Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to a paper sheet straightening and folding device, and is particularly a device applied to printing paper straightening and folding.

[Prior art]

If the printing paper is curled, proper paper feeding and registration may not be possible. In particular, when printing is performed by multiple passes, the printing paper tends to become curly and curl each time it is printed. Conventionally, in order to remove this curl, a printing operator or an auxiliary worker folded the printing paper diagonally little by little and pounded it by hand. Such manual straightening increases the cost of printing operations, and the results are unsatisfactory.

[Problem that the invention attempts to solve]

SUMMARY OF THE INVENTION The object of the present invention is to provide an automatic straightening and folding device for printed paper which has a simple structure and is highly workable, as an alternative to the conventional manual method for straightening printed paper.

[Means to solve the problem]

Using a table, a flexible belt or string (hereinafter referred to as flexible strip), and a press means, the printed paper placed on the table is bent by the flexible strip, and the press means presses from above the bent part to remove the curl and fold it at the same time. Put in.

[Summary of the idea]

The paper industry straightening and folding device according to the present invention includes a table 1, a flexible strip 2 provided across the table, one end of which is fixed and the other end free, and the flexible strip 2. a frame 4 that suspends the rotating body 3 above the table 1;
The flexible belt winding means 6 comprises a drive unit 12 that runs the flexible belt along the fixed end side of the flexible strip 2, and the pressing means 7 that presses a bent sheet of paper that is suspended above the table 1 and moves vertically and horizontally. ing.

〔Example〕

FIG. 1 is a diagram schematically explaining one example of the device of the present invention. A table 1 is provided with a groove 8 at a diagonal position, and a flexible string 2 fixed at one end is attached to the groove 8. The free end side of the flexible string 2 is connected to a flexible string winding means 6 (shown in an omitted form in the figure) that winds up the flexible string 2 toward the fixed end side. A press means 7 for pressing the bent portion of the bent printing paper 9 is provided above.

FIG. 2 shows a winding means 6 for the flexible string 2, in which the free end of the string 2 is connected to a rotating body 3 rotated by a motor 11 in a block 10 suspended on a frame 4 which can be horizontally rotated through 90 degrees. 1
0 is moved along the frame 4 by a chain 12 as a drive unit. The frame 4 is set parallel to the groove 8 or the flexible string 2.

FIG. 3 is a plan view of the press means 7 viewed from above, and shows a pair of parallel guide frames 13 and a crosspiece 14.
is movably extended in the direction of arrow A via a block 15, and a press means mounting block 17 for supporting the press means 7 is provided on the crosspiece 14 so as to be movable in the direction of arrow B along the crosspiece 14. Crosspiece 14
The movement of the press means mounting block 17 may be achieved by engaging gears and racks rotated by motors, or by connecting a moving body to an endless chain or wire and rotating the chain or wire. good. By adjusting the movement in the A direction and the B direction to appropriate values using the drive mechanism described above, the pressing means 7 can perform a pressing operation while freely moving in vertical and horizontal directions.

When the flexible string 2 shown in FIG. 1, the flexible string winding means 6, and the pressing means 7 complete the work of folding and folding in one direction, the flexible string 2 shown in FIG. Straightening and folding operations with different directions are performed by means of a winding means 6 and a pressing means 7 whose directions are changed with other flexible strings not shown in the drawings.

Figure 4 shows the different directions of the above work.
This is printed paper that has been smoothed and folded.

[Effect of idea]

The device of the present invention can automatically and efficiently remove curls from paper sheets such as printing paper, and can also create folds 16 as shown in Figure 4 at the same time as removing curls, making the printing paper more strained. , accurate paper feeding and registration accuracy can be obtained.

[Brief explanation of the drawing]

Figure 1 is a diagram explaining the mechanism of the device of the present invention, Figure 2
The figure is a partially cutaway view showing an example of the flexible belt or string winding means 6, FIG. 3 is a plan view of the press means 7, and FIG. 4 is a plan view of printed paper processed by the apparatus of the present invention. Among them, 1 is a table, 2 is a flexible belt or flexible string, 3 is a rotating body for winding up the flexible belt or string, 6 is a winding means, and 7 is a pressing means.
