Disclosed is a device for conveying workpieces through a press working line or a transfer molding press. The conveying device is embodied as a telescopic feeder and is designed such that a jib which can be displaced in a longitudinal direction is mounted or guided by means of guiding carriages that travel along. An adequate entraining mechanism is provided in order to ensure the traveling motion of the guiding carriages.

Conveying device

The invention relates to an articulated arm transport device which is especially provided for the automation of large component transfer presses. Said articulated arm transport device is characterized by a kinematics and design that do not require any additional clearance between the press rams and pillars and that permit an introduction or extraction of workpieces even with a small clearance between the upper and lower tool. The articulated arm transport device is mounted above the workpiece transport plane on the press stands. The articulated arm part linked with the cross-member is shorter than the articulated arm part and makes a pivoting movement substantially above the common pivot. A lifting and/or pivoting movement can be carried out by means of controlled lift drives that are functionally linked with transmission means.

Articulated arm transport device

A transporting apparatus, in particular a 3-way transfer means, for transfer presses, in the case of which, for horizontal movement, linear drives are attached and actuated such that, along with a compact construction, the linear drives allow the gripper rails to be changed straightforwardly during tool-changing operations.

Apparatus for transporting workpieces in presses

A transfer system provided, in particular, for multi-stage presses for large components is distinguished by a favorable design with a low moving mass and allows large transporting steps. By the regulation of 2 stationary drives both in the direction of rotation in relation to one another and in the rotational speed, it is possible to realize all desired traveling curves in one plane. A straightforward construction makes possible a cost-effective, modular solution for a highly dynamic transfer system.

Horizontal transporting system

The invention proposes a transporting apparatus for transporting single or double workpieces through processing stations of presses, in which apparatus up to 9 degrees of freedom are integrated in the transporting system. Necessary changes in position for, for example, feeding into dies can take place directly by way of the transporting apparatus. It is possible to dispense with intermediate set-down locations or orienting stations.

Flexible transporting apparatus for presses

An exchanging device is proposed for the parts-specific accessories and especially for the suction crossarm in a press, press line, multiple-die press for large parts or the like in order to make possible a good accessability of the press area, the exchanging device in the parked position is below the passable covering.

Tool-exchanging device for presses

A transport system provided in particular for large-component transfer presses is distinguished by a design with a low width and, nevertheless, permits large transport steps. By controlling two drives in the direction of rotation in relation to each other, all desired travel curves in one plane can be realized. As a result of the simple construction, a cost-effective solution is achieved for a highly dynamic transport system.

Transport system

An articulated-arm transport system, provided in particular for the automation of press lines and large-component transfer presses, is distinguished by a design which permits components or workpieces to be inserted or removed even when there is a small clearance between an upper and lower tool.

Articulated arm transport system

A transfer drive is proposed for a press and in particular for a forging machine, in which the intention is to dispense with guides which are sensitive to dirt. For this purpose, the gripper rails are suspended on a hinged-rod arrangement with a three-axis guide system.

Transfer drive for a press

A transport system for transporting workpieces through machining stations of a press device. The transport system includes at least one independent transport device dedicated to each machining station, the transport device being effective for receiving and transporting a workpiece in at least one of a 2-axial and a 3-axial transport motion. The transport system includes a longitudinal transport device for effecting a horizontal longitudinal motion of the workpiece in a transport direction of the workpiece and having a horizontally extending extension arm for transporting the workpiece between machining stations. The extension arm includes guides, and a transport slide for transporting the workpiece in the transport direction. The transport slide is disposed on the guides for being longitudinally movable thereon and has coupling device thereon for coupling one of a suction beam and a gripper arrangement to the extension arm for effecting a reception of the workpiece by the longitudinal transport device. The transport system further includes: a lifting mechanism operatively connected to the longitudinal transport device for effecting a vertical motion of the workpiece; and a closing-opening mechanism operatively connected to the longitudinal transport device and the lifting mechanism for effecting a transverse motion of the workpiece with respect to the transport direction thereof.

A transport device for transporting workpieces through machining stations, especially of a multiple-die press, is proposed, in which the supporting or gripper rails can perform a 2-axial and/or 3-axial motion in the longitudinal direction of the press, in the vertical direction and in the transverse direction relative to the longitudinal direction of the press. For the performance of the lifting motion and of the transversely directed closing/opening motion of the supporting or gripper rails, a separate transport unit is provided, which supports the supporting or gripper rails using a transversely displaceable lifting column.
