Description
DEVICE FOR PAINTING BY DEW POWERS OF WORK
DESCRIPTION OF THE INVENTION
The invention relates to a device for spraying workpieces with paint, which has at least two coating cabins, arranged along a transportation path for the workpieces, and a
spray device. Such a spray coating device is particularly suitable for coating electrostatic powder. The principle of powder coating
electrostatic is mainly used to coat metal sheets and parts with lacquer
"" Finished, since it is particularly economically and environmentally innocuous, in addition, quantities of high performance material can be achieved.
lacquered, with powder coating systems. In conventional powder coating systems, however, as in laundering systems that work according to
other paint coating methods, arise REF: 24115 problems when changing the color. In particular, in order to achieve a homogeneous and uniform coating together with a high performance of material to be bonded, a stream of concentrated paint powder is directed onto the workpiece to be laced, but only some of the paint powder is adheres to the work piece, while remaining paint dust settles in the system. The coating systems known therefore have a suction extraction device in order to return the excess paint powder to the paint powder circuit. However, the paint powder particles always remain adhering particularly to the walls of the coating booth and, in the case of a color change, cause color mixing and consequently an impurity. In order to avoid this, the coating booth has to be cleaned as long as the color is changed. This therefore always leads to costly immobilization times in the coating system. In addition, particularly an electrostatic powder coating system, a relatively large amount of time is needed for cleaning during a color change, since the particles of the paint powder, by virtue of its electrical charge, are frequently
adhere firmly to the coating booths. In order to allow a rapid color change in powder coating systems, powder coating systems possessing a plurality of coating booths for
different colors, so that a cabin can always be cleaned alternately for color change, are already in use. CH 663,008, A5 describes such a powder coating system, which has the characteristics of the
precharacterization of claim 1. In this known powder coating system, it is
"/ _ Accommodate two coating cabins with one another that are supplied by means of a switch via a common rail or transportation route. Do not
However, this system is very expensive, since two complete coating booths, each provided with a spray device, are necessary. The object of the invention is, therefore, to provide a cost-effective device for the spray coating of workpieces which allows a rapid change of color. In a generic device for spraying workpieces, this objective is achieved by means of the measures specified in the characterization clause of claim 1. Accordingly, at least two coating cabins accommodated along the guide of transportation for the work pieces are designed in two parts, the parts of the cabin being separable from one another, so that the spraying device can be transferred between the coating booths. In the spray device according to the present invention, the immobilization times during the color change can be substantially reduced, since, by designing two parts of the coating booths, the spray device can be transferred simply and quickly between the coating booths having the different paintings In this case, the cleaning of the spray device consisting of a spray gun arrangement, can be carried out easily by blowing it to clear it by means of compressed air. The use of only one spray device for both coating booths substantially reduces production costs compared to a system that has two booths
coating fully equipped. According to a preferred embodiment of the invention, the parts of the car can be separated one from the other transversely with respect to the transportation guide for the
pieces of work. The coating booth is thus accessible in a simple manner and can be cleaned quickly and effectively. According to a further embodiment of the invention, the coating booths are
designed cylindrically. This leads to an additional substantial reduction in the times of
< - / cleaning during the change of color, since the corners and edges, from which the paint deposits can be removed only with
great difficulty, are avoided as a result of the cylindrical design of the internal walls of the cabin. This advantageous design of the internal walls of the cabin can also be adopted, independently of the design of double cabins of
according to the invention, in conventional spray coating devices for the purpose of improving the ease of cleaning. Furthermore, according to an advantageous embodiment, the spraying device is accommodated
movably on a translation rail located between the coating booths, thus providing an additional cleaning device for the spray device on the guide of the translation rail. Through this
The cleaning device can easily and quickly remove possible deposits of paint on the spray device which, particularly in the case of an extreme color change, for example from black to white, can
lead to impurities on the material to be laced. ,., According to a further advantageous embodiment of the invention, a suction extraction device is centrally embedded
on the floor of the coating booth, while the floor of the booth can additionally be further elaborated in the form of a funnel and be provided with a ventilated fluid plate. The arrangement of the extraction device by suction
on the floor of the cabin below the workpiece makes it possible, on the one hand to achieve the improvement in the efficiency of application, since the paint powder discharged by the spray device is retained for longer in the vicinity
of the material to be laced. In addition, as a consequence of this arrangement of the suction extraction device, a coating booth with an extremely small stationary surface can be produced. In addition, the
The funnel-shaped design of the cab floor and the mounting of a ventilated fluid layer allow the extraction by effective suction of excess paint powder during the coating operation. Therefore, they are prevented
The paint dust deposits on the walls of the cab greatly simplify the cleaning of the coating booths significantly. ** In addition, an interior cleaning system
frequently used in conventional systems, and designed to remove paint powder from the inner wall of the coating booths, can therefore also be provided. A traction device by
The described suction can also be advantageously employed, independently of the design of double cabins according to the invention, in the spray coating systems which are already known. According to a further advantageous embodiment of the invention, the spray device consists of at least two rows of spray guns which are arranged vertically one above the other, and which are located opposite each other in the booths of coating on both sides of the transportation guide for the work pieces. As a result of this design of the spray device, a very uniform and stable cloud of paint powder can be formed in the region of the material to be laced, leading in this way to a remarkable improvement in the efficiency of application. Furthermore, a very uniform application of the paint powder on the material to be bonded is also guaranteed in the regions of the problem areas, such as, for example, corners and edges. In addition, the arrangement in vertically placed rows, located opposite each other, ensures an appreciable decrease in operating costs, since the paint powder losses can be substantially reduced taking into account the formation of a dust cloud. Also, fewer spray guns are required compared to conventional spray devices, thus reducing purchase costs and maintenance costs. This spray device can also be used advantageously in conventional coating systems, independently of the spray coating device according to the invention having a double cabin. According to a further advantageous embodiment of the aforementioned spray device, two rows of spray guns arranged vertically one above the other, are mounted in the coating booth on both sides of the transport guide, the spacing between the rows of spray guns located opposite one another. The advantage of this design of the spray device is that the problematic sites of the material to be laced can be covered by the rows of spray guns lying nearby, since the surface coverage can be carried out by means of the rows more widely spaced, which, in addition, can have special nozzles of the spray guns. In addition, the spray device can also be coupled to a lifting device, in order to achieve with this the optimum distribution of the thickness of the layer, particularly on smooth surfaces of the material to be bonded. An exemplary preferred embodiment of the invention is described below with reference to the drawings. In these:
Figure 1 shows a top view of the coating device according to the invention, and
Figure 2 shows a view of the coating booth of the coating device according to the invention, along the sectional line I-I in figure 1.
The spray coating device according to the invention, shown in Figure 1, has two coating cabins 1 and 2 arranged along a transportation guide 5. Each coating cabin consists of two substantially symmetrical cabin halves, which are arranged on both sides of the transportation guide 5. The side walls of the coating booths are designed as cylindrical surfaces, the coating booths have an essentially circular base in the closed state. The cylindrical design of the internal walls of the coating booth makes it easier to remove deposits of paint dust, since corners and edges where access is difficult are avoided. The two parts of the coating booths are displaceable along two translational rails 3 which are located under the coating booth, and which are preferably arranged perpendicularly to the transportation guide. In the representation shown in Figure 1, the two parts of the coating booth 2 are withdrawn from one another along these translational rails 3, transversely with respect to the transportation guide, so that the cleaning of these cabins for a color change, can be carried out. In addition, located between the coating booths 1 and 2, there is a translating rail 7, on which a spray device 8, movably arranged in the coating booth 1, which is in operation, is movably accommodated. Each coating booth additionally has a paint powder storage container 9 and a paint powder measuring device 10 connected to the latter. The measuring devices 10 in each case have connections, to which the powder supply 11 connected to the spray device 8 can be releasably connected, as shown in the coating booth 1 which is in operation. In addition, a suction extraction device 12, which is embedded in the floor of the cabinet and which is connected to a dust recovery system 13, is provided in each coating booth. By means of this device 13 working, for example, on the principle of the cyclone, the paint powder extracted by suction from the coating booth can be filtered from the spent air of the coating booth. In addition, the powder device 13 is connected in each case to the powder storage container 9, in order to return the recovered paint powder to the paint powder circuit. The dust recovery devices 13, coupled to the coating booths 1 and 2, can in each case be releasably coupled to a final filter system 14 which is located between the coating booths, as shown in the coating booth. 1 which is in operation. The final filter system 14 serves to clean the spent air extracted by suction from the coating booth. To clean the spray device 8, a cleaning device 15 is additionally provided between the coating booths 1 and 2, by means of which cleaning device the paint deposits can be automatically eliminated on the cleaning device 8, for example by granulation medium. In addition, the spray coating device has a control device 17 for fully automatic regulation of the entire coating operation, including color change. This control device is connected to a fire suppression system 16, in order to extinguish the fires in the paint powder. Figure 2 shows a cross section through the coating booth 1, which is in operation. An orifice 25 of the suction extraction device 12 is centrally embedded in the floor of the cabinet directly below the workpiece to be laced. The floor of the cabin is made funnel-shaped with respect to this suction extraction hole 25, in order to allow the extraction by simple suction of excess powder precipitated in the coating booth. In addition, the floor of the cabin is provided with a fluid plate 24 operated by means of compressed air; the compressed air on the fluid plate generates a stream of floating paint powder particles which moves in the direction of the hole 25 of the suction traction device 12. The above-described design of the traction device by suction of the powder paint, allows the extraction by suction, effective, of excess paint powder while avoiding to a large extent the deposits on the walls of the coating booth. The spray device 8 for the paint powder has four rows of vertically guided spray guns 21, which are designed, in particular, as tribo-guns, two rows being always located opposite one another in each case, in order to generating a stable and homogeneous cloud of paint powder on the workpiece 18. The spacing between the first two rows of spray guns 21 is selected smaller than the spacing between the second two rows. The most widely spaced spray guns 21 have nozzles that generate spray jets with high output divergence, and serve mainly to cover the parts of large-area workpieces. In contrast, the first of the spray guns that lie closest together ensures, with its lower output divergence from the spray jet, in particular a reliable spraying of the troublesome sites on the workpiece, for example the channels and inclinations, or the places where access is difficult in the deep work pieces. The rows of spray guns are
arranged movably on a platform 23 in each case by means of a clamping device
22 of the spray gun. In addition, the platforms
23 are connected to a lifting device 20 which ensures a movement of
oscillating elevation of the platforms, and consequently of the rows of the spray guns. The oscillating movement of the spray device 8 ensures a uniform distribution of the thickness of the paint powder layer on the
workpiece 18. The supply of paint powder to the
• "Rust pistols 21", takes place vertically from above by means of supply 11 of the paint powder. This design of the powder or paint supply prevents a column of paint powder from occurring in the spray guns 21 during the start of the coating booth, whose column of paint powder could be established by virtue of the dead weight of the particles of powder in the case of a supply of paint powder from below. Arranged along the transportation path 5 are aerial trucks 6 which have a suspension 19 for holding the work piece 18 to be laced. As soon as an aerial trolley 6 has a workpiece to be laced, it moves towards the coating booth which is in operation, the spraying device 8 begins the spraying operation. The paint powder particles fed from the paint powder storage container 9 via the powder measuring device 10 and the powder supply 11 to the spray device 8, are electrically charged in the spray guns 21, and are ejected by means of the nozzles on the spray guns. As a result of the arrangement of the vertical rows of spray guns on both sides of the transportation guide, a stationary cloud of paint powder is generated on the work piece, thereby ensuring high application efficiency. The use of a plurality of rows of spray guns differently spaced, with different groups of nozzles, also makes it possible to ensure a uniform coating on the parts of the large area of the workpieces and of the corners and edges thereof. According to an advantageous execution of the spraying operation, first a large area coverage of the workpiece to be laced is carried out, by means of the rows of spray guns with wide output divergences, and subsequently it carries out a coverage of the problem areas by means of the rows of pistols of roclo that lie more closely, and that have spray jets more sharply directed. In the exemplary mode shown in
Figure 2, the rows of spray guns are movable along the platforms 23 by means of the clamping devices 22 of the spray guns, so that even the wide work pieces can be completely covered. In this case, the work piece is moved beyond the rows of the spray guns, for example, at a conveyor speed of 6 m / min. However, it is also possible to additionally provide a tracking device for the spray gun, which runs synchronously with the aerial truck. The bonding yields of 800 m2 / hr can be achieved by means of the coating device according to the invention. Excess paint dust that does not adhere to the workpiece is suctioned in a downward direction by means of suction extraction device 12, accommodated below the workpiece. The fluid plate 24 located on the floor of the cabin and operated by compressed air, generates a stream of floating particles of paint powder in the direction of the orifice 25 of the suction extraction device 12, by means of which the paint powder , together with the spent air, is guided to the dust recovery device 13. In the dust recovery device 13, the paint powder is filtered and returned to the paint powder circuit. Suction extraction capacities of up to 8,000 m 3 / hr can be produced by means of the suction traction device 12 shown in the exemplary embodiment.
r ^ - When a color change is provided from a first color to a second color in the spray-coating device, the supply of paint powder to the device
of spray 8 is interrupted. The powder supply 11 and the spray device 8 are then cleared by blowing the paint tanks of the first color, by means of pulsed compressed air. Subsequently, the powder supply 11 is decoupled from the powder measurement device 10 for the first color, and the two parts of the coating device are separated from one another. The spray device 10 is then moved along the translation rail to the coating booth loaded with the second color. If an extreme color change is involved, for example from dark brown to white, an additional cleaning step is carried out for the spray device 8, in the cleaning device 15 accommodated on the translational rail. After the spray device 8 has been moved into the coating booth for the second color, the latter color is closed and the powder supply 11 is coupled to the powder measurement device 10 for the second color. The color powder operation can be controlled automatically by means of the control device 17, in the same manner as the spraying operation.
It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it refers.
Having described the invention as above, property is claimed as contained in the following:
