PREFERRED CONSTRUCTIVITY OF THE INVENTION

Figures 1A-7A and 1C-7C illustrate the steps of the usual known prior art two-piece can manufacturing processes, while Figures 1B-8B and 1D-8 illustrate the two-piece can manufacturing processes that illustrate the process. EXPANSION PROCESS FOR CONFORMING TWO-PIECE METAL PACKAGING AND EQUIPMENT EXPANSION PROCESS FOR CONFORMING TWO-PIECE METAL PACKAGING Here we can demonstrate the savings generated by adopting the expansion process illustrated in Figures 1B-8D and 1D-8B and 1D-8B. conventional method illustrated in Figures 1A-7A and 1C-7C; Regarding the utilization and economy of raw materials, which is in the order of approximately 3%, which is considerable if the absolute number of cans produced is evaluated, and this economy is due to the increase in the volume of can bodies after expansion.

Among the innovative features of the present process, illustrated in figures 1B-8B and 1D-8D, we highlight the possibility of creating numerous shapes for two-piece cans, which until now was not possible. This diversification of forms and presentations will allow the creation and exposure of the product identity in the market, making it possible to print the brand, signs and other forms of low or high relief that identify the product in its own tin format.

Another feature is the possibility of creating reliefs and indications for the visually impaired, which can be guided by the reliefs or the identity of the product itself, through the shapes adopted in the body of the can.

The processes illustrated in figures 1B-8B and 1D-8D use expansion systems, which may be by means of demandril, nuts, rulers, tweezers, compressed air, water and oil between others, where obtaining the expanded can, associated with the production of the can The two-part operation is carried out in six operations or stages, using specific equipment for the expansion operation, which may or may not be interconnected in production.

The first step, which is the feeding of the coils and the cutting and stamping of the can cup as shown in (Figs. 1A, 1B, 1C, 1D) are the same for all processes.

The second step, where can stamping and bottom forming, shown in (Figs. 2A, 2B, 2C, 2D) are also the same for all processes. After the formation of the dalata bottom (figs. 3A, 3B, 3C, 3D), the processes are distinguished, that is, in the conventional process, represented by figures 1A-7A in the third stage, the cutting of the upper excess of the can where the refill is made can (fig. 4A).

In the third step of process 1B-8B the expansion process of the two-piece can body is initiated by the chosen system (Fig. 4B), which operation is not provided for in process 1A-7A.

In the fourth step of process 1A-7A the decoration of the can is done (fig. 6A), while in 1B-8B there is the cutting of the upper excess of the can where the can is refiled (fig. 5B).

In the fifth stage of process 1A-7A, the neck and flange formation process in the can (Fig. 7A) is performed, ending the operations, while in process 1B-8B the dalata decoration (Fig. 7B) is performed.

In the sixth step of the process 1B-8B, the neck and flange formation process in the can is performed (Fig. 8B), ending the operations.

In process 1C-7C, the third step is for the excess can of the upper part of the can, that is, the can refill (fig.4C), and in process 1D-8D, in the third step also can refill ( Fig. 4D).

The fourth step of process 1C-7C is the dalata decoration (fig. 6C), and in process 1D-8D the fourth step is also decoration (fig. 6D).

In the fifth step of the process 1C-7C, the neck and can flange are formed (fig. 7C), ending the operations.

In the fifth step of the process 1D-8D the neck and flange of the can are also formed (Fig. 7D) and then sent to the expansion station.

In the sixth step of process 1D-8D, the process of expanding the two-piece can body (Fig. 8D) is initiated by the chosen system which is not foreseen in process 1C-7C.

After the first and second stages, where the cup cutting and stamping and can stamping and two-piece can body formatting operations are performed in process 1B-8B, shown by (fig.4B), and after Fifth step, neck and flange formation operation in can, in process 1D-8D, shown by (Fig. 8D), the can body (1) is transported via the conveyor system (2) to the entrance of the apparatus (3 ).

From this stage, the can body expansion process (1) is initiated by the chosen system which enters the machine by means of an endlessly threaded conveyor system (4) which rotates synchronously by means of gear (5), with the inlet star (6), through the cardan shaft (14) and rectangular gearbox (15), and through this timing, the can body (1) will be transferred from the endless thread (4) to the input star (6), which are enqueued, being admitted one by one by the machine, whereby through this same timing, by means of gears (8), the can body (1) is transferred to the expansion station ( 7); this transfer occurs from the input star (6) to the expansion station (7) precisely, both of which rotate about their own axis, which allows the can body to be continuously and individually admitted, with at this station (7) expansion occurs, where the can body acquires its final shape, which can varying in function of the system and tooling used (12), whereby, by the same type of timing, by means of gears (10 and 11), the expanded can body is transferred from station (7) to an output conveyor (13). ), by means of an outgoing star (9) which rotates about its own axis, but in the opposite direction of the station (7), which allows the removal of the already duly shaped can body, continuously and individually, of a frequency to the can manufacturing process through successors.
