Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a long object printing device that continuously prints the same pattern on a long object such as a long tape.

[Prior Art] As an example of a long article, when letters 3, etc. of the same pattern are continuously printed on the fabric portion 2 of a fastener tape 1 as shown in FIG. 6, offset printing is used. Was.

To explain this with reference to FIG. 7, a plurality of rolls 4, 5,
Ink is applied to the circumferential surface of the first roll 4 of the rolls 6 in the shape of the characters 3 to be printed, and this ink is sequentially transferred to the circumferential surfaces of the rolls 5 and 6. The fabric portion 2 was sandwiched between the roll 6 and the fabric portion 7, and printing was performed on the fabric portion 2 from the roll 6.

[Problems to be solved by the invention] In the conventional printing method shown in FIG. There was a problem that the ink smeared during the transfer to 5 and 6, making it impossible to print clearly.

It is an object of the present invention to solve these conventional problems and provide a printing device for printing long objects that can print clearly with little ink scattering even when rotating at high speeds.

[Means for Solving the Problems] The present invention provides a receiving roll for moving a long object along its circumferential surface, and a receiving roll that has a hollow portion inside and a peripheral surface that moves the long object along the circumferential surface of the receiving roll. a stamp roll that is pressed against a surface; typed characters are provided protruding from the surface side so that the typed characters protrude from the circumferential surface of the stamp roll, and
A type body made of porous breathable metal that is removably attached to the stamp roll, a plating layer applied to the surface side of the type body excluding the part of the type, and connected to the hollow part of the stamp roll. an ink supply path provided in the stamp roll, and a communication path provided in the stamp roll that communicates the hollow portion with the back surface of the typeface;
This is a long article printing apparatus characterized by comprising:

[Function] The ink supplied from the ink supply path to the hollow part inside the stamp roll passes through the communication path, reaches the back of the type body, and oozes out onto the type part of the surface of the type body made of porous breathable metal. , printed on long objects. Furthermore, when changing the characters to be printed, the typeface is removed and replaced with another typeface.

[Example] Next, an example in which characters of the same pattern are continuously printed on the fabric portion of a fastener tape as a long article will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 8 denotes a receiving roll, the center shaft 9 of which is rotatably supported by a bearing 10, and is rotated clockwise at a constant speed in FIG. 1 by a rotation drive device (not shown). It is designed to be rotated. The fastener tape 1 guided by the guide rolls 11, 11 is in contact with the upper half of the circumferential surface of the receiving roll 8, and as the receiving roll 8 rotates, the fastener tape 1 is brought into contact with the upper half of the circumferential surface of the receiving roll 8. along the same line, to the right in FIG. As shown in FIG. 2, grooves 12 and 13 are provided on the circumferential surfaces of the receiving roll 8 and the guide roll 11 so that the interlocking portions of the fastener tape 1 can escape. Note that the groove 1 of the receiving roll 8
It is effective if the circumferential surface 2 is made of an elastic material such as rubber because it absorbs the pressure of the stamp roll 14.

A stamp roll 14 is provided directly above the receiving roll 8, and a hollow portion 15 is formed in the center of the stamp roll 14. This hollow portion 15 is closed by a lid 17 attached with screws 16. The stamp roll 14 is fixed to a boss portion 19 of a shaft 18 with a bolt 20, and is rotatably supported together with the shaft 18 by a bearing 21. Bearing 21
is attached to a swing arm 24 which is pivotally connected to the base 22 with a pin 23 (see FIG. 1). A spring 25 is provided between the end of the swinging arm 24 and the protrusion of the base 22, and the stamp roll 1
The circumferential surface of 4 is pressed against the circumferential surface of a receiving roll 8 with the fastener tape 1 interposed therebetween. 26 is an adjustment screw that changes the pressing force, and 27 is a stopper whose position can be adjusted.

A type body 28 is attached to the circumferential surface of the stamp roll 14. The typeface 28 is
A slurry made by mixing stainless steel powder, boron or metal boride, and a binder that evaporates during the drying and solidifying process is poured into a mold and solidified while being vibrated, and after drying, it is sintered in a vacuum. , made of porous breathable metal. As shown in FIGS. 3 and 4, the typeface 28 has typefaces 29 protruding from the front side to be printed, and the face side of the typeface 28 excluding the typefaces 29 is covered with chrome A plating layer 30 such as the above is applied. Further, a recess 31 is formed on the back surface of the type body 28.
A mounting hole 32 is provided in the type body 28, and the type body 28 can be attached to the circumferential surface of the stamp roll 14 by means of a screw 33 inserted through the mounting hole 32, as shown in FIG. At this time, the typeface 28
The printed characters 29 are designed to protrude from the circumferential surface of the stamp roll 14.

A communication path 34 is provided inside the stamp roll 14 to communicate the hollow portion 15 with the back surface of the type body 29. And Figures 1 and 2
Ink tank 35 and stamp roll 14 shown in the figure
Between the hollow part 15 and the metal tube 36, the flexible tube 3
7. An ink supply path constituted by a nipple 38 and a hole 39 in the lid 17 is provided to supply ink in the ink tank 35 to the hollow portion 15. The ink supplied to the hollow 15 passes through the communication path 34 and enters the recess 31 on the back side of the type body 28.
(See FIG. 5) and seeps into the type 29 portion of the type body 28 made of porous, air-permeable metal.

When the receiving roll 8 is rotated in the long material printing apparatus described above and the fastener tape 1, which is a long material, is moved along the upper half of the circumference of the receiving roll 8 as shown in FIG. The stamp roll 14 that is in pressure contact also rotates. ink tank 35
The ink being supplied to the hollow part 15 from the metal tube 36, the flexible tube 37, the nipple 38, and the hole 39 (see FIG. 2) generates centrifugal force due to the rotation of the stamp roll 14, and flows through the communication path 34, It passes through the recesses 31 of the type body 28 (see FIG. 5) and oozes out into the type 29 portion of the type body 28, thereby printing the character 3 on the fabric portion 2 of the fastener tape 1 (see FIG. 6). . As shown in FIG. 4, the surface side of the type body 28 is coated with a plating layer 30 except for the type 29 area, so that ink seeps out from the type 29 area and is not transferred to other rolls. Because it prints directly on the fabric part 2 of the fastener tape 1,
Character 3 is printed clearly without blurring, and the ink does not scatter around.

If the characters to be printed are to be changed, the screws 33 shown in FIG. 5 can be removed and the printed characters 28 can be replaced with other printed characters 28 having protruding characters 29. If printing is not performed for a long period of time, the ink inside the porous breathable metal that makes up the type body 28 will harden, but if the type body 28 is heated to 100 to 200 degrees Celsius, it will solidify. The ink burns off and new ink oozes out again.

[Effects of the invention] With this invention, when printing the same pattern on a long object in succession, the ink oozes out from the type and is printed directly on the long object, making it possible to print clearly. This has the effect of preventing ink from scattering around. In addition, since the typeface can be replaced, maintenance of the typeface is easy, and various typefaces can be printed on long objects, making it possible to create a long object printing device suitable for high-mix, low-volume production. can be provided.
