[0006] To solve the above problems, a sheet for assembling a drive component according to one aspect of the present invention is a single sheet comprising: a drive forming portion for forming a drive part of a drive component; an actuation forming portion for forming an actuation part of a drive component that acts in accordance with the mechanical action of the drive part; and a cut portion, wherein the drive forming portion includes a drive engagement portion configured to engage with the cut portion, the actuation forming portion includes an actuation engagement portion configured to engage with the cut portion, the drive part is formed by the drive engagement portion engaging with the cut portion, and the actuation part is formed by the actuation engagement portion engaging with the cut portion, the sheet for assembling a drive component.

[Figure 11] This is a diagram showing the drive components related to the third modified example. [Modes for carrying out the invention]

[0013] [Embodiment] Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements will be denoted by the same reference numerals, and redundant explanations will be omitted as appropriate. Furthermore, the configurations described below are illustrative and do not limit the scope of the present invention in any way.

[0014] In addition, in this specification and the drawings, when distinguishing multiple components having substantially the same functional configuration, different alphabets may be appended after the same reference numeral. However, when there is no need to particularly distinguish each of the multiple components having substantially the same functional configuration, only the same reference numeral is appended to each of the multiple components. For example, when not particularly distinguishing each of the drive components 20a and 20b, they are simply referred to as "drive component 20".

[0015] FIG. 1 is a diagram showing a drive system 1 according to an embodiment of the present invention. As shown in FIG. 1, the drive system 1 according to this embodiment includes a power transmission unit 10 and two drive components 20a, 20b. In this embodiment, an example where the drive system 1 functions as a robot hand capable of grasping and carrying various objects will be described. Note that the drive system 1 according to this embodiment includes two drive components 20a and 20b, but the number of drive components is not limited to this, and it may be one, or three or more.

[0016] The power transmission unit 10 is configured to transmit power to the drive components 20a, 20b. The power transmission unit 10 mainly includes an actuator 100, a support shaft 102, a support member 104, a movable shaft 110, a connecting member 111, movable members 116, 118, and rotating members 124, 126.

[0017] The actuator 100 controls the movement of the movable shaft 110 in the axial direction. The actuator 100 may, for example, push out or pull in the movable shaft 110. The actuator 100 may be a known device such as a pneumatic actuator, an electric actuator, and a hydraulic actuator.

[0018] The movable shaft 110 has one end connected to the actuator 100 and the other end connected to the connecting member 111. The connecting member 111 extends perpendicularly to the movable shaft 110 and can move in the axial direction of the movable shaft 110 in conjunction with it. A movable member 116 is rotatably connected to one end of the connecting member 111, and a movable member 118 is rotatably connected to the other end.

[0019] The support shaft 102 is fixed at one end to the actuator 100 and at the other end to the support member 104. The support member 104 extends in a direction perpendicular to the axial direction of the support shaft 102, with a rotating member 124 rotatably connected to one end and a rotating member 126 rotatably connected to the other end.

[0020] The movable member 116 and the rotating member 124 are rotatably connected to each other, and the movable member 118 and the rotating member 126 are rotatably connected to each other. Connection parts 130 and 132 are provided at both ends of the rotating member 124 for connection to the drive component 20a. Connection parts 134 and 136 are provided at both ends of the rotating member 126 for connection to the drive component 20b.

[0021] The drive component 20a comprises a drive unit 200 and an operating unit 220. The drive unit 200 and the operating unit 220 are connected to each other via a connecting unit 210. Since the drive component 20b has substantially the same configuration as the drive component 20a, a detailed explanation is omitted here.

[0022] The drive unit 200 according to this embodiment is connected to the power transmission unit 10 and applies a mechanical force to the actuation unit 220 while deforming in accordance with the power from the power transmission unit 10. The drive unit 200 mainly has a connection surface 202, an upper surface 204, a lower surface 206, and a front surface 208.

[0023] One end of the connecting surface 202 is connected to a connecting portion 130 provided on one end of the rotating member 124, and the other end of the connecting surface 202 is connected to a connecting portion 132 provided on the other end of the rotating member 124. In this embodiment, the portion of the connecting surface 202 connected to the connecting portion 130 constitutes the point of application 203, and the portion of the connecting surface 202 connected to the connecting portion 132 constitutes the pivot point 205.

[0024] The actuation unit 220 operates in response to the mechanical action of the drive unit 200. The actuation unit 220 according to this embodiment has an operating surface 222, an upper surface 224, and a lower surface 226. In Figure 1, the front surface 208 of the drive unit 200 and the operating surface 222 of the actuation unit 220 are separated from each other, but the operating surface 222 and the front surface 208 may be in contact with each other in whole or in part.

[0025] Figure 2 shows the state of the drive system 1 when it grasps an object. When the movable shaft 110 is pushed out from the actuator 100, the connecting member 111 and the movable members 116 and 118 move away from the actuator 100 accordingly. At this time, the support member 104 does not move, and the rotating members 124 and 126 rotate around the part where they are connected to the support member 104.

[0026] As the rotating member 124 rotates, the connecting surface 202 of the drive unit 200 of the drive component 20a rotates in conjunction with it, around the pivot point 205. As a result, the upper surface 204 pushes against the front surface 208, and the front surface 208 comes into contact with the working surface 222 of the operating unit 220, applying force to the front surface 208.

[0027] The working surface 222 receives a mechanical force from the front surface 208, causing the upper surface 224 and lower surface 226 to deform and move toward the drive component 20b. At this time, the drive component 20b operates similarly to the drive component 20a, and as a result, as shown in Figure 2, the drive components 20a and 20b operate in a gripping motion.

[0028] Figure 3 is a perspective view of the drive component 20 according to this embodiment. The drive component 20 according to this embodiment is composed of a single sheet, and the drive unit 200 and the operating unit 220 are connected at the connecting unit 210. A slit 212 is formed in the sheet that constitutes the drive component 20. The drive unit 200 is formed when the tip 209 of the front surface 208 of the drive unit 200 engages with the slit 212. The operating unit 220 is formed when the tip 229 of the working surface 222 engages with the slit 212.

[0029] Figure 4 is a perspective view of the power transmission unit 10 according to this embodiment. In Figure 4, components that are substantially the same as those shown in Figures 1 and 2 are denoted by the same reference numerals, and their descriptions are omitted as necessary. The connection parts 130, 132, 134, and 136 according to this embodiment are cylindrical and have slits 131, 133, 135, and 137. The drive unit 200 of the drive component 20a is connected to the connection parts 130 and 132 by being inserted into the slits 131 and 133. The drive unit of the drive component 20b is connected to the connection parts 134 and 136 by being inserted into the slits 135 and 137.

[0030] (Sheet for assembling drive components) Figure 5 shows a sheet 30 for assembling a drive component 20 according to one embodiment of the present invention. The sheet 30 according to this embodiment has a rectangular shape and mainly has a drive forming portion 300 for forming a drive unit 200 and an operation forming portion 320 for forming an operation unit 220, and a cut S2 (cut portion). A bent portion C is formed on the same line as the cut S2 by folding the sheet 30.

[0031] The drive forming section 300 has a connecting surface section 302 for forming the connecting surface 202 of the drive section 200, an upper surface section 304 for forming the upper surface 204 of the drive section 200, a lower surface section 306 for forming the lower surface 206 of the drive section 200, a front surface section 308 for forming the front surface 208 of the drive section 200, and a tip section 309 (drive engagement section) for forming the tip section 209 of the drive section 200. The drive forming section 300 is provided with three bent sections D, E, and F formed by folds in the width direction of the sheet 30. In addition, the tip section 309 has a cut S3 on the side opposite to the side where the cut S2 in the width direction of the sheet 30 is provided.

[0032] The actuation forming portion 320 has an action surface portion 322 for forming the action surface 222 of the actuation portion 220, an upper surface portion 324 for forming the upper surface 224 of the actuation portion 220, a lower surface portion 326 for forming the lower surface 226 of the actuation portion 220, and a tip portion 329 (actuation engagement portion) for forming the tip portion 229 of the actuation portion 220. The actuation forming portion 320 according to this embodiment is provided with two bent portions A and B formed by folds in the width direction of the sheet 30. In addition, the tip portion 329 is provided with a cut S1 on the side opposite to the side where a cut S2 in the width direction of the sheet 30 is provided.

[0033] The drive component 20 according to this embodiment is assembled by bending the sheet 30 at the bending portion and engaging the drive engagement portion and the actuation engagement portion with the cut portion provided in the sheet 30. Specifically, bending portions A and B are bent in a valley fold, and the tip portion 329 is engaged with the cut portion S1 so that the cut portion S1 interlocks with the cut portion S2. This forms the actuation portion 220. Bending portions D, E and F are bent in a valley fold, and the tip portion 309 is engaged with the cut portion S2 so that the cut portion S3 interlocks with the cut portion S2. This forms the drive component 200, and the drive component 20 shown in Figure 3 is completed.

[0034] According to the sheet 30 of this embodiment, an underacted manipulator (such as an underacted robot hand) with enveloping characteristics similar to a two-jointed finger can be created simply by folding it at five bending points and engaging the parts together at three cuts. Therefore, it is possible to assemble a robot hand easily in a short time (for example, in about ten seconds). An underacted manipulator is a manipulator in which the number of movable joints is greater than the number of inputs, such as a closed linkage mechanism.

[0035] The drive component 20 using the sheet 30 according to this embodiment can be used as a disposable robot hand that can be discarded if it becomes dirty or deteriorated during use. Therefore, if oil or other contaminants adhere to the drive component 20 when it grasps food or the like, it can be replaced with a new drive component 20, eliminating the need to spend time cleaning the robot hand in the manufacturing plant.

[0036] Furthermore, the sheet 30 according to this embodiment provides a strong drive component 20, and prevents fragments from being generated from the drive component 20 during use. In addition, the drive component 20 according to this embodiment does not require adhesive to be used to bond the sheet 30. Therefore, for example, when handling food, adhesive will not adhere to the food.

[0037] Furthermore, since the sheet 30 according to this embodiment can be made of a soft material such as paper, the drive component 20 can gently grip food and other items. In addition, the drive component 20 does not damage objects (such as floors or tableware) even when it comes into contact with them, thus ensuring high safety. Moreover, since the sheet 30 can be made of inexpensive materials such as paper, the drive component 20 can be prepared at a low cost.

[0038] Furthermore, the drive component 20 according to this embodiment can be driven by a simple operation of supporting the fulcrum 205 while applying force to the point of application 203. In addition, because the distance from the area where force is applied to the area that contacts the object when gripping is short, it is possible to grip the object more strongly.

[0039] The drive component 20 described in this embodiment can be used in various fields. For example, the drive component 20 can be used for handling food transported on a conveyor belt in food processing plants, handling hazardous used waste in medical settings, and for the safe handling of living organisms (such as the human body).

[0040] (Food gripping experiment) To evaluate the performance of the robot hand configured with the drive system 1 described above, grasping experiments were conducted on various foods. Specifically, as shown in Figure 6, the ability to grasp food 40 by sandwiching it between the left and right drive components 20a and 20b was evaluated. For the material of the drive component 20 (paper strip hand), thick cardboard laminated with PE (polyethylene), which is commonly used for paper cups and the like, was used.

[0041] Furthermore, as shown in Figure 5, sheet 30, was formed in the cardboard with bends and cuts. The cardboard was designed with the following dimensions in the length direction: total length 240 mm, AB section 35 mm, LA section 20 mm, L-S1 section 5 mm, BC section 30 mm, BD section 80 mm, DE section 25 mm, EF section 60 mm, FR section 20 mm, and S3-R section 5 mm. The width of the cardboard was set to 30 mm. In addition, to accommodate differences in food size, smaller drive components 20 with reduced lengths of CD section and EF section to 6 / 7 and 5 / 6 respectively were prepared and compared. The food items to be gripped were selected to allow for handling in a standardized manner in a small-scale food factory, considering the intended use. The weight, shape, and condition of the food items used are shown in Table 1.

[0042] [Table 1]

[0043] Table 2 shows the results of food gripping. ◎ indicates a stable enveloping grip, ○ indicates lifting by pinching with the tip without enveloping, △ indicates lifting in an unstable state, and × indicates failure to lift. The notations 1 / 1, 6 / 7, and 5 / 6 represent the reduction ratio of the CD and EF sections.

[0044] [Table 2]

[0045] For items smaller than the size of the finger section (drive component 20), such as croissants and fried chicken, stable enveloping gripping was achieved. On the other hand, for relatively angular shapes such as omelets, the finger section could not be slid under the food, and it was lifted by pinching. Also, the opening and closing width of the robot hand was insufficient for fried chicken, so enveloping gripping was not possible. When gripping heavy savory bread, the contact area of ​​the robot hand was the largest, but because the radius was large and the angle when the robot hand was closed was small, excessive force was applied to the finger section, causing it to break. Only with the 5 / 6 size was stable gripping of a large omelet possible, although not by enveloping gripping. This can be attributed to the larger contact area of ​​the finger section of the 5 / 6 size compared to the other sizes. From the above, it was found that this robot hand can perform enveloping gripping as long as (1) the size does not significantly exceed the size of the finger section, and (2) the tip can be slid under the food.

[0046] The food gripping experiments described above revealed that because the shape directly replicates the gripping links of finger joints using the flexible material of paper, it is possible to grip food with a soft touch similar to that of a hand.

[0047] (Measurement of gripping force and load capacity) To evaluate the capabilities of this robot hand, gripping force and payload capacity were measured. As shown in Figure 7, the gripping force was measured by attaching a load cell to a cylindrical member 42 with a diameter of 50 mm and gripping it from the side with the robot hand. An air cylinder was used as the actuator 100. In order to confirm the relationship between the air pressure of the air cylinder and the gripping force, the air pressure was measured in 0.05 MPa increments from 0.05 MPa to 0.40 MPa. The measurement results of the gripping force are shown in Table 3.

[0048] [Table 3]

[0049] Furthermore, as shown in Figure 8, the payload capacity was determined by placing weights 46 (80, 90, 100, 110 g) inside a paper cup 44, lifting the paper cup 44 by gripping it from the side, and visually observing the maximum mass at which the paper cup 44 did not slip downwards. When the payload capacity was exceeded, slippage was clearly observed visually. Here, the air pressure during the measurement of the payload capacity was also measured in 0.05 MPa increments from 0.05 MPa to 0.40 MPa, similar to the measurement of gripping force. The measurement results of the payload capacity are shown in Table 4. As a criterion for judgment, "○" indicates that the paper cup could be gripped without slipping when lifted, "△" indicates that it could be gripped with slight slippage, and "×" indicates that it could not be gripped.

[0050] [Table 4]

[0051] The gripping force remained almost constant at 3.4-3.6 N regardless of the air pressure, as shown in Table 3. The payload capacity was 90 g, as shown in Table 4, and no change in payload capacity was observed even when the air pressure was increased or decreased. The validity of this payload capacity was confirmed by first deriving the coefficient of friction of paper by referring to JIS P8147 and calculating the frictional force. These results demonstrate the characteristic of a robot hand that applies a constant gripping force.

[0052] (Strength enhancement experiment) To improve the strength of the finger section, we attempted to create a robot hand using a pseudo-thick paper by assembling multiple sheets of paper, and tested its effectiveness. For the construction of the finger section, we used paper from a paper container with a thickness of approximately 0.3 mm. In this experiment, we constructed finger sections with one, two, three, and four layers of paper, and measured the gripping force in the same manner as in the aforementioned gripping force measurement experiment. The results are shown in Table 5.

[0053] [Table 5]

[0054] Table 5 shows that the gripping force increased with each layer of paper. This is thought to be because the increased strength of the finger section increased the proportion of thrust transmission to the air cylinder. Furthermore, focusing on the relationship between air pressure and gripping force, with one layer of paper, the gripping force remained almost constant even when the air pressure was increased, showing no change. However, with 2 to 4 layers of paper, increasing the pressure from 0.05 MPa to 0.10 MPa increased the gripping force, and thereafter, the gripping force showed almost no change. From these results, it can be said that the gripping force of this robot hand can be improved by increasing the strength, such as by increasing the thickness of the paper in the finger section, and that the gripping force can be controlled by increasing the strength to a certain level.

[0055] Next, the payload capacity of the four-layered robot hand was measured in the same manner as in the aforementioned payload capacity measurement experiment. The results are shown in Table 6.

[0056] [Table 6]

[0057] Table 6 confirms that, similar to the measurement of gripping force, the load capacity increases with increasing air pressure. While Table 5 shows no significant difference in gripping force between 0.10 MPa and 0.15 MPa, comparing the load capacity results for 0.10 MPa and 0.15 MPa in Table 6 reveals an increase from 160g at 0.10 MPa to 170g at 0.15 MPa. This is thought to be due to the finger portion moving to wrap around the gripped object when pressurizing from 0.05 MPa to 0.15 MPa, increasing the contact area. On the other hand, even when pressurizing from 0.15 MPa to 0.20 MPa, the finger portion does not move any further, resulting in no change in contact area and therefore no change in load capacity. Even when pressurizing above 0.20 MPa, the finger portion did not wrap around, and the load capacity remained constant.

[0058] Based on these results, we believe that if the strength can be increased by layering paper to make it thicker, then the gripping force can be controlled by air pressure. Furthermore, it was found that this robot hand not only increases the gripping force by increasing the air pressure, but also increases the contact area, thus increasing the payload capacity.

[0059] (First variation) Figure 9 shows a drive component 50 according to the first modified example. Unlike the drive component 20 shown in Figure 3, the drive component 50 according to the first modified example has a recess 510 formed such that the tip 509 of the drive unit 500 and the tip 526 of the operating unit 520 are located inside. The recess 510 is formed by a recess-forming surface 504 formed by providing a bent portion 508 on the lower surface 502 of the drive unit 500 and a recess-forming surface 524 formed by providing a bent portion 528 on the lower surface 522 of the operating unit 520.

[0060] According to the first modified example of the drive component 50, since the tip portions 509 and 526 are located in the recess 510, when using the drive component 50 to grasp an object (for example, food), it is suppressed that the tip portions 509 and 526 will come into contact with the object and cause damage.

[0061] (Second variation) Figure 10 shows a drive component 60 according to a second modified example. The drive component 60 according to the second modified example has increased strength by providing bent portions on the drive unit 600 and the operating unit 620. Specifically, two cuts are made in the width direction on the upper surface 602 of the drive unit 600, and a bent portion 604 is formed by bending upward between these cuts. Similarly, a bent portion 606 is formed on the opposite side in the width direction. This increases the strength of the upper surface 602. In addition, bent portions 610 and 612 are formed on the lower surface 608, thereby increasing the strength of the lower surface 608.

[0062] Furthermore, bent portions 624 and 626 are formed on the upper surface 622 of the operating portion 620, thereby increasing the strength of the upper surface 622. Alternatively, a fold may be formed on the lower surface 628 of the operating portion 620. This would increase the strength of the lower surface 628.

[0063] (Third variation) Figure 11 shows a drive component 70 according to the third modified example. As shown in Figure 11(a), the drive component 70 according to the third modified example is constructed by bending its front end so that it is rounded like a spoon. Specifically, as shown in Figure 11(b), the operating part 720 is bent at straight folds 732 and 734 extending from the center of its tip 731 to the side, thereby forming bent portions 736 and 738. The presence of bent portions 736 and 738 in the operating part 720 according to the third modified example provides the effect of preventing objects from spilling out from the side.

[0064] [supplement] The present invention has been described above based on embodiments. These embodiments are illustrative, and it will be understood by those skilled in the art that various modifications are possible in combinations of these components and processing processes, and that such modifications also fall within the scope of the present invention.

[0065] In the above embodiment, an example was described in which the slit portion has one slit, and the drive engaging portion and the actuating engaging portion engage with the same slit to form the drive portion 200 and the actuating portion 220. However, the slit portion is not limited to this and may have multiple slits. For example, the slit portion may have two slits provided at positions spaced apart from each other, with the drive engaging portion engaging with one slit and the actuating engaging portion engaging with the other slit. In this way, by having the drive engaging portion and the actuating engaging portion engage with different slits, interference between the respective engaging portions is suppressed, and simpler assembly becomes possible.

[0066] Furthermore, the mechanism for driving the drive component 20 is not limited to the power transmission unit 10 described in the above embodiment. For example, the connection surface 202 may be sandwiched between two plates that are joined together, and rotation of these plates may provide rotational torque to the connection surface 202.
