Title: Ring spinner for ring spinning machine - has rapid coupling and uncoupling locks between ring and carrier rail for fast assembly and removal
Inventor: PROSINO CARLO ALBERTO
IPC: D01H7/64
Filed: 1992-04-14
Abstract: The ring spinner has rapid coupling and uncoupling components between the ring and the ring carrier rail. The ring is pref. fitted to a base unit on the ring carrier rail. The ring rail, with a further mounting, is fitted to the first base unit with the coupling/uncoupling unit between them. The coupling/uncoupling unit is of an elastomeric material, or of elastomeric components of the first base unit, is as a ring shape. The elastomeric ring is inserted into a seat in the first base unit, with a profiled inner cylindrical wall acting with matching profiled outer cylindrical walls of the second unit of the ring. The profiled inner wall of the elastomeric ring unit has a radially projecting lip acting with the radial expansion of the second unit, to give an elastic mounting at the first. An axial lock section bears against the second section when snapped together with the first. The ring section can also be an elastic O-ring inserted into a peripheral throat shaped for the outer cylindrical wall of the first base to act elastically with the second unit. The ring section can also be a coil spring wound round the ring as the rapid coupling/uncoupling unit. The couplings can also be a number of sprung balls in seatings to give a snap coupling and uncoupling by overcoming their spring pressures when inserted and removed. The radial position of the ring is adjusted between the first base unit and the ring carrier rail, through an auxiliary base fixed to the carrier rail to support the adjusters. Two circular rails, are at the ends of the ring so that the ring can be inverted with couplings at one rail to attach and dismantle the assembly at the carrier rail. A centre section has an outer ring beading to act with the coupling/uncoupling units. The material has a porosity to allow periodic impregnation with a lubricant. The assembly and dismantling is through a handgrip with a tapered end, and a stepped tooth, to separate the components for insertion and removal. ADVANTAGE - The structures gives rapid assembly and dismantling of the ring on the ring spinner.

The voltage or current measuring device is used as a sensor to ascertain whether the retraction drive of the electrodes have in fact separated them from the workpieces. The measuring voltage has a polarity which is opposite to the polarity of the rectifier voltage. At least one measuring lead (14, 15) is provided with an ohmic resistor (12). Such a resistor is located between the negative terminal of the voltage source (10) and the connection of the measuring device (11). USE/ADVANTGE - In welding equipment. It is inexpensive, and allows the contact between the workpieces and welding electrodes to be reliably determined.
