Embodiment Construction

[0015] like figure 1 As shown, a cleaning device, designated generally by the reference numeral 1 , is provided in the tire curing mold 2 . The mould 2 includes a plurality of microvalves 3 arranged on the entire inner surface 4 thereof.

[0016] like figure 2 Shown in more detail, the device includes a camera 5 for detecting each microvalve 3 . The camera 5 is associated with an algorithm of the "Hough Circle Transform" type via a computer (not shown). The algorithm can perform a complete reading of the inner surface 4 of the mold 2 . The camera 5 is illuminated by a light source 6 of LED type. The device further comprises an ultrasonic pen 7 mounted on a track 8 for gradually bringing the pen into contact with the microvalve and an accelerometer 9 for detecting changes in frequency indicating the end of cleaning of the microvalve . Instead of an accelerometer, a microphone could be used, which would be used to record changes in vibration frequency by clicking.

Abstract

The invention relates to a method for separating elastomeric particles attached to microvalves (3) arranged on the inner surface of a vehicle tyre vulcanisation mould (2). The method is characterized by: detecting the presence of a microvalve (3) provided on said inner surface of the mould; during separation of particles from the microvalve (3), the microvalve (3) is vibrated at a constant amplitude of between about 0.05 mm and 0.2 mm and a frequency of between 20000 Hz and 30000 Hz.

Description

technical field [0001] The present invention relates to a method for separating elastomer particles adhering to the surface of a microvalve provided on the inner surface of a tire vulcanization mold. Background technique [0002] From application WO 2016 / 105306, a method for cleaning microvalves of tire vulcanization moulds is known, the method comprising subjecting all moulds in a dry state to ultrasonic waves before cleaning them, then rinsing and drying all moulds Immerse in cleaning solution. This also results in a potentially long period of disassembly and unavailability of the mold and incompatibility with industry requirements. [0003] Unfortunately, this method is complicated due to the number of steps and the long execution time. Furthermore, this method does not allow targeted cleaning of the valve, and therefore a possible careful cleaning of the valve. [0004] Therefore, there remains a need for a method that enables targeted inspection of the interior regio...
