[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a roll towel from a roll of sheet material.

[0002]

2. Description of the Related Art For example, in a roll towel manufacturing apparatus disclosed in Japanese Utility Model Publication No. 5-33320, a sheet material (nonwoven fabric) fed from a roll is cut by a cutter. However, the cutter becomes dull according to the number of uses,
Must be replaced frequently. Further, if the mounting position of the cutter is shifted or tilted, a cutting failure occurs, so that the adjustment must be made frequently. Therefore, maintenance is very troublesome in the above device. further,
With the built-in cutter inside, there is a danger of injury when inspecting inside.

[0003] In view of the above-mentioned conventional problems, an object of the present invention is to provide an apparatus for manufacturing a roll towel that can be used safely and reliably without maintenance for a long period of time.

SUMMARY OF THE INVENTION The present invention is directed to a sheet supply unit for feeding a sheet material for toweling from a wound roll, and a water supply unit for containing moisture in the sheet material sent from the sheet material supply unit. In a roll towel manufacturing apparatus comprising: a winding mechanism that draws in a sheet material containing moisture, winds the sheet material, and discharges the sheet material; and a control device that controls the operation of each part. The perforated cutting line processing is performed, and after the sheet material is drawn into the winding mechanism portion, the control device controls the feeding speed Vout of the sheet material supply portion and the drawing speed of the winding mechanism portion. By setting the relationship with Vin to 0 ≦ Vout <Vin,
The sheet material containing water is cut at a cutting line by applying a predetermined tension to the sheet material (claim 1). In the roll towel manufacturing apparatus configured as described above, the relationship between the feeding speed Vout of the sheet material supply unit and the retraction speed Vin of the winding mechanism unit is set to 0 ≦ Vout <Vin, so that a predetermined value is applied to the sheet material. Tension is applied. At this time,
Since the sheet material contains moisture, it is easier to cut than a dry state. Therefore, the sheet material is cut along the cutting line.

In the above-mentioned apparatus for manufacturing towels (Claim 1), the winding mechanism comprises a winding roller driven to rotate, a driven roller, and a conveyor belt stretched over the winding roller and the driven roller. And a fixed belt provided on the outer peripheral side of the conveyor belt and drawing the sheet material between the conveyor belt and the cutting device. After the sheet material runs on the outer periphery of the winding roller, the cutting is performed. (Claim 2). In this case, the winding end of the sheet material rides on the outer periphery of the winding roller, is stably held between the conveyor belt and the fixed belt, and supports the tension.

[0006] In the above-mentioned roll towel manufacturing apparatus (Claim 1), the cutting line processing is performed in the width of 50 to 9 of the sheet material.
9.9% may be cut in advance (claim 3). In this case, since the remaining portion to be cut is 0.1% to 50%, cutting is easy.

[0007] In the above-mentioned roll towel manufacturing apparatus (Claim 1), the sheet material supply section includes a supply roller that is driven to rotate, a driven roller that moves in accordance with the supply roller,
A supply guide for guiding the sheet material may be provided (claim 4). In this case, the sheet material is fed by the supply roller and the driven roller, and the feeding direction is set to a predetermined direction by the supply guide.

Further, in the above-mentioned roll towel manufacturing apparatus (Claim 4), a portion of the supply roller which contacts the sheet material may be discontinuously formed in the axial direction (Claim 5). In this case, an increase in contact resistance between the supply roller and the sheet material can be prevented.

Works. The control device 15 (FIG. 10) that has received the operation signal of the limit switch 510 operates the motor 401 (FIG. 2, FIG. 1).
0) is stopped. Accordingly, the rotation of the supply roller 404 stops. Therefore, the sheet material 2a whose feeding operation has been stopped is pulled by the winding roller 503, and the tension increases. As a result, as shown in FIG. 14, the sheet material 2a is cut at the cutting line L. In this case, the sheet material 2
When a is wet, cutting becomes easier than in a dry state. At the time of cutting, the wound end of the sheet material 2a rides on the winding roller 503 and is held between the conveyor belt 506 and the fixed belt 507, so that the tension can be supported.

Thereafter, the cut sheet material 2a is
It is further conveyed by the conveyor belt 506 while being wound, and finally discharged from the discharge port A (see FIG. 15).
The control device 15 (FIG. 10) operates the motor 501 (FIGS. 5 and 10) after a predetermined time from the operation of the limit switch 510.
Is stopped, and the rotation of the winding roller 503 stops.

In the above embodiment, the sheet material 2a is pulled and cut by stopping the supply roller 404 and rotating only the winding roller 503.
Slow the rotation of the supply roller 404 or
The sheet material 2a can be similarly cut by increasing the rotation of the sheet 03. In short, the relationship between the feeding speed Vout of the sheet material supply unit 4 and the drawing speed Vin of the winding mechanism unit 5 may be set to 0 ≦ Vout <Vin.

According to the apparatus for manufacturing towels according to the first aspect, the relationship between the feeding speed Vout of the sheet material supply unit and the retraction speed Vin of the winding mechanism unit is set to 0 ≦ Vout <Vin, so that cutting is performed including moisture. A predetermined tension is applied to the sheet material that has become easy, and the sheet material can be cut along a cutting line without using a cutter. Therefore, the roll towel manufacturing apparatus can be used safely and reliably without maintenance for a long time.

According to the second aspect of the present invention, the wound end of the sheet material is stably held between the conveyor belt and the fixed belt by riding on the outer periphery of the winding roller, thereby supporting the tension. Therefore, the cutting can be surely performed.
