Definitions
- the invention relates to a method for adapting the volume of a collar sack which is not completely filled with bulk material, the collar of which is formed by two mutually opposite, outwardly bent first edge strips and two opposite, inwardly bent second edge strips to the bulk material volume located in the sack.
- the invention further relates to an apparatus for performing this method and a sack that can be used here.
- valve bags are the low dust discharge during filling and the good stackability / palletizability.
- a valve sack is often filled incompletely when filling with a bulk material with a fluctuating density if the bulk material density increases. The consequence of the incomplete filling of the sack is top air above the bulk material. Due to the trapped air, the contents of the sack appear spongy; Safe palletizing and handling of such sacks is not possible.
- the filling speed can be increased significantly compared to that of a valve sack; however, the dust leakage is significant unless special measures are taken. If an open sack with the for the largest possible filling volume required length is used, the bag is compressed after filling with a bulk material of greater density and a correspondingly smaller filling volume than intended per se over the bulk material and the bag length is reduced by cutting off the excess to the amount necessary for secure closing.
- the sack which is adapted to the filling volume in this way, is difficult to palletize, since it is flat at the bottom but generally wedge-shaped at the top.
- a collar bag or a method and a device for transporting, checking, filling and closing a collar bag is known.
- This sack combines the advantages of the open sack and the valve sack, because it is characterized by a large filling cross-section and the possibility of a dust-tight seal during the filling process. Due to the partial closure even before filling, this sack is designed for a certain, non-adjustable volume. If, therefore, the bulk density rises above the intended value, this sack will also only be filled incompletely. After closing, it can therefore have similar disadvantageous handling properties as the incompletely filled valve bag.
- the present invention has for its object to provide a method for adapting the volume of a filled collar bag to the bulk volume contained in the bag, so that handling disadvantages due to incomplete filling or a top air volume are avoided with this bag. Furthermore, a good durability of the closure should be achieved in spite of the volume reduction or reduction of the bag length.
- the advantages of the collar sack over the valve sack and the open sack are to be retained, ie a sack is to be created which, in addition to a large load filling cross-section and a dust-tight seal when filling also allows a reduction of the bag volume to the actually contained filling volume.
- a bag that can be easily palletized is to be created.
- a device for adapting the volume of a collar bag is also to be created, which can be integrated into a continuously operating filling system for collar bags.
- a new sack is to be created which can be handled well in the preparation for filling, in the filling itself and in the subsequent process stages, in particular when closing.
- This sack should be designed in such a way that it can be filled without dust escaping and the sealing surfaces of the sack (by gluing or welding) are not affected by layers of dust.
- the sack should therefore be easy to seal, preferably on a flat surface.
- a sack is to be created, the closure volume of which can be adapted to the actual filling volume.
- This object is achieved according to the invention in the method mentioned at the outset by pulling apart the first edge strips and thereby pulling the bag wall out of the upper empty bag part over the fold edges into the collar or through the bag cross section. Pressure on the opposing larger sack wall parts reduced.
- the first edge strips are accessed in general at these centrally on. It is preferably pulled apart at right angles to the central plane of the sack or to the sack wall connected to the first edge strip. Other trigger angles are also possible.
- the unfilled sack part which is therefore unnecessary for packaging, is reshaped into the sack collar, so that this gains in width what the sack loses in length .
- the free cross section of the Bag opening is reduced and the initially empty bag volume disappears. Due to the central attack on the first edge strips, the latter can generally be shortened with a corresponding extension of the second edge strips without being hampered by the attacking gripping elements.
- the first edge strips are generally pulled apart in opposite directions.
- the widened collar is used to form the closure, which is more resistant and stable than an un-widened collar.
- the folded edges move towards the bottom of the sack.
- the cross-section of the sack is reduced by pressing on its broad sides, the product level rises, as a result of which the upper air space disappears. This design requires that the contents flow freely so that the sack does not tear sideways.
- the sack bottom is raised at the same time as the first edge strips are pulled apart by the stretch of one of these edge strips.
- the sack wall is relieved of the sack weight. It is thus avoided that the first edge strips tear off or become damaged as a result of the bag weight.
- the first edge strips are pulled apart laterally.
- the direction of pull generally forms an angle between 70 and 110 °, in particular an angle of 90 °, with the central plane of the sack.
- the reshaping of the sack wall into sack collars requires a flexible sack wall / collar material. This material is preferably a multi-layer paper or a plastic film.
- the first and second edge strip parts lying one above the other in the four gussets are at least partially connected.
- the filled sack, shortened according to the invention is partially closed, since only the reduced opening remaining between the inner edges of the second sack strip remains to be closed.
- This connection of the superimposed edge strip parts is expediently carried out by thermal activation a hot melt adhesive applied to the top of the first edge strips. This activation can take place, for example, by lowering and pressing on a heating plate, by an infrared heater or the like. In the case of bags made of plastic film, this connection can be made by welding.
- edge strips are expediently glued for the purpose of closing the sack, and a cover sheet is placed on top. This cover sheet is used to close the remaining cross-section of the bag opening.
- the first edge strips are then folded or folded over, glued and again folded over and pressed on.
- a stable bag closure is thus formed from the pulled-apart bag collar within the scope defined by the bag cross-section.
- the reduction in cross-section of the sack is preferably achieved by exerting the pressure by progressively squeezing the sack. In this way, bulk material in the sack is displaced upwards without pressure being generated in the lower part of the sack, which may lead to the sack wall bursting. In contrast to the shortening of the sack by pulling the upper sack wall into the collar, this procedure requires a certain fluidity of the bulk material.
- the reduction in cross-section of the sack also levels out bulges on the large side walls, ie the sack shape approximates the cuboid shape, which makes the sack easier to stack and palletize.
- the pinching is preferably effected by means of a vertically progressing, horizontal pressing zone.
- a collar sack the collar of which is formed at the sack opening by two opposite first edge strips and two opposite second edge strips, of which the first edge strips are bent outwards and the second edge strips inwards (towards the opening), and the transitions from a first to a second edge strip are formed by double-layer gussets, the lower layers of which are connected to a first edge strip and the upper layers of which are connected to a second edge strip.
- the collar formed at the bag opening can of course have a different angular position to the bag walls.
- the collar can have different angular positions with respect to the sack body, in particular in the different stages of the filling process, which can also deviate from the horizontal position.
- the top of the collar is in one plane.
- the bag is sealed on the top of the bag collar during filling.
- the sack collar can be formed by simple kinks at the opening edge. It can be pre-formed by kinking, particularly in sack production, so that it can be easily set up in the course of the preparation and filling of the sack and can be carried out by appropriate mechanical guides.
- the two layers of the gusset are areally unconnected and can therefore be shifted against one another.
- the two layers of each gusset are preferably connected via common folded edges, the arrangement and lengths of which can be changed by tensile forces acting on the two first edge strips and directed away from the bag opening.
- the inner edges of the second edge strips approach, the blind opening being closed from its narrow sides except for a residual opening.
- the sack walls are over the fold edges pulled into the sack collar, whereby the sack loses length.
- the unconnected gusset layers are therefore a prerequisite for a sack that can be adapted to the actual filling volume.
- the tensile forces acting on the first edge strips and the flexibility of the bag wall material are necessary and sufficient for the displacement of the four gusseted fold edges.
- the two first edge strips at least partially have an activatable adhesive layer on the upper side.
- the two second edge strips expediently at least partially have an activatable adhesive layer on the underside.
- the two gusset layers are already releasably connected in manufacture.
- a displacement of the gusseted fold edges and the buckling edges and thus the shortening of the sack just described is generally not possible unless the connection of the gusset layers can be temporarily released by the aforementioned tensile stress and can be restored in a different arrangement after activation by activation of the sack.
- the activation is expediently carried out by the action of heat and possibly pressure.
- the collar bag according to the invention can consist of paper or plastic film.
- at least one of the first two edge strips is widened and the gaps between this edge strip and the upper layers of the connected gusset are sealed by sheets glued on.
- the leaves can also be attached in a different manner to the gaps in a manner corresponding to the bag wall material, for example by welding.
- the broadening of the first edge strip or strips can be achieved, for example, by a staggered cut of the multilayer sack material.
- One of the sack wall layers then protrudes over the other sack wall layer (s) and thereby creates the widening. This widening is necessary so that the gaps can be covered over their entire length and beyond by the sheet placed on them, and so that a complete gap closure is possible.
- the widened first edge strip, the upper layer of the adjacent gusset and the second edge strip are provided on the top with an adhesive track.
- This adhesive track can be activated, for example, by the action of heat or moisture, so that the collar forms a tight seal after the first edge strips have been correspondingly folded in.
- the sack closure can also take place by means of adhesive applied after filling or by ultrasonic welding.
- each gap will be sealed with a separate sheet. If only a first edge strip is widened, two sheets are therefore required to seal the two gaps; if the first edge strips are widened on both sides, a total of four sealing sheets are required to seal the gaps on all four gussets. Instead of the two separate sheets on a widened first edge strip, it is also possible to use a single long leaf which covers and seals the two gaps on the edge strip.
- the object is finally achieved according to the invention in the device mentioned at the outset in that a) the holding and transport means can be brought into and out of engagement with the first edge strips and gripping elements which can be moved transversely to the transport direction are provided on their outer sides, or b) below the holding and Transport means pressure body are arranged.
- the sack can be shortened to the actual filling level in the filling station following the filling with bulk material or preferably in a subsequent station before the closure is produced.
- the first edge strips of the sack collar must have a sufficient width so that they still offer a sufficient contact surface for the gripping elements on the outside of the holding and transport means.
- the holding and transport means release the first edge strips after. during or before the gripping elements have grasped these edge strips. The gripping elements then move apart and pull the excess bag wall into the collar.
- the opposing gripping elements move laterally, preferably perpendicularly, away from the central plane of the bag.
- the gripping elements can also be moved parallel to the central plane of the bag if corresponding devices are provided for the further deflection of the first edge strips.
- this sack shortening can be achieved by lifting the sack by the shortening distance by the grippers, especially with lower filling weights.
- a bag carrier is arranged vertically below the holding and transport means, which takes up the bag weight. The movements of the gripping elements and the bag carrier are synchronized and their strokes are essentially the same length.
- the lifting work is carried out by the bag carrier, while the gripping elements only do the (considerably less) deformation work on the bag wall material. This prevents the first marginal stripes take damage when pulling apart if bags with a higher filling weight are shortened in the manner according to the invention.
- the maximum stroke of a gripping element or the bag carrier is equal to half the length of the first edge strip of the bag collar; Through such a stroke, the bag opening is completely drawn through the second edge strips as if by a two-part curtain.
- the holding and transport means are preferably formed on each side of the sack by a pair of bands, which receives one of the first two edge strips between them.
- a band of the pair of bands preferably the upper band, can be moved vertically, so that the edge strip in the pair of bands can be clamped for the purpose of holding and transport or released for the purpose of shortening the sack by pulling the unnecessary sack wall into the collar.
- Other means of transport than pairs of belts running on one another can also be used for the bag transport.
- support rails extending in the transport direction are arranged on the inner sides of both holding and transport means. These rails not only offer a counter bearing when pressing the seal of the filler neck against the bag sleeve, but they also cause an exact deflection of the bag wall material in the collar when the bag is shortened.
- At least one fill level sensor is preferably provided, which provides a signal which is dependent on the actual fill level in the filled bag and which can be used to control the stroke of the gripping elements or the bag carrier.
- the pressure bodies are a pair of pressure elements which can be brought into engagement with the two bag wall parts and can be moved perpendicularly and parallel to the bag axis.
- the movability perpendicular to the sack axis enables an adjustable cross-sectional reduction of the sack, so that the empty volume initially present above the bulk level in the sack is filled by the rising bulk material.
- the horizontal mutual distance between the two pressure elements is therefore controlled by the height of the empty volume of the sack to be removed, this height being determined by a suitable sensor.
- the displaceability of the pressure elements parallel to the sack axis is necessary in order to displace the bulk material in the sack and to effect the progressive deformation of the sack as a whole.
- the pressure elements are expediently a pair of rotatably mounted rollers. As a result, the sliding friction of the elements on the sack wall is avoided and this is less stressed during the sack deformation.
- a heating device and / or a glue application device are expediently assigned to the device according to the invention.
- the hot-melt adhesive strips on the edge strips can be activated by the heating device and the gusset layers can be glued together.
- the glue application device enables the application of an adhesive for fastening a cover sheet and for producing the bag closure.
