Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge path switching device for a signature in a folding machine of a rotary printing press.

[Conventional technology]

A device disclosed in Japanese Patent Publication No. 52-45530 is known as a device for switching the paper discharge path of a signature.

This device switches the path of a signature discharged from a folding roll arranged below the folding cylinder to one of two pairs of feed rolls arranged below the folding roll or alternately to feed the signature. A swingable paper guide is arranged between the roll and the feeding roll, the paper guide is rotatably supported by the support shaft of the folding cylinder, and a clutch for transmitting the rotational force to the gear. And a crank supported on a crank shaft driven by a gear transmission including the gear.

With such a configuration, it is possible to easily switch the discharge path of the signature and stop the switching operation by disengaging the clutch.

[Problems to be Solved by the Invention]

However, when the clutch is disengaged and the signature is discharged to one side, when the rotation speed of the rotary printing press increases, rotation of the folding cylinder causes rotation of the gear transmission, which causes the paper guide to swing and cause the signature of the signature to rotate. The discharge route may change.

In view of the above circumstances, an object of the present invention is to enable the discharge path of a signature to be switched by a simple operation and, moreover, to ensure that the set discharge path can be maintained even when the rotary printing machine rotates at high speed. It is an object of the present invention to provide a paper discharge path switching device for a signature in a folder of a printing machine.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, a first gear train that transmits power from a driving shaft of a rotary printing press and a plurality of grooves formed at predetermined intervals, and the power transmitted by the gear train. The drive roller that drives the conveyor that conveys the signature, the clutch mechanism that intermittently moves the power branched from the gear train by moving the clutch gear in the axial direction, and the transmission of the power through the clutch mechanism. A second gear train to be performed, a cam shaft rotated by the power transmitted by the second gear train, a cam fixed to one end of the cam shaft, and a parallel rotation with the drive roller at a predetermined interval. A lever shaft that is movably disposed, a plurality of distribution levers that have one end engaged with the groove of the drive roller and the other end fixed to the lever shaft at a predetermined interval, and one end of the lever shaft. A switching lever having a cam follower that is fixed to the end and engages with the cam at the other end, and a first lock for fixing a notch at one position on the circumference and fixed to the other end of the cam shaft. A disc and a notch formed at one location on the circumference, and an intermediate shaft supporting one of the gears forming the second gear train so that the notch has a predetermined phase with the cam. And a second locking disc fixed to the first locking disc so as to face the first locking disc at a predetermined interval, and a locking member that engages with a notch in each of the locking discs. The member is associated with a first position where the member engages with the notch of the first locking disc and a second position where it engages with the notch of the second locking disc. It was equipped with a lock lever that moves it to a neutral position that does not match.

[Action]

Then, when the clutch is connected and the lock lever is set to the neutral position, the rotation of the driving shaft is transmitted to the cam shaft via the second gear train to rotate the cam. Then, the switching lever is swung by the cam, and the distribution lever is swung via the lever shaft to alternately switch the discharge path of the signature.

Further, the clutch is disengaged, the lock lever is tilted to the side of the first locking disc, and the second gear train is rotated. When the lock member is fitted into the notch of the first locking disc, the rotation of the second gear train is restricted, and at the same time, the position (or the position where the switching lever engages with the groove of the drive roller). (Position away from the drive roller).

Further, the clutch is disengaged, the lock lever is tilted to the side of the second locking disc, and the second gear train is rotated. Then, when the lock member is fitted into the notch of the second locking disc, the rotation of the second gear train is restricted, and at the same time, the position of the switching lever separated from the drive roller (or the drive roller (Position where the groove is engaged).
