When a predetermined amount is peeled from the peeling block 26, the end tape sensor 28 provided on the right side of the peeling block 26 detects the end of the end tape 10 and the rotation of the drive motor of the peeling paper take-up roll 27 is stopped to complete the setting. To do.

<Automatic Operation> The "automatic operation" of the taping device according to this embodiment will be described. When the user presses a start button (not shown), the taping device starts automatic operation. The cylinder 16 is conveyed from the previous process by the linear conveying means 15, and pushes out the work 14 whose forward movement is stopped at the cutting position 47 by the stopper 48 to the positioning stage 49 to perform left, right, front and rear positioning.
The work loading unit 18 is used for positioning the work 14
Is suction-held by a vacuum pad attached to the transport section, lifted up on the positioning stage 49, and then 9
Embossed part 1 of carrier embossed tape 4 by rotating 0 °
Stop on top of 7. After that, the transport unit of the work loading unit 18 drops onto the embossing unit 17 and then releases the suction by the vacuum pad, and loads the work 14 on the embossing unit 17 apart from the vacuum pad. After loading,
The upper part of the carrier embossed tape 4 (on the opening side of the embossed portion 17) is covered with the cover tape 19, and the carrier embossed tape 4 is sent below the thermal welding unit 20 by the pin sprockets 11a and 11b. The heater block 21 provided below the heat welding unit 20 is moved downward by the cylinder 39 and comes into contact with the cover tape 19, and the cover tape 19 is heat welded to the carrier embossing tape 4. Cover tape 19
The carrier embossed tape 4 having been heat-sealed is guided by the left and right and upper guide plates 22 and the lower guide plate 6, and is wound up on the storage reel 1 via the tape guide plate 9 which is vertically rotatable.

<End Tape Attaching Operation> “Adhesion operation of the end tape 10”, that is, “the end portion 8 of the carrier embossed tape 4 is stored by the end tape 10 in the reel 1
The operation of pasting on the core 31 ”will be described. When the sensor 41 provided on the tape guide plate 9 detects the tip portion 8, the fixing means 34 stops the advance of the carrier embossed tape 4 at the position where the tip portion 8 projects from the tape guide plate 9 by several tens of mm. The loading operation of the work 14 is continuously executed even after the advance of the carrier embossing tape 4 is stopped, and the carrier embossing tape 4 loaded with the work 14 is stored in the buffer section 7. When the carrier embossed tape 4 stops moving forward, the tape guide plate 9 rotates upward, and at the same time, the chuck 29 opens to open the end tape 10.
Grab The moving cylinder 30 moves to the right while the chuck 29 holds the end tape 1 and the end tape 1
0 stops in a state where it is peeled off from the release paper 23 leaving a few mm at the end. At this time, in order to remove the end tape 10, the moving cylinder 30 moves to the right, and at the same time, the drive motor of the release paper take-up reel 27 is rotated, and the release paper 23 winds the loose amount. The end portion 10 lifted up by the rotation of the tape guide plate 9 is brought into contact with the end tape 10 whose adhesive portion is exposed, whereby the end tape 10 and the tip portion 8 of the carrier embossed tape 4 are bonded.

After the bonding, the tape guide plate 9 descends downward and stops in a state where the tip end portion 8 and the right half unbonded portion of the end tape 10 are in contact with the core 31. Next, the vertical drive cylinder 33 lowers the tape adhering roller unit 32 located right above the core 31 and presses it against the end tape 10 arranged on the core 31. Further, a predetermined pressure is applied to push down the tape sticking rollers 32a and 32b, and the carrier embossing tape 4 and the end tape 10 and the core 31 and the end tape 10 are pressed to surely bond them. . After that, the vertical drive cylinder 33 raises the tape sticking roller unit 32 and returns it to the original position.

After the end tape 10 is attached to the storage reel 1 as described above, the rotation drive motor 35, which is the drive means of the storage reel 1, loses the extra carrier embossed tape stored in the buffer section 7. The storage reel 1 is rotated at a higher speed than in the steady state. The rotation drive motor 35 winds the carrier embossing tape 4 with a constant torque when the excess carrier embossing tape 4 is used up (that is, when the slack is removed and the drive carrier becomes linear). During the attaching operation of the end tape 10, the carrier embossing tape 4 loaded with the work 14 by the work loading unit 18 is stored in the buffer section 7. Rotary drive motor 3
No. 5 starts rotating the storage reel 1 at the same time when the tape sticking roller unit 32 rises and reaches the top dead center,
The carrier embossed tape 4 stored in the buffer section 7 is wound up at once. As soon as the carrier embossed tape 4 stored in the buffer section 7 disappears and the slackness disappears,
The lower guide plate 6 rotates upward and returns to the horizontal position to start continuous operation.

<Switching Operation of Storage Reels> The number of works 14 stored in the storage reel 1 becomes full, and the empty storage reels 5
The operation of switching to (the switching operation of the storage reel) will be described. The storage reel switching operation is performed when the sensor 37 detects that a predetermined number of works 14 are stored in the storage reel 1. This operation is roughly classified into "a cutting operation of the carrier embossing tape 4", "an operation of attaching the end of the cover tape 19 with the end tape 10", and "an operation of moving the storage reels 1 and 5".

First, the "cutting operation of the carrier embossing tape 4" will be described. When the sensor 37 detects that a predetermined number of works 14 are loaded in the embossed portions 17 of the carrier embossed tape 4 wound on the storage reel 1, the work loading unit 18 stops the work loading operation. When the work loading unit 18 is stopped, the works 14 manufactured in the previous step are stored on the linear transport means 15. The transport unit 11 keeps the carrier embossed tape 4 running even after the loading of the work 14 is stopped. The heat welding unit 20 has an embossed portion 17 in which the work 14 is loaded.
The cover tape 19 is heat-welded up to, but after the embossed portion 17 where the work 14 is not loaded, the cover tape 1
9 is not heat welded. Immediately after the embossed portion 17 to which the cover tape 19 is not heat-welded has passed the vacuum pad 40f that sucks the cover tape 19 in a vacuum and raises it by a certain amount, the transport unit 11 stops feeding the carrier embossed tape 4. After the transport unit 11 stops,
The vacuum pads 40e and 40f are cover tapes 1.
Only 9 is lifted and the cutting unit 40 moves onto the carrier embossing tape 4. Then, the lower blade 40b is lifted up by the cylinder 40c to cut only the carrier embossing tape 4. After the lower blade 40b cuts the carrier embossed tape 4, the cylinder 40c moves to the lower blade 4
0b is lowered. After that, the storage reel 1 winds only the cover tape 19 for the length of one round of the storage reel 1 which is full by winding. The cylinder 40c moves the lower blade 40b upward again to cut only the cover tape 19. The taping device according to the present embodiment controls the heat welding unit 20 to heat weld the front side (mounting shaft 43 side) of the cut position of the cover tape 19. Therefore, the cover tape 19 is heat-welded to the tip portion 8 of the carrier embossing tape 4, so that the operation of attaching the carrier embossing tape 4 to the core 31 of the storage reel 1 can be performed without any problem.

Next, the "operation for attaching the end of the cover tape 19 with the end tape 10" will be described. When the sensor 41 installed on the tape guide plate 9 detects the end of the cut cover tape 19, the fixing means 34 stops the forward movement of the cover tape 19 at a position several tens of mm before the tip of the tape guide plate 9. When the forward movement of the cover tape 19 is stopped, the tape guide plate 9 is rotated upward, and at the same time, the chuck 29 is opened and the end tape 10 is gripped.
The moving cylinder 30 moves to the right while the chuck 29 holds the end tape 10, and the end tape 10 is stopped in a state where it is peeled from the release paper 23 leaving a few mm at the end. At this time, in order to remove the end tape 10, the moving cylinder 30 moves to the right, and at the same time, the drive motor of the release paper take-up reel 27 is rotated, and the release paper 23 winds the loose amount. By bringing the end portion lifted upward by the rotation of the tape guide plate 9 into contact with the end tape 10 whose adhesive portion is exposed, the end tape 10 and the end portion of the cover tape are bonded.

After the bonding, the tape guide plate 9 is lowered,
It stops in the state where the end portion of the cover tape 19 and the unbonded portion of the right half of the end tape 10 are in contact with the cover tape 19 wound on the storage reel 1. Next, the vertical drive cylinder 33 lowers the tape adhering roller unit 32 located right above the core 31 and presses it against the end tape 10 arranged on the core 31. Further, a predetermined pressure is applied to push down the tape applying rollers 32a and 32b, and pressure is applied to surely bond the cover tape 19 and the end tape 10. After that, the vertical drive cylinder 33 raises the tape sticking roller unit 32 and returns it to the original position. By the above operation, the end portion of the cover tape 19 is attached to the circumference of the storage reel 1 by the end tape 10.

"Operation for moving storage reels 1 and 5"
Will be described. When the end portion of the cover tape 19 is sealed by the end tape 10, the cylinder 38 is
The storage reel 1 is moved in the axial direction of the rotary shaft 2. The storage reel 5 is also similarly moved by the cylinder 38, and is arranged at the place where the storage reel 1 was arranged, that is, on the extension (winding position) of the transport space 3. When the storage reel 5 is arranged at a predetermined position, the same operation as the "end tape attaching operation" is performed on the storage reel 5.

"Replacement work of the storage reel 1 which is full"
Will be described. The winding of the storage reel 1 is completed,
When the winding on the storage reel 5 is started, the taping device lights up and displays a signal tower (not shown). As a result, the taping device notifies the user that the winding of the storage reel 1 has been completed, and prompts the user to replace it with an empty reel. When the user depresses an exchange switch (not shown), the rotary drive motor 35 that is the power source of the storage reel 1 stops, and at the same time, the lower guide plate 6 rotates downward and starts to store the carrier embossed tape 4 in the buffer section 7. The user can safely replace the storage reel 1 whose rotation has stopped. When the user depresses the replacement switch again after the reels have been replaced, the rotation drive motor 35 starts rotating to rotate the storage reel 5. The rotary drive motor 35 is
The storage reel 5 is rotated at a higher speed than in the steady state until the carrier embossed tape 4 stored in the buffer section 7 is wound up. That is, the rotary drive motor 35 winds the carrier embossed tape 4 stored in the buffer unit 7 at a speed faster than the speed at which the sprockets 11 a and 11 b run the carrier embossed tape 4. When the carrier embossed tape 4 stored in the buffer portion 7 is used up, the lower guide plate 6 rotates upward to shift to a steady state, and the carrier embossed tape is wound on the storage reel 5.

In the taping device according to the present embodiment, the storage reel 5 automatically switched from the storage reel 1 by rotating the lower guide plate 6 and the tape guide plate 9.
The end tape 10 is attached to the core of the carrier embossing tape 4 and the carrier embossing tape 4 can be wound. Further, since the end tape 10 for sealing the end of the cover tape 19 is directly placed at the attachment position by the chuck 29 and completely adhered by the tape attachment roller unit 32, the seal is incomplete due to the influence of dirt or the like. It never happens. Further, since the operation of the lower guide plate 6 and the tape guide plate 9 is a simple rotational movement about the pivot, a complicated mechanism is not required.

[Second Embodiment] A second embodiment preferably implementing the present invention will be described. The taping device according to the present embodiment is similar to the taping device according to the first embodiment shown in FIGS. 1 and 2, and the carrier embossing tape 4 similar to that of the first embodiment shown in FIG. 3 is applied. . FIG. 4 is a diagram showing the configuration of the winding unit of the taping device according to the present embodiment. In the present embodiment, two more storage reels 5 are arranged in the axial direction of the rotating shaft 2 to form four reels, and since the number of storage reels is increased, it is not necessary to frequently perform reel replacement work. The labor of the user can be further reduced. In this embodiment,
In addition to the taping device of the first embodiment, only means (for example, a cylinder) for moving the storage reel 5 in the axial direction of the rotation shaft 2 may be further arranged. Therefore, a taping device that automatically performs a reel switching operation can be realized at low cost without complicating the structure.

The above embodiments are examples of preferred embodiments of the present invention, and the present invention is not limited to these. For example, the filled storage reel 1 may be released from the rotating shaft 2 without stopping the rotation drive motor 35 when replacing the storage reel.
