Description

  The present invention relates to a pasting apparatus, and more specifically, a secret information printing surface coated with an adhesive of a sheet-like member on which secret information is printed is pressure-bonded or printed on a front surface and a back surface. The present invention relates to a pasting apparatus that crimps a folded sheet-like member into a bag shape.

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, 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 can be applied to a dedicated crimping machine, and a single printer or copying machine can be used to reach the dedicated crimping 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 a toner containing a heat-sensitive adhesive is used, and an image is created in a demand-responsive manner by an electrophotographic method. 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 mass, and that the composition of the heat-sensitive adhesive contains at least one selected from the group consisting of heat-adhesive resins, hot melts and waxes. (For example, refer to Patent Document 3.)
Conventionally, when manufacturing various types of paper bags and various types of film bags, a special large-sized apparatus is used to manufacture a large number of bags from a roll-shaped original fabric. (For example, see Patent Document 4)
The user generally purchases and uses various bags manufactured by such an apparatus for various purposes.

For example, in a medicine bag, each pharmacy as a user purchases a paper bag of various shapes, and hand-prints individual information such as name for each patient on the bag or prints it with a printer. The name and usage of the medicine to be packaged are handwritten or printed by a printer and handed to the patient.
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) JP 2000-203593 A (summary)

  By the way, although the technology of Patent Document 1 describes the configuration and composition of the microcapsule toner, the pulverized toner is only 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. In addition, 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.
Moreover, the technique of patent document 4 only shows the preparation method of a bag, It is not disclosed what kind of apparatus is used to create a bag.

  Aside from that, bags are generally purchased items, so when using, you must place an order for each type of bag (purpose of use) and size (shape) of the bag. .

  And it is necessary to store and manage inventory for each type and size. Further, in actual use, as described above, there is a problem in that it requires a complicated work for manually writing individual information or performing printing. In addition, there is a problem that it is expensive because it is a purchased item.

  In view of the above-described conventional situation, the object of the present invention is to establish a practical method for producing a powder adhesive, and then to determine the essence of a sheet-like member for a postcard or a medicine bag to which the powder adhesive is applied. In particular, the present invention is to provide a sticking apparatus that is small in size and high in performance so that a sheet-like member for a rectangular bag can be stably crimped and incorporated into a printer.

  The pasting apparatus of the present invention is a thermal pressure press that applies heat and pressure by a heating and pressing unit in a state where at least two or more sheet-like members coated with an adhesive made of a heat-melting powder are stationary. It is configured to be crimped by a method.

In this affixing device, for example, the temperature of the heat of the heating and pressing unit is 88 ° C. or higher, and the pressure is 0.1 MPa or higher.
Moreover, in this sticking apparatus, for example, the carrying-in direction and carrying-out direction of the sheet member with respect to the heating and pressing unit are configured to be horizontal.

  In this case, for example, it is configured to include a pushing member that pushes the sheet-like member into the heating and pressing unit immediately before the carry-in port of the heating and pressing unit. For example, when the sheet member is carried into the heating and pressing unit, the pushing member turns in the horizontal direction to form a carry-in guide path, and turns in the vertical direction when loading by the loading device is released. Then, it may be a rotating member that operates so as to push the rear end portion of the sheet member into the heating and pressing portion.

Also, the carry-out device for moving the inside and outside of the heating and pressurizing unit and carrying out the pressure-bonded sheet member out of the heating and pressurizing unit is provided at the carry-out port of the heating and pressurizing unit, for example. Is preferred.
In this case, the carry-out device may be a rotating roller.

Moreover, in this sticking apparatus, for example, the carrying-in direction and carrying-out direction of the sheet member with respect to the heating and pressing unit are configured to be vertical directions.
In this case, for example, the heating and pressurizing unit rotates in the horizontal direction during the operation of the thermal pressure press to prevent the sheet member from falling, and the heating and pressurizing unit You may comprise so that the rotation member which rotates in the perpendicular direction when the operation | movement of a heat pressure press is complete | finished and cancels | releases the fall prevention of the said sheet | seat member may be provided.

  Moreover, in this affixing device, for example, it is preferable that the heating and pressing unit has a release resin layer covered on the heating and pressing surface. In this case, the releasable resin layer may be a Teflon (registered trademark) resin layer or a silicon resin layer.

  In this affixing device, the pressurizing unit of the heating and pressurizing unit is configured to generate pressure by, for example, an oil method, an air method, or an eccentric cam method.

  According to the sticking apparatus of the present invention, even if it is a sheet member for a postcard that is crimped by overlapping two or more sheets, sufficient crimping is possible without excess or deficiency, and a sheet-like bag subjected to desired printing The material can be pressure-bonded so as to have sufficient strength at the joint.

<Size of crimp postcard paper>
2 (a) and 2 (b) are diagrams showing the size of paper used for printing as a pressure-sensitive postcard in the pressure-bonded postcard making apparatus 1, respectively.

  FIG. 4A shows an A4 size paper P-4. When the sheet is folded in two along a fold line 65 and cut along a cutting line 66, one surface is 14.85 cm long and 10.5 cm wide. These two bi-fold crimped postcards can be made.

  FIG. 5B shows a sheet P-3 in which one end P ′ in the longitudinal direction of the A3 size sheet is cut off by 10.5 cm in advance, and 3 along the two folding lines 67. When folded into two and cut along the cutting line 68, two tri-fold crimped postcards each having a length of 14.85 cm and a width of 10.5 cm can be produced.

  By the way, crimped postcards are usually handled as postcards, but according to the postal code, the size of one side of a private postcard is 14 to 15.4 cm on the long side and 9 to 10.7 cm on the short side. ing.

Therefore, the vertical and horizontal dimensions of one surface of the pressure-bonded postcard shown in FIGS. 2 (a) and 2 (b) are both within the allowable range of the postcard approved by the Postal Service.
These papers P-4 and P-3 shown in FIGS. 2 (a) and 2 (b) are presumed to have variable information printed on both sides, when powder adhesive is applied, and when powder adhesive is applied. When being folded and crimped, they are all conveyed in the direction of the cutting line 66 or 68 indicated by the arrow b.

<Operation of crimping postcard making device>
Subsequently, the operation of the pressure-bonded postcard creating apparatus 1 provided with the tandem type color image forming unit 9 (9m, 9c, 9y, 9k) having the above configuration will be described with reference to FIG. 1 described above again. First, power is turned on to the main unit shown in FIG. 1, and printing of variable information (printing) is performed when the paper quality, the number of sheets to be used, the print mode, and other specifications are input as a key input or a signal from a connected host device. ) And subsequent application of the powder adhesive.

  In the printing (printing) and the application of the powder adhesive in this example, the full color printing mode is initially set for each sheet, but the powder adhesive (B) is accommodated in the developing device 15. The image shape portion 9B is set to a non-printing state, and full-color printing is performed with four colors of magenta, cyan, yellow, and black by the four image forming portions 9 on the upstream side in the paper conveyance direction.

  First, the sheet feeding roller 28 takes out the uppermost sheet P of the sheet P placed and accommodated in the sheet cassette 3, and the lower sheet feeding roller pair 26, the double-sided transfer channel 25, the upper sheet feeding roller pair 24, The paper is fed to the standby roller pair 21 through the guide path 23.

The standby roller pair 21 temporarily stops rotating, the front end of the paper P is brought into contact with the holding portion to stop the progress of the paper, and waits for the conveyance timing.
The drive roller 7 rotates in the counterclockwise direction, and the driven roller 8 is driven to rotate in the same counterclockwise direction. As a result, the conveying belt 6 is circulated and moved in the counterclockwise direction with the upper circulating portion abutting against the four photosensitive drums 11 of the image forming portion 9.

  At the same time, various devices arranged around the photosensitive drum 11 are sequentially driven in accordance with the printing timing. The photosensitive drum 11 rotates in the clockwise direction, the initialization charger 13 applies a uniform high negative charge to the circumferential surface of the photosensitive drum 11, and the optical writing head 14 operates on the circumferential surface of the photosensitive drum 11. Then, exposure is performed according to the image signal to form a low potential portion. As a result, an electrostatic latent image composed of the high negative potential portion by the initialization and the low negative potential portion by the exposure is formed.

  The developing roller 16 transfers the toner of the developing device 15 to the low potential portion of the electrostatic latent image to form a toner image on the circumferential surface of the photosensitive drum 11 (reverse development). At the timing when the leading edge of the toner image on the circumferential surface of the photosensitive drum 11 of the most upstream image forming unit 9m is rotated and conveyed to the opposite part to the conveying belt 6, the printing start position of the paper P coincides with the opposite part. Thus, the standby roller pair 21 starts to rotate and feeds the paper P to the paper carry-in section.

  The transport belt 6 transports the fed paper P, whereby the paper P is transported to the first transfer section formed by the photosensitive drum 11 and the transfer sheet 17 of the image forming section 9m. The transfer sheet 17 applies a transfer current (or transfer voltage) output from a transfer bias power source (not shown) to the paper P via the conveyance belt 6. As a result, the M (magenta) toner image on the photosensitive drum 11 is transferred to the paper P.

  Subsequently, the C (cyan) toner image is transferred from the upstream transfer portion formed by the photosensitive drum 11 and the transfer sheet 17 of the image forming portion 9c, and further, the photosensitive drum 11 of the image forming portion 9y. A Y (yellow) toner image is transferred at the third transfer portion from the upstream formed by the transfer sheet 17. Then, the K (black) toner image is sequentially transferred at the most downstream transfer portion formed by the photosensitive drum 11 and the transfer sheet 17 of the image forming portion 9k, and the four color toner images are overlaid on the paper P. .

  The paper P onto which the four color toner images are transferred is separated from the transport belt 6 and carried into the fixing device 29. The fixing device 29 presses and holds the paper P by the heat roller 31 and the pressure roller 32, applies heat and pressure to the paper P while transporting it in the downstream direction, fixes the toner image on the paper surface, and discharges it to the rear.

  For example, in the case of single-sided printing during normal printing, the sheet P discharged from the fixing device 29 is rotated to the lower position indicated by the broken line in FIG. Then, it is guided upward along the paper discharge path 36, further reverses to the front of the apparatus at the end, and sandwiched by the paper discharge roller pair 37 to further carry over, with the image forming surface facing downward from the upper paper discharge port 5. The paper is discharged onto the upper paper discharge tray 4.

  When the paper P is double-sided printing during normal printing, or when printing on a pressure-sensitive postcard paper (because it is always double-sided printing), the switching flap 34 is at the position of the broken line in FIG. Then, the paper is taken over and guided upward along the paper discharge path 36, and stops when the rear end (right end portion in the figure) of the paper P reaches the pair of transport rollers 35.

  This stop timing is determined by a predetermined number of drive pulses such as a stepping motor that drives the transport roller pair 35 by the control device of the electrical unit 64 based on detection of a paper size by a paper feed sensor (not shown) when paper P is fed. Determined by setting to a value. Of course, a sensor may be provided in the vicinity of the conveying roller pair 35 to detect the trailing edge of the sheet.

  Next, the conveyance roller pair 35 starts to rotate in the opposite direction to feed the paper P back, and the rear end of the paper P is nipped by the first reverse conveyance roller pair 42 a of the feed-back conveyance path 41. Then, the feed-back conveyance path 41 is sequentially fed back to the reverse conveyance roller pairs 42 b, 42 c, 42 d, 42 e and joins the double-sided transfer merge path 25.

  Then, the sheet P is conveyed again by the conveying roller pair 24, passes through the paper feed guide path 23, is reversed, the image forming surface faces downward, and the rear end of the sheet P on which the image non-formed surface faces upward is the leading edge. Then, it comes into contact with the standby roller pair 21 and stops temporarily.

Thereafter, similarly to the case of printing on the first side (front side), toner images of four colors are sequentially transferred onto the back side of the paper, and the toner images are fixed by the fixing device 29.
Thereafter, in the case of double-sided printing of normal printing, the paper P is discharged from the upper paper discharge port 5 to the outside of the apparatus. However, in the case of the pressure-bonded postcard paper P-4 or P-3, it is sent back to the feed-back transport path 41 again.

  At the same time, the setting of the full color printing mode is canceled and the powder adhesive application mode is set. As a result, the four image forming units 9 (9m, 9c, 9y, 9k) on the upstream side in the sheet conveying direction are set to the non-printing state, and the image forming unit 9B that stores the powder adhesive (B) in the developing unit 15 is used. Is set to the print state.

  Then, in the same manner as in the case of single-sided printing or double-sided printing described above, the powder adhesive application process by only the image shape part 9B is applied to the surface of the pressure-sensitive postcard paper P-4 or P-3 on which variable information has been printed. Done.

Here, the mode of variable information printing and powder adhesive application of the pressure-bonded postcard paper P-4 or P-3 will be described.
FIG. 3 (a) is a diagram showing a mode at the end of variable information printing on the pressure-bonded postcard paper P-4, and FIG. 3 (b) is a diagram showing a mode at the end of applying the powder adhesive, FIG. () Is a diagram showing a state when the paper is folded. Arrows b shown in FIGS. 9A, 9B, and 9C are the arrows b shown in FIG. 2, and indicate the conveyance direction of the crimped postcard paper P-4.

  Concealment variable information “Invoice, December, 20,000 yen, until January 31” is printed by the image forming unit 9 on the front side of the crimped postcard paper P-4 shown in FIG. Has been. In addition, public variable information such as a sender name and a destination name is printed on the opposite side which cannot be seen in the figure.

  As shown in FIG. 2B, a powder adhesive 69 is applied to the print surface of the above-described secret variable information by the image forming unit 9B. Then, the folded portion 38 is folded into a V shape so that the application surfaces of the powder adhesive 69 face each other, as shown in FIG.

  FIG. 4A is a plan view showing a state at the end of variable information printing on the pressure-bonded postcard paper P-3. FIGS. 4B and 4C are views at the end of the application of the powder adhesive. FIG. 4D is a diagram showing a perspective view of the folded state of the paper.

In addition, the arrow b shown to the same figure (a), (b), (c), (d) is also the arrow b shown in FIG. 2, and has shown the conveyance direction of the crimping postcard paper P-3.
In FIG. 5A, illustration of variable information printed on the entire front and back surfaces of the pressure-bonded postcard paper P-3 is omitted. When the double-sided printing of the variable information is completed, a powder adhesive 69 is first applied to the secret variable information printing surfaces PA and PB on the first side of the variable information as shown in FIG.

  Subsequently, a powder adhesive 69 is applied to the secret variable information printing surfaces PE and PF on the second surface side as shown in FIG. Then, the folded portion 38 is folded into a Z shape so that the application surfaces of the powder adhesive 69 face each other, as shown in FIG.

  In FIG. 1, such folding is performed when the sheet P on which variable information printing and powder adhesive application have been completed is presumed to be powder adhesive by the fixing device 29, and the downstream side by the fixing discharge roller pair 33. Since the switching flap 34 is rotated to the upper position indicated by the solid line in the drawing, it is carried into the folding portion 38 through the folding loading port 39 and executed.

<Configuration and operation of folding unit 38>
FIGS. 5 (a) to 5 (e) show that the A4 size paper P-4 shown in FIG. 3 (a) has been printed with variable information and applied with a powder adhesive, and the two are still connected. It is a figure which shows the bending method of the V-fold crimping | compression-bonding postcard folded in half in the state (before the stage cut | judged with a splitter).

  First, as shown by an arrow e in FIG. 5A, the paper P-4 is carried into the folding entrance 39 of the folding section 38. Therefore, the primary conveyance roller 43 and the primary secondary conveyance roller 44 are paired to grip and rotate the paper P-4, and as shown in FIG. 5B, the paper P-4 is moved to the primary drawing path 47. Operates to send out.

  As shown in FIG. 5 (b), the primary folding device 46 uses a folding line 65 (see FIG. 2 (a)) of the paper P-4 stretched between the folding inlet 39 and the primary drawing path 47 as shown in FIG. As shown in (c), the folding plate 45 is protruded and folded into the opposing portion between the primary secondary conveyance roller 44 and the secondary tertiary conveyance roller 48.

  Subsequently, as shown in FIG. 5 (d), the primary secondary conveyance roller 44 and the secondary tertiary conveyance roller 48 are paired to grip and rotate the folded end of the sheet P-4, and the sheet P -4 is sent out in the direction of the secondary pull-in path 53.

  The secondary folding device 52 projects the folding / guide plate 51 at a timing when the folded front end of the sheet P-4 slightly passes the facing portion between the secondary tertiary transport roller 48 and the tertiary transport roller 49. The leading edge of the sheet P-4 that is folded and protruded is guided in the direction of the opposing portion between the secondary and tertiary conveyance rollers 48 and the tertiary conveyance roller 49.

  A pair of secondary and tertiary conveyance rollers 48 and a tertiary conveyance roller 49 sandwich the leading end of the sheet P-4 that is folded and protruded, and rotate. As a result, as shown in FIG. 5 (e), the sheet P-4 is sent out to the pasting device 55 while the succeeding portion is folded in two from the folding leading end portion.

  6 (a) to 6 (e), the paper P-3 corresponding to A3 size shown in FIG. 2 (b) has completed the printing of variable information and the application of the powder adhesive, and the two are connected. It is a figure which shows the bending method of the Z fold crimping | crimping postcard which is made into three folds in the state as it is (before cutting with a splitter).

First, FIG. 6 (a) shows a state where the sheet has been folded up to two as in the case of FIGS. 5 (a) to 5 (d).
Thereafter, the primary conveyance roller 43 and the primary secondary conveyance roller 44 are paired to feed the rear portion of the sheet P-3, and the primary secondary conveyance roller 44 and the secondary and tertiary conveyance roller 48 are paired to form the sheet P. -3 and grips and rotates the paper sheet P-3 in the direction of the secondary pull-in path 53 as shown in FIG.

  The second P-3 roller and the third transfer roller 49 have a mating portion P-3-12 of the first sheet P-3-1 and the second sheet P-3-2 that are folded into the two of the sheet P-3. 6 (c), the secondary folding device 52 projects the folding / guide plate 51, and the third sheet P-3-3 at the end of the sheet P-3 is reached. Fold it in.

  As shown in FIG. 6 (d), the second and third transport rollers 48 and 49 are paired, and the third sheet P-3-3 at the end of the sheet P-3 is folded into a triple. It rotates by pinching the protruding three-fold part.

As a result, as shown in FIG. 6 (e), the paper P- 3 is sent out to the pasting device 55 while being folded in three by the secondary and tertiary transport rollers 48 and the tertiary transport roller 49.
Returning to FIG. 1, the two-folded paper P-4 or the three-folded paper P-3 fed to the pasting device 55 as described above is immediately carried into the pasting device 55, and heat and pressure are applied to the powder. The application surface of the adhesive 69 is pressure-bonded.

Here, as the affixing device 55, a device composed of only a simple heat roller used for fixing an electrophotographic toner image, such as the fixing device 29 of FIG.
<When the pasting device 55 is only a pair of heat rollers>
FIG. 7 (a) shows a pressure-bonding mode in the case of the double-folded paper P-4 when the sticking device 55 is composed of only a pair of heat rollers, and FIG. 7 (b) shows three cases in the same case. It is a figure which shows the aspect of the crimping | compression-bonding in the case of the folded paper P-3.

  In any of the cases shown in FIGS. 4A and 4B, the adhesive 69 is sandwiched between the crimping postcard paper P-4 or P-3. In order to heat and melt the adhesive 69, it is sandwiched and pressed by a pair of heat rollers 71 (71a, 71b) from the outside, and heat is applied as indicated by arrows c and d through the pressure-bonded postcard paper P-4 or P-3. Need to transmit osmotic. However, in such cases, the following problems can be considered.

  First, as (a), in the adhesive-type Z-fold postcard adhesion, a three-layer structure in which an adhesive is sandwiched between cardboards is employed. In order to attach the pressure-bonding postcard, it is necessary to heat and melt the adhesive. However, as is clear from the above figure, since heat needs to be transmitted through the paper P, the thermal efficiency is very poor.

  In the case of a heat roller, the area where the crimping postcard can be heated is the nip width, which is the contact area between the rollers. In order to transfer a large amount of heat to the postcard, one is to increase the nip width, two is to increase the roller temperature, and three is to slow down the conveying line speed of the paper P. There is a way.

  However, it is difficult to increase the nip width structurally, and it is difficult to increase the temperature to 200 degrees or more even at a temperature, and there is a risk of fire or the like. Therefore, the only remaining method is a method of extremely slowing the conveyance linear velocity.

  Next, as (b), curling is likely to occur. In particular, in the case of Z-folding shown in FIG. 7B, since the paper P having three layers is sandwiched between the heat roller pair 71, the stress applied to the paper becomes a complex pattern and curling is likely to occur.

  Further, as (C), misalignment of paper (postcard) and adhesion floating (partially not adhered) are likely to occur. That is, in the case of Z-folding shown in FIG. 7B, when the Z-folded paper P-3 passes through the heat roller pair 71, the conveying force that the paper P-3 receives from the heat roller pair 71 is from the heat roller 71a. Is applied to the upper layer of the Z-fold, and the transfer force f from the heat roller 71b is applied to the lower layer of the Z-fold. That is, the Z-fold intermediate layer does not receive the conveying force directly.

  By the way, since the adhesive 69 is not melted before passing through the heat roller pair 71, the upper layer, the intermediate layer, and the lower layer of the sheet P-3 are in a mutually free state. Accordingly, a deviation is likely to occur between the upper layer and the intermediate layer and between the lower layer and the intermediate layer.

When pasted in this shifted state, the sheet is shifted, or a part of the sheet is shifted and the adhesive floats to adhere to the lifted state.
As other pressure bonding methods, a preheating method in which a heating device is passed before being sandwiched between a pair of heat rollers, or a belt method in which pressure is applied while being conveyed by a heat belt from above and below are conceivable. However, the following problems can be considered in these cases.

  First, as (d), in order to paste the paper P while moving, the degree of conveyance line x pasting time = the total length of the heating area (size of the pasting device) is required. Therefore, there is a drawback that the apparatus becomes large.

  Next, as (e), problems such as curling, paper misalignment, and adhesion floating easily occur. This is because, as in the case of only the heat roller pair described above, basically a structure is adopted in which three layers of paper are sandwiched between two rollers.

  As described above, it is predicted that various problems will occur in the mere heat roller pair, the preheating method, and the heat belt method, but the application device 55 shown in FIG. 1 solves the above problem. It is a thing.

<Affixing device 55 in Embodiment 2>
FIGS. 8A and 8B are diagrams illustrating the configuration of the pasting device 55 and the operation state thereof in the second embodiment.

  9 (a) and 9 (b) are diagrams for explaining the operation state of the pasting device 55 following FIG. 8 (b). 8A and 8B and FIGS. 9A and 9B also show the secondary and tertiary conveyance rollers 48 and the tertiary conveyance roller 49 of the folding portion 38.

<Configuration of pasting device 55>
As shown in FIG. 8A, the sticking device 55 includes the press device 54, the heat source 56, the conveying roller pair 57, and the discharge roller pair 58 described above. The press device 54 includes a movable upper press portion 54a and a fixed lower press portion 54b. The press device 54 is arranged in the press chamber 72 so that the flat portions of the metal material face each other, and the upper press portion 54a descends to lower the lower press portion. It is comprised so that 54b may be pressurized.

  The heat sources 56 are incorporated in the vicinity of the metal material plane portions of the upper press portion 54a and the lower press portion 54b, respectively. These heat sources 56 are supplied with heat generation voltage from a power source (not shown). Thereby, the metal material plane portions of the upper press portion 54 a and the lower press portion 54 b constitute a heating and pressing portion in the press chamber 72.

  In addition, a temperature sensor (not shown) is disposed in the vicinity of the plane portion in which the heat source 56 is incorporated. A temperature sensor detects the temperature of a plane part, and notifies the detected temperature to the control apparatus of the electrical equipment part 64 via an electric circuit not shown.

The control unit performs on / off control of the supply voltage for heat generation in order to maintain the temperature of the flat part at a predetermined temperature while monitoring the temperature notified from the temperature sensor.
Further, a release resin 73 is covered on each of the metal material plane portions of the upper press portion 54a and the lower press portion 54b of the press device 54. The releasable resin 73 is provided in order to prevent characters such as an address printed on the sheet-like member from being offset to the flat portion. The releasable resin 73 is formed of a Teflon (registered trademark) resin layer or a silicon resin layer.

  Further, the transport roller pair 57 is disposed between the carry-in port of the press chamber 72 and the secondary and tertiary transport rollers 48 and the tertiary transport roller 49 of the folding unit 38. And the pushing member 74 is horizontally arrange | positioned so that said conveyance roller pair 57 may be pinched | interposed from both sides. The pushing member 74 is rotatable between a horizontal solid line position and a vertical broken line position shown in FIG.

  In addition, a discharge roller 75 is disposed in the vicinity of the carry-out port inside the press chamber 72 so as to be able to enter and exit the solid line position and the broken line position shown in the drawing. A guide plate 76 is arranged on the downstream side (left side in the figure) from the outlet of the press chamber 72, and the discharge roller pair 58 shown in FIG. 1 is arranged on the downstream side.

As shown in FIG. 8 (a), in the pasting device 55, the paper carry-in direction and the carry-out direction with respect to the heating and pressing unit (press chamber 72) are horizontal.
<Operation of the pasting device 55>
The paper P (P-4 or P-3) shown in FIGS. 2A and 2B is printed with variable information by the image forming unit 9 shown in FIG. As shown in FIG. 5 or FIG. 6, the powder adhesive 69 is applied, V-folded or Z-folded, and sandwiched between the secondary and tertiary transport rollers 48 and the tertiary transport roller 49, as shown in FIG. Are fed in the direction of arrow g shown in FIG.

  The conveyance roller pair 57 that has taken over the conveyance of the sheet P in the pasting device 55 sends the front part of the sheet P to the heating and pressing unit (press chamber 72). The pushing member 74 is rotated to a horizontal position and guides the conveyance of the paper P.

  The conveyance of the paper P by the conveyance roller pair 57 stops immediately after the rear end portion of the paper P leaves the holding portion of the conveyance roller pair 57. At this time, on the downstream side of the conveyance roller pair 57, at least a length portion of the rear end portion of the paper P corresponding to the radius of the conveyance roller is not carried into the heating and pressurizing unit (press chamber 72).

  Here, as shown in FIG. 8B, the pushing member 74 is rotated to the vertical position. As a result, the unloading portion of the rear end portion of the paper P that is on the pressing member 74 on the downstream side of the conveying roller pair 57 is pressed by the pressing member 74 that rotates to the vertical position, and is heated and pressurized. It completely enters the section (press chamber 72).

At substantially the same time, the paper discharge roller 75 is retracted from the inside of the press chamber 72 to the retracted position indicated by the solid line in FIG.
Subsequently, as shown in FIG. 9A, the upper press portion 54a of the press device 54 descends and presses the paper P against the lower press portion 54b. Thereby, the press device 54 pressurizes the paper P and heats the paper P by the heat source 56. The appropriate pressing amount and temperature at this time will be described later in detail.

  Note that the pressure generated by the lowering of the upper press portion 54a and the pressing against the lower press portion 54b can be performed by any of an oil method, an air method, and an eccentric cam method, although not particularly illustrated.

  When pressurization and heating to the paper P are completed as described above, as shown in FIG. 9 (b), the upper press portion 54a is raised, and the pushing member 74 is rotated to the horizontal position and arranged at the guide position. Then, the paper discharge roller 75 is disposed from the retracted position indicated by the broken line to the paper discharge position indicated by the solid line, and is rotated to discharge the paper P that has been pasted.

The paper discharge is taken over by the discharge roller pair 58, and the paper P is conveyed downstream from the pasting device 55.
The next paper P is fed to the affixing device 55 by the secondary and tertiary transport rollers 48 and the tertiary transport roller 49 of the folding unit 38 so as to be substantially interlocked with this. The sheet P is carried into the press chamber 72 by the conveying roller pair 57.

<Experiment with the pasting device 55 in Embodiment 2>
With the above-described configuration, the pasting device 55 operating as described above performed pasting processing based on various conditions and evaluated the results. The conditions for the pasting process are as follows.
(A) Printing variable information characters: A Casio Computer Page Printer N6000 was used as the printer, and genuine toner was used.
(B) Adhesive: a powder having an average particle size of about 9 μm, which is made of a binder resin made by a manufacturing method similar to that of a toner and others, and has a ½ method melting temperature higher by 5 ° C. than the toner. The agent was used. (Note that CFT-500D manufactured by Shimadzu Seiki Co., Ltd. was used as an adhesive and toner thermal property measuring instrument.)
(C) Application of adhesive: After the entire surface was applied to the affixed surface by an electrophotographic developing method, it was fixed through a normal fixing device.
(D) Paper: Plain paper having a basis weight of 104.7 g was used.
(E) Temperature: The temperature was set in 8 steps from 70 ° C. to 140 ° C. at 10 ° C. intervals.
(F) Pressure: The pressure was set to five levels of 0.05 MPa, 0.1 MPa, 0.25 MPa, 1.0 MPa, and 1.5 MPa.
(G) Press duration: 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds.
(H) Evaluation items: Adhesive strength, curling property, paper misalignment, and adhesion floating were evaluated.

  FIGS. 10A, 10B, and 10C are charts showing evaluation results corresponding to the setting conditions. In either case, the temperature conditions are shown horizontally in 8 steps from 70 ° C. to 140 ° C. at 10 ° C. intervals, and the pressing duration conditions are shown in 5 steps in 1 second intervals from 1 second to 5 seconds.

  The same figure (a) shows the result when the pressure condition is 0.25 MPa, 1.0 MPa or 1.5 MPa, and the same figure (b) shows the result when the pressure condition is 0.1 MPa. The results are shown, and FIG. 4 (c) shows the results when the pressure condition is 0.05 MPa.

  In the results and the evaluation, in all of the figures (a), (b), and (c), the evaluation shown in the split portion corresponding to the eight temperature conditions and the five pressing duration conditions "-" Indicates that there was no adhesion. In addition, “Δ” indicates that some of the adhesive force is weak. “O / O” indicates that the folded paper has good adhesion and no defects such as curling and paper misalignment.

  When the pressure condition in FIG. 10 (a) is 0.25 MPa, 1.0 MPa, or 1.5 MPa, the evaluation is clearly divided into “−” and “◯ / ○” depending on the set temperature, and stable condition setting is possible. It is shown that it can be pasted.

  In particular, when the pressing duration is 5 seconds, the set temperature is 80 ° C. at the start of adhesion, and when the pressing duration is 4 seconds, the setting temperature is 90 ° C. at the start of adhesion, and both adhere at a low temperature below 100 ° C. It has begun.

This is a value about 10 ° C. lower than other methods such as a preheating method and a belt method. The results of other types of adhesion tests and evaluations are not shown.
In addition, when the pressure condition shown in FIG. 10 (b) is 0.1 MPa, there is a set temperature that is evaluated as “Δ” between “−” and “O / O”, and a somewhat unstable environment appears. However, it is found that if the set temperature is sufficiently high within the range of 70 ° C. to 140 ° C., for example, even when the pressing duration is 1 second, a favorable “◯ / ○” evaluation can be obtained. .

  In addition, when the pressure condition shown in FIG. 10 (c) is 0.05 MPa, there is a temperature range where the evaluation is “Δ” at both the high temperature and the low temperature across the set temperature where the evaluation is “◯ / ○”. This indicates that the proper environment in which extremely strong adhesion occurs is unstable.

  Summarizing the above experimental results, it can be seen that the low set pressure at which a good evaluation can be obtained as long as the combination of temperature and pressing duration is suitable is at least 0.1 MPa. Moreover, it turns out that the low temperature at which a good evaluation is always obtained as long as the combination of the set pressure and the pressing duration is suitable is at least 80 ° C.

  As can be seen from the above evaluation, there are “−” and “Δ” for the adhesive force, but the evaluation of the occurrence of defects such as curling and paper misalignment is only “O” indicating no, and “ “×” did not exist.

  This is because, in the case of the hot press method, since the paper is pasted by heating and pressurization in a static state where the paper is not moving, it is considered that the paper is bonded evenly and efficiently. . This is considered to be the cause of the above-mentioned excellent point.

  As described above, according to the present embodiment, it is possible to attach a sheet-like member without curling, paper misalignment, and adhesion floating. As a result, it is possible to easily crimp only the necessary portions of the sheet-like member for a crimping postcard coated with a powder adhesive or the sheet-like member for an essentially rectangular bag, such as a medicine bag, and to be incorporated into a printer. It is possible to provide a compact and high-performance pasting device.

  Further, the sheet-like member can be attached at a lower temperature than other apparatuses. Moreover, even if it is a case where sticking time is taken long, in order to stick a sheet-like member in a stationary state, a sticking apparatus can be comprised as small as possible.

(Embodiment 3)
FIG. 11 is a diagram illustrating a configuration of a pasting device as the third embodiment. In the figure, the same components as those shown in FIG. 8A are denoted by the same reference numerals as those in FIG. 8A.

  As shown in FIG. 11, the pasting device 77 of this example has a shape in which the pasting device 55 shown in FIGS. 8 (a) and 8 (b) is a vertical type, and the paper P (not shown in FIG. 11) is placed on the top. This is a method of conveying from the bottom to the bottom, that is, in the vertical direction.

  In this example, the paper P carried into the pasting device 77 falls due to gravity after leaving the holding roller 57. Therefore, the rotating member 78 disposed between the carry-in port of the press chamber 72 and the secondary and tertiary conveyance rollers 48 and the tertiary conveyance roller 49 of the folding unit 38 does not have a sheet pushing function, and functions as a sheet guide. And only the function of sealing the entrance of the press chamber 72 when the hot press is performed.

  Further, another rotating member 79 that also serves as a guide plate is disposed at the paper discharge port of the press chamber 72 of this example. This rotating member 79 rotates in the horizontal direction indicated by the broken line during the operation of the heat and pressure press of the sticking device 77 to prevent the paper P from falling, and the heat and pressure portion of the hot press press is the heat pressure press. When the operation is finished, the sheet P is rotated in the vertical direction indicated by the solid line, and the fall prevention of the paper P is released.

  The configuration and operation of the parts other than those described above are the same as those in the second embodiment. With such a configuration and operation, in this example, the paper P falls by its own weight without the paper discharge roller 75 shown in FIG. To be discharged. Therefore, in this example, the paper discharge roller 75 shown in FIG. 9B can be eliminated.

(Embodiment 4)
FIG. 12 is a diagram illustrating a configuration of a pasting apparatus according to the fourth embodiment. In the figure, the same components as those shown in FIG. 8A are denoted by the same reference numerals as those in FIG. 8A.

  As shown in the figure, in the pasting device 80 of this example, a releasable liquid tank 81 is disposed above the vicinity of the discharge port of the press chamber 72. The releasable liquid tank 81 contains a releasable liquid 82. A first application roller 83 is in close contact with the lower opening of the releasable liquid tank 81 in a rotatable manner.

  With the rotation of the first application roller 83, the releasable liquid 82 is applied to the surface. When the second application roller 84 that can move between the first application roller 83 and the discharge port of the press chamber 72 moves toward the first application roller 83 and presses against the first application roller 83, The releasable liquid 82 in the releasable liquid tank 81 is applied to the second application roller 84 via the first application roller 83.

When the pressurization process of heating and pressurization in the press chamber 72 is completed, the upper press portion 54 a is raised, and the press chamber 72 is opened, the second application roller 84 moves to the discharge port of the press chamber 72.
The second application roller 84 that has moved to the discharge port of the press chamber 72 contacts the inside of the press chamber 72 with the surface of the release resin 73 on the flat surface of the metal material, as indicated by a dashed line 85 in the drawing. However, it is configured to be able to rotate from the discharge port end to the carry-in end.

  Thereby, the releasable liquid 82 applied to the second application roller 84 is transferred to the surface of the layer of the releasable resin 73 and applied. Thereby, in this example, it becomes possible to further improve the offset prevention function of the pressing surface which consists of a metal material plane part in which the layer of releasable resin 73 is formed.

  As described above, since the pasting apparatus of the present invention is a press type, curling, misalignment, and adhesion floating do not occur in the sheet-like member to be pasted, so a beautiful adhesive with no wrinkles in the finished appearance is created. can do.

  That is, according to the present invention, it is possible to produce a V-folded or Z-folded crimped postcard using plain paper, and for an essentially rectangular bag such as a medicine bag using an appropriate sheet material. Only necessary portions of the sheet-like member can be easily attached without problems such as curling, displacement, and adhesion floating.
