Abstract

PURPOSE:To retain an offset amount in the width direction of forms to a minimum value after adhesion by providing a retaining guidance which gives a projecting curvature to the top of the forms as viewed from a lateral angle which passes between the first and the second pin tractor wheel. CONSTITUTION:Forms 11 discharged from the first pin tractor wheel 22, released from its restriction by a in 22a, absorb air in their run and consequently their center tends to become swollen and sag on the both ends, resulting in their easy lateral slip. In this case, a returning guide 33 provided at the second pin tractor wheel 30 gives appropriate resistance to the form 11 and allows the forms to assume a stable running route which is curved like a convex form as viewed from their lateral angle. Subsequently, as the form is flexible, it can be retained in a flat condition in its width direction. For this reason, a pressure device 26 can be bonded with the least offset amount in its width direction. Further the height of the retaining guide 33 need not be finely adjusted when it is installed.

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 each having a predetermined number of pin holes at both ends 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 superimposed and a portion (one end, two ends, 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 having pin holes at a specified pitch on both ends, and prepare the folded form, and then create multiple forms created in this way. While pulling out the pieces, overlap them (collate),
A method of crimping one or both ends is known.

The conventional collating device used in this method, as shown in FIG. tension applying bar 3 and pin wheel 4.

A first pin tractor 5 transports a plurality of stacked forms 1 via a pin wheel 4, a receiver disposed downstream thereof includes a crimping device 6 consisting of a roll 7 and a crimping roll 8, and a second pin for feeding. It has a tractor 9, etc., and the pin wheel 4 pulls out the form 1 set on each form holder 2 through the tension applying bar 3, and overlaps the forms 1 one after another with each pin wheel 4, and then 1 overlaps each other. The first pin tractor 5 sends all the formed forms 1 to a crimping device 6, and the crimping device 6 presses the pressure-sensitive adhesive that has been applied in advance near one or both side edges of each form 1. , the foams were glued together, and then the second pin tractor 9 sent the glued foams downstream. Note that a cutting device and a stacker (not shown) are provided downstream of the second pin tractor 9 to cut the bonded foam into a predetermined size and stack them.

By the way, in the conventional collating device, in order to achieve good sealing and crimping with the crimping device W6, the distance between the first pin tractor 5 and the second pin tractor 9 is set to an integral multiple of the groove of the bottle hole in the form. It was configured so that the form 1 traveling between the first pin tractor 5 and the second pin tractor 9 would have a slight slack.

[Problem to be solved by the invention]

However, in such conventional devices, the plurality of forms being conveyed by the first pin tractor 5 are separated by each pin hole engaging a bin of the pin tractor 5.

Although the longitudinal and widthwise positions between the plurality of forms are regulated, when sent out from the first pin tractor 5,
The restraint by the bottle is released, and the first pin tractor 5
Since the forms of the second pin tractor 9 are slightly slack, there is a problem that a plurality of forms come apart and their positions in the width direction shift. That is, the plurality of forms 1 after leaving the first pin tractor 5 are located at the center in the width direction, as can be clearly seen from FIG. 6, which shows the plurality of forms 1 viewed in the direction of the arrow in FIG. Part 1 is exciting
Both ends tend to sag, and such curvature occurs unevenly across the forms, causing the side edges of one or more of the forms to shift in the width direction, and in this state, for example, one end of the form Since the position indicated by the line B-B has to be glued using the crimping device, there is a problem in that the form ends up being glued with a deviation in the width direction, and if the deviation becomes large, it may result in poor adhesion. Ta.

In order to prevent this, as shown in FIGS. 7 and 8, at an intermediate position between the first pin tractor 5 and the second pin tractor 9,
A device is known in which a presser guide 10 is provided to press the intermediate portion of the form 1 in the width direction from above. however,
The height of the curvature that occurs in the form 1 varies depending on the number of stacked forms, the amount of expansion and contraction of the form, the paper thickness, the paper quality, etc., and the mounting height h of the presser guide 10 depends on the height of the curvature that occurs in the form Since the mounting height of the presser foot guide 10 must be determined accurately in accordance with each form, the mounting height of the presser foot guide 10 must be delicately adjusted depending on each form, and this adjustment is extremely difficult.

The present invention has been made in view of such problems, and provides a collating device that can minimize the occurrence of deviation in the width direction of the form between the first pin tractor and the second pin tractor. The purpose is to

[Means to solve the problem]

The present invention, which has been made to achieve such an object, includes: a first pin tractor that conveys a plurality of forms in a stacked state; a crimping device that presses and presses the plurality of forms sent out from the first pin tractor; A second pin tractor disposed downstream of the crimping device provides resistance to the form supplied to the second pin tractor, and provides resistance to the form passing between the first pin tractor and the second pin tractor when viewed from the side. The gist of the present invention is to provide a collating device having a presser guide that curves upward in a convex shape in a state.

[Effect]

In the collating device having the above configuration, the presser guide provides resistance at the second pin tractor to the plurality of forms that exit the first pin tractor and are fed into the second pin tractor, thereby creating two
The form is curved upward in a convex shape when viewed from the side, and the vehicle travels while maintaining this convex curve. As a result, the travel path of the first form is stabilized, and the convex curvature when viewed from the side gives stiffness to the form, so that each form does not curve in the width direction. In this way, deviations in the width direction of the plurality of forms are kept to a minimum, and bonding is performed with little deviation.

〔Example〕

FIG. 1 is a schematic sectional view of essential parts of a collating device according to an embodiment of the present invention, and FIG. 2 is a plan view thereof. In FIGS. 1 and 2, reference numeral 11 denotes a foam, and pin holes 11a are formed at both ends of the foam with a predetermined pinch. A first pin tractor 22 transports a plurality of forms 11 in a stacked state, and is equipped with a bin 22a to be inserted into a pin hole of the form 11. 23 is a guide plate arranged above the first pin tractor 22, and is provided with a groove 23a through which the bin 22a of the pin tractor 22 passes. A lower guide plate 24 is disposed between the first pin tractors 22 disposed on both side edges of the form and guides the lower surface of the form 11. Upstream of the pin tractor 22, there are a plurality of form supply parts (for example, a form mounting table) that supply a plurality of forms, a means for drawing out a plurality of forms from the plurality of form supply parts and superimposing them, etc. (not shown). is provided.

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. Crimping roll 28
2 is provided corresponding to the illumination position of the pressure sensitive adhesive applied near the side edge of the foam 11 passing through.
Protrusions 28a for crimping are provided on the circumferential surface at appropriate intervals.

With this configuration, the receiver can point-bond the plurality of foams 11 passing between the roll 27 and the pressure roll 28 to each other. Note that although this embodiment shows the case where the foam 11 is bonded near one side edge, the bonding position of the foam 11 is not limited to this case, and may be arbitrarily selected such as near both side edges or the center. The pressure roll may be placed at

The crimped foam 11 is further downstream of the crimping device 26.
A second pin tractor 30 for discharging the second pin tractor 30 and a guide plate 31 arranged above the pin tractor 30 are provided. The distance between the second pin tractor 30 and the upstream first pin tractor 22 is set to be slightly shorter than an integral multiple of the pitch of the bottle holes of the form. There is a slight slack in the form 11 in between. Further, a lower guide plate 32 for guiding the lower surface of the foam and a presser guide 33 located above the foam are provided between the second pin tractors 30 disposed on both side edges of the foam. This presser guide 33 has an upwardly inclined guide portion 33a and a bending portion 33b continuing therefrom at its tip.
This bent portion 33b contacts the passing form 11 and provides resistance, causing the form 11 passing between the first pin tractor 22 and the second pin tractor 30 to move upward, as shown exaggeratedly in FIG. It is installed in a curved manner.

Here, in order to stably curve the form II upward, the bending part 33b of the presser guide 33 should be moved to the position where the form 11 starts to be driven by the second pin tractor 30 (that is, the bins of the second pin tractors 30 on both sides are form 11
It is preferable to place it on the line connecting the position where it starts to be inserted into the pin hole. Note that the mounting height of the bent portion 33b is as follows.

Since the bending portion 33b can be set so as to provide a resistance to the extent that it comes into contact with the passing foam 11, there is no need to change it much even if the number of sheets of the foam, the paper quality, the amount of slack, etc. change. There is no need to make subtle adjustments. In FIGS. 1 and 2, 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 FIG.

Although not shown in the drawings, downstream of the pin tractor 30, there is provided a device for cutting the bonded foam into a predetermined size and removing unnecessary pin hole portions, and a stuffing force for accumulating the cut foam. It is being 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 FIGS. 1 and 2, a plurality of foams are conveyed by a first pin tractor 22 in a stacked state. At this time, on the pin tractor 22, the pin hole 11a of each form 11 is engaged with the pin 22a of the pin tractor 22, and the pin hole 11a of each form 11 is engaged with the pin 22a of the pin tractor 22.
The foam 11 is being conveyed by the movement of 2a. A plurality of forms 1 sent out from the first pin tractor 22
1 is then connected to the crimping device 2 downstream of the first pin tractor 22.
6, the bonded foam 11 is sent by a second pin tractor 30, and downstream thereof is cut into a predetermined size and stacked.

Here, the plurality of forms 11 discharged from the first pin tractor 22 become free by being released from the restraint by the bin 22a of the first pin tractor 22.

As explained in the prior art, due to the inclusion of air during running, the central part tends to bulge and the two side edges sag, which tends to cause lateral deviation.However, in this embodiment, the downstream side Since the presser guide 33 is provided at the second pin tractor 30, this presser guide 33
gives appropriate resistance to the foams 11, causing the plurality of foams 11 to take a stable running path convexly curved upward when viewed from the side as shown in FIG. By passing the form 11 in a convexly curved manner in this way,
The foam 11 is stabilized, and the foam 11 can be kept flat in the width direction as shown in FIG.

For this reason,? J number of foams 11 are pressed by the crimping device 26 with little deviation in the width direction.

The presser guide 33 used in the above embodiment is different from the conventional presser guide 10 (see FIGS. 7 and 8) that presses down the foam that is about to rise, but simply provides a slight resistance to the foam. Since the upstream form is curved into a convex shape, there is no need to make delicate adjustments to the installation height, and there is no need to make adjustments each time depending on the number of forms used or the state of expansion/contraction. do not have. Therefore, the mounting structure can be simplified, and the mounting adjustment is also extremely simple.

In the above embodiment, the presser guide 33 has a plate shape, but the presser guide 33 is not limited to this shape, and may have another shape, such as a rod.

〔Effect of the invention〕

As described above, the present invention has a simple configuration in which a presser guide is provided that provides resistance at the second pin tractor to a plurality of forms sent from the first pin tractor to the second pin tractor, and the plurality of forms are sent from the first pin tractor to the second pin tractor. The form that runs on the pin tractor can be curved in a convex shape when viewed from the side, and this allows each form to be stable, keep it flat in two width directions, and prevent it from shifting in the third width direction. In addition, there is almost no need to adjust the mounting height of the presser guide according to conditions such as the number of sheets, the paper type, the amount of expansion and contraction, etc., and the mounting structure and mounting adjustment can be made extremely simple. It has this effect.
