Description

[Detailed description of the invention] Industrial application field This invention is a paper-aligning machine that aligns the two sides of a large number of stacked sheets of paper used for printing, bookbinding, etc. This is a device that can automatically feed a large number of sheets of paper that have undergone this air removal into a cutting machine without the need for human intervention, and is used in the bookbinding industry, printing industry, etc. It is something that can be done.

Conventional technology Conventionally, in order to align the two sides of a large number of stacked sheets of paper used for printing, bookbinding, etc., a paper alignment machine is used to reduce the contact resistance between the stacked papers. Previously, air was introduced into the spaces between stacked papers by squeezing them. However, even after the paper alignment is completed, if air exists between the stacked papers, the resistance between the stacked papers will decrease, so when sending the aligned paper to the next process, such as a cutting machine,
Misalignment of stacked papers is likely to occur. Conventionally, in order to remove the air between the stacked sheets of paper with the two sides aligned, this was done by pressing and sliding a human arm against the top surface of the paper. Since this method relies on manual labor, it not only requires insufficient force to ensure air removal, but also requires skill and imposes a heavy physical burden on the operator.

Furthermore, if the stacked paper is manually pressed and fed when it is transferred to a cutting machine after the air removal process is completed, it has the disadvantage that the stacked paper is likely to be misaligned.

Problems to be Solved by the Invention The present invention eliminates the above-mentioned drawbacks, and uses sufficient force to reliably remove air from between the stacked sheets of paper arranged by a paper alignment machine. One of the purposes is to not only bleed the air, but also to bleed the air without requiring any skill or the like to perform the work, and without putting any physical burden on the worker. Another purpose is to transfer the paper to the cutting machine after completing air removal.
This eliminates the need to press and move the paper manually, and prevents the stacked papers from shifting.

Means for Solving the Problems In order to solve the above problems, the present invention has the following features:
A flat U-shaped guide frame located facing the top surface of the paper loading table of a paper alignment machine equipped with an appropriate paper alignment mechanism,
A support shaft is mounted on the upper surface of a support installed vertically on the paper alignment machine so that it can rotate freely in the vertical direction, and a chain that is connected to a motor that rotates in forward and reverse directions and operates back and forth is installed on the parallel support rods of this guide frame. This constitutes a back-and-forth movement mechanism, and the press arm is connected to the back-and-forth movement mechanism of the guide frame, so that the press arm can move back and forth while facing the paper table according to the support rod of the guide frame, and the paper of the press arm can be moved back and forth. A pressure roller that presses the paper on the paper stack and removes air is connected to the paper stack side, and the paper is placed on the paper stack by facing the paper stack in one of the forward and backward movement directions of this pressure roller. In addition to forming a fixing bar for pressing and fixing, a feeding arm is positioned on the side of the paper loading table parallel to the back and forth movement direction of the pressure roller, with the paper surface facing, and this feeding arm is parallel to the paper feeding direction. It is supported so as to be movable back and forth on a provided guide rail, and is movable back and forth on the paper table by a back and forth movement feeding mechanism provided on the guide rail.

Operation In the device configured as described above, first, an appropriate number of sheets are stacked and placed on the paper mounting table of the paper sorting machine,
After aligning the two sides of this stacked paper using an appropriate paper alignment mechanism, a vertically movable guide frame positioned facing the paper mounting table of the paper alignment machine is rotated about the support shaft. By operating the chain of the forward and backward movement mechanism provided on this guide frame, the press roller connected to the lower end of the press arm can move the press roller connected to the lower end of the paper. Move back and forth while pressing the paper fixed on the table with a fixed bar,
Air can be removed by pushing out the air that has accumulated between the stacked sheets of paper.

In addition, after this air removal is completed, if the forward/backward movement feeding mechanism is activated and the feeding arm is moved in the paper direction according to the guide rail installed parallel to the paper feeding direction, the paper surface of the feeding arm will be placed on the paper. The paper on the table can be pressed and moved toward the cutting machine, and the aligned paper can be moved to the cutting machine without being misaligned.

An engaging roller 25 is rotatably fixed to the pressing arm 21 in contact with the upper surface of the lower wall 23 of the guide frame 8 and at a position on the lower surface of the upper wall 24 of the guide frame 8.
5 is abutted against the lower surface of the upper wall 24. Further, a press roller 27 of a constant weight is rotatably connected to the lower end of the press arm 21 for pressing the stacked papers 26 on the paper table 6 and removing air. Also, in order to prevent the paper 26 from shifting when pressed by the pressure roller 27, one end of the paper 26 is placed on the paper mounting table 6.
A fixing bar 28 is fixed to a fixing cylinder 30, and this fixing cylinder 30 is pivotally supported on a paper mounting table 6 by a fixing shaft 31, and a supporting body 9
A tilting cylinder 32 with one end supported by a shaft is connected to the side surface of the fixed cylinder 30 so that the fixed cylinder 30 can be tilted about the fixed shaft 31 as a fulcrum.

Further, the paper surface 34 is placed above the side surface 33 on the short side of the paper mounting table 6, which intersects with the side surface of the paper mounting table 6 on which the guide frame 8 is provided and is parallel to the front-rear movement direction of the pressing roller 27. A feed arm 35 is positioned and supported by a guide rail 36 provided parallel to the paper feeding direction so as to be movable back and forth. This guide rail 36 fixes the guide main body 37 to the substrate 4 on the lower surface of the paper mounting table 6 facing the side where the guide frame 8 is attached, and also connects the feed arm 35 to the ball bearing 38.
It is slidably fixed through the. This guide rail 36 has a forward and backward moving mechanism 40 for the feed arm 35.
The forward and backward moving feed mechanism 40 of this guide rail 36 is formed by a feeding electric motor 4 that rotates in forward and reverse directions.
1 is composed of a chain 43 that moves back and forth and is connected via a sprocket wheel 42. By fixing the feed arm 35 to this chain 43, the paper surface 34 can be moved back and forth on the paper placement table 6. It is possible to move.

In the device configured as described above, first, an appropriate number of sheets of paper 26 are stacked on the paper mounting table 6 of the paper sorting machine 1, and the stacked sheets of paper 26 are squeezed to create air between the sheets of paper 26. After inserting the paper 26, the two sides of the paper 26 are aligned by an appropriate paper alignment mechanism (not shown), and then
The fixed cylinder 3 is activated by operating the tilting cylinder 32.
After the paper 26 is placed in an upright position, the fixed cylinder 30 is operated and the fixed bar 28 presses and fixes the paper 26 onto the paper mounting table 6 in a stable manner. Next, the paper mounting table 6
The vertical movement cylinder 11 is operated to position the guide frame 8 facing the paper 26 so that the guide frame 8 is positioned substantially parallel to the surface of the paper 26, the pressure roller 27 is positioned at one end of the upper surface of the paper 26, and the electric motor 16 is rotated in the normal direction. When activated, the chain 15 provided on the guide frame 8 rotates in the normal direction and moves the pressing arm 21 forward, so that the pressing roller 27 connected to the lower end of the pressing arm 21 moves the paper 26 on the paper mounting table 6. Move forward while pressing with your own weight,

is reversed, and the chain 15 is operated in the reverse direction, so that the press roller 27 also retreats from the surface of the paper 26 and when it returns to its original position, one end of the press arm 21 presses the micro switch 46, causing the electric motor 16 to operate. At the same time, the vertical movement cylinder 11 is activated to raise the guide frame 8. As the guide frame 8 rises, the pressing arm 21 also engages the rollers 22 and the engaging rollers 25 with the lower wall 23 and the upper wall 24 of the guide frame 8, and rises together with the pressing roller 27. Next, the fixed cylinder 30 is actuated, and the fixed bar 28
If the pressure fixation to the paper 26 is released and the fixed cylinder 30 is tilted with the tilt cylinder 32,
This allows the stacked papers 26 to be transferred to the next process.

Next, by rotating the feeding electric motor 41 in the normal direction and operating the chain 43 via the sprocket wheel 42, the feeding arm 35 is moved along the guide rail 36, and the paper is pressed by the paper contact surface 34. The paper 26 is moved and inserted into the cutting machine 44. The positional relationship between the cutting machine 44 and the paper aligning machine 1 may vary depending on the purpose of operation, but after performing the paper aligning operation at the position shown by the one-dot chain line in FIG. , the paper aligning machine 1 is moved along the moving rail 45 to the position shown by the solid line. Next, remove the air,

is fixed to the board 4, but in other different embodiments, the guide rail 36 is installed in order to reduce the weight of the board 4 and improve the operability of the board 4 during paper alignment work.
may be fixedly formed on the base 2 and moved back and forth.

Effects of the invention Since the invention is constructed as described above,
When removing air from between sheets of paper aligned with a paper alignment machine, not only can air be removed reliably with sufficient force, but the air removal process does not require hot kneading, and it is easy for the operator to remove air. , it is possible to remove air from stacked papers without any physical strain. After this air removal is completed, operate the forward and backward movement feeding mechanism and move the feeding arm in the direction of the paper along the guide rail, and the paper will press the paper on the paper loading table and move in the direction of the cutting machine. This makes it possible to move the aligned paper to the cutting machine without causing any misalignment, as would be the case when pressing and moving the paper manually.
