Definitions

  • the present invention relates to a compensation device for a multi-component discharge device, which can be a two- or multi-component cartridge or syringe or a multi-component discharge device.
  • a closure cap which has a pair of plugs for closing and, rotated through 90 °, a pair of open passages.
  • the cap with the closed stopper is placed in the outlets of the cartridge and then filled.
  • the cap is removed, turned 90 ° and then put back on. Then material is discharged until it flows from both outlets into a trough in the cap, whereby the leveling can be recognized and the mixer can be fitted.
  • Fig. 1 shows a two-component cartridge, on which a compensation device according to the invention is plugged
  • a known two-component cartridge 1 and the inventive compensation device 2 is shown.
  • the cartridge 1 has two cylindrical storage containers 3 and 4 which have been filled with different materials 5 and 6, the pistons 7 and 8, shown here only schematically, which are not on the same level, closing off the storage cylinders.
  • the pistons are moved by plungers 22, 22A of a discharge device, each of which has a plunger disk 23, 23A attached to a shaft 24, 24A.
  • the two pusher disks are always at the same height, i.e. in FIGS. 1 and 2, the tappet disk 23A is located at the piston 8 and the tappet disk 23 at the same height, but at a distance from the piston 7.
  • the cartridge has a known outlet with two separate outlets 11 and 12.
  • the compensation device 2 consists of a housing 13, in which two chambers 14 and 15 are arranged, each of which can be connected to the outlets 11 and 12 of the cartridge via an inlet 16 and 17, each with a bore 18 and 19.
  • part of the housing wall protrudes beyond the pins for support on the cartridge.
  • the outlet 21 of the housing is closed off at the end opposite the inlet with a fine-pored filter 20.
  • the fine-pored filter can e.g. B. consist of a material such that it swells when wetted and thus acts as a closure, so that essentially no material can escape to the outside, especially with thin media. This also means that the overflowing material can be safely stored in the compensation device and then disposed of.
  • the compensation device It is not necessary for the compensation device to have a chamber and corresponding outlets per inlet. It is important to have separate inlets, the length of which must be such that the components cannot mix to prevent hardening at the cartridge outlet. However, if the components are optically indistinguishable or difficult to distinguish, one chamber per component is advantageous in order to be able to determine that both components have entered the respective chamber in order to ensure complete ventilation in both cartridge cylinders.
  • a cover with one or more capillary openings can be used, from which essentially only air but no material can escape.
  • the number and arrangement of the outlets can be different. So z. B. there is one outlet per chamber or the chamber outlets can open into a common outlet in the housing.
  • a fine-pored filter or one or more capillary openings can also be arranged in the individual housing outlets.
  • the air bubbles 9 and 10 which may be present in the cartridge can escape in the direction of the outlets and compensation device.
  • the two pistons have been pushed in so far by the plunger 22, until any air still escaped and the two components get into the compensating device or into the chambers 14 and 15 and the pistons are balanced. This means that the two pistons are at the same level, so that when they are subsequently discharged, both components enter the mixer at the same time, which ensures that the exact mixing ratio is maintained.
  • the entry of the material into the chambers is visualized, for example by the fact that the entire compensation device or only the chambers or parts thereof are made of a transparent material.
  • FIG. 4 shows the compensating device drawn off from the completely vented cartridge with the pistons located at the same level.
  • a mixer or an accessory such as a transfer or extension part is connected to the cartridge, or the sealing plug can be replaced on the cartridge.
  • FIGS. 5, 5A, 6, 6A show an embodiment variant of a compensating device which has a closure of the inlets.
  • the equalizing device 25 has the same housing, the same chambers, outlets and filters as in the device according to FIGS. 1-4.
  • the inlet part 26 with the two inlets 27 and 28, each with a bore 29 and 30, is rotatably arranged in the lower section of the housing 13 and the housing base 13B, which separates the chambers from the inlet part, has two passages 31 and 32 , see Figure 6.
  • the housing 13 has two bayonet tabs 33, 33A, which cooperate with corresponding bayonet sockets on the cartridge.
  • the inlets 27, 28 are arranged in relation to the bayonet brackets in such a way that their bores 29, 30 communicate with the passages 31, 32 in the housing base when the balancing device is plugged on and then locked by turning. After the cartridge has been leveled and vented, the leveling device is unlocked by turning, which closes the passages so that no material can escape from the leveling device.
  • the compensation device is not limited to a two-component cartridge and can be used for any type of discharge device in which complete venting and piston compensation are sought at the same level.
  • the compensation device can also be attached to a transfer part between the cartridge or discharge device and mixer, so that this part is also vented and completely filled.
  • a closure with a rotatable inlet part according to FIGS. 5 and 6 can also be used for temporarily closing another accessory part, for example for closing a transfer part, if it is desired to prevent material from flowing out, the accessory part being separated from one another between the inlet part Inlet and the remaining part of the accessory has a floor with passages that either communicate with the holes of the inlets or are closed after turning the accessory.
  • the housing can have bayonet closure parts which, in a coded arrangement known per se, have such a connection with the other bayonet closure part
  • connection between the compensation device and the cartridge can also be established by means of various types of snap closures known per se, in which a bead or the like on one part engages behind a collar or bead on the other part.

Abstract

L'invention concerne un équilibreur pour cartouche à deux composants (1), qui présente des moyens (16, 17) de jonction amovible avec la cartouche, un nombre d'entrées (16, 17) séparées les unes des autres, correspondant au nombre de composants (5, 6) et au moins une chambre (14, 15) comportant au moins une sortie (21). Ladite sortie (21) est obturée de sorte à être sensiblement étanche aux composants, mais à être perméable à l'air. Un tel équilibreur amovible permet de ventiler pleinement des réservoirs de dispositifs d'éjection de composants multiples et les pistons (7, 8) du dispositif d'éjection sont équilibrés au même niveau, afin que tous les composants parviennent simultanément dans le mélangeur, au début de l'éjection.
