SU74249A1 - Cyclic multi-command time relay - Google Patents

Description

The subject of the invention is a cyclic multi-command time relay, in which the drum, connected via a shift gear to a driving motor, is provided with transient cams, acting on the contacts of controlled electric circuits.

A feature of the invention is the application of an intelligent disk controlling the connection of the drum (for example, by means of a coupling or similar mechanism) to the drive axis so that the last for one Connection performs a certain number of commands.

Command blocking (preventing a new command from the unfinished performance of the old one) is performed using an additional cam on the drum, disconnecting the drive motor circuit if necessary. In Figures 1 and 2, a diagram of the proposed relay is shown.

From the electric motor M (Fig. 1), connected by a flexible coupling to the shaft / via a gearbox /, shaft II, gears 2, 3, 4, and 5, shaft IV, interchangeable tuning wheels during c-Ikl v, d, e (or velocity box) on sleeve VII, movement is transmitted to the cycle time disk 22.

The disk 22 has grooves 13, in which the cams 12 move and fix. When the disk 22 rotates, the cams 12 turn off via pin 14, Solenoid 20, lever 19, trommel sleeve 18, levers 15 with ring 16, drum 11 and friction clutch 8, force c :), which is regulated by a ring 17 screwed onto the sleeve V. The friction clutch 8 is turned on after the second cam 12 is disconnected on the disk 22 of the contactor 14 with the solenoid 20 by means of a spring 21.

The inclusion of the friction clutch 8 movement from the engine -.VI, through the shaft /, gear 1, shaft //, interchangeable tuning wheels for speed a and b (or gearbox), shaft ///, gears 6 and 7 11 commands transmitted to the drum.

When the friction clutch 8 is turned off, the drum // is shifted to the right by the action of the spring 10 and is braked by a cone 9.

In the pits 13 of the drum 11, the cams 12, which interact with the contactors 14, are strengthened. Each contactor 14 controls one body of the working machine when an additional relay Kp is activated, powered by the transformer T.

Contactor 14 (Fig. 2) is designed for instant on and off. A ba, a raban 11, or a disk 22 with a cam 12 presses a shoe 33 fixed on the lever 23 and turns the lever relative to the axle 5 to the right. With this, the doggie 29 rolls over for the required number of teeth of the ratchet wheel 27, the rotating shaft 33 of the axis 33, stretching it alone; 1 spring .2-. When the cam 12 passes behind the shoe 33, the spring under the action of the spring 24 from the cam 12 and the lever 23 instantly Venio is turned to the left, the winding wheel 27 and the hinge wheel 27 and the 36-day pin connected with it are connected. juicy cam 28.

The cam 28 will turn the lever 30, which, when lowered, will close the lower two contacts, and when it moves through the rod, 31 is the upper two contactors of the contactor 14. After turning under the action of the irons 32, the lever 30 sinks into the groove of the cam 28. This position is fixed by BaiexcH rubber L1 25 with adjustable SCREW: 26, stopping pin 23.

With two rows of cams ii of levers, it is possible to give mutually opposites to the other teams through very short intervals. So, the ir of two rows of rasolozhuiny cam 12, one of which is slightly shifted in the direction of rotation, both levers 23, simultaneously retreating to the right, will drive dogs, ki 29 by the tooth of the storage wheel 27. When one lever 23 is disrupted from the cam 12 One is performed by a team, and if it is broken from the second ivy, the opposite of the comagda control of the relay can be automatic and semi-automatic. When the car is running, its start-up cycle is automatic. izvodits with the VK switch. When crawling: a tomato cycle. (The VC button is closed), at its okoychaya, the cam 12 through the co-factor 14 breaks the circuit of the engine M of the engine and the relay stops. To start the next cycle, press the start / start cuff (the stop and the start are indicated in the drawing) until the other K vTa40K 12 is locked through the coaxial circuit of the motor current.

In the case of a new command, before the execution of the old, but-va command is blocked, 1 and the assistance of the additional cam 12 and the contactor 14. The latter breaks the engine circuit, which is given to the new command. If the previous command is complete, then the worker op, ghana MAiJIlHy will close the switch K, In the line, TOiKa engine, and the relay will continue to work. If the previous command is not closed, the button K, B is not turned on and the engine stops until that moment when the stop of the machine's working element closes or opens the NOK.1 with the short-circuit lever of the engine current line.
