[Modes for carrying out the invention]

[0008] The following describes one typical embodiment with reference to the drawings. The items classified in <> below can be used independently or in relation to each other.

[0009] [overview] <Adhesive Tape Application System> For example, an adhesive tape application system (e.g., adhesive tape application system 1) applies adhesive tape (e.g., adhesive tape TA) to the fixing surface of a cup (e.g., cup CU), which is a processing jig for eyeglass lenses, to the cup. For example, the adhesive tape application system comprises a base moving unit (e.g., adhesive tape supply device 300), a first moving unit (e.g., robot arm 100), a second moving unit (e.g., moving unit 230 of cup mounting device 200), and a control device (e.g., control device 600). For example, the adhesive tape application system comprises a cup mounting device (e.g., cup mounting device 200) for attaching a cup to an eyeglass lens.

[0010] <Cup mounting device> For example, the cup mounting device has a blocking arm (e.g., blocking arm 232) that holds the cup. For example, the cup mounting device attaches the cup to the refractive surface of the spectacle lens via adhesive tape by moving the blocking arm toward the spectacle lens placed in a predetermined position. For example, the cup mounting device includes a moving means (e.g., moving unit 230) for changing the relative positional relationship between the cup held by the blocking arm and the spectacle lens supported by the lens support mechanism. For example, the cup mounting device may include a lens information acquisition means (e.g., lens information acquisition unit 240) for obtaining information about the spectacle lens supported by the lens support mechanism (e.g., optical characteristics such as the optical center position of the spectacle lens and the direction of the astigmatism axis, positional information of markings on the spectacle lens, etc.).

[0011] <Base unit for moving> For example, the base movement unit moves a base (e.g., a base sheet 30) on which adhesive tape is adhered. For example, the base movement unit comprises a belt (e.g., a belt 316) on which the base is placed, and a drive source (e.g., a motor 318) for moving the belt in the feed direction. For example, the base movement unit may include a base guiding means (e.g., a base sheet guiding mechanism 320) that guides the movement of the base in a direction away from the plane on which the adhesive tape is installed. The base guiding means allows the adhesive tape to be easily peeled off the base by moving the base away from the plane on which the adhesive tape is installed in at least a perpendicular direction. For example, it is sufficient to have a component in a direction that is at least perpendicular to the plane on which the adhesive tape is installed. For example, it may be an oblique direction with a perpendicular component in the direction away.

[0012] <Adhesive properties of adhesive tape> For example, the adhesion of the substrate to the adhesive tape is weaker than, or the same as (including approximately the same as), the adhesion of the adhesive tape to the cup. If the adhesion of the substrate to the adhesive tape is weaker than the adhesion of the adhesive tape to the cup, when the adhesive tape is attached to the cup, the adhesive tape will detach from the substrate more smoothly while remaining attached to the cup. Even if the adhesion of the substrate to the adhesive tape and the cup is the same (including approximately the same as), if the substrate is given a trigger to move away from the adhesive tape, a shear force will act, and the substrate may gradually detach from the adhesive tape while the adhesive tape remains attached to the cup.

[0013] <First Mobile Unit> For example, the first moving unit moves a first holding unit (e.g., the holding part 137) that can hold a cup. For example, the first moving unit includes a robot arm. For example, the robot arm has an arm part (e.g., the arm part 130) having a plurality of joint parts (e.g., joint parts J1 to J6), and a holding part (e.g., the holding part 137) provided on the arm part for holding and releasing an object. And, for example, the robot arm moves the object held by the holding part by rotating the arm part via the joint parts. In this case, the holding part is used as the first holding unit.

[0014] <The second moving unit> For example, the second moving unit moves a second holding unit (e.g., the blocking arm 232) that can hold a cup. For example, the second holding unit is separate from the second moving unit, and the second moving unit is configured separately from the first moving unit. For example, the blocking arm included in the cup mounting device is used as the second holding unit. By using the blocking arm as the second holding unit, the attachment of the cup to the spectacle lens can be performed more efficiently. Note that the second holding unit may be used in combination with the first holding unit, and the second moving unit may be used in combination with the first moving unit. In this case, for example, the cup is held by the holding part of the robot arm, and the holding part is moved by the robot arm. By using a highly versatile robot arm as the second moving unit, the restrictions on the installation of the second moving unit are reduced.

[0015] <The control device> For example, the control device controls the base moving unit to move the base in a predetermined feed direction. For example, the control device controls the first moving unit to move the first holding unit. For example, the control device controls the first moving unit to hold an object (e.g., a cup) by the first holding unit. For example, the control device controls the second moving unit to move the second holding unit. For example, the control device controls the second moving unit to hold an object (e.g., a cup) by the second holding unit.

[0016] For example, the control device controls the substrate moving unit to move the substrate in a predetermined feeding direction, thereby moving the adhesive tape to the first position. For example, the control device controls the first moving unit to hold the cup with the first holding unit, and after the adhesive tape is moved to the first position, the control device moves the first holding unit while the cup is held, thereby attaching the cup onto the adhesive tape. For example, after the cup is attached onto the adhesive tape, the control device controls the second moving unit to hold the cup attached onto the adhesive tape with the second holding unit.

[0017] Then, for example, after the cup is held by the second holding unit, the control device controls at least one of the substrate moving unit and the second moving unit, moves at least one of the first holding unit and the second holding unit, and changes the positional relationship between the cup held by the second holding unit and the substrate, thereby detaching the adhesive tape attached to the cup from the substrate. Thereby, the adhesive tape can be automatically attached to the cup. Also, an economically inexpensive and compact system can be realized without complicating the configuration of the system.

[0018] Regarding the control for changing the positional relationship between the cup and the substrate, for example, the control device may control the substrate moving unit to move the substrate in a direction away from the cup held by the second holding unit. For example, the direction in which the substrate moves away from the cup may have at least a component in a direction perpendicular to the plane on which the adhesive tape attached to the cup is installed. For example, it may be a diagonal direction having a perpendicular component in the direction of separation. Alternatively, regarding the control for changing the positional relationship between the cup and the substrate, for example, the control device may control the second moving unit, move the second holding unit, and move the cup in a direction away from the substrate, thereby detaching the adhesive tape from the substrate. For example, the direction in which the cup moves away from the substrate may have at least a component in a direction perpendicular to the plane on which the adhesive tape is installed on the substrate. In this case, it may be a diagonal direction having a perpendicular component in the direction of separation.

[0019] Furthermore, for example, when detaching the adhesive tape from the base, the control device may control both the base movement unit and the second movement unit to move both the base and the second holding unit. For example, the control device may control both the base movement unit and the second movement unit to change the positional relationship between the cup and the base by moving the cup and the base held by the second holding unit in a direction away from each other. This allows the adhesive tape attached to the cup to be detached from the base more smoothly. Specifically, for example, the control device may control the second movement unit to move the cup in a direction along the plane on which the adhesive tape is installed, and at the same time control the base movement unit to move the base in a direction away from the plane on which the adhesive tape is installed in synchronization with the movement of the cup. For example, the direction away from the plane on which the adhesive tape is installed only needs to have a component that is at least perpendicular to the plane on which the adhesive tape is installed. For example, it may be an oblique direction with a perpendicular component to the direction of separation. In this case, for example, the control device may control the second movement unit to move the cup so that the base is gradually peeled off from the front in the direction along the plane on which the adhesive tape is installed. In this case, for example, synchronization between the movement of the cup and the movement of the base would simply mean that they move at the same time and at the same speed.

[0020] Furthermore, for example, if the base movement unit is equipped with base guide means, the control device may, after the cup is held by the second holding unit, control the base movement unit to move the base away from the plane on which the adhesive tape is installed by the base guide means, and simultaneously control the second movement unit in synchronization with this movement to move the second holding unit in a direction along the plane. In this case, for example, the synchronization of the movement of the base and the movement of the second holding unit only needs to be at the same timing as the movement of the cup by the second holding unit and the movement of the base, and the movement speeds of both are the same. This allows the adhesive tape attached to the cup to be detached from the base more smoothly.

[0021] For example, if the adhesive tape application system includes a cup attachment device, the first moving unit includes a robot arm, and the holding portion of the robot arm is used as the first and second holding units, the control device may control the robot arm to transport the cup held by the holding portion after the adhesive tape attached to the cup has detached from the base, and then attach the transported cup to the cup holding portion (e.g., mounting portion 231) of the blocking arm. This reduces the constraints on the positional relationship between the cup attachment device and the adhesive tape supply device, and increases the degree of freedom in their installation.

[0022] Furthermore, the control device may cooperate with the control means provided by each device or unit (for example, control units 139, 260, 360, 410, 510) to control the operation of each device or unit, or the control means of each device or unit may be included in the control device. Of course, the control device may be composed of multiple control means.

[0023] <Eyeglass Lens Processing System> For example, an eyeglass lens processing system (e.g., eyeglass lens processing system 2) includes, in addition to an adhesive tape application system, an eyeglass lens processing device (e.g., eyeglass lens processing device 400), a cup mounting device, and a robotic arm.

[0024] For example, the first holding unit uses the holding part of a robot arm, and the first moving unit uses a robot arm. Also, for example, the second holding unit uses the blocking arm of a cup mounting device, and the second moving unit uses a moving mechanism.

[0025] For example, the control device controls a robot arm to transport the spectacle lens placed in a predetermined position and install it in a predetermined lens mounting position on the cup mounting device. Alternatively, for example, the control device controls the robot arm to hold the cup placed in the predetermined position with the holding unit and attach the cup to the adhesive tape moved to the first position. For example, after the adhesive tape attached to the cup detaches from the base, the control device controls the moving means to move the blocking arm, thereby attaching the cup to the refractive surface of the spectacle lens placed in the predetermined position via the adhesive tape. After the cup is attached to the refractive surface of the spectacle lens, the control device controls the robot arm to hold the spectacle lens together with the cup held by the blocking arm with the holding unit, remove it, and attach it to the lens holding shaft of the spectacle lens processing device. After the processing of the spectacle lens is completed by the spectacle lens processing device, the control device controls the robot arm to hold the spectacle lens held on the lens holding shaft with the holding unit, remove it, and move the processed spectacle lens to a predetermined position. This allows for more appropriate processing with a compact spectacle lens processing system.

[0026] [Examples] One typical embodiment of this disclosure will be described with reference to the drawings. Figure 1 shows an adhesive tape application system 1 and an eyeglass lens processing system 2 according to the embodiment.

[0027] In Figure 1, the adhesive tape application system 1 includes a robot arm 100, a cup mounting device (blocker) 200, and an adhesive tape supply device 300. The spectacle lens processing system 2 includes these plus a spectacle lens processing device 400. The spectacle lens processing system 2 may also include a tray transport device 500 for transporting trays TR. A pair of unprocessed spectacle lenses (hereinafter referred to as lenses LE) are placed at predetermined positions on tray TR. Also, cups CU (see Figure 2), which are lens processing jigs, are placed at predetermined positions on tray TR. For example, cups CU are placed at predetermined positions for each of the left and right lenses LE. The processed lenses LE are then returned to tray TR.

[0028] <Cups and adhesive tape> Figure 2 illustrates the cup CU and adhesive tape TA. The cup CU is used as a processing jig for the lens LE. The adhesive tape TA is used to fix the cup CU to the refractive surface of the lens LE. The refractive surface of the lens LE to which the cup CU is fixed is generally the front surface of the lens, but it may also be the back surface.

[0029] In Figure 2, the cup CU of this embodiment comprises a base portion 10 and a flange portion 11. For example, the base portion 10 and the flange portion 11 are integrally formed from resin. The base portion 10 is inserted into a cup holder 430 (see Figure 3) provided on the lens holding shaft 402L of the spectacle lens processing device 400. A keyway 10b extending in the left-right direction is formed on the upper part of the base portion 10 shown in Figure 2. The keyway 10b is used to set the astigmatism axis angle of the lens LE and the left-right direction of the lens LE in a predetermined positional relationship when attaching the cup CU to the lens LE and when processing the periphery of the lens LE. In addition, a notch 10c is formed in the base portion 10, which serves as an example of an indicator for determining the vertical direction of the lens LE (here, the vertical direction when wearing spectacles).

[0030] The flange portion 11 is formed in an elliptical shape with a larger diameter than the base portion 10. The longitudinal direction of the elliptical shape is the same as the direction in which the keyway 10b extends. A recessed portion 11a is formed around the base portion 10 on the upper surface of the flange portion 11. The recessed portion 11a is used to reduce rotational misalignment when inserted into the cup holder 430. The tip of the cup holder 430 has a recessed portion (not shown) into which the recessed portion 11a formed on the flange portion 11 is fitted.

[0031] Furthermore, two hooks 12 are formed on both sides in the longitudinal direction of the upper surface of the flange portion 11. The hooks 12 are formed at a position away from the uneven portion 11a and in a position that does not interfere when the base portion 10 is inserted into the cup holder 430 and the mounting portion 231 (see Figure 5) of the cup mounting device 200. For example, the two hooks 12 are used as a member that the operator holds with their fingers when peeling off the cup CU attached to the lens LE via adhesive tape TA. The two hooks 12 may also be used when the holding portion 137 (see Figure 4) of the robot arm 100 holds the cup CU.

[0032] In Figure 2, the adhesive tape TA is formed to have the same (or approximately the same) outer shape as the lower surface of the flange portion 11. For example, the base material of the adhesive tape TA is rubber. Also, for example, the thickness of the adhesive tape TA is about 1 mm. Both sides (top and bottom) of the adhesive tape TA are configured to be adhesive. The top surface of the adhesive tape TA is attached to the fixing surface of the cup CU (i.e., the lower surface of the flange portion 11), and the bottom surface of the adhesive tape TA is attached to the refractive surface of the lens LE. In this way, the cup CU is fixed to the refractive surface of the lens LE via the adhesive tape TA.

[0033] The adhesive tape TA may also be provided with a tab 21a that protrudes in part from the outer circumference of the flange portion 11. For example, the tab 21a is integrally formed with the base material of the adhesive tape TA. The tab 21a is used when peeling the adhesive tape TA from the lens LE and the cup CU. By peeling the adhesive tape TA from the cup CU, the cup CU can be reused.

[0034] <Eyeglass lens processing equipment> Figure 3 is a diagram illustrating the schematic configuration of the eyeglass lens processing apparatus 400. The eyeglass lens processing apparatus 400 comprises a lens holding shaft 402 (lens holding shafts 402L, 402R) for holding the lens LE, a processing tool 460 for processing the periphery of the lens LE, a moving unit 450 for changing the relative positional relationship between the lens LE held by the lens holding shaft 402 and the processing tool 463, and a control unit 410 for controlling the moving unit 450. For example, the processing tool 460 is attached to the rotating shaft 461 and comprises at least one of a finishing tool 462 and a roughing tool 463 having V-grooves for forming a bevel.

[0035] The lens LE is held by a pair of lens retaining shafts 402L and 402R. A cup holder 430 is attached to one of the lens retaining shafts 402L, into which the base 10 of the cup CU, fixed to the lens LE, is inserted. The cup holder 430 has an insertion hole 431a in which a key 431b is formed. The key groove 10b formed in the base 10 of the cup CU is fitted into the key 431b, thereby maintaining a constant relationship between the astigmatism axis angle of the lens LE and the reference direction of the lens retaining shaft 430. After the cup CU is mounted on the cup holder 430, the lens retaining shaft 402R is moved toward the lens LE, and the lens LE is held in place by a lens retainer 435 attached to the lens retaining shaft 402R. In this way, the lens LE is held by the lens retaining shaft 402. The eyeglass lens processing apparatus 400 includes a lens holding mechanism 440 that moves the lens holding shaft 402R toward the lens holding shaft 402L, and the lens holding mechanism 440 is controlled by a control unit 410.

[0036] For example, a detailed configuration of the eyeglass lens processing apparatus 400 is described in Japanese Patent Publication No. 2013-158866.

[0037] <Robot Arm> Figure 4 illustrates an example of a robot arm 100. The robot arm 100 in this embodiment includes an arm section 130. The arm section 130 has multiple joints, and its posture can be changed by rotating each part via the joints. In detail, the arm section 130 of the robot arm 100 in this embodiment includes a base 131, a shoulder 132, a lower arm 133, a first upper arm 134, a second upper arm 135, a wrist 136, and a holding section 137. In Figure 4, the rotation axes X1 to X6 are shown by illustrating the direction around each axis.

[0038] The base 131 supports the entire arm portion 130. The shoulder 132 is connected to the upper part of the base 131 via a first joint J1. The shoulder 132 rotates relative to the base 131 about a rotation axis X1 that extends in a direction intersecting the base 140 (vertically in this embodiment). One end of the lower arm 133 is connected to a part of the shoulder 132 via a second joint J2. The lower arm 133 rotates relative to the shoulder 132 about a rotation axis X2 that extends horizontally. The first upper arm 134 is connected to the end of the lower arm 133 opposite to the side connected to the shoulder 132 via a third joint J3. The first upper arm 134 rotates relative to the lower arm 133 about a rotation axis X3 that extends horizontally. The second upper arm 135 is connected to the tip side (the side where the holding part 137 is provided) of the first upper arm 134 via the fourth joint J4. The second upper arm 135 rotates relative to the first upper arm 134 about the rotation axis X4. The wrist 136 is connected to the tip side of the second upper arm 135 via the fifth joint J5. The wrist 136 rotates relative to the second upper arm 135 about the rotation axis X5. The holding part 137 is connected to the tip side of the wrist 136 via the sixth joint J6. The holding part 137 rotates relative to the wrist 136 about the rotation axis X6.

[0039] For example, the holding part 137 has two fingers 137a. The two fingers 137a hold the object (cup CU, lens LE, etc.). The shape of the fingers 137a is not particularly limited as long as it can hold the object of the choice.

[0040] Furthermore, the arm section 130 contains motors for rotating each part around each of the rotation axes X1 to X6. In addition, the wrist 136 contains actuators for opening and closing the two fingers 137a.

[0041] The arm portion 130 is fixed to the base 140. In this embodiment, the base 140 is placed on a horizontal mounting surface. The base 140 is provided with an arm movement unit 141 that moves the arm portion 130 in a direction parallel to the mounting surface. When the arm movement unit 141 is driven, the entire arm portion 130 moves parallel to the mounting surface. The configuration of the arm movement unit 141 can be selected as appropriate. For example, the arm movement unit 141 may be equipped with wheels and a motor to rotate the wheels. Alternatively, a belt conveyor or the like may function as the arm movement unit. Furthermore, the base 140 (arm portion 130) may be fixed to the mounting surface. In this case, the mounting surface may be a wall or the like that extending in the vertical direction.

[0042] The robot arm 100 in this embodiment includes a control unit 139 that is responsible for various controls (for example, control of motors that rotate each part and actuators that drive the fingers 137a).

[0043] Furthermore, the robot arm 100 may be equipped with a detection unit (e.g., an encoder) for detecting the angles of each part of the arm 130 (for example, the angle of the shoulder 132 relative to the base 131, and the angle of the lower arm 133 relative to the shoulder 132). By detecting all the angles of each part of the arm 130 using the detection unit, the position of the holding part 137 provided at the tip of the arm 130 can be determined. Therefore, even if, for example, an operator manually adjusts the angles of each part of the arm 130 and moves the position of the holding part 137 to a desired position, the control unit 139 of the robot arm 100 can detect the position of the moved holding part 137 (for example, the position of the holding part 137 relative to the base 140). For detailed examples of the configuration of the robot arm, see, for example, Japanese Patent Application Publication No. 2021-58947 and Japanese Patent Application Publication No. 2019-141970.

[0044] <Cup mounting device> Figure 5 is a schematic diagram of the cup mounting device 200. The cup mounting device 200 is used to attach the cup CU to the refractive surface (e.g., the surface) of the lens LE.

[0045] The cup mounting device 200 attaches (fixes) the cup CU to the refractive surface of the lens LE via adhesive tape TA by relatively changing the position of the cup CU held by the blocking arm 232 and the lens LE supported by the lens support mechanism 210.

[0046] The blocking arm 232 includes a mounting portion 231 for holding the cup CU. The mounting portion 231 is attached to the tip of the blocking arm 232. The mounting portion 231 has an insertion hole 231a into which the base 10 of the cup CU is inserted.

[0047] The cup mounting device 200 includes a moving unit 230 that changes the relative positional relationship between the cup CU held by the blocking arm 232 and the lens LE supported by the lens support mechanism 210. In the embodiment, the moving unit 230 moves the blocking arm 232 toward the lens LE which is placed in a predetermined position (the lens support unit 210 in the embodiment), thereby fixing the cup CU mounted on the mounting part 231 to the refractive surface of the lens LE via adhesive tape TA. The moving unit 230 includes an X-direction moving unit 235, a Y-direction moving unit 236, and a Z-direction moving unit 237. The blocking arm 232 is held by an arm holding base 233. The arm holding base 233 is moved in the Z-direction (front-back direction) on Figure 5 by the Z-direction moving unit 237. The Z-direction moving unit 237 is moved in the Y-direction (up-down direction) on Figure 5 by the Y-direction moving unit 236. The Y-direction movement unit 236 is moved in the X-direction (left-right direction perpendicular to the Y and Z directions) by the X-direction movement unit 235. As a result, the blocking arm 232 is moved three-dimensionally relative to the lens LE supported by the lens support unit 210.

[0048] Furthermore, the moving unit 230 may include a rotating unit 238 that rotates the cup CU around the axis of the cup mounting axis K2. The rotating unit 238 is equipped with a motor 234. The mounting portion 231 is rotatably positioned around the axis of the cup mounting axis K2. The mounting portion 231 is rotated around the axis of axis K2 via a rotation transmission mechanism (not shown) by the rotation of the motor 234. As a result, when the lens LE has an astigmatism axis (cylindrical axis), the reference horizontal angle of the cup CU is changed, and the cup CU is mounted to the lens LE in a manner that matches the astigmatism axis to the lens prescription.

[0049] The cup mounting device 200 includes a lens information acquisition unit 240 for obtaining information about the lens LE. The lens information acquisition unit 240 may also serve as an optical system for acquiring information about the lens LE other than its optical characteristics (for example, the external shape of the lens LE, the position of marks on the lens LE, hidden marks formed on the lens LE, etc.).

[0050] For example, the lens information acquisition unit 240 includes an illumination optical system 241, a light-receiving optical system 245, and an imaging optical system 248. The illumination optical system 241 includes a light source 242, a half mirror 243, and a concave mirror 244, and illuminates the lens LE along the optical axis L1. A retroreflective member 252 is also positioned below the lens LE, and the light beam reflected by the retroreflective member 252 illuminates the lens LE from behind. The light beam reflected by the retroreflective member 252 is guided to the imaging optical system 248.

[0051] The light-receiving optical system 245 includes a target plate 246, an image sensor 247, etc. For example, the target plate 246 has an index formed by numerous apertures (holes for light beam passage) in a predetermined pattern, and is used to detect the optical center of the lens LE, the astigmatism axis direction, etc. The image sensor 247 is illuminated by the light source 242 and captures the measurement light beam that has passed through the lens LE and the target plate 246. Based on the position of the index image captured by the image sensor 247, the optical center position of the lens LE, the astigmatism axis angle, etc., are detected.

[0052] The imaging optical system 248 includes a concave mirror 244 shared with the illumination optical system 241, an aperture (not specified) positioned at the focal point of the concave mirror 244, an imaging lens (not specified), an image sensor 251, etc. The image sensor 251 captures the reflected light beam reflected by the retroreflective member 252. If a mark is placed on the surface of the lens LE, the position of the mark is detected by analyzing the lens image captured by the image sensor 251. This allows for the detection of the optical center position and the astigmatism axis direction of the lens LE with the mark. Furthermore, the external shape of the lens LE is obtained by analyzing the lens image captured by the image sensor 251.

[0053] The cup mounting device 200 includes a control unit 260. A moving unit 230, a motor 234, and a lens information acquisition unit 240 are connected to the control unit 260. The control unit 260 controls these electrical components. The control unit 260 also controls the lens information acquisition unit 240 to obtain various measurement information. The mounting position of the cup CU may be set to the optical center position of the lens LE, or to the geometric center position of the lens shape. Of course, it may also be set to be mounted at a position other than those described above.

[0054] A detailed example of the configuration of the cup mounting device 200 is described in Japanese Patent Publication No. 2008-299140.

[0055] <Adhesive Tape Dispenser> Figure 6 is a diagram illustrating the schematic configuration of the adhesive tape supply device 300. The adhesive tape supply device 300 includes a base moving unit 310 which functions as a first actuator. The base moving unit 310 is used to move the base sheet 30, which is an example of a base on which the adhesive tape TA is adhered.

[0056] For example, as shown in Figure 7, multiple adhesive tapes TA are arranged on the lower backing 30 at regular intervals. In the example in Figure 7, the adhesive tapes TA are arranged in a single row on the lower backing 30. An upper backing 31 is attached to cover the adhesive tapes TA arranged on the lower backing 30. In other words, the adhesive tapes TA are arranged sandwiched between the lower backing 30 and the upper backing 31. The upper backing 31 is an example of a protective body that protects the adhesive surface on the upper surface of the adhesive tapes TA. The integrated tape 32, in which the lower backing 30 and the upper backing 31 are integrated with the adhesive tapes TA sandwiched in between, is loaded into the adhesive tape supply device 300 in a wound state.

[0057] Furthermore, the adhesive strength of the upper backing paper 31 to the upper surface of the adhesive tape TA is weaker than the adhesive strength of the lower backing paper 30 to the adhesive tape TA. As a result, the upper backing paper 31 peels off from the integrated tape 32 first while the adhesive tape TA remains on the lower backing paper 30. However, the adhesive strength of the upper backing paper 31 to the upper surface of the adhesive tape TA may be the same (including cases where it is approximately the same). Even in this case, the upper backing paper 31 can be gradually peeled off from the integrated tape 32 by providing a trigger for movement in the direction away from the adhesive tape TA.

[0058] Furthermore, the adhesive strength of the base paper 30 to the adhesive tape TA is weaker than the adhesive strength of the adhesive tape TA to the cup CU. This makes it easier for the base paper 30 to peel off when the adhesive tape TA is attached to the fixed surface of the cup CU, as the base paper 30 moves away from the adhesive tape TA. Note that the adhesive strength of the base paper 30 to the adhesive tape TA may be the same (including cases where they are approximately the same). Even in this case, by providing a trigger for the base paper 30 to move away from the adhesive tape TA, the base paper 30 can gradually detach from the adhesive tape TA while the adhesive tape TA remains attached to the cup CU.

[0059] In Figure 6, the base movement unit 310 includes two timing pulleys 312 and 314, a belt (timing belt) 316 stretched between the two timing pulleys 312 and 314, and a motor 318 for rotating the timing pulley 312. The lower base 30 is placed on the belt 316. The belt 316 is moved in the feed direction by the motor 318.

[0060] The adhesive tape supply device 300 may also include a protective peeling unit 330 that functions as a second actuator. The protective peeling unit 330 is used to peel the top backing paper 31 from the integrated tape 32 (i.e., the upper surface of the adhesive tape TA). In Figure 6, the protective peeling unit 330 is positioned on the base moving unit 310. The protective peeling unit 330 includes two timing pulleys 332 and 334, a belt (timing belt) 336 stretched between the two timing pulleys 312 and 314, and a motor 338 for rotating the timing pulley 332. The integrated tape 32 is positioned so as to be sandwiched between the belt 316 of the base moving unit 310 and the belt 336 of the protective peeling unit 330.

[0061] The protective material peeling unit 330 may include an upper backing guide mechanism 340. The upper backing guide mechanism 340 guides the movement of the upper backing 31 in a direction away from the plane on which the adhesive tape TA is installed (upward in the embodiment of Figure 6). For example, the upper backing guide mechanism 340 includes a timing pulley 334 for moving the belt 336 upward, and a roller 342 positioned above the timing pulley 334. The roller 342 is positioned so as to press down on the belt 336 with the upper backing 31 sandwiched between the roller 342 and the belt 336. The roller 342 rotates in sync with the movement of the belt 336, guiding the upper backing 31 peeled off the adhesive tape TA upward. The upper backing 31 is disposed of in a circulating container (not shown).

[0062] The base unit 310 may include a lower backing guide mechanism 320. The lower backing guide mechanism 320 guides the movement of the lower backing 30 in a direction away from the plane on which the adhesive tape TA is installed (downward in the embodiment of Figure 6). For example, the lower backing guide mechanism 320 includes a timing pulley 314 for moving the belt 316 downward and a roller 322 positioned below the timing pulley 314. The roller 322 is positioned so as to press down on the belt 316 with the lower backing 30 sandwiched between the roller 322 and the belt 316. As the roller 322 rotates in sync with the movement of the belt 316, the lower backing 30 is guided in a direction away from the adhesive tape TA (downward in the embodiment). Specifically, the lower backing 30 moves downward together with the belt 316 along the arc of the timing pulley 314. The lower backing 30, guided downward, is discarded into a collection container (not shown).

[0063] Furthermore, the adhesive tape supply device 300 may include an object sensor 350, which is an example of an object detection means for detecting the presence of an object. For example, the object sensor 350 is positioned to detect the adhesive tape TA on the lower backing 30, which is moved by the belt 316 after the upper backing 31 has been peeled off by the protective body peeling unit 330. Note that the object sensor 350 only needs to be able to detect the position of the adhesive tape TA, and its position is not particularly limited.

[0064] The adhesive tape supply device 300 includes a control unit 360. Motors 318 and 338, and an object sensor 350 are connected to the control unit 360. The control unit 360 controls the driving of motors 318 and 338 based on the detection results of the object sensor 350.

[0065] <System Control Unit> Figure 8 shows the overall control unit of the eyeglass lens processing system 2. The adhesive tape application system 1 is equipped with a control unit 600 that controls the entire system. The control unit 600 is connected to the control unit 139 of the robot arm 100, the control unit 260 of the cup attachment device 200, and the control unit 360 of the adhesive tape supply device 300. In this embodiment, the control unit 600 also serves as the overall control unit for the eyeglass lens processing system 2 and is also connected to the control unit 410 of the eyeglass lens processing device 400 and the control unit 510 of the tray transport device 500. The connection to the control unit 600 is not limited to wired connections and may be wirelessly connected.

[0066] The control device 600 works in cooperation with the control units (139, 260, 360, 410, 510) of each device that constitutes the adhesive tape application system 1 and the spectacle lens processing system 2 to control the operation of each device. The control units of each device may be included in the control device 600. The control device 600 is connected to the operation unit 612 and the display unit 614. A host computer 650 is also communicated to the control device 600. For example, the host computer 650 is connected to a database and manages lens processing information necessary for processing the periphery of the lens LE. The control device 600 obtains lens processing information of the lens LE placed in the tray TR via the host computer 650. For example, the lens processing information includes at least one of the following: the target lens shape for periphery processing of the lens LE, layout data (data on the positional relationship of the optical center of the lens LE to the lens shape), and lens LE prescription data (astigmatism axis angle, prescription power for negative or positive power, etc.).

[0067] <Operation> The operation of the spectacle lens processing system 2, which has the above configuration, will be explained using Figure 9. Figure 9 illustrates the operation of attaching the cup CU to the adhesive tape TA and the operation of detaching the adhesive tape TA attached to the cup CU from the base paper 30.

[0068] <Preparation process> First, the control device 600 controls the adhesive tape supply device 300 and prepares it for attaching the adhesive tape TA to the fixed surface of the cup CU. The control device 600 controls the base movement unit 310 and moves the lower backing paper 30 in a predetermined feed direction, thereby moving the adhesive tape TA to the first position P1 (the position where the cup CU is placed). Specifically, under the control of the control unit 360, which receives a control command from the control device 600, the base movement unit 310 and the protective body peeling unit 330 are driven synchronously, and the belt 316 and belt 336 move at the same speed in the feed direction (direction of arrow A in Figure 9(a)). As a result, the integrated tape 32 moves in the feed direction. Then, as the roller 342 rotates synchronously with the movement of the belt 336, the upper backing paper 31, which is located between the roller 342 and the belt 336, is guided upward by the upper backing paper guiding mechanism 340. Meanwhile, the belt 316 extends longer in the feed direction than the belt 336, and the lower backing paper 30 placed on the belt 336 is guided and pulled downward by the lower backing paper guide mechanism 320. As a result, the upper backing paper 31 is peeled off the adhesive tape TA first. The position of the adhesive tape TA from which the upper backing paper 31 has been peeled is detected by the object sensor 350, and based on this detection information, it is moved to the first position P1. After that, the movement of the lower backing paper 30 (movement of the belt 316) is stopped, and the adhesive tape TA is put into a standby state.

[0069] The control device 600 also acquires lens processing information for the lens LE (including lens shape, layout data, and prescription data including astigmatism axis angle). For example, a work sheet for a pair of left and right lens LEs is attached to the tray TR. A barcode is attached to the work sheet, and this barcode is read by a barcode reader (not shown in the illustration). The read barcode is transmitted to the host computer 650. The host computer 650 reads the lens processing information stored in association with the barcode from the database and transmits it to the control device 600. As a result, the control device 600 acquires the lens processing information for the pair of left and right lens LEs.

[0070] <Process for installing eyeglass lenses into the cup mounting device> Next, the control device 600 controls the robot arm 100 to place the lens LE in a predetermined position on the cup mounting device 200. Specifically, the control unit 139, upon receiving a control command from the control device 600, drives the arm 130 and the holding unit 137. The lens LE (one of a pair of spectacle lenses) placed in a predetermined position on the tray TR is then held by the holding unit 137 and transported, and the lens LE is placed on the lens support mechanism 210 of the cup mounting device 200.

[0071] <Process of applying adhesive tape to the cup> Next, the control device 600 controls the robot arm 100 to hold the cup CU with the holding part 137, and then moves the holding part 137 while it is holding the cup CU, thereby attaching the cup CU to the adhesive tape TA. Specifically, the control unit 139, which receives a control command from the control device 600, drives the arm 130 and the holding part 137, and the cup CU, which is placed in a predetermined position on the tray TR, is held by the holding part 137. In this embodiment, the cup CU is held by the holding part 137 by the two fingers 137a that grip both longitudinal edges of the flange 11 of the cup CU. Alternatively, the hooks 12 on both sides of the cup CU may be held by the two fingers 137a. With the cup CU held by the holding part 137, the holding part 137 is moved by the operation of the arm 130, and as shown in Figure 9(a), the cup CU is placed on the adhesive tape TA located at the first position P1, thereby attaching the cup CU to the adhesive tape TA. At this time, the rotation angle of the holding part 137 around the rotation axis X6 is controlled so that the longitudinal direction of the flange portion 11 of the cup CU coincides with the longitudinal direction of the adhesive tape TA.

[0072] <Cup holding process using blocking arm> Next, after the cup CU is attached to the adhesive tape TA, the control device 600 controls the cup mounting device 200 to hold the cup CU attached to the adhesive tape TA with the blocking arm 232. Specifically, first, the control unit 360, which receives a control command from the control device 600, controls the drive of the base movement unit 310, and moves the lower base 30 and the cup CU attached to the adhesive tape TA to the second position P2 where the blocking arm 232 will hold it. Moving the cup CU from the first position P1 to the second position P2 makes it easier for the blocking arm 232 to hold the cup CU. Also, it does not need to enlarge the movement mechanism of the blocking arm 232. Note that the lower base 30 and the cup CU may not be moved to the second position P2, and the cup CU may be held by the blocking arm 232 at the first position P1.

[0073] Next, the control unit 260, having received a control command from the control device 600, controls the drive of the moving unit 230, and after the mounting portion 231 of the blocking arm 232 is moved onto the cup CU located at the second position P2, the blocking arm 232 is lowered. As a result, the base portion 10 of the cup CU is inserted into the insertion hole 231a of the mounting portion 231. The insertion hole 231a of the mounting portion 231 contains a plunger that applies a load to hold the cup CU. As a result, the cup CU is held by the blocking arm 232 via the mounting portion 231.

[0074] <Process of removing adhesive tape attached to the cup from its base> Next, the control device 600 controls both the moving unit 230 of the cup mounting device 200 and the base moving unit 310 of the adhesive tape supply device 300, changing the positional relationship between the cup CU held by the blocking arm 232 and the lower base 30, thereby detaching the adhesive tape TA attached to the cup CU from the lower base 30. Specifically, the control units 260 and 360, upon receiving control commands from the control device 600, drive the base moving unit 310 and the moving unit 230 of the cup mounting device 200, causing the lower base 30 (i.e., the belt 316) to move in the feeding direction, as shown in Figure 9(b). The blocking arm 232 also moves in the feeding direction in synchronization with this movement (i.e., at the same speed). During this movement, the lower backing paper 30 is guided by the lower backing paper guiding mechanism 320 in a direction away from the plane on which the adhesive tape TA is installed (a direction perpendicular to the plane on which the adhesive tape TA is installed, and in this embodiment, downward), and is gradually moved, thereby peeling the lower backing paper 30 from the adhesive tape TA attached to the cup CU. More specifically, in synchronization with the movement of the cup CU held by the blocking arm 232 in the feeding direction, the lower backing paper 30 is moved downward along the arc of the timing pulley 314 together with the belt 316 (i.e., guided by the lower backing paper guiding mechanism 320), so that the lower backing paper 30 is gradually peeled up from the front in the feeding direction of the lower backing paper 30.

[0075] In this way, the lower backing paper 30 is gradually moved by the lower backing paper guide mechanism 320 in a direction away from the installation plane of the adhesive tape TA (it is sufficient that it has a component in a direction perpendicular to the installation plane of the adhesive tape TA) in synchronization with the movement of the cup CU in the feeding direction, thereby allowing the lower backing paper 30 to detach (peel off) from the adhesive tape TA more smoothly.

[0076] <Cup mounting process for cup mounting device> Next, the control device 600 controls the movement unit 230 of the cup mounting device 200 to fix the cup CU to the refractive surface of the lens LE placed in a predetermined position via adhesive tape TA. Specifically, the control unit 260, which receives a control command from the control device 600, first controls the lens information acquisition unit 240 to obtain information such as the optical characteristics of the lens LE. For example, if the lens LE is a single-focus lens, the optical characteristics of the lens LE, such as the optical center position and astigmatism axis angle, are obtained based on the position of the index image captured by the image sensor 247 of the light-receiving optical system 245. If a mark is placed on the lens LE by a lens meter, the position of the mark may be detected by analyzing the lens image captured by the image sensor 251 of the imaging optical system 248, and the optical characteristics of the lens LE, such as the optical center position and astigmatism axis angle, may be obtained based on the detection result.

[0077] Furthermore, the control unit 260, which receives control commands from the control device 600, acquires lens processing information for the lens LE (lens shape, layout data, and astigmatism axis angle of the prescription data).

[0078] Once the optical characteristics of the lens LE (optical center position, astigmatism axis angle) and lens processing information are obtained, the drive of the moving unit 230 is controlled based on this information, and the blocking arm 232 is moved toward the lens LE placed on the lens support unit 210, thereby attaching the cup CU to the refractive surface of the lens LE. For example, the cup CU is attached at the geometric center position of the lens shape. The geometric center position of the lens shape is determined from the acquired optical center position of the lens LE and layout data. The attachment position of the cup CU may also be set to the optical center position of the lens LE. Furthermore, if the lens LE has an astigmatism axis, the mounting part 231 is rotated around the axis of axis K2 based on the acquired astigmatism axis angle and prescription data, so that the astigmatism axis angle of the lens LE and the reference direction of the cup CU are in a constant relationship.

[0079] Once the attachment of the cup CU to the lens LE is complete, the blocking arm 232 is raised and then moved to a predetermined standby position. At this time, since the cup CU is held by the blocking arm 232, the lens LE to which the cup CU is fixed is also lifted and moved together with the cup CU.

[0080] <Process of attaching eyeglass lenses to the lens holding shaft of an eyeglass lens processing machine> Next, the control device 600 controls the robot arm 100 to remove the lens LE together with the cup CU held by the blocking arm 232, then transports it and attaches it to the lens holding shaft 402 of the spectacle lens processing device 400. Specifically, the control unit 139, which receives a control command from the control device 600, drives the arm 130 and the holding unit 137, and the holding unit 137 holds the cup CU or lens LE (in this embodiment, the edges of the flange 11 of the cup CU are gripped by the two fingers 137a of the holding unit 137), and the holding unit 137 is lowered. As a result, the base 10 of the cup CU is removed from the mounting unit 231, and the lens LE with the cup CU is detached. After that, the movement of the arm 130 attaches the cup CU with the lens LE to the lens holding shaft 402L of the spectacle lens processing device 400.

[0081] <Eyeglass lens processing steps> Next, the control device 600 controls the spectacle lens processing device 400 to process the periphery of the lens LE held on the lens holding shaft 402 using the processing tool 460. Specifically, the control unit 410, upon receiving a control command from the control device 600, controls the lens holding mechanism 440, causing the lens holding shaft 402R to move toward the lens holding shaft 402L, thereby holding the lens LE on the lens holding shaft 402. Subsequently, the drive of the moving unit 450 is controlled based on the processing data, so that the periphery of the lens LE is processed by the processing tool 460.

[0082] <Process of returning processed eyeglass lenses to the tray> After the processing of the lens LE is complete, the control device 600 controls the robot arm 100 to hold the lens LE processed by the spectacle lens processing device 400 in the holding unit 137, and removes the lens LE from the lens holding shaft 402L. Subsequently, the control device 600 controls the robot arm 100 to return the processed lens LE held in the holding unit 137 back to the tray TR.

[0083] The other unprocessed lens LE, which is placed in tray TR, is processed in a similar manner, and the processed lens LE is returned to tray TR.

[0084] <Example of transformation> Although a typical embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment, and various modifications are possible.

[0085] For example, the above describes an example in which both the base movement unit 310 and the movement unit 230 of the cup mounting device 200 are controlled when detaching the adhesive tape TA attached to the cup CU from the base paper 30, but the method is not limited to this. The control device 600 may control at least one of the base movement unit 310 and the movement unit 230 of the cup mounting device 200 to change the positional relationship between the cup CU held by the blocking arm 232 (second holding unit) and the base paper 30 (base), thereby detaching the adhesive tape TA attached to the cup CU from the base paper 30.

[0086] For example, the control device 600 may control the moving unit 230 to move the cup CU away from the base sheet 30, thereby detaching the adhesive tape TA from the base sheet 30. For example, the direction away from the base sheet 30 can be perpendicular to the plane on which the adhesive tape TA is attached to the base sheet 30. Specifically, after the blocking arm 232 holds the cup CU, the moving unit 230 may be driven to move the cup CU held by the blocking arm 232 upward, which is an example of the direction away from the cup CU. Because the base sheet 30 is pressed against the belt 316 by the base sheet guide mechanism 320, the base sheet 30 does not follow the upward movement of the adhesive tape TA attached to the cup CU, and the base sheet 30 is peeled off from the adhesive tape TA. In this case, it is preferable that the adhesion of the base sheet 30 to the adhesive tape TA is weaker than the adhesion of the adhesive tape TA to the cup CU.

[0087] Alternatively, the control device 600 may control the base movement unit 310 to move the lower backing sheet 30 in a direction away from the cup CU held by the blocking arm 232 (for example, in a direction having at least a component perpendicular to the plane on which the adhesive tape TA attached to the cup CU is installed). In this case, it is preferable that the lower backing sheet 30 is moved so that it is gradually peeled up from the forward direction in the feeding direction of the lower backing sheet 30.

[0088] Furthermore, although the above assumes that the cup CU is moved to the second position P2 when the blocking arm 232 holds the cup CU, it may remain at the first position P1 when the robot arm 100 attaches the cup CU to the adhesive tape TA. In this case, after the holding part 137 of the robot arm 100 is retracted, the blocking arm 232 is moved to hold the cup CU. In this case, the blocking arm 232 should be configured to be movable to the first position P1 relative to the installation position of the cup mounting device 200.

[0089] Furthermore, in the above embodiment, when holding the cup CU attached to the adhesive tape TA, a blocking arm 232, which is an example of a second holding unit, was used. However, instead of the blocking arm 232, the holding part 137 of the robot arm 100, which is an example of a first holding unit, may be used as the second holding unit. In this case, the robot arm 100 is also used as a second moving unit for moving the second holding unit that holds the cup CU. In this case, following the process of attaching the adhesive tape TA to the cup CU, even in the process of detaching the adhesive tape TA from the base paper 30 attached to the cup CU, the cup CU remains held by the holding part 137, and the detachment from the base paper 30 attached to the cup CU is efficiently performed by moving the robot arm 100 instead of moving the blocking arm 232.

[0090] Then, the robot arm 100 holds and transports the cup CU to which the adhesive tape TA has been attached, and the cup CU is mounted on the mounting section 231 of the blocking arm 232 of the cup mounting device 200. This reduces the constraints on the positional relationship between the cup mounting device 200 and the adhesive tape supply device 300, and increases the degree of freedom in their installation.
