Description

 The present invention relates to a printing apparatus, and in particular, has a plurality of rotating arms that can rotate around multiple axes and flexibly move an ejection head of a printing apparatus to an appropriate position, thereby waiting for printing. The present invention relates to a three-dimensional surface printing apparatus that can be printed on a surface of the printer and is applied to a print waiting object having a curved surface, and further, a curved surface.

  Conventional standard printing equipment is usually composed of two independent structures, an operation platform used for fixing a printing apparatus, a processing member platform used for fixing a processing awaiting member (that is, an object awaiting printing), including.

  Among them, the printing apparatus is equipped with an ejection head. The processed member platform is provided with a fixed base and used to hold a property waiting for printing. Thereby, a printing process is performed on the flat surface of a soft article (for example, a sheet or cloth) or a hard article, and a predetermined pattern, character, or line is printed.

  In the printing process, the conventional platform of the workpiece platform is usually fixed and cannot be moved. Therefore, after sandwiching a property awaiting printing, the ejection head of the printing apparatus can only print on the surface outside the property. After completing the printing on the outer surface, it is necessary to manually move the property waiting for printing and print on the remaining surface of the property.

  Therefore, when printing is described, regarding the operation, it is necessary to temporarily stop the printing process and move to a property waiting for printing. This increases the time required for the printing process and increases manpower and time costs. In addition to the increase in cost, for a property waiting for printing that does not have a flat surface, it is difficult to achieve the printing of the three-dimensional surface of the property because the property is moved.

  Further, in the control method of the ejection head of the printing apparatus, the conventional technology already has a technique for performing control using an apparatus, but usually controls the ejection head to be linearly displaced along at least two axes. Since this is only possible, the operation control of the ejection head is extremely limited, and sufficient flexibility cannot be obtained in the operation control direction.

In view of this, in order to improve the deficiencies of conventional standard printing devices, the inventors of the present invention present a three-dimensional surface printing device, which can rotate around multiple axes and perform multiple rotations. It has an arm, and the ejection head of the printing apparatus can be flexibly moved to an appropriate position so that printing can be performed on the surface of an object waiting to be printed.
Conventionally, as a three-dimensional object surface printing machine capable of printing predetermined characters and the like on a three-dimensional object whose surface is curved or rugged, there is one disclosed in Patent Document 1, for example.
