Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an automatic tape mounting device for mounting magnetic tape, paper tape, adhesive tape, or the like.

Conventionally, for example, a horizontal computer magnetic tape device using magnetic tape has a supply reel formed by winding the magnetic tape on a device base, and a winding unit (for example, a winding hub) that winds the magnetic tape. It is rotatably provided across the tape running path, and has guide rollers, magnetic heads, etc. placed at predetermined positions along the tape running path. After the tape running path is sealed by placing a cover over these functional components, air is blown from the supply reel side to guide the leading edge of the magnetic tape into the tape running path.
The configuration is such that air is taken in on the take-up reel side and the leading end of the magnetic tape is automatically attached to the take-up section.

However, in the case of a device having the above configuration, there are the following problems.

One of them is that the tape running path is completely sealed by the cover, so the wind sent out from the two ventilation ports wraps around inside the tape running path, creating a eddy flow. The leading edge of the magnetic tape unwound from the supply reel may stop running midway through the supply, twist several times before reaching the take-up section, or the leading edge of the magnetic tape may run in a spiral shape. However, there is a problem in that it is difficult to attach it to the winding section.

Next, the leading edge of the magnetic tape unwound from the supply reel is introduced into the tape running path while being pressed by the air from the two air outlets, but if the air volume of the two air outlets is even slightly unbalanced, There is a problem in that the leading edge of the magnetic tape gets stuck on one wall of the tape running path, making it impossible to run.
For this reason, there is a problem in that it is very difficult to adjust the timing of starting air blowing and the amount of air blowing by the two air blowing ports. Similar problems also exist with paper tapes and adhesive tapes.

The present invention has been made in view of the above-mentioned circumstances, and is an automatic tape system that eliminates twisting of the tape due to wind and sticking to the wall of the tape running path, and stably introduces the tape into the tape running path and runs it on the tape running path. The purpose is to provide a mounting device.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3. Note that FIG. 1 shows the arrangement of functional parts in the upper part of the device, FIG. 2 shows the main parts of the present invention, and FIG. 3 shows the internal structure of the winding section. In FIG. 1, reference numeral 10 denotes a device base such as a horizontally placed computer magnetic tape device, and a supply reel 12 for a magnetic tape 11 is rotatably provided on the front side of the upper part of the base 10. A winding section 13 for winding up the magnetic tape 11 is rotatably provided on the rear right side of the upper part of the magnetic tape 10.
On the base 10 on which the supply reel 12 and the winding section 13 are located, there are recesses 10a and 10b having spaces that take into consideration the winding width of the magnetic tape 11 wound around the supply reel 12 and the winding section 13. In particular, the concave portion 10a on the supply reel 12 side is formed to be wider toward the front side in consideration of the space for arranging the two ventilation ports 14 and 15. Furthermore, a recess 10a on the supply reel 12 side and a recess 10 on the winding part 13 side
b through a curved tape running path 16 having approximately the same depth. The two air blowing ports 14 and 15 are arranged in the recess 10a so as to blow air in the directions of arrows A and B in the figure. In the figure, 1
7 is a tape path sensor for detecting the passage of the magnetic tape 11; 18 is a tension roller; 19 and 20 are guide rollers; 21 is a tape cleaner; and 22 is a magnetic head.

After arranging each functional component as described above, the top of the base 10 is covered with a cover 23 as shown in FIG. The feature of this device is that the cover 23 itself is provided with a groove 24 through which the air sent out from the air outlets 14 and 15 flows out through the tape running path 16 to the outside of the device. . It is desirable that this groove 24 be provided along the approximate center of the tape running path 16 if possible, and in a positional relationship such that it can be easily attached to the winding section 13 on the rear end side. do.

As shown in FIG. 3, the winding unit 13 side includes a winding unit (for example, a winding hub) 13 connected to the rotating shaft of a motor 131, a tape fall prevention plate 132,
The reel fixing pin 133 is configured to rotate integrally with the reel fixing pin 133. Reference numeral 134 designates a speed detector which also serves as a tape holder, and reference numeral 135 designates a member provided with a hole 135a for sucking air in the direction of the arrow shown in the figure. Note that an air intake port (not shown) is provided inside the winding section 13 side. The air intake state on the side of the winding section 13 is shown in the direction of the arrow D in the figure.

Next, the operation of the device configured as above will be explained. To feed out the magnetic tape 11, the supply reel 12 is rotated in the tape winding direction (in the direction of the arrow H in the figure), and air is blown from the two air outlets 14 and 15 in the directions A and B in the figure. Here, when the leading end of the magnetic tape 11 wound around the reel 12 passes through the wind blowing part of the air outlet 15 due to the rotation of the supply reel 12, the leading end side of the magnetic tape 11 passes through the air outlet 15. The tape is bent by the wind and sent out to the tape running path 16 side. When the leading edge of the tape approaches the entrance of the tape running path 16, the magnetic tape 11 is exposed to the wind from the two air outlets 14 and 15. As shown in FIGS. 2A and 2B, a flow path is created to sandwich the magnetic tape 11, and the magnetic tape 11 is discharged from the groove 24 of the cover 23 to the outside of the apparatus.
As a result, the magnetic tape 11 is erected on the tape running path 16 directly below the groove 24 with one side wall as the bottom due to the above-mentioned wind flow, and in this state, the magnetic tape 11 is placed along the tape running path 16 along the shape of the groove 24. running on top. Therefore, the wind from the two ventilation ports 14 and 15 enters the tape running path 16 at once, but
Since the air flows outward from the groove 24 of the cover 23 located approximately at the center of the tape, the air sent out from the air outlet does not swirl inside the tape running path 16 as in conventional devices. Therefore, the magnetic tape 11 will not be twisted multiple times or spirally, making it difficult to run. Further, the leading end of the magnetic tape 11 runs stably without biting into one wall of the tape running path 16.
When the leading end of the magnetic tape 11 approaches the rear end of the groove 24, the leading end of the tape is easily attached to the winding part 13 under the influence of air intake from the winding part.

Note that when the passage of the magnetic tape 11 is detected by the tape path sensor 17, the supply reel 12 starts rotating in the direction of the arrow shown in the figure in response to the detection signal, entering a so-called normal tape supply state, and at this time, the winding section 13 It also rotates.

Note that the present invention is not limited to the above embodiments. In the above embodiment, the cover 23 is provided with the groove 24, but as shown in FIGS. 4A and 4B, for example, the cover 23 has a plurality of holes 24a along the tape running path 16.
Alternatively, a plurality of holes 2 may be provided in the base 11 corresponding to the bottom of the tape running path 16 as shown in FIG.
4b... may also be provided. Further, although the above embodiments have been described with respect to a horizontal type device, a vertical type device may also be used. However, in this case, it is necessary to arrange the tape supply side member at the top and the tape winding section side member at the bottom. Further, the present invention is not limited to magnetic tape, and can be similarly applied to paper tape and adhesive tape. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.

As described in detail above, according to the present invention, the cover itself is provided with an air outlet such as a groove or a hole along the tape running path, so that the magnetic tape is moved along the wind flow directly below the air outlet. The tape can be reliably installed and run on the tape running path. Therefore, the tape can be introduced into the tape running path without being twisted by the wind or sticking to the wall of the tape running path, and the tape can be run stably on the tape running path. Further, since stable running of the tape is ensured, it is possible to provide an automatic tape loading device that can reliably load the tape onto the winding section.
