Definitions

  • the invention relates to a method for packaging a preformed piece goods according to the preamble of claim 1 and an installation for carrying out the method.
  • Self-service stalls require good packaging of the goods presented. It is common to fill the goods into a container, a so-called tray, and to seal the opening with an airtight seal.
  • the trays are generally produced from a plastic film in a deep-drawing process and have edge parts extending outwards at right angles to the opening on an open side. These edge parts are connected airtight by welding or gluing with a film that serves as a lid.
  • the opening is aligned upwards and the goods are fed in from above.
  • the shape of the tray is adapted to this for a preformed piece goods. This saves packaging material, the space and Space requirements are reduced and the risk of the stucco material being displaced or falling apart during transport or in any other way within the tray.
  • the size of the stucco to be packaged has relatively large tolerances, such as for molded foods, especially if they consist of several loosely assembled parts, such as a sandwich, it is difficult to pass the stuck through the opening in bring the tray without touching or soiling the edge parts at the openings.
  • the object of the invention is to pack the piece goods more securely and easily and to improve the degree of automation of corresponding systems. It is solved according to the invention by the features of claim 1.
  • the tray is aligned and held so that its opening is perpendicular.
  • At least one transport device requests the piece goods and / or the tray to one another such that the lower edge of the piece goods in Height of the lower edge of the opening.
  • the piece goods are then pushed into the tray.
  • the piece goods and the tray can be aligned very well in an automatic working process so that the piece goods do not hit the edge parts of the tray. If small particles fall off the piece goods during the filling process, for example from the sandwich, they do not fall onto the edge parts, but into an intermediate space between the transport devices.
  • the method is suitable both for prefabricated trays, which are made of a plastic or a plastic-coated material and are placed individually at a distance from each other on a transport device that conveys the trays to a filling station, as well as for systems in which the Trays in front of the filling station are made from a thermoformed plastic film.
  • trays can be arranged one above the other transversely to the transport direction and filled in the different levels at the same time.
  • the method according to the invention can be improved in that the piece goods are mechanically guided when they are introduced into the tray, e.g. by the device for calibrating the piece goods or by a slide which lifts the piece goods from the transport device and serves to bridge an intermediate space between the transport device and the tray.
  • a system for carrying out the method according to the invention regularly comprises a central conveyor device that conveys the trays from a supply station via a filling station, a closing station to a removal station.
  • horizontal or vertical conveyors are useful. They can be designed as circular conveyors, endless conveyors or linear conveyors.
  • the system comprises a deep-drawing device in front of the filling station in order to produce the trays from a deep-drawing film using the deep-drawing process, the deep-drawing film or its conveying device serves to transport the deep-drawn trays which are connected to one another by the deep-drawing film.
  • prefabricated trays are placed individually on the conveyor device at a distance from one another and held there in holding devices.
  • These holding devices expediently work with compressed air or negative pressure, in that the negative pressure attracts the trays to the holding device and, if necessary, holds them in place.
  • the fully filled and closed trays can be ejected mechanically or by compressed air and are transferred to a cross conveyor in an unloading station.
  • the closing station is expediently arranged diametrically to the supply station and the filling station diametrically to the removal station.
  • the supply station and the removal station lie in the same conveying direction, while the filling station and the closing station are arranged in the other conveying direction of the endless conveyor.
  • the individual stations can also be arranged in a row one behind the other. This is particularly expedient if the trays are made from a deep-drawing film in a deep-drawing process.
  • the filling station and the closing station are connected to a deep-drawing tool, followed by a separating tool that separates the filled and closed tray from the deep-drawing film.
  • Such a system can be set up both in one or more horizontal levels and in one or more vertical levels, so that several trays can be filled at the same time. If several filling stations are provided next to each other in the conveying direction, the conveying devices operate in a clocked manner, with a corresponding number of trays being conveyed on each conveying stroke.

  • 5 is a schematic plan view
  • Fig. 9 shows a system with a vertical linear conveyor
  • FIG. 10 shows a variant of FIG. 9.
  • sandwich 2 is made from square bread slices, which are topped and folded. The sandwich is then divided diagonally and the two halves are placed on top of one another accordingly. The thus prepared and preformed sandwich 2 is placed on a conveyor 6.
  • the tray 1 has an opening 3 to which edge parts 4 which extend outward connect.
  • the opening 3 points to the sandwich 2 and is oriented essentially vertically. Small deviations from the vertical do not jeopardize the success according to the invention, but can favor the filling and holding of the sandwich if the opening 3 points slightly upwards.
  • the conveyors 6 and 7 align the tray 1 and the sandwich 2 with one another in such a way that in a filling station 23 (Fig. 6, 7, 8, 9) a lower edge 20 of the sandwich 2 is at the level of the lower edge 19 of the opening 3.
  • the sandwich 2 is calibrated by a piston 10 in the direction 11 towards the opening 3 of the tray 1 and pushed into the tray 1 in the direction 12 with a loading device 17 (FIG. 2 , 3). If parts of the sandwich 2 fall off during this process, they can fall down through an intermediate space 9 and e.g. be disposed of by a collecting container or a conveyor belt.
  • a slide 8 is provided which lifts the sandwich 2 from the conveyor device 6 and bridges the intermediate space 9 by moving it in the direction 13.
  • the sandwich 2 is guided on the one hand by the slide 8 and on the other hand by the piston 10, so that it arrives safely in the tray 1 without damaging or soiling the edge parts 4.

  • 5 shows a simplified top view without a slide 8 and a piston 10.
  • Plants (Fig. 6 to 9) for performing the method according to the invention advantageously have a central conveyor, for example in the form of a horizontal circular conveyor 21, a horizontal endless conveyor 48, a linear conveyor, in which a thermoforming film 38 serves as a conveyor (Fig. 8) and one vertical linear conveyor, in which the deep-drawing film 38 is also used as the conveyor medium serves (Fig. 9). Due to the different systems, the available space and space can be used well.
  • the systems according to FIGS. 6 and 7 work with prefabricated trays 1, which are kept ready in a stack 18 in a supply station 22 and are individually placed on the round conveyor 21.
  • This has mounts 31 with pressure connections 33. If the pressure connections 33 are under vacuum, the trays 1 can be sucked in and held. If the rotary conveyor 21 rotates one position further in the conveying direction 34, a test device 32 checks whether a tray 1 is present in the holder 31. In the next conveying step, the tray 1 reaches a filling station 23, to which sandwiches 2 have in the meantime been conveyed in the direction of 35 via a conveyor belt 29.
  • the loading device 17 now pushes the sandwich 2 into the prepared tray 1, optionally using a piston 10 and / or a slide 8.
  • the filled tray 1 arrives at a closing station 24, in which the opening 3 of the tray 1 is opened by one Sealing device 27 is closed with a film 25, which is held ready on a film roll 26 and optionally guided to the tray 1 via deflection rolls 46. While the tray 1 is being sealed, it is supported on the holder 31. The sealed film of the previously sealed tray is also cut at the same time.
  • the filled and closed tray 47 arrives at a removal station 28 with a conveyor belt 30.
  • the packed sandwich 47 is placed on the conveyor belt 30 by the compressed connections 33 being pressurized with compressed air.
  • the conveyor belt 30 then conveys the trays 47 already deposited in the conveying direction 36. 6 shows a plant in one plane. However, it is also possible to arrange several levels one above the other or one behind the other on the same level, so that several trays 1 can be filled in the filling station 23 at the same time.
