Description

  The present invention relates to a tire marking device and a tire marking method for marking a surface of a raw cover.

  In the tire manufacturing process, in order to distinguish the type and size of the tire, marking on the surface of the raw cover is generally performed, and various apparatuses and methods for that purpose have been proposed (for example, patents). Literatures 1-4).

  FIG. 2 schematically shows a main part of a conventional tire marking device, and a specific marking method will be described.

  As shown in FIG. 2, the tire marking device includes a lifting cylinder 104 that can move a traverse cylinder 102 in a horizontal direction. A plurality of marking pieces 106 (four pieces in FIG. 2) are attached to the tip of the raising / lowering shaft of the raising / lowering cylinder 104. Reference numeral 108 denotes an ink tank. The ink tank 108 stores ink 120, and is configured to replenish the transfer roller 110 that rotates in the direction of the arrow.

  When the elevating cylinder 104 and the marking piece 106 move horizontally in the direction of the arrow and the marking piece 106 contacts the transfer roller 110, the ink is transferred from the transfer roller 110 to the lower surface of the marking piece 106 (FIG. 2A). reference).

  The elevating cylinder 104 and the marking piece 106 are further moved horizontally to the position just above the raw cover T supported by the raw cover support member 112, and then the elevating shaft of the elevating cylinder 104 is lowered so that the lower surface of the marking piece 106 is covered with the low cover T. Press to. Thereby, predetermined marking is given to the surface of raw cover T (refer to Drawing 2 (b)).

  However, in the conventional tire marking device described above, since the upper surface of the ink tank 108 is opened to dispose the transfer roller 110, the ink 120 is scattered and the tire marking device and its surroundings become dirty. Cheap. In addition, since the ink 120 is likely to dry, it is necessary to always replenish the ink tank 108 with a thinning liquid, resulting in an extra cost.

  Therefore, in view of the above, the present invention is a tire marking device that can reduce the occurrence of dirt due to ink around the tire marking device and the device, and can suppress the occurrence of extra costs such as replenishment of a thinning solution. It is another object of the present invention to provide a tire marking method.

The invention described in claim 1
A tire marking device for marking a surface of a raw cover,
A plate having a marking surface with a predetermined mark stamped on the upper surface side;
An ink pot in which ink is sealed and arranged to supply the ink to the marking surface;
A tire marking device comprising: a pad having a transfer surface for transferring the ink supplied to the marking surface and further transferring the transferred ink to a raw cover surface.

The invention described in claim 2
An ink supply step of supplying the ink from an ink pot in which ink is sealed in the marking surface of the plate having a marking surface with a predetermined mark on the upper surface side;
An ink transfer step of transporting the plate supplied with the ink to the marking surface below the transfer surface of a pad and transferring the ink to the transfer surface;
A marking step in which the pad having the ink transferred to the transfer surface is moved to a raw cover surface, the ink is transferred from the transfer surface to the raw cover surface, and marking is performed on the raw cover surface. This is a tire marking method.

  According to the present invention, a tire marking device and a tire marking that can reduce the occurrence of dirt due to ink around the tire marking device and the device, and can suppress the occurrence of extra costs such as replenishment of a thinning solution. A method can be provided.

It is a figure showing typically the principal part of the marking device for tires concerning the present invention. It is a figure which shows typically the principal part of the conventional marking device for tires.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a tire marking device and a tire marking method according to the present invention will be described with reference to the drawings.

1. Configuration of Tire Marking Device FIG. 1 is a diagram schematically showing the main part of a tire marking device according to the present invention. In the tire marking device in the present embodiment, a predetermined mark is imprinted on the upper surface side. A printing plate P1 having a marking surface 10; an ink pot 31 arranged to supply the ink 17 to the marking portion 15 of the marking surface 10 with the ink 17 enclosed therein; and a transfer surface 12 to which the ink 17 is transferred. And a pad 61 having. T is a raw cover.

  Ink 17 is sealed inside the ink pot 31 and the ink supply surface is provided at the lower portion, so that an appropriate amount of ink 17 is supplied to the marking portion 15 so that the ink surface 11 is formed. It has become. A polytank or the like can be used as the ink pot 31, and either solvent-based or water-based ink can be used as the ink 17.

  As described above, since the ink is sealed in the ink pot, the ink does not scatter and the occurrence of contamination around the tire marking device and the device can be reduced. And since it becomes difficult to dry ink by being enclosed in the inside of an ink pot, replenishment of a thinning liquid becomes unnecessary and generation | occurrence | production of an extra cost can be suppressed.

  On the upper surface side of the plate P1, a marking surface 10 having a marking portion 15 on which a predetermined mark is stamped is provided, and an appropriate amount of ink 17 is supplied to the concave portion of the marking portion 15. For this reason, the ink 17 does not protrude around the engraved portion 15, the occurrence of contamination on the plate P <b> 1 is suppressed, and the amount of ink used can be reduced. Examples of the material of the plate P1 include SS400, S45C, and SUS material.

  A transfer surface 12 is provided on the surface of the pad 61 so that the ink 17 supplied to the engraved portion 15 is transferred and the transferred ink 17 is further transferred to the raw cover T. Examples of the material of the pad 61 include an SS material, and the transfer surface 12 is preferably configured using a silicon pad or the like.

2. Tire Marking Method Next, a tire marking method using the above-described tire marking device will be described.

  First, the ink 17 is supplied from the ink pot 31 to the concave portion of the marking portion 15 by pressing the ink supply surface against the marking portion 15 of the marking surface 10 of the plate P1. The plate P <b> 1 supplied with the ink 17 is then conveyed to below the pad 61.

  Next, the pad 61 is lowered and the transfer surface 12 is pressed against the marking portion 15, whereby the ink 17 is transferred from the concave portion of the marking portion 15 to the transfer surface 12. Thereafter, the pad 61 to which the ink 17 has been transferred is conveyed to above the raw cover T.

  Next, the raw cover T is raised and the surface of the raw cover T is pressed against the transfer surface 12, whereby the ink 17 is transferred from the transfer surface 12 to the surface of the raw cover T, and the raw cover T is marked.

  In the above description, one marking has been described as an example, but complicated marking can also be performed using a plurality of ink pots, plates, and pads.

  While the present invention has been described based on the embodiments, the present invention is not limited to the above embodiments. Various modifications can be made to the above-described embodiments within the same and equivalent scope as the present invention.
