- Such a "caulking gun” * is known from WO 2005/077548
- Devices of this type are used, for example, in the installation and in the Kfe craft for applying adhesive, grout or sealant, e.g. Silicone rubber, in the form of a strand that is as uniform as possible (“bead”) .
- the housing, the cylinder is connected on the pressure side, ie on the side of the piston remote from the pasty mass, via a hose to an external pressure source from which the pressure medium is introduced.
- the pressure source is integrated in the form of an electrically driven compressor in the device, the compressor from the network or, as in the known caulking gun, is fed by a battery.
- Devices of this type should be as light and handy, especially compact built. In addition, they should be easy and targeted control. This means that the mass flow should flow as evenly as possible, but it should also be able to accelerate and slow down quickly or be stopped altogether quickly. Both requirements are not satisfactorily solved in the known device.
- DE 41 34 141 C2 discloses a device for dispensing a pasty mass ("compressed-air pistol for applying pasty material"), in which a piston arrangement consists of two sub-pistons telescopically extendable and retractable one after the other When the end position is reached, the other one comes into action and continues to press on the mass to be ejected.
- the purpose of this construction is to keep the necessary length of the pistol as short as possible, so that targeted, sensitive control of the mass flow is not possible.
- the invention has for its object to provide a compact, in particular short device for dispensing a pasty mass, which adapt to the processing of packaged in cartridges and film bags material and can be controlled in a targeted and accurate with just a few simple steps.
- the device according to the invention for dispensing a pasty mass from a cartridge or a foil bag has a tubular housing in which a piston which can be acted upon by a pressure medium is movable, which acts on the pasty mass to be accommodated in the housing in front of the piston in the cartridge or in the foil bag.
- the piston carries an element which, under the action of the pressure medium, can be extended axially in the direction of the mass to be applied.
- the extendable element consists of a balloon inflatable by the pressure medium.
- a central bore is provided and fixed in the bore a pipe on which the Huaweiden material facing end ("working side") is mounted on the pressure medium expandable balloon.
- the extendable element consists of a telescopic piston arrangement arranged on the working side of the piston.
- a telescopic piston assembly of at least two telescopically arranged in each other, mounted on the pipe and against each other axially displaceable part piston, wherein upon exposure to the pressure medium, first the piston together with the telescopic piston assembly and upon reaching a certain end position of the pasty mass acting on the sub-piston is moved further and finally tows the other in the extended position.
- the outer sub-piston is designed as a trailing Operakotben and arranged adjacent to the receiving space for the pasty mass.
- the pressure medium acts on the maximum possible surface over the entire working length of the sub-piston the piston assembly. That is, the available pressure is optimally used over the entire movement distance and the force acting on the mass to be applied remains constant at constant pressure. In this way, the mass flow can be controlled very well.
- Fig. 2 in section a second embodiment of the functional part
- Fig. 3a, 3b, 3c, 3d in section and in exploded view of a piston, a telescopic piston assembly or a cartridge housing and collar sleeve or foil bag.
- Fig. 1 shows the functional part 10 and the control part 70 of a caulking gun, which are housed in the manner of a hand drill in a common housing.
- the functional part 10 consists of a cylindrical housing 12 which is closed on the pressure side by an upper coupling nut 16 provided with a connecting nipple 14. The opposite end of the housing 12 is closed by means of a union nut 18, which is provided with a central bore 20.
- a piston 22 with a rigidly attached thereto, e.g. in this screwed guide tube 24.
- a first, inner partial piston 26 is slidably mounted in the axial direction, on which in turn a second, outer partial piston 28 is displaceable.
- the outer part piston 28 is closed by a bottom 30.
- an inwardly projecting flange 32 is formed at the right in the drawing right end of the first and second part pistons 26 and 28 respectively.
- an outwardly projecting flange 34 is formed in each case.
- the piston 22 is sealed by a ring seal 36 against the inner wall of the housing 12.
- the partial pistons 26, 28 are thus telescopically displaceable relative to each other and relative to the guide tube 24, wherein the flanges 34 each as a stop for the flanges 32nd and the outer sub-piston 28 as a dragging and the inner sub-piston 26 act as a towed piston.
- the spout 37 of the cartridge 38 protrudes through the bore 20 in the union nut 18 to the outside.
- the control part 70 consists essentially of a compressor 72 which is driven by a crank motor 74 by a battery motor 76.
- a switch 78 For switching on and off the accumulator motor 76 is a switch 78.
- a pivotable about an axis 81 shift handle 80 is connected via a switching rod 82 to the switch 78.
- the Schaher 78 can be switched on and off by pressure on the shift rod 82 alternately.
- the shift handle 80 acts on a switching rod 84 further on a path-dependent controllable valve 88. Depending on how deep the racking rod 84 is depressed by means of the control handle 80, 88 more or less pressure can be discharged by means of the valve. If the shift rod 84 completely pushed, it comes to the complete venting of the system.
- valve 88 The simplest example of such a valve is the usual valve of a car tire.
- the maximum achievable pressure can be adjusted by means of a pressure actuator 90 and read using a pressure gauge 92.
- the compressor 72 and the valve 88 on the one hand and the valve 88 and the connection nipple 14 of the functional part 50 on the other hand are each connected to one another via a pressure hose 74.
- the cap nut 18 is unscrewed and the cartridge 38 is inserted with the free or rear end ahead in the housing 12.
- the partial pistons 26, 28 and the guide rod 24 are pushed into each other until the piston 22 rests against the inside of the union nut 16.
- the housing 12 is closed again with the union nut 18.
- the cartridge gun is ready for use, with the piston 22 and telescopic piston assembly 26, 28 are first completely pushed together.
- the piston apparatus moves to the left until the bottom 30 of the telescopic piston 28 rests against the bottom or piston 39 of the cartridge 38 on the one hand and the bottom of the piston 22 on the other hand against the bottom of the union nut 16.
- the entire piston assembly moves in the drawing to the left and pushes pasty mass from the spout 37 until the working side edge of the cylindrical piston 22 rests against the edge of the cylindrical cartridge 38.
- Fig.l moves on further pressure supply to next to the sub-piston 28 and finally takes the sub-piston 26 with it, until all the material is squeezed out of the cartridge 38.
- Fig. 2 shows a second embodiment of the device according to the invention, in which the element for extending the piston 22 consists of a piston 44 attached to the piston.
- the piston 22 carries a pipe 24 penetrating this, on whose end protruding from the piston, that is to say on the working side, an intermediate sleeve 40 is attached. On this intermediate sleeve 40 sits an outer sleeve 42 with a support flange 43. Between the two sleeves 40, 42 of the balloon 44 is attached. Since the balloon 44 in the relaxed state requires little length, the design-related length is particularly small here.
- the cap nut 18 is unscrewed to load the cartridge gun, the cartridge 38 is inserted and pressed together with the piston 22 and balloon 44 in the direction of sleeve 16. Then the caulking gun is closed again.
- the balloon 44 fills and pushes the piston 22 against the bottom of the cartridge gun, ie against the bottom of the sleeve 16.
- the piston 22 shifts to the left until it, as shown in FIG. 2, the lower edge of the cartridge shell 38 is reached.
- the balloon 44 is stretched more and more, and he pushes the piston 39 of the cartridge 38 further to the left until the research document mass is completely pressed out of the cartridge 38 out.
- a collar or spring washer should be placed on the piston head 30, the collar of which resting against the housing wall prevents penetration of the film between the housing 12 and the partial piston 28.
- Fig. 3a shows together with Figure 3b, 3c on the one hand and with 3d, 3e on the other hand, that only a minor modification is required to use a cartridge or a foil bag.
- Fig. 3a shows in section a piston 22 with an attached pipe 46.
- Fig.3b shows the section of a telescopic piston assembly 24, 26, 28,
- Fig. 3c is a partial section of a cartridge 38 with the cartridge bottom 39. Together these are the essential Components of the functional part 10 of FIG. 1. If the cartridge gun to be adapted to the use of a foil bag, the telescopic piston assembly 24, 26, 28 is replaced by a support flange 48 with a collar plate 50.
- the union nut 18 with spout 37 by a union nut with molded spout (not shown) to replace.
- the spray gun can be switched on and off by pressure on the shift rod 82.
- the pressure is built up by means of the compressor 72 until the pressure set on the pressure regulator 90 has been reached.
- the compressor 72 then turns off and on reaching a set pressure on the pressure plate 90 again. If you let go of the switch handle 80, the pressure in the system is maintained. With the help of an additional button (not shown) can be switched to continuous operation. Pressing with the aid of the control handle 80 on the shift rod 84, so if released, the lock releases, and the pressure is released depending on the depth of penetration of the shift rod 84 into the valve 88 slowly or faster. Accordingly, the mass flow is slowed down less or more. When releasing the shadow rod 84, the residual pressure is maintained, so that the pressure is immediately available when switching on again. Pressing the shift rod 84 until it stops, the system is completely vented.
- the mass flow can thus be dosed by more or less strong pressure on the shift rod 84 simply and accurately and stop completely and immediately if necessary by fully pressing the shift rod 84 into the valve 88.
