 The present invention relates to a marking device for a gas container. More specifically, when re-inspecting and reusing a used gas container, a marking device that displays the type of gas, the filling deadline, the contact information of the dealer, etc. on the peripheral surface in the re-inspection process of the gas container. Regarding

[0002]

[Prior Art]

 Conventionally, as a marking means in the re-inspection process of a gas container, for example, a mask with a predetermined notch is attached to the circumferential surface of the gas container, and the coating is sprayed from above the mask. It is known to remove the mask from the peripheral surface of the gas container immediately after application or after the paint is dried.

Such a conventional marking means has a problem that the work performance is low because the work of attaching and peeling the mask is required. Furthermore, since the paint easily flows from the notch of the mask, there is a problem that the marking finish becomes defective.

【Example】

 An embodiment of a gas container marking device 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 surface side of the gas container B.

The gantry 1 supporting the gas container B has a base 11 installed horizontally, a support leg 12 erected at a certain height on the base 11, and a diameter of the gas container B supported by the support leg 12. It comprises two bearing shafts 13 arranged in parallel in the horizontal direction at a slightly narrower interval, and rollers 14 rotatably and coaxially provided at a plurality of positions on the bearing shaft 13.

In this gantry 1, the gas container B can be supported so that its axis is horizontal by the roller 13 contacting the peripheral surface of the gas container B. Further, when the worker M tries to rotate the gas container B by input, the roller 13 is rotated so that the gas container B can be rotated around the axis.

This 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 conveyer 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 at the end of the transfer mechanism C. The above is integrally attached to the installed overturning mechanism D, and the roller 14 is shared with the overturning mechanism D so as to be rotatable by 90 degrees, and the overturning mechanism D changes the gas container B from the standing state to the standing state. It is also good to mark in the state of being overturned.

Below the support shaft 13 and the rollers 14 of the gantry 1, a printer 2 for marking on the lower surface of the peripheral surface of the gas container B supported by the gantry 1 is provided.

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

In such a printer 2, as the gas container B is rotated, the marking material is sequentially ejected at predetermined points on the lower surface of the circumferential surface of the gas container B, and these points are collected to form dots. The necessary items such as characters will be displayed by the display. 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. Is becoming

A plurality of print heads 22 of the printer 2 are provided so that a plurality of rows of markings can be simultaneously made by one rotation of the gas container B, and gas containers B ′ having different diameters are respectively provided. It is supported by a lift table 3 that can move up and down so that it can surely contact.

The lifting and lowering third is a lifting plate 32 supported by the base 11 of the pedestal 1 via a spring material 31 and to which the print head 22 of the printer 2 is fixed, and both supporting shafts of the pedestal 1 supported by the lifting plate 32. 13, a roller 33 located below the center of the roller 14 and rotatably abutting the lower end of the peripheral surface of the gas container B.

According to such an embodiment, the worker M simply rotates the gas container B on the gantry 1 so that the necessary display is automatically marked on the peripheral surface of the gas container B. The work performance is improved without the work of sticking and peeling the mask as usual. In particular, the printer 2 is provided with the control unit 23, which can automatically control the selection of the small holes 22 'of the print head 22 through which the marking material is jetted, and the print head 22 of the printer 12 is supported by the lift 3 and moved up and down. Since it is possible, the working performance may be deteriorated even when the marking is performed on the gas containers B and B ′ having different diameters and also when the marking is performed differently for each of the different gas containers B. It is also possible to prevent marking mistakes.

Further, since a conventional mask is not used, the phenomenon that the paint accumulated in the notch of the mask will not flow, and since the gas container B is horizontal, the peripheral surface of the gas container B The marking material adhered to will not hang down, so the marking finish will be 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 may be an embodiment having a structure in which the upper surface side of the gas container B is marked from the top. 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 another driving means such as mechanical.

[0021]

[Effect of the device]

 As described above, the gas container marking device according to the present invention can automatically perform marking on the peripheral surface of the gas container simply by rotating the gas container. Since no labor is required, there is an effect that the marking work performance is improved.

Further, since the marking is controlled by using the printer, 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, there is an effect that the marking material does not flow and the marking finish becomes good.

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.
