Description

Device for the production of packaging with an independent

Dornradantrieb

The invention relates to a device for the production of packaging, in particular for the processing of packing coats, comprising: a mandrel wheel with a mandrel wheel shaft having a central axis, a plurality of mandrels fixed to the mandrel wheel shaft, the mandrels forming at least one mandrel group whose mandrels are in a plane perpendicular to the central axis the mandrel wheel shaft are arranged, at least a first arranged on the mandrel wheel machining station with a drive, and a mandrel wheel for driving the mandrel wheel shaft.

Such devices are often used as part of a filling machine and also referred to as "mandrel group".

Packaging can be done in different ways and in different ways

Materials are produced. A widespread possibility of their production is to produce a blank from the packaging material, from which by folding and further steps first a packing jacket and finally a packaging is formed. This production method has the advantage, among other things, that the blanks are very flat and can thus be stacked to save space. In this way, the blanks or packing coats can be made at a different location than the folding and filling of the packaging coats done. As a material composites are often used, for example, a composite of several thin layers of paper, cardboard, plastic or metal, especially aluminum. Such packaging is widely used, especially in the food industry.

In the field of packaging technology, numerous devices and methods are known, with which flat folded packaging coats unfolded, one-sided closed, filled with contents and then completely closed.

A special challenge is the closing of the packaging coats, because the closure requires a reliable sealing of the packaging coats, which also has to be done for the subsequent transport and others

Withstand loads. The sealing is often done in several

Steps: First, the package jacket is heated ("activated") in the area to be sealed, then the opposite sides of the package jacket are pressed together in the area to be sealed

The cohesion between the compressed areas is achieved, for example, by providing an internal plastic layer, which becomes viscous when heated and thus in the subsequent

Pressing forms a bond. This process is also referred to as "sealing".

For processing, in particular for closing the underside of the packing shells, so-called "mandrel wheels" are frequently used, on whose radially protruding mandrels the still unfilled packing shells are slid in. The cross section of the mandrels approximately corresponds to the cross section of the packages to be produced, so that the packing shells are already pushed open on the spines the desired

Take cross-sectional shape.

While the packing jacket is located on the mandrel, the processing of the packing jacket takes place cyclically in the region of the protruding end of the mandrel. On the one hand, this has the advantage that the packing shells can be successively changed by different tools at different speeds by a rotation of the mandrel wheel

Processing stations can be edited. For example, heating can take place in a first mandrel wheel position and, subsequently, compression can take place in a second mandrel wheel position. Another advantage of machining the packing shells on a mandrel wheel is that the shape of the projecting ends of the mandrels can be adapted to the shape of the underside of the packages to be produced, so that the ends of the mandrels in the

Pressing can serve as an abutment. A challenge in the use of mandrel wheels lies in the drive of the mandrel wheel and in the drive arranged on the mandrel wheel

Processing stations. One difficulty is that the processing of the packing shells at the different processing stations must be precisely timed to the cyclic movement of the mandrel wheel.

In order to achieve the required synchronicity, it has already been proposed to use the same drive for driving the mandrel wheel and for the processing stations arranged thereon. The drive power is in this case

for example, distributed over a toothed belt on different pulleys and forwarded from there to the respective processing station.

This principle is comparable to the function of a toothed belt or a timing chain in an internal combustion engine with multiple camshafts, there also the rotational position of the camshaft - and thus the position of the intake and

Exhaust valves - exactly on the position of the crankshaft - and thus the position of the piston - must be coordinated. For exact compliance with the control times, no change in the angular position of the camshaft and crankshaft may occur. This is achieved in that the crankshaft and all camshafts are positively connected to each other via a toothed belt.

In addition to synchronicity is a common drive also for the sake of

Compactness and cost reasons used. Here, too, there is an example from the field of internal combustion engines, where several consumers are driven by the same V-belt from the crankshaft and thus have the same drive. For example, consumers can be a generator ("Alternator"), a water pump, a hydraulic pump or the like.

There are therefore numerous reasons why the machining stations and the mandrel wheel share the same drive in many mandrel wheels used in practice. Such, known from the prior art drive concept is shown in Fig. 1 in a schematic representation.

However, such a drive concept, in addition to the advantages mentioned but also disadvantages. A first disadvantage is that the mechanical connection of all processing stations with the same drive is structurally complex and requires a large number of transmission elements (toothed belts, pulleys, drive shafts, cams, etc.). Another disadvantage is the difficult maintenance. For as soon as a defect occurs at a processing station and this processing station has to be decoupled from the drive (for example by removing the toothed belt), all reconnected (for example by mounting the toothed belt) all the coupled processing stations in their

Rotary position can be precisely coordinated. In short, an intervention in the drive of a processing station has the consequence that the entire drive system must be readjusted. In addition, with every small change the

Package size or packaging geometry a new cam for driving the individual components can be calculated, manufactured, assembled and adjusted. The invention is therefore based on the object described at the outset

To design and develop device such that the mechanical complexity of the device is reduced and that the device can be easily maintained. This object is achieved in a device according to the preamble of claim 1, characterized in that the mandrel wheel is mechanically decoupled from the drive of at least one processing station. It is a device for the production of packaging, in particular for the processing of packing coats. In particular, this may be

Trade packaging or packaging coats for foodstuffs, wherein the

Packaging or packaging coats are preferably made of a composite material of several thin layers of paper, cardboard, plastic or metal, in particular aluminum. The device initially comprises a mandrel wheel with a mandrel wheel shaft with a central axis. The mandrel wheel shaft is preferably cylindrical in shape and the central axis extends in the longitudinal direction - ie in the axial direction - centrally through the mandrel wheel shaft. The mandrel wheel shaft may be made of metal, for example. The mandrel wheel also includes a plurality of mandrels attached to the mandrel wheel shaft. The attachment serves the purpose that the mandrels also rotate about the central axis of the mandrel wheel shaft upon rotation of the mandrel wheel shaft about its central axis. However, it may be a releasable attachment to exchange the mandrels can. The cross-sectional area of the mandrels can be rectangular, in particular square. The mandrels form at least one mandrel group whose mandrels are arranged in a plane perpendicular to the central axis of the mandrel wheel shaft. The arrangement in a plane serves the purpose that the mandrels of the same group of mandrels can be successively brought by a rotation of the mandrel wheel shaft in the same positions, there to edit the

Packing coats to enable by different stationary tools.

Furthermore, the device comprises at least one first on the mandrel wheel

arranged processing station with a drive, and a mandrel wheel for driving the mandrel wheel shaft. The drive may be, for example, an electric motor. The processing station can be, for example, a pusher, a heating unit, a folding unit (eg longitudinal folder, transverse folder), a press or a puller. According to the invention, it is provided that the mandrel wheel drive is mechanically decoupled from the drive of the at least one processing station. Mechanical decoupling is understood in particular to mean that the two drives are not mechanically connected to one another. The goal of the mechanical

Decoupling is, for example, in the two drives in terms of all

Drive parameters (speed, direction of rotation, etc.) to operate individually. An effect of the mechanical decoupling lies in the fact that a defective drive at the mandrel wheel can be exchanged, without this the drive of the

Processing station is affected. The processing station may be a pusher, a heating unit, a folding unit (e.g., longitudinal folder, cross folder), a press, or a puller. In practical experiments, however, it has been found that a mechanical decoupling of the mandrel wheel drive from the press ("floor press") and from the folding unit (in particular the longitudinal folder) brings about particular advantages

Processing stations particularly high dynamic forces are required

(Press / longitudinal folder) or that at these processing stations particularly complex movements are required timed precisely coordinated (longitudinal folder). Both can be solved well with separate drives tailored to the respective requirements.

A development of the device is characterized by a second arranged on the mandrel wheel processing station with a drive. In this case it can be provided that the mandrel wheel drive is mechanically decoupled from the two drives of the at least two processing stations. At the second

Processing station can be a pusher, a heating unit, a

Folding unit (eg longitudinal folder, Querfalter), a press or a puller act, if they are not already provided as the first processing station. The terms "first" and "second" processing station are for convenience only and do not indicate the order of processing. The idea is therefore to decouple the mandrel wheel not only from the drive of a processing station, but also the mandrel wheel drive from the drive of a second Decouple processing station, provided that at least two processing stations are provided. Preferably, the drive of the first processing station and the drive of the second processing station are mechanically decoupled from each other.

The device can be supplemented according to a further embodiment by a third arranged on the mandrel wheel processing station with a drive. In this case it can be provided that the mandrel wheel drive is mechanically decoupled from the three drives of the at least three processing stations. The third processing station can also be a pusher, a heating unit, a folding unit (for example, longitudinal folder, transverse folder), a press or a puller, if these are not already provided as the first or second processing station. The terms "first", "second" and "third" processing stations are for the purpose of distinction only and do not indicate the order of processing, so the idea is to decouple the mandrel wheel drive not only from the drive of the first two processing station, but the In addition, the drive of the first processing station, the drive of the second processing station and the drive of the third processing station are mechanically decoupled from one another.

After a further embodiment of the device is provided that the

Mandrel drive is mechanically decoupled from the drives of all processing stations. This training is based on the idea to decouple the mandrel wheel drive from the drive of all processing station - regardless of how many processing stations are provided. Preferably, the drives of all processing stations are mechanically decoupled from each other.

A further embodiment of the device provides that one of

Processing stations is a press, in particular a ground press for pressing the bottom surfaces of the packaging coats. The press is pressed on the floor press the end portions of the packing shells to form a bottom. This processing step requires high forces and decides whether the

Packaging is tight in the area of its bottom. Against this background, the mechanical decoupling of the drive of the press from the mandrel wheel drive has the advantage that the drive of the press specifically with regard to the mentioned

Requirements can be selected and set. In addition, it can be better responded to by separate drives on the fact that the press to a

Time is pressed onto the bottom of the package, where the mandrel wheel is stationary. This can be implemented only with difficulty with mechanically coupled drives. Mechanical decoupling eliminates the need for additional mechanical components (e.g., a timing belt or cam) which can result in less wear, friction, backlash, and elasticity. This increases the positioning accuracy of the soil press relative to the respective (currently) associated mandrel. The positioning accuracy is decisive for the tightness of the floor and thus for the quality of the packaging.

According to a further embodiment of the device, it is provided that one of the processing stations is a folding device, in particular a longitudinal folder or a transverse folder for folding the bottom surfaces of the packing shells. At the

Folding means, the folding of the end portions of the packing shells takes place.

In particular, it can be a longitudinal folder (folding movement in the circumferential direction of the mandrel wheel) or a transverse folder (folding movement in the direction of the central axis of the mandrel wheel). During the folding of the package mantle, particularly complex movements have to be precisely timed coordinated. The mechanical decoupling of the drive of the folding device from the mandrel wheel drive has the advantage that the drive of the folding device can be selected and adjusted specifically with regard to the requirements mentioned. In addition, it can be better responded to by separate drives on the fact that the folding to a

Time takes place in which the mandrel wheel is stationary. This can be implemented only with difficulty with mechanically coupled drives. Again, by a mechanical decoupling on additional mechanical components (eg a Timing belt) are omitted, which less wear, friction, play and elasticity can be achieved. This increases the positioning accuracy of the folding device relative to the respective (currently) associated mandrel. The positioning accuracy is decisive for the tightness of the floor and thus for the quality of the packaging. In addition, when changing the

Packing size or packaging geometry, the movement of the Längsfalters be easily adjusted via the controller, in particular via the engine control; a change of the cam is not required.

In a further embodiment of the device is provided that one of

Processing stations is a slide for pushing the packing shells on one of the mandrels. Alternatively or additionally, it can be provided that one of the processing stations is a puller for removing the packing shells from one of the mandrels. Also the pushing on and off of the packing coats can only take place when the mandrel wheel is stationary. Such as-asynchronous motion can only be implemented with great difficulty using mechanically coupled drives. Another advantage of a mechanically decoupled drive is that due to the elimination of some mechanical components, the accessibility or the accessibility of the

Sliders / pullers is improved. This is especially helpful when servicing or checking the activation image or when removing a faulty or jammed packaging. Improved accessibility and accessibility also reduce the risk of injury due, for example, to proximity to hot components (eg floor heating). According to a further embodiment of the device, it is provided that the mandrel wheel comprises at least two, in particular at least four mandrel groups. According to a further embodiment of the device, it is provided that each mandrel group comprises at least four mandrels, in particular at least six mandrels. By having a larger number of mandrel groups, multiple lines of packaging can be processed simultaneously. By a larger number of thorns per Mandrel group can take a larger number of processing steps on the

Packungsmänteln be performed.

A further embodiment of the device provides that a drive unit is used as Dornradantrieb comprising an electric motor and a transmission. Alternatively, it can be provided that a direct drive is used as Dornradantrieb. Alternatively or additionally, it may be provided that a drive unit which comprises an electric motor and a transmission is used as the drive of at least one processing station. Alternatively, it can be provided that a direct drive is used as the drive of at least one processing station.

High demands are placed on the drives used. In particular, the drives must be suitable to take a certain rotational position at a predetermined time and to comply with this rotational position very accurately even under load. Compliance with certain angular positions is achieved in mechanically coupled drives, for example by a toothed belt. Experiments have shown that especially drives with a low backlash and high torsional rigidity are suitable. Preferably, the drive unit or the direct drive together with the driven therefrom mandrel or together with the driven thereof

Processing station a torsional rigidity of> 450 Nm / arcmin, of> 500

Nm / arcmin, of> 550 Nm / arcmin, of> 600 Nm / arcmin or of> 650 Nm / arcmin. The torsional rigidity therefore does not relate to the drive unit or the direct drive alone; it refers instead to the particular system

Drive unit or direct drive and driven component thereof.

Preferably, the drive unit or the direct drive together with the driven therefrom mandrel or together with the driven thereof

Machining station a torsional backlash <5 arcmin, <3 arcmin or <1 arcmin. Particularly preferred is a torsional backlash of 0 arcmin (backlash-free). The Torsional stiffness does not refer to the drive unit or the

Direct drive alone; Instead, it refers to the respective system of drive unit or direct drive and component driven by it. Preferably, the drive unit or the direct drive, together with the mandrel wheel driven therefrom or together with the processing station driven therefrom, has a tilting rigidity of> 850 Nm / arcmin, of> 1000

Nm / arcmin, of> 1200 Nm / arcmin or of> 1300 Nm / arcmin. The

Tilting stiffness therefore does not relate to the drive unit or the direct drive alone; Instead, it refers to the respective system of drive unit or direct drive and component driven by it. By a sufficiently high tilting stiffness between the engine and the component connected to a wobbling motion is avoided. Instead of a unit of electric motor and (preferably backlash-free) gear can also be a direct drive -also an electric motor without a separate gear - are used, for example, a hollow shaft direct drive. Alternatively, a torque motor without gear can be used as a direct drive.

Direct drives are characterized by the property of being able to be mounted directly on the shaft of the component to be driven, that is to say without an intermediate gearbox. The absence of a transmission has the advantage of a compact, low-backlash or even backlash-free design.

In the known from the prior art - mechanically coupled - design, the position control of the electric motor designed difficult because the

Mass moment of inertia of the system to be driven is not constant, but is time variable. For example, this is due to the superposition of several complex dynamic processes with nonuniformly translated mechanisms. In a proposed here - mechanically decoupled - construction, the

Position control of the electric motor, however, by a torque feedforward that is, by specifying the moments of inertia resulting from the calculation. Specifically, it is proposed that the device or its drive has a control in which at least one time profile of a moment of inertia is stored. Each drive can have its own controller; On the other hand, it is also possible to provide a common control for a plurality of drives.

So far one feared so-called lag errors, which in the course of the

Production period cause a deterioration of the synchrony. To avoid this, it can be provided that the moving masses - preferably on their return movement from the working position - pass through a reference point. In this way, occurring deviations can be compensated. By a

Feedforward control of the speed and / or torque, such lag errors can also be avoided.

The invention will now be described with reference to a preferred one

Fig. 1 shows a known from the prior art device 1 for the production of packaging with a mandrel wheel 2 in a schematic representation. First, flat blanks 3 are introduced into a magazine 4 and then unfolded in a Auffalteinrichtung 5 to Packungsmänteln 6. The device 1 comprises a mandrel wheel 2 with a mandrel wheel shaft 7 with a central axis 8. Six mandrels 9 are fastened to the mandrel wheel shaft 7. The six mandrels 9 shown in FIG. 1 form one Mandrel group whose mandrels 9 in a plane perpendicular to the central axis 8 of the

Mandrel wheel 7 are arranged. The mandrel 2 can cyclically against the

Clockwise (shown by an arrow) are moved and stopped in six different mandrel wheel positions I-VI. In the mandrel wheel positions I-V, a processing station B1-B5 is arranged in each case before the end of the mandrels 9, at which the packing jackets 6 are to be processed in their end regions 10, for example in their bottom regions.

The device 1 shown in Fig. 1 also has a mandrel wheel 11 for

Drive the mandrel wheel 7 on. The mandrel wheel drive 11 is mechanically coupled to the mandrel wheel shaft 7, for example via a toothed belt 12

Mandrel drive 11 drives not only the mandrel wheel shaft 7, but he also drives the processing stations B1-B5. For this purpose, the mandrel wheel drive 11 is mechanically coupled to each of the processing stations B1-B5, for example via (only schematically illustrated in FIG. 1) toothed belt 12 and / or other suitable ones

Coupling elements such as shafts, gears and the like.

2, a device according to the invention for the production of packages with a mandrel wheel 2 is shown in a schematic representation. Those areas of the device which have already been described in connection with FIG. 1 are provided with corresponding reference numerals in FIG. An essential difference to the device 1 (FIG. 1) known from the prior art is that the device 1 'according to the invention has a different drive concept.

In particular, it is provided in the device shown in FIG. 2 that each

Processing station Bl-Bl has its own drive AI to A5 and that the

Mandrel drive 11 is mechanically decoupled from those of the drives A1-A5 all processing stations Bl- B5.

Based on the device 1 shown in FIG. 2, the production of a (unilaterally open) packaging is to be shown by way of example. First, the already unfolded packing shells 6 from the first processing station, in which it is To a slider Bl is, taken from the Auffalteinrichtung 5 and pushed onto that mandrel 9, which is located in the mandrel wheel position I. The pusher Bl is for this purpose driven by its own drive AI, which is mechanically decoupled from the mandrel wheel drive 11 (and the other drives A2, A3, A4, A5).

Thereafter, the mandrel 2 of the mandrel wheel position I in the

Mandrel wheel position II turned. The mandrel wheel shaft 7 of the mandrel wheel 2 is for this purpose driven by the mandrel wheel drive 11, which is mechanically decoupled mechanically from the drives A1-A5 of all processing stations B1-B5.

In the second mandrel wheel position II, the packing shells 6 from the second processing station, which is a heating unit B2, in their

End areas 10 heated. The heating unit B2 is for this purpose moved by its own drive A2, which is mechanically decoupled from the mandrel wheel drive 11 (and the other drives AI, A3, A4, A5).

Subsequently, the mandrel wheel 2 is rotated by the mandrel wheel position II in the mandrel wheel position III. The mandrel wheel shaft 7 of the mandrel wheel 2 is in turn driven by the mandrel wheel drive 11, which is mechanically decoupled mechanically from the drives A1-A5 of all processing stations B1-B5.

In the third mandrel wheel position III, the folding of the end regions 10 of FIG

Packing jackets 6 through the third processing station, which is a folding unit B3. In particular, it may be a longitudinal folder

(Faltbewegung in the circumferential direction of the mandrel 2) or a Querfalter (folding movement in the direction of the central axis 8 of the mandrel 2) act. For this purpose, the folding unit B3 is moved by its own drive A3, which is mechanically decoupled from the mandrel wheel drive 11 (and the other drives AI, A2, A4, A5). Thereafter, the mandrel 2 of the mandrel wheel position III in the

Mandrel wheel position IV turned. The mandrel wheel shaft 7 of the mandrel wheel 2 is this

in turn driven by the mandrel wheel drive 11, the mechanical of the

Drives A1-A5 of all processing stations B1-B5 is mechanically decoupled.

In the fourth mandrel wheel position IV, the end regions 10 of the packing jackets 6 are pressed by the fourth processing station, which is a press B4, which is also referred to as a "bottom press." For this purpose, the press B4 is moved by its own drive A4. which is mechanically decoupled from the mandrel wheel drive 11 (and the other drives AI, A2, A3, A5).

Subsequently, the mandrel wheel 2 is rotated by the mandrel wheel position IV in the mandrel wheel position V. The mandrel wheel shaft 7 of the mandrel wheel 2 is in turn of the

Mandrel drive 11 driven mechanically mechanically decoupled from the drives A1-A5 all processing stations B1-B5.

In the fifth mandrel wheel position V, the packing shells 6 are withdrawn from the mandrel 9 by the fifth processing station, which is a puller B5, for further, no longer on, the device

Processing steps to be supplied. The puller B5 is for this purpose moved by its own drive A5, which is mechanically decoupled from the mandrel wheel drive 11 (and the other drives AI, A2, A3, A4).

After the packing shells 6 have passed through the processing stations B1 to B6, the packing shells 6 are closed on one side (eg in the region of the bottom) and can be filled in subsequent work steps and closed off from the other side (eg in the region of the gable). LIST OF REFERENCE NUMBERS
