Description

[Detailed description of the invention] Technical field This invention is a system for printing newspapers, magazines, etc. in large quantities on a regular basis, and placing them on the top of printed materials that are continuously divided into bundles of the required number of copies to facilitate packaging and shipping. When the controlled address paper is updated in response to changes in a large number of address information, printed sequentially by an address paper printing machine, and then ejected continuously, and during the transportation and transshipment of large bundles of printed matter, where minutes and seconds matter. To make identification easier, select the desired color band and apply it to the designated position on the address paper.
This invention relates to an improvement of a color band printing device for printing address paper.

BACKGROUND ART Conventionally, an address printing machine selects in a predetermined order a large amount of address information including fixed information such as destination store name, number of copies to be shipped, date, number of pages, shipping route, code, etc. and variable information, such as Japanese Industrial Standards. After sequentially printing on size 4 paper in row A, both sides of the printed address paper are held between two flat belts and the paper is transported and discharged. A color band printing device that prints a color band is known. However, in such a conventional color band printing device, a color band roller that is lowered by a flat belt toward the address paper being conveyed presses the address paper and prints a strip of the desired color on it. When coating and printing,
The color band printed on the address paper is not of a constant width, and at the beginning of application, excessive ink is transferred, so it may be printed partially spread out on both sides of the band, or the color band may not be of a constant width. There was a drawback that the color became a striped pattern of shading in the longitudinal direction.

Purpose This invention overcomes the drawbacks of the conventional color band printing device described above, prints address information, and lowers the color band roller of the desired color to a predetermined position on the address paper as necessary during transportation. It is an object of the present invention to provide a color band printing device for a new address paper printing machine capable of beautifully printing a color band of a constant width without causing width unevenness or color unevenness.

Composition This invention consists of a support member that is disposed on the machine frame above the address paper conveyance path and is moved up and down by a drive member, and a support member that is attached to the support member in a horizontal direction perpendicular to the address paper conveyance direction. A hollow shaft is attached to the ink tank at its end and is movable up and down along a vertical groove formed in the support member. An ink roller is rotatably attached to a member and is supplied with colored ink from a hollow shaft, and below this ink roller,
A color band roller is rotatably attached to the support member in parallel with the ink roller, and whose central axis is movable up and down along a groove formed in the support member in an upward and downward direction, and the support member is in a raised position. When the color band roller is separated from the conveyed address paper, the ink roller is separated from the color band roller, and the support member is lowered by the drive member.
When the color band roller comes into contact with the top surface of the address paper, the color band roller rises relative to the support member, comes into contact with the ink roller, and pushes the ink roller upward. It is characterized by this.

This invention will be explained in more detail below based on embodiments shown in the drawings.

Reference numeral 1 shows the entire color band printing device for address paper according to this invention, and on the top of the machine frame 9 of the color band sorting device installed adjacent to the address paper printing machine (not shown),
It is held by an L-shaped holder 8 secured with bolts 10. 2 is a support device, and ink roller 1
7 and a color band roller 32, and is screwed to a piston rod 4 of a pneumatic cylinder 3 mounted on a holder 8 with a nut 5. 6 is support 2
The lower end of the guide rod is screwed into the support 2 and fixed with a nut 7, and when the support 2 moves up and down due to the operation of the pneumatic cylinder 3, the support 2
This guides the guide while preventing its rotation. The ink roller 17 is made by winding a material impregnated with ink, such as sponge or felt, in a cylindrical shape around a hollow core 18.
A large number of small through holes are provided with through grooves 19, and a hollow shaft 20 in the form of a steel tube is loosely fitted into the center hole of the hollow core metal 18, and the ink roller 17 is a hollow shaft that rests together with the hollow core metal 18. It rotates on the outer periphery of the shaft 20. The hollow shaft 20 is provided with two to three through grooves 22 extending in the axial direction at equal intervals on the circumference. Elbows 23 and 25 are fixed to both ends of the hollow shaft 20, and a flexible tube 24 extending from the discharge port of an ink pump provided in the machine frame 9 is connected to the elbow 23.
Similarly, a flexible tube 26 for returning ink to an ink tank provided within the machine frame 9 is connected to 5.

As shown in FIG. 3, the hollow shaft 20 is inserted into the groove 40 of the side plate 28 fixed to both sides of the support 2 with bolts 41.
It is fitted inside and can move slightly up and down. Reference numeral 29 represents a presser plate fixed to the upper surface of the side plate 28 with bolts 30 across this groove 40, and 27 represents a collar for positioning the ink roller 17 in the axial direction. When replacing the sponge of the ink roller 17, remove the holding plate 29 and take it out. The colored belt roller 32 is made of rubber or plastic, and is tightly attached to the outer periphery of the core metal 31 in a cylindrical shape, and is attached to the support shaft 3 via a bearing 33.
4 is rotatably supported. The support shaft 34 is provided with parallel flat surfaces 35 at both ends thereof, and these flat surfaces 35, as shown in FIG.
The holding plate 37 is fitted into grooves 39 provided at the lower ends of both sides of the support 2, and is fixed to the support 2 with bolts 38 across the grooves 39. Bolts 36 are screwed into both end faces of the support shaft 34 with washers 42 in between, and position the support shaft 34 in the axial direction.Therefore, the color belt roller 32 is pivotally supported on the support 2 together with the support shaft 34. It is also possible to move up and down within the groove 39.

Although only one is shown in the figure, a plurality of color band printing devices equal to the number of colors to be applied are linearly arranged on the holder 8 at equal intervals along the transport direction F of the address paper A. Arranged.

Next, to explain the operation of the above-mentioned color band printing device, in the address paper printing machine, the address paper A on which a large number of address information has been selected and printed is stretched over the angle 12 fixed to the frame 9 of both machines, and then The sheets are held on both sides by a pair of left and right flat belts 15 and 16, which slide and circulate on a support plate 11 fastened at 13, and are conveyed in the direction of arrow F, and sorted into a discharge stacking box (not shown). and are accumulated sequentially. When transporting or transshipping large bundles of printed matter, in addition to printing letters and codes on the address paper, predetermined colors such as red, blue, green, etc. are printed on the address paper so that the transporter can instantly identify and select it. Select the desired color from among the colors and print the color band in a predetermined position. For this purpose, when the address paper A on which a color band is to be printed is conveyed by flat belts 15 and 16 and passes under the required color band printing device 1,
The pneumatic cylinder 3 is actuated by a signal from a detector (not shown), and as shown in FIG. The color band roller 32 presses the right side upper surface of the address paper A, which is placed on a wide flat belt 14 and runs on a wide flat belt 14 that circulates on the support plate 11 at the same speed, to form a predetermined color band. Transfer over length. After the transfer, the support 2 rises again, and the color band roller 32 returns to the standby position. Note that the colored ink sent from the ink tank in the machine frame 9 by the ink pump is transferred to the flexible tube 24 and the elbow 2.
3, enters the hollow hole 21 of the hollow shaft 20, a portion passes through the through groove 22, further passes through the small through hole 19 of the hollow core bar 18, and is soaked into the sponge from inside the ink roller 17, and the rest is soaked into the sponge from the inside of the ink roller 17. 25, flexible tube 26
The ink is returned to the ink tank through the In the standby position, as shown in FIG.
2 is lowered in the groove 39 by its own weight together with the support shaft 34 and is supported on the upper surface of the presser plate 37. Therefore, the outer periphery of the color band roller 32 is spaced a distance C from the outer periphery of the ink roller 17. Both rollers are stationary, but at the application position lowered by the pneumatic cylinder 3, due to the reaction force of the support plate 11,
The color band roller 32 moves upward within the groove 39 of the support 2 and comes into contact with the outer periphery of the ink roller 17.
The ink roller 17 also escapes slightly upward along the groove 40 and comes into contact with the color band roller 32 without receiving excessive contact pressure, and due to the running force of the flat belt 14, the color band roller 32 However, as shown in FIG. 2, the ink roller 17 rotating in the direction of arrow D and in contact with it also begins to rotate in the direction of arrow E due to the color band roller 32, and as a result, the color band roller 32 rotates in the direction of arrow E. Colored ink is supplied to the outer periphery,
A color band having a width corresponding to the width of the color band roller 32 is printed on the address paper A.

Effects As mentioned above, in the standby position, the ink roller and color band roller are stationary and separated from each other, and in the application position, they rotate relative to each other while maintaining appropriate contact pressure. However, since an appropriate amount of colored ink is supplied to the color band roller, when the ink roller and the color band roller are constantly in contact with each other, ink pools at the contact point, which is caused by downward pressure toward the address paper. This prevents excess ink from being applied beyond the width of the swath roller at the beginning of printing, causing excess ink to spill out onto the address paper, or causing color unevenness or fading along the length of the swath. This has the excellent effect of being able to print a beautiful color band with a constant width and a constant density without causing any color problems.
