Tape splicing device

The present invention relates to a tape splicing device that sequentially feeds tapes and connects a tape to be fed first to a tape to be fed next.

Conventionally, an electronic component supply device is provided on the upstream side of the electronic component mounting device, and the electronic components are sequentially supplied to the electronic component mounting device by the electronic component supply device. For transporting electronic components, a carrier tape wound around a reel is used (for example, Patent Document 1). The carrier tape is provided with a large number of concave component storage parts arranged in the longitudinal direction of the carrier tape. Each of the component storage parts stores electronic components and is covered with a cover tape from above. (See Patent Document 1).

When the preceding carrier tape wound on the reel becomes small, the tip of the next carrier tape wound on the next reel for replacement is connected to the end of the preceding carrier tape with a connecting tape (Patent Document 1). reference). Thereby, a part can be supplied by making a plurality of carrier tapes into a continuous carrier tape (see Patent Document 1).

Japanese Patent No. 3591416

By the way, in the technique described in Patent Document 1, since the carrier tapes are manually connected, in order to replace the carrier tape, it is necessary to temporarily stop the feeding of the carrier tape. That is, the supply of electronic components is temporarily stopped. In order to improve the processing capacity of the downstream process, it is desired to supply electronic components continuously and at high speed, but there is a limit because the replacement of the carrier tape is a manual operation.

The present invention has been made in view of the above circumstances. The problem to be solved by the present invention is to enable the previous tape and the next tape to be mechanically connected without stopping the feeding of the tape.

In order to solve the above problems, a tape splicing device that sequentially feeds a tape and connects the next tape to the previous tape holds a plurality of reels around which the tape is wound, and sequentially transfers the reels to a predetermined tape. A reel feeder that intermittently feeds to a supply position; and a tape that is provided downstream of the supply position and that is first pulled out from a previous reel positioned at the supply position, and then positioned at the supply position A tape joining machine for joining the next tape pulled out from the next reel, and provided at a downstream side of the tape joining machine, until the previous tape and the next tape are joined by the tape joining machine. A path length adjusting unit that adjusts the path length of the tape to be short.
Other characteristics of the present invention will be made clear by the description and drawings described later.

According to the present invention, the preceding tape and the next tape can be mechanically connected without stopping the feeding of the previous tape and at a high speed, so that it is possible to cope with the speeding up of the downstream process.

It is drawing which showed the process which positioned the front-end | tip of the following tape on the tape bonding machine by the drawing | feeding-out part.

At least the following matters will be apparent from the description and drawings described below.
A tape splicing device that sequentially feeds tapes and connects the next tape to the previous tape, holds a plurality of reels around which the tapes are wound, and intermittently feeds these reels sequentially to a predetermined supply position. A reel feeder, provided downstream of the supply position and first pulled out from the previous reel positioned at the supply position and next extracted from the next reel positioned at the supply position A tape joining machine for joining the tapes, and a downstream side of the tape joining machine, and the path length of the previous tape is shortened until the previous tape and the next tape are joined by the tape joining machine. A tape splicing device including a path length adjusting unit to be adjusted becomes apparent.

As described above, when the previous tape and the next tape are bonded by the tape bonding machine, the path length of the previous tape is adjusted to be shorter by the path length adjusting unit provided on the downstream side of the tape bonding machine. Even when the previous tape is positioned on the tape bonding machine, it is not necessary to stop the feeding of the previous tape. Therefore, the previous tape and the next tape can be mechanically connected, and the tape feeding by the tape splicing device can be continuously and at a high speed.

Preferably, after the previous tape and the next tape are joined by the tape joining machine, the path length adjusting unit adjusts the path length of these tapes to be longer.

As described above, since the path length between the previous tape and the next tape joined thereto is adjusted to be longer by the path length adjusting unit, the path length of the next tape and the next tape are joined at the next time. Can be prepared for a short adjustment by the path length adjustment unit.

Preferably, the tape splicing device is provided on the downstream side of the tape bonding machine, and feeds a tape drawn from a reel located at the supply position, and downstream of the first tape feeding unit. A second feeding section that is provided on the side and feeds the tape fed by the first feeding section downstream; a next reel that is provided in the reel feeder for each of the plurality of reels and is next located at the supply position; A feeding section for feeding the next tape to the tape bonding machine, and the path length adjusting section is provided between the first feeding section and the second feeding section, Adjust the tape path length to the second feed section.

As described above, since the path length adjusting portion is provided between the first feeding portion and the second feeding portion, the tape feeding speed by the first feeding portion and the tape feeding speed by the second feeding portion are not equal. Even so, the path length of the tape from the first feeding section to the second feeding section is adjusted by the path length adjusting section. Therefore, when the entire previous tape is pulled out from the previous reel positioned at the supply position first, and the next reel is fed to the supply position by the reel feeder, the previous tape is fed to the tape joining machine by the first feeding section. It is possible to feed the previous tape downstream by the second feeding portion while positioning the tape. Further, when the next tape is fed from the next reel sent to the supply position by the feeding unit, the previous tape is positioned by the first feeding unit on the tape joining machine, and the previous tape is moved by the second feeding unit. Can be sent downstream. Then, the previous tape and the next tape can be joined by the tape joining machine while feeding the previous tape by the second feeding unit. Therefore, the previous tape and the next tape can be mechanically connected, and the tape can be fed continuously and at a high speed.

Preferably, while the first feeding portion stops the feeding of the previous tape in a state where the end of the previous tape pulled out from the previous reel positioned at the supply position is positioned at the tape joining machine. When the second feeding portion feeds the previous tape, the reel feeder sends the next reel to the supply position, and the feeding portion joins the leading end of the next tape from the next reel to the tape. The tape joining machine joins the end of the previous tape and the tip of the next tape.

According to the above, while the first feeding unit stops the feeding of the previous tape in a state where the end of the previous tape pulled out from the previous reel is positioned in the tape bonding machine, the second feeding unit is used for the previous tape. The path length of the previous tape is adjusted to be shorter by the path length adjustment unit. Therefore, it is not necessary to stop the feeding of the previous tape by the second feeding unit.
Also, the reel feeder feeds the next reel to the supply position, and the feeding section feeds the tip of the next tape from the next reel to the tape joining machine, thereby matching the end of the previous tape with the tip of the next tape. It can be in the state. Therefore, the end of the previous tape and the tip of the next tape can be joined by the tape joining machine.

More preferably, after the joining operation of the tape joining machine, after the first feeding section sends the previous tape and the next tape at a tape feeding speed higher than the tape feeding speed by the second feeding section, The first feeding section feeds the next tape at a feeding speed equal to the tape feeding speed by the second feeding section.

When the first feeding section feeds the previous tape and the next tape at a tape feeding speed higher than the tape feeding speed by the second feeding section, the path length of these tapes is adjusted longer by the path length adjusting section. It is possible to prepare for the connection between the tape and the next tape.

Preferably, the tape splicing device includes a control unit that controls the reel feeder, the first feeding unit, the second feeding unit, the tape joining machine, and the feeding unit, and an upstream side of the tape joining machine. A tape detection unit that detects the tape, and the control unit causes the first tape drawn from the previous reel positioned at the supply position to be sent to the first feeding unit, and A normal feeding process in which the preceding tape is fed to the second feeding unit at a feeding speed equal to the tape feeding speed by the one feeding unit, and the end of the preceding tape is detected by the tape detection unit during the normal feeding process. Then, after the first tape is fed to the first feeding unit until the end of the previous tape is located at the tape joining machine, the first feeding is performed without stopping the second feeding unit. When the end of the previous tape is detected by the tape detector during the first positioning process and the normal feeding process, the next reel adjacent to the previous reel positioned at the supply position is supplied. A reel feeding process for feeding the reel to the position, a tape feeding process for feeding the next tape drawn from the next reel to the feeding unit after the reel feeding process, and a tape feeding process. When the leading end of the next tape is detected by the tape detection unit, the feeding unit is stopped after feeding the next tape to the feeding unit until the leading end of the next tape is positioned at the tape joining machine. The second positioning process, and after the first positioning process and the second positioning process, A joining process for joining an end and an end of the next tape, and the first tape and the next tape to the first feeding part at a feeding speed higher than the tape feeding speed by the second feeding part after the joining process. A high-speed feed process for feeding and a deceleration process for decelerating the tape feed speed by the first feed section to the tape feed speed by the second feed section after the high-speed feed process are executed.
More preferably, in the first positioning process, the control unit stops the first feeding unit in a state where the first feeding unit has a holding force of the previous tape.
The control unit repeatedly executes the normal feeding process, the first positioning process, the reel feeding process, the tape feeding process, the second positioning process, the joining process, the high-speed feeding process, and the deceleration process. .

According to the above, the reel feeder, the first feeding portion, the front second feeding portion, the tape joining machine and the feeding portion are controlled by the control portion, so that the tape feeding without stopping the tape feeding by the second feeding portion can be performed. And the next tape can be automatically connected to the previous tape.

Preferably, the tape splicing device described above further includes a tape cutting machine that is provided on the downstream side of the feeding portion and on the upstream side of the tape bonding machine and cuts the tape.
More preferably, the tape cutting machine cuts the previous tape before the end of the previous tape pulled out from the previous reel positioned at the supply position reaches the tape joining machine.

According to the above, the end portion of the previous tape is cut by the tape joining machine, so that the portion with the curl generated by being wound on the reel can be removed. Therefore, the previous tape and the next tape can be favorably joined.

Preferably, the path length adjusting unit is provided on the downstream side of the tape bonding machine, and includes a fixed roller and a dancer roller on which the tape to be fed is hung, and the fixing is performed according to the tension of the tape from which the dancer roller is fed. Contact and separate from the roller.

According to the above, if the tape feeding speed by the first feeding part is lower than the tape feeding speed by the second feeding part, the dancer roller approaches the fixed roller and the tape path length becomes short. Further, if the tape feeding speed by the first feeding section is higher than the tape feeding speed by the second feeding section, the dancer roller is separated from the fixed roller, and the path length of the tape becomes long. If the tape feeding speed by the first feeding section is equal to the tape feeding speed by the second feeding section, the tape path length is maintained.

The

dancer rollers

72 a, 72 b, 72 c, 72 d and the moving body 73 move up and down according to the balance between their own weight and the tension of the carrier tape 2. Accordingly, the path length of the carrier tape 2 is adjusted by the path length adjusting unit 70 in accordance with the difference between the tape feeding speed by the first feeding unit 50 and the tape feeding speed by the second feeding unit 60.

Specifically, if the feeding speed of the carrier tape 2 by the second feeding section 60 is higher than the feeding speed of the carrier tape 2 by the first feeding section 50, the tension of the carrier tape 2 becomes strong, so the

dancer roller

rollers

71a, 71b, 71c, 71d due to ascending, and the path length of the carrier tape 2 is gradually shortened. If the feeding speed of the carrier tape 2 by the second feeding section 60 is lower than the feeding speed of the carrier tape 2 by the first feeding section 50, the tension of the carrier tape 2 becomes weak, so the moving body 73 and the

dancer roller

72a, 72b, 72c, and 72d move away from the fixed

rollers

71a, 71b, 71c, and 71d due to lowering, and the path length of the carrier tape 2 is gradually increased. If the feeding speed of the carrier tape 2 by the second feeding section 60 is equal to the feeding speed of the carrier tape 2 by the first feeding section 50, the tension of the carrier tape 2 is constant, so the moving body 73 and the

dancer rollers

72a, 72b, 72c and 72d do not move up and down, and the path length of the carrier tape 2 is maintained.
If the weights of the

dancer rollers

72a, 72b, 72c, 72d and the moving body 73 are too heavy, adjustment is performed by providing a counterweight.

Arranged on the side. The second tape sensor 98 detects the carrier tape 2. For example, a photoelectric sensor (comprising a projector and a light receiver), a proximity sensor, a contact sensor, or a limit switch is adopted as the second tape sensor 98. The chip sensor 99 detects the IC chip 6. For example, the chip sensor 99 determines the presence or absence of the IC chip 6 in the housing recess 5. These

sensors

As shown in FIGS. 1 and 2, a control unit 15 is provided above the reel feeder 30. The control unit 15 includes a computer (for example, a programmable logic controller), a motor driver, a hardware interface, and the like. As shown in the block diagram of FIG. 5, output signals of the first tape sensor 89, the second tape sensor 98, and the chip sensor 99 are input to the control unit 15. For example, when the carrier tape 2 is detected by the

tape sensors

tape sensors

89 and 98 are at a high level, and when the carrier tape 2 is not detected by the

tape sensors

The control unit 15 controls the driving

devices

33, 45, 54, 62, 83, and 91. That is, the control unit 15 operates the

drive devices

33, 45, 54, 62, 83, 91 at a predetermined timing, controls the speed of the

drive devices

33, 45, 54, 62, 83, 91, The

apparatus

33, 45, 54, 62, 83, 91 is stopped.

Hereinafter, the operation of the tape splicing device 10 will be described.
The tape splicing device 10 repeats the normal feeding operation and the switching operation alternately. In the normal feeding operation, the carrier tape 2 remains on the supply source reel 1 and the carrier tape 2 drawn from the supply source reel 1 is guided to the feed roller pair 61 of the second feed unit 60 and the carrier tape. The operation when 2 is drawn downstream. In the switching operation, all the carrier tape 2 is pulled out from the supply reel 1 and the supply reel 1 becomes empty, the next reel 1 adjacent to the supply reel 1 is sent to the supply position P, and the next The operation when the next carrier tape 2 drawn out from the reel 1 is drawn out downstream. Since the switching operation is intermittently performed, the reels 1 are sequentially and sequentially sent to the supply position P.

First, the normal feeding operation of the tape splicing device 10 will be described.
During the normal feeding operation, the control unit 15 maintains the driving device 83 of the tape cutting machine 80 and the driving device 91 of the tape bonding machine 90 in a stopped state. If it does so, it will stand by in the position where the upper blade 81 and the lower blade 82 of the tape cutting machine 80 left | separated mutually, and the tape joining machine 90 will also wait. Further, the control unit 15 maintains the driving device 33 of the reel feeder 30 in a stopped state, the supply source cassette 34 is located at the supply position P, and the standby cassette 34 is located at a position other than the supply position P.

During the normal feeding operation, the control unit 15 cuts off the electric power of the driving device 45 and the driving device 45 enters a free state without holding force, so that the driving roller 42 follows the feeding of the carrier tape 2. Further, the control unit 15 controls the driving device 54 of the first feeding unit 50 at a constant speed, and the feeding speed of the carrier tape 2 by the first feeding unit 50 (particularly, the roller pair 51, 53) is kept constant. Similarly, the control unit 15 controls the driving device 62 of the second feeding unit 60 at a constant speed. Then, the carrier tape 2 is steadily sent downstream from the second feeding part 60. Here, the feed speed of the carrier tape 2 by the first feed section 50 and the feed speed of the carrier tape 2 by the second feed section 60 (particularly the feed roller pair 61) are controlled equally by the control section 15. This feed speed is represented as V1. The control unit 15 may control the drive device 45 of the active feeding unit 40 at a constant speed during the normal feeding operation. In this case, the feeding speed of the carrier tape 2 by the active feeding unit 40 (particularly, the driving roller 42). Is controlled to be equal to the speed V1 by the control unit 15.

Since the feeding speed of the carrier tape 2 by the first feeding section 50 and the feeding speed of the carrier tape 2 by the second feeding section 60 are equal, the moving body 73 and the

dancer rollers

72a, 72b, 72c, 72d are more than the highest position in the movable range. It stops at the lower position (for example, near the lowest position).

Further, the carrier tape 2 is detected by the

tape sensors

89 and 98, and an output signal (high level) to that effect is output to the control unit 15 by the

tape sensors

89 and 98.

Next, the switching operation of the tape splicing device 10 will be described with reference to the flowchart of FIG. In the following description, the code of the previous carrier tape 2 is 2A, and the code of the next carrier tape 2 is 2B.

The switching operation is started when the end of the previous carrier tape 2A crosses the first tape sensor 89. That is, the control unit 15 monitors the output signal of the first tape sensor 89 during the normal feeding operation (step S1), and the switching operation starts when the end of the previous carrier tape 2A is detected by the first tape sensor 89. (Step S1: YES). The controller 15 continues to control the driving device 62 of the second feeding unit 60 at a constant speed during the switching operation, and the previous carrier tape 2A is fed out by the second feeding unit 60 at the speed V1.

And the control part 15 drives the drive device 83 of the tape cutting machine 80 (step S2), and the tape cutting machine 80 cuts off the terminal side 2A1 of the previous carrier tape 2A (refer FIG. 7). Since the cut-off portion 2A1 is wound around the center of the supply reel 1, the portion 2A1 is rounded with a large curvature, and the curvature of the remaining portion of the carrier tape 2A is small. When the driving device 45 is controlled at a constant speed during the normal feeding operation, the control unit 15 cuts off the power of the driving device 45 in step S2, and the driving device 45 enters a free state without holding force.

Subsequently, the control unit 15 monitors the output signal of the second tape sensor 98 (step S3). When the end of the previous carrier tape 2A is detected by the second tape sensor 98 (step S3: YES), the end of the carrier tape 2A is positioned at the joining position of the tape joining machine 90 (see FIG. 8). ), The control unit 15 controls the driving device 54 of the first feeding unit 50 at a constant speed by a predetermined amount (step S4). When the end of the carrier tape 2A is located at the joining position of the tape joining machine 90, the control unit 15 stops the driving device 54 (step S4).

Here, even if the driving device 54 of the first feeding unit 50 is stopped in step S4, since the power is supplied to the driving device 54 by the control unit 15, the driving device 54 is in a holding state having a holding force and is driven. The device 54 does not move due to external force. Therefore, even if the previous carrier tape 2A is pulled by the second feeding portion 60, the carrier tape 2A is not pulled out from the roller pairs 51 to 53 of the first feeding portion 50. In addition, since the previous carrier tape 2A is fed downstream by the second feeding portion 60, the moving body 73 and the

dancer rollers

72a, 72b, 72c, 72d are raised, and the path length of the carrier tape 2A is gradually shortened. Thus, since the path length of the carrier tape 2A has been adjusted to be long before step S4, the carrier tape 2A can be sent by the second feeding section 60 on the downstream side of the path length adjustment section 70 even after step S4. it can. Note that the moving body 73 and the

dancer rollers

72a, 72b, 72c, and 72d continue to rise until the process of step S10 described later.

Subsequently, the control unit 15 operates the driving device 33 of the reel feeder 30 by a predetermined amount (step S5), and the carriage 32 and the cassette 34 are moved by the driving device 33 by the interval between the adjacent cassettes 34. As a result, the next cassette 34 arranged next to the supply source cassette 34 containing the empty supply source reel 1 is positioned at the supply position P by the drive device 33 (see FIG. 9). The processing in step S5 is after the end of the previous carrier tape 2A is detected by the first tape sensor 89 (step S1: YES), and the next carrier tape 2B is fed out (step S6 described later). It is only necessary to be performed before the process.

When the next cassette 34 is moved to the supply position P, the drive roller 42 of the supply unit 40 previously positioned at the supply position P is blocked from the drive device 45, and the supply unit 40 becomes inactive. On the other hand, the driving roller 42 of the next feeding unit 40 adjacent to the adjacent unit is connected to the driving device 45, and the next feeding unit 40 becomes active.

Subsequently, the control unit 15 operates the driving device 45 of the next active feeding unit 40 (step S6), and the driving roller 42 of the next active feeding unit 40 is driven by the driving device 45. As a result, the next carrier tape 2B is fed by the drive roller 42 of the next active feed section 40, and the tip of the next carrier tape 2B moves toward the end of the previous carrier tape 2A.

Subsequently, the control unit 15 monitors the output signal of the second tape sensor 98 (step S7). Then, when the leading end of the next carrier tape 2B is detected by the second tape sensor 98 (step S7: YES), the controller 15 causes the leading end of the carrier tape 2B to be positioned at the joining position of the tape joining machine 90. Controls the driving device 45 of the next active feeding unit 40 at a constant speed by a predetermined amount (step S8). And if the front-end | tip of the carrier tape 2B is located in the joining position of the tape joining machine 90, the control part 15 will stop the drive device 45 (step S8). As a result, the end of the previous carrier tape 2A and the end of the next carrier tape 2B are brought into contact with each other (see FIG. 10). Since the previous carrier tape 2A has been cut (see step S2), the end of the previous carrier tape 2A and the leading end of the next carrier tape 2B become good.

Subsequently, the control unit 15 operates the drive device 91 of the tape bonding machine 90 (step S9), and the tape bonding machine 90 is driven by the drive device 91. Then, the tape bonding machine 90 performs a bonding operation to bond the end of the previous carrier tape 2A and the tip of the next carrier tape 2B.

Subsequently, the control unit 15 cuts off the electric power of the driving device 45, and the driving device 45 enters a free state with no holding force. At the same time, the control unit 15 controls the driving device 54 of the first feeding unit 50 at a constant speed (step S10). Then, the next carrier tape 2B is sent downstream by the first feeding unit 50 following the previous carrier tape 2A. The feeding speed of the next carrier tape 2B by the first feeding section 50 is kept constant, but the feeding speed V2 is higher than the feeding speed V1 of the

carrier tapes

2A and 2B by the second feeding section 60 by the control section 15. Be controlled. Accordingly, the moving body 73 and the

dancer rollers

72a, 72b, 72c, 72d are lowered, and the path lengths of the

carrier tapes

2A, 2B are gradually increased.
In step S10, the control unit 15 may control the drive device 45 of the next active feeding unit 40 at a constant speed. In this case, the feed speed of the next carrier tape 2B by the next active feeding unit 40 is first. It is equal to the feed speed V2 of the

carrier tapes

2A and 2B by the feed section 50.

When a predetermined time has elapsed from the start of constant speed control of the driving device 54 of the first feeding unit 50, or when the carrier tape 2B is fed by a predetermined amount from the start of constant speed control of the driving device 54, or When the

dancer rollers

72a, 72b, 72c, 72d are lowered to a predetermined position and the moving body 73 and the

dancer rollers

72a, 72b, 72c, 72d are detected by the sensors, the control unit 15 drives the drive unit 54 of the first feeding unit 50. Is decelerated (step S11). The control unit 15 controls the driving device 54 of the first feeding unit 50 at a constant speed, and the feeding speed of the next carrier tape 2B by the first feeding unit 50 is controlled by the control unit 15 by the carrier tape 2A by the second feeding unit 60. , 2B is controlled to be equal to the feed speed V1. Therefore, the lowering of the moving body 73 and the

dancer rollers

72a, 72b, 72c, 72d stops.
In addition, when the control part 15 carries out the constant speed control of the drive device 45 in step S11, the control part 15 synchronizes with the deceleration of the drive apparatus 54, and also decelerates the drive apparatus 45. The next carrier tape 2B feed speed is equal to the speed V1.

When the drive device 54 of the first feeding unit 50 is decelerated in the process of step S11, the switching operation of the tape splicing device 10 is completed, and the next normal feeding operation of the tape splicing device 10 is started. In the next normal feeding operation, the next carrier tape 2B is steadily paid out.

Since the tape splicing device 10 alternately repeats the normal feeding operation and the switching operation, the carriage 32 intermittently moves to the right in FIG. 2, so that the plurality of reels 1 shown in FIG. Sent to. When the leftmost reel 1 is positioned at the supply position P and the carrier tape 2 is fed from the leftmost reel 1 by the normal feeding operation of the tape splicing device 10, the other reels in which the operator is empty 1 is replaced with a new reel 1. That is, the operator stores the new reels 1 in the cassettes 34 (excluding the leftmost cassette 34), pulls out the carrier tape 2 from the new reels 1, and sets the tips of the carrier tapes 2 respectively. It is sandwiched between the driven roller 41 and the driving roller 42 of the feeding unit 40 (except the leftmost feeding unit 40).

Then, after the entire carrier tape 2 is pulled out from the leftmost reel 1, the moving direction of the carriage 32 in step S5 of the switching operation of the tape splicing device 10 is leftward in FIG. Thereafter, the tape splicing device 10 alternately repeats the normal feeding operation and the switching operation, so that the carriage 32 intermittently moves to the left in FIG. 2, so that the reel 1 is fed to the supply position P in order from left to right. When the rightmost reel 1 is positioned at the supply position P and the carrier tape 2 is fed from the rightmost reel 1 by the normal feeding operation of the tape splicing device 10, the operator becomes empty. The reel 1 is replaced with a new reel 1.
Thereafter, the intermittent movement of the carriage 32 to the right and the intermittent movement of the carriage 32 to the left are alternately repeated.

The above embodiment has the following effects and advantages.
(1) Since the path length adjusting unit 70 is provided between the first feeding unit 50 and the second feeding unit 60 each having a drive source, the tape feeding speed and the second feeding of the first feeding unit 50 The tape feeding speed of the part 60 can be made different. Accordingly, while the carrier tape 2 is fed by the second feeding section 60, the previous carrier tape 2 is cut (see step S2), the previous carrier tape 2 is positioned (see step S4), and the reel 1 is fed (see step S5). The next carrier tape 2 can be fed and positioned (steps S6 to S8), and the previous carrier tape 2 and the next carrier tape 2 can be joined (step S10) by the tape splicing device 10. That is, the operation of the tape splicing device 10 is automatically controlled by the control unit 15 without stopping the supply of the carrier tape 2 to the downstream process, in other words, the supply of the IC chip, because the path length adjusting unit 70 is provided. Can now. As a result, the IC chips can be supplied continuously and at high speed, and the high-speed processing in the downstream process is also supported.

That is, the plurality of carrier tapes 2 can be fed one after another without interruption.

(3) The work burden on the worker is reduced. That is, when the rightmost cassette 34 or the leftmost cassette 34 is located at the supply position P, it is only necessary to replace the empty reel 1.

(4) When the previous carrier tape 2 is cut by the tape cutting machine 80, the end of the previous carrier tape 2 and the leading end of the next carrier tape 2 are easily abutted, and these ends are joined well. be able to.

(5) Since the moving body 73 and the

dancer rollers

72a, 72b, 72c, 72d are lowered by the carrier tape 2 being fed at a high speed by the first feeding unit 50 in step S10, it is possible to prepare for the next switching operation. .
