However, in component mounting machines, multiple feeders of the same shape are arranged close together in parallel to each other, so there are cases where the carrier tape is inserted into a feeder other than the feeder instructed to supply components, i.e., the carrier tape is mistakenly supplied to a feeder that is not the intended supply target.

As a result, carrier tapes containing different types of components are mixed in the feeder to be replenished, and if it takes time to notice this mistake, in the worst case scenario, it could result in incorrect mounting of the wrong components onto the board.

The present invention was made in consideration of the above-mentioned problems, and aims to provide a feeder that detects whether a carrier tape has been correctly inserted into a feeder that requires parts to be replenished.

The present specification includes a flat housing, a tape insertion opening provided at the rear of the housing into which a first carrier tape and a second carrier tape following the first carrier tape are inserted, and the first carrier tape. The first carrier tape is conveyed by engaging with the engagement hole of the carrier tape, and after the conveyance, the second carrier tape is conveyed along the conveyance path by engaging with the engagement hole of the second carrier tape. a sprocket, a tape insertion detection sensor that detects a first carrier tape that is transported along the transport path and a second carrier tape that is transported after the first carrier tape is transported; and an indicator lamp that indicates that the second carrier tape has been correctly inserted into the tape insertion slot when the insertion of the second carrier tape is detected, and the indicator lamp of the feeder that has been instructed to supply parts The display will be different depending on whether the tape is correctly inserted into the tape insertion slot of the feeder that is instructed to replenish parts or if it is inserted into the tape insertion slot of a feeder that is different from the feeder where component replenishment is instructed. , disclose the feeder.

The disclosed feeder can accurately notify the operator by displaying an indicator lamp that the correct carrier tape has been inserted into the feeder that has been instructed to replenish parts.

Both sides of the cover tape 902 are adhered to both sides of the top surface of the base tape 901 with an adhesive 902a (see FIG. 2), and usually closes the top of the storage section 901a to prevent parts from flying out. Note that the cover tape 902 is made of a transparent polymer film.

As shown in FIG. 3, a bottom tape 903 is adhered to the lower surface of the base tape 901. This bottom tape 903 prevents the components stored in the storage section 901a from falling off. The bottom tape 903 is made of paper material, polymer film, or the like, and is transparent or semitransparent.

A carrier tape 900 wound around a first reel 810 and a second reel 820 can be inserted into each feeder 21 . Then, the carrier tape 900 wound around one reel 810 (820) is sequentially conveyed by the feeder 21 to a component extraction position 21a provided at the tip of the feeder 21. Thereby, the component held by the carrier tape 900 is positioned at the component removal position 21a. Further, the carrier tape 900 wound around the other reel 820 (810) is not fed by the feeder 21 and is on standby.

In the following, for convenience of explanation, in order to distinguish between the carrier tape 900 being transported (in use) and the carrier tape 900 on standby, the former will be referred to as the first carrier tape 900A and the latter as the second carrier tape 900B. It is sometimes called. In this case, after all the parts stored in the first carrier tape are used, the second carrier tape becomes the first carrier tape, so the first carrier tape and the second carrier tape are It's not something I'm referring to.

The downstream pressing member 33 is attached to a first support member 30-1 and a second support member 30-2 attached to the feeder main body 21b so as to be movable in the vertical direction via a shaft 34-1. A coil spring 35-1 that urges the downstream pressing member 33 downward is attached to the shaft 34-1. A holding portion 33d that contacts the rail 38 on the third sprocket 63 is formed in front of the downstream holding member 33. With such a configuration, the holding portion 33d moves toward and away from the rail 38. As shown in FIG. 5, an intrusion portion 33b is cut out at the lower rear end of the holding portion 33d.

The upstream pressing member 32 has a block shape and is provided along the rear upper surface of the rail 38. The upstream pressing member 32 is attached downwardly from the rear of the downstream pressing member 33 via a shaft 34-2 so as to be movable in the vertical direction. The upstream pressing member 32 is adjacent to the rear of the pressing portion 33d. A coil spring 35-2 that biases the upstream pressing member 32 downward is attached to the shaft 34-2. With this configuration, the upstream pressing member 32 moves toward and away from the rail 38. A tape insertion opening 32a is formed at the lower part of the rear end of the upstream pressing member 32.

As shown in FIG. 5, the stopper member 31 has a block shape and is provided adjacent to the upstream pressing member 32 on the downstream side. The stopper member 31 is pivotally supported by the downstream pressing member 33 at a shaft support 31b formed at its intermediate portion, so that the stopper member 31 can swing. A lower portion of the stopper member 31 in front of the shaft support 31b is formed with a contact portion 31a that projects downward.

A guide portion 28b bent upward is formed at the rear end of the floating prevention member 28. The torsion spring 29 is attached to the feeder body 21b above the floating prevention member 28, and biases the floating prevention member 28 downward. The torsion spring 29 brings the lower surface of the floating prevention member 28 into close contact with the upper surface of the rail 38.

In addition, a space 38c is formed on the rail 38 between the second sprocket 62 and the third sprocket 63.

The control unit 39 controls the feeder 21 and controls the rotation of the first motor 22 and the second motor 23. The control unit 39 includes a microprocessor and a driver that supplies drive current to the motors 22 and 23.

The feeder main body 21b on the downstream side of the third sprocket 63 is provided with a first sensor 65 that detects the presence or absence of the carrier tape 900 and outputs the detection signal to the control section 39. The first sensor 65 is a sensor that detects the boundary between the first carrier tape 900A and the second carrier tape 900B. A second sensor 66 is provided on the feeder main body 21 b on the upstream side of the second sprocket 62 to detect the presence or absence of the carrier tape 900 and output a detection signal thereof to the control section 39 .

As shown in FIG. 8, display lamps 85 serving as notification means are provided at rear portions of the plurality of feeders 21 at positions easily visible to the operator. The display lamp 85 is turned on when the carrier tape 900 is inserted into a feeder 21 different from the feeder 21 to which parts supply is instructed by the parts supply instruction section 200a of the control device 200, and notifies the operator. In addition, in FIG. 8, the tape peeling device 70 provided on the upper part of the feeder main body 21b is omitted.

Further, at the rear of the plurality of feeders 21, as shown in FIG. An insertion detection sensor 90 is disposed closer to the tape insertion opening 32a than the fourth sprocket 64.

When the feeder 21 is installed in the slot 20a of the component supply unit 20, power is supplied from the main body of the component mounter 100 to the feeder 21 via the communication connector 80 (see FIG. 7), and the feeder ID, etc. Necessary information is transmitted from the feeder 21 side to the control device 200 of the component mounter 100. Thereby, information on the parts fed by the carrier tape 900 loaded in the feeder 21 is acquired based on the serial ID of the feeder 21 and stored in the control device 200.

Next, the operation of the feeder 21 will be described. The operator inserts the carrier tape 900 into the tape insertion opening 32a shown in FIG. 4. Then, the fourth engagement protrusion 64a engages with the engagement hole 901b formed at the tip of the inserted carrier tape 900, and the carrier tape 900 is transported to the third sprocket 63 by the fourth sprocket 64. Since the fourth engagement protrusion 64a is formed only on a part of the outer periphery of the fourth sprocket 64, when the fourth engagement protrusion 64a engages with the engagement hole 901b of the carrier tape 900, the carrier tape 900 moves intermittently toward the third sprocket 63. Therefore, the carrier tape 900 is not suddenly drawn toward the third sprocket 63.

The leading end of the carrier tape 900 conveyed by the fourth sprocket 64 enters below the holding part 33d from the entry part 33b. Then, when the engagement hole 901b formed in the carrier tape 900 engages with the third engagement protrusion 63a, the carrier tape 900 is conveyed to the second sprocket 62 side by the third sprocket 63. Since the third engaging protrusion 63a is formed on the outer circumference of the third sprocket 63 over the entire circumference, the carrier tape 900 is conveyed to the second sprocket 62 side in a short time. Note that the carrier tape 900 is pressed from above by the holding portion 33d so that the engagement hole 901b and the third engagement protrusion 36a do not come out of engagement.

Further, the leading end of the carrier tape 900 enters below the floating prevention member 28 from between the guide portion 28b and the rail 38. The leading end of the carrier tape 900 is prevented from floating off the rail 38 by the floating prevention member 28 and is transported toward the second sprocket 62 .

When the second sensor 66 detects the leading end of the carrier tape 900 transported by the third sprocket 63, the first motor 22 and the second motor 23 rotate the sprockets 61 to 64 intermittently at the component pitch interval. When the engagement hole 901b formed in the carrier tape 900 engages with the second engagement protrusion 62a, the second sprocket 62 sends the carrier tape 900 to the tape peeling device 70, which peels off the cover tape 902 from the carrier tape 900. Then, when the engagement hole 901b formed in the carrier tape 900 engages with the first engagement protrusion 61a, the first sprocket 61 positions the components stored in the carrier tape 900 in sequence at the component removal position 21a.

When the first carrier tape 900A is being transported by the feeder 21, as shown in FIG. 5, the first carrier tape 900A presses against the contact portion 31a, and the stopper member 31 is swung in a direction such that the stop portion 31c approaches the rail 38 against the biasing force of the spring 36, and the rear lower end of the stopper member 31 comes into contact with the upper surface of the first carrier tape 900A.

Therefore, in this state, when the worker inserts the second carrier tape 900B from the tape insertion opening 32a between the upstream pressing member 32 and the first carrier tape 900A, the leading end of the second carrier tape 900B comes into contact with the stop portion 31c of the stopper member 31, as shown in FIG. 5. This prevents the second carrier tape 900B from being transported downstream, and the second carrier tape 900B waits in that position.

Note that, at this time, the first carrier tape 900A is wound around the reel 810 on the front side, and the second carrier tape 900B is wound around the reel 820 on the rear side.

When the rear end of the first carrier tape 900A is conveyed downstream from the leading end of the second carrier tape 900B, as shown in FIG. It engages with the mating protrusion 64a. Further, when the rear end of the first carrier tape 900A passes the stopper member 31, the stopper member 31 is swung by the biasing force of the spring 36, and the blocking of the second carrier tape 900B from being conveyed is released.

As a result, the second carrier tape 900B enters below the holding portion 33d from the entry portion 33b by the fourth sprocket 64. Then, the engagement hole 901b formed in the second carrier tape 900B is engaged with the third engagement protrusion 63a, and the second carrier tape 900B is conveyed toward the second sprocket 62 by the third sprocket 63.

Note that when the tip of the second carrier tape 900B pushes up the contact portion 31a, the stopper member 31 is swung again against the biasing force of the spring 36, as described above, and the stopper member 31 pushes up the new carrier tape 900. prevent the intrusion of

When all the components are removed from the first carrier tape 900A, the used reel 810 is removed from the reel holding section 50.

Note that when inserting a new carrier tape 900 into the feeder 21, the reel 810 wound with the currently used carrier tape 900 (first carrier tape 900A) and the newly inserted carrier tape 900 (second carrier tape 900A) are used. A barcode reader reads the barcodes affixed to each reel 810 wound with tape 900B), transmits the serial ID of the component stored in each reel to the control device 200 of the component mounter 100, and confirms the correct serial ID. A so-called verification process is performed to check whether the carrier tape contains components.

Next, the incorrect tape insertion detection operation, which detects that the carrier tape 900 has been inserted into the wrong feeder 21 for which parts supply has been instructed, will be described based on the flowchart in Figure 9, which is executed by the control device 200.

When the parts replenishment instruction unit 200a of the control device 200 instructs the feeder 21 of slot number "NX" to replenish parts (step S1), the operator inserts the carrier tape containing the parts for which replenishment has been instructed. While holding the reel 820 wound with 900 on the reel holding part 50, the tip of a new carrier tape 900 (second carrier tape 900B) is placed on top of the first carrier tape 900A that has already been inserted into the feeder 21. Insert the tape from the tape insertion slot 32a (step S2). When the second carrier tape 900B is inserted, the tape insertion detection sensor 90 is turned on, and it is detected that the carrier tape 900 is inserted into the tape insertion opening 32a.

The operation signal of the tape insertion detection sensor 90 is transmitted to the control device 200. Then, in the control device 200, it is determined whether the turned ON tape insertion detection sensor 90 belongs to the feeder 21 of the slot No. "NX" for which the component supply instruction section 200a has instructed the component supply instruction section 200a. (Step S3). If it is determined that the feeder 21 to which component replenishment was instructed and the feeder 21 to which the tape insertion detection sensor 90 was turned ON are different (if the determination result is NO), the slot No. "NX" is selected. The indicator lamp 85 of the feeder 21 is turned on to notify the operator that the carrier tape 900 has been inserted into the wrong feeder 21 (step S4).

When the indicator lamp 85 is lit, the operator pulls out the carrier tape 900 from the feeder 21 into which the carrier tape 900 was inserted by mistake, and reinserts it into the feeder 21 of slot number "NX".

In addition, if it is determined that the feeder 21 to which parts replenishment has been instructed and the feeder 21 to which the tape insertion detection sensor 90 has been turned on are the same (if the determination result is YES), the indicator lamp 85 will be turned on. The light is not turned on, and the operator is notified that the carrier tape 900 has been correctly inserted into the feeder 21 (step S5). In this case, the operation of component mounter 100 continues.

Note that the indicator lamp 85 provided in each feeder 21 may be arranged so that when the carrier tape 900 is inserted correctly, the indicator lamp 85 lights up, and when the carrier tape 900 is inserted incorrectly, the indicator lamp 85 blinks. good. Alternatively, it can be configured with two LEDs (for example, blue and red), in which case the blue LED lights up when the carrier tape 900 is inserted correctly, and the blue LED lights up when the carrier tape 900 is inserted incorrectly. In this case, a red LED may be turned on.

According to the embodiment described above, when the carrier tape 900 is inserted into a feeder 21 different from the feeder 21 to which component replenishment is instructed, the indicator lamp 85 indicates to the operator that the carrier tape 900 is in the wrong feeder. 21, the operator who replenishes the parts can quickly take necessary measures.

As a result, it is possible to take measures such as resupplying parts at a stage when there is a surplus in the number of parts currently in use, and the impact on production can be minimized.

Furthermore, according to the embodiment described above, the indicator lamp 85 is provided on each of the multiple feeders 21, so that the operator can be accurately informed that the carrier tape 900 has been inserted into a feeder 21 other than the feeder 21 to which the supply of parts has been instructed.

In the embodiment described above, an example was described in which each feeder 21 was provided with an indicator lamp 85, but since a plurality of feeders 21 are not installed in the component supply section 20 at the same time, One indicator lamp 85 may be placed at a position that is easily visible to the operator.

Note that the tape insertion detection sensor 90 can also be used as the first sensor 65 that detects the boundary between the first carrier tape 900A and the second carrier tape 900B, and is limited to the one in the embodiment. isn't it.

In this way, the present invention is not limited to the configuration described in the above-described embodiments, and can take various forms without departing from the gist of the present invention as set forth in the claims. .
