This invention relates to equipment for moistening shoe blanks.

The aim of the invention is to increase the productivity of the wetting process.

Fig. 1 shows the functional scheme of the device when chamber I is not disconnected from vacuum pump I for the period of moistening; in fig. 2 structural diagram of the regulation of the temperature of the steam generator

The device contains a Kah-Seru 1 for moistening (Fig. 1) with a lid 2 dp sealing it, with a drive 3 flaps 2 and a holder 4 of the blanks 5,

The device includes a vacuum system 6 connected to chamber 1 by means of valve 7 and a pair of generator 8 with heaters installed in it (at least two in FIG. 2) immersed in water to which the temperature controller 9 is connected, supporting temperature of water.

The steam generator 8 is connected to the chamber 1 by means of a steam supply valve 10, which in turn is connected to the chamber by a pressure sensor 11 in the chamber for supplying steam, wherein: COMMUNICATION is performed as follows; The sensor input 1t is connected to: chamber 1, and the output to the steam supply valve I 10. As a valve I 10 can be used electro-I solenoid valve

I control relay 12; for automatic opening; 1 of the temperature controller 9 from the steam generator 8, the input is connected to the steam supply valve 10; As a relay 12, any known relay can be used, for example, electromagnetic turnips with or without time relays.

In order to broaden the technological possibilities of controlling steam generation in control relay 12, as mentioned above, it can be entered: but a time relay, the function of which EIXO returns the unit to its original state before the steam stops after the set time has passed

FIG. 2 shows a steam generator B, a temperature controller 9, a steam falling valve 10, a relay 12, a steam generator heating control unit 13,

the node 14 of the electric heaters, the temperature sensor 15, the measuring device 16 and the relay block 17.

Symbol of communications (fig 2) and their functional purpose; 18 turning on the steam generator at maximum power; 19 - permission to control the temperature of the steam generator; 20 - control of the relay unit; 21 - regulation of the temperature of the steam generator; 22 - the inclusion of a group of heaters; 23- inclusion of all heating elements; 24 - disturbing effect of temperature on the sensor; 25 - temperature signal of the steam generator; 26 - turn on the relay 12.

To explain the control of the temperature of the steam generator, consider the circuit shown in FIG. 2,

Prior to the supply of steam from the steam generator 8 to the chamber 1, the valve 10 is closed, the relay

12 is disconnected and the link 18 is zero, and the link 19 is a single signal. As a result, the relay 12 is the link.

18 generates a zero signal to the steam generator, and via communication 19 produces a single signal allowing the measuring device 16 through the relay block 17 to regulate the temperature in the steam generator.

When a signal is received from the steam supply valve 10 (Fig. 1), a relay 12 is triggered. As a result, two signals appear at the output of the latter: the first issues a command to prohibit temperature control to the temperature controller 9, the second switches on the heaters of the steam generator 8 to full power.

From the sensor 15 (FIG. 2), a temperature signal is transmitted to the measuring device 16. As a result of this, from output 9 of block 16 via communication 20, a corresponding level of control signal (1 or O) is supplied to relay block 17. When the signals match

19 and 20, the block 17 of the relay is activated and, through communication 21, turns on the node 13. The node

13, in connection 22, includes steam generator heaters. If the signals 19 and 20 do not match, the steam generator heaters are turned off. Thus, the temperature is regulated.

At the moment of steam supply to the steam generator 8, the valve 10 is open and, at the output of the relay 12, the communication 18 receives a single value and the communication 19 - a zero value. The zero link value 19 provides

regulator 9 from the steam generator to shut off the rator.

When the valve 10 is turned off, the relay 12 is triggered, which ensures that the temperature regulation is stopped by the regulator 9 in the steam generator 8 (i.e. the regulator 9 is disconnected from the node 13).

When the steam supply stops, the relay 12 boevr returns to its initial position and the water temperature is maintained automatically.

A device for moistening the blanks of the upper of the shoe works as follows.

After manually loading the holder 4 with the products 5 (FIG. 1), the operator issues a command to operate the device.

Hermetically sealed with a lid 2, the chamber 1 is connected to the vacuum system 6 by means of the valve 7. After the vacuum in the chamber reaches a certain value from the sensor 11, a signal is given to open the valve 10 connecting the chamber 1 to the generator 8.

When the steam supply valve 10 is opened, a signal is sent to the relay 12, which turns off the automatic controller 9 for maintaining the water temperature including all heaters of the steam generator B at the same time. The work pieces are moistened. After the specified humidification time has elapsed, the steam supply valve 10

closes. Relay 12 includes an automatic controller 9 to maintain the set temperature of the water in the steam generator 8.

At the end of the cycle of operation of the chamber, the latter, by valve 7, is disconnected from the vacuum system 6, connected to the atmospheric system, and the actuator 3 removes the nut from the chamber. Wet blanks 5 removed from the holders 4.
