Definitions

  • the invention relates to a ring trough-shaped vibrating scouring container according to the preamble of the main claim.
  • the backflow prevention barrier consists of a thin wall upright on the ramp in the region of one side edge of the ramp.
  • the container contents overflow this wall from the free side ramp of the wall.
  • the backflow prevention effect is not optimal and can only be brought into justifiable areas by the fact that, opposite the ramp, additional walls project downwards from the ceiling in the direction of the ramp.
  • the correspondingly vertical wall also forms a disturbing obstacle to the expenditure of the container contents, so that a space is easily formed in the area immediately upstream of this wall and often traps individual workpieces, especially specifically heavier workpieces behind the wall, and thereby be excluded from the spiral movement of the entire container contents.
  • the object of the invention is based on the design of a ring trough vibrating scouring container of the required type in a technically simple manner in such a way that corresponding dead zones are avoided so that rolling bodies, in particular balls, can also be completely removed.
  • a ring trough vibration scrubbing container of increased use value is specified.
  • the range of workpieces to be surface-treated is considerably enlarged. Even rolling bodies, in particular balls, can now be machined and also completely removed. This is achieved by using the special backflow prevention barrier.
  • the top of the container overflows when the ramp is activated. The movement component occurring from the outside in during the spiral movement of the container contents is converted into an upward component in the area of the plate. As a result, the workpieces that reach the top of the plate are already supported. Another upward component with constant displacement in the direction of the separating screen results from the arrangement of the backflow-preventing side wall.
  • the one side wall of the triangular plate extends in the region of the side flank of the ramp and the sliding surface is obtuse-angled ensures that the workpieces and machining bodies reaching the sliding surface exert a certain advance on the workpieces located on the plate and thereby support the discharge . Wear is reduced. If the backflow-preventing side wall and sliding surface are at an acute angle to one another and the edge length of the sliding surface is greater than that of the side wall, further improved conditions for the sliding over of the container contents result. Due to the design that the ramp has two stub axles as a holding axis for fishing bags, a ring trough vibrating scouring container of a simplified design is specified.
  • This design of the ramp also allows it to be used at a convenient location in the container trough. If the removal of the workpieces is desired, the ramp is immersed in the medium at any point in the container channel. It then moves, due to the helical movement of the medium, into its discharge position limited by the catch pockets. There is no need for tedious insertion of the stub axles. The ramp can therefore be inserted very easily.
  • the construction is very simple, weighs little and therefore does not distort the vibrations. E.g. it is possible to insert the ramp into the container channel immediately behind the separating screen discharge section. It then moves with the contents of the container almost over the full length of the channel. This measure can be taken if workpieces are treated in a single cycle.
  • the floating ramp does not affect the transport movement of the container contents. Furthermore, the ramp in the arch. be shaped area of the container channel are brought into effect. Then only the corresponding ramp side flanks have to be adapted to the curvature of the ring trough vibrating scouring container. This is a long time measured sieve section possible, which does not have to protrude far beyond the edge of the container. If the stub axles then sit on tabs projecting upward above the upper edge of the ramp, it follows that the upper edge of the ramp can lie at a corresponding distance below the upper edge of the channel. It cannot happen that when the workpieces are discharged, processing bodies or workpieces get over the upper channel edge. Handling advantages arise when the two tabs are connected to form a handle.
  • the catch pockets are arranged on the upper gutter edge.
  • the catch pockets are formed by strips which overlap the upper edge zones of the sieve box side walls. In this way, the strips have a double function. On the one hand, they form the catch pockets and, on the other hand, they still serve to hold the box in place.
  • the ramp lies in the arch region of the channel, has correspondingly rounded side flanks and the sieve section is tangential to the course of the ring trough.
  • the sieve section allows the sieve section to be dimensioned very long, nevertheless allowing it to protrude little above the container and still using a ramp with curved side flanks; furthermore, these measures do not result in dead corners in which the contents of the container collect and are not discharged.
  • the apex line of the dam is approximately tangential to the inner wall of the container and parallel to the connecting line of the catch pockets, so as to encourage the contents of the container to emerge from the dam.
  • the ring trough vibration scrubber 1 is part of a surface processing machine.
  • the same has a base frame 2 which contains the drive (not shown) and which supports the ring trough vibrating scouring container 1 via compression springs 3.
  • the vibration generator excited by the drive, not shown, which is also not illustrated, is attached centrally to the ring trough vibration scrubber.
  • the bottom 4 of the container trough runs horizontally and merges into the outer wall 6 of the container via a curve 5.
  • the container inner wall 7 extending from the container bottom 4 without a curved transition zone extends concentrically to this. If required, the container trough can be provided with an elastic lining (not shown).
  • a separating screen discharge section 8 extends in a tangential arrangement to the ring trough course of the container trough. Its inner end 9 lies radially with respect to the ring trough vibrating scouring container 1, while the outer end 10 projects over the container outer wall 6.
  • the cantilevered area of the separating screen discharge section 8 is underpinned by a sliding wall 11, which slopes obliquely downwards to the center of the container.
  • the separating screen 12 forms the bottom surface of an inserted box, which is U-shaped in cross section.
  • the box side wall 13 facing the container outer wall 6 is bent at a right angle, and the bent edge zone 14 lies on the upper channel edge R.
  • This edge zone 14 of the box is overlapped by a bar 15.
  • a further bar 16 extends parallel to this bar and extends over the edge zone 14 'angled from the inner, sieve-like box side wall 17. This makes it possible for the processing bodies K located in the ring trough vibrating scrubbing container and reaching the separating sieve discharge section 8 to be returned to the container channel both through the sieve 12 and through the side wall 17 of the box.
  • the two strips 15, 16 form open catch pockets 19 at the radial level of the ring trough vibrating scouring container 1 against the conveying direction x of the container contents. This is achieved by a multiple angling of the free ends of the strips 15, 16 in connection with the upper channel edge R.
  • the multiple bend is such that the outer end 20 of the strips 15, 16 forms a funnel-shaped catch pocket 19 in connection with the upper channel edge R.
  • the section 21 of the strips 15, 16 which adjoins the outer end 20, on the other hand, is arranged parallel to the upper channel edge R.
  • the internal dimension between this section 21 and the upper channel edge R corresponds to the diameter of two stub axles 22, which represent the holding axis of a ramp 23 lying transversely to the channel.
  • the stub axles 22 are seated on tabs 25 projecting upward above the upper edge 24 of the ramp 23.
  • the latter extend when the ramp 23 is inserted in the interior of the container and are shaped such that they overlap the box side walls 13, 17. Furthermore, the upper edge 24 of the ramp 23 overlaps the inner end 9 of the sieve 12.
  • the tabs 25, which extend approximately to the edge of the groove R, are connected to form a handle bracket 26 projecting beyond the edge R of the groove.
  • the ramp 23 in the arch region of the container trough extends. Accordingly, it has rounded side flanks 27 and 28.
  • the lower edge 29 of the ramp 23 runs parallel to the upper edge 24 of the ramp and is seated on the apex line 30 of a dam 31 on the bottom.
  • This apex line 30 is approximately tangential to the container inner wall 7 and parallel to the connecting line of the catch pockets 19.
  • the rise and fall angles of the dam 31 are approximately 20 °.
  • the side flanks 27, 28 are such that, when the ramp 23 is inserted, there is a flush contact between the inner container wall 7 and the outer container wall 6. Furthermore, the lower edge 29 of the ramp sits on the apex line 30 of the dam, while the stub axles 22 have entered the catch pockets 19.
  • the ramp 23 has on its side wall 27 facing the container inner side 27 a backflow prevention block S overflowed by the container content.
  • This is formed by a plate 33 which u. a. has a side wall 32; the latter begins in the middle of the ramp area M and rises at an angle towards the inner wall 7 of the container.
  • the other side wall 34 of the plate 33 runs in the area of the inner rounded side flank 27 of the ramp 23.
  • the third wall 35 which runs obliquely downwards from the middle of the ramp area M to the side flank 27, is designed as a sliding surface which is at an obtuse angle to the ramp surface.
  • the side walls 32, 34 are perpendicular to the ramp surface running in one plane.
  • the side wall 32 merges into the inner tab 25.
  • the triangular plate 33 can either be designed as a separate part and connected to the ramp 23. However, there is also the possibility of designing the plate 33 and ramp 23 in the same material.
  • the ramp 23 is not used. The container contents can therefore not reach the separating sieve discharge section 8.
  • the ramp 23 is to be used at one point of the ring trough vibrating scouring container 1 in such a way that the stub axles 22 rest on the upper channel edge R.
  • the ramp 23 moves due to the movement of the container contents in the conveying direction x, so that the stub axles 22 enter the catch pockets 19. Due to the pressure of the container contents, the lower edge of the ramp edge 29 then touches the apex line 30 of the dam 31.
  • the contents of the container now overflow the ramp 23 and the top of the triangular plate 33 and reach the separating screen discharge section 8, the separation between the processing bodies and workpieces 36 taking place.
  • the processing bodies fall through the sieve 12 while the workpieces are being discharged.
  • the discharge of the balls 36 can be optimally achieved because of the use of the triangular plate 33. It has the effect that the movement component occurring during the spiral movement from the outside in is converted into an upward component. Furthermore, the sliding surface 35 leads to a feed in the direction of the arrow y. This effectively prevents the spherical workpieces 36 reaching the ramp 23 from migrating down the ramp. The spherical workpieces 36 are accordingly conveyed up the ramp and reach the separating screen discharge section 8, which would not be possible without the use of the backflow prevention lock S.
  • the triangular plate 33 with guide step and the other walls is also suitable for processing other rolling elements.
  • the ramp can then be easily removed from the ring trough vibrating scouring container 1 by means of the handle bracket 26.
