  • Patent number: 5564894
    Abstract: A partition inserter has a vacuum assembly which pivots out to contact an end partition in a stack, pivots back to remove the partition, and then moves downwardly to release the partition. The positioning of the vacuum assembly is controlled by a set of cams and a cam follower for controlling the horizontal position of the vacuum assembly and a third cam and cam follower for controlling the vertical position of the vacuum assembly. The vacuum assembly has an upper set of cups which move down with the assembly to lower the partition. The upper vacuum cups are also adjustably mounted to the assembly so that the same assembly may be used for partitions of various sizes. When the partition is released from the vacuum cups, the partition is guided downwardly by a pair of conveyors to a set of shooter wheels. The conveyor and shooter wheels are mounted to a set of plates which are adjustably mounted to the frame of the apparatus.

    Abstract: Stacks of fabric plies are sequentially positioned by a carousel feeding apparatus in an unloading position where the uppermost ply in a stack, so positioned, is individually and sequentially separated from the stack, and an edge thereof presented between the jaws of a gripping device. Once the gripping device is satisfied that one and only one fabric ply is in place between the jaws, the single ply is transferred over onto the receiving end of a conveyor for further processing. The fabric separation occurs by means of an aerodynamic technique which tends to lift by suction the uppermost ply from the remainder of the stack. A proximity switch determines the spacing between the gripper jaws which spacing confirms the existence of one and only one fabric ply therein.

  • Patent number: 4637599
    Abstract: The invention is concerned with a suction-lifting conveyor for the transfer of sheet-shaped objects, in particular of sheets of plywood veneer (4), one by one from a stack to further processing or to another stack. The device comprises a box-shaped suction-channel equipment (1) extending substantially over the entire length and width of the conveyor, blower means (2) for maintaining a negative pressure in the suction-channel system, endless belts (3) performing the transfer of the sheets and running substantially horizontally above the stacks of sheets, the said belts being arranged so that during their transfer movement they run against the outside of the bottom face of the suction-channel system, being subject to the effect of the negative pressure in the suction-channel system, and that during their return movement they run in the suction-channel system.

  • Patent number: 4621798
    Abstract: In a high speed mail sorting machine, a mechanism for feeding envelopes one at a time to a pickoff device such as a vacuum belt system. The envelopes are loaded onto a floor panel which inclines from side to side. A chain conveyor moves the envelope supply along the floor panel with each envelope having its lower edge traveling on the floor and one side edge travelling along an inclined side panel. The envelopes are successively discharged from the inclined floor onto a conveyor belt which is driven transversely to the floor and at a greater speed than the chain conveyor. The speed difference causes the envelopes to spread out as they travel downstream. The conveyor belt loads the envelopes onto a driven roller having a spiral groove which feeds the individual envelopes flatly against the vacuum belts of the envelope pickoff device.

  • Patent number: 4588180
    Abstract: A loader for box-type feeders of packaging machines, bookbinding machines and the like, in which the products are loaded into a feed channel with an inclined base formed by a conveyor belt, to be brought into contact with a counteracting plate. Sucker arms cyclically withdraw one product at a time and transfer it to wheels provided with grippers which insert the product between pairs of belts by means of which the product is transferred until it discharges into the feeder box. Feeler elements cyclically determine the thrust of the products in the feed channel and enable the conveyor belt to advance through one step when the thrust is smaller than a predetermined value, whereas they prevent said advancement when the thrust is greater than said value.

  • Patent number: 4580770
    Abstract: Sheets are fed from the top of a stack (12) by a continuously rotating vacuum wheel (40). After the leading edge of a just-fed sheet is detected, a control circuit (110) de-energizes valve means (92) whereby the wheel (40) is effectively disconnected from a source of vacuum (90). Indicia borne on the just-fed sheet is read using a probe (23). If the indicia indicates that the just-fed sheet is related for grouping purposes to previously-fed sheets, the control circuit (110) energizes valve means (92) whereby vacuum is applied to the wheel (40) for the feeding of a further sheet. If the indicia indicates that the just-fed, just-read sheet is not related to previously-fed sheets, the control circuit (110) does not energize the valve means (92) for the feeding of a further sheet until the control circuit (110) receives an indication that all previously-fed sheets have been grouped and discharged onto an insert track (32).

  • Patent number: 4491311
    Abstract: Apparatus for opening up folded sheets has a rotary withdrawing conveyor which extracts successive folded sheets from a stack and places successive withdrawn sheets into a path between two rotary spreading elements in such a way that the front edges of the sheet in the path are adjacent to the respective spreading elements and the back of the sheet is located at a level above the front edges. The spreading elements are driven in opposite directions and carry jaws which engage the respective front edges of a sheet therebetween in first angular positions of the spreading elements, whereupon the jaws move the sheet downwardly to move its front edges apart and to separate it from the withdrawing conveyor, and ultimately release the sheet in second angular positions of the spreading elements so that the sheet can descend onto a removing conveyor.
