Description

DESCRIPTION
CAN SEAMING STATION AND CAN SEAMING PROCESS IN A
SEAMING STATION
Technical field
The present invention relates to a can seaming station and a can seaming process in a seaming station.
Prior art It is known that in a seaming station the cans are brought to a predefined area in which the seaming takes place.
In a solution of the known type, the cans are transported to a seaming area by a transfer starwheel or a conveyor belt with intermittent operation. Disadvantageously, the intermittent movement implies strong jolts for the cans and, as they are not yet sealed, a part of product can come out of the can.
This is frequent especially when the cans contain a liquid product, in particular beer.
In another solution of the known type, the cans are pushed to a seaming area by means of a pusher controlled by a pneumatic cylinder. This makes the thrust imparted to the can difficult to control.
Object of the invention
In this context, the technical task underpinning the present invention is that of proposing a can seaming station and a can seaming process in a seaming station, which obviate the drawbacks of the prior art cited above.
In particular, the object of the present invention is to propose a seaming station and a can seaming process in a seaming station, which enable the cans to be moved without jolts, so as to be able to also treat cans filled with beer. Another object of the present invention is to propose a constructively simple seaming station.
The stated technical task and the specified objects are substantially achieved by a can seaming station and a can seaming process in a seaming station, comprising the technical features disclosed in one or more of the appended claims.
Brief description of the drawings
Further characteristics and advantages of the present invention will become more apparent from the approximate and thus non-limiting description of a preferred, but not exclusive, embodiment of a can seaming station and a can seaming process in a seaming station, as illustrated in the accompanying drawings, of which:
- figure 1 shows a perspective view of a can seaming station, according to the present invention, in a first configuration (transfer member at the feeding belt);
- figure 2 shows a perspective view of the seaming station in a second configuration (transfer member at the seaming station).
Detailed description of preferred embodiments of the invention
With reference to the figures, reference numeral 1 indicates a can seaming station.
The seaming station 1 comprises a seaming area 2. In the embodiment described and illustrated herein, the seaming area 2 is a support that sustains a can below a seaming means (not illustrated being substantially of the known type).
The seaming station 1 comprises a feeding belt 3 for feeding cans according to a conveying direction. The feeding belt 3 has an end 3a side by side to the seaming area 2.
The cans are transferred by the feeding belt 3 to the seaming area 2 by means of a transfer member 4 of single cans. Preferably, the transfer member 4 comprises an element for receiving individual cans. Preferably, the receiving element is substantially U- or C-shaped so as to at least partially surround the body of the single can.
The seaming station 1 comprises a moving means for moving the transfer member 4 between a first position, in which the transfer member 4 is substantially at the feeding belt 3, and a second position, in which it is substantially at the seaming area 2, and vice versa.
Originally, the moving means comprises a cam 5 to which the transfer member 4 is connected for moving it away from/towards the seaming area 2.
Preferably, such cam 5 has a profile such that the transfer member 4 performs rotation and translation movements away from/towards the seaming area 2.
Preferably, the moving means comprises a slide 6 translating alternately in a translation direction substantially perpendicular to the conveying direction. The slide 6 is connected to the transfer member 4 for imparting thereto the translation movement between the first and the second position, and vice versa.
Preferably, an active element is constrained to slide in the cam 5 and is connected to the transfer member 4.
In the embodiment described and illustrated herein, the slide 6 is a pipe 8 sliding on a cylindrical element 9 and rotating around it. The transfer member 4 is rigidly connected to the pipe 8 so as to receive therefrom both the translational motion component and the rotatory motion component. The pipe 8 is connected to the active element. Preferably, the active element is arranged at one end of a rod 10 originating from the pipe 8.
Preferably, the seaming station 1 comprises an unloading belt 11 of the seamed cans.
Preferably, the feeding belt 3 and the unloading belt 11 are arranged on opposite sides of the seaming area 2. Preferably, the unloading belt 11 is side by side to the seaming area 2, on the opposite side with respect to the feeding belt 3.
Preferably, the feeding belt 3 and the unloading belt 11 extend according to two substantially parallel conveying directions.
Preferably, the transfer member 4 is shaped so that, during the movement from the first position to the second position, it transfers a sealed can from the seaming area 2 to the unloading belt 11 . A can seaming process in a seaming station 1 according to the present invention is described below. Such method is advantageously implemented by a seaming station 1 according to what is described above.
The seaming station 1 comprises:
- a seaming area 2;
- a feeding belt 3 for feeding cans according to a conveying direction having an end 3a side by side to the seaming area;
- a transfer member 4 for transferring single cans from the feeding belt 3 to the seaming area 2;
- moving means for moving the transfer member 4 between a first position, in which the transfer member 4 is substantially at the feeding belt 3, and a second position, in which it is substantially at the seaming area 2, and vice versa.
Originally, the moving means moves the transfer member 4 away from/towards the seaming area 2 by means of a composed motion of roto- translation which brings single cans into the seaming area 2.
The transfer member 4 is at the feeding belt 3 for accommodating a can. After this the transfer member 4 moves from the first position to the second position along a substantially rectilinear path for transferring the can to the seaming area 2. Once the can is positioned in the seaming area 2, the transfer member 4 moves from the second position to the first position by means of a roto-translation movement so as not to obstruct the path previously followed.
Preferably, during the movement from the first to the second position, the transfer member 4 transfers a can to be seamed from the feeding belt 3 to the seaming area 2 simultaneously pushing a seamed can, present in the seaming area 2, towards an unloading belt 11 .
From the description provided, the features of the can seaming station and the can seaming process in a seaming station according to the present invention are clear, as are the advantages. In particular, the use of a cam for guiding the motion of the transfer member enables a soft movement of the cans, thus preventing jolts for the cans and precisely controlling the efforts imparted.
Furthermore, the arrangement of the feeding belt and the unloading belt opposite the seaming area and side by side to it enables the seamed can to be transferred during the same movement that takes a can to be seamed to the seaming area.
Furthermore, the fact that the transfer member is controlled by the pipe which is slidably movable on the cylindrical element and rotating about it reduces the components necessary for obtaining the optimal roto- translational movement to a minimum.
