  • Patent number: 11225383
    Abstract: A stripper system for belt conveyors. The system includes an adjustable, spring-mounted system support running transversely to the direction of travel of the belt conveyor, on which stripper blocks made from an elastomer are interchangeably secured next to one another. The system support is suspended on both sides of a tripper pulley by a support mounting so that the support system can rotate about a support axis of rotation, which impresses, by a spring device, a predefinable torque directed counter to the rotational direction of the tripper pulley. Such axis allows the system support to rotate such that it together with its stripper blocks can swing away. The spring device has an adjusting spring, a damper spring coupled thereto, and a spring bolt. Both springs are connected to the support mounting, and the spring bolt includes a section that initially actuates the damper spring when it is determined that the adjusting spring has travelled a prescribed distance.

  • Patent number: 11208267
    Abstract: A system, and associated method, for launching and delivering separated food product in organized groups to a robotized packaging station for the product. The system initiates the delivery via a metered hopper of food product delivering the product to a launch V-belt that aligns the product end to end. A successive singulator belt, positioned adjacent to and receiving product from the launch belt, further organizes the product into a single file alignment. An optional separator belt may follow the singulator belt to create gaps between successive product units. The product is then delivered to a pick belt for product to be provided to the packaging robot. The system product information is from a single (per product delivery line) sensor, enabling intergrated end-to-end control from hopper to robot, and a nearly continuous motion of said pick belt.

  • Patent number: 11192726
    Abstract: A control system for an automated singulation system is provided. The control system detects a presence of a first item on a first conveyor and detects a presence of a second item on a second conveyor while the first item is present on the first conveyor. The second conveyor transfers items onto the first conveyor and is at a lower height than the second conveyor. The first conveyor is oriented perpendicularly with respect to the second conveyor. In response to detecting the presence of the second item, a location of the first item along a length of the first conveyor is determined. The first conveyor and the second conveyor are controlled based at least on the location of the first item.

  • Patent number: 11186440
    Abstract: A parts accumulating section includes a cylindrical center member; and a hose helically wrapped around the outer periphery of the cylindrical center member, and connecting two predetermined steps of a parts production line to each other. The hose has an inner diameter dimension which enables parts to pass, in a predetermined attitude, through the hose with only a respective one of the parts disposed in the hose in the radial direction of the hose. A vibration generating section applies torsional vibrations to the parts accumulating section so that the parts are fed through the hose. The parts discharged from the upstream step are accumulated in the hose in the same order as they are handled in the upstream step. The parts are fed through the hose without generating surface damage to the parts due to their collision against each other, and are supplied to the downstream step.

  • Patent number: 11180323
    Abstract: Systems and methods for providing gaps in article or package processing. In some embodiments, the system can include a conveying path along which a first advanced article and a second advanced article can be advanced. The system can further include a first stop location and a second stop location. The first stop location can include movable fingers that are configured to raise to stop the advance of the articles and then lower at specific times to allow the articles to advance with specific distances between the articles. Additionally, the system can include a paddle that also raises and lowers. The paddle lowers to stop an advancing article again, and in doing so, front-end registers the article. Then the paddle can raise to allow the package to advance again along the conveyor.
