Abstract

PURPOSE:To ensure that forms are stacked over the other and are bonded together by stacking forms on a pin tractor wheel, then allowing the pin holes of each form to be engaged with the pins of the pin tractor wheel and applying an appropriate tension to each form. CONSTITUTION:Forms 11 are drawn out through a tension applying device 13 and a guide device 17, then are stacked over the other on a pin tractor wheel 22 and the stacked forms are transported. In this case, the forms 11 allow their holes 11a to fit into pins 22a smoothly, although the interval between the pin holes changes slightly due to the elongation and contraction of the form. This is because the pin hole 11a is opened larger than the pin 22a and also the pin tractor wheel 22 is not so long. In addition, each form 11 almost does not come in contact with the other form 11 and is guided to the pin tractor wheel 22. Therefore, the tip end of the pin hole 11a can be set in a state where the tip end is in contact with the pin 22a. Consequently, the forms 11 are stacked over the other at specified position exactly and bonded together.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a collating device for stacking a plurality of elongated forms having a predetermined pinch of pin holes on the side edges and pressing them together.

[Conventional technology]

Conventionally, a form binding method has been used in which a plurality of forms on which different contents are recorded or printed are stacked one on top of the other, and a portion (one end, one end, etc.) of the forms are glued together. One method of manufacturing this form binding is to record or print the specified contents on a long form with a predetermined pinch of bottle holes on the side edge, and then prepare a folded sheet. While pulling out the form, overlap it (work together),
A method is known in which the vicinity of one side edge or the vicinity of both side edges is bonded.

As shown in FIG. 7, the conventional collating device used in this method includes a plurality of form feeding units each having a form placing table 2 on which folded forms 1 are placed;
A tension imparting bar 3 and a pin wheel 4 are arranged above each form mounting table 2, a pin tractor 5 transports a plurality of stacked forms 1 via the pin wheel 4, and a roller 7 is arranged downstream of the pin tractor 5. A crimping device 1F consisting of a crimping roll 8 and a crimping roll 8
6 and a pin tractor 9 for sending out, etc., the pin wheel 4 pulls out the form 1 set on each form holder 2 through the tension applying bar 3, and the pin wheel 4 pulls out the form 1 one after another with each pin wheel 4. The pin tractor 5 sends all the three stacked forms 1 to a crimping bag W6, and the crimping device 6 presses the pressure-sensitive adhesive applied to each form 1 in advance to separate the forms. They were glued together, and then a pin tractor 9 sent the glued foam downstream. Note that a cutting device and a stuffing car (not shown) are provided downstream of the pin tractor 9 to cut the bonded foam into a predetermined size and stuff it.

Here, the distance between the pin tractor 5 and the adjacent pin wheel 4! , is set to an integral multiple of the pitch of the bottle holes formed in the form 1, and the interval between each pin wheel 4 is j! 2 is also set to an integral multiple of the pitch of the pin holes formed in form 1,
The pin holes of each form 1 could be engaged with the pins of each pin wheel 4 and pin tractor 5 without any trouble.

[Problem to be solved by the invention]

However, the collating device having such a configuration has the following problems. In other words, since the multiple forms that make up one form weave differ in paper quality, paper thickness, printing amount, etc., even if pin holes are initially formed in each form at a constant width,
The pin hole spacing of each form changes due to shrinkage and elongation due to moisture absorption, drying, etc. 2. Therefore, the elongated form is placed between each pin wheel 4 or between the pin wheel 4 and the pin tractor 5. In some cases, the pin of the pin tractor 5 may not be held well and the overlapping position with respect to other forms may be distorted. 4 and the pin tractor 5, and in some cases the tension becomes too great, causing the problem that the pin hole is torn. In order to prevent the form from sagging between each pin wheel 4 or between the pin wheel 4 and the pin tractor 5, it is sufficient to increase the interval between each pin wheel 4 or the interval between the pin wheel 4 and the pin tractor 5. , the mounting position of the pin wheel 4 is adjustable,
These intervals are adjusted, but if the interval between the pin wheels 4 or between the pin wheel 4 and the pin tractor 5 is lengthened in this way, the contracted form will be further stretched and the tension will increase. The pin hole will be easily torn. In addition, in order to prevent the pin hole from tearing, a humidifier is installed in front of the pin wheel 4 to make the foam easier to stretch. It is necessary to adjust the amount of humidification by adjusting the amount of humidification, which increases the size and cost of the device, and furthermore, it takes time and effort to adjust the amount of humidification.

Furthermore, the conventional device has a pin wheel 4 mounted above each form mounting table.
, and the pin wheels 4 are configured to be driven in synchronization with each other and with the pin tractor 5, resulting in a problem that the drive system is complicated and expensive.

The present invention has been made in view of the above problems, and is a collating method with a simple structure that allows two or more sheets to be stacked and collated without causing any slack or pin holes. The purpose is to provide equipment.

[Means to solve the problem]

The present invention, which has been made to achieve such an object, includes a plurality of form paper feeding units, and a tension applying device that applies tension to each of the forms pulled out from each of the form paper feeding units.

A guide device that guides a plurality of forms pulled out from a plurality of form paper feeders via a tension applying device so that they overlap each other while keeping them in a non-contact state; The gist of the present invention is a collating device that includes a pin tractor that conveys a plurality of forms in a stacked state, and a pressure bonding device that presses and adheres the plurality of forms sent out from the pin tractor to each other.

C Effect] In the collating device configured as described above, a plurality of forms are pulled out from a plurality of form feeding units via a tension applying device and a guide device, and are superimposed on a pin tractor.

By engaging the pin hole of each form with the pin of the pin tractor, the two forms are positioned relative to each other,
Thereafter, each form is bonded together using a crimping device.

Here, each form pulled out from each form feeding unit does not interfere with other forms (because it is guided by a pin tractor, the pin hole of each form is is engaged with the pin of the pin tractor, and the edge of the pin hole is brought into contact with the pin, and the pin is caused to travel by the pin.As a result, the respective forms are superimposed on each other at a predetermined position.

If multiple forms are overlapped before guiding them to the pin tractor, the friction between the forms will be large.

Even if only one of the forms is pulled, misalignment will occur between the forms. Therefore, once multiple forms are stacked on top of each other with their respective bottle holes misaligned, the situation cannot be corrected. The product is sent to the pin tractor without being misaligned, resulting in a defective product. Conventionally, in order to prevent this phenomenon, a pin wheel was placed above each form mounting stand, and nine forms were stacked one on top of the other without aligning each pin hole. However, the present invention can effectively overlap each form without using this pin wheel. Forms can be superimposed.

Collars 18a are attached to both ends of the turner 18 for regulating the running position of the foam 11 in the width direction. Furthermore, a collation mark sensor 20 is installed near the turnper 18, and the form 11 passing over the turnper 18 is
It is designed to detect the verification mark provided on the

22 is a pin tractor that transports a plurality of forms 11 pulled out through a guide device 17 in a superimposed state;
3 is a guide plate that guides the upper surface of the form conveyed by the pin tractor 22;
It has a groove 23a through which it passes. 24 is a lower guide plate that guides the lower surface of the form to the pin tractor 22. The pin tractor 22 and the guide plate 23 are arranged so that a plurality of forms 11 from the guide device 17 can be collected near the entrance of the pin tractor 22 and transported in a stacked manner, as shown in FIGS. 4 and 5. As shown, the pin 22a of the pin tractor 22 is inserted into each pin hole 11a of the plurality of forms 11.

The foam 11 is conveyed.

In FIGS. 1 to 3, 26 is a crimping device disposed downstream of the pin tractor 22, and a receiver disposed on the lower side includes a roll 27 and a crimping roll 28 disposed above it. . The pressure roll 28 is provided corresponding to the passage position of the pressure-sensitive adhesive applied in advance to the passing foam 11, and has pressure protrusions 28a at appropriate intervals on its two circumferential surfaces.
It is equipped with With this configuration, the receiver can hold the plurality of foams 11 passing between the roll 27 and the pressure roll 28.
Can be dot glued to each other.

The crimped foam 11 is further downstream of the crimping device 26.
A pin tractor 30 for discharging the foam, and a guide plate 31 for guiding the upper surface of the foam conveyed by the pin tractor 30 are provided. The distance between this pin tractor 30 and the upstream pin tractor 22 is set to be slightly shorter than an integral multiple of the pitch of the pin holes in the form, so that there is a slight slack in the form 11 between the pin tractor 22 and the pin tractor 30. is starting to grow. Furthermore, between the pair of pin tractors 30, a lower guide plate 32 for guiding the lower surface of the form and a presser guide 33 disposed on the upper part of the form are provided. The presser guide 33 has an upwardly inclined guide portion 33a at its tip and a bending portion 33b following the guide portion 33b.The bending portion 33b contacts the passing foam 11 and provides resistance, which is exaggerated in FIG. As shown in FIG. 2, the pin tractor 22 and the pin tractor 30 are attached so that the form 11 passing between them is curved upward in a convex shape. When the form 11 is curved upward in a convex manner by the presser guide 33, the travel path of the form 11 given the slack between the pin tractors 22 and 30 is stabilized, and the form 11 is stabilized. and the form 11 is kept flat in the width direction,
The deviation in the width direction of the side edges of the plurality of foams can be made extremely small. If such a convex curve is not formed, the plurality of forms 11 that have become free after leaving the pin tractor 22 may contain air while traveling, causing the central part in the width direction to bulge and cause the shapes 9 to curve on both sides. A phenomenon occurs in which the edges sag, and the size differs between the forms, causing the side edges of multiple forms to shift in the width direction, but the presser foot guide 3
3, such widthwise deviation can be made extremely small. here.

In order to stably curve the foam 11 upward, it is preferable to arrange the bent portion 33b of the presser guide 33 at a position where the foam 11 begins to be driven by the pin tractor 30. The mounting height of the bent portion 33b may be determined so that the bent portion 33b can contact the passing foam 11 and provide a resistance to the extent that it can be applied, depending on the number of sheets of the foam, the paper quality, the amount of slack, etc. There is no need to change much. In FIGS. 2 and 3, the presser guide 33 has its rear end supported by a support shaft 34, and can be rotated upward from the operating position shown in FIGS.

Although illustration is omitted downstream of the pin tractor 30.

A device for cutting the bonded foam into a predetermined size and removing unnecessary pin hole portions, and a stacker for collecting the cut foam are provided. Note that instead of providing a cutting device and a stacker, a device for simply folding and stacking the bonded foam may be provided.

Next, the T-coupling operation performed by the apparatus having the above configuration will be explained.

In FIG. 1, the forms 11 on which predetermined recording and printing have been performed are set on a plurality of form holders 12 in a folded state. From this form stand 12.

The set plurality of foams 11 are attached to the tension applying device 13
and is pulled out through the guide device 17, and the pin tractor 2
2 and transported. At this time, on the pin tractor 22, as shown in FIGS. 4 and 5.

The pin hole 11a of each form 11 is engaged with a pin 22a of the pin tractor 22, and the form 11 is conveyed by movement of the pin 22a. The plurality of forms 11 are
The pinch of the pin hole changes somewhat due to the expansion and contraction, but the pin hole 11a is made larger than the pin 22a, and the pin tractor 22 is not very long, so on the pin tractor 22, each of the multiple pins 22a is Form hole 1
1a can be guaranteed without any problem. Furthermore.

Since each form 11 pulled out from each form holder 12 is guided to the pin tractor 22 without almost contacting other forms 11 and therefore without interfering with each other, an appropriate tension can be applied to each form 11 by the tension applying device 13. As shown in FIG.

The tip edge of the bottle hole 11a of each form 11 can be brought into contact with the pin 22a of the pin tractor 22. In this way, by bringing the edge of the tip end of the bottle hole 11a of each form 11 into contact with the pin 22a, the plurality of forms 11 are overlapped with each other while being accurately positioned at a predetermined position, and the conveyance is facilitated. be done.

Here, the pitch of the bottle holes 11a and the pitch of the pins 22 of the pin tractor 22 are usually set to be equal to 2.

However, if form 1, as shown in FIG.
1 shrinks, and the pitch l of the bottle hole 11a becomes the pin 22a.
When the pin 22a is shorter than the pinch 14, the pin 22a on the tip side (right side) is in contact with the edge on the tip side of the bottle hole 11a, but the pin 22a on the rear side (left side) is inserted into the bottle hole 11a. Even if it is in this state, it does not contact the edge on the tip side, and a minute gap d is created. Therefore, pin 2 on the tip side
After the pin 2a comes out of the bottle hole 11a, the foam 11 needs to retreat relative to the pin tractor 22 by the gap d, and the movement of the foam 11 may lack smoothness.

To avoid this, set the pitch 14 of the pin 22a to the pitch of the bottle hole 11a. It is preferable to set it equal to or slightly smaller than .

A plurality of forms 1 overlapped by a pin tractor 22
1 is then dot-bonded by a crimping device 26 downstream of the pin tractor 22. Note that the plurality of forms 11 discharged from the pin tractor 22 are attached to the pin 2 of the pin tractor 22.
When the restraint by 2a is released, it becomes free, and when air is included during running, the central part in the width direction swells, and 1 both side edges hang downward, and the size of the deformation at that time overlaps between the forms. As a result, the side edges of the form shift in the width direction. However, in this embodiment, the presser guide 33 is provided at the pin tractor 30 on the downstream side, so that the form 11 takes a stable traveling path convexly curved upward when viewed from the side. The form 11 is stiffened and kept flat in one width direction to prevent deviation in one width direction, and is therefore bonded by a crimping device 26 with less deviation in one width direction. The foam 11 after being bonded is cut into a predetermined size downstream thereof and stacked.

In the above embodiment, the plurality of forms 11 are collected at the entrance of the pin tractor 22 and overlapped. However, the present invention is not limited to this case.
They may be superimposed one after another on the top.

Further, in the above embodiment, the pressure-sensitive adhesive was applied to the foam 11 in advance, but the present invention is not limited to this case. The adhesive may be applied before the foams 11 are overlapped.Furthermore, in the above embodiment, only the vicinity of one side edge of the foam 11 is adhered, but the adhesive position is limited to this position. This can be changed as appropriate, and there is no problem even if it is bonded at a plurality of locations (for example, near both side edges).

Further, in the embodiment described above, the elongated form is set in a folded state on the form holder of the form feeding section, but it is also possible to use a roll of form. In that case, a mechanism for setting the rolled form may be provided in the form feeding section in place of the form placing table.

[Effects of the Invention] As described above, according to the present invention, a plurality of forms are overlapped at the pin tractor, the pin holes of each form are engaged with the pins of the pin tractor, and an appropriate tension is applied to each form. By applying this, the edge on the tip side of the bottle hole can be brought into contact with the pin, and thereby, even if there is a slight difference in length between each form, each form can be correctly overlapped and bonded using the bottle hole as a reference. I can do it.

Moreover, it is upstream of the pin tractor.

There is no need to provide a pin wheel or the like connected to a drive system for each form feeding section as in the past, and it is sufficient to simply provide a mechanism that does not require driving, such as a tension applying device or a guide device. The equipment is simple and costs can be reduced,
Moreover, it has the advantage of being easy to adjust.
