SUMMARY OF INVENTION
Technical Problems

However, the intaglio printing press disclosed in Patent Literature 1 has a problem as below. Specifically, the chablon roller is attached and detached every time maintenance, such as cleaning and replacement of the blanket, for the collecting cylinder, is performed. Since the chablon roller is a heavy object (e.g., 300 kg/1 roller), the attachment and detachment have to be performed while the chablon roller is hung by a crane or the like. Moreover, the attachment requires adjustment of the contact pressure against the collecting cylinder. Hence, there is required troublesome and time-consuming work.


In addition, it is a large burden on the operator, and lowers productivity significantly, to attach and detach the chablon roller at occasions other than maintenance of the chablon roller itself, i.e., at every cleaning and replacement of the blanket for the collecting cylinder, which are performed frequently (e.g., the cleaning is once or twice a day and the replacement of the blanket is once a week).


Moreover, a machine structure to allow the chablon roller to be detached from the main frame (main structure) and to be reattached (moved) to the inker frame (inking carriage) is complicated. Hence, there is a problem of causing a cost increase.


To solve these, the present invention has an object to provide an intaglio printing press which allows an access to a collecting cylinder without having to attach and detach a rotating part such as a chablon roller and thus facilitates maintenance work for the collecting cylinder such as cleaning work for the collecting cylinder and replacement work for a blanket.


Solution to Problems

An intaglio printing press according to the present invention for achieving the object described above includes: an intaglio cylinder; a collecting cylinder which has a blanket attached to a circumferential surface of the collecting cylinder, is in contact with the intaglio cylinder, and transfers ink onto the intaglio cylinder; multiple rotating parts which are in contact with the collecting cylinder and transfer ink onto the collecting cylinder; and an ink feeding unit which feeds ink to the rotating parts. The intaglio printing press is characterized in that the multiple rotating parts are arranged in such a manner that a work space is formed between adjacent ones of the rotating parts, the work space allowing an access to the collecting cylinder without detachment of the rotating parts.


Further, the intaglio printing press is characterized by including: a first frame which rotatably supports the collecting cylinder and the rotating parts; and a second frame which supports the ink feeding unit, is supported movably, and allows the ink feeding unit to move in approaching and separating directions with respect to the rotating parts. The access to the collecting cylinder is allowed through the work space from a space formed between the ink feeding unit and the rotating parts.


Further, the intaglio printing press is characterized in that the number of the rotating parts provided is at least five.


Further, the intaglio printing press is characterized in that one of the adjacent rotating parts forming the work space is a rotating part located at the highest position.


Further, the intaglio printing press is characterized in that the rotating parts are arranged in such a manner that an interval between the rotating part located at the highest position and the rotating part immediately below the highest rotating part is larger than an interval between other adjacent ones of the rotating parts.


Further, the intaglio printing press is characterized in that a liftable step is placed in the space.


Further, the intaglio printing press is characterized in that, in the work space, a safety bar is provided which is located near a point where the collecting cylinder and any of the rotating parts is in contact with each other, and which extends in an axial direction of the collecting cylinder.


Further, the intaglio printing press is characterized in that a main-unit inching switch, a main-unit reverse inching switch, and a main-unit adjusting switch are provided on a main-unit frame located at a lateral side of the work space, the main-unit adjusting switch allowing switch operations of the main-unit inching switch and the main-unit reverse inching switch.


Advantageous Effects of Invention

The intaglio printing press according to the present invention allows an access to a collecting cylinder by using a work space formed between two adjacent rotating parts such as chablon rollers, without having to attach and detach the rotating parts at the time of maintenance such as cleaning work for the collecting cylinder or replacement work for a blanket. Hence, the maintenance work for the collecting cylinder can be performed easily.


Thus, the maintenance work takes a shorter period of time, which in turn reduces the load on the operator and suppresses a decrease in productivity. Further, since a simple machine structure can be achieved by changing the arrangement of the rotating parts, a cost reduction is possible.

DESCRIPTION OF EMBODIMENTS

Hereinbelow, an intaglio printing press according to the present invention will be described in detail through examples by using the drawings.


First Example


FIG. 1 is an overall configuration diagram of an intaglio printing press showing a first example of the present invention. FIG. 2 is an enlarged view of a main part of a printing apparatus showing when maintenance is performed on a collecting cylinder. FIG. 3 is a view on an arrow A in FIG. 4 showing a work space. FIG. 4 is a view for explaining the work space and a notched portion of the collecting cylinder.


As shown in FIG. 1, the intaglio printing press is basically formed of: a sheet feeding apparatus 10 that serves as an apparatus for feeding sheet-shaped objects; a printing apparatus 20 that performs intaglio printing on sheet-shaped objects; and a sheet discharging apparatus 40 that serves as an apparatus for discharging sheet-shaped objects.


The sheet feeding apparatus 10, in which sheets W as sheet-shaped objects are piled up, communicates with a feeder board 11 which transports the sheets W fed out individually from the top layer of the pile by a suction mechanism as a feeding mechanism of the sheet feeding apparatus 10. The feeder board 11 is provided with a swing arm shaft pregripper 12 which is held swingably and grips the sheet W on the feeder board 11.


In the printing apparatus 20, the swing arm shaft pregripper 12 communicates, via transfer cylinders 22a and 22b, with an impression cylinder 21 which is what is called a triple-size cylinder on which three grippers (not shown) are arranged at an equal interval in the circumferential direction as holding units to hold the sheet W. The impression cylinder 21 is supported by main frames (first frame) 23. The transfer cylinders 22a and 22b are provided with grippers similar to the grippers of the impression cylinder 21. These grippers enable a gripping change of a gripped sheet W from the swing arm shaft pregripper 12 to the grippers of the impression cylinder 21.


The impression cylinder 21 is in contact with a plate cylinder 24. The plate cylinder 24 is what is called a triple-size cylinder to which three intaglio printing plates can be attached in the circumferential direction, and is supported by the main frames 23. The intaglio printing plates of the plate cylinder 24 are in contact with an ink collecting cylinder (collecting cylinder) 25. The ink collecting cylinder 25 is what is called quadruple-size cylinder to which four rubber blankets 26a to 26d (see FIG. 2) can be attached in the circumferential direction, and is supported by the main frames 23.


The ink collecting cylinder 25 is in contact with five chablon rollers (rotating parts) 27a to 27e arranged in the circumferential direction. The chablon rollers 27a to 27e each have a circumferential-surface length corresponding to the lengths of a blanket of the impression cylinder 21 and the intaglio printing plates of the plate cylinder 24, and are supported by the main frames 23. The chablon rollers 27a to 27e are in contact with inking devices (ink feeding units) 28a to 28e, respectively. The inking devices 28a to 28e feed inks to the chablon rollers 27a to 27e, respectively, and are supported by an inker frame (second frame) 29 (see FIG. 2). The inking devices 28a to 28e are filled with inks of mutually different colors, respectively.


The inker frame 29 is supported movably in an approaching/separating direction (a lateral direction in FIG. 1) with respect to a chablon roller support of each main frame 23. Specifically, the inker frame 29 is supported in such a movable manner that it can move between an ink feeding position (see a solid line position in FIG. 1) and a separated position (see a two-dot chain line position in FIG. 1 and a solid line position in FIG. 2). The ink feeding position is where the inking devices 28a to 28e are in contact with the chablon rollers 27a to 27e and transfer their inks to the chablon rollers 27a to 27e. The separated position is where the inking devices 28a to 28e are separated from the chablon rollers 27a to 27e.


The intaglio printing plates of the plate cylinder 24 are in contact with a wiping roller 30. This wiping roller 30 is soaked in a solvent pooled in a wiping tank 31.


In the sheet discharging apparatus 40, a sheet discharging cylinder 41 is in contact with the impression cylinder 21. A pair of unillustrated sprockets constituting this sheet discharging cylinder 41 have a sheet discharging chain 42 endlessly wound therearound. On a downstream side of the sheet discharging chain 42 in the direction of travel, there is disposed a delivery unit 44 in which three delivery piles 43a to 43c are aligned. Meanwhile, unillustrated gripper units are provided to the sheet discharging chain 42 at a certain interval.


In the first example, a work space Sa is formed between two adjacent ones of the chablon rollers 27a to 27e as shown in FIG. 2. The work space Sa allows an access to the ink collecting cylinder 25 without having to detach the chablon rollers 27a to 27e at the time of maintenance such as cleaning work for the ink collecting cylinder 25 or replacement work for the blankets.


In the illustrated example, the chablon rollers 27a to 27e are arranged in such a manner that the Interval between the chablon roller 27e, which is located at the highest position among the five chablon rollers 27a to 27e, and the chablon roller 27d immediately below the chablon roller 27e is larger than the interval between any other two adjacent chablon rollers. When the inker frame 29 is at the separated position shown in FIG. 2 and an operator M is located in a space Sb formed between the inking devices 28a to 28e and the chablon rollers 27a to 27e, the operator M can access to the ink collecting cylinder 25 through the work space Sa. That is, an access to the ink collecting cylinder 25 is allowed from the space Sb, formed between the inking devices 28a to 28e and the chablon rollers 27a to 27e, and through the work space Sa.


In addition, a liftable (retractable) step 32 is placed in the space Sb. This step 32 is supported movably upward and downward between a stored position (see a chain line position in FIG. 2) and a work position (see a solid line position in FIG. 2). The stored position is where the step 32 is stored in such a manner as not to hinder the movement of the inker frame 29. The work position is where the step 32 is lifted from the stored position and the operator M gets on the step 32 to perform operations. The step 32 is placed at the stored position at the time of printing, whereas the step 32 is placed at the work position at the time of performing maintenance work, such as cleaning work for the ink collecting cylinder 25 or replacement work for the blankets, through the work space Sa. Note that the step 32 is not limited to a liftable (retractable) step as above, and may be one without the lifting function. In that case, the step 32 is moved in and out of the space Sb (the inside of the apparatus).


In a case of replacement work for the blankets of the ink collecting cylinder 25, the work is performed while operating a leading edge winding shaft 34a and a trailing edge winding shaft 34b accommodated in each of four notches (gaps) 33a to 33d formed in an circumferential surface of the ink collecting cylinder 25 at an equal interval as shown in FIGS. 3 and 4.


Specifically, bars 35 attached to both end portions of each of the blankets 26a to 26d are made detachably attachable to blanket holding means 36a and 36b provided in plurality (four in the illustrated example) in the axial direction of the leading edge winding shaft 34a and the trailing edge winding shaft 34b. Both end portions of each of the leading edge winding shaft 34a and the trailing edge winding shaft 34b are rotatably supported between paired right and left bearers 37 of the ink collecting cylinder 25. One end portions of the leading edge winding shaft 34a and the trailing edge winding shaft 34b which protrude outside the bearer 37 are provided with worm gears 38a and 38b, respectively. By operating operation portions 62a and 62b of the respective worm gears 38a and 38b with a tool such as a spanner, the leading edge winding shaft 34a and the trailing edge winding shaft 34b can be rotated in a certain direction (tightening direction or loosening direction).


Note that in FIGS. 3 and 4, 39a and 39b represent supports to rotatably support the leading edge winding shaft 34a and the trailing edge winding shaft 34b at two positions in the longitudinal direction inside the corresponding one of the notches (gaps) 33a to 33d. 53a and 53b represent safety bars which are located near the points where the ink collecting cylinder 25 and the respective chablon rollers 27d and 27e are in contact with each other in the work space Sa. The safety bars 53a and 53b extend in the axial direction of the ink collecting cylinder 25 and lie between the paired right and left main frames 23. The safety bars 53a and 53b are supported slightly movably in a direction perpendicular to the cylinder shafts of the ink collecting cylinder 25 and the chablon rollers 27d and 27e. Upon interference with other objects, the safety bars 53a and 53b move and thereby a signal to stop the rotation of the main unit is transmitted.


Also, in FIGS. 4, 50a and 50b represent some of packing sheets (packing members) provided respectively to the blankets 26a to 26d, specifically, packing sheets that correspond to the blankets 26a and 26b. Bars 51 are attached to the leading edges of the packing sheets 50a to 50d, respectively, and are made detachably attachable to packing sheet holding means 52 in the respective notches (gaps) 33a to 33d. The trailing edges of the packing sheets 50a to 50d are free ends entering the respective gaps 33a to 33d.


As shown in FIG. 3, on a cover 54 attached to the work-side main frame 23, there are provided a main-unit reverse inching switch 55a, a main-unit adjusting switch 55b, and a main-unit inching switch 55c each given a lamp. These switches 55a to 55c are located on a lateral side of the work space Sa and subjected to switch operations at the time of maintenance such as cleaning work for the ink collecting cylinder 25 or replacement work for the blankets.


A switch operation of the main-unit reverse inching switch 55a causes the machine to perform a reverse inching operation (in which each cylinder and the like rotate by a predetermined angle in a direction opposite to the sheet transport direction and stop). A switch operation of the main-unit inching switch 55c causes the machine to perform an inching operation (in which each cylinder and the like rotate by a predetermined angle in the sheet transport direction and stop). A switch operation of the main-unit adjusting switch 55b enables the reverse inching and inching of the machine by the switch operations of the main-unit reverse inching switch 55a and the main-unit inching switch 55c.


In the intaglio printing press as described above, sheets W fed out individually from the sheet feeding apparatus 10 onto the feeder board 11 pass through the swing arm shaft pregripper 12 and the transfer cylinders 22a and 22b. Then, the gripping of the sheet W is changed to the gripping by the grippers of the impression cylinder 21, and thereafter the sheet W is transported. Meanwhile, the inks of the inking devices 28a to 28e are transferred onto the ink collecting cylinder 25 through the chablon rollers 27a to 27e and then fed on surfaces of the intaglio printing plates of the plate cylinder 24. Excess portions of the inks are removed by the wiping roller 30. Then, the sheet W passes between the impression cylinder 21 and the plate cylinder 24 and the inks are hence transferred and printed onto the sheet W. Thereafter, the sheet W is transported by the sheet discharging chain 42 of the sheet discharging apparatus 40 through the sheet discharging cylinder 41 and discharged on a predetermined one of the delivery piles 43a to 43c.


In the first example, at the time of performing maintenance such as cleaning work for the ink collecting cylinder 25 or replacement work for the blankets 26a to 26d on the ink collecting cylinder 25, one can access to the ink collecting cylinder 25 from the work space Sa formed between the chablon roller 27e located at the highest position and the chablon roller 27d immediately below the chablon roller 27e, through the space Sb formed by moving the inker frame 29 backward (by separating the inker frame 29 from the chablon roller support of the main frames 23), without having to attach and detach the chablon rollers 27a to 27e. Accordingly, maintenance work for the ink collecting cylinder 25 can be performed easily.


Specifically, after placing the inker frame 29 at the separated position shown in FIG. 2, the operator M lifts the step 32 in the stored position to the work position. From the top of the step 32, the operator M performs switch operations on switches such as the main-unit reverse inching switch 55a, the main-unit adjusting switch 55b, and/or the main-unit inching switch 55c to perform inching and/or reverse inching of the ink collecting cylinder 25. In this way, the operator M can clean the blankets 26a to 26d on the ink collecting cylinder 25 through the work space Sa. In addition, the operator M can perform replacement work for the blankets 26a to 26d on the ink collecting cylinder 25 through the work space Sa by: the above-described rotating operation of the leading edge winding shaft 34a and the trailing edge winding shaft 34b via the worm gears 38 by operating the operation portions 62a and 62b using a tool such a spanner; attaching and detaching operations of the blankets 26a to 26d by the blanket holding means 36a and 36b with respect to the leading edge winding shaft 34a and the trailing edge winding shaft 34b; and switch operations of the main-unit reverse inching switch 55a, the main-unit adjusting switch 55b, and the main-unit inching switch 55c.


As a result, maintenance work takes a shorter period of time, which in turn reduces the load on the operator. Further, since the downtime of the line is reduced, a decrease in productivity can be suppressed. Furthermore, since a simple machine structure can be achieved by changing the arrangement of the chablon rollers 27a and 27e, a cost reduction is possible.


Also, in the first example, unlike what is disclosed in Patent Literature 1, any of the chablon rollers 27a to 27e does not have to be detached and reattached (moved) to the inker frame 29. This brings about an advantage that when performing maintenance for the above-described ink collecting cylinder 25 for example, the operator M can also perform maintenance for the inking devices 28a to 28e supported by the inker frame 29, by turning around within the space Sb.


In addition, in the first example, the above-described work space Sa is formed between the chablon roller 27e located at the highest position and the chablon roller 27d immediately below the chablon roller 27e. This brings about an advantage that the arrangement (layout) of ink rollers of all the inking devices 28a to 28e on the inker frame 29 can be made the same. Specifically, if the chablon roller 27e located at the highest position and the chablon roller 27d immediately below the chablon roller 27e have a smaller interval therebetween, there occur conflicts with fountains and the like, which in turn requires a large diameter for the ink roller of the inking device 28e that corresponds to the chablon roller 27e located at the highest position, or some other countermeasure. However, as such is not needed in the case of the first example.


Second Example


FIG. 5 is an enlarged view of a main part of a printing apparatus showing a second example of the present invention.


The second example applies the present invention to an intaglio printing press including a triple-size cylinder, which is the ink collecting cylinder 25 of the first example including three gaps 33a to 33c at an equal interval in the circumferential direction. The only difference from the first example in configuration is the diameter ratio of the ink collecting cylinder 25 to the intaglio cylinder 24. The second example is the same as the first example in that the five chablon rollers 27a to 27e are in contact with the ink collecting cylinder 25, and that the work space Sa is formed between the chablon roller 27e, which is located at the highest position among the five chablon rollers 27a to 27e, and the chablon roller 27d immediately below the chablon roller 27e. The second example can also bring about the same advantageous effects as the first example.


Third Example


FIG. 6 is an enlarged view of a main part of a printing apparatus showing a third example of the present invention.


The third example applies the present invention to an intaglio printing press of six colors obtained by adding a chablon roller 27f and an inking device 28f of another color to the chablon rollers 27a to 27e and the inking devices 28a to 28e of the first example. The location of the work space Sa is the same as the first example. The third example can also bring about the same advantageous effects as the first example. Note that in this case, the chablon roller 27f thus added is supported by the main frames 23 similarly to the other chablon rollers 27a to 27e, whereas the inking device 28f is supported by an inker frame 60 which can be drawn laterally (in the lateral direction), i.e., in the axial direction of the ink collecting cylinder 25.



FIG. 7 is an enlarged view of a main part of a printing apparatus showing a fourth example of the present invention.


The fourth example applies the present invention to an intaglio printing press of seven colors obtained by adding chablon rollers 27f and 27g and inking devices 28f and 28g of two other colors to the chablon rollers 27a to 27e and the inking devices 28a to 28e of the first example. The location of the work space Sa is the same as the first example. The fourth example can also bring about the same advantageous effects as the first example. Note that in this case, the chablon rollers 27f and 27g thus added are supported by the main frames 23 similarly to the other chablon rollers 27a to 27e, whereas the inking devices 28f and 28g are supported collectively by an inker frame 61 which can be drawn laterally (in the lateral direction), i.e., in the axial direction of the ink collecting cylinder 25.


It is needless to say that the present invention is not limited to the above-described examples, and various medications can be made without departing from the scope of the present invention. For example, the work space Sa may be formed between any other two adjacent chablon rollers. Also, the number of work spaces Sa is not limited to one. Moreover, each of the above-described examples has been described based on an intaglio printing press of five or more colors, i.e., an intaglio printing press including five or more chablon rollers 27a to 27g and five or more inking devices 28a to 28g. However, the present invention may be applied to an intaglio printing press of four colors, i.e., an intaglio printing press including four chablon rollers 27a to 27d and four inking devices 28a to 28d.


INDUSTRIAL APPLICABILITY

An intaglio printing press according to the present invention is suitable when used for a sheet-fed offset printing press for printing banknotes, securities, and the like.
