Electromagnetic control station with software control of technological modes is applied.

FIG. 1 shows the camera shutter (cross section); in fig. 2 — a pneumatic device for inserting carriages into and out of the chamber (longitudinal section and top view); in fig. 3 is a longitudinal section of the chamber; in fig. 4 is a schematic diagram of the electrical control of the apparatus; in fig. O - technological scheme of the device.

The closure for sealing the chamber - (fig. 1) includes levers (located on the flange 2 of the upper part of the chamber), a locking ring 5, which is installed in the U-shaped groove of the lower flange 4 of the chamber.

The operation of the shutter is as follows.

As soon as the upper part of the chamber is lowered down, and the levers / upper flange 2 go into the grooves of the lower flange 4 and the locking ring 5, under the influence of a pulse of the limit switch that controls the lower position of the chamber, the pneumatic actuator will operate, which will turn the locking ring 5 until it stops and will thereby jam levers / top flange 5.

A pneumatic device for inserting into the chamber — and withdrawing from it carriages with stockings (FIG. 2) consists of two successively located pneumatic cylinders 5 with pistons G on a common rod 7 carrying one rail connected with gear 8 connected by a chain transmission (in Fig. 2 shows only the leading sprocket 9) and another rail with a carriage.

A hydraulic cylinder 10 is applied to adjust the speed of the carriage, the piston // of which is attached to the rod of 7 p-cylinder cylinders. The carriages with stocking forms are introduced into and out of the chamber by supplying compressed air into the working cavity of one of the pneumatic cylinders.

Chamber 12 (FIG. 3) includes two perforated partitions 13 located in the upper part of it. The rotary nozzles 14, enclosed in blocks and installed in several rows, are intended for spraying dye solution on the product. Perforated partitions 13 provide a uniform distribution of steam throughout the line of the carriage 15.

Software control of technological modes in the apparatus is carried out using a combined circuit (Fig. 4 and 5) using both electric and pneumatic equipment.

This ensures that the following process steps are performed:

automatic insertion of carriages into and out of the pressure chamber; automatic raising and lowering of the upper part of the chamber; automatic control of the operation of the motor pump circulating system; automatic control of the program with pneumatic drive valves installed on the supply lines for washing water, dye solution, compressed air, steam, exhaust solution ejection valves, pressure relief and circulation system valves; monitoring and maintaining the desired temperature of the dye solution in the circulation system; monitoring and maintaining a predetermined vapor pressure and compressed air in the chamber.

The operation of the process control circuits (Fig. 4 and 5) is carried out as follows.

When the electrical circuit is turned on with the 2UP- / package switch, the voltage is applied to the control and transformer transformers of the control circuits. The air lock ZAZ-I is included. The camera shutter is open. Switching the device into operation is possible only once, when there is a shock in the piping control of compressed air, since the coil circuit starts up the RP- / relay relay with the contact of an electric NiaHO meter KM-1. The device turns on the work of one 1h start buttons / SU - / - / (V-.

In this case, the carriage pressed one of the limit switches KV- / or K.V-2, controlling the extreme position of the carriages.

When the device is turned on, the magnetic starter U (-1 and motor D- / is turned on.) The chamber is lowered to the lower extreme position until the limit switch / (B-3 is opened. Motor D-1 is disconnected from the power network, and the pneumoelectric relay PED-O, which supplies air to the emergency valve AK and the motor of the software electropneumatic device, closes the contact KEP-A in the circuits of the pneumatic-electric relays PEP-2 and PED-3. The valves B-i B-3 and B-12 operate. the solution from the tank is fed through counter C -I and apparatus. The chamber communicates with the atmosphere.

The CEP-9 pneumatic caulk closes the B-.9 valve on the pipeline, which connects the chamber with the atmosphere. The CEP-B contact is closed in the intermediate relay RP-5 circuit, which prepares the RP-14 relay coil circuit for switching on. The CEP command set stops.

When the camera comes to the lowest position, the KB-3 limit switch will switch off the emergency hammer / 73- /. The camera shutter closes. The limit switch KB-6 will operate and turn on the electric motor of the circulation pump D-2.

When selecting a given portion of the dye solution, the contact of the SCh-1 counter closes, the relay RP-14 and the relay RP-6 turn on. The latter will turn off the pneumoelectric relays PER-2 and PER-3.

The dye supply pipeline is blocked with membrane valves B-2 and B-13. Relay RP-6 will also include CEP and pneumatic-electric relay PED-4. There is a steam supply to the chamber and the countdown of the dyeing time.

When the vapor pressure in the chamber reaches a predetermined pressure, the contact of the electric pressure gauge 2P max is closed, the RP-7 relay is turned on and the PED-4 pneumatic electric spool is turned off.

Steam supply pipe is blocked by valve B-4.

When the pressure in the chamber drops to the minimum specified value by the arrow, the manul valve closes the 2P contact, ",.,., Which causes the RP-8 relay to turn on, which disconnects the RP-7 relay and turns on the PED-4 pneumoelectric relay. The steam supply line opens. When the set temperature is reached, the contact of the electrocontact thermometer T max closes, which leads to turning on the RP-9 relay and turning off the PED-4 pneumoelectric relay.

Steam delivery is stopped. When the temperature drops to the minimum set point, the contact closes. H min, turns on relay RP-10 and turns off relay RP-9. The last, having been disconnected, will turn on the pneumoelectric relay PEP-4. When the dye solution reaches a predetermined temperature (but a decrease in pressure), a further increase in the predetermined pressure in the chamber occurs due to air supply through valve B-5. When the pressure in the chamber reaches above the permissible one, the contact P m: t.i closes. Thus, the RP-3 relay is turned on, which disconnects the PED-0 pneumoelectric relay. The emergency valve AK blocks the steam supply pipe.

At the end of the crash, the CEP-d contact is closed, the RP-11 relay turns on, valve B-9 opens, pressure is released, and valve B-10 opens, since the CAP-10 pneumatic deaerator is activated. Dye of the dye solution is drained, after which the vein is 3 –135867

No. 135867 4 tills at-5 and B-10 are closed. Further, the YaEP-2 contact includes the pneumoelectric relay PER-6 and the pneumoelectric relay PEP-3 - the water required for flushing is selected. The chamber is connected to the atmosphere with the valve В-3. Next, the CEP-b contact closes to prepare the circuit for the batch readout and stops.

At the end of the selection of portions of water meter SCh-2 closes the contact system. The RP-15 relay and the RP-13 relay are turned on, which lock itself and turn off the pneumatic electric relays PEP-6 and PED-3. Valves B-6, B-3 and B-12 are closed. The CEP is switched on again and the rinsing time counts down.

When the RP-13 relay is turned on, the NER-5 turns on - compressed air is supplied to the chamber. Then the CEP-2 contact opens - the supply of compressed air into the chamber is stopped.

After flushing, the CAP-9 and CEP-10 pneumatic caulifiers open valves B-.9 and B-10 - pressure is released and water is drained into the sewer, after which the magnetic starter K-3 is turned off and the electric motor of the circulating pump stops.

The CEP-11 pneumatic caulk opens valve B-11-supplying heated air. After the set drying time has expired, valves B-11 and B-10 are closed.

After the pressure in the chamber decreases to atmospheric pressure, the contact of the IP min. Gauge closes, the RP-4 relay turns on, preparing for switching on the PZ- / overheater circuit.

By the end of the cycle, the CEP-e contact turns on the RP-12 relay, switches off the command set of the CEP, and turns on the non-reciprocating PP- /. Air is supplied to the cylinder of the actuator IM-5. The shutter opens the camera. The KB-5 limit switch turns on the K-2 magnetic starter. The camera of the apparatus rises. In the upper extreme position of the camera, the KB-4 limit switch is activated. The camera lift motor stops. At the same time, the RP-2 relay is turned on, which, by disconnecting the RP- / relay, brings the circuit to the initial position.

The scheme provides a light signaling process for finishing products.

The combination of technological processes of stabilization and spinning in the chamber makes it possible to intensify the process of finishing hosiery products from synthetic and other fibers and to increase the productivity and labor.
