The device works as follows.

2 $ The operator dials on the remote 3

required mark, which consists of several digits. Suppose that the mark is a nine-digit number (ten digits \

), for example, the batch number of the product - three digits, the product number - three digits, the date - three digits (the serial number of the month and the last digit of the year). The dialing order on the remote control

35 for the first product should be as follows: the number of the product that most often changes, the batch number and, in turn, the date.

For the second product, its number is dialed and, if necessary, the batch number remains the same. In the initial state, the first counter 4 is in the zero state.

Consequently, the first output of the distribution unit 14 is ready to transmit a pulse. When any information key of the control panel 3 is pressed, a code corresponding to the key pressed appears on its information output, and a corresponding signal appears at the other output, which is fed to the input of counter 4 and to the input of distribution block 14. Wherein

55 unit is added to counter 4. With

pressing the second key on the remote 3

device operation is repeated in the same way. And so on until

The mark is fully typed.

With the correct dialing at the pulse 3 output, a signal arises, which resets the counter 4 and sends the first trigger 10 through the OR 12 element. The trigger 10 unlocks the key element 19 and deconstructs the combining unit 15 on its second input. While the pulses from the output of the first sensor I clock signals through the open key element 19 are received in antiphase at the counting inputs of the second counter 5 and the third counter 6 through the element OR 13, acting as the address counter for memory block 16. The first pulse from the output of the key 19 adds one to counter 6, thereby increasing the address of the cell to which the following information is written by one. In the mode of recording information in the memory block 16, the trigger 11 is in such a state that its output signal sets the memory block 16 to the recording mode. Therefore, when adding a unit to the counter 6 in the memory block 16, information is recorded which is located at its information input, i.e. at the exit of the de-blocking block 15 of the union When the pulse at the output of the key 19 drops to one, one is added to the counter 5. Counter 5 performs a double function: after a predetermined number of pulses arriving at its input, returns trigger 10 to its initial state and controls the address of combining unit 15.

On the block 15 of the union receives the code with the output of the remote control 3. Therefore, changing the address of the unification unit 15, thereby connecting the various bits of the remote control 3 controls to the input of the memory block 16, and so on until the entire contents of the remote control 3 controls will not be recorded in the block 16 memory. After writing the first mark in the memory block 16, the operator dials the next number. If the next item has the same batch number and the date does not change, the operator simply dials the item number. Then the write operation in memory block 16 is repeated.

After entering all the necessary values of marks in the memory block 16, the operator can

By pressing the corresponding key on the remote control 3, display the contents of memory block 16 on the indicator matrix 9. The total 5 number of marks recorded in memory block 16 is equal to the number of items monitored simultaneously.

The parked device allows you to automatically stop the output of the recorded information from the memory block 16 immediately after the last mark is output, regardless of their total number. This is done as follows. When you press the output key on the corresponding output of the remote control 3, a signal is generated that starts the differentiation unit 18. When the differentiation unit 18 is triggered, a signal is generated at its output, which through the second element OR 13 adds one to counter 6, which acts as an address counter for memory block 16.

When adding a unit to the counter 6 ', the code of the number corresponding to the output of the combining unit 15 is located at the information input of the memory block 16, since the trigger 1.0 is at this time in the initial state (described above}. to be one that cannot be found "; there is not a single mark in one digit. Thus, at the moment of adding the unit to the third counter 6, the information input of the memory block 16 contains a code that has never been encountered before. Therefore, the next last The last digit of the last mark is written to a cell of memory 16, a code different from all the previous ones.When a pulse of a predetermined code arrives at the input of the selector 17. A signal is generated after a while the operator releases the information output key of the control panel 3 and the differentiation block 18 a signal occurs, which resets the counter 6 to the zero state and transfers the second trigger 11 to the one state. The output signal of the second trigger 11 switches the memory block 16 to the state tyvaniya and launches the second sensor 2 sinhrosigna1190344

$

catching through the first element OR 12, flips trigger 10, which. unlocks the key 19, and the pulses from the output of the first sensor I clock signals arrive at the inputs of the second and third counters 5 and 6 pulses.

The device operates in the same way as described when considering the mode of recording information in memory block 16, but the memory block 16 is in read mode. After a predetermined number of pulses, the counter 5 returns, the trigger 10 returns to its initial state, and the value of the first mark is output from the memory block 16, which through the decoder 8 enters the indicator matrix 9, i.e. The process of "imprinting" begins. of this sign on x-ray film. After some time, sufficient for “stamping” the mark on the X-ray film, the second sensor 2 of the sync pulses produces a second pulse, transferring the trigger 10 and increasing the contents of the counters 5 and 6. If it turns out that only one marking is recorded in the memory block 16 sign, then the selector I7 pulses with its output pulse returns the trigger 11 to its original state. In this case, the second sensor 2 of the sync signals is reset, and the memory unit 16 switches to the recording mode. If in the memory block 16 there is still a certain number of marks, then the output of their values continues until the code from which the pulse selector 17 is triggered occurs. After the markings are displayed on the indicator matrix 9, it may be necessary to display the same signs again (for example, when checking the same products, but in a different projection ^. In this case, just press the output key on the remote control 3 and the output process will repeat completely.

If you want to record new values of marks, you should make a general reset (not shown) and enter the information as described above. When working with this device, it may be possible that the stand on which the products for X-ray radiography are installed can be rotated, and in some cases this is unacceptable (determined by the x-ray mode) .. Then in the first case, the matrix with the number of digits is used as the indicator matrix 9 equal to the number of digits of the marks.

If the stand during X-ray control can not be rotated. then in each nest for the location of products its own indicator matrix 9 is fastened. Inputs are all: these matrices 9 are connected in parallel, and the decoder terminals 20 are connected to their control inputs. After each overflow of the counter 5 pulses, one is added to the counter 7 decoder 20 alternately switch indicator matrix 9.

The use of the invention allows to significantly increase the performance of the light labeling of X-ray films.
