Abstract
Abstract The material handling apparatus is a robot which is capable of moving articles from and to a plurality of positions. The entire apparatus is constituted of several units which perform various movements. One of the units is an arm having a gripper attached to its free end. The gripper is mounted on a device that imparts a turning movement to an article being handled. Damping structures are mounted in the device which provide the proper damping for the gripper in the end positions of the turning movement, and are easily adjustable for different loading conditions. If desired, the gripper can be interchanged for a different gripper.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
A turning movement device for a gripper of a material handling apparatus for angular movement of an article forwards and backwards through a predetermined angle comprising: a. a block element which is removably secured to the material handling apparatus, b. an attachment member for the gripper being pivotally supported on the element and movable through said predetermined angle, c. a driving motor for the attachment member, d. adjustable damping means for damping the movement of the attachment member in the two end positions of its turning movement, e. a driving medium for said driving motor and gripper, and f. said block being provided with passageways for flow of said driving medium to said gripper and driving motor, said material handling apparatus having a corresponding passageway, and at least one of the passageways in said block being automatically connected to the corresponding passageway when the block is fixed to said material handling apparatus.
Claim 2
Dependent Claim
152 words
A turning movement device for a gripper of a material handling apparatus for angular movement of an article forwards and backwards through a predetermined angle comprising: a. a block element which is removably secured to the material handling apparatus, b. an attachment member for the gripper being pivotally supported on the element and movable through said predetermined angle, c. a driving motor for the attachment member, d. adjustable damping means for damping the movement of the attachment member in the two end positions of its turning movement, e. a driving medium for said driving motor and gripper, and f. said block being provided with passageways for flow of said driving medium to said gripper and driving motor, said material handling apparatus having a corresponding passageway, and at least one of the passageways in said block being automatically connected to the corresponding passageway when the block is fixed to said material handling apparatus.
Claim 3
Dependent Claim
70 words
A turning movement device as claimed in claim 1 further comprising a fixed stop on said attachment member, a bushing in the other end of said cylinder and enclosing the piston rod of said piston, one surface of said bushing limiting the movement of said piston in one direction and another surface of said bushing acting as a fixed stop and co-acting with the fixed stop of said attachment member.
Claim 4
Dependent Claim
181 words
A Turning movement device for a gripper of a material handling apparatus for angular movement of an article in a vertical plane forwards and backwards through a predetermined angle comprising: a. a block element which is removably secured to the material handling apparatus, b. an attachment member for the gripper being rotatably supported on the element and movable through said predetermined angle, c. a pair of spaced stops mounted on said attachment member each having its major axis extending in a direction substantially parallel to the axis of rotation of said attachment member, d. a driving motor for the attachment member, and e. separate adjustable yieldable damping means for damping the movement of the attachment member in the two end positions of its turning movement when engaged by an adjacent stop, said damping means including a cylinder, compressible material of foamed plastic with open pores in said cylinder, a damper piston adapted for reciprocation in said cylinder, and an adjustment member in said cylinder for precompressing the material to a selected degree thereby changing the damping characteristics of the damping means.
Claim 5
Dependent Claim
181 words
A Turning movement device for a gripper of a material handling apparatus for angular movement of an article in a vertical plane forwards and backwards through a predetermined angle comprising: a. a block element which is removably secured to the material handling apparatus, b. an attachment member for the gripper being rotatably supported on the element and movable through said predetermined angle, c. a pair of spaced stops mounted on said attachment member each having its major axis extending in a direction substantially parallel to the axis of rotation of said attachment member, d. a driving motor for the attachment member, and e. separate adjustable yieldable damping means for damping the movement of the attachment member in the two end positions of its turning movement when engaged by an adjacent stop, said damping means including a cylinder, compressible material of foamed plastic with open pores in said cylinder, a damper piston adapted for reciprocation in said cylinder, and an adjustment member in said cylinder for precompressing the material to a selected degree thereby changing the damping characteristics of the damping means.
Claim 6
Dependent Claim
16 words
A turning movement device as claimed in claim 3 wherein the compressible material is an elastomer.
Claim 7
Dependent Claim
19 words
A turning movement device as claimed in claim 4 wherein the elastomer is a foamed plastic with open pores.
