Abstract

A sonic label welding device for welding multiple labels together using ultrasonic welding is disclosed. The sonic label welding device comprises a digital controls main menu screen which includes touch screen buttons that are utilized to go to specific screens to program the device to perform in a certain manner. For example, a user can press the cut to length button if wanting to cut a label to a specific length, or the label weld count button to specify the number of labels being sonically welded. Further, the sonic label welding device comprises a head for allowing multiple labels to be assembled under pressure and an anvil for directing the high frequency vibrations. A method of manufacturing a multi-layer care label is also disclosed.

First claim

What is claimed is:

1. A sonic label welding device for welding multiple labels together using ultrasonic welding, comprising:
a digital controls main menu screen comprising touch screen buttons that are utilized to go to specific screens and the touch screen buttons include one or more of the following: a registration button, a cut to length button, a printer screen button, and a timer button;
an anvil;
a head;
a converter;
a sonic horn; and
a power supply; and
wherein the power supply delivers an electrical signal, the converter converts the electrical signal into a mechanical vibration, and the sonic horn applies the high frequency, mechanical vibration to the multiple labels to be welded together.

2. The sonic label welding device of claim 1 , wherein the main menu screen further comprises one or more of the following: a start cycle button, a stop cycle button, a move registration number button, and an escape button.

3. The sonic label welding device of claim 1 , wherein the head is comprised of a knurled surface.

4. The sonic label welding device of claim 1 , wherein the device further comprises an air cylinder and a solenoid valve for controlling the air cylinder.

5. The sonic label welding device of claim 1 , wherein the strength of the welding is such that a top label or a bottom label can be torn off of the multiple labels welded together without destroying a remaining set of labels in said multiple labels welded together.

6. A sonic label welding device for welding multiple labels together using ultrasonic welding, comprising:
a digital controls main menu screen comprising touch screen buttons that are utilized to go to specific screens;
an anvil;
a head;
a converter;
a sonic horn;
at least one patterned plate that comprises variable data;
a power supply;
a knife; and

the power supply delivers an electrical signal, the converter converts the electrical signal into a mechanical vibration, and the sonic horn applies the high frequency, mechanical vibration to the multiple labels to be welded together.

7. The sonic label welding device of claim 1 , further comprising a knife.

8. The sonic label welding device of claim 1 , wherein one of the screens is a registration screen.

9. The sonic label welding device of claim 8 , wherein the registration screen has multiple controls for using a registration mark on a product.

10. The sonic label welding device of claim 1 , further comprising a welding station with a welding cylinder, a welding bar, a hopper, a gate and a gate cylinder.

11. The sonic label welding device of claim 1 , wherein the sonic horn requires an input voltage of between 207 to 253 volts.

12. The sonic label welding device of claim 1 , wherein the sonic horn outputs 36 kHz and approximately between 500 to 1200 Watts.

13. The sonic label welding device of claim 6 , wherein the knife is a cutting knife.

14. The sonic label welding device of claim 6 , wherein the knife is a cold knife.

15. The sonic label welding device of claim 6 , further comprising an outfeed conveyor and hopper.

16. The sonic label welding device of claim 6 , further comprising at least one sensor.
