Definitions
- the invention relates to a method and an arrangement for stain-free removal of those adhering to the material to be treated Liquid using compressed air jets.
- the task is with Transport of the goods from one treatment bath to the next carry off as little treatment liquid as possible.
- the Liquid that adheres to the surface of the material to be treated must be removed from the bath after lifting. After the last treatment, the material to be treated must be complete be dry. With certain, usually with decorative covers coated items to be treated, for example sanitary fittings, this drying must also be spot-free.
- the adhering drops then have a disadvantageous effect out if for technical or decorative reasons a completely stain-free good should be produced, because an evaporating Drops of water always leave a visible stain on the surface of the material to be treated.
- DE-AS 24 05 870 describes a dryer for ceramic moldings suggested that the meandering through the dryer room blanks passed with heated air from in Direction of conveyance arranged one behind the other, rotating about its axis or oscillating air distributors can be dried.
- the moisture must not only come from the Surface of the moldings, but especially from the inside be removed. Therefore, the parts must be gentle and be dried slowly. This will include also caused by that the heated air from the air distributors if possible is evenly blown into the dryer room and the In each case, moldings are only intermittently swept over, for more moisture inside the moldings To give an opportunity to get to the surface of the molding. The evaporation of the adhering moisture requires considerable effort Energy expenditure.
- Blow-off devices such as, for. B. jet sticks, which are arranged on the bathrooms. In this case it will Treated items are guided past the nozzle sticks when they are being lifted and blown. In just drying the items to be treated serving devices are motor driven Blowing devices led past the goods there several times.
- EP 0 205 819 A1 describes a method and a device for spot-free drying of items with through Liquid wetted surfaces are described with the subject after immersing in the bath with the treatment liquid directly and quickly into a gaseous treatment medium introduced and simultaneously or subsequently is blown with the gaseous treatment medium to the to blow off treatment liquid wetting the surface.
- the procedure is only for small quantities of too Treating parts suitable, as these in successive Process steps removed from the treatment bath then blow-off nozzles into the one to be dried Part aligned position and the adherent Liquid is removed.
- too Treating parts suitable as these in successive Process steps removed from the treatment bath then blow-off nozzles into the one to be dried Part aligned position and the adherent Liquid is removed.
- the geometry of the material to be treated different constructions of otherwise expensive treatment device required.
- EP 0 486 711 A1 describes a method and a device described for blowing off a liquid from an object, where a variety of high frequency pulsating, abrupt impacts of at least approximately parallel mutually extending pressure jets against the object directed to drive the liquid away.
- the process is also intended for spot-free drying without the use of solvents be suitable.
- the nozzle sticks used for Air blowing is led past the property.
- a microprocessor controls solenoid valves that allow airflow in faster Interrupt sequence. This creates pulsating air blasts, who crush the adhering drops on the material to be dried or destroy.
- the disadvantage of this method is that the air blasts on each side of the product carrier only ever hit the material to be dried from one direction.
- the goods would have to be plate-shaped around all surface areas to be able to achieve.
- For shaped surfaces of the material to be treated reach the parallel rays the nozzle sticks, on the other hand, only a part of those to be treated Surfaces, but not undercuts and recesses, so that stain-free drying in these surface areas not possible. Therefore the drying times in such cases uneconomically long, and air consumption gets too high.
- the one of such Device control used complex and expensive.
- DE 39 20 955 C1 describes a method for aerating a drying material passing through a dryer by an air circulation device with rotatable around its vertical axis and fans arranged one behind the other revealed in which all fans with coordinated rotary position and matching Turn speed.
- the adherent to the material to be treated Liquid is passed through the drying system blown from one side of the parts to the other so that a very sharp jet of air is required to some extent at all to be able to achieve satisfactory drying results.
- the compressed air jets drive the liquid drops on the surface of the material to be treated just in front of you forth, so that the blowing of the drops only a momentary displacement the drop becomes a protected from the air jet
- the location of the material to be treated causes, but not as quickly as possible Remove the drops. It also becomes one of the air jets facing side of the material to be treated only during half of the treatment time captured by the air jets. The air jets are not on during the second half directed this side and therefore effect on this side not even the intended drying.
- US-A-1,711,763 describes an arrangement for drying fruit, where the fruits are on a conveyor belt under an air shower be carried away to adhere to the washed fruit Blowing off liquid residues.
- the air shower consists of a nozzle at the the air jet direction changes transversely to the direction of transport of the fruit becomes.
- the blowing off is done by touching the Fruit surfaces relieved with a curtain attached to the air shower.
- the drying treatment is galvanotechnical coated objects that have sensitive surfaces have, but not possible.
- the present invention is therefore based on the problem to avoid the disadvantages of the prior art and a suitable method and arrangement for spot-free Removal of material adhering to the surface of the material to be treated Finding liquid and a technically simple implementation to enable.
- the inventive method is that of openings compressed air jets in at least one air jet device be constantly directed to a level in which the material to be treated is located, with a relative movement between the air jet device and the material to be treated is provided and that the air jet device in at least one level is moved oscillating.
- At least one the oscillating movements is a torsional vibration movement around its own axis. Come as oscillating movements also linear vibratory movements in the direction of the axis in Consider the torsional vibration movement of the air jet device he follows.
- the openings in the air jet device can also be designed as movable nozzles, where the nozzles perform torsional vibrations about axes, which in turn is at an angle of approximately 90 ° to the axis the air jet are offset by the torsional vibrations or in their direction the linear ones Vibration movements take place.
- the individual vibratory movements can also be run at the same time.
- the air jet device is elongated, for example executed as a tube, so the torsional vibrations about the longitudinal axis of the air jet device and the linear ones Vibrational movements take place in the direction of this axis.
- nozzles preferably perform an oscillatory movement around an axis transverse to the longitudinal axis.
- the openings can on at least one surface line of the air jet device be arranged. As openings can both Drill holes in the air jet device as well as nozzles to be appropriate.

- the Compressed air not only from one direction to the one to be dried Surface directed but from different constantly changing Directions. This ensures that even at strongly shaped material to be treated all surface areas, so also perforations and undercuts, covered and all drops of liquid adhering to it are removed. The complete removal of the drops and not just their current one Displacement is achieved by using high oscillation speeds is worked. The comparatively In addition, sluggish drops cannot evade quickly enough atomize in the air jet sweeping over it.
- the Compressed air jets also during the entire treatment period targeted to the material to be treated and not only during a half turn with a rotation of the air jet device. This will result in a significantly reduced drying time compared to arrangements with rotating air jet devices reached.

Herewith it is achieved that all surface areas of the material to be treated be recorded.
- the relative movement between the air jet device and the material to be treated serves to cover the entire surface of the Paint the items to be treated with the compressed air jets.
- the material to be treated can be in one or more inpatients Air jet devices are moved past. It exists however, the possibility that the air jet devices be moved past the inpatient treatment item. In both cases, the oscillating movements overlap the air jet devices and, if necessary, the nozzles the relative movement between the air jet devices and the material to be treated.
- the air jet devices are on the sides, for example a bath or dryer arranged to simultaneously cover all surfaces to be able to blow off the material to be dried.
- the material to be treated is on goods carriers with known fasteners, such as clips or racks, hung up and carried by trolleys from one treatment bath to the next.
- the length of the Goods carrier is in the range up to a few meters.
- the material to be treated on the goods carrier thus forms two large levels namely a front and a back. From both sides the adhering liquid must be removed.
- the air jet devices can be horizontal, for example Position stationary on at least one side and laterally arranged above the bath level on the treatment tank be to remove liquid adhering to the surfaces when lifting of the items to be treated from the container or when sinking in to blow it off into the container. Especially to recover valuable materials and to avoid carry-over losses this arrangement is advantageous.
- the relative movement is here from the Bad achieved.
- the lifting speed must be chosen so slowly be that the adhering liquid when lifting out once of the material to be treated from the bath from the surfaces is effectively removed.
- a common rotary actuator for their oscillating Movements can be provided by, for example a lifting rod with lugs connected to the nozzles for all nozzles moved up and down together, so that the nozzles in torsional movements be transferred. If the nozzles are one have asymmetrical discharge opening, result from it pressure jets oscillating on a conical surface, whose axes to the longitudinal axis of the air jet device, for example lying across.
- stationary ones can also be used and parallel air jet devices be used. These lead the oscillating movements in at least one direction.
- the relative movement of the goods to the stationary air jet device in this case a hoist that moves it up and down.
- Transport vehicles are also known in electroplating with a cabin for spraying and draining the goods during equipped for the journey.
- the oscillating according to the invention Air jet devices can also be used in such Transport trolley provided and arranged so that the lifted out of the bath or lowered into the bath Treated goods are guided past these air jet devices will, so that adhering liquid while driving past is blown off by means of compressed air jets.
- Advantageous in this case is that at predetermined travel times from one treatment station to the next through an effective one Removal of the liquid from the surfaces an improvement in quality achieved during drying and a time saving will.
- At least one At least one side of the inpatient treatment item an oscillating air jet device moves past.
- the Air jet device can be horizontal relative to the goods carrier, vertically or in another direction, but preferably parallel to the level of the material to be treated.
- air jet devices can also be used on only one Side or on each side of the material to be treated be. If multiple air jets are used, their movements (torsional and linear movements) preferably synchronized with each other.
- the parts of the material to be treated for treatment by a horizontal continuous system emotional in another application, the parts of the material to be treated for treatment by a horizontal continuous system emotional.
- the air jet devices above and below the transport level of the material to be treated be arranged so that the material to be treated in a horizontal Direction moved between the air jet devices becomes.
- the air jet devices are preferred stationary and only lead the oscillating ones Movements through.
- the oscillating movements the air jet devices are carried out in the same way and at the same speeds as a treatment of the good in diving systems.
- the heated compressed air contributes to faster evaporation of the residual moisture at, without using the large thermal energy customary for dryers need to, because the moisture targeted at the good heated locally and with comparatively small amounts of air becomes.
- cleaning is preferably carried out and dried compressed air.
- Already with one low overpressure will give satisfactory drying results reached; for example, with a pressure of 2 bar and running over the surfaces to be dried three times in each direction at a speed of 4 meters each Minutes of spot-free drying.
- the relatively low one Pressure in the compressed air jet has a low air consumption result.
