Definitions

  • the invention relates to an application system for depositing an adhesive bead made of a curable adhesive material onto a surface, the application system having a nozzle holder with a nozzle head, and a connecting device for connecting a reservoir supply line to the nozzle holder, the adhesive material being made from an adhesive material reservoir when the application system is used as intended is guided through the reservoir supply line to the nozzle holder, with the adhesive material emerging from the nozzle holder through the nozzle head.
  • an adhesive bead made of a curable adhesive material can be placed on a surface by hand or with the help of a suitable application system.
  • the second component to be connected to the first component can be brought into contact with the first component in the area of the adhesive bead, with the adhesive material hardening over time and adhesively connecting the two components to one another.
  • application systems In the field of window construction, automated application systems are usually used, which independently place a bead of adhesive on a previously specified surface can.
  • application systems from the prior art have a nozzle holder provided with a nozzle head, which is connected to a reservoir supply line using a connecting device.
  • the reservoir feed line is designed to guide the adhesive material from an adhesive reservoir to the nozzle holder and finally to the nozzle head.
  • the reservoir feed line is also set up so that the different phases are mixed within the reservoir feed line and are ultimately present as a homogeneous mixture.
  • the nozzle holder and the nozzle form part of a flow channel from the adhesive material reservoir to the nozzle head, so that the adhesive material flowing from the adhesive reservoir flows through the nozzle holder and can exit the nozzle head.
  • the adhesive material can harden within the nozzle holder and the nozzle head or even within the reservoir supply line, whereby the flow of the adhesive material is disrupted or even comes to a complete standstill.
  • the same problem occurs if there is a longer break between the individual adhesive beads deposited, which occurs, for example, when a component is changed or when the application system stops overnight or during a repair or maintenance phase.
  • the reservoir supply line as well as the nozzle holder and the nozzle head are designed as a disposable product and are replaced and disposed of at the end of a work cycle.
  • the object of the invention is therefore to improve the application system known from the prior art.
  • the application system has a nozzle supply line connecting the connecting device to the nozzle head, so that when the application system is used as intended, the adhesive material is guided through the nozzle supply line from the reservoir supply line to the nozzle head, avoiding direct contact of the adhesive material with the nozzle holder .
  • the design according to the invention makes it possible for the nozzle holder not to be designed as a disposable product and not to have to be disposed of after the adhesive material has hardened. Rather, the nozzle holder can be reused several times.
  • the adhesive material is not guided along the flow channel from the reservoir supply line through the nozzle holder to the nozzle head, but rather the adhesive material can flow from the reservoir supply line to the nozzle head, bypassing the nozzle holder. In the event of unwanted hardening of the adhesive material or if the application system is stationary for long periods and the flow of adhesive material through the nozzle supply line is impaired, it can simply be removed and replaced, while the nozzle holder does not have to be replaced.
  • the nozzle supply line suitable for this can be arranged at a distance from or on a surface of the nozzle holder.
  • the nozzle supply line as well as the reservoir supply line can be made from a commercially available hose, which means that the costs of this replacement part can be kept as low as possible.
  • the nozzle supply line can be arranged on the reservoir supply line using the connecting device and connected to it in a fluid-carrying manner.
  • the nozzle supply line is formed completely or at least partially from the reservoir supply line, which can simplify the replacement of the parts to be replaced.
  • the connecting device itself can connect the reservoir supply line and the nozzle supply line with one another.
  • the connecting device can connect the reservoir feed line and the nozzle feed line to one another via their end faces, with a configuration of the connecting device also being possible in which the adhesive material flows from the reservoir feed line first into the connecting device and then into the nozzle feed line.
  • the nozzle supply line can also be arranged within the nozzle holder and run in it. Therefore, in a further advantageous embodiment of the invention, it is provided that the nozzle supply line is arranged in a recess that completely penetrates the nozzle holder.
  • the recess in the nozzle holder can be used as a separate nozzle holder, for example in a longitudinal direction completely penetrating recess, the recess of the nozzle holder being in particular the recess that guides the adhesive material of the nozzle holder, which is already provided and created in commercially available nozzle holders.
  • nozzle holders when arranging the nozzle supply line in this already provided recess, commercially available nozzle holders that are not manufactured separately for the purpose according to the invention can be used, which in turn can save costs.
  • the nozzle holder can therefore preferably be arranged along the flow channel in the nozzle holder.
  • the recess can be adapted to the nozzle supply line.
  • an inner diameter of the recess of the nozzle holder is adapted to an outer diameter of the nozzle supply line.
  • the nozzle supply line therefore advantageously rests with a peripheral surface on the inner wall of the recess.
  • the nozzle feed line can also have a slightly larger outer diameter, whereby with an elastic design of the nozzle feed line, the nozzle feed line can be fixed in the recess in a clamping manner. This can prevent the nozzle supply line from accidentally slipping out.
  • a rotation-proof arrangement of the nozzle supply line in the recess can also be achieved through the geometric design of the nozzle supply line and the recess.
  • the nozzle supply line can be designed with a triangular or higher polygonal cross section and can therefore be arranged in a rotationally secure manner in a rectangular or square recess.
  • the invention provides that the nozzle supply line is detachably arranged in the recess.
  • the nozzle supply line is simply pushed into the recess and is held there in a non-positive manner.
  • the nozzle supply line is designed to be hollow cylindrical.
  • the nozzle supply line can be a commercially available plastic hose.
  • the nozzle supply line is used exclusively to supply the adhesive material to the nozzle head. Therefore, according to the invention, the nozzle feed line is empty as long as no adhesive material is passed through the nozzle feed line to the nozzle head and is completely filled with adhesive material when the adhesive material is passed to the nozzle head. Any mixing devices or the like can also be used in the application system, but are then basically provided as separate components that are arranged at a distance from the nozzle line and are fluidly connected to the nozzle supply line.
  • the nozzle feed line has a nozzle head receiving area for connecting the nozzle feed line to the nozzle head and a connecting device area arranged at a distance from the nozzle head receiving area for connecting the nozzle feed line to the connecting device.
  • the nozzle feed line can each have an area at opposite ends which is suitable for connection to the nozzle head and for connection to the connecting device.
  • the design of these two areas, the nozzle head receiving area and the connecting device area can be designed in the same way or have a different design than the respective other area.
  • One possible embodiment includes the design of these areas with a thread, so that the nozzle feed line with this thread can engage in a counter-thread of the nozzle head or the connecting device and can be fixed to it in a fluid-conducting manner. Furthermore, a clamping or fixing by means of a pressure element such as a screw or a stamp or even a bayonet connection is also considered. The connection can preferably be made without tools.
  • the connecting device region of the nozzle supply line protrudes from the recess of the nozzle holder when arranged in accordance with the intended purpose in the recess of the nozzle holder, so that the nozzle supply line can be connected to the connecting device in a simple manner.
  • the nozzle supply line can preferably protrude so far out of the recess in the nozzle holder that the connecting device area set up for connection to the connecting device protrudes completely out of the recess. This enables the connection to be as simple and uncomplicated as possible.
  • the nozzle head is detachably attachable to the nozzle holder. This enables the nozzle head and thus the deposited adhesive bead to be quickly adapted to the work currently being carried out and the nozzle head to be easily replaced when the adhesive in the nozzle head has hardened. In this way, the nozzle head and the nozzle supply line can easily be replaced at the same time.
  • the nozzle head can, for example, engage with a locking mechanism in a counterpart of the nozzle holder provided for this purpose and can be secured to it.
  • a locking mechanism in a counterpart of the nozzle holder provided for this purpose and can be secured to it.
  • other fixing methods are also possible, such as a bayonet connection, in which an engagement element of the nozzle head can engage in a recess in the nozzle holder, with fixing being possible when the two parts rotate relative to one another.
  • the nozzle head can be fixed to the nozzle holder in a clamping manner.
  • the nozzle head can engage with an engagement element in a recess in the nozzle holder and be clamped therein.
  • the engagement element of the nozzle head can particularly advantageously engage in the recess of the nozzle holder for fixing purposes.
  • the nozzle supply line is designed to be rigid in the longitudinal direction of the nozzle supply line.
  • the nozzle supply line can be designed as a hose made of a dimensionally stable plastic such as PVC or other types of plastic.
  • the nozzle supply line can also be made from a flexible composite material.
  • the nozzle feed line has such a rigidity that the nozzle feed line and in particular the connecting device area of the nozzle feed line is arranged in a simple manner on the connecting device and can be fixed to it and, on the other hand, the rigidity can be designed such that a dimensionally stable nozzle feed line is maintained.
  • the recess in the nozzle holder runs along the longitudinal direction of the nozzle holder, with the recess completely penetrating the nozzle holder.
  • the nozzle head can be attached to one end of the nozzle holder and fixed in a clamping manner with an engagement element, whereby the nozzle supply line can be inserted into the recess of the nozzle holder from a side facing away from the nozzle head until the nozzle supply line in the recess rests on the engagement element of the nozzle head.
  • an engagement element of the nozzle head can be inserted into the recess of the nozzle holder, or the engagement element surrounds the nozzle holder on a peripheral surface of the nozzle holder and rests against it in a clamping manner.
  • the engagement element of the nozzle head engages in the recess of the nozzle holder in such a way that the nozzle supply line can be pushed into the nozzle head and does not just rest against it.
  • the nozzle feed line can further be designed in such a way that the nozzle feed line is preferably clamped together with the pressure in the longitudinal direction of the nozzle feed line
  • the specified nozzle head can be removed from the nozzle holder. This enables the disposable components to be easily replaced without the need for tools for removal.
  • the nozzle head has a plurality of nozzle recesses through which the adhesive material can emerge from the nozzle head.
  • the nozzle head can have one or more nozzle recesses.
  • the nozzle recesses can be arranged next to one another or in a geometric pattern relative to one another. By using several nozzle recesses, a geometrically complex adhesive bead or even several adhesive beads next to each other can be achieved. Due to the interchangeable design of the nozzle head, the deposited adhesive bead can be adapted to the desired shape at any time by simply changing the nozzle head.
  • the nozzle head prefferably has a nozzle lip arranged on the nozzle head.
  • the nozzle lip can be arranged on the nozzle head and its shape can influence the geometry of the deposited adhesive bead. This also includes, for example, the fact that particularly straight edges of the adhesive bead are made possible in this way.
  • FIG. 1 and 2 a schematic representation of an embodiment of the application system according to the invention is shown.
  • the design according to the invention makes it possible for the nozzle holder not to have to be disposed of as a disposable product after the adhesive material has hardened, as provided in the prior art, but rather can be reused multiple times.
  • the adhesive material is not guided along a flow channel from the reservoir supply line through the nozzle holder to the nozzle head, but rather the adhesive material can flow from the reservoir supply line to the nozzle head, bypassing the nozzle holder.
  • the application system 1 has an elongated and essentially rectangular nozzle holder 2 with a nozzle head 3.
  • a nozzle supply line 5 in the form of a hose is arranged in a recess 4 penetrating the nozzle holder 2 in a longitudinal direction.
  • the nozzle feed line 5 has a nozzle head receiving area 6 at a first end of the nozzle feed line 5 and a connecting device area 7 at another end opposite the first end.
  • the nozzle supply line 5 is arranged on the nozzle head 5 with the nozzle head receiving area 6, while the nozzle supply line 5 is connected to the connecting device area 7 in a fluid-conducting manner with a connecting device 8.
  • the nozzle feed line 5 is designed in such a way that the connecting device region 7 of the nozzle feed line 5 protrudes completely from the recess 4 of the nozzle holder 2 in order to be able to be easily inserted into the connecting device 8.
  • the nozzle holder 2 is connected to the connecting device 8 via a bayonet-like connection at an end facing away from the nozzle head 3.
  • the connecting device area 7 of the nozzle supply line 5 engages in the connecting device 8.
  • the Application system 1 is shown in an assembled state in which the nozzle supply line 5 as well as the nozzle holder 2 are connected to the connecting device 8
  • the nozzle holder 2 is in Figure 2 shown separated from the connecting device 8 in an unassembled state.
  • the connecting device 8 itself is further connected to an adhesive material reservoir, not shown in the figures, via a reservoir supply line 9 designed as a hose.
  • the adhesive material reservoir, the reservoir supply line 9, the nozzle supply line 5 and the nozzle head 3 are connected to one another in a fluid-conducting manner along a flow channel.
  • adhesive material flows via the reservoir supply line 9 from the reservoir supply line 9 via the nozzle supply line 5 into the nozzle head 3, the adhesive material emerging from nozzle recesses 10 of the nozzle head 3 and can be applied to a surface in the form of an adhesive bead.
  • the Figure 3 shows a section of the nozzle holder 2 Figure 3 along section line III-III.
  • the elongated recess 4 of the nozzle holder 2 which penetrates the nozzle holder 2 in the longitudinal direction, can be seen, in which the nozzle supply line 5 is fixed in a clamping manner.
  • the nozzle head 3 is also arranged in a clamping manner on the nozzle holder 2 with an engagement element and forms an extension of the recess 4, so that the nozzle supply line 5 protrudes into the nozzle head 3.
  • the Figures 4 to 6 show further alternative design options for the nozzle holder 2 and the Nozzle head 3rd in Figure 4
  • the engagement element of the nozzle head 3 engages in the recess 4 of the nozzle holder 2 and is clamped therein.
  • the nozzle supply line 5 rests on the engagement elements of the nozzle head 2.
  • the engagement elements engage Figure 5 also into the recess 4, but the recess 4 is designed so that the nozzle supply line 5 can be inserted into the nozzle head 3.
  • the engagement element of the nozzle head 3 surrounds the nozzle holder 2 on a peripheral surface.
  • Figure 7 shows an example of an exploded view of the nozzle holder 2 Figure 3 .
  • the Figures 8 and 9 each show a nozzle holder 2 with a nozzle head 3 and a nozzle feed line 5, with adhesive material 11 being hardened in the nozzle feed line 5 and the nozzle head 3.
  • the composite of the nozzle holder 2, nozzle head 3 and nozzle feed line 5 can be tapped onto a surface with the connecting device area 7 along the longitudinal direction 12 of the nozzle holder 2, with the nozzle feed line 5 and the Detach nozzle head 3 from nozzle holder 2.
