Description

TECHNICAL FIELD The present invention relates to a tape guide device.

(Prior Art) FIG. 5 is a side view of a tape guide device as a prior example proposed by the present inventor, which is not known. The tape guide device of the prior art example shown in FIG. 1 has a take-up reel 3 having a tape take-up core portion 2 having a first tape guide hole 1. The pair of rollers 4, 4 constitutes a drive mechanism for driving the take-up reel 3 in the direction of arrow b by being rotationally driven in the direction of arrow a by a motor or the like not shown. The tape delivery mechanism 5 includes a tape delivery port 6. The swing lever 7 is swingably supported by a shaft 8 fixed to the tape feeding mechanism 5, and is constantly supported in the direction of arrow c about the shaft 8 by a spring 9 provided on one end side 7a. Being energized. The tape guide 10 has a second tape guide hole 11 penetrating from one end side 10a to the other end side 10b thereof. The tape guide 10 is fixed to the other end side 7b of the swing lever 7 with its one end side 10a being directed to the tape delivery port 6 of the tape delivery mechanism 5, and the other end side 10b is the take-up reel. It is arranged in three directions.

A piston rod 13 of a two-stroke type cylinder 12 as a swing angle adjusting mechanism is fixed in the middle of a tape guide 10. Reference numeral 14 is a tape sent in the direction of arrow d.

 The operation will be described.

First, the tape 14 is attached to the tape winding core 2 of the winding reel 3.
When the tape is wound, the stroke of the piston rod 13 of the cylinder 12 becomes small and the other end 10b of the tape guide 10
Becomes the first state in which the tape is directed to the first tape guide hole 1 of the tape winding core portion 2 of the winding reel 3. Then, in this first state, the tape 14 is delivered from the tape delivery port 6 of the tape delivery mechanism 5, and the tape 14 is attached to the second tape guide hole 11 of the tape guide 10 and the tape winding core portion 2. The tape is sequentially inserted into the first tape guide hole 1.

Then, the leading end 14a of the tape 14 is moved to the first position as it is inserted.
In the second state where it has come out from the tape guide hole 1 of
The stroke of the piston rod 13 of the cylinder 12 increases, and the other end side 10b of the tape guide 10 has a tape winding core 2
Is driven up to the tangential direction of. While the tape 14 is being sent out from the tape outlet 6 in this driving state, the take-up reel 3 is rotated by the rotational driving force of the rollers 4, 4 and the tape 14 is wound around the tape take-up core 2. .

In this way, in the third state in which the tape winding amount around the tape winding core portion 2 reaches the required value, the drive of the cylinder 12 is released, and the biasing action of the spring 9 in the direction of arrow c and the tape winding are performed. The tape is wound on the tape winding core 2 under the action of winding the tape 14 on the winding core 2.

(Problems to be Solved by the Invention) In the tape guide device of the preceding example, the tape 14 is continuously fed from the tape delivery port 6 of the tape delivery mechanism 5 in the third state for winding the tape on the take-up reel 3. When the tape is wound around the core portion 2, due to the biasing action of the spring 9, even if a force in the direction of the arrow e is exerted on the other end side 10b of the tape guide 10, the tape guide 10 retains the tape winding core portion. Since the tape 14 is wound around the tape winding core 2 along the tangential direction of the outer peripheral end 15 of the tape 14 wound around the tape winding core 2, the tape 14 can be provided with unnecessary creases. Instead, the tape is wound around the tape winding core 2.

However, in the case of intermittently sending the tape 14 such as sending and stopping sending, when the sending timing of the tape 14 from the tape sending mechanism 5 is delayed as compared with the timing of stopping the rotation of the take-up reel 3 when the sending is stopped. Can cause the tape 14 to sag.

When the tape 14 is slackened as described above, the tape guide 10 is acted by the spring 9 so that the arrow e as shown in FIG.
It will be lifted in the direction. Then the tape
Since 14 is in an angled state at the end A on the other end side 10b of the tape guide 10, the take-up reel 3 is next.
When the tape 14 is wound by driving the tape, a strong force acts on the tape 14 at the end portion A due to the above-mentioned winding action, and as a result, unnecessary creases are formed on the tape 14.

Such unnecessary folds on the tape 14 leave a big problem that the winding state of the tape 14 on the tape winding core 2 of the winding reel 3 is deteriorated.

The present invention has been made in view of the above problems,
It is an object of the present invention to make it possible to wind a tape in a good condition on a take-up reel even in intermittent feeding of the tape.

(Means for Solving the Problem) In order to achieve such an object, in the tape guide device of the present invention, one end side is arranged in the tape feeding mechanism and the other end side is arranged in the winding reel side, and the one end side is arranged.

(Operation) In the above configuration, the tape delivered from the tape delivery mechanism is taken up by the take-up reel via the tape guide. Then, the swing angle of the tape guide changes according to the tape winding amount of the winding reel. From the detection sensor, a swing angle detection signal corresponding to the swing angle is given to the swing angle adjusting mechanism. Thereby, the swing angle adjusting mechanism adjusts the swing angle of the tape guide.
