Description

[Detailed description of the invention] (Field of industrial application) The present invention is a gluing device for a paper laminating machine that polymerizes and adheres the cover of printed paper or sheets, etc., to a mount such as cardboard or corrugated paper. Regarding the improvement of

(Prior art) Conventionally, this type of interleaving machine was manufactured by Jikosho, for example.
The one disclosed in Publication No. 56-648 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 composed of a gluing device for gluing the cover paper to the backing paper, and a pasting device that superimposes and pastes the cover that has passed through the cover paper feeding device at regular intervals and the backing paper that has passed through the gluing device. .

As a gluing device used in such a paper interleaving machine, for example, the one disclosed in Japanese Utility Model Publication No. 8699/1983 is known.

This consists of a glue roll, a glue transfer roll, a water washing roll, a water roll, a water draining roll, a water washing tank, etc., and the glue stored in the upper part between the glue roll and the glue transfer roll comes out from the gap between the two rolls to a predetermined position. The glue is formed on the glue transfer roll by the same thickness as the glue transfer roll, and this glue is transferred and applied onto the upper surface of the mount paper that is fed between the glue transfer roll and the water washing roll.

When the backing paper is broken, the glue from the glue transfer roll will adhere to the washing roll, but since the washing roll is in contact with the water roll soaked in the washing tank, it will not be washed by the impregnated water. At the same time, this washing water is also removed to the washing tank by the drain roll, so that the washing roll is always in contact with the mount in a dry state.

However, even if the glue used in this type of paper laminating machine is quick-drying, it still contains a relatively large amount of water, so it takes a long time for the glue to dry completely after passing through the paper laminating machine. As time went on, the cover side shrank and the entire surface became distorted into a 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 straightening, 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 pressurized straightening work is problematic because it takes 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 gluing device for a paper interleaving machine which eliminates distortion of a pasted product without requiring much effort and time.

(Means for Solving the Problems) The gluing device of the interleaving paper machine of the present invention has a glue transfer roll that contacts the top surface of the mount and transfers a predetermined amount of glue, and a glue transfer roll that can be viewed from a distance. A glue amount adjustment roll is provided to adjust the amount of glue to be transferred, and a glue transfer roll is provided below the glue transfer roll to contact the bottom surface of the mount and transfer a predetermined amount of water, and to remove residual water that was not transferred when the mount is interrupted. There is a water transfer roll on which the glue from the glue transfer roll is adhered, a glue remover that removes residual water and glue adhering to the water transfer roll, and a glue remover installed below the water transfer roll to store water. a water tank, a water roll that applies water to the water transfer roll that has been immersed in water in the water tank and from which residual water and glue have been removed by a glue remover; The feature lies in that it is composed of a water amount adjustment roll that adjusts the amount of water applied to the water application roll.

In other words, the gluing device of the conventional interleaving machine is configured to have a watering function.

(Function) A predetermined glue is applied to the upper surface of the mount by a glue transfer roll, and a predetermined amount of water is applied to the lower surface of the mount by a water transfer roll.

Such a mount is sent to a bonding device, and a cover is superimposed and bonded thereon.

Moisture in the glue applied to the top surface of the mount permeates toward the bottom surface, and moisture from water applied to the bottom surface of the mount permeates toward the top 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 laminating device, the cover is relatively thin, so water reaches the top surface, and although the mount is relatively thicker than the cover, moisture permeates from both the top and bottom sides, so the entire pasted product 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.

FIG. 1 is a schematic diagram showing the structure of a paper interleaving machine equipped with a gluing device according to an embodiment of the present invention. FIG. 2 is an enlarged view showing the vicinity of the gluing device.

The interleaving machine 1 includes an upper cover sheet feeding device 2 for feeding the cover sheet A cut into a predetermined size, and an upper cover sheet feeding device 3 for conveying the cover sheet A at regular intervals. , a lower mount feeder 4 for supplying mount B cut to a predetermined size, and a lower mount regular timer for conveying the mount B at regular intervals in synchronization with the cover regular interval feeding device 3. An interval sheet feeding device 5, a gluing device 6 provided after this for gluing the backing paper B, and a cover A that has passed through the cover paper feeding device 3 at regular intervals and a backing sheet B that has passed through the gluing device 6. It is composed of a bonding device 7 that performs polymerization and bonding.

The gluing device 6 applied to such a paper interleaving machine 1 includes a glue transfer roll 8, a glue amount adjustment roll 9, a water transfer roll 10, a glue removal body 11, a water tank 12,
Its main parts are composed of a water application roll 13 and a water amount adjustment roll 14.

The glue transfer roll 8 comes into contact with the upper surface of the mount B to transfer a predetermined amount of glue, and a steel roll or the like is used.

The glue amount adjusting roll 9 is provided so as to be movable toward and away from the glue transfer roll 8 to adjust the amount of glue to be transferred, and is made of steel or the like.

Glue 15 is stored in the upper part between the glue transfer roll 8 and the glue amount adjustment roll 9, and by moving the glue amount adjustment roll 9 near and far, the gap between the glue transfer roll 8 and the glue transfer roll 8 can be adjusted. The thickness of the glue that comes out of the gap and is formed on the outer surface of the glue transfer roll 8 can be varied.

The water transfer roll 10 is provided below the glue transfer roll 8 and comes into contact with the lower surface of the mount B, and is made of steel or the like.

The glue removing body 11 removes glue adhering to the water transfer roll 10, and in this example, a steel plate is brought into contact with the outer periphery of the water transfer roll 10.

The water tank 12 is provided below the water transfer roll 10 and stores water, and the water is replaced with clean water by a circulation device (not shown).

The water application roll 13 is used to apply water to the water transfer roll 10 which has been immersed in water in the water tank 12 and from which the glue has been removed by the glue remover 11, and is made of sponge or the like.

The water amount adjusting roll 14 is provided so as to be movable toward and away from the water transfer roll 10 to adjust the amount of water attached to the water application roll 13, and is made of a rubber roll or the like.

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

Cover A fed one by one from the cover paper feeder 2
are sent to the pasting device 7 at a timing determined by the cover paper feeding device 3 at regular intervals.

On the other hand, the mount B supplied one by one from the mount feeding device 4 is sent to the gluing device 6 at a timing determined by the mount regular interval feeding device 5.

A predetermined amount of glue is applied to the upper surface of the mount B sent to the gluing device 6 by a glue transfer roll 8.

At the same time, a predetermined amount of water is applied to the lower surface of the mount B by the water transfer roll 10 and sent to the bonding device 7.

The cover sheet A and the mount sheet B fed to the laminating device 7 are gradually overlapped and laminated together to form a laminate C which is then discharged.

The moisture in the glue applied to the top surface of the mount B permeates toward the bottom surface, and the moisture in the glue applied to the bottom surface of the mount B permeates toward the top surface.

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.

In the pasted product C after interleaving, since the cover A is relatively thin, water reaches the top surface, and the backing paper B is relatively thicker than the cover A, but water permeates from both the top and bottom sides of the pasted paper. As for material C, the entire surface 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 applied to 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 shape.

In order to vary the amount of water applied to the lower surface of the mount B, the water amount adjustment roll 1 is used for the water transfer roll 10.
This can be done by moving 4 near and far.

When the mount B is interrupted, water that has not been transferred to the lower surface of the mount B remains on the water transfer roll 10, and the glue from the glue transfer roll 8 is adhered onto this remaining water.

The remaining water and glue attached to the water transfer roll 10 are
The adhesive is removed by the adhesive remover 11.

At this time, since the glue is indirectly attached to the water transfer roll 10 via the residual water, it is easily removed.

The water transfer roll 10 that has passed through the glue remover 11 is coated with new water from the water tank 12 by the water application roll 12, and this is adjusted to a predetermined amount by the water amount adjustment roll 14 and is applied to the bottom surface of the mount B. applied.

In the previous embodiment, the glue removing body 11 was tilted so that the end in contact with the water transfer roll 10 was raised, but the present invention is not limited to this. For example, the adhesive removal body 11 may be tilted so that the end in contact with the water transfer roll 10 is lowered.

In the previous embodiment, the glue removing body 11 is made of a steel plate that is brought into contact with the water transfer roll 10, but the present invention is not limited to this, and may be a fluid such as water sprayed from a nozzle.

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

(1) Since an appropriate amount of water is applied to the bottom surface of the mount, distortion of the laminate can be eliminated without much effort and time.

(2) The structure is extremely simple because it is possible to apply an appropriate amount of water to the bottom surface of the mount by simply modifying the conventional gluing device.

(3) Since it is only necessary to slightly modify the conventional gluing device, it can be applied to existing interleaving machines extremely easily.

(4) Since glue and water are applied to the mount at the same time, it is easy to adjust the amount of water required to remove distortion of the bonded product.

(5) Water is used to eliminate distortion of the bonded material, so running costs are low.

(6) When glue adheres to the water transfer roll, there is a predetermined amount of water in front of it, so it can be easily removed using a glue remover.
