They are used to move the three spindles (not shown) to which at least one workpiece to be machined (also not shown) is attached. Between at least one receiving location of the spindle, such as C 1 or a delivery location, such as D 1, and an immersion position of the workpiece attached to the spindle in the abrasive bed 2.
  • the symbols T 1 , T 2 and T 3 schematically show that of each one Spindle-fastened workpiece traveled there and back, before and after its processing by means of vibratory grinding.
  • the raw workpieces to be machined are represented by hatched triangular surfaces and the finished workpieces are represented by hatched circular surfaces.
  • the conveyor belt 5, which moves a workpiece to be machined in accordance with arrow f 2 is stopped by a control known per se, the description of which is superfluous, as soon as one of the workpieces to be machined has arrived at the transfer device T 0 .
  • the control mentioned above stops the rotation of the turntable in such a way that a receiving space (for example C 1 ) is located at the level of the transfer device T o .
  • the situation described corresponds in particular to the position of elements 3 and 5, which precedes that shown in FIG. 1.
  • the workpiece to be machined is then brought from the conveyor belt 5 to the now free receiving space C 1 of the turntable by means of the transfer device T.
  • the control mentioned above then causes the turntable 3 to rotate through an angle of 60 ° in the direction of the arrow f 1 , such that the receiving location C 1 of the turntable 3, which now carries a workpiece to be machined, causes the device T 1 to move the Facing spindle.
  • the device T 1 then moves the workpiece to be machined from the receiving location C 1 into the container 1, where the workpiece is completely immersed in the abrasive bed 2.

  • the fifth step that is, when the task location D 2 ', which is now empty, is opposite the device T 1 , the latter automatically lifts out the workpiece that was previously immersed in the abrasive body bed and whose surface grinding processing has ended, and then places it to the delivery point D 2 .
  • the turntable 3 is rotated again by five steps until the delivery location D 2 with the finished workpiece is again at the level of the transfer device T 0 , which places the workpiece in the compartment of the conveyor belt 5, which is empty and opposite the transfer device stopped.
  • FIG. 1 shows the situation at the moment already mentioned, in which a finished workpiece is transferred from the delivery location D 1 into the free compartment of the conveyor system by means of the transfer device T 0 .
  • the situation shown in Figure 1 otherwise corresponds to an operating state of the machine, which is sufficiently long after the start of operation, so that at this moment all subjects of the conveyor system 5, which are in the direction of conveyance (arrow f 2 ) in front of the empty compartment - in the
  • the content of the delivery point D 1 is to be handed over - is occupied with workpieces to be machined, while all the compartments which are behind the empty compartment are occupied with finished workpieces.
  • all of the receiving locations C 1 , C 2 and C 3 are occupied with workpieces to be machined and can be transferred to the container 1 during the temporary standstill of the machine, where they are subjected to the finishing grinding.
  • the delivery points D 2 and D 3 are occupied with workpieces that have already been finished and are gradually transferred to the conveyor system 5 by means of the transfer device T. if it is opposite the transfer device during the further rotation of the turntable 3.
  • the described mode of operation presupposes, of course, that the machine according to the invention is equipped with a device which synchronizes the gradual movement of the conveyor system 5 and the gradual rotation of the turntable 3 as well as the devices for moving the spindles T 1 to T3 and the transfer device T o .
  • the devices for moving the spindles T 1 to T 3 are caused to deposit the finished workpieces simultaneously on one of the two N synchronous stops, which follow one another, according to the outer arrow at the symbols T i to T 3 , and then at the immediately following stops, simultaneously pick up the workpieces to be machined from the task locations C 1 to C 3 , according to the inner arrow at the symbols T 1 to T 3 .
  • FIGS. 2 to 4 the individual parts of the machine are provided with the same reference numbers as were already used in the description in FIG. 1. It is therefore unnecessary to describe these parts again.
  • Figures 2 and 3 show in detail a possible embodiment with three devices for moving the spindles T 1 to T 3 , it being assumed that they are arranged identically and evenly distributed among each other, above the circle Shaped container 1 with a mutual angular distance of 120 °
  • the schematic representation of Figure 4 relates only to one of the three devices for moving the spindles, for example on T 1 .
  • the second slide together with the spindle 10 and the geared motor can be moved along the vertical guide rail 8 up or down as required, as indicated by the arrow V.
  • Another actuating cylinder allows the arrangement consisting of the first carriage 7 and all parts which it carries (8, 9, 10, 11a, 11b, 12) to be displaced along the first horizontal guide rail 6 in such a way that the spindle 10 both over can be brought to the container 1 as well as outside of its scope.

  • the finish grinding results in the illustrated embodiment by the rotation of the grinding bodies as a result of the rotation of the container 1 about a vertical axis and in that gradually all sides of the workpieces to be machined are exposed to the flow of the abrasive bodies, namely as a result of the rotation F that the geared motor 12 causes on the spindle 10.
  • the control mentioned above stops the geared motor 12 and switches on the actuating cylinders, also mentioned above, so that the workpiece attached to the lower end of the spindle carries out a spatial movement, which is shown as a chain line in FIG. 4 and is designated by t .
  • the workpiece is moved by means of the lower end of the spindle from the position P 1 , where it is immersed in the abrasive bed 2, to a position P 2 , which is located above the upper edge 1a of the container 1, specifically due to an increasing movement of the second slide 9 along the vertical guide rail 8.
  • the workpiece is moved to the position P 3 , which is located above the turntable 3, namely due to a movement of the first slide 7 along the horizontal guide rail 6 from the right to left in Figure 4.

  • the present invention is not limited to the embodiment just described. It includes all variants.
  • the means for charging and decharging the devices for moving the spindles can be chosen freely. Instead of a single conveyor belt 5, which brings the workpieces to be machined and the finished workpieces away, separate conveyor belts can be provided for these two functions, which work accordingly with the turntable 3 by providing two separate transfer devices, both of which are designated by T. .
  • T two separate transfer devices
  • Numerous known and different embodiments are suitable for this transfer device T 0 itself, which need not be described in detail here. You can use any known manipulator or stationary robot. Of course, it is also possible to have the transfer work between the turntable 3 and the straight conveyor belt or belts 5 carried out by a worker.
  • the turntable 3 and the conveyor belts that operate it can also be replaced by the same or a double number of conveyor belts per moving device such as T 1 to T 3 , the charging and decharging processes being carried out for each moving device by one or two linear conveyor systems have to.
  • the movement sequences of the various conveyor systems must then be synchronized in order to ensure the charging and decharging of the movement devices such as T 1 to T 3 .
  • the movement devices must be arranged in such a way that they fix the movements of the spindles and of those attached to them Workpieces take place in a plane approximately perpendicular to the side wall of the container or, in the case of a circular container, in a radially oriented plane.
  • the container can nevertheless have a circular outline or one in the form of a regular polygon with N sides.
  • the N spindles as well as the associated movement devices can then be arranged in planes that intersect the radii of the circular or polygonal container or that intersect the perpendiculars on the sides of the polygonal container.
  • the present invention is applicable to containers with any floor plan, for example also with a rectangular floor plan.
  • a turntable that surrounds the container can only be provided for a container with a circular or polygonal outline.
  • N pick-up and N delivery places can be provided alternately on the turntable, in such a way that each place has the same distance from each succeeding and preceding one.
  • the control mentioned above can be set up in such a way that the motor causes the turntable to rotate through an angle of 180 ° / N during the downtime of the dispensing spindles located above the turntable.
  • the movement devices T 1 to T 3 can also be designed differently than described above. Instead of spindles which are driven in such a way that they impart a slow rotational movement to the workpieces to be machined, such driven spindles can also be used that the workpieces are imparted different relative movements with respect to the grinding wheels. It can be, for example, any directional oscillating movements or also translatory movements.
