Description

[0001] The present invention relates to a transfer printing device equipped with alignment means,

The present invention relates to an apparatus for printing a specific pattern, a pattern, a symbol, and the like on a glass panel by a transfer printing method, so that alignment of a transfer film (fabric) and a glass panel can be set more quickly and accurately.

Generally, designs made of plastic or metal, stationery products made of glass panel and rubber, and other various shapes or letters printed on the outer surface of the household goods are mainly made by the transfer printing method.

In such a transfer printing method, a transfer film (hereinafter, referred to as a transfer sheet) on which a specific pattern and a photograph is placed is placed on a target article placed on a table, and a transfer sheet is pressed with a heating roller at a proper temperature When the object and the transfer sheet are moved in one direction in a state in which they are pressed tightly, a pattern or a photograph of the transfer sheet is transferred to the object article by the heat of the heating roller and printed.

In order to accomplish this, most of the conventional general transfer printing apparatus configuration is provided with a table on which a target article is placed, which is mounted on a table by a driving motor so as to move left and right along a rail, and on such a table there is mounted a transfer sheet And a heating roller mounted on the carrier are lifted and lowered together by a cylinder.

In such a conventional transfer printing apparatus, when a transfer sheet placed on an upper side is first lowered and placed on a target article while a target article is mounted on a table, the heating roller presses the transfer sheet to adhere to the target article, When the carriage is moved to one side along the rail, the heating roller is idled by the frictional force, and the transfer sheet is pressed against a passing article to be transferred, so that transfer printing is performed.

As the carrier of the heating roller and the transfer sheet mounting table of the transfer sheet are raised, the transfer sheet and the heating roller are moved upward, and the table is moved backward to the original position Is returned.

However, in the transfer printing apparatus described above, since the operator simply waits while the loading table is returned, there is a problem that the operation time is long due to the loss of operation. In addition, since the above-described transfer printing apparatus is a system in which the heating roller is idly rotated by a frictional force in a state where the heating roller is fixed at one position, and the object article and the transfer sheet are transferred while being moved together, a pattern flowed on the transfer sheet is accurately transferred If the number of defective products increases, all of the defective products cause a rise in cost, resulting in a rise in product prices, which causes a problem of poor price competitiveness. In order to solve the problems of the conventional transfer printing apparatus, the transfer sheet is mounted on the table on the table by the transfer sheet mounting table on both sides of which the transfer sheet roll is mounted so that the object and the transfer sheet on the table are stopped, A method and an apparatus for performing a printing operation while the heating roller itself is rotated and moved by pressing down a transfer sheet has been developed by the present applicant and registered as Patent No. 294155 in 2001. [ That is, the above-described invention can be applied to a case where the transfer sheet mounting table 35 is moved up and down by the air cylinder 42 in a state that the transfer sheet mounting table 35 is engaged with the support tube 34a fitted to the support rod 32 at the lower end of the table 33 And the roll transfer sheet 52 sandwiched between the roll fixing shafts 35a and 35b at both ends of the transfer sheet mounting table 35 is moved in the direction from the one side roll fixing shaft 35a to the target article 51 To the other-side roll-fixing shaft 35b, and is then intermittently repetitively rotated and stopped. While the transfer sheet 52 is advanced by a predetermined length between the object article 51 and the heating roller 38 and is wound and stopped, the transfer sheet mounting table 35 is lowered to transfer the transfer sheet 52 to the object 51 and then the heating roller 38 mounted on the upper roller carrier 37 is lowered by the air cylinder 49 so that the transfer sheet 52 is pressed against the object 51 by pressure transfer . This selection name is a method in which the carrier operating portion 48 is moved along the rail base 39 by the piston shaft 41a of the air cylinder 41 connected to one side so that the heating roller 38 of the roller carrier 37 naturally It is moved while rotating.

When the transfer sheet 52 and the target article 51 are in the stopped state and only the heating roller 38 is rotated, the pattern of the transfer sheet 52 is transferred to the target article 51 cleanly, The quality improvement as well as the defect incidence rate can be considerably reduced, and the cost reduction due to this can be considerable.

Then, after the transfer printing operation, the heating roller and the transfer sheet are returned, and the mounting table on the table remains in the correct position, so that the loading of the finished product and the mounting operation of the new object for the next job can be immediately performed. It is possible to eliminate the problem that the worker can not wait for the work while waiting for the work, thereby improving the productivity by shortening the work time. However, since the selection name is a state in which both sides of the loading table are covered by the transfer sheets of both transfer rolls, the article to be transferred is printed through the front surface of the table by using the transfer sheet upward when the transfer sheet is lifted along the transfer sheet mounting table The completed workbench must be removed and the workbench loaded with the new object should be mounted. Therefore, the above-mentioned selection name means that all of the objects are moved in / out from the front of the table,

It is difficult to configure the printing apparatus to be carried out by a continuous operation by an automatic line, and since the worker takes out the loading and unloading work of the mounting table like the conventional transfer printing apparatus, the labor and the cost reduction can not be achieved .

The problems to be solved by the present invention are as follows.

First, it is an object of the present invention to provide an apparatus for performing transfer printing using a roller provided with a heat generating means.

It is another object of the present invention to provide a device capable of effectively performing alignment (alignment of a fixed position) of a transfer film (fabric) and a glass panel.

Third, it is another object of the present invention to enable precise and effective transfer printing by moving a stage on which a glass panel is mounted to front, rear, left, right and up and down.

Technical features of the present invention are as follows.

An upper structure equipped with a camera for confirming the alignment of the transfer film and the glass panel; A roller support portion provided with a roller; A base body installed at a lower portion of the upper structure; A stage unit installed at the center of the base body and having a glass panel mounted thereon; A transfer film mounting part provided along the rim of the base body part; A descent force controlling unit for controlling ascending and descending of the stage unit; A horizontal movement control unit for controlling the horizontal movement of the stage unit in the front, rear, left, and right directions; A roller heating wire disposed inside the roller; A stage hot wire portion provided on the stage portion; A glass panel receiving part provided at the center of the stage part and having the same shape as the outer shape of the glass panel to receive the glass panel; And an alignment control unit for comparing the sensed image of the camera provided in the upper structure with the reference image to check alignment and calculating the degree of discrepancy when they do not match, to the horizontal movement control unit.

Technical effects of the configuration of the present invention are as follows.

First, transfer printing may be performed using a roller provided with a heat generating means.

Second, the alignment between the transfer film (fabric) and the glass panel (alignment of the film) can be effectively performed.

Third, precise and effective transfer printing is possible by moving the stage on which the glass panel is mounted to front, back, left, right and up and down.
