Description

Cylinder cleaning device

The present invention relates to a cylinder cleaning device for cleaning the surface of a cylinder used in a printing machine, and in particular, a cylinder cleaning device of a type that cleans the surface of a cylinder by pressing a cleaning fabric against the surface of the cylinder with a pressing pad. About.

Printing machines used in newspaper printing and commercial printing have many cylinders. The surface of the cylinder often needs to be cleaned to remove excess ink or to remove dirt such as paper dust.

¡Cylinder cleaning equipment is used to clean the cylinder surface. The cylinder cleaning device is used in a state of being incorporated in a printing machine as a component of the printing machine. Several types of cylinder cleaning devices are known. The most typical structure of the cylinder cleaning apparatus is a system using a cleaning fabric. A cylinder cleaning apparatus using a cleaning fabric is pressed against the surface of a rotating cylinder by a pressing pad and wipes the surface of the cylinder with the cleaning fabric. FIG. 18 is an explanatory diagram of a configuration of a conventional cleaning fabric type cylinder cleaning apparatus.

The cylinder cleaning device 1 is disposed so as to face the cylinder 100 to be cleaned.

4 is a cleaning fabric. The cleaning fabric 4 is supplied from the supply roll 2, passes through the pressing pad 10, and is wound up by the winding unit 5. The solenoid 8 presses or releases the pressing pad 10 against the cylinder 100. The cleaning fabric 4 comes into contact with the outer periphery of the cylinder 100 or moves away from the outer periphery of the cylinder 100 as the pressing pad 10 moves forward and backward.

The pressing pad 10 is made of an elastic material such as nitrile rubber. The pressing pad 10 has

thick portions

10b and 10c formed at both ends. 11 and 12 are clamp bars. The

clamp bars

11 and 12 are provided with

clamp grooves

11a and 12a. The clamp grooves 11a and 12a attach and fix the

thick portions

10b and 10c of the pressing pad 10 respectively. When the pressing pad 10 is fixed to the

clamp bars

11 and 12, a pressing portion 10 a is formed. The pressing portion 10a has a substantially semicylindrical shape, that is, a substantially semicylindrical shape.

When the radius of the substantially semi-cylindrical shape of the pressing portion 10a changes, the contact area between the cleaning fabric 4 and the cylinder 100 changes. The contact area between the cleaning fabric 4 and the cylinder 100 is narrowed when the radius of the pressing portion 10a is small, and widened when the radius is large. The radius of the pressing portion 10a needs to be a predetermined size.

On the other hand, the space for installing the cylinder cleaning device 1 near the cylinder 100 to be cleaned is becoming narrower with the recent miniaturization and higher density of the printing press. For example, the cylinder 100 to be cleaned may exist in the back of the gap between other

adjacent cylinders

101 and 102. In the conventional structure, it is difficult to realize the cleaning device 1 that cleans the cylinder 100 by passing between the

cylinders

101 and 102 while maintaining an appropriate radius of the pressing portion 10a.

Patent Document 1 shows a conventional connecting structure of a pressing pad and a clamp bar. Patent Document 2 shows a more detailed structure of a cylinder cleaning device using the same technique as that of the cleaning device 1 shown in FIG. In Patent Document 3, as in Patent Document 1, another example of a coupling structure of a pressing pad and a clamp bar is shown. In the cylinder cleaning apparatus disclosed in Patent Document 1, Patent Document 2, and Patent Document 3, the coupling portion between the pressing pad and the clamp bar protrudes from the outer peripheral surface of the pressing portion having a substantially semicylindrical shape. For this reason, the outer dimension of the pressing pad portion becomes large and cannot be installed in a narrow place.

Patent Document 4 discloses a cylinder cleaning device that can be used in a narrow space compared to other documents. In the cylinder cleaning device, a large peeling force is applied to the pressing pad when the pressing portion of the pressing pad is in contact with the outer periphery of the cylinder. The pressing pad fixing structure disclosed in Patent Document 4 cannot withstand a large peeling force.

The present invention is to realize a cylinder cleaning apparatus having a structure suitable for downsizing and slimming.

In the cylinder cleaning apparatus for cleaning the cylinder outer peripheral surface by pressing the cleaning fabric against the cylinder outer peripheral surface, the present invention comprises a pressing portion that contacts the back surface of the cleaning fabric and thick portions at both ends of the pressing portion. A support bar provided with a pressing pad formed of an elastic material so that the pressing part and the thick part are integrated, and a mounting part for mounting the thick part of the pressing pad on both sides along the longitudinal direction And a side plate disposed outside the thick portion of the pressing pad, and the support pad to which the pressing pad and the pressing pad are attached is sandwiched and held between the side plates on both sides. The cylinder cleaning device is characterized by the above.

Furthermore, the present invention includes the following configurations.

(1) The pressing pad is formed in a flat plate shape, and when the pressing pad is attached to the support bar, the pressing portion becomes a substantially semi-cylindrical shape by bending so that the thick portions of the pressing pad face each other, The thick part of the pressing pad is mounted on the mounting part of the support bar.

(2) The pressing pad is formed so that the pressing portion is semi-cylindrical and the thick portions are opposed to each other, and the thick portion of the pressing pad is mounted on the mounting portion of the support bar.

(3) The side plate is integrally formed on both sides so that one has an opening, and the pressing pad and the support bar are accommodated in the opening.

(4) The side plate sandwiches the pressing pad and the support bar from both sides.

It can also be said that the cylinder cleaning apparatus of the present invention is configured as follows.

First, the pressing pad has a pressing part, a pair of thick parts, and a pair of connecting parts, the pressing part is formed at the center part of the pressing pad, the thick parts are formed at both ends of the pressing pad, and the connecting part is pressed. Formed between the thick part and the thick part. The connecting part is for connecting the pressing part and the thick part, and has a thickness smaller than that of the thick part. And a press part, a thick part, and a connection part are integrally molded with an elastic material.

Next, the support bar has a base portion and a pair of mounting portions, and the base portion extends in the longitudinal direction of the support bar. The mounting portion is continuous with both side surfaces of the base portion, extends in the longitudinal direction, and is recessed by the thickness of the thick portion and the connecting portion from both side surfaces of the base portion. Therefore, the thick portion and the connecting portion can be fitted into the mounting portion, and when fitted, the outer surfaces of the thick portion and the connecting portion are arranged on the same plane as both side surfaces of the base portion.

Further, the side plate is engaged with both side surfaces of the base portion, the thick portion, and the outer surface of the connecting portion, the fixing means is combined therewith, and the side plate is fixed to the base portion.

It is preferable that the thick part has a shape protruding toward the mounting part by a thickness difference from the inner part of the connecting part.

According to the present invention, the thick part of the pressing pad is mounted on the support bar and is sandwiched by the side plates from both sides. For this reason, the thick portion of the pressing pad and the support bar combined with the thick portion do not protrude from the outer peripheral surface of the pressing pad that is substantially semi-cylindrical. Therefore, a cylinder cleaning device suitable for downsizing and slimming can be realized.

Also, when the pressing pad is pressed against the outer periphery of the cylinder together with the cleaning fabric, a strong peeling force acts on the pressing pad. However, the peeling force applied to the pressing pad is distributed and applied to the side plate. Therefore, the side plate can reliably maintain a state where the pressing pad and the support bar are combined even if the plate thickness is thin. The side plate can be selected to have the minimum necessary thickness. Therefore, a cylinder cleaning device suitable for further downsizing and slimming can be realized.

thick portions

10b and 10c, and have a smaller thickness than the

thick portions

10b and 10c. And the press part 10a, the

thick parts

10b and 10c, and the

connection parts

10d and 10e are integrally molded with the elastic material. Further, in this embodiment, the support portion 10f is interposed between the pressing portion 10a and the connecting

thick portions

10b and 10c are connected by the connecting

portions

10d and 10e and the support portion 10f. The support portion 10f is a portion that is between the pressing portion 10a and the

thick portions

10b and 10c and supports the pressing portion 10a with an elastic force with respect to the

thick portions

10b and 10c.

40 is a support bar. The support bar 40 is provided with mounting

portions

42 and 43. The mounting

portions

42 and 43 can be mounted by accommodating the

thick portions

10 b and 10 c of the pressing pad 10. Reference numeral 50 denotes a side plate. The side plate 50 is on both outer sides of the

thick portions

10b and 10c and the connecting

portions

10d and 10e of the pressing pad 10, and accommodates the

thick portions

10b and 10c, the connecting

portions

10d and 10e of the pressing pad 10, and the support bar 40. To do. In the support bar 40, both side surfaces 46 and 47 of the base portion are parallel surfaces. Therefore, the side surfaces 46 and 47 are in close contact with the inner surface of the side plate 50.

8 is a solenoid. The piston rod 81 of the solenoid 8 is linked to the support bar 40. The cleaning fabric 4 is disposed between the pressing pad 10 and the cylinder 100. When the solenoid 8 operates, the pressing pad 10 moves back and forth with respect to the cylinder 100. As a result, the cleaning fabric 4 is pressed by the pressing portion 10a of the pressing pad 10 as necessary, and wipes the surface of the cylinder 100.

As shown in FIG. 1, the pressing pad 10 is attached to the support bar 40 and is sandwiched between the side plates 50 from the outside. Then, the pressing pad 10 has a shape in which the portion of the pressing portion 10a is bent into a substantially semicylindrical shape. The outer periphery of the substantially semi-cylindrical shape is inside the outer surface of the side plate 50.

FIG. 2 is an enlarged cross-sectional view of the support bar 40.

Reference numerals

42 and 43 denote mounting parts. The mounting

portions

42 and 43 have shapes that can accommodate the

thick portions

10b and 10c of the pressing pad 10. Reference numeral 44 denotes a pressing pad shape maintaining wall. The pressing pad shape maintaining wall 44 is provided adjacent to the mounting

portions

42 and 43 shown in FIG. The pressing pad shape maintaining wall 44 has a shape corresponding to the shape of the pressing pad 10 when the

thick portions

10 b and 10 c of the pressing pad 10 are mounted on the mounting

portions

42 and 43. 41 is a base part of the support bar 40. When the pressing pad 10 is attached to the support bar 40, the outer surface of the base 41 and the outer peripheral surface of the pressing pad 10 form substantially the same plane as shown in FIG. Accordingly, the mounting portions for the connecting

portions

10d and 10e are formed by the shape maintaining wall 44, and the

thick portions

10b and 10c and the connecting

portions

10d and 10e can be fitted into the mounting

portions

42, 43, and 44 for mounting. . When fitted, the outer surfaces of the

thick portions

10 b and 10 c and the connecting

portions

10 d and 10 e are arranged on the same plane as the both side surfaces 46 of the base 41.

Here, the connecting

portions

10d and 10e are portions that are sandwiched between the side plate 50 and the support bar 40 and reach the

thick portions

10b and 10c. The thickness may be uniform or may be increased in the vicinity of the

thick portions

10b and 10c, but as described above, it is smaller than the

thick portions

10b and 10. The support portion 10f is a portion between the pressing portion 10a and the connecting

portions

10d and 10e, and is a portion that is not sandwiched between the side plate 50 and the support bar 40.

The

thick portions

10a and 10b are shaped to protrude toward the mounting

portions

42 and 43 by a difference in thickness from the inner surfaces of the connecting

portions

10d and 10e with respect to the connecting

portions

10d and 10e. When the thickness of the connecting

portions

10d and 10e increases in the vicinity of the

thick portions

10b and 10c, the thickness increasing portion is directed toward the mounting portion 44 by a difference in thickness from the other portions rather than the inner surface of the other portions. It is a raised shape.

In FIG. 1, when the pressing pad 10 presses the cleaning fabric 4 against the cylinder 100, a peeling force acts on the pressing pad 10. This is because the frictional force between the cleaning fabric 4 and the cylinder 100 is large. The peeling force acting on the pressing pad 10 acts to pull out the pressing pad 10 from the support bar 40. As a result, the peeling force works to push the side plate 50 outward. However, the peeling force applied to the pressing pad 10 is also distributed to the support bar 40. The side plate 50 only needs to be strong enough to prevent the pressing pad 10 from popping out of the support bar 40 when a peeling force acts on the pressing pad 10. The side plate 50 can be realized by sheet metal or the like.

45 is a through hole provided in the base 41 of the support bar 40. As shown in FIG. 1, the side plate 50 has a cross-sectional shape similar to the English letter U, one of which is an opening. The side plate 50 can be accommodated with the pressing pad 10 mounted on the support bar 40. Reference numeral 60 denotes a fixing screw. The side plate 50 is provided with a hole (not shown) that coincides with the through hole 45 of the support bar 40 when the support bar 40 is accommodated. The fixing screw 60 fixes the support bar 40, the pressing pad 10 attached to the support bar 40, and the side plate 50. The base 41 or the side plate 50 of the support bar 40 has a connection structure for connecting the piston rod 81 (not shown).

FIG. 3 shows a first embodiment of the pressing pad 10 and a flat molding pressing pad 10. The entire pressing pad 10 is formed of an elastic body such as rubber. The flat-molded pressing pad 10 is in a naturally left state before being attached to the support bar 40, and the pressing portion 10a is substantially flat. When the flat-molded pressing pad 10 is attached to the support bar 40, the pressing portion 10a has a substantially semi-cylindrical shape. Since the flat-shaped pressing pad 10 is attached to the support bar 40 by being bent, there is an advantage that the radius of the pressing portion 10a can be made relatively freely according to the dimensions of the support bar 40.

FIG. 4 shows a second form relating to the pressing pad 10, which is a substantially semi-formed pressing pad 10. In the pressing pad 10 shown in FIG. 4, the portion of the pressing portion 10 a is already formed into a substantially semi-cylindrical shape before being attached to the support bar 40. The substantially semi-cylindrical press pad 10 has an advantage that it can be easily assembled to the support bar 40.

FIG. 5 shows a first form relating to the side plate 50. The side plate 50 shown in FIG. 5 has a shape similar to an English letter and is formed integrally with both sides. An opening is formed in one side plate 50. From the opening, the support bar 40 and the pressing pad 10 attached to the support bar 40 are accommodated. The outside of the

thick portions

10b and 10c of the pressing pad 10 and the base portion 41 of the support bar 40 are substantially the same surface. Therefore, the side plate 50 can easily accommodate the support bar 40 and the pressing pad 10 attached to the support bar 40.

FIG. 6 shows a second embodiment relating to the side plate 50 shown in FIG. The side plate 50 shown in FIG. 6 includes a first side plate 501 and a second side plate 502. If the side plate is divided into the first side plate 501 and the second side plate 502, there is an advantage that the dimensions of the support bar 40 can be freely selected without changing the side plate.

The side plate 50 shown in FIGS. 5 and 6 is attached so as to sandwich the base portion 41 of the support bar 40 from both sides, and the

thick portions

10b and 10c of the pressing pad 10 are attached to the mounting

portions

42 and 43 of the support bar 40 and It is sandwiched between the side plates 50 and fixed. The side plate 50 is attached so that the base 41 of the support bar 40 is sandwiched from both sides, and the

thick portions

10b and 10c of the pressing pad 10 are attached to the mounting

portions

42 and 43 of the support bar 40 and the side plate. 50 and fixed.

7, 8, 9, and 10 are process explanatory views showing a process of combining the flat-shaped pressing pad 10 as shown in FIG. 3 with the support bar 40 and the side plate 50. 7 and 8 are explanatory diagrams illustrating the combination of the pressing pad 10 and the support bar 40. FIG. As shown in FIGS. 7 and 8, the thick portion 10 b of the pressing pad 10 fits in the mounting portion 42 of the support bar 40, and the thick portion 10 c fits in the mounting portion 43. Then, the portion 10g combined with the side plate 50 on the outer surface of the base 41 and the outer surface of the pressing pad 10 forms substantially the same surface. FIG. 9 is an explanatory diagram of a combination of the support bar 40 to which the side plate 50 and the pressing pad 10 are attached. As shown in FIG. 9, the side plate 50 accommodates the support bar 40 to which the pressing pad 10 is attached.

11 and 12 are process explanatory views showing a process of combining the pressing pad 10 formed into a substantially semi-cylindrical shape from the beginning shown in FIG. As shown in FIG. 11, in order to combine the pressing pad 10 and the support bar 40, the support portions 10 f and the

thick portions

10 b and 10 c on both sides of the pressing pad 10 are somewhat widened and attached to the support bar 40. This operation is easy and can be completed in a short time. FIG. 12 shows the state of the pressure pad 10 and the support bar 40 after combination. If the pressing pad 10 is formed in a substantially semi-cylindrical shape, the state combined with the support bar 40 can be naturally maintained. Therefore, the combination with the side plate 50 is also easy.

In FIG. 10, 51 is a hole provided in the side plate 50. The hole 51 coincides with the through hole 45 of the support bar 40 when the side plate 50 accommodates the support bar 40. In FIG. 10, 60 is a fixing screw and 61 is a nut. The fixing screw 60 and the nut 61 are fixed with the side plate 50 and the support bar 40 interposed therebetween. The means for connecting and fixing the side plate 50 and the support bar 40 may be fixed by an adhesive in addition to the fixing screw 60. However, since the pressing pad 10 needs to be replaced from time to time, a connecting and fixing means such as a screw 60 and a nut 61 is desirable when the pressing pad 10 can be removed.

FIG. 13 shows a third form of the pressing pad 10. In the pressing pad 10 shown in FIG. 13, the cross sections of the

thick portions

10b and 10c are substantially cylindrical. This is effective when the pressing pad 10 is fixed to the support bar 40 and the side plate 50 by actively utilizing the elasticity of the pressing pad 10. That is, the diameters of the

thick portions

10 b and 10 c that are substantially cylindrical of the pressing pad 10 are made somewhat larger than the mounting

portions

42 and 43 of the support bar 40. Then, when the

thick portions

10 b and 10 c are attached to the support bar 40 and fixed by the side plate 50, they are in close contact with the inner walls of the

attachment portions

42 and 43 while being elastically deformed.

FIG. 14 shows a fourth form of the pressing pad 10. A pipe 13 is formed inside the pressing portion 10 a of the pressing pad 10 along the longitudinal direction of the pressing pad 10. Reference numeral 14 denotes a nozzle hole. A plurality of nozzle holes 14 are provided at predetermined intervals. When the cleaning liquid is supplied to the pipe 13, the cleaning liquid is sprayed from the nozzle hole 14. If it does so, a washing | cleaning liquid can be supplied to the washing | cleaning fabric which is contacting the press part 10a.

FIG. 15 shows a fifth form of the pressing pad 10. The pressing pad 10 differs in the thickness of the support part 10f and the pressing part 10a. Compared to the thickness of the support portion 10f, the pressing portion 10a is thicker. That is, the thickness of the portion of the pressing portion 10a is thicker than that of the thinnest portion between the pressing portion 10a and the

thick portions

10b and 10c of the pressing pad 10. Therefore, compared with the example shown in FIG. 1, the pressing portion 10 a is hard to be deformed, and thus makes a hard contact with the cylinder 100.

FIG. 16 shows a sixth form of the pressing pad 10. In the pressing pad 10 shown in FIG. 16, the thickness of the supporting portion 10f and the pressing portion 10a is different. The portion of the pressing portion 10a is lighter than the thickness of the portion of the supporting portion 10f. That is, in the pressing pad 10, the thickness of the pressing portion 10 a is thinner than the thickness of the portion sandwiched between the support bar 40 and the side plate 50. If the thickness of the pressing portion 10a of the pressing pad 10 is thin, the pressing pad 10 is easily deformed when contacting the cylinder 100. Therefore, as compared with the example shown in FIG. 1, the pressing portion 10 a softly contacts the cylinder 100.

The thickness of the pressing portion 10a is related to the time required for cleaning the cylinder cleaning device 1 and the consumption of cleaning fabric required for cleaning, but the optimal thickness should be determined by experiment.

FIG. 17 shows a seventh embodiment of the pressing pad 10. As for the press pad 10, the press part 10 and the

thick parts

10b and 10c are integrally formed. The press pad 10 does not need to be the same material as a whole. In the example shown in FIG. 17, the pressing pad 10 is composed of two materials, a material 10h and a material 10k. When two or more materials are combined, there is an advantage that a material suitable for the pressing portion 10a and a material suitable for the

thick portions

10b and 10c can be individually selected. For example, if necessary, a soft material having a low hardness can be used as the material 10h in the portion including the pressing portion 10a, and a hard material having a high hardness can be selected as the material 10k in the portion including the support portion 10f. If it does so, a flexible press state is realizable, without reducing the thickness of press part 10a. Further, although not shown, two or more materials may be combined in the thickness direction of the pressing pad 10. Then, characteristics such as elasticity that cannot be obtained with one material can be realized.
