Definitions
- the invention relates to a metering system for applying a bead of a multi-component composite material to a component.
- the bead of the multi-component composite material runs along a trajectory which usually has sections with different curvatures. If the bead is applied in an essentially rectangular trajectory, for example, the trajectory has four straight sections, that is, sections with a curvature of zero, and four strongly curved sections, for example in the form of a circular arc.
- the components of the multi-component composite are mixed in a mixing chamber of a mixing head and applied to the component via an outlet opening.
- Dosing systems known from the prior art are designed to have a uniform dosing rate when applying a bead made of multi-component composite material to a component. If you want to obtain a predetermined thickness of the bead of the multi-component composite material at every point on the trajectory, i.e. a uniform cross-sectional area of the bead of the multi-component composite material, the metering rate of the metering system must be set in such a way that the predetermined thickness of the bead is guaranteed at those points which the exit opening travels through a section of the trajectory at a low speed due to the system.
- Multi-component composite materials are in irreconcilable contrast to one another along the trajectory.
- the object of the present invention is to provide a metering system which reduces the time it takes to apply a bead of multi-component composite material to a component.
- this object is achieved by a metering system for applying a bead

- a control unit which is set up for this purpose is to send a control signal comprising control information to the Output the metering pump in such a way that a metering rate of the multi-component composite material is set via the output opening of the mixing head on the basis of the control signal
- the control unit being set up to contain and / or receive information relating to a trajectory and / or a trajectory speed depending on the trajectory, along / with which the exit opening for applying the multi-component composite material is moved, and wherein the control unit is also set up to send separate control information to the metering pump for each section of the trajectory to which a different trajectory speed is assigned compared to at least one directly adjacent segment of the trajectory to be output in such a way that a cross-sectional area of the be
- the mixing of the components can be "dynamic”, i.e. using an active stirring element, "static”, i.e. by bringing the components together and without using an active stirring element, or "static-dynamic”, i.e. by rotating an additional mixing helix, through which at least one of the components enters the mixing chamber take place.
- a dynamic mixing head may be preferred because it is reproducible uniform mixing of the components can be achieved with a minimal mixing volume.
- Dosing rate should be understood to mean, in particular, a ratio of the discharge rate of the multi-component composite material to the discharge rate of the multi-component composite material from the outlet opening or, in other words, a discharge rate (e.g. in terms of volume and / or mass) per unit of time (e.g. per second).
- a discharge rate e.g. in terms of volume and / or mass
- the same metering rate can be achieved as with a high discharge rate and a low discharge speed.
- a metering rate can be increased if at least one of the discharge quantity and discharge speed is kept constant and the other (or both) is increased.
- cross-sectional area of the bead of the multi-component composite material is viewed in particular in a direction at right angles to the direction in which the bead of the multi-component composite material is applied to a component.
- a uniform cross-sectional area does not necessarily have to require a uniform cross-sectional shape, but this can be advantageous.
- the control unit can advantageously receive the information relating to a trajectory and / or a trajectory speed as a function of the trajectory from a CNC controller which is set up to control a drive which is set up to move the exit opening along the trajectory.
- a predetermined time for example 5 ms
- a delivery rate can be set and adapted accordingly on the basis of this compressibility of the basic component.
- the metering system according to the invention makes it possible to achieve a highly dynamic adaptation of the metering as a function of the trajectory.
- the exit opening can thus always be displaced at the maximum speed for a respective section of the trajectory or a respective curvature of the trajectory.
- the metering system according to the invention makes it possible to increase the metering capacity proportionally in sections with a higher speed of the outlet opening and to reduce it proportionally in sections with a lower speed of the outlet opening, so that the cross-sectional area of the bead of the multi-component composite material along the entire trajectory to which the multi-component composite material is applied , remains essentially constant.
- the close arrangement of the metering pump relative to the outlet opening of the mixing head enables a significantly more dynamic, and thus faster, adjustment of the metering output.
- dynamic losses due to the elasticity of line walls or due to the compressibility of the multi-component composite material or its components can be reduced or even avoided.
- this dynamic adjustment of the dosing rate can be achieved in connection with highly dynamic control technology, which is set up to carry out a precalculation of a path speed, a discharge quantity and / or a discharge speed in the range of 1 - 128 ms and to output corresponding control information to the dosing pump.
- the supply pump of the respective component can, at least can be operated continuously during the application of the multi-component composite material or can only be switched between an ON state with a predetermined delivery rate and an OFF state.
- the supply pumps can also be operated with speed control, so that it can be ensured that a pump input pressure at the metering pumps is constant regardless of the consumption. Therefore, the following description will mainly refer to a control of the metering pump, although the description can of course also be used to control the supply pump.
- the outlet opening of the mixing head can be designed as a section of the mixing chamber or connected to the mixing chamber via a line.
- the mixing head can thus have an opening through which the multi-component composite material can be applied directly to the component.
- the outlet opening can be connected via the line to an opening of the mixing head via which the multi-component composite material leaves the mixing chamber.
- the line between the outlet opening and the mixing chamber of the mixing head can be designed as a tube or as a hose line.
- the line in the event that the line is designed as a hose line, it may be possible to move only the outlet opening of the hose line along the trajectory and not move the mixing head relative to the component or in particular along a simplified, for example circular or rectangular, trajectory to move.
- the metering system can be set up to open the outlet opening for applying the multi-component composite material with a Moving speed from 1 m / min to 100 m / min, in particular from 3 m / min to 60 m / min. In this way, both sections with narrow radii of curvature and sections with a straight path curve can be traversed at maximum speeds in each case.
- the control unit can be set up to output separate control information in separate control signals to the dosing pump for each trajectory section with a uniform trajectory speed and / or to output a plurality of separate control information for each trajectory segment with a uniform trajectory speed in at least one control signal together to the dosing pump.
- respective control information which includes, for example, instructions to the dosing pump as to the power with which the dosing pump is to work, can be output in a separate control signal each time the content of the control information, i.e. the instructions to the dosing pump, change or a single control signal can comprise a plurality of control information items.
- the control information also includes a period of time over which the metering pump is to be operated with a predetermined output.
- the trajectory which includes different trajectory speeds, can be designed as a closed ring.
- the bead of the multi-component composite material can be applied along an edge of a component, such as a windshield, for example, in order to glue it to a frame.
- a component such as a windshield
- the trajectory is designed as a closed ring, penetration of liquid or foreign bodies from outside the closed ring can be prevented.
- such a ring does not have to be circular, but can, for example, be approximately rectangular as a sequence of straight sections and circular arc sections.
- the multi-component composite material can be an adhesive or sealant comprising two or more components, in particular an adhesive foam or sealing foam, which preferably comprises polyurethane or silicone.
- an adhesive foam or sealing foam which preferably comprises polyurethane or silicone.
- a typical example of this can be a so-called FIPFG seal.
- two pump groups can be arranged accordingly.
- the present invention can enable the supply pumps to provide a "basic supply" of components to the mixing head and the metering pumps to introduce components into the mixing head with high precision and speed, even foams with a path-dependent control , for example based on a CNC control, and to apply a constant cross-section.
- the metering system in particular the metering pump, can be set up to discharge the multi-component composite material in a power range of 0.1 cm 3 / s to 20 cm 3 / s. This makes it possible to apply sufficient multi-component composite material to the component even in sections of the trajectory in which the exit opening is moved at high speed along the component in order to be able to ensure the uniform bead thickness of the multi-component composite material.
- control unit can also be set up to assign a uniform path speed and / or uniform control information for the metering pump for setting the discharge of the multi-component composite material to coherent sections of the trajectory that have a constant curvature.
- a uniform path speed for moving the outlet opening and thus a uniform metering rate of the metering pump can be assigned, which can be output to the metering pump as a control signal comprising control information.
- an acceleration or a deceleration of the exit opening at the beginning or at the end of a respective contiguous section can of course be taken into account.
- the present object is achieved by a method for evenly applying a bead of a multi-component composite material to a component, the method providing a mixing head which, for each component of the multi-component composite material, has a feed line from a source of the respective component to a mixing chamber of the Has mixing head, which is set up to mix the individual components of the multi-component composite material in the mixing chamber, and which has an outlet opening through which the mixed multi-component composite material leaves the mixing head, providing a metering pump which is set up to discharge the multi-component composite material through the outlet opening of the mixing head, and providing a control unit, which outputs a control signal comprising control information to the metering pump in such a way that a metering track processing of the multi-component composite material is set via the output opening of the mixing head on the basis of the control signal, wherein the Control unit contains and / or receives information relating to a trajectory and / or a trajectory speed as a function of the trajectory
- the method according to the invention can include that the metering system can move the exit opening for applying the multi-component composite material at a speed of 1 m / min to 100 m / min, in particular 3 m / min to 60 m / min. This can be a rapid traversal of the exit opening of sections with little curvature and an adapted traversal of sections with allow strong curvature.
- control unit can output separate control information in separate control signals to the metering pump for each trajectory section with a uniform trajectory speed and / or output a plurality of separate control information for each trajectory segment with a uniform trajectory speed in at least one control signal together to the dosing pump.
- control information relating to different dosing rates can be combined in control signals along individual sections.
- the metering system in particular the metering pump, can discharge the multi-component composite material in a performance range from 0.1 cm3 / s to 20 cm3 / s.
- the dosing output of the dosing pump can be adapted to the speed of movement of the exit opening along the trajectory.
- control unit can assign a uniform path speed and / or uniform control information to contiguous sections of the trajectory which have a constant curvature, so that the metering pump leaves the discharge of the multi-component composite material unchanged over a respective contiguous section.
- This can also contribute to reducing the processing outlay for controlling the metering system.
- the control unit cannot output any control information to the metering pump as long as the outlet opening is moved through a trajectory section with a constant curvature.
- the metering system can further comprise an air conditioning device which is set up to control the temperature of at least one of the components of the multi-component composite material, that is to say to cool or heat it.
- Figure 1 is a side view of an embodiment of the device according to the invention.
- FIG. 2 shows a plan view of the device from FIG. 1;
- FIG. 4 shows a plan view of the metering system according to the invention
- FIG. 5 shows a side cross-sectional view of a dynamic mixing head of the dosing system according to the invention.
- FIG. 6 shows a perspective view of a container frame of the device according to the invention.
- a metering system according to the invention is generally designated by the reference number 10.
- the metering system 10 comprises a mixing head 12 in which components of a multi-component composite material are mixed with one another in a mixing chamber 14.
- the multi-component composite material is applied to a component from the mixing head 12 via an outlet opening 16.
- the outlet opening 16 is connected to the mixing chamber 14 via a tubular outlet nozzle 18.
- the components of the multi-component composite material are conveyed via four metering pumps 20, 22, 24, 26 from component sources (not shown) to the mixing chamber and from there to the outlet opening 16.
- a control unit 28 in data communication with the metering pumps 20, 22, 24, 26 supplies the metering pumps 20, 22, 24, 26 with control information, on the basis of which the respective metering outputs of the metering pumps 20, 22, 24, 26 are set.
- how much volume and / or mass is conveyed per second by a respective metering pump 20, 22, 24, 26 can be regarded as the metering rate.
- the dosing system 10 is viewed vertically from above and it can be seen that the outlet opening 16 (shown covered in FIG. 2 by components above it) is moved along a trajectory 30 on which the multi-component composite material is to be applied to a component 32 .
- the trajectory 30 comprises a first section 30_1, which runs essentially in a straight line, a second section 30_2, which has a 90 ° curve, and a third section 30_3, which in turn runs essentially in a straight line.
- a drive 34 is set up to move the outlet opening 16 along the trajectory 30. Since, like every drive, the drive 34 also needs a certain time or a certain distance to accelerate the exit opening 16, it is obvious that in the first section 30_1 and the third section 30_3 of the trajectory 30 higher displacement speeds of the exit opening 16 can be achieved than in the second section 30_2, in which the outlet opening 16 must pass through the 90 ° curve.
- control unit 28 for example from a CNC control unit (not shown), receives information on the trajectory 30 and the trajectory speeds of the exit opening 16 that can be realized there by the drive 34, the control unit 28 can send control information to the metering pumps in relation to a corresponding section of the trajectory 30 20, 22, 24, 26 output in such a way that, despite varying web speeds of the exit opening 16, the same amount of multi-component composite material is always applied per unit of travel (for example, viewed on a web section with a length of 5 cm).
- FIGS. 3a to 3d show longitudinal sections of beads 36, 38, 40, 42 of a multi-component composite material, the longitudinal sections having been taken, for example, along a plane which is essentially parallel to a plane of the sheet in FIG.
- the arrows in FIGS. 3a to 3d indicate the direction along which the respective bead 36, 38, 40, 42 of the multi-component composite material has been applied.
- FIG. 3a shows a caterpillar 36 which has been created with a conventional metering system of the prior art. That is, the bead 36 was applied with a constant movement speed of an outlet opening and a constant metering rate of a metering pump.
- the sections 36_1, 36_2 and 36_3 have an essentially uniform bead thickness.
- FIG. 3b clearly illustrates the problem that occurs when a known metering system is modified only to the effect that the outlet opening 16 is displaced in straight sections of the trajectory 30 at a higher speed than in curved sections of the trajectory 30.
- the dosing output of the Dosing system remains constant. It can be seen in FIG. 3b that the thickness of the bead 38 in an area 38_1, in which the exit opening 16 is delayed in order to subsequently pass through the curved area 38_2, first increases and then reaches the thickness which corresponds to the speed of the exit opening 16 corresponds with which the section 38_2 is run through. In a section 38_3, which is located downstream of the curved section 38_2, the exit opening 16 is accelerated again, so that the thickness of the bead 38 decreases accordingly.
- FIG. 3c now shows a further undesired result of applying a bead 40 made of multi-component composite material to a component.
- the speed at which the exit opening 16 is displaced is adjusted based on the curvatures of the sections 40_1, 40_2 and 40_3, but the
- the metering rate of a metering pump or metering pumps 20, 22, 24, 26 is not controlled proportionally to the speed of the displacement of the outlet opening 16. As a consequence of this, the metering pump decelerates or accelerates too much, so that a thickness of the bead 40 decreases in the section 40_1 towards the section 40_2, increases again in the section 40_2 towards the beginning of the section 40_3 and then again in the course of the section 40_3 decreases.
- FIG. 3d now shows the result of applying a bead 42 of a multi-component composite material based on the present invention.
- a bead 42 When applying the bead 42, both a movement speed of the outlet opening 16 is varied and a metering rate of the metering pumps 20, 22, 24, 26 is controlled proportionally to the movement speed of the outlet opening 16.
- a bead 42 can be generated which has a constant thickness over the sections 42_1, 42_2 and 42_3, that is to say one in planes at right angles to the plane of the sheet in FIG. 3d and at right angles to a
- the direction of application of the bead 42 has a constant cross-sectional area.
- FIG. 4 shows the metering system 10 in a top view.
- the mixing head 12 can be seen from above in a manner analogous to FIG.
- First and second metering pumps 22, 24 are arranged on both sides of the mixing head 12, whereby here, as an example, the first metering pump 22 is to be assigned to the first component A and the second metering pump 24 to be assigned to the second component B.
- a first component container 44 of the first component A and a second component container 46 of the second component B can be seen, which are designed here as barrels and are interchangeably connected to the metering system 10.
- the component containers 44 and 46 are each fluidically coupled to a supply pump 48, 50, with the supply pump 48 taking the first component A from the first component container 44 and the supply pump 50 the second component B from the second component container 46 via lines, not shown, to the mixing head 12 promotes.
- the supply pumps 48, 50 are operated continuously or with speed control, so that the components are supplied to the mixing head and a predetermined excess pressure is maintained in the supply lines.
- the metering system 10 here also comprises an air conditioning device 52 which is set up to control the temperature of at least one of the components A and B, that is to say to cool or heat them.
- a flushing device 54 for emptying and / or cleaning the mixing head 12 and a scale 56 are also shown in FIG.
- the mixing head 12 is enlarged Side cross-sectional view shown. It can be seen here that the mixing head 12 is designed as a dynamic mixing head in this embodiment. That is, in the mixing chamber 14 there is a stirring element 58 which rotates about the vertical axis within the mixing chamber 14 (an axis from top to bottom in FIG. 5).
- the stirring element 58 has depressions 60 on its outer circumference in order to be able to improve a stirring effect of the stirring element 58.
- components introduced into the mixing chamber 14, for example components A and B, can be mixed very homogeneously.
- the mixed components leave the mixing chamber 14 via the tubular outlet nozzle 18 and are then applied to a workpiece via the outlet opening 16.
- a container frame 62 which serves to accommodate, among other things, the first (not shown) and second component containers 46 and the respective supply pumps 48, 50 and the air conditioning device 52.
- the component containers are arranged above the supply pumps 48, 50, so that the components A and B can be provided to the supply pumps 48, 50 with the aid of gravity.
- the elevated arrangement of the component containers facilitates their replacement, for example using a forklift.
