  • the housing has a top wall 16, an inlet side Transverse wall 18, an outlet-side transverse wall 20, parallel to the direction of conveyance of the sheets (indicated by arrow 22) extending side walls 24 and a bottom wall 26, which at the same time as a collecting tub for not from the sheet metal pieces 12 entrained litter oil is used.
  • Transport rollers are located in the side walls 24 of the housing 10 28 stored, which is a horizontal funding level for specify the sheet metal pieces 12.
  • the transport rollers 28 are driven by a common toothed belt 30 which the output gear 32 of a not shown Drive motor works.
  • the entry-side transverse wall 18 consists of two pivotable Doors 34, 36, which are mirror images of through the transport rollers 28 arranged conveyor plane are.
  • the exit-side transverse wall 20 is a mirror image of the Cross wall 18 constructed from two doors 38, 40.
  • the door 34 (see FIG. 4) has an outer wall 42 and one inner wall 44 spaced therefrom from the interior of the housing upper ends of outer wall 42 and inner wall 44 are connected by an edge wall 46.
  • edge wall 46 To the front or ends of the door 38 to be thought behind the plane of the drawing, 40 is that through outer wall 42, inner wall 44 and edge wall 46 channel formed by end walls 48 in the longitudinal direction of the channel locked.
  • the inner wall 44 an upper wall portion spaced more from the outer wall 50 and just a little bit from the outer wall 42 spaced lower wall section 52.
  • the lower ends of outer wall 42 and wall section 52 define one Suction slot 54.
  • the wall sections 50 and 52 are through an oblique central wall section 56 connected, such that the transverse cross section of the door 34 one Rectangle with a right-angled triangle and corresponds to the beak carried by the latter.
  • connection opening 58 In the wall section 50 there is a close to its edges extending connection opening 58 is provided.
  • the door 34 is over at its upper outer end a hinge 60 is pivotally attached to the housing 10.
  • the closed position of the doors is shown in FIG.
  • Each of the doors can hinge around the associated one be pivoted away from the housing to access the Preserve the interior of the housing.
  • Suction shafts are provided, and the suction shafts are over Lines 70, 72 with the input of an electrostatic filter 74 connected. Its output is one with the input Suction blower 76 connected.
  • a hollow profile 78 is provided inside the housing 10 , which limited a compressed air channel 80.
  • the hollow profile 78 carries via solenoid valves 82 spray heads 84, which under regular Distance along the hollow profile 78 are distributed.
  • a second hollow profile 86 is thermally conductive with its underside placed on the top of the hollow profile 78. It delimits a lubricant channel 88.
  • the latter is connected by hoses 90 to injectors 72 which correspond to injection nozzles used in diesel engines and serve the that supplied via the lubricant channel 88 Atomize lubricant finely.
  • the one from the compressed air duct 80 via the solenoid valves 82 to the spray heads Air supplied serves to support the nebulization and the mist cone generated by the injectors 92 14 to shape, in particular to flatten.
  • the injection nozzles 92 extend with their end section through matching openings in a section 96 an angled shield 98.
  • the section 96 of the shield plate 98 is inclined so much that larger drops of lubricant that grow together of fog droplets on the shielding plate, below Drain gravity down along the sheet.
