Definitions

  • the invention relates to a method of assembling a bottom or cover on a box body, by internal roll; it also relates to an assembly machine capable of carrying out this process.
  • the invention overcomes these drawbacks by proposing a new method of assembling the bottom or cover on the box body, resulting in internal crimping without a protruding bead at the periphery of the corresponding end of the box.
  • the basic idea of the invention consists in using a preformed rolled edge on said bottom or cover as a bearing or reaction surface, during the internal rolling of the extreme portion of the box body.
  • the invention also relates to a machine for assembling a box body and a bottom or cover, characterized in that it comprises at least one rolling die inside which a defined rolling surface is arranged. along a predetermined perimeter, depending on the shape of the box body, this matrix comprising a socket or the like defining a first part of the rolling surface, radially inward and jaws arranged along this predetermined perimeter, that these jaws are mounted movable inside said sleeve and movable in the direction of the internal wall thereof, these jaws being shaped to define, at least partially, a second part of the rolling surface radially outward , extending said first part in a position close to said jaws and said inner wall of said sleeve, and in that said rolling die comprises te gripping means capable of retaining a bottom or cover.
  • This machine mainly consists of a drum 14 rotating around its main axis 15 for the sequencing of the different operations and here carrying four assembly assemblies 16 each comprising a rolling die 18 and a piston 19.
  • the four assemblies are regularly arranged at the periphery of the drum and angularly offset by 90 ° with respect to each other.
  • Each rolling die 18 comprises a socket 20 in the general shape of a bell, housing jaws 21, which can move radially under the action of a pusher 22 having a bearing section of varia ble axially and movable along an axis parallel to arrow A ( Figure 8).
  • the sleeve 20 has a circular lower opening while the jaws 21 are arranged regularly circumferentially inside said sleeve, the bearing section variable being here a frustoconical bearing 26. It goes without saying, however, that these shapes are dictated only by that of the crimping contour.
  • the arrangement of the jaws and the shape of the pusher may be significantly modified without departing from the scope of the invention, the necessary structural modifications being within the scope of the skilled in the art.
  • the rolling surface is distributed in the matrix 18 between the internal surface of the sleeve 20, in the vicinity of its lower opening and of the surface portions of the jaws 21. More precisely, the sleeve 20 defines a first part 20a of the surface of rolling, progressively extending radially inwards from the edge of its opening and having a suitable curved radial profile, while each jaw 21 has a curved profile surface 2la extended at its lower part by a small protruding bead 25.
  • the set of surfaces 21a thus forms a second part of the rolling surface, circumferentially discontinuous, generally oriented towards the outside and extending said first part 20a of this rolling surface when said jaws are brought closer to the internal wall of said sleeve, under the action of pusher 22.
  • Each rolling die 18 is disposed above a piston 19, the axis of symmetry of which is aligned with the axis of the pusher.
  • This piston is shaped to receive a box body 13, vertically, that is to say with an axial end of said box body resting on the upper surface of the piston. To this end, it is provided with a slight relief 31 in the form of a disc, the diameter of which corresponds to the internal diameter of the box body.
  • the piston is movable along the actuating axis of the pusher, that is to say here vertically. More specifically, the drum 14 mainly comprises two horizontal plates 33 and 34 spaced from one another and separated by a cylindrical part 36 of smaller diameter.
  • the lower plate 34 houses the pistons 19 in corresponding bores, and the lower faces of these pistons open from the lower face of the plate in order to be able to meet a lifting ramp 40, fixed, or a similar actuation means.
  • the upper plate 33 carries the dies 18 aligned with the pistons 19.
  • the cylindrical part 36 is provided with lateral recesses 37, semi-cylindrical, of shape and size suitable for receiving and driving bodies of boxes 13. These are introduced between the plates 33 and 34 by a conveying means 39 provided with a slide 39a and a broad-threaded screw 39b driving said box bodies.
  • the bottoms or covers 12 are also introduced between the plates 33 and 34, by another suitable conveying means 42, here in the form of a conveyor belt.
  • the end parts of the conveying parts 39 and 42 are arranged substantially tangentially to the drum 14, between the plates 33 and 34.
  • An auxiliary evacuation cylinder 45 provided with semi-cylindrical lateral recesses 46 is mounted rotating in the vicinity of the periphery of the cylindrical part 36. It is rotated in synchronism with the drum 14 and cooperates with a guide 48 to deposit the body of boxes provided with their bottoms or covers on a conveying means 49 conveying them to a clamping station shown in FIG. 7.
  • the latter is conventional and essentially comprises two knobs 52, 54 between which the internal rolled fastening the box body 13 and the bottom or cover 12, is capable of being crushed radially to ensure perfect sealing of the assembly.
  • the bottoms or covers 12 which are routed to the dies 18 are preformed to each have an inwardly rolled edge 12a.
  • This rolled edge can conventionally be obtained by stamping, using a tool of suitable shape, which it has not been deemed useful to represent, this operation being in itself trivial.
  • the funds or covers 12 thus preformed are deposited on the conveying means 42 so that said rolled edges 12a are oriented towards the plate 33 when the bottom or cover reaches the end of said conveying means.
  • the movement of the latter is synchronized with the rotation of the drum 14 so that a bottom or cover 12 reaches below a die 18, in the situation illustrated in FIG. 2.
  • the pusher 22 then lowers until 'that the gripping means 29 comes into contact with the central part of the bottom or cover 12.
  • the invention is applicable to the assembly of a deformable bottom or cover which is not necessarily metallic on a metal box body.
