Description

[Detailed description of the invention] The present invention relates to an automatic tape pasting device for pasting tape such as FRP prepreg tape onto the surface of an object to be pasted such as a mold. This invention relates to an improvement of a pressing roll part for running and pasting while pressing.

As shown in FIG. 1, in this type of device, a tape 1 pulled out from a tape reel 3 via a guide roll 4 by pull-out rolls 5, 5 and a protective paper 2 pasted on one side of the tape is cut into a tape cutting section 6. , the pressing roll 9 via the preheating section 7 and the guide roll 8
The pressing roll 9 presses the tape 1 onto the surface of the object to be applied 10 through the protective paper 2, and the X, Y, Z axes shown in FIG. a rotation axis a centered on the axis;
Pressing roll 9 by simultaneous NC control of 6 axes b, c,
By running the tape 1 along the surface of the object 10 to be affixed, the tape 1 is affixed to the surface of the object 10 to be affixed without any gaps, and then the tape 1 is affixed multiple times by changing the affixing direction to form a board with a desired shape. I'm starting to do that.

The protective paper 2 is wound onto a take-up tape reel 11, and only the tape 1 is cut by the tape cutting section 6 in accordance with the length of pasting each time.
Since tapes of various widths are normally used in this device depending on the size and surface shape of the object 10 to be applied, the pressing roll 9 is provided with a width matching the widest tape 1. However, in this device, when the surface of the object 10 to be pasted is curved or inclined in the width direction, even if the pressing roll 9 is made elastic, the pressing force cannot be applied uniformly over the entire width. This results in areas where it is not possible to securely adhere the parts.

The present invention was devised in view of the above-mentioned points, and by attaching the pressing roll in a removable manner and changing the pressing roll to one with a width equal to the width of the tape, it is possible to find the most suitable one that matches the tape width. To provide an automatic tape pasting device capable of pasting tape in a proper state.

Figures 2 to 4 below show an embodiment of the present invention.
The diagram will be explained. In FIG. 2, 1 is a tape, 8 is a guide roll, and 9 is a pressing roll.
Note that the protective paper 2 is omitted in this figure. The pressing roll 9 is attached to the stay 1 via a bearing (not shown).
It is rotatably attached to 2. A shaft 13 is provided protruding from the upper center of the stay 12, and a shank 14 is attached to the shaft 13. Shyank 14 is
It is designed to be detachably attached to a socket 16 provided on the movable plate 15. Note that 17 is a pin for securely fixing the shank 14 to the socket 16, and 18 is a hole for removing the shank 14. The movable plate 15 is connected via two cylinders 19 to a cylinder mounting plate 20 attached to a main body (not shown) that supports the guide roll 8 and the like of this device. These cylinders 19, 19 are provided parallel to the shaft 13 and the shank 14, and apply a downward pressing force to the pressing roll 9 parallel to the shaft 13 and in FIGS. 2 to 4. There is.

Next, the operation of this device will be explained. For example, as shown in FIG. 3, when the surface of the object 10 is concave in the width direction of the pressing roll 9, the pressing force at both ends becomes strong, but the pressing force at the center becomes weak.
Air between the tape 1 and the surface of the object to be applied 10 cannot be expelled, and air 21 may enter this area. This can be improved by providing elasticity to the pressing roll 9, but there is a limit to this. Therefore, the width of the tape 1 is reduced by the radius of curvature of the unevenness, the pin 17 is removed, a shank (not shown) is inserted into the shank hole 18, the shank 14 is removed from the socket 16, and the width is equal to the width of the tape 1. By changing to the pressing roll 9, even if the radius of curvature is small, the air between the object 10 and the tape 1 can be expelled and the tape 1 can be reliably affixed. By using a pressing roll 9 of a corresponding width, more efficient pasting becomes possible.

As described above, according to the present invention, it is possible to use tapes of various widths and to apply the tape most suitable for the width of the tape, thereby making it possible to perform more reliable and efficient application.
