Definitions
- the invention relates to a method and a device for opening prefabricated (tubular) pouch packs (“pouches”) and a method and a device for filling prefabricated (tubular) pouch packs, which includes a method and a device for opening such pouch packages.
- the opening of prefabricated, flat packaging pouches which are mostly rectangular and have a circumferential seal and an opening zone, takes place in that a pouch packaging or pouch is gripped with grippers on its two side edges adjacent to the opening zone will then move towards each other by a certain amount, so that the bag packaging is opened.
- This process is disadvantageous in two respects.
- opening a bag by moving the side edges together is only possible with relatively small dimensions, since otherwise the bag only bends without opening and, on the other hand, the bag is only opened to a relatively small degree due to the elasticity of the sealing seams, which leads to leads to a correspondingly low maximum filling quantity.
- the object of the present invention is therefore to provide a method and a device for opening prefabricated pouches with which the mentioned disadvantages are overcome and unlimitedly large bag packaging can be opened safely and in particular be opened much further than is the case with the prior art.
- this object is achieved by a method for opening prefabricated pouch packaging (“pouches”), each pouch packaging having a circumferential seal and an opening zone, with the steps: a) holding a pouch packaging on a carrier; b) introducing the Carrier with the pouch packaging in a vacuum chamber which has a first opening, which is opposite the opening zone of the pouch packaging and communicates with the environment, and a second opening facing away from the opening zone; c) suction of air from the vacuum chamber through the second Opening, with a volume flow that is sufficient to create a negative pressure in the vacuum chamber from the environment through which the bag package is opened; d) moving the carrier with the bag package held thereon out of the vacuum chamber.
- the bag packaging is preferably held on at least a first side edge.
- the bag packaging is expediently held displaceably on a side edge opposite the first side edge, so that the opening is not hindered.
- the carrier preferably has a bowl-like shape which corresponds on one side to a fully opened bag packaging.
- the vacuum chamber is formed on two separable half-shells which receive the carrier in between.
- the vacuum chamber is expediently essentially cylindrical.
- the first opening can be located in a first end face of the vacuum chamber.
- the second opening can be located in an end surface opposite the first end surface.
- the arrangement is preferably such that the opening pouch wraps up against the edge of the first opening and essentially closes it. It is thereby achieved that, due to the continuous suction of air through the second opening, an increasing negative pressure is built up, which largely expands the bag packaging against the elasticity or plastic deformability inherent in the sealing seams.
- the invention further relates to a method for filling prefabricated tubular pouches (“pouches”) in which the pouch packages are opened, filled and closed, the method being characterized by a method according to the invention for opening prefabricated pouch packages.
- the object of the invention is achieved by a device for opening prefabricated pouches (“pouches”), each pouch having a circumferential seal and an opening zone, with a) at least one carrier for holding a pouch, b) a vacuum chamber for receiving of the carrier, which has a first opening, which is opposite the opening zone of the pouch packaging and communicates with the surroundings, and a second opening which is remote from the opening zone, and c) a suction device which is connected to the second opening.
- the carrier preferably has a first, stationary clamping device for holding the pouch packaging stationary on a first side edge.
- the carrier expediently has a second, movable clamping device for movably holding the bag packaging on a second side edge.
- the carrier has a shell-like shape which corresponds on one side to a fully opened bag packaging.
- the vacuum chamber is expediently formed from a first and a second half-shell, which are separable from one another and accommodate the carrier in between.
- the vacuum chamber is expediently essentially cylindrical.
- the first opening can be located in a first end face of the vacuum chamber.
- the second opening can be located on a second face opposite the first face. The arrangement is preferably such that the opening pouch wraps up against the edge of the first opening and essentially closes it.
- At least one carrier and at least one first half-shell of the vacuum chamber are attached to a first rotating conveyor and at least one second half-shell to a second rotating conveyor, the first conveyor and the second conveyor running adjacent to each other within an opening area, so that a first half shell with a second half shell each form a vacuum chamber within the opening area.
- the invention further relates to a device for filling prefabricated bag packs, with a filling device for filling empty bag packs, a sealing device for closing the bag packs, a removal device for removing filled bag packs and a feed device for feeding empty bag packs, which are characterized by a device according to the invention Open pre-made bag packaging is distinguished.
- Fig. 1 shows a top view of a carrier attached to a conveyor with a bag package held thereon (when closed);
- FIG. 2 shows a view corresponding to FIG. 1, a two-part vacuum chamber enclosing the carrier
- Fig. 3 shows a view corresponding to Fig. 2 with the packaging bag now open;
- Fig. 4 shows a view corresponding to FigJ with the bag packaging opened
- FIG. 5 shows a schematic view of a filling and sealing system for bag packaging.
- the method according to the invention for opening prefabricated bag packaging is first explained with reference to FIGS.
- Fig. 1 shows a plan view of a carrier 1, which is attached to an edge 2, which can in particular be part of a rotating conveyor, wherein a large number of other identical carriers can be attached to the chain at a mutual distance.
- the carrier 1 is designed in cross-section or in plan view in the form of a shell or channel with two contact surfaces 3 and 4 located in one plane, a prefabricated bag of packaging 5, which is in a flat form, being provided with clamping or gripping devices (not shown) in FIG the contact surface 4 is held stationary and displaceable against the contact surface 3.
- the bag packaging 5 is rectangular in its simplest form and has an overall U-shaped seal that revolves around leaving an opening zone open, so that the bag packaging can be closed after opening and filling by sealing the opening zone.
- the bag packaging 5 is provided with a bottom fold, which enables filled bag packaging to be placed on a flat surface, for example a shelf.
- the material of the bag packaging can be plastic, metallized plastic, a composite of two or more paper, plastic and / or metal foils or the like in a known manner. his.
- Fig. 2 shows a vacuum chamber 8 which is arranged around the carrier 1 with the bag packaging held thereon.
- the vacuum chamber 8 expediently consists of (at least) two parts which grip around the carrier 1 like a shell.
- a division plane can be arranged essentially in the plane of the bag packaging 5, or perpendicular to it, i.e. essentially in the representation plane of FIG. 2.
- the substantially cylindrical vacuum chamber 8 has an opening 9 on its upper (above the representation level of FIG. 2) end face, the edge line of which essentially corresponds to the cross-sectional shape of the carrier 1, or on which Carrier 1 is seen from the opposite side of the bag packaging 5 is supplemented accordingly.
- Fig. 6 serves to further explain the vacuum chamber 8, which in this example consists of two vertically divided half-shells 12, 13, between which the carrier 1 for the (not shown) bag packaging is accommodated.
- FIG. 3 shows a view corresponding to FIG. 2, the bag packaging 5 being fully opened. It can be seen that the first, stationary side edge 7 of the packaging bag has kept its position unchanged, while the second side edge 6 has moved in the direction of the first side edge in order to compensate for the opening or expansion of the bag.
- the bag 5 has one full surface against the correspondingly shaped carrier 1 and, on the other hand, is, as can be seen from the perspective illustration according to FIG. 6, with its upper edge largely against the Edge of the first opening 9. 6, the two half-shells 12, 13 of the vacuum chamber 8 form a second opening 10 opposite the first opening 9.
- Fig. 4 finally shows a view corresponding to Fig. 1, wherein the two half-shells 12, 13 of the vacuum chamber 8 are removed or moved apart again and the bag package 5 assumes its open, expanded shape, supported by the holder of its two side edges 6, 7 the corresponding contact surfaces of the carrier 1.
- a vacuum source or suction device is connected to the lower, i.e. connected to the opening zone of the bag packaging or second opening 10. Due to the flow resistance of the air through the first opening 9 into the vacuum chamber, a slight vacuum is already formed in it, while an inflow corresponding to the suction takes place through the opening 9, i.e. hitting the (still) closed edge of the bag packaging in the area of the opening zone.
- the strong widening of the bag packing has the advantages that on the one hand a maximum capacity is achieved, ie that a given bag can be filled with a maximum filling quantity, and on the other hand that due to a certain plastic deformation in the sealing area, this widened shape for a time of itself is maintained, ie at least until the subsequent filling process.
- FIG. 6 shows a schematic plan view of a section of a system for opening, filling and closing (sealing) prefabricated bags, the opening process being carried out in the manner according to the invention.
- the system has a continuous conveying device 2, to which a multiplicity of carriers 1 are attached at regular intervals.
- the conveyor device 2 which rotates continuously in the direction of the arrow 15, receives, at an input station 16 in the direction of the arrow 17, prefabricated bag packs which can either come from a corresponding supply or directly from a bag manufacturing machine, whereupon they are sent to an opening station 18 be opened.
- the filled and closed bags are finally delivered to an output station 22 in the direction of arrow 23.
- the opening station 18 is designed in accordance with the invention in such a way that a vacuum chamber is formed around each individual bag packaging supplied over a certain running length.
- a second conveying device 24 is provided, which runs closely adjacent to the first conveying device 2 within the opening area, the direction of movement and speed of the areas lying against one another matching (arrow 25).
- the second conveyor 24 is at regular intervals with half-shells
- the conveying device 2 thus carries completely opened bag packs 5, which are each held on carriers 1.
- the method according to the invention and the device as indicated in FIG. 6 enable continuous processing of bag packs at high speed, the individual bags being opened quickly, reliably and as far as possible.
