Abstract

PURPOSE:To perform the installation position of a material roll so efficiently by making a stopper touchable to a side face of the material roll installed in a chucking means,and controlling on-off operation of this chucking means and movement of the stopper. CONSTITUTION:When an air chuck 16 is made off by a control means, it is outputted to a control valve 24B, and an air cylinder 24 fixes a stopper 18 to a projecting position of a full line. In this state, if a material roll 14 is fitted in the air chuck 16 and this roll is thrust in direction of a frame 22 in parallel with a turning shaft 12, it comes into contact with the stopper 18. Under this state, the air chuck 16 is made on by a control means 20 via a control valve 16B, thereby restraining the material roll 14. Afterward, the control valve 24B is selected by the control means 20, and the stopper 18 is retreated to a retracting position in a two-dot chain line. With this constitution, installation positioning of the material roll 14 to the turning shaft 12 is thus completable.

Conventionally, the positioning of the raw fabric roll relative to the winding bobbin was
Measure the distance from the frame that supports the rotating shaft on which the fabric roll is mounted to the side of the fabric roll, and after adjusting the distance to a constant value, fix the fabric roll to the rotating shaft. was.

[Problem to be solved by the invention]

As mentioned above, each time a roll is mounted, the distance from the side of the roll to the frame must be measured and the position adjusted, so it takes time to position the roll. The immediate problem was that the accuracy was low. On the other hand, it is conceivable to install an edge guide device that automatically positions the original roll, but if this is done, there is a problem that the manufacturing cost increases.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned conventional problems, and is a method for mounting a material roll, which enables the mounting position of the material roll to be determined at low cost, efficiently, and with high precision. The purpose of the present invention is to provide a positioning device.

[Means to solve the problem]

The present invention includes a rotating shaft driven by a motor, a chuck means provided on the rotating shaft that can be inserted into and engaged with a center hole of a material roll, and a chuck means that is movable parallel to the rotating shaft and whose position can be adjusted freely. The mounting positioning device for the fabric roll is configured by a stopper that can come into contact with a side surface of the fabric roll mounted on the chuck means, and a control unit that controls on/off of the chuck device and movement of the stopper. By configuring this, the above object is achieved.

[Function] In this invention, when the raw fabric roll is mounted on the chuck means attached to the rotating shaft, the axial direction of the raw fabric roll is positioned by a stopper that is projected to a predetermined position in advance, and then By fixing the original fabric roll with the chuck means, the original fabric roll can be mounted and positioned efficiently and with high precision. Furthermore, since an expensive edge guide device or the like is not used, the manufacturing cost of the device does not increase significantly.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, this embodiment includes a rotating shaft 12 driven by a motor 10, and a rotary shaft 12 driven by a motor 10.
2, the air chuck 16 is inserted into and engaged with the center hole 14A of the original fabric roll 14, and the air chuck 16 is movable parallel to the rotating shaft 12 and can be freely adjusted in position, and is attached to the air chuck 16. A mounting and positioning device for the fabric roll is configured by a stopper 18 that can come into contact with the side surface of the fabric roll 14, and a control means 20 that controls on/off of the air chuck 16 and movement of the stopper 18. It is something. The rotating shaft 12 is supported by a frame 22 that is perpendicular thereto. The stopper 18 also has a frame 22.
In addition, it is supported by an air cylinder 24 so as to be movable in parallel with the rotating shaft 12. The motor 10 is attached to the frame 22 at a position opposite to the air chuck 16, and is rotated by a gear IOB attached to its output shaft 10A meshing with a gear 12A attached to the rotating shaft 12. The shaft 12 can be driven. The stopper 18 is arranged to be long in the radial direction of the rotating shaft 12. That is, they are arranged so as to be elongated in the radial direction of the original fabric roll 14 mounted on the air chuck 16. Reference numeral 18A in FIG. 1 indicates a guide rod for preventing the stopper 18 from rotating about the central axis of the air cylinder 24 and for guiding the air chuck 16 in the axial direction of the rotating shaft 12. The guide rod 18A is slidably inserted into a guide bush 18B fixed to the frame 22. The protruding position of the stopper 18 is such that it is attached to the air chuck 16 and the side surface of the original roll 4 is located at the stopper 18.
The axial position of the original fabric roll 14 is made to coincide with the axial position of a small-roll bobbin (not shown). Reference numeral 26 in FIG. 1 indicates a guide roller for guiding a web such as a color film unwound from the original fabric roll 14. The fFIJ# means 20 includes a conduit 16A from the compressed air surface 28 to the air chuck 16 and the air cylinder 24;
The air chuck 16 and the air cylinder 24 are operated by switching control valves 16B and 24B placed in the middle of the air chuck 24A. Here, the control means 20 controls the control valve 16 so that the stopper 18 protrudes to a predetermined position when the air chuck 16 is turned off and the web roll 14 is released.
A signal is output to B and 24B. Further, after the air chuck 16 is turned on and the original fabric roll 14 is restrained, the control valves 16B and 24B are controlled so that the stopper 18 is retracted. Next, the operation of the above embodiment will be explained. When the air chuck 16 is turned off by the control means 20, the control means 20 outputs a signal to the control valve 24B, thereby causing the air cylinder 24 to close to the stopper 1.
