[Embodiment] An embodiment of a marking device for a gas container according to the present invention will be described below with reference to the drawings.

In this embodiment, as shown in FIGS. 1 and 2, a structure is shown in which marking is performed from the lower side of the gas container B.

The gantry 1 supporting the gas container B has a base 11 installed horizontally, a support leg 12 standing on the base 11 at a certain height, and gas containers B, B supported by the support leg 12. ',
In particular, two left and right bearing shafts 13 arranged in parallel in the horizontal direction with a space slightly narrower than the diameter of the gas container B '.
And a roller 14 coaxially rotatably provided at a plurality of positions on the bearing shaft 13.

In this gantry 1, the gas containers B are rotatably supported by left and right rollers 14 so that the axis of the gas container B becomes horizontal. Further, when the worker M tries to rotate the gas container B by input, the roller 14 is rotated so that the gas container B can be rotated around its axis.

The pedestal 1 can be installed independently, but as shown in FIG. 4, it can be installed adjacent to the valve mounting mechanism V or the like in the reinspection equipment to enable continuous work. it can. That is, a transfer mechanism C such as a belt conveyor for transferring the gas container B in the standing state is provided from the valve mounting mechanism V in which the valve is normally mounted in the standing state of the gas container B, and is provided at the end of the transfer mechanism C. The roller 14 is integrally attached to the installed overturning mechanism D, and the roller 14 is shared with the overturning mechanism D so that the roller 14 can be rotated by 90 degrees, and the overturning mechanism D causes the gas container B to overturn from the standing state to the lying state. It is also good to mark the condition.

A printer 2 for marking the peripheral surface of the gas container B supported by the roller 14 below the roller 14 is provided at a central portion between the support shaft 13 and the roller 14 of the gantry 1.

This printer 2 has a marking material box 21 for storing marking materials such as ink and paint, and a print head 22 having a large number of small holes 22 'which come into contact with the peripheral surface of the gas container B and eject the marking material. The control unit 23 for selectively controlling the small holes 22 'of the print head 22 on which the marking material is ejected, and the rotation transmission to the roller 14 of the pedestal 1 via the belt 24' to eject the marking material on the control unit 23. A rotary encoder 24 for transmitting the selection timing of each small hole 22 'of the print head 22 and a marking start switch 25 for operating each of the above parts.

In such a printer 2, as the gas container B rotates, the marking material is sequentially ejected at predetermined points on the peripheral surface of the gas container B, and these points gather to form dot display. Necessary items such as characters will be displayed. An input mechanism or a reading mechanism is connected to the control unit 23 so that the contents to be marked (selection control of the small holes 22 'of the print head 22) can be stored in advance or can be instructed immediately before. ing.

Then, the print head 22 of the printer 2
Is a plurality is provided so as to be able to perform marking a plurality of rows simultaneously by 1 rotation of the gas container B.
In addition, the pedestal 1 is supported by being supported by an up-and-down table 3 that can move up and down so that the gas containers B and B'having different diameters can surely abut .
It is arranged at a central portion between the rollers 14 .

The lifting platform 3 is supported on the base 11 of the pedestal 1 so as to be vertically movable by a spring member 31, and the lifting plate 32 to which the print head 22 of the printer 2 is fixed, and the platform 1 supported by the lifting plate 32. The bearing shaft 13 and the roller 33 located below the central portion of the roller 14 and rotatably contacting the peripheral surface of the gas container B. This lift 3 is shown in FIG.
As shown in the above, the state of being supported on the rollers 14 of the gantry 1
At least in the gas containers B and B'having different diameters
At the height at which the roller 33 comes into contact with the peripheral surface of the container B, the spring material 31 is used.
Gas container B or B'having different diameters
Even if the container is supported on roller 14, roller 33
When the gas containers B and B'are rotated by contacting the surfaces,
It rotates with LA14.

According to such an embodiment, the operator M simply rotates the gas container B on the gantry 1 to automatically mark the necessary indication on the peripheral surface of the gas container B. Such work of attaching and peeling a mask does not require time and work performance is improved. In particular, since the printer 2 is provided with the control unit 23 and marking is performed under automatic control in which the marking material is ejected from the small holes 22 ′ of the print head 22 selected by the control unit 23 ,
Precise marking on a specified location on the peripheral surface of container B
Is possible. Then, the print head 22 of the printer 2
Performed but because it is vertically movable is supported on the lifting platform 3, different gas containers B in diameter, 'even in the case of the marking relative to, or different gas container B, B' B different markings for each single In this case as well, it is possible to prevent marking mistakes without lowering work performance.

Further, since a conventional mask is not used, the phenomenon that the paint accumulated in the notch of the mask does not flow, and since the gas container B is horizontal, the peripheral surface of the gas container B is prevented. Since the attached marking material does not hang down, the marking finish is good. In particular, since the marking is a dot display and more marking material than necessary is not attached to the peripheral surface of the gas container B, the drying time of the marking material can be shortened.

As described above, in addition to the illustrated embodiment, the printer 2
It is also possible to make it an example of the structure in which is marked from the upper side of the gas container B. Incidentally, in the case of such an embodiment, a structure in which the printer 2 is integrally rotated with the gantry 1 can be applied to the laterally tumbling structure of the gas container B as shown in FIG.

Further, it is possible to adopt an embodiment in which the gas container B is rotated by other driving means such as mechanical.

[0021]

As described above, the gas container marking device according to the present invention can automatically mark the peripheral surface of the gas container by simply rotating the gas container. Since there is no need for the work of wearing and peeling, there is an effect that the work performance of marking is improved.

Further, since the printer is used to control the marking, there is an effect that it is possible to prevent the marking mistake which is caused by the operator making a mistake in selecting the mask.

Further, since the gas container is marked horizontally without using a conventional mask, the marking material does not flow and the marking finish is improved.

Further, unlike the conventional mask, since a large amount of marking material is not attached to the gas container, there is an effect that the drying time of the marking material can be shortened.
