Definitions

  • Discharge device as well as box for insertion in a discharge device
  • the invention relates first of all to a dispensing device for local foam which forms a handle with a receiving holder for an orbital foam can with two or more receiving holders for a can such as a local foam can and a can of further substance and at least one discharge tube connected to the dispensing device, the substances being able to be dispensed from at least two doses through the same discharge tube.
  • Dispensing devices of this type are also known, in which two cans with different substances can be arranged, these substances being dispensed as a mixture via the dispensing tube by means of the dispensing device.
  • the object of the invention is in any case to simplify the cleaning system in terms of handling.
  • This object is first and essentially achieved in a discharge device with the features of claim 1 in that the discharge device has a switching element for alternately releasing the one discharge tube for the at least two substances.
  • a discharge device of increased utility value is achieved: on-board equipment is available for the required cleaning.
  • the can for the integrated additional substance has its own docking point.
  • Working with such a device, here the so-called foam gun, is much easier. It is now no longer necessary to carry a separate socket with you at all times.
  • Both sources of the discharge device are flow-connected or connectable to at least one discharge tube. The two cans themselves do not require a discharge tube, as is common with cartridges available on the market. Discharge via the same discharge tube can take place via a Y-fork.
  • the one substance is the cleaning substance.
  • the latter not only serves to clean the foam path of the foam gun, but also to remove fresh splashes of assembly foam and also to clean / degrease substrates.
  • the described multi-way access can also be used in such a way that at least one substance is a supplemental substance such as expandable graphite.
  • a supplemental substance such as expandable graphite.
  • expandable material available in this regard reference is made to DE 100 60 513 AI.
  • corresponding supplements can also be a wide variety of color admixtures.
  • the invention proposes that two parallel discharge tubes are provided which are connected to at least one substance.
  • the device can also initially have holders for two cans with discharge substances, which substances are each transported through a discharge tube.
  • the Do se with the cleaning substance can be received in a third holder.
  • both discharge tubes are then preferably released for the cleaning substance to flow through.
  • two discharge tubes, assigned to their discharge end be put into one common mixing chamber open and that the mixing chamber has a discharge opening. Mixing occurs immediately before the foam bead is applied.
  • An advantageous assignment of the cans is achieved when two cans are arranged in the receiving holders directed against each other.
  • the handle at least partially surrounds at least one of the cans.
  • the handle is so useful as a can chamber.
  • at least one can is accommodated covered in the holder.
  • At least one can is preferably arranged entirely within the handle.
  • the handle of the receptacle holder receiving the nozzle has a cross-section that differs from the circular shape of the socket. This can be used in terms of grip to form a flat shape, so that such a grip lies well in the hand and can be safely aligned with the discharge device with respect to the destination.
  • the handle does not turn in the holding hand.
  • the handle is closed.
  • the handle that holds the can has a lower lid shape that adjoins the handle. It is provided that the lid shape is firmly connected to the can as a part to be exchanged with the can. The part of the lid that complements the handle can have content detections that are also visible when assigned. Such a lid shape can even serve as an originality feature.
  • An advantageous handling is achieved in that the switching element consists of a valve outside the cans, which opens the way to the discharge tube, and an actuating element for acting on the outlet valve of one of the cans.
  • the switching element has a double function, on the one hand as a valve for clearing the way to the discharge tube for one or the other can and also as an actuating element in one of the aforementioned valve positions for releasing pressure on the one arranged in one of the cans, integrated valve.
  • the valve on the switching element side and the actuating element can be combined as a structural unit.
  • the switching element consist of a valve outside the cans, which opens the way to the dispensing tube, and an actuating element for acting on the outlet valve of one of the cans or for acting on a further release valve.
  • the switch-side valve and the actuating element or the further release valve can be combined as a structural unit.
  • the switchover element can also be a switch that can be actuated independently of a discharge actuation, for example via a hand lever.
  • the actuation of the switching element consequently does not result in the direct discharge of one or the other substance in this embodiment. Rather, the actuation of a trigger-like actuation lever is necessary for the discharge.
  • the switching element is only used to prepare for the release of one or the other substance.
  • the outlet valves of the cans can remain in a permanent open position by correspondingly holding them.
  • the feed channels of the cans up to the release valves on the device side are always under pressure.
  • the discharge of the selected substance is made possible by switching over by means of the switchover element and the associated relocation of one or the other release valve into the position in which the feed line is connected by line to the discharge tube.
  • only one of the cans can be arranged on the device in such a way that its outlet valve remains in a permanent open position, while the outlet valve of the other can is arranged in the device in an unloaded state.
  • Via the switching element either the device-side release valve associated with the can provided with the permanently open outlet valve is opened or the outlet valve of the other can is acted upon directly via the actuating element.
  • the switching element can be directly connected to the outlet valve of a do- act or release corresponding discharge paths for one or the other substance by acting on a release valve in the device.
  • more than two cans of a device can also be controlled via the switching element, for example two cans for the preparation of a two-component foam, the substances of which are mixed in a corresponding chamber with simultaneous release, for example before entering the discharge tube.
  • the switching element is therefore in a position in which both cans are unlocked.
  • a third can with the cleaning substance is activated via the switching element.
  • the device can also be provided with two holders for receiving two-component cans.
  • the switchover element is aligned such that both channels facing the cans are connected in line with the discharge tube, while in the cleaning position of the switchover element only the channel of a predetermined holder for receiving the cleaning canister with the discharge tube and possibly with the upstream mixing chamber is connected in terms of flow.
  • the switch is preferably a rotary switch, it being further proposed in this regard that the rotary switch acts on the release valve via a hinged lever. This lever is further preferably articulated eccentrically to the axis of the rotary switch, the free end of the lever acting translationally on the release valve.
  • the rotary switch can act on the release valve via a cam control, for example via a cam arranged on the physical axis of the rotary switch.
  • One or the other release valve is preferably biased in its open or closed position, it being preferred in this regard that the release valve assigned to the can with the cleaning substance is biased into the open position by means of a spring, while the release valve of the other can, for example the local foam can, is biased Spring in the closed position is excited.
  • the device-side release valve clears the way for the substance into a transition chamber upstream of the discharge pipe. This transition chamber is moreover preferably flow-connectable to both cans, so if necessary with the interposition of release valves.
  • the discharge tube is penetrated by a locking needle passing through the transition chamber, via which the dispensing of one or the other substance can be controlled by means of an actuating lever, the locking needle, in cooperation with the discharge tube, constituting a dispensing valve, as is the case, for example, in the area of paint spray guns is known.
  • the quantity dispensed when the actuating lever is moved can also be preset using such a locking needle.
  • the shut-off needle can interact with the discharge-side end of the discharge tube. In this regard, an alternative is proposed in which the shut-off needle interacts with the end of the discharge tube on the holder side and consequently, facing the transition chamber, constitutes a valve miss.
  • the actuating element can optionally be actuated with the aid of a switching part by means of the actuating lever, with a separate actuating element preferably being assigned to each can, via which the integrated outlet valve of the can is acted upon.
  • a separate actuating element preferably being assigned to each can, via which the integrated outlet valve of the can is acted upon.
  • the one or the other actuating element for releasing the respective can contents is acted upon via the actuating lever.
  • the switching part acts on a transmission lever, which in turn acts on an actuating element.
  • the transmission lever itself can form the actuating element.
  • the switching part is arranged concentrically to a locking needle and is further preferably rotatable about an axis perpendicular to the actuation axis of the actuation lever.
  • lever accessible for dispensing the first or second can contents.
  • the actuating lever overlaps the switching part with a clearance in a position that does not act on the dispensing valve of the second box.
  • the handle with the actuating lever is arranged in relation to the discharge tube arranged at the front and partly in overlap with one of the cans.
  • the Do sen together with the handle form a triangular arrangement, with the two cans or the holding portions of the applicator receiving them enclose approximately a right angle to each other.
  • one of the cans, more preferably the can containing the second substance is arranged approximately flush with the discharge tube.
  • the switching element can also be arranged in the region in which the longitudinal axes of the cans converge.
  • the switching element can also be arranged in a gusset area which is enclosed by the longitudinal axes of the cans.
  • the actuating lever is arranged within the triangle spanned by the handle and the cans, and consequently lies in a protected position within the triangular arrangement.
  • the switching element is furthermore arranged with respect to both cans on the side of the discharge tube and in its axial extension, a preferred positioning of the switching element being proposed in a crossing region of the axis of the discharge tube and one of the can axes.

  • triggerable substance delivery is achieved, for example by axially displacing the closure needle within the discharge tube, a closure valve formed in the sealing seat between the closure needle and the discharge tube being opened.
  • this closure valve is formed in the holder-side end, that is to say in the area of the substance entering the discharge tube, so that the opening cross section of the discharge tube can be relatively large over almost the entire length thereof, which means that the passage of the substance, in particular if it is a Local foam or the like is easier and also offers an improved cleaning option.
  • the tube cross section is free because the needle does not penetrate it.
  • the outlet valve of the one can possibly also that of the further can, is constantly open and the discharge can be controlled via the shut-off needle.
  • the device or the channels which are connected in terms of flow in terms of flow are under permanent pressure, since their outlet valves are held in a permanent open position by the selected fixing of the boxes on the device.
  • the invention then relates to a can for insertion into a local foam discharge device, the can also containing a substance other than local foam, such as a cleaning substance and / or expandable graphite, and further suggests that the can has a lid shape for closing Fitting in a receptacle of the discharge device, and that the shape of the cover of the cylindrical box provides a roll-off protection.
