The present application claim priority to German Application DE 10 2017 203 588.9, filed Mar. 6, 2017, which is incorporated by reference.
The present invention relates to an apparatus with at least two modules that are selectively transferable into an operating position for the particular handling of individual articles or article sets. The present invention furthermore relates to a method for exchanging at least one transport module and at least one work module for a specific operating position.
There is a wide variety of packaging alternatives for processing, assembling, grouping, and packaging articles, such as beverage containers. PET containers are currently the most commonly used type of containers, for instance for beverages, but they are relatively thin-walled and, even when filled, not completely dimensionally stable. For this reason and for the purpose of improved logistic handling, a wide variety of different packages are used for processing and/or packaging grouped individual containers. It is possible to place the containers when they are arranged in a group onto a box blank, for instance, the edges of which are folded upward. It is also possible to use cardboard blanks corresponding in size at least to the base size of an arranged package, on which blanks the individual containers or beverage containers stand, which form a part of a particular package or bundle.
Optionally, these bundle arrangements can be subsequently wrapped in thermoplastic film, which is then applied by a heat shrinking process onto the beverage containers forming a part of a particular bundle, in order to obtain a stable bundle assembly that can be easily transported and stacked. A further packaging variant is referred to as “shrink-only packaging”, because the assembled containers are wrapped in thermoplastic film and the thermoplastic film is subsequently shrunk onto the particular assembled containers without using any other packaging material or any other blanks
In such a package variant, the dimensional stability of the package is ensured solely by the shrinking foil. Currently known packaging machines and their conveying devices are normally specifically optimized to a certain type, size, and/or contour of conveyed goods. Different types of bundles or different packaging alternatives moreover require the use of different, specific conveying devices. In some circumstances, such as changes of products, it is therefore possible that the use of certain conveying devices cannot be continued if these devices are not suited to transporting the specific, currently required type of individual articles or containers. Disturbances in the article transporting process can also occur if the packaging machines are specifically adjusted to transporting a different product variant. Conveying problems such as these may particularly arise when there are changes from packed goods, such as bundle units, to loose goods, such as individual beverage containers or the like. Such articles as beverage containers, which are to be conveyed in a standing position, are prone to toppling over and/or falling down when using conveying devices that are adapted for transporting bundle units, especially if the transport modules are not equipped with conveyor support surfaces that are sufficiently flat and level to safely transport objects with a very small base size.
Apparatuses are already known from prior art that serve to prevent such problems by comprising a plurality of modules, which can be exchangeably or selectively inserted into a specific section of a transport path. Such an apparatus is disclosed in WO 2012/062549 A1, for example. The apparatus described in the document relates to a machine for processing and/or packaging objects, the machine having a substantially horizontal transport path for conveying articles, bundles and/or packaging units. The machine comprises a first horizontal conveying device with at least one transport means for a first operating mode, which horizontal conveying device can be replaced by a further horizontal conveying device with at least one second transport means that is different from the first transport means, in order to establish at least one further operating mode.
Practice has shown that such a process of replacing horizontal conveying devices to adapt the machine to different operating modes requires a certain amount of time that should be kept as short as possible in order to be able to quickly convert such a machine to different operating modes.
One object of the invention can therefore be seen in providing a generic apparatus or a corresponding method, as the case may be, where the apparatus can be converted or adapted to different operating modes in a time-optimized manner. In addition, the apparatus should have a simple structure, and the method should be easy to carry out.
The above objects are fulfilled by an apparatus and a method comprising the features in the independent claims. Further advantageous embodiments of the invention are described in the subclaims.
The invention relates to an apparatus with at least two modules that are selectively transferable into an operating position for the particular handling of individual articles or article sets.
The apparatus comprises at least one transport module that is prepared for moving individual articles or article sets, which are provided for a first packaging type.
The apparatus further comprises at least one work module that is prepared for moving individual articles or article sets, which are provided for a second packaging type that differs from the first packaging type. The at least one work module is moreover able to handle packaging material with which the individual articles or article sets are in contact during the movement. In particular, it can be provided in this context that the at least one work module is formed for erecting flaps of blanks that are formed as packaging material and provided for the individual articles or article sets. The at least one work module can comprise a multitude of circumferentially guided folding fingers for erecting the flaps. The circumferentially guided folding fingers can emerge above a transport level or conveying level formed by the apparatus for the purpose of transporting the individual articles or article sets; and in doing so, the folding fingers can come into contact with a particular flap, as the case may be, and, while emerging, can move the particular flap above the transport level or conveying level into an erect orientation. In particular, the work module can be formed for holding the erected flaps of the blanks formed as packaging material and provided for the individual articles or article sets over a specific period of time during a continuing movement of the particular individual articles or the particular article set. For the circulating movement, the multitude of folding fingers can be mechanically coupled to at least one chain or sealing chain, as the case may be.
It is moreover provided that the apparatus forms a specific operating position and a waiting position, into which specific operating position the at least one transport module or the at least one work module can be selectively inserted, and into which waiting position the at least one transport module is transferable by removing it from the specific operating position. The waiting position can be offset in horizontal and also in vertical direction in relation to the specific operating position. It is thus possible that the at least one transport module is moved in horizontal direction and in vertical direction for being inserted from the waiting position into the specific operating position. Thus, it is conceivable that the at least one transport module is moved in horizontal direction and in vertical direction or is moved in horizontal direction and lifted up in vertical direction, as the case may be, for being transferred from the specific operating position into the waiting position. The waiting position provided for the at least one transport module can therefore be located at a vertically higher level in relation to the specific operating position.
It is furthermore provided that the apparatus comprises at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other, which transmission means is mechanically coupled to the at least one transport module and interacts with the at least one transport module in the specific operating position for the purpose of moving the individual articles or article sets, and which transmission means can flexibly adapt its alignment along its circumferential course in each instance with a change of the at least one transport module from the specific operating position into the waiting position and from the waiting position into the specific operating position. In particular, the at least one transport module can be mechanically coupled via at least one pulley to the at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other. The at least one pulley can be in engagement with the transmission means that is made from a plurality of individual links rotationally movably linked to each other. In this context it is conceivable that the at least one pulley forms gear teeth, via which gear teeth at least one pulley is in engagement with the transmission means that is made from a plurality of individual links rotationally movably linked to each other. Embodiments have proved successful in practice where the at least one transport module comprises at least two pulleys, each of which is in engagement with a common transmission means that is made from a plurality of individual links rotationally movably linked to each other.
In preferred embodiments, the apparatus can comprise a working mechanism, by way of which working mechanism the at least one transport module can be independently removed from the specific operating position and transferred into the waiting position, and it can as well be independently inserted from the waiting position into the specific operating position. As already mentioned above, it is conceivable that the at least one transport module is in each instance moved horizontally and vertically for being transferred into the waiting position as well as for being inserted into the specific operating position. Where required, the working mechanism can for this reason cause a horizontal movement as well as a vertical movement for the at least one transport module.
Alternatively or additionally, it is possible that by way of the working mechanism the at least one work module can be independently transferred from the specific operating position into a further waiting position provided for the second work module, and that by way of the working mechanism the at least one work module can as well be independently inserted from the further waiting position provided for the at least one work module into the specific operating position. In particular, the further waiting position provided for the at least one work module can be positioned below a conveying level or transport level, as the case may be, formed for the individual articles or article sets by the apparatus. In this context it is possible that the at least one work module is independently lowerable by way of the working mechanism below the conveying level or transport level, as the case may be, formed for the individual articles or article sets by the apparatus.
As mentioned, it is possible that the apparatus forms a horizontal movement plane or conveying level and/or transport level, as the case may be, for the individual articles or article sets, with the waiting position, into which the at least one transport module is transferable from the specific operating position, being positioned or disposed, as the case may be, above the horizontal movement plane or conveying level and/or transport level, as the case may be, and/or with a waiting position formed for the at least one work module being positioned or disposed, as the case may be, below the horizontal movement plane or transport level and/or conveying level, as the case may be.
It is also conceivable that at least one transport module comprises a horizontal transport surface and that a multitude of circumferentially guided transport elements is coupled to the at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other. The multitude of circumferentially guided transport elements can be formed for the sliding movement of the individual articles or article sets across the horizontal transport surface of the at least one transport module that is inserted in the specific operating position. The multitude of circumferentially guided transport elements can be formed by a multitude of divider rods, which push the particular individual articles or article sets along the horizontal transport surface. The horizontal transport surface can be formed by a transfer plate being supplied as part of the transport module In particular, at least one pair of transmission means that are each made from a plurality of individual links rotationally movably linked to each other can be provided, with a particular transport element of the multitude of transport elements or with a particular divider rod of the multitude of divider rods, as the case may be, being mechanically coupled to and being moved in a circulating manner via the pair of transmission means that each consist of a plurality of individual links rotationally movably linked to each other.
It is also possible that the at least one transport module comprises at least two guide walls located opposite each other, and that the relative distance of the at least two guide walls located opposite each other can be adapted for the purpose of presetting at least one specific transport lane for the individual articles or article sets, with the transport lane extending along the horizontal transport surface. For the purpose of adapting the relative distance, the at least two guide walls located opposite each other can be coupled to at least one actuator, as the case may be, with the actuator being in contact with a control unit, and with a relative distance of the at least two guide walls located opposite each other being adaptable by way of the actuator and prompted by the control unit.
In various embodiments, it is possible that the waiting position, into which the at least one transport module is transferable form the specific operating position, is formed such that the horizontal transport surface or transfer plate of the at least one transport module, as the case may be, is, when in the waiting position, located above a horizontal conveying level or above a horizontal movement plane and/or horizontal transport level, as the case may be, that is formed for moving the articles or article sets by the apparatus. In addition, the waiting position can be formed such that the multitude of transport elements or divider rods, as the case may be, can move and/or accompany the individual articles or article sets, if applicable, at least in sections along the horizontal conveying level, with the transport elements or divider rods, as the case may be, in contact preferably with the rear ends of the individual articles or article sets.
As already mentioned, the at least one work module that is inserted in the specific operating position can comprise a plurality of circumferentially guided folding fingers, by way of which plurality of circumferentially guided folding fingers flaps belonging to packaging blanks in contact with the individual articles or with the article sets can be erected during the movement of the particular individual articles or article sets.
If applicable, the apparatus can moreover comprise at least one guide member that is preferably formed as deflection member for the at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other, with the at least one guide member that is preferably formed as deflection member being able, for the purpose of acting upon the alignment along the circumferential course of the transmission means that is made from a plurality of individual links rotationally movably linked to each other, to assume at least two different positions that are coordinated to a change of the at least one transport module from the specific operating position into the waiting position and from the waiting position into the specific operating position. It is conceivable in this context that the apparatus comprises at least one actuator, via which the guide member that is preferably formed as deflection member can be moved for the change from a first position into a second position. The first position can be offset in horizontal and/or in vertical direction in relation to the second position. In particular, a first specified position for the waiting position can be assigned to the at least one transport module and a second specified position can be assigned for the specific operating position, with the first specified position and the second specified position, if applicable, being offset in horizontal and/or in vertical direction in relation to each other, and with a movement of the guide member that is preferably formed as deflection member being caused by way of the actuator.
The present invention moreover relates to a method for exchanging at least one transport module and at least one work module for an operating position. Features that have already been described above regarding various embodiments of the apparatus can likewise be provided for various embodiments of the method according to the invention and are therefore not repeatedly mentioned. Features, which will be described below regarding various embodiments of the method, can likewise be used for the previously already described apparatus, where applicable.
It is provided that individual articles or article sets, which are provided for a first packaging type, are moved along the at least one transport module in the operating position. The individual articles can be formed by individual beverage containers. Furthermore, the article sets can be formed by sets of beverage containers. It is furthermore provided that the at least one work module in the operating position moves individual articles or article sets, which are provided for a particular second packaging type that differs from the first packaging type, and which at least one work module in the operating position handles packaging material temporally during the movement of the individual articles or article sets, the packaging material being in contact with the individual articles or article sets. It is thus possible that individual articles or article sets are moved by the at least one work module inserted in the operating position, with the at least one work module inserted in the operating position temporally handling packaging material during the movement of the individual articles or article sets, with which packaging material the individual articles or article sets are in contact while being moved by the at least one work module.
One step of the method provides the at least one transport module inserted in the specific operating position to be removed from the specific operating position, the at least one transport module to be transferred into a waiting position, and the at least one work module to be inserted into the specific operating position.
Temporally thereafter follows a further step, which provides removing the at least one work module that is inserted in the specific operating position from the specific operating position and inserting the at least one transport module that is located in the waiting position into the specific operating position. The at least one transport module and the at least one work module for the specific operating position can thus be exchanged.
For the purpose of moving the individual articles or article sets, it is also provided that the at least one transport module that is inserted in the specific operating position interacts with at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other. The transmission means that is made from a plurality of individual links rotationally movably linked to each other can be formed by at least one chain.
It is additionally provided that, temporally while removing the at least one transport module from the specific operating position and temporally while inserting the at least one transport module from the waiting position into the specific operating position,
a mechanical connection is maintained, the mechanical connection being formed between the at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other and the at least one transport module; and
the at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other flexibly adapts its alignment along its circumferential course.
In the course of or during the flexible adaptation, as the case may be, individual links of the transmission means that is made from a plurality of individual links rotationally movably linked to each other can pivot relative to each other.
In various embodiments it is possible that the at least one transport module that is inserted in the specific operating position is independently removed from the specific operating position and transferred into the waiting position by way of a working mechanism. It is furthermore possible that the at least one work module is independently inserted into the specific operating position by way of the working mechanism. It is, in particular, conceivable that the at least one work module is independently lifted up by way of the working mechanism for being inserted into the specific operating position. It is also possible that the at least one transport module that is inserted in the specific operating position is lifted up from the specific operation position for being transferred into the waiting position.
Additionally or alternatively to this, it is possible that the at least one work module that is inserted in the specific operating position is independently removed by way of a working mechanism from the specific operating position, and that the at least one transport module that is located in the waiting position is independently inserted by way of the working mechanism into the specific operating position. In this context, embodiments have proved particularly successful in which the at least one work module that is inserted in the specific operating position is lowered downward by way of the working mechanism for the purpose of being removed, and is transferred into a waiting position provided for the at least one work module. It is also possible that the at least one transport module located in the waiting position is lowered downward for being inserted into the specific operating position.
It is thus possible that at least one transport module that is inserted in the specific operating position is lifted upward while being removed from the specific operating position and in this context passes on into the waiting position, the waiting position being disposed above a horizontal movement plane formed for the individual articles or article sets. It is thus also possible that the at least one work module that is inserted in the specific operating position is lowered downward while being removed from the specific operating position and in this context passes on into a waiting position provided for the at least one work module, with the waiting position provided for the at least one work module being disposed below a horizontal movement plane formed for the individual articles or article sets.
In preferred embodiments, the transmission means that is made from a plurality of individual links rotationally movably linked to each other can circumferentially drive a multitude of transport elements, the multitude of transport elements moving the individual articles or article sets, in a sliding manner and preferably in each instance in contact with the rear ends of the individual articles or article sets, across a horizontal transport surface or across a horizontal transfer plate, as the case may be, that is formed as a part of the at least one transport module that is inserted in the specific operating position.
It is furthermore possible that the at least one specific transport module is removed from the specific operating position and is transferred into the waiting position, and in this context, temporally after transfer of the at least one transport module into the waiting position, the multitude of transport elements moves individual articles or article sets along a horizontal movement plane or along a horizontal conveying level, as the case may be, with the transport elements in contact preferably with the rear ends of the individual articles or article sets, and/or the multitude of transport elements accompanies individual articles or article sets along a horizontal conveying level, with the transport elements in contact preferably with the rear ends of the individual articles or article sets. In practice, embodiments have proved successful for this purpose in which the at least one work module that is inserted in the specific operating position is disposed immediately upstream of an infeed, and the multitude of transport elements moves the individual articles or article sets along the infeed, with the transport elements in contact preferably with the rear ends of the individual articles or article sets. Immediately before and/or while the individual articles or article sets pass over from the infeed onto the at least one work module that is inserted in the specific operating position, individual transport elements of the multitude of transport elements can lose their contact to the particular individual article or to the particular article set. Via the at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other, the individual transport elements of the multitude of transport elements can in this context be upwardly removed or guided away, as the case may be, from the particular individual article or from the particular article set, as the case may be.
In addition, the at least one work module that is inserted in the specific operating position can, by way of a plurality of circumferentially guided folding fingers, erect flaps belonging to packaging blanks in contact with the individual articles or with the article sets, and can move the individual articles or article sets by way of the circumferentially guided folding fingers while the flaps are being erected. In this context it is conceivable that, during the movement by way of the plurality of circumferentially guided folding fingers, the individual articles or article sets are at least temporarily accompanied by a particular transport element, which is in contact preferably with the rear ends of the individual articles or article sets.
In various embodiments of the method, a guide member that is preferably formed as deflection member for the at least one transmission means that is made from a plurality of individual links rotationally movably linked to each other can be furthermore provided, with a position of the at least one guide member that is preferably formed as deflection member being in each instance adjusted in the context of a change of the at least one transport module from the specific operating position into the waiting position and from the waiting position into the specific operating position, for the purpose of acting upon the alignment along the circumferential course of the transmission means that is made from a plurality of individual links rotationally movably linked to each other. For the purpose of the adjustment, the guide member that is preferably formed as deflection member can be moved in vertical direction and/or in horizontal direction.
In the following passages, the attached figures further illustrate exemplary embodiments of the invention and their advantages. The size ratios of the individual elements in the figures do not necessarily reflect the real size ratios. It is to be understood that in some instances various aspects of the invention may be shown exaggerated or enlarged in relation to other elements to facilitate an understanding of the invention.
The same or equivalent elements of the invention are designated using identical reference characters. Furthermore and for the sake of clarity, only the reference characters relevant for describing the individual figures are provided. It should be understood that the detailed description and specific examples, while indicating a preferred embodiment, are intended for purposes of illustration only and are not intended to limit the scope of the invention. It should also be noted that the features described below in connection with the
The apparatus 1 comprises a work module 5, which is located in an operating position BL in
Two transmission means 8 oriented parallel to each other and each made from a plurality of individual links rotationally movably linked to each other take the form of a chain 9. A multitude of divider rods 13 is mechanically coupled to the transmission means 8 or chains 9, as the case may be, the divider rods 13 being circumferentially moved via the transmission means 8 or chains 9, as the case may be. In the area of an infeed 12, the divider rods 13 in this context come into surface contact with the rear end of a particular set of beverage containers and then push the particular set of beverage containers across the slide plate 15 toward the work module 5, which is in the operating position BL. When a particular set of beverage containers passes over from the slide plate 15 onto the work module 5, the particular divider rod 13 leaves the particular set of beverage containers in an upward direction. When passing over from the slide plate 15 onto the work module 5, the particular set of beverage containers furthermore moves onto a particular blank of packaging material, which is formed as tray in the instance of the work module 5 that is in the operating position BL. As already mentioned above, the blank of packaging material has front and back flaps that are folded upward during a continuous or uninterrupted transport, as the case may be, of the particular set of beverage containers standing upon the blank of packaging material or on the tray, as the case may be, by way of a multitude of folding fingers 7 (cf.
For the sake of completeness, it should be noted that it is not imperative for the divider rods 13 to leave a particular set of beverage containers when it passes over from the slide plate 15 onto the work module 5. It is also conceivable that the divider rods 13 continue to accompany the sets of beverage containers after they have passed over onto the work module 5 or, as the case may be, that the divider rods 13 continue to remain in contact with the rear end of at least one beverage container of a particular set, where applicable. At the same time, erected front and back flaps of a blank of packaging material assigned to a particular set of beverage containers can be held in an erect orientation by way of the folding fingers 7.
A transport module that is exemplarily designated with the reference character 3 is moreover part of the apparatus 1. The transmission means 8 made from a plurality of individual links rotationally movably linked to each other or the chain 9, as the case may be, is mechanically coupled to the transport module 3. Furthermore, the transport module 3 in
A further waiting position W2 is also indicated, which further waiting position W2 is below a transport level or conveying level, as the case may be, formed for the sets of beverage containers. In the further waiting position W2, the work module 5 can change from the specific operating position BL according to
The transmission means 8 that is made from a plurality of individual links rotationally movably linked to each other or the chain 9, as the case may be, is thus mechanically coupled to the transport module 3, which mechanical coupling is formed both in the waiting position W1 and in the operating position BL, and continues to remain formed during the transfer of the transport module 3 from the waiting position W1 into the specific operating position BL and vice versa.
The plurality of circumferentially guided folding fingers 7 formed as part of the work module 5 is now discernible in
In each instance of passing over from the infeed 12 or from the slide plate 15 onto the work module 5, a particular set of articles or of beverage containers, as the case may be, moves onto a particular blank. Each set of beverage containers is pushed with their rear ends in contact with a particular divider rod 13 (cf.
From the presentation in
The guide member 22 or the deflection member 24, as the case may be, as exemplarily illustrated in
The slide plate 15 across which the sets of beverage containers are moved via the divider rods 13 at least approximately immediately follows the transfer plate 20 of the transport module 3 that is inserted in the specific operating position BL. Hereby, sets of beverage containers can pass over from the infeed 12 or from the slide plate 15, as the case may be, onto the work module 5 or onto the transfer plate 20, as the case may be, without unwanted tipping over in the process. By the divider rods 13 that are coupled to the transmission means 8 or to the chains 9, as the case may be, the sets of beverage containers are placed from the slide plate 15 onto the transfer plate 20 and then are moved in transport direction TR along the transport module 3 between the guide walls 26 that are located opposite each other
If the transport module 3 is in the specific operating position BL or if the transport module 3 has been inserted into the specific operating position BL, as the case may be, no blanks formed as packaging material will be introduced into a transport path of the sets of beverage containers between the infeed 12 or the slide plate 15, as the case may be, and the transport module 3 or the transfer plate 20, as the case may be. The sets of beverage containers are moved by the divider rods 13 along the transport module 3 or along the transfer plate 20, as the case may be, without in this context being in contact with a blank of packaging material or without in this context standing on a blank of packaging material, as the case may be. If the transport module 3 is in the specific operating position BL or if the transport module 3 is inserted in the specific operating position BL, as the case may be, it is provided that the sets of beverage containers leave the transfer plate 20 or lose their contact to the transfer plate 20 and in this context move onto a blank that takes the form of packaging material. The blank that takes the form of packaging material can be a pad that provides a standing surface for a particular set of beverage containers and that has no flaps being prepared for transfer into an erect orientation.
The invention has been described with reference to a preferred embodiment. Those skilled in the art will appreciate that numerous changes and modifications can be made to the preferred embodiments of the invention and that such changes and modifications can be made without departing from the spirit of the invention. It is therefore intended that the appended claims cover all such equivalent variations as fall within the true spirit and scope of the invention.
