Definitions

  • the present invention relates to a machine for closing drums with a lid and a lever-operated closing ring or the like.
  • Drums which have a substantially cylindrical body open at its top flat surface and have, at this open flat surface, a flanged edge on which the edge of a lid rests, with the possible interposition of a sealing gasket.
  • These drums are generally closed by using a lever-operated ring having a circular body with a substantially C-shaped radial cross-section, so as to engage below the flanged edge of the drum and above the edge of the lid.
  • These closing rings have a discontinuity along their circumferential extension, and at this discontinuity the two portions of the ring are mutually superimposed and can slide inside one another.
  • a lever is also pivoted to one of these portions at this discontinuity, said lever being connected to the other portion by means of a link or of a pair of links, one end of which is pivoted to an intermediate portion of the lever while the opposite end is pivoted to the other portion of the ring.
  • the lever In open position, the lever is orientated along a direction substantially radial with respect to the ring, and its oscillation toward the ring portion to which it is pivoted is allowed only in one direction, due to the link or pair of links connecting it to the other portion, and causes the circumferential sliding of this portion along the other portion and consequently a reduction in the total diameter of the ring which closes the ring around the upper edge of the drum, rigidly coupling the lid thereto.
  • Drums which use a lever-operated closing ring are currently closed manually in onerous working conditions for the operators, who must keep the pace of modern filling lines in order to avoid excessively penalizing the productivity of these facilities.
  • the aim of the present invention is to solve the problems described above by providing a machine which can automatically close drums with a lid and a lever-operated closing ring, or the like.
  • Another object of the present invention is to provide a machine which can close drums at a working rate which allows to fully exploit the productivity of modern filling machines.
  • Another object of the invention is to provide a machine highly reliable in operation.
  • a further object of the invention is to provide a machine which can close drums having different capacities and heights.
  • a machine for closing drums with a lid and a lever-operated closing ring or the like comprising: means for moving the drums along an advancement direction; means for supporting a closing ring in an open position around a lid which rests on the upper edge of one of the drums; a closing station comprising means for stopping one of the two drums in said closing station; means for locking said closing ring; closing means which can engage, when actuated, the lever of said closing ring to move it from the open position to said closed position, in which said closing ring engages around said lid and around the upper edge of said drum.
  • the machine generally designated by the reference numeral 1, comprises a supporting structure 2 which supports means for moving a drum 3 along an advancement direction 4 and means 5 for supporting a closing ring 6 in open position around a lid 7 which rests on the upper edge of one of the drums 3.
  • the movement means are constituted by a conveyor belt 8 which winds around rollers 9 having horizontal and mutually parallel axes and supported by the supporting structure 2. At least one of the rollers 9 is actuated so that it rotates about its own axis by virtue of known actuation means, to cause the advancement of the upper portion of the conveyor belt 8, on which the drums 3 rest, along the advancement direction 4.
  • the means for supporting the closing ring 6 are substantially constituted by a pair of guides 10a and 10b supported by the supporting structure 2, parallel to the advancement direction 4 and mutually spaced so that the drums 3 can advance between them.
  • the guides 10a and 10b are arranged at a vertical level which substantially matches the level of the upper edge of the drums 3 arranged on the conveyor belt 8, so that the ring 6 arranged on said guides is correctly positioned vertically with respect to the related drum 3 and to the lid 7 which closes the drum at the top.
  • the guides 10a and 10b extend for a certain length along the conveyor belt 8, upstream of and at a closing station, designated by the reference numeral 11, located along the conveyor belt 8.
  • Said stop means comprise two abutments 13a and 13b arranged mutually opposite along a direction which is transverse to the advancement direction 4 and can move, when actuated, along said transverse direction to engage two lateral regions of the drum 3, arranged in each instance at the closing station 11 by advancement along the direction 4, and disengage therefrom in a cyclic manner.
  • Said abutments 13a and 13b are supported by a frame 14 and are actuated by means of a pair of fluid-driven actuators 15a and 15b, such as for example known pneumatic cylinders.
  • closing means which can engage, when actuated, the lever 6a of the closing ring 6 to move it from the open position to the closed position, in which said closing ring 6 engages around the lid 7 and around the upper edge of the drum 3.
  • Said closing means comprise a presser element 16 which is substantially disk-like and is supported by vertical posts 17 slideable within bushes 18 which are rigidly coupled to the frame 14 to allow the presser element 16 to pass from an inactive position, in which it is spaced upward from the lid 7 which rests on the upper edge of the drum 3 in the closing station 11, to an active position in which it acts, with a preset pressure, on the lid 7 in the direction of the underlying drum 3.
  • a fluid-driven actuator 19 for example a pneumatic cylinder, arranged so that its axis is vertical, i.e. parallel to the extension of the guides 17, and acts on the presser element 16 with the stem of its piston.
  • the closing means located at the closing station 11, also comprise an arm 20 which is pivoted, with one of its ends, to the upper face of the presser element 16 and extends, with its other end, beyond the space occupied by the presser element 16, coaxial to the drum 3 when said drum 3 is located in the closing station 11.
  • the arm 20 is pivoted to the presser element 16 about an axis 21 which is parallel and spaced with respect to the axis 16a of the presser element, which as mentioned substantially coincides with the axis of the drum 3 located in the closing station 11; said pivoting axis 21 is arranged in a lateral region of the presser element with respect to the advancement direction 4.
  • the stem 22a of a fluid-driven actuator 22, for example a pneumatic cylinder, is hinged to the other end of the arm 20 and is supported by the presser element 16 by means of an L-shaped bracket 23.
  • the fluid-driven cylinder 22 is orientated so that its axis is parallel to the advancement direction 4, so that the actuation of said fluid-driven cylinder causes the oscillation of the arm 20 about the axis 21.
  • the arm 20 On its lower face, the arm 20 has a pivot 24 which extends toward the underlying conveyor belt 8 and can engage the lever 6a of the ring 6 to move said lever from the open position to the closed position, as will become apparent here
  • the pair of presser elements 25a and 25b faces two opposite lateral regions of the half-ring directed toward the advancement direction 4.
  • the pair of presser elements can be moved, when actuated, along directions which are radial with respect to the closing ring 6, so as to apply on said ring two forces orientated toward the axis of the closing ring 6 and with mutually opposite components, so as to lock the rotation of the closing ring 6 and the movement thereof along its plane of arrangement.
  • the pair of presser elements 25a and 25b is actuated by means of fluid-driven actuators, for example pneumatic cylinders 26a and 26b mounted on the frame 14.
  • Said positioning means comprise a rod 27 orientated transversely to the advancement direction 4 and facing the region of the presser element 16 to which the arm 20 is pivoted.
  • the rod 27 is slideably supported along its axis by the frame 14 and can move, when actuated, along its longitudinal axis from an inactive position, in which it does not interfere with the lever 6a of the ring 6, to an active position in which it retains the lever 6a of the closing ring 6 at the arm 20 of the closing means.
  • Movement of the lever 27 from the inactive position to the active position and vice versa is obtained by virtue of a fluid-driven actuator, for example a pneumatic cylinder 28, which is supported by the frame 14 and acts with the stem 28a of its piston on the rod 27 by means of an oscillating lever 29.
  • a fluid-driven actuator for example a pneumatic cylinder 28, which is supported by the frame 14 and acts with the stem 28a of its piston on the rod 27 by means of an oscillating lever 29.
  • the closing means, the means for supporting the closing ring and the means for locking the closing ring are associated with a bridge-like frame 14 slideably mounted on a pair of vertical guides 30a and 30b arranged laterally on opposite sides with respect to the conveyor belt 8.
  • the frame 14 can move, when actuated, along the vertical guides 30a and 30b in a per se known manner, for example by means of a pair of gears 31a and 31b supported by the guides 30a and 30b, actuatable by means of an actuation handwheel 32, and meshing with racks 33a and 33b which are rigidly coupled to the uprights of the frame 14 so as to adapt the position of the various elements arranged in the closing station 11 to the height of the drums 3.
  • the drum 3 advances along the direction 4, moving the closing ring 6 which, by virtue of this advancement, engages against the lever 27 with its lever 6a.
  • the combined action of the lever 27 and of the advancement of the closing ring 6 causes the correct placement of the closing ring 6 around the axis of the drum.
  • the abutments 13a and 13b are actuated, stopping the drum in the correct position with respect to the overlying presser element 16.
  • the pneumatic cylinder 19 is actuated, lowering the presser element 16 onto the lid 7 and applying on said lid a pressure calibrated so that the compound or sealing element interposed between the lid and the drum assumes the correct shape.
  • the pair of presser elements 25a and 25b is actuated and, by pressing on the half of the closing ring 6 which faces the advancement direction 4, prevents the closing ring 6 from rotating about its own axis or from moving in the horizontal plane where it is arranged.
  • the rod 27 is disengaged from the closing lever 6a and the pneumatic cylinder 22 is actuated, causing the oscillation of the arm 20 about the axis 21. Due to this oscillation, the pivot 24 engages against the outer side of the lever 6a and follows a curved path which progressively approaches the perimeter of the closing ring 6, closing the lever 6a against the ring 6. Closure of the lever 6a reduces the total diameter of the closing ring 6 and thus closes the ring 6 around the upper edge of the drum 3 and around the lid 7.
  • the arm 20 is then returned to its initial position, and the presser element 16 is raised above the closed drum, whereas the pair of abutments 13a and 13b is disengaged from the drum and the pair 25a and 25b is disengaged from the ring 6, which is by then closed, so that the drum 3 can continue its advancement toward a downstream packaging station.
  • the materials employed, as well as the dimensions, may be any according to the requirements and the state of the art.
