Patent number: 11260539Abstract: Object manipulation space optimization is a challenging task and used in applications such as heat treatment operation and transport packaging. Traditionally manual intervention is involved to grasp and place the objects for ensuring multi object stacking with zero gap between adjacent objects. This leads to higher cost infrastructure and low productivity. Further, conventional gripper devices fail to optimize object manipulation space and are unable to handle objects of different cross sections with larger lengths. The present disclosure provides a gripper apparatus addressing a single gripper design comprising an adaptor holding unit with a provision for different modular object holding units which are varied in accordance with size, shape and length of the object to be grasped and placed by the gripper apparatus. The modular object holding unit comprises a plurality of fingers which are actuated for grasping and stacking one or more objects such that object manipulation space is optimized.Type: GrantFiled: September 23, 2020Date of Patent: March 1, 2022Assignee: Tata Consultancy Services LimitedInventors: Venkatesh Prasad Bangalore Srinivas, Pradeep Prabhakar Kamble

Patent number: 5074734Abstract: An unrolling device for cylindrical hay bales spikes the bale on its axis and pulls it along the ground to unroll it, when the device is pulled by a pickup truck, tractor, or the like. It comprises a transverse crossbar, two arms hinged at their ends to respective ends of the crossbar, and spikes insertable through the arm ends. The arms may swing out from the bar to a right angle; when both are swung out they lie parallel to one another. The spikes fit through the arm ends to protrude inwardly in the same plane as the plane formed by the crossbar and arms. Thus when set up for use the device has the general shape of a serif capital letter C. In use, the arms are set out on either side of a bale and the spikes are inserted through the arm ends to penetrate the hay bale on its axes. The device is pulled by chains on the crossbar to unroll the bale. When not in use, the device folds into a compact linear shape; the spikes are removed and the arms are folded down.Type: GrantFiled: November 5, 1990Date of Patent: December 24, 1991Inventors: Gary F. Price, James Chapman

Patent number: 5028085Abstract: A bale handling implement is disclosed having a pair of elongated arm members rotatably attached to a mounting support such that the arms are rotatable about their longitudinal axes. The arms, which have several teeth extending from one side, rotatably pass through a support bushing that is directly attached to the mounting support. The elongated arms are rotated by a single, fluid actuated power cylinder attached to the mounting support between a position in which the teeth extend generally downwardly and a position in which the teeth engage the hay bale to facilitate its lifting. A linkage mechanism interconnects the actuating rod of the fluid actuated power cylinder to crank arms attached to the elongated arm members such that extension and retraction of the actuating rod causes the arm members to rotate about their longitudinal axes.Type: GrantFiled: April 19, 1990Date of Patent: July 2, 1991Inventor: J.

Patent number: 4604018Abstract: A motorized device for retrieving rectangular objects and stacking said objects on a pallet is described. The device includes a conveyor for picking up objects such as hay bales from the ground and a manipulator for taking bales from the conveyor and orienting them either lengthwise or crosswise. The oriented bales are then individually transported to an accumulator in the desired orientation to form a layer. When the layer has been formed on the accumulator, a carriage is translated forward and downward to engage the layer and pick the layer up, moving the carriage and layer of bales rearwardly to deposit them on a pallet. Successive layers are formed in this fashion until a stack of the desired height is disposed on the pallet. The device then may transport the palletized load to a storage or transport area where the load may be moved by forklift truck.Type: GrantFiled: August 29, 1984Date of Patent: August 5, 1986Inventor: Marvin F.
