Definitions

  • the present invention relates to a device for crimping the lid of cans, comprising a crimping head and a compression foot intended to support the body of a can on which a lid has been placed and pressing the latter on the box body, by pushing the box against a fixed mandrel with a determined force, during the entire crimping operation;
  • the compression foot is fixed to the end of a first element of a telescopic rod which extends along an axis perpendicular to the load-bearing surface offered by the compression foot and comprises two elements which can slide one relative to the other, with which is associated a spring which tends to separate them from each other, while the second element is coupled to a motor means capable of imposing on it an alternating movement of longitudinal translation between two defined extreme positions, namely a rest position, remote from the aforementioned mandrel, and a working position causing the compression of the cover on the box body by the mandrel via said spring, the first element of the rod and the compression foot.
  • the role of the compression foot is to press the cover on the box body with more or less force during the crimping phase, during which the edge of the cover is rolled around the edge of the box body, then crushed in order to '' obtain a sealed connection by peripheral crimping.
  • the pressure exerted on the cover has a decisive influence on the quality of the crimping roll produced along the edge of the cover. It must have a well-defined constant value for a given type of box; too low or too high a pressure leads to faulty crimping.
  • the compression foot is supported on the aforementioned second element, serving as a control member, by means of the spring, the assembly performing an alternating movement all the more rapid as the rate of crimping is high.
  • the spring is biased at each stroke of the assembly in the direction of the crimping box, due to the inertia of the compression foot and the first element to which it is fixed; as it only correctly exerts the pressure required for crimping when it is stabilized, it can be seen that the degree of compression differs from the desired value, all the more so as the rate increases, especially if the crimp boxes are of a type requiring a small compressive force, therefore a relatively weak spring (this is the case for example of thin-walled light alloy boxes).
  • the object of the present invention is to overcome this incompatibility.
  • the stroke of the support rod of the compression foot is subdivided into two parts: a first part where the two elements of the rod, locked together, behave like a single piece, so that the compression foot performs faithfully the movement imposed by the motor means, whatever the amplitude of the acceleration impressed by it, and this without the spring being in any way stressed. Then, in a second part, which corresponds to the end of travel of the compression foot, the first element dissociates from the second, on which it only depends by through the spring. This then plays its role by exerting the desired compression force on the cover to be crimped.
  • the locking means of the two elements of the telescopic rod comprise a chamber delimited by walls belonging respectively to one and to the other of these elements, the internal volume of which is directly determined by the position mutual of these when they slide relative to each other, and a stop means which determines the situation of maximum extension of the rod;
  • the chamber is permanently connected to a source of pressurized liquid and, but only when the rod will reach its end-of-travel position in the direction of the mandrel, to a path for discharging this liquid out of the chamber.
  • the liquid filling the chamber forms an incompressible hydraulic cushion trapped between the two elements, which it rigorously secures, the two elements being suddenly released from this connection as soon as the liquid can escape from the chamber.
  • This can be connected to the source of pressurized liquid by a pipe comprising a non-return valve, which prevents, during the compression phase, any return of the hydraulic liquid to the source and ensures perfect containment of it in the chamber even if the source delivers it under a not very high pressure.
  • the device is designed so that the internal volume of the chamber increases or decreases depending on whether the elements of the rod slide mutually to extend the latter or make it retract, respectively.
  • the chamber should be delimited by a bottom and a tubular side wall belonging to one of the two elements of the rod and by a piston constituted by the end of the other element, this piston sliding at the interior of the chamber, and that said side wall is pierced with a first orifice communicating permanently with the source of pressurized liquid, and a second orifice communicating with a discharge conduit only at the end of the travel of the element to which said side wall belongs.
  • the element to which the side wall of the chamber belongs is the first element, the piston being constituted by the end of the second element.
  • abutment means may comprise a key transversely passing through both the first and the second element of the rod, one of them at least by a buttonhole or a pair of buttonholes allowing between the two elements a play sliding amplitude greater than the residual stroke performed by the second element after its unlocking with the first, in order to avoid any risk of mechanical short-circuit of the spring at the end of the stroke by means of the key.
  • the ends of the latter should also be received in a pair of guide slots hollowed out in a fixed part and extending along the direction of the axis of the telescopic rod, in order to stabilize the telescopic rod around its axis. , without the possibility of rotation, and thus force the compression foot to maintain a constant orientation relative to the fixed mandrel.
  • Figures 1 and 2 schematically show, in axial section, a device according to the invention, respectively at the time of arrival in the crimping head of a can to be crimped, and during the crimping operation.
  • a can 1 consisting of a box body 1a and a cover 1b which covers it. These two elements are already provisionally linked to each other by two "clinching" points where the edge of the cover 1b has been locally crimped to the upper edge of the box body 1a.
  • the can 1 in this situation was previously brought, by sliding on a support plane P under the action of a transport star (not shown), to rest on a plate 2 called “compression foot", just at below a fixed mandrel 3, in the centered position, like the compression foot 2 and the mandrel 3, on the axis 4 of a crimping head.
  • This includes rotary crimping wheels, only one of which is shown, designated by the reference 5.
  • the compression foot 2 is mounted at the top of a telescopic rod 7, aligned on the axis 4 of the crimping head.
  • This rod consists of a first upper element 7a and a second lower element 7b, capable of sliding mutually in the direction of the axis 4.
  • the element 7a is hollowed out so as to form a chamber internal cylindrical 8 delimited by a first bottom 8a and a side wall 8c belonging to this element, as well as by a second bottom 8b formed by the end of the element 7b which slides in the chamber 8 like a piston.
  • the amplitude of this sliding is limited by a key 9 pinning transversely through the element 7b, to which it is secured, and through the wall of the chamber 8 (or more exactly its extension) via a pair of buttonholes 10 in which the key 9 can play somewhat in the direction of the axis 4.
  • the ends of the key 9 are guided in slots 11 extending in the direction of the axis 4, which are hollowed out radially in a jacket 12 fixed surrounding the upper element 7a, which can slide longitudinally there.
  • the cooperation of the key 9 with the slots 11 prevents any rotation about the axis 4 of the elements 7a, 7b of the rod 7, therefore of the compression foot 2 linked to the element 7a.
  • a compression spring 13 which is held there under a certain preload of adjustable value using means not shown. This spring tends to cause the two elements 7a, 7b to move away from one another.
  • the telescopic rod 7 is driven in an alternating movement in the direction of the axis 4 in order to raise the compression foot 2 towards the mandrel 3 or to move it apart by lowering at the desired times of the successive cycles of the crimping operations.
  • the element 7a is fixed in lateral projection, in its lower part, a part 14 supporting a rotary roller 15 of axis 16 perpendicular to the axis 4.
  • This roller is engaged in a guide track 17 closed on itself, of suitable layout, which comprises a plate 18 rotating around its axis 19, parallel to the axis 16 of the roller 15, under the action of a motor (not shown).
  • the fixed jacket 12 is pierced with two radial conduits 20, 21; one, designated by the reference 20, is connected, via a non-return valve 22, to a source 23 of pressurized liquid (in the present example, it is the source of lubricating oil by bubbling the mechanism 14-18 for driving the element 7b); the other, designated by the reference 21, opens into the outside atmosphere.
  • the side wall 8c of the chamber 8 is pierced with two orifices 24, 25.
  • the orifice 24 has an elongated shape in the direction of the axis 4 so that, during the translational movements of the element 7a, the conduit 20 of the jacket 12 remains constantly facing the orifice 24, and that as a result the chamber 8 can permanently receive liquid from the source 23.
  • the orifice 25, of reduced section similar to that of the conduit 21, is positioned so as to come opposite it only when the element 7a will reach the end of its stroke towards the mandrel 3.
  • the compression force of the cover 1b on the box body 1a which results therefrom can be relatively low, because it only intervenes at the end of the travel of the element 7a, which is actuated during most of its travel. independently of the spring 13, being locked hydraulically with the element 7b moved by the roller 15 via the chamber 8 filled with oil and closed.
  • This mode of actuation in translation of the compression foot 2 therefore allows both a high rate of operation without annoying inertia effect of the element 7a relative to the element 7b, and a measured intensity of the compressive force applied to the cover 1b on the box body 1a; this intensity can in particular be adjusted to a very low level when the box body is fragile, being produced for example from very thin aluminum sheet.
  • the roller 15 in its guide track 17 then maintains, via the rod 7 and the compression foot 2, the cover 1b pressed on the box body 1a during the whole time that the crimping wheels, having moved closer in contact with the box 1, revolve around the latter, realizing on its entire periphery the fixing of its cover by crimping.
  • the elements 7a, 7b are connected only by the spring 13, which implies that the buttonholes 10 in which the key 9 is engaged are long enough for the latter, having left their lower end when the spring 13 compresses, does not come to abut against their upper end, which would unduly restore a rigid connection between the two elements 7a, 7b.
  • the roller 15 begins to lower the element 7b.
  • the element 7a does the same, driven by the key 9 which comes into contact with the lower end of the buttonholes 10.
  • the orifice 25 of the chamber 8 leaves the discharge conduit 21, so that the oil contained in the chamber there is again held captive and that, as a result, the hydraulic locking is restored between the elements 7a and 7b of the rod 7, which finally resumes, under the action of the roller 15, its low position illustrated in the figure 1.
  • the implementation of the device described for the crimping of cans makes it possible to increase the rate from 80 cans / min approximately to 200 cans / min or more, the rate then being limited by the crimping head rather than by the compression mechanism.
