Definitions

  • the present insertion relates to the manufacture of barrels for the storage and transport of products, for example pulverulent.
  • a more particular subject of the invention is a method for manufacturing drums, the document DE-A-1461580 of which reveals the characteristics mentioned in the preamble of claim 1, a device for manufacturing drums, of which document US-A-4183315 reveals the characteristics mentioned in the preamble of claim 2, and the drums thus produced.
  • This type of barrel generally comprises a cylindrical tubular body made from wood fibers, and for example from cardboard.
  • each flange On each end of the body is introduced respectively a lower and upper flange each extending over a part of the peripheral surface of said body.
  • Each flange is deformed so as to form a groove extending towards the inside of the body which, consequently, has on its internal face an annular rib.
  • a bottom disc is fixed against the lower rib of the body by crimping the lower flange while simultaneously rolling the peripheral edge of said flange and said body.
  • the peripheral edge of the upper flange is identically rolled towards the inside of the tubular body so as to define the opening of the barrel.
  • the barrel thus produced is closed by a disc-shaped cover, the peripheral part of which has the shape of a skirt extending downwards so as to cover the upper part of the upper flange.
  • the cover is retained in place using a tightening band or collar fixed around said skirt by an appropriate tightening mechanism.
  • the device comprises a series of internal jaws distributed over a circle and movable in a direction perpendicular to the axis of the body of the barrel, from the center to the periphery, and a series of external jaws distributed over a concentric circle and of larger diameter than the circle formed by said internal jaws and movable in a direction perpendicular to the axis of the barrel body, from the periphery to the center.
  • the internal jaws are provided, on their external face, with a groove and the external jaws are provided on their internal face with a rib situated opposite and of complementary shape to said groove, with the internal jaws to form a groove on the upper flange extending inward of said body.
  • the device also comprises a crown arranged in the space provided between the internal and external jaws.
  • This crown movable in a direction parallel to the axis of the barrel body, is provided on its upper face with a groove intended to receive the peripheral edge of the upper flange.
  • the displacement of the crown makes it possible to roll inward the peripheral edge of the upper flange.
  • the barrel is turned over and transferred to another device.
  • the upper part of the upper flange defining the opening of the barrel has an external diameter equal to or greater than the external diameter of the barrel.
  • US-A-4,183,315 is a device for fixing a cover to the body of a box.
  • This device comprises a series of internal and fixed jaws comprising on their underside a rib of shape complementary to a groove formed on the cover and a series of external jaws movable in a direction perpendicular to the axis of the body of the box and comprising on their internal face a groove intended to receive the peripheral edge of the cover. Moving the outer jaws towards the inner jaws allows the cover to be crimped onto the body of the box.
  • the upper part of the collar defining the opening of the box has an external diameter greater than the diameter of the body of the box.
  • the present invention therefore aims to avoid these drawbacks by proposing a method and a device for manufacturing drums to reduce the radial size of these drums.
  • the subject of the invention is a method of manufacturing a barrel comprising a cylindrical tubular body, as described in claim 1, in which simultaneously with the formation of the groove on the upper flange and the corresponding annular rib on the face internal of the body, a portion of said upper flange is shrunk between the annular rib and the opening of the barrel, and, during this shrinkage, the peripheral edge of said upper flange and said body is supported and guided so that the diameter of said part between the annular rib and the opening of the barrel is less than that of the lower part of said upper flange between the two annular ribs and that the tightening band of the cover, after its installation, is aligned with the part between the two annular ribs of said upper flange.
  • the invention also relates to a device for manufacturing a barrel comprising a cylindrical tubular body provided at each of its ends respectively with a lower and upper flange extending over a part of the peripheral surface of said body, as described in claim 2, which comprises means for constricting the part between the annular rib and the opening of the barrel and means for supporting and guiding the peripheral edge of said flange and the body of the barrel in a plane perpendicular to the longitudinal axis of the said barrel body.
  • the invention also relates to a storage and transport barrel produced by the process mentioned above.
  • a barrel 1 consisting of a cylindrical tubular body 2 made from wood fibers and for example from cardboard.
  • a lower flange 3 and an upper flange 4 are introduced on the ends of the body 2, each flange extending over part of the peripheral surface of said body 2.
  • a groove 3a extending towards the inside of the body 2 is formed on the lower flange 3 so as to produce on its internal face an annular rib 2a ensuring the crimping of said lower flange 3 on said body 2.
  • a disc 5 forming a bottom is placed on the annular rib 2a, and the edge of the lower flange 3 and of the body 2 are rolled simultaneously so as to crimp the disc 5.
  • the barrel is turned over and a groove 4a extending towards the inside of the body 2 is formed on the upper flange 4 so as to produce on its internal face an annular rib 2b ensuring the crimping of said upper flange 4 on said body 2, and the peripheral edge of this upper flange 4 and of this body 2 is rolled inwards simultaneously so as to form the opening of the barrel.
  • the barrel is closed by a disc-shaped cover 6, the peripheral part of which has the shape of a skirt extending over the bottom so as to cover the upper part 4b of the upper collar 4.
  • the cover 6 is retained in place using a clamping band 7 fixed around the skirt of the cover 6 by an appropriate clamping mechanism, not shown.
  • the upper part of said flange 4 is constricted so that the diameter of said part upper 4b is less than that of the lower part 4c of said flange 4 and that the tightening strip 7 of the cover 6, after its installation, is substantially aligned with the body 2 of the barrel.
  • the device according to the invention comprises a series of internal jaws 10 of complementary shape to each other so as to define in a closed position a circle 11.
  • the internal jaws 10 are slidably mounted on a support 12 and are movable, under the action of suitable means, not shown, in a direction perpendicular to the axis of the body of the barrel and from the center towards the periphery.
  • the device also includes a series of external jaws 14 of complementary shape each to the others so as to define in the closed position, a concentric circle 15 of larger diameter than the circle 11 formed by the internal jaws 10.
  • Each external jaw 14 is pivotally mounted on a horizontal axis 16 which is itself mounted on a support 17 (Fig. 3).
  • each jaw 14 is movable, under the action of suitable means, not shown, in a direction perpendicular to the axis of the body of the barrel and from the periphery towards the center.
  • the internal face of these external jaws 14 includes a rib 18 located opposite and of complementary shape to the groove 13 of the internal jaws 10.
  • the part 14a situated below the rib 18 of the external jaws 14 is situated in front, by a distance "a" (Fig. 4), relative to the part 14b situated above said rib of so as to achieve the constriction of the upper part 4b of the upper flange 4 of the barrel, as will be seen later.
  • the internal 10 and external jaws 14 provide a space below which a crown 20 is positioned, provided on its upper face with a groove 21.
  • This crown 20 is movable, by suitable means not shown, in a direction parallel to the axis of the body of the barrel.
  • the device also comprises means for supporting and horizontal guiding of the peripheral edge of the upper flange 4 and of the body 2 of the barrel which consist of plates 22, for example four in number, uniformly distributed around the crown 20.
  • the upper face of each pad 22 is located at the level of the groove 21 of said crown 20.
  • each stud 22 can optionally be provided with a wear plate 23.
  • the means for supporting and horizontal guiding of the peripheral edge of the upper flange 4 and of the body 2 of the barrel can be constituted by a ring-shaped part placed around the crown 20 and the face of which upper is also located at the groove 21 of said crown.
  • the internal 10 and external jaws 14 are in the open position and the body 2 of the barrel provided with the upper flange 4 falls between said jaws in such a way that the peripheral edge of said callerette and of said body is in contact with the upper face of the dishes 22 as shown in FIG. 4.
  • the part 14a of the external jaws 14 realizes the constriction of the upper part 4b of the flange 4 relative to the lower part 4c of said flange, so that the peripheral edge of this flange and of the body 2 slides on the dishes 22 and enters the groove 21 of the crown 20 (Fig. 5).
  • the crown 20 moves vertically which has the effect of rolling towards the inside of the barrel, simultaneously the peripheral edge of the upper flange 4 and of the body 2 so as to form the opening of the barrel.
  • the part 14a of the external edges 14 ensures the maintenance of the upper part 4b of the upper flange 4.
  • the external jaws open and the barrel can be removed.
  • the tightening band of the cover is after its installation more or less aligned with the lower part of this flange and in this way obtains a drum having roughly constant overall dimensions, which makes it possible to reduce the radial size without reducing the capacity of these drums.
