ている。The above-mentioned prior art has the following problems. When performing non-overlapping / overlapping with the needle cam and folding blade cam of the folding cylinder, a non-overlapping cam and a superposition cam are provided for each of the needle cam and folding blade cam, and these cams are exchanged. The switching is performed more or less, or vice versa. This cam replacement work
Since it is performed in a small space, it is cumbersome, requires special tools, and takes a considerable time (about 30 minutes) for cam replacement. Further, the needle cam is switched between rotation and stop and fixed by a clutch, and only the overlapping cam is used as the needle cam.

われない。On the other hand, the profile (recess) of the needle cam is set on the basis of rotation. Therefore, the relative speed of the cam follower passing through this profile is such that when the cam is rotating, the folding cylinder is 120 ° while the cam rotates 180 ° as described above.
° rotation, the difference between the cam rotation speed 1.5v and the rotation speed v of the folding cylinder is 0.5v. When the cam is stopped, the rotation speed of the cam is zero. Based on the passing speed of the cam follower, the cam follower operates as if the profile of the cam is different during fixing, so that the behavior of the needle is different. In other words, the needle comes out faster than at the time of rotation at the time of fixing, so the folding operation of the folding blade operated by the rotating folding blade cam and the operation of the needle at the time of fixing do not match in time, and the folding is smooth. Not done.

を目的とするものである。Further, in order to switch the needle cam and the folding blade cam between non-overlapping and overlapping, the non-overlapping cam and the overlapping cam of each cam must be exchanged. Requires at least two workers. The present invention switches between the fixed cam and the rotating cam with the one-point clutch, thereby eliminating the need to replace the non-stacking cam and the stacking cam. It is an object of the present invention to provide a non-overlapping / overlapping switching device for folding cylinders capable of switching.

Allow the cam follower to move in a non-overlapping manner
Is provided on the frame supporting the folding cylinder.
A first rotating cam independently rotatably supported;
1 side by side and fixed to the frame
The concave portion is aligned with the concave portion to supplement the concave portion and overlap the cam follower.
A first fixed cam for causing the operation and a second fixed cam provided on the other end surface of the folding cylinder;
Into a substantially circular shape, and around the
Non-overlapping motion on the cam follower by allowing the
There is a concave part to wake up, and the frame is
A second rotating cam supported upright and rotatably, and the second rotating cam;
Of the rotating cam and fixed to the frame,
Movement that matches with the recess and supplements the recess to overlap the cam follower
And a second fixed cam for causing the first and second rotations.
The first and second fixed cams are matched with the concave portions of the rolling cams, and
Release the needle device and folding blade device.
Switching between overlapping and non-overlapping of paper depending on the position eliminates the need to replace the non-overlapping cam and the overlapping cam, and switches over between the needle cam and folding blade cam at a predetermined timing. Can be. Also, a set of 2 provided on the folding cylinder overlapping / non-overlapping switching device is provided.
With the point clutch, it is possible to simultaneously switch to the overlapping or non-overlapping position by one operation. Therefore, the switching between the overlapping and the non-overlapping can be easily performed in a short time.
