Description

The invention relates to the field of production control and can be used to control, for example, knitting machines, both in industry and in everyday life.

Known control devices for knitting machines with row counters of a mechanical type [1].

The closest analogue is the knitting machine control device described in [2], which contains software storage device and data storage device connected to a recording / reading device, a calculator, as well as display elements and a keyboard as a control element. The program is entered into the software memory either at the time of manufacture or from a stationary computer. Such a device does not have the ability to directly receive data from a controlled machine, or directly control the engine of the machine, as well as the ability to manually change the program.

The objective of the invention is to provide a simple device for controlling production processes with the possibility of direct interaction with a controlled machine.

The task in the control device containing a software storage device (memory), a data storage device (memory) associated with a recording / reading device, a calculator, display elements and a keyboard, is solved by the fact that it is equipped with a sensor for communication with a controlled device, programmable reversible a counter, a code converter, a shift register, a starter for turning the controlled engine on / off and an additional keyboard for recording / correcting programs, the sensor output being connected to the main input of a programmable reversible counter, the outputs of which are connected directly with the first input of the code converter, with its second input through the shift register, with the third input through the computer, and the fourth and fifth inputs of the code converter are connected to the corresponding outputs of the recording / reading device connected by the first, second and the third information outputs with control inputs, and the first, second and third information inputs with signal outputs of a reversible counter, a shift register and the calculator, respectively, the fourth information input with an additional keyboard, and the control input with the first keyboard, and the outputs of the code converter are connected to the display elements, and the control output of the shift register is connected to the starter.

The calculator can be made in the form of an arithmetic adder.

In addition, the display elements are made in the form of a series of individual indicators.

The drawing shows a block diagram of an example implementation of the inventive device for controlling a knitting machine.

The control device comprises a sensor 1 for communication with a controlled device - a knitting machine, a programmable reversible counter 2, a shift register 3, an arithmetic adder 4, a code converter 5, and also a software memory 6 and data memory 7. All of these elements are connected by their control inputs with information outputs, and their signal outputs - with the information inputs of the device 8 write / read. The outputs of the code converter 5 are connected to the display elements: the first output is with the indicator 9 of the number of passes made by the knitting machine, the second with the indicator 10 of the next stop number of the machine, the third with indicator 11 of the total number of passes of the machine during the execution of the program, the fourth with indicator 1 2 directions of the account, and the fifth - with the indicator 1 3 numbers of the executable program. The first keyboard 1 4 is designed to control operating modes and intermediate (emergency) engine stop / start, it is connected to the control input of the device 8 write / read. An additional keyboard 15 is intended for recording / correction of programs and is associated with the fourth information output of the device 8 recording / reading. To the output of the shift register 3 is connected starter 1 6 to turn on / off the controlled motor M.

The inventive device when controlling the operation of the knitting machine operates as follows.

In preparation for work in the recording / correction mode of the program using the first keyboard 1 4, the device 8 recording / reading is transferred to the recording / correction program. At this time, the signal of the device 8 through the shift register 3 blocks the starter 1 6, which stops the engine M. Then, using the keyboard 1 5 through the device 8 write / read in the software memory 6, sequentially, with an indication on the corresponding indicators, information is recorded about the program number , the number of stops of the engine M of the knitting machine during the execution of this program, and the number of times the carriage of the knitting machine passed before each stop. In this case, the indicator 1 0 indicates the serial number of the next engine stop, and indicator 9 indicates the number of passes of the machine before this stop. At the same time, the scoreboard 11 shows the total number of passes of the machine in this program, and the indicator 1 2 indicates the count direction of the programmable reversible counter 2 3 “forward” - with increasing or “back” - with decreasing. At the end of the recording / correction of the program from the keyboard 14, a signal is sent to the recording / reading device 8, which blocks its fourth information input associated with the keyboard 15.

In operating mode, each passage of the carriage of the knitting machine is recorded by sensor 1 and read by counter 2, from where it goes to indicator 9 through the code converter 5. Indicator 10 indicates the number of the next stop of the machine, and indicator 11 indicates the total number of passes made with the “forward” count or the number of failed passes at the account "back". When the counter 2 reaches the number of passes recorded in the program memory 6, the shift register 3 is triggered, and, upon a signal from its output, starter 1 6 stops engine M.

After the necessary manipulations with a controlled machine (not shown), for example, replacing a colored thread, counter 2 and register 3 are activated from the first keyboard 1 4 through the write / read device 8 and the engine is switched on via the starter 1 6.

If unscheduled correction is necessary, the engine is also stopped through the keyboard 1 4.
