Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hot stamper for printing a pattern by thermal transfer.

[0002]

2. Description of the Related Art Generally, a hot stamp has a heating head and a roll-type transfer film which is placed close to the heating head, and the transfer film is sandwiched between the surface to be stamped and the heating head. By passing an electric current through the heating head, the metal foil of the transfer film is transferred onto the surface to be stamped.

At this time, for example, when a hot stamp is applied to a paper box, it is necessary to unfold the box to make it flat and place the box on a solid base in order to ensure transfer. ..

[0004]

However, in the above-mentioned conventional one, there is no problem when printing on a box or a flat surface in an unfolded state, but it is used in a small lot, or used as a gift or an advertisement. When a hot stamp is applied to a product, it is often performed on a ready-made product in which the contents are pre-installed in a box.

In this case, if the surface of the box is stamped as it is, the contents are destroyed, and since the surface of the box cannot be supported from the inside, unevenness occurs in the stamp. Therefore, in the conventional hot stamper, The contents must be removed from the box, and the box must be redeployed and flattened before being transferred, which is extremely inefficient.

The present invention has been made in view of the above-mentioned matters, and provides a hot stamper capable of efficiently hot stamping a cylindrical box body in which contents are previously housed. Is a technical issue.

[0007]

In order to solve the above technical problems, the present invention has the following constitution. That is, it is a hot stamper that prints a pattern by thermal transfer on a cylindrical box body in which the contents are previously mounted, and has a conveyor for transferring the box body, and the side of the conveyor has the box body inside. A core to be inserted into and removed from the box to allow the contents to be pushed out of the box, and at a position facing the core, the contents pushed out from the box to be reattached to the box. A technical means is to provide a pressing device and a thermal transfer device above the conveyor at the forward position of the core.

[0008]

In the tubular box, contents, for example, soap are contained, and the contents can be slid by pushing from the side and pushed out.

The box containing the contents is conveyed by a conveyor, and when it reaches the position of a core provided on the side of the conveyor, the core advances toward the conveyor and presses the contents. At this time, the box body is held so as not to move together with the contents.

The contents are pushed by the core and come out of the box body, but stop at a position where the contents do not come out completely. Here, the inside of the box has been replaced by the core, and in this state, the thermal transfer device descends and the metal foil is transferred to the surface of the box held by the core.

Subsequently, as the core is retracted, a pressing device provided at a position facing the core advances toward the conveyor side to press the contents and reload the contents in the box.
Then, the box stamped with hot stamp is transferred by a conveyor, and the process for the next box is started.
