DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing device for writing characters on a stupa.

[0002]

2. Description of the Related Art As shown in FIG. 1A, a stupa writes a deceased name on the surface 1a of a stupa 1, while FIG.
As shown in the figure, it is common to write the name and date of the person to be memorialized on the back surface 1b. In the past, writing of characters for this stupa was all done manually by a person using a brush or the like.

[0003] Writing characters on a stupa with a brush is a very time-consuming task, and the fact that the number of people who are good at writing is decreasing in recent years has made it extremely difficult to secure writers. It has become to. In addition, if the character is miswritten, there is the trouble of grinding and rewriting the surface of the stupa, and if rewriting a new stupa, the misplaced stupa is wasted.

[0004] Then, the present inventors have previously described Japanese Patent Application Laid-Open No. Hei 9-1868.
In the publication, a reference roller is provided in contact with a printing surface having a predetermined interval from a printing nozzle of a dot inkjet printer from above, and a pressing roller which is constantly pushed up by a spring force is provided below the reference roller in a vertically movable manner. By rotating a part of the roller as a driving roller by the motor of the printer,
A stapler printing device that sends a stapler inserted between a reference roller and a pressing roller was proposed. With this device,
For the first time, it was possible to automate the writing of characters into the stupa.

[0005]

The above-described apparatus is of a type in which a stapler is sent between a reference roller and a pressing roller. Since the stapler is sent based on frictional resistance between each roller and the stapler, the stapler is sent. A slipping phenomenon often occurs, and there is a disadvantage that the printing timing is shifted and the character style and character spacing are lost. In particular, since the stupa is made of a thin wooden plate, warpage easily occurs depending on the weather and storage conditions, and this has caused a slip.

[0006] There are many types of stupa, and their lengths (heights), widths, and thicknesses are different. To write characters at individual predetermined positions according to the type of stupa, it is necessary to use a stapler for a printer. Although it is necessary to reliably perform the positioning, there is also a problem in that it is difficult to position the stupa with the above-described device.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a printing apparatus for a stupa that can reliably and easily send and position the stapler to a printer.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a printing device according to the present invention will be described in detail with reference to the drawings. As shown in FIG. 2, this printing apparatus has a jig 2 to which a stupa 1 is fixed, attached to a conveyor 3, and a dot inkjet printer 4 installed toward a conveying path of the conveyor 3. Reference numeral 4a denotes an ink box that supplies ink to the dot inkjet printer 4.

That is, the conveyor 3 is a roller-type conveyor in the illustrated example, and a lower roller 3a and a side roller 3b provided on both sides of the conveying path respectively connect the base 2a of the jig 2 extending along the conveying path. By supporting and guiding, the jig 2 is reciprocally mounted on the conveyor path of the conveyor 3.

Further, as shown in FIG. 3 showing the plane of the conveyor 3 and FIG. 4 showing the side surface of the conveyor 3, respectively, the base 2a of the jig 2 extends between the wheels 5a and 5b under the conveyor path of the conveyor 3. It is fixed to the belt 6 by means such as bolting, and the wheel 5a is
The jig 2 is reciprocated on the conveyance path of the conveyor 3 by driving the timing belt 6 by rotating the jig 2.

On the other hand, the dot ink jet printer 4
In the illustrated example, the printer head is installed at a substantially central portion of the conveying path of the conveyor 3 toward the conveying path, and performs printing in synchronization with the moving speed of the staircase 1 moving through the jig 2. In order to synchronize the printing speed with the moving speed of the staircase 1, for example, the pulse encoder 7 may be controlled to synchronize the rotation of the motor 5c for driving the timing belt 6 with the printing speed.

Here, when printing on the stupa 1,
The stupa 1 must be securely fixed to the jig 2.
Therefore, as shown in FIG. 5, the jig 2 has a pair of blocks 8a and 8b for sandwiching the stupa 1 from one end and the other end thereof in the longitudinal direction, and the jig 2 is inserted into the both sides of the stupa 1 shallowly to position the stupa 1. A plurality of pins 9a and 9
It is important to set b.

That is, since the jig 2 has a length that can accommodate all the stupa, one of the blocks 8a and 8b, for example, the block 8b is connected to the stupa 1 according to the length of the stupa 1 placed thereon. It is necessary to fix the upper end and the lower end of the staircase 1 with the blocks 8a and 8b by movably installing the block 8b according to the length of the staircase 1. The blocks 8a and 8b are formed in a V-shape that opens toward the stupa 1 according to the general shape of the upper end and the lower end of the stupa 1, and the upper and lower ends of the stupa 1 are located at the center in the width direction of the stupa 1. It was made to grasp securely. Therefore, the stupa 1 can be fixed to the jig 2 based on the center of the width thereof, so that the position of the stapler 1 with respect to the printer 4 can be reliably determined.

The block 8b is constructed so as to be able to advance and retreat slightly with respect to the block 8a because the length of the block 1 varies and the block 1 must be pressed against the block 8a. That is, as shown in FIG. 7, the flange guide pin 11 is passed through the guide holes 10 provided on both sides of the block 8b, and the tip of the guide pin 11 is inserted and fixed to the fixed block 13 with the intervention of the spring 12, The block 8b is attached to the fixed block 13 so as to be able to advance and retreat.
Further, the bolts 14a movably mounted in the T-grooves on the upper surfaces of the side plates 2b and 2c shown in FIG. 7 are passed through the fixing block 13, and the bolts 14a protruding from the fixing block 13 are tightened by the nuts 14b to fix the bolts 14a. The block 13 was movably fixed to the side plates 2b and 2c of the jig 2.

Further, when fixing the stupa 1 to the jig 2,
As shown in FIG. 5, a plurality of pins 9a and 9b are pierced at substantially equal intervals on both sides of the stupa 1,
It is advantageous to apply a restraining force from both sides of the to prevent the warp of the stupa 1 in particular. In order to move the pins 9a and 9b back and forth (pierce) with respect to the side surface of the stupa 1, FIG.
As shown in FIG. 7, the distal end of the guide shaft 16 is inserted into the bearing 15 attached to the side plate 2b under the intervention of the spring 17, and the arm 1 having a pin 9a at the distal end is provided at the base end of the guide shaft 16.
8. Then, attach the knob 19, and push and pull the knob 19 and rotate it. That is, by operating the knob 19,
When the arm 18 is turned upward, the stopper 20 restricting the axial movement of the guide shaft 16 comes off the groove 16a, the guide shaft 16 moves by the action of the spring 17, and the pin 9a moves to the side of the staircase 1. As a result, the pin 9a can be stabbed into the side surface of the stupa 1. At this time, it is preferable that the pin 9a is securely inserted into the side surface of the stupa 1 by pushing the knob 19 by hand. On the other hand, to remove the pin 9a from the stupa 1, pull the knob 19 to remove the pin 9a from the stupa 1,
The guide shaft 16 may be rotated by 90 degrees as it is, and the stopper 20 may be fitted to the groove 16a of the guide shaft 16 and the guide shaft 16 may be fixed. The above configuration is the same for the pin 9b side.

Also, adopting a piezo-electric method for the dot ink jet printer 4 for printing on the staircase 1 is advantageous for improving the printing efficiency. That is, the piezo-electric type printer prints in a non-contact manner by jetting ink droplets onto a printing surface from a large number of nozzles finely processed on the entire surface of the print head. For example, if the print head is 128 dots and 128
Equipped with channel nozzles, applying electric pulse signals, and ejecting ink by vibration of each channel wall surface,
The form fits advantageously. In addition, the drop-on-demand method is recommended for the ink supply system, which can eject the required amount of ink when needed and does not require the circulation of solvent. Is done.

Next, the above-described printing apparatus is of a type in which the stupa 1 is placed horizontally on the jig 2 and fixed, and printing is performed on each side of the stupa 1. As shown in FIG. It is also possible to fix the stupa 1 to the jig 2 in such an arrangement that the width direction of the stapler 1 is perpendicular to the base 2a of the base 2a, and to simultaneously perform printing by the printer 4 from the front and back surfaces of the stapler 1. At this time, the blocks 8a and 8b and the pins 9a and 9b for fixing the stupa 1 to the jig 2 may be moved to a position corresponding to the upright posture of the stupa 1. Same as in the case.

In order to perform printing on the stupa 1 using the printing apparatus of the present invention, for example, a computer is attached to the printing apparatus, and the length and width of the stapler 1 are first input to this computer, and the stapler 1 is input. Enter the name of the deceased to be printed on the front side of the device 1 using an input device such as a keyboard or a scanner. Similarly, the name and date of the memorial service to be printed on the back of the stupa 1 are input in the same manner.

When the above input is completed, as shown in FIG. 5, the stupa 1 is fixed to the jig 2 via the blocks 8a and 8b and the pins 9a and 9b, and the conveyor 3 is operated. And the jig 2 are transported to the printer 4 side. Next, the printer 4 is operated, and printing is performed by synchronizing the printing speed with the transport speed of the stupa 1 by the pulse encoder 7. At this time, the printer head sprays ink from the nozzle while
Print in the width direction of. When the printer head reciprocates once and stops, the motor 5c for driving the timing belt 6 starts to move the jig 2, and the printer head restarts here. By repeating this, printing of the stored characters is completed. Thereafter, the jig 2 is returned to the starting position again, the staircase 1 is removed from the jig 2, turned over, fixed to the jig 2 again, and printing on the back side of the staircase 1 is performed in the same manner.

Here, the reciprocating movement of the jig 2 corresponds to the photoelectric switch 21a for detecting the limit of the jig 2 when the jig 2 moves forward as shown in FIG.
The limit is set by the photoelectric switch 21b for detecting the limit when the jig 2 moves backward. As described above, the apparatus shown in FIG. 8 may be used to simultaneously print on the front and back surfaces of the stupa 1.

[0026]

According to the apparatus of the present invention, the stupa is fixed to the jig, and the jig is transported to the printer so that the stapler can be reliably sent to the printer. Character groups can be printed accurately. In addition, since the stupa is securely fixed to the jig via the block and the pin and does not shift in position, if this jig is moved on the transport path, the position of the stupa with respect to the printer will be automatically determined. ,
More accurate printing can be performed.
