Abstract:
A device for buffering a plurality of goods or groups of goods includes a buffer section configured to receive a plurality of goods or groups of goods. In addition, a buffer transport is provided, configured to move a good or group of goods at a buffer transport speed. A runout is configured to move out a good or group of goods from the device at a runout speed which is higher than the buffer transport speed. The runout is additionally configured to take over transport of a good or group of goods before the good or group of goods has reached an end of the buffer section.
Abstract:
A method and a device for the conveyance of planar products (10, 10′, 20, 20′), in particular printed products, are provided wherein a product group (100) composed of at least two products (10, 10′, 20, 20′) is gripped by a gripper (42) in the area of a product edge (12, 12′, 22, 22′) and conveyed in a direction of conveyance (F2). At least one of the products (10, 10′, 20, 20′) is displaced relative to the other product or products (10, 10′, 20, 20′) in the product group (100) in a direction of displacement (A) defined by the gripped product edge (12, 12′, 22, 22′), such that in each case a projection (14, 24) is formed in the direction of displacement (A). Thus a first projection (14) is associated with at least one displaced product (10, 10′, 20, 20′) and a second projection (24) is associated with the remaining product or products (10, 10′, 20, 20′) of the product group (100). Thus, it is easy to increase the carrying capacity of a gripper conveyor and, when applicable, to easily separate the products that are gripped in groups.

Abstract:
The invention relates to a method and to a device for processing and separating an imbricate formation of flexible, flat objects 10, in particular of folded printed products. The imbricate formation is influenced by way of a guide means 1 which at least in regions is inclined with respect to the horizontal such that the objects are differently inclined with respect to the vertical. The guide means 1 serve for reforming the flat objects of the imbricate flow in angle and alignment, wherein at its end there is effected a removal of individual or groups of flat objects. At the end of a guide surface 2 of the guide means 1 there is arranged a conveyor means 9 which serves for conveying away the isolated objects 10.
Abstract:
The invention refers to a method and an apparatus for gathering flat printed products by selecting a single printed product from each of a multitude of collections of identical printed products and conveying the selected printed products towards a collecting conveyor (10), which runs along a generally straight line in a first direction (11).To improve the transfer of the flat printed products to the downstream machinery, it is suggested to advance the printed products in a second direction (15) in a continuous flow of printed products with a feeder (1) with feeding elements upstream of the collecting conveyor (10), grip a leading portion (20) of a printed product at the discharge end of said feeder (1) by separating grippers (60) of a transferring conveyor (40) which is also arranged up-stream of the collecting conveyor (10) and transfer the gripped printed product with the transferring conveyor (40) substantially along a path, which takes its course generally along the first direction (11) of the collecting conveyor (10).
Abstract:
The invention relates to a device for conveying flat objects (46), especially products of a printing works, which comprises successively arranged conveying elements that are moved along a continuous track (16) in a direction of conveyance (F). Individually controllable conveying clamps (22) are mounted on each conveying element (12) and are configured for laterally holding, with the clamp jaw thereof that is arranged in the plane of conveyance extending in the direction of conveyance (F), at least two objects (46), which are arranged in the plane of conveyance and in the direction of conveyance (F) while overlapping one another in an offset manner. The conveying clamps are mounted on the conveying elements in the plane of conveyance and in a direction of displacement (30), which is perpendicular to the continuous track (16), in a manner that permits them to be displaced to and fro between two positions (50, 50′). A control device (53) is configured for displacing the conveying clamps (22) from one position (50, 50′) into the other.
Abstract:
For conveying flat articles (10) in dense conveying streams, grippers (3) conveyed one behind the other by conveying elements (1) are used, each gripper (3) holding one of the articles gripped in an edge zone. For increasing the possibilities for changing the orientation of the flat articles (10) during such conveyance, the grippers (3) are attached to the conveying elements (1) by asymmetrically-projecting gripper arms (2) and the grippers (3) are designed to be rotated through 360° around the gripper arm axis. The device can be used universally, particularly for held conveyance of printed products and it is very easily adjustable for differing applications.
Abstract:
The transporting apparatus has a guide which forms a closed loop and in which transporting members circulate. The transporting members are driven at the beginning and end of the effective conveying zone by in each case an independently controllable drive mechanism. Between successive transporting members there are in each case spring elements, which are designed exclusively for the transfer of compressive force. The drive means of the drive mechanisms driving the transporting members are preceded by controlled blockers, by which the transporting members are prevented from being taken along by the drive. As a result it is ensured that each transporting member seizes a printing product, even if there are gaps in the printing products as they are fed to the transporting members, the printing products preferably being fed in imbricated formation. At the delivery point, the delivery of printing products may also be delayed by one or more cycles without stopping the drive. The spring elements allow a differing number of transporting members to be located between the drive mechanisms.
Abstract:
The system for error management for the further processing of an imbricated stream (S) of printed products has an observation element (1), which generates a measuring signal correlated with the imbricated stream. The measuring signal is interpreted clock by clock by an interpretation element (2) by edge and/or amplitude scanning. If a clock of the measuring signal does not have the correct number of edges or a maximum amplitude lying outside a tolerance range, error signals are generated and sent to a control element (3). The control element (3) generates control signals corresponding to the error signals for at least one controlled element (10, 20, 30), which is arranged downstream from the observation element (1) in the stream of products, by delaying the error signal essentially by the distance between observation element (1) and controlled element (10, 20, 30). The controlled element (10, 20, 30) eliminates places where errors have occurred or transforms them into places of different errors. The system serves for detecting, transforming and/or eliminating gaps, places occupied by defective products, places occupied by an incorrect number of products and/or places occupied by products displaced in the conveying direction, of the imbricated stream.
Abstract:
A conveying apparatus delivers a succession of printing products in a first imbricated formation to a take-over region where the products are transferred to a delivery conveyor and conveyed away in a second imbricated formation. In the takeover region, the successive products are formed into an arched configuration, when viewed perpendicularly to the direction of their travel. This assists in ensuring that the products are delivered singly to the delivery conveyor even if the products are received at the takeover region in congruent fully overlapping pairs.
