2. Description of the Related Art In general, a raw material is wound in a roll shape, and when it is cut, the material is unwound and developed, and a required number of sheets are stacked and cut into a desired shape. When unwinding the web roll, the web roll is supported by a support member, and its supporting means is inserted on a plurality of receiving rolls by inserting a shaft into the center of the web wound in a roll shape. Various operations are performed, such as placing a raw roll, receiving a raw roll on a plurality of belts instead of a plurality of receiving rolls, and in any case, pulling out and releasing the rolled fabric Therefore, the drawn-out web may have a small amount of elongation or contraction due to a delicate curl or a part. Therefore, when unrolling and unrolling the roll, the roll may be passed through a space in a free state to provide a means for recovering the unrolled roll. In addition, after receiving the unwound raw material from the unwinding device in an unfolded state and receiving the unwound raw material into the unrolling device, the raw material is stacked on a spreading table. The work has to be handed over and the work has been done manually.
This work was extremely labor intensive because it was not possible to handle the material in such a manner as to cause an unnecessary change in tension. In particular, it was a hard work for a wide web such as a W width.

[0003]

SUMMARY OF THE INVENTION In view of the above points, the present invention provides a fully automatic sheet feeding device that unwinds a material roll unwound from a material roll on a sheet unwinding device without introducing any manual operation. It is an object of the present invention to obtain a reversing device that can perform the above-mentioned operation and can also form a release space.

[0005]

The rolling machine according to the present invention is constructed by movably mounting a breaking device and a web feeding device on a rolling cart that extends a web on a rolling table, and starts work. At first, a raw roll is placed on the de-rolling device. The unroller pulls out the web from the web roll while rotating the web roll, but when transferring the tip of the web to the web feeder,
Either or both of the raw material feeding device and the releasing device approach each other, and the receiving side of the raw material feeding belt of the raw material feeding device is located below the raw material feeding side end of the raw material roll support member of the releasing device. The end portion enters, and the raw material feeding belt receives the raw material that has been sent out from the release device and hangs down. The raw material feeding belt runs in synchronization with the releasing speed of the releasing device and receives the raw material, but after receiving the raw material, one or both devices are moved so that a space is formed between the two devices. The above space becomes a repelling space, and the raw material sent out from the release device is temporarily not supported by anything in the releasing space, and the tension applied to the raw material at that time is released.

In the embodiment described above, the moving means of the raw material feeding belt is provided so that the raw material feeding belt of the raw material feeding device approaches and separates from the releasing device. Even if the moving means is provided on the material receiving member of the apparatus,
Alternatively, it goes without saying that moving means may be provided in both devices.

Next, the procedure for rolling the raw material by the apparatus of the present invention will be described.

First, the material roll 120 is placed on the material receiving member 24 of the release device 4. To do so, as shown in FIG.
The material receiving member 24 must be lowered. Material receiving member 2
The angle at which the sheet roll 4 is tilted must be such that the sheet roll 120 does not fall off the sheet receiving member 24. This angle is determined in advance, and a sensor (not shown) is provided at a predetermined angle position.

The turning motor 37 of the material receiving member 24 is rotated, and the swing arm 34 is turned via the arm 38 slider 36. Since the swing arm 34 is formed integrally with the V-shaped arm 25, the swinging of the swing arm 34 causes the V-shaped arm 25 to turn and stop at that position when corresponding to a sensor (not shown) (FIG. 9). A). This stop position is opposed to the standby position of the material roll, and the material roll is carried into the material receiving member 24 manually or by a carrying-in device (B in FIG. 9).

Thereafter, the original web receiving member 24 is brought into the upright position by the rotation of the motor 37 in the reverse direction (C in FIG. 9). At this point, the motors 39a and 39b are rotated, and the release belt 3 on the entry side is rotated.
(3) Run the unwinding belt 32 on the exit side, and rotate the raw roll 120 on it. The rotation is a rotation in an appropriate direction in the normal or reverse direction according to the winding direction of the material roll 120. The web 105 released by the rotation passes through the sensor 56 (D in FIG. 9).

When the ear of the web 105 passes through the sensor 56, the web 1 is located between two pairs of detectors in the left and right direction of the sensor.
If the ear 05 is located, the running is correct, but if either of the two detectors detects or does not detect the ear, it means that the vehicle is running abnormally. Must be moved to the left or right.
The motor 52 for moving the raw material receiving member 24 is rotated forward and backward based on the abnormality detection value of the sensor 56. This rotation is transmitted to the beam 18 via the pinion 55 and the rack 55. Beam 18
Is movably mounted on the guide bars 12 and 11 together with the beams 17, so that the beams 17 and 18 are moved to the right and left as appropriate, and the material receiving member 24 on the beams 17 and 18 is also moved. . Due to this movement, the ear of the raw material 105 becomes the sensor 5
6, the rotation of the motor 52 is stopped, and the web 105 is sent out at that position, and the web feeder 5
The original web 105 travels on the feeding belt 95 forward by the running of the feeding belt 95.

When the web 105 that has run forward falls from the front end of the feeding belt 95, the web 105 moves forward when the web feeding device 5 moves forward on the rolling cart 3. (E in FIG. 9) at a predetermined timing, that is, at a predetermined time (passing distance / passing time + α) after the passage of the sensor 56 of the deflector 24.

Next, the feeding device 5 is advanced.
At this time, the rotation of the belt 95 of the feeding device 5 stops,
The raw material 105 is sent out from the breaking device 4. Therefore, a release space 125 is formed between the release device 4 and the raw material feeding device 5. The web 105 released in the release space 125 temporarily stays in a U-shape. When the U-shaped web 105 extends and its lower end is lowered, the sensors 126a, 126b, 127a, and 12 shown in FIG.
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 due to the raw material dripping too much, the solution is stopped, and if the upper sensor 126 is turned off, the solution is restarted (A in FIG. 10).

When the feeding operation is performed, the operation is set to the slow operation, and it is confirmed that the leading end of the material has always passed the sensor 106 of the material feeding device 5 (FIG. 10B). Next, if the exit sensor 108 does not detect the presence of a raw web even if the raw web has been 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 is detected by the sensor 106 and the position of the original sheet is detected as abnormal by the sensor, the motor 70 is rotated by the signal and the pinion 2 is rotated.
3. The beam 63 is shifted right or left on the guide bar 14 via the rack 72, and the raw material feeding belt mounted on the beams 63 and 64 is moved in the right and left appropriate directions.

[0032]

As described in detail above, the apparatus of the present invention comprises a sheet releasing device for releasing a sheet roll and a sheet feeding device having a feed belt for placing and transferring the separated sheet.
Either or both of the release device and the raw material feeding device can approach and separate from the counterpart device, and when the two devices approach, the receiving end of the feeding belt is connected to the release device sending end. The two devices are placed on a reversing trolley so that when the two devices are separated, a release space is created between the two devices. At the time of delivery, the released material is guided directly onto the material supply belt of the material supply device and is placed on the belt, so that no manual operation is required, and the material guide is provided. No device is required, and even a raw material having a large width such as a W width can be easily set on a machine.

Further, since a release space can be formed between the release device and the raw material feeding device, even when the raw material has irregular tension, it is possible to recover it uniformly.
