    专利说明:

    The invention relates to a device with a shaping apparatus for manufacturing sheet pieces from sheet material supplied. It also relates to a process for the manufacture of these sheet pieces.
    Such devices for the manufacture of preformed sheet, for example for molding packages or covers for computer keyboards or similar objects, are known and have been proven in practice. The sheet pieces thus manufactured are, however, very simple in nature and have no other functional characteristic beyond their property as packaging or covering. In addition, these sheet pieces are in themselves most often unattractive and therefore have, especially when used as a sales package, no properties or only minimal advertising properties.
    Therefore, the problem is in particular to provide a device and a method of the type mentioned at the beginning with which it is possible to manufacture sheet parts which have additional functional characteristics as well as an attractive external appearance.
    The solution according to the invention to this problem consists in that at least one injection station for at least locally injecting synthetic material onto the sheet member is disposed downstream of the forming apparatus.
    Functional properties may be related to this injection-applied synthetic material and the appearance of the sheet piece may be further improved, which may have a sales promoting effect.
    The synthetic material can in this case be applied or injection-molded on the surface of the sheet piece, and can also optionally be injected into depressions or cavities of the sheet piece.
    One embodiment provides that the shaping apparatus is configured for forming open sheet pieces. Such sheet preforms may be parts of a package, for example a blister package, or functional parts, for example computer keyboard covers.
    One embodiment provides that the device has a blister packaging machine. With this, the blistered preforms can be packed with an object, for example a toothbrush, and the open side can then be closed with a lid.
    The injection application of synthetic material can be performed on the preformed sheet after completion thereof or can be performed on the packaging unit available after the blister packaging machine.
    In order to maintain the sheet preform during the injection process and to define the injection region, it is appropriate for the injection station to have a mold for partially or wholly receiving a sheet piece or sheet preform.
    In order to be able to apply different injection moldings, if necessary, on several sides or in several places of the sheet part, it is advantageous if a plurality of injection stations are provided for applying synthetic material to the sheet-piece at these locations. on these sides and / or on the cover layer applied to the sheet piece, and / or that the multiple injection stations are configured to apply different color synthetic material and / or different synthetic materials.
    When injection-applied to a cover layer, for example the cardboard back wall of a toothbrush package, low-melting synthetic material is preferably used to prevent damage or tampering. due to heat such as discolouration of the cover layer.
    Said at least one injection station may have several injection nozzles, preferably for the injection of different synthetic materials, in particular of different colors. A variable application on molded parts with an injection station which has a cheap and space-saving structure is thus possible.
    Said at least one injection station is preferably configured to apply by injection of the synthetic material on the sheet piece in a thickness of the order of less than a tenth to a few tenths of a millimeter. As a result, only a small amount of material is required for the applications, and the injection station itself can also be produced at a favorable price and in a space-saving manner. In addition, it is necessary for the application of the synthetic material that very little time, so that the rate of the entire manufacturing device is not influenced adversely, so is virtually not slowed down, by the process or processes of injection, which has the consequence of being advantageous in terms of cost for the production process.
    It is appropriate for the at least one injection station to be designed to inject or to injection mold an adjustable foot, suspension flanges or similar functional elements of injection-applied synthetic material. In particular, blister packs can thus be provided with an adjustable foot so that they can be erected or be configured by injection molding of a suspension flange so as to be able to be suspended in order to be able to present them in such a way as to favor the sale. Other functional elements are also conceivable such as, for example, projections to better grip the sheet piece or closure elements to be able to close a package that has been opened once. Supporting or stopping elements inside a blister, to hold the object to be wrapped, for example a toothbrush, in a defined position are also possible.
    In particular, when the injection moldings serve as a bearing surface for the sheet piece, it is advantageous that the synthetic material to be injected is of the rubbery type. A piece of sheet or preformed shaped sheet is therefore well insured against a lateral movement. In order for the sheet piece, particularly when it is a blister pack, to hold better in the hand, rubber-like injection moldings can be advantageous.
    For quick and easy injection application for additional elements on the injection-processed sheet part, an injection station may be disposed above or below the injection-processed sheet part and the injection nozzle. injection station injection can be directed downward or upward, and directed towards the sheet piece.
    To treat by injection, at the same time and therefore by saving time, sheet parts or closed blister packs, at least one injection station can be placed both below and above the sheet injection-treating and the injection nozzle of the injection station can be directed upwards or downwards and directed towards the sheet piece.
    In addition or alternatively, injection stations can of course be arranged on the side.
    According to a configuration, said at least one injection station may be designed to inject symbol type marks by injection. These marks can in particular be arrows to draw attention to important details of the package. But other marks such as circles, crosses, etc. are also possible. In addition, initials, company emblems or distinctive marks for a packaged product may also be provided as symbol type marks.
    Another embodiment provides that said at least one injection station is adapted to inject plastic material as a fastener for additional elements applied to the sheet member. For example, in the case of transparent blister packaging for toothbrushes, an optical magnification element, by which the roundness of the pile filaments can best be seen as a quality characteristic, can be fixed in the region of the brush head by injections or be formed by the same injection. It is also conceivable to remove the material of the bristles on the outside of the blister package and to fix it with the injection-molded synthetic material so that the customer can feel the material of the hairs before the purchase so as to be able to take better a purchase decision.
    A sales promoting effect can also be obtained when the at least one injection station is designed to inject synthetic material corresponding to the material, and / or the shape and / or color of an object packaged in the sheet piece. It is thus possible to reproduce the nature of the handle of a toothbrush to provide the customer with a tactile test beforehand and give him an idea of the characteristics of the handle of the toothbrush, without the packaging being opened for this purpose , which is not possible if only for hygienic reasons.
    Touch streaks are also possible to give the customer the sensation of a tongue scraper
    In particular, when it comes to hygienic articles, for example toothbrushes or tongue scrapers, it is advantageous that said at least one injection station is designed to apply synthetic material used as a tamper-resistant closure. a blister pack. When opening the package, such an injection molding is damaged or ripped so that it is clearly visible that the package has already been opened previously, even for example when the cover layer of the blister package has been glued with the blister sheet.
    Another improvement idea of the invention provides that said at least one injection station is designed to apply synthetic material for reinforcing material. This may for example be used to form film hinges, in that in the region of the hinged joint provided, the sheet material is weakened or perforated or entirely cut and This region is then covered in whole or in part with synthetic material. This increases the elasticity of the hinge joint and extends its life.
    When elastic synthetic material is used, it is also possible to provide the at least one injection station for applying synthetic material as a lining particularly along the outer periphery of the sheet piece. The sheet piece with the synthetic material running around its periphery can then be inserted into an opening of a container or similar object, for example as a closure cap.
    It is also conceivable that said at least one injection station is designed to apply synthetic material on the surface to material recesses of the sheet piece. In a piece of sheet, is first stamped for this purpose a recess for example round which is covered with synthetic material in particular colored. The sheet piece can then serve as a cover for a functional element, a push-button electric switch for example being disposed below the recess coated with colored synthetic material. This can also be done, for example, for emergency switch systems to clearly distinguish the emergency switch and make it easy to maneuver. It is also possible to envisage actuating surfaces which allow actuation of individual keys, for example of a remote control packaged in a blister, for testing purposes.
    The device according to the invention thus makes it possible, with a minimal excess of costs compared to conventional sheet parts without additional elements applied by injection, to manufacture sheet parts that offer new functional characteristics as well as possibilities promoting the use and the sale.
    It is also possible to make complete mounting systems with the injection station. For example, functional elements can be injected into the editing process. Modules or switching circuits, for example RFID transponders, can also be coated by plastic injection and sealed. A technical assembly by injection is also conceivable, for example the manufacture of a writing implement by coating a mine by injection of synthetic material which then forms the gripping zone.
    The invention also relates to a method for producing sheet pieces wherein the sheet material is fed to a forming apparatus and is plastically shaped. According to the invention, synthetic material is applied by injection to the shaped sheet piece to form functional elements and / or decorative elements. This results in the advantages explained in connection with the device according to the invention.
    An embodiment of the device according to the invention will be explained in more detail below on the basis of the drawing.
    The single figure shows: a highly schematic representation of a device according to the invention for the manufacture of sheet parts comprising a plurality of machining stations arranged one after the other.
    A device, designated in its entirety by 1, for the manufacture of unrepresented sheet pieces has a sheet roll 2 from which the sheet material 3 is unwound and fed to the various machining stations. After having passed through a heating device 4 to heat the sheet material 3, the sheet material 3 is put into the desired shape in a shaping apparatus 5. The shaping apparatus can be configured in a known manner and having proved its worth and presenting a mold that locally receives the sheet and wherein a male mold penetrates and stretches the heated sheet into the desired shape.
    The forming apparatus 5 is followed by an injection station 6 in which synthetic material is applied to the shaped sheet piece. These applications by injection, injection moldings or injections can be functional elements, decorations or similar injections. In particular for packaging, synthetic material may also be injected into the interior cavity of the shaped sheet piece as a support element or for better holding in position of the object to be packaged in the blister.
    In the figure, a single injection station 6 is shown at this location. However, it can be provided several injection stations arranged behind each other to inject different synthetic materials or to apply synthetic material in different places. The injection stations need not necessarily be arranged in the orientation shown, but may also, for example, be arranged below the sheet material to effect applications on the opposite side of the sheet piece.
    After application of synthetic material to the sheet piece, an object to be wrapped, for example a toothbrush, is inserted into the inner cavity of the blister-type preform in an insertion station 7 and the blister is closed with a layer of cover or cover in another machining station 8.
    In a cutting station 9, recesses or passages are made in the sheet piece and / or in the cover layer, for example display hanger brackets. It is also possible to practice in the sheet piece and / or in the cover layer recesses which will subsequently be covered with synthetic material in another injection station 10. With the second injection station 10, it is possible to It is also possible to apply synthetic material on the lid or the covering layer.
    The sheet pieces which at this stage are still attached to each other and still form a strip of foil are separated in a separation station 11 into individual pieces or packages and are then discharged from the device 1. In the course of the subsequent course From the production, the individual sheet parts or packages can be brought to an outer packaging device to group several parts into a larger packaging unit.
    The order of the different machining stations of the device 1 can be varied depending on the use. Similarly, individual machining stations can be omitted or others can be added. The configuration of the device 1 according to the invention is therefore not limited to the embodiment shown.
