Description

Technical Field

[0001] This disclosure pertains to the field of material handling, specifically relating to a material turnover system and a material storage vehicle. Background Technology

[0002] It is known that during the assembly of an electrical cabinet, materials such as components, wires, cables, and cable trays need to be transported from one or more storage locations to the assembly location. Typically, these materials are contained in turnover boxes during transport, and the turnover boxes are moved between the storage locations (if multiple storage locations exist) and between the storage locations and the assembly location by means of transport vehicles (e.g., hydraulic carts or handcarts).

[0003] However, the materials are stacked together in the turnover boxes and can only be accessed through the opening at the top, making material retrieval inconvenient. Furthermore, the mixing of different types of materials in the turnover boxes makes them prone to loss, resulting in unnecessary material waste. Additionally, because the turnover boxes need to be combined with the transport vehicles, a series of preparatory work must be completed before transportation begins (e.g., allocating the transport vehicles, placing the turnover boxes on the vehicles), which reduces the material turnover efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this disclosure provides a material turnover system comprising: a material storage cart including a storage frame defining a storage space for accommodating materials, the storage space being provided with a mesh wall for holding the materials within the storage space; a first turnover cart configured to move between the material storage cart and a target location, the first turnover cart including a first turnover frame defining a turnover space for accommodating the materials, the sides of the turnover space being at least partially open; and a second turnover cart configured to move between the material storage cart and the target location, the second turnover cart including a second turnover frame and a support arm extending outwardly from the second turnover frame for suspending the materials.

[0005] In this disclosure, by incorporating a mesh wall, the material handling system can improve turnover efficiency by providing open sections for viewing the material while preventing loss, allowing for accurate material selection. Furthermore, the mesh wall requires less material, resulting in a lighter material storage cart that is easier to deploy and a lower manufacturing cost for the material handling system. By making the sides of the turnover space at least partially open, materials can be smoothly accessed even when stacked, further improving turnover efficiency. The support arms neatly hold slender, flexible components on the second turnover cart, facilitating material retrieval and improving turnover efficiency. By providing material storage carts, the storage space can be flexibly deployed according to target locations, thereby enhancing turnover efficiency. By providing a first turnover vehicle with integrated turnover space and a second turnover vehicle with integrated outriggers, the material turnover system can eliminate the process of combining turnover boxes and handling vehicles, thereby improving turnover efficiency. In addition, the first and second turnover vehicles can transport slender, flexible materials separately from other types of materials, preventing slender, flexible materials from knotting or getting entangled with other types of materials, thus improving turnover efficiency.

[0006] Furthermore, the storage frame includes a main storage frame; the storage space includes a first storage space located in the main storage frame, and a door is provided on the side of the first storage space, the door being configured to move between an open position that allows material access and a closed position that prevents material access.

[0007] In this disclosure, by providing a door on the side of the first storage space, even if materials are stacked together, the materials in the first storage space can be smoothly taken out when the door is in the open position, thereby improving turnover efficiency.

[0008] Furthermore, the storage frame also includes a secondary storage frame disposed on the side surface of the main storage frame; the storage space also includes a second storage space located in the secondary storage frame, the top of the second storage space being at least partially open.

[0009] In this disclosure, by making the top of the second storage space at least partially open, the second storage space allows material to protrude from the top of the second storage space when accommodating slender rigid material, making the second storage space suitable for storing slender rigid material, thereby expanding the application scenarios of the material turnover system.

[0010] Furthermore, the side surface of the main storage frame includes a first side surface oriented in the lateral direction and a second side surface oriented in the longitudinal direction; the material storage vehicle also includes a first handle, the first handle and the sub-storage frame are disposed on the first side surface, the first handle is located above the sub-storage frame, and a first gap is formed between the first handle and the first side surface; the material storage vehicle also includes a second handle, the second handle is disposed on the second side surface, and a second gap is formed between the second handle and the second side surface.

[0011] In this disclosure, by providing a first handle and a second handle, the user can move the material storage cart using the first handle and / or the second handle, making the material storage cart easy to operate. By forming a first gap and a second gap, the user can grasp the first handle and the second handle by passing their fingers through the first gap and the second gap, making the material storage cart even easier to operate; furthermore, since the first gap and the second gap are defined by the first handle and the second handle together with the storage frame, the first handle and the second handle do not need to have a complex gripping structure, allowing the material storage cart to have a simple and compact structure. By placing the first handle above the secondary storage frame, slender rigid materials in the second storage space can pass through the first gap, allowing the first handle to limit the slender rigid materials, thereby preventing the slender rigid materials from tilting excessively or even falling out of the second storage space. By placing the secondary storage frame and the second handle on the first side surface and the second side surface respectively, even if slender rigid materials are stored in the second storage space, the slender rigid materials will not pass through the second gap, so that the second handle can still be gripped.

[0012] Furthermore, the storage space is provided with a mesh wall on its side.

[0013] In this disclosure, by setting the mesh wall on the side of the storage space, the materials in the storage space are easily observed, especially the materials stacked together, thereby improving turnover efficiency.

[0014] Furthermore, the turnover space is open on opposite sides oriented in the longitudinal direction; and / or the turnover space is open on opposite sides oriented in the transverse direction.

[0015] In this disclosure, by opening the sides of the turnover space oriented in opposite directions along the longitudinal direction and / or opening the sides of the turnover space oriented in opposite directions along the transverse direction, when the first turnover vehicle transports slender rigid materials, the slender rigid materials can pass through the turnover space through the open sides of the turnover space, so that the center of gravity of the slender rigid materials can be adjusted to a suitable position, thereby enabling the slender rigid materials to be stably held on the first turnover vehicle.

[0016] Furthermore, the second turnover frame includes a base extending in a longitudinal direction; the support arm includes a first support arm and a second support arm, the first support arm extending from the base in a transverse direction toward a first side, a plurality of the first support arms being arranged side by side in the longitudinal direction, and the second support arm extending from the base in a transverse direction toward a second side opposite to the first side, a plurality of the second support arms being arranged side by side in the longitudinal direction.

[0017] In this disclosure, by setting a base, a first arm, and a second arm, multiple arms can be at the same height, making it easy to access materials suspended on these arms, thereby improving turnover efficiency.

[0018] Furthermore, the plurality of bases are arranged side by side in the vertical direction, and each base is provided with the first arm and the second arm.

[0019] In this disclosure, by arranging multiple bases side by side in the vertical direction, the second turnover car can have more arms within a certain length and width dimensions, thereby improving the conveying capacity of the second turnover car.

[0020] Furthermore, the second turnover vehicle also includes a storage box with an open top; the storage box is supported on the second turnover frame, and the support arm is located above the storage box.

[0021] In this disclosure, by providing a storage box, materials unsuitable for hanging on the support arm can be accommodated, such as materials that are too long or too short, or unopened materials, thus making the second turnover cart widely applicable. By positioning the support arm above the storage box, the storage box can collect materials that fall from the support arm, such as materials that fall from the support arm due to vibration, thereby reducing material loss.

[0022] Furthermore, the second turnover cart also includes a workbench supported on the second turnover frame, with the support arm located above the workbench; the workbench includes an extension portion, the projection of the extension portion in the vertical direction being offset from the projection of the support arm in the vertical direction.

[0023] In this disclosure, by setting up a workbench, the user can process materials on the workbench, such as connecting terminals to wires, thus enabling the second turnover cart to have multiple uses. This arrangement is particularly advantageous in situations with limited workspace or harsh working conditions. By positioning the support arm above the workbench, the workbench can collect materials that fall from the support arm, such as materials that fall due to vibration, thereby reducing material loss. By providing an extension section, when the support arm and workbench are positioned close together, the user is less likely to be disturbed by the support arm when using the workbench, thereby improving user comfort and material handling efficiency.

[0024] This disclosure also provides a material storage vehicle including a storage frame defining a storage space for accommodating materials, the storage space being provided with a mesh wall for holding the materials within the storage space; the storage frame including a main storage frame, the storage space including a first storage space located within the main storage frame, the first storage space having a door on its side configured to move between an open position allowing material access and a closed position preventing material access; the storage frame further including a secondary storage frame disposed on a side surface of the main storage frame, the storage space further including a second storage space located within the secondary storage frame, the top of the second storage space being at least partially open.

[0025] Furthermore, the side surface of the main storage frame includes a first side surface oriented in the lateral direction and a second side surface oriented in the longitudinal direction; the material storage vehicle also includes a first handle, the first handle and the sub-storage frame are disposed on the first side surface, the first handle is located above the sub-storage frame, and a first gap is formed between the first handle and the first side surface; the material storage vehicle also includes a second handle, the second handle is disposed on the second side surface, and a second gap is formed between the second handle and the second side surface.

[0026] Furthermore, the storage space is provided with a mesh wall on its side. Attached Figure Description

[0074] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0075] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0076] The following is for reference. Figures 1 to 10 A material turnover system according to a first embodiment of the present disclosure is described.

[0077] refer to Figures 1 to 10 The material handling system includes a material storage cart 1, a first turnover cart 2, and a second turnover cart 3. The material storage cart 1 includes a storage frame 11 defining a storage space 12 for receiving materials. The storage space 12 is provided with a mesh wall (not shown) for holding materials within the storage space 12. The first turnover cart 2 is configured to move between the material storage cart 1 and a target location. The first turnover cart 2 includes a first turnover frame 21 defining a turnover space 22 for receiving materials. The sides of the turnover space 22 are at least partially open. The second turnover cart 3 is configured to move between the material storage cart 1 and the target location. The second turnover cart 3 includes a second turnover frame 31 and outwardly extending support arms 32 for suspending materials.

[0078] In this disclosure, "open" means that materials can be freely accessed through the open portion. Furthermore, unless otherwise specified, the longitudinal direction L, the transverse direction T, and the vertical direction V are orthogonal to each other, and these directions are not used to restrict the direction of travel of the vehicle.

[0079] As an example, the materials can be those required for assembling the electrical cabinet, such as components, wires, cables, cable trays, etc. Correspondingly, the target location can be the location for assembling the electrical cabinet.

[0080] As an example, the second turnover car 3 can be used to transport slender, flexible materials, such as wires and cables. The first turnover car 2 can be used to transport materials other than slender, flexible materials, such as components and cable trays.

[0081] As an example, the mesh wall can be a metal mesh, for instance, it can be woven from metal wires.

[0082] In this disclosure, by providing a mesh wall, the material storage cart 1 can prevent material loss while offering a perforated section for viewing the material, allowing for accurate material selection and thus improving the turnover efficiency of the material handling system. Furthermore, the mesh wall requires less material, resulting in a lighter material storage cart 1, making it easier to deploy and reducing the manufacturing cost of the material handling system. By making the sides of the turnover space 22 at least partially open, materials can still be smoothly stored and retrieved even when stacked, thereby improving turnover efficiency. The support arm 32 neatly holds the slender, flexible components on the second turnover cart 3, making materials easy to access and further improving turnover efficiency. By providing the material storage cart 1, the storage space 12 can be flexibly deployed according to the target location, thereby improving turnover efficiency. By providing a first turnover cart 2 with integrated turnover space 22 and a second turnover cart 3 with integrated support arm 32, the material turnover system can eliminate the process of combining turnover boxes and handling vehicles, thereby improving turnover efficiency. In addition, the first turnover cart 2 and the second turnover cart 3 can transport slender flexible materials separately from other types of materials, so that slender flexible materials will not tangle or become entangled with other types of materials, thereby improving turnover efficiency.

[0083] refer to Figures 1 to 4 The storage frame 11 includes a main storage frame 11a. The storage space 12 includes a first storage space 121 located in the main storage frame 11a. A door 13 is provided on the side of the first storage space 121, and the door 13 is configured to move between an open position that allows material access and a closed position that prevents material access.

[0084] As an example, the main storage frame 11a can define multiple first storage spaces 121. For instance, the multiple first storage spaces 121 can be arranged side by side in the vertical direction V, and adjacent first storage spaces 121 can share a common mesh wall. In other words, adjacent first storage spaces 121 can be separated by a mesh wall.

[0085] As an example, the door 13 can be pivotally connected to the main storage frame 11a. For instance, the material storage cart 1 may include a hinge 16, through which the door 13 can be pivotally connected to the main storage frame 11a. The pivot axis of the door 13 can extend in the longitudinal direction L, allowing the door 13 to be tilted upwards or downwards.

[0086] In this disclosure, by providing a door 13 on the side of the first storage space 121, even if materials are stacked together, the materials in the first storage space 121 can be smoothly taken out when the door 13 is in the open position, thereby improving turnover efficiency.

[0087] refer to Figures 1 to 4 The storage frame 11 also includes a secondary storage frame 11b, which is disposed on the side surface of the main storage frame 11a. The storage space 12 also includes a second storage space 122 located in the secondary storage frame 11b, the top of which is at least partially open.

[0088] As an example, the secondary storage frame 11b can be disposed on the side surface of the primary storage frame 11a oriented in the lateral direction T. For example, the primary storage frame 11a and the secondary storage frame 11b can have approximately the same dimensions in the longitudinal direction L and the vertical direction V.

[0089] As an example, the secondary storage frame 11b can be disposed at the bottom of the side surface of the main storage frame 11a. For example, the secondary storage frame 11b can be arranged side by side with the lowermost first storage space among a plurality of first storage spaces 121 in the lateral direction T.

[0090] As an example, a shared mesh wall may exist between the second storage space 122 and the first storage space 121.

[0091] In this disclosure, by making the top of the second storage space 122 at least partially open, the second storage space 122 allows material to protrude from the top of the second storage space 122 when accommodating elongated rigid material, making the second storage space 122 suitable for storing elongated rigid material (e.g., a trough), thereby expanding the application scenarios of the material turnover system.

[0092] refer to Figures 1 to 4 The main storage frame 11a has a side surface including a first side surface 11c oriented in the transverse direction T and a second side surface 11d oriented in the longitudinal direction L. The material storage cart 1 also includes a first handle 14. The first handle 14 and the auxiliary storage frame 11b are disposed on the first side surface 11c, with the first handle 14 located above the auxiliary storage frame 11b. A first gap 141 is formed between the first handle 14 and the first side surface 11c. The material storage cart 1 also includes a second handle 15. The second handle 15 is disposed on the second side surface 11d. A second gap 151 is formed between the second handle 15 and the second side surface 11d.

[0093] As an example, the first handle 14 and the second handle 15 may have a generally U-shaped shape. For example, the first handle 14 and the second handle 15 may extend in a plane perpendicular to the vertical direction V, and the two ends of the first handle 14 and the two ends of the second handle 15 may be respectively engaged with the first side surface 11c and the second side surface 11d.

[0094] As an example, the first handle 14 and the main storage frame 11a may have approximately the same dimensions in the longitudinal direction L, and the second handle 15 and the main storage frame 11a may have approximately the same dimensions in the transverse direction T.

[0095] As an example, the projection of the first gap 141 in the vertical direction V coincides with the projection of the top of the second storage space 122 in the vertical direction V. For example, the projection of the first gap 141 in the vertical direction V may lie entirely within the projection of the top of the second storage space 122 in the vertical direction V.

[0096] In this disclosure, by providing a first handle 14 and a second handle 15, the user can move the material storage cart 1 using the first handle 14 and / or the second handle 15, making the material storage cart 1 easy to operate. By forming a first gap 141 and a second gap 151, the user can grasp the first handle 14 and the second handle 15 by passing their fingers through the first gap 141 and the second gap 151, making the material storage cart 1 even easier to operate; furthermore, since the first gap 141 and the second gap 151 are defined by the first handle 14 and the second handle 15 together with the storage frame 11, the first handle 14 and the second handle 15 do not need to be provided with a complex gripping structure, allowing the material storage cart 1 to have a simple and compact structure. By positioning the first handle 14 above the secondary storage frame 11b, slender rigid materials in the second storage space 122 can pass through the first gap 141, allowing the first handle 14 to limit the slender rigid materials, thereby preventing the slender rigid materials from tilting excessively or even falling out of the second storage space 122. By setting the secondary storage frame 11b and the second handle 15 on the first side surface 11c and the second side surface 11d respectively, even if a slender rigid material is stored in the second storage space 122, the slender rigid material will not pass through the second gap 151, so that the second handle 15 can still be held.

[0097] refer to Figures 1 to 4 The storage space 12 has a mesh wall on its side.

[0098] As an example, mesh walls can be provided on the sides of the first storage space 121 and the sides of the second storage space 122. For example, mesh walls can be provided on the top, bottom, and sides of the first storage space 121, and mesh walls can be provided on the bottom and sides of the second storage space 122.

[0099] As an example, the door body 13 can be provided with a mesh wall.

[0100] In this disclosure, by setting the mesh wall on the side of the storage space 12, the materials in the storage space 12 are easily observed, especially the materials stacked together, thereby improving turnover efficiency.

[0101] The material storage vehicle 1 also includes a storage board (not shown), which is detachably attached to the storage frame 11.

[0102] As an example, the storage board can be detachably attached to the main storage frame 11a, for example, to the side surface of the main storage frame 11a oriented in the longitudinal direction L.

[0103] refer to Figures 5 to 7 The turnover space 22 is open on the sides oriented in opposite directions along the longitudinal direction L; and / or the turnover space 22 is open on the sides oriented in opposite directions along the transverse direction T.

[0104] As an example, the first turnover cart 2 may include multiple turnover spaces 22. For instance, the multiple turnover spaces 22 may be arranged side by side in the vertical direction V. In this case, the first turnover cart 2 may also include partitions 23 for separating adjacent turnover spaces 22. When the first turnover cart 2 transports materials, the partitions 23 can hold the materials.

[0105] As an example, the sides of the turnover space 22, oriented in opposite directions along the longitudinal direction L and in opposite directions along the transverse direction T, are both open.

[0106] In this disclosure, by opening the sides of the turnover space 22 oriented in opposite directions along the longitudinal direction L and / or opening the sides of the turnover space 22 oriented in opposite directions along the transverse direction T, when the first turnover vehicle 2 transports slender rigid materials, the slender rigid materials can pass through the turnover space 22 through the open sides of the turnover space 22, so that the center of gravity of the slender rigid materials can be adjusted to a suitable position, thereby enabling the slender rigid materials to be stably held on the first turnover vehicle 2.

[0107] The first turnover vehicle 2 also includes a first turnover signboard (not shown), which is detachably attached to the first turnover frame 21.

[0108] As an example, the first turnover board can be attached to the side surface of the first turnover frame 21 oriented in the longitudinal direction L.

[0109] refer to Figures 8 to 10The second turnover frame 31 includes a base 311 extending in the longitudinal direction L. The support arm 32 includes a first support arm 321 and a second support arm 322. The first support arm 321 extends from the base 311 in the transverse direction T toward a first side, and a plurality of first support arms 321 are arranged side-by-side in the longitudinal direction L. The second support arm 322 extends from the base 311 in the transverse direction T toward a second side opposite to the first side, and a plurality of second support arms 322 are arranged side-by-side in the longitudinal direction L.

[0110] As an example, the extension direction of the outrigger 32 can be parallel to the lateral direction T. In other examples, the extension direction of the outrigger 32 can form an angle with the lateral direction T.

[0111] As an example, a first arm 321 and a second arm 322 may extend from the same portion of the base 311.

[0112] In this disclosure, by setting a base 311, a first support arm 321 and a second support arm 322, multiple support arms 32 can be at the same height, making it easy to access materials suspended on these support arms 32, thereby improving turnover efficiency.

[0113] refer to Figures 8 to 10 Multiple bases 311 are arranged side by side in the vertical direction V, and each base 311 is provided with a first arm 321 and a second arm 322.

[0114] In this disclosure, by arranging multiple bases 311 side by side in the vertical direction V, the second turnover car 3 can have more support arms 32 within a certain length and width dimensions, thereby improving the conveying capacity of the second turnover car 3.

[0115] refer to Figures 8 to 10 The second turnover cart 3 also includes a storage box 33 with an open top. The storage box 33 is supported on the second turnover frame 31, and the support arm 32 is located above the storage box 33.

[0116] As an example, storage box 33 can be made of wood.

[0117] As an example, the storage box 33 can be detachably supported on the second turnover frame 31.

[0118] In this disclosure, by providing a storage box 33, the storage box 33 can be used to hold materials that are not suitable for hanging on the support arm 32, such as materials that are too long or too short, or materials that are not yet opened, thus making the second turnover cart 3 widely applicable. By positioning the support arm 32 above the storage box 33, the storage box 33 can collect materials that fall from the support arm 32, such as materials that fall from the support arm 32 due to vibration, thereby reducing material loss.

[0119] The second turnover vehicle 3 also includes a second turnover signboard (not shown), which is detachably attached to the second turnover frame 31.

[0120] As an example, the second turnover board can be attached to the side surface of the second turnover frame 31 oriented in the longitudinal direction L.

[0121] The following is for reference. Figures 11 to 13 A material turnover system according to a second embodiment of the present invention is described. The second embodiment is a variation of the first embodiment, and the same reference numerals are used in this embodiment for features that are the same as or similar to those in the first embodiment, and detailed descriptions of these features are omitted.

[0122] refer to Figures 11 to 13 The second turnover cart 3 also includes a worktable 34. The worktable 34 is supported on the second turnover frame 31, and the support arm 32 is located above the worktable 34. The worktable 34 includes an extension portion 341, the projection of the extension portion 341 in the vertical direction V being offset from the projection of the support arm 32 in the vertical direction V.

[0123] Here, one projection being offset from another means that the two projections have no overlapping parts; otherwise, the two projections would overlap.

[0124] As an example, the worktable 34 can be plate-shaped and perpendicular to the vertical direction V.

[0125] As an example, the second turnover cart 3 may also include a support element 35. The support element 35 can connect to the worktable 34 and the second turnover frame 31 to support the worktable 34. For example, the support element 35 may have an elongated shape and extend perpendicular to the longitudinal direction L. One end of the support element 35 may engage with the worktable 34, and the other end of the support element 35 may engage with the second turnover frame 31. Preferably, the second turnover cart 3 may include multiple support elements 35, for example, multiple support elements 35 may be arranged side by side in the longitudinal direction L.
