Method for filling granular material and a filling device therefor

The invention relates to a method for filling granular material and a filling device for this purpose.

The filling of granular material into containers was determined Vo'umens requires complicated metering devices, probably are available in manufacturing plants, but not with the consumer, who has large transport containers in handy needs would like to transfer a container for direct consumption.

The usual procedure is dit. · Using funnels that be inserted into the filling openings of the container to be filled and then use a scoop to add the granular Material from egg-sized Ί inspor t containers into the supply container is transferred. The dosage is developed via the

Weight determination using a scale or, if there is Transport container has markings by pulling according to volume. In any case, direct visual control is necessary. This is time consuming and depends on the concentration of the staff.

A known automatic bag filling scale has a Vibrating chute through which the product enters the inlet mechanism which feeds it to the load vessel of the Waaqe - the l'.ufluß is locked after reaching the target weight ;. Thereon the container empties its contents into the filling funnel which the material flows into the bag. This facility is for transferring from large containers to the consumer expensive, both in terms of technology and resulting from it, in terms of economic use. (Greif-Werk Lübeck, 291 / 3.68)

Another known filling device has a volumetric metering device in the form of a metering screw. The dosing screw is mounted on a vibrating tube so that the outlet tube and the screw bearings vibrate while the The screw rotates at the same time. The vibration of the dosing screw is supposed to cause blockages, pressure build-up and flooding prevent the bulk material. The dosing is controlled with the speed of the screw. The same applies here with regard to this Usability of this system for the consumer is what was said above about the balance principle. It's because of the effort involved in bottling Not very suitable for consumers. (Simon Handling Eng. Ltd. Stockport, GB)

The invention h <\\: the AuIq ibi ¹ , <-> in I ·; i η I ül 1 before f> ihivn and d.>: -. u to specify a filling device with which the consumer can transfer granular material from the transport container to the required container with sufficient volume accuracy. The device should be easy to transport, simple in construction and safe to use.

The method according to the invention is that the granular material when filling up to the lower edge of the need sbehäl ter introduced filling pipe flows in and the filling of the empty space, which is through the 3edarfsbehält towards and formed by the bulk surface determined by the angle of repose of the granular material up to the lower edge of the filling pipe is done with the granular material from the filling tube end below the closed slide gate. The one with this Solution achieved advantages are above all that the metering in the simplest way solely through the lower edge of the introduced filling tube is achieved. The granular material flows to the lower edge of this filling pipe, from where it falls with the angle of repose down to the outer walls of the supply container. The angle of repose is known by the physical Constants of the granular material such as density, friction and load are determined. This is the lead-in length of the Filling tube the measure for the filling volume. After closing the slide valve still remaining below in the filling tube Amount of the granular material continues to flow when the supply container is removed. In any case, this is a constant amount, which is automatically taken into account when determining the volume.

The filling for you ^v rhführunq dos process b <\ s | -eht from one to the filling opening of the Transportbohä]. tcrs connected and adjustable in the insertion length filling tube with a locking slide. This very simple Vorrichtunq meets all the requirements of the task, it is easy to transport, simple in construction and safe to use. DOMiT enabling all consumers jhm ¹ difficulties and further costs the transfer of the granular material; from large transport containers to supply containers. To do this, the filling device is placed on the filling opening of the large container, e.g. 3. fixed by screwing on. Then the container is turned through 180 and the end of the filling tube is inserted into the opening of the container. After opening the locking slide, the granular material flows automatically up to the lower edge of the filling tube into the demand container and then after locking the amount remaining below the locking slide in the filling tube end. The transfer process is finished.

In the embodiment of the filling device, the filling quantity is controlled by a lockable stop that can be displaced on the end of the filling tube certainly. With the position of this stop on the end of the filling tube, the filling volume is advantageously simple of the demand tank adjustable. This applies to filling for all containers with the same dimensions.

In a further configuration, the locking slide is actuated to open with a push button, locked it is restored by a compression spring that is tensioned in the process. This

The slide gate used here is known to function simply and safely in its design. Developed also flawless with this dosing device.

To the filling device even with not easy flowing granular Use materials in the same simple way l * u it is enough to fill the tube with a well-known vibrator equip.

A further simplification of the transfer process, especially when used with large transport containers and in a short time consecutive decanting in demand containers, it arises when in further training the In accordance with the invention, the filling device has a holding device connected to the filling pipe that can be suspended in a suitable wall rail or the like owns. Thus, the transport container can be in permanent readiness for after hanging the filling device Keep filling. It can be tapped at any time.

An embodiment of the invention is shown in the drawing and is described in more detail below:

The filling device 1 is fastened to the filling opening of the transport container 3 with the aid of the union nut 2. This is filled with the granular material 18 to be filled into the small container 4 required. After the filling device 1 has been attached, the 'j'ransportbe.häl ter 3 is rotated by 180 and both parts are then connected to the holding device h which forms one piece with the filling pipe 5

hung in the wall rail 7. The wall rail 7 is attached to the wall 8. The filling tube 5 contains the slide valve 9, the slide 10 of which releases the inner cross-section 12 of the filling tube 5 by pressing the push button 11. Beirr Pushing in the push button 11 tensions the compression spring 13, which the slide 10 after releasing the push button 11 brings it back into the closed position 14. The fill 1 rohrf-uie Iu has a .verschiobba>: pü, rust at its lower ■ straight end adjustable stop 15 with which the insertion length of the F-'ii 1 1 ■■ o'.rendes 16 is adjustable. The filling tube end 16 will stop until r.uin 15 introduced into the formation 17 of the requirement container 4.

After opening the locking slide 9, the granular material 18 flows into the demand container 4. The material flow stops when the level in the demand tank 4 with his upper tip reaches the lower edge 19 of the filling tube 5. The demand container 4 is then from the lower edge 19 with the angle of repose 20 of the granular material 18 up to the demand tank walls filled. After the locking slide has closed automatically 9 flows when the need container is removed: granular material 18 from the filling tube end 16 up to the closure slide 9 in addition to the demand container 4 and fills the space 21.

Each further filling of demand containers 4 repeats the filling process precisely. Exact dosing is guaranteed.
