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 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 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.

- 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 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.

- 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 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.

Abstract
Description
- The present invention relates to a beading machine, in particular relative to the production of container bodies.
- This description refers to tubular container bodies such as tins or cans, without in any way limiting the scope of the invention.
- As is known, the production of spaced beading on the lateral walls of tins or cans prevents the formation of bulges or the collapse of the tins or cans, especially if they are large.
- 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.
- Therefore, the beading is formed on the lateral surface of the tin before the tin is filled with product and closed.
- Thus, during the beading step, 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.
- In this description reference is made to beading machines in which the tins on which beading must be formed are gravity fed, that is to say in which the feed station is raised relative to the beading zone. This allows the tin to be inserted in a mandrel which accompanies the tin along a beading path, forcing it into contact with a circular sector adjacent to the carousel, having a predetermined angle of curvature and having, on the surface which makes contact with the tin, projections which are parallel with one another and designed to form the beading.
- The mandrel keeps the outer surface of the tin in forced contact with the surface of the circular sector having the projections and is shaped to match the latter (that is to say, having circular grooves parallel with one another), allowing the beading to be formed.
- The mandrel rotates relative to the tin and, in turn, the tin rolls without slipping along the circular sector.
- 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. During its movement in the beading station, the lower part of the tin rests on a ring-shaped fixed supporting surface which is part of a tin gripping and positioning unit.
- Tin sliding along its axis of rotation (vertically) is prevented by a contact plate, which is part of said unit, partly resting on the edge of the tin.
- The contact plate is hinged, on one side, so that it is able to rotate about an axis perpendicular to the tin axis of rotation and it is driven by cam mechanisms.
- 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 force needed to keep the contact plate in contact with the edges of the tin is applied by a screw and a helical spring, located above the contact plate.
- As soon as the tin leaves the circular sector contact zone, that is to say, when the beading has been formed, 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.
- Basically, the following are present:
- an arrival station
- a fixed circular beading sector
- a rotary carousel located inside the sector and having a plurality of idle mandrels
- a plurality of gripping elements comprising a lower supporting surface and a movable upper contact plate.
- Prior art beading machines have several disadvantages.
- During the beading step, particularly if a large amount of close beading must be formed, the forces generated by the circular beading sector projections often tend to move the tin along its axis of rotation, upwards.
- This pushing action must be counteracted by the contact plate, but the contact plate does not apply a uniform pressure on the whole of the tin, which can therefore move along its longitudinal axis or rise up in the zone in which the contact plate applies less force.
- 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 aim of the present invention is therefore to overcome the above-mentioned disadvantages by producing a beading machine which is effective, economical and easy to adjust.
- The technical features of the present invention, in accordance with the above aim, are clear from the content of the claims herein, in
particular claim 1 and, preferably, from any of the claims directly or indirectly dependent onclaim 1. - The advantages of the present invention are more evident in the detailed description which follows, with reference to the accompanying drawings which illustrate a preferred, non-limiting embodiment of the invention, in which:
- Figure 1 is a schematic view with some parts in cross-section of a detail of the machine made in accordance with the present invention, in a first operating configuration;
- Figure 2 is a schematic view with some parts in cross-section of a detail of a beading machine made in accordance with the present invention, in a second operating configuration;
- Figure 3 illustrates an enlarged detail from Figure 2;
- Figure 4 illustrates another embodiment of the detail from Figure 3;
- Figure 5 illustrates another embodiment of a detail of the machine in accordance with the present invention;
- Figure 6 is a schematic perspective side elevation view of a tin made in the machine in accordance with the present invention;
- Figure 7 is a schematic plan view, with some parts cut away, of a machine in accordance with the present invention.
- With reference to the accompanying drawings and in particular with reference to Figure 6, the
numeral 1 denotes a generic tin made of metal material or the like. - The
tin 1 has anupper opening 2, delimited by anend edge 3, and alower opening 4. - As shown in Figure 7,
tin 1 beading is carried out in a beading machine which may comprise a head orcarousel 5 able to rotate about a predetermined axis of rotation A (see arrow F5). Thecarousel 5 moves and supports thetins 1 on which beading must be formed. - Connected to the
carousel 5 there is a plurality of ring-shaped supportingsurfaces 6, that is to say, supportingrings 6, on which thetins 1 on which beading must be formed are placed. - According to a first embodiment, the
tin 1 is able to rotate relative to the supportingsurface 6 about its own axis of rotation B'. - Alternatively, according to another embodiment, the supporting
surface 6 may rotate idly and rotates together with thetin 1. - Associated with each supporting
surface 6 there is arelative tin 1 guiding and retainingmandrel 7, also integral with thecarousel 5 and able to rotate thanks to gears (not illustrated) about an axis M. - According to another embodiment, not illustrated, the
mandrel 7 may rotate idly about its own axis M. - As Figures 1 and 2 show, the supporting
ring 6 moves along its axis B between a raisedtin 1 loading position, in which themandrel 7 is below the supportingring 6, and a lowered operating position, in which themandrel 7 is inside the supportingring 6 and engages thetin 1 positioned on the supportingring 6. - The supporting
ring 6 movement is driven by known means which are therefore not described in detail. - As illustrated in Figures 2, 3, 5 and 7, outside the beading machine and adjacent to it, there is a
circular beading sector 8 having aninner surface 101 on which there is a plurality ofprojections 9 designed to form the beading. - The
mandrel 7 is shaped to match thebeading sector 8 so that, when themandrel 7 engages thetin 1, thetin 1 body is inserted between the outer surface of themandrel 7 and theinner surface 101 of thebeading sector 8. - Also associated with each supporting
ring 6 there is arelative contact plate 10. - Each
contact plate 10 is opposite the supportingring 6 with which it is associated, forming atin 1 containment zone. - According to the embodiment illustrated in Figures 4 and 5, the
contact plate 10 is a disk having a diameter greater than or equal to that of thetin 1 on which beading must be formed and rests uniformly on the whole of theend edge 3 of theupper opening 2. - According to another embodiment illustrated in Figures 1, 2 and 3, the
contact plate 10 has a section with the shape of an inverted "U", where the concave part of the U faces thetin 1 and the ends of theplate 10 rest on theedge 3 of thetin 1. - With this type of plate, when the supporting
ring 6 is in its lowered position and themandrel 7 is inside it, themandrel 7 is inside the portion of space delimited by theplate 10, as shown in Figures 2 and 3. - Advantageously, the
contact plate 10 may have a projectingportion 100 designed to completely fit thetin 1upper opening 2, as illustrated in Figures 2, 3 and 4. - According to another embodiment not illustrated, 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 theedge 3 of thetin 1, said points being symmetrically and uniformly distributed on theedge 3. - As illustrated in Figures 1 and 2, the
contact plate 10 is supported by aplate 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 thetin 1, and a lowered position in which it is in contact with thetin 1. - The
contact plate 10 vertical movement is driven by cam means, of the known type, acting on the supportingplate 11. Figure 1 shows aportion 102 of a cam profile (associated with the carousel 5) engaged by acam follower 103 associated with the supportingplate 11. - The rod-
shaped element 12 comprises abracket 13. Thefirst end 14 of thebracket 13 is rigidly connected to the rod-shaped element 12 by ascrew 15, and thesecond end 16 of the bracket is connected to thecontact plate 10 supportingplate 11 by ascrew 17 andhelical spring 18 connection. - The
contact plate 10 is also connected to the supportingplate 11 by, for example, a ball bearing (not illustrated) and so is able to rotate idly relative to its axis of rotation C (see arrow F10 in Figure 1). - Advantageously, the
contact plate 10 axis of rotation C and thetin 1 axis of rotation B' coincide. - In practice, a
tin 1 on which beading must be formed is fed from atin 1 feed station, as illustrated in Figure 1. - During this step the supporting
ring 6 is in its raised position to receive thetin 1 arriving from the feed station, and therelative mandrel 7 is below the supportingring 6. - During
tin 1 positioning on the ring, thecontact plate 10 is raised to allowtin 1 positioning on thering 6. In this configuration thespring 18 connected to thebracket 13 is compressed. - Once the
tin 1 is positioned on the supportingring 6 and lowering towards themandrel 7 starts, thecontact plate 10 is lowered thanks to the movement transmitted by the cam mechanisms 102 - 103 to the supportingplate 11, to which it is connected. - In its lowering stroke, the
contact plate 10 does not return to its original position, but remains slightly raised, due to the presence of thetin 1. - This means that the
spring 18 does not return to its home position, but remains slightly compressed, consequently applying to the contact plate 10 a downward axial force, with reference to the direction of the arrow F in Figure 2. - 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 thecontact plate 10 deriving from the position imposed on it by the cam mechanism. - Moreover, thanks to its shape, the
contact plate 10 rests on the whole of theedge 3 of thetin 1, consequently applying a uniform pressure on thetin 1 and so preventing even small amounts of axial sliding which would compromise the success of the beading operation. - Once the
contact plate 10 is closed, themandrel 7 is inserted in thetin 1. - During this step the
carousel 5 continued to rotate, bringing the unit consisting of thering 6, themandrel 7, thetin 1 and thecontact plate 10 close to the zone where thebeading sector 8 is located. - The
tin 1 runs along thecircular sector 8, forced against it by the action of themandrel 7. - In practice, the
tin 1 cylindrical body is inserted between theinner surface 101 of thebeading sector 8, having theprojections 9, and the outer surface of themandrel 7, shaped to match theinner surface 101 of thebeading sector 8. - In this way, the beading is formed on the
tin 1, which rolls without slipping along thebeading sector 8 about its own axis of rotation B'. - Advantageously, the
contact 10 plate, able to rotate idly about its own axis C, also rotates with thetin 1, thus preventing theend edge 3 of thetin 1 from being scratched and/or the removal of material or paint from thetin 1. - When the
tin 1 has passed through the whole of the zone corresponding to thebeading sector 8, it is moved towards an unloading station then sent on to subsequent stations. - The invention brings important advantages.
- Firstly, 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.
- Moreover, the 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.
- Another advantage also derives from the fact that the contact plate moves vertically and is not hinged at a single point or on one side.
- This guarantees a good contact plate grip even without the aid of the helical spring, meaning that it does not require difficult adjustments depending on the tin on which beading must be formed.
- The invention described above is susceptible of industrial application and may be modified and adapted in several ways without thereby departing from the scope of the inventive concept. Moreover, all details of the invention may be substituted by technically equivalent elements.
