Description

Technical area

The invention relates to a dryer for drying components, with a fan for generating an air flow flowing around the components.

State of the art

Dryers for drying components are known. In manufacturing processes, especially for the manufacture of electroplating components, components may come into contact with water. Before a final use or completion of the components usually still existing adhesive water is removed. This can be done by evaporation or by mechanical means, for example by flow of the components by means of an air flow or acceleration of the components, for example in the form of shaking off the water. For components with so-called scooping contours, ie shapes in which the water can accumulate, it is known to increase the temperature so far that the water can be removed by evaporation. Drying time may be affected by a choice of mechanical treatment for direct removal of adhesive water and temperature. From the EP 0 650 022 B1 is a method for stain-free removal of adhering to surfaces of items to be treated liquid by means of compressed air jets known. The compressed air jets are constantly directed from openings in at least one air jet direction to a plane in which the material to be treated is provided, wherein a relative movement between the air jet device and the treated material is provided and the air jet device is oscillated in at least one plane and wherein the frequencies of the oscillating motion the air jet device and the pressure of the pressure jets are chosen so high that the liquid is substantially atomized. From the DE 20 2008 014 049 U1 is a trough dryer for drying adhesive water present on rack goods, with an open-topped, trough-like container, with a nozzle arrangement for the continuous injection of air into the interior of the container, with a device for sucking out air from the interior of the container, with a device for Heating the air before blowing it into the interior of the container, known.

Presentation of the invention

The invention has for its object to minimize possible resource-efficient drying of components, in particular without the use of additional compressed air, especially for lower temperatures with relatively short cycle times to achieve a good drying result.

The object is achieved by a dryer for drying components with a fan for generating an air flow flowing around the components through a downstream of the fan and the components upstream air flow control, which is adjustable between a first control setting and a second control setting, wherein the components in the control settings of the air flow have flowed differently dissolved. Depending on the requirements, the components can be flown differently. To shorten the drying time, it is conceivable that the components in the first control setting initially flow so that adhesive water is entrained by the air flow, ie mechanically removed, and to flow around the components for residual drying and / or heating as evenly as possible in the second control setting. This can advantageously be the best possible compromise between mechanical and thermal drying, with energy and resources can be saved. In particular, can be dispensed with an additional compressed air device. The air flow generated by means of the blower itself can be shaped or controlled in different ways.

In a preferred embodiment, it is provided that in the first control setting the air flow for removing water adhering to the components can be accelerated and / or bundled. The air flow can be aligned with the components or at least a selection of components and accelerated thrown on them. As a result, adhesive water can be torn away and thus removed from the components.

In a further preferred embodiment it is provided that in the second control setting the air flow for uniform drying of the components is slowed down and / or distributed. The slowed and evenly distributed air flow can be used after the mechanical removal of the adhesive water for a uniform drying and / or heating of the components. With only one fan can be carried out by the different control settings, the tearing of the adhesive water and the uniform flow around for heating and residual drying of the components. This can shorten a cycle time significantly, in particular at comparatively low temperatures, for example a maximum of 70 ° C., for example for plastic parts. In addition, the adhesive water can also be removed from undercuts and / or scooping contours particularly reliably by the accelerated and / or targeted influx in the first control setting.

In addition, it is conceivable that the dryer has a drying chamber through which the air flow can flow, into which the components for drying can be introduced, the air flow control being arranged upstream of the drying chamber. In the drying chamber, the components can be dried evenly and quickly. Optionally, the air flow can be performed in a circulating air operation, in particular for saving energy for warming up the air flow and / or the components. The air flow control is connected upstream of the drying chamber, so that the air flow is accelerated and / or bundled in accordance with the first control setting and slowed down according to the second control setting and introduced into the drying chamber.

A further embodiment of the dryer provides that the dryer has a switched into the air flow or switchable heating coil for heating the air flow. By means of the heating register, the air flow and the components can be heated to achieve faster evaporation and thus drying.

A further variant of the dryer provides that the air flow control for the first control setting has a first air outlet device for accelerating and / or bundling the air flow and for the second control setting a second air outlet device for slowing down and / or distributing the air flow. The air flow control may control the air flow to be introduced into the drying chamber through the first air outlet device in the first control setting and into the drying chamber through the second air outlet device in the second control setting. Through the two air outlet devices, the air flow can be influenced or formed in the previously described desired manner and introduced into the drying chamber.

A further preferred embodiment of the dryer provides that the air flow control has at least one control flap, is selectively effected by either the first or second control setting. By means of the control flap, the air flow can be easily redirected so that it can be bundled or distributed. In particular, it is conceivable to also set intermediate positions by means of the control flap, so that, for example, both air outlet devices inject part of the total air flow into the drying chamber.

A further preferred embodiment of the dryer is designed such that the first air outlet device is released by the control flap in the first control setting and the second air outlet device is locked, and vice versa in the second control setting. For this purpose, the control flap can be displaced in such a way that it deflects the air flow alternatively either to the first or second air outlet device. By simply moving the control flap this desired effect can be achieved.

Another embodiment of the dryer is configured such that the first air outlet device has at least one nozzle. Through the nozzle, the air flow can be accelerated and / or bundled. As a result, the adhesive water can be removed.

Another embodiment of the dryer is constructed so that the second air outlet device has an air outlet grille and / or a plurality of nozzles. Through the air outlet grille or the plurality of nozzles, the air flow can be fanned out, slowed down and / or evenly distributed. This allows the components to flow around evenly and comparatively slowly.

A further preferred embodiment of the dryer provides that the drying chamber is closable by means of a closure flap which is adjustable between an open position and a closed position, wherein the closure flap and the air flow control are coupled by means of a forced coupling, by means of the air flow control in the opening position of the closure flap the first control setting and in the closed position is set to the second control setting. Through the flap, the drying chamber can be closed. As a result, in particular recirculation mode for drying the components is possible. The flap is coupled by means of the forced coupling with the air flow control. This allows with the shutter open an introduction of the components in the drying chamber, wherein the air flow control is forcibly or automatically in the first control setting. In this control setting the air flow is accelerated and / or bundled. When introducing the components, it is thereby possible to pass them individually to the bundled or accelerated air flow. As a result, the adhering adhesive water can be removed from these already during the introduction of the components in the dryer or in the drying chamber. Subsequently, a recirculation mode for heating and residual drying can be done by evaporation. Closing the flap automatically sets the second control setting using the forced coupling. In this second control setting, the air flow can flow around the now located in the drying chamber components. These can be heated particularly well and evenly and / or dried by evaporation. Additional settings on the dryer are not necessary. It is only a conventional closing of the flap required after the components have been introduced into the drying chamber. Thus, without further adjustment, the mechanical removal of the adhesive water by the accelerated air flow and then the heating and drying by the slowed or uniformly distributed air flow can take place without further ado.

In addition, it is possible that the air flow control has a plurality of juxtaposed air outlets, which are controllable by means of a slide for generating the control settings. By means of the slide so a variety of air outlets can be controlled simultaneously. The air outlets may be matched to the slider so that they cause the acceleration or slowing of the air flow depending on a sliding position of the slider.

Furthermore, it is conceivable for the slide to have a multiplicity of control openings through which the air flow can flow in order to control the air outlets. The control openings can cooperate with the air outlets by means of the slide so that they are selectively released or closed depending on a sliding position of the slide. If a corresponding control port is located above one of the air outlets, the airflow flows through both into the drying chamber. A remaining between two control openings portion of the slide closes in an overlap with one of the air outlets this accordingly.

A further preferred exemplary embodiment of the dryer is configured such that the control openings are arranged at a first pitch and the air outlets at a second pitch differing from the first pitch are spaced apart from one another. Due to the different pitch of the control openings and air outlets, it is possible to produce a so-called moiré effect, so that a position for accelerated ejection of the air flow along an extension of the slide, at which it opens the air outlets can be adjusted. The air outlets can be introduced in particular in a wall of the dryer, in particular a wall of the drying chamber. On an outer side of the slide can be positioned, wherein depending on a relative position of the slider to the outer wall, the air flow at different locations of the wall can be accelerated introduced into the drying chamber.

Another possible embodiment of the dryer is constructed so that the slider is coupled by means of the positive coupling with the closure flap, wherein the slider occupies a plurality of intermediate positions, which causes by means of the different pitches a wandering acceleration and attenuation of the air flow along the mutually arranged air outlets. The slide can each be moved along one direction, that is to say one-dimensionally, or alternatively two-dimensionally relative to the air outlets, in particular the wall of the drying chamber. As a result, and by means of the different pitches, a variable positioning of opened, in particular the air flow accelerating air outlets is possible, the other air outlets are closed. It is also conceivable that due to the different pitch several of the air outlets bundle the air flow. This allows the components to be blown off side by side. This corresponds to the first control setting. To achieve the second control setting, the slider can be kept in motion, for example, so that the air flow circulates in a desired manner and thereby distributed. Alternatively or additionally, it is conceivable to bring the slider in such an intermediate position that at a desired position, a certain proportion of the air outlets are only slightly or partially open, so that thereby the desired distribution of the air flow takes place.

Finally, it is conceivable that two of the air flow controls are provided, which are arranged opposite one another. This allows the components to be dried on both sides. Alternatively or additionally, it is conceivable to thereby dry two rows of components. The components can be introduced by means of a so-called component carrier in the drying chamber. It can therefore be a variety of components. It is possible to align each front of the components in the direction of the air flow controls. As a result, the front pages visible later in use of the components can be dried particularly well and uniformly. In particular, the adhesive water can be removed in advance so that as far as possible no drying residues remain on the front sides of the components.

Further advantages, features and details will become apparent from the following description in which - where appropriate, with reference to the drawings - at least one embodiment is described in detail. Described and / or illustrated features form the subject of the invention, or independently of the claims, either alone or in any meaningful combination, and in particular may additionally be the subject of one or more separate applications.

Before describing the invention in detail, it should be noted that it is not limited to the respective components of the device and the respective method steps, since these components and methods may vary. The terms used herein are intended only to describe particular embodiments and are not intended to be limiting. In addition, if singular or indefinite articles are used in the specification or claims, this also applies to the majority of these elements unless the overall context clearly makes otherwise clear.

1 shows a longitudinal section of a dryer 1 in which at least one component 3 is dryable. The components 3 can at a goods carrier 37 attached and by means of this in a drying chamber 11 of the dryer 1 to be introduced in what 1 by means of a first double arrow 39 is symbolized. On the right half of the 1 is just the goods carrier 37 in the drying chamber 11 brought in.

The dryer 1 has an airflow control 9 auf, which according to the embodiment of the 1 a control flap 19 having. The control flap 19 is by means of a forced coupling 29 with a flap 27 of the dryer 1 positively coupled. The forced coupling 29 has a wave 41 and one with the wave 41 coupled lever 55 on. By means of the wave 41 and the lever 55 can the control flap 19 between a first control setting of the airflow control 9 , in the 1 shown on the right, and a second control setting in 1 shown on the left. This is the control flap 19 at a swivel joint 57 pivoted. The wave 41 is due to a displacement of the flap 27 actuated. The flap 27 is relative to the rest of the dryer 1 displaceable or displaceable, what in 1 by means of a second double arrow 43 is symbolized. According to a shift in the direction of the second double arrow 43 becomes the wave 41 and in succession over the lever 55 the pivoting control flap 19 actuated.

By means of a blower 5 can be inside the dryer 1 an airflow 7 be generated. The airflow 7 is symbolized by a variety of arrows and can be performed with the shutter closed along a Umluftfluidpfades or in recirculation mode. The airflow control 9 or the control flap 19 the airflow control 9 is in the airflow 7 switched, namely the blower 5 downstream and the drying chamber 11 upstream. As right in 1 to recognize is with the flap open 27 a nozzle 21 the blower 5 downstream. The entire air flow 9 So it's through the nozzle 21 in the drying chamber 11 flows into this blown. This allows the airflow 7 be accelerated and bundled. It can be seen that this only a small area of the product carrier 37 and therefore only one or a few of the components 3 from the airflow 7 be dried. Advantageously, thereby the entire amount of energy of the air flow 7 that the blower 5 supplies, on one or at least only a few of the components 3 be concentrated. This may possibly affect the components 3 remaining adhesive water can be safely removed. When introducing the goods carrier 37 in the drying chamber 11 can all the components in succession 3 blown off and thus be released from the adhesive water. Once all the components 3 So the entire product carrier 37 completely within the drying chamber 11 what is in 1 The left side is symbolized, the flap can 27 getting closed. It is by means of forced coupling 29 the airflow control 9 actuated. Specifically, the control flap 19 from the air outlet grille 23 lifted. This is compared to the first tax adjustment, as in 1 shown right, the air outlet grille 23 released, so can from the air flow 7 be flowed through. At the same time the control flap beats 19 from the inside to a fluid path for guiding the air flow 7 in the direction of the nozzle 21 and blocks it with it. The nozzle 21 will be in the in 1 Left shown control setting of the air flow control 9 no longer flowed through. This is the entire air flow 7 through the air outlet grille 23 in the drying chamber 11 blown. This allows the airflow 7 slows down and in particular with a reduced flow resistance within the drying chamber 11 be performed evenly.

As in 1 It can also be seen is the blower 5 a heating register 13 downstream. The heating register 13 is between the fan 5 and the airflow control 9 connected. This allows the airflow 7 for uniform heating and drying of the components 3 be heated by evaporation. This is preferably done in the closed state of the dryer 1 like this on the left side of the 1 is symbolized.

The airflow control 9 points in the form of the nozzle 21 a first air outlet device 15 and in the form of the air outlet grille 23 a second air outlet device 17 on. Depending on the control settings of the airflow control 9 will either the entire airflow 7 through the first air outlet device 15 or the second air outlet device 17 guided. Accordingly, the functions can blow off the components 3 or uniform recirculation can be set. The nozzle 21 can be formed as a slot and / or nozzle row. This is advantageously dependent by means of the forced coupling 29 from the opening position, as in 1 shown right, or the closing position, as in 1 shown on the left, the flap 27 , The flap 27 is designed as a double flap, so has a left flap and a right flap, which are moved towards each other and thus the dryer 1 can close.

2 shows a further embodiment of the in 1 shown dryer. In the following, only the differences are described in detail and according to the description of the 1 directed.

In contrast to the representation in the 1 points the dryer 1 according to 2 instead of the air outlet grille 23 a variety 25 for example, the nozzles 21 on. The nozzles 21 may be part of a nozzle wall that defines the fluid path to transition the airflow 7 from the drying chamber 11 separates. According to the control settings of the airflow control 9 can the control flap 19 be pivoted or shifted so that either either the nozzle 21 the first air outlet device 15 or the multitude 25 the nozzles 21 the second air outlet device 17 the airflow control 9 released and thus from the air flow 7 are flowed through. According to an alternative, to set the second control setting, all nozzles 21 be streamed. This can be the flap 27 in an in 2 not shown intermediate position can be brought.

3 shows a further embodiment of the in the 1 and 2 shown dryer. Accordingly, the description of the 1 and 2 directed. In the following, only the differences are discussed.

In contrast to the representation of the 1 and 2 points the dryer 1 according to 3 an airflow control 9 with a slider 33 on. The slider 33 becomes upper a crankshaft 45 relative to a variety 25 of nozzles 21 shifting what's in 3 by means of a third double arrow 47 is symbolized. The slider 33 has control openings 35 on, by the airflow 7 can be flowed through. The control openings 35 can so over air outlets 31 that the respective nozzles 21 upstream, be positioned that they are released. Should the tax opening 35 between the air outlets 31 can be positioned, these by means of the remaining slider 33 be locked.

The control openings 35 are arranged relative to each other. Preferably, these are arranged regularly to one another, in particular by means of a first division. A division can be understood to be a distance of the individual control openings relative to one another and / or relative to a size of the individual control openings.

Corresponding are the air outlets 31 that by means of the slider 33 optionally lockable or openable, with a second pitch arranged relative to each other, in particular in the drying chamber 11 demarcated wall introduced. The second division of the air outlets 31 differs from the first division of the tax opening 35 of the slider 33 , This allows relative displacement of the slider 33 to the air outlets 31 a so-called Moiré effect are generated, so that depends on a position of the slider 33 the individual air outlets 31 successively stronger or weaker are controllable. As in 3 To detect, thereby accelerations and delimitations of the air flow 7 be generated in a corresponding pattern. As in 3 On the left side, approximately in the middle, there is a particularly strong flow of the components 3 , In particular for removing the adhesive water, and spaced from a comparatively weak flow possible. According to another position of the slider 33 , in the 3 can be shown, two comparatively bundled parts of the air flow 7 and a slightly weaker flow of the components 3 be generated. This can be used to advantage, the components 3 to use one after the other to blow off the adhesive water. In the first control setting, which is used to blow off the adhesive water, so can the slider 33 be adjusted so that as hard and aligned bundled outflow of the air flow 7 takes place, as in 3 is shown on the left. For the second control setting, the slider 33 be positioned so that as many as possible 25 the nozzles 21 are open and so evenly distributing and slowing down the air flow 7 he follows. Further, under the tax settings be understood that the slider 33 is moved in a particular movement pattern, in particular oscillating at different speeds, the optional accelerating the air flow 7 at desired locations or components 3 and optionally alternatively as evenly as possible distributing the air flow 7 causes.

4 shows a side view of the in the 1 and 2 shown dryer 1 , 4 shows an example of an external part of the forced coupling 29 , In the 4 shown forced coupling 29 can by a different arrangement also on the 3 be transmitted. The outside of 4 visible forced coupling 29 has an outside lever 49 on, the hinged to the flap 27 is connected. In addition, the outside lever 49 in the middle of the 1 and 2 visible wave 41 pivoted. On the flap 27 opposite side is the outside lever 29 hinged to an actuating cylinder 51 tethered. The actuating cylinder 51 in turn is hinged to a housing 53 of the dryer 1 tethered. Depending on the position of the adjusting cylinder 51 can the outside lever 49 be pivoted. In 4 left is the closed position of the flap 27 in which the actuating cylinder 51 is extended, and right, the open position of the flap 27 in which the actuating cylinder 51 retracted, shown. By means of the outer lever 49 thus becomes the shutter at the same time 27 opened and closed and via the non-rotatable connection of the outer lever 49 on the shaft 41 the control flap 19 actuated. The control flap 19 will, as in the 1 and 2 shown over the lever 55 , the inside also rotatably with the shaft 41 is coupled, actuated or pivoted.

The in the 1 to 4 shown embodiments of the dryer 1 come out without an additional application of compressed air. The airflow 7 is exclusively by means of the blower 5 generated. Alternatively, however, it is also conceivable, in addition to the advantageous air flow control 9 a blowing off of the components 3 to provide by means of additional compressed air. Preferably, however, is waived, since an additional compressed air network that provides higher pressures, for example, 5-7 bar, can be dispensed with, or this, if it is present, not so strong by the drying of the components 3 must be used. As a result, maintenance and operating costs can be saved. Due to the airflow control 9 can the airflow 7 be accelerated so that the blower 5 is enough for the components 3 safe to blow off, so to free from the adhesive water. For the later circulating air operation, in which lower flow velocities are sufficient, as described above, the air flow 7 slowed down again or in the drying chamber 11 be guided. While accelerating the airflow 7 can the adhesion of water to the components 3 be overcome, so that this can be removed from them. Overall, the drying process can be accelerated and the energy input can be reduced. Otherwise usual components of the blower 5 can also be used to blow off the adhesive water. The acceleration of the airflow 7 can take place with comparatively low pressures, for example of about 900 Pa, in particular between 700 and 1200 Pa. These pressures can be provided by means of the blower. Additional fan units and / or the use of external compressed air is not required, but may also be provided and / or used in another embodiment, for example for special drying applications. The otherwise conducted in a recirculation mode airflow 7 can by means of the first control setting, for example by using point jet nozzles, for example, the in 1 shown nozzle 21 , specifically for blowing off the components 3 be used. Preferably, the first air outlet device is located 15 , in particular the nozzle 21 , in the region or adjacent to one of the closure flap 27 closable opening of the drying chamber 11 , in alignment with 1 seen, so above. This can be a sweep of the entire product carrier 37 by means of the accelerated air flow 7 take place so that one after the other when introducing the components 3 these can all be blown off. This allows a locally high flow velocity of the air flow 7 be generated that a sufficient blow-off, in particular for overcoming the adhesive forces of the water to the components 3 and separating the adhering water from the components 3 and / or from the product carrier 37 , which accelerates the drying process and / or reduces the energy input, depending on which aspect outweighs.

For the blow-off process other boundary conditions apply than for the actual drying process. This can be done in the first control setting either for the first air outlet device 15 a high air speed and a high throw for blowing off the components 3 and in the second control setting, for example via the air outlet grille 23 and / or the multitude 25 on nozzles 21 a comparatively high volume flow with comparatively low flow resistance for the drying process can be generated.

The first air outlet device 15 and the second air outlet device 17 are preferably not opened at the same time, so that they are alternately closed or opened according to the control settings.

This in 1 shown air outlet grille 23 can, as in 2 shown, if necessary by the multiplicity 25 further nozzles 21 be replaced. Particularly advantageous is the forced coupling 29 the flap 27 with the airflow control 9 , The blow-off function of the components 3 can with the flap open 27 take place, the flap 27 horizontally to open and close is displaced. By means of the forced coupling is during insertion, so open shutter 27 , first the blowing off of the components 3 causes. Once the flap 27 is closed, is by means of the forced coupling 29 also the airflow 7 via the second air outlet device 17 controlled so that the comparatively large volume flow for uniform flow around the components 3 occurs. The forced coupling 29 can by means of the outer lever 49 , the crankshaft 45 , the lever 55 and finally the flap 27 respectively. The drive takes place by means of in 4 shown actuating cylinder 51 , Alternatively, the in 3 shown crankshaft 45 be provided. According to another alternative, the crankshaft 45 and / or the wave 41 be driven directly, for example by means of an electric machine.

As in 3 To recognize, can have different rows of nozzles 21 by means of the slider 33 be controlled in succession. Depending on the design of the slider 33 , so the tax opening 35 compared to the air outlets 31 , these can either be like in 3 shown by the different division, ie the moiré effect or by individual driving, for example by a series of control openings 31 , one after the other over all air outlets 31 is pushed, controlled. According to another alternative, the slider 33 be designed so that successively different rows of the air outlets are released, so successively from the flap 27 starting in the direction of the blower 5 the nozzles 21 be released in rows, so that the entire product carrier 27 , in alignment with 3 seen from top to bottom by means of the accelerated air flow 7 can be flowed. Time-displaced, preferably horizontally stacked rows of nozzles 21 may preferably open or close at different times, wherein a blow is made possible regardless of Wareneintauch- or Warenausauchvorgang to use an entire cycle time for the blow-off. The blow-off process is such that, preferably, of edge regions, in particular above, in particular in the region of the closure flap 27 starting, the flap 27 and / or the slider 33 a row of nozzles 21 opens and after a certain residence downstream of this preferred down subsequent rows of nozzles 21 be opened after the closing operation, wherein successively the superposed rows of nozzles are temporarily released and closed again, until a lowermost row of nozzles was opened. This allows all the components 3 be blown off during the cycle time of a drying process. The pitches can be so matched to each other that no matter how this is set over the entire length of the slider, only a maximum for accelerated blowing out of the air flow occurs.
