  • Publication number: 20030017043
    Abstract: For stacking flat articles (2), a stacking shaft (10) comprising pushing means (11) for removing stacks from the shaft is used and for supplying the articles (2) into the stacking shaft (10) a supply support (12) is used. The supply support (12) is oriented towards the opening of the stacking shaft (10) at in inclination from above and the completed stacks (1) are pushed out in a direction opposite the supply direction. This makes it possible to resume the supply operation after an interruption necessary for the pushing-out, before the stack (1) is pushed out of the stacking shaft (10) completely. This results in very short cycle times. The stacking method is suitable in particular for stacking folded printed products being supplied in the supply stream parallel to their folded edges. The device is distinguished by its simplicity and by the fact, that it requires very little space.

  • Publication number: 20030015837
    Abstract: A conveying-in stream, in which flat articles (4) are conveyed held gripped individually, is transformed into a conveying-away stream, in which the articles (4) are loosely lying overlapping one another in an imbricated manner and in alternating groups oriented rotated relative to each other. The transformation is implemented, in that the conveying-in track intersects with the conveying away track at two track intersections (A and B) and in that the articles (4) are transferred from the conveying-in track to the conveying-away track in alternating groups (1A, 1B, 2A, 2B . . . ) at the first track intersection (A) or at the second track intersection (B). In the conveying-away stream, the articles (4) are arranged in imbricated stream sections (1A/1B) each section comprising one or two groups (1A, 1B, 2A, 2B . . . ) of articles (4) and being separated from neighboring sections by a stream gap (22).

  • Patent number: 6464067
    Abstract: The invention relates to a method and device for buffering with the use of a closed gripper. The invention comprises transport means (20) which are provided with grippers (22), can move along a conveying section (10), and are located in the area of a buffer section (14) of the conveying section (10). Transport means are stored in such a way that the distance between the transporting means (20), said means being successively arranged in the buffer section (14), is essentially determined by the degree of opening of the grippers (22) or by the dimensions of the transport means (20). Said means are also stored in such a way that opened grippers (22) are at least partially closed without exercising a holding function in or before the area of the buffer section (14). To this end, a closing device is placed in an entry area (16) of the buffer section (14) which, for example, can be provided in the form of a closing connecting member (18) and can be displaced along the conveying section (10).

  • Patent number: 6290227
    Abstract: Both limbs of the clamp (2, 3), which are pivotally arranged on the axis of a bearing, are rotated from a closing position into an open position and vice versa by an actuating device (12). The actuating device (12) can be displaced from a top end position (13) to a lower end position (14). The actuating device (12) exerts a closing or clamping force on the outer side (22, 23) of the limbs of the clamp (2, 3) in said lower end position (14). When the actuating device (12) is displaced to the top end position (13), an expanding element (15) arranged between the limbs of the clamp (2, 3) comes into contact with the inner side (24, 25) of the limbs of the clamp (2, 3) and exerts an opening force on the limbs of the clamp (2, 3) so that said limbs (2, 3) are swung at a large angle (&agr;) in their open position.

  • Patent number: 6270076
    Abstract: The conveyor line (1) of a conveyor has a branching point (6) with a switch (7). This switch has a pivotable switching member (8) which in one position lies in this conveyor line (1) and in the other position connects this first conveyor line (1) with a second conveyor line (10). Preceding the branching point (6) is a retaining member (11) that can be inserted into the path of movement of the transport elements (2) conveyed along the conveyor line (1). This retaining member (11) can be used to hold back the transport elements (2) approaching the branching point in order to create room for changing over the switching member (8). The transport elements are independent of one another, which makes it possible, selectively and as required, either to move the oncoming transport elements (2) along the first conveyor line (1) or to divert them into the second conveyor line (10).

  • Patent number: 6237744
    Abstract: At a delivery station (1), printed products (4) are unwound from a product reel (6) and transferred to a transfer area (11) of a conveying system (12). The latter has transport members (13) provided with controllable grippers (15) moved by conveying means (19, 19a) or by the force of gravity along a path of transport (14) designed as a closed loop. The printed products (4) are transferred at a delivery area (21) to a further processing device, for example an insetting or collecting drum (28). A buffer section (23), along which the transport members (13) are stored by reducing their mutual distance, is arranged upstream of said dispensing area (21). While an empty winding core (8) is exchanged for a full product reel (6), the supply of printed products (4) to the transfer area (11) is interrupted. During that time, the transport members (13) carrying printed products (4) are taken from the buffer section (23), ensuring a continuous supply of printed products (4) to the delivery station (21).

  • Patent number: 6003859
    Abstract: A conveyor (10) has a self-contained main conveyor line (12), a number of feed lines (14, 14') in the form of buffer lines and a return line (16, 16'). Each feed line (14, 14') is associated to a processing station (26, 26'). The feed lines (14, 14') are connected to the main conveyor line (12) by means of controlled switches (28) so that, viewed in the conveyor direction (F), any of the clamps (20) can be delivered to any desired processing station (26). This gives the device great flexibility and decouples the processing stations from the pickup of the pressroom products at the pickup station (24).

  • Patent number: 5722655
    Abstract: Sheet-like products are fed to the transfer location by a first conveyor. A detector arrangement determines the spacing between the products and controls the first predetermined speed of a second conveyor correspondingly, with the result that, at the transfer location, the formation of the products have a predefined spacing. If the second conveyor is driven, at the stationary transfer location, at the first predetermined speed which differs from a second predetermined speed at the stationary discharge location, the conveying length of the second conveyor changes, thereby displacing a deflection wheel. Different spacings between fed products can thus be evened out.
