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.
Claims21
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),
- wherein the control unit is arranged to reverse the direction of the output roller during step b) to reduce the torque on said output roller.
