Abstract
Abstract Material handling apparatus for transferring work pieces between different stations in the form of a compact assembly having one unit capable of movement in a plane parallel to its longitudinal axis and additional units for transferring the work pieces from one location to another and also being capable of both vertical and rotary movement whereby the articles can be moved at least in a horizontal plane. The apparatus is provided with adjustable, exchangeable holders for the additional units.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
120 words
A material handling apparatus for the transfer of work pieces from one predetermined position to another predetermined position comprising at least one unit for movement along its longitudinal axis and an additional assembly having a unit for vertical movement and a unit for rotary movement, the latter being adapted to transfer said work pieces in a substantially horizontal plane, said additional assembly being provided with at least one exchangeable and adjustable holder for setting the corresponding longitudinally moving unit in the selected position relative to said additional assembly, said holder having an adjustment device provided with means to lock said longitudinally moving unit at an adjustable distance from the additional assembly and at an adjustable angle to said horizontal plane.
Claim 2
Dependent Claim
120 words
A material handling apparatus for the transfer of work pieces from one predetermined position to another predetermined position comprising at least one unit for movement along its longitudinal axis and an additional assembly having a unit for vertical movement and a unit for rotary movement, the latter being adapted to transfer said work pieces in a substantially horizontal plane, said additional assembly being provided with at least one exchangeable and adjustable holder for setting the corresponding longitudinally moving unit in the selected position relative to said additional assembly, said holder having an adjustment device provided with means to lock said longitudinally moving unit at an adjustable distance from the additional assembly and at an adjustable angle to said horizontal plane.
Claim 3
Dependent Claim
35 words
A material handling apparatus as claimed in claim 1 wherein said unit for vertical movement and said unit for rotary movement form a common structure to which exchangeable holders may be clamped in selected positions.
Claim 4
Dependent Claim
66 words
A material handling apparatus as claimed in claim 1 wherein each unit for movement along its longitudinal axis comprises an arm, and a drive cylinder operatively connected to said arm for moving the latter in a longitudinal direction, and each adjustable holder being provided with a clamping part to lock said drive cylinder, said clamping part being positioned at a selected location along said drive cylinder.
Claim 5
Dependent Claim
40 words
A material handling apparatus as claimed in claim 3 Wherein said arm is tubular and is provided with internal conduits operatively connected to said drive cylinder whereby an operating medium is supplied to said drive cylinder through said internal conduits.
Claim 6
Dependent Claim
16 words
A material handling apparatus as claimed in claim 3 wherein said operating medium is compressed air.
Claim 7
Dependent Claim
20 words
A material handling apparatus as claimed in claim 3 wherein each clamping part is movably connected to said adjustable holder.
Claim 8
Dependent Claim
52 words
A material handling apparatus as claimed in claim 3 further comprising a reciprocable piston in said drive cylinder and wherein said arm is mounted eccentrically in the ends of said drive cylinder and is eccentrically connected to said piston, said arm being non-rotatable relative to said drive cylinder and said clamping part.
Claim 9
Dependent Claim
48 words
A material handling apparatus as claimed in claim 7 further comprising conical guide pins mounted on an end of said arm, and correspondingly shaped holes in an end of said cylinder, said pins and holes mating in a predetermined position of said arm relative to said drive cylinder.
Claim 10
Dependent Claim
30 words
A material handling apparatus as claimed in claim 3 further comprising adjustable stops mounted on said arms to determine the extent of movement of said arm along its longitudinal axis.
Claim 11
Dependent Claim
37 words
A material handling apparatus as claimed in claim 9, wherein each of said stops includes a damping device provided with a damping material, and adjustment means whereby reproducible adjustment of the degree of damping may be achieved.
Claim 12
Dependent Claim
41 words
A material handling apparatus as claimed in claim 3 further comprising a magnetic gripper device operatively connected to said arm and wherein said operating medium is an electric conductor connected to said magnetic gripper device whereby electric current is applied thereto.
Claim 13
Dependent Claim
104 words
A material handling apparatus for the transfer of work pieces from one predetermined position to another predetermined position comprising at least one unit for movement along its longitudinal axis and an additional assembly having a unit for vertical movement and a unit for rotary movement, the latter being adapted to transfer said work pieces in a substantially horizontal plane, said additional assembly being provided with a plurality of exchangeable and adjustable holders removably secured on superposed levels on said vertical movement unit, each of said holders being adapted for setting the corresponding longitudinally moving unit in a selected position relative to said additional assembly.
Claim 14
Dependent Claim
104 words
A material handling apparatus for the transfer of work pieces from one predetermined position to another predetermined position comprising at least one unit for movement along its longitudinal axis and an additional assembly having a unit for vertical movement and a unit for rotary movement, the latter being adapted to transfer said work pieces in a substantially horizontal plane, said additional assembly being provided with a plurality of exchangeable and adjustable holders removably secured on superposed levels on said vertical movement unit, each of said holders being adapted for setting the corresponding longitudinally moving unit in a selected position relative to said additional assembly.
