Definitions

  • the invention relates to a device for automatically closing rosette closures on boxes, with fingers for bending the closure tabs inwards and with a stamp for depressing all closure tabs into their stable closed position.
  • a known device of this type according to NL-OS 7 401 306 has, in a first station, a ring of curved fingers which are firmly connected to a carrier and which overall lie approximately on a conical surface. These fingers are moved towards the closing flaps of the open box with simultaneous rotation and, in a first step, are intended to cause pre-breaking along weakened lines between adjacent closing flaps.
  • a cone is initially moved towards the locking flaps in order to bend these locking flaps inward by approximately 45 °, whereupon an axially moved plunger grasps the locking flaps and presses them into their stable closed position.
  • This known device requires no less than three organs which can be actuated independently of one another, the one of these organs, namely the ring of fingers, at the same time having to be axially moved and rotated in the preliminary breaking station.
  • the station is therefore cumbersome and complex.
  • Preliminary breaking using a rotating ring of fingers proves to be difficult to carry out in practice, among other things because the sealing flaps are easily deformed or damaged by the rotating fingers, which then leads to unsightly boxes.
  • this is all the more disadvantageous as boxes with rosette closures are in themselves quite complex and are therefore only used for packaging valuable goods.
  • the aim of the invention is a device to create, which is not only much easier to set up, but also allows a more careful handling of the box when closing.
  • This goal is achieved in that a finger is assigned to each closure flap and that all fingers are pivotably arranged on a support which can only be moved axially, in such a way that each finger is moved axially with a radial inward movement.
  • the box can basically be closed in a single station and only two different organs, namely the carrier mentioned and the plunger, can be given a simple axial movement.
  • the fingers are not subject to a rotary movement, but after the closure flaps have been gripped at their outer end, they are simultaneously moved axially towards the box and pivoted radially inwards, so each finger slides approximately lengthways over the closure flap assigned to it, which is gentle treatment and secure closure guaranteed.
  • the fingers preferably each have an inwardly directed, free end with a contact edge of a certain length, with the result that this contact edge engages the associated closure flap over a certain width and not only locally or along a line and could thus deform or damage it .
  • a second station with fingers of the same type can be provided, which serves to break the weakened lines between adjacent flaps.
  • a sensor can preferably also be provided, which is inserted into the still open box to determine the presence and correct position of the chess to check the content of the This sensor can be designed as a plate or plate to hold down or push down the contents of the box and at the same time to keep the container stable during the pre-crushing process.
  • a hexagonal box 1 with an already shaped, flat bottom is shown.
  • a conveyor device namely a conveyor chain with holders 3 is indicated, by means of which boxes 1 can be conveyed one after the other over a fixed guide rail 2 under the closing device.
  • a control cone 6 is fastened to a frame part 4 of this device by means of a hollow rod 5.
  • a plunger 7 is axially displaceable.
  • a sleeve 8 is axially displaceable, the movement or position of which is determined by a control rod 9. The movements of the plunger 7 and the rod 9 or the sleeve 8 are controlled by a central camshaft.
  • the sleeve 8 has a flange 10 with which C-shaped yokes 11 are screwed.
  • the parts 8 to 11 form a support for six fingers 12, which are mounted in the yokes 11 so as to be pivotable about axes 13.
  • Springs 14 always seek the fingers 12 radially outward with their lower end Sen to pivot or to put the upper finger end with the control roller 15 against the control cone 6.
  • plates 16 are fastened, the inner, rounded edges 16a of which are intended to be placed against one of the closing flaps 17 of the box 1.
  • the carrier 8, 10, 11 with the fingers 12 is at the beginning of each working cycle in an upper end position in the stop on the frame part 4. In this position, the control rollers 15 of the fingers 12 are lifted off the control cone 6 and the fingers are spread a little further. With this position of the parts, a new box 1 can be brought under the closing device with the conveying device, while a previously closed box is removed. If the box is in the working position according to FIG. 1 coaxially under the closing device, the carrier 8, 10, 11 is lowered with the fingers 12 and reaches the position according to FIG. 1, in which the control rollers 15 have just run onto the control cone 6 and the Fingers are increasingly pivoted with their lower ends inward during the further downward movement.
  • edges 16a of the plates 16 each meet a sealing tab 17, and these edges lie on the flat sealing tab 17 over their entire length.
  • Each finger then begins to press the associated closing flap 17 inwards, lines 18 weakened by perforation breaking inwards and the triangles 19 being pivoted inwards about the folding lines 20. All parts 17 and 19 are pushed inwards relative to the axial position shown in FIG. 1 and finally reach a position as shown in FIG. 2, in which the edges 16a of the plates 16 move continuously downwards and inwards as far as the lower end of the associated locking tabs 17 have reached and placed them overlapping each other inside. From the position shown in solid lines in FIG.
  • the locking tabs can now be pressed downward by lowering the plunger 7 into the dash-dotted position into the stable position, also indicated by dash-dotted lines.
  • the closure is thus created and the plunger 7 and the carrier 8, 10, 11 with the fingers 12 can be moved upwards from the lower end position shown in FIG. 2 to their upper end position.
  • the closed box 1 is now conveyed away by means of the conveying device and a new open box is brought under the device shown for closing.
  • a closing station according to FIGS. 1 and 2 is sufficient for the relatively slow closing of rosette closures.
  • Such a device can therefore advantageously also be used for the semi-automatic closing of boxes in manual operation, the boxes being placed under the device by hand and the closing device being operated at a suitable speed in the manner mentioned.
  • the locking device according to FIGS. 1 and 2 can of course also form part of a fully automatic packaging and locking system.
  • the closing station according to FIGS. 1 and 2 is preferably preceded by a preliminary breaking station according to FIG. 3, which is constructed similarly to the closing station. It also has a bushing 8 with flange 10 and yokes 11 screwed to it, to which fingers 12 are pivotally attached.
  • the plates 16 of the fingers 12 are flat.
  • the control cone 6 ' is also designed somewhat differently than that according to FIGS. 1 and 2.
  • a plate 21 is provided, which is attached to a vertically displaceable rod 22. He is dimensioned so that it can be inserted into the open box with little play.
  • FIG. 3 shows an operating position in which the fingers 12 will soon hit the closing flaps 17 in order to bend them inwards.
  • the plate 21 is lowered onto the box contents 23 indicated in FIG. 3 and, if necessary, pushes it down a little so that it does not in any way hinder the later flipping of the closure flaps 17 into the somewhat inwardly inclined, stable position.
  • the insertion of the plate 21 can be used for some control. If it is not possible to lower the plate 21 sufficiently because the box is overfilled or the box contents are jammed in the box, this defect can be indicated and / or the subsequent closing process can be omitted in order to avoid damage to the box contents or the closing device.
  • a presence check can also be carried out, in that if the plate 21 is lowered too far, it is assumed that the box contains no or insufficient content, and the box can be removed.
  • the plate 21 inserted into the upper end of the box also has a stabilizing effect on the box when the fingers 12, 16 strike the closing flaps 17 and press them inwards to break the perforated lines 18.
  • both the carrier 8, 10, 11 with the fingers 12 and the plate 21 are quickly raised into an upper rest position and the box is now conveyed into the station according to FIGS. 1 and 2, where the final sealing he follows.
  • FIGS. 1 and 2 Different variants are possible. It would be conceivable equip a single existing station according to FIGS. 1 and 2 with a plate 21 instead of a simple plunger 7, the design of which has both functions, namely that of leveling and scanning the contents of the package and stabilizing when breaking in and then finally closing it by pressing the closure flap into it inward inclined, stable closing position could serve. This possibility may depend somewhat on the type of box content. But it would also be possible to arrange a plate 21 and a plunger 7 coaxially one inside the other and separately operable, in which case a single station could take over all the functions of the two stations described in FIGS.
