Definitions

  • the present invention relates to a sealing station according to the preamble of claim 1.
  • Such a sealing station is from DE 10 2012 006 696 A1 and from the DE 10 2018 114 263 A1 known.
  • the product protection plates used within these sealing stations which are arranged on the underside of a sealing plate, have the function of reducing the heat emitted by the sealing plate onto the product placed in deep-drawn troughs or packaging trays.
  • product protection plates are removably attached to the sealing plate for cleaning or maintenance, so silicone applied over the screw head makes it difficult to install and remove a product protection plate.
  • this is due to the fact that the silicone first has to be laboriously scraped off in order to remove the product protection plate.
  • new silicone must be applied.
  • the associated curing time increases tool downtime, which leads to increased downtime of the packaging machine.
  • the object of the invention is to make available a sealing station with a product protection plate, with which packaging which is perfect in terms of appearance can be produced in particular.
  • the invention relates to a sealing station for a packaging machine, which is present in particular in the form of a thermoforming packaging machine or in the form of a tray sealing machine.
  • the sealing station according to the invention has a lower part of the sealing tool for accommodating deep-drawn troughs or packaging trays and an upper part of the sealing tool positioned above it with at least one heatable sealing plate.
  • the sealing plate is designed to close the deep-drawn troughs or packaging trays accommodated by the lower part of the sealing tool with an upper film, with at least one product protection plate being attached to an underside of the sealing plate. Its function is to reduce heat transfer from the sealing plate to the product to be packaged.
  • the upper part of the sealing tool has at least one fastening mechanism for the detachable fastening of the product protection plate to the underside of the sealing plate. This means that the product protection plate can be removed for service or cleaning purposes, for example.
  • the attachment mechanism between the sealing plate and the product protection plate comprises at least one magnetic locking unit for generating a magnetic holding force for attaching the product protection plate to the sealing plate, at least one hook-in locking unit for attaching opposite outer sides of the product protection plate to these facing areas of the sealing plate, or at least one gravity locking unit that is used to do so is designed to lock the product protection plate on the upper part of the sealing tool by means of a gravitational force which is exerted by the product protection plate in the installed state and points away from the sealing plate positioned above it.
  • the fastening means proposed according to the invention are formed between the sealing plate and the product protection plate, i.e. on opposite sides thereof, the underside of the product protection plate facing away from the sealing plate and facing the top film remains free of assembly means and therefore does not need to have any bores for such assembly means.
  • the underside of the product protection panel can be finished with a flat surface that will not leave marks on the top film.
  • the three above-mentioned alternatives according to the invention for fastening the product protection plate can be implemented easily and cost-effectively at the sealing station from a structural point of view. Furthermore, the respective alternatives enable the product protection plate to be quickly and easily installed and removed at the sealing station. Above all, however, it is possible to avoid imprints on the top or lid film. Furthermore, downtimes of the sealing station can be reduced using the attachment alternatives according to the invention, since the product protection plate can be installed and removed at the sealing station without great effort, in particular within a short time.
  • the magnetic locking unit preferably has at least one permanent magnet which is attached to the sealing plate or to the product protection plate.
  • the permanent magnet could be attached, for example, to an underside of the sealing plate facing the product protection plate, in particular centrally above the product protection plate.
  • Such a permanent magnet can be produced inexpensively and can be integrated as a functional component in a compact manner at the sealing station.
  • the magnetic locking unit has at least one component made of a soft magnetic material (hereinafter also referred to as "soft magnetic component”), which is attached to the sealing plate or the product protection plate. If this component is attached to the product protection plate, the permanent magnet is attached to the sealing plate and vice versa.
  • soft magnetic component a soft magnetic material
  • the permanent magnet and the component made of a soft magnetic material can be positioned opposite one another in order to generate a desired holding force for attaching the product protection plate to the sealing plate.
  • the permanent magnet has a trough-like centering recess facing the soft-magnetic component in the assembled state of the product protection plate, in which at least part of the soft-magnetic component is positively accommodated.
  • the permanent magnet and the soft-magnetic component together form a centering unit.
  • the centering depression can in particular be oval in shape.
  • the product protection plate can thus be attached to the sealing plate in a stable position.
  • the permanent magnet and/or the component made of the soft-magnetic material have at least a partial plastic sheathing. This enables the product protection plate to be installed and removed gently and with less noise at the sealing station.
  • a variant provides that the permanent magnet and the component made of the soft magnetic material are completely embedded in plastic. This full encapsulation has the advantage that manufacturing tolerances can be better compensated and it prevents mechanical stresses in the magnetic components.
  • a preferred variant provides that the permanent magnet or the component made of the soft-magnetic material is fastened within a recess formed on the sealing plate. This favors a flat assembly of the sealing plate and the product protection plate. In this way, shortened lifting cycles can be achieved during operation of the sealing station.
  • the soft-magnetic component in the mounted state is screwed to an upper side of the product protection plate facing the sealing plate, with a part of the soft-magnetic component protruding from the upper side of the product protection plate forming a negative shape for the centering recess formed in the permanent magnet.
  • Their respective shapes can be secured against twisting relative to one another. It is thus possible for the permanent magnet, together with the soft-magnetic component, to form a centering unit in order to attach the product protection plate to the sealing plate in a predetermined position and orientation.
  • the sealing plate preferably forms a receptacle on its underside that is shaped to accommodate the product protection plate. When assembled, this results in a flat, cassette-like module.
  • the hooking locking unit has at least one hooking protrusion formed on a first outer side of the product protection plate and at least one elastic locking clip arranged on a second outer side of the product protection plate opposite the first.
  • the fastening means which are shifted to opposite outer sides of the product protection plate, enable the product protection plate to be easily installed and removed at the sealing station.
  • the hooking projection can be hooked inside an indentation of the sealing plate.
  • the locking bracket can snap into a projection of the sealing plate.
  • the hooking projection is formed integrally with the product protection panel, i.e. in one piece with it.
  • the elastic locking clip can be screwed onto the product protection plate on its upper side facing the sealing plate.
  • the locking bracket preferably has a locking tongue which can snap onto the projection formed on the sealing plate in order to secure the hinged product protection plate on the sealing plate. It is conceivable that the elastic locking bracket can be released from a locked state on the sealing plate using a screwdriver, so that the product protection plate can be easily removed from the sealing station by an operator, for example for service, cleaning and/or conversion work.
  • the spacer is preferably arranged on the sealing plate within the receptacle formed thereon for receiving the product protection plate, for example screwed tight therein.
  • An advantageous variant provides for a total of four spacers, which are distributed within the mounting recess around the permanent magnet fastened therein.
  • the gravity locking unit is designed to unlock the product protection plate in the removed state of the upper part of the sealing tool when it is turned upside down by simply pressing the product protection plate in the direction of gravity.
  • a gravity locking mechanism can be in the function of a push-to-open lock, in which variant the pushing can be facilitated by the gravity of the product protection panel to bring it into an unlocked state for removal.
  • the gravity locking unit has at least two spherical locking bodies. It is conceivable that these two balls are accommodated within guide bores formed on the sealing plate, which also form part of the gravity locking unit. These guide bores can be such that the two balls tend to be moved towards one another to lock the product protection plate and tend to be moved apart to unlock the product protection plate.
  • the guide bores can have a bore cross-section that tapers towards the product protection plate.
  • the product protection plate has at least two centering bolts on its upper side and the sealing plate has two corresponding centering holes.
  • the centering bolts make it easier to install and remove the product protection plate at the sealing station.
  • the gravity locking unit has a bolt attached to the product protection plate in the form of a countersunk screw, which can be pushed headform first into a mounting opening formed on the sealing plate to attach the product protection plate to the sealing plate.
  • the head shape formed on the bolt can be secured to the gravity locking unit by means of the two balls.
  • the product protection plate preferably has an underside facing the lower part of the sealing tool in the installed state, with a surface free of bores.
  • the flat surface facing the product prevents marks from forming on the lidding film.
  • the invention also relates to a packaging machine that is in the form of a thermoforming packaging machine or in the form of a tray sealing machine (also known as a "tray sealer" in technical circles) and has a sealing station according to the invention.
