Description

[Detailed description of the invention]

The present invention relates to a numbering device with check digits for a rotary press, which is used to continuously print code numbers with check digits on sheets of paper that are attached to the rotary press and fed. In a series of patent applications represented by Japanese Patent Application No. 52-130405, the inventor of the present application has developed a check digit consisting of a one-digit number corresponding to a code number obtained by arbitrary weighting of modulus 10 or modulus 11. We proposed a numbering device that prints out the code number. These series of numbering devices are characterized by a mechanical mechanism that responds to changes in code numbers by printing out check digits that follow a predetermined cyclic number arrangement, and are mounted directly on the rotating shaft of a rotary press. This makes it possible to print out a code number with a check digit. However, if the numbering device is attached to the rotating shaft of a rotary press, the printing force due to contact with the impression cylinder of the rotary press will be directly applied to the printing unit of the numbering device, and continuous printing will be performed due to high speed rotation. The shock was great,
The drive control section of the check digit type wheel had a complicated mechanism and could not withstand use in a rotary press. Further, in rotary presses, a plurality of numbering devices are usually mounted radially on the rotary shaft to print a plurality of code numbers in one rotation, and sufficient research has not been conducted on the mechanism for this purpose. An object of the present invention is to provide a rotary press with a robust structure that has a mechanism that can withstand use in a rotary press, and also to enable a plurality of numbering devices to be attached to the same rotating shaft by using a known skip wheel. The present invention provides a numbering device for Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention in which a check digit with arbitrary weighting in modulus 10 is printed together with a code number. In FIG. 1, a printing unit 10 is rotatably mounted on a fixed shaft 16 fixed to a frame 14 together with a check digit type wheel 12.
A shaft 18 rotatably mounted on the frame 14 in parallel with the fixed shaft 16 is provided with a ratchet wheel group 20 corresponding to the printing unit 10 and the check digit type wheel 12, and this portion is connected to a second wheel.
It is extracted and shown in the figure. In FIG. 2, the printing unit 10 has six numbering type wheels 2 corresponding to the six digits of the code number.

F, each numbering type wheel 22A-22F
A driven gear 24 is integrally provided to each of the. A driven gear 24 is also integrally provided to the check digit type wheel 12. On the other hand, the ratchet wheel group 20 has a numbering type wheel 22A-

are provided integrally. Similarly, a ratchet wheel 30 is mounted integrally with a drive gear 28 on the shaft 18 in correspondence with the check digit type wheel 12. The ratio of the number of teeth between the driving gear 28 and the driven gear 24 is 1:1,
Numbering type wheels 22A-22F rotate synchronously with ratchet wheels 26A-26F. Ratchet wheel 30 and check digit type wheel 1
The same applies to 2. The check digit cyclic numeral arrangement provided on the check digit type wheel 12 will now be explained. The embodiment shown in FIG. 1 outputs a check digit with a modulus of 10, and the check digit with a modulus of 10 is determined by the weight attached to the lowest digit of the code number as shown in the table below.
A rotating number sequence of 1 is used.

[Table] In Table 1, "*2" represents a runes check, and "+1" indicates that the code number increases sequentially due to the printing operation, and "-1" indicates that the code number decreases sequentially. Furthermore, the weight 5 is not shown because the check digit is "0,5".
This is because the process is repeated frequently, which is disadvantageous for error checking. For example, modulus 10 weighted 1, 3, 7
Taking +1 as an example, the check digit type wheel 12 is provided with a circular numeric array ``0, 3, 6, 9, 2, 5, 8, 1, 4, 7'' of the array symbols in Table 1. It will be done. A numbering device equipped with a check digit type wheel 12 having this cyclic numeric arrangement can be used when only one device is mounted on the rotating shaft of a rotary press. However, in an actual rotary press, a plurality of numbering devices are usually attached to the rotating shaft, and in this case, the cyclic number arrangement of the check digit type wheel 12 changes depending on the number of numbering devices attached. In addition, a known skip wheel corresponding to the number of units installed is used as the ratchet wheel 26A for driving the numbering type wheel 22A of the least significant digit of the printing unit 10. Therefore, as shown in FIG. 3, taking as an example the case where three numbering devices 34 are installed radially around the rotating shaft 3, the printing unit 10,
The configuration of the check digit type wheel 12 and the ratchet wheel group 20 will be explained. In FIG. 3, 36 is a fixed cam for changing the code number of the numbering device 34, 38 is an ink roller, and 40 is an impression cylinder. First, as the ratchet wheel 26A for sending the least significant digit of the code number of the ratchet wheel group 20, a ratchet wheel having deep grooves 42 at three locations as shown in FIG. 4 is used. The numbering type wheel 22A of the lowest digit driven by this ratchet wheel 26A has "0, 1, 2...
The code number array ``0, 3, 6, 9, 2, 5, 8,
1, 4, 7" are arranged at equal intervals. The ratchet wheel 26A and numbering type wheel 22A of each of the numbering devices 34 No. 1 to No. 3 shown in FIG. 3 have the above-described configuration. The other ratchet wheels 26B-26F and numbering type wheels 22B-22F are constructed as shown in FIG. Next, the cyclic numeric arrangement of the check digit type wheel 12 used in the No. 1 to No. 3 numbering device 34 of FIG. 3 will be explained. Weight 1, 3,
The cyclic number arrangement when one numbering device was installed in No. 7 was the arrangement code "0369258147" from Table 1 above. However, as shown in Fig. 3, when three numbering devices 34 No. 1 to No. 3 are installed, the check digit changes every three times from the initial set check digit.
It becomes "0, 9, 8, 7, 6, 5, 4, 3, 2, 1". This corresponds to the cyclic numeral arrangement of the arrangement symbol A in Table 1, and when three numbering devices are installed, the cyclic numeral arrangement of the arrangement symbol A is used for the check digit type wheel 12. Next, No. 1 to No. 3 for changes in code number.
The following Table 2 shows the change in check digits in the numbering device.

[Table] In Table 2, the numbers in circles represent the number of check digit skips that occur at singular points when the code number is shifted. That is, No. 1 to No.
Table 3 below holds true for any of the numbering devices listed in Table 3.

[Table] The number of check digit skips at the singular point shown in Table 3 is predetermined according to the number of digits of the code number. Referring again to FIG. 1, the printing unit 10, check digit type wheel 12 and ratchet wheel group 2 shown in FIGS.
The structure of the numbering device of the present invention having 0 will be explained subsequently. A feed pawl mechanism 44 for intermittently rotating the numbering type wheel of the printing unit 10 is a horizontal rod 46 that is arranged parallel to the shaft 18 and is pivotally supported by a pair of pole arms 48 extending from both ends of the shaft 18.
It is pivoted by. This pole arm 48 has axis 1
It is rotatably attached to 8. Also horizontal rod 46
A horizontal rod 50 is pivotally supported by a pole arm 48 at the rear. Also, on the right side of the shaft 18 is a flange 5.
A drive arm 54 is implanted in the flange 52, and a roller 56 is rotatably supported at the tip of the drive arm 54. This roller 56
As shown in FIG. 3, is located on the side of the numbering device, and is swung in sliding contact with a cam 36 by the rotation of the rotary shaft 32 of the rotary press, and through the sliding contact between the cam 36 and the roller 56, the code number in the numbering device is displayed. changes will be brought about. The feed pawl mechanism 44 in FIG. 1 includes a repeat count setting pawl 60 that is engaged with a repeat count setting mechanism 58 provided on the shaft 18, and six pawls 44A, 44B, 44C, 44D of different lengths. 44E and 4
It has 4F. Each pawl 44A-44F is connected to a ratchet wheel 26A-44F shown in FIG.
26F, the pawl 44A engages with a ratchet wheel (skip wheel) 26A that drives the numbering type wheel 22A of the lowest digit. The other pawls 44B-44F are selectively engaged by the pawls falling into the deep grooves of the lower ratchet wheel as the lower ratchet wheel advances, thereby changing the adjacent upper ratchet wheel by one pitch. For example, when the pawl 44A falls into the deep groove of the ratchet wheel 26A as shown, the ratchet wheel 26B of the pawl 44B engages and the roller 56
Due to the rotation of the shaft 18 due to sliding contact, the claws 44A, 44B
The two ratchet wheels 26A, 2 engaged with
6B is fed one pitch at the same time, and as a result, the numbering type wheels 22A and 22B of the printing unit 10 rotate one pitch at the same time, and the code numbers start from 1st.
Moved to 10th place. The rotation angle of the feed claw mechanism 44 during this shift is as follows:
The depth of the carry provided in each of the ratchet wheels 26A-26F is determined so that the rotation angle increases successively. The amount of rotation of the shaft rod 46 by the feed pawl mechanism 44 during this digit feeding is determined by the ratch wheel 30 for detecting the singular point of the code number and for driving the check digit type wheel 12.
It plays an important role in idling the number of skips according to Table 3 above. A ratchet wheel 30 for driving the check digit type wheel 12, which is provided on the shaft 18 following the ratchet wheel group 20, is integrally provided with a pawl gear 62 having ten teeth. Can rotate independently from the et wheel group.
The ratchet wheel 30 is intermittently fed in synchronization with the ratchet wheel 26A in cases other than shifts that cause a singularity. This synchronous feed mechanism is
A feed pawl 64 with a pawl engaged with the ratchet wheel 30, and a feed pawl mechanism 4 connected to the feed pawl 64.
4, and a pole stopper 68 installed on the side of the feed claw mechanism 44. The center portion of the feed pole 64 is rotatably attached to the horizontal rod 46, and a tension spring 66 is interposed between the feed pole 64 and the pole stopper 68. Therefore, to explain the operation of this synchronization mechanism, when the feed pawl mechanism 44 rotates as shown by the broken line arrow due to the swing of the drive arm 54 due to the sliding contact of the roller 56 with the cam 36, the feed pawl 64 moves against the tension spring 66. energized by
Since the claw of the feed pole 64 is pressed against the ratchet wheel 30, the feed pole 64 rotates integrally with the feed claw mechanism 44, and the ratchet wheel 3
Sends 0 intermittently. This ratchet wheel 30
With intermittent feeding, numbering type wheel 2 of the lowest digit
2A, the check digit type wheel 12 is intermittently fed one pitch at a time. Next, a drive control mechanism for rotating the check digit type wheel 12 by a predetermined number of skips at a singular point when the code number is shifted will be explained. First, in order to idle the check digit type wheel 12, the feed pole 64 must be separated from the ratchet wheel 30.
The detachment mechanism for the feed pole 64 includes a pinion 70 fixed to the horizontal rod 46 and a pinion 72 rotatably attached to the horizontal rod 50 that meshes with the pinion 70.
and a control pin 74 implanted on the side surface of this pinion 72. During the shift, the amount of rotation of the feed pawl mechanism 44 increases in the direction of the dashed arrow, so the amount of rotation of the pinion 72 that meshes with the pinion 70 also increases, and the rear end of the feed pawl 64 is controlled by the control pin 74. is pushed up and feed pole 6
4 is removed from the ratchet wheel 30, and the check digit type wheel 12 is not fed synchronously with the numbering type wheel 22A. In addition, a drive source is required to idle the check digit type wheel 12, and the drive source causes the check digit type wheel 12 to rotate by a predetermined number of skips corresponding to the singularity of the code number. A rotation angle control mechanism is required to rotate the engine at idle. First, the drive source will be explained. A torsion spring 78 provided at the left end of the drive shaft 76 to which the ratchet wheel 30 is connected generates the drive force. One end of the torsion spring 78 is fixed to a flange 80 fixed to the left end of the drive shaft 76, and a cam wheel 84 having a cam portion 82 is locked to the other end of the torsion spring 78. This cam wheel 84 is connected to the torque setting spring 8
6 to a ratchet wheel 88 which acts as a torque limiter. A stopper pin 90 is implanted on the cam wheel 84 side of the ratchet wheel 88, and when the stopper pin 90 abuts against the cam portion 82, the cam wheel 70 is locked to the ratchet wheel 88. A pawl 92 is engaged with the pawl 88 , and this pawl 92 is supported on the peripheral side of a gear 94 and is engaged with the pawl 88 against the driving force of the torsion spring 78 . In addition, the ratchet wheel 88, the cam wheel 8
4 and the gear 94 are both rotatably mounted on the shaft 18. The gear 94 is an idle gear 96,
The drive gear 1 is connected to the gear shaft 100 via the gear shaft 98 and has the idle gear 98 fixed thereto.
02 is fixed. Therefore, the driving force accumulated in the torsion spring 78 is transferred to the gear 94 and the idle gear 9.
6, 98 and the drive gear 1 via the gear shaft 100.
02. When the ratchet wheel 30 is intermittently rotated by the feed pole 64, the torsion spring 78 is intermittently wound through the drive shaft 76, and a predetermined drive energy is accumulated. When the torsion spring 78 is wound more than necessary, the cam wheel 84 rotates in the same direction as the torsion spring 78 against the torque setting spring 86, and the cam part 82 sinks into the pawl 92 and pushes up, causing the pawl 92 to move against the pawl wheel 88. Remove from. Then, the ratchet wheel 8
8 is rotated by the reaction force of the torque setting spring 86, and the ratchet wheel 8
The stopper pin 90 of 8 is connected to the cam portion 82 of the cam wheel 84.
Rotation of the ratchet wheel 88 is stopped at the position where it comes into contact with.
This rotation of the ratchet wheel 88 releases the excess energy stored in the torsion spring 78 to the outside. Between the drive source having the above configuration and the ratchet wheel 30, in order to idle-rotate the check digit type wheel 12 according to the magnitude of the rotation angle of the feed pawl mechanism 44 at the singular point of the code number.
A rotation angle control mechanism is provided to control the rotation output angle from the drive source. This rotation angle control mechanism is
A starting control section that determines the starting point of the drive source including the aforementioned torsion spring 78 and transmits the driving force to the ratchet wheel 30 via the drive shaft 76, and a rotation angle control section that determines the magnitude of the rotation angle after starting. It is composed of First, the rotation angle control section controls a preset cam group 104 rotatably mounted on the drive shaft 76, a plurality of levers 106 selectively circumferentially attached to the preset cam group 104, and a plurality of levers 106 that selectively control the preset cam group 104. a plurality of selection cams 108 secured to the crossbar 46 for circumferentially surrounding one of the groups 104;
The drive system path of the preset cam group 104 includes a locking pawl 114 pivotally supported on the periphery of the preset cam group 104 that engages with a ratchet gear 112 fixed to a drive shaft 76 rotated by a drive source.
and a path for driving the preset cam group 104 from the drive gear 102 to the driven gear 110 for initializing the preset cam group 104 and further assisting the rotation of the preset cam group 104. The preset cam group 104 is connected to the printing unit 10.
Since there are 6 singular points, there are 6 preset cams, and the lever 106 corresponds to this number.
and a selection cam 108 are provided. Each cam in the preset cam group 104 has a protrusion on its outer periphery that acts as a stopper, and depending on the rotation angle between the claw at the tip of the lever 106 and this protrusion, the idle rotation angle is adjusted according to the number of check digit skips. is set. During digit feeding, which is the singularity of the code number, one of the levers 106 falls into the groove of the selection cam 108, and the claw at the tip of the selected lever 106 moves to the preset cam group 104.
An idle rotation angle at an arbitrary singular point circumferentially surrounding one of the points and corresponding to the number of skips is prepared. Also,
In this state, a driving force is applied to the preset cam group 104 through the driven gear 110 to urge the preset cam group 104 in the same direction as the idle rotation direction so that the preset cam group 104 can follow the rotation of the ratchet wheel 30 and pawl gear 62 by the drive shaft 76. I'm joining in. Next, the activation control section of the rotation angle control mechanism operates a stopper mechanism consisting of a pawl 116 and a stopper 118 that are rotatably mounted on the same shaft as the locking pawl 114, and a pawl gear 62 that is integrated into the ratchet wheel 30. A non-return claw 120 that prevents the back from returning, and the non-return claw 120 and the claw 116
It consists of a release cam 122 for releasing the engagement, and an attachment/detachment cam mechanism 124 for rotating the release cam 122. First, stopper 11 fixed to the frame
The pawl 116 that engages with the stopper 118 is coaxially attached to the peripheral edge of the preset cam group 104 with the same axis as the locking pawl 114.
The preset cam group 104 cannot be rotated unless it is removed. In addition, the locking claw 114 is connected to the drive shaft 76.
At the same time, the non-return pawl 12 against the pawl gear 62 is engaged with the ratchet gear 112 fixed to the
Unless the zero engagement is also released, the ratchet wheel 30 cannot be rotated by the drive shaft 76 together with the preset cam group 104. This nail 116
The detachment of the check claw 120 is caused by the rotation of the release cam 122 as the rotation angle of the feed claw mechanism 44 increases at the singular point of the code number. That is, this is done by operating a lever 126 installed on the release cam 122, and the claw 116 actually moves to the stopper 118.
The non-return claw 120 comes off before it comes off. The attachment/detachment cam mechanism 124 that operates the lever 126 of the detachment cam 122 includes a disk cam 128 having a protrusion on the side surface fixed to the horizontal rod 46, and a disk cam 128 fixed to the horizontal rod 46.
The driving lever 13 is fixed to the horizontal rod 50 which is pushed by the side protrusion of 28 and engages with the rear end of the lever 126.
0 and a return spring 132 for returning the lever 126 to its original position, and sliding contact between the drive lever 130 and the disk cam 128 is achieved by a slide pin 134 provided on the drive lever 130. This attachment/detachment cam mechanism 124 is controlled by the rotation of the feed claw mechanism 44 when the code number is shifted. That is, the disk cam 128 rotates due to the rotation of the feed claw mechanism 44, and the driving lever 1 is rotated via the slide pin 134.
30 to the left to engage lever 126. Rotation of the transverse rod 50 relative to the shaft 18 then causes the drive lever 130 to rotate the release cam 122 via the lever 126. When the release cam 122 rotates, the pawl 116 and the check pawl 120 are lifted by the cam portions on both sides, so that the stopper 11
8 and pawl 116 and pawl gear 62 and check pawl 1
20 is released. Then, the driving force of the torsion spring 78 is transmitted to the drive shaft 76 via the driven gear 110, rotating the ratchet gear 112 and the ratchet wheel 30 integrated with the drive shaft 76, causing the check digit type wheel 12 to rotate. give. On the other hand, since the ratchet gear 112 is always engaged with the locking pawl of the preset cam group 104, the rotation of the drive shaft 76 is caused by the rotation of the preset cam group 104.
It is carried out in conjunction with 4. At the same time, the preset cam group 104 receives the rotational force of the drive gear 102 in the same direction via the driven gear 110, and this rotational force is
The preset cam group 104 is used to assist the rotation of the preset cam group 104, and when a singular point occurs, the preset cam group 104 engages with the selected lever 106, just before the pole arm 48 fully rotates in the direction indicated by the dotted line.
The engagement between the lever 126 and the driving lever 130 is disengaged by a disengagement cam (fixed to the frame 14) of the driving lever 130 (not shown), and the check pawl 120 is engaged, and in the next step, the rear end of the lever 106 is attached to the frame 14. By tightening a fixed cam (not shown) to separate from the preset cam group 104, the driving gear 102 is able to engage the driven gear 11.
0 is rotated until the pawl 116 collides with the stopper 118, and is initialized. still,
A cam (not shown) fixed to the frame 14 that provides the rear end kicking action of the lever 106 is connected to the lever 106 and the preset cam group 1 in the next printing step.
04, so it does not necessarily need to be provided. As described above, when the check digit type wheel 12 is in steady state, the numbering type wheel 22A of the lowest digit is used.
The check digit type wheel 12 is fed intermittently in synchronization with
The drive control mechanism for idling is the same as that disclosed in Japanese Patent Application No. 131003/1983 by the same applicant. When the rotary press is operated with three numbering devices 34 attached to the rotating shaft 32 as shown in FIG. ~The numbering device 34 of No. 3 is printed once, and along with the code number, the modulus is 10, the weight is 1, 3, and 7.
A check digit is issued according to the following. Of course,
When printing is completed by contact with the impression cylinder 40, the roller 5
6 circumferentially surrounds the cam 36 and includes a numbering type wheel 22A of the lowest digit and a check digit type type wheel 12.
Send one pitch. For example, when the code number is shifted from 1st to 10th in Table 2, the above-mentioned drive control mechanism causes the check digit type to change by 1 pitch in the code number. The car 12 is rotated at idle so that it skips four times. Furthermore, as is clear from the embodiment shown in FIG.
The check digit type wheel 12 and the printing unit 10 are pressed against the impression cylinder because they are mounted on a fixed shaft 16 independent from the printing cylinder and are interlocked with the drive gear 28 of the ratchet wheel group 20 of the shaft 18 through the driven gear 24. The printing pressure generated during printing is not directly applied to the feed pawl mechanism and the drive control mechanism, making it possible to sufficiently withstand high-speed printing operations in rotary presses. The above embodiment of the numbering device for emitting check digits with a modulus of 10 has weights of 1, 3, and 7, and is based on the case where three devices are installed on the rotating shaft, but other suitable weights can also be used. Any combination can be made, and the number of units attached to the rotating shaft can be determined as appropriate. At this time, it should be noted that a skip wheel corresponding to the number of units installed should be used as the ratchet wheel 44A that drives the numbering type wheel 22A of the lowest digit of the code number.
The two points are that the cyclic numeral arrangement in Table 1 determined by the weight of the least significant digit is taken out and rearranged in increments corresponding to the number of units installed, and the cyclic numeral arrangement is used for the check digit type wheel 12. Next, an embodiment of a numbering device for a rotary press for printing a check digit using the modulus 11 along with a code number will be described. In the case of the modulus 11, the numbering device is almost the same as in the case of the modulus 10 shown in FIGS. They are different in that they are familiar. The cyclic number arrangement provided on the check digit type wheel 12 is determined by the lowest digit of the weight, and is as shown in Table 4 below.

[Table] For example, if weights 1, 3, and 7 are used, the cyclic number arrangement of the check digit type wheel 12 will be the arrangement symbol "0," 4, 8, 1,
5, 9, 2, 6, x, 3, 7". Also, if the number of numbering devices installed is three, the cyclic number array "0, 1, 2, 3, 4, 5,
6, 7, 8, 9, x'', that is, the array symbols in Table 4 above will be used. However, the problem with Modulus 11 is. This means that there are many code numbers where the check digit marked with an "x" in Table 4 is two digits, such as "10", and the code numbers with the check digit "x" are removed after printing. This requires a lot of effort. Therefore, in the numbering device of the present invention, when the check digit "10" is output due to a change in the code number, the code number is changed again, and the numbering device is structured so that the check digit "10" is not printed by skipping over the code number. This is to realize the following. If the check digit is replaced with "0" or "1" in the event of an overflow, the above-mentioned handling can of course be carried out, so the explanation will be omitted. FIG. 5 shows an embodiment of the numbering device of the present invention which prints out a check digit using a modulus 11. Parts common to those in FIG. The difference from Fig. 1 is that the ratchet wheel 3
The number of teeth of the 0.0, pawl gear 62 is 11, and around the check digit type wheel 12, 11 numbers in a cyclic number arrangement determined by the lowest weight in Table 4 are arranged at equal intervals. The following explanation will be made using weights 1, 3, and 7 as an example, and in order to simplify the explanation, it is assumed that two numbering devices 34 are attached to the rotating shaft as shown in FIG. 8. . For this reason, the check digit type wheel 12 has a circular numeric array "0, 8, 5, 2, x, 7,
4, 1, 9, 6, 3 (matching array signal E)" are provided. Further, a known skip wheel having two deep grooves is used as the lowest digit ratchet wheel 26A of the ratchet wheel group 20, and the lowest numbering device in one of the numbering devices driven by this skip wheel is used. The lower digit numbering type wheel 22A shows "0, 2, 4, 6, 8,
A code number arrangement of "0, 2, 4, 6, 8" is provided, and the numbering type wheel 22A of the lowest digit of the other numbering device has a code number arrangement of "1, 3, 5, 7, 9,
1, 3, 5, 7, 9" code number arrangement is provided. FIG. 6 shows the ratchet wheel 30 and check digit type wheel 1 in the embodiment of FIG.
In this figure, a protrusion 131 is formed on a pawl gear 62 that is provided integrally with the ratchet wheel 30. This projection 131 rotates the non-return pawl 120 as shown in the figure at the printing position where the check digit of the check digit type wheel 12 overflows, that is, becomes "10", and the movement of the non-return pawl 120 prevents the overflow of the check digit. It is used to detect. Referring again to FIG. 5, the check pawl 120 is fixed to the drive shaft 132, and the overflow of the check digit causes the drive shaft 132 to rotate. A flange casing 134 is fixed to the right end of the shaft 18, and a sliding flange 136 is mounted on the outside of the flange casing 134 to a spline shaft portion 138 at the end of the shaft 18 so as to be able to move laterally. This sliding flange 136 is biased toward the casing 134 by a coil spring 142 whose one end is fixed to a stopper pin 140 implanted in the spline shaft portion 138 . Sliding flange 136
A drive arm 54 is implanted on the circumferential surface of the drive arm 54, and a roller 56 is supported at the tip thereof. The drive shaft 132 to which the check claw 120 is fixed is extended to the position of the sliding flange 136, and a drive arm control plate 144 is fixed to the drive shaft 132 at a position where the flange casing 134 and the sliding flange 136 meet. . The drive mechanism of the drive arm 54 with this roller 56 is shown in detail in FIG. In FIG. 7A, the flange casing 134
A funnel-shaped receiving portion 146 is formed on the right side of the receiving portion 146, and a conical portion 148 projecting from the sliding flange 136 of this receiving portion 146 is fitted, so that no overflow of check data occurs. In this case, the drive arm control plate 144 is in the state shown, and the cam 36-1 shown in FIG. 8 is disposed on the rotation locus of the roller 56 at this time. Therefore, in a steady state in which no overflow occurs, the roller 56 of the numbering device contacts only the cam 36-1, and feeds the code number and check digit once per revolution. Next, when an overflow of the check digit occurs, the drive shaft 132 is rotated by the check pawl 120, so that the drive arm control plate 144 is rotated as shown in FIG. 7B.
is rotated and inserted between the flange casing 134 and the sliding flange 136, and the sliding flange 136 resists the coil spring 142 due to the contact between the tip of the drive arm control plate 144 and the conical portion 148 of the sliding flange 136. The roller 56 is then slid to the right, changing the rotation locus position of the roller 56. As shown in FIG. 8, another cam 36-2 is arranged on the rotation locus of the roller 56 in the state shown in FIG. 7B. Therefore, the roller 56 comes into sliding contact with the cam 36-2, causing the drive arm 54 to swing. That is,
If the roller 56 of the numbering device slides into contact with the first cam 36-1 in FIG. 8 to feed the code number and check digit, and an overflow of the check digit occurs at this time, as shown in FIG. 7B. The position of the roller 56 is changed, and then the code number and check digit are fed by sliding contact between the roller 56 and the next cam 36-2, and the check digit and code number that have overflowed are skipped. The drive arm 54 of the numbering device is actuated twice per revolution to move the numbering device over the numbering device. Next, let's look at the relationship between the code number and check digit (C/D) when the number of installed units is 2 and the weight is 1, 3, and 7. Become.

[Table] In Table 5, the numbers in circles indicate the singularity of the code number, that is, the number of check digit skips that occur due to digit shifting. In addition, in the specific example of Table 5, when the code number changes to "8" or "16" in the No. 1 numbering device, the check digit overflows, so the number shown in FIG.
The position of the roller 56 is changed as shown in FIG. 2, and the drive arm 54 is swung again to change to the next code number, and the code number with check digit enclosed by the dotted line is not printed. In this way, code numbers that would cause overflow are not printed, so the order of code numbers printed by the rotary press is 0, 1, 2, 3, 4, 5, 6, 7, 10, 9,
12, 11, 14, 13, 18, 15, 20, 17,...'', but the order of the code numbers is due to the fact that actual slip processing operations involve a mixture of code numbers. ,No problem. In addition, if the number of numbering devices installed on the rotary shaft of a rotary press is increased, check digit overflow will occur continuously in a specific numbering device, and two or more cams for actuating the drive arm must be provided. Not practical. As a result of consideration, it has been found that this situation occurs frequently when the number of numbering devices installed is eight or more. Therefore, in the embodiment of this invention, as shown in FIG.
It is desirable to select a sufficient number of cams to be installed by simply providing two cams 36-1 and 36-2. As described above, in the embodiment of the present invention in which a check digit based on modulus 11 is printed together with a code number, the code number where the check digit overflows is not printed, but is printed by skipping over to the next code number. This eliminates the need to remove code number sheets with unusable check digits from code number sheets that have been cut after printing. This greatly improves the yield of printing work, and improves printing efficiency with Modulus 11, which has a high error detection rate. This enabled the widespread use of code numbers with check digits. As explained above, the numbering device for a rotary press of the present invention is equipped with a mechanism that can withstand high pressure generated by high-speed printing of a rotary press in the printing unit part, so that it can be mounted on a rotary press, By using a check digit type wheel with a circular number arrangement according to the number of units installed, the numbering devices can be arranged radially around the same rotating shaft, increasing the printing speed. This enables printing in which code numbers that result in overflowed check digits that cannot be used as check digits are automatically removed.
