Abstract

The The present invention relates to a packaging machine with transport means, the one sheet web cyclically by a certain feed length in one Transport the transport direction and the feed length depending on from the elongation changeable by the means of transport is.

Description

  • The The present invention relates to a packaging machine with transport means, the one sheet web cyclically by a certain feed length in one Transport the transport direction and the feed length depending on from the elongation changeable by the means of transport is.
  • Packaging machines, in particular so-called form-filling-sealing machines, in which a film web along the packaging machine intermittently transported and thereby deformed, filled and covered with a lid is now usually a length> 10 m, often also sealed 20 m and more on. Therefore, the elongation of the means of transport, For example, the transport chains, the film web along the Transport packaging machine and usually under train be operated, an increasing role. This chain elongation is in the exact positioning of the film web, especially in the area the sealing and separation of the packaging possibly problematic, because there to a millimeter accurate positioning of the packaging trays, which are molded into the film web arrives.
  • It Therefore, the object of the present invention was a packaging machine to disposal to provide in which the disadvantages of chain elongation have been eliminated.
  • Is solved the task with a packaging machine with means of transport, the one sheet web cyclically by a certain feed length in one Transport the transport direction and the feed length depending on from the elongation changeable by the means of transport is.
  • It was for the expert very much amazing and not to expect it with the packaging machine according to the invention manages to compensate for the disadvantages of chain elongation. Thereby is a very exact positioning of the packaging troughs in the film web are molded, especially in the area of the seal and the subsequent one Singulation possible. The packaging machine according to the invention is easy and inexpensive manufacture and operate.
  • According to the invention the packing machine has two means of transport on the right and are arranged to the left of a film web, and these intermittently transport along the packaging machine. This means of transport are usually endless chains, which have brackets with which the Film web reversible non-positive attachable to the chain.
  • The Feed length, to continue the film web with the means of transport at each bar is transported, depends on the format that produced on the packaging machine, and that, depending on the type the packaging, selectable is.
  • According to the invention this is Feed length per Clock in the packaging machine according to the invention not always constant, but depending on the elongation of the Modified transport. Preferably, the elongation Measured permanently or at regular intervals and based on the result of this measurement, the amount of feed changed be or not.
  • Preferably has the packaging machine according to the invention a sensor on which the elongation determined the means of transport.
  • Farther Preferably, the packaging machine has a control unit, for example a computer that receives the signal from the sensor. These Control unit controls a drive means, such as a Motor that interacts with the means of transport and their feed causes. The amount of this feed will be according to the respective measured chain elongation, d. H. changed according to the received signal.
  • Preferably the scheme is such that the respective feed by the amount the chain elongation is reduced.
  • Preferably are arranged at the beginning and / or end drive means for driving the transport. The drive means are preferably electric motors, very particularly preferably so-called servomotors. These engines are regulated by the regulatory unit.
  • Preferably drives each drive means both means of transport simultaneously, d. H. the two transport means are preferably by a rigid shaft, preferably at the beginning and at the end of the packaging machine with each other connected. This shaft is preferably driven by the drive means.
  • In the following, the invention is based on the 1 and 2 explained. These explanations are merely exemplary and do not limit the general inventive concept.
  • 1 schematically shows an embodiment of the packaging machine according to the invention.
  • 2 shows a further embodiment of the packaging machine according to the invention.
  • 1 schematically shows a packaging machine, in which a film web is transported by a chain which is arranged to the right and left of the film web in the direction indicated by the arrow running direction. This film web is initially in a heating station 1 heated and then in the thermoforming station 2 deep-drawn. The packaging trays thus produced are filled with a packaged product, for example with food, and then in a sealing station 3 sealed with a top film. Subsequently, the produced packaging trays are separated in a cutting station. The chains 8th are doing intermittently by the drive motor 6 guided in a circle counterclockwise. According to the invention, the packaging machine has a sensor 5 on, which measures the chain elongation in regular. The signal from this sensor is fed to a control unit (not shown) that controls the engine 6 controls. According to the measured chain elongation, the respective feed of the chains, by the motor 6 erfogt, changed. The expert understands that with constant chain elongation auxh the feed rate is constant. By changing the feed to the amount of chain elongation their influence on the film transport can be eliminated and the packaging troughs, especially in the sealing station 3 and in the cutting station 4 , be positioned very accurately.
  • 2 essentially shows the packaging machine according to 1 , wherein in the present case two drive motors 6 . 7 are provided. Both engines will be like at 1 explained, regulated.
