Description

  The present invention relates to a paper folding means in 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 folded letter is manufactured by a sealing device or the like, and can be manufactured by using a continuous form folding facility described in, for example, Japanese Patent Application Laid-Open No. 09-202520.

  By the way, the continuous form folding equipment has a folding device 35 that folds the continuous form in which the unit forms 3 are connected by the horizontal perforations 4 along the feed direction, and the folding device has a plurality of pieces for winding the continuous form. Guide rods 36, 37, 38, and 39, and a guide rod 37 positioned on the supply unit side to hold the continuous form and a brush body 43 that imparts resistance in the feed direction to the continuous form. With such a configuration, it is possible to eliminate the continuous form cutting at the time of restart and the folding error at the end of the continuous form.

JP 09-202520 A

  The continuous form folding equipment should be able to eliminate the folding error due to the contents described above. However, in reality, depending on the quality of the paper used, the amount of paper, the brand, etc., it is not possible to avoid the occurrence of misalignment corresponding to all conditions with the above configuration. That is, as shown in FIG. 7, the fold line 2a folded by the first ball bar 41 passes through the gap between the ball adjusted at a constant interval and the bent bar and is sandwiched and folded by the gap. Depending on the paper quality (quality, matte coat, gloss coat, etc.), the amount of paper (70 kg, 90 kg, 110 kg, 135 kg, etc. in 4/6 format) and brand (Oji Paper, Nippon Paper, Mitsubishi Paper, etc.) Since the thickness and the repulsive force with respect to the folding force are slightly different, the ball bar adjusted at the predetermined interval cannot cope with it.

  Further, as shown in FIG. 7, it is technically difficult to adjust the fine gap between the ball and the bar by bending, and the accuracy of the finished product varies. As described above, coupled with the fact that the paper itself is slightly different in nature, if the accuracy of the bending process or the like goes wrong even a little, it will cause a folding error.

It can be displaced folding during operation of the site operator when generated, by changing the arrangement angle of at most folding device, so that the extent of work from locate the most well break location. However, even in such a case, it is not always possible to work stably without folding for a long time, and the arrangement angle of the folding device must be corrected many times.

In order to avoid such trouble, it is only necessary to prepare several types of intervals between the ball and the bar with a plurality of folding devices, and to select and arrange the optimal folding device before the work. the not only require a large storage plant by more than one owner, it is economically extremely unreasonable.
The present invention has been made in view of such circumstances, and in the paper folding means composed of balls and bars of a continuous paper folding device, a single folding device can be used for paper of any paper quality, quantity, brand, etc. The present invention provides a paper folding means in an economical continuous paper folding device that can cope with the situation even if the paper conditions change during the operation.

In order to achieve the above object, the paper folding means in the continuous paper folding device of the present invention is a paper folding means of a device that continuously folds a continuous paper having a fold line formed in the longitudinal direction from the fold line. A support shaft on which a ball is attached in a movable state is attached to the block in a movable state, and the block is connected to another different block so that the different block can be moved to a bar. It is characterized by being installed in a proper state .

The connection may, for example, two blocks are connected so as to be freely adjusted interval therebetween, the other with more the two one shaft ball block is attached these blocks movably mounted one block may be allowed to freely adjusted spacing between the ball and the bar have a structure that is mounted movably in the bar.

In the above configuration, if mounted on a movable state along the ball spindle, yet wider range of selection of the movement position of the ball.

Also be attached movably to the device body folding the bars, the width of the optimum position of the selected paper folding means consisting of the arrangement is further increased. Since the bar has a rod shape, the moment increases, so it is preferable to fix the bar to the main body with two-point support.

  There is no particular limitation on the material of each member constituting the ball or other paper folding means, and it may be selected from metals, resins, ceramics, etc. that are resistant to wear. The surface may be subjected to fluorine processing or other wear resistance treatment.

According to the present invention, even in the conventional continuous sheet folding apparatus, the support shaft to which the ball is attached in a movable state is attached to the block in a movable state, and the block is attached to another block. By connecting to different blocks in a movable state and attaching a bar to the different blocks in a movable state, it can handle paper of any paper quality, quantity, brand, etc., and the paper conditions change during work Even if it is possible to respond immediately, it is economical because a single folding device can cope with the different conditions without requiring a place.

It is a top view of the conventional paper folding means.

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

As shown in FIG. 1, the continuous sheet S used in the present embodiment has, for example, a first leaf piece 1 , a second leaf piece 2, and a third leaf piece 3 that are folded lines 4 and 5 (not necessarily displayed but perforated or those articulated in the transverse direction through the folding may be in muscle) the unit sheet t is connected to the vertical direction through the tear line 6 (necessarily may be a necessary perforation instead or crease that appears), A marginal portion 9 provided with marginal holes 8 on both sides thereof is connected via a cut line 7 (not necessarily displayed but may be a perforation or a crease). The continuous paper S is formed in a Z-shaped cross section as shown in FIG. 1B by folding the fold line 4 and the fold line 5 in a valley by the continuous paper folding device provided with the paper folding means of the present invention. Are continuously folded and sent to a downstream processing step.

For example, in the continuous paper folding apparatus having the paper folding means of the present invention shown in FIG. 2, the continuous paper S passes through a pass line indicated by a one-dot chain line via the support rollers 11 and 12 and is fed by the paper folding means Z. Folded into a Z-shaped cross section.

As shown in FIGS. 5A, 5B and 6, the sheet folding means Z is movable in the direction of arrow P on the support shaft 22 to which the ball 21 is attached while being movable in the direction of arrow O. It will install to block 23b in the state. And said block 23b are connected by two screws 25 in a movable state in the direction of arrow R with another block 23a, further said block 23a and the mounting bar 24 in a movable along arrow Q state It has been. In addition, as a method of moving and fixing each member , a known method such as a method of screwing and moving and fixing each member , or a method of moving to an arbitrary position and fixing with a hexagon set screw or the like can be adopted.

Said paper folding means Z which is constituted by as movable members it is possible to vary the position of each member at any time. Therefore, each member can be moved and fixed to an optimal position where no folding shift occurs even if the paper quality, the amount of paper, the brand, etc. of the paper changes.

The gap between the bar 24 and the ball 21 of the sheet folding means Z configured in this way is shown in FIG. 3, while the continuous sheet S is pressed against the guide bar 13 while being folded into a valley fold at the folding line 5. It is raised to.

In the folding lines 4 are the time mountain fold, because the leaf 1 is lifted narrowed down at the same time as the folding of the leaf 2 and 3, the paper folding means Z Once you have corrected to facilitate folding of the ball bar 14 dare do not need. Then, as shown in FIG. 4, the long sheet S folded in a Z-shaped cross-section above the paper folding means Z is turned almost horizontally by a support roller (not shown) to the downstream processing step. It is sent.

In addition, this invention is not limited to the said Example.
For example, the guide bar 13 and the ball bar 14 are not necessarily required. Since the tension in the continuous paper S which is pulled upward occurs inverted by support rollers 12 can be folded from a relatively smooth fold line 4 simply by valley fold the folding line 5 by the sheet folding means Z.
In order to promote smooth folding, it is preferable to form the fold lines 4 and 5 by perforation. However, even if it is a fold line or the like, it can be easily handled by adjusting the positions of various members. be able to.
Further, if surface processing such as fluorine treatment is applied to various members constituting the continuous paper folding device and the paper folding means Z, the running of the continuous paper can be promoted more smoothly.
Further, in this embodiment, the content of folding the continuous paper S connected with the three leaf pieces into a Z-shaped cross section is described, but the continuous paper connected with the two leaf pieces can be continuously folded in two. . In this case, the sheet can be folded continuously in two by passing the sheet folding means Z.
