Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a net that is detachably attached to a gas cylinder, and more particularly to a net for protecting the surface of a gas cylinder during transportation and handling.

[Prior Art] A cylinder filled with liquefied gas or compressed gas and used for storage and transportation is a cylindrical container made of steel and has a considerable weight. Therefore, they tend to be handled roughly, and the outer wall surface of the cylinder is prone to scratches, peeling of paint, and rust.

By the way, for example, semiconductor manufacturing factories, i.e. IC
In factories, garbage and dust are extremely disliked, and various treatments are carried out in clean rooms. Therefore, if the outer walls of cylinders delivered to such factories are scratched or the paint peels off, this is undesirable as rust and dust are generated, and some countermeasures are required. However, conventional countermeasures include repeatedly painting as appropriate,
The reality is that workers clean the surfaces of the cylinders when they are delivered to remove rust and other debris.

[Purpose of the invention] Therefore, the purpose of the invention is to provide a protective net for cylinders that prevents the outer walls of cylinders from coming into direct contact with each other when handling the cylinders, thereby preventing scratches that may cause rust or the like. There is something to do.

[Configuration of the invention] According to the invention, in a gas cylinder protective cover net that is detachably attached to a gas cylinder,
A synthetic resin net consisting of an inner strand in contact with the outer surface of the gas cylinder and an outer strand arranged outside the inner strand to intersect with the inner strand is made of a cylindrical body with an inner diameter smaller than the outer diameter of the gas cylinder to which it is attached. The outer strand extends linearly along the longitudinal direction of the gas cylinder, and the inner strand runs diagonally with respect to the outer strand.

[Operations and Effects of the Invention] Therefore, the sides of the cylinder are substantially protected by the net, and the cylinder can be protected from external impacts. Therefore, even if something hits the product during handling or transportation, the coating will not peel off or get scratched, so rust will not occur. Therefore, when the product is delivered to an IC factory or the like, cleaning work such as removing rust is not necessary, at least on the sides. Because the net is cylindrical, the bottom of the cylinder is not protected, so it is only necessary to clean the bottom. And a clean state is always maintained.

In this way, the protective cover net is attached to the outer wall of the cylinder to prevent paint peeling and scratches on the cylinder's surface, which tend to occur during transportation. Because it is done,
It is desirable that the net is effective in preventing the load from collapsing. Furthermore, since the net is attached to and removed from the cylinders as necessary, it is desirable that the net be easy to attach and detach, and furthermore, it is necessary that the net be easy to pull out the cylinders stacked in bales. Also, since cylinders are heavy, transportation is carried out by standing the cylinders at a slight incline, with a part of the periphery of the bottom touching the ground, and rotating the cylinders by hand. Sometimes it is desirable for the net to be in close contact with the surface of the cylinder.

To this end, the net according to the invention is constructed such that the outer strands run straight in the longitudinal direction and the inner strands run obliquely to the outer strands. The net is formed into a cylindrical shape, and its inner diameter is smaller than the outer diameter of the cylinder by a predetermined dimension, as will be described later. Since the outer strands run in a straight line in this way, when the cylinders stacked in bales are pulled out in the axial direction, each strand can be easily pulled out without causing any pulling resistance. Also, since the inner strand runs diagonally, applying force from above to below will increase the diameter of the net.
That is, the net diameter changes depending on the direction of the force applied to the net. Therefore, the above-mentioned structure of the inner strand allows for easy attachment and detachment of the inner strand to the cylinder, and also allows the inner strand to be installed at a portion of the periphery of the bottom of the cylinder.
Then, when carrying the cylinder by rotating it by hand,
When you turn the cylinder counterclockwise, the net will contract in diameter and come into close contact with the cylinder. Therefore, a net with good transportability can be obtained.

[Examples] Examples of the present invention will be described below with reference to the drawings.

Now, in FIGS. 1 and 2, the net N embodying the present invention is composed of an outer strand 2 and an inner strand 3, and is attached to the outer wall of the body of a cylinder 4.

Outer strand 2 and inner strand 3
The net itself is well known and is made of soft synthetic resin. The entire cylinder is formed into a cylindrical shape, and its inner diameter is about 0.6 to 0.98 of the outer diameter of the cylinder.

The inner strand 3 is in contact with the outer surface of the cylinder 4, and the outer strand 2 is located outside the inner strand so as to contact an external object. The outer strand 2 runs in the axial or longitudinal direction of the cylinder, as also shown in FIG. The inner strand 3 runs diagonally, that is, upwardly to the right, with respect to the outer strand 2.

Since the net N according to this embodiment is constructed as described above, when a force is applied to the net N in the direction of arrow B in FIG.
Since it runs diagonally, that is, upward to the right, the diameter is expanded. Therefore, it can be easily attached to and detached from the cylinder 4. Also, once installed, the diameter of the net N is smaller than the diameter of the cylinder 4, so it fits well into the cylinder.

Also, if the inner strand 3 runs diagonally, the cylinder 4
When carrying the cylinder while standing it upright and rotating it in the direction of arrow C with the right hand R, the diameter of the net will be reduced. Therefore, during transportation, the Net N sticks closely to the cylinder and does not slip, resulting in particularly good workability. Furthermore, as shown in Fig. 4, even when pulling out a plurality of cylinders 4, 4, etc. stacked in bales on a truck in the axial direction, the outer strands of this net run in the longitudinal direction, which hinders work efficiency. There's nothing to do. Since the net is made of synthetic resin, it is clear that it has elasticity, prevents the load from collapsing, and protects the cylinder during handling as well as during transportation.

[Effects] As detailed above, according to the present invention, the cylinder protective cover net protects the outer surface of the cylinder and is made of synthetic resin.
It has cushioning properties and prevents loads from collapsing. In addition, since the inner strand runs diagonally, although it is easy to attach and detach, when transporting it by hand, the net sticks tightly to the outer wall of the body of the cylinder and does not come off, which impairs work efficiency. Nothing happens. Furthermore, since the outer strand runs in the longitudinal direction, it does not reduce the workability of drawing out the cylinder. Therefore, according to the present invention, the cylinder is protected without reducing the handling efficiency of the cylinder, thereby preventing the formation of scratches on the outer wall of the cylinder and peeling of the paint, prolonging the life of the cylinder, and making it suitable for use in IC factories. When applied to a cylinder, it can be used as a cylinder that does not generate dust due to the scratches or peeling of the paint, and is extremely effective in semiconductor manufacturing, which requires dust-free production.
