DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a cylinder for a folding apparatus. The cylinder carries controlled gripper systems and folding blade systems. These gripper systems and folding blade systems are operated by control cams which rotate in the same direction as the cylinder, and which are attached to each other.
DESCRIPTION OF THE PRIOR ART
From Examined, Published German Patent Application DE-AS 10 76 712, a folding apparatus of this general type, with an arrangement for controlling grippers and folding blades, that is located on the collecting cylinder, is known. The signature feeding device and the folding blades are actuated by means of drive shafts, roller levers, and cam rollers connected to them and each rolling on two control cams.
A disadvantage of this folding apparatus is the major expense for mechanical parts, such as gearing, for driving the rotatable control disks of the signature feeding means, and folding blades for collect-run production. Furthermore, major wear occurs at the cam rollers and control cams.
U.S. Pat. No. 3,865,361 describes a folding cylinder with point needle gripper systems and folding blades. The point needle gripper systems are controlled by control cams and cam rollers, and the folding blades are driven by a toothed gearing system.
U.S. Pat. No. 3,263,988 shows a folding cylinder with a variable-diameter jacket face.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a simple, low-wear drive mechanism for controlled assemblies, as they are called, such as folding jaws, sheet grippers, point needles, and so forth on a cylinder of a folding apparatus.
This object is attained according to the invention by the provision of various controlled assemblies that are operated through cain rollers which roll on rotary control cams. These control cams are supported on the cylinder journal and have the same direction of rotation as the cylinder. The various control cams for the several controlled assemblies on the cylinder are connected to one another.
The advantages attainable with the present invention are, in particular, that a simple drive mechanism can be employed that avoids major expense for gearing. Furthermore, the wear of the cam gear for the drive of the signature feeding means and of the folding blades is reduced, because there is a lower relative speed between the control cams and cam rollers. It is possible to recouple to change over from collect-run to non-collect-run production over a relatively wide angular range.
The cylinder makes a simple, low-arm drive mechanism possible for the cam-controlled assemblies, such as controlled folding jaws, grippers, point needles, and so forth.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the present invention is shown in the drawing and will be described in further detail below.
Shown are
FIG. 1, a schematic illustration of a folding apparatus of the present invention in the "non-collect-run" type of production, in a first operating position;
FIG. 2, a view corresponding to FIG. 1, but in a second operating position, in which the collecting cylinder has been rotated onward by 240.degree. and the control cams and the cutting and folding jaw cylinders have been rotated onward by 360.degree.; and in
FIG. 3, a plan view on the cutting and collecting cylinder of FIG. 1, showing the control cams and cover disks in the "collect-run" type of production.
DESCRIPTION OF THE PREFERRED EMBODIMENT
A folding apparatus 1 comprises an n-piece, for instance three-piece folding blade and transport cylinder 2 for signatures, and both a cutting cylinder 3, for instance in two parts, and a folding jaw cylinder 4, also for instance in two parts, may be associated with the folding blade and transport cylinder. The folding blade and transport cylinder 2 may be embodied as a collecting cylinder, all as seen in FIGS 1 and 2.
The folding jaw cylinder 4 has two rows of folding jaws 6, 7, offset from one another by 180.degree., on its circumference.
The cutting cylinder 3 has two cutting
