Definitions
- the present invention relates to a vibratory vibratory grinding machine with a container for receiving the bulk material and a vibratory drive.
- Such machines are known, for example from CH-A 458 103 and CH-A 511 675.
- Such machines have a vibrator trough in which the bulk material, i.e. The piece goods to be processed are vibrated together with solid carrier material and any additives in order to deburr, smooth, grind and polish the piece goods.
- this machine has a drain device which is arranged on the side wall of the container. This drain device has, among other things, a pin that has to be unscrewed if one wants to empty the container.
- FIG. 1 showing in section a container of a machine according to the invention
- FIG. 2 an embodiment variant.
- FIG. 1 shows a container 1 and a vibration drive 2 known from the patents cited above.
- the container has a coreless base 3 which, in the present example, is slightly concave in the middle, that is to say with the drainage device, but also more concave (see FIG. 3 '), may be flat or convex, and a cover 5 with handles 6, for example screwable on its circumference by means of a thread 4.
- the cover 5 has a circumferential bead 7 with a rounded inner surface 8.
- a core jacket 10 for example made of a low-abrasion plastic.
- the core jacket 10 has means for braking the bulk material, these means not being shown here, but in a parallel application (EP-A 0 225 417) by the same applicant.
- these means can consist of ribs running in the circumferential direction or radial ribs or wing-like, radial ribs or that the core jacket is of concave design and also that the side walls and the cover can also have a different shape.
- the core casing is held with play by a cylindrical center hub 11, which is hollow and also serves as a water inlet 12 or as an inlet for additives.
- the water inlet is connected to a rinse water connection 13 which is guided through the cover 5.
- a rinse water connection 13 which is guided through the cover 5.
- the core jacket is largely independent of the container and therefore does not vibrate or only dampens it to a great extent. Since the kernmantle lifts off the floor during rinsing, the rinsing water can escape from the bottom of the tank. Likewise, compressed air can also be conducted into the interior of the core jacket.
- the core jacket 10 allows the drain device 14 to be arranged in the middle of the bottom 3, that is to say under the core jacket.
- the adjustment of the locking pin 15 is not necessary as in the previously known example and can be carried out in such a way that even small and sensitive piece goods do not hit the transition point between the container bottom and the pin, thereby eliminating the risk of injury.
- the locking pin 15 is moved up and down by means of a schematically illustrated adjustment mechanism 16, whereby of course further adjustment mechanisms come into question and the locking pin can for example be tilted or retracted into the container bottom.
- the arrangement of the drain device in the bottom of the container enables simple and effective emptying of the bulk material. This makes it possible to collect and process the entire bulk material via a guide 17 in a mobile collecting device, during which the machine or its container can be quickly cleaned and loaded again.
- Such a container is suitable for the automatic loading and in particular automatic emptying of vibratory vibratory grinding machines and allows a significantly increased efficiency.
- the additives are not added via the water inlet, but rather via an opening 9 with a screw cap offset relative to the center.
- An overflow 18 is attached to the top of the container wall in order to drain off the foam formed during processing.
- the locking pin 19 is also actuated not from below or from the side, but from above.
- the center hub 20 consists of a first piece 21 in which the flushing water outlet 12 is arranged, followed by a tube 22 to which the closure 19 is attached.
- center hub with the water feedthrough can be arranged eccentrically, so that the core jacket can be displaced by rotation in such a way that the cross section of the grinding chamber can be changed.
- the drain device can also be arranged offset, in which case the base part is designed to be concave, convex or flat at this location and the core jacket is arranged above it, that is to say also offset.
