Abstract

<P>PROBLEM TO BE SOLVED: To provide a zero reset type numbering device eliminating the defects of existing manual numbering devices wherein a long time is required because a thin bar or the like is used to rotate a wheel piece by piece and character by character in one direction (in a direction of 1→2→3→ to →7→8→9→0) to adjust a seal position to zero in order to reset zero in the following operation after terminating the numbering operation of accumulating figures one by one, and the operation is troublesome because the numbering device is turned upside down to confirm irregular wheel numbers and then figures of all digits have to be made zero. <P>SOLUTION: The numbering device adjusts all the wheel figures in the seal positions of the respective digits to zeroes which have been made irregular by the seal operation of the continuous numbers of figures by performing one rotation of a numbering wheel support shaft 5 provided on the other side part of a frame 2 and extended outward from a long opening 4. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

    The present invention relates to a numbering device.

  In the conventional manual type numbering device, in order to reset the numbers of all the girders to 0 and reset them, each girder was pushed and fed while rotating one by one with a stick. The resetting work was time consuming and could not be completed in a short time.

  That is, the one shown in FIG. 3 is a conventional zero-feed method, and the foil cannot be rotated counterclockwise because the trough of the gear is caught on the tip of the feed claw, and the numerical value is printed at the lowest print position. The wheel of each digit must be rotated clockwise with a rod until 0 is reached.

  As an improvement of the numbering device having such drawbacks, there are those described in the following public utility model gazettes, which have the following disadvantages.

Japanese Utility Model Publication No. 52-153428

  In this known device, a movable piece and a spring are attached to a notch that passes through the center of the shaft diameter, but the thickness of the shaft is large enough to house the movable piece and spring components. Since the thing of a diameter was required, the whole had to be enlarged comparatively.

  In addition, in this known device, high precision is required for machining the notch positions of the shafts facing a plurality of plate cylinders in order to compare and align the positions of the movable piece and the plate cylinder in the longitudinal direction of the shafts. Therefore, it became expensive.

  Further, the shaft of this known device requires notches for mounting a movable piece and a spring as many as a plurality of plate cylinders, and this also increases the cost.

  In addition, a groove for allowing the movable piece to enter is required in the inner diameter portion of the plate cylinder of this known device, and the printing pressure concentrates on the groove when printing the letter at the groove position, so the shape of the groove collapses. There was a risk of stopping the operation of the movable piece.

  Further, in this known device, there is no shaft positioning means when it is rotated once to make it clear to zero.

  Therefore, the problem to be solved by the present invention is that in the conventional numbering device, the numbering operation for accumulating numbers one by one is terminated, and the next operation returns zero (all digits are zero). Rotate the foil in one direction using a thin stick etc. one by one and one character at a time (1 → 2 → 3 → ・ ・ ・ ・ ・ → 7 → 8 → 9 → 0) The marking position was adjusted to 0. For example, when a three-digit foil is used, a long time is required because the foil needs to be rotated up to three times.

  Further, in order to perform the operation described in the above [0011], the numbering device is turned upside down, and after checking the wheel numbers that are not aligned, it is necessary to set the numbers of all the digits to 0. was there.

  Therefore, the present invention has an object to provide a zero return type numbering device that eliminates the disadvantages of the conventional manual numbering device, including the numbering device according to the known device. is there.

  In the present invention, by rotating the spindle of the numbering wheel extending outward from the long opening provided on the other side of the frame, the digit of each digit that has become uneven in the stamping operation of consecutive numbers It is a numbering device that aligns all the foil numbers at the stamping positions to zero.

  The device of the present invention does not need to be turned over at the time of return zero work as in the case of the conventional device, and the return zero operation can be performed easily and quickly. It eliminates all the costs and makes office equipment extremely convenient.

  Reference numeral 1 denotes a knob provided at the center of the frame 2 having a bowl shape. By pushing this knob, the numbering wheel unit, which will be described later, is moved down to be printed and rotated to feed characters.

  One side 3 of the frame 2 is in a closed state, while the other side 3 'is provided with a long opening 4 from the center to the lower end.

  Reference numeral 5 denotes a support shaft which engages with a guide rail provided on the inner surface of the frame 1 at the inner center of the frame 2, and the other end of the support shaft is on the other side of the frame. It protrudes outward from the long opening 4 of the part 3 ′.

  Hereinafter, the configuration and operation of the numbering device will be described in order.

  1. The marking operation of the numbering device will be described with reference to the drawings.

  FIG. 1 shows a stationary state where the hand is not touched, and FIG. 2 shows that a supporting shaft 5 is supported in the frame 2 between the guide rail on one side and the long opening 4 on the other side by pushing the knob 1 by hand. A case is shown in which numbers constituting the foil 6 included in the lowered numbering unit a are stamped, for example, numbers located on the lowermost surface of the foil on the paper surface.

  When the hand is released from the knob 1, an ammunition machine (not shown) installed near the knob 1 pushes up the unit to return to the state shown in FIG.

  2. The rotation mechanism of the numbering wheel will be described.

  FIG. 3 shows a rotary feed mechanism for a numbering wheel common to the conventional device and the present invention.

  On the outer surface portion of the foil 6, the entire circumference is divided into 10 equal parts and numerals 0 to 9 are provided. Similarly, the gear 7 divided into 10 equal parts on the entire circumference is integrated with the wheel 6 and fixed to the support shaft 5 so as to be freely rotatable.

  The feed claw 8 is fixed to the claw shaft 9 so as to be freely rotatable, and the feed claw tip 10 is always in contact with the gear-shaped outer peripheral portion of the gear 7 by splaying (not shown).

  The claw shaft 9 oscillates within the range of arrows 9a and 9b in the vertical marking operation shown in FIGS. When the knob 1 is raised, the claw shaft 9 is at the position 9a, and when the knob 1 is lowered (during the marking state), the claw shaft 9 is at the position 9b. (See Figure 3)

  With the above configuration, the foil 6 operates as follows in FIG.

  (1) When knob 1 is lowered (during operation of marking number 0 in FIG. 3)

  The claw shaft 9 rotates from 9a to 9b counterclockwise about the wheel spindle 5. The feed claw 8 moves around the claw shaft 9 as the feed claw tip 10 pushed by a ridge (not shown) moves while climbing the inclined surface portion 11 of the gear 7 against the pressure of the ridge. Turn counterclockwise to escape. At this time, the gear 7 and the wheel 6 are not rotated by a lock mechanism (not shown). When the claw shaft 9 moves to the position 9b, the feed claw tip 10 falls into the gear-shaped trough 12 of the gear 7 due to the ridge pressure.

  (2) When knob 1 is raised

  The claw shaft 9 rotates clockwise from 9b to 9a. The feed claw tip 10 rotates clockwise by one pitch (36 degrees) while pushing the trough 12 of the gear 7. The integrated gear 7 and foil 6 are also rotated clockwise by one pitch (36 degrees), and the lowest number printed is changed from 0 to 1. The pressing force of the ammunition (not shown) of [0022] is sufficient for pushing up the numbering unit a and for the feed claw 8 to rotate the wheel 8 and the gear 7. (See Figs. 3 and 4)

  (3) Repeated lowering and raising of knob 1

  The print position (bottom position) of the wheel 6 is incremented by 1 each time the knob 1 is repeatedly lowered and raised.

  3. The nulling method of the present invention will be described.

  The pin 13 is fixed to a part of the wheel 6 integral with the gear 7. A freely rotatable ratchet 14 and a winding strip 15 are attached around the pin 13.

  The rotation of the ratchet 14, which always tries to rotate counterclockwise around the pin 13, is stopped by the winding ridge 15, because the tip 14 ′ of the ratchet 14 hits the inclined surface 16 of the L-shaped cut portion 17 of the support shaft 5. is doing.

  FIG. 4 shows the basic state as a numbering device, with the lowest number of the foil 6 being 0.

  A part of the cross section of the support shaft 5 has the shape of the L-shaped cut portion 17, and the axial length is longer than the entire width of the plurality of foils 6.

  The reference position in the rotation direction of the support shaft 5 is the state in which the lowest digit (printing position) of the wheel 6 is 0, and the tip end portion 14 ′ of the ratchet 14 falls in the groove of the L-shaped cut 17 of the support shaft 5. The reference position is locked so as not to shift in the rotational direction by means described later.

  The foil 6 explained in the feeding of the numbering foil is rotated one by one in the clockwise direction by the swinging of the feeding claw 8, and the number 1 is added to the lowest character at the printing position.

  As the wheel 6 rotates, the ratchet 14 is also pulled by the pin 13 and rotates clockwise about the support shaft 5. At this time, the ratchet 14 rotates clockwise around the pin 13 while resisting the pressing force of the winding ridge 15 while the tip end portion 14 ′ rises to the inclined surface portion 16 of the support shaft 5 and moves to the outer peripheral high portion. .

  FIG. 5 shows a state in which the foil 6 is rotated by one character. (State figure in which the lowest digit 0 has moved to the number 1)

  When the ratchet 14 is rotated by one character, the tip portion 14 ′ is at the outer peripheral height position of the support shaft 5. Thereafter, as the foil 6 rotates clockwise by the numbering wheel rotation mechanism, the ratchet 14 rotates together with its tip end 14 ′ applied to the outer peripheral height of the support shaft 5.

  When the support shaft 5 is rotated once in the clockwise direction by the means described later, the ratchet 14 in various positions depending on the state of the stamped numbers is rotated while the face 18 of the L-shaped cut portion 17 is pressed while pushing the tip portion 14 ′. The wheel 6 is rotated in the same direction as the support shaft 5 (clockwise) via the 14 pins 13. In FIG. 4 where the rotation of the support shaft 5 in the clockwise direction is stopped, the lowest digit (printing position) of all the multiple-digit wheels 6 having the same return zero is zero. (The mechanism for securing the stop position of the support shaft 5 will be described later.)

  4). The rotation and locking of the support shaft will be described.

  In FIG. 4, the support shaft 5 can be rotated clockwise by a zero return operation of the wheel 6. In addition, in order to align the lowest number (printing position) of all the multiple-digit foils 6 to 0, the position of the groove of the L-shaped cut portion 17 is always kept at the same position when the return zero operation is completed. Locked.

  Therefore, the above two points will be described next.

  (1) Spindle rotation and locking

  FIG. 6 is an enlarged exploded detail view of part A of FIG. 1, and the configuration will be described below.

  The slide knob 19 is rotatable with respect to the support shaft 5 and can also slide in the axial direction.

  In the fixed knob 20, the numeral 0 of the wheel 6 in FIG. 4 is the lowest position (printing position), and the face 18 of the L-shaped cut portion 17 of the support shaft 5 is located at the tip portion 14 ′ of the ratchet 14. That is, the tip of the projection 21 on the inner side of the slide knob 19 is inserted into the long opening 4 of the other side 3 ′ of the frame 2, and the pin 22 is fixed to the support shaft 5. ing.

  The inner side of the fixed knob 20 is provided with a pair of upper and lower protrusions 23, 23 having a length and a gap that do not interfere with the sliding of the slide knob 19 in the axial direction with respect to the pair of concave grooves 24, 24. It is mated. This fitting is performed until the slide knob 19 is pushed by the ridge 25 and comes into contact with the retaining ring 26 fixed on the support shaft 5, that is, until the projection 21 of the slide knob 19 is inserted into the long opening 4 of the frame 2. It will not come off. The width of the protrusion 21 is slightly narrower than the width of the long opening 4.

  The slide knob 19 cannot rotate when the projection 21 is sandwiched between the inner widths of the long opening 4 of the frame 2. Therefore, since the concave grooves 24 and 24 and the fixed knob 20 are connected by the projections 23 and 23, the support shaft 5 fixed to the fixed knob 20 by the pin 22 does not rotate.

  In order to rotate the support shaft 5, first, the slide knob 19 is rotated while maintaining the state of sliding in the axial direction until the protrusion 21 escapes from the long opening 4 against the ridge 25. Then, the fixed knob 20 having the protrusions 23 and 23 fitted to the concave grooves 24 and 24 of the slide knob 19 rotates to rotate the support shaft 5 fixed by the pin 22 by being driven to rotate. (See Figure 8)

  The rotation direction of the support shaft 5 is clockwise in FIG. At the time of one rotation, the protrusion 21 is pushed by the ridge 25 and inserted into the long opening 4, and the rotation stops. At this point, the stamping position of the foil returns to zero.

  (2) Zero return of foil

  For example, FIG. 5 shows the stamped state of the number 1 (the wheel 6 has been rotated clockwise by one number from the zero-returned state of FIG. 4). When the support shaft 5 rotates clockwise, the tip end portion 14 ′ of the ratchet 14 slides down the inclined surface 16 of the support shaft 5 and hits the face 18.

  Further, as the support shaft 5 rotates in the clockwise direction, the wheel 6 also moves in the clockwise direction via the pin 13 of the ratchet 14 pressed against the face 18 of the support shaft 5.

When the foil 6 is rotated in the clockwise direction by the return zero operation, the feeding claw 8 has the inclined surface portion 11 of the gear 7 pushed back against the pressure of the ridge not shown in the drawing so that the claw shaft 9 is moved. Turns counterclockwise around the center and escapes.

  The clockwise rotation of the support shaft 5 is stopped when the projection 21 of the slide knob 19 is inserted into the long opening 4.

  By making one rotation of the support shaft 5, the foils of all the digits are set to zero (the number at the stamp position is 0).
