Patent number: 8500181Abstract: A suction lifter comprises a suction cup to be placed against a fixing surface and having a deformable suction disc, the suction lifter being designed for forming a hollow space subject to a partial vacuum between the suction disc and the fixing surface, wherein the suction disc is arranged between the suction cup and the fixing surface, wherein the suction cup further has a circumferential cup rim surrounding the hollow space, and wherein a circumferential supporting area of an upper side of the suction disc facing the cup rim is supported against the cup rim under a vacuum condition. The suction cup rim and/or the suction disc rim are provided with projections which under a vacuum condition of the suction lifter and under a shearing force exerted on the suction disc impede a lateral displacement of the suction cup rim with respect to the suction disc rim.Type: GrantFiled: September 4, 2009Date of Patent: August 6, 2013Assignee: Bohle AGInventors: Heinrich Ostendarp, Kathrin Weidenfeller, Lutz Strehlow

Publication number: 20130106127Abstract: A passive universal gripper includes a mass of granular material encased in an elastic membrane. Using a combination of positive and negative pressure, the gripper can rapidly grip and release a wide range of objects that are typically challenging for conventional universal grippers, such as flat objects, soft objects, or objects with complex geometries. The gripper passively conforms to the shape of a target object, then vacuum-hardens to grip it rigidly; later using positive pressure to reverse this transition-releasing the object and returning to a deformable state. The apparatus and method enable the fast ejection of objects from the gripper, as well as essentially instantaneous reset time between releasing and gripping.Type: ApplicationFiled: April 14, 2011Publication date: May 2, 2013Applicant: CORNELL UNIVERSITYInventors: Hod Lipson, John R. Amend, JR., Heinrich Jaeger, Eric Brown

Publication number: 20130082474Abstract: A bellows 10 is configured for connection to an end effector of a robot and includes a valve 28 supported in the interior space of the bellows. A flow of low pressure air is induced from inside the bellows into a vacuum plenum 24 for retrieving a work product by the open end 16 of the bellows. High pressure air is moved through a conduit 50 into the valve to terminate the flow of low pressure air and terminate the suction applied by the bellows to the work product.Type: ApplicationFiled: August 27, 2012Publication date: April 4, 2013Applicant: AMF Automation Technologies, LLC, d/b/a AMF Bakery SystemsInventors: Roland Lomerson, JR., Michael W. Norton

Publication number: 20130082475Abstract: A vacuum suction apparatus is equipped with a body having a supply port, and a pad provided on a lower portion of the body to which a workpiece can be attracted under suction. The pad is constituted from a base plate accommodated in a space of the body, a flexible intermediate plate provided on a lower portion of the base plate, and a suction sheet body disposed on a lower portion of the intermediate plate and having a sheet that attracts the workpiece under suction. In addition, the base plate, the intermediate plate and the suction sheet body are stacked along an axial direction of the body. The rigidity of the base plate is highest, whereas the rigidities of the intermediate plate and the suction sheet body are lower in this order, and the flexibilities thereof are greater in this order from the base plate.Type: ApplicationFiled: September 10, 2012Publication date: April 4, 2013Applicant: SMC KABUSHIKI KAISHAInventors: Yoshihiro FUKANO, Shuzo Sakurai, Masahiko Someya

Publication number: 20130034420Abstract: A gripper grasps irregular and deformable work pieces so as to lift and hold packaged, processed, or raw, and manipulate the work pieces for the purpose of material handling, assembly, packaging, and other robotic and automated manipulative functions. A vacuum is induced at multiple points through a flexible gripping hood to provide lifting force to, and facilitate rapid movement of, work pieces. An array of lighting devices and a double ring array of segmented mirrors provide uniform illumination to ensure accurate positioning of the gripping hood with respect to the work piece to be manipulated.Type: ApplicationFiled: October 11, 2012Publication date: February 7, 2013Inventor: Preben K. Hjørnet

Patent number: 8267367Abstract: The present invention relates to a vacuum pad device used in a vacuum transport system. The pad device includes a housing, a pad unit connected to the housing through a ball joint such that the pad unit is rotatable, and a piston arranged in the housing and controlling the rotation of the pad unit. The pad unit is bonded to an object at a desirable rotation angle, and controlled such that the rotation angle is fixed by the movement of a piston operating via compressed air. Consequently, the object can be transported in an accurate and safe manner. Preferably, the vacuum pad device of the present invention further includes a vacuum pump arranged in the housing unit the piston.Type: GrantFiled: March 16, 2009Date of Patent: September 18, 2012Assignee: Korea Pneumatic System Co., Ltd.Inventor: Ho-Young Cho
