head can be part of a reaction casting system. The reactive mixture can cause an exothermic reaction. The reactive mixture can temporarily release heat, such as reaction heat. The reaction mixture can harden, in particular to form a foam. The hardening can be caused by the reaction and / or occur with the release of heat.The vulcanization of at least one section, such as the rubber section, of the tread can take place or at least be initiated by means of the temperature of the mold and / or by means of the exothermic energy or the heat released by the reaction and / or polymerization reaction of the reactive mixture. The reaction and / or polymerization process of the reactive mixture can take place or be initiated simultaneously or in an overlapping manner. A temperature level can be maintained or variably adjusted, in particular until the reaction and / or polymerization process of the reactive mixture and / or the vulcanization is complete. An exothermic level or a specific heat release of the reaction and / or polymerization reaction of the reactive mixture can be maintained and / or the reaction and / or polymerization process of the reactive mixture can take place until the vulcanization is complete. The heat-emitting mass can be a melt.The melt can be a plastic melt. The melt can be produced and / or generated using an injection molding machine. The heat-emitting mass, in particular the melt, can be introduced, for example injected, into the cavity defined by the tread by means of an injection unit of the injection molding machine. The injection unit can be an injection and closing unit. The mold can be coupled to the injection unit or to the injection and closing unit of the injection molding machine. The melt can be brought to a specific temperature, such as melt temperature, by means of the injection molding machine. The vulcanization of at least one section, such as the rubber section, of the tread can take place or at least be initiated by means of the melt temperature and / or the heat release from the melt.The melt temperature can be maintained above the mold temperature, for example, until vulcanization is complete. Melt cooling and vulcanization can occur simultaneously or overlap. The melt can solidify, particularly with the release of heat.

[0017] At least one support structure, such as an insert, can be introduced into the cavity defined by the tread, particularly additionally. The support structure can be introduced before the heat-dissipating mass is introduced. The support structure can be composed of several struts. The support structure can be made of plastic and / or metal.

[0018] After completion of the polymerization, solidification, or vulcanization process, at least one post-processing step may be performed. The at least one post-processing step may include removing the tire from the mold, deburring, tempering, or the like.

[0019] Another aspect relates to an apparatus for producing a non-pneumatic tire. The tire may have a tread, such as a tire tread. The tread may have an outer side and an inner side opposite the outer side. The tire and / or the tread may be configured or become configured as described above and / or below. The apparatus may be configured and / or intended to carry out the method described above and / or below for producing the non-pneumatic tire.

[0020] The device may comprise a mold. The mold may be a tire mold. The mold may be a press, such as a tire press, e.g., a tire curing press. The mold may be a vulcanizing device. The mold may have a molding surface, such as a shaping surface, for molding the tread, in particular the outer surface of the tread. The mold may have a cavity. The molding surface may be arranged in the cavity and / or delimit it. The molding surface and / or the cavity may be substantially annular, circular, and / or cylindrical. The molding surface may be a contoured surface. The molding surface may have a profile complementary to a tire tread.

[0021] The device may comprise a heating device for heating the mold and / or the mold surface. The heating device may be configured to maintain a predefined temperature level or to variably adjust the temperature.

[0022] The device can comprise a hydraulic and / or pneumatic tool. The hydraulic and / or pneumatic tool can be designed to be inserted at least partially into the molding tool. The hydraulic and / or pneumatic tool can be designed to press, in particular to press, the tread, in particular its outer side, against the molding surface of the molding tool. The hydraulic and / or pneumatic tool can be or comprise a pressing tool and / or a hydraulically and / or pneumatically actuated bellows, such as a bellows.

[0023] The device can have a mixing head or a reaction casting system with a mixing head for introducing the heat-emitting mass, in particular the reaction mixture, into the cavity defined by the tread. The mixing head can be a low-pressure or high-pressure mixing head. The mold can be coupled to the mixing head. The device can have a movement device, such as a robot or robot arm. The movement device can be coupled to the mixing head. The movement device can be designed to move or insert and / or pivot the mixing head toward and / or at least partially into the cavity of the mold. The mixing head can have a nozzle unit for discharging the reaction mixture.

[0024] The device may comprise an injection unit or injection and closing unit for introducing the heat-emitting mass, in particular the melt, into the cavity defined by the tread. The device may comprise an injection molding machine with an injection unit or injection and closing unit for introducing the heat-emitting mass, in particular the melt, into the cavity defined by the tread. The mold may be coupled to the injection unit or to the injection and closing unit of the injection molding machine.

[0025] In summary, and in other words, the invention thus provides, among other things, a method and apparatus for producing airless vehicle tires. Highly integrated production can be provided, in which there is, in particular, only one upstream step for the production and, if necessary, conditioning of a semi-finished product, such as a tread. The semi-finished product can then be inserted into a subsequent process. From then on, all further process steps can, in principle, take place in a variable cavity. A reactive "RPM" process route or a thermoplastic "IMM" process route can be provided. Both process routes can begin with the production of a tread, such as a tire tread. SteelcordZ fabric-reinforced rubber or elastomer can then be added or applied to the underside of the tread. The tread surface, however, may not yet have a complete profile.Only the longitudinal grooves can be incorporated. The multi-layer tire profile, such as a tread, can now be conditioned on the inside as a semi-finished product for the subsequent steps, if necessary applying a bonding agent, and then inserted in a ring shape into the cavity of a mold. Depending on the design of the system, process and tool, either the RPM or the IMM process route can be provided. In a first sub-step, an upper tool part can be inserted, which presses the tread against a correspondingly contoured outer side of the tool in the lower part via a liquid- or gas-actuated, e.g. pneumatic, bellows, and thus inserts the future tire profile. After this process step, the upper tool part can be retracted and another one is inserted, which can then initiate the RPM or IMM process route, depending on the design.In the RPM process variant, a suitable reaction technology system based on the low-pressure or high-pressure principle can be connected to the tool, such as a mold. The components involved can be mixed in a mixing head and introduced into the cavity. The process parameters can be selected so that the mold temperature and the exothermicity of the polymerization reaction can be used to simultaneously or overlappingly initiate the reaction-polymerization process of the reactive mixture and the vulcanization of the rubber into the rubber. This temperature level can then be maintained or can be varied until polymerization and vulcanization are complete.

[0026] For example, in the RPM process variant, the mold profile can be created using a pneumatic bellows, then the polyurethane mixture (PUR) is poured in, and the temperature of the mold and the exothermic reaction can be used to cure the polyurethane mixture and to initiate or start the vulcanization process. The exothermic level can be maintained until vulcanization is complete. In the IMM process variant, the mold can be coupled with a corresponding injection and clamping unit, and the melt can be introduced into the cavity. Here, the melt temperature can be used to first introduce the melt and initiate the vulcanization of the rubber into the rubber. The temperature profile can then be selected so that melt cooling and vulcanization can take place simultaneously or overlappingly.For example, in the IMM process variant, the mold profile can be created using a pneumatic bellows, then melt is injected, and the melt temperature is used to initiate vulcanization. The melt temperature can be kept above the temperature level of the mold until vulcanization is complete. If necessary, support structures such as inserts or similar can be introduced into both process routes using appropriate automation. After completion of the polymerization, solidification, and / or vulcanization step, post-processing steps such as deburring, tempering, etc. can be performed. Additional effects can be achieved through chemical processes. For example, polar or non-polar materials can be used. The adhesion promoters often used to achieve sufficient adhesion between these materials can then be omitted if necessary.

[0027] The invention makes it possible to simplify process technology and the process sequence, in particular by utilizing the properties of one process step to initiate or facilitate the subsequent one. A high degree of integration can be enabled. Time- and / or space-intensive logistics processes or compensation steps can be eliminated. A high level of vertical integration can be achieved at the same production site. A complete production cell can have a small footprint compared to the vertical integration. Intermediate process steps such as balancing or compensation for shrinkage, for example by adding additional material in RPM processes or by pressing in IMM processes, can be integrated. Costs can be reduced. The material properties of the airless tire can be optimally adjusted or adapted.

[0028] In the following, embodiments of the invention are described in more detail with reference to figures, which show schematically and by way of example:

[0029] Fig. 1 shows an apparatus and a method according to an RPM process variant; and

[0030] Fig. 2 shows an apparatus and a method according to an IMM process variant.

[0031] Fig. 1 schematically shows a device 100 and a method according to an RPM process variant. The device 100 is designed to produce a non-pneumatic tire 102. The tire 102 comprises a tread 104 or is produced therefrom. The tread 104 can be a semi-finished product produced by means of an extrusion system (not shown in Fig. 1) or can be produced with the extrusion system. The tread 104 can be or can be made entirely or at least partially from rubber material. The tread 104 has an outer side / surface 106 and an inner side / surface 108 opposite the outer side 106. The device 100 has a mold 110 designed as a tire molding tool with a molding surface 112, which is arranged in a cavity of the mold 110.The molding surface 112 is designed for molding the tread 104, in particular the outer surface 106 of the tread 104, and for this purpose has a contoured surface and / or a profile complementary to a tire tread pattern. Furthermore, the device 100 has a heating device (not shown in Fig. 1) for heating the molding tool 110 or the molding surface 112.

[0032] Furthermore, the device 100 comprises a hydraulic and / or pneumatic tool 114, which can be introduced at least partially into the molding tool 110 or into the cavity of the molding tool 110 and is designed to press or press the tread 104, in particular its outer side / surface 106, against the molding surface 112 of the molding tool 110. The hydraulic and / or pneumatic tool 114 can be a hydraulically and / or pneumatically actuated bellows, which is initially inserted into the cavity of the molding tool 110 without pressure and then, by applying pressure, presses the tread 104 radially outward against the molding surface 112 in order to embed the tire profile into the tread 104.

[0033] In the present embodiment, the device 100 has a mixing head 116 configured to introduce, inject, or pour a heat-dissipating mass into the cavity 118 defined by the tread 104. The mixing head 116 can be a low-pressure or high-pressure mixing head. The heat-dissipating mass is a reactive mixture 120 consisting of at least two reactive components 122, 124, such as polyol and isocyanate, in particular a polyurethane reactive mixture.

[0034] Before the actual RPM process route begins, a reinforcement layer, in particular a metal-reinforced rubber or elastomer layer, can be applied to the inner side / surface 108 of the tread 104. Furthermore, an adhesion promoter can be applied to the inner side / surface 108 of the tread 104 or to an inner side of the reinforcement layer. The tread 104 is then provided or inserted essentially in a ring shape within the mold 110. The hydraulic and / or pneumatic tool 114 is then at least partially inserted into the cavity 108 defined by the tread 104. Then, by actuating the tool 114, the tread, in particular its outer side / surface 106, is pressed or compressed radially outward against the mold surface 112 of the mold 110, thereby creating the tire profile in the tread 104. The mold 110 can be heated by means of the heating device.

[0035] The heat-emitting mass or the reaction mixture 120 generated in the mixing head 116 is then introduced, injected, or poured into the cavity 118 delimited by the tread 104. The heat emitted by the reaction mixture 120 introduced into the cavity 118 causes vulcanization of at least one rubber section of the tread 104 to occur, or is at least initiated or started with the emitted heat. For example, the temperature of the mold 110 set by the heating device and the exothermicity or heat release of the reaction or polymerization reaction of the reactive mixture 120 can cause vulcanization of at least one section of the tread 104 to occur, or at least be initiated or started. The reaction and / or polymerization process of the reactive mixture 120 can occur, or at least be initiated, simultaneously or in an overlapping manner.A temperature level can be maintained or variably adjusted until the reaction and / or polymerization process of the reactive mixture 120 and / or the vulcanization is complete. For example, an exothermic level of the reaction and / or polymerization reaction of the reactive mixture 120 can be maintained and the reaction and / or polymerization process of the reactive mixture 120 can continue until the vulcanization is complete.

[0036] Meanwhile, the reactive mixture 120 introduced into the cavity 118 hardens into a foam 126, such as polyurethane foam, and bonds with the annular tread 104, thereby forming the airless tire 102.

[0037] Fig. 2 schematically shows a device 200 and a method according to an IMM process variant. In contrast to the device 100 according to Fig. 1, the device 200 has an injection unit 202 of an injection molding machine (not shown in Fig. 2) instead of the mixing head 116. The injection unit 202 can be designed as an injection and clamping unit. The injection unit 202 is coupled to the mold 110 or will be coupled thereto. The injection unit 202 is designed to introduce a heat-emitting mass, in particular a melt 204, into the cavity 118 delimited by the tread 104. The melt 204 is a plastic melt 204 plasticized by means of the injection unit 202 or the injection molding machine.

[0038] In the present exemplary embodiment, instead of the reaction mixture 102, the plastic melt 204 is introduced or injected into the cavity 118 defined by the tread 104 by means of the injection unit 202. Vulcanization of at least one section, such as the rubber section, of the tread 104 is effected by means of the melt temperature or is at least initiated or started by the heat emitted by the plastic melt 204. The melt temperature can be maintained, in particular above the temperature of the mold 110, until vulcanization is complete. Melt cooling and vulcanization can occur simultaneously or overlap.

[0039] Meanwhile, the plastic melt 204 introduced into the cavity 118 solidifies into a solid plastic material 206 and bonds with the annular tread 104, thereby forming the airless tire 102.

[0040] Furthermore, reference is made in particular to Fig. 1 and the associated description.

[0041] "May" refers in particular to optional features of the invention. Accordingly, there are also further developments and / or embodiments of the invention that additionally or alternatively comprise the respective feature(s).

[0042] If necessary, isolated features can also be extracted from the combinations of features disclosed here and used in combination with other features to define the subject matter of the claim, dissolving any structural and / or functional relationship between the features. The order and / or number of steps of the process can be varied. The processes and / or steps can be combined.
