Definitions

  • the invention relates to a device for loading a continuously operating container closing machine with lids, the lids being fastened to the containers with the aid of at least one closing tool, which rotates on a tool carrier in a circular path while maintaining a horizontal orientation of the lower surface of the tool.
  • Such a device is e.g. B. from GB-PS-923 741 known.
  • a continuously operating container closing machine is described, wherein closing tools are moved in a rotating tool carrier arranged above the transport path on a circular path.
  • the closing tools are positively guided so that the bottom surfaces of the tools remain horizontally aligned.
  • the individual tools periodically lower themselves onto the individual containers that are conveyed under the rotating tool carrier and thereby fasten cover foils on the containers.
  • the lid foils are loosely attached to the containers in a separate lid station.
  • the lid station lies in front of the rotating tool carrier when viewed in the transport direction. In this station, a cover film tape is pulled off a cover film supply roll.
  • cover film sections are separated from the film web and placed more or less loosely on the containers transported through the cover station.
  • the containers then move on to the closing station, where a closing tool lowers and the covers are then folded over, for example, around a horizontally projecting container edge.
  • This known device has several disadvantages. Firstly, it is disadvantageous that the lid films can initially only be placed loosely on the containers and then have to be conveyed over a certain conveying path to the actual closing station. This relatively large conveying path already harbors the risk of the covers slipping, but is also disadvantageous in particular in view of the relatively large space requirement of the overall device that this entails.
  • a further disadvantage of this known system is that the closing tools, which sink onto the containers loosely provided with the lids, can also cause displacements of the loosely deposited film with respect to the container when the containers are received, so that the devices with relatively large projections can be used for these devices Cover films must work over the edges of the containers to ensure that the containers are completely covered in any case when closing.
  • the object of the invention is to provide a device of the type mentioned at the outset, which makes it possible to precisely and economically place accurately placed lids on the containers for closing and which enables a compact construction of the entire closing machine.
  • a cover guide track is provided which is arranged so that it can be pivoted in the same direction over a transfer pivoting area of the closing tool and in alignment with cover guides on the closing tool, and in that a cover feed device is provided which moves the cover when passing through the transfer pivoting area pushes out of the mouths of the Dekkef guide track into the cover guides on the closing tool.
  • the invention thus provides that the closing tools are provided with lids of a suitable size during their circulation on the tool carrier by inserting them into lid guides attached to the closing tools for this purpose.
  • the closing tools then lower the lids themselves onto the containers, so that the containers are thus provided with the lids directly at the point of closure. Since the closing tools themselves position the lids on the containers, there can be no shifts on any intermediate transport routes. Since the cover guide track of the transfer device carries out a pivoting movement aligned with the cover guides on the closing tool over a certain transfer pivoting area, there is therefore sufficient time available to insert the covers into the cover guides on the closing tool without the circumferential closing tools having to be stopped. This allows fast and continuous loading of the closing tools.
  • the device according to the invention makes it possible to fasten both prefabricated lids and lids which have only been manufactured in the device precisely and simply in a continuous movement with the aid of the closing tools on continuous containers. Since the lid feed or loading is carried out spatially in the area of the closing station, the entire sealing machine can be made compact.
  • An advantageous embodiment of the invention provides that the cover guide track is part of a swivel frame which is attached to a fixed support via parallel pendulum arms, that the pivot axes of the pendulum arms on the carrier side lie in a horizontal plane with the axis of rotation of the tool carrier, and that the effective length W of the pendulum arms corresponds to the radius R of the circular path of the closing tool.
  • This configuration enables the cover guide track to pass through a swivel area with a swivel radius in a pendulum movement in the same direction, which corresponds to the radius of the circular path of the closing tool. This allows the alignment of the cover guide track to be aligned in a simple manner to the cover guides on the closing tool over the transfer swivel area.
  • a further embodiment of the invention provides that a cutting device is arranged in the cover guide track with which individual cover film sections are separated from a cover film track.
  • the cutting device makes it possible to separate cover film material drawn off from a cover film supply roll into film sections each of a size required for a cover, and then to insert these film sections into the cover guides on the closing tool.
  • a cutting device is not required if the loading takes place with already prefabricated lids.
  • embossing elements are arranged in the cutting device, which produce offset end profiles on the cover film web and on the separated film section during the cutting process in the width direction. With such embossing elements it is achieved that the separated film section is pushed out of the cover film track from the cover guide track into the cover guides on the closing tool during the passage through the transfer pivoting area, without separate feed or drive elements having to be present for this.
  • the end profiles ensure that the cover film web and the separated film section do not slide over one another, but instead abut one another at the separating edge so that the desired pushing out is reliably achieved.
  • the profile elements can be arranged in such a way that the end profiling on the cover film web and on the film section point in the same direction. While in principle it is also possible to have the end profiles on the cover film web and on the film section point in different directions, an equidirectional profile prevents the cover film web and film section from sliding over one another after separation.
  • a further embodiment of the invention provides for one side of the embossing elements, preferably the die side, to be made from a rubber-elastic material. When using such a material, a smooth, unprofiled pressing surface is sufficient in itself.
  • a further embodiment of the invention provides for the cover guideway from the cutting device to the mouth to be designed as a film bed formed from individual bars.
  • the bars which are arranged next to each other across the width of the film web and at two levels one above the other to create a guide gap, prevent the separated film sections from twisting or sticking when being pushed out and transferred into the cover guide on the closing tool.
  • a suitable choice of the guide gap height which is dimensioned only slightly higher than the cover film, also ensures that the end profiles reliably cause the pushing out, even if the film should sag a little downward or protrude upward in some areas of its cross section.
  • a modified embodiment of the invention provides that the cover guide track has upper and lower guide elements to form a guide gap starting behind the cutting device in the feed direction, which are designed such that the guide gap extends in a zigzag shape in the width direction.
  • the above-described embossing of the cut edges in the area of the cutting device with the aid of embossing elements provided specifically for this purpose can be omitted.
  • the knife used in the cutting device need not have a cut adapted to the profiles. After the entry into the guideway, the cover film is shaped in a wave or zigzag shape, so that after the cut has been made, a horizontally facing front edge of the cover film path then abuts a zigzag rear edge of the cover film section.
  • the subsequent film web reliably pushes the cut off lid film section further in the guideway. If, during the feed movement, the cover film web is also pushed so far into the guideway that it has passed through a first enlarged inlet mouth area, it also deforms in a zigzag shape, but nevertheless reliably pushes the cut off cover film section further, because due to the tension in the material constant contact with the parts of the guide elements causing the zigzag shape is ensured, so that the abutting edges cannot slide over or under each other.
  • Solid profiled guide plates, offset round rods or also guide plates with mutually projecting profile ribs can be provided as guide elements.
  • a clamping device acting on the cover sheet is provided, which is arranged to be vertically displaceable relative to the swivel frame, but is non-displaceable horizontally.
  • this clamping device When this clamping device is actuated when the transfer pivoting area is reached, it holds the film web firmly, so that the film web executes a relative movement to the pivoting frame when pivoting the same. This relative movement can then be used to push out the film section separated at the cutting station with the help of the end profiles and at the same time to introduce a new piece of film web for the next film section into the cover guideway.
  • the clamping device thus allows together with the profiling elements, a simple implementation of a cover feed device.
  • a further development of the invention also provides that a drive for the swivel frame is provided which moves the swivel frame in the same direction when passing through the transfer swivel area with the corresponding rotational speed of the tool and which swivels the swivel frame away from the tool at a higher speed after passing through the transfer swivel area.
  • This drive which makes it possible to swing the swivel frame out of the movement path of the closing tool after passing through the transfer area at a greater speed in order to enable its free further movement, can be derived, for example, from a curve, cam disc or the like, which in turn, by means of a push rod Depending on the set number of cycles and thus the set rotational speed of the closing tools is driven. As a result, the movements of the swivel frame are synchronized with the rotational movements of the closing tool.
  • An alternative embodiment provides that the cover guide track for passing through the transfer pivoting area is brought into contact with the cover guides of the closing tool and driven against the force of a spring by means of the rotating tool.
  • This solution eliminates the need for a separate drive because the swivel frame is swiveled by the locking tools themselves.
  • the spring ensures that the mouth of the cover guideway lies securely on the closing tool. Passing through a second swivel range after completion of the transfer at a higher speed can be carried out in this connection with control bars which rotate with the rotating tool carrier and, by suitable coupling with the swivel frame, thus control its movements synchronized with the rotary movement of the closing tools.
  • the latter After the tool has left the coupling area with the cover station, the latter returns to the starting position by spring force - but equipped with a damping device - in order to transfer the next cover into the next tool.
  • FIG. 1 a container closing machine 1 is shown, which is equipped with a loading device 2 according to the invention.
  • the container closing machine has a closing station, generally designated 5, to which individual open containers 3, for example filled with foodstuffs, are fed in succession with the aid of a conveyor belt 4.
  • the containers are moved continuously by the closing machine 1 and closed at the closing station 5 during their passage.
  • closing tools 6 and 7 on the arms of the closing tool carrier 8 designed as a rotating wing are deflected in a circular path K around a central shaft 9.
  • the loading device transfers 2 cover film sections to the individual closing tools.
  • the closing tools then lower onto the containers and close them.
  • the closing process itself does not require any further explanation here. It should only be noted that, for closing, lower tools can also be suitably introduced to the containers, which then work together with the closing tools 6 and 7 in such a way that, for example, a crimp closure under high pressure or a sealing closure is produced.
  • the loading device 2 has a swivel frame 11, which is suspended with the aid of pendulum arms 12 relative to a fixed support 19 fastened to a frame 13, swinging around a certain swivel range.
  • This pivot frame carries a Dedcel Insertsbahn 20, which is periodically pivoted into the circular path K of the closing tool 7 or 6 by the pivoting movement of the pivot frame and is moved in the same direction on the circular path in the same orientation to the lid guides 30 formed on the tool surfaces during a cover transfer phase.
  • prefabricated lids are not used, but a cover film web 15, for example a metal film, is pulled off a cover supply roll 14, the cover film web being finally secured via a fixed roller system 16, a dancer roller system 17 and other suitable guide rollers via a deflection roller 18 on the swivel frame is deflected and conveyed in the direction of the cover guide track 20.

  • the closing tools 6 and 7 are each mounted in the closing tool carrier at a distance R (radius of the circular path K) in such a way that the lower tool surfaces and thus also the cover guides always run horizontally.
  • the effective length W of the pendulum arms 12, with which the swivel frame 11 is fastened relative to the fixed support 19, corresponds to the radius R of the rotating closing tools.
  • the axes 23 of the pendulum arms 12 lie in a common horizontal plane ME with the central shaft 9 of the tool carrier.
  • the synchronous drive for the rotational movement of the closing tool of the pivoting movement of the swivel frame is effected in the illustrated embodiment with the aid of a push rod 24 which engages one of the pendulum arms 12, which in turn by means of suitable drive elements with the drive M (see FIG. 1), which also drives the tool carrier in a manner not shown, is coupled.

  • the profiles are different in two Chen embodiments shown in Figures 4 to 7.
  • the end profiling is carried out in such a way that profilings 41 and 42 offset in the width direction arise, the profiling in the cover film section 31 pointing upwards, while in the cover film web 15 it points downwards (see FIG. 5).

  • the cover film web 15 in the area of the knife is still almost non-profiled and then goes between the guide rods in the not yet separated, more profiled cover 31 over.
  • the cut off lid foil section 31 assumes the shape which can be seen in FIGS. 15 and 15a.
  • the area of the cover immediately behind the separating knife arrangement at the level of the inlet opening 50 also has a profiling due to the elasticity of the material (metal foil), but in a weakened form, accepted.

  • FIG. 19 shows a further phase after the transfer has taken place.
  • the angle a designates a swivel range that is driven through by way of example, while the angle a 2 is intended to denote an angular section that accelerates through the loading system after the transfer has taken place, in order to get sufficient distance from the closing tool 7 during its further rotation.
