Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a stopper device for a folding impeller of a rotary printing press.

[Prior Art] A conventional folding machine impeller in a rotary printing press will be described with reference to Figs. 3 and 4. A signature transfer belt device 31 of a folding machine continuously outputs a signature 32 to a transfer belt thereof. The lower part of the device 31 is dropped between the blades 34a, b, c, which are continuously mounted on the outer periphery of the rotating impeller 33 at equal intervals, and the impeller 33 rotates to lower the lower part. The signatures are being dropped one after another on the delivery table 35 for transporting the signatures. The paper delivery table 35 is composed of an endless belt 36 that moves at a constant speed, and transports the signatures at a constant speed.

A plurality of stoppers 37, each of which is a long thin plate bent at an acute angle of 30 to 70, are provided in the width direction of the delivery tray 35 on the leading side of the top of the delivery tray 35 in the middle of the delivery tray 35 and the impeller 33. Individually arranged, impeller 33
When the signatures 32 are dropped onto the paper ejection tray 35, the tips of the signatures 32 collide with the stoppers 37 in parallel and the signatures 32 are aligned and placed on the paper ejection tray 35.

[Problems to be Solved by the Invention] However, in such a conventional stopper device for a folder impeller, as described above, the fixed stopper 37 is attached to the leading side of the upper signature of the sheet discharge tray 35. For stopper
There is a gap between the bottom edge of 37 and the paper output tray 35 for signatures to pass through.
The signatures that collide with the stopper 37 rebound and fall on the paper ejection tray 35, so that the signatures are misaligned and the continuously falling signatures overlap and are transported on the paper ejection tray 35. Therefore, when passing through the gap d between the lower end of the stopper 37 and the discharge tray 35, there is a problem that the lower end of the stopper is caught and a paper jam occurs.

An object of the present invention is to eliminate the misalignment of the signatures on the signature transfer / delivery tray in the stopper device of the conventional folding machine impeller and to prevent the occurrence of a paper jam of the signature. It is to provide a stopper device.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a stopper device for a folder impeller according to the present invention is arranged such that signatures continuously ejected from a folder impeller of a rotary printing press are aligned in a lower portion. In a stopper device for aligning the leading ends of the signatures by dropping the signatures on a discharge tray composed of an endless belt for transporting signatures, the signature is placed on the discharge tray and rotates at the same speed as the transport speed of the discharge tray. A plurality of stopper rollers arranged in the width direction of the paper ejection table, one end of which is rotatably attached to each of the stopper rollers, and the other end of which is rotated by a support shaft attached parallel to the rotation axis of the impeller. It is characterized in that it has an arm that is supported freely and a clamp lever that fixes the arm on the support shaft so as to maintain the position once set.

[Operation] According to the present invention, the slender plate is rotatably attached to the support shaft in place of the fixed stopper which is bent, and a plurality of members can be fixed at arbitrary positions of the rotation by a clamp lever. Since a plurality of stopper rollers that are rotatably attached to each arm and rotate at the same speed as the paper ejection tray transfer speed are placed on the paper ejection tray and arranged in the width direction of the paper ejection tray, eject from the impeller. The folded signatures hit the stopper rollers, and are continuously and directly underneath and fall onto the paper ejection tray with good alignment, and the paper is neatly sandwiched between the endless belt and the stopper rollers on the paper ejection tray and transported in an orderly manner.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Upon receiving the signatures 32 continuously discharged from the transfer belt device 31 for transferring the signatures folded by the folding machine, the signatures 32 are successively dropped onto the discharge tray 35, and a plurality of blades 34a are continuously arranged at equal intervals on the outer circumference. ,
A plurality of stopper rollers are provided on a delivery table 35 having an endless belt 36 at the bottom of an impeller 33 provided with b, c ...
Arrange in the width direction. This stopper roller 11 is used for the paper ejection stand 35.
It rotates at the same speed as the transfer speed of the upper endless belt 36. The stopper roller 11 is rotatably attached to one end of an arm 12, and the other end of the arm 12 is rotatably supported by a support shaft 13 mounted parallel to the rotation axis of the impeller. A clamp lever 14 is attached to fix the arm 12 on the support shaft 13 so as to keep the position once set. As a result, the signatures that are continuously discharged from the impeller 33 are sequentially applied to the stopper roller 11
It can be stably transferred by aligning it and dropping it, and inserting a signature between the endless belt 36 and the stopper roller 11. Also, depending on the type of signature, loosen the clamp lever 14 and rotate the arm 12 to easily adjust the force for pressing the signature that passes through the gap between the stopper roller 11 and the paper ejection tray 35. You can

[Effects of the Invention] As described above, according to the present invention, a plurality of stopper rollers that rotate at the same speed as the paper ejection tray transfer speed are placed on the paper ejection tray, and are arranged from the folder impeller. Align the ejected signatures and drop them on the paper output tray, then gently slide them into the gap between the stopper roller and the paper output tray, and rotate the stopper roller to eject the signatures without jamming. Therefore, there is an effect that it is possible to provide a stopper device for a folder impeller, which can eliminate the misalignment of the signatures on the delivery tray and prevent the jam of the signatures in the stopper portion.
