The invention relates to a transfer device for performing a regular, linear transfer movement. The transfer device comprises a body (1), provided with a threaded bar (2), a stepping motor (3) for driving the threaded bar (2), two guide bars (4, 5), a slide (6), and a follower (7) connected to it. The slide (6) is moved along the guide bars (4, 5) by means of the follower (7), which transforms the rotational movement of the threaded bar (2) into a linear transfer movement. The object to be transferred with the transfer device is attachable to the slide (6). The invention is characterised by the fact that the slide (6) comprises an opening (8), through which the threaded bar (2) is fitted to pass with some play, and in connection with the opening (8) there is a follower (7), comprising a tongue (9), which is fitted to follow the threaded groove (10) of the threaded bar (2), so that the rotational movement (A, B) of the threaded bar is transformed into a linear movement of the slide (6) via the follower (7). <IMAGE> |
