  The erection plate 17 is a horizontally long strip-shaped member, and a lower end thereof is in contact with an upper portion of the finisher roll 13 and sealed.

  By being partitioned by both side plates 18 and the erection plate 17, ink supplied from a coating liquid supply device (not shown) is stored in a gap above the portion where the finisher roll 13 and the plate cylinder 11 are in contact with each other. A liquid reservoir IR is formed.

  The doctor blade 14 is disposed on the side opposite to the finisher roll 13 with respect to the plate cylinder 11 and on the downstream side with respect to the rotation direction of the plate cylinder 11. The tip of the doctor blade 14 is in contact with the plate cylinder 11 in order to scrape off excess ink adhering to the plate cylinder 11 in the liquid reservoir IR.

  The plate cylinder 11 is detachably supported through a pair of support shafts 19 disposed on both side frames 15 and 15 in a state of facing each other. By retreating the support shafts 19, the plate cylinder 11 is detached from the side frames 15 and can be exchanged.

(Cart)
As shown in FIG. 4, in order to facilitate replacement of the plate cylinder 11, the printing apparatus 1 is provided with a dedicated carriage 30. The carriage 30 enters and exits the lower side of the coating apparatus 10 through an opening formed on the side surface of the one side frame 15 with the plate cylinder 11 placed thereon. The carriage 30 after delivering the plate cylinder 11 to the side frame 15 is disposed below the coating apparatus 10.

  The cart 30 includes a horizontally long rectangular frame body frame 31. A caster 32 is provided below the main body frame 31. A pair of guide members 33, 33 projecting opposite to each other are provided at the front of the main body frame 31.

  By sliding the slide frame 37, the plate cylinder 11 is positioned in a state where it can be attached to the coating apparatus 10.

  As shown in FIGS. 2, 3, and 4, a pair of guide plates 40, 40 are inclined below the plate cylinder 11 and the finisher roll 13 in order to catch ink that scatters or leaks during coating. It is assembled with. The ink received by these guide plates 40 flows into the ink receiver 38.

  A plurality of ink recovery boxes 41 are placed on the table 35. The ink that has flowed into the ink receiver 38 is collected in one of the ink collection boxes 41 via the swingable ink guide 34.

(Lifter)
The lifter 50 moves up and down the plate cylinder 11 and transfers the plate cylinder 11 between the carriage 30 and the side frame 15.

  The lifter 50 includes a horizontally long base frame 51. When the carriage 30 is carried in / out, the base frame 51 is fitted between the guide members 33 and 33, and the carriage 30 is slid straight. A pair of gear cases 52 are provided on the upper side of the base frame 51. These gear cases 52 are connected to a first motor 53 provided on the side frame 15.

  On the upper side of these gear cases 52, a support plate 54 that moves up and down by driving the first motor 53 is provided. Four lifting rollers 54 a are provided on the upper surface of the support plate 54.

(Replace plate cylinder)
First, prior to replacement of the plate cylinder 11, the pair of guide plates 40, 40 are removed.

  The carriage 30 on which the plate cylinder 11 is not mounted is fixed at a predetermined position below the printing apparatus 13, and as shown in FIG. 5A, the support plate 54 is raised to move the plate cylinder 11 up and down. Take it with. Then, the plate cylinder 11 is transferred from the side frame 15 to the lifter 50 by retreating both the support shafts 19.

  As shown in FIG. 5B, the support plate 54 is lowered and the plate cylinder 11 is received by the carriage roller 37a. After sliding the slide frame 37 and positioning the slide frame 37 with respect to the main body frame 31, the carriage 30 on which the plate cylinder 11 is placed is pulled out from below the coating apparatus 10 to replace the plate cylinder 11.

  After the plate cylinder 11 to be exchanged is placed on the carriage roller 37a in a state of being set in a predetermined direction, the carriage 30 is again placed under the coating apparatus 10 and shown in FIG. 5 (b). Thus, it is fixed at a predetermined position.

  After sliding the slide frame 37 and positioning the slide frame 37 with respect to the main body frame 31, as shown in FIG. 5A, the support plate 54 is raised, and the plate cylinder 11 is moved by the lifting roller 54a. Receive it and raise it to the mounting position. Then, both support shafts 19 and 19 are advanced to attach the plate cylinder 11 to the side frame 15.

  Finally, the pair of guide plates 40, 40 are attached at predetermined positions.

  In relation to the present invention, Patent Document 3 discloses a gravure printing machine provided with a chamber-shaped ink pan that substantially seals the periphery of a plate cylinder and an inking roll (corresponding to a finisher roll).

  The gravure printing machine is also provided with a solvent frequency device for sucking air in the ink pan and collecting the volatilized solvent.

JP 2013-144384 A JP 2013-86270 A JP 2004-174732 A

  In the case of the printing apparatus disclosed in Patent Documents 1 and 2, since the plate cylinder is detached from below by the lifter, when the chamber-shaped ink pan as in Patent Document 3 is assembled, when replacing the plate cylinder, The ink pan also needs to be detached from the printing apparatus, and lacks workability.

  For this reason, the printing apparatus 1 of Patent Documents 1 and 2 uses a pair of guide plates so that it can be attached and detached in a short time.

  However, the plate cylinder replacement work is often performed at once by a plurality of printing apparatuses, so that the work load is large only by attaching and detaching the guide plate, and there is room for improvement. Further, in the case of a pair of guide plates, there are many open portions, which is disadvantageous in terms of preventing diffusion of the volatile solvent.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a printing apparatus in which a plate cylinder can be replaced with a simpler operation and diffusion of volatilized solvent can be suppressed.

  The disclosed printing apparatus continuously prints on the web being conveyed. The printing apparatus is detachably pivotally supported between a pair of side frames arranged opposite to each other, and a plate cylinder for transferring ink in contact with the web in a rotated state, an ink pan surrounding the plate cylinder, And a lifter that raises and lowers the plate cylinder between an attachment position attached to the pair of side frames and a standby position below the attachment position.

  The ink pan is formed in a container shape that covers at least the lower side and the side of the plate cylinder, and is configured to be movable in a substantially horizontal direction.

  Since the ink pan is formed in a container shape that covers at least the lower side and the side of the plate cylinder, the leaked ink can be efficiently recovered and the diffusion of the volatile solvent can be suppressed. Since the ink pan is configured to be movable in a substantially horizontal direction, the plate cylinder can be moved up and down by the lifter without any trouble by moving the ink pan when replacing the plate cylinder. Therefore, the plate cylinder can be easily replaced in a short time.

  The ink pan is preferably configured to be slidable in the radial direction of the plate cylinder.

  Then, by sliding the ink pan in the radial direction, the ink pan can be separated from the plate cylinder at a shorter distance than in the axial direction of the plate cylinder. Therefore, the entire apparatus can be configured compactly.

  In particular, in the case of further comprising a doctor blade that is in contact with the side of the plate cylinder, and a finisher roll that is in contact with the side of the plate cylinder from the opposite side of the doctor blade, the ink pan is provided on the finisher roll. It may be configured to be slidable to the side.

  If it does so, it will become possible to fully cover the side of the finisher roll which ink tends to scatter with an ink pan. Therefore, the leakage of ink and the diffusion of the volatile solvent can be effectively prevented.

  Further, a flexible sheet wound in a roll shape is attached to the ink pan, and the sheet is intermittently unwound and placed inside the ink pan.

  By doing so, the ink hardly adheres to the inner surface of the ink pan, so that it is possible to omit the ink pan cleaning operation that had to be performed every replacement, and the ink can be recovered appropriately. Therefore, the work load is reduced and the workability is excellent.

  In this case, it is preferable that a winding mechanism for winding the unwound sheet is attached to the ink pan.

  This makes it possible to wind up the dirty sheet intermittently and dispose it in a lump, further improving workability.

  In addition, a solvent recovery device that recovers the volatilized solvent may be further provided, and the solvent recovery device may suck the solvent that has already occurred around the plate cylinder through an air inlet that faces the inside of the ink pan.

  Then, the diffusion of the volatile solvent can be effectively suppressed, and the volatile solvent can be efficiently recovered and reused.

  In this case, it is preferable that the air inlet is disposed on the top of the ink pan.

  Since the solvent that volatilizes around the plate cylinder tends to accumulate inside the ink pan, the solvent can be efficiently recovered and a good working environment can be maintained.

  The apparatus further comprises a solvent recovery device and a bowl-shaped ink receiver that receives the ink flowing out of the ink pan, and the solvent recovery device has an intake port disposed in the vicinity of the ink receiver. The solvent may be sucked through.

  Then, when the ink flowing out from the ink pan flows through the ink receiver, the solvent is volatilized from the ink receiver. However, the solvent recovery device can recover the solvent through the air inlet arranged in the vicinity of the ink receiver. As a result, the work environment can be maintained even better.

  According to the printing apparatus of the present invention, the plate cylinder can be replaced with a simpler operation, and the diffusion of the volatilized solvent can be suppressed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the following description is merely illustrative in nature and does not limit the present invention, its application, or its use.

  FIG. 6 shows the printing apparatus 2 of the present embodiment. Since the basic configuration of the printing apparatus 2 is the same as that of the printing apparatus 1 described above, the same members and configurations will be omitted using the same reference numerals, and different members and configurations will be described in detail.

(Ink pan)
The printing apparatus 2 is provided with a devised container-shaped ink pan 60. That is, at the time of printing, a specific portion around the plate cylinder 11 is surrounded by the ink pan 60 to collect the leaked ink and the volatilizing solvent. The lower part can be opened.

  As shown in FIGS. 6 and 7, the ink pan 60 is formed in a horizontally long container shape having an open upper surface, and includes a first bottom wall portion 61, a second bottom wall portion 62, a first side wall portion 63, 2 side wall part 64 and a pair of end wall part 65,65.

  The first bottom wall portion 61 is a horizontally long rectangular plate-like portion, and extends below a portion from the plate cylinder 11 to the finisher roll 13. The second bottom wall portion 62 is a horizontally long rectangular plate-like portion, and extends from the lower side of the finisher roll 13 in a direction away from the plate cylinder 11.

  The first bottom wall portion 61 and the second bottom wall portion 62 are inclined in a V shape so as to approach each other downward. The lower end of the first bottom wall portion 61 and the lower end of the second bottom wall portion 62 are separated from each other, and a horizontally long outlet 66 is formed therebetween.

  The first side wall portion 63 extends upward from the upper edge of the first bottom wall portion 61, and the second side wall portion 64 faces the first bottom wall portion 61 and faces the upper edge of the second bottom wall portion 62. It spreads upward from the top. Each of the first side wall 63 and the second side wall 64 is a horizontally long rectangular portion, and the second side wall 64 is formed higher than the first side wall 63.

  Specifically, the upper edge of the first side wall 63 is located below the lower end of the support shaft 19 that supports the plate cylinder 11, whereas the upper edge of the second side wall 64 is the plate cylinder. 11 is located at the upper end or above it.

  The pair of end wall portions 65, 65 are portions that are connected to the respective end edges of the second side wall portion 64, the first side wall portion 63, and the second side wall portion 64, and block both end portions of the ink pan 60. Each end wall portion 65 extends substantially horizontally at a low edge 65a having a low height extending substantially horizontally from the first side wall portion 63 side, and at a higher position than the low edge portion 65a from the second side wall portion 64 side. It has a high edge portion 65b, and a step edge portion 65c extending substantially perpendicularly to the low edge portion 65a and the high edge portion 65b.

  By arranging the ink pan 60 in such a container shape so that the support shaft 19 is positioned at the corner of the step edge portion 65c, the plate cylinder 11 and the finisher roll 13 extend from the bottom to the side. Can be efficiently covered with the ink pan 60.

  Since the liquid reservoir IR for storing ink is positioned at the approximate center in the width direction of the ink pan 60, it is possible to effectively suppress the ink from coming out of the ink pan 60.

  Although the plate cylinder 11 side of the ink pan 60 is relatively low, the plate cylinder 11 has a diameter larger than that of the finisher roll 13 and the plate cylinder 11 blocking the ink is the liquid in the liquid reservoir IR. Since it is sufficiently higher than the surface, the ink is structurally difficult to leak to the plate cylinder 11 side.

  On the other hand, the finisher roll 13 side of the liquid reservoir IR is only dammed up by the low erection plate 17, so that ink easily leaks out. Therefore, by making the finisher roll 13 side of the ink pan 60 relatively high, it is difficult for the ink to leak from both sides of the ink pan 60.

  The ink pan 60 is movable in a substantially horizontal direction so that the plate cylinder 11 can be easily replaced.

  Specifically, a pair of guide rails 67, 67 extending in parallel in the substantially horizontal direction is attached to each side frame 15. A guide roller 68 that rolls along these guide rails 67 is attached to the outer surface of each end wall portion 65. The ink pan 60 is slidably supported on the side frame 15 via the guide rail 67 and the guide roller 68.

  The ink pan 60 is shown in FIG. 6 in which the support shaft 19 is located at the corner between the low edge portion 65a and the step edge portion 65c and the entire plate cylinder 11 is surrounded by the ink pan 60 (use position). The entire plate cylinder 11 moves away from the first side wall portion 63 and moves between the ink pan 60 and a position located side by side (non-use position). Usually, the ink pan 60 is in the use position, and the ink pan 60 is moved to the non-use position only when the plate cylinder 11 is replaced.

  That is, the ink pan 60 is separated from the plate cylinder 11 by sliding to the finisher roll 13 side in the radial direction of the plate cylinder 11. The movement of the ink pan 60 may be performed manually or mechanically by control using an actuator or the like.

  By sliding the ink pan 60 not in the axial direction but in the radial direction of the plate cylinder 11, the ink pan 60 can be separated from the plate cylinder 11 at a short distance, and the entire apparatus can be configured compactly. Moreover, even if the ink pan 60 is in the non-use position, the replacement operation of the plate cylinder 11 is mainly performed on the axial direction side of the plate cylinder 11, so that the operation is not disturbed.

  By sliding the ink pan 60 to the side of the finisher roll 13, the second side wall portion 64 and the high edge portion 65 b of the end wall portion 65 are raised, and the side of the finisher roll 13 where ink is easily scattered is placed on the ink pan 60. With this, it is possible to sufficiently cover the ink, and the leakage of ink can be effectively prevented.

  In the use position, the outlet 66 that opens to the lower end of the ink pan 60 is positioned so as to overlap the ink receiver 38. Accordingly, the ink dropped into the ink pan 60 flows out through the outlet 66 and is received by the ink receiver 38.

  As shown in FIG. 6, ink collection boxes 41 (two in this case) are placed on the cradle 35. The ink receiver 38 is inclined so that the end portion on the ink guide portion 34 side is lowered, and the ink that has flowed into the ink receiver 38 is guided to the ink guide portion 34 side, and passes through the ink guide portion 34. The ink is collected in the ink collection box 41 for the ink.

(Solvent recovery device)
A solvent recovery device 70 is attached to the printing apparatus 2. The solvent recovery device 70 has a function of sucking air containing a solvent through the intake pipe 71 and recovering the solvent. A known device can be used as the solvent recovery device 70.

  The intake pipe 71 communicates with each of the first intake port 72 and the second intake port 73. As shown in FIG. 7, the first air inlet 72 is disposed at the top of the ink pan 60 and is formed so as to face the inside thereof. The solvent that volatilizes from the ink generally has a higher specific gravity than air, and therefore the solvent that volatilizes around the plate cylinder 11 tends to accumulate inside the ink pan 60.

  Therefore, by disposing the first air inlet 72 at the upper part of the ink pan 60 and sucking the air inside the ink pan 60, the solvent can be effectively recovered and a good working environment can be maintained.

  As shown in FIG. 6, the second air inlet 73 is disposed in the vicinity of the lower end portion of the bowl-shaped ink receiver 38 whose upper portion is open.

  Specifically, the intake pipe 71 branches in the middle, and one of the branched pipes is connected to a flexible and large-diameter intake hose 71a. The end of the intake hose 71 a serves as a second intake port 73 and is disposed in the vicinity of the lower end portion of the ink receiver 38.

  When the ink flows into the ink recovery box 41, the ink flow tends to be disturbed and thus tends to volatilize. Therefore, by disposing the second air inlet 73 in the vicinity of the lower end portion of the ink receiver 38, the solvent flowing out from the ink pan 60 can be effectively recovered, and a good working environment can be maintained.

(Stain for preventing dirt)
Ink adheres to the inside of the ink pan 60. When the color or type of the ink is changed, it is necessary to clean the inside of the ink pan 60 and remove the adhered ink when replacing the plate cylinder 11 so as not to be mixed into the recovered ink. Since the adhered ink cannot be easily removed, cleaning the ink pan 60 is a time-consuming operation.

  Therefore, it is preferable to attach a replaceable anti-stain sheet 80 as shown in FIG.

  The sheet 80 is made of a flexible long sheet 80 such as polyethylene or paper, and is wound around a long cylindrical core member 80c in a roll shape in a state where both end portions are bent oppositely on the same surface side. It has been.

  Specifically, the sheet 80 has a band shape, and includes a main portion 80a and a pair of bent edge portions 80b and 80b connected to both side portions thereof. The width of the main portion 80 a is set to be approximately the same as the inner dimension in the longitudinal direction of the ink pan 60, and the width of the bent edge portion 80 b is about half the inner dimension in the height direction of the ink pan 60. Is set to

  In this case, as shown in FIG. 10, an unwinding mechanism 81 and a winding mechanism 82 are installed below the ink pan 60.

  The unwinding mechanism 81 and the winding mechanism 82 support the core member 80c around which the sheet 80 is wound in a state where it can be detached and rotated. A handle 82a is installed in the winding mechanism 82 so that it can be easily operated.

  The core member 80c around which the sheet 80 is wound is mounted on the unwinding mechanism 81, unwinds the unwinding end of the sheet 80, pulls out the sheet 80 along the outer surface and the inner surface of the ink pan 60, and then is wound on the winding device. The unwinding end is wound around the attached core member 80c.

  The sheet 80 pulled out in this way is laid inside the ink pan 60. At that time, both bent edge portions 80 b and 80 b are opened upward and are along the inner surface of the end wall portion 65, so that the entire area inside the ink pan 60 is covered with the sheet 80. The portion of the sheet 80 that covers the outlet 66 may allow ink to flow out.

  When printing is performed, most of the ink falling into the ink pan 60 does not adhere to the ink pan 60 but adheres to the sheet 80.

  When the ink is exchanged or the like, the handle 82a is operated to take up the dirty sheet 80 by the take-up mechanism 82, unwind the sheet 80, and turn the dirty sheet 80 into an unused sheet 80. It only has to be replaced.

  Accordingly, in this case, since ink hardly adheres to the inner surface of the ink pan 60, the cleaning operation of the ink pan 60 that has to be performed every replacement can be omitted, and the ink can be collected appropriately, so the work load is reduced. Excellent workability.

  The printing apparatus according to the present invention is not limited to the above-described embodiment, and includes various other configurations.

  Although the printing apparatus 2 of the embodiment has been described by taking the top feed type coating apparatus 10 as an example, the so-called dove dipping type coating apparatus 10 that stores ink in an ink pan and supplies the ink to a plate cylinder is also used. Applicable.

  As shown in FIG. 11, the unwinding mechanism 81 and the winding mechanism 82 may be arranged together on the side where the work of the ink pan 60 is performed.

  Specifically, the unwinding mechanism 81 and the winding mechanism 82 are installed on the second side wall portion 64 side so as to line up and down. Guide bars 83 for supporting and guiding the sheet 80 are preferably installed at a plurality of locations on the outer surface of the ink pan 60 so that the sheet 80 does not loosen greatly.

  In this case, since the sheets 80 of both the unwinding mechanism 81 and the winding mechanism 82 can be easily exchanged, work efficiency can be improved.
