Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a fabric cut ear collecting device that sucks cut ears of a cloth into a duct and continuously collects the ears.

[0002]

[Prior Art]

 For example, before winding the finished fabric on a take-up roll, it is required to cut the ears of the fabric with a cutter and to continuously collect the ears, and a suction device is used as the collecting device. In the suction type recovery device, one end of the duct is arranged close to the cutter, a blower is provided at the other end of the duct, and the inside of the duct is evacuated by the blower. Therefore, the cut ears of the cloth can be sucked into the duct and continuously collected.

[0003]

[Problems to be solved by the device]

 Conventionally, this device has various problems. For example, the ears of the fabric may not be cut for some reason, and the uncut ears may be sent untouched until an operator discovers it. The ears of the cloth are not sucked by the blower and the traverse of the duct, and the cut ears of the cloth are accumulated between the cutter and the duct, which may cause defective cloth. The accumulated fabric may damage the device. In some cases, the cut ears of the cut fabric are inadvertently cut off between the cutter and the duct, and it hangs downward and is not sucked into the duct.

[0004] Therefore, according to the present invention, in the cut ear collecting device for a cloth that sucks the cut ears of the cloth into the duct and continuously collects the ears, the ears of the cloth are not cut, and the ears of the cloth Even if a piece was cut, it was designed to deal with it properly when it was not sucked into the duct and continuously collected.

[0005]

[Means for Solving the Problems]

 According to this invention, the roller is provided in the duct and is attached to the support shaft, and the support shaft is arranged so as to extend in a direction intersecting with the suction direction of the cloth ear, and the cloth ear is provided on the outer peripheral surface of the roller. Engage with. Further, an encoder is connected to the shaft of the roller, and the encoder detects the rotation of the roller.

[0006]

【Example】

 An embodiment of this invention will be described below.

In FIG. 1 and FIG. 2, this device is an accessory device of the finishing device, which cuts and collects the ears 2 of the cloth 1, and has a cutter 3. The cutter 3 is a rotary cutter and is connected to the motor 4. Therefore, the cutter 4 is driven and rotated by the motor 4, the finished fabric 1 is fed to the left in FIG. 2, guided to the cutter 3, and the ear 2 of the fabric 1 can be cut by the cutter 3. .. After that, the cloth 1 with the ears 2 cut is guided to the exit device and then wound up by another device. This device is of a suction type and has an elongated duct 5, one end of which is arranged close to the cutter 3. Further, a blower 6 and a collection tank 7 are provided at the other end of the duct 5, and the inside of the duct 5 is evacuated by the blower 6. Therefore, the cut ears 2 of the cloth 1 can be sucked into the duct 5, continuously collected, and stored in the collection tank 7.

Furthermore, this device has a roller 8 and an encoder 9, which is provided in the duct 5 and is attached to the support shaft 10, which is in a direction intersecting with the suction direction of the ear 2 of the cloth 1. It extends and is rotatably supported. Then, the ears 2 of the cloth 1 are guided to and engage with the outer peripheral surface of the roller 8. Further, the support shaft 10 of the roller 8 projects to the outside of the duct 5, and the support shaft 10 is connected to the encoder 9. The encoder 9 is connected to the control device 11 and the control device 11 is connected to the alarm device 12. Has been done. Therefore, when the ears 2 of the cloth 1 are sucked into the duct 5 and continuously collected, the ears 2 of the cloth 1 move in the duct 5, and the friction thereof acts on the roller 8. This causes the roller 8 and the support shaft 10 to rotate, which is detected by the encoder 9.

Further, in this embodiment, a separate roller 13 is provided on the downstream side of the roller 8, and the roller 13 is also attached to the support shaft, so that the selvage 2 of the cloth 1 passes above the roller 8 and It is guided to the lower side of the roller 13. Therefore, the selvage 2 of the cloth 1 engages the roller 8 with a large contact area, slip does not occur between the selvage 2 and the roller 8 of the cloth 1, and the roller 8 can be reliably rotated. Further, on the downstream side of the roller 13, a duct 5 is formed of a transparent material, the duct 5 is partially reduced, and a photo sensor 14 is provided outside the duct 5. The photo sensor 14 is for detecting the ears 2 of the cloth 1, and is connected to the control device 11.

Therefore, in this device, when the ear 2 of the cloth 1 is not cut by the cutter 3, the ear 2 is not sucked into the duct 5 and does not move in the duct 5. Therefore, the roller 8 does not rotate. Even if the ears 2 of the cloth 1 are cut, when the ears 2 of the cut cloth 1 are not sucked into the duct 5 and are not continuously collected, the ears 2 of the cloth 1 are not drawn. It does not move inside and the roller 8 does not rotate. Therefore, the encoder 9 detects it, the detection signal is sent to the control device 11, and the control device 11 drives the alarm device 12. Therefore, it is possible to quickly recognize an abnormal situation and deal with it appropriately.

Further, in this embodiment, even if the encoder 9 malfunctions, when the ear 2 of the cloth 1 is not inside the duct 5, the photo sensor 14 detects it and the detection signal is sent to the control device 11. Sent. Therefore, the alarm device 12 can be driven by the control device 11, which is safe.

[0012]

[Effect of the device]

 As described above, according to the present invention, when the ears 2 of the cloth 1 are not cut by the cutter 3, the rollers 8 and the encoder 9 can detect the ears 2. Even if the ears 2 of the cloth 1 are cut, when the cut ears 2 of the cloth 1 are not sucked into the duct 5 and are not continuously collected, similarly, the roller 8 and the encoder 9 are used. It can be detected. Therefore, it is possible to quickly recognize an abnormal situation, deal with it appropriately, and achieve the intended purpose.
