Device for residual free filling of powdery and / or granular material »

The invention relates to a device for filling dusty and / or granular material in sacks »in particular valve sacks in which the material to be filled is in the storage container loosened up with compressed air and made flowable undim Reservoir on at least during the filling process overpressure is maintained »

In the known valve sack fullims with a storage container that can be closed at the top, the filling material U ₀ a =, also »with compressed air, was filled into the valve sack , including porous parts were used _o Ss has also been proposed _for such porous plates not only in the horizontal plane but also obliquely anzuordnenπ could However, in these known filling machines have any rest loosely Füllgutaustragung be achieved ₀ in so-called Bruttoventilsackfüllmaschinenpbei which the filling

and weighing take place at the same time, this could not yet be done be accepted, the storage container with more filling material was loaded when the bag could be filled. residual material remained in most of the pills Above the waste outlet in the machine. In use of the already known type of machine as a net valve bag filling machine would be due to the compartment part already mentioned not possible, because that has already been done by a previous one Net bulk weigher, weighed product fed to the filling machine "vird" from where it has to be filled completely into the sack. If only small quantities remain in the filling machine, see above the weight of the filled sack is no longer correct.

The invention is now based on the object of a filling machine in which the preferably pre-weighed, finely divided * powdery and / or granular material can be completely filled into the sack.

The solution to the problem is “that in part of the A filter stone as the wall of the filling material traversing the path Reservoir or the supply line is used.

The inventive design of the filling machine safely achieved that no filling material remains in the filling machine ο With the net filling there is the possibility of maintaining the weight of the filled sack and With the so-called gross bag filling machines, the changeover of the filling machine to another product can be done more quickly, because it no longer needs to be cleaned of any product remaining in the machine.

In the drawings is an exemplary embodiment the invention d arge, and two ;? shows: Pig »1 a valve valve filling machine with a conical ventilation device,

Mach Figure 1 has the valve bag filling machine π one Storage container 12 at the lower end of which a porous Kegelituapf 13 is arranged, which the transition from the wide Cross section of the reservoir "12 to the narrow cross-section of the Line 14 for the filling nozzle 15 formed the feed line 14 is also a shut-off 16 available. "Around the porous truncated cone 13 a cylinder 17 is tightly arranged the supply line 18 air can be passed into the cylinder 17. In the upper part of the storage container 12 is a "shut-off device 19 and a feed 2o for Compressed air is arranged a vent valve 21 is also provided

In this filling machine, to fill a valve bag, the shut-off device 19 is first opened and at the same time air is fed into the cylinder through the air supply 18, which then results in good permeability of the filling material through the porous control stump 13. The shut-off valve 16 is still closed. The filling product is still closed so now gekoanen at <?. s reservoir 12 and when this process is complete _r is the shut-off geschlossen.Nun i9 again is gofUhrt through the air inlet point 2o compressed air, which builds up a positive pressure in the reservoir 12 has reached the overpressure the desired size, I open the shut-off device 16 and the product passes through the; Line 14 into the filling tube

Füllröiire kept the filling material capable of flowing 15 and from there to the In the bag 22 "vird In this process, passing through the perösen by the truncated cone 13 of finely divided air and flies.-st completely out of the ^ orratsbehäl Trer 12 in the line 14 from the LSI of the reservoir 12 emptied , the shut-off device 16 closes and at the same time the valve 21 opens to release the excess pressure in the storage container 12. Process initiated The filling material in the storage container 12 is weighed P beforehand by a pouring scale, whereby the balance can be coupled to the shut-off device 19. Due to the frustoconical design of the porous part 13, the filling material leaving the storage container 12 has no possibility whatsoever to settle, so that all of the previously weighed fill in the storage container amount of material from the storage container into the valve bag 2i! can flow away.

In the case of the one shown in FIG. Valve bag loading, drawing same places, the same parts in FIG vie In these machines, there is provided a slanting feed screw 23 on the reservoir 12, velche up in the.

Thereby an overpressure builds up in the reservoir 12 and passing through the porous wall 26 of compressed air keeps the filling material capable of flowing, whereby the worm 23 ift the filling material without loss through the filling nozzle 24 the bag can transport 25 ₃ Bs remains no! Residue in the storage container back, so that the bag 23 is filled with the previously weighed amount of filling material, If the filling material is discharged through the screw 23, the air admission is interrupted at 28 and 2o and the screw 23 is shut down. At the same time, the vent valve 21 is opened for a predetermined period of time After that a new AbftilIvorgang can be initiated 19 "by opening the shut-off - ■

FIG. 3 shows a section along the line III-III in FIG shown, from which it can be seen that the container wall 26 the screw 23 includes, so that as inclined surfaces of the lower End wall of the storage container 12 are formed by porous parts, which means that there is no material at this point can settle because the compressed air flowing through it tiles * capable is kept.

The advantage of this device is that no filling material is caked in the storage container or in the screw conveyor or can get stuck so that the already weighed product in the storage container is completely applied to the sack will be «weight differences between individual bags absolutely avoided.
