Tire Building Machines in Tire Assembly

Method for producing vehicle tires with improved efficiency and reduced complexity compared to conventional tire manufacturing methods. The method involves separately building the tire carcass on a drum, removing it, and then expanding and connecting the sidewalls onto the carcass on separate drums before transferring it to the final drum for shaping. This allows building the carcass and sidewalls separately and connecting them later, avoiding the need for complex carcass building drums. The steps are: finish carcass, remove, expand sidewall drums, transfer carcass, expand sidewalls, transfer again, shape final tire.

Folding up the outer tire components onto a cambered tire carcass on a tire building drum using external roller levers and drives instead of internal bellows or side levers. This avoids the need for internal bellows or levers that wear out and require rework. The roller levers are moved radially by external drives to fold up the outer tire sections onto the cambered carcass. Then a continuous rolling process turns the folded sections inside out onto the carcass using turnover rollers. This allows simple and reliable folding of the outer tire sections onto the cambered carcass without internal mechanisms.

Turning up the sidewalls of a tire during the building process to prevent issues with side bellows and roller levers. The method involves expanding the tire carcass on a drum, folding the sidewalls up using radial-moving levers covered in stretchable material, and rolling them firmly onto the carcass. The covered levers and stretchable material provide even tension as the sidewalls are turned inside out and attached to the carcass. This avoids issues with side bellows not reaching the shoulders and uneven contact pressure with roller levers.

Machine for automated manufacture of biased crown tires with improved performance. The machine has a shaping system to expand the carcass body radially, a biasing system to interconnect the carcass and crown plies during shaping, and control to coordinate crown and carcass production. The biasing alters carcass orientation in the overlap area to create a biased crown. This allows radial carcass sidewalls with an oblique intersecting carcass in the crown.

A method for producing vehicle tires using a tire building drum to avoid cord deflection in the tire carcass. The method involves rolling the tire components onto the drum as usual, but then stopping the drum rotation and applying pressure to the tire with a roller. This compresses the tire sections against the drum surface, forming a wave-shaped deformation. The roller is then rotated to transfer the compressed shape to the adjacent section. This prevents carcass cord deflection by counteracting the pressure force with an oblique counterforce. After completing the drum winding, the tire is cured and finished.

Automatic assembly line for heavy commercial vehicle tires that uses robots and conveyors to automate tire assembly on large trucks. The line has pre-tightening stations, tightening stations, and manual stations on both sides of the main conveyor. Robots with grippers pre-tighten the nuts on the tires, then another robot tightens them fully. This allows automated assembly of heavy truck tires that are too large and heavy for manual installation.

Dual tire component feeding system for improving tire quality by precisely aligning the leading and trailing edges of dual tire components when they are placed on the tire building drum. The system has two independent pick-and-place units that can move laterally to adjust the edge alignment. Sensors detect the component position on the conveyor and drum. A control unit coordinates the pick-and-place movements based on the sensor signals. This allows compensating for component shifting during transport and joining the edges accurately.

A giant tire building machine with six drums arranged in two stages to improve efficiency and reduce labor compared to multi-drum machines. The machine has separate track assemblies for carcass and belt layer formation. The carcass assembly is transferred between drums using a ring. This allows sequential carcass building without moving steps. The belts are added in a separate track. After winding, the tire rotates 180 degrees for symmetrical grooving. This eliminates intermediate transfers and simplifies the process.

Tire building apparatus that allows adjusting the height of semi-finished tires wound around the drum in different directions to prevent gaps and sagging during molding. The apparatus has joints that move vertically along the drum circumference and width. The joints have elevating members and molding joints with attachments for the tires. The molding joints can have coupling parts that engage adjacent joints to prevent gaps. This allows adjusting tire height in both directions while preventing sagging and gaps at the ends.

A linear tire assembly line for efficient and compact tire assembly in a production line. The line has four stations arranged in a straight line, with clamping frames and clamping heads at the first three stations. The tire loading mechanism, inflation mechanism, and transmission drive are between the frames. The clamping heads secure the hub and tire. The linear layout allows moving the hub and tire between stations using progressive clamping. This saves space compared to rotating tables. A controller coordinates the clamping, loading, and inflation steps.

Three-in-one automatic tire loading machine that reduces labor, improves efficiency, and allows simultaneous multi-process operation compared to manual tire assembly. The machine has stations for valve nut assembly, tire casing assembly, and inner tube inflation aligned on a moving conveyor frame. This allows tires to be loaded with all steps done simultaneously instead of sequentially. The conveyor moves the tires between stations as each assembly is performed. This eliminates manual handling and waiting time between steps.

Tire building machine that can be converted between two common tire building methods without needing two separate machines. The machine has a take-up shaft for receiving the tire building drum. The first drum is for the shoulder method and the second drum is for the flat drum method. The drums can be swapped individually without the other drum. This allows the machine to produce tires using either the shoulder or flat drum method.

A cost-effective tire assembly machine for 4S shops that simplifies tire mounting without the need for expensive assembly lines. The machine has a sliding support module with a stepper motor that moves a rotating spline. The spline connects to a pneumatic gripper on one side and a fixed frame on the other. This allows the gripper to slide and rotate while holding the tire. The machine also has an extruding module that slides up and down to push the tire onto the wheel rim. The sliding support and extruding modules enable tire mounting without complex automated systems.

A method and apparatus for manufacturing tires that allows consistent and efficient production of tires with improved quality. The method involves using a dedicated turn-up drum with driven fingers to create uniform turn-ups on the tire blanks. This is different from the prior art where turn-ups are formed during tire building. The turn-up drum has spindles outside the main drum that drive the turn-up fingers. This provides symmetric motion for consistent turn-ups. The turn-up length is adjusted to flatten the blank for better load transfer. The method allows using flat building or crown building techniques.

Automated method and machine for manufacturing SOT green tires with high turnup plies. The machine allows fully automated production of SOT green tires with at least one high turnup ply. It uses a split tire building drum with movable halves, a core clamping device, turn-up bladders, sidewall servers, and a radial expandable middle section. The steps involve placing plies, expanding the middle, installing cores, turning up plies, transferring sidewall material to drum halves, moving halves under the core, pressing sidewalls, and introducing air. This allows building high turnup plies that overlap the sidewalls to reinforce them without covering the middle.
