Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape running device, particularly an NC tape running device.
It relates to a traveling device for information exchange tape such as control tape used in machine tools.

Control tapes that give commands to the control section of NC machine tools include magnetic tapes, perforated paper tapes, and the like, and these tapes are usually wound on reels. The tape roll wound on the reel is loaded on the supply side, the tape is pulled out from the outside of the tape roll, and the tape is supplied to the take-up reel via the control unit and wound, so the same command can be given again. It was necessary to rewind the tape that had been wound.

The present invention aims to eliminate such drawbacks of the prior art.

The present invention rotates the tape roll from the inside of the tape roll loaded in a supply device and supplies the tape to an information exchange device. The above-mentioned object is achieved by providing a tape running device that winds up a tape by temporarily fixing the end portion to a winding shaft, and then removes the tape after winding is completed.

The present invention will be explained in detail based on the drawings.

FIG. 1 is a schematic diagram showing the principle of a tape running device according to the present invention, and FIG. 2 is a perspective view of a roll used in the tape running device of FIG. 1.

The principle of the tape running device according to the present invention will be explained.

Load the tape roll 4 wound into an annular shape into the supply device 1, and while rotating the tape roll 4, feed the tape roll 4.
The inner starting end 6 is pulled out, and the tape 5 is fed to the winding device 2 via the information exchange device 3. tape 5
Since the tape is twisted each time it is pulled out from the inside of the tape roll 4, the tape roll 4 is rotated at a predetermined speed depending on the speed at which the tape 5 is pulled out.
At that time, if a tape with relatively high rigidity is used relative to the weight of the tape roll 4, the tape roll 4 can be easily pulled out without using any external force.
It is possible to rotate. If the tape 5 has relatively low rigidity compared to the weight of the tape roll 4,
When using an external force, the tape roll 4 may be rotated at a predetermined speed to prevent the tape 5 from twisting.

By winding the tape 5 supplied to the winding device 2 so that the starting end 6 is on the inside, it becomes a tape roll in the same state as the tape roll 4 before tape supply as shown in FIG. 2, and can be used again. There is no need to rewind the tape.

Next, a specific configuration of the tape running device according to the present invention will be explained.

As shown in FIG. 3, in the supply device 1, a shaft 10 is vertically disposed on a base plate 9 of a box-shaped frame 8, and a roller 12 is rotatably supported on the shaft 10 via a bearing 11. The roller 12 has a length that is more than twice the width of the tape, and has a flange 1 at the end for guiding the tape.
3 is formed. The frame body 8 is provided with a partition plate 15 having an opening 14 through which a roller 12 passes through the substrate 9 at a predetermined interval. A roller 18 is supported via a bearing 17, and a slit 19 is formed in the upper surface of the frame 8 in parallel with the roller 12.

As shown in FIG. 4, the winding device 2 includes a winding drum 2 mounted on a box-shaped frame 20 having a slit 22 formed on the top surface.
1 is rotatably supported, and the winding drum 21 is connected to a drive source such as a motor via a drive shaft (not shown). As the cross section of the winding drum 21 is shown in FIG. be done. As shown in FIG. 6, by pressing the key 24 in the axial direction against the bias of the spring 25, a gap 26 is created between the key 24 and the groove 23, and the starting end of the tape 5 is formed in the gap 26. Hold 6.

The information exchange device 3 may be of any type as long as it satisfies the format of exchanging information with the tape 5 supplied from the supply device 1 and feeding the tape 5 to the winding device 2. It can be selected as appropriate depending on the type of tape 5.

The operation of the tape running device will be explained below.

A tape roll 4 as shown in FIG.
The starting end 6 of the tape roll 4 is pulled out from the opening 14 and fed to the information exchange device 3 through the slit 19 using the flange 13 as a guide. Next, the tape 5 fed from the information exchange device 3 is passed through the slit 2 of the winding device 2.
2 and pull the starting end 6 into the key 2 of the winding drum 21.
4 and the groove 23 to complete the traveling preparation.

The tape 5 starts running when the drive source starts and the winding drum 21
This is done by rotating and winding up the tape 5. The tape 5 runs while exchanging information in the information exchange device 3, and the end 7 of the tape reaches the supply device 1.
After the tape is completely wound up on the winding drum 21, the starting end 6 of the tape is pulled out from the gap 26 by pressing the key 24, and the tape roll 4 is removed from the winding drum 21. The removed tape roll 4 can be used without being rewound by loading it into the supply device as it is.

When the rigidity of the tape 5 is small compared to the weight of the tape roll 4, the substrate 9 of the supply device 1 is made rotatable relative to the frame 8, and the outside of the tape roll 4 is gripped by the rollers 18. Design and tape 5
The rotational speed of the tape roll 4 may be set according to the drawing speed of the tape roll 4.

As described above, according to the tape running device according to the present invention, information is exchanged by running the tape, and when the running of the tape ends and the tape is wound, preparations are made to exchange the same information again. is completed, there is no need to rewind the tape, information processing can be done in a short time, and the life of the tape is also extended. Further, since the feeding device of the tape running device of the present invention includes rollers (see reference numerals 12 and 18 in FIG. 3), the tape roll housed in the feeding device rotates smoothly when the tape is running. .
