TECHNICAL FIELD OF THE INVENTION
The present invention relates to an automatic stamping device, and more particularly to an automatic stamping device for automatically applying ink to a seal.
[0002]
[Prior art]
Conventionally, in order to certify the contents of various certificates, a seal corresponding to the various certificates is stamped after describing the contents of the certificates and the date of issuance. However, since the stamping of the seal is performed mainly by hand manually, it requires a considerable work time and labor, resulting in a decrease in service and an increase in cost. In addition, there is a case where a difference occurs in the quality of the imprint imprinted by manual operation. In order to solve such a problem, studies have been made on an automatic stamping apparatus for the purpose of speeding up the stamping operation and making the quality of the imprint uniform.
[0003]
Automatic stamping devices are roughly classified into two types. The first method uses a conventional seal that is commercially available or the like, and seals the seal by reciprocating mainly in the vertical direction. In the second method, a stamping roller is used instead of a seal stamp, and stamping is performed by rotating the stamping roller. For the purpose of high-speed stamping, an automatic stamping apparatus using the second method is generally being studied (for example, Patent Document 1).
[0004]

[Problems to be solved by the invention]
Under such circumstances, the inventor has come to recognize the following problem. When automating the manual stamping work in the degree diploma in addition to the certificate as it is, it is necessary to ensure the minimum quality of the stamp imprinted by hand. It is more desirable to be able to use the stamp that you have just received. Further, with respect to the ink, it is more preferable to use vermilion as before, in consideration of the durability of the ink over time. The main components of vermilion are, for example, mercury, castor oil, vermilion powder, and the like, which cause the vermilion to become viscous, which causes unevenness when applied to a seal and tends to make the quality of the imprint uneven. However, in the conventional stamping work, fine adjustments have been made manually to prevent unevenness.
[0006]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide an automatic stamping device that can use a seal. Another object of the present invention is to provide an automatic stamping device for uniformly applying ink to a seal. Another object of the present invention is to provide an automatic imprinting apparatus capable of providing imprints of uniform quality even when the ink has viscosity.
[0007]
[Means for Solving the Problems]
One embodiment of the present invention relates to an automatic stamping device. This device supports the seal with the seal surface facing down, raises and lowers the supported seal, and seals the stamped body at the position where the seal is most lowered, and provides ink to the seal. An ink providing unit that supports the ink base, a first position for absorbing the ink from the ink base, and a second position for applying the absorbed ink to the imprint surface of the seal. Ink reciprocating means that reciprocates by relative movement with the imprinting means.
[0008]
The ink providing means supports the ink base with the ink surface facing down, raises and lowers the supported ink base, and raises the ink surface at a first position set at the same height as the second position. When brought into contact with the ink mediating means, the ink mediating means may reciprocate in a substantially horizontal direction between the first position and the second position. Further, the ink supply unit may raise and lower the ink table supported in synchronization with the stamping unit.
[0009]
With regard to “synchronization”, it is not necessary that the ink supply unit and the stamping unit are completely synchronized, and even if they are not synchronized, it is sufficient that a predetermined regularity exists between them.
According to this apparatus, the ink on the ink base is applied to the imprint surface via the ink mediating means.
[0010]
Another embodiment of the present invention also relates to an automatic stamping device. This device supports the seal with the seal surface facing down, raises and lowers the supported seal, and seals the stamped body at the position where the seal is most lowered, and provides ink to the seal. So that the ink supply means for supporting the ink table, the first surface for absorbing the ink from the ink table, and the second surface for applying the absorbed ink to the imprint surface of the seal are alternately changed. , An ink supply unit, and an ink mediating unit that rotates by relative movement with respect to the stamping unit.
[0011]
The ink providing means supports the ink base with the ink surface facing upward, reciprocates the supported ink base in a substantially horizontal direction, and moves the ink surface to the second position at the application position where the ink surface faces the imprint surface. The first surface may be brought into contact with the first surface, and the ink mediating means may reciprocate in a substantially horizontal direction to bring the second surface into contact with the imprint surface at the application position. Further, the ink providing means may reciprocate the ink table supported in synchronization with the ink mediating means in a substantially horizontal direction.
[0012]
The "rotation of the ink mediating means" may be executed at the application position, or may be executed at a position other than the application position.
According to this apparatus, the ink mediating unit executes the operation of absorbing ink from the ink base and the operation of providing ink to the seal as one operation.
[0013]
Yet another embodiment of the present invention also relates to an automatic stamping device. This device supports the seal with the imprint surface facing down, raises and lowers the supported seal, and seals the stamped body at the position where the seal is most lowered, and provides ink to the seal. And an ink providing means for absorbing the ink from the ink base and applying the absorbed ink to the imprint surface of the seal. In this apparatus, at a timing other than the period of imprinting on the object to be imprinted by the imprinting means, the imprinting means, the ink mediating means, and the ink providing means perform relative movement so as to be located on the vertical line in this order, and after the relative movement, the imprinting is performed. Means and the ink supply means simultaneously press the ink mediating means from above and below, so that the absorption of ink from the ink base to the ink absorber and the application of ink from the ink absorber to the seal are performed in a single operation. Good.
[0014]
An example of the “ink absorber” is a sponge, but the thickness may be arbitrary and may be thin.
According to this apparatus, since the absorption of the ink from the ink base to the ink absorber and the application of the ink from the ink absorber to the seal are performed in a single operation, the speed of the stamping operation can be increased. In addition, since the number of movable parts can be reduced, the durability of the device is improved.
[0015]
Yet another embodiment of the present invention also relates to an automatic stamping device. This device supports the seal with the seal surface facing down, raises and lowers the supported seal, and seals the stamped body at the position where the seal is most lowered. Ink providing means for supporting an ink table for supplying ink to the ink, a first surface for absorbing the ink from the ink table, and a second surface for applying the absorbed ink to the imprint surface of the seal. Mediation means. In this apparatus, the imprinting means contacts the first surface with the ink table while contacting the second surface at the application position where the ink mediating means and the ink providing means continuously overlap in the downward direction. When the seal is imprinted, the seal means moves in a substantially horizontal direction from the application position and rotates so as to alternately change the first surface and the second surface. Alternatively, it may be moved substantially horizontally from the application position.
In addition, any combination or rearrangement of the above-described constituent elements, and those expressing the present invention as a method, a computer program, and the like are also effective as embodiments of the present invention.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
(Embodiment 1)
The automatic stamping device according to the first embodiment relates to a device that applies a viscous ink such as vermilion ink to a seal imprint surface of a seal stamp, and stamps a predetermined sheet with the seal stamp. In this embodiment, a water-absorbing substance such as a sponge is brought into contact with the vermilion so that the sponge absorbs the liquid component of the vermilion ink. Further, the sponge is brought into contact with the imprint surface of the seal to apply the liquid component of the ink to the imprint surface. As described above, since only the liquid component of the ink is applied to the imprint surface of the seal using the sponge as a medium, unevenness in the imprint can be reduced. Further, the above operation can be realized by a device that reciprocates the seal and the vermilion in the elevating direction and the sponge in the horizontal direction, respectively, so that the configuration is simplified.
[0017]
FIG. 1 shows a configuration of the automatic stamping apparatus 100 according to Embodiment 1 as viewed from the front. The automatic stamping device 100 includes a seal 10, a seal support 18, a vermilion 14, a vermilion support 20, a horizontal support 22, a seal reciprocating part 24, a vertical support 26, a sponge 16, a sponge support 28, and a horizontal moving rail 30. , A first motor 34, a second motor 36, and a control unit 38.

The sponge 16 is formed of a material having a water-absorbing property, and serves as a medium for applying the liquid component of the ink on the ink surface 40 to the imprint surface 12.
The sponge support portion 28 has the sponge 16 disposed at an upper portion, and reciprocates in a horizontal direction along the horizontal movement rail 30 on the horizontal movement rail 30 together with the sponge 16. The moving distance for reciprocating in the horizontal direction depends on the length of the horizontal moving rail 30, but is designed to include at least a position where the sponge 16 is below the ink surface 40 and below the imprint surface 12.
[0022]
The first motor 34 is a motor for automatically reciprocating the seal reciprocating unit 24 in the elevating direction, and the second motor 36 is a motor for automatically reciprocating the sponge support unit 28 in the horizontal direction. The timing control is performed by the control unit 38.
[0023]
FIG. 3 shows a flowchart of the stamping operation by the automatic stamping device 100. If there is a sheet 32 to be stamped by the seal 10 (Y in S10), the sponge 16 is moved below the vermilion 14 (S12). This state is shown in FIG. While maintaining this horizontal positional relationship, the seal reciprocating unit 24 is lowered to bring the vermilion meat 14 into contact with the sponge 16 (S14). FIG. 4B shows this state. At this time, the sponge 16 absorbs the ink from the red meat 14. The seal reciprocating part 24 is raised again to separate the vermilion meat 14 and the sponge 16 (S16). This state is shown in FIG.
[0024]
The sponge support 28 moves the sponge 16 horizontally below the seal 10 (S18). This state is shown in FIG. While maintaining this horizontal positional relationship, the seal reciprocating part 24 is lowered to bring the seal 10 into contact with the sponge 16 (S20). This state is shown in FIG. 4E. At this time, the sponge 16 applies ink to the imprint surface 12. The seal reciprocating part 24 is raised again to separate the seal 10 from the sponge 16, and the sponge 16 is horizontally moved between the vermilion 14 and the seal 10 (S22). This state is shown in FIG. Finally, the seal 10 stamps the paper 32 by re-lowering of the seal reciprocating unit 24 (S24). This state is shown in FIG. When there is no more paper 32 to be stamped (N in S10), the above operation ends.
[0025]
FIG. 5 shows a time chart of the stamping operation performed by the automatic stamping apparatus 100. The vertical axis in the figure indicates the distance between the seal 10 and the paper 32 as illustrated in FIG. 4A, and the horizontal axis indicates the elapsed time of the stamping operation. P1 corresponds to FIG. 4A, and P2 corresponds to FIG. 4B. Hereinafter, the same correspondence is repeated from P3 to P7. These are the ink absorbing operations in which the sponge 16 comes into contact with the vermilion 14 three times in a row. P8 corresponds to FIG. 4D, and P9 corresponds to FIG. 4E. Hereinafter, the same correspondence is repeated from P10 to P14. These are coating operations in which the sponge 16 contacts the seal 10 three times in a row. P15 corresponds to FIG. 4 (f), and P16 corresponds to the stamping operation corresponding to FIG. 4 (g).
[0026]
An outline of the operation of the automatic stamping apparatus 100 having the above configuration is as follows. The seal reciprocating part 24 is repeatedly moved up and down, and the vermilion 14 and the seal 10 are moved up and down at the same time. On the other hand, the sponge 16 repeatedly reciprocates in the horizontal direction. When the sponge 16 is located below the vermilion 14, it absorbs ink from the vermilion 14. I do. When the sponge 16 is located between the seal 10 and the vermilion 14, the seal reciprocating part 24 descends most, and the seal 10 stamps the paper 32.
[0027]
According to the present embodiment, even when using an ink base having a viscosity like vermilion, only the liquid component of the ink in vermilion is once absorbed by the sponge, and the absorbed liquid component of the ink is imprinted on the seal surface of the seal. Since it is applied to the surface of the seal, the unevenness of the seal can be reduced and the quality of the seal can be made uniform. Further, even when the ink is difficult to apply because the corners of the imprint surface are worn down, only the liquid component of the ink is applied, so that the ink can be applied uniformly. Further, the configuration can be facilitated because it can be realized by a combination of the reciprocating operation in the vertical direction and the horizontal direction.
[0028]
(Embodiment 2)
The automatic stamping device according to the second embodiment is similar to the automatic stamping device according to the first embodiment, in which a viscous ink such as vermilion is applied to the imprint surface of the seal, and the stamp is applied to a predetermined sheet. It relates to a device for imprinting. In the first embodiment, the step of absorbing the ink with the sponge and the step of applying the ink to the imprint surface are operated as separate steps. On the other hand, in the second embodiment, since these two steps are executed simultaneously, that is, they operate substantially as one step, the speed of the stamping operation can be increased.
[0029]
FIG. 6 shows a configuration of the automatic stamping apparatus 100 according to Embodiment 2 as viewed from the front. The automatic stamping device 100 includes a seal 10, a seal support 18, a vermilion 14, a seal reciprocating part 24, a vertical support 26, a sponge 16, a sponge support 28, a horizontal moving rail 30, a first motor 34, and a second motor 36. , A control unit 38, and a rotation unit 42. FIG. 7 shows the configuration of the automatic stamping device 100 from the side, but does not show the first motor 34, the second motor 36, and the control unit 38 here. Hereinafter, portions different from FIG. 1 will be described.
[0030]
The seal reciprocating unit 24 reciprocates the seal support unit 18 and the seal 10 in the elevating direction. The sponge support portion 28 has the vermilion 14 and the sponge 16 arranged on the upper portion, and reciprocates in the horizontal direction along the horizontal moving rail 30 on the horizontal moving rail 30 together with the vermilion 14 and the sponge 16. Further, an elastic body such as a spring is attached in order to secure elasticity when the sponge 16 is pressed from above. Further, the moving distance for reciprocating in the horizontal direction depends on the length of the horizontal moving rail 30, but is designed to include at least a position where the sponge 16 is below the imprint surface 12. The vermilion 14 is supported such that the ink surface 40 faces upward, unlike FIG.
[0031]
The rotating unit 42 is fixed to the sponge support unit 28, and rotates the sponge 16 so that the upper surface and the lower surface of the sponge 16 are alternately exchanged. In order to rotate the sponge 16, there is a rotating mechanism constituted by a horizontal axis. The rotation of the rotating unit 42 is performed by converting the power of the second motor 36 into a rotational motion using a hinge or the like.
[0032]
FIG. 8 shows a flowchart of the stamping operation performed by the automatic stamping device 100. If there is a sheet 32 to be stamped by the seal 10 (Y in S30), the vermilion 14 and the sponge 16 are moved below the seal 10 (S32). This state is shown in FIG. While maintaining this horizontal positional relationship, the seal reciprocating part 24 is lowered to bring the vermilion 14 into contact with the sponge 16 and the sponge 16 with the seal 10. FIG. 9B shows this state. At this time, the ink of the red meat 14 is absorbed from the lower surface of the sponge 16, and the ink is applied to the seal 10 from the upper surface (S34).
[0033]
The seal reciprocating part 24 is raised again, and the vermilion meat 14 and the sponge 16 are further moved horizontally from below the seal 10 (S36). At that time, the rotating unit 42 rotates the sponge 16 by 180 degrees such that the upper surface and the lower surface of the sponge 16 are alternately changed. This state is shown in FIG. Finally, the seal 10 stamps the paper 32 by re-lowering of the seal reciprocating part 24 (S38). This state is shown in FIG. When there is no more paper 32 to be stamped (N in S30), the above operation is terminated.
[0034]
FIG. 10 shows a time chart of the stamping operation performed by the automatic stamping apparatus 100. The vertical axis of the figure indicates the distance between the seal 10 and the paper 32 as exemplified in FIG. 9A, and the horizontal axis indicates the elapsed time of the stamping operation. P1 corresponds to FIG. 9A, and P2 corresponds to FIG. 9B. Hereinafter, the same correspondence is repeated from P3 to P7. These are an ink absorbing operation in which the sponge 16 contacts the vermilion 14 three times in a row and an application operation in which the sponge 16 contacts the seal 10 three times in a row. P8 corresponds to FIG. 9C, and P9 corresponds to the stamping operation corresponding to FIG. 4D.
[0035]
An outline of the operation of the automatic stamping apparatus 100 having the above configuration is as follows. The seal reciprocating part 24 is repeatedly moved up and down, and the seal 10 is also moved up and down repeatedly. On the other hand, the red meat 14 and the sponge 16 repeatedly reciprocate in the horizontal direction, and when the sponge 16 is located below the seal 10, the upper surface of the sponge 16 contacts the seal 10 to apply ink to the seal 10 and the lower surface thereof. The ink is absorbed from the red meat 14. In addition, when the vermilion 14 and the sponge 16 are not located below the seal 10, the sponge 16 rotates so that the upper surface and the lower surface are switched. Further, the seal reciprocating portion 24 descends most, and the seal 10 stamps the paper 32.
[0036]
According to the present embodiment, in the case of using an ink table having a viscosity like vermilion, an operation of temporarily absorbing only the liquid component of ink in vermilion into a sponge, and imprinting the absorbed liquid component of ink on a seal. Since the operation of applying to the surface can be performed at the same time, it is possible to prevent the consumption of time due to the mediation of the sponge, and to reduce the time for the stamping operation.
[0037]
The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and that such modifications are also within the scope of the present invention. . Here are some examples.
[0038]
In Embodiments 1 and 2, vermilion 14 is used as the ink base. However, the ink is not limited to the vermilion and other types of ink may be used. In particular, the present invention is effective when the ink has a certain degree of viscosity. According to this modification, the present invention can be widely applied.
[0039]
In Embodiments 1 and 2, the seal 10 is used. However, for example, a stamp roller may be used, the shape of the seal is not particularly limited, and the seal 10 may not be the seal 10 in which the corners of the imprint surface 12 are worn. This modification is effective for the difference in applying vermilion 14 to the stamping roller.
[0040]
In the first and second embodiments, the contact between the red meat 14 and the sponge 16 and the contact between the sponge 16 and the seal 10 are continuously performed three times. However, this does not have to be performed three times, and the stamping operation by the seal 10 may be continuously performed a plurality of times. According to this modification, the speed of the stamping operation is increased. That is, it is only necessary that the quality of the stamped seal satisfies the desired quality.
[0041]
In the second embodiment, the second motor 36 and the hinge are used in order for the rotating unit 42 to perform the rotating motion. However, other combinations may be used. For example, the rotation of the rotating unit 42 may be generated by a new third motor.
