Definitions

  • the invention relates to a booth for powder coating of workpieces according to the preamble of claim 1 and claim 2.
  • the cabin interior is delimited by side walls, end walls on both sides, a cabin floor and a canopy which is divided by a longitudinal gap ( EP-A-0 839 582 ; DE 195 24 327A ).
  • the cabin has in its upstream and upstream end walls each have a passage opening for the workpieces.
  • a manual coating space is provided in each case.
  • the cabin floor has in its center a suction for fallen or removed in a cleaning of the cabin interior of the walls excess powder.
  • the suction opening is connected to a suction line, which is fed under the cabin floor.
  • the invention has the object of providing a cabin of the type mentioned in such a way that the escape of powder particles in the environment of the cabin reduces and still an unimpeded hand coating high quality economically, i. in particular with the lowest possible extraction power can be achieved.
  • the suction opening is located in the end wall, so next possible to the associated manual coating space. This is advantageous because the suction decreases with increasing distance of the suction opening of the manual coating station, so would have to be installed to produce the same suction effects so larger suction.
  • a second manual coating station downstream of a second passage for the workpieces in a second end wall at the downstream end of the cabin is advantageous when there is a need for post-coating or automatic coating control in the cabin.
  • This hand coating station can also be provided as the only manual coating station.
  • lamps for illuminating the coating locations can be provided on the outside of the cabin.
  • the unavoidable lighting inside the cabin can thus be carried out as ceiling lighting, i. be attached to a pollution-prone site.
  • the cabin shown in the figures is used for coating of dash-dotted lines indicated workpieces W, which are conveyed along a likewise dash-dotted line transport path T in the direction of the corresponding arrow through the cabin continuously or gradually.
  • the cabin has two side walls 2, which with vertical slots 4 for passing in Fig. 1 arranged, vertically movable automatic powder spray guns 6 are provided.
  • the cabin further has a canopy 8 divided by a longitudinal gap S.
  • the longitudinal gap allows hangers 10 for the workpieces W to allow the transport of the hangers 10 with the workpieces W hanging therefrom through the car along the transport path T.
  • the cabin further has a bottom 12 and a front end wall 14, which in the Fig. 1 and 3 is arranged at the left end of the cabin, as well as a rear end wall 20, which in on the Fig. 1 and 3 Seen right end of the cabin is arranged.
  • the end wall 14 has a large passage opening 16 which is significantly larger than the transverse profile of the workpieces W (s. Fig. 2 ). This passage opening 16 can be closed by a sliding door 18 for the cleaning operation, via which the walk-in cabin interior is accessible.
  • the rear end wall 20 has a für Stammsö Maschinenmaschine Maschinen19, which may be sized as well as the passage opening 16 for passing the workpieces W out of the cabin. A door may be missing here in particular if an exhaust is provided near the front end wall 14.
  • a designated generally by the reference numeral 30 Handbe Anlagenllsplatz is arranged with a feet supported on 32, accessible floor 34, which is above the cabin floor 12 and of the in Fig. 2 right side of the transport path T wallless, so is freely accessible.
  • a rear wall 36 is provided, which in its upper region to a partial roofing 38 of the manual coating station in the four different embodiments according to the Fig. 5a ) to 5d) is bent and parallel to the transport path T directly to the in Fig. 2 seen left edge of the gap S for passing the suspension device 10 for the work W extends.
  • the sliding door 18 is in its upper, in Fig. 2 left area 18 'of the contour of the partial roofing 38 profiled accordingly. Since the profiling of the sliding door 18 is adapted to that of the rear wall 36 and part roofing 38, can be achieved by using a seal 39 (in Fig. 5a) to 5d ) indicated) achieve an optimal cleaning effect with the sliding door 18 closed.
  • a suction line 50 performed below the floor 34 closes at an opening 52 in the front end wall 14 of the cabin at.
  • Suction line 50 is connected to a waste powder filtration or recovery unit (not shown).
  • a second manual coating station 40 is located downstream of the cab with a floor 44 on feet 42 which is accessible from the opposite side as the manual coating station 30 and also provided with a back wall 46 having a partial roof 48 ,
  • the suction line 50 could also connect via an opening below the stand 44 in the rear end wall 22 to the cabin interior.
  • the manual coating station 30 has seen a larger dimension L in the transport direction T than the corresponding dimension 1 of the manual coating station 40, because near the suction opening 52, the suction through the passage opening 16 into the cabin is stronger than the suction through the passage opening 19.
  • the coater can thus work at this end of the cabin at a greater distance from the passage opening than at the other end of the cabin and has correspondingly greater freedom.
  • At least the cabin walls 2, 14 20, the car roof 8 and the rear walls 36, 38 and 46, 48 made of an electrically non-conductive material.
