  • Patent number: 8534985
    Abstract: A feeding device includes a support mechanism, a movable platform, a driving mechanism, a clutching mechanism, and two or more holding mechanisms. The movable platform is movably connected to the support mechanism, and loads feed trays stacked together. The driving mechanism drives the movable platform to move relative to the support mechanism. The holding mechanisms are fixed on the support mechanism, and switch from a first position to a second position. When the holding mechanisms are positioned in the first position, the holding mechanisms grasp one feed tray adjacent to a feed tray at a top of the feed trays, and the clutching mechanism clutches the feed tray at the top of the feed trays. When the holding mechanisms are positioned in the second position, the holding mechanisms separate from the feed trays.

  • Publication number: 20120207578
    Abstract: A card dispensing system for dispensing cards along a conveying surface which conveys sliced products downstream of a slicer for packaging the sliced products. A hopper contains a stack of cards which are withdrawn from the hopper by a suction force provided via at least one suction cup. The suction cup is moveable vertically to retrieve and remove the card from the hopper. The suction cup is moveable laterally to move the card into a receiving position where a card clamp on a damp carriage arrives to receive the card. Suction force on the card is released when the card damp damps down on the card. The clamp carriage moves the card from the receiving position to the staging position where a nip engages with the card to feed the card through a junction in the conveyor line just as a food product passes over the junction.

    Abstract: A device for loading, storing and providing objects having standardized dimensions includes a storage unit with a carrier plate and four stackers. Each stacker includes a bottom surface disposed on top of the carrier plate. The stackers are configured to store objects stacked perpendicular to the carrier plate. The stackers are disposed symmetrically centered around a rotation axis that is perpendicular to the carrier plate and offset with respect to each other by an angle of 90°. A substructure is disposed underneath the carrier plate. An unloading device is configured to unload a selected object from a first of the stackers that is disposed in a transfer position. The storage unit is rotatable around the rotation axis so as to enable movement of each of the stackers into the transfer position.

  • Publication number: 20110036757
    Abstract: Provided are an apparatus for feeding sheets, booklets or the like having a wider adjustable range according to the thickness of the object than the conventional apparatus, and a system for sorting forwarding documents with the foregoing feeding apparatus. In the feeding apparatus, a moving shaft is supported by a fixed sleeve so as to be movable upward and downward. A main compression coil spring is located between the moving shaft and the fixed base and imparts a main spring force to the moving shaft in order that an overlap feed limiting member is pressed against a conveying belt. A sub compression coil spring imparts an oppositely directed sub spring force to the moving shaft. A position of a pressing washer is displaced downward by a threading engagement of an upper end adjusting bolt, so that even when the spring force of the main compression coil spring is increased, an increased amount is cancelled by an increase in the spring force of the sub compression coil spring.
