Abstract:
A sheet feeding apparatus includes a controller for shifting a sheet attractor from a stand-by state in which the attractor is away from a sheet accommodated in a sheet stacking device to an attraction state in which the attractor is elastically deformed to surface-contact with the sheet stacked on the stacker to electrostatically attract the sheet, to a separating state for separating the sheet from a lower sheet by lifting a downstream end of the sheet with respect to the feeding direction, and to a spaced state in which the attractor spaces the attracted sheet from the lower sheet, the controller changing a slackness of the attractor in the separating state on the basis of a stiffness information of the sheet.
Abstract:
The present invention relates to product dispensers, and in particular dispensers for products in the form of strips. The product dispenser includes a container having a lid that may be pivotally attached to a base. According to an embodiment, the assembly includes a cartridge housing and a dispensing cartridge. The dispensing cartridge is configured to house a stack of strips. A guide is biased by a spring to push a presser bar against the bottom portion of the stack of the strips toward the dispensing end of the assembly. When a strip is to be dispensed, a slider is moved from a first position to a second position, causing a slider arm to contact and assist in rotating a strip toward a dispensing opening. At least a corner of the rotated strip may protrude through the dispensing opening so that a user may remove the strip from the assembly.
Abstract:
The present subject matter relates to methods and systems for feeding sheets or batches of sheets, where a sheet feeder tray capacity level of a sheet feeder table is controllably varied through a hardware or software user interface, allowing a user to selectively set the sheet feeder table capacity level to any desired level according to a user's needs, and resulting in reduced overall batch feeding time and increased productivity as a result of less feeder tray movement during the feeding process. Control of the feeder tray capacity level through a user hardware interface is achieved by using "up" and "down" buttons or other keys on a control panel to adjust the feeder tray capacity level setting. A control panel button can also provide an automatic capacity setting feature. Control of the feeder tray capacity level through a user software interface is achieved by entering the desired feeder tray capacity.
Abstract:
Die Erfindung betrifft eine Vorrichtung zum Zuführen von flachen Gegenständen zu einer Reib-Saug-Vereinzelungseinrichtung mit einer Saugwanne (2), die stapelweise auf einer Schmalseite stehend, von einer Anlagefläche unterstützt sowie an einer Anschlagfläche (6) ausgerichtet durch ein sich zur Abzugsstelle bewegendes Fördermittel (5) transportiert werden. In oder an der Saugwanne (2) ist ein den Unterdruck in der Saugwanne (2) messender Sensor (7) angeordnet, der an eine Antriebssteuerung des Fördermittels (5) angeschlossen ist. In Abhängigkeit vom gemessenen Unterdruck ist das Fördermittel (5) so ansteuerbar, dass der vorderste Gegenstand an dem mindestens einen Reib-Abzugsmittel (1) eine möglichst geringe Schräglage bei möglichst geringem Stapeldruck aufweist.
Abstract:
A film supply system (34) for use within a photosensitive film imager (30). The film supply system (34) includes a cartridge (48) receiving apparatus and a film pick-up mechanism (50). The cartridge receiving apparatus (48) includes a tray (60), a guide frame (62) and an elevator mechanism (68). The guide frame (62) is configured to be disposed within an imager housing (32). The tray (60) includes a floor (70) and extending walls (72) for maintaining a film cartridge (44) and is pivotably received by the guide frame (62). The tray (60) further defines a cartridge insertion passage and moves between and elevated position and a retracted position relative to the guide frame (62). In the elevated position, the cartridge insertion passage is normal to a film travel path of the imager (30). Finally, the elevator mechanism (68) is disposed within the imager housing (32) and drives the tray (60) between the elevated position and the retracted position. The film pick-up mechanism (50) includes a retention frame (222), a drive frame (226), a drive means (224), a heel plate (228), and a cup plate (230). The retention frame (222) is configured for selective attachment within the imager housing (32) and slidably receives the drive frame (226). The drive frame (226) is driven by the drive means (224) between an extended position and a retracted position and is attached to the heel plate (228) opposite the retention frame (222). The cup plate (230) includes a suction cup (342) and is pivotably attached to the heel plate (228). During use, the drive means (224) directs the drive frame (226), the heel plate (228) and the cup plate (230) to retrieve, separate and deliver sheets of film to a film transport system (42).
Abstract:
Described is a device (1) for manipulating sheets for a mattress packaging machine (100) comprising at least one supporting device (2, 2a) designed to receive a stack (3) of sheets (4) designed to make a mattress. The supporting device is movable to position a first sheet (4a) at a predetermined and constant gripping position (5), thus forming a sheet being processed (4b). A conveyor (7) is designed to receive the sheet being processed (4b) and to convey it inside the packaging machine (100) at a packaging path selected from a plurality of packaging paths (P1, P2) positioned at different heights. A conveyor (7) is movable between a transfer position (8) wherein it receives the sheet being processed and a plurality of conveying positions (9a, 9b) each positioned at a packaging path. The transfer position (8) is positioned at a height greater than that of the conveying positions (9a, 9b). A transport platform (10) is movable between the gripping position (5) and the transfer position (8) to pick up the sheet being processed (4b) and to make it available for the conveyor (7).
