摘要:
An apparatus and accompanying method for handling fabrics used in the construction of composite components and in particular those used in aircraft includes a movable, gantry-type frame assembly having a movable robotic arm attached thereto. A drum assembly, attached to the robotic arm has one or more vacuum ports disposed along the surface of the drum. When vacuum from within the drum is applied to the ports and the drum is moved to contact flexible fabric material—such as the reinforcement fabric used for composite manufacture—an end of the fabric may be picked up through the effect of the applied vacuum and the fabric rolled-up around the drum. The movable gantry and/or the robotic arm may then move the drum to a desired location where the fabric is unrolled and prepared for composite manufacture. Variations to the vacuum ports permit the rolling and transport of a variety of materials and shapes.

An apparatus and method for feeding single sheets of laminated thermographic print media are disclosed. The apparatus includes a traveling vacuum roller reciprocatable between pickup and discharge positions under suitable control so as to engage an end of the sheet near the pickup end and roll the sheet thereabout to a selected first angular position and then releasing the sheet end at such position. The vacuum roller continues to engage the sheet and applies a vacuum to engage the other end of the sheet so as to carry it to a second angular position and then releasing the sheet by releasing the vacuum as the roller approaches the discharge position. A wrapping roller engages the vacuum roller for directing the end of the rolled sheet towards the discharge after releasing it. A lift mechanism near the discharge position lifts the vacuum roller as it approaches the discharge.

An object of the present invention is to provide a vacuum suction control mechanism apparatus capable of accurately bonding a film to a bonding object with a simple structure. A vacuum suction control mechanism apparatus according to the present invention includes a first member including a plurality of suction holes formed in a surface thereof, the plurality of suction holes being connectable to a decompression source, and a second member capable of contacting the plurality of suction holes, the second member being movable relative to the first member, wherein the second member includes connecting member connecting some of the suction holes, the number of which corresponds to a relative position between the first member and the second member, to the decompression source.

An apparatus for the fault-free receiving and issue of sheets has guide rollers which are arranged on a carriage and which engage into belts to alter the geometry of the belts when the carriage is displaced on a rail over a stack by means of a drive. In the receiving or issue operation the sheet to be stacked or a top sheet to be issued rolls, without sliding, around one of the outer guide rollers, on the stack. Disposed between the outer guide rollers on a roller shaft are rotatable suction rollers whose suction cap sucks up the top sheet by means of reduced pressure at the beginnning of an issue cycle. A control arrangement is adapted to trigger off apparatus receiving and issue cycles and establishes predetermined positions of the carriage on the rail.

To take blanks of sheets for producing laminated glass, from a cutting table, an adjustable takeoff roller onto which the sheet blanks are wound is used. To fix the beginning of the sheet blank to be taken off to the takeoff roller, openings for applying negative pressure are provided in the lateral surface of the takeoff roller. When a sheet blank is taken from the cutting table, the takeoff roller is brought into position at the beginning of the sheet blank to be taken off, the blank is fixed to the takeoff roller and the takeoff roller is then moved along the cutting table while rotating about its own axis, and so the sheet blank is wound up around the lateral surface of the takeoff roller. For laying down the sheet blank onto a glass pane during the production of laminated glass, a correspondingly reversed procedure may be used.

Apparatus for delivering successive lowermost strip- or sheet-shaped commodities, such as labels, from a stack of commodities to a conveyor employs a rotary and reciprocable transfer member which pneumatically removes successive lowermost commodities from the stack, pneumatically attracts the commodities during transfer from the stack, and ceases to attract the commodities upon arrival at a station where the commodities are taken over by the pneumatically operated conveyor, such as an indexible or continuously driven rotary drum-shaped conveyor. The transfer member is reciprocated between the magazine and the conveyor by a reciprocable carriage which further serves to reciprocate a fluid flow regulating member acting as a valve to establish and interrupt the flow of air from one or more inlets of the transfer member to a suction generating device. The movements of various mobile constituents of the apparatus are synchronized, and such constituents can receive motion from a common prime mover.
