Definitions

  • the invention relates to a conveyor system for viscous, pasty or solid in the cold state, in particular for hot-melt adhesive, according to the preamble of claim 1.
  • viscous, pasty or solid masses are processed.
  • sheet metal processing industry in particular in the automotive industry, there is an ever increasing trend towards bonding sheet metal parts.
  • a major problem with these working techniques is the conveyance of viscous, pasty or, in many cases, solid masses, especially hot-melt adhesives.
  • the mass, together with the delivery container usually a sheet metal container, is arranged in a cylindrical steel tube.
  • the lid of the sheet metal container is removed and the pressure plate of a piston pump is inserted into the container from above.
  • the wall of the steel tube can be heated. This liquefies the usually solid adhesive.
  • DE-A-2248699 describes a device for processing hot melt adhesives, which has a storage container with a manual conveying device for the still solid adhesive.
  • a heating chamber is connected to the storage container made of a plastic tube.
  • Conveyor, storage container, heating chamber and nozzle are one behind the other.
  • EP-A-0319666 shows a tubular bag pack for paste-like filling goods. It consists of a flexible hose jacket and an emptying element consisting of an end element and an emptying nozzle.
  • the tubular bag has any number of chambers running in the axial direction with different filling materials, e.g. Basic, hardener and color components.
  • the end link, nozzle and sealing cap form a rigid unit after connection to one another.
  • the conveyor system should, if possible, manage without additional pumping devices.
  • the masses should be stored within the low-cost container, which can be completely emptied without degradation or deterioration of the mass properties.
  • the emptied container should only represent a small volume of waste.
  • the conveyor system 1 for example shown in FIGS. 1 and 2, comprises an essentially tubular housing 2.
  • One side of the tubular housing 2 is provided with a melting plate 5 releasably connected.
  • the opposite end is open and designed to receive a piston 14 seated on a piston rod 15.
  • This piston can be moved in the housing 2 by means of pneumatic, hydraulic or electrical means 16.
  • the piston 14 could also be designed to be manually displaceable.
  • the piston 14, as shown in FIG. 1 is also arranged entirely within the housing 2, even in the fully retracted state. This and a sufficient dimensioning of the length of the piston 14 ensures safe operation without tilting the piston 14.
  • the housing 2 is arranged upright, with the melting plate 5 at an upper end and the piston 14 at its lower end.
  • this arrangement could also be interchanged, or the housing 2 could be in a lying position.
  • the tubular housing 2 is designed to receive a viscous, pasty or solid M which is assigned within a compressible bag 19.
  • the filled bag 19 has an approximately cylindrical shape with a diameter d that is slightly smaller than the inner diameter i of the tubular housing 2.
  • the outside 20 of the bag 19 has a surface that is as smooth as possible, preferably it is metallized. Together with the surface of the housing inner wall 3, which is also as smooth as possible and which is preferably polished, the bag 19 and the housing inner wall 3 counteract the compressive force of the piston 14 with the lowest possible frictional force.
  • the wall thickness b of the bag 19 is selected to be 0.1 mm to 1 mm, preferably approximately 0.3 mm.
  • the means 11 for heating the housing wall 4 are essentially arranged only in the area of the melting plate 5.
  • the heating means 11 are preferably arranged in the melting plate 5. This heating means 11 liquefies the part of the mass located in the front region of the bag 19, which protrudes into an approximately conical recess 6 in the side 7 of the melting plate 5 facing the housing interior.
  • the conical recess 6 extends from the housing inner wall 3 to a preferably centrally arranged discharge opening 8 in the melting plate 5.
  • the discharge opening 8 is connected via a channel 9 to a hose connection 10, preferably provided on the lateral outer wall of the melting plate 5.
  • the pressure of the piston 14 pushes the bag 19 with the mass M in the direction of the melting plate 5.
  • the liquefied part of the mass M is pressed out of the bag 19 by predetermined breaking points formed as slits 22 in the side 21 of the bag 19 facing the head 5 and via the dispensing opening 8 and the channel 9 and a hose 17 connected to the hose connection 10 to form an application gun 18 headed.
  • the hose 17 is preferably heatable.
  • the slots 22 preferably extend in a star shape from the bag center.
  • FIG. 2 shows the situation with a bag 19 that has already been partially emptied and compressed. Upon further pressing, the bag 19 is compressed to a very small volume.
  • the melting plate 5 shows a section through the melting plate 5.
  • the central discharge opening 8, the channel 9 and the hose exclusion 10 are clearly visible.
  • the approximately conical depression 6 in the inside 7 of the melting plate 5 is indicated.
  • the heating means 11 preferably comprise electrically operable and controllable heating cartridges. These are arranged in a star shape around the central delivery opening 8.
  • the dispensing head 5 also has a radial bore 12 for a temperature sensor 13. This temperature sensor 13 detects the desired working temperature and is fed back via the heating means 11, so that the temperature can be regulated as precisely as possible.
  • the melting plate 5 is detachably connected to the housing 2. For operational safety, it is advantageous to design the melting plate 5, the housing 2 and all connections to be pressure-resistant.
  • the housing 2 is made of steel with a wall thickness z of 1 mm to 20 mm.
  • the melting plate 5 is also made of steel, its inside 7 is preferably coated with polytetrafluoroethylene (PTFE)
  • FIG. 4 shows an example of a container for use in the conveyor system 1 according to the invention.
  • the compressible bag 19 with the mass M is arranged within a protective tube 23.
  • the inner diameter m of the protective tube 23 is slightly smaller than the inner diameter i of the tubular housing 2.
  • the wall thickness of the protective tube 23 is dimensioned such that the protective tube 23 sufficiently counteracts a deformation of the filled bag 19. In this way it is ensured that the bag 19 maintains its shape during storage and transport and is always easy to insert into the tubular housing 2.
  • the conveyor system according to the invention in particular for hot-melt adhesive, can be produced as a larger stand system for containers with a mass of up to 50 kg and more. It does not necessarily require elaborate pumps pen needed. Due to the fact that only a small part of the mass has to be liquefied, there are no degradations or deteriorations in the adhesive properties and the pouch is fully used. There are hardly any pollution problems and the volume of waste is greatly reduced. In addition, the container is simple and cheap to manufacture.
