The moving unit 70 moves between the alignment unit 30 and the printing unit 40 in response to the arrangement of the alignment unit 30 and the printing unit 40, and holds the aligned writing instrument P to the printing unit 40. ) can be supplied.

Referring to FIGS. 1, 8, and 9, the printing unit 40 includes a rotating plate 41, a plurality of seating frames 42, and a stamp unit 43.

The rotating plate 41 is a plate-shaped member and can rotate intermittently by the driving device 41a coupled to the lower part. Although the rotating plate 41 is shown in the drawing as being formed in a disk shape, it is not limited to this, and the shape of the rotating plate 41 may be modified in various ways. On the upper surface of the rotating plate 41, a plurality of seating frames 42 are arranged to be spaced apart from each other in the circumferential direction of the rotating plate 41.

The seating frame 42 is for fixing the writing instrument (P), and may have at least one indented groove (42a) formed on its upper surface to accommodate the writing instrument (P). More specifically, a pair of indented grooves (42a) are formed side by side on the upper surface of the seating frame 42 to accommodate a pair of writing instruments (P) at the same time, and each indented groove (42a) is connected to the clip portion (P3). is formed in the shape of a writing instrument (P) biased to one side, but both sides overlapping with the body portion (P2) may be formed to be open outward. Since both sides of the indented groove 42a are formed open to the outside, the separation portion 52, which will be described later, can easily grasp and separate the writing instrument P inserted in the indented groove 42a. When the moving part 70 places the writing instrument (P) on the seating frame 42, the rotating plate 41 rotates intermittently, and when the rotating plate 41 stops rotating, the pressing portion 44 descends and the writing instrument ( P) can be pressed and inserted into the indented groove (42a). The pressing part 44 is coupled to one side of the rotating plate 41 to be able to be lifted up and down in the vertical direction, and can be lifted up and down again after pressing the writing instrument P. When the pressing part 44 presses the writing instrument P and inserts it into the indented groove 42a, the rotating plate 41 rotates intermittently, and when the rotating plate 41 stops rotating, the stamp section 43 is attached to the seating frame. The writing instrument (P) accommodated in (42) can be stamped and printed. The stamp unit 43 can be lifted and lowered in the vertical direction by the cylinder device 431 connected to the top, and the cylinder device 431 can slide in the horizontal direction by the sliding member 432.

More specifically, the stamp unit 43 is lowered by the cylinder device 431 and contacts the printing plate 433, as shown in (a) of FIG. 9, before the writing instrument P reaches the printing position. can do. For example, the printing plate 433 is filled with ink, and the pattern or phrase to be printed on the writing instrument P is engraved in an embossed or engraved form on the lower surface of the stamp portion 43, so the stamp portion 43 is printed. When the original plate 433 is contacted, ink may be deposited on the lower surface on which a pattern or phrase is engraved. However, it is not limited to the fact that the printing plate 433 is filled with ink and the pattern or phrase is engraved in an embossed or engraved form on the lower surface of the stamp portion 43, and can be modified in various ways to have a printable structure. For example, when the printing plate 433 is filled with ink while a pattern or phrase is engraved in an embossed or engraved form, and the stamp portion 43 contacts the printing plate 433, it is printed on the lower surface of the stamp portion 43. The pattern or phrase engraved on the original plate 433 may be stained. The stamp part 43 is raised by the cylinder device 431 in an ink-covered state, and simultaneously or sequentially, as shown in (b) of FIG. 9, is moved to the seating frame 42 by the sliding member 432. You can slide forward toward . When the stamp portion 43 slides and is disposed to overlap the writing instrument P to be printed, as shown in (c) of FIG. 9, the stamp portion 43 is lowered by the cylinder device 431 to print the writing instrument P ) can be printed by inking at least one of the body portion (P2) and the clip portion (P3). When the stamp unit 43 stamps and prints the writing instrument P, the elastic pressing unit 45 can apply elastic force to the writing instrument P to secure the writing instrument P. When the stamp unit 43 stamps and prints the writing instrument P, the elastic pressing unit 45 can apply elastic force to the writing instrument P to secure the writing instrument P. At the moment when the stamp unit 43 stamps the writing instrument P or returns to its original position after stamping the writing instrument P, the writing instrument P may move or suddenly be separated from the indented groove 42a. If the writing instrument (P) moves or is suddenly separated from the indented groove (42a), printing may not be performed properly, the printed ink may spread and defects may occur, and the device may not operate smoothly due to the separated writing instrument (P). The elastic pressing portion 45 is designed to prevent this problem, and is coupled to one side of the rotating plate 41 to enable lifting and lowering, and can intermittently apply elastic force to the writing instrument P.

Although not shown in the drawing, when printing is completed, the stamp unit 43 rises again by the cylinder device 431 and slides backwards by the sliding member 432, so that the above-described series of processes can be repeated. there is.

Referring again to FIGS. 1 and 8 , the writing instrument P on which printing has been completed in the printing unit 40 may be discharged by the discharge unit 50 . The discharge unit 50 may include a transfer unit 51 and a separation unit 52.

The transfer unit 51 is formed in a conveyor structure to transfer the printed writing instrument (P) in the horizontal direction, and includes a pair of belt pulleys 511 arranged in parallel and spaced apart from each other, and a pair of belt pulleys 511 ) may include a conveyor belt 512 that is connected to each other and circulates to form a closed loop, and a motor (not shown) that rotates at least one of the pair of belt pulleys 511. If necessary, a separate screen (not shown) may be installed on at least one side of the conveyor belt 512 to prevent the writing instrument P from leaving, and a drying device (not shown) is provided to dry the ink. It could be. Since the transfer unit 51 is a typical conveyor, detailed description of its structure and operation will be omitted.

The separation unit 52 separates the writing instrument P inserted into the indented groove 42a from the seating frame 42 and seats it on the transfer unit 51, and is capable of lifting and lowering in the vertical direction and sliding in the horizontal direction at the same time. It can be formed into a structure. That is, the separator 52 descends toward the seating frame 42, simultaneously grasps a pair of printed writing instruments (P), and then rises again to slide in the horizontal direction toward the transfer unit 51 and transfer unit 51. ), it can descend again and place the writing instrument (P) on the conveyor belt 512 of the transfer unit 51. The separator 52 slides along the rail 53 coupled to the main body 60 and can be held by applying pressure from both sides of the writing instrument P to prevent ink from spreading.
