Definitions

  • the present invention relates to a deburring, satinizing and polishing machine with a conveyor belt drive according to the preamble of claims 1, 6 and 9.
  • the polishing medium is circulated by means of an endless conveyor belt in a trough-shaped polishing trough.
  • This conveyor belt slides on the round wall of the polishing trough, which in turn is located in a tightly closed water container that also serves as a machine frame.
  • the conveyor rollers necessary for the conveyor belt are stored outside on the water tank.
  • this construction has the disadvantage that the polishing material has to be laboriously collected by hand after the polishing process, which is very time-consuming, especially for small parts such as cutlery or jewelry. Also, when changing the polishing medium, the polishing media must be removed manually from above with small buckets. On the other hand, the previous construction does not offer the user access behind and under the polishing trough for the periodic cleaning of the water container, where soap residues and other soiling are inevitable. In addition, the conveyor belt can only be changed by disassembling the polishing trough and the conveyor rollers. Another major disadvantage of this construction is the relatively high demand for soapy water and its disposal.
  • the aim of the present invention is to further develop the known polishing machines with a conveyor belt drive in such a way that they become much more user-friendly and also more maintenance-friendly.
  • the advantage of the polishing machine according to the invention is that by using a basket or cage after the polishing process has ended, the polishing material can be separated from the polishing medium in a simple and rapid manner.
  • polishing medium remaining in the polishing trough can be removed quickly and easily from the polishing trough and even sorting out the polishing medium according to the size of the polishing bodies is possible.
  • Another advantage is that quick access to the inside of the machine and economical use of polishing solution is achieved.
  • a special container element in the form of a basket 28 is provided for the rapid removal of the polishing material, which is integrated into the polishing trough 2 during or after the polishing process has ended.
  • the semicircular basket 28 with opening and two handles 26 in its semicircular wall 24 is matched as closely as possible to the diameter of the trough-shaped polishing trough and consists of a wire mesh or mesh.
  • the basket is placed with its opening facing down into the polishing trough 2 on the polishing medium 21.
  • the basket 28 is also driven by the rotation of the conveyor belt 9 and the polishing medium 21, so that the polishing medium including the material to be polished (or repeatedly) fall into the basket.
  • the machine After the polishing process, the machine is stopped exactly at the point in time when the handles 26 of the basket 28 point upwards.
  • the polishing bodies fall through the mesh of the grid, while the polishing material remains in the basket.
  • the mesh size of the wire mesh is adapted to the size of the polishing material in order to keep the resistance when lifting as low as possible.
  • a perforated plate with the largest possible opening can also be used.
  • the end faces 25 of the basket 28 do not require passage openings for this function. However, in order to keep the weight of the basket as low as possible, it is more advantageous to also provide the end faces 25 as a wire mesh.
  • the handles 26 can also be attached to the semicircular wall 24. To reduce the effort required when lifting, several of these baskets can be used side by side instead of one. This will be the case in particular if, instead of the polishing material, heavy polishing medium 21 such as steel itself has to be removed. For this purpose, one chooses passage openings that are smaller than the polishing body 21, or dispenses with any passage opening at all.
  • FIG. 4 Another variant for the rapid separation of the polishing material from the medium 21 is a semicircular cage 29 (FIG. 4) which is closed on all sides, the semicircular wall 24 of which is matched as closely as possible to the diameter of the polishing trough 2 and the flat wall 27 of which is made of a wire mesh, mesh or a perforated plate with the largest possible passage.
  • the semicircular wall 24 is rubberized to give as much hold on the conveyor belt 9.
  • the cage 29 with the flat wall 27 is placed on the polishing medium 21.
  • the cage 29 is also driven by the rotation of the conveyor belt 9 and the medium 21.
  • the polishing material is pushed in front of the cage, while the polishing bodies 21 fall through the mesh of the flat wall 27 into the cage.
  • the polishing material lies above the polishing medium and can be collected easily.
  • the end faces 25 and the semicircular wall 24 do not require any through openings, but are also advantageously made of wire mesh in order to keep the weight as low as possible.
  • both the basket 28 with opening and the cage 29 which is closed on all sides not only enable the polishing material to be separated, but also to sort out large and small polishing particles if the mixture of the polishing medium is to be changed.
  • a new design is planned for more economical use of polishing solution and for quick access to the inside of the machine.
  • the machine now only consists of a tubular frame 1 as a chassis, in which the trough-shaped polishing trough 2 is located. This is only screwed to the base frame on a single face. All conveyor rollers 6, 22 rotating on the running side of the conveyor belt are mounted directly on the polishing trough 2. For this purpose, the end faces of the polishing trough have a carrier profile 3 on the left and right.
  • the conveyor belt 9 itself is only under full tension within the polishing trough 2 between the two upper conveyor rollers 6, 22 due to the weight of the polishing medium 21, while it is no longer under tension under the polishing trough.
  • the former tensioning roller now only takes on the leveling function 22, 23 for centering the belt, and instead of rotating rollers, the rib reinforcements 20 below the polishing trough also serve as sliding surfaces for deflecting the conveyor belt 9. Since this is not under tension in its entire circumference the direction of rotation is given in a single direction.
  • the endless belt is rotated via the drive roller 6 and pulls the polishing medium with it as tension. So that the conveyor belt 9 is held in its position and is protected against the penetration of polishing bodies between its running side and the sliding surface of the polishing trough, an insertion wall 4 with a flat profile by means of at least one cam 5b and a wing screw are on both end faces of the polishing trough 5a attached.
  • a collecting tray 13 is attached to the base frame 1 below the polishing trough for falling grinding dust (in the dry process) or dripping polishing solution (in the wet process). This is advantageously presented in the form of a pull-out drawer so that cleaning is possible at any time.
  • a small circulation pump is also provided in the engine compartment, which continuously conveys the dripping polishing solution from the drip tray back into the polishing trough.
  • a valve 12 is available directly on the polishing trough for changing the lye, so that the lye can be drained both into the collecting pan underneath for disposal or directly into the sewage system. Since only the polishing trough is filled with polishing liquor, the need for water and polishing soap is reduced to a sixth compared to conventional construction.
