In the embodiment described above, a moving means for the original fabric feeding belt is provided so as to move the original fabric feeding belt of the original fabric feeding device closer to and away from the unraveling device. Even if a moving means is provided in the raw material receiving member of the device,
Alternatively, it goes without saying that the moving means may be provided in both of the devices.

Next, the procedure for spreading the original fabric by the apparatus of the present invention will be described.

First, the original fabric roll 120 is placed on the original fabric receiving member 24 of the unwinding device 4. To do so, as shown in Figure 4,
The original receiving member 24 must be collapsed. Original receiving member 2
The angle of tilting 4 must be such that the original roll 120 does not fall off the original receiving member 24. This angle is determined in advance, and a sensor (not shown) is provided at a position of a predetermined angle.

The turning motor 37 of the original receiving / receiving member 24 is rotated to turn the swing arm 34 via the arm 38 slider 36. Since the swing arm 34 is configured integrally with the V-shaped arm 25, the swing of the swing arm 34 causes the V-shaped arm 25 to swing, and when it corresponds to a sensor not shown, it stops at that position (see FIG. 9). A). This stop position faces the standby position of the original fabric roll, and the original fabric roll is carried into the original fabric receiving member 24 manually or by the carry-in device (B in FIG. 9), and the original fabric receiving member 24 is unwound. When the original fabric roll 120 is placed on the belt 33, the unraveling belt 33 travels in a direction in which the original fabric roll 120 is taken in, and travels until the original fabric roll 120 abuts on the standing unraveling arm 32. To do.

Thereafter, the original receiving member 24 is brought to the upright position by the rotation of the motor 37 in the opposite direction to that described above (C in FIG. 9). Here, the motors 39a and 39b are rotated, and the unwinding belt 3 on the entrance side is rotated.
3 The unwinding belt 32 on the delivery side is run, and the original roll 120 mounted thereon is rotated. The above-mentioned rotation is rotation in the forward and reverse proper directions depending on the winding direction of the original fabric roll 120. The original sheet 105 unwound by the above rotation passes through the sensor 56 (D in FIG. 9).

When the ears of the original 105 pass through the sensor 56, the original 1 is placed between the two pairs of detectors in the left-right direction of the sensor.
If the ears of 05 are located correctly, the running is correct, but if the two pairs of the shift detectors detect or do not detect the ears, it means that the original roll 120 is running abnormally. You have to move either left or right.
The motor 52 for moving the original receiving / receiving member 24 is normally or reversely rotated by the abnormality detection value of the sensor 56. This rotation is transmitted to the beam 18 via the pinion 55 and the rack 54. Beam 18
Is movably mounted on the guide bars 12 and 11 together with the beam 17, so that the beams 17 and 18 are appropriately moved to the left and right, and the original cloth receiving member 24 on the beams 17 and 18 is also moved. . Due to this movement, the ear of the original 105 is the sensor 5
When the normal position is reached within 6, the rotation of the motor 52 is stopped, and the original 105 is fed out at that position, and the original feeding device 5
Of the feeding belt 95, and the running of the feeding belt 95 causes the material 105 to run forward on the feeding belt 95.

The forward movement of the original fabric 105 is predetermined because the original fabric 105 does not enter the sensor 106 provided in front of the unwinding device 5 when the original fabric feeding device 5 moves forward on the spreading carriage 3. Timing, that is, the sensor 5 of the unwinding device 24
It is set to a predetermined time (passage distance / passage time + α) after passing 6 (E in FIG. 9).

Next, the feeding device 5 is moved forward.
At this time, the rotation of the belt 95 of the feeding device 5 is stopped,
The original 105 is sent out from the defibrating device 4. Therefore, a discharge space 125 is formed between the unwinding device 4 and the original feeding device 5. The original fabric 105 that has been released into the discharge space 125 temporarily stays in a U-shape. The sensors 126a, 126b, 127a, 12 shown in FIG. 10 when the U-shaped material 105 extends and the lower end descends.
The position is detected by 7b (A in FIG. 10). At this time, if the upper and lower sensors 126 and 127 are turned on and the upper and lower sensors 126 and 127 are turned on, the solution is stopped, and if the upper sensor 126 is turned off, the solution is restarted (A in FIG. 10).

When the feeding is carried out, the feeding operation is carried out slowly, and it is confirmed that the front end of the material has passed the sensor 106 of the material feeding device 5 without fail (B in FIG. 10). Next, if the exit sensor 128 does not detect the presence of the original fabric even if the original fabric is fed for a predetermined length or more after passing through the sensor, it is treated as an abnormal state and the driving is stopped (C in FIG. 10).

When the original sheet position is detected by the sensor 106 and the original sheet position is detected as abnormal by the sensor, the motor 70 is rotated by the signal to rotate the pinion 7
3, the beam 63 is moved to the right or left on the guide bar 14 via the rack 72, and the original fabric feeding belts mounted on the beams 63 and 64 are moved in the right and left appropriate directions.

[0032]

As described in detail above, the apparatus of the present invention supports the inlet-side defibrating belt and the outlet-side defibrating belt so as to face each other with a support member in a V shape having an open upper side. age,
Since the raw fabric receiving member is rotatably supported by the raw fabric receiving member supporting shaft, and the unraveling belt drive device for driving both the unfolding belts in the forward and reverse directions is provided, the original fabric roll is provided. When the machine is set on the unwinding device, the position where the original fabric roll is on standby and the unwinding belt of the original fabric receiving member of the unwinding device can be positioned at almost the same height, and the standby original fabric can be easily set. , Can be delivered from the standby position onto the original fabric receiving member with extremely little labor. Further, after the original fabric roll is delivered to the unraveling belt of the original fabric receiving member, the original fabric roll can be easily moved to a predetermined position on the original fabric receiving member by the traveling of the unraveling belt. . Further, when the original fabric receiving member swivels, the pair of unraveling belts does not lose the angle of the V-shape, and the other unraveling belt rises up as the unfolding of one unraveling belt falls. Also has an effect that the original fabric roll taken in by the lying belt can be secured at a predetermined position on the original fabric receiving member and stopped.
