Definitions
- the present invention relates to a vertical stacking system with at least two valve assemblies on a row plate, to a vertical adapter for use in such a vertical stacking system, to a module for use with at least two hydraulically connected valve assemblies and to a method for the electrical and mechanical connection of two non-conductive components.
- valve assemblies 102 are located on a row plate 100, which replaces several individual connection plates of non-linked valves. 5 and 6, only one pressure port 101P and one tank port 101T are provided for all valve assemblies. Connections 103a to 103f to the consumers are located on the side faces of the row plate.
- the valve assemblies 102 have e.g. Pressure, flow or shut-off valves as intermediate plate valves and each have a directional control valve as the final element. The valves are thus combined to form control circuits through which the individual consumers can be controlled.
- Such a vertical stacking system allows assembly operations to be combined and complete control circuits to be easily replaced or modified. Furthermore, the space requirement decreases and the effort for the hydraulic connection of the individual assemblies is reduced. In addition, when properly assembled, functional reliability is increased and troubleshooting is easier compared to arranging in a separate pipeline network.
- the disadvantage of this prior art vertical stacking system is the complicated electrical wiring. Each valve is connected to a control device by one or more cables that usually exit laterally. Although the cables can be combined in the form of cable harnesses or ribbon cables, a large volume is taken up by the cable's different exit locations from the valves. Wiring errors can also occur in wiring harnesses and ribbon cables, which can damage the valves.
- valves are controlled by a programmable logic controller.
- Subordinate group controls are supplied with command signals by a master control.
- the group controls in turn control the individual valves. If valve assemblies arranged next to one another are to be controlled by group controls provided at different locations, this results in a confusing wiring of the valves, even with the use of cable harnesses or ribbon cables, which can lead to increased errors.
- European patent EP 0 596 214 A partial solution to this problem is disclosed in European patent EP 0 596 214.
- This patent specification relates to a solenoid-operated hydraulic valve, which is shown in FIG. 7 and in which electromagnets 201, 202 are arranged on two sides of a base body.
- a connecting plug 204 is located between the electromagnets 201, 202 and on the base body 203.
- the connecting plug 204 has plug contacts 204a, 204b, 204c, 204d on the surfaces facing the electromagnets 201, 202, into the contact pins 201a, 201b attached to the electromagnet 201 or contact pins 202a, 202b attached to the electromagnet 202 can be inserted. Also introduces Cable away from connector 204 through which the hydraulic valve is powered.
- the solenoid-operated hydraulic valve according to patent EP 0 596 214 is assembled by first placing the electromagnets 201, 202 in a position remote from the base body 203, then attaching the connector plug 204 to the base body 203 and finally the electromagnets 201, 202 to the base body 203 are moved, whereby the contact pins 201a, 201b, 202a, 202b come into engagement with the plug contacts 204a, 204b, 204c, 204d. An electrical connection between the hydraulic valve and the connecting piece is thus established. There is only one cable with, for example, four electrical lines for the electromagnets to the hydraulic valve.
- Such a solenoid-operated hydraulic valve has the disadvantage that a cable with a connector is necessary for valve assemblies for each solenoid-operated valve.
- a large number of control circuits on a row plate in a vertical stacking system according to FIG. 5 a large number of cables is therefore necessary, which is not conducive to clarity.
- the length of the cables to external control devices, e.g. Programmable logic controllers cause losses. Consequently, with this solenoid-operated hydraulic valve, the increased space required by cables to the side of the valve assemblies is avoided, but the problem of a clear supply of electrical energy in a large number of centrally controlled valve assemblies is not solved satisfactorily.
- a vertical stacking system with at least two valve assemblies in which the power supply of electromagnets to the valve assemblies is carried out effectively, the clarity of the electrical connections to the hydraulic valves is increased and the space requirement is reduced, a height adapter for use in such a height stacking system, a module for use with at least two hydraulically connected valve assemblies, by means of which the electrical connection of the valve assemblies is simplified, and a simple and quickly implementable method for electrical and mechanical connection of two non-conductive components.
- the at least two valve assemblies are thus arranged between a row plate and a connecting plate, the hydraulic connection of the valve assemblies taking place via the row plate and the electrical connection via the connecting plate.
- the wiring effort is reduced and the entire vertical stacking system can be regarded as a hydraulic and electrical module that can be replaced with little effort.
- the connecting plate runs parallel to the row plate.
- the valve assemblies including the height adapters have the same height, which means that a compact system that can be arranged in different orientations in the room can be implemented.
- a connection base can be provided on the connecting plate, via which hydraulic components on the valve assemblies, such as a pressure switch, can be electrically connected to the control circuit. As a result, the area of application for the vertical stacking system according to the invention is expanded.
- connection block If a switching amplifier provided on the vertical stacking system is connected to the connection block, only low-voltage control signals need be supplied to the vertical stacking system, which are then processed in the switching amplifier. This makes it possible to integrate the vertical stacking system into a bus system.
- a connection device on the vertical stacking system can establish the electrical connection.
- the vertical stacking system is additionally coupled to a control device, which can have a programmable logic controller.
- the height chaining system can be controlled via an external control system, e.g. a personal computer, a central controller and / or a programmable controller. This makes complicated hydraulic processes easier to manage.
- an external control system e.g. a personal computer, a central controller and / or a programmable controller. This makes complicated hydraulic processes easier to manage.
- valve connecting sections support the modular structure of the vertical stacking system, since different valve assemblies can be provided with the same connection surfaces.
- the mechanical connection between the connecting sections, height adapters and the connecting plate is preferably made via snap or snap connections, which enables simple assembly and disassembly of the vertical stacking system.
- the electrical connection in the vertical stacking system is preferably carried out via electrically conductive channels which are connected in the assembled state and which can be provided in the connecting section, in the vertical adapter and in the connecting plate. This eliminates the need for external wiring.
- Plug elements between the electrically conductive channels facilitate the assembly of the vertical stacking system and ensure a reliable electrical connection.
- the connecting plate, the height adapter and the connecting section are made of insulating material, preferably of plastic.
- a height adapter for such a linkage system fills the spaces between the valve assemblies and the connecting plate and enables a mechanically stable construction of the linkage system.
- Height adapters with different heights can be used, which makes it possible to adapt various types of valve assemblies.
- a module for use with at least two hydraulically connected valve assemblies can be provided as a component for the electrical connection of a plurality of valve assemblies, an adaptation to the specific valve assemblies taking place via height adapters. Analogously to the use of just one row plate, which establishes the hydraulic connection, a single module can thus be used for the electrical connection of valve assemblies.
- a plug element is partially inserted into a channel of the first component and, after placing a channel in the second component on the plug element, a snap connection is made between the two components, whereby the plug element for mechanical and electrical Connection is used, while the locking connection is only for mechanical connection. In this way, a connection with a minimum number of components can be reliably established.
- connection method can be used both for connecting the connection section to the height adapter and for connecting the height adapter to the connection plate, and for connecting the connection section to the connection plate. As a result, these components can be quickly connected to each other. Height stacking systems in various configurations can therefore be produced in a short time.

- valve assemblies 2a, 2b, 2c, 2d, 2e are located next to one another on the upper side of the row plate 1 in FIG. 1 and are hydraulically controlled via the row plate 1.

- the valve assemblies 2a, 2b, 2c, 2d, 2e each have a different number of functional units and / or different nominal values.
- the overall height of the valve assemblies 2a, 2b, 2c, 2d, 2e arranged on the row plate 1 differs. This different overall height has proven to be a hindrance in the state of the art with regard to an efficient and clear power supply for the valve assemblies.
