Abstract: Provided is a gripping portion structure of a gravure plate-making robot in which the accurate gripping of an unprocessed plate-making roll and the positioning accuracy during transfer of the unprocessed plate-making roll to each processing device can be improved by causing a gravure plate-making robot to exhibit a high gripping force when gripping the unprocessed plate-making roll.

Abstract: A staple removal device for removing a staple and wire arrangement from a fence post includes a main body having a first jaw and a second jaw spaced apart from each other. The first jaw and second jaw provide a first and second elongate channel respectively for receiving the wire. Both the first and second elongate channels comprise a closed end in which the wire may be received. A gripping portion is moveably connected to the main body and a lever causes movement of the gripping portion. Beneficially, a first and second block portion is configured at a surface of the main body wherein a side edge of the first and second block portion is substantially in alignment with the closed end of the first and second channel respectively so as to, in use, increase the surface area of the contact region between the staple removal device and the wire.

Abstract: A mechanical gripper being adapted to automatically perform a stable pinch grasp and an encompassing grasp and a method of determining a system geometry thereof. The gripper comprising at least one mechanical finger comprising. The at least one mechanical finger comprising a first phalanx and a second phalanx that are pivotally connected. When a load is applied on a stable pinch grasp region, an actuation mechanism is adapted to allow the second phalanx to translate and allow its contact surface to maintain a constant orientation in order to automatically perform a pinch grasp, when a load is applied on the first phalanx or below the stable pinch grasp region, the actuation mechanism is adapted to allow the second phalanx to pivot and automatically perform an encompassing grasp.

Abstract: A gripping device comprising: a house; at least one gripper configured with at least one claw, the claw being configured with a pair of first phalanxes linked to the house at a first joint, and a pair of second phalanxes linked to the first phalanxes at a second joint; a first actuator arranged on the first joint; a second actuator arranged on the second joint; and a motor configured to enable the first and the second actuators co-operate so as to push the second phalanxes off a gripping substrate, or to push the second phalanxes back to the gripping substrate.

Abstract: A hydraulic orange peel material handling grapple that is attachable to a boom stick on a material handling machine is used for recycling or material handling in grabbing odd shaped objects, unprocessed scrap and scooping up small items and shredded scrap. The grapple includes a central tower having at least four aligned upper and lower mounting ears circumferentially arranged equally distant from each other. A hydraulic cylinder with a ram is mounted to each upper ear. A set of at least four interchangeable pointed-shaped tines are provided for grabbing the odd shaped objections and unprocessed scrap. A set of four interchangeable flat-shaped tines that are used for scooping up small items and shredded scrap are also provided. Each tine has a cylinder ram mount ear on an upper portion of the tine for mounting the cylinder ram and an uppermost mount distal from the tine tip for pivotally mounting the tine to one of the lower frame mounting ears.

Abstract: A transfer ring suitable for use in the manufacture of vehicle tires including a skeletal cylindrical cage which houses an oscillatable circular drive member. The drive member includes a plurality of cam followers disposed about the outer perimeter thereof and which operatively engage respective camming grooves defined in each of a plurality of hinged driven links which are individually hingedly mounted internally of the cage about the outer perimeter of the cage. Each driven link includes an inboard end hinged within the cage and an outboard end having an articulating shoe mounted thereon. The shoes are interconnected to provide like simultaneous substantially equal articulative and rotational movement of the shoes radially inwardly or radially outwardly of the cage upon rotational movement of the drive member and resultant rotational movement of the hinged driven links effected through the cam followers and camming grooves of the driven links.

Abstract: The invention relates to a device for engaging objects, such as heat exchangers of varying sizes. The device includes at least one gripper provided with at least a first and a second gripper arm, at least one of which is movable with respect to the other gripper arm for enclosing an object therebetween; and a driving mechanism connected to at least one of the first and second gripper arms for closing or opening the gripper as needed, wherein at least one of the first and second gripper arms includes a first and a second gripper arm part that are pivotally coupled together, and an adjusting mechanism provided between the first and second gripper arm parts, the adjusting mechanism being arranged for adjusting the angle between the gripper arm parts in dependence on the diameter of the object to be engaged prior to engaging the object.

Abstract: The present invention is a highly-efficient barrel placement device comprised of an attachment plate which attaches to the front of a skid steer loader; tubular support members; and a plurality of barrel pincers with gears that allow the barrel pincers to move in unison with the use of a single hydraulic cylinder. The hydraulic cylinder has hydraulic lines which connect to the auxiliary controls of a skid steer loader allowing the barrel pincers to be controlled to grasp and release traffic barrels from the interior of the skid steer loader.
