Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a temporary bypass device for paper sheets including postal envelopes and postcards, which can be applied to commercial rotary presses, paper sheet processing equipment, and the like.

The conventional commercial rotary press has the symbol (8) of the device shown in Fig.'1.
) ~ There was no temporary bypass device shown by the fence. When it becomes necessary to remove printed matter from the system due to inspection of the finished state of printing, adjustment, paper splicing, stacker malfunction, etc., use the rotary press folding machine conveyor (5) or the stacker conveyor (5).
6) The printed matter being conveyed in a scaly manner had to be manually pulled out.

However, it is difficult to extract the required number of printed matter from the scaly wrapped printed material, and the rows of printed matter before and after the removed printed material are disordered, and when stacked in the stacker, Line stop due to print jam,
Problems such as the stacked bundle of printed matter becoming disordered occurred. In particular, a large number of printed matter must be sampled during paper splicing, printing preparation adjustment, stacker malfunction, etc., and it has been extremely difficult to obtain and sample them in a short period of time.

The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and between the conveyor belt and the impeller that rotates and carries the paper sheets downward, the paper sheets are transferred to the impeller side or outside the machine. By providing a movable guide, paper sheets can be easily removed.
It is also an object of the present invention to provide a temporary bypass device for paper sheets that does not cause disturbance in the stacked bundle of paper sheets.

The present invention will be explained below with reference to the embodiments shown in the drawings. Figures 1 and 2 show embodiments of the present invention, in which (1) is the folding machine body of a rotary press, (2→(2b) is a folding machine for folding printed matter). A bell that transports horse mackerel from the machine's gripping body (not shown) to the impeller (3))
, (4) is the printed matter c2 carried by the impeller (3).
This is a stopper for dropping α onto the folding machine belt conveyor (5), and is provided between the blades of the impeller.

(6) is the conveyor of the stacker, (the force is the guide of the printed matter,
(8) swings between A1B1I around the shaft (9), and when the printed material is temporarily discharged from the system, it is at position B and guides the printed material from the belt (2α) (2b) to the belt screaming α wound. The tip consists of an arc-shaped plate with a large radius and slightly wider than the width of the printed material. (II is a lever for swinging the guide (8), which swings integrally with the guide (8) around a shaft (9) attached to one end, and the other end is connected to a solenoid via a link 0υ. 03, a return spring Oa is attached to the same link 0υ.

The other end of the return spring (14) is fixed to a spring mounting rod θ attached to the frame 03);
is attached to the folding machine body (1). a6) (The fixed side and the printed matter guide, together with the movable side guide (8), guide the printed matter. αD is the belt (2g), the axis (2c), and the heald aIlo (11).
) A belt that transmits driving force to drive shafts (18α) (19c), a8) H is a belt that pinches and conveys printed matter when temporarily discharging printed matter, and shaft (18 (194)) drives the belt (2a) ) is driven at the same speed as (2b). (2]) is a photoelectric switch that detects the passage of printed matter;
Two are boxes that house printed matter.

Next, the effect will be explained. First, normal operation will be explained with reference to FIG. 1. Printed matter (A) discharged from the gripper cylinder of the rotary press folding machine is held by belts (2α) (2+5) and conveyed to the impeller (3). The printed matter placed in the impeller (3) is carried below the impeller by the rotation of the impeller (3), and then falls onto the conveyor (5) by the stopper (4).

The printed matter that fell onto the conveyor is the dirt of the folding machine belt conveyor (5) (2a) (2b). Since it is moving at a moderate speed, it is transported in the form of scales and transferred to the stacker conveyor (6). At this time, the guide (8) is in the A position due to the solenoid (13 is not energized and the return spring 04).

Next, I will explain the temporary bypass. When inspecting the finished state of printed matter or adjusting print preparation, it is operated by the operator, and when splicing paper, it is transmitted from the rotary press signal, and when there is a problem with the stacker, it is controlled by the operator's command or by the stacker. The signal causes the temporary bypass device to bypass the printed matter out of the machine instead of flowing it into the stacker.

That is, when a bypass command is received, the photoelectric switch (2I)
After detecting the passage of the front end of the printed matter (2), and after a delay time corresponding to the printing speed, the solenoid Q2 is energized. This is controlled by a control device (not shown). When solenoid a2 is energized, its attraction force is the link 0υ
, the lever α is transmitted to the guide (8), and the guide (
8) swings around the shaft (9) and moves from position A to position B.

Therefore, the printed matter (to) which has been carried from the belt (2α) (2b) to the impeller is guided by the guide (8) and the fixed printed matter guide aQ, and moves to the belt a8α9. Printed matter (A) moved to belt α8 (19) is carried outside the machine and stored in a box (C). Printed matter (■) may be taken out from the box (2Z), and if necessary, it can be further handled on a conveyor. It may also be carried to a convenient location.

Next, when there is no longer a need for a temporary bypass and the operator performs a return operation, or a return signal is issued from the rotary press or stacker, the photoelectric switch (2I) detects the passing of the front edge of the printed material (20), and then the printing speed increases. After a delay time corresponding to
The solenoid 03 is demagnetized, and the return spring 04) returns the solenoid a2) and the guide (8), and the guide (8) returns to the A position, and the printed matter enters the impeller (3) again, returning to the normal operating state. (Figure 1).

When energizing or demagnetizing the solenoid 1 to swing the guide (8), the guide (8) has a delay time depending on the printing speed after the photoelectric switch (2I) detects the passage of the printed material. ) moves from position A to position B or returns from position B to the human position, the guide (
8) in order to oscillate it.

The present invention is constructed as described above in detail, and there is no need to remove paper sheets that are being conveyed in a scaly manner when they are obtained, so that the rows of paper sheets are not disturbed. Therefore, there is no line stoppage or disturbance of the stack of printed matter due to clogging of printed matter during the stacking in the stacker.

In addition, when splicing sheets or in the event of a problem with the stacker, the sheets are automatically bypassed out of the system by a signal from the rotary press or stacker, reducing the burden on operating personnel. and when inspecting the printing finish,
At the time of print preparation adjustment, etc., the operator can simply press a button.
The required number of paper sheets can be easily removed when needed, completely eliminating the problems encountered in the past. In the embodiment described above, a stacker for printed matter has been described, but the present invention can also be applied to processing of mail items (postcards, envelopes), banknotes, etc.
