Description

Technical Field

[0001] This invention relates to gas cylinder cabinets.

[0002] This application claims priority based on Japanese Patent Application No. 2021-060644, filed on March 31, 2021, the contents of which are incorporated herein by reference. Background Technology

[0003] Gas cylinder cabinets are widely used as devices for supplying various gases. In such cabinets, gas cylinders filled with various gases are stored upright in a storage space with a door for accessing and placing the cylinders. Furthermore, when using cylinders whose remaining quantity needs to be managed by weight, components such as load cells capable of measuring weight are required. Therefore, a base is provided under the cylinders at the bottom of the cabinet. Thus, when storing the cylinders in the storage space, the cylinders must be raised above the height of the base at the bottom of the cabinet and placed on the base plate of the storage space.

[0004] However, depending on the contents, some gas cylinders weigh over 100kg, requiring the aforementioned storage operation to involve lifting the cylinder, which is a strenuous task for the operator. Furthermore, when placing the cylinder into the narrow storage space, it must be rotated to align with the metal cap, thus hindering operability.

[0005] Patent Document 1 discloses a gas cylinder cabinet with a horizontal movement mechanism for moving gas cylinders disposed in a storage space horizontally along the inlet and outlet directions of the storage space. According to this gas cylinder cabinet, by combining guide rails and wheels, the gas cylinder support holding the gas cylinders can move freely horizontally.

[0006] Patent document 2 discloses a gas cylinder handling and storage system that enables easy storage, retrieval, and transport of gas cylinders into and out of a gas cylinder cabinet. According to this system, gas cylinders are easily stored, retrieved, and transported into the cabinet using a gas cylinder cabinet and a gas cylinder transport trolley. The gas cylinder cabinet has a worktable at the bottom of the space where the gas cylinders are stored, which can move in both inward and outward directions. The gas cylinder transport trolley has forks that engage with flanges of transport adapters mounted on the gas cylinders for lifting and lowering.

[0008] Patent Document 2: Japanese Patent Application Publication No. 2001-106086

[0009] However, in the gas cylinder cabinet disclosed in Patent Document 1, the operator needs to place the gas cylinder on the gas cylinder support inside the gas cylinder cabinet.

[0010] Similarly, in the gas cylinder cabinet disclosed in Patent Document 2, the operator needs to place the gas cylinder on the workbench inside the gas cylinder cabinet.

[0011] Furthermore, in the gas cylinder cabinets disclosed in Patent Documents 1 and 2, it is difficult to rotate the gas cylinder within the storage space. Summary of the Invention

[0012] The present invention was made in view of the above circumstances, and its object is to provide a gas cylinder cabinet that allows an operator to easily place gas cylinders in a designated position within the cabinet and easily rotate the gas cylinders.

[0013] To accomplish the above-mentioned tasks, the present invention adopts the following technical solution.

[0021] [5] According to the gas cylinder cabinet described in [3], the mounting surface is the upper surface of the plurality of rollers.

[0022] [6] According to the gas cylinder cabinet described in [4], the mounting surface is the upper surface of the plurality of rollers.

[0023] [7] The gas cylinder cabinet according to any one of [1] to [6] includes: a weight measuring component located below the roller unit and used for measuring the weight of the gas cylinder or a height adjusting component at the same height as the weight measuring component.

[0024] [8] According to the gas cylinder cabinet described in [7], the weight measuring component and the height adjusting component are interchangeable.

[0030] Hereinafter, embodiments are shown with reference to the accompanying drawings, and the present invention will be described in detail.

[0031] Furthermore, in the accompanying drawings used in the following description, the feature parts may be enlarged for ease of understanding and convenience, and the size ratios of each structural element may not be the same as the actual dimensions.

[0032] <Gas Cylinder Cabinet>

[0033] First, the structure of a gas cylinder cabinet as one embodiment of the present invention will be described.

[0034] Figures 1-4 This is a schematic diagram illustrating a gas cylinder cabinet according to an embodiment of the present invention.

[0035] like Figure 1 As shown, the gas cylinder cabinet 1 of this embodiment is generally constructed including the following components: a housing 2 having a storage space S for storing the gas cylinder B in an upright state inside; a roller unit 3; a weighing sensor (weight measuring component) 4 and a spacer (height adjustment component) 5.

[0036] The gas cylinder cabinet 1 stores the gas cylinders B in an upright position within the storage space S of the shell 2.

[0037] The housing 2 is a storage box having one or more storage spaces S for storing gas cylinders B in an upright position inside. Furthermore, a roller unit 3, a weighing sensor 4, and a spacer 5 are arranged at the bottom of the storage space S. Specifically, in... Figure 1In the storage space S on the left, a weighing sensor 4 is arranged on the bottom surface, and a roller unit 3 is arranged on the upper surface of the weighing sensor 4. Furthermore, in... Figure 1 In the storage space S on the right side, a spacer 5 is arranged on the bottom surface, and a roller unit 3 is arranged on the upper surface of the spacer 5. In addition, the gas cylinders B are placed on the upper surface of the roller unit 3 in an upright state.

[0038] In addition, the housing 2 has guide components 6 and 7, which are used to support the gas cylinder B, which is placed on the upper surface of the roller unit 3 in an upright state.

[0039] Guide components 6 and 7 constrain the movement of gas cylinder B within and outside the storage space. Furthermore, guide components 6 and 7 are preferably configured not to exert vertical force on the roller unit 3 and gas cylinder B (described later).

[0040] Roller unit 3 is located near the bottom of storage space S.

[0041] like Figure 2 and Figure 3 As shown, the roller unit 3 has: a pair of support members (support parts) 8, 8 extending in the direction of the inward and outward directions of the storage space (in the direction of the arrows shown); and a plurality of rollers 9, 9... rotatably supported between the support members (support parts) 8, 8, and arranged at predetermined intervals in the inward and outward directions of the storage space. Through this roller unit 3, the gas cylinder B can move in an upright position along the inward and outward directions of the storage space on the upper surfaces of the plurality of rollers 9, 9...

[0042] There are no particular limitations on the diameter and number of rollers 9. The required strength and area can be appropriately selected according to the specifications of the gas cylinder B used.

[0043] And, as Figure 2 As shown, in the gas cylinder cabinet 1 of this embodiment, when the gas cylinder B is stored in the storage space S in an upright state, the gas cylinder B is placed on the upper surface of the plurality of rollers 9, 9... constituting the roller unit 3. That is, the roller unit 3 has a mounting surface 3A for placing the gas cylinder B in an upright state, and the upper surface of the plurality of rollers 9, 9... constituting the roller unit 3 is the mounting surface 3A of the gas cylinder B.

[0044] In other words, the upper surfaces of the multiple rollers 9, 9... constituting roller unit 3 are the moving surface and the mounting surface 3A of gas cylinder B.

[0045] The load cell 4 is a weight measuring component that measures the weight of an object placed on the measuring surface. For example... Figure 1 or Figure 3 As shown, the weighing sensor 4 is at the bottom of the storage space S, located below the roller unit 3.

[0046] The weighing sensor 4 has a base plate 10 and a pair of strip weighing sensors 11, 11 arranged parallel to each other at both ends of the base plate 10 and extending inward and outward in the direction of the storage space (as shown by the arrows in the figure). The roller unit 3 is supported on the upper surface of the weighing sensor 4 by placing the support members 8, 8 of the roller unit 3 on the upper surfaces of the pair of strip weighing sensors 11, 11. Thus, the weighing sensor 4 can measure the weight of the cylinder B with only the roller unit 3 present, or with the cylinder B placed on the mounting surface 3A of the roller unit 3. Therefore, the remaining amount of cylinder B can be determined from the weight of cylinder B, and the replacement time of cylinder B can be predicted. Thus, the cylinder cabinet 1 can be easily managed.

[0047] Spacer 5 is a height adjustment component used to adjust it to be the same height as the load cell (weight measuring component) 4. For example... Figure 1 or Figure 3 As shown, the spacer 5 is the bottom of the storage space S, located below the roller unit 3.

[0048] like Figure 1 As shown, in the gas cylinder cabinet 1 according to this embodiment, the height of the spacer 5 is the same as the height of the weighing sensor 4, such that the mounting surface 3A of the roller unit 3 provided on the weighing sensor 4 and the mounting surface 3A of the roller unit 3 provided on the spacer 5 have the same height. Therefore, when gas cylinder B is placed in the gas cylinder cabinet 1 or when gas cylinder B is retrieved from the gas cylinder cabinet 1, a general-purpose gas cylinder transport trolley or the like can be used.

[0049] In the gas cylinder cabinet 1 of this embodiment, at least some or all of the roller units 3 can be moved from their positions within the housing 2 when the gas cylinder B is placed in an upright state. Since the roller units 3 are movable in this way, the load cells 4 and spacers 5 located below the respective roller units 3 can be appropriately replaced. For example, if it is necessary to manage the remaining amount of gas cylinder B by weight, the load cells 4 are provided below the roller units 3; if it is not necessary to manage the remaining amount of gas cylinder B by weight, the spacers 5 can be used. Therefore, it is unnecessary to place the load cells 4 at the bottom of all storage spaces S.

[0050] Furthermore, in the gas cylinder cabinet 1 of this embodiment, when the gap between the storage space S in the housing 2 and the gas cylinder B is small, preferably, the roller unit 3 can be freely detached from the storage space S. This makes it easy to replace the weighing sensor 4 and the spacer 5.

[0051] like Figure 4As shown, in the gas cylinder cabinet 1 according to this embodiment, since the roller unit 3 is located near the bottom of the storage space S, even if the gap between the storage space S and the gas cylinder B is small, the operator can easily move the gas cylinder B in an upright position along the inward and outward directions of the storage space within the storage space S. Furthermore, since the gas cylinder B can be easily rotated on the mounting surface 3A of the roller unit 3, the orientation of the metal cap of the gas cylinder B can be easily modified.

[0052] Furthermore, in traditional gas cylinder cabinets, when managing the remaining amount of gas cylinders by weight, it is necessary to install weight measuring components such as weighing sensors at the bottom of the storage space inside the housing. Therefore, it is difficult to install rotating rollers at the bottom of the storage space inside the housing, i.e., the base where the gas cylinders are placed.

[0053] In contrast, in the gas cylinder cabinet 1 according to this embodiment, the rotating roller for moving the gas cylinder is unitized, so that it can be moved from the bottom of the storage space inside the housing (and can be freely detached). Since the weighing sensor 4 is arranged below the roller unit 3, and the weight of the gas cylinder B can be measured for each roller unit 3, it is possible to balance the management of the remaining amount of the gas cylinder and the ease of moving the gas cylinder.

[0054] As described above, according to the gas cylinder cabinet 1 of this embodiment, the operator can easily move the gas cylinder B on the upper surface (placement surface 3A) of the roller unit 3 at a predetermined setting position within the housing 2, and easily rotate the gas cylinder B on the placement surface 3A.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the specific structure is not limited to this embodiment, and designs that do not depart from the spirit of the present invention are also included. For example, the above-described gas cylinder cabinet 1 is constructed as having a roller unit 3 having a plurality of rollers 9, 9... that are rotatably supported between support members 8, 8. However, this is not the limitation. The gas cylinder cabinet of the present invention can also be constructed with a locking mechanism that allows the plurality of rollers 9, 9... to rotate freely when the roller unit 3 moves the gas cylinder B, and restricts the rotation of the plurality of rollers 9, 9... when the roller unit 3 holds the gas cylinder B. Thus, the upper surfaces of the plurality of rollers 9, 9... constituting the roller unit 3 can be used as movable surfaces when moving the gas cylinder B, and as fixed surfaces when holding the gas cylinder B. Therefore, the gas cylinder B can be moved easily and can be safely stored.

[0056] Furthermore, in the gas cylinder cabinet 1 of the above embodiment, an example was described where the roller unit 3 can be detached from the housing 2 and moved from its normal installation position, but this is not the limitation. The gas cylinder cabinet of the present invention can also be configured such that the roller unit 3 can be moved from its normal installation position while a portion of the roller unit 3 is still connected to the housing 2. For example, as Figure 2 As shown, the roller unit 3 can also be configured to extend from the inlet and outlet sides of the housing 2 along... Figure 2 The arrow shown is pointing inwards.

[0057] Furthermore, in the gas cylinder cabinet 1 of the above embodiment, the structure in which the weighing sensor 4 or the spacer 5 is located below the roller unit 3 has been described as an example, but it is not limited thereto. The gas cylinder cabinet of the present invention can also be used with only the roller unit 3.

[0058] Furthermore, in the gas cylinder cabinet 1 of the above embodiment, the structure of the weighing sensor 4 having a pair of strip weighing sensors 11, 11 was described as an example, but it is not limited to this. Weighing sensors of any shape can also be appropriately used in the gas cylinder cabinet of the present invention.
