Definitions

  • the present invention relates to a device for dispensing Fluids, especially flowable glue on a relative to the device movable substrate, with at least one application module, which one with a Fluid source connectable nozzle arrangement with a fluid channel and Has outlet opening through which fluid can be dispensed.
  • Devices for applying fluids such as hot melt adhesives, lacquers or other plastics on substrates movable relative to the device, such as for example, paper or body parts of vehicles are known and are used to deliver fluids and are flat, caterpillar-shaped or in other application forms continuously or intermittently on the substrate apply.
  • Such devices often referred to as application heads, come in various industries used in complex systems that are a fluid source approximately in the form of a container, a pump for conveying the fluid, a Heat transfer device for tempering the fluid, a Funding facility for
  • Moving the substrate relative to the application head for example in the form of a Conveyor belt and a control device for controlling and regulating the individual components included.
  • a device installed at the operator often has to adapt to changing applications be adjusted. It is often necessary to change the position of the Order module, namely the outlet for releasing the fluid relative to vary to the substrate.
  • Known devices have for this purpose Fastening devices with screw connections, with which the entire Application head in different positions on a fixed frame or the like can be fixed. These fasteners are relatively complex and require a lot of time Adapt to a new operating condition.
  • the US patent Re. 27,865 known device becomes a Varying the position of an order module, particularly the exit opening of an order module in that the order module can be pivoted stored on the base body and in various pivot positions is fixable. Due to the pivotable mounting of the application module on the The body can change the position of the Exit opening of the application module relative to a movable substrate can be changed without the entire order module and the entire Application head or a conveyor for a substrate in its position would have to be changed.
  • the order module is about a horizontal axis pivoted and fixed in a desired pivot position. On Swiveling the order module can during an interruption of the Apply fluid or even while applying fluid.
  • a disadvantage of the known device is that by pivoting of the application module, the angle of the outlet channel and the Exit opening changes relative to the substrate. This flows when swiveled Application module with respect to a vertical position, the fluid at an angle out of the outlet opening and also meets with such an angle, which as Impact angle can be referred to the substrate. The bigger the Impact angle is, the greater the influence on what is generated on the substrate Order samples, for example an adhesive bead. The caterpillar can high impact angles do not have a uniform structure.
  • Another disadvantage consists in the fact that the distance of the Exit opening of the application module changes from the substrate.
  • the object of the present invention is to provide a device for dispensing Provide fluids, especially flowable adhesive, that are simple A variation in the position of the application module relative to the substrate allows consistent quality of the generated job image.
  • the invention solves the problem in a device of the type mentioned in that the application module is arranged around a substantially vertical Swivel axis rotatable and fixable in different rotational positions relative to a base body is mounted.
  • the invention solves the problem in a device of the type mentioned further in that the order module on a further order module receiving Swivel arm is mounted.
  • the order module can move in a particularly simple manner different positions are brought relative to the substrate.
  • An advantage compared to the known devices is that during the Swiveling the distance from a usually horizontally moving Substrate does not change and also the angle of incidence of the fluid dispensed on the Substrate is essentially a right angle, so in any Panning position a constant order picture, such as an even one shaped caterpillar is produced.
  • the application module is either about a vertical axis pivotally attached to a stationary mountable body or alternatively on another swivel arm, which is another order module receives; in the latter case, one of the several swivel arms would be attached to one be fixed frame or the like.
  • the application module can simply swiveling the swivel arm or the order module simple variation of the position of the application module relative to the substrate is achieved are, in particular also transverse to the direction of relative movement.

  • the swivel arm is rotatably mounted on the base body.
  • a further preferred embodiment of the invention is characterized by this from that the swivel arm and the swivel axis in addition in one Essentially horizontal plane is movably mounted.
  • This is a major advantage because the position of the order module in a more complex application device with conveyor system for moving the Substrate only has to be entered once in a control device and not be re-entered when the order module is swiveled.
  • the swivel arm by means of a on the base body trained backdrop along a movement path defined by the backdrop is movable.
  • a particularly simple design results from the fact that the Backdrop is formed as a curved groove and on which Swivel arm is attached to a projection arranged in the groove, so that a Leadership exists.
  • the base body preferably has a fastening means for attachment the device on a fixed frame and is due to the backdrop predetermined path of movement of the leg selected such that in the case of methods of the leg along the substantially horizontal plane the distance of the Order module from a predetermined level by the fastener in the Remains essentially constant.
  • the pivotable mounting is formed in a simple manner in that a bearing projection is formed on the swivel arm, which with a Basic body attached bearing approach cooperates. This results in a simple, hinge-like storage. It is further preferred that the Bearing projection of the swivel arm and the bearing section of the base body as Tube sleeves are formed and the bearing section of the base body in one the base body formed groove is guided linearly.

  • the application module expediently has a pneumatically actuable one Application valve to interrupt or release the fluid flow in the Fluid channel and is at least one compressed gas channel for actuating the Order valve formed in the swivel arm. Through the compressed gas channel outer hoses can be avoided. Of course, one could electrically or electromagnetically operated application valve can be used.
  • the base body has a fluid supply channel has and several swivel arms each with one attached to this Application module are mounted on the base body and each have a fluid channel have, in the region of the pivot axis with the fluid supply channel communicated.
  • This measure can also be used to avoid external hoses become. In this case, only a single supply hose is necessary, while all further order modules through internal ones arranged in the base body Fluid supply channels are supplied. This results in the further advantages that only a temperature control device for setting a predeterminable Temperature of the fluid, especially hot melt adhesive is necessary. Further There is little heat loss when processing hot melt adhesive. It is also contemplated that electrically heated cartridges within the Swivel arms are placed to keep the hot melt adhesive at a temperature hold, which ensures the flowability of the adhesive.
