Summary of the Invention

Problems to be Solved by the Invention

[0004] The present disclosure discloses an example of a storage rack in which the storage performance of an object and the workability during the transfer operation are taken into consideration.

Means for Solving the Problems

[0005] A storage rack for placing and storing an object includes, for example, a mounting table (2) that contacts the lower surface of the object and on which the object is placed, the mounting table (2) being swingable, and a rear surface support portion (3) that supports the rear surface side of the object placed on the mounting table (2). It is desirable to provide.

[0006] The swing center axis (Lo) is preferably set on the front side of the center in the depth direction of the mounting table (2) and is parallel to the direction orthogonal to the depth direction. The side opposite to the rear side with respect to the swing center axis (Lo) of the mounting table (2) is the front side, and the direction parallel to the direction from the front side toward the rear side is defined as the depth direction.

[0007] As a result, when an object is placed on the mounting platform (2), the platform (2) tilts so that its rear side is lower than its front side. Therefore, the object placed on the mounting platform (2) is stored tilted to the rear side with its upper side in contact with the rear support (3). Consequently, the object placed on it becomes stable, improving its storage efficiency.

[0008] When transferring an object placed on the mounting platform (2) to a trolley, tilting the object forward will cause the mounting platform (2) to rotate accordingly, with the front side lowering and the back side rising. Therefore, it becomes possible to easily transfer an object placed on the mounting platform (2) to a trolley. In other words, this storage rack improves both the storage efficiency of the objects and the work efficiency during the transfer process.

[0009] The storage rack may also have the following configuration, for example: In other words, it is desirable that the mounting platform (2) is provided with an elongated hole (2A) that extends in the depth direction from the front end of the mounting platform (2) and penetrates the mounting platform (2) in the vertical direction. This makes it possible to easily transfer the object to a trolley operated by a manual forklift system.

[0010] In other words, the worker can place the object on the forks of the trolley by placing the forks through the elongated holes (2A) against the underside of the object. Then, while the object is still on the forks, the worker can easily transfer the object to the trolley by tilting the trolley towards them.

[0011] Furthermore, it is desirable to provide an auxiliary bar (4) that can contact the upper back of the object placed on the mounting platform (2), and that can be moved to the front by the operator's operation to tilt the object toward the front. This allows the operator to easily tilt the object toward the front, thereby improving work efficiency during the object replacement operation.

[0012] Furthermore, it is desirable that a weight (2B) is provided on the mounting platform (2) on the front side of the pivot axis (Lo) to rotate the mounting platform (2) so that the front side of the mounting platform (2) is lower than the rear side. As a result, when no object is placed on the mounting platform (2), the mounting surface (2C) is tilted so that the front side is lower, improving the workability when placing an object on the mounting platform (2).

[0013] Furthermore, it is desirable that the mounting surface (2C) be provided with rollers (2D) that assist in the sliding displacement of the mounted object in the depth direction. This makes it possible to easily slide the object to the rear when placing it on the mounting base (2), and to easily slide the object to the front during replacement work.

Mode for Carrying Out the Invention

[0016] The following "Embodiments of the Invention" show an example of embodiments belonging to the technical scope of the present disclosure. That is, the invention-specific matters described in the claims are not limited to the specific configurations, structures, etc. shown in the following embodiments.

[0017] In this embodiment, an example is shown in which the storage rack according to the present disclosure is applied to a storage rack having an object to be stored (also referred to as a "raw fabric") in which a fabric for the surface of a sheet or the like is wound in a roll shape. That is, the storage rack according to this embodiment is a storage rack for placing and storing the raw fabric as the object.

[0018] Note that the arrows indicating the directions attached to each figure are described to facilitate understanding of the relationship between the figures and the shape of the members or parts. Therefore, the storage rack is not limited to the directions attached to each figure.

[0019] At least one member or part described with a reference sign is provided at least one, unless otherwise noted such as "one". The storage rack shown in the present disclosure includes at least one of the components such as the members or parts described with a reference sign and the structural parts shown in the drawings.

[0020] (First Embodiment) <1. Outline of the storage rack> The storage rack 1 according to the present embodiment shown in FIG. 1 is a rack for storing the object OB in a state where the longitudinal direction (roll central axis) of the object OB intersects with the horizontal plane. The storage rack 1 includes at least a mounting table 2 and a rear support portion 3 or the like.

[0021] <Mounting table> The mounting platform 2 is a raw material storage area on which the object OB is placed, and which contacts the lower surface of the object OB. The mounting platform 2 is pivotable between the position shown by the solid line and the position shown by the dashed line in Figure 1.

[0022] As shown in Figure 2, the pivot axis Lo of the mounting platform 2 is set on the front side of the center in the depth direction of the mounting platform 2, and is parallel to the horizontal direction perpendicular to the depth direction. The depth direction refers to the direction parallel to the direction from the front side to the back side. The front side refers to the side opposite the back side with respect to the pivot axis Lo.

[0023] Furthermore, the mounting base 2 is provided with at least one (two in this embodiment) elongated holes 2A. These elongated holes 2A are elongated holes that extend from the front end of the mounting base 2 to the rear side in the depth direction, and are composed of through holes that penetrate the mounting base 2 in the vertical direction.

[0024] Incidentally, the mounting base 2 according to this embodiment is composed of three independent small mounting bases 21 to 23. These small mounting bases 21 to 23 are arranged along the pivoting center axis Lo with a predetermined gap between them.

[0025] The gap between two adjacent small mounting platforms constitutes the elongated hole 2A. Furthermore, each of the three small mounting platforms 21-23 in this embodiment is independently pivotable. In other words, each of the three small mounting platforms 21-23 is capable of different pivoting movements.

[0026] As shown in Figure 1, a weight portion 2B is provided on the lower surface of the mounting base 2 (in this embodiment, three small mounting bases 21-23) on the front side of the pivot axis Lo. The weight portion 2B generates a rotational force such that the front side of the mounting base 2 becomes lower than the rear side.

[0027] In other words, when the object OB is not placed on the mounting base 2, the mounting base 2 is tilted so that the front side is lower, as shown by the dashed line in Figure 1, due to the gravity acting on the weight portion 2B.

[0028] Furthermore, as shown in Figure 2, multiple rollers 2D are provided on the mounting surface 2C, that is, the upper surface of each small mounting platform 21-23. The multiple rollers 2D are cylindrical or spherical rollers arranged so that their rotational axis is parallel to the oscillation axis Lo. In this way, the multiple rollers 2D assist in the sliding displacement of the object OB placed on the mounting platform 2 in the depth direction.

[0029] As shown in Figure 1, the rear support portion 3 is a member that supports the rear side of the object OB placed on the mounting base 2. In other words, the pivot axis Lo of the mounting base 2 is set to the front side of the center in the depth direction of the mounting base 2.

[0030] Therefore, when the object OB is positioned on the rear side of the pivot axis Lo on the mounting surface 2C, the upper end of the object OB tilts to the rear side. The rear support part 3 then supports the upper end of the object OB that has tilted to the rear side.

[0031] <Support bar> The storage rack 1 according to this embodiment also includes an auxiliary bar 4, as shown in Figure 1. The auxiliary bar 4 is a member that can contact the upper rear surface of the object OB placed on the mounting base 2. The auxiliary bar 4 is a member that can be moved to the front side by the operator's operation to tilt the object OB toward the front.

[0032] Specifically, the auxiliary bar 4 is connected to the slider 41, as shown in Figure 2. The slider 41 is a block material that can slide in the depth direction. The slider 41 is slidably supported by the guide pipe 42 that constitutes the guide rail.

[0033] As shown in Figure 1, an operating handle 43 is connected to the slider 41. The operating handle 43 is an operating part that is operated by the operator. A spring 44 is positioned on the front side of the guide pipe 42.

[0034] The spring 44 compresses and deforms when the slider 41 is displaced to the front, exerting an elastic force that pushes the slider 41 back to the rear. Permanent magnets 45A and 45B are placed on the rear side of the auxiliary bar 4 and on the rear rack frame 11.

[0035] Therefore, when the auxiliary bar 4 approaches the rear rack frame 11, the magnetic attraction between the permanent magnet 45A provided on the auxiliary bar 4 and the permanent magnet 45B provided on the rear rack frame 11 holds the position of the auxiliary bar 4 toward the rear rack frame 11.

[0036] <2. Trolley> The trolley 10 shown in Figure 3 is a trolley used when loading and unloading objects OB into and from the storage rack 1 according to this embodiment. The trolley 10 is equipped with at least a scooping plate 11, main wheels 12 and auxiliary wheels 13, etc.

[0037] The sheet metal 11 is a fork-shaped part that supports the lower end of the object OB. Specifically, the sheet metal 11 is a strip-shaped member that can be fitted into the elongated hole 2A so as to pass through the elongated hole 2A.

[0038] The auxiliary wheels 13 are wheels that work in cooperation with the main wheels 12 to support the bogie body 10A when the bogie 10 is tilted around the main wheels 12 (as shown by the solid line in Figure 3). Incidentally, when the auxiliary wheels 13 are lifted off the floor (as shown by the dashed line in Figure 3), the bogie body 10A is supported only by the main wheels 12.

[0039] The trolley body 10A is provided with multiple guides 14. Each guide 14 holds the object OB on its side and the worker's side (the left side of the object OB in Figure 3), preventing the object OB from falling over.

[0040] <3. Method of use of the storage rack according to this embodiment and its features> <3.1 When transferring an object from a storage rack to a trolley> First, the worker positions the sheet metal 11 so that it is inserted into the corresponding position in the elongated hole 2A, as shown in Figure 4. Next, the worker tilts the trolley body 10A around the main wheel 12 until the auxiliary wheel 13 touches the floor, as shown in Figure 5.

[0041] As a result, the forming plate 11 passes through the elongated hole 2A and comes into contact with the lower surface of the object OB, as shown in Figure 6, so that the worker can form (scoop up) the object OB with the forming plate 11.

[0042] Furthermore, in the above operation, it is desirable for the operator to pull the operating handle 43 toward the front. That is, when the operating handle 43 is pulled toward the front, the upper rear side of the object OB is pressed toward the front by the auxiliary bar 4.

[0043] Therefore, as shown in Figure 6, the object OB moves from the rear side to the front side. When the center of gravity of the object OB moves to the front side of the pivot axis Lo, the mounting platform 2 tilts so that the front side is lower than the rear side (see Figure 5).

[0044] At this time, the object OB on the mounting platform 2 moves towards the front side of the mounting platform 2, that is, towards the trolley body 10A, by sliding on the mounting surface 2C due to the rotation of the multiple rollers 2D, as shown in Figure 7.

[0045] This completes the transfer of the object OB, which is placed on the mounting platform 2, to the trolley 10. Since the mounting platform 2 is equipped with a weight 2B, once the transfer of the object OB is complete, the mounting platform 2 is held in a tilted position such that the front side is lower than the back side.

[0046] Incidentally, when the operating handle 43 is pulled towards the front, the spring 44 is compressed and deformed. Therefore, when the force required to pull the operating handle 43 is lost, the auxiliary bar 4 is pushed back to the rear by the elastic force of the spring 44 (see Figures 8A and 8B).

[0047] The auxiliary bar 4, which has been pushed back to the rear side, is held in place by the magnetic attraction of the permanent magnets 45A and 45B, in the position on the rear rack frame 11 side. Therefore, the worker does not need to manually return the auxiliary bar 4 to the rear side.

[0048] As described above, in the transfer operation to the trolley 10 using the storage rack 1, the object OB can be transferred to the trolley 10 by sliding it by utilizing the fact that the mounting platform 2 tilts forward (towards the trolley 10). Therefore, even heavy objects OB can be easily transferred to the trolley 10.

[0049] In other words, when transferring an object OB placed on the mounting platform 2 to the trolley 10, tilting the object OB towards the front will cause the mounting platform 2 to rotate accordingly, with the front side lowering and the back side rising. Therefore, it becomes possible to easily transfer an object placed on the mounting platform 2 to the trolley.

[0050] Furthermore, since the storage rack 1 is equipped with an auxiliary bar 4, the worker can easily tilt the object OB towards the front. Consequently, the work efficiency during the replacement of the object OB is improved. Furthermore, in the storage rack 1, the elastic force of the compressed and deformed spring 44 is used to return the auxiliary bar 4 to the rear side. As a result, the operating force required to pull the operating handle 43 to the front side is reduced compared to, for example, a configuration in which a tension spring for return is connected to the auxiliary bar 4.

[0051] In other words, in a configuration using a tension spring, when the operating handle 43 is pulled to the front, the elastic force of the spring always acts on the slider 41. In contrast, in this embodiment, the elastic force of the spring 44 does not act on the slider 41 until the slider 41 comes into contact with the spring 44. Therefore, the operating force required to pull the operating handle 43 to the front is reduced.

[0052] <3.2 When transferring an object from a trolley to a storage rack> The process of transferring the object OB from the trolley 10 to the storage rack 1 is the reverse of the process of transferring the object OB from the storage rack 1 to the trolley 10. In other words, the worker raises the trolley 10 on which the object OB is placed so that the sheet metal 11 passes through the elongated hole 2A from top to bottom.

[0053] As a result, the object OB is placed on the mounting platform 2. When the object OB is placed on the mounting platform 2, the mounting platform 2 tilts so that its rear side is lower than its front side (see Figure 9).

[0054] Therefore, the object OB placed on the mounting base 2 is stored tilted towards the rear with its upper side in contact with the rear support part 3. Consequently, the object OB is stable, improving the storage efficiency of the object. As described above, the storage rack 1 improves both the storage efficiency of the object OB and the work efficiency during the transfer operation.

[0055] (Other embodiments) In the embodiments described above, permanent magnets 45A and 45B were arranged on the rear side of the auxiliary bar 4 and on the rear rack frame 11. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which the auxiliary bar 4 is eliminated, or a configuration in which permanent magnets are arranged on one of the rear side of the auxiliary bar 4 and the rear rack frame 11, and a ferromagnetic material is arranged on the other.

[0056] In the embodiments described above, one mounting platform 2 was composed of multiple small mounting platforms 21-23. However, the disclosure is not limited thereto. That is, the disclosure may, for example, consist of one large mounting platform 2.

[0057] In the above-described embodiment, a weight portion 2B was provided on the mounting base 2. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which the weight portion 2B is eliminated, or a configuration in which a spring is provided in place of the weight portion 2B. The spring is an elastic spring that rotates the mounting base 2 so that the front side of the mounting base 2 becomes lower.

[0058] In the above-described embodiment, a roller 2D was provided on the mounting surface 2C. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which spherical rolling elements are provided, or a configuration in which a sliding plate with a low coefficient of friction is arranged.
