Description

  The present invention relates to a pressure-sensitive postcard making apparatus, and more specifically, a pressure-sensitive postcard making apparatus that applies a powder adhesive to a secret information printing surface of a sheet on which secret information is printed, and then presupposes this application and pressure-bonds the assumed surface. About.

Conventionally, in order to transmit character information only to a specific individual, generally, the character description is in a sealed form so that the individual can confirm the character information only after opening.
In recent years, personal information protection has become a strict question, and various business establishments, for example, personal information such as various personal data, gradebooks, salary statements, etc., are printed on the printed part of the written text. It is recorded and distributed in the form of envelopes or cards by bonding or crimping the peripheral edge of the printed part or the entire surface of the written text.

  Among these, postcard-sized cards are called crimped postcards and can be used at the same charge as regular postcards. Therefore, as a printing information concealment system that is highly convenient for information providers, advertising It is also widely used for advertising direct mail.

  In order to use such a printing information concealment system for crimping postcards, etc., secret information has conventionally been created by entrusting it to a specialized manufacturer or introducing an expensive crimping postcard or other manufacturing / printing device. .

  There are two methods for creating confidential information using a manufacturing / printing device such as a crimping postcard, such as a method of applying adhesive after information printing or a method of applying adhesive before information printing. The premise of creating a large amount of information is essential and expensive.

Further, such outsourcing to a manufacturer is not a preferable method for creating confidential information because there is a potential problem of leakage of personal information.
By the way, in recent years, along with the development of personal computers and printers, there has been proposed one that can easily create a crimp postcard even in a small unit so that it can be used by small-scale offices and individuals.

  For example, postcard paper with release paper pre-applied with a pressure sensitive adhesive is on the market. In this method, after printing predetermined character information or the like on the printing surface inside the two-fold, the pressure-sensitive adhesive portion is crimped to complete a postcard for postage.

  For example, a set of adhesive film and postcard paper is sold. In this method, after printing predetermined character information or the like on the printing surface inside the double fold, the adhesive film is pressure-bonded with the adhesive film sandwiched inside the double fold so that a postcard for posting can be created.

  However, this is inevitable, and the handling is cumbersome, and it is better to personally create several crimped postcards, but it is cheap, quick, and responsive to demand in a certain number of units. It can not be created with.

Therefore, a toner-like adhesive composed of microcapsules containing an adhesive is transferred onto the surface of the substrate by electrostatic printing and flash-fixed. During adhesion, the microcapsules are destroyed by pressure and the adhesive in the capsule is leached. In this way, a proposal has been made that it is possible to easily create a pressure-bonded postcard. This proposal also suggests a pulverized toner obtained by melting, kneading, and pulverizing an adhesive. (For example, refer to Patent Document 1.)
In addition, the pressure-bonding substance is put in a replacement printing cartridge for an office printer or copying machine, and the pressure-bonding substance is applied to a government-made postcard or envelope by the same operation as the printing operation by the office printer or copying machine. After that, a proposal has been made that it is applied to a dedicated crimping machine, and up to the crimping dedicated machine can be performed by a single printer or copying machine. In addition, this proposal suggests that a crimping substance is applied to one side of a fold and one side of a center of a fold. (For example, see Patent Document 2.)
In addition, a method has been proposed in which an image is created on demand by an electrophotographic method using toner containing a heat-sensitive adhesive. In this proposal, the softening temperature of the heat-sensitive adhesive is configured to be higher than the softening temperature of the binder resin of the toner for electrophotography, and the ratio of the heat-sensitive adhesive to the toner for electrophotography is 5 to 5. It has been proposed that the composition be 60% by weight and that the composition of the heat-sensitive adhesive contains at least one selected from the group consisting of a heat-adhesive resin, a hot melt, and waxes. (For example, refer to Patent Document 3.)
JP 09-104849 A (paragraphs 0005, 0014, FIG. 1, FIG. 3, FIG. 6) JP 2000-006553 A (summary, no figure) Japanese Patent Laying-Open No. 2004-126231 (paragraphs 0085 to 0087, not shown)

  However, although the technology of Patent Document 1 describes the configuration and composition of the microcapsule toner, the pulverized toner is merely suggested to the extent that it is conceived, and the specific composition, production method, There is no description about the usage, and this makes it possible for even those skilled in the art to produce useful pulverized toners and, of course, not even make prototypes.

  In addition, the technology of Patent Document 2 is to create a print information concealment document by a public postcard or envelope before being applied to a dedicated crimping machine, and it is convenient in that it must be applied to the dedicated crimping machine to complete for posting. It must be said that it is lacking in performance and economy and is far from being responsive to demand.

  Further, in the technique of Patent Document 3, the softening temperature of the heat-sensitive adhesive is merely set higher than the softening temperature of the binder resin of the toner for the electrophotographic method, but it is suggested to the extent of the idea. No specific material formulation or specific usage of toner containing heat sensitive adhesive is disclosed. Moreover, although the electrophotographic system uses electrostatic development, its practical and specific configuration is not disclosed.

In addition, no toner adhesive powder adhesive for postcards has been distributed to the market to date. The pressure-sensitive adhesive for postcards in circulation is only liquid or adhesive sheet.
An object of the present invention is to easily apply powder adhesive to a plurality of types of pressure-sensitive postcard papers having different paper types after establishing a practical powder adhesive manufacturing method in view of the above-described conventional situation.

(Embodiment 3)
By the way, the pressure-sensitive postcard paper is not limited to one type, and paper quality such as thickness and electric resistance value is not uniform. Even papers that fall within the range stipulated by the Postal Code can be classified into at least four stages as paper standards.

  When the paper quality is different, the powder adhesive is applied to the pressure-bonded postcard paper in a uniform process, so that the pressure-bonded postcard paper having a different paper quality cannot obtain a proper pressure-bonding property as a pressure-bonded postcard.

  Accordingly, at least the paper quality of the pressure-sensitive postcard paper is classified into four stages, and the processing related to the application of the powder adhesive is controlled so as to be different for each type classified in the four stages, so that the pressure-sensitive postcard paper having different paper quality is controlled. Even so, it is possible to obtain appropriate crimpability as a crimping postcard. Hereinafter, this will be described as a third embodiment.

  4 (a) to 4 (d) are diagrams showing four types of pressure-bonded postcard paper generally classified. The crimping postcard paper 21 in FIG. 9A is a rough and thin paper, the crimping postcard paper 22 in FIG. 10B is a relatively thin high-quality paper, and the crimping postcard paper 23 in FIG. Indicates a high-quality paper having a normal thickness, and the pressure-sensitive postcard paper 24 in FIG.

  In this example, the transfer bias of the transfer device 13 during application of the powder adhesive and the transferred (applied) powder adhesive are assumed to be applied to the application surface of the pressure-sensitive postcard paper on these four types of pressure-bonded postcard paper. Depending on the four types of pressure-sensitive postcard paper, the heating temperature at the time of the assumed attachment portion and the three-step processing mode of the pressure-bonding temperature at the pressure-bonding portion at the time of pressure-bonding the pressure-bonded postcard that is presumably attached with powder adhesive. The control is divided into four processing modes.

  FIG. 5 is a view showing four processing mode selection buttons arranged on an operation panel (not shown) of the crimping postcard making apparatus 1. As shown in the figure, the four processing mode selection buttons include a “postcard 1” button 25, a “postcard 2” button 26, a “postcard 3” button 27, and a “postcard 4” button 28.

  The “postcard 1” button 25 is a button for selecting a processing mode when the powder adhesive 17 is applied to the pressure-bonded postcard paper 21, and the “postcard 2” button 26 is a powder on the pressure-bonded postcard paper 22. This is a button for selecting a processing mode when the body adhesive 17 is applied. A “postcard 3” button 27 is a button for selecting a processing mode when the powder adhesive 17 is applied to the crimping postcard paper 23. The “postcard 4” button 28 is a button for selecting a processing mode when the powder adhesive 17 is applied to the crimping postcard paper 24.

  The operator of the pressure-sensitive postcard making apparatus 1 determines the type of pressure-resistant postcard paper to be used when making the pressure-sensitive postcard using the pressure-bonded postcard making apparatus 1 and presses any of the buttons described above to apply the powder adhesive 17. Select the processing mode to apply.

  FIG. 6 is a diagram showing a data structure of a data table stored in the EEPROM of the control device corresponding to the above four processing modes. As shown in the figure, in the data table 30, four types of paper type columns are set vertically, and three types of control columns are set horizontally.

  In the setting of four types of paper types shown in the vertical direction, a postcard 1 field 31, a postcard 2 field 32, a postcard 3 field 33, and a postcard 4 field 34 are set. Each of these columns 31 to 34 corresponds to the processing mode selected by the processing mode selection buttons 25 to 28 shown in FIG.

  In addition, in the parentheses shown in the paper type column of the data table 30 shown in FIG. 6, the thickness (μm) of the paper of the paper type is shown for reference. That is, according to the figure, the rough textured thin paper pressure-sensitive postcard paper 21 has a thickness of 80 μm and the relatively thin high-quality paper pressure-sensitive postcard paper 22 has the same thickness of 80 μm. The high-quality paper pressure-sensitive postcard paper 23 has a thickness of 120 μm, and the relatively thick high-quality paper pressure-sensitive postcard paper 24 has a thickness of 150 μm.

  In this example, when the powder adhesive 17 is applied (transferred) to the pressure-bonded postcard paper by the adhesive application units 8-1 and 8-2, the data table 30 is stored in the transfer device 13. The transfer bias (v) shown in the transfer bias setting column 35 is applied.

  That is, a 900 v transfer bias is applied to the transfer device 13 in the case of the crimped postcard paper 21, a 1200 v transfer bias is applied to the transfer device 13 in the case of the crimped postcard paper 22, and a 1400 v transfer in the case of the crimped postcard paper 23. A bias is applied to the transfer unit 13, and in the case of the pressure-bonded postcard paper 24, a transfer bias of 1700 v is applied to the transfer unit 13.

  As described above, as the texture becomes finer or the thickness becomes thicker, a stronger transfer bias is applied to the transfer device 13. As a result, the finer the texture of the crimped postcard paper or the thicker the thickness, the more powder adhesive 17 is transferred to the crimped postcard paper.

  Further, in this example, when the applied powder adhesive 17 is assumed to be applied to the above-mentioned pressure-bonded postcard paper by the assumed attachment portions 9-1 and 9-2, the temperature of the assumed attachment portion is a data table. It is set to be the assumed wearing temperature (° C.) shown in the 30 assumed wearing temperature column 36.

  The setting of the assumed landing temperature is performed on the heat rollers of the assumed landing portions 9-1 and 9-2 while monitoring the outputs of the temperature sensors disposed in the assumed landing portions 9-1 and 9-2, respectively. This is executed by controlling the heat generation drive of the built-in heater.

  As a result, according to the data table 30, the entire sheet is heated at 168 ° C. in the case of the crimped postcard paper 21, and similarly heated at 168 ° C. in the case of the crimped postcard sheet 22, and 178 ° C. in the case of the crimped postcard sheet 23. In the case of the pressure-sensitive postcard paper 24, it is heated at 188 ° C.

As described above, the setting of the assumed wearing temperature changes in accordance with the difference in the paper quality of the pressure-bonded postcard paper, whereby the optimum assumed wearing according to the paper quality and the application amount of the powder adhesive is executed.
Further, in this example, when the assumed powder adhesive 17 is crimped to the above-mentioned crimping postcard paper by the crimping unit 5, the temperature of the crimping unit 5 is displayed in the crimping temperature column 37 of the data table 30. It is set to be the pressure bonding temperature (° C.) shown.

  The setting of the pressure bonding temperature is performed by controlling the heat generation drive of the heater built in the heat roller of the pressure bonding portion 5 while monitoring the output of the temperature sensor disposed in the pressure bonding portion 5.

  As a result, according to the data table 30, in the case of the pressure-bonded postcard paper 21, the entire paper is pressure-bonded while being heated at 178 ° C., and in the case of the pressure-bonded postcard paper 22, it is pressure-bonded while being heated at 178 ° C. In the case of 23, the pressure bonding is performed while being heated at 188 ° C., and in the case of the pressure-bonded postcard paper 24, the pressure bonding is performed while being heated at 198 ° C.

  In this way, the setting of the crimping temperature changes according to the difference in the paper quality of the crimped postcard paper, and as a result, the optimum crimping is performed according to the paper quality and the amount of powder adhesive applied. Regardless, regardless of the paper-type pressure-bonded postcard paper, the adhesive force can be maintained almost constant.

  In the above embodiment, the transfer bias, the assumed wearing temperature, and the crimping part temperature can be changed to appropriate processing modes according to the paper quality of the crimping postcard paper. However, the object of changing the processing mode is limited to this. is not.

  For example, the supply bias to the application roller, the transfer bias to the application roller, the bias voltage to the doctor blade that regulates the powder adhesive layer on the application roller, or the gripping pressure of the roller pair at the assumed attachment part or pressure bonding part is changed. You may make it do.

  Although not particularly shown, a measuring unit is provided for measuring the weight of one sheet when the postcard P is removed from the sheet feeding device 2, and based on the measured weight of the sheet, a transfer bias, A processing mode for setting the assumed wearing temperature and the pressure bonding temperature may be automatically selected.

  Also, when measuring the weight of pressure-bonded postcard paper, it is judged whether it exceeds the standard (2-6g) of government postcards or vice versa. It is also possible to provide a function that can be excluded.

  Further, not only the weight but also, for example, by measuring the size of the pressure-bonded postcard paper, it is determined whether the paper is for V-fold pressure-bonded postcards or Z-fold pressure-bonded postcards. The processing may be set in advance to V-folding or Z-folding.

  Further, by measuring the size of the pressure-bonded postcard paper, the control device may have a processing mode in which some data is reflected on the paper transport device, the adhesive application portion, the assumed attachment portion, the pressure-bonding portion, and the like.

  Further, not the weight and dimensions, but the thickness and electric resistance value of the crimped postcard may be measured, and the measurement result may be reflected in the processing mode. Of course, they may be combined and measured, and a processing mode reflecting the measurement data may be provided.
