Description

The present invention relates to a turning system used by connecting to a printing device, a scanner device, or the like.

There is a demand for printing on the next sheet immediately after printing on one sheet cut out from a bundle of paper, and each sheet bound after binding multiple sheets with the required contents pre-printed. Of these, there is a demand for additional printing of specified company names, store names, advertisements, etc. in a part of the specified sheet sheet as needed, and immediately after printing on one sheet sheet, the next sheet In order to enable printing following the leaves, a technique for immediately cutting and moving each leaf immediately after printing is required. The present invention also relates to a "non-contact automatic paper turning system" using a new technology in which a substance other than gas does not physically contact the entire surface of the printed surface so as not to stain the printed surface. Is.

Conventionally, a technique of cutting, rolling, or moving using a roller has been used to move a sheet of paper cut out from a bundle of paper immediately after printing. When a roller is used, the entire surface of the paper is pressed by the roller, cut out and rolled while rotating, and further conveyed, so that the printed portion of each leaf may be rubbed in a state where the ink is not dried. Therefore, a technique for emergency drying before starting rubbing the paper immediately after printing has been developed, and as is generally well known, it is a technique for instant drying and coating by making full use of UV printing, precoating, and postcoating techniques. However, these technologies may have high operating costs such as the need to use expensive ink in addition to the initial cost, and require complicated and expensive mechanisms, so their adoption is limited. .. In the present invention, in order to prevent ink rubbing, which is useful for application fields that cannot be used because the above-mentioned instant drying technique is expensive and complicated, a paper cutting technique immediately after printing and a paper transport technique are used. The present invention relates to a new technology in which the operation of all the mounted mechanisms does not rub the entire printed surface of each sheet, and does not directly rub the paper immediately after printing with ink.

In addition, recent inks have been improved, and as long as the paper immediately after printing is stacked so as not to directly rub the paper immediately after printing and the paper is not physically impacted, stains on the printed surface, so-called The problem of show-through does not occur. Therefore, a technology for stacking papers at the end of transportation in an operation without physical impact is important, and a non-contact automatic turning system that takes countermeasures against this is important.

Addition to a part of the area from a booklet or calendar on which one side of the paper is bound When cutting out a sheet immediately after printing, a mechanism that uses a roller as a means to separate the first sheet from the second and subsequent sheets has been put into practical use. Has been done. In the page turning mechanism of the passbook disclosed in Utility Model Document 1, a roller is used for cutting out and turning the paper immediately after printing. In addition to this example, many commercially available printers use a plurality of rollers for separating, moving, and transporting paper for cutting out before and after printing. When a roller is used, the surface of the paper is rubbed during rotation, so if this print area is rubbed immediately after printing, ink stains will occur and the print quality will deteriorate, so in the case of printing booklets and calendars that require precise print quality. Even if the roller must be installed so as not to rub the printed part immediately after printing, or even if additional printing is performed only in a part of the area, "Install the roller only in the place where this printed part is not rubbed." Is acceptable. ”In some cases, there were major restrictions. In addition, rollers are generally "regular replacement parts", and for these rollers that are also used in commercial printers, printer companies provide information on "regular replacement parts" to users. According to this information, it is explained that the replacement life of various rollers is about 200,000 sheets of paper such as A4 size plain paper and high-quality paper. The first problem to be solved is to realize a method that can avoid the restrictions imposed when using rollers, especially in the case of "name printing" of calendars, such as twice or four times as much as A4 paper. Even when the size is large and the replacement life is short, or when the number of printed sheets is large, it is possible to avoid deterioration of the quality of the additionally printed printed part and greatly reduce the labor and cost of replacement instead of the roller technology. It is to realize a non-contact automatic turning system that can perform cutting and feeding operations without using rollers for the cutting mechanism, turning and feeding mechanism.

Patent Document 1 discloses an example in which the first sheet of paper is separated from the second and subsequent sheets by a vacuum suction nozzle. In this embodiment, a part of the paper to be cut out is sucked by the vacuum suction nozzle. Therefore, if the area immediately after printing is sucked, the printed portion is rubbed and stains are generated, so that printing cannot be performed in a place where the suction nozzle contacts. was there. The second problem to be solved is to establish a non-contact automatic turning system that can cut out, turn, and convey paper without being restricted by using the suction nozzle, and on both the left and right sides of the paper. It is possible to print to the edge or to the edge of the edge. Further, in Patent Document 1, after adsorbing the paper printed by the vacuum suction nozzle and separating it from the second and subsequent sheets, the gas blown out from the "compressed air nozzle" is hit against the back surface of the paper to blow off the paper. Examples of moving are disclosed. In this embodiment, the soft and light paper often causes wrinkles on the paper, resulting in deterioration of the quality of the printed matter. In addition, it was difficult to blow off the thick, heavy, and stiff paper. The third problem to be solved is to establish a technology that can transport thin or thick paper instead of the conventional technology that blows out the paper by hitting the blown air against the back surface of the paper in order to avoid deterioration of the quality of the paper to be conveyed. This is to establish a non-contact automatic paper turning system.

Conventionally, in order to prevent deterioration of print quality even if the paper is rubbed immediately after printing, technology development for instant drying using UV printing or precoating technology has been carried out. In order to use these technologies, expensive equipment is required, special ink is required, and there are problems such as high temperature around the equipment. In addition, as with the ink nozzle that ejects printing ink, it is necessary to install a nozzle for applying precoating agent and eject the precoating agent immediately before the spot where the ink is ejected to immediately absorb the ink and suppress bleeding. It has become. This mechanism uses a control mechanism that maintains the same fineness as the ink head, and sprays a precoat agent immediately before each dot on which the ink is placed to correspond to all the ink dots, resulting in high operating costs. There were problems such as the precision required of the control mechanism. The fourth problem to be solved by the present invention is that as an alternative to expensive and complicated technology such as instant drying using UV printing or precoating technology, a mechanism such as paper cutting, rolling, and transport is non-contacted. It is to establish a non-contact automatic turning system for paper. In recent years, inks have been improved, and even cheap inks that can be used normally are stacked so that the printed surface of the paper immediately after printing is not directly rubbed and pressed, or the paper immediately after printing is not physically impacted. As far as the limit is concerned, stains on the printed surface and so-called show-through problems do not occur. In the present invention, the above-mentioned instant drying technique is expensive and complicated, so that it is not possible to use it. For application fields that cannot be used, in order to prevent ink rubbing, which is useful for use together with the improving ink technique, paper is cut out immediately after printing. Established a new technology in which the operation of the mechanism and all the mechanisms of the paper transport mechanism do not rub the entire printed surface of each sheet, and therefore do not directly rub the paper immediately after printing with fresh ink. However, the printed printing area and all the above mechanisms operate in a non-contact manner, and the paper at the end of transfer does not have a physical impact, and is placed on a table for accommodating this paper or on paper that has already been transferred. It is to realize a non-contact automatic turning system that can be stacked on paper.

Japanese Patent Application No. 2015-011822 is a "paper turning device for turning paper included in a booklet", in which the turning paper to be turned is attached and the attached portion to which the turning paper is attached is outside the booklet. It is displaced so as to move inward of the peripheral edge and in a direction away from the booklet, or in a direction away from the edge of the booklet with the turning paper to be turned attached attached. A gap forming member that rotates to form a gap between the turning paper and another paper included in the booklet, and a member other than the gap forming member after the gap is formed by the gap forming member are used. Disclosed is a paper turning device including the flipping means for turning the paper. As a means for forming the adhered portion, a means for using an adhesive tape or air suction is disclosed. A fifth problem to be solved by the present invention is that after the gap is formed by the gap forming member for forming the gap and the gap forming member, the flipping paper is turned over using a member other than the gap forming member. It is to establish a non-contact automatic turning system that can suppress the increase in cost due to the need for separate means. In addition, in the above-mentioned Japanese Patent Application No. 2015-011822, a gap forming member such as an adhesive tape or a negative pressure due to suction of air is used as a means for cutting out the sheet-fed paper, and the gap forming member is directly connected to the paper to be cut out. Examples of contact are disclosed. A sixth problem to be solved by the present invention is to establish a non-contact cutout technical means capable of opening a gap without contacting the paper to be cut out and the gap forming member with anything other than gas. As described above, the conventional automatic turning device has a number of restrictions, so that its widespread use is limited. Therefore, even now, manual transportation and turning work are still used at many work sites. In particular, the single-wafer transportation and turning work of the calendar is performed manually using a flatbed offset printing machine, and there is still a risk of getting caught in the hands and the situation where harsh work is forced continues. It is also a big issue to be solved.

The present invention relates to a conventional automatic paper rolling machine, as described above, a first problem related to the use of a roller, a second problem related to the use of a suction nozzle, a fourth problem related to the use of an expensive high-speed drying technique, and In order to solve the sixth problem related to the direct contact between the paper to be cut out and the gap forming member, it is necessary to utilize the buoyancy due to the pressure difference generated by the Bernoulli effect caused by the flow of gas, and the viscosity of the gas. A means to combine the physical phenomena of gas, such as the frictional force generated between gas and paper, the retention characteristics of gas, and the pseudo-dividing effect of the space created by the flow of gas, that is, the air curtain effect, is applied to the paper rolling system. However, the printed surface of the paper comes into contact only with the gas, and all the mechanisms of the turning system do not come into direct contact with the paper to construct a non-contact automatic turning system to solve the above-mentioned plurality of problems. It should be noted that the above-mentioned retention characteristic means that the gas is unlikely to flow or move when there is no pressure difference between a certain enclosed space and the external space. Paper balloons are one example. In addition, the suction chuck used for the cutting or gap opening operation performed in the first half of the automatic turning system also maintains the non-contact operation during the cutting operation by using the non-contact suction chuck that utilizes the Bernoulli effect, and the paper suction location. As a means of solving the problem, the paper slides without making physical contact with all the mechanical members including the suction chuck due to the gas existing between the paper and the suction pad even when the paper moves with the movement of the paper. ing. Next, the third means for solving the problem will be described. Conventionally, high-pressure gas compressed by an air compressor is guided to a "compressed air nozzle" by a vinyl pipe or the like via an air regulator or the like, and blown out from this "compressed air nozzle" having a plurality of minute spouts having a diameter of about 1 mm. A high-pressure gas characterized by concentration and strength was used, but since it is used in place of this conventional technology or in combination with this conventional example, the gas sent from an electric blower that takes advantage of the characteristic of increasing air volume is used in PVC pipes, etc. The gas is generated by the flow of gas using a "blower air blower" that has a structure that uniformly blows gas from a large number of large outlets or one very large outlet, although the pressure is small and the force is weak. As a means of solving the problem, a technique of utilizing the buoyancy due to the pressure difference generated by the Bernoulli effect and utilizing the viscosity of the gas and the frictional force generated between the gas and the paper is used. In addition, the period immediately before the transfer of each sheet of paper is completed is caused by the flow of gas by installing the "blower air blower" that maintains the flow of gas on the upper or side surface of each sheet. The characteristic of suppressing the sudden drop of each single leaf due to the buoyancy due to the pressure difference generated by the Bernoulli effect is used as a problem-solving means. Further, a method of maintaining a non-contact operation not only on the printed surface but also on the back surface side thereof is also used as one of the problem-solving means. Further, as a fifth problem-solving means, an example in which the conventional rotating member is formed by winding an adhesive tape is shown, and an example in which the adhesive is exposed on the outer peripheral surface is disclosed. Further, as another example, a means for vacuum adsorption is exemplified. In the present invention, by using a non-contact suction chuck that utilizes the Bernoulli effect instead of the adhesive or vacuum suction, a technique of sharing this non-contact suction chuck even during the operation of the entire non-contact cutting machine is used as a problem-solving means. ing. As a supplement, most of the high-pressure air ejected from the plurality of non-contact suction chucks and the "compressed air nozzle" and the gas ejected from the "blower air blower" are blown onto the printed surface of each sheet immediately after printing. Since the ink is operated to flow, a technique for exerting an auxiliary effect of ink drying immediately after printing is also used as an auxiliary means for solving a fourth problem related to ink drying.

As described above, the non-contact automatic turning system of the present invention can be applied to application fields such as name-printing of booklets and calendars, which is an example of a field in which emergency drying of ink is difficult. Immediately after printing the name on this calendar, the name will be printed on the next page, so it is necessary to move the paper immediately. With the non-contact automatic turning system of the present invention, the printed surface immediately after printing is not directly rubbed, and the printing unit that is additionally printed without using expensive equipment and mechanisms such as UV drying and precoating that require operating costs. It is possible to avoid deterioration of the quality of the product and to reduce the labor and cost of replacement. In addition, the conventional automatic turning system has not been widely used due to the restrictions explained in paragraphs 0006, 0007, and 0008, and the automation of the industry as a whole has been delayed, and the manual turning work is still performed at the work site. By realizing the non-contact automatic turning system of the present invention that can eliminate the restrictions of the conventional automatic turning system, it is possible to bring about the effect of contributing to the elimination of a harsh work site. Furthermore, in the manual work that is still performed in many name printing, the paper is grasped with one hand, cut out, rolled, and moved, and the next calendar is carried in with the other hand. At that time, it was difficult to maintain the uniformity of the movement of the paper, and the paper sometimes wrinkled. For this reason, the information page on the calendar on the homepage of the National Uchiwa Folding Fan Calendar Council has a note saying, "Because humans grab it by hand and turn it over, it will have wrinkles (paper habits)." On the other hand, the non-contact automatic turning system of the present invention does not rely only on high-pressure gas ejection and vacuum technology, which are characterized by concentration and strength, but also pipes such as PVC pipes to the gas sent from an electric blower that takes advantage of the feature of increasing air volume. A "blower air blower" that has a structure that uniformly blows gas from a large number of large outlets and one very large outlet, although the pressure is small and the force is weak, is also used, and is well-balanced in the left-right direction of the paper. Since the cutting operation and the conveying operation are performed, it is a great effect that wrinkles can be avoided even on thin paper that is prone to wrinkles, unlike the case of manual work. According to the present invention, this is an example of a field in which it is difficult to urgently dry ink. As described above, after collating and binding a plurality of sheets on which necessary contents are printed in advance, a designated company name and store name are used as necessary. In response to the demand for "name-printing" such as calendars that print additional prints on a part of each leaf later, when moving the sheet immediately after this additional printing, the print quality of the paper does not deteriorate. , It is possible to provide a transport mechanism at low cost regardless of the type of paper, such as thick or thin. As the work other than the paper, it is possible to provide a mechanism capable of applying a film-like work, a thin plate work, or the like to non-contact cutting. In addition, expensive equipment and operating costs are required even when the printed paper is cut out immediately after printing on the entire area of the paper one by one on a plurality of sheets and continuously printed on the next sheet. It has the effect of being able to provide a mechanism that prevents ink show-through without using a mechanism such as UV drying or precoating. Further, the printing machine used together with the present invention operates as a master for timing control, and the non-contact automatic turning system of the present invention operates as a slave. It can be said that it is also a great effect that the internal operation of this non-contact automatic turning system that operates as a slave can be finely adjusted by a computer control mechanism within an allowable range determined by the operation timing of the printing machine.

Except for the fixing device that presses the paper binding margin or its vicinity, all the mechanisms of the booklet and calendar paper cutting mechanism immediately after printing and the paper conveying mechanism when cutting is completed are made of substances other than gas. A non-contact automatic turning system using a new means that enables non-contact operation without directly rubbing the entire surface of the printed surface, and further enables the use of a method of maintaining non-contact operation not only on the printed surface but also on the back surface side thereof. It was realized. Hereinafter, examples of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a configuration diagram showing the entire non-contact automatic turning system 90 according to the first embodiment (Example 1) of the present invention. This non-contact automatic turning system 90 is composed of a non-contact cutting machine 91 and a non-contact transporting machine 93 for transporting the cut-out completed paper as shown by an arrow 97 after the cutting operation is completed. Each paper at the end is configured to have a transport mechanism portion that can be stacked on top of the paper that has already been fed, with no physical impact. Further, a computer control mechanism 98 is installed in this non-contact automatic turning system, and all the mechanisms of the non-contact cutting machine 91 and the non-contact carrier 93 are systematized so as to be electronically controlled.

FIG. 2a is a top view of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a second embodiment (Example 2) of the present invention. In FIG. 2a, four large arrows located vertically and horizontally indicate the direction of the paper. The vertical arrow 36 on the left side indicates the front side, and the arrow 37 on the right side indicates the rear side. Further, the horizontal arrow 38 on the lower side indicates the right side surface, and the arrow 39 on the upper side indicates the left side surface. A binding margin 17 bound with metal fittings or thick paper is provided on the top side of the top and bottom of the top paper 40, and this top side is the rear side. On the other hand, the ground side 18 is called a fore edge in the calendar, and this side is the front side. In addition, a non-contact suction chuck machine 60 is installed in the center. The upper side of the non-contact suction chuck machine 60 is the left side surface 39, and the lower side is the right side surface 38.

Next, FIG. 2b is a cross-sectional view (1) of the new non-contact cutting machine 91 used in the non-contact automatic turning system 90, as viewed from the front side, according to the second embodiment (Example 2) of the present invention. In a certain FIG. 2b, the non-contact suction chuck machine 60 is in the upper standby position (first height). The vertical movement of the non-contact suction chuck machine 60 is performed by the left air cylinder 56 installed on the left side and the right air cylinder 57 installed on the right side. This vertical movement can be performed by a mechanism in which one air cylinder is installed in the center, and it is also possible to use a motor as power. A bundle of paper with a binding margin is placed on the support base 1, and the top-level paper 40 of the bundle is displayed separately. Further, in order to prevent double feeding of paper when cutting out paper, paper holding machines 54 and 55 for holding the remaining bundle of paper after cutting out the top-level paper are installed on the left and right. From this state, the non-contact suction chuck machine 60 is lowered as the air cylinder is lowered. At this time, gas is ejected from the "compressed air nozzle (left)" 65 installed on the left side and the "compressed air nozzle (right)" 66 installed on the right side. Gas between the top paper of the bundle of paper and other paper remaining at the bottom. Can be provided to assist the non-contact suction operation of the non-contact suction chuck machine 60 of the top-level paper by injecting the paper to release the crimping between the papers. In the specification of this patent, when the term "compressed air nozzle" is used, high-pressure air compressed by the compressor is sent to the nozzle via a vinyl pipe or the like via an air regulator or the like as described above. It means a "compressed air nozzle" that strongly injects high-pressure air from a plurality of minute spouts having a diameter of about 1 mm.

FIG. 3 is a cross-sectional view (2) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a second embodiment (Example 2) of the present invention, as viewed from the front side. In FIG. 3, the non-contact suction chuck machine 60 is in the position where the lowering is completed, and the non-contact suction operation is started. The lowering completion position of the non-contact suction chuck machine 60 is set to a position (second height) where the negative pressure generation region 59 by the non-contact chuck reaches the top paper 40. In FIG. 3, the time point at which the non-contact suction chuck machine 60 reaches the second height where the negative pressure region 59 is in contact with the top paper 40 is shown.

FIG. 4 is a cross-sectional view (3) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a second embodiment (Example 2) of the present invention, as viewed from the front side. In FIG. 4, the non-contact suction chuck machine 60 is stopped at the second height, but the top-level paper is lowered due to the buoyancy due to the pressure difference generated by the Bernoulli effect caused by the gas flow. It shows the position where it is attracted to the chuck machine 60 and rises to the position indicated by 41. At this time, the negative pressure generated by the Bernoulli effect is blocked by the adsorbed top-level paper, does not act on the paper at the bottom, and does not cause double feeding. After that, the top-level paper is further raised from the position of 41 by the raising operation of the left and right air cylinders to complete the cutting operation. At this time, in order to prevent the lower paper from being double-fed due to the negative pressure generated between the top paper and the stack of paper remaining at the bottom due to the sudden rise of the top paper, the left paper press (left) 54 is used immediately before the start of this rise. It shows that the paper holding machine (right) 55 on the right side is operated so as to hold the paper bundle 2 remaining at the bottom. In order to prevent further double feeding at this time, operations such as injecting gas that functions as an airbrush are performed on the paper remaining at the bottom, or "compression" installed on the left and right for high-speed suction of gas remaining between the bottom paper. The air nozzles "65 and 66" may be operated. In the case of this high-speed suction, high-speed suction of gas is possible by piping via a device called an ejector. The left side paper retainer (left) 54 and the right side paper retainer (right) 55 perform an operation of pressing the paper bundle 2 remaining at the bottom, but this paper bundle 2 is unprinted paper and causes printing stains. Does not matter. Further, since the left and right paper presses sneak in without touching the lower side of the top paper immediately after printing, the print quality of the paper immediately after printing is not deteriorated. By such an operation, the top paper and the paper bundle remaining at the bottom are separated at the third height. Further, the left and right paper presses may be limited to an operation of sneaking in without touching the lower side of the top-level paper immediately after printing without performing an operation of pressing the unprinted paper downward.

FIG. 5 is a cross-sectional view (4) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a second embodiment (Example 2) of the present invention, as viewed from the front side. In FIG. 5, the non-contact suction chuck machine 60 rises in a state where the top paper is non-contact sucked by the raising operation of the left and right air cylinders, and the top paper reaches the position (fourth height) indicated by 42. It should be noted that the original first height may be returned instead of the fourth height. In addition, since the suction chuck used at the time of cutting also uses a non-contact suction chuck that utilizes the Bernoulli effect, even when the top-level paper shifts in the vertical direction when the non-contact suction position of the top-level paper rises to the 42 position. Due to the gas existing between the paper and the suction pad, the paper operates so as to take advantage of the sliding property without making physical contact with other than the gas. This misaligned behavior of paper always occurs when the paper is bundled by the binding margin, so mechanical gripping mechanism or vacuum suction causes tension with the binding margin of this paper and damages the paper. It may be given. When the above cutting operation is completed, the top-level paper at the position indicated by 42 stops the non-contact chuck suction operation, is separated from the non-contact cutting machine 91, and is separated from the non-contact cutting machine 91, and the next non-contact carrier 93 as shown in FIG. The state just before being handed over to is shown. During the operation of the cutting mechanism 91, the paper to be cut operates not only on the front side of the paper but also on the back side without physical contact with the non-contact cutting function from the start to the completion of cutting.

FIG. 6 is a cross-sectional view (1) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a third embodiment (Example 3) of the present invention, as viewed from the front side. In the third embodiment of FIG. 6, a central air cylinder 58 is added to the second embodiment of FIG. This purpose is to move the non-contact suction chuck machine 60 up and down by a small width with respect to the left and right air cylinders 56 and 57 that move up and down at once, and to move the non-contact suction chuck machine up and down small. In this cross-sectional view (1), the left and right air cylinders 56 and 57 are at the highest position, the center / cylinder 58 is also at the highest position, and the non-contact suction chuck machine 60 also stands by at the highest position (first height). The left and right air cylinders and the center / air cylinder both move to the lowest position of each cylinder operating range when the vehicle is in the operating state and then starts descending.

In FIG. 7, the left and right air cylinders 56 and 57 and the center / air cylinder 58 both move to the lowest position. Here, too, the lowering completion position of the non-contact suction chuck machine 60 is set to a position (second height) where the negative pressure generation region 59 by the non-contact chuck reaches the top paper 40. The non-contact suction chuck machine 60 reaches the lowest position, starts non-contact suction, and sucks at the position indicated by 40 by the buoyancy due to the pressure difference generated by the Bernoulli effect caused by the gas flow. Indicates the started state.

FIG. 8 is a cross-sectional view (3) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a third embodiment (Example 3) of the present invention, as viewed from the front side. In FIG. 7, the non-contact suction chuck machine 60 reaches the lowest position, starts non-contact suction and starts to rise, and in FIG. 8, the central air cylinder rises independently and the non-contact suction chuck machine is the third. It rises to a height of 3. This ascending position is set to an ascending position where a sufficient gap can be secured between the top-level paper at the position of 41 and the paper bundle 2 for the paper holding machines 54 and 55 installed on the left and right. Similar to the operation description of FIG. 3 in paragraph 0017 and the operation description of FIG. 4 in paragraph 0018, operations such as injection of gas that functions as an airbrush are performed on the paper remaining at the bottom to prevent double feeding before and after the start of adsorption. Alternatively, the "compressed air nozzles" 65 and 66 may be operated for high speed suction of the gas remaining between the lower sheets. In the case of this high-speed suction, high-speed suction of gas is possible by piping via a device called an ejector. Immediately after the completion of the entry operation of the paper presses 54 and 55 into the gap, the left and right air cylinders 56 and 57 move to the highest position. It is also possible to allow the paper presses 54 and 55 installed on the left and right sides to enter between the top-level paper and the paper bundle 2 during the period when the center / air cylinder of the previous term is independently raised to the third height. is there. In this case, it is also possible to start the ascending operation of the left and right air cylinders 56 and 57 at the final stage in which the central air cylinder in the previous period independently ascends to the third height. Similar to the description of FIG. 8 in paragraph 0018, this operation separates the top paper and the paper bundle remaining at the bottom at the third height, and the non-contact suction chuck machine stops at the third height. It can also be set to perform this disconnection while passing through the third height.

FIG. 9 is a cross-sectional view (4) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a third embodiment (Example 3) of the present invention, as viewed from the front side. In FIG. 9, the left and right air cylinders 56 and 57 move to the highest position, the non-contact suction chuck machine 60 also returns to the highest position (first height), and the top paper reaches the position indicated by 42. To do. Since the suction chuck used at the time of cutting also uses the non-contact suction chuck utilizing the Bernoulli effect as in the second embodiment of FIG. 5, when the non-contact suction position of the top paper rises to the position 42, the top paper Even when the paper shifts in the vertical direction, the gas existing between the paper and the suction pad causes the paper to operate so as to take advantage of the sliding property without making physical contact with anything other than the gas. This misaligned behavior of paper always occurs when the paper is bundled by the binding margin, so mechanical gripping mechanism or vacuum suction causes tension with the binding margin of this paper and damages the paper. It may be given. With the above, the cutting operation is completed, and the top-level paper at the position of 42 is separated from the non-contact cutting machine 91 by stopping the non-contact chuck, and as shown in FIG. 1, the next non-contact carrier 93 is shown by arrow 97. The state just before delivery is shown. Similar to the second embodiment of FIG. 5, during the operation of the cutting mechanism 91 of the third embodiment, the paper to be cut is physically not only the front side of the paper but also the back side from the start to the completion of the cutting. Works without contacting.

FIG. 10a is a cross-sectional view (2) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a fourth embodiment (Example 4) of the present invention, as viewed from the front side. With respect to the cross-sectional view (2) of the second embodiment of the non-contact cutting machine 91 of the present invention of FIG. 3 and the cross-sectional view (2) of the third embodiment of the non-contact cutting machine 91 of the present invention of FIG. As shown in the drawing, a left end non-contact suction chuck 69b and a right end non-contact suction chuck 69c capable of tilting the non-contact suction surface outward one by one are attached to both ends of the non-contact suction chuck machine 60. The lowering completion position of the non-contact suction chuck machine 60 shown in this figure includes the chucks 69b and 69c at both ends, and the cross-sectional view (2) and FIG. 7 of the second embodiment of the non-contact cutting machine 91 of the present invention shown in FIG. Similar to the cross-sectional view (2) of the third embodiment of the non-contact cutting machine 91 of the present invention, the position (second height) where the negative pressure generation region 59 by the non-contact chuck reaches the top paper 40. Set to.

FIG. 10b is a cross-sectional view (3) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a fourth embodiment (Example 4) of the present invention, as viewed from the front side. In FIG. 10b, the non-contact chucks 69 and 69c added to both ends are tilted only during the operation of opening a larger gap by the means described later in FIG. At this time, due to the change in the structure of the non-contact suction chuck machine 60, the negative pressure region is generated at the position 59 as in the example of FIG. 3 or FIG. 8, and the non-contact suction machine additionally installed causes the second. Negative pressure regions 59b and 59c of No. 2 are generated, and the top-level paper is slightly raised from the position 40 shown in FIG. 10a by this non-contact suction operation. Due to the generation of the second negative pressure regions 59b and 59c, both end portions of the top paper at the 40 position are bent upward, and more gaps are opened. After that, the installation angles of the non-contact chucks 69b and 69c are returned by the means described in paragraph 0027, and when all the bottom surfaces return to the positions of the second height, the top paper is returned to the original by the non-contact adsorption of the non-contact chucks. It reaches a horizontal state at a position slightly higher than the position of 40. Although it depends on the properties of the paper, the paper has a waist that prevents it from bending due to fiber or the like. The top-level paper outperforms the strength of the paper and bends according to the shape of the negative pressure region due to the non-contact suction of the non-contact chuck, but the paper in the lower bundle of paper is at the waist of the paper or between the papers in close contact. It does not bend due to the negative pressure of, and stays at the position of the paper bundle 2. In addition to the spread of the influence of the negative pressure region generated between the chuck and the top-level paper on the lower paper bundle by the Bernoulli chuck is blocked by the top-level paper itself, the non-contact suction chuck is a Bernoulli type. Unlike the vacuum chuck, vacuum penetration does not occur through the minute holes in the fiber of the top-level paper, and it is not attracted to the top-level paper and lifted. Summarizing the above, in the non-contact cutting machine, the force for preventing bending due to the strength of the waist of the top-level paper and the force remaining between the top-level paper and the paper immediately below it when a gap is generated. It operates under the condition that the force to increase the gap between the top-level paper that has been non-contact-adsorbed rises or bends is superior to the sum of the forces that try to keep the papers in close contact with each other due to negative pressure. This is a feature of the non-contact cutting machine of the present invention. Although the top-level paper bends, the gas blown out from the chuck exists between the non-contact suction chuck and the top-level paper and operates like an air mat, so no creases or scratches occur. .. As described above, the additional non-contact chucks installed at both ends of the non-contact suction chuck machine 60 can increase the operational stability of the paper gap. The paper retainers 54 and 55 can be easily inserted between the uppermost paper and the lower paper bundle that are opened wider.

FIG. 10c is a cross-sectional view (4) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a fourth embodiment (Example 4) of the present invention, as viewed from the front side. Here, only the central air cylinder 58 rises, the non-contact suction chuck machine reaches the third height, and the top paper rises to the position indicated by 41. The non-contact chucks 69 and 69c added to both ends may rotate and tilt so as to open a larger gap, and then reversely rotate and return during the period described in FIG. 10b, but during the period shown in FIG. 10c. When the central air cylinder 58 rises, it can be rotated in the reverse direction and returned. In FIG. 10c, the means for explaining the non-contact chucks added to both ends in parallel during the period when only the central air cylinder 58 rises and the non-contact suction chuck machine reaches the third height are described in the next paragraph 0027. As a result, the bottom surfaces of all the non-contact chucks are rotated in the reverse direction, and the bottom surfaces of all the non-contact chucks are leveled, and the center / air cylinder 58 is further raised by the amount of the rise to reach the third height. Since the position of the top-level paper moves to the height indicated by 41, the paper holders 54 and 55 installed on the left and right attach the non-contact chucks 69b and 69c added to both ends during the period described in paragraph 0025. The paper presser can also be inserted in the period shown in FIG. 10c instead of the period in which a large gap is opened by tilting. After the operation of inserting the paper holding machines 54 and 55 into the gap is completed, the left and right air cylinders 56 and 57 are raised, and the non-contact suction chuck machine is moved to the highest position of the fourth height. Alternatively, it may directly return to the original first height. As described in paragraph 0018, the presser operates so as not to come into contact with the top-level paper immediately after printing even if the lower paper that has not been printed is pressed during this period.

FIG. 11 is a cross-sectional view (3) of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a fifth embodiment (Example 5) of the present invention, as viewed from the front side. With reference to FIG. 11, the operation and mechanism when rotating and tilting the non-contact chucks 69b and 69c installed at both ends in FIGS. 10b and 10c and when performing the operation of returning to the original state will be described. There is a non-contact chuck 74 mounting base 76 having a left virtual fulcrum 72 at the bottom and a non-contact chuck 75 mounting base 77 having a right virtual fulcrum 73. The non-contact chucks 74 and 75 rotate along three concentric arcs indicated by dotted lines centered on the left virtual fulcrum 72 and the right fulcrum 73, respectively. In order to perform this rotational movement, each non-contact chuck uses two elongated holes formed along the arc in the mounting bases 76 and 77, respectively, and performs the rotational movement using the power of an actuator or the like. By this operation, buoyancy due to the pressure difference generated by the Bernoulli effect is newly generated at the positions indicated by 59b and 59c, and both ends of the top paper 40 are rolled up to generate gaps. By such a method, even when a larger gap is opened by the operation of the left and right non-contact chucks that rotate along an arc centered on the left virtual fulcrum 72 and the right virtual fulcrum 73, respectively. , The non-contact operation can be maintained over the entire printed surface of the paper. The non-contact chuck can be returned to the horizontal state before rotation by rotating the non-contact chuck in the reverse direction around the virtual fulcrums 72 and 73 by using the power of the actuator or the like. Further, as described in the operation of FIG. 10c in paragraph 0026, this reverse rotation operation can be performed in parallel with the operation in which only the center / air cylinder 58 is raised and the top sheet is raised to the position indicated by 41. ..

FIG. 12 is a top view of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to a fifth embodiment (Example 5) of the present invention. Similar to FIG. 2a described in paragraph 0015, in this figure the four large arrows indicate the direction of the paper. The vertical arrow 36 on the left side indicates the front side, and the arrow 37 on the right side indicates the rear side. Further, the horizontal arrow 38 on the lower side indicates the right side surface, and the arrow 39 on the upper side indicates the left side surface. FIG. 5 of an embodiment of Japanese Patent Application No. 2015-011822 described in paragraph 0009 shows a diagram in which adhesive tapes attached to rotating members are installed on the left and right side surfaces. Further, in FIGS. 9 (A) and 10 (A) of the embodiment of the above-mentioned Japanese Patent Application No. 2015-011822, suction air suction machines are installed on the left and right side surfaces of the calendar paper. With these conventional means, pulling easily occurs between the binding allowance of the paper and the suction machine using the adhesive tape or suction air, which may cause problems such as wrinkles on the sheet. On the other hand, Examples 2 to 4 shown in FIGS. 2 to 10c of the present invention disclose examples that do not cause such a problem. Further, the fifth embodiment of the present invention shows a technical means for realizing the non-contact cutting operation by an installation method that does not cause ink stains immediately after printing and does not cause deterioration of paper quality such as paper wrinkles. The explanation will be given below. First, the left virtual fulcrum 72 is installed next to the non-contact chuck 74 additionally installed on the left side 39 side, but in reality, it is installed at an angle of an oblique line segment 84 as shown in this top view. .. The line segment 84 is a line segment having an intercept on the side connecting 82A and 82D and the side connecting 82A and 82E of a right triangle having three points of 82A, 82D, and 82E as vertices. Similarly, the right virtual fulcrum 73 is installed next to the non-contact chuck 75 additionally installed on the right side 38 side, but in reality, as shown in this top view, it is installed at an angle of an oblique line segment 85. is there. The line segment 85 is a line segment having an intercept on the side connecting 82B and 82C and the side connecting 82B and 82E of a right triangle having the three points of 82B, 82C, and 82E as vertices. This condition is because the line segments 84 and 85 do not intersect on the calendar or each intersects the binding margin 17 and the fixture 6 to cause an abnormality such as wrinkles on the top sheet of the calendar. The length of the fixture is usually set shorter than the binding allowance, but if it is longer, the vertices 82D or 82C of the triangle may be both ends of the fixture, respectively. Along with this, the vertices 82A and 82B, which are right angles of the right triangle, move from both ends of the fixture 6 to the intersections where the perpendiculars drawn from the edges 18 of the calendar intersect with the edges. Summarizing the above, the non-contact chucks at both left and right ends that rotate around the two virtual fulcrums on the left and right are installed in the area of the top paper to be attracted when viewed from above, and the above when viewed from above. The two extension lines of the left and right virtual fulcrums do not intersect on the top paper, and the extension lines seen from above the two virtual left and right fulcrums of the top paper. It is a condition that the paper immediately after printing does not wrinkle if it does not intersect with the binding margin portion or the fixing portion of the paper by the fixing device that presses the top paper from above. Further, preventing the creases from colliding with each other and preventing the creases from colliding with the fixing device or the binding margin is a condition that does not hinder the operation of opening a gap, and is a condition for not causing wrinkles. By installing the non-contact chucks 74 and 75 added to the left and right side surfaces on the calendar paper, stable non-contact suction operation becomes possible, so that the line segments 84 and 85 intersect with the side sides, respectively. The angle depends on the size of the non-contact chuck and the installation position, but is set to about 5 degrees or more as a guide. Further, the left and right virtual fulcrums 72 and 73 perform the same operation even in the case of actual fulcrums. When the fulcrum can be installed at a position away from the area immediately after printing, if the paper immediately after printing and the actual fulcrum do not scratch the printing place immediately after printing even if the actual fulcrum comes into physical contact, the actual printing location is not scratched. You can also set up a fulcrum. Further, in the description of FIGS. 2 to 10c, "compressed air nozzles" from the left and right side surfaces once or a plurality of times during the period from immediately before to immediately after the gap opening operation of Examples 2, 3 and 4. It is also possible to inject air into the gap portion to release the crimping state between the papers due to static electricity, moisture, or the like.

FIG. 13 is a top view of a new non-contact carrier 93 used in the non-contact automatic turning system 90 of the present invention according to the sixth embodiment (Example 6) of the present invention. Example 6 of the non-contact carrier 93 is a non-contact suction chuck machine 60, a paper bundle 2 having a binding margin 17, a fixture 6, and a “blower air blower” installed on the front side, the left side surface side, and the right side surface side. It is composed of 51, 52 and 53, a pseudo-closed space 10, and the like. As shown in FIG. 13, when the upper surface of the sixth embodiment of the non-contact carrier 93 is viewed from a bird's-eye view, the non-contact suction chuck machine 60 of the non-contact cutting machine 91 rises to the uppermost position on the support base 1, and 42. You can see the top-level paper that has risen to the position. Since the rear surface side is pressed by the fixing machine 6 due to this rise, the edge portion 18 on the front side of this paper moves in the direction of the rear surface side 37 by moving to the position 42, and the lower side is behind the edge portion 18 on the rear surface side. A part of the edge side of the paper bundle 2 becomes visible. The configuration and operation of the pseudo-closed space 10 are as follows. First, there is a binding allowance 17 for binding a bundle of paper on the rear surface side, and a fixing device 6 for holding the bundle of paper 2 and the top-level paper of the bundle of paper from above is in the vicinity thereof. Further, the "blower air blower" 51 on the front side is installed above the support base and is provided with a plurality of slits and a plurality of blowout ports, and as shown by the arrow, the gas is blown diagonally downward toward the support base 1. To. These arrows are connected in series to indicate the flow of gas incident on the top-level paper and the bottom paper bundle 2 and the gas flow reflected by the top-level paper and the bottom paper bundle 2 and moving upward to the right. ing. The gas flow from the "blower air blower" 51 on the front side presses the vicinity of the edge of the paper downward. Next, the "blower air blower" 52 on the left side and the "blower air blower" 53 on the right side are installed at almost the same height as the support base, and have a plurality of slits, a plurality of outlets, or a large blower. One or a few ports are provided, and the gas is blown diagonally upward in the direction of the arrow attached to each, and the flow of gas blown out from the "blower air blower" 52 and 53 is like an air curtain. It functions as a pseudo air divider. Further, the uppermost paper is a wall on the upper surface side, and the support base and the lower paper are walls on the lower surface side. In this way, a pseudo-closed space 10 is formed in which six surfaces of the three-dimensional structure are closed, front, back, left, right, top, and bottom, and the gas confined in the pseudo-closed space 10 due to gas retention characteristics, friction characteristics, gas division characteristics, etc. It is possible to maintain or expand the inflated state like a "paper balloon" together with the gas blown from each "blower air blower" on the side and the right side. Further, in order to improve the closedness of the pseudo-closed space 10, a first gas blocking guide 61 and a second gas blocking guide 62 are installed on the left side surface, and a third gas blocking guide 62 is installed on the right side surface, if necessary. 63 and a fourth gas blocking guide 64 may be installed to enhance the shielding effect. The non-contact cutting machine 91 is shown in the non-contact suction chuck machine 60 utilizing a plurality of Bernoulli effects, but each embodiment of the non-contact cutting machine 91 shown in FIGS. 2 to 12 Is applicable, and the non-contact transfer machine 93 of the present invention operates so as to receive the paper 42 at the end of the operation of the non-contact cutting machine 91. In addition, each of the above-mentioned "blower air blowers" has a structure in which a large amount of gas sent from an electric blower or the like is sent through a pipe such as a PVC pipe and supplied from each of the above-mentioned blowout ports. Further, in the specification of this patent, when the term "compressed air nozzle" is used, high-pressure air compressed by a compressor is sent to the nozzle via a vinyl pipe or the like via an air regulator or the like, and this high-pressure air is sent to the nozzle. It means a "compressed air nozzle" that strongly injects air from a plurality of minute spouts having a diameter of about 1 mm.

FIG. 14 is a side view of a novel non-contact carrier 93 used in the non-contact automatic turning system 90 according to a sixth embodiment (Example 6) of the present invention. In FIG. 14, when the paper is raised by the operation of the non-contact carrier 93 of the present invention, a plurality of papers on which necessary contents are printed in advance are bound, and then a designated company name and a store are used as necessary. An example is shown to meet the demand for "name printing" of a calendar that additionally prints names and advertisements on a part of each leaf. In this example, there is a binding margin 17 on one side of the pre-stitched paper, and while the binding margin or the vicinity of the binding margin is pressed by the fixing device 6, the transfer cylinder 9 of the flatbed offset printing machine is predetermined. For printing, the printer enters the range indicated by the print area 81, and additional printing is performed on the top-level paper 40. This print area usually ranges from the edge 18 of the calendar to the inside of about 150 mm. Immediately after printing, the non-contact cutting machine 91 cuts out the printed top-level paper 40. For this non-contact cutting machine 91, the mechanisms described with reference to FIGS. 2a to 12 can be used. Then, in FIG. 14, the non-contact suction chuck machine 60 non-contactly sucks and raises the paper, and the position and shape of the top paper reaches the position and shape indicated by 42, and the non-contact transfer machine 93 of the present invention Receive this form. As explained in paragraph 0029, air 51a is blown diagonally downward from the "blower air blower" 51, reflected by the top paper and the lower paper bundle 2, and the gas 51b flowing upward on the right hand. Here, when the top-level paper moves from the position and shape indicated by 42 to 43, the negative pressure generation region that generates the buoyancy generated by the Bernoulli effect is the gas along the flow of the gas 51b diagonally upward. The edge-side region of the top-level paper formed under the flow of 51b and cut out to the 42 position is generated by the effect of the pseudo-closed space 10 described in paragraph 0029, together with the effect of this negative pressure generation region. It rises further due to buoyancy and moves to the position and shape indicated by 43. As explained in paragraph 0010, a means for combining the physical phenomena of the gas, such as the viscosity of the gas, the frictional force generated between the gas and the paper, and the retention characteristics, is applied to this non-contact carrier, and the paper and the non-contact type are applied. The contact carrier 93 operates so as not to make physical contact with anything other than gas. As described above, the retention characteristic means that the gas is unlikely to flow or move when there is no atmospheric pressure difference between the enclosed space and the external space. As described above, even during the operation of the non-contact transfer machine 93 together with the non-contact cutting machine 91 of the present invention, it is possible to eliminate rubbing of the printed surface immediately after printing, and the period from the cutting operation to the transfer operation is rapid. Since a mechanism that can be controlled so as not to cause deformation of the paper is used, the non-contact transfer machine 93 of the present invention has high quality, can realize stable operation, and can greatly reduce the labor and cost of replacement. A non-contact carrier 93 has been established. In each of the above-mentioned "blower air blowers", for example, a metal or plastic pipe is provided with a slit as a gas blowout port, or a plurality of small holes are provided, and gas from the blower is discharged from the side end of the pipe. It has a gas blower structure to be injected. In addition, the "blower air blower" installed on both sides can use a structure that has a large opening and the air beam does not concentrate. Alternatively, a structure in which the air blown from the electric blower is blown directly or through a pipe can be used. Further, a hybrid structure in which the gas blown out from the electric blower is blown out directly or through a pipe from all or part of the above-mentioned "blower air blowers" and a mechanism for blowing out the compressed gas from another "compressed air nozzle" is used in combination. The method of is also applicable.

FIG. 15 relates to a seventh embodiment (Example 7) of the present invention, and is a non-contact transfer machine 93 for horizontally and forwardly transporting sheet-fed paper by a new non-contact transfer machine 93 used in the non-contact automatic turning system 90. It is a cross-sectional view of. FIG. 15 shows a situation in which one sheet of paper from the bundle of paper 2 before printing uses a known roller, moves by the sheet-fed paper loading mechanism, arrives at the position indicated by 40, and the subsequent printing operation is completed. It is shown. As shown by the arrow 81, the movable printing machine 8 can be installed so that the entire surface on the paper can be moved, and is retracted after the printing is completed. Next, the non-contact cutting machine 91 of the present invention raises one sheet of paper at the position indicated by 40 to the position of 42, and then the paper cutting operation is completed. As the non-contact cutting machine 91, each embodiment of the non-contact cutting machine 91 of the present invention shown in FIGS. 2 to 12 can be applied. The paper at the end of the operation of the non-contact cutting machine 91 is cut off at the position of 42, delivered to the sixth embodiment of the non-contact carrier 93 of the present invention described with reference to FIGS. 13 and 14, and further raised at 43. At the position of the paper indicated, the paper is handed over to the operation of the "blower air blower" of the non-contact carrier 93. Further, the operation of this "blower air blower" will be described. In the seventh embodiment shown in FIG. 15, in the non-contact carrier 93 of the present invention, a plurality of "blower air blowers" 11, 12, and 13 are installed in order to carry the paper at the position 43 in a non-contact manner. is there. The number of installed "blower air blowers" can be 2 to N, but FIG. 15 shows an example of three. Where N is a positive integer. The gas blown out from these "blower air blowers" forms the negative pressure generating regions 21, 22 and 23 generated by the Bernoulli effect, and the friction generating regions 31, 32 and 33 are formed by the viscosity of the gas. Will be done. By the operation of these mechanisms, the paper is further raised from the position of 43 by the buoyancy generated by the negative pressure generation region. Then, when the paper reaches the friction generation region, the paper is conveyed in the direction of the arrow of the dotted line 5 by the frictional force with the gas. As shown in this example, the gas blown out from the "blower air blower" 11, 12, 13 flows in the trajectory shown by the dotted line 5, the paper is conveyed to the position and shape shown by 44, and then "blower air" is shown. It is conveyed further forward by the operation of the blower "12 and 13", falls in front of the stopper 50 on the support base 1, and fits in the position of 49. In addition, since the gas flow is maintained at the upper part of each sheet during the period immediately before the transfer of each sheet of paper is completed, the buoyancy due to the atmospheric pressure difference generated by the Bernoulli effect caused by this gas flow , The sudden drop of each of the single leaves is suppressed. Specifically, on the paper immediately before it fits in the position indicated by 49, the gas blown out from the "blower air blower" flows along the trajectory indicated by the dotted line 5, but gradually flows along the support base. When the paper moves to the position, there is an air flow on the upper surface side of the paper and buoyancy is generated, so that each sheet of sheet does not suddenly fall to the support base. In this embodiment, the case where the negative pressure generation region and the friction generation region are not continuously connected is shown, but if the distance between the adjacent nozzles is set sufficiently shorter than the length of the paper, the paper is conveyed. Since the above-mentioned negative pressure generating effect and friction generating effect sufficiently work on the paper, the same operation as when each negative pressure generating region and the friction generating region are continuously connected is performed. As described above, the non-contact transfer machine 93 that maintains high quality without soiling the paper immediately after printing can be realized by the transfer method using the non-contact transfer machine 93 of the paper of the present invention. In the case of transporting sheet-fed paper, in order to stabilize the paper during transport, the non-contact suction chuck machine 60 replaces the structure in which the chucks are arranged in a straight line as shown in FIG. 12 and the like, and the chucks are arranged in a two-dimensional plane. It may be replaced with the structure.

FIG. 16 is a top view of a non-contact transfer machine 93 for horizontally and forwardly transporting a work by a new non-contact transfer machine used in the non-contact automatic turning system 90 according to a seventh embodiment (Example 7) of the present invention. Is. As shown in FIG. 15, the printing machine 8 may be installed so that it can move on the paper, or it may be installed so that it can print on a part of the paper. The bundle 2 of unprinted paper may be placed at the bottom of the support 1 and the topmost paper may be moved to the 40 position before printing by an appropriate known paper loading device. In the non-contact carrier of the present invention, as described in paragraph 0031, the paper cut out after the printing is completed is further increased by the buoyancy generated by the negative pressure generation region and delivered to the operation of the non-contact carrier 93 of the present invention. The paper is lifted further, and at the position of the paper indicated by 43, the paper is delivered to the operation of the "blower air blower" of the non-contact carrier 93. The paper is conveyed to the position indicated by 44 by the operation of the "blower air blower" 11 or 12, and further, is sent to the front of the stopper 50 on the support base 1 by the operation of the "blower air blower" 12 or 13. While falling, it fits in the 49 position. In the "blower air blower" 11, 12, 13 for example, a metal or plastic pipe is provided with a slit as a gas blowout port, or a plurality of small holes are provided, and gas is injected from the side end of the pipe. It is a "blower air blower". For the injection of this gas, the gas supplied by piping from the electric blower can be used.

FIG. 17 is a novel non-contact transfer machine 93 used in the non-contact automatic turning system 90 according to an eighth embodiment (Example 8) of the present invention, and is a non-contact transfer machine 93 that conveys a work horizontally forward. It is a cross-sectional view of. In this embodiment shown in FIG. 17, after binding a plurality of sheets on which necessary contents are printed in advance, a calendar or the like in which a designated company name, a store name, an advertisement, etc. are additionally printed on a part of each leaf as needed, etc. An example corresponding to the demand for "name printing" is shown. Further, there is a binding margin 17 on one side of the pre-bound paper, and the binding margin or the vicinity of the binding margin is pressed by the fixing device 6 to perform the additional printing. For this additional printing, an industry standard flatbed offset printing machine is used, and in FIG. 17, the transfer cylinder 9 has entered the paper bundle 2 in order to perform the additional printing on the top-level paper. The transfer cylinder 9 of the flatbed offset printing press enters the range indicated by the printing area 81 for predetermined printing, and additionally prints on the top-level paper 40. As described with respect to FIG. 14 in paragraph 0030, this print area usually ranges from the edge 18 of the calendar to the inside of about 150 mm. For this additional printing, for example, an inkjet printing machine can be used. Immediately after the completion of the additional printing, as described with respect to FIG. 15 in paragraph 0031, the paper immediately after the completion of printing is raised to the position of 42 by the operation of the non-contact cutting machine 91 and separated, and is shown in FIGS. 13 and 14. The paper was delivered to the sixth embodiment of the non-contact transfer machine 93 of the present invention described above, further raised, and at the position of the paper indicated by 43, this paper was conveyed by the “blower air blower” of the non-contact transfer machine 93. Handed over to action. In order to convey the sheet immediately after printing, a plurality of "blower air blowers" 11, 12, 13, 14, and 15 are installed in the operation of the non-contact transfer machine 93 in FIG. A plurality of "blower air blowers" can be installed in a plurality of 2 to N units, but FIG. 17 shows an example of 5 units. In the example of FIG. 17, the negative pressure generation regions 21, 22, 23, 24, 25 generated by the Bernoulli effect are formed so as to be continuously connected, and the friction generation regions 31, 32, 33 due to the viscosity of the gas are formed. , 34, 35 are also shown in examples formed so as to be continuously connected. The paper delivered to the eighth embodiment of the non-contact carrier 93 is subsequently formed in the negative pressure regions 21, 22, 23 and the friction regions 31, 32, 33 in which the “blower air blowers” 11, 12, 13 are generated. By function, the paper begins to rise and advance and is guided to the shapes and positions of 44 and 45 in sequence. In the eighth embodiment, the "compressed air nozzle" 13c is installed so as to be used in combination with the "blower air blower" 13, and the compressed gas 13d is used as a pole to support the transport operation of thick, heavy and chewy paper. It is erupting for a short period of time. The paper continues to advance by the functions of the negative pressure regions 24 and 25 and the friction regions 34 and 35 where the "blower air blowers" 14 and 15 are generated, and the paper is guided to the shapes and positions of 46, 47 and 48 in sequence. In this embodiment, the paper finally fits in the position 49 on the shooter 7. In this process, when the paper reaches the friction generating region, the paper is conveyed in the direction of arrow 5 by the frictional force with the gas. In addition, since the gas flow is maintained at the top of each sheet during the period immediately before the transfer of each sheet of paper is completed, the buoyancy due to the atmospheric pressure difference generated by the Bernoulli effect caused by this gas flow , It is possible to suppress the sudden drop of each of the single leaves. Specifically, the paper immediately before it fits in the shooter is located at positions 47 to 48, and the gas blown out from the "blower air blower" 15 descends almost vertically as shown by the dotted line 5 and flows to the shooter. As the paper approaches, it gradually flows along the tilt of the shooter, so when the paper moves from position 47 to position 49, there is an air flow on the back side of the paper that has been turned inside out, and buoyancy is generated. Will not suddenly fall into the shooter or collide. As shown in this example, the gas blown out from the "blower air blower" 11, 12, 13, 14, 15 flows along the locus indicated by the dotted line 5, indicating that an arbitrary transport locus shape can be constructed. .. As described above, in the paper transport mechanism 93 of the present invention, it is possible to realize a non-contact transport machine having high quality that does not stain the paper immediately after printing. In FIG. 17, the negative pressure generation regions 21, 22, 23, 24, and 25 are formed so as to be continuously connected, and the friction generation regions 31, 32, 33, 34, and 35 due to the viscosity of the gas are formed. An example is shown in which the nozzles are formed so as to be continuously connected. However, as described in the example of FIG. 15, even when the nozzles are not continuously connected, the distance between adjacent nozzles is sufficiently shorter than the paper length. Can be operated in the same manner as described above. Further, in FIG. 17, gas is blown from each of the "blower air blowers" mentioned in the description of the side view of the sixth embodiment of the non-contact carrier 93 of the present invention shown in FIG. 14 in paragraph 0030. An example of a method such as a hybrid structure in which a mechanism for blowing compressed gas from another "compressed air nozzle" is used together with a structure for blowing is also shown. Specifically, with respect to the "blower air blower" 51, a hybrid structure with a mechanism for injecting high-pressure air from a plurality of nozzles by using the "compressed air nozzle" 51c in combination is shown as an example. In addition, regarding the "blower air blower" 52 and 53, "compressed air nozzles" 52c and 53c are installed on the left and right and used together, and here again, a hybrid structure with a mechanism that injects high-pressure air from multiple nozzles is used. It is shown as an example. By using this hybrid structure, in the case of thick and hard paper, it is possible to control the air volume and strength of the two types of gas of the hybrid mechanism, or the ejection time, and achieve more stable operation. On the other hand, with thin and light paper, stable operation can be achieved by controlling the ejection time to be short.

FIG. 18 is a top view of a mechanism for horizontally and forwardly transporting a work by a new non-contact transfer machine 93 used in the non-contact automatic turning system 90 according to an eighth embodiment (Example 8) of the present invention. In FIG. 18, in the non-contact transfer machine 93 of the present invention, the top-level paper 40 cut out is cut out from the paper bundle 2 by the non-contact cutting machine 91 of the present invention after printing is completed, and then the non-contact paper 40 of the present invention is cut out. It is delivered to the carrier 93, and is further sequentially conveyed to the position indicated by the dotted line 49 according to the eighth embodiment of the non-contact carrier of the present invention shown in FIG. Similar to the example described in paragraph 0032, the "blower air blower" 11, 12, 13, 14, 15 is provided with slits as gas outlets in various pipes, or is provided with a plurality of small holes on the side of the pipe. It has a nozzle structure in which gas is injected from the end. Further, as described in the above section "0036", the "blower air blower" 51, 52, 53, and 13 are each used in combination with a "compressed air nozzle" to inject high-pressure air from a plurality of nozzles. Although the hybrid structure is shown as an example, the application location of the hybrid structure is not limited to this example. It should be noted that the gas supplied by piping from the electric blower can be used for the injection of this gas by each of the "blower air blowers". Further, the fixture 6 can be configured by a nip mechanism that moves up and down. The function of this non-contact automatic turning system is completed by transporting all pages of the calendar to the shooter, but the calendar with name printing completed leans against this shooter and stops, and then slides down the shooter. Then, it fits in the lower storage box, and the bundle of paper loaded in this storage box and printed with the name is taken out and finished.

We have realized a non-contact automatic turning system that cuts out the paper immediately after printing by the printing press, transfers it to the transfer mechanism, and operates the entire mechanism that transfers the paper in a non-contact manner. It can be applied to all printing applications that need to be rolled up. In particular, it can be mounted on various printing machines as a mechanism capable of preventing the occurrence of stains on the paper immediately after printing. Further, as a work other than paper, it can be applied to a mechanism for non-contactly transporting a high-precision film-like work or a thin plate work. In addition, with regard to calendar name printing, the spread of conventional automatic turning devices has been limited due to a number of restrictions, so even now, many work sites are manually transported and turned by hand. It is used in Japan, and the situation where there is a risk of getting involved in the hands and harsh employment is still continuing, and a system that can overcome this situation has been realized, so it is also possible to improve the harsh working environment. Can be useful. Further, the cutting mechanism and the transport mechanism of the automatic turning system of the present invention can be used to print each page of a book whose one side is bound when digitizing "bound books", old books, documents, etc., whose demand has been increasing in recent years. It can also be applied to the rolling mechanism of each sheet of paper when it is rolled and electronically copied by a scanner. It can also be applied to the stable operation of high-speed page turning on thin and soft paper.
