Abstract:
1. A module for transferring a component, namely a blow head, a baffle, or a funnel of an I. S. glass molding machine, between a first position and a second position along a transfer curve composed of two partial movements, the two partial movements including a first partial movement consisting of a pivot movement around a horizontally extending axis and a second partial movement consisting of a vertically oriented linear movement, comprising: a boom on which said component is supported, said boom being mounted so as to be rotatable around the axis and is pivotable between an essentially vertically extending first position and a horizontally extending second position, a threaded spindle capable of being driven rotatably, said rotational movement being convertible successively into the two partial movements, a spindle nut which is engaged with said threaded spindle to be moveable in an axial direction in response to rotation of said spindle; a framework having two vertically extending guides which are parallel to one another, at least two carriages, including an upper carriage and a lower carriage, received in said guides, the upper carriage being configured to move in the axial direction of the spindle nut in response to movement of the spindle nut and the upper carriage has a cross head mounted thereto for movement therewith, said lower carriage having a shaft mounted thereon extending in the direction of the axis a crank drive connected to said threaded spindle via said spindle nut for initiating the first and second partial movements successively, said crank drive having at least one crank arm, at least one connecting arm linked to said crank arm, and a crank pin formed by said shaft of said lower carriage which rotates in response to movement of said crank arm, said connecting rod being connected to said cross head to convert the linear movement of the cross head along the spindle shaft into movement of the crank arm which in turn pivots said crank pin, said boom being configured to rotate with the pivoting of said crank pin, a stop disposed on one of the carriages to limit the displacement movement of the upper carriage relative to the lower carriage, with the proviso that the boom extends horizontally in the second position, and wherein said rotational movement of the threaded spindle is convertible successively into the two partial movements of the transfer curve, the pivot movement of the first partial movement is a rotational movement around the axis by the pivoting of said crank pin, which rotation is limited to an angular value, and the linear movement of the second partial movement is a movement perpendicular to the axis by linear movement of the carriages which succeeds the rotational movement.
