Utility Model Registration No.3054580

  By the way, in the braille embossing device, in order to obtain an embossing convex portion having a desired height (for example, 0.4 mm), the embossing height of the embossing pin with respect to the braille sheet is set to a predetermined value (for example, 0.65 mm to 0.65 mm). 0.70 mm). However, in the conventional braille stamping device, in order to assemble the stamping pin and the solenoid accurately so that the stamping height of the stamping pin with respect to the braille sheet becomes a predetermined value, the maximum protruding state (magnetic core of the movable iron core) is required. It is necessary to adjust so that the stamping pin in the (attached state) is at a predetermined position with respect to the sheet feed path surface, and the assembly work of the stamping pin and the solenoid is complicated.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a braille stamping device that can easily assemble a stamping pin and a solenoid and can stamp a stamping convex portion having a desired height.

The braille marking device of the present invention includes a stamping pin for stamping a stamping convex portion on a braille sheet, a solenoid for performing a stamping operation by moving the stamping pin forward and backward with respect to the braille sheet, and a stamping pin. A regulating member that regulates the forward end position, and when the stamping pin is in the forward end position, the solenoid regulating member so that the movable iron core of the solenoid is positioned before the suction moving end position by the fixed iron core The relative position with respect to is set.
And it is preferable that the attraction | suction movement end position of a movable iron core is a position magnetically attached to a fixed iron core.

According to this configuration, when the solenoid is attached to the set position, when the advancement of the punching pin accompanying the suction movement of the movable iron core is restricted by the restriction member, the suction movement of the movable iron core is the suction movement end. It will stop before the position. That is, the stamping pin can be advanced to the forward end position only by moving the movable iron core to a position before the suction movement end position.
On the other hand, if the solenoid is assembled away from the regulating member in the operation direction than the set position, the stamping pin is also separated from the regulating member, but the movable iron core is moved to the suction moving end position or close to it. The amount of stroke of the stamping pin can be increased, and the stamping pin can be advanced to the forward end position. For this reason, the stamping height of the stamping pin with respect to the braille sheet does not become smaller than a predetermined value. In addition, when the solenoid is assembled closer to the restricting member than the set position, the embossing pin also approaches the restricting member, but when the movable iron core moves to a position just before the suction moving end position, the embossing pin moves closer. The forward movement of the pin is regulated by the regulating member. For this reason, the stamping height of the stamping pin with respect to the braille sheet does not become larger than a predetermined value.
From the above, even if the solenoid is assembled back and forth from the set position, the stamping pin moves forward to the forward end position, so the stamping height of the stamping pin with respect to the braille sheet is managed to a predetermined value. Can do. In addition, even if the power transmission system (link mechanism) from the solenoid to the stamping pin is worn, the stamping pin advances in the same way to the forward end position, so the stamping height of the stamping pin with respect to the braille sheet Can be managed to a predetermined value. Therefore, it is possible to stamp a stamping convex part with a desired height regardless of secular changes such as the assembly accuracy of the solenoid or wear of the power transmission system, and the solenoid and stamping pin to the braille stamping device can be stamped. Assembly work can be performed easily and in a short time.

  In this case, there is further provided a link mechanism that transmits to the stamping pin the attraction movement of the movable iron core accompanying excitation and the return movement of the movable iron core accompanying demagnetization, and between the movable iron core and the link mechanism, and the stamping pin, It is preferable that a spring is interposed between the link mechanism and the link mechanism.

According to this configuration, even when the solenoid is attached to the set position, or even when the solenoid is attached closer to the regulating member than the set position, the suction moving end position can be obtained by providing the spring. The movable iron core that has moved to the position before the end moves further to the suction movement end position without stopping there. Therefore, the driving force of the solenoid can always be used effectively.
When a spring (tensile spring) is interposed between the movable iron core and the link mechanism, the movable iron core moves to the suction movement end position while pulling the spring with excitation. On the other hand, when a spring (compression spring) is interposed between the embossing pin and the link mechanism, the movable iron core moves to the suction moving end position while compressing the spring with excitation.

  Another braille stamping device of the present invention includes a stamping pin that stamps a stamping convex portion on a braille sheet, a solenoid that performs a stamping operation by moving the stamping pin forward and backward with respect to the braille sheet, and a stamping A regulating member that regulates the forward end position of the pin, and by restricting the forward end position of the stamping pin, the movement of the movable iron core that is attracted to the fixed iron core of the solenoid is regulated, A relative position of the solenoid with respect to the regulating member is set.

  According to this configuration, when the solenoid is attached to the set position, the movement of the movable iron core is regulated by the regulation member regulating the advancement of the stamping pin accompanying the suction movement of the movable iron core. . In other words, when the advancement of the stamping pin is restricted, the movable iron core is in a state in which there remains a remaining force to move to the suction movement end position. Therefore, when the solenoid is attached to the restricting member away from the set position, the stamping pin is also separated from the restricting member, but the movable iron core is moved to the suction moving end position or close to it (see above). By using the remaining force), the amount of stroke of the stamping pin can be increased, and the stamping pin can be advanced to the forward end position. Therefore, similarly to the above configuration, a stamping convex portion having a desired height can be stamped regardless of secular changes such as solenoid assembly accuracy and power transmission system wear. Assembling work of the solenoid and the stamping pin can be performed easily and in a short time.

  In these cases, there is further provided a stamp receiving member having a stamp receiving recess formed on the surface facing the stamp pin across the braille sheet so that the head of the advancing stamp pin abuts. Preferably also serves as a regulating member.

According to this configuration, by providing the stamp receiving member, the shape of the stamped convex portion can be made favorable. Since the stamp receiving member also serves as a restricting member, the forward end position of the stamp pin can be restricted with a simple configuration, and the number of parts of the entire apparatus is not increased.
In this case, the forward end position of the embossing pin is a position where the head of the embossing pin comes into contact with the inner surface of the embossing receiving recess with the braille sheet interposed therebetween.

  In these cases, it is preferable to further include printing means for printing ink characters on the braille sheet.

  According to this configuration, in addition to being able to imprint Braille on a Braille sheet, it is possible to print ink characters, and thus it is possible to produce a variety of labels.

Control the time stamping.

  Here, the embossing unit 42 will be described in detail with reference to FIGS. 4, 6 and 7. The embossing unit 42 corresponds to the three embossing protrusions 201 in the column among the six embossing protrusions 201, the three embossing mechanisms 51 each having the embossing pins 61, and the Braille tape T. A stamping pin guide 52 in which three guide holes 53 for guiding the advancement and retraction of each stamping pin 61 are formed, and a stamp receiving member 54 that receives the pushing up of each stamping pin 61 across the Braille tape T are provided. Yes. When the Braille tape T is introduced between the stamping pin 61 and the stamp receiving member 54 from the tape running path 41, the stamping pin 61 is selectively driven from the back side (release sheet side), and the Braille B A stamping convex portion 201 is formed on the surface. Note that the three stamping pins 61 are positioned along the width direction of the tape running path 41 (the direction perpendicular to the tape feed direction) and the lower end in the vertical direction perpendicular to the tape feed direction (in FIG. 2). , A position close to the left end portion), and Braille stamping is performed on the lower end portion of the Braille tape T.

  Each stamping mechanism 51 includes a stamping pin 61, a solenoid 62 serving as a driving source, an arm member 63 that connects a tail end portion 61b of the stamping pin 61 and a movable iron core 72 (plunger) of the solenoid 62. The arm member 63 includes a support member 64 that rotatably supports the arm member 63 at a position slightly closer to the punching pin 61 (rotation center 63a) than the intermediate portion thereof, and a frame piece 65 that supports the solenoid. Of the three arm members 63, two arm members 63 positioned above and below the braille tape T extend so as to be separated from each other in the tape width direction, and the remaining one arm member 63 is the braille tape T. It extends along the feed direction. That is, the three arm members 63 extend in three directions from the position of the stamping pin 61, and as a result, the three solenoids 62 are arranged to form a triangle.

  The solenoid 62 is screwed to the frame piece 65 by a fixing screw 66, thereby constituting the above-described stamping assembly (see FIG. 6), and a substantially cylindrical casing 71 constituting the outer shell; The fixed iron core 73 (core), which is disposed along the inner peripheral surface of the casing 71 and wound with a coil (not shown), is loosely inserted into the fixed iron core 73, and one end is exposed from the upper surface of the casing 71. And a pull-type one having a movable iron core 72. That is, the movable iron core 72 is attracted to the fixed iron core 73 with excitation, and the movable iron core 72 is returned to its original position by a return spring (not shown) with demagnetization. The magnetic pole 73 a of the fixed iron core 73 also serves as a stopper for the movable iron core 72, and the magnetic pole 72 a of the movable iron core 72 is magnetically attached to the magnetic pole 73 a of the fixed iron core 73, thereby restricting its attraction movement. It is like that. That is, the original suction movement end position of the movable iron core is a position where it is magnetically attached to the fixed iron core 73. Of course, a silencer type that does not directly contact the fixed iron core 73 even when the movable iron core 72 is sucked may be used. In this case, the suction movement end position of the movable iron core 72 is the same as that of the fixed iron core 73. It becomes a position with a gap.

  A rated pulse voltage is applied to the solenoid 62 (coil), and the applied voltage is set to a rated value (for example, 18 V) so as to give an appropriate stamping force to the stamping pin 61. . In the present embodiment, a voltage is applied with a time difference to the three solenoids 62 in order to reduce the power supply capacity.

  The stamping pin 61 is made of stainless steel or the like, and its stamping tip 61a (head) is formed in a hemispherical shape. The embossing pin 61 is disposed in parallel with the movable iron core 72 (parallel to the vertical direction) and in the direction opposite to the suction movement direction of the movable iron core 72 (upward in the drawing) with the embossing tip 61a facing. Yes. The arm member 63 has one end abutting (semi-fixedly connected) to the tail end portion 61 b of the stamping pin 61 and the other end rotatably connected to the tip end portion of the movable iron core 72 of the solenoid 62. The link mechanism is configured to transmit the attraction movement of the movable iron core 72 by excitation of the solenoid 62 and the return movement of the movable iron core 72 by demagnetization to the embossing pin 61. That is, as the movable iron core 72 is attracted and moved (excited), the end of the arm member 63 on the movable iron core 72 side is moved downward and the end on the stamping pin 61 side is moved upward. The punching pin 61 is advanced (pushed up) toward the Braille tape T by rotating around the center 63a. Further, with the return movement (demagnetization) of the movable iron core 72, the end of the arm member 63 on the movable iron core 72 side is moved upward and the end of the stamping pin 61 side is moved downward by the return spring. Then, the punching pin 61 is retracted from the Braille tape T by rotating about the rotation center 63a.

  The stamp receiving member 54 is used to receive a stamp on the Braille tape T by the stamp pin 61, and is formed of a thick aluminum plate or the like, and is screwed and fixed onto the frame (tape running path 41). Yes. The stamped surface 76 facing the three stamping pins 61 has three stamp receiving recesses 77 arranged at equal intervals corresponding to the three stamping pins 61. Each embossing recess 77 is formed in a shape (hemispherical shape) substantially complementary to the embossing tip 61a of the embossing pin 61, and the radius D of the hemisphere formed by the inner surface 77a is a predetermined value. (For example, 0.7 mm) is formed with high accuracy. The stamping pin 61 has its stamping tip 61a abutting against the inner surface 77a of the stamping recess 77 with the Braille tape T in between, so that its forward end position is regulated. In addition, the structure which regulates the advance end position of the stamping pin 61 by providing an annular stepped portion or a flange on the tail end portion 61 b of the stamping pin 61 and abutting against a part of the guide hole 53 may be adopted. .

  Then, as described above, when the braille tape T is fed using the embossing feed motor 43 as a drive source and the solenoid 62 is driven based on the braille data from the control unit 107 in synchronism with this, the embossing pin 61 and the embossing pin are driven. The Braille tape T introduced between the engraving member 54 is engraved from the back side by the engraving pin 61 to form the engraving convex portion 201 on the surface.

  Here, the relative position of the solenoid 62 with respect to the stamp receiving member 54 will be described with reference to FIG. The relative position of the solenoid 62 with respect to the stamp receiving member 54 is such that the stamp tip 61a of the stamp pin 61 is in contact with the inner surface 77a of the stamp receiving recess 77 with the Braille tape T interposed therebetween (at the forward end position). At this time, the movable iron core 72 of the solenoid 62 is set to be positioned in front of the suction movement end position by the fixed iron core 73.

  FIG. 4A shows a state where the solenoid 62 is assembled at the set position. In this case, when the advancement of the punching pin 61 accompanying the suction movement of the movable iron core 72 is restricted by the stamp receiving member 54, the position (suction) where the suction movement of the movable iron core 72 is magnetically attached to the fixed iron core 73. Stops before (moving end position). That is, only by moving the magnetic pole 72 a of the movable iron core 72 to a position before the magnetic pole 73 a of the fixed iron core 73, the embossing pin 61 moves forward to the inner surface 77 a of the embossing receiving recess 77. In other words, the movement of the movable iron core is restricted by the stamp receiving member 54 restricting the advancement of the punching pin 61 accompanying the suction movement of the movable iron core 72. And when advance of the embossing pin 61 is controlled, it can be said that the movable iron core 72 is in a state in which the remaining force to move to the suction moving end position remains.

FIG. 4B shows a state in which the solenoid 62 is assembled further away from the stamp receiving member 54 than the set position. In this case, the stamping pin 61 is also separated from the stamp receiving member 54 as compared with the case of FIG. (A), so that the stamping pin 61 is advanced to the forward end position (the inner surface of the stamp receiving recess 77). It is necessary to increase the advance / retreat stroke amount of the embossing pin 61. However, by moving the movable iron core 72 to a position where it is magnetically attached to the fixed iron core 73, the advance / retreat stroke amount of the embossing pin 61 can be increased. it can. In other words, by using the remaining power of the movable iron core 72, it is possible to increase the amount of stroke of the stamping pin. Therefore, also in this case, the stamping pin 61 moves forward to the inner surface 77 a of the stamp receiving recess 77.
Further, even when wear occurs in the link mechanism from the solenoid 62 to the stamping pin 61, by moving the movable iron core 72 to a position where it is magnetically attached to the fixed iron core 73, the amount of wear can be reduced. Therefore, the stamping pin 61 advances to the inner surface 77a of the stamp receiving recess 77.

  FIG. 5C shows a state where the solenoid 62 is assembled closer to the stamp receiving member 54 than the set position. In this case, as compared with the case of FIG. (A), the stamping pin 61 also comes closer to the stamping receiving member 54, so that the stamping pin 61 is moved forward by the stamping movement of the movable iron core 72 by the stamping receiving member 54. When restricted, the movable iron core 72 stops at a position where there is a considerable gap from the fixed iron core 73. In other words, the stamping pin 61 advances to the inner surface 77 a of the stamp receiving recess 77 only by moving the movable iron core 72 to a position substantially before the fixed iron core 73.

  As described above, even when the solenoid 62 is assembled back and forth from the set position, the stamping pin 61 moves forward to a position where it contacts the inner surface 77a of the stamp receiving recess 77 with the Braille tape T interposed therebetween. The stamping height of the stamping pin 61 with respect to T is managed by the value of the radius D of the stamp receiving recess 77. Therefore, the stamping convex portion 201 having a desired height H can be stamped regardless of the secular change such as the assembly accuracy of the solenoid 62 or the wear of the link mechanism, and the solenoid 62 to the frame of the stamping assembly and The assembling work of the stamping pin 61 can be performed easily and in a short time.

  Further, since the stamp receiving member 54 also serves as a regulating member that regulates the forward end position of the stamp pin 61, the forward end position of the stamp pin 61 can be restricted with a simple configuration, and the device The total number of parts does not increase.

  Further, as shown in FIG. 7A, a tension spring 81 may be interposed between the movable iron core 72 and the arm member 63. According to this, the solenoid 62 is assembled at the set position. In this case, or even when assembled near the stamp receiving member 54 rather than the set position, the movable iron core 72 moves to the fixed iron core 73 while pulling the tension spring 81 with the excitation. Similarly, a compression spring 82 may be interposed between the embossing pin 61 and the arm member 63 as shown in FIG. 5B, and according to this, the solenoid 62 is assembled at the set position. In the case where it is present, or when it is assembled closer to the stamp receiving member 54 than the set position, the movable iron core 72 moves to the fixed iron core 73 while compressing the compression spring 82 with the excitation. Therefore, the driving force of the solenoid 62 can always be used effectively, and the rated value of the voltage applied to the solenoid 62 can be set low.

  As described above, the label producing apparatus 1 according to the embodiment includes the braille embossing unit 104 to which the present invention is applied, so that the embossing pin 61 and the solenoid 62 can be easily assembled and have a desired height. The stamping convex portion 201 can be stamped.
