Definitions

  • Tins or cans are made starting with a sheet of plate or metal material which is bent and welded, longitudinally, to form an empty tubular body whose ends are closed, during a step which follows the beading step, by corresponding circular portions or ends, also made of metal material, which are usually applied by welding.
  • the tin is an empty tubular body with open ends.
  • Beading is formed by machines usually equipped with a head or carousel able to rotate, respectively, between a station for feeding the tins on which beading must be formed and a station for unloading the tins on which beading has been formed.
  • the contact between the mandrel and the surface of the circular sector guarantees that the tin is locked along the direction perpendicular to the tin direction of feed.
  • the lower part of the tin rests on a ring-shaped fixed supporting surface which is part of a tin gripping and positioning unit.
  • the plate remains in contact with the upper end edges of the tin for the entire period during which the tin is along the path defined by the circular sector.
  • the gripping unit is raised so that the tin can be released from the mandrel. Then, the upper contact plate, rotating about the pivoting axis, allows the tin to be definitively released to a subsequent station.
  • the screw - spring pair which should guarantee the contact plate grip is not very precise and is difficult to adjust, said adjustment varying according to the dimensions of the tin on which beading must be formed.
  • Tin axial upward movement results in the formation of helical beading (even if the angle is limited), not uniform relative to the outer cylindrical surface of the tin.
  • a second disadvantage is the fact that the contact plate, which remains stationary relative to the tin during tin rotation, tends to rub the end edges of the tin, with the possibility of removing material or paint, substantially compromising the integrity of the tin.
  • the numeral 1 denotes a generic tin made of metal material or the like.
  • the tin 1 has an upper opening 2, delimited by an end edge 3, and a lower opening 4.
  • tin 1 beading is carried out in a beading machine which may comprise a head or carousel 5 able to rotate about a predetermined axis of rotation A (see arrow F5).
  • the carousel 5 moves and supports the tins 1 on which beading must be formed.
  • the tin 1 is able to rotate relative to the supporting surface 6 about its own axis of rotation B'.
  • the supporting surface 6 may rotate idly and rotates together with the tin 1.
  • each supporting surface 6 there is a relative tin 1 guiding and retaining mandrel 7, also integral with the carousel 5 and able to rotate thanks to gears (not illustrated) about an axis M.
  • the mandrel 7 may rotate idly about its own axis M.
  • the supporting ring 6 movement is driven by known means which are therefore not described in detail.
  • the mandrel 7 is shaped to match the beading sector 8 so that, when the mandrel 7 engages the tin 1, the tin 1 body is inserted between the outer surface of the mandrel 7 and the inner surface 101 of the beading sector 8.
  • Each contact plate 10 is opposite the supporting ring 6 with which it is associated, forming a tin 1 containment zone.
  • the contact plate 10 has a section with the shape of an inverted "U", where the concave part of the U faces the tin 1 and the ends of the plate 10 rest on the edge 3 of the tin 1.
  • the contact plate 10 may have a projecting portion 100 designed to completely fit the tin 1 upper opening 2, as illustrated in Figures 2, 3 and 4.
  • the contact plate 10 may consist of a sector formed by two or more crossed rod-shaped elements, having a plurality of contact points with the edge 3 of the tin 1, said points being symmetrically and uniformly distributed on the edge 3.
  • the contact plate 10 is supported by a plate 11 slidably mounted on a rod-shaped element 12 and is able to move vertically along a direction D, between a raised position in which it is distanced from the tin 1, and a lowered position in which it is in contact with the tin 1.
  • FIG. 1 shows a portion 102 of a cam profile (associated with the carousel 5) engaged by a cam follower 103 associated with the supporting plate 11.
  • the rod-shaped element 12 comprises a bracket 13.
  • the first end 14 of the bracket 13 is rigidly connected to the rod-shaped element 12 by a screw 15, and the second end 16 of the bracket is connected to the contact plate 10 supporting plate 11 by a screw 17 and helical spring 18 connection.
  • a tin 1 on which beading must be formed is fed from a tin 1 feed station, as illustrated in Figure 1.
  • the contact plate 10 is raised to allow tin 1 positioning on the ring 6.
  • the spring 18 connected to the bracket 13 is compressed.
  • the contact plate 10 is lowered thanks to the movement transmitted by the cam mechanisms 102 - 103 to the supporting plate 11, to which it is connected.
  • the contact plate 10 In its lowering stroke, the contact plate 10 does not return to its original position, but remains slightly raised, due to the presence of the tin 1.
  • Said force is transmitted to the tin 1, which in this way is subject to extra axial locking, in addition to the normal force applied by the contact plate 10 deriving from the position imposed on it by the cam mechanism.
  • the contact plate 10 rests on the whole of the edge 3 of the tin 1, consequently applying a uniform pressure on the tin 1 and so preventing even small amounts of axial sliding which would compromise the success of the beading operation.
  • the mandrel 7 is inserted in the tin 1.
  • the tin 1 runs along the circular sector 8, forced against it by the action of the mandrel 7.
  • the tin 1 cylindrical body is inserted between the inner surface 101 of the beading sector 8, having the projections 9, and the outer surface of the mandrel 7, shaped to match the inner surface 101 of the beading sector 8.
  • the beading is formed on the tin 1, which rolls without slipping along the beading sector 8 about its own axis of rotation B'.
  • the invention brings important advantages.
  • the shape of the contact plate that is to say, the fact that its surface is made in such a way that its points of contact with the tin are at least uniformly distributed on the whole of the edge of the tin, allows a force distributed on the whole of the edge to be applied and very effective balancing of the axial thrust generated on the tin during its passage in the beading sector.
  • connection between the contact plate and the carousel structure allowing the contact plate to rotate freely about its axis, allows the contact plate to rotate together with the tin, thus avoiding any kind of rubbing or removal of material and/or paint.
