Definitions

  • the present invention relates to a method and a device for packaging and sealing small articles such as chocolate pieces or bars on one or more article lines.
  • Sealing in intermittent packaging machines is generally done in cycles, like all other processing steps. This means that processing, particularly sealing, is carried out at one station while the product is at a standstill. After the processing process has been completed, the respective product is transported to the following position, where the next processing step is carried out. In the event that the processing time is not sufficient, for example when sealing at a processing station, further subsequent stations are equipped with a sealing device in order to achieve the required sealing time.
  • the main influencing factors for successful sealing of packaging are the parameters sealing temperature, sealing pressure and sealing time, which are directly related to the properties of the packaging to be sealed (e.g. type and thickness of the packaging, sealing coating).
  • the type of packaging determines its thermal conductivity properties, the melting temperature and the shrinkage behavior due to temperature input.
  • the thickness of the packaging determines the time for heat to pass through to the sealing layer, the insulation behavior between the bottom layer and the item, and the compression behavior under pressure.
  • the seal coating is important in terms of the melting point of the coating. There are also other boundary conditions that limit the choice of sealing parameters. This is particularly important for pressure and temperature sensitive products (e.g. chocolate).
  • the fold is fixed by sealing by bringing a sealing element into contact with the packaging from the outside after the folded wrapper has been produced in order to connect the packaging layers to one another, preferably at the bottom of the product.
  • the product is arranged on the inside of the packaging and applies the corresponding counter pressure.
  • this results in one Limitation of the possible sealing pressure, otherwise the products will be crushed.
  • heat is introduced into the packaging from the outside through the sealing element in order to enable the sealing process.
  • a certain amount of heat penetrates further than just the packaging and may also heat the product.
  • chocolate products have very strict limits until destruction occurs.
  • the parameters sealing pressure, sealing temperature and sealing time can be selected to a very limited extent.
  • This cyclical energy input makes the amount of heat introduced very difficult to control and depends on other parameters that are sometimes difficult to influence (such as component tolerances). For temperature-insensitive products, this does not play a significant role, as significantly more heat is introduced into the sealing point than is necessary for sealing, which compensates for tolerances in the amount of heat transferred. For temperature-sensitive products, for example, an additional inner wrap can serve as a thermal barrier.
  • the present invention is based on the object of enabling constant sealing times, sealing pressures and sealing temperatures, regardless of the speed of the packaging process, in order to achieve a reproducible seal without damaging the articles.
  • the present invention provides the method according to claim 1 and the device according to claim 8.
  • the method according to the invention is used for packaging and sealing small items such as chocolate pieces or bars on one or more article lanes and comprises the steps: Step A: Packaging the small items by assigning a packaging material to each item and folding the packaging material around this item.
  • Step B Grouping at least two of the individually packaged items into a group of packaged items.
  • Step C Simultaneous sealing of the packaging of all individually packaged items in the group of packaged items.
  • the process steps can be repeated as often as desired with additional items according to the assembly line production principle.
  • the essential feature of the invention is the decoupling of the sealing process from a speed-dependent packaging process.
  • groups are formed from individual products or items from a pre-process, e.g. wrapped synchronously in packaging, and these are passed on to a time-controlled follow-up process in which sealing takes place.
  • the sealing time can vary be significantly adapted to the requirements. This means that the necessary sealing time is achieved despite short cycle rates.
  • the dimensioning is carried out in such a way that the necessary sealing time is available for the individual products in the group at maximum packaging speed. Because the sealing process is decoupled from the pre-process in terms of time and drive, the sealing stamps are lifted from the product after a constant sealing time, even if the preceding impact process is slowed down and therefore takes place over a longer cycle time. This ensures a constant sealing time.
  • each individual product within the group comes into contact with its own seal stamp once.
  • This seal stamp preferably remains on the product for a constant, defined period of time in order to bring about the seal.
  • tolerance compensation e.g. using a spring effect
  • height tolerances can be compensated for, resulting in the same sealing pressures for all products.
  • step A individual articles arranged in rows are transported along the respective article path, preferably one after the other over at least one rotary head. This means that the articles can go to different work stations one after the other and be processed at each of these work stations.
  • each article in step A successively passes through at least two different work stations, the packaging associated with the article being folded successively in each of these work stations by different folding means. This makes it possible to carry out different folding steps one after the other in order to finish packing the item at the end of the packaging process. Ideally, all sides of the finished packaged item are covered with packaging material.
  • each item in Step A is individually packaged in an intermittent process, remaining at each of these workstations for a uniform dwell time.
  • each folding step of the packaging can be carried out stationary, so that the construction of a packaging device can be compared to a continuously operating packaging machine the folding steps are carried out during the movement of the articles and appropriate folding means are to be provided, can be significantly simplified.
  • step C it can prove to be practical if the sealing time in which the packaging of each item in the respective group is sealed in step C is longer than the dwell time in step A. This means that pressure- and temperature-sensitive items such as chocolate pieces or bars can be packaged particularly gently and be sealed.
  • each article of the respective group in step C remains preferably stationary in a sealing device and/or is kept in contact with a respective sealing element during a sealing time in which the packaging of each article of the respective group is sealed, preferably the sealing time for each item in the group begins and/or ends at the same time.
  • the articles can also be delivered synchronously with the individual cycle of the machine if this is more favorable for the subsequent process (e.g. if groups have to be formed in the subsequent process that are not the same as the group size in the sealing process).
  • the articles are fed to a grouping device one after the other in step B to form the respective group, preferably individually, the grouping device being designed to transport the articles of the respective group in groups for subsequent sealing in step C, the grouping device particularly preferably being independent of one of the articles packaging packaging device is movable.
  • the articles can be stowed on the respective article lane to form a group or fed from a plurality of article lanes to a common article lane.
  • the speeds and/or the distances of the items forming the group are changed, preferably reduced, compared to step A.
  • each article of the respective group is assigned at least one sealing element of its own, preferably each sealing element being regulated individually, preferably depending on at least one parameter measured on the sealing element, such as a sealing duration and/or a sealing temperature and/or or a seal print. This makes it possible to achieve particularly consistent sealing results even with unavoidable manufacturing tolerances.
  • step A it may prove useful if the articles in step A are conveyed through at least one circular article path section. This is done, for example, in a packaging machine with at least one rotary head, which each article passes through one after the other in the packaging process.
  • step B and/or step C are arranged and/or transported on a linear article path section. This simplifies the formation of the group of packaged items as well as the group-by-group transport into and out of the sealing device.
  • step C the orientations and/or the speeds and/or the mutual distances of the articles of a respective group are constant and/or uniform. If the orientations and/or the speeds and/or the mutual distances of the articles are constant, the respective article does not change its orientation and/or its speed and/or its distance from an adjacent article, at least during the sealing in step C. If the orientations and/or the speeds and/or the spacings of the articles are uniform, all articles will have the same orientations and/or the same speeds and/or the same spacings at least during the sealing in step C.
  • the articles are preferably sealed in a stationary manner in the sealing device, i.e. the articles do not move during sealing. However, it is also possible for the articles in step C to be transported in groups at a constant speed, with the sealing taking place, for example, in a mobile sealing device on the way to a delivery station.

  • the device comprises at least two transport units which are designed to move back and forth between the packaging device/grouping device and the sealing device, the transport units being designed in such a way that one of the transport units always alternately picks up packaged items from the packaging device, while the other transport unit provides the group of articles for sealing in the sealing device.
  • the sealing device has its own sealing stamp for each article in the group, the sealing stamp preferably being resiliently mounted to compensate for tolerances with respect to the article to be sealed, the sealing stamp preferably being moved into a non-use position when the packaging device is stopped.
