(Configuration of feeder 50)
The configuration of the feeder 50 will be described with reference to FIGS. The feeder 50 is set in the slots S <b> 1 to Sn of the component supply device 20. The feeder 50 is supplied with a carrier tape 81 wound around a reel 80. As shown in FIG. 2, the feeder 50 feeds and moves the carrier tape 81 inserted from the insertion portion Di, and supplies the component at the take-out portion Dt so that it can be taken out. Thus, the feeder 50 is a tape feeder that employs a tape type in the present embodiment.

  As shown in FIG. 2, the feeder 50 includes a feeder main body 51, rails 52, a pair of first sprockets 53, a pair of second sprockets 54, a tape delivery unit 55, a tape guide 56, and an operation panel 57.

The feeder main body 51 has a flat box shape, and an insertion portion Di into which the carrier tape 81 is inserted is formed. The insertion portion Di is located on the rear side (left side in FIG. 2) of the feeder main body 51. In the present embodiment, the feeder main body 51 is provided with a reel holder 51 a that can hold the reel 80.

  The rail 52 constitutes a conveyance path that supports the carrier tape 81 inserted from the insertion portion Di. The pair of first sprockets 53 is provided below the rail 52 in the take-out part Dt. The pair of second sprockets 54 is provided below the rail 52 in the insertion portion Di. The first sprocket 53 and the second sprocket 54 are arranged so that a part of the first sprocket 53 and the second sprocket 54 protrudes from the window portion formed on the rail 52 to the upper surface side of the rail 52, and can be engaged with the feed hole of the carrier tape 81. The

  The first sprocket 53 and the second sprocket 54 are rotationally driven independently of each other by a stepping motor (not shown) or rotationally driven in synchronization. From such a configuration, the first sprocket 53 is driven so as to draw the carrier tape 81 on the rail 52 into the take-out portion Dt. Further, the second sprocket 54 feeds and moves the start end of the carrier tape 81 from the insertion portion Di to the first sprocket 53 when the start end of the carrier tape 81 is inserted into the insertion portion Di.

  The tape delivery unit 55 is disposed above the rail 52 where the second sprocket 54 is located in the transport direction of the carrier tape 81. The tape delivery unit 55 presses the carrier tape 81 interposed between the tape 52 and the rail 52 against the rail 52. Thereby, the tape delivery unit 55 guides the engagement between the feed hole of the carrier tape 81 and the second sprocket 54. Further, the tape delivery unit 55 holds the replenishment carrier tape 81 that is inserted in a reserved manner with respect to the carrier tape 81 in use in a state where it is stacked.

  The tape guide 56 is disposed above the rail 52 where the first sprocket 53 is positioned in the transport direction of the carrier tape 81. The tape guide 56 regulates the upward movement and the widthwise movement of the carrier tape 81 engaged with the first sprocket 53 and guides the engagement between the carrier tape 81 and the first sprocket 53. The tape guide 56 peels off the cover tape of the carrier tape 90 and exposes the electronic component so that it can be taken out.

  As shown in FIG. 1, the operation panel 57 is disposed at a position located outside the electronic component mounting machine 1 in a state where the feeder 50 is set on the electronic component mounting machine 1. As shown in FIG. 3, the operation panel 57 is provided with an indicator lamp for notifying the state of the power supply and the presence of an error, and a plurality of operation switches. The operation panel 57 receives a manual operation by an operator via an operation switch and sends a signal to the feeder control unit 58. The operation switches include a feed switch for transporting the carrier tape 81 and a return switch.

  The feeder control unit 58 is mainly configured by a CPU, various memories, and a control circuit. When the feeder 50 is set in the electronic component mounting machine, the feeder control unit 58 is supplied with electric power from the electronic component mounting machine via the connector and can communicate with the electronic component mounting machine. The feeder control unit 58 controls the operations of the first sprocket 53 and the second sprocket 54 based on control commands from the electronic component mounting machine, signals from the operation panel 57, and detection results from various sensors.

  With this configuration, the feeder 50 automatically feeds and moves the start end of the carrier tape 81 to the take-out portion Dt by driving the second sprocket 54 after the start end of the carrier tape 81 is inserted into the insertion portion Di. Thereby, the feeder 50 is loaded with the carrier tape 81 so that the electronic component can be supplied at the take-out part Dt. Thus, the feeder 50 of this embodiment is an auto loading type which has a feeding mechanism (second sprocket 54) in the insertion portion Di.

  The identification code 59 indicates unique information of the feeder 50 such as an identification code (ID). As the identification code 59, any one of a barcode, a two-dimensional code, a character string, a pattern, a color, or a combination thereof can be used. In the present embodiment, as shown in FIG. 3, the identification code 59 employs a barcode configured by arranging a plurality of bar lines having different line widths and intervals between the lines in parallel.

  The identification code 59 is read by the reader 70 in a registration process for registering the electronic component type in association with the feeder 50 (see FIG. 4). The unique information of the feeder 50 acquired in this way is managed together with the type of electronic component supplied by the feeder 50, for example. The control device 40 of the electronic component mounting machine 1 stores the set feeder 50 and the type of electronic component supplied by the feeder 50 in association with each of the slots S1 to Sn. Details of the registration process will be described later.

  In addition to the direct input by the operator, the type of electronic component is input by reading the identification code 82 attached to the reel 80 around which the carrier tape 81 for storing the electronic component is wound. The identification code 82 attached to the reel 80 indicates individual information including the type of electronic component, and corresponds to the “second identification code” of the present invention.

  The switching device 60 switches between a display state in which the identification code 59 can be read and a non-display state in which the identification code 59 cannot be read. The switching device 60 is disposed at a position located outside the electronic component mounting machine 1 in a state where the feeder 50 is set on the electronic component mounting machine 1. Specifically, the switching device 60 is disposed on the rear side of the feeder main body 51 with respect to the boundary line Lb in FIG. The boundary line Lb indicates the boundary between the inside and outside of the electronic component mounting machine 1 in the Y-axis direction.

  Further, in the present embodiment, the switching device 60 is disposed above the insertion portion Di into which the carrier tape 81 is inserted and below the operation panel 57. With such a configuration, the switching device 60 reads the identification code 59 placed in a position operable by the operator and in the display state with the reader when the feeder 50 is set in the electronic component mounting machine 1. Is configured to be possible.

  As illustrated in FIG. 3, the switching device 60 includes a moving member 61, a storage portion 62, and a drive mechanism 63. The moving member 61 is formed in a shape extending in the front-rear direction of the feeder body 51. The moving member 61 is formed in a U shape whose cross section perpendicular to the longitudinal direction opens downward. At the end of the moving member 61, there is provided a gripping portion 61a that protrudes downward and can be gripped by the operator. An identification code 59 is attached to the upper surface 61 b of the moving member 61. Specifically, a seal printed with a barcode (identification code 59) is attached to the upper surface 61b of the moving member 61.

  The storage portion 62 is formed in a cylindrical shape and is fixed to the feeder main body 51. The accommodating part 62 supports the moving member 61 arrange | positioned inside, and guides the moving member 61 so that sliding is possible. In the present embodiment, the storage unit 62 guides the moving member 61 so that the sliding direction of the moving member 61 with respect to the storage unit 62 is substantially horizontal. In the present embodiment, the moving member 61 and the storage portion 62 constitute a slide mechanism that can slide the moving member 61 in the horizontal direction. The storage unit 62 stores the moving member 61 and puts the identification code 59 in a non-display state.

  The drive mechanism 63 includes a rack 61c formed on the moving member 61, a pinion 63a disposed on the feeder body 51, and a motor 63b. The rack 61c is formed inside a main body portion formed in a U shape that opens downward in the moving member 61. The rack 61 c is formed in a predetermined region in the extending direction of the moving member 61. The pinion 63 a meshes with the rack 61 c of the moving member 61. The motor 63b is supplied with electric power based on control by the feeder controller 58, and rotates the pinion 63a.

  According to such a configuration, the pinion 63a is rotated by driving the motor 63b, and the moving member 61 is moved in the horizontal direction according to the rotation amount of the pinion 63a. The identification code 59 attached to the moving member 61 is brought into a readable display state (the state shown in FIG. 3) when the moving member 61 is moved to the outside of the storage portion 62. On the other hand, when the moving member 61 is accommodated in the accommodating part 62, the identification code 59 will be in the non-display state (state shown in FIG. 2) which cannot be read.

(Detailed configuration of the control device 40)
A detailed configuration of the control device 40 will be described with reference to FIGS. 5 and 6. The control device 40 includes a mounting control unit 41, a storage device 42, a determination unit 45, and a switching control unit 46. The mounting control unit 41 controls the position of the mounting head 33 and the operation of the suction mechanism. More specifically, the mounting control unit 41 inputs information output from various sensors provided in the electronic component mounting machine 1 and results of various recognition processes. Then, the mounting control unit 41 sends a control signal to the component transfer device 30 based on a control program stored in the storage device 42, information from various sensors, and the like. Thereby, the position and rotation angle of the suction nozzle supported by the mounting head 33 are controlled.

  The storage device 42 is configured by an optical drive device such as a hard disk device or a flash memory. The storage device 42 stores job data including control programs and various control information, image data, temporary data for image processing, and the like. Note that, as shown in FIG. 6, the job data includes information for designating the type of electronic component supplied by the feeder 50 for each of the plurality of slots S <b> 1 to Sn in the mounting process by the electronic component mounting machine 1. ing.

  The determination unit 45 determines whether it is necessary to read the identification code 59 of the feeder 50. Specifically, whether the determination unit 45 should be in a display state in which the identification code 59 can be read or not in a non-displayable state based on the presence or absence of a request from the operator or the current process in the registration process. Determine. In the present embodiment, the determination unit 45 determines whether the electronic component type is directly input by the operator in the registration process or when the identification code 82 attached to the reel 80 is read and input. It is determined that the identification code 59 needs to be read.

  The switching control unit 46 controls the operation of the switching device 60 of the feeder 50 based on the result of determination by the determination unit 45. In the present embodiment, the switching control unit 46 controls the operation of the drive mechanism 63 so that the display state and the non-display state are switched depending on the relative position of the moving member 61 with respect to the storage unit 62. Specifically, the switching control unit 46 sets the motor of the drive mechanism 63 so that the moving member 61 is sent out from the storage unit 62 when the determination unit 45 determines that the identification code 59 of the feeder 50 needs to be read. The power supply to 63b is controlled.

  On the other hand, when the determination unit 45 determines that reading of the identification code of the feeder 50 is unnecessary, the switching control unit 46 controls the motor 63b of the drive mechanism 63 so that the moving member 61 is stored in the storage unit 62. Control power supply. Further, the switching control unit 46 controls the switching devices 60 of the plurality of feeders 50 set in the plurality of slots S1 to Sn. Which feeder 50 switching device 60 is to be operated is determined based on, for example, the type of electronic component and job data.

(Details of registration process)
A registration process for registering the electronic component type in association with the feeder 50 will be described with reference to FIGS. The registration process is executed at the time of replacement of production of circuit board products or supply of parts requiring replacement of the reel 80. Here, the feeder 50 is set in each of the slots S <b> 1 to Sn of the component supply device 20, and the identification code 59 (hereinafter also referred to as “feeder code 59”) of the feeder 50 is hidden by the switching device 60. Shall.

  The control device 40 of the electronic component mounting machine 1 also functions as a feeder control device for the feeder 50. As shown in FIG. 7, the determination unit 45 of the control device 40 determines whether or not it is necessary to read the feeder code 59 (step 11 (hereinafter, “step” is expressed as “S”)). Specifically, the determination unit 45 determines whether or not the feeder code 59 needs to be read based on whether or not an electronic component type is input.

  Here, the input of the type of electronic component is made by reading an identification code 82 (hereinafter also referred to as “reel code 82”) attached to the reel 80 using a reader 70 connected to the electronic component mounting machine 1. The When the reel code 82 is read and the type of the electronic component indicated by the reel code 82 is input, the determination unit 45 determines that the feeder code 59 needs to be read (S11: Yes).

  On the other hand, while the reel code 82 is not read, the determination unit 45 determines that it is not necessary to read the feeder code 59 (S11: No). In other words, the determination unit 45 is in a state of waiting for an input of the electronic component type. Further, the feeder code 59 is maintained in the initial non-display state.

  Next, the switching control unit 46 designates a designated slot in which the type of the electronic component among the plurality of slots S1 to Sn is designated based on the inputted type of electronic component and job data (see FIG. 6). Is specified (S12). In order to improve the efficiency of the mounting process by the electronic component mounting machine 1, the job data is optimized in consideration of the mounting frequency for each type of electronic component, the distance from the feeder 50 to the mounting position, and the like. Accordingly, the job data includes information for designating the type of electronic component for each of the plurality of slots S1 to Sn.

  Subsequently, the switching control unit 46 controls the operation of the switching device 60 of the feeder 50 set in the specified designated slot (S13). Specifically, the switching control unit 46 controls the supply of electric power to the motor 63 b of the drive mechanism 63 so that the moving member 61 is sent out from the storage unit 62. Thereby, the moving member 61 slides and is moved to the relative position protruding from the storage portion 62. Then, the feeder cord 59 attached to the upper surface 61b of the moving member 61 is exposed, and a readable display state is obtained. When a plurality of designated slots are specified in S12, the switching control unit 46 similarly controls the operation of the switching device 60 of the feeder 50 set in each designated slot.

  Here, since the designated slot is defined by optimizing the job data as described above, for example, the operator who performs the setup change designates the feeder 50 set in the designated slot so as to match the job data. The reel 80 needs to be replenished. On the other hand, the operator can specify the feeder 50 set in the designated slot from the plurality of feeders 50, using the switching device 60 as the indicator to display the feeder code 59. It becomes.

  The switching control unit 46 determines whether or not the feeder code 59 has been read using the reader 70 (S14). When the operator reads the feeder code 59 (S14: Yes), the unique information of the feeder 50 is input to the control device 40. On the other hand, when the feeder code 59 is not read (S14: No), the switching control unit 46 is in a state of waiting for the feeder code 59 to be read, and the display state of the feeder code 59 is maintained.

  The control device 40 registers the input electronic component type in association with the unique information of the feeder 50 set in the designated slot. As a result, the control device 40 recognizes that the feeder 50 having the specific information is set in the designated slot, and a specified type of electronic component is supplied by the feeder 50. Further, the determination unit 45 determines that reading of the feeder code 59 is no longer necessary when the above registration is properly performed.

  The switching control unit 46 controls the operation of the switching device 60 of the feeder 50 set in the designated slot based on the determination result by the determination unit 45 (S13). Specifically, the switching control unit 46 controls the supply of electric power to the motor 63 b of the drive mechanism 63 so that the moving member 61 is stored in the storage unit 62. Thereby, the moving member 61 slides and is moved to the relative position where the main body is stored in the storage portion 62. And the feeder code 59 attached | subjected to the upper surface 61b of the moving member 61 is hidden, and it is set as the non-display state which cannot be read. When a plurality of designated slots are specified in S12, the switching control unit 46 similarly controls the operation of the switching device 60 of the feeder 50 set in each designated slot.

(Effects of the configuration of the embodiment)
The feeder control device 40 targets the feeder 50 used for supplying electronic components in the electronic component mounting machine 1. The feeder 50 includes a switching device 60 that switches between a display state in which an identification code 59 (feeder code 59) indicating unique information of the feeder 50 can be read and a non-display state in which the identification code 59 cannot be read. The control device 40 includes a determination unit 45 that determines whether it is necessary to read the identification code 59 of the feeder 50, and a switching control unit 46 that controls the operation of the switching device 60 based on the determination result by the determination unit 45. Prepare.

According to such a configuration, the operation of the switching device 60 of the feeder 50 is controlled in accordance with the necessity of reading the identification code 59 (feeder code 59). Thereby, since the display state and non-display state of the identification code 59 are automatically switched, man-hours required for the reading operation are reduced, and the reading operation can be simplified.
The switching control unit 46 controls the identification code 59 to be unreadable when it is determined that reading of the identification code 59 is unnecessary (S16). That is, the identification code 59 attached to the feeder 50 that is not subject to the reading operation is not displayed. Accordingly, even if the same type of feeder 50 is set in the electronic component mounting machine 1 so as to be adjacent to each other, it is possible to prevent the identification code 59 attached to the feeder 50 that is not subject to the reading operation from being erroneously read, and the reading can be performed. It can be done more accurately. Thereby, the manageability of the feeder 50 can be improved.
In addition, the operator can visually recognize the feeder 50 that is the object of the reading work with the operation of the switching device 60 in the reading work. Therefore, even when the plurality of feeders 50 are set in the slots S1 to Sn, it is easy to find the feeder 50 that is the target of the reading operation, and the reading workability can be improved.

  The switching device 60 includes a moving member 61 to which an identification code 59 is attached, a storage unit 62 that guides the movement of the moving member 61 and stores the moving member 61 so that the identification code 59 is not displayed. And a drive mechanism 63 that moves the moving member 61 relative to the storage portion 62. The switching control unit 46 controls the operation of the drive mechanism 63 so that the display state and the non-display state are switched according to the relative position of the moving member 61 with respect to the storage unit 62 (S13, S16).

  According to such a configuration, when the moving member 61 is exposed from the storage portion 62 by the operation of the drive mechanism 63, the identification code 59 attached to the moving member 61 is displayed (S13). If it is determined that reading of the identification code 59 is unnecessary, the moving member 61 is accommodated in the accommodating portion 62 by the operation of the drive mechanism 63, and the identification code 59 is not displayed (S16). As a result, it is possible to reliably switch between the display state and the non-display state. In addition, the operator can easily find the feeder 50 that is the object of the reading operation by the movement of the moving member 61.

  Further, in the registration process for registering the electronic component type in association with the feeder 50, the determination unit 45 determines that it is necessary to read the identification code 59 of the feeder 50 when the electronic component type is input (S11). .

  According to such a configuration, during the registration process, the electronic component type is input to the feeder 50 (or the slot in which the feeder 50 is set) for the purpose of associating the electronic component type. The determination unit 45 determines that it is necessary to read the identification code 59 of the feeder 50 based on this input. Thereby, the switching device 60 of the feeder 50 is operated, and the identification code 59 is automatically displayed. The workability of reading and the manageability of the feeder 50 can be improved.

  Further, the electronic component mounting machine 1 includes a plurality of slots S1 to Sn in which the feeder 50 is set. The control device 40 further includes a storage device 42 that stores job data for designating the type of the electronic component supplied by the feeder 50 for each of the plurality of slots S1 to Sn in the mounting process by the electronic component mounting machine 1. Based on the type of electronic component input in the registration process and the job data, the switching control unit 46 identifies a designated slot in which the type of the electronic component is designated from among the plurality of slots S1 to Sn. The operation of the switching device 60 of the feeder 50 set in the designated slot is controlled.

  According to such a configuration, the operator can recognize from which feeder 50 of the plurality of feeders 50 the electronic component whose type has been input should be supplied by the operation of the switching device 60. Therefore, the step of confirming the combination of the electronic component and the feeder 50 (or slots S1 to Sn) in advance can be omitted, and the reading operation can be simplified. Moreover, since it can prevent registering with an incorrect combination, the manageability of the feeder 50 can be improved.

  Further, the determination unit 45 identifies the feeder 50 on the assumption that the second identification code (reel code 82) indicating the individual information including the electronic component type is read and the electronic component type is input in the registration process. It is determined that the code 59 needs to be read.

  According to such a configuration, the input of the electronic component type is performed by reading the second identification code (reel code 82). Therefore, in the registration process, the operator first performs a work of reading the second identification code (reel code 82) with a reader to find the feeder 50 in which the switching device 60 is operated. For example, the carrier tape in which the electronic component is stored. The reel 80 around which the 81 is wound can be a target to be replenished. Furthermore, the registration process can be executed by reading the identification code 59 of the feeder 50.

In the embodiment, the drive mechanism 63 of the switching device 60 is of a rack and pinion type. On the other hand, the driving mechanism 63 may employ various mechanisms as long as it is a mechanism that moves the moving member 61 in a sliding direction along a linear or arcuate locus. For example, as the drive mechanism 63, a mechanism that converts a rotary motion such as a ball nut type or a friction roller type into a reciprocating motion, or a linear motion mechanism such as a cylinder type may be employed.

  Further, the switching device 60 may switch between a display state and a non-display state of the feeder code 59 by opening and closing a lid member that covers the seating surface to which the feeder code 59 is attached. The switching device 60 may display the feeder code 59 as an image on the display. In such a configuration, the switching control unit 46 controls the opening / closing of the lid member and the display on the display based on the determination result by the determination unit 45, as in the embodiment.

(Determination by the determination unit 45)
In the embodiment, when the reel code 82 is read and the type of electronic component is input, the determination unit 45 determines that the feeder code 59 needs to be read (S11: Yes). On the other hand, the determination unit 45 may determine that it is necessary to read the feeder code 59 when the type of the electronic component is directly input by the operator.

  In addition to the registration process, the determination unit 45 is accompanied by the replenishment of the electronic component when the remaining amount of the electronic component loaded in the feeder 50 becomes less than the prescribed amount during the execution of the mounting process. It may be determined that the feeder code 59 needs to be read. The remaining amount of electronic components is determined based on, for example, detection of the end of the carrier tape 81 loaded in the feeder 50 and the operation amount of the feeding operation. Specifically, the end of the carrier tape 81 is detected by a sensor arranged at a predetermined position in the transport path, and the remaining amount of the electronic component is estimated based on the operation amount of the first sprocket 53 after the detection.

  According to such a configuration, the control device 40 notifies the operator to replenish electronic components by switching the feeder code 59 to the display state, and also notifies any one of the plurality of feeders 50 of the electronic device. It is possible to indicate whether parts should be replenished. Thus, the operator can find the feeder 50 in which the feeder code 59 is displayed by the switching device 60, recognize that the electronic component needs to be replenished, and perform a registration process executed at the time of replenishment. It can be done easily.

(Other variations)
In the embodiment, the feeder 50 is an autoloading type tape feeder. On the other hand, the feeder 50 may be configured to be a general-purpose type or a splicing type tape feeder that does not have a feeding mechanism in the insertion portion Di. In addition to the tape type, the feeder 50 may be configured as a stick feeder adopting a stick type or a bulk feeder adopting a bulk type.

  Moreover, in embodiment, the aspect with which the control apparatus for feeders was integrated in the control apparatus 40 of the electronic component mounting machine 1 was illustrated. On the other hand, the feeder control device may be incorporated in an external device of the electronic component mounting machine 1. Specifically, the feeder control device is assumed to be incorporated in a management device that performs calibration and maintenance of the feeder 50, a loading device that loads the carrier tape 81, the feeder control unit 58 of the feeder 50, and the like.
