Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a paper feeding device used in a paper folding device, particularly a paper folding device composed of a knife and a folding roller.

(Prior Art) It is well known that a paper folding device is composed of a knife that moves up and down and a pair of rotating folding rollers. According to this method, a knife descends to push the paper between the double-folding rollers when the paper is sent above the folding rollers, and the pushed paper is bitten by the double-folding rollers and continues downwards. be discharged. During this process, the paper becomes folded in half.

By the way, in a paper folding device having such a structure, the knife and the folding roller are usually set at fixed positions. Therefore, if the paper being fed is offset in a direction perpendicular to the axis of the folding roller, the folding position of the paper will naturally change. Therefore, in order to set the paper folding position to the desired position, it is necessary to set a reference line parallel to the axis of the folding roller and feed the paper so that one side edge follows this reference line. becomes.

Therefore, conventionally, when attempting to fold paper at a desired position, first set the paper at the approximate position on the reference plate that defines the reference line, then test feed the paper to ensure that the desired folding position is correctly placed directly under the knife. Repeatedly correct the position of the reference plate to reach the
After completing setting the position of the reference plate, determine the position where one side edge of the paper will be fed along the reference plate set as described above, stack the paper at this position, and then start feeding the paper. I was doing it.

As can be understood from the above explanation, prior to the start of paper folding using this type of paper folding device, setting the paper position for paper feeding requires various settings and corrections, which is extremely troublesome. There is an inconvenience in that a certain amount of intuition is required to properly perform this setting.

(Problems to be solved by the invention) This invention aims to simplify the setting of the position of paper relative to a reference plate when folding by a paper folding device composed of a knife and a folding roller. purpose.

(Means for solving the problem) In this invention, a reference mark that moves integrally with the reference plate that also serves as a guide plate is provided on an extension line of the reference plate, and a A feature is that a folding position mark is provided to indicate the position at which the knife is folded.

(Function) Move the paper stack in the direction perpendicular to the axis of the folding rollers, that is, by the paper transport device, so that the fold line on which the paper stacked on the paper stack is to be folded with a knife matches the folding position mark. and move it in a direction perpendicular to the direction in which it is conveyed. Next, the reference plate is moved in a direction perpendicular to the direction of transport by the paper transport device, similar to the paper mounting table, so that the reference mark coincides with one side edge of the paper. The paper is fed so that one side edge of the paper is always aligned with the reference plate. Therefore, when the paper on the paper tray is fed, the paper is folded along a predetermined folding line by a knife and a folding roller.

(Example) An example of this invention will be explained with the help of diagrams: 1
2 is a knife that moves up and down, and 2 is a pair of rotating folding rollers. When the paper is sent above the folding rollers, the knife descends and pushes the paper between the folding rollers 2. This causes the paper to be folded in half and discharged downward. Such a paper folding operation is not particularly different from a normal paper folding device of this type.

3 is a base frame, 4 is a sink, and the fixed sink portion 5 fixed to the base frame 3 intersects with the direction of conveyance by the paper conveyance device, which will be described later. It is constituted by a movable sink part 6 that can freely enter in any direction. 7 is a knob for moving the movable sink part 6 back and forth. 8
is a reference plate integrated with the movable sink section 6, which also serves as a guide plate for guiding the transfer of fed paper. Therefore, this reference plate 8 is L-shaped as shown in the figure, and one side edge of the paper is in contact with this upright wall 8A.

Reference numeral 9 denotes a paper conveying device, which in the illustrated example is composed of a belt 10 that travels straight and a belt 11 that travels obliquely. When the paper on both belts 10 and 11 is transferred, the paper is sent to the side where the reference plate 8 is located by the obliquely running belt 11. And this reference plate 8
The side edge of the paper is brought into contact with the upright wall 8A, and the paper is transported in this state of contact. Note that in actuality, in order to ensure this conveyance, the obliquely running belt 11 is
It is a good idea to place several pressure balls on top of the paper.

Reference numeral 12 denotes a paper mounting table, on which the paper A is stacked. This paper mounting table 12 is placed on a lifting table 13, and is movable in the front and back direction using a knob 14. Further, the lifting platform 13 can be raised and lowered by a suitable drive source via a chain 15, for example. Reference numeral 16 denotes a paper feeding section, which is rotatable by a shaft 17, and sucks paper by vacuum suction force acting on a large number of fine holes around the feeding section.
Pour it onto the sink 4.

The above configuration is not particularly different from this type of device. According to this idea, a reference mark 18 is provided at a position where the reference plate 8, particularly the side edge of the paper, always passes, that is, on the extension line of the upright wall 8A (actually, it is slightly deviated from this extension line).
This reference mark 18 is adapted to move together with the reference plate 8. To this end, in the illustrated example, a display plate 20 is attached to the reference plate 8 via an integral connecting plate 19, and the reference mark 18 is displayed on this display plate 20.

This reference mark 18 is located on the front plate 21 of the paper mounting table 12.
Specifically, the reference mark 18 of the display board 20 can be seen through a window 23 formed on the surface of a guide plate 22 that guides paper feeding.

Further, on the front contact plate 21 of the paper mounting table 12, there is a location corresponding to the extension line of the folding position by the knife 1 and the folding roller 2 (actually, the location is slightly deviated from the extension line).
A folding position mark 24 is displayed on the screen.

In the above configuration, in order to set the position of the paper, first place the paper on the paper mounting table 12 so that the fold line M that is about to be folded matches the folding position mark 24. The knob 14 is used to move the paper in a direction perpendicular to the paper feeding direction by the paper transport device 9. After aligning the folding line M with the folding position mark 24, next turn the knob 7 to move the movable flow section 6, and therefore the reference plate 8, in a direction perpendicular to the paper feeding direction by the paper conveying device 9. , align the reference mark 18 with the side edge of the paper A previously set. With the above steps, preparation for paper feeding is completed.

All that is left to do is to start feeding paper by the paper feed section 16, and the paper fed by the paper feed section 16 is pressed against the upright wall 8A by the belt 11 on the sink 4 of the paper conveying device 9. being transported while Then, the paper is sent directly onto the folding roller 2, where the paper is folded in half by the descent of the knife 1. Needless to say, the folding position at this time coincides with the folding line M set at the beginning.

As mentioned above, the paper is conveyed diagonally on the sink 4 by the belt 11 until it comes into contact with the upright wall 8A. 24 must be offset from the folding position by the knife 1. Mark 18 is also offset to the same extent.

In addition, in the configuration shown in the figure, paper is sent directly from the sink 4 to a paper folding device using a knife 1 and a folding roller 2, but during this time, other paper folding devices, such as paper sent into the gap, collide. A folding device consisting of a buckle with a stopper may also be provided. In a paper folding device having such a structure, the folding position is determined by the position of the stopper against which the leading edge of the paper hits, and the side edges of the paper do not move at all. Therefore, even if this type of paper folding device is present, the paper set position using each mark 18, 24 will not be changed in any way.

(Effects of the invention) As detailed above, according to this invention, the paper on the paper table can be set so that the line to be folded matches the folding position mark, and the line to be folded matches the side edge of the paper. You can now set the position of the paper just by setting the reference mark so that
The effect is that the necessary operations for this are extremely simple compared to the conventional method.
