Definitions

  • the invention relates to a machine for processing packaging tubes, that is to say a machine which, starting from ready-made empty tubes, performs in succession the actions which what are known as tube fillers are capable of performing in-line.
  • Such actions or process steps usually comprise cleaning, cap tightening, tube print registration, filling, sealing and trimming of the tubes.
  • the invention relates to a machine with a very high production capacity and, for this purpose, a continuously operating machine has been designed.
  • Continuously operating packaging machines are known within a number of different packaging systems.
  • An example of such a machine is the continuously operating cartoner, in which products intended for packaging are conveyed synchronously with the blanks for cartons and in which the synchronization is maintained throughout the entire cartoning procedure.
  • Another example of continuously operating, packaging machines is machines with continuously driven endless conveyors provided with holders for packaging blanks/capsules which are to be processed in a number of working stations driven synchronously with the conveyor.
  • continuous packaging machines are found within the area of packaging of liquid food products, for example the machines in which a product is filled into a tube constituting a blank for the packaging, and working stations, which are movable synchronously with the advance of the tube, process the tube into finished packagings filled with the product.
  • the intermittently operating conveyor system is of course the correct one for the purpose.
  • the problem underlying the invention is to bring about such active processing times in all the working stations that a continuously operating tube handling machine is obtained.
  • Fig. 1 is a layout of a machine according to an embodiment of the invention
  • Fig. 2 shows the working principle of the processing tools in a station for cleaning tubes
  • Fig. 3 shows the working principle for the processing tools in a station for tube print registration
  • Fig. 4 shows the working principle for the processing tools in a station for filling
  • Fig. 5 shows the principle for the processing tools in a station for heat activation.
  • a continuously driven conveyor system or track comprising an endless conveyor 11, 12, 13, only the upper strands of which are shown in the figure. Vertically below each conveyor strand, therefore, are corresponding lower strands which are connected to the upper strands around guide rollers.
  • the conveyor 11 , 12, 13 is driven at a constant speed in the direction indicated by the arrow 23.
  • the conveyor 11 , 12, 13 is followed by a series of transport/transfer wheels 16-22 which are driven at a constant speed in the directions indicated by arrows.
  • the speed of rotation of the transport/transfer wheels is selected so that it is adapted to the continuously driven conveyor 11, 12, 13 in such a manner that the first wheel 16 successively removes and transfers to itself tube holders 24 (Fig. 2) fed on the conveyor part-section 13 as soon as they arrive at the wheel 16.
  • the arrangement for this transfer is not shown in the figures and can in principle consist of drivers.
  • the conveyor track comprising the part-sections 11 , 12, 13 (and the associated lower strands which are not shown) and the transport/transfer wheels 16-22 together form a continuously driven conveyor track in which said cassettes/tube holders 24 run in what is in principle an uninterrupted path with a predetermined centre distance between adjacent cassettes/tube holders (for example with the cassettes/tube holders bearing closely against one another).
  • Part of the straight conveyor section forms part of an infeed station where a robot 25, by means of a gripper 27, removes from transport packagings 26 for empty tubes rows of tubes located rectilinearly therein and inserts these into cassettes/tube holders following one another on the conveyor.
  • an outfeed station On the output side of the set of transport/transfer wheels 16-22, there is, adjacent to the straight conveyor part-section 11 , an outfeed station with a robot 28, the gripper 29 of which, in the exemplary embodiment shown, removes the same number of processed tubes as the robot 25 inserts and delivers the processed tubes to a continuously driven conveyor 30, of the pocket transfer type in the exemplary embodiment, for onward transport to a continuously operating cartoning machine 31.
  • FIG. 1 adjacent transport/transfer wheels rotate in opposite directions, and the individual wheels moreover have mutually varying peripherally effective or extending conveyor part-sections.
  • the conveyor part-section of the wheel 16 thus extends from the point where the wheel adjoins the straight conveyor part-section 13 forward to the "contact point" with the following wheel 17, which corresponds to a circular arc of roughly 180° according to said figure.
  • the next wheel 17 has an effective transport section corresponding to a circular arc of roughly 220°, the following wheel 18 a transport section of roughly 180° and the wheel 19 after that an even greater transport section, roughly 280°, the wheel 20 has a shorter transport distance, roughly 180°, the wheel 21 a longer transport section again, roughly 220°, _and the wheel 22 has a transport section of roughly 180°.
  • This difference between the transport sections of the various transport/transfer wheels provides an important partial solution to the problem mentioned in the introduction.
  • each transport/transfer wheel has a set of processing tools for performing a certain operation or process step, and, as mentioned in the introduction in connection with intermittent tube fillers, different process steps require different effective processing times.
  • the difference in the length of the effective transport sections of the wheel arrangements 16-22 is the starting point for mastering such effective processing times.
  • the transport/transfer wheel 16 thus has "processing tools" for cleaning, the station 17 has tools for tightening an opening arrangement for the tube (normally a cap), the wheel 18 has tools for tube print registration, the wheel 19 has tools for filling, the wheel 20 has tools for heat activation (in the exemplary embodiment shown hot-air activation), the wheel 21 has tools for squeezing the tube end together, and the wheel 22 has tools for trimming.
  • the processing tools in the various working stations are in principle arranged in fundamentally the same manner and are positioned along the entire periphery of the associated transport/transfer wheel and can be rotated with the latter.
  • the positioning along the entire periphery thus means that each wheel always has a surplus of tools in relation to the number of cassettes/tube holders located in the effective transport section of the wheel.
  • the accessibility of tools in all the processing stations (transport/transfer wheels), in spite of said inactive surplus of tools, does mean, however, that the effective transport sections along each wheel can be optimally used so that overall it is possible to run the system of transport/transfer wheels and tools continuously.
  • the wheel 19 has the longest effective transport section, and this has been selected in view of the fact that the process step to be performed over this transport section is that which takes the longest time in the present case, namely the filling step.
  • Fig. 2 thus shows the working tools for the wheel 16.
  • the robots in the infeed station and, respectively, the outfeed station in the exemplary embodiment shown are arranged so as each to handle twenty tubes at a time, there are altogether twenty processing tools in each processing station formed by the wheels 16-22.
  • Fig. 2 shows diagrammatically the wheel 16 supported in a machine stand 32 and driven rotatably via a belt transmission 33. Located peripherally equidistantly on the drive shaft 34 of the wheel 16 are blowing nozzles 35 with connections 36 for compressed air and an arrangement for height adjustment. Below the rotatable wheel 16, there is a circular plate 37 fastened on the machine stand 32, in which plate a cam-follower groove 38 is formed. The wheel 16 has holders (not shown) for the cassettes/tube holders 24, and arranged below the cassettes/tube holders are lifters 39, the vertical movement of which is controlled by said cam groove 38.
  • said holders (not shown) on the wheel 16 and the cassettes/tube holders 24 as well as the set of tools 35 are arranged equidistantly along the periphery of the wheel 16 and above the latter.
  • the effective transport section on the wheel 16 mentioned previously corresponds to a circular arc of roughly 180° and, as the effective transport section/processing section coincides with the lifters 39 being activated, it can be seen from the figure that altogether ten processing tools out of twenty are active and the others are thus in the passive part of the wheel Fig. 3 shows the processing tools assigned to the wheel 18 and intended to bring about tube print registration.
  • the basic illustration of the working sequence corresponds to that in Fig. 2.
  • a combination of spinners 40 and photodetectors 41 are used as processing tools and, as can be seen from the illustration on the left in the figure, use is made here of the same number of tools as in the process step according to Fig. 2.
  • Fig. 4 relates to the arrangement belonging to the wheel 19, that is to say the arrangement in the filling station, where the active transport section along the wheel is the maximum, roughly 270°, in view of the time necessary for filling.
  • processing tools that is to say filling nozzles 42, metering pumps 43 and cassettes/tube holders 24. It can be seen from the illustration on the left in Fig. 4 that altogether twelve processing tools are active over the effective transport section of the wheel 19.
  • Fig. 5 shows the circumstances of the wheel 20 in Fig. 1.
  • hot-air nozzles 44 for heat-activating the tubes which in this case are made of a material which allows such heat activation for sealing purposes.
  • the same number of hot-air nozzles as cassettes/tube holders and associated lifters 25 are likewise present in this case.
  • altogether ten processing tools (hot-air nozzles) are inactive during the transport of the tubes around the periphery of the wheel 20.
  • the tubes have been diagrammatically indicated in Fig. 5 by the part designated by number 45.

Abstract

L'invention concerne une machine destinée à effectuer les différentes étapes de transformation en vue de la production, à grande capacité, de tubes finis, au moyen d'un système convoyeur entraîné en continu. La machine présente une voie de convoyage comprenant des sections partielles linéaires conventionnelle (11, 12, 13), combinée avec une installation de roues de transport/transfert (16-22). En raison de leur positionnement, les roues de transfert forment des sections de transport efficaces pouvant être adaptées individuellement aux opérations de transformation respectives, pour des tubes présents dans des cassettes/porte-tubes dans le système convoyeur. Chaque roue présente des outils de transformation ayant le même espacement que toutes les positions des cassettes/porte-tubes et tournant avec la roue correspondante. Selon une forme d'exécution préférée, on utilise des robots (25, 28) pour l'amenée des tubes vides, respectivement, pour évacuer les tubes transformés de l'installation des roues de transport/transfert.
