  • Patent number: 9988229
    Abstract: Device for controlling the discharge of Logs outgoing from a rewinding machine, comprising a body (6) placed downstream of a surface (5) along which the logs (3) move in a output direction (F), wherein said body (6) rotates with a predetermined angular speed about an axis (a) parallel to the logs (3) and perpendicular to said output direction (F) followed by the Logs (3). The body (6) has at least one pocket (P) adapted to receive and temporarily housing a log (3) that enters in the same pocket (P) while moving along the said output direction (F). The body (6) rotates about said axis (a) in a direction (G) opposite to the output direction.

  • Patent number: 7296674
    Abstract: Conveyor systems for storage and movement of goods on pallets and slip sheets. The transfer structures enable slip sheet mounted loads to be transferred to a roller conveyor by providing structures that cooperate with wide platen forks of a lift truck. The structures provide roller contact between a portion of the underside of the slip sheet at all times. In other areas there is alternatively contact between a lift truck platen or additional rollers that cooperate in a manner making it possible to move the slip sheet mounted load from the lift truck to an adjacent conveyor system.

  • Patent number: 7152728
    Abstract: The present invention 10 discloses a device for singulating individual logs from groups of logs for linear or transverse processing. The present invention discloses a log singulator having a fully rotatable lifter arm member, i.e., 360 degrees rotatable, which is used to singulate logs from groups of logs. The rotatable axle of the lifter arm may be located above the upstream “V” of the log cradle member. Furthermore, the lifter arm of the present invention will positively push the logs over the top point of the log cradle because it is rounded at the top point, thereby allowing the tip of lifter arm to remain in contact with the log. Lifter arms with 1 to 4 lifter arm tips are disclosed.

  • Patent number: 6779649
    Abstract: A log singulator and associated method for conveying and controllably discharging logs are provided. The singulator has a plurality of rotatable lifters with outwardly-extending arm members that contact the logs with a leading side to convey the logs to successive positions, for example, along a log cradle structure. The logs are conveyed to a discharge surface, which can be disposed at a declined angle so that the logs thereon tend to roll toward a discharge position. Discharge lifters, which are configured to discharge the logs from the discharge surface, have arm members that define angled cam surfaces on their trailing sides. The cam surfaces contact and retain the logs on the discharge surface until the logs reach the predetermined discharge position. Thus, the logs can be controllably discharged, for example, at a desired time.

  • Patent number: 6637581
    Abstract: This invention provides log singulators which allow for the vertical singulation of piles of logs fed from typical in-feed log decks, so that these logs may be fed individually to typical out-feed conveyors. Devices provided by this invention may be high-speed singulators occupying minimal floor space area. Singulators provided by this invention comprise arcuately oscillating lifting devices (“primary lifting devices”), preferably rotating synchronously in opposite directions. Preferably, these singulators elevate logs against vertically successive barriers. These barriers are shaped so that only one of either a largest log or a smallest log, which it is expected that the singulator should handle, can rest on the primary lifting devices and be carried upward at a time.

  • Patent number: 6431345
    Abstract: A high speed board feeder for transferring boards from an infeed conveyor onto a secondary conveyor. The boards on the infeed conveyor are transported in an edge to edge configuration against a fixed stop. Hold down mechanism is provided to secure the boards in the desired orientation. A cam member timed to the secondary conveyor has lobes that engage and lift the board that is against the positive stop. The lobes lift the board upward and over the positive stop. The board is forced onto the secondary conveyor by the conveying force of the preceding boards. The board is placed on the secondary conveyor between successive drive lugs. A pivotal stop arm is provided to interrupt the feeding of boards from the infeed conveyor to the secondary conveyor.
