    Abstract: A destacker for automatically destacking a plurality of vertically stacked articles that is particularly useful in destacking magnetic moulds used in the chocolate manufacturing industry. Each article comprises at least one slanted notch. The destacker includes at least one hammer having a blade that moves from a retracted position to an extracted position, wherein at the extracted position the blade engages a gap formed by the slanted notch between the bottommost article and the article located above the bottommost article to release the bottommost article from the plurality of stacked articles. The bottommost article then drops onto a conveyor to be transported to the production line. The destacker further includes oppositely disposed pair of mould carriers and oppositely disposed pair of mould lockers that assist the destacker to feed the stack of moulds in a downward direction.

  • 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.

    Abstract: Book bindery and trimming apparatus which is directly connectable to the output of a digital printer enable substantially automatic book production. Individual sheets are cut from a printed web, folded and driven into a sheet stacker. The stacker collects the sheets onto a pair of vanes mounted on respective drums until the end of a book is reached. At this point the stacker is moved to its next position(s) and the sheets forming the collected book are deposited on a stack collector. Meanwhile, a new pair of vanes present themselves for book collection. The collected book progresses through a stitcher, for wire stitching, and then to the trimming apparatus. The trimming apparatus has a book path inclined downwardly towards a backstop which, in cooperation with front stop fingers, ensures reliable alignment of the book for trimming.

  • Patent number: 4821919
    Abstract: Apparatus for stacking conical objects includes right hand and left hand side walls which are joined by divergent walls to define a tapering horizontal cross-section column in which the spacing between the opposite walls is shorter than the length of any one of the conical objects. The conical objects can be placed manually in the top of the column 1 but only in a given orientation (thanks to the tapering horizontal cross-section of the column) and only when hooked on a retaining finger projecting into the column through the side wall. The conical object at the top of the stack thus settles into an inclined orientation which it retains when the retaining finger is released to drop the cone down the column, thanks to an inertia brake to retard the wider diameter end of the falling cone and preventing the cone from becoming vertical. The retaining finger at the foot of the column releases only the bottom cone and allows any cones above it to become indexed downwardly into the bottom-most position.
