Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anti-blocking device for preventing printed paper from sticking or adhering before or after printing.

Stacks of printed paper often cause the sheets to stick together and become an obstacle in various operations requiring the sheets to be separated from one another.

The present invention has been made to solve the above problems, and provides a printing paper blocking prevention device which can provide an extremely efficient blocking prevention effect. A detailed description will be given below with reference to the drawings showing the embodiment.

The device of the present invention consists of a fixed table 1, a rotating table 2, a rotating roller 3 provided at the boundary between the two tables 1 and 2, a first clamping means 4 for clamping the printing paper on the fixed table 1, and printing on the rotating table. It consists of a second clamping means 5 that clamps paper and turns together with the turning table 2, a movable printing paper ironing roller 6 provided between the first clamping means and the second clamping means, and a rotary roller driving means, and the turning table 2 rotates with the rotation of the rotating roller 3.

1 to 3 show an embodiment of the present invention,
The table 1 and the rotating roller 3 are supported by an appropriately shaped frame (not shown). The first clamp means 4 and the second clamp means 5 have air cylinders operated by pneumatic pressure, and the first clamp means 4 is supported by a clamp means support arm (not shown) attached to the frame. 2
The clamping means 5 is provided on an arm (not shown) fixed to the rotating shaft of the rotating roller 3 in order to make a turning movement with the rotation of the rotating roller 3.

The rotating table 2 rotates along with the rotation of the rotating roller 3, so that the rotating table 2 rotates around the rotating shaft 3 of the rotating roller 3.
It is supported and fixed by an arm 7 fixed to a.

There is a gap between the fixed table 1 and the rotating table 2, and a rotating roller 3 is provided below the gap so that the top of the rotating roller 3 substantially coincides with the extension of the upper surface of the fixed table 1.

In addition, in the state shown in Fig. 1, the fixed table 1
In order to reduce the distance between the fixed table 1 and the rotating table 2, it is desirable that the end surfaces of the fixed table 1 and the rotating table 2 facing the rotating roller 3 have an arcuate shape along the circumference of the rotating roller 3. As a result, the printing paper can slide more smoothly. However, its upper edge must not be sharp. It should form a small radius.

The rotating roller 3 is rotated by a motor (not shown) capable of forward and reverse rotation, and the amount of rotation thereof can be controlled by a limit switch, a timer, or the like.

Furthermore, the fixed table 1 and the rotating table 2 can be replaced with air tables to make the printing paper slide more smoothly.

Next, the blocking prevention process for the printing paper P shown in FIGS. 1 to 3 will be briefly described.

B. As shown in FIG.
is activated to press and clamp one end (the right end in the drawing) of the printing paper P to the revolving table 2.

(b) Rotate the rotary roller 3 clockwise by 90 degrees from the state of (a) above using the driving means. As a result, the arm 7, the rotating table 2, the second clamping means 5, etc. simultaneously rotate, resulting in the state shown in FIG. 1 to the right, and a deviation of l ₁ occurs between the bottom layer and the top layer of printing paper.

C. Next, after the left end of the printing paper P is clamped to the fixed table 1 by the first clamping means 4,
Then, the rotary roller 3 is rotated counterclockwise while the second clamping means 5 remains in the clamped state. As a result, the printing paper P forms a raised mountain 9. An air layer is formed between each of the printed sheets in the 9 portions of the ridges, so that the sheets are completely separated.

D. Next, the pile 9 of printed paper is moved between the first clamping means 4 and the second clamping means 5 by the printing paper ironing roller 6. At this time, air may be blown in from the side of the mountain. After moving the mountain 9 to the left side, it returns to the right side, and the second clamping means 5 is released, and the printing paper below the second clamping means 5 is also caused to shift, so that the entire printing paper P is covered with a shift or an air layer. can be produced and an anti-blocking effect can be obtained.

4 to 6 show another embodiment, in which the turning table 2 is constituted by a bendable sheet whose tip is fixed to a rotating roller 3. FIG. Further, in order to prevent the printing paper P from slipping down during the process from the state shown in FIG. 1 to the state shown in FIG. 2, the printing paper P may be supported by an auxiliary clamp 8. Other points are the same as the embodiment shown in FIGS. 1 to 3.
