Abstract

PURPOSE: To take out the refuse suitable for regeneration by limiting a seal on a surface area of a pack to be parted, and separately collecting the refuse of a molded film and that of a cover film after the parting of the pack. CONSTITUTION: A refuse collecting station 16 where two films are separately located, differently from a conventional method where only the refuse is collected together, is available by a special structure of a sealing tool. Accordingly, the waste films are not required to be taken up and instead, they are separately sent to a first reprocessing process comprising, e.g. a chipping process and/or a granulating process. A double film element comprising a molded film 11 and a cover film 12 and including the tablet products, is periodically passed through between two tool parts. A seal punch 22 comprises a raised work face 221, so that the punching waste part and a punching screen are not connected with each other among the materials, but instead they can be easily, rapidly and separately removed without fail.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention uses at least two foil or film webs of different materials drawn from a roll or L-reel in the form of a modeling base film and a cover film. The present invention relates to a method of making plister packs, or similar packs thereof, having a predetermined shape and a clearly defined volume, for receiving products to be packaged in a continuous operation or in a continuously timed operation. The present invention is an apparatus for sealing a pristar pack, which comprises a molding film that supports the product to be packaged, and a cover film that is bonded to the film when sealed by applying heat and pressure. , that is, regarding tools.

[Back of invention]

In order to use drugs in the form of tablets or capsules, prister packs have come into widespread use, and now it is rare to see tablets packaged in small tubes. However, for example, home, food, confectionery, business, office, etc.
Pristar packs are also used for packaging products in a very wide range of fields, such as the self-service field and the like.

Today, many tubes, bottles, tools, and workpieces, such as nail pullers, paper clips, spice containers, etc., are often found in the form of blisters. All these details are purely typical, as the development of this field is progressing and its applications are becoming more and more widespread.

In the traditional method used for packaging purposes today, a shaped film web is shaped to create a cavity to receive the product to be packaged, if necessary after heating or warming! -1 Then, fill it with the product to be packaged. A cover film web is fed to the shaped film containing the product to be packaged.

Both webs are joined together by a sealing action.

Separate the pack from the film web elements and collect the remaining film waste.

Conventional devices or tools used for this purpose consist of a pair of flat or roller-like tool sections, which, by relative movement to one another, receive the pack-forming film between them and carry out the sealing process. conduct. The first lower tool section has at least one recess for receiving at least one burr 7 star of the shaped film supporting the product to be packaged and is cooled, and the second upper tool section is cooled. In order to apply pressure, the pleated surface can be heated.

It is also known that the large amount of waste generated as defects during the manufacture of Pristar packs, especially in the pharmaceutical industry, is recycled, especially in view of the raw materials and energy sources and attempts are being made to reuse packaging materials. (DI-O8311
0254). As a result of the separation problems associated with the traditional combination of aluminum, i.e., PVC materials, to eliminate such problems, the combination of said materials, i.e., PVC and aluminum, is sent to a crusher to be granulated, where the resulting Aluminum and PVC granules are treated with plastic additives, especially raw plastic granules, to form new plastic products, especially in injection molding and extrusion processes. The materials generated do not need to be disposed of,
It is used in the construction industry as a filler in adhesives and sealing compounds, as well as in the production of chipboard and as an admixture in plastic mold structures for PU foam molds.

Thus, all of these relate to the use of mixed materials in mass-produced products, which may add meaning to the properties of the star)ff product, but which may be used without negatively impacting the final product. Not relevant where lower grade fillers and additives can be used. Thus, the cost and high value of the basic materials aluminum and plastics, such as PVC, are not taken into account. In fact, problems arise when packaging drugs in blister format, generally in the case of film nibs or foil webs made of different materials, such as having PCV as the shaped film material and aluminum as the cover film or foil. occurs. However, in many other fields, other plastics are used as the shaping film, paper material is used as the other film, and the whole is then joined together by a sealing action, i.e., adhesive, at the end of the packaging process. , it is also possible for these different materials to be joined. As a result, conventionally, one part of the packaging film web is
Between 0 and 20% of the amount is generated as interconnected waste pieces, i.e. punching screens, which are not sent to the recycling process and, unlike the recycling of defective waste in the pharmaceutical industry, these cannot be used. considered to be waste that cannot be
As a result, it had to be disposed of.

[Purpose of the invention]

The main object of the present invention is therefore to provide a conventional method and apparatus capable of satisfying environmental protection requirements with respect to the recycling of waste fresheners.

A particular object of the invention is to implement a blister packaging process which extracts waste suitable for recycling, but which allows expensive raw materials to be recovered individually.

Yet another object of the invention is to provide a method in which material costs are significantly saved and to provide a device suitable for the same.

In the aforementioned method, their purpose is to ensure that the sealing action is
This is achieved by being restricted to the surface area of the pack which is to be divided, and after the division of the pack, the waste materials of the building film and the cover film are collected separately from each other for recycling purposes. In the case of the above-mentioned device, these purposes are achieved according to the invention by one part of the packaging film during the sealing action.
This is achieved by ensuring that the boundary of at least one of the working surfaces of the two tool parts in contact with one another corresponds to the limit (boundary) of the surface of the pristine pack.

Thus, the sixth K solves those problems.

The method and device according to the invention makes it possible, during blister packaging, to obtain, with low technical outlay, one "product" of waste material, which product undergoes a recycling process for each individual product component. Therefore, this packaging process ensures that the waste of the film web during the production of such pristar packs is 10-20% and then it is recycled without any sorting process. It is very ecologically efficient1 and saves energy.This is an important step considering the increase in single blister packaging as mentioned above.
It even saves expensive raw materials. Furthermore, due to the fact that the cost of recycling the waste is substantially very low, it represents a significant cost saving. The construction of the tool according to the invention makes it possible to connect only the pack surface to be produced to the shaping film in a simple manner. The overall structure of such a tool is uncomplicated and can be very easily integrated into existing equipment, for example by milling or double loading, and by correspondingly reworking the existing tool. is also possible. Since the punching odor present in the equipment line, i.e. the separation station of the production line, i.e. the punching station, is structured in relation to the dimensions of the pack, it is the film 4! that runs through the pack! There is a precise separation along the working surface from the violet, so that between the individual packs the waste produced laterally is removed in successive waste elements and then further processed individually.

According to a further development of the nine methods according to the invention, in order to handle as carefully as possible packaging products that are particularly concerned with materials sensitive to heat and/or pressure, such as soft gelatin capsules, the sealing film is During operation, for sealing purposes, only the area of contact with the deep-drawn shaped film containing the product to be packaged is subjected to the necessary pressure and heat action.

In a particularly suitable arrangement of the sealing tool, the active surface is limited to the surface dimensions of the blister pack, if the blister pack has a flat cover film. The active surface of the second upper one-odor portion is: l− relative to its remaining surface portion;
It is raised. Incorporating this into an existing tooling part can be easily done by milling or elongating a surface that virtually corresponds to the film element in a conventional sealing plate. Only the pack surface to be produced remains as a working surface.

The heat and pressure supplied during the sealing process is particularly influential in the case of sensitive drugs, such as soft gelatin capsules, which are placed in shaped film blister 7'! :
In order to avoid any negative impact on the four items scheduled for packaging,
The working surface of the upper tool part is configured as a heat-free location corresponding to the number, size, and positioning of the depressions in the lower tool part.

Other objects of the invention will become apparent from the following detailed description and claims, and are illustrated in the accompanying drawings.
, the drawings schematically depict, by way of example, preferred embodiments of the invention and its principles, and further illustrate the same principles as the present invention, in order to indicate the most suitable application of these principles; Alternatively, other embodiments of the invention embodying the principles which are considered equivalent may be used by those skilled in the art without departing from the scope of the invention and its claims. Structurally, it can be modified by different people.

[Example] A blister packaging device whose principle is shown in a simplified form in FIG.
and the cover film 1 unraveled from the storage reel 121.
2 is arranged on a machine stand for making blister packs of medicines (tablets, capsules, etc.), that is, a base 1G, that is, one place for receiving tablets 3, that is, a blister 112 (FIG. 2). A modeling station 13 deep-draws the modeling film 11 to form a
2 and a separation station 15 for punching finished printer packs from the continuous film web;
- a waste part collection station 16 in which a separate collection reel is arranged: a waste part collection reel 182 of the cover film 12; Unlike previous methods in which only the waste materials were collected together, this waste collection station 16 with two films in their separate configurations has a combined sealing system according to FIGS. 2 and 3. This is possible due to a special structure. Naturally, there is no need to wind up the waste film; instead, said waste film is clearly sent separately to a first reprocessing step, which is constituted by, for example, a shredding step and/or a granulating step.

As shown in FIG. 2, the sealing station 2 forming the basic part of the sealing station 14 consists of a lower tool part 21 in the form of a counter-holding plate and an upper tool part 22 in the form of a sealing bunch. The two tool parts 21,22 are shown in their inactive position, ie in a position separated from each other. A double film element consisting of a shaping film 11 and a cover film 12, in which a blister 112 has already been formed, in which the product is arranged in the form of a tablet, is
periodic passes between the tool parts. In the illustrated position, the blister 112 is positioned above the recess 211 formed in the counter-holding plate 21 . The sealing process starts at this position, in which case the counter-holding plate 21
rises in the direction of arrow A, so that the blister 112 is received in the recess 211 and its counter-holding plate 21 is not heated and, if necessary, is properly cooled, first of all the underside of the building film 11 comes into contact with. The sealing punch 22 heated to the required temperature is usually fixed, but it can also be configured to move downward in the direction of arrow B. As a result of this relative movement, the surface of the modeling film 11 is pressed against the cover film 12. Since the lower side of the cover film 12 is provided with an adhesive layer necessary for bonding, the pressure generated between the counter-holding plate 21 and the seal bunch 22 and the heat transmitted by the punch 22 cause the shaping film 11 to be bonded. Contact with the surface occurs.

As seen from the bottom view of FIG. 3 together with the side view of FIG. It is obvious, as a result of which it can be ensured that the punching discard part and the punching screen do not have any connection between the materials, instead ensuring that they can be easily and quickly removed separately. In the purely exemplary method shown, the pack consists of three deep-drawn tablet blisters. The working surface is created by milling the sealing plate relative to the remaining part of the sealing plate. However, other suitable manufacturing methods can also be used to create this working surface.

The punching tool of the punching station 15 is equipped in a corresponding manner so that it is possible to punch out the puck corresponding to the working surface in order to remove it from the device 1 and to remove one waste film of the building film 11 or the cover film 12. The strips are fed according to the ladder-like grid shown in FIG. In other words, the integral surface of the cool punch 22 forms a recess 222 with respect to the working surface 221, which in order to improve the sealing pressure also has a pleat system 223 (which is well known per se). is shown only in the upper left part, but is actually formed over the entire working surface), and also has an unheated position 224 corresponding to the recess 211 of the lower tool part 21. There is. If the tool has a plate-like structure (as shown), the pleat system will form small pyramidal or trapezoidal ridges so that the film is not flat.
Even in the presence of protrusions, the sealing pressure is applied evenly, resulting in a defect-free pack. However, if roller or drum tools are used, their surfaces are provided with a ridge device that intersects to obtain an even pressure condition.

The illustrated plate-shaped sealing tool and the correspondingly designed punching tool enable a continuous time-measured production process. However, if one wishes to have an untimed continuous work flow, one can adopt the aforementioned tool structure in the form of rollers or drums, and then, for timed operations, set the tools relative to each other. Precise control over position.

The effect achieved by the invention is that a separate film waste product with a well-defined consistency is obtained, which can be easily and quickly transferred to a dedicated recycling process tailored to the specific individual material elements. This results in a very pure, high-grade recycled product. At the same time, the cost of manufacturing a pleat system that is limited to specific pack dimensions can be reduced, at least in respect of the marginal portions. In view of the large number of different pack sizes and the need to keep the proper tools in service, these tools, along with them, are very important to the assembly and manufacturing costs of the device. Furthermore, especially since the present invention does not require any disposal of the significant amount of film waste that is obtained especially in the pharmaceutical packaging industry, the present invention makes a significant contribution to the ecosystem, and the packaging technology make the design environmentally friendly.

The invention is of course not limited to this particular field of packaging technology, since films, foils or layers of different types of materials have to be processed, which combine to form waste products. connection, and is successfully used even where its separate disposition would create problems. This applies, for example, to the dairy industry, especially in filling equipment where the plastic for filling is supplied as a continuous web which is heated and probed like a large adhesive unit by a shaping punch or vacuum. It is also used for the function of filling deep-drawn plastic containers, after which the unit is filled and drawn from a storage reel at the sealing station, unlike in the case of individual tap fillings, which are often used for continuous aluminum filling. Sealing is done with foil. In the past, methods have been used in which the punchings obtained in the punching screens of individual chips have to be shredded and disposed of in this way. The invention also allows the plastic material and the cover (aluminum) foil to be removed separately for recycling purposes to save raw materials.
