Abstract

(57) [Abstract] [PROBLEMS] To improve efficiency of cleaning sheet roll replacement work. SOLUTION: A cleaning sheet roll 26 is formed by adhering a winding start end of a cleaning sheet 24 to a surface of a paper tube 42 and winding it up. An adhesive tape is provided on the surface of the paper tube 42. A release paper is attached to the adhesive tape to prevent it from sticking to the cleaning sheet 24 that comes into contact therewith. When the cleaning sheet roll 26 having such a structure is used for cleaning the cylinder of the printing press, first, the cleaning sheet roll 2
6 is used as a supply roll, and the paper tube 42 is used as a take-up tube after the use. At this time, the tip of the cleaning sheet of the new roll is fixed to the paper tube 42 by the adhesive tape of the paper tube 42. Since the paper tube 42 can be discarded together with the used cleaning sheet 24, the work efficiency can be improved. Further, since the unwinding operation of the cleaning sheet 24 is deleted, it is possible to prevent the scattering or adhesion of paper dust or printing ink, and to provide a comfortable working environment for the worker.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning sheet roll core tube material used for cleaning a printing press cylinder such as a blanket cylinder of an offset printing press.

[0002]

2. Description of the Related Art A cylinder of a printing machine such as a blanket cylinder is regularly cleaned because the surface of the printing machine is contaminated over time. A cleaning device using a cleaning sheet is used for cleaning the surface of such a printing press cylinder. This makes it possible to run a cleaning sheet made of a non-woven fabric impregnated with a cleaning liquid in the pressing part that can be brought into and out of contact with the surface of the printing machine cylinder
By moving the pressing portion in contact with the cylinder surface during the cleaning work, the nip pressure of the pressing portion and the rotation of the printing cylinder are used to wipe off surface stains. Conventionally, this type of cleaning device arranges a cleaning sheet roll, which serves as a supply roll, behind a pressing portion having a length corresponding to the body length of a printing machine cylinder to be cleaned. With the cleaning sheet roll, a paper tube is used as a core tube material, the surface of the paper tube and the winding start end of the cleaning sheet are fixed with an adhesive serving as a fixing means, and the cleaning sheet is rolled up on the paper tube. It is a thing. On the winding side, a metal shaft for winding that serves as a winding tube is arranged. In order to attach a cleaning sheet to the winding metal shaft, a method of blasting the surface of which has a high friction coefficient or a method of adhering and fixing a wrap having unevenness is performed. Alternatively, a method of directly attaching a winding metal shaft and a cleaning sheet with a tape is also used. In the method of attaching the winding metal shaft and the cleaning sheet using this tape, first, a fixing tape is prepared, and the tape is cut so as to correspond to the cleaning sheet width. Then, the cleaning sheet is positioned on the metal shaft for winding and both are fixed by the cut tape.

After the cleaning sheet is thus installed in the cleaning device, the cylinder is cleaned while the cleaning metal shaft is intermittently rotated to wind the cleaning sheet onto the winding metal shaft. ing.

When the cleaning sheet is wound on the winding metal shaft and the cleaning sheet roll runs out of cleaning sheets, the pressing portion of the cleaning device is disengaged from the cylinder of the printing press to stop the cleaning device. After the cleaning device is stopped, the operator removes the adhesive portion of the paper tube in the cleaning sheet roll or cuts the winding start end of the cleaning sheet with a tape cutter or the like, and removes the cleaning sheet from the paper tube. Then, remove the paper tube and the winding metal shaft around which the used cleaning sheet is wound from the cleaning device, move it to another location, unwind the cleaning sheet from the winding metal shaft, and then re-use the original paper. Wrap it around the tube. The used cleaning sheet wound around the original paper tube is discarded together with the paper tube.
Alternatively, the cleaning sheet is unwound from the winding metal shaft, and both the cleaning sheet and the paper tube are discarded. After the end of the discarding work, a new cleaning sheet roll is placed in the cleaning device, the cleaning sheet is attached again to the winding metal shaft, and the cylinder of the printing press is cleaned.

[0005]

By the way, in order to remove the used cleaning sheet from the cleaning device, a manual operation by an operator is involved. In particular, the cleaning sheet is unwound from the winding metal shaft, and then the cleaning sheet is again transferred to the paper tube. The wrapping work required a great deal of time. This has been an obstacle to improving the efficiency of the cleaning work. Also, since the cleaning sheet has already been used, paper dust and printing ink from the cylinder of the printing press are attached to the surface of the cleaning sheet, and these deposits stain the clothes of the worker and the exposed parts of the clothes. There was a possibility. Therefore, it is not a comfortable working environment for workers, and improvement of the working environment has been demanded.

A winding metal shaft is used to wind up the cleaning sheet. The surface of the winding metal shaft is subjected to surface treatment to increase the coefficient of friction, or has an uneven surface. I had to fix the wrap with adhesive. Therefore, there is a problem that an expensive metal shaft for winding must be purchased. Further, in the method of directly attaching the winding metal shaft and the cleaning sheet with the tape, it is necessary to perform the simultaneous work of positioning the cleaning sheet on the winding metal shaft and fixing the both with the tape. However, this simultaneous work is highly difficult, and there is a possibility that the relative position between the cleaning sheet and the winding metal shaft may change when the tape is attached. Then, due to the change in the relative position, when the used cleaning sheet is wound on the winding metal shaft, winding disorder may occur. In addition, it took time and effort to attach the tape, which hindered the work.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and it is an object of the present invention to improve the working efficiency in replacement of the cleaning sheet and the working environment.

[0008]

SUMMARY OF THE INVENTION The present invention eliminates the work of unwinding a used cleaning sheet from the take-up tube by using a disposable take-up tube on the take-up side of the wash sheet, and the take-up tube This is done by paying attention to the fact that if the fixing means for fixing the cleaning sheet is provided in advance, the cleaning sheet can be easily attached. That is, the core tube material of the cleaning sheet roll according to the present invention is the core tube material of the cleaning sheet roll used in the printer cylinder cleaning device, and the core tube material is provided with a second means other than the fixing means for the winding start end of the cleaning sheet. Fixing means is provided, and after the cleaning sheet roll is used as a supply roll, the core sheet material is used as a take-up tube of the printer cylinder cleaning device, and the tip of the cleaning sheet fed from a new supply roll is used as the second sheet. It is configured so that it can be fixed to the fixing means.

Here, the second fixing means is configured to use an adhesive means or a locking means. A paper tube is used as the core tube material.

[0010]

According to the above construction, after the cleaning sheet is first fed as the supply roll, the fixing means for fixing the core tube material and the cleaning sheet are peeled off. Then, after separating the core tube material and the cleaning sheet, the core tube material is again mounted on the printing cylinder cleaning device as a take-up tube. Since the second fixing means using the adhering means or the locking means is provided on the surface of the core tube material used as the take-up tube here, the cleaning sheet fed from the new roll can be easily attached to the core tube material. Can be fixed to. That is, if the adhesive means is used as the second fixing means, the core tube material can be fixed to the cleaning sheet only by pressing the tip of the cleaning sheet against the adhesive means, and if the locking means is used as the second fixing means. The core tube material can be fixed to the cleaning sheet by hooking the tip of the cleaning sheet on the protruding portion forming the locking means. As described above, since the tip of the cleaning sheet can be easily attached to the core tube material, the cleaning sheet roll replacement efficiency is improved, and the replacement work time can be shortened.

Further, since the core tube is provided with the second fixing means in advance, when the cleaning sheet is attached to the core tube, the cleaning sheet is positioned on the core tube and the tape and the cleaning sheet are fixed simultaneously. There is no need to do it. For this reason, the relative position of the core tube material and the cleaning sheet does not change during the mounting operation, and when the used cleaning sheet is wound up, winding disorder can be prevented.

Further, since the core tube material of the cleaning sheet roll is used for the winding tube, it is possible to eliminate the conventional work such as unwinding the cleaning sheet after cleaning from the winding tube, and with the core tube material. It becomes possible to discard the cleaning sheet. This also makes it possible to reduce the work time. Further, it is possible to prevent paper dust or printing ink from scattering or adhering, which is generated during unwinding work, etc., and to improve the working environment.

Further, since the core tube material of the cleaning sheet roll is used for the winding tube and the cleaning sheet can be easily attached by the second fixing means, the expensive metal shaft for winding conventionally used. There is no need to use.

Further, if a paper tube is applied to the core tube material, it is not necessary to provide special processing equipment when discarding the cleaning sheet together with the core tube material. Therefore, the discard can be easily performed.

When the locking means is used as the second fixing means, the protrusion is formed on the surface of the core tube material. The protrusions increase the friction coefficient of the surface of the core tube material and fix the cleaning sheet to the core tube material. Specifically, the core tube material surface is subjected to a cutting process or a cut-and-raising process to form a protrusion, or a wrap subjected to unevenness treatment is adhered and fixed to the core tube material surface, or a press-fitting hole is provided on the core tube material surface. It is conceivable to insert a pin into the press-fitting hole to form a protrusion on the surface of the core tube material.

Further, in this embodiment, the paper tube 42 is used as the core tube material.
However, like the paper tube 42, a tube made of a disposable material may be used as the core tube material. For example, if a plastic material is used as the material of the core tube material, the protrusions on the surface of the core tube material can be simultaneously molded when molding the core tube material. For this reason, the post-work for providing the protrusions on the core tube material is abolished, and it is possible to reduce the manufacturing cost.

[0030]

The pipe material is used as the winding pipe of the cylinder cleaning device for the printing press, and the tip of the cleaning sheet fed from the new supply roll can be fixed to the second fixing means.
As a result, the tip of the cleaning sheet fed from the new roll can be easily fixed, and the replacement work time of the cleaning sheet roll can be shortened.

Further, since the core tube material is provided with the second fixing means in advance, when the cleaning sheet is attached to the winding tube,
There is no need to perform the simultaneous work of positioning the cleaning sheet on the winding metal shaft and fixing the cleaning sheet with tape. For this reason, the relative positions of the two in the mounting operation are stable, and it is possible to prevent the used cleaning sheet from being disturbed.

After the used cleaning sheet has been wound up, it is not necessary to unwind the cleaning sheet from the core tube material, and it is possible to discard it together with the core tube material. Therefore, the time required for winding and unwinding can be eliminated, the efficiency of the cleaning work can be improved, and a comfortable working environment can be provided. Further, it is not necessary to use the expensive metal shaft for winding, which has been conventionally used, in the cleaning device.

Further, if a paper tube is applied to the core tube material, it is not necessary to provide special processing equipment when discarding the cleaning sheet together with the core tube material. Therefore, the discard can be easily performed.
