Description

  The present invention relates to a numbering device including a ring-feeding mechanism capable of feeding a plurality of ring-wheels with a single feeding claw.

  Conventionally, for example, it has been widely practiced to stamp and manage consecutive numbers on various documents, slips, etc., and as a printer for this purpose, numbers are automatically incremented each time they are stamped. Numbering devices are widely used.

  As a conventional numbering device, for example, as shown in Patent Document 1 and Patent Document 2, a feeding claw is usually attached to each ring. That is, the conventional ring-wheel feeding mechanism has a ring-ring rotating gear integrally provided on the side surface of each ring-shaped ring, and a feed claw that engages with the ring-ring rotating gear. When the numbered ring is rotated once, the tens feeding claw is operated in conjunction with this, and the numbered ring is rotated by one and the structure is moved up. The same applies to the hundreds and thousands.

  As described above, in the conventional numbering device, the wheel rotation gear is integrally provided on the side surface of each wheel, and a feed claw that engages with the wheel rotation gear is required for each wheel. As a result, the same number of feeding claws as the number of ring rings is required and the structure becomes complicated, and there is a gap for attaching the feeding claws between adjacent ring rings, which increases the width of the numbering device. There was a problem that.

JP 54-131425 A Japanese Utility Model Publication No. 26-5805

  The present invention solves the problems as described above, and can feed a plurality of ring wheels with one feeding claw, and secures a gap for attaching the feeding claw between adjacent ring rings. It is an object of the present invention to provide a numbering device that can be reduced in size in the width direction as much as possible.

  The numbering device of the present invention, which has been made to solve the above-described problems, includes a plurality of ring wheels in a case, a ring ring rotating gear that rotates the ring ring, and a ring ring rotating gear that rotates intermittently. A numbering device that houses the feeding claw and rotates the said ring ring intermittently by the operation of the feeding claw that is linked to the up and down movement of the slider mounted inside the case. A gear hole is provided at the bottom of one tooth groove of the gear, and the gear wheel rotating gear is overlapped on the same circumference so that the upper end of the tooth of the gear wheel rotating gear is exposed in this window hole. The teeth of the tens digit ring rotating gear exposed in the window hole are rotated together with the first digit ring rotating gear by one feeding claw provided corresponding to the gear ring rotating gear. It is characterized by this.

  A wheel for rotating the ring is formed on the side surface of the first digit ring, and an extension shaft portion projects from the tenth digit ring in the direction of the first digit ring. A gear wheel rotation gear is formed at the end of the extension shaft portion, and the first ring wheel rotation gear teeth and the tenth ring wheel rotation gear teeth overlap with each other on the same circumference. This is preferable, and this is the invention according to claim 2.

  The ring is composed of a disk-shaped rotor and a print belt attached to the outer periphery of the rotor, and a recess made of a reverse tapered wall is formed on the outer periphery of the rotor. It is preferable that a convex portion provided on the back surface of the print belt is engaged therein, and this is the invention according to claim 3.

  In addition, the rotary shaft of the ring is always in close contact with the printing surface of the ring and is rotated in conjunction with the up and down movement of the slider so that it jumps out to the outside when it is stamped. It is preferable that a movable stamp base is attached, and this is the invention according to claim 4.

  Moreover, it is preferable that the side surface of the case is provided with a lock claw for holding the position where the slider is raised, and this is the invention according to claim 5.

  In the invention according to claim 1, a window hole is provided at the bottom of one tooth groove of the first digit ring rotating gear, and the upper end of the tooth of the ten digit ring rotating gear is exposed in this window hole. The wheel rotation gears are stacked on the same circumference, and the teeth of the tens position wheel rotation gear exposed in the window hole are made one by one feed claw provided corresponding to the position wheel rotation gear. Since it is made to rotate together with the center wheel rotation gear, it has been possible to make only one feed claw for each wheel rotation gear in the past, and to have a simple structure. In addition, since a space for providing a ring-rotating gear between each ring is not required, the size in the width direction can be reduced as much as possible.

  In the invention according to claim 2, a ring-rotating gear is formed on the side surface of the first digit ring, and the extension shaft part is directed to the tenth digit ring in the direction of the first digit ring. A ring-shaped rotating gear is formed at the end of the extension shaft, and the teeth of the first-ranked wheel rotating gear and the tenth-shaped wheel-rotating gear have the same circumference.

The numbering device of the present invention accommodates a plurality of ring wheels, a ring ring rotating gear for rotating the ring ring, and a feed claw for intermittently rotating the ring rotating gear in the case. The basic operation is to intermittently rotate the ring wheel by the operation of the feed claw that is interlocked with the moving up and down of the mounted slider.

Hereinafter, the present invention will be described with reference to the drawings.
In the figure, 1 is a case composed of two split members. Reference numeral 2 denotes a triple ring consisting of a first digit ring 2a, a tenth digit ring 2b, and a hundred digit ring 2c, and is attached in the case 1. Reference numeral 3 denotes a rotating shaft of the ring 2, and reference numerals 3 a and 3 b denote crowns. The rotating ring 3 is pivotally supported by the case 1 so that the ring 2 can be rotated. Reference numeral 4 denotes a frame-like slider that is mounted inside the case. A spring 5 is mounted on the upper portion, and is normally biased downward. Further, a seal opening 4 a is provided on the bottom surface of the slider 4, and a guide long hole 4 b for guiding the rotary shaft 3 is provided on the side surface.

FIG. 6 is a perspective view showing a main part of the present invention, in which 6 is a feed claw. The feed claw 6 is attached to the top plate 4c of the slider 4, and the locking portion 6b at the tip is always urged toward the ring wheel side by the elastic force of the torsion coil spring 6a. It should be noted that the feeding pawl 6 is not limited to the coil spring 6a, but may have any configuration as long as the object can be achieved, such as using the elasticity of the resin itself or using another spring material. Can do.
The feed claw 6 moves up and down in conjunction with the up and down movement of the slider 4 at the time of stamping, and intermittently rotates the ring wheel 2. This will be described later.

FIGS. 7 to 9 show the rotors in the 1st, 10th, and 100th positions. 7a is a first-order rotor, and a first-order wheel rotation gear 8a is formed on this side surface. Reference numeral 7b denotes a tenth-order rotor, and an extension shaft portion 7d projects from the side surface in the direction of the first digit ring 2a, and an end portion of the extension shaft portion 7d is provided on the side surface. A tens digit wheel rotating gear 8b is formed. Furthermore, 7c is a hundreds-order rotor.
In addition, shaft holes 9a, 9b, and 9c for inserting the rotating shaft 3 are formed at the center of each rotor. In the illustrated example, the first-order rotor 7a and the tenth-order rotor 7b have a structure that freely rotates around the shaft without engaging with the rotating shaft 3. On the other hand, the hundreds of rotors 7c have a locking relationship with the rotating shaft 3 and do not idle around the shaft. When the crown 3b is turned by hand, the hundreds of rotors 7c rotate together with the rotating shaft 3. It has a moving structure.

As shown in FIG. 6, a window hole 10 is provided at the bottom of one tooth groove of the first digit ring rotating gear 8a, and the upper end of the tooth of the ten digit ring rotating gear 8b is formed in the window hole 10. Is configured to be exposed. That is, when the two ring wheel rotating gears 8a and 8b are combined, the tenth ring wheel rotating gear 8b is shifted toward the first ring wheel 2a by the length of the extension shaft portion 7d. The teeth of the digit ring rotating gear 8a and the teeth of the ten digit ring rotating gear 8b overlap each other on the same circumference. As a result, the upper end of the tooth of the tens digit ring rotating gear 8b is exposed from the window hole 10, and when the engaging portion 6b of the feed claw 6 comes into contact with the first digit ring rotating gear 8a. The tens digit wheel rotating gear 8b also rotates.
In other words, only when the first digit ring rotating gear 8a makes one rotation and the upper end of the tooth of the ten digit ring rotating gear 8b is exposed from the window hole 10, the tenth digit ring rotating gear by the feed claw 6 is exposed. Only one tooth of 8b is sent and carried, and thereafter, by repeating the same rotation operation, the number of the ring is automatically raised from 1 to 99.

In the illustrated example, the crown 3b is manually rotated to rotate the rotary shaft 3, thereby turning the hundreds-shaped ring 2c to carry the carry. Similarly to the wheel rotating gear 8b, a structure in which the feeding claw 6 can be automatically lifted can be used. In this case, an extension shaft portion (not shown) similar to that of the tens position rotor is projected from the hundred position rotor 7c, and a hundredth ring-shaped rotation is provided at the end of the extension shaft portion. A diverting gear (not shown) is formed, and the hundreds-shaped wheel rotation gear is configured to overlap the same circumference as the teeth of the tens-digit wheel rotation gear 8b. On the other hand, a window hole (not shown) is provided at the bottom of one tooth groove of the tens digit wheel rotating gear 8b so that the teeth of the hundred digit ring rotating gear are exposed from the window hole. When the engaging portion 6b of the feeding claw 6 comes into contact, the hundreds of ring-shaped ring rotating gears rotate together with the tenth-shaped ring-shaped rotating gears 8b. The gears for rotating the hundreds of ring wheels can be automatically carried one by one for each rotation of.
In this case, a structure can be adopted in which the number of the ring is automatically raised from 1 to 999. Further, with the same structure, even if the numbering device has four digits or more, only one feeding claw 6 can be used to rotate the ring-rotating gears of all the digits so as to be continuously raised.

As described above, the feed claw 6 is conventionally provided for each wheel for rotating the wheel, but in the present invention, only one can be provided, and a simple structure can be obtained. Since no space for providing the wheel rotating gear is required, the size in the width direction can be reduced as much as possible, and a compact numbering device can be provided.
In the above description, the character ring and the gear wheel rotation gear are integrally formed. However, the character wheel rotation gear only needs to rotate the character ring. In addition to the ring, it may be provided on the upper part of the ring, and the ring may be rotated by being engaged with the surface of the print belt or a gear provided on the ring.

As shown in FIG. 10, for example, when the first ring wheel 2 a is taken as an example, the ring wheel 2 includes a disk-shaped rotor 7 a and a print belt 11 attached to the outer periphery of the rotor 7 a. Thus, a concave portion 12 made of a reverse tapered wall surface is formed on the outer periphery of the rotor 7a, and a convex portion 13 provided on the back surface of the print belt 11 is engaged with the concave portion 12.
Thereby, the printing belt 11 can be accurately and firmly attached to the outer periphery of the rotor 7a, and printing with high accuracy can be performed. The tens place ring 2b and the hundreds form ring 2c have the same structure.

The rotary shaft 3 of the ring 2 is normally in close contact with the printing surface of the ring 2 (see FIG. 1) and is jumped to the outside during the stamping (see FIG. 11). A movable stamp base 14 that is rotated in conjunction with the up and down movement of the slider 4 is attached. 1 and 11, the above-described operation is achieved by using a general parallel link structure in which the front and back of the stamp table 14 are connected by two parallel links 15a and 15b. Of course, any link structure can be adopted as long as it achieves the above.
As a result, it is possible to automatically supply ink to the printing surface and achieve clear printing, and since the stamp base 14 is a flip-up type, there is no obstruction and a compact structure. can do.

The side surface 1a of the case 1 is provided with a lock claw 16 for holding the position where the slider 4 is raised to the maximum, while the side surface of the corresponding slider 4 is provided with a projecting piece 17, When 4 rises and the protruding piece 17 gets over the lock claw 16, the downward movement of the slider 4 is stopped and the raised position is maintained. Further, an unlocking projection 16a is provided above the lock claw 16, and by pushing the projection 16a inward, the lock claw 16 and the projection piece 17 are unlocked to move the slider 4 downward. It has a structure that can be lowered.
Thereby, when not in use, the slider 4 can be held in the raised position to form a compact form, and excellent handling properties can be exhibited.

In the numbering device of the present invention configured as described above, after the case 1 is pushed down and imprinted, the case 1 is automatically raised by the elastic force of the spring 5 to wait for the next imprinting. As the case 1 moves up, the feeding claw 6 rotates one tooth of the first-order wheel rotation gear 8a to carry the first digit up by one digit.
In this way, when the first digit ring is automatically fed from 1 to 9 and again comes to 0, the upper tooth end of the tenth digit ring rotation gear 8b is exposed in the window hole 10 provided at the bottom of the tooth gap. It will be in the state. In this case, when the engaging portion 6b of the feed claw 6 comes into contact with the tooth groove, the tens digit ring rotating gear 8b is rotated together with the first digit ring rotating gear 8a. The number will be incremented by one.
Thereafter, the carry is similarly cut back, and the number of the ring is automatically carried up from 1 to 99. In addition, if the upper end of each ring-shaped wheel gear is exposed in the window hole 10 with the same structure, the number of hundreds or more will be automatically numbered with only one feed claw and even with a three-digit or more numbering device. Can be carried forward.
In this way, each time a stamp is made, the number of the ring is moved up and used as a numbering device. However, it is not necessary to provide a feed claw for each wheel for rotating the ring as in the prior art, and only one can be provided. Can be a simple structure. In addition, since a space for providing a ring-ring rotating gear between the ring-shaped rings is not required, the size in the width direction can be reduced as much as possible.
