Definitions

  • the present invention relates to a packaging machine and a method for packaging goods to be packaged in corresponding packaging means.
  • Packaging machines such as blister machines or cartoning machines usually include storage buffers for holding packaging materials (e.g. folding boxes, cardboard boxes, etc.) or packaged goods (e.g. pharmaceutical products, package inserts or brochures). If such storage tanks are to be refilled by the operator of the machine during the packaging process, he has a display z. B. not in view on the human-machine interface (MMI). Various process parameters that are shown to the operator on the display are therefore not available to the operator, at least temporarily.
  • packaging materials e.g. folding boxes, cardboard boxes, etc.
  • packaged goods e.g. pharmaceutical products, package inserts or brochures
  • the operator therefore does not receive any information about when the end of the batch to be processed is approaching and how much packaged goods or packaging materials are still required until then.
  • the filling level of the large number of packaging means or goods to be packaged in the storage store cannot easily be determined visually.
  • the operator must be able to assess these and other variables well. A lot of experience is required for this.
  • Incorrect assessments and a lack of experience can, for example, lead to the storage tank still being full at the end of the batch to be processed and the then necessary emptying of the storage tank resulting in increased workload.
  • increased filling and emptying can lead to damage to the packaging or packaged goods, which can have a negative effect on their quality on the one hand and negatively on the reliability of the packaging machine on the other.
  • a packaging machine can have a processing unit, the function of which is dependent on the filling level of the packaging material or packaged goods in the storage tank.
  • a trigger can be provided for pulling in leaflets, package inserts, etc., the function and reliability of which depends on the stack height of the stack of leaflet leaflets, package inserts, etc. and thus in turn is based on the experience of the operator.
  • a funnel for feeding pharmaceutical products, the function and reliability of which depends on the filling level of the pharmaceutical products received in the funnel and thus also on the experience of the operator.
  • a packaging machine in which the operator can easily and quickly determine the degree of filling of the storage tank on the basis of the optical marking.
  • the optical marking can also be variably adapted, it can be adjusted by means of the control device to a process parameter that differs from the degree of filling, such as the format, the respective mass or the packing density of the packaged goods or packaging in the storage tank or the batch size, the output rate or an optimal one Adjust the operating point of a unit of the packaging machine assigned to the storage tank. This supports the operator and his experience is less important. The efficiency of the packaging machine and the quality of the packaging process can thereby be increased essentially independently of the experience of the operator.
  • the at least one optical marking can be variably adapted according to the invention as a function of the at least one process parameter different from the filling level, a “process parameter” should always be understood to mean “process parameters different from the filling level”, unless explicitly stated otherwise.
  • the packing density of the plurality of packaged goods or packaging materials is generally defined herein as the number of packaged goods or packaging materials per unit of length (e.g. given in pieces / mm).
  • packaged goods or packaging materials are mentioned herein, this refers to the packaged goods or packaging materials received in the storage tank. If packaged goods are stored in the storage facility, the expression “packaged goods or packaging materials” also refers to packaged goods. If, on the other hand, packaging is stored in the storage facility, this term refers to packaging accordingly.
  • packaged goods are packed in appropriate packaging materials.
  • Packaging can be, for example, folding boxes, cardboard boxes or other containers.
  • Packaged goods can be, for example, products to be packaged, in particular pharmaceutical products, package inserts or brochures.
  • a production or packaging lot, batch, series or lot is referred to herein as a batch.
  • a packaging machine can also comprise one or more further storage buffers, each of which is preferably assigned a further display device and which can accommodate other packaged goods or packaging materials.
  • the packaging machine is preferably a blister machine or a cartoner.
  • the storage device is preferably a folding box magazine for receiving and providing a plurality of folding boxes or a prospectus storage device for receiving and providing a plurality of brochures or package inserts.
  • the supply store can also be a magazine for receiving and providing a plurality of cartons in a cartoner.
  • the at least one optical marking that is indicative of the filling level of the storage tank can be indicative of the absolute filling level of the storage storage device, for example indicating whether the storage storage device is empty or full, or can be indicative of a relative filling level of the storage storage facility, i.e. for example indicative of the Number of packaged goods or packaging materials in the storage tank based on the output capacity of the packaging machine, on the packaged goods or packaging materials required for a batch to be processed or on an optimal fill level of the storage tank.
  • the terms filling level and filling level can essentially be used synonymously.
  • the control device is set up to actuate the at least one optical marking, in particular as a function of the degree of filling of the storage tank.
  • the control device can, for example, switch the optical marking on and off and / or control it in such a way that it changes a property, such as its color.
  • a variably adaptable optical marking is here a marking in which the assignment of the marking to a certain degree of filling of the storage tank can be changed.
  • this assignment can be adapted as a function of at least one process parameter that differs from the filling level, that is to say it can be varied.
  • the optical marking is indicative of an almost empty storage tank, that is, it indicates the degree of filling "empty". If the packaging machine is now operated with a first output rate, the optical marking can be arranged at a first distance from the end of the storage tank from which the packaging means or packaged goods are removed. The optical marking is therefore assigned to a first degree of filling that corresponds to the first distance. If, on the other hand, the packaging machine is operated with a second output that is greater than the first output, the optical marking can be arranged at a second distance from the end of the storage tank from which the packaging or packaged goods are removed, the second distance being greater than the first distance is. the optical marking is then assigned to a second degree of filling, which corresponds to the second distance.
  • the process parameter different from the filling level corresponds in this case to the output of the packaging machine and the optical marking is adapted as a function of the output by being assigned to the second filling level instead of the first filling level.
  • the control device is therefore also set up to adapt the at least one optical marking as a function of the at least one process parameter that differs from the degree of filling.
  • the variably adaptable optical marking is activated accordingly by the control device for adaptation. It is therefore preferably essentially an automatically adaptable optical marking. If necessary, the operator can intervene by means of an input device connected to the control device.
  • the optical characteristics such as the color or the intensity of the marking, or the dimensions, the shape or the (color) progression of the marking can be adaptable.
  • an optical marking is not to be understood as an alphanumeric display.
  • Alphanumeric displays cannot be captured quickly or only with difficulty, and they generally lack any reference to the packaging process or to process parameters, which may be displayed separately. For example, the mere display of the number of packaging materials or packaged goods in the storage tank is not very meaningful without reference to the packaging process and the evaluation of the information depends on the operator and his experience.
  • the at least one display device is not an alphanumeric display. Rather, the display device is set up to display at least one optical marking that differs from an alphanumeric display. In general, the display device is preferably designed separately from an input device or an MMI.
  • the at least one optical marking is a colored marking, the color or color gradient of which can be adapted as a function of the at least one process parameter that differs from the degree of filling.
  • the display device can then be a colored marking or have a plurality of colored markings.
  • the colored marking can have a plurality of different colors which are essentially separated from one another or which continuously merge into one another and thus form a color gradient.
  • each color can be assigned a certain degree of filling of the storage tank. This assignment can be variable to form a variably adaptable marker.
  • the color or the color gradient can be adapted as a function of the format or the packing density of the packaged goods or packaging means in the storage store, as described herein.
  • the display device is preferably arranged on or in the storage tank.
  • the display device is preferably arranged in an area that is easily visible to the operator of the packaging machine, in particular while the operator is filling the storage tank.
  • the display device is therefore preferably not attached to the MMI or formed by the MMI, but rather formed separately from an input device or the MMI.
  • the display device can, however, also be arranged at a distance from the storage tank. Here, too, it should be clearly visible to the operator of the packaging machine, in particular while the latter is filling the storage tank.
  • the display device or at least the optical marking is arranged along the plurality of packaged goods or packaging means in the storage store.
  • the at least one optical marking can be at least partially in contact with the packaged goods or packaging means or can be arranged in the immediate vicinity of these, so that the marking and the packaged goods or packaging means can be detected jointly by the operator.
  • the filling level of the storage tank can be determined quickly and easily by looking at the packaged goods or packaging in the storage tank.
  • the display device or at least the optical marking can be partially covered by the plurality of packaged goods or packaging means. It can thus be seen directly how far the majority of packaged goods or packaging means in the storage area extend along the optical marking.
  • the display device or the at least one optical marking can be designed as a light strip, for example.
  • a light strip can comprise a light field or a plurality of light fields, in particular a plurality of LEDs. If the light fields of the plurality of light fields are individually controllable, the light strip forms a corresponding plurality of optical markings.
  • a light strip which is also generally referred to as a light strip, can be particularly simple along the plurality of packaged goods or packaging means are attached in the storage tank and optionally be partially covered by the plurality of packaged goods or packaging means.
  • the light strip does not necessarily have to include individually controllable light fields.
  • Individually controllable light fields offer the advantage that the optical markings formed by them are designed to be particularly simple and variably adaptable. For example, each light field can be switched on or off independently of the other light fields, or the individual light fields can have different colors, which can also be easily changed and thus adapted as desired.
  • An optical marking formed along the plurality of packaged goods or packaging means can, for example, have a first color (e.g. green) in an area of the storage unit in which only packaged goods or packaging material are arranged if the storage unit is sufficiently full is. This depends on the format of the packaged goods or packaging materials and their packing density in the storage facility. If the storage device takes on other packaged goods or packaging means in a different packaging process, the section of the optical marking which has the first color can be adapted accordingly as a function of its format or packing density.
  • a first color e.g. green
  • the section of the optical marking with the first color can be arranged closer to one end of the storage unit at which the packaged goods or packaging materials are removed from the storage unit for further processing will. Since in the case of thicker packaged goods or packaging materials or with a lower packing density, fewer packaged goods or packaging materials are arranged along the same route, the section of the optical marking with the first color would then have to be arranged further away from this end of the storage tank.
  • the optical marking in an area near one end of the storage tank, where the packaged goods or packaging are removed from the storage storage for further processing can have a second color (e.g. red) to indicate that the storage storage is almost empty.
  • a second color e.g. red
  • the section of the optical marking with the second color can also be adapted accordingly.
  • the display device comprises a light strip which extends along the storage reservoir, a corresponding color can be assigned to each section in a simple manner, for example.
  • the at least one optical marking can be projected onto the plurality of packaged goods or packaging means. This also allows the filling level of the storage tank to be recorded particularly quickly and easily by looking at the packaged goods or packaging in the storage tank. In addition, the optical marking can be easily adapted as a function of the at least one process parameter.
  • the display device is designed as an optical signal device, in particular as a traffic light or signal column on the storage tank.
  • the optical signal device preferably comprises a plurality of optical markings, in particular in the form of separate light fields. These light fields can for example be arranged one above the other.
  • the optical signal device can be set up to display two or more (filling) states of the plurality of packaged goods or packaging means in the storage store.
  • the optical signal device is set up to indicate a fill level of the storage tank in the form of a height of a stack of packaged goods or packaging materials, in particular brochures or package inserts.
  • the optical signal device can be set up to identify a fill level of the storage tank in the form of a quantity of packaged goods, in particular pharmaceutical products.
  • the process parameter which differs from the degree of filling, can be, for example, an optimal operating point of a removal device (for example a fume cupboard) assigned to the storage tank.
  • the optimum operating point can in turn be dependent on the type and material of the packaging material or packaged goods received in the storage tank or a withdrawal speed of the removal device.
  • the optimal operating point when using a first packaging means, can correspond to a first stack height to which the at least one optical marking is assigned, while the optimal operating point when using a second packaging means can correspond to a second stack height corresponds to which the at least one optical marking is assigned.
  • the at least one optical marking is adapted independently of the actual filling level of the storage tank as a function of the optimal operating point.
  • the optical signal device can comprise a first light field which lights up when the height of the stack corresponds to a predefined optimum height and thus to a first degree of filling which it identifies. If the height of the stack deviates from the optimal height, but is still within a tolerance range, a second light field of the optical signal device can light up. The second light field is therefore assigned to a height within the tolerance range and identifies this. If the height of the stack is outside the tolerance range, a third light field of the optical signaling device can finally shine, which is assigned to a height outside the tolerance range and identifies this. The second light field thus enables the operator to be warned in advance and the third light field signals the need for action to the operator. It is also conceivable to provide only two light fields that signal whether the height of the stack is within or outside of the tolerance range.
  • the storage unit can also be formed by a funnel, which at the same time forms a feed for the received packaged goods (e.g. pharmaceutical products) and thus also forms a removal device directly assigned to the storage unit.

  • an MMI 16 can include a display for displaying process parameters.
  • the second supply store 6 receives a plurality of packaged goods or packaging means 18, here a plurality of brochures 18, and makes them available for further processing.
  • a removal device assigned to the second storage tank 6 is designed as a trigger 20 in this case and an uppermost prospectus 18 is produced in each case withdrawn from the plurality of brochures 18 by means of the trigger 20 and fed to the further process.
  • the packaging machine 2 comprises a second display device 22 which is assigned to the second storage tank 6 and which is set up to display at least one optical marking.
  • the second display device 22 is also connected to the control device 14 in a communicating manner.
  • the second display device 22 is designed as a traffic light which has a first optical marking 22a, a second optical marking 22b and a third optical marking 22c.
  • the first, second and third optical markings 22a, 22b, 22c are preferably arranged one above the other.
  • a signal tower could also be used, for example.
  • the first optical marking 22a preferably has a first color
  • the second optical marking 22b has a second color
  • the third optical marking 22c has a third color
  • the optical markings 22a, 22b, 22c are indicative of the filling level of the second storage tank 6. For example, the first color signals to the operator that the second storage tank 6 is sufficiently full, and the third color signals to the operator that the second storage tank 6 is empty or is almost empty. The second color can then indicate an intermediate state or a tendency towards an empty storage reservoir 6.
  • At least one optical marking of the second display device 22 can be adapted as process parameters, for example depending on the format of the packaged goods 18, on the packing density of the packaged goods 18 in the second storage store 6 or on the output of the packaging machine 2. For example, switching from the first to the second optical marking 22a, 22b and from the second to the third optical marking 22b, 22c can be done earlier due to an increased output rate, i.e. with a larger number of packaged goods 18 in the second storage store 6 and thus with a greater fill level. Any optical mark 22a, 22b, 22c can thus, for example, be assigned to a different, specific filling level of the storage tank 6 within the framework of the adaptation.
  • the trigger 20 works error-free at an optimal operating point, e.g. at an optimal height H of the stack of brochures 18 in the second storage store 6, while the reliability of the trigger 20 decreases in the event of deviations from the optimal operating point.
  • the first optical marking 22a can be assigned a degree of filling which corresponds to a stack with an optimal height H.
  • a tolerance range T can be determined in which the trigger 20 operates with sufficient quality and reliability.
  • the second optical marking 22b can then be assigned to a degree of filling that is within the tolerance range T. If the degree of filling of the second storage tank 6 is outside the tolerance range T, this can be identified by the third optical marking 22c, which is assigned to such a degree of filling.
  • the optimal operating point can, for example, be dependent on the type and material of the packaged goods 18 and on the output rate of the packaging machine 2 and the associated withdrawal speed of the withdrawal 20 as process parameters.
  • Each optical marking 22a, 22b, 22c can therefore be adapted as a function of at least one process parameter, for example by assigning it to a different height H and consequently adapting its activation time.
  • the packaging machine 2 after Fig. 2 further comprises a database 24 which is connected to the input device 16 and / or the control device 14 in a communicating manner.
  • Process parameters and empirical values can be stored in the database 24, which can be called up by the control device 14 and used to adapt the respective optical marking.
  • an operator can select process parameters or enter process parameters and empirical values and store them in the database 24.
  • the packaging machine 2 furthermore comprises, independently of the database 24, a first sensor 26 which is connected in a communicating manner to the control device 14 and which is set up to determine a first process parameter and to provide it to the control device 14.
  • the first sensor 26 is assigned to the first storage unit 4 for determining the packing density of the packaging means 8 in the first storage unit 4.
  • the packaging machine 2 can also comprise a second sensor 28 which is connected to the control device 14 in a communicating manner and which is set up to determine a second process parameter and to provide it to the control device 14.
  • the second sensor 28 is assigned to the second storage tank 6 and determines the filling level or the height H of the packaged goods 18 in the second storage tank 6.
  • the sensors 26, 28 can consequently be used to detect a process parameter independent of the filling level for adapting the at least one optical marking or to provide the control device 14 with information about the filling level of the respective storage reservoir 4, 6 for actuating the at least one optical marking.
  • sensors 26, 28 can also be provided for determining further process parameters which do not necessarily have to be assigned to a storage memory.
