Definitions

  • the present invention relates to a head part for a cartridge which is provided for cooperation with an extrusion device, the head part having a first receiving area for interaction with a first container and a second receiving area for cooperation with a second container, according to the preamble of claim 1
  • the type defined in more detail The present invention also relates to a cartridge with such a head part.
  • Cartridges are known from practice which are designed to interact with dispensing devices. Such cartridges have, for example, two chambers in which, in particular, different materials are stored.
  • a two-component mortar mass can be located in the chambers, a hardenable resin component being arranged in one chamber and a hardening component being arranged in a further chamber, which is arranged separately in a reaction-inhibiting manner.
  • Cartridges with such two-component mortar masses are used, for example, as injection mortars for the chemical anchoring of, for example, metal elements in mineral substrates, such as in particular buildings made of brickwork, concrete or natural stone.
  • the boreholes required for fastening the anchoring means are drilled into the mineral substrate, after which the hardenable resin component is mixed with the hardener component of the two-component mortar mass and introduced into the borehole, whereupon the anchoring means to be fastened is introduced and adjusted, after which the Mortar mass hardens.
  • Known cartridges have a head part on which the two chambers are each arranged in a receiving area.
  • the head part has two channels, one channel being connected to the first chamber and a second channel being connected to the second chamber.
  • the channels are separated from one another in the area of the head part.
  • the head part has a connection area to a mixer which can be connected to the head part.
  • the mixer has a structure for mixing the masses and an outlet opening for dispensing the mixed mass.
  • a head part for a cartridge which is intended to interact with an extrusion device, the head part having a first receiving area for interacting with a first container and a second receiving area for interacting with a second container, the first receiving area having a first Channel and the second receiving area are connected to a second channel that is at least partially separated from the first channel.
  • a control device for controlling a volume flow of a mass guided through the corresponding channel is arranged in at least one channel.
  • an entire volume flow or mass flow supplied to the corresponding channel via the receiving area can be controlled in a structurally simple manner.
  • a desired mixing ratio of the masses located in the two containers or chambers in an area fed to a mixer can be ensured in a simple manner in all operating states and thus the occurrence of mixing faults and / or incomplete curing can be reliably prevented.
  • a control device is provided in both channels for controlling the amount of a mass passed through the corresponding channel, in particular a mass flow or a volume flow, the mass flows or volume flows of the individual masses passed through the channels can be coordinated particularly precisely with one another, so that for example, a desired curing is reliably achieved.
  • the control device is designed to prevent the mass from flowing back into the first container or the second container. In this way, it can be prevented in a simple manner that the mass stored in one container does not pass into the other container, In conventional designs, this transfer can come about in that, when the head part is installed, one mass passes through the mixer into the channel assigned to the other container.
  • the solution according to the invention is particularly advantageous when using chemical systems in which a chemical reaction of the components or masses used continues after an initiation even without the further presence of the other component.
  • control device can for example be designed as a flap which can be displaced in particular between a first state that completely closes off the flow cross section of the channel and a second state that partially, in particular almost completely, exposes the flow cross section of the channel.
  • a spring device is provided which applies a force to the flap in the direction of the first state.
  • the control device has a spring device.
  • the spring device is designed in such a way that it releases a volume flow through the corresponding channel when a defined force acts against the spring force of the spring device.
  • the spring device is designed in particular in such a way that it only releases a volume flow through the channel when a defined minimum pressure is applied to the control device upstream of the control device and releases the channel against the defined spring force of the spring device. In this way, an undesired and / or uncontrolled after-flow of a mass or component from the respective container can be prevented in a simple manner.
  • more favorable folding of the foil can be achieved as a result, since the minimum pressure that can be set via the control device can ensure that the foil rests securely on a wall of the dispensing device.
  • control device can be designed as a non-return device, in particular as a non-return valve. In this way, it can be ensured in a simple manner that a mass from a container is only guided through the corresponding channel via the corresponding receiving area when it exceeds a defined minimum pressure.
  • the first channel and / or the second channel preferably have a substantially circular cross section. This enables a control device to be arranged in the respective channel in a simple manner.
  • the channels can be different from each other Have diameter.
  • the channels can be arranged coaxially to one another at least in some areas.
  • the channel having the control device is separated from the other channel and the corresponding receiving area downstream of the control device, so that the channel having the control device is in operative connection downstream of the control device in particular exclusively with the receiving area assigned to this channel and is separated from the other channel and the receiving area assigned to this channel.
  • the first channel and the second channel are preferably separated from one another in the entire head part, the first channel only being connected to the first receiving area and the second channel only being connected to the second receiving area. Contact of the masses located in the two containers is therefore excluded in the area of the head part.
  • a cartridge for an extrusion device with a head part described in more detail above and at least one first container and a second container is also proposed, the first container having a first chamber for receiving a first mass and the second container having a second chamber for receiving a second mass .
  • Both the head part and a mixer which can be brought into operative connection in a conventional manner with the head part are preferably formed from a material to which the compounds intended for use do not adhere.
  • the head part and / or the mixer can be designed with a coating that fulfills this purpose.
  • the head part can have a thread, via which commercially available attachments or extrusion devices for applying the mass in the cartridge can be attached to the head part exactly in the area of the outlet openings of the channels, so that exact positioning and dosing the mass is enabled during application.
  • Fig. 1 shows a cartridge 1 with a head part 2, to which two containers 3, 4 are connected in the present case.
  • the cartridge 1 is designed to interact with an extrusion device, by means of which masses located in the containers 3, 4 can be manually or automatically squeezed out to the desired extent.
  • the cartridge 1 contains, for example, a two-component mortar mass, wherein a hardenable resin component can be arranged in one container 3 of the cartridge 1 and a hardener component can be arranged in the other container 4, which is arranged separately in a reaction-inhibiting manner.
  • the mass produced after mixing the curable resin component and the hardener component is used, for example, as an injection mortar for chemical anchoring, for example, of metal elements in mineral substrates, such as in particular buildings made of brick, concrete or natural stone.
  • the boreholes required for fastening the anchoring means are drilled into the mineral substrate, after which the hardenable resin component is mixed with the hardener component of the two-component mortar mass and introduced into the borehole, whereupon the anchoring means to be fastened is introduced and adjusted and the mortar mass then hardens.
  • the masses are each arranged in chambers of the containers 3, 4, the containers 3, 4 in the present case each having an essentially cylindrical base body 6 or 7 with a first end wall 8 or 9 and an opposite second end wall 10 or 11.
  • the first end wall 8 or 9 has a dispensing opening or an area provided for releasing the mass located in the respective container 3 or 4.
  • the containers 3, 4 are embodied as containers 3, 4 which are at least partially, in particular almost completely, made with foils, and in an alternative embodiment can also be embodied as so-called hard cartridges or the like.
  • the head part 2 has a first receiving area 13 and a second receiving area 14 spaced apart from one another, the first receiving area 13 being provided for connecting the first container 3 to the head part 2 and the second receiving area 14 being intended for connecting the second container 4 to the head part 2 .
  • the receiving areas 13 and 14 are arranged without a direct connection to one another.
  • one container of the cartridge is arranged inside the other container of the cartridge.
  • the cartridge is here can be fastened jointly with both containers to the head part, the head part in turn having a first receiving area assigned to the first container and a second receiving area assigned to the second container.
  • One receiving area is encompassed by the other receiving area, the receiving areas being separated from one another in such a way that the respective receiving area is exclusively in contact with the assigned container and thus the material stored in the respective container.
  • a channel 15 or 16 is assigned to both the first receiving area 13 and the second receiving area 14, the first channel 15 being connected to the first receiving area 13 and not being in contact with the second receiving area 14.
  • the second channel 16 is connected to the second receiving area 14 and accordingly has no contact with the first receiving area 13. This ensures in the present embodiment that the masses located in the containers 3, 4 cannot come into contact with one another before they exit an outlet opening 18 of the head part 2.
  • the head part 2 has an essentially tubular outlet connection 17 with an essentially circular cross section.
  • the channels 15, 16 are arranged in the outlet connector 17, the channels 15, 16 running separately from one another within the outlet connector 17.
  • the second channel 16 has a circular cross section and the first channel 15 has an essentially sickle-shaped cross section, the first channel 15 being separated from the second channel 16 by a wall 19.
  • the shape of the cross-sections of the channels 15, 16 can, however, in principle be selected as desired.
  • the outlet connection 17 thus has the two channels 15 and 16 which are in fluid connection with the respective receiving area 13 and 14 and are separated from one another by the wall 19.
  • the wall 19 extends from a connecting web 21 separating the receiving areas 13 and 14 to the outlet opening 18 of the head part 2.
  • the head part 2 is made in particular from a material to which the masses stored in the containers do not adhere.
  • the head part 2 can have a non-stick coating, in particular in the areas that interact with the masses, such as the channels 15, 16.
  • connection area 19 for a conventionally designed static mixer is arranged on an outer circumference of the outlet connection 17 or outlet pipe.
  • the connection area 19 is designed as a thread, so that a mixer can be arranged on the head part 2 in a screwing movement.
  • Such a mixer has a Structure which leads to the most favorable possible mixing of the masses guided through the channels 15, 16. Via the structure of the mixer, the masses, which are guided via the channels 15, 16 and come from the containers 3, 4, come into contact with one another for the first time in the direction of flow.
  • a control device 22 designed here as a check valve is arranged in the second channel 16.
  • the check valve 22 reliably prevents the mass located in the container 3 and conveyed via the first channel 15 through the outlet opening 18 from being guided upstream through the check valve 22. The mass located in the container 3 is thus reliably prevented from reaching the second container 4.
  • the check valve 22 is in Fig. 2 schematically and in Fig. 3 shown simplified in a non-assembled state.
  • the check valve 22 has a spring device 23 which closes the second channel 16 without an external force being applied.
  • the check valve 22 only releases a volume flow through the second channel 16 when an external force applied to the check valve 22 on the container side exceeds the spring force of the spring device 23.
  • the mass stored in the container 4 can thus only be guided through the second channel 16 in the direction of the outlet opening 18 of the head part 2 when a defined minimum pressure present in the second container 4 is exceeded. This is particularly advantageous when using film containers, since it ensures that the container rests against a wall of an extrusion device to the desired extent and that this results in a desired good folding of the film container during an extrusion process.
  • the non-return valve 22 can also reliably prevent an undesired and / or uncontrolled flow of the mass from the container 4 and an inflow of the mass of the first container 3 into the second container 4 and thus the occurrence of a reaction of the masses in the second container 4.
  • a spring-loaded flap for example, can also be provided, which allows the mass to flow out of the second container 4 in the direction of the outlet opening 18 and a mass to flow in the direction of the second container 4 and thus a backflow in the direction of the second container 4 prevents.
  • control device is also arranged in the first channel 15 in order, for example, to also reliably prevent a backflow of mass into the first container 3.
