Definitions

  • the invention relates to a vacuum generating device which operates according to the so-called ejector principle and serves to generate a negative pressure in a limited for example by a suction cup or a suction cup space for handling objects and deliberately reduce the negative pressure by a positive pressure pulse.
  • One from the German utility model 29903330 known vacuum generating device has a housing with inlet and suction ports arranged on opposite inlet and suction sides, wherein in the housing a between the ports interposed and transversely oriented suction nozzle device is housed, which can cause suction on the suction port.
  • a pressure accumulator is filled, which can provide a positive pressure pulse for venting the space to be evacuated, being used to control the overpressure pulse arranged in an extension of the suction nozzle valve, which is designed as part of an air-saving device.
  • the known device has a relatively bulky structure. It is therefore the object of the present invention to provide a vacuum generating device which can be realized with much more compact dimensions in order to favor installation in a confined space.
  • a vacuum generating device with a housing, which on one inlet side serves for feeding a fluidic pressure medium Having inlet connection and on one of the inlet side opposite suction side connectable or connected to a vacuum to be evacuated suction port has, arranged in the housing, with the same direction as a running between the inlet port and the suction port imaginary linear connecting line extending elongated suction nozzle means whose rectified as the inlet port oriented inflow opening is connected to the inlet port and the suction port is connected to the suction port, and the outflow port communicates with an outlet located at an outlet side of the housing oriented transversely to the imaginary connection line and at the same time transverse to the longitudinal extent of the suction nozzle device, and a longitudinal pressure pulse device arranged in the housing alongside the suction nozzle device with the same orientation as the latter and for generating a fluidic pressure pulse
  • For the space to be evacuated which includes a combined with a pressure accumulator shuttle valve having a first port connected to the in
  • a vacuum generating device results, which can be realized in a very slim, compact design.
  • the inlet port and the suction port face each other on opposite sides of the housing, wherein the suction nozzle device and the positive pressure pulse device with the same orientation as an imaginary connecting line connecting the inlet port and the suction port are accommodated alongside one another in the housing. Since the correspondingly placed overpressure pulse device also contains the pressure accumulator, it is possible to dispense with external accumulator measures, and all the components are combined in the smallest possible space. In connection with the overall rectilinear structure of the vacuum generating device also results in a good efficiency with low flow deflections.
  • the vacuum generating device is characterized by a very rapid reduction in vacuum in the evacuated space, since the pressure buildup in the pressure accumulator can cause an automatic switching of the shuttle valve in an interruption of the pressure medium supply due to the resulting change in pressure conditions, so that until then stored pressure medium flow to the suction port and can cause a short-term overpressure formation in the room to be evacuated.
  • this overpressure pulse can represent a dropping impulse which results in a quasi-sudden detachment of a hitherto still adhering object.
  • the inlet port and the suction port are placed on the inlet and suction sides, respectively, such that their longitudinal axes coincide and lie on the imaginary connecting line.
  • the space-saving juxtaposition of multiple vacuum generator devices is favored when the housing has an elongate shape, with the inlet side and suction side being formed by the two end faces of the housing and the outlet side by a sideways oriented longitudinal side of the housing.
  • the imaginary connecting line coincides with the longitudinal axis of the housing or extends at least parallel thereto.
  • suction nozzle device and the overpressure pulse device are arranged side by side with longitudinal sides parallel to one another. Their lengths suitably agree at least substantially in particular, they are at the same height with respect to the longitudinal direction of the housing.
  • suction nozzle device and the positive pressure pulse device are particularly simple if the associated components are accommodated in two side by side arranged receptacles of the housing.
  • one or both devices may be formed as cartridge-like units, which can expediently be inserted from an end opening into associated receptacles of the housing.
  • the inlet connection or the outlet connection are in particular equipped with plug connection devices which allow the connection of fluid lines as part of a plug-in installation.
  • the movable valve member is located between the two opposed valve ports, the second valve port being formed from the mouth of a tubular body and connected to the suction port through the tubular body and the accumulator being enclosed by a tube body Annular space is formed. In this way, a very space-saving and compact combination results between the shuttle valve and the pressure accumulator.
  • valve member with a closed bottom and a bending elastic sealing lip forming circumferential side wall, wherein the bottom serves as a closure part for the second valve opening and wherein the sealing lip against the inner surface of the first valve opening with the pressure accumulator connecting Transition space is biased and thereby projects in the direction of the pressure accumulator so that it can be bent inwardly from the over the first valve opening inflowing, under operating pressure medium and on the valve member takes place over a filling of the pressure accumulator.
  • the vacuum generator device 1 shown in the drawing has an elongate housing 2 with preferably cuboid outer contour.
  • the cross-sectional contour of the exemplary embodiment is held rectangular, wherein the Fig. 1 resulting cutting plane parallel to the large-area side surfaces of the housing 2 extends.
  • a round cross-sectional contour would also be possible with an externally cylindrically shaped housing 2.
  • the longitudinal axis of the housing 2 is indicated by dash-dotted lines at 3.

  • a connection of the inlet port 4 with a pressure medium source P can be produced, which is in particular a compressed air source.
  • the second fluid line 13 allows the connection of the suction port 6 with a space to be evacuated 14.
  • the latter is in the embodiment in the interior of a suction gripper 15 formed by a suction cup or a suction cup, for example, a vacuum handling device.
  • the suction gripper 15 can be set with its open side in front of an object to be handled, after which the space limited by the suction pad 15 and the other object of the subject 14 can be evacuated by the vacuum generator device 1 to a negative pressure-related adhesion of the article to the suction pad 15th to effect.

  • the suction nozzle device 16 still has an outflow opening 32 which is connected to an outlet 33 of the housing 2 which opens out to the outer surface of the housing 2 and thus leads to the atmosphere.
  • the corresponding outlet side 34 of the housing 2 is oriented transversely and preferably at right angles to the imaginary connecting line 18 and at the same time transversely to the longitudinal axis 17 of the suction nozzle device 16. In the exemplary embodiment, it is formed by a longitudinal side of the housing 2 extending between the two end faces.
  • a positive-pressure impulse device 35 which likewise has an elongate shape, is accommodated alongside the matching alignment. It makes it possible to generate a fluidic overpressure pulse for the space 14 to be evacuated.

  • the two inflow channels 25a, 25b at least partially coincide.
  • One of the first valve opening 43 in the direction of the longitudinal axis 36 at a distance from the opposite second valve opening 44 of the shuttle valve 38 is connected via a likewise extending in the interior of the housing 2 pulse channel 45 with the suction port 6 in connection.
  • the pulse channel 45 and the suction channel 28 may also be at least partially also formed by a common fluid channel.
  • transition space 46 Between the two valve openings 43, 44 there is a space designated as transition space 46, in which the valve member 47 of the shuttle valve 38 is located. This is between a second valve opening 44 releasing open position and a second valve opening 44 tightly closing Closed position movable.
  • the open position of the valve member 47 is off Fig. 1 as well as in solid lines Fig. 3 seen.
  • the closed position results Fig. 2 as well as from the dot-dashed representation of Fig. 3 ,
  • the direction of movement of the valve member 47 coincides with the orientation of the longitudinal axis 36.

  • the transitional space 46 is immediately adjacent to the annular space 53.
  • the annular space 53 and the transition space 46 circumferentially limiting and uniformly provided with reference numeral 54 boundary surfaces are expediently directly into each other.
  • the preferably used valve member 47 has an integrated non-return function. It has according to Fig. 1 and 2 a pot-like structure with a perpendicular to the longitudinal axis 36 extending bottom 55 and a projecting from the edge of the bottom in the direction of the pressure accumulator 37 circumferential side wall, which is designed as a radially elastically deformable sealing lip 56.
  • the sealing lip 56 is located in the Fig. 1 Resulting basic position on the associated boundary surface 54, which also conveniently without fluidic pressurization is given a certain radial bias.
  • control valve 57 is interposed in the connection between the pressure medium source and the inlet port 4.
  • a designed as a 3/2-way valve control valve 57 is indicated, which has two possible switching positions, it either the connection between the pressure medium source P and the inlet port 4 releases or causes an interruption of the connection, while establishing a connection between the inlet port 4 and the atmosphere R.
  • a simpler 2/2-way valve for selectively enabling or interrupting the connection without simultaneous venting would be possible.
  • the pressure medium flows through the suction nozzle device 16, wherein it first passes through a jet nozzle channel 58, in which it is accelerated to supersonic, then subsequently, after bridging a gap 59, enter into a catching nozzle channel 60, which leads to the outflow opening 32. From there, the pressure medium flows via the outlet 33 into the open.

  • the latter is characterized in the Fig. 2 displaced outgoing closed position, wherein it shuts off the second valve opening 44.
  • the pressure medium causes bending of the sealing lip 56 radially inward, so that these according to Fig. 2 is lifted from the associated boundary surface 54 and the pressure medium, on the outer circumference of the valve member 47 past, can flow into the annular space 53 of the pressure accumulator 37.
  • the pressure accumulator 37 is filled with pressure medium until a storage pressure corresponding to the actuation pressure is present.
  • the valve member 47 remains in the closed position.
  • the force acting in the closing direction is determined by the overpressure acting on the first loading surface 64 and by the negative pressure acting on the second valve opening 44 on the second loading surface 65 of the valve member 47 which covers it.
  • the force acting in the opening direction is determined by the annulus 53 facing annular third loading surface 66 of the valve member 47 in conjunction with the ruling in the annular space 53 pressure.
  • a comparable overpressure pulse occurs when a control valve 57 without venting function is used.
  • the pressure drop in the area of the first loading surface 64 then results exclusively from the connection of the first valve opening 43 with the outlet 33 open to the atmosphere via the suction nozzle device 16.
  • the overpressure pulse can therefore also be referred to as a discharge pulse.
  • throttling device 67 is variably adjustable in the generated throttling intensity to adjust in this way the intensity of the pressure pulse or the speed of pressure build-up in the previously evacuated space 14 as needed.
  • the vacuum generator device 1 has a particularly advantageous housing construction.

  • the suction nozzle device 16 has a cartridge-like structure and is used as a structural unit in the associated receptacle 70.
  • the outflow opening 32 communicates over a partial region of the receptacle 70 with the outlet 33, which here is formed by a partial opening of the peripheral wall delimiting the receptacle 70.
  • the pressure-impulse device 35 is designed so that the boundary surfaces 54 are formed directly by the lateral surface of the associated receptacle 71.
  • the tubular body 72 is part of an insert 74, which with a holding portion 75 corresponding to the diameter of the receptacle 71 is inserted into the respective receptacle 71 in advance, from which the tubular body 52 protrudes toward the inlet side 5.
  • the tubular body 52 is slightly shorter than the receptacle 71, so that between the end of the tubular body 52 and the attached cover part 69 remains a distance which defines the transition space 46, in which the valve member 47 is inserted.
  • Both the suction nozzle device 16 embodied as a structural unit and the insert part 74 of the overpressure pulse device 35 are provided on the circumference with seals in order to ensure the necessary sealing to the housing 2.
