A conveyor for buffering products includes a first helical conveyor having a first conveyor input and a first conveyor output and a second helical conveyor having a second conveyor input and a second conveyor output. The first conveyor output is coupled to the second conveyor input and the second conveyor output is coupled to the first conveyor input. A loading station and a discharging station are configured to load and discharge products to and from the conveyor. A single conveyor belt follows the helical tracks of the first and second helical conveyors.

An overhead conveying device includes a conveying device mounted on supporting framework. The supporting framework and the conveying device form a conveying corridor. At least one securing element can be arranged at an input point and/or output point of the supporting framework, and the securing element can be moved between a securing position and an opening position. The securing element functions in the securing position as fall protection and at least partially blocks the initial cross-section and/or terminal cross-section of the conveying corridor. In the opening position, the securing element releases the initial cross-section and/or terminal cross-section of the conveying corridor for the transport of components with the help of the conveying device.

Method for aligning single elements (4) arranged in receiving pockets (3) of a transfer means (2), wherein the receiving pockets (3) are arranged in rows and are moved stepwise from one station into a following station, comprising the following steps: determining in which receiving pockets (3) incorrectly aligned single elements (4) are present, ejecting the single elements (4) determined as incorrectly aligned from the associated receiving pockets (3), turning the ejected single elements (4) by 180, and re-inserting the turned single elements (4) into the associated receiving pockets (3).

A method and apparatus for cyclically shielding a work chamber opening (25) when loading and unloading workpieces using a conveyor device (10) that passes through the work chamber opening. A first shielding element (21) is placed at a workpiece loading station (11.1), and a second shielding element (22) is placed behind a second workpiece placement location (11.2), as viewed in the conveying direction. When the first workpiece is loaded into the work chamber (20), the first shielding element (21) is placed at or in the work chamber opening (25) by advancing the conveyor device (10). The first shielding element (21) is then removed from the work chamber opening (25) and placed behind the second shielding element (22). These steps are repeated with subsequent workpiece placement locations (11.2, 11.3, . . . ) of the conveyor device (10) and with respective cross-over changes of the shielding elements (21, 22).

There is provided an electronic device transfer apparatus which has an excellent capacity of transferring DUTs between trays. An electronic device transfer apparatus, which transfers DUTs between trays, includes a device conveying unit. The device conveying unit includes a plurality of shuttles which hold the DUTs, an endless first guide rail which guides the shuttles, and first to third feeders which move the shuttles on the first guide rail. The shuttles are movable on the first guide rail over the entire circumference of the rail.

A long-bar handling apparatus that delivers a desired size and shape of long-bar quickly and efficiently for shearing, bending, or further processing. The long-bar is loaded in slots in multiple rotating disk plates. A slot opening and closing mechanism, such as a pivot arm, is utilized to prevent loaded long-bar from falling out of slots during portions of rotation. The slot opening and closing mechanism opens on the top portion of rotation for loading and removing the long-bar for processing.

An apparatus for receiving, from a wide container stream upstream from the apparatus, single-lane container streams and creating package units of containers includes a separating and/or combining unit, application elements, and a linear transporter. The unit separates and/or combines containers to form partial packaged units that are then combined into a package unit. The application elements are disposed so that at least one container of a package unit has, on a contact surface thereof, adhesive or glue. The linear transporter comprises transport elements circulate along a guide element, and a controllable drive. Each transport element of the linear transporter comprises as many head guides as there are containers in the package unit, each of which is axially movable or rotatable relative to the transport element.

A conveyor run for moving goods to two or more destinations can be used to move a first fraction of the goods to a first destination and a second fraction of the goods to another destination. A drive motor coupled to a conveyor portion is reversible to enable the conveyor run to move goods in either direction along the conveyor run. An adjustable gate includes a rotatable sleeve with an opening that is positionable relative to conveyor portions between which the adjustable gate is connected. The rotatable sleeve rotates relative to the adjacent conveyor portions to position the opening to set the fraction of the goods that pass from an upstream conveyor portion to the downstream conveyor portion and to set the fraction of the goods that drop from the conveyor run through the opening.

A surface treatment plant for vehicle bodies having a first treatment area which comprises a first conveyor system enabling a vehicle body to be conveyed through the first treatment area, and a second treatment area which includes a second conveyor system enabling the vehicle body to be conveyed through the second treatment area. A transfer device enables the vehicle body to be transferred from the first conveyor system to the second conveyor system. The transfer device includes supports which engage on regions of the vehicle body and at least one is arranged in particular on the highest point of the horizontal and the vehicle body is oriented roof upwards. Also a method for conveying vehicle bodies through a surface treatment plant.

The invention relates to a transport device (1) for conveying a product, comprising a stationary running rail (2) which extends along a longitudinal axis (3); a cart (6) with a height axis (5) which is perpendicular to the longitudinal axis (3), said cart being guided on the running rail (2); guiding rollers (7) which are arranged on the cart (6), can be rotated about rotational axes (8) perpendicular to the longitudinal axis (3), and roll on the running rail (2), wherein the rotational axis (8) of each guiding roller (7) intersects the same straight line (9), which is perpendicular to the longitudinal axis (3); and a compensating device for compensating for a yaw moment (M) of the cart (6) about the height axis (5), comprising multiple magnetic coils (12) arranged along the running rail (2), at least two ferromagnetic or permanent magnetic counter elements (11) which are arranged on the cart (6) and which are arranged on both sides of the running rail (2), and a control device (18) for controlling the magnetic coils (12) such that the counter elements (11) can be simultaneously pushed away from the running rail (2) in the direction of a transverse axis (4), said transverse axis (4) being defined as perpendicular to the longitudinal axis (3) and perpendicular to the height axis (5).
