Definitions

  • the EP 1 990 184 A1 describes a device for producing a conical sleeve for cups and / or a conical paper cup.
  • 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.
  • 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.
  • the transfer is made to a hollow shape of another rotary star, in which the embossing of the outer shell takes place.
  • glue is applied to insert the inner cup in the next prepared workstation in the thus prepared and already formed sleeve.
  • the final connection between the inner cup and the corrugated outer shell takes place.
  • 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.
  • the feeds of the blanks via its own feeding device, which is formed of parallel juxtaposed conveyor belts with driver elements.
  • 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.
  • this cup 100 there are several methods to make this cup 100.
  • One possibility is to wrap the outer shell 101 around the finished inner cup 102.
  • the inner cup 102 is usually received by a mandrel, which takes over the support and support during the winding process.
  • 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.
  • 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.
  • the inner cup 102 is made of foiled cardboard.
  • the outer shell 101 may also be made of plastic, in particular of foamed plastic.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • the machine is relatively compact due to the use of wheel or star-like Haltevoriquessträgem.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the blank is gently held on its visually appealing exterior, without causing damage to be feared.
  • 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.
  • 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.
  • 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.
  • 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:
  • 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 Halvortechnisch 2 forming mandrel takes place here using a terminal block (see also Fig. 7 to 10 ).
  • a second step A2 the aforementioned development is wound around the mandrel.
  • pincer-like moving levers can be used, which press the settlement against the mandrel.
  • 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.
  • a third step A3 the seam of the outer shell 101 is pressed.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the prefabricated inner cup 102 is inserted into the outer shell 101.
  • a transfer means 41 is in the following Fig. 18 shown in simplified form.
  • 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.
  • 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.
  • 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.
  • 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.
  • the inner cup 102 may already be supplied wetted with adhesive.
  • 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 is disadvantageous in that it makes the separation of waste after use of the cup 100 more difficult.
  • the Nachsetz can be omitted.
  • 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.
  • 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.
  • the inner cup 102 can already be supplied wetted with adhesive. This preparation can also be done in the machine 1.
  • 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.
  • the inner cup 102 is wetted by means of nozzles with adhesive, in particular with hot adhesive. The next workstation is again shown empty.
  • 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.
  • 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.
  • the adhesive flap in particular the later inner flap
  • the adhesive 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.
  • 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.
  • 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.
