Description

one

The image is in the field of automation and can be used to record programs on a magnetic tape to control machine tools.

According to the main author. St. Jvfe 5О418О a device is known for recording a program on a magnetic tape containing an interpolator, the information outputs of which are connected via a converter of input pulses to a recording unit, a unit; inputs, triggers, AND elements, commutators, and a time reference block, zero and one trigger outputs are connected to the inputs of the AND elements, and according to the time reference block and directly. The output of the first element And is connected to the single and zero inputs of the respective / vents of the first and second triggers. The output of the second element I is connected to the single input of the trigger and the input of the input unit, the first output is connected to the zero input of the first trigger, and the inputs of the switch connected to the control inputs of the input pulse converter are connected to the zero output of the first trigger and the single output of the second trigger, connected to the second output of the input block.

However, the accuracy of the device and its reliability is insufficient. The aim of the invention is to improve the accuracy and reliability of the device.

The goal is achieved by the fact that three pulse formers, four

a trigger, an additional element AND and an OR element, the first input of which is connected to the first input of the mechanism for pulling a magnetic tape, through the first triggers connected in series, the first pulse shaper, the fourth trigger, the second pulse shaper to the second input of the mechanism for pulling the magnetic tape, through serially connected second trigger, up to

the complementary element AND, the fetium trigger and the third pulse shaper — to the first input of the input unit, the second input of which is connected to the output of the OR element, the first output to the zero input

the first trigger and the zero input of the four-point trigger, whose ernichny entrance is connected to the second input of the element or; the zero input of the second flip-flop and the first input of the converter of input s pulses, and the zero output connected via an electronic battery to the second input of the transducer of the input pulses. The zero output of the second trigger is sent to the block for setting the time to write commands.

In the drawing, 1h is the unit diagram of the device.

Device i input unit 1, int popor 2, converter of input is pulses 3, recording unit 4 on a magnetic tape, mechanism 5 dpa stretching magnetic tape 6, first 7, second 8, and third 9 triggers, grigs 1 11, fourth trigger 12, block 13 for setting command recording time, electronic switch 14, additional element 15, elements 16 and 17, 18, second 19 and third 20 pulse drivers, element OR 21, and button 22 Working stroke.

The device works as the next ofaz.

When the device blocks are turned on and the BUTTON 22 is pressed, the working stroke starts recording the command tape with the 6 pulses of the Play command received from the converter 3 into the .4 recording unit, as well as triggers 7 and 8, and through the element } 1t OR 21 pre-installed-35, the input unit 1 is poured. The% 1and pressing the button 22 switches the flip-flop 9, the shaper 19 is triggered, gives off a coma-v do Start into the input block 1 and the flip-flop 9 returns to its original state. At the same time, the input unit pushes the punched tape up to the beginning of the nepebix program frame and generates an error signal, under the action of which the previously cocked trigger 7 is switched, the FR-45 globalizer 18 is triggered and the input block is blocked. When triggered, the drivers 18, the signal from the output of the output, switches the 1st trigger 8, prepares the converter 3 for operation, cocks the trigger 12 and, through the element so OR 21 Lovgorno, restores the operating state of the input unit. The differential voltage at the zero output of the trigger 8 excites the time setting block 13, the differential of the single output prepares the working element 5 and 15. At the end of the time delay, the setting unit 13) triggers the signal and initiates the element 15

the pulse from the output of which switches the trigger 9. The voltage drop at the output of the trigger is converted by shaper 19 into a start command for the input block.

The codes read from the punched tape by the input block are converted in the interpolator 2, converter 3 and fed to block 4 for writing to the corresponding coordinate tracks of the magnetic tape.

In the last line of the pattern, the punchy tape breaks the end of the nporpa fm code. When the input block is read, it stops, issues a signal confirming the state of the trigger 8, and switches the trigger 12 previously routed by the signal from the imager 18.

The difference in voltage from the single output of the trigger 9 enters the driver 20, transforms into the Stop LMB command, extracts the tape drive mechanism 5 and stops the magnetic tape 6. if there is an error in the photomultiplier or if the frame is read incorrectly, the input unit also stops and generates an Error signal. The signal is schematically converted to the Stop LSM command and automatically interrupts the recording process. .

The proposed device optimally distributes the functions between the person and the machine and EXCLUDES the human subjective errors characteristic of the person, automatically controls the quality of the storage and stops the process when an objective error occurs or after completion of the recording, and possibly provides multi-machine maintenance. At the same time, the productivity of the recording of the program is increased by 30%,
