Definitions

  • the invention relates to a system for surface finishing in batch operation, consisting of at least one grinding wheel and parts to be machined, working with a loading unit, and a separating arrangement associated therewith.
  • the object of the invention is to design a system of the type mentioned above in such a way that part mixtures and the setting of undersize in the parts to be worked are avoided and at the same time the economy is significantly increased while significantly reducing the separation time.
  • This object is achieved according to the invention essentially in that the separating arrangement is separated from the working container and fed via a buffer container, the capacity of which corresponds at least to that of the working container, that the mixture of parts and grinding wheels can be transferred from the buffer container to the separating arrangement in metered amounts and that Arrangement for returning the grinding wheels separated from the machining parts is provided.
  • Fig. 1 shows a tandem system, consisting of two circular vibrators 1, which are arranged on both sides of a loading unit 3 and can be filled from this loading unit via a pivotable sieve channel 4 with grinding wheels and parts to be machined.
  • Each circular vibrator 1 is provided on the bottom side with an outlet opening which can be opened and closed via a cylinder-piston arrangement 2.
  • the opening is dimensioned so that the circular vibrator can be emptied within a very short time.
  • Each circular vibrator 1 is followed by a buffer container 5 into which the circular vibrator can be emptied.
  • the buffer container 5 is equipped with a vibration drive, which ensures that a defined supply of the mixture to the subsequent vibrating screen 6 is possible.
  • the buffer container 5 is pivotally mounted and preferably has a rising inclined surface on the inside of the sieve, which, depending on the inclination of the container and the drive, ensures that only one layer of the mixture reaches the vibrating sieve 6 and thus optimal separation is possible. Since the vibrating screen 6 can be dimensioned completely independently of the processing units, the optimal size can also be selected without problems.
  • the buffer container 5 can also be swiveled up in the direction of the screen surface 6 in such a way that a perfect and complete emptying of the buffer container is ensured after each batch.
  • the vibrating screen 6 is followed by a conveyor belt 7 for removing the parts.
  • a conveyor belt 7 for removing the parts.
  • any other suitable receiving device can also be used instead of a conveyor belt.
  • a return belt 8 is provided for the grinding bodies, which makes it possible to carry out a direct return or a return to the loading unit 3 via a lifting and tilting unit.
  • the parts to be machined can be transported via schematically indicated boxes.
  • a large-area undersize screening is preferably carried out in the area of the grinding wheel return, which has a particularly advantageous effect for the entire process sequence, since this undersize screening can be carried out optimally and completely due to the large available areas and thus eliminates the risk of undersize in parts of the next batch states.
  • FIG. 2 shows a system corresponding to the basic structure of the system according to FIG. 1, in which, however, centrifugal force grinding units 9 are used instead of circular vibrators. These centrifugal machines are preferably pivotally mounted so that the respective contents of the machine 9 can be tilted directly into the subsequent buffer container 5.
  • the emptying of a round vibrator in a system according to FIG. 1 can be carried out without problems within only about 2 minutes, and only a time span of this magnitude is also required for the filling.
  • Both systems shown in FIGS. 1 and 2 have in common that there is no mixing of parts between successive batches, that the processing containers can be emptied in a very short time, that the separation is metered and single-layer and separated from the Processing container is feasible, that a very large-sized undersize screening is provided and that overall there is a very substantial time saving, so that one can achieve, for example, a result with four machines for which practically six machines would be required according to conventional technology.
  • FIG. 3 shows a series of boxes 10 which can be operated in the manner of a shift register and which are filled with grinding wheels and parts to be machined. These boxes can be emptied into a subsequent processing unit, in particular a centrifugal force grinding machine 9, the parameters P, such as compounds, running time, speed and the like, being set as a function of the respective filling. This setting is preferably carried out fully automatically via a coding provided on the respective box 10.
  • the emptied boxes are removed in the form of empty containers 11.
  • the mixture passes from the processing unit 9 into a buffer container 10, which is designed in accordance with the buffer containers described with reference to FIGS. 1 and 2.
  • the buffer container 5 is followed by a sieve arrangement 6, which is metered from the buffer container 5.
  • the screen system 6 is preferably a movable screen arrangement, so that the optimum screen can be selected and automatically brought into the correct position in accordance with the respective composition of the mixture of machined parts and grinding wheels. This control also preferably takes place as a function of the coding of the loading boxes 10 also to carry out magnetic separation in this area.
  • a row of empty boxes 13 is provided for receiving the machined parts, and in the path of these boxes 13 loaded with the machined parts, for example, a diving station and a hot air blower 14 can be provided.
  • the buffer tank 5 and the screening plant 6 are provided with their own vibration drives, which can be controlled according to the respective circumstances.
