  • Patent number: 8915694
    Abstract: Disclosed examples relate to loading devices for loading bars for machining in machine tools. A disclosed example loading device is adapted to move a bar from a starting position to an end position and to feed the bar from the end position to the machine tool, comprising a rest portion for supplying the loading device with at least one bar lying on the rest portion in the starting position, and a movable transport for transporting the bar from the starting position to the end position. The transport is adapted to transport the bar downward in a downward movement due to its gravity along a downwardly inclined guiding portion, the bar being supported by a first support portion of the transport.

  • Patent number: 7819621
    Abstract: In order to separate rod-shaped bodies from a bundle of bodies, the surface of an uppermost body in the bundle is determined in a separation apparatus by a sensor, which body is then seized laterally of the sensor by a first gripper and is vertically lifted, whereupon a further gripper engages under said body, laterally of the first gripper unit. The further gripper is then moved to the other end region of the body, with the body being lifted out of the bundle. Next, said body is moved to a deposition location by both grippers.

  • Patent number: 7625168
    Abstract: A combination pipe kicker/indexer for attachment to a pipe launcher is provided. The pipe kicker includes an articulated arm that is operated by a rotating shaft. The arm has a kicker head that rises up from a frame and moves towards a pipe located in the trough of the pipe launcher. Continued rotation of the shaft causes the kicker head to push the pipe out of the trough. Reversing the shaft rotation retracts the kicker arm into its frame. The indexer includes a plate having two eccentric cam openings and a cam rotatably mounted therein. Rotation of the cams causes either end of the indexer plate to rise up from the frame and urge a section of pipe towards the pipe launcher trough.

  • 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: 6485251
    Abstract: A lift system particularly designed for transport of pipes from a first to a second elevated location includes first and second storage locations with a lifter component positioned therebetween. The lifter is positioned such that pipes at a first location can be easily picked off a first location by the lifter for transport to the second location. Fingers on the drive chains of the lifter offer a two-point spaced contact to each pipe whether picked off the location or placed thereon by the user. Upon each pipe reaching the upper end of the lifter the fingers return to the lower end which causes a deposit of the pipe onto a second elevated location, e.g., a storage location, truck bed or the like.

  • Patent number: 6386823
    Abstract: A machine is disclosed for conveying wooden piece such as logs of wood and lumber, in wood transformation industries such as sawmills. The wooden pieces are conveyed in a conveying direction from the front towards the back of the frame of the machine. The machine has several conveying shafts rotatably mounted in parallel on the sides of the frame. Each shaft has a rotating axis about which it is driven in rotation in a direction corresponding to the conveying direction. Several toothed circular plates are mounted on each shaft and extend in a plane crossing the axis of rotation of the shafts. The plates of a shaft are designed to be offset with respect to the plates of an adjacent shaft. Each tooth of each plate are spaced apart from an adjacent tooth by a distance which corresponds substantially to the range of diameter of the wooden pieces and defines a space therebetween for receiving at least a portion of a wooden piece.
