EP3147115B1 - Machine and method for the production of a cup - Google Patents

Description

The invention relates to a machine for producing a cup of composite material, namely an outer shell and an inner cup, and a method for producing such a cup, as described in claims 1 and 13.

The EP 1 990 184 A1 describes a device for producing a conical sleeve for cups and / or a conical paper cup. Here, the device comprises a machine frame and at least two rotatably connected to the machine frame and cyclically driven star wheels, a first star wheel having a plurality of conical mandrels, on each of which a sleeve of a flat blank is malleable. The star wheels are arranged lying in a plane and arranged on horizontally oriented drive shafts on a vertical wall of the machine frame. In this case, in the region of the first Stemrades the shape of the sleeve, starting from a planar blank. Thus, flat blanks are fed to a first processing station, this being done by a separating device, starting from a blank stack. The flat blank is wound in the subsequent processing stations around the conical mandrel, sealed on its longitudinal side and then forms a conical sleeve. In the area of a transfer station, the finished sleeve is transferred to a hollow mandrel of the second star wheel. This hollow mandrel receives the sleeve from the outside. At the moment of transfer, the hollow mandrel in the processing station is aligned exactly coaxially with the conical mandrel of the processing station in the region of the first starwheel. Thus, the sleeve can be transferred in a linear motion directly from the first star wheel to the second star wheel. In the area of the second star wheel, after the transfer of the sleeve from a third star wheel, a prefabricated paper cup or a prefabricated plastic cup is fed and inserted into the sleeve located in the hollow mandrel. In a subsequent processing station, the inner cup inserted into the sleeve is connected to the sleeve in a separate step. This can be done for example by pressing or gluing. After this connection process, the finished cup can be removed.

From the DE 195 17 394 A1 For example, a method and a machine for producing a thermally insulated cup container having a corrugated outer shell and a having an inner cup, which are separately molded and assembled. The outer jacket is first processed from a smooth blank to a smooth and frusto-conical blank and then corrugated. In a machine for making cup containers, the embossing of the outer shell and the assembly of the same with the inner cup can take place in one and the same shaped bushing, of which a plurality are arranged on a rotary star. In this case, an adhesive is applied in the region of a preparation station on the blank and then transferred to the mandrel, which is arranged on a rotary star. The application of the adhesive takes place with a wheel-shaped gluing unit, wherein the application takes place in a parallel direction with respect to the conveying direction of the respective blank. After forming the sleeve, the transfer is made to a hollow shape of another rotary star, in which the embossing of the outer shell takes place. In a next station glue is applied to insert the inner cup in the next prepared workstation in the thus prepared and already formed sleeve. In a subsequent fixing and cooling station, the final connection between the inner cup and the corrugated outer shell takes place. In the last station, the removal of the finished container takes place.

The US 6,663,926 B1 describes a heat-insulating container comprising a cup-shaped inner container and a surrounding conical outer shell. In this case, the feeds of the blanks via its own feeding device, which is formed of parallel juxtaposed conveyor belts with driver elements. In this preparation station, the adhesive is applied by means of an adhesive applicator roll on one end of the blank. Again, the application of the adhesive takes place in parallel direction with respect to the conveying direction of the respective blank. This prepared blank is transferred to a star wheel with a vertically oriented axis of rotation. On the star wheel frustoconical mandrels are arranged, on which the shaping of the blank takes place towards the shell. The shell is shaped by means of pincer-like gripping arms which wind the flat blank around the frustum-shaped mandrel and thus form the shell or a cuff.

Disposable cups are nowadays indispensable, usually to transport liquid, pasty or even powdery substances from a production site or delivery point to the consumer and to enable the latter to consume the cup contents. When Production facilities include, for example, manufacturers of yoghurt, ready meals and beverages. As dispensaries, for example, restaurants, food stalls or coffee houses are conceivable that pass the cup content usually unlocked or unsealed.

The Fig. 1 shows a per se known cup 100 made of composite material, namely an outer shell 101, in which an inner cup 102 is arranged. In this case, it is also possible to speak of a combination packaging container, since preferably the inner cup 102 and the outer shell 101 formed from a blank or a development are formed from mutually different materials. Such cups 100 further have an open and a closed end region, wherein usually a cross-sectional dimension in the open end region is greater than that in the closed end region. The open end region also usually has a flange-shaped edge strip, which can be connected to a closure device, in particular sealed. Also, arbitrary cross-sectional shapes can be used, which may also be designed differently from one another.

In principle, there are several methods to make this cup 100. One possibility is to wrap the outer shell 101 around the finished inner cup 102. In this case, the inner cup 102 is usually received by a mandrel, which takes over the support and support during the winding process.

Another possibility is to produce inner cup 102 and outer shell 101 independently of each other and then push them into each other. The inner cup 102 has for this purpose in the bottom region usually a bead on the sliding down of the outer shell 101 of the conical or tapered tapered inner cup 102 prevents if it is not or only slightly glued to the inner cup 102.

Another possibility is that the outer shell 101 is first produced from the blank or the unwinding and this is inserted before the manufacturing process of the inner cup 102 in the intended for this molding process mold cavity of the mold. The production of the inner cup 102 is made for cost reasons preferably in a deep-drawing process starting from a film-like layer of a thermoformable material.

The present invention relates to that manufacturing variant in which a finished outer shell 101 and a finished inner cup 102 are pushed into each other.

The inner cup 102 and the outer shell 101 are usually made of different materials. For example, the inner cup 102 is often made of plastic or other thermoformable material and the outer shell 101 of paper or cardboard. These can still be printed before the assembly or forming the outer shell of the settlement or the blank. It is also conceivable, for example, that the inner cup 102 is made of foiled cardboard. Furthermore, the outer shell 101 may also be made of plastic, in particular of foamed plastic. In addition, the outer shell 101 may be configured not only in the form of a cuff but also in the shape of a cup. In this case, two cups, namely the inner cup 102 and the outer shell 101 forming outer cup, are pushed together. Finally, it is also conceivable that the cup 100 consists of three nested materials, such as an inner cup 102 made of (smooth) plastic, an intermediate cup of foamed plastic and an outer shell 101 made of paper.

The different materials of a cup usually also perform different functions. For example, the inner cup 102 should prevent leakage of liquid contained therein, while the outer casing 101 should be well printable and, optionally, should also provide thermal shielding to the cup contents. Finally, the idea of environmental protection when using a cup made of composite material plays a crucial role.

The masses of disposable cups that are needed on a daily basis, require highly automated manufacturing processes or machines for producing the same. Although the currently known methods or machines meet existing needs, there is room for improvement, in particular to be able to cope with the future - in all likelihood increased - demand for disposable cups or to reduce the number of parallel machines.

The object of the invention is therefore to provide a machine and a method which enables an improved production of cups made of composite material and in particular a shortening of the cycle times.

The object of the invention is also achieved with a method for producing a cup made of composite material, namely from an outer shell and an inner cup, according to claim 13, namely with a method comprising the steps:

• Carrying out at least one of the steps: providing a development of the outer shell, winding the development onto or into a first holding device, pressing and / or bonding ends of the development wound on or into a first holding device to form a seam region, in at least one in the region of a first Holding device, which is arranged on a first rotatably mounted star- or wheel-like holding device carrier, arranged first workstation,
• Passing a finished outer shell from a first holding device to a second holding device, which is arranged on a second rotatably mounted star or wheel-like holding device carrier, in the region of a transfer station,
• Performing at least one of the steps: impressing the outer shell in or the inner cup on a second holding device, pressing a finished inner cup in the finished outer shell or pressing a finished outer shell on the finished inner cup, control of the finished cup, sorting out defective cups, removing the finished cup from the second holding device in at least one second workstation arranged in the region of the second holding device, and
• Performing at least one of the following steps prior to providing the unwinding of the outer wrapper in a preparatory station: singulating a wrap of an outer wrapper from a stack, pre-bending the seam region, heating a seam region or the entire process, applying adhesive in the seam region, and thereby
• the application of the adhesive is carried out with at least one first nozzle facing the seam region, wherein the at least one first nozzle is moved parallel to a conveying plane and transversely guided with respect to the conveying direction of the unwinding, and
• the transverse displacement of the first nozzle is carried out in the vertical direction with respect to the conveying direction of the unwinding, and
• the transverse adjustment of the first nozzle for applying the adhesive is carried out simultaneously with the conveying movement of the unwinding.

According to the invention, a plurality of first holding devices, which are arranged on a first rotatably mounted star- or wheel-like holding device carrier, advantageously interact with a plurality of second holding devices, which are arranged on a second rotatably mounted star or wheel-like holding device carrier. On the first holding devices, an outer shell is prepared so far that it can be transferred to a transfer station to the second holding devices and there is merged with the inner cup. It is advantageous that the machine is relatively compact due to the use of wheel or star-like Haltevorrichtungsträgem. Also rad- or star-like structures are relatively easy to produce and little prone to error. According to the invention thus results in a robust, compact and less error-prone machine, which also allows very short cycle times.

In particular, if the outer sheaths are not delivered ready prepared so that they can be wound directly around a first holding device, in the area of the machine according to the invention nor the necessary preparations can be made. The listed steps are to be seen as demonstrative examples. Of course, other or additional steps are possible.

If at least one nozzle is provided in the preparation station for the application of adhesive, which is adjustably guided transversely with respect to the conveying direction of the unwinding, the application of adhesive is thus substantially facilitated in cooperation with the blank. If the transverse adjustment of the nozzle for applying the adhesive takes place simultaneously with the conveying movement of the unwinding, this relative movement with respect to one another with the smallest space requirement for the nozzle arrangement can be used.

"Done" in the context of the invention is not necessarily "completely finished", but refers to the achievement of at least the state of the outer shell / the inner cup / cup, which is absolutely necessary for the implementation of the upcoming work step. For example, the outer shell may be still unprinted before bonding and (someday) later printed. "Ready" for the gluing means, for example, that the outer shell is wrapped and the adhesive flaps are coated with adhesive.

Advantageous embodiments and modifications of the invention will become apparent from the dependent claims and from the description in conjunction with the figures of the drawing.

• mehrere dritte Haltevorrichtungen, welche auf einem dritten drehbar gelagerten stern- oder radartigen Haltevorrichtungsträger angeordnet sind,
• zumindest eine im Bereich der dritten Haltevorrichtungen angeordnete dritte Arbeitsstation zur Ausführung zumindest eines der Schritte: Vereinzeln der fertigen Innenbecher von einem Stapel, Auftragen von Klebstoff auf die Außenseite des Innenbechers und
• eine Übergabestation zur Übergabe eines fertigen Innenbechers von einer dritten Haltevorrichtung an eine zweite Haltevorrichtung.

An advantageous variant of the machine according to the invention comprises the following components:

• a plurality of third holding devices, which are arranged on a third rotatably mounted star or wheel-like holding device carrier,
• at least one arranged in the third holding devices third workstation for performing at least one of the steps: singulating the finished inner cup of a stack, applying adhesive to the outside of the inner cup and
• a transfer station for transferring a finished inner cup from a third holding device to a second holding device.

In this way, inner cup, which are not yet ready prepared to be delivered to the machine according to the invention to be directly connected to the outer shell, still be prepared within the machine according to the invention. For example, an adhesive can be applied to the inner cup, so that it bonds well with the outer shell. In a particularly advantageous variant of the invention, the transfer station consists of a compressed-air nozzle in a third holding device, with the aid of which the inner cup is transferred from a third to a second holding device can. In principle, other transfer stations may consist of a compressed-air nozzle, for example the transfer station between the first and second holding devices. This works particularly well when the outer shell is also designed in the form of an (outer) cup.

It is also advantageous if the workstation for winding the settlement of the outer shell on a mandrel formed as a first holding device brushes, which embrace the settlement upon rotation of the first holding device carrier U-shaped on the mandrel or if the workstation for winding the settlement of the outer shell on the formed as a mandrel first holding device comprises levers which completely wrap the U-shaped pre-bent development around the mandrel. Here is the settlement of the outer shell pre-bent during the rotation of the first holding device carrier by laterally arranged brushes U-shaped. Levers then take the not yet bent ends of the settlement, they bend completely around the mandrel and press them. By the brushes a particularly gentle bending of the development takes place, whereby a damage of the often sensitive outer surfaces of the outer sheath is prevented. The brushes are advantageously still, but can also be moved. Moreover, it becomes clear from this variant of the invention that the execution of a process step is not necessarily limited locally to a work station on which a first holding device carrier stops. Rather, a process step, as has been shown, even during the rotation of the same take place.

It is also favorable if the brushes and the two levers are held stationary relative to the first holding device carrier on the machine frame of the machine. This workstations are set at certain points at which predetermined steps are performed. This can be found with fewer machine parts Auslangen.

It is advantageous if the preparation station comprises cooperating pairs of conveyor belts and the pairs are arranged in the conveying direction transversely to the conveying direction distanced from each other and thereby spanning a conveyor plane. This results in a clear clamping of the still planar windings to be transported. Thus, the staggered and isolated transactions are conveyed safely and precisely to the individual workstations.

It is also advantageous if the preparation station at the end of the first holding device carrier facing the end of the conveyor belts comprises a feed carriage with means for holding the settlement to form the outer shell and the feed carriage from a settlement of the conveyor belts taking over position in the settlement position providing for first holding device of the first holding device carrier is adjustable. This can be done a clear pre-positioning of the transaction to be transferred and this will be passed after their preparation to the winding station. By adjusting a relative placement with respect to the holding device is also possible, which simply the size ratios of the outer shell can be fixed.

It is also favorable if the means for holding the unwinding on the feed carriage are formed by bearing surfaces which are distanced from each other in the transverse direction with respect to the direction of movement of the feed carriage and in which suction openings open and these are in line connection with a suction inlet of a vacuum generator. Thus, the blank is gently held on its visually appealing exterior, without causing damage to be feared.
It is advantageous if between the transversely spaced support surfaces of the feed carriage in this a recess is formed, through which at least the first holding devices can be moved through when providing the settlement for forming the outer shell. This is up to the holder of settlement on the fixture a clearly prepositioned holder possible.
Finally, it is advantageous if the station for applying adhesive to the seam area is arranged on that side of the preparation station at which the end of the unwinding in the finished outer shell in the seam area is conveyed past. there then the winding of the blank can be done easily without being stripped during the winding process of the applied adhesive.

It should be noted at this point that the variants and possibilities mentioned for the machine according to the invention and the advantages resulting therefrom naturally also apply mutatis mutandis to the method according to the invention.

The above embodiments and further developments of the invention can be combined in any manner.

By way of introduction, it is stated that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals and component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the illustrated and described different embodiments may represent for themselves, inventive or inventive solutions.

The Fig. 2 shows a first variant of a machine 1 according to the invention in a greatly simplified representation. The machine 1 comprises first holding devices 2, here in the form of spikes, which are mounted on a first star-shaped or wheel-shaped holding device carrier 3. The machine 1 further comprises second holding devices 4, here in the form of sleeves or rings, which are mounted on a second star-shaped or wheel-shaped holding device carrier 5.

Hereinafter, a part of the manufacturing process of a cup 100 will be explained. Before that, however, it should be pointed out that the work steps required for this purpose are shown merely symbolically, since a representation of the respectively assigned workstations of the machine 1 would damage the clarity in all details. In the following, reference will be made only to working steps, of course, but in the following explanations, the respective associated, objective work stations are meant.

Furthermore, it is pointed out that, between the working steps, the first or the second holding device carriers 3 and 5 continue to rotate by one position. The rotational movement is thus discontinuous. The rotational movement advantageously stops only for a certain period of time, which corresponds to the time required for the long-lasting operation. Therefore, it is also particularly advantageous to divide long-lasting steps into several individual steps:
In a first step A1 or at a corresponding workstation, a development or a blank for forming an outer shell 101, which is wetted with adhesive in the vicinity, is delivered and aligned (see also FIG FIGS. 5 and 6 ). The fixation of the settlement on the first Halvorrichtung 2 forming mandrel takes place here using a terminal block (see also Fig. 7 to 10 ). In a second step A2, the aforementioned development is wound around the mandrel. For this purpose, for example, pincer-like moving levers can be used, which press the settlement against the mandrel. In a particularly advantageous variant, the unwinding is wound around the mandrel during the rotational movement of the first holding device carrier 3 with the aid of brushes (see Fig. 7 to 10 ). It becomes clear from this example that the production steps can not necessarily take place only when a holding device carrier 3 and / or 5 is at a standstill, but also during their movement. In a third step A3, the seam of the outer shell 101 is pressed. For this purpose, a movable punch, in particular a heated punch, provided which presses the two ends of the development of the outer shell 101 against each other and to the first holding device 2, in particular the mandrel. The following two stations are empty and serve to cure the adhesive. It is also conceivable that optional workstations can be retrofitted at these positions.

The stamp, if it is part of a workstation, can be released once the adhesive has sufficient adhesive force to prevent the outer shell 101 from falling apart. The stamp can also be part of a first holding device 2. In this case, it can be connected to a clamping lever 26, which is adjustable, in particular pivotally guided or mounted on the first holding device carrier 3. Since the clamping lever 26 or the stamp is indeed moved with the holding devices 2, this remains closed until the adhesive is cured and thus pushes the two to be joined and overlapping ends of the settlement to form the erected outer shell 101 together and this to the first Holding device 2 or its mandrel. This variant is advantageous in that the cycle times are not unnecessarily prolonged because of the curing of the adhesive. In a fourth step A4, the finished outer shell 101 is transferred to a second holding device 4. This can be formed by a ring or a sleeve. The fourth step A4 is at the same time the first working step B1 in the region of the second holding device carrier 5. The transfer can be effected, for example, by a displaceable ring or a sleeve-shaped slide (forms the transfer station 6 in this example), which at least dissolves the finished outer shell 101 from the mandrel or even stripped off and optionally simultaneously pushes into the second holding device 4, in particular the ring. In this case, the transfer or the takeover of the outer shell 101 can also be effected by a directed medium flow, in particular an air flow, as will be described later.

Optionally, the outer shell 101 can also be pulled by means of a vacuum in the ring. It is also conceivable that the outer shell 101 is removed by means of pliers from the mandrel.

In the next step B2, the outer shell 101 is postponed, that is correctly inserted into the receptacle of the second holding device 4, in particular the ring, since their correct fit to the transfer station 6 can not always be guaranteed. Guide rods 7 advantageously prevent the outer shell 101 from falling out should it not correctly seat the second holding device 4 and thus prevent a secure hold by the vacuum. In a next step B3, the prefabricated inner cup 102 is inserted into the outer shell 101.

In an advantageous variant of the inner cup 102 is pressed with the aid of compressed air from a tube and can be spent in the prepositioned held outer shell 101.

Furthermore, it would also be possible for the inner cups 102 prepared for the transfer or takeover to be grasped at their bottom and thus drawn into the outer casing 101 held there by the second holding device carrier 5. One possible arrangement of a transfer means 41 is in the following Fig. 18 shown in simplified form. Thus, for example, this may be rod-shaped, wherein at its bottom of the inner cup 102 end facing a vacuum holder is arranged. This may be, for example, a suction cup with a suction inlet of a vacuum unit. Thus, the transfer means 41 can be adjusted from a position detecting the cup bottom and thereby protruding through the ring of the second holding device 4 into the position arranged within the second holding device carrier 5.

In a next step B4, the inner cup 102 is postponed or snapped into the outer shell 101, if in the course of the insertion process, no complete latching between the bead of the inner cup 102 and the bottom facing the lower edge of the outer shell 101 has taken place. By pressurization or by means of a punch, not shown, it can be achieved that the bottom of the inner cup 102 in particular bulges outward and so the engagement of the attached to the inner cup 102 bead is facilitated, since so the outer dimension of the same is reduced so far that the clear passage cross-section on the outer shell 101 does not have to be overstretched. Optionally or additionally, the inner cup 102 may already be supplied wetted with adhesive. Optionally, the bead in the bottom region of the inner cup 102 can be omitted if the adhesive ensures that the outer shell 101 reliably adheres to the inner cup 102. The latter, however, is disadvantageous in that it makes the separation of waste after use of the cup 100 more difficult. Optionally, the Nachsetz can be omitted. Thus, the steps B3 and B4 can therefore also be combined, for example when the inner cup 102 is inserted into the outer shell 101 at high speed.

In a further step B5 it is checked whether the cup 100 has been made properly (symbolized here with a camera). If this is not true, the cup 100 is transported into a waste container, for example via a pipe system in step B6. If the cup 100 is OK, it will be taken off the ring in a final step B7. This can be done for example by means of a blast of compressed air, which blows the cup 100, for example in a connected delivery pipe. One of the workstations, in this case the workstation B8, is not occupied with its own work step and thus free. But it would also be possible to provide this free station elsewhere or to prove this with a necessary additional step. This order is chosen only as an example and can be freely adapted to your needs.

As mentioned, the inner cup 102 can already be supplied wetted with adhesive. This preparation can also be done in the machine 1. In the following the necessary steps are explained:
In a first step C1, the inner cups 102 delivered in a stack are occasionally pushed onto a third holding device 8 which is mounted on a third holding device carrier 9 is arranged. The separation can take place with the aid of rollers with a spiral groove, in which the cup rim engages, take place (see also 3 and 4 ). The third holding device carrier 9 moves in time with the two other holding device carriers 3 and 5 and thus moves the inner cup 102 to the next workstation. In a second step C2, the inner cup 102 is wetted by means of nozzles with adhesive, in particular with hot adhesive. The next workstation is again shown empty. In a final step C3, the inner cup 102, which is wetted by adhesive, is then pushed into the provided outer casing 101 by the third holding device 8, which is also formed by a mandrel, for example. The step C3 thus corresponds to the step B3.

As mentioned, the development of the outer shell 101 can also be supplied already wetted with adhesive. The preparation of the settlement can also be done in the machine 1. In the following the necessary steps are explained:
In a first step D1, the unwinds delivered in a stack are separated and deposited on a turntable 10. The separation can be done by fanning the stack by means of compressed air and suction of the lowest settlement. The turntable 10 in turn moves in time with the holding device carriers 3, 5 and 9. In a second step D 2, the adhesive flap (in particular the later inner flap) can be pre-bent, so that the outer surface 101 laterally in the overlap region as flat as possible in the sense of roundness becomes. In a next step D3, the development is heated or only the tabs to be bonded are heated in order to accelerate the later bonding process. Optionally, the settlement can also be embossed. If the stamping press is heated, moreover, a separate step for heating can be dispensed with. In a fourth step D4, the adhesive is applied, here with a nozzle. It is advantageous if the nozzle moves linearly over the seam area, while ejecting adhesive and in their rest or parking position with the help of a rotating, wet sponge, cleaned and kept open (see also Fig. 14 ). It is also conceivable, of course, to apply the adhesive, for example, with a roller. Optionally, the adhesive is also applied at elevated temperature. Finally, in a last step D5, the transfer into the area of the first holding device carrier 3 takes place. Step D5 thus corresponds to step A1. The turntable 10 has recesses for this purpose, through which the mandrels can move through.

At this point, it is noted that the axes of rotation of the holding device carrier 3, 5 and 9 and the turntable 10 is not necessarily - as in Fig. 2 shown - have to be parallel. It is conceivable, for example, that the axis of rotation of the turntable 10 are vertical and the axes of rotation of the holding device support 3, 5 and 9 are arranged horizontally. The axes of rotation of the holding device carrier 3, 5 and 9 and the turntable 10 can also take any angle to each other, as long as care is taken that the axes of the holders 2, 4 and 8 are aligned at the transfer stations or at least arranged so that a smooth Transfer of the outer shell 101 or the inner cup 102 is ensured.

The 3 and 4 now show that the wetting of the inner cup 102 with adhesive does not necessarily have to be performed on a holding device carrier 9. Instead, for example, a conveyor belt 11 may be provided, on which the inner cup 102 delivered in a tube 12 is deposited individually, wetted with adhesive and transferred to a second holding device 4 (note: the second holding device carrier 5 is in FIG Fig. 3 for the sake of simplicity only shown equipped with a holding device 4). The singulation can take place, for example, with the aid of rollers 13 or wheels, which have a helical groove into which the edge or cover flange of the inner cup 102 engages (see the detailed view). Fig. 4 ). Upon rotation of the roller 13 of the bottom inner cup 102 is separated from the stack until it finally falls out of the groove on the conveyor belt 11. The steps C1 to C3 correspond to the steps already described and are therefore not explained in detail.

The Fig. 5 (Side view) and 6 (top view) now show that the preparation of the development of the outer shell 101 also does not necessarily have to be performed on a turntable 10. Instead, the unpackages separated by a stack for forming the outer shell 101 can be clamped between a work table 14 and a conveyor belt 15 and thus conveyed. During the (discontinuous) movement of the conveyor belt 15, the unwinds are pre-bent, heated, wetted with adhesive and brought into a transfer position. The windings move because of their high speed even without the drive by the conveyor belt 15 on the work table 14 continue to be gently braked by the bristles of a brake brush 16 and then move slowly with the help of the guide rails 17 on the stop blocks 18. There they are held with the help of a vacuum that acts through holes on the work table 14 on the settlement. From this position, they are taken over by a first holding device 2, which moves through a recess in the work table 14. As soon as the development of the outer shell 101 is in contact with the first holding device 4, in particular the mandrel, it is held in place by means of a clamping strip (see also here FIGS. 7 and 8 ). The steps A1 to A4 correspond to the steps already described and are therefore not explained in detail. (Note: the first holder carrier 3 is in the FIGS. 5 and 6 for simplicity, only equipped with a holding device 2).

The Fig. 7 to 10 show the process when the unwinding of the outer shell 101 by means of brushes around the mandrel formed by the first holder 2 is wound (step A2). The Fig. 7 schematically shows the mandrel and the direction of movement thereof, two preferably fixed brushes 19, two levers 20 in their rest position and a terminal block 21, which is the center of the development of the outer shell 101 (here in side view and in the Fig. 7 just shown) against the thorn presses. The mandrel is still in a first rest position, that is, the discontinuously moving first holder carrier 3 is still here for the acquisition process of the provided settlement still.

In Fig. 8 the mandrel has already moved on somewhat due to the rotational movement of the holding device carrier 3, so that the development of the outer casing 101 has in the meantime come into contact with the two brushes 19 arranged laterally with respect to the movement plane of the first holding device carrier 3 and is bent around the mandrel.

In the Fig. 9 the mandrel has moved into another intermediate position. As a result of this relative movement between the holding device carrier 3 with its first holding devices 2 and the brushes 19 arranged here with respect to the machine 1, the blank is applied starting from its ends to the mandrel of the holding device 2. The brushes 19 have already bent the development of the outer shell 101 in this position U-shaped around the mandrel. There is a movement until the position shown the Fig. 10 reached which represents a further short rest position for the moving first holding device carrier 3.

The Fig. 10 now shows the state in which the lever 20 have performed their pincer-like movement and completed. The blank or the unwinding was completely wound around the first holding device 2. Thus, the two ends of the settlement can be connected in an overlapping seam to each other to the outer shell 101 in cooperation with the previously applied adhesive. The pressing of the overlapped ends to the first holding device 2, in particular the mandrel, is effected by the above-described clamping lever 26 or punch. The individual clamping levers 26 are arranged with respect to the holding devices 2 designed as mandrels, as seen in the direction of rotation of the first holding device carrier 3, the rear peripheral region of the mandrels. These are optionally adjustable with the stamps arranged thereon from a position distanced from the mandrel into a position resting on the mandrel, in particular pivotable. If the two ends of the development are fixed relative to one another in this way, the two levers 20 can be returned to their initial position, in which case the further movement of the first holding device carrier 3 into the next predetermined holding position takes place. The clamping lever 26, optionally with its punch, also remains during the further movement of the first holding device carrier 3 in its adjacent position on the mandrel and is moved together with the first holding device carrier 3. Each of the first holding devices 2 is assigned its own clamping lever 26 or stamp. The complete curing of the adhesive can then take place during the further movement of the holding device carrier 3.

Once the adhesive force of the adhesive is sufficient to prevent falling apart of the now finished outer shell 101 because of the internal stresses, the clamping lever 26 can be moved back to its rest position. This is preferably done very late in order to maintain the longest possible pressing pressure on the overlap seam. Preferably, the release takes place shortly before reaching the transfer station 6. The lever 20 are in the example described in the field of a workstation, so fixed, arranged. Alternatively, however, the levers 20 can also be arranged on a first holding device 2 and be moved together with this or the first holding device carrier 3. Furthermore, the brushes 19 are not necessarily curved but can also be straight. After all For example, the brushes 19 can also be moved to facilitate the winding process. In particular, rotating brushes are conceivable here.

The Fig. 11 shows that the invention is not bound to the star-shaped arrangement of the holding devices 2, 4 and 8 on their Haltevorrichtungsträgem 3, 5 and 9. Rather, these - as well as in Fig. 11 shown - be arranged in the manner of a revolver magazine. In the Fig. 11 For example, first holding devices 2 in the form of spikes on a first holding device carrier 3 and second holding devices 4 in the form of sleeves on a second holding device carrier 5 are arranged. The second holding device carrier 5 is designed in the form of a wheel. The workstations can be analogous to those in Fig. 2 be shown work stations and are therefore not shown in detail. The changed position of the holding devices 2, 4, in particular of the mandrels and the sleeves, may result in more favorable space conditions in the arrangement of the workstations, so that the machine 1 may be more compact overall. In addition to the workstations, the machine 1 also includes a transfer station, which is opposed by a mandrel and a sleeve, so that the finished outer shell 101 can be inserted or inserted from a mandrel into a sleeve.

The axes of the spines are in the Fig. 11 aligned parallel to the axis of rotation of the first holding device carrier 3 and the axes of the sleeves parallel to the axis of rotation of the second holding device carrier 5. This is not a mandatory circumstance. Rather, it is also possible that the axes are tilted outwards or inwards. However, care must be taken that the axes of the mandrels and the sleeves are aligned at the transfer station, so that a smooth transfer of the finished outer shell 101 is possible.

Fig. 12 shows another example similar to those in the Fig. 2 and Fig. 11 illustrated examples, but in which the first holding devices 2 are arranged in a star shape on the first holding device support 3 and the second holding devices 4 in the manner of a revolver magazine on the second holding device carrier 5. The axes of the holding device carrier 3 and 5 are aligned at right angles to each other. Again, the first and second holding devices 2 and 4 can be arranged obliquely to the axis of rotation of the respective holding device carrier 3 and 5. The angle between the axes of rotation of the two Holding device carrier 3 and 5 is then adjusted if necessary, so that the axes of the holding devices 2 and 4 are aligned at the transfer station.

The Fig. 13 now shows a modified form of the first holding device 2 in the form of a retractable mandrel. Several, rotatably mounted segments 22 are distributed over the circumference of the mandrel. In the winding position, the segments 22 are folded outwardly, so that their envelope substantially describes the inner shape of the outer shell 101. In this position, so the outer shell 101 can be made. After the outer shell 101 is completed and has arrived at the transfer station, the segments 22 are folded inwards, so that the outer shell 101 can be moved in the direction of the arrow. At the transfer station, the outer shell 101 can then be pushed onto an inner cup 102, which sits on a second holding device 4 (in this case a mandrel).

The most significant difference from the previously illustrated machines 1 is therefore that the first and the second holding device 2 and 4 are designed as mandrels and the outer shell 101 is pushed onto an inner cup 102 and not the inner cup 102 is inserted into an outer shell 101. This can have production engineering advantages. For example, the inner cup 102 can be grasped and held at its edge by means of a pliers-like device, so that the bottom of the inner cup 102 can be pressed from inside to outside with a punch (not shown) to facilitate the assembly process of the outer shell 101.

The Fig. 14 finally shows how a nozzle 23 for adhesive application (usually preferred cold and / or hot glue) by means of a rotating sponge 24, which dips into a water basin 25, can be kept clean. After the application of adhesive (shown in phantom), the nozzle 23 moves back into its rest position, in which excess adhesive from the nozzle 23 is wiped.

In the FIGS. 15 and 16 a further and possibly independent embodiment of a preparation station for providing a settlement is shown, again for like parts, the same reference numerals or component designations as in the preceding Fig. 1 to 14 be used. To avoid unnecessary repetitions, will to the detailed description in the previous Fig. 1 to 14 referred or referred.

Here, a similar arrangement for providing a blank is shown, as previously in the FIGS. 5 and 6 is done. In contrast to the illustration described above, the blank or the unwinding is conveyed here by cooperating pairs of conveyor belts 15, the pairs being arranged distanced transversely to one another as viewed in the conveying direction and thereby defining a conveyor plane 27 for the blank between them. The individual developments for forming the outer shell 101 are separated from a stack in a first step D1 and thus transferred to the two cooperating conveyor belts 15. In a further workstation of this preparation station, in a second step D2, the adhesive flap, in particular the later inner flap, can be pre-bent, as has already been described above. In the same workstation, it is also possible to simultaneously perform a third step D3, in which the settlement is at least heated. In this case, only that portion of the settlement can be heated, which forms the tabs to be bonded. The station of pre-bending or pre-breaking - D2 - of the seam area is here arranged on that side of the preparation station, at which the inside of the finished outer shell 101 in the seam area end of the settlement is conveyed past. In the present embodiment, the pre-bending station - D2 - is arranged at the other end than that of the adhesive application.

In a further, subsequent workstation takes place in the fourth step D4 of adhesive application.

In the embodiment shown here, the adhesive is applied in the course of a simultaneous movement of both the nozzle 23 and the blank or the settlement in the transport direction by means of the conveyor belts 15. The nozzle 23 is used to apply the adhesive in the seam area, which parallel to the conveying plane and transverse with respect to the conveying direction of the settlement is guided adjustable. The transverse adjustment of the nozzle 23 is preferably carried out in the vertical direction with respect to the conveying direction of the settlement. This is simplified by a double arrow. This transverse adjustment of the nozzle 23 for applying the adhesive takes place simultaneously and in coordination with the conveying movement of the Completion. As a result, a preferably continuously running adhesive bead 28 can be applied at correspondingly coordinated movement speeds relative to one another between the nozzle 23 and the unwinding.

In hitherto known adhesive application devices, the further transport of the development in the area of the adhesive application station has been stopped and carried out with the aid of a correspondingly aligned, angular movement relative to the conveying direction of the adhesive application by means of the nozzle 23.

In the present case, it is now possible to assign the first nozzle 23 and a further nozzle 29 for the adhesive order or directly next to it and so simultaneously apply two such adhesive beads 28 in the region of the tabs to be bonded in a single, common movement. The two adhesive beads 28 are applied here in the region of that tab, which is arranged lying outside in the finished erected state of the outer shell 101. Thus, the two previously described lever 20 without stripping the adhesive perform the winding movement for the complete winding process.

After the adhesive has been applied, the unwinding is transferred by means of the cooperating conveyor belts 15 at their end facing the first holding device carrier 3 to a feed carriage 30. At this feed carriage 30, the previously described, lateral guide rails 17 and the position in the conveying direction defining stop blocks 18 are preferably again arranged. If unwinding is in the prepositioned position on the feed carriage 30, this means are designed to hold it. In this case, the feed carriage 30 is adjustable from a position in which the unwinding of the conveyor belts 15 takes place into the position providing the unwinding - A1 - towards the first holding device 2 of the first holding device carrier 3. In this way, the unwinding is conveyed from the area of the conveyor belts 15 into the swivel area of the first holding devices 2 in the area of the first holding device carrier 3. This transferred position of settlement is in the Fig. 16 shown. The feed carriage 30 is indicated here only in simplified dashed lines.

The above-described means for holding the unwinding on the feed carriage 30 are formed here by bearing surfaces 31 distanced from one another in the transverse direction with respect to the direction of movement of the feed carriage 30, in which intake openings 32 open. These are conductively connected to a suction inlet, not shown, of a vacuum generator. As a result of the built-up negative pressure, the unwinding conveyed by the conveyor belts 15 is taken over and held in the positioned position on the feed carriage 30. In this prepositioned and held position, the adjustment of the feed carriage 30 takes place in the swivel range of the first holding device 2.

Furthermore, it is shown in simplified form that between the transversely spaced support surfaces 31 of the feed carriage 30 in this a recess 33 is formed, through which when providing - A1 - the settlement to form the outer shell 101 at least the first holding devices 2 can be moved therethrough. Thus, for the transfer of the settlement from the feed carriage 30 toward the first holding device 2, the unwindings are held until the transfer takes place from the first holding device 2, as has already been described above. Immediately following the takeover of the settlement of the feed carriage 30 toward the first holding device 2, the shaping of the blank is carried out to the finished rolled outer shell 101, as shown in the Fig. 7 to 10 has already been described.

In contrast to the above-described mounting the settlement on the first holding device 2, in particular the mandrel, by means of the clamping bar 21, here the holder of settlement on the mandrel by at least one opening in the peripheral region of the first holding device 2 opening 34. Preferably, however, more of these Openings 34 are provided which are in fluid communication with a line 35 arranged in the mandrel. This line 35 and thus the openings 34 are further connected to a suction of a vacuum generator not shown in line connection. The arranged in the mandrel openings 34 are arranged on the first holding devices 2 respectively on the seen in the direction of rotation of the first holding device carrier 3, the front peripheral region. In this section, the first system of settlement takes place on the holding device. 2

In the Fig. 17 is another and possibly independent embodiment of the first holding device 2, in particular its mandrel, in the region of the first holding device carrier 3, wherein again for the same parts the same reference numerals or component designations as in the preceding Fig.1 to 16 be used. In order to avoid unnecessary repetition, the detailed description in the previous ones will be used Fig. 1 to 16 referred or referred.

As before in the Fig. 2 described, the transfer station 6 is provided in the region of the transfer station A4, B1 between the first holder carrier 3 and the second holder carrier 5. In the present exemplary embodiment, a sleeve 36 which is displaceably mounted in the axial direction with respect to the mandrel is arranged on the first holding device 2, which is designed as a mandrel, in each case on its end region closer to the holding device carrier 3. This sleeve 36 can be adjusted axially relative to the mandrel according to registered double arrow. This can preferably be done for releasing the outer shell 101 formed from the blank from the winding mandrel. Due to the conicity of the winding mandrel, a clearance is created by this detachment process between the inside of the outer shell 101 and the mandrel and can thus be transferred to the second holding device carrier 5, in particular the second holding device 4 designed as a ring, in the region of transfer - A4, B1 become.

In order to facilitate the transfer of the finished wound outer shell 101, it is advantageous if at least a first outlet opening 37 opens at the periphery of the first holding device 2, which is designed as a mandrel, and these are line-connected to a pressure generator (not specifically illustrated here), in particular for compressed air is. In order to achieve a more uniform transfer, it is advantageous when seen over the circumference of the formed as mandrels, first holding devices, a plurality of such outflow openings 37 are provided or arranged. Particularly preferably, in the area of the first outflow opening 37 or the first outflow openings 37, a circumferentially extending channel 38 can be arranged in the first holding device 2 designed as a mandrel. In this case, the first outflow opening 37 or the outflow openings 37 open into the channel 38. In order to achieve a directional transfer, starting from the first holding device 2 towards the second holding device 4, it is advantageous if the first outflow opening 37 and / or the channel 38 is aligned such that this one on the from the center of the first holding device carrier 3 facing away side directed discharge direction. It will possible to pass the wound outer shell 101 into the receptacle of the second holding device 4.

In the Fig. 18 is a further and possibly independent embodiment of the second holding device 4, in particular of the ring or hollow mandrel shown, again with the same parts the same reference numerals or component names as in the preceding Fig. 1 to 17 be used. In order to avoid unnecessary repetition, the detailed description in the previous ones will be used Fig. 1 to 17 referred or referred.

The ring-shaped, second holding device 4 serves to receive the wound in the first workstation outer shell 101 and subsequently for inserting the inner cup 102 for completing the cup 100th

In order to facilitate the transfer or takeover of the outer shell 101 from the first holding device 2, it is advantageous to arrange or provide at least one second outflow opening 39 in an inner peripheral region, the second holding device 4 designed here as a sleeve or ring. Preferably, a plurality of such second outflow openings 39 are distributed uniformly over the circumference and can be conductively connected via a distribution channel with a pressure generator, in particular for compressed air.

The second outflow openings 39 are aligned such that they each have a directed toward the first holding device 2 of the first holding device carrier 3 outflow direction. Preferably, however, the outflow direction is directed towards the center of the mandrel. By appropriate steering of the medium flow starting from the second outflow opening 39 toward the mandrel 2 and deflection thereof, the transfer of the outer shell 101 into the second holding device 4 takes place in the manner of a countercurrent movement.

Furthermore, it is shown here that at least a second opening 40 of a pipe arranged in the sleeve or the ring opens at the inner circumferential region, formed as a sleeve or ring, second holding device 4, which optionally with the interposition of a distribution channel with a suction of a vacuum generator in line connection stands. As a result, the outer shell 101 inserted into the second holding device 4 can be kept fixed at its outer periphery. This transfer or takeover of the outer shell 101 from the first holding device 2 to the second holding device 4 takes place at the interface of the workstations A4, B1. The repositioning of the outer shell 101 described above or positioning thereof in the second holding device 4 as well as the further, subsequent working steps can be carried out analogously to the description of how this has been done in detail beforehand.

The above-described transfer of the blank or the unwinding from the feed carriage 30 to the first holding device 2 can be determined depending on the selected relative end position of the feed carriage 30 to the mandrel of the first holder 2, the size ratio of the outer shell 101 to be produced. The further the feed carriage 30 is adjusted towards the center of the first holding device carrier 3, the larger the outer casing 101 is produced in its circumferential dimension, in particular its diameter. If a not so wide adjustment, the circumferential dimension is reduced accordingly. By this deliberate adjustment, not only the joining process between the inner cup 102 and the outer shell 101 can be varied, but also the clamping force of the outer shell 101 are fixed to the inner cup 102. The narrower or smaller the outer shell 101 is produced, the more firmly it sits on the inner cup 102.

In the Fig. 19 is a further and possibly independent embodiment of the machine 1 is shown, again for like parts, the same reference numerals or component names as in the preceding Fig. 1 to 18 be used. In order to avoid unnecessary repetition, the detailed description in the previous ones will be used Fig. 1 to 18 referred or referred.

The holding device carrier 3, with its first holding devices 2 arranged thereon for the production of the outer shells 101 from the windings, may be of analogous design, as already described in US Pat Fig. 2 has been described. The axis of rotation of the first holding device carrier 3 is preferably arranged horizontally lying.

The second holding device carrier 5 with its second formed as sleeves or rings, second holding devices also has a preferably horizontal axis of rotation on. In contrast to the embodiment described above, although the two axes of rotation of the first and second holder support 3, 5 are aligned parallel to each other, but in the transfer station 6 - A4, B1 - the longitudinal axes of the two holders 2, 4 crossing each other, in particular at right angles , aligned with each other.

The transfer takes place here by a separate transfer device 42, which is formed for example by a lifting and pivoting mechanism. The transfer device 42 has, for example, a vacuum suction device and pulls with it the finished outer casing 101 from the first holding device 2 in the axial direction until a pivoting movement by an angle of e.g. 90 ° is feasible. Thus, in the present embodiment, a pivot angle is achieved, which corresponds to the relative orientation of the second holding device 4 with its longitudinal or receiving axis. At a different angle of inclination of the two longitudinal axes of the first holding device 2 and the second holding device 4 to each other, the pivot angle to be performed is to be adjusted accordingly.

In the position of the outer shell 101 that is to be received in the second holding device 4, this is encompassed by a gripping tongs 43, shown schematically in simplified form, on its outer circumference. Since the outer shell 101 is formed from a circumferentially relatively unstable material, this can additionally be supported by a by the second holding device 4 in the axial direction thereof adjustable collet 44, which receives the outer shell 101 on the inside fitting, inside. By means of this collet 44, the pre-positioned by the gripping tongs 43 held outer shell 101 is then taken, and used in the second holder 4 or pulled. Subsequent to this insertion process, in turn, the pre-positioned impressions can be done in a separate workstation, as has been previously described for the workstation B2. Subsequently, the insertion of the inner cup 102 can be made in the prepositioned outer shell 101. This can be done by means of a third holding device carrier 9 and disposed thereon, third holding devices 8, as also in the Fig. 2 previously described. This transfer station is labeled B3, C3. The loading of the third holding devices 8 with the inner cups 102 can be carried out analogously, as has already been described in detail previously.
