DD158564A1 - OPTICAL SIGNALING OF WIRE STRIPS ON QUICK-SEALING MACHINES - Google Patents

Abstract

In known shutdown devices for Schnellverseilmaschinen an electrical contact is given via lever and this passed over lines to an electrical relay. In other devices, the wire itself is used as a contact and the contact time is extended with a sophisticated electronic circuit. The aim of the invention is to convey the signal to the switching relay of the fast stranding machine without the use of slip rings in a wire tear, the signaling from the interior of the stranding machine is to make the turn-off relay. This is achieved when, in the case of a wire tear, the short electrical signal is extended through a charge store and thus a cell is actuated, which reverses its reflectance from a nearly 1 to 0 signal. An externally arranged reflection barrier picks up this signal and transmits it back to a relay, which stops the high-speed stranding machine.

Title of the invention

Optical signaling of wire breaks on high-speed stranding machines

Field of application of the invention

Q5 The invention relates to an optical signaling of wire tears on high-speed stranding machines, in which mechanically generated, extremely short contact times are processed to useful, suitable for the switching of relay pulses · ¹

Characteristic of the known technical solutions

In the prior art shutdown devices for fast twisting machines are known which give a electrical Eontakt via a lever and pass it on lines to an electrical relay and thereby close or open a circuit, which in turn turns off the machine, Other devices use the wire itself as Contact and extend the contact time with a complex electronic circuit (WP 79 671) · All methods transmit the information on electrical cables, which must be made for special applications, such as, S, transmission from the interior of rotating machine parts, by multiple slip ring transmissions "Thus results in a high mechanical complexity with high space requirements and low reliability as well as a large number of switching devices and material in electronic circuits

Aim of the invention;

It is an object of the invention to eliminate the existing disadvantages au to transmit the signal to the switching relay of the Schnellverseilmaschine without using additional mechanical devices in a wire tear and to achieve higher precision and reliability and a saving of material »

Explanation of the essence of the invention

The invention is based on the object with a wire tear the signaling from the interior of the stranding machine to 4bschaltrelais without the aid of mechanical transmission elements ·

According to the invention, this object is achieved by the short electrical signal is extended by a "charge storage in a wire tear and thus a cell is controlled, which reverses its reflectance of almost 1- to O signal, outside arranged reflection barrier receives this signal, and transmits It is connected to a relay that stops the high-speed stranding machine by arranging a voltage source, a capacitor and a reflector-equipped cell within the yaw-line machine for detecting, transmitting and relaying the signal resulting from wire breakage.

Outside the fast stranding machine is a '> light source and a photoreceiver «

Furthermore, the invention provides that the voltage source is designed as a battery, Monazelle or photoelement »

The invention also includes a transverter, which is provided for generating the necessary operating voltage and which is designed as a mono-cell or photoelement when the voltage source is output.

If a wire break, an electrical signal is triggered in the interior of the stranding machine, which is connected by means of the leads 1 to the ² elle 3 and thus causes a opacity (dimming), d 'h · the beam path from the light source 4 to the photoreceptor interrupts. The interruption of the beam path follows via a switching relay immediately switching off the Schnellversilmaschine ο In a wire crack strikes the wire 9 against the contact device 10, wherein according to Fig * 2, the capacitor 7 is charged by the voltage of the battery 8 and thus the extremely short signal extended (stores) and transmits to the ^Z elle 3, so that the light beam 6 is interrupted by the cell 3 for a long enough time so that the switching relay can be operated to shut down the Schnellversilmaschine *
