Position detection system and position detection method for tire building drum

Abstract

The invention discloses a position detection system and a position detection method for a tire building drum, and belongs to the technical field of tire building. The position detection system comprises two ranging components, a drive unit and a control unit, wherein the two ranging components are arranged at the radial outer side of the tire building drum, and radially aligned with support discson two anti-package rod assemblies separately; the drive unit is used for driving the synchronous opposite or reverse axial movement of the two ranging components; and the control unit is in signal connection with the drive unit and the tire building drum, and used for controlling the movement of the anti-package rod assemblies and controlling the working state of the drive unit. The position detection method is based on the position detection system, and used for carrying out position confirmation on the anti-package rod assemblies on the tire building drum. The drive unit is capable of driving the ranging components to detect at different positions, so that a more accurate detection result is achieved; and moreover, the movement distances of the two ranging components can be adjusted, then different tires are matched, and convenient adjustment is achieved.

Description

technical field [0001] The invention relates to the technical field of tire building, in particular to a position detection system and a position detection method for a tire building drum. Background technique [0002] At present, the tire building drum of the tire building machine includes a drum shaft and two half-drums axially spaced on the drum shaft. The half-drum includes a turn-up rod assembly, which includes several turn-up rods arranged around the drum axis. When the composite plies and plies of a tire are supplied to a carcass assembly forming a circumference on a tire building drum, two opposing beads are mounted axially spaced apart from the carcass assembly to form a Seal the space, while inflating the space between the two opposite beads, drive several turn-up rods on both sides to move relative to each other from the initial position, so as to turn up the composite layer and the ply on the axially outer side of the bead On the carcass assembly formed by infl...

AI Technical Summary

Problems solved by technology

[0003] During the turn-up process, if some turn-up rods cannot be turned up in place, the composite layer and ply on the axially outer side of the bead cannot be fully attached to the carcass assembly formed by inflation.

After the turn-up is completed, some turn-up rods cannot return to the initial position, which will cause the outer surface of the tire building drum to bulge, and when the tire building drum continues to rotate the material, it will cause the turn-up rods to swing or the rubber to bulge and break

Existing tire building drums often use pressure switches to detect the pressure value to determine whether the turn-up lever is back in place, but it cannot detect whether the turn-up lever is raised to the position, so it cannot be judged whether the turn-up action is normal, which may easily cause turn-up product failures

In addition, for tires of different specifications, when the tire parameters change, they cannot be switched freely, and the scope of use is limited
