Abstract

The invention relates to the field of mechanical engineering, in particular, to the design of control systems for the operation of equipment for pressure treatment. The aim of the invention is to expand the technological capabilities by ensuring control of the tolerance for the length of the feed material in both directions from a given value, as well as improving the reliability of the device. The goal is achieved by making the contact assembly in the form of a fixed contact consisting of two conductive half-rings and two springs w, their contacts placed on a movable stop interacting with the feed material. As a result, control is provided for a given length of the material to be supplied and to issue a command to disconnect the automaton coupling when the size of the feed material deviates to both sides from the specified one.

Description

The invention relates to mechanical engineering, in particular to the design of control systems for the operation of equipment for pressure treatment.

The purpose of the invention is to expand the technological capabilities by ensuring control of the tolerance for the length of the feed material in both directions from a given value, as well as improving the reliability of the device.

The drawing shows the block diagram of the device.

The device contains an spring-loaded stop 1, exchanged with the possibility of reciprocating movement in the housing 2, which is mounted on the base 3 with the ability to move with the help of vipt 4. iia spring-loaded unor 1 is equipped with a movable contact 5, and .lka 6 with a fixed contact element7, which in the form of two isolated from each other wire of half-rings, of which is connected to tokoprozo; 8 ohm through a resistor n 1Y divider 9 with a two-input counting) pre-selection), which It is possible to: 1-akzha, to the power source 11 and the command device 12. Sensors 3 and 14 of the command unit 12 and the node 15 of the automatic machine clutch are connected to the relay 10. Komandoanparat 12 and the node 15 of the aBT ivaTa clutch in general In this case, a Ba; iy 16 automat is installed on the machine; A spring 18 is placed between the shoulder of the stop 1 and the body 2.

The device works as follows.

In the case of non-revenue, the non-moving contact 5 at the end of the feed to the fixed contact element 7 (i.e., the material is supplied with a menn of a predetermined value) or the location of the movable contact 5 behind the element 7 (as a result of supplying the material more than a specified value) the signal does not pass, while from the sensor 13 a triangular electrical signal is received. As a result, the electrical joint, which appears on the counting input of the relay I), is remembered in the middle. In these cases, the control unit electric signal from the sensor 14 and the input of the relay 10, triggers it depending on the program that has been programmed (de-interrupting the operation and 1 through the set number of continuous numbered commands). Relay 10 delivers an electrical switch to node 15 to turn on hardware. on.

When the material is fed to a given pickup and R within the deadline determined by the width of a fixed KOiiTaKTfioro element 7, at the end of the feed the contact between the signal and the contact contact is always formed, which ensures an electrical signal .; ia on de. 1and 1 spruce 9 and to the zero input of the electronic ope pe..je if).
