In addition, the rotational force of the driving roller can be stably transmitted to the feed plate during the horizontal transfer of the flat plate feed plate exhibits the advantage that the slip phenomenon does not occur.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a schematic configuration of a flatbed printer according to an embodiment of the present invention will be described.

The printer of this embodiment includes a transfer plate 20 in the form of a flat plate on which a to-be-printed object is largely seated, a printer body 10 for transferring the transfer plate 20 back and forth in the horizontal direction, and an upper portion of the printer body 10. The head portion 30 is detachably coupled, and the cartridge 40 is transferred from the head portion 30 to the left and right directions and prints the to-be-printed object.

Looking in more detail of the configuration of the printer body 10, the drive roller 11 and the pressure roller 12 is formed in pairs on both sides as shown in Figure 4 in order to transfer the transfer plate 20 back and forth, The roller 12 is the coil spring (12a) is wound on the support shaft to always press the conveying plate 20 while the downward elastic pressing force is applied, the drive roller 11 to the roller drive motor 19 from one side Since it is rotated by receiving the rotational force through the drive shaft (19 ') is made to contact the bottom surface of the transfer plate 20 is configured to transmit the transfer force.

Particularly, in the present invention, the driving roller 11 has a friction processing part 11a formed with a hobbing process in order to enhance friction with the bottom surface of the transfer plate 20, and is formed at both ends corresponding to the pressure roller 12.

In addition, the transfer plate 20 is formed with a cutout portion 21 so as to correspond to the friction processing portion (11a) so that both sides of the direct contact is transmitted more stable transfer force.

That is, as shown in Fig. 5, the outer portion of the cutout portion 21 is formed with a separate portion 21 'having a constant width d, so that the portion is pressurized by the driving roller 11 and the pressure roller 12. When the force is applied to the conveying plate 20, unlike the central portion of the main body, the separate portions 21 'on both sides have individual fluidity, so as to be affected by the pressing force by the pressure roller 12 as shown in FIG. As it descends further to (h), it can receive high feed force.

On the other hand, it is preferable to form a urethane coating layer 22 in a thin film on the bottom portion of the transfer plate 20 corresponding to the friction processing portion 11a of the drive roller 11 to further increase the frictional force. That is, through the urethane coating layer 22 having a predetermined elastic force it is possible to further maximize the friction force with the friction processing portion (11a).

And, on both sides of the printer main body 10, a support rod 13 for lifting up and down the head portion 30 is configured, and the lifting support 14 is coupled to both support rods 13 so as to be liftable, among which One lifting base 14 is equipped with a lifting shaft 15 for transmitting the lifting feed force. That is, since the lifting shaft 15 has a spiral structure and is screwed with the lifting support 14, the lifting support 14 is driven up and down in the forward rotation, and the lifting support 14 is lowered in the reverse rotation. To be driven.

The lifting shaft 15 is pivotally supported by the bearing 9, the upper end and the lower end, the bevel gear 17 is configured to receive the rotational force from the rotation rod 16 at the bottom, One end of the rod 16 has a lift adjusting handle 18.

Reference numeral 5 is a transfer plate detection unit for detecting the forward and backward transfer position of the transfer plate 20, 6 is a guide roller for guiding the transfer operation of the transfer plate 20 from both sides, 7 is to store the waste ink A motor for transferring to the container, and 8 represents the waste ink storage container receiving groove, respectively.

On the other hand, in the lower portion of both sides of the head portion 30 in the present invention, the detachable frame 31 is fixedly installed to facilitate the coupling and separation operation with the elevating support 14.

That is, as shown in FIG. 2A, the guide groove 32 and the fastening hole 33 having a predetermined length in a vertical direction on the side of the detachable frame 31 are formed in a plurality of places, and the lifting base 14 corresponding thereto. Guide protrusions 14a and fastening holes 14b are formed on the side, respectively, so that the fastening pins 34 are coupled to both fastening holes 14b and 33 after the guide protrusions 14a are fitted into the guide grooves 32. It was.

And, as an application example to form a guide shape of the "b" form by extending the horizontal portion 32 'on the top of the guide groove 32 as shown in Figure 2b, due to the structure of the horizontal portion 32' guide projections ( 14a) it is desirable to achieve a more stable bonding state with each other.

And, the head portion 30 is configured with a connector 35, and receives a control signal for printing, one side transmits a driving force to a conveying belt (not shown) for conveying the cartridge 40 in the left and right directions It can be seen through Figure 1 that the cartridge transfer motor 41 is configured.

The effects of using the flatbed printer of the present invention constituting such a configuration will be described.

First, in the state where the to-be-printed object is placed on the transfer plate 20 or fixed to the upper surface of the transfer plate 20 by using a separate jig (not shown), the operator uses the lifting control handle 18 to raise the head 30. Adjust the height of the lift.

Subsequently, when the driving signal is applied, the transfer plate 20 is horizontally moved in the front-rear direction by the driving of the roller driving motor 19, and the head portion 30 is driven by the cartridge feeding motor 41. As the mounted cartridge 40 is moved left and right, the printing operation for the printed matter is performed.

In particular, since both ends of the driving roller 11 in the present invention, which transfers the front and rear conveying force to the conveying plate 20, the frictional processing portion 11a is formed by the hobbing processing in the form of unevenness. The frictional force with the urethane coating layer 22 is maximized with this, and thus it can be seen that a more stable transfer operation can be achieved without slip phenomenon between each other.

In addition, due to the structure of the cutouts 21 on both sides of the transfer plate 20, the pressing force and the transfer force by the driving roller 11 and the pressure roller 12 are more stably transmitted.

On the other hand, when a failure occurs in the printer during such a use process, the head unit 30 is separated from the printer main body 10 to check the device.

That is, in this case, when the fastening pins 34 fastened to the fastening holes 14b and 33 formed in the detachable frame 31 and the lift support 14 are removed, the detachable frame 31 is simply the lift support 14. ) Is supported by the guide protrusion (14a) that is formed to protrude, so that when the operator lifts the head portion 30 in such a state is immediately separated from the printer body (10).

Therefore, the repair work on the printer body 10 can be easily performed in the state in which the head part 30 is separated.

On the other hand, when the repair work is completed, the head unit 30 is reassembled to the printer body 10. In this case, the detachable frames 31 on both sides of the head unit 30 are seated on the lifting base 14, respectively. When the guide groove (14a) is guided to the guide groove (32) is made to be mutually coupled to be made, it can be seen that a stable fastening operation using the fastening pin 34 in this state.

7 shows a detachable structure between a detachable frame 31 and a lift base 14 according to another embodiment of the present invention.

That is, as shown in the removable frame 31, the fastening holes 33 are formed in two places, the fastening bolts 14a are respectively protruded on the upper surface of the lifting support 14 corresponding to the fastening nut 14c It shows a configuration that can be fastened by a).

Through the structure of the detachable means, it can be seen that the work of disassembling the head part 20 from the printer main body 10 when the printer failure occurs, as well as the work of re-fastening after repair completion can be made more easily.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the flatbed printer structure of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, some embodiments specified as detachable means of the head portion 20 have been described and illustrated, but the shape of the lifting base 14 and the detachable frame 31 may be designed in other shapes as necessary. It can also be.
