Definitions

  • the invention relates to a method for closing a container with a lid, the former having a container flange facing outside the container and the latter having a lid edge protruding beyond the container flange, and the container and lid being made of plastically deformable material, preferably aluminum foil, the container either with a lid that is prefabricated, or a flat lid blank inserted on slide rails above the container between one.
  • the upper part and a lower part of a closing device brought into contact with the upper part by at least a part of the lid surface with a vertical relative movement of the lower and upper part, the lid edge bent by frame elements mounted horizontally displaceably on the upper part in the direction of the container bottom, bent under the container flange. and is pressed with the container flange.
  • the invention further relates to an apparatus for performing the method described above.
  • the receptacle for the container is designed here as a stationary support plate which laterally fixes the container bottom and the adjacent part of the lower container wall by means of an upwardly bent edge.
  • the upper part and the lower part are both designed to be vertically movable.
  • the counter pressure surface is mounted so that it can move vertically within the upper part and is arranged at the beginning of the closing process below the upper part to leave this free. To carry out the closing process, the upper part is lowered until the counter pressure surface lies on the container or the lid.
  • the support of the container on its container base requires the precise adjustment of the stroke of the Upper part to prevent the container from being squashed by lowering the upper part too far.
  • Another disadvantage is the necessity that the support plate, the lower part, the frame elements and the counter pressure surface have to be replaced when changing to a different type of container.
  • this is achieved in that the container is received by a supporting edge of the lower part on the underside of the container flange at least in its inner edge area assigned to the container wall and with at least one part of the lid assigned to at least partial areas of the container flange by vertical movement of the lower part of a zero position past aa the frame elements is brought up to an upper pressing position for contact with the upper part, the lid edge being bent by passing the frame elements, and by moving the frame elements until support of an outer edge area of the container flange including the corresponding partially bent lid edge area the container is held in contact with the upper part, then the container flange from the supporting edge by vertical movement of the lower part past the frame elements in the direction of the lower zero position released and the lid edge by further displacement of the frame elements to a front end position is bent so far that it moved again by pushing the frame elements back to a rear end position up to at least the upper pressing position, the container from the frame elements and continue completely bent in contact with the upper part holding the upper part and pressed with the container f
  • the support edge serves both as a receptacle and as a pressure surface, forces which occur when the edge of the cover is bent or bent are absorbed by the support edge and not by the edge of the cover. Deformations in the container flange cannot lead to incorrect bending and bending as before, but are compensated for by the supporting edge.
  • the correct bending of the edge of the lid required for a secure closure is promoted in that the supporting edge is lowered again after reaching the upper pressing position for the first time, in order to enable horizontal displacement of the frame elements as far as possible in the direction of the container wall. After the end of the bending of the lid edge and retraction of the frame elements, there is a renewed upward movement of the support edge for pressing the lid edge.
  • the container or container flange in contact with the upper part continues during the period in which the supporting edge moves away from the upper part from the frame elements held in systems on the upper part, the transfer from the support edge to the frame elements and back in a "flying" manner.
  • DE-OS 31 24 733 discloses a closing device for closing the containers mentioned at the outset, which has a stationary upper part and a vertically movable lower part with an edge-shaped pressure surface assigned to the counterpressure surface in the upper part.
  • the closing process takes place in a manner unrelated to the species with an exposed cover, i.e. ' . without positive retention of the lid edge on the top of the container flange by means of the counter pressure surface of the upper part.
  • a support plate is provided between the upper and lower part, onto which the container to be closed is placed.
  • a horizontally movable one is used to close the container.
  • the container can be closed even more securely in that the lid edge with the container flange by moving the lower part up to is pressed into a re-pressing position arranged above the upper pressing position.
  • Container flange is released from the support edge by moving the lower part past the frame elements into a central zero position arranged above the lower zero position.
  • the object is achieved with respect to the device in that the upper part is designed to be stationary in the vertical direction, the vertically movable lower part has a support edge designed as a receiving and pressure surface for at least the inner edge region of the container flange or the associated lid edge associated with the container wall.
  • the design effort of the device according to the invention is reduced by using a lower part, which takes over both the function of the container receptacle and that of the pressure surface.
  • a further design simplification results from the fact that only the lower part is designed to be vertically movable.
  • the supporting edge is preferably designed in such a way that it lies at least partially against the outer wall of the container. This results in a particularly precise lateral fixation of the container.
  • An advantageous development of the invention is. characterized in that the lower part in an upper pressing position for bending the edge of the lid and for applying at least a part of the lid surface assigned to the supporting edge to the counterpressure surface and from the upper pressing position towards the lower zero position for flying takeover of the container and holding it in contact with the upper part and for bending the lid edge through the frame elements and finally again into the upper pressing position with flying takeover of the container in contact with the upper part and released by the frame elements is designed to be movable with the container flange for pressing the edge of the lid.
  • the part is favorable to lower the part into a position above the upper pressing position. arranged arranged repressing position to be movable.
  • the lower part is advantageously designed to be movable from the upper pressing position to a middle zero position arranged above the lower zero position.
  • the lower part and the frame elements are moved by means of a common drive device. This creates the prerequisite for a forced control of the vertically and horizontally movable parts.
  • the drive device preferably has a toggle lever, one outer joint of which is connected to the lower part and the other outer joint of which is fixed, the toggle lever extending from an extended one that determines the upper pressing position Position can be moved in one direction up to the respectively deflected position, the position determining the lower zero position and in the other direction up to a deflected position determining the middle zero position MN.
  • the supported outer joint of the toggle lever is preferably designed as an eccentric joint.
  • the positive control of the frame elements is achieved in a simple manner in that the movement of the toggle lever is transmitted to the frame elements by means of a lever arrangement.
  • the closing device comprises a frame with two support columns 7 and 8 arranged opposite one another.
  • a fixed upper part 9 is attached to the upper area of the frame connecting the support columns.
  • a lower part 10 is arranged, which by means of the bottom or at the bottom Part of the frame supported drive or guide columns 11 is vertically movable.
  • the lower part 10 is basket-shaped and has a circumferential wall 13 which extends from the basket bottom 12 upwards and serves as a supporting edge for the container 1.
  • the latter is inserted into the lower part 10 in such a way that it is connected to the inner edge region of the container wall 4
  • Container flange 5 rests on the top of the support edge 13 -
  • the container wall preferably lies at least partially on the inside of the support edge 13 for precise lateral fixing of the container 1.
  • the distance between the bottom 12 and the top of the support edge 13 corresponds to the maximum container height in order to be replaced to avoid the lower part 10 when switching to containers of different heights.
  • the upper region of the outside of the support edge 13 is designed to be slightly conical in the direction of the inner cavity of the lower part.
  • a counter pressure frame 14 having a counter pressure surface is interchangeably arranged on the upper part 9.

  • the area of the counter-pressure frame 14 assigned to the supporting edge has a substantially hemispherical shape.
  • the groove 17 is not completely filled by the support edge 13, so that a radially outer part of the groove 17 remains free for receiving the rolled edge 6 of the container 1
  • FIG. 2 shows a top view of four frame elements 16, which describe an essentially rectangular area corresponding to the projection of the cavity of the lower part 10.
  • Each frame element 16 is in each case assigned to a corner of this area, for this reason it is formed at right angles in the plan view and is displaceably mounted in the diagonal direction of this area by means of longitudinal bearings 18.
  • a turntable 19 is arranged above the upper part 9, which is made to oscillate by a pendulum axis 20 which is arranged within the support column 7 in such a way that it can oscillate .
  • the turntable 19 is in turn articulated by means of four articulated connecting rods 22 with connecting rods 23, which are arranged within the longitudinal guides 18 and transmit their longitudinal movement to the edge elements 16.
  • FIG. 3 shows a drive device 24 common for the vertical movement of the lower part 10 and the horizontal movement of the edge elements 16. It essentially comprises a driven crank 25, which is articulated via a coupling rod 26 to the central joint 27 of a toggle lever 28.

  • Figure 4 shows the locking tools, i. H. the support edge 13, the counter-pressure frame 14 and one of the frame elements 16 in the open position of the closing device.
  • the frame element 16 has assumed the rear end position HE.
  • the support edge is in a lower zero position, not shown here.
  • the lid edge 32 is in contact with the frame element 16 which is advanced from its rear end position HE in the direction of the support edge 13 and is thereby bent downwards in the direction of the container bottom 3.
  • FIG. 6 shows the support edge 13 and the frame element 16 in a position moved further upwards or inwards.
  • the lid 2 is just in contact with the counter-pressure frame 14, the rolled edge 6 of the container flange 5 having penetrated so far into the channel 17 that it is located in a plane above the frame element 16.
