摘要:
Arrangements for feeding out sheets to stacking magazines in general feed out sheets one at a time at the upper end of the magazine, where they fall freely downwards and together form a stack. The comparatively low rate of fall of the sheets limits the working speed, and in order to increase the working speed and functional reliability an arrangement is proposed in accordance with the invention, wherein the sheets (6) are fed out from a carriage (2) which is lifted in timed relation with the growth of the stack of sheets so that the sheets are fed out the whole time directly to the top end of the stack.

Provided is a document conveying apparatus that properly discharges documents regardless of the amount of documents stacked on a discharge tray without complicated construction of a transmission mechanism for transmitting a driving force to conveying rollers. A conveying roller pair (97) is provided at an end portion on an upstream side. A swing mechanism (37) swings a discharge mechanism (36) centered around a drive shaft of the conveying roller pair. An upper surface height measuring unit (19) measures the height of the upper surface of documents stacked on the discharge tray (43). A control unit (10), by causing the swing mechanism to swing the discharge mechanism according to the height measured by the upper surface height measuring unit, performs control so that the difference between a discharge port (70) and the upper surface of the documents stacked on the discharge tray is within a specified range.

One embodiment of the present disclosure relates to a stacking device including a conveyor belt (105) configured to move one or more items towards a receiving storage hopper (125) configured to receive the one or more items from the conveyor belt. The one or more items may form a stack (124) of items in the receiving storage hopper. The stacking device may further include a sensing device (117) configured to determine a level of the stack of items in the receiving storage hopper. The stacking device may be configured to adjust a height of the conveyor belt relative to the storage hopper based on the level of the stack of items in the receiving storage hopper.

A method for feeding a shingled stack (SS) of sheet material (12) to a downstream processing device (30) includes the step of identifying a discontinuity (PG) in the shingled stack of sheet material wherein the discontinuity has a length dimension from an aft end of a downstream portion (SS1) of the shingled sheet material to a forward end of an upstream portion (SS2) of the shingled sheet material. In a next step, the motion of first and second serially arranged conveyors (50, 40) are controlled such that the length dimension of the discontinuity is substantially equal to a prescribed gap (PG) of known length dimension. The first conveyor (50) supports the upstream portion (SS2) of the shingled sheet material and the second conveyor (40) supports the downstream portion (SS1) of the shingled sheet material. The deck of the first (50) is advanced over the deck of the second conveyor (40) toward the aft end of the downstream portion by the length dimension of the prescribed gap (PG). The upstream portion is then dispensed into shingled engagement with the downstream portion to produce a continuous stack of shingled sheet material.
摘要:
A product grouping station (1), of the type that comprises a product pickup and conveyance member (2), a unit (3) for forming groups of products and a compaction apparatus (4). The station (1) comprises at least one movable carriage (5), which is arranged downstream of the pickup and conveyance member (2), for insertion in at least one compartment (6) of the products to be grouped, a pusher (7) for transferring the groups of products in the compaction apparatus (4). The compaction apparatus (4) comprises at least one lateral face (8) that can perform a translational motion from a maximum distance with respect to the face (9) that lies opposite thereto to a minimum distance, in order to reduce the overall bulk of the group.
摘要:
A machine for stacking sheets into bundles comprises: a stacking area; at least one overhead conveyor (50) arranged above said stacking area; suction means for drawing successive sheets into contact with an underside of said at least one overhead conveyor (50); and means for disengaging said sheets from said at least one overhead conveyor (50) wherein in use successive sheets are drawn into contact with said underside of said at least one overhead conveyor (50) and conveyed to a predetermined stacking position whereupon said sheets are disengaged from said at least one overhead conveyor (50) and fall to form a bundle of stacked sheets in said stacking area. There is also provided a machine for stacking sheets into a plurality separate stacks comprising: (a) conveyor means for successively conveying individual sheets into a stacking area; (b) first and second sets of support fingers extending horizontally in said stacking area; (c) said support fingers having lengths sufficient to support the entire weight of said stacks; (d) means for moving said first set of support fingers horizontally between a retracted position and an extended stacking position; (e) means for moving said second set of support fingers horizontally between a retracted position and an extended stacking position; (f) means for moving said first set of support fingers vertically; and (g) means for moving said second set of support fingers vertically so as to sequentially support the full weight of said stacks on said first and second sets of support fingers.
