Definitions
- the invention relates to a method for funding a powdery good according to the preamble of Claim 1 and an injector arrangement according to the preamble of claim 7. Furthermore, the invention relates to a Use of the injector arrangement according to claim 11.
- the setting of conveying air and dosing air which is a conventional one Compressed air source are removed so far either through separate control valves or through two valves arranged on a common shaft, see above that only one adjustment knob for adjusting both valves had to be operated.
- the powder-air mixture is a relative cover a long route to the coating point must (e.g. a path of 1 meter or more) or where a very homogeneous powder-air mixture is required has the previous setting of conveying air and dosing air proven to be very difficult.
- the can bodies are promoted e.g. at a rate of 18 doses per second (or at one Standard can size with approx. 100 m / min), which is only possible short-term fluctuation of the homogeneity of the powder-air mixture or the absolute amount of powder in one large number of insufficiently coated cans can.
- the invention is therefore based on the object to enable coating by means of an injector, where these disadvantages do not occur and in which even in very delicate conditions, especially in the welding seam coating of can frames, excellent coating quality can be achieved.
- This task is carried out in a process of initially mentioned type solved in that the second Gas flow is fed into the intake area.
- Effective vacuum in the suction area changed so that by the gas flow the amount of the powder sucked in can be determined.
- the amount of feed gas can remain unchanged. It has shown, that in this way an even and stable Delivery of the powder also achieved via long lines can be.
- the gas flow is in the same Direction as the conveying gas flow is introduced into the intake space and more preferably by an annular one Gap around the nozzle of the conveying gas flow, so that this is surrounded by the gas flow.
- an introduction to Gas flow transversely to the conveying gas flow i.e. at an angle to it or at a 90 ° angle is possible.
- the task begins with an arrangement of the mentioned type by the characteristic features of claim 7 solved.
- the method is preferred or the arrangement when coating can frames used for another purpose and for another good to be funded is also possible.
- the example of a well-known injector Injector 1 of FIG. 1 shown according to the prior art has a housing 12.
- the injector room 5 formed, into which the nozzle 4 of the injector protrudes.
- the nozzle 4 with gas in usually fed with compressed air, this compressed air flow forms the conveying air flow.
- the injector room 5 opens a connection 6, through which from a reservoir (not shown) the goods to be funded in the injector room is delivered, in which due to the Conveying air jet there is a negative pressure. That to be funded
- the flow of conveying air entrains well.
- the conveying air flow passes through a sleeve 7.
- connection 8 for the dosing gas in the housing 12 is also usually compressed air is.
- the metering air is the room 10 fed into which the conveying air flow also enters. The both air flows combine and leave the injector 1 through the connector 11 to which a line is connected, the powder-air mixture to the application site leads.
- the coating powder through the injector with Air pressure (e.g. in the range of 6 to 10 bar) in one line promoted in a known manner in the round apparatus enters the can welding machine, the welding area happens and then flows into a nozzle that the Powder-air mixture on the inside of the can weld sprayed on to coat them.
- the coating powder usually electrostatically charged.
- the coating powder becomes a coherent after cooling solid seam coating achieved.
- Corresponding coating powder are known and commercially available and the coating process is known as such. As before mentioned is the setting of conveying air and dosing air very delicate, so enough powder homogeneous distributed at sufficient speed (approx. 12 m / sec) the nozzle is conveyed to an even coating to reach.
- FIG. 2 now shows an injector arrangement as Embodiment of the invention or for explanation of the inventive method.
- an injector 21 provided with a housing 22.
- the injector room 25 formed in the nozzle 24 of the injector protrudes.
- the nozzle 24 is connected via the connection 23 fed with the conveying gas stream, usually from a Compressed air source 30 by means of a line 32, which in Figure 2 are only indicated schematically.
- the injector room opens a connection opening through which a storage container, not shown, the powder to be conveyed is delivered into room 25.
- the injector room 25 there is a negative pressure due to the conveying gas flow, which sucks in the powder to be conveyed, and this becomes entrained by the conveying gas flow.
- the conveying gas flow passes with the powder through a connector 31 on which the line 33 is connected to the powder-air mixture leads to the application site, preferably how already described at the seam area of welded Can frames.
- a second gas stream introduced into the suction area of the injector. in the 2 is a connection 36 provided in the injector housing 22, on which one is not shown gas line or compressed air line connected is.
- This line can be powered from the same source 30 be.
- the connection leads 36 to a part of the Connection 23 circumferential annular space 37, from which a annular gap 38 leads into space 25.
- the gap is formed in the example shown by a sleeve 39, which are at a predetermined distance from the front ones Surrounds the nozzle-containing part of the connector 23.
- the gap 38 in the gas flow 41 entering the injector space surrounds the conveying gas flow 40 ( Figure 3).
- the gas flow Affects the amount of powder sucked into the injector chamber 25, with more air supply in the gas stream 41 the Amount of the suctioned or conveyed with the injector Powder reduced and less air supply to stream 41 the amount of powder delivered increases.
- hiring the air supply at connection 36 or into the room 25 can thus with no change in the conveying gas flow delivered powder quantity can be set.
- the as Example shown arrangement can by a supply of approx. 0% to 15% air as gas flow 41 to that as 100% assumed gas flow 40 a sufficient variation the amount of powder conveyed can be achieved.
- the funded The amount is 100% powder with 0% gas flow 41 and approx.
- FIG 4 shows schematically a pneumatic diagram with the injector 21 shown therein as a block with the Conveying air connection 23 and the gas flow connection 36
- Conveying air and the gas stream air come from one only schematically illustrated compressed air source 30 to which via a line 45 a control valve 46 is connected, the a constant amount of air at its outlet line 47 delivers.
- the amount of air can be controlled by an electrical control signal via the control line 48 from a controller (not shown) can be specified.
- the valve 46 holds then the amount of air emitted by him automatically.
- a valve also known as a mass controller e.g. the mass flow controller type F 201 C from Bronkhorst, the Netherlands.
- a switchable Valve 50 may be arranged as the main valve through which the air supply to the conveying air connection 23 of the injector can be switched on and off.
- the mass controller 46 The air volume delivered then passes via line 51 and Check valve 52 to the supply air connection 23 of the injector 21. Branches upstream of the control valve 46 for the conveying air a line 54 to a flow meter 55 from a Has adjusting member 56, with which the amount of passed Compressed air is adjustable.
- controller 55 can a commercially available flow meter from Vögtlin AG, Switzerland. With the adjusting member 56 the amount of air emitted is set, which is above the Line 57 arrives at the connection 36 of the injector 21 and there determines the amount of powder as gas stream 41.
- Naturally Modifications of these are only to be understood as an example pneumatic arrangement possible.
- on the control valve 46 can be dispensed with when the conveyed air quantity from the source 30 is sufficiently constant.
- a purge air line 59 can be provided if it is not in operation be through which a pressure regulator 60 and a main valve 61 via lines 62 and 63 purge air is conductive in the injector.
- the supply of the gas flow 41 into the injector space 25 can also cross, i.e. at an angle or at a 90 ° angle to the conveying air flow.
