ス角度で切断される。BACKGROUND OF THE INVENTION As shown in Japanese Patent Laid-Open No. 2-223431, an apparatus for cutting a band-shaped member of this kind is provided with a fan-shaped fixed table at the rear of the cutting machine and in contact with the cutting machine. Some devices are equipped with a turning table (carrying device) that can turn along the rear edge of the arcuate shape. The strip member to be cut is fed onto a fan-shaped fixed table through a revolving table in a direction defined by the revolving table, and its leading end is sucked by a feeding suction means disposed on the fan-shaped fixed table. It is sent in the same direction to the cutting machine in front, and is cut by the cutting machine. Since the cutting line by the cutting machine is inclined with respect to the feeding direction of the strip-shaped member, the strip-shaped member is cut at a desired bias angle.

旋回させて角度変更を行うようにしてある。When the rotating table is rotated along the arc-shaped rear edge of the fan-shaped fixed table, the direction in which the strip member is carried into the fan-shaped fixed table, and therefore the angle of the cutting line with respect to the strip member changes, so the rotating table is rotated. This allows the bias angle of the cutting line to be changed. However, when changing the angle, the part of the band member on the fan-shaped fixed table is easily deformed due to friction with the table, so there are various problems such as the need for rework. The angle is changed by rotating the belt-like member at a predetermined angle together with the rotating table while the distal end side of the belt-like member is suction-held by the auxiliary suction means that rotates together with the table.

時間を要した。[Problem to be solved] In the above-mentioned belt-shaped member cutting device, the belt-shaped member is usually unwound from a raw roll containing a long belt-shaped member to be cut, and fixed in a fan shape through a revolving table by a pull roll. It is fed out onto the table, then adsorbed by the feeding suction means and sent to the cutting machine. However, at the start of work, the tip of the strip member is manually moved from the pull roll to the feeding suction means position on the fan-shaped fixed table. It must be guided and transported. Furthermore, when rewinding the strip material onto the original roll at the end of the work or when changing the strip material, it is necessary to manually guide the tip end to the pull roll, which conventionally requires a large amount of manual labor. It took a long time to change the setup.

There is. Furthermore, since the position of the auxiliary suction means overlaps with the movement range of the feeding suction means, when changing the angle, the feeding suction means that has sucked the strip member and retreated a certain amount is retracted to its forward limit, and then the auxiliary suction means is moved. The suction means must be operated, and after changing the angle, the auxiliary suction means must be moved to the standby position.
Operation and structure become complicated.

できる。[0007] In this band-shaped member cutting device, as a preparatory work at the start of work, in order to guide the leading end of the band-shaped member unwound from the original fabric roll to a predetermined position on the fixed table, the carry-in device is first moved backward. The leading end of the strip member sent out from the pull roll is received on a strip conveyor means such as a belt conveyor and advanced by an appropriate amount, and then the strip member is moved to a position below the pull roll. The loading device is advanced to a position where it touches the fixed table while being fed out by the pull roll. Then, the conveying means is operated at a speed commensurate with the feeding speed of the pull roll, and the belt-like member is advanced until its leading end reaches a predetermined position on the fixed table. At this point, if the conveying means is stopped and the pull roll further sends out an appropriate amount of the strip member, a downwardly hanging margin can be formed between the carry-in device and the pull roll.

剛性が高く帯上部材にはしわが発生しない。[0009] When changing the angle, the conveying means is operated in the unwinding direction together with the pull roll to retract the strip member until its front end reaches the top of the carry-in device, and then the carry-in device is rotated. The front end will not be deformed due to friction with the fixed table. After setting the angle, the strip member is sent out again to the suction bar operating range on the fixed table by the pull roll and the conveying means. At this time, since a reinforcing cord (for example, a steel cord, etc.) is embedded in the strip member in the feeding direction, the strip member has high rigidity in this direction and wrinkles do not occur in the strip member.

。When changing the angle, the belt conveyor 20 is operated in the unwinding direction together with the pull roll 24 from the state shown in FIG. Thereafter, the turning table 10 is turned to change the direction in which the belt-shaped member is carried in, for example, from a to a' (FIG. 2). Since the band member 5 is completely detached from the fixed table 2 during turning, it will not be deformed due to friction with the fixed table 2. After setting the angle in this way, the belt conveyor 20 is operated in the delivery direction together with the pull roll 24 to advance the front end of the strip member 5 onto the fixed table 2 again. In this embodiment, the belt conveyor 20 is used as the belt-shaped member guide portion of the carrying-in device 3, so that the belt-shaped member 5 can be driven and conveyed by the belt conveyor 20, so that the belt-shaped member 5 can be quickly moved backward and forward when the angle is changed. and can be performed accurately. Therefore, even if the strip member 5 is retreated to a rear position beyond the operating range of the suction bar 6, that is, above the carry-in device 3, it can be easily returned forward to within the operating range of the suction bar 6 after changing the angle. Unlike the conventional example, it is not necessary to take measures such as providing a separate auxiliary suction means in order to keep the retreat of the strip member 5 within the operating range of the suction bar 6 and to separate the strip member 5 from the upper surface of the fixed table 2.

This can be carried out without the need for acquisition by means of the means and means for moving the carrying-in device, and therefore the manual work is greatly reduced, and the time required for changeover is also significantly shortened. Furthermore, it is possible to completely prevent the belt-like member from deforming due to friction with the fixed table when changing the angle.
