Description

  The present invention relates to a vise device for attaching a plate to a plate cylinder.

  There are various types of rotary printing presses such as a web-type rotary printing press that continuously supplies a web (printing paper) and a sheet-fed printing press that intermittently supplies a sheet as printing paper. As shown in FIG. 7, a general sheet-fed printing machine includes a sheet feeding device 56, a plurality of sets of printing devices 55 a to 55 d, a sheet discharge device 57, and a sheet stacking device provided on the lower side of the downstream end of the sheet discharge device 57. 58 and so on. The sheets 61 fed one by one from the sheet feeding device 56 are subjected to predetermined printing in the middle of passing through the next process printing device 55, and then discharged from the sheet stacking device 58 located below the sheet discharging device 57. After being stacked on the table, it is unloaded as a predetermined number of bundles. In FIG. 7, FL indicates a floor, and T indicates an intermediate cylinder. In such a sheet-fed printing machine, a plurality of sets of printing devices 55a to 55d having different ink colors are arranged side by side in the traveling direction of the sheet 61. By superimposing the two, multi-color printing can be performed.

  For example, as shown in Patent Document 1, the plate cylinder 62 is provided with a plate vise for attaching the plate 11. This plate vise is composed of a tail side vise R shown in FIG. 8 and a tail edge side vise S shown in FIG. The plate 11 is mounted by first inserting and gripping the front end of the plate 11 between the upper teeth 52 and the lower teeth 53 opened in the gripping side vise R, and then pressing the surface of the plate 63 with the pressing roller 54. The plate cylinder 62 is rotated in the direction of the arrow X in FIG. 8, and finally the rear end bent portion of the plate 11 is intermediate between the upper teeth 64 and the lower teeth 65 opened by the tail edge side vise S. Is carried out by inserting and gripping.

  Next, the ink sequentially transferred from the ink supply unit of the printing apparatus 55 is transferred from the plate 11 mounted on the plate cylinder 62 to the blanket cylinder (rubber cylinder) 59 shown in FIG. The image is transferred to the sheet 61 traveling in the middle, and printing is thereby performed.

The tail edge side vise S described above includes a rail 66 fixed in the axial direction in the groove portion of the plate cylinder 62, and a sliding plate 67 that can move along the rail 66, as shown in FIG. A pedestal 68 provided so as to be movable with respect to the sliding plate 67, a lower tooth 65 that is movable in the left-right direction in the figure with respect to the pedestal 68, and a bolt 69 and a spherical washer 70 to the lower tooth 65 The upper teeth 64 attached thereto, the compression spring 71 acting to close the upper teeth 64, the opening / closing cam 72 of the upper teeth 64, the upper teeth 64 and the lower teeth 65, and the rail 66. It is composed of a cam 73 or the like that moves in a right angle direction.

  In a printing machine that performs such multicolor printing, the pattern printed on the sheet 61 by each of the printing devices 55a to 55d is added with dampening water or blanket from the tail side to the tail edge side. The sheet 61 may gradually extend in the vertical direction (the front-rear direction of the plate 11) due to the printing pressure from the cylinder 59 or the like. Due to this elongation, parallelism and right angle are distorted, and misregistration (fan-out) occurs such that the pattern (ink) transferred on the same sheet 61 is displaced. Therefore, there arises a problem that the printing surface becomes unclear due to the misregistration and the quality is remarkably deteriorated. Therefore, the sheet-fed printing press employs a method of correcting the above-described misregistration by moving the tail edge side vise S toward the top and bottom of the plate 11 and stretching the plate 11 with the plate 11 attached. ing.

  However, in order to stretch the plate 11 in the vertical direction, the holding force of the plate 11 of the plate vise must be increased. In the conventional structure, in order to mesh the plate 11 with the upper teeth 64 (52) and the lower teeth 65 (53), the opening / closing cam 72 is brought into contact with the upper teeth 64, and the cam surface and the upper teeth are slid. The upper teeth 64 are moved by moving them. In this sliding structure, there is a limit in increasing the meshing force between the upper teeth 64 and the lower teeth 65 because the frictional force of the contact surface becomes a barrier. Also, a large driving force for rotating the opening / closing cam 72 is required.

  FIG. 3 is a cross-sectional view taken along the line BB in FIG. 1 and shows a state where the plate 11 is wound around and attached to the plate cylinder 1. First, the configuration of the tail edge side vise 5 will be described. The tail edge side vise 5 is provided with upper teeth 7 and lower teeth 8 extending in the longitudinal direction of the plate cylinder 1. The upper teeth 7 are provided with a rotation shaft 9 extending along the longitudinal direction of the plate cylinder 1. The upper teeth 7 rotate around the rotation shaft 9 and mesh with the lower teeth 8. In the portion 10, the plate bottom 11b (the rear end portion of the plate) of the plate 11 is held. In addition, a tapered surface (contact surface) 7 a that is in contact with a rolling surface of a cam follower 14 described later is formed at the lower portion of the upper teeth 7. The taper surface 7a is provided on the tail side vise 6 side with respect to the rotation shaft 9, and has a gentle downward slope having a predetermined angle along the clockwise rotation direction of the turning shaft described later. It is formed on an inclined surface. For this reason, the lower end part of the upper teeth 7 on the tail side vise 6 side is located at the lowest position.

  As shown in FIG. 1, the tail edge side vise 5 is configured by four divisions in the longitudinal direction of the plate cylinder 1, and one of the four divisions is enlarged and shown in FIG. 4. As shown in FIGS. 3 and 4, the lower teeth 8 are provided with a turning shaft 12 extending along the axial direction of the plate cylinder 1, and the upper teeth are rotated on the outer peripheral surface of the turning shaft 12. Rotating means 13 for moving is attached. The turning shaft 12 can be assembled as a single shaft by connecting the end portions 12a of the four divided shafts, and both ends of the assembled turning shaft 12 are connected to the plate cylinder 1. It extends to the end, and is configured to turn the end of the turning shaft 12 manually or with an actuator.

  FIG. 5 is a perspective view showing a state in which the turning shaft 12 and the rotating means 13 are disassembled. The rotating means 13 includes a cam follower 14 that can rotate around an axis substantially parallel to the rotation axis 2 of the plate cylinder, a shaft 18 to which the cam follower 14 is attached, a bearing 15 and a block 16 for attaching the shaft 18.

A bearing 15 and a block 16 are attached to the shaft 18, and the block 16 is attached to the outer peripheral surface portion of the turning shaft 12 via a spring spring 17. The mounting hole of the bearing 15 to which the shaft 18 is attached is formed such that the diameter of the mounting hole is larger than the outer diameter of the shaft 18, and the shaft 18 biased by the spring 17 is in the mounting hole. It can move.

  Next, the configuration of the tail side vise 6 will be described. As shown in FIGS. 2 and 3, the preparation side vise 6 is divided into three parts in the axial direction of the plate cylinder 1, and includes upper teeth 19 and lower teeth 20. The plate cylinder 1 is provided with a cam shaft 21 extending in the axial direction thereof, and the upper teeth 19 are provided with a cam follower (second rotating body) 22 that contacts the cam surface of the cam shaft 21. The cam follower 22 is disposed below the cam shaft 21 and can rotate on an axis substantially parallel to the cam shaft 21. The rotating shaft of the cam follower 22 is attached to the upper teeth 19 via a biasing spring 23 of a biasing means, and the biasing spring 23 biases the cam follower 22 upward.

  The cam shaft 21 has a substantially cylindrical shape, and in the cross-sectional shapes shown in FIGS. 3 and 6A to 6C, a part of the outer peripheral surface is cut away to form the first flat portion 21a. Has been. A pin 24 fixed to the upper tooth 7 comes into contact with the flat surface portion 21a. Further, on the outer peripheral surface of the cam shaft 21, a second flat surface portion 21 b (a dotted line in FIGS. 6A to 6C) formed at a position shifted from the first flat surface portion 21 a in the longitudinal direction of the cam shaft 21. Is formed). The rolling surface of the cam follower 22 is in contact with the second flat surface portion 21b.

  Next, the operation of the tailoring vise according to the embodiment of the present invention will be described using FIG. 3 and FIG.

First, I will explain the vise vise. When the camshaft 21 protruding from the end of the plate cylinder 1 is rotated clockwise as shown in FIG. 6A, the first flat surface portion 21a does not face the pin 24, and the first The two flat portions 21 b are in contact with the cam follower 22. In this state, the cam surface pushes the pin 24 upward, and the engagement between the upper teeth 19 and the lower teeth 20 is open, and the front end portion 11a (see FIG. 3) of the plate 11 is connected to the upper teeth 19. It can be set between the lower teeth 20.
In the state where the camshaft 21 is rotated counterclockwise as shown in FIGS. 6B and 6C from the state of FIG. 6A, the first flat portion 21a faces the pin 24. The second flat surface portion 21b is released from contact with the cam follower 22. In this state, since the cam surface of the cam shaft 21 does not push up the pin 24, the meshing between the upper teeth 19 and the lower teeth 20 closes, and the cam follower 22 pushed down by the cam shaft 21 pushes down the cam follower shaft. Since the upper teeth 19 are pushed down with a predetermined force through the spring 23 that biases the cam follower shaft, the plate 11 can be gripped by the engagement of the upper teeth 19 and the lower teeth 20.

  Next, the tail bottom side vise will be described. In a state where the pivot shaft 12 protruding from the end of the plate cylinder 1 is rotated counterclockwise in FIG. 3, the cam follower 14 is not in contact with the tapered surface 7 a of the upper tooth 7, and the upper tooth 7 is It can be freely rotated clockwise about the rotation axis 9. The upper teeth and cam followers in this state are indicated by a two-dot chain line in FIG.

  When the plate 11 is wound around the plate cylinder 1, the rear end portion 11 b (plate end) of the plate 11 is set in the meshing portion 10, and the turning shaft 12 is rotated clockwise, the cam follower 14 rotates the turning shaft 12. It moves in the direction and comes into contact with the tapered surface 7 a of the upper tooth 17. Then, the cam follower 14 gradually pushes up the upper teeth 7 through the tapered surface 7a having the downward inclined surface while rotating. In this state, the block 16 and the bearing 15 attached to the turning shaft 12 are pushed upward by the urging force of the spring spring 17, and accompanying this, the cam follower 14 is connected via the shaft 18 supported in the attachment hole of the bearing 15. Is pushed up with a predetermined force, the upper teeth 7 rotate counterclockwise about the rotation shaft 9, and the engagement between the upper teeth 7 and the lower teeth 8 causes the rear end portion 11 b of the plate 11 at the engagement portion 10. Can be praised. The shape of the tapered surface 7a is formed at a predetermined inclination angle so that the meshing force of the upper teeth 7 and the lower teeth 8 can be adjusted by the rotation angle of the turning shaft 12, so that the meshing is performed by managing this rotation angle. The force can be adjusted.

  In the tailored vise apparatus of the sheet-fed printing press according to the embodiment of the present invention, the upper teeth 7 can be rotated without sliding the taper surface 7a and the rotating body 14, so A large force can be obtained without requiring an excessive torque for rotation. In addition, since no excessive torque is required, the turning shaft 12 is not twisted, and a uniform holding force can be obtained in the longitudinal direction of the plate cylinder 1. Further, the cam follower 14 and the tapered surface 7a are not worn.

  Further, the tailing force can be adjusted and managed by the turning angle of the turning shaft 12. Further, since the shaft end portion of the turning shaft 12 is configured to be turned manually or by an actuator, the work of holding the plate 11 can be easily performed. On the other hand, by eliminating the sliding movement of the tail side vise 6, it is possible to increase both the tailing force of the tail side vise and the tail side vise.

The best mode for carrying out the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. .
For example, in the tail edge side vise 5, the cam follower 14 is provided on the upper tooth 7 side and the tapered surface 7 a is provided on the revolving shaft 12 side, whereby the same effect as in the above-described embodiment can be obtained.
