Abstract:
System and methods for manipulating and sorting of objects being moved along a conveyor are disclosed, whereby control of the object is achieved through the application of one or more of vacuum, impaling, or mechanical grasping. One embodiment is directed to a robotic arm and vision detection system operable for detecting a target object to be grasped from a stream of objects being moved on a conveyor, and moving a suction head into position over the target object that has been detected on the conveyor, the suction head having a flexible cup section disposed at a distal end thereof, the vacuum item pick-up system/method using high subsonic air flow (e.g., on the order of 60 scfm or more) through a suction cup having a flow opening area large enough that an airflow of 60 scfm does not result in an airspeed exceeding Mach 0.2 under standard conditions of temperature and pressure, and further having a flow opening area whose ratio to cup opening area falls between 0.36 and 1.44 for applying a desired vacuum suction force for grasping the target object. Either as a primary grasping mechanism, or as an optional supplemental grasping mechanism, a piercing mechanism may be inserted into the object and used to manipulate the object in space. Alternate systems/methods for manipulating and sorting objects via hitting, flicking, or pushing are also disclosed.
Abstract:
The present invention discloses a sucking disc, including a sucking disc body; there is a chamber with a circular cross section inside the sucking disc body, and the chamber has a closed end surface and an opening end surface, the opening end surface is formed to be an end surface for absorbing an object, and tangential nozzles are disposed on the wall surface of the chamber. The sucking disc further includes an annular separator plate and some pads; pads are disposed apart from each other on the periphery of the bottom surface of the sucking disc body and the upper surface of the annular separator plate is fixedly attached with the periphery of the bottom surface of the sucking disc body via the pads; a partial area of the annular separator plate is covered by the pads, a fixed channel from the annular separator plate to the periphery of the bottom surface of the sucking disc body is formed by the separations between the pads; and the interior of the chamber is communicated with the ambient via the fixed channel. According to the present invention, an object with soft, rough and uneven surface can be sucked with small required air consumption, the influence of the softness or roughness of the object on the suction force is small.
Abstract:
The present invention relates to a vacuum gripper device used in a vacuum transfer system. The device of the present invention includes a vacuum pump that is directly embedded in a negative pressure chamber of a gripper main body, wherein the gripper main body is designed with a configuration for supporting and operating the vacuum pump, such as a first hole and a second hole connected to an inlet and an outlet of the vacuum pump. Here, the vacuum pump is preferably supported by a fixing block provided inside the negative pressure chamber. The present invention does not cause any vacuum loss during the operation of the vacuum pump, and forms a desired level of vacuum pressure quickly. In addition, the vacuum gripper device of the present invention can be designed compactly and safely although the device includes the vacuum pump.
Abstract:
A vacuum generator driven by compressed air and arranged to supply vacuum to a vacuum gripper element, wherein a chamber (6) is associated with the vacuum generator and arranged to be brought in flow connection (9) with the vacuum gripper element via a valve (15) which is actuated by overpressure accumulated in the chamber to open the connection (9) to the vacuum gripper element in order to discharge the overpressure to the vacuum gripper element in result of interruption of the compressed air flow (P). The vacuum generator is characterized in that the chamber (6) in addition includes a flow connection (11) with the ambient atmosphere, and in the additional flow connection (11) a one-way valve (10) which is arranged to open the connection (11) with the atmosphere in result of the air pressure in the chamber (6) falling below the atmospheric pressure.
Abstract:
The invention provides a suction gripper, the drive means of which consists of a compressed-air source and which is disposed, respectively, that a connectable drive means can consist of a compressed-air source. The suction gripper according to the invention has a central channel in a casing which preferably is arranged along the longitudinal axis of the casing. The central channel has a first opening opened up by a convex surface around the central channel. The central channel adjacent to the convex surface has its smallest cross-section and from this broadens towards the second opening opposite the first opening.
Abstract:
A method and an apparatus for the manipulation of objects are provided, comprising steps of creating a low pressure zone between a plate with a gas-flowing surface and an object to be manipulated. This gas is forced to flow between the surface of the plate and the object. The low-pressure zone created between the surface and the object results in a force acting on the object and towards the plate. By moving the plate the object is moved. The method and apparatus are easy to implement and provide contact manipulation of objects.
Abstract:
A Bernoulli Effect pick-up device (1) for the handling of products (20) comprises a surface (4) adapted such that gaseous fluid flow across said surface (4) provides a pick-up force to be generated, by the Bernoulli Effect, in a direction towards said surface (4), and a conduit (2) for the supply of the gaseous fluid. The conduit (2) has an outlet opening (5) at the surface (4) and is adapted to supply gaseous fluid in a direction opposed to the pick-up direction. The outlet (5) of the conduit (2) is associated with a deflector (9) for directing gaseous fluid across the surface (4) and preventing direct impingement of the fluid on a product (2) that has been picked-up by the device (1). The product (20) may for example be a slice of a foodstuff, e.g. tomato or hard-boiled egg.
Abstract:
In a contact-free plate conveyor including an arrangement of nozzles each having a cup-like shape widening to a planar rim thereof, means are provided for supplying air under pressure to the nozzles such that the air flow toward and through a gap formed between the rims of the cups at high speed generates a vacuum between the cup rims and the plate so as to hold the plate at a predetermined distance from the nozzle arrangement.
Abstract:
The present invention relates to a non-contact holder for substantially planar workpieces, particularly suited for holding thin workpieces without substantial distortion. The present invention includes a cylindrical chuck having a gas inlet orifice positioned at an oblique. The introduction of pressurized gas creates a vortex and vacuum attraction holding a wafer in close proximity to the chuck while the gas exiting from the chuck prevents contact between wafer and chuck. Small diameter chucks located in close proximity help the present invention avoid distortion when processing very thin workpieces. The gas exiting from the chuck of the present invention exits preferentially in a certain angular direction. Chucks are arranged on the wafer holder such that exiting gas is preferentially directed radially towards the periphery of the holder and that exiting gas is directed between adjacent chucks, not directly at another nearby chuck. Chucks on the periphery of the holder are positioned have the gas exiting therefrom towards the periphery of the holder and overlapping the gas flow from immediately adjacent chucks. Chucks on the periphery of the holder are located as close together as feasible. The combination of overlapping gas flow and close proximity creates a gas shield on the boundary of the wafer holder.
