Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for determining the transfer position of a transfer paper relative to a curved body when transferring designs, marks, etc. to a curved body such as a helmet.

(Prior Art) Conventionally, it has been common practice to draw an outline indicating the transfer position on the outer surface of a curved body such as a helmet using a paper pattern, and to position the transfer paper based on this outline.

(Problems to be Solved by the Invention) However, drawing an outline by applying a pattern to a curved surface is complicated and takes a long time, which not only leads to inefficiency but also lacks accuracy. It was hot.

Therefore, the present invention aims to solve the problems of the above-mentioned conventional example.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a support that can set the curved body in a correct posture by providing a support portion at the upper end that comes into contact with the circumferential surface of the curved body. , using a transfer paper on which a plurality of positioning marks are printed and a plurality of positioning light beams set so that the projection points are in a three-dimensional positional relationship at each position corresponding to the mark, the curved surface is placed on a support. The present invention is characterized in that, after the transfer paper is set in a correct posture position, the transfer position of the transfer paper relative to the curved surface body is set at a position where each of the marks coincides with each of the light beams.

(Function) The present invention makes it possible to perform positioning by projecting a beam of light onto a plurality of marks printed on transfer paper by using a support provided with a support portion at its upper end that contacts the inner peripheral surface of a curved surface. The curved surface body can be set in the correct posture and position, and at the same time, the projection point of the positioning light beam can be three-dimensionally determined on the curved surface of the curved surface body. After setting, by aligning the projection point of the light beam with the mark on the transfer paper, the transfer position of the transfer paper can be determined much faster than in the conventional method, improving the efficiency of the transfer work. It is possible to perform accurate transcription work without requiring any skill.

(Example) A detailed description will be given below based on an example shown in the drawings. The illustrated embodiment relates to the case where characters 6 are transferred onto a helmet (curved body) 1.

The supporter 2 shown in Fig. 1 is a hemisphere that fixes the base frame 7 on the workbench 8 and faces 10, 10, which faces the upper end of the column 9 on the upper end of the column 9.
A helmet support portion 20 is formed of 0. Positioning protrusions 11, 11 are provided on a pair of hemispheres 10, 10 located on the left and right sides of the four hemispheres 10, 10 facing to the sides, respectively. The helmet support portion 20 is formed so as to be in contact with the inner circumferential surface 14 of the helmet 1 so that the helmet 1 can be positioned. There are three light sources 1 around the support 2.
2, 12, 12 are arranged three-dimensionally, and these light sources 1
2, 12, 12 project positioning light beams 5, 5, 5 which are narrowly converged and travel straight. It is preferable that the light source 12 is configured to project the light beam 5 in a desired direction using a universal joint.

FIG. 2 shows the helmet 1, in which small holes 13, 13 corresponding to the positioning protrusions 11, 11 are provided in the left and right lower portions of the ear flaps. The helmet 1 is thus mounted on the support 2 as shown in FIG.
By fitting into the helmet support portion 20 of the helmet and projecting the protrusions 11, 11 into the small holes 13, 13, the correct posture can be set.

FIG. 3 shows the transfer paper 4, and on the upper surface of the mount 15 three positioning marks 3, 3, 3 are printed. A transfer layer portion 16 is formed on the lower surface of the mount 15, and this transfer layer portion 16 contains a printing ink layer representing the characters 6. The transfer layer section 16 has conventionally been constructed using various ideas, and any of them may be adopted. In the case of the present invention, it is preferable to use a transfer paper 4 suitable for low-temperature printing. still,
It is preferable that the mount 15 is transparent or translucent.

The positioning light beams 5, 5, 5 are set at correct positions, as shown in FIG. 4, and serve as indicators of the transfer position of the transfer paper 4. The worker receives the light beam 5,
Each of the marks 3, 3, 3 on the transfer paper 4 is made to three-dimensionally coincide with each of the projection points 5a, 5a, 5a arranged in a three-dimensional positional relationship on the helmet 1 of 5, 5, The transfer position of the transfer paper 4 relative to the helmet 1 can be determined. After that, a predetermined transfer operation may be performed.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, the number of positioning marks 3 on the transfer paper 4 may be two or four or more, and a number of positioning light beams 5 corresponding to this number may be provided. Further, the positioning marks 3 can also be printed on the lower surface of the transparent or translucent mount 4 of the transfer paper 4. Furthermore, a mark for confirming the support position (one or more places may be placed) is placed on the surface of the curved body 1 such as a helmet, so that when the curved body 1 is set on the support body 2, it is set in the correct posture position. It may be possible to determine whether or not the luminous flux 5 and the confirmation mark match.

(Effects of the Invention) Since the present invention has the above-mentioned configuration and operation, it is possible to quickly determine the transfer position of the transfer paper, improve the efficiency of transfer work, and transfer onto a curved object, which requires skill. Therefore, it is possible to provide a method for determining the transfer position that can be performed accurately without any trouble.
