Hereinafter, the present invention will be explained in more detail based on the following embodiments. However, the present invention is not limited by the following embodiments, and modifications may be made as appropriate within the scope that fits the spirit of the above and below. Of course, additional implementations are also possible, and all of these are included within the technical scope of the present invention. In addition, in each drawing, hatching, member codes, etc. may be omitted for convenience, but in such cases, the specification and other drawings shall be referred to. Further, the dimensions of various members in the drawings are given priority to help understanding the features of the present invention, and therefore may differ from actual dimensions.

First, the method of operating the conveying device of the present invention will be explained.

FIG. 1 is a schematic diagram of a conveying device 1 in an embodiment of the present invention. As shown in FIG. 1, the transport device operating method of the present invention includes a first suction section 11, a second suction section 12, and a mounting table 40 on which an object to be transported 100 is placed. The mounting table 40 has an upper surface part 41, and a suction step of sucking the first suction part 11 and the second suction part 12 to the conveyed object 100; In the suction step, the first suction portion 11 and the second suction portion 12 are moved upward to the conveyed object 100 placed on the mounting table 40. In the state where the second suction part 12 is suctioning, 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 part 41 of the mounting table 40, and the suction part In the moving process, the suction surface 21 of the first suction section 11 is inclined toward the second suction section 12, and the suction surface 22 of the second suction section 12 is inclined toward the first suction section 11. There is.

The transport device 1 is a device that transports a transport target 100 to a predetermined position. Examples of the conveyed object 100 include paper, a film, a sheet, a thin plate-like object such as a resin plate, and a metal plate. Among these, it is preferable that the conveyed object 100 is paper. Since paper has a certain degree of breathability in the thickness direction, when using the device 1 in which the suction section holds and conveys the conveyed object 100 by suctioning air, multiple pieces of paper are suctioned in a stacked state. This tends to cause transport problems. With the transport device operating method of the present invention, even if the objects 100 to be transported are breathable paper, it becomes easy to hold and transport the objects 100 one by one. Note that the paper of the object to be conveyed 100 may be a piece of paper that has not been folded, a piece of paper that has been subjected to a folding process, or a piece of paper that is in the form of a booklet.

The mounting table 40 is used to place the object 100 to be transported. The mounting table 40 has an upper surface portion 41, and the object to be transported 100 is placed on the upper surface portion 41.

Examples of materials constituting the mounting table 40 include metal, synthetic resin, rubber, wood, and the like. Among these, the material constituting the mounting table 40 is preferably metal. Since the material constituting the mounting table 40 is metal, the durability of the mounting table 40 is increased.

It is preferable that a plurality of objects 100 to be transported are stacked in the thickness direction of the objects 100 to be transported. Specifically, it is preferable that a plurality of conveyed objects 100 are stacked on the upper surface portion 41 of the mounting table 40 . By stacking the plurality of conveyance objects 100, it becomes possible to increase the efficiency with which the conveyance objects 100 are conveyed by the conveyance device 1.

As shown in FIG. 1, the transport device 1 includes a first suction section 11 and a second suction section 12. The transport device 1 can hold the object to be transported 100 by adsorbing the first suction section 11 and the second suction section 12 to the object to be transported 100 .

It is preferable that the first suction section 11 and the second suction section 12 suction the conveyed object 100 by suction. That is, it is preferable that the first suction section 11 and the second suction section 12 each have a suction hole. The number of suction holes that the first suction section 11 and the second suction section 12 have may be one or more.

FIG. 2 is a schematic diagram of the suction step in the method of operating the transport device 1. As shown in FIG. 2, in the suction step, the first suction section 11 and the second suction section 12 are suctioned onto the conveyed object 100.

In the suction step, it is preferable that the first suction section 11 and the second suction section 12 are suctioned onto the upper surface of the conveyed object 100 . Since the first suction section 11 and the second suction section 12 adsorb the upper surface of the object to be transported 100, the object to be transported 100 can be stably adsorbed by the first suction section 11 and the second suction section 12. can.

In the suction step, the first suction section 11 and the second suction section 12 may be suctioned to the conveyed object 100 at the same time, or the first suction section 11 may be suctioned to the conveyed object 100 before the second suction section 12. Alternatively, the second suction section 12 may be suctioned onto the conveyed object 100 before the first suction section 11. Among these, it is preferable that the first suction section 11 and the second suction section 12 are simultaneously suctioned to the conveyed object 100 in the suction step. By simultaneously adsorbing the first suction section 11 and the second suction section 12 to the object to be transported 100, the time required for transporting the object to be transported 100 to a predetermined position in the transport device 1 can be shortened.

FIG. 3 is a schematic diagram of the suction part moving step in the method of operating the conveyance device 1. As shown in FIG. 3, in the suction part moving step, the first suction part 11 and the second suction part 12 are moved upward. The suction part moving process is performed after the suction process. By moving the first suction section 11 and the second suction section 12 upward, the conveyed object 100 that the first suction section 11 and the second suction section 12 are suctioning moves upward and is conveyed to a predetermined position. The object 100 can be transported.

As shown in FIG. 2, in the suction process, when the first suction section 11 and the second suction section 12 are suctioning the conveyed object 100 placed on the mounting table 40, the first suction section 11 is The suction surface 21 and the suction surface 22 of the second suction part 12 are horizontal to the upper surface part 41 of the mounting table 40, and as shown in FIG. 21 is inclined toward the second suction section 12 , and the suction surface 22 of the second suction section 12 is inclined toward the first suction section 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. It's different.

In the suction process, the suction surface 21 of the first suction section 11 and the suction surface 22 of the second suction section 12 are horizontal to the upper surface 41 of the mounting table 40, so that the conveyance placed on the mounting table 40 is The entire suction surface 21 of the first suction section 11 and the suction surface 22 of the second suction section 12 can easily come into contact with the upper surface of the object 100. As a result, the first suction section 11 and the second suction section 12 can easily suction onto the conveyed object 100.

In the suction part moving process, the suction surface 21 of the first suction part 11 is inclined so as to face the second suction part 12, and the suction surface 22 of the second suction part 12 is tilted so as to face the direction of the second suction part 12. By being inclined so as to face the direction, the suction surface 21 of the first suction section 11 and the suction surface 22 of the second suction section 12 face inward. Therefore, as shown in FIG. 3, in the conveyed object 100 that the first suction section 11 and the second suction section 12 are suctioning, the part between the first suction section 11 and the second suction section 12 is moved upward. The conveyed object 100 is easily curved into a mountain shape. By curving the conveyed object 100 into a mountain shape, air can easily enter the underside of the conveyed object 100, making it easier to separate other objects attached to the lower surface of the conveyed object 100 due to static electricity or the like. This makes it easier to move the conveyed objects 100 while being held one by one by the first suction section 11 and the second suction section 12. As a result, it is easy to transport the object 100, and it is possible to handle objects 100 such as unfolded paper pieces, folded paper pieces, and booklet-shaped paper pieces. be.

As shown in FIG. 3, in the suction part moving step, the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface part 41 of the mounting table 40 is preferably 5 degrees or more, and preferably 10 degrees or more. It is more preferably at least 20 degrees, even more preferably at least 30 degrees. By setting the lower limit of the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface part 41 of the mounting table 40 to the above range, the first suction part 11 and the second suction part 12 can be suctioned. The object 100 to be transported is easily curved into a mountain shape, and air can easily enter the lower side of the object 100 to be transported. Further, in the suction part moving step, the angle θ1 between the suction surface 21 of the first suction part 11 and the upper surface part 41 of the mounting table 40 is preferably 80 degrees or less, more preferably 70 degrees or less. , 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 part 41 of the mounting table 40 to the above range, the first suction part 11 and the second suction part 12 can be adsorbed. The conveyed object 100 is less likely to bend excessively, and damage such as bending of the conveyed object 100 is less likely to occur.

Similar to the angle θ1 between the suction surface 21 of the first suction section 11 and the top surface 41 of the mounting table 40, in the suction section movement process, the suction surface 22 of the second suction section 12 and the top surface 41 of the mounting table 40 The angle θ2 formed by the angle θ2 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. In addition, in the suction part moving step, the angle θ2 between the suction surface 22 of the second suction part 12 and the upper surface part 41 of the mounting table 40 is preferably 80 degrees or less, and more preferably 70 degrees or less. , more preferably 60 degrees or less.

In the suction part moving process, the angle θ1 between the suction surface 21 of the first suction part 11 and the top surface 41 of the mounting table 40 and the angle θ1 formed between the suction surface 22 of the second suction part 12 and the top surface 41 of the mounting table 40 are The angle θ2 may be different, but preferably the same. The angle θ1 between the suction surface 21 of the first suction section 11 and the top surface 41 of the mounting table 40 is the same as the angle θ2 between the suction surface 22 of the second suction section 12 and the top surface 41 of the mounting table 40. The angle makes it easier to adjust the degree of curvature of the object to be transported 100 that is attracted by the first suction section 11 and the second suction section 12, and it becomes easier to transport the object to be transported 100 stably.

In the suction part moving step, it is preferable that the first suction part 11 is moved upward before the second suction part 12, and the second suction part 12 is moved upward after the first suction part 11 is moved. . In the suction part moving step, the second suction part 12 moves upward after the first suction part 11 moves upward, so that when only the first suction part 11 moves upward, the first suction part 11 and Of the object to be transported 100 that is being attracted by the second suction section 12, only the portion of the object to be transported 100 on the side that is being adsorbed by the first suction section 11 is lifted upward. Therefore, air tends to enter the lower part of the conveyed object 100 from the side of the conveyed object 100 that is attracted by the first suction unit 11, and the air is attached to the lower side of the conveyed object 100 due to static electricity or the like. The effect of making it easier to release other objects can be enhanced.

Moreover, in the suction part moving step, it is also preferable to simultaneously move the first suction part 11 and the second suction part 12 upward. In the suction part moving step, by simultaneously moving the first suction part 11 and the second suction part 12 upward, it is possible to shorten the time required to transport the object to be transported 100 to a predetermined position.

Furthermore, it is preferable to include a spraying step of spraying gas onto the conveyed object 100. That is, in the suction part moving step, it is preferable to move the first suction part 11 and the second suction part 12 upward while blowing gas onto the conveyed object 100. By including the spraying step, the gas is blown onto the conveyed object 100 that has been bent due to the movement of the first suction section 11 and the second suction section 12, and the conveyed object 100, which is different from this conveyed object 100, etc. Other objects are less likely to adhere to the lower surface of the conveyed object 100 due to static electricity or the like. As a result, it becomes easier to transport the object 100 smoothly.

In the spraying step, it is preferable to spray the gas onto the lower surface of the object to be transported 100 . By blowing gas onto the lower surface of the conveyed object 100, the gas hits the lower surface of the conveyed object 100, which tends to attract other objects due to static electricity, etc., thereby making it difficult for other objects to adhere to the conveyed object 100. be able to.

Examples of the gas to be sprayed onto the conveyed object 100 in the spraying step include air, nitrogen gas, oxygen gas, carbon dioxide gas, and the like. Among these, it is preferable that the gas blown onto the conveyed object 100 is air. Since the gas to be blown onto the conveyed object 100 is air, it is difficult to damage the conveyed object 100, and there is no need to introduce special equipment in the spraying process, thereby reducing the cost for operating the conveying device 1. becomes possible.

The spraying step is preferably performed from before the adsorption step to the adsorption part moving step. By performing the spraying process from before the suction process to the suction part moving process, it is possible to maintain a state in which foreign objects are less likely to adhere to the conveyance target 100 during the process of conveying the conveyance target 100 to a predetermined position. Therefore, it becomes easier to transport the objects 100 to be transported one by one.

Furthermore, it is preferable to include a static electricity removal step for removing static electricity from the conveyed object 100. By including the static electricity removal process, static electricity is removed from the transported object 100 that has been bent by moving the first suction section 11 and the second suction section 12 upward, and other objects are not attached to the transported object 100 due to static electricity. Adhesion is less likely to occur. Therefore, it becomes easier to transport the object 100 to be transported smoothly.

Examples of methods for removing static electricity from the object to be transported 100 in the static elimination process include a method of injecting static electricity removal fluid onto the object to be transported 100, a method of bringing a static elimination brush, a static elimination string, an electrode, etc. into contact with the object to be transported 100, and the like. It will be done. Among these, it is preferable that the static electricity removal step is performed by spraying static electricity removal fluid onto the conveyed object 100. By performing the static electricity removal step by spraying the static electricity removal fluid onto the object to be transported 100, the object to be transported 100 is less likely to be damaged, and the entire object to be transported 100 can be easily neutralized.

It is preferable that the static elimination process is performed before the suction process and up to the suction part moving process. By performing the static elimination process from before the suction process to the suction unit moving process, it is possible to maintain a state in which other objects are difficult to adhere to the conveyed object 100 during the conveyance process of the conveyed object 100 by eliminating static electricity. It becomes easier to transport the object 100 to be transported.

The spraying process and the static elimination process may be performed simultaneously. That is, it is preferable to inject the gas containing the static electricity removal fluid onto the conveyed object 100 from before the adsorption process to the adsorption part moving process, and to perform the spraying process and the static electricity removal process simultaneously. By performing the spraying step and the static elimination step at the same time, it becomes easier to increase the effect of making it difficult for other objects to adhere to the conveyed object 100.

As shown in FIG. 2, in the suction process, when the first suction section 11 and the second suction section 12 are suctioning the conveyed object 100 placed on the mounting table 40, the first suction section 11 is The suction surface 21 and the suction surface 22 of the second suction section 12 are horizontal to the upper surface 41 of the mounting table 40, and as shown in FIG. is inclined toward the second suction section 12, and the suction surface 22 of the second suction section 12 is inclined toward the first suction section 11, for example. The second suction portion 12 has a configuration including a bellows portion 80, a link mechanism composed of a plurality of link members and joints, and a drive mechanism such as an air cylinder that drives in the vertical direction. Examples include: A link mechanism is a mechanical element in which a plurality of combined link members move relative to each other and convert an input motion into a different motion. Since the first suction part 11 and the second suction part 12 have the bellows part 80, a link mechanism, and a driving mechanism in the vertical direction, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 This makes it easier to switch the orientation of the suction part to different orientations in the suction process and the suction part moving process.

Above all, as shown in FIGS. 1 to 3, it is preferable that the first suction part 11 and the second suction part 12 have a bellows part 80. Since the first suction section 11 and the second suction section 12 each have the bellows part 80, the orientation of the suction surface 21 of the first suction section 11 and the suction surface 22 of the second suction section 12 can be easily changed. Can be done. 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 with respect to the upper surface part 41 of the mounting table 40, and in the suction part moving process, the suction surface 21 of the first suction part 11 and the suction surface 22 of the second suction part 12 are The suction surface 21 of the second suction section 12 can be tilted toward the second suction section 12, and the suction surface 22 of the second suction section 12 can be tilted toward the first suction section 11. In addition, since the first suction section 11 and the second suction section 12 each have the bellows part 80, the orientations of the suction surface 21 of the first suction section 11 and the suction surface 22 of the second suction section 12 are repeatedly changed. It also has the effect that the first suction section 11 and the second suction section 12 are less likely to be damaged even if the first suction section 11 and the second suction section 12 are damaged.

As shown in FIGS. 1 to 3, the conveying device 1 further includes a contact part 90 that contacts the conveyed object 100, and in the suction part moving process, the contact part 90 is moved to the first suction part 11 and the first suction part 11. It is preferable that the two suction parts 12 contact the conveyed object 100 that is being suctioned. In the suction part moving step, by bringing the contact part 90 into contact with the conveyed object 100 that is being adsorbed by the first suction part 11 and the second suction part 12, the movement of the first suction part 11 and the second suction part 12 causes If other objects are attached to the lifted object 100 due to static electricity or the like, the attached object can be released and dropped by contact with the contact portion 90, and the objects 100 to be transferred can be removed one by one. The first suction section 11 and the second suction section 12 facilitate transport.

Examples of the shape of the contact portion 90 include a rod shape, a plate shape, and a claw shape. Among these, it is preferable that the contact portion 90 has a claw-like shape. Since the contact portion 90 has a claw-like shape, the contact portion 90 easily comes into contact with the end of the conveyed object 100 that is attracted by the first suction portion 11 and the second suction portion 12, and the conveyed object is easily removed by static electricity or the like.
