Definitions

the invention relates to a trickle protection device for a filling station for filling containers with a Bulk material, which has a filling pipe, over which the Bulk material gets into the container.
Containers such as sacks or so-called big Bags, barrels or containers are usually in a special Filling station designed for this purpose is filled with a bulk material.
the filling station has a filling pipe that the bulk material gets into the container.
shut-off devices are usually used provided the filling tube during a change of containers close to prevent the bulk material from trickling down.
the conventional shut-off devices are however so trained that they in the open state, that is, during filling a container with the flow of the bulk material come into contact that parts of the shut-off devices too be contaminated on the surfaces with bulk material in the closed Show condition to the outside. Of these areas can therefore still pour bulk parts and into the environment arrive so that with the conventional shut-off devices a completely clean finish to the outside cannot be achieved is.
the object underlying the invention is therefore therein, a trickle protection device of the aforementioned To create a way with a clean end of the filling pipe to the outside when changing containers.
This object is achieved according to the invention by a two-part Flap with a dimension at least equal to the dimension of the filling pipe inner cross-section solved, which cross in Filling tube is arranged and its flap parts around a shaft each foldable in the direction of the bulk material flow are.
the flap parts are folded up during the filling process and remove the valve parts before removing the filled container unfolded from the filling tube so that the filling pipe is closed to the outside. Because the surfaces the flaps, which point outwards when closed, are those who are in the open state during the Filling the flap parts in the folded state lay against each other so that they could not be contaminated, is contamination by bulk material parts attached to these Stick surfaces, excluded. This makes one perfect achieved a clean finish to the environment, which is an optimal Personal protection guaranteed when filling bulk goods, the the maximum workplace contamination values MAK falls below that specified by the legislator.
the filling station shown in Figure 1 has a filling tube 1, over which a bulk material in a container 2, such as for example a bag or sack.
a trickle of the bulk material when changing containers to avoid where there is no container for a short time at the filler neck of the filling pipe is a trickle protection device preferably at the lower end 3 of the filling pipe 1 provided that during the change of containers Can complete filling tube 1 to the outside.
FIGs 2, 3 and 4 is the basic structure of the trickle protection device and their closed and open ones Position shown in each case.
the trickle protection device comprises a two-part Flap with flap parts 4 and 5, which are attached to a shaft 6 are, which sits in an annular holder 7, the is attached to the lower end of the filling pipe 1, or directly attached to the filling pipe 1 or inside the filling pipe 1 is arranged adjacent.
the two-part flap has one Dimension that is at least the filling pipe inner cross section corresponds so that they are in the closed state, that in Figure 2 and shown in Figure 3, the interior of the Filling tube 1 can completely close to the outside.
the two flap parts 4 and 5 of the two-part flap are pivotable about the shaft 6 and into that shown in Figure 4 Position, that is in the direction of the bulk material flow and thus at the pouring station shown in Figure 1 can be folded down or forward.
Figure 4 is shown in detail, lie in the collapsed Condition both flap parts 4 and 5 with one of their outer surfaces together.
the trickle protection device is open, i.e. with their flap parts 4 and 5 arranged in the folded state, which is shown in Figure 4. If the package is filled, only the surfaces of flap parts 4 and 5 come in contact with the bulk material, which in the closed state, which is shown in Figure 3, inwards into the filling tube are directed. The surfaces of the flaps 4 and 5, which are closed State directed outwards come with the Bulk does not come into contact when filling.
the trickle protection device Shortly before a filled container is removed from the filling tube 1 the trickle protection device is closed, that is, the flap parts 4 and 5 around the shaft 6 in a position pivoted transversely to the filling pipe 1, which is shown in FIG is shown. In this state, the filling pipe 1 is complete closed to the outside so that no bulk material can trickle, which is especially true when the trickle protection device at the extreme end of the filling pipe is appropriate. Those facing outwards when closed Surfaces of flaps 4 and 5 are clean since they are in use did not come into contact with bulk goods during the filling process were.
the trickle protection device After changing the container, if a new container to the Filling tube is connected, the trickle protection device opened again so that the new container can be filled can.
a part-turn actuator especially a double piston actuator 8, 9 provided for each flap part 4, 5, to pivot it around the shaft 6.
this is the Shaft composed of three individual parts 10, 11, of which the two outer 11 are connected to a flap part 5, while the inner shaft part 10 with the other flap part 4 connected is.
the drives 8 and 9 are at takeover points 12, 13 each with the outer shaft parts 11 and the inner Shaft part 10 in connection, which are shown in Figure 7.
the shaft 6 can also be formed in two parts, each Flap part 4.5 is connected to a shaft part.
the driving points 12, 13 for the outer and inner shaft parts 10, 11 are preferably as grooves designed to which the drives 8, 9 are coupled, as shown in detail in Figure 7.
FIGS. 8, 9 and 10 show an embodiment of the drive device, the contrary to the training that was described above, formed inside the filling tube is.
two are pneumatic or hydraulically actuated cylinders 14, 15 are provided, which have levers 16, 17 move the two flap parts 4 and 5 around the shaft 6.
the cylinders 14, 15 are on one or both sides in the filling pipe mountable.
the trickle protection device in particular at the lowest end the filling tube can be arranged without being on the filling tube external parts collided.
FIG. 11 finally shows a third embodiment of the Drive device for the trickle protection device, the without external drive components.
the drive device recorded and designed as a pneumatic rotary drive.
shaft 6 is a hollow shaft with various Designed chambers that are pneumatic or connections 19 be hydraulically loaded.
