Definitions

  • the invention relates to a conveyor system for viscous, pasty or solid in the cold state, in particular for hot-melt adhesives, 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 the 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.
  • a conveyor device for smaller amounts of viscous, pasty or solid materials in the cold state is also known.
  • This device is designed in particular for the application of hot-melt adhesives.
  • the adhesive which is solid when cold, is located in a piston cartridge.
  • Piston cartridges of this type have a displaceable piston-like base and an outlet opening on the side opposite the base.
  • the filled piston cartridge is introduced into an approximately cylindrical container of this cartridge press, so that the outlet opening is connected to an application syringe adapted to the respective purpose.
  • the wall of the cylindrical container can be heated over its circumference and over its entire length in order to liquefy the contents of the piston cartridge. Only in the liquid state is it possible to apply adhesive to the application syringe by applying pressure to the bottom of the cartridge.
  • the conveyor system should do without additional pumping equipment.
  • the masses should be stored within a low-cost container that 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 according to the invention shown for example in FIGS. 1 and 2 comprises an essentially tubular housing 2.
  • One side of the tubular housing 2 is detachably connected to a dispensing and / or application head 5.
  • the opposite end is open and designed to receive a piston 14 seated on a piston rod 15.
  • This piston can be displaced 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 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 dispensing and / or application head 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 accommodate 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 same if possible smooth surface of the housing inner wall 3, which is preferably polished, the bag 19 and the inner wall 3 of the compressive force of the piston 14 oppose the lowest possible frictional force.
  • the wall thickness b of the bag 19 is selected to be approximately 0.1 mm to approximately 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 dispensing and / or application head 5.
  • the heating means 11 are preferably arranged in the dispensing and / or application head 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 dispensing and / or application head 5 facing the interior of the housing.
  • the conical recess 6 extends approximately from the housing inner wall 3 to a preferably centrally arranged dispensing opening 8 in the dispensing and / or application head 5.
  • the dispensing opening 8 is located above a channel 9 with a preferably on the lateral outer wall of the dispensing and / or application head 5 provided hose connection 10 in connection.
  • the pressure of the piston 14 pushes the bag 19 with the mass M in the direction of the dispensing and / or application head 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 heating means 11 preferably comprise electrically operable and controllable heating cartridges. These are arranged approximately in a star shape around the central delivery opening 8.
  • the dispensing and / or application 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 dispensing and / or application head 5 is detachably connected to the housing 2.
  • the housing 2 is therefore preferably made of steel with a wall thickness z of approximately 1 mm to approximately 20 mm.
  • the head 5 is also preferably made of steel, its inside 7 preferably coated with polytetrafluoroethylene (PTFE)
  • the compressible bag 19 with the mass M is arranged inside 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 transportation 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 both as a larger stand system for containers with a mass of up to 50 kg and more, and also as a small conveyor system for small amounts of adhesive in the form of a cartridge press for cartridges with a content of about 1 kg.
  • the conveyor system can also be integrated directly into the application gun. No complex pumps are required. Due to the fact that only a small part of the mass has to be liquefied, no degradation or deterioration of the adhesive properties occurs and the contents of the bag are 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.
