Description

The cycle counter contains a decade counter of units 1 and a ten-decade counter of tens 2. The input of the counter of units 1 is connected via a functional device 3 with parallel switches 4 and 5, of which switch 5 serves for manual control of counters 1 and 2, and switch 4 contacts Follow the card of each group of punch cards. The counter of units 1 has ten output contacts (from O to 9), the number of each of which corresponds to the number of pulses received at the counter input within ten, as well as the output 6, the signal to which is given every ten pulses.

The output 6 of counter 1 is connected via functional device 7 to the input of counter tens 2. The latter also has ten outputs (from 0 to 9), the number of each of which corresponds to the number of tens of pulses at the input of counter 1, as well as output 8.

Meters I and 2 are powered through transformer 9.

There are also input contacts 10 and And, through diodes 12 and 13 connected to a switch 14, which is connected to an electromagnet 15, included in the circuit of switches 16 and 17, serving to set the meters 1 and 2 to zero. Switch 16 is in contact with a punch card map corresponding to the last row of the product. The switch 17 serves to manually set the zero.

The decimal outputs of counters 1 and 2 are connected to a coordinate distributor 18 consisting of two systems of perforated plates 19 and 20.

The plates 19 are connected to the inputs of the counter of units 1 and are located at the same level, and the plates 20 are connected to the outputs of the counter of tens 2. Each of the plates has ten holes, the holes of the plates 19 are coaxial with the holes of the plates 20 and their coordinates encode the number in the exact number system.

The distributor is equipped with pinch connectors 21 connecting one of the plates 19 to one of the plates 20, and the connection is made via a diode 22 mounted inside the plug 21. The output contact 8 of the counter 2 is connected to the terminal 23 of the actuator unit (see Fig. 4), containing four functional devices 24-27, of which devices 24, 25 and 26 carry out, for example, signal inversion and serve to communicate a chain of punched cards, respectively, two cards forward, one card back and two cards back. The device 27 serves to communicate a punch card of movement one card forward and is connected to terminal 23 via a diode 28.

The control device operates as follows.

The signal of the last card of each group of the punch card chain (not shown in Fig.) Switches 4 give a signal to the input of the unit counter 1 (see Fig. 1), connected to the power input of the counter 1 in series one

for another plate O-9 from the group of plates 19 of the coordinate distributor 18 (see Figs. 2, 3).

After every ten pulses supplied by the switch 4, a pulse is removed from the output 6 of the counter 1, which is transmitted to the input of the counter tens of 2, connected to its power input successively one after the other plates O-9 from the group of plates 20 of the distributor 18.

Diode tickers 21 are inserted into the holes of the plates 19 and 20, and the coordinates of the location of the plugs encode the number of cycles of movement of punch card groups (for example, 20, 26, 56, 69).

The signal of the first card of the group of punched cards includes a functional device 24, transmitting to the actuating element (not shown in Fig.) A command to move the chain of punched cards two cards forward.

The signal of the last card of this group of punch cards includes the device 25, which sends to the executive element a command to move the punch card chain one card back, and the signal of the next card includes

device 26 and move the punch card to two cards back until the first card of the group is reached.

Then the cycle is repeated. The number of repetitions of the cycle is marked with the help of a counter and, according to this number, the coordinates of the chucker 21 on the coordinate distributor 18 apply voltage to the output 8 of counter 2 and, thus, turn on the functional device 27 and lock the devices 24-26, blocking the signal supplied to them from chains of punched cards. At the same time, the movement of a punch card chain one card ahead and transfer to the next group of punch cards, providing the next section of the product.

At the command of the last card of the punch card circuit, the switch 16 is closed, the transfer of the counter to zero.

If necessary, the device is controlled manually by means of a switch 5 and the counter is set to zero by a switch 17.
