Description

[Technical Field]

[0001] The present invention relates to a packaging box for modifying the lifting height of a hoist such as an electric chain hoist. [Background technology]

[0002] Hoists such as the electric chain hoist disclosed in Patent Document 1 are easy to install and are used in a variety of work sites such as factories. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7432288 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, the lifting height of an electric chain hoist can be modified by changing the chain, storage container, and pushbutton cable assembly. In this way, the lifting height of a hoist can be modified, and if necessary depending on the equipment at the work site or the shape of the load being lifted, the lifting height may be changed at the work site after shipping. When modifying the lifting height, typically, parts for the lifting height modification, such as a chain of the required length, a storage container to store it, and a pushbutton cable assembly corresponding to the required lifting height, are individually ordered and replaced at the work site. The lifting height modification work is generally performed with the hoist body suspended by a hoist. However, because the hoist hook rotates, the hoist body is not fixed, making the work difficult.

[0005] Therefore, an object of the present invention is to provide a packaging box for lifting height modification that can improve the workability of modifying the lifting height of a hoist. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the present invention provides a packaging box for lifting height modification that packs parts for modifying the lifting height of a hoist, the packaging box for lifting height modification having a fixing portion at the top that receives and fixes the main body of the hoist. [Effects of the Invention]

[0007] According to the present invention, the workability of modifying the lifting height of a hoist can be improved. [Brief explanation of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] -Hoisting machine- Fig. 1 is a front view showing an example of the configuration of an electric chain hoist, which is an example of a hoist, and Fig. 2 is a side view thereof. As an example of a hoist whose lifting height is modified using a packaging box for lifting height modification (hereinafter referred to as packaging box) according to the present invention, the schematic configuration of an electric chain hoist will be described below with reference to Figs. 1 and 3.

[0011] The electric chain hoist 100 includes an electric motor 1, a reducer 2, an electromagnetic brake 3 (FIG. 3), an upper hoist 4, an operation input device 5, a storage container (chain bucket) 6, a sprocket 7, a load block (hook) 8, a chain 9, and a control unit 10.

[0012] The upper hoist 4 is a component for suspending and installing the electric chain hoist 100, and is attached to the upper part of the main body 101 of the electric chain hoist 100, which is configured to include the exterior covers 13 and 14. The exterior covers 13 and 14 are connected adjacent to each other in the horizontal direction, and the direction in which the exterior covers 13 and 14 are connected (the left-right direction in FIG. 2 ) is the longitudinal direction of the main body 101. The main body 101 houses components such as the electric motor 1, reducer 2, electromagnetic brake 3, sprocket 7, and control unit 10 described above.

[0013] The rotation output of the electric motor 1 is reduced in speed by the reducer 2 and transmitted to the sprocket 7. The electromagnetic brake 3 is attached to the electric motor 1 and stops the rotation of the electric motor 1 by the electromagnetic brake 3. A chain 9 meshes with the sprocket 7, and as the sprocket 7 rotates, the chain 9 is unwound and reeled out, causing the load block 8 to rise and fall. A storage container 6 is attached to the main body 101 of the electric chain hoist 100, and the reeled chain 9 is stored in the storage container 6. A control unit 10 controls the operation of the electric motor 1 and the electromagnetic brake 3. The operation input device 5 is connected to the control unit 10 via a power cable 11 and an operation cable 12. The operation input device 5, the power cable 11, and the operation cable 12 form a push button cable set 15.

[0014] Fig. 3 is an example of an electric circuit diagram of the electric chain block illustrated in Fig. 1. The circuit of the electric chain block 100 will be outlined with reference to Figs. 1 to 3.

[0015] When the up operation button of the operation input device 5 is pressed, current is passed through the electromagnetic contactor (coil) 23 via the contacts of the overwinding prevention device 22 in the control unit 10, which closes the electromagnetic contactor (contacts) 26 and passes current through the contacts of the overwinding prevention device 25 to the electric motor 1. At the same time as the electric motor 1 is energized, current is also passed through the electromagnetic brake 3, which opens the electromagnetic brake 3 and causes the electric motor 1 to rotate. As described above, the rotational power of the electric motor 1 is reduced to a predetermined rotational speed by the reducer 2 and transmitted to the chain 9 by the sprocket 7 connected to the final reduction stage. The load block 8 is then hoisted up and down via the chain 9, and the suspended load is raised and lowered. When hoisting, the portion of the chain 9 opposite the load block 8 is stored in the storage case 6 attached to the main body 101 of the electric chain hoist 100, and when lowering, it is let out from the storage case 6.

[0016] - Packing box for lifting height modification - Fig. 4 is a plan view of a packing box according to one embodiment of the present invention, Fig. 5 is a three-view diagram of a fixing base provided on the packing box, Fig. 6 is a diagram showing a state in which the main body 101 of the electric chain hoist 100 is fixed to a first fixing part 41A (described later), and Fig. 7 is a diagram showing a state in which the main body 101 of the electric chain hoist 100 is fixed to a second fixing part 41B (described later). The outer box 50 is omitted from Figs. 6 and 7.

[0017] The packaging box 30 is a box for packaging parts for remodeling the lifting height of a hoist, or in this embodiment, the electric chain hoist 100. The parts for remodeling the lifting height are parts that are installed in place of existing parts in the hoist whose lifting height is to be remodeled and are parts that correspond to the conditions under which the hoist is used at the work site. In this embodiment, for example, the parts for remodeling the lifting height include a chain 9 of a length corresponding to the lifting height required for the electric chain hoist 100 at the work site, a storage container 6 for storing the chain 9, and a push button cable assembly 15 corresponding to the required lifting height. When these parts for remodeling the lifting height are procured at the work site, the desired set of parts for remodeling the lifting height are packed into one packaging box 30 and delivered to the work site from the supplier (e.g., the manufacturer of the electric chain hoist 100). Furthermore, parts removed from the electric chain hoist 100 when the lifting height is remodeled at the work site are stored in the packaging box 30 on the spot and returned to the manufacturer.

[0018] The packaging box 30 comprises an outer box 50 with a bottom and a fixed base 40 which also serves as a partition to separate the interior of the outer box 50. The outer box 50 is the exterior of the packaging box 30 and is, for example, a rectangular box made of, for example, plastic (for example, plastic cardboard), paper (for example, cardboard), or wood, and is preferably made of a recyclable material. The fixed base 40 is, for example, made of paper (hard paper) or wood, and is also preferably made of a recyclable material. It is desirable that these materials are strong enough to be used repeatedly.

[0019] The fixing base 40 has a lower part 45 that also serves as a partition that divides the interior of the outer box 50, and an upper part 42 that has a fixing part 41 and is supported by the lower part 45. The fixing part 41 is a part that receives and fixes the main body 101 of the electric chain hoist 100, and is provided at the top of the packaging box 30, that is, on the upper surface of the upper part 42 of the fixing base 40 in this embodiment. In this embodiment, the fixing part 41 is a recess that is formed according to the size and shape of the underside of the main body 101 of the electric chain hoist 100.

[0020] The upper portion 42 of the fixed base 40 includes a plurality of (two in this example) first frames 42A arranged substantially parallel to a first horizontal direction (the left-right direction in FIG. 4), and a plurality of (two in this example) second frames 42B arranged substantially parallel to a second horizontal direction (the up-down direction in FIG. 4). The first frames 42A and the second frames 42B are orthogonal to each other and are arranged in a grid pattern in plan view as shown in FIG. 4. In this embodiment, the first direction and the second direction are orthogonal to each other, with the first frames 42A extending in the second direction (the up-down direction in FIG. 4) and the second frames 42B extending in the first direction (the left-right direction in FIG. 4).

[0021] The fixing portions 41 are located at the longitudinal center of the upper surface of each of the first frames 42A and the second frames 42B. Each fixing portion 41 (hereinafter referred to as the first fixing portion 41A) provided on the two first frames 42A is located between the two second frames 42B. Each fixing portion 41 (hereinafter referred to as the second fixing portion 41B) provided on the two second frames 42B is located between the two first frames 42A. In this embodiment, the first fixing portion 41A and the second fixing portion 41B are recessed portions that are recessed downward and extend upward in the longitudinal direction of the first frame 42A and the second frame 42B, respectively, and are provided across the entire width of the first frame 42A and the second frame 42B, from one end face to the other end face in the width direction. When the main body 101 of the electric chain hoist 100 is placed on the first fixing part 41A, the main body 101 of the electric chain hoist 100 is fixed in a position extending in a first horizontal direction (left-right direction in FIG. 4). When the main body 101 of the electric chain hoist 100 is placed on the second fixing part 41B, the main body 101 of the electric chain hoist 100 is fixed in a position extending in a second horizontal direction (up-down direction in FIG. 4) that is different from the first horizontal direction. In this embodiment, the second direction is a direction perpendicular to the first horizontal direction, so when the main body 101 of the electric chain hoist 100 placed on the first fixing part 41A is relocated to the second fixing part 41B, the main body 101 of the electric chain hoist 100 is rotated 90° horizontally.

[0022] The lower portion 45 of the fixed base 40 includes a plurality of (two in this example) first plates 45A arranged substantially parallel to one another in a first horizontal direction (the left-right direction in FIG. 4 ) and a plurality of (two in this example) second plates 45B arranged substantially parallel to one another in a second horizontal direction (the up-down direction in FIG. 4 ). Both the first plates 45A and the second plates 45B extend vertically. Similar to the first frames 42A and the second frames 42B, the first plates 45A and the second plates 45B are orthogonal to one another and are arranged in a grid pattern in a plan view. The first frames 42A overlap the upper surfaces of the first plates 45A, respectively, and the second frames 42B overlap the upper surfaces of the second plates 45B, respectively. In this embodiment, the first plate 45A and the first frame 42A, and the second plate 45B and the second frame 42B are fitted together with a fitting structure as shown by the dashed lines in Fig. 5, and the upper part 42 is detachable from the lower part 45 of the fixed base 40. Therefore, by removing the upper part 42 from the lower part 45 of the fixed base 40 and attaching another upper part 42 with a fixed part 41 of a different size or shape to the lower part 45 of the fixed base 40, the fixed base 40 can fix electric chain hoists 100 with main bodies 101 of different sizes or shapes.

[0023] Furthermore, as described above, the lower portion 45 of the fixed base 40 functions as a partition that divides the interior of the outer box 50, and the outer box 50 is divided into a plurality of compartments (nine compartments in this example) in a grid pattern by the lower portion 45, thereby providing a first storage compartment 51 that stores parts for modifying the lifting height of the electric chain hoist 100, and a second storage compartment 52 that stores parts that are removed from the electric chain hoist 100 in exchange for the parts for modifying the lifting height. The first storage compartments 51 are two compartments located on both sides of a central hoisting machine fixing space 59 located between the two first fixed portions 41A and the two second fixed portions 41B in a direction (vertical direction in FIG. 4 ) perpendicular to the first direction in which the first fixed portions 41A are aligned, and both compartments exist between the two first plates 45A. The second storage chambers 52 are two chambers located on both sides of the central hoisting machine fixing space 59 in a direction (left and right direction in FIG. 4) perpendicular to the second direction in which the second fixing parts 41B are lined up, and both are located between two second plates 45B. Each of the first storage chambers 51 and second storage chambers 52 is narrower than the central hoisting machine fixing space 59 but wider than the rooms at the four corners.

[0024] As shown in Figure 4, of the parts for modifying the lifting height, the chain 9 (modification chain) and the storage container 6 (modification storage container), which have relatively large volumes, are stored in the first storage chamber 51, while the push button cable assembly 15 (modification push button cable assembly) and the temporary chain attachment 17, which have relatively small volumes, are appropriately stored in the empty rooms at the four corners. Also, as shown in Figure 4, of the parts to be removed from the electric chain hoist 100 in replacement with parts for modifying the lifting height, the chain 9 (removed chain) and the storage container 6 (removed storage container), which have relatively large volumes, are respectively stored in the second storage chamber 52, while the push button cable assembly 15 (removed push button cable assembly) and the temporary chain attachment 18, which have relatively small volumes, are appropriately stored in the empty rooms at the four corners. The temporary chain attachments 17, 18 are jigs used to pass the chain 9 through the main body 101.

[0025] As shown in Figures 6(a) and 6(b), when the main body 101 of the electric chain hoist 100 is placed on the first fixing part 41A and fixed in an orientation extending in a first direction (the left-right direction in Figure 6(b)), the first storage chamber 51 is located to the side of the electric chain hoist 100, so that the upper opening is open without interfering with the main body 101 of the electric chain hoist 100 in plan view. However, as shown in Figures 7(a) and 7(b), when the main body 101 of the electric chain hoist 100 is fixed to the second fixing part 41B, the main body 101 of the electric chain hoist 100 extends in a second direction (the up-down direction in Figure 7(b)), and both ends in the longitudinal direction protrude in the second direction from the hoist machine fixing space 59, so that at least a portion of the first storage chamber 51 overlaps with the main body 101 of the electric chain hoist 100 in plan view.

[0026] 7(a) and 7(b), when the main body 101 of the electric chain hoist 100 is placed on the second fixing part 41B and fixed in an orientation extending in the second direction (the up-down direction in FIG. 7(b)), the second storage chamber 52 is located to the side of the electric chain hoist 100, and therefore the upper opening is open without interfering with the main body 101 of the electric chain hoist 100 in plan view. However, as shown in FIGS. 6(a) and 6(b), when the main body 101 of the electric chain hoist 100 is fixed to the first fixing part 41A, the main body 101 of the electric chain hoist 100 extends in the first direction (the left-right direction in FIG. 6(b)), and both ends in the longitudinal direction protrude in the first direction from the hoist machine fixing space 59, and therefore the second storage chamber 52 at least partially overlaps the main body 101 of the electric chain hoist 100 in plan view.

[0027] -Lifting height modification work- The lifting height modification work using the packing box 30 will be described with reference to FIGS. 6 and 7. FIG.

[0028] First, at the work site, when the packing box 30 containing the parts for lifting height modification is received from a supplier such as a manufacturer, the worker opens the outer box 50 of the packing box 30, removes the storage container 6, chain 9, and push button cable assembly 15 from the main body 101 of the electric chain hoist 100 for which the lifting height is to be modified, and then hangs the main body 101 of the electric chain hoist 100, for example, with a hoist, and places and fixes it on the second fixing part 41B as shown in Fig. 7. Then, the worker places the storage container 6 and chain 9 removed from the main body 101 into the second storage chambers 52 on both sides of the main body 101, and also places the push button cable assembly 15 removed from the main body 101 into one of the empty storage chambers at the four corners (in the example of Fig. 7, the upper right storage chamber in Fig. 7(b)).

[0029] Thereafter, the worker lifts the main body 101 of the electric chain hoist 100, for example, with a hoist, rotates it horizontally (for example, counterclockwise in a plan view) by 90°, and places and fixes it on the first fixing part 41A as shown in Figure 6. Then, the worker removes the storage container 6 and chain 9 for modification and the push button cable set 15 from the first storage chamber 51 or the like, and attaches them to the main body 101 of the electric chain hoist 100.

[0030] After installing or moving the electric chain hoist 100 incorporating the lifting height modification parts to a predetermined location, the worker closes the outer box 50 of the packaging box 30 and returns the removed parts such as the storage container 6 to the supplier.

[0031] -effect- (1) According to this embodiment, the upper part 42 of the packaging box 30 used to package the parts for remodeling the lifting height of the electric chain hoist 100 is provided with a fixing portion 41 that receives and fixes the main body 101 of the electric chain hoist 100. Therefore, when a worker receives the parts for remodeling the lifting height at a work site, the worker can place the main body 101 of the electric chain hoist 100, from which the parts to be replaced with the parts for remodeling the lifting height have been removed, into the unpacked packaging box 30. In this state, the worker can then install the parts for remodeling the lifting height removed from the packaging box 30 into the main body 101 of the electric chain hoist 100. During this operation, the main body 101 of the electric chain hoist 100 placed in the packaging box 30 does not rotate, unlike when the electric chain hoist 100 is suspended by a hoist. This improves the workability of remodeling the lifting height of the electric chain hoist 100. Furthermore, by packing multiple parts for remodeling the lifting height together in the packaging box 30, it is no longer necessary to package the parts for remodeling the lifting height individually, thereby reducing waste. Furthermore, by returning the parts removed from the electric chain hoist 100 to the manufacturer, etc., the removed parts are prevented from being disposed of at the work site, which leads to a reduction in waste and reuse of parts, thereby addressing environmental issues.

[0032] (2) The fixing portion 41 of the packaging box 30 includes a first fixing portion 41A and a second fixing portion 41B, and the main body 101 of the electric chain hoist 100 can be selectively fixed in a position extending in a first direction or in a position extending in a second direction different from the first direction (perpendicular to the first direction in this embodiment). In this case, when the electric chain hoist 100 is placed on the first fixing portion 41A, the opening of the second storage chamber 52 is partially blocked but the first storage chamber 51 is open, and when the electric chain hoist 100 is turned around and placed on the second fixing portion 41B, the opening of the first storage chamber 51 is partially blocked but the second storage chamber 52 is open.

[0033] Therefore, as described above, first, the electric chain hoist 100 is fixed to the second fixing part 41B, and the parts removed from the electric chain hoist 100 are stored in the second storage chamber 52. After that, the electric chain hoist 100 is replaced on the first fixing part 41A, and the lifting height modification parts can be removed from the opened first storage chamber 51.

[0034] In this way, while allowing the electric chain hoist 100 placed on the fixed base 40 to interfere with the first storage chamber 51 and the second storage chamber 52, the first storage chamber 51 and the second storage chamber 52 can be opened when necessary by changing the orientation of the electric chain hoist 100, thereby ensuring the desired workability and preventing the packaging box 30 from becoming larger. Also, the fact that the first storage chamber 51 and the second storage chamber 52 can be selectively opened depending on whether parts removed from the electric chain hoist 100 are to be stored in the packaging box 30 or parts for lifting height modification to be attached to the electric chain hoist 100 are to be removed from the packaging box 30 is advantageous in terms of usability and workability.

[0035] (3) Conventionally, the handling of parts removed from the main body 101 of the electric chain hoist 100 to be replaced with parts for modifying the lifting height has varied from work site to work site. As a result, parts removed from the electric chain hoist 100 have not been managed accurately, and there has been a concern that parts may be incorrectly assembled to the electric chain hoist due to misjudgment at the work site.

[0036] In contrast, in this embodiment, the packaging box 30 is provided with a second storage chamber 52 for storing parts removed from the electric chain hoist 100 when the lifting height is modified using the packaging box 30. In this case, storing the removed parts in the second storage chamber 52 allows them to be organized and managed, and returning the removed parts to the manufacturer or the like can prevent them from being incorrectly assembled at the work site later.

[0037] (4) In this embodiment, the packaging box 30 includes an outer box 50 with a bottom and a fixed base 40 that also serves as a partition that divides the interior of the outer box 50. The fixed base is divided into a lower part 45 that also serves as the partition and an upper part 42 that has a fixed part 41 and is supported by the lower part 45, and the upper part 42 is configured to be detachable from the lower part 45. In this case, it is not necessary to manufacture the entire fixed base 40 according to the size and shape of the electric chain hoist 100 whose lifting height is to be modified. By manufacturing only the upper part 42 according to the electric chain hoist 100, electric chain hoists 100 of different sizes and shapes can be fixed.

[0038] (5) In the packaging box 30 of this embodiment, the fixing portion 41 for fixing the electric chain hoist 100 is simply a recessed portion recessed downward and provided on the upper surface of the upper portion 42 of the fixing base 40. Therefore, the fixing portion 41 can be formed by a simple process, and an increase in the cost of the packaging box 30 can be suppressed.

[0039] (6) Contributing to decarbonization by forming the packaging box 30, including the fixing base 40 and the outer box 50, from recyclable materials. In addition, by manufacturing the packaging box 30 from materials strong enough for repeated use, the packaging box 30 can be reused.

[0040] -Additional remarks- The present invention is not limited to the above-described embodiments and may include various modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations. For example, it is possible to replace some of the configurations with other configurations. It is also possible to delete some of the configurations of the embodiments or add other configurations.

[0041] For example, in the above embodiment, the fixing portion 41 provided on the packaging box 30 is a recess formed to accommodate a single electric chain hoist 100. However, the same fixing portion 41 may be made more versatile so that it can fix multiple electric chain hoists 100 of different sizes or shapes. For example, as shown in FIG. 8( a), the fixing portion 41 may be formed as a stepped recess having an upper section 41a and a lower section 41b, in which a relatively large electric chain hoist 100 is supported by the upper section 41a and a relatively small electric chain hoist 100 is supported by the lower section 41b. Alternatively, as shown in FIG. 8( b), a removable spacer 41c may be used to change the size and shape of the fixing portion 41. Furthermore, the fixing portion 41 is not limited to a recess. As shown in FIG. 8( c), the fixing portion 41 may have multiple protrusions 41d protruding upward from the top surface of the upper section 42 of the fixing base 40, and the electric chain hoist 100 may be fixed between these protrusions 41d. Figure 8(c) illustrates a configuration in which the protrusion 41d can be attached and detached to the upper part 42 of the fixed base 40 by means of a fitting structure, but the upper part 42 of the fixed base 40 and the protrusion 41d may be formed integrally, for example, by processing the upper part 42 of the fixed base 40 into the shape illustrated in Figure 8(c).

[0042] Furthermore, the hoist whose lifting height is modified using the packaging box 30 is not limited to the electric chain hoist 100. For example, the packaging box 30 can also be applied when modifying the lifting height of other types of hoists, such as chain hoists that are hoisted and lowered manually without using power such as electricity.
