Definitions
- the invention relates to a washing system for cleaning workpieces according to the preamble of claim 1.
- washing systems are generally known and in Available commercially. They are used to clean workpieces, For example, stamped or turned parts that follow degreasing the molding process and / or by Chips or other residues must be exempted.
- the workpieces are taken up in a washing drum and remain there during the cleaning process.
- the liquid detergent is sprayed through nozzles fed and acted upon the recorded in the drum Workpieces.
- the cleaning agent is in the Usually fed under pressure so that a safe application from at the dirt adhering to the workpieces is ensured.
- washing systems differ from the cleaning result have proven, they have some disadvantages. Because the workpieces for example, as bulk goods in the drum and treated in batches, there is a risk of Damage from constant beating. At least the surfaces suffer in terms of their visual appearance, which for a variety of applications of is of great importance. It also leaves in some cases the effectiveness of the cleaning process leaves something to be desired especially for parts of complicated geometry with undercuts or depressions that are sprayed by the Detergents are not always reliably detected. So individual workpieces are often replaced by additional ones Workpieces covered, which is also reflected by a corresponding Rotational movement of the drum and long-lasting action of detergents cannot always be reliably prevented.
- the present invention was therefore based on the object to further develop a washing system of the type mentioned at the outset, so that the disadvantages described no longer occur.
- it should be gentle and effective at the same time Workpieces can be cleaned.
- the invention is based on the idea of separating the workpieces to treat and design the cleaning process in one go. This makes it possible to optimize each individual workpiece to get rid of liquid and / or solid residues, since the Detergent jet completely on the passing Workpiece can be aligned. That with this system Realized throughput processes also allow high throughput on workpieces per unit of time, so that with the help of Washing system according to the invention cost advantages over the previously known washing systems with batch cleaning let achieve.
- the car wash is involved in the concrete implementation of this idea a feed device with which the workpieces are separated be fed to the drum.
- the drum is from a screw conveyor axially penetrates the feed Individual workpieces through the area of the drum transported and passed the nozzles of the spraying device.
- Screw conveyors made up of a large number of angular segments which is circumferential and axial around a central axis are progressively arranged. In this way one can any screw geometry with the help of simply shaped Build up sections.
- transitions allow a largely angle-independent Arrangement of the drum starting from a horizontal Position up to an almost vertical arrangement because the workpieces from the stages or paragraphs thus formed be taken along and back within the conveyor line are hindered. Also change the work pieces during during transport their angular position by rolling over individual stages so that the spray jet the workpiece from only the sides are grasped and therefore also recesses or undercuts reliably achieved.
- the screw conveyor is particularly easy to use by means of angle segments build up that are designed as flat plates. These panels can be made particularly easily from larger panels are cut and do not require any additional shaping.
- the ideal line of the screw geometry is thus flat Levels approximated, whereby the set the desired transitions.
- the structure to be manufactured is also the formation of the drum Shape of a regular polygon, especially a hexagon, consider.
- the drum is preferred by axially continuous support rods formed that accommodate the angular segments.
- the Support rods have axially continuous holding grooves, so that the Angle segments simply one after the other to form the screw conveyor be inserted.
- Perforated walls attached between two adjacent supporting bars. These can also be inserted in holding grooves be, so that the drum as a whole without problems Put together and fix together.
- the support rods can each be supported by bearing rings be fixed, the drum overall a high mechanical Give stability.
- the arrangement of the drum is preferably inclined, for example at an angle between 30 ° and 60 ° the horizontal.
- the drum in its lower Area immersed in a liquid bath with detergent be so that the supplied workpieces first in Cleaning bath completely flooded and in the further course by transporting the screw conveyor out of the bath pass through an area of the drum in which the cleaning agent is sprayed out under pressure under nozzles.
- the washing system is particularly compact, if the spray device is designed as a nozzle tube and concentric arranged to the axis of rotation within the drum is. It also ensures that the workpieces are guided past the nozzles at a short distance be so that the cleaning effect is optimal.
- the nozzles are preferably only in an axial section attached to the nozzle tube, namely the one who is located above the liquid bath. It becomes detergent only sprayed in the area that is above the liquid level.
- a friction roller drive is particularly useful for driving the drum proven, preferably on one of the two bearing rings acts immediately.
- This type of drive has further advantages in connection with the preferred possibility the drum interchangeable, and especially on the To design friction roller drive to be placed loosely. So that can individual drums can be easily replaced, for example an optimal adaptation to different workpieces to enable. So it is possible within a very short time the changeover to workpiece lots with different workpieces Make geometry. The set-up times of the car wash can be significantly reduced.
- the friction roller drive is preferably designed so that it is a rapid pre-setting of the desired drum speed allows, with a speed range between 7 and 30 revolutions per minute has proven to be optimal.
- the drum and the screw conveyor are preferably made of one abrasion-resistant plastic, so that the workpieces at No damage.
- the hardness of Plastic is dependent on the material of the workpieces chosen so that damage to the surface even when Knocking over into another position is absolutely avoided.
- Two or more such drums in series are preferred arranged and via devices for transferring the workpieces connected with each other. It can be repeated and successive treatment by flooding in the liquid bath and then spraying with cleaning agent will be realized.
- the transfer from one drum to the next can be special can be easily realized via part slides so that none are active driven transfer devices are required.
- the washing system of all components is preferred receiving supporting frame held.
- the car wash provides thus an independent module that is particularly simple in parts production can be integrated. If applicable, the Carrier frame designed to be movable, so that flexible use is possible in different and changing places.
- drums 10 At the heart of the washing system are drums 10, the screw conveyors 20 have. These are used in the below workpieces described in more detail individually to transport and permanently knock over during the run.
- the drums 10 are inclined obliquely to the horizontal and stored rising in the direction of conveyance. You dive with Your lower ends in a liquid bath, not shown one that in each assigned liquid container 50 is introduced.
- the drums 10 are driven in rotation, the speed preselectable between 7 and 30 revolutions per minute is.
- the drive takes place via a drive motor 60, one central and 10 common for all drums
- Drive shaft 62 drives. Be from the drive shaft 62 64 friction rollers 66 set in rotation via drive chains which the drums 10 are placed directly on.
- Nozzle tubes 18 are attached in the center of rotation of the drums 10, through the cleaning agents with a pressure of approx. 3 to 20 is pressed out bar.
- the nozzles are aligned in such a way that a fanned spray onto the one below Create the area of the screw conveyor.
- the nozzles are here only provided in the axial section of the nozzle tube 18, which is outside the liquid bath. This is usually an axial section that is approximately 2/3 of the represents the entire axial extent of the nozzle tube 18.
- the cleaning liquid is not in via feed pumps 52 in detailed manner from the liquid bath supplied, level sensors 54 monitor the level. Furthermore, heating elements 56 are present, each over assigned temperature controls the desired temperature adjust and hold.
- the separate assignment of the liquid container 50 to the respective drums 10 allow different cleaning media to provide and condition, for example rinsing with softened water to provide.
- the workpieces to be cleaned are fed via a feed device fed in the form of a conveyor belt 30 and first handed over to a first part slide 32. From there slide one after the other and continue isolated as a result of the Gravity into the liquid bath and get into the entry area the first drum 10.
- the screw conveyor 20 transports the workpieces axially through the drum 10 above, taking it out of the liquid bath first transported and guided along below the nozzle tube 18 become.
- the special shape of the screw conveyor 20 ensures in the manner described in more detail below that the workpieces are permanently knocked over and thus theirs Change relative position with respect to the nozzle tube 18. So is ensured that the sprayed detergent all Areas of the respective workpiece are recorded.
- the last part slide 32 passes the workpieces on Drying belt 40, which runs as a circumferential wire belt is. Air is blown onto the workpieces via a blower 42, so that they dry completely. To optimize the Hot air is usually blown out during the drying process.
- the Air temperature can be set up to 700 ° C to speed up the drying process. The temperature depends essentially on the material of the drying parts.
- the cleaned and dried workpieces can at the end of the Drying belt 40 to another, not shown here Hand over the conveyor belt or remove it in any other way become.
- a control cabinet 80 contains all the means of control and regulation for the to be able to preselect specific process parameters.
- a housing 74 encloses the liquid container 50 and the Area of the drums 10, with hinged protective hoods 76 Allow access to the drums 10. During the Operation is through observation window 78 given.
- the drum 10 has a hexagonal in vertical axial section Basic shape, the edges being formed by support rods 12 are. Take the support rods 12 (not shown here) Angle segments 22 that progressively and axially are arranged. This creates a helical screw, the as a screw conveyor 20 for the transport of the workpieces worries. Between each two adjacent support rods 12 are arranged flat perforated walls, not shown here, which on the one hand prevent the workpieces from falling out, on the other hand, adequate fluid exchange allow to the inside of the drum 10.
- the angle segments 22 are arranged such that each 22 step-shaped between two adjacent angle segments Transitional areas 24 arise. These ensure that the Workpieces due to the rotation of the drum 10 first in Transitional area 24 was added and subsequently overturned become. This leads to the desired permanent change of position of the workpieces so that they can be used from all sides Cleaning agents are applied.
- the screw conveyor is thus 20 firmly connected to the drum 10. This makes possible the drive of the screw conveyor 20 via the outside of the Drum 10 attacking friction rollers 66.
- Rotating screw conveyor has the shown Conception the advantage of a particularly simple structure.
