Description

【Technical Field】 【0001】 The present invention relates to an apparatus for conveying an object to be conveyed and a method of operating the conveying apparatus. 【Background Art】 【0002】 When packaging articles such as medical devices 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, etc. 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 conveying an object to be conveyed, 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 stacked on a plurality of support claws protruding inside the outer shape of the paper sheet, and a drawing-out device that adsorbs the lower surface side of the lowermost paper sheet held in the magazine rack and draws it downward, and is characterized in that an air ejection device for blowing air onto the upper surface side of the paper sheet drawn out by the drawing-out device is provided. Patent Document 2 describes an interleaving paper supply device for supplying interleaving paper used by inserting it 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, conveys the interleaving paper in the adsorbed state, and supplies it. The suction pads are provided in two or two rows arranged in the longitudinal direction of the interleaving paper, and these are integrally moved in the vertical direction and positionally 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 project] [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】 The method for operating a transport device that has solved the above problem comprises a first suction part and a second suction part, and a mounting table on which an object to be transported is placed, wherein the mounting table has an upper surface, and comprises a suction step of attaching the first suction part and the second suction part to the object to be transported, and a suction part movement step of moving the first suction part and the second suction part upward, wherein in the suction step, when the first suction part and the second suction part are attached to the object to be transported placed on the mounting table, the suction surfaces of the first suction part and the second suction part are horizontal with respect to the upper surface of the mounting table, and in the suction part movement step, the suction surface of the first suction part is inclined toward the direction of the second suction part, and the suction surface of the second suction part is inclined toward the direction of the first suction part. 【0009】 In the present invention's method for operating a transport device, it is preferable that in the suction part movement step, the first suction part is moved upward before the second suction part, and the second suction part is moved upward after the first suction part has moved. 【0010】 In the present invention's method for operating the transport device, it is preferable to move the first suction part and the second suction part upward simultaneously during the suction part movement process. 【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 operating method of the present invention, it is preferable that the first suction part and the second suction part have bellows sections. 【0014】 In the conveying device operation method of the present invention, it is preferable to further have a contact portion that comes into contact with the object to be conveyed, and to bring the contact portion into contact with the object to be conveyed that is being held by the first and second suction portions during the suction portion movement process. 【0015】 The conveying device that has been able to solve the above problem is a device for conveying an object to be conveyed, and comprises a first suction part and a second suction part, and a mounting table on which the object to be conveyed is placed, wherein the mounting table has an upper surface, and in a downward state in which the first suction part and the second suction part are attached to the object to be conveyed placed on the mounting table, the suction surfaces of the first suction part and the suction surfaces of the second suction part are horizontal with respect to the upper surface of the mounting table, and in an upward state in which the first suction part and the second suction part attached to the object to be conveyed are pulled upward, the suction surface of the first suction part is inclined toward the direction of the second suction part, and the suction surface of the second suction part is inclined toward the direction of the first suction part. 【0016】 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. 【0017】 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. 【0018】 In the conveying device of the present invention, it is preferable that the first suction section and the second suction section have bellows sections. 【0019】 In the conveying device of the present invention, it is preferable that the first suction part and the second suction part further have contact parts that come into contact with the end of the object being conveyed that is being suctioned. [Effects of the Invention] 【0020】 The present invention provides a method for operating a transport device, comprising an adsorption step of adsorbing a first adsorption part and a second adsorption part onto an object to be transported, and an adsorption part movement step of moving the first adsorption part and the second adsorption part upward. In the adsorption step, when the first adsorption part and the second adsorption part are adsorbed onto an object to be transported placed on a mounting table, the adsorption surfaces of the first adsorption part and the second adsorption part are horizontal with respect to the upper surface of the mounting table. In the adsorption part movement step, the adsorption surface of the first adsorption part is inclined toward the second adsorption part, and the adsorption surface of the second adsorption part is inclined toward the first adsorption part. As a result, in the adsorption step, the first adsorption part and the second adsorption part are easily adsorbed onto the object to be transported, and in the adsorption part movement step, the object to be transported, which is adsorbed by the first adsorption part and the second adsorption part, is easily curved into a mountain-like shape. Therefore, air can easily enter the underside of the object being transported, which is being held by the first and second suction parts, making it easier to detach other objects adhering to the underside of the object 100 due to static electricity, etc., and making it easier to hold and transport the objects one by one. Furthermore, with the transport device operation method of the present invention, air can easily enter the underside of the object being transported, so it is possible to transport not only unfolded paper pieces, but also folded paper pieces and booklet-shaped paper pieces. 【0021】 Further, according to the conveying device of the present invention, in the descending state where the first suction portion and the second suction portion are adsorbed to the object to be conveyed placed on the mounting table, the suction surfaces of the first suction portion and the second suction portion are horizontal with respect to the upper surface portion of the mounting table. In the ascending state where the first suction portion and the second suction portion adsorbed to the object to be conveyed are pulled upward, the suction surface of the first suction portion is inclined toward the second suction portion, and the suction surface of the second suction portion is inclined toward the first suction portion. As a result, in the descending state, the first suction portion and the second suction portion are more likely to adsorb to the object to be conveyed, and in the ascending state, the object to be conveyed adsorbed by the first suction portion and the second suction portion is more likely to be curved in a mountain shape. Therefore, air easily enters the lower surface of the object to be conveyed adsorbed by the first suction portion and the second suction portion, and foreign substances adhering to the lower side surface of the object to be conveyed 100 due to static electricity or the like are more likely to be separated, making it easier to hold and convey the objects to be conveyed one by one. Also, since air easily enters the lower surface of the object to be conveyed, even a piece of paper without folding, a piece of paper with folding, or a booklet-shaped piece of paper can be conveyed by the conveying device of the present invention. 【Brief Description of Drawings】 【0022】 [Figure 1] It shows a schematic diagram (partial cross-sectional view) of the conveying device in one embodiment of the present invention. [Figure 2] It shows a schematic diagram (partial cross-sectional view) of the suction process in the operation method of the conveying device shown in FIG. 1. [Figure 3] It shows a schematic diagram (partial cross-sectional view) of the suction portion movement process in the operation method of the conveying device shown in FIG. 1. 【Embodiments for Carrying Out the Invention】 【0023】 The present invention will be described in more detail below based on the embodiments described below. However, the present invention is not limited by the embodiments described below, and it is certainly possible to implement it with appropriate modifications within the scope that is consistent with the spirit of the preceding and following descriptions, and all such modifications are included within the technical scope of the present invention. In addition, hatching and component reference numerals may be omitted in the drawings for convenience, in which case please refer to the specification or other drawings. Furthermore, the dimensions of various components in the drawings may differ from the actual dimensions, as priority has been given to helping to understand the features of the present invention. 【0024】 First, the operating method of the conveying device of the present invention will be described. 【0025】 Figure 1 is a schematic diagram of a transport device 1 in one embodiment of the present invention. The method of operating the transport device 1 of the present invention, as shown in Figure 1, comprises a first suction part 11 and a second suction part 12, and a mounting table 40 on which an object to be transported 100 is placed, wherein the mounting table 40 has an upper surface portion 41, and comprises a suction step of attaching the first suction part 11 and the second suction part 12 to the object to be transported 100, and a suction part moving step of moving the first suction part 11 and the second suction part 12 upward. In the suction process, when the first suction part 11 and the second suction part 12 are attached to the object to be transported 100 placed on the mounting table 40, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 are horizontal with respect to the upper surface 41 of the mounting table 40. In the suction part movement process, the suction surface 21 of the first suction part 11 is inclined toward the second suction part 12, and the suction surface 22 of the second suction part 12 is inclined toward the first suction part 11. 【0026】 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. 【0027】 The platform 40 is used to place the object to be transported 100. The platform 40 has an upper surface 41 on which the object to be transported 100 is placed. 【0028】 The materials that make up the mounting base 40 include metal, synthetic resin, rubber, and wood. Among these, it is preferable that the material making up the mounting base 40 be metal. The durability of the mounting base 40 is increased when the material making up the mounting base 40 is metal. 【0029】 It is preferable that the objects to be transported 100 are stacked in the thickness direction. Specifically, it is preferable that multiple objects to be transported 100 are stacked on the upper surface 41 of 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 suction part movement process in the operation method of the conveying device 1. As shown in Figure 3, in the suction part movement process, the first suction part 11 and the second suction part 12 are moved upward. The suction part movement process is performed after the suction process. By moving the first suction part 11 and the second suction part 12 upward, the object to be conveyed 100 that is being held by the first suction part 11 and the second suction part 12 moves upward, and the object to be conveyed 100 can be conveyed to a predetermined position. 【0036】 As shown in Figure 2, in the suction process, when the first suction part 11 and the second suction part 12 are attached to the object to be transported 100 placed on the mounting table 40, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 are horizontal with respect to the upper surface 41 of the mounting table 40. As shown in Figure 3, in the suction part movement process, the suction surface 21 of the first suction part 11 is inclined toward the second suction part 12, and the suction surface 22 of the second suction part 12 is inclined toward the first suction part 11. In other words, the orientation of the suction surface 21 of the first suction part 11 is different between the suction process and the suction part movement process, and the orientation of the suction surface 22 of the second suction part 12 is different between the suction process and the suction part movement process. 【0037】 In the suction process, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 are horizontal to the upper surface 41 of the mounting table 40, which makes it easier for the entire suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 to come into contact with the upper surface of the object to be transported 100 placed on the mounting table 40. As a result, the first suction part 11 and the second suction part 12 are more easily attracted to the object to be transported 100. 【0038】 During the suction part movement process, the suction surface 21 of the first suction part 11 is inclined to face the direction of the second suction part 12, and the suction surface 22 of the second suction part 12 is inclined to face the direction of the first suction part 11. As a result, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 face inward. Therefore, as shown in Figure 3, in the object 100 being carried by the first suction part 11 and the second suction part 12, the portion between the first suction part 11 and the second suction part 12 curves upward in a convex shape, making it easier for the object 100 to curve into a mountain-like shape. When the object 100 is curved into a mountain-like shape, air can easily enter underneath it, making it easier to detach other objects attached to the underside of the object 100 due to static electricity, etc., and making it easier to move the object 100 while holding each one individually with the first suction part 11 and the second suction part 12. As a result, the transport of the object 100 is made easier, and it is possible to handle the transport of objects 100 such as unfolded paper pieces, folded paper pieces, and booklet-shaped paper pieces. 【0039】 As shown in Figure 3, in the suction part movement process, the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface 41 of the mounting base 40 is preferably 5 degrees or more, more preferably 10 degrees or more, even more preferably 20 degrees or more, and even more preferably 30 degrees or more. By setting the lower limit of the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface 41 of the mounting base 40 to the above range, the object to be transported 100 being suctioned by the first suction part 11 and the second suction part 12 is more likely to curve in a mountain-like shape, making it easier for air to enter the underside of the object to be transported 100. Furthermore, in the suction part movement process, the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface 41 of the mounting base 40 is preferably 80 degrees or less, more preferably 70 degrees or less, and even more preferably 60 degrees or less. By setting the upper limit of the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface 41 of the mounting base 40 to the above range, the object to be transported 100 being held by the first suction part 11 and the second suction part 12 becomes less likely to bend excessively, and damage such as bending of the object to be transported 100 becomes less likely. 【0040】 Similar to the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface 41 of the mounting base 40, in the suction part movement process, the angle θ2 between the suction surface 22 of the second suction part 12 and the upper surface 41 of the mounting base 40 is preferably 5 degrees or more, more preferably 10 degrees or more, even more preferably 20 degrees or more, and even more preferably 30 degrees or more. Furthermore, in the suction part movement process, the angle θ2 between the suction surface 22 of the second suction part 12 and the upper surface 41 of the mounting base 40 is preferably 80 degrees or less, more preferably 70 degrees or less, and even more preferably 60 degrees or less. 【0041】 In the suction part movement process, the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface 41 of the mounting base 40, and the angle θ2 between the suction surface 22 of the second suction part 12 and the upper surface 41 of the mounting base 40, may be different, but it is preferable that they be the same. By having the same angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface 41 of the mounting base 40, and the same angle θ2 between the suction surface 22 of the second suction part 12 and the upper surface 41 of the mounting base 40, it becomes easier to adjust the degree of curvature of the object to be transported 100 that is being held by the first suction part 11 and the second suction part 12, and it becomes easier to transport the object to be transported 100 stably. 【0042】 In the suction part movement process, it is preferable to move the first suction part 11 upward before the second suction part 12, and move the second suction part 12 upward after the first suction part 11 has moved. In the suction part movement process, by moving the second suction part 12 upward after the first suction part 11 has moved upward, when only the first suction part 11 moves upward, only the portion of the object to be transported 100 that is being held by the first suction part 11 will be lifted upward. As a result, air can easily enter the area below the object to be transported 100 from the portion of the object to be transported 100 that is being held by the first suction part 11, thereby increasing the effect of easily detaching other objects that are adhering to the lower surface of the object to be transported 100 due to static electricity, etc. 【0043】 Furthermore, it is preferable to move the first suction part 11 and the second suction part 12 upward simultaneously during the suction part movement process. By moving the first suction part 11 and the second suction part 12 upward simultaneously during the suction part movement process, it is possible to shorten the time required to transport the object to be transported 100 to a predetermined position. 【0044】 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 unit movement step, it is preferable to move the first adsorption unit 11 and the second adsorption unit 12 upward 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 bent due to the movement of the first adsorption unit 11 and the second adsorption unit 12, 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. 【0045】 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. 【0046】 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. 【0047】 It is preferable to perform the spraying process from before the adsorption process until the adsorption unit movement process. By performing the spraying process from before the adsorption process until the 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. 【0048】 Furthermore, it is preferable to have a static electricity removal process for removing static electricity from the object to be transported 100. By having a static electricity removal process, the first suction part 11 and the second suction part 12 move upward, removing 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. 【0049】 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. 【0050】 It is preferable to perform the static elimination process from before the suction process until the suction part movement process. By performing the static elimination process from before the suction process until the suction part movement process, it is possible to maintain a state in which other objects 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. 【0051】 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 adsorption part 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. 【0052】 As shown in Figure 2, in the suction process, when the first suction part 11 and the second suction part 12 are attached to the object to be transported 100 placed on the mounting table 40, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 are horizontal to the upper surface 41 of the mounting table 40. As shown in Figure 3, in the suction part movement process, the suction surface 21 of the first suction part 11 is inclined toward the second suction part 12, and the suction surface 22 of the second suction part 12 is inclined toward the first suction part 11. To achieve this configuration, for example, the first suction part 11 and the second suction part 12 may have a bellows section 80, or they may have a link mechanism composed of multiple link members and joints, and a drive mechanism such as an air cylinder that drives in the vertical direction. The link mechanism is a mechanical element in which multiple combined link members operate relative to each other to convert an input operation into a different operation. Since the first suction section 11 and the second suction section 12 have a bellows section 80, a link mechanism, and a vertical drive mechanism, it becomes easier to switch the orientation of the suction surface 21 of the first suction section 11 and the suction surface 22 of the second suction section 12 so that they are in different orientations during the suction process and the suction section movement process. 【0053】 In particular, as shown in Figures 1 to 3, it is preferable that the first suction part 11 and the second suction part 12 have bellows sections 80. The presence of bellows sections 80 in both the first suction part 11 and the second suction part 12 makes it easier to change the orientation of the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12. Therefore, in the suction process, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 are made horizontal to the upper surface 41 of the mounting base 40, and in the suction part movement process, the suction surface 21 of the first suction part 11 is tilted toward the second suction part 12, and the suction surface 22 of the second suction part 12 is tilted toward the first suction part 11. Furthermore, because the first suction part 11 and the second suction part 12 each have a bellows section 80, the first suction part 11 and the second suction part 12 are less likely to be damaged even if the orientation of the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 is repeatedly changed. 【0054】 As shown in Figures 1 to 3, the conveying device 1 further has a contact portion 90 that contacts the object to be conveyed 100, and it is preferable to bring the contact portion 90 into contact with the object to be conveyed 100 that is being held by the first suction portion 11 and the second suction portion 12 during the suction portion movement process. By bringing the contact portion 90 into contact with the object to be conveyed 100 that is being held by the first suction portion 11 and the second suction portion 12 during the suction portion movement process, if other objects are attached to the object to be conveyed 100 that is being lifted by the movement of the first suction portion 11 and the second suction portion 12 due to static electricity or the like, the contact portion 90 can detach and drop the attached objects, making it easier to convey the object to be conveyed 100 one by one by the first suction portion 11 and the second suction portion 12. 【0055】 The shape of the contact portion 90 can be, for example, a rod, a plate, or a claw. Among these, the shape of the contact portion 90 is preferably a claw shape. The claw shape of the contact portion 90 makes it easier for the contact portion 90 to come into contact with the end of the object to be transported 100 that is being held by the first suction portion 11 and the second suction portion 12, and makes it easier to remove other objects that are attached to the object to be transported 100 due to static electricity or the like. 【0056】 The contact portion 90 is formed integrally with the mounting base 40, and may be part of the mounting base 40, or it may be a separate component from the mounting base 40 and fixed to the mounting base 40, or it may be fixed to a part of the conveying device 1 other than the mounting base 40. In particular, it is preferable that the contact portion 90 is a separate component from the mounting base 40 and fixed to the mounting base 40. Because the contact portion 90 is a separate component from the mounting base 40 and fixed to the mounting base 40, it becomes easy to replace the contact portion 90 with one that is suitable for the thickness, shape, material, etc. of the object to be conveyed 100, and it also becomes easier to adjust the position of the contact portion 90. As a result, it becomes possible to convey the object to be conveyed 100 one by one using the first suction portion 11 and the second suction portion 12. 【0057】 The number of contact points 90 may be one, but it is preferable to have multiple. Having multiple contact points 90 allows the contact points 90 to make contact at multiple locations on the end of the object to be conveyed 100, making it easier to separate other objects that are attached to the object to be conveyed 100 by static electricity or the like. 【0058】 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. 【0059】 As shown in Figures 1 to 3, the conveying device 1 of the present invention is a device 1 for conveying an object 100, and comprises a first suction part 11 and a second suction part 12, and a mounting table 40 on which the object 100 is placed, the mounting table 40 having an upper surface 41, and in a downward state in which the first suction part 11 and the second suction part 12 are attached to the object 100 placed on the mounting table 40, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 are horizontal with respect to the upper surface 41 of the mounting table 40, and in an upward state in which the first suction part 11 and the second suction part 12 attached to the object 100 are pulled upward, the suction surface 21 of the first suction part 11 is inclined toward the direction of the second suction part 12, and the suction surface 22 of the second suction part 12 is inclined toward the direction of the first suction part 11. 【0060】 As shown in Figure 2, the downward state is a state in which the first suction part 11 and the second suction part 12 are attached to the object to be transported 100 which is placed on the mounting table 40. In other words, the downward state is a state in which the first suction part 11 and the second suction part 12 are attached to the object to be transported 100 which is placed on the mounting table 40, and the object to be transported 100 is not being moved upward by the first suction part 11 and the second suction part 12. 【0061】 In the lowering state, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 are horizontal to the upper surface 41 of the mounting table 40. This allows the entire suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 to easily come into contact with the upper surface of the object to be transported 100 placed on the mounting table 40, making it easier for the first suction part 11 and the second suction part 12 to adhere to the object to be transported 100. 【0062】 As shown in Figure 3, the rising state is a state in which the first suction part 11 and the second suction part 12, which are attached to the object to be transported 100, are pulled upward. In other words, the rising state is a state in which the object to be transported 100, to which the first suction part 11 and the second suction part 12 are attached, is moving upward. 【0063】 In the upward position, the suction surface 21 of the first suction part 11 is inclined to face the direction of the second suction part 12, and the suction surface 22 of the second suction part 12 is inclined to face the direction of the first suction part 11, so that the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 face inward. As a result, the object to be transported 100 being held by the first suction part 11 and the second suction part 12 tends to curve into a mountain-like shape, allowing air to easily enter underneath the object to be transported 100, making it easier to detach other objects attached to the underside of the object to be transported 100 due to static electricity, etc., 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. 【0064】 As shown in Figures 1 to 3, 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. 【0065】 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. 【0066】 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. 【0067】 As shown in Figures 1 to 3, 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. 【0068】 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. 【0069】 As shown in Figures 1 to 3, it is preferable that the first suction part 11 and the second suction part 12 have a bellows section 80. Having a bellows section 80 on the first suction part 11 and the second suction part 12 makes it easier to change the orientation of the suction surface 21 of the first suction part 11 and the orientation of the suction surface 22 of the second suction part 12, and makes it less likely for the first suction part 11 and the second suction part 12 to be damaged even if their orientations are repeatedly changed. 【0070】 As shown in Figures 1 to 3, it is preferable that the conveying device 1 has a contact portion 90 that contacts the end of the object to be conveyed 100 that is being held by the first suction portion 11 and the second suction portion 12. Because the conveying device 1 has a contact portion 90, if other objects are attached to the lower surface of the object to be conveyed 100 due to static electricity or the like, the contact portion 90 contacts the end of the object to be conveyed 100, making it easier to separate and drop the other objects from the object to be conveyed 100. Therefore, it becomes easier to smoothly convey the objects 100 one by one using the first suction portion 11 and the second suction portion 12. 【0071】 As described above, the present invention provides a method for operating a transport device comprising a first suction part and a second suction part, and a platform on which an object to be transported is placed, wherein the platform has an upper surface, and comprises a suction step of attaching the first suction part and the second suction part to the object to be transported, and a suction part movement step of moving the first suction part and the second suction part upward, wherein in the suction step, when the first suction part and the second suction part are attached to the object to be transported placed on the platform, the suction surfaces of the first suction part and the second suction part are horizontal with respect to the upper surface of the platform, and in the suction part movement step, the suction surface of the first suction part is inclined toward the direction of the second suction part, and the suction surface of the second suction part is inclined toward the direction of the first suction part. Because the conveying device operation method of the present invention has such a process, the first suction part and the second suction part can easily adhere to the object to be conveyed in the suction process, and the object to be conveyed that is being held by the first suction part and the second suction part can easily bend into a curved shape in the suction part movement process. As a result, air can easily enter the underside of the object to be conveyed that is being held by the first suction part and the second suction part, making it easier to detach other objects that are adhering to the underside of the object to be conveyed 100 due to 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 to be conveyed, so it is possible to convey not only unfolded paper pieces, but also folded paper pieces and booklet-shaped paper pieces. 【0072】 Furthermore, the conveying device of the present invention is a device for conveying an object, and comprises a first suction part and a second suction part, and a mounting table on which the object to be conveyed is placed. The mounting table has an upper surface, and in a downward state in which the first suction part and the second suction part are attached to the object to be conveyed placed on the mounting table, the suction surfaces of the first suction part and the second suction part are horizontal with respect to the upper surface of the mounting table. In an upward state in which the first suction part and the second suction part attached to the object to be conveyed are pulled upward, the suction surface of the first suction part is inclined toward the direction of the second suction part, and the suction surface of the second suction part is inclined toward the direction of the first suction part. With this configuration of the conveying device of the present invention, in the downward state the first suction part and the second suction part are more likely to attach to the object to be conveyed, and in the upward state the object to be conveyed in which the first suction part and the second suction part are attached is more likely to curve in a mountain-like shape. Therefore, air can easily enter the underside of the object being transported, which is being held by the first and second suction parts. This makes it easier for other objects attached to the underside of the object 100 by static electricity or the like to detach, making it easier to hold and transport each object individually. Furthermore, because air can easily enter the underside of the object being transported, even unfolded paper pieces, folded paper pieces, and booklet-shaped paper pieces can be transported by the transport device of the present invention.
