Claim 4

A device for moving products in an axial direction thereof, the products being cigarettes supplied to a filter cigarette manufacturing system or filter cigarettes produced in the system, said device comprising: a rotatable grooved drum having an outer peripheral surface adapted to transport the products in a direction perpendicular to the axial direction thereof while rotating; a rotating member located on one side of said grooved drum at a distance therefrom, an angle being secured between the respective axes of said rotating member and said grooved drum; coupling means for rotating said rotating member and said grooved drum at equal speeds, said coupling means including a bellows coupling said rotating member and said grooved drum and transmitting a torque from one of said rotating member and grooved drum to the other while maintaining the angle between the axes of said rotating member and said grooved drum; and a pusher member fixed to said rotating member and extending from said rotating member to a position right over the outer peripheral surface of said grooved drum, said pusher member pushing out the products, being transported on said grooved drum, in the axial direction thereof when a predetermined rotational angle region of said grooved drum is reached by the products on said drum.

Claim 12

A device for separating two aligned products in the axial direction thereof to form a space between the products, the products being cigarettes supplied to a filter cigarette manufacturing system or filter cigarettes produced in the system, said device comprising: a first fixed shaft; a pair of first conical drums rotatably mounted on said first fixed shaft and directed opposite to each other, said first conical drums being adapted individually to receive the two axially aligned products to be separated and transport the products when rotated in the same direction, and respective axes of rotation of said first conical drums being including opposite to each other against the axis of said first fixed shaft so that the products transported by means of said first conical drums are separated from each other; a first rotor member mounted coaxially on said first fixed shaft so as to be rotatable in one direction, said first rotor member being located beside said paired first conical drums, and an angle being secured between the respective axes of said first rotor member and one of said first conical drums which adjoins said first member; first coupling means for rotating said paired first conical drums and said first rotor member at equal speeds, said first coupling means including a pair of first bellows for making connections between said first rotor member and the one first conical drum and between said paired first conical drums and exclusively transmitting a rotatory force from said first rotor member to the one of said paired first conical drums and the one first conical drum to the other first conical drum while maintaining the angles between the axes of said first rotor member and the one first conical drum and between the axes of said paired first conical drums, individually; a second fixed shaft parallel to said first fixed shaft; a pair of second conical drums rotatably mounted on said second fixed shaft and directed opposite to each other, said second conical drums being adapted individually to receive the two products from said paired first conical drums and transport the products when rotated in the direction opposite to said first conical drums, and the respective axes of said second conical drums being inclined opposite to each other against the axis of said second fixed shaft so that the two received products are further separated and aligned again on the same axis with each other; a second rotor member mounted coaxially on said second fixed shaft so as to be rotatable in the direction opposite to that of said first rotor member, said second rotor member being located beside said paired second conical drums, and an angle being secured between the respective axes of said second rotor member and one of said second conical drums which adjoins said rotor member; and second coupling means for rotating said paired second conical drums and said second rotor member at equal speeds, said second coupling means including a pair of second bellows for making connections between said second rotor member and the one second conical drum and between said paired second conical drums and exclusively transmitting a rotatory force from said second rotor member to the one of said paired second conical drums and the one second conical drum to the other second conical drum while maintaining the angles between the axes of said second rotor member and the one second conical drum and between the axes of said paired second conical drums, individually.

Claim 13

A device for separating two aligned products in the axial direction thereof to form a space between the products, the products being cigarettes supplied to a filter cigarette manufacturing system or filter cigarettes produced in the system, said device comprising: a first fixed shaft; a pair of first conical drums rotatably mounted on said first fixed shaft and directed opposite to each other, said first conical drums being adapted individually to receive the two axially aligned products to be separated and transport the products when rotated in the same direction, and respective axes of rotation of said first conical drums being including opposite to each other against the axis of said first fixed shaft so that the products transported by means of said first conical drums are separated from each other; a first rotor member mounted coaxially on said first fixed shaft so as to be rotatable in one direction, said first rotor member being located beside said paired first conical drums, and an angle being secured between the respective axes of said first rotor member and one of said first conical drums which adjoins said first member; first coupling means for rotating said paired first conical drums and said first rotor member at equal speeds, said first coupling means including a pair of first bellows for making connections between said first rotor member and the one first conical drum and between said paired first conical drums and exclusively transmitting a rotatory force from said first rotor member to the one of said paired first conical drums and the one first conical drum to the other first conical drum while maintaining the angles between the axes of said first rotor member and the one first conical drum and between the axes of said paired first conical drums, individually; a second fixed shaft parallel to said first fixed shaft; a pair of second conical drums rotatably mounted on said second fixed shaft and directed opposite to each other, said second conical drums being adapted individually to receive the two products from said paired first conical drums and transport the products when rotated in the direction opposite to said first conical drums, and the respective axes of said second conical drums being inclined opposite to each other against the axis of said second fixed shaft so that the two received products are further separated and aligned again on the same axis with each other; a second rotor member mounted coaxially on said second fixed shaft so as to be rotatable in the direction opposite to that of said first rotor member, said second rotor member being located beside said paired second conical drums, and an angle being secured between the respective axes of said second rotor member and one of said second conical drums which adjoins said rotor member; and second coupling means for rotating said paired second conical drums and said second rotor member at equal speeds, said second coupling means including a pair of second bellows for making connections between said second rotor member and the one second conical drum and between said paired second conical drums and exclusively transmitting a rotatory force from said second rotor member to the one of said paired second conical drums and the one second conical drum to the other second conical drum while maintaining the angles between the axes of said second rotor member and the one second conical drum and between the axes of said paired second conical drums, individually.
