Abstract

PURPOSE:To safely perform paper temporarily receiving operation so as to stabilize the operation by enabling a paper temporarity receiving member having one end fixed stationarily and the other end journalled so as to allow wind-up and pay-out, to be returned and stored outside of a paper discharge section in association with the forward and backward motion of a mover. CONSTITUTION:A mover 12 which may be moved back and forth in a horizontal direction along the lower side of a delivery chain 4 in a horizontal paper discharge section A is disposed between a stationary section 10 and a roll core section 11. Then, the mover 12 in a freely rotating state is moved back and force so as to horizontally extend a paper temporarily receiving member in the paper discharge section A and to retract it outside of the horizontal paper discharge section A. Accordingly, the paper receiving member can be extended and retracted at a moving speed of the mover 12 which is one.half of the speed of paper printing and discharged. Accordingly the operator does not feel a fear, so that the paper temporarily receiving operation may be safely carried out. Further, since no relative movement is exerted to a printed and discharged sheet, the paper receiving member does not chafe, thereby it is possible to stably carry out the paper receiving operation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a temporary paper receiving device installed in a paper discharge device of a sheet-fed printing press.

(Conventional explanation) When printing paper discharged from the paper discharge section of a sheet-fed printing press is stacked and discharged onto a loading table that can be raised and lowered and moves down intermittently, or onto a pallet placed on the loading table. After a predetermined number of sheets have been loaded and discharged, the pile of printed sheets is carried out from the pallet-by-pallet sheet discharge device by a forklift or the like.
Preparations such as placing the next pallet on the loading platform and raising it to a predetermined height are required. Therefore, until the preparation is completed, it is necessary to temporarily receive the printed paper that is continuously discharged from the printing machine above the pallet.

For example, as shown in FIG. 6, a conventional temporary paper receiving device is installed in a horizontal paper discharging section A of a delivery chain 4 equipped with a paper discharging grip 7 of a printing press discharging section 2, at an upstream side in the paper discharging direction. A horizontal paper receiving plate or comb blade B is provided on the printing unit 1 side,
The plate was shifted horizontally along the lower side of the horizontal paper discharge section A in the direction of paper discharge progress, and the printed paper a released from the paper discharge grip 7 was temporarily received on the plate B.

However, with this type of paper receiving device, if the printing speed is particularly high, the shift speed must be correspondingly fast, so it is difficult for the printing operator located downstream in the paper ejection direction to There is a concern that it may cause a sense of fear, and if the paper ejection speed is high, the paper receiving plate B itself needs to be shifted faster than the paper ejection speed, so it is difficult to determine the timing of the shift and the shift position may be incorrect. Easily stabilized.

(Object of the Invention) The present invention provides a printing paper discharging section which has one end fixed to a horizontal paper discharging section A below the delivery chain, and the other end supported on a roll core or the like so that it can be freely wound and unwound. A temporary paper receiving member such as a rolled sheet can be stretched by the forward and backward movement of the moving body, and can be returned and stored outside the paper discharge section A, so that a printing operator can operate the temporary paper receiving member with peace of mind. Moreover, it is an object of the present invention to enable the shift speed of the moving body to be set relatively low relative to the paper discharge speed, and to enable stable temporary paper receiving operations.

(Structure of the Invention) The present invention provides a movable body such as an elongated roller that can move forward and backward in the horizontal direction on the lower side of the delivery chain horizontal paper discharge section of a sheet-fed printing machine, and the horizontal paper discharge section A temporary paper receiving member in the form of a sheet is provided at the front end or rear end side of the paper, with one end fixed to a fixed part and the other end supported on a rotating roll core so that it can be freely wound and unwound, and between the fixed part and the roll core. A temporary sheet receiving device for a sheet discharge section of a sheet-fed printing machine, characterized in that the movable body is brought into contact with a sheet member and moved forward and backward, and the sheet is moved forward and backward at a lower side of horizontal sheet discharge. be.

FIG. 1 is a side view of an embodiment of the apparatus of the present invention, in which a delivery chain 4 of a sheet-fed printing press discharge section 2 is connected to a chain wheel 5 adjacent to a final impression cylinder 3 of a printing unit 1 of the printing press. The printing paper a, which is endlessly wound around the Chenosu roller 6 at the end of the paper section 2 and printed between the printing units 1, is picked up by the final impression cylinder 3 and into the delivery grip 7 of the delivery chain 4. The printed paper a is changed and delivered to the delivery chain 4 side, and is conveyed to the horizontal paper discharge section A of the paper discharge section 2 by the chain. At this time, the conveyed printing paper a is released at an appropriate timing, and its front end is transferred to the front abutment plate 9. In this case, the side edges are aligned with the side abutment plate and the sheets are successively stacked and discharged onto the pile 24 on the loading table 13 below the stacking plate 13. When the sheets are being continuously discharged onto the sheet discharge bin 24 on the top 13, ribbon-like sheets or scattered ribbons are arranged at appropriate timings under the horizontal sheet discharge section A where the delivery chain 4 moves horizontally. By horizontally extending the temporary paper receiving member from the downstream side in the paper discharging direction to the printing unit 1 side, the continuously discharged printed paper a is temporarily received.

As an embodiment of the present invention, as shown in FIG.
One end of a long sheet-like or scattered ribbon-like paper receiving member is fixed to the fixing part, and the other end is supported on a roll core part 11 that can be wound and unwound. The parts are fixedly attached to the frames on both sides of the printing and paper discharging part 2. A movable body 12 that can move forward and backward in the horizontal direction along the lower side of the delivery chain 4 in the horizontal sheet discharge section A is interposed between the fixed section 10 and the roll core section 11. The movable body is in the form of a freely rotating roller, and by moving the movable body 12 forward or backward, the paper receiving member is temporarily stretched horizontally on the horizontal paper discharge section A, or is placed on the outside of the horizontal paper discharge section A. It is a setback. FIG. 2 is a perspective view illustrating the outline of the structure of an embodiment of the temporary paper receiving device of the present invention;
The freely rotating roller as the movable body 12 has shaft portions 20 at both ends thereof fixedly attached to a pair of left and right endless chains 15, and the front ends of the endless chains 15 are connected to a pair of sprockets 16 and 16, respectively. It is supported by winding. Of these, a pair of sprockets 16, 16 on the downstream side in the paper discharge direction are each separately attached to frames on both sides of the paper discharge section 2 so as to be rotatably supported. On the other hand, a pair of sprockets 16.16 on the upstream side in the paper ejection direction are coaxially supported by a drive rotation shaft 17, and the rotation shaft is connected to a pulley 18 integrally attached to the outside thereof.
The pulse motor 19 rotates the motor in the forward and reverse directions. By starting the motor 19, the endless chino 15 is moved and the movable body 12 is moved forward or backward. The motor 19, for example, as shown in FIG.
A control unit 25 controls the rotation start timing by cooperating with a timer provided as necessary.
It is started by For example, when you want to start the temporary paper receiving device, turn on the start switch, and when the number sensor 8 detects the passage of the discharged printed paper a that is discharged from the printing unit side by the delivery chain, the timer starts operating. , the time (for example, 0.5 to 1
．． 0 seconds), one motor starts and the moving object 12
moves at a predetermined speed and temporarily moves the paper receiving member to the paper output pile 24.
The member is stretched upward and receives the printed paper a that is continuously discharged onto the member.

The roll core 11 in the device of the present invention may be biased by a spring in the rotational direction for winding up the paper receiving member, but in one embodiment of the present invention, for example, the roll core 11
For installation, a coaxial gear 22 is provided on the sprocket 16 on the side, and a winding and unwinding rotational movement gear 23 of the roll core 11 is meshed with this gear via an intermediate gear 21, so that the rotation circumferential speed of the sprocket 16 is adjusted. The paper receiving member is unwound and wound up in accordance with the moving speed of the moving body 12 by rotating it at a circumferential speed twice that of the moving body 12. Further, the driving operation of the movable body 12 of the apparatus of the present invention can be performed not only by a driving method using a chino but also by an air cylinder.

Next, the operation when using the device of the present invention is shown in Figures 4 and 5.
To explain in detail according to the drawings, first, as shown in FIG.
It is waiting outside the receiving member between 1 and 1. Tagawa 1 paper a is continuously discharged from the printing unit 1 side of the printing machine, and when the discharge pile 24 on the pallet 14 of the loading table 13 reaches a predetermined number of sheets, the pile 24 is moved outward from the paper discharge section 2. In order to set the next pallet 14 for carrying out and forming the next discharged paper pile 24, the start switch of the temporary paper receiving device is turned on. When the number sensor 8 detects the passage of the discharged printed paper a in the order of OFF to ON, the control unit 25 outputs a detection signal, and the timer is activated by the signal, and after the elapse of time, ( As shown in b), the movable body 12 advances horizontally in the direction of the printing unit 1, and the paper receiving member is stretched over the pile 24. (In addition, when the number sensor 8 detects the order from ON to OFF, the control unit 25 does not output a detection signal.)
The more freed printing paper a is stacked on the member.

Then, as shown in (c), the paper receiving member is expanded to a position covering the front and rear ends of the paper discharge pile 24, and the movable body 12 stops. While the discharged printed sheets a are temporarily stacked on the paper receiving member, the lower discharged paper pile 24 is carried out to the outside of the paper discharge section 2 with a pallet by a lifter or the like. Then, place the next pallet 14 on the empty loading platform 13, as shown in Fig. 5 (a).
As shown in FIG. 3, the pallet 14 of the loading platform 13 is raised to a position below the paper receiving member that temporarily receives the paper. Then, when the stop switch of the paper receiving device is immediately set to O or F F, (b) the movable body 12 moves from the lower side of the temporarily stacked printed paper a to the downstream side in the paper discharge direction, and the printed paper a is moved from the edge The parts are sequentially loaded onto the pallet 14, and the parts are automatically wound up into the roll core 11. As shown in (c), the movable body 12 returns to its original position, and the printing paper a is placed on the pallet 14. It can be transferred to.

(Function of the Invention) The device of the present invention stretches a member such as a roll-up long sheet from the operation side of the front part of the paper discharge section 2 toward the printing unit 2, and the printing paper discharge speed On the other hand, the paper receiver can be loaded and unloaded at approximately half the moving speed of the movable body 12, eliminating the fear of the printing operator when loading and unloading the paper tray. can be done with peace of mind.

Furthermore, when the movable body 12 is put in and taken out, one end of the sheet member is fixed by the fixing part 10, so there is no movement of the sheet member itself relative to the discharged printed paper a, so the printed paper There is no rubbing phenomenon between the material and the material, and there is no damage to the printed paper or printed surface image.

(Effects of the Invention) The device of the present invention can be shifted at a relatively low speed as a temporary paper receiving device for continuous paper ejection during preparations such as carrying out a paper pile in a printing machine paper delivery section and mounting the next pallet. Furthermore, the interlocking operation that matches the ejection timing of the ejected printed paper allows for stable operation and is extremely effective in reducing the labor of temporary paper receiving work. .
