ILJONBERG worked in the carpet industry. We made an automatic loom, from which
the electrical circuit diagram is available.

Principle

The carpet shuttle (1.5 m) traveled a distance of about four meters from one limit switch to another. The motor stopped, by means of a magnetic switch, when the shuttle reached the end point. The shuttle, on the other hand, was so light that it could be propelled by the motor as soon as it started.

Two contactors, three relays, a couple of diodes and limit switches were needed for electrification.

The diagram can be applied to other solutions – either to a single or to a pair of machines.

The instructions explain how to get a back and forth motion for the carpet shuttle.

 

How then is another machine connected to it?

The machine should have the possibility of a single stroke. It can also be done with a magnetic switch or inducing light movement when the machine is started.

If you have a single input, do for example the following:

* CROUZET microswitch with a lever 5 A 250 V Type 509.

* put a 'sweep pin' or 'sweep strip' in the conveyor near the end of the track. Connect the connectors of the microswitch so that the power enters the single connector and when the lever moves, the power goes through the machine's start button. The lever will return by itself when the conveyor or shuttle reaches the end point. In the other direction, the lever of the microswitch should only yield a bit.

At the other end, you do the same, but from a different input connector, route power the other machine's starter.

Power to the microswitch comes through the path formed by the intermediate relays.

Components (more detailed explanation included in the shipment)

re Limit switch's eccentric washer transmits the input to the impulse relay.

rl A limit switch guarding the top carrier's movement. The current flows through when the top carrier is in a resting position.

rv and ro are the limit switches for the left and right side of the shuttle

K1, K2 contactor relays

diodes, impulse relay, intermediate relays

When you study the blueprints you receive, you will notice that the machines can be synchronized with each other to work in shifts.

If you want a long chain of several machines, the impulse relay on the last machine causes the current spike to start the sequence from the beginning.

Isn't it interesting to make the machines work with common sense.

Engineers could of course figure out the power consumption of the necessary conductors and relay coils, but we happened to get it right. Only DC relays 5A 24VDC were requested.

10,000 carpets were woven.
