Description

[Detailed Description of the Invention] The present invention relates to an improvement of a paper aligning device in a sheet feeding section of a sheet-fed printing press.

The first paper alignment device in the paper feed section of a conventional sheet-fed printing press
To explain using figures 2 and 3, 1 is a width direction position regulating paper alignment plate, 2 and 2' are front direction position regulation paper alignment plates, 3 is a frame of the printing press, and 4 is a horizontal axis provided between the left and right frames 3. , 5 and 5' are bearings slidably inserted into the horizontal shaft 4, and the width direction position regulating paper alignment plate 1 and the front direction position regulating paper alignment plate 2 adjacent thereto are fixed to the bearing 5, Another front position regulating paper alignment plate 2' is fixed to the bearing 5'.
Further, 6 is a set bolt for fixing the bearing 5 to the horizontal shaft 4, 7 and 11 are pile stands, 8 is a paper pile, 9 is a separator, and 10 is a chain of a pile lifting device. One sheet of paper is fed to the printing section from the top, and the pile table 7 is raised by the chain 10 of the pile lifting device to keep the top surface level of the paper pile 8 almost constant, and the paper pile 8 is moved to the paper alignment board. 1, 2, 2' to hold it in place.

In the paper feed unit paper alignment device of the sheet-fed printing press, when the amount of paper pile 8 decreases, preliminary paper is stacked on the next pile table 11. At this time, the widthwise position regulating paper alignment plate 1 is used to regulate the widthwise position of the paper pile 8 during printing, so if the size of the paper stacked on the pile stand 11 is different from the paper being printed, the Without it, the next paper stacking operation cannot be carried out. For this reason,
When the paper sizes are different, after printing of the paper pile 8 is finished, remove the pile stand 7, adjust the width direction position of the widthwise position regulating paper alignment plate 1, attach the pile stand 11, and stack the next paper. This method has the disadvantage that it requires a lot of work, requires a lot of time for preparation, and reduces productivity.

This proposal addresses the above-mentioned problems by dividing the widthwise position regulating paper aligning plate and the adjacent front position regulating paper aligning plate into upper and lower parts, and also attaching each widthwise position regulating paper aligning plate to the printing machine. This relates to a paper feed unit paper aligning device for a sheet-fed printing press, which is characterized in that it is attached to a member on the frame side of the machine so that its position in the width direction can be adjusted. Even if the size of the paper is different from the size of the paper currently being printed, it is possible to pre-stack the paper to be printed next on the next pile table while printing the paper currently being printed, increasing productivity. An object of the present invention is to provide an improved paper feed unit paper aligning device for a sheet-fed printing press that can improve the performance.

Next, the paper feed unit paper aligning device of the sheet-fed printing press according to the present invention will be explained with reference to an embodiment shown in FIGS. A horizontal shaft 12 has both ends fixed to the left and right frames 3 of the printing press, and a bearing 13 is slidably fitted to the horizontal shaft 12, as shown in FIG. A paper alignment plate 15 for regulating the widthwise position of the paper pile 14 and a paper alignment plate 16 for regulating the forward position of the paper pile 14 are fixed to each other via spacers 17 and 18. Further, as shown in FIG. 5, presser feet 19 and 20 are protruded near both ends of the paper alignment plates 15 and 16, and these presser feet 19 and 20 abut against the presser plates 21 and 22 to hold the paper alignment plates 15 and 16 vertically. are doing. The bearing 13 can be fixed to the shaft 12 with a set bolt 23 having a grip. Also the fourth
24 in the figure is a horizontal shaft whose both ends are fixed to the left and right frames 3 of the printing plate, and the horizontal shaft 24 is the horizontal shaft 1 mentioned above.
2 and parallel to the horizontal axis 12. Further, a bearing 25 is slidably fitted to the horizontal shaft 24.
A paper alignment plate 27 for regulating the position in the width direction of the paper pile 26 and a paper alignment plate 28 for regulating the position in the front direction of the paper pile 26 are fixed to the bearing 25 . Also, as shown in FIG. 5, presser feet 2 are placed near both ends of the paper alignment plates 27 and
9 and 30 are provided in a protruding manner and abut against the holding plates 22 and 31 to hold the paper alignment plates 27 and 28 vertically. The bearing 25 can be fixed to the shaft 24 with a set bolt 32 having a grip. In addition, as shown in FIG.
In order to match the positions of and 27 to the paper size,
Scales 33 and 34 are provided on the shaft 12 and the shaft 24.

Next, the operation of the paper feed unit paper aligning device of the sheet-fed printing press will be explained. Paper pile 1 placed on pile stand 7
As a sheet of paper is fed from the top of the paper stack 4 to the printing section by the separator 9, the pile stand 7 supported by the chain 10 of the pile lifting device rises. ,1
It is held in place by 6 and 2'. When the number of paper piles 14 is running low and you want to stack a paper pile of a different size than the paper being printed on the next pile stand 11, loosen the set bolt 32 with a grip, and adjust the setting bolt 32 in the width direction while looking at the scale 34. After moving the position regulating paper aligning plate 27 to match its left and right dimensions to the paper size, tighten the set bolt 32 to fix the bearing 25 to the shaft 24, and then attach the crosspiece 3 to the pedestal 35.
6 is constructed and the pile stand 11 is placed on it, the sheets can be aligned and the paper stacking preparation is completed. Thereafter, a preliminary paper stacking operation is performed to complete the formation of the paper pile 26. When the printing of the paper pile 14 is completed and there is no more paper on the pile stand 7, the pile stand 7 and the crossbar 37 on which it was placed are removed and supported by the chain 10 of the pile lifting device. The support plate 38 is lowered to the position indicated by the imaginary line 38 and hooked onto a claw 39 provided on the crosspiece 36. Next, loosen the set bolt 23 with a grip, slide the bearing 13, and set the scale 3.
While looking at 3, align the left and right widths of the alignment plate 15 with the paper pile 26.
paper alignment plates 15 and 16.
As shown by imaginary lines 15a and 16a, the pile stand 11 on which the paper pile 26 is placed is moved along the same vertical plane as the paper alignment plates 27 and 28 of the spare paper pile 26 by the pile lifting device.
When the paper pile 26 is raised through the eight chain 10, the paper pile 26 is fed to the printing section by the separator 9 while being regulated by the paper alignment plates 15, 16 and 2'.

With the paper feed unit paper alignment device of conventional sheet-fed printing presses, if the paper width of the next paper to be printed is different from the paper being printed, the next paper must be printed until the paper being printed has finished printing. It is not possible to reserve the paper to be stacked on the pile stand in the paper feed unit, and for this reason, the pile stand cannot be removed or the width direction position regulation paper alignment plate must be removed in the width direction after the paper being printed has finished printing. We were adjusting the position, installing the next pile stand, and stacking the next paper, and it took a lot of time to prepare.
The paper feed unit paper aligning device of the sheet-fed printing press in this case is configured as described above, and even if the size of the paper to be printed next is different from the size of the paper currently being printed, While printing the current paper, the next paper to be printed can be pre-stacked onto the next pile table, which has the effect of improving productivity.
