Abstract

PURPOSE:To pile together paper completely straightened by forming each paper folding roller in its paper folding surface mutually with a predetermined space to be held in a contactless condition. CONSTITUTION:Paper 5, delivered from a delivery roller 8, is fed into a stopper unit 4 through a guide passage 4a by a retaining roller 3 and a paper folding roller 2a, and the paper 5 adapts its point end to a stopper 4b of the stopper unit 4, when a feed of the paper is stopped, the paper, bending its almost central part to the bottom to be held in a space D between each paper folding roller 2a, 2b, is fed to the bottom. Under this condition, the paper 5 is folded by this space D with a fold portion not completely bent, thus in a condition after folding, the paper 5, holding its restoring force, is held in a condition opened in a V-shape immediately even after the folding. The paper 5 in the two-part folded condition thus fed downward removes static electricity by a static eliminator 17, thereafter the paper is piled together in a condition opened to a V-shape on a valley-shaped bottom part 14a of a receiving box 14.

Description

Detailed Description of the Invention: a. Field of Industrial Application The present invention relates to a paper folding machine, and in particular, to prevent stacking errors when folding two sheets of paper in a V-shape folded state. The present invention relates to a novel improvement to enable stacking in good alignment without any complications.

b. Conventional technology Various types of paper folding machines have been adopted for this type of paper folding machine that have been used in the past. Kaisho 61-19
The configuration shown in FIG. 13 of Japanese Patent No. 1358 can be disclosed.

That is, at a position below the passage 1a in the guide body indicated by the reference numeral 1 in FIG. 7, there is a feed 8! Folding rollers 2a and 2b are arranged as a pair so as to rotate in opposite directions.

A presser roller 3 is in contact with the folding roller 2a, and a passage 4a is located adjacent to the folding roller 2b.
A folded body 4 having a folded body 4 is arranged in an inclined state.

The conventional paper folding machine is configured as described above, and its operation will be explained below.

First, the paper 5 sent to the passage 1a of the guide body 1 is sent downward by the presser roller 3 and the folding roller 2a, and the leading edge of the paper 5 is sent downward through the passage 4a of the folded body 4. When the leading edge of the paper 5 comes into contact with the closed end 4b of the surface passage 4a, the paper 5 is inserted between the prayer rollers 2a and 2b in a bent state at approximately the center 5a, and is bent as shown in FIG. As shown, the sheets are folded in two, overlap each other, and are continuously sent out.

Problems to be Solved by the C0 Invention The conventional paper folding Qfi is configured as described above, and therefore has the following problems. Since the sheets of paper 5 are fed out in the horizontal direction, the fed out sheets of paper 5 overlap each other in the horizontal direction, as shown in FIG. For example, if there is a request to stack election papers folded in half and opened in a V-shape, the completely folded papers cannot be stacked in a V-shape and are lined up in the storage box. I was unable to comply with such a request.

Further, as described above, the paper that is continuously stacked in the horizontal direction and sent out is bulky and requires a large storage space, making it unsuitable for use as election paper.

Furthermore, when counting the number of sheets of paper using a counting machine, it was impossible to count the number of sheets of paper in the conventional state.

The present invention has been made to solve the above-mentioned problems. In particular, when stacking two sheets of paper folded in a V-shape, it is possible to avoid stacking errors (in a good manner). The purpose of the present invention is to provide paper folding iso which can be stacked in a well-aligned state.

d. Means for Solving the Problems The paper folding iso according to the present invention is such that the fed paper is folded in half by a pair of paper folding rollers and stacked in a receiving box with valley forming portions q. , the paper folding surfaces of each paper folding σ-ra are configured to form a predetermined gap with each other and are held in a non-contact state.

Further, there is a paper folding machine according to another invention, in which the fed paper is folded in half by a pair of paper folding rollers and stacked in a receiving box having a valley forming part, wherein each of the paper folding rollers , a contact portion that contacts each other and a non-contact portion that does not contact each other.

e. Function In the paper folding machine according to the present invention, since the pair of paper folding rollers are held in a non-contact state, when the paper is folded in half by these paper folding rollers, the crease is not completely folded. Because it is in a lightly folded state, it has a restoring force with sufficient elasticity, and when piled up in the valley forming part of the receiving box, it will not cause stacking mistakes and will open in a V-shape. piled up in the state.

In addition, in the case of the other invention described above, each paper folding roller is composed of a portion that contacts each other and a portion that does not contact each other, so that the fold line of the paper is made up of a completely folded portion and a lightly folded non-folded portion. Since this non-folding part has a restoring force with sufficient elasticity, when it is shaped into a ■ shape and piled up in the valley forming part of the receiving box, it will not cause a stacking error and will be completely V. They are piled up in an open shape.

f. Examples Hereinafter, preferred embodiments of the paper folding margin according to the present invention will be explained in detail with reference to the drawings. 6 The country names from FIG. 1 to 6 are for showing the paper folding machine according to the present invention, and FIG. 2 is an enlarged VT configuration diagram showing the main parts of FIG. 1. FIG. 3 is a configuration diagram showing another embodiment of the main parts of FIG. 1. FIG. 4 is a diagram showing the main parts of FIG. FIGS. 5 and 6 are plan views showing other embodiments of the configuration shown in FIG. 4.

It should be noted that the same or equivalent parts as in the conventional example will be described with the same reference numerals.

What is indicated by the reference numeral 6 in the figure is a paper feed base plate that is configured to be movable up and down by a handle 7 provided on the frame 7A. 5 are stacked on top of each other.

A feeding roller 28 is provided above the paper feed base plate 6, and a pair of folding rollers 2a and 2b having a feeding function are arranged in a substantially horizontal position adjacent to the feeding roller 8. The folding rollers 2a and 2b rotate in opposite directions, and the friction members 20
Alternatively, they are in contact via the gear member 22.

The folding roller 2a is provided at its end with a pulley 9 having a diameter larger than that of the folding roller 2a, and this pulley 9 drives a drive motor 10 attached to the frame 7A. It is connected to a pulley 11 via a belt 12.

Further, a press roller 3 is rotatably provided above the prayer roller 2a, and the press roller 3 is connected to the folding roller 2a, and above the prayer roller 22b, the paper 5 that has been fed is A stopper body 4 is provided with a stopper 4b for stopping the movement of the paper 5. !4 Adjustment screws 111 and 13 are provided for adjustment.

At a position below each of the folding rollers 2a and 2b, a receiving box 14 having a V-shaped valley forming part 14a is provided on the holding bar 15, and an id protrusion 14b of this receiving box 14 is formed on the holding bar 15. By being able to slide within the slotted hole 5a, the receiving box 14 can be selectively moved to two positions shown by solid lines and dotted lines in FIG.

Further, a holding plate 16 is provided between the receiving box 14 and each of the folding rollers 2a and 2b, and a pair of III antistatic devices 17 are provided at both ends of the holding plate 16. An opening 18 is formed between each antistatic device 17 to allow the paper 5 to pass through.

Furthermore, each of the above-mentioned paper folding rollers 2a and 2b is constructed as shown in FIG. The members 20 are in contact with each other, and the diameter of one roller 2b is smaller than the outer diameter of the friction member 20, so the paper folding surfaces 21 of each roller 2a and 2b are kept in a non-contact state, A gap is formed.

This gap is approximately 0.6 + aI when folding the election paper.
I+l: Set.

In another embodiment shown in FIG. 5, a gear member 22 is used instead of the friction member 20.

FIG. 6 shows the configuration of another embodiment in which the paper folding rollers 2a and 2b are rotated independently in opposite directions without contacting each other via rollers (not shown) or the like.

The paper folding machine according to the present invention is constructed as described above, and its operation will be explained below.

First, as shown in FIG. 1, when the drive motor 10 is activated with sheets of paper 5 stacked one on top of the other, the feed roller 8, each paper folding roller 2a, 2b, and the presser roller 3 start rotating at the same time.

In this case, the peripheral speed ratio is set so that the peripheral speed of each paper folding roller 2a, 2b is faster than the peripheral speed of the feed roller 8.

The paper 5 fed out by the feeding roller 8 is transferred to the presser roller 3
The paper 5 is fed into the stopper body 4 via the id passage 4a by the paper folding roller 2a, and the leading edge of the paper 5 is fed into the stopper body 4 by the paper folding roller 2a.
When the paper comes into contact with the stopper 4b and its feeding stops, the almost central part of the paper bends downward, and each paper folding roller 2a,
It is held in the gap between 2b and sent downward. In the above-mentioned state, the paper 5 is fed within the width 11 shown in FIG. The restoring force of 5 is maintained, and the V-shaped open state is maintained immediately after folding.

After the static electricity is removed by the e-static preventer 17, the folded paper 5 sent downward as described above is piled up in a V-shaped open state on the valley-shaped bottom 14a of the receiving box 14. be done.

With a predetermined number of sheets of paper 5 piled up, by stopping the operation of the drive motor 10 and pulling the receiving box 14 by hand, the receiving box 14 moves from the solid line position to the dotted line position, and the receiving box 14 The paper 5 inside can be taken out.

Furthermore, the configuration shown in FIG. 3 shows another embodiment of the receiving box 14, in which a part of the valley-shaped bottom 14a is composed of an opening/closing bottom 14a^ made of an elastic material, and when a predetermined overlap occurs, Third
As shown by the dotted line in the figure, it is in an open state and the paper 5 is continuously ejected to the outside.

Further, after the paper 5 is discharged, when the weight of the paper 5 in the receiving box 14 decreases, the opening/closing bottom part 14a is configured to return to its original closed state.

In the above-mentioned embodiment, when feeding the paper 5 to each paper folding roller 2a and 2b, the width of the paper 5 is within the width 21 shown in FIG.
When the paper 5 is almost the same as the above, only both ends of the paper 5 are completely folded by the contact portions 30 where each friction member 20 contacts, and the other portions are folded loosely by the non-contact portions 31 formed by gaps, so that the paper 5 is not folded. The subsequent sheets of paper 5 are stacked in a V-shape in the same manner as described above.

Furthermore, as shown in FIG. 5, when a gear member 22 is used in place of the friction member 20, the same effect as that of a multi-layer structure can be obtained.

Moreover, as shown in FIG. 6, each paper folding reroller 2a and 2b
A similar effect can be obtained if the two are made to rotate independently without contacting each other completely.

Furthermore, in the case of the configuration shown in FIGS. 4 and 5, the friction member 20 and the gear member 22 do not necessarily need to be located at both ends, but may be located at any position.

g. Effects of the Invention Since the paper folding machine according to the present invention is configured as described above, the following effects can be obtained.

In other words, since the folded part is not completely folded but is folded loosely with gaps, the paper after folding has sufficient restoring force, so it immediately returns to the V-shaped state, which can cause stacking errors. For example, the election papers can be folded in half and stacked on top of each other.

Furthermore, when counting the number of sheets of paper, the sheets are stacked perfectly without any errors, so when counting with a counting machine, no counting errors occur and high reliability can be obtained.
