Description

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

Demand for printing on the next sheet immediately after printing on one sheet cut out from a bundle of sheets, and each sheet bound after binding multiple sheets pre-printed with necessary content Of these, there is a demand for additional printing of a specified company name, store name, advertisement, etc., as necessary, in a part of each predetermined sheet, and the next sheet immediately after printing on one sheet In order to enable printing on the leaf, it is necessary to have a technique for immediately cutting out and moving each leaf immediately after printing. In addition, the present invention relates to a “paper non-contact automatic turning system” using a new technology that does not physically contact a substance other than gas and the entire printing surface so as not to contaminate the printing surface. It is.

Conventionally, in order to move immediately after printing on one sheet cut out from a bundle of sheets, a technique of cutting, turning or moving using a roller has been used. When a roller is used, the entire surface of the paper is pressed by the roller and cut out, turned, and further conveyed while being rotated. Therefore, the printing portion of each leaf may be rubbed while the ink is not dry. Therefore, a technique for emergency drying has been developed before rubbing the paper immediately after printing, and examples thereof are techniques for instantaneous drying and coating by making full use of UV printing, pre-coating and post-coating techniques. However, these technologies can be expensive, such as the need to use expensive ink in addition to the initial cost, and complicated and expensive mechanisms are required, limiting their use to limited use. . The present invention provides a paper cutting technique immediately after printing, and a technique for transporting this paper, in order to prevent ink rubbing, which is useful for applications where the above-mentioned instantaneous drying technique is expensive and complicated and cannot be used. The present invention relates to a new technology in which the operation of all the mounted mechanisms does not rub the entire printing surface of each sheet and does not rub the paper immediately after printing on which ink has just been placed.

Further, in recent years, ink has been improved and the paper immediately after printing is not directly rubbed. Further, as long as the paper immediately after printing is stacked so as not to apply a physical impact to the paper, the printing surface is stained or so-called. The problem of show-through does not occur. Therefore, technology for stacking sheets at the end of conveyance with an operation without physical shock is important, and it relates to a non-contact automatic rolling system that has taken such measures.

Actual Application Sho 63-28383 Japanese Patent Application No. 61-260954 Japanese Patent Application No. 2015-011822

Practical use of a mechanism that uses a roller as a means to separate the first sheet from the second and subsequent sheets when cutting out a sheet just after additional printing from a booklet or calendar in which one side of the sheet is bound to some areas. Has been. In the passbook page turning mechanism disclosed in Utility Model Document 1, a roller is used for cutting and turning the paper immediately after printing. In addition to this example, many commercially available printers use a plurality of rollers for separation, movement, and conveyance for cutting out paper before and after printing. When a roller is used, the surface of the paper is rubbed during rotation, so rubbing this print area immediately after printing will cause ink stains and reduce print quality. For booklet and calendar printing where precise print quality is required Even if it is necessary to install a roller so that the printed part immediately after printing is not rubbed, or even when additional printing is performed only in a part of the area, `` Install the roller only in a place that does not rub this printed part. In some cases, there was a large restriction such as “allowing”. In addition, the rollers are generally “periodic replacement parts”, and for these rollers that are also used in business printers, information on “periodic replacement parts” is provided to users from printer companies. According to these information, regarding various rollers, it is described that the number of prints of about 200,000 sheets of paper such as A4 size plain paper or high-quality paper is the replacement life. The first problem to be solved is to realize a method that can avoid the restrictions imposed when rollers are used, especially in the case of "name printing" on a calendar, paper that is twice or four times larger than 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 the deterioration of the quality of the printed part additionally printed and to greatly reduce the labor and cost of replacement, instead of the roller technology. It is to realize a non-contact automatic turning system capable of cutting out and carrying operation without using a roller for the cutting mechanism, turning and carrying mechanism.

Patent Document 1 discloses an embodiment in which the first sheet is separated from the second and subsequent sheets by a vacuum suction nozzle. In this embodiment, since a part of the paper to be cut out is sucked by the vacuum suction nozzle, if the area immediately after printing is sucked, the printing portion is rubbed and stains are generated. was there. The second problem to be solved is to establish a non-contact automatic turning system capable of cutting out, turning and transporting paper without any restrictions when using suction nozzles. It is possible to print to the edge or the edge of the edge of the edge. Moreover, in this patent document 1, after the paper printed by the vacuum suction nozzle is adsorbed and separated from the second and subsequent sheets, the gas blown from the “compressed air nozzle” is struck against the back surface of the paper, and the paper is blown off. A moving embodiment is disclosed. In this embodiment, soft and light paper frequently causes wrinkles on the paper, resulting in a reduction in the quality of the printed matter. Also, it was difficult to blow off paper with thick, heavy and firm 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 blown air against the back side of the paper and blows it away in order to avoid degradation of the quality of the paper being conveyed. Thus, a non-contact automatic paper turning system is established.

Conventionally, in order to prevent deterioration in print quality even when rubbing immediately after printing, development of technology for instantaneous drying using UV printing or pre-coating technology has been performed. In order to use these techniques, an expensive apparatus is required, special ink is required, and the temperature around the apparatus becomes high. Similarly to the ink nozzle that ejects printing ink, a pre-coating agent application nozzle is installed, and the pre-coating agent is ejected immediately before the spot where the ink is ejected to absorb the ink immediately and suppress bleeding. It has become. This mechanism uses a control mechanism that maintains the same definition as the ink head, and sprays the pre-coating agent just before every ink dot for every dot on which the ink is placed. There was a problem that the control mechanism required precision. The fourth problem to be solved by the present invention is that, as an alternative to an expensive and complicated technique of instantaneous drying using UV printing or pre-coating technology, a mechanism such as paper cutting, turning, and conveyance is not contacted. Is to establish a non-contact automatic page turning system for paper. In recent years, ink has been improved, and even cheap inks that can be used normally are rubbed directly on the printing surface of the paper immediately after printing, and the paper is stacked so as not to apply physical shock to the paper immediately after printing. As long as the print surface is not smudged or a so-called show-through problem does not occur. In the present invention, the above-mentioned instantaneous drying technique is expensive and complicated, so that it can be used in an application field that cannot be used. In order to prevent ink rubbing that is useful in conjunction with improved ink technology, the paper is cut out immediately after printing. The mechanism and the operation of all mechanisms of the paper transport mechanism do not rub the entire printing surface of each sheet, thus establishing a new technology that does not rub the paper immediately after printing on which the ink has just been placed. The printed area and all of the above mechanisms operate in a non-contact manner, and the paper at the end of transportation is operated without physical shock. It is to realize a non-contact automatic punching system that can be stacked on top of each other.

Japanese Patent Application No. 2015-011822 discloses a “paper turning device for turning paper contained in a booklet”, and an attached portion to which the turning paper to be turned is attached. Displaced so that it moves toward the inside of the periphery and the attached part moves away from the booklet, or in a direction away from the edge of the booklet when the turning paper to be turned is attached A gap forming member that rotates and forms a gap between the turning sheet and another sheet included in the booklet, and a member other than the gap forming member is used after the gap is formed by the gap forming member. And a paper turning device comprising means for turning the turning paper. Means using an adhesive tape or air suction is disclosed as means for forming the adhered portion. A fifth problem to be solved by the present invention is to turn the turning paper using a member other than the gap forming member after the gap is formed by the gap forming member that forms a gap and the gap forming member. It is to establish a non-contact automatic punching system that can suppress an increase in cost due to the need for separate means. In addition, the Japanese Patent Application No. 2015-011822 uses a gap forming member such as a negative pressure by suction of an adhesive tape or air as means for cutting out the sheet, and the gap forming member is directly connected to the sheet to be cut out. A contacting embodiment is disclosed. The sixth problem to be solved by the present invention is to establish a non-contact cutting-out technical means that can make a gap without causing the paper to be cut out and the gap forming member to contact with anything other than gas. As described above, since the conventional automatic turning apparatus has a number of restrictions, its spread has been limited. For this reason, even today, manual conveyance and turning work by hand are used in many work sites. In particular, the calendar sheet is transported and turned by hand using a flat-table offset printing machine, and there is still a risk of getting involved in the hands and the situation where severe work is forced. It is a big problem to be solved.

As described above, the present invention relates to the first problem related to the use of rollers, the second problem related to the use of suction nozzles, the fourth problem related to the use of expensive high-speed drying technology, and In order to solve the sixth problem related to the direct contact between the sheet to be cut out and the gap forming member, the buoyancy due to the pressure difference generated by the Bernoulli effect caused by the flow of gas is used, the viscosity of the gas Applying the means to combine the physical phenomena of gas, such as the frictional force generated between gas and paper and the gas retention characteristics, and the pseudo-splitting effect of the space created by the flow of gas, that is, the air curtain effect, to the paper turning system However, a non-contact automatic turning system is constructed in which the printing surface of the paper is in contact with only the gas and all the mechanisms of the turning system are not in direct contact with the paper. To solve the problems. Note that the retention characteristic means that the gas does not easily flow or move when there is no pressure difference between the enclosed space and the external space. Paper balloons are an example. In addition, the suction chuck used for the cutting or gap making operation performed in the first half of the automatic page turning system also uses the non-contact suction chuck that uses the Bernoulli effect, so that the non-contact operation is maintained in the cutting operation, and the paper suction location Even when the paper moves with the movement of the paper, the problem is that the paper slides without physical contact with all the mechanism members including the suction chuck due to the gas existing between the paper and the suction pad. ing. Next, means for solving the third problem will be described. Conventionally, high-pressure gas compressed by an air compressor is guided to a “compressed air nozzle” by vinyl piping via an air regulator, etc., and blown out from this “compressed air nozzle” having a plurality of minute outlets having a diameter of about 1 mm. High pressure gas characterized by concentration and strength is used, but instead of this conventional technology or in combination with this conventional example, the gas sent from the electric blower that makes use of the feature that the air volume becomes large is used as a PVC pipe etc. The pressure is low and the force is low, but it is generated by the flow of gas using a "blow air blower" that has a structure that blows out gas uniformly from a large number of large air outlets or one very large air outlet. Using the buoyancy due to the pressure difference generated by the Bernoulli effect and the viscosity of the gas or between the gas and the paper Is used Use technology frictional force as means for solving the problems that. Further, in the period immediately before the completion of the conveyance of each sheet of paper, the above-mentioned “blowing air blower” that maintains the flow of gas is installed on the upper side or the side surface of each sheet, thereby generating this gas flow. The characteristic that suppresses the sudden fall of the individual sheets due to the buoyancy caused by the pressure difference generated by the Bernoulli effect is used as the problem solving means. Further, a method of maintaining a non-contact operation not only on the printing surface but also on the back surface side is used as one of the problem solving means. Further, as a fifth problem solving means, an example in which a conventional rotating member is formed by winding an adhesive tape is shown, and an embodiment in which an adhesive is exposed on the outer peripheral surface is disclosed. As another example, means for vacuum suction is illustrated. In the present invention, by using a non-contact suction chuck that utilizes the Bernoulli effect instead of this adhesive or vacuum suction, a technique for sharing this non-contact suction chuck even during the operation of the general non-contact cutting machine is used as a problem solving means. ing. Further supplementally, most of the high-pressure air ejected from the plurality of non-contact adsorption chucks, “compressed air nozzles” and the gas blown out from the “air blowing air blower” blows on the printing surface of each sheet immediately after printing. Since the operation is performed so as to flow, a technique for exhibiting an auxiliary effect of ink drying immediately after printing is also used as an auxiliary means for solving the fourth problem related to ink drying.

As described above, the non-contact automatic page turning system of the present invention can be applied to application fields such as booklet printing and calendar name printing, which are examples of fields in which emergency drying of ink is difficult. Immediately after printing the name on the calendar, the name is printed on the next page, so it is necessary to move the paper immediately. With the non-contact automatic page turning system of the present invention, the printing section that has been additionally printed without directly rubbing the print surface immediately after printing and without using a mechanism such as UV drying or pre-coating that requires expensive equipment and operation costs It is possible to avoid degradation of the quality of the product and to reduce the labor and cost of replacement. In addition, the conventional automatic turning system is not widely used due to the restrictions described in paragraphs 0006, 0007, and 0008, and the industry as a whole is delayed in automation, and is still in the workplace where hand-working is still performed. The realization of the non-contact automatic turning system of the present invention that can eliminate the limitations of the conventional automatic turning system can bring about an effect that it can contribute to the elimination of a severe work site. Furthermore, in the manual work that is still performed in many name printings, the paper is grasped with one hand, cut out, turned, moved, and the next calendar is carried in with the other hand. At that time, it was difficult to maintain uniformity in the movement of the paper, and the paper sometimes wrinkled. For this reason, a notice on the calendar on the homepage of the National Federation of Fans and Fans Calendar Council contains a notice that “wrinkles (paper folds) are attached to humans so that they can be turned by hand”. On the other hand, the non-contact automatic drilling system of the present invention does not rely only on high-pressure gas ejection or vacuum technology characterized by concentration and strength, but the gas sent from the electric blower that makes use of the feature that increases the air volume is piping such as PVC pipe The air pressure is low and the force is weak, but a large number of large air outlets and a “air blowing air blower” with a structure that blows out gas uniformly from one very large air outlet are also used, providing a good balance in the horizontal direction of the paper. Since a cutting operation, a transport operation, and the like are performed, it is also a great effect that wrinkles can be avoided even in thin paper that is easily wrinkled, unlike in manual operations. According to the present invention, it is an example of a field where it is difficult to urgently dry ink, and after assembling and binding a plurality of sheets preprinted with necessary contents as described above, a designated company name and store name are specified as necessary. In response to the demand for “name printing” such as a calendar that prints additional information on a part of each leaf later, and when moving a sheet immediately after this additional printing, there is no deterioration in the print quality of the paper. Therefore, it is possible to provide a transport mechanism at a low cost without selecting the type of paper, such as thick or thin. In addition, as a work other than the paper, a mechanism that can be applied to non-contact cutting of a film-like work or a thin work can be provided. Also, expensive equipment and operation costs are required when cutting out a printed sheet immediately after printing on all areas of the sheet one by one on a plurality of sheets and printing on the next sheet continuously. It is possible to provide a mechanism that prevents ink show-through without using a mechanism such as UV drying or pre-coating. Furthermore, the printing press used with the present invention performs master operation for timing control, and the non-contact automatic page turning system of the present invention operates as a slave. It can be said that the internal operation of this non-contact automatic turning system that operates as a slave within an allowable range determined by the operation timing of the printing press can be finely adjusted by a computer control mechanism.

Except for the fixing mechanism that holds down the binding margin of the paper or the vicinity of the mechanism of the booklet and calendar paper cutting mechanism immediately after printing and the paper transport mechanism when cutting is completed, substances other than gas are A non-contact automatic page turning system using new means that enables non-contact operation without directly rubbing the entire print surface, and also allows the use of a method that maintains non-contact operation not only on the print surface but also on the back side. It was realized. Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a configuration diagram showing an entire non-contact automatic turning system 90 according to a first embodiment (embodiment 1) of the present invention. This non-contact automatic page turning system 90 is composed of a non-contact cutting machine 91 and a non-contact transfer machine 93 for transferring the cut-out completed paper as indicated by an arrow 97 after completion of the cutting operation. Each sheet at the time of completion is configured to have a transport mechanism portion that can be stacked on a sheet that has already been transported by an operation without physical shock. Further, a computer control mechanism 98 is installed in this non-contact automatic turning system, and the non-contact cutting machine 91 and all the mechanisms of the non-contact transfer machine 93 are systematically 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 the second embodiment (embodiment 2) of the present invention. In FIG. 2a, the four large arrows positioned up, down, left, and right indicate the direction of the paper. A vertical arrow 36 on the left side indicates the front side, and an arrow 37 on the right side indicates the rear side. Further, the horizontal arrow 38 on the lower side indicates the right side, and the arrow 39 on the upper side indicates the left side. A binding margin 17 bound with metal fittings or cardboard is provided on the top side of the top of the top sheet 40, and this top side is the rear side. On the other hand, the ground side 18 is called a forehead in the calendar, and this side is the front side. A non-contact suction chuck machine 60 is installed at the center. The upper side of the non-contact suction chuck machine 60 is the left side 39 and the lower side is the right side 38.

Next, FIG. 2b is a sectional view (1) as seen from the front side of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the second embodiment (embodiment 2) of the present invention. In FIG. 2b, the non-contact suction chuck machine 60 is in the upper standby position (first height). The non-contact suction chuck device 60 is moved up and down by a left air cylinder 56 installed on the left side and a right air cylinder 57 installed on the right side. This up-and-down movement can be performed by a mechanism in which a single air cylinder is installed at the center, or a motor can be used as power. A bundle of sheets having a binding margin is placed on the support base 1, and the uppermost sheet 40 of the bundle is displayed separately. Further, in order to prevent double feeding of sheets when cutting out sheets, sheet pressers 54 and 55 for pressing the remaining stack of sheets after cutting out the uppermost sheet are installed on the left and right sides. From this state, the non-contact suction chuck machine 60 descends as the air cylinder descends. At this time, gas is blown out from the “compressed air nozzle (left)” 65 installed on the left side and the “compressed air nozzle (right)” 66 installed on the right side, and the gas is blown between the uppermost sheet of the bundle of sheets and other sheets remaining in the lower part. Can be provided to release the pressure-bonding between the sheets and assist the non-contact suction operation of the non-contact suction chuck device 60 for the uppermost sheet. In the specification of this patent, when it is expressed as “compressed air nozzle”, as described above, the high-pressure air compressed by the compressor is sent to the nozzle through the air regulator or the like through the vinyl pipe, etc. It means a “compressed air nozzle” that strongly injects high-pressure air from a plurality of minute nozzles having a diameter of about 1 mm.

FIG. 3 is a sectional view (2) as seen from the front side of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the second embodiment (embodiment 2) of the present invention. In FIG. 3, the non-contact suction chuck machine 60 is in a position where the lowering is completed, and enters a non-contact suction operation. The lowering completion position of the non-contact chucking machine 60 is set to a position (second height) at which the negative pressure generation region 59 by the non-contact chuck reaches the uppermost sheet 40. FIG. 3 shows a point in time when the non-contact suction chuck device 60 has reached the second height at which the negative pressure region 59 is in contact with the uppermost sheet 40.

FIG. 4 is a sectional view (3) seen from the front side of a novel non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the second embodiment (embodiment 2) of the present invention. In FIG. 4, the non-contact suction chuck machine 60 is stopped at the second height, but the uppermost sheet is lowered by the buoyancy due to the pressure difference generated by the Bernoulli effect caused by the gas flow. A position drawn to the chuck machine 60 and raised to a position indicated by 41 is shown. At this time, the negative pressure generated by the Bernoulli effect is blocked by the adsorbed uppermost sheet, does not act on the sheet underneath, and does not cause a double feed. Thereafter, the uppermost sheet is further raised from the position 41 by the raising operation of the left and right air cylinders to complete the cutting operation. At this time, in order to avoid the double feeding of the lower sheet due to the negative pressure generated between the sheet remaining in the lower part due to the sudden rise of the uppermost sheet, the left sheet presser (left) 54 The right sheet presser (right) 55 is operated to press the sheet bundle 2 remaining in the lower part. In order to prevent further multi-feeding at this time, operation such as jetting of gas that functions as an air brush is performed on the paper remaining in the lower part, or “compression” installed on the left and right for high-speed suction of the gas remaining between the lower papers “Air nozzles” 65 and 66 may be operated. In the case of this high-speed suction, high-speed suction of gas can be performed by piping through a device called an ejector. The left paper presser (left) 54 and the right paper presser (right) 55 operate to press the paper bundle 2 remaining in the lower portion. However, this paper bundle 2 is an unprinted paper and causes print stains. Does not matter. Further, since the left and right sheet pressers sink without contacting the lower side of the uppermost sheet immediately after printing, the print quality of the sheet immediately after printing is not deteriorated. By such an operation, the uppermost sheet and the sheet bundle remaining in the lower part are separated at the third height. Further, the left and right sheet pressers may be kept in the operation of only entering without contacting the lower side of the uppermost sheet immediately after printing without performing the operation of pressing down the unprinted sheet downward.

FIG. 5 is a sectional view (4) seen from the front side of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the second embodiment (embodiment 2) of the present invention. In FIG. 5, the non-contact suction chuck unit 60 is lifted in a state in which the uppermost sheet is sucked in a non-contact manner by the raising operation of the left and right air cylinders, and the uppermost sheet reaches the position (fourth height) indicated by 42. In addition, you may return to the original 1st height instead of this 4th height. In addition, since the non-contact suction chuck that uses the Bernoulli effect is used as the suction chuck for cutting, even when the top non-contact suction position of the top paper rises to the position 42, the top paper also moves in the vertical direction. Due to the gas present between the paper and the suction pad, the paper operates so as to take advantage of the property of sliding without making physical contact with anything other than the gas. This misaligned paper behavior always occurs when the paper is bundled due to the binding margin, so mechanical gripping mechanism or vacuum suction causes tension with the binding margin of the paper and damages the paper. May give. When the above cut-out operation is completed, the non-contact chuck suction operation of the uppermost sheet at the position indicated by 42 stops, and is separated from the non-contact cut-out machine 91, and as shown in FIG. The state immediately before being delivered to is shown. Note that during the operation of the cutting mechanism 91, the paper to be cut operates not only from the front side of the paper but also from the back side without physical contact with the non-contact cutting function from the start to the end of the cutting.

FIG. 6 is a sectional view (1) seen from the front side of a novel non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the third embodiment (Example 3) of the present invention. In the third embodiment shown in FIG. 6, a center / air cylinder 58 is added to the second embodiment shown in FIG. The purpose of this is to move the air cylinders 56 and 57, which move up and down at once, by a small width and move the non-contact suction chuck machine 60 up and down by a small amount. In this sectional view (1), the left and right air cylinders 56 and 57 are at the uppermost position, the center / cylinder 58 is also at the uppermost position, and the non-contact suction chuck machine 60 is also on standby at the uppermost position (first height). When the lowering starts next, both the left and right air cylinders and the center / air cylinder move to the lowest positions in the cylinder operating range.

FIG. 7 is a sectional view (2) seen from the front side of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the third embodiment (third embodiment) of the present invention. In FIG. 7, the left and right air cylinders 56 and 57 and the center / air cylinder 58 are both moved to the lowest position. Also here, the lowering completion position of the non-contact chucking machine 60 is set to a position (second height) where the negative pressure generation region 59 by the non-contact chuck reaches the uppermost sheet 40. The non-contact suction chuck machine 60 reaches the lowest position, starts non-contact suction, and the top sheet is sucked at the position indicated by 40 by the buoyancy due to the pressure difference generated by the Bernoulli effect generated by causing the gas flow. The started state is shown.

FIG. 8 is a cross-sectional view (3) seen from the front side of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the third embodiment (third embodiment) of the present invention. In FIG. 7, the non-contact suction chuck machine 60 reaches the lowest position and starts non-contact suction and starts to rise. In FIG. It rises to a height of 3. This ascending position is set to an ascending position at which a sufficient clearance can be secured for the sheet pressers 54 and 55 installed on the left and right to enter between the uppermost sheet at the position 41 and the sheet bundle 2. Similar to the explanation of the operation in FIG. 3 in the paragraph 0017 and the explanation of the operation in FIG. 4 in the paragraph 0018, in order to prevent double feeding before and after the suction start, an operation such as gas injection that functions as an airbrush is performed on the sheet remaining below. 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 can be performed by piping through a device called an ejector. The right and left air cylinders 56 and 57 move to the uppermost position immediately after the entry operation of the sheet pressers 54 and 55 into the gap is completed. It is also possible for the sheet pressers 54 and 55 installed on the left and right to enter between the uppermost sheet and the sheet bundle 2 during the period in which the center / air cylinder is ascending to the third height. is there. In this case, it is possible to start the raising operation of the left and right air cylinders 56 and 57 at the final stage in which the center / air cylinder rises to the third height. Similar to the description of FIG. 8 in the paragraph 0018, this operation separates the uppermost sheet and the sheet bundle remaining in the lower part at the third height, and the non-contact suction chuck machine stops at the third height. Alternatively, it is possible to set this separation while passing through the third height.

FIG. 9 is a cross-sectional view (4) seen from the front side of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the third embodiment (third embodiment) of the present invention. In FIG. 9, the left and right air cylinders 56 and 57 move to the uppermost position, and the non-contact suction chuck device 60 also returns to the uppermost position (first height), and the uppermost sheet reaches the position indicated by 42. To do. As in the second embodiment of FIG. 5, the suction chuck used at the time of cutting is a non-contact suction chuck that uses the Bernoulli effect. Therefore, when the non-contact suction position of the top paper rises to the position 42, the top paper Even when the sheet moves in the vertical direction, the sheet operates by taking advantage of the characteristic that the sheet slides without physically contacting with the gas other than the gas by the gas existing between the sheet and the suction pad. This misaligned paper behavior always occurs when the paper is bundled due to the binding margin, and mechanical gripping mechanism or vacuum suction causes tension with the binding margin of the paper and damages the paper. May give. When the cutting operation is completed and the uppermost sheet at the position 42 is stopped, the non-contact chuck stops and is separated from the non-contact cutting machine 91, and as shown in FIG. The state just before delivery is shown. As in the second embodiment of FIG. 5, during the operation of the cutting mechanism 91 of the third embodiment, the paper to be cut out is not only the front side but also the back side of the paper from the start to the end of the cutting. Works without touching.

FIG. 10a is a sectional view (2) as seen from the front side of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the fourth embodiment (embodiment 4) of the present invention. In contrast to the sectional view (2) of the second embodiment of the non-contact cutting machine 91 of the present invention of FIG. 3 and the sectional view (2) of the third embodiment of the non-contact cutting machine 91 of the present invention of FIG. As shown in the figure, a left end non-contact suction chuck 69b and a right end non-contact suction chuck 69c, each of which can tilt the non-contact suction surface outward, are attached to both ends of the non-contact suction chuck machine 60, respectively. 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 is a cross-sectional view (2) of the second embodiment of the non-contact cutting machine 91 of the present invention shown in FIG. Similarly 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) at which the negative pressure generation region 59 by the non-contact chuck reaches the uppermost sheet 40. Set to.

FIG. 10B is a sectional view (3) seen from the front side of a novel non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the fourth embodiment (Embodiment 4) of the present invention. In FIG. 10b, the non-contact chucks 69 and 69c added to the both ends are inclined only at the time of an operation of opening a larger gap by means described later with reference to FIG. At this time, due to the change in the structure of the non-contact suction chuck device 60, the negative pressure region is generated at the position 59 as in the example of FIG. 3 or FIG. 2 negative pressure regions 59b and 59c are generated, and the non-contact suction operation raises the uppermost sheet slightly from the position 40 shown in FIG. 10a. Due to the generation of the second negative pressure regions 59b and 59c, both end portions of the uppermost sheet at the position 40 are bent upward, and more gaps are left. Thereafter, when the installation angles of the non-contact chucks 69b and 69c are returned by the means described in the paragraph 0027 and all the bottom surfaces return to the second height position, the uppermost sheet is returned to the original position by the non-contact suction of the non-contact chuck. The horizontal state is reached at a position slightly higher than the 40 position. Although depending on the properties of the paper, there is a paper waist that suppresses bending due to fiber and the like. The uppermost paper is superior to the stiffness of the paper and bends according to the shape of the negative pressure area due to non-contact suction of the non-contact chuck, but the paper in the lower paper bundle is between the paper waist and the paper in close contact The sheet is not bent by the negative pressure and remains at the position of the sheet bundle 2. In addition to the fact that the influence of the negative pressure region generated between the chuck and the uppermost sheet by the Bernoulli chuck on the lower sheet bundle is blocked by the uppermost sheet itself, the non-contact suction chuck is a Bernoulli type The vacuum penetration does not occur through the fine fiber holes of the uppermost sheet unlike the vacuum chuck, and it is not attracted to the uppermost sheet and lifted. To summarize the above, in the non-contact cutting machine, when the gap between the uppermost sheet and the sheet immediately below the gap occurs due to the strength of the uppermost sheet due to the stiffness of the uppermost sheet, it remains between the sheets. Operates under the condition that the non-contact-adsorbed uppermost sheet rises or bends to increase the gap between the lower sheet and the sum of the forces that keep the sheets 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 sheet is bent, there is a gas blown from the chuck between the non-contact suction chuck and the top sheet, and it operates like an air mat, so there is no crease. . 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 sheet pressers 54 and 55 can be easily inserted between the uppermost sheet and the lower sheet bundle that are opened larger.

FIG. 10c is a sectional view (4) seen from the front side of a novel non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the fourth embodiment (embodiment 4) of the present invention. Here, only the center / air cylinder 58 rises, the non-contact suction chuck machine reaches the third height, and the uppermost sheet rises to a position indicated by 41. In addition, after the non-contact chucks 69 and 69c added to both ends are rotated and tilted so as to open a larger gap, they may be reversely rotated back during the period described with reference to FIG. 10b. When the center / air cylinder 58 is raised, it can be reversely rotated back. In FIG. 10c, means for explaining the non-contact chuck added at both ends in parallel during the period when only the center / air cylinder 58 rises and the non-contact suction chuck machine reaches the third height is described in the next paragraph 0027. Thus, the rotation is reversed, the bottom surfaces of all the non-contact chucks are leveled, and the center / air cylinder 58 is lifted by the amount raised to reach the third height. Since the position of the uppermost sheet moves to a height indicated by 41, the sheet pressers 54 and 55 installed on the left and right sides have non-contact chucks 69b and 69c added to both ends in the period described in the paragraph 0025. The sheet presser can be inserted during the period shown in FIG. After the operation of inserting the sheet pressers 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 uppermost position at the fourth height. Or you may return to the original 1st height directly. Note that, as described in paragraph 0018, during this period, the presser presses the unprinted lower sheet, but operates so as not to contact the uppermost sheet immediately after printing.

FIG. 11 is a cross-sectional view (3) seen from the front side of a new non-contact cutting machine 91 used in the non-contact automatic turning system 90 according to the fifth embodiment (Embodiment 5) of the present invention. The operation and mechanism for rotating and tilting the non-contact chucks 69b and 69c installed at both ends in FIGS. 10b and 10c and for returning them to the original will be described with reference to FIG. There is a mounting base 76 for the non-contact chuck 74 having a virtual fulcrum 72 on the left side and a mounting base 77 for a non-contact chuck 75 having a virtual fulcrum 73 on the right side. The non-contact chucks 74 and 75 rotate along three concentric circular 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 performs rotational movement using the power of an actuator or the like, using two long holes formed in the mounting bases 76 and 77 along the arc. As a result of this operation, buoyancy due to the pressure difference generated by the Bernoulli effect is generated at the positions 59b and 59c, and both ends of the uppermost sheet 40 are rolled up to generate a gap. Even when the left and right non-contact chucks that rotate along the arcs centered on the left virtual fulcrum 72 and the right virtual fulcrum 73 are operated by such a method, a larger gap is formed. The non-contact operation can be maintained over the entire printing surface of the paper. The non-contact chuck can be returned to the horizontal state before the rotation by rotating the non-contact chuck around the virtual fulcrums 72 and 73 using the power of the actuator. Further, as described in the operation of FIG. 10c in the 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 uppermost 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 the fifth embodiment (embodiment 5) of the present invention. Similar to FIG. 2a described in the paragraph 0015, in this figure, four large arrows indicate the direction of the paper. A vertical arrow 36 on the left side indicates the front side, and an arrow 37 on the right side indicates the rear side. Further, the horizontal arrow 38 on the lower side indicates the right side, and the arrow 39 on the upper side indicates the left side. FIG. 5 of the embodiment of Japanese Patent Application No. 2015-011822 described in the paragraph 0009 shows a view in which the adhesive tape attached to the rotating member is installed on the left and right side surfaces. 9A and 10A of the embodiment of the Japanese Patent Application No. 2015-011822, suction machines using suction air are installed on the left and right side surfaces of the calendar paper. In these conventional means, a tension is easily generated between the binding margin of the sheet and an adsorber using an adhesive tape or suction air, and a defect such as a wrinkle may occur on the sheet. On the other hand, Examples 2 to 4 shown in FIGS. 2 to 10c of the present invention disclose examples which do not cause such a problem. Furthermore, the fifth embodiment of the present invention shows technical means for realizing the non-contact cut-out operation by an installation method that does not cause ink stain immediately after printing and does not cause deterioration of paper quality such as paper wrinkles. This will be described 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 the top view. . A line segment 84 is a line segment having an intercept on the side connecting 82A and 82D of the right triangle having the three points 82A, 82D, and 82E and the side connecting 82A and 82E. Similarly, the right virtual fulcrum 73 is installed next to the non-contact chuck 75 additionally installed on the right side surface 38 side. In actuality, as shown in the top view, the right fulcrum 73 is installed at an angle of an oblique line segment 85. is there. A 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 whose apexes are three points 82B, 82C, and 82E. This is because the line segments 84 and 85 intersect on the calendar, or each intersect with the binding margin 17 and the fixing device 6 so that no abnormality such as wrinkles occurs on the topmost sheet of the calendar. In addition, the length of the fixing device is usually set shorter than the binding margin, but when it becomes longer, the apex 82D or 82C of the triangle may be at both ends of the fixing device, respectively. Along with this, the vertices 82A and 82B, which are right angles of the right triangle, respectively move from the both ends of the fixing device 6 to the intersections where the perpendiculars drawn to the small edge 18 of the calendar intersect the small edge. In summary, the non-contact chucks on both the left and right sides that rotate around the two virtual left and right fulcrums are installed in the region of the uppermost sheet to be sucked when viewed from above, and the above-mentioned when viewed from above. Two extension lines of the left and right virtual fulcrums do not intersect on the uppermost sheet, and an extension line viewed from above the two virtual left and right fulcrums further extends on the uppermost sheet. The condition for not causing wrinkles on the paper immediately after printing is that it does not intersect the binding margin portion or the paper fixing portion by the fixing device that presses the uppermost paper from above. Further, eliminating the collision between the crease and the crease and eliminating the collision between the crease and the fixing device or the binding margin is a condition that does not hinder the operation of forming the gap, and is a condition for preventing the generation of wrinkles. Since the non-contact chucks 74 and 75 added to the left and right side surfaces are installed on the calendar paper, a stable non-contact suction operation is possible, so that the line segments 84 and 85 intersect with the sides. 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. In addition, the left and right virtual fulcrums 72 and 73 perform the same operation even when they are actual fulcrums. When the fulcrum can be installed at a position away from the area immediately after printing, even if the paper immediately after printing and the actual fulcrum are in physical contact with each other, the actual printing point will not be rubbed. A fulcrum can also be set up. Furthermore, in the description from FIG. 2 to FIG. 10 c, the “compressed air nozzle” from the left and right sides is performed once or a plurality of times during the period from immediately before to immediately after the gap-opening operation of these Examples 2, 3, and 4. Then, air can be jetted into the gap portion to perform a treatment for releasing the pressure-bonded state between the sheets due to static electricity or moisture.

FIG. 13 is a top view of a new non-contact transfer machine 93 used in the non-contact automatic page turning system 90 according to the sixth embodiment (embodiment 6) of the present invention. Example 6 of this non-contact transporter 93 is a non-contact suction chuck device 60, a sheet bundle 2 having a binding margin 17, a fixing device 6, and a “blower air blower installed on the front side, left side and right side” ”51, 52 and 53, and the pseudo enclosed space 10. As shown in FIG. 13, when the top surface of the sixth embodiment of the non-contact transporter 93 is looked down on, the non-contact suction chuck device 60 of the non-contact clipping machine 91 rises to the uppermost position on the support base 1, You can see the topmost paper raised to the position. Since the rear side is held down by the fixing machine 6 due to this ascent, the front edge 18 of the sheet moves in the direction of the rear side 37 by the movement to the position 42, and the rear side is the lower side. A part of the edge side of the sheet bundle 2 can be seen. The configuration and operation of the pseudo enclosed space 10 are as follows. First, there is a binding margin 17 for binding the sheet bundle on the rear side, and a fixing device 6 for holding the sheet bundle 2 and the uppermost sheet of the sheet bundle from above. In addition, a front-side “air blower” 51 is installed above the support base and is provided with a plurality of slits and a plurality of air outlets, and gas is blown obliquely downward toward the support base 1 as indicated by arrows. The The arrows connected in series indicate the gas flow incident on the uppermost sheet or the lower sheet bundle 2 and the gas flow reflected on the uppermost sheet or the lower sheet bundle 2 toward the upper right hand side. ing. A gas flow from the “air blower blower” 51 on the front side performs an operation of pressing down the vicinity of the edge of the sheet downward. Next, the “blast air blower” 52 on the left side and the “blast 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 outlet. One or a small number of ports are provided, and gas is blown obliquely upward in the direction of the arrow attached to each, and the flow of gas blown out from these “air blowing blowers” 52 and 53 is like an air curtain. It functions as a pseudo air divider. Further, the uppermost sheet is a wall on the upper surface side, and the support base and the lower sheet are walls on the lower surface side. In this way, a pseudo-closed space 10 is formed in which the six front, back, left, right, top, and bottom surfaces of the three-dimensional structure are closed, and the gas confined in the pseudo-closed space 10 due to gas retention characteristics, friction characteristics, gas partition characteristics, etc. It is possible to maintain or inflate a state inflated like a “paper balloon” together with the gas blown out from each “air blower” on the side and right side. In addition, in order to improve the closing performance 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 as necessary, and a third gas blocking guide is installed on the right side. 63 and a fourth gas cutoff guide 64 may be installed to enhance the shielding effect. In addition, although the said non-contact cut-out machine 91 becomes a figure shown with the non-contact adsorption chuck machine 60 using a several Bernoulli effect, each Example of the non-contact cut-out machine 91 shown to FIGS. The non-contact transfer machine 93 of the present invention operates so that the paper 42 at the end of the operation of the non-contact cutting machine 91 is received. Note that each of the “air blowing blowers” has a structure in which a large amount of gas sent from an electric blower or the like is fed through a pipe such as a vinyl chloride pipe and supplied from the blowout ports. Further, in the specification of this patent, when it is expressed as “compressed air nozzle”, the high pressure air compressed by the compressor is sent to the nozzle through an air regulator or the like through a vinyl pipe or the like. Means a “compressed air nozzle” that strongly injects the gas from a plurality of minute outlets having a diameter of about 1 mm.

FIG. 14 is a side view of a new non-contact transfer machine 93 used in the non-contact automatic page turning system 90 according to the sixth embodiment (Example 6) of the present invention. In FIG. 14, when performing the operation of raising the paper by the operation of the non-contact transporter 93 of the present invention, after binding a plurality of papers on which necessary contents are printed in advance, a designated company name and store are designated as necessary. An embodiment corresponding to the demand for “name printing” of a calendar for additionally printing names and advertisements on a part of each leaf is shown. In this example, there is a binding margin 17 on one side of the pre-stitched sheets. While the binding margin or the vicinity of the binding margin is being held by the fixing device 6, the transfer cylinder 9 of the flat table offset printing machine has a predetermined margin. For printing, the printer enters the range indicated by the print area 81 and performs additional printing on the uppermost paper 40. This printing area is usually in a range from the edge 18 of the calendar to the inside of about 150 mm. Immediately after printing, the cut-out operation of the non-contact cut-out machine 91 is performed on the printed uppermost paper 40. Each mechanism described with reference to FIGS. 2 a to 12 can be used for the non-contact cutting machine 91. In FIG. 14, the non-contact suction chuck device 60 lifts the paper by non-contact suction, and the position and shape of the uppermost paper reaches the position and shape indicated by 42. Receive this form. As described in the paragraph 0029, the air 51a is blown obliquely downward from the “air blowing blower” 51, and the gas 51b that is reflected by the uppermost sheet or the lower sheet bundle 2 and flows upward to the right hand flows. Here, when the uppermost sheet moves to the position and shape indicated by 42 to 43, the negative pressure generation region that generates buoyancy generated by the Bernoulli effect is gas along the flow of the gas 51b obliquely upward. The area on the fore edge side of the uppermost sheet formed under the flow 51b and cut out to the position 42 is generated by the effect of the pseudo-closed space 10 described in the paragraph 0029 together with the effect of the negative pressure generation area. It further rises by buoyancy and moves to the position and shape indicated by 43. As described in paragraph 0010, means for combining physical phenomena possessed by gas, such as the viscosity of gas, the frictional force generated between the gas and the paper, and the retention characteristics, are applied to this non-contact conveying machine, and The contact transporter 93 performs an operation that does not physically contact anything other than gas. Note that, as described above, the retention characteristic means that the gas does not easily flow or move when there is no 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 cut-out machine 91 of the present invention, it is possible to eliminate rubbing on the printing surface immediately after printing, and abruptly from the cut-out operation to the transfer operation period. Since a mechanism that can be controlled so as not to cause deformation of the paper is used, the non-contact transport 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 transfer machine 93 is established. In addition, each of the above-mentioned “air blowing blowers” has, for example, a metal or plastic pipe provided with a slit as a gas blowout opening, or a plurality of small holes, and gas from the blower is supplied from the side end of the pipe. It has a gas blower structure to be injected. In addition, the “blow air blower” installed on both sides can have a large opening and a structure in which the air beam is not concentrated. Or the structure which blows off the air which blows off from an electric blower directly or through piping can also be used. Furthermore, a hybrid structure in which a gas blown out from an electric blower is blown out from all or a part of each of the “blow air blowers” directly or through a pipe, and a mechanism that blows out a compressed gas from another “compressed air nozzle”, etc. This method can also be applied.

FIG. 15 relates to a seventh embodiment (Embodiment 7) of the present invention, and a non-contact conveying machine 93 that conveys a sheet of paper horizontally forward by a new non-contact conveying machine 93 used in the non-contact automatic turning system 90. FIG. FIG. 15 shows a situation in which one sheet from the sheet bundle 2 before printing is moved by a sheet feeding mechanism and arrives at a position indicated by 40 after the printing operation is completed. It is shown. The movable printer 8 can be installed so that it can move over the entire surface of the paper as indicated by an arrow 81, and retracts after the printing is completed. Next, after the non-contact cutting machine 91 of the present invention raises one sheet at the position indicated by 40 to the position 42, the sheet cutting operation is completed. The non-contact cutting machine 91 can be applied to each embodiment of the non-contact cutting machine 91 of the present invention shown in FIGS. The sheet at the end of the operation of the non-contact cutting machine 91 is cut off at the position 42, and is transferred to the sixth embodiment of the non-contact conveying machine 93 of the present invention described with reference to FIGS. At the indicated sheet position, the sheet is delivered to the operation of the “blow air blower” of the non-contact transporter 93. Further, the operation of this “air blower” will be described. In the seventh embodiment shown in FIG. 15, in the non-contact conveyance machine 93 of the present invention, a plurality of “air blowers” 11, 12, and 13 are installed in order to convey the paper at the position 43 in a non-contact manner. is there. The number of installed “air blowers” can be 2 to N, but FIG. 15 shows an example of three. Here, N is a positive integer. The gas blown out from these “air blowing blowers” forms the negative pressure generation regions 21, 22, and 23 generated by the Bernoulli effect, and the friction generation regions 31, 32, and 33 are formed by the viscosity of the gas. Is done. By the operation of these mechanisms, the sheet is further raised from the position 43 by the buoyancy generated by the negative pressure generation region. When the frictional area is reached, the sheet is conveyed in the direction of the arrow indicated by the dotted line 5 by the frictional force with the gas. As shown in this example, the gas blown out from the “blowing air blowers” 11, 12, and 13 flows along the locus indicated by the dotted line 5, and after the paper is conveyed to the position and shape indicated by 44, the “blowing air” It is transported further forward by the operation of the “blowers” 12 and 13, falls before the stopper 50 on the support base 1, and is placed at the position 49. In addition, during the period immediately before the conveyance of each sheet of paper, the gas flow is maintained at the top of each sheet, so the buoyancy due to the pressure difference generated by the Bernoulli effect caused by this gas flow , The above-mentioned individual sheets are prevented from falling abruptly. Specifically, in the sheet immediately before the position indicated by 49, the gas blown out from the “air blower” flows along the locus indicated by the dotted line 5, but gradually flows along the support base. When the sheet moves to the position, air flows on the upper surface side of the sheet, and buoyancy is generated, so that each sheet does not suddenly fall on the support base. In this embodiment, the negative pressure generation region and the friction generation region are not continuously connected. However, if the interval between adjacent nozzles is set to be sufficiently shorter than the length of the sheet, the negative pressure generation region and the friction generation region are conveyed. Since the negative pressure generation effect and the friction generation effect described above are sufficiently exerted on the sheet, an operation equivalent to the case where each negative pressure generation region and the friction generation region are continuously connected is performed. As described above, it is possible to realize the non-contact conveyance machine 93 that maintains high quality without soiling the paper immediately after printing by the conveyance method using the non-contact conveyance machine 93 of the present invention. In the case of transporting a sheet of paper, in order to stabilize the paper during transport, the non-contact suction chuck machine 60 is arranged in a two-dimensional plane instead of the structure in which the chuck is arranged in a straight line as shown in FIG. It may be replaced with a structured.

FIG. 16 relates to a seventh embodiment (Embodiment 7) of the present invention, and is a top view of a non-contact conveying machine 93 that conveys a workpiece horizontally forward by a new non-contact conveying machine used in the non-contact automatic turning system 90. It is. As shown in FIG. 15, the printing machine 8 may be installed so as to be able to move on the paper, or may be installed so that printing can be performed on a part of the paper. The unprinted sheet bundle 2 may be placed under the support 1 and the uppermost sheet may be moved to the position 40 before printing by an appropriate known sheet carry-in device. In the non-contact conveyance device of the present invention, as described in paragraph 0031, the paper cut out after printing is further raised by the buoyancy generated by the negative pressure generation region and delivered to the operation of the non-contact conveyance device 93 of the present invention. The sheet is further raised, and the sheet is delivered to the operation of the “blowing air blower” of the non-contact transporter 93 at the sheet position indicated by 43. The sheet is transported to a position indicated by 44 by the operation of the “blowing air blowing device” 11 or 12, and further sent to the position before the stopper 50 on the support base 1 by the operation of the “blowing air blowing device” 12 or 13. However, it falls and fits in position 49. The “blow air blowers” 11, 12, 13 have, for example, a metal or plastic pipe provided with a slit as a gas blower or a plurality of small holes, and gas is injected from the side end of the pipe. “Blowing air blower”. Note that this gas can be injected by using a gas piped and supplied from an electric blower.

FIG. 17 relates to an eighth embodiment (Embodiment 8) of the present invention, which is a new non-contact transfer machine 93 used in the non-contact automatic turning system 90, which is a non-contact transfer machine 93 that transfers a workpiece horizontally forward. FIG. In this embodiment shown in FIG. 17, after binding a plurality of sheets preprinted with necessary contents, a calendar that additionally prints a specified company name, store name, advertisement, etc. on a part of each leaf as necessary An example corresponding to the demand for “name printing” is shown. Further, there is a binding margin 17 on one side of the pre-stitched sheets, and the additional printing is performed by pressing the binding margin or the vicinity of the binding margin with the fixing device 6. For this additional printing, a flat table offset printing machine, which is standard in the industry, is used. In FIG. 17, the transfer cylinder 9 has entered the sheet bundle 2 to perform the additional printing on the uppermost sheet. The transfer cylinder 9 of the flat table offset printing machine enters a range indicated by a printing area 81 for predetermined printing and performs additional printing on the uppermost sheet 40. As described with reference to FIG. 14 in the paragraph 0030, this printing region is usually in the range from the edge 18 of the calendar to the inside of about 150 mm. For this additional printing, for example, an ink jet printer can be used. Immediately after the completion of this additional printing, as described with reference to FIG. 15 in the paragraph 0031, the paper immediately after the completion of printing is raised to the position 42 by the operation of the non-contact cutting machine 91 and is cut off, as shown in FIGS. Then, the sheet is delivered to the embodiment 6 of the non-contact conveyance machine 93 of the present invention described above and further lifted, and the sheet is conveyed by the “blow air blower” of the non-contact conveyance machine 93 at the position of the sheet indicated by 43. Handed over to action. In order to convey the sheet just after printing, in FIG. 17, a plurality of “blowing air blowers” 11, 12, 13, 14, 15 are installed in the operation of the non-contact conveying machine 93. Although a plurality of “N blow air blowers” can be installed in a number of 2 to N, FIG. 17 shows an example of five. In the example of FIG. 17, the negative pressure generation regions 21, 22, 23, 24, and 25 generated by the Bernoulli effect are formed so as to be continuously connected, and the friction generation regions 31, 32, and 33 due to the viscosity of the gas are included. , 34 and 35 also show an embodiment formed so as to be continuously connected. The paper delivered to the eighth embodiment of the non-contact transporter 93 continues to the negative pressure areas 21, 22, 23 and the friction areas 31, 32, 33 generated by the “blowing air blowers” 11, 12, and 13. With the function, the sheet starts to rise and advance, and is sequentially guided to the shapes and positions of 44 and 45. In the eighth embodiment, a “compressed air nozzle” 13c is installed to be used together with the “air blower” 13, and the compressed gas 13d is used as an extreme to support the transport operation of thick, heavy, and stiff paper. It erupts for a short period. The paper continues to advance by the functions of the negative pressure areas 24 and 25 and the friction areas 34 and 35 generated by the “air blowing blowers” 14 and 15, and the paper is sequentially guided to the shapes and positions of 46, 47 and 48. In this embodiment, the sheet finally fits on the position 49 on the shooter 7. In this process, when the frictional area is reached, the sheet is conveyed in the direction of arrow 5 by the frictional force with the gas. In addition, during the period immediately before the conveyance of each sheet of paper, the flow of gas is maintained at the top of each sheet, so that due to the buoyancy due to the pressure difference generated by the Bernoulli effect caused by this gas flow , It is possible to suppress a sudden fall of the individual sheets. Specifically, the sheet just before it fits in the shooter is at a position 47 to 48, and the gas blown out from the “air blower blower” 15 flows down substantially vertically as indicated by the dotted line 5 and flows to the shooter. Since it gradually flows along the shooter's inclination as it approaches, when the paper moves from the 47 position to the 49 position, there is an air flow on the back side of the reversed paper, and buoyancy is generated. Will no longer fall into the shooter or collide. As shown in this example, the gas blown out from the “blowing air blowers” 11, 12, 13, 14, and 15 flows along the locus indicated by the dotted line 5 and indicates that an arbitrary conveyance 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. Although an example is shown that is formed so as to be connected continuously, as described in the example of FIG. 15, even when not connected continuously, the interval between adjacent nozzles is sufficiently shorter than the paper length. The operation equivalent to the above is possible. Further, in FIG. 17, in the paragraph 0030, gas is supplied from each of the “blower air blowers” mentioned in the description of the side view of the embodiment 6 of the non-contact transfer machine 93 of the present invention shown in FIG. Also shown is an embodiment of a method such as a hybrid structure that uses a mechanism for blowing compressed gas from another “compressed air nozzle” together with a structure for blowing. Specifically, with respect to the “air blowing blower” 51, a hybrid structure with a mechanism for injecting high-pressure air from a plurality of nozzles by using a “compressed air nozzle” 51c is shown as an example. In addition, with regard to the “blowing air blowers” 52 and 53, “compressed air nozzles” 52c and 53c are installed on the left and right, respectively, and a hybrid structure with a mechanism for injecting high-pressure air from a plurality of nozzles is also used here. It is shown as an example. By using this hybrid structure, in the case of thick and hard paper, it is possible to achieve more stable operation by controlling the air volume and strength of two kinds of gas of the hybrid mechanism or the ejection time. On the other hand, for thin and light paper, stable operation can be achieved by performing control to shorten the ejection time.

FIG. 18 is a top view of a mechanism for conveying a workpiece horizontally forward by a new non-contact conveyance machine 93 used in the non-contact automatic turning system 90 according to an eighth embodiment (Embodiment 8) of the present invention. In FIG. 18, in the non-contact conveying machine 93 of the present invention, the topmost sheet 40 that has been cut out is cut out from the sheet bundle 2 by the non-contact cutting-out machine 91 of the present invention after printing is completed, and then the non-contact of the present invention. It is transferred to the transport machine 93 and further transported sequentially to the position indicated by the dotted line 49 by the eighth embodiment of the non-contact transport machine of the present invention shown in FIG. As in the example described in the paragraph 0032, “Blowing Air Blowers” 11, 12, 13, 14, and 15 have various pipes provided with slits as gas outlets or a plurality of small holes provided on the pipe side. It has a nozzle structure in which gas is injected from the end. Further, as described in the section “0036” above, regarding the “air blowing blowers” 51, 52, 53, and 13, a “compressed air nozzle” is used together, and a mechanism for injecting high-pressure air from a plurality of nozzles is used. Although the hybrid structure is shown as an embodiment, the place where the hybrid structure is applied is not limited to this embodiment. In addition, the gas supplied from the electric blower can be used for the gas injection by each of the “blowing air blowers”. The fixing device 6 can be constituted by a nip mechanism that moves up and down. The function of this non-contact automatic page-rolling system is completed until all pages of the calendar are transported to the shooter, but when the name printing is completed, the calendar is leaned against this shooter and stopped, and then the shooter slides down. In this case, the sheet bundle that has been placed in the lower storage box and loaded in the storage box and whose name has been printed is taken out and the process ends.

A non-contact automatic turning system that cuts out the paper immediately after printing by the printing machine, performs the takeover operation to the transport mechanism, and further performs the non-contact operation of the entire mechanism for transporting the paper is realized. Applicable to all printing applications that need to be read. In particular, it can be installed in various printing machines as a mechanism that can prevent the occurrence of smudges on paper immediately after printing. Furthermore, the present invention can be applied to a mechanism that transports a high-precision film-like workpiece or a thin plate workpiece in a non-contact manner as a workpiece other than paper. In addition, with regard to calendar name printing, since there are many limitations on the conventional automatic pager, its spread has been limited. The situation that continues to be involved in the risk of getting involved in hands and forced to work harshly has been achieved, and a system that can overcome this situation has been realized. Can be helpful. In addition, the cutting mechanism and the transport mechanism of the automatic page turning system according to the present invention can be used to print each page of a book bound on one side when digitizing bookbinding books, old books, literature, etc., for which demand has been increasing in recent years. It can also be applied to the turning mechanism of each sheet of paper at the time of electronic copying with a scanner. It can also be applied for stable operation of high-speed page turning of thin and soft paper.
