| 摘要 |
The invention refers to an automatic machine for accurate dispensing of liquids into pharmaceutical flasks, with two posts for simultaneous filling. The machine is designed for average production flows in pharmaceutical production facilities. The machine is made up of a frame (A) that supports a reel subassembly (B) on which some carriers (C) with flasks (5) move intermittently, which are positioned under filler heads (18) that go up and down on the vertical axis. The filler heads (18) are connected, by means of a distributor device (G), to a pumping unit (E) which is suspended by a rocker arm (46) onto a support column (43) of the frame (A). The pumping unit (E) consists of two tandem pumps (45) whose pistons are engaged simultaneously, via a cross-member (54) and an activating rod (59), by an adjustable link (63) located on a rotating disc (65). Each pump (45) has elements that ensure individual adjustment of the piston stroke, in order to equalise the doses supplied by the two pumps (45). The machine is driven by a single electric motor (33). All of the components which come into contact with the liquid can be easily mounted and removed for cleaning, washing and sterilising.
