  Embodiments according to the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1 and 2, the number printing apparatus 100 is for printing serial numbers on a sheet 1 to be printed. For example, a print target portion 90 (for example, a banknote or a lottery ticket) is printed on one sheet 1 (see FIG. 17). In the sheet 1, print target portions 90 are arranged in a matrix of 4 columns and 5 rows. The number printing apparatus 100 includes five numbering units 10 for printing one row 90A (see FIG. 17) in which five print target portions 90 are arranged, an attachment ring 32 for fixing the numbering unit 10, and ink. And the inking roller 34. In order to print one column 90A for five columns, five configurations similar to the above are arranged. The five numbering devices 10 print one row 90A of the print target portion 90. The numbering unit 30 is composed of five numbering units 10.

  The five numbering devices 10 are arranged around the drive shaft 31 via the attachment ring 32. The attachment ring 32 is fixed to the surface of the drive shaft 31 concentrically with the drive shaft 31. The numbering device 10 is radially arranged by the mounting ring 32 in the radial direction of the drive shaft 31.

  A stopper 32a is formed along the outer periphery of the mounting ring 32 on the fixed gear 33 side. The stopper 32 a engages with a claw portion 11 a formed at one end portion of the bottom plate 11 of the numbering device 10. A claw portion 11 b formed at the other end of the bottom plate 11 engages with a claw 35 a of the fastening plate 35. The bottom plate 11 of the numbering device 10 is fixed to the mounting ring 32 with bolts 36 by a fastening plate 35. Thereby, the numberer 10 is fixed to the mounting ring 32. The numberer 10 is fixed to the drive shaft 31 via the attachment ring 32. The drive shaft 31 is driven by the drive unit 6 (see FIG. 7) and rotates around the axis L.

  A fixed gear 33 that functions as a sun gear is disposed so as to be concentric with the drive shaft 31. The fixed gear 33 is juxtaposed with the mounting ring 32. The fixed gear 33 is formed with a cam groove 33a extending around the axis L on the side surface on the numbering device 10 side. A part of the cam groove 33a is formed with a deformed portion 33b in which the groove protrudes in the radial direction. A roller 21 provided at the tip of the release lever 20 provided on the fixed gear 33 side of the numbering device 10 is arranged along the cam groove 33a. As will be described later, the roller 21 travels along the cam groove 33a as the drive shaft 31 rotates.

  The drive shaft 31 and the mounting ring 32 rotate relative to the fixed gear 33 in conjunction with each other. Thereby, when the drive shaft 31 rotates, the numbering unit 30 rotates in conjunction with it. The numbering unit 30 comes into contact with the thickening roller 34 at the top by rotation, and the ink adheres to the typeface P of the numbering unit 10 described later. The numbering unit 30 then prints serial numbers on the sheet 1 arranged on the impression cylinder 3 below by rotation.

  As shown in FIGS. 3 to 5, the numberer 10 includes a frame 15, a type ring unit 50 in which a plurality of type rings W for printing numbers is arranged, and a center axis X around the type ring W. It mainly includes a detection unit 16 that detects the position of the arranged type surface P, a plurality of lock poles 13 for stopping and releasing the rotation of the type wheel W, and a plurality of solenoids 18 that operate the lock pole 13. .

  The bottom plate 11 of the frame 15 is curved along the outer periphery of the mounting ring 32 (see FIG. 2). Claw portions 11 a and 11 b are formed on both side surfaces of the bottom plate 11 so as to extend. On both sides of the bottom plate 11, side plates 15 a and 15 b of the frame 15 are provided upright. U-shaped notches 15c and 15d are formed on the upper portions of the side plates 15a and 15b. The bearings B1 and B2 of the type ring unit 50 are fitted into the notches 15c and 15d from above.

  Above the type ring unit 50, the bracket 40 is fixed to the side plates 15a and 15b with screws 45 and 46 in order to prevent the bearings B1 and B2 from falling off. In the bracket 40, a leaf spring 42 is overlaid on the bracket body 41. The leaf spring 42 has arm portions 43 and 44 at both ends. The tips 43a and 44a of the arm portions 43 and 44 are jumped upward. When the bracket body 41 and the leaf spring 42 are fastened together with the side plates 15a and 15b with the screws 45 and 46, the tips 43a and 44a press the bearings B1 and B2 of the type ring unit 50 from above.

  The type ring unit 50 includes a shaft 51, a type ring group 12 including a plurality of type rings W into which the shaft 51 is inserted, bearings B1 and B2 that pivotally support both sides of the type ring group 12, and one end of the shaft 51. A numbering device driving gear 52 formed concentrically with the shaft 51 is provided. An intermediate gear 53 provided on the fixed gear 33 side of the side plate 15a meshes with the numbering device driving gear 52. The intermediate gear 53 is rotatably supported on the side plate 15a.

  A drive gear 54 is provided concentrically with the intermediate gear 53 on the fixed gear 33 side of the intermediate gear 53. The drive gear 54 meshes with the fixed gear 33 (see FIGS. 1 and 2). As a result, when the numbering unit 30 rotates around the drive shaft 31, the drive gear 54 becomes a planetary gear with respect to the fixed gear 33 and revolves around the fixed gear 33. Accordingly, the intermediate gear 53 rotates in conjunction with the rotation of the drive gear 54, and the driving force is transmitted from the intermediate gear 53 to the numbering device drive gear 52 to rotate. The shaft 51 is rotated by the rotation of the numbering device driving gear 52.

  The type ring group 12 is inserted into the shaft 51. In the type ring group 12, type rings W of 1 to n digits (n = 11 in this embodiment) of numbers to be printed are arranged. Each type ring W is rotatable with respect to the shaft 51. There is friction between the shaft 51 and the type ring W, and when the shaft 51 rotates, the type ring W rotates in conjunction with the shaft 51 by this friction. The type ring W includes various types for printing numbers such as numbers, alphabets, and symbols. The type ring group 12 includes a combination of various type rings W.

  The type ring W has twelve type surfaces P in which the type inverted in the circumferential direction is formed in a convex shape. The type face P is printed with numbers on a printed matter when the type ring W is rotated. Twelve concave portions R are formed between the twelve typefaces P. The concave portion R is provided with seven magnet arrangement portions M on which columnar magnets G are arranged. The seven magnet arrangement parts M include an N magnetic pole arrangement part MN in which N magnetic pole magnets are arranged, and an S magnetic pole arrangement part MS in which S magnetic pole magnets are arranged (see FIGS. 8B to 15). As the magnet G, for example, a neodymium magnet is used. The other concave portion R has five portions where the magnet G is not disposed, and this is referred to as a non-arranged portion F. The arrangement of the magnet G of the type ring W will be described in detail later.

  In order to detect the magnet G of the type ring W, a detection unit 16 is provided in the frame 15. The detection unit 16 includes a plurality of sensor units 16A corresponding to the type rings W, respectively. The sensor unit 16A is provided with three sensors 16a, 16b, and 16c for detecting the presence or absence of the magnet G so as to face the positions of the three recesses R adjacent to the circumferential direction of the type wheel W. . The sensors 16a, 16b, and 16c are magnetic sensors such as Hall elements. When the detection results of the sensors 16a, 16b, and 16c are used, the position of the typeface P of the type ring W is specified.

  On one side of the type ring W, twelve claw teeth Wa formed radially from the central axis X corresponding to the type surface P are formed. The tip 13a of the lock pole 13 for stopping the rotation of the type ring W is meshed between some of the claw teeth Wa and the claw teeth Wa (see FIG. 6). The plurality of lock poles 13 are arranged below the type ring unit 50. The front ends 13a of the plurality of lock poles 13 are inserted between the type ring W and the type ring W of the type ring group 12 and mesh with the claw teeth Wa.

  The lock pole 13 rotates within a limited range around the shaft 26. The rotation operation of the lock pole 13 is controlled by a solenoid 18. As the plunger 18a of the solenoid 18 expands and contracts, the lock pole 13 rotates within a limited range. And the front-end | tip 13a repeats engagement and cancellation | release with respect to the nail | claw tooth Wa. The lower end of the lock pole 13 is in contact with the distal end of a leaf spring 24 for releasing the distal end 13a from the claw tooth Wa.

  The distal ends of the leaf springs 24 are branched into a plurality so as to simultaneously press the lower ends of the plurality of lock poles 13. The leaf spring 24 is provided on the spring holder 23. The shaft 22 is inserted through the spring holder 23. The shaft 22 is pivotally supported by the side plates 15a and 15b. A release lever 20 for rotating the spring holder 23 is provided at one end of the shaft 22 on the fixed gear 33 side. A roller 21 is rotatably provided at the tip of the release lever 20. In the shaft 22, a cam sensor plate 28 for detecting the rotation of the release lever 20 is provided between the spring holder 23 and the side plate 15 a. When the cam sensor plate 28 rotates in conjunction with the rotation of the shaft 22, the cam sensor 29 detects this rotation.

  The spring holder 23 rotates in conjunction with the rotation of the release lever 20. By the rotation of the spring holder 23, the leaf spring 24 can simultaneously press the lower ends 13b of the plurality of lock poles 13.

  As shown in FIG. 6, the lock pole 13 is composed of an obtuse V-shaped blade. The lock pole 13 rotates within a limited range around the shaft 26 disposed at the center. A locking claw 14 is formed at the tip 13 a of the lock pole 13. The locking claw 14 meshes with a claw tooth Wa formed on the side surface of the type ring W. As a result, the lock pole 13 is constrained with respect to the type ring W, and the rotation of the type ring W is restricted.

  The lock pole 13 is provided with a spring 19 for applying a back tension in order to maintain a restrained state with respect to the type wheel W. The position of the spring 19 is not limited to the illustrated location, and may be disposed at another location. For example, the back tension may be applied to the lock pole 13 by pulling the spring 19.

  A leaf spring 24 is in contact with the lower end 13 b of the lock pole 13. When the lower end 13 b is pressed against the leaf spring 24, the lock pole 13 rotates about the shaft 26. Then, the locking claw 14 is released from the claw tooth Wa. At this time, the lock pole 13 is released from the type ring W, and the type ring W is rotatable.

  The rotation of the lock pole 13 is controlled by a solenoid 18 connected to a position A near the tip 13a or a position B near the lower end 13b. The solenoid 18 is disposed with brackets 47 and 48 at the position A or the position B so as not to interfere with the adjacent lock pole 13 (see FIG. 4). The solenoid 18 includes a coil 18b that generates a magnetic field, a metal plunger 18a that is movable with respect to the coil 18b, and a permanent magnet 18c that attracts and holds the plunger 18a toward the coil 18b.

  In the solenoid 18 in a state where the coil 18b is not energized, the plunger 18a is magnetically attracted to the permanent magnet 18c, and the lock pole 13 is released from the type wheel W. When a pulse current is supplied to the coil 18b, a magnetic field in a direction opposite to the magnetic field of the permanent magnet 18c is generated by the eddy current flowing in the plunger 18a, and the plunger 18a is released from the permanent magnet 18c. At this time, the lock pole 13 is urged by the spring 19 to rotate.

  Then, the tip 13 a meshes with the claw tooth Wa, and the lock pole 13 is in a restrained state with respect to the type wheel W. At this time, the plunger 18a moves in a direction extending with respect to the coil 18b. In this state, the permanent magnet 18c does not have a magnetic force until the plunger 18a is attracted.

  Therefore, it is not necessary to energize the coil 18b while maintaining the released state and the restrained state of the lock pole 13 with respect to the type wheel W. That is, only when the plunger 18a is released from the permanent magnet 18c, a pulse current needs to be applied to the coil 18b, and the numbering device 10 can save power. In order to change the type surface P of the type ring W, the plunger 18a needs to be attracted again to the permanent magnet 18c side, and the lock pole 13 needs to be released from the type ring W.

  Therefore, the lower end 13b of the lock pole 13 is pressed by the leaf spring 24 provided on the spring holder 23, and the lock pole 13 is rotated. The spring holder 23 rotates in conjunction with the operation of the release lever 20. The release lever 20 operates by traveling of a roller 21 provided at the tip of the release lever 20. The roller 21 travels along a cam groove 33a provided in the fixed gear 33 (see FIGS. 1 and 2). When the roller 21 travels on the deforming portion 33b provided in a part of the cam groove 33a, the release lever 20 rotates around the shaft 22.

  The plurality of lock poles 13 are simultaneously released from the type wheel W. After printing on the printing target portion 90 by the numbering device 10, the roller 21 travels through the deforming portion 33b (see FIG. 1). After the lock pole 13 is released with respect to the type ring W, the numbering unit 10 is arranged in the type ring group 12 in order to print the next print target portion 90 before reaching the filling roller 34. Further, it is necessary to control so that the typefaces P of the plurality of typewheels W come to predetermined positions.

  As shown in the block diagram of FIG. 7, the numbering device 10 includes a cam sensor 29 that detects the rotation of the release lever 20 and a control unit 5 that controls the plurality of solenoids 18. The cam sensor 29 detects the rotation of the release lever 20 by the cam sensor plate 28. The cam sensor 29 transmits a cam detection signal to the control unit 5. The control unit 5 is realized by an MPU, for example. When receiving the cam detection signal from the cam sensor 29, the controller 5 starts controlling the solenoid 18b. The control unit 5 controls the solenoid 18 based on the arrangement pattern of the magnet G of the type ring W detected by the sensors 16a, 16b, and 16c, and aligns the characters of the 1-n digit type ring W in a predetermined arrangement.

  The numberer 10 includes an external controller 7 for confirming whether the characters on the type ring W are in a predetermined arrangement and stopping the driving unit 6 when an arrangement error is detected. Hereinafter, the operation of each block will be described together with the description of the operation of the number printing apparatus 100.

  The state in which the plurality of lock poles 13 are simultaneously released from the type wheel W by the release lever 20 is set as the starting point of the number printing cycle. When the drive shaft 31 is driven by the drive unit 6, the numbering unit 30 composed of a plurality of numbering devices 10 on the attachment ring 32 rotates in conjunction with the drive shaft 31. At this time, the drive gear 54 meshed with the fixed gear 33 revolves around the fixed gear 33. The drive gear 54 rotates (spins) by the revolution of the drive gear 54. The rotation of the drive gear 54 is transmitted to the numbering drive gear 52 via the intermediate gear 53.

  When the numbering device driving gear 52 rotates, the shaft 51 rotates in conjunction with it. At this time, the type rings W arranged in 1 to n digits are rotated by friction with the shaft 51 in conjunction with the rotation of the shaft 51. The cam sensor 29 detects the rotation of the release lever 20 after the roller 21 travels through the deforming portion 33b provided in a part of the cam groove 33a. The cam sensor 29 transmits a cam detection signal to the control unit 5. The control unit 5 starts controlling the solenoid 18 by receiving the cam detection signal. The detection part 16 detects the magnet G arrange | positioned at the type ring W by sensor 16a, 16b, 16c. The control part 5 identifies the character of the type face P of each type ring W based on a detection result. The control unit 5 causes a pulse current to flow through the solenoid 18 of each lock pole 13 corresponding to the type ring W in order to arrange the type face P of the type ring group 12 in a desired character string.

  As a result, the lock pole 13 is in a restrained state with respect to the type ring W, and the rotation of the type ring W stops. In this state, the shaft 51 is in a state of sliding and rotating with respect to the type wheel W. Thereby, the control part 5 arranges the typeface P of the type ring group 12 in a desired character string until the numbering unit 30 reaches the inking roller 34.

  Before the numbering unit 30 passes the meat roller 34, the external controller 7 sets the typeface of the typering W of the typering group 12 to each control unit 5 of each numbering unit 10 of the numbering unit 30.
