Definitions
- the invention relates to a device for adjusting the folding mechanisms a folding cylinder of a folder according to the preamble of claim 1.
- From DE-OS 21 57 615 is a generic, especially the Format setting in the folder serving device known for Realization of a ratio of 1: 1 between the coaxial Drive gears of two interconnected, each in pairs arranged jaw systems possessing a cylinder body Folder cylinder with two connected in series Geared according to the harmonic drive principle.
- the invention has for its object a device for adjusting the Folding mechanisms on a folding cylinder of a folder according to the Generic preamble of claim 1, which with relatively few components and Gear meshing of the components a simple, space-saving structure and a has little play between the components.
- the invention enables with a simply designed harmonic drive gear the adjustment of two cylinder bodies of a folding cylinder within a large one Adjustment range and is therefore particularly suitable for changing the format Folding cylinders suitable.
- the jaw systems can be one Folding jaw cylinder or the folding knives and the punctures of a puncture folding knife cylinder for a pre-fold adjustment or a change to one Adjust the delta fold easily.
- the gearbox has because of the few Tooth meshes a little play, builds compact and is therefore space-saving.
- Fig. 1 shows a cutting cylinder 1 for cutting a paper web 2 in Cooperation with a puncture folding knife cylinder 3, the one Folder cylinder 4 is arranged downstream.
- the puncture folder cylinder 3 creates a cross fold in cooperation with the jaw cylinder 4 the copies cut by the cutting cylinder 1.
- a gripper folding knife cylinder 5 works with Folder cylinder 4 together. Then the copies of one Sheet guide 6 designed in the direction of the arrow.
- the puncture folder cylinder 3, the jaw cylinder 4 and the gripper folder cylinder 5 each consist of two mutually adjustable Cylinder bodies 7 and 8; 9 and 10; 11 and 12.
- the cylinder body 7 has three Rows of puncture needles 13 with the cutting blades 14 of the cutting cylinder 1 work together. If the fold is shifted with respect to the Puncture needles 13, the cylinder body 8 with the folding knives 15 of the puncture folding knife cylinder 3 and by the same angular amount as with jaws 16 equipped cylinder body 9 of the jaw cylinder 4 are rotated so that Folding knife 15 the products, not shown, between the folding jaws 16 can introduce.
- the second cross fold guide folding knife 18 of the cylinder body 12 of the gripper folding knife cylinder 5 in cooperation with jaws 19 des Cylinder body 10 of the jaw cylinder 4 from.
- the folding cylinder is driven by means of a gearwheel 20 the drive gear 21 of the cutting cylinder, which is connected to the drive gear 22 of the cylinder body 7 of the puncture folding knife cylinder is engaged.
- the Drive gear 22 is about a to the cutting plane of Fig. 2 in the circumferential direction of the puncture folding knife cylinder 3 arranged offset (Fig. 1), in Fig. 3 as Detail of FIGS. 1 and 2 Harmonic Drive gear X with a Drive gear 23 of the cylinder body 8 connected to a drive gear 24 of the cylinder body 9 of the jaw cylinder 4 and the drive gear 24 in a drive gear 25 of the cylinder body 11 of the gripper folding knife cylinder intervenes.
- the drive gear 24 is also a Harmonic drive gear X 'with a drive gear 26 of the cylinder body 10 of the jaw cylinder 4 in connection, and the drive gear 26 is located itself with a drive gear 27 of the cylinder body 12 of the gripper folding knife cylinder 5 engaged.
- Harmonic Drive gear X; 3 is one of an actuator 28 actuated control shaft 29 with a designated as wave generator 30 elliptical part firmly connected, on which a designated as flexible spline 31, radially elastically deformable, externally toothed, ring-shaped part rotatable is stored.
- the circular spline engages in the external splines of the Flexible Spline 31 Spline 32 designated outer ring with a flexible spline 31 opposite have a larger number of teeth internal teeth.
- the Circular Spline 32 is equipped with an external toothing, which with the drive gear 22 of the Puncture folding knife cylinder 3 or the drive gear 26 of the The jaw cylinder 4 is engaged.
- the flexible spline is a coaxial to the circular spline 32 on the adjusting shaft 29 mounted gear 33 firmly connected with a translation between the Flexible Spline 31 and the Circular Spline 32
- Number of teeth in the drive gear 23 of the puncture folder cylinder 3 or the drive gear 24 of the jaw cylinder 4 each Gear ratio 1: 1 between those equipped with the same number of teeth Drive gears 22; 23 of the two cylinder bodies 7 and 8 of the puncture folding knife cylinder 3 or drive gears 24; 26 of the two cylinder bodies 9; 10 of the jaw cylinder 4 engages.
- the difference is between the number of teeth on the external teeth of the Circular Spline 32 and the gear 33 with the same center distances of the circular spline 32 and the Gear 33 to the puncture folder cylinder 3 or jaw cylinder 4 compensated by a profile shift.
- the External teeth of the circular spline 51 teeth and the gear 33 50 teeth is the ratio of the number of teeth of the internal teeth of the circular Spline 32 and the external teeth of the Flexible Spline 31 51:50.
- Circular Spline 32 It is inexpensive to have the Circular Spline 32 in several parts with one Internally threaded ring 34 and a firmly connected to the latter, the Execute externally threaded gear 35.
