Recently, a number of automatic wet tissue supply devices have been introduced as an alternative, but most of these devices supply moisture to a tissue bundle consisting of a roll and discharge it as a wet tissue. Tissue is used by being cut along a cutting line, like toilet paper, or by being cut with a cutting blade provided on the discharge side.

Such conventional wet tissue dispensing devices have an image similar to toilet paper, and are not suitable for use in high-end environments such as hotels or offices, and are not easy to cut wet tissues. Not only that, but the cutting blades become damaged or worn out due to long-term use, resulting in an increase in the number of replacement parts.

Further, the arm frame 440 can continue to descend even after the tong member 450 places the tissue (T) on the conveyor member 420. In this case, when the push linear 472 separates from the arcuate surface of the push cam 471, At the same time, the tissue (T) is restored to its original position and the spring force is released, and at the same time, the push roller 473 presses the tissue (T) to seat it on the conveyor member 420.

A first arm switch 474 and a second arm switch 475 are provided at the front and back of the arm frame 440 with the horizontal axis 413 of the tong actuating arm 410 as the center. In this embodiment, the arm switches 474 and 475 are for recognizing the exact position of the tong member 450 due to the lifting and lowering action of the arm frame 440, and the tong member 450 grips the tissue (T) in the tissue supply section 200. A control unit (not shown) recognizes this so that it always operates at the correct position. Preferably, the first arm switch 474 is located at the lower front side of the arm frame 440 with the horizontal axis 413 as the center, and recognizes that the tong member 450 has reached the bottom dead center by contact with the arm frame 440 when it is lowered, and The two-arm switch 475 is located at the lower rear side of the arm frame 440 with the horizontal axis 413 as the center, and recognizes when the tongue member 450 reaches the top dead center by contact with the arm frame 440 as it rises.

According to this embodiment, when the tong member 450 reaches the bottom dead center, the push linear 472 separates from the upper end of the arcuate surface of the push cam 471, and the tong member 450 is located below the conveyor member 420. Further, when the tong member 450 reaches the top dead center, the push linear 472 is located at the lower end of the arcuate surface of the push cam 471, and the tong member 450 is caused to grip the tissue (T) in the tissue supply unit 200 by the control unit. It operates. In this embodiment, although not shown, the first arm switch 474 and the second arm switch 475 can be replaced with a proximity sensor. It is possible to sense when the vehicle reaches the point and when it reaches the top dead center.

The tongue member 450 is hinged to a first tongue portion 451 formed at the tip of the arm frame 440 and the tip of the arm frame 440 that constitutes the first tongue portion, and can be opened and closed with respect to the first tongue portion 451. The upper ends of the first tong part 451 and the second tong part 452 have a number of teeth so that the tissue (T) can be gripped by their interaction. It consists of 451a and 452a.

The tissue detection sensor 445 is exposed at the upper part through a hole on the surface of the arm cover 460, and senses the presence or absence of tissue (T) in the tissue supply section 200 when the tongs member 450 is raised, and detects the presence or absence of tissue (T) in the tissue supply section 200 through a control section (not shown). Apply an alarm signal.

The tong actuating arm 410 having such a configuration moves up alongside the push cam 471 by driving the first motor 411 located on one side of the horizontal shaft 413, but at this time, friction with the arcuate surface of the push cam 471 occurs. The push linear 472 recognizes the rising angle of the tong actuating arm 410 that has risen together with the push cam 471, and then applies a position signal of the teeth 451a, 452a of the tong member 450 located at the tip of the tong actuating arm 410. Become. Then, the second motor 412 is driven to rotate the arm cam 442, and when the wide surface of the arm cam 442 pushes one side of the cam link shaft 443, the second tongue portion 452 overcomes the spring force of the coil spring 444. Then, it spreads out from the first tongue portion 451 centering on the hinge point. At this time, when the presence of tissue in the tissue supply section 200 is confirmed by the tissue detection sensor 445, the second motor 412 continues to drive and rotates the arm cam 442, so that the narrow surface of the arm cam 442 is connected to the cam link shaft 443. When one side is touched, the cam link shaft 443 moves backward, the second tong part 452 is restored, and the teeth 451a of the first tong part 451 and the teeth 452a of the second tong part 452 come into contact again, and the tissue (T) Begins to grasp. If the tissue detection sensor 445 detects that there is no tissue (T) in the tissue supply unit 200, the second motor stops driving, the arm cam 442 stops rotating, and the tissue detection sensor 445 controls the The alarm signal is applied through the section.

When the first tong part 451 and the second tong part 452 of the tong member 450 sandwich the tissue, the first motor 411 is driven in the opposite direction, and the tong actuating arm 410 descends in line with the push cam 471. At this time, the push linear 472 that rubs against the arcuate surface of the push cam 471 recognizes the descending angle of the tong actuating arm 410 that has descended together with the push cam 471, and then detects the descending angle of the tong member 450 located at the tip of the tong actuating arm 410. Position signals 451a and 452a are applied. Then, the second motor 412 is driven again to rotate the arm cam 442, and when the wide surface of the arm cam 442 pushes one side of the cam link shaft 443, the second tongue portion 452 applies the spring force of the coil spring 444. The tissue (T) spreads out from the first tong part 451 around the hinge point and is lowered onto the conveyor member 420 driven by the third motor 431. The tong actuating arm 410 can pull out the tissue in the tissue supply section 200 by repeating such an operation, and the tissue (T) placed on the conveyor member 420 can be pulled out while passing the lower end of the water supply section 300. , moisture is supplied, and the wet tissue is drawn out along the tissue guide 430 located on the discharge side.
