Definitions
- the present invention relates to an adhesive fluid dispensing device.
- cartridges for silicone sealing compound are known, for example, in which the cartridge has a piston which can be actuated by a stamp provided thereon when it is inserted into a correspondingly formed dispensing device, so that the sealing compound flows out of a tip ,
- the object of the present invention is to provide an adhesive fluid dispensing device in which the use of hot-melt adhesives is possible without the need for compressed air.
- an adhesive fluid dispensing device with an adhesive fluid dispensing tip flowing from an adhesive fluid cartridge and a manually actuable adhesive fluid cartridge actuating stamp, it being provided that the adhesive fluid cartridge has a heating cartridge for heating the adhesive fluid onto a Stamp actuation is assigned sufficient temperature for the adhesive fluid dispensing tip flow.
- An essential aspect of the present invention is therefore to be seen in the fact that it is used for hot-applied adhesive fluids and dispensing devices for manually operated ones
- the adhesive fluid cartridge is primarily and / or exclusively heated by a heating cartridge arrangement, since the hot adhesive fluid that flows through the tip when the stamp is actuated is sufficient, if necessary after preheating by heat flow from the heating cartridge to heat a temperature sufficient for the flow.
- This allows a very simple design of the adhesive fluid dispensing device, since heating is only required at defined points and thus a simple design of an adhesive fluid dispensing device is also made possible if it is to be used for adhesive fluids such as hot melt adhesives, in particular PUR adhesives, which are only sufficiently low-viscosity when heated ,
- the dispensing tip can and will preferably consist of a highly thermally conductive material such as metal. This not only ensures a sufficiently high temperature resistance, but also ensures that the dispensing tip is preheated when heated by the flow of heat from the cartridge or heating cartridge and then when the adhesive fluid is dispensed by the adhesive fluid heated by the heating cartridge to a temperature sufficient for dispensing, that is pushed out of the cartridge, heated so much that there is no risk of solidification in the tip. At the same time, there may be lower temperatures at the tip due to contact with cold or colder material to be bonded.
- the dispensing tip is positively connected to the adhesive fluid dispensing device or the cartridge, in particular by screwing.
- the provision of a positive connection increases the thermal contact or the thermal contact areas and thus contributes to the quasi passive heating of the metal tip in adhesive fluid cartridges.
- the actuating plunger which presses the piston in the adhesive fluid cartridge in the direction of the tip in order to cause the heated adhesive fluid to flow out, does not act on the piston over the entire area, but only acts on it in a small area.
- the small area attack will preferably take place in the middle of the cartridge. This individually and / or in particular together contributes to the fact that only a small amount of heat is transferred to the stamp, which thus keeps the heat losses via the stamp low.
- this contributes to a reduced temperature at the end of the actuation, even if there are high temperatures inside the cartridge and / or at the tip; on the other hand, it also improves occupational safety and ease of handling and also enables longer work after switching off the heating or, with the same heating output, shorter heating-up times and / or a weaker design of the heating cartridge.
- a pistol-like or plier-like handle can be assigned to the stamp, which leads to further reduced actuation temperatures at the actuation end. Handling is also made easier.
- the heating cartridge is usually arranged around the cartridge in such a way that the cartridge content is heated not only from one side, but in particular from diametrically opposite sides and / or from several locations along the surface of the cartridge. In this way, uneven heating of the cartridge contents and thus local overheating can largely be avoided.
- the heating cartridge will preferably also isolate the adhesive fluid cartridge against heat loss and be designed such that it can be disconnected from a power supply during the adhesive fluid dispensing. This makes it possible to first heat the adhesive fluid dispensing device to a temperature at which an adhesive fluid cartridge content, such as a sufficient amount of polyurethane hot-melt adhesive or other hot-melt adhesives for certain bonds, is completely heated to the required temperature and, after heating, will ensure that the adhesive fluid dispensing device is not impaired by Power cord is good to use. At the same time, no heavy power supplies such as accumulators and the like have to be moved.
- an adhesive fluid cartridge content such as a sufficient amount of polyurethane hot-melt adhesive or other hot-melt adhesives for certain bonds
- Fig. 2 the representation of an adhesive fluid dispensing device with exemplary temperature information and pliers-like handle.
- FIG. 1 shows an adhesive fluid dispensing device 1 with an adhesive fluid dispensing tip 3 flowing from an adhesive fluid cartridge 2 and a manually operable one
- Adhesive fluid cartridge actuating stamp 4 the adhesive fluid cartridge 2 being assigned a heating cartridge 5 for heating the adhesive fluid to a temperature sufficient for the adhesive fluid dispensing tip flow when the stamp is actuated.
- the adhesive fluid dispensing device 1 is provided with a front handle 1 a, which is formed in one piece with a covering 1 b of the heating cartridge 5 and the adhesive fluid cartridge 2 located therein.
- a front opening lc is provided in the casing 1b, through which the adhesive fluid dispensing tip 3 protrudes.
- a guide (not shown in FIG. 1) for the adhesive fluid cartridge actuating stamp 4 is provided.
- the adhesive fluid cartridge 2 is a tinplate cartridge which is at least largely solid in the cold state and which has a screw thread 2a at its discharge end and which has a piston 2b on the side facing away from it, against which the adhesive fluid cartridge actuating stamp 4 rests.
- the piston 2b lies tightly against the inner wall of the cartridge without play and is slidable in it. It also seals the heated adhesive fluid against the ingress of air.
- the dispensing tip 3 is screwed onto the thread 2a of the adhesive fluid cartridge, as a result of which, when the cartridge is fixed in the adhesive fluid dispensing device 1, it is fixed relative to the latter and thus to the adhesive fluid dispensing device.
- the adhesive fluid dispensing tip 3 is formed of metal and has an adhesive fluid-flow channel 3 a, which has a shape required for a desired application width. This can favor spraying or spreading.
- the length of the adhesive fluid dispensing tip 3 is selected such that it can be flowed through when the adhesive fluid heated to operating temperature flows through it, without the risk of clogging, due to adhesive fluid cooling in the channel 3a.
- the walls 3b around the channel 3a have a sufficient thickness, and at the same time the mechanical stability is ensured.
- the walls can be formed, in particular to facilitate screwing onto or detachment from the adhesive fluid cartridge, in a shape that is easily attackable by tools, in particular hexagonal.
- the adhesive fluid cartridge actuating stamp 4 is formed from a sufficiently long metal rod 4a and a rear actuating transverse rod 4b and acts centrally on the adhesive fluid cartridge piston 2b over a small area, as indicated at 4c.
- Adhesive fluid cartridge actuating stamp 4 is slidably mounted for pressing the piston 2b in the direction of the arrow 7 towards the tip 3; As can be seen in FIG. 2, pistol-like pliers handles known per se can be used in addition to or instead of the manual actuating transverse rod 4b.
- the heating cartridge 5 is guided around the adhesive fluid cartridge in the form of a single heating winding.
- the arrangement around the adhesive fluid cartridge casing is designed such that the entire contents of the adhesive fluid cartridge are heated as uniformly as possible when the heating cartridge 5 is heated.
- the heating cartridge 5 is to be connected to an electrical power supply via a short connecting line 5b.
- a full adhesive fluid cartridge with adhesive fluid that is still solid is inserted into the adhesive fluid dispensing device 1 and the tip 3 is screwed on.
- the heating element 5 is connected via line 5b to an energy source and thus heats up to an operating temperature of, for example, 130 ° C.
- the adhesive fluid in the The adhesive fluid cartridge melts evenly from all sides without fear of local overheating.
- the line 5b can be disconnected from the power supply and the adhesive fluid dispensing device can be carried to a place of use.
- adhesive fluid can be pressed out of the tip 3 by manually actuating the adhesive fluid cartridge actuating stamp 4.
- the heating cartridge insulates the cartridge against heat loss and is therefore also an insulating agent.
- the temperature values determined on the adhesive fluid dispensing device after heating can be seen in FIG. 2. It can be seen that the temperatures at the
- Adhesive fluid dispenser are such that the hottest exposed location is the adhesive fluid dispenser tip. If necessary, additional insulation can be used to ensure that certain limit temperatures, such as those prescribed for occupational safety reasons, are not exceeded. Even then, however, nothing changes in the fact that the adhesive fluid dispensing tip 3 has a sufficiently high temperature for the adhesive fluid dispensing.
- the cartridge can be removed, any adhesive fluid still present can be removed from the tip 3 by inserting a cleaning cartridge, and the adhesive fluid dispenser 1 can be put aside until the next use.
