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 cooperation with a first container and a second receiving area for cooperation with a second container, according to the preamble of the patent Claim 1 defined in more detail.
- the present invention also relates to a cartridge with such a head part.
- Cartridges are known from practice which are made to interact with dispensing devices. Such cartridges have, for example, two chambers in which in particular special 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 drill holes 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 provided for cooperation with an extrusion device, is proposed, the head part having a first receiving area for cooperating 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 can be ensured in an area supplied to a mixer 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 to control 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 with one another particularly precisely, see above that, for example, a desired hardening is reliably achieved.
- the control device is designed to prevent the mass from flowing back into the first container or the second container. This is a simple way of preventing the mass stored in one container from being transferred into the other container. det, whereby this transfer can come about in conventional designs that one mass in the installed state of the head part 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 other component being further present.
- control device can be designed, for example, as a flap which can be displaced in particular between a first state that completely closes off the flow cross-section of the duct and a second state that partially, in particular almost completely, releases the flow cross-section of the duct.
- 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 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.
- control device can be designed as a non-return device, in particular as a non-return valve. This makes it possible to ensure in a simple manner that a mass from a container is only passed 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 allows a control device to be arranged in the respective channel in a simple manner.
- the channels can have a different have borrowed 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 showing the control device downstream of the control device in particular exclusively with the receiving area assigned to this channel Operational connection is 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 a first container and a second container vorla conditions, the first container having a first chamber for receiving a first mass and the second container a second chamber for receiving a second Has 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 located in the cartridge can be fastened exactly in the area of the outlet openings of the channels on the head part, so that exact positioning and Dosing of the mass during application is made possible.
- Fig. 1 is a three-dimensional representation of a cartridge designed to interact with a squeezing device, which has two containers each connected to a head part;
- FIG. 2 shows a sectional view of a detail of the head part according to FIG. 1 on its own, with a control device designed as a check valve being arranged in a channel of the head part in a greatly simplified manner;
- FIG. 3 shows a three-dimensional view of the head part according to FIGS. 1 and 2, wherein a check valve that can be arranged in a channel of the head part can be seen.
- Fig. 1 shows a cartridge 1 with a head part 2, to which the present two containers 3, 4 are connected.
- 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 a container 3 of the cartridge 1 and a hardener component can be arranged in the other container 4, which is separated from it by reacting onsinhibierend.
- the resulting mass 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 buildings made of brick, concrete or natural stone.
- the boreholes required for fastening the anchoring means are made in the mineral underground, 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 strengthened 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 each having an essentially cylindrical base body 6 and 7 with a first end wall 8 and 9 and an opposite second end wall 10 and 11 respectively.
- 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 together with both containers on 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 nozzle 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 of a material to which the masses stored in the containers do not adhere.
- the head part 2 can have a non-stick coating, particularly 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 coming out of the containers 3, 4 through the channels 15, 16 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 Benzol ter 3 and conveyed via the first channel 15 through the outlet opening 18 from being passed 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 shown in Fig. 2 schematically and in Fig. 3 in a non-mounted to stood in simplified form.
- 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 foil containers, since it ensures that the container rests against a wall of an extrusion device to the desired extent and that the foil container can be folded well during an extrusion process.
- the check valve 22 can furthermore reliably prevent an undesired and / or uncontrolled flow of the mass from the container 4 and an inflow of the mass of the first Benzol age into the second container 4 and thus the occurrence of a reaction of the masses in the second container 4 .
- a spring-loaded flap can also be provided, for example, 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 into Direction of the second Benzol age 4 prevents.
- a control device is also arranged in the first channel 15 in order, for example, to reliably prevent a back flow of mass into the first container 3.
