Conveyor device for conveying workpieces, workpiece treatment system and method for conveying workpieces

Abstract

Conveying device (100) for conveying workpieces (102) along a conveying direction (104), comprising: - a workpiece holding device (114) on which one or more workpieces (102) can be arranged; - an acceleration device (132) by means of which the workpiece holding device (114) together with the one or more workpieces (102) arranged thereon can be accelerated from a predetermined starting position (124) of the workpiece holding device (114) along the conveying direction (104), - a braking device (134) by means of which the workpiece holding device (114) together with the one or more workpieces (102) arranged on it can be braked at a predetermined end position (126), and - a positioning device (250) for positioning the workpiece holding device (114) together with the one or more workpieces (102) arranged thereon, which includes a sliding device (252) and / or a locking device (254), wherein the workpiece holding device (114) together with the one or more workpieces (102) arranged thereon is movable by means of the sliding device (252) in a direction opposite to the conveying direction (104), wherein the blocking device (254) is designed to block in a unidirectional manner, so that the workpiece holding device (114) together with the one or more workpieces (102) arranged thereon is movable past the blocking device (254) in the conveying direction (104), but movement of the workpiece holding device (114) together with the one or more workpieces (102) arranged thereon in a direction opposite to the conveying direction (104) is blockable, wherein the workpiece holding device (114) together with the one or more workpieces (102) arranged thereon can be clamped between the blocking device (254) and the sliding device (252), wherein a blocking element (288) of the blocking device (254) is pivotable about a rotational axis (292) when the workpiece holding device (114) moves past the blocking device (254) and is thereby movable out of a conveying path (260), and wherein the blocking element (288) can be pivoted back into the conveying path (260) due to the action of a spring (294) of the blocking device (254) as soon as the workpiece holding device (114) has been moved past the blocking device (254).
