Abstract
A packaging device for packaging discrete medicaments in pouches that is configured to form and fill the pouches in an elongated web to contain the medicaments comprises a web drive for guiding the elongated web in a transport direction along a web trajectory, wherein the packaging device further comprises a sealing station along the web trajectory, wherein the sealing station is configured to apply a seal to the elongated web to form at least a part of a pouch.
Claims24
A packaging device for packaging discrete medicaments in pouches, the packaging device comprising:
- a web drive for guiding an elongated web of pouches in a transport direction (T) along a web trajectory (P),
- a sealing station along the web trajectory (P), wherein the sealing station is configured to apply a seal in the elongated web to form at least a part of a pouch,
- a driven output roller downstream of the sealing station in the transport direction (T), and
- a control unit that is operationally connected to the sealing station and the web drive, wherein the control unit is configured to perform the steps of:
- a) controlling the web drive to drive the elongate web in the transport direction (T) along a web trajectory (P) at a constant transport torque (T1) of the output roller;
- b) controlling the web drive to cease the transportation of the elongate web and controlling the sealing station to locally apply a seal to the elongate web for forming at least a part of a pouch;
- and
- c) controlling the web drive to drive the output roller at a constant first velocity (V1) to increase the torque back to the transport torque (T1).
(canceled)
The packaging device according to claim 9, wherein the control unit is arranged to drive the driven output roller at a higher circumferential velocity than the driven infeed roller.
The packaging device according to clamp 1, wherein the web drive further comprises a driven infeed roller upstream of the sealing station in the transport direction (T) for feeding the elongate web in the transport direction (T) to the sealing station.
A method for packaging discrete medicaments (M) in pouches, wherein the method comprises the steps of:
- a) guiding an elongate web in a transport direction (T) along a web trajectory (P) at a constant tension with a web drive with an output roller;
- b) releasing tension in the elongate web while locally applying a seal to the elongate web for forming at least a part of a pouch in the elongate web;
- c) tensioning the elongate web by driving the output roller at a constant first velocity (V1) to increase the torque;
- and
- d) transporting the elongate web further in the transport direction (T) along the web trajectory (P) at a constant tension.
