Abstract:
An apparatus for conveying and discharging flat, preferably flexible articles, in particular printed products, the apparatus including a plurality of grippers which can be moved in a conveying direction (F) along a continuous conveying path (U) defined by a conveying mechanism. The grippers include a first gripper jaw and a second gripper jaw, which can assume a clamping position and an open position relative to one another. The first gripper jaw is longer than the second gripper jaw and includes a first gripper part, which in the clamping position interacts with the second gripper jaw, and a second gripper part, which in the clamping position projects beyond the second gripper jaw. The orientation of the first and second gripper parts of the first gripper jaw relative to one another is variable and can be adjusted by a control means.
Abstract:
An apparatus and a method for compiling flat objects, wherein a gripper conveyor is used, the grippers of which either act directly as support elements or contact surfaces for the products to be compiled, thereby constituting a receiving unit, or interact with a separate support element to form a receiving unit. The use of a gripper conveyor having a controllable opening state and a controllable orientation of the gripper jaws of the individual grippers, and/or a controllable orientation of the separate support elements, has the advantage that the orientation of the contact surfaces and the clamping function within a receiving unit can be set independently of the adjoining receiving units. In this way, greater flexibility is attained.
Abstract:
A number of circulatory elements arranged one behind the other are driven in a direction of circulation and have a suction element and a supporting element in each case on the first side and on the second side. The circulatory elements receive a supplementary product at the pick-up location and transfer the same, in a first mode of operation, to the respectively preceding circulatory element. In a second mode of operation, no transfer takes place. This results in it being possible for the supplementary products received in the same manner to be brought into abutment optionally against the leading side or trailing side of the printed products and pressed on there.
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 process and apparatus for conveying flexible sheet-like articles 26, wherein the articles are fed to a first curved section 14 by means of a delivery conveyor 10 which includes spaced apart transporting clamps 22 for retaining the articles in a hanging position. Arranged in a radially inward direction at the curved section 14, is a gripper wheel 36 with circumferentially distributed grippers 40 and respective supporting elements 52. The gripper wheel 36 is driven at the same angular velocity as the transporting clamps 22 in the curved section 14. However, a single gripper 40 is assigned in each case to two transporting clamps 22. The lower free edges 32 of the two articles 26 to be joined are guided by a supporting element 52 into a gripper 40, and as soon as this has taken place, the relevant gripper 40 is closed, and the relevant transporting clamps 22 then release the articles 26. The associated supporting element 52 is then drawn back inward in the radial direction.

The two articles retained by a gripper 40 then may be transferred to the transporting grippers 58 of a removal conveyor 56 for being transported away, or where the grippers are mounted on an endless conveyor 42 the articles may be transported away by the endless conveyor. Alternatively, the joined articles may be transferred back to alternate clamps of the delivery conveyor.
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:
In each case at least two objects arriving in a lamellar flow (14) are grasped from the side by a conveyor clamp (22) and conveyed further while maintaining their mutual position. The at least two objects forming a section are held by a single conveyor clamp in a clamping area (30) where the objects (14) overlap.
