The tooling is provided at a tooling station which is adjacent the holding station during deformation. The predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the holding station.
1. A method of deforming thin walled bodies to co-ordinate with a pre-applied design on the wall of the bodies, the method comprising:
(i) loading the bodies to be gripped securely in respective clamps of a holding table, the holding table being positioned adjacently opposite a tooling table having a plurality of tooling stations arranged to perform different deformation operations on the bodies, the tooling table and the holding table being rotationally indexable with respect to one another to bring the bodies successively to different tooling stations; and
(ii) whilst gripped in the respective clamp of the holding table, at a coordinated deformation tooling station engaging tooling to deform the peripheral wall of the body at a predetermined wall zone co-ordinated with the pre-applied design;
wherein the predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the clamp of the holding table, without rotationally driving the clamp to effect co-alignment of the pre-applied design with the tooling for deformation.
the body is gripped non rotatably at the holding table.
the tooling of said coordinated deformation tooling station is advanced relative to the holding table, such that an internal deformation tooling part is inserted into the interior of the body and an external deformation tooling part is positioned externally of the body whilst the body is gripped securely at the holding table; and the internal and external deformation tooling parts are operated to engage with and deform the peripheral wall of the body at a predetermined wall zone whilst the body is gripped in a fixed orientation in the holding table; wherein the predetermined wall zone is co-aligned with the tooling of the coordinated deformation tooling station by rotation of the body about an axis prior to securing at the holding table in said fixed orientation for deforming of the wall of the body.
the holding table comprises a multi-station holding table and the coordinated deformation tooling station is part of a multi-station tooling table, the multi-station tooling table and the multi-station holding table being rotationally indexable relative to one another to bring the bodies in succession to the coordinated deformation tooling station.
the body is optically viewed to determine orientation of the body relative to a datum and subsequently rotated about said axis to a datum orientation.
with the body in the datum orientation, the body is inserted into a clamp of the holding table.
7. Apparatus for deforming thin walled bodies to co-ordinate with a pre-applied design on the wall of the bodies, the apparatus comprising:
(i) a holding table having a plurality of holding stations for holding the bodies gripped securely in a respective clamp of the respective holding station;
(ii) a tooling table positioned adjacently opposite the holding table and having a plurality of tooling stations arranged to perform different deformation operations on the respective bodies, the tooling table and the holding table being rotationally indexable with respect to one another to bring the bodies successively to different tooling stations, the tooling table having a coordinated deformation tooling station including tooling arranged to engage with and to deform the body at a predetermined wall zone on the peripheral wall co-ordinated with the pre-applied design whilst the bodies is gripped securely in the respective clamp of the respective holding station, the coordinated deformation tooling station being positioned at a location adjacent the respective holding station and advanced relative to the respective holding station for deformation of the body;
(iii) determination means for determining the orientation of the body relative to a reference datum situation; and
(iv) means for co-ordinated movement to reconfigure the bodies about an axis of the bodies to accord with the datum situation prior to the bodies being gripped at the respective clamp of the respective holding station in a fixed orientation for deforming of the wall of the body, and without rotationally driving the clamp to effect co-alignment of the pre-applied design with the tooling of the coordinated deformation tooling station for deformation.
the respective holding table is configured to grip the body non-rotatably.
the tooling of the coordinated deformation tooling station comprises an internal tooling part and an external tooling part arranged to engage within the interior and exterior of the body respectively.
i) the holding table comprises a multi-table holding table having holding stations each comprising a respective clamp for clamping securely a respective body; and
ii) the tooling table comprises a multi-table tooling table having the coordinated deformation tooling station, the multi-station tooling table being positioned adjacent the multi-station holding table, the multi-station tooling table and the multi-station holding table being rotationally indexable relative to one another to bring the bodies in succession to the coordinated deformation tooling station for coordinated deformation, the multi-station tooling table being advanceable relative to the multi-station holding table, the coordinated deformation tooling station including an internal tooling part and an external tooling part arranged to engage within the interior, and on the exterior, of the body respectively, together to deform the body at a predetermined wall zone on the body with reference to a pre-applied design on the wall of the body, whilst the body is clamped securely in the respective holding table.
11. Apparatus according to claim 7, further comprising:
optical viewing means to determine the orientation of the body relative to the datum situation.

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a continuation of U.S. application Ser. No. 10/182,643, filed Sep. 30, 2002, now U.S. Pat. No. 7,003,999, which is related to PCT Application No. PCT/GB01/00526, filed Feb. 9, 2001, G.B. Application No. 0003033.8, filed Feb. 10, 2000, and G.B. Application No. 0026325.1, filed Oct. 27, 2000, all of which are incorporated herein by reference in their entireties.
SUMMARY OF THE INVENTION An improved technique has now been devised.
i) a holding station for holding the body gripped securely; ii) a tooling station including tooling to deform the body at a predetermined wall zone of the body, the tooling station being positioned at a location adjacent the holding station during deformation; iii) determination means for determining the orientation of the cylindrical body relative to a reference (datum) situation; iv) means for co-ordinated movement to reconfigure the tooling to co-align with the predetermined wall zone prior to deforming engagement of the tooling with the body.
Co-alignment of the tooling and the wall zone of the body is typically required in order to ensure that embossing deformation accurately lines up with pre-printed decoration on the body. In the technique of the present invention, the body is not passed from being supported at a holding station to being supported by the tooling but, by contrast, remains supported at the holding station throughout the deforming process.
inserting internal tooling into the interior of the container, the internal tooling being in a first, insertion configuration for insertion; moving the tooling to a second, (preferably expanded) position or configuration closely adjacent or engaging the internal container wall so as to facilitate deformation of a wall zone of the container; returning the tooling from the second position toward the first tooling configuration thereby to permit retraction of the internal tooling from the container.
Because the internal tooling is movable toward and away from the container wall (preferably toward and away from the axis/centreline of the container), embossed relief features of greater depth/height can be produced. This is because prior art techniques generally use an internal tool which also serves to hold the container during deformation (embossing) and therefore typically only slight clearance between the internal tool diameter and the internal diameter of the container has been the standard practice.
BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be further described in a specific embodiment, by way of example only, and with reference to the accompanying drawings, in which:
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings the apparatus and technique is directed to plastically deforming (embossing or debossing) the circumferential wall of an aluminium container 1 at a predetermined position relative to a preprinted decorative design on the external container wall. Where the embossing deformation is intended to coincide with the printed decorative design, this is referred to in the art as Registered Embossing.
The internal mandrel 15 is expandible to move the tooling parts 11 a, 11 b to a relatively spaced apart position in which they abut the internal wall of the container 1 (see FIG. 12) from the collapsed position shown in FIG. 11 (tools 11 a, 11 b spaced from the internal wall of the container 1). An elongate actuator rod 16 is movable in a longitudinal direction to effect expansion and contraction of the mandrel 15 and consequent movement apart and toward one another of the tool parts 11 a, 11 b. A the cam head portion 17 of the actuator rod 16 effects expansion of the mandrel 15 as the actuator rod 16 moves in the direction of arrow A. The cam head portion 17 acts against sloping wedge surfaces 65 of the tool parts 11 a, 11 b to cause expansion (moving apart) of the tool parts 11 a, 11 b. The resilience of arms 11 biases the mandrel 15 to the closed position as the rod 16 moves in the direction of arrow B.
