DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transporting a gas container filled with a high-pressure gas such as LP gas.

[0002]

2. Description of the Related Art Conventionally, as this kind of transport device, for example, as disclosed in Japanese Patent Application Laid-Open No. HEI 8-119578, a pad for sucking and holding a container and an elevating device for the pad are provided. In some cases, the pad is lowered to place the pad on the upper portion of the container, the inside of the pad is depressurized to adsorb the pad to the container, and then the pad is raised by driving a lifting device to lift the container.

[0003]

Although the above-mentioned conventional transport device can load and unload containers on trucks without requiring a large amount of manpower, it has the following problems related to suction holding of containers. Was. That is, in the conventional transport device, the pad is formed in a shape having a skirt surface along the upper edge surface of the container on the peripheral edge of the central ridge that covers the filling valve of the container, and packing is added to the outer peripheral edge of the skirt surface. Then, when a pad is placed on the upper part of the container, a gap is not formed so that a vacuum leak does not occur. However, LP gas containers are available in various sizes (capacities) such as 15 kg, 20 kg, 30 kg, and 50 kg, and the processing state of the upper edge surface of the container varies depending on the size.
A relatively small one of about 0 kg has a shape with a protective protector surrounding the filling valve (a container with a protector), and a relatively large one of 30 kg or 50 kg has a shape in which the filling valve is covered with a valve cap (cap). Container). In order to be able to hold both the protector-equipped container and the cap-equipped container by air absorption, it is necessary to increase the capacity of the pad and to use a large vacuum device. Since energy and air are consumed, there is a practical problem in terms of cost and the like. In addition, the above-mentioned conventional suction-type transfer device is a type dedicated to a container with a cap capable of reducing the amount of vacuum by reducing the size of the suction pad, but it requires a lot of air to suction and hold a large container of about 50 kg. Since electric energy is consumed, the cost is high, and it takes a long time to evacuate the inside of the pad to a vacuum, and the workability is deteriorated. Furthermore, if a vacuum leak occurs between the suction pad and the upper surface of the container, there is a risk that the container may fall, so there is a doubt about the safety. In addition, maintenance of the vacuum state to prevent this, and the outer periphery of the pad In particular, care must be taken in the maintenance and management of the packing, and the management cost may be high.

[0004] The present invention has been made in view of such a conventional situation, and an object of the present invention is to provide a large-sized type that can safely and surely reduce the air consumption while reducing the air consumption as compared with the conventional suction type transfer apparatus. An object of the present invention is to provide a gas container transfer device which can hold a container, is easy to manage, and has excellent workability. Another object of the present invention is to provide a gas container transfer device that can easily cope with a small container with a protector.

[0005]

In order to achieve the above-mentioned object, a gas container conveying device according to the present invention has an engaging member which engages with an engaged groove formed on a lower edge of a valve cap, and holds the engaging member. The gist comprises an engagement body holding member and a container holding device with a cap having a lock mechanism for urging the engagement body inward to lock the engagement state with the engaged groove.

That is, the valve cap mounted on the filling valve of the LP gas container is provided with a concave groove at the lower edge thereof. According to the apparatus of the present invention having the above structure, the engaging body is The gas container can be suspended and held via the valve cap by engaging with the concave groove (engaged groove) and locking the engaged state. The concave groove (engaged groove) is formed along the circumferential direction of the valve cap, and the engaging body is preferably disposed along the circumferential direction of the valve cap. Examples of the engagement body include a protrusion formed along the circumferential direction of the valve cap, and a plurality of balls provided at appropriate intervals.

[0007] As an example of a container holding device with a cap, the engaging body is held on the peripheral wall of an engaging body holding member composed of an inner frame body that covers the valve cap from above so as to be able to protrude in and out. The lock mechanism is formed by providing an outer frame body that pushes the engagement body inward when the actuator is at the lowered position and freely locks the engagement state with the engaged groove from the outer periphery.

The gist of the present invention is to provide a gas container conveying device having a protector-equipped container holding device for holding a container by suspending a protector surrounding a filling valve at an upper portion of the container. The container holding device with a protector rotatably supports a pair of left and right hanging arms having a hook at the lower end, and inserts both hooks into the left and right openings for the handle of the protector to hold the protector. Formed.

In this case, it is possible to suspend and hold a container with a protector provided with a protective protector surrounding the filling valve via the protector.

As an example of the container holding device with a protector, a pair of left and right hanging arms arranged outside the outer frame body, and these hanging arms are arranged at a standby position where the lower end hooking portion is higher than the lower end of the inner frame body. And, a lifting device that raises and lowers between an operating position in which the lower end hooking portion faces the opening, and a closed position in which the lower hanging portion is inserted into the opening in the operating position, There is a configuration provided with a rotating mechanism for rotating the lower end hooking portion between an open position outside the opening. In such a configuration, a part of the container holding device with the cap can be used also as a component of the container holding device with the protector, which is useful for reducing the size of the device and reducing the manufacturing cost.

[0011] By the way, the gas container conveying device of the present invention comprises:
While the above-described container holding device with a cap is provided as an essential requirement, the container holding device with a protector is selectively provided, but these holding devices are, for example, a traveling rail or a traversing rail extending in a direction perpendicular to the traveling rail. Equipped with a machine frame that is movably mounted, with the container with cap or the container with protector held by the container holding device,
The container with cap or the container with protector is transported by moving the machine frame along the traveling rail or traversing along the traversing rail.
