Definitions

  • the invention generally relates to ice cream production, and in particular to a multi-lane system for wrapping ice cream products and a method thereof.
  • a multilane wrapper such as Tetra Pak ® Multilane Wrapper A2 marketed by Tetra Pak.
  • the multi-lane wrapper provides for that sandwiches, bars, cones or other ice cream products can be continuously wrapped.
  • the ice cream products can be fed to the multi-lane wrapper from a dip and transfer unit, in which the ice cream products can have been provided with an outer layer of e.g. chocolate, a rotary moulder extractor, in which the ice cream products have been formed, or similar processing unit.
  • the wrapper the ice cream products are placed in lanes and from these lanes fed onto webs of packaging material. Once placed on the webs, these are folded and sealed such that longitudinal sealings are obtained.
  • transversal sealings also known as cross sealings, are formed.
  • wrapped ice cream products are formed by cutting the webs in the transversal sealings.
  • the multi-lane wrapper comes with a number of advantages. For instance, several lanes in parallel provide for high capacity, but also that different lanes may be handled individually, e.g. by controlling the cutting of the webs individually. A further advantage is that operation of the multi-lane wrapper may be synchronized with other equipment in the production line to ensure a reliable overall operation.
  • Another object may be to provide improved flexibility in terms of set-up such that the multi-lane wrapper or the ice cream production line as a whole can be adapted to meet premises-specific conditions.
  • a further object may be to provide improved working conditions for operators of the multilane wrapper.
  • a multi-lane system for wrapping ice cream products comprising reel holders for receiving reels holding webs of packaging material, a wrapping machine arranged to receive the ice cream products, to receive the webs, to enclose the ice cream products in the webs and to seal the webs such that wrapped ice cream products are formed, and a web conveying arrangement arranged to individually feed the webs of packaging material from the reels to the wrapping machine, wherein the web conveying arrangement comprises de-tensioning devices arranged to decrease tensions in the webs upstream the wrapping machine.
  • An advantage of having de-tensioning devices upstream the wrapping machine is that the webs that enter the wrapping machine can have a tension that provides for that forming of wrapped ice cream products in the wrapping machine can be made with less risk of web-rupture, which in turn provides for less down time for the multi-lane system.
  • the web conveying arrangement may comprise first sliders placed downstream the reel holders and upstream the de-tensioning devices, wherein the first sliders are angled relative to a first feeding direction FD1 of the webs, such that the webs are turned and redirected from the first feeding direction FD1 to a second feeding direction FD2 when slid over the first sliders.
  • the system may be L-shaped, or U-shaped if additional sliders are provided. This has shown to provide efficient feeding of the web to the wrapping machine as well as to offer more operator-friendly handling of the reels.
  • the web conveying arrangement may comprises second sliders placed downstream the de-tensioning devices and upstream the wrapping machine, wherein the second sliders are angled relative to the second feeding direction FD2, such that the webs are turned and redirected from the second feeding direction FD2 to a third feeding direction FD3 when slid over the second sliders.
  • the second sliders can in combination with the first sliders provide for that the system is U-shaped. This makes the handling of the reels easier for an operator.
  • the first sliders may be elongated and extend in parallel to a first axis A1 that is angled by 30° to 60° relative to the first feeding direction FD1
  • the second sliders 116 are elongated and extend in parallel to a second axis A2 that is angled 30° to 60° relative to the second feeding direction FD2.
  • the reel holders may be placed at a horizontal distance HD of at least 1 meter from the wrapping machine, and the reel holders may be placed at a vertical distance VD of at least 0.5 meter from a floor level.
  • the reel holders may comprise a first group of reel holders arranged for receiving a first set of reels from a first side S1, and a second group of reel holders arranged for receiving a second set of reels from a second side S2, wherein the first set of reels may be arranged to feed out first webs in a first plane P1 and the second set of reels may be arranged to feed out second webs in a second plane P2, wherein the first and second planes P1, P2 may be parallel vertical planes.
  • the de-tensioning devices may be placed in a third plane P3, wherein said third plane P3 is a vertical plane.
  • the second sliders may be horizontally displaced, such that the webs can be horizontally displaced when fed to the wrapping machine.
  • Each de-tensioning device of the de-tensioning devices may comprise a roller that is arranged to be rotated by a motor giving the roller a peripheral speed that is higher than a speed by which the web passes the roller.
  • the webs of packaging material may comprise polypropylene PP.
  • a method for wrapping ice cream products comprises providing webs of packaging material from reels placed on reel holders, conveying the webs individually from the reels to a wrapping machine by using a web conveying arrangement, decreasing tensions in the webs by using de-tensioning devices, feeding the webs into the wrapping machine, feeding the ice cream products into the wrapping machine, enclosing the ice cream products in the webs, and sealing and cutting the webs such that wrapped ice cream products are formed.
  • an advantage with decreasing tensions in the webs using de-tensioning devices is that the webs that enter the wrapping machine can have a tension that provide for that forming of wrapped ice cream products in the wrapping machine can be made with less risk of web-rupture, which in turn provides for less down time for the multi-lane system.
  • the method may further comprise turning and redirecting the webs from a first feeding direction FD1 to a second feeding direction FD2 by sliding the webs over first sliders.
  • the method may further comprise turning and redirecting the webs from the second feeding direction FD2 to a third feeding direction FD3 by sliding the webs over second sliders.
  • the method may further comprise displacing the webs horizontally while turning and redirecting the webs using the second sliders.
  • the step of decreasing the tensions of the webs using the de-tensioning devices may comprise, for each de-tensioning device, rotating a roller by a motor such that a peripheral speed of the roller is higher than a speed by which the web passes the roller.
  • Fig. 1a and 1b illustrate a multi-lane system 100 for wrapping ice cream products by way of example.
  • reel holders 102 can be provided for receiving reels 104 holding webs 106 of packaging material.
  • a web conveying arrangement 108 which may comprise several rollers and motors, the webs 106 can be fed into a wrapping machine 110 in which ice cream products are wrapped in the packaging material.
  • the multi-lane system 100 can have a U-shaped form, seen from above, such that the reel holders 102 and reels 104 can be placed at a horizontal distance HD from the wrapping machine 110.
  • the U-shaped form makes the multi-lane system 100 different from other multi-lane wrappers. Unlike the multi-lane system 100 illustrated in fig. 1a , it is namely common practice for other multi-lane wrappers to have the reel holders placed below the wrapping machine 110.
  • the multi-lane system 100 may have an L-shaped form.
  • An advantage of having the reel holders 102 placed offset is that more room can be provided to an operator such that the reels 104 can be replaced more conveniently.
  • de-tensioning devices 112 are provided. Since conditions may vary for different webs 106, the de-tensioning devices can be handled individually, thereby assuring that each web is de-tensioned appropriately such that problems that may be caused due to incorrect tension in the wrapping machine 110 can be avoided.
  • the webs 106 can be redirected twice. These redirections can be achieved by using first sliders 114 placed downstream the reel holders 102 and upstream the de-tensioning devices 112, and by using second sliders 116 placed downstream the de-tensioning devices 112 and upstream the wrapping machine 110.
  • the first and second sliders 114, 116 may be elongated elements that may be made in metal, e.g. cylindrically shaped metal elements. Surfaces of the first and second sliders 114, 116 may be treated such that low friction coefficients are provided, thereby providing for that the webs 106 can be slid over these without damaging printed pattern of the webs 106 or unduly upholding the webs.
  • the reel holders 102 may be provided at a vertical distance VD from a floor level 118.
  • the vertical distance may be measured from the floor level 118 to a center of the reel holder that is closest to the floor level.
  • An advantage with having the reel holders 102 placed in this way is, for example, that the reel holders 102 can be provided at an appropriate working height for the operator such that ergonomically correct working positions can be offered.
  • the reel holders 102 may be provided at two rows. Another option is to have the reel holders provided in one and the same row. Still an option is to have more than two rows. One reason for having a plurality of rows is that a more compact design can be achieved.
  • the reel holders 102 may be provided on two different sides, herein referred to as a first side S1 and a second side S2.
  • a first side S1 a first group of reel holders 120a configured to hold a first group of reels 122a can be provided.
  • a second group of reel holders 120b configured to hold a second group of reels 122b can be provided.
  • the first group of reel holders 120a and the first group of reels 122a that can be placed in one or several rows, can be provided in a first plane P1 and the second group of reel holders 120b and the first group of reels 122b can be placed in a second plane P2.
  • the first and second plane P1, P2 can be vertical planes and, also as illustrated, the first and second plane P1, P2 can be parallel.
  • first and second webs 124a, 124b When passing the first sliders 114, first and second webs 124a, 124b, fed from the first and second group of reels 122a, 122b, respectively, can be redirected, turned and brought into one and the same plane, a third plane P3 (see also fig. 2 ).
  • the first and second webs 124a, 124b may be fed from the first or second plane P1, P2 into the third plane P3.
  • the first and second plane P1, P2 may be placed perpendicular to the third plane P3, and the first sliders 114 may be angled 45 degrees relative to the first and second plane P1, P2.
  • An advantage of having the reel holders 102 placed in the first and second plane P1, P2 is that access to the reel holders 102 can be provided via both the first side S1 and the second side S2.
  • One reason for having the first and second web 124a, 124b coinciding in the third plane P3 is that de-tensioning devices 112 may be provided in the same vertical plane. Put differently, as illustrated, the de-tensioning devices 112 may be placed above each other, which provides for that these can be easily inspected and adjusted by the operator.
  • each of the de-tensioning devices 112 can comprise a roller 126, a passive roller 128 and a motor 130.
  • the roller 126 may be controlled by the motor 130 such that the roller 126 can be given a peripheral speed that is higher than a speed by which the web 106 passes the roller 126.
  • This in combination with the passive roller 128, that is not controlled by the motor 130, provides for that a tension of the web 106 can be reduced, which in turn provides for that the webs 106 can be fed into the wrapping machine 110 and handled with low risk of failure in the wrapping machine 110.
  • Each web 106 may be controlled individually such that the tensions may be decreased individually. This may be achieved by have a dedicated motor for each web. Another option is to use the same motor for a plurality of webs, thereby collectively decrease the tensions in a plurality of webs.
  • the plurality of webs may comprise all webs 106 or a sub-set of the webs 106.
  • Fig. 2 schematically illustrates a multi-lane system 100, such as the multi-lane system 100 described in connection with fig. 1a and 1b .
  • the multi-lane system 100 of fig. 2 may include the same features as the multi-lane system illustrated in fig. 1a and 1b , and vice versa.
  • the multi-lane system 100 of fig. 2 has reel holders 102 which are provided in the first group of reel holders 120a and the second group of reel holders 120b such that these can be accessed via the first and second side S1, S2.
  • the first group of reels 122a provided on the first group of reel holders 120a, feed out the first webs 124a in the first plane P1 in a first feeding direction FD1.
  • the second group of reels 122b provided on the second group of reel holders 120b, feed out the second webs 124b in the second plane P2 in the first feeding direction FD1.
  • four reels 104 are provided, two on each side, resulting in that the first webs 124a comprise webs in two rows, and also that the second webs 124b comprise webs in two rows.
  • the first sliders 114 may be horizontally displaced. Further, to provide for that the first and second webs 124a, 124b are redirected, the first sliders 114 may be elongated and extend in parallel to a first axis A1 that is angled 30-60° relative to the first feeding direction FD1.
  • the first axis A1 is angled 40-50° relative to the first feeding direction FD1. More preferably, the first axis A1 is angled 45° relative to the first feeding direction FD1, as illustrated in fig. 2 , such that a second feeding direction FD2, that is, a feeding direction downstream the first sliders 114 and upstream the second sliders 116, is perpendicular to the first feeding direction FD1.
  • the second sliders 116 may be displaced horizontally to provide for that the first and second webs 124a, 124b provided in the third plane P3, that is, one and the same vertical plane, can be re-arranged such that these are placed in a fourth plane P4, that is, one and the same horizontal plane. This provides for that the webs 106 can be fed into the wrapping machine 110 next to each other, which is advantageous e.g. in that this provides a good overview for the operator.
  • the second sliders 116 also provide a redirection of the first and second webs 124a, 124b.
  • the second sliders 116 may be elongated and may extend in parallel to a second axis A2 that is angled 30-60° relative to the second feeding direction FD2.
  • the second axis A2 is angled 40-50° relative to the second feeding direction FD2.
  • the second axis A2 is angled 45° relative to the second feeding direction FD2, as illustrated in fig. 2 , such that a third feeding direction FD3, that is, a feeding direction downstream the second sliders 116 and upstream the wrapping machine 110, is perpendicular to the second feeding direction FD2.
  • ice cream products 202 may be placed on the webs. Inside the wrapping machine 110, longitudinal sealings and transversal sealings can be formed and the webs may be cut into wrapped ice cream products 204 that are fed out from the wrapping machine 110.
  • Fig. 3 is a flowchart illustrating a method 300 for wrapping the ice cream products 202.
  • a first step 302 the webs 106 of packaging material from the reels 104 placed on the reel holders 102 can be provided.
  • the webs 106 can be individually conveyed from the reels 104 to the wrapping machine 110 by using the web conveying arrangement 108.

  • the ice cream products 202 can be enclosed in the webs 106.
  • the webs 106 can be sealed and cut such that the wrapped ice cream products 204 can be formed.
  • the second step 304 may comprise a first sub-step 316 in which the webs 106 are turned and redirected from the first feeding direction FD1 to the second feeding direction FD2 by sliding the webs 106 over first sliders 114, which may be elongated and extend in parallel to a first axis A1 that is angled by 30° to 60° relative to the first feeding direction FD1, preferably 40° to 50°, more preferably 45°.
  • the second step 304 may comprise a second sub-step 318 in which the webs 106 are turned and redirected from the second feeding direction FD2 to the third feeding direction FD3 by sliding the webs 106 over the second sliders 116, which may be elongated and extend in parallel to a second axis A2 that is angled 30° to 60° relative to the second feeding direction FD2, preferably 40° to 50°, more preferably 45°.
