Definitions
- the present invention is concerned with the adjustment of foils to each other and the snug assembly of the films into a film composite.
- the present invention relates to a method for producing a composite film comprising at least two films which are arranged in a defined manner in the film composite to each other, and a system for producing such a composite film.
- Foil composite systems appear in daily life in many ways.
- An example of a film composite is a blister pack, often referred to as a blister for short.
- Blister packs are preferred packages for drug portions such as tablets and capsules.
- the tablets or capsules are in an arrangement of individual wells (bubbles) in a plastic or aluminum foil.
- the bubbles are usually sealed by an aluminum foil.
- the drug portions can be removed individually by pressing in the blisters and pushing the tablets through the aluminum foil. In the closed bubbles, the tablets are protected against dirt and humidity
- Blister packs, devices for their manufacture, and devices for packaging drug portions in blister packs have been well described in the prior art (see, for example, US4384649A, GB2184086A, EP2272763A1, EP0849055A1, EP0257990A2, EP0210823A1, DE3803979A1, CN203003955U).
- bubbles are introduced into a first film (bubble film, blister film), in a second step products (eg tablets) are filled into the bubbles and in a third step the bubbles are filled with a second film (sealing film ) locked.
- the blister film and the sealing film are usually in roll form or in sheet form.
- the punching of individual blister packs from the film composite is usually in roll form or in sheet form.
- the published patent application EP0210823A1 shows by way of example a device with which a bubble film and a sealing film in the form of rolled goods can be joined together.
- the sealing film is usually printed.
- the printing of the sealing film can be done before merging with the blister film or afterwards.
- the printing of the sealing film takes place before merging of blister foil and sealing foil.
- blister packs in which the information printed on the sealing film must have a defined orientation with respect to the blisters.
- some medicament blister packs are printed so that directly above the blisters on the sealer foil the days of the week are printed in abbreviated form (Mon, Tue, Wed, Thu, Fri, Sat, Sun) so that the patient knows which tablet to take on which day must push out the blister.
- abbreviated form Mon, Tue, Wed, Thu, Fri, Sat, Sun
- blister film and printed sealing film must be placed one above the other in a corresponding manner before they are joined together.
- This orientation of the sealing film with respect to the blister film is done manually and is time consuming.
- EP2860119A1 describes a device for joining together at least a part of the cover film with a part of the base film to form a film composite (also called a sealing device) with built-in detection devices.
- sealing station and cutting station - detection devices are positioned in the form of a camera or a print mark sensor in the sealing device, which determines the position of a mark on the bottom and / or top film of the package before each processing step and passes it on to a control unit.
- the second lower foil marking device is used in front of the sealing station for the exact positioning of a second forming station, so that the lid can be brought together in the sealing station exactly with the associated trough whose position has been detected via the marking.
- the solution shown leads to an improvement in the appearance of the packaging by online control of the feed steps, control of a stretching device and / or positioning of motor-adjustable forming stations and cutting station. No detection device is used to control the finished package.
- This solution requires complex equipment of the sealing device with corresponding detection devices in front of each station; the quality of the finished sealed product is not determined.
- a first object is a method for producing a film composite comprising at least one base film and a cover film, wherein the cover film has elements which are to have a defined desired position with respect to elements of the base film,
- the position of the cover film elements with respect to the base film elements are determined by means of an optical recording device, so that an actual position results, the actual position is compared with the desired position in order to determine a deviation of the actual position from the desired position, based on the deviation of the actual position from the desired position, machine parameters are determined which transmits machine parameters to the device be, and the device takes over the machine parameters and thus the cover sheet and the base film adjusted to each other, that corresponds to the position of the cover film elements with respect to the base film elements of the desired position in the further joining of cover film and base film.
- the actual position is determined in the form of an image of at least one region of the film composite produced by the optical recording device.
- the desired position is deposited in the form of an image of at least one region of the film composite produced and the actual position is an image of at least the region of the film composite produced, which is deposited to define the desired position.
- a further subject matter of the present invention is a system comprising a cover film comprising cover film elements, a base film comprising base film elements, a device for joining at least part of the cover film with a part of the base film into a film composite in such a way that the cover film elements in the Foil composite in relation to the base film elements in a defined desired position, and
- an optical recording device for optically detecting the actual position of the cover film elements in relation to the position of the base film elements in the film composite, wherein at least the region of the film composite produced, which is deposited to define the desired position, can be detected
- a computing unit for determining the deviation between actual position and desired position
- an arithmetic unit for determining machine parameters on the basis of the deviation between actual position and desired position, wherein the machine parameters specify how the device has to align the cover film and the base film to each other so that the actual position corresponds to the desired position.
- the desired position is stored in a data memory.
- This data memory may be an element of the optical recording device and / or an element of the arithmetic unit for determining the deviation between the actual position and the desired position; the data memory can be called up by the arithmetic unit to determine the deviation between the actual position and the desired position via communication elements.
- the device for joining together at least a part of the cover film with a part of the base film to form a film composite the optical recording device for optically detecting the actual position of the cover film elements with respect to the position of the base film elements in the film composite, an arithmetic unit for determining the deviation between actual Position and target position, a computing unit for the determination of machine parameters on the basis of the deviation between Actual position and target position and the database for storing the target image are called individually or together system component.
- the optical recording device for optically detecting the actual position of the cover film elements with respect to the position of the base film elements in the film composite does not have to be in the device for joining at least part of the cover film to a part the base film to a film composite firmly mounted and accurately positioned.
- the definition of the desired position is made particularly simple: take a target image, store it in the data memory and the system is ready for use.
- the optical recording device for optically detecting the actual position of the cover film elements with respect to the position of the base film elements in the film composite is designed as a mobile device.
- the arithmetic unit for determining the deviation between the actual position and desired position and possibly the arithmetic unit for determining machine parameters based on the deviation between actual position and desired position can be integrated.
- the mobile device may be connected to one or more of the further system components via communication systems for the transfer of information between the system components.
- the mobile device is applicable to any device for joining at least a part of the cover film with a part of the base film to a film composite (sealing device). If another packaging is to be made in this sealing device, then an image of the desired position of the new composite film is deposited in the database, which is defined and called up as the target position for the arithmetic unit for determining the deviation between the actual position and the desired position ,
- a cover film and a base film are first (largely) joined together without regard to the position of the cover film elements in relation to the position of the base film elements to form a film composite. Then, the actual position of the cover film elements in relation to the position of the base film elements is determined optically. From the actual position and the desired position, the deviation of the actual position is calculated to the desired position. Finally, machine parameters are calculated from the deviation and transmitted to the device, by means of which the device can adjust the cover film and the base film to one another in such a way that the cover film elements are in spatially defined relation to the base film elements in a further joining of base and cover film to a film composite ,
- a film is understood to mean a flexible and flat structure.
- Flat means that the film has a dimension in a spatial direction (the so-called height or thickness) which is substantially smaller (at least a factor of 10, preferably at least a factor of 50) than the dimensions in the other spatial directions (length, width ).
- Flexible means that the film can be bent to some degree without it irreversible damage.
- a film may be rolled up onto a cylindrical body and unrolled again without leaving significant marks on the film.
- Typical examples of films are the household-known cling films or aluminum foils. Also known from the earlier analog cameras photographic film is an example of a film.
- the cover film and the base film are films.
- the term foil is not to be understood to mean that it is a uniform material.
- a film in the sense of the present invention can, for example, also be a film composite. In a film composite, several (at least two) films are combined to form a body. Coated films are also films in the sense of the present invention. For example, many packaging films are coated with aluminum to increase the barrier property of the film to air and / or moisture or to reduce light transmission.
- bubbles / depressions for receiving objects may be introduced into the cover film and / or the base film.
- the cover sheet and / or the base film may be printed, and have punches, notches and perforations.
- the cover film and / or the base film usually consist at least proportionally of a polymer.
- Cover film and / or base film can be in rolled up form (as rolled goods) or in the form of sheets (as sheet goods). Preferably, they are available as rolled goods.
- coversheet and base sheet are components for producing a drug package blister pack (e.g., tablets or capsules).
- a drug package blister pack e.g., tablets or capsules.
- the base film may be a blister film. This means that in the film recesses for receiving objects (drug portions) are introduced.
- the cover film may then be the sealing film for closing the depressions of the blister film. It is also conceivable, however, that the base film is the sealing film of a blister pack, while the cover film represents the blister film.
- the shaping of the blister contour is usually done by thermoforming technology.
- the blister foil usually consists of polyvinyl chloride (PVC).
- the blister film usually has a thickness in the range of 0.25 mm to 1.25 mm.
- PVDC polyvinylidene chloride
- the sealing film is preferably made of aluminum or an aluminum-coated polymer. It is preferably printed with characters.
- the base film and the cover film have elements (the cover film elements and base film elements referred to here) which are to be produced in the film Foil composite should take a defined spatial orientation to each other.
- the cover film elements and / or base film elements lie in a recurring, defined distance from one another.
- the base film elements and the cover film elements may, for example, be external delimitations of the film (for example corners or edges), markings, characters, punches, indentations or else the blisters of a blister film.
- the elements of the base film do not have to match the elements of the cover film.
- the elements do not have to be integral parts of the film, but they can be applied to or on or in the film. It is crucial that the position of the elements on, on or in the respective film is defined and optically detectable or ascertainable.
- the base sheet elements are the blisters of a blister sheet and the cover sheet elements are characters (e.g., days of the week in abbreviated form).
- the cover film elements and the base film elements should be positioned relative to one another in a defined manner.
- the base film elements are the blisters of a blister film and the cover film elements are characters, then "positioned in a defined manner" means, for example, that the characters are centered over the blisters.
- the defined position of the cover film elements with respect to the base film elements is also referred to as the desired position.
- At least a part of the cover film is placed on a part of the base film.
- cover sheet is in sheet form and the base sheet is rolled, the complete cover sheet may be laid on a portion of the base sheet. In this application, the desired position can initially be largely ignored.
- the folding of the films is done by means of a device.
- a device Such devices are described inter alia in the prior art described in the introduction. Usually it is the device that also takes over the joining of cover and base film. Typically, these are lamination devices such as described in the book by Thomas Dunn, Manufacturing Flexible Packaging, 1st Edition, Elsevier 2014, ISBN: 978-0323-26436-5 ("Dunn_2015").
- the cover film and the base film are positioned relative to one another in the device in such a way that, when the films are joined, the cover film elements and base film elements are present at least approximately in the desired positions relative to one another.
- the cover film elements and base film elements are present at least approximately in the desired positions relative to one another.
- the cover film can be moved to each other in at least one spatial direction.
- the cover film can be displaced relative to the base film (or vice versa) in the running direction of the rolling film and / or perpendicular thereto. Manual adjustment of cover film over base film (or vice versa) is time consuming.
- Cover film and base film are thus fixed in the device, so that at least a part of the cover film can be placed on a part of the base film and the folded parts are mechanically joined together.
- the assembly of the films is usually done by a lamination process, optionally using an adhesive. Whether an adhesive is used depends primarily on the present materials of the films to be joined. There are materials that can be combined at elevated temperature and under pressure. Other materials require an adhesive between the pieces of film to be assembled. After assembly, cover film and base film form a coherent body. Usually, the assembled films can no longer be separated from each other without destroying each other.
- cover film elements lie in a measurable position with respect to the base film elements.
- This measurable situation is the actual situation.
- This actual position is determined in a next step of the method according to the invention with the aid of an optical recording device.
- the optical pickup device is usually a camera that has an image sensor that is designed to receive two-dimensional images of light by electrical means.
- a semiconductor-based image sensor is used that can pick up light in the visible range to mid-infrared. Examples of such semiconductor-based image sensors are CCD sensors or CMOS sensors.
- Decisive for the type of optical recording device used are the type of elements to be detected cover sheet and / or base film and the wavelength of the light used for imaging.
- the produced composite material is irradiated with electromagnetic radiation, which can be detected by the image sensor, and the radiation reflected and / or scattered by the film composite is captured by the image sensor.
- a corresponding camera optics (comprising lenses and / or diaphragms) ensures that an image of at least one region of the film composite produced is imaged on the image sensor.
- cover film elements and / or the base film elements themselves are excited to emit electromagnetic radiation, wherein the radiation emitted by the elements can then be used for imaging on an image sensor. It is conceivable, for example, for the cover film elements and / or the base film elements to carry a fluorescent dye which, for example, can be excited with ultraviolet light to emit radiation in the visible range.
- the image of the cover film elements and / or the base film elements on the image sensor must have a sufficiently high resolution, which makes it possible to bring the actual position within the required fault tolerance with the desired position in accordance. This point will be explained in more detail below.
- a punched-out packaging is optically detected.
- the figure shows the position of the cover film elements relative to the base film elements (or vice versa).
- the cover film elements and the base film elements need not necessarily be visible even in the figure; it is sufficient to recognize elements that allow a unique location of the coversheet elements relative to the base sheet elements. This will be explained below by way of example.
- the base film is a blister film and the cover film is a sealing film for closing the recesses of the blister film.
- the aim is to produce blisters in which an imprint on the sealing film lies in a defined position in relation to a depression in the blister film.
- the imprint and depressions are on opposite sides of the blister.
- the two sides of the blister can not be captured simultaneously in one image.
- the position of the recesses can be clearly determined by the edges of the blister (see the comments below).
- the edges of the blister (or part of it) can easily be captured together with the imprint on the sealing film in a single image.
- the position of the cover film elements (imprint on sealing film) in relation to the position of the base film elements (depressions in the blister film) is not recorded in the figure, but the position of the cover film elements (imprint on sealing film) in relation to the position of elements (edges of the blister) , which allows an unambiguous position determination of the base film elements (depressions in the blister film).
- the optical recording device for optically detecting the actual position of the cover film elements with respect to the position of the base film elements in the film composite typically has an element for receiving and positioning the blister (film composite or part thereof). to the optical recording device.
- the edge of the blister can be determined and used as a positioned element of the base film in the comparing step of the actual position with the desired position.
- the use of the edge as the base film element is particularly advantageous if the base and cover films are opaque.
- the recesses for receiving objects are introduced into the blister foil.
- objects eg medicament portions
- thermoforming the blister sheet is unwound from the roll and passed through a preheat station.
- the film is heated so that they becomes soft and flexible.
- the heated sheet then passes into a forming station where, under the application of high pressure (4 to 8 bar), the film is pressed into a mold which results in the formation of the depressions in the film.
- the film is cooled sufficiently to retain the shape imposed by the die.
- the objects can be introduced and it can be applied to the sealing film.
- individual blisters are then punched out of the film composite.
- the blisters remain in the mold during the entire process until the individual blisters are punched out, then they can not slip during the entire process and their position in relation to the edges of the blister depends only on where the punch attaches.
- the punching position is usually clearly defined by the punching device.
- the corners and edges of the punched blister have a unique position with respect to the recesses (and vice versa), so that when knowing one position, the other can be calculated.
- the method according to the invention comprises the step of determining the actual position. As described, an optical image of a part of the film composite produced on an image sensor is effected for this purpose.
- the position of cover film elements in relation to the position of base film elements can then be measured or deduced on the image recorded by the image sensor.
- the measurement or derivation preferably takes place automatically with the aid of image recognition methods.
- image recognition methods are extensively described in the literature. In the following, only a small selection is made: J.P. Marques de sense, Pattern Recogition, Springer 200, ISBN 3-540-42297-8; V. A. Kovalevsky, Image Pattern Recognition, Springer 1980, ISBN 13: 978-1-4612-6035-6; Ernest L. Hall, Computer Image Processing and Recognition, Academic Press 1979, ISBN 0-12- 318850-4; Image Recognition and Classification, edited by Bahram Javidi, Marcel Dekker, Inc., 2002, ISBN: 0-8247-0783-4.
- the deviation is still zero from the point of view of the image recognition system.
- the actual position before moving is actually different from the actual hiding before shifting. This means first that the actual situation in practice can not be absolute but that it is an area. Only then, when the actual actual position is outside this range, in practice, a change in the actual position can be detected. Since the actual position can not be determined exactly, it makes no sense to demand an exact (absolute) target position, the absolute compliance can not be detected anyway.
- the target position is more an indication of the kind: the position of the center of the mark x and the position of the center of the mark ⁇ when viewed vertically (to avoid a parallax error) at the same place with a deviation of 0.01 mm in the direction of the films and with a deviation of 0.01 mm are perpendicular to the direction of the films.
- the actual position is more an indication of the kind: the position of the center of the mark x is identical with that of the position of the center of the mark ⁇ with an accuracy of 0.01 mm in the direction of the films and with accuracy of 0.01 mm perpendicular to the running direction of the films.
- the image sensor must be adapted accordingly to the required tolerance of the target position. If an accuracy of 0.01 mm is required, the image sensor must have a correspondingly high resolution in order to be able to capture this accuracy when detecting the actual position.
- the deviation can be determined as soon as the positions of cover film elements in relation to base film elements are determined.
- All these calculations are preferably carried out automatically by one or more corresponding computing units.
- This may be a single arithmetic unit, which may be part of the optical recording device; but they can also be different arithmetic units, which are connected to one another via communication channels in order to transmit determined and calculated data.
- the optical recording device in addition to the automatic recognition of the positions of cover film elements and base film elements, the optical recording device also undertakes the calculation of the deviation of the actual position from the desired position and the calculation of the corresponding machine parameters.
- the machine parameters are then transmitted to the device for joining cover sheet and base film. In the simplest case, this transmission is made by a human (user). After the cradle has calculated the machine parameters, they are displayed and / or left on a screen to save on a data memory. The user then transmits the displayed machine parameters to the device for assembling cover film and base film, for example by manually entering them via a suitable input device (eg keyboard), or connecting the data memory to the device and transmitting the machine parameters from the data carrier to the device corresponding control commands starts.
- a suitable input device eg keyboard
- the data transmission can e.g. wireless via bluetooth or wired e.g. via a network cable.
- the device and the optical pickup device may be separate units that are not physically connected to each other. It is conceivable that they are operated in different rooms. Such a division of the functions of the system according to the invention into separate units can e.g. be advantageous if there are several devices for joining films, all of which rely on a corresponding optical pickup device.
- the optical pick-up device is then operated as a "stand-alone device.” It is also conceivable that the optical pick-up device is a mobile device that can be transported to a device for assembling foils if required.
- the optical pickup device is an integral part of the device for assembling foils.
- the image sensor is a component for the overall process: aligning the films, joining together, determining the actual position and the deviation of the actual position from the desired position, determining the machine parameters, correcting the orientation of the films, further joining the films, the Actual position corresponds to the desired position.
- the present invention is preferably used for the production of blister packs.
- This preferred embodiment will be explained in more detail below, but without limiting the invention to this embodiment.
- the base film is a film for producing a blister film and the cover film is a sealing film for closing the blisters of the blister film.
- the foil for producing the blister foil and the sealing foil are on rolls.
- the sealing film is already printed. It is important to align the printed image on the sealing film with respect to the position of the bubbles in the finished blister pack in a defined manner.
- the device for joining the cover and the base film allows continuous introduction of the bubbles in the base film by means of thermoforming, filling the bubbles with drug portions, laminating the sealing film on the base film and punching out blister packs from the laminated film composite.
- the base film thus first passes through a station for introducing the cavities into the base film. Subsequently, the cavities are filled with drug portions. Subsequently, the sealing film is applied.
- the application of the sealing film is largely without regard to the position of the printed image with respect to the position of the bubbles. If a first piece of the film composite is made, it is very likely that the actual position does not correspond to the desired position.
- the continuous process is stopped.
- the stopping can be done either automatically (machine-controlled) or by a user.
- a blister pack is removed and placed in the optical receptacle.
- the optical pickup device generates an image of at least a portion of the blister pack on an image sensor. From the image sensor, the digitized image is transferred to a working memory of a computing unit.
- a computer program for image processing, analysis and recognition optionally performs preprocessing of the digitized image (noise reduction, binarization, edge filtering or the like) and analyzes the digitized and preprocessed image to determine the position of the printed image (or parts thereof) relative to the image Determine edges of the blister pack.
- the computer program If the computer program has recognized the edges of the blister pack and characteristics of the printed image, it calculates the actual position of the printed image in relation to the position of the bubbles (which in turn results from the position of the edges).
- the desired position is stored in a data memory in the optical recording device.
- a computer program reads the desired position from the data memory and performs a comparison between the actual position and the desired position. It calculates the deviation.
- the machine parameters are displayed on a screen of the optical pickup.
- the machine parameters can be transferred to the device for assembling the films.
- the device for assembling the films adopts the machine parameters and re-aligns the cover film with respect to the base film (or vice versa), so that when starting the device and thus in the continuation of the continuous process, the actual position corresponds to the desired position.
