Definitions

  • the invention relates to an electropneumatic valve assembly according to the type specified in the preamble of claim 1.
  • Such an electropneumatic valve assembly is already known from EP 0 413 960 A1, in which a plurality of valve arrangements are arranged in parallel next to one another on a base plate through which pressure medium channels pass.
  • Each valve arrangement consists of a main valve and two electromagnetic control units arranged on the front, which are mounted together on the base plate via an adapter plate.
  • the adapter plate in which there are flow channels for the pressure medium, electrical lines for the electromagnetic control units are laid and it has two flexible intermediate areas with which the adapter plate can compensate for large tolerance ranges.
  • the base plate which is traversed by the pressure medium channels, is formed in one piece and is limited in length to a certain number of valve positions, so that the number of possible control functions is also limited. It is therefore not possible to achieve an optimal design in certain applications, e.g. if a different number of ways would be required instead of the 5-way valve series.
  • an electropneumatic valve assembly is known from DE 40 04 834 A1, in which an intermediate adapter plate is arranged between a base plate and a main valve. In addition to pressure medium-carrying working channels and fluidic control channels, this adapter plate also receives electrical lines which connect the electromagnetic control units to an electrical connection of the base plate.
  • the electromagnetic control units are integrated in fluidic pilot valves, which are flanged to the adapter plate at the end.
  • the disadvantage of this valve assembly is that the adapter plate is complex to build and is only suitable for the same valve series. A base plate with several valve positions is also missing here.
  • the main valve of the valve assembly is actuated fluidically, the control valves flanged on the end face of the adapter plate merely taking on pilot control functions. The use of different valve series is also not possible here.
  • the electropneumatic valve assembly according to the invention for mounting on a base plate with the characterizing features of the main claim has the advantage that different valve series can be used together on the same base plate, so that a mixed valve series is created.
  • connection plate With the help of the connection plate, one or two 3/2-solenoid valves can be arranged on a valve position on the base plate, so that installation space and costs are saved and more control functions can be accommodated in the same existing installation space. It is particularly favorable if 5-way valves and 3-way valves are mixed in the valve block. The advantages of the flexible adapter plate can be retained without restriction.
  • FIG. 1 shows a partial longitudinal section through an electropneumatic valve assembly according to the invention attached to a base plate, part of which is shown in section
  • FIG. 2 shows a plan view of the base plate with the attached electropneumatic valve assembly according to FIG. 1
  • FIG. 3 shows a side view of the base plate with the assembled Valve assemblies according to arrow direction A in Figure 2.
  • an electropneumatic valve assembly 10 is shown partially in longitudinal section, which is attached to a valve location on a base plate 11.
  • a first longitudinal duct 12 for supplying pressure medium to the supply air and the second or third longitudinal duct 13, 14 are connected to the exhaust air.
  • transverse channels 15, 16 and 17 each lead into a connecting surface 18 of the base plate 11 and form a valve location 19 there.
  • the valve assembly 10 arranged on the valve location 19 consists of
  • connection plate 21 essentially consisting of a multi-unit adapter plate 21 resting on the connection surface 18, a cuboid connection plate 22 fastened to the adapter plate 21, the two 3/2-solenoid valves 23 and 24 fastened to the end faces of the connection plate 22 and their associated electromagnetic control units, which are designed here as magnets 25 or 26.
  • the connection plate can be made of metal or plastic.
  • the adapter plate 21 has one per se
  • Known type in which there are three through holes 28, 29, 31 in a base part 27, which communicate with transverse channels 15, 16 and 17 in the base plate 11.
  • the base part 27 merges at its two outer ends via an elastic region 32 into an external connection part 33 and 34, respectively.
  • the two connection parts 33, 34 are connected to one another via electrical lines and have suitable plug connections in a manner known per se, so that they can each be connected to the electrical plug contacts of the magnets 25 and 26, respectively.
  • a screw connection 35 ensures sufficient mechanical fastening between the magnet and the associated connecting part.
  • 33 plug contacts 36 are formed in the region of the first connecting part, with which the adapter plate 21 can be connected to an electrical connector strip 37 in the base plate 11.
  • the magnets 25, 26 are screwed in the usual way to the solenoid valves 23 and 24, which in turn are fastened to the connecting plate 22 in a manner known per se.
  • Commercially available components can be used for the magnets 25, 26, in which a longitudinally movable armature is used to actuate a control element in the solenoid valve 23 or 24.
  • Commercially available components can also be used for the solenoid valves 23, 24, each of which has a 3-way, 2-position function, so that they can either connect a work connection to the supply air or vent it.
  • connection plate 22 is adapted to the given conditions by adaptation.
  • the cuboidal connection plate 22 has two opposite end faces 38, 39, into each of which two pressure medium channels 41, 42 and 43, 44 open.
  • the solenoid valve 23 attached to the first end face 38 controls the connection between the two pressure medium channels 41, 42, while the second solenoid valve 24 attached to the second end face 39 controls the connection between the two channels 43 and 44.
  • the connection plate 22 has on its upper connection surface 45 two consumer connections 46, 47, of which the first 46 is connected to the pressure medium channel 41, while the second consumer connection 47 is connected to the channel 43.
  • the two other pressure medium channels 42 and 44 lead to an inlet channel 48 which is designed as a blind hole and which is open to a flange surface 49 formed at the bottom of the connection plate 22 and has a connection to the through hole 28 in the adapter plate 21.
  • the adapter plate 21 has a blind hole 51 in the flange surface 49, into which a pin 52 engages in order to center the connection plate 22 relative to the adapter plate 21 and sits in the third through hole 31 of the adapter plate 21.
  • the connection plate 22 is further delimited by two mutually parallel side walls 53, so that the thickness of the connection plate 22 is adapted to the width of the adapter plate 21 and thus to the available space at the valve location 19.
  • FIG. 2 shows a top view of base plate 11 with valve assemblies mounted on it
  • FIG. 3 shows a side view of base plate 11 in the direction of arrow A according to FIG. 2.
  • the base plate 11 has a total of 6 valve positions, of which the second valve position 19 is occupied by the electropneumatic valve assembly 10.
  • a 5/2-way valve 54 which is designed as a changeover valve, is mounted on a first valve position of the base plate 11, while a 5/3-way valve 55 is arranged on the third valve position.
  • the fourth valve position of the base plate 11 is covered by a blind plate 56, while the fifth and sixth valve positions 57 and 58 are shown as not occupied.
  • FIG. 2 in conjunction with FIG.
  • valve assembly 10 and the 5/3-way valve 55 are each mounted via adapter plates 21, which are identical to one another.
  • the 5/2-way valve 54 can be attached directly to the base plate 11 without an additional adapter plate.
  • the two directional control valves 54 and 55 are also connected to the electrical plug connector 37, which in turn is in an electrically conductive connection in a manner known per se with the central plug 59.
  • the mode of operation of the electropneumatic valve assembly 10 is explained as follows, the basic function of such valve batteries in which a plurality of directional valves or valve assemblies are arranged on a base area 11 being assumed to be known per se.
  • Mixed valve arrangements can be realized with the electropneumatic valve assembly 10 on a common base plate 11.
  • directional valves 54, 55 of the same valve series equipped, namely with 5-way valves 19 valves of another series can be accommodated in the second valve position, namely 3-way valves.
  • a mixed valve arrangement can therefore be achieved with which certain control functions can be better performed.
  • each solenoid valve 23 or 24 can either connect its associated consumer connection 46 or 47 to the inlet channel 48 or relieve it from the outside air. The ventilation takes place via an outlet, not shown, in the solenoid valves 23 or 24 to the outside air.
  • valve assembly 10 can be mounted inexpensively, since the connection plate 22 can be attached to the adapter plate 21 in a simple manner and the assembly of the commercially available solenoid valves 23, 24 or the magnets 25 or 26 is carried out as usual.
  • the electropneumatic valve assembly 10 can be arranged at any valve location on the base plate 11. Although it is particularly advantageous to install two 3/2-way solenoid valves on the connection plate 22, one of the two solenoid valves can also be omitted if necessary and thus only one control function can be used. Instead of the 5-way and 3-way valves shown, other valve series can also be mixed in a corresponding manner.
