Description

[Detailed Description of the Invention] The present invention relates to a paper feed guide, and particularly to a paper feed guide suitable for application to a spine pasting machine.

When making a set of multiple sheets of paper, including regular paper or carbon paper for copying, into one booklet, attach a spine sticker to the back of each temporarily attached booklet. Conventionally, in spine pasting machines that perform mounting, the guide that guides booklets to the paper feed table has a guide plate installed on the booklet spine pasting side of the booklet loading table on which the booklets are stacked. The back side is in contact with the above-mentioned guide plate, and the side surface is in contact with the side of the paper feed table, and the booklets are sequentially sent out to the paper feed table by the pushing body along this guide plate, starting from the topmost booklet. being done.

However, when the booklets are stacked on the booklet placement table or when the booklets are sent to the paper feed table by the pushing body, the booklets may become separated from the guide plate or may be tilted. If the booklet is not fed to the paper feed table immediately along the guide plate, the belt installed on the top of the paper feed table and used to feed the booklet will not be able to feed the booklet smoothly, and the spine paper will not be fed smoothly. It has the disadvantage that it does not adhere well.

The present invention was developed in view of this, and includes a booklet placing table on the front end of the paper feeding table for stacking and placing booklets. A holder that is parallel to the front end surface of the paper feed table and is swingable in the vertical direction on the paper feed table surface of the paper feed device including a guide plate having a height higher than both tables near the booklet table. a retaining block having a rod;
A bracket fixed by a fixing screw is fitted into the holding rod, a second bracket fixed by a fixing screw is fitted into the holding rod, and an end of the bracket near the guide plate is fitted with a second bracket fixed by a fixing screw.
A holding plate is attached parallel to the guide plate, and the second bracket has a shaft extending downward, and a cylindrical roller is rotatably mounted on this shaft, and a part of the roller protrudes toward the guide plate side by the holding plate. Each time the booklet loading table rises, the upper booklet is brought into contact with the guide plate by the presser plate, and furthermore, when the booklet is sent out to the paper feed table by the pushing body, the booklet is brought into contact with the guide plate by the rollers. It is an object of the present invention to provide a paper feed guide that can be pressed against the paper feed guide so that the paper feed guide can be reliably aligned with the guide plate.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the paper feed guide according to the present invention, which is provided at the front end of the paper feed table 1, and is capable of stacking booklets and is movable up and down. A guide plate 3 is provided at one end of the paper feeding table 2 and partially extends over the paper feeding table 1 side end, and this guide plate is higher than both the tables 1 and 2. A rectangular parallelepiped holding block 4 is provided on the upper surface of the paper feed table 1 near the booklet loading table 2 and at the end on the opposite side from the guide plate 3.
A holding rod 5 parallel to the front end surface of the paper feed table 1 is swingably supported above the holding block 4 by a pivot 6 attached to the end of the holding rod 5. . This holding rod 5 has a fixing screw 7.
A second bracket 8 fixed with a fixing screw 9 is inserted into the bracket 8.
A bracket 10 is inserted. A holding plate 11 parallel to the guide plate 3 is attached to the end face of the bracket 7 closer to the guide plate 3, and a second bracket 10
has a shaft 12 extending downwardly, the shaft 1
2, a cylindrical roller 13 is rotatable, and a part of its circumference is closer to the guide plate 3 than the presser plate 11.
It is provided so as to protrude to the side. Furthermore, a claw 14 as shown in the figure is provided below the portion of the presser plate 11 that touches the booklet placement table 2.

In this embodiment, depending on the thickness, paper quality, and size of the booklet P, the fixing screw 7 is loosened and the presser plate 11 is
Move the bracket 8 attached to the roller 13 to a predetermined position, tighten and fix the fixing screw 7, loosen the fixing screw 9, move the second bracket 10, and fix the roller 13.
After adjusting the amount of protrusion, tighten and fix.

The booklets P are stacked on the booklet placement table 2, and are sent out in the direction of arrow (A) by a pushing body (not shown), and the booklet placement table 2 is automatically raised to continuously load the booklets P. It is made to send out.
Here, when the booklet placement table 2 is raised, the booklet P is brought into contact with the guide plate by the presser plate 11,
This can be done smoothly using the claws 14.

Thereafter, when the booklet P is sent out by the pushing body, it is pressed even more strongly by the rollers 13. At this time, the booklet P may warp, but since the back surface of the booklet P is along the guide plate 3, it is possible to perform good back sticking.

Furthermore, even if the booklet placement table 2 is raised to be at the same height as the paper feed table 1, the holding rod 5 rotates upwards, so the paper feed guide will not be damaged, and furthermore, the booklet placement table 2 can be manually removed. When feeding P, if the holding rod 5 is raised by rotating it, it will not interfere with the work.

The paper feed guide of the present invention can be applied not only to spine pasting machines but also to automatic wire binding machines, file paper punching machines, and other devices that require paper feeding in units of one book.

As described above, the present invention has a booklet placing table on the front end of the paper feeding table on which booklets are piled up, and a part of the booklet placing table is attached to one end of the booklet placing table. A holding rod that is parallel to the front end surface of the paper feed table and is movable in the vertical direction is provided on the paper feed table surface of the paper feed device, which is provided with a guide plate having a height higher than both tables, near the booklet placing table. A holding block is provided, a bracket fixed by a fixing screw is fitted into the holding rod, a second bracket fixed by a fixing screw is fitted into the bracket, and a second bracket fixed by the fixing screw is fitted, and the bracket is positioned near the guide plate. A holding plate is attached to the end in parallel with the guide plate, and the second bracket has a shaft extending downward, and a cylindrical roller is rotatably attached to this shaft, and a portion of the second bracket is attached to the guide plate from the holding plate. The upper booklet is brought into contact with the guide plate by the holding plate each time the booklet table is raised, and when the booklet is sent out to the paper feed table by the pushing body, the roller Since it is pressed against the guide plate, the back side of the booklet can be reliably aligned with the guide plate.
Good backing can be achieved.

In addition, since the holding rod is swingable, damage can be prevented when excessive force is applied from the booklet or the booklet mounting table.Moreover, by rotating the holding rod upward, This has the effect of improving workability during manual paper feeding.
