Description

Tire inflation equipment

Technical Field

The invention relates to the field of tire processing, in particular to tire inflation equipment.

Background

In automated mass production processes, motor vehicle wheels with tubeless tires are typically inflated with compressed air in an automated tire inflation station integrated on an assembly line. In this case, the rim with the assembled tire is placed on a suitable base plate, which seals the wheel downward during inflation. On the upper side of the tire, an inflation cap is placed, which seals the tire and the rim on the top and thus presses the tire sidewall so far down during inflation that an annular gap is formed between the tire rim and the rim, through which gap compressed air introduced into the inflation cap can flow into the tire. The tire is pressed against the support plate and the inflation cover with a large force by the inflow of compressed air. If the inflation pressure is sufficient, the inflation hood is raised, as a result of which the tire sidewalls move relative to one another in the axial direction until the tire rim enters the respective mounting position on the rim.

The storage magazine frame and the gas-filled plate can be moved relative to one another in the direction of the axis of rotation into a plurality of delivery positions in which the storage magazine guides are each connected to a gas-filled plate guide arranged on the gas-filled plate. The inflation ring located in the magazine guide disposed at the delivery location can be transferred into the inflation panel guide and into the central position of the inflation panel by means of a transfer device.
