Definitions
- the present invention relates to a tray sealer for thermoforming a skinnable top film and detecting defective packages.
- WO 2015091404 A1 discloses a tray sealer for sealing a tray with a skinnable top film.
- the top film is here heated using a dome-shaped plate, which is adapted to be moved relative to a dome-shaped die, and is pulled by the dome-shaped plate itself into the dome-shaped die for the purpose of forming.
- the movable and heatable dome-shaped plate involves a high constructional outlay.
- EP 2815983 A1 discloses a tray sealer, which, in a similar manner, is configured for heating a skinnable top film by applying it to a heated interior wall of a dome-shaped die.
- heated air is here guided via the sealing tool through the dome-shaped die and onto the top film and, subsequently, this air is extracted via the common ducts from the space between the sealing tool upper part and the preheated top film.
- This process combination of overpressure and evacuation is disadvantageous as regards the period of time needed until the thermoforming process ends in the dome-shaped die.
- the tray sealer includes a control unit and a sealing station, which comprises a tool upper part, a clamping frame and a tool lower part, wherein the interior of the tool upper part has arranged therein a dome-shaped die for deforming a skinnable top film, preferably a top film having a thickness of less than 200 ⁇ m.
- the dome-shaped die comprises at least a first channel
- the tool upper part comprises a second channel
- the dome-shaped die has an inner contact surface.
- the clamping frame may be configured to clamp the top film in position on the tool upper part in a gas-tight manner so as to define an upper chamber within the tool upper part.
- One embodiment of the invention may be the inclusion of a vacuum sensor (pressure sensor), which is connected to the control unit, may be provided between the dome-shaped die and a vacuum generator, the control unit being configured to detect a tear in the film on the basis of the pressure profile (viz. pressure curve).
- the top film can be thermoformed into the dome-shaped die and a possible tear in the film caused during the thermoforming process would be detected.
- a pressure profile ascertained using the vacuum sensor may be compared with a predetermined pressure profile or a pressure profile to be expected. If the pressure profile ascertained should deviate from the predetermined pressure profile and if the deviation should exceed a predetermined tolerance, the control unit will interpret this as an indication of a tear in the film.
- the deviation may be measured during the entire thermoforming process.
- the deviation may occur in the form of a pressure increase or an insufficient gradient of the evacuation curve and may be caused by a tear in the film. It is also imaginable that a predetermined final vacuum value is not accomplished due to a tear in the film and that this may be considered to be an indication of a tear in the film.
- Such a tear in the film may be primarily caused by an unequal temperature distribution in the skin film, since, due to the radiant heat of the sealing surface, the skin film may be heated more intensively in this area than in other areas. In particular when the skin film comes into contact with the sealing surface during the thermoforming process, this may have a negative effect and result in film tearing. Likewise, an already pre-damaged film would be detected during the thermoforming process. Hence, a production of defective packages, which would have to be removed later on, will be prevented, or situations will be prevented, in which the process cannot be duly finished, since, due to leakiness of the top film prior to skinning, a final vacuum cannot be accomplished or can only be accomplished after a long period of time. In one embodiment, it is also imaginable to advance the partially deformed top film and to execute a new thermoforming process with a new film section.
- the dome-shaped die comprises a plurality of venting ducts for thermoforming the top film uniformly and quickly into the interior of the dome-shaped die.
- the venting ducts can also be used for supplying air to the sealing tool, so as to allow the top film to move downwards into contact with the product and the inner sides as well as to a position of contact with the tray edge.
- the dome-shaped die has a sealing surface for sealing the top film onto the tray edge of the tray using pressure and heat.
- the dome-shaped die may be movable between an upper position for deforming the skinnable top film and a lower position for sealing the top film onto the tray edge of at least one tray.
- a seal may be provided at a transition of the first channel from the dome-shaped die to the second channel of the tool upper part, so that the chamber can be evacuated.
- the seal may also be provided in the event that the top film may be in contact with the lower side of the dome-shaped die and divides the chamber into two areas.
- a subchamber may be located between the top film and the sealing tool, but outside the dome-shaped die, and a second subchamber may be defined by the interior of the dome-shaped die and the top film.
- the method according to the present invention which may be used for operating a tray sealer including a control unit as well as a sealing station comprising a tool upper part, a clamping frame and a tool lower part, wherein the tool upper part receives therein a dome-shaped die for deforming a skinnable top film, wherein the dome-shaped die comprises at least a first channel, wherein the tool upper part comprises a second channel, wherein the dome-shaped die has an inner contact surface, and wherein the clamping frame may be configured to clamp the top film in position on the tool upper part in a gas-tight manner so as to define a chamber within the tool upper part, is wherein, using a vacuum sensor provided between the dome-shaped die and a vacuum generator, a negative pressure is measured, and that the control unit detects a tear in the film on the basis of the pressure profile (viz. pressure curve).
- a vacuum sensor provided between the dome-shaped die and a vacuum generator
- control unit will show a message on a display, when a tear in the film is detected.
- the operator is informed of the reason for the interruption of the process and can, if necessary, adapt parameters for the next new thermoforming process so as to avoid further film tearing.
- control unit will not start or will discontinue a sealing process when a tear in the film is detected, since the packages in question are at least partially defective and thus useless.
- air will be supplied to the tool upper part and the top film will be advanced in the conveying direction, when a tear in the film is detected, so as thermoform, in a further attempt, a subsequent new film section into the dome-shaped die.
- it is imaginable to discontinue the packaging process after film tearing has occurred three times in succession, so as to adapt process parameters or search for other causes of error.
- the pressure profile may be used as a basis for detecting that the top film is in contact with the inner contact surface of the dome-shaped die, whereupon the next process step may be started or initiated. Time settings with the usual additional safety buffers are thus no longer necessary.
