Method and device for the generation and/or conveyance of a shingled stream of flat, flexible objects

摘要

A device for the generation of a shingled stream of flat, flexible objects along a conveyor path, wherein successive objects develop an overlap with a length, includes a first and a second suction and conveyor device having a first and second unit, respectively, and each having at least one conveyor belt. The first and second units are each configured to generate a vacuum through a whirlwind to attract at least one of the objects and are each disposed in a casing having a suction aperture. The second suction and conveyor device is disposed downstream from the first suction and conveyor device in a direction of the conveyor path with a mutual offset corresponding to the length of the overlap and is disposed at an angle relative to the direction of the conveyor path. The first and second suction are separated by a spacing in a transversal direction.

主权项

1. A device for conveying a shingled stream of flat, flexible objects along a conveyor path, wherein successive objects have an overlap with a length, the device comprising:
at least three first suction and conveyor devices disposed along the conveyor path successively in a direction of the conveyor path, each of the suction and conveyor devices including a first unit and at least one conveyor belt, the first units each being configured to generate a vacuum through a whirlwind to attract at least one of the objects and being disposed in a casing having a suction aperture, wherein velocities of the conveyor belts in each of the first suction and conveyor devices are controllable individually and independently from one another, wherein the at least three first suction and conveyor devices are disposed downstream, in the direction of the conveyor path, from a device for generating the shingled stream of flat, flexible objects, the device for generating comprising:
a second suction and conveyor device including a second unit and at least one conveyor belt, the second unit being configured to generate a vacuum through a whirlwind to attract at least one of the objects and being disposed in a casing having a suction aperture; anda third suction and conveyor device disposed downstream from the second suction and conveyor device in the direction of the conveyor path with a mutual offset corresponding to the length of the overlap, the third suction and conveyor device being disposed at an angle relative to the direction of the conveyor path, the third suction and conveyor device including a third unit and at least one conveyor belt, the third unit being configured to generate a vacuum through a whirlwind to attract at least one of the objects and being disposed in a casing having a suction aperture,wherein the second and third suction and conveyor devices are disposed on different sides of the conveyor path, respectively above and below the flat, flexible objects, and separated by a spacing in a transversal direction of the conveyor path.
