[Industrial applications]

 The present invention relates to a cleaning web roller supporting device for supporting a cleaning web roller provided in a cleaning device for cleaning a printing cylinder such as a blanket cylinder and an impression cylinder, and a roller such as an attachment roller and a swing roller in various printing machines. is there.

[0002]

[Prior art]

 Various types of printing machines such as offset printing machines and intaglio printing machines are equipped with printing cylinders such as plate cylinders, blanket cylinders, impression cylinders, and rollers such as adhering rollers and swing rollers. Since foreign substances such as ink residue and paper dust adhere to the printed matter to deteriorate the quality of the printed matter during the printing operation, a cleaning device for removing these foreign substances is provided.

For example, when cleaning a blanket cylinder, this type of cleaning device extends in the axial direction in the vicinity of the peripheral surface of the blanket cylinder, and has both ends thereof rotatably supported by bearings of a device frame. A supply roller and a take-up roller are provided, and a belt-shaped cleaning web (hereinafter simply referred to as a web) made of a nonwoven fabric or the like is wound on the supply roller in a separate step. Then, the web is wound on the take-up roller after being pressed against the peripheral surface of the ink roller by a guide roller or a pad provided between the supply roller and the take-up roller.

With such a configuration, when the blanket cylinder is rotated and the take-up roller is intermittently rotated, the web runs intermittently and foreign matter attached to the peripheral surface of the blanket cylinder is removed. It is wiped off with and transferred to the web, and the web is taken up by a take-up roller with foreign matter attached.

Further, when cleaning the ink roller, for example, a device is used that scrapes off the foreign matter attached to the peripheral surface of the ink roller with a doctor. That is, in this device, the web that is unwound from the supply roller and faces the take-up roller is separated from the peripheral surface of the ink roller, and the rear end portion of the web is abutted against the web between the supply roller and the take-up roller. A doctor whose tip is in contact with the peripheral surface of the ink roller is provided.

With this configuration, when the front end of the doctor is brought into contact with the peripheral surface of the ink roller, and then the blanket cylinder is rotated and the take-up roller is intermittently rotated, the web is intermittently rotated. The foreign matter adhering to the peripheral surface of the ink roller as it travels is scraped off by a doctor, moves on the plane of this doctor, and then transfers to the web.The web is wound around the take-up roller with the foreign matter attached. Taken.

In each of these two types of cleaning devices, when the web on the supply roller is exhausted, the empty supply roller is removed from the supporting member on the apparatus frame side, and instead the web is fully wound. The work of mounting the supply roller and replacing the take-up roller with the full web wound in the same way with an empty take-up roller is performed. In addition, when cleaning is not performed, the entire cleaning device is removed from the machine and stored.

As described above, in the web cleaning apparatus attached to the printing press, the supply roller and the take-up roller must be replaced each time the supply roller becomes empty, and the cleaning roller is not used when cleaning is not performed. Since the entire device must be removed from the machine, a cleaning web roller support device has been conventionally provided on the device frame side to detachably support the supply roller and the winding roller as these cleaning web rollers. .

[0009]

[Problems to be solved by the device]

 However, since the conventional cleaning web roller supporting device fixes and holds the hollow core material of the web roller around which the web is wound by sandwiching the hollow core material from both ends with the fixing metal fittings, the web is fixed. Wrinkles are formed on both ends of the web roller, and when the web roller is removed, the fixing metal fittings bite into the hollow core material of the web roller, making it difficult to remove and the workability is poor. There is a problem that the width of the machine becomes wider and the machine becomes larger.

The present invention has been made in view of the above points, and an object of the present invention is to provide a cleaning web roller supporting device for a printing machine, in which the web roller can be easily attached and detached and the size of the machine can be reduced.

[0011]

[Means for Solving the Problems]

 In order to achieve such an object, according to the present invention, a cleaning web roller supporting device of a printing machine, which supports a hollow web roller around which a cleaning web is wound, is formed so as to be expandable and contractible in a radial direction. And a fixing member fitted in the inner hole of the fixing member, and formed so as to be movable in the axial direction by being engaged with the fixing member. The movement presses the fixing member in the axial direction to expand the fixing member in the radial direction. The web roller and the fixing member are fixed to each other by a pressing member.

[0012]

[Action]

 For example, when a supply roller as a web roller around which a cleaning web is wound is assembled and attached to the apparatus frame, first, for example, the central shaft forming the pressing member is. After inserting it into the inner hole of the supply roller and fitting the fixing members made of elastic material to both ends of the supply roller while fitting it into the inner hole of the supply roller, part of the pressing member is moved in the axial direction and fixed. When the member is pressed, the fixing member expands in the radial direction, and the web roller and the fixing member are fixed to each other. After that, when the pressing member is fitted to the holder on the apparatus frame side, the supply roller is attached to the apparatus frame.
