  • Patent number: 4972937
    Abstract: Apparatus for transporting articles includes a closed track having rectilinear track portions. Disposed in the track are a plurality of series of carriers movable along the track and arranged to carry the articles. A drive is provided which acts on the respective rear one of a series of successive carriers, which contact each other in a non-resilient manner, for incrementally moving the carriers along the track. There is also provided a joining device which acts on the carriers of a series to keep the carriers in closed-up formation as they are moved.

  • Patent number: 4892181
    Abstract: A method of and a device for aligning products like slabs and bars of chocolate or pastries on a conveyor belt by a retainer rod. The retainer rod descends from a raised position to between two adjacent rows of confections, travels along with the conveyor belt but at a lower speed, and, once the rows of confections have been aligned, accelerates, rises, and returns to its initial position.

  • Patent number: 4848533
    Abstract: A conveying apparatus for panels is equipped with two revolving endless conveyor belt members such as chains etc. The chains are connected with each other with successively arranged transverse organs such as cross bars. On each cross bar there are mounted displaceably with braking two panel-engaging devices comprising clamping springs for gripping and transferring panels from a charging to a discharging station past a random number of intermediate processing stations. Two pneumatically operable pusher members push the panel-engaging devices into contact with the lateral edges of an arriving panel and cause the clamping springs to grip the panel. At the discharging station, two separating pusher members of similar construction open the clamping springs and push the panel-engaging devices apart toward their terminal positions at opposite ends of their cross bar, thus setting the panel free to be discharged from the apparatus.

  • Patent number: 4693362
    Abstract: A chain conveyor for the delivery device of printing presses has gripper systems (1) being carrier directly by the endless conveying chains (2). The gripper system (1) is embodied by a unitary aluminum basic member (6). A steel tube (9) is cast into the basic member (6) at its center of gravity and over its whole length and optimizes the flexural and torsional rigidity of the gripper system (1).

  • Patent number: 4637775
    Abstract: An industrial robot device is disclosed which is equipped at a forward end of an arm with a work tool such as a cutting or a grinding tool, and in which there is provided a device such as a friction damper for suppressing sudden movement of the work tool in the direction of the normal displacement thereof towards and away from a workpiece. Damage to the work tool and workpiece due, for instance, to sudden changes of load, is thereby prevented.

  • Patent number: 4417653
    Abstract: A pusher conveyor has a series of retractable pushers pivotally connected to an endless chain. The pushers are provided with guide pins which run in guide tracks parallel to the conveyor path. Switches are provided between the guide tracks to guide the pins from one track to another to thereby extend or retract the pushers to engage or disengage articles along the conveyor path. The switches can be coupled to sensors, to enable articles to be stacked along the conveyor path.

  • Patent number: 4236708
    Abstract: Apparatus for feeding individual cardboard sheets to a rotary die cutting machine has two conveyor systems. The first system conveys a sheet from the bottom of a stack to a gap in a gate which passes only one sheet, and the second system conveys the sheet from the gap to the machine. Each system includes a perforated belt traveling in a closed loop over a suction box near the gate. The belt of the first system is shifted cyclically between an operative position of simultaneous engagement with the associated suction box and the bottom sheet of the stack and a retracted position and is accelerated and decelerated between a minimum speed in the retracted position and a maximum speed in the operative position, air being drawn from its suction box only in the operative belt position. The belt of the second system is driven continuously at a speed approximately equal to the maximum speed of the other belt, and air is drawn from its suction box only when the first belt is in the retracted position.
