  • Patent number: 6579053
    Abstract: A robotic containerization and palletizing system having a multiple-fingered end effector. The system includes a frame that defines one or more cells. Each cell has one gantry-type robot, which is mounted in a set of tracks on top of the frame. The robot is movable along two axes and has an arm to which the end effector is mounted. The end effector is designed to grasp trays, tubs, and similar items from a conveyor system running through the cell and load them in a cart or on a pallet. The items are gripped by two sets of fingers. One set of fingers may be mounted to a first plate and another set of fingers may be mounted to a carriage that moves in a horizontal direction, either toward or away from the first set of fingers. Each finger has a main shaft and a bent tip. The shafts are rotatable such that the tips can be moved underneath or out from under a load, depending upon whether a pick-up or drop-off operation is being performed.

  • Patent number: 6572101
    Abstract: A jogger for a signature feeder includes a back stop disposed at a first side of a hopper of the feeder and a flexible jogging element disposed at a second side of the hopper opposite the first side. As a stack of signatures is formed in the hopper, the flexible jogging element is oscillated in a lateral direction so as to periodically bend the flexible jogging element against the stack of the signatures and form a pushing zone and a vibrating zone in the hopper. The vibrating zone is below the pushing zone, and the vertical lengths of the pushing and vibrating zones are a function of the height of the stack of signatures. The signatures in the pushing zone are urged against the back stop by the flexible jogging element so as to register the signatures as the stack is formed, and the signatures in the vibrating zone are vibrated by the flexible jogging element so as to improve the registration of the signatures in the stack.

  • Patent number: 6565308
    Abstract: A Bulk Mail Container (BMC) unloader uses a simple crossed four bar-linkage to move a predetermined point on a BMC unloader in a substantially straight line while the overall BMC unloader rotates about that predetermined point so as to upend the BMC container. This takes advantage of the crossed four-bar's substantially straight-line motion over a limited range of its motion, as well as the rotational motion of the particular unloader link disclosed herein. This is advantageous for unloading. In use, a BMC container is simply rolled into the BMC unloader, and the entire combination of the BMC container and BMC unloader is then actuated to produce substantially straight line motion along a suitably selected “center” point of the BMC unloader while the overall combination rotates about the center point so as to upend the BMC for unloading.

  • Patent number: 6537017
    Abstract: A pallet positioner includes a support frame that consists of a main upright structure with a pair of spaced, parallel outriggers extending horizontally at ground level. The distal ends of the outriggers are connected by a flat, low-profile ramp. The upright structure includes a pair of vertical guide masts rigidly mounted on a horizontal base bracing the proximal ends of the outriggers. A cantilevered carrier with a rotatable platform is mounted laterally for vertical motion along the vertical guide masts. A pneumatic bellows and an air reservoir in the base are adapted to raise and provide self-leveling to the platform. Two hydraulic cylinders provide dampening and a stabilizing effect. The flow of hydraulic fluid in the cylinders is used to control the motion of the carrier. A braking system under the platform prevents its rotation at ground level.
