[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rotation mark in which a master printing body is provided at a lower end of a rotation printing body having a plurality of printing belts, and the rotation printing body for making the printing surface of the printing belt and the master printing body the same surface. The present invention relates to a rotation mark having a height adjusting mechanism.
[0002]
[Prior art]
Conventionally, this type of rotation mark is well known and disclosed in, for example, Japanese Utility Model Publication No. 64-4532 and Japanese Utility Model Application No. 1-226460. When this type of rotation mark is assembled, in most cases, the print belt and the master print body have a slight deviation in the height of the print surface, and the print surface does not become the same surface. Even if the seal is printed with, the imprint becomes uneven and a clear seal cannot be obtained. In addition, when the printing surface is changed by rotating the printing belt, the printing surface of the same belt before the change and the printing surface of the master printing body may not be the same or may be used for a long time. In addition, the print surface of the print belt and the print surface of the master print body are worn out, and the print surface of the print belt and the master print body are not the same surface. Sometimes you can't. In view of this, a rotation mark as disclosed in Japanese Utility Model Publication No. 64-4532, Japanese Utility Model Publication No. 1-246060, etc., is a printing belt in which the printing surface of the printing belt and the master printing body are the same surface. A height adjustment mechanism is provided.
[0003]
[Problems to be solved by the invention]
However, the conventional height adjusting mechanism has the following problems. That is, in the rotation mark of Japanese Utility Model Publication No. 64-4532, an adjustment nut is screwed onto a screw rod erected on the upper surface of the portal frame of the printing mechanism, and the printing mechanism is rotated by rotating the adjustment nut. The height of the print belt can be adjusted by moving up and down, and this rotation mark adjustment nut is always hidden inside the handle that is screwed onto the screw rod, making it impossible to rotate. It is what. Therefore, when the height of the print belt is adjusted at this rotation mark, the pattern must be rotated and removed each time, or the handle must be rotated to a position where the adjustment nut can be rotated, and the screw must be loosened. Therefore, there is a problem that the operation until the height adjustment of the print belt is troublesome. In addition, since the adjustment nut of the rotation mark is small and difficult to rotate by hand, there is a problem that a tool for rotating the adjustment nut is required when adjusting the height of the print belt.
[0004]
Next, in the rotation mark of No. 1-226460, the height of the print belt is adjusted with the same configuration as that of the rotation mark of No. 64-4532 described above, but the height screwed into the bolt is adjusted. An operation plate is attached to the adjustment nut for adjusting the height. The operation plate is normally crimped to the upper surface of the main body case by a handle screwed to the bolt so that it cannot be rotated. As a result, the adjustment nut cannot always rotate. Therefore, when performing height adjustment in such a rotation mark, it is not necessary to remove the handle, but it is necessary to rotate the handle to a position where the operation plate can be rotated and loosen the screw, There is a problem that the operation until the height adjustment is performed is troublesome in the same manner as the rotation mark of the aforementioned Japanese Utility Model Publication No. 64-4532. In this rotation mark, the operation plate is crimped to the upper surface of the main body case after adjusting the height, but when the operation plate is crimped to the upper surface of the main body case, the lower end of the handle rotates to the operation plate. However, when the operation plate is crimped, the operation plate may rotate together with the handle. This causes a deviation in the height of the print belt that should have been adjusted in height. There is a problem that it is difficult to make the printing surface of the master printing body the same surface.
[0005]
Further, in the conventional rotational mark disclosed in the above-mentioned Japanese Utility Model Publication No. 64-4532, Japanese Utility Model Publication No. 1-246060, etc., an adjustment nut and a handle are attached to a bolt (screw rod) erected on the upper surface of the frame at the time of assembly. However, the operation of screwing the adjusting nut and the handle is very troublesome at the time of assembling, and there is a problem that the assembling workability is poor.
[0006]
Therefore, the present invention solves the above-mentioned problems, makes it possible to easily adjust the height of the print belt without requiring an operation of rotating the handle many times to loosen the screw or removing the handle, In addition, it is possible to ensure that the print belt and the master print body have the same print surface so that there is no deviation in the print belt height immediately after the height adjustment, An object of the present invention is to provide a rotation mark that improves the workability of assembly by eliminating the need for screwing an adjusting nut or a handle at the time of assembly.
[0007]

If the master printing body 36 is lowered by loosening the belt, the print belt 8 can rotate smoothly without contacting the opening edge of the window hole 40 during rotation.
[0017]
Next, a method for adjusting the height of the print belt 8 of the rotation mark in the present embodiment will be described. In order to adjust the height of the print belt 8 so that the print surfaces of the print belt 8 and the master print body 39 are the same, the adjustment ring 18 may be rotated. First, as shown in FIG. 2, the upper end of the guide portion 10 is in contact with the lower surface of the adjustment ring 18, and the adjustment ring 18 is placed in a state where the guide portion 10 is positioned in the gap S of the adjustment ring 18 shown in FIG. When rotated in the direction, the upper end of the guide portion 10 starts to slidably contact the inclined portion 22. In the state where the upper end of the guide portion 10 is in contact with the lower surface of the adjustment ring 18 as shown in FIG. 2, the guide portion 10 is positioned in the gap S of the adjustment ring 18 shown in FIG. Even if the ring 18 is rotated in the same direction as the inclined portion 22 is inclined downward, the end surfaces on the lowest point 22a side of the two inclined portions 22 are in contact with the guide portion 10, and in this state, the adjusting ring 18 Cannot be rotated in the direction in which the inclined portion 22 is inclined downward.
[0018]
When the adjustment ring 18 is further rotated in one direction, the upper end of the guide portion 10 is slidably moved in the direction of the lowest point 22a of the inclined portion 22 in conjunction with the rotation. The frame 4 provided with is lowered against the elastic force of the elastic member 12. In this way, the frame 4 descends against the elastic force of the elastic member 12, so that the rotary mark 3 descends inside the main body case 1 against the elastic force of the elastic member 12, As a result, the print belt 8 can be lowered. When the adjustment ring 18 is rotated and the upper end of the guide portion 10 is positioned at the lowest point 22a of the inclined portion 22, the rotary stamper 3 is positioned at the lowermost portion, and the print belt 8 is positioned at the lowermost portion. It will be. Note that when the rotary stamp 3 is lowered against the elastic force of the elastic member 12, the elastic member 12 is in a compressed state, but the upper surface of the adjustment ring 18 and the flange 25 of the fixing member 19 Since the wave-like projections 29 and 30 provided on the lower surface are always meshed and the adjustment ring 18 is always rotated, even if the adjustment member 18 is released in the compressed state, the elastic ring 12 The member 12 is securely held in a compressed state, and the rotary stamp 3 does not rise arbitrarily.
[0019]
On the other hand, when the print belt 8 is raised, the adjustment ring 18 may be rotated in the direction opposite to that when the print belt 8 is lowered. Since the upper end of slidably moves in the direction of the gap S from the lowest point 22 a of the inclined portion 22, the rotary stamping body 3 rises due to the upward elastic force of the compressed elastic member 12. As a result, the print belt 8 can be raised. As shown in FIG. 2, when the upper end of the guide portion 10 comes into contact with the lower surface of the adjustment ring 18 and the guide portion 10 is positioned in the gap S of the adjustment ring 18 shown in FIG. 4, the elastic member 12 is compressed. As shown in FIGS. 1 and 2, the rotating stamper 3 is positioned at the uppermost position, and the print belt 8 is positioned at the uppermost position.
[0020]
The above is the method of adjusting the height of the printing belt 8 of the rotation mark in the present embodiment. In the present embodiment, since the dimension from the lower surface of the adjustment ring 18 to the lowest point 22a of the inclined portion 22 is 2.0 mm, the height adjustment of the print belt 8 should be performed within the range of 2.0 mm. Can do. In addition, the dimension from the lower surface of the adjustment ring 18 to the lowest point 22a of the inclined portion 22 is not limited to 2.0 mm. In addition, since the wave-like projections 29 and 30 provided on the upper surface of the adjustment ring 18 that are always in contact with each other and the lower surface of the flange portion 25 of the fixing member 19 are always meshed with each other, the rotation of the adjustment ring 18 is always restricted. Therefore, even if the adjustment ring 18 is rotated to adjust the height of the print belt 8 and the hand is released from the adjustment ring 18, the rotation of the adjustment ring 18 is restricted and will not rotate arbitrarily. The adjusted height of the print belt 8 does not shift arbitrarily. Further, since the wavy protrusions 29 and 30 are engaged with each other, an appropriate click feeling is transmitted to the user when the adjustment ring 18 is rotated, and the height adjustment of the print belt 8 is adjusted to the pitch of the wavy protrusions 29 and 30. Can be done in stages.
[0021]
The embodiment of the present invention has been described above. In the above-described embodiment, the number of the inclined portions 22 is two. However, the number of the inclined portions 22 is not particularly limited. 22 may be of one C shape as shown in FIG. Since the number of the guide portions 10 that are in sliding contact with the inclined portions 22 may be the same as the number of the inclined portions 22, when there are two inclined portions 22 as in the embodiment described above, the number of guide portions 10 is also two. When the number of the inclined portions 22 is one, the number of the guide portions 10 is also one. When the inclined portion 22 has a single C shape as shown in FIG. 5, the size of the notch H of the inclined portion 22 is the size that the guide portion 10 can be accommodated.
[0022]
Further, in the above-described embodiment, the guide portion 10 has a protruding shape with an arc shape at the upper end. However, the shape of the guide portion 10 is not particularly limited, and for example, the same shape as the inclined portion 22. In this case, by providing the same number of inclined portions 22 on the upper surface of the frame body 4 as to be symmetrical with the inclined portions 22, the guide portions 10 inclined in the circumferential direction may be symmetrical. The height of the print belt 8 can be adjusted by the same method as in the above-described embodiment. Furthermore, in the above-described embodiment, the inclined portion 22 is provided on the lower surface of the adjustment ring 18 and the guide portion 10 is provided on the upper surface of the frame body 4 of the rotary stamp 3. There is no problem even if the inclined portion 22 is provided on the upper surface of the frame body 4. Even in such a case, the height of the print belt 8 can be adjusted by the same method as in the above-described embodiment. Furthermore, in the above-described embodiment, the resilient member 12 is a metal leaf spring. However, the resilient member 12 may be a coil spring or an elastic plastic spring.
[0023]
