JP4840054B2 - Powder adhesive intermediate transfer body - Google Patents

Description

  The present invention relates to a powder adhesive intermediate transfer body that prints address and confidential information on a pressure-sensitive postcard sheet, and then efficiently transfers and applies a powder adhesive for bonding onto the confidential information printing surface.

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 unavoidable, and it is inevitable that handling is complicated, and it is better to make several crimping postcards personally, but it is cheap, quick, and responsive to demand in a certain number of sheets. 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. At the time of 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 into a replacement printing cartridge for an office printer or a copying machine, and the pressure bonding substance is applied to a government 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 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.

  In the technique of Patent Document 3, the softening temperature of the heat-sensitive adhesive is simply set higher than the softening temperature of the binder resin of the toner for the electrophotographic system. There is no explanation of prescription.

  By the way, as a method of creating a pressure-sensitive postcard that is responsive to demand, a powder adhesive that can be used by being housed in a toner cartridge of a small electrophotographic printer that can be used personally is specifically realized. It is considered that the powder adhesive may be applied to the paper surface on which variable information is printed (or printed, the same applies hereinafter) by the same printer by developing, transferring and fixing.

  However, if the adhesive is applied to the paper after printing using an electrophotographic printer, the powder adhesive must be applied as an adhesive unless it is of the same form as a normal toner ( Development, transfer, and fixing) are considered impossible.

  However, although the powder adhesive for toner-like pressure-adhesive postcards is suggested to the extent of conceiving in the above-mentioned patent documents, which are the conventional proposed technologies, the specific material formulation is also specific as described above. Neither usage is disclosed.

Also, such a toner adhesive powder adhesive for postcards has not been distributed to the market to date. The pressure-sensitive adhesive for postcards in circulation is only liquid or adhesive sheet.
In addition, after printing the address and confidential information on the crimping postcard paper with an electrophotographic printer, a post-processing method such as the folding process, adhesive application process, confidential information printing surface pressure bonding process, etc. There is still no disclosure or suggestion of how to properly deal with possible paper jams.

  An object of the present invention is to produce a practical powder adhesive made of a specific material prescription in view of the above-described conventional situation, and the address and secret information are printed in advance using the powder adhesive. An object of the present invention is to provide a powder adhesive intermediate transfer body for efficiently transferring and applying a powder adhesive to a secret information printing surface of a pressure-sensitive postcard sheet, that is, a bonding surface of the pressure-sensitive postcard sheet.

  The powder adhesive intermediate transfer body of the present invention is a powder adhesive intermediate transfer body in which a powder adhesive having an electrostatic potential is applied to a bonding surface of a pressure-sensitive postcard sheet by transfer, and the application portion and Application part, insulating layer that insulates application part and non-application part, application part conductive layer that conducts to application part, non-application part conductive layer that conducts to non-application part, and application part conductivity And a voltage application unit that applies different voltages to the application unit and the non-application unit via the conductive layer and the non-application unit conductive layer.

The voltage application unit is configured to switch a voltage applied to the application unit via the application unit conductive layer between an application voltage and a non-application voltage, for example.
The powder adhesive intermediate transfer member may be, for example, a drum in which the application part, the non-application part, and the insulating layer are formed on the surface carrying the powder adhesive. An endless belt in which the coated portion, the non-coated portion, and the insulating layer are formed on the surface carrying the powder adhesive may be used.

  According to the present invention, since the powder adhesive is applied to the desired affixing surface of the pressure-sensitive postcard sheet using the intermediate transfer body having the application part and the non-application part, the same powder as the toner is transferred as the adhesive. However, since it is not necessary to use an electrophotographic exposure head or a photosensitive drum, the cost of the transfer portion can be reduced.

  In addition, since the bias voltage to the application part of the intermediate transfer member can be switched, it is possible to select whether or not the adhesive is applied to the sheet according to the shape of the pasting surface. It is convenient because it can easily cope with adhesive application shapes such as a sheet, a Z-fold crimping postcard sheet, and a temporary folding crimping postcard sheet.

Embodiments of the present invention will be described below with reference to the drawings.

Only one mail is shown. 4D and 4E show that the single surface on which the powder adhesive 17 is applied in the adhesive application unit 5 is the surface F and the surface A. FIG.

Hereinafter, the crimping postcard manufacturing process of this example will be described with reference to FIGS. First, the sheet 18 or the sheet 16 is fed from the sheet feeding unit 2 in FIG.
The sheet feeding unit 2 stores sheets 16 or 18 on which an address, secret information, sender name, and the like are printed in advance, and these sheets 16 or 18 are sequentially fed.

  In this paper feeding, only one sheet 18 or 16 conveyed in the direction of the arrow is shown in FIG. 1 for the purpose of avoiding the complexity of the illustration, but in actuality, FIG. ), (b) As shown in FIGS. 2 (a) and 2 (b), two sheets 18 or 16 of the postcards that are still connected by the cutting line 13 or 15 are conveyed in the direction of arrow b in FIGS. 2 (a) and 2 (b). .

  During the conveyance to the temporary folding unit 4, the sheet sensor 3 detects the timing at which the sheet 16 or 18 is carried into the main body of the crimping postcard making apparatus 1, and this detection signal is notified to a control unit (not shown). .

  In the case of the sheet 16, in the temporary folding part 4, as shown in FIG. 3B and FIG. The sheet 16 folded in this way is conveyed to the adhesive application unit 5.

  In the case of the sheet 18, as shown in FIGS. 4B and 4C, a part of the sheet (surface C and surface F on the front and back sides) is folded as indicated by an arrow j. The sheet 18 in which a part of the sheet is folded is conveyed to the adhesive application unit 5.

  The adhesive application unit 5 has a powder adhesive container 19, and a lower end opening of the powder adhesive container 19 has an adhesive supply roller 21 on the inside and an adhesive supply roller 21 on the outside. An intermediate transfer drum 22 that is in pressure contact is provided.

In addition, a transfer roller 24 that is pressed against the intermediate transfer drum 22 via the sheet conveyance path 23 is disposed, and a cleaner 25 that cleans the peripheral surface of the intermediate transfer drum 22 is disposed.
The sheet 18 or 16 carried into the adhesive application unit 5 along the sheet conveyance path 23 is applied with the powder adhesive 17 on the upper surface while being nipped and conveyed by the intermediate transfer drum 22 and the transfer roller 24.

  In the case of the sheet 18, the upper surface to which the powder adhesive 17 is applied is a surface composed of a surface F of FIG. 4C and an unfolded surface A that is exposed side by side with the folded surface F. As shown in FIG. 4 (d), the powder adhesive 17 is applied at once to the predetermined surfaces (surface F and surface A) on the back surface and the front and back surfaces.

  In the case of the sheet 16, the upper surface to which the powder adhesive 17 is applied is the second surface c shown in FIG. 3 (c). As shown in d), a powder adhesive 17 is applied.

  The sheet 18 or 16 coated with the powder adhesive 17 is conveyed to the temporary / main fixing unit 6. A lower endless heat belt 26 and pressure rollers 27 and 28 are disposed in the sheet carry-in portion of the temporary and main fixing portion 6 so as to sandwich the lower endless heat belt 26 from above and below and form an assumed attachment portion.

  The pressure roller 28 located on the lower surface (outside) of the lower endless heat belt 26 is always in contact with the lower surface of the lower endless heat belt 26, and the pressure roller 27 disposed opposite the pressure roller 28 is assumed to be worn. When it moves downward, the lower endless heat belt 26 is pressed toward the pressure roller 27.

  As a result, the sheet 18 or 16 is nipped and conveyed by the lower endless heat belt 26 and the pressure roller 28, and heat and pressure are applied, so that the powder adhesive 17 is put on the paper surface. An oil application roller 31 is in contact with the outer end portion of the lower endless heat belt 26 on the downstream side, which will be described later.

  The sheet 18 or 16 on which the powder adhesive 17 is presupposed on the paper surface is then conveyed to the main folding unit 7. First, the folded surface of the sheet 18 or 16 carried into the main folding section 7 is once expanded.

  FIG. 3 (e) shows the first surface (surface a, surface b) of the sheet 16 unfolded as shown by the arrow k. Although not visible in FIG. 3 (e), The above-mentioned powder adhesive 17 is presumed on the surface c of the second surface (back surface).

  FIG. 4 (e) shows the first surface (surface A, surface B, surface C) of the sheet 18 spread as indicated by the arrow m, and the above-mentioned powder adhesive is applied to the surface A. 17 is assumed. Further, in FIG. 4 (e), although it is not visible in the shade, the above-described powder adhesive 17 is presupposed on the surface F of the second surface (back surface).

Thereafter, in the case of the sheet 16 in the main folding portion 7, the surface c is folded toward the surface d as shown by the arrow n as shown in FIG. As a result, the sheet 16 is V-folded.
In the case of the sheet 18, as shown in FIG. 4 (f), the surface F is folded to the surface E side, and the surface B that is continuously folded and doubled with the surface F is folded to the surface A side. It is. As a result, the sheet 18 is Z-folded.

  The sheet 16 or 18 that is V-folded or Z-folded is conveyed again to the temporary / main fixing unit 6. However, this time, the sheet 16 or 18 is carried into the main fixing unit in which the lower endless heat belt 26 and the upper endless heat belt 29 are arranged to face each other.

  Three pressure rollers including the pressure roller 27 described above are arranged inside the lower endless heat belt 26, and the above three pieces inside the lower endless heat belt 26 are arranged inside the upper endless heat belt 29. Three pressure rollers are arranged at a position facing the pressure roller in a pair.

  Each of these pressure rollers presses the endless heat belt toward the facing portion. As a result, the sheet 16 or 8 that has been V-folded or Z-folded is sandwiched between the lower endless heat belt 26 and the upper endless heat belt 29 and conveyed, while being applied to the surface to which the powder adhesive 17 is applied (surface in the sheet 16). c, the surface A and the surface F in the sheet 18 and the opposing surfaces (the surface d in the sheet 16 and the surfaces B and E in the sheet 18) are respectively pressed. Note that another oil application roller 32 is disposed in contact with the outer end of the upper endless heat belt 29 on the downstream side, which will be described later.

  Subsequently, the sheet 16 or 18 is conveyed to the shape ordering unit 8. In the shape adjusting unit 8, the sheet 16 or 18 is corrected in skew, aligned in the conveyance width direction, and further conveyed to the cutting / separating unit 9.

  The cutting / separating section 9 is cut along a cutting line 13 or 15 shown in FIG. 2 (a) or FIG. 2 (b) by a slitter, and two independent V-folding or Z-folding postcards 11 ′ or 18 Complete as'.

  The completed two V-fold or Z-fold crimped postcards 11 'or 18' are detected by the sheet sensor 33 disposed in the vicinity of the carry-out port and are stored in the discharge storage unit 10 while being counted. The

Here, the configuration and operation of the adhesive application unit 5 will be further described.
FIG. 5 is an enlarged view showing the configuration of the adhesive application unit 5. In FIG. 5, the same components as in FIG. 1 are given the same numbers as in FIG. FIG. 5 also shows a doctor blade 34 not shown in FIG.

  Since the transfer pattern (the shape of the adhesive application part) is determined in advance when the powder adhesive 17 is transferred and applied to the pressure-sensitive postcard, the adhesive application part 5 of this example is like a conventional electrophotographic system. In addition, it is configured based on the idea that fine control by the exposure head for the photosensitive drum as a transfer device is unnecessary.

  That is, according to the adhesive application method of this example, the same powder as the toner is transferred and applied as an adhesive, but the electrophotographic exposure head, the photosensitive drum, the initialization charger, etc. Since the used transfer process can be abolished, the cost of the transfer part can be reduced.

  As shown in FIG. 5, the adhesive application unit 5 includes the powder adhesive container 19, the adhesive supply roller 21, the intermediate transfer drum 22, and the transfer roller 24 shown in FIG. A doctor blade 34 that is in sliding contact with the peripheral surface of the adhesive supply roller 21 is disposed inside the portion 19.

  The doctor blade 34 regulates the powder adhesive 17 accommodated in the powder adhesive accommodating portion 19 to a constant layer thickness and applies a certain weak potential to the powder adhesive 17 while adhering the powder adhesive. The agent 17 is adhered to the peripheral surface of the adhesive supply roller 21.

  The adhesive supply roller 21 electrostatically transfers the powder adhesive 17 to a predetermined application portion formed on the peripheral surface of the intermediate transfer drum 22. The intermediate transfer drum 22 transfers (applies) the powder adhesive 17 in cooperation with the transfer roller 24 onto the adhesive application surface of the sheet 16 or 18 conveyed as shown by an arrow d.

  The surface of the intermediate transfer drum 22 is covered with an insulating layer 35, and an application part 36 and a non-application part 37 are provided thereon. The application part 36 and the non-application part 37 are prevented from contacting each other by the insulating layer 35.

  FIG. 6A is a cross-sectional view of the intermediate transfer drum 22 according to the second embodiment, and FIG. 6B is a perspective view showing an appearance and an operation state thereof. As shown in FIG. 4B, the application portion 36 of the intermediate transfer drum 22 is formed in an adhesive application shape corresponding to the required application surface of the pressure-sensitive postcard, as shown in FIG. In addition, a bias voltage Vb is applied.

  The non-application part 37 is formed so as to surround the periphery of the application part 36 as shown in FIG. 2B, and a bias voltage Vc is applied as shown in FIG. . Thus, a potential difference is provided between the application part 36 and the non-application part 37.

Further, a bias voltage Va is applied to the adhesive supply roller 21 as shown in FIG. 5A, and the doctor blade 34 is in sliding contact as shown in FIG.
The powder adhesive 17 shown in FIG. 5 enters between the adhesive supply roller 21 and the doctor blade 34 by the rotation of the adhesive supply roller 21 in FIG.

  The bias voltage relationship described above is set to Vc <Va <Vb. For example, when Vc = −700 V, Va = −250 V, and Vb = −50 V are set, the adhesive supply roller 21 has a low negative potential with respect to the non-application portion 37, that is, a positive polarity with respect to the non-application portion 37. The portion 36 has a high negative potential, that is, the polarity is negative with respect to the coating portion 36.

  As described above, the powder adhesive 17 charged to a weak negative potential is applied via the adhesive supply roller 21 to the application unit 36 and the adhesive supply roller 21 having a lower negative potential, that is, a positive polarity than the adhesive supply roller 21. It is attracted to the application part 36 by being attracted by the electric field formed therebetween.

  Since the non-application portion 37 has a higher negative potential than the adhesive supply roller 21, that is, the polarity is negative, the electric field formed between the non-application portion 37 and the adhesive supply roller 21 is opposite to the above and is charged to a weak negative potential. Since the powder adhesive 17 receives repulsion from the electric field, it does not adhere to the non-applied portion 37.

  A positive bias voltage is applied to the transfer roller 24 (see FIGS. 1 and 5). The powder adhesive 17 adsorbed to the application part 36 of the intermediate transfer drum 22 is drawn toward the transfer roller 24 side having a higher positive polarity than the application part 36, and between the intermediate transfer drum 22 and the transfer roller 24. Is transferred to a sheet 16 or 18 that passes through.

  FIG. 6B shows that the outer circumferential length of the intermediate transfer drum 22 is ½ the length C of the sheet 16, and the length along the circumference of the coating portion 36 is the length of the coating portion of the powder adhesive 17. B. Accordingly, the intermediate transfer drum 22 rotates twice until the sheet 16 passes through after contacting the intermediate transfer drum 22. In other words, two rows of application portions 40 of the powder adhesive 17 and unapplied portions 38 of the powder adhesive 17 are formed along the conveyance direction d on one sheet 16.

  In this case, the intermediate transfer drum 22 rotates when it is in contact with the sheet 16, and stops when it is not in contact. For this reason, in this example, before the sheet 16 reaches the intermediate transfer drum 22, for example, the sheet sensor 3 detects the position of the sheet 16 and synchronizes with the rotation of the intermediate transfer drum 22. The position shift of the 17 application scheduled portions 40 is prevented.

  If the distance between the sheets is set to n times the outer peripheral length of the intermediate transfer drum 22, and the bias voltage of the coating portion 36 of the intermediate transfer drum 22 is set to the voltage Vc during that time, the rotation of the intermediate transfer drum 22 is stopped. There is no need to let them.

  In the above embodiment, the outer circumferential length of the intermediate transfer drum 22 is ½ of the sheet length. However, the shape of the coating portion is matched to the adhesive application shape of the sheet, and the outer circumferential length of the drum is set to the sheet. It may be the same as the length, or may be 1 / n of the sheet length.

(Embodiment 3)
FIG. 7A is a cross-sectional view of the intermediate transfer drum 22 of the adhesive application unit 5 in the pressure-bonding postcard making apparatus as Embodiment 3, and FIG. 7B is a perspective view showing the appearance and operation state thereof. The intermediate transfer drum 22 shown in FIGS. 7A and 7B has the same main body configuration as that in FIG. 6A, but is configured so that the applied voltage is not always constant and can be switched.

  That is, as shown in FIG. 7 (a), the electrode 39 conducting to the application part 36 includes a switch 41, and the bias voltage applied to the application part 36 can be switched between the voltage Vb and the voltage Vc. It has become. Thereby, the state of the application part 36 can be selected from the state of the application part and the state of the non-application part.

  In this configuration, when the outer circumferential length of the intermediate transfer drum 22 is ½ of the sheet length, as in the case of the second embodiment, for example, as shown in FIG. In the first rotation after contact with the transfer drum 22, when the bias voltage Vb is made conductive to the coating unit 36, the powder adhesive 17 is adsorbed to the coating unit 36, and this is transferred to the sheet 16, so that the powder The application portion 40 of the body adhesive 17 is formed on the sheet 16.

  Thereafter, when the bias voltage of the application unit 36 is switched to the voltage Vc, the powder adhesive 17 is not adsorbed to the application unit 36 in the next second rotation, and therefore, even if the sheet 16 is in contact with the application unit 36, the application is scheduled. The portion 40 is not formed on the sheet 16, and the selective unapplied portion 42 to which the powder adhesive 17 is not applied similarly to the unapplied portion 38 can be formed in the same size as the portion 40 to be applied.

  If the switching of the bias voltage is appropriately performed, the intermediate transfer drum 22 can be kept rotating regardless of the presence or absence of the sheet 16, power consumption due to the inrush voltage of the intermediate transfer drum driving unit, and the electrode Can be reduced.

  Further, if the switching of the bias voltage is performed at an interval of 2 to 1, normal application can be performed in which both the two bonded surfaces without provisional folding are applied to the Z-fold pressure-bonding postcard sheet 18.

  As shown in FIGS. 8A and 8B, the intermediate transfer drum 22 is rotatably supported by the frame 43 of the adhesive application unit 5. The intermediate transfer drum 22 includes a gear 44 at one end (right side in the figure), and is rotationally driven via the gear 44 by a drive system (not shown) of the adhesive application unit 5.

  The intermediate transfer drum 22 has conductive shafts 45 and 46 formed at both ends instead of the cored bar. The conducting shaft 45 is in sliding contact with the charging plate 47 fixed to the frame 43 on the outer peripheral surface of the end portion on the outer side of the drum, and on the outer peripheral surface of the end portion on the inner side of the drum, via the spring 48 that is a connecting member. Is electrically connected.

  Further, the conduction shaft 46 is in sliding contact with the charging plate 49 fixed to the frame 43 at the outer peripheral surface of the outer end of the drum, and is not connected to the outer peripheral surface of the inner end of the drum via the spring 51 which is a connecting member. It is electrically connected to the application part 37.

  With this configuration, even when the intermediate transfer drum 22 is stopped and rotating, the non-applying portion 37 is always connected via the spring 51, the conductive shaft 46, the charging plate 49, and the electrode 52 as shown in FIG. Connected to the bias voltage Vc power source, the application unit 36 is selectively connected to the bias voltage Vc or Vb power source via the spring 48, the conduction shaft 45, the charging plate 47, the electrode 39, and the switch 41.

As a result, as shown in FIG. 7 (b), it is possible to arbitrarily form the application scheduled portion 40 and the selectively unapplied portion 42 on the sheet 16. The same applies to the sheet 18.

12C, the non-application portion 58 and the belt-like pad 62 are connected, and the application portion 56 and the application portion 57 are connected to the belt-like pad 62 by the insulating layer 59. Insulated from.

  The strip pad 62 is always in contact with the fixed contact spring 65. A bias voltage Vc is always conducted to the fixed contact spring 65. That is, the bias voltage Vc is always applied to the non-application part 58. Therefore, the non-application part 58 does not adsorb the powder adhesive 17, and the powder adhesive 17 is not transferred to the sheet 16 from parts other than the application part 56 and the application part 57.

  Further, as shown in FIG. 12 (d) by a sectional view taken along the line II, the coating part 57 and the strip-shaped pad 63 are connected, and the coating part 56 and the non-coated part 58 are separated by the insulating layer 59. Insulated from.

By the way, as described above, the crimping postcard making apparatus 1 shown in FIG. 1 is configured such that the large-capacity discharge storage apparatus 11 can be connected to the lower part thereof. This has been conceived because a paper discharge tray for storing a large amount of paper discharge has not been found in the past, and this is not enough to accommodate, for example, a large-capacity advertising postcard or the like. Is. Hereinafter, the large-capacity paper discharge storage device 11 will be described as a seventh embodiment.

  FIG. 15 is a diagram illustrating a configuration example of a large-capacity paper discharge storage device 11 according to the seventh embodiment. As shown in the figure, in the large-capacity paper discharge storage device 11, the sheet 18 or 16 (not shown) discharged from the paper discharge port 77 of the crimping postcard making device 1 naturally falls on the guide 78 and is discharged. The inside of the paper discharge cassette 81 of the apparatus 79 is dropped and stacked.

  The capacity of the sheets 18 or 16 stacked on the paper discharge cassette 81 is detected based on the set height, weight, number of sheets, and the like. When the set predetermined height, weight, or number is detected, the lid 82 that has been rotated up until then is rotated downward.

  The lid 82 rotated downward inhibits the sheet 18 or 16 from dropping into the paper discharge cassette 81 and guides the conveyance of the sheet 18 or 16 toward the adjacent paper discharge cassette 83.

  As a result, the sheet 18 or 16 passes through the upper surface of the lid 6 and is dropped and stacked in the adjacent paper discharge cassette 83. It is detected that the sheets 18 or 16 stacked on the paper discharge cassette 83 have reached an allowable amount based on the set height, weight, number of sheets, or the like as described above.

  By this detection, the lid 84 that has been rotated up until then is rotated downward. The lid 84 rotated downward prohibits the sheet 18 or 16 from dropping into the paper discharge cassette 83 and guides the conveyance of the sheet 18 or 16 toward the adjacent paper discharge cassette 85.

As a result, the sheet 18 or 16 is guided by the lid 84 and conveyed to the next paper discharge cassette 85.
As described above, according to this example, the three discharge cassettes 81, 83, and 85 are installed in parallel, and the sheet 18 or 16 is automatically fed into each discharge cassette. The sheets 18 or 16 can be stored in the cassette device without being stacked high.

In addition, since it can be installed under the crimping postcard producing apparatus main body 1, there is an advantage that a large-capacity paper discharge apparatus can be mounted without increasing the installation area of the entire apparatus.
FIG. 16 is a diagram illustrating another configuration example of the large-capacity paper discharge storage device in the crimping postcard making apparatus according to the seventh embodiment. In the large-capacity paper discharge storage device 11 ′ shown in the figure, the sheet 18 or 16 discharged from the paper discharge port 77 of the main body 1 naturally falls on the guide 78, and the inside of the paper discharge cassette 87 of the paper discharge device 86.

  The predetermined height, weight, or number of sheets 18 or 16 stacked on the paper discharge cassette 87 is detected here, and the lid 88 that has been rotated up until then is rotated downward. . The lid 88 rotated downward inhibits the sheet 18 or 16 from dropping into the paper discharge cassette 87 and guides the conveyance of the sheet 18 or 16 toward the adjacent paper discharge cassette 89.

The sheet 18 or 16 passes over the lid 88 and is transported toward the adjacent paper discharge cassette 89 by a transport driven roller 91 attached to the upper surface of the paper discharge cassette.
The conveyed sheet 18 or 16 is dropped and stacked in the paper discharge cassette 89 as it is. Here again, the predetermined height, weight, or number set in the same manner as described above is detected, and the lid 92 that has been rotated up until then is rotated downward. The lid 92 rotated downward inhibits the sheet 18 or 16 from dropping into the paper discharge cassette 89 and guides the conveyance of the sheet 18 or 16 toward the adjacent paper discharge cassette 93.

The sheet 18 or 16 is conveyed to the next paper discharge cassette 93 by the conveyance driven rollers 94 and 95 attached to the upper surface of the paper discharge cassette.
According to this example, since the sheet is transported to the adjacent paper discharge cassette by the transport driven roller, the upper surface of the paper discharge cassette can be formed horizontally without forming an inclined surface for natural fall. The capacity can be maximized.

  FIG. 17 is a diagram showing still another configuration example of the large-capacity paper discharge storage device in the crimping postcard making apparatus according to the seventh embodiment. In the large-capacity paper discharge storage device 11 ″ shown in the figure, the sheet 18 or 16 discharged from the paper discharge port 77 of the main body 1 naturally falls on the guide 78, and the inside of the paper discharge cassette 97 of the paper discharge device 96.
