Definitions

  • the present invention relates to a device for conveying a film web, which is used, for example, in the production of medicament packages, in particular blisters.
  • a device for conveying a film web with a housing, a plurality of rollers, which are rotatably arranged on the housing, and a roller receptacle on which a film web roll for unrolling the film web is arranged.
  • a device for conveying a film web with a housing, a plurality of rollers, which are rotatably arranged on the housing, and a roller receptacle on which a film web roll for unrolling the film web is arranged.
  • a device for processing a running film web which comprises a web guiding device with a pivotable about a pivot axis of the rotary frame on which two control rollers are pivotally supported, around which the film web runs. At each of the control rollers, the film web is deflected by 90 °. The entire rotating frame is held rotatable by means of a servomotor. The regulation takes place on the basis of a camera sensor, which determines the position of the web edge.
  • the disadvantage of this is, inter alia, that the integration of the web guiding device in the entire processing of the film web, for example in a packaging line, consumed by the additional components of the web guiding device to be prepared and maintained, space and resources and thus increases the manufacturing cost.
  • the device according to the invention for conveying a film web has a housing, a plurality of rollers, which are rotatably mounted at one end perpendicular to the web running direction on the housing, and a roller receptacle for receiving a film web roll, the roller receptacle rotatably mounted at one end perpendicular to the web running direction is arranged on the housing.
  • the device has a sensor which detects the position of the film web transversely to the direction of travel and transmits the detected value to a control device which is adapted to effect a displacement of the roller receptacle in the axial direction in response to the value detected and transmitted by the sensor ,
  • This provides a particularly simple construction of a web guiding control with exact film web control, which prevents a lateral offset of the film web and is applied to additional installation space, e.g. dispensed in a packaging line.
  • the device comprises in each case between two rollers at least one transfer roller which is rotatably mounted perpendicular to the web running direction and which is movable in synchronism with the roller receiving in the axial direction and substantially perpendicular to the plane spanned by the roller rollers web plane.
  • the running of the film web on the transfer and drive rollers is usually used to control the film tension after rolling the film web of the roll holder. Due to the common axial displacement of the transfer roller (s) simultaneously with the roller receiving a triggered by the control device correction of the film web course can be transmitted more effectively, since the axial displacement takes place at more than one position along the trajectory.
  • the device has a pivot arm, one end of which is pivotally mounted on the housing perpendicular to the web running direction.
  • the pivot arm is advantageously displaceable together with the roller mount in the axial direction.
  • At the other end of the pivot arm at least one transfer roller can be arranged rotatably mounted perpendicular to the web running direction, so that upon pivoting of the pivot arm, the at least one transfer roller between each two rollers is movable.
  • the axial displacement of the transfer roller (s) can be carried out simultaneously with the pivotal movement be, which can be dispensed with additional drives.
  • the device has an actuator for the axial displacement of the roller receptacle.
  • the actuator may for example be a servomotor with planetary gear.
  • other suitable drives are possible.
  • roller mount, the swivel arm and the actuator can be integrated into an assembly. This results in a particularly simple construction, can be moved in the role recording and swivel arm using a single drive in the axial direction.
  • the assembly is preferably guided via a carriage slidably on the housing. Furthermore, the actuator can cause the displacement of the module.
  • the senor is adapted to measure the deviation of an edge of the film web to a desired position.
  • the sensor is a camera with a resolution of ⁇ 0.1 mm.
  • Such a sensor is inexpensive and easy to install on the housing of the device without large space consumption.
  • Fig. 1 shows a schematic representation of a preferred embodiment of the device 1 according to the invention for conveying a film web 3 in working position.
  • the inventive device 1 as part of a Packing shown in the blister produced as drug packages and then filled with tablets.
  • a roller receptacle 9 On a housing 5, a roller receptacle 9 is arranged in a horizontal position, which is rotatably mounted at its one end.
  • a film web roll 11 On the roll holder 9, a film web roll 11 is mounted, from which a film web 3 rolls.
  • the film web 3 passes over rollers 7, 7 ', which are also mounted parallel to the roller holder 9 at its one end rotatably mounted on the housing 5.
  • the rollers 7, 7 ' are slightly longer in their dimension than the width of the film web 3, so that the film web 3 can extend completely over the rollers 7, 7'.
  • a pivot arm 17 is also mounted on the housing 5 in the plane of rotation of the roller mount 9.
  • a pivot arm 17 is also mounted on the housing 5 in the plane of rotation of the roller mount 9.
  • two parallel side arms are formed, at the ends of each a transfer roller 15 is rotatably mounted, wherein the transfer rollers 15 are parallel to the rollers 7, 7 'aligned and of the same type.
  • Both the roller holder 9 and the pivot arm 17 are fixed to the housing 5 via a mounting plate 25.
  • the mounting plate 25 and thus the roller holder 9 and the pivot arm 17 are relative to the housing 5 in the axial direction of the roller holder 9 movable.
  • the possible travel of the mounting plate 25 in the axial direction is about 20 mm in the illustrated embodiment.
  • a sensor 13 Fixed to the housing 5 is also a sensor 13, which is formed in the illustrated embodiment as a camera with a resolution of ⁇ 0.1 mm. As in Fig. 1 the measuring direction of the sensor 13 is shown obliquely upwards to the right, so that a film web course located in the measuring direction can be detected by the camera and the positioning of the edge of the film web 3 can be measured.
  • the film web 3 is unrolled from the film web roll 11 seated on the roll receptacle 9 and passes over the running rolls 7 and 7 ', wherein the film web 3 at the right above the running roller 7 and at the bottom right arranged roller 7' to each 90 ° is changed in its direction.
  • the measuring plane of the sensor 13 and the plane of the film web 3 intersect in the vertically downwardly running region between the upper right running roller 7 and the roller 7 '.
  • the pivot arm 17 is pivoted ⁇ by a certain angle downwards. In this position, the pivoting arm 17, the transfer rollers 15 are pivoted between the rollers 7 down through. It can be seen that the film web 3 is pressed by the pivoting of the two transfer rollers 15 between two rollers 7 down and thus deflected, resulting in a W-shaped course to the transfer or drive rollers 15 and 7 results. The film web 3 is firmly against the running surfaces of the transfer rollers 15 and the rollers 7 and is thereby maintained at tension. The treads have a suitable surface with sufficient friction to guide the film web. By corresponding pivoting or oscillation of the swivel arm 17 and thus the transfer rollers 15, it is therefore possible to perform the unwinding of the film web 3 of the film web roll 11 smoothly and without wrinkles.
  • Fig. 2 shows a perspective view of cut-out components of the embodiment Fig. 1 , It recognizes the role recording 9, the in Fig. 2 is shown without patch roll of film web, the mounting plate 25, on which the roller holder 9 is rotatably mounted, and an actuator 19, which is formed in the embodiment shown here by a servomotor.
  • the roller mount 9, the mounting plate 25 and the actuator 19 form the assembly 21, in the axial direction of the roller mount 9 with respect to the housing 5 (in Fig. 2 not shown) is movable.
  • the assembly 21 is slidably disposed in the axial direction of the roller mount 9 on a carriage 23 which is fixedly mounted on the housing 5.
  • the actuator 19, for example a servomotor is suitable for precisely displacing the assembly 21 in small steps with respect to the carriage 23.
  • the operation of the device according to the invention for conveying a film web will now be described with reference to FIG Fig. 1-2 described in detail and by way of example.
  • the in the Fig. 1-2 illustrated embodiment includes a (not shown) control device. It can be used all known types of suitable control devices, for example, based on electrical, hydraulic or pneumatic principle.
  • the film web 3 is clocked (about 5 cycles / min to about 50 cycles / min) unrolled over the transmission or running rollers shown.
  • the camera sensor 13 measures at each time the actual position of the edge of the film web 3 at the measuring position and gives them to the Control device eg as an electrical signal on.
  • the control device In the control device, the measured actual value is compared with a set target value for the position of the edge of the film web. In the event of a deviation between the actual and the desired value, the control device sends, for example, an electrical signal to the actuator 19, which moves the assembly 21 and thus the roller holder 9 and the pivot arm 17 in the axial direction of the roller holder 9 and thus perpendicular to the Folienabrollebene by a correction distance along the carriage 23 and thus of the housing 5. Due to the axial displacement of the roller holder 9, the film web roll 11 arranged thereon is likewise displaced in the axial direction, whereby the course of the film web edge is corrected accordingly.
  • the transfer rollers 15 are then no longer attached to the pivot arm, but on the housing 5 in parallel and analogous to the role recording, ie they are displaced in the axial direction.
  • the receptacles of the transfer rollers are perpendicular to the web running direction and perpendicular to its axis of rotation movable so that the already described above clamping effect of the film web is achieved. It is ensured that the axial correction movement of the roll holder and the transfer rollers takes place synchronously.
  • a device for conveying a film web has been created, which has a simple construction, dispenses with devices with high space requirements and thereby ensures an exact film web course.
