Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is intended to fold a continuous form along two folds in a sealed letter making device or the like that creates a large number of sealed letters from a continuous form on which predetermined items are printed. The present invention relates to a continuous form folding device for use in manufacturing.

[Conventional technology]

Conventionally, it is known to create a sealed letter from a continuous form 1 as shown in FIG. This continuous form 1
It has a perforated ear 1a, two longitudinal folds 2a, 2b, and lateral folds 3, 3,..., And the like. Formed in the left column, data such as address 4
Are usually printed in a predetermined order, for example, in the order of eye-weather. The continuous form 1 is supplied in a state where the folds 3, 3... Are alternately mountain-folded and valley-folded, and while being pulled out, folded along the two folds 2a, 2b as shown in FIG. After removing the side edge 1a, the folds 3,3 ...
Is cut off, and then the peripheral portion of the sealed letter is bonded with an adhesive (for example, a pressure-sensitive adhesive) provided in advance. As a result, many sealed letters 1A are created as shown in FIG. For convenience of description, the order of the data 4 printed as the address is No. 1, No. 2, No.
It is indicated by a serial number such as 3.

As shown in FIG. 17, a conventional apparatus for producing a sealed letter from the continuous form 1 is a continuous form 1 that is continuously drawn from a folded continuous form 1B.
Foldable device 6A that folds the fold along the two folds in the longitudinal direction and a guide 6B for firmly folding the fold by passing the continuous form while pressing the continuous form. A mechanism 6, a transport pin tractor 7 for horizontally transporting the folded continuous form 1, a slitter 8 for cutting the ears 1a on both sides of the continuous form 1, and a longitudinal direction of the folded continuous form 1; The lower roller 10a, 10b, the upper roller 11a, 11b, and the cutter 12 which form the bar star part 9 for cutting in the horizontal direction, and the adhesive part 13 which adheres the seal part of the continuous form overlapped are comprised. Roller 14a, 14b to be pressed and upper roller 1 to be pressed against it
5a, 15b, and a stack 16 for stacking the created sealed letters 1A, etc., the continuous form 1 is folded by the folding mechanism 6, and the ears 1a at both ends are separated by the slitter 8,
Thereafter, it was cut to a predetermined length by the burster portion 9 and then strongly pressed by the upper and lower rollers at the bonding portion 13 so that the seal portions were bonded to each other to form a sealed letter 1A, which was integrated in the stack portion 16. .

Here, the conventional folding mechanism 6 arranges the continuous form 1 such that the left column is in front, ie, S
It was configured to be folded in a letter shape and overlap. Also,
The folding device 6A is pulled out from the guides 23 and 24 (see FIG. 17) for guiding the continuous form 1 drawn from the continuous form 1B placed in a folded state, and is drawn upward from the guide 24 in FIG. A triangular bar (not shown) arranged to push out one fold 2b of the continuous form to the front side, a first ball bar 26 having a narrow gap formed so as to squeeze the fold 2b, A second ball bar 27 and the like were provided so as to push the other fold 2a to the back side.

[Problems to be solved by the invention]

However, in the sealed letter producing apparatus having the above-described configuration, as shown in FIG. 18, the continuous form 1 is folded so that the surface to be the front face of the sealed letter (address printing face) is on the upper side, and the apparatus is arranged in ascending order of data number. (Hereinafter, this way of passing is referred to as “lower-numbered heading-through”.) Since the continuous form 1 is fed out in ascending order of the data number, the created sealed letters are successively higher in the stack part with the table facing upward. Things are stacked up. In other words, as shown in Fig. 16, the sealed letter 1A has No. 2
Are stacked on top of it in the order No.3. When the sealed letters are stacked in this way, there is a problem that it is inconvenient to check and sort the completed sealed letters. In this specification, the stacking state as shown in FIG. 16 is referred to as “the order and the front and back do not match”, and conversely, when the address side of the sealed letter is up, the younger number is on top. The stacked state is called "the order and the front and back coincide."

In order to accumulate the sealed letters so that the order and the front and back coincide with each other, the continuous form 1 may be passed through the apparatus so that the address printing surface is on the lower side, that is, the so-called first-order-first-through may be performed. However, in the case of pass-through, the printed surface is on the lower side, so that the printed contents cannot be seen during operation of the apparatus. Further, since the printing surface faces downward, dirt adheres to the lower roller disposed on the lower side, which causes problems such as difficulty in cleaning and inability to see the degree of dirt.

In order to solve these problems, the continuous form should be passed through the device with the printed side up and the largest number of printed data. ). However, in order to perform such a passing method, instead of folding the continuous form 1 in an S-shape as shown in FIG. 18, a Z-shape in which the left column of the continuous form is in front (FIG. 2) ), And such a folding method cannot be performed with the conventional folding device 6A. Therefore, there arises a problem that another dedicated folding device must be provided in order to perform the Z-shaped folding. Also, depending on the continuous form, there is a case where it is necessary to look through the youngest number, so in that case, it is necessary to replace the folding device.

Furthermore, in the conventional folding device 6A, the lower guide
The folds 2a and 2b of the continuous form 1 that has passed through 24 are deformed into a mountain shape and a valley shape, and one of the folds 2b is immediately squeezed and folded by the first ball bar 26. With such a configuration, the horizontal folds 3, 3.
(Alternatively, mountain folds and valley folds) may be caught when passing through the narrowed portion of the first ball bar 26, and break the continuous form. In addition, there is a problem that the processing speed of the entire apparatus is limited due to the passage resistance due to the throttle section.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and it is possible to fold a continuous form into any of an S-shape and a Z-shape, and to reduce the passage resistance to increase the speed of the continuous form. It is an object of the present invention to provide a hammering device.

[Means for solving the problem]

The present invention will be described with reference to the embodiment shown in FIGS. 1 to 12. The folding device 30A of the present invention is disposed substantially at right angles to the traveling direction of the continuous form 1 to be drawn out. And a guide 33 which guides the continuous form, is disposed at a position parallel to the guide at a running position of the continuous form passing through the guide and at a position substantially symmetrical with respect to a running center axis of the continuous form. A pair of folding members 34, 34 for folding the two folds of the form in opposite directions, and a running position of the continuous form passing through the pair of folding members, spaced apart in a direction parallel to the guide, and It is characterized in that it has a pair of throttle members 36, 36 which are arranged at positions substantially symmetrical with respect to the traveling center axis, and which narrow a portion outside the two folds of the continuous form.

[Action]

When the continuous form 1 is passed through the folding device 30A having the above structure as shown in FIGS. 5 to 7, the continuous form 1 drawn out in a flat state through the guide 33 is shown in FIG. As shown in the figure, the left folding member 34 deforms the fold 2a into a mountain shape, the other folding member 34 deforms the fold 2b into a valley shape, and the diaphragm members 36, 36 above the fold 2a as shown in FIG. The outer portions of the folds 2a and 2b of the continuous form can be restrained from the outside, and the continuous form 1 can have a Z-shaped fold. When the continuous form 1 is passed through as shown in FIGS. 8 to 10, each fold of the continuous form 1 is bent in the opposite manner to the above, so that it can be finally folded into an S-shape. Although the folding device 30A cannot firmly fold each fold of the continuous form 1, each fold can be firmly pressed by pressing the folded continuous form 1 against an appropriate guide or squeezing by an appropriate means. Can be folded.

Further, in the folding device having the above configuration, the folding member,
The squeezing member roughly folds the continuous form,
Since the folds are not tightly folded and folded, the continuous folds such as mountain folds and valley folds of the continuous form can be easily passed, and the breakage of the continuous form can be prevented, and the processing speed can be increased.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view of a letter forming apparatus provided with a folding device according to one embodiment of the present invention, and the same parts as those in the conventional example of FIG. 17 are denoted by the same reference numerals. In FIG. 1, 1 is a continuous form on which predetermined data is printed as shown in FIG. 13, 1B is a continuous form folded and placed, 30
Is a folding mechanism that folds and overlaps the continuous form 1 continuously taken out of the folded continuous form 1B along two longitudinal folds. It has a folding device 30A for deforming it so as to be folded and overlapped along the fold of the book, and a guide 30B for firmly folding the fold by passing the continuous form while being pressed. Details will be described later. 7 is a transport pin tractor for horizontally transporting the superposed continuous form, 8 is a slitter for cutting the ears 1a on both sides of the continuous form 1, and 9 is a transversely extending superposed continuous form 1 in the longitudinal direction. This is a bar star section that constitutes a means for cutting in the direction, and includes lower rollers 10a and 10b, upper rollers 11a and 11b, and a cutter 12. Reference numeral 13 denotes an adhesive portion which constitutes a means for adhering the seal portions of the continuous foams superimposed, and includes lower rollers 14a and 14b and upper rollers 15a and 15b pressed against the lower rollers 14a and 14b. Reference numeral 16 denotes a stack unit for stacking the created sealed letters 1A. As the other members except for the folding mechanism 30, conventionally known members can be used. Note that the burster section 9 and the bonding section 13 may be interchanged.

The folding device 30A can fold the continuous form 1 so that the right column is in the front as shown in FIG. 2, that is, it can be folded in a Z shape, and as shown in FIG. It can be folded. FIG. 3 is a schematic perspective view showing the folding device 30A. In FIG. 3, 31 is a folded continuous form 1B (see FIG. 1).
The bases 32, 33 on which the sheet is placed are rod-shaped guides for guiding the continuous form 1 to be drawn, and are provided in parallel to the base 31, and are therefore arranged substantially at right angles to the traveling direction of the continuous form to be drawn. 34, 34 are spaced apart in the direction parallel to the guide 33 at the running position of the continuous form that has passed the guide 33 (that is, spaced apart from each other on a straight line parallel to the guide 33). A pair of folding members are disposed at positions substantially symmetrical with respect to the running center axis of the foam, and bend the two folds of the continuous foam in opposite directions. In this embodiment, a large-diameter ball is used. . Reference numerals 35, 35 denote support arms holding the folding members 34, 34, respectively, and are arranged on one straight line parallel to the lower guide 33. 36, 36 are arranged at the running position of the continuous form passing through the pair of folding members 34, 34, at intervals in a direction parallel to the guide 33 and at positions substantially symmetric with respect to the running center axis of the continuous form, A pair of squeezing members for squeezing portions outside the two folds of the continuous form. In this embodiment, small-diameter spheres are used. 37, 37 are support arms holding the folding members 36, 36, respectively, and are arranged on one straight line parallel to the lower guide 33. 38, 38 are side frames. Straightening device 30A with the above configuration
As shown in FIG. 4, is arranged so as to be inclined with respect to the running direction (arrow X direction) of the continuous form in the apparatus main body 40.

Next, the operation of the sealed letter preparing device using the folding device 30A having the above configuration will be described.

In Figure 1, the folded continuous form 1B is the guide
The continuous form 1 which is set below 33 and pulled out therefrom passes through the guides 32, 33 and is then folded by the folding member 34, the squeezing member 36 and the guide above it.
When it is pressed against 30B and passes, it is folded tightly. At this time, the continuous form 1 is shown in FIGS. 5, 6, and 7.
As shown in the figure, it passes between the folding members 34, 34 and between the aperture members 36, 36. The folding members 34, 34 are located on both sides of the continuous form 1 passing therethrough, and the folds 2a, 2b of the flat continuous form 1 passing through the guide 33 are curved in opposite directions to be folded. That is, in FIG. 7, the left folding member 34 deforms the fold 2a into a mountain shape, and the other folding member 34 deforms the fold 2b into a valley shape. At this time, a large-diameter folding member 34 is used so that the continuous form 1 can be largely bent. Next, the aperture members 36, 36
As shown in FIG. 6, the outer portions of the folds 2a, 2b of the continuous form bent by the folding members 34, 34 are restrained from the outside, whereby the continuous form 1 is further bent. FIGS. 5 to 7 show a state in which the continuous form 1 is bent so that the folds 2a and 2b form an angle.
In many cases, the shape is curved in an arc shape at a and 2b.

In FIG. 1, the continuous form 1 (see FIG. 7), which has been bent in a substantially Z-shape between a pair of throttle members 36, 36, is thereafter pressed by an upper guide 30B and passes therethrough. Each fold 2a, 2b is folded firmly. Thus, as shown in FIG. 2, the continuous form 1 is folded in a Z-shape and supplied to the downstream pin tractor and thereafter. In FIG. 1, an appropriate means for folding the folds 2a and 2b may be provided at or below the guide 30B as necessary.

When the continuous form 1 is set in the sealed letter forming apparatus having the above-described configuration, the data 4
The continuous form 1 is pulled out from the side with the largest number, and passed through the apparatus so that the addressing surface is on the top. As a result, the continuous form 1 is put through the old count (see Fig. 2)
Becomes The envelope creation operation is performed in the same manner as in the related art.

Thus, when the above-mentioned folding device 30A is used,
When the continuous form 1 is passed through, the operator can perform the operation while checking the printing surface while the continuous form 1 is running. Since it is the upper roller, cleaning is easy and dirt can be easily determined. In addition, by passing through the old number, it is possible to stack the letters in the stack section 16 with the address side of the sealed letter upward and the young number on the large number.

Furthermore, in the above folding device 30A, the pair of folding members 34, 34 and the squeezing members 36, 36 are both roughly folded, but are not the ones that squeeze the folds 2a or 2b as in the conventional case. The folds 3, 3,... Which have just been pulled out through the guide 33 and still have some folds or valleys can be passed without any trouble, and no trouble occurs. When the continuous form 1 is folded by the folding members 34, 34 and the squeezing members 36, 36, the mountain folds and valley folds of the horizontal folds 3, 3,. There is no problem even if the folds 2a and 2b are squeezed afterwards.
Can be folded well. Thus, the speed can be increased.

Although the above description has been made of the case where the addressing face is on the upper side, by setting the continuous form 1 so that the addressing face is on the lower side, it is also possible to pass through the old numbering head.

Further, the folding device 30A having the above-described configuration can also perform a pass-through operation with a small number. In this case, the continuous form 1 is pulled out from the side with the smaller data number, and
It may be passed as shown in FIG. 9, FIG. 9 and FIG. Then
In FIG. 10, the left folding member 34 deforms the fold 2a into a valley shape, and the other folding member 34 deforms the fold 2b into a mountain shape. Thus, the continuous form 1 that has passed between the upper squeezing members 36, 36 has an S-shape as shown in FIG. 9, and performs the lower-ranking look-through as shown in FIG. be able to. In addition, by making the print side down,
It is also possible to pass through the youngest player.

In the above embodiment, each of the folding member 34 and the aperture member 36 is formed of a sphere, but these shapes are not necessarily limited to spheres and can be changed. For example, as the folding member, a ring-shaped folding member 34A shown in FIG. 11A and a folding member 34B connecting two small balls shown in FIG. 11B may be used. The twelfth
As shown in the figure, a frame 42 surrounding the folding members 34, 34 may be provided to regulate the running position of the continuous form.

〔The invention's effect〕

As described above, according to the folding device of the present invention,
It is possible to bend the continuous form into either an S-shape or a Z-shape. Therefore, it is not necessary to replace or change the position of the sealed letter making device. There is an effect that any of the younger heading through, the older heading out, and the older heading out can be performed.

In addition, since the continuous form is not sharply drawn, the processing speed can be increased without causing breakage or the like even if the continuous form passes through a horizontal fold such as a mountain fold or a valley fold. It also has an effect.
