Definitions

  • the invention relates to a cabin for coating workpieces with powder.
  • the powder is sprayed in a powder coating booth using one or more powder spray guns on the workpiece.
  • the powder can be electrostatically charged.
  • care must be taken to ensure that the powder in the cabin does not exceed a certain concentration, otherwise there is a danger of explosion. For this reason, the air in the cabin is continuously sucked together with the non-adhering to the workpiece powder, the so-called overspray. In addition, this creates a negative pressure in the cabin, which ensures that no powder escapes from the cabin.
  • a powder spray coating booth in which the cabin floor consists of several flaps.
  • the flaps are arranged parallel to each other. When the flaps are in a horizontal position, a narrow slit is created between the flaps, through which excess powder is sucked into a suction channel located below the flaps.
  • the flaps can be rotated in a vertical position, so that the suction channel is accessible from above.
  • this solution has the disadvantage that the operator can not enter the cabin floor formed by the flaps. This makes it more difficult to manually clean the cabin interior.
  • the cabin has a walk-in floor, wherein between the side walls of the cabin and the floor in each case an inclined wall is arranged, which together with the side wall and the bottom forms a suction channel in the lower corner of the cabin.
  • the two sloping walls each have a suction gap over which excess powder deposited on the floor can be sucked into the suction channel.
  • the disadvantage is that the cabin is expensive to produce.
  • Another disadvantage is that not only one, but two suction ducts are required, which are also very long in an elongated cabin. This can lead to a high pressure loss in the suction channels and thus to a low energy efficiency.
  • the suction pipe is complex. Under certain circumstances, even a discharge conveyor for the removal of the excess powder is required.
  • a powder coating cabinet in which a suction channel is arranged below a walk-in floor provided with suction slots. Between the bottom and the side walls of the cabin, an inclined wall is arranged in each case, from which the excess powder deposited there is blown downwards toward the bottom by means of blowing nozzles which are arranged in the side wall.
  • This design of the lower portion of the cabin is complex to manufacture and has the additional disadvantage that the powder, which is already subject to gravity, is additionally accelerated down to the ground by the blowing air and the suction. This can cause the workpiece to be coated with more powder in the lower area than in the upper area.
  • An object of the invention is to provide a booth for coating workpieces with powder, in which the excess powder is sucked out of the booth via a suction duct and in which the suction duct is designed such that the cover of the suction duct can be automatically cleaned.
  • the amount of air required for cleaning the cabin floor is minimized.
  • the arrangement of the suction line is particularly simple.
  • the number of bends in the suction line is low and the entire length of the suction line is short. The pressure loss is thus reduced.
  • the cab according to the invention also comes with a small installation space.
  • the overall height of the cabin becomes lower without sacrificing the interior height of the cabin.
  • Another advantage is that with the erfindunqsqefflessen cabin over the entire height of the workpiece constant layer thickness distribution is achieved. This means that the workpiece to be coated should be able to be evenly coated with powder over its entire height.
  • the object is achieved by a booth for coating a workpiece with powder having the features according to claim 1.
  • the inventive cabin for coating workpieces with powder has a trough and a roller arranged therein.
  • the tub and the roller form a suction channel and a suction opening to suck off excess powder.
  • the roller is rotatably mounted.
  • the roller has a diameter which is smaller than the opening width of the trough.
  • the suction channel is arranged on the cabin floor.
  • the suction channel is arranged transversely to the cabin side wall.
  • the suction channel can also be arranged on or in the cabin side wall.
  • the suction channel runs vertically in the cabin side wall.
  • a further suction channel with a suction opening for sucking off excess powder and a door provided, by means of which the further suction channel is accessible.
  • the suction opening is provided in the door.
  • one end of the suction channel is connected to a cyclone and the other end of the suction channel with another cyclone.
  • the cabin according to the invention has a secondary filter which is connected to one end of the suction channel.
  • the blow bar is arranged in the region of the cabin opening.
  • the blowing strip has a plurality of blow strip sections and the blow strip is configured and operable in such a way that the blow strip sections can be operated sequentially. As a result, the amount of compressed air required to clean the cabin floor per unit of time can be reduced.
  • a control can be provided by means of which the blow strip sections can be controlled individually.
  • a further blow bar is provided and the suction channel is arranged between the two blower bars.
  • the suction channel is designed such that the opening width of the suction opening is adjustable. In this way, the amount of air extracted in the area of the cabin floor can be individually adapted to the respective needs.
  • the suction channel at the end of a lid with a lid opening wherein the lid is formed such that the opening width of the lid opening is adjustable. This also allows the amount of air extracted in the area of the cabin floor to be individually adapted to the respective needs. In addition, the lid can be removed to clean the suction channel.
  • the suction channel is advantageously made of steel or plastic. The advantage is that with these materials little or no powder adheres to the wall of the suction channel.
  • the cabin according to the invention can also have a manual coating booth.
  • the workpiece to be coated can be manually pre-coated or post-coated.
  • FIG. 1 1 shows a first embodiment of a cabin 1 according to the invention for coating a workpiece 11 in longitudinal section.
  • FIG. 2 shows the first one Embodiment of the inventive cabin 1 in plan view in section.
  • the workpiece 11 To coat the workpiece 11, it is first hung on a workpiece transport bracket 10.1, which in turn is attached to a conveyor belt 10 located above the car 1. The workpiece 11 is then transported on the conveyor belt 10 suspended by the car 1.
  • the arrow T indicates the transport direction.
  • the workpiece 11 is coming from the right first past a manual coater stand 5 and then transported through the section 39 of the car 1.
  • the workpiece 11 can also be transported in the reverse direction.
  • personnel 17 can precoat the workpiece 11 as needed. This is helpful if the workpiece 11 has undercuts that can not be coated with the automatic pistols 7 and 9 or only with great effort and loss of material.
  • the staff 17 uses a manual spray gun for pre-coating, which is not shown in the figures.
  • the workpiece 11 is transported via a cabin opening 22 in the section 39 of the car 1.
  • the further section 39 of the cabin 1 is bounded laterally by a first cabin side wall 2 and a second cabin side wall 3.
  • the cabin side walls 2 and 3 are hereinafter also referred to as side walls.
  • a first row of automatically operating spray guns 7 projects into the cabin 1.
  • the spray guns 7 are also referred to as automatic guns are mounted on a lifting device 6 and are controlled by a computer-aided control.
  • another series of automatically operating spray guns 9 projects into the cabin 1.
  • the spray guns 9 are mounted on a lifting device 8 and are also controlled by the computerized controller. With the help of the spray guns 7 and 8, the workpiece 11 is coated automatically.
  • the workpiece 11 is transported through a cabin opening 21 again out of the car 1 and fed to a furnace, not shown in the figures, so that the powder layer on the workpiece 11 liquefy and crosslink and can form a closed surface.
  • the cabin 1 is limited by a cabin roof 20. Down the car 1 is completed by a cabin floor 4.
  • the cabin floor 4 is also referred to below as floor in the following.
  • the bottom of the hand coater stand 5 can, as in the Figures 1 and 2 is shown slightly higher than the Kabincnboden 4 may be arranged.
  • the staff 17 can easily enter the Handbe Anlagenerstand 5, located on both longitudinal sides of the car 1 each have a staircase 18 and 19 respectively.
  • a suction channel 14 Transverse to the two side walls 2 and 3 runs at the cabin floor 4, a suction channel 14.
  • the longitudinal axis of the suction channel 14 thus extends transversely to the transport direction T of the workpiece 11. In other words, this means that the Longitudinal axis of the suction channel 14 extends parallel to the plane which is spanned by the cabin opening 21 and 22 respectively.
  • the suction channel 14 has two suction openings 14.1 and 14.2. One end of the suction channel 14 is connected to a cyclone 16 via a suction pipe 15 arranged outside the booth 1.
  • the suction channel 14 is formed by a trough 38 and a roller 35 arranged in the trough 38.
  • the diameter C D of the roller 35 is slightly smaller than the opening width 2 R of the trough 38 (see. FIG. 14 ), so that arise between the outside of the roller 35 and the two inner sides of the tub 38 slots, which form the suction openings 14.1 and 14.2.
  • both the roller 35 itself and the inner walls of the tub 38 opposite the roller are automatically cleaned in the region of the suction openings.
  • blow bars 12 and 13 extend transversely to the two side walls 2 and 3 on the cabin floor 4. In general, the blow bars 12 and 13 thus run parallel to the suction channel 14 Figures 1 and 2
  • the first blowing strip 12 extends from the first side wall 2 to the second side wall 3 and is arranged in the region of the booth outlet opening 21.
  • the second blow bar 13 extends also from the first side wall 2 to the second side wall 3.
  • the second blow bar 13 is arranged in the region of the cabin inlet opening 22.
  • the first blow bar 12 comprises two blow bar sections 12.1 and 12.2, through which compressed air L can be blown in the direction of the suction openings 14.1.
  • the Blasologicalnabête 12.1 and 12.2 are constructed so that they can be operated independently.
  • the second blow bar 13 also includes two Blasologicalnabête 13.1 and 13.2. By the two Blasologicalnabête 13.1 and 13.2 compressed air L can be blown in the direction of the suction openings 14.2.
  • the Blasologicalnabête 13.1 and 13.2 are constructed so that they can be operated independently.
  • the two blow bars 12 and 13 are thus arranged so that they blow compressed air L from the area of the cabin openings 21 and 22 to the interior of the cabin. This causes less powder to escape from the cabin 1 through the cabin openings 21 and 22.
  • the Zyklon 16 abqewandte end of the suction channel 14 is closed with a cover 23.
  • the structure of the lid 23 is in FIG. 10 shown and will be explained later.

  • FIG. 6 shows the third embodiment of the inventive cabin 1 in plan view in section.
  • the third embodiment differs from the second embodiment in that the vertically extending suction channels do not have doors 25. Satisfied that of the arranged in the side wall 2 suction channel 45 is formed by a vertically extending trough and a roller 46 disposed therein, the longitudinal axis 47 is rotatably mounted. The diameter of the roller 46 is smaller than the opening width of the tub. This results in between the roller 46 and the trough two vertically extending slots, which form the suction of the suction 45.
  • the suction channel 55 arranged in the side wall 3 is likewise formed by a vertically arranged trough and a roller 56 arranged therein, whose longitudinal axis 57 is rotatably mounted. Also ago are the two suction between the tub and roller. Through these exhaust openings and the suction openings 14.1 and 14.2 that excess powder is sucked, which floats in the cabin.
