Definitions

  • Such devices are approximately from the AT 8634 U1 known and come in sorting machines for transparent and non-transparent bulk materials such as metals, plastics, rocks and glass, paper or cardboard used. They work preferably by means of optical or inductive transmitter and receiver units and serve to remove foreign matter located in the material flow from the material flow or to convey different types of the material of the material flow into different containers.
  • the transmitter units consist for example of light rays emitting light sources, preferably diode light sources, which are bundled in the receiver unit via a lens system on a photocell.
  • light sources preferably diode light sources
  • embodiments are also known in which color cameras are used as receiver units and as Light sources conventional light sources such as fluorescent tubes act.
  • Both transmitter and receiver units are connected to a central processing unit, which processes the incoming data and, due to the intensity of the incident on the receiver unit and radiated by the transmitter units light beams to detect location, size and type of individual pieces located in the material flow.
  • the sorting of the individual pieces is carried out in dependence on the successful detection of the individual pieces in the material flow.
  • a gaseous or liquid medium for example compressed air or water
  • a conventional solenoid valve usually consists of a valve stem and a return spring, to reset the valve stem and an electromagnet, which causes the opening movement of the valve stem. Return spring and electromagnet are due to the operation of the Valve, each seen on different sides of the valve stem with respect to the axis thereof, arranged.
  • control electronics opens the solenoid valve, a compressed air flow builds up from the valve seat in the flow channel in the direction of the nozzle mouth. Due to the abrupt closing when the solenoid valve is switched off, a vacuum or negative pressure is generated in the flow channel due to the inertia of the air column. As a result, small dust particles are sucked into the flow channel. If they reach the valve stem of the solenoid valve, they cause additional friction and, as a result, increased wear. This reduces the life of the solenoid valves.
  • the DE 10 2008 050 907 A1 discloses the preamble of claim 1.
  • the DE 10 2008 050 907 A1 shows two variants of dust protection means between the outlet opening of the exhaust nozzles and the valves of a blower: a first variant comprises a cavity, seen from each of the exhaust nozzles in the direction of fall, the nozzle subsequent to the nozzle supply line extends to the bottom of the cavity. At a distance above the ground a Querzumol ein opens into the Düsenzumoltechnisch. This ensures that penetrating dust particles do not penetrate to the valves, but deposit below the mouth of Querzu slaughter endeavor in the cavity.
  • This first variant has the disadvantage that the nozzle supply line adjoining the nozzle must always be arranged vertically in order to deposit dust particles that penetrate. In addition, increases by the distance of the transverse feed bore to the bottom of the cavity, the volume of the nozzle supply line and the space required.
  • the second variant of dustproofing the DE 10 2008 050 907 A1 comprises for each exhaust nozzle a valve-free bypass line, via the compressed air when the main body of the blower permanently compressed air flows to the exhaust nozzles.
  • a valve-free bypass line via the compressed air when the main body of the blower permanently compressed air flows to the exhaust nozzles.
  • At least one connecting channel branches off from a plurality of flow channels, which opens into at least one pressure reservoir common to the connecting channels, which is sealed gastight and / or liquid-tight except for the connecting channels and the pressure reservoir communicates only through the connecting channels through that medium through which the Anblasdüsen associated valves, preferably solenoid valves, has flowed, acted upon, can.
  • the pressure reservoir, the connection channels and the flow channels are formed so that when opening one or more valves medium from each open valve through the associated flow channel and the one or more branching from this flow channel connecting channels flows into the pressure reservoir, while the same medium from the pressure reservoir flows through one or more other connecting channels in those or those flow channels whose valve is closed.
  • connection channel Preferably, exactly one connection channel will branch off from each flow channel of a device according to the invention and all flow channels of a device will have a connection channel. But it is also conceivable that only some flow channels have such a connection channel. Independently of this, it would also be possible to provide a plurality of connection channels per flow channel, which lead into the same pressure reservoir. Or it could lead to different connection channels of a flow channel in different pressure reservoirs.
  • a compressed air partial flow is branched off from those flow channels which are currently exposed to compressed air and passed into the pressure reservoir, which thus serves as a compressed air reservoir. If the solenoid valve of the previously acted upon with compressed air flow channels closed, is sucked by the resulting vacuum or negative pressure pure compressed air from the pressure reservoir through the connecting channels and no longer contaminated ambient air through the nozzle mouth. This increases the service life of the solenoid valves.
  • connection channels or the pressure reservoir consumes no compressed air, it is only in valve activity in operation. There must be - due to the lack of moving parts - no maintenance of the connecting channels or the pressure reservoir.
  • a good effect according to the invention is provided if the cross-sectional area of the connecting channels is 5-10%, in particular about 6.5%, of the cross-sectional area of the nozzle mouth of the blowing nozzles. As a result, less than 10% of the air that passes through the solenoid valve in the flow channel, in the connecting channel and in the pressure reservoir.
  • the volume of the pressure reservoir is usually greater than the common volume of all flow channels. If the pressure reservoir is designed as a simple bore, then its diameter is usually larger by a multiple than the diameter of a flow channel.
  • the flow channel causes a, in particular only a single, deflection of the gaseous medium and the connecting channel branches off in the region of this deflection of the flow channel, in particular in the direction of the medium before the deflection (relative to the flow direction of the medium in the operating state, if it flows from the valves to the blowing nozzles).
  • the flow channel consists of a first straight section, starting at the valve seat of the valve, and a second straight section, which in an angle between 0 and 180 °, in particular at an angle of 90 °, to the first section, and the longitudinal axis of the connecting channel coincides with the longitudinal axis of the first straight section.
  • the first straight portion begins at the valve seat, follows the longitudinal axis of the valve seat and ends at the deflection.
  • the second section begins at the deflection and ends at the nozzle mouth of the blowing nozzle.
  • the deflection is designed so that the second section in the region of the deflection at least over the longitudinal axis of the valve seat or the first section.
  • valve stem of the valve if this is screwed approximately into the device, substantially perpendicular to the Anblasdüse or to the second portion of the flow channel. Otherwise, the valve stem of the valve will enclose an acute angle with the axis of the blowing nozzle or with the second portion of the flow channel.
  • the design that the pressure reservoir next to the connecting channels has a closable connection for the supply of gaseous or liquid medium could be used to fill the pressure reservoir from outside the device with medium and to ensure that the pressure in the pressure reservoir is always high enough.
  • medium such as compressed air
  • the blowing device according to the invention can be operated with compressed air.
  • each valve can be assigned a Anblasdüse.
  • This variant makes it possible, given the number of blowing nozzles, to achieve the highest resolution or blowing precision. But it would also be possible for a valve to supply several blowing nozzles. By controlling multiple Anblasdüsen by means of a valve a simplified control is possible.
  • a particularly compact design for a device according to the invention is achieved when the Anblasdüsen, the valve stem including the valve seat, the at least one connection port, the flow channels, the connecting channels and the pressure reservoir are housed in a single housing.
  • the housing may have approximately the shape of a cuboid.
  • Another embodiment of a device according to the invention provides that the Anblasdüsen, the at least one port, the flow channels, the connecting channels and the pressure reservoir are housed in a single housing, while the valve stem and valve seat of the valves are outside the housing.
  • the pressure reservoir can most easily be designed as a cylindrical bore, but other shapes and production methods of a cavity can also be used.
  • the subject invention is basically used in all generic devices for blowing (valve blocks).
  • a possible method for operating a device provides that the pressure reservoir is acted upon via the connecting channels by that medium which has flowed through the valves associated with the blowing nozzles, preferably solenoid valves. It is not excluded that the pressure reservoir at least temporarily additional medium is fed through a - different from the connection channels - closable connection.
  • the method is designed so that the pressure reservoir is closed gas-tight and / or liquid-tight except for the connecting channels and the pressure reservoir is acted upon only via the connecting channels by that medium which has flowed through the valves associated with the blowing nozzles, preferably solenoid valves.
  • Fig. 1 shows a Anblasvoroplasty invention, consisting of a cuboid housing 12 whose walls are transparent here in order to recognize the arrangement of the individual elements inside.
  • the housing 12 is preferably made of aluminum. Alternative materials However, such as steel, stainless steel, brass or plastic can also be used.
  • compressed air is introduced into the housing 12 via the connection opening 1, which opens into a supply chamber 2, which extends in the housing transversely to all - in this case twelve - solenoid valves 3.
  • Six solenoid valves 3 are arranged on the top of the housing, six on the back.
  • the valve seat and the valve stem of the solenoid valves 3 are located outside the housing here.
  • the direction of movement of the valve stem may, for example, be parallel to the surface of the housing 12, ie normal to the subsequent flow channel 4 located in the housing 12. However, the direction of movement of the valve stem may also be normal to the surface of the housing 12, ie in the direction of the adjoining flow channel 4 ,
  • the compressed air is evenly distributed to all the solenoid valves 3 by each a compressed air line 11 leads from the supply chamber 2 to a solenoid valve 3. This can open, whereby compressed air enters the respective flow channel 4.
  • One type of flow channels 4 which are assigned to the solenoid valves 3 on the back, consists of a straight first section (here perpendicularly oriented from back to front), which at a right angle into a straight second section (here down) passes to into a Anblasdüse 7 (not visible here) to open at the bottom of the housing 12.
  • a straight first section here perpendicularly oriented from back to front
  • a straight second section here down
  • Anblasdüse 7 not visible here
  • the second type of flow channels 4, which are assigned to the solenoid valves 3 on the top, is just (here from top to bottom) in the Anblasdüse 7 on the underside of the housing 12, about in the last quarter a connecting channel 5 branches off at right angles into the common pressure reservoir 6.
  • the Anblasdüsen 7 can be designed as its own, screwed about, components, but they can also be easily realized by the last part of the flow channel 4 or by its exit from the housing, see Fig. 2 ,
  • a housing 12 is provided with eight solenoid valves 3, the electromagnets 3 are arranged at the top of the housing.
  • the electromagnets are screwed into the housing 12 and actuate the valve stem, which move in the vertical direction (normal to the surface of the housing 12), but are not visible here.
  • the valve seat is provided in the housing 12.
  • the straight flow channels 4 here form an acute angle with the direction of movement of the valve stem. It is provided for all flow channels 4, a common pressure reservoir 6 in the form of a bore, which also runs normal to the flow channels 4, almost over the entire length of the housing 12.
  • holes 10 which are tightly closed in this embodiment by means of threaded pins or metal balls, so do not represent a connection with the outside space.
  • the pressure reservoir 6 are acted upon only via the connecting channels 5 with gaseous or liquid medium, or can escape only via the connecting channels 5 gaseous or liquid medium from the pressure reservoir 6.
  • a compressed air partial flow is diverted from those flow channels 4, which are currently subjected to compressed air, and fed into the pressure reservoir 6, which thus serves as a compressed air reservoir. If the solenoid valve 3 of the previously acted upon with compressed air flow channels 4, is sucked by the resulting vacuum or negative pressure pure compressed air from the pressure reservoir 6 through the connecting channel 5 and no longer contaminated ambient air through the nozzle mouth of the Anblasdüse 7. From a certain on-time The saturation of the solenoid valves 3 per minute is reached, the pressure in the pressure reservoir 6 will not increase any further, because of the counterpressure less medium flows from the flow channels 4 into the connection channels 5, the volume of the branched medium therefore drops.
