Problems solved by technology

The problem with the solution described above is that, due to the inherent mass of the mechanical parts required for force conversion, high forces are required, which adversely affects the dynamic behavior and accuracy of the hinge braces and when additional stops and damping elements are used will cause high wear as well as vibration and noise
The disadvantage of this configuration of the folding knife drive is that, due to the parallel arrangement, the drive part of the linear motor and the folding knife are not easily accessible, and consequently the resulting thermal issues

Embodiment Construction

[0031]The folding knife drive shown in FIG. 1 is an integral part of a knife folding mechanism, in which the printed sheets guided by a not shown conveying system in the printed sheet plane 2 are transported by a pair of sheets arranged below the printed sheet plane 2. Rotating roller folding. The folding knife 1 presses the printed sheet into the gap formed between the rollers until the printed sheet is gripped by the rollers. For this purpose, the folding knife 1 is reciprocated between two end positions in a drive direction extending perpendicularly to the printed sheet plane 2 . The drive movement for driving the folding knife 1 is produced by a linear drive 3 designed as a linear motor, which comprises a linear drive stator 4 and a linear drive mover forming an output output unit 5 . The linear motor is arranged with its axis of motion extending approximately in the drive direction beyond the midpoint between the two ends of the folding knife 1 . On both ends of the fol...

Abstract

The folding blade drive for a folding machine has a linear drive (3) including an output component (5), the axis of movement of which extends in the drive direction. At least one drive element (6.1,6.2) in the form of a belt or band runs over rotatably mounted deflection elements (7.1-7.8) in the form of pulleys or rollers and is connected to the fold blade (1) and to the output component of the linear drive, and through which the movement of the output component is transferred to the fold blade through reversal of the direction of movement.

Description

technical field [0001] The invention is used in combination folders operating mainly on the knife-folding principle, in which a flat material is folded between rotating rollers. In particular, the invention relates to a folding knife drive of a folding machine with a linear drive, by means of which a folding knife guided in a linear guide is driven. Background technique [0002] The prior art discloses variants in which the folding knife is driven by means of a main drive which generates a rotational movement which can be transformed by means of a suitable gear unit. In this case, a slider crank mechanism or a crankshaft mechanism can generally be used as the transmission unit. Depending on the design, the folding knife driven by it and guided in a linear guide can either fold the pages rhythmically - which can cause problems in the case of uneven sheet sequences - or can be provided with additional sensors which detect The position of the printed sheet and the knife foldi...
