Description

[Detailed description of the invention] The present invention relates to a paper folding device, and more specifically, to this type of device that can set a large number of sheets of paper at once, has excellent operability, and is easy to systemize with other devices. .

A conventional and very common type of paper folding device, which is the object of the present invention, is shown schematically in FIGS. 1 and 2 of the accompanying drawings.

In both figures, the same reference numerals are given to the same members, and in the figures, 10 indicates a paper feeding mechanism, 20 indicates a paper folding mechanism, and 30 indicates a delivery mechanism.

The details of these conventional devices are not mentioned here because they overlap with the explanation of FIG. 3, which shows an embodiment of the device of the present invention, in which the same members are given the same reference numerals as in FIGS. 1 and 2. The outline is as follows.

First, in the apparatus shown in FIG.
The paper is sent to the paper folding mechanism 20 located on the right side of the figure,
After being folded into a predetermined shape, the sheet is sent to the unloading mechanism 30 located below the sheet feeding mechanism 10, and is discharged out of the system in the direction of arrow A in the figure.

In the apparatus shown in FIG. 2, the paper P is fed by the paper feed mechanism 10.
The paper is sent to the paper folding mechanism 20 located vertically in the center of the figure, and after being folded into a predetermined shape, it is sent to the carrying out mechanism 30 located on the right side of the figure, and in the direction of arrow A in the figure. It is discharged out of the system.

However, both of these types of devices have the following drawbacks due to the arrangement of the components from paper introduction to paper ejection.

(1) Since the components of the paper folding mechanism 20 or the delivery mechanism 30 and the adjustment space are located below the paper feeding mechanism 10, the vertical movement range of the paper feeding table 110 of the paper feeding mechanism 10 is limited, and the paper feeding mechanism 10 is A large number of sheets of paper cannot be loaded on the stand 11 at once.

(11) The adjustment operation members of the paper folding mechanism 20 or the unloading mechanism 30, the paper jam repair area, etc. are not only far away from the operator's hand but also spaced apart from each other, resulting in poor operability.

G11) Since the conveyance direction of the paper during processing within the device system and ejection outside the system greatly changes with respect to the direction in which the paper is introduced, it is difficult to systemize with other devices.

The present invention was developed to solve the problems of the prior art described above, and is a device of this type that can set a large number of sheets of paper at one time, has excellent operability, and is easy to systemize with other devices. The purpose is to provide

In order to achieve this, the present invention uses a paper folding mechanism that includes a paper feeding mechanism, a paper folding mechanism that folds the paper sent from the paper feeding mechanism, and a discharge mechanism that discharges the folded paper out of the system. In the apparatus, a paper feed opening lower plate that is adjacent to the paper feeding mechanism and that guides the paper to be fed to the paper folding mechanism is bent upward at a substantially right angle to the initial paper feeding direction of the paper feeding mechanism; A subsequent paper folding mechanism is disposed above the paper feeding mechanism, and an ejecting mechanism is disposed in front of the paper feeding mechanism and below the paper folding mechanism in the initial paper feeding direction, so that the paper after folding is is discharged out of the system in substantially the same direction as the initial paper feeding direction.

The present invention will be described in detail below with reference to FIG. 3 of the accompanying drawings.

As mentioned above, in this figure, all reference numbers that are the same as those in FIGS. 1 and 2 are approximately the same as the members in these figures.
Indicates the member that plays the role of

The paper feeding mechanism 10 includes a paper feeding tray 11 having a lifting force, and the paper P is loaded on this tray.

The paper P comes into contact with the paper feed ring 12 in a biased state due to the uplifting force of the paper feed table 11, and is reliably separated one sheet from above and fed by the unidirectional rotational movement of the paper feed ring 12. .

The separated paper P is placed on the paper feed opening lower plate 1 which is curved upward.
3, the moving direction changes upward at a substantially right angle to the initial paper feeding direction, and enters the gap between the paper feed port lower plate 13 and the paper feed port upper plate 14.

When the leading edge of the paper P that has entered the gap reaches the tangent between the drive roller 21 and the driven roller 22 of the paper folding mechanism 20 located diagonally above the paper feed mechanism 10, the paper P is transported by both of the rollers. It will be taken over on 21st and 22nd.

In this embodiment, the paper folding mechanism 20 is provided with two folding plates 25 and 28 so as to be able to fold twice, and when setting it to fold once, a guide provided on the first folding plate 250 is used. Board 27
As a result, the passage 25t on the folding plate 25 side is closed.

When the guide plate 27 is in the retracted position (not shown) and the paper folding mechanism 20 is in a state where it can fold twice, both the rollers 2
The paper P taken over by the first folding plate 250 first enters the passage 25 of the first folding plate 250 until its leading end abuts against the stopper 26.

However, even after the above-mentioned contact, the trailing edge of the paper P is forcibly fed into the passage 25 by both rollers 21 and 22, so the trailing edge of the paper P is separated by the drive roller 21 and the driven roller 23. Deflect towards the tangent.

Therefore, this bent portion is held between both rollers 21 and 23 to form a first fold, and the paper P is held between both rollers 21 and 23.
, 23<, and are transported toward the passage 28t of the second folding plate 28.

Also on the folding plate 28, the leading edge of the paper P is at the stopper 2.
9 into the passageway 28 until it comes into contact with it.

Similarly to the above, the rear end side of the paper P is connected to both rollers 21 and 23.
Since the roller is forcibly fed into the passage 28 and broken, the rear end side is bent toward the tangent line between the drive roller 21 and the driven roller 24.

Therefore, this bent portion is held between both rollers 21 and 24 to form a second fold, and the paper P is held between both rollers 21 and 24.
24, the paper is sent out toward the delivery mechanism 30 located below the paper cutting mechanism 20.

Contrary to the above, the guide plate 27 is in the closed position (position shown)
, and when the paper folding mechanism 20 is in the state of folding once, the paper P taken over by both rollers 21 and 22 advances directly toward the tangent between the driving roller 21 and the driven roller 23 according to the guide plate 27. do.

Then, in the manner described above, the first fold is formed after being fed into the passage 28 of the folding plate 28, and both rollers 21.24
It is sent out toward the delivery mechanism 30 by.

The folded paper P sent to the delivery mechanism 30 changes its traveling direction according to the guide plate 31, and is transported by the conveyor 32.
The paper is discharged out of the system in the direction of arrow A, which is approximately the same direction as the initial paper feeding direction.

The stoppers 26 and 29 of the folding plates 25 and 28 are both movable in the direction in which the paper P enters.
．． The setting position is indicated on 28.

That is, by aligning the stoppers 26 and 29 with arbitrary indicators, the apparatus can be adjusted according to the size, folding strength, etc. of the paper P.

According to the device of the present invention having the above configuration, the following effects can be obtained.

First, as mentioned above, the stoppers 26.2 of the folding plates 25, 28
The setting position of 9 may be the same as usual depending on the size of the paper P, folding strength, etc., and must be adjusted each time according to the conditions.

Further, it is necessary to make fine adjustments depending on the processing speed, stiffness of the paper, etc., and the adjustment operation is extremely troublesome.

According to the device of the present invention, these operations can be performed in a comfortable posture and within a range that is easily visible, so that the operations can be performed reliably in a short period of time.

Even if a deep paper jam occurs, it can be easily confirmed because the paper transport range is in a visible position, and since there is sufficient space for removing the paper jam in each section, it is easy to remove the paper jam. It can be done smoothly.

Further, since there are no structural members of other machine tanks, adjustment spaces, etc. below the paper feed tray 11, the range of vertical movement of the paper feed tray 11 can be increased, and a large amount of material can be stored on the paper feed tray 11. It can be modified so that several sheets of paper P can be loaded at once.

Moreover, since there is little change in the conveyance direction of the paper during processing within the system and discharge from the system, it is easy to systemize with other devices.

As described in detail above, the paper folding device of the present invention satisfies the intended purpose and has many practical benefits.
