Definitions

  • the present invention relates to a tube filling machine with automatic adjustment for automatically adapting the parts of the machine to the processing of tubes of different lengths.
  • Tube filling machines are used to fill and close cylindrical tubes made of aluminum, plastics, polyfoil, laminated materials and the like, which are used in the cosmetics and pharmaceutical industries and in similar fields.
  • the devices currently used to change the size of the tubes to be processed in a tube filling machine are currently mostly of three kinds.
  • a first device uses a fixed tube supporting plate, or "transfer”.
  • the tube closing clamps, the device for orientating the notch of the tube, the cleaning device, etcetera are installed outside the tube supporting plate or tube supporting chain and each one is manually vertically adjustable.
  • a second type of device uses a tube supporting plate (transfer) which is manually adjustable along a vertical axis.
  • the tube closing clamps are fixed and are mounted outside the tube supporting plate.
  • the device for orientating the notch of the tube, the cleaning device, etcetera are instead installed in a fixed position outside the tube supporting plate. In this case, too, one has the above-described drawbacks.
  • the tube supporting plate (transfer) is manually adjustable along a vertical axis
  • the tube closure clamps are fixed and installed on a fixed support, centrally with respect to the tube supporting plate
  • the device for orientating the notch of the tube is installed on a fixed support, centrally with respect to the tube supporting plate.
  • German Document DT 25 45 760 A1 discloses a tube filling machine of the same kind of the one set forth in the preamble of claim 1.
  • An aim of the present invention is to provide a tube filling machine in which it is possible to automatically adjust the parts of the machine in order to process tubes of different lengths without having to replace or manually adjust said parts.
  • An object of the present invention is to provide a tube filling machine which has a single adjustment for setting all the devices for processing the lower open part of the tubes.
  • a further object of the present invention is to provide a tube filling machine which allows to monitor the current processing at all times from outside the machine.
  • a further object of the present invention is to provide a tube filling machine which allows simplified cleaning of the surface of the machine, access being allowed from all sides.
  • a further object of the present invention is to provide a tube filling machine which has simplified maintenance with respect to conventional machines.
  • a further object of the present invention is to provide a tube filling machine which is highly reliable and relatively easy to produce at low costs.
  • the tube filling machine comprises a frame 100 which forms a supporting surface 200 for a fixed lower section, whose function is to perform all the treatments on a tube 5 at the stopper end.
  • the fixed section comprises a tube supporting plate 1, or transfer, which is suitable to support, in stations 2, the tubes 5 to be processed.
  • the tube supporting plate 1 is rotationally actuated by a conventional jogging unit or Maltese cross 150.
  • the tubes 5 arrive at the plate 1 from a container 3, inside which they are loaded and from which they exit to be placed vertically along the circumference of the tube supporting plate 1 at a plurality of stations 2.
  • a container designated by the reference numeral 4, is filled with a liquid, creamy substance or other substance
  • the fixed section is rigidly coupled to the surface 200 of the tube filling machine.
  • An upper movable section arranged coaxially to the fixed section, comprises a first head 6 and a second head 7.
  • the second head 7 supports a plurality of actuation cams 8 for a matching number of clamps 9 which are suitable to close the open bottom end of a tube 5 and are supported by the first head 6.
  • a device 10 for orientating the notch of the tube 5 (the orientation device is installed on the head 7) and a photocell 11 (installed on the head 6)
  • a device 12 for detecting the presence of a tube 5 on the tube supporting plate 1 (the detector 12 is installed on the head 7)
  • a device for pushing tubes 5 onto the tube supporting plate 1 and a photocell for checking the exact positioning of the tube 5 on the tube supporting plate 1.
  • the heads 6 and 7 can move axially with respect to the fixed section of the tube filling machine (i.e., with respect to the tube supporting plate 1) and the head 7 can move axially with respect to the head 6.
  • Fig. 2 shows in detail the connection between the fixed section and the moving section of the tube filling machine.
  • the fixed lower section and the movable upper section are installed on a hollow shaft 13 which can rotate about its own axis and accommodates a movable shaft 17.
  • first head 6 is fitted on the hollow shaft 13, whilst the second head 7 is fitted on the movable shaft 17.
  • the hollow shaft 13 is actuated by movement means which advantageously comprise a gear 14 and a sprocket 15.
  • the gear 14 is keyed on the hollow shaft 13, which is threaded in its upper portion, for example with a trapezoidal thread.
  • the gear 14 is actuated by a gearmotor 16 which is in turn controlled by control means, for example of the programmable logic type, which are constituted by a PLC 16.
  • the PLC 16 is accommodated within a compartment designated by the reference numeral 300 in Fig. 1, which illustrates data entry and display means 301 which are suitable to set the adjustments of the moving parts of the tube filling machine according to the invention.
  • the movable shaft 17 is coaxial to the hollow shaft 13.
  • Said shaft 17 is capable of moving vertically along its own axis and is actuated by eccentric means 18 which are keyed on a driving shaft 19 of the tube filling machine.
  • Motion transmission means conveniently constituted by a tab 20, transmit the rotary motion of the hollow shaft 13 to the movable shaft 17, which is also threaded at the upper end lying opposite with respect to the tube supporting plate 1.
  • the thread of the movable shaft 17 is the same as the thread of the hollow shaft 13 and has the same pitch.
  • a ring 21 with a thread which is the same as the thread of the hollow shaft 13, is mounted on the first head 6 and allows to connect the head 6 to the hollow shaft 13.
  • the ring 21 thus allows to adjust the position of the first head 6 along the hollow shaft 13 by screwing the ring on said shaft.
  • First locking means 22 are suitable to lock the first head 6 after each adjustment.
  • the locking means are constituted by pneumatic means.
  • a second ring 23 with the same thread (and therefore with the same pitch) as the hollow shaft 13 is fitted on the second head 7, and its position can be adjusted along the movable shaft 17 by screwing.
  • Second locking means 24, similar to the first locking means 22, are suitable to lock the second head 7 in position after adjustment.
  • the first and second heads 6 and 7 are adjusted manually by a handwheel and mechanical devices, or electrically by an electric motor which is assisted or not by a PLC or with a pneumatic device which is controlled or not by a PLC.
  • the hollow shaft 13 passes inside hollow supporting means 25 fitted on the surface 200 of the tube filling machine; said means are suitable to support rotation-preventing means 26, on which a rod guide member 27 is mounted which is suitable to connect the first head 6 and the second head 7 to each other.
  • the rod guide member 27 is inserted in guiding bearings 28 and 29 which are accommodated in the first and second heads 6 and 7 respectively.
  • the positions of the first and second heads 6 and 7 are adjusted by acting on the threaded rings 21 and 23 respectively. These adjustments are performed either electrically or pneumatically, with or without the control of a PLC.
  • the position of the rings 21 and 23 is set according to the adjustment designated by the reference numeral 50 in figure 2, which corresponds to the maximum possible stroke of the rings on the hollow shaft 13.
  • the automatic adjustment of the rings 21 and 23 allows to process tubes of different lengths on the tube filling machine.
  • the locking means 22 and 24 allow to stably lock the set adjustment of the rings 21 and 23.
  • the tubes 5 arranged in the container 3 then descend, one at a time, from the container 3 towards the tube supporting plate 1, where they are accommodated in the stations 2.
  • the driving shaft 19 of the tube filling machine rotates under the actuation of a motor (not shown), and its rotation causes the eccentric element 18 keyed thereon to perform a cycle; this entails an ascending and descending motion of the second head 7 with respect to the first head 6 along the vertical axis of the hollow shaft 13.
  • the tube supporting plate 1 instead remains fixed and so does the head 6.
  • the ascending and descending motion of the second head 7 with respect to the first head 6 is designated by the reference numeral 60.
  • the second head 7 supports a plurality of cams 8 for actuating a plurality of clamps 9 for closing the tubes 5.
  • the clamps close the bottom end of the tubes 5.
  • the setting of the chosen rotation rate at the gearmotor 16 through the adjustment and control means allows to move the heads 6 and 7 monolithically by turning the hollow shaft 13 and the movable shaft 17 on which the heads 6 and 7 are respectively fitted.
  • the heads 6 and 7 can in fact move simultaneously, since they are interconnected by the rod guide member 27, which can slide freely in the guiding bearings 28 and 29 accommodated respectively in the heads 6 and 7.
  • the presence of the rotation-preventing element 26 causes the movement of the head 6 and of the head 7 to occur exclusively along the vertical axis of the hollow shaft 13.
  • the rotation of the hollow shaft 13 is transmitted to the movable shaft 17 by means of the tab 20.
  • the heads 6 and 7 therefore move upwards and downwards and are retained by the rotation-preventing means 26.
  • the head 7 then moves vertically up and down with respect to the head 6.
  • the tube filling machine according to the invention fully achieves the intended aim, since it allows to move the upper moving section of the machine with respect to the fixed lower section by means of a central control with a single automatic simultaneous adjustment of all the tube processing devices.
  • the materials used may be any according to requirements and to the state of the art.
