[0009] A setup device to which a reel work device is applied will be described with reference to the drawings. The setup device is a device that performs or supports various setup operations in preparation for the production of a plate product. In the present embodiment, a setup device that performs a reel loading operation of loading a reel into a tape feeder as a setup operation will be explained. 1. Setup device 10

[0010] The setup device 10 is installed, for example, in an offline setup area between a warehouse for storing components (not shown) and a production line in a sheet product manufacturing facility. In the offline setup area, the process of loading the coil 92 into the feeder 91 can be performed automatically by the setup device 10 or manually by a worker. If multiple types of setup devices 10 corresponding to the type of feeder 91 are installed, the setup devices 10 can be interchanged and used. Furthermore, between the offline setup area and the warehouse, and between the offline setup area and the production line, an automated guided vehicle and the worker can transport the feeder 91 and the components. 1-1. Bobbin loading device 11

[0011] As in Fig. 1, the setup device 10 includes a bobbin loading device 11. The bobbin loading device 11 is a bobbin working device that performs a bobbin loading operation into the feeder 91. The bobbin loading device 11 includes a bobbin feeding device 20 and a bobbin attaching / detaching device 40. 1-1-1. Coil feeding device 20

[0012] The bobbin supply device 20 temporarily holds a plurality of bobbins 92 brought in from the outside and supplies the bobbins 92 required for the bobbin attachment / detachment device 40. The bobbin supply device 20 detachably supports the bobbin holding section 22 on an upper surface of the base 21. The bobbin holding section 22 stacks and holds a plurality of bobbins 92 in a horizontal posture (a posture in which a rotation axis of the bobbin 92 is oriented in the vertical direction). The bobbin 92 held by the bobbin holding section 22 may include not only an unused bobbin but also a partially used bobbin.

[0013] The coil holding section 22 holds a plurality of coils 92 by having a round, rod-shaped holding shaft 24 that projects upward from the center of a circular, plate-shaped holding plate 23 and passes through a center hole of the coil 92. The holding section code 25, which indicates identification information (ID) for specifying the coil holding section 22, is attached to the upper surface of the holding plate 23. The holding section code 25 is used to manage a plurality of coils 92 held by the coil holding section 22.

[0014] The bobbin feeder 20 includes a bobbin transfer device 30 serving as a moving device that moves the bobbin 92 to the bobbin attachment / detachment device 40. The bobbin transfer device 30 is provided above the base 21. The bobbin transfer device 30 includes an arm 32 provided to be liftable and lowerable with respect to a vertically extending column 31 and rotatable about a vertical axis.

[0015] The arm 32 is provided with a collecting section 33 that can expand and contract in the horizontal direction. The collecting section 33 detachably accommodates the coil 92. Various aspects can be adopted as a collecting method of the collecting section 33. For example, the collecting section 33 may grip the peripheral edge and the center hole of the coil 92, or may pick up and collect the upper surface (flange surface in the horizontal position) of the coil 92 using negative air pressure.

[0016] The collecting section 33 is equipped with a reader 35. The reader 35 reads the holding section code 25 of the coil holding section 22. The reader 35 can read the coil code 923 attached to the uppermost coil 92 held by the coil holding section 22 or to the coil 92 collected by the collecting section 33. The coil code 923 indicates identification information (ID) specifying the coil 92.

[0017] The bobbin feeder 20 configured as described above is brought into the feed-in area Ac and is configured to feed a plurality of bobbins 92 held by the bobbin holding section 22. When the bobbin transfer device 30 drives the arm 32 and the collecting section 33, the bobbin feeder 20 places a bobbin 92 collected by the bobbin holding section 22 in the placement area Ap or the temporary placement area At on the bobbin attaching / detaching device 40 side in a state where the bobbin 92 is in a horizontal posture. 1-1-2. Bobbin attachment / removal device 40

[0018] The bobbin attaching / detaching device 40 performs an operation of inserting the bobbin 92 necessary for production into the feeder 91 and an operation of removing the bobbin no longer necessary for production from the feeder 91. The bobbin attaching / detaching device 40 includes a feeder holding section 41 that holds the feeder 91 brought in from a feeder feeding device 50, which will be described later.

[0019] When the feeder 91 is held by the feeder holding section 41, the feeder 91 is electrically connected to the setup device 10 via a connector (not shown). Thereby, the feeder 91 is in a state capable of communicating with a controller 13 of the setup device 10, which will be described later, and is in a state capable of driving a drive device that feeds and moves a carrier tape output from the loaded reel 92.

[0020] The bobbin attachment / detachment device 40 includes a setting device 42 that sets the bobbin 92 onto the feeder 91 held by the feeder holding section 41. The setting device 42 collects the bobbin 92 in the horizontal position in the placement area Ap and changes the position to a vertical position (a position where the rotation axis of the bobbin 92 is aligned in the horizontal direction). The fixing device 42 moves the bobbin 92 in the vertical position toward the feeder 91 and causes the feeder 91 to hold the bobbin 92.

[0021] In the above-described placement area Ap, the bobbin 92 to be attached to the feeder 91 held by the feeder holding section 41 is placed in the horizontal position.

[0022] Further, in the temporary placement area At, when it is necessary to change the order in which the setting device 42 sets a plurality of bobbins 92 to the feeder 91, the bobbin 92 in which the set order is shifted is temporarily placed in the horizontal position.

[0023] The setting device 42 has a tape loading function such that the feeder 91 is placed in a loading state in which a carrier tape unwound from the spool 92 can be fed and moved by the drive device. Specifically, the setting device 42 includes, for example, an articulated robot and an image processing device. The setting device 42 detects a leading end portion of the carrier tape through the image processing device. The setting device 42 grips the leading end portion of the carrier tape with the finger of the articulated robot and engages a gear hole of the carrier tape with a gear that forms the drive device of the feeder 91.

[0024] Accordingly, the reel 92 used for production is set on the feeder 91, and the feeder 91 is placed in a loading state in which the carrier tape can be fed and moved. The feeder 91, to which the reel 92 is set, is removed from the feeder holding section 41 and transported out to the feeder supply device 50.

[0025] The coil attaching / detaching device 40 includes a take-out device 43 for removing the coil 92 from the feeder 91 held by the feeder holding section 41. The take-out device 43 moves the movable base 46 along the guide rail 45 and removes the coil 92 attached to the feeder 91 through the collecting section 47 provided on the movable base 46. The take-out device 43 brings the removed coil 92 from the vertical position to the horizontal position and inserts the coil 92 into the unloading section 60, which discharges the coil 92 to the outside of the device. Details of the unloading section 60 will be described later. 1-2. Feeder feeding device 50

[0026] As in Fig. 1, the setup device 10 includes the feeder feeding device 50. The feeder feeding device 50 is installed adjacent to the bobbin loading device 11, temporarily holds a plurality of feeders transported in from the outside, and feeds required feeders 91 to the bobbin loading device 11. The feeder feeding device 50 includes a feeder receiving section 51 detachably provided and a feeder transporting section 52.

[0027] The feeder receiving section 51 is housed alongside other feeder receiving sections 51 in a receiving space of a housing. The feeder receiving section 51 is formed in a box shape having an opening portion in the horizontal direction. The feeder receiving section 51 stores the feeder 91 in a plurality of slots formed in the bottom surface. When the feeder 91 is held in the feeder receiving section 51, the feeder 91 is communicatively connected to the setup device 10 via a connector (not shown).

[0028] The feeder transport section 52 is configured to be movable between the feeder receiving section 51 and the feeder holding section 41. The feeder transport section 52 takes out any feeder 91 from the feeder receiving section 51 and conveys the feeder 91 into the feeder holding section 41. When an unnecessary bobbin 92 is taken out from the feeder 91 and the bobbin required to perform production is loaded into the feeder 91 by the bobbin loading device 11, the feeder transport section 52 transports the feeder 91 out of the feeder holding section 41 and accommodates the feeder 91 in a predetermined slot of the feeder receiving section 51. 1-3. Control unit 13

[0029] As in Fig. 1, the setup device 10 includes a controller 13. The controller 13 controls the operation of the bobbin loading device 11 and the feeder feeding device 50 and performs various operations on the feeder 91. The above-described operation includes, in addition to the bobbin loading operation in the setup operation, the operation of simply removing the bobbin 92 to store the feeder 91 in a warehouse or the like in a state where the bobbin 92 is not loaded.

[0030] The control device 13 obtains a plurality of coils 92 held by the coil holding section 22 transported into the carrying-in area Ac based on the reading result of the holding section code 25 by the reader 35 of the coil transfer device 30. In addition, the control device 13 obtains the uppermost coil 92 held by the coil holding section 22 or the coil 92 collected by the collecting section 33 of the coil transfer device 30 based on the reading result of the coil code 923 by the reader 35.

[0031] The controller 13 obtains the feeder 91 held by the feeder holding section 41 and the feeder 91 received by the feeder receiving section 51 through communication. Based on the instruction of the setup operation, the controller 13 loads the corresponding bobbin 92 into the predetermined feeder 91 or loads the bobbin 92 into the feeder 91 to be loaded.

[0032] When the bobbin 92 is loaded into the feeder 91, the controller 13 also generates allocation information. When the bobbin 92 is removed from the feeder 91, the controller 13 deletes the allocation information. The generation and deletion of the allocation information are shared as needed by a management device higher than the setup device 10. The controller 13 unloads the bobbin 92 using the unloading section 60 in the bobbin unloading process by the unloading device 43. 1-4. Safety device 70

[0033] As in Fig. As shown in Figure 2, the bobbin loading device 11 of the setup device 10 includes a safety device 70. The safety device 70 disables some functions of the bobbin loading device 11 to ensure the safety of the worker when the worker can access the interior of the device. In the present embodiment, the safety device 70 is integrated into the control unit 13 and restricts the operation of the unloading device 43 when the door 15 provided on the cover 14, which separates the interior and exterior of the device, is in the open state.

[0034] Specifically, the safety device 70 includes a door sensor 71 that detects the open state of the door 15. The safety device 70 sends a restriction signal to the controller 13 during a period in which the open state of the door 15 is detected. The removal device 43 of the coil attachment / detachment device 40 performs control such that no operations such as movement and positional changes of the coil 92 are performed during a period in which the restriction signal transmitted from the safety device 70 is input.

[0035] The safety device 70 enables the operation of the removal device 43 when the door 15 is in the closed state. Specifically, when the door 15 is closed, the safety device 70 interrupts the transmission of the restriction signal to the control unit 13. Accordingly, the removal device 43 performs operations such as moving and changing the position of the coil 92 according to the command. 2. Unloading section 602-1. Overview of unloading section 60

[0036] In the bobbin loading device 11 as the bobbin working device configured as described above, the operation of taking out the bobbin 92 from the feeder 91 is performed. At this time, when the taken-out bobbin 92 is continuously introduced into the take-out box installed in the device, for example, the bobbins 92 are stacked up to the number of taken-out bobbins 92 that can be accommodated in the take-out box, and the bobbin taking-out operation cannot be continued.

[0037] To extend the time during which the coil removal process can continue, it is necessary to increase the size of the removal box or increase the frequency of the worker's removal from the removal box. However, due to limited space in the fixture, it is not easy to increase the size of the removal box, and increasing the removal frequency will increase the number of operations by the worker.

[0038] Therefore, in the present embodiment, a configuration is adopted in which the number of removable coils that can be discharged can be increased without increasing the size of the removal box.

[0039] In the present embodiment, the bobbin loading device 11 specifically includes a discharge section 60 that discharges the removed bobbin to the outside of the device. Accordingly, the number of bobbins 92 discharged by the bobbin loading device 11 during the bobbin removal process can be increased. As a result, it is possible to extend the time during which the bobbin removal process can be continued by the bobbin loading device 11. As shown in Fig. 2, the unloading section 60 is configured so that the coil 92 held by the removal device 43 can be inserted in a horizontal position. 2-2. Configuration of the unloading section 60

[0040] As in Fig. 2, the unloading section 60 includes a chute 61 as its main body. The chute 61 is fixed to the installation base 48 in the apparatus. The chute 61 is formed with an inlet 62 into which the removed coil 92 is inserted. The inlet 62 is opened so that the coil 92 can pass through the inlet 62 in a horizontal position. The chute 61 guides the coil 92 inserted into the inlet 62 to the outside of the apparatus. The chute 61 also has a slope 611 that guides the inserted coil to the outside of the apparatus while the coil 92 slides, so that the inserted coil 92 is unloaded in a predetermined position.

[0041] The slope 611 extends from below the inlet 62 to the cover 14. In a lower part of the chute 61, a discharge opening 66 for discharging the coil 92 is formed, which is inclined by an amount corresponding to the inclination of the slope 611 from the horizontal position. The discharge opening 66 communicates with a slot formed in the cover 14 so that the coil 92 can pass therethrough. Below the discharge opening 66, a storage box 67 is detachably installed outside the setup device 10, which stores the feeder 91 discharged to the outside from the discharge section 60. The storage box 67 is used as a storage box that can accommodate a larger number than a take-out box intended for the interior of the device, and the shape can be selected arbitrarily.

[0042] The replacement of the storage box 67 by a worker or the like and the removal of the coil 92 from the storage box 67 correspond to work outside the device. Therefore, the removal work of the coil 92 is not the target of a measure for temporarily interrupting, for example, the coil work (the loading operation or the removal operation of the coil 92) in the device that accompanies the removal of the coil 92, from the viewpoint of ensuring safety or the like.

[0043] In the present embodiment, the box sensor 68 is embedded in a part of the wall surface of the cover 14 that comes into contact with the installed storage box 67. The box sensor 68 detects the storage box 67 installed at a predetermined position and sends a signal to the controller 13. When the storage box 67 is removed by a worker or the like, the box sensor 68 is in a state where it does not detect the storage box 67 and stops transmitting the signal to the controller 13. 3. Unloading tax section 80

[0044] In the present embodiment, as shown in Fig. 3, the control device 13 includes a discharge control section 80 that controls the discharge operation of the coil 92 as part of the coil removal process. The discharge control section 80 controls the operation of the removal device 43 using various functions of the control device 13. As shown in Fig. 4, the unloading control section 80 also performs a process of unloading the bobbin 92 after the take-out device 43 takes out the bobbin 92 from the feeder 91. 3-1. Detection Section 81

[0045] As in Fig. 3, the unloading control section 80 includes a detection section 81. The detection section 81 detects the installation of the storage box 67 that receives the feeder 91 discharged from the unloading section 60 to the outside of the apparatus. Specifically, when the storage box 67 is installed at a predetermined position outside the apparatus, the box sensor 68 embedded in the cover 14 detects the storage box 67, and a signal is transmitted. The detection section 81 detects that the storage box 67 is installed while the signal is input. When the storage box 67 is removed, for example, by a replacement operation or the like, and the transmission of the signal by the box sensor 68 is stopped, the detection section 81 detects that the storage box 67 is not installed. 3-2. Unloading Restriction Section 82

[0046] As in Fig. 3, the discharge control section 80 includes a discharge restriction section 82. If the storage box 67 is not recognized by the detection section 81 (S11: No in Fig. 4), the discharge restricting portion 82 restricts the discharge of the coil 92 to the outside of the device. Specifically, the discharge restricting portion 82 prevents the extraction device 43 from inserting the coil 92 held by the extraction device 43 into the discharge portion 60 (S21).

[0047] When the storage box 67 is detected by the detection section 81 (S11: Yes), the discharge restriction section 82 allows the take-out device 43 to insert the coil 92 into the discharge section 60 (S12). In this way, the discharge restriction section 82 determines whether the coil 92 can be inserted into the discharge section 60 according to the presence or absence of the storage box 67 outside the device. Accordingly, for example, the coil 92 can be prevented from being discharged even when the storage box 67 is not installed. 3-3. Notification Section 83

[0048] As in Fig. As shown in Figure 3, the discharge control section 80 includes a notification section 83. The notification section 83 performs various notification operations to the worker. The notification operations are performed by lighting an indicator lamp, performing notification to a terminal device carried by the worker, or the like. For example, when the discharge of the coil 92 is restricted by the discharge restriction section 82 (S21), the notification section 83 notifies the worker that the storage box 67 is not installed (S22).

[0049] Furthermore, the discharge control section 80 accumulates the number of coils 92 whose discharge is permitted by the discharge restriction section 82 (S12) and which are actually introduced into the discharge section 60 by the take-out device 43. When the number of introduced coils 92 reaches a predetermined reference value (S13: Yes), the notification section 83 performs a notification corresponding to the number of coils 92 discharged from the discharge section 60 (S14). The "reference value" is set, for example, according to the number of coils that can be stored in the storage box 67. The notification section 83 performs a notification to encourage the replacement of the storage box 67 or the removal of the coil 92 before the storage box 67 is filled by inserting the coils 92 a predetermined number of times. 4. Effects of the configuration of the embodiment

[0050] According to the above configuration, the bobbin 92 taken out from the feeder 91 is discharged to the outside of the apparatus, and the number of taken-out bobbins 92 that can be discharged can be increased without increasing the size of the take-out box in the apparatus. Consequently, it is possible to extend the time during which the bobbin removal process can be continued by the bobbin loading device 11 as a bobbin working device. 5. Modification of the Embodiment 5-1. Unloading Section

[0051] In the embodiment, the discharge section 60 is fixed to the installation base 48 of the setup device 10 inside the device, and the discharge opening 66 of the chute 61 communicates with the slot of the cover 14. As shown in Fig.Meanwhile, as shown in Fig. 5, the removal box 49, which is similar to the conventional removal box, can be detachably installed on the installation base 48. Thus, the setup process can be performed without installing the storage box 67 outside the setup device 10.

[0052] Furthermore, considering the contents of the setup process and the time during which the coil removal process can be continued, the unloading section 160 may be attached to the installation base 48, and a storage box 67 may be installed instead of the removal box 49 intended for the interior of the device. This makes it possible to adapt to various operations such as the installation status of the setup device 10 and the type of setup process.

[0053] The unloading sections 60 and 160 each include an inlet 62 and a chute 61. Meanwhile, the unloading section can take various forms as long as the coil 92 can be unloaded to the outside of the apparatus. For example, the unloading section may be configured to unload the coil 92 via a conveyor or the like. Alternatively, the unloading section may be configured to receive the coil 92 from the take-out device 43 in the vertical position, rotate the coil 92 by its own weight, and guide the coil 92 out of the apparatus. The coil processing apparatus may include a plurality of unloading sections. For example, the coil processing apparatus may sort the coils and unload them to a plurality of unloading sections with different unloading destinations depending on the purpose.The above task includes, for example, sorting between a reel in which a component remains and a reel in which the component is completely consumed, and sorting according to the reel material. 5-2. Coil working device

[0054] In this embodiment, for example, the bobbin working device is the bobbin loading device 11 that loads the bobbin 92 into the feeder 91. Meanwhile, the bobbin working device includes the take-out device 43 that takes out the bobbin 92 from the feeder 91 held by the feeder holding section 41. The unloading sections 60 and 160 can be used as long as the bobbin working device has at least a bobbin unloading function. The same effect can be achieved with such a configuration.

[0055] The bobbin loading device 11 as the bobbin working device includes the detection section 81, the discharge restriction section 82, and the notification section 83. Meanwhile, the bobbin loading device 11 may have a configuration in which some of them are omitted, for example, a configuration in which the storage box 67 or the take-out box 49 is normally installed in the bobbin loading device 11, and the detection section 81 or the discharge restriction section 82 is not provided. Some of the notification processes (S14, S22) by the notification section 83 may be omitted. However, from the viewpoint of maintaining the efficiency of the setup process, the aspect shown in the embodiment is preferable. List of reference symbols
