Definitions
- the present invention relates generally to an apparatus and method for supporting a preforms and more particularly to an apparatus and method that can accommodate preforms having different dimensions.
- a preform support device is used to secure a preform in place so that the preform can be moved.
- Preform support devices can be coupled together in an endless chain for transferring preforms.
- a preform transfer chain consisting of such devices is found especially in plants for manufacturing containers, such as bottles, flasks or the like, made of a plastic, especially a thermoplastic such as polyethylene terephthalate (PET).
- a transfer chain formed in this way is used to move the preforms from a charging station up to and through a heating oven (tunnel oven) in which the perform material is heated for su sequent molding, by a blow molding or stretch-blow molding process, into a large container (either the final container or an intermediate container).
- a heating oven tunnel oven
- Such a transfer chain is described in U.S. Patent Number 5,316,127 which is incorporated herein by reference.
- a preform support device that can be coupled together one after another to form the transfer chain is described in U.S. Patent Number 5,857,562 which is incorporated herein by reference.
- Such a preform support device is shown in Figure 1.
- the device 1 includes a hollow body fixed to a mounting plate 2.
- the body 1 fixed to a mounting plate 2.
- a rod 5 is supported so as to rotate freely in the hollow body 4. Sleeves are provided inside the hollow body 4 to guide the rod. The rod 5 is capable of being moved axially. A spring 6 is provided to return the rod 5 to its starting position. At its free end, the rod
- a gripping head 7 designed to be removably or releasably fastened to the open end of a preform 8.
- the gripping head 7 can be frictionally pressed into the opening of a preform 8.
- the gripping head 7 is typically sized to be substantially the same size as or slightly larger than the interior diameter of the opening of the preform. The gripping head 7 is then compressed and secured within the open end of the preform. It is important that the size of the gripping head and the size of the opening in the preform match each other. Otherwise, the gripping head may be too large and will not fit into the opening of the preform or the gripping head may be too small and will not frictionally engage the preform.
- each gripping head can only be used with a particular size preform or preforms having openings within a very limited range, typically no variation of .006 inches and beyond. [0005] Consequently, in order to use the prior art preform support device or preform transfer chain for preforms of different sizes, the production line must be shut down so that the appropriately sized preform support device for the different sized preforms can be installed. Obviously, this causes a significant delay in production time and a corresponding increase in production cost. Moreover, many different types of prefonn support devices are required to fit the many different types and sizes of bottles that may be manufactured. Therefore, there is a need for a preform support device than can accommodate multiple size preforms and that eliminates the need for changing over the production line.
- an apparatus for supporting a preform comprises a shaft defining a groove.
- a deformable element is arranged in the groove.
- a split ring including at least two sections is provided. Each of the sections has an inner surface facing the deformable member and an outer surface. At least one of the sections has a protrusion extending from its inner surface. The protrusion is arranged adjacent to the deformable element.
- the split ring is moveable in a radial direction whereby the protrusion can cause the deformable element to be compressed in the groove.
- a multiple finish spindle is provided.
- the spindle includes a spindle body defining a groove therein.
- a shell includes at least two pieces disposed around the spindle body.
- the shell has an outer surface, an inner surface facing the spindle body, and a protruding element arranged on the inner surface.
- An elastically deformable element is disposed in the groove.
- the shell is moveable between an uncompressed position and a compressed position in which the shell moves in a radial direction towards the spindle body and the protruding element acts on the deformable element, compressing it in the groove.
- a support device comprising a shaft defining a groove, a deformable element arranged in the groove, and a split ring having at least two pieces, at least one of the pieces having a protrusion extending from an inner surface is provided.
- the support device is inserted into a first preform having a first diameter thereby causing the split ring to be compressed a first distance.
- the support device is removed from the first perform and is inserted into a second preform having a second diameter smaller than the first diameter thereby causing the split ring to be compressed a second distance which is greater than the first distance.

- the split ring 20 the bears on the interior surface 23 and the sections of the split ring 20 are moved radially inward.
- the protrusion 26 is received within the groove 14 and compresses the deformable member 16.
- the elastic properties of the deformable member 16 in turn react against the force of the protrusion 26 and force the split ring 20 radially outward to frictionally engage the interior surface 23 of opening 12.
- the preform support device is frictionally engaged with the preform 8.
- the split ring is move radially inward to a greater extent than in the example shown in Figure 4.
- the protrusion 26 allows the split ring 20 to expand and compress to a greater extent and engage a variety of performs of different sizes.
- the split ring 20 may be compressed until the inner surface 24 of the split ring 20 abuts the shaft 10.
- the size and characteristics of the protrusion 26, groove 14, and deformable member 16 can define the extent to which split ring 20 can move radially inward.
- a preform support device having the design described above can accommodate preforms that have an internal diameter ranging from slightly smaller than the outer diameter of the preform support device when the split ring is uncompressed to a diameter that is slightly larger than the outer diameter of the preform support device when the split ring is fully compressed.
- the device can accommodate variations of greater than about .006 inches in the size of perform openings, and also variations greater than about .012 inches.
- the size of the gap between the split rings, the extent to which the protrusion extends from the back surface of the split ring, and the characteristics of the deformable members can all be dimensioned and selected as necessary for a particular application.
- a preform support apparatus that can accommodate preforms having openings of varying diameters is provided.
- the preform apparatus automatically adapts to the size of the opemng of the preform. There is no need to stop the production line and retool in order to be able to change production from one product to another.
