Abstract

PURPOSE:To make the execution of a sure setting operation possible without the peeling off or blurring of a print on and after the subsequent process, by making the supply of the resin film sheet which thermally transfers the print on the surface of a tire structure material via a marking press to the clearance between the thermal transfer type marking press capable of freely going up and down and a type support possible. CONSTITUTION:A printing apparatus 1 has the thermal transfer type marking press 4 capable of freely going up and down via a lifter 3 on a type support 2. A resin film sheet 5 is thermally transferred strongly onto the side wall part of a tire structure material W with the type of a marking press 4. This resin film sheet 5 is horizontally supplied between the marking press 4 and the type support 2 with the film feed roll 14 and the film winding roll 16 rotationally driven via a drive motor 15 which are arranged on both sides of the marking press 4. The said sheet 5 is pulled downward at each pitch by the going up and down of the marking press 4 and sent out. At the same time, the printing apparatus is so constructed as to wind the said sheet 5 on the other side.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a printing device for tire constituent materials in a tire molding process, and more specifically, it relates to a printing device for printing tire constituent materials in a tire molding process, and more specifically, it relates to a printing device for printing tire constituent materials in a tire molding process, and more specifically, for coloring the surface of a green tire using a resin film sheet. The present invention relates to a printing device for tire constituent materials that thermally transfers printed characters.

[Prior art]

Conventionally, in the tire manufacturing process, when specifying the tire serial number, manufacturing date, manufacturer, etc. on the green tire,
After the tire is formed, a worker affixes an unvulcanized label with the necessary information printed on it to the surface of the tire (mainly near the bead side of the tire sidewall).
In addition, stamp transfer was performed using quick-drying ink.

However, since such work was performed manually by an operator for each manufactured tire, there was a problem in that work efficiency was extremely low.

In addition, depending on the method used to attach the label, it often peels off during the subsequent manufacturing process such as the vulcanization process or finishing process, and when using the ink stamp method, there is a problem that the label gets dirty and the markings become unclear.

[Purpose of the invention]

This invention was devised by focusing on such conventional problems, and its purpose is to save manual labor by automatically using a mechanical device during the tire molding process. It is possible to improve work efficiency, and since the printing is reliably printed on the molded tire, there is no possibility that the printing will peel off after the next process.
To provide a printing device for tire constituent materials that can always perform printing work reliably without becoming unclear.

[Structure of the invention]

In order to achieve the above-mentioned object, this invention installs a thermal transfer type stamping device that can be raised and lowered freely via a lifting device on a printing support stand provided in the middle of a material supply device, and the marking device and the printing support stand are connected together. The gist of the present invention is that a resin film sheet is interposed on the surface of the tire constituent material so as to be capable of being supplied with a resin film sheet that thermally transfers the print via the marking device.

[Embodiments of the invention]

The present invention will be described in detail below based on the accompanying drawings.

FIG. 1 is a plan view of a printing device 1 provided in the middle of a material supply device (not shown) for tire constituent material W (side tread in this embodiment), FIG. 2 is a front view thereof, and FIG. The printing device 1 is equipped with a thermal transfer stamping device 4 that can be raised and lowered freely via a lifting device 3 on a printing support 2, and the marking device 4 and the printing support 2 are connected to each other. In between, a resin film sheet 5 is interposed so as to be horizontally feedable, and the resin film sheet 5 thermally transfers a colored print onto the surface of the tire constituent material W via the marking device 4.

In the marking device 4, a type 8 is removably attached to the lower part of a holder 6 via a bolt 7 or the like, and the type 8 is always heated to a constant temperature via a heater 9.

Further, the holder 6 is connected to the lifting device 3, that is, the frame 10.
The holder 6 is suspended from the upper part of the holder 6 in a state where it is always urged upward via a leaf spring 11. Furthermore, a crimping cylinder 12 is provided on the side of the holder 6, and the holder 6 is supported by the crimping cylinder 12 so as to be movable up and down.

Further, on both sides of the printing support stand 2 located below the typeface 8, there are guide rollers 13a for guiding the tire constituent material W.
, 13b are provided, and the supplied tire constituent material W
The system is configured to supply the following process at a constant rate.

Further, the resin film sheet 5 is a protective film,
It is composed of a multilayer combination of a colored layer, a thermosetting adhesive layer, etc., and is firmly thermally transferred onto the sidewall portion of the tire constituent material W using the printing characters of the marking device 4.

This resin film sheet 5 is placed between the marking device 4 and the printing support base 2 by a film supply roll 14 arranged on both sides of the marking device 4 and a film take-up roll 16 which is rotationally driven via a drive motor 15. is supplied horizontally, and is pulled downward every pitch by the raising and lowering of the marking device 4 to be sent out, while being wound up on the other hand.

With the above configuration, it is possible to thermally transfer the marking onto the sidewall portion of the tire constituent material W using the marking device 4 via the resin film sheet 5, thereby eliminating the need for manual work as in the past. In addition, the clearly marked part will not become unclear or peel off after being engraved.

〔Effect of the invention〕

As described above, this invention includes a thermal transfer stamping device that can be raised and lowered freely via a lifting device on a printing support provided in the middle of a material supply device, and a space between the marking device and the printing support. In addition, a resin film sheet that can be supplied to the surface of the tire constituent material to thermally transfer the print via the marking device is installed, making it possible to save the manual labor required in the past and improve work efficiency. Moreover, since the characters are reliably printed on the molded tire, the characters do not peel off or become unclear after the next process, and the printing work can always be performed reliably.
