Definitions

  • the invention relates to the field of conveying and packaging technology. It relates to an apparatus and a method for packaging of products according to the preamble of the respective independent claims.
  • WO 2005/118400 (corresponding US 7,757,461 ) describes a device for the foiling of isolated subsidized objects.
  • the articles are preferably flat products, for example printed products such as newspapers, brochures, books, etc., or stacks thereof. When such products are welded into films, the films are usually perforated and thereby gas permeable.
  • watertight and therefore also airtight packaging is required in order to protect the packaged products from, for example, environmental influences such as moisture. But then the problem arises that the package behaves like a slightly inflated cushion and thus more difficult to handle and, for example, poorly stackable.
  • DE 202 02 487 U1 DE 102 32 107 A1 and DE 100 15 628 A1 show the evacuation of food packaging. However, these are not suitable for production speeds as high as required in the production of printed products.
  • DE 10 2007 049 703 A1 describes a forming shoulder for forming a film tube.
  • a shoulder wall is provided with openings for sucking the sheet material against the shoulder wall.
  • the film lies close to the shoulder wall and runs wave- and wrinkle-free.
  • the apparatus for packaging products is formed from a web of packaging material to form a tube by a longitudinal connection device.
  • the tube is open with respect to a conveying direction of the packaging material in an area in front of the longitudinal connecting device and closed in a region after the longitudinal connecting device.
  • the device has a suction device, which leads in the area in front of the longitudinal connection device in the still open tube, and in the area after the longitudinal connection device has at least one suction through which gas, preferably air, from the area after the longitudinal connection device from the hose and through the Suction device is sucked.
  • a section of the suction channel interacts with the longitudinal connection device to form the longitudinal connection.
  • a boom leads into the tube and then extends in the conveying direction to the suction, wherein a portion of the suction element, which cooperates with the longitudinal connection device for forming the longitudinal connection, is arranged outside the tube.
  • the products may be stacked on top of each other, but they may also be stacked and staggered, e.g. in a tile-like sequence of products.
  • the products can also be arranged inside each other or partly inside each other, for example, by being inserted into one another.
  • the product or products which, whether individually, stacked or staggered, etc., are in the same bag of packaging material are referred to as the packaging unit.
  • Successive packaging units are thus separated from each other by transverse welds. It is also possible for a plurality of streams of packaging units to be fed parallel to one another in the conveying direction and conveyed into the hose. By means of one or more further longitudinal welding devices they can be separated from each other transversely to the conveying direction.
  • the tube is open or closed, in the context of the present application, it is meant that the tube is open or closed in its cross-section, ie along its circumference. If the outer sides or web sections of the web of the packaging material are merely placed on top of one another, ie not connected to one another, then the hose is still referred to as open. Are then these track sections connected to each other, eg by welding or gluing, the hose is called closed.
  • the tube can be divided by transverse welding into individual sections with products.
  • the connections of the packaging material produced by the longitudinal connection device and the transverse welding device are preferably gas-tight. Thanks to the suction device, there is little gas, especially air, in the resulting sections, and the products thus packaged are easier to handle and stack. For example, production speeds of more than 25,000 individually welded products per hour can be achieved.
  • the web of packaging material is typically initially flat and is fed from a roll and folded in a manner known per se in a hose forming device into a tube.
  • the two lateral sides - with respect to the conveying direction or longitudinal direction of the web seen - edges of the web guided or placed on each other.
  • a portion of the suction channel acts together with the longitudinal connection device for forming the longitudinal connection.
  • the suction channel has a double function, whereby the number of elements in the area of the tube formation and the closed tube is reduced and thus collisions with conveyed products are avoided.
  • a jib can also lead into the tube in the invention and subsequently extend as far as the suction opening in the conveying direction.
  • a region of the suction element, which with the Longitudinal connection device cooperates to form the longitudinal connection, is arranged outside the tube.
  • the parts of the suction device arranged in the tube of the packaging material or leading into the tube are preferably flat, preferably with a height of less than three cm or less than two cm. This means that these parts are not thicker than this height at any point.
  • the shape of the suction device is adapted to the packaging of flat products, in particular printed products, in a flattened tube.
  • the parts of the suction device arranged in the tube of the packaging material or leading into the tube are preferably at least partially hollow for passing the extracted gas. These parts thus themselves form the channels or lines for the suction of the gas. It eliminates the need for separate lines, which could hinder the movement of the film.
  • An optional pressing device for example, with pressure rollers primarily presses the film tube together and against the products, and thereby supports the extraction of air or a gas in general. It is preferably arranged directly after the suction section.
  • An optional pressing device is preferably provided for compressible, in particular compressible products, for example printed products such as newspapers. It presses the products to the conveyor, keeps the products flat and, if necessary, additionally compresses the products shortly before the transverse welding device so that even less gas is present in the closed individual packaging after transverse welding. When compressed, partially elastic products expand again after cross-welding, they are held together by the welded packaging.
  • the pressing device is preferably arranged directly after the pressing device or, if no pressing device is present, on the suction section.
  • the plant section for packaging the products is designed and arranged such that the conveying direction of the products and the packaging material is horizontal.
  • the speed of feeding the products is not limited to acceleration by gravity.
  • the longitudinal connection device is preferably a welding device, in particular a longitudinal welding element for longitudinal welding of thermoplastic Packaging material, in particular a plastic film.
  • the longitudinal connection device is an adhesive device.
  • the Schlauchtechnischs- and packaging device is suitable for packaging non-flat products, especially of foods that are available as general cargo.
  • the extracted from the packaging gas may be air, or a protective gas according to the nature of the packaged products.
  • the packaging material is not gas-tight, for example by being perforated. Although this allows a certain amount of gas to flow in, there is a contraction of the evacuated packaging material Instead and higher production speeds than without suction can be realized.
  • the evacuated packaging increases friction between the products.
  • the products are better fixed in the packaging and also allow a higher production speed.
  • the volume flow of the suction device is adjustable.
  • it can be adjusted according to the production speed, or reduced, for example, when using sensitive packaging materials.
  • damping rollers which are inherently resilient, preferably elastic and damping, and the longitudinal welding device and / or the transverse welding device with respect to the tube of packaging material with products are opposite , wherein welding elements such as welding bars when welding through the hose and possibly also by a conveyor, such as a conveyor belt exert a force against the damping rollers, wherein by the damping rollers a deflection of the hose with the products and optionally also the conveyor belt is damped.
  • a transverse welding device has damping rollers as described above.
  • a tube is formed from a web of packaging material, wherein the tube, with respect to a conveying direction of the packaging material, is open in a region in front of a longitudinal connecting device and is closed in a region after the longitudinal connecting device.
  • a suction device in the area in front of the longitudinal connection device leads into the tube which is still open along its circumference and has at least one suction opening in the region downstream of the longitudinal connection device, with which the suction device sucks gas out of the tube after the longitudinal connection device.
  • a section of the suction channel interacts with the longitudinal connection device to form the longitudinal connection.
  • a boom leads into the hose and then extends in the conveying direction to the suction, wherein a region of the suction element, which is arranged outside the hose, cooperating with the longitudinal connection device for forming the longitudinal connection.
  • FIG. 1 shows an overview and FIG. 2 a side view of a plant section with a hose forming device 1, a longitudinal welding device with suction device 10.
  • a film 20 passes through the plant section in the arrow direction. It is fed as a film web and folded into a tube, thereby embraces a stream of isolated, present as piece goods 24 products, is welded in the longitudinal direction, ie in the conveying direction, and then welded in the transverse direction between the products 24.
  • gas typically air
  • a subsequently arranged transverse welding device 8 forms closed, generally gas-tight sections of the film tube. These are separated either in transverse welding itself or later in each other individually packaged products.
  • a pressing device for example, with pressure rollers 6 from
  • Foam present, and / or a pressing device for example with a press belt 7, which by means of weight and / or spring force, the hose with the products 24 therein holds down and optionally also compresses.
  • the pressing device and pressing device are preferably then arranged on the suction section 5, but not necessarily immediately thereafter.
  • damping rollers 83 are arranged in the region of the transverse welding device. They support a conveyor belt with products 24 transported thereon against a force which the transverse welding device 8 exerts on the hose 24 with the products 24.
  • the transverse welding device 8 has welding bars 81 with hold-downs 82.
  • the hold-down 82 stabilize the film webs respectively the hose during the welding process. In this case, the welding bar 81 and the hold-down 82 press against the hose and the conveyor belt.
  • the conveyor belt moves against the damping rollers 83, whereby the movement of the conveyor belt and the hose with the products is damped by the damping rollers 83.
  • damping rollers 91 of the longitudinal welding device can be arranged.
  • FIG. 3 shows a suction device 10 in a partially exploded view.
  • the suction device 10 itself has a suction element 11, which is connected to a connecting piece 16 via a suction line 17 to a (not shown) suction pump.
  • the suction element 11 is preferably designed substantially flat and has a boom 15 and a suction channel 13.
  • the suction channel 13 terminates in a suction opening 12.
  • the suction channel 13 has a Welding region 14, which cooperates with a longitudinal welding device, in particular a longitudinal welding bracket 9 for longitudinal welding of the film 20.
  • the welding region 14 may be a depression in the suction channel 13 or an opening passing through the suction channel 13.
  • the film 20 is folded longitudinally into a tube, the product 24 being conveyed onto the film 20 and into the tube.
  • the products 24 are thus covered on their upper side approximately in the middle of the flat-laid hose by a first edge portion or web portion 21 and a second edge portion or web portion 22 of the film 20 and are the product 24 on a third web portion 23rd
  • the first web section 21 lies above the second web section 22.
  • the inside of the first web section 21 rests on the outside of the second web section 22 Outside laid and then connected.
  • the film tube with the products 24 is then, subsequently to the tube forming device 1, conveyed in the conveying direction by an insertion section 2, a joining section 3, a connecting section 4 and a suction section 5 of the device.
  • the first track section 21 extends above and the second track section 22 below the boom 15.
  • the boom 15 of the suction element 11 thus leads into the still open tube.
  • the second web section 22 is directed upwards or, with respect to the hose, outwards and against the first web section 21.
  • the second track section 22 thus comes into contact with the first track section 21.
  • the tube is thereby closed, but not yet welded.
  • the boom 15 extends along the conveying direction.
  • the length of the merging section 3 depends on the conveying speed and the robustness and flexibility of the film material.
  • the first track section 21 and the second track section 22 are both above or, with respect to the hose, outside the suction channel 13 of the suction element 11, and are in contact with each other.
  • the suction channel 13 is thus located entirely within the tube.
  • a region of the suction channel 13 this is designed as a welding region 14.
  • the welding region 14 is a depression or a through opening in the suction channel 13, into which mutually lying layers of the packaging material can be pressed through the longitudinal connecting device or the longitudinal welding strap 9.
  • the longitudinal welding bar 9 presses the two above and outside of the suction channel 13 current first and second web portions 21, 22 a little into the welding area 14, which gives a necessary counterforce against the longitudinal welding bar 9, and welded together.
  • the longitudinal welding bar 9 preferably performs a weighing movement, as in the FIG. 4 indicated by a double arrow.
  • the suction channel 13 extends in width over at least a quarter or half or three quarters of the width of the flattened film tube in order to evacuate this as effectively as possible.
  • the evacuation or suction of gas thus takes place - in the widest possible range of the film tube - in the suction section 5, in which the film is welded in the longitudinal direction to a closed tube.
  • the suction opening 12 is open in the direction of the conveying direction, so sucked in the operation of the device gas counter to the conveying direction of the hose.
