Description

The known galvanic cover automata require the coordination of the operation of two independent mechanisms: the product transfer mechanism and the product lowering mechanism, which provides preparatory and final operations for the movement mechanism to operate.

In the proposed automaton, due to the presence of blocked individual drives, the mechanisms are operated without interrupting one of the drives during operation, and each drive is switched on and off once per cycle. Such an implementation facilitates the changeover of the automaton and makes it possible to improve the coordination of working out the mechanisms.

The drawing shows the kinematic diagram of the automaton.

A horizontally closed chain conveyor / with cross-arms 2, at the ends of which suspensions with parts m and 3 are attached, periodically moves one way over the cross-arms. This movement is carried out by switching on the electric motor 4 and is fixed by pressing the next stop 5 on the limit switch 2KB.

From the engine 6, through the drive 7, the movement is transmitted to the camshaft (9 with cams 9. Through these cams, through the lever mechanisms 10, the suspensions with parts 3 are raised and lowered. Cams 11 are also installed on the camshaft, which act on the limit switches 1K.V. ZKV and 4K.V.

The cycle of operation of the automaton consists of holding the products in the bath and the period of testing, when the mechanisms of the automaton lift the products out of the bath and transfer them to the next bath and again lower into the bath for holding. The duration of a single exposure is regulated by the relay.

of time.

The switch-on of the machine is made from the button of the drive of the camshaft 8 or from the time relay. Camshaft turning at an angle.

corresponding to the lifting of suspensions, switches on by means of a switch // (the chain conveyor /, which will work until the next stop 5 presses 2 / CB, located on the chain movement path. By placing 2KB along the conveyor route, the suspensions from the product are directly oriented mi baths regardless of the operating conditions of the drive.

From the moment the chain conveyor drive is switched on, both drives work simultaneously. Before starting to lower the nodes, one of the cams // will press on the SCR and switch the motor control circuit 6 through the normally open contacts of the switch 5 / C5. If the chain conveyor does not work by the moment of pressing the SCW, the camshaft drive will stop until the conveyor is completed.

After lowering the lodwigs in the baths, the third cam disk // will press the 4K.V switch, which will turn off the cam shaft drive and turn on the time relay.
