H. With Packaging machines with a plurality of rotating heads (Workstations) for product taking, handover and packaging of the products are provided, so that the articles in a continuous process and with high performance depending on product type and wrapping type (packaging type) as well as other boundary conditions packed with up to 1200 cycles per minute become.

Indeed are such high packaging services often only in the packaging relatively easier, such. B. reach parallelepipedförmiger shaped products reachable and often require a custom design and configuration the individual article-carrying and involved in the packaging process Working heads of the machine, allowing for different Types of packaging (types of impact) or small series of such machines no sufficient variability or easy conversion, not only on the part of the manufacturer, but also for have the user.

So far are in such packaging machines or packaging systems generally only the product feed and product separation, e.g. B. in conjunction with a plate feeder, a band or chain feeding or processing of the mass strand variably convertible while the product guide and orientation by the packaging machine itself substantially constant and by the given structure of the rotating heads.

Examples of product packaging lines of the Applicant with tape feed, work from the strand of material or with plate feed are in the 16 to 22 shown.

In addition to changes the article feeder and separation it is also known within the packing stations the pack head different packaging components depending on the selected impact type assigned. However, in this case remains the basic structure the respective packaging machine, in particular the product orientation constant through the machine during the course of the article, d. H. the regime the transfer of the articles within the machine remains, due to the configuration of the heads, unchanged.

Of the Invention is therefore based on the object, the aforementioned disadvantages to eliminate and a method and a packaging machine, in particular to carry out the procedure, which make it possible an unprecedented diversity with regard to the workable Product formats and sizes as well as types of folding (folding types), also in combination with each other and in combination with different ones Feeding and separating systems with high variability the orientation of the articles within the packaging process so that such a method and such a packaging machine with sufficient performance for the user of higher utility value than in previous systems due to the rigid design of the interlinking and the article-bearing Packaging facilities within the packaging machine is the case.

The explained below embodiments of the Invention are both for continuous working Packaging machines with two article-carrying packaging devices, where the article gripper station directly accesses the or separating system coming, separated article receives and in the same or changed orientation to a packaging station from which the packaged articles are to be conveyed, or for packaging machines with three or more article-carrying Packaging Applicable, in which a removal wheel for Receiving the articles from a feeding or separating device and passing it on in the same or changed orientation to an article gripper station with an article gripper head, the Packing material is supplied, is provided by this second head in the same or changed orientation to deliver the article together with the piece of packaging material to the packing station become. Optionally, also in the sense of a packaging machine with four article-carrying packaging devices to the packaging station yet a dispensing wheel for the orderly storage of the packaged articles on one Abförderband (bridge band) join.

1a shows a schematic side view of a basic type of packaging machine 100 according to a first embodiment, in which case only one packaging station 40 with a packaging head 41 and opposite turning stations 42 . 43 is shown, as used for the production of packages in the double-twist wrap (with two rotary blades). The absence of a removal station (see withdrawal station 20 in 1b ) or an article gripper station 30 (see. 1b ) should be in the 1a indicate that these article-carrying packaging facilities variably designed and optionally to complete the packaging machine 100 this can be added (three-head packaging machine) or even that only one article gripper station 30 rotatable about a central stationary axis of rotation 1 is additionally used in training the packaging machine 100 as a two-head packaging machine.

1a therefore illustrates the modular basic concept of the packaging machine 100 ,

However, this does not mean that the packaging station 40 or the packaging head 41 Not also, as well as the additional impact means (turning stations 42 and 43 ) could be interchangeable. Of these, however, in rarer cases, what the pack head 41 relates, made use of, while the interchangeability of the impact type determining additional stations within the packaging station 40 , here the turning stations 42 and 43 , the expert is familiar. The representation regarding the assembled packing station 40 in 1a is therefore not intended to be limiting or prejudicial.

Optionally, therefore, as in 1 in particular for a removal station 20 and an article gripper station 30 indicated, these heads in various configurations, in particular with regard to an orientation of the article when passing through the packaging machine 100 interchangeable and may preferably be the removal station 20 with the article gripper station 30 merge (two-head packaging machine). However, it is also an interchangeability of the packing head 41 within the packaging station 40 intended.

1b shows in principle and in front view of such an embodiment of the "prototype" 1a as a three-head packaging machine with three article-carrying packaging devices (namely the removal station 20 , the article gripper station 30 and the packaging station 40 ). In these workstations are indicated accordingly and here only schematically, a removal head 21 , an article rapier head 31 and a packing head 41 intended. Their direction of rotation is indicated by arrows in 1b indicated.

In the context of the present application, therefore, on the one hand in a two-head packaging machine, an article gripper station is used as the removal station or else as the removal device 30 with an article rapier head 31 as well, in the event that the removal station 20 Part of a three-head packaging machine is, as in 1b shown a pickup wheel 21 denotes the article from a feeding and / or separating device 10 receives.

In 1c to 1e are examples of such feeding and singulating devices 10 schematically as a plate feeder with separating plate 7 in 1c , Band or chain feed with a linear feeder 8th in 1d or a strand feeder 9 in 1e shown.

Such feeding and separating devices are mechanical with the packaging machine depending on the product type and feeding system 100 coupled and driven by at least one decentralized, separate drive, as is conventional.

The packaging machine 100 This distinguishes itself in its modular structure that a central axis 1 on a machine frame 2 the packaging machine 100 is set to the one n-part workstation, namely the article gripper station 30 with the article rapier head 31 is rotatable and to which a packaging material material not shown here is supplied from a packaging material supply device, also not shown here, to apply to a respective article and with this to the packaging station 40 to be passed on. It has already been noted that the packing station 40 with the packing head 41 , here with opposite turning stations 42 and 43 fitted, of course, is not limited to such an embodiment, but other folding stations or folding heads opposite to the packing head 41 , or combinations of folding stations and turning stations, z. B. for a top-twist folding, as explained below, within the packaging station 40 in conjunction with the packing head 41 can be provided. It is again pointed out that even the packing head modular exchangeable on the machine frame 2 in a different embodiment, for. B. depending on the size of the article to be packaged, is provided.

In the present embodiment, the axes are between folding station 40 and article gripper station 30 arranged offset at an angle α of approximately 20 ° to each other and the packaging station 40 is laterally offset above the article gripper station 30 ,

This angular offset may be within the overall design of the packaging machine 100 However, changed, especially in a range of about 10 ° to about 60 ° can be selected.

Schematically are in 1b another, the packing head 41 possibly assigned folding stations 11 or folding organs as possible components of the packaging machine 100 illustrated, which make it possible, other types of impact, such. B. to realize stanolization.

Of others can also have additional functions in this area be realized, such as the provision of Aufreißhilfen packaged articles, label dispensers or closure aids for the packaging (glue point).

According to the continuous working principle, both the sampling station 20 , formed here by a removal wheel 21 a plurality of each pivotally mounted on the picking wheel 21 stored holding jaw pairs to order items from one of Receive feeding or singulating and to the article gripper station 30 to pass on their article rapier head 31 also with corresponding, in the context of the present application usually referred to as gripper jaw pairs holding jaw pairs having. The packing head has the same way 41 the packaging station 40 Holding jaw pairs for fixing the articles, without this being shown here. Particular features of the present embodiments will be discussed in more detail below. Essential in the context of this embodiment is the interchangeable, ie interchangeable storage at least one of the three article-carrying packaging facilities, here the removal station 20 , the article gripper station 30 and / or the packaging station 40 ie a withdrawal wheel 21 and / or an article rapier head 31 and / or a packing head 41 , in adaptation to an article type or article orientation or a selected type of packaging (impact type), as will be explained in more detail below.

Even though this is not explained or shown here, the packing head can also have other configurations and z. B. be equipped with rotating folding shafts, under transfer the article between article gripper station and packing head by means of expandable transfer stamp.

The packing station 40 with the packing head 41 is rotatable about a second fixed axis (packing head axis) 44 and with 12 is in 1b a dispenser for the (in this case unordered) discharge of packaged articles from the packaging machine 100 designated.

With such a modular structure of the packaging machine 100 , in particular removal wheel 21 , but possibly also article rapier head 31 or packing head 41 is concerned, depending on the desired product impact high flexibility also with regard to an orientation of the articles within the packaging machine 100 , the control of the corresponding holding members (gripper jaw pairs) are selected depending on the article type, so that even in small series such a packaging machine, which preferably works in the mid-range up to 800 products per minute, both manufacturers and users quick changeover of the packaging machine is given , in terms of formats as well as in terms of feasible types of wrapping and packaging types in great variability and variety.

Unlike previous solutions, in the present packaging machine 100 z. B. not only the turning station 42 . 43 (Or there alternatively proposed folding station or two folding stations) depending on the type of impact on the Packkopfachse 44 can be changed, or can be different units such as singulator 7 , Belt or chain feed 8th or strand feed 9 as feeding or separating device 10 for the articles at the entrance of the packaging machine 100 be provided, but it is in particular the removal station 20 with the removal wheel 21 and / or the article gripper station 30 with the article grab pot 31 and / or the packaging station 40 with the packing head 41 and associated stations such as turning station 43 replaceable on the machine frame 2 the packaging machine 100 stored and with reference to the "fixed point" on the machine, namely the central axis 1 to combine different types of articles, article orientations and types of impact in a highly flexible manner combinable. It can also be provided that the packaging machine 10 , as in 1a indicated, the packing head provides as a fixed workstation, so that only the article gripper station 30 (Two-head) and / or the removal station 20 (Removal head 21 ) interchangeable on the machine frame 2 is. Ie. Also, a combination of predetermined, solid article-carrying packaging devices, arranged with interchangeable and as a supply of article-carrying, rotating heads is possible.

It is preferably in connection with the central axis 1 a central transmission, not shown here provided by the also by means of cams, the movements of the article rapier head 31 including those of the associated gripper jaws, and preferably also a drive control for the packaging station 40 derived from this central transmission. In a similar way, the removal station 20 with a drive, derived from the central transmission, cam controlled. However, it is also possible in particular with regard to the modular machine concept, the drives for the article-carrying packaging devices 20 . 30 and 40 to decentralize and separate, z. B. based on individual servomotors, under control by a central control unit (CPU) to realize. The drive of the dispenser 12 is also decentralized.

Furthermore, also required motion controls within the article-carrying packaging facilities 20 . 30 . 40 , in particular in the field of packaging station 40 , If necessary, further motorized actuating means such as micromotors, possibly also be provided as a hybrid motion control devices in conjunction with cam-controlled elements or be carried out in a conventional manner cam-controlled.

Thus, a highly flexible transport of the articles from the selected supply and treatment device 7 or 8th or 9 taking into account ensure the nature of the article and the type of wrapping (type of packaging), and in particular by exchangeable picking wheels 21 in the removal station 20 realized as explained below. The picking wheel 21 has the function of removing the articles from the feeding or separating device 10 for transfer to the article rapier head 31 , whereby for certain types of impact also an orientation of the articles can be changed.

For certain product orientations will also be on the central axis 1 located article rapier head 31 replaced and, if necessary, an exchange of the packing head 41 , in particular in connection with associated stations such as a folding station or turning stations 43 , intended.

Depending on the article feeding and orientation as well as article separation, the in 1a and 1b shown packaging machine 100 with three article-carrying heads (removal wheel 21 , Article rapier head 31 , Packing head 41 ) in a two-head packaging machine (see. 7 ), which is characterized by a very product-friendly design, and z. B. for the packaging of lollipops from the EP 1 712 472 A1 , the contents of which are incorporated by reference into the subject matter of the present application is known. Such a two-head packaging machine is preferably used in conjunction with a separating principle explained below in more detail for receiving the articles from a separating plate 7 and transfer directly into the article rapier head 31 explained. In this case, so on a special picking wheel 20 waived.

The modular nature of the packaging machine 100 also comes with regard to an optional usability further, on the periphery of the packing head 41 arranged folding organs or stations 11 expressed for special impacts, such. B. stanols may be provided, or additional functions such as tear-open, label dispenser and packaging closure aids (glue point) realize.

The dispenser 12 also forms a separate modular unit with its own drive, preferably an ordered or a, as in 1b shown schematically, unordered article delivery can be done. In the case of the disorderly discharge shown here, the articles are delivered via an ejector in the packing head 41 on a delivery belt of the dispenser 12 promoted. In the case of an ordered delivery, however, the articles are transferred from the packing head via a transfer wheel (not shown here) 41 taken and defined on a web strip of the discharge 12 stored.

The following is based on the 2 to 6 an embodiment of a novel product or article removal from a separating plate 7 , the here the feeding and separating device 10 forms, for a two-head packaging machine 100 explained. However, such a submission can be applied in a comparable manner also to a three-head packaging machine in which the articles from the separating tray 7 not directly into the article gripper station 30 with the article rapier head 31 but first to the removal wheel 21 be passed that then instead of the article rapier head 31 as removal station 20 acts. It is dependent on the product type in the rest z.

As 2 clarified, is in the present embodiment of the article 13 through the gripper jaws 33 clamped at its ends and detected by the gripper jaw pair in question 33 . 33 accepted.

The discharge device 50 is described below on the basis of 3 to 6 explained in more detail.

It points next to a about a pivot axis 52 swiveling upper punch 51 as the main component a Unterstempelrad 53 on (cf. 4 ), the how 6 clarified, below the separator 7 is arranged such that of the Unterstempelrad 53 the eccentrically worn lower punches 54 In the present case, there are three lower stamps 54 , alternately and depending on the pitch of the receiving pockets and the rotational speed of the separating actuator 7 in stable vertical orientation (s. 4 - 6 ) from below into the receiving pockets 12 dive in and the articles 13 from the receiving pockets 12 lift out, for transfer to the gripper jaw pairs 33 . 33 like that too 3 clarified.

For storage of the article 13 while being lifted out by the lower punch 54 serves the upper stamp 51 , whose movement by an unspecified illustrated here Oberstempelgetriebe 55 is ensured.

Alternatively, it is also possible by positive support of the article 13 on the lower stamp 54 , ie by forming a surface of the same in adaptation to the article in question 13 and forming an article guide and support geometry on the lower die 54 , on the stock-safe upper stamp 51 to renounce completely and the articles 13 without such a position assurance in the movement path of the additional about the axis 34 pivoting and with the article rapier head 31 circumferential gripper jaw pairs 33 . 33 provide. In the present version, the articles 13 initially within the separator 7 (Hole plate) in the receiving pockets 12 isolated, the articles 13 through the separator plate 7 in the direction of the arrow (counterclockwise) in the circumferential direction further promoted while a Auflagerring 6 transported, ie pushed. Alternatively, the articles can 13 also directly through the separating plate, z. B. in form-fitting shaped receiving pockets, stored and fully supported by this again who the. The article rapier head 31 , as shown by arrows also in the 2 and 3 shown, clockwise.

The receiving pockets 12 of the separator 7 are the shape of the article 13 adapted and z. B. round, oval, square or rectangular. Products with rectangular or oval basic configuration and base area can be either left (tangential) or transverse (radial) to the direction of movement through the separating plate 7 be transported. In the present case, the articles 7 of rectangular configuration and are radially oriented in the separator plate 7 or the receiving pockets 12 arranged so that they are from the gripper jaws 33 . 33 along its length after provision by the discharge device 50 be clamped.

Accordingly, in the case of transport along the direction of movement of the separating actuator, the receiving pockets thereof are arranged in the tangential direction on the circumference or, as in the present case, for transport with an article main axis transverse to the direction of movement, the receiving pockets are arranged in the radial direction, so that in the present Embodiment the type. 13 transverse to its transport direction to the article rapier head 31 be handed over.

As the 4 to 6 clarify, and also by the article handover, as they are based on the snapshots in the 2 and 3 is clear, is shown, the Unterstempelrad 53 in the present case, with three sub-stamps 54 provided in the Unterstempelrad 53 are stored and driven so that they are during one entire revolution of the Unterstempelrades 53 always in a vertical position, ie with the stamp surface facing upwards.

Accordingly, they lead a dipping movement into the receiving pockets 12 of the separator 7 , matched to the division of the receiving pockets 12 and the peripheral speed of the same to each successively an article 13 from the associated receiving bag 12 and to the article grabber head 31 ie to the gripper jaws 33 . 33 to hand over.

To control the movement of the position of the lower punch 54 serves a special punch gear 60 with special gear arrangement, how they look 5 is apparent.

The lower stamp 54 are together with an associated guide gear 56 through waves 57 stored, with each guide gear 56 the same number of teeth as a central, stationary and fixed to the frame arranged sun gear 58 , At this relies on every guide gear 56 a drivable intermediate gear 59 in that the guide gear 56 rotating drives. The intermediate gears 59 are just like the waves 57 in the housing of the Unterstempelrades 53 stored. The number of teeth of the intermediate gears 59 is arbitrary. The lower stamp 54 are preferably eccentric with the waves 57 or the respective associated guide gear 56 connected. The lower stamp 54 However, their point of articulation can also be on the axis of the waves 57 or centrally to the shaft-fixed guide gear 56 have, as is the case in the present embodiment.

An eccentric linkage of the lower punches 45 has the advantage that in this way the hub, the lower punch 54 for lifting the article 13 from the receiving bag 12 run, can be increased. Of course, such a prolonged period of immersion of the lower punch 54 in a respective receiving bag 12 in the design of the division of the receiving pockets 12 and in the tuning of the rotational speeds of Aufgabering 7a and lower punch wheel 53 be taken into account.

Preferably, the degree of eccentricity of the bearing is the lower punch 54 Adjustable, so that also the size of the stroke of the lower punch in adjustment to the size of the item 13 as well as a situation of taking over picking or gripper wheel in a wide range is variably adjustable, up to the possibility of the lower punch 54 equip with a different Ausförderhub.

As 6 clarified, the lower stamp approach 54 on a circular track from below the receiving pockets 12 of the separator 7 , wherein in the region of the arrangement of the Unterstempelrades 53 the bearing ring 6 is interrupted to give room for a free passage of the lower punch 54 in the respective receiving bag 12 of the separator 7 ,

Moreover, by a in 3 clarified, conical outlet area 6a of the support ring 6 ensured that between bearing ring 6 and adjacent lower stamp 54 only a narrow gap occurs, so over this gap the article 13 from the support ring 6 on the lower stamp 54 is pushed, how 6 clarified.

The functioning of the discharge device for transferring an article 13 from the separating plate 7 to the article rapier head 31 is as follows:
At the beginning of an upward movement of the relevant lower punch 54 the upper punch moves 51 via an article-filled storage bag 12 of the separator 7 so that it forms a closed chamber containing the article in question 13 fixed in a form-fitting manner. In the further course of the upward movement (cf. 3 ) becomes the article 13 between lower stamp 54 and upper stamp 51 clamped and thus kept safe. The opened holding jaws, ie the gripper jaws 33 of the article gripper head functioning as a removal unit in this case 31 move into one of the side surfaces of the article 13 opposite position. This is done from the side above in connection with the rotation of the article rapier head 31 or an additional pivoting movement of the article station 35 around the axis 34 ,

In the transfer position, as in 3 clarifies, the clamping between the lower punch 54 and upper stamp 51 relaxed with simultaneous clamp detection of the article 13 at its opposite end faces by the gripper jaws 33 which now has the guidance and support of the article 13 take.

The further embodiment for a two-head packaging machine 100 to 7 shows the possibility of a belt or chain feed 8th as a feeding and separating device and clarifies, as already based on 1 explains, at the same time the angular offset between the packing head 41 and rapier head 31 , The arrows are in 7 the direction of movement of longitudinal conveyor 8th as well as article gripper station 30 and packaging station 40 indicated. Preferably, the linear feed device 8th (Feed belt and / or chain) a not shown here in detail Stauband and directly in the transfer areas to the article rapier head 31 provided delivery tape or delivery chain, in which the articles 13 to a discrete article distance in accordance with the pitch of the gripper jaws 33 on the article rapier head 31 and taking into account the feeding speed and rotational speed of the Greiferbackenpaare 33 of the rapier head 31 are isolated. With regard to such a tape feed 8th to a two-head packaging machine 100 the supply of the article takes place here from one side, the one in a three-head packaging machine still shown below 100 is opposite, ie in the representation of 7 from the right, while with the arrangement of an additional removal wheel 21 (Three-head packaging machine, s. 1b ) such a tape feed from the left is provided.

Of course, also for a three-head packaging machine, an article feed with the help of a separating actuator, as described above with reference to 2 to 6 was explained.

The longitudinal conveyor 8th in 7 Optionally, it may also be a chain feeder. According to the embodiment 7 is the orientation of the article preferably transversely to the transport direction and as wrapping can be z. B. a bag folding with a fold impact on the bottom and a twist wrapping be provided on the head of the product, by appropriate training of the packaging station 40 , as in 12 shown.

Below are further embodiments of the packaging method according to the invention as a suitably designed packaging machine 100 with reference to a three-head packaging machine, wherein, as in the schematic representation of 1b three article-carrying packaging devices, namely the removal station 20 with the removal wheel 21 , the article from a feeding and / or separating device 10 an article gripper station 30 with the article rapier head 31 containing the recorded items 13 with the assignment of a piece of packaging material, namely to a packaging station 40 with a packing head 41 in which the packaging of the article takes place. Preferably in the removal station 20 and / or in the article gripper station 30 In this case, changes in the article orientation are provided in the packaging process, while the article orientation generally in the packing head 41 is not changed, but also should not be excluded.

In 8th is a first embodiment of the procedure with reference to the packaging of an article 13 schematically illustrated in the double twist, wherein in a similar manner also sealed packaging "Protected Twist" or sachet folds (sachet) can be performed and this method by using a removal wheel 21 as removal station 20 is characterized by which the articles 13 without changing the orientation of a feed belt 8th , consisting of Stauband 8a and separating band 8b recorded and without changing the article orientation on the article rapier head 31 in the article gripper station 30 be passed on. The process or packaging process the packaging of here hemispherical chocolates 13 in double-twist is in 8th illustrated schematically, the corresponding device-related embodiments are not shown, but each with the help of holding or gripper jaw pairs, preferably cam-controlled, done. After the recording in the separation band 8b isolated article 13 and guiding it without changing direction in the picking wheel 21 These are attached to the gripper jaws of the article rapier head 31 pass, taking the article rapier head 31 at the same time the packaging material, ie a piece of packaging material 5 is fed, and this to the article 13 is created, with the help of a packaging tongs 36 (please refer 2 . 3 ). Before that is the article 13 rotated by 90 °, as the between article intake and shooting of the piece of packaging material 5 rotated position of a bottom surface of the article 13 clarified. Since these are chocolate coated items 13 acts, the piece of packaging material 5 in turn, two-ply with an inner wrap 5a and an outside impact 5b formed, both pieces of packaging material 5a . 5b are immediately stuck together (the piece of packaging material 5a is opposite the piece of packaging material 5b shortened in length) to the article 13 introduced as the schematic in 8th indicated, in the usual but conventional. A packaging material supply device is with 4 designated.

In the packing head 41 becomes after assumption by appropriate holding jaw pairs from the gripper jaws of the article rapier head 31 first a packaging tube 13a formed, as shown schematically in 8th is shown, before not shown here, both sides of the packing head 41 arranged turning stations provide for a double-twist of the article, which is then disordered on a delivery belt of a discharge device 12 is dropped over an ejector, not shown here.

9 shows a further embodiment of the packaging machine 100 or for the packaging method, wherein the removal station compared to the embodiment according to 8th is exchanged, ie a picking wheel 21 ' instead of the removal wheel 21 on the machine frame 2 the packaging machine 100 is used. This unloading wheel 21 ' now allows a change of article orientation by way of inclusion of the article 13 from the singulation band 8b to the article rapier head 31 , in which the piece of packaging material 5 being fed, taking as the arrows in 9 regarding the removal wheel 21 ' clarify that an additional rotation of the article 13 about a transverse axis or about an axis parallel to the axis of rotation of the removal wheel 21 ' or a pivot axis of the associated holding jaw pairs, takes place substantially at 90 °. For this purpose, the holding jaw pairs of the removal wheel 21 ' In addition to its pivotability again rotatable about a further axis, so that there is a quasi "gimbal" suspension or storage for the article holder.

A corresponding structure of an article unit 22 for an article 13 at the removal wheel 21 ' becomes below with reference to 11 explained, wherein the 1a and 11b each one view from downstream and upstream of the article unit 22 to point to this. After delivery of the article 13 to an article gripper station 30 ' will be in the example 9 another rotation of the article 13 in the article gripper station 30 made, in other words, according to the embodiment according to 8th and 9 also another article rapier head 31 ' used in this embodiment, such that a rotation of the article orientation takes place by 90 ° about a radial vertical axis of the corresponding gripper jaw pairs. This is also due to the opposing arrows in the area of an article 13 of the article rapier head 30 ' indicated.

So while the article 13 after a turn in the picking wheel 21 ' (Rotation about a parallel axis to the rotation axis of the removal wheel 21 ' ) occupies a position in which a bottom surface of the article 13 in the direction of a trajectory of the article 13 is directed by rotation about a vertical axis by appropriate cam controlled control of the articles 13 Article gripper head holding claw jaw pairs 31 each article is rotated there so that it occupies a position in which its bottom surface facing outwards, so practically in the direction of the central axis 1 of the article rapier head 31 ' has.

Again, as in 9 shown schematically in the article rapier head 31 ' the piece of packaging material 5 to the article 13 created by means of the packaging tongs, not shown here 36 held and in this configuration to the packing head 41 passed, with its holding jaw pairs the article Stetes with U-shaped folded piece of packaging material, ie without direct contact of the article 13 , but always from the outside with the interposition of the already U-shaped folded piece of packaging material 5 terminals. This is a particularly gentle capture handover of the article 13 realized.

Before an explanation of an embodiment for the realization of the additional article rotation in the picking wheel 21 ' according to 11a and 11b takes place, is still based on a further embodiment according to 10 be referenced that, as well as 9 , z. B. is suitable for a top-twist impact and in which a third type of picking wheel 21 '' is used. Again, the articles 13 from the singulation band 8b detected and recorded by appropriate removal-holding jaw pairs. In the first wheel, ie in the unloading wheel 21 '' become the articles 13 but tilted or rotated about a tangential axis by about 90 °, so that after this rotation or tilt by appropriate pivot control of the removal-holding jaw pairs about a tangential axis on the picking wheel 21 '' a bottom surface of the article 13 has direction, ie in the direction of the corresponding axis of rotation of the removal wheel 21 '' like this in 10 is clarified. Such a position, either by additional rotation within the second head, ie within the article removal head 31 ' to 9 takes place, or even according to the embodiment of 10 is effected, in which case a rotation in the second head, ie in the article rapier head 31 , is dispensable, is a prerequisite for a realization of the folding style "Top Twist", as in the 9 and 10 shown.

The individual variants can be mixed in a corresponding manner depending on the selected type of impact and combined with each other, so that the article 13 at the beginning of the wrapping through a piece of packaging material 5 in the respectively "correct" situation with regard to the packing in the packing head 41 is.

The with regard to a rotation of the article 13 in the unloading wheel 21 ' already mentioned "gimbal" storage of the article 13 will be described in detail with reference to the associated embodiment of the picking wheel 21 ' in the 11a and 11b explained. It is also preferred that this rotation of the article 13 can be stopped by rotatable holding jaws, so that optionally in conjunction with the respective assignment of an article rapier head 31 or 31 ' , so with additional article rotation in the second head, the unloading wheel 21 ' with or without rotation of the article 13 in the unloading wheel 21 ' can transport them.

Preferably, the unloading wheel has 21 the rotatably mounted and controlled by curves article units 22 , where each item unit 22 two opener levers 23 , each a rotatably mounted holding jaw 24 wear, has. Over tie rods 25 can the holding jaws 24 can be stopped by 90 °. This pivoting movement is by a cam-driven pivot lever 26 causes, so that a rotation of the article 13 , which is lockable, however, is effected. Both a pivot axis of the pivot lever 26 as well as a pivot axis for the holding jaws 24 (which is substantially coincident with or parallel to an article transverse axis) therefore extends substantially axially parallel to an axis of rotation of the removal wheel 21 ' ,

Hereinafter, in a further embodiment of the invention, a packaging station 40 with a packing head 41 , a turning station 43 and one instead of the second rotary station 42 in 1a provided folding station 45 explained. First, a subsequent embodiment of the turning station 43 explained.

In 1a are for the packaging of Arti smaller size and with correspondingly smaller turning stops turning stations 43 provided, in which a compensation of the turning-induced shortening of the packaging material is compensated by an axis of rotation of the rotating station inclined to a rotation axis of the associated packing head 41 is arranged so that the associated rotary gripper perform an oscillation (by inclination), ie a movement in the axial direction, due to the rotational movement of the rotating station. However, such a solution is inadequate when large items are wrapped in a twist wrap, e.g. B. in a diameter range between 30 mm and 40 mm, since a much larger axial travel for the rotary gripper in conjunction with the corresponding greater shortening of the packaging material when screwing in the rotary wing is required.

As 12 clarifies, leads the larger design of the turning station 43 with the axially movable and larger space engaging rotary grippers 46 on a front side of a corresponding rotary head 47 also to a change of the packing head 41 such that this with each of the corresponding rotary gripper position associated concave sections 41a (In contrast to the usual circular cylindrical design of an outer peripheral surface of the packing head 41 ) is executed to a sufficient opening and closing movement of rotary gripper jaws 48 the rotary gripper 46 in a collision-free manner.

Returning to the motion control, especially longitudinal motion control of the rotary gripper 46 (of which, for reasons of clarity, in 12a only one on the front end of the turret 47 is shown) rotate these rotary gripper 46 synchronous with corresponding holding jaw pairs 49 of the packing head 41 (of which in 12a also just for reasons of clarity, a pair of holding jaws 49 (pointing upwards), in a conventional manner.

alternative Embodiments of the packing head, z. B. with rotating folding shafts under stamp-supported article transfer between Packing head and upstream station are also possible.

An oscillatory movement of the rotary gripper 46 comes with a drum curve 70 generated in the the turret 47 showing in greater detail 15 is shown, to which reference is made below. In this groove curve 70 are rotating rocker arms 71 provided by the drum curve 70 generated control movement from the fixed drum curve 70 on the axially movable rotary gripper 46 transfer. Preferably, the rotary gripper lead 46 every rotation of the turret 47 a maximum oscillation stroke.

However, this is adjustable, which would be achievable on the one hand by using different drum curves and / or predetermination of the cam engagement position between the cam and cam follower in the circumferential direction, but in the present case in a continuously adjustable manner by an adjustment 75 takes place, by an adjustment of the effective for the Eindrehvorgang stroke by shifting the Oszillations start time relative to a closing time of the rotary gripper jaws 48 the rotary gripper 46 is effected. This is achieved by the drum curve 70 relative to a closing and opening curve 72 is twisted. Prerequisite for this is a gearbox decoupling of axial longitudinal or oscillatory motion of the rotary gripper 46 from the closing and opening movement of the rotary hook jaws 48 , This will be in the turret 47 realized according to this embodiment of the invention in that the closing and Öffnerkurve 72 a toothed segment 73 drives, which is thereby given a reciprocating pivotal movement. With the toothed segment 73 is a spur gear 74 engaged, rotatably on a push rod 76 is stored and rotated in both directions. With the spur gear 74 is a cam sleeve 77 firmly connected, which is against the rocker arm 71 supported. That way, the push rod becomes 76 moved axially and the rotary gripper jaws 48 the rotary gripper are opened and closed. During an oscillatory movement (axial movement) of the rotary gripper 76 slides the spur gear 74 axially in the toothing of the toothed segment 73 , so that the axial movement (oscillation movement) of the rotary gripper 46 from the closing and opening movement of the rotary hook jaws 48 is decoupled.

As already 12a for the packaging station 40 clarifies, is the turning station 43 on the other side of the packing head 41 a folding station 45 to perform such types of wrapping as sachet, top-twist and diagonal letter-folding on one side of the article.

For other types of impact such as double twist, of course, two opposite turning stations 43 can be used or it can on both sides of the packing head in an impact with both sides diagonal letter folding stations 45 be arranged. In the present embodiment, based on the bag folding below the structure of the folding station 45 and a special folding method based on the 13 and 14 explained. In this context is also on 12b noted that a central section of the packaging station 40 in an enlarged view shows, with the turning station 43 and the rotary jaws 48 of the associated rotary gripper 46 on the right side as well as details of the packing head 41 with the holding jaw pairs 49 and further Faltorganen a Faltkopfes 78 in the fold station 45 ,

For a bag folding the article 13 (S. 12b ) in the manner explained above together with the piece of packaging material 5 (S. 14 , in 12b not shown) from the article rapier head 31 in the packing head 41 to hand over. The holding jaws 49 of the packing head 41 enclose the article 13 , where in 12b Packing material not shown tightly placed around the article and in the form of a "U" together with the article 13 is clamped (see. 14 ). This is a starting point for a folding process, as described below with reference to 14 is explained. A starting position for the bag folding explained below is in 14 With " 80 " designated. In the front part of a packing head shaft is the folding station 45 with the folding head 78 Performing the folding operations for a bottom fold (bag bottom). In the rear part of the packing head shaft is the turning station 43 with the turret 47 , which forms a rotary wing at the top of the package and thus completes the packaging process. As shown, the packing head is located 41 in the middle between turret 47 and folding head 78 ,

Referring to 14 but also on 12b and 13 begins a folding process for the folding impact of the bag bottom with a piercing of the packing head center facing projecting surface 1.5 of the U-shaped packaging material section by a pre-folder 79 , whereupon the same folding of the in the same direction of movement folding Fertigfalter (burglars) 81 follows. This is close to the article or on the associated surface of the article 13 on, is very flat and thus able to fill in the area 1.5 completely wipe out the piece of packaging material.

The special feature in this context is that here the same folding step is followed by pre-and Fertigfalter 79 . 81 is executed, wherein the pre-butterfly 79 minimizes material stress, so that an accurate folding by the Fertigfalter (burglar) 81 Even with relatively stiff films and packaging materials can be achieved with relatively strong springback characteristic.

One side of the finished moth 38 in the direction of movement upstream packaging material neck 5.2 is by means of a page moth 82 folded and over the Fertigfalter 81 or burglar 81 placed.

One in the direction of movement (see arrow in 14 ) Downstream packing material salt is then applied to a stationary folding plate as a page folder 83 placed over the previously prepared wrinkles.

In the further course of the rotation of the folding head 78 serves the relatively long in the circumferential direction formed Seitenfalter 83 as a pressure piece for the already produced folds and frontally arranged Packstofflächen. The bottom fold of the bag is through another pre-butterfly 84 and subsequent Finished Butterfly (burglar) 85 completed by placing these over the second mollusk 83 push inwards (pre-folders) or ready-made folds (Fertigfalter 85 ). Again, the pre-butterfly serves 84 the solution and elimination of material tensions and ultimately a clean folding, by the Fertigfalter 85 is completed. Again, a folding step by means of two rectified folding movements is realized, which leads to a particularly high-quality folding or leaves greater latitude in terms of the packaging materials used.

On both sides along a main direction of the article 13 now remaining packaging material bottles 5.3 . 4.5 be through in the packing head 41 stored folding organ interior butterfly 86 and external butterflies 87 created. This is the packaging material 5.3 which is upstream in the direction of movement, by the inner butterfly 86 folded and the downstream in the direction of travel packaging material 4.5 through the outer butterfly 87 on the inside of the butterfly 86 applied packaging material 5.3 pressed.

Thus, a bottom surface and the side surfaces of a bag are completely enclosed by the packaging material. With the help of rotary vane jaws 48 Then the supernatant packaging tube is gripped and completed by forming a rotary wing of the packaging process. Within such a folding or packaging cycle, the greater part of the over a predetermined angular range of rotation of the packing head 41 available for bottom folding, while a smaller and shorter part is used for the formation of the twist stop. By vorerläuterte adjustment of Oszillationszeitpunktes in relation to a closing time of the rotary gripper jaws 48 These time relations can be set and thus an optimization of the packaging process can be achieved, so that a sufficiently large angular range is available for carrying out the more complicated bottom folding, while a relatively small angular range of the packing head rotation serves to close the packaging by means of a twist.

13 shows the folding head 78 again in an individual view, with respect to the movement control of the aforementioned folding organs on an outer cam 88 It should be pointed out that the movement of the first Prefalter 79 controls while the stationary outer cam 89 the Finished Butterfly (burglar) 81 controls. The required for external cam gears kickback forces are by tension springs 90 applied. In addition, a move movement of the lateral butterfly 82 through a groove curve 91 controlled.

For the control of the second prefalter 84 and the second finishing butterfly (burglar) 85 is a first four-bar linkage 92 provided, whose activation by a path of a spatial, stationary groove curve 93 takes place while the second pre-butterfly 84 and the second finished butterfly (burglar) 85 through a second four-bar linkage 94 are supported, whose movement control by another track of the spatial groove curve 93 he follows.

By The invention is for the first time possible, with a continuous working packing machine to realize bag folding and other relatively complicated ones To realize impact forms, in a novel folding process, that a relatively stable packaging U-shape by means of two separately controllable folding organs, a Vorfalter and a finishing moth (burglar) for the folding step, einfaltet, with a corresponding procedure also for a bottom fold is realized. Again, there are two separately controllable Folding organs, namely a second Prefalter and a Fertigfalter (Burglar) for use, whereby occurring folding forces minimized, a popping up of the fold is avoided and a high quality of folding with secure holding of the packaging material is guaranteed.

moreover introduces the new concept for the promotion of packaging items from a singler to a previously unrivaled smoothness of the packaging machine in the intended performance range with extreme product protection.

The Machine concept also makes it possible for the first time the packaging of very large products in the intended performance range in continuous operation.

Finally, it should not go unmentioned that in conjunction with rotary stops and turning stations and heated rotary gripper for sealing of packaging material can be used, as is the subject of EP 1 712 472 A1 is here also to the extent made by express reference to the subject of the disclosure of the present application.

According to the invention leads the modular machine construction in the field of article-carrying packaging equipment, in particular in the area of a removal station or an article gripper station moreover to a high variability regarding possible Impact shapes and article orientations within the packaging machine.
