Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in a paper laminating machine that polymerizes and adheres the cover of stamp paper, sheets, etc., and the backing paper, such as cardboard or cardboard.

(Prior art) Conventionally, this type of interleaving machine was manufactured by Jikosho, for example.
The one disclosed in Japanese Patent No. 56-6480 is known.

This consists of an upper cover sheet feeding device for supplying covers cut to a predetermined size, an upper cover sheet feeding device for feeding covers at regular intervals, and a cover sheet feeding device for feeding covers cut to a predetermined size at regular intervals. A lower mount paper feeding device for feeding the mount paper, a lower mount paper feeding device at fixed intervals for transporting the mount paper at regular intervals in synchronization with the cover fixed interval paper feeding device, and a lower mount paper feeding device provided at the subsequent stage thereof. The main parts are comprised of a gluing device for gluing the pasted mount, and a pasting device for superimposing and pasting the cover that has passed through the cover sheet feeding device at regular intervals and the backing sheet that has passed through the gluing device. There is.

However, such paper-sheet machines apply glue to the top surface of the backing paper and then polymerize and stick the cover on top of this, but even if the glue used is quick-drying, there are relatively many problems. Due to the moisture content, the pasted material that had passed through the interleaving machine would shrink on the cover side as the glue dried completely, resulting in an overall distorted concave spherical shape.

Therefore, as it is, it lacks straightness and cannot be subjected to subsequent processing such as cutting.

For this reason, in the past, a set of several dozen laminated sheets was turned over alternately, the front and back sides were turned over, and then they were polymerized and pressed using a press for, for example, over a day to correct the distortion. After correction, it is returned to its original state by turning the front and back sides again, and the next processing is performed with the front and back sides of each bonded product aligned.

However, such pressure straightening work is problematic because it requires a lot of effort and time, and improvements have been desired.

(Problems that the invention attempts to solve) This invention was created in view of the problems mentioned above and to solve them, and its purpose is to:
To provide a paper interleaving machine which eliminates distortion of a pasted product without much effort and time.

(Means for Solving the Problems) The interleaving machine of the present invention includes an upper cover sheet feeder for feeding covers cut into predetermined dimensions, and an upper cover feeder for feeding the covers at regular intervals. A cover sheet feeding device at regular intervals, a lower sheet feeding device for feeding mounts cut to predetermined dimensions, and a subsequent mount sheet feeding device at regular intervals in synchronization with the cover sheet feeding device at regular intervals. A lower mount regular interval feeding device, a gluing device provided after this for gluing the mount, and a cover that has passed through the cover regular interval feeding device and the mount that has passed through the gluing device are superimposed. A paper laminating machine equipped with a laminating device for pasting is characterized in that a water application device is installed next to the pasting device to apply an appropriate amount of water to the lower surface of the mount after pasting. Exists.

In other words, it is a conventional interleaving machine with a watering device added.

(Function) Gluing is applied to the upper surface of the mount by a gluing device, and a cover is superimposed and laminated on this upper surface by a laminating device.

An appropriate amount of water is applied to the lower surface of the mount of the pasted product by a water applicator after passing through the pasting device.

When the moisture in the glue applied to the upper surface of the mount permeates toward the lower surface, the moisture in the water applied to the lower surface of the mount after lamination permeates toward the upper surface.

On the other hand, the adhesive from the upper surface of the mount is attached to the lower surface of the cover when it is bonded to the mount, and the moisture from this glue permeates toward the upper surface.

After passing through the water-applying device, the cover is relatively thin, so moisture reaches the top surface, and although the backing paper is relatively thicker than the cover, water permeates from both the top and bottom sides, so the entire laminate is It becomes uniformly moist, and from this state the water evaporates and dries.

Therefore, the shrinkage rates of the upper and lower surfaces of the bonded product are equal, and there is no distortion.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

It is equipped with an endless chain 10 that is stretched around and rotates in a predetermined direction, and an attachment 11 attached to a part of the chain 10, and is attached to the rear end of the cover A fed from the cover sheet feeder 2. The attachment 11 is brought into contact with the attachment 11 and is pressed to transfer the attachment.

The mount feeder 4 is located at a lower level and is used to feed mounts B, such as cardboard or corrugated paper, cut into predetermined dimensions one by one.

The mount regular interval feeding device 5 is located at a lower level and is provided at the next stage of the mount feeding device 4, and is for conveying the mount B at regular intervals in synchronization with the cover regular interval feeding device 3. , similar to the cover regular interval paper feeding device 3,
Sprocket 12, chain 13, attachment 14
It consists of.

The gluing device 6 is provided next to the mount paper feeding device 5 at regular intervals, and is used to apply glue to the upper surface of the mount B, and includes a glue transfer roll 15, a glue amount adjustment roll 16, a pressure roll 17, etc. ing.

The pasting device 7 is for superimposing and pasting the cover A that has passed through the cover paper feeding device 3 at regular intervals and the mount B that has passed through the gluing device 6, and is composed of a pair of upper and lower pasting rolls 18. ing.

The water application device 8 is provided at the next stage of the laminating device 7,
An appropriate amount of water is applied to the lower surface of the mount B after lamination.

In this example, water tank 1 stores a predetermined amount of water.
9, a water-applied roll 20 made of sponge or the like whose lower part is immersed in water and rotates in a predetermined direction, and a water transfer roll 21 arranged above and joined to the roll.
, a water amount adjustment roll 22 made of rubber or the like which is disposed in front of this and connected to it so that it can be seen from a distance, and a pressure roller made of steel or the like which is arranged above the water transfer roll 21 and is attached to it so that it can be seen from or seen from it. It consists of a roll 23.

A delivery device 24 made of a belt conveyor or the like is provided at the next stage of the water application device 8, and guide plates 25 are provided before and after the water transfer roll 21 of the water application device 8.

In this embodiment, a feeding device 28 consisting of a feeding belt 26 and a feeding roll 27 is interposed between the cover sheet feeding device 2 and the cover sheet feeding device 3 at regular intervals.

Next, the operation will be explained based on such a configuration.

Cover A fed one by one from the cover paper feeder 2
passes through the feeding device 28 to the cover paper feeding device 3 at regular intervals.
It is sent to the bonding device 7 at the appropriate timing.

On the other hand, the mounts B fed one by one from the mount paper feeding device 4 are pasted on the top surface by the gluing device 6 at a timing determined by the mount regular interval feeding device 5, and sent to the pasting device 7. Sent.

The cover A and the mount B sent to the pasting device 7 are gradually polymerized and pasted together to form a pasted product C, which is sent to the water application device 8.

In the water application device 8, an appropriate amount of water is applied to the lower surface of the mount B of the bonded material C by the water transfer roll 21,
Thereafter, it is carried out by the carrying out device 24.

Since the top surface of the mount B is glued by the gluing device 6, the water permeates toward the bottom surface of the mount B.

Moreover, since water is applied to the lower surface of the mount B after pasting by the water application device 8, the water permeates toward the upper surface of the mount B.

On the other hand, when the cover A is attached to the mount B, the glue on the upper surface of the mount B is adhered to the lower surface thereof, so that the water permeates toward the upper surface of the cover A.

Then, in the laminate C after lamination, since cover A is comparatively thin, moisture reaches the upper surface, and although mount B is comparatively thicker than cover A, moisture penetrates from both the top and bottom surfaces, so that the entire laminate C becomes uniformly wet.

As time passes, the moisture in such a bonded material C gradually evaporates and dries out.

At this time, since water is applied to the lower surface of the laminate C, that is, the lower surface of the mount B, and the bottom surface of the mount B is wet, the shrinkage rate of the lower and upper surfaces of the laminate C becomes equal, and the laminate C becomes straight without distortion. Become.

If the thickness of the mount B or the thickness of the cover A changes, the amount of water applied to the lower surface of the mount B is adjusted.

Furthermore, by varying the amount of water placed on the lower surface of the mount B, the bonded material C can be made into a concave spherical shape or a convex spherical shape instead of a straight state.

The amount of water applied to the lower surface of the mount B can be varied by moving the water amount adjustment roll 22 near or far from the water transfer roll 21 of the water applicator 8.

In the previous embodiment, the water application device 8 was composed of the water tank 19, the water application roll 20, the water transfer roll 21, the water amount adjustment roll 22, and the pressure roll 23, but the invention is not limited to this.

For example, the water-applied roll 20 may be omitted and the water transfer roll 21 may be directly immersed in water in the water tank 19.

Further, instead of the water transfer roll 21 rotating in a predetermined direction, a simple water body made of sponge or the like may be used, and this may be brought into sliding contact with the lower surface of the mount B.

Furthermore, a water jet nozzle may be provided, and an appropriate amount of water jetted from the nozzle may be applied to the lower surface of the mount B.

(Effects of the invention) As described above, according to the present invention, the following excellent effects can be achieved.

(1) Since a water application device is installed to apply an appropriate amount of water to the bottom surface of the mount, distortion of the bonded product can be eliminated without much effort and time.

(2) Since the water application device is installed next to the laminating device, it can be applied to existing laminating machines extremely easily.

(3) Since the water application device is installed next to the laminating device, it can be easily inspected and adjusted.

(4) Since water is used, running costs are low.
