A transfer mechanism includes a rail, first and second tables on the rail, first and second arms each having a base pivotably supported by the first and second tables, respectively, and first and second drive mechanisms that move the first and second tables along the rail, respectively. The first and second arms are pivotaly connected to each other at a position between a tip side and a base side. Tip side portions of the first and second arms than a connected portion of the first and second arms serve as fingers for holding a workpiece. The first and second drive mechanisms independently move the first and second tables, respectively. A relative movement of the first and second tables causes the first and second arms to operate a clamp/unclamp operation. A coordinated movement of the first and second tables causes the first and second arms to perform an advance/return operation.

A method and a device for producing bipolar plates for fuel cells. A bipolar plate is formed by joining an anode plate to a cathode plate, wherein the anode plate and the cathode plate are formed by forming a substrate plate.

In order to provide a cost-effective and automated method, it is proposed that a plate already provided with a reactive coating or catalyst coating, which is transported, automatically driven, via a transport device from the forming device to the joining device, is used as substrate plate.

Linear conveyor for transferring workpieces between two consecutive positions in a throughput direction, including at least one axis extending in and linearly displaceable to the throughput direction, and a slide, disposed on and displaceable along each axis, and to which a carrier element for accommodating the workpiece is attached, each axis being telescopic and including a first axis element displaceable relative to the base, and a second axis element displaceable relative to the first axis element, on which slide is displaceably disposed, and a coupling for coupling of displacement movements of the first axis element, second axis element and slide with each other, such that when the first axis element is displaced relative to the base the second axis element is displaced relative to the first axis element and the slide relative to the second axis element in the same direction of displacement.

A workpiece conveyance device is used for a pressing device. The workpiece conveyance device includes a support member supporting a holding component usable to detachable hold a workpiece, a lever unit including a first lever portion and a second lever portion, a lever unit support body supporting the lever unit, a first lever support portion provided to the lever unit support body, and a second lever support portion provided to the lever unit support body. The second lever portion is provided between the first lever portion and the support member. The second lever portion is rotatably linked to the first lever portion. The lever unit pivotably supports the support member. The first lever support portion pivotably supports the first lever portion. The second lever support portion slidably and pivotably supports the second lever portion.

A pendular handling system for handling parts in a press line may have two articulated robots arranged on opposite sides with respect to the central vertical plane of the press line, each robot having at least four rotational axes in series between a robot base and a robot wrist, and each robot being mounted with the first axis horizontal and perpendicular to the press line flow direction, a first arm of each robot can swing in a vertical plane in the press line flow direction.

A workpiece conveying apparatus includes: a conveying table including a workpiece supporting mechanism; a first arm and a second arm each having one end pivotally coupled to the conveying table; a first moving unit coupled to another end of the first arm; a second moving unit coupled to another end of the second arm; and a posture control unit configured to control a posture of the conveying table through control of an angle between the conveying table and one of the first arm and the second arm, in which the first and second moving units are movable by a moving mechanism in a workpiece conveying direction, in which the conveying table is lifted up and down through a change of an interval between the first and second moving units, and in which these moving units are moved in the same direction to convey the workpiece.

A crossbar support assembly that supports a crossbar includes a support post, a bracket, a riser, and a lock assembly. The bracket is secured to a distal end of the support post. The lock assembly is configured to releasably secure the riser to the bracket. The lock assembly includes a locked configuration and an unlocked configuration. In the locked configuration the riser is inhibited from moving with respect to the bracket. In the unlocked configuration the riser is permitted to move with respect to the bracket. The crossbar support assembly may include an adjustment assembly that adjusts a position of the riser with respect to the bracket when the lock assembly is in the unlocked configuration.

A workpiece transport device is downsized. A workpiece transport device includes: a pair of upstream-side end shaft and downstream-side end shafts disposed apart from each other in a transport direction that is a direction of transport of a workpiece, an upstream-side drive shaft disposed between a pair of upstream-side end shaft and downstream-side end shafts in the transport direction, an upstream-side drive belt wound around the upstream-side drive shaft and the upstream-side end shaft, and a transport belt wound around the pair of upstream-side end shaft and downstream-side end shaft. Driving force for transporting the workpiece is transmitted to the transport belt through the upstream-side drive shaft, the upstream-side drive belt, and the upstream-side end shaft in this order.
