Definitions
- This invention relates to a method and apparatus for reforming the base of a container.
- it relates to a method and apparatus for reforming the base profile of a can having a one-piece can body used for packaging carbonated beverages .
- Such so-called “beverage cans” typically comprise a side wall, a transition region and a base including a stand bead, an annular inner wall and a substantially dome-shaped centre panel.
- the base formed by the dome station usually has a radially inwardly tapering inner wall for ease of removal from the domer.
- this inner wall at least to a vertical profile or, more usefully, to a negative angle, or a hooked or beaded profile.
- dome growth is thus a particular problem when the can needs to withstand pasteurisation pressures, such as is the case when the product is beer, for example.
- Dome reversal pressure is the pressure at which internal pressure from a carbonated beverage, for example, will cause the dome- shaped centre panel to reverse its shape completely from externally concave to externally convex.
- Internal base profile reforming involves the direct application of a roll against the inner wall so as to reform part or all of that wall to a specific new profile.
- Internal base profile reforming tooling which is currently available uses complex mechanisms which have a very high rate of wear. This wear is particularly costly in terms of replacement tool parts and, if components are not replaced, will lead to variability in the very profile which is critical to the can's performance. Furthermore, because the tooling is complex, there are typically adjustments which need to be made in the factory to maintain consistency of the reformed profile.
- This invention seeks to provide a solution to these problems which may be used for both internal and external base profile reforming.
- an apparatus for reforming the base profile of a can comprising: a roller for forming a desired new profile on the can base; and first and second concentric shafts, the first shaft rotating the roller relative to the can, and the second shaft actuating the roller to move radially to engage the can when there is a speed differential between the shafts.
- the shafts rotate in the same direction. Since the apparatus uses continuous rotation in the same direction instead of forward and back as in known base reforming apparatus, the mechanism is very simple. By using full rotation, there is no setting required by the factory and the reformed profile is more consistent and the apparatus exhibits less wear.
- the apparatus further comprises a cam or an eccentric for actuating the roller to move radially.
- the cam or eccentric may be fixed to the second shaft and one or more cam followers may be mounted on the first shaft. Such mounting may be directly or indirectly.
- the cam follower or followers is/are fixed to a support block which is attached to the first shaft via linear bearings.
- the apparatus is one of a plurality of base profile reforming apparatus each of which is fixed at stations around a rotatable turret machine.
- the first shaft rotates +/- two rotations relative to the second shaft in one machine rotation.
- the first shaft may rotate at six times machine speed and the second shaft may rotate at four times machine speed, or vice versa .
- the actual machine speed is not relevant to the invention. What is essential to the radial movement of the roller is the differential speed between the two shafts .
- the cam is shaped to control the radial movement of the roller so that there is no need for a separate end stop component, for example.
- the apparatus may be used for either internal or external base profile reforming.
- a method of reshaping the base profile of a can comprising: providing a roller for forming a desired new profile on the can base; providing first and second concentric shafts; rotating the roller relative to the can by means of the first shaft; actuating the roller to move radially to engage the can by driving the first and second shafts at different speeds.
- Figure 1 is a side section of internal base profile reforming apparatus
- Figure 2 is a side section of the apparatus of figure 1, at right angles to the side section of figure
- FIG. 3 is enlargement III of figure 1;
- Figure 4 is a transverse section through the line IV-IV on figure 3;
- Figure 5 is a trnasverse section through the lije V- V on figure 3;
- Figure 6 is a 180° timing layout of a turret machine showing the apparatus at 30° positions around the turret.
- Figures 1 to 5 show an apparatus for internal base profile reforming of a beverage can having a domed base.
- the apparatus comprises a base support 1 for supporting a can (not shown) and a profiled roller 5 for reforming the internal base profile.
- Shafts A and B are concentric, a support block 6 holding the reform roller 5 and being joined to the end of shaft A by linear bearings 7, 8.
- the drawings show the linear bearings as linear ball bearings. Alternative bearings such as crossed roller bearings may be ideally used.
- a cam 10 is mounted on inner shaft B and rotates between cam followers 12, 14 which are in turn mounted on the support block 6. Concentric shafts A and B are connected to gears A' and B' respectively.
- the apparatus is surrounded by a housing 9.
- Profiled roller 5 is rotated about the can centre by shaft A and gear A to reform the internal base profile.
- the can remains stationary, although this is not essential to the invention.
- gears A' and B' drive shafts A and B respectively to rotate.
- shafts A and B will rotate in the same direction but at different speeds. Since the cam 10 is fixed to shaft B, cam 10 rotates at the same rotational speed as shaft B.
- the reformed can shape is set in the tooling. There is therefore no factory setting to be made. Continuous rotation of the shafts and rolling rather than sliding contact reduces wear in comparison with known base profile reformers. Further simplification of the cam design can be made by adding compliance to either or both cam followers. Typically spring loading of the return cam follower against the cam is appropriate.
