Definitions
- the present invention relates to carousel structures according to the preamble to Claim 1.
- Carousel structures of this type are currently used in the art, for example, for cyclically performing operations such as filling a mould, possibly locating cores in the mould, pouring the casting material into the mould, extracting the moulded piece, etc., by advancing successively in front of work stations located in fixed positions around the carousel structure.
- operations are referred to purely by way of example.
- the carousel structure constitutes a single unit supported on the ground by means of a base with the interposition of an articulation element such as a bearing between the base and the rotary portion of the carousel structure.
- the object of the present invention is to provide a solution which retains the intrinsic advantages of a carousel structure whilst avoiding the problems outlined above.
- this object is achieved by means of a carousel structure, particularly for foundry applications, having the specific characteristics recited in Claim 1.
- a carousel structure for use, for example, in a foundry is generally indicated 1.
- the structure 1 is composed of a plurality of peripheral elements 2, preferably configured in the form of casting machines and connected to a central hub or core 4 by means of respective arms 3.
- the core 4 is usually rotatable about a principal vertical axis X4 which also defines the principal central vertical axis of the carousel structure 1.
- the term "casting machine” used by way of example with reference to the elements 2 indicates an element which can be used for performing the set of operations normally connected with the production of a mechanical element by casting (positioning the moulds, inserting the cores, the actual casting, extracting the moulded item, discharging the mould, etc.).
- At least some of the arms 3 not only perform the function of connecting the elements 2 to the central core 4 but preferably carry associated conveyor lines, generally indicated 5.
- the lines 5, which are at least partially coextensive with the arms 3, enable the so-called servo-means (compressed air, lubricating and cooling fluids, electrical supply, etc.), which are necessary for the operation of the elements 2 and of the members associated therewith, to be supplied from the core 4 towards the elements 2.
- an important characteristic of the solution according to the invention is that the structure 1 according to the invention does not provide for the use of a support member common to all of the moving parts (in particular for the elements 2 and for the core 4) as is the case in solutions with a suspension having a bearing mentioned in the introductory portion of the present description.
- the elements 2 have respective separate and independent means for supporting them in motion.
- this overcomes the rigid connection between the elements 2 and with the core 4.
- an individual element 2 can move independently angularly towards and/or away from the adjacent elements 2.
- This solution may be advantageous since it enables, for example, the time spent by an individual element 2 in the region of a certain station B1, B2, ... no longer to be constrained by the movement between one station and the other; in other words, an element 2 may, for example, be stopped selectively, whilst the adjacent elements are advancing, or vice versa.
- This capability is also advantageous for the purposes of the location of the stations B1, B2, ... which is no longer constrained by a fixed geometry of the carousel structure.
- each of the elements 2 is in practice constituted by a type of carriage mounted on rolling bodies such as wheels or rollers 7, or on equivalent suspension means which support each element 2 independently of the other elements 2.
- rolling bodies such as wheels or rollers 7, or on equivalent suspension means which support each element 2 independently of the other elements 2.
- the elements 2 move on at least one common movement structure such as a rail 8 (preferably, there is a pair of rails forming a track) mounted, possibly with the interposition of a reinforcing and support section P, in a respective pit or channel T formed in the bed on which the structure 1 is mounted.
- a rail 8 preferably, there is a pair of rails forming a track
- one or more rails also enables a toothed structure to be associated with the rail, if this is considered appropriate, so as to provide the elements 2 with a rack drive mechanism.
- the at least partially recessed arrangement of the rail or rails 8 has been found advantageous since it enables the general level of movement of the elements 2 to be lowered.
