Reorienting device for reorienting simulated cigarette parts which are carried by a product carrier about a vertical product axis from a first angular orientation to a second, predetermined orientation relative to said product carrier, wherein the device comprises: - a main vertical rotation axis; - a first cam track extending at least partially around the main vertical rotation axis; - a rotary carrousel configured to rotate about the main vertical rotation axis, the rotary carrousel comprising; ∘ a rotary support frame; ∘ a plurality of reorienting units connected to the rotary support frame and arranged in a circular configuration when viewed in top view, each reorienting unit comprising an engagement member, wherein each engagement member is configured to engage the simulated cigarette part and to reorient it about a vertical product axis, wherein each reorienting unit comprises a first section which is rotatable relative to the rotary support frame about a vertical unit axis and is movable in a vertical direction between an upper position and a lower position, the upper position being a retracted position and the lower position being an engagement position; ∘ a plurality of transmission mechanisms connected to the rotary support frame, each transmission mechanism being associated with a respective reorienting unit, each transmission mechanism comprising a cam which moves along the first cam track during the rotation of the rotary support frame, wherein the transmission mechanisms convert a movement of the cam into a rotation of the first section of the reorienting unit about the vertical unit axis relative to the rotary support frame; - a moving device for moving the product carriers, the moving device comprising: ∘ a circular track located underneath the reorienting units and configured to guide the product carriers which hold the simulated cigarette parts; ∘ a plurality of product carrier movers for moving the product carriers along the circular track underneath the reorienting units, - a second cam track configured to vertically displace the first section of the reorienting units. - a main vertical rotation axis; - a first cam track extending at least partially around the main vertical rotation axis; - a rotary carrousel configured to rotate about the main vertical rotation axis, the rotary carrousel comprising; ∘ a rotary support frame; ∘ a plurality of reorienting units connected to the rotary support frame and arranged in a circular configuration when viewed in top view, each reorienting unit comprising an engagement member, wherein each engagement member is configured to engage the simulated cigarette part and to reorient it about a vertical product axis, wherein each reorienting unit comprises a first section which is rotatable relative to the rotary support frame about a vertical unit axis and is movable in a vertical direction between an upper position and a lower position, the upper position being a retracted position and the lower position being an engagement position; ∘ a plurality of transmission mechanisms connected to the rotary support frame, each transmission mechanism being associated with a respective reorienting unit, each transmission mechanism comprising a cam which moves along the first cam track during the rotation of the rotary support frame, wherein the transmission mechanisms convert a movement of the cam into a rotation of the first section of the reorienting unit about the vertical unit axis relative to the rotary support frame; ∘ a rotary support frame; ∘ a plurality of reorienting units connected to the rotary support frame and arranged in a circular configuration when viewed in top view, each reorienting unit comprising an engagement member, wherein each engagement member is configured to engage the simulated cigarette part and to reorient it about a vertical product axis, wherein each reorienting unit comprises a first section which is rotatable relative to the rotary support frame about a vertical unit axis and is movable in a vertical direction between an upper position and a lower position, the upper position being a retracted position and the lower position being an engagement position; ∘ a plurality of transmission mechanisms connected to the rotary support frame, each transmission mechanism being associated with a respective reorienting unit, each transmission mechanism comprising a cam which moves along the first cam track during the rotation of the rotary support frame, wherein the transmission mechanisms convert a movement of the cam into a rotation of the first section of the reorienting unit about the vertical unit axis relative to the rotary support frame; - a moving device for moving the product carriers, the moving device comprising: ∘ a circular track located underneath the reorienting units and configured to guide the product carriers which hold the simulated cigarette parts; ∘ a plurality of product carrier movers for moving the product carriers along the circular track underneath the reorienting units, ∘ a circular track located underneath the reorienting units and configured to guide the product carriers which hold the simulated cigarette parts; ∘ a plurality of product carrier movers for moving the product carriers along the circular track underneath the reorienting units, - a second cam track configured to vertically displace the first section of the reorienting units.
