Abstract
The invention relates to a vacuum handling device with a suction box (12), a vacuum blower (22), a handling device (16) and a suction unit (20) obturating the suction box and consisting of a suction plate (26) and a suction pad (30). The inventive handling device is further characterized in that the suction unit is provided with suction openings (36) that have a certain flow resistance.
Claims25
Handling device, specifically vacuum handling device having a suction chamber (12) forming a vacuum reservoir, at least one vacuum blower (22), specifically a handling device (16) and a suction unit (20) closing off the suction chamber (20) toward one or several workpieces to be lifted by vacuum, where the suction unit (20) has a suction plate (26) with flow changing means and the suction plate (26) is covered by a flexible suction pad (30) toward the workpiece or workpieces and the suction pad (30) is furnished with suction openings (36) which correspond to the flow changing means, where the suction pad (30) consists of an especially flexible, dense material and the means to change air flow of the suction plate (26) and/or the suction openings of the suction pad (30) have a resistance to flow, characterized in that at least one intermediate pad is interposed between the suction pad (30) and the suction plate (26), also consisting of a flexible material and furnished with through openings which correspond to the suction openings (36).
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the suction unit (20) is bonded to the suction box (12) or is solidly clamped thereto.
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the suction plate (26) has a dished configuration and has a circumferential edge (44) by means of which the suction plate (26) is solidly clamped to the suction box (12).
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the suction pad (30) is configured as a film.
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the suction plate (26) is supported on its back side by means of a flexible pad (68) permeable to air.
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the suction pad (30) is configured in several pieces, and one piece is formed by an air-impermeable, flexible pad (62) which has air passages (64).
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the suction pad (30) has suction openings (36) whose cross sections expand in the direction of the workpiece or workpieces.
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the flexible, dense material is a closed-cell foam.
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the suction pad (30) has a circumferential edge projecting beyond the suction plate (26).
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the suction plate (26) has a circumferential edge projecting beyond the suction pad (30).
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the flow changing means of the suction plate (26) or the suction openings (36) of the suction pad (30) respectively have a regular grid pattern, for example a honeycomb pattern.
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the flow changing means of the suction plate (26) or the suction openings (36) of the suction pad (30) respectively have a grid pattern matching the arrangement of the workpieces.
Handling device, specifically vacuum handling device from one of the preceding claims, wherein a sandwich plate (78) is located between the intermediate pad (82) and the suction pad (30).
Handling device, specifically vacuum handling device from one of the preceding claims, wherein several intermediate pads (82) and/or sandwich plates (78) are furnished and the suction unit (20) is of sandwich construction.
Handling device, specifically vacuum handling device from one of the preceding claims, wherein the flow changing means are a plurality of openings (28), flow resistances and/or flow valves.
Handling device, specifically vacuum handling device from claim 25, wherein the flow valves can be actuated individually or in groups.
