Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an improvement in a device for winding up wallpaper or other printing paper.

[Prior art]

When the winding shaft is rotated and paper is wound into a roll on the winding shaft, the paper comes into pressure contact with the outer surface of the winding shaft, making it difficult to pull out the winding shaft from the roll of paper. Sometimes.

As a countermeasure against this, in the case of a conventional paper winding device, a protrusion support member having a paper receiving protrusion disposed inside the opening is provided in the winding shaft having an opening in the peripheral wall, and the winding A protruding and retracting operation device is provided at the end of the shaft for causing the paper receiving projection to protrude from or retract from the outer surface of the winding shaft, and the paper receiving projection is made to project from the outer surface of the winding shaft. In this state, the winding shaft is rotated by a drive device to wind up a predetermined amount of paper on the winding shaft in a roll shape, and then the winding shaft is taken out from the rotation drive part of the paper winding device, Next, the protruding and retracting operating device is manually operated to retract the paper receiving protrusion so that it does not protrude from the outer surface of the winding shaft, and then the winding shaft is pulled out from the roll of paper, and then the protruding and retracting operating device is operated. After the paper receiving protrusion is made to protrude from the outer surface of the winding shaft by manual operation, the winding shaft is set in a rotation drive section of the paper winding device.

However, in the conventional case, it is necessary to remove the winding shaft on which the paper is wound from the rotary drive section of the paper winding device before pulling the winding shaft from the paper roll, and then manually operate the protruding and retracting operating device. The paper receiving projection must be retracted, and after the winding shaft has been pulled out from the web, the paper receiving projection must be protruded again by manual operation of the protrusion/retraction operating device, and then the winding shaft must be retracted. Since it must be set in the rotation drive part of the paper winding device, it requires complicated operations and takes a long time to complete the preparation for the next winding after all paper winding is completed. There's a problem.

〔Effect of the invention〕

According to this invention, by simply rotating the winding shaft 1 to the paper winding position, the pushing operation member 8 provided on the frame 2
The protruding operating member 7 is automatically pushed and moved,
The protrusion mechanism provided between the protrusion operating member 7 and the protrusion support member 5 allows the paper receiving protrusion 4 to automatically protrude from the opening 5 of the winding shaft 1. After winding up a predetermined amount of paper into a roll, simply roll the winding shaft 1 and the paper wound around it into a roll, that is, the roll paper 85, at one end of the winding shaft 1 attached to the frame 2. By turning the protruding operating member 7 around the center and separating the protruding operating member 7 from the pushing operating member 8, the protruding operating member 7 is automatically pushed and moved by the force of the push-out position holding spring 6, and the paper receiving protrusion is moved. 4 can be moved to a non-protruding position, so that the roll paper 85 can be easily pulled out from the winding shaft 1 by simply rotating the winding shaft 1 and the roll paper 85 after winding the paper. Furthermore, there is no need to remove the entire winding shaft 1 from the rotating drive section of the paper winding device, and the paper receiving protrusions 4 can be switched between the fully protruding position and the non-protruding position simply by rotating the winding shaft 1. Roll paper 85 after paper winding is completed
It is possible to easily and quickly perform sampling and preparation for the next paper roll. Further, a retracting slope 10 that is engaged with a pressing edge 9 on the winding shaft front end side in the opening 5 of the winding shaft 1 is provided at the end of the paper receiving projection 4 on the winding shaft front end side. Otherwise, when the protrusion support member 5 is moved toward the tip end of the winding shaft by the force of the extrusion position holding spring 6, it engages with the retracting slope 10''f and the pressing edge 9, and presses the paper. The receiving protrusion 4 and the protrusion support member 5 can be forcibly moved in the paper receiving protrusion retraction direction, so even if the paper receiving protrusion 4 is facing in any direction such as downward or sideways, the extrusion position holding spring 6 is When the protrusion support member 5 is moved toward the tip end of the winding shaft by force, the paper receiving protrusion 4 can be automatically and reliably moved to the non-protruding position.
