(54) PNEUMATIC DETACHING DEVICE

one

The invention relates to pneumatic automation devices and can be applied in monitoring and control systems.

Known pneumatic circumferential devices containing series-connected cells 1.

Each cell of this device includes three elements, which complicates its design.

The closest in technical essence to the present invention is a pneumatic enclosing device containing sequentially connected triggers with separate inputs, a channel of clock pulses and logic elements 2.

The presence of logical elements connected to each trigger, leads to large hardware costs.

The purpose of the invention is to reduce hardware costs.

This goal is achieved by the fact that, in a wrapping device that contains series-connected triggers with separate inputs, the outputs of which are connected to the output channels of the device, a channel of clock pulses connected directly to the first clock width and through the device switch to the second clock thickness, connected to the input of the first trigger, the power channels of the odd triggers are connected to the first clock band, and the power channels of the even triggers are connected to the second clock band.

The drawing shows the electrical circuit of the device.

The device can be used with triggers with separate inputs, in which power failure leads to the formation of a zero output signal.

As an example, the drawing shows the execution of triggers with separate inputs on multiple input membrane elements OR 1, 2, 3, ..., n, the output channel 4 of each of which is connected to the input 5 of the same element and to the input 6 of the next element in the chain. One of the inputs of the first element in the chain 1 is connected to the device enable channel 7, and the output of the last element in the chain n is connected to the input of element 1. The power supply channels 8 of the odd elements OR 1, 3, etc. are connected to the first clock width 9, and even with the second clock thickness 10, which through the element NOT 11 is connected to the channel of 12 clock pulses.

Pneumatic skimmer device works as follows.

Let the channel 12 fed zero clock signal, the input 7 - a single signal. Since the bus 9 is directly connected to the channel 12, zero pressure takes place in the feed channels 8 of the odd elements. Therefore, the output element

1 also a zero signal despite the fact that at its input 7 is a single signal. Even OR elements, etc., are under supply pressure, however, on the E-inputs of all (except the first) OR elements, there are zero signals, and, therefore, on all outputs 4 of the encircling device there are also zero signals. Suppose now that channel 12 receives a single clock signal. At the output of element 1, a single signal is generated. This signal is fed to the input 6 of element 2, but since the moment a single clock signal arrived, all even-numbered elements in the chain are de-energized and, therefore, the output of the element

2 - zero signal, despite the fact that at its input 6 - a single signal.

The next clock signal is zero. From the moment it enters, the odd elements become de-energized, and the even pressure receives the supply pressure from the NOT 11 element. Assuming that the input signal line 6 is emptying slower than the pressure builds up in the supply line 8 of the element 2, the output 4 of this element appears signal. This signal is fed to the input 5 of element 2 and, thus, is memorized by this element. The same single signal is fed to the input 6 of element 3, however, the element

3 by this time is already de-energized.

Further in a similar way all triggers of the device are sequentially triggered. Since the output of the element of the latter is connected to the input of element 1, then after the end of the first run-around cycle, the second and so on will follow.

The hardware costs of manufacturing the proposed devices are significantly lower than those of the known ones.
