Description

one

The invention relates to instrumentation and mechanical engineering and can be used in software process control systems.

Known storage devices, camcorder camcorders and profile potentiometers of various designs, as carriers of information l3 .in

The known devices require the replacement of the information carrier — the profile cam, the potentiometer when switching from one nporpaMNttj to another, and this program control channel is switched off from work. In addition, they have limited accuracy in setting the program due to inaccuracy in the manufacture of parts, assembly, as a result of element wear, and temperature changes.

The closest in technical essence to the present invention is a memory device containing a drum with metal elements (plates) moving in the axial direction during recording and reading information of the inductive converter 2.

However, the known memory of the device is limited to 30

the complexity of the program due to inaccuracies in the manufacture and assembly of parts, changes in the parameters of the elements during operation, as the program is protected by continuously changing the position of the metal elements, and also requires considerable time when the program is changed manually when the linear parameter of loading is difficult to control.

The purpose of the invention is to improve the accuracy of continuous storage devices and reduce the time to reconfigure the task program.

The goal is achieved in that a second device connected to an asterisk located on the first shaft on which the transducer is installed is inserted into a memory device containing a drum, on which there is a second shaft, a gear transmission, an additional asterisk and additional sockets installed on the other end surface of the drum and associated with an additional sprocket mounted on the second shaft, located parallel to the first 1I gear connected to it.

The drawing shows a kinematic diagram of a memory device. .

The device contains shafts 1, 2. and 3, drum 4, metal elements (tsevki) 5, sprockets 6, 7, gears 8 and 9, the Converter 10,

The device works as follows.

On the drum 4, rigidly fixed on the shaft 1, metal elements (tsevki) 5 are mounted on the left and on the right side, which, when the shaft 1 rotates alternately (in accordance with the program), engages with the sprockets 6 and 7 and turns the shafts or 3 the angle defined by the gear ratio of these pin gears and the gearing module. When the shaft 3 rotates, the movement is transmitted to the shaft 2 through a gear pair 8 and 9. On the shaft 2, a transducer is fixed, for example, a rotor of a multi-turn potentiometer 10, which receives rotation in one direction or the other depending on the engagement of the left or right yoke. In the absence of bobbins on the right and left sides of the drum, the rotor of the potentiometer is stationary when the drum rotates. At the same time, the engagement of the left and right ends is eliminated by the task program. Thus, the discrete setting of the coils on the drum in accordance with the program allows, when the shaft rotates with the drum, to obtain a continuous (non-jump-like change in, for example, the electric resistance of the potentiometer) at the output of the converter.

The use of a storage device containing a drum with a discrete (ternary) program setting and pin assignment in the form of a reader, transforming the entire discrete task into a continuous functional relationship, allows for high-fidelity reproduction of the program, determined by the drum diameter, module and gear ratio transfer, little dependent on the accuracy of manufacture and assembly of elements, and the change in the program of the task, carried out by the installation of straps on the drum, Small time and convenient enough.
