Abstract
Abstract The invention refers to a manipulating device, particularly for industrialobots, comprising an articulated gripping arm located and extending from a support, of the kind in which the articulated gripping arm comprises a lever system with at least a first, a second and a third member pivotally connected with the pivot axes parallel to each other, the first member being pivotally connected at the support. Such manipulating devices are equipped with at least two drive units to move a driven member to a predetermined angular relationship with respect to a preceding member or to the support as the case may be. A gripper or tool is located at the free end of the last (outermost) member. The invention particularly concerns manipulating devices for the purposes of the watch industry where relatively small parts must be precisely manipulated.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
197 words
A manipulating device, particularly for industrial robots, comprising an articulated gripping arm located on and extending from a support, said articulated gripping arm comprising a lever system having at least first, second and third members pivotally connected and mounted with the pivot axes parallel to each other, said first member being pivotally connected to the support, said manipulating device further comprising at least one first and one second drive unit to move said members to predetermined angular relationships with respect to the support, and at least one gripper or tool mounted on the third member, and having the improvement which consists in that the first member (11) forms part of a first lever parallelogram (31); in that the second (13) and third (15) members form part of a second lever parallelogram (33) having a member (35) in common with the first lever parallelogram (31), and in that two members (11,37) of said first lever parallelogram (31) have the same pivot axis (51) on the support (17) and in that said two members (11,37) are in operative connection, respectively with said first and second drive units (63,65), each of which drive units is mounted on said support (17).
Claim 2
Dependent Claim
197 words
A manipulating device, particularly for industrial robots, comprising an articulated gripping arm located on and extending from a support, said articulated gripping arm comprising a lever system having at least first, second and third members pivotally connected and mounted with the pivot axes parallel to each other, said first member being pivotally connected to the support, said manipulating device further comprising at least one first and one second drive unit to move said members to predetermined angular relationships with respect to the support, and at least one gripper or tool mounted on the third member, and having the improvement which consists in that the first member (11) forms part of a first lever parallelogram (31); in that the second (13) and third (15) members form part of a second lever parallelogram (33) having a member (35) in common with the first lever parallelogram (31), and in that two members (11,37) of said first lever parallelogram (31) have the same pivot axis (51) on the support (17) and in that said two members (11,37) are in operative connection, respectively with said first and second drive units (63,65), each of which drive units is mounted on said support (17).
Claim 3
Dependent Claim
68 words
A manipulating device according to claim 1, wherein an elevation lever system (43) is provided which is pivoted to the second lever parallelogram (33) to set the elevation of said gripper (21) and which comprises two pivotally connected levers (45, 47) of which one (45) is rigidly connected to the support (17) and the other (47) pivotally connected to a member (13) of the second lever parallelogram (33).
Claim 4
Dependent Claim
116 words
A manipulating device according to claim 1, wherein an elevation lever system (43) is provided which is pivoted to the second lever parallelogram (33) to set the elevation of said gripper (21) and which comprises two pivotally connected levers (45, 47) of which one is pivotally connected to the support (17) and the other one to a member of said second lever parallelogram (33), and a third drive unit (67) is provided to move the lever (45) which is pivotally connected to the support (17) into a predetermined angle to the support (17) so as to determine the elevation of the gripper (21) by means of said other lever (47) and said second lever parallelogram (33).
Claim 5
Dependent Claim
20 words
A manipulating device according to claim 3, wherein said other lever (47) is pivotally connected to said second member (13).
Claim 6
Dependent Claim
26 words
