Definitions
- the present invention relates to a packaging machine, filled with the packaging trays with a packaged goods and sealed with a lid film, the packaging trays are cyclically moved along the packaging machine and the lidding film is stretched for their accurate positioning on the packaging trays. Furthermore, the present invention relates to a method for sealing a lidding film to packaging trays.
- Packaging goods especially food, are increasingly being packed in plastic packaging nowadays.
- plastic packaging consist of a so-called packaging tray, in which the packaged goods are filled and a lid film, which is sealed to the packaging tray and sealed with the packaging tray.
- lidding films are increasingly printed with trademarks or product information, so that an exact positioning of the printed image of the lidding film on the packaging tray must be made before sealing.
- the present invention is therefore based on the object of providing a packaging machine, or a method for sealing the lidding film to packaging troughs, in which the printed images of the printed lidding foil can be positioned very precisely on the packaging troughs and sealed to them.
- the object is achieved according to the invention by a packaging machine, filled with the packaging trays with a packaged goods and sealed with a lid film in which the lidding film is stretched to their exact positioning on the packaging trays and having a stretching device that is not based on the movement of the packaging trays ,
- the packaging machine according to the invention is simple and inexpensive to manufacture and operate.
- the stretching device has a clamping means with which the cover film is fixed so that it can be stretched.
- a clamping means every known in the art clamping means in question, with which the fixation of the cover sheet can be done quickly, reversibly and without affecting.
- an inflatable tube is mentioned here.
- the stretching device preferably has a displacement means with which the clamping means can be displaced such that the cover film stretches in the desired length.
- the displacement means is infinitely adjustable.
- the packaging machine according to the invention has a photocell, with the print marks, which are each arranged between two printed images, are detected.
- the lidding film is rolled up on a film roll, which in turn is mounted on a roll holder.
- the lidding film is preferably tensioned by a dancer.
- Another object of the present invention is a method for sealing a lid film to packaging trays, which are cyclically moved along a packaging machine in which the lidding film is stretched for their exact positioning on the packaging trays and then sealed and in which the stretching of the lidding film not under the With the help of the movement of the packaging troughs takes place.
- the method according to the invention has the advantage that the printed images on the cover film can be positioned very precisely on the packaging troughs.
- the process is simple and inexpensive to perform.
- the lid film is fixed to at least one packaging tray, particularly preferably sealed and rolled the cover sheet with the cyclical advantage of the packaging tray of a roll of film and once the preference of the packaging tray is completed, fixed by a clamping means, stretched and then sealed.
- the actual position of print marks is written during the unwinding of the cover sheet.
- the thus determined actual position is compared with a desired position and based on the comparison, the degree of elongation (stretching) of the lid film is determined.
- the degree of elongation (stretching) of the lid film is determined. To avoid overexpansion of the film limits the amount of maximum stretch through the film formulation.
- Figure 1 shows a lid film stretching device with a photocell and a stretching device with Wegvorgabe.
- FIG. 2 shows a cover film stretching device with a displaceable photocell.
- Figure 1 shows the packaging machine according to the invention (only partially shown), in particular the stretching device and seal.
- the packaging troughs 1 are transported along the transport direction indicated by arrow 12 on the packaging machine.
- the skilled person understands that several packaging trays can be arranged one behind the other in the plane of the paper.
- the lidding film 2 is sealed onto the respective packaging cavities 1 'located in the sealing chamber.
- the lower sealing tool 15 as shown by the double arrow, moved up and down, so that the lid film 2 is sealed under the influence of temperature and pressure on the packaging trays 1 '.
- the lidding film Since the lidding film is connected to the packaging troughs V, during the advancement of the packaging troughs, the lidding film 2 is unrolled from the film roll 9, which is arranged on the roll holder 10. During the rolling process, the actual position of the print marks 8, which are located on the cover film and each delimiting a printed image, determined and formed in a central control unit, the difference between the actual value and a predetermined target value. This difference is then the measure of the stretch length, which results from the difference between the actual and desired value.
- the clamping means 5 which in the present case is an inflatable tube is activated, which Cover foil 2 fixed. Subsequently, the cover sheet is stretched with the displacement means 6 by the calculated amount (stretched).
- the displacement means is displaced counter to the running direction of the cover film.
- the shifting means is driven in the present case by a stepping motor or servomotor. Since the lidding film is fixed in the stretching device 4, it is stretched (stretched). As soon as the stretching of the lidding film has been completed, ie the lidding foil is placed exactly above the respective packaging troughs, the sealing takes place in the prescribed manner. After the sealing operation is completed, the clamping means 5 is released again and the displacement means 6 is returned to its original position. The movement of the displacement means is symbolized by the double arrow.
- the process is modified as follows. First, the printed image of the top film as exactly as possible on the Sub-film or deep-drawn therein packaging troughs and then determined by means of a measurement of the distance between the photocell 7 and the reference pressure mark 8 '. This distance is the so-called target value, which is transmitted for example via a control panel to a central control unit. Thereafter, the machine is turned on and the lidding film 2 sealed to the packaging tray 1 '. In each case, the bottom foil containing the packaging troughs is unrolled and the lidding foil sealed to these packaging troughs is unrolled, and with the photocell 7 the actual position of the pressure markers is determined.
- the difference between the nominal position and the actual position is the measure of the respective stretching length. If the required stretching length exceeds the maximum stretching length permissible for the material, then the stretching of the cover film is limited to this maximum stretching length.
- the upper film is fixed after completion of the preference by means of the clamping means 5 and the displacement means 6 displaced according to the predetermined stretching length against the film travel direction.
- the determined target value is stored in the recipe of the film or the product to this film in the machine.
- the print image is now automatically and extremely accurately positioned by the system by determining the print mark actual position and subsequent stretching on the lower film or the associated packaging troughs.
- the maximum stretching length per stretch is also limited in this case in order to avoid tearing of the cover film. This maximum stretching length is also part of the stored recipe.
- FIG. 2 shows a cover film stretching device according to FIG. 1, except that in the present case the photocell is displaceably mounted on the photocell, which is represented by the double arrow. Furthermore, the stretching device according to FIG. 2 does not have a displacement means with path presetting but a displacement means with a position deactivation. Otherwise, the comments on FIG. 1 apply.
- the photocell is displaceable in and against the direction of film travel. Means of manual shift in this case, the photocell, the target position of the print mark is set for the respective type of film. The At first, the photocell registers whether a print mark has passed the photocell when the film has been printed. After completion of the preferential stretching device 4, the lid film 2 is stretched until the photocell 7 detects the passed print mark again.
- the stretching device 4 is driven by a cylinder (not shown), which can not be given a route specification.
- a cylinder not shown
- the stretching process is terminated and the film is fixed by sealing to the packaging trays. If the print mark is not detected, the full available stroke of the cylinder is executed.
- This embodiment of the present invention is particularly suitable for drives of the stretching device 4 without Wegvorgabe, such as cylinders.
