Description

[Technical Field]

[0001] The present disclosure relates to an opening determination system, an opening determination method, and a program. [Background technology]

[0002] In recent years, robots have been introduced in various fields, and tasks have been automated. For example, when inspecting products in a warehouse, there is a task of removing products from boxes, but there is a demand for a robot to determine whether the box has been opened before that. For example, if a box is sealed with tape and the tape is cut with a cutter to open the box, it is required that the robot automatically detect the opening by cutting the tape.

[0003] Here, one method for detecting whether a tape has been opened is disclosed in Patent Document 1. In Patent Document 1, the tape includes an electrical circuit, and when the tape is peeled off after being attached to an adherend, the electrical circuit is disconnected. Therefore, by detecting the electrical connection status of the electrical circuit, it is possible to determine whether the tape has been opened. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-7245 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the technology described in Patent Document 1, even if the tape is cut, it is possible that the electrical circuit may still be in contact at the cut point. In this case, the electrical connection of the contacting electrical circuit may be detected, which may result in a false determination that the box is unopened. As a result, the problem arises that it is not possible to accurately determine whether the box has been opened.

DETAILED DESCRIPTION OF THE INVENTION

[0013] <Embodiment 1> A first embodiment of the present disclosure will be described with reference to Fig. 1 to Fig. 5. Fig. 1 and Fig. 2 are diagrams for explaining the configuration of the opening detection system, and Fig. 3 to Fig. 5 are diagrams for explaining the operation of the opening detection system.

[0014] [composition] 1, the opening detection system in this embodiment is used to determine whether or not a box 10 sealed with tape 20 has been opened. The opening detection system includes tape 20 attached to the sealed portion of box 10, a robot hand 30 that moves sealed members 11 and 12 of box 10, and a detection device 40 that determines whether box 10 has been opened. Each component will be described below.

[0015] Box 10 is formed, for example, from a paper material having a predetermined strength, and is formed, for example, in a substantially rectangular parallelepiped shape. In this embodiment, box 10 has a storage compartment surrounded by a bottom surface and side surfaces for storing items, and the top surface is formed as lid member 11. In this case, one edge of lid member 11 is connected to the upper end of one side surface (the side surface on the rear side in FIG. 1 ) so that it can be opened and closed relative to the opening surface of the storage compartment, and the edge on the opposite side (the front side in FIG. 1 ) serves as a rotation end. When box 10 closes and seals the opening surface of the storage compartment, by blocking the opening surface with lid member 11, the edge serving as the rotation end of lid member 11 abuts against the edge located at the upper end of side surface member 12 located on the front side of the side surfaces shown in FIG. 1 , and tape 20 is attached to this abutting point as a sealing point P. In this way, the tape 20 is attached across the sealing area P located between the cover member 11 (one of the members to be sealed) and the side member 12 (the other member to be sealed).

[0016] The box body 10 may have any shape. Furthermore, the sealing point P is not necessarily limited to being located between the cover member 11 and the side member 12, but may be located between the two members (sealed members) that form the box body 10.

[0017] The tape 20 described above is configured to include a conductive member 21. The conductive member 21 is formed, for example, by printing a conductive wire or metal, and is exposed on the surface of the tape 20. The conductive member 21 is formed to extend in the longitudinal direction of the tape 20. In the example of FIG. 1 , the conductive member 21 is formed to extend from the lid member 11 to the side member 12 across the sealing area P, similar to the tape 20. Therefore, when the sealing area P is sealed, the conductive member 21 of the tape 20 is in a state of electrical continuity between the lid member 11 side and the side member 12 side, which are located on both sides of the sealing area P. On the other hand, when the tape 20 is cut at the sealing area P with a cutter or the like and the box 10 is opened, the conductive member 21 is in a state of electrical continuity between the lid member 11 side and the side member 12 side, which are located on both sides of the sealing area P.

[0018] The robot hand 30 (movement unit, measurement unit) is a device used to determine whether the box 10 has been opened, and includes a configuration for moving the lid member 11 of the box 10 from the sealing location P and a configuration for measuring the electrical characteristics of the conductive member 21 of the tape 20. Specifically, the robot hand 30 includes two operating units 31 and 33 that extend in two directions. The directions in which the two operating units 31 and 33 branch and extend may be, for example, perpendicular to each other or at any angle. As shown in FIG. 3 , these two operating units 31 and 33 are configured to be able to abut against the lid member 11 and the side member 12, respectively, and in particular, are configured to abut against the tape 20 attached to the lid member 11 and the side member 12 across the sealing location P.

[0019] One of the operation units 31 contacts the lid member 11 and has a holding unit 32 on its inner surface. The holding unit 32 can suck and hold the contacted lid member 11 by, for example, generating a suction force using a suction pump mounted inside the robot hand 30. Therefore, as shown in the left diagram of FIG. 3, the holding unit 32 of one of the operation units 31 of the robot hand 30 is brought into contact with the lid member 11 of the box body, and the robot hand 30 is moved upward as indicated by arrow F in the right diagram of FIG. 3, thereby moving the lid member 11 held by suction upward. At this time, if the tape 20 is cut at the sealing portion P, as shown in the left and right diagrams of FIG. 4, the lid member 11 can be separated from the side member 12 at the sealing portion P, i.e., the lid member 11 can be pulled and moved upward to open the sealing portion P (see arrow F in FIG. 4).

[0020] However, the holding portion 32 is not limited to holding the lid member 11 by suction, and may hold it in any manner. For example, the holding portion 32 may be made of an adhesive material and hold the lid member 11 by adhesive force. Alternatively, the holding portion 32 may have a gripping structure that is movable to grip the lid member 11, and may grip and hold the edge portion of the lid member 11 that forms the sealing portion P.

[0021] Furthermore, the holding portion 32 of one operation portion 31 also functions as the electrode portion 32. As a result, when the holding portion 32 of one operation portion 31 abuts against the tape 20 attached to the cover member 11, the electrode portion 32 which is the holding portion 32 also abuts against the conductive member 21. Note that the holding portion 32 and the electrode portion 32 may be provided as separate components on the inner surface side of one operation portion 31.

[0022] The other operation section 33 abuts against the side surface member 12 and has an electrode section 34 on its inner surface. As a result, when the other operation section 33 abuts against the tape 20 attached to the side surface member 12, the electrode section 34 also abuts against the conductive member 21.

[0023] The robot hand 30 then measures the electrical characteristics of the conductive member 21 in contact with the electrodes 32, 34 provided on one and the other operation units 31, 33, and notifies the determination device 40 of the measurement values. Specifically, the robot hand 30 measures the electrical characteristics between the conductive member 21 on the cover member 11 side that is in contact with the electrode 32 of one operation unit 31 and the conductive member 21 on the side of the side member 12 that is in contact with the electrode 34 of the other operation unit 33. In other words, the robot hand 30 measures the electrical characteristics between two points, that is, between the electrodes 32, 34 that are in contact with the conductive members 21 located on both sides of the sealing area P, on the cover member 11 side and the side member 12 side. At this time, the electrical characteristics of the conductive member 21 that are measured include, for example, whether or not there is continuity between the two points of the electrodes 32, 34, such as the resistance value between the two points or the impedance between the two points.

[0024] The measurement of the electrical characteristics of the conductive member 21 by the robot hand 30 is performed after the operation of moving the lid member 11 has been performed as described above. The operation of moving the lid member 11 upward by the robot hand 30 and the measurement of the electrical characteristics of the conductive member 21 may be performed manually by an operator or automatically in response to a command from the discrimination device 40. When performed manually, the operator first grasps the robot hand 30 and moves one operation unit 31 to contact the tape 20 on the lid member 11 and the other lid member 33 to contact the tape 20 on the side member 12, as shown in the left diagram of FIG. 3 . The operator then operates the holding unit 32 of the robot hand 30 to suction-hold the lid member 11, and moves the holding unit 32 upward while holding the lid member 11 by suction. If the tape 20 is cut at the sealing location P, the lid member 11 will move upward away from the side member 12 at the sealing location P, as shown in the right diagrams of FIG. 3 and 4 . Then, an operator performs a measurement operation to measure the electrical characteristics of the conductive member 21 between the electrode units 32 and 34. When the measurement is performed automatically, the robot hand 30 is configured to be drivable by some kind of drive device, and is moved by the drive device in response to a command from the discrimination device 40 so that one operation unit 31 contacts the tape 20 on the lid member 11 and the other lid member 33 contacts the tape 20 on the side member 12, as shown in the left diagram of FIG. 3 . Then, in response to a command from the discrimination device 40, the robot hand 30 holds the lid member 11 by suction with the holder 32, and in this state, is moved by the drive device to be pulled upward. Then, while holding and pulling the lid member 11 upward, the robot hand 30 measures the electrical characteristics of the conductive member 21 between the electrode units 32 and 34 in response to a command from the discrimination device 40. The robot hand 30 may be configured so that only one operation unit 31 moves upward, either manually by the operator or in response to a command from the discrimination device 40.

[0025] The discrimination device 40 is configured with one or more information processing devices each including a calculation device and a storage device. As shown in FIG. 2, the discrimination device 40 includes a measurement unit 41, a discrimination unit 42, and an output unit 43. The functions of the measurement unit 41, the discrimination unit 42, and the output unit 43 can be realized by the calculation device executing a program for realizing each function stored in the storage device. Each component of the discrimination device 40 will be described in detail below.

[0026] The measurement unit 41 acquires the electrical characteristics of the conductive member 21 between the electrode units 32, 34 measured by the robot hand 30 as described above. At this time, the measurement unit 41 may acquire the electrical characteristics of the conductive member 21 between the electrode units 32, 34 measured by the robot hand 30 manually operated by an operator. Alternatively, the measurement unit 41 may acquire such measured values ​​by automatically controlling the operation of the robot hand 30 according to a preset command, and measuring and controlling the electrical characteristics of the conductive member 21 between the electrode units 32, 34 while driving and controlling the cover member 11 to move upward as described above.

[0027] The discrimination unit 42 determines whether the box 10 has been opened, that is, whether the conductive member 21 of the tape 20 has been cut at the sealing location P, based on the measured electrical characteristics of the conductive member 21 between the electrode units 32, 34. For example, if the measured resistance value or impedance value between two points is lower than a threshold value close to 0, the discrimination unit 42 determines that the conductive member 21 is conductive and determines that the box 10 is unopened. On the other hand, if the measured resistance value or impedance value between two points is equal to or greater than the threshold value, the discrimination unit 42 determines that the conductive member 21 is cut and determines that the box 10 has been opened.

[0028] The output unit 43 outputs the determination result by the determination unit 42. For example, the output unit 43 outputs whether the box 10 is opened or unopened by displaying it on a display device. However, the output unit 43 may output whether the box 10 is opened or unopened by any method. For example, a specific sound may be output only when the box 10 is opened, or conversely, a specific sound may be output only when the box 10 is unopened.

[0029] [Operation] Next, the operation of the above-mentioned opening determination system will be described mainly with reference to the flowchart of FIG.

[0030] First, as shown in the left diagram of FIG. 3, the robot hand 30 is pressed against the box 10. Specifically, the robot hand 30 is moved so that the holding portion / electrode portion 32 of one operation portion 31 abuts against the tape 20 on the lid member 11 side, and the electrode portion 34 of the other operation portion 33 abuts against the tape 20 on the side member 12 side. Then, as shown by arrow F in the right diagram of FIG. 3, the robot hand 30 is moved upward. At this time, the holding portion 32 of one operation portion 31 of the robot hand 30 moves upward while sucking the lid member 11, thereby moving the lid member 11 held by suction upward (step S1).

[0031] Next, the electrode units 32, 34 provided on one and the other operation units 31, 33 of the robot hand 30 measure the electrical characteristics of the conductive member 21 in contact therewith, and notify the measurement value to the discrimination device 40 (step S2). Note that the above-mentioned operation of the robot hand 30 may be performed manually by an operator, or may be performed automatically in response to a command from the discrimination device 40.

[0032] Next, the discrimination device 40 checks whether the conductive member 21 is conductive based on the measured value of the electrical characteristics of the conductive member 21 between the electrode portions 32, 34 (step S3). If the conductive member 21 is conductive (Yes in step S3), the discrimination device 40 determines that the box 10 is unopened (step S5). On the other hand, if the conductive member 21 is not conductive (No in step S3), the discrimination device 40 determines that the box 10 has been opened (step S4). Thereafter, the discrimination device 40 outputs a determination result indicating whether the box 10 has been opened (step S6).

[0033] As described above, in this embodiment, the electrical characteristics of the conductive member 21 of the tape 20 are measured in a state in which the robot hand 30 lifts the lid member 11 away from the side member 12 at the sealing portion P of the box 10. Therefore, when the tape 20 is cut, the electrical characteristics can be measured in a state in which the conductive member 21 of the tape 20 on the lid member 11 side and the conductive member 21 of the tape 20 on the side member 12 side are securely pulled apart, as shown in the right diagrams of Fig. 3 and 4. As a result, it is possible to accurately determine whether the box 10 sealed with tape has been opened.

[0034] <Embodiment 2> Next, a second embodiment of the present disclosure will be described with reference to Fig. 6 to Fig. 7. Fig. 6 is a block diagram showing the configuration of the opening determination system in the second embodiment, and Fig. 7 is a diagram for explaining the operation of the opening determination system. Note that in this embodiment, the configuration that is different from the opening determination system described in the first embodiment will be mainly described.

[0035] 6, in this embodiment, the box 10 is formed in the same manner as in the first embodiment, but the state in which the tape 20 is attached is different. Specifically, the tape 20 in this embodiment extends across the sealing area P located between the lid member 11 located on the top side and the side member 12, and is also attached by extending to the bottom surface of the box 10. In this case, the conductive member 21 included in the tape 20 extends from the lid member 11 of the box 10 through the side member 12 to the bottom surface.

[0036] In this embodiment, the mounting surface 50 (connecting member) on which the box body 10 is placed is formed of a conductive material. Therefore, when the bottom surface of the box body 10 is placed on the mounting surface 50, the conductive member 21 included in the tape 20 located on the bottom surface of the box body 10 comes into contact with the mounting surface 50, and the conductive member 21 and the mounting surface 50 are electrically connected. Furthermore, the mounting surface 50 is electrically connected to the robot hand 30 via wiring 51 (connecting member). For example, the wiring 51 is connected to a wiring electrode unit (not shown) provided on the robot hand 30. As a result, the conductive member 21 included in the tape 20 located on the bottom surface of the box body 10 that is in contact with the mounting surface 50 is electrically connected to the wiring electrode unit of the robot hand 30.

[0037] Furthermore, the robot hand 30 in this embodiment is equipped with one operating unit 31, similar to the first embodiment. The one operating unit 31, similar to the above, comes into contact with the lid member 11 and is equipped with a holding unit 32 and an electrode unit 32. Therefore, by moving the robot hand 30 upward as shown by arrow F in Fig. 7, the lid member 11 that is sucked and held by the holding unit 32 can be moved upward. However, the robot hand 30 in this embodiment does not have the other operating unit 33 shown in Fig. 1 etc.

[0038] Then, in a state in which the robot hand 30 in this embodiment has performed the operation of moving the lid member 11 as described above, it measures the electrical characteristics between the electrode unit 32 provided on one operation unit 31 and the wiring electrode unit connected to the above-mentioned wiring 51, and notifies the measurement value to the discrimination device 40. In other words, the robot hand 30 measures the electrical characteristics between the conductive member 21 on the lid member 11 side that is in contact with the electrode unit 32 of one operation unit 31, and the conductive member 21 on the bottom side of the box 10 that is in contact with the placement surface 50 that is further connected to the wiring 51 that is connected to the wiring electrode unit.

[0039] The movement of the lid member 11 and the measurement of the electrical characteristics by the robot hand 30 described above may be performed manually by an operator, or may be performed automatically in response to a command from the discrimination device 40.

[0040] In this embodiment, the discrimination device 40 acquires the electrical characteristics of the conductive member 21 measured by the robot hand 30 using the measurement unit 41. The discrimination unit 42 then determines whether the box 10 has been opened, i.e., whether the conductive member 21 of the tape 20 has been cut at the sealing location P, based on the measured electrical characteristics of the conductive member 21. Specifically, the discrimination unit 42 determines whether the box 10 has been opened by checking whether there is electrical continuity between the conductive member 21 on the lid member 11 side that abuts against the electrode unit 32 of one of the operation units 31 and the conductive member 21 on the bottom side of the box 10 that abuts against the mounting surface 50 that is further connected to the wiring 51 connected to the wiring electrode unit. For example, as shown in the right diagram of FIG. 7 , when the tape 20 is cut and the lid member 11 is separated from the side member 12 at the sealing location P, the conductive member 21 is not conductive, and the discrimination unit 42 determines that the box 10 has been opened. On the other hand, if the tape 20 is not cut, the conductive member 21 is conductive, and the discriminator 42 therefore determines that the box 10 is unopened.

[0041] Even with the opening detection system configured as described above, it is possible to accurately detect whether the box 10 sealed with the tape 20 has been opened.

[0042] <Embodiment 3> Next, a third embodiment of the present disclosure will be described with reference to Fig. 8 to Fig. 10. Fig. 8 is a block diagram showing the configuration of the opening detection system in the third embodiment, and Figs. 9 and 10 are diagrams for explaining the operation of the opening detection system. Note that in this embodiment, the configuration that is different from the opening detection systems described in the first and second embodiments will be mainly described.

[0043] As shown in FIG. 8, in this embodiment, the box 10 has a lid member 11 located on the top surface, which is separated at the center into two members, a first lid member 11a and a second lid member 11b. One edge of the first lid member 11a is connected to the upper end of one side surface (the side surface on the front side in FIG. 8), and the opposite edge is a rotation end. The second lid member 11b has one edge connected to the upper end of one side surface (the side surface on the back side in FIG. 8), and the opposite edge is a rotation end. The first lid member 11a and the second lid member 11b abut against each other near the center of the top surface, with the rotation ends butting against each other, and the abutting point serves as a sealing point P, to which the tape 20 is attached. In this way, the tape 20 is attached to the sealing point P located between the first lid member 11a and the second lid member 11b, straddling the sealing point P.

[0044] Similarly to the first embodiment, the robot hand 30 in this embodiment includes one operation unit 31 that contacts the cover member 11. However, the one operation unit 31 in this embodiment is longer than that in the above-described embodiment, and includes a first electrode unit 32' at the tip end and a second electrode unit 34' at the base end, spaced apart from the first electrode unit 32'. Specifically, the first electrode unit 32' contacts the tape 20 located on the first cover member 11a side, and the second electrode unit 34' contacts the tape 20 located on the second cover member 11b side. The robot hand 30 in this embodiment does not include the other operation unit 33 shown in FIG. 1 and other figures.

[0045] In this embodiment, as shown in the left diagram of Fig. 9, with the electrode units 32', 34' of the robot hand 30 in contact with the first cover member 11a and the second cover member 11b, respectively, the robot hand 30 is moved downward as indicated by arrow F in the right diagram of Fig. 9. As a result, the first cover member 11a and the second cover member 11b are each pressed downward, and when the tape 20 at the sealing portion P is cut, the first cover member 11a and the second cover member 11b are moved away from each other at the sealing portion P as shown in the right diagram of Fig. 10.

[0046] Furthermore, in the present embodiment, while the robot hand 30 has performed the operation of moving the first cover member 11a and the second cover member 11b as described above, it measures the electrical characteristics between the first electrode unit 32' and the second electrode unit 34' provided on one of the operation units 31, and notifies the determination device 40 of the measurement value. In other words, the robot hand 30 measures the electrical characteristics between the conductive member 21 on the first cover member 11a side that is in contact with the first electrode unit 32', and the conductive member 21 on the second cover member 11b side that is in contact with the second electrode unit 34'.

[0047] The movement of the lid member 11 and the measurement of the electrical characteristics by the robot hand 30 described above may be performed manually by an operator, or may be performed automatically in response to a command from the discrimination device 40.

[0048] In this embodiment, the discrimination device 40 acquires the electrical characteristics of the conductive member 21 measured by the robot hand 30 using the measuring unit 41. The discrimination unit 42 then determines whether the box 10 has been opened, i.e., whether the conductive member 21 of the tape 20 has been cut at the sealing location P, based on the measured electrical characteristics of the conductive member 21. Specifically, the discrimination unit 42 determines whether the box 10 has been opened by checking whether there is electrical continuity between the conductive member 21 on the first cover member 11a side abutting the first electrode portion 32′ and the conductive member 21 on the second cover member 11b side abutting the second electrode portion 34′. For example, as shown in the right diagrams of FIGS. 9 and 10, when the tape 20 is cut and the first cover member 11a and the second cover member 11b are separated at the sealing location P, the conductive member 21 is not electrically conductive, and the discrimination unit 42 determines that the box 10 has been opened. On the other hand, as shown in the left diagrams of Figures 9 and 10, if the tape 20 is not cut, the conductive member 21 is conductive, and the discrimination unit 42 determines that the box 10 is unopened.

[0049] Even with the opening detection system configured as described above, it is possible to accurately detect whether the box 10 sealed with the tape 20 has been opened.

[0050] <Embodiment 4> Next, a fourth embodiment of the present disclosure will be described with reference to Fig. 11. Fig. 11 is a diagram showing the configuration of an opening determination system according to the fourth embodiment. Note that this embodiment shows an outline of the configuration of the opening determination system described in the above-mentioned embodiments.

[0051] As shown in FIG. 11, the opening detection system in this embodiment includes: a tape 120 attached to a sealing portion P located between two sealed members 111 and 112 in the box body 100 and including a conductive member 121 extending across the sealing portion P; a moving unit 130 that moves at least one of the sealed members 111 and 112 from the sealing portion P; a measuring unit 140 that measures electrical characteristics of the conductive members 121 included in the tapes 120 located on both sides of the sealing portion P while the sealing target members 111 and 112 are being moved; Equipped with.
