Abstract:
The invention relates to a method of, and an apparatus for, conveying sheet like products (10, 10′), in particular printed products. In each case two or more products (10, 10′) are gripped together, in the region of their leading edges (10a, 10a′), by grippers (3) of a gripper conveyor (1) such that the edges (10a, 10a′) are alternately spaced apart from one another. In at least one transfer region (4), the products (10, 10′) are transferred to at least one removal arrangement (2) such that each product (10, 10′) at most partially overlaps the previously transferred product (10, 10′), the leading edges (10a, 10a′) of the products (10, 10′) being spaced apart from one another. The invention has the advantage that the products are directly accessible for further processing.

The invention relates to a method of, and an apparatus for, conveying sheet like products (10, 10null), in particular printed products. In each case two or more products (10, 10null) are gripped together, in the region of their leading edges (10a, 10anull), by grippers (3) of a gripper conveyor (1) such that the edges (10a, 10anull) are alternately spaced apart from one another. In at least one transfer region (4), the products (10, 10null) are transferred to at least one removal arrangement (2) such that each product (10, 10null) at most partially overlaps the previously transferred product (10, 10null), the leading edges (10a, 10anull) of the products (10, 10null) being spaced apart from one another. The invention has the advantage that the products are directly accessible for further processing.
Abstract:
A method and apparatus for conveying printed products in an imbricated formation with different spacings between the products, from a feed conveyor to the grippers on a removal conveyor. The printed products are introduced into the grippers in groups without any change in the spacing between successive printed products, and the conveying speeds of the feed conveyor and the removal conveyor are coordinated such that the portion of each group of products which projects into a gripper is less than the depth of the mouth of the gripper. Also, a deflection device at the transfer location serves to deflect the leading end of each group of products toward the approaching gripper. Alternatively, the grippers are controlled so that in the transfer location, a leading clamping part of the approaching gripper engages a trailing clamping part of the preceding gripper so as to guide the next group of products into the mouth of the approaching gripper.
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:
A device according to the invention for monitoring two sheet products transported by means of a clamp of a transport device. The device has at least two sensors that are intended to generate signals on the basis of which the number of products held in the clamp can be determined. A first sensor hereby generates a first detection signal referred to as reference signal when a clamp passes a reference area assigned to this first sensor. The second sensor is arranged in such a way that it generates a second detection signal when at least one section of one of the products in a second side edge area free from the clamp passes through its assigned detection area.
Abstract:
An apparatus and a method for transferring flexible flat objects, in particular printed products, between two conveyers wherein the apparatus includes a first gripper conveyor having first grippers moved along a first gripper conveying path for the substantially suspended transport of the objects in a conveyor device by seizing a first object edge, a second gripper conveyor having second grippers moved along a second gripper conveying path for receiving the objects by seizing a second object edge located opposite of the first object edge, at least one actuating apparatus for opening and closing the first and second grippers such that a transfer of the objects from the first grippers to the second grippers can take place in a transfer region. At least one auxiliary conveyor including auxiliary grippers carried along an auxiliary conveyor conveying path together with the first grippers is provided.
Abstract:
The invention relates to a collating apparatus (90), which includes a conveying track on which, in a closed circuit, a multiplicity of receiving units (13) arranged one after another in the direction of circulation to hold pre-products to be collated circulate, and on which, in at least one collating region (94, 95, 96), a plurality of feed devices are arranged one after another in the direction of circulation, from which pre-products are discharged into the receiving units (13) moving past on the conveying track. In such a collating apparatus, flexible operation is made possible in that the receiving units (13) are conveyed on the conveying track by means of a three-dimensionally flexible, preferably chain-like, conveying element, in that the receiving units (13) in each case have clamping means, which hold the pre-products collated in the receiving units (13) in a clamped manner, and in that at a plurality of points of the conveying track there are arranged transfer devices (91, 92, 93) which transport collated pre-products away from the receiving units (13) for post processing.
Abstract:
The device (10) according to the invention for counting and detecting flat products (14) comprises a light source (16) having an illumination beam profile (24), an optical sensor (18) having a detection beam profile (30) and an evaluation unit (20) connected to the optical sensor (18). The detection beam profile (30) overlaps the illumination beam profile (24) in a detection region in which a section (33) of a surface profile of the flat products (14) is illuminated, the section being at least partially delimited by the illumination beam profile (24). A detection signal generated by the optical sensor (18) is fed to the evaluation unit (20), which determines therefrom the number of flat products located in the detection region.
