It is proposed that, during the receiving and/or outputting, the plate (14) carries out a non-linear compensation movement relative to the drum (12) with a radial movement component.
METHOD AND APPARATUS FOR DEPOSITING DISCRETE ELEMENTS ON A SUPPORT ELEMENT
A method and apparatus for depositing discrete elements on a support element. The discrete elements may be separated from each other or joined to form a continuous web. The discrete elements are fed into a pick-up station defined at a rotor which includes circumferentially adjacent pick-up members. Each discrete element is associated with a respective pick-up member having a first orientation with respect to a respective second axis of rotation. Each pick-up member is moved along the rotation direction towards a release position downstream with an at least partially accelerated or decelerated motion. Each pick-up member is rotated about the respective second axis of rotation until it takes, at the release position, a second orientation. Each discrete element is released on a support element at the release position. Each pick-up member is subsequently moved towards the pick-up station with an at least partially decelerated or accelerated motion.
METHOD AND APPARATUS FOR SEPARATING BLANKS
A method for separating blanks includes continuous conveying of a sheet metal strip in a transport direction to a laser cutting station, concurrent cutting of the sheet metal strip by at least one cutting laser, wherein a cut sheet metal strip is formed from successive sections of the same cutting geometry, transporting the cut sheet metal strip on a first conveyor belt in the transport direction, taking over the cut sheet metal strip from the first conveyor belt, transporting the cut sheet metal strip in the transport direction, separately ejecting the at least one residual blank of each section, transporting the at least one blank of each section into overlap with a second conveyor belt and ejecting the at least one blank from the suction conveyor, and transporting the blanks ejected one after the other from the suction conveyor horizontally in the transport direction to a collecting station.
System, apparatus and method for damping and stabilizing automation picking and stacking
An apparatus for picking a product, including: at least one vacuum cup including at least one axis passing through the at least one vacuum cup; and at least one damping device surrounding at least a portion of the at least one vacuum cup in a radial direction orthogonal to the at least one axis. The at least one vacuum cup is arranged to create negative pressure and adhere, with the negative pressure, the at least one sheet of material to the at least one vacuum cup. The at least one damping device is arranged to contact the at least one sheet of material to limit displacement of the at least one sheet of material with respect to the at least one vacuum cup.
METHODS AND APPARATUSES FOR SEPARATING AND POSITIONING DISCRETE ARTICLES
Methods of separating and positioning discrete articles formed from a continuous length of articles are provided. The methods may comprise the steps of receiving a first portion of the continuous length on a first head in a receiving position of an orbit about a first rotational axis and receiving a second portion of the continuous length on a second head in the receiving position of the orbit about the first rotational axis. The methods may comprise providing a laser system configured to produce and direct a laser beam, and ablating a portion of the continuous length of articles intermediate the first head and the second head with the laser beam to separate the first portion of the continuous length of articles from the second portion of the continuous length of articles, thereby forming a discrete article on the first head.
AUTOMATED FABRIC PICKING
Aspects of automated fabric picking are described. In one embodiment, a system includes a textile cutter including a tabletop upon which textile panels can be cut out from a textile sheet, a textile panel picker, and a computing device. The textile panel picker includes a flexible transport tube, a transport tube transfer arm to position the flexible transport tube over the tabletop and the textile panels, a textile hopper to collect the textile panels, and a pneumatic pump assembly to evacuate air from the textile hopper and through the flexible transport tube. The computing device identifies and tracks the textile panels on the tabletop, directs the transport tube transfer arm to position the flexible transport tube over the textile panels, and directs the pneumatic pump assembly to generate suction to pull the textile panels through the flexible transport tube and into the textile hopper.
