Definitions
- the sealing heads each have a heatable sealing contour plate on their end faces away from the carrier plate.
- the heater is designed as a semiconductor resistance heater and is firmly integrated in the sealing contour plate.
- the sealing contour plate is fixed on the sealing head by means of a cardan joint, which in the present case is designed as a ball, which is arranged between two plate-shaped elements of the sealing head.
- the ball allows the sealing contour plate to be tilted by small angles, but also allows the sealing contour plate to be rotated about an axis perpendicular to the contour.
- Sealing heads and carrier plate form a unit that is placed on the blister pack cover foil to carry out the sealing. In this process, the sealing heads come to rest after the sealing contour has been placed on the film, while the carrier plate is moved relative to the sealing head until the spring elements lying between the carrier plate and sealing heads generate the desired contact pressure of the sealing contours on the cover film.
- a disadvantage of the device according to the prior art has also proven to be its insufficient mechanical stability.
- the fixing of the sealing contour plate on the sealing head by means of a ball joint enables the sealing contour to be aligned parallel to the surface of the cover film, but it also allows the sealing contour plate to be rotated about an axis perpendicular to the contour.
- the latter possibility of movement is particularly Rem disadvantage, since it prevents an exact alignment of the sealing contour relative to the bulge in the lower plastic shell.
- the object of the invention is to provide a device for sealing bliester packs which avoids the disadvantages mentioned, enables simple and quick adjustment of the contact pressure of the sealing contour, and improves Sealing quality provides and has a low susceptibility to failure and accordingly low costs for repair and maintenance.
- An adjusting element is provided between the spring bearing plate and the sealing head, by means of which the distance of the spring bearing plate relative to the carrier plate can be changed, and / or
- the joint element is designed as a rubber bearing with two metal plates and a rubber layer in between, - the plates being vulcanized or glued, and / or
- the heatable sealing contour is made up of an independent contour plate and an independent heating plate
- the device according to the first proposal is based on sealing devices according to the prior art, which are equipped with guide bolts and spring elements which comprise the bolts and are arranged between the carrier plate and a spring bearing plate adjacent to the sealing head.
- the spring bearing plate in the device according to the invention is provided with bores so that it can move relative to and along the guide bolts and, in the same way as the sealing head, can carry out a linear displacement.
- the position of the spring bearing plate relative to the carrier plate determines the length of a spring element and thus its pretension.
- the spring bearing plate is designed so that its position is adjustable.
- Sealing head and the adjusting screw is arranged in the opposite edge region of the sealing head and the free end of one lever arm lies in the region of the sealing head axis.
- the adjusting screw comprises a cylindrical pin which can be displaced in the direction of its axis and a threaded pin with a hexagon socket head.
- the cylindrical pin is arranged between said lever and said threaded pin, while the threaded pin protrudes from the associated threaded bore and in the area thereof
- Head can be fixed with a lock nut.
- only a few manipulations are advantageously required to adjust the spring preload. They consist of loosening the lock nut, adjusting the setscrew by the required number of revolutions and then tightening the lock nut again.
- each bolt is provided with a groove with a dovetail flank, which are used to fix the rubber bearing on its neighboring elements.
- at least one threaded screw is provided in the sealing head and in the sealing contour carrier, which can be screwed against the mentioned flank.
- the quick-release system described also has a securing device against rotation of the rubber bearing.
- a hole is made in each of the metal plates outside the axis of the rubber bearing, in each of which a hole on the sealing head or sealing contour cylindrical center pin attached to the carrier engages.
- the constructive measures proposed in the context of the present invention for improving the sealing quality and for reducing the susceptibility to failure also include heating the sealing contour.
- the heatable sealing contour is constructed from an independent contour plate and an independent heating plate.
- the two plates are releasably connected to one another and releasably attached to the sealing contour carrier.
- This training leads to an essential improvement in maintenance and repair, since only the heating plate has to be replaced in the event of a defect in the heating or the thermostat.
- the entire unit consisting of sealing heads and carrier plate does not have to be removed, as in the case of sealing devices according to the prior art, but only the defective heating plate in a targeted manner. Since the contour plate and the heating plate are detachably connected to one another, the removal and installation of the two elements requires only little time and can be carried out in particular without removing further elements of the device.
- the heating plate is designed as a flat heater, preferably as a ceramic flat heater, or a heating plate with a heating cartridge. Because of their thermal conductivity, copper and / or aluminum are particularly preferred as the material for the heating plate and / or also for the flat heaters. Both versions have a very long service life, so that an exchange of this element is only necessary in comparatively large periods of time. Long downtimes of the packaging system and thus high production downtimes due to failed heating elements are practically excluded from the outset in the present device. Further constructive measures also serve the same goal of increasing the service life of the device as far as possible. These provide that the contour plate is made of hardened material or of a material resistant to aggressive substances, preferably stainless steel. This also increases the service life of the contour, the resistance to mechanical stress and the resistance to aggressive substances that may escape from the bulges of the lower shell when sealing.
- the present invention also provides a solution that deviates from the prior art.
- This is characterized in that the guide bolts mentioned are rigidly fixed in a base plate fastened to the carrier plate and the linear displacement of the sealing head relative to the base plate is effected by a displacement of the sealing head relative to the guide bolts.
- the sealing head accordingly has holes in which ball bushings are provided, which in turn run on the guide bolts. Moving the support point of the guide pin has a shorter lever arm compared to the prior art, so that the moments leading to tilting of the pin, which give rise to resistance to movement, are largely reduced.
- the spherical bushes make the Movement of the bolts, which allow a short working cycle to be realized.
- the proposed constructive measure achieves significantly better guidance of the sealing head. Tilting of the guide bolts in the guide bores cannot therefore occur a priori in the present device. The friction caused by the canting between the bolt and the bore with an undefined effect on the contact pressure of the sealing contour on the cover film of the blister pack is therefore excluded from the outset.
- the rigid fixing of the guide bolts on the base plate eliminates the lateral movements of the sealing head that are present in conventional designs of the linear guide, which are due to the play between the bore in the carrier plate and the guide bolt, and an exact alignment of the sealing contour relative to the bulge in the Prevent lower plastic shell.
- the equipment of the sealing head with ball bushings also largely eliminates the friction between the guide pin and sealing head in the event of a linear displacement of the sealing head, thereby also avoiding undefined effects on the contact pressure of the sealing contour.
- Contour plate, the heating plate or the rubber bearing are designed to be freely accessible, releasably connected to each other and can be replaced without removing other elements.
- a modular construction is provided according to a feature of the invention, according to the a sealing head with a contour plate, a heating plate, one or more insulating plates, a joint element, and a spring bearing plate, two guide bolts, two spring elements
- the sealing position is mounted on the base plate mentioned and thus form an independent unit, the sealing position. Furthermore, several of the sealing positions mentioned, e.g. four, attached to the same base plate, form a larger unit in this form, the row of seals. Several rows of seals, e.g. five, in turn, are detachably mounted on the carrier plate and together form the basic unit of the device, the sealing package.
- the electrical lines are fed via a multipole plug in the base plate, which engages in a complementary plug of the carrier plate.
- a clear assignment of the base plate to the carrier plate is advantageous in order to ensure that no incorrect or side-reversed installation can take place. This means that the exchange can also be carried out by re-trained assistants.
- the proposed structure provides an easy interchangeability
- the proposed structure also enables simple measurement and adjustment of the required temperatures and the force to be exerted by the sealing head on the pack to be sealed.
- a measuring device with measuring sensors for each sealing contour plate is placed on the sealing package, the actual values of the temperature and the pressing force are determined, and then the heating and the lever insertion Position individually adjusted to the respective target values for each sealing head.
- Figure 1 shows a schematic representation of a section through a sealing position
- Figure 1 shows the basic structure of a structural unit, which is performed under the above-mentioned designation sealing position.

- heating plate 2 insulating plate 3
- joint element 4 sealing head 5
- lever element 6 spring bearing plate 7
- guide pin 8 spring elements 9
- base plate 10 carrier plate 11.
- the guide bolts 8 are rigidly fixed in the base plate 10, the base plate in turn being detachably mounted on the support plate 11.
- the spring elements 9 are designed as coil springs, which comprise the bolts 8 and in the space between the base plate 0 and
- Spring bearing plate 7 are arranged. As can be seen from the figure, the spring bearing plate 7 has bores 12, which enable a displacement of the bearing plate 7 relative to the guide bolts 8. A displacement of the bearing plate 7 in the direction of the carrier plate 11 leads to a shortening of the springs 9 and consequently to an increase in the spring preload.
- the displacement of the bearing plate 7 can be caused by a one-armed lever element 6, which is articulated at point 13 on the sealing head 5.
- the lever is designed so that its first lever arm with his free end 14 against the spring bearing plate 7 and its second lever arm presses with its free end 15 against an adjusting screw, the position of which is indicated in the present illustration by the dash-dotted line 16. The position is selected so that the adjusting screw can be operated from the end face 17 of the sealing head 5.
- Ball sockets are shown under the reference symbol 18, which are arranged in bores of corresponding diameter of the sealing head 5. After the sealing head has been placed on the cover film 19 of the bliester pack 20, they enable the sealing head 5 to be displaced linearly on the guide bolt 8 in the direction of the carrier plate 11. The force generated by the prestressing of the spring elements 9 is transferred to the contour plate 1 and ensures a uniform contact pressure on the cover film 19.
- the present device is therefore equipped with a joint element 4, which consists of two metal plates 20, 20 'and a rubber layer 21 enclosed between the plates.
- This element enables the contour plate 1 to be tilted about the directions perpendicular to the axis 22 of the device, but does not permit rotation about the axis mentioned.
- the rubber bearing 4 thus ensures that the contour plate 1 is always aligned parallel to the surface of the cover sheet 19 and does not undergo any rotation about the axis 22.
- the rubber bearing 4 receives the sealing contour carrier 23 with the actual elements necessary for sealing. These include the contour plate 1 and the heating plate 2. Both components are designed as independent elements and releasably connected to one another. In order to prevent the outflow of heat from these two elements in the direction of the rubber bearing 4, a thermally insulating plate 3 is provided between the heating plate 2 and the joint element 4. As a result, the proposed device ensures simple and quick adjustment of the contact pressure, a high sealing quality, optimal accessibility to all components and low susceptibility to faults.
