Line system for pneumatically or hydraulically working

Control and regulation systems

The invention relates to a line system consisting of open ones arranged on one side in a flat plate Channels that are covered by another plate, especially for pneumatically or hydraulically working Control and regulation systems.

The flat plates of such a line system, e.g. known from DAS 1 O93 625, consist of rubber or Plastic, into which the channels are pressed with the help of compression molds, which are known in the printing industry Process of making metal-rubber clichés are made.

For each application, this type of Manufacture new molds created and with these the channel plates are made. Such channel plates are therefore relatively expensive and only applicable to systems that are manufactured in large numbers.

Furthermore, when the line system is arranged in several levels one above the other, that represented by channels Wiring confusing and gives rise to errors Such channel plates are also not adaptable to other relationships or conditions. When changing switching conditions or control parameters so new molds have to be created and new channel plates produced with them will. This is very cumbersome and expensive.

So-called circuit blocks have therefore already been used with transverse and longitudinal channels that cross each other in four levels, which are interrupted by partitions. By removing the partitions from the longitudinal and transverse ducts Any line connections can be established. Apart from the fact that such switching blocks are difficult to manufacture due to the blind holes, the removal prepares the partition walls further difficulties and the course of the line is not visible. It can therefore be very Circuit errors easily occur, which only occur during commissioning of the system become recognizable. The construction of a line system with the help of such circuit blocks is also very great voluminous.

Finally, there is the construction of an extensive pipeline system Not possible or only with great difficulty in several levels one above the other.

The invention is based on the object of significantly simplifying the structure of a line system used for interconnecting, i.e. connecting, pneumatic or hydraulic logic and / or switching elements of a measuring, control or regulating device by means of a new channel plate, while meeting the requirements for greater safety in the _: Interconnection, great reliability in operation with small volumes and low production costs and, after slight adaptation to new tasks or new conditions, to be fulfilled to a greater extent than before *. / .. -.

Based on a line system consisting of in a 'flat plate open channels arranged on one side, which are covered by another plate, this object is achieved according to the invention in that instead of of the previous channels by separable bars from each other separate channel sections are provided, which according to

009842 / 073S

are arranged in a regularly recurring pattern in the flat plate.

Such an arrangement makes it possible for the first time to cut from one type of duct plate simply by separating Web pieces between the individual channel pieces any line connection within the scope of the given possibilities to create, in one switching level. The oiii .s t eing piping system can therefore be overlooked immediately. Since only one type of duct plate, for example by pressing, herz.ustel 1 en, there are large numbers of items and accordingly low prices. As when creating the pipeline system which are usually shown on a drawing Line connections directly on the duct plate are transferrable, namely by separating the bet! 'open Bridges between the channel pieces are errors in the Connection almost impossible. The unraveling is relatively easy and can ζ. Usually by milling or by breaking it out with a suitable tool. The effort to create a pipeline system is therefore extremely low, which also affects the adaptation of a system that has been created to new tasks, since the duct plate with the old cable routing quickly and easily can be replaced by a duct plate with the new cable routing is. New pressing tools, as they were required when replacing previous channel plates, are not required.

The creation of line systems is particularly cost-saving if the sections of the duct have Plate has dividing lines to which the regular repeating patterns are arranged symmetrically. One so-called Xonnplatte can then be fulfilled according to the Requirements can be used as a whole plate to create a desired line system, or only Parts of this plate, the division along the plate

this symmetry or TeüungsÜnien has to be done. In this way, a further saving in manufacturing costs and storage costs can be achieved.

According to a preferred embodiment of the invention the pattern repeated on both sides of the dividing lines is ladder-shaped. But it can also be comb-shaped or be designed in a meandering manner.

In order to facilitate the handling of the plate having the channel sections, it is provided with a fixed, pre-assembled plate preferably connected to a metallic base.

In the case of particularly extensive pipeline systems, it can be more appropriate for given space conditions, instead of the arrangement of the line system in one level of this ± n to subdivide several superposed levels.

The channel plate according to the invention is also suitable for this, without losing their beneficial properties. Such separated from one another by separable webs Channel sections having plate, the channel sections are arranged according to a regularly recurring pattern, has according to a further feature of the invention Channel sections that have openings penetrating the plate exhibit.

In this way, there is a pressure potential of a switching level to be transferred easily and safely to another switching level, namely the switching level below.

According to a preferred Ausführiingsform of the invention, the foraminous channel sections are arranged at such a distance from one another that they -from with the connections correspond through the pipeline system to be interconnected pneumatic or hydraulic components. Π Π QQ '9 / fl 7 "3 R

When arranging several duct sections in layers According to the invention, the load-bearing plates are each arranged between these plates, the open ones Further plates of the pipe system that cover channels and establish the connection between the individual channel levels Breakthroughs.

The property of the plates carrying the duct pieces as standard plates is therefore retained, since when they are arranged of the line system to be created in a single plane, the plate in a known manner between two metal plates is clamped, of which one plate is the switching elements and the other plate is the supply and discharge lines wearing. The in which the channel sections having The openings provided for the plate are thus closed in a pressure-tight manner by the plates carrying the supply and discharge lines. The same applies to the layered arrangement of the Plates carrying duct sections, here too are the Unnecessary openings in the plates are covered in a pressure-tight manner by the other plates made of metal.

In order to facilitate the creation of the breakthroughs, wear the other according to a further feature of the invention Panels are a network of lines showing all possible locations for openings to be made.

All details about the invention emerges from the description in conjunction with the drawing on which a Embodiment of the line system according to the invention is shown more or less schematically.
