<Description of Embodiments of the Present Disclosure>
(1) The component supply device includes a delivery device that delivers the component supply tape to a component supply position, a take-up device that takes back the cover tape from the component supply tape delivered by the delivery device, and a take-up device that takes back the cover tape from the component supply tape. A storage unit that stores the cover tape, and a detection unit that is positioned in the storage unit and detects the storage state of the cover tape.

With the above configuration, since it is possible to detect the storage state of the cover tape, it is unnecessary for the operator to check the storage state, and the labor required for checking the storage state can be reduced.

(2) The detection unit may detect whether or not the cover tape is stored in the storage unit in an overcrowded state. With this configuration, excessive accumulation of cover tape relative to the storage can be detected.

(3) The detection unit may be arranged near an entrance of the storage unit. With this configuration, it is possible to detect excessive accumulation of the cover tape near the entrance, and to suppress the cover tape from being caught in the take-up device near the entrance.

(4) The detection unit includes a pressed portion having a convex portion protruding toward the inside of the storage portion, a biasing portion that biases the convex portion toward the inside of the storage portion, and the pressed portion. and a photosensor that detects displacement of the part.

When the cover tape in the storage portion presses the pressed portion, the pressed portion is displaced, and the displacement sensor detects the displacement of the pressed portion. Accordingly, the storage state of the cover tape in the vicinity of the pressed portion can be detected based on the presence of the cover tape pressing the pressed portion.

(5) The detection section may be a limit switch that detects the storage state of the cover tape. Limit switches are smaller than photosensors and have less space constraints. This improves the degree of freedom of positioning when installing the detector.

(6) The component mounting apparatus may include a component supply device, a main control section, a reporting section for reporting warning information, and a warning stop section for stopping reporting of the warning information. When the detection unit detects an overcrowded state, the main control unit causes the notification unit to notify the warning information. If the notification of information is not stopped, the operation of the component supply device is stopped.

In the above configuration, if the cause of the warning information is removed before the predetermined time elapses after the notification of the warning information, and if the warning stop section stops the notification of the warning, The component mounting process by the component mounting apparatus can be continued. Further, the main control unit stops the component supply device when a predetermined time has elapsed after the notification of the warning information. Therefore, the cover tape is not excessively stored in the storage portion, and the component supply device can be safely stopped before the cover tape is caught in the retraction portion.

After the component supply device is stopped, it can be restarted simply by ejecting the cover tape in the storage section, and the stop time of the component supply device can be shortened.

<Embodiment 1>
One embodiment of the present invention is described below.

1. Overall Configuration of Component Mounting Apparatus As shown in FIG. A driving device 20 for moving and a component supply device 50 are provided. In the following description, the longitudinal direction of the base 11 (horizontal direction in FIG. 1) is the X direction, the depth direction of the base 11 (vertical direction in FIG. 1) is the Y direction, and the vertical direction in FIG. 2 is the Z direction. do.

The transport conveyor 14 is arranged in the center of the base 11 . The transport conveyor 14 has a pair of transport belts 15 circulating in the X direction, and transports the printed circuit board P on the transport belts 15 in the X direction by friction with the belts. In Embodiment 1, the printed circuit board P is carried into the component mounting apparatus 10 from the left side shown in FIG. The conveyer 14 conveys the printed circuit board P to a working position in the center of the base 11 and stops there.

Four component supply units 12 are provided on the base 11 so as to surround the working position. A large number of component supply devices 50 for supplying components W are installed adjacent to each component supply unit 12 in the X direction. A component supply device 50 according to the first embodiment is a feeder.

At the working position, the component W is supplied by the component supply device 50 and the component W is mounted on the printed circuit board P by the mounting head 31 of the head unit 30 . After that, the printed circuit board P on which the component W is mounted is transported rightward in FIG.

The driving device 20 is roughly composed of a pair of support legs 21 , a head support 25 , a Y-axis ball screw 23 , a Y-axis motor 24 , an X-axis ball screw 27 and an X-axis motor 28 . A pair of support legs 21 are installed on the base 11 . Both support legs 21 are located on both sides of the working position and extend straight in the Y direction. A guide rail 22 extending in the Y direction is installed on the upper surfaces of both support legs 21 . A head support 25 is attached to the left and right guide rails 22 while engaging both ends in the longitudinal direction.

A Y-axis ball screw 23 extending in the Y direction is attached to the right support leg 21 . A ball nut (not shown) is screwed onto the Y-axis ball screw 23 . A Y-axis motor 24 is attached to the Y-axis ball screw 23 . When the Y-axis motor 24 is energized, the ball nut advances and retreats along the Y-axis ball screw 23 . direction (Y-axis servomechanism).

The head support 25 has a shape elongated in the X direction. As shown in FIG. 2, the head support 25 is provided with a guide member 26 extending in the X direction. A head unit 30 is attached to the guide member 26 so as to be movable along the axis of the guide member 26 . An X-axis ball screw 27 extending in the X direction is attached to the head support 25 . A ball nut (not shown) is screwed onto the X-axis ball screw 27 . An X-axis motor 28 is attached to the X-axis ball screw 27 . When the X-axis motor 28 is energized, the ball nut advances and retreats along the X-axis ball screw 27. As a result, the head unit 30 fixed to the ball nut moves in the X direction along the guide member 26 (X-axis servo mechanism). ).

Therefore, by controlling the X-axis motor 28 and the Y-axis motor 24 in combination, the head unit 30 can be moved on the base 11 within the XY plane.

In the head unit 30, a plurality of mounting heads 31 for mounting the components W are mounted in rows. Each mounting head 31 is configured such that it can rotate about its axis by being driven by an R-axis motor (not shown) and can be moved up and down with respect to the head unit 30 by being driven by a Z-axis motor (not shown). Negative pressure is supplied to each mounting head 31 from negative pressure means (not shown), and the mounting head 31 is configured to be able to pick up the component W by this negative pressure.

With such a configuration, by operating the X-axis motor 28, the Y-axis motor 24, and the Z-axis motor at predetermined timings, the component W supplied from the component supply device 50 is sucked by the mounting head 31. , the process of mounting on the printed circuit board P can be executed.

As shown in FIG. 1, a component recognition camera 13 is arranged on a base 11 with its imaging surface facing upward. The component recognition camera 13 captures an image (lower surface image) of the component W picked up by the mounting head 31 and detects the pickup posture of the component W by the mounting head 31 .

As shown in FIG. 2, a board recognition camera 32 is arranged in the head unit 30 with its imaging surface facing downward. Since the board recognition camera 32 is integrated with the head unit 30, an image of any position on the printed board P can be picked up by driving the X-axis servo mechanism and the Y-axis servo mechanism.

2. Configuration of Component Supply Tape and Component Supply Apparatus As shown in FIG. 3, the component supply tape 40 is composed of a carrier tape 41 and a cover tape 45 attached thereto. The material of the carrier tape 41 and the cover tape 45 is synthetic resin, for example. The carrier tape 41 has upwardly open hollow component storage portions 42 at regular intervals, and each component storage portion 42 stores a component W such as a chip resistor. Engagement holes 43 are provided at regular intervals along one edge of the carrier tape 41 . The component supply tape 40 is wound around and supported by a reel (not shown) at a rear position of the component supply device 50 .

As shown in FIG. 4, the component supply device 50 includes a delivery device 54, a tape guide 58, a take-up device 61, a storage section 68, and a frame 51 to which these are attached. Hereinafter, in the description of the component supply device 50, the X direction is the width direction, and the Y direction is the front-rear direction.

The frame 51 has a shape elongated in the front-rear direction, and is made of die-cast aluminum, for example. The frame 51 is provided with a tape passage 52 through which the component supply tape 40 passes. The tape passage 52 extends forward from the lower rear end of the frame 51 . After that, the tape path 52 extends obliquely upward and continues to the upper surface of the frame 51 .

The delivery device 54 is provided on the front side of the frame 51 . The delivery device 54 comprises a first motor 55 , a gear train 56 comprising a plurality of gears, and a sprocket 57 . The gear train 56 transmits the power of the first motor 55 to rotate the sprocket 57 . The sprocket 57 is integrally provided on the left side of the gear at the top of the front end of the gear train 56 (backward in the drawing of FIG. 4), and has the same rotating shaft as the gear at the top of the front end. Teeth 57A are formed on the outer periphery of the sprocket 57 at regular intervals. The teeth 57A of the sprocket 57 are engaged with the hole walls of the engagement holes 43 of the component supply tape 40, and by rotating the sprocket 57, the component supply tape 40 is moved to the component supply position G in the front part of the component supply device 50. can be sent to

The tape guide 58 has a shape elongated in the front-rear direction and is installed on the front portion of the upper surface of the frame 51 . As shown in FIG. 5, the tape guide 58 has guide walls 58A that guide both sides of the component supply tape 40 so that the delivered component supply tape 40 does not tilt. A slit-shaped cover tape peeling portion 60 is provided on the ceiling wall 59 of the tape guide 58 . The cover tape peeling section 60 peels the cover tape 45 from the component supply tape 40 upstream of the component supply position G (on the left side in FIG. 5), and the peeled cover tape 45 is folded back upstream (rearward). As will be described later, the peeled cover tape 45 is drawn backward by the drawing portion 64 .

After peeling off the cover tape 45 , the carrier tape 41 supplies the component W to the component supply position G in front of the cover tape peeling section 60 . The mounting head 31 moves to the component supply position G at the timing when the component W is sent to the component supply position G, and picks up the component W from the component storage section 42 of the carrier tape 41 .

As shown in FIG. 4 , the take-up device 61 includes a second motor 62 , a gear train 63 made up of a plurality of gears, and a pull-in portion 64 . The pull-in portion 64 is composed of a pull roller 65 and pinch rollers 66 . The gear train 63 transmits the power of the second motor 62 to rotate the pulling roller 65 . The tension roller 65 and the pinch roller 66 are arranged to face each other at an introduction port (an example of an “entrance”) 68A of the storage section 68 . The pull roller 65 and the pinch roller 66 are gears provided so as to mesh with each other.

The pinch roller 66 is fixed to a lever 67 that can swing around a hinge 67A. By operating the lever 67, the pinch roller 66 is displaced between a state in which it contacts the tension roller 65 and a state away from it. It is possible. A spring 67B is attached to the lever 67 to urge the pinch roller 66 downward. Therefore, as shown in FIG. 6, the pinch rollers 66 are held in mesh with the tension rollers 65 while sandwiching the cover tape 45 therebetween.

Therefore, when the pulling roller 65 is rotated, the cover tape 45 is pulled backward by the rotating pulling roller 65 and pinch roller 66 and stored in the storage portion 68 . As shown in FIG. 6, a concave tape groove 53 is formed in the upper wall surface of the frame 51 on the front side of the pulling roller 65 . The cover tape 45 is slidably contacted with the inner wall of the tape groove 53 so as to be positionally regulated so as not to shift laterally with respect to the tension roller 65 and the pinch roller 66 .

As shown in FIG. 4, the housing portion 68 is provided at the rear portion of the frame 51, and an introduction port 68A for introducing the cover tape 45 is formed at the upper front end thereof. The introduction port 68A is provided with the tension roller 65 and the pinch roller 66 described above. The cover tape 45 separated from the carrier tape 41 is stored in the storage portion 68 through the introduction port 68A.

A discharge port 68</b>F is formed at the rear end of the storage portion 68 . A cover member 69 that can be opened and closed around a hinge 69A is attached to the outlet 68F. The lid member 69 maintains the closed state by being attracted to the storage section 68 by a magnet (not shown). A handle is attached to the lid member 69 so that the operator can open and close the lid member 69 as necessary, such as when ejecting the cover tape 45 in the storage section 68 .

The upper surface wall 68B and the lower surface wall 68C are the ceiling surface and the bottom surface of the storage section 68, respectively. The bottom wall 68C has an inclined portion 68D that descends rearward. The inclination angle of the inclined portion 68D with respect to the horizontal plane increases as it approaches the introduction port 68A, making it easier for the cover tape 45 in the vicinity of the introduction port 68A to move rearward along the lower surface wall 68C. An opening 68E is formed in the bottom wall 68C. Below the bottom wall 68C, a detector 70, which will be described later, is arranged.

FIG. 7 is a block diagram of the component supply device 50 and the component mounting device 10. As shown in FIG. In FIG. 7, portions unrelated to the storage and ejection of the cover tape 45 are omitted. The component supply device 50 includes a control section 81 . The control unit 81 is a controller that controls the component supply device 50 . The control unit 81 is connected to the detection unit 70 to be described later, receives detection results and transmits them to the main control unit 16, and turns on the first motor 55 and the second motor 62 according to commands from the main control unit 16. /OFF control, etc.

The component mounting apparatus 10 includes a main control section 16, a warning light (an example of a "notification section") 17, and a warning stop switch (an example of a "warning stop section") 18 (see FIG. 7). The main control unit 16 is a controller that controls the entire component mounting apparatus 10 including the component supply device 50, and controls the drive device 20, the head unit 30, the component supply device 50, the warning light 17, and the like. Further, the main control section 16 receives the detection result of the detection section 70 described later via the control section 81 of the component supply device 50 . Based on the detection result, it is determined whether to turn on the warning light 17 and whether to stop the component mounting apparatus 10 .

The warning light 17 is a so-called revolving light. Instead of the warning light 17, a device that emits a sound such as a buzzer or an image display device such as a display may be used. Also, these may be used in combination.

The warning stop switch 18 is a switch that transmits a signal to stop the notification of the warning information to the main control unit 16 when the operator eliminates the cause of the warning after the notification of the warning information by the warning light 17 . The warning stop switch 18 may be a display on a touch panel of the component mounting apparatus 10, for example.

3. Storage Operation of Cover Tape The storage operation of the cover tape 45 in the storage portion 68 will be described with reference to FIGS. 8 and 9. FIG. FIG. 8 shows the storage state of the cover tape 45 immediately after the start of component supply. Immediately after the start of component supply, the storage amount of the cover tape 45 in the storage section 68 is small, and the area from the introduction port 68A at the front to the discharge port 68F at the rear is generally sparse.

As the storage amount of the cover tape 45 in the storage portion 68 increases, as shown in FIGS. When the entire 68 is in a tight state (full state), the lid member 69 is pushed by the cover tape 45 to open, and the operator discharges/removes the cover tape 45 in the storage section 68 .

4. Cover tape storage failure and its detection Due to aging deterioration of the storage portion 68 and the influence of the material of the cover tape 45, friction may increase and the flow of the cover tape 45 in the storage portion 68 may become poor. If the flow of the cover tape 45 becomes poor, as shown in FIGS. 10 and 11, the cover tape 45 accumulates at the inlet portion of the storage section 68, resulting in an "overcrowded state" (occurrence of poor storage). The "overcrowded state" is a state in which the storage density of the cover tapes 45 is higher than in the dense state, and the cover tapes 45 are excessively accumulated in the storage section 68 due to poor storage or ejection failure.

In this embodiment, the detection unit 70 provided in the storage unit 68 detects the “congested state (improper storage)” of the cover tape 45 .

As shown in FIG. 12, the detection section 70 is arranged at the entrance portion of the storage section 68 (in the vicinity of the introduction port 68A and the retraction section 64) and below the lower surface wall 68C. The detection unit 70 includes a pressed portion 71 , a coil spring (an example of a “biasing portion”) 72 , and a photosensor (an example of a “displacement sensor”) 73 .

The photosensor 73 is of a transmissive type in which a light-emitting element and a light-receiving element are arranged on both sides of the slit 73A so as to face each other with a predetermined gap therebetween. Displacement of an object is detected by utilizing the fact that the output of the light receiving element changes depending on whether the light emitted by the light emitting element is incident on the light receiving element or not.

When a light shielding object (light shielding portion 71C, which will be described later) blocks the optical path 73B, the light entering the light receiving element is interrupted and the output of the light receiving element changes. Therefore, the displacement of the light blocking object can be detected from the output change of the light receiving element. Since the photosensor 73 does not have a mechanical contact, it is a highly durable sensor that does not cause deterioration of the sensor sensitivity or erroneous detection due to deterioration of the contact.

The pressed portion 71 has a dog 71A (an example of a “projection”), a support portion 71B, and a light blocking portion 71C. The dog 71A has a triangular prism shape whose axis is the width direction. The length of the dog 71A in the width direction is slightly smaller than the width of the internal space of the storage portion 68. As shown in FIG. The clearance between the dog 71A and the side wall is small, and the cover tape 45 is difficult to enter into the clearance. Further, the dog 71A and the side wall of the storage portion 68 are not in contact with each other, and the dog 71A can be displaced in directions other than the width direction inside the storage portion 68 .

The support portion 71B is a plate-shaped member that extends in the front-rear direction while being inclined, and is connected to the dog 71A at the rear end and to the hinge 75 at the front end. The hinge 75 is a hinge whose axis is the width direction. The pressed portion 71 is rotatable around the axis of the hinge 75 .

The light shielding portion 71C is a bar-shaped or plate-shaped member extending substantially downward from the lower surface of the support portion 71B. The upper end of the light shielding portion 71C is connected to the support portion 71B, and the lower end thereof is inserted into the slit 73A. The light shielding portion 71C is made of a light shielding material (opaque resin, metal, or the like).

The coil spring 72 is a compression coil spring and has its lower end fixed to the fixing portion 76 . The upper end of the coil spring 72 is in contact with the lower surface of the dog 71A and biases the dog 71A upward. 8 and 12 show a state in which the coil spring 72 urges the dog 71A upward and the upper surface of the support portion 71B is in contact with the edge of the opening 68E. In this state, the pressed portion 71 is pressed against the edge of the opening 68E and cannot be displaced (rotated) upward any more. The position of the pressed portion 71 at this time is set as a reference position.

When the pressed portion 71 is at the reference position, the dog 71A passes through the opening 68E from the outer side (lower side) of the storage section 68 toward the inner side (upper side). At this time, the upper end of the dog 71A protrudes inward from the lower surface wall 68C.

As shown in FIGS. 10 and 11, when the cover tape 45 is in an "overcrowded state" at the entrance portion (in the vicinity of the introduction port 68A and the retraction portion 64) of the storage portion 68, the force of the cover tape 45 pushing the dog 71A increases. , exceeds the force of the coil spring 72 .

As a result, the dog 71A is displaced from the reference position in a direction to reduce the amount of protrusion of the dog 71A against the coil spring 72, and the light blocking portion 71C blocks the light path 73B of the photosensor 73. The light blocking of the optical path 73B changes the output of the light-receiving element, and as a result, it is possible to detect the overcrowded state (insufficient storage) of the cover tape 45. FIG.

4. Detecting process for defective storage of cover tape The detection process for detecting defective storage of the cover tape 45 is composed of five steps S10 to S50 (see FIG. 13).

With the start of production of the printed circuit board P by the component mounting apparatus 10, when the supply of the components W by the component supply apparatus 50 is started, the take-up apparatus 61 draws the cover tape 45 into the storage section 68, and stores the cover tape 45 in the storage section 68. The amount increases (S10).

After starting the supply of the parts W, the control unit 81 determines whether or not the detection unit 70 has detected the "overcrowded state" of the cover tape 45 (S20). When the cover tape 45 is smoothly stored in the storage portion 68, the cover tape 45 does not become "overcrowded" at the entrance portion of the storage portion 68, and a NO determination is made in S20. As a result, the loop of R1 is repeated.

On the other hand, when the friction increases due to aged deterioration of the storage portion 68 and the influence of the material of the cover tape 45, the flow of the cover tape 45 in the storage portion 68 deteriorates, and the cover tape 45 accumulates at the entrance portion of the storage portion 68. and become “overcrowded”.

Then, the detection unit 70 detects the "overcrowded state" of the cover tape 45, and the detection result is transmitted to the main control unit 16 via the control unit 81 (S20: YES).

When receiving the detection result of the detection unit 70, the main control unit 16 turns on the warning light 17 to notify the operator of warning information (S30). Even after the warning light 17 is turned on, the production of the printed circuit board P and the supply of the parts W continue, and the amount of the cover tape 45 stored in the storage portion 68 increases.

After that, the process proceeds to S40, and the main control unit 16 determines whether the following two restoration measures have been executed before a predetermined time has elapsed since the warning light 17 was turned on.

- Ejecting the cover tape 45 accumulated at the entrance of the storage section 68 - Pressing the warning stop switch 18

If these restoration measures are executed within the predetermined time, the production of the printed circuit board P and the supply of the parts W are continued (S40: YES). On the other hand, if it is not executed within the predetermined time, production of the printed circuit board P is stopped (S50).

5. Description of Effect With the above configuration, the storage state of the cover tape 45 in the storage section 68 can be detected. Specifically, the “congestion state” of the cover tape 45 at the entrance portion of the storage portion 68 can be detected.

By detecting the "overcrowded state" of the cover tape 45 at the entrance of the storage section 68, the cover tape 45 excessively accumulated at the entrance of the storage section 68 is prevented from being caught in the pull roller 65 or the pinch roller 66. can.

<Embodiment 2>
Embodiment 2 will be described with reference to FIGS. 14 and 15. FIG. The component supply device 150 according to the second embodiment differs from the detection section 70 of the first embodiment in the configuration of the detection section 170 . The rest of the configuration of the component supply device 150 and the configuration of the surface mounter are the same as those of the first embodiment, so descriptions thereof will be omitted.

As shown in FIG. 14, the detector 170 has a limit switch 171 . The limit switch 171 has a lever 172 , a hinge 173 , a housing 174 and a pin 175 .

The lever 172 is a plate-shaped member extending in the front-rear direction. A curved portion 172</b>A is formed at the rear end of the lever 172 so as to be convex toward the inside of the storage portion 68 . A front end of lever 172 is connected to housing 174 via hinge 173 . The hinge 173 is a hinge whose axis is in the width direction, and the lever 172 is rotatable around the axis of the hinge 173 .

The pin 175 protrudes upward from the upper surface of the housing 174 and its upper end is in contact with the lower surface of the lever 172 . When a pressing force is applied to the lever 172, the lever 172 rotates and pushes down the pin 175 (see FIG. 15). At this time, a contact (not shown) switches inside the housing 174 to change the output of the limit switch 171 .

The pin 175 is biased upward by an elastic body (for example, a compression coil spring) built in the housing 174 . Therefore, the pin 175 is pressed when the lever 172 is pressed with a pressing force equal to or greater than a predetermined value.

FIG. 14 shows a case where the cover tape 45 in the storage portion 68 is in contact with the lever 172, but the cover tape 45 is loosely stored, the pressing force is small, and the pin 175 is not pressed. there is At this time, the output of the limit switch 171 does not change.

As shown in FIG. 15, when the cover tape 45 accumulates at the entrance of the storage section 68 and becomes "congested", the lever 172 rotates and pushes the pin 175 down. Then, the output of the limit switch 171 changes, and the detecting section 170 detects the "overcrowded state" of the cover tape 45 .

<Other embodiments>
The present invention is not limited to the embodiments explained by the above description and drawings, and the following embodiments are also included in the technical scope of the present invention.

(1) In the above-described embodiment, the detection unit 70 is used to detect the “congested state” of the cover tapes 45 at the entrance of the storage unit 68 . Alternatively, the full state of the cover tape 45 may be detected. In this case, the detection unit 70 is preferably arranged on the discharge port 68</b>F side of the storage unit 68 . Further, the sensitivity adjustment of the detection unit 70 (sensitivity for full detection) can be performed, for example, by changing the coil spring 72 to a spring with a different spring constant.
