Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collating apparatus for laminating a plurality of long foams having pin holes of a predetermined pitch at both ends and crimping them together.

2. Description of the Related Art Conventionally, a form spelling is used in which a plurality of forms on which different contents are recorded or printed are overlapped and a part (one end, both ends, etc.) is adhered. As one method of manufacturing this form spelling, a predetermined form is recorded or printed on a long form having pin holes of a predetermined pitch at both ends, a folded form is prepared, and a plurality of forms prepared in this way are prepared. There is known a method of overlapping (collating) while pulling out and crimping one end or both ends thereof.

As shown in FIG. 5, the conventional collating apparatus used in this method includes a plurality of form tables 2 on which a folded form 1 is placed, and a plurality of form tables 2 arranged above each form table 2. A tension applying bar 3 and a pin wheel 4, a first pin tractor 5 for transporting a plurality of foams 1 stacked via the pin wheel 4, and a receiving roll 7 and a pressure roll 8 disposed downstream thereof. It has a crimping device 6 and a second pin tractor 9 for sending out. The pin wheel 4 pulls out the foam 1 set on each foam table 2 through the tension applying bar 3, and forms 1 are successively superimposed, and thereafter, all the superimposed foams 1 are sent to the crimping device 6 by the first pin tractor 5, and the crimping device 6 is pre-applied near one or both side edges of each form 1. Over pressure sensitive adhesive By pressing, bonding the foam to each other, then the second pin tractor 9 had sent out form that is adhered to the downstream. A cutting device and a stacker (not shown) are provided downstream of the second pin tractor 9.
The bonded foam is cut into a predetermined size and stacked.

By the way, in the conventional collating device, usually, in order to perform good crimping with the crimping device 6, the interval between the first pin tractor 5 and the second pin tractor 9 is slightly larger than an integral multiple of the pitch of the pin holes of the foam. The length of the foam 1 is set short so that the foam 1 traveling between the first pin tractor 5 and the second pin tractor 9 has a slight slack.

[Problems to be solved by the invention]

However, in such a conventional device, the plurality of foams being conveyed by the first pin tractor 5 are positioned in the longitudinal and width directions between the plurality of foams by the pin holes engaging the pins of the pin tractor 5. However, when sent out from the first pin tractor 5, the restraint by the pins is released, and the first pin tractor 5 and the second pin tractor 9 are slightly slackened. There has been a problem that the position is displaced and the position in the width direction is shifted. That is, the plurality of foams 1 after leaving the first pin tractor 5 are positioned at the center in the width direction as can be clearly seen from FIG. 6, which shows the plurality of foams 1 as viewed in the direction of arrow A in FIG. Parts tend to bulge and both ends hang down, and such curvature occurs unevenly for a plurality of foams, so that the side edges of the plurality of foams are shifted in the width direction.
For example, since the position indicated by the line BB at one end of the foam is bonded by a crimping device, the foam is eventually bonded in a state of being shifted in the width direction, and if the shift is large, poor bonding may occur. There was a problem.

In order to prevent this, as shown in FIGS. 7 and 8, at a position intermediate between the first pin tractor 5 and the second pin tractor 9, a pressing guide 10 for pressing an intermediate portion in the width direction of the foam 1 from above is provided. What is provided is known. However, the height of the curvature generated in the foam 1 varies depending on the number of stacked foams, the amount of expansion and contraction of the foam, the paper thickness, the paper quality, and the like.
Since it is necessary to accurately determine the height corresponding to the height of the curve generated in the above, the mounting height of the presser guide 10 must be finely adjusted according to each form, and the adjustment is extremely difficult.

The present invention has been made in view of such a problem, and provides a collating device capable of minimizing the occurrence of a displacement in the width direction of a foam between a first pin tractor and a second pin tractor. The purpose is to:

[Means for solving the problem]

In order to achieve the above object, the present invention provides a first pin tractor that conveys a plurality of foams in a stacked state, a crimping device that presses a plurality of foams sent from the first pin tractor and crimps them together. , A second pin tractor disposed downstream of the crimping device, and a foam provided between the first pin tractor and the second pin tractor for providing resistance to the foam supplied to the second pin tractor, viewed from the side. The present invention provides a collating device having a pressing guide that gives a convexly curved shape in an upright state.

[Action]

In the collating device having the above configuration, the plurality of foams that exit the first pin tractor and are fed into the second pin tractor are provided with resistance at the second pin tractor, so that the foam is viewed from the side. In this state, a convex curve is given upward, and the vehicle travels while maintaining the convex curve. For this reason, the running path of the foam is stabilized, and the foam is given a stiffness due to the convex curvature when viewed from the side, and each foam does not bend in the width direction. Thus,
The displacement in the width direction of the plurality of foams is kept to a minimum, and the bonding is performed with little displacement.

〔Example〕

FIG. 1 is a schematic sectional view of a main part of a collating apparatus according to an embodiment of the present invention, and FIG. 2 is a plan view thereof. 1 and 2, reference numeral 11 denotes a foam, and pin holes 11a are formed at both ends thereof at a predetermined pitch. 22 has multiple forms 11
This is a first pin tractor that conveys the sheets in a stacked state, and includes a pin 22a that is inserted into a pin hole of the foam 11. Reference numeral 23 denotes a guide plate disposed above the first pin tractor 22, and has a groove 23a through which the pin 22a of the pin tractor 22 passes. Reference numeral 24 denotes a lower guide plate disposed between the first pin tractors 22 disposed on both side edges of the foam and guiding the lower surface of the foam 11. Upstream of the pin tractor 22, a plurality of foam supply units (for example, a foam table) for supplying a plurality of foams, a unit for drawing out a plurality of foams from the plurality of foam supply units and stacking them (not shown), etc. Is provided.

Reference numeral 26 denotes a crimping device arranged downstream of the pin tractor 22, and includes a receiving roll 27 arranged below and a crimping roll 28 arranged thereon. The pressure roll 28 is provided corresponding to the passage position of the pressure-sensitive adhesive applied near the side edge of the foam 11 passing therethrough, and is provided with protrusions 28a for pressure bonding at appropriate intervals on the peripheral surface. With this configuration,
A plurality of foams 11 passing between the receiving roll 27 and the pressure roll 28 can be point-bonded to each other. In the present embodiment, the case where the vicinity of one side edge of the foam 11 is bonded is shown. However, the bonding position of the foam is not limited to this case, and it is arbitrary such as the vicinity of both side edges or the center.
What is necessary is just to arrange | position a pressure roll at each adhesion | attachment position.

Downstream of the crimping device 26, a second pin tractor 30 for discharging the crimped form 11 and a guide plate 31 disposed 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 pin holes of the foam. Form 11 in between has a slight slack. Further, between the second pin tractors 30 arranged on both side edges of the foam, a lower guide plate 32 for guiding the lower surface of the foam and a pressing guide 33 arranged above the foam are provided. The presser guide 33 has a guide portion 33a inclined upward and a bent portion 33b following the guide portion at the end thereof, and a foam through which the bent portion 33b passes.
11 to provide resistance and, as shown exaggeratedly in FIG. 3, mounted so that the foam 11 passing between the first pin tractor 22 and the second pin tractor 30 is curved upward. . Here, in order to bend the foam 11 upward stably, the bent portion 33b of the pressing guide 33 is moved to the position where the foam 11 starts to be driven by the second pin tractor 30 (that is, the pin of the second pin tractor 30 on both sides). Is preferably arranged on a line connecting the positions at which insertion into the pin holes of the form 11 is started). The mounting height of the bent portion 33b may be determined so that the bent portion 33b can contact the foam 11 passing therethrough and give a certain resistance. Therefore, the number of foams, paper quality, and the amount of slackness are set. It does not need to be changed much if it changes, so there is no need to make subtle adjustments. First
In Fig. 2 and Fig. 2, the presser guide 33 has a support shaft at the rear end.
34, and can be pivoted upward from the illustrated operating position.

Downstream of the pin tractor 30, although not shown, there are provided a device for cutting the bonded foam into a predetermined size and removing unnecessary pin hole portions, and a stacker for accumulating the cut foam. Have been. Instead of providing a cutting device and a stacker, a device for simply folding and accumulating the bonded foam may be provided.

 Next, a collating operation performed by the above-described apparatus will be described.

In FIGS. 1 and 2, a plurality of forms are conveyed by the 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 form 11 is conveyed by the movement of the pin 22a. First pin tractor 22
The plurality of foams 11 sent out from the above are then point-bonded by the crimping device 26 downstream of the first pin tractor 22, and the bonded foam 11 is sent by the second pin tractor 30 and has a predetermined size downstream thereof. Disconnected and stacked.

Here, the plurality of foams 11 discharged from the first pin tractor 22 become free when the restraint of the first pin tractor 22 by the pin 22a is released, and contain air during traveling, so that the conventional technique is used. As explained,
There is a tendency for the central part to swell and for the sides to hang down.
Displacement is likely to occur in the lateral direction. However, in this embodiment, since the pressing guide 33 is provided at the second pin tractor 30 on the downstream side, the pressing guide 33 gives an appropriate resistance to the foam 11, and as shown in FIG. When the form 11 is viewed from the side, a stable traveling path curved upward and convex is provided. In this way, the form 11 passes while bending in a convex shape, so that the form 11 can be seated,
As shown in FIG. 4, the foam 11 can be kept flat in the width direction. For this reason, the plurality of foams 11 are hardly shifted in the width direction, and are bonded by the crimping device 26 in a state where the shift in the width direction is small.

The presser guide 33 used in the above embodiment is different from the conventional presser guide 10 (see FIGS. 7 and 8) in that it presses a foam that is going to swell, but merely gives a slight resistance to the foam. Since the upstream foam is convexly curved, there is no need to make fine adjustments to the mounting height, and it is not necessary to adjust each time according to the number of foams to be used or the state of expansion and contraction. . Therefore, the mounting structure can be simplified, and the mounting adjustment is extremely simple.

In the above embodiment, a plate-like guide is shown as the presser guide 33, but the presser guide 33 is not limited to this shape, and may have another shape, for example, a rod shape.

〔The invention's effect〕

As described above, the present invention is simple in that a plurality of foams sent from the first pin tractor to the second pin tractor are provided with a pressing guide that gives resistance at the second pin tractor to the plurality of foams sent to the second pin tractor. With this configuration, the foam running from the first pin tractor to the second pin tractor can be formed into a convexly curved shape when viewed from the side, so that each foam can be seated, Can be kept flat to prevent displacement in the width direction, and its holding guide requires almost no adjustment of the mounting height according to conditions such as the number of foams, paper quality, paper thickness, and expansion / contraction. This has the effect that the structure, mounting adjustment and the like can be extremely simplified.
