Definitions
- the present invention relates to an air jet loom with a device for compressed air supply.
- An air jet loom with a device for compressed air supply shows, for example, EP 1 288 359 A1.
- Several pressure regulators or pressure reducing valves are connected to the internal compressed air distribution line.
- the pressure regulators are pneumatically or motor controlled or adjustable.
- EP 1 288 359 A1 proposes to activate each group of air nozzles of a motor-controlled pressure regulating valve assigned to this group in conjunction with a pneumatically controlled pressure regulating valve.
- Such an arrangement is expensive and complex in construction.
- the object of the present invention is to use only a single electrically controlled pressure adjusting means for electronically setting different air pressures for different groups of air nozzles or other air consumers on an air jet loom.
- the air jet loom has several pneumatically adjustable pressure regulators.
- Such pressure regulators usually have inputs for the supply air and for a pneumatic control pressure and a pneumatic output.
- the different air pressures - for example for the supply of air nozzles or of different groups or types of air nozzles - are adjustable in that Various control pressures are applied to the pneumatic control input of the pneumatically adjustable pressure regulator.
- Pressure reducing valves known. When a particular pneumatic control pressure is applied to the control input, these devices reduce and regulate the air pressure from the central compressed air supply line or from the internal compressed air distribution line of the weaving machines to a constant value at the pneumatic outlet of the pressure regulator.
- the air jet loom also has an electrically controllable
- Pressure adjusting means with a pneumatic outlet.
- Such electrically controllable pressure adjustment means are known to the person skilled in the art, for example as a motor-controlled pressure reducing valve from EP 1 288 359 A1.
- the motor moves an actuator in the pressure reducing valve or pressure regulator and via this actuator, the air pressure from a central compressed air supply line or from the internal Druck Kunststoffverteiltechnisch the weaving machines to a constant value on
- pneumatic output of the electrically controlled pressure regulator is reduced and regulated.
- the electrical control is usually via the weaving machine control.
- a control pressure line is present in which different air pressures or control pressures can be generated by the electrically controllable pressure adjustment means.
- a plurality of electrically switchable valves are present, which are each assigned to a pneumatic control input of the pneumatic pressure regulator.
- an associated pneumatic control input to the control pressure line can be connected via these electrically switchable valves.
- one valve after the other is opened during operation of the air-jet loom, so that only one of the pneumatic control inputs with the
- Control pressure line is connected.
- valves can be controlled by the loom control at the times required for the desired pressure curve in the control pressure line and the connected pressure regulators.
- each of these groups can have its own pneumatically adjustable
- Pressure regulator can be assigned. By electronically setting various control pressures in the control pressure line and by opening the various, each one pneumatically adjustable pressure regulator upstream valves can be on the pneumatically adjustable pressure regulators each set different air pressures - for example, for different groups of air nozzles. For this purpose, however, only a single electrically controllable Druckeinstellstoff - ie, for example, an electrically adjustable pressure regulator - and for each group of air nozzles requires an additional electrically switchable valve.
- the appropriate valves - e.g. Solenoid valves - are much simpler in design, easier to control and significantly cheaper than electrically adjustable pressure regulator.
- an electronic weaving machine control with an input device for the various air pressures to supply the air nozzles will generally be provided.
- the weaving machine control has electronic means with which the pneumatic control inputs of the pneumatically adjustable pressure regulator via the electrically switchable valves at predetermined times with the control pressure line can be connected.
- FIG. 1 Schematic representation of an embodiment of
- Figure 1 shows an embodiment of the device for compressed air supply of the air jet loom according to the invention.
- the air jet loom has a compressed air distribution network 7, via which the components in the air jet loom are supplied with compressed air from an external supply network.
- each pneumatically adjustable pressure regulator 1 .1, 1 .2, 1 .3 has a pneumatic output 2.1, 2.2, 2.3 and a pneumatic control input 3.1, 3.2, 3.3. From the outputs 2.1, 2.2, 2.3 the compressed air is passed on to different air consumers. In the case of the pneumatically adjustable pressure regulator 1.1 and 1.2, these are two different groups of air nozzles, not shown, for the weft insertion on the air jet loom. Between the air nozzles and the outputs 2.1, 2.2 of the associated pneumatically adjustable pressure regulator 1 .1, 1.2 is still an air tank 8.1 or 8.2 and not shown valves.
- an unillustrated air consumption element is connected without additional air tank in the present case.
- the pneumatically adjustable pressure regulators 1 .1, 1 .2, 1.3 each have a pneumatic control input 3.1, 3.2, 3.3.
- the air pressures at the outputs 2.1, 2.2, 2.3 of the pneumatically adjustable pressure regulators 1 .1, 1.2, 1 .3 are regulated to different high air pressure values.
- Pressure regulator 1 .1, 1 .2, 1 .3 is a single electrically adjustable pressure control valve. 4 intended. This is executed in the exemplary embodiment in a known manner by a motor adjustable, the motor receives its control signals from a loom control, not shown. On the loom control also an input option (not shown) for the various at the outputs of the pneumatically adjustable pressure regulators 1 .1, 1, 2, 1.3 required air pressures.
- the loom control is designed such that in a predetermined time sequence in the control pressure line 5 - that is, at the output of the electrically adjustable pressure regulator 4 - a number of different air pressure values is generated. Each time one of these air pressure values at the output of the electrically adjustable pressure regulator 4 and thus in the control pressure line 5 is applied, an electrically switchable valve 6.1, 6.2, 6.3 is opened, the
- Control pressure line 5 to the pneumatic control input 3.1, 3.2, 3.3 of a pneumatically adjustable pressure regulator 1 .1, 1 .2, 1 .3 connects. About the now applied control pressure, the output pressure of the pneumatically adjustable pressure regulator 1 .1, 1 .2, 1.3 is set. Subsequently, the electrically switchable valve 6.1, 6.2, 6.3 is closed, the electrically adjustable pressure regulator 4 is set to a new, predetermined by the weaving machine control value and the next electrically switchable valve 6.1, 6.2, 6.3 is opened. Thus, the next pneumatically adjustable pressure regulator 1 .1, 1 .2, 1 .3 is set to a predetermined air pressure value at its output 2.1, 2.2, 2.3. Other time sequences of the switching operations, such as simultaneous switching of several electrically switchable valves is on demand via appropriate programming of
