Definitions
- the present invention relates to a method and an equipment for quickly and efficiently assembling link-type jewellery products, e.g. consisting of a link chain structure, such as bracelets/armlets of the type commonly known as TENNIS.
- link-type jewellery products e.g. consisting of a link chain structure, such as bracelets/armlets of the type commonly known as TENNIS.
- Italian patent no. 1383693 describes a product of jewellery or costume jewellery, or the like, made up of a link chain structure forming a bracelet.
- a link chain structure is formed by a plurality of collet elements, arranged side by side according to a repetitive series that develops longitudinally, wherein the collet elements are linked to each other.
- Such a type of bracelets known as tennis, permits the insertion of an ornamental stone, e.g. a precious or semi precious one, on each collet element, which stones seem to be, in the finished bracelet, joined together without solution of continuity.
- an ornamental stone e.g. a precious or semi precious one
- Said Italian patent teaches to make such bracelets by means of collet elements internally delimiting a central cavity or hole and integrally provided, as one piece, with an L-shaped lateral appendage that is inserted into the central cavity of an immediately adjacent collet element, in a downward direction, and then bent against the bottom of the collet element the appendage of which has been folded, thereby obtaining a hinge connection between each pair of adjacent collet elements.
- Such operations are carried out manually by a skilled goldsmith, by inserting and locking the collet elements in a vice, which also allows for proper alignment thereof, by bending the L-shaped appendage with a tool such as pliers, a screwdriver or the like, collet by collet, and then by definitively securing the folded appendages to the bottom of the respective collet elements, which is provided with a suitable receiving seat, by welding, e.g. brazing.
- the invention provides a method and an equipment for making link chain jewellery or costume jewellery products such as, for example, tennis-type bracelets, having the features set out in the appended claims .
- FIG. 1 schematically shows the equipment of the invention, including a first machine and a second machine, the latter being illustrated only in a schematic manner;
- FIG. 2 schematically shows, in a larger scale, the second machine included in the equipment of Figure 1, with some parts removed for a better understanding;
- FIG. 3 and 4 respectively show a three-quarter perspective view from below of a component of the equipment of Figure 1 and a sectional view along a plane IV-IV of the component of Figure 3;
- FIG. 5 shows an exploded perspective view of the first machine of the equipment of Figure 1;
- FIG. 7 shows an exploded perspective view of a second component of the equipment of Figure 1 and, in a larger scale, of a detail thereof.
- numeral 1 designates as a whole an equipment for making link chain jewellery or costume jewellery products, e.g. tennis-type bracelets.
- equipment 1 is useful for manufacturing in a partially automated and simplified manner bracelets and other link chain products as described in Italian patent no. 1383693, the contents of which have been incorporated herein for easy reference.
- a plurality of identical collet elements 2 must be arranged side by side according to a repetitive series that develops longitudinally, to be linked to each other by means of an L-shaped lateral appendage 3, which protrudes in a cantilever fashion from a same first face 4 and on a same side 5 of each collet element 2, extending past, and thus projecting from, a second face 7 of collet element 2 opposite to face 4.
- Appendage 3 protruding in a cantilever fashion from (relative to) face 7 is inserted through a central hole 6 of another collet element 2 immediately adjacent thereto, and is then bent against the second face 7 of the same collet element 2 to which appendage 3 in question belongs.
- respective tips or “legs” 8 of collet element 2 protrude in the same axial direction as that of appendage 3 (relative to hole 6), configured for receiving and interlocking with, when in use, an ornamental stone, which is known and will not be illustrated herein for simplicity.
- Hole 6 is generally a round through hole and is anyway symmetrical with respect to an axis A parallel to the direction of projection of appendage 3 and tips 8.
- Each collet element 2 is delimited, laterally relative to side 5, by a pair of flat side surfaces 9, arranged substantially perpendicular to side 5, which is also defined by a flat surface.
- any link chain product such as a bracelet, a necklace, a pendant, etc.
- This description will refer to the making of a bracelet, but it is clear that the following teachings are also applicable to any other link chain jewellery/costume jewellery product.
- Equipment 1 according to the invention comprises ( Figures 1, 2, 6 and 7) an assembly template 10 for collet elements 2, configured to receive collet elements 2 coupled together two by two according to the above-mentioned repetitive longitudinal series within a channel 11 of adjustable length, to form at the end of the processing, as will be explained hereinafter, a semi-finished product 12 ( Figures 6 and 7) .
- Channel 11 is delimited by two jaws 13b, 13c of assembly template 10.
- Jaws 13 b, c are defined, in the illustrated example, by straight parallelepiped plate elements, and are mounted relatively mobile with respect to each other, one towards the other, e.g. by means of one or more screws (which are known and therefore not illustrated herein for simplicity) that can be coupled to holes 14 ( Figure 7), so as to be able to clamp, on opposite sides, a plurality of collet elements 2 arranged in channel 11 according to the above-mentioned repetitive series by acting against opposite side surfaces 9.
- At least one of jaws 13, in the illustrated example jaw 13b, comprises a surface plate 15 ( Figure 7) configured to receive, resting thereon, collet elements 2 from the side opposite to face 7 from which L-shaped appendage 3 protrudes in a cantilever fashion, i.e. from the side of face 4 and tips 8.
- assembly template 10 is made as a self-supporting unit provided with fastening means 16 for fastening it to a support; fastening means 16 consist of, in the illustrated example, ears 16 formed integrally with the opposite ends of jaw 13b, projecting longitudinally therefrom, and provided with fastening holes 17 ( Figure 7) for suitable screws, which are known and therefore not illustrated herein for simplicity. It is clear that any other fastening means other than ears 16 may also be used; for example, template 10 may be provided with suitable seats for inserting it with a snap action into a support .
- surface plate 15 is not flat ( Figure 7), since it is provided with a toothing 150 comprising a plurality of teeth 151 spaced apart, in a longitudinal development direction of jaws 13b, c, by a pitch or interval P.
- Teeth 151 are present in a number equal to (or possibly larger than) the number of collets 2 to be received in channel 11, and are configured for coupling each between tips or legs 8 of a respective collet 2 arranged with face 4 towards toothing 150 and side surfaces 9 parallel to teeth 151.
- equipment 1 also comprises at least one first machine 18 and at least one second machine 19, which are schematically illustrated together in Figure 1 and intended for sequential operation, but are not necessarily close to each other in actual use.
- Machine 18 is schematically illustrated in the detail of Figure 1 and in an exploded configuration in Figure 5 for a better understanding.

- Press device 24 is provided with an interchangeable die block 26 and stop means 27 for stopping die block 26 in a position in which it is adapted to interfere with lateral appendages 3.
- die block 26 is configured to bend in succession, one at a time, lateral appendages 3 of collet elements 2 pre-coupled according to the above-mentioned repetitive series, as a consequence of the transit of carriage support 22 under die block 26.
- press device 24 comprises: a pair of support feet 28 integrally fixed to the first pedestal 20 on both opposite sides of the first guides 21, which first guides 21 are arranged between support feet 28; a plurality of guiding columns 29 integrally fixed to support feet 28, on top of the same, at a bottom end 30 thereof ( Figure 5) ; a first plate element 31 integrally fixed to a top end of guiding columns 29, opposite to end 30; a second plate element 32 that slidably engages guiding columns 29 and integrally carries at the bottom, in a removable manner, die block 26; and motor means 33 integrally carried by the first plate element 31 and adapted to move the second plate element 32 along guiding columns 29, so as to selectively move it closer to or away from support feet 28.
- Stop means 27 of the die block consist of respective upper ends of support feet 28 ( Figure 5) .
- Motor means 33 are configured to keep the second plate element 32 locked in abutment against upper ends 27 of support feet 28, so as to arrange die block 26 in a first operating position, shown in Figure 1, in which it is adapted to interfere with lateral appendages 3 of collet elements 2.
- Motor means 33 are also configured to selectively move die block 26 into a second operating position, not shown herein for simplicity, in which die block 26 is farther away from carriage support 22 and the second plate element 32 is in proximity to or against the first plate element 31.
- motor means 33 are of a known hydraulic or pneumatic type, but may of course also be of the electromechanical type.
- the second machine 19 ( Figure 2) comprises: a second stationary pedestal 34; respective second straight guides 35 integrally carried by the second pedestal 34; a second carriage support 36, movable along the second guides 35 in a sliding manner with a reciprocating straight motion along a second path T2 having a pre-set length and configured to receive integrally, yet in a removable manner, assembly template 10; second adjustable actuators 37 for moving the second carriage support 36 along the second guides 35 for fractions of motion equal to a centre-to-centre distance or pitch P ( Figure 6) between collet elements 2 coupled two by two according to the above-mentioned repetitive series; and a welding head 38 of any known kind, supported by the second pedestal 34 above the second carriage support 36 and at a first end 39 of the second path T2 facing towards a first end-of-stroke position of the second carriage support 36, shown in Figure 2, wherein the assembly template 10 lies lower than, but not under, welding head 38.
- Collets 2 are assembled with a constant pitch P, due to the fact that they are inserted, one by one, on a respective tooth 151.
- Welding head 38 faces towards the second guides 35 and is configured to weld, one at a time, lateral appendages 3 of collet elements 2 coupled according to the above-mentioned repetitive series, each lateral appendage 3 to respective collet element 2 to which it belongs, as the second carriage support 36 carries along collet elements 2 under welding head 38.
- welding head 38 is a laser welding machine; this selection has proved to be fully satisfactory, in actual use, for automating the welding process, since it has surprisingly demonstrated to be able to effectively weld lateral appendages 3 to the respective collet elements 2 and against face 7 (preferably provided with suitable receiving seats, not shown herein for simplicity) without requiring any filler metal and without resorting to traditional brazing techniques .
- machine 19 comprises also a cover 119 (Figure 1), which covers not only laser head 38, but also carriage support 37 and its driving means; such cover 119 has been removed in Figure 2, but the latter shows an inspection window 120, which, when in use, looks exactly over laser head 38.
- fastening means 16 for fastening assembly template 10 are configured to integrally, and yet removably, couple assembly template 10 to, selectively, the first carriage support 22 and the second carriage support 36.
- stop means 16 consist of seats intended to receive stop ferrules carried by carriage supports 22, 36, with respective guides into which the opposite ends of template 10 are slidably inserted.
- first machine 18 and the second machine 19 can be used in sequence, so that the at least one second machine 19 receives a first assembly template 10 from the at least one first machine 18 after the bending of lateral appendages 3, while the at least one first machine 18 is free to receive a second assembly template 10 different from the first one (not shown for simplicity), provided with collet elements 2 whose lateral appendages 3 are still to be bent.
- an equipment 1 may include only one machine 18 and more (two) machines 19, or vice versa, so as to avoid any downtime.
- each machine 18, 19 may be configured, according to a variant not shown herein, to receive two different templates 10 in succession for doubled productivity, as will be explained hereinafter.
- first and second guides 21, 35 of each first and second machine 18, 19 are defined by opposite longitudinal sides of, respectively, first and second H-beams, respectively designated as 40 and 41, which are integrally fixed to the respective pedestals 20, 34.
- At least the first carriage support 22 (preferably both carriage supports 22 and 36 - the same reference numerals of the components of carriage support 22 have also been used, for simplicity, for carriage support 36) comprises a rigid frame structure 42 H-shaped in a direction parallel to the first guides 21 (guides 35 for carriage support 36) and comprising a first pair of legs 43 that engage the first and, respectively, the second guides 21 and 35, and a second pair of legs 44 configured to support assembly template 10 at respective opposite ends of the latter, which in the non limiting example illustrated herein are provided with ears 16 and are, for carriage support 22 only, substantially flush with stop means 27 of die block 26.
- die block 26 consists of a metal block 26b, in the illustrated example having a parallelepiped shape, provided at the bottom with a longitudinal groove 45 oriented parallel to the first guides 21 and configured to receive, in a through manner, an upper edge 46 of jaws 13b, 13c of assembly template 10.
- Edges 46 of the pair of jaws 13 (13b, 13c) delimit channel 11, which is configured in such a way that at least lateral appendages 3 of collet elements 2 protrude in a cantilever fashion from the same.
- Groove 45 has a first open end 47 facing the side of the first end 25 of the first path T1 and a second open end 48 opposite to the first one and facing a second end 49 of the first path T1 facing towards a second end-of-stroke position (not shown herein for simplicity) of the first carriage support 22, in which assembly template 10 has fully passed under press device 24.
- Groove 45 is centrally equipped with a longitudinal rib 50 extending from the second end 48 of groove 45 towards the first end 47 of groove 45, without however occupying an end stretch 51 thereof immediately adjacent to the first end 47.
- Rib 50 is delimited towards the first end 47 of groove 45 by a first inclined plane 52 that extends from a flat top surface 53 of longitudinal rib 50 towards a bottom wall 54 of longitudinal groove 45, on the side of the first end 47 of the latter.
- Longitudinal groove 45 is internally provided with, at end stretch 51, a pair of lateral projections 55 delimiting a channel 56 in between, aligned with longitudinal rib 50 and configured to slidably receive, inside of it, lateral appendages 3.
- Projections 55 are delimited towards the first end 47 by respective second inclined planes 57 oriented like the first inclined plane 52.
- the mouth of end 47 is provided on both of its opposite lateral flanks with inclined guiding surfaces 58, configured to ensure that assembly template 10 will enter groove 45 and slide therein perfectly aligned therewith .
- the first adjustable actuators 23 consist of: a worm screw 59 carried idle by the first pedestal 20 under the first carriage support 22 and for at least the entire length of the first path Tl; a nut 60, through which worm screw 59 engages, integrally carried by the first carriage support 22, preferably on the side of the first end 25 of the first path Tl; a gear device 61 for rotating worm screw 59, carried by the first pedestal 20; and a driving wheel 62, preferably provided with a handle for manual operation, for actuating gear device 61.
- wheel 62 may be replaced with a suitable known motor.
- Gear device 61 is configured in such a way that its transmission ratio can be changed, if necessary, in a simple and quick manner; for example, it may comprise a gearbox, or it may be configured to allow for quick replacement of one or more gears. In this way it is possible to adjust the revolution speed of worm screw 59 and, as a consequence, the translation speed of carriage support 22.
- gear device 61 is also configured to allow reversing the motion of carriage support 22, so that, when the latter reaches the second end- of-stroke position, it can be brought back into the first end-of-stroke position by reversing the rotation of worm screw 59.
- the return stroke can be used for bending a second series of collets 2, in the aforementioned case wherein carriage support 22 receives in succession two templates 10 mounted in opposite ways and die block 26 has a symmetric configuration .
- the second adjustable actuators 37 consist of: a worm screw 63 carried idle by the second pedestal 34 under the second carriage support 36 for at least the entire length of the second path T2; a nut 64, through which the worm screw 63 engages, integrally carried by the second carriage support 36, preferably on the side of the first end 39 of the second path T2; and an ad ustable-speed, reversible stepper motor 65 for rotating worm screw 63.
- carriage support 36 and worm screw 63 are so designed as to be able to bring carriage support 36 into a second end-of-stroke position (not shown), in which the whole assembly template 10 has passed under welding head 38.
- Stepper motor 65 is controlled by a programmable control unit 650, e.g. consisting of a PLC, carried by pedestal 34.
- the invention also relates to a method for making link chain jewellery or costume jewellery products, e.g. tennis-type bracelets, wherein a plurality of collet elements 2 identical to one another are arranged side by side according to a repetitive series that develops longitudinally, so as to be linked together by means of an L-shaped lateral appendage 3 protruding in a cantilever fashion from a same face 7 and on a same side 5 of each collet element 2, which is first inserted through a central hole 6 of another collet element 2 immediately adjacent thereto and then bent against face 7 of collet element 2 to which the appendage belongs.
- the method of the invention comprising the steps of: a)- making an assembly template 10 for collet elements 2, formed by a pair of relatively mobile jaws 13b, 13c delimiting in between a channel 11 of adjustable width, a bottom wall of which is defined by a surface plate 15 integrally carried by at least one of jaws 13; assembly template 10 being implemented as a self-supporting unit provided with fastening means 16 for fastening it to a support, and surface plate 15 being provided with a toothing 150 having a pitch P;
- collet elements 2 one by one, into said channel 11, coupling them according to said repetitive longitudinal series, said collet elements 2 resting on surface plate 15 on the side opposite to face 7 from which L-shaped appendage 3 protrudes in a cantilever fashion, and inserting the latter into central hole 6 of an immediately adjacent collet element 2, taking care of coupling each collet element 2 with a respective tooth 151 of toothing 150;
- lateral appendages 3 occurs because of the linear transit of assembly template 10 under die block 26, and in particular because of the combined presence of rib 50, projections 55 and inclined planes 52 and 57 within longitudinal groove 45, which receives through it template 10 with appendages 3 protruding upwards in a cantilever fashion, thus ensuring a perfect and correct bending, better than that obtainable manually, since it is sufficient that an operator turns driving wheel 62.
