Abstract

The object of the invention is a forming and transporting apparatus for conveying rod-like articles and for forming groups of the rod-like articles of the tobacco industry, comprising transport units, whereas a transport unit comprises a transport carriage adapted to move along a path, and a transport tray provided with a number of transport grooves adapted to hold the rod-like articles, whereas the tray is fastened to the transport carriage, whereas the transport tray is divided into two transport sections which are adapted to change the reciprocal position between an open configuration in which the transport grooves are situated substantially in one plane and a closed configuration in which the transport grooves are situated in two planes being substantially parallel to each other.

First claim

The invention claimed is:

1. A forming and transporting apparatus ( 5 ) for conveying rod-like articles ( 3 ) and forming a group (G) of rod-like articles ( 3 ) of the tobacco industry, comprising
transport units ( 15 ), whereas a transport unit ( 15 ) comprises
a transport carriage ( 16 ) adapted to move along a path ( 17 ), and
a transport tray ( 13 ) provided with a number of transport grooves ( 18 ) adapted to hold the rod-like articles ( 3 ), whereas such tray is fastened to the transport carriage ( 16 ),
whereas
the transport carriage ( 13 ) is divided into two transport sections ( 13 A, 13 B) which are adapted to change their reciprocal position between an open configuration in which the transport grooves ( 18 ) are situated substantially in one plane (k, k′) and a closed configuration in which the transport grooves ( 18 ) are situated in two planes (k, k′) being substantially parallel to each other,
whereas
the transport sections ( 13 A, 13 B) are rotatably connected with each other on the axis of rotation ( 20 ) corresponding to the direction (T) of movement of the transport carriage ( 16 ), characterised in that
the first transport section ( 13 A) is fastened to the transport carriage ( 16 ), and the second transport section ( 13 B) is provided with a steering element ( 23 ),
the forming and transporting apparatus ( 5 ) is provided with a forming unit ( 25 ) comprising a closing cam ( 24 ) situated next to the path ( 17 ), the closing cam ( 24 ) having a raceway ( 24 C) adapted to guide the steering element ( 23 ) in such a way that while moving the transport unit ( 15 ) through the forming unit ( 25 ) the second transport section ( 13 B) makes a rotation relative to the first transport section ( 13 A) in order to change the configuration of the transport sections ( 13 A, 13 B) from the open configuration to the closed configuration,
characterised in that the body ( 27 ) of the second tray ( 13 B) is provided with at least one vacuum channel ( 28 ) being in fluid connection with vacuum openings ( 19 ) in the transport grooves ( 18 ) of the second transport section ( 13 B), whereas the vacuum channel ( 28 ) is directed towards the cylindrical surface ( 31 ) provided with openings ( 30 ) which supply the vacuum during the movement of the transport unit ( 15 ) through the forming unit ( 25 ).

2. The apparatus as in claim 1 characterised in that the closing cam ( 24 ) has a cylindrical form.

3. The apparatus as in claim 1 characterised in that the steering element ( 23 ) is a rotating roller.

4. The apparatus as in claim 1 characterised in that the cylindrical surface ( 31 ) is a stationary surface.

5. The apparatus as in claim 1 characterised by being provided with an opening unit ( 53 ) comprising an opening cam ( 54 ) situated next to the path ( 17 ), the opening cam ( 54 ) having a channel adapted to guide the steering element ( 23 ) in such a way that while moving the transport unit ( 15 ) through the opening unit ( 53 ) the second transport section ( 13 B) makes a rotation relative to the first transport section ( 13 A) in order to change the configuration of the transport sections ( 13 A, 13 B) from the closed configuration to the open configuration.

6. The apparatus as in claim 1 characterised in that the transport units ( 15 ) are adapted to move along the path ( 17 ) independently of one another.

7. A feeding apparatus for feeding a group (G) of rod-like articles comprising at least one feeding unit ( 4 ) for feeding the rod-like articles ( 3 D) provided with a drum conveyor ( 12 ); at least one forming and transporting apparatus ( 15 ) for receiving the rod-like articles ( 3 ) from the drum conveyor ( 11 ), conveying the rod-like articles ( 3 ) and forming the groups (G) of the rod-like articles ( 3 ); a conveyor ( 6 ) of groups of the rod-like articles ( 3 ) for receiving the groups (G) of the rod-like articles from the forming and transporting apparatus ( 5 ) and feeding the groups (G) to a receiving apparatus; a transferring unit ( 7 ) for transferring the groups (G) of the rod-like articles ( 3 ) from the transport units ( 15 ) to the pockets ( 40 ) of the conveyor ( 6 ) of the groups of rod-like articles, characterised in that
the feeding apparatus is provided with the forming and transporting apparatus described in claim 1 .
