42 is a stator of the proximity switch, and 43 is a drive means for pushing the slide plate 16 of the cassette.

The actual cassette stock section 32 is shown in FIGS. 3 and 4.
As shown in the figure, a frame in which a large number of actual cassettes 6a can be stored in a stacked state, and an actual cassette 6a.
Four hooks 44 for hooking both protruding edges 7, 7...
..., an air cylinder 45 that moves the hooks 44 up and down, and an air cylinder 46 that opens and closes the hooks 44.... The frame has four vertical columns 47... In the figure, 48 is a link device, and the air cylinder 46 has a hook 44 on one side,
44 is opened and closed directly, and the hooks 44, 44 on the other side are opened and closed via this link device 48. Reference numeral 49 denotes rails having an L-shaped cross section, and two rails 49 are provided in parallel astride both the real cassette stock section 32 and the empty cassette stock section 33. A cassette is placed on these two rails 49, 49.

This real cassette stock section 32 supplies real cassettes in the following manner. First, as shown in FIG. 4, the hooks 44 hook the lowermost real cassette 6a, thereby holding the stacked real cassettes 6a in the air. Next, hook 4
4... is lowered and opened, the entire actual cassette 6a... is once lowered onto the rails 49, 49. After this, when the hook 44... is raised and closed between the lowermost real cassette 6a and the second real cassette 6a, the second real cassette 6a is hooked, and the second real cassette 6a is hooked.
The actual cassettes 6a of the higher stages are held hollow again. The lowered lowermost real cassette is positioned by a positioning pin 40 (see FIG. 3) provided on the real cassette stock section 32. The air cylinder 41 has a positioning pin 40 protruding so that it can be positioned when lowering the actual cassette 6a. In this way, the bottom cassette 6
You can now use the tape stored in a.

The empty cassette stock section 33 is shown in FIGS. 3 and 5.
As shown in the figure, the frame includes a frame in which empty cassettes 6b can be stored in a stacked state, four supports 50 and a lift 51 that support the stacked empty cassettes 6b. The frame consists of 4 vertical pillars 5
Has 2. The support 50 is swingably supported on a horizontal shaft 53. Since the center of gravity of the support 50 is off from the axis, the center of gravity is at the lowest position,
In other words, it is stabilized in a state directly below the shaft 53. In this stable state, the protruding edge 7 of the empty cassette 6b
Corners 54 for receiving are directed towards the inside of the frame. Therefore, the corner 54 receives the force from below.
Even if the corner 54 turns upward once, once the force is removed, the corner 54 automatically returns to its original state and turns inward. Reference numeral 55 denotes a stopper which receives the long side of the support 50 so that the corner 54 of the support 50 does not fall below its stable position (the position shown in FIG. 5).

Empty cassettes are sent to this empty cassette stock section from the actual cassette stock section. This situation will be explained using FIG. 6, and the movement of the taping device related thereto will also be explained. When the tape in the lowest cassette 6 in the actual cassette stock section 32 runs out, the actuator 29 constituting the proximity switch overlaps the stator 42, as described above, and a tape end signal is issued. When this signal is issued, the air cylinder 41 is actuated to retract the pin 40 that positions the lowest cassette 6, making the empty cassette 6b movable. Next, the air cylinder 34 pushes the empty cassette 6b and moves it laterally along the rails 49, 49, thereby feeding it from the real cassette stock section 32 into the empty cassette 33. Thereafter, in the real cassette stock section 32, a new real cassette 6a is supplied as described above.

The empty cassette stock section stores the cassettes fed one after another as described above in a stacked manner. That is, the empty cassette that has been sent in is lifted up by a lift, pushed under the other empty cassettes that are already held in the air by the supporting tools, and stored together with these empty cassettes while being held in the hollow by the supporting tools. That is, the new empty cassette lifted by the lift is placed at the corner 5 of the support 50.
While pushing up 4, pass through the support position upwards,
During this time, the empty cassette is piled up under other empty cassettes, and when lowered into the lift, it is held in the air by the support 50 together with the other empty cassettes.

In this taping device, after the clamp has grasped the coil, the tape 10 is placed facing the pasting location 35 (see FIG. 3), as shown in FIG. 7a.
The coil 1 is pressed onto the tape 10a, and the coil 1 and the tape 10a are attached as shown in FIG. 7b. As shown in the figure, the actual cassette is arranged so that the tape 10a is in contact with the tape rail 12 and faces the place where it is to be pasted. In the figure, 38 is a jig.

In the cassette according to the present invention, the tape presser holds the leading end of the tape before the tape is used so that the tape does not shift from the tape rail when the actual cassette is fed. Therefore, when the tape of the actual cassette is first attached to the coil, the tip of the tape protrudes from the side of the coil.
Also, with this taping device, when cutting off the tape part for the first coil and the tape part for the next coil, the tape is not cut off at the end of the next coil, but at a slightly distant position. There is. Therefore, the leading end of the tape still protrudes from the side of the coil. Therefore, in this device, after the tape and coil are attached, a tape presser is used to press the tip of the tape against the coil.

The leading end of the tape is pressed against the coil in the following manner. The taping device is provided with drive means 43 for pushing the slide plate of the cassette, as shown in FIG. That is, a hole is made in the tape 56 of the device, and a vertical plate 57 is fixed to the wall of this hole. Gears 58 and 59 that mesh with each other are arranged on the top and bottom of this vertical plate 57. A lever 60 is fixed to the upper gear 58, and the lower gear 59 is rotated forward and backward by an air cylinder 61. There is. When the lower gear 59 rotates forward and backward, the lever 60 becomes horizontal or vertical, and the tape presser 13 of the cassette 6 is moved back and forth. That is, when the lever 60 changes from horizontal to vertical, the lever 6
0 passes through the hole 21 at the bottom of the cassette and pushes the slide plate 16 forward, causing the tape presser 13 to come forward. Conversely, when the lever 60 changes from vertical to horizontal, the coil spring 20 (see FIG. 2) attached to the slide plate 16 moves the slide plate 16 backward, thereby retracting the tape presser 13.

When the tape presser 13 comes forward, as shown in FIG. 9, the tip of the tape presser 13 presses the tip of the tape 10a against the side surface of the coil 1 to adhere it. When the holder 14 holds the tip of the tape 10a, when the tape presser 13 sticks out, the tip of the tape 10a is separated from the tape presser 13 and the holder 14 and is stuck to the side of the coil 1. .

In this taping device, after the tip of the tape is pressed against the coil as described above, the jig inserted into the coil moves laterally, and the tape is wound from the application location 35 as shown in FIG. Transfer coil 1 to location 62. After that, the tape is cut by the cutter 39, and then the jig 38
rotates and the tape is wound around the coil 1.
After the tape has been wound, the jig 38 is removed from this coil and returned to the application location 35 to enter the next coil. When the jig 38 transfers the next coil 1 to the tape winding place 62 again, a push rod attached to the jig 38 (not shown in the figure) transfers the next coil 1 to the tape winding place 62 (not shown). The finished coil) is pushed out to the discharge location 63. The coil 1 pushed out to the discharge location 63 is discharged out of the device by the crank mechanism 64. In the figure, 65 is a guide rail, 66 is a guide roll, and 67 is a tape correction roll. When cutting is performed between the tape part of the previous coil and the tape part of the next coil, these are used to cut the tape part of the previous coil. Pinch the rear part of the tape part. Therefore, when the tape is wound around the previous coil, the tape is prevented from falling off the guide rail 65 and meandering. Reference numeral 68 denotes a tape pressing roll, which is biased by a cylinder 69 to press the side surface of the coil 1 that has been transferred to the winding location 62. While the tape pressing roll 68 presses the tape against the coil 1, the jig 38 rotates and the tape is wound around the coil 1. The taping apparatus uses the cassette according to the present invention and performs taping in this manner.

In the embodiment of the cassette for a taping device according to the present invention, the tape reel is positioned by a shaft installed in the frame, but the positioning means is not limited to this. for example,
It may be a shaft hole provided in the frame. In this case, use a tape reel with a shaft and insert it into the shaft hole of the frame. The tape end holder is not necessarily installed on the tape holder, but may be installed separately. Even in this case, it is still necessary to ensure that the tape is released from the holder when the tape presser presses the tape against the object to be taped. When the holder and the tape presser are installed separately, the tape presser is not necessarily installed in the cassette, but may be provided in the taping device. The retainer is not limited to a leaf spring. For example, it may be something like a clothespin, as long as it can hold the tape. However, it goes without saying that the tape presser must be able to easily remove the tape when it presses the tape against the object to be taped.

The cassette for a taping device according to the present invention is constructed as described above, and includes a frame,
It is equipped with a tape reel positioning means, a tape reel, a holder, a tape presser, and a tape end detection means, and is linked to the operation of the taping device, so tape can be automatically replenished and taping can be done without human intervention.
