Sweden i-Sver i ge (SE) (74) Oy Kolster Ab (54) Device for filling single- or multi-walled packages -

This invention relates to a device for filling single- or multi-walled packages, e.g. sacks (bags), bags, etc. The present invention relates to a device for filling single- or multi-walled packages, e.g.

Recently, there has been an increase in the handling of bulk materials, e.g. pellets, granules, powders, etc., in large bags of the single or multi-wall type, and thus the problem of handling large bags has come to the fore. Especially when filling and emptying big bags, work environment problems become major. This is particularly evident when dealing with powdered substances with a small grain size in multi-purpose or return bags, as the risk of inhalation of powder particles is particularly high in this context. In addition to work environment problems, it has proven difficult to fill large bags to their full volume without forming folds. The object of the invention is to develop a device which, without serious problems in the working environment, makes it possible to fill packages, in particular big bags, completely and quickly.

I _ 2 67340

Po. according to the invention said technical problem is solved and said object is achieved in that the nozzle has a conical mouth part which can co-operate with a suitable conical inlet part of the outer means and that the nozzle and / or outer means can be raised and lowered to press the package by sealing between the conical parts against the nozzle and on the other hand to gradually release the package as it fills.

The invention makes it possible to fill different types of big bags tightly without creasing and without the release of particles dangerous to the working environment into the air at the workplace.

Figure 1 shows a schematic side view po. an embodiment of the device according to the invention; Fig. 2 shows a schematic side view of the embodiment of Fig. 1 during filling of a large bag; Fig. 3 is a schematic top view of the embodiment of Fig. 1, with certain parts omitted for clarity.

Po. an embodiment of the invention will now be described with reference to the drawings. The device consists of a nozzle 1 and an outer funnel 2. The nozzle 1 has a conical mouth part 3 which circumferentially surrounds the nozzle tube 4. The nozzle tube 4 contains an adjusting means in the form of a damper 5 and can be connected (not shown). The conical mouth part 3 is provided at the top with a roof 7 which closes tightly around the nozzle tube 4. A fluid inlet pipe 8 and an outlet pipe 9 are placed in the ceiling 7. The fluid can be, for example, air. The inlet pipe 8 has a control damper 10 and the outlet pipe 9 has a control damper 11. When the fluid is air, the inlet pipe 8 can be connected to a standard fan or to an existing ventilation system. Outside the conical mouth part 3, means can be placed which reduce friction and seal, or only a seal, e.g. a rubbery substance.

The outer funnel 2 has a conical inlet part 12 into which the conical mouth part 3 fits. The inlet part 12 can be provided on the inside with means for reducing friction and a seal or only a seal, e.g. a rubber-like substance. The conical inlet part 12 becomes a tubular outlet part 13 and lifting members 14 are arranged at the 67340 transition point between the two parts 12, 13. To these lifting element webs 14 are attached ropes 15 and 16 which can be wound on rollers 17 and 18 fixed to the same shaft 19, connected to the actuator 20.

Figure 2 shows in more detail how the disposable type big bag 21 is filled po. with a device according to the invention. The large bag 21 has an inner part and an outer part, and the inner part is pulled up into the outer funnel 2 so that the mouth part 3 and the nozzle tube 4 can be introduced into the inner part. This becomes pressed against the mouth part 3 by sealing, because the outer funnel 2 is lifted by means of ropes 15,16. The fluid, mainly air, is then fed into the interior through the inlet pipe 8 and the damper 10, and in this way the interior of the large bag 21 is inflated completely and its wall is made smooth. The introduced air is discharged through the outlet pipe 9 through this damper 11. When the inner part is completely blown, the introduction of the substance can be started by opening the damper 5.

When the inner part of the big bag 21 is partially filled, the damper 5 is closed and the outer funnel 2 is lowered by means of ropes 15 and 16, after which the inner part of the big sack 21 is allowed to slide between the funnel 2 and the nozzle 1, after which the procedure is repeated. This avoids the formation of wrinkles. During filling, the large bag 21 may be located on a lifting and lowering platform or it may be held upright by means of a fork-lift truck or the like.

Instead of raising and lowering the outer hopper 2, the hopper 2 can be fixed and the nozzle 1 can be raised and lowered by means of a device which is in principle similar to that described for the hopper 2.

If the nozzle tube 4 is filled with material by means of a feed screw, this must be stopped with the damper 5 open and vice versa.

Claims (4)

67340 A device for filling single- or multi-walled packages (21), e.g. sacks (bags), bags, etc., wherein the nozzle (1) can be inserted into the package (21) and the outer means (2) is adapted to press the package (21) sealing against a nozzle (1) having one fluid inlet (4), at least one fluid inlet (8) and at least one fluid outlet (9) for feeding fluid into and out of the package (21) to straighten the wall of the package, characterized in that the nozzle (1) has a conical mouth part (3) which can co-operate with a suitable conical inlet part (12) of the outer means (2), and that the nozzle (1) and / or the outer means (2) can be raised and lowering relative to each other, on the one hand, to press the package (21) by sealing between the conical parts (3, 12) against the nozzle (1) and, on the other hand, to gradually release the package (21) as it fills. Device according to Claim 1, characterized in that the fluid inlet point (8) and / or the fluid outlet point (9) are provided with means (10, 11) for controlling the fluid inlet and the fluid outlet.
