Definitions

  • the present invention relates to a device and a method for cleaning a powder coating booth and a powder coating booth equipped with suction devices for suction or cleaning of Powder residue is equipped.
  • the suction devices drive to along the cabin walls.
  • the present invention is therefore the task underlying, an apparatus and method for cleaning to create a booth for powder coating, which eliminated these and other disadvantages.
  • the object is achieved by a device for cleaning a Cabin for powder coating with the characteristics of Patent claim 1 solved.
  • the inventive device for cleaning a cabin for powder coating has a mobile frame on, which is movable along the insides of the cabin.
  • the frame includes suction nozzles to remove residual powder from the insides to extract the cabin.
  • the task is also performed by a method for cleaning a booth for powder coating with the characteristics of Patent claim 13 solved.
  • the suction nozzles are arranged and the frame is formed such that the air directly at the Surface of the inside of the cabin is accelerated. This makes the insides of the cabin even better free from powder residues.
  • the frame has a wiper strip. Also this makes the insides of the cabin even better free from powder residues.
  • the suction nozzles on those sides of the frame are arranged, the ceiling, the side walls and associated with the floor of the cabin. This can be done in one operation the ceiling, the side walls and the floor the cab be cleaned at the same time.
  • a stationary suction chamber which has a Suction duct is connected to the frame.
  • the suction chamber comprises a movable belt with an opening into which the suction channel opens.
  • the frame inside a cavity, which with the Suction channel is connected.
  • the frame to be provided with a slot at the top. This has the advantage that the transport of the workpieces through the frame not hindered. If the system is in coating operation, the workpieces are going through the frame transported through.
  • the frame has the shape of the cabin.
  • the frame points on both sides of the suction nozzles respectively a groove into which the wiper strip can be inserted.
  • the frame have a transport suspension, by means of which of the frames is movable through the cabin.
  • the wiper strip have a sponge.
  • the suction devices to a Sliding frame attached, the side slits and inside a cavity for removing the sucked air having.
  • the frame is included in the invention Sponges equipped to complete the powder removal. These sponges are removable and can be attached the frame can be grown in two different places. You are in the frame feed direction advantageously behind the suction devices.
  • the powder coating equipment includes a cabin or a tunnel 1 with open ends.
  • the powder coating plant comprises also one or more conventional powder spray guns, which are not shown in Fig. 1, however.
  • the upper Side of the cabin is in its entire length by one Split 2 slot. Both drive through this slot 2 the funding for the parts to be coated as well the mobile cleaning device, which as a whole with designated by the reference numeral 3.
  • This mobile cleaning device 3 has a frame 4 with a cavity inside to the flow of the extracted Air on.
  • the frame 4 is like the inner profile shaped the car 1 and also has an upper opening 5 on to the above, not shown funding to let pass unhindered.
  • the suction chamber 13 is box-shaped and narrow and has two long and two short walls 18 with a slot 17 in between.
  • the slot 17 is as long as the cabin.
  • One annular metal band 14 is about pulleys or Deflection rollers 15 deflected and abuts against the walls 18.
  • the suction 12th is attached to the belt 14 in the region of the hole 16 and opens into the hole 16. Due to the negative pressure, which in the Suction chamber 13 prevails, the tape 14 remains against the the suction chamber 13 provided sealing edges of the walls 18th pressed.
  • the band 14 running on the pulleys 15, follows the movements of the mobile cleaning device 3.
  • the band 14 is, as mentioned, in the region of the hole 16th connected via the suction channel 12 with the frame 4 and thus creates a connection between the mobile suction means, which in the present embodiment by the frame 4 and the suction channel 12 are formed, and the fixed suction means, which in the present Embodiment formed by the suction chamber 13 become. This allows the air from the mobile suction flow to the fixed suction means.
  • the seal between the band 14 and the walls 18 takes place by the negative pressure that the suction in the suction chamber 13 generated.
  • the band 14 is due to the negative pressure constantly close to the edge of the opening 17.
  • the cleaning is done the powder coating booth fast and effective.
  • the cleaning takes place due to the extracted air, the sucked through the slot 7 on the mobile frame 4 Powder carries with it.
  • the frame 4 drives through the whole Cabin 1 through and sucks the entire on the cabin walls adherent residual powder in a single pass from. After the frame 4 has passed through the car 1, the cleaning process is completed until further notice.
  • the frame 4 remains, as shown in Figure 2, as long as outside the cabin 1 stand until another cleaning process is required.
  • a renewed cleaning of the car 1 by the frame 4 driven back through the cabin 1 through is then again to the original shown in Figure 1 Take position.
  • the extracted from the cabin walls powder is on the Slot 7, the existing inside the frame 4 cavity and the suction channel 12 is transported into the suction chamber 13. From there, the powder becomes a conventional one Powder recovery plant continued where it filtered and is cleaned.
  • the cleaning is done by the damp Sponge on the mobile frame 4 more effective. Also possible electrostatic fields caused by friction of powder particles be created on each other and on the cabin walls thereby degraded.
  • the invention is not limited to the use of sponges 10, which are attached to the frame 4, limited. in principle Any type of wiper strip can be used, which is suitable for the residual powder from the insides of the To wipe off cubicle 1.
  • the wet sponge 10 is in the first groove 8 (Fig. 4) or behind the suction.
  • the sponge 10 Before rewinding in the opposite direction will the sponge 10 is taken out of the groove 8 and into the Groove 9 on the opposite side of the slot. 7 put into it. As a result, the sponge 10 works alternately on the two sides, wear more evenly and thus has a longer life.
  • the sponge 10 can be in the groove 8 or 9 quickly and just insert it, because he is on a support strip 11 made of a flexible material, such as plastic or the like, is attached.
  • This carrier strip 11 is inserted into one of the grooves 8 or 9 and stops the sponge 10 firmly in position. Because the sponge 10 thicker than the space between the mobile Frame 4 and the cabin wall, it is flattened and bends when the frame 4 into the cabin 1 inside moves. This is the contact between sponge 10 and the walls guaranteed at all times.
  • the in the conventional Method piston used are no longer required what among other things to a space savings leads. Because the sponge 10 at the frame corners no piston stroke exposed, he can without a risk of tearing one consist of single strips.
