Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a winding device that winds up a belt-like body, and in particular, in a printing machine, the belt-like shape of a cleaning device in which various cylinders such as various cylinders and various rollers that are soiled with a solvent such as ink are wiped around a winding shaft. This is effective when the cleaning cloth is removed from the winding shaft.
[0002]
[Prior art]
In the printing machine, for example, when removing the solvent such as ink remaining on the rubber cylinder after the printing is finished, the cleaning device 110 is disposed opposite to the rubber cylinder 101 as shown in FIG. The pad 114 is pressed against the rubber cylinder 101 to bring the belt-shaped cleaning cloth 111 into contact with the rubber cylinder 101, and the winding shaft 113 is rotated while spraying the cleaning liquid onto the cleaning cloth 111, and the cleaning cloth 111 is fed from the holding shaft 112. At the same time, by rotating the rubber cylinder 101, the ink remaining on the peripheral surface of the rubber cylinder 101 is wiped while the cleaning cloth 111 is updated to clean the rubber cylinder 101 (for example, Patent Document 1 below) reference).
[0003]
When the cleaning cloth 111 held by the holding shaft 112 is almost taken up by the take-up shaft 113 after being cleaned in this manner, the holding shaft 112 and the take-up shaft 113 are removed from the cleaning device 110, and a new cleaning cloth is obtained. A holding shaft 112 holding 111 and a new winding shaft 113 are attached to the cleaning device 110, while a used cleaning cloth 111 wound around the removed winding shaft 113 is removed from the winding shaft 113. Thus, the take-up shaft 113 is reused and the removed cleaning cloth 111 is discarded.

The bolts 9, 14a, 14b, the fitting holes 10a, 15a and the like constitute engaging means.
[0022]
Using the winding device according to the present embodiment configured as described above, for example, a used belt-shaped cleaning cloth of a cleaning device that removes ink remaining on a rubber cylinder or the like of a printing press Next, the case of winding will be described.
[0023]
First, the winding shaft 113 around which the used cleaning cloth 111 is wound is removed from the cleaning device, and one of the mounting shafts 3a is moved away from the other mounting shaft 3b to move the mounting shafts 3a and 3b. After extending the interval, one end of the winding shaft 113 is fitted coaxially to one of the mounting shafts 3a, and the other end of the winding shaft 113 is fitted coaxially to the other mounting shaft 3b. When combined, the compression coil spring 5 urges the mounting shaft 3a in a direction to approach the other mounting shaft 3b, so that the winding shaft 113 is rotatably supported by the mounting shafts 3a and 3b.
[0024]
Next, when the exposed end of the cleaning cloth 111 is covered with the winding rods 11a and 11b so as to cover the winding rods 11a and 11b and the support shaft 6b is rotated via the handle lever 13, the bolt Since the support block 15 rotates via 14a and 14b and the winding rods 11a and 11b revolve around the support shaft 6b, the cleaning cloth 111 is moved from the winding shaft 113 to the winding rods 11a and 11b. 11b is wound up.
[0025]
When the cleaning cloth 111 is wound around the winding rods 11a and 11b from the winding shaft 113 in this way, the winding shaft 113 is removed from the mounting shafts 3a and 3b in the reverse procedure to that described above, while the compression coil spring 8 The support shaft 6b is moved away from the support shaft 6a so as to resist the urging force, and the interval between the support shafts 6a and 6b is widened. The fitting hole 15a is extracted and the fitting hole 10a of the support plate 10 is extracted from the head of the bolt 9 of the support shaft 6b, whereby the cleaning cloth 111 wound around the take-up rods 11a and 11b is removed from the support plate 10. Then, it is taken out from between the support shafts 6a and 6b together with the support block 15 and the like.
[0026]
When the set screw 15c of the support block 15 is loosened to divide the support hole 15b in the axial direction and the support block 15 is removed from the shaft ends of the take-up rods 11a and 11b, the take-up rods 11a and 11b The other end is loosely fitted into the support hole 10b of the support plate 10 while the other end is restricted from moving in the axial direction relative to the support plate 10 by the hollow sets 12a and 12b. Therefore, it can swing around the hollow sets 12a and 12b.
[0027]
Here, when the winding rods 11a and 11b are swung so as to approach one of the opened shaft ends of the winding rods 11a and 11b, the cleaning cloth 111 wound around the winding rods 11a and 11b. Can be easily extracted from one open end of the winding rods 11a and 11b, and can be removed from the winding rods 11a and 11b while the cleaning cloth 111 is wound up.
[0028]
When the cleaning cloth 111 is removed from the take-up bars 11a and 11b in this way, the support block 15 is attached to one end of the take-up bars 11a and 11b in the reverse order to the above, and the support plate 10 and the support block 15 are attached. Are attached to the support shafts 6a and 6b.
[0029]
Therefore, according to the present embodiment, the used cleaning cloth 111 wound around the winding shaft 113 can be easily detached from the winding shaft 113 and the used cleaning removed from the winding shaft 113 is used. The cloth 111 can be held in a wound state, and the space required for storage can be greatly reduced.
[0030]
In addition, since the cleaning cloth 111 is wound up using the plurality of winding rods 11a and 11b, the cleaning cloth 111 can be wound up quickly.
[0031]
In the present embodiment, the support block 15 is rotated by the handle lever 13, but instead, the support block 15 may be rotated by a motor, for example.
[0032]
In the present embodiment, the other ends of the two winding rods 11a and 11b are supported so as to be swingable. However, the other end of at least one winding rod is supported so as to be swingable. Then, the same effect as the case of this Embodiment can be acquired.
[0033]
Further, in the present embodiment, the other ends of the winding rods 11a and 11b are loosely fitted into the support holes 10b of the support plate 10 and the hollow sets 12a and 12b are attached to swing the winding rods 11a and 11b. In another embodiment, for example, as shown in FIG. 8, the other ends of the winding rods 21a and 21b made of an elastic material such as rubber are supported by the support plate 20, as shown in FIG. It is also possible to remove the cleaning cloth 111 by fitting it into the hole 20b and fixing it with bolts 22a and 22b and elastically deforming the winding rods 21a and 21b.
[0034]
Further, in this embodiment, the cleaning cloth 111 is wound up by the two winding bars 11a and 11b. However, it is possible to provide three or more winding bars to wind up the cleaning cloth 111. It is. At this time, if the other end side of at least one winding rod is supported so as to be swingable, the same effect as in the case of the present embodiment can be obtained.
[0035]
In the present embodiment, the case where the used belt-like cleaning cloth of the cleaning device from which the solvent such as ink remaining on the rubber cylinder of the printing machine has been removed is wound up is described. However, the present invention is not limited to this, and the present invention can be applied in the same manner as described above in the present embodiment as long as the strip is easily removed from the winding shaft around which the strip is wound to be compact.
[0036]
【The invention's effect】
In the winding device according to the present invention, for example, a used belt-like cleaning cloth of a cleaning device from which a solvent such as ink remaining on a cylinder such as a rubber cylinder of a printing press or a roller such as a chill roll is removed is wound up. If applied to the case, the used cleaning cloth wound around the winding shaft can be easily removed from the winding shaft, and the used cleaning cloth removed from the winding shaft is held in a wound state. And the space required for storage can be greatly reduced.
