Definitions

  • the present invention relates to a method for transferring a shrinking device from a production mode to a stand-by mode and a shrinking device according to the features of the independent claims.
  • the present invention deals with shrinking devices that have optimized energy management or are operated with optimized energy management.
  • a shrink tunnel generally includes a revolving endless conveyor, which runs through a housing, at least over a section, which delimits the shrink tunnel. Furthermore, a shrink tunnel usually includes several heating elements and also fans or blowers in order to generate the required hot air and then distribute it in the interior of the shrink tunnel. In order to achieve a particularly even distribution of the hot air, after it has been generated, the hot air is preferably guided partly into so-called shaft walls and partly into a floor chamber which is located directly below the conveying means of the shrink tunnel. Thus, the articles wrapped with shrink film are preferably actively loaded with shrink medium from at least three sides.
  • Shrink tunnels have a high demand for thermal energy, which means that the operator incurs not inconsiderable costs.
  • the generation of the shrink medium is the largest energy consumer in a shrink tunnel.
  • a shrink tunnel In order to reduce the energy consumption of a shrink tunnel, it can be put into a so-called stand-by mode in certain operating states in which the shrink tunnel is not required for production. One or more consumers of the shrink tunnel are reduced in their performance and thus the energy consumption is reduced compared to the production operation.
  • Such a shrink tunnel or such a method for operating a shrink tunnel is, for example, from DE 10 2010 011 640 A1 out.
  • a shrink tunnel is described here which, in addition to the conventional production mode, has a further so-called stand-by mode, with the shrink tunnel being operated with a reduced power compared to the production mode by means of this stand-by mode.
  • the change between the conventional production mode and the further stand-by mode takes place in a time and/or signal-controlled manner.
  • stand-by mode When switching to stand-by mode, a number of measures are taken that lead to a reduction in the energy requirement of the shrink tunnel.
  • One measure would be, for example, that the existing desired temperature can be set to a stand-by temperature that is reduced compared to the desired temperature, with the result that less heating power is required.
  • Another measure would be, for example, reducing the transport speed of the transporter on the shrink tunnel side in order to minimize the energy or heat discharge from the tunnel.
  • switching off the cooling of the shrink tunnel-side conveyor and the cooling of the packs that leave the shrink tunnel would also be measures to reduce the energy requirement. Switching off one fan of the heating means per tunnel zone, provided that each tunnel zone is assigned at least two electrically operated fans, results in a reduced energy requirement.
  • the so-called stand-by mode involves another measure, with the two openings in the input and Exit area of the shrink tunnel are at least partially closed.
  • the shrink tunnel entrance area and the shrink tunnel exit area are logically open so wide that the packs can enter and exit the shrink tunnel unhindered.
  • the shrink tunnel entry area and the shrink tunnel exit area are either opened or closed when changing between the respective operating modes, ie between the production mode and the stand-by mode.
  • the change between the two operating modes is also triggered in a time- and/or signal-controlled manner.
  • Such a controller for operating a shrink tunnel and such a shrink tunnel itself are disclosed, for example, in the published application DE 10 2010 020 957 A1 out.
  • the disclosure document DE 10 2013 104 417 A1 describes a method for converting a shrink tunnel into a production mode, which comprises at least opening a shrink tunnel entry area and/or opening a shrink tunnel exit area, and also at least one of the following steps: a) increasing the shrink tunnel interior temperature to a predefined setpoint; b) turning on the conveyor or increasing the speed of the conveyor to a predetermined setpoint; c) Turning on or increasing the chain cooling capacity to a predetermined setpoint; Switching on or increasing the pack cooling capacity to a predetermined target value, with the opening of the shrink tunnel entry area and/or the opening of the shrink tunnel exit area taking place at the earliest with one of steps a), b) and/or c).
  • the object of the present invention is now to optimize the stated prior art in such a way that the energy requirement of the shrink tunnel is further optimized in different operating modes.
  • the products to be applied within the shrinking device by means of shrinking medium or shrinking agents are, for example, by a
  • a plurality of articles formed, which are wrapped with a packaging material are wrapped with a packaging material.
  • the articles are combined into article groups or article combinations in a grouping device. These are then wrapped with the packaging material in a wrapping device.
  • a shrink film is wrapped around the assembly of articles in the wrapping device.
  • the packaging material is preferably formed from a thermoplastic flat shrink material, in particular a shrink film, which contracts when heat is applied and thus rests against the outwardly facing outer lateral surfaces of the articles, resulting in a close bond in the form of a packaging unit, which packaging unit is also referred to below as a shrink pack referred to as.
  • the shrink material may be a shrink tube or label that is placed around an article and shrunk onto the article within the shrink apparatus.
  • a shrink label it may be necessary to fix its position on the article by means of an adhesive dot or similar, at least temporarily before the start of the shrink process. This or a similar adhesive point fixation can also be the case or be carried out with wrapped shrink films.
  • the articles are preferably containers, in particular beverage containers such as bottles, cans or the like made of glass, plastic, metal etc.
  • the shrinking device has an interior space with a transport section, the articles being preferably transported within the shrinking device in at least one lane.
  • the upper surfaces of the conveying means, on which articles (possibly including foil) or containers are transported, can essentially be understood as the transport route.
  • the shrinking device includes shrinking agent introduction devices which are designed to apply shrinking agent to the articles wrapped with packaging material. These are preferably first lateral shrinkage agent introduction devices and/or second lower shrinkage agent introduction devices and/or third upper shrinkage agent introduction devices. According to one embodiment, it is provided that the lateral shrinking agent introduction devices are designed as shaft walls, each of which has at least one outflow surface for shrinking agents directed towards the respective transport path.
  • the number of shaft walls can define the number of transport lanes formed.
  • so-called outer shaft walls are preferably provided on both sides of, in particular above, the transport section, each having an outflow surface facing the interior of the shrinking device and a closed side surface facing the housing of the shrinking device.
  • An inner (or also called central) shaft wall is arranged in the middle or approximately in the middle between the two outer shaft walls, the two essentially vertical side surfaces of which are each designed as outflow surfaces parallel to the transport direction.
  • the inner shaft wall thus feeds shrinking medium or shrinking agent in particular to the two parallel transport paths, with the application of shrinking medium to the two parallel transport paths having or can have approximately the same magnitude.
  • four shaft walls for dispensing shrinking medium can be arranged in the shrinking device, two outer ones, as shown above, and two inner ones, with the two inner ones each having only one outflow surface from which shrinking medium emerges during production .

  • the at least two partial areas can be arranged one behind the other in the transport direction.
  • One embodiment can provide that in the second partial area downstream in the direction of transport there is no supply or a reduced supply of shrinking agent via the second shrinking agent device.
