Definitions

  • the present disclosure relates to a sealing machine according to claim 1 and a method for adjusting characteristics of a sealing machine according to claim 7.
  • the foil is provided in the form of a continuous tube through which the products are pushed and a cross sealing is applied to separate portions of the foil wrapped around a product from the remainder of the foil and at the same time seal the foil with the product within.
  • a second approach uses a sheetlike foil that is not provided in a tubular shape but is formed around the products from its original planar shape.
  • the forming is done using a forming set that guides the sealing material so as to surround the product. This requires a longitudinal sealing of the sealing material above the product. This is achieved by using a sealing station that seals the sealing material by pressing its ends together, thereby forming a fin above the product.
  • the first approach is illustrated in EP 3 505 459 A1 . Due to the varying size of the products, the cross sealing point varies as well. This is compensated for by measuring the height of the products adjusting the speed of the incoming products so as to ensure that the cross sealing point is set at a position where sufficient sealing material is provided for achieving sealing of the foil wrap.
  • control of the relative transport speed is, however, not sufficient for handling different dimensions of products in case of using the second approach for providing a sealing to the products.
  • the sealing machine comprises a transporter for transporting a product along a transport direction, a forming set for forming a sheetlike sealing material around a product transported through the forming set along the transport direction, and a sealing station downstream of the forming set for sealing the sealing material in a direction substantially parallel to the transport direction, the sealing machine further comprising a sensor arranged upstream of the forming set and for measuring a height and/or a width of a product and a control device for receiving a signal from the sensor that is indicative of the height and/or the width of a product and wherein the control device is further configured to control adjusting means associated with the forming set and/or the sealing station to adjust at least one characteristic of the forming set and/or the sealing station based on the signal.
  • the characteristics of the forming set and the sealing station may specifically pertain to production parameters of the forming set and the sealing station that are depending on specific product dimensions. For example, a height of the sealing point at which the sealing station seal the sealing material (usually in a region of the fin of the sealing material) depends on the height of the fin actually obtained and, therefore, also on the dimensions of the product.
  • Controlling the characteristics of the sealing machine makes, according to some embodiments, use of the constant width of the sealing material in a direction perpendicular to the transport direction.
  • This width ensures wrapping of the sealing material around the product, thereby forming a fin of sealing material above the product on which the sealing station can act to apply a sealing.
  • the width of the sealing material will at least be equal to or larger than the sum of two times the width of the product and the height of the product in this plane, potentially also including a tolerance. When the product size varies, this will result in the fin formed above the product when forming the sealing material around the product with the forming set taking different size and/or different position.
  • Controlling of the adjusting means may then encompass comparing the obtained height and/or width of the product to a preset value and then deriving, from the result of this comparison, how the forming set has to be adjusted and/or how the sealing station has to be adjusted.
  • the sealing machine further comprises a second sealing station downstream of the forming set, wherein the second sealing station is adapted to seal the sealing material along a direction that is substantially perpendicular to the transport direction and wherein the control device is further configured to control adjusting means associated with the second sealing station to adjust at least one characteristic of the second sealing station.
  • adjusting the at least one characteristic of the second sealing station may encompass adjusting a position where the sealing is applied to the sealing material with respect to a trailing edge of a product within the sealing station. This may then take into account deviations in the height and/or width of the product that may make repositioning of the cross sealing necessary.
  • the characteristic of the forming set comprises at least one of an inclination angle of at least one forming set element in a plane perpendicular to the transport direction, an inclination height of at least one forming set element, a distance of forming set elements; and/or
  • the senor comprises a height sensor for measuring a height of a product and a width sensor for measuring a width of a product.
  • the sensor may, for example, be embodied in the form of a light barrier or a camera that is adapted to determine at least one of the widths and the height of a product. It can be provided that the sensor for measuring a height of a product and the sensor for measuring the width of the product are physically distinct sensors. Alternatively, it can also be provided that these sensors are embodied in a single sensor like a light barrier or a camera that are positioned in a way so as to allow determining the width and the height simultaneously.
  • the senor comprises a camera and/or an optical barrier for measuring a height and/or a width of a product.
  • the senor is configured to measure a height and/or a width of each product and to output, for each product, a signal to the control device that is indicative of the height and/or the width of the product, and wherein the control device is configured to control the adjusting means based on each received signal.
  • the present disclosure also pertains to a method for adjusting characteristics of a sealing machine, the sealing machine comprising a transporter transporting a product along a transport direction, a forming set forming a sheetlike sealing material around the product transported through the forming set along the transport direction, and a sealing station downstream of the forming set, wherein the sealing station seals the sealing material in a direction substantially parallel to the transport direction, the sealing machine further comprising a sensor arranged upstream of the forming set and a control device, wherein the method comprises measuring, by the sensor, a height and/or a width of a product and controlling, by the control device, upon receiving a signal from the sensor that is indicative of the height and/or the width of the product, adjusting means associated with the forming set and/or the sealing station to adjust at least one characteristic of the forming set and/or the sealing station based on the signal.
  • the sealing machine further comprises a second sealing station downstream of the forming set, wherein the second sealing station seals the sealing material along a direction that is substantially perpendicular to the transport direction and wherein the control device controls adjusting means associated with the second sealing station based on the received signal to adjust at least one characteristic of the second sealing station.
  • the characteristic of the forming set may comprise at least one of an inclination angle of forming set elements in a plane perpendicular to the transport direction, an inclination height of at least one forming set element, a distance of forming set elements; and/or
  • the senor comprises a height sensor measuring the height of the product and a width sensor measuring the width of the product.
  • the height sensor and the width sensor can be implemented as a single sensor or as separate sensors, realizing determination of the relevant characteristics of the product.
  • the senor comprises a camera and/or an optical barrier measuring the height and/or the width of a product.
  • the senor measures the height and/or the width of each product and outputs, for each product, a signal to the control device that is indicative of the height and/or the width of the product, and wherein the control device controls the adjusting means based on each received signal.
  • FIG. 1 shows a schematic depiction of a sealing machine 100 that may be used in connection with embodiments of the present disclosure.
  • the sealing machine 100 may be a sealing machine for sealing products 190 that have a regular form, for example the form of a rectangular prism, a cube, a trapezoid or the like.
  • the products can be characterized by a width that is perpendicular to the transport direction T of the products in a transporting device 101 (like a chain transporter) and a height that is perpendicular to the transport plane defined by the transporting device 101. They may further be characterized by a length that is measured along the transport direction T, but this is not necessary for the present disclosure.
  • the sealing machine 100 may generally be adapted to use a sheetlike sealing material 151 that is provided by a provisioning device 105 encompassing for example a sealing material roll that is unwound by means of an unwinding device (including for example a driven unwinding rod 152) so that the sealing material is provided as a sheetlike material below the products 190.
  • a provisioning device 105 encompassing for example a sealing material roll that is unwound by means of an unwinding device (including for example a driven unwinding rod 152) so that the sealing material is provided as a sheetlike material below the products 190.
  • a forming set 102 can be arranged that allows for lifting up the free areas of the sheetlike material and wrap them around the product 190 so as to enclose the product 190 within the sealing material.
  • the forming set 102 may form a fin by opposite edges of the sealing material where this fin continuously extends along the transport direction and is positioned above the products 190.
  • a first sealing station 103 (this does not necessarily mean that it is the first sealing station downstream of the forming set 102) may seal the fin of the sealing material, by applying one or more pairs of heating rollers as will be explained further below.
  • a second sealing station 104 can be provided that applies a sealing to the sealing material (for example also by applying heat) where this second sealing is applied in a direction that is substantially perpendicular to the transport direction T.
  • the products 190 may vary with respect to their width and/or their height as will be explained further below, also the amount of sealing material that will actually be available for forming the fin by the forming set 102 will vary. Likewise, the actual position of the fin and the actual position where the cross sealing can be applied between two adjacent products may vary depending on the product dimensions.
  • a sensor 110 may be provided upstream of the forming set 102.
  • the sensor 110 may be adapted to determine at least one of the width and the height of each product 190.
  • the sensor 110 can be embodied as a light barrier comprising one or more lasers and corresponding sensors that can optically detect the laser light (like a photodetector).
  • the sensor may be realized as or may comprise one or more cameras that can obtain images of the products 190 as they are moved past the sensor.
  • the respective information obtained by the sensor 110 may then be provided in the form of a signal that is indicative of the information obtained by the sensor and may particularly be indicative of the width and/or the height of the product to a control unit 180.
  • This control unit 180 is preferably coupled to adjusting means 121, 131, 141 that are associated with each of the forming set 102, the sealing station 103 and the second sealing station 104.
  • the adjusting means 121, 131 and 141 may be controlled by the control unit 180 so as to adjust at least one characteristic of their associated component, i.e. either the forming set 102, the sealing station 103 or the second sealing station 104.
  • the adjusting means may be realized as or may comprise stepping motors that are connected to moveable components of the forming set 102, the sealing station 103 or the second sealing station 104.
  • the characteristics of the respective components can be adapted to changing characteristics of the products, particularly changing characteristics of the products with respect to the width and/or the height.
  • each product is determined with respect to its height and/or width by the sensor 110 and the control unit 180 controls the adjusting means 121, 131 and/or 141 based on the measured height and/or width of the product.
  • Figure 2 shows a view of a product 190 surrounded by sealing material 151.
  • the view presented here is along a direction that is parallel to the transport direction T.
  • the image plane depicted here is thus presenting a cross-section of the product 190 and the plane is perpendicular to the transport direction T.
  • the product has a width W and a height H.
  • the total width of the sealing material in a direction perpendicular to the transport direction and in the depicted plane may be denoted as L.
  • the sealing material can form a fin 291 having a length F. This is achieved by pushing together the two opposing edges of the sealing material, each of which thus being required to have the length F.
  • sealing of the product 190 is realized in a "drop like" manner. This means that sealing material extends from the upper surface of the product 190 in a tapered form so as to finally form the fin above the product. In this case, even further sealing material is required.
  • the total amount of which may be denoted as 2S.
  • the width L of the sealing material must be provided so as to fulfill the condition L ⁇ 2( W + H + F + S ).
  • the distance S may vary. This results in the fin 291 being positioned at different heights with respect to the transport plane depending on the height and/or the width of the product 190.
  • the width and/or the height of the product thus have influence on whether at all a fin 291 can be formed by the forming set because the forming set only folds the sealing material around the product at a specific height relative to the transport plane of the products. If there is insufficient material to bridge this distance to the forming set, a fin will not be formed.
  • the sealing station 103 will seal the fin 291 by pressing together the two opposing edges of the sealing material 151 and applying heat.
  • the second sealing station (if provided) which provides a cross sealing to the sealing material between a adjacent products in the transport direction T can only reliably apply this sealing if there is sufficient sealing material to bridge the distance of the fin to the transport plane so as to close the sealing material before and after a product.
  • control unit 180 discussed above with respect to figure 1 is preferably configured to control and actuate the adjusting means 121, 131 and 141 depending on at least one of a measured width and/or a measured height of a product so as to meet the above condition and so as to ensure that a fin that is basically positioned at a height that corresponds to the sum of H+S is reliably sealed and, before that, formed.
  • a forming set 202 as described above in relation to figure 1 is shown in relation to a product 390.
  • the forming set basically comprises two forming set elements 321 and 322. These are usually positioned in a specific height above a transport plane of the products and spaced apart by a specific width w.
  • the forming set elements 321 and 322 are further inclined so that an outer edge of the forming set is positioned at a height h that is smaller than the height of an inner edge of each of the forming set elements, where the inner edges are positioned so as to contact and form the fin 392 of a product.
  • the achievable height F of the fin may change and consequently the adjusting means associated with the forming set are preferably able to control at least one of the distance w of the forming set elements 321 and 322, the height h of the forming set elements 321 and 322 and an angle ⁇ of inclination of at least one of the forming set elements.
  • each of the forming set elements 321, 322 can be moved relative to the middle of the transport plane of the transporting device.

If the fin is positioned at a comparably low height relative to the transport plane of the products 390, the heating rollers can be lowered so as to be able to contact the fin. Alternatively, if the fin is positioned at a comparably large height relative to the transport plane of the products, the heating rollers can be lifted so as to contact the fin, but not additional the material that is placed between the top surface of the product and the actual fin 392, in the region denoted with the height S as in figure 2 . Thereby, reliable sealing is ensured.
  • the sealing station 203 depicted in figure 3b comprises a further set of tracking rollers 311. These can be provided as rollers that do not apply intentional heat to the fin 392 but apply a tensioning force to the fin 392 so as to tension the fin and reduce the distance between the opposing edges of the sealing material that actually form the fin.
