Definitions

  • the invention is based on a modular support block for electromagnetic directional valves according to the preamble of claim 1.
  • the electromagnetic directional control valves mounted on the individual support bodies have a predetermined output function in their mounting position, either normally closed or normally open.
  • a disadvantage of these carrier blocks is that two different versions of a valve type are required if one or some of the valves of the carrier block are to have a different output coding than the other valves of the same carrier block.
  • Another disadvantage is that if a directional valve is defective when replacing it, care must be taken that a valve with the correct output function is installed again. This in turn means that two different valve versions of the same valve type are in stock must be kept and that the fitter must carefully select the correct valve so that there is no confusion.
  • the object of the invention is to improve a modular support block of the type mentioned for electromagnetic directional control valves in that it is designed such that each directional control valve assigned to its individual support body of the same type can be operated in two output codes.
  • the carrier body according to the invention makes it possible for a directional valve of the same type, preferably a 3/2-way valve, but also a 2/2-way valve, to be fastened to the carrier body and nevertheless one or the other coding of this valve as an output coding can be used.
  • Either the “normally closed” or “normally open” coding of the directional control valve can be used as the output coding.
  • the P and R connections of the turned carrier body are interchanged with the P and R connections of the carrier bodies adjoining it, so that a normally closed valve can be operated in a normally open starting position when control fluid pressure is present.
  • the carrier block according to the invention consists in that its carrier bodies are each provided with a plug connection formation for their connection to one another, which is constructed in such a way that the reversed arrangement of carrier bodies is secured by 180 ° in the position according to the invention.
  • the plug-in connection formation can consist of two molded connections of the dovetail type provided on both sides of a central plane on the underside of the carrier bodies, each molded connection consisting of a receiving section and a laterally projecting section.
  • One protruding portion protrudes to one side and the other protruding portion protrudes to the other side of each support body.
  • the molded connections can also be provided with locking elements. In this way, a simple and secure releasable connection of the carrier bodies of a carrier block to one another is achieved.
  • a support block 1 shown in perspective shows a support body 2 on its own, while the remaining support bodies 3 and 4 are shown in the state in which they are assembled into a row. How many carrier bodies are selected depends on the units to be controlled at the place of use; a corresponding number of carrier bodies is accordingly selected.
  • Known feed elements 5 are provided at the two ends of the carrier bodies which are put together to form a block, in order to operate the individual carrier bodies of the carrier block with one or more control fluids. This can be done in a known manner so that, for. B. two inner carrier bodies of the carrier block can be fluidically separated from one another by a known sealing arrangement, so that both end-side feed elements 4 can be supplied with different control fluids, these fluids also being able to have a different pressure.
  • the top of the carrier body is equipped with electromagnetic directional control valves 6 and 7.
  • so-called 3/2-way valves and 2/2-way valves are preferably used.
  • the structure and function of these valves are known and are therefore not explained in detail.
  • each carrier body has a first channel section 8 and a second channel section 9 for the passage of control fluid, the sections 8 and 9 of all adjoining carrier bodies each forming a common straight passage channel through the carrier block, which is connected to the corresponding fluid conduction paths communicated in the feed elements 5.
  • the channel section 8 or the channel section 9 can optionally act as a supply channel, while the other channel section then takes over the discharge of the control fluid.
  • Secondary passages 10 and 11 run from the channel sections 8 and 9 to the upper side of the carrier body, where they are aligned with the corresponding inputs and outputs 12 of the electromagnetic directional control valves 6, 7 attached. Between the two channel sections 8 and 9 runs a working channel 13 for the control fluid, which is also aligned on the valve side with an outlet 12 and on the other hand communicates in a known manner with two end outlets 14.
  • the directional valve 6 indicated in FIG. 3 is a 3/2-way valve which is in the closed position when de-energized. Furthermore, it is assumed that all adjacent first channel sections 8 form a supply channel P, while the second channel sections 9 form a ventilation channel R. If the directional valve 6 is now energized, the control fluid of the channel P via the valve 6 into the working channel 13 and from there via the usual connections and lines to the unit to be controlled (not shown). If the power supply to the valve 6 is switched off, it can be vented via the working channel 13 and the valve 6 in the usual way via the ventilation channel R.
  • the carrier body 6 is now mounted within the carrier body row 1 turned through 180 °, as is shown in FIGS. 1 and 2 can be seen where the turned carrier body is marked with 4, the associated directional control valve 7 also being turned over, since both parts 4 and 7 form a unit, it is clear that the same directional control valve now has a different output function.
  • the channel sections 8 and 9 of the support body which is turned through 180 °, are practically interchanged, so that the second channel section 9 is now fed with the inflowing control fluid from the channel P, while the first channel section 8 is converted into a venting channel section.
  • the electromagnetic directional control valve if it is not yet energized, is practically in an open initial state via its own internal, uninterrupted R-A connection, so that the normally closed valve has become a quasi normally open valve.
  • the plug-in connection design consists of two molded connections 17, each with the same distance on both sides of a common plane 17 provided on the underside of the carrier body and running centrally between the two channel sections 8 and 9 of each carrier body.
  • the molded connections are designed, for example, according to the generally known dovetail design, as the figures clearly show, so that there is only one explanation of this form of connection required for the present purpose.
  • each molded connection 17 consists of a receiving section 19 and a section 20 projecting laterally from the support body 3. Furthermore, the two molded connections 17 of each support body 3 are arranged in opposite directions, as shown in FIGS. 1 and 5 clearly show that one projecting section 20 projects to one side and the other projecting section 20 projects to the other side of each carrier body.
  • the receiving sections 19 of each molded connection 17 are provided in the correct direction directly on the underside of the carrier body.
  • the molded connections 17 are provided with a latching device 21, 22, 23.
  • the receiving sections 19 of the molded connections are provided with a spring tongue 21 with a catch 22, while the laterally projecting sections 20 have a catch hole 23. It can be seen particularly well from FIG. 5 that when two carrier bodies 3 are plugged together, the latching lugs 22 of one carrier part 3 snap into the associated latching holes 23 of the other carrier body 3.
  • the electromagnetic directional control valves 6, 7 are provided with the usual electrical connection contact 24.
  • a common and standardized electrical connection strip (not shown) is generally used, which is plugged onto the contact pins 24.
  • the distances between the contact pins 24 are also in standardized to a grid dimension.
  • the usual grid dimension in electronics is 2.54 mm.
  • the width of the directional control valves is generally one grid dimension larger than the distance between their contact pins 24. It is therefore advantageous to also produce the width of the carrier bodies 2, 3, 4 in a grid dimension that corresponds to that of the directional control valves.
  • the grid dimension for the carrier body is designated B in FIG. 5 and corresponds in the case shown to four times the grid dimension, for example, so that the carrier body 3 has a width of 10.16 mm.
