  • Patent number: 4669604
    Abstract: A vacuum single filer is provided for brining multiple rows of containers into single file at high speeds and over a relatively short distance. This is accomplished by discharging the containers in diagonal rows of three from a slotted dead plate onto a perforated conveyor belt extending over vacuum plenum chambers having slots therein for drawing a vacuum. The slot or slots aligned with the outermost container in each diagonal row draws sufficient vacuum to hold the outer container in fixed position and a deflector is used to direct the other containers into alignment behind the outer container and to slide them laterally across the belt as the belt moves them downstream until they are finally brought into single file alignment. An infeed vacuum conveyor cooperates with the slotted dead plate to arrange the containers in diagonal rows having a precise alignment prior to being picked up by the conveyor belt.

  • Patent number: 4653634
    Abstract: A conveyor belt assembly is provided with automatic tension adjustment. The assembly includes a conveyor belt trained about a pair of pulleys. A drive means powers one of the pulleys, each of which are mounted upon slidably interconnected frame members. A hydraulic cylinder in fluid communication with the motor and connected at opposite ends to each frame member automatically extends the first frame member with respect to the second frame member so as to increase the tension upon the conveyor belt as the load upon the belt increases. As the load upon the belt decreases, the fluid pressure within the motor and hydraulic cylinder decreases such that the first frame member is retracted with respect to the second frame member, thereby decreasing the tension upon the conveyor belt.

  • Patent number: 4650063
    Abstract: The present invention relates to an advancement device particularly adapted for use in a press for step-wise transport of material or of a workpiece; two gripper rails spaced from one another extend therein along a transport path. The gripper rails are reciprocally movable together along an advancement direction, while being movable in respective opposite directions along a direction transverse to the advancement direction. Two longitudinal guides receive the gripper rails, respectively, and a transverse drive drives the longitudinal guides in the respective opposite directions along the transverse direction. An advancement sled is reciprocally movable along the advancement direction, and an advancement drive drives the advancement sled reciprocally along the advancement direction. The gripper rails are connected to the advancement sled rigidly along the advancement direction, but are movably connected thereto along the transverse direction.

  • Patent number: 4635786
    Abstract: A conveyor passes across the exit end of a dryer through which strips of lasagna have passed carried on a succession of stick feeders. The conveyor is divided into a succession of narrow flights defined by upstanding push fingers. Mounted above the flight conveyor at the exit end of the dryer are a series of parallel tiltable shelves or flippers each having a width corresponding to a conveyor flight. Each of the stick feeders as it emerges from the dryer lays a group, for example, twenty-four U-shaped lasagna strips in parallel across the series of flippers. The stick feeder is then withdrawn through the open end of the U-shaped lasagna strip and the flippers are tilted to allow the lasagna strips to slide down into the conveyor flights. A friction belt moving at a speed faster than that of the conveyor assists in pulling the lasagna strips from the flippers and into the conveyor flights.

  • Patent number: 4633996
    Abstract: A belt conveyor frame including a supporting surface for an endless conveyor belt, a slot across the surface formed of two parallel faces and at an angle to the direction of proposed belt travel and over which the conveyor belt will move in opposite directions to two pulleys and disposed below and to the sides of the faces. The conveyor belt in passing over the faces, around the pulleys and then over the other face provides an angled discontinuity in the conveying surface of the belt. An interceptor device with diverter plates movably attached to an endless flexible member is mounted in the discontinuity so that the plates can be selectively raised to intercept and deflect an object passing on the conveyor.

  • Patent number: 4629055
    Abstract: Apparatus is described for arranging containers (1) e.g. bottles vertically, comprising an entry unit, sets of rod-shaped guides (23,24,25) helically shaped and symmetrical relative to the vertical longitudinal plane of the apparatus, and two belts (16) symmetrical and adjacent to such plane, which engage the initially uppermost side of the container. Operating in unison with and having the same speed as the lower branches of said two belts (16) are, firstly, the upper branch of an auxiliary belt (26), underneath said two belts (16), followed by inwardly facing branches of two subsidiary belts (31), symmetrical in relation to said plane and almost horizontal, so that the side of the container which is originally lowermost is continuously engaged by firstly the upper branch of the auxiliary belt (26) and then by the inwardly facing branch of one or the other of such subsidiary belts (31). This construction gives more reliable operation, especially at high speeds, then previously known apparatus.
