Description

  The present invention relates to a feeder control device and control method capable of suppressing power consumption required for driving a tape feeder, and a component supply device.

  The component feeder of many component mounting apparatuses is composed of a plurality of tape feeders.In a conventional tape feeder, a tape feed mechanism is used only while an operator operates an operation button provided on the tape feeder. In operation, the carrier tape accommodated in the tape feeder is fed and driven.

  Therefore, it is physically unlikely that the tape feed mechanisms of a plurality of tape feeders are operated at the same time. For this reason, the tape feeders operating at the same time are operated so that the maximum current consumption that would cause the fuse to be blown to the control board does not flow. The number is limited to a specified number, thereby preventing disconnection of the fuse and suppressing power consumption.

  On the other hand, for example, in an improved tape feeder described in Patent Document 1, that is, an automatic loading feeder, when an operator inserts a carrier tape into a tape insertion slot, the carrier tape is automatically loaded to a predetermined position. . In addition, the auto-loading feeder has an automatic tape discharging function in which once the operator operates the operation button, the tape feeding mechanism keeps operating until the tape feeder is discharged to the tape insertion slot.

WO 2015/029122

  As described above, in the improved tape feeder, the operation button only needs to be operated once, so that the tape feed mechanisms of a plurality of tape feeders can be operated at the same time. For this reason, the power consumption of the tape feeder increases, and the possibility that the fuse is disconnected increases.

  The present invention has been made in view of the above-described problem, and detects whether a tape feeding mechanism of a tape feeder is operating at the same time, and when a specified number of tape feeders are in an operating state, the state is set to a non-operating state. It is an object of the present invention to provide a feeder control device, a control method, and a component supply device that suppress the operation of an input operation unit of a certain tape feeder even when the input operation unit is operated.

  In order to solve the above problem, a feeder control device of the present invention controls a tape feeder provided with a tape feed mechanism that conveys a carrier tape along a conveyance path based on an operation of an input operation unit by an operator. A detection unit that detects that the tape feed mechanisms of the plurality of tape feeders mounted on the component supply device are simultaneously operating, and the detection unit has a predetermined number of the tapes set in advance. If it is detected that the tape feed mechanism of the feeder is simultaneously operating, the tape feeder of the tape feeder is operated even when the input operation unit of the tape feeder whose tape feed mechanism is inactive is operated. It is characterized in that the operation of the mechanism is suppressed.

  According to the present invention, it is detected that the tape feed mechanism of the tape feeder is in the operating state at the same time, and when the specified number of tape feed mechanisms are in the operating state, the tape feed mechanism of the tape feeder in the non-operating state is detected. Since the operation of the tape feed mechanism of the tape feeder is suppressed even when the input operation unit is operated, disconnection of the fuse can be suppressed and power consumption can be suppressed.

The control device 20 controls the component mounting operation according to a mounting sequence programmed in advance.

  The plurality of tape feeders 21 are removably mounted side by side in the X-axis direction on a plurality of slots 23 a formed in the pallet table 23 on the machine base 41. When the tape feeder 21 is mounted in the slot 23a, a connector (not shown) provided on the front side of the tape feeder 21 is connected to a connector (not shown) provided on the pallet table 23 side, and the component mounting apparatus 10 is connected via both connectors. Power is supplied to the tape feeder 21 from the side, and necessary information can be communicated between the tape feeder 21 and the component mounting apparatus 10. At the rear of each tape feeder 21, a tape reel 22 around which a carrier tape is wound is detachably mounted. The detailed configuration of the tape feeder 21 will be described later.

  As shown in FIG. 2, the carrier tape 100 is formed by forming component storage portions 100a for storing components Pa such as a large number of electronic components with a constant interval in the longitudinal direction of the tape. On the upper surface of the carrier tape 100, a cover tape 100b for closing the component storage portion 100a is attached. At one side of the carrier tape 100, feed holes 100c are penetrated at regular intervals in the longitudinal direction of the tape, and a sprocket described later is engaged with the feed holes 100c to feed and drive the carrier tape 100.

  Next, the configuration of the tape feeder 21 will be described with reference to FIGS. The tape feeder 21 mainly includes a feeder body 21b, a first motor 25 and a second motor 26, a tape insertion recognition lever 51, a first sprocket 61 and a second sprocket 62 as front sprockets, and a second sprocket as rear sprockets. It comprises a 3 sprocket 63 and a fourth sprocket 64, a tape transport rail 38 as a transport path, a control unit 39, a cover tape peeling device 70, and the like. As will be described later, the tape feeder 21 can automatically convey the carrier tape 100 inserted into the tape insertion slot 21d to the component suction position 21a where the component is sucked, and automatically transfers the carrier tape 100 to the tape insertion slot 21d. It is configured to be able to be discharged. 3 and 4, the side wall of the feeder main body 21b is removed so that the internal structure of the tape feeder 21 can be visually recognized.

  The tape transport rail 38 guides the transport of the carrier tape 100, and is disposed from a tape insertion port 21d provided at a rear part of the feeder main body 21b to a front part suction position 21a. A first sprocket 61 and a second sprocket 62 that can engage with the feed hole 100c of the carrier tape 100 are rotatably provided below the front part of the tape transport rail 38. A third sprocket 63 and a fourth sprocket 64 that can be engaged with the feed hole 100c of the carrier tape 100 are rotatably provided below the rear portion of the tape transport rail 38. The tape transport rail 38 is provided with window holes (not shown) so that the sprockets 61 to 64 can engage with the carrier tape 100 transported on the tape transport rail 38.

  The first motor 25 rotates the first sprocket 61 and the second sprocket 62, and the rotating shaft 25a of the first motor 25 is connected to the first sprocket 61 and the second sprocket 62 via a required gear mechanism 27. Have been. The second motor 26 rotates the third sprocket 63 and the fourth sprocket 64, and the rotating shaft 26a of the second motor 26 is connected to the third sprocket 63 and the fourth sprocket 64 via a required gear mechanism 28. Have been. The first and second motors 25 and 26 and the first to fourth sprockets 61 to 64 constitute a tape feeding mechanism 30 for transporting the carrier tape 100 along the tape transport rail 38.

  The entrance holding member 32 is arranged along the rear upper surface of the tape transport rail 38 in the vicinity of the tape insertion opening 21d, and is provided to be vertically movable so as to be able to approach and separate from the tape transport rail 38. The inlet pressing member 32 is pressed downward by the spring 35-2, and is normally in contact with the upper surface of the tape transport rail 38. The downstream holding member 33 holds the carrier tape 100 on the downstream side of the entrance holding member 32, and is provided to be vertically movable so as to be able to approach and separate from the tape transport rail 38. The downstream holding member 33 is pressed downward by the spring 35-1 and is normally in contact with the upper surface of the tape transport rail 38.

  As shown in FIG. 4, a tape insertion recognition lever 51 has a front portion supported by a pivot 52 at a rear portion of the feeder body 21b, and is rotatable. At the center of the tape insertion recognition lever 51, an operation engagement portion 51 a that engages with the lower surface of the engagement member 54 provided on the entrance holding member 32 is formed. The tape insertion recognition lever 51 is rotated counterclockwise in FIG. 4 by the urging force of the spring 55, and normally holds the operation engagement portion 51a at the lowered position, and moves the entrance holding member 32 by the spring 35-2. It is brought into contact with the tape transport rail 38 by the urging force. Thus, the tape insertion port 21d is normally closed by the baffle plate 56 pivotally supported at the rear portion of the entrance holding member 32, so that the carrier tape 100 cannot be inserted through the tape insertion port 21d.

  On the other hand, when the operation knob 51b provided at the rear end of the tape insertion recognition lever 51 is lifted by the operator and the tape insertion recognition lever 51 is rotated against the urging force of the spring 55, the operation engagement is started. The inlet pressing member 32 is raised by the portion 51a against the urging force of the spring 35-2. As a result, the entrance holding member 32 is separated from the tape transport rail 38, the tape insertion opening 21d is opened, and the insertion of the carrier tape 100 becomes possible.

  The stopper member 31 is provided adjacent to the downstream side of the entrance pressing member 32. The stopper member 31 is rotatable with a shaft support 31 a provided at an intermediate portion thereof being supported by a downstream holding member 33.

  At the front of the tape insertion recognition lever 51, there is formed an operating portion 51c which can be engaged with an engagement portion 31e provided at the front of the stopper member 31, and the tape insertion recognition lever 51 resists the urging force of the spring 55. When rotated, the engaging portion 31e of the stopper member 31 is engaged with the operating portion 51c. As a result, the stopper member 31 is rotated counterclockwise in FIG. 4 around the shaft support 31a against the urging force of a spring (not shown), and the rear end of the stopper member 31 abuts on the tape transport rail 38. Let it. The rear end of the stopper member 31 is separated from the tape transport rail 38 so that the carrier tape 100 can be normally inserted.

  Next, the operation of the tape feeder 21 will be described. Normally, the tape insertion recognition lever 51 is held in the state shown in FIGS. 3 and 4 by the urging force of the spring 55, and the entrance pressing member 32 is in contact with the tape transport rail 38 and the baffle plate 56 The tape insertion opening 21d is closed.

  In this state, when the operation knob 51b of the tape insertion recognition lever 51 is lifted by the operator, the entrance pressing member 32 is separated from the tape transport rail 38 via the operation engaging portion 51a. As a result, the tape insertion slot 21d is opened, and the carrier tape 100 can be inserted. In this state, the operator inserts the carrier tape 100 from the tape insertion slot 21d onto the tape transport rail 38, and inserts the carrier tape 100 to a predetermined position where the carrier tape 100 contacts the rear end of the stopper member 31. The sprocket hole 100c is engaged with the fourth sprocket 64.

  When the carrier tape 100 is inserted to a predetermined position and the tape insertion recognition lever 51 is returned to the original position, the first and second motors 25 and 26 of the tape feed mechanism 30 are driven, and the first to fourth sprockets are driven. 61 to 64 are rotated. As a result, the carrier tape 100 engaged with the fourth sprocket 64 is conveyed to the third sprocket 63 side.

  By the transport of the carrier tape 100 by the fourth sprocket 64, the downstream pressing member 33 is lifted by the carrier tape 100 against the urging force of the spring 35-1, and the carrier tape 100 is moved to the downstream pressing member 33 and the tape transport rail. 38. When the feed hole 100c of the carrier tape 100 conveyed by the fourth sprocket 64 engages with the third sprocket 63, the carrier tape 100 is conveyed by the third sprocket 63 to the second sprocket 62 side.

  When the feed hole 100c formed in the carrier tape 100 is engaged with the second sprocket 62, the carrier tape 100 is sent to the cover tape peeling device 70 by the second sprocket 62, and the carrier tape 100 is placed on the upper surface of the carrier tape 100 by the cover tape peeling device 70. The attached cover tape 100b is peeled off. When the feed hole 100c of the carrier tape 100 engages with the first sprocket 61, the components stored in the carrier tape 100 are sequentially transported to the component suction position 21a, and at the component suction position 21a, the suction nozzle 46 of the component mounting device 14 is moved. Is adsorbed.

  When the carrier tape 100 is being conveyed by the tape feeder 21, the carrier tape 100 pushes up the front end of the stopper member 31 to rotate the stopper member 31, and the rear end of the stopper member 31 It contacts the upper surface of the carrier tape 100.

  Therefore, in this state, as described above, the tape insertion recognition lever 51 is rotated to move the subsequent carrier tape 100 from the upper surface of the preceding carrier tape 100 and the entrance pressing member 32 through the tape insertion slot 21d. When inserted between them, the leading end of the subsequent carrier tape 100 contacts the rear end of the stopper member 31 and stops at that position. Therefore, further conveyance of the subsequent carrier tape 100 is prevented, and the subsequent carrier tape 100 waits at that position.

  An operation panel 71 shown in FIG. 5 is provided on the upper surface of the rear end of the tape feeder 21. The operation panel 71 is provided with an input operation unit 73 including operation buttons, a changeover switch 75, and a display unit 77 including LEDs.

  The input operation unit 73 includes three operation buttons 73a to 73c. When the first operation button 73a is operated, the motors 25 and 26 of the tape feed mechanism 30 are driven to rotate forward, and the carrier tape 100 is driven to be driven. You. When the second operation button 73b is operated, the origins of the rotational positions of the sprockets 61 and 62 are adjusted, and the error of the feed amount of the carrier tape 100 is eliminated. When the third operation button 73c is operated, the motors 25 and 26 of the tape feed mechanism 30 are driven to rotate in the reverse direction, and the carrier tape 100 is pulled back.

  Once the third operation button 73c is operated by the operator, the rotation of the tape feed mechanism 30 in the other direction of the motors 25 and 26 is continued, and the carrier tape 100 is retracted to a predetermined position. That is, the carrier tape 100 is automatically ejected to the tape insertion slot 21d.

  The changeover switch 75 is composed of three changeover switches 75a to 75c, and the first changeover switch 75a is a switch for changing the level of the feeding speed of the carrier tape 100. The second changeover switch 75b is a switch for setting the type of the carrier tape 100 to either embossed tape or paper tape. The third changeover switch 75c is a switch that selects the feed pitch of the carrier tape 100 according to the arrangement pitch of the component storage units 100a.

  The display unit 77 includes three-color LEDs (display lamps). The green LED 77a, the orange LED 77b, and the red LED 77c can take a lighting state, a blinking state, and a light-off state independently of each other.

  As a main function of the display unit 77, the green LED 77a is turned on when the power of the tape feeder 21 is turned on and is turned off when the power is turned off. The orange LED 77b is turned on when the tape feeder 21 has a “device abnormality”. Further, the red LED 77c is lit when an operation instruction is provided by operating the third operation button 73c of the input operation unit 73 and the specified number of tape feeders 21 have already been operated. Thereby, the operator can be notified that the tape feeder 21 cannot operate in the operation waiting state.

  FIG. 6 shows a control block for controlling the tape feeder 21. A pallet control board 90 is provided between the control unit 20 for controlling the component mounting apparatus 10 and the control unit 39 of the tape feeder 21. . The pallet control board 90 recognizes whether the tape feed mechanism 30 of each tape feeder 21 is operating (automatic ejection of tape) or is stopped based on the tape feed mechanism operation IO signal from the control unit 39. A detection unit 92 for detecting the number of operating tape feed mechanisms 30 during operation is provided. Then, when the number of operating tape feeders 21 detected by the detecting unit 92 reaches the preset specified number K0, the pallet control board 90 controls all of the tape feeders 21 except the operating tape feeders 21. It has a function to restrict (suppress) the operation.

  On the other hand, the control unit 39 of the tape feeder 21 whose operation is restricted includes a storage unit 94 that stores the operation content input from the input operation unit 73 during the operation restriction. The operation content stored in the storage unit 94 is in an operation waiting state until the number of operating tape feeding mechanisms 30 in operation becomes less than the specified number.

  FIG. 7 is a flowchart showing the interlock processing by the pallet control board 90. Hereinafter, an example in which the specified number K0 of the tape feeders 21 that can be operated simultaneously is limited to three will be described.

  In step S102, N is reset to 0 (zero). N indicates the total number of slots 23a in which the tape feeders 21 are mounted. Next, in step S104, it is determined whether the number K1 of operation of the tape feeder 21 detected by the detection unit 92 is smaller than the specified number K0. If the number of operations K1 of the tape feeder 21 is smaller than the specified number K0 (if the determination result is YES), the process proceeds to step S106, and if the number of operations K1 has reached the specified number K0 (the determination result is NO). If so, the process proceeds to step S108.

  In step S106, the interlock release of the tape feeder 21 having the slot number "N" is output, and in the following step S110, the slot number is incremented by "1" so that N = N + 1. Then, in step S112, It is determined whether or not N has reached the maximum value Nmax (maximum number of tape feeders) of the slot number.

  If the decision result in the step S112 is YES (N ≧ Nmax), in a succeeding step S114, N is reset to 0, and the program is returned. On the other hand, if the decision result in the step S112 is NO, the process returns to the step S104, and the above steps are repeated.

  On the other hand, when the operation number K1 of the tape feeder 21 reaches the specified number K0 (three) and proceeds to step S108, in step S108, all the tapes except the three tape feeders 21 in which the tape feeding mechanism 30 is operating are operated. An interlock command is output to the feeder 21. As described later, even if the third operation button 73c of the input operation unit 73 of the tape feeder 21 except for the three tape feeders 21 in operation is operated by the interlock command, the operation of the tape feed mechanism 30 is performed. Is suppressed.

  In this manner, the interlock release of each tape feeder 21 is output until the operation number K1 of the tape feed mechanism 30 of the tape feeder 21 reaches the specified number K0, and the input operation unit 73 of any of the tape feeders 21 is output. The tape feed mechanism 30 can be operated even when the third operation button 73c is operated, and when the operation number K1 of the tape feed mechanism 30 reaches the specified number K0, the operating tape feeder 21 (tape feed mechanism 30) is operated. The further operation of the tape feed mechanism 30 is suppressed by an interlock command to each of the tape feeders 21 excluding.

  FIG. 8 is a flowchart showing a control process of the tape feeder 21 by the control unit 39. The control process is sequentially executed at predetermined time intervals by the control unit 39 of each tape feeder 21.

  First, in step S202, the control unit 39 checks the interlock state from the pallet control board 90, and if it determines that the interlock command is being issued, proceeds to step S204. Proceed to S210. In step S204, it is determined whether or not an operation instruction has been made by operating the third operation button 73c of the input operation unit 73. If it is determined in step S204 that an operation instruction has been issued (if the determination result is YES), the process proceeds to step S206.

  In this case, since the tape feeder 21 for which the operation instruction is given by the operation of the input operation unit 73 is in the interlock command, the LED 77c of the display unit 77 of the tape feeder 21 whose input operation unit 73 is operated in step S206. Is turned on, and the operator is informed that the operation number K1 has reached the specified number K0 and cannot operate.

  Further, in this case, the operation waits until the number of operating tape feeders 21 (tape feeding mechanism 30) becomes less than the specified number K0. In step S204, when it is determined that there is no operation instruction (when the determination result is NO), the program returns.

  On the other hand, in step S210, the control unit 39 determines whether or not it is in the waiting state based on the content stored in the storage unit 94. If it is determined that the vehicle is waiting for a turn (if the determination result is YES), the control unit 39 outputs a tape feed mechanism operation IO signal to the pallet control board 90 in step S212. In the following step S214, the control unit 39 starts the operation of the tape feed mechanism 30 of the tape feeder 21, and then in step S216, the control unit 39 waits for the turn of the tape feeder 21 that started the operation of the tape feed mechanism 30. The state is released, and the lighting of the LED 77c of the display unit 77 is released (turned off).

  When there are a plurality of tape feeders 21 in the waiting state, the operation of the tape feeding mechanism 30 is started in the order of the waiting order, or the operation of the tape feeding mechanism 30 is started in the order of the smaller slot number. I just need.

  In this way, the tape feed mechanism 30 of the tape feeder 21 in the standby state is operated, the carrier tape 100 loaded in the tape feeder 21 is retracted toward the tape insertion slot 21d, and the carrier tape 100 is automatically ejected. You. When the carrier tape 100 is ejected to a predetermined position, the operation of the tape feed mechanism 30 is stopped.

  On the other hand, if it is determined in step S210 that the tape feeder 21 is not waiting for a turn (if the determination result is NO), the process proceeds to step S220, where the third operation button of the input operation unit 73 is determined. It is determined whether or not an operation instruction has been given by the operation of 73c. If it is determined that an instruction has been given (if the determination result is YES), the process proceeds to step S222, where the tape feeder 21 on which the input operation unit 73 has been operated is operated. Is output to the pallet control board 90. Next, in step S224, the operation of the tape feed mechanism 30 of the tape feeder 21 is started.

  In step S220, when it is determined that there is no operation instruction (when the determination result is NO), the program returns.

  In the above-described embodiment, it is detected that the tape feeding mechanisms 30 of the plurality of tape feeders 21 mounted on the component supply device 11 are simultaneously operating, and the tape feeding of the predetermined number of tape feeders 21 is performed. If it is detected that the mechanism 30 is operating at the same time, the operation of the tape feeding mechanism 30 of the tape feeder 21 is operated even if the input operation unit 73 of the tape feeder 21 in which the tape feeding mechanism 30 is not operating is operated. Suppress.

  This limits the simultaneous operation of the tape feed mechanisms 30 of the specified number or more of the tape feeders 21, so that the disconnection of the fuse can be suppressed and the power consumption can be reduced. Can be obtained.

  In the above-described embodiment, the component supply device 11 includes a detection unit 92 that detects that the tape feed mechanism 30 of the tape feeder 21 is in an operating state, and a detection unit 92 that includes a predetermined number of tape feeders. If the tape feed mechanism 30 of the tape feeder 21 detects that the tape feed mechanism 30 is in the operating state at the same time, the input operation unit 73 of the tape feeder 21 in which the tape feed mechanism 30 is in the inactive state is operated. A control unit 39 for suppressing the operation of the mechanism 30.

  This limits the simultaneous operation of the tape feed mechanisms 30 of the tape feeders 21 of the specified number or more, so that it is possible to obtain the component supply device 11 that can suppress the disconnection of the fuse and the power consumption. .

  In the above-described embodiment, the display unit 77 that indicates that the control unit 39 has suppressed the operation of the tape feed mechanism 30 is provided on the tape feeder 21, and the display on the display unit 77 allows the operator to specify the specified number of tape feeders. 21 can be easily recognized as being in the operating state.

  In the above-described embodiment, when the input operation unit 73 is operated during the operation of the tape feed mechanism 30 of the specified number of tape feeders 21, the tape feed of the tape feeder 21 operated by the input operation unit 73 is performed. When the mechanism 30 is in the waiting state and the number of the operating tape feeding mechanisms 30 becomes less than the specified number, the waiting state is released and the tape feeding mechanism 30 is automatically operated. When the input operation unit 73 is operated during the operation of the tape feed mechanism 30, only the display unit 77 may be turned on to notify the operator.

  Further, in the above-described embodiment, an example has been described in which the tape feeder 21 is configured to keep the tape feeding mechanism 30 operated until the carrier tape 100 is ejected by operating the input operation unit 73. The present invention employs a second conventional tape feeder 121 (hereinafter, referred to as a second tape feeder 21 to distinguish it from the conventional tape feeder 21 in which the tape feed mechanism 30 can operate only while the input operation unit 73 is operated). ) Can be applied to a component that is removably mounted in the slot 23a of the component supply device 11 in a mixed manner.

  That is, as shown in FIG. 9, the tape feed mechanism 30 of the second tape feeder 121 includes one motor 125 that rotates a sprocket 128 that can be engaged with the carrier tape 100 on the component suction position 121a side. Then, the motor 125 of the tape feed mechanism 30 is driven only while the input operation unit of the operation panel 171 provided on the second tape feeder 121 is operated, and feeds and drives the carrier tape 100. In the figure, reference numeral 122 denotes a tape reel, and 139 denotes a control unit.

  Since the motor 125 of the tape feed mechanism 30 is driven only while the input operation unit is operated, the second tape feeder 121 operates the tape feed mechanisms 30 of the tape feeders 21 and 121 by a specified number. During operation, even if the input operation unit of the second tape feeder 121 is operated, the second tape feeder 121 cannot be put into the operation waiting state. For this reason, when the input operation unit of the second tape feeder 121 is operated while the tape feed mechanism 30 is being operated by the specified number, the LED 77c of the display unit 77 is blinked or the like to inform the operator of the specified number. It is good to notify that the tape feeder 21 is in the operating state and to prompt the user to operate the operation button again.

  In the above-described embodiment, an example has been described in which an operation instruction is given to the tape feeding mechanism 30 by operating the input operation unit 73 including operation buttons.
