On the other hand, it will be described below the operation and operation of the printer equipped with a height-adjustable ink head unit according to the present invention having the above-described configuration.

The printer according to the present invention is for a special job (woodblock printing, lithographic printing, glass printing, etc.) used for printing a printed matter having a certain thickness and volume, rather than being applied to a general purpose printer used for document writing in a general home or office. More preferably applied to the printer.

That is, in the printer according to the present invention, after the to-be-printed object having a predetermined volume and thickness is placed on the conveying means 32 of the upper surface of the fixed frame 30, the printer is moved to the lower end where the ink head unit 20 is installed. The height adjustment of the ink head unit 20 is performed by the elevating means 40 on the upper surface of the to-be-printed object so as to maintain the most suitable interval for printing.

The height adjustment method of the ink head unit 20 of the printer according to the present invention has the advantage that can be used in parallel or automatic and manual and manual.

First, the automatic adjustment operation of the ink head unit 20 of the printer according to the present invention will be described. Automatic adjustment of the ink head unit 20 is performed by an operation unit 26 attached to one side of the fixed frame cover 25 installed on the upper surface of the fixed frame 30 or provided therein.

The user first checks the volume and thickness of the to-be-printed object with the naked eye so that when the to-be-printed object enters the lower portion of the ink head unit 20, the operation unit 26 is provided at a height such that the lower end of the ink head can be maintained at a predetermined distance from the to-be-printed object. After raising the ink head unit 20 to a predetermined height by operating the to-be-printed object on the conveying means 32, it moves to the printing position.

When the user selects and operates the up / down switch provided in the operation unit 26, the lifting drive motor 47 installed in the center of the upper surface of the fixed frame 30 via a control panel (not shown) provided with a signal of the operation switch separately. The lifting drive motor 47 is operated by sending a signal to the motor.

The elevating drive shaft 46 coupled with the elevating drive motor 47 rotates by the rotation of the elevating drive motor 47, and the power conversion units provided at both ends of the elevating drive shaft 46 by the rotation of the elevating drive shaft 46. The worm 51 and the worm wheel 52 of 50 are rotated, and both vertical rotation shafts 42 having the outer circumference coupled to the inside of the worm wheel 52 are rotated at the same time by the rotation of the worm wheel 52.

The vertical lifting body 44 coupled to the helical gear formed on the outer circumference of the vertical rotation shaft 42 by the rotation of both vertical rotation shaft 42 is engaged with the inside of the vertical lifting body 44 while the operation of raising or lowering Lifting operation is also performed at the same time, the flange 45, the lifting operation of the flange 45 is accompanied by the ink head unit 20, the lifting operation is performed.

Since the same head is formed on the outer circumference so that the vertical movement shaft 42 of both sides has the same gear pitch and the same rotation direction, the vertical lifting body 44 coupled to the ink head unit 20 that is lifted and operated has the same rotation ratio. The vertical lifting body 44 is simultaneously coupled to the auxiliary guide shaft 43 provided at a predetermined interval before and after the vertical rotating shaft 42 to maintain the horizontal state. The lifting operation is performed before and after, while the left and right balance is maintained, the lifting is performed.

As such, since the vertical rotation shaft 46 is rotated by the driving of the elevating driving motor 47, the vertical moving body 44 and the flange 45 on which the ink head unit 20 is installed are lifted and required according to the thickness of the printed object. Since the ink head unit 20 can be freely moved to one height, it is possible to print on the surface of various to-be-printed materials having different volumes and thicknesses.

As such, the height of the surface of the object to be printed and the height of the ink head unit 20 can be automatically adjusted by the driving of the lifting driving motor 47, and the lifting driving shaft is required to precisely adjust the height again. By turning the manual handle 60 provided at the outside of the 46, the surface of the to-be-printed object and the ink head and the gap can be precisely adjusted, thereby reducing unnecessary waste of time required for automatically adjusting the height of the ink head unit 20. It is possible to precisely adjust the distance between the surface of the object to be printed to obtain a clear print.

In particular, when adjusting the height of the ink head unit 20, the observation hole 12 of a predetermined size vertically penetrates the side of the upper cover 10 of the upper end of the manual handle 60, one side of the observation hole 12 The scale display unit 14 is provided on the surface, so that the operator visually observes the scale of the scale display unit 14 and the height of the vertical lifting body 44 through the observation hole 12 with the naked eye. Since it is adjustable, it is easy to adjust the height of the vertical lifting body 44.

In addition, the lift drive motor 47 and the lift drive shaft 46 when the operation of the manual handle 60 is made of a coupling structure that is in a no-load state because of the manual height adjustment of the ink head unit 20 lift drive motor ( 47) does not adversely affect, the manual handle 60 is made of a removable structure can be used to separate or use as needed.

Vertical lifting means 40 of the ink head unit 20 applied to the present invention can be appropriately adjusted according to the volume and thickness of the to-be-printed object, but this is limited by the height of the vertical axis of rotation 42 In consideration of the vertically movable range of the elevating means 40 according to the intended use and the object to be used, it is preferable to select and manufacture a vertical rotation shaft 42 having an appropriate height. It is natural that height can be adjusted.

As described above, the printer equipped with a height-adjustable ink head unit according to the present invention is adjusted to an appropriate height according to the volume and thickness of the substrate to be printed on the surface of all printable substrates such as wood, stone, and glass. Since it is possible to print on the surface of various kinds of to-be-printed materials, it is possible to print products with excellent print quality, which makes it possible to apply printing technology to various industrial fields, and also to automatically or manually operate ink head units. It is possible to adjust the height to reduce the time required for adjusting the height of the ink head unit to have a useful effect to make the print job smoothly.
