Description

[Detailed description of the invention] Industrial application field This invention folds continuous paper while transporting it.
The present invention relates to a continuous paper folding and bonding device for creating stacked adhesive sheets such as cards, postcards, ledgers, envelopes, etc. by continuously bonding their stacked surfaces together.

BACKGROUND TECHNOLOGY This type of conventional continuous paper folding and gluing device applies an adhesive liquid to the overlapping surfaces of the continuous paper, and then passes the continuous paper between a squeeze member consisting of two rollers or bars. , the folding perforations and the like were used as creases to fold and adhere to a desired state (for example, Japanese Patent Laid-Open No. 56-24195).

Problems to be Solved by the Invention However, the above-mentioned conventional technology is susceptible to the effects of accuracy errors during continuous paper manufacturing, such as slow transport speed of continuous paper and misalignment of the setting position of folding perforations. It was difficult to perform an easy and stable folding operation. There was also the problem that the overlapping surfaces of the continuous sheets coated with the adhesive liquid rubbed against each other before they were overlapped in the desired state by the folding operation, making it impossible to perform the folding operation accurately.

For this reason, the prior art has the disadvantage that smooth bonding work is often obstructed, such as wrinkles and jamming.

The object of the present invention is to provide a continuous paper folding and gluing device that eliminates these drawbacks.

Means for solving the problem This invention folds continuous paper while transporting it.
In a device for gluing overlapping surfaces together, there is a coating mechanism for applying an adhesive liquid to the overlapping surfaces of continuous sheets of paper, and a folding sewing machine that applies an adhesive liquid to the overlapping surfaces of continuous sheets of paper, and a folding sewing machine to make the folds of the continuous sheets of paper that have passed through this coating mechanism extend in the conveying direction. A squeezing member consisting of two bars arranged with a gap between each other is provided for folding from the eye, etc. and gluing the overlapping surfaces together, and the squeezing member and the application mechanism are provided on this squeezing member. For example, a pair of opposing guide claws that sandwich the continuous paper with a gap larger than the spacing between the squeeze members so that the overlapped surfaces near the folds of the continuous paper located between the A plate squeeze member is provided.

Function: Before feeding the continuous paper to the squeeze member, the continuous paper is slightly folded by pinching the folded portion of the continuous paper with the temporary squeeze member so that the overlapped surfaces face each other and approach each other. Therefore, the continuous paper can be smoothly fed to the squeeze member, and accurate folding work can be performed.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, this folding adhesive device (hereinafter referred to as the device)

Continuous paper 1 is provided with transparent transport holes 2 along both sides in the width direction so as to extend over the entire length, and at predetermined intervals in the longitudinal direction.
A cutting perforation 4 is provided as a boundary between the unit sheets 3. Furthermore, a folding perforation 5 is provided at the center in the width direction of the continuous paper 1 so as to extend over the entire length, and when the continuous paper 1 is folded using this as a crease, the overlapping surface becomes an adhesive surface 6.

Next, the apparatus 10 will be explained based on FIG. 1 as well.

A mounting table 11 on which the continuous paper 1 is placed in a folded state is movable, and a paper pull-out guide member 12 extending in the horizontal direction is installed at one end thereof. The continuous paper 1 that has been guided and pulled out by the paper drawer guide member 12 is guided by the guide member 13,

Further, it is provided obliquely so as to sandwich the continuous paper 1 from the folding perforation 5 portion which is the folding portion thereof. Further, a bracket 19 is fixed near the lower ends of the squeeze members 17, 18, and a temporary squeeze member 20 is screwed to this bracket 19, and an auxiliary shaft 21 is fixed thereto. This auxiliary shaft 21 includes both squeeze members 17,
18, and is bent downward into an L-shape (see Figures 2 and 4).

As is clear from FIGS. 2 and 3, the temporary squeeze member 20 includes a mounting plate 20a having screw holes for fixing, side plates 20b and 20c fixed to both sides of the mounting plate 20a, and Each side plate 2

Then, when the continuous paper 1 passes between these guide claws 20d and 20e, the continuous paper 1 is arranged so that the overlapping surfaces, that is, the adhesive surfaces 6 located on both sides of the folding perforation 5 come close to each other. The vicinity of the fold perforation 5 of the paper 1 is pinched.

Next, the coating mechanism will be explained based on FIG. The rotating shaft extends parallel to the tension members 15 and 16, and their circumferential surfaces contact each other. The application roller 22 and the pull-out roller 23 are connected to the support plate 2
4 is rotatably supported. The drawing roller 23 is located in a container 25 into which adhesive liquid is supplied from a tank 26 by a pump 27 via a pipe 28 so that the lower part of the drawing roller 23 is wetted. ing. This adhesive liquid may be a liquid such as water, in addition to a normal adhesive, if a rewetting adhesive is used that has been applied to the adhesive surface 6 of the continuous paper 1 in advance. In addition, the pull-out roller 2
The rotating shaft 3 is linked to a preparation drive 29 and a coating drive 30, which are switched and linked by operating a clutch device (not shown). The preparation drive device 29 always applies an appropriate amount of adhesive liquid to the application roller 22 to prevent it from drying when the device 10 is in a preparation state or a paused state and is not conveying the continuous paper 1. In order to do this, the pull-out roller 23 is rotated at a predetermined low speed in response to a signal from the ready switch _S0 . Further, when the device 10 is in operation and the continuous paper 1 is being conveyed, the coating driving device 30 applies an appropriate amount of adhesive liquid to the adhesive surface 6 of the continuous paper 1 being conveyed using the coating roller 22. Therefore, the pull-out roller 23 is rotated so that the peripheral speed of the application roller 22 is approximately the same as the conveyance speed of the continuous paper 1. Both drive devices 29,
30 are linked to the drive device 31 of the main body of the device 10 so as to obtain their rotational driving force from the drive device 31 of the main body of the device 10, respectively. The above-mentioned clutch device is configured to switch the linkage between each drive device 29, 30 and the pull-out roller 23 in response to signals from the conveyance start switch S ₁ and the stop switch ₂ for the continuous paper 1.

Note that the above-described linkage switching may be performed by other known switching means, or each drive device 2 may be
A drive device other than the drive device 31 is provided as a drive source for the application rollers 9 and 30, and this drive device is synchronized with a signal that detects the conveyance state of the continuous paper 1 or the operating state of the main body of the apparatus 10 in the conveyance state. 22 may be driven to rotate in synchronization with the conveyance state of the continuous paper 1, while the coating roller 22 may be driven to rotate at a predetermined low speed when the conveyance of the continuous paper 1 is stopped.

Also, the adhesive surface 6 of the continuous paper 1 is applied to the application roller 22.
A contact member 32 is fixed to a rotary plate 33 so as to be positioned parallel to the application roller 22 in order to bring the contact member into contact with the application roller 22 . Tension members 15 and 16 are also fixed to the rotating plate 33, and a shaft 34 (fourth
It can be rotated freely using the fulcrum (see figure) as a fulcrum. On the other hand, as is clear from FIG. 4, a flexible brush 35 is attached to the contact member 32 via a support shaft 36. As shown in FIG. 4a, when the apparatus 10 is in a stopped state and the ready switch _S0 is in an on state, the contact member 32, together with the tension members 15 and 16, is in a ready state away from the application roller 22. When a start signal is issued by the start switch _S1 of the device 10, the rotating plate 33 rotates as shown in FIG. do. Also, when a stop signal is issued by the stop switch _S2 , the rotating plate 3
3 rotates back to the ready state shown in FIG. 4a. In this ready state, the brush 35 and application roller 22
In order to set the continuous paper 1, it is desirable that the distance between the paper and the paper is 5 cm or more.

Note that the paper drawer guide member 1 shown in FIG.
2 is provided with sensing means such as a micro switch (not shown) for sensing the presence or absence of the continuous paper 1, and this sensing means is connected to a delay circuit (not shown) connected to the rotating plate 33. It constitutes a detection mechanism that rotates the device to the ready state. Then, the rotating plate 33 is adjusted to the ready state just before the end of the continuous paper 1 passes the front surface of the application roller 22 based on the sensing signal from the sensing means.

As is clear from FIG.
A feed guide plate 37 is provided above the paper 8 to facilitate the introduction of the folded continuous paper 1. Following this feed guide plate 37, a tractor 38 having a pin that engages with the transport hole 2 of the continuous paper 1 is provided, and above the tractor 38, the continuous paper 1
A cutter 39 is arranged to cut the marginal portion of the cutter 39 . Following the tractor 38, two pairs of upper and lower low-speed rollers 40 and 41 and two pairs of upper and lower high-speed rollers 42 and 43 are rotatably provided with a blade 44 in between. Then, due to the speed difference between the low and high speed rollers 40, 41, 42, and 43, tension is applied to the cutting perforation 4 of the continuous paper 1, and the blade 44 is brought into contact with the perforation 4, and the continuous paper 1 is The unit paper 3 is torn. Laminated adhesive paper 7 created by cutting
are accumulated on a transfer and accumulation table 45 provided after the high-speed rollers 42 and 43.

In addition, each of the rollers 40, 41, 42, 4 mentioned above
The lower housing portion of No. 3 includes a tractor 38, conveyance-related drives such as the rollers 40, 41, 42, 43, etc.
A control mechanism for controlling the rotation of the application roller 22 and the pull-out roller 23 and the rotation of the rotating plate 33 is built-in. When the sensing means (not shown) provided on the feed guide plate 37 in addition to the aforementioned sensing means (not shown) senses the final end of the continuous paper 1, the unit of the end portion is detected by the sensing signal. Each roller 40, 41, 42, 43 is driven until the paper 3 is carried out from the high speed rollers 42, 43,
It is then configured to stop.

Next, the operation of the above embodiment will be explained.

Necessary information is printed on each unit paper 3 by a printer which is an output device of an electronic computing device, and a paper drawer guide member 1 is provided so that the continuous paper 1 folded in a zigzag manner can be placed on a mounting table 11 and easily pulled out.
2, and pass under the guide members 13 and 14 to each tension member 1 in the state a in FIG. 4.
Insert between 5 and 16. Furthermore, the continuous paper 1 is folded in half at the folding perforation 5, and the guide claws 20b, 20 of the temporary squeezing member 20
In addition, squeeze member 1
7 and 18, and connect the conveyance hole 2 of the continuous paper 1 to the pin of the tractor 38 via the feed guide member 37.
Set. Before and after this setting operation, power is supplied to the device 10 by the ready switch _S0 , and the preparation drive device 29 is driven.
2. Rotate the pull-out roller 23 at low speed.

Next, when the start switch _S1 is turned on, the rotary plate 33 is rotated to the state shown in FIG. Therefore, the adhesive liquid is applied to the adhesive surface 6 of the continuous paper 1 by the application roller 22 as it moves.

When the continuous paper 1 coated with the adhesive liquid passes between the guide claws 20d and 20e of the temporary squeezer 20, it is pinched in the vicinity of the folding perforation 5 as a preliminary operation for folding and adhesive. The surfaces 6 are brought close to each other in advance. Then, when passing between the squeeze members 17 and 18, the folding perforation 5 of the continuous paper 1 is squeezed by the auxiliary shaft 21.
The lower part of the sheet is pushed up, and while preventing the occurrence of wrinkles, the continuous paper 1 is sandwiched from the folding perforation 5 side to the transfer hole 2 side, and as it is sequentially folded, the overlapping surfaces, that is, the adhesive surfaces 6 are adhered to each other. I'm going to go. The continuous paper 1 that has been superimposed and glued in this way passes through the feed guide plate 37, the tractor 38, and the cutter 39, and is cut at the marginal portion, and also has the speed difference between the low and high speed rollers 40, 41, 42, and 43. As a result, the sheet is cut by the blade 44 at the cutting perforation 4, and the overlapping adhesive sheet 7 consisting of the unit sheet 3 is carried out onto the transfer/accumulation table 45.

When the folding and gluing work continues and the continuous paper 1 is no longer on the mounting table 11, the paper pull-out member 12
A sensing means (not shown) installed in the continuous paper 1 operates, and the rotating plate 33 starts rotating just before the coating roller 22 finishes applying the adhesive liquid to the final end of the continuous paper 1.
Subsequently, when the final end is sensed by another sensing means (not shown) provided on the feed guide plate 37,
When the final end passes the high-speed rollers 42, 43, the drive of the tractor 38, low-speed rollers 40, 41, high-speed rollers 42, 43, etc. is stopped, and a ready state is achieved.

In addition, the temporary squeeze member 2 in the above-mentioned embodiment
0 was configured so that the guide claws 20d and 20e sandwiched the vicinity of the folding perforation 5 of the continuous paper 1, but
The temporary squeezing member 20 in the present invention is a continuous paper 1
The configuration is not limited in any way as long as it can be sandwiched so that the overlapping surfaces of the two are close to each other and face each other. If the temporary squeezing member 20 is configured to be movable along the squeezing members 17 and 18, sheets of various sizes can be folded and bonded easily and accurately. Furthermore, the configurations of the coating mechanism, the squeezing member, or the tension member are not limited to the embodiments described above.

Effects of the Invention As is clear from the above explanation, according to the present invention, a temporary squeeze member is used to fold the continuous paper to be folded into a folding perforation in which the overlapping surfaces coated with adhesive liquid form folds. Since the paper is sandwiched in advance so that they approach each other from the sides and a preliminary gentle folding operation is performed, the continuous paper can be smoothly inserted into the squeeze member without the overlapping surfaces coated with adhesive liquid rubbing against each other. Since the folding operation is reliably started from the folding perforation side, the folding operation at the squeeze member can be performed easily and accurately, and the folding perforation of continuous paper can be easily and accurately meandered. Even if the perforation strength and weakness are not as accurate, it prevents wrinkles and jamming of the laminated adhesive paper, and allows easy and accurate folding.
Furthermore, since the squeezing member is composed of two bars, a temporary squeezing member can be provided on the squeezing member, which has the advantage of not only making it easy to set continuous paper but also making it possible to downsize the device. It can be effective.
