Abstract
Apparatus for collecting, counting, stacking, turning over and arranging bags or sacks produced in a high production bag manufacturing machine for assembling and wrapping in desired bundles of uniform dimension for shipment or storage. The apparatus is synchronized with the bag machine to automatically accept the output therefrom for collecting in discrete stacks of a given quantity which are then overturned and fed by a conveyor into a wrapping apparatus with the bottoms of the bags of adjacent stacks positioned at opposite ends for assembling and wrapping in bundles of a uniform thickness to accommodate storage and shipment of the wrapped bundles.
Claims21
An automatic bag stacking and collating apparatus for use with a high capacity bag manufacturing machine, which is powered by a suitable drive means and which bag machine produces bags with closed bottom ends said apparatus comprising:
- a frame having a receiving end portion, a transfer surface, and an unloading end portion,
- a plurality of bag handling functional devices including:
- a receiving means positioned adjacent to said bag machine and arranged to receive flattened bags from said bag machine,
- a collection means carried on said frame at said receiving end portion and arranged to separate predetermined quantities of bags received from said receiving means into groups and to periodically deposit
- a collected group on said transfer surface in a flat orientation with side edges of said bags aligned to form a vertically aligned stack,
- a pair of laterally spaced turnover devices positioned downstream and laterally outward of said collection means for overturning said vertically aligned stacks of bags, a transfer swing means movable along said transfer surface to load said flat oriented and vertically aligned stacks of bags deposited on said transfer surface into the pair of turnover devices in an alternating sequence with said bag closed bottom ends positioned in opposing orientation relative to one another,
- a conveyor means positioned between said pair of turnover devices and arranged to advance said overturned stacks of bags to said unloading end portion in spaced aligned orientation,
- means to transfer said overturned stacks of bags alternately from said pair of turnover devices and onto said conveyor means,
- means for transferring said stacks of bags from said conveyor means and into a wrapping machine,
- a drive arrangement for said bag stacking and collating apparatus arranged to synchronously drive each of the plurality of bag handling functional devices whereby individual bags are received from the bag machine and are automatically collected in stacks of a given quantity, said stacks are repositioned to place their closed bottom ends in opposing orientation relative to one another and are overturned and arranged in an aligned and spaced orientation for conveying down stream for assembling a plurality of stacks into bundles of a generally uniform thickness to facilitate wrapping and storage.
An apparatus for automatically stacking and collating flattened bags with folded-over closed bottom ends as produced by a bag manufacturing machine, for arranging in stacks and assembling a plurality of stacks in bundles of generally uniform thickness comprising:
- a collection means arranged to continuously receive individual flattened bags from said bag manufacturing machine and separate given quantities of bags into stacks,
- means to periodically deposit individual stacks of bags onto a transfer surface in a flat orientation with side edges of said bags being vertically aligned,
- means to sequentially reposition said stacks of bags from a position as deposited on the transfer surface while moving said stacks along said transfer surface comprising a swing frame having pusher arm means being operable to reposition said stacks of bags with said closed bottom ends in each stack being in opposed orientation to the closed bottom ends of alternately repositioned stacks of bags,
- a turnover means adapted to receive said stacks of bags with closed bottom ends of successive repositioned stacks of bags in opposing orientation and sequentially overturning successive repositioned stacks of bags, a conveyor means arranged to receive repositioned and overturned stacks of bags for conveying therealong in a spaced and aligned orientation, and
- a transfer means arranged to move said repositioned and overturned stacks of bags sequentially onto said conveyor means, whereby a given number of repositioned and overturned bags are advanced to an apparatus for assembly into bundles of a generally uniform thickness to accommodate wrapping and storage.
