Abstract

<P>PROBLEM TO BE SOLVED: To provide a folding device for continuous paper improving efficiency by making a processing flow in a system into a straight line, though a folding part in a conventional system using a long-sized sheet makes the processing flow into an L-shaped flow. <P>SOLUTION: Reversals are repeated by obliquely crossing rollers 3, 4 and 5, maintaining the flow of the long-sized sheet S in a straight line direction. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a continuous paper folding device used when folding continuous paper such as form printing paper or rotary printing paper and sending it to a downstream processing step.

  Conventionally, folded letters such as bi-fold or tri-fold sealed letters, postcards, forms, etc. have been used for many mailings such as direct mail and various notices.

  The folding letter is manufactured by a sealing device or the like, and as a manufacturing method thereof, for example, a continuous paper processing device described in Japanese Patent Application Laid-Open No. 09-067063 or Japanese Patent Application Laid-Open No. 09-272660 is manufactured. Can do.

By the way, in the continuous paper flow in the continuous paper processing apparatus, the paper flow direction changes approximately 90 degrees between the folding portion and the downstream processing step. Accordingly, the positions of the continuous paper feeding devices and the continuous paper processing device are arranged in an L shape. Although there is a folding apparatus in which the folding section of the continuous paper processing apparatus is independent (see, for example, Patent Documents 3 and 4), the arrangement of the entire process is similarly L-shaped when the folding apparatus is used.

  As described above, the system including the continuous paper processing device and the continuous paper feeding devices has an L-shaped arrangement. If another system such as a winder or an inter-stacker is connected to the upstream side of the folding unit, the layout of the L-shaped arrangement becomes more prominent. However, in the various printing machines and processing apparatuses arranged in the factory, the flow of the processed material such as paper to be processed is linear, and the machine itself is naturally arranged linearly. Under such circumstances, the L-shaped arrangement becomes a heterogeneous existence, and particularly in a small factory such as a small and medium-sized company, it is extremely difficult to secure a place for installation, and a significant trouble occurs.

  The present invention has been made in view of such circumstances, and in a system including a continuous sheet folding device, the flow direction of the processing path, that is, the flow direction of the continuous sheet is made linear from the conventional L-shaped flow direction. It is a thing. As a result, even in a small factory such as a small business, it is possible to install with sufficient margin without disturbing the arrangement of other systems around.

  In order to achieve the above object, the continuous paper folding means of the present invention is an apparatus for continuously folding a long sheet in which unit sheets in which a plurality of leaf pieces are connected in the horizontal direction via the fold line are connected in the vertical direction. And a step of turning the continuous paper fed from the upstream in a horizontal direction in a direction substantially perpendicular to the flow direction of the paper through the first roller and turning it back. It includes a step of raising substantially vertically through the second and third rollers, a step of folding continuous paper raised in the vertical direction, and a step of feeding the folded continuous paper in the original flow direction. .

According to the present invention, even in a small factory such as a small business, it can be installed with a margin without disturbing the arrangement of the surrounding system.
Therefore, a sufficient space with the surrounding system can be secured, the operator can settle down and work safely and work efficiency can be improved.

  Hereinafter, an embodiment of a continuous paper folding apparatus according to the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view of a long sheet. FIG. 2 is a perspective view of the folding device according to the present invention. FIG. 3 is a perspective view when FIG. 2 is viewed from another angle. 4A and 4B are a plan view and a side view showing the path of the long sheet. FIG. 5 is a plan view showing a state in which a long sheet is folded by a folding sewing machine.

  As shown in FIG. 1, the long sheet S is continuously fed from a roll or the like from the upstream of the process. The long sheet S of the present embodiment is divided into three equal parts by perforations 1 and 2, and as will be described later, it is folded into a Z-shaped cross section from each perforation to form a three-fold form. However, the present invention is not limited to this, and the present invention can be applied to bi-folding and deformation bi-folding.

  As shown in FIGS. 2 and 3, the long sheet S is sequentially fed out in the direction of the arrow from the lower process upstream side in the drawing. And it is reversed at an angle of 90 degrees or more with the first roller 3 (see FIG. 4A). As shown in FIG. 4B, the reversed long sheet S passes through the lower side of the second roller 4 and is inverted, passes through the lower side of the third roller 5 and stands up as it is. Raised.

  The long sheet S raised upward is folded in a Z-shaped section from the folding sewing machines 1 and 2 provided in the flow direction, and the flow is changed in the horizontal direction by the support roller 6 positioned in the upper part in the figure. It is transported to a downstream system (not shown).

  As shown in FIG. 5, for example, the folding machine portion pressed by the pressing roller 7 can be creased by pressing it between the sandwiching brackets 8 and 8. The other sewing machine surface can be folded along the support roller by pulling up along the guide bar 9 and then changing the direction horizontally with the support roller 6.

  Since the long sheet S folded in this manner is conveyed in the same flow direction (the direction of the arrow indicating the conveyance direction is the same) from the lower side in the drawing corresponding to the upstream side of the process in FIG. is there.

  It is also clear in FIG. 3 that the upstream and downstream systems have the same transport direction. The long sheet S rises from the upper left in the drawing to the support roller 6 in the upper right in the drawing and is conveyed to the right in the drawing downstream.

In addition, this invention is not limited to the said Example.
For example, although it is a guide bar, it is not necessarily required. The shape may be other different shapes, for example, a sphere may be provided at the tip or the center.
There are no particular restrictions on the shape of the sandwiched metal and the shape of the pressing roller.
Furthermore, although the Z-fold (three-fold) form has been described in the above embodiment, a simple two-fold form may be used, or a modified two-fold form that folds one part of a long sheet that is divided into three parts may be used. Absent.

It is a top view of a long sheet. It is a perspective view of the folding apparatus which concerns on this invention. It is a perspective view at the time of seeing FIG. 2 from another angle. (A) And (B) is the top view and side view which show the path | route of a elongate sheet | seat. It is a top view which shows a mode that a long paper is folded with a folding sewing machine.
