The inner surface of the magnetic tape 1 is adhered to the inner magnetic tape 1 (the second outer magnetic tape 1) of the outermost magnetic tape 1 by a splice tape 43 as an adhesive tape, and is subjected to a peripheral end treatment. The hub 2 of the pancake 3 is removably mounted on a delivery shaft 4 as a coil shaft. The delivery shaft 4 is driven by a shaft drive motor 9 (FIG. 5). Further, when the pancake 3 is mounted on the delivery shaft 4, the tape leading end device 10 as the leading end device of the belt-like material grips and pulls the leading end of the magnetic tape 1 hanging from the pancake 3. .

Reference numeral 5 in FIG. 2 denotes a tape cutting and joining device. The tape cutting and joining device 5 is configured such that when the tape leading-out device 10 grips the leading end of the magnetic tape 4 of the pancake 3 attached to the sending shaft 4 and pulls it out, and conveys it onto the tape suction block 6, The tape 1 and the other magnetic tape 1 are attracted to the tape suction block 6, and these tapes are cut by a cutter (not shown).
These two magnetic tapes 1 are joined together. Thereby, the tip of the magnetic tape 1 of the pancake 3 attached to the delivery shaft 4 and the other magnetic tape 1 are connected.
Reference numeral 8 in FIG. 2 indicates a guide roller.

The tape leading-out device 10 includes a feed shaft 4, a suction unit 11, a moving block 12, a moving rail 13, a driving belt 14, a vacuum generator (for example, a vacuum pump) 15 shown in FIG. It has a control panel 16 as a device. The above moving block 1
2. The moving rail 13 and the drive belt 14, and the later-described advance / retreat drive motor 23 constitute an advance / retreat drive unit.

The delivery shaft 4 is, as described above, a pancake 3

The driving belt 1 is attached to the holding bracket 18.
The driving belt 14 is wound around a driving pulley 21 and a driven pulley 22. The drive pulley 21 is connected to a forward / backward drive motor 23 that can rotate forward and backward. Accordingly, the drive belt 14 moves on the moving rail 13 by the forward / reverse rotation of the advance / retreat drive motor 23, and as a result, the suction unit 11 is configured to be able to advance and retreat toward the feed shaft 4 in the direction of arrow A. Here, reference numeral 24 in FIG. 2 is a long window 24 opened in the substrate 17.

The suction unit 11 has a unit housing 25 as shown in FIG. In the unit housing 25, two suction holes 26A and 26B are drilled in parallel, and a suction hole 26C communicating the suction holes 26A and 26B is also drilled. The suction hole 26C is formed orthogonal to the axis of the suction holes 26A and 26B.

A suction pipe 27 is fitted in the suction hole 26A, and an air tube 28 is fitted in the suction hole 26B. In the air tube 28, an air filter 29, a solenoid valve 30, and the vacuum generator 15 are sequentially arranged. Vacuum generator 1
By the ON operation of 5 and the opening operation of the electromagnetic valve 30, the inside of the suction holes 26A, 26B and 26C of the unit housing 25 is set to a negative pressure. Due to this negative pressure, the tip of the magnetic tape 1 hanging from the pancake 3 is sucked into the suction holes 26A, 26C and 26B via the suction pipe 27.

A rubber cushion 31 (tape holding member) as a locking member is accommodated in the suction hole 26A. The rubber cushion 31 has an outer diameter substantially equal to the inner diameter of the suction hole 26A, and is attached to the piston rod 33 of the air cylinder device 32. Air cylinder device 3
The second cylinder 34 is fitted and fixed to the unit housing 25. The movement of the piston 35 of the air cylinder device 32 causes the rubber cushion 31 to reciprocate in the axial direction (arrow B) of the suction hole 26A via the piston rod 33. The rubber cushion 31 is set at the position indicated by the two-dot chain line by the forward movement of the rubber cushion 31, and the rubber cushion 31 transfers the magnetic tape 1 from the suction hole 26A to the suction hole 26C with the wall surface 36 of the suction hole 26A. Sandwich between.

In the unit housing 25, a pair of transmission type optical sensors 37 as a tape detection sensor are provided. The pair of optical sensors 37 are arranged to face each other in the axial direction of the suction hole 26C. These optical sensors 37 detect that the magnetic tape 1 sucked into the suction hole 26A reaches at least the suction hole 26C. This tape position detection signal b is output to the control panel 16 as shown in FIG.

On the other hand, a pipe head 38 having a flange 38A is loosely fitted to the tip of the suction pipe 27 shown in FIG. As shown in FIGS. 3A and 4, the pipe head 38 is provided to be slightly movable in the axial direction of the suction pipe 27 by being guided by a guide pin 39. The tension detection roller 40 faces the tip of the pipe head 38 and
It is set up.

A sensor arm 41 is fixed to the unit housing 25 shown in FIG. 1, and a head touch sensor 42 is attached to a tip of the sensor arm 41. The head touch sensor 42 detects the position of the pipe head 38 when the suction unit 11 advances in the direction of arrow A toward the sending shaft 4 and the tension detecting roller 40 contacts the pancake 3 and the pipe head 38 is slightly retracted. By contacting the flange 38A, it is detected that the suction unit 11 has advanced to a predetermined position. The suction unit position detection signal a from the head touch sensor 42 is output to the control panel 16 as shown in FIG.

The tension detecting roller 40 shown in FIG. 4 is always in contact with the front or back surface of the magnetic tape 1 sucked from the pancake 3 into the suction holes 26A, 26B and 26C of the suction unit 11 and into the suction pipe 27.

2 from the optical sensor 37
, And a tension signal c from the tension detection roller 40 are input. The control panel 16 outputs respective operation signals to the shaft drive motor 9, the forward / backward drive motor 23, the vacuum generator 15, the solenoid valve 30, and the air cylinder device 32.

In particular, when the suction unit position detection signal a is input from the head touch sensor 42, the control panel 16 stops the forward / reverse drive motor 23 from rotating forward and stops the suction unit 11 from moving forward. Further, when the tape position detection signal b is input from the optical sensor 37, the control panel 16 operates the air cylinder device 32 to operate the rubber cushion 31.
To move the magnetic tape 1 between the rubber cushion 31 and the wall surface 36 of the suction hole 26A. Further, when the control panel 16 receives the tension signal c from the tension detection roller 40 and determines that the tension acting on the magnetic tape 1 is excessive, the control panel 16 controls the shaft drive motor 9 to cause the sending shaft 4 to move the magnetic tape 1 to the magnetic tape. By rotating the magnetic tape 1 in the rewinding direction Q to increase the tape sending speed, the tension of the magnetic tape 1 is controlled. Further, the control panel 16 suctions the outermost magnetic tape 1 of the pancake 3 by the suction unit 11 and holds the magnetic tape 1 by the rubber cushion 31, and then controls the shaft drive motor 9 to
Rotate the sending shaft 4 in the rewinding direction Q of the magnetic tape 1;

Then, the pancake 3 is rotated in the winding direction P of the magnetic tape 1. At the same time, the control panel 16 rotates the forward / backward drive motor 23 forward to move the suction unit 11 along the moving rail 13 toward the delivery shaft 4. During this forward movement, the control panel 1
6 turns ON the vacuum generator 15 and opens the solenoid valve 30 to set the inside of the suction holes 26A, 26B and 26C of the suction unit 11 to a negative pressure.

As shown in FIGS. 6B and 8B,
The tension detecting roller 40 of the suction unit 11 is
When the pipe head 38 retreats and the head touch sensor 42 abuts on the flange 38A of the pipe head 38, the control panel 16 moves forward and backward based on the unit position detection signal a from the head touch sensor 42. Motor 2
3 is stopped, and the suction unit 11 is stopped. Immediately thereafter, as shown in FIGS. 6C and 8C, the control panel 1
In step 6, the advancing / retreating drive motor 23 is slightly reversed to slightly retract the suction unit 11 and stop.

The control panel 16 determines that the tension of the magnetic tape 1 detected by the tension detecting roller 40 is equal to or less than a predetermined value (FIG. 8E).
The tape drive speed of the delivery shaft 4 is not increased by the shaft drive motor 9, but when the tension of the magnetic tape 1 is excessive, as shown in FIG. Then, the tape sending speed of the sending shaft 4 (the rewinding direction Q of the magnetic tape 1) is increased to control the tension applied to the magnetic tape 1.

Thus, the suction unit 11 is retracted to a position below the tape cutting and joining device 5 shown in FIG. At this position, the tape tip of the pancake 3 held by the suction unit 11 is cut by a cutter (not shown) of the tape cutting and joining device 5.
