Description

(54) DEVICE FOR METRAZH ACCOUNT AND DETERMINATION OF THE RETURN THEORETICAL WEIGHT

The code of the signal at the second input of the device selects the corresponding parameter of the output signal of block 6.

The device works as follows.

In the initial state, generator 5 and one-shot 3 are inhibited, keys 4 are closed, counter 2 is reset to zero.

Generator 5, depending on the input signal from block 6, produces at the output a burst of pulses including from 1 to 9 pulses. After the formation of the pulse packet has been completed, the generator 5 is reset. An external device connects to the three inputs of the device a length meter, information from which must be entered into the device. At the entrance

3, counter 2, with a parallel (or sequential) code, records information on a variable part of the length.

The information input 2 to the setting block 6 is supplied with a code corresponding to the value of the base length (constant part) of the connected length meter. Input 1 is given a command signal to start converting the base length code to a number.

With the arrival of the command signal, the first one-shot 3 is started, which for the duration of its pulse opens the key

4 and the leading edge acts on block 6. Depending on the code of the signal at input 2 of block 6, at its output, one of 9 signals will start, which will start generator 5, and the latter will form a burst. The pulses from the output of the generator 5 through the public key 4 will pass to the input of one of the decades of the counter 2. At this point, the process of recording one bit of information about the base length ends. The duration of the one-shot 3 is chosen such that during this time the generator 5 was able to generate at least 9 pulses. When the first one-shot returns to its initial state, the second one is started and, accordingly, the first key 4 is closed and the next one is opened. Depending on the code in block 6 for the second bit, generator 5 is started and the second bit value is written to counter 2. The processes are repeated for all bits.

As can be seen from the description of the operation of the device, with a 3-bit value of the number of base lengths in the proposed device, it is necessary to record a maximum of 9X3 27 pulses.

codes.

With each new connection, the product length information is summed up in counter 2 with the information of previous products.

The measurement result is transmitted to the output of the device for display, registration or for processing in a universal computer.

When determining the theoretical weight of products at input 2 in block 6, the weight code of the unit of the length of the product is supplied, and input 1 - the number of units of the length of the product. Otherwise, the operation of the device does not differ from that described above.
