Description
- The present invention relates to an electric numbering device that prints a number on a sheet that is a printing target.
- As a numbering device of this type, there is a numbering device disclosed in, for example, Japanese Patent No.
5457175 - Each driving mechanism includes a motor formed long in the axial direction of the number wheels and supported by a frame in a cantilevered state, a driving shaft supported on the frame in a cantilevered state so as to be in parallel to the motor and connected to the rotating shaft of the motor by gear coupling, a driving gear fixed to the driving shaft and meshed with a driven gear of a corresponding number wheel. The plurality of driving mechanisms are arranged at a plurality of positions spaced apart from each other at a predetermined interval in the circumferential direction of the number wheels when viewed from the axial direction of the number wheels. The motors of the driving mechanisms provided on one frame are arranged at positions where they are adjacent to the plurality of motors on the other frame in the circumferential direction of the number wheels when the two frames are combined with each other.
- In such an arrangement, however, the motors that are heat generating components are stored in a narrow space. For this reason, the temperature of each motor readily rises, and the motor may cause an operation error. Hence, in the numbering device disclosed in literature 1, the reliability of a printed number lowers.
- Additionally, in the above-described arrangement, maintenance is impossible unless the pair of frames are disassembled. Hence, in this numbering device, the operability in the maintenance of the motors is low.

first frame 2a and thesecond frame 2b are arranged at a predetermined interval in the axial direction of the first to10th number wheels 3 to 12 and partition (the space of a part of) the periphery of all the drivengears 3a to 12a into a gear storage space SP1 and an external space SP2. The gear storage space SP1 is a space to store the drivengears 3a to 12a, which corresponds to "first space" in the present invention. The external space SP2 is a space outside the gear storage space SP1, which corresponds to "second space" in the present invention. - As shown in
Fig. 1 , the first to thirdmulti-shaft driving mechanisms 13 to 15 are arranged on the opposite side (the lower side inFig. 1 ) of theprinting position 50 of the first to10th number wheels 3 to 12 in the radial direction while being arranged in the circumferential direction of the first to10th number wheels 3 to 12.

multi-shaft driving mechanisms 13 to 15 employ the same arrangement, as shown inFig. 2 . Each of the first to thirdmulti-shaft driving mechanisms 13 to 15 is formed by adirect driving system 22 using afirst motor 21 as a power source, and anindirect driving system 24 using asecond motor 23 as a power source. Thedirect driving system 22 is formed by thefirst motor 21, afirst driving shaft 25 connected to thefirst motor 21, and afirst driving gear 26 fixed to thefirst driving shaft 25. - The

Thefirst motor 21 is located in the external space SP2. Thefirst motor 21 is connected to the one end of thefirst driving shaft 25 and drives thefirst driving shaft 25. Thefirst driving gear 26 meshes with a predetermined first driven gear of the plurality of drivengears 3a to 12a described above. - In this embodiment, the

In this embodiment, the drivengear 6a of thefourth number wheel 6, the drivengear 5a of thethird number wheel 5, and the drivengear 4a of thesecond number wheel 4 correspond to "first driven gear" in the present invention. - The
indirect driving system 24 is formed by asecond driving shaft 27 located on the same axis as the above-described first drivingshaft 25, asecond driving gear 28 fixed to thesecond driving shaft 27, anintermediate shaft 29 arranged on the outer side of thesecond driving shaft 27 in the radial direction of the number wheels, and thesecond motor 23 connected to one end of theintermediate shaft 29. - The
second driving shaft 27 includes one end rotatably supported by thethird frame 2c, and the other end rotatably supported by thesecond frame 2b. The one end of thesecond driving shaft 27 is located to be adjacent to the other end of thefirst driving shaft 25. The other end of thesecond driving shaft 27 projects from thesecond frame 2b to the side of the external space SP2. A driven-side pinion 31 is attached to the projecting portion. Thesecond driving gear 28 meshes with a predetermined second driven gear of the plurality of drivengears 3a to 12a described above, which is different from the above-described first driven gear. - In this embodiment, the

In this embodiment, the drivengear 12a of the10th number wheel 12, the drivengear 11a of theninth number wheel 11, and the drivengear 10a of theeighth number wheel 10 correspond to "second driven gear" in the present invention. - The
intermediate shaft 29 is arranged on the outer side of thesecond driving shaft 27 in the radial direction of the number wheels, and extends in parallel to thesecond driving shaft 27. One end of theintermediate shaft 29 is rotatably supported by thefirst frame 2a, and the other end of theintermediate shaft 29 is rotatably supported by thesecond frame 2b. The other end of theintermediate shaft 29 extends through thesecond frame 2b and projects to the side of the external space SP2. A driving-side pinion 32 is attached to the projecting portion. The driving-side pinion 32 meshes with the above-described driven-side pinion 31. The other end of theintermediate shaft 29 is thus connected to thesecond driving shaft 27 by gear coupling. - The
second motor 23 is fixed to thefirst frame 2a in a state in which the axis of thesecond motor 23 is parallel to an axis of the first to10th number wheels 3 to 12. Thesecond motor 23 is located in the external space SP2. Thesecond motor 23 is connected to the one end of theintermediate shaft 29 and drives theintermediate shaft 29. - As shown in
Fig. 2 , the first to fourth single-shaft driving mechanisms 16 to 19 employ the same arrangement. Each of the first to fourth single-shaft driving mechanisms 16 to 19 is formed by athird motor 33, athird driving shaft 34 connected to thethird motor 33, and athird driving gear 35 fixed to thethird driving shaft 34. - The
third driving shaft 34 includes one end rotatably supported by thefirst frame 2a, and the other end rotatably supported by thesecond frame 2b. Thethird motor 33 is fixed to thefirst frame 2a in a state in which the axis of thethird motor 33 is parallel to the axis of the first to10th number wheels 3 to 12. Thethird motor 33 is located in the external space SP2. Thethird motor 33 is connected to the one end of thethird driving shaft 34 and drives thethird driving shaft 34. Thethird driving gear 35 meshes with a predetermined third driven gear of the plurality of drivengears 3a to 12a described above, which is different from the above-described first and second driven gears. - In this embodiment, the
third driving gear 35 included in the first single-shaft driving mechanism 16 meshes with the drivengear 8a of thesixth number wheel 8, and thethird driving gear 35 included in the second single-shaft driving mechanism 17 meshes with the drivengear 7a of thefifth number wheel 7. In addition, thethird driving gear 35 included in the third single-shaft driving mechanism 18 meshes with the drivengear 3a of thefirst number wheel 3, and thethird driving gear 35 included in the fourth single-shaft driving mechanism 19 meshes with the drivengear 9a of theseventh number wheel 9. In this embodiment, the drivengear 3a of thefirst number wheel 3, the drivengear 7a of thefifth number wheel 7, the drivengear 8a of thesixth number wheel 8, and the drivengear 9a of theseventh number wheel 9 correspond to "third driven gear" in the present invention. - In the thus configured numbering device 1, the
second motors 23 of the first to thirdmulti-shaft driving mechanisms 13 to 15 are arranged on the outer side of thefirst motors 21 in the radial direction of the first to10th number wheels 3 to 12. In other words, the motors are arranged at two points in the radial direction of the number wheels. When an arrangement in which the plurality offirst motors 21 and the plurality ofsecond motors 23 are arranged in the circumferential direction of the first to10th number wheels 3 to 12 is employed, the plurality of motors can be arranged in lines in the inner and outer sides in the radial direction. Since it is therefore possible to provide many motors without interference between these motors, the number of digits of a number to be printed can be increased. - Additionally, all the motors are arranged outside the gear storage space SP1 (in the external space SP2), and the
first motors 21 are spaced apart from thesecond motors 23 in the radial direction of the first to10th number wheels 3 to 12. For this reason, the heat of the first andsecond motors - Hence, according to this embodiment, it is possible to provide the numbering device 1 capable of suppressing an increase in the motor temperature and raising reliability and also easily performing maintenance while employing an arrangement capable of increasing the number of digits of a number to be printed.
- In the numbering device 1 according to this embodiment, the first to
third motors 10th number wheels 3 to 12. In addition, the first to thirdmulti-shaft driving mechanisms 13 to 15 are arranged on the opposite side of theprinting position 50 of the first to10th number wheels 3 to 12 in the radial direction while being arranged in the circumferential direction of the first to10th number wheels 3 to 12. Furthermore, the first to fourth single-shaft driving mechanisms 16 to 19 are arranged on the side of theprinting position 50 with respect to the first to thirdmulti-shaft driving mechanisms 13 to 15 while being arranged in the circumferential direction of the first to10th number wheels 3 to 12. Hence, since the first to thirdmulti-shaft driving mechanisms 13 to 15 which increase the size in the radial direction of the first to10th number wheels 3 to 12 are arranged on the axis side of the number cylinder with respect to the first to10th number wheels 3 to 12, it is possible to provide the numbering device 1 that is compact in the conveyance direction of a sheet to print a number. The numbering device 1 having this arrangement is suitable in a case in which the longitudinal direction of a rectangular sheet is parallel to the axial direction of the number cylinder, that is, in a case in which a character string in the horizontal direction is printed at an end of the sheet in the widthwise direction. - In this embodiment, the second driven gears are driven gears driven by the second driving gears 28 of the first to third
multi-shaft driving mechanisms 13 to 15. In other words, the second driven gears are driven gears to which power is transmitted via a power transmission path including the gear coupling portion formed from the driven-side pinion 31 and the driving-side pinion 32. The second driven gears are the drivengears 10a to 12a of the eighth to10th number wheels 10 to 12 that print numbers in digit places relatively higher than those of the first driven gears in a number having a plurality of digits printed by the plurality ofnumber wheels 3 to 12. For this reason, a number wheel in a higher digit place rotates less frequently as compared to a number wheel in a lower digit place, and the use frequency of the gear coupling portion is relatively low. In the multi-shaft type, the number of gear coupling portions is larger than in the single-shaft type. However, according to this embodiment, the reliability is high. - A numbering device according to the second embodiment of the present invention will be described next with reference to
Figs. 3 and4 . The same reference numerals as inFigs. 1 and2 denote the same or similar members inFigs. 3 and4 , and a detailed description thereof will appropriately be omitted. - In a
numbering device 41 shown inFig. 3 , first to thirdmulti-shaft driving mechanisms 13 to 15 are arranged on one side (the left side inFig. 3 ) of first to10th number wheels 3 to 12 in the circumferential direction with respect to aprinting position 50 of the first to10th number wheels 3 to 12 while being arranged in the circumferential direction of the first to10th number wheels 3 to 12. In addition, first to fourth single-shaft driving mechanisms 16 to 19 are arranged on the other side (the right side inFig. 3 ) of the first to10th number wheels 3 to 12 in the circumferential direction with respect to theprinting position 50 of the first to10th number wheels 3 to 12 while being arranged in the circumferential direction of the first to10th number wheels 3 to 12. - As shown in
Fig. 4 , aframe 2 according to this embodiment is formed by first andsecond frames 10th number wheels 3 to 12 when viewed from a direction facing theprinting position 50 of the first to10th number wheels 3 to 12, athird frame 2c located between thefirst frame 2a and thesecond frame 2b, and fourth andfifth frames - The
fourth frame 2d forms the boundary between a gear storage space SP1 and an external space SP2 in cooperation with thefirst frame 2a on one side (the lower side inFig. 4 ) in the axial direction of the first to10th number wheels 3 to 12. Thefifth frame 2e forms the boundary between the gear storage space SP1 and the external space SP2 in cooperation with thesecond frame 2b on the other side (the upper side inFig. 4 ) in the axial direction of the first to10th number wheels 3 to 12. Thefifth frame 2e and thefirst frame 2a are arranged inside the two ends of anumber wheel assembly 42 formed from the first to10th number wheels 3 to 12 in the axial direction of the first to10th number wheels 3 to 12. - More specifically, the
first frame 2a is arranged at a position on the side of the10th number wheel 12 with respect to thefirst number wheel 3 in the axial direction of thenumber wheel assembly 42. For this reason, certain portions of first andsecond motors multi-shaft driving mechanisms 13 to 15 overlap one end of the above-describednumber wheel assembly 42 in the axial direction. Three first driving gears 26 of the first to thirdmulti-shaft driving mechanisms 13 to 15 according to this embodiment mesh with drivengears 7a to 9a of the fifth toseventh number wheels 7 to 9. - On the other hand, the
fifth frame 2e is arranged at a position on the side of thefirst number wheel 3 with respect to the10th number wheel 12 in the above-described axial direction. The first to fourth single-shaft driving mechanisms 16 to 19 according to this embodiment are supported by thefifth frame 2e and thefourth frame 2d. That is, each ofthird driving shafts 34 of the first to fourth single-shaft driving mechanisms 16 to 19 includes one end rotatably supported by thefourth frame 2d, and the other end rotatably supported by thefifth frame 2e. -
Third motors 33 of the first to fourth single-shaft driving mechanisms 16 to 19 extend from thefifth frame 2e to the opposite side of thefourth frame 2d in the external space SP2. For this reason, thethird motors 33 are arranged at positions to overlap the other end of the above-describednumber wheel assembly 42 in the axial direction. Eachthird motor 33 is connected to the other end of thethird driving shaft 34 and drives thethird driving shaft 34. Four third driving gears 35 of the first to fourth single-shaft driving mechanisms 16 to 19 are fixed to thethird driving shafts 34 and mesh with drivengears 3a to 6a of the first tofourth number wheels 3 to 6. - In the
numbering device 41 according to this embodiment as well,second motors 23 of the first to thirdmulti-shaft driving mechanisms 13 to 15 are arranged on the outer side offirst motors 21 in the radial direction of the first to10th number wheels 3 to 12. It is therefore possible to provide many motors without interference between the motors and increase the number of digits of a number to be printed, as in the first embodiment. - Additionally, all the motors are arranged outside the gear storage space SP1, and the
first motors 21 and thesecond motors 23 are spaced apart in the radial direction of the first to10th number wheels 3 to 12. For this reason, the heat of the motors is readily dissipated, and other motors never impede when doing maintenance. Hence, in this embodiment as well, it is possible to provide the numbering device capable of suppressing an increase in the motor temperature and raising reliability and also easily performing maintenance while employing an arrangement capable of increasing the number of digits of a number to be printed. - In the
numbering device 41 according to this embodiment as well, the second driven gears driven by the first to thirdmulti-shaft driving mechanisms 13 to 15 are drivengears 10a to 12a of the eighth to10th number wheels 10 to 12 that print numbers in digit places relatively higher than those of the first driven gears in a number having a plurality of digits printed by the plurality of number wheels. For this reason, the use frequency of the gear coupling portion is relatively low, and the reliability becomes high, as in the first embodiment. - In this embodiment, the first to third
multi-shaft driving mechanisms 13 to 15 are arranged on one side of theprinting position 50 of the first to10th number wheels 3 to 12 in the circumferential direction of the number wheels while being arranged in the circumferential direction. In addition, the first to fourth single-shaft driving mechanisms 16 to 19 are arranged on the other side of theprinting position 50 in the circumferential direction while being arranged in the circumferential direction. Hence, since the first to thirdmulti-shaft driving mechanisms 13 to 15 which increase the size in the radial direction of the first to10th number wheels 3 to 12 are arranged on one side of the first to10th number wheels 3 to 12 when viewed from a direction opposite to theprinting position 50, it is possible to provide thenumbering device 41 that is compact in the conveyance direction of a sheet to print a number. - The
first frame 2a and thefifth frame 2e according to this embodiment are located inside the two ends of thenumber wheel assembly 42 in the axial direction of the first to10th number wheels 3 to 12. For this reason, all the motors overlap thenumber wheel assembly 42 in the axial direction, and thenumbering device 41 that is compact in the axial direction can be provided. Thenumbering device 41 is appropriate in a case in which the longitudinal direction of a rectangular sheet is orthogonal to the axial direction of the number cylinder, that is, in a case in which a character string long in the vertical direction is printed at an end of a sheet in the longitudinal direction. - In the above embodiments, the
numbering devices 1 and 41 each including the first to thirdmulti-shaft driving mechanisms 13 to 15 and the first to fourth single-shaft driving mechanisms 16 to 19 have been described. However, the present invention is not limited to this. That is, it is possible to employ an arrangement that drives all number wheels by only the multi-shaft driving mechanisms. Additionally, in each embodiment, thefirst frame 2a and thesecond frame 2b may replace each other.
