Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
173 words
A machine for transferring objects from one work station to another, comprising an object carrier guided for vertical and horizontal movements, a first reversible drive means for raising and lowering the object carrier, a second reversible drive means for moving the object carrier horizontally to and fro, and mechanism for controlling the operation of the two reversible drive means, the control mechanism including a motor, a plurality of gears driven by said motor, said gears being in mesh with one another to form a gear train, and a bank of control cams, each of said control cams being fast with a respective one of said gears to be driven through a control cycle, each of the cams being operably connected to a selected one of said first and second drive means to cause said selected drive means to operate for a predetermined period, and the cam arrangement being such that the two drive means cause the object carrier to move through a set sequence of vertical and horizontal movements during each control cycle.
Claim 2
Dependent Claim
173 words
A machine for transferring objects from one work station to another, comprising an object carrier guided for vertical and horizontal movements, a first reversible drive means for raising and lowering the object carrier, a second reversible drive means for moving the object carrier horizontally to and fro, and mechanism for controlling the operation of the two reversible drive means, the control mechanism including a motor, a plurality of gears driven by said motor, said gears being in mesh with one another to form a gear train, and a bank of control cams, each of said control cams being fast with a respective one of said gears to be driven through a control cycle, each of the cams being operably connected to a selected one of said first and second drive means to cause said selected drive means to operate for a predetermined period, and the cam arrangement being such that the two drive means cause the object carrier to move through a set sequence of vertical and horizontal movements during each control cycle.
Claim 3
Dependent Claim
28 words
A machine as claimed in claim 1 including independent pre-settable speed controls for each of the two reversible drive means and for the control motor driving the cams.
Claim 4
Dependent Claim
22 words
A machine as claimed in claim 1 in which each of said first and second reversible drive means comprises an electric motor.
Claim 5
Dependent Claim
16 words
A machine as claimed in claim 3, in which each of said electric motors is reversible.
Claim 6
Dependent Claim
51 words
A machine as claimed in claim 1 comprising a carriage, means guiding the carriage for up and down movement in a vertical direction, and a horizontally-disposed arm mounted on the carriage for movement to and fro in the direction of its length, the object carrier being secured to the said arm.
