Definitions

  • the invention relates to a dispensing device for operating double cartridges, which have two storage cylinders arranged parallel to one another and a mouth part connecting them, the dispensing device having two plungers, each associated with one of the cartridge cylinders, guided longitudinally movably with a predetermined center distance, and one provided with a guide for the cartridge mouth part Holding device for exchangeable receiving the cartridges.
  • the double cartridges intended for operation by the discharge device are used in a known manner for processing so-called two-component masses. They contain the two related masses or components separately from one another in their storage cylinders, the cylinders being closed at their ends opposite the mouth part by a delivery piston.
  • a double cartridge is inserted into the holding device of the device for processing.
  • the two plungers of the device and the delivery pistons acted upon by them are then driven in a synchronized stroke movement, whereby the content is discharged volumetrically from each cylinder according to the cylinder cross-section.
  • Such a discharge device is described, for example, in EP-A-0 276 665, and reference is made to EP-A-0 294 672 as an example of a double cartridge of the type mentioned.
  • the object of the present invention is to design the aforementioned discharge device in such a way that cartridges of different types, namely with two different diameter ratios of their cylinders, can be used without changes to the holding device and are correctly aligned.
  • the discharge device is characterized by latching means, which are arranged in the area of the holding device and are intended for aligning the cartridge cylinders with the plungers, which have separate latching elements which are assigned to each of the plungers and are dimensioned for different cylinder diameters.
  • latching means which are arranged in the area of the holding device and are intended for aligning the cartridge cylinders with the plungers, which have separate latching elements which are assigned to each of the plungers and are dimensioned for different cylinder diameters.
  • the discharge device shown only partially has a head plate 8, in which two plungers 10 are guided to be longitudinally movable; the predetermined distance between the two tappet axes 11 is denoted by d.
  • the plunger 10 are drawn in their starting position, from which they are driven to the left for actuating double cartridges (in FIG. 1).
  • the known drive part for the plunger 10 is located on the right side of the head plate 8 and is largely broken away in FIG. 1. It is, for example, a pneumatic cylinder / piston unit, the cylinder 9 of which is attached to the head plate 8 and whose piston (not visible) drives the two plungers 10.
  • An extension 7 at the bottom of the head plate 8 is used to fasten a handle, also not shown, for the discharge device.
  • the holding device On the side of the head plate opposite to the ram drive there is a holding device for exchangeably accommodating double cartridges 20.
  • the holding device essentially consists of an end plate 13 and two parallel struts 12 connecting the end plate 13 to the head plate 8.
  • the double cartridges 20 to be operated by the discharge device and to be inserted into the holding device 12, 13 have two storage cylinders 21, 22 arranged side by side with parallel axes.
  • the two cylinders are connected at one end by an orifice part 23, while a feed piston 25 to be acted upon by the plungers 10 is inserted into the other end.
  • the two cylinders 21, 22 are preferably additionally connected in the region of the end on the ram side by means of webs or the like, as indicated in FIG. 1.
  • a vertical slot 14 in the end plate 13 forms a guide for the mouth part 23 of the double cartridge 20 located in the holding device, which is to be inserted from above in the present example.
  • the two cylinder axes lie one above the other in the same vertical plane 16 (FIG. 2), which also contains the two tappet axes 11.
  • the center distance of the cartridge cylinders 21, 22 corresponds at least approximately to that of the two plungers 10.
  • the mouth part 23 has a circumferential, flange-like rib 24 which engages in a groove 14a provided in the slot 14.
  • the double cartridge 20 according to FIGS. 1, 2 and 3a has two cylinders 21, 22 of the same diameter (cross-sectional or discharge ratio 1: 1).
  • 3b differs from FIG. 3a only in that a double cartridge 20a is used, the cylinders 21a, 22a of which have different diameters, in the present example for a cross-sectional or discharge ratio of 2: 1.
  • Both the cylinders of the cartridge 20 (FIG. 3a) and the cartridge 20a (FIG. 3b) are aligned with their axes on the axes 11 of the respectively associated plunger 10. This is ensured without any change on the discharge device or on the holding device, thanks to the special latching means described below for aligning the cartridge cylinders 21, 22 and 21a, 22a with the two plungers 10.
  • each of the plungers 10 are assigned to these latching means Locking elements 31 and 32 are provided, and the locking elements mentioned are dimensioned for different cylinder diameters: in the present example, the locking element 32 corresponds to the diameter of the cylinder 22 and the locking element 31 corresponds to the larger diameter of the cylinder 21a.
  • the latching means arranged in the region of the holding device are preferably, as in the present example, formed on a guide part 30 which is detachably connected to the holding device.
  • the guide part 30 is a shell-shaped plastic injection-molded part, which is located essentially between the two struts 12 and overlaps the latter with its edges;
  • pawl-shaped projections 36 on the guide part 30 which engage in openings 15 on the struts 12, a snap connection is made, which can be released if necessary.
  • Ribs 33 are formed on the inside of the shell-shaped guide part 30 in the front and rear end region of the cartridge cylinder, which ribs form the latching means mentioned.
  • the ribs 33 are located on both sides of the cartridge cylinder (symmetrical to the plane 16) and, as latching members, have edge sections 31 and 32 in the form of a circular arc. As can be seen, both the cartridge 20 and the cartridge 20a can be inserted between the latching members 31, 32 lying one above the other. At the "entrance" to the lower locking member 32 for the smaller diameter, the ribs 33 form locking cams 34, and for the larger cylinder 21a, the raised ends of the ribs 33 form resilient locking cams.
  • a downwardly projecting pin 35 is mounted so that it can be moved vertically. This is held by the cartridge in the lower end position shown when the cartridge is correctly inserted. This position is transferred to a mechanism, not shown, built into the handle of the discharge device, which prevents the plunger from being driven as long as a cartridge is not correctly inserted (see EP-A-0 331 942).
  • the cartridge 20 it is the lower cylinder 22 which holds the pin 35 in the lower position.
  • a rib 25 is formed on the smaller cylinder 22a at the bottom, which extends as far down as the cylinder 22.
  • the rib 25 should be present at least in the area of the pin 35, may but also extend over the entire length of the cylinder 22a.
  • the holding device of the device is to be equipped with the corresponding latching means, for which purpose the formation of the latching means on a detachably fastened guide part is particularly suitable.
  • the principle described can also be implemented in an analogous manner on dispensing devices, the holding device of which holds the double cartridges with storage cylinders lying next to one another instead of one above the other.
