Definitions
- the present invention relates to a slip sheet take-out device that takes out a slip sheet from a storage section in which printing plates and slip sheets are alternately stacked.
- An interleaf take-out device is used in a plate supply device that automatically supplies a plate to an image recording device.
- FIG. 6 is a drawing showing the internal structure of a plate supply device 2 for supplying a plate to an image recording device (not shown).
- a plurality of printing plates 4 and interleaf sheets 5 for preventing the printing plates 4 from rubbing each other are alternately stacked.
- the leading end of the printing plate 4 is gripped by the printing plate suction pad 82 of the printing plate pad unit 81, is taken out of the cassette 30, and is carried to the pair of discharge rollers 15 3, 15 4.
- the pair of discharge rollers 15 3 and 15 4 send out the printing plate 4 to an image recording device (not shown).
- the leading edge of the slip sheet 5 is gripped by the slip sheet suction pad 2 31 of the slip sheet pad unit 19 1.
- the slip sheet 5 is lifted until it is sandwiched between the nip roller 199 and the slip sheet discharge roller 206.
- the slip sheet 5 is discharged from the slip sheet discharge hole 53 to the outside of the plate supplying device 2 by rotation of the nip roller 199 and the slip sheet discharge roller 206.
- the detailed configuration of the plate supply device 2 is described in a patent application filed by the present applicant (Patent Application No. 501/280, 2001), and will not be described in detail here.
- the slip sheet 5 is sucked and fixed by the slip pad 2 3 1, but if the slip sheet 5 is air permeable, the slip pad 2 3 1 passes through the slip sheet 5 and the printing plate 4 below it. Suck May be fixed. Also, even when the backing sheet 5 has no air permeability, the printing plate 4 may adhere to the back surface of the interleaving sheet 5 due to static electricity.
- this problem is referred to as a two-sheet problem.
- the bracket 2 12 of the slip-sheet pad unit 19 1 is attached to the first vertical belt 2 25 and the first guide shaft 2 10 which are rotated by a driving device (not shown). These make it possible to move up and down.
- two vertical shafts 236 are attached to both ends of the lower surface of the bracket 211 in the Y direction (a direction perpendicular to the paper surface of FIG. 7).
- pad holding plates 237 which are long in the Y direction are provided so as to be vertically movable with respect to the brackets 212.
- the pad holding plate 237 is urged downward (in the _Z direction) by a spring 241 around a vertical shaft 236.
- FIG. 7 is an enlarged view of the vicinity of the interleaving paper suction pad 231 of the interleaving paper pad unit 191.
- a rod 238 and an interleaf paper suction pad 231 are attached, and on its side surface, a connecting plate 239 and a pressing rod 2400 are attached.
- the suction tube communicating with the slip-sheet suction pad 2 3 1 is not shown.
- the length of each of the pressing rod 2 40, the rod 2 3 8 and the slip-sheet suction pad 2 3 1 is as follows.
- the tip of 40 is set so that it is almost the same height as the suction surface of the slip sheet suction pad 2 31 when the tip is not operated (when suction is not performed).
- the slip sheet 5 Since the slip sheet 5 has low elasticity, it can be bent in this way, but since the printing plate 4 has higher elasticity, the printing plate 4 does not follow the bending of the mount 5. Therefore, a gap is generated between the back surface of the slip sheet 5 and the printing plate 4.
- the present invention has been made in view of the above problems, and it is possible to take out the slip sheets one by one without damaging the printing plates from a storage portion in which the printing plates and the slip sheets are stacked.
- the purpose is to provide a slip sheet removal device.
- the present invention relates to an interleaf take-out device, comprising: a storage portion for storing alternately stacked printing plates and interleaving paper; and interleaf holding means for gripping an uppermost interleaving paper in the storage portion. And an interleaf holding means moving means for bringing the interleaf holding means close to the interleaf and separating from the interleaf, and a contact portion for abutting on the uppermost interleaf.
- a force is applied to the slip sheet in a direction substantially parallel to the surface of the slip sheet, whereby the slip sheet is gripped by the slip sheet gripping means.
- Interleaving sheet separating means for separating a part of the interleaving paper from the printing plate thereunder; and said interleaving paper gripping means is moved to a desired position by the interleaving paper gripping means moving means.
- Control means for releasing the slip sheet from the slip sheet holding means.
- the abutment applies a force in a direction substantially parallel to the surface of the slip sheet to separate the slip sheet from the plate below.
- the slip sheet gripping means grips the separated portion and takes out the entire slip sheet from the storage portion.
- the contact portion applies a force in a direction substantially parallel to the surface of the slip sheet to separate a part of the slip sheet, so that the plate below it is not damaged. Moreover, it is possible to reliably prevent the slip sheet from being taken out with the printing plate adhered.
- the pedestal holding means is provided with a pedestal for holding the interleaf holding means, and a contact portion of the interleaf separating means is connected to the pedestal.
- the contact portion is rotatably connected to the base, and the rotation applies a force to the mount in a direction substantially parallel to the surface of the slip sheet. Since the substantially horizontal force is applied by the rotation of the contact portion, it is possible to configure the slip sheet removing device with a simple configuration.
- the present invention provides a slip sheet holding means for sucking and fixing the slip sheet in the slip sheet holding means, and before contacting the slip sheet with the contact portion, at a position closer to the slip sheet than a suction surface of the sucker. It's a storm.
- the suction cup Before the suction cup contacts the uppermost slip sheet, the uppermost slip sheet is partially separated from the printing plate by the abutment. Therefore, since the suction cup can suction-fix the separation portion formed in this way, the suction cup can surely suction-fix only the uppermost slip sheet.
- the storage portion is provided with a guide portion for restricting movement of the entire slip sheet in a direction substantially parallel to the slip sheet surface.
- Separation of the slip sheet by the contact portion can be performed more reliably.

- the pad holding plate 237 is penetrated by the vertical shafts 236 and 236 just below the bracket 212 so as to be vertically movable with respect to the bracket 211.
- the pad holding plate 237 is a member elongated in the Y direction, having a U-shaped cross section cut in the XZ plane.
- nine interleaf paper suction pads 2 3 1 are attached by mounting screws 2 5 3, respectively.
- FIG. 3 is a side view showing a configuration near the two-sheet take-off prevention mechanism 246. A part of the cassette 30 is also shown. In this figure, the stage at which the bracket 2 12 has been lowered until a part of the two-sheet take-off prevention mechanism 2 46 (the tip of the abutment plate 2 64 described later) contacts the surface of the slip sheet 5 is shown. I have.
- the two-sheet take-off prevention member 2464 mainly includes a frame 251, a plate 260, and a contact plate 264.
- the frame 2 51 is made by bending the sheet metal with the required cuts at three points, and the right side 2 4 7, the left side 2 4 8 parallel to this, and the fixing 2 4 9 , With a base 250.
- the left piece 248 is not shown in FIG.
- the two-sheet take-off preventing member 2 46 is fixed to the pad holding plate 2 37 by connecting the fixing piece 2 49 and the pad holding plate 2 37 with a connecting bolt 25 2.
- the plate 260 has a right side mounting piece 256 and a left side mounting piece 256 (not shown in FIG. 3). These mounting pieces 25 6 and 25 58 are fixed to the right side piece 2 47 and the left side piece 2 48 of the frame 25 1 by mounting screws 25 4. Thus, the plate 260 is connected to the pad holding plate 237 through the frame 247.
- the plate 260 is a panel panel bent at the position of the fold 261, and its tip has a rotational moment in the direction of the arrow f around the fold 261.
- a regulating shaft 266 is provided between the left and right side pieces 247 and 248 of the frame body 251. This member is a member for limiting the rotation of the plate 260.
- the tip of the plate 260 is fixed by a contact plate 264 force bolt 262.
- the contact plate 26 4 is a member that comes into contact with the slip sheet 5 in the cassette 30 as described later, and is made of rubber.
- the tip of the contact plate 264 becomes the suction surface 224 of the slip sheet suction pad 231 in the non-suction stage.
- the dimensions and the like of each member are set so as to be below.
- the X coordinate of the position where the tip of the contact plate 2 64 contacts the mount 5 is defined as X 1.
- the X-direction end faces of the printing plate 4 and the slip sheet 5 stored in the cassette 30 are regulated by a plate guide 52 mounted on a bottom plate of the cassette 30.
- the bracket 2 12 is further lowered to bring the suction surface 2 42 of the slip-sheet suction pad 2 3 1 into contact with the slip sheet 5.
- the leading end of the contact plate 26 comes in contact with the slip sheet 5 with the above-mentioned descent.
- the contact plate 2 64 rotates counterclockwise about the fold 2 61. By this rotation, the tip of the contact plate 264 applies a force to the slip sheet 5 in the X direction (horizontal direction; a direction substantially parallel to the surface of the slip sheet 5).
- the tip of the contact plate 264 does not slide on the surface of the slip sheet 5 during the rotation.
- FIG. 4 is a view showing a stage in which the suction surface 2422 of the slip sheet suction pad 231 is lowered until it comes into contact with the uppermost slip sheet 5.
- FIG. 4 As shown in this figure, the X coordinate of the tip position of the contact plate 264 has moved by a distance d x from X 1 to X 2. As described above, since the abutment plate 2 6 4 does not slide on the slip sheet 5, the slip sheet 5 also moves by the same distance.
- the expansion portion 268 is shown on the suction surface 242 of the slip-sheet suction pad 231, but in actuality, the slip-sheet suction pads 231 and 2
- the position of the sheet-prevention mechanism 246 in the Y direction has shifted (see Fig. 1).
- FIG. 5 shows a stage in which the slip pad for suction paper 23.1 starts suctioning by a suction pump (not shown).
- the suction pad 2 31 for the slip-sheet shrinks and its suction surface 2 42 rises. Even if the uppermost slip sheet 5 and the lower printing plate 4 were stuck together due to static electricity, they would still be inflated at the stage 2 6 8 formed at the stage shown in Fig. 4 (before starting suction). It has come out of close contact because of. Therefore, the slip sheet suction pad 2 31 does not suck and fix the printing plate 4 thereunder through the slip sheet 5.
- the suction surface 2 42 may be used.
- the space between the facing slip sheet 5 and the printing plate 4 therebelow is open to the expansion section 268 formed in the front and rear position in the Y direction, and from the expansion section 268 as suction starts. Since air flows into the space, the slip sheet suction pad 2 31 does not suck and fix the printing plate 4 thereunder through the slip sheet 5. Thereafter, the brackets 2 12 rise to a height where the end of the slip sheet 5 can be sandwiched between the slip sheet discharge roller 206 and the nip roller 199 (see FIG. 6).
- the rubber contact plate 264 applies a force to the slip sheet 5 in a direction substantially parallel to the surface of the slip sheet 5 through the suction process to form the expanded portion 2 68, and the slip sheet 5 Since the plate is separated from the plate 4, the two-sheet take-off prevention mechanism 2 46 does not damage the plate 4.
- the two-sheet pick-up preventing mechanism 2 46 is connected to the pad holding plate 2 37 together with the slip sheet suction pad 2 31, and moves up and down simultaneously with the slip sheet suction pad 2 31.
- the present invention is not limited to this, and the mechanism for preventing two sheets may be attached to another member, for example, the cassette 30.
