Power and control signals are transmitted from the electrical component 57 to the electrical components on the frame 59 side (first and second motors 81 and 91) via the.

[0050] The electrical component 57 is also coupled to the tape storage box 200. In other words, the electrical component 57 is detachably attached to the lower side of the frame 59 and the tape storage box 200 that are connected to each other in the front-and-rear direction, and a part of the electrical component 57 is accommodated in the tape via the screw member 232. Connected to box 200. Specifically, the screw member 232 passes through the through-hole 243 formed in the upper wall portion 240 and is screwed into the screw groove 218 formed in the lower portion of the tape storage box 200. 57 is mounted on both sides of the frame 59 and the tape storage box 200 across the boundary.

 [0051] As described above, in the component supply device 50 of the present embodiment, since the storage capacity of the tape storage box 200 can be changed, the size of the tape storage box 200 is set to a high degree of freedom in accordance with the use situation. become able to.

 [0052] In particular, since the storage volume of the tape storage box 200 changes according to the increase in the storage capacity of the cover tape CV stored in the tape storage box 200, the tape storage box 200 is stored when the storage capacity of the cover tape CV is small. When the box 200 becomes compact and the storage capacity increases, the storage capacity of the tape storage box 200 can be expanded to properly hold a large amount of cover tape CV.

 The tape storage box 200 includes a first case part 210 and a second case part 220 that can move relative to the first case part 210. In this way, the storage volume of the tape storage box 200 can be easily changed with a simple configuration in which the second case portion 220 is simply moved relative to the first case portion 210.

 [0054] The first case part 210 has a box shape in which an opening 208 is formed at least in part, and the second case part 220 is slidable in a predetermined direction through the opening 208. Yes. In this way, the storage capacity of the tape storage box 200 can be expanded or reduced more smoothly.

[0055] In addition, the first case portion 210 has an introduction port 207 for introducing the cover tape CV at one end in the sliding direction of the second case portion 220, and corresponds to the other side in the sliding direction. The opening 208 is provided at the end. In this way, as the cover tape CV is sequentially fed from the introduction port 207 side to the opening 208 side, the second case portion 220 pushed out by the force bar tape CV smoothly passes through the opening 208 to the first case. It moves to the outside of the part 210. Therefore, the capacity of the tape storage box 200 can be expanded smoothly and automatically as the capacity of the cover tape CV increases. [0056] In this embodiment, since the tape storage box 200 is detachably attached to the frame 59 holding the delivery device 80 and the peeling device 90, the tape storage box 200 or the frame 59 side If one of the parts (that is, the delivery device 80 or the peeling device 90) is defective (for example, damaged), only one of the components can be repaired or replaced. It becomes the structure excellent in property.

 [0057] In addition, since the electrical component 57 is detachably attached to the frame 59 holding the delivery device 80 and the peeling device 90, the components on the frame 59 side or the electrical component 57! / In the event that a defect occurs in one of them, the ability to repair, replace, etc. only one of the defects can be improved, resulting in a configuration with excellent maintainability and economy.

 That is, according to the above configuration, the parts on the frame 59 side, the electrical component 57, and the tape storage box 200 can be repaired and replaced independently, which is further advantageous in terms of cost and maintenance. It has become.

 [0059] Further, since the frame 59 is made of a metal material and the tape storage box 200 is made of a resin material, the frame 59 can be secured with rigidity, and the tape storage box 200 is connected to the tape storage box 200! /, Can be reduced in weight.

 [0060] <Embodiment 2>

 Next, Embodiment 2 will be described. FIG. 13 and FIG. 14 are diagrams showing a tape storage box used in the component supply device of the second embodiment. In these drawings, the same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The same applies to other embodiments described later.

As shown in FIGS. 13 and 14, a holding means 260 is provided in the tape storage box 200. The holding means 260 is configured to hold the second case part 220 at a predetermined position and to release the holding when a pressing force is applied to the second case part 220 in the direction of expanding the accommodation volume. It has become. Specifically, the holding means 260 is configured by the metal plate 262 and the magnet 261, and when the cover tape CV is not stored in the case storage box 200, the second case section 220 is The magnet 261 is attracted to the metal plate 262 and is held at a predetermined position shown in FIG. On the other hand, the cover tape CV accumulates sequentially in the case storage box 200, and the second case part 2 by the cover tape CV 2 When the force pushing 20 overcomes the attractive force of the magnet 261, the holding is released as shown in FIG. 14, and the second case portion 220 slides backward.

 Further, as shown in FIGS. 13 and 14, a sensor 270 that outputs a detection signal corresponding to the amount of the cover tape CV in the tape storage box 200 is provided in the tape storage box 200, and the sensor A display section LP (corresponding to an example of the notification means according to the present invention) that performs notification according to the detection signal from 270 is provided.

 [0063] The sensor 270 is configured as a pressure sensor, and outputs a detection signal when the capacity of the cover tape CV reaches a certain level and the force of pressing the sensor 270 by the cover tape CV exceeds a predetermined value. It has become. The control unit 250 is constituted by a CPU or the like, acquires a detection signal from the sensor 270, and outputs a drive signal to the display unit LP.

[0064] The display unit LP is configured by, for example, an LED, and is configured to emit light in response to a drive signal from the control unit 250. In FIG. 14, the controller 250 and the signal path are not shown. In any case, when the force pressing the sensor 270 by the cover tape CV exceeds a predetermined value, the display unit LP emits light.

 In the present embodiment, the second case portion 220 is held at a predetermined position, and the holding is released when a pressing force is applied to the second case portion 220 in the direction of expanding the accommodation volume. Since the holding means 260 is provided, the tape storage box 200 is appropriately maintained at a predetermined storage volume when the storage capacity of the cover tape CV is not so large, and the structure is strong against vibrations. On the other hand, when the capacity of the cover tape CV increases and the pressing force applied to the second case part 220 by the cover tape CV increases to such an extent that the holding is released, the storage volume starts to expand. Therefore, it is possible to prevent inappropriate expansion of the accommodation volume due to vibrations and the like, and to appropriately notify the outside that the cover tape CV is accumulated to some extent.

[0066] In addition, a sensor 270 that outputs a detection signal corresponding to the amount of cover tape CV stored in the tape storage box 200, and a display unit LP (notification means) that performs notification according to the detection signal from the sensor 270 are provided. I have. Therefore, an operator or the like related to the component supply device 50 can manage the tape storage box 200 easily and appropriately based on the notification. <Embodiment 3>

 Next, Embodiment 3 will be described. FIG. 15 shows a tape storage box used in the component supply apparatus of Embodiment 2, and FIG. 16 shows an example of a tape storage box different from FIG. The third embodiment is different from the first embodiment in that the outer wall surface of the second case portion 220 is configured differently from the first embodiment, and the other configuration is basically the same as the first embodiment. In the tape storage box 200 of the present embodiment, the shape, pattern, color or combination of the outer wall surface of the second case portion 220 is made different from the outer wall surface of the first case portion 210 so as to stand out. Yes.

 In the configuration of FIG. 15, the outer wall surface force of the second case part 220 is different in color from the outer wall surface of the first case part 210, and the storage volume of the tape storage box 200 is minimized. At least a part of the outer wall surface of the second case portion is covered with the first case portion. As the second case part 220 moves relative to the first case part 210, the amount of exposure to the outside of the outer wall surface of the second case part 220 changes.

 More specifically, as shown in FIG. 15, the outer wall surfaces of the opposing wall portions 223 and 224 of the second case portion 220 (in FIG. 15, the outer wall surface 224B of the one opposing wall portion 224 is shown) The color is different from the outer wall surface of the side wall portion 215, 216 (see FIG. 5) of the case portion 210 (see, for example, fluorescent color), and this is different when the capacity of the tape storage box 200 is minimized. The entire outer wall surface 224B to be colored is covered with the first case portion 210, and the outer wall surface 224B of the second case portion 220 is moved as the second case portion 220 moves relative to the first case portion 210. The amount of exposure to the outside changes.

 In this way, the operator's equal force S related to the component supply device 50 and the outer wall surface of the second case part 220 can be easily grasped, and based on the exposure amount of the outer wall surface of the second case part 220. Thus, the state of the case storage box 200 can be recognized well.

Also, in the configuration of FIG. 16, a predetermined notification mark 280 is attached to the outer wall surface of the second case portion 220, and the notification mark 280 is disposed in the first case portion 210. The second case portion 220 is configured such that the notification mark 280 is displaced from the second position arranged outside the first case 210 portion. The notice mark 280 in FIG. 16 is configured as a comment that conveys that the collection time of the cover tape CV has arrived. In a state where the storage volume is minimized, the notification mark 280 is covered with the first case portion 210 and thus cannot be visually recognized. When the sliding amount of the second case portion 220 exceeds a predetermined amount, the notification mark 280 is displayed as shown in FIG. It becomes visible!

 In this way, it is possible to easily recognize from the outside the force that the second case part 220 is in the first position or the second position. Accordingly, the position of the second case portion 220 can be properly grasped based on the operator's isotropic force S and the notification mark 280 related to the component supply device 50, and the state of the case storage box 200 can be determined. It will be possible to recognize well. In particular, when the slide amount of the second case part 220 exceeds a predetermined amount, it is possible to notify the worker that the collection time has come, so that the worker can appropriately know the collection time and facilitate maintenance. It can be carried out.

 <Embodiment 4>

 Next, Embodiment 4 will be described. FIGS. 17 and 18 are views showing a tape storage box used in the component supply device of the fourth embodiment. The present embodiment is different from the second embodiment in that the tape storage box can be driven by the actuator 400 and that the display unit LP is omitted. Other points are the same as in the second embodiment.

 In the present embodiment, as in the second embodiment, a sensor 270 that outputs a detection signal corresponding to an increase in the amount of cover tape CV stored in the tape storage box 200 is provided. The sensor 270 has the same configuration as that of the first embodiment and is configured as a pressure sensor. When the capacity of the cover tape CV reaches a certain level and the force pressing the sensor 270 by the cover tape CV exceeds a predetermined value, the detection signal Is output. The control unit 290 (corresponding to the actuator control means according to the present invention) is constituted by a CPU or the like, acquires a detection signal from the sensor 270, and outputs a signal for driving the actuator 400. The actuator 400 is for displacing the second case part 220, and here is configured as an air cylinder.

Specifically, when a drive signal for driving the actuator 400 is output from the control unit 290, the actuator 400 is driven via a drive circuit (not shown), and the drive shaft 402 is drawn into the cylinder unit 401. Accordingly, the second case portion 220 connected to the drive shaft 402 slides as shown in FIG. In this way, the detection signal from sensor 270 Accordingly, the control unit 290 controls the driving of the vector 400 that displaces the second case unit 220 in the direction of increasing the accommodation volume. If no detection signal is output from the sensor 270, the actuator 400 is maintained in the state shown in FIG. In any case, when the force pressing the sensor 270 by the cover tape CV exceeds a predetermined value, the second case part 220 slides automatically.

 [0076] According to the configuration of the present embodiment, the second case portion 220 is automatically displaced in accordance with the increase in the amount of cover tape CV accommodated, and the capacity of the tape container 200 is increased. Accordingly, it is possible to reduce the burden on the operator and the like related to the component supply device 50, and it is possible to increase the accommodation volume more efficiently. Further, the operator can grasp the degree of the capacity of the cover tape CV! / Based on the sliding operation of the second case part 220 !.

 <Embodiment 5>

 1.Part supply device

 Next, Embodiment 5 will be described. FIG. 19 shows a component supply apparatus according to the fifth embodiment. The component supply device 50 shown in the figure has basically the same structure as that of the first embodiment, and includes a feeding device 80 for feeding the component supply tape TP, a peeling device 90 for peeling the cover tape CV, and the like. The frame 59 is configured to hold both devices, the electrical unit 57 that supplies power and outputs signals to both devices, and the tape storage box 200 that stores the cover tape CV.

In FIG. 19, reference numeral 159 denotes a tape holder. The tape holder 159 controls the protrusion of the parts by pressing the upper surface of the carrier tape CA and maintains the engagement between the carrier tape CA and the sprocket 82. Further, a slit (not shown) for folding back the cover tape CV rearward is provided at a position near the rear end of the tape holder 159.

 In the present embodiment, it is assumed that the first and second motors 81 and 91 that are driving sources of the feeding device 80 and the peeling device 90 are constituted by brushless DC motors.

[0080] Inside the electrical unit 57, a controller 300 (corresponding to the control means according to the present invention) that controls and supervises the entire component supply device 50 is accommodated. The configuration of controller 300 is shown in Fig. 20. In addition to the control device 301 that controls the first and second motors 81 and 91, the storage unit 303 and the input / output port 305 are included. On the other hand, as shown in FIG. 20, a control device 109 is provided on the surface mounting machine 10 side. This control device 109 controls the operation of each part of the surface mounter 10 in an integrated manner, and is used for various controls including the control unit 63 (FIG. 19) provided near the component supply device mounting unit 60. Consists of equipment.

 Next, a control system for controlling the second motor 91 that is a drive source of the peeling apparatus 90 will be described with reference to FIG.

 Reference numeral 311 shown in FIG. 21 is a position detection sensor. The position detection sensor 311 detects the position of the rotor magnetic pole of the second motor 91, and the output position signal Sc is input to the controller 300. The controller 300 monitors the rotation direction (forward / reverse rotation) of the second motor 91 based on the position signal Sc and also monitors the rotation speed.

 Further, reference numeral 313 is a comparison circuit, reference numeral 315 is an amplifier circuit, reference numeral 317 is a current control circuit, reference numeral 319 is a current sensor, and a feedback control system is constructed by these circuits.

More specifically, the current sensor 319 detects the motor current Im supplied to the second motor 91 and outputs a detection signal Sr having a level corresponding to the current value. Then, the output detection signal Sr is input to the comparison circuit 313.

 In comparison circuit 313, a process of comparing current command value S provided from control device 301 with detection signal Sr output from current sensor 319 is performed, and a control signal corresponding to the deviation is output. . The control signal output from the comparison circuit 313 is amplified by the amplification circuit 315 and then given to the current control circuit 317 as an operation amount.

 [0086] As a result of control (such as PWM control) being performed in the current control circuit 317 so as to reduce the deviation between the current command value S given by the control device 301 and the motor current Im, the motor of the second motor 91 The current Im is controlled to coincide with the current command value S, whereby the second motor 91 is driven with a constant torque.

In the present embodiment, the position detection sensor 311 does not employ a configuration in which a dedicated sensor such as a rotary encoder is provided, and is originally provided in the second motor 91. Substitute the V, Ru Hall element as the position detection sensor 311! Hall elements and! /, Are located inside the motor and are used to detect the rotational position of the rotor magnetic poles.

 [0088] 2. Assembly work and mounting operation

 Next, a series of assembling operations performed when the reel (not shown) around which the component supply tape TP is wound is replaced will be described. The manual assembly work performed by the workers includes the following (1) to (3).

 [0089] (1) Installation work of component supply tape

 First, when the reel is replaced, it is necessary to set the component supply tape TP on the frame 59 of the component supply device 50. For this purpose, the component supply tape TP is pulled out to a certain length from a reel not shown. Then, as shown in FIG. 22, the pulled-out leading end is drawn upward from the front portion of the frame 59 through the guide passage 56 provided in the frame 59. In this state, the cover tape CV is pulled away from the component supply tape TP, and the carrier tape CA is locked to the teeth of the sprocket 82. Thereafter, the tape holder 159 is attached. Thereby, the mounting operation of the component supply tape TP to the frame 59 is completed.

 [0090] (2) Work for fixing the component supply device to the component supply device mounting portion

 Following the mounting operation of the component supply tape TP, this time, the operation of mounting the component supply device 50 to the component supply device mounting portion 60 is performed as shown in FIG. Specifically, the operation lever 71 is manually operated to activate the lock device 70, and the component supply device 50 is fixed to the component supply device mounting portion 60. As a result, the fixing operation of the component supply device 50 is completed.

 Further, by this fixing work, the connector 58 is electrically connected to the connector 68 on the mounting machine side. As a result, the power supplied from the power supply circuit 110 (FIG. 20) of the surface mounter 10 to each electrical component (first and second motors 81 and 91) of the component supply device 50 is provided in the electrical unit 57 (not shown) Electric power is supplied through a supply circuit and the like, and the controller 300 is activated, and various control signals are input to the electrical components from the controller 109 (FIG. 20) of the surface mounter 10 through the controller 300. The

 [0092] (3) Cover tape CV setting work

When the fixing work is completed, the cover tape CV needs to be set on the peeling device 90 next. Set work by lifting the pressure roller 95 and starting from the feed roller 93. This is done by inserting the tip of the cover tape CV into the gap formed between the rollers 93 and 95 while keeping the buoyancy state. Thereafter, the pressure roller 95 is returned to the original position, so that the tip of the cover tape CV is held between the rollers 93 and 95 as shown in FIG. As a result, the setting operation is completed, and the cover tape CV can be wound up by the peeling device 90.

 [0093] From this state, when the cover tape CV is pulled to the front side of the device (in the direction of the arrow B shown in Fig. 24), as will be described below, the peeling device 90 automatically starts operating, Cover tape Take loose CV.

 [0094] (4) Cover tape slack removal work by peeling device

 Control of the peeling device 90 is performed by the controller 300 in cooperation with the control device 109 of the surface mounter 10. When the control is started, the processing of S10 and S20 shown in FIG. Is in a control state for monitoring whether or not is in the reverse rotation state. Specifically, first, in S 10, the position of the rotor magnetic pole of the second motor 91 is detected based on the position signal Sc output from the position detection sensor 311.

 Then, in the next S20, the controller 300 determines whether or not the second motor 91 is rotating in the reverse direction based on the position detection result. Both the processes of S10 and S20 are repeatedly executed until the reverse rotation of the second motor 91 is detected.

 Here, the force, which is the start time of the control of the peeling device 90 by the controller 300, is started at the same time as the controller 300 is started. Accordingly, the control of the peeling device 90 is started when the fixing operation of the component supply device 50 in (2) is completed.

 From the above, before the operator completes the set work, the controller 300 has started the processes of S10 and S20 described above (in a control state in which reverse rotation is detected).

[0098] For this reason, after the setting work of the cover tape CV in (3) is completed, the operator pulls the cover tape CV toward the front side of the apparatus, so that the pulling force is applied to the feeding roller 93 and the gear 92. When the second motor 91 is reversely rotated (rotated in the direction opposite to the take-off direction), the reverse rotation of the motor is immediately detected by the controller 300. Then, when the reverse rotation of the motor is detected in this way and the determination process of S20 is Yes, the control operation by the controller 300 shifts to the next process of S30. Become.

 [0099] In S30, a rotation command is given from the controller 300 to the control device 301 that controls the motor, whereby the second motor 91 starts rotating in the forward rotation direction. As described above, the detection of the reverse rotation of the motor is a trigger for causing the second motor 91 to start the forward rotation driving.

 From the above, in this embodiment, the position detection sensor 311 for detecting the position of the rotor magnetic pole of the second motor 91 and the second motor 91 are reversed based on the position signal Sc from the position detection sensor 311. The controller 300 that detects the rotation constitutes the setting operation detecting means of the present invention that detects that the setting operation of the cover tape CV has been performed, and the reverse of the second motor 91 as described above. The controller 300 of the present invention is configured by the controller 300 that drives the second motor 91 to rotate forward on the condition that the rotation is detected.

[0101] When the peeling device 90 is actuated by starting the second motor 91, the feed roller 93 and the pressing roller 95 are rotated, and the cover tape CV is moved to the rear side of the device (the left side in FIG. ) As a result, the cover tape CV is in a tensioned state with the slack removed, and at the same time, the second motor 91 is locked and stopped. Even in this state, the constant torque control is continued in the second motor 91. As a result, a tension equal to the set torque of the second motor 91 is applied to the cover tape CV.

 [0102] Assembling the first component supply device 50 is completed. After that, the remaining component supply device 50 may be assembled according to the same work procedure as described above.

 [0103] Then, all the component supply devices 50 subject to reel replacement have been installed in the component supply device mounting portion 60, and slack is removed from the cover tape CV of each component supply device 50. After that, each component supply device 50 performs an operation of sending the first component to the component supply position 51, and the component mounting operation can be started.

[0104] When the first part is sent to the part supply position 51, the force by which the cover tape CV is peeled off from the carrier tape CA by the operation of the peeling device 90 is applied to the second motor 91. Since the motor current is constantly supplied, the second motor 91 continuously generates a constant torque thereafter.

 Accordingly, when the cover tape CV is loosened, the second motor 91 automatically rotates to drive the feed roller 93 and the pressure roller 95 and is sandwiched between these rollers 93 and 95. Cover tape CV is fed to the rear side of the device. For this reason, when the first part reaches the part supply position 51 and the peeling device 90 stops, the cover tape CV is held in a state of being pulled toward the rear of the device (a state of being stretched without slack).

 [0106] Now, in order to start the surface mounting, a predetermined operation (for example, pressing an unillustrated start switch provided in the surface mounting machine 10) is performed. Thus, according to the following procedure, Surface mounting of components on the printed circuit board P flowing on the conveyor 20 is started.

When the predetermined operation described above is executed, the control device 109 of the surface mounter 10 operates the X-axis motor 44, the Y-axis motor 46, etc. (see FIG. 2) according to the program, so that the head unit 40 Is moved toward the component supply position 51 of each component supply device 50. Head 40 force S When the component supply position 51 is reached, the head 41 is raised and lowered, and the first component is picked up (sucked) by the head 41.

 Then, when the suction of the component by the head 41 is completed, the displacement of the suction position of the component is checked by the camera 12. Thereafter, the picked-up components are transferred by the head unit 40, and the pick-up position deviation of the components is corrected for each head 41 during the transfer. When the head 41 reaches a predetermined component mounting position on the board P, the head 41 is raised and lowered, and components are mounted on the printed board P along with the raising and lowering. As a result, the mounting of the first component is completed.

On the other hand, the control device 109 of the surface mounter 10 sends the second component to the component supply position 51 in parallel with the process of mounting the first component described above. Is executed. That is, when the pickup of the first component by the head 41 is completed, the control device 109 gives a command to the controller 300 of the component supply device 50 to start supplying the second component. In response to this, the controller 300 of each component supply device 50 issues a drive signal to the first motor 81 to operate the delivery device 80. This Then, the delivery of the component supply tape TP is started, and the second component is conveyed toward the component supply position 51.

 [0110] At this time, although the second motor 91 is in a stopped state, it receives a supply of the motor current Im and generates a predetermined torque, so that the tension in the pulling direction is continuously applied to the cover tape CV. Has been granted. Therefore, when the delivery of the component supply tape TP is started by the delivery device 80, the cover tape CV is peeled off from the carrier tape CA accordingly. When the cover tape CV becomes slack, the second motor 91 automatically rotates to remove the slack.

 [0111] Thus, once the delivery of the component supply tape TP is started, the cover tape CV is peeled off during the delivery process, so that only the carrier tape CA is sent to the front of the apparatus. Then, the peeled cover tape CV passes between the feed roller 93 and the pressure roller 95 and is sent to the tape storage box 200.

 [0112] When the delivery amount of the component supply tape TP reaches a predetermined length, the operation of the first motor 81 and eventually the delivery device 80 is stopped, and the second component is conveyed to the component supply position 51. Is completed. As a result, the mounting operation of the second component can be started.

 [0113] After that, as with the first part, the second part at the part supply position 51 is taken out by the head unit 40, and then the second part picked up is printed board. Implemented on P.

 [0114] Then, in parallel with the process of mounting this second component on the substrate P, the component supply device 5

At 0, the third part is sent to the part supply position 51.

[0115] 3. Effect

In the present embodiment, the second motor 91 is driven to rotate forward on the condition that reverse rotation of the second motor 91 is detected. With this configuration, after replacing the reel, the operator sets the cover tape CV in the peeling device 90 (that is, inserts the cover tape CV between the feed roller 93 and the pressure roller 95). However, if the cover tape CV is pulled slightly lightly after that, the second motor 91 and eventually the peeling device 90 are automatically activated to cover the cover tape. Can take cv sag. Accordingly, a slack removal start operation that is normally performed in a normal state (for example, an operation for starting driving of the second motor 91 by pressing a start switch not shown in the figure) is not required, and the time and effort can be saved.

[0116] In the present embodiment, the detection of the rotation state of the second motor 91 (detection of reverse rotation) is detected using a signal output from a Hall element built in the motor. ing. With such a configuration, it is possible to suppress an increase in the number of parts and to reduce the cost of the apparatus.

<Embodiment 6>

 Next, Embodiment 6 of the present invention will be described with reference to FIG. In the sixth embodiment, the rotation speed of the second motor 91 is monitored to detect an abnormality such as a break in the cover tape CV.

 More specifically, in the present embodiment, since the second motor 91 is controlled at a constant torque, if the motor becomes unloaded due to the breakage of the cover tape CV or the like, The rotation speed increases compared to the normal use state.

 [0119] Considering this point, the upper limit of the rotational speed of the second motor 91 observed in the normal state is set as the limit value in the present embodiment. Then, by executing the process according to the control flow described below (the process of S50 to S80 is added to the control flow of the embodiment 5), an abnormality such as breakage is detected based on the limit value. If an abnormality is detected, error handling will be performed!

 [0120] First, when the second motor 91 starts normal rotation driving in S30, the processing of S50 and S60 is subsequently executed. In the processing of S50 and S60, the rotation speed of the second motor 91 is detected based on the position signal Sc output from the position detection sensor 311, and whether or not the detected rotation speed exceeds the limit value. The determination is made by the controller 300.

 [0121] If there is an abnormality such as the cover tape CV breaking, the rotational speed increases and exceeds the limit value. As a result, No is determined when the determination process of S60 is performed, and the process corresponding to the abnormal state is taken in the subsequent processes.

[0122] First, in S70, the process of stopping the second motor 91 is executed by the controller 300. After that, in S80, for example, an error process for notifying abnormality is set in the surface mounter 10. This is executed by the processing power controller 300 and the control device 109 of the surface mounter 10 for turning on a warning light or the like outside the figure.

 [0123] With such a configuration, if there is an abnormality such as breakage of the cover tape CV, it can be detected at an early stage, which increases the reliability of the system. In addition, the configuration of the present embodiment can detect an abnormality without providing a dedicated part, and therefore has an advantage in cost compared to a configuration in which a dedicated part is provided to detect an abnormality. .

 <Embodiment 7>

 Next, Embodiment 7 of the present invention will be described with reference to FIG.

 [0125] In the previous embodiment 5, the completion of the operation of setting the cover tape CV to the peeling device 90 is detected by the reverse rotation of the second motor 91, and the second motor 91 is driven on the condition that the reverse rotation is detected. I let you. On the other hand, in the seventh embodiment, the completion of the setting operation of the cover tape CV with respect to the feeding device 80 is detected by the displacement operation of the pressing roller 95.

 More specifically, in the present embodiment, as shown in FIG. 27, a limit switch 320 is provided above the pressing roller 95! /.

 [0127] When the operator lifts up the pressing roller 95 for setting the cover tape CV on the peeling device 90, the upper part of the lifted pressing roller 95 comes into contact with the limit switch 320. As a result, the detection signal Se is output from the limit switch 320 to the controller 300. Then, the controller 300 determines that the cover tape CV is set on the peeling device 90, and a drive signal is output from the controller 300 to the second motor 91, so that the second motor 91 starts normal rotation driving. To do.

 [0128] Even with such a configuration, the same effect as in the fifth embodiment can be obtained. That is, the operator needs to manually set the cover tape CV on the peeling device 90, but after that, the second motor is operated according to the operation of the limit switch 320. The cover tape CV can be loosened by automatically starting forward rotation in 91. Therefore, the trouble of performing a dedicated operation for removing the slack of the cover tape CV can be saved.

In this example, the limit switch 320 that detects that the pressing roller 95 has been lifted, and the cover tape CV set based on the detection signal Se from the limit switch 320. The “set work detection means” of the present invention is constituted by the controller 300 that detects that the work is performed.

 <Embodiment 8>

 In the eighth embodiment, the set torque of the second motor 91 is switched according to the situation. The specific setting of the torque is as shown in FIG. 28, and the maximum torque is set immediately after the second motor 91 starts normal rotation. After that, the torque is switched to the middle level while the motor is rotating, and is switched to a small torque when stopped. The torque switching is realized by changing a current command value S given from the control device 301 to the comparison circuit 313 (see FIG. 21).

 [0131] As described above, the cover tape CV can be prevented from being broken by switching the set torque of the motor according to the situation. More specifically, a force that requires a relatively large torque at the start of the motor. Once the motor starts rotating, it is sufficient that a certain amount of tension is applied to the cover tape CV. Not needed.

 [0132] If the set torque of the second motor 91 is kept as large as that at the start of normal rotation, an excessive force is applied to the cover tape CV, particularly when the motor is stopped. There is also a risk of breakage. In this regard, with the above-described configuration, since the motor is switched to a small torque after the start of the motor, such breakage can be avoided in advance. Further, with the above configuration, the current consumption of the motor can be suppressed, which is also effective.

 [0133] The specific torque switching timing needs to be determined according to the motor rotation status. The motor rotation status is determined based on the position signal Sc from the position detection sensor 311. What is necessary is just to judge according to a rotational speed.

The set operation may be detected by detecting the entry / exit of CV).

 [0143] Finally, the configuration and effects of the present invention disclosed based on the above embodiments will be described together.

 [0144] The present invention is directed to a component supply tape that includes a carrier tape that stores components at regular intervals and a cover tape that is attached to the carrier tape so as to cover the storage component. A feeding means for feeding out, a carrier tape force by pulling the cover tape in a direction different from a feeding direction by the feeding means, a peeling means for peeling the cover tape, and the cover tape peeled by the peeling means In the component supply device including a tape storage box for storing the tape storage box, the storage capacity of the tape storage box can be changed.

 [0145] According to the present invention, the size S of the tape storage box can be set with a high degree of freedom according to the use situation.

 [0146] Further, as an embodiment of the present invention, the following configuration is preferable.

 [0147] The tape storage box may be configured such that the storage volume changes in accordance with an increase in the storage amount of the cover tape stored in the tape storage box.

In this way, the tape storage box becomes compact when the capacity of the cover tape is small, and when the capacity is large, the capacity of the tape storage box is increased to increase the capacity of the cover tape. Can be held properly.

[0149] Further, the tape storage box may have a first case portion and a second case portion that can move relative to the first case portion.

[0150] With this configuration, the storage volume of the tape storage box can be easily changed with a simple configuration in which the second case portion is simply moved relative to the first case portion.

[0151] Further, the first case portion is formed in a box shape in which an opening is formed at least in part, and the second case portion can be slid in a predetermined direction through the opening. The power S is to be completed. [0152] In this way, the storage capacity of the tape storage box can be expanded or reduced more smoothly.

 [0153] Further, the first case portion has an introduction port for introducing the cover tape into an end portion corresponding to one side in the sliding direction of the second case portion, and an end portion corresponding to the other side in the sliding direction. It can be set as the structure which has the said opening part.

 In this way, as the cover tape is sequentially fed from the inlet side to the opening side, the second case part pushed out by the cover tape smoothly passes through the opening to the outside of the first case part. To move on. Therefore, the capacity of the tape storage box can be expanded smoothly and automatically as the cover tape capacity increases.

 [0155] In addition, holding means for holding the second case portion in a predetermined position and releasing the holding when a pressing force is applied to the second case portion in a direction of expanding the accommodation volume. It can also be set as the structure provided.

 [0156] In this way, when the storage amount of the cover tape is not so large, the tape storage box is appropriately maintained at a predetermined storage volume. On the other hand, when the cover tape capacity increases and the pressing force applied to the second case portion by the cover tape increases to such an extent that the holding is released, the storage volume starts to expand. Accordingly, it is possible to prevent inappropriate expansion of the accommodation volume due to vibration or the like and to appropriately notify the outside that the cover tape is accumulated to some extent.

 [0157] In addition, a predetermined notification mark is attached to the outer wall surface of the second case portion, a first position where the notification mark is arranged in the first case portion, and the notification mark is the first position. It can be configured to be displaced at the second position arranged outside the case part.

 In this way, it is possible to easily recognize from the outside whether the second case portion is in the first position or the second position. Therefore, workers related to the parts supply device can appropriately grasp the position of the second case part based on the notification mark, and the state of the case storage box is good. Can be recognized.

[0159] In addition, the outer wall surface of the second case portion has a color different from the outer wall surface of the first case portion, and the storage volume of the tape storage box is minimized. 2 At least a part of the outer wall surface of the case part is covered with the first case part. Can do. The second case portion can be configured such that the amount of exposure to the outside of the outer wall surface of the second case portion changes as the second case portion moves relative to the first case portion.

 [0160] By doing this, it becomes easier for workers involved in the component supply device to grasp the outer wall surface of the second case portion, and the case storage box based on the exposed amount of the outer wall surface of the second case portion. It will be possible to recognize well what state is.

[0161] In addition, a sensor that outputs a detection signal corresponding to the amount of the cover tape stored in the tape storage box and a notification unit that performs notification according to the detection signal from the sensor are provided. Can do.

[0162] In this way, since notification is made according to the amount of cover tape accommodated, an operator involved in the component supply device can manage the tape storage box easily and appropriately based on the notification. become.

[0163] Furthermore, a sensor that outputs a detection signal corresponding to an increase in the amount of the cover tape stored in the tape storage box, an actuator that displaces the second case, and a detection signal from the sensor The force control means controls the actuator so as to displace the second case in the direction of increasing the accommodation volume.

In this way, the second case portion is automatically displaced according to an increase in the amount of cover tape accommodated, and the capacity of the tape storage box increases. Therefore, it is possible to suppress the burden on the worker and the like related to the component supply apparatus, and to increase the accommodation volume more efficiently, the force S can be used.

 [0165] Further, the tape storage box can be detachably attached to a frame holding the delivery means and the peeling means.

[0166] In this way, when a failure occurs in either the tape storage box or the parts on the frame side, only one of the troubles can be repaired, replaced, or the like.

The structure is excellent in maintainability and economy.

[0167] Further, in the case where an electrical component capable of supplying power or outputting a signal is provided to the sending means and the peeling means, a frame for holding the sending means and the peeling means is provided. It can be set as the structure by which the said electrical equipment part is attached so that attachment or detachment is possible.

[0168] In this way, if any one of the parts on the frame side or the electrical component has a defect, only one of the defect can be repaired, replaced, etc. It becomes the structure excellent in economical efficiency.

[0169] Further, the tape storage box can be detachably attached to the frame and the electrical component.

[0170] This makes it possible to repair, replace, etc. the frame-side parts, electrical parts, and tape storage box independently of each other, which is further advantageous in terms of cost and maintenance.

[0171] Further, the frame can be made of a metal material, and the tape storage box can be made of a resin material.

[0172] By doing this, it is possible to ensure the rigidity of the frame and reduce the weight of the tape storage box.

[0173] Also, at least a part of the tape storage box is made of a resin material having transparency, and the inside of the tape storage box can be visually recognized through the resin material having transparency. Monkey.

 [0174] This makes it possible for the operator to visually recognize the cover tape stored in the tape storage box, and makes it easier to properly grasp the tape collection time and the like.
