Definitions
- the invention relates to a valve station for use in connection with the control of fluid-actuated devices, for example working cylinders, with a fluid distributor having internal fluid channels, which is equipped with electrically actuated pneumatic valves that communicate with the fluid channels, and with a signal distributor, from which the Pneumatic valves receive their electrical actuation signals.
- Valve stations of this type which are also referred to as valve terminals, are derived, for example, from German utility model G 92 11 109. They have a plate-like fluid distributor, inside which there are fluid channels that communicate with the pneumatic valves arranged on it.
- a signal distributor for example designed as a control unit, is in electrical connection with the valve actuators of the pneumatic valves and supplies the necessary electrical actuation signals. In this way, the valves can be switched as required in order to control connected fluid-operated devices with regard to their mode of operation.
- Such a valve station allows the actuation of fluid-operated devices from a central location. This facilitates both the set-up and later operation, including monitoring of machines and systems that are equipped with fluid-operated devices. If these fluid-actuated devices are not only pneumatically actuated but also hydraulically actuated devices, so far, however, a completely separate control has been carried out, since in hydraulic operation different parameters come into play than in pneumatics. The constructional effort is therefore enormous, especially with regard to the electrical and electronics that are required to control the different types of valves.
- the object of the present invention is to reduce the structural outlay incurred in connection with the parallel operation of pneumatic and hydraulic valves.
- valve station is designed for combined control of both pneumatic valves and hydraulic valves, and has at least one control connection for connection to at least one electrically actuable valve drive of a hydraulic valve.
- both pneumatic valves and hydraulic valves can be controlled and actuated via a single valve station, which allows an optimal function linkage. It is possible to control both types of valve via a common control unit, which is particularly advantageous if the control unit is formed by the signal distributor of the valve station and forms a direct part of it. It has been recognized that pneumatics and hydraulics can be linked in this way without mutual interference, which in particular considerably simplifies the installation work and the operation of complex systems or machines.
- control connections would be conceivable, in particular, connecting devices which are installed in or on the fluid distributor and with which the valve drives of the hydraulic valves can be automatically coupled when the assigned fluid distributor is equipped.
- control connections for the hydraulic valves as connections for at least one signal conductor, via which external hydraulic valves can be connected, that is to say hydraulic valves which do not form a direct part of the valve station.
- valve station In the case of the control of external hydraulic valves, it is expedient to provide the assigned control connections in at least one control part of the valve station, which can be integrated in the signal distributor, but is expediently a separate component or module which forms a fixed, possibly detachable part of the valve station . If several such control parts are provided, the valve station can be constructed as required; one could speak of a modular valve station.
- valve station can also have further outputs and / or inputs for control signals, which in particular are also provided on at least one control part.
- Signal conductors can be connected to them, in particular to Monitoring devices such as sensors or the like. to lead.
- the valve station 1 shown in FIG. 1 contains a fluid distributor 2 for pneumatic pressure medium.
- a plurality of pneumatic valves 4, which are multi-way valves, are detachably arranged on an assembly surface 3 of the fluid distributor 2.
- the valve channels of the pneumatic valves 4, which are not shown in detail, communicate with internal fluid channels 5, that is to say inside the fluid distributor 2, which are only partially indicated by dashed lines.
- One of these fluid channels 5 is expedient a feed channel 6, which can be connected to a pressure medium source P via a connection opening 13 and which, on the other hand, opens out in the region of each valve 4 to the mounting surface 3.
- a fluid channel 5 serving as an exhaust air duct 7 has a corresponding course, to the central outlet opening 14 of which a muffler or an exhaust air duct which holds the exhaust air can be connected.
- Each pneumatic valve 4 communicates both with the feed channel 6 and with the exhaust air channel 7 via the openings on the assembly surface 3. Furthermore, each pneumatic valve 4 communicates with at least one and in particular two consumer channels 8 of the fluid distributor 2, which open on the outside of the fluid distributor 2, so that pressure medium lines 12 can be connected, which lead to pneumatically actuated devices 15. In the exemplary embodiment, for the sake of simplicity, only such a device 15, which is a working cylinder, is shown schematically.
- connected pneumatically actuated devices can be supplied with compressed air or vented.
- the pneumatic valves 4 are actuated electrically. They each contain an electrically actuable valve drive 16, which regularly contains at least one electromagnet, and which is preferably a so-called solenoid valve. Each valve drive 16 is in electrical connection with an electrical conductor arrangement 17, which extends along the fluid distributor 2, in particular within the fluid distributor 2 in a suitable channel. For the connection to the valve drives 16, electrical plug-in means are expediently provided, so that the electrical connection is established automatically during valve assembly.
- the electrical conductor arrangement 17 is based on a signal distributor 18 which is arranged on an end face of the fluid distributor 2 and in particular is permanently attached.
- the signal distributor 18 is formed by a control unit 22 which contains a control program and in particular is freely programmable, so that autonomous operation is possible.
- An interface 23 enables the connection of a computer (PC) for programming and setup purposes.
- Further interfaces 24 form outputs and / or inputs of a field bus, via the further signal distributors of other valve stations can be connected.
- a signal distributor 18 a fieldbus communication unit without its own control program, which communicates with an external control unit and receives the corresponding signals from it, on the basis of which the actuation signals are distributed to the pneumatic valves 4.
- a fieldbus solution conventional 1: 1 wiring would also be possible, in particular using so-called multipole lines.
- the signal distributor could be a simple bus that drives the valve drives.
- control part 25, 26 which communicate with the control unit 22 of the valve station via electrical conductors, not shown, by connecting them to the signal distributor 18, for example.
- the corresponding electrical conductors are not shown in the drawing, since they run inside the control parts 25, 26.
- Each control part 25, 26 expediently contains a conductor section which is continuous in the mounting direction, the conductor sections complementing one another in the assembled state to form a continuous conductor strand.
- control connections are on one of the control parts 25 27 provided, which are accessible from the outside. They are designed so that they can be used to control hydraulic valves 28 to which electrically actuable valve drives 32 are assigned.
- Each control connection 27 represents a control signal output which is in electrical connection with the individual valve drives 32 via one or more signal conductors 33.
- the signal conductors 33 can be wires or cables that can be laid easily and flexibly, so that the hydraulic valves 28 with their valve drives 32 can be installed practically any distance from the valve terminal 1.
- the valve drives 32 receive the control signals required for actuation, which are caused by the control unit 22, via the signal conductors 33 and the control connections 27.
- each control connection 27 an electrical and / or electronic output stage which is adapted to the valve drive to be controlled and which processes the electrical actuation signals coming from the control unit 22 in such a way that they act as direct actuation signals for the valve drives 32 of the hydraulic valves 28 can be used.
- control connections of the control part 25 are preferably designed as electrical plug connections, so that the signal conductors 33 can be connected or disconnected quickly.
- the valve station 1 of the exemplary embodiment is designed to control or actuate four hydraulic valves 28, which is why the relevant control part 25 has four control signal outputs or control connections 27. It goes without saying that a different number of control connections 27 can also be provided, for example only one.
- Each hydraulic valve 28 communicates with a system of hydraulic lines, indicated by arrows 34, which establish the connection to a supply source and a tank.
- a common line system 34 can be provided for all hydraulic valves 28.
- the hydraulic valves 28 are connected via consumer lines, which are indicated by further arrows 35, connected to the hydraulically operated devices, only such a device 36 is shown in simplified form, which is a hydraulic working cylinder. It can be seen that the hydraulic valves 28 can be attached directly to the device 36 to be actuated.
- the control part 25 forms a module of the valve station 1.
- the valve station 1 can be constructed in a modular manner to the desired extent.
- further control parts 25 can therefore be provided, which have control signal outputs for control connections 27 forming hydraulic valves.
- at least one further control part 26 which is provided with outputs and / or inputs 37, via which signals can be transmitted to and / or from other devices which are required for the operation of the valve station or from the latter be operated.
- outputs and / or inputs 37 enable the connection of monitoring devices such as sensors or the like, on the basis of whose signals the control unit 22 carries out the distribution of the electrical actuation signals.
- a control part 25 is provided exclusively for the control of hydraulic valves 28, while a control part 26 is provided exclusively with outputs and / or inputs 37 for monitoring devices.
- a single control part can contain a mixture of inputs and outputs or control connections of various types.
- valve station 1 which is suitable for the combined actuation of both pneumatic valves 4 and hydraulic valves 28.
- a common control unit 22 is sufficient to control both types of valve, which results in a relatively low construction effort, particularly with regard to the electronics side. It is possible to precisely coordinate the actuation of the pneumatic valves and the hydraulic valves, an actuation which is independent of one another being feasible. Due to the modular structure of the valve station, it is also possible to operate it with only one of the two valve types if necessary. One could omit the control block 25 and would have a valve station equipped and working exclusively with pneumatic valves. It would also be possible to omit the fluid distributor 2 with all pneumatic valves 4 and the remaining part of the valve station exclusively for actuation and actuation of hydraulic valves 28 to use.
- the fluid distributor 2 as such also be of modular construction, which is the case in the exemplary embodiment.
- the fluid distributor 2 is subdivided into a plurality of length sections which form adjoining distributor modules 38, each of which is equipped with at least one pneumatic valve 4.
- the pneumatic part can thus be expanded practically as desired.
- valve assembly 2 schematically shows the possibility of arranging both pneumatic valves 4 and hydraulic valves 28 directly on a fluid distributor 2 'of the valve station 1.
- the electrical conductor arrangement 17 emanating from the signal distributor 18 serves for the simultaneous supply of both valve types with the necessary electrical actuation signals.
- the control connections 27 are provided here in the area of the assembly locations for the hydraulic valves 28 and are connected to the electrical conductor arrangement 17, the electrical valve drives 32 of the hydraulic valves 28 advantageously being automatically connected to the control connections during valve assembly 27 can be connected.
- one can also provide a separate electrical conductor arrangement for the hydraulic valves 28 (not shown), which, however, expediently extends parallel to that for the pneumatic valves 4.
- the fluid distributor 2 'contains two mutually independent channel systems for the two valve types, which is indicated in FIG. 2 by arrows P p / R p and P h / R h . Both channel systems can run according to the internal channel profile in the fluid distributor 2 of the embodiment according to FIG. 1. However, it is advantageous here if the fluid distributor 2 has its own distributor module 39, 39 'for each valve type, each of which has its own channel system. In the exemplary embodiment, two such distribution modules 39, 39 'are provided, one (39) of which is equipped with a pneumatic and the other (39') with a hydraulic channel system. A fluidic connection between distributor modules 39, 39 'of different types is not necessary in this case, but the electrical series connection is expediently retained. The distributor modules 39, 39 'can be subdivided even more modularly.
- valve station 1 can also have control parts 25, 26 (not shown in more detail), via which a signal connection to external devices takes place. You can combine the possibilities of setting up a valve station shown using the two exemplary embodiments.
- both the control parts 25, 26 and the distribution modules 38; 39, 39 'in a linear mounting direction 40 can be successively attached to one another, the control parts 25, 26 on the one hand and the distributor modules 38; 39, 39 'are expediently attached to opposite sides of the signal distributor 18, which itself expediently has a block-like structure.
