DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a device for charging an insetting machine with printed products, the insetting machine having successive pockets that are sequentially moved along a conveyor path in a conveying direction. Inset products are charged with a given edge first into the pockets.
Known insetting machines are charged by sheet feeders that are disposed above the conveyor path of the successively-following, pocket-like receiving elements and have a conveyor or a stacking hopper.
In the latter case, because of their position above the conveyor path, which is disadvantageous with respect to operation, the sheet feeders are charged manually from a platform raised from the floor. This work requires great physical effort and involves risks of accidents, as well as relatively long access paths to the sheet feeders.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to create a device for charging an insetting machine with printed products that permits the insetting machine to be allocated a corresponding sheet feeder that can be operated ergonomically.
This object is attained in accordance with the invention by an arrangement comprising a sheet feeder disposed to convey the inset products approximately perpendicular to the conveying direction of the insetting machine. A conveyor segment is disposed downstream of the sheet feeder and ending above the conveyor path of the insetting machine for conveying the inset products from the sheet feeder to the pockets of the insetting machine. The conveyor segment is formed by two endless flat belts having respective conveying surfaces that are adjacent to one another for grasping the inset products therebetween. Additionally, deflector rollers for circulating the flat belts are provided. The printed products can thereby be conveyed to the pockets in a simple and less tiring procedural manner. The sheet feeder stack can also be charged by a conveyor or a different conveyor element, for example conveyor belts.
Transport of the printed products so that they need not be turned on the way from a sheet feeder mounted at a side of the conveyor path of the insetting machine to the pockets of the insetting machine is problematic, because, due to the printed products, insufficient stability, the printed products would have to be clamped at at least two distanced locations on the flat belts to prevent deformation.
The flat belts of the device of the invention are preferably guided over an axis of a reversing roller seated above the path and disposed approximately parallel to the conveying direction of the insetting machine; afterwards, the flat belts form an approximately vertical, downwardly-oriented guide gap through which the surfaces or formed run of the flat belts are rotated together by approximately 90.degree.. The flat belts are acting as conveyors. This structural measure permits a simple and effective configuration of the conveyor segment.
A device in accordance with the invention, having a sheet feeder that is principally known per se and is essentially formed by a stacking hopper and a downstream gripper drum, proves advantageous when the flat belts form an undershot conveyor segment with the gripper drum.
It is provided in this case that the flat belts are disposed approximately central with respect to the drum width and have approximately its turning radius.
The end of the conveyor segment in the conveying direction is advantageously configured as a feed opening formed by the flat belts and communicating with an output end of the stacking hopper. The feed opening permits a friction-free transfer of a printed product from the sheet feeder to the conveyor segment.
It is thus possible to arrange the folded edge of the printed products located in the stacking hopper to face away from the pockets of the insetting machine.
Alternatively, in a device in accordance with the invention, a sheet feeder known per se and essentially comprising a stacking hopper and a downstream gripping drum is disposed upstream of the conveyor path.
