【Technical Field】 【0001】 The present invention relates to an apparatus for transporting an object to be transported and a method of operating the transport apparatus. 【Background Art】 【0002】 When packaging articles such as medical instruments and drugs, an attached document such as an instruction manual may be enclosed in the package of the article. Further, for example, when packaging articles such as glass plates, metal plates, and films, paper, film, or the like may be sandwiched between the articles as interleaving paper for protecting the articles. 【0003】 In recent years, in the packaging and bundling of articles, there has been a demand for automating the operation of transporting an object to be transported, such as a thin plate-like object like an attached document or interleaving paper, to a predetermined position. 【0004】 For example, Patent Document 1 describes a paper sheet feeding device including a magazine rack that holds a plurality of paper sheets in a stacked state on a plurality of support claws protruding inward from the outer shape of the paper sheet, and a drawing device that adsorbs the lower surface side of the lowermost paper sheet held in the magazine rack and draws it downward, and an air ejection device that blows air onto the upper surface side of the paper sheet drawn by the drawing device. Patent Document 2 describes an interleaving paper supply device that supplies interleaving paper used by being inserted between thin plate-like products when stacking the thin plate-like products, which adsorbs the uppermost interleaving paper in the stacked interleaving paper group from above with a suction pad, lifts it upward, transports the interleaving paper in the adsorbed state, and supplies it, and the suction pads are provided in two or two rows arranged in the longitudinal direction of the interleaving paper, and these are integrally moved up and down and moved to a predetermined position, and further, at least one of the two suction pads or at least one row of the two rows of suction pads is provided with vibration means for vibrating in the vertical direction. 【Prior Art Documents】 【Patent Documents】 【0005】 [Patent Document 1] Japanese Patent Application Publication No. 5-310334 [Patent Document 2] Japanese Patent Publication No. 2000-177864 [Overview of the Initiative] [Problems that the invention aims to solve] 【0006】 In the apparatuses described in Patent Documents 1 and 2, the objects to be transported, such as paper pieces and films, are supplied to the apparatus in a stacked state. However, when attempting to hold and transport the objects one by one, the apparatus may end up holding multiple objects at once, leading to product defects or transport problems. Furthermore, in the apparatuses described in Patent Documents 1 and 2, depending on the state of the objects to be transported, such as folded paper pieces (e.g., folded in half or thirds) or booklet-shaped paper pieces, it was difficult to reliably hold the objects and transport them to the desired location. 【0007】 The present invention has been made in view of the above circumstances, and its object is to provide a method for operating a conveying device and a conveying device that can hold and convey objects one by one. [Means for solving the problem] 【0008】 A method for operating a transport device that has solved the above problem is a method for operating a device that transports an object to be transported, having a first suction part and a second suction part, characterized by comprising: a suction step of attaching the first suction part and the second suction part to the object to be transported; a first suction part moving step of moving the first suction part upward and such that the horizontal distance between the first suction part and the second suction part is reduced; and a second suction part moving step of moving the second suction part upward. 【0009】 In the conveying device operation method of the present invention, it is preferable that in the first suction part movement step, the first suction part is moved closer to the second suction part by 10% or more of the horizontal distance between the center of the first suction part and the center of the second suction part. 【0010】 In the conveying device operation method of the present invention, it is preferable that in the first suction part movement step, the first suction part is moved horizontally toward the second suction part by a distance equal to or greater than the radius of the circumscribed circle of the suction surface of the first suction part. 【0011】 In the conveying device operation method of the present invention, it is preferable to have a spraying step in which gas is sprayed onto the object to be conveyed. 【0012】 In the conveying device operation method of the present invention, it is preferable to have a static electricity removal step for removing static electricity from the object to be conveyed. 【0013】 In the conveying device operation method of the present invention, the first suction part is located on one side, the second suction part is located on the other side, the device has a first regulating mechanism on one side of the first suction part, and a second regulating mechanism on the other side of the second suction part, and it is preferable to bring the first regulating mechanism into contact with the object to be conveyed during the first suction part movement step, and to bring the second regulating mechanism into contact with the object to be conveyed during the second suction part movement step. 【0014】 In the conveying device operation method of the present invention, the first suction part is located on one side, the second suction part is located on the other side, the device has a regulating mechanism on the other side of the first suction part and on one side of the second suction part, and it is preferable to bring the regulating mechanism into contact with the object to be conveyed in at least one of the first suction part movement step and the second suction part movement step. 【0015】 The conveying device that has been able to solve the above problem is a device for conveying an object to be conveyed, and has a first suction part and a second suction part, the first suction part has a first movement mechanism for moving the first suction part in a first movement direction, the second suction part has a second movement mechanism for moving the second suction part in a second movement direction, the first movement direction has a vertical component and a horizontal component, and the second movement direction has a vertical component. 【0016】 In the conveying device of the present invention, it is preferable that the first moving mechanism moves the first suction part so that it approaches the second suction part by 10% or more of the horizontal distance between the center of the first suction part and the center of the second suction part. 【0017】 In the conveying device of the present invention, it is preferable that the first moving mechanism moves the first suction part horizontally toward the second suction part by a distance equal to or greater than the radius of the circumscribed circle of the suction surface of the first suction part. 【0018】 In the conveying device of the present invention, it is preferable to further have a spraying device that sprays gas onto the object to be conveyed. 【0019】 In the conveying device of the present invention, it is preferable to further have a static eliminator that removes static electricity from the object to be conveyed. 【0020】 In the conveying device of the present invention, it is preferable that the first suction part is located on one side, the second suction part is located on the other side, the first regulating mechanism is located on one side of the first suction part, and the second regulating mechanism is located on the other side of the second suction part. 【0021】 In the conveying device of the present invention, the first suction part is located on one side, the second suction part is located on the other side, and it is preferable that the regulating mechanism is located on the other side of the first suction part and on one side of the second suction part. [Effects of the Invention] 【0022】 According to the method of operating a conveying device of the present invention, there are an adsorption step of adsorbing a first adsorption part and a second adsorption part to an object to be conveyed, a first adsorption part moving step of moving the first adsorption part upward and in a horizontal direction so that the distance between the first adsorption part and the second adsorption part decreases, and a second adsorption part moving step of moving the second adsorption part upward. As a result, the first adsorption part moves closer to the second adsorption part, and at least a part of the object to be conveyed adsorbed by the first adsorption part and the second adsorption part is in a bent state. Therefore, air can easily enter the lower surface of the object to be conveyed adsorbed by the first adsorption part and the second adsorption part, and it is possible to easily separate other substances adhering to the lower side surface of the object to be conveyed 100 due to static electricity or the like, and it becomes easy to hold and convey the objects to be conveyed one by one. Further, according to the method of operating a conveying device of the present invention, since air can easily enter the lower surface of the object to be conveyed, not only a piece of paper without folding but also a folded piece of paper or a booklet-shaped piece of paper can be conveyed. 【0023】 Further, according to the conveying device of the present invention, the first adsorption part has a first moving mechanism that moves the first adsorption part in a first moving direction, the second adsorption part has a second moving mechanism that moves the second adsorption part in a second moving direction, the first moving direction has a vertical direction component and a horizontal direction component, and the second moving direction has a vertical direction component. Thus, the moving direction of the first adsorption part and the moving direction of the second adsorption part can be made different. Therefore, at least a part of the object to be conveyed adsorbed by the first adsorption part and the second adsorption part can be bent, air can easily enter the lower surface of the object to be conveyed, and other substances adhering to the lower side surface of the object to be conveyed 100 due to static electricity or the like are easily separated, and it becomes easy to hold and convey the objects to be conveyed one by one. Further, since air can easily enter the lower surface of the object to be conveyed, a piece of paper without folding, a folded piece of paper, or a booklet-shaped piece of paper can be conveyed by the conveying device of the present invention. 【Brief Description of the Drawings】 【0024】 [Figure 1] It shows a schematic diagram (partial cross-sectional view) of a conveying device in an embodiment of the present invention.

However, the present invention is not limited by the following embodiments, and it is of course possible to appropriately modify and implement it within the scope that can conform to the gist of the foregoing and following descriptions, and all of them are included in the technical scope of the present invention. In each drawing, for convenience, hatching, reference numerals of members, etc. may be omitted, but in such cases, reference shall be made to the specification and other drawings. Also, the dimensions of various members in the drawings may be different from the actual dimensions because priority is given to facilitating the understanding of the features of the present invention. 【0026】 First, the operation method of the conveying device of the present invention will be described. 【0027】 FIG. 1 is a schematic diagram of a conveying device 1 in an embodiment of the present invention. As shown in FIG. 1, the operation method of the conveying device of the present invention is an operation method of a device 1 having a first adsorption part 11 and a second adsorption part 12 and conveying a conveyance object 100, and includes an adsorption process of adsorbing the first adsorption part 11 and the second adsorption part 12 to the conveyance object 100, a first adsorption part movement process of moving the first adsorption part 11 upward and making the horizontal distance D1 between the first adsorption part 11 and the second adsorption part 12 approach, and a second adsorption part movement process of moving the second adsorption part 12 upward. 【0028】 The conveying device 1 is a device that conveys the object to be conveyed 100 to a predetermined position. Examples of the object to be conveyed 100 include paper, film, sheets, thin sheet-like materials such as resin plates and metal plates. Among these, the object to be conveyed 100 is preferably paper. Since paper has a certain degree of breathability in the thickness direction, if the device 1 is used to hold and convey the object to be conveyed 100 by sucking in air, multiple sheets of paper will be sucked into the suction part in a stacked state, which is likely to cause conveying problems. With the conveying device operation method of the present invention, even if the object to be conveyed 100 is breathable paper, it becomes easier to hold and convey the object to be conveyed 100 one by one. The paper of the object to be conveyed 100 may be unfolded paper pieces, folded paper pieces, or booklet-shaped paper pieces. 【0029】 It is preferable that the objects to be transported 100 are stacked in multiples in the thickness direction of the objects to be transported 100. Specifically, it is preferable that the transport device 1 has a mounting table 40 and that multiple objects to be transported 100 are stacked on the mounting table 40. By stacking multiple objects to be transported 100, it is possible to increase the efficiency of transporting the objects to be transported 100 by the transport device 1. 【0030】 As shown in Figure 1, the conveying device 1 has a first suction part 11 and a second suction part 12. The conveying device 1 can hold the object to be conveyed 100 by attaching the first suction part 11 and the second suction part 12 to the object to be conveyed 100. 【0031】 The first suction part 11 and the second suction part 12 preferably adsorb the object to be transported 100 by suction. In other words, it is preferable that the first suction part 11 and the second suction part 12 each have suction holes. The number of suction holes in the first suction part 11 and the second suction part 12 may be one or multiple. 【0032】 Figure 2 is a schematic diagram of the suction process in the operation method of the conveying device 1. As shown in Figure 2, in the suction process, the first suction part 11 and the second suction part 12 are attached to the object to be conveyed 100. 【0033】 In the suction process, it is preferable to attach the first suction part 11 and the second suction part 12 to the upper surface of the object to be conveyed 100. By attaching the first suction part 11 and the second suction part 12 to the upper surface of the object to be conveyed 100, the object to be conveyed 100 can be stably suctioned by the first suction part 11 and the second suction part 12. 【0034】 In the adsorption process, the first adsorption part 11 and the second adsorption part 12 may be adsorbed onto the object to be transported 100 simultaneously, or the first adsorption part 11 may be adsorbed onto the object to be transported 100 before the second adsorption part 12, or the second adsorption part 12 may be adsorbed onto the object to be transported 100 before the first adsorption part 11. In particular, it is preferable to adsorb the first adsorption part 11 and the second adsorption part 12 onto the object to be transported 100 simultaneously in the adsorption process. By adsorbing the first adsorption part 11 and the second adsorption part 12 onto the object to be transported 100 simultaneously, the time required for the transport device 1 to transport the object to be transported 100 to a predetermined position can be shortened. 【0035】 Figure 3 is a schematic diagram of the first suction part movement step in the operation method of the conveying device 1. In Figure 3, the position of the first suction part 11 during the suction step is indicated by a dashed line. As shown in Figure 3, in the first suction part movement step, the first suction part 11 is moved upward and the horizontal distance D1 between the first suction part 11 and the second suction part 12 is brought closer. In other words, in the first suction part movement step, with the first suction part 11 and the second suction part 12 attached to the object to be conveyed 100, the first suction part 11 is moved upward and closer to the second suction part 12. 【0036】 In the first suction part movement step, by moving the first suction part 11 upward and reducing the horizontal distance D1 between the first suction part 11 and the second suction part 12, at least a portion of the object to be transported 100 bends and sags, making it easier for air to enter the area beneath the object to be transported 100. This makes it easier to detach other objects adhering to the underside of the object to be transported 100 due to static electricity, etc., and makes it easier to lift the objects to be transported 100 one by one using the first suction part 11 and the second suction part 12. Furthermore, when multiple objects to be transported 100 are stacked, air can easily enter between the uppermost object to be transported 100 and the objects to be transported 100 located below it, making it less likely for multiple objects to be lifted by static electricity, etc. 【0037】 Figure 4 is a schematic diagram of the second suction part movement process in the operation method of the conveying device 1. In Figure 4, the position of the second suction part 12 during the suction process is indicated by a dashed line. As shown in Figure 4, in the second suction part movement process, the second suction part 12 is moved upward. 【0038】 In the suction process, the first suction part 11 and the second suction part 12 are attached to the object to be transported 100. In the first suction part movement process, the first suction part 11 attached to the object to be transported 100 is moved. In the second suction part movement process, the second suction part 12 attached to the object to be transported 100 is moved. As a result, the object to be transported 100, which is attached to the first suction part 11 and the second suction part 12, moves upward, and the object to be transported 100 can be transported to a predetermined position. 【0039】 The second suction part movement step may be performed simultaneously with the first suction part movement step, but it is preferable to perform it after the first suction part movement step. Performing the second suction part movement step after the first suction part movement step makes it easier to move the objects to be transported 100 by holding each object 100 individually with the first suction part 11 and the second suction part 12. 【0040】 By moving the first suction part 11 upward in the first suction part movement step and reducing the horizontal distance D1 between the first suction part 11 and the second suction part 12, and by moving the second suction part 12 upward in the second suction part movement step, at least a portion of the object to be transported 100 between the part that the first suction part 11 and the part that the second suction part 12 are adsorbing becomes sagging, making it easier for air to enter the underside of the object to be transported 100, making it easier for other objects adhering to the underside of the object to be transported 100 due to static electricity or the like to detach, and making it easier to move the object to be transported 100 while holding each one individually with the first suction part 11 and the second suction part 12. As a result, the object to be transported 100 is easier to transport, and it is possible to handle the object to be transported 100 such as unfolded paper pieces, folded paper pieces, and booklet-shaped paper pieces. In Figure 4, an example is shown where the area between the portion of the object to be transported 100 that is adsorbed by the first suction part 11 and the portion that is adsorbed by the second suction part 12 is curved downwards in a convex shape. However, at least a portion of the area between the portion of the object to be transported 100 that is adsorbed by the first suction part 11 and the portion that is adsorbed by the second suction part 12 may be curved upwards in a convex shape, or it may be curved both downwards and upwards in a convex shape. 【0041】 As shown in Figures 2 and 3, in the first adsorption part movement step, it is preferable to move the first adsorption part 11 closer to the second adsorption part 12 by at least 10% of the horizontal distance between the center P1 of the first adsorption part 11 and the center P2 of the second adsorption part 12. In other words, in the first adsorption part movement step, it is preferable to move the first adsorption part 11 closer to the second adsorption part 12 by at least 10% of the horizontal length from the center P1 of the first adsorption part 11 to the center P2 of the second adsorption part 12. Note that the center P1 of the first adsorption part 11 is the center of the adsorption surface of the first adsorption part 11, and the center P2 of the second adsorption part 12 is the center of the adsorption surface of the second adsorption part 12. By moving the first suction part 11 so that it is closer to the second suction part 12 by more than 10% of the horizontal distance between the center P1 of the first suction part 11 and the center P2 of the second suction part 12, the object to be transported 100 being held by the first suction part 11 and the second suction part 12 can be made more flexible, and air can be easily drawn under the object to be transported 100. 【0042】 In the first suction part movement step, it is preferable to move the first suction part 11 toward the second suction part 12 such that it approaches by 10% or more of the horizontal distance between the center P1 of the first suction part 11 and the center P2 of the second suction part 12, more preferably by 15% or more, and even more preferably by 20% or more. By setting the lower limit of the distance the first suction part 11 moves toward the second suction part 12 within the above range, the object to be transported 100 being held by the first suction part 11 and the second suction part 12 can be easily bent, and the object to be transported 100 can be easily deflected. Furthermore, the upper limit of the distance the first suction part 11 moves toward the second suction part 12 in the first suction part movement step is not particularly limited, but for example, it can be 80% or less, 75% or less, or 70% or less of the horizontal distance between the center P1 of the first suction part 11 and the center P2 of the second suction part 12. 【0043】 In the first suction part movement step, it is preferable to move the first suction part 11 horizontally toward the second suction part 12 by a distance equal to or greater than the radius of the circumscribed circle of the suction surface of the first suction part 11. In other words, in the first suction part movement step, it is preferable to move the first suction part 11 toward the second suction part 12 by a distance equal to or greater than the radius of the smallest circle tangent to the outer edge of the suction surface when viewed from a direction perpendicular to the suction surface of the first suction part 11. By moving the first suction part 11 horizontally toward the second suction part 12 by a distance equal to or greater than the radius of the circumscribed circle of the suction surface of the first suction part 11, the object to be transported 100 that is being adsorbed by the first suction part 11 and the second suction part 12 becomes more prone to bending and flexing, making it easier for air to enter beneath the object to be transported 100. 【0044】 In the first suction part movement step, it is preferable to move the first suction part 11 toward the second suction part 12 by a distance of 1.1 times or more the radius of the circumscribed circle of the suction surface of the first suction part 11, more preferably by a distance of 1.3 times or more, and even more preferably by a distance of 1.5 times or more. By setting the lower limit of the distance the first suction part 11 moves toward the second suction part 12 within the above range, the object to be transported 100 being held by the first suction part 11 and the second suction part 12 becomes sufficiently flexible. The upper limit of the distance the first suction part 11 moves toward the second suction part 12 in the first suction part movement step is not particularly limited and can be set according to the distance between the first suction part 11 and the second suction part 12. 【0045】 Furthermore, it is preferable to have a spraying step in which gas is sprayed onto the object to be transported 100. That is, in the adsorption part movement step, it is preferable to move at least one of the first adsorption part 11 and the second adsorption part 12 while spraying gas onto the object to be transported 100. By having a spraying step, gas is sprayed onto the object to be transported 100, which has been bent by the movement of the first adsorption part 11 in the first adsorption part movement step, making it less likely for other objects, such as other objects to be transported 100, to adhere to the lower surface of the object to be transported 100 due to static electricity or the like. As a result, the transport of the object to be transported 100 becomes smoother. 【0046】 In the spraying process, it is preferable to spray gas onto the lower surface of the object to be conveyed 100. By spraying gas onto the lower surface of the object to be conveyed 100, the gas comes into contact with the lower surface of the object to be conveyed 100, which tends to attract other substances due to static electricity, making it difficult for other substances to adhere to the object to be conveyed 100. 【0047】 Examples of gases that can be sprayed onto the object to be conveyed 100 in the spraying process include air, nitrogen gas, oxygen gas, and carbon dioxide gas. Among these, air is preferred as the gas sprayed onto the object to be conveyed 100. By using air as the gas sprayed onto the object to be conveyed 100, it is less likely to damage the object to be conveyed 100, and since there is no need to introduce special equipment in the spraying process, it is possible to reduce the operating costs of the conveying device 1. 【0048】 It is preferable to perform the spraying process from before the adsorption process until the second adsorption unit movement process. By performing the spraying process from before the adsorption process until the second adsorption unit movement process, it is possible to maintain a state in which other substances are less likely to adhere to the object 100 during the process of transporting the object 100 to a predetermined position. Therefore, it becomes easier to transport the object 100 one by one. 【0049】 Furthermore, it is preferable to have a static electricity removal step for removing static electricity from the object to be transported 100. By having a static electricity removal step after the first suction part movement step, the movement of the first suction part 11 in the first suction part movement step removes static electricity from the bent object to be transported 100, making it less likely for other objects to adhere to the object to be transported 100 due to static electricity. Therefore, it becomes easier to transport the object to be transported 100 smoothly. 【0050】 Methods for removing static electricity from the object 100 to be transported during the static elimination process include spraying a static electricity removal fluid onto the object 100, and bringing a static elimination brush, static elimination string, electrodes, etc., into contact with the object 100. Among these, it is preferable to perform the static elimination process by spraying a static electricity removal fluid onto the object 100 to be transported. Performing the static elimination process by spraying a static electricity removal fluid onto the object 100 to be transported makes it less likely to damage the object 100 and makes it easier to remove static electricity from the entire object 100. 【0051】 It is preferable to perform the static elimination process from before the suction process until the second suction part movement process. By performing the static elimination process from before the suction process until the second suction part movement process, it is possible to maintain a state in which other substances are less likely to adhere to the objects 100 during the transport process of the objects 100 due to static elimination, making it easier to transport the objects 100 one by one. 【0052】 The spraying process and the static elimination process may be performed simultaneously. In other words, it is preferable to spray a gas containing the static electricity removal fluid onto the object to be conveyed 100 from before the adsorption process until the second adsorption unit movement process, and to perform the spraying process and the static elimination process simultaneously. Performing the spraying process and the static elimination process simultaneously makes it easier to enhance the effect of making it difficult for other substances to adhere to the object to be conveyed 100. 【0053】 Figure 5 is a schematic diagram of the suction step in the operation method of the conveying device 1 in another embodiment, and Figure 6 is a schematic diagram of the second suction part movement step in the operation method of the conveying device 1. In Figures 5 and 6, the left side of the figure is one side, and the right side of the figure is the other side. 【0054】 As shown in Figures 5 and 6, the first suction part 11 is located on one side, and the second suction part 12 is located on the other side. The device 1 has a first regulating mechanism 111 on one side of the first suction part 11, and a second regulating mechanism 112 on the other side of the second suction part 12. It is preferable to bring the first regulating mechanism 111 into contact with the object to be transported 100 during the first suction part movement process, and to bring the second regulating mechanism 112 into contact with the object to be transported 100 during the second suction part movement process. By bringing the first regulating mechanism 111 into contact with the object to be transported 100 during the first suction part movement process, and bringing the second regulating mechanism 112 into contact with the object to be transported 100 during the second suction part movement process, after the first suction part 11 and the second suction part 12 move upward, the portion of the object to be transported 100 that is being suctioned by the first suction part 11 and the portion that is being suctioned by the second suction part 12 becomes more likely to bend upward in a convex shape. As a result, gaps are more likely to form on the underside of the object to be transported 100 that is being adsorbed by the first adsorption part 11 and the second adsorption part 12, making it less likely for other objects to adhere to the object to be transported 100. 【0055】 Furthermore, as shown in Figures 5 and 6, the first suction part 11 is located on one side, and the second suction part 12 is located on the other side. The device 1 has a regulating mechanism 110 located on the other side of the first suction part 11 and on one side of the second suction part 12. It is preferable to bring the regulating mechanism 110 into contact with the object to be transported 100 in at least one of the first suction part movement process and the second suction part movement process. By bringing the regulating mechanism 110 into contact with the object to be transported 100 in at least one of the first suction part movement process and the second suction part movement process, after the first suction part 11 and the second suction part 12 move upward, the portion of the object to be transported 100 between the portion adsorbed by the first suction part 11 and the portion adsorbed by the second suction part 12 tends to bend upward in a convex shape, making it easier to create a gap on the underside of the object to be transported 100. As a result, other objects are less likely to adhere to the underside of the object to be transported 100, and the objects to be transported 100 can be transported one by one. 【0056】 The regulating mechanisms 110, 111, and 212 contact the object to be transported 100 to prevent a portion of the object from moving upward, making it easier to arrange the object to be transported 100 into an appropriate shape after the suction part 11 and 212 have moved upward. Examples of the shapes of the regulating mechanisms 110, 111, and 212 include cylinders, polygonal prisms, cones, polygonal pyramids, hemispheres, and combinations thereof. 【0057】 The position of the regulating mechanism 110 is preferably higher than the height of the first adsorption section 11 and the second adsorption section 12 in the adsorption process, as shown in Figure 5, and lower than the height of the first adsorption section 11 in the first adsorption section movement process and the height of the second adsorption section 12 in the second adsorption section movement process, as shown in Figure 6. In other words, as shown in Figure 5, the distance between the mounting base 40 and the regulating mechanism 110 in the adsorption process is preferably greater than the distance between the mounting base 40 and the first adsorption section 11 and the distance between the mounting base 40 and the second adsorption section 12, and as shown in Figure 6, the distance between the mounting base 40 and the regulating mechanism 110 in the first adsorption section movement process and the second adsorption section movement process is preferably smaller than the distance between the mounting base 40 and the first adsorption section 11 and the distance between the mounting base 40 and the second adsorption section 12. By setting the position of the regulating mechanism 110 as described above, at least a portion of the object to be transported 100 becomes more likely to bend upward in a convex shape, making it less likely for other objects to adhere to the underside of the object to be transported 100, and thus facilitating the smooth transport of the object to be transported 100. 【0058】 Furthermore, similar to the regulating mechanism 110, it is preferable that the positions of the first regulating mechanism 111 and the second regulating mechanism 112 are higher than the heights of the first adsorption section 11 and the second adsorption section 12 in the adsorption process, and lower than the height of the first adsorption section 11 in the first adsorption section movement process and the height of the second adsorption section 12 in the second adsorption section movement process. 【0059】 Next, the conveying device of the present invention will be described. Note that in the following description, any parts that overlap with the above description will be omitted. 【0060】 As shown in Figure 1, the conveying device 1 of the present invention is a device 1 for conveying an object 100, and has a first suction part 11 and a second suction part 12, the first suction part 11 has a first moving mechanism 31 for moving the first suction part 11 in a first movement direction, and the second suction part 12 has a second moving mechanism 32 for moving the second suction part 12 in a second movement direction, the first movement direction has a vertical component and a horizontal component, and the second movement direction has a vertical component. 【0061】 The first moving mechanism 31 moves the first suction part 11 in the first moving direction. In other words, the first moving mechanism 31 moves the first suction part 11 in the first moving direction having a vertical component and a horizontal component. 【0062】 The second moving mechanism 32 moves the second adsorption part 12 in the second movement direction. In other words, the second moving mechanism 32 moves the second adsorption part 12 in the second movement direction which has a vertical component. 【0063】 In the conveying device 1, the first suction part 11 has a first movement mechanism 31 that moves the first suction part 11 in a first movement direction having a vertical component and a horizontal component, and the second suction part 12 has a second movement mechanism 32 that moves the second suction part 12 in a second movement direction having a vertical component. As a result, the first suction part 11 can be moved in the vertical and horizontal directions, and the second suction part 12 can be moved in the vertical direction. In other words, it is possible to move the first suction part 11 and the second suction part 12 in different directions. To put it another way, it is preferable that the movement direction of the first suction part 11 and the movement direction of the second suction part 12 are different. As a result, the conveying device 1 can be made such that the conveyed object 100 being held by the first suction part 11 and the second suction part 12 is bent, making it easier for air to enter the lower surface of the conveyed object 100, and making it easier for other objects attached to the lower surface of the conveyed object 100 due to static electricity, etc. to detach, thus making it easier to hold and convey the conveyed object 100 one by one. 【0064】 Preferably, the second movement direction does not have a horizontal component. In other words, it is preferable that the second movement mechanism 32 moves the second suction part 12 vertically and not horizontally. Because the second movement direction does not have a horizontal component, the first movement direction and the second movement direction tend to differ significantly, making it easier to cause the conveyed object 100, which is being held by the first suction part 11 and the second suction part 12, to bend significantly. 【0065】 As shown in Figures 2 and 3, it is preferable that the first moving mechanism 31 moves the first suction part 11 so that it approaches the second suction part 12 by at least 10% of the horizontal distance between the center P1 of the first suction part 11 and the center P2 of the second suction part 12. In other words, it is preferable that the first moving mechanism 31 moves the first suction part 11 so that it approaches the second suction part 12 by at least 10% of the horizontal length from the center P1 of the first suction part 11 to the center P2 of the second suction part 12. By moving the first suction part 11 so that it approaches the second suction part 12 by at least 10% of the horizontal distance between the center P1 of the first suction part 11 and the center P2 of the second suction part 12, the object to be conveyed 100 that is being adsorbed by the first suction part 11 and the second suction part 12 becomes more flexible, making it easier for air to enter underneath the object to be conveyed 100. 【0066】 The first moving mechanism 31 preferably moves the first suction part 11 toward the second suction part 12 by 10% or more of the horizontal distance between the center P1 of the first suction part 11 and the center P2 of the second suction part 12, more preferably by 15% or more, and even more preferably by 20% or more. By setting the lower limit of the distance the first moving mechanism 31 moves the first suction part 11 within the above range, it becomes easier to bend the object to be transported 100 that the first suction part 11 and the second suction part 12 are adsorbing, and it becomes possible to sufficiently deflect the object to be transported 100. Furthermore, the upper limit of the distance the first moving mechanism 31 moves the first suction part 11 is not particularly limited, but for example, it can be 80% or less, 75% or less, or 70% or less of the horizontal distance between the center P1 of the first suction part 11 and the center P2 of the second suction part 12. 【0067】 It is preferable that the first moving mechanism 31 moves the first suction part 11 horizontally toward the second suction part 12 by a distance equal to or greater than the radius of the circumscribed circle of the suction surface of the first suction part 11. In other words, it is preferable that the first moving mechanism 31 moves the first suction part 11 toward the second suction part 12 by a distance equal to or greater than the radius of the smallest circle tangent to the outer edge of the suction surface when viewed from a direction perpendicular to the suction surface of the first suction part 11. By moving the first suction part 11 horizontally toward the second suction part 12 by a distance equal to or greater than the radius of the circumscribed circle of the suction surface of the first suction part 11, the object to be transported 100 being adsorbed by the first suction part 11 and the second suction part 12 becomes more flexible, making it easier for air to enter beneath the object to be transported 100. 【0068】 The first moving mechanism 31 preferably moves the first suction part 11 closer to the second suction part 12 by a distance of 1.1 times or more the radius of the circumscribed circle of the suction surface of the first suction part 11, more preferably by a distance of 1.3 times or more, and even more preferably by a distance of 1.5 times or more. By setting the lower limit of the distance the first moving mechanism 31 moves the first suction part 11 within the above range, the object to be transported 100 being held by the first suction part 11 and the second suction part 12 becomes sufficiently flexible and prone to bending. The upper limit of the distance the first moving mechanism 31 moves the first suction part 11 is not particularly limited and can be set according to the distance between the first suction part 11 and the second suction part 12. 【0069】 As shown in Figures 1 to 4, it is preferable that the conveying device 1 also has a spraying device 60 for spraying gas onto the object to be conveyed 100. By having the spraying device 60, the conveying device 1 sprays gas onto the object to be conveyed 100, making it less likely for other objects to adhere to the lower surface of the object to be conveyed 100 due to static electricity or the like. As a result, the conveying device 1 can be made capable of smoothly conveying the object to be conveyed 100. 【0070】 The spraying device 60 preferably sprays gas onto the lower surface of the object to be conveyed 100. The lower surface of the object to be conveyed 100 is prone to other substances adhering to it due to static electricity, etc. By spraying gas onto the lower surface of the object to be conveyed 100, the gas comes into contact with the lower surface of the object to be conveyed 100, making it less likely for other substances to adhere to the object to be conveyed 100. 【0071】 Examples of gases that the spraying device 60 sprays onto the object to be conveyed 100 include air, nitrogen gas, oxygen gas, and carbon dioxide gas. Among these, air is preferred as the gas sprayed onto the object to be conveyed 100. By using air as the gas sprayed onto the object to be conveyed 100, it is possible to reduce the risk of damaging the object to be conveyed 100, and since there is no need to introduce special equipment in the spraying process, the cost of the conveying device 1 can be reduced. 【0072】 As shown in Figures 1 to 4, it is preferable to further have a static eliminator 70 for removing static electricity from the object 100 to be transported. The presence of the static eliminator 70 in the transporting device 1 removes static electricity from the object 100. As a result, it becomes less likely for other objects to adhere to the object 100 due to static electricity, making it easier to transport the object 100 smoothly. 【0073】 Examples of the static eliminator 70 include a nozzle for spraying static electricity removal fluid onto the object 100 to be transported, a static elimination brush, a static elimination string, electrodes, etc. Among these, the static eliminator 70 is preferably a nozzle for spraying static electricity removal fluid onto the object 100 to be transported. By having the static eliminator 70 be a nozzle for spraying static electricity removal fluid, it becomes easier to eliminate static electricity from the entire object 100 without damaging it. 【0074】 As shown in Figures 5 and 6, the first suction part 11 is located on one side, and the second suction part 12 is located on the other side. Preferably, the first restricting mechanism 111 is located on one side of the first suction part 11, and the second restricting mechanism 112 is located on the other side of the second suction part 12. Because the conveying device 1 has the first restricting mechanism 111 and the second restricting mechanism 112, the parts of the conveyed object 100 that are adsorbed by the first suction part 11 and the parts that are adsorbed by the second suction part 12 tend to bend upward in a convex shape, making it easier for a gap to be created on the underside of the conveyed object 100. Therefore, it is possible to enhance the effect of making it difficult for other objects to adhere to the conveyed object 100. 【0075】 Furthermore, as shown in Figures 5 and 6, the first suction part 11 is located on one side, the second suction part 12 is located on the other side, and it is preferable that the regulating mechanism 110 is located on the other side of the first suction part 11 and on the one side of the second suction part 12. Because the conveying device 1 has the regulating mechanism 110, the portion of the object to be conveyed 100 between the portion adsorbed by the first suction part 11 and the portion adsorbed by the second suction part 12 is more likely to bend upward in a convex shape, and a gap is more likely to form on the underside of the object to be conveyed 100. As a result, other objects are less likely to adhere to the underside of the object to be conveyed 100, and the objects to be conveyed 100 can be conveyed smoothly one by one. 【0076】 As described above, the conveying device operation method of the present invention is an operation method for a device that conveys an object to be conveyed, having a first suction part and a second suction part, and comprises a suction step of attaching the first suction part and the second suction part to the object to be conveyed, a first suction part moving step of moving the first suction part upward and reducing the horizontal distance between the first suction part and the second suction part, and a second suction part moving step of moving the second suction part upward. Because the conveying device operation method of the present invention has such steps, the first suction part moves closer to the second suction part, and at least a part of the object to be conveyed that is attached to the first and second suction parts becomes sagged. As a result, air can easily enter the lower surface of the object to be conveyed that is attached to the first and second suction parts, making it easier to detach other objects attached to the lower surface of the object to be conveyed 100 by static electricity, etc., and making it easier to hold and convey the objects one by one. Furthermore, with the conveying device operation method of the present invention, air can easily enter the underside of the object being conveyed, making it possible to convey not only unfolded paper pieces but also folded paper pieces and booklet-shaped paper pieces. 【0077】 Furthermore, the conveying device of the present invention is a device for conveying objects, and has a first suction part and a second suction part. The first suction part has a first movement mechanism for moving the first suction part in a first movement direction, and the second suction part has a second movement mechanism for moving the second suction part in a second movement direction. The first movement direction has a vertical component and a horizontal component, and the second movement direction has a vertical component. With this configuration, the conveying device of the present invention can be configured so that the direction of movement of the first suction part and the direction of movement of the second suction part are different. As a result, at least a part of the object being conveyed that is being held by the first and second suction parts can be bent, allowing air to easily enter the lower surface of the object being conveyed, and making it easier for other objects attached to the lower surface of the object being conveyed 100 by static electricity or the like to detach, making it easier to hold and convey the objects one by one. In addition, because air can easily enter the lower surface of the object being conveyed, even paper pieces that have not been folded, folded paper pieces, and booklet-shaped paper pieces can be conveyed by the conveying device of the present invention.
