Abstract

PURPOSE:To permit welding without causing wrinkles, folded welding and missed welding by an apparatus wherein a plurality of sheets placed one upon another are passed between a rotary roller having a number of pressed bosses over the entire surface and a plurality of ultrasonic vibrators axially arrayed in a special fashion. CONSTITUTION:A plurality of ultrasonic vibrators 3 are axially arrayed along the roll surface of a rotary roll 2 having a number of pressed bosses thereon, and a number of sheet-like materials 4, 5 placed one above another are inserted for transfer between an action surface 3a of the vibrators 3 and the pressed bosses 1 of the roll 2. Then, the sheet-like materials are jointed with to each other by ultrasonic welding. At this time, the plurality of ultrasonic vibrators 3 are aligned with minute gaps 6 therebetween, and the action surface 3a of each vibrator 3 is so formed that sides 3b, 3c opposite to each other with the minute gap make an oblique angle alpha (preferably 70 deg.) relative to the axial direction of the roll 2. By so doing, it becomes possible to prevent wrinkles, loosening and folded welding resulted therefrom.

A device for inserting and transporting overlapping sheets of two or more sheets between a rotating roll and an ultrasonic vibrator and joining the sheet materials in spots by ultrasonic vibration welding is described in the above-mentioned patent publication. However, the device described in this publication has the following drawbacks.

接の作用を受けないから、接合されたシート状物に線状
の溶接欠落があられれる。When multiple ultrasonic transducers are lined up in a row with a little distance between them to avoid resonance, the parts between them are not affected by spot welding, so linear welding can be performed on the joined sheet-like objects. The lack is healed.

できたが、次のような新たな欠点が生じた。In order to prevent such welding missing lines from occurring, in the apparatus described in the above publication, a plurality of ultrasonic transducers are arranged in two rows, shifted in the length direction of the sheet-like object every other time. The entire width can be covered by the action surface of the ultrasonic transducer. Although this method was able to prevent the appearance of missing weld lines, the following new drawbacks occurred.

じるしく損じる。This means that when the stacked sheets reach the first row of ultrasonic transducers and are welded, the parts of the sheets that are not subjected to the welding action between each transducer are wrinkled and overlap. It is. When this overlapped part is subjected to the action of the second row of ultrasonic transducers, this part is welded while being pressed against the edge of the part that has already been welded by the first row of transducers. Folded or seam-like portions appear in the finished sheet-like bonded product, which seriously impairs the appearance of the product.

機構を複雑にする欠点を免れなかった。In order to compensate for this drawback, an invention described in Japanese Patent Publication No. 54-2234 has been proposed. This uses two ultrasonic transducers.
In order to prevent the sheet-like material from being loose between the transducers in the first row due to the arrangement of the transducers in the first row, between each transducer in the first row,
A pressing member that engages with the sheet-like material is provided along the length direction of the row, thereby pressing the sheet-like material to prevent bagging. However, in this method, since the pressure welding member is arranged so as not to come into contact with the vibrator, it is unavoidable that small wrinkles form in the distant part, and the wrinkles are welded into a folded shape by the second row of vibrators. Therefore, damage to the appearance of the sheet-like bonded product could not be completely prevented. In addition, since a pressure contact member is provided, there is a disadvantage that the mechanism of the welding part becomes complicated.

A sonic vibration welding device is provided.

In the present invention, a plurality of ultrasonic transducers (3) are arranged in the axial direction along the roll surface of a rotating roll (2) having embossing protrusions (1) arranged on the roll surface, and two or more ultrasonic transducers (3) are stacked. Combined sheet material +41. +5) is inserted between the working surface (3)a of the ultrasonic vibrator (3) and the embossing protrusion (1) of the roll (2) in a press-contact manner, and the sheet-shaped In a device that joins objects, multiple ultrasonic transducers (3

しく簡単になった。The two sheet materials +4+ and +51 are superimposed and sent to the ultrasonic vibrator (3) and the embossing protrusion (1) of the roll.
When passing between the ultrasonic transducers, the ultrasonic transducers are welded in spots over the entire width. , opposing sides (3) b, f of their action surfaces with a minute interval
31c is configured to form an oblique angle α with respect to the axial direction of the roll (2).
The defects caused by the arrangement of the ultrasonic transducers in two rows in the No. 2 invention, such as wrinkling and bagging of the sheet-like material, and the resulting fold-like welding, do not occur at all. The above-mentioned special public service was adopted in 1973 to eliminate the above-mentioned drawbacks, but the removal of the drawbacks was not yet complete.
The installation of the pressure contact member in the invention of No. 2234 is completely unnecessary in the present invention, and therefore the mechanism of the welding portion is significantly simplified.

均一に伝達することができるので好都合である。Furthermore, in the present invention, although a plurality of ultrasonic transducers are arranged in a row, the intervals between the working surfaces of each transducer are minute, and the sides facing each other with the interval are relative to the axial direction of the roll. Since the working surface is obliquely angled, the working surface can cover substantially the entire width of the moving sheet-like object, and no weld missing lines will occur. In order to prevent missing welds, it is desirable that the bevel angle be as acute as possible, but a bevel angle of about 70° is convenient because vibration can be transmitted almost uniformly to the four corners of the working surface of the ultrasonic vibrator. .
