Definitions

  • the invention relates to a method for producing angular lids, which have tear-open tabs at the ends, from a film web which is cut in at least a first of its two longitudinal edges to form at least one open-cut incision, whereupon the film areas arranged on both sides of the cut-in are formed along to form the tear-open tabs one fold line each is folded back on itself and the film web is cut to length to form the cover.
  • the invention also relates to a device for producing angular lids, which have tear-open tabs at the lid corners, from a film web with a frame holding the film web, at least one cutting arrangement for cutting an open-cut incision into the film web on at least a first of its two longitudinal web edges, and with one Fold-over arrangement with a fold-over part and a separating arrangement for cutting the film web to length to form the cover, the fold-over part returning from an initial position located on one side of the film web plane while folding the film regions arranged on both sides of the cutting plane back to form the tear-open tabs in one on the other side the film web located, the tear tabs at least partially holding down end position and is movable back
  • a method and a device of the type mentioned are known. It is a machine for closing filled containers, such as menu trays, with lids, which are also produced with this machine.
  • a film web which can consist, for example, of aluminum or plastic material, passes step by step through a device for producing the cover. It consists of a cutting station, a folding station and a separating station for separating the lids. The lids are then fed to a closing station for closing the containers.
  • Each container is provided with an outwardly extending flange. After being placed on the container, the lid is folded down around this flange.
  • the dimensions of the tear-open tabs which extend over the entire length of the narrow sides of the container are such that their free end regions are arranged on the upper side of the cover after it has been folded over and are therefore easy to grasp.
  • Each cover is folded over the entire length of one of its end faces formed by the longitudinal edges of the film web, parallel to the latter, and is provided with two open-edged cuts arranged at a mutual spacing.
  • the lid thus has three tear-open tabs, by means of which it can be easily and completely detached from the container in three sections over the overall dimension of the end face.
  • the incisions are cut in the cutting arrangement during the standstill phase between two feed steps of the film web by means of two cutting arrangements in the form of pairs of knives arranged at a corresponding mutual distance.
  • the feed between two standstill phases corresponds to the length of the three pull tabs.
  • the film web cut in this way is fed to the folding station with the next feed step, in which the film regions between the incisions are folded over by means of the folding part of corresponding length.
  • a film section is cut off in the middle between two incisions, so that a cover with two tear-open tabs assigned to the cover corners and a tear-open tab located between them is created.
  • the lid production according to this known method requires relatively complex, precisely adjusted devices with a large space requirement.
  • Two knives arranged at a distance from one another and a separate folding station precisely matched in their functional elements are required solely to form the tear-open tabs, and additionally a separating station.
  • the length of a cover blank is required as the overall length and each station requires its own drive.
  • Another disadvantage is that a relatively large number of incisions per cover have to be cut and the corresponding film areas have to be folded over. Compared to the lid surface, the additional expenditure of foil material is correspondingly large.
  • two adjacent lids are provided with an oblique tear tab on each of their facing lid corners on a film web side. Only one incision is required to produce both pull tabs. Conversion to lids of other dimensions can consequently be carried out with less time and with greater accuracy, since it is only necessary to advance the film web between two standstill phases and, if appropriate, the distance between a cutting arrangement for cutting the incision and a separation arrangement for cutting the film web to length to coordinate new lid dimensions. This can be done, for example, by increasing the feed rate with the same cycle time and shifting the separating arrangement. It is not necessary to change tools. The change in distance when changing to other cover dimensions is completely eliminated if, for. B. the cutting of the film web takes place in continuation of the cutting, for example by means of the cutting arrangement adapted for this.
  • the lid By designing the Aufr Strukturlaschne as oblique tabs on the lid corners, the lid can be easily removed diagonally and over the entire surface of the container, so that the favorable tear properties of the lid manufactured with the known method and the known device are at least maintained.
  • An additional advantage results from the fact that the lid is not destroyed during detachment from the container and can therefore be handled more easily.
  • the cost of materials for the lid is also lower, since its dimensions do not have to be larger than is necessary to carry out a secure closure of the container.
  • the additional film requirement of the pull tabs according to the prior art is eliminated.
  • the film areas assigned to the incision are already folded over substantially during the incision.
  • This simultaneity of the cutting and folding process simplifies the process sequence.
  • the simultaneity of the cutting and folding process is preferably achieved in that the foil areas to be folded are held on both sides of the cutting plane of a stationary cutting arrangement for cutting the incision and are moved past the cutting arrangement in the folding direction and continuously folded over while cutting continuously.
  • the folding part has two folding edges converging in the direction of the film web at an angle in a V-shape, that the imaginary intersection of the folding edges lies in the cutting plane of the cutting arrangement, and that the separating arrangement for cutting the film web along and is formed in continuation of the incision.
  • the cutting arrangement is preferably designed as a knife which is arranged with its cutting edge on the side of the film web opposite the starting position of the folding part and is movable relative to the film web.
  • the folding part is advantageously designed as an essentially triangular-shaped plate part with two of its front edges representing the folded edges.
  • the folding part can have a slot that is open at least at its tip and runs in the cutting plane of the knife, the width dimension of which is greater than the thickness dimension of at least the area of the knife blade assigned to the knife edge.
  • a counterholder with two counterholder edges is preferably arranged at least during the folding over on the side of the film web opposite the starting position of the folding part, the counterholder edges defining a passage opening for the passage of the folding part during the folding over.
  • the folding part in its end position above the counter-holder in the division of labor assign.
  • the counter-holder can then preferably be moved from its working position into a rest position distant from the end position of the folding part after the folding process.
  • the folding part can be designed to be translatable into its end position and back from its initial position, in which the folding edges are arranged parallel to the plane of the film web. It is advantageous here to make the folding part movable from the starting position to the end position along a circular path that intersects the longitudinal edge of the film web.
  • the counter-holder can also be movable in translation and / or along a circular path, which is preferably arranged in the plane of the circular path of the folding part.
  • the functional elements for moving the folding part and the counter-holder are preferably mechanically coupled to one another and positively controlled relative to one another.
  • a film web 1 is gradually withdrawn from a supply roll 2 by means of a drive, not shown, in a horizontal plane.
  • the film web 1 passes in the conveying direction F one after the other through a cutting and folding station and a separating station 3, in which the film web 1 is cut to length in order to produce covers 4.
  • the lid 4 can then be fed to a closing station, not shown, for closing filled containers.
  • the cutting and folding station consists of two cutting and folding arrangements 5, 6, one of which is assigned to a first longitudinal edge 7 of the film web and the other to the opposite longitudinal edge 8 of the second film. Both arrangements 5, 6 are identical to one another. Their corresponding components are therefore designated by the same reference numerals.
  • Each cutting and folding arrangement 5, 6 each has a cutting arrangement 9 and a folding part 10. Both knives 9 each cut a not open edge not shown here into the film web 2 in a manner to be described. Both incisions lie on a normal to the film web longitudinal edges 7, 8, d. H. these right-angled straight lines.
  • each incision The film areas 11 arranged on both sides of each incision are folded back on themselves in a manner to be described again by means of the folding parts 10, the folding lines running obliquely from the respective longitudinal edge 7 or 8 of the film web to the end of the respective incision, as in FIG Fig. 1 shown.
  • the separation station 3 the film web 1 along and in continuation of the incisions, d. H. cut to length along their connecting straight lines, so that each lid is provided with a triangular pull tab at each of its corners.
  • the cutting and folding arrangements 5, 6 are shown in detail. Since both are identical to one another, the arrangement 5 assigned to the first longitudinal edge 7 of the film web (on the left in FIGS. 2 and 3) is described below.
  • a support plate 13 for supporting the film web 1 is arranged below it.
  • the cutting arrangement 9 is designed as a knife, more precisely as a knife blade, which is received in a clamp holder 14 fastened to the frame 12. Both knives 9 are arranged in a common knife or cutting plane ME above the film web 1 and this is approximately half projecting.
  • the knife plane ME runs perpendicular to the film web 1.
  • the folding part 10 is plate-shaped and has at its end facing the film web 1 an isosceles triangular attachment, one tip of which is arranged in the knife plane ME and the front edges of which are V-shaped in the direction of the tip represent the folding edges 15 of the folding part 10.
  • the folding part 10 is divided over its entire length by a slot 16 into two symmetrical folding part halves 17. The width of the slot 16 is slightly larger than the thickness of the knife blade 9.
  • the folding part 10 can be moved from an initial position A shown in FIGS. 2 and 5 into an end position E shown in FIGS. 4 and 9. In the starting position A, the folding part 10 is located approximately parallel to the film web 1 below it.
  • the movement of the folding part 10 from the out Starting position A in the end position E takes place diagonally upwards in the direction of the center of the film web.
  • the two halves of the folding part 17 grasp the assigned film areas 11 and fold them upwards, the knife 9 dipping into the slot 16 cutting the incision in accordance with the progress of the folding process. Strictly speaking, the incision always precedes the folding process, since otherwise the film web 1 would not be cut but torn.
  • the folding part In the end position E, the folding part is in a position closer to the center of the film web, approximately parallel to the film web 1 above it, and holds down the folded film regions 11.

  • the end edges of the counter-holder 19 which define the passage opening 20 and converge in the apex 21 represent its counter-holder edges 22 which, in cooperation with the folding part 10, determine the folding lines of the tear-open flaps 11. In other words, the folding part 10 folds the film areas 11 to be folded over the counter-holder edges 22.
  • the apex 21 of the counter-holder 19 is in the working position AR below the end of the knife 9 inside the film web, and the counter-holder edges 22 run at the same angle as the folding edges 15 of the folding part 10 up to at least the respective film web longitudinal edge 7 or 8.
  • the folding part 10 passes through the opening 20 with play during folding.
  • the circular path described by the folding part 10 - in particular its folding edges 15 - around the crank bearing 30 or 93 passes through an apex position and, when it is subsequently lowered, causes the folded-over film areas to be pressed onto the counter holder 19.
  • the folding part 10 is arranged above the counter holder 19 after the folding process has ended . After folding over, in order to enable the stepwise advancement of the film web 1 in the conveying direction F, the counter-holder 19 is moved from its working position AR (see FIGS. 4 and 9) into a rest position R (see FIGS. 2 and 5).
  • the frame 12 comprises on both sides of the film web 1 a vertical frame section 231, 232 which are connected at their upper ends by a horizontal bridge section 23 spanning the film web 1 and at their lower ends by a frame bar 233.
