Description

The present invention relates to a blanket cleaning cloth winding / reproducing apparatus for a printing press, and more particularly to a winding / reproducing technique for winding a used blanket cleaning cloth so that it can be reused in offset printing.

Offset printing, which is the mainstream of current color printing, is an image area (printed area) that is compatible with oil-based ink on the surface of the plate cylinder, and a non-image area that is easily absorbed by water and does not have oil-based ink. The surface of the rubber blanket cylinder that is easy to be familiar with the oil-based ink. Is a printing method in which the blanket cylinder surface is pressed against printing paper and printed (normal image).

By the way, in an offset printing machine that performs such offset printing, ink or paper dust of printing paper accumulates on the blanket cylinder surface by a long-time printing operation, and it becomes impossible to obtain a clear image line, The deposit on the blanket cylinder surface needs to be cleaned (blanket cleaning). Such blanket cleaning is also performed when changing the content to be printed.

Blanket cleaning is performed by a cleaning unit incorporated in the offset printing press. In this cleaning unit, a cleaning cloth roll in which a blanket cleaning cloth is wound around a paper tube and a metal winding core that winds up and collects the used blanket cleaning cloth can be removed in parallel at a predetermined interval. And a cleaning liquid supply means for supplying and supplying a cleaning liquid to the blanket cleaning cloth and a pressing means for pressing the blanket cleaning cloth against the blanket cylinder surface between the cleaning cloth roll and the winding core rod. Is provided. A nonwoven fabric is used as the blanket cleaning cloth.

The blanket cleaning cloth fed out from the cleaning cloth roll is pressed against and contacts the rotating blanket cylinder surface by the pressing means while the cleaning liquid is sprayed by the cleaning liquid supply means, and the deposit on the blanket cylinder surface is removed. Clean the blanket cylinder surface while wiping. The blanket cleaning cloth that has been used after the cleaning of the blanket surface is wound around the winding core and collected.

When all of the blanket cleaning cloth of the cleaning cloth roll has been used and wound up and collected on the winding core rod, the paper tube of the cleaning cloth roll from which all of the blanket cleaning cloth has been unwound and used The above-described winding core rods that have wound and collected the used blanket cleaning cloth are each removed from the above-mentioned cleaning unit. And since the paper tube is made of paper and inexpensive, it is disposed of as it is. However, since the winding core rod is made of metal and expensive, only the used blanket cleaning cloth that has been wound up is rewound and discarded. At the same time, the take-up core rod is mounted on the cleaning unit again and used repeatedly.

However, such conventional blanket cleaning has various problems as listed below, and there has been a strong demand for improvement.

(1) As described above, the blanket cleaning cloth is disposed of after a single use, but the non-woven fabric itself, which is a constituent material thereof, is relatively high, and the material cost and the cleaning cloth roll, which is a product, are also relatively expensive. As a result, running costs were high and very uneconomical.

(2) The used blanket cleaning cloth cannot be disposed of as ordinary general waste, but is disposed of as an industrial waste, and this is also uneconomical.

  In other words, the used blanket cleaning cloth needs to be incinerated as industrial waste, and is discarded for a fee. Moreover, in order to incinerate, it is necessary to cut the blanket cleaning cloth to a size equal to or less than a predetermined shape, which causes a problem that the cost is higher than industrial waste that can be incinerated as it is.

(3) As described above, the take-up core rod that has been wound up and collected from the used blanket cleaning cloth will rewind the used blanket washing cloth once taken up and collected for repeated use. This unwinding operation has been performed manually by hand. Since the winding length of the blanket cleaning cloth is as long as 15 m or more, it takes a lot of work and the used blanket has been unwound. The cleaning cloth was very bulky and inconvenient to handle.

  In this regard, a cleaning cloth cleaning device as disclosed in Patent Document 1 has been developed.

  This cleaning cloth cleaning device can be reused by cleaning the front and back surfaces of the used blanket cleaning cloth. As shown in FIG. 13, a feeding section b for feeding the used blanket W to the apparatus main body a A winding portion c for winding the used blanket W is provided at a predetermined distance. A used cleaning cloth roll d obtained by winding and recovering a used blanket cleaning cloth W on the winding core bar is rotatably supported on the feeding portion b so that the cleaning cloth roll d is used. The leading end portion of the cloth W is guided to the winding portion c via the guide rollers e and e, and is connected and fixed to the winding core f of the winding portion c by tape.

  Further, a pair of upper and lower rotating brushes g and g for scraping and removing deposits such as ink deposited on the front and back surfaces of the used blanket cleaning cloth W are provided between the feeding portion b and the winding portion c. Along with the front and rear positions of these rotary brushes g, g (that is, the upstream and downstream sides in the winding direction of the blanket cleaning cloth), the air knife h that injects air and the rotary brushes g, g were scraped. Each of the vacuum ducts i for sucking the deposits is arranged to be open, and a vibrator j for vibrating the used blanket cleaning cloth W in the vertical direction is provided on the downstream side of the vacuum duct i.

When the cleaning cloth cleaning device is activated, the feeding part b and the winding part c are operated to start winding the used blanket cleaning cloth W from the feeding part b to the winding part c. The rotating brushes g and g, the air knife h, the vacuum duct i, and the vibrator j are activated. As a result, the used blanket cleaning cloth W fed out from the feeding section b is scraped and removed while the deposits on both the front and back surfaces are scraped and removed by the up-and-down rotating brushes g and g, the jet air of the air knife h and the vibrator j. Then, the blown-up deposit is sucked and collected by the vacuum duct i. The blanket cleaning cloth W that has been cleaned in this manner and wound on the winding core f of the winding section c is again attached to the cleaning unit of the offset printing machine and reused.

However, the feeding part b, the winding part c, the rotating brush g, the air knife h, the vacuum duct i, and the vibrator j, which are constituent parts of the cleaning cloth cleaning device, are configured by using independent drive sources. Is complicated and large-sized, and the cost of the apparatus is very high, and even if it is reused, it can only be reused a few times due to the nature of the blanket cleaning cloth W, From the viewpoint of reducing running costs, which is the purpose of reuse, the actual situation is that almost no effect can be expected.

The brake is rotated. Further, by rotating the turnbuckle 24, the tension of the friction belt 23 can be appropriately adjusted to an optimum value.

C. Cleaning cloth winding part 2:
The cleaning cloth take-up unit 2 is a part that functions as a cleaning cloth take-up means for rotatively supporting the take-up core 30 that takes up the blanket cleaning cloth W fed from the cleaning cloth feed unit 1 so as to be removable. As the paper tube 30, the paper tube around which the blanket cleaning cloth W before use is wound is preferably used, but other tube bodies having the same structure may be used. The end portion structure of the winding core 30 is the same as the end portion structure of the winding core rod 10 shown in FIGS. 7 (a) and 7 (b).

As shown in FIGS. 3 and 4, the cleaning cloth winding unit 2 of the illustrated embodiment includes a pair of rotation support units 31 and 32 that support and rotate both ends of the winding core 30, and supports both of these rotations. The portions 31 and 32 are fixedly provided at both longitudinal ends of the upper surface of the support base 6.

The pair of rotation support portions 31 and 32 have the same basic structure, and, like the rotation support portions 11 and 12 of the cleaning cloth feeding portion 1, specifically, as shown in FIG. ) 33 is rotatably supported by a pair of bearing portions 34, 34, and a support socket 35 for fitting and supporting one end of the take-up core 30 is provided at the tip thereof.

The specific structures of the constituent members 33, 34, and 35 of the rotary support portions 31 and 32 are the same as the constituent members 13, 14, and 15 of the rotary support portions 11 and 12 of the cleaning cloth feeding portion 1, respectively. The attachment / detachment procedure of the take-up core 30 with respect to the rotation support portions 31 and 32 is exactly the same as that of the take-up core rod 10 described above.

Then, with respect to the take-up core 30 that is rotatably supported by the cleaning cloth take-up unit 2 in this way, the leading end portion of the blanket cleaning cloth W that is fed from the take-up core 10 that is rotatably supported by the cleaning cloth feed unit 1 is In this case, the blanket cleaning cloth W fed out from the winding core 10 of the cleaning cloth feeding section 1 winds up its feeding surface, that is, the used surface Wa, as shown in FIG. It is wound and connected so as to be wound around the outer periphery of the winding core 30 of the cleaning cloth winding unit 2 so as to be the back surface.

By adopting such a winding method, the blanket cleaning cloth W fed out from the winding core 10 is reversed and wound around the winding core 30, and thus the winding core 30 is washed with the blanket. By attaching the cleaning cloth rolls 30 and W formed by winding the cloth W to a cleaning unit incorporated in an offset printing machine (not shown), the winding surface Wb is used as a new cleaning surface. become.

D. Rotation drive structure of cleaning cloth feeding unit 1 and cleaning cloth winding unit 2:
As described above, the rotational drive source of the cleaning cloth take-up unit 2 is the drive motor 20 shared with the rotational driving source of the cleaning cloth supply unit 1, and the rotational drive structure of these parts 1 and 2 is as follows. It is configured.

That is, as shown in FIG. 2 and FIG. 3, the drive motor 20 that is a rotational drive source is provided horizontally at the intermediate portion in the vertical direction of the apparatus base 7, and the rotary shaft 20a is connected via a power transmission mechanism. The cleaning cloth feeding unit 1 and the cleaning cloth winding unit 2 are drivingly connected. As the drive motor 20, a geared motor is used, and the drive is controlled by a motor operation panel 40 installed on the side surface of the apparatus body 5. The motor operation panel 40 is provided with a power switch 40a for turning the power on and off, and a rotary speed adjustment dial 40b for an inverter (not shown) for continuously controlling the rotational speed of the drive motor 20.

Specifically, as shown in FIGS. 2 to 4, the power transmission mechanism includes a timing pulley 41 a attached and fixed to the rotary shaft 20 a of the drive motor 20, and a drive-side rotation support portion of the cleaning cloth winding unit 2. A power transmission belt mechanism 41 including a timing pulley 41b attached to and fixed to a rotating shaft 33 of the motor 31 and a timing belt 41c wound around both the pulleys 41a and 41b, and a winding target of the present winding / reproducing device, The used blanket cleaning cloth W wound around the winding core 30 rotatably supported by the cleaning cloth winding section 2 from the winding core rod 10 rotatably supported by the cleaning cloth feeding section 1, and the cleaning cloth feeding The friction brake mechanism 21 is provided on the rotation shaft 13 of the drive side rotation support portion 11 of the portion 1.

When the drive motor 20 is rotationally driven, the rotational support shafts 33 and 33 of the cleaning cloth winding unit 2 and the rotational support shafts 33 and 33 are rotatably supported via the power transmission belt mechanism 41 (41a to 41c). When the wound take-up core 30 is taken up and rotated, the winding supported by the rotary support shafts 13 and 13 of the wash cloth feeding portion 1 is supported by the tensile force of the blanket wash cloth W taken up by the take-up core 30. The rotation support shafts 13 and 13 are fed and rotated through the core rod 10. In this case, the braking action of the friction brake mechanism 21 provided on the rotation support shaft 13 on the drive side of the cleaning cloth feeding portion 1 prevents the increase of the rotation speed due to the inertia of the winding core rod 10, and the winding core. The rod 10 is fed out and rotated while maintaining an appropriate rotational speed corresponding to the rotational speed of the winding core 30, that is, the rotational speed of the drive motor 20.

E. Tension applying unit 3:
The tension applying unit 3 functions as a tension applying unit that applies a predetermined tension to the blanket cleaning cloth W wound around the cleaning cloth winding unit 2, and specifically includes a tension roller 45.

Specifically, the tension roller 45 is formed of a solid cylindrical metal rod, and between the cleaning cloth feeding unit 1 and the cleaning cloth winding unit 2, the cleaning cloth feeding unit 1 and the cleaning cloth winding. The winding core rod 10 and the winding core 30 that are rotatably supported by the take-up unit 2 are rotatably supported in parallel with and freely rotatable.

In the illustrated embodiment, the pair of rotation support portions 46 and 47 are provided at both ends in the longitudinal direction of the rectangular opening 6a formed at the center portion of the support base 6 of the apparatus body 5 (both left and right ends in FIGS. 3 and 4). The shaft portions 45a and 45b of the tension roller 45 are rotatably supported by the bearing portions 46a and 47a of the pair of rotation support portions 46 and 47, respectively. .

As shown in FIG. 2, the bearing portions 46a and 47a of the both rotation support portions 46 and 47 are in the form of guide grooves extending linearly in the vertical direction from the upper end to the lower portion of the rotation support portion. The roller 45 has both end shaft portions 45a and 45b slidably guided in the vertical direction by the bearing portions 46a and 47a, and can be moved up and down.

The tension roller 45 presses the upper surface of the blanket cleaning cloth W wound around the outer periphery of the winding core 30 from the winding core rod 10 of the cleaning cloth feeding unit 1 from the upper side by its own weight. Thus, during the winding operation of the blanket cleaning cloth W, the tension roller 45 is wound around the winding core 30 from the winding core rod 10 by the cooperative action with the braking action of the friction brake mechanism 21. While applying appropriate tension to the blanket cleaning cloth W, flat and uniform winding onto the winding core 30 with both end faces of the blanket cleaning cloth W aligned is possible.

In relation to this, although not specifically shown, a spiral groove is formed on the outer peripheral surface of the cylinder of the tension roller 45, and during the winding operation of the blanket cleaning cloth W, the rotation guide of the spiral groove is provided. As a result, the blanket cleaning cloth W is stretched to the outside in the width direction to be flattened, and the synergistic effect with the above-described tension application effect effectively prevents the blanket cleaning cloth W from wrinkling and the blanket cleaning. Flat and uniform winding onto the winding core 30 in a state where both end faces of the cloth W are aligned is performed more reliably. The spiral groove formed on the outer peripheral surface of the cylinder of the tension roller 45 is selectively formed according to the purpose, and the specific shape of the spiral groove is also formed on the blanket cleaning cloth W that is rotated and guided by the tension roller 45. On the other hand, the blanket cleaning cloth W is appropriately designed in consideration of the outer diameter size of the tension roller 45, the surface property of the cylindrical outer peripheral surface, and the like so that the stretching action to the outside in the width direction works effectively.

Further, since the bearing portions 46a and 47a of the both rotation support portions 46 and 47 are in the form of guide grooves as described above, both end shaft portions 45a and 45b of the tension roller 45 are connected to the bearing portions 46a and 47a. By moving to the upper end, the tension roller 45 can be removed from both the rotation support portions 6 and 47.

When a used blanket cleaning cloth W, which will be described later, is mounted, the tension roller 45 is temporarily removed from the both rotation support portions 46 and 47 to be fed out from the take-up core 10 of the cleaning cloth feeding portion 1. The operation of winding and connecting the blanket cleaning cloth W around the outer periphery of the winding core 30 can be easily performed.
