Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact letter producing device, and more specifically, it is obtained by folding two or three cut sheets into
The present invention relates to a contact letter production device for continuously producing contact letters by adhering the folded portion to a layer with a peelable double-sided adhesive film.

[0002]

2. Description of the Related Art Conventionally, a contact letter has been used in which a sheet is folded and its folded portion is temporarily adhered, as if it were a single card. Such a close contact letter is used for various notices, etc., because the inside information cannot be seen until the bonded folded portion is expanded and the privacy protection is excellent. In addition, a postcard-sized contact letter can be mailed at a lower postcard fee than a postcard, has more information than a regular postcard, and is more cost-effective, so it is also used for direct mail.

[0003] Such a contact letter uses a special adhesive paste that does not adhere unless very large pressure is applied to temporarily adhere folded sheets, and a special adhesive that can be separated into two layers. Some use a double-sided adhesive film.

In the former contact letter using a special adhesive paste, printing or data entry is performed on a dedicated paper having the adhesive paste applied on the surface in advance, and then the sheets are folded so that the adhesive surfaces overlap with each other. Apply very large pressure to bond the bonding surfaces. The adhesive force between the adhesive surfaces thus bonded is relatively weak, and the folded paper can be easily spread. However, re-adhesion usually requires too much pressure to be re-adhesive. A contact letter using such a special adhesive paste can be manufactured at a relatively low cost, but since printing is performed on the adhesive glue of the paper, high-quality printing cannot be performed and the adhesive force is not weakened. You can only print or enter data. In addition, the entered data may be transferred or tampered with on the opposite side. Further, since the adhesive strength of the dedicated paper coated with the adhesive paste is apt to deteriorate due to aging and cannot be stored for a long period of time, the dedicated paper must be used, that is, adhered, in a relatively short period of time.

On the other hand, in the latter contact letter 1 using a special double-sided adhesive film, as shown in FIG. 2, after the adhesive film 2 is inserted into the folded portion 7 of the paper 6, as shown in FIG.
Both sides of the folded paper 6 6a. Adhesive film 2 between 6b
Glue with sandwiching. As shown in FIG. 1, the adhesive film 2 includes two film layers 3a and 3b adhered to each other with a relatively weak adhesive strength that can be peeled by hand, and heat sensitive adhesive layers 4a and 4b on both sides thereof, that is, outside. Have. The adhesive letter 1 is manufactured by heat-bonding the adhesive layers 4 and 4b of the adhesive film 2 to the facing surfaces 6x of the both sides 6a and 6b of the folded paper 6. Since the adhesive strength with which the adhesive layers 4a and 4b adhere to the paper sheet 6 is greater than the adhesive strength between the film layers 3a and 3b, when the both sides 6a and 6b of the folded paper sheet 6 are unfolded, the adhesive film 2 forms the film layer 3a. , 3b are separated at the joint surface 3x to separate the two separation layers 2a, 2b. The film layers 3a and 3b once peeled off do not adhere to each other thereafter. The release layers 2a, 2b of the adhesive film 2 are generally transparent, and the recipient is aware of the release layers 2a, 2b of the adhesive film 2.
Through the, the printing, entry data, etc. of the adhesive surface of the paper 6, that is, the opposite surface 6x, can be viewed. The contact letter 1 using the adhesive film 2 is generally more expensive than the case where the above-mentioned special adhesive paste is used, but high-quality printing is possible on the entire sheet 6 and the entered data and the like are transparent. Since it is covered with the film 2, it is difficult to be tampered with and has excellent water resistance.

By the way, the contact letter 1 using such an adhesive film 2 is generally manufactured by using continuous form paper. However, it is difficult to perform high-quality printing on continuous foam paper. Further, there are only a limited number of printers equipped with a continuous form printing machine capable of printing continuous form paper. On the other hand, a cut paper cut into a predetermined size and shape can easily perform high-quality printing, and the printing place where printing can be performed is not limited. Therefore, a contact letter manufacturing apparatus that manufactures contact letters using cut paper has been earnestly desired. As a conventional technique, there was a contact letter manufacturing device using cut paper, but in the conventional device using cut paper, it is necessary to laminate an adhesive film on the cut paper and prepare in advance,
It took a lot of work and the processing efficiency was not so good. Therefore, there is a strong demand for a contact letter manufacturing apparatus that improves the processing efficiency by using cut paper as paper and performing the step of overlapping the adhesive film on the paper and the step of folding the paper simultaneously at the same time.

In order to realize such a contact letter manufacturing apparatus with improved processing efficiency, cut sheets, that is, sheets are continuously fed one by one by a sheet feeding device, and a continuous sheet-shaped adhesive film is superposed on the sheets. A contact letter manufacturing device having the above-mentioned configuration can be considered.

However, in the conventional general paper feeder, even if the paper is supplied at regular intervals, the gap before and after the supplied paper, that is, the paper interval, varies within a certain range. Therefore, if the paper feed interval is made too small, the front and back paper sheets may overlap with each other and interfere with each other, which may cause inconvenience in a subsequent process. Therefore, the paper feed interval must be increased to some extent so that the front and rear papers do not overlap. However, as the paper feed interval increases, the paper gap also increases, and the throughput of the contact letter device also decreases accordingly. In addition, since there is a continuous sheet-shaped adhesive film in the gap between the paper sheets, the paper gap portion is discarded, and the adhesive film is wasted a lot. Therefore, there is a strong demand for a contact letter producing apparatus that improves the processing efficiency by reducing the distance between the sheets supplied by the sheet feeding device in a subsequent process and then cutting the sheet and the adhesive film.

[0009]

Therefore, a first technical problem to be solved by the present invention is to use a cut sheet as a sheet, and to simultaneously perform a step of stacking an adhesive film on the sheet and a step of folding back the sheet at the same time. It is to provide a contact letter manufacturing device for performing the following. A second technical problem to be solved by the present invention is to solve the first technical problem, and
It is an object of the present invention to provide a contact letter manufacturing apparatus in which the distance between supplied sheets is reduced in a subsequent step and then the sheet and the adhesive film are cut.

[0010]

In order to solve the above technical problems, according to the present invention, there is provided a contact letter manufacturing apparatus having the following configuration.

That is, the contact letter manufacturing apparatus manufactures a contact letter by sandwiching the adhesive film between the folded portions of the sheet folded in two or three and adhering the folded portions. The adhesive film has adhesive layers on the front and back surfaces of the base material layer. The adhesive of this adhesive layer is not only a general adhesive that adheres without any special treatment if it comes into contact,
For example, a special adhesive such as a heat-sensitive adhesive that adheres when heated or a pressure-sensitive adhesive that adheres when pressure is applied is also included. Further, for example, a general adhesive may be used for the adhesive layer on the back surface of the adhesive film, and a pressure-sensitive adhesive may be used for the adhesive layer on the front surface, or a combination of various adhesives may be used. . The adhesive film can be separated into two layers by being separated by the base material layer. The contact letter manufacturing device includes a sheet feeding unit, a stacking unit, a cutting unit, and an adhering unit.
The sheet feeding means continuously feeds sheets of a predetermined size and shape one by one with an interval provided. The laminating means folds the paper supplied by the paper feeding means while folding the paper 180 degrees along a fold line extending in the transport direction, and in the middle of folding the paper 180 degrees, the adhesive film in the form of a continuous sheet. Is continuously supplied to the folded portion of the paper, and the adhesive film is sandwiched in the folded portion of the paper. The cutting means cuts the sheet into a predetermined size together with the adhesive film sandwiched by the laminating means. The adhesive means activates the adhesive film, that is, the adhesive layer of the adhesive film exerts an adhesive action by a treatment such as pressing and / or heating, and the adhesive layer on the front and back surfaces of the adhesive film is Adhere to the above paper. For example, when the adhesive layer of the adhesive film contains a general adhesive, the adhering means adheres the adhesive layer of the adhesive film to the paper such that the paper and the adhesive film are in close contact with each other. When the adhesive layer of the adhesive film contains a heat-sensitive adhesive, the bonding means heats the heat-sensitive adhesive layer of the adhesive film and bonds the heat-sensitive adhesive layer of the adhesive film to the paper by heat fusion. . When the adhesive film contains a pressure-sensitive adhesive, the adhering means applies pressure with the adhesive film sandwiched between the sheets to adhere the pressure-sensitive adhesive layer of the adhesive film to the sheet.

In the above structure, the paper having a predetermined size, that is, the cut paper is supplied to the laminating means by the paper feeding means. The laminating means folds 180 degrees until one of the sheets overlaps the fold line, and, in the process of folding the sheet, sandwiches the adhesive film between one side and the other side of the sheet, that is, between the folds. Since the sheets are supplied to the laminating means with a space provided therebetween, the front and rear sheets do not interfere when the sheets are folded back. With the adhesive film overlaid on one side of the sheet, and the other side of the sheet overlaid, the sheet and the adhesive film are cut into a predetermined size by the cutting means and adhered by the adhering means to complete the contact letter. Note that the paper and the adhesive film may be temporarily bonded before being cut. For example, in the case of using an adhesive film containing a pressure-sensitive adhesive layer, the paper and the adhesive film are pressed at an intermediate pressure to temporarily bond them, then cut by a cutting means, and then pressed to a final pressure by the bonding means. You may make it adhere | attach completely. In the apparatus having the above structure, the paper is continuously supplied and processed. In the completed contact letter, when the folded portion is expanded, the adhesive layer of the adhesive film is peeled off at the base layer of the adhesive film while being adhered to both sides of the paper. Since the adhesive film is usually transparent, it is possible to see the information printed and entered inside the contact letter, that is, the fold.

Therefore, the apparatus having the above construction can use the cut sheet as the sheet and can simultaneously perform the step of superposing the adhesive film on the sheet and the step of folding back the sheet simultaneously.

In the above construction, the adhering means is arranged next to the cutting means, but the cutting means may be arranged next to the adhering means. That is, the adhering means activates the adhesive film sandwiched by the laminating means to adhere the adhesive layers on the front and back surfaces of the adhesive film to the paper. The cutting means cuts the paper, to which the adhesive layers on the front and back surfaces of the adhesive film are adhered by the adhering means, into a predetermined size together with the adhesive film.

In each of the above constructions, the fold line of the paper widely includes a starting point when the paper is folded back. For example, even if the perforation is made by intermittently cutting the paper, cut the paper halfway in the thickness direction. It may be a cut line. The fold line of the sheet may be formed in a separate step in advance, but preferably, it is configured as follows.

That is, the stacking means further comprises a crease imparting device for imparting a crease extending in the transport direction to a predetermined position of the paper while transporting the paper fed from the paper feed section.

In the above structure, it is possible to form the folds on the paper by the crease imparting device before the laminating means folds the paper. Therefore, the contact letter can be manufactured without forming a fold line on the paper in advance.

Preferably, the laminating means comprises a first carrying means, a second carrying means, a first carrying tip position detecting means, and
A second conveyance rear end position detection means and a conveyance control means are provided. The first carrying means receives the paper from the paper feeding means and carries the paper. The second transport means receives the sheet from the first transport means and transports the sheet. The first transport leading end position means is the first transport leading edge paper that is the closest to the second transport means, that is, the paper that is transported by the first transport means, that is, the most of the paper that is transported by the first transport means. The leading edge position of the leading edge of the paper is detected. The second conveyance rear end position detection means is the second conveyance rear end paper which is the paper conveyed by the second conveyance means and is closest to the first conveyance means, that is, the paper conveyed by the second conveyance means. The trailing edge position of the rearmost sheet is detected. The transport control means includes the first transport tip position detecting means and the second transport tip position detecting means.
Based on the detection signal of the conveyance rear end position detection means, the first
The conveyance of the first conveying unit and the second conveying unit is controlled so that the conveying leading sheet catches up with the second conveying trailing sheet.

In the above structure, the transfer control means is the first
Based on the detection signals of the transport leading end position detecting means and the second transport trailing end position detecting means, the distance between the first transport leading edge sheet and the second transport trailing edge sheet, that is, the sheet is transferred from the first transporting means to the second transport trailing edge sheet.
The conveyance of the first conveying means and the second conveying means is controlled so that the first conveying front end sheet catches up with the second conveying rear end sheet while detecting the interval when the sheet is transferred to the conveying means. That is, the sheet interval when being conveyed by the second conveying means is the first
It should be shorter than the sheet interval when it is transported. With this, the second conveying unit can send the sheet to the cutting unit at a shorter interval than when the sheet is supplied by the supply unit.

Therefore, the apparatus having the above-mentioned structure can cut the paper and the adhesive film after the distance between the supplied papers is reduced in the subsequent step.

In the above construction, if the conveying speed of the first conveying means is made faster than the conveying speed of the second conveying means, it is possible to shorten the sheet interval without stopping the conveying. Further, the cutting means can be configured to cut the paper and the adhesive film in a continuous carrying state without stopping the paper carrying, for example, by using a rotary cutter.

Preferably, the transport control means of the stacking means always controls the transport of the first transport means and the second transport means so that the sheet transport speed is the same.
On the other hand, the transport control means appropriately stops the transport of the second transport means, and while the transport of the second transport means is stopped, the transport of the first transport means is driven to perform the first transport. The conveyance of the first conveyance means and the conveyance of the first conveyance means is controlled so that the conveyance leading sheet catches up with the second conveyance trailing edge sheet up to a predetermined interval.

In the above structure, the carrying control means always controls the first carrying means and the second carrying means to be synchronously driven and stopped at the same carrying speed. On the other hand, the transfer control means appropriately stops the transfer of the second transfer means,
The transport of the first transport means is driven even while the transport of the transport means is stopped so that the spacing between the sheets can be reduced to a predetermined spacing when the sheet is transferred from the first transport means to the second transport means. . After the paper interval reaches the specified interval, the first
After stopping the transportation of the transportation means, the first transportation means and the second transportation means
The transport speed of the first transport means and the transport speed of the second transport means are increased by restarting the transport of the transport means synchronously or by restarting the transport of the second transport means while continuing the transport of the first transport means. Try to be the same.

In the above structure, the first and second conveying means always have the same conveying speed, which facilitates the control of the conveying of the first and second conveying means. Further, it is possible to smoothly transfer the sheet from the first transporting unit to the second transporting unit. That is,
When the front side of one sheet is conveyed by the second conveying means and the rear side is conveyed by the second conveying means, there is no difference in speed between the front and rear, so that wrinkles occur in the sheet or the sheet is pulled. There is nothing to do.

Preferably, the conveyance control means of the laminating means is interlocked with the cutting drive of the cutting means, and the second control means
The transportation of the transportation means is stopped.

In the above-mentioned structure, the conveyance of the second conveying means is driven / stopped in association with the driving / stopping of the conveyance corresponding to the cutting drive of the cutting means, the sheet interval in the second conveying means and the sheet in the cutting means. The transfer control means can control the transfer of the second transfer means so that the interval is the same. Such control is
Relatively simple. Further, the above-described operation for making the paper interval in the second carrying means shorter than the paper interval in the first carrying means is performed while the carrying of the second carrying means is stopped in association with the cutting drive by the cutting means. Because you can
The device operates efficiently. Furthermore, the cutting means can be configured to stop the conveyance of the paper and the adhesive film and perform the cutting, and it is possible to easily cope with various paper cutting dimensions by changing the setting of the control parameter of the cutting timing.

The above-mentioned first conveying front end detecting means and second conveying rear end detecting means of the stacking means can also be constructed by providing a plurality of position detecting sensors in a predetermined range between the first conveying means and the second conveying means. However, preferably, it is configured as follows.

That is, the first conveying front end detecting means and the second conveying rear end detecting means of the stacking means are provided on the first conveying means and the front and rear ends of the sheets conveyed by the first conveying means. The leading edge position of the first leading edge sheet is detected based on a detection sensor that detects the passage of the edge, and a detection signal of the detection sensor and a sheet transportation speed detection signal of the first transporting means and / or the second transporting means. And position calculating means for obtaining the rear end position of the second transport rear end sheet.

In the above structure, the position calculating means integrates the conveying speed of the sheet, that is, the sheet conveying speed of the first conveying means after the detecting sensor detects the leading edge of the sheet, thereby detecting the leading edge of the sheet and the detecting sensor. The distance to the position can be determined. Similarly, after the detection sensor detects the trailing edge of the sheet, the position calculating section integrates the sheet conveying rate of the sheet, that is, the sheet conveying rate of the first conveying section or the second conveying section, to thereby detect the trailing edge of the sheet. The distance between the position and the detection sensor position can be determined. That is, the leading edge position of the first transport leading edge sheet and the trailing edge position of the second transport trailing edge sheet can be obtained. Only one detection sensor is required,
Simpler configuration.

Preferably, the laminating means comprises a film feeding means for feeding the adhesive film on one side of the fold line of the sheet between the first feeding means and the second feeding means. . The second conveying means of the stacking means includes a suction conveyor belt that receives the sheet from the first conveying means and conveys the sheet while adsorbing one lower surface to the fold of the sheet.

In the above structure, since the film feeding means is provided between the first feeding means and the second feeding means, the adhesive film is fed onto the sheet fed by the second feeding and is fed by the first feeding. Substantially does not come into contact with the paper. Since the adhesive film and the paper are adsorbed and conveyed by the suction conveyor belt of the second conveyance, both speeds are the same. Therefore, the adhesive film is smoothly conveyed in a state of being in close contact with the paper without rubbing with the paper.

Preferably, the laminating means comprises a first conveying means including an upper roller group and a lower roller group, a second conveying means including a suction conveyor belt, and a folding bar means. The upper roller group and the lower roller group of the first conveying means receive the paper from the paper feeding means and act on one of the folds of the paper to convey the paper. The suction conveyor belt of the second conveying means receives the sheet from the first conveying means and conveys the sheet while adsorbing the one lower surface to the fold of the sheet. The folding bar means includes a substantially linear first bar provided above the suction conveyor belt of the second conveying means, a pressing plate, and a substantially linear second bar. Then, at least one lower roller of the lower roller group of the first conveying unit has a bulge portion on the other side with respect to the fold line of the sheet. In the first bar of the folding bar means, the first bar obliquely intersects the fold line of the sheet, and the upstream end of the first bar is the other side of the fold line of the sheet. The first bar is arranged so that its downstream end is on one side of the fold line of the sheet. The pressing plate of the folding bar means is generally the first pressing plate.
It is configured such that it extends along one side of the sheet along the bar and the outer edge of the pressing plate extends along the fold line of the sheet. The second bar of the folding bar means is such that the second bar is substantially orthogonal to the sheet conveying direction, and
The upstream end of the second bar is in the vicinity of the downstream end of the first bar, and the downstream end of the second bar is on one side with respect to the fold line of the sheet and away from the fold line. Arranged as it is. Then, after the other of the sheets is raised by the bulging portion of at least one of the lower rollers of the lower roller group of the first conveying means, that is, after being folded up by about 90 degrees, the folding bar is It is configured to be laid down by means, that is, folded back by approximately 180 degrees.

In the above structure, one of the folds of the sheet is conveyed by the upper roller group and the lower roller group of the first conveying means. On the other hand, the other side of the sheet is in a natural state with respect to the fold, but when it reaches the lower roller having the bulge on the other side of the sheet with respect to the fold, the other lower surface of the sheet comes into contact with the bulge. Along the fold line, up to about 90 degrees,
Can be launched. At this time, one of the sheets is sandwiched between the upper roller group and the lower roller group, and the conveyance direction does not shift. In order to start the other side of the paper, it is possible to provide another roller dedicated to the start-up, or to provide a protruding member that contacts the lower surface of the other side of the paper, but if the lower roller is provided with a bulge, Simpler configuration.

The sheet of which the other is started is then conveyed while one of the sheets is adsorbed by the suction conveyor belt of the second conveying means. On the other hand, the leading end side of the first bar comes into contact with the lower surface of the other side of the sheet, and the other side of the sheet is tilted by 90 degrees or more along the first bar that is obliquely arranged with respect to the fold line.
At this time, one side of the sheet is adsorbed by the suction conveyor belt and pressed by the pressing plate, and the outer edge of the pressing plate is along the fold line of the sheet, so the sheet is folded back at the fold line without shifting the conveying direction. In other words, the paper does not bend except the folds. Next, as the paper is transported,
The other side of the sheet contacts the second bar, and the other side of the sheet is laid down on one side of the sheet and folded down.

Therefore, one of the sheets can be continuously and smoothly folded back over the other, and the adhesive film can be sandwiched between the folded portions.

Preferably, the laminating means is a film supply means for supplying the adhesive film on one side of the paper with respect to the fold of the paper between the first conveyance and the second conveyance. Prepare The second conveying unit of the stacking unit further includes a holding roller that receives the sheet conveyed by the suction conveyor belt, and sandwiches the sheet from above and below to convey the sheet.

In the above structure, the adhesive film is not caught by the upper roller group and the lower roller group of the first conveying means, is conveyed while being adsorbed by the suction conveyor belt of the second conveying means, and is pulled by the sandwiching roller. Therefore, when the adhesive film is stacked on one side of the paper, the adhesive film is not forced to be pinched from above and below,
On the upstream side of the sandwiching roller, the adhesive film naturally follows the upper surface of one side of the paper without meandering or wrinkling. In addition, the sandwiching roller conveys the sheet with the adhesive film sandwiched in the folding portion and creates a crease at the fold. Therefore, the sandwiching roller makes it possible to fold the sheet more completely, and it is easier to maintain the folded state.

The present invention also includes the invention of a contact letter manufacturing method.

That is, the contact letter manufacturing method has an adhesive layer on the front and back surfaces of the base material layer between the folded parts of the sheet folded in two or three and is separated by the above base material layer to form two layers. It is a method of producing a contact letter by sandwiching an adhesive film that can be peeled off and adhering the folded portion. The adhesive of the adhesive layer of the adhesive film is not particularly limited. That is, it may be a general adhesive that adheres without any special treatment, or a special adhesive such as a heat-sensitive adhesive or a pressure-sensitive adhesive. The adhesive contact letter manufacturing method includes a paper feed step of continuously feeding sheets of a predetermined size, that is, cut sheets of paper one after another with a gap therebetween and aligning the orientations one by one. While folding the sheet 180 degrees along the fold line extending in the transport direction, while continuously folding the sheet 180 degrees, the continuous sheet-shaped adhesive film is continuously supplied to the folding portion of the sheet, A stacking step of sandwiching the adhesive film between the folded portions of the paper, a cutting step of cutting the paper together with the adhesive film sandwiched in the stacking step into a predetermined size, and a predetermined step in the cutting step. An adhesive step for activating the adhesive film cut into dimensions to adhere the adhesive layers on the front and back surfaces of the adhesive film to the paper. And a flop. And
The stacking step includes a sheet spacing adjusting step of transporting the front and back sheets at different speeds and adjusting the spacing between the front and back sheets.

In the above structure, cut paper can be used as paper. In the laminating step, the step of stacking the adhesive film on the paper and the step of folding the paper are continuously performed at the same time. Further, the sheet spacing adjustment step included in the stacking step allows the sheet spacing to be adjusted to be convenient for the subsequent processing. At which point in the stacking step the sheet spacing adjustment step is executed is arbitrary. That is, even if the sheet spacing adjusting step is executed at the beginning of the stacking step and then the sheet folding or the like is executed, the sheet folding operation or the like may be performed while the sheet stacking step is being performed. The paper gap adjusting step may be executed by interrupting it, or further, the paper gap adjusting step may be executed at the end of the laminating step, that is, after the adhesive film is sandwiched between the folded portions of the paper. . Paper spacing adjustment step,
It includes at least one of the case of adjusting by making the paper interval short and the case of adjusting by making it long. For example, in the case of adjusting by making the paper interval short, the paper interval can be adjusted so that the long paper interval becomes short, and the waste of the adhesive film can be reduced. When adjusting by increasing the paper spacing, avoid problems by widening the paper spacing to the appropriate paper spacing when the paper spacing is too short or even partially overlapping each other. can do. Therefore, by adjusting the paper spacing,
The processing efficiency can be improved.

In the above construction, the order of the cutting step and the adhering step may be reversed. That is, in the adhering step, the adhesive film sandwiched in the laminating step is activated to adhere the adhesive layers on the front and back surfaces of the adhesive film to the paper. In the cutting step, the paper having the adhesive layers on the front and back surfaces of the adhesive film bonded by the bonding step is cut into a predetermined size together with the adhesive film.

Next, at step # 26, the second processing section 50 completely folds the sheet 12 in two by the action of the pressing plate 54, the first bar 55, the second bar 56, and the sandwiching roller 57. That is, the transport side 12a of the paper 12
Is conveyed by the suction belt conveyor 52 while its upper surface is being pressed by the pressing plate 54. At this time,
The lower surface of the rising side 12b of the sheet 12 folded by the folding roller 36 of the first processing unit 30 first contacts the tip 55a side of the first bar 55, and the sheet 12 is conveyed along the first bar 55. It is folded back to 12a up to about 90 degrees. next,
The upright side 12b of the sheet 12 is further folded back to the transport side 12a of the sheet 12 by the second bar 56, and the sheet 12 is folded back along the fold line 14 by about 180 degrees. Then, the paper 12 is pinched by the gripping rollers 57 from above and below, so that the paper 12 is completely bent. In this way, the second processing unit 50
The paper 12 that is conveyed is gradually folded back in order.

Next, the sheet conveying operation such as steps # 20 to # 24 will be further described with reference to FIGS. 10 and 11. FIG. 10 shows the first main motor 38, the second main motor 58, and the cutter motor that drive the first processing unit 30, the second processing unit 50, and the cutting unit 60, and the first sensor 31 and the second sensor 51. It is a timing chart figure. 11 (I) to 11 (IV) are diagrams schematically showing the conveyance state of the sheet 12 at each time point.

Generally, as shown in FIG.
The paper interval A of the paper 12 supplied from 0 in the first processing unit 30 is relatively wide and varies to some extent. On the other hand, in the second processing unit 50, the first main motor 31 and the second main motor 51 are driven so that the paper interval B is small and substantially constant. That is, the first
The main motor 38 and the second main motor 58 are controlled so that the sheet conveying speeds of the first processing unit 30 and the second processing unit 50 are the same in order to smoothly deliver the sheet 12. The second main motor 58 has a cutting unit 60.
The sheet motor 12 is intermittently stopped to cut the sheet 12, and the cutter motor is driven while the second main motor 58 is stopped. The first main motor 38 is basically driven in synchronization with the intermittent driving of the second main motor 58, but the second main motor 58 is stopped in order to cut the leading end side of the second transport leading edge paper 96. Only while the first main motor 3
Numeral 8 drives so as to close the sheet interval.

Specifically, as shown in FIG. 10, the second main motor 58 and the cutter motor, which drive the second conveying section 50 and the cutting section 60, are the rear end 98 of the cutting paper 98.
The interval B between y and the leading edge 96x of the second transport leading edge paper 96 is set to the second
Based on the output signal change 101 due to the detection by the sensor 51, the signals are driven in synchronization with the reference numerals 121, 122, 12
As indicated by reference numerals 3, 131, 132, 133, the sheet 12 and the adhesive film 2 are cut along the cutting lines 16a, 16b, 16c by intermittently stopping or driving three times at predetermined intervals.

That is, as shown in FIG. 11 (I), when the trailing edge 98y of the cut sheet 98 passes through the second sensor 51 and the trailing edge 101a of the detection signal 101 is detected, a predetermined time elapses and then reference numeral 121 is given. As shown, the second main motor 58 stops. As a result, as shown in FIG. 11 (II), the trailing edge of the cutting paper 98 is positioned at the cutting portion 60 and stopped. Then, as indicated by reference numeral 131, the cutter motor is driven to trim the rear end side of the cutting paper 98 along the rear cutting line 16c.

Next, the second main motor 58 has the reference numeral 12.
After being driven for a predetermined time as indicated by 9, it is stopped as indicated by reference numeral 122. As a result, as shown in FIG. 11 (III), the leading edge side of the subsequent second transport leading edge sheet 96 is positioned at the cutting section 60 and stopped. The time indicated by reference numeral 129, that is, the time during which the second main motor 58 is driven between the first stop and the second stop, is the paper interval B and the leading edge cutting from the leading edge 16x to the leading cutting line 16a. Make a decision based on your generation. The sheet interval B is obtained each time from the interval between the falling edge 101a and the rising edge 101b of the output signal 101 of the second sensor 51. On the other hand, since the leading edge cutting margin is a constant value determined at the time of printing the paper, it is set first according to the paper 12 used. While the second main motor 58 is stopped for the second time, as indicated by reference numeral 132, the cutter motor is similarly driven to cut the leading edge side of the second transport leading edge paper 96 along the leading edge cutting line 16a.

At this time, the second main motor 58 is
The second stop is continued until the reduction of the sheet interval between the transport leading edge sheet 92 and the second transport trailing edge sheet 94 is completed. The first main motor 38 normally stops in synchronization with the stop of the second main motor 58, but continues to be driven only during the second stop of the second main motor 58. That is, the first main motor 38 continues to be driven, and as shown in FIG. 11 (IV), the first conveyance leading edge sheet 92 having the leading edge 92x detected by the first sensor 31 is located before the sheet 92. The trailing edge 94y of the second transport trailing edge sheet 94 stopped at the second processing unit 50
The first transport leading edge sheet 92 and the second transport trailing edge sheet 94 are positioned at a predetermined interval B, and the driving is stopped.

Specifically, in FIG. 10, the second signal is generated by the falling edge 102a of the output signal 102 of the first sensor 31.
The passage of the trailing edge 94y of the conveying trailing edge sheet 94 is detected, and the passage of the leading edge 92x of the succeeding first conveying leading edge sheet 92 is detected by the rising edge 102b of the output signal 102 of the first sensor 31. The second transport trailing edge sheet 94 is the second main motor 5
It is conveyed by the second processing unit 50 until 8 stops.
Therefore, based on the time from the falling edge 102a of the output signal 102 of the first sensor 31 to the stop 122a of the second main motor 58, the position of the first sensor 31 is used as a reference, and the rear end of the second conveyance trailing edge sheet 94 is conveyed. The position of the end 94y can be obtained. The first main motor 38 detects the passage of the leading edge 92y of the first transport leading edge sheet 92 by the first sensor 31, and then the leading edge 92x of the first transport leading edge sheet 94 changes to the trailing edge 94y of the second transport trailing edge sheet 94. Is driven for a predetermined distance B from the position to the position X on the rear side, that is, on the upstream side. First
The position of the leading edge 92x of the transported leading edge paper 92 is determined by the first sensor 3
The position from the rising edge 102b of the first output signal 102 to the stop 122a of the first main motor 38 can be determined using the position of the first sensor 31 as a reference.
As a result, the first transport leading edge sheet 92 corresponds to the time from the second stop start 122a of the second main motor 58 to the stop start 112a of the first main motor 58.
Will catch up with the second conveyance trailing edge sheet 94, and the sheet interval A corresponding to the time between the falling edge 102a and the rising edge 102b of the first sensor 31 will be shortened to the sheet interval B. The first main motor 38 and the second main motor 58 are servo motors, and the timing belts 39 and 59 allow the first transport unit 30 and the second transport unit 5 to operate.
If 0 and the feed roller 64 of the cutting unit 60 are driven, it is easy to obtain the leading edge 92x position of the first transport leading edge sheet 92 and the trailing edge 94y position of the second transport trailing edge sheet 94. Note that the minimum value of the sheet interval B is the second sensor 5
It is determined by the sheet interval detection resolution of 1.

In order to restart the driving of the second main motor 58 after the second stop, it is usually possible to restart the driving of the first transport leading edge sheet 96 after the cutting of the leading edge side of the second transport leading edge sheet 96 is completed. And a sheet gap shortening operation between the second conveyance rear end sheet and the sheet. However, even if the cutting of the paper 96 is completed and the drive of the second main motor 58 can be restarted, if the paper interval shortening operation is not completed due to the absence of the output signal change 102 of the first sensor, Resuming the drive of the second main motor 58 until the paper interval shortening operation is completed 12
Delay 2b. Then, if the paper interval shortening operation is not completed even after delaying by a predetermined time, a predetermined alarm process is executed.

When the driving of the second main motor 58 is restarted, the second main motor executes the stop 123 for the third time in accordance with the sheet cutting length, and the cutter motor is driven,
Along the intermediate cutting line 16b of the sheet, the second transport leading edge sheet 9
Cut 6 Then, the above operation is repeated to cut the rear end side of the 22nd transport sheet 96.

In the case of a reciprocal postcard, a paper 12 having a width approximately 1.5 times as large as that of a double-fold postcard is used, and a ⅓ portion 12a of the paper 12 is folded back to the central portion 12a and adhered, and the communication side 12a, 12b It is doubled, and the duplicating side 12c remains single. In the case of the three-fold postcard, the sheet 12 having a width of approximately 1.5 times is passed through the apparatus once to be bonded as in the reciprocal postcard shown in FIG. 12 (II), and then as shown in FIG. 12 (III). Then, the paper 12 is turned upside down, turned backside down, passed through the apparatus 10 again, folded in a Z shape, and bonded. Further, in the case of the envelope size, one envelope is manufactured from one sheet 12 and, as shown in FIG. 12 (IV), the leading edge cutting line 16a and the trailing edge cutting line 1 of the sheet 12 are manufactured.
