Definitions

  • the invention relates to a device for supplying liquid glue to a glue applicator according to the preamble of claim 1.
  • Packing machines of the tobacco processing industry pack blocks of a certain number, e.g. 20, cigarettes in packets or boxes or several packets of cigarettes in larger containers, for example in sticks or boxes.
  • appropriate packaging material blanks are folded around the packaged goods (cigarette blocks, packet arrays, etc.) and glued in predetermined closure sections.
  • the glue required for the adhesive is applied to the packaging material blanks by means of a glue apparatus integrated into the machine, which has a corresponding application unit for transferring glue to the blank and a device for feeding the glue to the application unit.
  • FIG. 1 Such a glue apparatus according to the prior art is shown in FIG. 1. It has a glue tray in which a certain glue supply is kept ready. The supply of glue from an upstream reservoir is switched on via a valve when the glue level in the tub falls below a predetermined level, and blocked again as soon as it reaches its intended maximum. A removal roller is immersed in the glue tub, the circumference of which removes a layer of glue from the tub and delivers it either directly to a blank to be glued or to a packaging material web or to other rollers of an application unit. This device will be dealt with in more detail in the description of the figures. A similar glue apparatus is also shown in EP 0 492 950 A1, where, however, the glue is fed to the glue tub into which a removal roller is located immersed, is not shown.
  • a disadvantage of these known gluing systems is that, at least when using PVA glues, the rotating removal roller can cause foaming after a short operating time. This increases the surface of the glue supply in the glue pan, which can thus react intensively with the air. The result is the formation of a skin on the glue surface, which falsifies the measured values of the fill level sensor for controlling the glue supply to the tub.
  • the solid glue skin simulates a fill level for the sensor, which can be far below the actual glue level under the skin.
  • the glue supply to the articles to be glued can be disrupted and even completely interrupted.
  • Another disadvantage is that the valves required for the glue supply to the glue roller can result in glue incrustations, which lead to blockage of the valves and thus also to malfunctions. The device therefore requires constant monitoring and maintenance. In addition, the dispersion of the glue is destroyed by the continuous movement of the removal roller in the glue tub, so that the glue in the tub wears out very quickly, with its adhesive strength weakening.
  • the invention has for its object to provide a further device of the type described above.
  • a particularly preferred continuation of the invention is the characterizing part of claim 2, because the active suction of the excess from the removal container by the overflow on the surface of the glue supply removes foam which is particularly effective, which leads to a very reliable and low-maintenance operation of the device.
  • the design of the device according to claim 3 represents a particularly preferred variant because it does not require any installations in the removal container for the overflow and also allows a very simple adjustment of the glue level in the removal container without additional moving seals being required.
  • Claim 4 relates to an embodiment of the device in which the overflow is firmly integrated in the removal container.
  • Claims 6 and 7 relate to configurations of the pump for sucking off the excess and the resulting foam from the removal container, with the advantage that several extraction containers can be taken into account with one pump at the same time.
  • Claim 8 relates to the specification of a special glue for use in packaging machines in the tobacco processing industry.
  • the invention offers the advantage that the foam formation in the glue container of a glue apparatus is effectively counteracted.
  • the provision of an overflow in the removal container allows the glue to be supplied to the removal container in excess, thereby a constant glue circuit between the storage container and the removal container is made possible. Peeling off the foam prevents the formation of a skin on the glue, which makes gluing the blanks of the packaging material more reliable.
  • the level in the removal container is kept constant in a simple manner by the overflow, so that constant conditions are present for removing the glue by means of the removal roller. This results in very reproducible results when gluing the blanks. Feed valves, which can lead to malfunctions due to glue incrustations, are not required in the device according to the invention. This also increases the operational safety of the device.
  • the glue in the glue storage container is at least partially continuously replaced by the excess supply, the constant movement of the glue roller cannot destroy the dispersion of the glue, so that wear and tear of the glue, ie the loss of its adhesive force, is excluded.
  • the supply of the glue from the glue supply to the removal container by means of a pump increases the reliability of the supply.
  • FIG. 1 shows a device for supplying liquid glue to a glue application unit in a packaging machine of the tobacco processing industry, as is known in the prior art.
  • This device has a removal container 1 in the form of a glue tray, which contains a glue supply 2.
  • a removal roller 4 rotating in the direction of the arrow 3 dips into the glue supply 2 and removes a glue layer on its circumference from the supply 2, which layer either transfers it directly to the object to be glued or to other transmission means of an order work (not shown).
  • a filling level sensor 6 is provided which acts on a valve 7 with which the glue supply from a storage container 8 is controlled as a function of the filling height of the glue in the removal container 1.
  • the fill level in the removal container 1 is kept substantially constant by opening the glue supply through the valve 7 when the glue level in the removal container falls below a predetermined level, and is stopped when the fill level sensor 6 detects that a preset upper glue level has been reached.
  • the glue supply 8 Since the glue supply from the glue supply 8 takes place in this known arrangement solely due to gravity, the glue supply 8 must be arranged very high above the removal container 1 in order to ensure a sufficient glue flow. This complicates the manual refilling of the glue supply 8. In addition, the constant movement of the removal roller 4 in the glue contained in the removal container 1 wears out the glue very quickly as a result, as a result of which the adhesive strength decreases, because the dispersion of the glue is destroyed.
  • the device schematically shown there for supplying liquid glue to a glue application unit in a packaging machine of the tobacco processing industry like the device shown in FIG. 1, again has a removal container 1 with a predetermined amount of glue 2.
  • the removal roller 4 rotating in the direction of the arrow 3 is immersed in the glue.
  • the glue is fed to the removal container by means of a pump 9 from a glue storage container 11.
  • the amount of glue in the storage container 11 is monitored by means of a floating switch 12 which is only indicated schematically and, if necessary, supplemented in a known manner.
  • the pump 9 conveys the glue from the storage container 11 through a feed line 13 into the removal container 1.
  • the amount of glue which the pump 9 conveys from the storage container 11 into the extraction container 1 is greater than the amount of glue discharged from the extraction container by the extraction roller 4 .
  • the glue is conveyed in excess to the removal container 1 by the pump 9.
  • an overflow 14 is provided through which the Excess flows away.
  • the U-shaped end of the return line 16 dips into the removal container 1 from above and is arranged such that the open leg of the U-tube 16, as an overflow 14, determines the filling level of the glue 2 in the removal container.
  • the return line 17 is connected to the suction side of the pump 9, which in the overflow produces a suction which draws off the excess and the foam which forms in the removal container 1. Since the overflow 14 is arranged in the conveying direction of the removal roller 4 in front of the roller, where the foam that forms preferably collects, the foaming glue is reliably removed from the removal container by the suction, so that it cannot impair the gluing of the packaging material.
  • the return line 17 leads from the pressure side of the pump 9 back into the storage container 11. The glue foam sucked out of the removal container 1 together with the excess dissolves in this storage container.
  • a multi-chamber diaphragm pump is preferably used as the pump 9, to which both the feed line 13 and the return line 17 are connected.
  • other glue devices can be connected to this glue pump.
  • Figure 2 shows the removal container 18 of such an additional glue apparatus, which is also fed with glue via the feed line 13.
  • the overflow 14 for removing the excess glue supplied is in this case designed as a pipe socket 19 which is inserted into the bottom of the removal container 18. Via a return line 21, this pipe socket 19 is connected to the glue pump 9 and further to the storage container 11, in which the pump 9 pumps back the excess and the foam that forms.
  • a removal roller 22 is again immersed in the removal container 18.
  • a pump that can be used advantageously here is, for example, the compressed air diaphragm pump of the type AD 15 EEE from Almatec Maschinenbau GmbH, D-47475 Kamp-Lintfort.
