There is a chip component supply system that continuously supplies chip components by running a tape fixed and covered (hereinafter referred to as chip component tape) with a top tape 22 at a constant speed with a sprocket.
[0003]
In such a chip component supply system, the supplied chip component tape is wound on a standard reel of a common size. Therefore, in an assembly site using a large number of chip components of the same type, one supplied chip component tape is required. Is insufficient and often requires many pieces.
[0004]
In such a case, in order to continuously and smoothly supply the chip components and increase the productivity at the assembly site, a plurality of supplied chip component tapes are connected in advance by the connection tape 23 as shown in FIG. The required number of chip components are connected. Note that such connection using a connection tape is performed using a jig.
[0005]
When connecting two supplied chip component tapes, the leading ends of the supplied chip component tapes cannot be connected as shown in FIG. Therefore, there is no other method than connecting the rear end of the supplied chip component tape (referred to as a chip-receiving component tape) and the leading end of the connected chip component tape (referred to as a connected chip component tape).
[0006]
Further, conventionally, it is obliged that a bar code composed of a code specified by the EIAJ standard is attached to the chip component tape.
[0007]
[Problems to be solved by the invention]
As described above, the connection between the tapes in the conventional chip component supply system connects the rear end of one chip component tape and the front end of the other chip component tape with a jig. There is a problem that the connection work takes a long time because the time required to protrude the ends is long, and therefore, the labor productivity is low.
[0008]
Conventionally, a bar code is attached to the chip component tape. However, a wrong type of the bar code causes the different types of chip component tapes to be connected to each other. There was a problem.
[0009]
Therefore, the present invention has a problem in a chip component tape winding system that can reliably perform connection between chip component tapes in a short time and that does not cause erroneous connection due to a bar code.

A take-up reel for connecting a chip component tape wound on a reel to wind a chip component tape of a required length, and first and second intermediate members provided between the supply reel and the take-up reel. The first and second intermediate reel units each include a reverse winding motor and an intermediate reel engaged with a rotation shaft of the motor, and each of the reverse winding motor and each intermediate reel. When the reverse winding motor rotates, the intermediate reel also rotates, and when each reverse winding motor stops, each intermediate reel idles, and the first and second intermediate reel portions are wound. Taking out the chip component tape from the supply reel, setting the taken chip component tape in the same direction as the supply reel, and connecting the chip component tapes wound on a plurality of supply reels, and winding the tape. That is, the reels are sequentially wound up.
[0011]
When the supply reel is set at a predetermined position, the type of the chip component tape wound on the take-up reel and the supply reel is checked; the type of the chip component tape is checked using a bar code. Chip component tape winding system.
[0012]
[Action]
The chip component tape winding system having the above-described basic configuration operates as follows. Assuming that one cycle is from the time when the two chip component tapes are connected by the jig to the time when the next connection is made, the chip component tape of the set supply reel is rotated in the same direction as the winding direction in a certain n-th cycle. That is, it is rotated in the opposite direction to the take-up reel, wound up on the intermediate reel, the rear end of the wound chip component tape is taken out, and the connected chip wound up on this rear end and the take-up reel Connect the end of the component tape with the jig.
[0013]
In the next (n + 1) -th cycle, the intermediate reel connected to the chip component tape of the take-up reel is idled, so that the supply chip component tape wound in the n-th cycle is wound on the take-up reel.
[0014]
During this (n + 1) -th cycle, another supply reel on which the supplied chip component tape to be connected next is wound is set, and is wound on another intermediate reel by driving a motor.
Repeat the above operation for the number of chip component tapes to be connected.
[0015]
As described above, during one cycle, the winding of the already connected chip component tape and the reverse winding for the trailing end of the next connected chip component tape are performed simultaneously, so that the time required for connection is reduced. Is done.
[0016]
At the end of each cycle, the winding and the reverse winding are finished at the same time, and the leading and trailing ends of both chip component tapes come out. And the operation of attaching the leading end of the next connection chip component tape to the other intermediate reel. Therefore, labor productivity is high.
[0017]
Also, by installing the reel sensor, the motor is operated only when the sensor detects the setting of the reel, so that the operation of the system is not wasted and the operator is prompted to set the reel. Increase efficiency.
[0018]
Further, in the chip component tape winding system in which a bar code reader is attached to the above configuration, the sequencer controls so that the motor is not operated when the bar codes of the take-up reel and the supplied chip component tape do not match. This can prevent an error of connecting chip component tapes having different barcodes.

[0037]
Hereinafter, the overall operation of this embodiment will be described with reference to the flowchart of FIG. In FIG. 3, the take-up reel unit 2, the first and second intermediate reel units 3, 4, the supply reel set unit 5, and the reel detection sensors 9, 10 are represented by squares for simplicity. This is indicated by a symbol surrounded by.
[0038]
(1) First, the power of the chip component tape winding system is turned on (step ST1). At this time, the motors 3a and 4a of the take-up reel unit 2 and the first and second intermediate reel units 3 and 4 are off (that is, in a state where they can idle).
(2) The take-up reel 2b is set on the take-up reel section 2 (step ST2). Then, the reel detection sensor 9 detects this and sends a reel-on signal to the sequencer 7.
[0039]
(3) The supply reel 5c on which the supplied chip component tape 5a is wound is set in the supply reel setting section 5 (step ST3). Then, the reel detection sensor 10 detects this, and sends a reel-on signal to the sequencer 7.
[0040]
(4) Next, the barcode symbols on the reels 2b and 5c of the take-up reel unit 2 and the supply reel set unit 5 are detected by the barcode reader 6b and sent to the POT 6b. The POT 6b compares both bar code signals, sends an OK signal to the sequencer 7 if they match, and displays an NG signal to the sequencer 7 if they do not match (step ST4).
[0041]
(5) If the bar code symbols match, the tip of the supplied chip component tape 5a set in the supply reel set section 5 is attached to the intermediate reel 3b of the first intermediate reel section 3, and the take-up reel section 2 and the The motors 2a, 3a (or 4a) of the first intermediate reel section 3 are started to rotate (step ST5).
[0042]
In step ST5, the supplied chip component tape 5a of the supply reel set unit 5 is wound clockwise around the intermediate reel 3b of the first intermediate reel unit 3. Then, in the first step ST5, the take-up reel 2b of the take-up reel unit 2 simply rotates, but from the second time, the chip component tape is transferred from the idle intermediate reel 4b of the second intermediate reel unit 4 5a is wound around the take-up reel 2b of the take-up reel unit 2.
[0043]
FIG. 4 shows the operation status of step ST5 after the second time. That is, the intermediate reel 3b rotates clockwise to reversely wind the supplied chip component tape 5a, and at the same time, the intermediate reel 4b of the second intermediate reel unit 4 which previously wound the supplied chip component tape 5a spins idle. Then, the chip component tape 5a is wound by the winding reel unit 2.
[0044]
(6) In step ST4, if the barcode signals do not match, the chip component tape reels 2b and 5c set on the take-up reel unit 2 and the supply reel set unit 5 are checked and set incorrectly. The reel is replaced with a correct reel (step ST6).
[0045]
(7) At the end of the operation in step ST5, the supplied chip component tape 5a is completely wound around the intermediate reel 3b, and the rear end of the tape 5a comes out. At the same time, the take-up reel 2b finishes winding the chip component tape 5a of the intermediate reel 4b, and the tip of the chip component tape 5a comes out.
[0046]
(8) Then, the motor 2a and the motor 3a are stopped (step ST6), and the front end of the chip component tape 5a of the take-up reel 2b and the rear end of the chip component tape 5a of the intermediate reel 3b are fixed by the jig 1. The connection is made with a connection tape 23 (see FIG. 5). Also, the empty reel of the supply reel set section 5 is removed (step ST7).
[0047]
(9) The supply chip component tape 5a to be connected next is set on the supply reel set section 5 (step ST8).
(10) The bar code symbols of the take-up reel unit 2 and the supply reel set unit 5 are compared (step ST9). If the barcode signals do not match, the chip component tape 5a wound around the mounted supply reel 5c is checked, and the wrong reel is removed and replaced with a correct reel (step ST10).
[0048]
(11) If the bar code signals match, the tip of the chip component tape 5a of the supply reel set unit 5 is attached to the intermediate reel 4b of the second intermediate reel unit 4, and then the motor 2a of the take-up reel unit 2 is turned on. The motor 4a of the second intermediate reel unit 4 is rotated in a clockwise direction, respectively. At this time, the motor 3a of the first intermediate reel unit 3 is kept stopped (that is, the intermediate reel 3b can idle).
[0049]
(12) As a result, the take-up reel 2b winds up the chip component tape 5a of the intermediate reel 3b, and at the same time, the intermediate reel 4b reversely winds the supplied chip component tape 5a (step ST11).
[0050]
(13) At the end of the operation in step ST11, the ends of the chip component tapes 5a of the take-up reel 2b and the intermediate reel 4b come out. Here, the motor 2a and the motor 4a are stopped, and the ends of the chip component tapes 5a of the take-up reel 2b and the intermediate reel 4b are connected (step ST12).
[0051]
(14) If the connection of the same type of chip component tape 5a is to be continued, the process returns to step ST3 and the above operation is repeated. Therefore, the supplied chip component tapes 5a as many as the number of repetitions are connected and wound on the take-up reel 2b of the take-up reel unit 2.
[0052]
(15) When shifting to the connection of another type of chip component tape 5a, the process jumps to step ST2, sets a new take-up reel 2b on the take-up reel unit 2, and repeats the above operation.
[0053]
