Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to an adhesive device for adhering an adhesive material to a part of the surface of continuous paper, and in particular, to an adhesive device for adhering adhesive material to a part of the surface of continuous paper, and in particular, for adhering a single piece of continuous paper from which a postcard is formed. The present invention relates to an adhesive device for bonding a continuous paper formed by a continuous paper and an adhesive material covering secret information on the surface thereof.

(Prior art) In particular, in recent years, there has been an increase in the number of mail items with confidential information written on them, such as notifications of bank account balances. Postcards have been developed that are hidden and are shaped so that the recipient can easily see the contents of the original receipt after receiving it.

As a conventional device for adhering an adhesive material to the surface of a single piece of postcard, there is a device that applies pressure to a pressure-sensitive adhesive layer formed on the back side of the adhesive material onto a single piece of postcard size. Ta.

(Problems to be Solved by the Invention) However, in an apparatus that applies an adhesive material having such a pressure-sensitive adhesive layer formed on the back surface to a part of a single postcard,
In order for the pressure-sensitive adhesive layer of the adhesive to adhere to the surface of a single postcard with slight contact, it is necessary to determine the initial position of the single postcard, even when the tip of the adhesive is not located. There is a high probability that a so-called pasting error will occur, in which the adhesive is not pasted in the correct position.

Moreover, in the case of adhesive materials on which a conventional pressure-sensitive adhesive layer is formed, in order to make the adhesive material peelable from the surface of a single postcard, the surface of the single postcard must be treated with silicone, etc. A peeling process such as this is required. Therefore, it becomes necessary to prepare a separate device for such processing or to incorporate such a mechanism into the adhesive bonding device, which leads to an increase in the manufacturing cost.

Therefore, the main object of the present invention is to provide an adhesive material adhesion device that can affix the adhesive material at an optimal position and that does not require a peeling process or other treatment on the mount side of a single postcard. It is to provide.

(Means for Solving the Problems) The present invention provides a continuous paper transport device that continuously or intermittently feeds continuous paper formed to be splittable into single pieces of appropriate size, and a continuous paper transport device that is thermally bonded to the back surface of the continuous paper transport device. An adhesive material transfer device that sends the adhesive material on which the adhesive resin layer is formed to an appropriate position on the surface of the continuous paper so that it is adhered to the surface of the continuous paper, and an adhesive material that is fed by the adhesive material transfer device. An initial pressure and heating device presses and heats the tip of the material against the surface of the continuous paper, and the adhesive material whose tip is adhered to the surface of the continuous paper by the initial pressure and heating device is used to form a sheet of continuous paper. An adhesive material forming device that forms adhesive material into small pieces that are the same as or smaller than a single piece forming continuous paper, including a planar pressure heating device that performs pressure heating and heating. It is an adhesive device.

(Function) According to the present invention, the continuous paper transport device is configured to feed the continuous paper continuously or intermittently, so that each piece of continuous paper is sequentially moved at appropriate intervals and precisely transport in the direction.

The initial pressure and heating device presses and heats the tip of the adhesive material.

The planar pressure heating device presses and heats the adhesive material in a planar manner on the surface of continuous paper.

The adhesive material forming device cuts the adhesive material into pieces that are the same as or smaller than the single pieces forming the continuous paper.

(Effects of the Invention) According to the present invention, the single pieces forming the continuous paper are sequentially or intermittently transferred in an optimal direction at appropriate intervals in the continuous paper transport device, and the continuous paper is When the tip of the adhesive material is overlapped with a part of the continuous paper and the adhesive material is located at the optimal position, a part of the tip of the adhesive material is pressed against the continuous paper and pressurized by the initial pressure heating device. The entire or part of the adhesive material is heated and then pressurized and heated in a planar pressure heating device to bond the adhesive material within the plane. It is precisely adhered to the optimal position on the surface of continuous paper.

In addition, with the initial pressure heating device and the planar pressure heating device,
Since the adhesive material is configured to melt the heat-adhesive resin layer formed on the back side and adhere to the surface of the continuous paper, the surface of the continuous paper does not require any process such as peeling treatment. First, it is possible to configure the adhesive material to be peeled off only by changing the structure of each part of the heat-adhesive resin layer, that is, by changing the adhesive strength. Therefore, there is no need to incorporate a mechanism necessary for a special peeling process into this adhesive device, and there is no need to separately prepare it.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Example) FIG. 1 is a perspective view showing the entire adhesive device according to the present invention, and FIG. 2A is a plan view showing an example of continuous paper used in this adhesive device.

On the main surface of this heat-adhesive resin layer 20, the adhesion force of this heat-adhesive resin layer 20 is partially reduced to weaken the postcard single piece 1.
An adhesion inhibiting layer 22 to be adhered to 2 is partially formed. The adhesion inhibiting layer 22 is made of a material that exhibits adhesiveness at a higher temperature than the thermoadhesive resin layer 20, or exhibits no adhesiveness at all.

In this embodiment, on the top and bottom sides of the single postcard piece 12, that is, in the vicinity of both ends of the continuous paper 1o on the sprocket hole 14 side, there are partial frames with a certain width where the adhesion inhibiting layer 22 is not formed. Furthermore, on the widthwise side of the continuous paper 10, there is a portion where the adhesion inhibiting layer 22 is not formed so that the thermally adhesive resin layer 2° is exposed in spots at the leading end portion of the covering material 16. Therefore, the portion where the adhesion inhibiting layer 22 is formed is weak, and the adhesion inhibiting layer 22 is weak.

It will be pressed and heated by the pressure heating device 84.

That is, when the covering material 16 whose tip is bonded is located at the lower part (initial upstream position) of the planar pressure and heating device 84, the planar pressure and heating device 84 moves to the adhesive portion transfer table. 4

It is configured to control the transfer of the pressure heating device 80. however,
The continuous paper 10 is formed so as not to move backwards, and is designed to prevent the continuous paper 10 from running backwards in response to the backward movement of the adhesive portion transfer table 48 and the linear pressure heating device 82 and the planar pressure heating device 84 of the pressure heating device 80. It is formed.

In this way, the pressurizing and heating device 80 repeats the cycle of forward movement, consideration point (downstream side), backward movement, and consideration point (upstream side), and as shown in FIG. A covering material 16 is appropriately adhered to the surface of 12.

Then, the continuous paper 10 partially covered with the covering material 16 in this manner is folded as appropriate, then cut off as appropriate, and delivered to a post office.
