Definitions

• the invention relates to a packaging machine with a transfer device, by means of which a product can be introduced into a package, and with a rotating brochure conveyor device, which has a plurality of pliers-like holders arranged in a row for receiving a brochure and with which the brochure in Area of the transfer device can be brought between the product and the packaging so that it can be inserted into the packaging together with the product, an opening unit with at least one stop being arranged in the transport path of the holder, by means of which the holder can be opened to release the brochure , and wherein the stop is adjustable as a function of an opener signal of a control device between a functional position opening the holder and a non-functional position in which the holder runs past the stop without the prospectus being released.
• a packaging machine of the type mentioned usually has a first rotating conveyor device for the packaging, for example a so-called folding box chain, and a second rotating conveyor device for the products, for example a so-called product chain.
• the movements of the two chains are synchronized in such a way that the product can be inserted laterally into the folding box by means of an insertion plunger in the direction of movement of the chains.
• a brochure or package insert in the packaging.
• a brochure to be inserted into the packaging is moved in the brochure pliers chain between the product and the folding box and is taken along by the product by the lateral insertion movement and inserted into the folding box.
• the pliers-like holder must be opened and the brochure released.
• an opening unit is provided in the area of the transfer device, for example in the form of a stop or opening wedge, on which the pliers-like holder runs during its conveying movement, as a result of which the pliers arms open and the prospectus is released.
• the opening wedge is moved out of the transport path of the pliers-like holder, so that the pliers-like holder with the brochure runs past the opening wedge and is not opened by it.
• the opening wedge then returns to its functional position in order to open the next tong-like holder, provided the conditions necessary for this are met.
• the cycle times that are in a modern packaging machine for a duty cycle available one of only a few million seconds.
• the conditions necessary for adjusting the opening wedge must be detected and evaluated, at least with regard to the product and the packaging, and the actuating device for adjusting the stop must be activated.
• the plunger by means of which the product is introduced into the packaging, is only activated when a product product is available if a brochure is available and it has the correct code and if there is packaging or a folding box.
• the corresponding queries or recordings are carried out in the packaging machine and the corresponding data are available in a data memory, the so-called shift register, and can be called up from this. This data also forms the basis for deciding whether the pincer-type holder is opened or closed to release the prospectus.
• a data record is stored in the packaging machine for each packaging unit, which includes the product, the folding box and the brochure, which contains all the essential status and control data for the packaging unit. Since at the same time a large number of packaging units are processed in the packaging machine and pass through the packaging machine, it is known to store the data records in a common data memory.
• the data memory is designed as a shift register, the data records within the shift register being clocked in accordance with the operating cycle of the machine, i.e. the changing position of the assigned packaging unit in the packaging machine is dragged to the ejection station, i.e. be moved.
• the shift register is clocked via a shift clock, which is usually tapped from the drive of the product chain.
• a packaging machine must be able to process products and packaging of different formats as well as different brochure formats.
• the individual assemblies of the transfer station of the packaging machine must be adjusted relative to each other.
• the brochure pliers chain with which the Tongs opening wedge relative to the product chain and / or the folding box chain adjusted is adjusted relative to the shifting time of the shift register, which defines the start of a processing cycle of the packaging machine.
• the invention has for its object to provide a method for controlling a packaging machine called construction, in which an adjustment of the stop or opening wedge relative to the product chain and / or the folding box chain does not lead to a conflict between the shifting time of the shift register and the opening wedge time.
• This object is achieved according to the invention in a packaging machine with the characterizing features of claim 1.
• the basic idea is to not directly access the aforementioned data of the shift register for the initiation of the opening movement of the tong-like holder, but to use it only indirectly by providing a first detector device by means of which the insertion movement of the product into the packaging is detected and a corresponding insertion signal is emitted to the control device when the product is inserted.
• the control device only generates an opening signal, on the basis of which the opening wedge is brought into its functional position opening the pliers-like holder when an insertion signal is present, i.e. the product is actually inserted.
• a push-in movement of the product only occurs when the slide-in plunger is initiated, which in turn depends on compliance with the above-mentioned conditions (brochure available? Product available? Folding box available? Brochure code correct?). If, therefore, the first detector device detects that the slide-in ram is moved or the product is pushed in, the above-mentioned conditions must all be met. The insertion signal thus indicates whether the prospectus can be released by opening the associated pliers-like holder or not.
• the first detector device can directly detect the insertion movement of the product, but alternatively it is also possible for the first detector device to detect the insertion movement of the insertion plunger which comes into contact with the product.
• the first detector device comprises a first initiator that can be initiated by each slide-in ram passing by and a second initiator that can only be initiated by a slide-in ram that pushes the product in. This configuration is favorable in terms of control technology.
• the first initiator is preferably located in front of the second initiator in the direction of transport and is overrun and initiated by each slide-in tappet, ie regardless of whether the slide-in tappet then carries out a slide-in movement that pushes the product in or whether the slide-in movement is prevented by the slide-in plunger moving away.
• the slide-in ram overflowing the first initiator resets a buffer or flag to a value of 0. If the slide-in ram then begins to slide in the product, it overflows and initiates the second initiator, which sets the buffer to the value 1. An insertion signal is only sent to the control device if the buffer has the value 1. The next slide-in plunger resets the buffer memory to 0 when the first initiator overflows.
• the initiators can be initiated without contact by the push-in plunger, which is particularly the case when the initiators are formed by metal detectors, magnetic switches or light barriers, which are each triggered or switched by the push-in plunger.
• the first detector device and the opening unit can be adjusted together as a unit in the transport direction of the brochure conveying device.
• the mentioned components stored on a common adjustable frame.
• This embodiment has the advantage that when the opening unit is adjusted when there is a format change, for example when the product size is changed, the first detector device with the two initiators mentioned is simultaneously shifted by the same amount, so that the time allocation between the first detector device and the opening unit is retained.
• an additional second detector device can be provided, by means of which the position of the next holder to be opened is detected and which emits a corresponding holder signal to the control device.
• the second detector device thus determines that a holder has reached a predetermined position.
• the control device is evaluated whether the tong-like holder is open due to the receiving slot • signal or to remain closed and whether the is properly aligned open holder. If both conditions are met, the stop or opening wedge can be brought into the functional position or held in the functional position by activating an actuating device in order to open the holder determined by the second detector device.
• the tong-like holder runs past the opening unit or the opening wedge without being opened.
• the prospectus is then removed from the holder at another point in the prospectus conveying device, for example by means of a further stop. dissipated or stored in a suitable manner.
• the second detector device is preferably combined with the first detector device and the opening unit as a unit in the transport device the prospectus conveyor is adjusted. In this way, the spatial and thus also the temporal assignment of the modules is retained after an adjustment.
• the stop is in its non-functional position under spring preload, so that activation of the controllable actuating device is required in order to bring the stop against its spring preload into the functional position or to hold it in this position as long as the necessary conditions for opening the pliers-like holder and releasing the brochure are met.
• the actuating device can be a pneumatic or hydraulic adjusting cylinder.
• the stop or opening wedge is essentially perpendicular to the transport conveyor device and is particularly displaceable.
• a transfer device 10 of a packaging machine is shown in a schematic representation, which has a folding box chain 28 running in the direction of the arrow FK, only shown schematically, for receiving folding boxes or packaging V and a product chain 29 running parallel to it in the direction of the arrow PK, on which products to be packaged P are included.
• the folding box chain 28 and the product chain 29 are synchronized in their movements so that the product P by means of a Nes ram 11 in the transfer device 10 can be inserted transversely to the direction of movement of the chains 28 and 29 in the opened package V.
