摘要:
A sheet separator machine for cartons for packaging from a warehouse, typically a well warehouse, in which the cartons are stacked. More particularly, a machine for separating sheets of cartons. The machine includes a frame on which a handling station of the cartons, a warehouse for at least one stack of cartons, and a gripping station of the cartons, are mounted, in an operatively contiguous position. The gripping station includes a pair of counter-rotating motorized rolls for withdrawing a carton from the stack of cartons.

The enclosure feed device is constituted in such a way that a drive motor is provided for rockably driving a rocking arm, and a control unit is provided for causing the memory section to input the variable amount relative to the sucking position of the sucking cap in conformity with the thickness of said enclosures from the variable amount inputting section and storing the same and adjusting the sucking position of said sucking cap by controllably energizing the drive motor for sucking operation in accordance with the variable amount stored in the memory by means of the CPU section.

According to the invention, separator plates bevelled at the front edges provided on the rotating feed segments of a sheet feeder, more particularly for envelope machines, which finally separate from the pile of blanks a blank for feeding, the front edge of the bottom flap of the blank having been separated from the pile by means of a tongue and vacuum device. The separator plates align the blank in the direction of conveyance, smooth it out, and then feed it to the extractor roller and engagement edge of the rotating feed segments.

In a modified embodiment of the pull-foot sheet feeding device described in U.S. application Ser. No. 608,970, filed Aug. 29, 1975, now Pat. No. 4,013,283 the bottom roller is replaced by a roller segment. The roller segment is pivotally mounted on a carrier which is fixedly mounted on a driving shaft. The pivotal axis of the roller segment is offset from the axis of the driving shaft. The roller segment has an outer surface for pinching sheets between it and the pull-foot while rolling on a sheet in response to rotation of the driving shaft. The position of the roller segment relative to the carrier is constrained by a spring, which provides biasing of the roller segment surface against the pull-foot, and an adjustable stop. The pull-foot is driven outwardly to pull sheets from a hopper by the roller segment but is under the control of a biasing spring and cam during its return.

In a mechanism for feeding individual sheets of paper separately from a stack of paper sheets, a separating device exposes an edge of an outer sheet and a "pull-foot" is oscillated between the separated sheet and a remaining stack. A roller is concurrently moved into position to pinch the separated sheet between the pull-foot and the roller. The pull-foot is oscillated away from the stack and, in doing so, the outer sheet is pulled from the stack by interaction between the pull-foot and the roller.

Pneumatic means are synchronously coupled to an offset machine or the like in order to positively separate and pull down the bottom sheet in a stack. Movement of the pneumatic means is synchronized with the movement of a pivotal roller that advances the pulled-down sheet onto a conveyor belt for delivery of the sheet to the utilization device. The sheet being fed is automatically aligned in a lateral direction by movable guide means that are synchronized with the feeding of the sheet. The forward edges of the lower most sheets on the stack are separated by a flow of air.
