Definitions

  • the invention relates to a method for creating a transport packaging from a container holding the goods and a fastening strip wrapping around the container and the goods, in which the goods are introduced into the container and the fastening strip is wrapped around the container with the goods.
  • the invention shows a device for carrying out the method, which works with a conveyor for the unit comprising the container and the goods and a fastening strip located on a roll.
  • two parts serve, one of which is in the Bottom area of the goods and the other is arranged in the lid area of the goods.
  • the two parts usually do not touch each other.
  • a bottom tray and a lid tray also of identical design, can be used and wrapped around by the fastening strip. This applies in particular to trays that have a side wall; but also an insert sheet, a lid or the like can form one or both parts of the container.
  • a transport packaging comprising a container holding the goods and a fastening strip wrapping around the container and the goods is known.
  • a one-piece tray which is arranged in the base area, is used as the container.
  • the fastening strip is formed by a shrink film that is open on the front.
  • the shrink film wraps around the goods and the tray.
  • the tray can consist of corrugated cardboard, film or the like.
  • a shrinking apparatus is required to create such transport packaging. The shrink film exerts more or less all-round pressure on the enclosed goods.
  • Streifbandzeitung is known as a form of dispatch for newspapers, in which the newspaper is folded up and surrounded by a paper banderole. This band is wrapped and glued as a fastening strip around the goods, namely the newspaper. The sleeve does not exert any appreciable pressure on the goods because it is loosely held around the newspaper without pre-tensioning. It is similar z. B. with boxes of chocolates, which are wrapped in a transparent strip of plastic film. The fastening strip from this film is suitable, but loosely and without pretensioning around the chocolate box, the ends of the fastening strip being connected to one another.
  • Banding machines are also known in which a continuous, cyclically driven conveyor is provided.
  • a roll with banding material is provided above and below the conveyor track.
  • Half-length banding strips are pulled off the rolls and put together, for example welded, in front of and behind the container holding the goods.
  • a tensile stress is applied to the two-part fastening strip.
  • the fastening strip is closed to form a band while the container is at a standstill. Due to the cyclical operation of the conveyor, the performance of such a banding machine is fundamentally limited.
  • the invention is based on the problems presented. It is the object of the invention to provide a method and a device of the type described at the outset with which it is possible to create a transport packaging even in the case of comparatively tall, slim goods, in which the goods are vertically received between two parts of the container under tension and by the fastening strip are held. This is intended to produce a transport packaging in which the fastening strip contains only one connection point, the two ends or end regions of the fastening strip overlapping at this connection point.
  • the method is intended to be applicable with continuous flow of the containers with the goods and lead to transport packaging which is advantageously manageable.
  • this is achieved in the method of the type described in the introduction in that the fastening strip is pulled off a single roll, looped around the unit of container and goods, cut to length and brought under tension, and then, while maintaining the tension, one end of the Gluing strip is glued and pressed on the other end until the glue sets.
  • the invention is based on the idea of using only a single strip of material, which is wound on a single roll, and dividing fastening strips from this, the two ends of which are connected to one another in an overlapping manner, so that only one connection point on the fastening strip or the one formed Banderole is available.
  • Such an overlap which extends over a certain distance, which is considerably longer than when welding two strips of plastic film, is advantageous in many respects.
  • the length of the overlap enables the container with the goods to be conveyed continuously while the fastening strip is being applied and while the glue is curing.
  • the transport packaging can easily be used as a single material packaging be formed because both the parts of the container and the fastening strips made of cardboard, paper, corrugated cardboard and. Like. Can be formed. This allows the container as well as the fastening strips to be recycled well together without the need for separation. If the container is relatively small, e.g. B. is designed as a tray, there is also a low material requirement. In addition, the container can be reused directly, for example for the return of empty reusable bottles.
  • the transport packaging enables good storage. The stackability is given.
  • the transport packaging can be handled in a simple manner. It can also be easily opened without special tools by cutting through the fastening strip. Damage to the packaged goods is practically impossible.
  • the application of the tension on the band strip is possible in a particularly advantageous manner because it is ensured that the container with its parts and the enclosed goods are conveyed in a rectangular arrangement relative to one another, so that a parallelogram-like shift is avoided.
  • the fastening strip is thus simultaneously placed around the container in such a position in which the tensile stress can be applied effectively.
  • the tensile stress that can be applied is surprisingly comparatively higher than in the prior art.
  • the fastening strip is pulled through the path of the unit in front of the unit of container and goods arriving on a conveyor and moved back behind the unit.
  • the tensile stress is introduced and held at the ends of the fastening strip to be connected to one another.
  • the front end of the fastening strip is placed on the unit and the rear end is glued and pressed onto the front end. All of this is possible while continuously promoting the unity of container and goods.
  • a cycle-wise work, as is known in the prior art, is thus avoided and so far performance increased significantly.
  • both parts of the container are conveyed vertically one above the other during the wrapping and the fastening strip is brought under tension.
  • the synchronous conveyance is continued at least until the glue has set on the fastening strip.
  • the fastening strip has the shortest length in this position of the parts of the container, the tensile stress can be applied very effectively. It is harmless if the synchronous conveying also takes place while the ends of the fastening strip are pressed against one another over the setting time of the glue.
  • the tensile stress is applied essentially over one of the ends of the fastening strip.
  • the front end is held in place, and in the area of the rear end the tensile stress results from the synchronous relative movement.
  • the process could also be carried out step-by-step. However, a continuous forward movement or promotion of the unit consisting of the container and the goods appears to be more advantageous.
  • the lid tray is pressed transversely to the conveying direction during its synchronous conveying.
  • the required forces are transferred to the lid tray via this pressure. If a cover tray with side walls is used, the force can be transmitted to a pair of parallel side walls and / or to the top of the cover tray.
  • the fastening strip is formed into a loose loop by swiveling its front end twice through the path of the unit, which loop extends around the unit Containers and goods stretch around.
  • the rear end of the mounting strip is held in place and the front end is tightened until the mounting strip contacts the front and rear walls and the bottom of the unit. This is the case if the roll of the fastening strip is arranged above the path of the conveyor.
  • the overlapping ends or end regions of the fastening strip are then connected to one another in the region of the cover or the cover tray, so that this connection point is easily and readily accessible for opening the fastening strip.
  • the single roll with the banding material below the web and to this extent form the connection point of the fastening strip in the region of the bottom of the container. It is important that the unit with its front wall penetrates a section of the fastening strip that is held in a stretched manner during its continuous conveyance, and that the fastening strip is thereby tensioned. While the pretension is applied by holding the rear end and tensioning the front end of the fastening strip when the loose loop is pulled smooth, the continuously conveyed unit of container and goods runs through a stretched, for example vertically held section of the fastening strip, so that when it is passed through Vertical tension uses a retightening effect because the rear end of the fastening strip is held in place.
  • the front and rear ends of the fastening strip are pressed onto the cover of the unit while maintaining the tension, the front end is pressed onto the cover and the rear end, after the gluing, is overlapped and pressed onto the front end until the glue sets. All of this takes place during the continuous promotion of the unit from container and goods.
  • the rear end of the fastening strip is braked and pulled off during the continuous conveying of the unit. The holding force applied by the brake is gradually reduced by pressing on the at the rear end of the fastening strip in the area of the cover of the unit, so that there is no risk that the pretension and the post-tension will decrease or be released.
  • a device suitable for carrying out the method works with a conveyor for the unit comprising the container and the goods and a fastening strip located on a roll.
  • the device is characterized according to the invention in that a pair of rollers, a brake, a device for severing the fastening strip and a gluing station having a pull-off device for the single fastening strip from the roller and a pair of pinch rollers arranged on a driven rocker are provided, the pinch roller pair in a takeover position for the front end of the fastening strip can be pivoted in by the pull-off device and is arranged so as to be pivotable by crossing the conveyor track twice to put the fastening strip around the unit comprising the container and the goods.
  • the conveyor is divided to cross its path, and an additional conveyor and a control device are provided for a synchronous movement of the two conveyors.
  • a roller carrier driven relative to the conveyor track is provided and for the pressing of the rear end a stationary roller conveyor is provided.
  • a single extraction device Since only a single fastening strip is used, only a single extraction device has to be provided.
  • This preferably has a pair of pull-off rollers and a pair of guide rollers, with the aid of which the fastening strip is pulled off or re-conveyed from the roller.
  • a brake and a device for severing the fastening strip are also provided.
  • the device for severing the fastening strip is used for cutting to length.
  • the brake serves to hold the fastening strip in place during the application of the pre-tension and the post-tension. Below the pairs of rollers and the brake there is a gluing station, in the area of which the fastening strip is held and the glue is sprayed on.

  • Different lengths of the fastening strip can be realized through different angular end positions. It is also possible to end the tightening of the loop formed around the container with the goods on the rocker when different angular positions are reached, in order to adjust the length of the fastening strip to the circumferential length of the container.
  • the conveyor for the bottom tray can in particular consist of a chain conveyor equipped with drivers, the drivers engaging the bottom tray and conveying the container forward on a roller conveyor, a sliding surface or the like.
  • the conveyor is divided for crossing its path, and an additional conveyor and a control device are provided for a synchronous movement of the two conveyors.
  • This additional conveyor can engage the lid tray at the top or in the area of the side walls. It ensures that the lid tray is conveyed vertically above the bottom tray.
  • the movement of the two conveyors is synchronized by means of a control device, in that the same speeds act to be brought. All this happens while the fastening strip is wrapped around the unit made of the container and the goods, the tension is applied to the fastening strip and the two ends of the fastening strip are connected.
  • the control device can be implemented in a wide variety of ways. Two completely separate drives can be provided for the two conveyors, which are only synchronized. However, it is also possible to indirectly remove the drive of the second conveyor from the drive of the first conveyor or to branch both drives from a common main drive shaft.

  • suction nozzles connected to a vacuum source are provided on the other side of the fastening strip. These suction nozzles lead the end of the fastening strip, which has been released from the brake, downwards in a targeted manner, thereby taking over part of the holding force and at the same time tightening the end of the fastening strip, so that the gluing station provides a glue nozzle specifically and reliably with glue to the end of the fastening strip can. This happens in the immediate vicinity of the lid of the container.
  • the roller carrier pressing on the front end of the fastening strip is driven or controlled relative to the constant speed of the conveyor with a different speed and relative to the stationary roller conveyor. Its movement takes place in such a way that when the edge of the rear wall of the container is passed over to the lid, the roller carrier has a higher speed than the constant speed of the conveyed unit of container and goods. To this extent, the front end of the fastening strip is pressed onto the cover. This accelerated forward movement of the roller carrier is ended, the roller carrier remaining in its pressing relative position. Its movement is reduced and finally stopped, at the same time the front area of the unit has passed over the stationary roller conveyor, so that the rear end of the fastening strip is increasingly placed on the lid of the container in accordance with the continuous conveyance of the container.

All operations on the unit 15 take place during the continuous conveying of the unit 15 via the conveyor 14 and the additional conveyor 43.
  • FIG. 18 finally illustrates a further intermediate position in which the pair of clamping rollers 13 and the gripping jaws 38 of the rocker 11 have already gripped a front end 5 on the material web 9, from which the next fastening strip 4 for the next unit 15 is to be pulled off. While the rear moth is accelerated against the conveying direction, the unit 15 passes under the stationary roller conveyor 18 and possibly subsequent pressure rollers 23, so that the connection point between the front end 5 and the rear end 6 of the fastening strip remains pressed until the Glue has set. The rear folder 49 releases the path of movement 36 of the rocker 11 or of the pair of pinch rollers 13, so that it can pivot through the cutouts 35 before the next unit 15 has reached the cutouts 35.
