Description

one

The invention relates to the field of machinery.

Known devices for storing the quantity of the mantle tape remaining on the "coil of the current node of the tape mech-gz: magnetic tape, do not allow the counting to be performed with a sufficient degree of accuracy.

In order to increase the accuracy of counting the remaining Magnetic Tape, the proposed device is equipped with a dual resistive divider connected to the power supply and relay contacts, its control unit, connected to different inputs of the dual-decoupling counter.

The drawing is an electrical block diagram of the Label of the device for instrumentation (number of magnetic tape.

The double bypass mechanism 1 relocates the magnetic tape 2 placed on the rollers 3} 4 of the corresponding tank assemblies. Directly from the lateral side assembly (-on the drawing, not inoiKaaaai) for the sensor 5, and the number of the past tape, connected to the distributor 6 pulses. In the device, units of measurement of stock of magnetic tape and control 8 are used. Between the sensor 5 and the tape mechanism / power source 9 is turned on, the driver 6 through the frequency divider 10 soadinea with a binary reversing counter //, made with decades, 12, 13, 14. Some of the inputs of the counter are connected via buses 15, 16 to contacts 17, 18, 19 of relay 20 of control unit 8. Pushing iKOiiTaiKT 19, in turn, is connected to a dual unit: a divider consisting of single dividers 21 and 22. Others the inputs of the counter through the bus 23 are connected to stroystvom initial ycTancBiKij counter 24 //. Tires 25, 26, 27 are output, and blocks 28, 29, and 30 are) 13 decoders, which are connected to digital signals 31, 32, 33.

In the process of moving the tape, the cut-and-cut sensor closes. which allows the former 6 to forge pulses. The division factor of frequency divider 10 is determined by the conversion factor 5. The selection of the counter operation mode // occurs automatically with the help of relay 20. When the tape moves from the coil of the feeding unit, the meter works on subtraction, and when the tape moves from the pick-up coil to addition. Simultaneously with measuring the stock of the tape, the measurement results are converted; rhenium into a digital code of a binary-decimal type, which, with buses 25, 26, 27, goes to

the required object, iiainipiiiMep to the sensing machine.
