Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to two fold lines having two fold lines on a target singular sheet or an appropriate number of sheets of paper (document) and having a maximum work amount for sending a document while having a simple structure. Is a device that can efficiently create a tri-folded document from a place that has a function of reliably attaching and maintaining accurate intervals.

[0002]

2. Description of the Related Art In recent years, the necessity of sending a large amount of documents has been increasing year by year without being limited to direct mail, and the work volume has been considerably increased not only in large companies but also in small and medium-sized companies. Improving gender is widely demanded in society. A central problem of such an operation is an operation of reliably forming two folds at an appropriate interval when preparing three folds at an appropriate interval on a sheet of paper. In response to such demands, large corporations have introduced expensive large electric machines to solve the problem, but small and medium-sized enterprises, etc. Even if the document does not become a tri-fold document, there is a strong demand for a device that can be properly folded at the center of the work load, has a low cost, has a simple structure, has good workability, and is easy to maintain and manage.

[0003]

SUMMARY OF THE INVENTION The purpose of the present invention is, as a matter of fact, that large equipment cannot be introduced, or that it is easy to operate with a simple structure in accordance with the demands of unsuitable customers. Invented a device that is similar to the performance of a large device at a low price.

[0004]

The present inventor has a press mechanism and a main plate, an auxiliary plate, a bottom plate, and a roll mechanism on the bottom plate for performing three-folding of the paper. We have invented a paper (document) tri-folder with a simple structure that has the function of maintaining and attaching the gap. The mechanism and operation outline of each of them will be described below.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given below with reference to FIGS. FIG. 1 is a side view of the device, FIG. 2 is a bird's-eye view showing a folding function of the device, and FIG. 3 is an explanatory diagram of a folding principle that complements the description of FIG.

First, the press mechanism will be described. Along with the outer periphery of the main pillar (1), the press mechanism (3) has a press bar
(2) Press bar from the starting point (18) of the press bar
It is connected to the lower press bar auxiliary part (2 ') through the operation stopper (21) and is machined so that it can move up and down. In the stationary state, the main pillar (1) is contracted by the contractible spring (4). It is located at the upper part by a spring holding mechanism (20) integrated with the upper part. This mechanism (3) is integrated with a part (16) that functions as a fulcrum (17) of the press bar, a press main plate (5), and two auxiliary plates (7) connected thereto.
The shape of the main pillar (1) is arbitrary, but a square shape is desirable for ensuring the operability and long-term dimensional stability of the equipment. In actual use, press mechanism (3) along main pillar (1)
The lubricating oil is applied to the vertical movement of the shaft and the starting point and the fulcrum of the press bar.

Next, the operation of the press mechanism will be described.
A support mechanism in which a press fulcrum (17) is attached to a press movable body (3) closely contacting the outer periphery of the main column (1) with a starting point (18) of a press bar (2) provided at an intermediate portion of the main column as a base axis. (16) is joined, and the main plate (5) and the auxiliary plate (7), which are joined in accordance with the lowering of the press bar (2), are connected to the base via the target paper (document) for the target press. It will be crimped. A contractible spring (4) is attached between the spring holding mechanism (20) and the main plate (5), and when the press by the press bar (2) is completed, the contraction is restored to the original upper position. It will be.

The auxiliary plate (7) is mounted at a position near both ends of the lower surface of the main plate (5) by means of a suitable hinge (6) or the like, and has mobility so as to be aligned with the main plate (5). Have.
However, there is a mechanism that blocks the light so as not to go beyond a certain angle, that is, in a direction approaching a right angle with the main plate (5). In the situation shown in the upper part of FIG. 3, the length (A) connecting the two leading ends of the auxiliary plates (7) on both sides is lowered in a situation shorter than the distance (B) between the two rolls. On the bottom plate (11), which has paper (document 1)
This situation will continue until you touch while pressing on 3). After contact with the target paper (document 13), the leading edge of the paper (document 13) slides on the surface of the target paper (document 13), and then the paper (document 13) is further rolled. It is inserted into the slight gap between the bottom plate (11) and the two presses to form two distinct folds on the target paper (document 13). In order to enable this pressure-bonding action to be effective according to the number of paper sheets, a function capable of finely adjusting the gap length is required, and a bearing portion of a column (10) supporting the roll (8) is required. (9) is manufactured to have this function. In the situation shown in the lower view of FIG. 3 in which the main plate (5) and the two auxiliary plates (7) are aligned, the state of the target paper (document 13) is shown by the dotted line.

When starting the folding operation, the target paper (document 13) to be folded and other related positions are shown in FIG.
As shown in the top view of FIG. 3 and the top view of FIG.
Auxiliary plate (7) is integrated, bottom plate (11), roll (8)
Is indicated by a middle dotted line as a unit. By lowering the press bar (2), the main plate (5) and the auxiliary plate (7) are moved by the press mechanism (3) which can move up and down as shown in the lower view of FIG. 2 and the lower view of FIG.
1) Add one or more sheets of paper (document /
13), and press the bottom plate (1) through paper (document 13).
When the auxiliary plate (7) touches 1) and becomes horizontal and is aligned with the main plate (5), the total width of the main plate (5) and the auxiliary plate (7) is as shown in FIG.
It is manufactured so as to be equivalent to the distance (C) between the two roll mechanism columns shown in the upper view (C).

As a method of keeping (A) related to the auxiliary plate (7) and the roll (8) shorter than (B), a contractible spring (15) is connected to a part (19) of both auxiliary plates. It is possible if it is installed corresponding to. However, it is necessary to install a stopper so that the distance shown in FIG.

The roll support (10) is fixed to the bottom (1) with screws or the like.
A groove is provided so that the distance between them can be adjusted so that it can be fixed to 1), and the auxiliary plate (7) is also detachable from the hinge part (6) so that the width can be adjusted by replacing the plate, The model in which the distance (C) in the target lower view of FIG. 3 is adjustable can cope with a change in the size of the paper (document / 13).

[0012]

According to the simple paper tri-folding machine having the above-mentioned mechanism, although the document is not completely folded in three, the two folds, which are the center of the work load, are accurately formed at appropriate intervals. It has a simple structure and a low risk of occurrence of breakdowns, has excellent workability, and is more efficient than similar ones, especially in small and medium-sized enterprises. It contributes to.
