Abstract: Modular transfer band assemblies and systems are provided. The modular transfer band assemblies may include a frame, pulleys supported by the frame, and a belt provided around the pulleys. The belt is configured to be driven to transfer an article off of a main conveyor line having rollers for conveying the article. The removable belt module is configured to be engaged and disengaged from the main conveyor line without the use of tools as a single, self-contained unit. Modular transfer band assembly systems may include the modular transfer band assembly and a support structure, wherein the modular transfer band assembly is removably attached to the support structure.

Abstract: An non-contact article rotating device is disclosed that rotates articles without impacting or contacting the article other than the bottom of the article. The device is designed to accept a stream of articles with minimum gaps between them, and rotate only those that are programmed to be rotated. The device accepts any combination of rotated and non-rotated articles and can rotate them through angles up to and through 360 degrees. One embodiment of the disclosed device uses only one single-speed drive motor and pneumatic components to operate two conveyor roller sections. While one conveyor roller section maintains a constant speed, the conveyor rollers of the second conveyor roller section are sequentially braked and unbraked to rotate an article that is positioned partially on the first conveyor roller section and partially on the second conveyor roller section. The difference in speeds between the two conveyor sections rotates the article.

Abstract: An object detecting device for detecting the existence and general placement of an object residing upon a surface. A preferred embodiment of the invention uses at least one laser measuring scanner operated positioned by a servo motor to allow the laser measuring scanner to generate signals related to the placement of an object on a surface. Those placement signals are then processed by a computer to make a two or three dimensional determination of the object in coordinates that show the object's location in relation to another device such as a robotic depalletizer that can then be moved into position near the object to allow removal of the object by the robotic depalletizer.

Abstract: Embodiments are directed to conveyor systems and methods which can accommodate negative gap between articles (e.g., cartons, packages, products, etc.) conveyed upon a sortation conveyor. Negative gap is attained by placing articles side-by-side upon a conveyor (as opposed to single file) so that the trailing edge of a leading article can lag behind the leading edge of a trailing article in the movement direction. In one embodiment, a conveyor system comprises a main conveying line providing a conveying surface configured to carry articles, a plurality of pusher elements associated with the main conveying line, a controller configured to assign pusher elements to articles being conveyed and to determine whether two articles received can be placed next to one or more of the same pusher elements in an overlapping relationship, can be placed to receive contact from immediately adjacent pusher elements, or should be spaced by one or more pusher elements.

Abstract: Sortation conveyor apparatus and methods for selectively diverting articles from a primary conveying surface onto branch lines are provided. In one embodiment, the apparatus comprises a control system for selectively operating activating elements. The control system is configured to assign two or more pusher elements to each article to be diverted, and to ensure proper diversion of articles when adjacent articles are spaced apart on the primary conveying surface by a distance which is less than the width of an individual pusher element. In one embodiment, diversion is provided by a single activating mechanism for a plurality of pusher elements per branch destination, and by rotating the article during the initial diverting movement and contact with the pusher elements.

Abstract: An apparatus and method of bundling bulk items, such as for example papers and magazines, that includes applying a double-sided label to the top and bottom of the material stack, compressing the material stack, applying two binding materials around the material stack, and then relieving the compression on the material stack to allow the binding material to maintain the compression on the bundled material. The binding material, including the double-sided label, can be automatically removed from the bundled material by removing the binding material from the stack of materials and vacuuming the binding material away from the stacked material.

Abstract: A merge conveyor defines a travel pathway for moving cargo. A tail pulley has a first rotational axis which is perpendicular to the travel pathway. First and second nose bars are parallel and spaced and are disposed at an angle with respect to the travel pathway. A drive pulley has a second rotational axis which is parallel with the travel pathway. A snub pulley has a third rotational axis which is parallel with the first rotational axis. An endless belt is sequentially routed over the tail pulley, the first nose bar, the drive pulley, the second nose bar, and the snub pulley. The endless belt extends directly from the second nose bar to the snub pulley and then directly to the tail pulley.

Abstract: A conveyor system having a frame, a drive sprocket rotatably mounted to the frame, and a tail pulley rotatably mounted to the frame opposite the drive sprocket. A continuous belt engages with the drive sprocket and tail pulley with a catenary take-up arrangement having an upper conveying portion and a lower return portion. A snub idler may be engaged with the return portion of the belt so that the belt properly engages the drive sprocket. A motor couples with the drive sprocket, the motor being capable of driving the belt in forward and reverse directions. A take-up device engages with the return portion of the belt so that the belt is capable of running in forward and reverse directions.
